1 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added STATS command to the protocol after all, to return
4 various statistical information about the network. It can
5 be used by clients to retrieve statistical information, and
6 servers may use it to to fetch cell and network wide
7 statistics from router. Updated the protocol specs and
8 implemented it to the server. Protocol TODO #16.
9 Affected files are lib/silccore/silccommand, silcd/command.[ch],
10 silcd/command_reply.[ch].
12 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
14 * The LIST command reply in client libary now adds new channel
15 entry if the returned channel doesn't exist yet in cache,
16 and returns the channel entry to the application in the
17 command_reply client operation. Affected file is
18 lib/silcclient/command_reply.c.
20 * Changed the channel message payload's MAC generation to
21 include the IV in the MAC as well. This way all relevant
22 parts of the channel message payload are authenticated also
23 with the channel message MAC (and not only by packet MAC).
24 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
25 Affected file is lib/silccore/silcchannel.c.
27 * Fixed the SKE to save the remote version, since the
28 silc_ske_parse_version mistakenly checked wrong version,
29 after it replaced the start payload. Affected files are
30 lib/silcske/silcske.[ch].
32 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
34 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
35 string utility functions. Added there also new functions
36 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
37 Affected files lib/silcutil/silcstrutil.[ch].
39 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
40 files are lib/silcutil/silcstrutil.[ch].
42 * Defined that the security property fields in SKE SHOULD be
43 UTF-8 encoded, defined that version string MUST be US-ASCII
44 encoded, defined that passphrases sent in connection
45 authentication protocol MUST be UTF-8 encoded. Implemented
46 these to the client and server. Defined also that other
47 passphrases sent in the protocol MUST be UTF-8 encoded.
48 Affected files are lib/silcske/silcske.c,
49 lib/silcclient/protocol.c, silcd/protocol.c,
50 silcd/serverconfig.c, and lib/silccore/silcauth.c.
52 * Changed the silc_client_close_connection interface to not
53 need the SilcSocketConnection which should not be visible
54 to application. Affected files are lib/silcclient/client.c
55 and lib/silcclient/silcclient.h.
57 * Rewrote the text for Private Message Key Payload in the
58 protocol specification. Protocol TODO #11.
60 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
62 * Upgraded the protocol version to 1.1, updated protocol specs
65 * Added the nickname as new argument to NICK_CHANGE notify and
66 added it to protocol specs and implemented it to client and
67 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
68 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
69 lib/silcclient/client_notify.c.
71 * Added the killer's client ID to the KILLED notify and added
72 it to protocol specs and implemented it to client and server.
73 Protocol TODO #13. Affected files are silcd/command.c,
74 silcd/packet_receive.c, packet_send.[ch],
75 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
76 The killer's client entry is now returned to application in
77 the `notify' client operation.
79 * Fixed the Max Argument fields that had too large value set
80 in the protocol specs. Protocol TODO #14.
82 * Added the LEAVE command reply to return the ID of parted
83 channel. Updated protocol specs and implemented it to the
84 client and server. Protocol TODO #15. Affected files are
85 silcd/command.c, lib/silcclient/command_reply.c. The channel
86 entry is now returned to application in the `command_reply'
89 * Rewrote the version SKE version checking in client libary
90 and in server to use the silc_parse_version_string. Affected
91 files are lib/silcclient/protocol.c, silcd/protocol.c.
93 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
94 commands that was missing it, and updated protocol specs and
95 the server implementation. Protocol TODO #10. The affected
96 file is silcd/command.c.
98 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
99 generic reply to a generic request (REQUEST flag), and
100 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
101 way. A draft-riikonen-silc-flags-payloads-00.txt is written
102 to define the payload for DATA flag. Added the flags to
103 the implementation. Protocol TODO #9. Affected file is
104 lib/silccore/silcchannel.h.
106 Changed the client library to return the message length
107 to application as well in the channel_message and private_message
108 client operations. Affected files are
109 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
110 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
111 and lib/silcclient/client_ops_example.c.
113 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
114 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
115 the channel. Updated protocol specs and impelemented this
116 to client and server. Protocol TODO #6. Affected files are
117 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
118 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
120 Added new options m and M to CMODE command in Irssi SILC
121 client to set these modes.
123 * Deprecated all administrative commands from SILC protocol
124 since they are highly implementation specific commands.
125 Updated protocol specs. Moved the old commands in
126 implementations to private range of command types. Affected
127 files are silcd/command.c, lib/silcclient/command.c and
128 lib/silcclient/command_reply.c. Protocol TODO #8.
130 * Fixed a bug in server where sending unknown command crashes
131 the server. Affected file silcd/command.c.
133 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
135 * Added SILC_PROTOCOLVERSION macro to check protocol version
136 of a socket connection. The affected file is
137 lib/silcutil/silcsockconn.h.
139 * Added better error logging in rekey protocol. Affected file
142 * Do not check public key types in SKE during rekey. Affected
143 file lib/silcske/payload.c.
145 * Fixed the rekey protocol with PFS, which was totally broken.
146 Affected file silcd/protocol.c.
148 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
150 * Some client implementations quit network by doing first LEAVE
151 and then immediately SIGNOFF (like Bombyx). We now do check
152 after a short time after LEAVE notify and check whether the
153 client is still valid after LEAVE, and if not we remove it from
154 cache. Affected file is lib/silcclient/client_notify.c.
156 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
158 * Merged version 1.1.4 of zlib. Even if it not currently in use,
159 it's good not to have security holes here.
161 * Fixed a negative refcount situtuation for the config context.
162 Affected file is silcd/serverconfig.c.
164 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
166 * ROBOdoc documented lib/silcutil/silcutil.h.
168 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
170 * Optimized even more the SilcPacketContext structure. Now
171 totally saved 16 bytes of memory per context after optimization.
172 Affected files are lib/silccore/silcpacket.[ch].
174 * Made strict checks for valid SILC IDs. Affected file is
175 lib/silccore/silcid.c.
177 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
179 * Changed the object argument for silc_cipher_register,
180 silc_hash_register, silc_hmac_register and silc_pkcs_register
181 to const. Affected files are lib/silccrypt/silccipher.[ch],
182 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
184 * Changed the silc_get_username and silc_get_real_name to
185 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
187 * Fixed the Irssi SILC Client to use the silc_get_username and
188 silc_get_real_name insted of glib routines since the glib
189 routines only corrupt stack. Fixes the Irssi SILC to work in
190 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
192 * Fixed the Irssi to not use g_get_home_dir since it crashes
193 or returns garbage on cygwin and corrupts stack. Added function
194 get_home_dir to Irssi routines. Affected files are
195 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
197 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
199 * Made some structure optimizations. SFTP memory FS MemFSEntry
200 entry structure. Optimized SilcTask structure. Optimized
201 SilcPacketContext structure.
203 Affected files lib/silcsftp/sftp_fs_memory.c,
204 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
206 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
208 * And yet again reverted back the config thing since Johnny
209 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
212 * Fixed memory leaks from config object. Affected files are
213 silcd/serverconfig.[ch].
215 * Added support for adding new connections to the server in rehash.
216 After rehash they take effect.
218 Added support for changing the maximum allowed connections in
219 rehash. The number can grow but going smaller is not supported.
221 Added function silc_server_num_sockets_by_remote to the
222 silcd/server_util.[ch].
224 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
226 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
228 * Added preliminary checking during config parsing for a valid
229 public/private key and removed further checks in the code.
230 Affected files are silcd/serverconfig.[ch], server.c.
232 * Moved functions silc_server_drop() and silc_server_daemonise()
233 from server.c to silcd.c since they are stricly related to
234 the application activity.
236 * Reverted a small part of the automatic ref/unref since
237 it caused a double unref in some situations. Affected
238 files are silcd/silcd.[ch], server.c, serverconfig.c.
240 * Added some .cvsignore files in the lib directory.
242 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
244 * Fixed silc_net_gethostbyaddr to correctly resolve by
245 address. Affected file lib/silcutil/silcnet.c.
247 * Fixed the notify relaying to client. The HMAC to be used
248 with relayed packets ws wrong and caused decryption failure
249 at the client end. Affected file is silcd/packet_receive.c.
251 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
253 * Created new branch silc_protocol_1_0_branch.
255 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
257 * Changed the silc_server_config_* routines to be SilcServer
258 independent. They are now officially application specific code
259 and not part of generic server implementation. Affected files
260 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
262 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
264 * Added automatic referencing of config context in the
265 silc_server_config_alloc, and automatic unreferencing in the
266 silc_server_config_destroy. Affected files are
267 silcd/serverconfig.[ch], silcd/silcd.c.
269 * Fixed the silc_log_quick handling in the logging routines.
270 It didn't log quickly when it was TRUE. Affected file is
271 lib/silcutil/silclog.c. Also the flush delay was set even
272 if it was 0 in config file. Affected file is
273 silcd/serverconfig.c.
275 * Added support for changing key pair of the server in rehash.
276 Affected file silcd/server.c.
278 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
280 * Fixed the TOPIC_SET notify to not cras. It changed the topic
281 too early, before getting the channel entry. Affected file
282 is silcd/packet_receive.c.
284 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
286 * Added functions silc_server_config_[ref/unref], these are used
287 to prevent that the config object is destroyed.
289 No longer directly affect global variables silc_log_quick and
290 silc_log_delay, they are first cached inside the config object
291 and then applied with silc_server_config_setlogfiles().
293 silc_server_config_set_defaults() is now internal to
294 serverconfig.c, there are no reasons to show this internal stuff
297 Affected files are silcd/serverconfig.[ch].
299 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
300 fprintf's to stderr, since some code may be executed again after
301 the server went into the background. Affected files are
304 * Added rehash support. Added function silc_server_rehash() that
305 will perform all the basic tasks of the rehashing procedure.
307 * Added command line option `-x, --hexdump'. This will enable the
308 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
309 The option `--hexdump' implies `--debug'.
311 * Fixed a bad bug in the logging APIs (silcutil library) where
312 the application would crash after calling silc_log_reset_all().
314 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
316 * Fixed the KICKED notify handling in client library to
317 correctly remove the channel and all entries from the
318 channel when I was kicked. This bug crashed the client.
320 Fixed yet another but in KICKED notify handling to remove
321 the kicked client correctly from the channel.
323 Affected file is lib/silcclient/client_notify.c.
325 * Fixed a minor bug in looking up correct client entry
326 in KICKED notify in server. Affected file is
327 silcd/packet_receive.c.
329 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
330 sources correctly to distribution. Fixes --with-gmp option.
332 * Removed the manual rehashing from ID Cache, and changed it
333 to use the SILC Hash Table's auto rehash feature. Affected
334 file is lib/silccore/silcidcache.c.
336 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
338 * Fixed a bug in the silc_client_nickname_format function that
339 handles the multiple same nickname formatting. Two clients
340 with same nickname caused problems after the first one left
341 and rejoined. It didn't format the nickname correctly.
342 Affected file is lib/silcclient/idlist.c.
344 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
346 * Don't change the topic if olod topic is same as new one.
347 Affected file is silcd/packet_receive.c.
349 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
351 * Added cross-reference support to the SILC Documentation
352 generator. All types across all HTML files are now cross-
353 referenced. Affected files util/robodoc/generator.c and
354 scripts/silcdoc/silcdoc.
356 * Added file lib/silcutil/silctypes.h to include all the
357 arithmetic type definitions and some macros. Removed
358 includes/bitmove.h and moved macros to silctypes.h.
360 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
362 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
364 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
366 * Added `type' argument to silc_id_payload_parse_id function which
367 now returns the type of the ID to the sent pointer. Affected
368 file is lib/silccore/silcid.[ch].
370 * Added check for CMODE_CHANGE notify type that mode change is
371 allowed by the sender. Affected file silcd/packet_receive.c.
373 * Added check for CUMODE_CHANGE notify type that mode change is
374 allowed by the sender. Affected file silcd/packet_receive.c.
375 Added the ID type as CUMODE_CHANGE notify type as argument
376 to the `notify' client operation. Affected files are
377 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
379 * Added function silc_client_add_server to the client library.
380 Added support for resolving also channel and server info when
381 received unknown entity in notify packet. Affected files are
382 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
384 * Added function silc_command_get_status to return the command
385 status from the command reply's argument payload. Affected files
386 are lib/silccore/silccommand.[ch].
388 * Added check for KICKED notify type that the kicking is
389 allowed by the client. Affected file silcd/packet_receive.c.
391 * Created function silc_get_input which can be used to get input
392 (echo on or off) from user on command line. Affected files are
393 lib/silcutil/silcutil.[ch].
395 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
397 * Optimized silc_server_packet_relay_to_channel function.
398 Added new function silc_channel_message_payload_encrypt which
399 can be called directly if channel message payload needs to
400 be encrypted and is already encoded (no need to call _encode
401 function). Packet relaying is now done by router without any
402 extra memory allocations. Affected files are
403 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
406 * Fixed the INVITE notify handling. It took wrong arguments
407 as invite list and invite delete. Affected file is
408 silcd/packet_receive.c.
410 * Added check for TOPIC_SET notify type that the topic change is
411 allowed by the client. Affected file silcd/packet_receive.c.
413 * Added check for INVITE notify type that inviting is allowed by
414 the client. Affected file silcd/packet_receive.c.
416 * Changed the silc_server_client_on_channel to return the
417 SilcChannelClientEntry as well. Moved the function
418 silc_server_check_cmode_rights to server_util.[ch].
419 Affected files are silcd/server_util.[ch], silcd/command.c.
421 * Added function silc_server_check_umode_rights to check whether
422 changing client's user mode is allowed. Added check for
423 UMODE_CHANGE notify type that the umode change is allowed
424 by the client. Affected files are silcd/server_util.[ch],
425 silcd/packet_receive.c and silcd/command.c.
427 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
429 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
430 ID length. It ignored that ID can be IPv6 based as well.
431 Affected file lib/silccore/silcpacket.h.
433 * Fixed the silc_id_id2str and silc_id_str2id to take the
434 IPv6 address offset's into consideration. Affecte file is
435 lib/silccore/silcid.c.
437 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Fixed the internal Unix scheduler functions to check for
440 NULL context they may receive. The affected file is
441 lib/silcutil/unix/silcunixschedule.c.
443 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
445 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
446 can specify different directory with --home command line
447 parameter. Affected files irssi/src/silc/core/client_ops.c,
450 * SILC-specific commands aren't now executed if the active server
451 isn't of SILC-type, so there won't be problems with having
452 IRC and SILC protocol support in same client. Affected files
453 irssi/src/silc/core/silc-channels.c, silc-servers.c,
456 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
458 * Improved the signal support in SILC Schedule. Added new
459 function silc_schedule_signal_call which is used by application
460 to mark a signal to be called. It is now safe to perform
461 any kind of tasks in signal callbacks since it is guaranteed
462 that the application specified signal callback is called
463 after the signal is over. Affected files are
464 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
466 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Added `name' field to SilcChannelPrivateKey to represent
469 application given name for the key. Moved also the context from
470 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
471 Added the `name' argument also to the function
472 silc_client_add_channel_private_key.
474 Added function silc_client_current_channel_private_key to set the
475 current channel private key in use.
477 Added "change" command to KEY command which can be used to change
478 the current channel private key. Bound the command also to
481 Also affected files lib/silcclient/client_channel.c,
482 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
484 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
486 * Added silc_rng_get_byte_fast function in to the
487 lib/silccrypt/silcrng.[ch].
489 * Changed the interface of silc_packet_assemble and the
490 silc_packet_send_prepare. If silc_packet_assmble is now
491 called the application does not call silc_packet_send_prepare
492 because the library will call it automatically. These
493 interfaces now also return a reference to the outgoing buffer
494 which includes the assembled packet, which the application can
495 use to encrypt the packet.
497 Affected files are lib/silccore/silcpacket.[ch],
498 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
499 silcd/packet_send.c, server_backup.c and packet_receive.c.
501 * Fixed a packet sending bug on very high load, where outgoing
502 packet queue wasn't handled correctly and packets got corrupted.
503 Affected files are lib/silcutil/*/silc*sockconn.c,
504 lib/silcclient/client.c and silcd/server.c.
506 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
508 * Added macro SILC_PACKET_DATALEN which can be used during
509 packet assembling to check whether the data to be added to
510 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
511 len is truncated until it fits it.
513 Added checks for maximum length of channel message payload and
514 private message payload also.
516 Added checks for maximum packet length in server and in
519 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
520 lib/silcclient/client.c, lib/silccore/silcchannel.c and
521 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
522 lib/silcclient/client_prvmsg.c.
524 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Added silc_server_packet_queue_purge call to the
527 silc_server_disconnect_remote to assure that all data in the
528 queue before disconnecting is sent to the network. Affected
531 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
533 * Added the deleting of server's own ID cache entry to the
534 silc_server_free function. Free also everything else that
535 has been allocated in silc_server_init. The affected file
538 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
540 * Added functions silc_parse_version_string, silc_version_to_num,
541 and silc_ske_parse_version to parse SILC protocol style version
542 strings. Affected files lib/silcutil/silcutil.[ch] and
543 lib/silcske/silcske.[ch].
545 * Added new configuration params: version_protocol, version_software
546 and version_software_vendor to specify what version the remote
547 host must at least be to be able to connect to server. The vendor
548 string can be regex matched too. Added new function
549 silc_server_connection_allowed to check maximum number of allowed
550 connections, and allowed versions for incoming connections.
551 Affected files are silcd/server.c, server_util.[ch] and
554 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
556 * Added preliminary support for signals in scheduler. The
557 signals we care about are now blocked always when the scheduler
558 is locked. This way we can synchronise the use of signal with
559 scheduler. It is guaranteed that when signal occurs the scheduler
560 is not locked, and thus new tasks can be safely added to the
563 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
564 to silc_schedule_internal_init and silc_schedule_internal_uninit.
565 Added new platform specific routines
566 silc_schedule_internal_signals_[un]block and
567 silc_schedule_internal_signal_[un]register.
569 Added new functions to SILC Schedule API:
570 silc_schedule_signal_[un]register. Each signal that application
571 is going to use should be registered to the scheduler.
573 Affected files are lib/silcutil/silcschedule.[ch],
574 lib/silcutil/*/silc*schedule.c.
576 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
578 * Check for unauthenticated client and server in the
579 silc_server_new_client and silc_server_new_server functions.
580 Affected file silcd/packet_receive.c.
582 * Added function silc_string_is_ascii to check whether given
583 string is 7-bit ASCII string. Affected files are
584 lib/silcutil/silcutil.[ch].
586 * Added function silc_id_is_valid_server_id into the
587 silcd/serverid.c and added checking for valid Server ID's in
588 silc_server_new_server. The Server ID must always be based
589 on the server's public IP address.
591 * Added logging of DISCONNECT packet message in the server.
592 Affected file silcd/server.c.
594 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
596 * Changed all library interfaces that use Global RNG to also
597 accept SilcRng as argument. Affected files are
598 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
599 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
600 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
601 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
604 * Added function silc_pkcs_generate_key to the
605 lib/silccrypt/silcpkcs.[ch] for applications so that they
606 don't need to do pkcs->pkcs->init calls anymore.
608 * Remove SilcSocketConnection from the SFTP API since it really
609 wasn't needed there. The application has the information
610 saved in its contexts anyway and the SFTP layer doesn't need
611 know about it. Affected files lib/silcsft/silcsftp.h and
612 lib/silcsftp/sftp_[server/client].c.
614 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
615 The SilcSimContext is not SilcSim.
617 * Fixed possible buffer overflows in silc_id_render in the
618 lib/silcutil/silcutil.c.
620 * On EPOC the global crypto module lists are not used at all
621 in the crypto library. Added support for using the constant
622 algorithm list on EPOC. Affected files are
623 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
626 * Fixed the handling of third parameter of KICKED notify, since
627 it was mistakenly updated to SILC Protocol 1.0 even though it
628 is to be included in 1.1. Since it is not in 1.0 it is not
629 mandatory, and this fix now handles it only if it is provided,
630 and it is not error if it is not provided. Affected file
631 lib/silcclient/client_notify.c.
633 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
635 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
636 client. Affected file irssi/src/silc/core/client_ops.c.
638 * Merged with Irssi 0.8.4 from irssi.org CVS.
640 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
642 * Check for valid socket connection in client entries before
643 sending any messages. Fixes a crash, but doesn't fix some
644 other underlaying bug that is lurking there. Affected
645 file silcd/packet_send.c.
647 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
649 * $usermode, $cumode and $cumode_space expandos shouldn't do
650 anything with non-SILC server records. Affected file
651 irssi/src/silc/core/silc-expandos.c
653 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Fixed the silc_net_check_[host/local]_by_sock to support
656 IPv6 bound sockets as well. Now they can return IPv6 addresses
657 as well. Affected file lib/silcutil/silcnet.c.
659 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
660 Affected lib/silcutil/unix/silcunixnet.c.
662 * Fixed ID rendering (at least on some platforms, not NetBSD)
663 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
665 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Added silc_hash_public_key and silc_hash_public_key_compare
668 functions to be used with SilcHashTable. They can be used to
669 hash public keys and compare public keys in hash table. Affected
670 file lib/silcutil/silcutil.[ch].
672 * Added support for specifying multiple public keys for Client
673 connection section in server configuration file. This makes it
674 possible to accept multiple public keys from same host, or to
675 make a section that accepts any incoming host, and have the
676 accepted public keys listed in the section.
678 Added functions silc_sever_[find/get]_public_key, added the
679 support for this actually to all connection sections but only
680 the Client section is currently allowed to specify multiple
683 Affected files are silcd/server.c, server_internal.h,
684 command.c, protocol.c, server_util.[ch], packet_receive.c.
686 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
688 * Merged Irssi 0.8.2 from irssi.org CVS.
690 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
692 * If silc_debug is TRUE, also output standard logging messages
693 to stderr with the debug output.
695 Made silc_log_reset_all() flushing all channels before returning.
696 Also fixed some documentation typos.
698 Affected files are lib/silcutil/silclog.[ch].
700 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
702 * Fixed the server to check correctly the amount of connections
703 from single host, by checking also the type of the connection.
704 Fixed also the comparison of number of connections and number
705 of allowed connections. Affected files are silcd/server.c,
708 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
710 * Fixed the USERS command reply to save the user's mode on the
711 channel as well. Fixed JOIN command reply to check whether a
712 client is on channel already and not join it twice. Affected
713 file lib/silcclient/command_reply.c.
715 * Added new file silc-expandos.c into irssi/silc/core/ to return
716 various stuff for various signal for the statusbar etc. updating.
717 Now Irssi SILC client prints channel user modes etc. on the
720 * The user mode (like server/router operator changes) is now shown
721 on the Irssi SILC client's statusbar. The affected files are
722 irssi/src/silc/core/client_ops.c, silc-expandos.c.
724 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
726 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
727 to SILC_SCHEDULE_[UN]LOCK macros.
729 * Added more error printing to logs in server code. Affected
730 files silcd/server.c and silcd/protocol.c.
732 * Fixed -S option parsing in Irssi SILC Client. Affected file
733 irssi/src/silc/core/silc-core.c.
735 * Added silc_buffer_alloc_size function. Affected file is
736 lib/silcutil/silcbuffer.h.
738 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
740 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
741 constants. Affected files in
742 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
745 * Changed the internal SFTP Memory FS table to const. Affected

748 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
750 * Fixed the buffer formatting and unformatting routines to
751 check the size of 64 bits types with sizeof(). Affected
752 file is lib/silcutil/silcbuffmt.c.
754 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
756 * Removed 0.6.x backwards support.
758 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
760 * Changed all integer type names:
761 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
762 to avoid collisions with other libraries using same type names
765 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
767 * Added `prefer_ipv6' argument to the functions
768 silc_net_gethostbyname[_async]. If it is TRUE it will return
769 IPv6 address over IPv4. If FALSE IPv4 address is returned
770 even if IPv6 address was found. Affected files
771 lib/silcutil/silcnet.[ch].
773 * Added support silc_net_create_connection[_async] to fallback
774 to IPv4 address if IPv6 address could not be used (like if
775 it doesn't work on a specific system). Affected file in
776 lib/silcutil/unix/silcunixnet.c.
778 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

786 * Added automatic extern "C" { ... } for C++ compilers so the
787 application does not need to define them. Affected file
788 includes/silcincludes.h.
790 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
791 old name went against naming convention. Applications now
792 include "silcclient.h" instead of "clientlibincludes.h".
793 Removed includes/clientlibincludes.h, it is redundant now.
795 * Renamed includes/version.h to silcversion.h.
797 * Added really preliminary support for OS/2 into the util
798 library. Only thread & mutex API is implemented, others
799 are still to be implemented. Created the lib/silcutil/os2/
800 directory. Created also file includes/silcos2.h.
802 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Added preliminary BeOS support into the util library.
805 Created lib/silcutil/beos/, and implemented all the needed

811 * Added proper initializations to silc's irssi code, so it's
812 now possible to load it as module. Affected files
813 irssi/src/silc/core/silc-core.c,
814 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
816 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

825 * ROBOdoc documented lib/silcutil/silcmemory.h.
826 Added also new function silc_memdup.
828 * Removed lib/silcutil/silcbufutil.h and moved those routines
829 to the lib/silcutil/silcbuffer.h.
831 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
833 * Added `user_count' to the SilcChannelEntry which now tells the
834 number of users on the channel. The user count is now saved
835 in normal server of global channels as well. Affected files
836 silcd/server.c, idlist.h, packet_receive.c and command.c.
838 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
839 include file utility functions.
841 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
842 instead of calling directly OS routines.

849 client_entry->channels hash table everytime nick is changed.
850 Affected file lib/silcclient/client.c.
852 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
854 * ROBOdoc documented the lib/silcske/silcske.h, and improved
855 the SKE interface a bit.
857 * Fixed padding problem in PKCS#1. The padding was not actually
858 random since the random number generator was used incorrectly.
859 This security bug affects only when encrypting with PKCS#1, and
860 it is not currently used at all in SILC. SILC only use signing
861 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
863 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

880 Optimized the use of SKE Mutual flag usage. Use it only
881 if connection authentication protocol is not based in public
884 Renamed all SilcServerConfigSection* to SilcServerConfig*
885 to have a bit shorter names.
887 Affected files silcd/serverconfig.[ch], server.[ch], and
890 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

921 is now done in silc_core_init() which also fixes autoconnecting
924 Affected files irssi/src/silc/core/silc-core.c,
925 irssi/src/fe-text/silc.c.
927 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
929 * Added new configuration options and blocks:
930 keepalive_secs, reconnect_count, reconnect_interval,
931 reconnect_interval_max, reconnect_keep_trying and
932 require_reverser_lookup. Added ConnectionParam block, and
933 implemented the connection parameters when connecting as
934 initiator and when accepting connections as responder.
936 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
937 whether given configuration value has been given already.
939 Affected files silcd/serverconfig.[c], server.[c].
941 * Splitted the doc/example_silcd.conf.in. Separated the crypto
942 algorithm parts and created new file silcalgs.conf, that
943 is now included from the example_silcd.conf.in.
945 * Optimized the silc_server_connect_to_router_second to take
946 the connection configuration object from the SilcServerConnection
947 object instead of finding it during the connecting phase.
948 Added the configuration object to SilcServerConnection struct.
949 Affected files silcd/server_internal.h, server.c.
951 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
953 * Add the client on channel after it was resolved at the
954 channel message receiving, and it was not already on the
955 channel. Affected file lib/silcclient/client_channel.c.
957 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
959 * Fixed the public key authentication to allocate always the
960 destination signature buffer instead of using static buffer.
961 Affected file silcd/protocol.c.
963 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
965 * Unified the serverconfig.[ch]'s helper function interface.
966 Affected file silcd/serverconfig.[ch].
968 * Removed doc/example_silc.conf.in since it is redundant.
969 The make install will now install irssi/silc.conf file.
971 * Added new Passphrase and Publickey authentication methods to
972 config file, allowing both public key and passphrase based
973 authentication to be set at the same time.
975 Added `prefer_passphrase_auth' setting in config file which
976 can be used to set to prefer passwd auth if both passwd and
977 public key is set. If not set, public key is preferred.
978 This has effect only when being initiator (responder will try
981 Added support for authentication with passphrase and public key
982 at the same time. The passphrase is tried first always since
983 it is faster to check.
985 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
987 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1002 * The silc_cipher_register, silc_hash_register and
1003 silc_hmac_register now checks if the object to be registered
1004 is registered already. Affected files are
1005 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.

1033 * Fixed the file transfer's key agreement payload to include
1034 zero port also if the hostname is NULL because it could not
1037 Call file transfer monitor callback now also if error occurs
1038 during key agreement protocol.
1040 Changed the silc_client_file_send interface to return the
1041 SilcClientFileError instead of session id. The session ID
1042 is returned into pointer provided as argument.
1044 Check that the file exists locally before sending the
1045 file transfer request at all.
1047 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1049 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1055 irssi/src/silc/core/silc-channels.c.
1057 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1058 SILC_LOG_WARNING to give out Warning and not Error. Affected
1059 file lib/silcutil/silclog.c.
1061 * Fixed the channel message payload decryption in the function
1062 silc_channel_message_payload_decrypt to not modify the original
1063 buffer before it is verified that the message decrypted
1064 correctly. Otherwise, next time it is called with correct
1065 channel key it won't encrypt since the payload is corrupted.
1066 Affected file lib/silccore/silcchannel.c.
1068 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1070 * Do not constantly resize the window. A fix patch by cras.
1071 Affected file irssi/src/fe-text/screen.c.
1073 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1075 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1076 Affected file lib/silcutil/silcnet.c.
1078 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1080 * Fixed a bug in hash table internal routine for traversing
1081 the table with foreach callback. The current entry may
1082 become invalid in the callback but it was referenced after
1083 the callback returned.
1085 Do not allow auto rehashing of hash table during the
1086 silc_hash_table_foreach operation, for same reasons as it is
1087 not allowed for SilcHashTableList. Affected files are
1088 lib/silcutil/silchashtable.[ch].
1090 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1092 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1093 Win32 DLL. extern's in header files are now declared with
1096 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Fixed private message handling. It used some old code that
1099 caused the client to crash. Affecte file is
1100 lib/silcclient/client_prvmsg.c.
1102 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1104 * Added function silc_client_add_channel,
1105 silc_client_replace_channel_id, and removed functions
1106 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1107 from client library.
1109 * Added cross reference of the joined channels to the
1110 SilcClientEntry, and changed the SilcChannelEntry's
1111 users list to SilcHashTable. The affected files are
1112 lib/silcclient/idlist.[ch].
1114 * Fixed a bug in hash table tarversing. While the hash table
1115 is traversed with SilcHashTableList the table must not be
1116 rehashed. It is now guaranteed that auto rehashable tables
1117 are not rehashed while tarversing the list. Also defined that
1118 silc_hash_table_rehash must not be called while tarversing
1119 the table. Added function silc_hash_table_list_reset that must
1120 be called after the tarversing is over. The affected files are
1121 lib/silcutil/silchashtable.[ch].
1123 * Changed all hash table traversing to call the new
1124 silc_hash_table_list_reset in server and in client library.
1126 * Added function silc_client_on_channel to return the
1127 SilcChannelUser entry if the specified client entry is joined
1128 on the specified channel. This is exported to application as
1129 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1131 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Fixed founder regaining problem with JOIN command on normal
1134 server. The notify for mode change must be sent always and
1135 not only if !cmd->pending. Affected file silcd/command.c.
1137 * Fixed the WHOWAS command's reply sending to support the
1138 lists correctly. Affected file silcd/command.c.
1140 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1142 * When sending JOIN command to router for processing the
1143 sender's old command identifier was not saved back to the
1144 sender's command context, fixed now. The affected file is
1147 * Create the key in JOIN command of the router did not return
1148 the channel key, added check for this. Affected file is
1151 * Fixed a channel ID update bug in JOIN command reply. Do
1152 not directly upgrade the ID but call the function
1153 silc_idlist_replace_channel_id if the ID was changed.
1154 Affected file silcd/command_reply.c.
1156 * Fixed memory leaks from command calling if it would fail.
1157 Affected file silcd/command.c.
1159 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1161 * Applied patches from cras:
1163 Memory leak fixes around libaries, irssi window resize fix,
1164 new silclist.h and silcdlist.h, all extern inline changed to
1167 * Removed dotconf from lib/dotconf, not needed anymore.
1169 * Removed TRQ from lib/trq, not needed anymore.
1171 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1172 with server connections. Later this will be configurable
1173 in config file after new config file is done. Affected file
1176 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1178 * Fixed a crash in server related to channel announcements.
1179 Affected file silcd/server.c.
1181 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1183 * Fixed memory leaks in silc_server_create_new_channel*
1184 functions. Affected file silcd/server.c.
1186 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1187 which ID was changed. This way the router will send the
1188 user list for the channel again, and server won't be in
1189 desync in some rare circumstances. Affected file is
1190 silcd/packet_receive.c.
1192 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1194 * Check for NULL socket pointer in the function
1195 silc_server_packet_send_to_channel_real. Affected file
1196 silcd/packet_send.c.
1198 * Fixed the BAN notify handling to correctly remove ban
1199 list. Affected file silcd/packet_receive.c.
1201 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1203 * Fixed some header addition to Toolkit distribution in
1204 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1206 * Added lib/silcclient/client_ops_example.h as an template
1207 file for application programmers to quickly start using
1208 the SilcClientOperation functions in their application.
1209 Updated the lib/silcclient/README as well to tell about this
1210 nice file made available.
1212 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Call silc_server_remove_from_channels when removing client
1215 entry when NO_SUCH_CLIENT_ID was received. Affected file
1216 is silcd/command_reply.c.
1218 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Added server & router operator statistics updating. Affected
1221 file silcd/packet_receive.c and silcd/command.c.
1223 * Fixed the SERVER_SIGNOFF notify handling on normal server
1224 not to save the history information for clients. Same was
1225 fixed earlier in remove_clients_by_server function, but not
1226 here. Affected file silcd/packet_receive.c.
1228 * Raised the default connection-retry count from 4 to 7 in
1229 server. Affected file silcd/server.h.
1231 * Cancel any possible reconnect timeouts when we start the
1232 key exchange. Affected file silcd/server.c.
1234 * Do not reconnect on connection failure when SCONNECT was
1235 given. Affected files silcd/server.[ch].
1237 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1239 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1241 * Fixed the NICK command to always give the unformatted
1242 nickname to the one giving the NICK command. If unformatted
1243 nickname is cached already it will be formatted and the
1244 local entry will always get the unformatted nickname.
1245 Affected file lib/silcclient/idlist.c.
1247 * Fixed some double frees from client library commands.
1248 Affected file is lib/silcclient/command.c.
1250 * Fixed CUMODE command in server to assure that no one can
1251 change founder's mode than the founder itself, there was a
1252 little bug. Affected file silcd/command.c.
1254 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1256 * Removed the SilcClientCommandDestructor from the client
1257 libary, it is not needed anymore. Affected files are
1258 lib/silcclient/silcapi.h, command[_reply].[ch],
1259 client_notify, idlist.c.
1261 * Fixed GETKEY command to first resolve client, and then
1262 resolve the server only if the client was not found, instead
1263 of resolving both at the same time. Affected file is
1264 lib/silcclient/command.c.
1266 * Added silc_client_start_key_exchange_cb and lookup the
1267 remote hostname and IP address before starting the key
1268 exchange with server. The affected file is
1269 lib/silcclient/client.c.
1271 * The server's public key is now saved using the IP address
1272 of the server and not the servername for the filename.
1273 The hostname public key filename is checked as an fall back
1274 method if the IP address based filename is not found.
1276 Fixed the GETKEY command to save the fetched server key
1277 in correct filename.
1279 Print the remote server's hostname now when new key is
1280 received during connection process. Affected file is
1281 irssi/src/silc/core/client_ops.c.
1283 * Return always our own public key to the client if it asks
1284 for it with GETKEY command. Affected file silcd/command.c.
1286 * Removed the use_auto_addr variable from default config
1287 file since it was in wrong section. Affected file is
1290 * Fixed TOPIC_CHANGE notification to not route it when it
1291 was sent using silc_server_send_notify_to_channel function.
1292 Affected file silcd/command.c.
1294 * Fixed silc_server_send_notify_kicked to send the kicker's
1295 Client ID also, it was missing. Affected files are
1296 silcd/command.c, silcd/packet_send.[ch].
1298 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1300 * Do not save client history information in SERVER_SIGNOFF.
1301 Fixes the bug in normal server that it does not detect
1302 the client becoming valid after the server becomes back
1303 online. Affected file silcd/server_util.c.
1305 * Added `sock_error' field into the SilcSocketConnection
1306 context. When error occurs during socket operation (read
1307 or write) the error is saved. Added also new function
1308 silc_socket_get_error to return human readable socket error
1309 message. Affected files are lib/silcutil/silcsockconn.[ch],
1310 lib/silcutil/unix/silcunixsockconn.c, and
1311 lib/silcutil/win32/silcwin32sockconn.c.
1313 * The server now prints the socket error message in the
1314 signoff for client. Affected file silcd/server.c.
1316 * Fixed the `created' channel information sending from router
1317 to server in JOIN command. Checks now whether the channel
1318 really was created or not and set it according that.
1320 Fixed the JOIN command to use the client entry's current
1321 ID during the joining procedure instead of the one it sent
1322 in the command (it is checked though), since it can change
1323 between the packet processing and command processing, and
1324 would just case unnecessary pain in the client end. Affected
1325 file silcd/command.c.
1327 * Fixed a channel key payload sending to use correct channel
1328 ID when the server was forced to change the channel's ID by
1329 router. Router sent the key payload with the old Channel ID.
1330 Affected file silcd/packet_receive.c.
1332 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1334 * Call silc_server_save_channel_key only if the key payload
1335 was provided in the JOIN command's command reply. Affected
1336 file silcd/command_reply.c.
1338 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Fixed silc_mp_sizeinbase to return the value correctly with
1341 MPI. Affected file lib/silcmath/mp_mpi.c.
1343 * Fixed the stop_server signal to correctly stop the scheduler
1344 and gracefully stop the server when SIGTERM or SIGINT signals
1345 are received. Affected file silcd/silcd.c.
1347 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1349 * Simple handling of TERM and HUP signals. Also added some log
1350 flushing call around. Affected file is
1353 * Fixed small bugs in silclog.c. Now buffering output will take
1354 effect after 10 seconds since startup: This will ensure that
1355 no important startup messages are lost. Also output redirection
1356 will preserve original format ([Date] [Type] message).
1357 Affected file is lib/silcutil/silclog.c.
1359 * Added two options to the config file, in the logging section:
1360 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1361 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1363 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1365 * Do not print the warning about log files not being initialized
1366 more than once to avoid excess logging. Affected file is
1367 lib/silcutil/silclog.c.
1369 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1370 the SIM copying in make install in Makefile.am.pre.
1372 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1374 * Rewritten silclog APIs. Globally interesting changes follows:
1375 silc_log_set_files() changed to silc_log_set_file().
1376 silc_log_set_callbacks() changed to silc_log_set_callback().
1377 ROBOdoc documented silclog header file.
1378 SilcLogCb now returns bool to wether inihibit the default
1379 handler or not (to keep the old behaviour return always TRUE).
1380 The new APIs should also fix the problem of the
1381 silcd_error.log file that was written in the current directory.
1384 Log files streams will remain opened after silc_log_set_file()
1385 call, means less CPU usage notably on high traffic servers.
1386 File streams are now full buffered, and flushed to the disk
1387 every 5 minutes, lesses HD activity and CPU usage.
1388 Messages can be redirected, allowing admins to configure
1389 one single logfile for all server messages.
1390 the silc_log_quick global variable to activate fast-logging.
1391 Affected files lib/silcutil/silclog.[ch]
1393 * Changed some code to conform new silclog APIs. Affected
1394 files are doc/example_silcd.conf.in, silcd/server.c
1395 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1398 * Fixed a memory leak that could occur in some situations.
1399 Affected file silcd/serverconfig.c.
1401 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1403 * Added the silc_client_del_client to remove the client from
1404 all channels as well. Affected file lib/silcclient/idlist.c.
1406 * Fixed the client library to correctly remove the client
1407 from all channels when the client entry is being destroyed.
1408 Affected file lib/silcclient/client_notify.c, command.c.
1410 * Added auto-nicking support to the client library. If the
1411 applicatio now sets client->nickname it will be sent to the
1412 server after connecting by the library. This way for example
1413 SILCNICK (or IRCNICK) environment variables will have effect
1414 and always change the nickname automatically to whatever
1415 it is wanted. Affected file lib/silcclient/client.[ch].
1417 * Renamed silc_server_command_bad_chars to the
1418 silc_server_name_bad_chars and moved it to the
1419 silcd/server_util.[ch]. Added also new function
1420 silc_server_name_modify_bad to return nickname that
1421 includes bad characters as new nickname without those
1422 bad characters. This check and modify is now used in
1423 silc_server_new_client when the username is initially set
1424 as nickname, so it must be checked to be valid nickname.
1425 Affected file silcd/packet_receive.c.
1427 * The nickname length is now taken from the packet for real
1428 and not trusted to strlen() since it clearly can return
1429 wrong length for nickname including bad characters. This
1430 also applies to channel names. Affected file silcd/command.c.
1432 * Removed the lib/silcsilm/modules directory. Modules are now
1433 compiled into the lib/silcsim. Fixed the copying of the
1434 modules to follow symbolic links in Makefile.am.pre.
1436 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1438 * Fixed silc_string_regexify list creation. Fixes bugs with
1439 BAN and INVITE commands in server. The affected file is
1440 lib/silcutil/unix/silcunixutil.c.
1442 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Removed the command destructor entirely from the server's
1445 command and command reply routines. It is not needed, and
1446 its usage was buggy and caused crashes. Affected files are
1447 silcd/command[_reply].[ch].
1449 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Cancel protocol and NULL sock->protocol if timeout
1452 occurred during protocol. Affected file silcd/server.c.
1454 * Cancel protocol timeouts always before calling the final
1455 callback, to assure that after final callback is called
1456 no other state will be called for the protocol anymore.
1457 Affected file silcd/protocol.c.
1459 * Print error log if incoming connection configuration could
1460 not be found. Affected file silcd/server.c.
1462 * Fixed JOIN command to correctly save the founder mode
1463 to the client on normal SILC server, when the channel
1464 was created by the router. Affected file silcd/command.c.
1466 * Fixed LIST command (hopefully) to send correct reply
1467 packets. Affected file silcd/command.c.
1469 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1471 * The silc_packet_receive_process now returns FALSE if the
1472 read data was invalid packet, and TRUE if it was ok.
1474 The server now checks that if unauthenticated connection
1475 sends data and its processing fails the server will close
1476 the connection since it could be a malicious flooder.
1478 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1480 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Make sure the warning about error opening a log file is
1483 printed only once and not everytime it fails (produces
1484 too much useless log). Affected file lib/silcutil/silclog.c.
1486 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1488 * Made the silc_server_daemonise() function more readable.
1489 Affected file silcd/server.c.
1491 * Pid file is now optional, the user may comment it out from
1492 the config file. Removed define SILC_SERVER_PID_FILE, we
1493 don't need a default any longer. Affected file
1494 configure.in.pre, lib/Makefile.am.pre.
1496 * Make some use of the pid file. The server now dies at startup
1497 if it detects a valid pid file on his path. The server would
1498 die anyway in this circumstance, because of the bind() failure.
1499 Affected file silcd/silcd.c.
1501 * No longer compiling lib/dotconf.
1503 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Fixed JOIN command parsing not to crash. Affected file
1506 lib/silcclient/command.c.
1508 * Fied the NICK_CHANGE notify to add the new client entry
1509 even it is resolved. This removes an <[unknown]> nick
1510 thingy bug in the client. Affected file is
1511 lib/silcclient/client_notify.c.
1513 * Do not try to allocate 0 bytes (efence does not like it)
1514 in lib/silccore/silccomand.c when encoding payload.
1516 * Do not take IRCNICK as nickname in Irssi SILC client since
1517 it is not possible to set nickname before hand connecting
1518 the server (TODO has an entry about adding auto-nicking
1521 * Changed the silc_server_command_pending to check whether
1522 there already exists an pending entry with the specified
1523 command, command identifier and pending callback. This is
1524 to fix IDENTIFY and WHOIS related crashes that may register
1525 multiple pending commands with same identifier. Affected
1526 file silcd/command.c.
1528 * Fixed the server to reconnect to the router even if it
1529 was already reconnecting and EOF was received. This to
1530 fix a possibility that the server wouldn't ever try to
1531 auto-reconnect to the router. Affected file silcd/server.c.
1533 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1535 * Fixed the server's password authentication to use the
1536 length of the locally saved password, and not the one
1537 sent in the packet. Affected file silcd/protocol.c.
1539 * Fixed same password authentication problem in the
1540 Authentication Payload handling routines in
1541 lib/silccore/silcauth.c.
1543 * Yet another password authentication problem fixed with
1544 channel password handling in silcd/command.c.
1546 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * If first character of string in silc_parse_userfqdn is '@'
1549 then do not parse it. Affected file is
1550 lib/silcutil/silcutil.c.
1552 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Fixed minor bug in IDENTIFY command reply sending, which
1555 caused various weird problems during JOIN when it was
1556 resolving names for users. Affected file silcd/command.c.
1558 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * Fixed the IDENTIFY command reply sending to chech better valid
1561 clients. It was possible to send incomplete list of replies.
1562 Affected file silcd/command.c.
1564 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * Added silc_client_command[s]_[un]register functions now to
1567 dynamically register the commands in client library. Removed
1568 the static table of commands. This allows the client library
1569 to call commands without causing the application to know about
1570 what commands library has called.
1572 Removed the INFO command reply kludge to detect when the command
1573 was called by library. Now library use its own command reply
1574 function for INFO command.
1576 Added function silc_client_command_call to call a command.
1577 Application can use it to call command, not access the structure
1580 Now all commands that are sent by the client library (not
1581 explicitly sent by application) use own command reply functions.
1583 Affected files around lib/silcclient/ and in
1584 irssi/src/silc/core/.
1586 * Fixed the WHOIS command reply sending to chech better valid
1587 clients. It was possible to send incomplete list of replies.
1589 Fixed the WHOIS and IDENTIFY to send the request to router
1590 if normal server did not do it and did not find any results.
1592 Affected file silcd/command.c.
1594 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Moved the internal data from SilcClient context into its
1597 own file, not accesible to application. Affected files
1598 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1599 and other files in client library.
1601 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Added doc/examples installation target in Makefile.am.pre.
1606 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1608 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1609 commands the found client entry will be removed from the
1610 cache, after notifying application about the error. Affected
1611 file lib/silcclient/command_reply.c.
1613 * Changed the /MSG to check for exact nickname user gave, and
1614 not let `nick' match `nick@host' if it is only one found. Now,
1615 user must type the exact nickname (like nick@host2) even if
1616 there are no more than one same nicks found. This is to avoid
1617 a possibility of sending nickname to wrong nickname since
1618 `nick' could match `nick@host'. Affected file is
1619 irssi/src/core/silc-servers.c.
1621 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Do not print "you are now server operator" or similar when
1624 giving /away command. Affected files are
1625 irssi/src/silc/core/client_ops.c, silc-servers.h.
1627 * Made the silc_server_command_pending_error_check to send
1628 the same command reply payload it received back to the
1629 original sender of the command. This way all arguments
1630 that was received by the server will be received by the
1631 client too. Affected file silcd/command.c.
1633 * Added the silc_idcache_add to return the created cache entry
1634 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1636 * Add global clients to expire if they are not on any channel.
1637 This is because normal server will never know if they signoff
1638 if they are not on any channel. The cache expiry will take
1639 case of these entries. This is done by normal servers only.
1640 The affected files are silcd/command_reply.c,
1641 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1643 * If server receives invalid ID notification for WHOIS or
1644 IDENTIFY and the ID exists in the lists, it is removed.
1645 Affected file silcd/command_reply.c.
1647 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1648 in client then client entry that it matches is searched and
1649 the nickname is printed on the screen for user. Affected
1650 file irssi/src/silc/core/client_ops.c.
1652 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Use cache entry expire time in the LIST command reply to
1655 purge old entries from the cache after the LIST command
1656 reply has been received. This way we don't have non-existent
1657 entries in the cache for too long. Affected file is
1658 silcd/command_reply.c.
1660 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * If we are normal server, and we've not resolved client info
1663 in WHOIS or IDENTIFY from router, and it is global client,
1664 we'll check whether it is on some channel. If it is not
1665 then we cannot be sure about its validity and will resolve it
1666 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1667 file silcd/command.c.
1669 * Search channel by name (if possible) rather than by ID
1670 in IDENTIFY command's command reply. Affected file is
1671 silcd/command_reply.c.
1673 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1676 Updated specs and implemented it. Affected file silcd/command.c,
1677 silcd/packet_send.c and silcd/packet_receive.c.
1679 * Implemented the <founder auth> payload handling in the JOIN
1680 command. If provided all conditions for channel joining
1681 except requirement to provide correct passphrase can be
1682 overrided by the channel founder. Updated the protocol specs.
1683 Affected file silcd/command.c.
1685 Added support for founder auth in JOIN command in client
1686 library. Fixed the parsing of the JOIN command now to support
1687 all options as they should be. The affected file is
1688 lib/silcclient/command.c.
1690 * Optimized the WHOIS and IDENTIFY commands to send the request
1691 to router only if it includes nicknames or other names. If
1692 they include only IDs then check the local cache first before
1693 routing. Affected file is silcd/command.c.
1695 * Added channels topic announcements. Affected file is
1696 silcd/packet_receive.c and silcd/server.c.
1698 * Fixed the silc_server_send_notify_topic_set to really destine
1699 the packet to channel. Affected file silcd/packet_send.c.
1701 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1702 library. Affected file lib/silcclient/client_notify.c.
1704 * Added UMODE announcements. Affected file silcd/server.c.
1706 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Memory leak fixes in:
1710 lib/silcutil/silcsockconn.c
1711 lib/silcske/silcske.c
1712 lib/silcske/groups.c
1714 lib/silccrypt/silcpkcs.c
1715 lib/silccore/silccommand.c
1716 lib/silccore/silcidcache.c
1721 * ROBOdoc documented the lib/silcske/groups.h file and a
1722 bit changed the interface for better.
1724 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1726 * Update the client entry context in the ID cache after
1727 nick change. Affected file lib/silcclient/command.c.
1728 Fixes the CUMODE command when regaining founder privileges,
1729 and a little WHOIS problem.
1731 * Fixed silc_net_gethostbyname to correctly call the
1732 inet_ntop. Affected file lib/silcutil/silcnet.c.
1734 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1736 * Added IPv6 support checking to the configure.in.pre, added
1737 also --enable-ipv6 option to override the check. Affected
1738 file configure.in.pre.
1740 * The silc_thread_create now calls the start function
1741 directly if threads support is not compiled in. Removes
1742 ugly #ifdef's from generic code. Affected files are
1743 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1745 * Added silc_net_gethostby[name/addr]_async to asynchronously
1746 resolve. Affected files are lib/silcutil/silcnet.[ch].
1748 * Added support for rendering IPv6 based server, client and
1749 channel IDs. Affected file lib/silcutil/silcutil.c.
1751 * Added support for creating IPv6 based server IDs. Affected
1752 file is silcd/serverid.c.
1754 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1756 * Added silc_net_gethostby[addr/name] into the
1757 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1758 routines. Added silc_net_is_ip[4/6]. Affected file is
1759 lib/silcutil/unix/silcunixnet.c. All routines that take
1760 address as argument now supports both IPv4 and IPv6 addresses.
1762 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1764 * Fixed LIST command reply sending in server. Affected file
1767 * Server now sends the kicker's client ID in the KICK notify
1768 to the kicked client. Affected file silcd/command.c.
1770 * The client library now parses the kickers client ID and
1771 UI displays it. Affected files lib/silcclient/client_notify.c
1772 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1774 * Made all payload parsing function prototypes consistent.
1775 They all take now const unsigned char * and uint32 pair as
1776 the payload data instead of SilcBuffer. Changes all around
1777 the source tree. Other unsigned char* -> const unsigned char*
1778 changes around the tree as well.
1780 * Optimized SFTP client and server packet sending not to
1781 allocate new buffer for each packet but to recycle the
1782 first allocated buffer. Affected files are
1783 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1785 * Optimized the SFTP client to use SilcList instead of
1786 SilcDList for requests, because it is faster. Affected file
1787 is lib/silcsftp/sftp_client.c.
1789 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1790 into lib/silccore/silcid.[ch].
1792 Renamed silcpayload.[ch] into silcargument.[ch].
1794 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * If client entry is deleted with active key agreement
1797 session, abort the session.
1799 The silc_client_abort_key_agreement now calls the completion
1800 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1802 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1805 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Don't use __restrict in older GCC's. Affected file is
1808 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1810 * silc_net_localhost now attempts to reverse lookup the
1811 IP/hostname. Affected file lib/silcutil/silcnet.c.
1813 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1814 command. It can be used to gain founder privileges at
1815 the same time when joining the channel.
1817 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1818 kicker's client ID as well. Updated protocol specs.
1820 Defined that the server must send SILC_COMMAND_IDENTIFY
1821 command reply with error status to client who sent
1822 private message with invalid client ID.
1824 Updated the protocol specification.
1826 * Added silc_server_send_command_reply to send any
1827 command reply. Affected file silcd/packet_send.[ch].
1829 * Added silc_id_payload_encode_data to encode ID payload
1830 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1832 * The server now send IDENTIFY command reply with error
1833 status if client ID in private message is invalid. Affected
1834 file silcd/packet_receive.c.
1836 * Save the server key file with server's IP address in
1837 the filename instead of hostname. The affected file is
1838 irssi/src/silc/core/client_ops.c.
1840 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1845 * Added libtool support for compiling shared objects in
1846 lib/silcsim. Affected file configure.in.pre and
1847 lib/silcsim/Makefile.am. Original patch by cras.
1849 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Pid file configuration, and server's config file fixes
1852 patch by toma. Updated CREDITS file.
1854 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed silc_client_channel_message to not try to decrypt
1857 the message twice if it resolved the destination client
1858 information. This could cause of dropping one channel
1859 message. Affected file lib/silcclient/client_channel.c.
1861 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1864 lib/silcclient/client.c. This function is used when the SILC
1865 Client is run under some other scheduler, or event loop or
1866 main loop. On GUI applications, for example this may be
1867 desired to used to run the client under the GUI application's
1868 main loop. Typically the GUI application would register an
1869 idle task that calls this function multiple times in a second
1870 to quickly process the SILC specific data.
1872 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1874 * Fixed silc_server_drop() for dropping the supplementary
1875 groups as well, this could cause a security hole on some
1878 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1883 * Write PID file after dropping privileges. Added -F option
1884 to run server on foreground. A patch by debolaz.
1885 Affected files silcd/server.c, silcd/silcd.c.
1887 * Fixed MOTD to return the MOTD file server name. Affected
1888 file silcd/command.c.
1890 * Added INFO command reply handling to the Irssi SILC Client.
1891 Affected file irssi/src/silc/core/client_ops.c.
1893 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Fixed the silc_idcache_list_* routines to really support
1896 the dynamic list. Fixes a crash. Affected file is
1897 lib/silccore/silcidcache.c.
1899 * Fixed the LIST command reply to really call LIST command's
1900 pending callbacks. Affected file silcd/command_reply.c.
1902 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Update conn->local_entry->nickname after giving NICK
1905 command. Affected file lib/silcclient/command.c.
1907 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1909 * Added the [pid] option to the silcd configuration file
1911 Affected files: serverconfig.[ch] and silcd.c
1913 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1915 * Save fingerprint in WHOIS command reply in server.
1916 Affected file silcd/command_reply.c.
1918 * Fixed NICK commands pending callback registration.
1919 Affected file lib/silcclient/command.c.
1921 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * Use ++server->cmd_ident when sending commands in server,
1924 instead of random number. Affected file silcd/command.c.
1926 * Fixed GETKEY command reply to call actually GETKEY pending
1927 command callbacks. Affected file silcd/command_reply.c.
1929 * A bit stricter check for nicknames. Check for same nickname
1930 in NICK command also. Affected file silcd/command.c.
1932 * Do not call INFO command everytime client ID changes, only
1933 during first connecting. Affected file lib/silcclient/client.c.
1935 * Set the new nickname only after successful command reply for
1936 NICK command is returned by server. Affected file
1937 lib/silcclient/command.c.
1939 * Remove nicknames from nicklist during server_signoff notify.
1940 Should fix /NAMES bit more. The affected file is
1941 irssi/src/silc/core/silc-channels.c.
1943 * Added `fingerprint' field to the SilcIDListData in the
1944 silcd/idlist.h to hold the fingerprint of the client's
1947 Send the fingerprint of the client's public key in WHOIS
1950 Affected files silcd/command.c, and silcd/idlist.[ch].
1952 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1953 create fingerprint from given data.
1955 * Show the fingerprint of the client's public key in WHOIS.
1956 Affected files irssi/src/module-formats.[ch] and
1957 irssi/src/silc/core/client_ops.c.
1959 * Format the multiple same nicknames also during JOIN and
1960 NICK_CHANGE notifys. Affected file is
1961 lib/silcclient/client_notify.c.
1963 * Do not print error on screen for invalid private message
1964 payload since it can come if someone is sending private
1965 messages with wrong key. Affected file
1966 lib/silccore/silcprivate.c.
1968 * Fixed multiple concurrent /PING crash. Affected file
1969 lib/silcclient/command.c.
1971 * Changed the wrong ID encoding. All IP addresses must be
1972 in MSB first order in encoded format. They were encoded
1973 wrong and was in LSB format. Affected files are
1974 silcd/serverid.c, lib/silcutil/silcutil.c.
1976 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1978 * Call the `connect' client operation through the scheduler
1979 in case of error. Affected file lib/silcclient/client.c.
1981 * Call the `failure' client operation even if the error
1982 occurred locally during a protocol. Affected file is
1983 lib/silcclient/protocol.c.
1985 * Added support of sending LIST command to router from normal
1986 server. This way normal server can get list of all channels
1987 in the network too. Fixed the channel list sending in the
1988 server too. Affected files are silcd/command.c, and
1989 silcd/command_reply.[ch].
1991 * Added silc_server_update_channels_by_server and
1992 silc_server_remove_channels_by_server. They are used during
1993 disconnection of primary router and in backup router protocol.
1994 Affected file silcd/server_util.[ch], silcd/server.c and
1995 silcd/server_backup.c.
1997 * Fixed channel adding to global list in IDENTIFY command
1998 reply in server. Affected file silcd/command_reply.c.
2000 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * If the incoming packet type is REKEY or REKEY_DONE process
2003 that packet always synchronously. Fixes yet another MAC
2004 failed error on slow (dialup) connections. Affected file
2005 lib/silcclient/client.c and silcd/server.c.
2007 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Call check_version SKE callback for initiator too. Affected
2010 file lib/silcske/silcske.c.
2012 * Implemented fix for security hole found in the SKE that was
2013 fixed in the specification few days back; the initiator's
2014 public key is now added to the HASH value computation.
2015 Added backwards support for the old way of doing it too, for
2016 old clients and old servers. Affected file is
2017 lib/silcske/silcske.c.
2019 * Enabled mutual authentication by default in SKE. If initiator
2020 is not providing mutual authentication the responder will
2021 force it. This will provide the proof of posession of the
2022 private key for responder. The affected files are
2023 lib/silcclient/protocol.c and silcd/protocol.c.
2025 * Do not cache anymore the server's public key during SKE.
2026 We do mutual authentication so the proof of posession of
2027 private key is done, and if the server is authenticated in
2028 conn auth protocol with public key we must have the public
2029 key already. Affected file silcd/protocol.c.
2031 * Added new global debug variable: silc_debug_hexdump. If
2032 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2033 file lib/silcutil/silclog.[ch].
2035 * Fixed compilation warning due to char * -> const char *.
2036 Affected files lib/silcutil/silcnet.h, and
2037 lib/silccore/silcauth.[ch].
2039 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Fixed CMODE command when new channel key was created. If
2042 the creation failed the old key was removed. Next time giving
2043 same command would crash the server since the old key was
2044 freed already. Affected file silcd/command.c.
2046 * Fixed the silc_server_announce_get_channels to not crash
2047 on reconnect. Affected file silcd/server.c.
2049 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Added silc_log_set_debug_string function to set a regex
2052 string to match for debug output. Only the function names,
2053 or filenames matching the given debug string is actually
2054 printed. This way it is possible to filter out those debug
2055 strings that user is not interested in.
2057 Fixed a bug in silc_string_regexify.
2059 Affected files lib/silcutil/silclog.[ch], and
2060 lib/silcutil/unix/silcunixutil.c.
2062 * Changed the -d options in both server and Irssi SILC client
2063 to take the debug string as argument. Affected files
2064 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2066 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Added silc_hash_babbleprint to create a Bubble Babble
2069 Encoded fingerprint. The encoding is developed by Antti
2070 Huima (draft-huima-babble-01.txt), and it creates human
2071 readable strings out of binary data. Affected file
2072 lib/silccrypt/silchash.[ch].
2074 * Print the babble print now in addition of fingerprint as well
2075 in Irssi SILC client. Affected files are
2076 irssi/src/fe-common/silc/module-formats.[ch],
2077 irssi/src/fe-common/silc/core/client_ops.c.
2079 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Fixed a security problem found in SKE. The initiator's
2082 public key too is now added to the HASH hash value creation
2083 which is signed by the responder to create the SIGN value.
2084 This will prevent anyone in the middle to lie to the responder
2085 about the initiator's public key. If this is done now, the
2086 man in the middle will get caught. Updated the protocol
2089 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Better installation directory handling. Configure module
2092 paths and other paths automatically to example_silc* files
2093 in doc/. A patch by toma.
2095 * Fixed compiler warning from MPI library, and from SILC RNG.
2098 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2099 It can be configured with ./configure. A patch by toma.
2101 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Find correct make to use in prepare-clean. A patch by
2104 toma. Affected file prepare-clean.
2106 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2108 * Added irssi variables use_auto_addr, auto_bind_ip,
2109 auto_bind_port and auto_public_ip.
2111 * Changed the interface for silc_client_send_key_agreement
2112 in lib/silcclient/silcapi.h
2116 irssi/src/silc/core/silc-core.c
2118 lib/silcclient/silcapi.h
2119 irssi/src/silc/core/silc-channels.c
2120 lib/silcclient/client_keyagr.c
2123 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Added silc_pkcs_public_key_compare to compare two
2126 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2128 * Check that the client who set the founder mode on the
2129 channel is the same client that is giving the founder
2130 mode to itself. It is done by comparing the saved public
2131 key (it is saved even in the authentication is passphrase).

2140 client library. Affected file lib/silcclient/client.c.
2142 * Fixed the silc_client_packet_parse to not to increase
2143 the packet sequence number if the conn->sock and the
2144 current socket connection is not same. This can happen
2145 for example during key agreement when the conn includes
2146 multiple socket connections (listeners). Affected file
2147 lib/silcclient/client.c.
2149 * The sender of the file transfer request now provides also
2150 the pointer (listener) for the key exchange protocol. If
2151 the listener cannot be created then it sends empty key
2152 agreement and lets the receiver provide the listener.
2154 Added `local_ip' and `local_port' arguments to the
2155 silc_client_file_send. If they are provided they are used,
2156 if not then it will attempt to find local IP address, if
2157 not found or bind fails then the remote client will provide
2160 Affected files are lib/silcclient/client_ftp.c and
2161 lib/silcclient/silcapi.h.

2170 of the client's public key (if the proof of posession of the
2171 corresponding private key is verified by the server).
2172 Updated to the protocol specification.
2174 * Added support of receiving the client's public key's
2175 fingerprint in command reply in client library. Affected
2176 file is lib/silcclient/command_reply.c, and
2177 lib/silcclient/idlist.[ch].

2236 preserve the WHOWAS info for the client. Affected file
2237 silcd/server_util.c.
2239 * Fixed SERVER_SIGNOFF notify handling in the server. The
2240 server is now able to process incoming SERVER_SIGNOFF notify
2241 for a server that it doesn't even know about. It will remove
2242 the clients provided in the notify. Affected file
2243 silcd/packet_receive.c.
2245 * Check for partial packet in data queue after every packet that
2246 was found from the queue. Return and wait for more data if
2247 there is partial data in queue. Affected file is

2265 irssi/src/fe-common/silc/module-formats.[ch].
2267 * Wrote a help file for FILE command.
2269 * Added silc_rng_global_get_byte_fast to get not-so-secure
2270 random data as fast as possible. Random data is read from
2271 /dev/urandom if available and from the SILC RNG if not
2272 available. It is used in padding generation. Affected file
2273 lib/silccrypt/silcrng.[ch].
2275 * All packets in client library are now processed synchronously.
2276 Optimized packet processing a lot. Affected file
2277 lib/silcclient/client.c.

2288 * Assure that silc_client_notify_by_server_resolve does not
2289 resolve the client information multiple times. If it cannot
2290 be found by the first it cannot be found at all. Affected
2291 file lib/silcclient/client_notify.c.
2293 * Fixed WHOWAS command reply calling. Affected file
2294 lib/silcclient/command_reply.c.
2296 * Removed all references to silc_idlist_get_client from the
2297 Irssi SILC client since that call is internal call used by
2298 the library. The Irssi SILC client will use now client
2299 retrieval functions found in silcapi.h.
2301 * Fixed a bug in resolving nickname info before sending
2302 private message. It used freed memory. Affected file
2303 irssi/src/silc/core/silc-servers.c.

2325 Affected file lib/silcutil/silcnet.[ch].
2327 * If key exchange or rekey protocol is active for a connection
2328 parse all packets syncronously since there might be packets
2329 in packet queue that we are not able to process without first
2330 processing packets before them. Affected file silcd/server,
2331 lib/silcclient/client.c.
2333 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2334 whether library should continue processing the packet.
2335 Affected file lib/silccore/silcpacket.h.

2408 * Call the silc_server_udpate_servers_by_server in the
2409 primary router that comes back online in the backup resuming
2410 protocol. Otherwise it routes packets wrong. Affected file
2411 silcd/server_util.[ch], silcd/server_backup.c.
2413 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2415 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2416 lib/silcutil/silcbuffmt.[ch].

2419 length. Affected file lib/silccore/silcpacket.[ch].
2421 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2422 length for maximum padding up to 128 bytes). Affected
2423 file lib/silccore/silcpacket.h.
2425 * Removed all backwards support for old 0.5.x MAC thingies.
2426 The SILC packet header change makes it impossible to be
2427 backwards compatible.
2429 * Send the ENDING packet with timeout in the backup resuming
2430 protocol. This is to assure that all routers has connected
2431 to the primary router. Affected file silcd/server_backup.c.
2433 * Changed the RNG to take the first IV from random data. It
2434 used to take it from zero actually. Changed the RNG also

2441 (the packet length) encrypted. Affected files aroung the
2442 code tree, lib/silccore/silcpacket.[ch]. Removed the
2443 SilcPacketCheckDecrypt callback. It is not needed anymore
2444 since the silc_packet_receive_process will determine now
2445 whether the packet is normal or special.

2458 * Allow backup router to announce servers. All servers
2459 announced by backup router are added to the global list
2460 automatically. Update hte server's socket to our primary
2461 router also when backup router announces a server.
2462 Affected file silcd/packet_receive.c.
2464 * Do not update the client->router in the function
2465 silc_server_udpate_clients_by_server if the client is on
2466 global list. We might fail to find any specific server
2467 for locally connected clients and local cell clients. They
2468 should still use the `from' and not `to' as client->router.
2469 This fixes backup router resuming protocol. Affected file
2470 silcd/server_util.c.
2472 * Decrease channel statistics count only if the channel
2473 deletion worked. Affected files are silcd/server.c and
2474 silcd/server_util.c.
2476 * Added silc_server_update_servers_by_server to update origin
2477 of all server entries. Used during backup router protocol.

2494 to the router it came from. Affected file is
2495 silcd/packet_send.c. Fixed memory leak too.
2497 * Announce informations for incoming router connection, but
2498 only after checking if it is replaced by backup router.
2499 Affected file silcd/packet_receive.c.
2501 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2513 Affected file silcd/packet_send.c.
2515 * Changed the SFTP Filesystem interface. Changed the
2516 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2517 the filesystem operation function. The SilcSFTPFilesystem
2518 is now a context that is allocated by all filesystem allocation
2519 functions and it already includes the operations structure
2520 and filesystem specific context. It is given as argument
2521 now to the silc_sftp_server_start. This made the interface
2522 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2523 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2525 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Changed the backup router adding and getting interfaces
2528 in the server. The router that will be replaced by the

2590 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2591 in the server to indicate disabled entry. All data read
2592 from the connection will be ignored and no data is sent
2593 for entry that is disabled. Affected files are
2594 silcd/idlist.h, silcd/server.c.

2645 new packet type SILC_PACKET_FTP and defined File Transfer
2646 Payload. The mandatory file transfer protocol is SFTP
2647 (SSH File Transfer Protocol). Affected file in addition
2648 of the internet draft is lib/silccore/silcpacket.h.
2650 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2651 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2652 is used as part of backup router protocol when the primary
2653 router of the cell is back online and wishes to resume
2654 the position as primary router.
2656 * Redefined the MAC generation keys in the protocol. The
2657 same key is not used anymore in both direction. Both
2658 direction will now use different keys for sending and
2659 receiving. This fixes a potential security flaw. This
2660 change causes incompatibilities in the protocol.
2662 * Redefined also the MAC computation from the packet.
2663 An packet sequence number is now added to the MAC
2664 computation. This prevents possible replay attacks against
2665 the protocol. This change too causes incompatibilities
2668 Added `sequence' field to the SilcPacketContext to hold
2669 the current sequence number for the packet.
2671 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Added `created' field to the SilcIDListData in the file
2674 silcd/idlist.h to indicate the time when the entry was
2677 * Added `created' field to the SilcChannelEntry too. Affected
2678 file silcd/idlist.h.
2680 * Added `creation_time' aguments to all the announcement functions
2681 in the server. If it is provided then only the entries that
2682 was created after the provided time frame are actually
2683 announced. Affected file silcd/server.[ch].
2685 * The protocol says that the Channel ID's IP address must be
2686 based on the router's IP address. Added check for this in
2687 the silc_server_new_channel when processing incoming New Channel
2688 Payload. Affected file silcd/packet_receive.c.
2690 * Print out the correct version with --version in SILC client.
2691 Affected file irssi/src/silc/core/silc-core.c.
2693 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Fixed WHOWAS command to check for completnes of the client
2696 entry always, not just when the command is coming from client.
2697 Affected file silcd/command.c.
2699 * Added new function silc_server_packet_queue_purge to purge the
2700 outgoing data queue to the network. After the function returns
2701 it is guaranteed that the outgoing packet queue is empty.
2702 Affected file silcd/packet_send.[ch].
2704 * Purge the outgoing packet queue in the rekey protocol's final
2705 callback to assure that all rekey packets go to the network
2706 before quitting the protocol. Affected file silcd/server.c.
2708 * Added silc_client_packet_queue_parse as similar function as
2709 in server to the client library. The affected file is
2710 lib/silcclient/client.c.
2712 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Splitted silcd/server.c and created silcd/server_util.[ch]
2715 for utility functions.
2717 * Added new socket flag SILC_SF_DISABLED to indicate that the
2718 connection is open but nothing can be sent to or received from
2719 the connection. Affected file lib/silcutil/silsockconn.[ch].
2720 The checking for disabled socket is checked in the low level
2721 silc_socket_write and silc_socket_read functions.
2723 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Allow only nicknames and channel names that fits into the
2726 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2728 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2730 * When processing JOIN command reply in server check that if
2731 the channel exists in our global list we'll move it the local
2732 list. Affected file silcd/command_reply.c.
2734 * Fixed the check whether client is joined on the channel already
2735 in JOIN command. Affected file lib/silcclient/command.c.
2737 * Fixed the JOIN command reply to check whether the channel
2738 already exists. Affected file lib/silcclient/command_reply.c.
2740 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Added silc_ske_status_string to map the SKE error numbers
2743 to readable strings. The affected files are
2744 lib/silcske/silcske[_status].[ch].
2746 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2748 * Do not show the private channels on the WHOIS channel list
2749 as it is not allowed by the protocol. The affected file is
2752 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Assure that the packet length digged from the actual packet
2755 is something sensible in the silc_packet_decrypt_rest_special
2756 in lib/silccrypt/silcpacket.c.
2758 * Free and NULL the allocated pointer in silc_hmac_alloc if
2759 the HMAC allocation fails. The affected file is
2760 lib/silccrypt/silchmac.c.
2762 * Print the selected security properties to the log files in
2763 the server. Affected file silcd/protocol.c.
2765 * Add SKE's reference counter even if calling the completion
2766 callback manually. Otherwise it goes negative, although it
2767 does not cause any problems. The affected file is
2768 lib/silcske/silcske.c.
2770 * Remove the client entry with short timeout after giving the
2771 KILL command. Affected file lib/silcclient/command.c.
2773 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2774 case all found clients are already disconnected (WHOWAS would
2775 found them) in the server. Affected file silcd/command.c.
2777 * Update the last_receive (time of last data received) to be
2778 updated only when received private or channel message so that
2779 the idle time showed in WHOIS makes more sense.
2781 * Added boolean field `valid' in to the SilcClientEntry in the
2782 client library to indicate whether the entry is valid or not.
2783 This fixes the nickname change bug on channel when changing
2784 the nickname to be same than the old (like nick to Nick) the
2785 nickname formatter doesn't set the new nick anymore to Nick@host.
2786 Affected file lib/silcclient/idlist.[ch].
2788 * Now actually fixed the nickname changing on disconnection.
2789 Added new function silc_change_nick to the Irssi SILC Client.
2790 Affected file irssi/src/silc/core/client_ops.c,
2791 irssi/src/silc/core/silc-nicklist.[ch].
2793 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Check that the public key exists in the GETKEY command before
2796 trying to encode it. Affected file silcd/command.c.
2798 * Print some notifications on received public keys with GETKEY
2799 command in the Irssi SILC Client. Affected files are
2800 irssi/src/fe-common/silc/module-formats.[ch],
2801 irssi/src/silc/core/client_ops.c.
2803 * Use IDENTIFY command to resolve the server information in the
2804 GETKEY command instead of INFO command. Affected file
2805 lib/silcclient/command.c.
2807 * All command reply functions in the client library now calls
2808 the pending command reply callbacks even if an error has
2809 occurred. The server has done this a long time and now it was
2810 time to move the client library to this as well. Now all
2811 errors can be delivered back to the pending command reply
2812 callbacks if necessary. Affected files are
2813 lib/silcclient/command[_reply].[ch].
2815 * Change the nickname on disconnection back to the username
2816 because in reconnect the server will enforce it to it anyway.
2817 Affected file irssi/src/silc/core/silc-servers.c.
2819 * Fixed a config file parsing bug in the Irssi SILC client.
2820 Affected file irssi/src/silc/core/clientconfig.c.
2822 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2824 * When printing the channel mode on JOIN, verify that the
2825 channel key and channel's HMAC are valid. Affected file
2826 irssi/src/silc/core/client_ops.c.
2828 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2830 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2831 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2832 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2834 * Removed channel key rekey task deleting from the function
2835 silc_server_save_channel_key. Affected file silcd/server.c.
2836 Added explicit timeout task context instead that is used to
2837 delete the task if we are registering a new task before the
2838 new task has elapsed.
2840 * When channel key rekey occurs the client library now saves
2841 the old channel key for a short period of time (10 seconds) and
2842 is able to use it in case some is still sending channel
2843 messages encrypted with the old key after the rekey. Affected
2844 file lib/silcclient/[idlist.h|client_channel.c].
2846 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Added check to the silc_server_new_id_real to not accept
2849 new ID if it is the sender's own ID. Affected file is
2850 silcd/packet_receive.c.
2852 * Assure that we do not announce ourself or the one we've
2853 sending our announcements when we're router and are announcing
2854 servers to our primary router. Affected file silcd/server.c.
2856 * Fixed silc_server_command_identify_check_client to assemble
2857 correct WHOIS packet. It send corrupted WHOIS packet and
2858 caused problem with router to router connections. Affected
2859 file silcd/command.c.
2861 Fixed also silc_server_command_whois_check the same way
2862 as for the IDENTIFY command.
2864 * Added new SilcIDListStatus to the server in the SilcIDListData
2865 structure. The status now includes the current status of
2866 the entry (like registered, resolved etc.). Affected file
2867 silcd/idlist.[ch]. Defined a bunch of different status types
2868 as well. This replaced the old boolean registered field as well.
2870 Added resolve_cmd_ident field to the SilcClientEntry structure
2871 too so that if the entry is for example being resolved so
2872 another command may attach to the same pending command reply
2873 without requiring to resolve the same entry again. This concept
2874 should optimize the WHOIS and the IDENTIFY resolving under
2875 heavy load by taking away unnecessary resolving for entries
2876 that are being resolved already.
2878 Added support for adding multiple pending commands for one
2879 command idenfier. Affected file silcd/command[_reply].[ch].
2881 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2882 before deleting the data. Otherwise the hash table will have
2883 freed data in comparison functions. Affected file is
2884 silcd/command_reply.c.
2886 * Fixed silc_idlist_replace_client_id to add the new entry to
2887 the cache with NULL nickname. Otherwise there will be invalid
2888 memory as the nickname after the nickname is freed. Affected
2889 file silcd/packet_receive.c.
2891 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2892 saved into wrong slots because the previous number of entries
2893 was not taken into account. Affected file silcd/idlist.c.
2894 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2896 * If we are router and we receive JOIN notify to a channel that
2897 does not have any users then notified client is marked as the
2898 channel founder, as it is it. The affected file is
2899 silcd/packet_receive.c
2901 * Added to the extended hash table API's table_del_*ext functions
2902 the destructor as argument too, so that the caller can decide
2903 which destructor to use or whether to use destructor at all.
2904 Affected file lib/silcutil/silchashtable.[ch].
2906 * Fixed ID Cache purging. It actually deleted the entries from
2907 the hash table after the data was freed. The hash table ended
2908 up comparing freed memory. The affected file is
2909 lib/silccore/silcidcache.c.
2911 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Fixed Irssi SILC client's KILL command's HELP syntax.
2915 * The USERS command now resolves the detailed user information
2916 if the userinfo field is missing. Affected file is
2917 lib/silcclient/command_reply.c.
2919 * Do not print error in silc_file_read if the read file does
2920 not exist. Just silently return NULL. Affected file is
2921 lib/silcutil/silcutil.c.
2923 * Fixed the silc_log_output to not wine about NULL filename
2924 and to not create some bogus " " filename. Affected file is
2925 lib/silcutil/silclog.c.
2927 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Fixed various printing bugs on the user interface in the
2930 Irssi SILC Client. Minor changes that were forgotten from
2933 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Fixed the configure.in.pre and the compilation and distribution
2936 environment to support the new autoconf 2.52. That version is
2937 now required to compile the CVS trunk.
2939 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2942 to generally parse user@fqdn format strings. Affected file
2943 lib/silcutil/silcutil.c.
2945 * Added nickname_format and nickname_force_format fields to the
2946 SilcClientParams structure. The first one defines the format
2947 for the nicknames that the library will enforce if the receives
2948 multiple same nicknames. The second one is boolean value and
2949 can be used to force the library to always enforce the format
2950 to the nicknames regardles whether there are multiple nicknames
2951 or not. This configurable formatting was employed to flexibly
2952 support accessing multiple nicknames from the user interface.
2953 The userinterface can now set the nicknames to what ever format
2954 they prefer. Affected file lib/silcclient/silcapi.h.
2956 Added function silc_client_nickname_format to the file
2957 lib/silcclient/idlist.c. It performs the nickname formatting.
2959 Added new field `hostname´ to the SilcClientEntry context.
2960 It holds the hostname of the client. Affected file is
2961 lib/silcclient/idlist.h.
2963 * Irssi SILC Client sets the nicknames in nick@hostn format.
2964 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2965 irssi/src/silc/core/silc-core.c.
2967 The WHOIS printing now also shows both the real nickname and
2968 the formatted nickname so that user knows how to access the
2969 user if there are multiple same nicknames cached. Affected
2970 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2971 printing formatting too to take the hostname now as a separate
2972 argument. The Affected file is
2973 irssi/src/fe-common/silc/modules-formats.[ch].
2975 * Changed the silc_client_get_clients_local to accept the formatted
2976 nickname as argument. It accepts the real nickname too but the
2977 formatted nickname can be used to find the true entry from
2978 multiple entries. Affected file lib/silcclient/silcapi.h and
2979 lib/silcclient/idlist.c.
2981 * Added nickname_format_parse field to the SilcClientParams.
2982 It is a callback function provided by the application to parse
2983 the nickname out of the formatted nickname string. The library
2984 calls it to get the nickname from the formatted string. Since
2985 the application generally knows better the format of the nickname
2986 string it parses it instead of the library, even though library
2987 encodes the formatted string. If the callback function is not
2988 provided then the library will use the string as is. The
2989 affected file is lib/silcclient/silcapi.h.
2991 * All the nickname strings passed to the client library in
2992 commands are now expected to be formatted nickname strings.
2993 If the command does not support the formatted nickname string
2994 it will assume that the sent string is the actual nickname.
2995 Affected file lib/silcclient/command.c.
2997 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Added public key authentication support to OPER and SILCOPER
3000 commands in the client library. Affected file is
3001 lib/silcclient/command.c.
3003 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * Changed the get_auth_methdod client operation to be asynchronous.
3006 It can be async if the application resolves the authentication
3007 method from the server during the negotiation. Added new
3008 SilcGetAuthMeth completion callback that the application will
3009 call after resolving the authentication method.
3011 Added function silc_client_request_authentication_method that
3012 the application can use to resolve the authentication method
3013 from the server. Added also SilcConnectionAuthRequest callback
3014 that the library will call after the server has replied. The
3015 application can call this function if it does not know the
3016 current authentication method.
3018 Affected files are lib/silcclient/client.c and
3019 lib/silcclient/silcapi.h.
3021 * The Irssi SILC client now automatically resolves the authentication
3022 method incase any configuration information is not present (and
3023 currently there never is). The affected file is
3024 irssi/src/silc/core/client_ops.c.
3026 * Fixed public key authentication from the client library.
3027 Affected file lib/silcclient/protocol.c. Changed also the
3028 protocol specification about the public key authentication in
3029 the connection authentication protocol. The actual data to be
3030 signed is now computed with a hash function before signing.
3032 * Fixed the public key authentication from the server as well.
3033 Affected file silcd/protocol.c.
3035 * Removed the mlock()'s from the memory allocation routines.
3036 Affected file lib/silcutil/silcmemory.c. The ./configure does
3037 not check anymore for the mlock(). Affected file is
3040 * Fixed USERS command in server to allow the execution of the
3041 command for private and secret channels if the client sending
3042 the command is on the channel. Affected file silcd/command.c.
3044 * Fixed silc_client_get_clients_local to return the clients
3045 count correctly. It could return wrong value. Affected file
3046 lib/silcclient/idlist.c.
3048 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3051 types. The assembler optimizations seemed not to like 64-bit
3052 data types. The assmebler optimizations thus are now enabled
3053 also for BSD systems as opposed to only enable them for Linux.
3055 * Do not check for threads at all on BSD systems. Affected
3056 file configure.in.pre.
3058 * Removed -n and -h options from the Irssi SILC Client since
3059 they are not used in silc.
3061 * Fixed the prime generation to assure that the first digit
3062 of the generated random number is not zero since our conversion
3063 routines does not like number strings that starts with zero
3064 digit. If zero digit is seen the random number is regenerated.
3065 This caused some corrupted RSA keys when the zero first digit
3066 was met. Affected file lib/silcmath/silcprimegen.c.
3068 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Fixed WIN32 configuration in the ./configure script.
3071 Fixed to include xti.h on environments that has it.
3072 Patches by Carsten Ilchmann and andrew.
3074 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3076 * Changed the silc_id_create_client_id to be collision
3077 resistant. It is now assured that there cannot be created
3078 two same client ID's. I suspect that some weird bugs in
3079 the server were actually caused by duplicate Client IDs.
3080 Affected file silcd/serverid.[ch]. A router receiving
3081 new ID now also assures and informs the sending server
3082 if the ID caused collision.
3084 * Changed the silc_id_create_channel_id to also assure that
3085 there are no collisions.
3087 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Statement about ignoring the Mutual Authentication flag when
3090 performing rekey with PFS was a bit misleading. It is ignored
3091 if it was set in the initial negotiation, it cannot be even
3092 set in the rekey. Fixed in the ke-auth draft. Started the
3093 new versions of the protocol drafts in the doc/.
3095 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Fixed a bug in silc_client_command_identify_save when saving
3098 new channel information. The channel name was no duplicated
3099 and caused crash on exit. Affected file is
3100 lib/silcclient/command_reply.c.
3102 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Fixed the getkey command handling in the server. Send just
3105 empty OK reply to the sender if the key could not be fetched
3106 (but everything else was ok, like the key just was not available).
3107 Changed the public key parameter to optional in the protocol
3108 specs so that empty OK reply can be sent. Affected file
3111 Added a message to Irssi SILC client to tell to user if the
3112 server did not return a public key.
3114 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Fixed a channel key regeneration bug. It registered new
3117 timeout tasks exponentially until all system resources were
3118 used. Affected file silcd/server.c.
3120 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Added the SILC Document generator to the scripts/silcdoc.
3123 It can be used to generate the Toolkit Reference Manual out
3124 of the source tree. Internally it will also use the RoboDoc
3125 generator now imported in util/robodoc.
3127 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Added couple of return's in rekey protocol if error orccurred
3130 during the protocol. The execution must be terminated.
3131 Affected file silcd/protocol.c. Also, terminate the protocol
3132 always with timeout.
3134 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * The client's Client ID was created initally from the wrong
3137 nickname (it could have been in format nick@host) in the
3138 silc_server_new_client. Affected file silcd/packet_receive.c
3140 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * Added some SILC_LOG_ERROR's to various error conditions
3143 if client could not be added to ID cache. Affected files
3144 silcd/packet_receive.c and silcd/server.c.
3146 * When client's sock->user_data is freed, NULL also the
3147 client->router and client->connection pointers. Added check
3148 for these pointers being NULL to various places around the
3149 code. Affected file silcd/server.c.
3151 * Added client->data.registered == TRUE checks to various
3152 places around the code to assure that unregistered client's
3153 are not handled when it is not allowed. Affected file
3156 * Added `bool registered' fields to all
3157 silc_idlist_[server|client]_get_* routines to indicate whether
3158 the fetched client needs to be registered or not. Affected
3159 file silcd/idlist.[ch].
3161 * Add your own entry as registered to the ID cache in the
3162 server. Affected file server.c.
3164 * Fixed a bug in silc_server_new_server. The SilcServer was
3165 set as the new server's context instead of SilcServerEntry.
3166 This naturally caused some weird bugs.
3168 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Do not delete the channel rekey task when adding it
3171 for in silc_server_create_channel_key.
3173 * Changed the silc_server_create_channel_key to return
3174 TRUE or FALSE to indicate the success of the channel key
3177 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Fixed MSVC++ project files and added missing files to

3188 * Fixed buffer overflow from Irssi SILC Client. Affected
3189 file irssi/src/fe-common/core/themes.c.
3191 * Fixed double free in client library in the file
3192 lib/silcclient/client.c when disconnecting from server.
3194 * Applied double free patch from cras to Irssi SILC client.
3195 Affected files irssi/src/core/[modules/expandos].c
3197 * Fixed the disconnection handling to Irssi SILC Client.
3198 The application must call silc_client_close_connection
3199 in ops->connect client operation in case of failure of
3200 the connection. Affected file is
3201 irssi/src/silc/core/client_ops.c.
3203 * Do not set sock->protocol to NULL in the function
3204 silc_client_close_connection after executing the protocol's
3205 final callback since the sock might not be valid anymore.
3206 Affected file lib/silcclient/client.c.
3208 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3210 * Do not enable SILC_THREADS if the linking with libpthread
3211 did not happen. Affected file configure.in.pre.
3213 * Added notion to protocol specification that server must
3214 verify the sent authentication payload with CMODE when
3215 setting the channel founder key. Implemented it to the
3216 server. Affected file silcd/command.c.
3218 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Added _EXTRA_DIST SILC distribution variable to the
3221 distributions file. It is used to conditionally add extra
3222 files or directories to the specific distribution. Affected
3223 files ./prepare, Makefile.am.pre and distributions.
3225 Removed the `_' from the start of the distribution names.
3228 * Added README.WIN32 for instructions to compile the Toolkit
3231 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Fixed a double free in disconnection in the server. Affected
3234 file is silcd/server.c.
3236 * Fixed the lib/silcske/groups.c to work now also with GMP
3237 MP library. The string conversion did not work when using
3238 specific base and the base is indicated in the string as well.
3240 * Created win32/ directory which now includes MSVC++ specific
3241 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3242 It will appear only in the toolkit distribution
3244 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3246 * Changed the key material distribution function in case when
3247 the hash output is too short. The data is now concatenated
3248 a bit differently than it used to. Made the change to the
3249 SKE protocol specification.
3251 * Added better GMP detection to configure.in.pre. A patch
3254 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3256 * Fixed a minor bug in SKE that might cause some problem on
3257 some platforms. Affected file lib/silcske/silcske.c.
3259 * Added the cookie checking for initiator in the SKE. It checks
3260 that the responder returns the sent cookie unmodified. The
3261 affected file is lib/silcske/silcske.c. Added new SKE
3262 error type INVALID_COOKIE that can be sent during the
3263 negotiation. Fixed some memory leaks as well.
3265 * Added the "invalid cookie" error message to Irssi SILC client's
3268 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Added `task_max' field to the SilcClientParams to indicate
3271 the maximum tasks the scheduler can handle. If set to zero,
3272 default values are used. Affected file lib/silcclient/silcapi.h.
3274 * Fixed memory leaks in silc_client_close_connection. Affected
3275 file lib/silcclient/client.c.
3277 * Added silc_client_del_client_entry to client library to free
3278 all memory of given client entry. Affected file is
3279 lib/silcclient/idlist.[ch].
3281 * Added new functions silc_client_del_channel and
3282 silc_client_del_server to delete channel and server entries.
3283 Affected file lib/silcclient/[silcapi.h/idlist.c].
3285 * Removed silc_client_del_client_by_id from silcapi.h.
3287 * Fixed the INFO command to return the server's own info
3288 correctly when querying by Server ID. Affected file is
3291 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Removed the non-blocking settings in WIN32 code in the
3294 silc_sock_[read/write] and added SleepEx instead. Affected
3295 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3296 of input data is now checked with FIONREAD and ioctlsocket.
3298 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3300 * Call silc_schedule_task_del_by_context in the
3301 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3302 Affected file lib/silccore/silcprotocol.c.
3304 * Call silc_protocol_cancel for active protocols in the
3305 silc_server_close_connection if the funtion
3306 silc_server_free_sock_user_data has not been called.
3307 Affected file silcd/server.c.
3309 * Generic tasks cannot be deleted using the del_by_fd
3310 task deleting function since generic tasks does not match
3311 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3313 * Added a notion to SILCOPER help file that the SILCOPER works
3314 only on router server, not on normal server.
3316 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Added for WIN32 support for the new scheduler as well.
3319 Affected file lib/silcutil/win32/silcwin32schedule.c.
3321 * Fixed the SHA1 implementation to work on various platforms.
3323 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3326 API. It is part of the scheduler now. Everything else is
3327 as previously but some functions has changed their names.
3328 Checkout the lib/silcutil/silcschedule.h for the interface.
3329 Updated all applications to use the new interface. Affected
3330 files are lib/silcutil/silcschedule.[ch].
3332 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3334 * Found a bug in the SKE implementation. The HASH value,
3335 specified by the protocol, was not computed correctly. The
3336 public key of the responder was not added to the computation
3337 even though it is mandatory. Affected file lib/silcske/silcske.c.
3338 This unfortunately causes incompatibilities with older
3339 clients and servers.
3341 * Added WIN32 specific network init and uninit functions:
3342 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3343 the Winsock2. Affected file lib/silcutil/silcnet.h and
3344 lib/silcutil/win32/silcwin32net.c.
3346 * Set the socket always to nonblocking mode on WIN32 after
3347 reading data or writing data. Affected file is
3348 lib/silcutil/win32/silcwin32sockconn.c.
3350 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Fixed various compilation problems under WIN32. Affected
3353 files lib/silcutil/win32/silcwin32thread.c and
3354 lib/silcutil/win32/silcwin32schedule.c.
3356 * Removed all _internal.h #includes from public header
3357 files. Internal headers must never be included from
3360 Removed also the lib/silcske/payload_internal.h file.
3362 * All include files that may be needed (public and some others
3363 included by the public headers) by application developers are
3364 now copied to the ./includes directory. It does not copy any
3365 internal headers. Affected file Makefile.defines.pre and all
3366 Makefile.am's under lib/ and subdirs.
3368 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3370 * Do not change the ~/.silc directory's permissions automatically.
3371 Affected file irssi/src/silc/core/clientutil.c.
3373 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Do not cancel the protocol in silc_server_close_connection
3376 it might cause recursion. Now cancelled in the function
3377 silc_server_free_sock_user_data. Affected file silcd/server.c.
3379 * Fixed the silc_server_remove_clients_by_server to regenerate
3380 the channel keys correctly finally. Added also new function
3381 silc_server_remove_clients_channels to actually do it.
3382 Affected file silcd/server.c.
3384 * Fixed the silc_server_new_channel to not crash by giving
3385 wrong router to the new channel. Affected file is
3386 silcd/packet_receive.c.
3388 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3391 which is given as argument to the silc_client_alloc now.
3392 It can be used to configure the client and set various parameters
3393 that affect the function of the client.
3395 * The USERS command in server did not check whether the channel
3396 is private or secret. Affected file silcd/command.c.
3398 * Added new argument to the USERS command in protocol specification.
3399 The USERS command now can take the channel name as argument
3400 as well. Added support for this in client and server and
3401 updated the protocol specs.
3403 * Completed the GETKEY command in client. It can be now used
3404 to fetch also servers public key not only some clients.
3405 Affected files lib/silcclient/command[_reply].c.
3407 * Added silc_client_get_server to return server entry by the
3408 server name. Affected files lib/silcclient/silcapi.h and
3411 * Redefined the IDENTIFY command in protocol specification to be
3412 more generic. It now can be used to query information about
3413 any entity in the SILC Network, including clients, servers and
3414 channels. The query may be based either the entity's name
3415 or the ID. Added support for this in both client and server.
3417 Affected files silcd/command.c and lib/silcclient/command.c
3418 and command_reply.c.
3420 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3421 the _from_client and _from_server functions. Affected file
3424 * Added silc_client_get_channel_by_id_resolve to the file
3425 lib/silcclient/silcapi.h to resolve channel information by
3426 its ID. Added also silc_client_get_channel_by_id that
3427 does not resolve it from the server.
3429 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Added SilcServerEntry context into the client library
3432 to represent one server. The INFO command now allocates
3433 these to save the resolved server info. For now on the
3434 client library will also keep information about servers,
3435 connected and resolved with INFO.
3437 The INFO command now allocates the SilcServerEntry context
3438 and saves the server info there. The COMMAND_REPLY in
3439 the INFO now returns the parameters to application in
3440 same order as defined in the protocol specification.
3442 The entries are cached in the client->server_cache.
3444 * The INFO command is now issued after received the Client ID
3445 from the server. Affected file lib/silcclient/client.c.
3447 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3448 to the application as the mode changer might be server.
3449 It is guaranteed that NULL is not returned anymore to the
3450 application. Affected file lib/silcclient/client_notify.c.
3452 The ID Type is now also passed to the application so that
3453 it can check whether the returned entry is SilcClientEntry
3456 Added new function silc_client_get_server_by_id to return
3457 the server entry by ID. Affected files are the
3458 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3460 * Do not create the channel in the Irssi SILC Client when issuing
3461 the JOIN command but when received the sucessful JOIN command
3462 reply. Otherwise the channel might get created even though we
3463 could not join it. The Affected file is
3464 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3466 * Fixed a channel joining bug in router. The router must also
3467 check the channel modes, invite and ban lists etc. when serving
3468 the JOIN command sent by normal server. Affected file is
3469 silcd/command.c. The router now resolves the client's
3470 information from the server who sent the JOIN command if it
3471 does not know it, and processes the JOIN command only after
3474 * Changed the SilcCommandCb to take new argument; void *context2.
3475 Affected file lib/silccore/silccommand.h
3477 The second argument in the command callbacks in the server now
3478 includes the SilcServerCommandReplyContext if the command was
3479 called as pending command callback from the command reply.
3480 Otherwise it is NULL. When called as pending the status of the
3481 command reply will be checked and if it was erronous the
3482 error will be sent to the original sender of the command.
3483 This way the client always receives the error messages even
3484 though the server was actually the one who received the error
3485 when it resent the command to router, for example. Affected
3486 files silcd/command[_reply].[ch].
3488 * Fixed sending WHOWAS command's error message to client if
3489 the requested client could not be found. It was missing.
3492 * Changed the CMODE and CUMODE commands reply arguments in the
3493 protocol specification. The Channel ID is now sent in both
3494 of the commands to identify the channel. Implemented this
3495 new feature to the client and server. Affected files
3496 lib/silcclient/command_reply.c and silcd/command.c.
3498 * Made better checks for invite and ban lists in the JOIN
3499 command in server. Affected file silcd/command.c.
3501 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3503 * The server now performs the incoming host IP/DNS lookup
3504 using the silc_socket_host_lookup and thus does not block
3505 the server anymore. Affected file silcd/server.c.
3507 * Completed the multi-thread support for SILC Scheduler in
3508 the lib/silcutil/silcschedule.c.
3510 * Fixed the configure.in.pre to detect the pthread correctly
3513 * Fixed a deadlock in silc_task_queue_wakeup in the file
3514 lib/silcutil/silctask.c.
3516 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Added new function silc_schedule_wakeup that is used in
3519 multi-threaded environment to wakeup the main thread's
3520 schduler. It needs to be used when a thread adds a new task
3521 or removes a task from task queues. After waking up, the
3522 scheduler will detect the task queue changes. If threads
3523 support is not compiled in this function has no effect.
3524 Implemented the wakeup mechanism to both Unix and WIN32
3525 systems. Affected files are lib/silcutil/silcschedule.[ch],
3526 lib/silcutil/unix/silcunixschedule.c and the
3527 lib/silcutil/win32/silcwin32schedule.c.
3529 * Added new function silc_task_queue_wakeup to wakeup the
3530 scheduler by the specified task queue. Affected file
3531 lib/silcutil/silctask.[ch].
3533 * The silc_socket_host_lookup_start now wakes up the scheduler
3534 after adding the timeout task. Affected file is
3535 lib/silcutil/silcsockconn.c.
3537 * The silc_socket_host_lookup is synchronous now if the threads
3538 support is not compiled in. However, the callback is still
3539 called asyncronously through the scheduler, anyway. Affected
3540 file lib/silcutil/silcsockconn.c.
3542 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * Added new function silc_socket_host_lookup to perform
3545 asynchronous IP and FQDN lookups for the socket connection.
3546 Affected files lib/silcutil/silcsockconn.[ch].
3548 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3550 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3551 that may or may not compile the mutex support in.
3553 Changed the silc_mutex_alloc interface. It allocates the
3554 mutex now to the sent pointer and returns TRUE or FALSE.
3556 Affected file lib/silcutil/silcmutex.h.
3558 * Wrote the SILC Task Queue interface to support multi-threads.
3559 Affected file lib/silcutil/silctask.[ch].
3561 * Wrote the SILC Scheduler to support multi-threads. Affected
3562 file lib/silcutil/silcschedule.c.
3564 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3567 in lib/silcutil/win32/.
3569 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Defined SILC Mutex API and SILC Thread API and implemented
3572 them for Unix. Affected files are
3573 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3574 lib/silcutil/unix/silcunixmutex.c and
3575 lib/silcutil/unix/silcunixthread.c.
3577 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Fixed the silc_server_remove_clients_by_server's channel
3580 key re-generation. The hash table handling was incorrect
3581 and would not work with many channels. Affected file is
3584 * Fixed some memory leaks around the server code.
3586 * Rewrote the silc_server_get_users_on_channel to support IPv6
3587 based Client ID's. Affected file silcd/server.c.
3589 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3590 specification. However, a separate document must be written
3591 to define the detailed signing procedure and the payload
3592 associated with the flag. Defined the flag to the
3593 lib/silccore/silcchannel.h as well.
3595 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Changed the dynamic tables to static size tables in the
3598 lib/silccrypt/silchmac.c.
3600 * Removed GCC dependencies from the code. A patch by cras.
3602 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3604 * Do not show the error "Error receiving packet bla bla"
3605 in server if it really was not an error (-2 means that reading
3606 is pending). Affected file silcd/server.c.
3608 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Fixed a possible crash in silc_server_remove_clients_by_server
3611 in silcd/server.c. Fixed there also some memory leaks.
3613 * Fixed the silc_idlist_replace_client_id. It could replace
3614 wrong key in the hash table. Affected file silcd/idlist.c.
3616 * Do not check whether there are global users on the channel
3617 if the channel->global_users is FALSE. Affected functions
3618 silc_server_remove_from_one_channel and
3619 silc_server_remove_from_channels in silcd/server.c. Also,
3620 do not check if the removed client is local as we can be
3621 sure that global client was not removed from the channel
3622 and checking for global users is not needed.
3624 * The silc_server_remove_clients_by_server now re-generates
3625 the channel keys correctly for those channels that had
3626 clients removed from them. Affected file silcd/server.c.
3628 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * Found the reason of random crashes in the server. We weren't
3631 ignoring the SIGPIPE signal (which can be sent in write())
3632 and it crashed the server. Affected file silcd/silcd.c.
3634 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3636 * Assure that sock->user_data is not NULL in the function
3637 silc_server_packet_send in silcd/packet_send.c.
3639 * Disconnect the remote connection if it could not be added
3640 to any ID lists in the server. The affected file is
3643 * Check in silc_server_packet_send[_real/dest] that the
3644 socket is not disconnecting and ignore the data if it is.
3645 Affected file silcd/packet_send.c.
3647 * Define inline to __inline on native WIN32 compilation.
3648 Affected file includes/silcwin32.h.
3650 * Added some explicit type casts for inline code since MSVC
3651 require them. Affected files lib/silcutil/silcbuffer.h,
3652 lib/trq/silcdlist.h and lib/trq/silclist.h.
3654 * Print warning in log files from now on if the packet
3655 decryption fails. Affected file silcd/server.c.
3657 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Changed the `say' client operation's interface to accept
3660 new `type' argument to indicate the type of the message sent
3661 by the library. The application may filter the library's
3662 messages according the type. The affected file is the
3663 lib/silcclient/silcapi.h.
3665 * Added two new functions to lib/silcclient/silcapi.h:
3666 silc_client_del_client and silc_client_del_client_by_id.
3667 Affected file lib/silcclient/idlist.c.
3669 * Moved the clientincludes.h from includes/ to silc/ and
3670 serverincludes.h from includes/ to silcd/.
3672 * The modes for the CMODE and CUMODE are now passed as
3673 uint32 for application with COMMAND_REPLY. The affected
3674 file is lib/silcclient/command_reply.c.
3676 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * /WHOIS without arguments shows client's own information.
3679 Affected file lib/silcclient/command.c.
3681 * Changed PING to not accept any arguments. The specs
3682 says that client can ping only the connected server so
3683 requiring an argument is not needed. Affected file is
3684 lib/silcclient/command.c.
3686 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Fixed a fatal bug in private message sending and reception
3689 encryption and decryption when using private message keys.
3690 The implementation was incorrect and did not follow the
3691 specification. It causd that some of the message were
3692 lost since it did not use the sending and receiving keys
3693 as the protocol suggests. This has been fixed and will cause
3694 incompatibilities with older clients when sending private
3695 message encrypted with private message keys. Affected files
3696 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3697 and various other in Irssi SILC Client.
3699 Added `responder' boolean argument to the functions
3700 silc_client_add_private_message_key[_ske] to indicate when
3701 the key is added as responder or initiator of the key
3704 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * Removed the silc_ske_check_version function and created
3707 a SilcSKECheckVersion callback. Added also a function
3708 silc_ske_set_callbacks that is now used to set all SKE
3709 callbacks. The callback functions are not given to
3710 the SKE functions anymore, but this function is used to
3713 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3715 * Added `silc_version' argument to the silc_client_alloc
3716 to define the version of the application for the library.
3717 The library will use the version string to compare it
3718 against the remote host's (usually a server) version
3719 string. Affected file lib/silcclient/silcapi.h
3721 * Added the KE protocol context to Key Agreement context
3722 in client library so that we can abort the SKE if it
3723 is in process when we get timeout. Affected file is
3724 lib/silcclient/client_keyagr.c.
3726 * Do not resolve the client ID forever if it returns in the
3727 first time that such client does not exist. This was done
3728 for example with private message. Affected file is
3729 lib/silcclient/client_prvmsg.c.
3731 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Do not add regex.h for WIN32. The affected file
3734 includes/silcincludes.h.
3736 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3737 not work yet 100%. It generates the DLL's automatically
3738 when compiling with --with-win32 under cygwin.
3740 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3742 * lib/contrib/regex.c is not compiled on WIN32.
3744 * Added silc_net_get_socket_opt function to the
3745 lib/silcutil/silcnet.h.
3747 * Added includes/silcwin32.h for WIN32 specific includes
3750 * Do not use ptime structure or any of the posix process
3751 functions on WIN32 in lib/silccrypt/silrng.c.
3753 * Added silc_gettimeofday to provide generic function
3754 for struct timeval on all platforms. Added the function
3755 to lib/silcutil/silcutil.h.
3757 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3760 library as they clearly belong there. As a plus side we
3761 can make the actual socket connection routines platform
3764 Added also new generic function silc_socket_read and
3765 silc_socket_write (that used to be silc_packet_[read/write].
3766 The implementation of these are platform specific.
3768 * Added WIN32 specific routines of silc_socket_[read/write]
3769 to lib/silcutil/win32/silcwin32sockconn.c.
3771 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3773 * Added preliminary support for native WIN32 compilation under
3774 cygwin (using the -mno-cygwin option for GCC) to the
3775 ./configure.in.pre. The --with-win32 now prepares the
3776 compilation for native WIN32.
3778 * Rewrote the SILC Scheduler interface in the file
3779 lib/silcutil/silcschedule.h. The scheduler is now context
3780 based and does not have anymore any global static scheduler.
3781 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3782 and created lib/silcutil/win32 directory for WIN32 based
3785 * Added Unix specific network routines to the
3786 lib/silcutil/unix/silcunixnet.c and the old
3787 lib/silcutil/silcnet.c includes now only generic routines.
3789 Added WIN32 specific network routines to the
3790 lib/silcutil/win32/silcwin32net.c.
3792 * Added Unix specific utility functions from the
3793 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3795 * Added WIN32 SILC Scheduler to the file
3796 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3799 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Do not handle JOIN notify in the server if the target client
3802 is not registered (idata->registered == FALSE). The affected
3803 file is silcd/packet_receive.c.
3805 * Update the nickrec->founder in event_cumode in the Irssi SILC
3806 client. Affected file irssi/src/silc/core/silc-channels.c.
3808 * Fixed the CUMODE_CHANGE notify handling in the server when
3809 server and router are announcing their clients on channels.
3810 Now the mode changes are saved and notified correctly. The
3811 affected file is /silcd/packet_receive.c.
3813 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3814 They really did not replace the cache entry in the ID Cache.
3815 Now they do that. Affected file silcd/idlist.c.
3817 * Fixed the KICK notify handling in the Irssi SILC client to
3818 update the channel records so that the kicked client does not
3819 appear to be on the channel. The affected file is
3820 irssi/src/silc/core/silc-channels.c.
3822 * Always update the conn->current_channel when executing command
3823 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3825 * Fixed the KILL notify handling in Irssi SILC client to remove
3826 the killed client on all channels.
3828 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Fixed the silc_parse_command_line to remove extra spaces
3831 from the start and end of the arguments. Affected file is
3832 lib/silcutil/silcutil.c.
3834 * Cancel and free any active protocol in the function
3835 silc_server_close_connection. Affected file silcd/server.c.
3837 * Cancel and free any active protocol in the function
3838 silc_client_close_connction. Affected file is
3839 lib/silcclient/client.c.
3841 * Do not execute the KILL command for clients that are in
3842 history (ie. they are not in the network). Affected file is
3845 * Fixed KILL notify handling, client does not crash anymore.
3846 Affected file irssi/src/silc/core/silc-channels.c.
3848 * Reduced the default packet buffer size from 2048 to 1024 in
3849 lib/silccore/silcpacket.c.
3851 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3852 counter to the SKE context that is incresed when the SKE library
3853 performs async operation outside the library. If the outside
3854 process frees the SKE context and FREED status will be set
3855 and the library will detect after the sync operation that the
3856 libary is freed. The affected files are
3857 lib/silcske/silcske[_status].[ch].
3859 * Resolve the client entry information in the function
3860 silc_client_channel_message to assure that NULL pointer is not
3861 passed as client entry to the application. */
3863 * Fixed the task timeout calculation to assure that there is
3864 never negative timeouts. The affected file is
3865 lib/silcutil/silcschedule.c.
3867 * Fixed the channel user mode notification sending in server.
3868 It was sent point-to-point to the router (or to server by router)
3869 but it needs to be destined to a channel. The routines now
3870 supports sending the channel user mode notifys to the channels
3871 when announcing clients and channels. Affected files are
3872 silcd/server.c and silcd/packet_receive.c.
3874 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3875 It did not actually replace the old channel entry in the cache.
3876 Affected file lib/silcclient/client_notify.c.
3878 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Fixed a possible crash in silc_packet_send_prepare. It now
3881 assures always that there is enough space in the buffer and
3882 at the tail area of the buffer (for MAC).
3884 Fixed the inbound buffer reallocation in silc_packet_read.
3885 It was old code and did not handle the reallocation correctly.
3888 The affected file is lib/silccore/silcpacket.c.
3890 * Fixed buffer overflow in silc_parse_nickname in the file
3891 lib/silcutil/silcutil.c.
3893 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * make install generates new server keys only if there is not
3898 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3901 Added check that if the NOREPLY is set then we will not send
3902 the away message. This avoids infinite loop of away messages
3903 if both clients are away. The affected file is
3904 lib/silcclient/client_prvmsg.c.
3906 * Fixed client crash if /NICK was given without arguments.
3907 Affected file lib/silcclient/command.c.
3909 * Server does not send the invite list in INVITE command back
3910 to the client if the list was not altered. Added this notion
3911 to the protocol spec as well. Affected file silcd/command.c.
3913 Fixed possible crash in INVITE command by checking the
3914 value of silc_server_get_client_route command.
3916 * Fixed the INVITE notify type handling. The arguments are now
3917 taken in correct order and client does not crash. The affected
3918 file is irssi/src/silc/core/silc-channels.c.
3920 Removed the "Inviting xxx to channel" message from the
3921 client library away and let the application handle it.
3922 Affected file lib/silcclient/command.c. Added that message
3923 to Irssi SILC client's message formats.
3925 * Fixed CMODE command crash in client. It now checks the
3926 amount of arguments correctly and does not crash. The affected
3927 file is lib/silcclient/command.c.
3929 * Do not create new channel automatically in silc_channels_join
3930 but check whether the channel by that name already exists.
3931 Affected file irssi/silc/core/silc-channels.c.
3933 * Do not send the SERVER_SIGNOFF to router if the disconnected
3934 entity was the router. Affected file silcd/server.c.
3936 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3937 SILC client as it was missing from there.
3939 Added the handling of the KICK notify to the Irssi SILC client
3940 as it was missing. Added "you have been kicked" message to
3941 Irssi SILC client's message modules formats.
3943 Added the handing of the KILL notify to the Irssi SILC client
3944 as it was missing. Added the kill message module formats
3947 The affected file is irssi/src/silc/core/silc-channels.c.
3949 * The router did not save the channel mode the server announced.
3950 Affected file silcd/packet_receive.c.
3952 * Fixed a possible crash in INFO command in server. If the
3953 server did not provide the server info it crashed. Affected
3954 file silcd/command.c.
3956 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Fixed the GETKEY command in the server to check also the
3959 global list. Otherwise the GETKEY would not work correctly
3960 in normal SILC server. Affected file silcd/command.c.
3962 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Fixed GETKEY crash, it crashed if the command did not succseed.
3966 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3969 is now real and not just an macro interface to GMP.
3971 Removed the entire GMP from the source tree and imported new
3972 NSS MPI library instead. Reason for removing GMP is that it is
3973 extremely large and compiles extremely slow. The NSS MPI
3974 is only a few files and compiles in less than 10 seconds.
3975 The speed is also about the same as GMP. The MPI is imported
3976 to lib/silcmath/mpi.
3978 If the system has GMP installed we will still use the GMP.
3979 If it is not then the NSS MPI will be compiled.
3981 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Merged a long nickname (127 characters long) crash bugfix from
3984 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3986 * Merged a freed memory reference bugfix from Irssi CVS tree.
3987 Affected file irssi/src/core/commands.c.
3989 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Added the server's public key sving and verification to the
3992 server when performing the SKE. This was missing and the
3993 remote server's (or router's) public key was accepted without
3994 checking whether we have it previously or trust it at all.
3995 Affected file silcd/protocol.c.
3997 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Check in the silc_server_timeout_remote if protocol is active
4000 and make sure that the protocol's final callback is called so
4001 that all memory if freed. Affected file silcd/server.c.
4003 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * silc_server_whois_send_reply crashed the server if the nickname
4006 was 127 characters long. Affected file silcd/command.c.
4008 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Added sanity check to the silc_server_new_client. If the hostname
4011 is provided inside username then check that the provided hostname
4012 really is the same as the resolved one. If the hostname was not
4013 resolved then check it from the public key. Affected file is
4014 silcd/packet_receive.c.
4016 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4017 if the server disconnected us and the connection is not valid
4018 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4020 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4021 the library to the lib/silcutil/silcutil.[ch].
4023 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Close log file after open. Affected file
4026 lib/silcutil/silclog.c.
4028 * Check whether sock == NULL in silc_client_send_packet and return
4029 if it is. Affected file lib/silcclient/silcclient.c.
4031 * Check rec->entry == NULL in the Irssi SILC Client before
4032 sending the channel message. Affecte file is
4033 irssi/src/silc/core/silc-servers.c.
4035 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Merged a splitted window bugfix from Irssi CVS tree. The
4038 affected file is irssi/src/fe-text/textbuffer-view.c.
4040 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4041 It did not print nickname.
4043 * Improved the distributions system a bit.
4045 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4048 irssi/src/fe-text/gui-window.c.
4050 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4051 to in-active server. The affected file is
4052 irssi/src/silc/core/client_ops.c.
4054 * Resolve the client in USERS command reply if the entry does
4055 not have username resolved. The affected file is
4056 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4057 command to WHOIS command to really resolve stuff. The USERS
4058 is not used any more in any critical section so WHOIS can
4059 be used even though it might be slower than IDENTIFY.
4061 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4064 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Changed the protocol API a bit more consistent in the
4067 lib/silccore/silcprotocol.[ch].
4069 * Changed the following headers to ROBODoc format:
4071 lib/silccore/silcpayload.h
4072 lib/silccore/silcprotocol.h
4073 lib/silccore/silcsockconn.h
4075 All core library headers are now formatted.
4077 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed a bug in Irssi SILC client; do not show that you are
4080 server/router operator if you really are not. Affected file is
4081 irssi/src/silc/core/client_ops.c.
4083 * Renamed silc_command_free_payload to silc_command_payload_free.
4084 Affected file lib/silccore/silccommand.h
4086 * Added silcmath.h to include the prototoypes of various routines
4087 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4090 * Changed the following headers to ROBODoc format:
4092 lib/silccore/silcchannel.h
4093 lib/silccore/silccommand.h
4094 lib/silccore/silcid.h
4095 lib/silccore/silcidcache.h
4096 lib/silccore/silcmode.h
4097 lib/silccore/silcnotify.h
4098 lib/silccore/silcpacket.h
4099 lib/silcmath/silcmath.h
4101 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Added checking to the server code not to start the server if
4104 ciphers and stuff are not configured properly. Affected files
4105 silcd/serverconfig.[h] and silcd/server.c.
4107 * Changed the layout of the header files of the public interfaces
4108 in the SILC libraries. The new layout supports ROBODoc
4109 documentation tool (and some others) so that it is easy to create
4110 a library reference manual. All the other headers and source
4111 code must still follow the CodingStyle document. Also source
4112 code must not include these ROBODoc stuffs, only the headers.
4113 Furthermore, all public interface headers must now be named
4114 by using `silc' prefix, example: silcapi.h, silccipher.h.
4115 Some files were renamed due to this. All the other headers
4116 must not be used as public interfaces. I will update the
4117 CodingStyle document later. Changed following headers, so far:
4119 lib/silcclient/silcapi.h
4120 lib/silccore/silcauth.h
4121 lib/silccore/silcprivate.h
4122 lib/silccrypt/silcdh.h
4124 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Removed silc_client_packet_send_flush from the client library
4129 as it is not needed. Affected file lib/silcclient/client.[ch].
4131 * Added printing of message of unresolved authentication method
4132 to the Irssi SILC client. Added it to the module formats.
4133 Removed the same message from the client library.
4135 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Added new distribution feature, DISTLABEL. Every distribution
4138 can define own preprocessor label that can be used in the
4139 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4140 file distributions, acconfig.h.pre and prepare.
4142 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Added Makefile.defines_int to include the actual definitions
4145 for Makefile.defines.in. Tested the new distribution system,
4146 created distributions and tested installation.
4148 * Added AWAY message printing to the Irssi SILC client. Added
4149 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4151 * Added SCONNECT command to call the SILC's CONNECT command.
4152 Cannot use CONNECT directly since Irssi uses that internally.
4153 Affected file irssi/src/silc/core/silc-servers.c.
4155 Added ACTION local command. It is same as ME command but takes
4156 the channel as mandatory argument.
4158 Rewrote some of the Irssi's help files to suite for SILC
4161 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Added Makefile.defines[.in] that should for now on be included
4164 in all Makefile.am file in the source tree. That file includes
4165 all common compilation definitions for SILC source tree.
4167 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Minor changes to the ./prepare script to change the package
4170 name according the distribution name to the configure.in.
4172 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Created new distribution system. Added file `distributions'
4175 that defines all the distributions that can be created out of
4176 the SILC source tree. The ./prepare script now reads that
4177 file to determine how to prepare the distributions. The
4178 first argument to the ./prepare is the name of the distribution
4179 and second is the version of the distribution. If given
4180 without arguments it creates the default (toolkit) distribution
4181 with the default version (defined in ./prepare).
4183 All Makefile.am files that are subject to the distributions
4184 are now named as Makefile.am.pre. These are ./Makefile.am
4185 and lib/Makefile.am. Others may be changed later.
4187 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Added invite list, ban list, some key management and connection
4190 error message printing to module formats in the Irssi SILC client.
4192 * Added new silc_client_set_away_message to set the away message
4193 that is back to the person who sent private message. The
4194 affected file lib/silcclient/silcapi.h and the
4195 lib/silcclient/client_prvmsg.c.
4197 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Fixed the private message sending in the Irssi SILC client,
4200 added local command KEY to the Irssi SILC client.
4202 Added key management and key agreement message formats to the
4203 irssi/src/fe-common/silc/module-formats.[ch].
4205 Added USERS (alias WHO) printing, server/router operator
4206 indication and LIST command printing to the module formats.
4208 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Fixed channel joining notify handling, cumode notify handling
4211 from Irssi SILC client.
4213 * Added SILC specific module-formats to the Irssi SILC client so
4214 that SILC specific message hilighting, colors etc is possible.
4215 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4217 Added channel mode, channel user mode, actions, notices,
4218 whois and whowas printing to the the module-formats.c.
4220 * Fixed a bug in channel deletion in the server. The channel
4221 is not left to the cache even if the channel founder auth mode
4222 is set when there are no users anymore on the channel. Affected
4223 file silcd/server.c.
4225 * The silc_net_localhost now resolves the entire hostname including
4226 the domain name. Affected file lib/silcutil/silcnet.c.
4228 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Changed the ask_passphrase client operation to be ascynchronous.
4231 It has now a completion callback and a context that the
4232 application must call after it has got the passphrase from
4233 the user. Affected files lib/silcclient/silcapi.h,
4234 lib/silcclient/protocol.c, lib/silcclient/command.c and
4237 Added SilcAskPassphrase callback that the application calls
4238 to deliver the passphrase to the library.
4240 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4241 The public key verification and especially a certificate
4242 verification is asynchronous procedure.
4244 Added new SILC_SKE_STATUS_PENDING status to indicate the
4245 request is pending and a callback will be called to finalize
4248 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4249 indicate that remote end did not send its public key (or
4250 certificate), even though we require it. Added check for this
4251 condition in the SKE. This was a security bug, now fixed.
4253 Defined new SilcSKEVerifyCbCompletion callback that is called
4254 when the verification process is completed.
4256 The affected files lib/silcske/silcske_status.h and
4257 lib/silcske/silcske.[ch].
4259 * Changed the verify_public_key client operation to be async
4260 as well. Defined SilcVerifyPublicKey callback that is used to
4261 indicate the success of the public key verification process.
4263 Changed the server and client to use the new async client
4266 * Changed the Irssi SILC client's internal scheduler to be called
4267 twice as many times as it used to be. As a result the client
4268 should be a bit faster now. Affected file is
4269 irssi/src/silc/core/silc-core.c.
4271 * Added support to Irssi SILC client of asynchronous public key
4272 verification and passphrase inquiry. Affected file is
4273 irssi/src/silc/core/silc-core.c.
4275 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Do not say "You have left channel %s" in client library.
4278 Moved it to the application. Affected files are
4279 lib/silcclient/command.c and silc/client_ops.c.
4281 * Fixed silc_client_get_clients. Command context was not
4282 duplicated and was freed memory in the callback. Affected
4283 file lib/silcclient/idlist.c.
4285 * Do not say "you are now talking..." on JOIN command in the
4286 client library. The appliation must handle it.
4288 * Do not say ".. changed topic to" in command reply in the
4289 client libary. The application must handle it.
4291 * Fixed TOPIC command sending in the client library.
4293 * Fixed a memory leak in silc_client_command_free in the file
4294 lib/silcclient/command.c.
4296 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Imported a modified version of Irssi client to the source tree.
4299 The Irssi will be used to create a new client called
4300 Irssi SILC. Imported to irssi/.
4302 Added silc_core_init_finish function to the Irssi. Affected
4303 file irssi/configure.in.
4305 A lot changes in the Makefile.ams around the irssi tree.
4307 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Do not rehash if the new size is same as the old size of the
4310 hash table, in the silc_hash_table_rehash*. The affected file
4311 lib/silcutil/silchashtable.c.
4313 * Replaced hash_table_del_by_context calls from the server
4314 (when channel->user_list and client->channels) to the
4315 hash_table_del as it is sufficient and faster.
4317 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Added silc_hash_table_list, silc_hash_table_get and the
4320 SilcHashTableList structure to provide an alternative way to
4321 traverse the hash table. The affected files are
4322 lib/silcutil/silchashtable.[ch].
4324 * Changed the server's idlist routines to use the hash table
4325 routines to optimize the code.
4327 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Replaced the client entry's `channel' list and channel entry's
4330 `user_list' list to hash tables for optimized lookup. Changed
4331 the code to use the hash table interface around the code.
4332 Affected file lib/silcd/idlist.[ch].
4334 * Added `auto_rehash' boolean argument to the function
4335 silc_hash_table_alloc to indicate whether the hash table should
4336 auto-rehash when it thinks is appropriate time. It will
4337 increase the hash table size if the there is twice as much
4338 entries in the table than the size of the table, and will
4339 decrease the size if there are twice as less entries than
4340 the size of the table.
4342 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4346 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * silc_idcache_purge_by_context deletes the entry now by context
4349 as it is supposed to do. Affected file lib/silccore/idcache.c.
4351 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4352 client is not anymore valid (WHOWAS givens the info) and not
4353 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4355 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Removed the `data' and `data_len' arguments from the ID Cache
4358 interfaces and added `name' argument. ID Cache does not handle
4359 anymore the binary data only a names associated with given ID.
4361 * When hashing a Client ID with silc_hash_id the entire ID is
4362 not hashed anymore, instead only the hash of the Client ID is
4363 hashed. This way we can access the Client ID from the cache
4364 with Client ID but with the hash of the ID (which is a hash of
4365 the nickname) as well without any difference in performance.
4367 Added also silc_idcache_find_by_id_one_ext to do one on one
4368 searching when we have the actual ID. Added also function
4369 silc_hash_client_id_compare. The affected files are
4370 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4372 * When hashing the name associated with a ID it is always done
4373 in lowercase. This way we can access the cache without worrying
4374 about case-sensitivity, even though, for example nicknames are
4377 * Fixed a bug in server with channel message sending. It put
4378 wrong ID type as destination ID. The affected file
4379 silcd/packet_send.c.
4381 * silc_idcache_del_by_context now deletes from all hash tables
4382 by context. Affected file lib/silccore/idcache.c.
4384 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Changed the client library to use the new ID Cache interface.
4387 Changes around the source tree.
4389 * Added silc_hash_table_rehash_ext to rehash with specific
4390 hash function. Affected file lib/silcutil/silchashtable.[ch].
4392 * Added silc_hash_string_compare to compare two strings in the
4393 hash table. Affected file lib/silcutil/silcutil.[ch].
4395 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added new function silc_idcache_del_by_context into the
4398 lib/silccore/idcache.[ch].
4400 * Changed the server's ID list routines to use the new ID Cache
4401 interface. Changes around the source tree.
4403 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Added silc_hash_table_del[_by_context]_ext functions in to the
4406 lib/silcutil/silchashtable.[ch].
4408 Removed silc_hash_table_find_all* routines and added new
4409 silc_hash_table_find_foreach to replace them.
4411 Added silc_hash_table_replace_ext function as extended
4412 replacing function. Separated the simple hash table interface
4413 from the extended hash table interface in the file
4414 lib/silcutil/silchashtable.h.
4416 * Fixed minor bugs and changed it to use some of the new
4417 hash table functions in lib/silccore/idcache.c
4419 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Added new function silc_hash_table_find_all to return all keys
4422 in the hash table by the specified key. As the hash table is
4423 collision resistant it also makes it possible to have several
4424 duplicate keys in the hash table. This function may be used to
4425 find all of the keys from the hash.
4427 Added user_context arguments to the SilcHashFunction,
4428 SilcHashCompare and SilcHashDestructor to deliver user specified
4431 Added new fuctions silc_hash_table_find[_all]_ext to do
4432 extended lookup with specified hash and compare functions and
4433 specified user contexts.
4435 Added new function silc_hash_table_add_ext to add the key
4436 with specified hash function and user context.
4438 Added new function silc_hash_table_foreach to traverse all
4439 entrys in the hash table. Added SilcHashForeach callback
4442 Added new function silc_hash_table_del_by_context to delete
4443 the entry only if the context associated with the key matches.
4445 Affected files are lib/silcutil/silchashtable.[ch].
4447 * Removed silc_hash_[server/client/channel]_id and added just
4448 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4449 silc_hash_id_compare to compare two ID's using as the hash table
4450 comparison function. Added also silc_hash_data to hash
4451 binary data and silc_hash_data_compare to compare it.
4453 * Removed silc_idlist_find_client_by_hash as it is not needed
4454 anymore. Affected file silcd/idlist.[ch].
4456 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4457 to use internally the SilcHashTable. The new ID Cache is a lot
4458 faster than the old one. Some of the ID Cache interface was also
4459 rewritten and obsolete and stupid functions were removed.
4461 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added entry_count field to the SilcHashTable to keep the number
4464 of the entries in the table. Implemented the function
4465 silc_hash_table_rehash. Added new function
4466 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4468 Fixed a minor bug in silc_hash_table_free.
4470 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4471 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4472 into the lib/silcutil/silcutil.[ch].
4474 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Implemented a collision resistant hash table into the
4477 lib/silcutil/silchashtable[ch]. See the header and the source
4478 for the SilcHashTable API.
4480 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Merged dotconf version 1.0.2 into lib/dotconf.
4484 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Do not compile anything in lib/silcsim/* if the SIM support
4487 is not enabled. The tree should now compile without problems
4490 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Compiled the SILC under cygwin. Compiled and tested briefly
4493 without problems. More tests needed. The SIMs didn't compile
4496 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4498 * Fixed possible crash in silc_get_username in the
4499 lib/silcutil/silcutil.c.
4501 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Fixed a va_arg in silc/client_ops.c.
4505 * Oops, RC5 routines were named AES and caused some problems
4506 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4508 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Added new SilcIDIP structure into the lib/silccore/id.h and
4511 replaced the old `ip' fields from all SILC ID's to that type.
4512 This is a step towards IPv6 support.
4514 The silc_id_get_len takes now the ID as an extra argument.
4515 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4516 both IPv4 and IPv6 based ID's.
4518 The affected files are lib/silccore/id.[ch] and other files
4519 around the tree using these routines.
4521 * Removed the ID length arguments in server from various
4522 silc_server_send_notify_* routines -> they are not needed
4525 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Fixed memory leak in silc_encode_pem_file in the file
4528 lib/silcutil/silcutil.c.
4530 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Check minor version as well in the SKE. Affected files are
4533 silcd/protocol.c and lib/silcclient/protocol.c.
4535 * Added --identifier option to the server so that an identifier
4536 can be when creating the public key for the server. Affected
4537 file is silcd/silcd.c.
4539 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4540 lib/silccrypt/silcpkcs.c.
4542 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Register default ciphers and stuff when using -C option with
4545 the server. Affected file sildc/silcd.c.
4547 * Put back the servers public key filename format, it is better
4548 than the new one. For now, the client keys are saved with the
4549 new filename format. The affected file silc/client_ops.c.
4551 * Implemented the Cipher API for the rest of the ciphers that
4552 did not implement it or implemented it the wrong way.
4554 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * Register default ciphers and stuff when using the -S option
4557 in the client. Affected file silc/silc.c. Same also when
4558 creating new key pair with -C option.
4560 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Fixed the silc_verify_public_key client operation function to
4563 save the public keys differently. The fingerprint is now
4564 used as filename and not the hostname. This way also the
4565 client keys are saved uniquely and not with hostnames. The
4566 affected file is silc/client_ops.c.
4568 * Trimmed the silc_hash_fingerprint function to remove extra
4569 whitespaces from the end of the fingerprint. The affected
4570 file is lib/silccrypt/silchash.c.
4574 * Added silc_cipher_register_default function to register all
4575 default ciphers. It can be used when configuration files
4576 does not exist and the application does not want any specific
4577 ciphers in any specific order.
4579 The SilcDList is now used as silc_cipher_list dynamically
4580 allocated cipher list. Removed the static list all together
4581 and now all ciphers must be allocated to the dynamic list.
4582 The silc_cipher_alloc routine was changed to check only the
4585 All silc_cipher_* routines that used to return int returns
4588 The affected files lib/silccrypt/silccrypt.[ch].
4590 * The same thing was done to silc_hash_* as for silc_cipher_*
4591 routines. Affected files lib/silccrypt/silchash.[ch].
4593 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4594 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4595 Added also silc_pkcs_[un]register[_default] functions.
4596 Removed the data_context from the PKCS API.
4598 * Added silc_hmac_register_default function to register default
4599 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4600 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4601 to unregister all hmacs at once.
4603 * Register the default ciphers, hash functions, PKCSs and HMACs
4604 if client's configuration file does not exist. The affected
4607 * The client did not load the hash functions from the SIM
4608 modules at all. Added support for this. Affected file is
4609 silc/clientconfig.c.
4611 * When decoding public key with silc_pkcs_public_key_decode, check
4612 the supported algorithm only if PKCS are registered. Affected
4613 file lib/silccrypt/silcpkcs.c. The same was done with the
4614 silc_pkcs_private_key_decode.
4616 * Fixed the SILC List routines to keep the list always in order.
4617 It used to change the list's order when traversing the list but
4618 not it preserves the order. Affected file lib/trq/silclist.h.
4620 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added the client library to use the SilcSocketConnection's
4623 reference counter (by silc_socket_dup) to prevent the bug that
4624 the socket object may be freed underneath async operation.
4626 * The name resolv library checking fixes in the configure.in.pre.
4629 * Created new version of the protocol drafts for future
4630 development. The -03 drafts are the ones that will be changed
4631 in the trunk now and the -02 will remain as they are.
4633 * Send list of CUMODE notifys to the router when announcing
4634 the channel users to the router. Affected file silcd/server.c.
4635 If the router receiving channel founder CUMODE for a channel
4636 that already has channel founder it will send CUMODE notify
4637 to the sender to remove the channel founder rights from the
4638 announced client. Affected file silcd/packet_receive.c.
4640 * The CUMODE notify may now use Server ID as well as the entity
4641 who changes the mode. Updated protocool specs.
4643 * Updated INSTALL and README files.
4645 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * New web pages in the http://silc.pspt.fi. The pages was
4652 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Implemented the [DenyConnectin] config section in the server.
4655 Added silc_server_config_denied_conn to check whether incoming
4656 connection is denied. Affected file silcd/serverconfig.[ch].
4658 * Do not check the ports when checking the incoming configuration
4659 data if the port is 0, meaning any. Affected file is
4660 silcd/serverconfig.c.
4662 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Fixed buffer overflow in silc_string_compare in the file
4665 lib/silcutil/silcutil.c.
4667 * Fixed double free in silc_server_command_leave in the file
4670 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Fixed the version checking in the server. Affected file is
4675 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Fixed the configuration data fetching when accepting new
4678 connections in the server. Affected file silcd/server.c.
4680 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Added `sender_entry' argument to the function
4683 silc_server_packet_relay_to_channel so that we can check
4684 whether some destination actually belongs to the same route
4685 the sender belongs (ie, we must not resend the packet to the
4686 sender). Affected file silcd/packet_send.[ch].
4688 * Added `servername' field to the SilcClientEntry in the server
4689 to hold the name of the server where client is from. Affected
4690 file is silcd/idlist.h.
4692 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Moved the channel message encrypting in the router betwen
4695 router connections from silc_server_channel_message to the
4696 silc_server_packet_relay_to_channel since we want to check
4697 whether we have anybody channel before encrypting anything.
4698 Affected files silcd/packet_[receive/send].c.
4700 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed the [AdminConnection] server config section to support
4703 multiple entries. Affected file silcd/serverconfig.c.
4705 * Added support into the server to check the validity of the
4706 incoming connection before executing any KE or authentication
4709 * The connection configuration is now saved to the KE and
4710 connection auth protocol contexts and not fetched anymore in
4711 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4713 * The local hosts listenning address and port is also resolved
4714 now when starting the server. We want to have the socket object
4715 to include the real address and port for the listener. Added
4716 new function silc_net_check_local_by_sock into the files
4717 lib/silcutil/silcnet.[ch].
4719 * Fixed a broadcast bug in server -> do not broadcast if we
4722 * Fixed a routing bug. Do not route broadcast packets ever.
4723 Broadcast packets must be processed always and not routed since
4724 they may be destined to some other host than yourself and thus
4725 would get routed without no good reason. Affected file is
4728 * Added function silc_server_config_is_primary_route to check
4729 whether primary router connection has been configured (a router
4730 configuration that we are initiating). If there is not, we
4731 will assume that there is only two routers in the SILC network
4732 and we will use the incoming router connection as our primary
4733 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4735 * Changed the order of the broadcasting. Broadcast _after_ the
4736 packet has been processed not before. Affected file is
4739 * Fixed a [ClientConnection] parsing bug. The port was never
4740 parsed correctly thus resulting to port 0. Affected file
4741 silcd/serverconfig.c.
4743 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4744 argument and did not set the broadcast packet flag. Affected
4745 file silcd/packet_send.c. Fixed same bug in the function
4746 silc_server_send_notify as well.
4748 * If we receive NEW_ID packet for our own ID in the server, ignore
4751 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Removed the nickname from the Private Message Payload.
4756 Updated the code and the protocol specs.
4758 * Updated protocol specs for submitting to the IETF.
4760 * Tweaked the Random Number Generator a bit. Affected file
4761 lib/silccrypt/silcrng.c. Exported a new function
4762 silc_rng_[global]_add_noise which can be used to add more
4765 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Do not parse packets with different timeout when protocol
4768 is active -> may cause problem with rekey. Affected file
4771 * When server receives signoff notify it must not create
4772 new channel key if the client is on any channels since the
4773 sender of the signoff notify will create it.
4775 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Added printing of error messages during SKE protocol from the
4778 failure packet sent by server during SKE. Affected file
4781 * Removed the client's failure_callback handling with timeout
4782 and handle it immediately when received.
4784 * The SKE library returned wrong type in SUCCESS and FAILURE
4785 packets. They must be 32 bit MSB not 16 bit MSB.
4787 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Ok, rewrote the logic of the re-key and now it seems to work.
4790 I tested it on high traffic with frequent re-keys without
4791 problems. Added hmac_receive (and renamed hmac to hmac_send)
4792 in SilcClientConnection in lib/silcclient/client.h and
4793 in SilcIDListData in silcd/idlist.h. Also, removed the
4794 SilcPacketParserContext's cipher and hmac fields as they are
4795 not needed anymore and actually caused some problems when
4796 the ciphers and hmac's changed underneath the packet parser.
4798 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * If re-key protocol is active then process the incoming packets
4801 synchronously since we must assure that icoming packets encrypted
4802 with the old key is processed before the new keys is set to
4803 use. This is true other packets than for REKEY packets.
4804 Affected file silcd/server.c. The same was done to client library
4805 as well, affected file lib/silcclient/client.c.
4807 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Fixed bug in client and server to accept the force send if
4810 the packet is send from silc_[server/client]_packet_process
4811 function. Otherwise the packets are never delivered, oops.
4813 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Disable force sending of packets when REKEY protocol is active.
4816 We must assure that no packet is sent directly when rekey is
4817 performed. All packets must be sent through packet queue.
4818 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4819 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4820 function is silc_[server/client]_packet_send_real to check
4823 * Replaced the SIM paths from example config files to
4824 /usr/local/modules. Also, make install creates now
4825 /usr/local/silc/logs directory to hold all the SILC server
4828 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Made the configure.in.pre work on Solaris. Patch by salo.
4832 * Made all ciphers compatible with non-x86 machines. Defined
4833 CBC mode macros into lib/silccrypt/ciphers_def.h.
4835 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Fixed the make install.
4839 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * When MAC computation fails the silc_packet_decrypt returned 0
4842 even though it was supposed to return -1. Fixed this. The
4843 affected file is lib/silccore/silcpacket.c.
4845 * Do not replace the config files in /etc/silc (in make install)
4846 if they already exist. Affected file ./Makefile.am.
4848 * Do not send re-key packets immediately but through packet queue.
4849 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4851 * Changed silc_net_check_host_by_sock to return FALSE if the
4852 IP/DNS could not be resolved. Though, it returns the IP address
4853 now even if it could not resolve it (but returns also FALSE).
4854 Affected file lib/silcutil/silcnet.[ch].
4856 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Added silc_pkcs_decode_identifier to decode the public key's
4859 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4860 Added also silc_pkcs_free_identifier. Added also new context
4861 SilcPublicKeyIdentifier.
4863 * Added -S option to the silc client. It is used to dump the
4864 contents of the specified public key file.
4866 * Changed the PKCS api to return the public key length when
4867 setting the public key.
4869 * Fixed a fatal bug in the public and private key file loading.
4870 Affected file lib/silccrypt/silcpkcs.c.
4872 * Execute the packet parsing for client with zero (0) timeout
4873 if the protocol is active. Affected file silcd/server.c.
4875 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Made the key generation options to the silcd program. Added
4878 -C option, equivalent to client's option.
4880 * Added new [ServerKeys] config section to the server. It
4881 configures the server's public and private key.
4883 * Defined generic Public Key Payload into the protocol
4884 specification to send specific type of public keys and
4887 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4888 public key or certificate.
4890 * Implemented the GETKEY command to the server and to the
4891 client library and on user interface.
4893 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Made preliminary `make install' work.
4897 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added SilcServerRekey context into silcd/idlist.h.
4901 * Added the PFS support as defined in the specification to the
4902 SKE protocol. Affected files lib/silcske/*.c.
4904 * Added `ske_group' field to the SilcServerRekey context to hold
4905 the number of the SKE group that is used with PFS in re-key.
4906 Affected file silcd/idlist.h.
4908 * Added PFS re-key support to the server. Affected file is
4911 * Added silc_protocol_cancel to cancel execution of the next
4912 state of the protocol. Affected file is
4913 lib/silccore/silcprotocol.[ch].
4915 * Added the re-key support with and without PFS to the client
4916 library. Re-key is performed once in an hour, by default.
4918 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4919 Added silc_client_rekey_callback and silc_client_rekey_final.
4920 Affected files are lib/silcclient/protocol.[ch] and
4921 lib/silcclient/client.[ch].
4923 * Removed the `hmac_key' and `hmac_key_len' fields from the
4924 SilcClientConnection structure; not needed. Affected file is
4925 lib/silcclient/client.h.
4929 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Do not ask whether user wants to use the negotiated private key
4932 for private messages, just use it. Affected file is
4933 silc/local_command.c.
4935 * Added `send_enc_key' and `enc_key_len' fields to the
4936 SilcIDListData structure since they are needed in the re-key
4937 phase. Affected file is silcd/idlist.[ch].
4939 * Implemented the simple re-key protocol into the server.
4940 Affected files silcd/server.c and silcd/protocol.[ch]. The
4941 re-key will be performed once in an hour, by default.
4943 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4944 Added silc_server_rekey, silc_server_rekey_callback and
4945 silc_server_rekey_final.
4947 * Removed Tunneled flag from the protocol. Updated the code
4948 and the specifications.
4950 * Adde `pfs' field to the SilcIDListData to indicate whether
4951 the PFS is to be performed in the re-key. Affected file is
4954 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4957 int64 of at least the xintXX size. If void * is less that 4
4958 bytes uint32 * will be used. Defined bool as boolean.
4960 * Changed _ALL_ unsigned long and unsigned int to uint32,
4961 unsgined short to uint16 in the source tree.
4963 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4964 not handle clients that has entry->data.registered == FALSE.
4965 They are not in the network anymore. Affected file is
4968 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Implemented the sending of the SERVER_SIGNOFF notify in the
4971 server. Affected file is silcd/server.c.
4973 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4974 Added also silc_notify_payload_encode_args into the
4975 lib/silccore/silcnotify.[ch].
4977 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4978 Affected file silcd/packet_receive.c.
4980 * Implemented the SERVER_SIGNOFF notify handling in the client
4981 library. Affected file lib/silcclient/client_notify.c. Also,
4982 implemnted the printing of the SERVER_SIGNOFF info to the
4983 application. Affected file silc/client_ops.c.
4985 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4986 if the deleting was successful. Affected file silcd/idlist.[ch].
4988 * Added support for public key authentication in the connection
4989 authentication protocol in the client library. Affected file
4990 lib/silcclient/protocol.c.
4992 * Changed the server's silc_idlist_get_clients_by_* interface
4993 to support already allocated array so that new entries may be
4994 added to pre-allocated array. Affected file silcd/idlist.[ch].
4995 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4996 and command replies.
4998 * All command reply functions in the server now calls the
4999 pending command callback even if error occured. This way the
5000 error will be delivered to the client as well. Affected files
5001 silcd/command.c and silcd/command_reply.c.
5003 * Fixed INFO command to return local server's info if no server
5004 was provided. Affected file lib/silcclient/command.c.
5006 * Removed RESTART command for good. Updated the code and the
5009 * Rewrote parts of the task system. It is a bit simpler now.
5010 Removed unsued task priorities. The affected files are
5011 lib/silcutil/silctask.[ch].
5013 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Moved the USERS printing from the library to the application.
5016 Affected files lib/silcclient/command.c and silc/client_ops.c.
5018 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Added channel key re-key support. The re-key is perfomed
5023 only by the router and is done once in an hour. Added `rekey'
5024 field to the SilcChannelEntry in the server. Affected files
5025 silcd/server.c and silcd/idlist.h.
5027 * Added silc_task_unregister_by_context into the file
5028 lib/silcutil/silctask.[ch].
5030 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Added SILC_UMODE_GONE mode to indicate when the client is not
5033 present in the SILC network. Added also support to the local
5034 command AWAY that will set this mode. Added support of showing
5035 "xxx is gone" in WHOIS command. The USERS command shows the
5036 gone status as well.
5038 * Fixed setting server and router operator privileges in the
5039 server's UMODE command. Affected file silcd/command.c.
5041 * Merged the SKE KE1 and KE2 payloads into one payload. The
5042 new KE payload is equivalent to the old KE2 payload.
5044 Cleaned up the SKE Start Payload parsing. It now uses the
5045 simple buffer unformatting to do the parsing. A lot faster
5048 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5049 to the SKE that is used to indicate whether both of the SKE
5050 parties should perform authentication. By default only the
5051 responder performs authentication. By setting this flag also
5052 the initiator must do authentication. By default it is unset
5053 since in normal SKE case, client to server connection, only
5054 the responder should do authentication. When doing SKE between
5055 two clients both should perform authentication. Updated the
5056 code and the protocol specs.
5058 * A little fix to IDENTIFY command in the server. Search the
5059 client first by hash not nickname. Affected file is
5062 * Fixed the silc_client_close_connection to support closing
5063 the client to client connections wihtout deleting too much
5064 data. Affected file lib/silcclient/client.c.
5066 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5067 are received if protocol used to be active but is not anymore
5068 the application would crash due to NULL pointer dereference.
5069 Affected files silcd/server.c and lib/silcclient/client.c.
5071 * Added `hash' field to the SilcClientConnection to include
5072 the hash function negotiated in the SKE protocol.
5074 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5075 to set the channel founder authentication data. A client can
5076 claim the founder rights later by providing the authentication
5077 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5078 This way the channel founder can regain the channel founder
5079 privileges even it is left the channel. This works only on
5080 local server and the client must be connected to the same
5081 server to be able to regain the founder rights. Updated the
5082 protocol specs accordingly.
5084 Added support to the CMODE command in the client to set the
5085 founder auth data. Read the README to see how to set it.
5087 Added support to the CUMODE command to claim the founder
5088 rights. Read the README to see how to do it.
5090 Added support for the founder authentication to the Channel
5091 Entry in the server. Affected file silcd/idlist.h.
5093 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5094 server's CMODE command. Affected file silcd/command.c.
5096 * Added the following new functions into lib/silccore/silcauth.[ch]:
5097 silc_auth_get_method and silc_auth_get_data.
5099 * The server now saves the remote hosts public key to the
5100 SilcIDListData pointer. Affected file silcd/protocol.c.
5102 * The normal server now does not remove the channel entry from
5103 the cache if the founder authentication data is set. It used
5104 to remove it if the founder was the last one on the channel on
5105 the server and left the channel. The auth data is saved and
5106 if the channel is re-joined later the old entry is used with
5107 the old auth data. Affected files silcd/command_reply.c and
5110 * Removed the `pkcs' field from the SilcIDListData structure
5111 in the server; it is not used. Affected file silcd/idlist.h.
5113 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Fixed packet processing on slow links. Partial packets were
5116 never re-processed because the incoming data buffer was cleared
5117 by the application. Application must not directly clear the
5118 sock->inbuf, the packet processing routines handle it. Fixed
5119 this in client library and in server.
5121 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5123 * Fixed the WHOIS and IDENTIFY send reply function to really
5124 check whether to send list or just one entry. Affected file
5127 * Cleaned up the LEAVE command's channel key distribution. The
5128 affected file silcd/command.c.
5130 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5131 can enforce the channel mode as well. In that case the ID
5132 includes the ID of the server. The code now enforces the
5133 mode change if the router have different mode than the server.
5135 * The notify client operation with CMODE_CHANGE notify can now
5136 return NULL client_entry pointer if the CMODE was not changed
5137 by client. Application must check for this.
5139 * Added <Server ID> argument to INFO command to support server
5140 info fetching by Server ID.
5142 * Added silc_server_announce_get_channel_users to get assembled
5143 packets of channel users of the specified channel. Affected
5144 file silcd/server.[ch].
5146 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5147 was freed underneath the ID Cache.
5149 * Re-announce clients when the server received CHANNEL_CHANGE
5150 notify from the router. Affected file silcd/packet_send.c.
5152 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5155 crashed since it did not handle the fact that there is no cipher
5156 called "3" and didn't check the error condition. Now fixed.
5158 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5159 flag. It can be used to send message requests.
5161 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Implemented the RESTART command in the client.
5165 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5166 notice type messages. Added notice printing to the user
5169 * The channel keys are not re-generated if the channel's mode
5170 is PRIVKEY, ie private key on the channel exists. Affected
5171 files silcd/server.c and silcd/command.c.
5173 * Fixed a little bug in channel message delivery when channel
5174 private keys are set in the server. Affected file is
5175 silcd/packet_send.c.
5177 * Changed the setting on channel->on_channel = TRUE from the
5178 silc_client_save_channel_key to the JOIN command reply. The
5179 key payload is not received if the private channel key is set.
5180 Affected file lib/silcclient/command_reply.c and the
5181 lib/silcclient/client_channel.c.
5183 * When the CMODE_CHANGE notify is sent and the channel private
5184 key mode is removed the channel key must be re-generated in
5185 other cells as well. Added this support for the router in the
5186 silcd/packet_receive.c.
5188 * Added new local command NOTICE to send notice message on
5189 channel. Affected file silc/local_command.[ch].
5191 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Added new local command ME to the client. It is used to send
5194 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5195 some action. Affected file silc/local_command.[ch].
5197 * Changed channel_message and private_message client operations
5198 to deliver the message flags to the application. Added also
5199 the `flags' arguments to the silc_client_send_channel_message
5200 and silc_client_send_private_message functions. Affected file
5203 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Redefined the Private Message Payload to support private message
5206 keys and to support the new private message flags. Updated
5207 the protocol specs. Flags makes it possible to have for example
5208 CTCP style messages.
5210 * Added new type SilcPrivateMessagePayload and defined an API
5211 for it in the lib/silcclient/silcprivate.[ch].
5213 * Tested private message private keys successfully. Tested the
5214 private message key set, unset and list commands with the new
5217 * Redefined the Channel Message Payload to include the channel
5218 message flags (equal with private message flags) to support
5219 for example CTCP style messages.
5221 * Defined some of the message (for channel and private message)
5222 flags. Updated the protocol specs and added the flags to the
5223 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5225 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Added SilcKeyAgreementStatus type to the key agreement routines
5228 to indicate the current status and error if one occured.
5229 The status types are defined in the lib/silcclient/silcapi.h.
5231 * Added new local command KEY that is used to set and unset private
5232 keys for channels, set and unset private keys for private messages
5233 with remote clients and to send key agreement requests and
5234 negotiate the key agreement protocol with remote client. The
5235 key agreement is supported only to negotiate private message keys,
5236 it currently cannot be used to negotiate private keys for channels,
5237 as it is not convenient for that purpose.
5239 * Fixed a minor pending callback setting bug in the function
5240 silc_client_get_client_by_id_resolve, now the function works.
5241 Affected file lib/silcclient/idlist.c.
5243 * Added function silc_net_get_local_port to get local bound
5244 port by socket. Added to lib/silcutil/silcnet.[ch].
5246 * Added `sockets' and `sockets_count' fields to the SilcClient
5247 object. They hold the sockets of the listenning sockets in
5248 the client. Listenning sockets may be for example the key
5249 agreement server. Affected file lib/silcclient/client.[ch].
5250 Added functions the silc_client_add_socket and the
5251 silc_client_del_socket. They are exported to the application
5254 * Added ~./silc/clientkeys to support other client's public keys.
5256 * Renamed verify_server_key client operation to verify_public_key
5257 and added one argument to indicate the type of the connection
5258 (server, client etc.).
5260 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Added silc_server_connection_auth_request to handle the
5263 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5264 silcd/packet_receive.[ch].
5266 * Added silc_server_send_connection_auth_request into the
5267 silcd/packet_send.c to send the connection auth request packet.
5269 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5272 * Fixed the public key authentication in responder side in the
5273 server. The `auth_data' pointer includes the SilcPublicKey
5274 not the path to the public key. Affected file silcd/protocol.c.
5276 * Implemented the public key authentication in the initiator side
5277 in the server. Affected file silcd/protocol.c.
5279 * Removed the [RedirectClient] config section from the server
5280 configuration. Is not needed and I don't want to implement it.
5282 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Cleaned up the CMODE command in the server. It now works
5285 correctly and supports all the modes defined in the protocol.
5286 Affected file is silcd/command.c.
5288 * Added `hmac_name' field to the SilcChannelEntry in the server
5289 to hold the default HMAC of the channel. It can be set when
5290 creating the channel (with JOIN command). Affected files
5293 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5294 type to indicate the change of the current cipher and hmac
5295 on the channel. Client can safely ignore the <cipher> argument
5296 (if it chooses to do so) since the CHANNEL_KEY packet will
5297 force the channel key change anyway. The <hmac> argument is
5298 important since the client is responsible of setting the new
5299 HMAC and the hmac key into use.
5301 * Fixed the CMODE command in the client library as well.
5303 * Tested CMODE command in router environment successfully.
5305 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Show the version of the remote client (or server) when connecting
5308 to the server. It is logged to the log file. Affected file
5309 is silcd/protocol.c.
5311 * Fixed the KILLED notify handling in the client library. The
5312 client must be removed from all channels when receiving the
5315 Also, do not remove the client entry when giving the KILL
5316 command but when the KILLED notify is received.
5318 * Removed silc_idlist_find_client_by_nickname from the server.
5319 Not needed anymore. Affected files silcd/idlist.[ch].
5321 * Implemented the CHANNEL_CHANGE notify type handling to the
5322 server. Affected file silcd/server.c.
5326 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Added silc_server_send_notify_invite to send the INVITE
5329 notify between routers.
5331 * Implemented the INVITE command correctly to the server.
5333 * Implemented the INVITE notify type handling in the server.
5335 * Implemented the INVITE command to the client library and on the
5338 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Added function silc_server_get_client_resolve to find the
5341 client entry by ID from all ID lists and then resolve it
5342 (using WHOIS) if it cannot be found. Affected file is
5345 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * Implemented the BAN command to the client library.
5349 * The JOIN command in the server now checks the invite list
5352 * Changed the silc_command_reply_payload_encode_va and the
5353 silc_command_payload_encode_va to support that if argument is
5354 NULL it ignores and checks the next argument. Affected file
5355 lib/silccore/silccommand.c.
5357 * Added silc_server_send_notify_ban to send the BAN notify
5358 type between routers.
5360 * Chaned the silc_notify_payload_encode to support that if
5361 argument is NULL it ignores and checks the next argument.
5362 Affected file lib/silccore/silcnotify.c.
5364 * Tested ban lists in router environment successfully.
5366 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Implemented BAN command to the server, in silcd/command.[ch].
5370 * Removed the BAN and INVITE_LIST modes from the CMODE command
5373 * Added function silc_string_match to regex match two strings.
5374 Affected files lib/silcutil/silcutil.[ch].
5376 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Redefined parts of the SilcChannelEntry in the server to support
5379 the new ban and invite lists.
5381 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Redefined the INVITE command. The same command can be used to
5384 invite individuals to the channel but also to manage the invite
5385 list of the channel (to add to and remove from the invite list).
5386 Updated the protocol specs.
5388 * Added new command SILC_COMMAND_BAN that can be used to manage
5389 the ban list of the channel. Updated the protocol specs.
5391 * Removed the channel modes: the SILC_CMODE_BAN and the
5392 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5393 in the CMODE command. The equivalent features are now available
5394 using INVITE and BAN commands. Updated the protocol specs.
5396 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5397 in the network about change in the current ban list. The notify
5398 type is not used by the client.
5400 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5401 support the invite lists.
5403 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Added new function silc_string_regexify that converts string
5406 including wildcard characters into regex string that can
5407 be used by the GNU regex library. Added into the file
5408 lib/silcutil/silcutil.[ch].
5410 Added silc_string_regex_combine to combine to regex strings
5411 into one so that they can be used as one regex string by
5412 the GNU regex library. Added into the file
5413 lib/silcutil/silcutil.[ch].
5415 Added silc_string_regex_match to match two strings. It returns
5416 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5418 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Imported GNU regex to the soruce tree into lib/contrib.
5421 Fixed some compiler warning from the regex.c.
5423 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Fixed MOTD command in the server to work in router environment.
5427 * Fixed the MOTD command in the client library to support
5428 the server argument in the command.
5430 * Added `nickname_len' argument to the silc_idlist_add_client
5431 in the server, as the `nickname' argument may be binary data
5434 * Added silc_idlist_get_channels to return all channels from
5437 * Implemented LIST command to the server. Affected file is
5440 * Implemented the LIST command to the client library and on the
5443 * Added [<user count>] argument to the LIST command reply.
5444 With private channels the user count is not shown.
5446 * Updated TODO and README.
5448 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * The client entry's data.registered must be TRUE even with
5451 global client entry on global client list. The data.registered
5452 is used to check whether the client is anymore in the network,
5453 for example with WHOWAS command so it must be valid.
5455 * Fixed the WHOWAS command in the server. It now actually works
5456 in router environment. Added function into silcd/command_reply.c
5457 silc_server_command_reply_whowas_save.
5459 * Added silc_idlist_purge function to the silcd/idlist.c
5460 to periodically purge the ID Cache.
5462 * Fixed INFO command in the server. It works now in router
5463 environment. Added <server name> argument to the INFO command
5464 reply. Updated the protocol specs.
5466 * Fixed minor bug in silc_idcache_purge to not purge if the
5467 expire value is zero.
5469 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5470 they were buggy because of the WHOWAS information.
5472 * Fixed local command MSG to handle the async resolving of
5473 the remote client properly. It used to fail the first MSG.
5474 Affected file silc/local_command.c.
5476 * Added `data_len' field to SilcIDCache context.
5478 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Update TODO. Todo in commands in the server.
5482 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5485 used by routers as broadcast packet to inform other routers
5486 about the changed user mode.
5488 Implemented the notify handling in the server. Affected file is
5489 silcd/packet_receive.c. Added the function
5490 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5492 * Added new generic Channel Payload and deprecated the New Channel
5493 Payload. The New Channel Payload is now the generic Channel
5496 * Added new argument `mode' to the silc_server_send_new_channel
5497 as it is required in the Channel Payload now.
5499 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5500 and created a new and real SilChannelPayload to represent the
5501 new generic Channel Payload. Implemented the encode/decode
5502 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5504 * Added silc_server_get_client_channel_list to return the list
5505 of channels the client has joined for WHOIS command reply.
5506 Affected file silcd/server.[ch].
5508 * Implemented the channel list sending in the WHOIS command reply
5509 in server and in the client.
5511 Implemented the channel list displaying on the user interface
5512 as well. Affected file silc/client_ops.c.
5514 * Added silc_channel_payload_parse_list to parse list of Channel
5515 Payloads. It returns SilcDList list of SilcChannelPayloads.
5516 Client for example can use this function to parse the list of
5517 channels it receives in the WHOIS command reply. The caller
5518 must free the list by calling silc_channel_payload_list_free.
5519 Affected files lib/silccore/silcchannel.[ch].
5521 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Added one new argument <user mode> to the WHOIS command reply
5524 to return the mode of the user in SILC. Updated the protocol
5527 Implemented it to the server and client.
5529 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Fixed the mode printing on the user interface on joining.
5532 Affected file silc/client_ops.c.
5534 * Implemented the UMODE command and user modes in general to the
5535 client library and to the user interface.
5537 * Implemented the UMODE command to the server.
5539 * The server now sends UNKNOWN_COMMAND error status if client sends
5540 unknown command. Affected file silcd/command.c.
5542 * All server commands now handle the command identifier the right
5543 way when sending the command reply to the client. The client can
5544 use to identify the command replies with the identifier.
5546 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Added silc_server_get_client_route to resolve the route to
5549 the client indicated by the client ID. Affected file is
5552 * Added silc_server_relay_packet as general function to relay
5553 packet to arbitrary destination. This deprecates functions
5554 like _send_private_message_key, _relay_notify etc. Affected
5555 file is silcd/packet_send.[ch].
5557 Removed silc_server_send_key_agreement,
5558 silc_server_send_private_message_key and
5559 silc_server_packet_relay_notify functions from the file
5560 silcd/packet_send.[ch].
5564 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5565 server. Affected file silcd/packet_receive.[ch].
5567 * Implemented the KILL command to the client. Implemented the
5568 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5569 Affected files lib/silcclient/command[_reply].c and
5570 lib/silcclient/client_notify.c. Implemented the KILL notify
5571 printing in the user inteface.
5573 * Fixed a lot silc_parse_nick memory leaks from the client
5574 library in the file lib/silcclient/command.c.
5576 * Changed the silc_server_send_notify_on_channels's `sender'
5577 argument from SilcSocketConnection to SilcClientEntry to
5578 check the sender as entry and not as connection object and not
5579 to send to the client provided as argument. The affected file
5580 is silcd/packet_send.[ch].
5582 * The notify packets that are destined directly to the client used
5583 to not to be processed by the server. Now changed that and the
5584 server processes all notify packets. After relaying the packet
5585 to the client the notify packet is processed in the server.
5587 * The silc_server_free_client_data now checks whether there is
5588 pending outgoing traffic for the client and purges the data to
5589 the network before removing the client entry.
5591 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5594 an client is killed from the SILC Network. Updated the protocol
5597 Added new function silc_server_send_notify_killed to the
5598 silcd/packet_send.[ch].
5600 * Added function silc_server_packet_relay_notify to relay notify
5601 packets that are destined directly to a client. In this case
5602 the server does not process the notify packets but merely relays
5603 it to the client. Affected file silcd/packet_send.[ch].
5605 Added also silc_server_packet_process_relay_notify to check
5606 whereto relay the notify. Affected file is
5607 silcd/packet_receive.[ch].
5609 * Implemented the KILL command to the server.
5613 * Added the backup schema desgined last fall to the protocol
5614 specs for everyone to see. The specification is in the
5615 *-spec-xx.txt draft and the packet type definitions for the
5616 backup routers is in *-pp-xx.txt draft. Thusly, added also
5617 new packet type SILC_PACKET_CELL_ROUTERS.
5619 * A big security problem in the implementation discovered. The
5620 signoff of an client did not cause new channel key generation
5621 which it of course should've done. The channel keys must be
5622 always re-generated when client leaves (or signoffs) the channel.
5623 The silc_server_remove_from_channels funtion now handles
5624 the channel key re-generation.
5626 * Added `sender' argument to the silc_server_send_notify_on_channels
5627 to not to send the client provided as argument. Affected file
5628 silcd/packet_send.[ch].
5630 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Implemented OPER and SILCOPER commands into the server and
5635 * Added silc_auth_verify and silc_auth_verify_data to verify
5636 the authentication directly from the authentication payload.
5637 It supports verifying both passphrase and public key based
5638 authentication. Affected file lib/silccore/silcauth.[ch].
5640 * Added `hash' field to the SilcIDListData structure. It is the
5641 hash negotiated in the SKE protocol. Affected file is
5644 * Slight redesigning of the SilcAuthPayload handling routines.
5645 Do not send SilcPKCS but SilcPublicKey as argument.
5647 * Implemented the public key authentication support to the
5648 serverconfig. The public key is loaded from the provided path
5649 and saved as authentication data to void * pointer. Thus,
5650 changed the unsigned char *auth_data to void *auth_data;
5652 * Fixed SHUTDOWN command to send the reply before the server
5653 is shutdown. :) Affected file silcd/command.c.
5655 * Fixed fatal bug in CONNECT command. The hostname was invalid
5656 memory and server crashed. Affected file silcd/command.c.
5658 * Fixed fatal bug in CLOSE command. The server_entry became
5659 invalid but was referenced later in the command. Affected file
5662 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Fixed fatal bug in failure packet handling. Server ignored
5665 the failure and thus crashed when it came.
5669 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5672 that the command may be executed only once in (about) 2 seconds.
5673 The old SILC_CF_LAG flag is same but allows command bursts up
5674 to five before limiting.
5676 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5677 server code. Various commands now includes the CF_LAG_STRICT
5678 flag to disallow any kind of miss-use of the command.
5680 * Fixed the silc_buffer_unformat to not to allocate any data
5681 if the length of the data is zero. It used to allocate the
5682 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5684 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Changed the format of AdminConnection configuration section
5687 in the server. Added username of the admin to the format.
5688 Affected files silcd/serverconfig.[ch].
5690 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5691 to return admin configuration data by host, username and/or
5694 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Implemented WHOWAS command to the server. Added the functions:
5698 silc_server_command_whowas_parse,
5699 silc_server_command_whowas_send_reply,
5700 silc_server_command_whowas_from_client and
5701 silc_server_command_whowas_from_server
5703 * Added <Client ID> argument to the WHOWAS command reply. Updated
5704 the protocol specs accordingly.
5706 * Implemented WHOWAS command and command_reply to the client
5709 Implemented the WHOWAS printing on the user interface.
5711 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Added new argument to the WHOWAS command reply, the real name.
5714 It is an optional argument. Updated the protocol specs.
5716 * Added SilcIDCacheDestructor callback that is registered when
5717 the SilcIDCache is allocated. The callback is called when
5718 an cache entry in the ID Cache expires, or is purged from the
5719 cache. Added into lib/silccore/idcache.[ch].
5721 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5722 to destruct the client entries when the cache entry expires.
5723 Other ID Cache's in server and in the client library ignores
5726 * If the ID Cache entry's `expire' field is zero then the entry
5727 never expires. Added boolean `expire' argument to the
5728 silc_idcache_add function in the lib/silccore/idcache.[ch].
5729 If it is TRUE the default expiry value is used.
5731 * Added silc_server_free_client_data_timeout that is registered
5732 when client disconnects. By default for 5 minutes we preserve
5733 the client entry for history - for WHOWAS command.
5735 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added support to the server to enforce that commands are not
5738 executed more than once in 2 seconds. If server receives
5739 commands from client more frequently, timeout is registered
5740 to process the commands. Affected file silcd/command.c.
5741 Added new function silc_server_command_process_timeout.
5743 * Changed NICK_NOTIFY handling in client library to check that
5744 if the client's nickname was changed, so there is no need to
5745 resolve anything from the server.
5747 * Removed error printing from the WHOIS and IDENTIFY commands.
5748 If error occurs then it is ignored silently in the client library.
5749 The application, however, may map the received error to
5750 human readable error string. The application currently maps
5751 the NO_SUCH_NICKNAME error to string.
5753 * Made the command status message public to the application. Moved
5754 them from lib/silcclient/command_reply.c to
5755 lib/silcclient/command_reply.h. The application can map the
5756 received command status to the string with the
5757 silc_client_command_status_message function.
5759 * Added check to the server to check that client's ID is same
5760 as the Source ID in the packet the client sent. They must
5763 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Added dist-bzip hook to the Makefile.am to make bzip2
5766 compressed distributions.
5768 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Server now enforces the maximum length for the nickname and
5771 the channel as protocol specification dictates. 128 bytes for
5772 nickname and 256 bytes for channel name.
5774 * Moved the WHOIS printing to the application. The client libary
5775 does not print out the WHOIS information anymore, the application
5776 must do it. Renamed silc_client_command_reply_whois_print to
5777 the silc_client_command_reply_whois_save.
5779 The client's idle time is also sent to the application now, and
5780 the idle is shown on screen.
5782 * Added silc_client_command_reply_identify_save to save the
5783 received IDENTIFY entries.
5785 * Do not check for channel private keys in message sending and
5786 reception if the channel does not have the PRIVKEY mode set.
5787 Affected file lib/silclient/client_channel.c.
5789 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5792 just surfaced after chaning the JOIN procedure.
5794 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * Added silc_client_get_clients_by_list to get client entries
5797 from Client ID list, that is returned for example by JOIN
5798 and USERS command replies. The application should use this
5799 function for example when JOIN command reply is received to
5800 resolve the clients already on the channel (library does not
5801 do that anymore as USERS command reply is not used in the JOIN
5802 procedure anymore). Affected files lib/silcclient/silcapi.h and
5803 lib/silcclient/idlist.c.
5805 * JOIN command reply and USERS command reply returns now SilcBuffer
5806 pointers instead of unsigned char pointers when returning
5807 the client list and mode list.
5809 * Added <Client ID> argument to the JOIN command reply, mainly
5810 for the server to identify for which client the command was
5811 originally sent. Updated protocol specs accordingly.
5813 * Added SilcDlist private_key pointer to the SilcChannelEntry
5814 in the client to support the channel private keys. Affected
5815 file is lib/silcclient/idlist.h.
5817 * Added SilcChannelPrivateKey argument to the function
5818 silc_client_send_channel_message so that application can choose
5819 to use specific private ke if it wants to. If it is not provided,
5820 the normal channel key is used, unless private keys are set.
5821 In this case the first (key that was added first) is used
5822 as the encryption key.
5824 * Implemented the support for channel private key handling.
5825 Implemented the following functions:
5827 silc_client_add_channel_private_key,
5828 silc_client_del_channel_private_keys,
5829 silc_client_del_channel_private_key,
5830 silc_client_list_channel_private_keys and
5831 silc_client_free_channel_private_keys
5833 Affected file lib/silcclient/client_channel.c.
5835 * Added the support for the private keys in the channel message
5836 sending and encryption and in the message reception and
5837 decryption. Affected funtions are
5838 silc_client_send_channel_message and silc_client_channel_message.
5840 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Added SKE's key verify callback to the client library's
5843 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5845 * Removed the statement that server (or router) must send USERS
5846 command reply when joining to the channel so that the client
5847 knows who are on the channel. Instead, the client list and
5848 client's mode list is now sent in the JOIN command reply to the
5849 client who joined channel. This is better solution.
5851 * Added function silc_server_get_users_on_channel and function
5852 silc_server_save_users_on_channel to the silcd/server.[ch].
5854 * Removed function silc_server_command_send_users from the
5857 * Do not show topic on the client library anymore. The topic is
5858 sent in the command reply notify to the application and the
5859 application must show the topic now.
5861 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Added client searching by nickname hash into the IDENTIFY and
5864 WHOIS commands in the server as they were clearly missing from
5865 them. Affected file is silcd/command.c.
5867 * Fixed a bug in private message receiving in the client library.
5868 The remote ID was freed and it wasn't supposed, now it is
5871 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Minor fix to the channel payload; allocate the data area, as it
5874 needs to be of specific length.
5876 * If the key agreement port is zero then the operating
5877 system will define the bound port. Affected files are
5878 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5880 * Added new function silc_channel_payload_decrypt into the file
5881 lib/silccore/silcchannel.[ch].
5883 * Moved the channel message etc, check from silc_packet_decrypt
5884 to applications. The library calls now a generic
5885 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5886 when the packet is either normal or special. This was done to
5887 allow more wide range of checking that was not allowed when
5888 the code was in library. Now applications can do virtually any
5889 checks to the packet and return to the library the decision how
5890 the packet should be processed. Affected files are
5891 lib/silccore/silcpacket.[ch].
5893 Added silc_server_packet_decrypt_check to the server and
5894 silc_client_packet_decrypt_check to the client library.
5896 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5897 to send with specified source and destination information.
5899 * Channel message delivery between routers was broken after the
5900 channel key distribution was fixed earlier. The channel key
5901 was used be to distributed to other routers as well which is not
5902 allowed by the protocol. Now this is fixed and channel keys
5903 really are cell specific and the channel message delivery between
5904 routers comply with the protocol specification.
5906 * Fixed various commands in server to check also the global list
5907 for the channel entry and not just the local list. The affected
5908 file silcd/command.c.
5910 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Added assert()s to buffer formatting and unformatting routines
5913 to assert (if --enable-debug) when error occurs. Affected
5914 file: lib/silcutil/silcbuffmt.c.
5916 * Changed to auto-reconnect to check whether the remote host is
5917 router and register the re-connect timeout if it is. It used
5918 to check that whether we are normal server, but router must do
5919 auto-reconnect with another router as well. Affected file
5922 * Removed the [<key len>] option from CMODE command as the cipher
5923 name decides the key length, nowadays. See the defined ciphers
5924 from the protocol specification.
5926 * Added [<hmac>] option to the CMODE command to define the HMAC
5927 for the channel. Added SILC_CMODE_HMAC channel mode.
5929 * Added [<hmac>] option for the JOIN command so that user can
5930 select which HMAC is used to compute the MACs of the channel
5933 * Added Hmac field to the Channel Message Payload. The integrity
5934 of plaintext channel messages are now protected by computing
5935 MAC of the message and attaching the MAC to the payload. The
5936 MAC is encrypted. Now, it is clear that this causes some
5937 overhead to the size of the packet but rationale for this is that
5938 now the receiver can verify whether the channel message decrypted
5939 correctly and also when private keys are set for the channel the
5940 receiver can decrypt the packet with several keys and check from
5941 the MAC which key decrypted the message correctly.
5943 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5944 lib/silccrypt/silccipher.[ch].
5946 * Added silc_hash_len to return the digest length into the
5947 lib/silcrypt/silchash.[ch].
5949 * Rewrote parts of Silc Channel Payload interface in the
5950 lib/silccore/silcchannel.[ch]. The encode function now also
5951 encrypts the packet and parse function decrypts it.
5953 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Fixed a minor formatting bug in the SKE's key material processing.
5956 It actually might have processed the keys wrong way resulting
5959 * Redefined the mandatory HMAC algorithms and added new algorithms.
5960 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5961 and hmac-md5 truncated to 96 bits. The mandatory is now
5962 hmac-sha1-96. Rest are optional (including the one that used
5963 to be mandatory). Rationale for this is that the truncated HMAC
5964 length is sufficient from security point of view and can actually
5965 make the attack against the HMAC harder. Also, the truncated
5966 HMAC causes less overhead to the packets. See the RFC2104 for
5969 * Added new [hmac] configuration section. The SKE used to use
5970 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5971 is of course wrong. The official names that must be proposed in
5972 the SKE are the ones defined in the protocol specification
5973 (hmac-sha1-96 for example). The user can configure any hmac
5974 using any hash function configured in the [hash] section. At
5975 least, the mandatory must be configured.
5977 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5979 * Added HMAC list to the SKE proposal list. It has now both
5980 hash algorithm list and HMAC list. This makes the protocol
5981 incompatible with previous versions. The SKE now seems to work
5982 the way it is supposed to work, for the first time actually.
5984 * Defined plain Hash algorithms to the protocol specification.
5987 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Implemented support for key agreement packets into the server.
5990 Added functions silc_server_key_agreement and
5991 silc_server_send_key_agreement. Other than these functions,
5992 server has nothing to do with this packet.
5994 * Added support for private message key packets into the server.
5995 Added functions silc_server_private_message_key and
5996 silc_server_send_private_message_key.
6000 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6001 called in the protocol's final callback instead in the END
6002 protocol state. This makes a little more sense and in the same
6003 time in client we can use the same protocol routines for normal
6004 key exchange and to key agreement packet handling as well.
6006 * Added to both client's and server's KE protocol context the
6007 SilcSKEKeyMaterial pointer to save the key material. We will
6008 bring the key material to the protocol's final callback by doing
6009 this. The final callback must free the key material.
6011 * Added SKE's packet_send callback into client's KE protocol
6012 context so that the caller can choose what packet sending function
6013 is used. This way we can use different packet sending when
6014 doing normal SKE when doing key agreement packet handling (in
6015 the key agreement packet handling we do not want to encrypt
6018 * Implemented the responder side of the key agreement routines
6019 in the client. The client can now bind to specified port and
6020 accept incoming key negotiation. The key material is passed
6021 to the application after the protocol is over.
6023 * Implemented the processing of incoming Key Agreement packet
6024 in the client. Added function silc_client_key_agreement to
6027 * Implemented the intiator side of the key agreement routines
6028 in the client. The client can now initiate key agreement with
6029 another remote client. The key material is passed to the
6030 application after the protocol is over.
6032 * Created client_keyagr.c to include all the key agreement
6035 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6036 SILC_TASK_CALLBACK except that it is not static.
6038 * Created client_notify.c and moved the Notify packet handling
6039 from the client.[ch] into that file.
6041 * Created client_prvmsg.c and moved all private message and
6042 private message key routines from the client.[ch] into that file.
6044 * Create client_channel.c and moved all channel message and
6045 channel private key routines from the client.[ch] into that file.
6047 * Changed silc_client_get_client_by_id_resolve to resolve with
6048 WHOIS command instead of IDENTIFY command, in the file
6049 lib/silclient/idlist.c.
6051 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Implemented the SKE's responder side to the Client library.
6055 * When FAILURE is received to the protocol do not trust it
6056 blindly. Register a timeout to wait whether the remote closes
6057 the connection as it should do it, only after that process the
6058 actual failure. This was changed to both client and server.
6060 * Added client_internal.h to include some of the structures
6061 there instead of client.h in lib/silcclient/.
6063 * Added function silc_task_unregister_by_callback to unregister
6064 timeouts by the callback function.
6066 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Some "Incomplete WHOIS info" errors has been appearing on the
6069 log files. Took away the entry->userinfo check from WHOIS
6070 reply sending. The entry->userinfo is now " " if client did not
6071 provide one. I thought this was fixed earlier but something
6072 is wrong still. Let's see if the error still appears.
6074 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Fixed a minor bug in the login when the channel key is
6077 re-generated in the server. It used to generate the key in
6078 wrong order and thus caused problems in the channel traffic.
6080 * Fixed a minor bug in channel key distsribution after
6081 KICK command. The key was not sent to the router even though
6084 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Added silc_ske_process_key_material_data as generic routine
6087 to process any key material as the SILC protocol dictates. The
6088 function is used by the actual SKE library but can be used by
6089 applications as well. This relates to the private message keys
6090 and the channel private keys since they must be processed the
6091 same way the normal SILC session keys. The protocol dictates
6092 this. Affected files: lib/silcske/silcske.[ch].
6094 Added also silc_ske_free_key_material to free the
6095 SilcSKEKeyMaterial structure.
6097 * Defined silc_cipher_set_key function to set the key for
6098 cipher without using the object's method function. The affected
6099 files: lib/silccrypt/silccipher.[ch].
6101 * Implemented silc silc_client_add_private_message_key,
6102 silc_client_add_private_message_key_ske,
6103 silc_client_del_private_message_key,
6104 silc_client_list_private_message_keys and
6105 silc_client_free_private_message_keys functions in the
6108 Added functions silc_client_send_private_message_key to send
6109 the Private Message Key payload and silc_client_private_message_key
6110 to handle incoming Private Message Key payload.
6112 * Added Cipher field to the Private Message Key payload to set
6113 the cipher to be used. If ignored, the default cipher defined
6114 in the SILC protocol (aes-256-cbc) is used.
6116 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Removed lib/silcclient/ops.h file.
6120 Redefined parts of the SILC Client Library API. Created new
6121 file silcapi.h that deprecates the ops.h file and defines the
6122 published Client Library API. Defined also private message key
6123 API and channel private key API into the file.
6125 This is the file that the application must include from the
6126 SILC Client Library. Other files need not be included by
6127 the application anymore.
6129 * Added new key_agreement client operation callback and also
6130 defined the Key Agreement library API for the application.
6132 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6135 is used by clients to request key negotiation between another
6136 client in the SILC network. If the negotiation is started it
6137 is performed using the SKE protocol. The result of the
6138 negotiation, the secret key material, can be used for example
6139 as private message key.
6141 Implemented the Key Agreement payload into the files
6142 lib/silccore/silauth.[ch].
6144 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Redefined ciphers for the SILC protocol. Added some new ciphers
6147 and defined the key lengths for the algorithms. Changed the
6148 code accordingly. The default key length is now 256 bits.
6150 * Fixed SKE key distribution function silc_ske_process_key_material
6151 when the key length is more than 128 bits. The default key
6152 length in SILC is now 256 bits.
6154 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6155 to indicate unsupported algorithm.
6157 * Renamed rijndael.c to aes.c and all functions as well.
6159 * Fixed a long standing channel key setting bug in client library.
6160 Weird that it has never surfaced before.
6162 * Fixed bug in channel deletion. If the entire channel is removed
6163 then it must also delete the references of the channel entry
6164 from the client's channel list as the client's channel entry and
6165 the channel's client entry share same memory.
6167 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Implemented CONNECT and SHUTDOWN commands in the client.
6171 * Implemented CLOSE command to the client.
6173 * Added the function silc_idlist_find_server_by_name into the
6174 files silcd/idlist.[ch].
6176 Added the function silc_idlist_find_server_by_conn into the
6177 files silcd/idlist.[ch].
6179 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * DIE command was renamed to SHUTDOWN. Updated the both code
6184 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6185 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6187 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6190 * Added function silc_server_create_connection function to create
6191 connection to remote router. My server implementation actually
6192 does not allow router to connect to normal server (it expects
6193 that normal server always initiates the connection to the router)
6194 so the CONNECT command is only good for connecting to another
6197 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6200 or some other client was kicked from the channel.
6202 Implemented the handling of the notify type to both client
6205 Implemented silc_server_send_notify_kicked to send the KICKED
6206 notify. It is used to send it to the server's primary router.
6208 * Implemented the KICK command into server and client.
6210 * Added `query' argument to the silc_idlist_get_client function
6211 to indicate whether to query the client from server or not if
6214 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6215 to indicate that the client is not channel founder.
6219 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Removed the rng context from SilcPacketContext structure and
6222 changed that the packet routine uses the Global RNG API.
6224 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Added support for quit message that client can "leave" on the
6227 channel when it quits the SILC. It is ditributed inside the
6228 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6230 Added silc_server_free_client_data that will take the
6231 signoff message as argument.
6233 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6235 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Updated parts of the protocol specification to keep it up
6240 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6243 payloads in one packet.
6245 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6246 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6247 use now the new List flag.
6249 * Also deprecated the following packet types: REPLACE_ID,
6250 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6252 * Added list support for Notify packet in server.
6254 * Added silc_server_send_notify_channel_change to send the
6255 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6256 the silc_server_send_replace_id.
6258 * Added silc_server_send_notify_nick_change to send the
6259 NICK_CHANGE notify type. Deprecates the function
6260 silc_server_send_replace_id.
6262 * Added silc_server_send_notify_join to send the JOIN notify type.
6263 Deprecates the function silc_server_send_new_channel_user.
6265 * Added silc_server_send_notify_leave to send LEAVE notify type.
6266 Deprecates the function silc_server_send_remove_channel_user.
6268 * Added silc_server_send_notify_cmode and
6269 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6270 types. Deprecates the silc_server_send_set_mode function.
6272 * Added SERVER_SIGNOFF notify type to indicate that server has
6273 quit. This means that all clients on the channel from that
6274 server will drop. This can be also used when netsplit happens.
6276 Deprecated REMOVE_ID packet type since it is not needed anymore
6279 Added silc_server_send_notify_server_signoff to send the
6280 SERVER_SIGNOFF notify type. Deprecates the function
6281 silc_server_send_remove_id.
6283 Added also silc_server_send_notify_signoff to send the
6284 SIGNOFF notify type.
6286 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6287 SILC protocol from this day on. Changed the protocol
6288 specification as well.
6290 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6291 notify type. It is used between routers to notify about
6292 topic changes on a channel.
6294 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6297 * Partly updated the protocol specification to comply with the
6298 changes now made. It is still though a bit outdated.
6300 * The JOIN notify type now takes one extra argument <Channel ID>.
6301 The packet used to be destined to the channel but now the
6302 JOIN type may be sent as list thus it is impossible to
6303 destine it to any specific channel. By adding this argument
6304 it is again possible.
6306 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Added CREDITS file. The CHANGES and CREDITS file will appear
6309 in the distribution as well.
6311 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6314 types in the server's silcd/packet_receive.c.
6316 * Implemented CMODE and CUMODE to work in router environment.
6318 * Fixed minor encoding and decoding buglet from the
6319 lib/silccore/silcmode.c.
6321 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6324 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6326 * Changed all SilcConfigServer* and silc_config_server* to
6327 SilcServerConfig* and silc_server_config*, respectively.
6330 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Associated the ID (client or server ID) to the Authentication
6333 Payload to avoid any possibility of forging. Updated the
6334 protocol specification and the code accordingly.
6336 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * The RSA key length is now save to the RsaKey context in the
6339 key generation process in lib/silccrypt/rsa.c. The key length
6340 is now used to figure out the maximum size of the block allowed
6341 to be encrypted/signed.
6343 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6344 is equivalent to the silc_mp_mp2bin but does not allocate any
6347 * Changed silc_mp_mp2bin API to take length argument. If it is
6348 non-zero then the buffer is allocated that large. If zero, then
6349 the size is approximated using silc_mp_sizeinbase, which however
6352 * Created Global RNG API which is global RNG that application can
6353 initialize. After initializing, any routine anywhere in the
6354 code (including library) can use RNG without allocating a new
6355 RNG object. This was done to allow this sort of use of the
6356 RNG in code that has no chance to allocate RNG object. All
6357 applications currently allocate this and many routines in the
6358 library use this. Affected file lib/silccrypt/silcrng.[ch].
6360 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6361 it to use the Global RNG API.
6363 * Defined Authentication Payload into protocol specification that
6364 is used during SILC session to authenticate entities. It is
6365 used for example by client to authenticate itself to the server
6366 to obtain server operator privileges.
6368 Implemented this payload into the lib/silccore/silcauth.[ch].
6369 Implemented also routines for public key based authentication
6370 as the new protocol specification dictates.
6372 Moved definitions of different authentication methods from
6373 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6375 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6376 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6377 silc_pkcs_verify_with_hash functions into the file
6378 lib/silccrypt/silcpkcs.[ch].
6380 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * The client entry's userinfo pointer must be always valid.
6383 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6384 will fail since it requires the userinfo. Now, the userinfo
6385 is allocated as "" if actual userinfo does not exist. Actually,
6386 it must exist and it is totally Ok to drop client connections
6387 that does not announce the userinfo. However, we will make
6388 this workaround for now.
6390 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6391 to return the remote port by socket.
6393 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6396 SILC_SERVER_PENDING_EXEC and added an new macro
6397 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6398 data or when error occurs while processing the pending command.
6400 Added new argument `destructor' into silc_server_command_pending
6401 and to the SilcServerCommandPending object. This destructor is
6402 now called after calling the pending callback or if error occurs
6403 immediately. If error occurs the actual pending callback won't
6404 be called at all - only the destructor. The destructor may be
6405 NULL if destructor is not needed.
6407 All this applies for client library code as well. Similar
6408 changes were made there as well for the pending commands.
6410 In the client, the application must now allocate the
6411 SilcClientCommandContext with the silc_client_command_alloc
6414 * Added reference counter to the SilcServerCommandContext. Added
6415 function silc_server_command_alloc and silc_server_command_dup
6418 Same type of functions added to the client library for the same
6421 * Removed the cmd_ident from IDListData away since it is now
6422 global for all connections. It is the command identifier used
6423 in command sending and with pending commands. The affected file
6426 * Added reference counter to the SilcSocketConnection objecet to
6427 indicate the usage count of the object. The object won't be
6428 freed untill the reference counter hits zero. Currently only
6429 server uses this, and client ignores it. The client must be
6430 set to use this too later. The affected files are
6431 lib/silccore/silcsockconn.[ch]. Added also the function
6432 silc_socket_dup to increase the reference counter.
6434 This was mainly added because it is possible that the socket
6435 is removed underneath of pending command or other async
6436 operation. Now it won't be free'd and proper DISCONNECTING
6437 flags, etc. can be set to avoid sending data to connection that
6438 is not valid anymore.
6440 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6441 the connection. After that it sets SILC_SET_DISCONNECTED.
6442 It is, however, possible that the socket data is not still freed.
6443 The silc_server_packet_process now checks that data is not
6444 read or written to connection that is DISCONNECTED. The socket
6445 get's freed when the reference counter hits zero.
6447 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6449 * Changed the client operation API: channel_message operation's
6450 `sender' is now the client entry of the sender, not the nickname
6451 and the `channel' is the channel entry, not the channel name.
6453 In the private_message operation the `sender' is now also the
6454 client entry of the sender not the nickname.
6456 Affected file is lib/silcclient/ops.h and all applications
6457 using the client operations.
6459 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Moved the calling of ops->connect() from connect_to_server_final
6462 into receive_new_id functin since that is the point when the
6463 client is actually allowed to send traffic to network. The
6464 affected file is lib/silcclient/client.c.
6466 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6469 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6470 (if needs broadcasting) instead of broadcasting the packets one
6471 by one which would make a burst in the network traffic.
6473 * Added `broadcast' argument to the functions in silcd/server.[ch]
6474 silc_server_create_new_channel[_with_id] to indicate whether
6475 to send New Channel packet to primary router.
6477 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * Added new function into the silcd/server.[ch] files:
6480 silc_server_create_new_channel_with_id to create new channel with
6481 already existing Channel ID.
6483 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6484 lib/silccore/silcpacket.h. This packet is used t send list of
6485 Set Mode payloads inside one packet. Server uses this to set
6486 the modes for the channels and clients on those channels, that it
6487 announced to the router when it connected to it. The protocol
6488 specification has been updated accordingly.
6490 * The silc_server_new_channel did not handle the packet coming
6491 from normal server as it normally does not send that. However,
6492 when it announces its channels it does send it. Implemented
6493 the support for that.
6495 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6496 into the file lib/silccore/id.h.
6498 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Fixed memory leaks in the functions silc_idlist_del_client,
6501 silc_idlist_del_channel and silc_idlist_del_server in the file
6502 silcd/idlist.c. All of those leaked like a sieve.
6504 * Fixed some small memory leaks in the client's function
6505 silc_client_notify_by_server.
6507 * Added functions into silcd/server.c: silc_server_announce_clients,
6508 silc_server_announce_channels and silc_server_announce_server.
6509 These functions are used by normal and router server to announce
6510 to its primary router about clients, channels and servers (when
6511 router) that we own. This is done after we've connected to the
6514 These functions effectively implements the following packet types:
6515 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6516 and SILC_PACKET_NEW_ID_LIST.
6518 * Added new functions into the silcd/packet_receive.[ch]:
6519 silc_server_new_id_list, silc_server_new_channel_list and
6520 silc_server_new_channel_user_list to handle the incoming
6521 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6523 * Added support of changing Channel ID in the function
6524 silc_server_replace_id. If the server that announces a channel
6525 to the router already exists in the router (with same name but
6526 with different Channel ID), router is responsible to send
6527 Replace ID packet to the server and force the server to change
6528 the Channel ID to the one router has.
6530 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6531 client that the Channel ID has been changed by the router. The
6532 normal server sends this to the client. Client must start using
6533 the new Channel ID as the channel's ID.
6535 Implemented handling of this new type into lib/silcclient/client.c
6536 into the function silc_client_notify_by_server.
6538 * Added new function silc_idlist_replace_channel_id into the files
6539 silcd/idlist.[ch] to replace the Channel ID.
6541 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Call silc_server_command_identify_check always when processing
6544 the IDENTIFY command in silcd/command.c
6546 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6548 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6549 send keepalive packets. The packet can be sent by clients,
6550 servers and routers.
6552 Added function silc_socket_set_heartbeat into the file
6553 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6554 If not set, the heartbeat is not performed. The actual
6555 heartbeat is implemented in the low level socket connection
6556 library. However, application is responsible of actually
6559 Added silc_server_send_heartbeat to send the actual heartbeat
6560 packet into silcd/packet_send.[ch]. Server now performs
6561 keepalive with all connections.
6563 * Added silc_task_get_first function into lib/silcutil/silctask.c
6564 to return the timeout task with shortest timeout. There was a bug
6565 in task unregistration that caused problems. TODO has been
6566 updated to include that task system must be rewritten.
6568 * The client library will now resolve the client information when
6569 receiving JOIN notify from server for client that we know but
6570 have incomplete information.
6572 * Rewrote parts of silc_server_remove_from_channels and
6573 silc_server_remove_from_one_channel as they did not remove the
6574 channel in some circumstances even though they should've.
6576 * Encryption problem encountered in server:
6578 The LEAVE command used to send the Channel Key packet to the
6579 router immediately after generating it. However, the code
6580 had earlier sent Remove Channel user packet but not immediately,
6581 ie. it was put to queue. The order of packets in the router
6582 was that Channel Key packet was first and Remove Channel User
6583 packet was second, even though they were encrypted in the
6584 reverse order. For this reason, MAC check failed. Now, this
6585 is fixed by not sending the Channel Key packet immediately but
6586 putting it to queue. However, this is more fundamental problem:
6587 packets that are in queue should actually not be encrypted
6588 because packets that are sent immediately gets encrypted
6589 actually with wrong IV (and thus MAC check fails). So, packets
6590 that are in queue should be encrypted when they are sent to
6591 the wire and not when they put to the queue.
6593 However, the problem is that the current system has not been
6594 designed to work that way. Instead, the packet is encrypted
6595 as soon as possible and left to the queue. The queue is then
6596 just purged into wire. There won't be any fixes for this
6597 any time soon. So, the current semantic for packet sending
6600 o If you send packet to remote host and do not force the send
6601 (the packet will be in queue) then all subsequent packets to the
6602 same remote host must also be put to the queue. Only after the
6603 queue has been purged is it safe again to force the packet
6606 o If you send all packets immediately then it safe to send
6607 any of subsequent packets through the queue, however, after
6608 the first packet is put to queue then any subsequent packets
6609 must also be put to the queue.
6611 Follow these rules and everything works fine.
6613 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Added new function silc_server_remove_clients_by_server to
6616 remove all client entries from ID list when the server connection
6617 is lost. In this case it is also important to invalidate all
6618 client entires as they hold the invalid server entry. This
6619 fixes fatal bug when server has lost connection and will reconnect
6622 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Made some sanity checks to silc_server_daemonise like to check
6625 whether the requested user and group actually exists.
6627 * Added sanity check to SKE's silc_ske_responder_finish to check
6628 that the public and private key actually is valid.
6630 * Invalidate the client's nickname when receiving Replace ID
6631 packet and the Client ID is being replaced. This means that the
6632 server will query the nickname if someone needs it (client)
6635 * Sort the ID Cache in client library when the ID Cache data
6636 has changed (needs sorting).
6638 * Do not allow for SILC client to create several connections to
6639 several servers. The client does not support windows right now
6640 and generating multiple connections causes weird behaviour.
6642 Irssi-silc client does support windows and can handle several
6643 connections without problems, see: www.irssi.org and SILC plugin.
6645 * Fixed some places where client was added to the IDList. The
6646 rule of thumb is following (in order to get everything right):
6647 If the client is directly connected local client then the
6648 `connection' argument must be set and `router' argument must be
6649 NULL to silc_idlist_add_client function. If the client is not
6650 directly connected client then the `router' argument must
6651 bet set and the `connection' argument must be NULL to the
6652 silc_idlist_add_client function.
6654 * The funtion silc_server_packet_send_local_channel actually did
6655 not check whether the client was locally connected or not. It
6656 does that now. Fixed a bug related to LEAVE command.
6658 * Fixed Remove Channel User payload parsing bug in server's
6659 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6661 * The server's silc_server_save_channel_key now checks also the
6662 global ID list for the channel as it might not be in the local
6663 list. Fixed a bug related to LEAVE command.
6665 * Is this the end of the [<unknown>] buglet that has been lurking
6666 around for a long time? A little for loop fix in server's
6667 silc_server_command_whois_parse that is used by both IDENTIFY
6668 and WHOIS command. At least, this was a clear bug and a cause
6669 of one type of [<unknown>] buglet.
6671 * WHOIS and IDENTIFY commands call the function
6672 silc_server_command_[whois/identify]_check function even if
6673 we are not router server.
6675 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6677 * Added --with-gmp configuration option. If set the GMP
6678 is always compiled in the SILC source tree. If not set then
6679 it is checked whether the system has the GMP3 installed. If
6680 it has then the GMP won't be compiled (the system's headers
6681 and library is used), if it doesn't have it then the GMP is
6682 compiled in the SILC source tree.
6684 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Changed RSA private exponent generation to what PKCS #1
6687 suggests. We try to find the smallest possible d by doing
6688 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6689 not security fix but optimization.
6691 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6693 * Added new config entry [Identity] to fork the server and run
6694 it as specific user and group. A patch from Bostik.
6696 * Imported Dotconf configuration library into lib/dotconf.
6697 This will be used to create the SILC configuration files later.
6698 It will appear in the distsribution after this commit.
6700 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * A big code auditing weekend happening. Auditing code for
6703 obvious mistakes, bugs and errors. Also, removing any code
6706 Removed files for being obsolete:
6708 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6709 inline in the file lib/silcutil/silcbuffer.h)
6711 o lib/silcutil/silcbufutil.c (the header has inline versions)
6713 Changed code to fix possible error conditions:
6715 o The buffer formatting routines now check that the destination
6716 buffer really has enough space to add the data. This applies for
6717 both buffer formatting and unformatting
6718 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6719 unformatting was changed to accomodate following rules:
6720 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6721 sent to the function while XXX_*STRING will not allocate or copy
6722 the data into the buffer. Instead it sets the pointer from the
6723 buffer into the pointer sent as argument (XXX_*STRING used to
6724 require that the pointer must be allocated already). This change
6725 makes this whole thing a bit more consistent and more optimized
6726 (note that the data returned in the unformatting with XXX_*STRING
6727 must not be freed now). The routines return now -1 on error.
6729 o Tried to find all code that use buffer_format and buffer_unformat
6730 and added return value checking to prevent formatting and
6731 especially unformatting errors and possible subsequent fatal
6734 o Changed ske->x and ske->KEY to mallocated pointers in
6735 lib/silcske/silcske.h. Fixed possible data and memory leak.
6737 o Added return value checking to all *_parse* functions. Fixed
6738 many memory leaks as well.
6740 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6741 so that buffer overflows would not happen. All code now also
6742 checks the return value as it can fail.
6744 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Added reconnection support to server if the normal server looses
6747 its connection to the router (for example if router is rebooted).
6748 The server performs normal reconnection strategy implemented
6749 to the server. Affected file silcd/server.c.
6751 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Added new packet type SILC_PACKET_SET_MODE that is used to
6754 distribute the information about changed modes (for clients,
6755 channels and clients channel modes) to all routers in the
6756 network. Updated the protocol specification accordingly.
6758 Added functions into silcd/packet_send.c and
6759 silcd/packet_receive.c: silc_server_send_set_mode,
6760 silc_server_set_mode.
6762 Added new files silcmode.[ch] into lib/silccore that implements
6763 the encoding and decoding of Set Mode Payload. Added new type
6764 SilcSetModePayload. Moved the definitions of different modes
6765 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6767 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Oops, a little mistake in server's connection authentication
6770 protocol. The protocol is not ended with FAILURE but with
6771 SUCCESS if the authentication is Ok. :) Affected file is
6774 * Implemented NICK_CHANGE notify handling in server in the file
6775 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6776 the local clients on the channel. After the changing nickname
6777 in router environment snhould work and the [<unknown>] nickname
6778 should appear no more.
6780 The silc_server_replace_id function that receives the Replace ID
6781 payload now sends the NICK_CHANGE notify type also in the file
6782 silcd/packet_receive.c
6784 * Changed WHOIS and IDENTIFY command to support the maximum amount
6785 of arguments defined in protocol specs (3328 arguments). This
6786 fixed a bug that caused problems when there were more than three
6789 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Added extra parameter, command identifier, to the
6792 silc_client_send_command so that explicit command identifier
6795 Changed that ID list routines uses specific command identifier
6796 when sending WHOIS/IDENTIFY requests to the server so that they
6797 can be identified when the reply comes back.
6799 Affected files lib/silcclient/command.[ch],
6800 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6802 * Added `sender' argument to silc_server_packet_send_to_channel
6803 to indicaet the sender who originally sent the packet to us
6804 that we are now re-sending. Ignored if NULL. Affected file
6805 silcd/packet_send.[ch].
6807 * Added some server statistics support in silcd/server_internal.h
6808 SilcServerStatistics structure and around the server code. Also
6809 send some nice statistics information when client is connecting
6812 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Fixed channel ID decoding in server's JOIN command reply in
6815 silcd/command_reply.c
6817 * Fixed braodcasting of replace ID payload to not to send it if
6818 we are standalone server in silcd/packet_receive.c.
6820 * Fixed all channel message sending routines to not to send
6821 packets to clients that has router set, since they are routed
6822 separately in the same function earlier. Affects file
6823 silcd/packet_send.c and all channel packet sending functions.
6825 * In USERS reply, res_argv[i] are not allocated, the table
6826 is allocated. Thus changed that free the table, not its
6829 * In server's whois_check and identify_check if the client is
6830 locally connected do not send any WHOIS commands - they are not
6833 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Fixed some minor bugs in client when sending WHOIS command. The
6836 arguments was in wrong order.
6838 * Removed statis function add_to_channel from server in
6839 silcd/command.c that was previously used with the joining but
6842 * Tested USERS command in router environment successfully with two
6843 routers, two servers and two clients.
6845 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Reorganized the USERS command and command reply in client library
6848 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6849 When the command is given by user we register a pending command
6850 callback that will reprocess the command after the reply has been
6851 received from the server. When reprocessing the packet we then
6852 display the information. Thus, the USERS information is displayed
6853 now in the command callback instead of in the command reply
6854 callback. The processing of the command is same as previously
6855 when server has sent the command reply in the JOINing process.
6857 * Added to USERS command in silcd/command_reply.c to join the client,
6858 we didn't use to know about, to the channel after we've created
6859 a client entry for it. Also, for clienet we did know already still
6860 check whether it is on the channel or not and add it if not.
6862 * Removed silc_server_command_join_notify as the function and its
6865 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Changed the client's pending command handling to the same as the
6868 server's pending command handling. It is also now possible to
6869 execute command reply functions from other command reply
6870 function as the function callbacks for commands and command
6871 replies are one and same. The pending commands are not static
6872 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6873 in client connection context. Thus, pending commands are server
6874 connection specific as it is convenient.
6876 Changed the function silc_client_command_pending and
6877 silc_client_command_pending_del and added new function
6878 silc_client_command_pending_check. Removed the
6879 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6882 * Added cmd_ident, current command identifier, to the client
6883 connection context in lib/silcclient/client.h to keep track on
6884 command identifiers used in command sending. Client's command reply
6885 function handling now supports the mandatory command identifiers.
6887 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6888 funtions in client to fully support pending command callbacks.
6890 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6891 as one of the arguments to the application in the command reply
6894 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6895 before first releasing SILC but came back. Now it is removed again
6896 and should come back nomore. The FORWARDED flag was used only
6897 by the JOINing procedure by forwarding the command packet to router.
6898 Now, the JOINing procedure has been changed to more generic (due
6899 to various router environment issues) and FORWARDED is not needed
6900 anymore for anything. The protocol specification is yet to be
6903 Now, removed silc_server_packet_forward from server and the flag
6904 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6906 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Renamed NAMES command to USERS command. The NAMES was named that
6909 due to historical reasons. Now it is renamed. Also, rewrote
6910 parts of the USERS command. The nickname list is not sent anymore
6911 by the server. Only Client ID and mode lists are sent in the USERS
6912 command. Changed this also to the protocol specification.
6914 The client now resolves the names and stuff after it receives
6915 the USERS list from the server when joining to the channel.
6917 * WHOIS and IDENTIFY commands has been changed to support multiple
6918 Client ID's per command. One can now search for multiple users
6919 in the network by sending only one WHOIS or IDENTIFY command.
6920 Changed the code and the protocol specifications.
6922 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6923 uses silc_server_command_whois_parse to parse the request. */
6925 * If normal server, do not parse the WHOIS and IDENTIFY requests
6926 before sending it to the router. Saves some time.
6928 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Fixed JOIN command on client library. Wrong number of arguments
6931 used to crash the client.
6933 * Added silc_server_channel_has_global function to check whether
6934 channel has global users or not.
6936 * Added silc_server_channel_has_local function to check whether channel
6937 has locally connected clients on the channel.
6939 * The silc_server_remove_from_one_channel now checks whether the
6940 channel has global users or not after given client was removed from
6941 the channel. It also checks whether the channel has local clients
6942 on the channel anymore. If it does not have then the channel entry
6943 is removed as it is not needed anymore.
6945 * The silc_server_notify now checks on JOIN notify whether the joining
6946 client is one of locally connected or global. If it is global then
6947 the channel has now global users on the channel and that is marked
6948 to the channel entry. Also, it now saves the global client to
6949 global list who is joining and JOINs it to the channel. This is
6950 for normal server, that is.
6952 Changed silc_server_send_notify_on_channel,
6953 silc_server_packet_relay_to_channel and
6954 silc_server_packet_send_to_channel check if we are normal server
6955 and client has router set (ie. global client) do not send the
6956 message to that client, as it is already routed to our router.
6958 * Implemented LEAVE notify type handling in silc_server_notify
6961 * Tested LEAVE command in router environment successfully. Tested
6962 with two routers, two servers and two clients.
6966 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6968 * Implemented SIGNOFF notify type handling in silc_server_notify
6971 * silc_server_remove_id now removes the client entry from all channels
6972 it has joined and thusly sends SIGNOFF notify type.
6974 * Rewrote the NAMES list generation in server by removing two excess
6975 loops. The lists are created now inside one loop.
6977 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * silc_server_remove_channel_user checks now also global list
6980 for channel and client.
6982 * silc_server_new_channel_user checks now both local and global
6983 list for channel and client. Fixed a bug in client id decoding.
6984 Used to decode wrong buffer.
6986 * silc_server_channel_message checks now both local and global
6987 list for channel entry.
6989 * Tested channel joining (hence JOIN) in router environment
6990 successfully. Tested with two routers, two servers and two
6993 * Tested channel message sending in router environment successfully.
6995 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * Added silc_server_save_channel_key into server.[ch] to save the
6998 received channel key in Channel Key payload processing. It is
6999 also used in JOIN command reply handling.
7001 Equivalent function silc_client_save_channel_key added into
7002 client.[ch] into client library.
7004 * Changed JOIN command reply to send information whether the channel
7005 was created or not (is existing already) and the channel key
7006 payload. Changed protocol specs accordingly.
7008 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7009 the request was sent by ID and not by nickname. Crashed on
7012 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7014 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7015 now correctly save the received data.
7017 * silc_server_free_sock_user_data now notifies routers in the
7018 network about entities leaving the network.
7020 At the same time implemented functions silc_server_remove_id
7021 and silc_server_send_remove_id to receive and send REMOVE_ID
7022 packets. The packet is used to notify routers in the network
7023 about leaving entities. The ID removed will become invalid in
7026 * Added function silc_idlist_del_server into server. Removes and
7027 free's server entry from ID list.
7029 * silc_server_private_message function now checks, if we are router,
7030 that the destination ID really is valid ID, naturally.
7032 * In router when NEW_ID packet is received (for new client) the
7033 hash of the Client ID is saved in the ID Cache but the
7034 client->nickname is set to NULL, instead of putting the hash
7037 IDENTIFY command now also checks that client->nickname must be
7038 valid. If it is not if will request the data from the server who
7039 owns the client. Added new function
7040 silc_server_command_identify_check.
7042 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7043 to set the command to already allocated Command Payload.
7045 * Tested private message sending in router environment with two
7046 routers, two servers and two clients. Fixed minor bugs and now
7049 * Fixed segfault from client's NAMES command. Used to crash if
7052 * Forwarded packets must not be routed even if it is not destined
7053 to the receiver. Changed server code comply with this.
7055 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Added `require_reverse_mapping' boolean value to ServerParams
7058 structure. If TRUE (not default) the server will require that
7059 the connecting host has fully qualified domain name.
7061 If the reverse mapping is not required and hostname could not be
7062 found the IP address is used as hostname.
7064 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * Implemented version string checking to both client and server.
7067 The check is incomplete currently due to the abnormal version
7068 strings used in development version of SILC.
7070 * Changed all command functions in server to use the new
7073 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Changed char *data to unsigned char *data in ID Cache system to
7076 support binary data as ID Cache data. Changed code to support
7077 binary data in lib/silccore/idcache.c.
7079 * Renamed silc_server_packet_relay_command_reply to
7080 silc_server_command_reply as it is normal packet receiving
7081 function. Rewrote the function to accept command replys for
7082 servers and not only for clients.
7084 * Mark remote router always as registered server if we are connecting
7085 to it. Otherwise, commands sent by the router to us are ignored.
7087 * All ID List find routines now returns the ID Cache Entry pointer
7088 as well if requested.
7090 * WHOIS command works now in router environment, tested with two
7091 routers, two servers and two clients.
7093 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7094 in router environment (as it is almost equivalent to WHOIS) but
7095 hasn't been tested thoroughly. Added new functions:
7097 silc_server_command_identify_parse
7098 silc_server_command_identify_send_reply
7099 silc_server_command_identify_from_client
7100 silc_server_command_identify_from_server
7102 * Disabled route cache adding because adding two different ID's with
7103 same IP replaces the old cache entry thus giving wrong route.
7104 The entry->router->connection is always the fastest route anyway
7105 so route cache may not be needed. Of course, new routes maybe
7106 established after receiving the ID when the entry->router->connection
7107 might not be anymore the most optimal.
7109 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Add route cache for received ID for fast routing.
7113 * Added silc_server_packet_route to route received packet on router
7114 that is not destined to us.
7116 * Renamed silc_server_get_route to silc_server_route_get.
7118 * Added id_string and id_string_len fields into SilcServer to
7119 include encoded ServerID for fast comparing without excess
7120 encoding of the ID's.
7122 * Cleaned up WHOIS command on server side. Added following static
7125 silc_server_command_whois_parse
7126 silc_server_command_whois_check
7127 silc_server_command_whois_send_reply
7128 silc_server_command_whois_from_client
7129 silc_server_command_whois_from_server
7131 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7132 arguments in command replies. All command functions should be
7133 updated to use this macro.
7135 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Minor typo fixes on command reply handling on server.
7139 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Added silc_server_command_add_to_channel internal routine to add
7142 the client to the channel after router has created the channel and
7143 sent command reply to the server.
7145 * Added generic silc_server_send_command to send any command from
7148 * Use static buffer with ID rendering instead of duplicating data.
7150 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Fixed a channel user mode bug when joining to a channel server gave
7153 everybody channel founder rights, oops.
7155 * We mark ourselves as the router of the incoming server connection
7156 if we are router ourselves. This way we can check in some packet
7157 sending functions whether it is locally connected server. For
7158 incoming router connections we put NULL.
7160 * For router sending packets locally means now always sending the
7161 packet cell wide; to local clients and local servers. For normal
7162 server sending packet locally means sending it to only local
7165 * Fixed the JOIN command to really work in router environment. If the
7166 channel is created it is always created by the router. Router is
7167 also responsible of making the initial joining to the channel,
7168 sending JOIN notify to the sending server and distributing
7169 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7170 does not exist server doesn't do anything else but forward the
7171 command to the router which performs everything.
7173 * Added silc_server_send_channel_key function to send the Channel Key
7176 * Added silc_server_create_channel_key to create new channel key. The
7177 channel key is now re-generated everytime someone joins or leaves
7178 a channel, as protocol dictates. Note: channel->key_len is the
7181 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7184 packet_receive.[ch] to separate packet sending and receiving
7185 routines. The server.[ch] now includes everything else including
7186 actual packet processing (writing and reading data) and other
7189 Renamed silc_server_private_message_send_internal to
7190 silc_server_send_private_message. The routine is still though
7191 used only to relay private messages as server does not send
7192 private messages itself.
7194 Renamed silc_server_new_channel to silc_server_create_new_channel
7195 and added new function sicl_server_new_channel that handles the
7196 incoming New Channel packet. Added also new sending function
7197 silc_server_send_new_channel to send New Channel Payload.
7199 * Added new function silc_server_notify to process incoming notify
7200 packet to the server/router. Server may then relay the notify
7201 to clients if needed.
7203 * Added new function silc_server_new_channel_user to process incoming
7204 New Channel User packet. Router will redistribute the packet and
7205 send JOIN notify to its local clients and locally connected servers
7206 if needed. Normal server will send JOIN notify to its local client
7207 on same channel when received this packet. Added also corresponding
7208 sending function silc_server_send_new_channel_user to sent the
7211 * Added boolean route argument to send_notif_to_channel and
7212 packet_send_to_channel functions to attempt to route the packet
7213 if it is TRUE and send only locally if it is FALSE.
7215 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * silc_server_replace_id now broadcasts the received replace ID
7218 packet if it is not broadcast packet already. The router must
7219 broadcast to inform other routers about changed ID.
7221 * Added backpointer to server's router into SilcServer context in
7222 silcd/server_internal.h.
7224 * Fixed silc_server_packet_broadcast to send correct broadcast
7227 * The channel key is now distributed to the local client as soon
7228 as it is received from the router (in router environment) so that
7229 no other packet may be sent for the channel until client has
7232 * silc_server_remove_channel_user now broadcasts the received
7233 Remove Channel User packet if it is not broadcast packet already.
7234 The router must broadcast to inform other routers about removed
7237 * Added users field into SilcPacketContext that is a reference count
7238 of the context. One can increase the reference count by calling
7239 silc_packet_context_dup which is now changed to just increase the
7240 reference count instead of duplicating the data. The reference
7241 count is decresed by calling silc_packet_context_free that will
7242 free the data after the reference count hits zero.
7244 For now on the packet context and everything allocated into it
7245 (including the raw packet from network) must be freed by calling
7246 the new silc_packet_context_free function. Added also new function
7247 silc_packet_context_alloc that must be used now to allocate the
7248 context. This also means that if a routine is asynchronous from
7249 silc_[client/server]_packet_parse_type the packet context must
7250 be duplicated by calling silc_packet_context_dup. Otherwise it
7251 gets free'd after silc_[client/server]_packet_parse_type returns.
7252 Also, one must remember that if packet is duplicated then its
7253 reference count must be decresed by calling the free function as
7254 many times as it was duplicated.
7256 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7257 from both client and server.
7259 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Made joining to a channel working in router environment.
7263 * Cleaned up JOIN command on server side and create function
7264 silc_server_command_join_channel internal routine to make the
7267 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Changed silc_command_pending list to SilcDList. Also, added
7270 `ident' field to SilcServerCommandPending structure to identify
7271 the reply and to call correct callback.
7273 Added silc_server_command_pending_check function to replace the
7274 corresnponding macro. The silc_command_pending list is not
7277 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7278 to set identifier to previously allocated Command Payload. It
7279 is used to set identifier for command when resending Command
7282 * Added silc_command_payload_encode_payload to encode Command
7283 Payload buffer from SilcCommandPayload structure.
7285 * Added silc_argument_payload_encode_payload to encode Argument
7286 payload buffer from SilcArgumentPayload structure.
7288 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Changed WHOIS command to support router connection on server side.
7291 The whois request is always sent to router unless the server is
7292 standalone server. After server has received the reply from the
7293 router will it send the reply to the client.
7295 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7296 broadcast received broadcast packet. The function is used only
7297 by router. The broadcast packet is always sent to the router's
7300 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7301 render given ID to printable string, for log files for example.
7303 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Made basic router to router connections working. At least they
7306 can now connect to each other but nothing really works the way
7307 they are supposed - yet.
7309 * Added new initiator token to RouterConnection configuration
7310 file in silcd/serverconfig.[ch]. It is used to tell whether we
7311 are the initiator to the remote router or whether we'll expect
7312 the other end to connect.
7314 * Moved registering of listener task to silc_server_init, hence
7315 the server starts listenning as soon as it is run, even if it
7316 does not have connections to other routers. Let's see how well
7319 * Changed default connection retry timeouts for more suitable in
7322 * Removed cipher and such arguments from silc_idlist_add_client
7323 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7324 Added new function silc_idlist_add_data to add the keys and stuff
7327 * Added SilcIDListData structure and added it to SilcClientEntry
7328 and SilcServerEntry as their first field in the structure. This
7329 way we can explicitly cast the ID entries to the SilcIDListData
7330 structure and get common data for the entries. In past, we had
7331 to first check what type of connection it is and then cast it to
7332 correct ID entry type. Now, we can directly cast the opaque
7333 pointer to the SilcIDListData (no matter what ID entry it actually
7334 is) and get the data needed.
7336 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7339 in some circumstances even if threre were timeout tasks, though not
7340 IO tasks, but tasks anyway. Now fixed.
7342 * Defined SilcServerConnection structure to hold connection specific
7343 stuff about directly connected servers and routers. The definition
7344 is currently in silcd/server_internal.h. I thought about having
7345 a bit more important role fro this struct but for now it is used
7346 only when connecting to other server (or router actually).
7348 * Added connecting retry support in server when connecting to
7349 router(s). The retry feature implement exponential backoff
7350 algorithm. Also, added SilcServerParams structure to hold default
7351 parameters for server. For now, it include these retry settings
7352 and are hard coded. After server is moded to be as Silc Server
7353 Library this structure will be more important.
7355 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7357 * Changed client librarys channel->clients table to SilcList and
7358 changed code accordingly.
7360 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7362 * Changed client's channel table to SilcList and changed code
7363 accordingly. Also changed SilcChannelClientEntry to include back-
7364 pointer to the channel so that client entry can use that structure
7365 as list as well and we have fast cross-reference to the channel.
7366 This change dramatically decreased the complexity of channel
7367 handling with client entry and vice versa (removed one extra
7368 loop when searching for channel entry from many functions).
7370 * Changed server->sim from table to SilcDList and changed code
7373 * NAMES command can now be used from user interface. It will show
7374 the user list on the channel, neatly.
7376 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7377 Code now saves realname of the user if it becomes available.
7379 * Renamed configure.in to configure.in.pre and made ./prepare
7380 script to automatically add correct version string to
7381 configure.in which it creates from configure.in.pre.
7383 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7385 * NAMES command reply now shows users mode with the nickname when
7388 * Moved silc_client_ch[u]mode[_char] functions from
7389 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7390 place sucks, they are utility functions and should be in some
7393 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7395 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7398 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Added TRQ (efficient deque and list library) into lib/trq. This is
7403 a very good list library that is currently used in the SILC. Defined
7404 SilcList API over the library because I didn't like the API very
7405 much. See lib/trq/silclist.h for the API and examples of how to
7406 use the API. Fixed various places in the code to use the new
7407 SilcList API. The SilcList is meant for lists that has a structure
7408 already defined as a list. It is not suitable to add just some
7409 context to the list (in TRQ, the context is the list actually).
7411 So, I defined SilcDList that can be used for the purpose where
7412 predefined list structure does not exit. This can be used as
7413 such list. Now some context just can be added to the SilcDList.
7414 Currently this list is not used in the SILC just yet, though there
7415 are a lot places where this can replace dynamically allocated
7416 tables and I will fix these places, later, to use SilcDList.
7417 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7418 and use TRQ internally).
7420 Also fixed some annoying warning messages that the original TRQ
7421 code generated. Also minor changes to TRQ's Makefile.in.
7423 * Added support for querying by Client ID to both WHOIS and
7424 IDENTIFY commands into server, as required by the protocol.
7426 * Removed method function pointers from SilcBuffer structure. They
7427 weren't used to anything and just increased the context size for
7428 no good reason. This change also made silc_buffer_alloc and
7429 silc_buffer_free functions inline functions.
7431 * Disabled command flooding detection support until it's fixed so
7432 that it accepts commands in but does not execute them more than once
7435 * Added silc_net_localhost(), to return local hostname, into
7436 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7437 that must be initialized before calling silc_client_init.
7439 * Added new function: silc_server_send_notify_on_channels to send
7440 notify messages to all channels client has joined. It is assured
7441 that the message is sent only once per client.
7443 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7444 lib/silcutil/silcutil.[ch] as silc_format function. The new
7445 function is generic and is used by server as well, not only by
7446 the logging routines.
7448 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7449 the provided version string was not acceptable. Added new function:
7450 silc_ske_check_version into lib/silcske/silcske.h. The function
7451 must be implemented by the application (client or server) and it
7452 does not reside in the SKE library. The function checks the version
7453 string remote end sent.
7455 * Added back pointers (to opaque context and to SilcSocketConnection)
7456 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7458 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7459 duplicate packet context structure.
7461 * Changed `notify' client operation to send same arguments as client
7462 receives from server except for ID's. ID's are mapped to correct
7463 ID entry and that is returned. Also, if channel entry is not sent
7464 by server but the notify is for channel the channel entry is sent
7465 to application (otherwise application doesn't know that it is for
7466 channel (library gets it from packet's Destination ID)).
7468 * Added silc_client_remove_from_channels into client library to
7469 remove a client from all channels it has joined to. Used when
7470 received SIGNOFF notify from server. Added also new function
7471 silc_client_replace_from_channels to replace old ID entry with
7472 new ID entry on all channels. Used when received NICK_CHANGE
7475 * Fixed ID Cache list handling in silc_idlist_get_client in
7476 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7477 to get (or query) client by ID.
7479 * Updated TODO list.
7481 * Added connection authentication status message defined by the
7482 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7483 support for these into the code in client and server side.
7485 * Added generic function silc_client_send_command to send any command
7486 with variable argument list. Application should use this function
7487 to send commands if the command functions provided by the library
7488 does not suite for the application's user interface needs.
7490 * Added new `failure' client operation. Application is notified about
7491 received failure packet if client is executing a protocol. In this
7492 case the protocol's execution has failed.
7494 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7495 is required by the protocol.
7497 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7498 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7501 * Added status flag to SilcSKE object to indicate realtime status
7502 of the SKE protocol.
7504 * Application receives now exactly same command reply arguments as
7505 the library receives from server. However, if ID is received the
7506 corresponding ID entry is returned to the application (eg. Client
7507 ID is mapped to correct SilcClientEntry entry and that is returned).
7508 Changed command_reply client operation due to this change.
7510 * Changed all ID's in commands and in command replys as ID Payloads.
7511 Change affected both client and server side codes.
7513 All ID's sent in SILC network (with execption of ID's in SILC
7514 Packet header) are sent in ID Payload to support variable length
7517 * Server now notifies nick changes and notifies all clients on
7518 the channels about the new nickname (about the new Client ID,
7521 * Implemented CMODE command to change channel modes. Supports all
7522 channel modes defined by the protocol specs except ban and invite
7523 lists. (Also, private channel key mode is supported but support for
7524 setting private channel key in client is missing, thus, this mode
7525 has no effect on client side (except that server requires that the
7526 client uses private channel key and normal channel traffic does not
7529 Also, invite mode works per se, but INVITE command does not work
7530 yet correctly, so you can set channel as invite only channel but
7531 inviting clients to the channel does not work (it is yet to be
7532 thought what's the best way to do it).
7534 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7535 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7536 Implemented CUMODE command to change user's mode on the channel.
7537 Supports all modes defined by the protocol specs.
7539 * Added NAMES command reply to return users modes on the channel.
7541 * Removed unnecessary and slow ciphers from lib/silccrypt.
7543 * Set SO_KEEPALIVE option to connection sockets by default.
7545 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7547 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7548 redefined the Notify Payload into protocol specs.
7550 * Added silc_id_payload_parse_id to get ID directly from raw
7553 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7555 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7556 accept searching by Client ID as well.
7558 * Added support for LEAVE and SIGNOFF notify types in client library.
7560 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7561 to parse ID Payload from raw data.
7563 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7565 * Added flags parameter into silc_ske_assemble_security_properties
7566 function in lib/silcske/silcske.[ch].
7568 * Changed notify client operation to fit better for notify messages
7569 sent by server. The notify payload received from server is now
7570 passed to the application (after parsing it to SilcNotifyPayload).
7571 It is application's responsibility to retrieve the arguments
7572 from the payload and show the message the way it wants. The message
7573 sent by server is implementation specific.
7575 * Changed public keys to comply with the protocol specification.
7576 Old public keys are not supported anymore and are not compatible.
7578 * Removed nickname from Channel Payload as the latest draft removed
7579 it. The client must resolve the nickname from the NAMES command
7580 reply received when it joined the channel.
7582 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7584 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7586 * Fixed some errors in protocol specification drafts.
7588 * Created lib/silccore/silcnotify.c to implement Notify Payload
7589 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7590 generic payloads described by protocol specifications. The file
7591 includes implementations for ID Payload and Argument Payload.
7593 * Changed Command Payload implementation to use the new Argument
7594 Payload. Changed command_xxxx_payload to command_payload_xxxx
7595 to comply with SILC coding conventions.
7597 * Added suppport for Argument Payload handling in Notify Payload
7598 implementation as protocol requires it. Added the new support
7599 into server and client lib as well.
7601 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7603 * Added support for multiple nicknames on same channel. [n] is
7604 added locally to the nickname if there are more than one same
7605 nicknames on the channel.
7607 * Server now sends all nicknames that matched WHOIS request.
7608 Client also shows the list received from server.
7610 * Added TOPIC command to client side. User can now set and show
7611 current topic on channel.
7613 * Added MOTD command to client and server. Also, server sends the
7614 motd when client connects to the server.
7616 * Changed version strings to comply ISO 8601.
7618 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7620 * Fixed protocol error handling in client library. It should now
7621 cope even if the SKE fails for some reason.
7623 * Made new protocol specification drafts for submitting to IETF.
7625 * Implemented TOPIC command to server in silcd/command.c.
7627 * Added two new notify types into lib/silccore/silcnotify.h:
7628 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7629 notify nickname change and topic setting/change on a channel.
7631 * API change of command_reply operation in client library. The
7632 application gets now the status type received from server as well.
7634 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7638 * Cras fixed and optimized the packet handling even further and
7639 it should work now. Minor change to the prototype of function
7640 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7642 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Added new function into lib/silcutil/silcschedule.[ch]:
7645 silc_schedule_with_fd to select() a specified fd. The function
7646 returns after timeout expires or data arrives or goes. The
7647 function is used by packet routines to wait that all data is
7648 received from network.
7650 * Fixed data reading from network in lib/silccore/silcpacket.c.
7651 The code now assures that all data is read from the fd and then
7652 continues packet processing. This was a bug fix since the code
7653 used to drop some data in some circumstances.
7655 * Added new function into lib/silcclient/client.[ch]:
7656 silc_client_start_key_exchange to start key exchange after
7657 connection has been established to server. The code internally
7658 now uses this funtion but its main purpose was to provide it
7659 for applications that perform their own connecting. After
7660 application has created a connection it merely calls this
7661 function to start the key exchange between client and server.
7662 The library takes care of everything else after that.
7664 Updated also lib/silcclient/README to explain the usage of
7667 * Do not send to application information that connection has
7668 been established. Application gets notified it by connect
7671 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Applied cras's patch to add silc_schedule_one function. The
7674 function runs scheduler once and returns.
7676 * Fixed the scheduler after cras messed it up. The timeout
7677 handling works now as it's supposed to work.
7679 * Added into lib/silccore/ silcnotify.h to include notify
7680 message types support. Changed silc_server_send_notify*
7681 functions, in server.[ch], to support those new notify types.
7682 Added the support for the notify types into client library,
7683 as well. Added new notify client operation into ops.h in
7686 * Changed silc_server_packet_send_to_channel to send normal
7687 packets instead of just channel message packets. The function
7688 is now used to send the notify packets to channels. It is not
7689 used to send channel message packets anymore, as server never
7692 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7693 va_arg()s as it seems to require it nowadays. I guess, if SILC
7694 is compiled with older va_arg() the new code should work anyway.
7696 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7698 * Splitted core library. Core library (lib/silccore) includes
7699 now only SILC protocol specific core (and common) components.
7700 Created new utility library (lib/silcutil) that includes more
7701 generic purpose stuff. The stuff for util library was taken
7702 from the old core library. This was minor and easy split.
7704 * Created SILC Client Library (lib/silcclient) that includes
7705 implementation of the SILC client without user interface. This
7706 was major move from silc/ directory. The code has been changed
7707 so that it is transparent towards the user interface. The
7708 silc/ directory includes now the same user interface as before
7709 and it uses the new client library. Read lib/silcclient/README.
7710 Basicly, the client library performs everything else related
7711 to SILC except user interface handling. Also, configuration
7712 files are considered to be part of user interface and library
7713 does not handle them.
7715 This change also changed a lot of structures, function naming etc.
7716 Most important change was that SilcClientWindow object was
7717 renamed to SilcClientConnection in the client library. Created
7718 also new file lib/silcclient/ops.h. Also added new files
7719 silc/local_command.[ch] and silc/client_ops.[ch].
7721 All these changes were made to make it easier for user interface
7722 designers to create what ever user interface for the SILC client
7725 It is also expected that the server will be moved to lib
7726 directory as well and SILC Server Library will be created;
7727 sometimes in the future.
7729 * Removed Local commands from lib/silccore/silccommand.h as
7730 they are application specific and new client library does not
7731 handle any of those anymore.
7733 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7734 old client implementation in silc/.
7736 * Added support for callback functions in SILC_LOG_* macros.
7737 Application can now set its own callbacks that will be called
7738 instead of using the default functions that will always print
7739 the debug messages to stderr (or stdout). Also, debugging can
7740 now be disabled by setting silc_debug to FALSE and re-enabled by
7741 setting it to TRUE. Note, that logging will still work even
7742 if debugging is disabled.
7744 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7745 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7746 silc_log_reset_debug_callbacks.
7748 * To enable debugging in silc client one must give now -d
7749 option on command line.
7751 * Changed silc_schedule_init to automatically allocate task queues
7752 if they are not allocated before calling it.
7754 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Added GMP 3.1 into math library.
7758 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7761 a channel in SILC network. The packet is used by servers and
7762 routers to notify other routers that user has left a channel.
7763 This little feature was missing until now. Added the feature
7764 to protocol specification as well.
7766 Added functions: silc_server_send_remove_channel_user and
7767 silc_server_remove_channel_user into server.[ch].
7769 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7770 lib/silccore/silcpacket.h. However, they are not implemented
7773 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7775 * Fixed joining to a channel and sending channel messages
7776 between server and router. The channel message sending should
7777 now work inside a cell.
7779 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7781 * Fixed the private message sending between server and router.
7782 The private message sending should now work inside a cell.
7784 * Added silc_server_replace_id into server.[ch] to replace
7785 existing ID in the SILC network.
7787 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7788 and silc_idlist_replace_server_id into idlist.[ch] in server.
7790 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Fixed the server to server connections. Server can again now
7793 connect to router. Router to router connections probably does
7796 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7798 * Added dynamic protocol registering support. Now protocols can
7799 registered and unregistered on the fly. Patch by cras.
7801 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * Added lib/contrib directory to hold routines that some platforms
7804 don't have but are needed by SILC.
7806 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7807 into lin/contrib to provide getopt() and getopt_long() for
7808 those who don't have it.
7810 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Added AWAY command to client. When away message is set and
7813 client receives a private message packet the client automatically
7814 replies to the sender with the away message.
7816 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7817 bug seemed to be the cause of recent problems when compiling
7820 * Added version detection support to SKE protocol specification
7821 and added the new changes to the SKE implementation as well.
7822 There were other minor changes in the SKE protocol as well.
7824 Many changes in lib/silcske/silcske.[ch] and in
7825 lib/silcske/payload.[ch].
7827 * Added ^U functionality, clear input line. Patch from cras.
7829 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7831 * Mainly small bugfixes on core library. Fixed some debugging
7832 logging and buffer overflow in silclog.c.
7834 * Updated config.sub and config.guess on the distribution tree.
7836 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7838 * Added command lagging support in server. Client may execute
7839 commands now only once in two seconds.
7841 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7843 * Optimized packet reception. MAC computation and checking is now
7844 also more optimized. A lot previously duplicated code is now
7845 used as generic by both client and server.
7847 * Fixed key pair generation in clientutil.c
7849 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * Added into lib/silccore/silcbufutil.[ch] new function;
7852 silc_buffer_realloc.
7854 * Moved generic packet sending/encryption functions to
7855 lib/silccore/silcpacket.[ch] from client and server. Some
7856 rewriting of the functions.
7858 * Moved all generic packet reception/decryption functions to
7859 lib/silccore/silcpacket.[ch] from client and server. The
7860 packet processing is now much cleaner in both client and server.
7861 These were major changes in both client and server.
7863 * Created many common functions in server to do packet sending.
7864 Previously code were duplicated a lot, this has been removed
7867 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7869 * Rewrote major parts of the ID cache system. Don't know
7870 whether it is better now or not but at least the API is more
7873 * Major rewrite on ID cache stuff on client because of the ID
7874 cache API changes. Added idlist.c to client.
7876 * Also major rewrite on ID cache stuff on server as well.
7877 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7878 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7879 in hand, instead they are all put into the ID cache system now.
7880 All server_idlist_* routines uses ID cache now instead of
7881 traversing its own lists (those lists does not exist anymore).
7882 SilcIDList though still exists. Also, SilcXXXEntry's are
7885 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7887 * Finally made the SKE implementation compliant to the protocol
7888 specification. All mp integers are now binary encoded as
7889 opposed being HEX encoded.
7891 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7894 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7895 functions: silc_[encode/decode]_pem. Also added function
7896 silc_encode_pem_file to PEM encode with newlines ('\n') for
7899 * SILC public keys are now encoded either PEM or binary. Same
7900 option is for private keys as well. By default private keys
7901 are binary encoded and public keys PEM encoded. Silly HEX
7902 encoding were removed.
7904 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7905 function to create fingerprints.
7907 * Fixed a bug in SHA1; does not change the original data anymore.
7909 * Partly implemented INFO command on client and server side.
7910 Fixed CLEAR command. Changes to SERVER command; show current
7911 server(s) when giving command without arguments. Added
7912 VERSION command to client.
7914 * Added check to server that unregistered connections cannot
7915 execute commands (unless it is specificly allowed).
7917 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7919 * Fixed screen refresh.
7921 * Fixed channel joining bug from client. On some circumstances
7922 client tried to join to a channel it had already joined.
7924 * Added public key verification process into client's protocol.c.
7925 The client now verifies the public key from user and saves
7926 it into ~./silc/serverkeys/ directory.
7928 Added into: clientutil.[ch]: silc_client_verify_server_key.
7930 * Changed SKE protocol's silc_ske_initiator_finish function
7931 to accept callback function that verifies the received public
7932 key. Removed old silc_ske_verify_public_key function.
7934 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7936 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7937 silc_pkcs_private_key[_data]_set.
7939 * Made the password and public authentication more cleaner in
7940 server's protocol.c.
7942 * Removed historic and obsolete protocol `channel_auth' from
7943 both client and server.
7945 * Removed wrong way of sending command status messages from
7946 server to client in server's command.c. The old way violated
7947 protocol specification.
7949 Changes to silccore/silccommand.[ch]: removed
7950 silc_command_encode_status_payload -> not needed anymore,
7951 changed silc_command_encode_payload_va to accept extra
7952 argument on variable argument list. The argument type must
7953 now be provided to the function. Also, added new function:
7954 silc_command_encode_reply_payload_va which is same as
7955 normal command_encode_payload_va except command status type
7956 is provided as extra argument.
7958 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7960 * Added ~./silc directory handling. The directory includes the
7961 public and private keys for the client.
7963 Added silc_client_check_silc_dir, silc_client_create_identifier
7964 and silc_client_load_keys.
7966 * Implemented SILC protocol compliant public key. Added public
7967 and private key saving to and loading from files.
7969 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7970 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7971 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7972 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7973 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7975 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7976 silc_pkcs_load_[public/private]_key.
7978 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7980 * Added silc_server_get_route (route.[ch]) to get connection
7981 data for the fastest route for given ID.
7983 * Implemented INVITE command on client and server. The command
7984 were re-defined in the SILC Protocol Specification and the
7985 implementation now complies with the specification.
7987 * Implemented PING command on client and server.
7989 * Implemented NAMES command on client and server. The server side
7990 supports currently only normal server not router server yet.
7991 Some changes to NAMES definition in SILC protocol specification.
7993 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7995 * Implemented LEAVE command on client and server.
7997 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7998 again. This change was made to the protocol as well. Server
7999 should not violate the protocol specification anymore.
8001 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8003 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8004 was tested. SOCKS4 was not but should work anyway.
