1 Wed Apr 17 22:07:59 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
3 * Fixed a bug in the pid writing function, which couldn't be
4 written in a root-owned directory.
6 Tue Apr 16 18:29:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Merged irssi crash fixes on /QUIT, patch from cras.
10 Sun Apr 14 20:41:28 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
12 * Fixed a bug in library where sending a bogus authentication
13 payload would lead to a crash. Affected file is
14 lib/silccore/silcauth.c.
16 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
18 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
19 must be handled by the application and should tell the application
20 that an error message was already printed, and it should print the
21 config coords (line, filename, ...). Affected files are
22 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
24 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
25 server config parsing code more readable.
27 Fixed a bug in the fetch_logging() config callback.
29 Affected files is silcd/serverconfig.c.
31 * Drop root privileges when started in foreground. Don't drop them
32 if debugging also. Affected file is silcd/silcd.c.
34 Wed Apr 3 12:36:05 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
36 * Added better error logging in rekey protocol. Affected file
39 * Do not check public key types in SKE during rekey. Affected
40 file lib/silcske/payload.c.
42 * Fixed the rekey protocol with PFS, which was totally broken.
43 Affected file silcd/protocol.c.
45 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
47 * Merged version 1.1.4 of zlib. Even if it not currently in use,
48 it's good not to have security holes here.
50 * Fixed a negative refcount situtuation for the config context.
51 Affected file is silcd/serverconfig.c.
53 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
55 * ROBOdoc documented lib/silcutil/silcutil.h.
57 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
59 * Changed the silc_get_username and silc_get_real_name to
60 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
62 * Fixed the Irssi SILC Client to use the silc_get_username and
63 silc_get_real_name insted of glib routines since the glib
64 routines only corrupt stack. Fixes the Irssi SILC to work in
65 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
67 * Fixed the Irssi to not use g_get_home_dir since it crashes
68 or returns garbage on cygwin and corrupts stack. Added function
69 get_home_dir to Irssi routines. Affected files are
70 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
72 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
74 * And yet again reverted back the config thing since Johnny
75 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
78 * Fixed memory leaks from config object. Affected files are
79 silcd/serverconfig.[ch].
81 * Added support for adding new connections to the server in rehash.
82 After rehash they take effect.
84 Added support for changing the maximum allowed connections in
85 rehash. The number can grow but going smaller is not supported.
87 Added function silc_server_num_sockets_by_remote to the
88 silcd/server_util.[ch].
90 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
92 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
94 * Added preliminary checking during config parsing for a valid
95 public/private key and removed further checks in the code.
96 Affected files are silcd/serverconfig.[ch], server.c.
98 * Moved functions silc_server_drop() and silc_server_daemonise()
99 from server.c to silcd.c since they are stricly related to
100 the application activity.
102 * Reverted a small part of the automatic ref/unref since
103 it caused a double unref in some situations. Affected
104 files are silcd/silcd.[ch], server.c, serverconfig.c.
106 * Added some .cvsignore files in the lib directory.
108 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
110 * Fixed silc_net_gethostbyaddr to correctly resolve by
111 address. Affected file lib/silcutil/silcnet.c.
113 * Fixed the notify relaying to client. The HMAC to be used
114 with relayed packets ws wrong and caused decryption failure
115 at the client end. Affected file is silcd/packet_receive.c.
117 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
119 * Created new branch silc_protocol_1_0_branch.
121 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
123 * Changed the silc_server_config_* routines to be SilcServer
124 independent. They are now officially application specific code
125 and not part of generic server implementation. Affected files
126 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
128 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Added automatic referencing of config context in the
131 silc_server_config_alloc, and automatic unreferencing in the
132 silc_server_config_destroy. Affected files are
133 silcd/serverconfig.[ch], silcd/silcd.c.
135 * Fixed the silc_log_quick handling in the logging routines.
136 It didn't log quickly when it was TRUE. Affected file is
137 lib/silcutil/silclog.c. Also the flush delay was set even
138 if it was 0 in config file. Affected file is
139 silcd/serverconfig.c.
141 * Added support for changing key pair of the server in rehash.
142 Affected file silcd/server.c.
144 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Fixed the TOPIC_SET notify to not cras. It changed the topic
147 too early, before getting the channel entry. Affected file
148 is silcd/packet_receive.c.
150 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
152 * Added functions silc_server_config_[ref/unref], these are used
153 to prevent that the config object is destroyed.
155 No longer directly affect global variables silc_log_quick and
156 silc_log_delay, they are first cached inside the config object
157 and then applied with silc_server_config_setlogfiles().
159 silc_server_config_set_defaults() is now internal to
160 serverconfig.c, there are no reasons to show this internal stuff
163 Affected files are silcd/serverconfig.[ch].
165 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
166 fprintf's to stderr, since some code may be executed again after
167 the server went into the background. Affected files are
170 * Added rehash support. Added function silc_server_rehash() that
171 will perform all the basic tasks of the rehashing procedure.
173 * Added command line option `-x, --hexdump'. This will enable the
174 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
175 The option `--hexdump' implies `--debug'.
177 * Fixed a bad bug in the logging APIs (silcutil library) where
178 the application would crash after calling silc_log_reset_all().
180 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
182 * Fixed the KICKED notify handling in client library to
183 correctly remove the channel and all entries from the
184 channel when I was kicked. This bug crashed the client.
186 Fixed yet another but in KICKED notify handling to remove
187 the kicked client correctly from the channel.
189 Affected file is lib/silcclient/client_notify.c.
191 * Fixed a minor bug in looking up correct client entry
192 in KICKED notify in server. Affected file is
193 silcd/packet_receive.c.
195 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
196 sources correctly to distribution. Fixes --with-gmp option.
198 * Removed the manual rehashing from ID Cache, and changed it
199 to use the SILC Hash Table's auto rehash feature. Affected
200 file is lib/silccore/silcidcache.c.
202 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
204 * Fixed a bug in the silc_client_nickname_format function that
205 handles the multiple same nickname formatting. Two clients
206 with same nickname caused problems after the first one left
207 and rejoined. It didn't format the nickname correctly.
208 Affected file is lib/silcclient/idlist.c.
210 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
212 * Don't change the topic if olod topic is same as new one.
213 Affected file is silcd/packet_receive.c.
215 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
217 * Added cross-reference support to the SILC Documentation
218 generator. All types across all HTML files are now cross-
219 referenced. Affected files util/robodoc/generator.c and
220 scripts/silcdoc/silcdoc.
222 * Added file lib/silcutil/silctypes.h to include all the
223 arithmetic type definitions and some macros. Removed
224 includes/bitmove.h and moved macros to silctypes.h.
226 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
230 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
232 * Added `type' argument to silc_id_payload_parse_id function which
233 now returns the type of the ID to the sent pointer. Affected
234 file is lib/silccore/silcid.[ch].
236 * Added check for CMODE_CHANGE notify type that mode change is
237 allowed by the sender. Affected file silcd/packet_receive.c.
239 * Added check for CUMODE_CHANGE notify type that mode change is
240 allowed by the sender. Affected file silcd/packet_receive.c.
241 Added the ID type as CUMODE_CHANGE notify type as argument
242 to the `notify' client operation. Affected files are
243 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
245 * Added function silc_client_add_server to the client library.
246 Added support for resolving also channel and server info when
247 received unknown entity in notify packet. Affected files are
248 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
250 * Added function silc_command_get_status to return the command
251 status from the command reply's argument payload. Affected files
252 are lib/silccore/silccommand.[ch].
254 * Added check for KICKED notify type that the kicking is
255 allowed by the client. Affected file silcd/packet_receive.c.
257 * Created function silc_get_input which can be used to get input
258 (echo on or off) from user on command line. Affected files are
259 lib/silcutil/silcutil.[ch].
261 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Optimized silc_server_packet_relay_to_channel function.
264 Added new function silc_channel_message_payload_encrypt which
265 can be called directly if channel message payload needs to
266 be encrypted and is already encoded (no need to call _encode
267 function). Packet relaying is now done by router without any
268 extra memory allocations. Affected files are
269 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
272 * Fixed the INVITE notify handling. It took wrong arguments
273 as invite list and invite delete. Affected file is
274 silcd/packet_receive.c.
276 * Added check for TOPIC_SET notify type that the topic change is
277 allowed by the client. Affected file silcd/packet_receive.c.
279 * Added check for INVITE notify type that inviting is allowed by
280 the client. Affected file silcd/packet_receive.c.
282 * Changed the silc_server_client_on_channel to return the
283 SilcChannelClientEntry as well. Moved the function
284 silc_server_check_cmode_rights to server_util.[ch].
285 Affected files are silcd/server_util.[ch], silcd/command.c.
287 * Added function silc_server_check_umode_rights to check whether
288 changing client's user mode is allowed. Added check for
289 UMODE_CHANGE notify type that the umode change is allowed
290 by the client. Affected files are silcd/server_util.[ch],
291 silcd/packet_receive.c and silcd/command.c.
293 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
295 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
296 ID length. It ignored that ID can be IPv6 based as well.
297 Affected file lib/silccore/silcpacket.h.
299 * Fixed the silc_id_id2str and silc_id_str2id to take the
300 IPv6 address offset's into consideration. Affecte file is
301 lib/silccore/silcid.c.
303 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
305 * Fixed the internal Unix scheduler functions to check for
306 NULL context they may receive. The affected file is
307 lib/silcutil/unix/silcunixschedule.c.
309 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
311 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
312 can specify different directory with --home command line
313 parameter. Affected files irssi/src/silc/core/client_ops.c,
316 * SILC-specific commands aren't now executed if the active server
317 isn't of SILC-type, so there won't be problems with having
318 IRC and SILC protocol support in same client. Affected files
319 irssi/src/silc/core/silc-channels.c, silc-servers.c,
322 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Improved the signal support in SILC Schedule. Added new
325 function silc_schedule_signal_call which is used by application
326 to mark a signal to be called. It is now safe to perform
327 any kind of tasks in signal callbacks since it is guaranteed
328 that the application specified signal callback is called
329 after the signal is over. Affected files are
330 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
332 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
334 * Added `name' field to SilcChannelPrivateKey to represent
335 application given name for the key. Moved also the context from
336 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
337 Added the `name' argument also to the function
338 silc_client_add_channel_private_key.
340 Added function silc_client_current_channel_private_key to set the
341 current channel private key in use.
343 Added "change" command to KEY command which can be used to change
344 the current channel private key. Bound the command also to
347 Also affected files lib/silcclient/client_channel.c,
348 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
350 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
352 * Added silc_rng_get_byte_fast function in to the
353 lib/silccrypt/silcrng.[ch].
355 * Changed the interface of silc_packet_assemble and the
356 silc_packet_send_prepare. If silc_packet_assmble is now
357 called the application does not call silc_packet_send_prepare
358 because the library will call it automatically. These
359 interfaces now also return a reference to the outgoing buffer
360 which includes the assembled packet, which the application can
361 use to encrypt the packet.
363 Affected files are lib/silccore/silcpacket.[ch],
364 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
365 silcd/packet_send.c, server_backup.c and packet_receive.c.
367 * Fixed a packet sending bug on very high load, where outgoing
368 packet queue wasn't handled correctly and packets got corrupted.
369 Affected files are lib/silcutil/*/silc*sockconn.c,
370 lib/silcclient/client.c and silcd/server.c.
372 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
374 * Added macro SILC_PACKET_DATALEN which can be used during
375 packet assembling to check whether the data to be added to
376 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
377 len is truncated until it fits it.
379 Added checks for maximum length of channel message payload and
380 private message payload also.
382 Added checks for maximum packet length in server and in
385 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
386 lib/silcclient/client.c, lib/silccore/silcchannel.c and
387 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
388 lib/silcclient/client_prvmsg.c.
390 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Added silc_server_packet_queue_purge call to the
393 silc_server_disconnect_remote to assure that all data in the
394 queue before disconnecting is sent to the network. Affected
397 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
399 * Added the deleting of server's own ID cache entry to the
400 silc_server_free function. Free also everything else that
401 has been allocated in silc_server_init. The affected file
404 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
406 * Added functions silc_parse_version_string, silc_version_to_num,
407 and silc_ske_parse_version to parse SILC protocol style version
408 strings. Affected files lib/silcutil/silcutil.[ch] and
409 lib/silcske/silcske.[ch].
411 * Added new configuration params: version_protocol, version_software
412 and version_software_vendor to specify what version the remote
413 host must at least be to be able to connect to server. The vendor
414 string can be regex matched too. Added new function
415 silc_server_connection_allowed to check maximum number of allowed
416 connections, and allowed versions for incoming connections.
417 Affected files are silcd/server.c, server_util.[ch] and
420 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
422 * Added preliminary support for signals in scheduler. The
423 signals we care about are now blocked always when the scheduler
424 is locked. This way we can synchronise the use of signal with
425 scheduler. It is guaranteed that when signal occurs the scheduler
426 is not locked, and thus new tasks can be safely added to the
429 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
430 to silc_schedule_internal_init and silc_schedule_internal_uninit.
431 Added new platform specific routines
432 silc_schedule_internal_signals_[un]block and
433 silc_schedule_internal_signal_[un]register.
435 Added new functions to SILC Schedule API:
436 silc_schedule_signal_[un]register. Each signal that application
437 is going to use should be registered to the scheduler.
439 Affected files are lib/silcutil/silcschedule.[ch],
440 lib/silcutil/*/silc*schedule.c.
442 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
444 * Check for unauthenticated client and server in the
445 silc_server_new_client and silc_server_new_server functions.
446 Affected file silcd/packet_receive.c.
448 * Added function silc_string_is_ascii to check whether given
449 string is 7-bit ASCII string. Affected files are
450 lib/silcutil/silcutil.[ch].
452 * Added function silc_id_is_valid_server_id into the
453 silcd/serverid.c and added checking for valid Server ID's in
454 silc_server_new_server. The Server ID must always be based
455 on the server's public IP address.
457 * Added logging of DISCONNECT packet message in the server.
458 Affected file silcd/server.c.
460 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
462 * Changed all library interfaces that use Global RNG to also
463 accept SilcRng as argument. Affected files are
464 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
465 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
466 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
467 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
470 * Added function silc_pkcs_generate_key to the
471 lib/silccrypt/silcpkcs.[ch] for applications so that they
472 don't need to do pkcs->pkcs->init calls anymore.
474 * Remove SilcSocketConnection from the SFTP API since it really
475 wasn't needed there. The application has the information
476 saved in its contexts anyway and the SFTP layer doesn't need
477 know about it. Affected files lib/silcsft/silcsftp.h and
478 lib/silcsftp/sftp_[server/client].c.
480 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
481 The SilcSimContext is not SilcSim.
483 * Fixed possible buffer overflows in silc_id_render in the
484 lib/silcutil/silcutil.c.
486 * On EPOC the global crypto module lists are not used at all
487 in the crypto library. Added support for using the constant
488 algorithm list on EPOC. Affected files are
489 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
492 * Fixed the handling of third parameter of KICKED notify, since
493 it was mistakenly updated to SILC Protocol 1.0 even though it
494 is to be included in 1.1. Since it is not in 1.0 it is not
495 mandatory, and this fix now handles it only if it is provided,
496 and it is not error if it is not provided. Affected file
497 lib/silcclient/client_notify.c.
499 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
501 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
502 client. Affected file irssi/src/silc/core/client_ops.c.
504 * Merged with Irssi 0.8.4 from irssi.org CVS.
506 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
508 * Check for valid socket connection in client entries before
509 sending any messages. Fixes a crash, but doesn't fix some
510 other underlaying bug that is lurking there. Affected
511 file silcd/packet_send.c.
513 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
515 * $usermode, $cumode and $cumode_space expandos shouldn't do
516 anything with non-SILC server records. Affected file
517 irssi/src/silc/core/silc-expandos.c
519 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Fixed the silc_net_check_[host/local]_by_sock to support
522 IPv6 bound sockets as well. Now they can return IPv6 addresses
523 as well. Affected file lib/silcutil/silcnet.c.
525 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
526 Affected lib/silcutil/unix/silcunixnet.c.
528 * Fixed ID rendering (at least on some platforms, not NetBSD)
529 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
531 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
533 * Added silc_hash_public_key and silc_hash_public_key_compare
534 functions to be used with SilcHashTable. They can be used to
535 hash public keys and compare public keys in hash table. Affected
536 file lib/silcutil/silcutil.[ch].
538 * Added support for specifying multiple public keys for Client
539 connection section in server configuration file. This makes it
540 possible to accept multiple public keys from same host, or to
541 make a section that accepts any incoming host, and have the
542 accepted public keys listed in the section.
544 Added functions silc_sever_[find/get]_public_key, added the
545 support for this actually to all connection sections but only
546 the Client section is currently allowed to specify multiple

701 in normal server of global channels as well. Affected files
702 silcd/server.c, idlist.h, packet_receive.c and command.c.
704 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

716 Affected file lib/silcclient/client.c.
718 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
720 * ROBOdoc documented the lib/silcske/silcske.h, and improved
721 the SKE interface a bit.
723 * Fixed padding problem in PKCS#1. The padding was not actually
724 random since the random number generator was used incorrectly.
725 This security bug affects only when encrypting with PKCS#1, and
726 it is not currently used at all in SILC. SILC only use signing
727 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
729 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

803 whether given configuration value has been given already.
805 Affected files silcd/serverconfig.[c], server.[c].
807 * Splitted the doc/example_silcd.conf.in. Separated the crypto
808 algorithm parts and created new file silcalgs.conf, that
809 is now included from the example_silcd.conf.in.
811 * Optimized the silc_server_connect_to_router_second to take
812 the connection configuration object from the SilcServerConnection
813 object instead of finding it during the connecting phase.
814 Added the configuration object to SilcServerConnection struct.
815 Affected files silcd/server_internal.h, server.c.

843 public key is set. If not set, public key is preferred.
844 This has effect only when being initiator (responder will try
847 Added support for authentication with passphrase and public key
848 at the same time. The passphrase is tried first always since
849 it is faster to check.
851 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
853 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

899 * Fixed the file transfer's key agreement payload to include
900 zero port also if the hostname is NULL because it could not
903 Call file transfer monitor callback now also if error occurs
904 during key agreement protocol.
906 Changed the silc_client_file_send interface to return the
907 SilcClientFileError instead of session id. The session ID
908 is returned into pointer provided as argument.

925 file lib/silcutil/silclog.c.
927 * Fixed the channel message payload decryption in the function
928 silc_channel_message_payload_decrypt to not modify the original
929 buffer before it is verified that the message decrypted
930 correctly. Otherwise, next time it is called with correct
931 channel key it won't encrypt since the payload is corrupted.
932 Affected file lib/silccore/silcchannel.c.
934 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

947 the table with foreach callback. The current entry may
948 become invalid in the callback but it was referenced after
949 the callback returned.
951 Do not allow auto rehashing of hash table during the
952 silc_hash_table_foreach operation, for same reasons as it is
953 not allowed for SilcHashTableList. Affected files are
954 lib/silcutil/silchashtable.[ch].
956 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

977 users list to SilcHashTable. The affected files are
978 lib/silcclient/idlist.[ch].
980 * Fixed a bug in hash table tarversing. While the hash table
981 is traversed with SilcHashTableList the table must not be
982 rehashed. It is now guaranteed that auto rehashable tables
983 are not rehashed while tarversing the list. Also defined that
984 silc_hash_table_rehash must not be called while tarversing
985 the table. Added function silc_hash_table_list_reset that must
986 be called after the tarversing is over. The affected files are
987 lib/silcutil/silchashtable.[ch].
989 * Changed all hash table traversing to call the new
990 silc_hash_table_list_reset in server and in client library.
992 * Added function silc_client_on_channel to return the
993 SilcChannelUser entry if the specified client entry is joined
994 on the specified channel. This is exported to application as
995 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1004 lists correctly. Affected file silcd/command.c.
1006 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1008 * When sending JOIN command to router for processing the
1009 sender's old command identifier was not saved back to the
1010 sender's command context, fixed now. The affected file is
1013 * Create the key in JOIN command of the router did not return
1014 the channel key, added check for this. Affected file is
1017 * Fixed a channel ID update bug in JOIN command reply. Do
1018 not directly upgrade the ID but call the function
1019 silc_idlist_replace_channel_id if the ID was changed.
1020 Affected file silcd/command_reply.c.
1022 * Fixed memory leaks from command calling if it would fail.
1023 Affected file silcd/command.c.

1050 functions. Affected file silcd/server.c.
1052 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1053 which ID was changed. This way the router will send the
1054 user list for the channel again, and server won't be in
1055 desync in some rare circumstances. Affected file is
1056 silcd/packet_receive.c.
1058 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1084 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1086 * Added server & router operator statistics updating. Affected
1087 file silcd/packet_receive.c and silcd/command.c.
1089 * Fixed the SERVER_SIGNOFF notify handling on normal server
1090 not to save the history information for clients. Same was
1091 fixed earlier in remove_clients_by_server function, but not
1092 here. Affected file silcd/packet_receive.c.
1094 * Raised the default connection-retry count from 4 to 7 in
1095 server. Affected file silcd/server.h.
1097 * Cancel any possible reconnect timeouts when we start the
1098 key exchange. Affected file silcd/server.c.
1100 * Do not reconnect on connection failure when SCONNECT was
1101 given. Affected files silcd/server.[ch].
1103 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1105 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1107 * Fixed the NICK command to always give the unformatted
1108 nickname to the one giving the NICK command. If unformatted
1109 nickname is cached already it will be formatted and the
1110 local entry will always get the unformatted nickname.
1111 Affected file lib/silcclient/idlist.c.
1113 * Fixed some double frees from client library commands.
1114 Affected file is lib/silcclient/command.c.
1116 * Fixed CUMODE command in server to assure that no one can
1117 change founder's mode than the founder itself, there was a
1118 little bug. Affected file silcd/command.c.
1120 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Removed the SilcClientCommandDestructor from the client
1123 libary, it is not needed anymore. Affected files are
1124 lib/silcclient/silcapi.h, command[_reply].[ch],
1125 client_notify, idlist.c.
1127 * Fixed GETKEY command to first resolve client, and then
1128 resolve the server only if the client was not found, instead
1129 of resolving both at the same time. Affected file is
1130 lib/silcclient/command.c.
1132 * Added silc_client_start_key_exchange_cb and lookup the
1133 remote hostname and IP address before starting the key
1134 exchange with server. The affected file is
1135 lib/silcclient/client.c.
1137 * The server's public key is now saved using the IP address
1138 of the server and not the servername for the filename.
1139 The hostname public key filename is checked as an fall back
1140 method if the IP address based filename is not found.
1142 Fixed the GETKEY command to save the fetched server key
1143 in correct filename.
1145 Print the remote server's hostname now when new key is
1146 received during connection process. Affected file is
1147 irssi/src/silc/core/client_ops.c.
1149 * Return always our own public key to the client if it asks
1150 for it with GETKEY command. Affected file silcd/command.c.
1152 * Removed the use_auto_addr variable from default config
1153 file since it was in wrong section. Affected file is
1156 * Fixed TOPIC_CHANGE notification to not route it when it
1157 was sent using silc_server_send_notify_to_channel function.
1158 Affected file silcd/command.c.
1160 * Fixed silc_server_send_notify_kicked to send the kicker's
1161 Client ID also, it was missing. Affected files are
1162 silcd/command.c, silcd/packet_send.[ch].
1164 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1166 * Do not save client history information in SERVER_SIGNOFF.
1167 Fixes the bug in normal server that it does not detect
1168 the client becoming valid after the server becomes back
1169 online. Affected file silcd/server_util.c.
1171 * Added `sock_error' field into the SilcSocketConnection
1172 context. When error occurs during socket operation (read
1173 or write) the error is saved. Added also new function
1174 silc_socket_get_error to return human readable socket error
1175 message. Affected files are lib/silcutil/silcsockconn.[ch],
1176 lib/silcutil/unix/silcunixsockconn.c, and
1177 lib/silcutil/win32/silcwin32sockconn.c.
1179 * The server now prints the socket error message in the
1180 signoff for client. Affected file silcd/server.c.
1182 * Fixed the `created' channel information sending from router
1183 to server in JOIN command. Checks now whether the channel
1184 really was created or not and set it according that.
1186 Fixed the JOIN command to use the client entry's current
1187 ID during the joining procedure instead of the one it sent
1188 in the command (it is checked though), since it can change
1189 between the packet processing and command processing, and
1190 would just case unnecessary pain in the client end. Affected
1191 file silcd/command.c.
1193 * Fixed a channel key payload sending to use correct channel
1194 ID when the server was forced to change the channel's ID by
1195 router. Router sent the key payload with the old Channel ID.
1196 Affected file silcd/packet_receive.c.
1198 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Call silc_server_save_channel_key only if the key payload
1201 was provided in the JOIN command's command reply. Affected
1202 file silcd/command_reply.c.
1204 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1206 * Fixed silc_mp_sizeinbase to return the value correctly with
1207 MPI. Affected file lib/silcmath/mp_mpi.c.
1209 * Fixed the stop_server signal to correctly stop the scheduler
1210 and gracefully stop the server when SIGTERM or SIGINT signals
1211 are received. Affected file silcd/silcd.c.
1213 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1215 * Simple handling of TERM and HUP signals. Also added some log
1216 flushing call around. Affected file is
1219 * Fixed small bugs in silclog.c. Now buffering output will take
1220 effect after 10 seconds since startup: This will ensure that
1221 no important startup messages are lost. Also output redirection
1222 will preserve original format ([Date] [Type] message).
1223 Affected file is lib/silcutil/silclog.c.
1225 * Added two options to the config file, in the logging section:
1226 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1227 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1229 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1231 * Do not print the warning about log files not being initialized
1232 more than once to avoid excess logging. Affected file is
1233 lib/silcutil/silclog.c.
1235 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1236 the SIM copying in make install in Makefile.am.pre.
1238 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1240 * Rewritten silclog APIs. Globally interesting changes follows:
1241 silc_log_set_files() changed to silc_log_set_file().
1242 silc_log_set_callbacks() changed to silc_log_set_callback().
1243 ROBOdoc documented silclog header file.
1244 SilcLogCb now returns bool to wether inihibit the default
1245 handler or not (to keep the old behaviour return always TRUE).
1246 The new APIs should also fix the problem of the
1247 silcd_error.log file that was written in the current directory.
1250 Log files streams will remain opened after silc_log_set_file()
1251 call, means less CPU usage notably on high traffic servers.
1252 File streams are now full buffered, and flushed to the disk
1253 every 5 minutes, lesses HD activity and CPU usage.
1254 Messages can be redirected, allowing admins to configure
1255 one single logfile for all server messages.
1256 the silc_log_quick global variable to activate fast-logging.
1257 Affected files lib/silcutil/silclog.[ch]
1259 * Changed some code to conform new silclog APIs. Affected
1260 files are doc/example_silcd.conf.in, silcd/server.c
1261 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1264 * Fixed a memory leak that could occur in some situations.
1265 Affected file silcd/serverconfig.c.
1267 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1269 * Added the silc_client_del_client to remove the client from
1270 all channels as well. Affected file lib/silcclient/idlist.c.
1272 * Fixed the client library to correctly remove the client
1273 from all channels when the client entry is being destroyed.
1274 Affected file lib/silcclient/client_notify.c, command.c.
1276 * Added auto-nicking support to the client library. If the
1277 applicatio now sets client->nickname it will be sent to the
1278 server after connecting by the library. This way for example
1279 SILCNICK (or IRCNICK) environment variables will have effect
1280 and always change the nickname automatically to whatever
1281 it is wanted. Affected file lib/silcclient/client.[ch].
1283 * Renamed silc_server_command_bad_chars to the
1284 silc_server_name_bad_chars and moved it to the
1285 silcd/server_util.[ch]. Added also new function
1286 silc_server_name_modify_bad to return nickname that
1287 includes bad characters as new nickname without those
1288 bad characters. This check and modify is now used in
1289 silc_server_new_client when the username is initially set
1290 as nickname, so it must be checked to be valid nickname.
1291 Affected file silcd/packet_receive.c.
1293 * The nickname length is now taken from the packet for real
1294 and not trusted to strlen() since it clearly can return
1295 wrong length for nickname including bad characters. This
1296 also applies to channel names. Affected file silcd/command.c.
1298 * Removed the lib/silcsilm/modules directory. Modules are now
1299 compiled into the lib/silcsim. Fixed the copying of the
1300 modules to follow symbolic links in Makefile.am.pre.
1302 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1304 * Fixed silc_string_regexify list creation. Fixes bugs with
1305 BAN and INVITE commands in server. The affected file is
1306 lib/silcutil/unix/silcunixutil.c.
1308 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Removed the command destructor entirely from the server's
1311 command and command reply routines. It is not needed, and
1312 its usage was buggy and caused crashes. Affected files are
1313 silcd/command[_reply].[ch].
1315 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * Cancel protocol and NULL sock->protocol if timeout
1318 occurred during protocol. Affected file silcd/server.c.
1320 * Cancel protocol timeouts always before calling the final
1321 callback, to assure that after final callback is called
1322 no other state will be called for the protocol anymore.
1323 Affected file silcd/protocol.c.
1325 * Print error log if incoming connection configuration could
1326 not be found. Affected file silcd/server.c.
1328 * Fixed JOIN command to correctly save the founder mode
1329 to the client on normal SILC server, when the channel
1330 was created by the router. Affected file silcd/command.c.
1332 * Fixed LIST command (hopefully) to send correct reply
1333 packets. Affected file silcd/command.c.
1335 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * The silc_packet_receive_process now returns FALSE if the
1338 read data was invalid packet, and TRUE if it was ok.
1340 The server now checks that if unauthenticated connection
1341 sends data and its processing fails the server will close
1342 the connection since it could be a malicious flooder.
1344 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1346 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Make sure the warning about error opening a log file is
1349 printed only once and not everytime it fails (produces
1350 too much useless log). Affected file lib/silcutil/silclog.c.
1352 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1354 * Made the silc_server_daemonise() function more readable.
1355 Affected file silcd/server.c.
1357 * Pid file is now optional, the user may comment it out from
1358 the config file. Removed define SILC_SERVER_PID_FILE, we
1359 don't need a default any longer. Affected file
1360 configure.in.pre, lib/Makefile.am.pre.
1362 * Make some use of the pid file. The server now dies at startup
1363 if it detects a valid pid file on his path. The server would
1364 die anyway in this circumstance, because of the bind() failure.
1365 Affected file silcd/silcd.c.
1367 * No longer compiling lib/dotconf.
1369 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Fixed JOIN command parsing not to crash. Affected file
1372 lib/silcclient/command.c.
1374 * Fied the NICK_CHANGE notify to add the new client entry
1375 even it is resolved. This removes an <[unknown]> nick
1376 thingy bug in the client. Affected file is
1377 lib/silcclient/client_notify.c.
1379 * Do not try to allocate 0 bytes (efence does not like it)
1380 in lib/silccore/silccomand.c when encoding payload.
1382 * Do not take IRCNICK as nickname in Irssi SILC client since
1383 it is not possible to set nickname before hand connecting
1384 the server (TODO has an entry about adding auto-nicking
1387 * Changed the silc_server_command_pending to check whether
1388 there already exists an pending entry with the specified
1389 command, command identifier and pending callback. This is
1390 to fix IDENTIFY and WHOIS related crashes that may register
1391 multiple pending commands with same identifier. Affected
1392 file silcd/command.c.
1394 * Fixed the server to reconnect to the router even if it
1395 was already reconnecting and EOF was received. This to
1396 fix a possibility that the server wouldn't ever try to
1397 auto-reconnect to the router. Affected file silcd/server.c.
1399 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * Fixed the server's password authentication to use the
1402 length of the locally saved password, and not the one
1403 sent in the packet. Affected file silcd/protocol.c.
1405 * Fixed same password authentication problem in the
1406 Authentication Payload handling routines in
1407 lib/silccore/silcauth.c.
1409 * Yet another password authentication problem fixed with
1410 channel password handling in silcd/command.c.
1412 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * If first character of string in silc_parse_userfqdn is '@'
1415 then do not parse it. Affected file is
1416 lib/silcutil/silcutil.c.
1418 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Fixed minor bug in IDENTIFY command reply sending, which
1421 caused various weird problems during JOIN when it was
1422 resolving names for users. Affected file silcd/command.c.
1424 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Fixed the IDENTIFY command reply sending to chech better valid
1427 clients. It was possible to send incomplete list of replies.
1428 Affected file silcd/command.c.
1430 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Added silc_client_command[s]_[un]register functions now to
1433 dynamically register the commands in client library. Removed
1434 the static table of commands. This allows the client library
1435 to call commands without causing the application to know about
1436 what commands library has called.
1438 Removed the INFO command reply kludge to detect when the command
1439 was called by library. Now library use its own command reply
1440 function for INFO command.
1442 Added function silc_client_command_call to call a command.
1443 Application can use it to call command, not access the structure
1446 Now all commands that are sent by the client library (not
1447 explicitly sent by application) use own command reply functions.
1449 Affected files around lib/silcclient/ and in
1450 irssi/src/silc/core/.
1452 * Fixed the WHOIS command reply sending to chech better valid
1453 clients. It was possible to send incomplete list of replies.
1455 Fixed the WHOIS and IDENTIFY to send the request to router
1456 if normal server did not do it and did not find any results.
1458 Affected file silcd/command.c.
1460 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Moved the internal data from SilcClient context into its
1463 own file, not accesible to application. Affected files
1464 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1465 and other files in client library.
1467 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Added doc/examples installation target in Makefile.am.pre.
1472 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1475 commands the found client entry will be removed from the
1476 cache, after notifying application about the error. Affected
1477 file lib/silcclient/command_reply.c.
1479 * Changed the /MSG to check for exact nickname user gave, and
1480 not let `nick' match `nick@host' if it is only one found. Now,
1481 user must type the exact nickname (like nick@host2) even if
1482 there are no more than one same nicks found. This is to avoid
1483 a possibility of sending nickname to wrong nickname since
1484 `nick' could match `nick@host'. Affected file is
1485 irssi/src/core/silc-servers.c.
1487 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Do not print "you are now server operator" or similar when
1490 giving /away command. Affected files are
1491 irssi/src/silc/core/client_ops.c, silc-servers.h.
1493 * Made the silc_server_command_pending_error_check to send
1494 the same command reply payload it received back to the
1495 original sender of the command. This way all arguments
1496 that was received by the server will be received by the
1497 client too. Affected file silcd/command.c.
1499 * Added the silc_idcache_add to return the created cache entry
1500 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1502 * Add global clients to expire if they are not on any channel.
1503 This is because normal server will never know if they signoff
1504 if they are not on any channel. The cache expiry will take
1505 case of these entries. This is done by normal servers only.
1506 The affected files are silcd/command_reply.c,
1507 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1509 * If server receives invalid ID notification for WHOIS or
1510 IDENTIFY and the ID exists in the lists, it is removed.
1511 Affected file silcd/command_reply.c.
1513 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1514 in client then client entry that it matches is searched and
1515 the nickname is printed on the screen for user. Affected
1516 file irssi/src/silc/core/client_ops.c.
1518 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Use cache entry expire time in the LIST command reply to
1521 purge old entries from the cache after the LIST command
1522 reply has been received. This way we don't have non-existent
1523 entries in the cache for too long. Affected file is
1524 silcd/command_reply.c.
1526 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * If we are normal server, and we've not resolved client info
1529 in WHOIS or IDENTIFY from router, and it is global client,
1530 we'll check whether it is on some channel. If it is not
1531 then we cannot be sure about its validity and will resolve it
1532 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1533 file silcd/command.c.
1535 * Search channel by name (if possible) rather than by ID
1536 in IDENTIFY command's command reply. Affected file is
1537 silcd/command_reply.c.
1539 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1542 Updated specs and implemented it. Affected file silcd/command.c,
1543 silcd/packet_send.c and silcd/packet_receive.c.
1545 * Implemented the <founder auth> payload handling in the JOIN
1546 command. If provided all conditions for channel joining
1547 except requirement to provide correct passphrase can be
1548 overrided by the channel founder. Updated the protocol specs.
1549 Affected file silcd/command.c.
1551 Added support for founder auth in JOIN command in client
1552 library. Fixed the parsing of the JOIN command now to support
1553 all options as they should be. The affected file is
1554 lib/silcclient/command.c.
1556 * Optimized the WHOIS and IDENTIFY commands to send the request
1557 to router only if it includes nicknames or other names. If
1558 they include only IDs then check the local cache first before
1559 routing. Affected file is silcd/command.c.
1561 * Added channels topic announcements. Affected file is
1562 silcd/packet_receive.c and silcd/server.c.
1564 * Fixed the silc_server_send_notify_topic_set to really destine
1565 the packet to channel. Affected file silcd/packet_send.c.
1567 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1568 library. Affected file lib/silcclient/client_notify.c.
1570 * Added UMODE announcements. Affected file silcd/server.c.
1572 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Memory leak fixes in:
1576 lib/silcutil/silcsockconn.c
1577 lib/silcske/silcske.c
1578 lib/silcske/groups.c
1580 lib/silccrypt/silcpkcs.c
1581 lib/silccore/silccommand.c
1582 lib/silccore/silcidcache.c
1587 * ROBOdoc documented the lib/silcske/groups.h file and a
1588 bit changed the interface for better.
1590 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1592 * Update the client entry context in the ID cache after
1593 nick change. Affected file lib/silcclient/command.c.
1594 Fixes the CUMODE command when regaining founder privileges,
1595 and a little WHOIS problem.
1597 * Fixed silc_net_gethostbyname to correctly call the
1598 inet_ntop. Affected file lib/silcutil/silcnet.c.
1600 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1602 * Added IPv6 support checking to the configure.in.pre, added
1603 also --enable-ipv6 option to override the check. Affected
1604 file configure.in.pre.
1606 * The silc_thread_create now calls the start function
1607 directly if threads support is not compiled in. Removes
1608 ugly #ifdef's from generic code. Affected files are
1609 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.

1623 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1624 routines. Added silc_net_is_ip[4/6]. Affected file is
1625 lib/silcutil/unix/silcunixnet.c. All routines that take
1626 address as argument now supports both IPv4 and IPv6 addresses.
1628 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1630 * Fixed LIST command reply sending in server. Affected file
1633 * Server now sends the kicker's client ID in the KICK notify
1634 to the kicked client. Affected file silcd/command.c.
1636 * The client library now parses the kickers client ID and
1637 UI displays it. Affected files lib/silcclient/client_notify.c
1638 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1640 * Made all payload parsing function prototypes consistent.
1641 They all take now const unsigned char * and uint32 pair as
1642 the payload data instead of SilcBuffer. Changes all around
1643 the source tree. Other unsigned char* -> const unsigned char*
1644 changes around the tree as well.
1646 * Optimized SFTP client and server packet sending not to
1647 allocate new buffer for each packet but to recycle the
1648 first allocated buffer. Affected files are
1649 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1651 * Optimized the SFTP client to use SilcList instead of
1652 SilcDList for requests, because it is faster. Affected file
1653 is lib/silcsftp/sftp_client.c.
1655 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1656 into lib/silccore/silcid.[ch].
1658 Renamed silcpayload.[ch] into silcargument.[ch].
1660 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * If client entry is deleted with active key agreement
1663 session, abort the session.
1665 The silc_client_abort_key_agreement now calls the completion
1666 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1668 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1671 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Don't use __restrict in older GCC's. Affected file is
1674 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1676 * silc_net_localhost now attempts to reverse lookup the
1677 IP/hostname. Affected file lib/silcutil/silcnet.c.
1679 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1680 command. It can be used to gain founder privileges at
1681 the same time when joining the channel.
1683 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1684 kicker's client ID as well. Updated protocol specs.
1686 Defined that the server must send SILC_COMMAND_IDENTIFY
1687 command reply with error status to client who sent
1688 private message with invalid client ID.
1690 Updated the protocol specification.
1692 * Added silc_server_send_command_reply to send any
1693 command reply. Affected file silcd/packet_send.[ch].
1695 * Added silc_id_payload_encode_data to encode ID payload
1696 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1698 * The server now send IDENTIFY command reply with error
1699 status if client ID in private message is invalid. Affected
1700 file silcd/packet_receive.c.
1702 * Save the server key file with server's IP address in
1703 the filename instead of hostname. The affected file is
1704 irssi/src/silc/core/client_ops.c.
1706 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1711 * Added libtool support for compiling shared objects in
1712 lib/silcsim. Affected file configure.in.pre and
1713 lib/silcsim/Makefile.am. Original patch by cras.
1715 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1717 * Pid file configuration, and server's config file fixes
1718 patch by toma. Updated CREDITS file.
1720 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Fixed silc_client_channel_message to not try to decrypt
1723 the message twice if it resolved the destination client
1724 information. This could cause of dropping one channel
1725 message. Affected file lib/silcclient/client_channel.c.
1727 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1730 lib/silcclient/client.c. This function is used when the SILC
1731 Client is run under some other scheduler, or event loop or
1732 main loop. On GUI applications, for example this may be
1733 desired to used to run the client under the GUI application's
1734 main loop. Typically the GUI application would register an
1735 idle task that calls this function multiple times in a second
1736 to quickly process the SILC specific data.
1738 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1740 * Fixed silc_server_drop() for dropping the supplementary
1741 groups as well, this could cause a security hole on some
1744 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1749 * Write PID file after dropping privileges. Added -F option
1750 to run server on foreground. A patch by debolaz.
1751 Affected files silcd/server.c, silcd/silcd.c.
1753 * Fixed MOTD to return the MOTD file server name. Affected
1754 file silcd/command.c.
1756 * Added INFO command reply handling to the Irssi SILC Client.
1757 Affected file irssi/src/silc/core/client_ops.c.
1759 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * Fixed the silc_idcache_list_* routines to really support
1762 the dynamic list. Fixes a crash. Affected file is
1763 lib/silccore/silcidcache.c.
1765 * Fixed the LIST command reply to really call LIST command's
1766 pending callbacks. Affected file silcd/command_reply.c.
1768 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Update conn->local_entry->nickname after giving NICK
1771 command. Affected file lib/silcclient/command.c.
1773 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1775 * Added the [pid] option to the silcd configuration file
1777 Affected files: serverconfig.[ch] and silcd.c
1779 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1781 * Save fingerprint in WHOIS command reply in server.
1782 Affected file silcd/command_reply.c.
1784 * Fixed NICK commands pending callback registration.
1785 Affected file lib/silcclient/command.c.
1787 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1789 * Use ++server->cmd_ident when sending commands in server,
1790 instead of random number. Affected file silcd/command.c.
1792 * Fixed GETKEY command reply to call actually GETKEY pending
1793 command callbacks. Affected file silcd/command_reply.c.
1795 * A bit stricter check for nicknames. Check for same nickname
1796 in NICK command also. Affected file silcd/command.c.
1798 * Do not call INFO command everytime client ID changes, only
1799 during first connecting. Affected file lib/silcclient/client.c.
1801 * Set the new nickname only after successful command reply for
1802 NICK command is returned by server. Affected file
1803 lib/silcclient/command.c.
1805 * Remove nicknames from nicklist during server_signoff notify.
1806 Should fix /NAMES bit more. The affected file is
1807 irssi/src/silc/core/silc-channels.c.
1809 * Added `fingerprint' field to the SilcIDListData in the
1810 silcd/idlist.h to hold the fingerprint of the client's
1813 Send the fingerprint of the client's public key in WHOIS
1816 Affected files silcd/command.c, and silcd/idlist.[ch].
1818 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1819 create fingerprint from given data.
1821 * Show the fingerprint of the client's public key in WHOIS.
1822 Affected files irssi/src/module-formats.[ch] and
1823 irssi/src/silc/core/client_ops.c.
1825 * Format the multiple same nicknames also during JOIN and
1826 NICK_CHANGE notifys. Affected file is
1827 lib/silcclient/client_notify.c.
1829 * Do not print error on screen for invalid private message
1830 payload since it can come if someone is sending private
1831 messages with wrong key. Affected file
1832 lib/silccore/silcprivate.c.
1834 * Fixed multiple concurrent /PING crash. Affected file
1835 lib/silcclient/command.c.
1837 * Changed the wrong ID encoding. All IP addresses must be
1838 in MSB first order in encoded format. They were encoded
1839 wrong and was in LSB format. Affected files are
1840 silcd/serverid.c, lib/silcutil/silcutil.c.
1842 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1844 * Call the `connect' client operation through the scheduler
1845 in case of error. Affected file lib/silcclient/client.c.
1847 * Call the `failure' client operation even if the error
1848 occurred locally during a protocol. Affected file is
1849 lib/silcclient/protocol.c.
1851 * Added support of sending LIST command to router from normal
1852 server. This way normal server can get list of all channels
1853 in the network too. Fixed the channel list sending in the
1854 server too. Affected files are silcd/command.c, and
1855 silcd/command_reply.[ch].
1857 * Added silc_server_update_channels_by_server and
1858 silc_server_remove_channels_by_server. They are used during
1859 disconnection of primary router and in backup router protocol.
1860 Affected file silcd/server_util.[ch], silcd/server.c and
1861 silcd/server_backup.c.
1863 * Fixed channel adding to global list in IDENTIFY command
1864 reply in server. Affected file silcd/command_reply.c.
1866 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * If the incoming packet type is REKEY or REKEY_DONE process
1869 that packet always synchronously. Fixes yet another MAC
1870 failed error on slow (dialup) connections. Affected file
1871 lib/silcclient/client.c and silcd/server.c.
1873 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Call check_version SKE callback for initiator too. Affected
1876 file lib/silcske/silcske.c.
1878 * Implemented fix for security hole found in the SKE that was
1879 fixed in the specification few days back; the initiator's
1880 public key is now added to the HASH value computation.
1881 Added backwards support for the old way of doing it too, for
1882 old clients and old servers. Affected file is
1883 lib/silcske/silcske.c.
1885 * Enabled mutual authentication by default in SKE. If initiator
1886 is not providing mutual authentication the responder will
1887 force it. This will provide the proof of posession of the
1888 private key for responder. The affected files are
1889 lib/silcclient/protocol.c and silcd/protocol.c.
1891 * Do not cache anymore the server's public key during SKE.
1892 We do mutual authentication so the proof of posession of
1893 private key is done, and if the server is authenticated in
1894 conn auth protocol with public key we must have the public
1895 key already. Affected file silcd/protocol.c.
1897 * Added new global debug variable: silc_debug_hexdump. If
1898 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1899 file lib/silcutil/silclog.[ch].
1901 * Fixed compilation warning due to char * -> const char *.
1902 Affected files lib/silcutil/silcnet.h, and
1903 lib/silccore/silcauth.[ch].
1905 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Fixed CMODE command when new channel key was created. If
1908 the creation failed the old key was removed. Next time giving
1909 same command would crash the server since the old key was
1910 freed already. Affected file silcd/command.c.
1912 * Fixed the silc_server_announce_get_channels to not crash
1913 on reconnect. Affected file silcd/server.c.
1915 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Added silc_log_set_debug_string function to set a regex
1918 string to match for debug output. Only the function names,
1919 or filenames matching the given debug string is actually
1920 printed. This way it is possible to filter out those debug
1921 strings that user is not interested in.
1923 Fixed a bug in silc_string_regexify.
1925 Affected files lib/silcutil/silclog.[ch], and
1926 lib/silcutil/unix/silcunixutil.c.
1928 * Changed the -d options in both server and Irssi SILC client
1929 to take the debug string as argument. Affected files
1930 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1932 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Added silc_hash_babbleprint to create a Bubble Babble
1935 Encoded fingerprint. The encoding is developed by Antti
1936 Huima (draft-huima-babble-01.txt), and it creates human
1937 readable strings out of binary data. Affected file
1938 lib/silccrypt/silchash.[ch].
1940 * Print the babble print now in addition of fingerprint as well
1941 in Irssi SILC client. Affected files are
1942 irssi/src/fe-common/silc/module-formats.[ch],
1943 irssi/src/fe-common/silc/core/client_ops.c.
1945 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Fixed a security problem found in SKE. The initiator's
1948 public key too is now added to the HASH hash value creation
1949 which is signed by the responder to create the SIGN value.
1950 This will prevent anyone in the middle to lie to the responder
1951 about the initiator's public key. If this is done now, the
1952 man in the middle will get caught. Updated the protocol
1955 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Better installation directory handling. Configure module
1958 paths and other paths automatically to example_silc* files
1959 in doc/. A patch by toma.
1961 * Fixed compiler warning from MPI library, and from SILC RNG.
1964 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1965 It can be configured with ./configure. A patch by toma.
1967 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Find correct make to use in prepare-clean. A patch by
1970 toma. Affected file prepare-clean.
1972 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1974 * Added irssi variables use_auto_addr, auto_bind_ip,
1975 auto_bind_port and auto_public_ip.
1977 * Changed the interface for silc_client_send_key_agreement
1978 in lib/silcclient/silcapi.h
1982 irssi/src/silc/core/silc-core.c
1984 lib/silcclient/silcapi.h
1985 irssi/src/silc/core/silc-channels.c
1986 lib/silcclient/client_keyagr.c
1989 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Added silc_pkcs_public_key_compare to compare two
1992 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1994 * Check that the client who set the founder mode on the
1995 channel is the same client that is giving the founder
1996 mode to itself. It is done by comparing the saved public
1997 key (it is saved even in the authentication is passphrase).
1998 Affected file silcd/command.c.
2000 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Do not process packet for disconnected socket connection.
2003 Affected file lib/silccore/silcpacket.c.
2005 * Process the DISCONNECT packet through scheduler in the
2006 client library. Affected file lib/silcclient/client.c.
2008 * Fixed the silc_client_packet_parse to not to increase
2009 the packet sequence number if the conn->sock and the
2010 current socket connection is not same. This can happen
2011 for example during key agreement when the conn includes
2012 multiple socket connections (listeners). Affected file
2013 lib/silcclient/client.c.
2015 * The sender of the file transfer request now provides also
2016 the pointer (listener) for the key exchange protocol. If
2017 the listener cannot be created then it sends empty key
2018 agreement and lets the receiver provide the listener.
2020 Added `local_ip' and `local_port' arguments to the
2021 silc_client_file_send. If they are provided they are used,
2022 if not then it will attempt to find local IP address, if
2023 not found or bind fails then the remote client will provide
2026 Affected files are lib/silcclient/client_ftp.c and
2027 lib/silcclient/silcapi.h.
2029 * Extended the FILE SEND command to support defining the
2030 local IP and port for key exchange listener. They are
2031 optional. Affected file irssi/src/silc/core/silc-servers.c.
2033 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Defined to WHOIS command reply the sending of fingerprint
2036 of the client's public key (if the proof of posession of the
2037 corresponding private key is verified by the server).
2038 Updated to the protocol specification.
2040 * Added support of receiving the client's public key's
2041 fingerprint in command reply in client library. Affected
2042 file is lib/silcclient/command_reply.c, and
2043 lib/silcclient/idlist.[ch].
2045 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Do not send over 128 chars long nickname to the server
2048 in NICK command. Affected file lib/silcclient/command.c.
2050 * Do not send over 256 chars long channel names to the server
2051 in JOIN command. Affected file lib/silcclient/command.c.
2053 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Assure that silc_server_close_connection cannot be called
2056 twice for same socket context. Affected file is
2059 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * Send error message to application if opening file for
2062 writing during file transfer fails. Affected file is
2063 lib/silcclient/client_ftp.c.
2065 Remove all file transfer sessions for a client that we're
2066 removing from ID cache.
2068 Affected file is lib/silcclient/client_ftp.c.
2070 * Fixed silc_net_addr2bin to return correct address. Affected
2071 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2073 * Fixed file transfer session removing on signoff notify.
2074 Affected file irssi/src/silc/core/silc-servers.c.
2076 * Added the SilcClientFileError to be returned in the monitor
2077 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2078 Affected file lib/silcclient/silcapi.h.
2080 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Fixed a crash in silc_client_ftp_free_sessions and
2083 silc_client_ftp_session_free_client. Affected file
2084 lib/silcclient/client_ftp.c.
2086 * Added `disabled' field in the SilcChannelEntry in the server
2087 to indicate if the server entry is disabled. Affected file
2088 silcd/idlist.h, silcd/command[_reply].c.
2090 * SILC server adds now /var/run/silcd.pid everytime it is
2091 started. Affected file silcd/silcd.c.
2093 * Added silc_server_packet_send_clients to send a packet to
2094 the provided table of client entries. Affected file
2095 silcd/packet_send.[ch].
2097 * Fixed a crash in client resolving in client_prvmsg.c in
2098 client library. Affected file lib/silcclient/client_prvmsg.c.
2100 * Do not actually remove the client directly from ID cache
2101 during SERVER_SIGNOFF, but invalidate it. This way we
2102 preserve the WHOWAS info for the client. Affected file
2103 silcd/server_util.c.
2105 * Fixed SERVER_SIGNOFF notify handling in the server. The
2106 server is now able to process incoming SERVER_SIGNOFF notify
2107 for a server that it doesn't even know about. It will remove
2108 the clients provided in the notify. Affected file
2109 silcd/packet_receive.c.
2111 * Check for partial packet in data queue after every packet that
2112 was found from the queue. Return and wait for more data if
2113 there is partial data in queue. Affected file is
2114 lib/silccore/silcpacket.c.
2116 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * Added SilcClietFileError enum to indicate error in
2119 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2120 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2121 Affected files lib/silcclient/silcapi.h and
2122 lib/silcclient/client_ftp.c.
2124 * Check that newsize in silc_buffer_realloc is larger than
2125 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2127 * Added better monitor of file transfers. It now monitors
2128 key agreement protocol during the file transfer too. Added
2129 error reporting too. Affected files
2130 irssi/src/silc/core/silc-servers.c,
2131 irssi/src/fe-common/silc/module-formats.[ch].
2133 * Wrote a help file for FILE command.
2135 * Added silc_rng_global_get_byte_fast to get not-so-secure
2136 random data as fast as possible. Random data is read from
2137 /dev/urandom if available and from the SILC RNG if not
2138 available. It is used in padding generation. Affected file
2139 lib/silccrypt/silcrng.[ch].
2141 * All packets in client library are now processed synchronously.
2142 Optimized packet processing a lot. Affected file
2143 lib/silcclient/client.c.
2145 * All server connection packets are processing synchronously
2146 now in server, to optimize packet processing. Affected file
2149 * Include files are installed now only in Toolkit distribution
2150 if make install is given. Affected files: all Makefile.am's.
2152 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Assure that silc_client_notify_by_server_resolve does not
2155 resolve the client information multiple times. If it cannot
2156 be found by the first it cannot be found at all. Affected
2157 file lib/silcclient/client_notify.c.
2159 * Fixed WHOWAS command reply calling. Affected file
2160 lib/silcclient/command_reply.c.
2162 * Removed all references to silc_idlist_get_client from the
2163 Irssi SILC client since that call is internal call used by
2164 the library. The Irssi SILC client will use now client
2165 retrieval functions found in silcapi.h.
2167 * Fixed a bug in resolving nickname info before sending
2168 private message. It used freed memory. Affected file
2169 irssi/src/silc/core/silc-servers.c.
2171 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Assure my_channels statistics cannot go negative in server.
2174 Affected files silcd/server.c, silcd/server_util.c.
2176 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2190 * Added silc_net_localip to return local host's IP address.
2191 Affected file lib/silcutil/silcnet.[ch].
2193 * If key exchange or rekey protocol is active for a connection
2194 parse all packets syncronously since there might be packets
2195 in packet queue that we are not able to process without first
2196 processing packets before them. Affected file silcd/server,
2197 lib/silcclient/client.c.
2199 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2200 whether library should continue processing the packet.
2201 Affected file lib/silccore/silcpacket.h.
2203 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2232 lib/silcutil/silcutil.[ch].
2234 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Resolve the client info when received private message or
2237 channel message for a client which nickname we don't know.
2238 Affected files lib/silcclient/client_prvmsg.c and
2239 lib/silcclient/client_channel.c.
2241 * Do not crash in /KEY if client is not connected. Affected
2242 file irssi/src/silc/core/silc-channels.c.
2244 * Added SilcClientStatus field to the SilcClientEntry in the

2247 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2248 is incomplete and is being resolved, it won't be resolved
2251 Make sure also that USERS command reply does not resolve
2252 twice information. Affected file is
2253 lib/silcclient/command_reply.c.
2255 Make sure that silc_client_get_clients_by_list does not
2256 resolve twice same information.
2258 * Check for valid client->id in the silc_server_free_client_data.
2259 Affected file silcd/server.c.
2261 * Fixed /GETKEY nick@server not to crash if the server entry
2262 is not found. Affected file lib/silcclient/command.c.
2264 * Fixed the silc_server_check_cmode_rights to check the
2265 requested modes correctly. Affected file silcd/command.c.

2269 * Better checks for non-printable chars in nick added.
2270 Affected file silcd/command.c.
2272 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Call the silc_server_udpate_servers_by_server in the
2275 primary router that comes back online in the backup resuming
2276 protocol. Otherwise it routes packets wrong. Affected file
2277 silcd/server_util.[ch], silcd/server_backup.c.
2279 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2282 lib/silcutil/silcbuffmt.[ch].
2284 * Redefined the SILC packet header to include the padding
2285 length. Affected file lib/silccore/silcpacket.[ch].
2287 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2288 length for maximum padding up to 128 bytes). Affected
2289 file lib/silccore/silcpacket.h.
2291 * Removed all backwards support for old 0.5.x MAC thingies.
2292 The SILC packet header change makes it impossible to be
2293 backwards compatible.
2295 * Send the ENDING packet with timeout in the backup resuming
2296 protocol. This is to assure that all routers has connected
2297 to the primary router. Affected file silcd/server_backup.c.
2299 * Changed the RNG to take the first IV from random data. It
2300 used to take it from zero actually. Changed the RNG also
2301 to use /dev/urandom during session. /dev/random is used
2302 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2304 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Changed the SILC packet header to have the first two bytes
2307 (the packet length) encrypted. Affected files aroung the
2308 code tree, lib/silccore/silcpacket.[ch]. Removed the
2309 SilcPacketCheckDecrypt callback. It is not needed anymore
2310 since the silc_packet_receive_process will determine now
2311 whether the packet is normal or special.
2313 * Implemented the unidirectional MAC keys. Affected files
2314 lib/silcske/silcske.c, silcd/protocol.c and
2315 lib/silcclient/protocol.c.
2317 * Implemented the packet sequence number to the MAC computation.
2318 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2319 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2320 lib/silcclient/protocol.c.
2322 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2324 * Allow backup router to announce servers. All servers
2325 announced by backup router are added to the global list
2326 automatically. Update hte server's socket to our primary
2327 router also when backup router announces a server.
2328 Affected file silcd/packet_receive.c.
2330 * Do not update the client->router in the function
2331 silc_server_udpate_clients_by_server if the client is on
2332 global list. We might fail to find any specific server
2333 for locally connected clients and local cell clients. They
2334 should still use the `from' and not `to' as client->router.
2335 This fixes backup router resuming protocol. Affected file
2336 silcd/server_util.c.
2338 * Decrease channel statistics count only if the channel
2339 deletion worked. Affected files are silcd/server.c and
2340 silcd/server_util.c.
2342 * Added silc_server_update_servers_by_server to update origin
2343 of all server entries. Used during backup router protocol.
2344 Affected files silcd/server_util.[ch], silcd/server.c. and
2345 silcd/backup_router.c.
2347 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2348 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2349 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2350 lib/silccrypt/silchmac.c.
2352 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Assure that router cannot reroute the same channel message
2355 to the sender. Affected file silcd/packet_receive.c.
2357 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Made better checks that the channel message is not sent
2360 to the router it came from. Affected file is
2361 silcd/packet_send.c. Fixed memory leak too.
2363 * Announce informations for incoming router connection, but
2364 only after checking if it is replaced by backup router.
2365 Affected file silcd/packet_receive.c.
2367 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Fixed the backup resuming protocol to work in multiple
2370 router environment. Affected file silcd/server_backup.c.
2372 * Route packet only to one router in the function
2373 silc_server_packet_send_to_channel. Affected file is
2374 silcd/packet_send.c.
2376 * Fixed silc_server_send_notify_dest to set the broadcast
2377 flag. Fixed the silc_server_send_notify_topic to actually
2378 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2379 Affected file silcd/packet_send.c.
2381 * Changed the SFTP Filesystem interface. Changed the
2382 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2383 the filesystem operation function. The SilcSFTPFilesystem
2384 is now a context that is allocated by all filesystem allocation
2385 functions and it already includes the operations structure
2386 and filesystem specific context. It is given as argument
2387 now to the silc_sftp_server_start. This made the interface
2388 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2389 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2391 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Changed the backup router adding and getting interfaces
2394 in the server. The router that will be replaced by the
2395 specified backup router is now sent as argument. Affected
2396 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2399 * Added silc_net_addr2bin_ne to return the binary form of
2400 the IP address in network byte order. Affected files
2401 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2403 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Check for existing server ID in silc_server_new_server
2406 and in silc_server_connect_to_router_final and remove the
2407 old entry if it exists. Affected file silcd/packet_receive.c,
2410 * Send the channel message always to only one router, either
2411 in upstream or downstream. Affected file is
2412 silcd/packet_send.c.
2414 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2416 * Wrote the definition of the backup resuming protocol to the
2417 protocol specification.
2419 * Removed one redundant channel key generation from normal
2420 server during joining procedure. Removed one redundant
2421 channel key sending from server to router during joining
2422 procedure. Affected file silcd/command.c.
2424 * Made minor bugfixes to the backup router resuming protocol.
2425 Affected file silcd/server_backup.c, server.c.

2430 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2433 * Implemented the backup resuming protocol that is used to
2434 resume the primary router position in the cell after the
2435 primary router comes back online. Affected files
2436 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2437 and silcd/server_util.[ch].
2439 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Sleep two (2) seconds after sending QUIT command to server.
2442 Affected file lib/silcclient/command.c.
2444 * Assure that if outgoing data buffer is pending do not force
2445 send any data. Affected file silcd/packet_send.c.
2447 * Assure that if outgoing data buffer is pending do not force
2448 send any data. Affected file lib/silcclient/client.c.
2450 * Implemented the backup router support when the primary router
2451 goes down. The servers and routers can now use the backup
2452 router as new primary router without loosing connectivity.
2454 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2457 in the server to indicate disabled entry. All data read
2458 from the connection will be ignored and no data is sent
2459 for entry that is disabled. Affected files are
2460 silcd/idlist.h, silcd/server.c.
2462 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Created SFTP client and server test programs in the
2465 lib/silcsftp/tests directory.
2467 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Implemented memory filesystem (virtual filesystem) for
2470 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2473 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Implemented the SFTP (SSH File Transfer Protocol) to the
2476 lib/silcsftp. It includes SFTP client and SFTP server
2479 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Moved lib/silccore/silcprotocol.[ch] to the
2482 lib/silcutil library.
2484 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2485 take variable argument list pointer as argument. Affected
2486 file lib/silcutil/silcbuffmt.[ch].
2488 * Added silc_buffer_set function that is used to set data
2489 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2490 Affected file lib/silcutil/silcbuffer.h.
2492 * Changed various routines in the core library to use the new
2493 silc_buffer_set instead of allocating new buffer only for
2496 * Added 64-bit value formatting and unformatting support to the
2497 silc_buffer_[un]format routines. Affected file is
2498 lib/silcutil/silcbuffmt.[ch].
2500 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2501 to includes/bitmove.h.
2503 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Fixed channel user mode saving in client library. Affected
2506 file lib/silcclient/command[_reply].c.
2508 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Defined the file transfer to the SILC Protocol. Added
2511 new packet type SILC_PACKET_FTP and defined File Transfer
2512 Payload. The mandatory file transfer protocol is SFTP
2513 (SSH File Transfer Protocol). Affected file in addition
2514 of the internet draft is lib/silccore/silcpacket.h.
2516 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2517 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2518 is used as part of backup router protocol when the primary
2519 router of the cell is back online and wishes to resume
2520 the position as primary router.
2522 * Redefined the MAC generation keys in the protocol. The
2523 same key is not used anymore in both direction. Both
2524 direction will now use different keys for sending and
2525 receiving. This fixes a potential security flaw. This
2526 change causes incompatibilities in the protocol.
2528 * Redefined also the MAC computation from the packet.
2529 An packet sequence number is now added to the MAC
2530 computation. This prevents possible replay attacks against
2531 the protocol. This change too causes incompatibilities
2534 Added `sequence' field to the SilcPacketContext to hold
2535 the current sequence number for the packet.
2537 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Added `created' field to the SilcIDListData in the file
2540 silcd/idlist.h to indicate the time when the entry was
2543 * Added `created' field to the SilcChannelEntry too. Affected
2544 file silcd/idlist.h.
2546 * Added `creation_time' aguments to all the announcement functions
2547 in the server. If it is provided then only the entries that
2548 was created after the provided time frame are actually
2549 announced. Affected file silcd/server.[ch].
2551 * The protocol says that the Channel ID's IP address must be
2552 based on the router's IP address. Added check for this in
2553 the silc_server_new_channel when processing incoming New Channel
2554 Payload. Affected file silcd/packet_receive.c.
2556 * Print out the correct version with --version in SILC client.
2557 Affected file irssi/src/silc/core/silc-core.c.
2559 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Fixed WHOWAS command to check for completnes of the client
2562 entry always, not just when the command is coming from client.
2563 Affected file silcd/command.c.
2565 * Added new function silc_server_packet_queue_purge to purge the
2566 outgoing data queue to the network. After the function returns
2567 it is guaranteed that the outgoing packet queue is empty.
2568 Affected file silcd/packet_send.[ch].
2570 * Purge the outgoing packet queue in the rekey protocol's final
2571 callback to assure that all rekey packets go to the network
2572 before quitting the protocol. Affected file silcd/server.c.
2574 * Added silc_client_packet_queue_parse as similar function as
2575 in server to the client library. The affected file is
2576 lib/silcclient/client.c.
2578 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Splitted silcd/server.c and created silcd/server_util.[ch]
2581 for utility functions.
2583 * Added new socket flag SILC_SF_DISABLED to indicate that the
2584 connection is open but nothing can be sent to or received from
2585 the connection. Affected file lib/silcutil/silsockconn.[ch].
2586 The checking for disabled socket is checked in the low level
2587 silc_socket_write and silc_socket_read functions.
2589 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * Allow only nicknames and channel names that fits into the
2592 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2594 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * When processing JOIN command reply in server check that if
2597 the channel exists in our global list we'll move it the local
2598 list. Affected file silcd/command_reply.c.
2600 * Fixed the check whether client is joined on the channel already
2601 in JOIN command. Affected file lib/silcclient/command.c.
2603 * Fixed the JOIN command reply to check whether the channel
2604 already exists. Affected file lib/silcclient/command_reply.c.
2606 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Added silc_ske_status_string to map the SKE error numbers
2609 to readable strings. The affected files are
2610 lib/silcske/silcske[_status].[ch].
2612 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Do not show the private channels on the WHOIS channel list
2615 as it is not allowed by the protocol. The affected file is
2618 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Assure that the packet length digged from the actual packet
2621 is something sensible in the silc_packet_decrypt_rest_special
2622 in lib/silccrypt/silcpacket.c.
2624 * Free and NULL the allocated pointer in silc_hmac_alloc if
2625 the HMAC allocation fails. The affected file is
2626 lib/silccrypt/silchmac.c.
2628 * Print the selected security properties to the log files in
2629 the server. Affected file silcd/protocol.c.
2631 * Add SKE's reference counter even if calling the completion
2632 callback manually. Otherwise it goes negative, although it
2633 does not cause any problems. The affected file is
2634 lib/silcske/silcske.c.
2636 * Remove the client entry with short timeout after giving the
2637 KILL command. Affected file lib/silcclient/command.c.
2639 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2640 case all found clients are already disconnected (WHOWAS would
2641 found them) in the server. Affected file silcd/command.c.
2643 * Update the last_receive (time of last data received) to be
2644 updated only when received private or channel message so that
2645 the idle time showed in WHOIS makes more sense.
2647 * Added boolean field `valid' in to the SilcClientEntry in the
2648 client library to indicate whether the entry is valid or not.
2649 This fixes the nickname change bug on channel when changing
2650 the nickname to be same than the old (like nick to Nick) the
2651 nickname formatter doesn't set the new nick anymore to Nick@host.
2652 Affected file lib/silcclient/idlist.[ch].
2654 * Now actually fixed the nickname changing on disconnection.
2655 Added new function silc_change_nick to the Irssi SILC Client.
2656 Affected file irssi/src/silc/core/client_ops.c,
2657 irssi/src/silc/core/silc-nicklist.[ch].
2659 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Check that the public key exists in the GETKEY command before
2662 trying to encode it. Affected file silcd/command.c.
2664 * Print some notifications on received public keys with GETKEY
2665 command in the Irssi SILC Client. Affected files are
2666 irssi/src/fe-common/silc/module-formats.[ch],
2667 irssi/src/silc/core/client_ops.c.
2669 * Use IDENTIFY command to resolve the server information in the
2670 GETKEY command instead of INFO command. Affected file
2671 lib/silcclient/command.c.
2673 * All command reply functions in the client library now calls
2674 the pending command reply callbacks even if an error has
2675 occurred. The server has done this a long time and now it was
2676 time to move the client library to this as well. Now all
2677 errors can be delivered back to the pending command reply
2678 callbacks if necessary. Affected files are
2679 lib/silcclient/command[_reply].[ch].
2681 * Change the nickname on disconnection back to the username
2682 because in reconnect the server will enforce it to it anyway.
2683 Affected file irssi/src/silc/core/silc-servers.c.
2685 * Fixed a config file parsing bug in the Irssi SILC client.
2686 Affected file irssi/src/silc/core/clientconfig.c.
2688 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * When printing the channel mode on JOIN, verify that the
2691 channel key and channel's HMAC are valid. Affected file
2692 irssi/src/silc/core/client_ops.c.
2694 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2697 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2698 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2700 * Removed channel key rekey task deleting from the function
2701 silc_server_save_channel_key. Affected file silcd/server.c.
2702 Added explicit timeout task context instead that is used to
2703 delete the task if we are registering a new task before the
2704 new task has elapsed.
2706 * When channel key rekey occurs the client library now saves
2707 the old channel key for a short period of time (10 seconds) and
2708 is able to use it in case some is still sending channel
2709 messages encrypted with the old key after the rekey. Affected
2710 file lib/silcclient/[idlist.h|client_channel.c].
2712 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Added check to the silc_server_new_id_real to not accept
2715 new ID if it is the sender's own ID. Affected file is
2716 silcd/packet_receive.c.
2718 * Assure that we do not announce ourself or the one we've
2719 sending our announcements when we're router and are announcing
2720 servers to our primary router. Affected file silcd/server.c.
2722 * Fixed silc_server_command_identify_check_client to assemble
2723 correct WHOIS packet. It send corrupted WHOIS packet and
2724 caused problem with router to router connections. Affected
2725 file silcd/command.c.
2727 Fixed also silc_server_command_whois_check the same way
2728 as for the IDENTIFY command.
2730 * Added new SilcIDListStatus to the server in the SilcIDListData
2731 structure. The status now includes the current status of
2732 the entry (like registered, resolved etc.). Affected file
2733 silcd/idlist.[ch]. Defined a bunch of different status types
2734 as well. This replaced the old boolean registered field as well.
2736 Added resolve_cmd_ident field to the SilcClientEntry structure
2737 too so that if the entry is for example being resolved so
2738 another command may attach to the same pending command reply
2739 without requiring to resolve the same entry again. This concept
2740 should optimize the WHOIS and the IDENTIFY resolving under
2741 heavy load by taking away unnecessary resolving for entries
2742 that are being resolved already.
2744 Added support for adding multiple pending commands for one
2745 command idenfier. Affected file silcd/command[_reply].[ch].
2747 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2748 before deleting the data. Otherwise the hash table will have
2749 freed data in comparison functions. Affected file is
2750 silcd/command_reply.c.
2752 * Fixed silc_idlist_replace_client_id to add the new entry to
2753 the cache with NULL nickname. Otherwise there will be invalid
2754 memory as the nickname after the nickname is freed. Affected
2755 file silcd/packet_receive.c.
2757 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2758 saved into wrong slots because the previous number of entries
2759 was not taken into account. Affected file silcd/idlist.c.
2760 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2762 * If we are router and we receive JOIN notify to a channel that
2763 does not have any users then notified client is marked as the
2764 channel founder, as it is it. The affected file is
2765 silcd/packet_receive.c
2767 * Added to the extended hash table API's table_del_*ext functions
2768 the destructor as argument too, so that the caller can decide
2769 which destructor to use or whether to use destructor at all.
2770 Affected file lib/silcutil/silchashtable.[ch].
2772 * Fixed ID Cache purging. It actually deleted the entries from
2773 the hash table after the data was freed. The hash table ended
2774 up comparing freed memory. The affected file is
2775 lib/silccore/silcidcache.c.
2777 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Fixed Irssi SILC client's KILL command's HELP syntax.
2781 * The USERS command now resolves the detailed user information
2782 if the userinfo field is missing. Affected file is
2783 lib/silcclient/command_reply.c.
2785 * Do not print error in silc_file_read if the read file does
2786 not exist. Just silently return NULL. Affected file is
2787 lib/silcutil/silcutil.c.
2789 * Fixed the silc_log_output to not wine about NULL filename
2790 and to not create some bogus " " filename. Affected file is
2791 lib/silcutil/silclog.c.
2793 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Fixed various printing bugs on the user interface in the
2796 Irssi SILC Client. Minor changes that were forgotten from
2799 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2801 * Fixed the configure.in.pre and the compilation and distribution
2802 environment to support the new autoconf 2.52. That version is
2803 now required to compile the CVS trunk.
2805 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2808 to generally parse user@fqdn format strings. Affected file
2809 lib/silcutil/silcutil.c.
2811 * Added nickname_format and nickname_force_format fields to the
2812 SilcClientParams structure. The first one defines the format
2813 for the nicknames that the library will enforce if the receives
2814 multiple same nicknames. The second one is boolean value and
2815 can be used to force the library to always enforce the format
2816 to the nicknames regardles whether there are multiple nicknames
2817 or not. This configurable formatting was employed to flexibly
2818 support accessing multiple nicknames from the user interface.
2819 The userinterface can now set the nicknames to what ever format
2820 they prefer. Affected file lib/silcclient/silcapi.h.
2822 Added function silc_client_nickname_format to the file
2823 lib/silcclient/idlist.c. It performs the nickname formatting.
2825 Added new field `hostname´ to the SilcClientEntry context.
2826 It holds the hostname of the client. Affected file is
2827 lib/silcclient/idlist.h.
2829 * Irssi SILC Client sets the nicknames in nick@hostn format.
2830 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2831 irssi/src/silc/core/silc-core.c.
2833 The WHOIS printing now also shows both the real nickname and
2834 the formatted nickname so that user knows how to access the
2835 user if there are multiple same nicknames cached. Affected
2836 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2837 printing formatting too to take the hostname now as a separate
2838 argument. The Affected file is
2839 irssi/src/fe-common/silc/modules-formats.[ch].
2841 * Changed the silc_client_get_clients_local to accept the formatted
2842 nickname as argument. It accepts the real nickname too but the
2843 formatted nickname can be used to find the true entry from
2844 multiple entries. Affected file lib/silcclient/silcapi.h and
2845 lib/silcclient/idlist.c.
2847 * Added nickname_format_parse field to the SilcClientParams.
2848 It is a callback function provided by the application to parse
2849 the nickname out of the formatted nickname string. The library
2850 calls it to get the nickname from the formatted string. Since
2851 the application generally knows better the format of the nickname
2852 string it parses it instead of the library, even though library
2853 encodes the formatted string. If the callback function is not
2854 provided then the library will use the string as is. The
2855 affected file is lib/silcclient/silcapi.h.
2857 * All the nickname strings passed to the client library in
2858 commands are now expected to be formatted nickname strings.
2859 If the command does not support the formatted nickname string
2860 it will assume that the sent string is the actual nickname.
2861 Affected file lib/silcclient/command.c.
2863 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Added public key authentication support to OPER and SILCOPER
2866 commands in the client library. Affected file is
2867 lib/silcclient/command.c.
2869 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Changed the get_auth_methdod client operation to be asynchronous.
2872 It can be async if the application resolves the authentication
2873 method from the server during the negotiation. Added new
2874 SilcGetAuthMeth completion callback that the application will
2875 call after resolving the authentication method.
2877 Added function silc_client_request_authentication_method that
2878 the application can use to resolve the authentication method
2879 from the server. Added also SilcConnectionAuthRequest callback
2880 that the library will call after the server has replied. The
2881 application can call this function if it does not know the
2882 current authentication method.
2884 Affected files are lib/silcclient/client.c and
2885 lib/silcclient/silcapi.h.
2887 * The Irssi SILC client now automatically resolves the authentication
2888 method incase any configuration information is not present (and
2889 currently there never is). The affected file is
2890 irssi/src/silc/core/client_ops.c.
2892 * Fixed public key authentication from the client library.
2893 Affected file lib/silcclient/protocol.c. Changed also the
2894 protocol specification about the public key authentication in
2895 the connection authentication protocol. The actual data to be
2896 signed is now computed with a hash function before signing.
2898 * Fixed the public key authentication from the server as well.
2899 Affected file silcd/protocol.c.
2901 * Removed the mlock()'s from the memory allocation routines.
2902 Affected file lib/silcutil/silcmemory.c. The ./configure does
2903 not check anymore for the mlock(). Affected file is
2906 * Fixed USERS command in server to allow the execution of the
2907 command for private and secret channels if the client sending
2908 the command is on the channel. Affected file silcd/command.c.
2910 * Fixed silc_client_get_clients_local to return the clients
2911 count correctly. It could return wrong value. Affected file
2912 lib/silcclient/idlist.c.
2914 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2917 types. The assembler optimizations seemed not to like 64-bit
2918 data types. The assmebler optimizations thus are now enabled
2919 also for BSD systems as opposed to only enable them for Linux.
2921 * Do not check for threads at all on BSD systems. Affected
2922 file configure.in.pre.
2924 * Removed -n and -h options from the Irssi SILC Client since
2925 they are not used in silc.
2927 * Fixed the prime generation to assure that the first digit
2928 of the generated random number is not zero since our conversion
2929 routines does not like number strings that starts with zero
2930 digit. If zero digit is seen the random number is regenerated.
2931 This caused some corrupted RSA keys when the zero first digit
2932 was met. Affected file lib/silcmath/silcprimegen.c.
2934 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2936 * Fixed WIN32 configuration in the ./configure script.
2937 Fixed to include xti.h on environments that has it.
2938 Patches by Carsten Ilchmann and andrew.
2940 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Changed the silc_id_create_client_id to be collision
2943 resistant. It is now assured that there cannot be created
2944 two same client ID's. I suspect that some weird bugs in
2945 the server were actually caused by duplicate Client IDs.
2946 Affected file silcd/serverid.[ch]. A router receiving
2947 new ID now also assures and informs the sending server
2948 if the ID caused collision.
2950 * Changed the silc_id_create_channel_id to also assure that
2951 there are no collisions.
2953 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Statement about ignoring the Mutual Authentication flag when
2956 performing rekey with PFS was a bit misleading. It is ignored
2957 if it was set in the initial negotiation, it cannot be even
2958 set in the rekey. Fixed in the ke-auth draft. Started the
2959 new versions of the protocol drafts in the doc/.
2961 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Fixed a bug in silc_client_command_identify_save when saving
2964 new channel information. The channel name was no duplicated
2965 and caused crash on exit. Affected file is
2966 lib/silcclient/command_reply.c.
2968 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Fixed the getkey command handling in the server. Send just
2971 empty OK reply to the sender if the key could not be fetched
2972 (but everything else was ok, like the key just was not available).
2973 Changed the public key parameter to optional in the protocol
2974 specs so that empty OK reply can be sent. Affected file
2977 Added a message to Irssi SILC client to tell to user if the
2978 server did not return a public key.
2980 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2982 * Fixed a channel key regeneration bug. It registered new
2983 timeout tasks exponentially until all system resources were
2984 used. Affected file silcd/server.c.
2986 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Added the SILC Document generator to the scripts/silcdoc.
2989 It can be used to generate the Toolkit Reference Manual out
2990 of the source tree. Internally it will also use the RoboDoc
2991 generator now imported in util/robodoc.
2993 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Added couple of return's in rekey protocol if error orccurred
2996 during the protocol. The execution must be terminated.
2997 Affected file silcd/protocol.c. Also, terminate the protocol
2998 always with timeout.
3000 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * The client's Client ID was created initally from the wrong
3003 nickname (it could have been in format nick@host) in the
3004 silc_server_new_client. Affected file silcd/packet_receive.c
3006 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Added some SILC_LOG_ERROR's to various error conditions
3009 if client could not be added to ID cache. Affected files
3010 silcd/packet_receive.c and silcd/server.c.
3012 * When client's sock->user_data is freed, NULL also the
3013 client->router and client->connection pointers. Added check
3014 for these pointers being NULL to various places around the
3015 code. Affected file silcd/server.c.
3017 * Added client->data.registered == TRUE checks to various
3018 places around the code to assure that unregistered client's
3019 are not handled when it is not allowed. Affected file
3022 * Added `bool registered' fields to all
3023 silc_idlist_[server|client]_get_* routines to indicate whether
3024 the fetched client needs to be registered or not. Affected
3025 file silcd/idlist.[ch].
3027 * Add your own entry as registered to the ID cache in the
3028 server. Affected file server.c.
3030 * Fixed a bug in silc_server_new_server. The SilcServer was
3031 set as the new server's context instead of SilcServerEntry.
3032 This naturally caused some weird bugs.
3034 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Do not delete the channel rekey task when adding it
3037 for in silc_server_create_channel_key.
3039 * Changed the silc_server_create_channel_key to return
3040 TRUE or FALSE to indicate the success of the channel key
3043 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Fixed MSVC++ project files and added missing files to
3046 Makefiles under win32/.
3048 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Do not add TCP_NODELAY flag if the operating system
3051 does not have it defined. Affected files are
3052 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3054 * Fixed buffer overflow from Irssi SILC Client. Affected
3055 file irssi/src/fe-common/core/themes.c.
3057 * Fixed double free in client library in the file
3058 lib/silcclient/client.c when disconnecting from server.
3060 * Applied double free patch from cras to Irssi SILC client.
3061 Affected files irssi/src/core/[modules/expandos].c
3063 * Fixed the disconnection handling to Irssi SILC Client.
3064 The application must call silc_client_close_connection
3065 in ops->connect client operation in case of failure of
3066 the connection. Affected file is
3067 irssi/src/silc/core/client_ops.c.
3069 * Do not set sock->protocol to NULL in the function
3070 silc_client_close_connection after executing the protocol's
3071 final callback since the sock might not be valid anymore.
3072 Affected file lib/silcclient/client.c.
3074 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3076 * Do not enable SILC_THREADS if the linking with libpthread
3077 did not happen. Affected file configure.in.pre.
3079 * Added notion to protocol specification that server must
3080 verify the sent authentication payload with CMODE when
3081 setting the channel founder key. Implemented it to the
3082 server. Affected file silcd/command.c.
3084 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Added _EXTRA_DIST SILC distribution variable to the
3087 distributions file. It is used to conditionally add extra
3088 files or directories to the specific distribution. Affected
3089 files ./prepare, Makefile.am.pre and distributions.
3091 Removed the `_' from the start of the distribution names.
3094 * Added README.WIN32 for instructions to compile the Toolkit
3097 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3099 * Fixed a double free in disconnection in the server. Affected
3100 file is silcd/server.c.
3102 * Fixed the lib/silcske/groups.c to work now also with GMP
3103 MP library. The string conversion did not work when using
3104 specific base and the base is indicated in the string as well.
3106 * Created win32/ directory which now includes MSVC++ specific
3107 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3108 It will appear only in the toolkit distribution
3110 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Changed the key material distribution function in case when
3113 the hash output is too short. The data is now concatenated
3114 a bit differently than it used to. Made the change to the
3115 SKE protocol specification.
3117 * Added better GMP detection to configure.in.pre. A patch
3120 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Fixed a minor bug in SKE that might cause some problem on
3123 some platforms. Affected file lib/silcske/silcske.c.
3125 * Added the cookie checking for initiator in the SKE. It checks
3126 that the responder returns the sent cookie unmodified. The
3127 affected file is lib/silcske/silcske.c. Added new SKE
3128 error type INVALID_COOKIE that can be sent during the
3129 negotiation. Fixed some memory leaks as well.
3131 * Added the "invalid cookie" error message to Irssi SILC client's
3134 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * Added `task_max' field to the SilcClientParams to indicate
3137 the maximum tasks the scheduler can handle. If set to zero,
3138 default values are used. Affected file lib/silcclient/silcapi.h.
3140 * Fixed memory leaks in silc_client_close_connection. Affected
3141 file lib/silcclient/client.c.
3143 * Added silc_client_del_client_entry to client library to free
3144 all memory of given client entry. Affected file is
3145 lib/silcclient/idlist.[ch].
3147 * Added new functions silc_client_del_channel and
3148 silc_client_del_server to delete channel and server entries.
3149 Affected file lib/silcclient/[silcapi.h/idlist.c].
3151 * Removed silc_client_del_client_by_id from silcapi.h.
3153 * Fixed the INFO command to return the server's own info
3154 correctly when querying by Server ID. Affected file is
3157 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Removed the non-blocking settings in WIN32 code in the
3160 silc_sock_[read/write] and added SleepEx instead. Affected
3161 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3162 of input data is now checked with FIONREAD and ioctlsocket.
3164 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Call silc_schedule_task_del_by_context in the
3167 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3168 Affected file lib/silccore/silcprotocol.c.
3170 * Call silc_protocol_cancel for active protocols in the
3171 silc_server_close_connection if the funtion
3172 silc_server_free_sock_user_data has not been called.
3173 Affected file silcd/server.c.
3175 * Generic tasks cannot be deleted using the del_by_fd
3176 task deleting function since generic tasks does not match
3177 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3179 * Added a notion to SILCOPER help file that the SILCOPER works
3180 only on router server, not on normal server.
3182 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Added for WIN32 support for the new scheduler as well.
3185 Affected file lib/silcutil/win32/silcwin32schedule.c.
3187 * Fixed the SHA1 implementation to work on various platforms.
3189 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3192 API. It is part of the scheduler now. Everything else is
3193 as previously but some functions has changed their names.
3194 Checkout the lib/silcutil/silcschedule.h for the interface.
3195 Updated all applications to use the new interface. Affected
3196 files are lib/silcutil/silcschedule.[ch].
3198 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Found a bug in the SKE implementation. The HASH value,
3201 specified by the protocol, was not computed correctly. The
3202 public key of the responder was not added to the computation
3203 even though it is mandatory. Affected file lib/silcske/silcske.c.
3204 This unfortunately causes incompatibilities with older
3205 clients and servers.
3207 * Added WIN32 specific network init and uninit functions:
3208 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3209 the Winsock2. Affected file lib/silcutil/silcnet.h and
3210 lib/silcutil/win32/silcwin32net.c.
3212 * Set the socket always to nonblocking mode on WIN32 after
3213 reading data or writing data. Affected file is
3214 lib/silcutil/win32/silcwin32sockconn.c.
3216 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3218 * Fixed various compilation problems under WIN32. Affected
3219 files lib/silcutil/win32/silcwin32thread.c and
3220 lib/silcutil/win32/silcwin32schedule.c.
3222 * Removed all _internal.h #includes from public header
3223 files. Internal headers must never be included from
3226 Removed also the lib/silcske/payload_internal.h file.
3228 * All include files that may be needed (public and some others
3229 included by the public headers) by application developers are
3230 now copied to the ./includes directory. It does not copy any
3231 internal headers. Affected file Makefile.defines.pre and all
3232 Makefile.am's under lib/ and subdirs.
3234 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Do not change the ~/.silc directory's permissions automatically.
3237 Affected file irssi/src/silc/core/clientutil.c.
3239 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Do not cancel the protocol in silc_server_close_connection
3242 it might cause recursion. Now cancelled in the function
3243 silc_server_free_sock_user_data. Affected file silcd/server.c.
3245 * Fixed the silc_server_remove_clients_by_server to regenerate
3246 the channel keys correctly finally. Added also new function
3247 silc_server_remove_clients_channels to actually do it.
3248 Affected file silcd/server.c.
3250 * Fixed the silc_server_new_channel to not crash by giving
3251 wrong router to the new channel. Affected file is
3252 silcd/packet_receive.c.
3254 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3256 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3257 which is given as argument to the silc_client_alloc now.
3258 It can be used to configure the client and set various parameters
3259 that affect the function of the client.
3261 * The USERS command in server did not check whether the channel
3262 is private or secret. Affected file silcd/command.c.
3264 * Added new argument to the USERS command in protocol specification.
3265 The USERS command now can take the channel name as argument
3266 as well. Added support for this in client and server and
3267 updated the protocol specs.
3269 * Completed the GETKEY command in client. It can be now used
3270 to fetch also servers public key not only some clients.
3271 Affected files lib/silcclient/command[_reply].c.
3273 * Added silc_client_get_server to return server entry by the
3274 server name. Affected files lib/silcclient/silcapi.h and
3277 * Redefined the IDENTIFY command in protocol specification to be
3278 more generic. It now can be used to query information about
3279 any entity in the SILC Network, including clients, servers and
3280 channels. The query may be based either the entity's name
3281 or the ID. Added support for this in both client and server.
3283 Affected files silcd/command.c and lib/silcclient/command.c
3284 and command_reply.c.
3286 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3287 the _from_client and _from_server functions. Affected file
3290 * Added silc_client_get_channel_by_id_resolve to the file
3291 lib/silcclient/silcapi.h to resolve channel information by
3292 its ID. Added also silc_client_get_channel_by_id that
3293 does not resolve it from the server.
3295 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Added SilcServerEntry context into the client library
3298 to represent one server. The INFO command now allocates
3299 these to save the resolved server info. For now on the
3300 client library will also keep information about servers,
3301 connected and resolved with INFO.
3303 The INFO command now allocates the SilcServerEntry context
3304 and saves the server info there. The COMMAND_REPLY in
3305 the INFO now returns the parameters to application in
3306 same order as defined in the protocol specification.
3308 The entries are cached in the client->server_cache.
3310 * The INFO command is now issued after received the Client ID
3311 from the server. Affected file lib/silcclient/client.c.
3313 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3314 to the application as the mode changer might be server.
3315 It is guaranteed that NULL is not returned anymore to the
3316 application. Affected file lib/silcclient/client_notify.c.
3318 The ID Type is now also passed to the application so that
3319 it can check whether the returned entry is SilcClientEntry
3322 Added new function silc_client_get_server_by_id to return
3323 the server entry by ID. Affected files are the
3324 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3326 * Do not create the channel in the Irssi SILC Client when issuing
3327 the JOIN command but when received the sucessful JOIN command
3328 reply. Otherwise the channel might get created even though we
3329 could not join it. The Affected file is
3330 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3332 * Fixed a channel joining bug in router. The router must also
3333 check the channel modes, invite and ban lists etc. when serving
3334 the JOIN command sent by normal server. Affected file is
3335 silcd/command.c. The router now resolves the client's
3336 information from the server who sent the JOIN command if it
3337 does not know it, and processes the JOIN command only after
3340 * Changed the SilcCommandCb to take new argument; void *context2.
3341 Affected file lib/silccore/silccommand.h
3343 The second argument in the command callbacks in the server now
3344 includes the SilcServerCommandReplyContext if the command was
3345 called as pending command callback from the command reply.
3346 Otherwise it is NULL. When called as pending the status of the
3347 command reply will be checked and if it was erronous the
3348 error will be sent to the original sender of the command.
3349 This way the client always receives the error messages even
3350 though the server was actually the one who received the error
3351 when it resent the command to router, for example. Affected
3352 files silcd/command[_reply].[ch].
3354 * Fixed sending WHOWAS command's error message to client if
3355 the requested client could not be found. It was missing.
3358 * Changed the CMODE and CUMODE commands reply arguments in the
3359 protocol specification. The Channel ID is now sent in both
3360 of the commands to identify the channel. Implemented this
3361 new feature to the client and server. Affected files
3362 lib/silcclient/command_reply.c and silcd/command.c.
3364 * Made better checks for invite and ban lists in the JOIN
3365 command in server. Affected file silcd/command.c.
3367 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * The server now performs the incoming host IP/DNS lookup
3370 using the silc_socket_host_lookup and thus does not block
3371 the server anymore. Affected file silcd/server.c.
3373 * Completed the multi-thread support for SILC Scheduler in
3374 the lib/silcutil/silcschedule.c.
3376 * Fixed the configure.in.pre to detect the pthread correctly
3379 * Fixed a deadlock in silc_task_queue_wakeup in the file
3380 lib/silcutil/silctask.c.
3382 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3384 * Added new function silc_schedule_wakeup that is used in
3385 multi-threaded environment to wakeup the main thread's
3386 schduler. It needs to be used when a thread adds a new task
3387 or removes a task from task queues. After waking up, the
3388 scheduler will detect the task queue changes. If threads
3389 support is not compiled in this function has no effect.
3390 Implemented the wakeup mechanism to both Unix and WIN32
3391 systems. Affected files are lib/silcutil/silcschedule.[ch],
3392 lib/silcutil/unix/silcunixschedule.c and the
3393 lib/silcutil/win32/silcwin32schedule.c.
3395 * Added new function silc_task_queue_wakeup to wakeup the
3396 scheduler by the specified task queue. Affected file
3397 lib/silcutil/silctask.[ch].
3399 * The silc_socket_host_lookup_start now wakes up the scheduler
3400 after adding the timeout task. Affected file is
3401 lib/silcutil/silcsockconn.c.
3403 * The silc_socket_host_lookup is synchronous now if the threads
3404 support is not compiled in. However, the callback is still
3405 called asyncronously through the scheduler, anyway. Affected
3406 file lib/silcutil/silcsockconn.c.
3408 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3410 * Added new function silc_socket_host_lookup to perform
3411 asynchronous IP and FQDN lookups for the socket connection.
3412 Affected files lib/silcutil/silcsockconn.[ch].
3414 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3417 that may or may not compile the mutex support in.
3419 Changed the silc_mutex_alloc interface. It allocates the
3420 mutex now to the sent pointer and returns TRUE or FALSE.
3422 Affected file lib/silcutil/silcmutex.h.
3424 * Wrote the SILC Task Queue interface to support multi-threads.
3425 Affected file lib/silcutil/silctask.[ch].
3427 * Wrote the SILC Scheduler to support multi-threads. Affected
3428 file lib/silcutil/silcschedule.c.
3430 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3433 in lib/silcutil/win32/.
3435 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Defined SILC Mutex API and SILC Thread API and implemented
3438 them for Unix. Affected files are
3439 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3440 lib/silcutil/unix/silcunixmutex.c and
3441 lib/silcutil/unix/silcunixthread.c.
3443 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Fixed the silc_server_remove_clients_by_server's channel
3446 key re-generation. The hash table handling was incorrect
3447 and would not work with many channels. Affected file is
3450 * Fixed some memory leaks around the server code.
3452 * Rewrote the silc_server_get_users_on_channel to support IPv6
3453 based Client ID's. Affected file silcd/server.c.
3455 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3456 specification. However, a separate document must be written
3457 to define the detailed signing procedure and the payload
3458 associated with the flag. Defined the flag to the
3459 lib/silccore/silcchannel.h as well.
3461 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Changed the dynamic tables to static size tables in the
3464 lib/silccrypt/silchmac.c.
3466 * Removed GCC dependencies from the code. A patch by cras.
3468 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3470 * Do not show the error "Error receiving packet bla bla"
3471 in server if it really was not an error (-2 means that reading
3472 is pending). Affected file silcd/server.c.
3474 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3476 * Fixed a possible crash in silc_server_remove_clients_by_server
3477 in silcd/server.c. Fixed there also some memory leaks.
3479 * Fixed the silc_idlist_replace_client_id. It could replace
3480 wrong key in the hash table. Affected file silcd/idlist.c.
3482 * Do not check whether there are global users on the channel
3483 if the channel->global_users is FALSE. Affected functions
3484 silc_server_remove_from_one_channel and
3485 silc_server_remove_from_channels in silcd/server.c. Also,
3486 do not check if the removed client is local as we can be
3487 sure that global client was not removed from the channel
3488 and checking for global users is not needed.
3490 * The silc_server_remove_clients_by_server now re-generates
3491 the channel keys correctly for those channels that had
3492 clients removed from them. Affected file silcd/server.c.
3494 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3496 * Found the reason of random crashes in the server. We weren't
3497 ignoring the SIGPIPE signal (which can be sent in write())
3498 and it crashed the server. Affected file silcd/silcd.c.
3500 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3502 * Assure that sock->user_data is not NULL in the function
3503 silc_server_packet_send in silcd/packet_send.c.
3505 * Disconnect the remote connection if it could not be added
3506 to any ID lists in the server. The affected file is
3509 * Check in silc_server_packet_send[_real/dest] that the
3510 socket is not disconnecting and ignore the data if it is.
3511 Affected file silcd/packet_send.c.
3513 * Define inline to __inline on native WIN32 compilation.
3514 Affected file includes/silcwin32.h.
3516 * Added some explicit type casts for inline code since MSVC
3517 require them. Affected files lib/silcutil/silcbuffer.h,
3518 lib/trq/silcdlist.h and lib/trq/silclist.h.
3520 * Print warning in log files from now on if the packet
3521 decryption fails. Affected file silcd/server.c.
3523 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3525 * Changed the `say' client operation's interface to accept
3526 new `type' argument to indicate the type of the message sent
3527 by the library. The application may filter the library's
3528 messages according the type. The affected file is the
3529 lib/silcclient/silcapi.h.
3531 * Added two new functions to lib/silcclient/silcapi.h:
3532 silc_client_del_client and silc_client_del_client_by_id.
3533 Affected file lib/silcclient/idlist.c.
3535 * Moved the clientincludes.h from includes/ to silc/ and
3536 serverincludes.h from includes/ to silcd/.
3538 * The modes for the CMODE and CUMODE are now passed as
3539 uint32 for application with COMMAND_REPLY. The affected
3540 file is lib/silcclient/command_reply.c.
3542 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * /WHOIS without arguments shows client's own information.
3545 Affected file lib/silcclient/command.c.
3547 * Changed PING to not accept any arguments. The specs
3548 says that client can ping only the connected server so
3549 requiring an argument is not needed. Affected file is
3550 lib/silcclient/command.c.
3552 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Fixed a fatal bug in private message sending and reception
3555 encryption and decryption when using private message keys.
3556 The implementation was incorrect and did not follow the
3557 specification. It causd that some of the message were
3558 lost since it did not use the sending and receiving keys
3559 as the protocol suggests. This has been fixed and will cause
3560 incompatibilities with older clients when sending private
3561 message encrypted with private message keys. Affected files
3562 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3563 and various other in Irssi SILC Client.
3565 Added `responder' boolean argument to the functions
3566 silc_client_add_private_message_key[_ske] to indicate when
3567 the key is added as responder or initiator of the key
3570 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Removed the silc_ske_check_version function and created
3573 a SilcSKECheckVersion callback. Added also a function
3574 silc_ske_set_callbacks that is now used to set all SKE
3575 callbacks. The callback functions are not given to
3576 the SKE functions anymore, but this function is used to
3579 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3581 * Added `silc_version' argument to the silc_client_alloc
3582 to define the version of the application for the library.
3583 The library will use the version string to compare it
3584 against the remote host's (usually a server) version
3585 string. Affected file lib/silcclient/silcapi.h
3587 * Added the KE protocol context to Key Agreement context
3588 in client library so that we can abort the SKE if it
3589 is in process when we get timeout. Affected file is
3590 lib/silcclient/client_keyagr.c.
3592 * Do not resolve the client ID forever if it returns in the
3593 first time that such client does not exist. This was done
3594 for example with private message. Affected file is
3595 lib/silcclient/client_prvmsg.c.
3597 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3599 * Do not add regex.h for WIN32. The affected file
3600 includes/silcincludes.h.
3602 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3603 not work yet 100%. It generates the DLL's automatically
3604 when compiling with --with-win32 under cygwin.
3606 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * lib/contrib/regex.c is not compiled on WIN32.
3610 * Added silc_net_get_socket_opt function to the
3611 lib/silcutil/silcnet.h.
3613 * Added includes/silcwin32.h for WIN32 specific includes
3616 * Do not use ptime structure or any of the posix process
3617 functions on WIN32 in lib/silccrypt/silrng.c.
3619 * Added silc_gettimeofday to provide generic function
3620 for struct timeval on all platforms. Added the function
3621 to lib/silcutil/silcutil.h.
3623 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3625 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3626 library as they clearly belong there. As a plus side we
3627 can make the actual socket connection routines platform
3630 Added also new generic function silc_socket_read and
3631 silc_socket_write (that used to be silc_packet_[read/write].
3632 The implementation of these are platform specific.
3634 * Added WIN32 specific routines of silc_socket_[read/write]
3635 to lib/silcutil/win32/silcwin32sockconn.c.
3637 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * Added preliminary support for native WIN32 compilation under
3640 cygwin (using the -mno-cygwin option for GCC) to the
3641 ./configure.in.pre. The --with-win32 now prepares the
3642 compilation for native WIN32.
3644 * Rewrote the SILC Scheduler interface in the file
3645 lib/silcutil/silcschedule.h. The scheduler is now context
3646 based and does not have anymore any global static scheduler.
3647 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3648 and created lib/silcutil/win32 directory for WIN32 based
3651 * Added Unix specific network routines to the
3652 lib/silcutil/unix/silcunixnet.c and the old
3653 lib/silcutil/silcnet.c includes now only generic routines.
3655 Added WIN32 specific network routines to the
3656 lib/silcutil/win32/silcwin32net.c.
3658 * Added Unix specific utility functions from the
3659 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3661 * Added WIN32 SILC Scheduler to the file
3662 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3665 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Do not handle JOIN notify in the server if the target client
3668 is not registered (idata->registered == FALSE). The affected
3669 file is silcd/packet_receive.c.
3671 * Update the nickrec->founder in event_cumode in the Irssi SILC
3672 client. Affected file irssi/src/silc/core/silc-channels.c.
3674 * Fixed the CUMODE_CHANGE notify handling in the server when
3675 server and router are announcing their clients on channels.
3676 Now the mode changes are saved and notified correctly. The
3677 affected file is /silcd/packet_receive.c.
3679 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3680 They really did not replace the cache entry in the ID Cache.
3681 Now they do that. Affected file silcd/idlist.c.
3683 * Fixed the KICK notify handling in the Irssi SILC client to
3684 update the channel records so that the kicked client does not
3685 appear to be on the channel. The affected file is
3686 irssi/src/silc/core/silc-channels.c.
3688 * Always update the conn->current_channel when executing command
3689 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3691 * Fixed the KILL notify handling in Irssi SILC client to remove
3692 the killed client on all channels.
3694 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Fixed the silc_parse_command_line to remove extra spaces
3697 from the start and end of the arguments. Affected file is
3698 lib/silcutil/silcutil.c.
3700 * Cancel and free any active protocol in the function
3701 silc_server_close_connection. Affected file silcd/server.c.
3703 * Cancel and free any active protocol in the function
3704 silc_client_close_connction. Affected file is
3705 lib/silcclient/client.c.
3707 * Do not execute the KILL command for clients that are in
3708 history (ie. they are not in the network). Affected file is
3711 * Fixed KILL notify handling, client does not crash anymore.
3712 Affected file irssi/src/silc/core/silc-channels.c.
3714 * Reduced the default packet buffer size from 2048 to 1024 in
3715 lib/silccore/silcpacket.c.
3717 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3718 counter to the SKE context that is incresed when the SKE library
3719 performs async operation outside the library. If the outside
3720 process frees the SKE context and FREED status will be set
3721 and the library will detect after the sync operation that the
3722 libary is freed. The affected files are
3723 lib/silcske/silcske[_status].[ch].
3725 * Resolve the client entry information in the function
3726 silc_client_channel_message to assure that NULL pointer is not
3727 passed as client entry to the application. */
3729 * Fixed the task timeout calculation to assure that there is
3730 never negative timeouts. The affected file is
3731 lib/silcutil/silcschedule.c.
3733 * Fixed the channel user mode notification sending in server.
3734 It was sent point-to-point to the router (or to server by router)
3735 but it needs to be destined to a channel. The routines now
3736 supports sending the channel user mode notifys to the channels
3737 when announcing clients and channels. Affected files are
3738 silcd/server.c and silcd/packet_receive.c.
3740 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3741 It did not actually replace the old channel entry in the cache.
3742 Affected file lib/silcclient/client_notify.c.
3744 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Fixed a possible crash in silc_packet_send_prepare. It now
3747 assures always that there is enough space in the buffer and
3748 at the tail area of the buffer (for MAC).
3750 Fixed the inbound buffer reallocation in silc_packet_read.
3751 It was old code and did not handle the reallocation correctly.
3754 The affected file is lib/silccore/silcpacket.c.
3756 * Fixed buffer overflow in silc_parse_nickname in the file
3757 lib/silcutil/silcutil.c.
3759 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * make install generates new server keys only if there is not
3764 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3767 Added check that if the NOREPLY is set then we will not send
3768 the away message. This avoids infinite loop of away messages
3769 if both clients are away. The affected file is
3770 lib/silcclient/client_prvmsg.c.
3772 * Fixed client crash if /NICK was given without arguments.
3773 Affected file lib/silcclient/command.c.
3775 * Server does not send the invite list in INVITE command back
3776 to the client if the list was not altered. Added this notion
3777 to the protocol spec as well. Affected file silcd/command.c.
3779 Fixed possible crash in INVITE command by checking the
3780 value of silc_server_get_client_route command.
3782 * Fixed the INVITE notify type handling. The arguments are now
3783 taken in correct order and client does not crash. The affected
3784 file is irssi/src/silc/core/silc-channels.c.
3786 Removed the "Inviting xxx to channel" message from the
3787 client library away and let the application handle it.
3788 Affected file lib/silcclient/command.c. Added that message
3789 to Irssi SILC client's message formats.
3791 * Fixed CMODE command crash in client. It now checks the
3792 amount of arguments correctly and does not crash. The affected
3793 file is lib/silcclient/command.c.
3795 * Do not create new channel automatically in silc_channels_join
3796 but check whether the channel by that name already exists.
3797 Affected file irssi/silc/core/silc-channels.c.
3799 * Do not send the SERVER_SIGNOFF to router if the disconnected
3800 entity was the router. Affected file silcd/server.c.
3802 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3803 SILC client as it was missing from there.
3805 Added the handling of the KICK notify to the Irssi SILC client
3806 as it was missing. Added "you have been kicked" message to
3807 Irssi SILC client's message modules formats.
3809 Added the handing of the KILL notify to the Irssi SILC client
3810 as it was missing. Added the kill message module formats
3813 The affected file is irssi/src/silc/core/silc-channels.c.
3815 * The router did not save the channel mode the server announced.
3816 Affected file silcd/packet_receive.c.
3818 * Fixed a possible crash in INFO command in server. If the
3819 server did not provide the server info it crashed. Affected
3820 file silcd/command.c.
3822 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Fixed the GETKEY command in the server to check also the
3825 global list. Otherwise the GETKEY would not work correctly
3826 in normal SILC server. Affected file silcd/command.c.
3828 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Fixed GETKEY crash, it crashed if the command did not succseed.
3832 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3835 is now real and not just an macro interface to GMP.
3837 Removed the entire GMP from the source tree and imported new
3838 NSS MPI library instead. Reason for removing GMP is that it is
3839 extremely large and compiles extremely slow. The NSS MPI
3840 is only a few files and compiles in less than 10 seconds.
3841 The speed is also about the same as GMP. The MPI is imported
3842 to lib/silcmath/mpi.
3844 If the system has GMP installed we will still use the GMP.
3845 If it is not then the NSS MPI will be compiled.
3847 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Merged a long nickname (127 characters long) crash bugfix from
3850 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3852 * Merged a freed memory reference bugfix from Irssi CVS tree.
3853 Affected file irssi/src/core/commands.c.
3855 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Added the server's public key sving and verification to the
3858 server when performing the SKE. This was missing and the
3859 remote server's (or router's) public key was accepted without
3860 checking whether we have it previously or trust it at all.
3861 Affected file silcd/protocol.c.
3863 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Check in the silc_server_timeout_remote if protocol is active
3866 and make sure that the protocol's final callback is called so
3867 that all memory if freed. Affected file silcd/server.c.
3869 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * silc_server_whois_send_reply crashed the server if the nickname
3872 was 127 characters long. Affected file silcd/command.c.
3874 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added sanity check to the silc_server_new_client. If the hostname
3877 is provided inside username then check that the provided hostname
3878 really is the same as the resolved one. If the hostname was not
3879 resolved then check it from the public key. Affected file is
3880 silcd/packet_receive.c.
3882 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3883 if the server disconnected us and the connection is not valid
3884 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3886 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3887 the library to the lib/silcutil/silcutil.[ch].
3889 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3891 * Close log file after open. Affected file
3892 lib/silcutil/silclog.c.
3894 * Check whether sock == NULL in silc_client_send_packet and return
3895 if it is. Affected file lib/silcclient/silcclient.c.
3897 * Check rec->entry == NULL in the Irssi SILC Client before
3898 sending the channel message. Affecte file is
3899 irssi/src/silc/core/silc-servers.c.
3901 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Merged a splitted window bugfix from Irssi CVS tree. The
3904 affected file is irssi/src/fe-text/textbuffer-view.c.
3906 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3907 It did not print nickname.
3909 * Improved the distributions system a bit.
3911 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3914 irssi/src/fe-text/gui-window.c.
3916 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3917 to in-active server. The affected file is
3918 irssi/src/silc/core/client_ops.c.
3920 * Resolve the client in USERS command reply if the entry does
3921 not have username resolved. The affected file is
3922 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3923 command to WHOIS command to really resolve stuff. The USERS
3924 is not used any more in any critical section so WHOIS can
3925 be used even though it might be slower than IDENTIFY.
3927 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3930 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Changed the protocol API a bit more consistent in the
3933 lib/silccore/silcprotocol.[ch].
3935 * Changed the following headers to ROBODoc format:
3937 lib/silccore/silcpayload.h
3938 lib/silccore/silcprotocol.h
3939 lib/silccore/silcsockconn.h
3941 All core library headers are now formatted.
3943 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Fixed a bug in Irssi SILC client; do not show that you are
3946 server/router operator if you really are not. Affected file is
3947 irssi/src/silc/core/client_ops.c.
3949 * Renamed silc_command_free_payload to silc_command_payload_free.
3950 Affected file lib/silccore/silccommand.h
3952 * Added silcmath.h to include the prototoypes of various routines
3953 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3956 * Changed the following headers to ROBODoc format:
3958 lib/silccore/silcchannel.h
3959 lib/silccore/silccommand.h
3960 lib/silccore/silcid.h
3961 lib/silccore/silcidcache.h
3962 lib/silccore/silcmode.h
3963 lib/silccore/silcnotify.h
3964 lib/silccore/silcpacket.h
3965 lib/silcmath/silcmath.h
3967 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Added checking to the server code not to start the server if
3970 ciphers and stuff are not configured properly. Affected files
3971 silcd/serverconfig.[h] and silcd/server.c.
3973 * Changed the layout of the header files of the public interfaces
3974 in the SILC libraries. The new layout supports ROBODoc
3975 documentation tool (and some others) so that it is easy to create
3976 a library reference manual. All the other headers and source
3977 code must still follow the CodingStyle document. Also source
3978 code must not include these ROBODoc stuffs, only the headers.
3979 Furthermore, all public interface headers must now be named
3980 by using `silc' prefix, example: silcapi.h, silccipher.h.
3981 Some files were renamed due to this. All the other headers
3982 must not be used as public interfaces. I will update the
3983 CodingStyle document later. Changed following headers, so far:
3985 lib/silcclient/silcapi.h
3986 lib/silccore/silcauth.h
3987 lib/silccore/silcprivate.h
3988 lib/silccrypt/silcdh.h
3990 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Removed silc_client_packet_send_flush from the client library
3995 as it is not needed. Affected file lib/silcclient/client.[ch].
3997 * Added printing of message of unresolved authentication method
3998 to the Irssi SILC client. Added it to the module formats.
3999 Removed the same message from the client library.
4001 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Added new distribution feature, DISTLABEL. Every distribution
4004 can define own preprocessor label that can be used in the
4005 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4006 file distributions, acconfig.h.pre and prepare.
4008 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Added Makefile.defines_int to include the actual definitions
4011 for Makefile.defines.in. Tested the new distribution system,
4012 created distributions and tested installation.
4014 * Added AWAY message printing to the Irssi SILC client. Added
4015 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4017 * Added SCONNECT command to call the SILC's CONNECT command.
4018 Cannot use CONNECT directly since Irssi uses that internally.
4019 Affected file irssi/src/silc/core/silc-servers.c.
4021 Added ACTION local command. It is same as ME command but takes
4022 the channel as mandatory argument.
4024 Rewrote some of the Irssi's help files to suite for SILC
4027 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Added Makefile.defines[.in] that should for now on be included
4030 in all Makefile.am file in the source tree. That file includes
4031 all common compilation definitions for SILC source tree.
4033 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Minor changes to the ./prepare script to change the package
4036 name according the distribution name to the configure.in.
4038 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Created new distribution system. Added file `distributions'
4041 that defines all the distributions that can be created out of
4042 the SILC source tree. The ./prepare script now reads that
4043 file to determine how to prepare the distributions. The
4044 first argument to the ./prepare is the name of the distribution
4045 and second is the version of the distribution. If given
4046 without arguments it creates the default (toolkit) distribution
4047 with the default version (defined in ./prepare).
4049 All Makefile.am files that are subject to the distributions
4050 are now named as Makefile.am.pre. These are ./Makefile.am
4051 and lib/Makefile.am. Others may be changed later.
4053 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Added invite list, ban list, some key management and connection
4056 error message printing to module formats in the Irssi SILC client.
4058 * Added new silc_client_set_away_message to set the away message
4059 that is back to the person who sent private message. The
4060 affected file lib/silcclient/silcapi.h and the
4061 lib/silcclient/client_prvmsg.c.
4063 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Fixed the private message sending in the Irssi SILC client,
4066 added local command KEY to the Irssi SILC client.
4068 Added key management and key agreement message formats to the
4069 irssi/src/fe-common/silc/module-formats.[ch].
4071 Added USERS (alias WHO) printing, server/router operator
4072 indication and LIST command printing to the module formats.
4074 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Fixed channel joining notify handling, cumode notify handling
4077 from Irssi SILC client.
4079 * Added SILC specific module-formats to the Irssi SILC client so
4080 that SILC specific message hilighting, colors etc is possible.
4081 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4083 Added channel mode, channel user mode, actions, notices,
4084 whois and whowas printing to the the module-formats.c.
4086 * Fixed a bug in channel deletion in the server. The channel
4087 is not left to the cache even if the channel founder auth mode
4088 is set when there are no users anymore on the channel. Affected
4089 file silcd/server.c.
4091 * The silc_net_localhost now resolves the entire hostname including
4092 the domain name. Affected file lib/silcutil/silcnet.c.
4094 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Changed the ask_passphrase client operation to be ascynchronous.
4097 It has now a completion callback and a context that the
4098 application must call after it has got the passphrase from
4099 the user. Affected files lib/silcclient/silcapi.h,
4100 lib/silcclient/protocol.c, lib/silcclient/command.c and
4103 Added SilcAskPassphrase callback that the application calls
4104 to deliver the passphrase to the library.
4106 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4107 The public key verification and especially a certificate
4108 verification is asynchronous procedure.
4110 Added new SILC_SKE_STATUS_PENDING status to indicate the
4111 request is pending and a callback will be called to finalize
4114 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4115 indicate that remote end did not send its public key (or
4116 certificate), even though we require it. Added check for this
4117 condition in the SKE. This was a security bug, now fixed.
4119 Defined new SilcSKEVerifyCbCompletion callback that is called
4120 when the verification process is completed.
4122 The affected files lib/silcske/silcske_status.h and
4123 lib/silcske/silcske.[ch].
4125 * Changed the verify_public_key client operation to be async
4126 as well. Defined SilcVerifyPublicKey callback that is used to
4127 indicate the success of the public key verification process.
4129 Changed the server and client to use the new async client
4132 * Changed the Irssi SILC client's internal scheduler to be called
4133 twice as many times as it used to be. As a result the client
4134 should be a bit faster now. Affected file is
4135 irssi/src/silc/core/silc-core.c.
4137 * Added support to Irssi SILC client of asynchronous public key
4138 verification and passphrase inquiry. Affected file is
4139 irssi/src/silc/core/silc-core.c.
4141 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Do not say "You have left channel %s" in client library.
4144 Moved it to the application. Affected files are
4145 lib/silcclient/command.c and silc/client_ops.c.
4147 * Fixed silc_client_get_clients. Command context was not
4148 duplicated and was freed memory in the callback. Affected
4149 file lib/silcclient/idlist.c.
4151 * Do not say "you are now talking..." on JOIN command in the
4152 client library. The appliation must handle it.
4154 * Do not say ".. changed topic to" in command reply in the
4155 client libary. The application must handle it.
4157 * Fixed TOPIC command sending in the client library.
4159 * Fixed a memory leak in silc_client_command_free in the file
4160 lib/silcclient/command.c.
4162 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Imported a modified version of Irssi client to the source tree.
4165 The Irssi will be used to create a new client called
4166 Irssi SILC. Imported to irssi/.
4168 Added silc_core_init_finish function to the Irssi. Affected
4169 file irssi/configure.in.
4171 A lot changes in the Makefile.ams around the irssi tree.
4173 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Do not rehash if the new size is same as the old size of the
4176 hash table, in the silc_hash_table_rehash*. The affected file
4177 lib/silcutil/silchashtable.c.
4179 * Replaced hash_table_del_by_context calls from the server
4180 (when channel->user_list and client->channels) to the
4181 hash_table_del as it is sufficient and faster.
4183 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Added silc_hash_table_list, silc_hash_table_get and the
4186 SilcHashTableList structure to provide an alternative way to
4187 traverse the hash table. The affected files are
4188 lib/silcutil/silchashtable.[ch].
4190 * Changed the server's idlist routines to use the hash table
4191 routines to optimize the code.
4193 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Replaced the client entry's `channel' list and channel entry's
4196 `user_list' list to hash tables for optimized lookup. Changed
4197 the code to use the hash table interface around the code.
4198 Affected file lib/silcd/idlist.[ch].
4200 * Added `auto_rehash' boolean argument to the function
4201 silc_hash_table_alloc to indicate whether the hash table should
4202 auto-rehash when it thinks is appropriate time. It will
4203 increase the hash table size if the there is twice as much
4204 entries in the table than the size of the table, and will
4205 decrease the size if there are twice as less entries than
4206 the size of the table.
4208 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4212 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * silc_idcache_purge_by_context deletes the entry now by context
4215 as it is supposed to do. Affected file lib/silccore/idcache.c.
4217 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4218 client is not anymore valid (WHOWAS givens the info) and not
4219 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4221 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Removed the `data' and `data_len' arguments from the ID Cache
4224 interfaces and added `name' argument. ID Cache does not handle
4225 anymore the binary data only a names associated with given ID.
4227 * When hashing a Client ID with silc_hash_id the entire ID is
4228 not hashed anymore, instead only the hash of the Client ID is
4229 hashed. This way we can access the Client ID from the cache
4230 with Client ID but with the hash of the ID (which is a hash of
4231 the nickname) as well without any difference in performance.
4233 Added also silc_idcache_find_by_id_one_ext to do one on one
4234 searching when we have the actual ID. Added also function
4235 silc_hash_client_id_compare. The affected files are
4236 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4238 * When hashing the name associated with a ID it is always done
4239 in lowercase. This way we can access the cache without worrying
4240 about case-sensitivity, even though, for example nicknames are
4243 * Fixed a bug in server with channel message sending. It put
4244 wrong ID type as destination ID. The affected file
4245 silcd/packet_send.c.
4247 * silc_idcache_del_by_context now deletes from all hash tables
4248 by context. Affected file lib/silccore/idcache.c.
4250 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Changed the client library to use the new ID Cache interface.
4253 Changes around the source tree.
4255 * Added silc_hash_table_rehash_ext to rehash with specific
4256 hash function. Affected file lib/silcutil/silchashtable.[ch].
4258 * Added silc_hash_string_compare to compare two strings in the
4259 hash table. Affected file lib/silcutil/silcutil.[ch].
4261 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added new function silc_idcache_del_by_context into the
4264 lib/silccore/idcache.[ch].
4266 * Changed the server's ID list routines to use the new ID Cache
4267 interface. Changes around the source tree.
4269 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Added silc_hash_table_del[_by_context]_ext functions in to the
4272 lib/silcutil/silchashtable.[ch].
4274 Removed silc_hash_table_find_all* routines and added new
4275 silc_hash_table_find_foreach to replace them.
4277 Added silc_hash_table_replace_ext function as extended
4278 replacing function. Separated the simple hash table interface
4279 from the extended hash table interface in the file
4280 lib/silcutil/silchashtable.h.
4282 * Fixed minor bugs and changed it to use some of the new
4283 hash table functions in lib/silccore/idcache.c
4285 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Added new function silc_hash_table_find_all to return all keys
4288 in the hash table by the specified key. As the hash table is
4289 collision resistant it also makes it possible to have several
4290 duplicate keys in the hash table. This function may be used to
4291 find all of the keys from the hash.
4293 Added user_context arguments to the SilcHashFunction,
4294 SilcHashCompare and SilcHashDestructor to deliver user specified
4297 Added new fuctions silc_hash_table_find[_all]_ext to do
4298 extended lookup with specified hash and compare functions and
4299 specified user contexts.
4301 Added new function silc_hash_table_add_ext to add the key
4302 with specified hash function and user context.
4304 Added new function silc_hash_table_foreach to traverse all
4305 entrys in the hash table. Added SilcHashForeach callback
4308 Added new function silc_hash_table_del_by_context to delete
4309 the entry only if the context associated with the key matches.
4311 Affected files are lib/silcutil/silchashtable.[ch].
4313 * Removed silc_hash_[server/client/channel]_id and added just
4314 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4315 silc_hash_id_compare to compare two ID's using as the hash table
4316 comparison function. Added also silc_hash_data to hash
4317 binary data and silc_hash_data_compare to compare it.
4319 * Removed silc_idlist_find_client_by_hash as it is not needed
4320 anymore. Affected file silcd/idlist.[ch].
4322 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4323 to use internally the SilcHashTable. The new ID Cache is a lot
4324 faster than the old one. Some of the ID Cache interface was also
4325 rewritten and obsolete and stupid functions were removed.
4327 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Added entry_count field to the SilcHashTable to keep the number
4330 of the entries in the table. Implemented the function
4331 silc_hash_table_rehash. Added new function
4332 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4334 Fixed a minor bug in silc_hash_table_free.
4336 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4337 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4338 into the lib/silcutil/silcutil.[ch].
4340 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Implemented a collision resistant hash table into the
4343 lib/silcutil/silchashtable[ch]. See the header and the source
4344 for the SilcHashTable API.
4346 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Merged dotconf version 1.0.2 into lib/dotconf.
4350 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4352 * Do not compile anything in lib/silcsim/* if the SIM support
4353 is not enabled. The tree should now compile without problems
4356 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Compiled the SILC under cygwin. Compiled and tested briefly
4359 without problems. More tests needed. The SIMs didn't compile
4362 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4364 * Fixed possible crash in silc_get_username in the
4365 lib/silcutil/silcutil.c.
4367 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Fixed a va_arg in silc/client_ops.c.
4371 * Oops, RC5 routines were named AES and caused some problems
4372 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4374 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Added new SilcIDIP structure into the lib/silccore/id.h and
4377 replaced the old `ip' fields from all SILC ID's to that type.
4378 This is a step towards IPv6 support.
4380 The silc_id_get_len takes now the ID as an extra argument.
4381 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4382 both IPv4 and IPv6 based ID's.
4384 The affected files are lib/silccore/id.[ch] and other files
4385 around the tree using these routines.
4387 * Removed the ID length arguments in server from various
4388 silc_server_send_notify_* routines -> they are not needed
4391 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Fixed memory leak in silc_encode_pem_file in the file
4394 lib/silcutil/silcutil.c.
4396 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Check minor version as well in the SKE. Affected files are
4399 silcd/protocol.c and lib/silcclient/protocol.c.
4401 * Added --identifier option to the server so that an identifier
4402 can be when creating the public key for the server. Affected
4403 file is silcd/silcd.c.
4405 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4406 lib/silccrypt/silcpkcs.c.
4408 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Register default ciphers and stuff when using -C option with
4411 the server. Affected file sildc/silcd.c.
4413 * Put back the servers public key filename format, it is better
4414 than the new one. For now, the client keys are saved with the
4415 new filename format. The affected file silc/client_ops.c.
4417 * Implemented the Cipher API for the rest of the ciphers that
4418 did not implement it or implemented it the wrong way.
4420 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Register default ciphers and stuff when using the -S option
4423 in the client. Affected file silc/silc.c. Same also when
4424 creating new key pair with -C option.
4426 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Fixed the silc_verify_public_key client operation function to
4429 save the public keys differently. The fingerprint is now
4430 used as filename and not the hostname. This way also the
4431 client keys are saved uniquely and not with hostnames. The
4432 affected file is silc/client_ops.c.
4434 * Trimmed the silc_hash_fingerprint function to remove extra
4435 whitespaces from the end of the fingerprint. The affected
4436 file is lib/silccrypt/silchash.c.
4440 * Added silc_cipher_register_default function to register all
4441 default ciphers. It can be used when configuration files
4442 does not exist and the application does not want any specific
4443 ciphers in any specific order.
4445 The SilcDList is now used as silc_cipher_list dynamically
4446 allocated cipher list. Removed the static list all together
4447 and now all ciphers must be allocated to the dynamic list.
4448 The silc_cipher_alloc routine was changed to check only the
4451 All silc_cipher_* routines that used to return int returns
4454 The affected files lib/silccrypt/silccrypt.[ch].
4456 * The same thing was done to silc_hash_* as for silc_cipher_*
4457 routines. Affected files lib/silccrypt/silchash.[ch].
4459 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4460 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4461 Added also silc_pkcs_[un]register[_default] functions.
4462 Removed the data_context from the PKCS API.
4464 * Added silc_hmac_register_default function to register default
4465 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4466 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4467 to unregister all hmacs at once.
4469 * Register the default ciphers, hash functions, PKCSs and HMACs
4470 if client's configuration file does not exist. The affected
4473 * The client did not load the hash functions from the SIM
4474 modules at all. Added support for this. Affected file is
4475 silc/clientconfig.c.
4477 * When decoding public key with silc_pkcs_public_key_decode, check
4478 the supported algorithm only if PKCS are registered. Affected
4479 file lib/silccrypt/silcpkcs.c. The same was done with the
4480 silc_pkcs_private_key_decode.
4482 * Fixed the SILC List routines to keep the list always in order.
4483 It used to change the list's order when traversing the list but
4484 not it preserves the order. Affected file lib/trq/silclist.h.
4486 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4488 * Added the client library to use the SilcSocketConnection's
4489 reference counter (by silc_socket_dup) to prevent the bug that
4490 the socket object may be freed underneath async operation.
4492 * The name resolv library checking fixes in the configure.in.pre.
4495 * Created new version of the protocol drafts for future
4496 development. The -03 drafts are the ones that will be changed
4497 in the trunk now and the -02 will remain as they are.
4499 * Send list of CUMODE notifys to the router when announcing
4500 the channel users to the router. Affected file silcd/server.c.
4501 If the router receiving channel founder CUMODE for a channel
4502 that already has channel founder it will send CUMODE notify
4503 to the sender to remove the channel founder rights from the
4504 announced client. Affected file silcd/packet_receive.c.
4506 * The CUMODE notify may now use Server ID as well as the entity
4507 who changes the mode. Updated protocool specs.
4509 * Updated INSTALL and README files.
4511 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * New web pages in the http://silc.pspt.fi. The pages was
4518 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Implemented the [DenyConnectin] config section in the server.
4521 Added silc_server_config_denied_conn to check whether incoming
4522 connection is denied. Affected file silcd/serverconfig.[ch].
4524 * Do not check the ports when checking the incoming configuration
4525 data if the port is 0, meaning any. Affected file is
4526 silcd/serverconfig.c.
4528 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Fixed buffer overflow in silc_string_compare in the file
4531 lib/silcutil/silcutil.c.
4533 * Fixed double free in silc_server_command_leave in the file
4536 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Fixed the version checking in the server. Affected file is
4541 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Fixed the configuration data fetching when accepting new
4544 connections in the server. Affected file silcd/server.c.
4546 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Added `sender_entry' argument to the function
4549 silc_server_packet_relay_to_channel so that we can check
4550 whether some destination actually belongs to the same route
4551 the sender belongs (ie, we must not resend the packet to the
4552 sender). Affected file silcd/packet_send.[ch].
4554 * Added `servername' field to the SilcClientEntry in the server
4555 to hold the name of the server where client is from. Affected
4556 file is silcd/idlist.h.
4558 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Moved the channel message encrypting in the router betwen
4561 router connections from silc_server_channel_message to the
4562 silc_server_packet_relay_to_channel since we want to check
4563 whether we have anybody channel before encrypting anything.
4564 Affected files silcd/packet_[receive/send].c.
4566 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Fixed the [AdminConnection] server config section to support
4569 multiple entries. Affected file silcd/serverconfig.c.
4571 * Added support into the server to check the validity of the
4572 incoming connection before executing any KE or authentication
4575 * The connection configuration is now saved to the KE and
4576 connection auth protocol contexts and not fetched anymore in
4577 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4579 * The local hosts listenning address and port is also resolved
4580 now when starting the server. We want to have the socket object
4581 to include the real address and port for the listener. Added
4582 new function silc_net_check_local_by_sock into the files
4583 lib/silcutil/silcnet.[ch].
4585 * Fixed a broadcast bug in server -> do not broadcast if we
4588 * Fixed a routing bug. Do not route broadcast packets ever.
4589 Broadcast packets must be processed always and not routed since
4590 they may be destined to some other host than yourself and thus
4591 would get routed without no good reason. Affected file is
4594 * Added function silc_server_config_is_primary_route to check
4595 whether primary router connection has been configured (a router
4596 configuration that we are initiating). If there is not, we
4597 will assume that there is only two routers in the SILC network
4598 and we will use the incoming router connection as our primary
4599 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4601 * Changed the order of the broadcasting. Broadcast _after_ the
4602 packet has been processed not before. Affected file is
4605 * Fixed a [ClientConnection] parsing bug. The port was never
4606 parsed correctly thus resulting to port 0. Affected file
4607 silcd/serverconfig.c.
4609 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4610 argument and did not set the broadcast packet flag. Affected
4611 file silcd/packet_send.c. Fixed same bug in the function
4612 silc_server_send_notify as well.
4614 * If we receive NEW_ID packet for our own ID in the server, ignore
4617 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Removed the nickname from the Private Message Payload.
4622 Updated the code and the protocol specs.
4624 * Updated protocol specs for submitting to the IETF.
4626 * Tweaked the Random Number Generator a bit. Affected file
4627 lib/silccrypt/silcrng.c. Exported a new function
4628 silc_rng_[global]_add_noise which can be used to add more
4631 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Do not parse packets with different timeout when protocol
4634 is active -> may cause problem with rekey. Affected file
4637 * When server receives signoff notify it must not create
4638 new channel key if the client is on any channels since the
4639 sender of the signoff notify will create it.
4641 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added printing of error messages during SKE protocol from the
4644 failure packet sent by server during SKE. Affected file
4647 * Removed the client's failure_callback handling with timeout
4648 and handle it immediately when received.
4650 * The SKE library returned wrong type in SUCCESS and FAILURE
4651 packets. They must be 32 bit MSB not 16 bit MSB.
4653 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Ok, rewrote the logic of the re-key and now it seems to work.
4656 I tested it on high traffic with frequent re-keys without
4657 problems. Added hmac_receive (and renamed hmac to hmac_send)
4658 in SilcClientConnection in lib/silcclient/client.h and
4659 in SilcIDListData in silcd/idlist.h. Also, removed the
4660 SilcPacketParserContext's cipher and hmac fields as they are
4661 not needed anymore and actually caused some problems when
4662 the ciphers and hmac's changed underneath the packet parser.
4664 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * If re-key protocol is active then process the incoming packets
4667 synchronously since we must assure that icoming packets encrypted
4668 with the old key is processed before the new keys is set to
4669 use. This is true other packets than for REKEY packets.
4670 Affected file silcd/server.c. The same was done to client library
4671 as well, affected file lib/silcclient/client.c.
4673 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Fixed bug in client and server to accept the force send if
4676 the packet is send from silc_[server/client]_packet_process
4677 function. Otherwise the packets are never delivered, oops.
4679 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Disable force sending of packets when REKEY protocol is active.
4682 We must assure that no packet is sent directly when rekey is
4683 performed. All packets must be sent through packet queue.
4684 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4685 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4686 function is silc_[server/client]_packet_send_real to check
4689 * Replaced the SIM paths from example config files to
4690 /usr/local/modules. Also, make install creates now
4691 /usr/local/silc/logs directory to hold all the SILC server
4694 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Made the configure.in.pre work on Solaris. Patch by salo.
4698 * Made all ciphers compatible with non-x86 machines. Defined
4699 CBC mode macros into lib/silccrypt/ciphers_def.h.
4701 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Fixed the make install.
4705 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * When MAC computation fails the silc_packet_decrypt returned 0
4708 even though it was supposed to return -1. Fixed this. The
4709 affected file is lib/silccore/silcpacket.c.
4711 * Do not replace the config files in /etc/silc (in make install)
4712 if they already exist. Affected file ./Makefile.am.
4714 * Do not send re-key packets immediately but through packet queue.
4715 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4717 * Changed silc_net_check_host_by_sock to return FALSE if the
4718 IP/DNS could not be resolved. Though, it returns the IP address
4719 now even if it could not resolve it (but returns also FALSE).
4720 Affected file lib/silcutil/silcnet.[ch].
4722 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Added silc_pkcs_decode_identifier to decode the public key's
4725 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4726 Added also silc_pkcs_free_identifier. Added also new context
4727 SilcPublicKeyIdentifier.
4729 * Added -S option to the silc client. It is used to dump the
4730 contents of the specified public key file.
4732 * Changed the PKCS api to return the public key length when
4733 setting the public key.
4735 * Fixed a fatal bug in the public and private key file loading.
4736 Affected file lib/silccrypt/silcpkcs.c.
4738 * Execute the packet parsing for client with zero (0) timeout
4739 if the protocol is active. Affected file silcd/server.c.
4741 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Made the key generation options to the silcd program. Added
4744 -C option, equivalent to client's option.
4746 * Added new [ServerKeys] config section to the server. It
4747 configures the server's public and private key.
4749 * Defined generic Public Key Payload into the protocol
4750 specification to send specific type of public keys and
4753 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4754 public key or certificate.
4756 * Implemented the GETKEY command to the server and to the

4765 * Added SilcServerRekey context into silcd/idlist.h.
4767 * Added the PFS support as defined in the specification to the
4768 SKE protocol. Affected files lib/silcske/*.c.
4770 * Added `ske_group' field to the SilcServerRekey context to hold
4771 the number of the SKE group that is used with PFS in re-key.
4772 Affected file silcd/idlist.h.
4774 * Added PFS re-key support to the server. Affected file is
4777 * Added silc_protocol_cancel to cancel execution of the next
4778 state of the protocol. Affected file is
4779 lib/silccore/silcprotocol.[ch].
4781 * Added the re-key support with and without PFS to the client
4782 library. Re-key is performed once in an hour, by default.
4784 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4785 Added silc_client_rekey_callback and silc_client_rekey_final.
4786 Affected files are lib/silcclient/protocol.[ch] and
4787 lib/silcclient/client.[ch].
4789 * Removed the `hmac_key' and `hmac_key_len' fields from the
4790 SilcClientConnection structure; not needed. Affected file is
4791 lib/silcclient/client.h.
4795 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Do not ask whether user wants to use the negotiated private key
4798 for private messages, just use it. Affected file is
4799 silc/local_command.c.
4801 * Added `send_enc_key' and `enc_key_len' fields to the
4802 SilcIDListData structure since they are needed in the re-key
4803 phase. Affected file is silcd/idlist.[ch].
4805 * Implemented the simple re-key protocol into the server.
4806 Affected files silcd/server.c and silcd/protocol.[ch]. The
4807 re-key will be performed once in an hour, by default.
4809 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4810 Added silc_server_rekey, silc_server_rekey_callback and
4811 silc_server_rekey_final.
4813 * Removed Tunneled flag from the protocol. Updated the code
4814 and the specifications.
4816 * Adde `pfs' field to the SilcIDListData to indicate whether
4817 the PFS is to be performed in the re-key. Affected file is
4820 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4823 int64 of at least the xintXX size. If void * is less that 4
4824 bytes uint32 * will be used. Defined bool as boolean.
4826 * Changed _ALL_ unsigned long and unsigned int to uint32,
4827 unsgined short to uint16 in the source tree.
4829 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4830 not handle clients that has entry->data.registered == FALSE.
4831 They are not in the network anymore. Affected file is
4834 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Implemented the sending of the SERVER_SIGNOFF notify in the
4837 server. Affected file is silcd/server.c.
4839 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4840 Added also silc_notify_payload_encode_args into the
4841 lib/silccore/silcnotify.[ch].
4843 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4844 Affected file silcd/packet_receive.c.
4846 * Implemented the SERVER_SIGNOFF notify handling in the client
4847 library. Affected file lib/silcclient/client_notify.c. Also,
4848 implemnted the printing of the SERVER_SIGNOFF info to the
4849 application. Affected file silc/client_ops.c.
4851 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4852 if the deleting was successful. Affected file silcd/idlist.[ch].
4854 * Added support for public key authentication in the connection
4855 authentication protocol in the client library. Affected file
4856 lib/silcclient/protocol.c.
4858 * Changed the server's silc_idlist_get_clients_by_* interface
4859 to support already allocated array so that new entries may be
4860 added to pre-allocated array. Affected file silcd/idlist.[ch].
4861 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4862 and command replies.
4864 * All command reply functions in the server now calls the
4865 pending command callback even if error occured. This way the
4866 error will be delivered to the client as well. Affected files
4867 silcd/command.c and silcd/command_reply.c.
4869 * Fixed INFO command to return local server's info if no server
4870 was provided. Affected file lib/silcclient/command.c.
4872 * Removed RESTART command for good. Updated the code and the
4875 * Rewrote parts of the task system. It is a bit simpler now.
4876 Removed unsued task priorities. The affected files are
4877 lib/silcutil/silctask.[ch].
4879 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Moved the USERS printing from the library to the application.
4882 Affected files lib/silcclient/command.c and silc/client_ops.c.
4884 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Added channel key re-key support. The re-key is perfomed
4889 only by the router and is done once in an hour. Added `rekey'
4890 field to the SilcChannelEntry in the server. Affected files
4891 silcd/server.c and silcd/idlist.h.
4893 * Added silc_task_unregister_by_context into the file
4894 lib/silcutil/silctask.[ch].
4896 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Added SILC_UMODE_GONE mode to indicate when the client is not
4899 present in the SILC network. Added also support to the local
4900 command AWAY that will set this mode. Added support of showing
4901 "xxx is gone" in WHOIS command. The USERS command shows the
4902 gone status as well.
4904 * Fixed setting server and router operator privileges in the
4905 server's UMODE command. Affected file silcd/command.c.
4907 * Merged the SKE KE1 and KE2 payloads into one payload. The
4908 new KE payload is equivalent to the old KE2 payload.
4910 Cleaned up the SKE Start Payload parsing. It now uses the
4911 simple buffer unformatting to do the parsing. A lot faster
4914 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4915 to the SKE that is used to indicate whether both of the SKE
4916 parties should perform authentication. By default only the
4917 responder performs authentication. By setting this flag also
4918 the initiator must do authentication. By default it is unset
4919 since in normal SKE case, client to server connection, only
4920 the responder should do authentication. When doing SKE between
4921 two clients both should perform authentication. Updated the
4922 code and the protocol specs.
4924 * A little fix to IDENTIFY command in the server. Search the
4925 client first by hash not nickname. Affected file is
4928 * Fixed the silc_client_close_connection to support closing
4929 the client to client connections wihtout deleting too much
4930 data. Affected file lib/silcclient/client.c.
4932 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4933 are received if protocol used to be active but is not anymore
4934 the application would crash due to NULL pointer dereference.
4935 Affected files silcd/server.c and lib/silcclient/client.c.
4937 * Added `hash' field to the SilcClientConnection to include
4938 the hash function negotiated in the SKE protocol.
4940 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4941 to set the channel founder authentication data. A client can
4942 claim the founder rights later by providing the authentication
4943 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4944 This way the channel founder can regain the channel founder
4945 privileges even it is left the channel. This works only on
4946 local server and the client must be connected to the same
4947 server to be able to regain the founder rights. Updated the
4948 protocol specs accordingly.
4950 Added support to the CMODE command in the client to set the
4951 founder auth data. Read the README to see how to set it.
4953 Added support to the CUMODE command to claim the founder
4954 rights. Read the README to see how to do it.
4956 Added support for the founder authentication to the Channel
4957 Entry in the server. Affected file silcd/idlist.h.
4959 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4960 server's CMODE command. Affected file silcd/command.c.
4962 * Added the following new functions into lib/silccore/silcauth.[ch]:
4963 silc_auth_get_method and silc_auth_get_data.
4965 * The server now saves the remote hosts public key to the
4966 SilcIDListData pointer. Affected file silcd/protocol.c.
4968 * The normal server now does not remove the channel entry from
4969 the cache if the founder authentication data is set. It used
4970 to remove it if the founder was the last one on the channel on
4971 the server and left the channel. The auth data is saved and
4972 if the channel is re-joined later the old entry is used with
4973 the old auth data. Affected files silcd/command_reply.c and
4976 * Removed the `pkcs' field from the SilcIDListData structure
4977 in the server; it is not used. Affected file silcd/idlist.h.
4979 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Fixed packet processing on slow links. Partial packets were
4982 never re-processed because the incoming data buffer was cleared
4983 by the application. Application must not directly clear the
4984 sock->inbuf, the packet processing routines handle it. Fixed
4985 this in client library and in server.
4987 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Fixed the WHOIS and IDENTIFY send reply function to really
4990 check whether to send list or just one entry. Affected file
4993 * Cleaned up the LEAVE command's channel key distribution. The
4994 affected file silcd/command.c.
4996 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4997 can enforce the channel mode as well. In that case the ID
4998 includes the ID of the server. The code now enforces the
4999 mode change if the router have different mode than the server.
5001 * The notify client operation with CMODE_CHANGE notify can now
5002 return NULL client_entry pointer if the CMODE was not changed
5003 by client. Application must check for this.
5005 * Added <Server ID> argument to INFO command to support server
5006 info fetching by Server ID.
5008 * Added silc_server_announce_get_channel_users to get assembled
5009 packets of channel users of the specified channel. Affected
5010 file silcd/server.[ch].
5012 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5013 was freed underneath the ID Cache.
5015 * Re-announce clients when the server received CHANNEL_CHANGE
5016 notify from the router. Affected file silcd/packet_send.c.
5018 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5021 crashed since it did not handle the fact that there is no cipher
5022 called "3" and didn't check the error condition. Now fixed.
5024 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5025 flag. It can be used to send message requests.
5027 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Implemented the RESTART command in the client.
5031 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5032 notice type messages. Added notice printing to the user
5035 * The channel keys are not re-generated if the channel's mode
5036 is PRIVKEY, ie private key on the channel exists. Affected
5037 files silcd/server.c and silcd/command.c.
5039 * Fixed a little bug in channel message delivery when channel
5040 private keys are set in the server. Affected file is
5041 silcd/packet_send.c.
5043 * Changed the setting on channel->on_channel = TRUE from the
5044 silc_client_save_channel_key to the JOIN command reply. The
5045 key payload is not received if the private channel key is set.
5046 Affected file lib/silcclient/command_reply.c and the
5047 lib/silcclient/client_channel.c.
5049 * When the CMODE_CHANGE notify is sent and the channel private
5050 key mode is removed the channel key must be re-generated in
5051 other cells as well. Added this support for the router in the
5052 silcd/packet_receive.c.
5054 * Added new local command NOTICE to send notice message on
5055 channel. Affected file silc/local_command.[ch].
5057 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Added new local command ME to the client. It is used to send
5060 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5061 some action. Affected file silc/local_command.[ch].
5063 * Changed channel_message and private_message client operations
5064 to deliver the message flags to the application. Added also
5065 the `flags' arguments to the silc_client_send_channel_message
5066 and silc_client_send_private_message functions. Affected file
5069 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Redefined the Private Message Payload to support private message
5072 keys and to support the new private message flags. Updated
5073 the protocol specs. Flags makes it possible to have for example
5074 CTCP style messages.
5076 * Added new type SilcPrivateMessagePayload and defined an API
5077 for it in the lib/silcclient/silcprivate.[ch].
5079 * Tested private message private keys successfully. Tested the
5080 private message key set, unset and list commands with the new
5083 * Redefined the Channel Message Payload to include the channel
5084 message flags (equal with private message flags) to support
5085 for example CTCP style messages.
5087 * Defined some of the message (for channel and private message)
5088 flags. Updated the protocol specs and added the flags to the
5089 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5091 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added SilcKeyAgreementStatus type to the key agreement routines
5094 to indicate the current status and error if one occured.
5095 The status types are defined in the lib/silcclient/silcapi.h.
5097 * Added new local command KEY that is used to set and unset private
5098 keys for channels, set and unset private keys for private messages
5099 with remote clients and to send key agreement requests and
5100 negotiate the key agreement protocol with remote client. The
5101 key agreement is supported only to negotiate private message keys,
5102 it currently cannot be used to negotiate private keys for channels,
5103 as it is not convenient for that purpose.
5105 * Fixed a minor pending callback setting bug in the function
5106 silc_client_get_client_by_id_resolve, now the function works.
5107 Affected file lib/silcclient/idlist.c.
5109 * Added function silc_net_get_local_port to get local bound
5110 port by socket. Added to lib/silcutil/silcnet.[ch].
5112 * Added `sockets' and `sockets_count' fields to the SilcClient
5113 object. They hold the sockets of the listenning sockets in
5114 the client. Listenning sockets may be for example the key
5115 agreement server. Affected file lib/silcclient/client.[ch].
5116 Added functions the silc_client_add_socket and the
5117 silc_client_del_socket. They are exported to the application
5120 * Added ~./silc/clientkeys to support other client's public keys.
5122 * Renamed verify_server_key client operation to verify_public_key
5123 and added one argument to indicate the type of the connection
5124 (server, client etc.).
5126 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added silc_server_connection_auth_request to handle the
5129 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5130 silcd/packet_receive.[ch].
5132 * Added silc_server_send_connection_auth_request into the
5133 silcd/packet_send.c to send the connection auth request packet.
5135 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5138 * Fixed the public key authentication in responder side in the
5139 server. The `auth_data' pointer includes the SilcPublicKey
5140 not the path to the public key. Affected file silcd/protocol.c.
5142 * Implemented the public key authentication in the initiator side
5143 in the server. Affected file silcd/protocol.c.
5145 * Removed the [RedirectClient] config section from the server
5146 configuration. Is not needed and I don't want to implement it.
5148 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Cleaned up the CMODE command in the server. It now works
5151 correctly and supports all the modes defined in the protocol.
5152 Affected file is silcd/command.c.
5154 * Added `hmac_name' field to the SilcChannelEntry in the server
5155 to hold the default HMAC of the channel. It can be set when
5156 creating the channel (with JOIN command). Affected files
5159 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5160 type to indicate the change of the current cipher and hmac
5161 on the channel. Client can safely ignore the <cipher> argument
5162 (if it chooses to do so) since the CHANNEL_KEY packet will
5163 force the channel key change anyway. The <hmac> argument is
5164 important since the client is responsible of setting the new
5165 HMAC and the hmac key into use.
5167 * Fixed the CMODE command in the client library as well.
5169 * Tested CMODE command in router environment successfully.
5171 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Show the version of the remote client (or server) when connecting
5174 to the server. It is logged to the log file. Affected file
5175 is silcd/protocol.c.
5177 * Fixed the KILLED notify handling in the client library. The
5178 client must be removed from all channels when receiving the
5181 Also, do not remove the client entry when giving the KILL
5182 command but when the KILLED notify is received.
5184 * Removed silc_idlist_find_client_by_nickname from the server.
5185 Not needed anymore. Affected files silcd/idlist.[ch].
5187 * Implemented the CHANNEL_CHANGE notify type handling to the
5188 server. Affected file silcd/server.c.
5192 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5194 * Added silc_server_send_notify_invite to send the INVITE
5195 notify between routers.
5197 * Implemented the INVITE command correctly to the server.
5199 * Implemented the INVITE notify type handling in the server.
5201 * Implemented the INVITE command to the client library and on the
5204 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Added function silc_server_get_client_resolve to find the
5207 client entry by ID from all ID lists and then resolve it
5208 (using WHOIS) if it cannot be found. Affected file is
5211 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Implemented the BAN command to the client library.
5215 * The JOIN command in the server now checks the invite list
5218 * Changed the silc_command_reply_payload_encode_va and the
5219 silc_command_payload_encode_va to support that if argument is
5220 NULL it ignores and checks the next argument. Affected file
5221 lib/silccore/silccommand.c.
5223 * Added silc_server_send_notify_ban to send the BAN notify
5224 type between routers.
5226 * Chaned the silc_notify_payload_encode to support that if
5227 argument is NULL it ignores and checks the next argument.
5228 Affected file lib/silccore/silcnotify.c.
5230 * Tested ban lists in router environment successfully.
5232 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Implemented BAN command to the server, in silcd/command.[ch].
5236 * Removed the BAN and INVITE_LIST modes from the CMODE command
5239 * Added function silc_string_match to regex match two strings.
5240 Affected files lib/silcutil/silcutil.[ch].
5242 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Redefined parts of the SilcChannelEntry in the server to support
5245 the new ban and invite lists.
5247 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Redefined the INVITE command. The same command can be used to
5250 invite individuals to the channel but also to manage the invite
5251 list of the channel (to add to and remove from the invite list).
5252 Updated the protocol specs.
5254 * Added new command SILC_COMMAND_BAN that can be used to manage
5255 the ban list of the channel. Updated the protocol specs.
5257 * Removed the channel modes: the SILC_CMODE_BAN and the
5258 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5259 in the CMODE command. The equivalent features are now available
5260 using INVITE and BAN commands. Updated the protocol specs.
5262 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5263 in the network about change in the current ban list. The notify
5264 type is not used by the client.
5266 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5267 support the invite lists.
5269 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added new function silc_string_regexify that converts string
5272 including wildcard characters into regex string that can
5273 be used by the GNU regex library. Added into the file
5274 lib/silcutil/silcutil.[ch].
5276 Added silc_string_regex_combine to combine to regex strings
5277 into one so that they can be used as one regex string by
5278 the GNU regex library. Added into the file
5279 lib/silcutil/silcutil.[ch].
5281 Added silc_string_regex_match to match two strings. It returns
5282 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5284 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Imported GNU regex to the soruce tree into lib/contrib.
5287 Fixed some compiler warning from the regex.c.
5289 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Fixed MOTD command in the server to work in router environment.
5293 * Fixed the MOTD command in the client library to support
5294 the server argument in the command.
5296 * Added `nickname_len' argument to the silc_idlist_add_client
5297 in the server, as the `nickname' argument may be binary data
5300 * Added silc_idlist_get_channels to return all channels from
5303 * Implemented LIST command to the server. Affected file is
5306 * Implemented the LIST command to the client library and on the
5309 * Added [<user count>] argument to the LIST command reply.
5310 With private channels the user count is not shown.
5312 * Updated TODO and README.
5314 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * The client entry's data.registered must be TRUE even with
5317 global client entry on global client list. The data.registered
5318 is used to check whether the client is anymore in the network,
5319 for example with WHOWAS command so it must be valid.
5321 * Fixed the WHOWAS command in the server. It now actually works
5322 in router environment. Added function into silcd/command_reply.c
5323 silc_server_command_reply_whowas_save.
5325 * Added silc_idlist_purge function to the silcd/idlist.c
5326 to periodically purge the ID Cache.
5328 * Fixed INFO command in the server. It works now in router
5329 environment. Added <server name> argument to the INFO command
5330 reply. Updated the protocol specs.
5332 * Fixed minor bug in silc_idcache_purge to not purge if the
5333 expire value is zero.
5335 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5336 they were buggy because of the WHOWAS information.
5338 * Fixed local command MSG to handle the async resolving of
5339 the remote client properly. It used to fail the first MSG.
5340 Affected file silc/local_command.c.
5342 * Added `data_len' field to SilcIDCache context.
5344 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Update TODO. Todo in commands in the server.
5348 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5351 used by routers as broadcast packet to inform other routers
5352 about the changed user mode.
5354 Implemented the notify handling in the server. Affected file is
5355 silcd/packet_receive.c. Added the function
5356 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5358 * Added new generic Channel Payload and deprecated the New Channel
5359 Payload. The New Channel Payload is now the generic Channel
5362 * Added new argument `mode' to the silc_server_send_new_channel
5363 as it is required in the Channel Payload now.
5365 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5366 and created a new and real SilChannelPayload to represent the
5367 new generic Channel Payload. Implemented the encode/decode
5368 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5370 * Added silc_server_get_client_channel_list to return the list
5371 of channels the client has joined for WHOIS command reply.
5372 Affected file silcd/server.[ch].
5374 * Implemented the channel list sending in the WHOIS command reply
5375 in server and in the client.
5377 Implemented the channel list displaying on the user interface
5378 as well. Affected file silc/client_ops.c.
5380 * Added silc_channel_payload_parse_list to parse list of Channel
5381 Payloads. It returns SilcDList list of SilcChannelPayloads.
5382 Client for example can use this function to parse the list of
5383 channels it receives in the WHOIS command reply. The caller
5384 must free the list by calling silc_channel_payload_list_free.
5385 Affected files lib/silccore/silcchannel.[ch].
5387 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Added one new argument <user mode> to the WHOIS command reply
5390 to return the mode of the user in SILC. Updated the protocol
5393 Implemented it to the server and client.
5395 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Fixed the mode printing on the user interface on joining.
5398 Affected file silc/client_ops.c.
5400 * Implemented the UMODE command and user modes in general to the
5401 client library and to the user interface.
5403 * Implemented the UMODE command to the server.
5405 * The server now sends UNKNOWN_COMMAND error status if client sends
5406 unknown command. Affected file silcd/command.c.
5408 * All server commands now handle the command identifier the right
5409 way when sending the command reply to the client. The client can
5410 use to identify the command replies with the identifier.
5412 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Added silc_server_get_client_route to resolve the route to
5415 the client indicated by the client ID. Affected file is
5418 * Added silc_server_relay_packet as general function to relay
5419 packet to arbitrary destination. This deprecates functions
5420 like _send_private_message_key, _relay_notify etc. Affected
5421 file is silcd/packet_send.[ch].
5423 Removed silc_server_send_key_agreement,
5424 silc_server_send_private_message_key and
5425 silc_server_packet_relay_notify functions from the file
5426 silcd/packet_send.[ch].
5430 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5431 server. Affected file silcd/packet_receive.[ch].
5433 * Implemented the KILL command to the client. Implemented the
5434 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5435 Affected files lib/silcclient/command[_reply].c and
5436 lib/silcclient/client_notify.c. Implemented the KILL notify
5437 printing in the user inteface.
5439 * Fixed a lot silc_parse_nick memory leaks from the client
5440 library in the file lib/silcclient/command.c.
5442 * Changed the silc_server_send_notify_on_channels's `sender'
5443 argument from SilcSocketConnection to SilcClientEntry to
5444 check the sender as entry and not as connection object and not
5445 to send to the client provided as argument. The affected file
5446 is silcd/packet_send.[ch].
5448 * The notify packets that are destined directly to the client used
5449 to not to be processed by the server. Now changed that and the
5450 server processes all notify packets. After relaying the packet
5451 to the client the notify packet is processed in the server.
5453 * The silc_server_free_client_data now checks whether there is
5454 pending outgoing traffic for the client and purges the data to
5455 the network before removing the client entry.
5457 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5460 an client is killed from the SILC Network. Updated the protocol
5463 Added new function silc_server_send_notify_killed to the
5464 silcd/packet_send.[ch].
5466 * Added function silc_server_packet_relay_notify to relay notify
5467 packets that are destined directly to a client. In this case
5468 the server does not process the notify packets but merely relays
5469 it to the client. Affected file silcd/packet_send.[ch].
5471 Added also silc_server_packet_process_relay_notify to check
5472 whereto relay the notify. Affected file is
5473 silcd/packet_receive.[ch].
5475 * Implemented the KILL command to the server.
5479 * Added the backup schema desgined last fall to the protocol
5480 specs for everyone to see. The specification is in the
5481 *-spec-xx.txt draft and the packet type definitions for the
5482 backup routers is in *-pp-xx.txt draft. Thusly, added also
5483 new packet type SILC_PACKET_CELL_ROUTERS.
5485 * A big security problem in the implementation discovered. The
5486 signoff of an client did not cause new channel key generation
5487 which it of course should've done. The channel keys must be
5488 always re-generated when client leaves (or signoffs) the channel.
5489 The silc_server_remove_from_channels funtion now handles
5490 the channel key re-generation.
5492 * Added `sender' argument to the silc_server_send_notify_on_channels
5493 to not to send the client provided as argument. Affected file
5494 silcd/packet_send.[ch].
5496 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Implemented OPER and SILCOPER commands into the server and
5501 * Added silc_auth_verify and silc_auth_verify_data to verify
5502 the authentication directly from the authentication payload.
5503 It supports verifying both passphrase and public key based
5504 authentication. Affected file lib/silccore/silcauth.[ch].
5506 * Added `hash' field to the SilcIDListData structure. It is the
5507 hash negotiated in the SKE protocol. Affected file is
5510 * Slight redesigning of the SilcAuthPayload handling routines.
5511 Do not send SilcPKCS but SilcPublicKey as argument.
5513 * Implemented the public key authentication support to the
5514 serverconfig. The public key is loaded from the provided path
5515 and saved as authentication data to void * pointer. Thus,
5516 changed the unsigned char *auth_data to void *auth_data;
5518 * Fixed SHUTDOWN command to send the reply before the server
5519 is shutdown. :) Affected file silcd/command.c.
5521 * Fixed fatal bug in CONNECT command. The hostname was invalid
5522 memory and server crashed. Affected file silcd/command.c.
5524 * Fixed fatal bug in CLOSE command. The server_entry became
5525 invalid but was referenced later in the command. Affected file
5528 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Fixed fatal bug in failure packet handling. Server ignored
5531 the failure and thus crashed when it came.
5535 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5538 that the command may be executed only once in (about) 2 seconds.
5539 The old SILC_CF_LAG flag is same but allows command bursts up
5540 to five before limiting.
5542 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5543 server code. Various commands now includes the CF_LAG_STRICT
5544 flag to disallow any kind of miss-use of the command.
5546 * Fixed the silc_buffer_unformat to not to allocate any data
5547 if the length of the data is zero. It used to allocate the
5548 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5550 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Changed the format of AdminConnection configuration section
5553 in the server. Added username of the admin to the format.
5554 Affected files silcd/serverconfig.[ch].
5556 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5557 to return admin configuration data by host, username and/or
5560 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Implemented WHOWAS command to the server. Added the functions:
5564 silc_server_command_whowas_parse,
5565 silc_server_command_whowas_send_reply,
5566 silc_server_command_whowas_from_client and
5567 silc_server_command_whowas_from_server
5569 * Added <Client ID> argument to the WHOWAS command reply. Updated
5570 the protocol specs accordingly.
5572 * Implemented WHOWAS command and command_reply to the client
5575 Implemented the WHOWAS printing on the user interface.
5577 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Added new argument to the WHOWAS command reply, the real name.
5580 It is an optional argument. Updated the protocol specs.
5582 * Added SilcIDCacheDestructor callback that is registered when
5583 the SilcIDCache is allocated. The callback is called when
5584 an cache entry in the ID Cache expires, or is purged from the
5585 cache. Added into lib/silccore/idcache.[ch].
5587 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5588 to destruct the client entries when the cache entry expires.
5589 Other ID Cache's in server and in the client library ignores
5592 * If the ID Cache entry's `expire' field is zero then the entry
5593 never expires. Added boolean `expire' argument to the
5594 silc_idcache_add function in the lib/silccore/idcache.[ch].
5595 If it is TRUE the default expiry value is used.
5597 * Added silc_server_free_client_data_timeout that is registered
5598 when client disconnects. By default for 5 minutes we preserve
5599 the client entry for history - for WHOWAS command.
5601 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Added support to the server to enforce that commands are not
5604 executed more than once in 2 seconds. If server receives
5605 commands from client more frequently, timeout is registered
5606 to process the commands. Affected file silcd/command.c.
5607 Added new function silc_server_command_process_timeout.
5609 * Changed NICK_NOTIFY handling in client library to check that
5610 if the client's nickname was changed, so there is no need to
5611 resolve anything from the server.
5613 * Removed error printing from the WHOIS and IDENTIFY commands.
5614 If error occurs then it is ignored silently in the client library.
5615 The application, however, may map the received error to
5616 human readable error string. The application currently maps
5617 the NO_SUCH_NICKNAME error to string.
5619 * Made the command status message public to the application. Moved
5620 them from lib/silcclient/command_reply.c to
5621 lib/silcclient/command_reply.h. The application can map the
5622 received command status to the string with the
5623 silc_client_command_status_message function.
5625 * Added check to the server to check that client's ID is same
5626 as the Source ID in the packet the client sent. They must
5629 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Added dist-bzip hook to the Makefile.am to make bzip2
5632 compressed distributions.
5634 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Server now enforces the maximum length for the nickname and
5637 the channel as protocol specification dictates. 128 bytes for
5638 nickname and 256 bytes for channel name.
5640 * Moved the WHOIS printing to the application. The client libary
5641 does not print out the WHOIS information anymore, the application
5642 must do it. Renamed silc_client_command_reply_whois_print to
5643 the silc_client_command_reply_whois_save.
5645 The client's idle time is also sent to the application now, and
5646 the idle is shown on screen.
5648 * Added silc_client_command_reply_identify_save to save the
5649 received IDENTIFY entries.
5651 * Do not check for channel private keys in message sending and
5652 reception if the channel does not have the PRIVKEY mode set.
5653 Affected file lib/silclient/client_channel.c.
5655 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5658 just surfaced after chaning the JOIN procedure.
5660 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Added silc_client_get_clients_by_list to get client entries
5663 from Client ID list, that is returned for example by JOIN
5664 and USERS command replies. The application should use this
5665 function for example when JOIN command reply is received to
5666 resolve the clients already on the channel (library does not
5667 do that anymore as USERS command reply is not used in the JOIN
5668 procedure anymore). Affected files lib/silcclient/silcapi.h and
5669 lib/silcclient/idlist.c.
5671 * JOIN command reply and USERS command reply returns now SilcBuffer
5672 pointers instead of unsigned char pointers when returning
5673 the client list and mode list.
5675 * Added <Client ID> argument to the JOIN command reply, mainly
5676 for the server to identify for which client the command was
5677 originally sent. Updated protocol specs accordingly.
5679 * Added SilcDlist private_key pointer to the SilcChannelEntry
5680 in the client to support the channel private keys. Affected
5681 file is lib/silcclient/idlist.h.
5683 * Added SilcChannelPrivateKey argument to the function
5684 silc_client_send_channel_message so that application can choose
5685 to use specific private ke if it wants to. If it is not provided,
5686 the normal channel key is used, unless private keys are set.
5687 In this case the first (key that was added first) is used
5688 as the encryption key.
5690 * Implemented the support for channel private key handling.
5691 Implemented the following functions:
5693 silc_client_add_channel_private_key,
5694 silc_client_del_channel_private_keys,
5695 silc_client_del_channel_private_key,
5696 silc_client_list_channel_private_keys and
5697 silc_client_free_channel_private_keys
5699 Affected file lib/silcclient/client_channel.c.
5701 * Added the support for the private keys in the channel message
5702 sending and encryption and in the message reception and
5703 decryption. Affected funtions are
5704 silc_client_send_channel_message and silc_client_channel_message.
5706 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added SKE's key verify callback to the client library's
5709 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5711 * Removed the statement that server (or router) must send USERS
5712 command reply when joining to the channel so that the client
5713 knows who are on the channel. Instead, the client list and
5714 client's mode list is now sent in the JOIN command reply to the
5715 client who joined channel. This is better solution.
5717 * Added function silc_server_get_users_on_channel and function
5718 silc_server_save_users_on_channel to the silcd/server.[ch].
5720 * Removed function silc_server_command_send_users from the
5723 * Do not show topic on the client library anymore. The topic is
5724 sent in the command reply notify to the application and the
5725 application must show the topic now.
5727 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Added client searching by nickname hash into the IDENTIFY and
5730 WHOIS commands in the server as they were clearly missing from
5731 them. Affected file is silcd/command.c.
5733 * Fixed a bug in private message receiving in the client library.
5734 The remote ID was freed and it wasn't supposed, now it is
5737 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Minor fix to the channel payload; allocate the data area, as it
5740 needs to be of specific length.
5742 * If the key agreement port is zero then the operating
5743 system will define the bound port. Affected files are
5744 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5746 * Added new function silc_channel_payload_decrypt into the file
5747 lib/silccore/silcchannel.[ch].
5749 * Moved the channel message etc, check from silc_packet_decrypt
5750 to applications. The library calls now a generic
5751 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5752 when the packet is either normal or special. This was done to
5753 allow more wide range of checking that was not allowed when
5754 the code was in library. Now applications can do virtually any
5755 checks to the packet and return to the library the decision how
5756 the packet should be processed. Affected files are
5757 lib/silccore/silcpacket.[ch].
5759 Added silc_server_packet_decrypt_check to the server and
5760 silc_client_packet_decrypt_check to the client library.
5762 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5763 to send with specified source and destination information.
5765 * Channel message delivery between routers was broken after the
5766 channel key distribution was fixed earlier. The channel key
5767 was used be to distributed to other routers as well which is not
5768 allowed by the protocol. Now this is fixed and channel keys
5769 really are cell specific and the channel message delivery between
5770 routers comply with the protocol specification.
5772 * Fixed various commands in server to check also the global list
5773 for the channel entry and not just the local list. The affected
5774 file silcd/command.c.
5776 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Added assert()s to buffer formatting and unformatting routines
5779 to assert (if --enable-debug) when error occurs. Affected
5780 file: lib/silcutil/silcbuffmt.c.
5782 * Changed to auto-reconnect to check whether the remote host is
5783 router and register the re-connect timeout if it is. It used
5784 to check that whether we are normal server, but router must do
5785 auto-reconnect with another router as well. Affected file
5788 * Removed the [<key len>] option from CMODE command as the cipher
5789 name decides the key length, nowadays. See the defined ciphers
5790 from the protocol specification.
5792 * Added [<hmac>] option to the CMODE command to define the HMAC
5793 for the channel. Added SILC_CMODE_HMAC channel mode.
5795 * Added [<hmac>] option for the JOIN command so that user can
5796 select which HMAC is used to compute the MACs of the channel
5799 * Added Hmac field to the Channel Message Payload. The integrity
5800 of plaintext channel messages are now protected by computing
5801 MAC of the message and attaching the MAC to the payload. The
5802 MAC is encrypted. Now, it is clear that this causes some
5803 overhead to the size of the packet but rationale for this is that
5804 now the receiver can verify whether the channel message decrypted
5805 correctly and also when private keys are set for the channel the
5806 receiver can decrypt the packet with several keys and check from
5807 the MAC which key decrypted the message correctly.
5809 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5810 lib/silccrypt/silccipher.[ch].
5812 * Added silc_hash_len to return the digest length into the
5813 lib/silcrypt/silchash.[ch].
5815 * Rewrote parts of Silc Channel Payload interface in the
5816 lib/silccore/silcchannel.[ch]. The encode function now also
5817 encrypts the packet and parse function decrypts it.
5819 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Fixed a minor formatting bug in the SKE's key material processing.
5822 It actually might have processed the keys wrong way resulting
5825 * Redefined the mandatory HMAC algorithms and added new algorithms.
5826 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5827 and hmac-md5 truncated to 96 bits. The mandatory is now
5828 hmac-sha1-96. Rest are optional (including the one that used
5829 to be mandatory). Rationale for this is that the truncated HMAC
5830 length is sufficient from security point of view and can actually
5831 make the attack against the HMAC harder. Also, the truncated
5832 HMAC causes less overhead to the packets. See the RFC2104 for
5835 * Added new [hmac] configuration section. The SKE used to use
5836 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5837 is of course wrong. The official names that must be proposed in
5838 the SKE are the ones defined in the protocol specification
5839 (hmac-sha1-96 for example). The user can configure any hmac
5840 using any hash function configured in the [hash] section. At
5841 least, the mandatory must be configured.
5843 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5845 * Added HMAC list to the SKE proposal list. It has now both
5846 hash algorithm list and HMAC list. This makes the protocol
5847 incompatible with previous versions. The SKE now seems to work
5848 the way it is supposed to work, for the first time actually.
5850 * Defined plain Hash algorithms to the protocol specification.
5853 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Implemented support for key agreement packets into the server.
5856 Added functions silc_server_key_agreement and
5857 silc_server_send_key_agreement. Other than these functions,
5858 server has nothing to do with this packet.
5860 * Added support for private message key packets into the server.
5861 Added functions silc_server_private_message_key and
5862 silc_server_send_private_message_key.
5866 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5867 called in the protocol's final callback instead in the END
5868 protocol state. This makes a little more sense and in the same
5869 time in client we can use the same protocol routines for normal
5870 key exchange and to key agreement packet handling as well.
5872 * Added to both client's and server's KE protocol context the
5873 SilcSKEKeyMaterial pointer to save the key material. We will
5874 bring the key material to the protocol's final callback by doing
5875 this. The final callback must free the key material.
5877 * Added SKE's packet_send callback into client's KE protocol
5878 context so that the caller can choose what packet sending function
5879 is used. This way we can use different packet sending when
5880 doing normal SKE when doing key agreement packet handling (in
5881 the key agreement packet handling we do not want to encrypt
5884 * Implemented the responder side of the key agreement routines
5885 in the client. The client can now bind to specified port and
5886 accept incoming key negotiation. The key material is passed
5887 to the application after the protocol is over.
5889 * Implemented the processing of incoming Key Agreement packet
5890 in the client. Added function silc_client_key_agreement to
5893 * Implemented the intiator side of the key agreement routines
5894 in the client. The client can now initiate key agreement with
5895 another remote client. The key material is passed to the
5896 application after the protocol is over.
5898 * Created client_keyagr.c to include all the key agreement
5901 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5902 SILC_TASK_CALLBACK except that it is not static.
5904 * Created client_notify.c and moved the Notify packet handling
5905 from the client.[ch] into that file.
5907 * Created client_prvmsg.c and moved all private message and
5908 private message key routines from the client.[ch] into that file.
5910 * Create client_channel.c and moved all channel message and
5911 channel private key routines from the client.[ch] into that file.
5913 * Changed silc_client_get_client_by_id_resolve to resolve with
5914 WHOIS command instead of IDENTIFY command, in the file
5915 lib/silclient/idlist.c.
5917 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Implemented the SKE's responder side to the Client library.
5921 * When FAILURE is received to the protocol do not trust it
5922 blindly. Register a timeout to wait whether the remote closes
5923 the connection as it should do it, only after that process the
5924 actual failure. This was changed to both client and server.
5926 * Added client_internal.h to include some of the structures
5927 there instead of client.h in lib/silcclient/.
5929 * Added function silc_task_unregister_by_callback to unregister
5930 timeouts by the callback function.
5932 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Some "Incomplete WHOIS info" errors has been appearing on the
5935 log files. Took away the entry->userinfo check from WHOIS
5936 reply sending. The entry->userinfo is now " " if client did not
5937 provide one. I thought this was fixed earlier but something
5938 is wrong still. Let's see if the error still appears.
5940 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Fixed a minor bug in the login when the channel key is
5943 re-generated in the server. It used to generate the key in
5944 wrong order and thus caused problems in the channel traffic.
5946 * Fixed a minor bug in channel key distsribution after
5947 KICK command. The key was not sent to the router even though
5950 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Added silc_ske_process_key_material_data as generic routine
5953 to process any key material as the SILC protocol dictates. The
5954 function is used by the actual SKE library but can be used by
5955 applications as well. This relates to the private message keys
5956 and the channel private keys since they must be processed the
5957 same way the normal SILC session keys. The protocol dictates
5958 this. Affected files: lib/silcske/silcske.[ch].
5960 Added also silc_ske_free_key_material to free the
5961 SilcSKEKeyMaterial structure.
5963 * Defined silc_cipher_set_key function to set the key for
5964 cipher without using the object's method function. The affected
5965 files: lib/silccrypt/silccipher.[ch].
5967 * Implemented silc silc_client_add_private_message_key,
5968 silc_client_add_private_message_key_ske,
5969 silc_client_del_private_message_key,
5970 silc_client_list_private_message_keys and
5971 silc_client_free_private_message_keys functions in the
5974 Added functions silc_client_send_private_message_key to send
5975 the Private Message Key payload and silc_client_private_message_key
5976 to handle incoming Private Message Key payload.
5978 * Added Cipher field to the Private Message Key payload to set
5979 the cipher to be used. If ignored, the default cipher defined
5980 in the SILC protocol (aes-256-cbc) is used.
5982 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Removed lib/silcclient/ops.h file.
5986 Redefined parts of the SILC Client Library API. Created new
5987 file silcapi.h that deprecates the ops.h file and defines the
5988 published Client Library API. Defined also private message key
5989 API and channel private key API into the file.
5991 This is the file that the application must include from the
5992 SILC Client Library. Other files need not be included by
5993 the application anymore.
5995 * Added new key_agreement client operation callback and also
5996 defined the Key Agreement library API for the application.
5998 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6001 is used by clients to request key negotiation between another
6002 client in the SILC network. If the negotiation is started it
6003 is performed using the SKE protocol. The result of the
6004 negotiation, the secret key material, can be used for example
6005 as private message key.
6007 Implemented the Key Agreement payload into the files
6008 lib/silccore/silauth.[ch].
6010 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6012 * Redefined ciphers for the SILC protocol. Added some new ciphers
6013 and defined the key lengths for the algorithms. Changed the
6014 code accordingly. The default key length is now 256 bits.
6016 * Fixed SKE key distribution function silc_ske_process_key_material
6017 when the key length is more than 128 bits. The default key
6018 length in SILC is now 256 bits.
6020 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6021 to indicate unsupported algorithm.
6023 * Renamed rijndael.c to aes.c and all functions as well.
6025 * Fixed a long standing channel key setting bug in client library.
6026 Weird that it has never surfaced before.
6028 * Fixed bug in channel deletion. If the entire channel is removed
6029 then it must also delete the references of the channel entry
6030 from the client's channel list as the client's channel entry and
6031 the channel's client entry share same memory.
6033 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Implemented CONNECT and SHUTDOWN commands in the client.
6037 * Implemented CLOSE command to the client.
6039 * Added the function silc_idlist_find_server_by_name into the
6040 files silcd/idlist.[ch].
6042 Added the function silc_idlist_find_server_by_conn into the
6043 files silcd/idlist.[ch].
6045 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * DIE command was renamed to SHUTDOWN. Updated the both code
6050 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6051 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6053 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6056 * Added function silc_server_create_connection function to create
6057 connection to remote router. My server implementation actually
6058 does not allow router to connect to normal server (it expects
6059 that normal server always initiates the connection to the router)
6060 so the CONNECT command is only good for connecting to another
6063 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6066 or some other client was kicked from the channel.
6068 Implemented the handling of the notify type to both client
6071 Implemented silc_server_send_notify_kicked to send the KICKED
6072 notify. It is used to send it to the server's primary router.
6074 * Implemented the KICK command into server and client.
6076 * Added `query' argument to the silc_idlist_get_client function
6077 to indicate whether to query the client from server or not if
6080 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6081 to indicate that the client is not channel founder.
6085 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Removed the rng context from SilcPacketContext structure and
6088 changed that the packet routine uses the Global RNG API.
6090 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6092 * Added support for quit message that client can "leave" on the
6093 channel when it quits the SILC. It is ditributed inside the
6094 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6096 Added silc_server_free_client_data that will take the
6097 signoff message as argument.
6099 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6101 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Updated parts of the protocol specification to keep it up
6106 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6108 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6109 payloads in one packet.
6111 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6112 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6113 use now the new List flag.
6115 * Also deprecated the following packet types: REPLACE_ID,
6116 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6118 * Added list support for Notify packet in server.
6120 * Added silc_server_send_notify_channel_change to send the
6121 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6122 the silc_server_send_replace_id.
6124 * Added silc_server_send_notify_nick_change to send the
6125 NICK_CHANGE notify type. Deprecates the function
6126 silc_server_send_replace_id.
6128 * Added silc_server_send_notify_join to send the JOIN notify type.
6129 Deprecates the function silc_server_send_new_channel_user.
6131 * Added silc_server_send_notify_leave to send LEAVE notify type.
6132 Deprecates the function silc_server_send_remove_channel_user.
6134 * Added silc_server_send_notify_cmode and
6135 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6136 types. Deprecates the silc_server_send_set_mode function.
6138 * Added SERVER_SIGNOFF notify type to indicate that server has
6139 quit. This means that all clients on the channel from that
6140 server will drop. This can be also used when netsplit happens.
6142 Deprecated REMOVE_ID packet type since it is not needed anymore
6145 Added silc_server_send_notify_server_signoff to send the
6146 SERVER_SIGNOFF notify type. Deprecates the function
6147 silc_server_send_remove_id.
6149 Added also silc_server_send_notify_signoff to send the
6150 SIGNOFF notify type.
6152 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6153 SILC protocol from this day on. Changed the protocol
6154 specification as well.
6156 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6157 notify type. It is used between routers to notify about
6158 topic changes on a channel.
6160 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6163 * Partly updated the protocol specification to comply with the
6164 changes now made. It is still though a bit outdated.
6166 * The JOIN notify type now takes one extra argument <Channel ID>.
6167 The packet used to be destined to the channel but now the
6168 JOIN type may be sent as list thus it is impossible to
6169 destine it to any specific channel. By adding this argument
6170 it is again possible.
6172 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Added CREDITS file. The CHANGES and CREDITS file will appear
6175 in the distribution as well.
6177 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6180 types in the server's silcd/packet_receive.c.
6182 * Implemented CMODE and CUMODE to work in router environment.
6184 * Fixed minor encoding and decoding buglet from the
6185 lib/silccore/silcmode.c.
6187 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6190 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6192 * Changed all SilcConfigServer* and silc_config_server* to
6193 SilcServerConfig* and silc_server_config*, respectively.
6196 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Associated the ID (client or server ID) to the Authentication
6199 Payload to avoid any possibility of forging. Updated the
6200 protocol specification and the code accordingly.
6202 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * The RSA key length is now save to the RsaKey context in the
6205 key generation process in lib/silccrypt/rsa.c. The key length
6206 is now used to figure out the maximum size of the block allowed
6207 to be encrypted/signed.
6209 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6210 is equivalent to the silc_mp_mp2bin but does not allocate any
6213 * Changed silc_mp_mp2bin API to take length argument. If it is
6214 non-zero then the buffer is allocated that large. If zero, then
6215 the size is approximated using silc_mp_sizeinbase, which however
6218 * Created Global RNG API which is global RNG that application can
6219 initialize. After initializing, any routine anywhere in the
6220 code (including library) can use RNG without allocating a new
6221 RNG object. This was done to allow this sort of use of the
6222 RNG in code that has no chance to allocate RNG object. All
6223 applications currently allocate this and many routines in the
6224 library use this. Affected file lib/silccrypt/silcrng.[ch].
6226 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6227 it to use the Global RNG API.
6229 * Defined Authentication Payload into protocol specification that
6230 is used during SILC session to authenticate entities. It is
6231 used for example by client to authenticate itself to the server
6232 to obtain server operator privileges.
6234 Implemented this payload into the lib/silccore/silcauth.[ch].
6235 Implemented also routines for public key based authentication
6236 as the new protocol specification dictates.
6238 Moved definitions of different authentication methods from
6239 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6241 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6242 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6243 silc_pkcs_verify_with_hash functions into the file
6244 lib/silccrypt/silcpkcs.[ch].
6246 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * The client entry's userinfo pointer must be always valid.
6249 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6250 will fail since it requires the userinfo. Now, the userinfo
6251 is allocated as "" if actual userinfo does not exist. Actually,
6252 it must exist and it is totally Ok to drop client connections
6253 that does not announce the userinfo. However, we will make
6254 this workaround for now.
6256 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6257 to return the remote port by socket.
6259 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6262 SILC_SERVER_PENDING_EXEC and added an new macro
6263 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6264 data or when error occurs while processing the pending command.
6266 Added new argument `destructor' into silc_server_command_pending
6267 and to the SilcServerCommandPending object. This destructor is
6268 now called after calling the pending callback or if error occurs
6269 immediately. If error occurs the actual pending callback won't
6270 be called at all - only the destructor. The destructor may be
6271 NULL if destructor is not needed.
6273 All this applies for client library code as well. Similar
6274 changes were made there as well for the pending commands.
6276 In the client, the application must now allocate the
6277 SilcClientCommandContext with the silc_client_command_alloc
6280 * Added reference counter to the SilcServerCommandContext. Added
6281 function silc_server_command_alloc and silc_server_command_dup
6284 Same type of functions added to the client library for the same
6287 * Removed the cmd_ident from IDListData away since it is now
6288 global for all connections. It is the command identifier used
6289 in command sending and with pending commands. The affected file
6292 * Added reference counter to the SilcSocketConnection objecet to
6293 indicate the usage count of the object. The object won't be
6294 freed untill the reference counter hits zero. Currently only
6295 server uses this, and client ignores it. The client must be
6296 set to use this too later. The affected files are
6297 lib/silccore/silcsockconn.[ch]. Added also the function
6298 silc_socket_dup to increase the reference counter.
6300 This was mainly added because it is possible that the socket
6301 is removed underneath of pending command or other async
6302 operation. Now it won't be free'd and proper DISCONNECTING
6303 flags, etc. can be set to avoid sending data to connection that
6304 is not valid anymore.
6306 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6307 the connection. After that it sets SILC_SET_DISCONNECTED.
6308 It is, however, possible that the socket data is not still freed.
6309 The silc_server_packet_process now checks that data is not
6310 read or written to connection that is DISCONNECTED. The socket
6311 get's freed when the reference counter hits zero.
6313 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Changed the client operation API: channel_message operation's
6316 `sender' is now the client entry of the sender, not the nickname
6317 and the `channel' is the channel entry, not the channel name.
6319 In the private_message operation the `sender' is now also the
6320 client entry of the sender not the nickname.
6322 Affected file is lib/silcclient/ops.h and all applications
6323 using the client operations.
6325 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Moved the calling of ops->connect() from connect_to_server_final
6328 into receive_new_id functin since that is the point when the
6329 client is actually allowed to send traffic to network. The
6330 affected file is lib/silcclient/client.c.
6332 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6335 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6336 (if needs broadcasting) instead of broadcasting the packets one
6337 by one which would make a burst in the network traffic.
6339 * Added `broadcast' argument to the functions in silcd/server.[ch]
6340 silc_server_create_new_channel[_with_id] to indicate whether
6341 to send New Channel packet to primary router.
6343 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Added new function into the silcd/server.[ch] files:
6346 silc_server_create_new_channel_with_id to create new channel with
6347 already existing Channel ID.
6349 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6350 lib/silccore/silcpacket.h. This packet is used t send list of
6351 Set Mode payloads inside one packet. Server uses this to set
6352 the modes for the channels and clients on those channels, that it
6353 announced to the router when it connected to it. The protocol
6354 specification has been updated accordingly.
6356 * The silc_server_new_channel did not handle the packet coming
6357 from normal server as it normally does not send that. However,
6358 when it announces its channels it does send it. Implemented
6359 the support for that.
6361 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6362 into the file lib/silccore/id.h.
6364 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Fixed memory leaks in the functions silc_idlist_del_client,
6367 silc_idlist_del_channel and silc_idlist_del_server in the file
6368 silcd/idlist.c. All of those leaked like a sieve.
6370 * Fixed some small memory leaks in the client's function
6371 silc_client_notify_by_server.
6373 * Added functions into silcd/server.c: silc_server_announce_clients,
6374 silc_server_announce_channels and silc_server_announce_server.
6375 These functions are used by normal and router server to announce
6376 to its primary router about clients, channels and servers (when
6377 router) that we own. This is done after we've connected to the
6380 These functions effectively implements the following packet types:
6381 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6382 and SILC_PACKET_NEW_ID_LIST.
6384 * Added new functions into the silcd/packet_receive.[ch]:
6385 silc_server_new_id_list, silc_server_new_channel_list and
6386 silc_server_new_channel_user_list to handle the incoming
6387 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6389 * Added support of changing Channel ID in the function
6390 silc_server_replace_id. If the server that announces a channel
6391 to the router already exists in the router (with same name but
6392 with different Channel ID), router is responsible to send
6393 Replace ID packet to the server and force the server to change
6394 the Channel ID to the one router has.
6396 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6397 client that the Channel ID has been changed by the router. The
6398 normal server sends this to the client. Client must start using
6399 the new Channel ID as the channel's ID.
6401 Implemented handling of this new type into lib/silcclient/client.c
6402 into the function silc_client_notify_by_server.
6404 * Added new function silc_idlist_replace_channel_id into the files
6405 silcd/idlist.[ch] to replace the Channel ID.
6407 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Call silc_server_command_identify_check always when processing
6410 the IDENTIFY command in silcd/command.c
6412 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6415 send keepalive packets. The packet can be sent by clients,
6416 servers and routers.
6418 Added function silc_socket_set_heartbeat into the file
6419 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6420 If not set, the heartbeat is not performed. The actual
6421 heartbeat is implemented in the low level socket connection
6422 library. However, application is responsible of actually
6425 Added silc_server_send_heartbeat to send the actual heartbeat
6426 packet into silcd/packet_send.[ch]. Server now performs
6427 keepalive with all connections.
6429 * Added silc_task_get_first function into lib/silcutil/silctask.c
6430 to return the timeout task with shortest timeout. There was a bug
6431 in task unregistration that caused problems. TODO has been
6432 updated to include that task system must be rewritten.
6434 * The client library will now resolve the client information when
6435 receiving JOIN notify from server for client that we know but
6436 have incomplete information.
6438 * Rewrote parts of silc_server_remove_from_channels and
6439 silc_server_remove_from_one_channel as they did not remove the
6440 channel in some circumstances even though they should've.
6442 * Encryption problem encountered in server:
6444 The LEAVE command used to send the Channel Key packet to the
6445 router immediately after generating it. However, the code
6446 had earlier sent Remove Channel user packet but not immediately,
6447 ie. it was put to queue. The order of packets in the router
6448 was that Channel Key packet was first and Remove Channel User
6449 packet was second, even though they were encrypted in the
6450 reverse order. For this reason, MAC check failed. Now, this
6451 is fixed by not sending the Channel Key packet immediately but
6452 putting it to queue. However, this is more fundamental problem:
6453 packets that are in queue should actually not be encrypted
6454 because packets that are sent immediately gets encrypted
6455 actually with wrong IV (and thus MAC check fails). So, packets
6456 that are in queue should be encrypted when they are sent to
6457 the wire and not when they put to the queue.
6459 However, the problem is that the current system has not been
6460 designed to work that way. Instead, the packet is encrypted
6461 as soon as possible and left to the queue. The queue is then
6462 just purged into wire. There won't be any fixes for this
6463 any time soon. So, the current semantic for packet sending
6466 o If you send packet to remote host and do not force the send
6467 (the packet will be in queue) then all subsequent packets to the
6468 same remote host must also be put to the queue. Only after the
6469 queue has been purged is it safe again to force the packet
6472 o If you send all packets immediately then it safe to send
6473 any of subsequent packets through the queue, however, after
6474 the first packet is put to queue then any subsequent packets
6475 must also be put to the queue.
6477 Follow these rules and everything works fine.
6479 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Added new function silc_server_remove_clients_by_server to
6482 remove all client entries from ID list when the server connection
6483 is lost. In this case it is also important to invalidate all
6484 client entires as they hold the invalid server entry. This
6485 fixes fatal bug when server has lost connection and will reconnect
6488 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Made some sanity checks to silc_server_daemonise like to check
6491 whether the requested user and group actually exists.
6493 * Added sanity check to SKE's silc_ske_responder_finish to check
6494 that the public and private key actually is valid.
6496 * Invalidate the client's nickname when receiving Replace ID
6497 packet and the Client ID is being replaced. This means that the
6498 server will query the nickname if someone needs it (client)
6501 * Sort the ID Cache in client library when the ID Cache data
6502 has changed (needs sorting).
6504 * Do not allow for SILC client to create several connections to
6505 several servers. The client does not support windows right now
6506 and generating multiple connections causes weird behaviour.
6508 Irssi-silc client does support windows and can handle several
6509 connections without problems, see: www.irssi.org and SILC plugin.
6511 * Fixed some places where client was added to the IDList. The
6512 rule of thumb is following (in order to get everything right):
6513 If the client is directly connected local client then the
6514 `connection' argument must be set and `router' argument must be
6515 NULL to silc_idlist_add_client function. If the client is not
6516 directly connected client then the `router' argument must
6517 bet set and the `connection' argument must be NULL to the
6518 silc_idlist_add_client function.
6520 * The funtion silc_server_packet_send_local_channel actually did
6521 not check whether the client was locally connected or not. It
6522 does that now. Fixed a bug related to LEAVE command.
6524 * Fixed Remove Channel User payload parsing bug in server's
6525 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6527 * The server's silc_server_save_channel_key now checks also the
6528 global ID list for the channel as it might not be in the local
6529 list. Fixed a bug related to LEAVE command.
6531 * Is this the end of the [<unknown>] buglet that has been lurking
6532 around for a long time? A little for loop fix in server's
6533 silc_server_command_whois_parse that is used by both IDENTIFY
6534 and WHOIS command. At least, this was a clear bug and a cause
6535 of one type of [<unknown>] buglet.
6537 * WHOIS and IDENTIFY commands call the function
6538 silc_server_command_[whois/identify]_check function even if
6539 we are not router server.
6541 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Added --with-gmp configuration option. If set the GMP
6544 is always compiled in the SILC source tree. If not set then
6545 it is checked whether the system has the GMP3 installed. If
6546 it has then the GMP won't be compiled (the system's headers
6547 and library is used), if it doesn't have it then the GMP is
6548 compiled in the SILC source tree.
6550 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Changed RSA private exponent generation to what PKCS #1
6553 suggests. We try to find the smallest possible d by doing
6554 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6555 not security fix but optimization.
6557 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Added new config entry [Identity] to fork the server and run
6560 it as specific user and group. A patch from Bostik.
6562 * Imported Dotconf configuration library into lib/dotconf.
6563 This will be used to create the SILC configuration files later.
6564 It will appear in the distsribution after this commit.
6566 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * A big code auditing weekend happening. Auditing code for
6569 obvious mistakes, bugs and errors. Also, removing any code
6572 Removed files for being obsolete:
6574 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6575 inline in the file lib/silcutil/silcbuffer.h)
6577 o lib/silcutil/silcbufutil.c (the header has inline versions)
6579 Changed code to fix possible error conditions:
6581 o The buffer formatting routines now check that the destination
6582 buffer really has enough space to add the data. This applies for
6583 both buffer formatting and unformatting
6584 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6585 unformatting was changed to accomodate following rules:
6586 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6587 sent to the function while XXX_*STRING will not allocate or copy
6588 the data into the buffer. Instead it sets the pointer from the
6589 buffer into the pointer sent as argument (XXX_*STRING used to
6590 require that the pointer must be allocated already). This change
6591 makes this whole thing a bit more consistent and more optimized
6592 (note that the data returned in the unformatting with XXX_*STRING
6593 must not be freed now). The routines return now -1 on error.
6595 o Tried to find all code that use buffer_format and buffer_unformat
6596 and added return value checking to prevent formatting and
6597 especially unformatting errors and possible subsequent fatal
6600 o Changed ske->x and ske->KEY to mallocated pointers in
6601 lib/silcske/silcske.h. Fixed possible data and memory leak.
6603 o Added return value checking to all *_parse* functions. Fixed
6604 many memory leaks as well.
6606 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6607 so that buffer overflows would not happen. All code now also
6608 checks the return value as it can fail.
6610 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Added reconnection support to server if the normal server looses
6613 its connection to the router (for example if router is rebooted).
6614 The server performs normal reconnection strategy implemented
6615 to the server. Affected file silcd/server.c.
6617 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Added new packet type SILC_PACKET_SET_MODE that is used to
6620 distribute the information about changed modes (for clients,
6621 channels and clients channel modes) to all routers in the
6622 network. Updated the protocol specification accordingly.
6624 Added functions into silcd/packet_send.c and
6625 silcd/packet_receive.c: silc_server_send_set_mode,
6626 silc_server_set_mode.
6628 Added new files silcmode.[ch] into lib/silccore that implements
6629 the encoding and decoding of Set Mode Payload. Added new type
6630 SilcSetModePayload. Moved the definitions of different modes
6631 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6633 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6635 * Oops, a little mistake in server's connection authentication
6636 protocol. The protocol is not ended with FAILURE but with
6637 SUCCESS if the authentication is Ok. :) Affected file is
6640 * Implemented NICK_CHANGE notify handling in server in the file
6641 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6642 the local clients on the channel. After the changing nickname
6643 in router environment snhould work and the [<unknown>] nickname
6644 should appear no more.
6646 The silc_server_replace_id function that receives the Replace ID
6647 payload now sends the NICK_CHANGE notify type also in the file
6648 silcd/packet_receive.c
6650 * Changed WHOIS and IDENTIFY command to support the maximum amount
6651 of arguments defined in protocol specs (3328 arguments). This
6652 fixed a bug that caused problems when there were more than three
6655 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6657 * Added extra parameter, command identifier, to the
6658 silc_client_send_command so that explicit command identifier
6661 Changed that ID list routines uses specific command identifier
6662 when sending WHOIS/IDENTIFY requests to the server so that they
6663 can be identified when the reply comes back.
6665 Affected files lib/silcclient/command.[ch],
6666 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6668 * Added `sender' argument to silc_server_packet_send_to_channel
6669 to indicaet the sender who originally sent the packet to us
6670 that we are now re-sending. Ignored if NULL. Affected file
6671 silcd/packet_send.[ch].
6673 * Added some server statistics support in silcd/server_internal.h
6674 SilcServerStatistics structure and around the server code. Also
6675 send some nice statistics information when client is connecting
6678 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed channel ID decoding in server's JOIN command reply in
6681 silcd/command_reply.c
6683 * Fixed braodcasting of replace ID payload to not to send it if
6684 we are standalone server in silcd/packet_receive.c.
6686 * Fixed all channel message sending routines to not to send
6687 packets to clients that has router set, since they are routed
6688 separately in the same function earlier. Affects file
6689 silcd/packet_send.c and all channel packet sending functions.
6691 * In USERS reply, res_argv[i] are not allocated, the table
6692 is allocated. Thus changed that free the table, not its
6695 * In server's whois_check and identify_check if the client is
6696 locally connected do not send any WHOIS commands - they are not
6699 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Fixed some minor bugs in client when sending WHOIS command. The
6702 arguments was in wrong order.
6704 * Removed statis function add_to_channel from server in
6705 silcd/command.c that was previously used with the joining but
6708 * Tested USERS command in router environment successfully with two
6709 routers, two servers and two clients.
6711 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * Reorganized the USERS command and command reply in client library
6714 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6715 When the command is given by user we register a pending command
6716 callback that will reprocess the command after the reply has been
6717 received from the server. When reprocessing the packet we then
6718 display the information. Thus, the USERS information is displayed
6719 now in the command callback instead of in the command reply
6720 callback. The processing of the command is same as previously
6721 when server has sent the command reply in the JOINing process.
6723 * Added to USERS command in silcd/command_reply.c to join the client,
6724 we didn't use to know about, to the channel after we've created
6725 a client entry for it. Also, for clienet we did know already still
6726 check whether it is on the channel or not and add it if not.
6728 * Removed silc_server_command_join_notify as the function and its
6731 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6733 * Changed the client's pending command handling to the same as the
6734 server's pending command handling. It is also now possible to
6735 execute command reply functions from other command reply
6736 function as the function callbacks for commands and command
6737 replies are one and same. The pending commands are not static
6738 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6739 in client connection context. Thus, pending commands are server
6740 connection specific as it is convenient.
6742 Changed the function silc_client_command_pending and
6743 silc_client_command_pending_del and added new function
6744 silc_client_command_pending_check. Removed the
6745 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6748 * Added cmd_ident, current command identifier, to the client
6749 connection context in lib/silcclient/client.h to keep track on
6750 command identifiers used in command sending. Client's command reply
6751 function handling now supports the mandatory command identifiers.
6753 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6754 funtions in client to fully support pending command callbacks.
6756 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6757 as one of the arguments to the application in the command reply
6760 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6761 before first releasing SILC but came back. Now it is removed again
6762 and should come back nomore. The FORWARDED flag was used only
6763 by the JOINing procedure by forwarding the command packet to router.
6764 Now, the JOINing procedure has been changed to more generic (due
6765 to various router environment issues) and FORWARDED is not needed
6766 anymore for anything. The protocol specification is yet to be
6769 Now, removed silc_server_packet_forward from server and the flag
6770 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6772 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Renamed NAMES command to USERS command. The NAMES was named that
6775 due to historical reasons. Now it is renamed. Also, rewrote
6776 parts of the USERS command. The nickname list is not sent anymore
6777 by the server. Only Client ID and mode lists are sent in the USERS
6778 command. Changed this also to the protocol specification.
6780 The client now resolves the names and stuff after it receives
6781 the USERS list from the server when joining to the channel.
6783 * WHOIS and IDENTIFY commands has been changed to support multiple
6784 Client ID's per command. One can now search for multiple users
6785 in the network by sending only one WHOIS or IDENTIFY command.
6786 Changed the code and the protocol specifications.
6788 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6789 uses silc_server_command_whois_parse to parse the request. */
6791 * If normal server, do not parse the WHOIS and IDENTIFY requests
6792 before sending it to the router. Saves some time.
6794 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Fixed JOIN command on client library. Wrong number of arguments
6797 used to crash the client.
6799 * Added silc_server_channel_has_global function to check whether
6800 channel has global users or not.
6802 * Added silc_server_channel_has_local function to check whether channel
6803 has locally connected clients on the channel.
6805 * The silc_server_remove_from_one_channel now checks whether the
6806 channel has global users or not after given client was removed from
6807 the channel. It also checks whether the channel has local clients
6808 on the channel anymore. If it does not have then the channel entry
6809 is removed as it is not needed anymore.
6811 * The silc_server_notify now checks on JOIN notify whether the joining
6812 client is one of locally connected or global. If it is global then
6813 the channel has now global users on the channel and that is marked
6814 to the channel entry. Also, it now saves the global client to
6815 global list who is joining and JOINs it to the channel. This is
6816 for normal server, that is.
6818 Changed silc_server_send_notify_on_channel,
6819 silc_server_packet_relay_to_channel and
6820 silc_server_packet_send_to_channel check if we are normal server
6821 and client has router set (ie. global client) do not send the
6822 message to that client, as it is already routed to our router.
6824 * Implemented LEAVE notify type handling in silc_server_notify
6827 * Tested LEAVE command in router environment successfully. Tested
6828 with two routers, two servers and two clients.
6832 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6834 * Implemented SIGNOFF notify type handling in silc_server_notify
6837 * silc_server_remove_id now removes the client entry from all channels
6838 it has joined and thusly sends SIGNOFF notify type.
6840 * Rewrote the NAMES list generation in server by removing two excess
6841 loops. The lists are created now inside one loop.
6843 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * silc_server_remove_channel_user checks now also global list
6846 for channel and client.
6848 * silc_server_new_channel_user checks now both local and global
6849 list for channel and client. Fixed a bug in client id decoding.
6850 Used to decode wrong buffer.
6852 * silc_server_channel_message checks now both local and global
6853 list for channel entry.
6855 * Tested channel joining (hence JOIN) in router environment
6856 successfully. Tested with two routers, two servers and two
6859 * Tested channel message sending in router environment successfully.
6861 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Added silc_server_save_channel_key into server.[ch] to save the
6864 received channel key in Channel Key payload processing. It is
6865 also used in JOIN command reply handling.
6867 Equivalent function silc_client_save_channel_key added into
6868 client.[ch] into client library.
6870 * Changed JOIN command reply to send information whether the channel
6871 was created or not (is existing already) and the channel key
6872 payload. Changed protocol specs accordingly.
6874 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6875 the request was sent by ID and not by nickname. Crashed on
6878 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6881 now correctly save the received data.
6883 * silc_server_free_sock_user_data now notifies routers in the
6884 network about entities leaving the network.
6886 At the same time implemented functions silc_server_remove_id
6887 and silc_server_send_remove_id to receive and send REMOVE_ID
6888 packets. The packet is used to notify routers in the network
6889 about leaving entities. The ID removed will become invalid in
6892 * Added function silc_idlist_del_server into server. Removes and
6893 free's server entry from ID list.
6895 * silc_server_private_message function now checks, if we are router,
6896 that the destination ID really is valid ID, naturally.
6898 * In router when NEW_ID packet is received (for new client) the
6899 hash of the Client ID is saved in the ID Cache but the
6900 client->nickname is set to NULL, instead of putting the hash
6903 IDENTIFY command now also checks that client->nickname must be
6904 valid. If it is not if will request the data from the server who
6905 owns the client. Added new function
6906 silc_server_command_identify_check.
6908 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6909 to set the command to already allocated Command Payload.
6911 * Tested private message sending in router environment with two
6912 routers, two servers and two clients. Fixed minor bugs and now
6915 * Fixed segfault from client's NAMES command. Used to crash if
6918 * Forwarded packets must not be routed even if it is not destined
6919 to the receiver. Changed server code comply with this.
6921 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6923 * Added `require_reverse_mapping' boolean value to ServerParams
6924 structure. If TRUE (not default) the server will require that
6925 the connecting host has fully qualified domain name.
6927 If the reverse mapping is not required and hostname could not be
6928 found the IP address is used as hostname.
6930 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6932 * Implemented version string checking to both client and server.
6933 The check is incomplete currently due to the abnormal version
6934 strings used in development version of SILC.
6936 * Changed all command functions in server to use the new
6939 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Changed char *data to unsigned char *data in ID Cache system to
6942 support binary data as ID Cache data. Changed code to support
6943 binary data in lib/silccore/idcache.c.
6945 * Renamed silc_server_packet_relay_command_reply to
6946 silc_server_command_reply as it is normal packet receiving
6947 function. Rewrote the function to accept command replys for
6948 servers and not only for clients.
6950 * Mark remote router always as registered server if we are connecting
6951 to it. Otherwise, commands sent by the router to us are ignored.
6953 * All ID List find routines now returns the ID Cache Entry pointer
6954 as well if requested.
6956 * WHOIS command works now in router environment, tested with two
6957 routers, two servers and two clients.
6959 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6960 in router environment (as it is almost equivalent to WHOIS) but
6961 hasn't been tested thoroughly. Added new functions:
6963 silc_server_command_identify_parse
6964 silc_server_command_identify_send_reply
6965 silc_server_command_identify_from_client
6966 silc_server_command_identify_from_server
6968 * Disabled route cache adding because adding two different ID's with
6969 same IP replaces the old cache entry thus giving wrong route.
6970 The entry->router->connection is always the fastest route anyway
6971 so route cache may not be needed. Of course, new routes maybe
6972 established after receiving the ID when the entry->router->connection
6973 might not be anymore the most optimal.
6975 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Add route cache for received ID for fast routing.
6979 * Added silc_server_packet_route to route received packet on router
6980 that is not destined to us.
6982 * Renamed silc_server_get_route to silc_server_route_get.
6984 * Added id_string and id_string_len fields into SilcServer to
6985 include encoded ServerID for fast comparing without excess
6986 encoding of the ID's.
6988 * Cleaned up WHOIS command on server side. Added following static
6991 silc_server_command_whois_parse
6992 silc_server_command_whois_check
6993 silc_server_command_whois_send_reply
6994 silc_server_command_whois_from_client
6995 silc_server_command_whois_from_server
6997 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6998 arguments in command replies. All command functions should be
6999 updated to use this macro.
7001 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Minor typo fixes on command reply handling on server.
7005 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Added silc_server_command_add_to_channel internal routine to add
7008 the client to the channel after router has created the channel and
7009 sent command reply to the server.
7011 * Added generic silc_server_send_command to send any command from
7014 * Use static buffer with ID rendering instead of duplicating data.
7016 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Fixed a channel user mode bug when joining to a channel server gave
7019 everybody channel founder rights, oops.
7021 * We mark ourselves as the router of the incoming server connection
7022 if we are router ourselves. This way we can check in some packet
7023 sending functions whether it is locally connected server. For
7024 incoming router connections we put NULL.
7026 * For router sending packets locally means now always sending the
7027 packet cell wide; to local clients and local servers. For normal
7028 server sending packet locally means sending it to only local
7031 * Fixed the JOIN command to really work in router environment. If the
7032 channel is created it is always created by the router. Router is
7033 also responsible of making the initial joining to the channel,
7034 sending JOIN notify to the sending server and distributing
7035 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7036 does not exist server doesn't do anything else but forward the
7037 command to the router which performs everything.
7039 * Added silc_server_send_channel_key function to send the Channel Key
7042 * Added silc_server_create_channel_key to create new channel key. The
7043 channel key is now re-generated everytime someone joins or leaves
7044 a channel, as protocol dictates. Note: channel->key_len is the
7047 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7050 packet_receive.[ch] to separate packet sending and receiving
7051 routines. The server.[ch] now includes everything else including
7052 actual packet processing (writing and reading data) and other
7055 Renamed silc_server_private_message_send_internal to
7056 silc_server_send_private_message. The routine is still though
7057 used only to relay private messages as server does not send
7058 private messages itself.
7060 Renamed silc_server_new_channel to silc_server_create_new_channel
7061 and added new function sicl_server_new_channel that handles the
7062 incoming New Channel packet. Added also new sending function
7063 silc_server_send_new_channel to send New Channel Payload.
7065 * Added new function silc_server_notify to process incoming notify
7066 packet to the server/router. Server may then relay the notify
7067 to clients if needed.
7069 * Added new function silc_server_new_channel_user to process incoming
7070 New Channel User packet. Router will redistribute the packet and
7071 send JOIN notify to its local clients and locally connected servers
7072 if needed. Normal server will send JOIN notify to its local client
7073 on same channel when received this packet. Added also corresponding
7074 sending function silc_server_send_new_channel_user to sent the
7077 * Added boolean route argument to send_notif_to_channel and
7078 packet_send_to_channel functions to attempt to route the packet
7079 if it is TRUE and send only locally if it is FALSE.
7081 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * silc_server_replace_id now broadcasts the received replace ID
7084 packet if it is not broadcast packet already. The router must
7085 broadcast to inform other routers about changed ID.
7087 * Added backpointer to server's router into SilcServer context in
7088 silcd/server_internal.h.
7090 * Fixed silc_server_packet_broadcast to send correct broadcast
7093 * The channel key is now distributed to the local client as soon
7094 as it is received from the router (in router environment) so that
7095 no other packet may be sent for the channel until client has
7098 * silc_server_remove_channel_user now broadcasts the received
7099 Remove Channel User packet if it is not broadcast packet already.
7100 The router must broadcast to inform other routers about removed
7103 * Added users field into SilcPacketContext that is a reference count
7104 of the context. One can increase the reference count by calling
7105 silc_packet_context_dup which is now changed to just increase the
7106 reference count instead of duplicating the data. The reference
7107 count is decresed by calling silc_packet_context_free that will
7108 free the data after the reference count hits zero.
7110 For now on the packet context and everything allocated into it
7111 (including the raw packet from network) must be freed by calling
7112 the new silc_packet_context_free function. Added also new function
7113 silc_packet_context_alloc that must be used now to allocate the
7114 context. This also means that if a routine is asynchronous from
7115 silc_[client/server]_packet_parse_type the packet context must
7116 be duplicated by calling silc_packet_context_dup. Otherwise it
7117 gets free'd after silc_[client/server]_packet_parse_type returns.
7118 Also, one must remember that if packet is duplicated then its
7119 reference count must be decresed by calling the free function as
7120 many times as it was duplicated.
7122 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7123 from both client and server.
7125 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Made joining to a channel working in router environment.
7129 * Cleaned up JOIN command on server side and create function
7130 silc_server_command_join_channel internal routine to make the
7133 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * Changed silc_command_pending list to SilcDList. Also, added
7136 `ident' field to SilcServerCommandPending structure to identify
7137 the reply and to call correct callback.
7139 Added silc_server_command_pending_check function to replace the
7140 corresnponding macro. The silc_command_pending list is not
7143 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7144 to set identifier to previously allocated Command Payload. It
7145 is used to set identifier for command when resending Command
7148 * Added silc_command_payload_encode_payload to encode Command
7149 Payload buffer from SilcCommandPayload structure.
7151 * Added silc_argument_payload_encode_payload to encode Argument
7152 payload buffer from SilcArgumentPayload structure.
7154 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7156 * Changed WHOIS command to support router connection on server side.
7157 The whois request is always sent to router unless the server is
7158 standalone server. After server has received the reply from the
7159 router will it send the reply to the client.
7161 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7162 broadcast received broadcast packet. The function is used only
7163 by router. The broadcast packet is always sent to the router's
7166 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7167 render given ID to printable string, for log files for example.
7169 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Made basic router to router connections working. At least they
7172 can now connect to each other but nothing really works the way
7173 they are supposed - yet.
7175 * Added new initiator token to RouterConnection configuration
7176 file in silcd/serverconfig.[ch]. It is used to tell whether we
7177 are the initiator to the remote router or whether we'll expect
7178 the other end to connect.
7180 * Moved registering of listener task to silc_server_init, hence
7181 the server starts listenning as soon as it is run, even if it
7182 does not have connections to other routers. Let's see how well
7185 * Changed default connection retry timeouts for more suitable in
7188 * Removed cipher and such arguments from silc_idlist_add_client
7189 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7190 Added new function silc_idlist_add_data to add the keys and stuff
7193 * Added SilcIDListData structure and added it to SilcClientEntry
7194 and SilcServerEntry as their first field in the structure. This
7195 way we can explicitly cast the ID entries to the SilcIDListData
7196 structure and get common data for the entries. In past, we had
7197 to first check what type of connection it is and then cast it to
7198 correct ID entry type. Now, we can directly cast the opaque
7199 pointer to the SilcIDListData (no matter what ID entry it actually
7200 is) and get the data needed.
7202 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7204 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7205 in some circumstances even if threre were timeout tasks, though not
7206 IO tasks, but tasks anyway. Now fixed.
7208 * Defined SilcServerConnection structure to hold connection specific
7209 stuff about directly connected servers and routers. The definition
7210 is currently in silcd/server_internal.h. I thought about having
7211 a bit more important role fro this struct but for now it is used
7212 only when connecting to other server (or router actually).
7214 * Added connecting retry support in server when connecting to
7215 router(s). The retry feature implement exponential backoff
7216 algorithm. Also, added SilcServerParams structure to hold default
7217 parameters for server. For now, it include these retry settings
7218 and are hard coded. After server is moded to be as Silc Server
7219 Library this structure will be more important.
7221 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Changed client librarys channel->clients table to SilcList and
7224 changed code accordingly.
7226 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Changed client's channel table to SilcList and changed code
7229 accordingly. Also changed SilcChannelClientEntry to include back-
7230 pointer to the channel so that client entry can use that structure
7231 as list as well and we have fast cross-reference to the channel.
7232 This change dramatically decreased the complexity of channel
7233 handling with client entry and vice versa (removed one extra
7234 loop when searching for channel entry from many functions).
7236 * Changed server->sim from table to SilcDList and changed code
7239 * NAMES command can now be used from user interface. It will show
7240 the user list on the channel, neatly.
7242 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7243 Code now saves realname of the user if it becomes available.
7245 * Renamed configure.in to configure.in.pre and made ./prepare
7246 script to automatically add correct version string to
7247 configure.in which it creates from configure.in.pre.
7249 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * NAMES command reply now shows users mode with the nickname when
7254 * Moved silc_client_ch[u]mode[_char] functions from
7255 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7256 place sucks, they are utility functions and should be in some
7259 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7261 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7264 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Added TRQ (efficient deque and list library) into lib/trq. This is
7269 a very good list library that is currently used in the SILC. Defined
7270 SilcList API over the library because I didn't like the API very
7271 much. See lib/trq/silclist.h for the API and examples of how to
7272 use the API. Fixed various places in the code to use the new
7273 SilcList API. The SilcList is meant for lists that has a structure
7274 already defined as a list. It is not suitable to add just some
7275 context to the list (in TRQ, the context is the list actually).
7277 So, I defined SilcDList that can be used for the purpose where
7278 predefined list structure does not exit. This can be used as
7279 such list. Now some context just can be added to the SilcDList.
7280 Currently this list is not used in the SILC just yet, though there
7281 are a lot places where this can replace dynamically allocated
7282 tables and I will fix these places, later, to use SilcDList.
7283 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7284 and use TRQ internally).
7286 Also fixed some annoying warning messages that the original TRQ
7287 code generated. Also minor changes to TRQ's Makefile.in.
7289 * Added support for querying by Client ID to both WHOIS and
7290 IDENTIFY commands into server, as required by the protocol.
7292 * Removed method function pointers from SilcBuffer structure. They
7293 weren't used to anything and just increased the context size for
7294 no good reason. This change also made silc_buffer_alloc and
7295 silc_buffer_free functions inline functions.
7297 * Disabled command flooding detection support until it's fixed so
7298 that it accepts commands in but does not execute them more than once
7301 * Added silc_net_localhost(), to return local hostname, into
7302 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7303 that must be initialized before calling silc_client_init.
7305 * Added new function: silc_server_send_notify_on_channels to send
7306 notify messages to all channels client has joined. It is assured
7307 that the message is sent only once per client.
7309 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7310 lib/silcutil/silcutil.[ch] as silc_format function. The new
7311 function is generic and is used by server as well, not only by
7312 the logging routines.
7314 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7315 the provided version string was not acceptable. Added new function:
7316 silc_ske_check_version into lib/silcske/silcske.h. The function
7317 must be implemented by the application (client or server) and it
7318 does not reside in the SKE library. The function checks the version
7319 string remote end sent.
7321 * Added back pointers (to opaque context and to SilcSocketConnection)
7322 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7324 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7325 duplicate packet context structure.
7327 * Changed `notify' client operation to send same arguments as client
7328 receives from server except for ID's. ID's are mapped to correct
7329 ID entry and that is returned. Also, if channel entry is not sent
7330 by server but the notify is for channel the channel entry is sent
7331 to application (otherwise application doesn't know that it is for
7332 channel (library gets it from packet's Destination ID)).
7334 * Added silc_client_remove_from_channels into client library to
7335 remove a client from all channels it has joined to. Used when
7336 received SIGNOFF notify from server. Added also new function
7337 silc_client_replace_from_channels to replace old ID entry with
7338 new ID entry on all channels. Used when received NICK_CHANGE
7341 * Fixed ID Cache list handling in silc_idlist_get_client in
7342 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7343 to get (or query) client by ID.
7345 * Updated TODO list.
7347 * Added connection authentication status message defined by the
7348 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7349 support for these into the code in client and server side.
7351 * Added generic function silc_client_send_command to send any command
7352 with variable argument list. Application should use this function
7353 to send commands if the command functions provided by the library
7354 does not suite for the application's user interface needs.
7356 * Added new `failure' client operation. Application is notified about
7357 received failure packet if client is executing a protocol. In this
7358 case the protocol's execution has failed.
7360 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7361 is required by the protocol.
7363 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7364 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7367 * Added status flag to SilcSKE object to indicate realtime status
7368 of the SKE protocol.
7370 * Application receives now exactly same command reply arguments as
7371 the library receives from server. However, if ID is received the
7372 corresponding ID entry is returned to the application (eg. Client
7373 ID is mapped to correct SilcClientEntry entry and that is returned).
7374 Changed command_reply client operation due to this change.
7376 * Changed all ID's in commands and in command replys as ID Payloads.
7377 Change affected both client and server side codes.
7379 All ID's sent in SILC network (with execption of ID's in SILC
7380 Packet header) are sent in ID Payload to support variable length
7383 * Server now notifies nick changes and notifies all clients on
7384 the channels about the new nickname (about the new Client ID,
7387 * Implemented CMODE command to change channel modes. Supports all
7388 channel modes defined by the protocol specs except ban and invite
7389 lists. (Also, private channel key mode is supported but support for
7390 setting private channel key in client is missing, thus, this mode
7391 has no effect on client side (except that server requires that the
7392 client uses private channel key and normal channel traffic does not
7395 Also, invite mode works per se, but INVITE command does not work
7396 yet correctly, so you can set channel as invite only channel but
7397 inviting clients to the channel does not work (it is yet to be
7398 thought what's the best way to do it).
7400 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7401 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7402 Implemented CUMODE command to change user's mode on the channel.
7403 Supports all modes defined by the protocol specs.
7405 * Added NAMES command reply to return users modes on the channel.
7407 * Removed unnecessary and slow ciphers from lib/silccrypt.
7409 * Set SO_KEEPALIVE option to connection sockets by default.
7411 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7413 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7414 redefined the Notify Payload into protocol specs.
7416 * Added silc_id_payload_parse_id to get ID directly from raw
7419 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7422 accept searching by Client ID as well.
7424 * Added support for LEAVE and SIGNOFF notify types in client library.
7426 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7427 to parse ID Payload from raw data.
7429 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Added flags parameter into silc_ske_assemble_security_properties
7432 function in lib/silcske/silcske.[ch].
7434 * Changed notify client operation to fit better for notify messages
7435 sent by server. The notify payload received from server is now
7436 passed to the application (after parsing it to SilcNotifyPayload).
7437 It is application's responsibility to retrieve the arguments
7438 from the payload and show the message the way it wants. The message
7439 sent by server is implementation specific.
7441 * Changed public keys to comply with the protocol specification.
7442 Old public keys are not supported anymore and are not compatible.
7444 * Removed nickname from Channel Payload as the latest draft removed
7445 it. The client must resolve the nickname from the NAMES command
7446 reply received when it joined the channel.
7448 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7450 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7452 * Fixed some errors in protocol specification drafts.
7454 * Created lib/silccore/silcnotify.c to implement Notify Payload
7455 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7456 generic payloads described by protocol specifications. The file
7457 includes implementations for ID Payload and Argument Payload.
7459 * Changed Command Payload implementation to use the new Argument
7460 Payload. Changed command_xxxx_payload to command_payload_xxxx
7461 to comply with SILC coding conventions.
7463 * Added suppport for Argument Payload handling in Notify Payload
7464 implementation as protocol requires it. Added the new support
7465 into server and client lib as well.
7467 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7469 * Added support for multiple nicknames on same channel. [n] is
7470 added locally to the nickname if there are more than one same
7471 nicknames on the channel.
7473 * Server now sends all nicknames that matched WHOIS request.
7474 Client also shows the list received from server.
7476 * Added TOPIC command to client side. User can now set and show
7477 current topic on channel.
7479 * Added MOTD command to client and server. Also, server sends the
7480 motd when client connects to the server.
7482 * Changed version strings to comply ISO 8601.
7484 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7486 * Fixed protocol error handling in client library. It should now
7487 cope even if the SKE fails for some reason.
7489 * Made new protocol specification drafts for submitting to IETF.
7491 * Implemented TOPIC command to server in silcd/command.c.
7493 * Added two new notify types into lib/silccore/silcnotify.h:
7494 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7495 notify nickname change and topic setting/change on a channel.
7497 * API change of command_reply operation in client library. The
7498 application gets now the status type received from server as well.
7500 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7502 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7504 * Cras fixed and optimized the packet handling even further and
7505 it should work now. Minor change to the prototype of function
7506 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7508 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Added new function into lib/silcutil/silcschedule.[ch]:
7511 silc_schedule_with_fd to select() a specified fd. The function
7512 returns after timeout expires or data arrives or goes. The
7513 function is used by packet routines to wait that all data is
7514 received from network.
7516 * Fixed data reading from network in lib/silccore/silcpacket.c.
7517 The code now assures that all data is read from the fd and then
7518 continues packet processing. This was a bug fix since the code
7519 used to drop some data in some circumstances.
7521 * Added new function into lib/silcclient/client.[ch]:
7522 silc_client_start_key_exchange to start key exchange after
7523 connection has been established to server. The code internally
7524 now uses this funtion but its main purpose was to provide it
7525 for applications that perform their own connecting. After
7526 application has created a connection it merely calls this
7527 function to start the key exchange between client and server.
7528 The library takes care of everything else after that.
7530 Updated also lib/silcclient/README to explain the usage of
7533 * Do not send to application information that connection has
7534 been established. Application gets notified it by connect
7537 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7539 * Applied cras's patch to add silc_schedule_one function. The
7540 function runs scheduler once and returns.
7542 * Fixed the scheduler after cras messed it up. The timeout
7543 handling works now as it's supposed to work.
7545 * Added into lib/silccore/ silcnotify.h to include notify
7546 message types support. Changed silc_server_send_notify*
7547 functions, in server.[ch], to support those new notify types.
7548 Added the support for the notify types into client library,
7549 as well. Added new notify client operation into ops.h in
7552 * Changed silc_server_packet_send_to_channel to send normal
7553 packets instead of just channel message packets. The function
7554 is now used to send the notify packets to channels. It is not
7555 used to send channel message packets anymore, as server never
7558 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7559 va_arg()s as it seems to require it nowadays. I guess, if SILC
7560 is compiled with older va_arg() the new code should work anyway.
7562 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7564 * Splitted core library. Core library (lib/silccore) includes
7565 now only SILC protocol specific core (and common) components.
7566 Created new utility library (lib/silcutil) that includes more
7567 generic purpose stuff. The stuff for util library was taken
7568 from the old core library. This was minor and easy split.
7570 * Created SILC Client Library (lib/silcclient) that includes
7571 implementation of the SILC client without user interface. This
7572 was major move from silc/ directory. The code has been changed
7573 so that it is transparent towards the user interface. The
7574 silc/ directory includes now the same user interface as before
7575 and it uses the new client library. Read lib/silcclient/README.
7576 Basicly, the client library performs everything else related
7577 to SILC except user interface handling. Also, configuration
7578 files are considered to be part of user interface and library
7579 does not handle them.
7581 This change also changed a lot of structures, function naming etc.
7582 Most important change was that SilcClientWindow object was
7583 renamed to SilcClientConnection in the client library. Created
7584 also new file lib/silcclient/ops.h. Also added new files
7585 silc/local_command.[ch] and silc/client_ops.[ch].
7587 All these changes were made to make it easier for user interface
7588 designers to create what ever user interface for the SILC client
7591 It is also expected that the server will be moved to lib
7592 directory as well and SILC Server Library will be created;
7593 sometimes in the future.
7595 * Removed Local commands from lib/silccore/silccommand.h as
7596 they are application specific and new client library does not
7597 handle any of those anymore.
7599 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7600 old client implementation in silc/.
7602 * Added support for callback functions in SILC_LOG_* macros.
7603 Application can now set its own callbacks that will be called
7604 instead of using the default functions that will always print
7605 the debug messages to stderr (or stdout). Also, debugging can
7606 now be disabled by setting silc_debug to FALSE and re-enabled by
7607 setting it to TRUE. Note, that logging will still work even
7608 if debugging is disabled.
7610 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7611 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7612 silc_log_reset_debug_callbacks.
7614 * To enable debugging in silc client one must give now -d
7615 option on command line.
7617 * Changed silc_schedule_init to automatically allocate task queues
7618 if they are not allocated before calling it.
7620 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7622 * Added GMP 3.1 into math library.
7624 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7627 a channel in SILC network. The packet is used by servers and
7628 routers to notify other routers that user has left a channel.
7629 This little feature was missing until now. Added the feature
7630 to protocol specification as well.
7632 Added functions: silc_server_send_remove_channel_user and
7633 silc_server_remove_channel_user into server.[ch].
7635 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7636 lib/silccore/silcpacket.h. However, they are not implemented
7639 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7641 * Fixed joining to a channel and sending channel messages
7642 between server and router. The channel message sending should
7643 now work inside a cell.
7645 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7647 * Fixed the private message sending between server and router.
7648 The private message sending should now work inside a cell.
7650 * Added silc_server_replace_id into server.[ch] to replace
7651 existing ID in the SILC network.
7653 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7654 and silc_idlist_replace_server_id into idlist.[ch] in server.
7656 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Fixed the server to server connections. Server can again now
7659 connect to router. Router to router connections probably does
7662 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7664 * Added dynamic protocol registering support. Now protocols can
7665 registered and unregistered on the fly. Patch by cras.
7667 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7669 * Added lib/contrib directory to hold routines that some platforms
7670 don't have but are needed by SILC.
7672 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7673 into lin/contrib to provide getopt() and getopt_long() for
7674 those who don't have it.
7676 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7678 * Added AWAY command to client. When away message is set and
7679 client receives a private message packet the client automatically
7680 replies to the sender with the away message.
7682 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7683 bug seemed to be the cause of recent problems when compiling
7686 * Added version detection support to SKE protocol specification
7687 and added the new changes to the SKE implementation as well.
7688 There were other minor changes in the SKE protocol as well.
7690 Many changes in lib/silcske/silcske.[ch] and in
7691 lib/silcske/payload.[ch].
7693 * Added ^U functionality, clear input line. Patch from cras.
7695 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Mainly small bugfixes on core library. Fixed some debugging
7698 logging and buffer overflow in silclog.c.
7700 * Updated config.sub and config.guess on the distribution tree.
7702 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7704 * Added command lagging support in server. Client may execute
7705 commands now only once in two seconds.
7707 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7709 * Optimized packet reception. MAC computation and checking is now
7710 also more optimized. A lot previously duplicated code is now
7711 used as generic by both client and server.
7713 * Fixed key pair generation in clientutil.c
7715 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7717 * Added into lib/silccore/silcbufutil.[ch] new function;
7718 silc_buffer_realloc.
7720 * Moved generic packet sending/encryption functions to
7721 lib/silccore/silcpacket.[ch] from client and server. Some
7722 rewriting of the functions.
7724 * Moved all generic packet reception/decryption functions to
7725 lib/silccore/silcpacket.[ch] from client and server. The
7726 packet processing is now much cleaner in both client and server.
7727 These were major changes in both client and server.
7729 * Created many common functions in server to do packet sending.
7730 Previously code were duplicated a lot, this has been removed
7733 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7735 * Rewrote major parts of the ID cache system. Don't know
7736 whether it is better now or not but at least the API is more
7739 * Major rewrite on ID cache stuff on client because of the ID
7740 cache API changes. Added idlist.c to client.
7742 * Also major rewrite on ID cache stuff on server as well.
7743 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7744 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7745 in hand, instead they are all put into the ID cache system now.
7746 All server_idlist_* routines uses ID cache now instead of
7747 traversing its own lists (those lists does not exist anymore).
7748 SilcIDList though still exists. Also, SilcXXXEntry's are
7751 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7753 * Finally made the SKE implementation compliant to the protocol
7754 specification. All mp integers are now binary encoded as
7755 opposed being HEX encoded.
7757 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7760 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7761 functions: silc_[encode/decode]_pem. Also added function
7762 silc_encode_pem_file to PEM encode with newlines ('\n') for
7765 * SILC public keys are now encoded either PEM or binary. Same
7766 option is for private keys as well. By default private keys
7767 are binary encoded and public keys PEM encoded. Silly HEX
7768 encoding were removed.
7770 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7771 function to create fingerprints.
7773 * Fixed a bug in SHA1; does not change the original data anymore.
7775 * Partly implemented INFO command on client and server side.
7776 Fixed CLEAR command. Changes to SERVER command; show current
7777 server(s) when giving command without arguments. Added
7778 VERSION command to client.
7780 * Added check to server that unregistered connections cannot
7781 execute commands (unless it is specificly allowed).
7783 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * Fixed screen refresh.
7787 * Fixed channel joining bug from client. On some circumstances
7788 client tried to join to a channel it had already joined.
7790 * Added public key verification process into client's protocol.c.
7791 The client now verifies the public key from user and saves
7792 it into ~./silc/serverkeys/ directory.
7794 Added into: clientutil.[ch]: silc_client_verify_server_key.
7796 * Changed SKE protocol's silc_ske_initiator_finish function
7797 to accept callback function that verifies the received public
7798 key. Removed old silc_ske_verify_public_key function.
7800 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7802 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7803 silc_pkcs_private_key[_data]_set.
7805 * Made the password and public authentication more cleaner in
7806 server's protocol.c.
7808 * Removed historic and obsolete protocol `channel_auth' from
7809 both client and server.
7811 * Removed wrong way of sending command status messages from
7812 server to client in server's command.c. The old way violated
7813 protocol specification.
7815 Changes to silccore/silccommand.[ch]: removed
7816 silc_command_encode_status_payload -> not needed anymore,
7817 changed silc_command_encode_payload_va to accept extra
7818 argument on variable argument list. The argument type must
7819 now be provided to the function. Also, added new function:
7820 silc_command_encode_reply_payload_va which is same as
7821 normal command_encode_payload_va except command status type
7822 is provided as extra argument.
7824 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7826 * Added ~./silc directory handling. The directory includes the
7827 public and private keys for the client.
7829 Added silc_client_check_silc_dir, silc_client_create_identifier
7830 and silc_client_load_keys.
7832 * Implemented SILC protocol compliant public key. Added public
7833 and private key saving to and loading from files.
7835 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7836 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7837 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7838 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7839 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7841 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7842 silc_pkcs_load_[public/private]_key.
7844 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7846 * Added silc_server_get_route (route.[ch]) to get connection
7847 data for the fastest route for given ID.
7849 * Implemented INVITE command on client and server. The command
7850 were re-defined in the SILC Protocol Specification and the
7851 implementation now complies with the specification.
7853 * Implemented PING command on client and server.
7855 * Implemented NAMES command on client and server. The server side
7856 supports currently only normal server not router server yet.
7857 Some changes to NAMES definition in SILC protocol specification.
7859 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7861 * Implemented LEAVE command on client and server.
7863 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7864 again. This change was made to the protocol as well. Server
7865 should not violate the protocol specification anymore.
7867 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7869 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7870 was tested. SOCKS4 was not but should work anyway.
