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

694 * Added `user_count' to the SilcChannelEntry which now tells the
695 number of users on the channel. The user count is now saved
696 in normal server of global channels as well. Affected files
697 silcd/server.c, idlist.h, packet_receive.c and command.c.
699 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

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

790 * Added new configuration options and blocks:
791 keepalive_secs, reconnect_count, reconnect_interval,
792 reconnect_interval_max, reconnect_keep_trying and
793 require_reverser_lookup. Added ConnectionParam block, and
794 implemented the connection parameters when connecting as
795 initiator and when accepting connections as responder.

798 whether given configuration value has been given already.
800 Affected files silcd/serverconfig.[c], server.[c].
802 * Splitted the doc/example_silcd.conf.in. Separated the crypto
803 algorithm parts and created new file silcalgs.conf, that
804 is now included from the example_silcd.conf.in.
806 * Optimized the silc_server_connect_to_router_second to take
807 the connection configuration object from the SilcServerConnection
808 object instead of finding it during the connecting phase.
809 Added the configuration object to SilcServerConnection struct.
810 Affected files silcd/server_internal.h, server.c.
812 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

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

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

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

999 lists correctly. Affected file silcd/command.c.
1001 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1003 * When sending JOIN command to router for processing the
1004 sender's old command identifier was not saved back to the
1005 sender's command context, fixed now. The affected file is
1008 * Create the key in JOIN command of the router did not return
1009 the channel key, added check for this. Affected file is
1012 * Fixed a channel ID update bug in JOIN command reply. Do
1013 not directly upgrade the ID but call the function
1014 silc_idlist_replace_channel_id if the ID was changed.
1015 Affected file silcd/command_reply.c.
1017 * Fixed memory leaks from command calling if it would fail.
1018 Affected file silcd/command.c.

1045 functions. Affected file silcd/server.c.
1047 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1048 which ID was changed. This way the router will send the
1049 user list for the channel again, and server won't be in
1050 desync in some rare circumstances. Affected file is
1051 silcd/packet_receive.c.
1053 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1082 file silcd/packet_receive.c and silcd/command.c.
1084 * Fixed the SERVER_SIGNOFF notify handling on normal server
1085 not to save the history information for clients. Same was
1086 fixed earlier in remove_clients_by_server function, but not
1087 here. Affected file silcd/packet_receive.c.
1089 * Raised the default connection-retry count from 4 to 7 in
1090 server. Affected file silcd/server.h.
1092 * Cancel any possible reconnect timeouts when we start the
1093 key exchange. Affected file silcd/server.c.
1095 * Do not reconnect on connection failure when SCONNECT was
1096 given. Affected files silcd/server.[ch].
1098 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1100 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1102 * Fixed the NICK command to always give the unformatted
1103 nickname to the one giving the NICK command. If unformatted
1104 nickname is cached already it will be formatted and the
1105 local entry will always get the unformatted nickname.
1106 Affected file lib/silcclient/idlist.c.
1108 * Fixed some double frees from client library commands.
1109 Affected file is lib/silcclient/command.c.
1111 * Fixed CUMODE command in server to assure that no one can
1112 change founder's mode than the founder itself, there was a
1113 little bug. Affected file silcd/command.c.
1115 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1117 * Removed the SilcClientCommandDestructor from the client
1118 libary, it is not needed anymore. Affected files are
1119 lib/silcclient/silcapi.h, command[_reply].[ch],
1120 client_notify, idlist.c.
1122 * Fixed GETKEY command to first resolve client, and then
1123 resolve the server only if the client was not found, instead
1124 of resolving both at the same time. Affected file is
1125 lib/silcclient/command.c.
1127 * Added silc_client_start_key_exchange_cb and lookup the
1128 remote hostname and IP address before starting the key
1129 exchange with server. The affected file is
1130 lib/silcclient/client.c.
1132 * The server's public key is now saved using the IP address
1133 of the server and not the servername for the filename.
1134 The hostname public key filename is checked as an fall back
1135 method if the IP address based filename is not found.
1137 Fixed the GETKEY command to save the fetched server key
1138 in correct filename.
1140 Print the remote server's hostname now when new key is
1141 received during connection process. Affected file is
1142 irssi/src/silc/core/client_ops.c.
1144 * Return always our own public key to the client if it asks
1145 for it with GETKEY command. Affected file silcd/command.c.
1147 * Removed the use_auto_addr variable from default config
1148 file since it was in wrong section. Affected file is
1151 * Fixed TOPIC_CHANGE notification to not route it when it
1152 was sent using silc_server_send_notify_to_channel function.
1153 Affected file silcd/command.c.
1155 * Fixed silc_server_send_notify_kicked to send the kicker's
1156 Client ID also, it was missing. Affected files are
1157 silcd/command.c, silcd/packet_send.[ch].
1159 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1161 * Do not save client history information in SERVER_SIGNOFF.
1162 Fixes the bug in normal server that it does not detect
1163 the client becoming valid after the server becomes back
1164 online. Affected file silcd/server_util.c.
1166 * Added `sock_error' field into the SilcSocketConnection
1167 context. When error occurs during socket operation (read
1168 or write) the error is saved. Added also new function
1169 silc_socket_get_error to return human readable socket error
1170 message. Affected files are lib/silcutil/silcsockconn.[ch],
1171 lib/silcutil/unix/silcunixsockconn.c, and
1172 lib/silcutil/win32/silcwin32sockconn.c.
1174 * The server now prints the socket error message in the
1175 signoff for client. Affected file silcd/server.c.
1177 * Fixed the `created' channel information sending from router
1178 to server in JOIN command. Checks now whether the channel
1179 really was created or not and set it according that.
1181 Fixed the JOIN command to use the client entry's current
1182 ID during the joining procedure instead of the one it sent
1183 in the command (it is checked though), since it can change
1184 between the packet processing and command processing, and
1185 would just case unnecessary pain in the client end. Affected
1186 file silcd/command.c.
1188 * Fixed a channel key payload sending to use correct channel
1189 ID when the server was forced to change the channel's ID by
1190 router. Router sent the key payload with the old Channel ID.
1191 Affected file silcd/packet_receive.c.
1193 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1195 * Call silc_server_save_channel_key only if the key payload
1196 was provided in the JOIN command's command reply. Affected
1197 file silcd/command_reply.c.
1199 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Fixed silc_mp_sizeinbase to return the value correctly with
1202 MPI. Affected file lib/silcmath/mp_mpi.c.
1204 * Fixed the stop_server signal to correctly stop the scheduler
1205 and gracefully stop the server when SIGTERM or SIGINT signals
1206 are received. Affected file silcd/silcd.c.
1208 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1210 * Simple handling of TERM and HUP signals. Also added some log
1211 flushing call around. Affected file is
1214 * Fixed small bugs in silclog.c. Now buffering output will take
1215 effect after 10 seconds since startup: This will ensure that
1216 no important startup messages are lost. Also output redirection
1217 will preserve original format ([Date] [Type] message).
1218 Affected file is lib/silcutil/silclog.c.
1220 * Added two options to the config file, in the logging section:
1221 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1222 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1224 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Do not print the warning about log files not being initialized
1227 more than once to avoid excess logging. Affected file is
1228 lib/silcutil/silclog.c.
1230 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1231 the SIM copying in make install in Makefile.am.pre.
1233 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1235 * Rewritten silclog APIs. Globally interesting changes follows:
1236 silc_log_set_files() changed to silc_log_set_file().
1237 silc_log_set_callbacks() changed to silc_log_set_callback().
1238 ROBOdoc documented silclog header file.
1239 SilcLogCb now returns bool to wether inihibit the default
1240 handler or not (to keep the old behaviour return always TRUE).
1241 The new APIs should also fix the problem of the
1242 silcd_error.log file that was written in the current directory.
1245 Log files streams will remain opened after silc_log_set_file()
1246 call, means less CPU usage notably on high traffic servers.
1247 File streams are now full buffered, and flushed to the disk
1248 every 5 minutes, lesses HD activity and CPU usage.
1249 Messages can be redirected, allowing admins to configure
1250 one single logfile for all server messages.
1251 the silc_log_quick global variable to activate fast-logging.
1252 Affected files lib/silcutil/silclog.[ch]
1254 * Changed some code to conform new silclog APIs. Affected
1255 files are doc/example_silcd.conf.in, silcd/server.c
1256 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1259 * Fixed a memory leak that could occur in some situations.
1260 Affected file silcd/serverconfig.c.
1262 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1264 * Added the silc_client_del_client to remove the client from
1265 all channels as well. Affected file lib/silcclient/idlist.c.
1267 * Fixed the client library to correctly remove the client
1268 from all channels when the client entry is being destroyed.
1269 Affected file lib/silcclient/client_notify.c, command.c.
1271 * Added auto-nicking support to the client library. If the
1272 applicatio now sets client->nickname it will be sent to the
1273 server after connecting by the library. This way for example
1274 SILCNICK (or IRCNICK) environment variables will have effect
1275 and always change the nickname automatically to whatever
1276 it is wanted. Affected file lib/silcclient/client.[ch].
1278 * Renamed silc_server_command_bad_chars to the
1279 silc_server_name_bad_chars and moved it to the
1280 silcd/server_util.[ch]. Added also new function
1281 silc_server_name_modify_bad to return nickname that
1282 includes bad characters as new nickname without those
1283 bad characters. This check and modify is now used in
1284 silc_server_new_client when the username is initially set
1285 as nickname, so it must be checked to be valid nickname.
1286 Affected file silcd/packet_receive.c.
1288 * The nickname length is now taken from the packet for real
1289 and not trusted to strlen() since it clearly can return
1290 wrong length for nickname including bad characters. This
1291 also applies to channel names. Affected file silcd/command.c.
1293 * Removed the lib/silcsilm/modules directory. Modules are now
1294 compiled into the lib/silcsim. Fixed the copying of the
1295 modules to follow symbolic links in Makefile.am.pre.
1297 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1299 * Fixed silc_string_regexify list creation. Fixes bugs with
1300 BAN and INVITE commands in server. The affected file is
1301 lib/silcutil/unix/silcunixutil.c.
1303 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1305 * Removed the command destructor entirely from the server's
1306 command and command reply routines. It is not needed, and
1307 its usage was buggy and caused crashes. Affected files are
1308 silcd/command[_reply].[ch].
1310 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Cancel protocol and NULL sock->protocol if timeout
1313 occurred during protocol. Affected file silcd/server.c.
1315 * Cancel protocol timeouts always before calling the final
1316 callback, to assure that after final callback is called
1317 no other state will be called for the protocol anymore.
1318 Affected file silcd/protocol.c.
1320 * Print error log if incoming connection configuration could
1321 not be found. Affected file silcd/server.c.
1323 * Fixed JOIN command to correctly save the founder mode
1324 to the client on normal SILC server, when the channel
1325 was created by the router. Affected file silcd/command.c.
1327 * Fixed LIST command (hopefully) to send correct reply
1328 packets. Affected file silcd/command.c.
1330 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * The silc_packet_receive_process now returns FALSE if the
1333 read data was invalid packet, and TRUE if it was ok.
1335 The server now checks that if unauthenticated connection
1336 sends data and its processing fails the server will close
1337 the connection since it could be a malicious flooder.
1339 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1341 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * Make sure the warning about error opening a log file is
1344 printed only once and not everytime it fails (produces
1345 too much useless log). Affected file lib/silcutil/silclog.c.
1347 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1349 * Made the silc_server_daemonise() function more readable.
1350 Affected file silcd/server.c.
1352 * Pid file is now optional, the user may comment it out from
1353 the config file. Removed define SILC_SERVER_PID_FILE, we
1354 don't need a default any longer. Affected file
1355 configure.in.pre, lib/Makefile.am.pre.
1357 * Make some use of the pid file. The server now dies at startup
1358 if it detects a valid pid file on his path. The server would
1359 die anyway in this circumstance, because of the bind() failure.
1360 Affected file silcd/silcd.c.
1362 * No longer compiling lib/dotconf.
1364 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Fixed JOIN command parsing not to crash. Affected file
1367 lib/silcclient/command.c.
1369 * Fied the NICK_CHANGE notify to add the new client entry
1370 even it is resolved. This removes an <[unknown]> nick
1371 thingy bug in the client. Affected file is
1372 lib/silcclient/client_notify.c.
1374 * Do not try to allocate 0 bytes (efence does not like it)
1375 in lib/silccore/silccomand.c when encoding payload.
1377 * Do not take IRCNICK as nickname in Irssi SILC client since
1378 it is not possible to set nickname before hand connecting
1379 the server (TODO has an entry about adding auto-nicking
1382 * Changed the silc_server_command_pending to check whether
1383 there already exists an pending entry with the specified
1384 command, command identifier and pending callback. This is
1385 to fix IDENTIFY and WHOIS related crashes that may register
1386 multiple pending commands with same identifier. Affected
1387 file silcd/command.c.
1389 * Fixed the server to reconnect to the router even if it
1390 was already reconnecting and EOF was received. This to
1391 fix a possibility that the server wouldn't ever try to
1392 auto-reconnect to the router. Affected file silcd/server.c.
1394 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Fixed the server's password authentication to use the
1397 length of the locally saved password, and not the one
1398 sent in the packet. Affected file silcd/protocol.c.
1400 * Fixed same password authentication problem in the
1401 Authentication Payload handling routines in
1402 lib/silccore/silcauth.c.
1404 * Yet another password authentication problem fixed with
1405 channel password handling in silcd/command.c.
1407 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * If first character of string in silc_parse_userfqdn is '@'
1410 then do not parse it. Affected file is
1411 lib/silcutil/silcutil.c.
1413 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Fixed minor bug in IDENTIFY command reply sending, which
1416 caused various weird problems during JOIN when it was
1417 resolving names for users. Affected file silcd/command.c.
1419 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Fixed the IDENTIFY command reply sending to chech better valid
1422 clients. It was possible to send incomplete list of replies.
1423 Affected file silcd/command.c.
1425 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Added silc_client_command[s]_[un]register functions now to
1428 dynamically register the commands in client library. Removed
1429 the static table of commands. This allows the client library
1430 to call commands without causing the application to know about
1431 what commands library has called.
1433 Removed the INFO command reply kludge to detect when the command
1434 was called by library. Now library use its own command reply
1435 function for INFO command.
1437 Added function silc_client_command_call to call a command.
1438 Application can use it to call command, not access the structure
1441 Now all commands that are sent by the client library (not
1442 explicitly sent by application) use own command reply functions.
1444 Affected files around lib/silcclient/ and in
1445 irssi/src/silc/core/.
1447 * Fixed the WHOIS command reply sending to chech better valid
1448 clients. It was possible to send incomplete list of replies.
1450 Fixed the WHOIS and IDENTIFY to send the request to router
1451 if normal server did not do it and did not find any results.
1453 Affected file silcd/command.c.
1455 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Moved the internal data from SilcClient context into its
1458 own file, not accesible to application. Affected files
1459 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1460 and other files in client library.
1462 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Added doc/examples installation target in Makefile.am.pre.
1467 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1470 commands the found client entry will be removed from the
1471 cache, after notifying application about the error. Affected
1472 file lib/silcclient/command_reply.c.
1474 * Changed the /MSG to check for exact nickname user gave, and
1475 not let `nick' match `nick@host' if it is only one found. Now,
1476 user must type the exact nickname (like nick@host2) even if
1477 there are no more than one same nicks found. This is to avoid
1478 a possibility of sending nickname to wrong nickname since
1479 `nick' could match `nick@host'. Affected file is
1480 irssi/src/core/silc-servers.c.
1482 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Do not print "you are now server operator" or similar when
1485 giving /away command. Affected files are
1486 irssi/src/silc/core/client_ops.c, silc-servers.h.
1488 * Made the silc_server_command_pending_error_check to send
1489 the same command reply payload it received back to the
1490 original sender of the command. This way all arguments
1491 that was received by the server will be received by the
1492 client too. Affected file silcd/command.c.
1494 * Added the silc_idcache_add to return the created cache entry
1495 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1497 * Add global clients to expire if they are not on any channel.
1498 This is because normal server will never know if they signoff
1499 if they are not on any channel. The cache expiry will take
1500 case of these entries. This is done by normal servers only.
1501 The affected files are silcd/command_reply.c,
1502 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1504 * If server receives invalid ID notification for WHOIS or
1505 IDENTIFY and the ID exists in the lists, it is removed.
1506 Affected file silcd/command_reply.c.
1508 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1509 in client then client entry that it matches is searched and
1510 the nickname is printed on the screen for user. Affected
1511 file irssi/src/silc/core/client_ops.c.
1513 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Use cache entry expire time in the LIST command reply to
1516 purge old entries from the cache after the LIST command
1517 reply has been received. This way we don't have non-existent
1518 entries in the cache for too long. Affected file is
1519 silcd/command_reply.c.
1521 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * If we are normal server, and we've not resolved client info
1524 in WHOIS or IDENTIFY from router, and it is global client,
1525 we'll check whether it is on some channel. If it is not
1526 then we cannot be sure about its validity and will resolve it
1527 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1528 file silcd/command.c.
1530 * Search channel by name (if possible) rather than by ID
1531 in IDENTIFY command's command reply. Affected file is
1532 silcd/command_reply.c.
1534 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1536 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1537 Updated specs and implemented it. Affected file silcd/command.c,
1538 silcd/packet_send.c and silcd/packet_receive.c.
1540 * Implemented the <founder auth> payload handling in the JOIN
1541 command. If provided all conditions for channel joining
1542 except requirement to provide correct passphrase can be
1543 overrided by the channel founder. Updated the protocol specs.
1544 Affected file silcd/command.c.
1546 Added support for founder auth in JOIN command in client
1547 library. Fixed the parsing of the JOIN command now to support
1548 all options as they should be. The affected file is
1549 lib/silcclient/command.c.
1551 * Optimized the WHOIS and IDENTIFY commands to send the request
1552 to router only if it includes nicknames or other names. If
1553 they include only IDs then check the local cache first before
1554 routing. Affected file is silcd/command.c.
1556 * Added channels topic announcements. Affected file is
1557 silcd/packet_receive.c and silcd/server.c.
1559 * Fixed the silc_server_send_notify_topic_set to really destine
1560 the packet to channel. Affected file silcd/packet_send.c.
1562 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1563 library. Affected file lib/silcclient/client_notify.c.
1565 * Added UMODE announcements. Affected file silcd/server.c.
1567 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Memory leak fixes in:
1571 lib/silcutil/silcsockconn.c
1572 lib/silcske/silcske.c
1573 lib/silcske/groups.c
1575 lib/silccrypt/silcpkcs.c
1576 lib/silccore/silccommand.c
1577 lib/silccore/silcidcache.c
1582 * ROBOdoc documented the lib/silcske/groups.h file and a
1583 bit changed the interface for better.
1585 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1587 * Update the client entry context in the ID cache after
1588 nick change. Affected file lib/silcclient/command.c.
1589 Fixes the CUMODE command when regaining founder privileges,
1590 and a little WHOIS problem.
1592 * Fixed silc_net_gethostbyname to correctly call the
1593 inet_ntop. Affected file lib/silcutil/silcnet.c.
1595 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1597 * Added IPv6 support checking to the configure.in.pre, added
1598 also --enable-ipv6 option to override the check. Affected
1599 file configure.in.pre.
1601 * The silc_thread_create now calls the start function
1602 directly if threads support is not compiled in. Removes
1603 ugly #ifdef's from generic code. Affected files are
1604 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1606 * Added silc_net_gethostby[name/addr]_async to asynchronously
1607 resolve. Affected files are lib/silcutil/silcnet.[ch].
1609 * Added support for rendering IPv6 based server, client and

1618 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1619 routines. Added silc_net_is_ip[4/6]. Affected file is
1620 lib/silcutil/unix/silcunixnet.c. All routines that take
1621 address as argument now supports both IPv4 and IPv6 addresses.
1623 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1625 * Fixed LIST command reply sending in server. Affected file
1628 * Server now sends the kicker's client ID in the KICK notify
1629 to the kicked client. Affected file silcd/command.c.
1631 * The client library now parses the kickers client ID and
1632 UI displays it. Affected files lib/silcclient/client_notify.c
1633 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1635 * Made all payload parsing function prototypes consistent.
1636 They all take now const unsigned char * and uint32 pair as
1637 the payload data instead of SilcBuffer. Changes all around
1638 the source tree. Other unsigned char* -> const unsigned char*
1639 changes around the tree as well.
1641 * Optimized SFTP client and server packet sending not to
1642 allocate new buffer for each packet but to recycle the
1643 first allocated buffer. Affected files are
1644 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1646 * Optimized the SFTP client to use SilcList instead of
1647 SilcDList for requests, because it is faster. Affected file
1648 is lib/silcsftp/sftp_client.c.
1650 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1651 into lib/silccore/silcid.[ch].
1653 Renamed silcpayload.[ch] into silcargument.[ch].
1655 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * If client entry is deleted with active key agreement
1658 session, abort the session.
1660 The silc_client_abort_key_agreement now calls the completion
1661 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1663 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1666 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Don't use __restrict in older GCC's. Affected file is
1669 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1671 * silc_net_localhost now attempts to reverse lookup the
1672 IP/hostname. Affected file lib/silcutil/silcnet.c.
1674 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1675 command. It can be used to gain founder privileges at
1676 the same time when joining the channel.
1678 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1679 kicker's client ID as well. Updated protocol specs.
1681 Defined that the server must send SILC_COMMAND_IDENTIFY
1682 command reply with error status to client who sent
1683 private message with invalid client ID.
1685 Updated the protocol specification.
1687 * Added silc_server_send_command_reply to send any
1688 command reply. Affected file silcd/packet_send.[ch].
1690 * Added silc_id_payload_encode_data to encode ID payload
1691 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1693 * The server now send IDENTIFY command reply with error
1694 status if client ID in private message is invalid. Affected
1695 file silcd/packet_receive.c.
1697 * Save the server key file with server's IP address in
1698 the filename instead of hostname. The affected file is
1699 irssi/src/silc/core/client_ops.c.
1701 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1706 * Added libtool support for compiling shared objects in
1707 lib/silcsim. Affected file configure.in.pre and
1708 lib/silcsim/Makefile.am. Original patch by cras.
1710 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Pid file configuration, and server's config file fixes
1713 patch by toma. Updated CREDITS file.
1715 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1717 * Fixed silc_client_channel_message to not try to decrypt
1718 the message twice if it resolved the destination client
1719 information. This could cause of dropping one channel
1720 message. Affected file lib/silcclient/client_channel.c.
1722 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1725 lib/silcclient/client.c. This function is used when the SILC
1726 Client is run under some other scheduler, or event loop or
1727 main loop. On GUI applications, for example this may be
1728 desired to used to run the client under the GUI application's
1729 main loop. Typically the GUI application would register an
1730 idle task that calls this function multiple times in a second
1731 to quickly process the SILC specific data.
1733 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1735 * Fixed silc_server_drop() for dropping the supplementary
1736 groups as well, this could cause a security hole on some
1739 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1744 * Write PID file after dropping privileges. Added -F option
1745 to run server on foreground. A patch by debolaz.
1746 Affected files silcd/server.c, silcd/silcd.c.
1748 * Fixed MOTD to return the MOTD file server name. Affected
1749 file silcd/command.c.
1751 * Added INFO command reply handling to the Irssi SILC Client.
1752 Affected file irssi/src/silc/core/client_ops.c.
1754 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Fixed the silc_idcache_list_* routines to really support
1757 the dynamic list. Fixes a crash. Affected file is
1758 lib/silccore/silcidcache.c.
1760 * Fixed the LIST command reply to really call LIST command's
1761 pending callbacks. Affected file silcd/command_reply.c.
1763 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Update conn->local_entry->nickname after giving NICK
1766 command. Affected file lib/silcclient/command.c.
1768 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1770 * Added the [pid] option to the silcd configuration file
1772 Affected files: serverconfig.[ch] and silcd.c
1774 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Save fingerprint in WHOIS command reply in server.
1777 Affected file silcd/command_reply.c.
1779 * Fixed NICK commands pending callback registration.
1780 Affected file lib/silcclient/command.c.
1782 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Use ++server->cmd_ident when sending commands in server,
1785 instead of random number. Affected file silcd/command.c.
1787 * Fixed GETKEY command reply to call actually GETKEY pending
1788 command callbacks. Affected file silcd/command_reply.c.
1790 * A bit stricter check for nicknames. Check for same nickname
1791 in NICK command also. Affected file silcd/command.c.
1793 * Do not call INFO command everytime client ID changes, only
1794 during first connecting. Affected file lib/silcclient/client.c.
1796 * Set the new nickname only after successful command reply for
1797 NICK command is returned by server. Affected file
1798 lib/silcclient/command.c.
1800 * Remove nicknames from nicklist during server_signoff notify.
1801 Should fix /NAMES bit more. The affected file is
1802 irssi/src/silc/core/silc-channels.c.
1804 * Added `fingerprint' field to the SilcIDListData in the
1805 silcd/idlist.h to hold the fingerprint of the client's
1808 Send the fingerprint of the client's public key in WHOIS
1811 Affected files silcd/command.c, and silcd/idlist.[ch].
1813 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1814 create fingerprint from given data.
1816 * Show the fingerprint of the client's public key in WHOIS.
1817 Affected files irssi/src/module-formats.[ch] and
1818 irssi/src/silc/core/client_ops.c.
1820 * Format the multiple same nicknames also during JOIN and
1821 NICK_CHANGE notifys. Affected file is
1822 lib/silcclient/client_notify.c.
1824 * Do not print error on screen for invalid private message
1825 payload since it can come if someone is sending private
1826 messages with wrong key. Affected file
1827 lib/silccore/silcprivate.c.
1829 * Fixed multiple concurrent /PING crash. Affected file
1830 lib/silcclient/command.c.
1832 * Changed the wrong ID encoding. All IP addresses must be
1833 in MSB first order in encoded format. They were encoded
1834 wrong and was in LSB format. Affected files are
1835 silcd/serverid.c, lib/silcutil/silcutil.c.
1837 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1839 * Call the `connect' client operation through the scheduler
1840 in case of error. Affected file lib/silcclient/client.c.
1842 * Call the `failure' client operation even if the error
1843 occurred locally during a protocol. Affected file is
1844 lib/silcclient/protocol.c.
1846 * Added support of sending LIST command to router from normal
1847 server. This way normal server can get list of all channels
1848 in the network too. Fixed the channel list sending in the
1849 server too. Affected files are silcd/command.c, and
1850 silcd/command_reply.[ch].
1852 * Added silc_server_update_channels_by_server and
1853 silc_server_remove_channels_by_server. They are used during
1854 disconnection of primary router and in backup router protocol.
1855 Affected file silcd/server_util.[ch], silcd/server.c and
1856 silcd/server_backup.c.
1858 * Fixed channel adding to global list in IDENTIFY command
1859 reply in server. Affected file silcd/command_reply.c.
1861 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * If the incoming packet type is REKEY or REKEY_DONE process
1864 that packet always synchronously. Fixes yet another MAC
1865 failed error on slow (dialup) connections. Affected file
1866 lib/silcclient/client.c and silcd/server.c.
1868 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * Call check_version SKE callback for initiator too. Affected
1871 file lib/silcske/silcske.c.
1873 * Implemented fix for security hole found in the SKE that was
1874 fixed in the specification few days back; the initiator's
1875 public key is now added to the HASH value computation.
1876 Added backwards support for the old way of doing it too, for
1877 old clients and old servers. Affected file is
1878 lib/silcske/silcske.c.
1880 * Enabled mutual authentication by default in SKE. If initiator
1881 is not providing mutual authentication the responder will
1882 force it. This will provide the proof of posession of the
1883 private key for responder. The affected files are
1884 lib/silcclient/protocol.c and silcd/protocol.c.
1886 * Do not cache anymore the server's public key during SKE.
1887 We do mutual authentication so the proof of posession of
1888 private key is done, and if the server is authenticated in
1889 conn auth protocol with public key we must have the public
1890 key already. Affected file silcd/protocol.c.
1892 * Added new global debug variable: silc_debug_hexdump. If
1893 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1894 file lib/silcutil/silclog.[ch].
1896 * Fixed compilation warning due to char * -> const char *.
1897 Affected files lib/silcutil/silcnet.h, and
1898 lib/silccore/silcauth.[ch].
1900 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * Fixed CMODE command when new channel key was created. If
1903 the creation failed the old key was removed. Next time giving
1904 same command would crash the server since the old key was
1905 freed already. Affected file silcd/command.c.
1907 * Fixed the silc_server_announce_get_channels to not crash
1908 on reconnect. Affected file silcd/server.c.
1910 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Added silc_log_set_debug_string function to set a regex
1913 string to match for debug output. Only the function names,
1914 or filenames matching the given debug string is actually
1915 printed. This way it is possible to filter out those debug
1916 strings that user is not interested in.
1918 Fixed a bug in silc_string_regexify.
1920 Affected files lib/silcutil/silclog.[ch], and
1921 lib/silcutil/unix/silcunixutil.c.
1923 * Changed the -d options in both server and Irssi SILC client
1924 to take the debug string as argument. Affected files
1925 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1927 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Added silc_hash_babbleprint to create a Bubble Babble
1930 Encoded fingerprint. The encoding is developed by Antti
1931 Huima (draft-huima-babble-01.txt), and it creates human
1932 readable strings out of binary data. Affected file
1933 lib/silccrypt/silchash.[ch].
1935 * Print the babble print now in addition of fingerprint as well
1936 in Irssi SILC client. Affected files are
1937 irssi/src/fe-common/silc/module-formats.[ch],
1938 irssi/src/fe-common/silc/core/client_ops.c.
1940 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Fixed a security problem found in SKE. The initiator's
1943 public key too is now added to the HASH hash value creation
1944 which is signed by the responder to create the SIGN value.
1945 This will prevent anyone in the middle to lie to the responder
1946 about the initiator's public key. If this is done now, the
1947 man in the middle will get caught. Updated the protocol
1950 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * Better installation directory handling. Configure module
1953 paths and other paths automatically to example_silc* files
1954 in doc/. A patch by toma.
1956 * Fixed compiler warning from MPI library, and from SILC RNG.
1959 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1960 It can be configured with ./configure. A patch by toma.
1962 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Find correct make to use in prepare-clean. A patch by
1965 toma. Affected file prepare-clean.
1967 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1969 * Added irssi variables use_auto_addr, auto_bind_ip,
1970 auto_bind_port and auto_public_ip.
1972 * Changed the interface for silc_client_send_key_agreement
1973 in lib/silcclient/silcapi.h
1977 irssi/src/silc/core/silc-core.c
1979 lib/silcclient/silcapi.h
1980 irssi/src/silc/core/silc-channels.c
1981 lib/silcclient/client_keyagr.c
1984 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Added silc_pkcs_public_key_compare to compare two
1987 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1989 * Check that the client who set the founder mode on the
1990 channel is the same client that is giving the founder
1991 mode to itself. It is done by comparing the saved public
1992 key (it is saved even in the authentication is passphrase).
1993 Affected file silcd/command.c.
1995 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Do not process packet for disconnected socket connection.
1998 Affected file lib/silccore/silcpacket.c.
2000 * Process the DISCONNECT packet through scheduler in the
2001 client library. Affected file lib/silcclient/client.c.
2003 * Fixed the silc_client_packet_parse to not to increase
2004 the packet sequence number if the conn->sock and the
2005 current socket connection is not same. This can happen
2006 for example during key agreement when the conn includes
2007 multiple socket connections (listeners). Affected file
2008 lib/silcclient/client.c.
2010 * The sender of the file transfer request now provides also
2011 the pointer (listener) for the key exchange protocol. If
2012 the listener cannot be created then it sends empty key
2013 agreement and lets the receiver provide the listener.
2015 Added `local_ip' and `local_port' arguments to the
2016 silc_client_file_send. If they are provided they are used,
2017 if not then it will attempt to find local IP address, if
2018 not found or bind fails then the remote client will provide
2021 Affected files are lib/silcclient/client_ftp.c and
2022 lib/silcclient/silcapi.h.
2024 * Extended the FILE SEND command to support defining the
2025 local IP and port for key exchange listener. They are
2026 optional. Affected file irssi/src/silc/core/silc-servers.c.
2028 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2030 * Defined to WHOIS command reply the sending of fingerprint
2031 of the client's public key (if the proof of posession of the
2032 corresponding private key is verified by the server).
2033 Updated to the protocol specification.
2035 * Added support of receiving the client's public key's
2036 fingerprint in command reply in client library. Affected
2037 file is lib/silcclient/command_reply.c, and
2038 lib/silcclient/idlist.[ch].
2040 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * Do not send over 128 chars long nickname to the server
2043 in NICK command. Affected file lib/silcclient/command.c.
2045 * Do not send over 256 chars long channel names to the server
2046 in JOIN command. Affected file lib/silcclient/command.c.
2048 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Assure that silc_server_close_connection cannot be called
2051 twice for same socket context. Affected file is
2054 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Send error message to application if opening file for
2057 writing during file transfer fails. Affected file is
2058 lib/silcclient/client_ftp.c.
2060 Remove all file transfer sessions for a client that we're
2061 removing from ID cache.
2063 Affected file is lib/silcclient/client_ftp.c.
2065 * Fixed silc_net_addr2bin to return correct address. Affected
2066 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2068 * Fixed file transfer session removing on signoff notify.
2069 Affected file irssi/src/silc/core/silc-servers.c.
2071 * Added the SilcClientFileError to be returned in the monitor
2072 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2073 Affected file lib/silcclient/silcapi.h.
2075 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Fixed a crash in silc_client_ftp_free_sessions and
2078 silc_client_ftp_session_free_client. Affected file
2079 lib/silcclient/client_ftp.c.
2081 * Added `disabled' field in the SilcChannelEntry in the server
2082 to indicate if the server entry is disabled. Affected file
2083 silcd/idlist.h, silcd/command[_reply].c.
2085 * SILC server adds now /var/run/silcd.pid everytime it is
2086 started. Affected file silcd/silcd.c.
2088 * Added silc_server_packet_send_clients to send a packet to
2089 the provided table of client entries. Affected file
2090 silcd/packet_send.[ch].
2092 * Fixed a crash in client resolving in client_prvmsg.c in
2093 client library. Affected file lib/silcclient/client_prvmsg.c.
2095 * Do not actually remove the client directly from ID cache
2096 during SERVER_SIGNOFF, but invalidate it. This way we
2097 preserve the WHOWAS info for the client. Affected file
2098 silcd/server_util.c.
2100 * Fixed SERVER_SIGNOFF notify handling in the server. The
2101 server is now able to process incoming SERVER_SIGNOFF notify
2102 for a server that it doesn't even know about. It will remove
2103 the clients provided in the notify. Affected file
2104 silcd/packet_receive.c.
2106 * Check for partial packet in data queue after every packet that
2107 was found from the queue. Return and wait for more data if
2108 there is partial data in queue. Affected file is
2109 lib/silccore/silcpacket.c.
2111 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2114 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2115 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2116 Affected files lib/silcclient/silcapi.h and
2117 lib/silcclient/client_ftp.c.
2119 * Check that newsize in silc_buffer_realloc is larger than
2120 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2122 * Added better monitor of file transfers. It now monitors
2123 key agreement protocol during the file transfer too. Added
2124 error reporting too. Affected files
2125 irssi/src/silc/core/silc-servers.c,
2126 irssi/src/fe-common/silc/module-formats.[ch].
2128 * Wrote a help file for FILE command.
2130 * Added silc_rng_global_get_byte_fast to get not-so-secure
2131 random data as fast as possible. Random data is read from
2132 /dev/urandom if available and from the SILC RNG if not
2133 available. It is used in padding generation. Affected file
2134 lib/silccrypt/silcrng.[ch].
2136 * All packets in client library are now processed synchronously.
2137 Optimized packet processing a lot. Affected file
2138 lib/silcclient/client.c.
2140 * All server connection packets are processing synchronously
2141 now in server, to optimize packet processing. Affected file

2145 if make install is given. Affected files: all Makefile.am's.
2147 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Assure that silc_client_notify_by_server_resolve does not
2150 resolve the client information multiple times. If it cannot
2151 be found by the first it cannot be found at all. Affected
2152 file lib/silcclient/client_notify.c.
2154 * Fixed WHOWAS command reply calling. Affected file
2155 lib/silcclient/command_reply.c.
2157 * Removed all references to silc_idlist_get_client from the
2158 Irssi SILC client since that call is internal call used by
2159 the library. The Irssi SILC client will use now client
2160 retrieval functions found in silcapi.h.
2162 * Fixed a bug in resolving nickname info before sending
2163 private message. It used freed memory. Affected file
2164 irssi/src/silc/core/silc-servers.c.
2166 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Assure my_channels statistics cannot go negative in server.
2169 Affected files silcd/server.c, silcd/server_util.c.
2171 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2185 * Added silc_net_localip to return local host's IP address.
2186 Affected file lib/silcutil/silcnet.[ch].
2188 * If key exchange or rekey protocol is active for a connection
2189 parse all packets syncronously since there might be packets
2190 in packet queue that we are not able to process without first
2191 processing packets before them. Affected file silcd/server,
2192 lib/silcclient/client.c.
2194 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2195 whether library should continue processing the packet.
2196 Affected file lib/silccore/silcpacket.h.
2198 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2227 lib/silcutil/silcutil.[ch].
2229 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Resolve the client info when received private message or
2232 channel message for a client which nickname we don't know.
2233 Affected files lib/silcclient/client_prvmsg.c and
2234 lib/silcclient/client_channel.c.
2236 * Do not crash in /KEY if client is not connected. Affected
2237 file irssi/src/silc/core/silc-channels.c.
2239 * Added SilcClientStatus field to the SilcClientEntry in the
2240 lib/silcclient/idlist.h.
2242 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2243 is incomplete and is being resolved, it won't be resolved
2246 Make sure also that USERS command reply does not resolve
2247 twice information. Affected file is
2248 lib/silcclient/command_reply.c.
2250 Make sure that silc_client_get_clients_by_list does not
2251 resolve twice same information.
2253 * Check for valid client->id in the silc_server_free_client_data.
2254 Affected file silcd/server.c.
2256 * Fixed /GETKEY nick@server not to crash if the server entry
2257 is not found. Affected file lib/silcclient/command.c.
2259 * Fixed the silc_server_check_cmode_rights to check the
2260 requested modes correctly. Affected file silcd/command.c.

2264 * Better checks for non-printable chars in nick added.
2265 Affected file silcd/command.c.
2267 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Call the silc_server_udpate_servers_by_server in the
2270 primary router that comes back online in the backup resuming
2271 protocol. Otherwise it routes packets wrong. Affected file
2272 silcd/server_util.[ch], silcd/server_backup.c.
2274 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2277 lib/silcutil/silcbuffmt.[ch].
2279 * Redefined the SILC packet header to include the padding
2280 length. Affected file lib/silccore/silcpacket.[ch].
2282 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2283 length for maximum padding up to 128 bytes). Affected
2284 file lib/silccore/silcpacket.h.
2286 * Removed all backwards support for old 0.5.x MAC thingies.
2287 The SILC packet header change makes it impossible to be
2288 backwards compatible.
2290 * Send the ENDING packet with timeout in the backup resuming
2291 protocol. This is to assure that all routers has connected
2292 to the primary router. Affected file silcd/server_backup.c.
2294 * Changed the RNG to take the first IV from random data. It
2295 used to take it from zero actually. Changed the RNG also
2296 to use /dev/urandom during session. /dev/random is used
2297 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2299 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Changed the SILC packet header to have the first two bytes
2302 (the packet length) encrypted. Affected files aroung the
2303 code tree, lib/silccore/silcpacket.[ch]. Removed the
2304 SilcPacketCheckDecrypt callback. It is not needed anymore
2305 since the silc_packet_receive_process will determine now
2306 whether the packet is normal or special.
2308 * Implemented the unidirectional MAC keys. Affected files
2309 lib/silcske/silcske.c, silcd/protocol.c and
2310 lib/silcclient/protocol.c.
2312 * Implemented the packet sequence number to the MAC computation.
2313 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2314 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2315 lib/silcclient/protocol.c.
2317 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * Allow backup router to announce servers. All servers
2320 announced by backup router are added to the global list
2321 automatically. Update hte server's socket to our primary
2322 router also when backup router announces a server.
2323 Affected file silcd/packet_receive.c.
2325 * Do not update the client->router in the function
2326 silc_server_udpate_clients_by_server if the client is on
2327 global list. We might fail to find any specific server
2328 for locally connected clients and local cell clients. They
2329 should still use the `from' and not `to' as client->router.
2330 This fixes backup router resuming protocol. Affected file
2331 silcd/server_util.c.
2333 * Decrease channel statistics count only if the channel
2334 deletion worked. Affected files are silcd/server.c and
2335 silcd/server_util.c.
2337 * Added silc_server_update_servers_by_server to update origin
2338 of all server entries. Used during backup router protocol.
2339 Affected files silcd/server_util.[ch], silcd/server.c. and
2340 silcd/backup_router.c.
2342 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2343 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2344 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2345 lib/silccrypt/silchmac.c.
2347 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Assure that router cannot reroute the same channel message
2350 to the sender. Affected file silcd/packet_receive.c.
2352 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Made better checks that the channel message is not sent
2355 to the router it came from. Affected file is
2356 silcd/packet_send.c. Fixed memory leak too.
2358 * Announce informations for incoming router connection, but
2359 only after checking if it is replaced by backup router.
2360 Affected file silcd/packet_receive.c.
2362 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Fixed the backup resuming protocol to work in multiple
2365 router environment. Affected file silcd/server_backup.c.
2367 * Route packet only to one router in the function
2368 silc_server_packet_send_to_channel. Affected file is
2369 silcd/packet_send.c.
2371 * Fixed silc_server_send_notify_dest to set the broadcast
2372 flag. Fixed the silc_server_send_notify_topic to actually
2373 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2374 Affected file silcd/packet_send.c.
2376 * Changed the SFTP Filesystem interface. Changed the
2377 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2378 the filesystem operation function. The SilcSFTPFilesystem
2379 is now a context that is allocated by all filesystem allocation
2380 functions and it already includes the operations structure
2381 and filesystem specific context. It is given as argument
2382 now to the silc_sftp_server_start. This made the interface
2383 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2384 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2386 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Changed the backup router adding and getting interfaces
2389 in the server. The router that will be replaced by the
2390 specified backup router is now sent as argument. Affected
2391 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2394 * Added silc_net_addr2bin_ne to return the binary form of
2395 the IP address in network byte order. Affected files
2396 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2398 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Check for existing server ID in silc_server_new_server
2401 and in silc_server_connect_to_router_final and remove the
2402 old entry if it exists. Affected file silcd/packet_receive.c,
2405 * Send the channel message always to only one router, either
2406 in upstream or downstream. Affected file is
2407 silcd/packet_send.c.
2409 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Wrote the definition of the backup resuming protocol to the
2412 protocol specification.
2414 * Removed one redundant channel key generation from normal
2415 server during joining procedure. Removed one redundant
2416 channel key sending from server to router during joining
2417 procedure. Affected file silcd/command.c.
2419 * Made minor bugfixes to the backup router resuming protocol.
2420 Affected file silcd/server_backup.c, server.c.

2425 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2428 * Implemented the backup resuming protocol that is used to
2429 resume the primary router position in the cell after the
2430 primary router comes back online. Affected files
2431 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2432 and silcd/server_util.[ch].
2434 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Sleep two (2) seconds after sending QUIT command to server.
2437 Affected file lib/silcclient/command.c.
2439 * Assure that if outgoing data buffer is pending do not force
2440 send any data. Affected file silcd/packet_send.c.
2442 * Assure that if outgoing data buffer is pending do not force
2443 send any data. Affected file lib/silcclient/client.c.
2445 * Implemented the backup router support when the primary router
2446 goes down. The servers and routers can now use the backup
2447 router as new primary router without loosing connectivity.
2449 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2452 in the server to indicate disabled entry. All data read
2453 from the connection will be ignored and no data is sent
2454 for entry that is disabled. Affected files are
2455 silcd/idlist.h, silcd/server.c.
2457 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Created SFTP client and server test programs in the
2460 lib/silcsftp/tests directory.
2462 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Implemented memory filesystem (virtual filesystem) for
2465 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2468 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Implemented the SFTP (SSH File Transfer Protocol) to the
2471 lib/silcsftp. It includes SFTP client and SFTP server
2474 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Moved lib/silccore/silcprotocol.[ch] to the
2477 lib/silcutil library.
2479 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2480 take variable argument list pointer as argument. Affected
2481 file lib/silcutil/silcbuffmt.[ch].
2483 * Added silc_buffer_set function that is used to set data
2484 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2485 Affected file lib/silcutil/silcbuffer.h.
2487 * Changed various routines in the core library to use the new
2488 silc_buffer_set instead of allocating new buffer only for
2491 * Added 64-bit value formatting and unformatting support to the
2492 silc_buffer_[un]format routines. Affected file is
2493 lib/silcutil/silcbuffmt.[ch].
2495 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2496 to includes/bitmove.h.
2498 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Fixed channel user mode saving in client library. Affected
2501 file lib/silcclient/command[_reply].c.
2503 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Defined the file transfer to the SILC Protocol. Added
2506 new packet type SILC_PACKET_FTP and defined File Transfer
2507 Payload. The mandatory file transfer protocol is SFTP
2508 (SSH File Transfer Protocol). Affected file in addition
2509 of the internet draft is lib/silccore/silcpacket.h.
2511 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2512 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2513 is used as part of backup router protocol when the primary
2514 router of the cell is back online and wishes to resume
2515 the position as primary router.
2517 * Redefined the MAC generation keys in the protocol. The
2518 same key is not used anymore in both direction. Both
2519 direction will now use different keys for sending and
2520 receiving. This fixes a potential security flaw. This
2521 change causes incompatibilities in the protocol.
2523 * Redefined also the MAC computation from the packet.
2524 An packet sequence number is now added to the MAC
2525 computation. This prevents possible replay attacks against
2526 the protocol. This change too causes incompatibilities
2529 Added `sequence' field to the SilcPacketContext to hold
2530 the current sequence number for the packet.
2532 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Added `created' field to the SilcIDListData in the file
2535 silcd/idlist.h to indicate the time when the entry was
2538 * Added `created' field to the SilcChannelEntry too. Affected
2539 file silcd/idlist.h.
2541 * Added `creation_time' aguments to all the announcement functions
2542 in the server. If it is provided then only the entries that
2543 was created after the provided time frame are actually
2544 announced. Affected file silcd/server.[ch].
2546 * The protocol says that the Channel ID's IP address must be
2547 based on the router's IP address. Added check for this in
2548 the silc_server_new_channel when processing incoming New Channel
2549 Payload. Affected file silcd/packet_receive.c.
2551 * Print out the correct version with --version in SILC client.
2552 Affected file irssi/src/silc/core/silc-core.c.
2554 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Fixed WHOWAS command to check for completnes of the client
2557 entry always, not just when the command is coming from client.
2558 Affected file silcd/command.c.
2560 * Added new function silc_server_packet_queue_purge to purge the
2561 outgoing data queue to the network. After the function returns
2562 it is guaranteed that the outgoing packet queue is empty.
2563 Affected file silcd/packet_send.[ch].
2565 * Purge the outgoing packet queue in the rekey protocol's final
2566 callback to assure that all rekey packets go to the network
2567 before quitting the protocol. Affected file silcd/server.c.
2569 * Added silc_client_packet_queue_parse as similar function as
2570 in server to the client library. The affected file is
2571 lib/silcclient/client.c.
2573 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Splitted silcd/server.c and created silcd/server_util.[ch]
2576 for utility functions.
2578 * Added new socket flag SILC_SF_DISABLED to indicate that the
2579 connection is open but nothing can be sent to or received from
2580 the connection. Affected file lib/silcutil/silsockconn.[ch].
2581 The checking for disabled socket is checked in the low level
2582 silc_socket_write and silc_socket_read functions.
2584 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Allow only nicknames and channel names that fits into the
2587 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2589 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * When processing JOIN command reply in server check that if
2592 the channel exists in our global list we'll move it the local
2593 list. Affected file silcd/command_reply.c.
2595 * Fixed the check whether client is joined on the channel already
2596 in JOIN command. Affected file lib/silcclient/command.c.
2598 * Fixed the JOIN command reply to check whether the channel
2599 already exists. Affected file lib/silcclient/command_reply.c.
2601 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * Added silc_ske_status_string to map the SKE error numbers
2604 to readable strings. The affected files are
2605 lib/silcske/silcske[_status].[ch].
2607 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Do not show the private channels on the WHOIS channel list
2610 as it is not allowed by the protocol. The affected file is
2613 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Assure that the packet length digged from the actual packet
2616 is something sensible in the silc_packet_decrypt_rest_special
2617 in lib/silccrypt/silcpacket.c.
2619 * Free and NULL the allocated pointer in silc_hmac_alloc if
2620 the HMAC allocation fails. The affected file is
2621 lib/silccrypt/silchmac.c.
2623 * Print the selected security properties to the log files in
2624 the server. Affected file silcd/protocol.c.
2626 * Add SKE's reference counter even if calling the completion
2627 callback manually. Otherwise it goes negative, although it
2628 does not cause any problems. The affected file is
2629 lib/silcske/silcske.c.
2631 * Remove the client entry with short timeout after giving the
2632 KILL command. Affected file lib/silcclient/command.c.
2634 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2635 case all found clients are already disconnected (WHOWAS would
2636 found them) in the server. Affected file silcd/command.c.
2638 * Update the last_receive (time of last data received) to be
2639 updated only when received private or channel message so that
2640 the idle time showed in WHOIS makes more sense.
2642 * Added boolean field `valid' in to the SilcClientEntry in the
2643 client library to indicate whether the entry is valid or not.
2644 This fixes the nickname change bug on channel when changing
2645 the nickname to be same than the old (like nick to Nick) the
2646 nickname formatter doesn't set the new nick anymore to Nick@host.
2647 Affected file lib/silcclient/idlist.[ch].
2649 * Now actually fixed the nickname changing on disconnection.
2650 Added new function silc_change_nick to the Irssi SILC Client.
2651 Affected file irssi/src/silc/core/client_ops.c,
2652 irssi/src/silc/core/silc-nicklist.[ch].
2654 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Check that the public key exists in the GETKEY command before
2657 trying to encode it. Affected file silcd/command.c.
2659 * Print some notifications on received public keys with GETKEY
2660 command in the Irssi SILC Client. Affected files are
2661 irssi/src/fe-common/silc/module-formats.[ch],
2662 irssi/src/silc/core/client_ops.c.
2664 * Use IDENTIFY command to resolve the server information in the
2665 GETKEY command instead of INFO command. Affected file
2666 lib/silcclient/command.c.
2668 * All command reply functions in the client library now calls
2669 the pending command reply callbacks even if an error has
2670 occurred. The server has done this a long time and now it was
2671 time to move the client library to this as well. Now all
2672 errors can be delivered back to the pending command reply
2673 callbacks if necessary. Affected files are
2674 lib/silcclient/command[_reply].[ch].
2676 * Change the nickname on disconnection back to the username
2677 because in reconnect the server will enforce it to it anyway.
2678 Affected file irssi/src/silc/core/silc-servers.c.
2680 * Fixed a config file parsing bug in the Irssi SILC client.
2681 Affected file irssi/src/silc/core/clientconfig.c.
2683 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * When printing the channel mode on JOIN, verify that the
2686 channel key and channel's HMAC are valid. Affected file
2687 irssi/src/silc/core/client_ops.c.
2689 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2692 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2693 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2695 * Removed channel key rekey task deleting from the function
2696 silc_server_save_channel_key. Affected file silcd/server.c.
2697 Added explicit timeout task context instead that is used to
2698 delete the task if we are registering a new task before the
2699 new task has elapsed.
2701 * When channel key rekey occurs the client library now saves
2702 the old channel key for a short period of time (10 seconds) and
2703 is able to use it in case some is still sending channel
2704 messages encrypted with the old key after the rekey. Affected
2705 file lib/silcclient/[idlist.h|client_channel.c].
2707 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Added check to the silc_server_new_id_real to not accept
2710 new ID if it is the sender's own ID. Affected file is
2711 silcd/packet_receive.c.
2713 * Assure that we do not announce ourself or the one we've
2714 sending our announcements when we're router and are announcing
2715 servers to our primary router. Affected file silcd/server.c.
2717 * Fixed silc_server_command_identify_check_client to assemble
2718 correct WHOIS packet. It send corrupted WHOIS packet and
2719 caused problem with router to router connections. Affected
2720 file silcd/command.c.
2722 Fixed also silc_server_command_whois_check the same way
2723 as for the IDENTIFY command.
2725 * Added new SilcIDListStatus to the server in the SilcIDListData
2726 structure. The status now includes the current status of
2727 the entry (like registered, resolved etc.). Affected file
2728 silcd/idlist.[ch]. Defined a bunch of different status types
2729 as well. This replaced the old boolean registered field as well.
2731 Added resolve_cmd_ident field to the SilcClientEntry structure
2732 too so that if the entry is for example being resolved so
2733 another command may attach to the same pending command reply
2734 without requiring to resolve the same entry again. This concept
2735 should optimize the WHOIS and the IDENTIFY resolving under
2736 heavy load by taking away unnecessary resolving for entries
2737 that are being resolved already.
2739 Added support for adding multiple pending commands for one
2740 command idenfier. Affected file silcd/command[_reply].[ch].
2742 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2743 before deleting the data. Otherwise the hash table will have
2744 freed data in comparison functions. Affected file is
2745 silcd/command_reply.c.
2747 * Fixed silc_idlist_replace_client_id to add the new entry to
2748 the cache with NULL nickname. Otherwise there will be invalid
2749 memory as the nickname after the nickname is freed. Affected
2750 file silcd/packet_receive.c.
2752 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2753 saved into wrong slots because the previous number of entries
2754 was not taken into account. Affected file silcd/idlist.c.
2755 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2757 * If we are router and we receive JOIN notify to a channel that
2758 does not have any users then notified client is marked as the
2759 channel founder, as it is it. The affected file is
2760 silcd/packet_receive.c
2762 * Added to the extended hash table API's table_del_*ext functions
2763 the destructor as argument too, so that the caller can decide
2764 which destructor to use or whether to use destructor at all.
2765 Affected file lib/silcutil/silchashtable.[ch].
2767 * Fixed ID Cache purging. It actually deleted the entries from
2768 the hash table after the data was freed. The hash table ended
2769 up comparing freed memory. The affected file is
2770 lib/silccore/silcidcache.c.
2772 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Fixed Irssi SILC client's KILL command's HELP syntax.
2776 * The USERS command now resolves the detailed user information
2777 if the userinfo field is missing. Affected file is
2778 lib/silcclient/command_reply.c.
2780 * Do not print error in silc_file_read if the read file does
2781 not exist. Just silently return NULL. Affected file is
2782 lib/silcutil/silcutil.c.
2784 * Fixed the silc_log_output to not wine about NULL filename
2785 and to not create some bogus " " filename. Affected file is
2786 lib/silcutil/silclog.c.
2788 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2790 * Fixed various printing bugs on the user interface in the
2791 Irssi SILC Client. Minor changes that were forgotten from
2794 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2796 * Fixed the configure.in.pre and the compilation and distribution
2797 environment to support the new autoconf 2.52. That version is
2798 now required to compile the CVS trunk.
2800 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2803 to generally parse user@fqdn format strings. Affected file
2804 lib/silcutil/silcutil.c.
2806 * Added nickname_format and nickname_force_format fields to the
2807 SilcClientParams structure. The first one defines the format
2808 for the nicknames that the library will enforce if the receives
2809 multiple same nicknames. The second one is boolean value and
2810 can be used to force the library to always enforce the format
2811 to the nicknames regardles whether there are multiple nicknames
2812 or not. This configurable formatting was employed to flexibly
2813 support accessing multiple nicknames from the user interface.
2814 The userinterface can now set the nicknames to what ever format
2815 they prefer. Affected file lib/silcclient/silcapi.h.
2817 Added function silc_client_nickname_format to the file
2818 lib/silcclient/idlist.c. It performs the nickname formatting.
2820 Added new field `hostname´ to the SilcClientEntry context.
2821 It holds the hostname of the client. Affected file is
2822 lib/silcclient/idlist.h.
2824 * Irssi SILC Client sets the nicknames in nick@hostn format.
2825 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2826 irssi/src/silc/core/silc-core.c.
2828 The WHOIS printing now also shows both the real nickname and
2829 the formatted nickname so that user knows how to access the
2830 user if there are multiple same nicknames cached. Affected
2831 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2832 printing formatting too to take the hostname now as a separate
2833 argument. The Affected file is
2834 irssi/src/fe-common/silc/modules-formats.[ch].
2836 * Changed the silc_client_get_clients_local to accept the formatted
2837 nickname as argument. It accepts the real nickname too but the
2838 formatted nickname can be used to find the true entry from
2839 multiple entries. Affected file lib/silcclient/silcapi.h and
2840 lib/silcclient/idlist.c.
2842 * Added nickname_format_parse field to the SilcClientParams.
2843 It is a callback function provided by the application to parse
2844 the nickname out of the formatted nickname string. The library
2845 calls it to get the nickname from the formatted string. Since
2846 the application generally knows better the format of the nickname
2847 string it parses it instead of the library, even though library
2848 encodes the formatted string. If the callback function is not
2849 provided then the library will use the string as is. The
2850 affected file is lib/silcclient/silcapi.h.
2852 * All the nickname strings passed to the client library in
2853 commands are now expected to be formatted nickname strings.
2854 If the command does not support the formatted nickname string
2855 it will assume that the sent string is the actual nickname.
2856 Affected file lib/silcclient/command.c.
2858 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Added public key authentication support to OPER and SILCOPER
2861 commands in the client library. Affected file is
2862 lib/silcclient/command.c.
2864 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Changed the get_auth_methdod client operation to be asynchronous.
2867 It can be async if the application resolves the authentication
2868 method from the server during the negotiation. Added new
2869 SilcGetAuthMeth completion callback that the application will
2870 call after resolving the authentication method.
2872 Added function silc_client_request_authentication_method that
2873 the application can use to resolve the authentication method
2874 from the server. Added also SilcConnectionAuthRequest callback
2875 that the library will call after the server has replied. The
2876 application can call this function if it does not know the
2877 current authentication method.
2879 Affected files are lib/silcclient/client.c and
2880 lib/silcclient/silcapi.h.
2882 * The Irssi SILC client now automatically resolves the authentication
2883 method incase any configuration information is not present (and
2884 currently there never is). The affected file is
2885 irssi/src/silc/core/client_ops.c.
2887 * Fixed public key authentication from the client library.
2888 Affected file lib/silcclient/protocol.c. Changed also the
2889 protocol specification about the public key authentication in
2890 the connection authentication protocol. The actual data to be
2891 signed is now computed with a hash function before signing.
2893 * Fixed the public key authentication from the server as well.
2894 Affected file silcd/protocol.c.
2896 * Removed the mlock()'s from the memory allocation routines.
2897 Affected file lib/silcutil/silcmemory.c. The ./configure does
2898 not check anymore for the mlock(). Affected file is
2901 * Fixed USERS command in server to allow the execution of the
2902 command for private and secret channels if the client sending
2903 the command is on the channel. Affected file silcd/command.c.
2905 * Fixed silc_client_get_clients_local to return the clients
2906 count correctly. It could return wrong value. Affected file
2907 lib/silcclient/idlist.c.
2909 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2912 types. The assembler optimizations seemed not to like 64-bit
2913 data types. The assmebler optimizations thus are now enabled
2914 also for BSD systems as opposed to only enable them for Linux.
2916 * Do not check for threads at all on BSD systems. Affected
2917 file configure.in.pre.
2919 * Removed -n and -h options from the Irssi SILC Client since
2920 they are not used in silc.
2922 * Fixed the prime generation to assure that the first digit
2923 of the generated random number is not zero since our conversion
2924 routines does not like number strings that starts with zero
2925 digit. If zero digit is seen the random number is regenerated.
2926 This caused some corrupted RSA keys when the zero first digit
2927 was met. Affected file lib/silcmath/silcprimegen.c.
2929 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Fixed WIN32 configuration in the ./configure script.
2932 Fixed to include xti.h on environments that has it.
2933 Patches by Carsten Ilchmann and andrew.
2935 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Changed the silc_id_create_client_id to be collision
2938 resistant. It is now assured that there cannot be created
2939 two same client ID's. I suspect that some weird bugs in
2940 the server were actually caused by duplicate Client IDs.
2941 Affected file silcd/serverid.[ch]. A router receiving
2942 new ID now also assures and informs the sending server
2943 if the ID caused collision.
2945 * Changed the silc_id_create_channel_id to also assure that
2946 there are no collisions.
2948 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Statement about ignoring the Mutual Authentication flag when
2951 performing rekey with PFS was a bit misleading. It is ignored
2952 if it was set in the initial negotiation, it cannot be even
2953 set in the rekey. Fixed in the ke-auth draft. Started the
2954 new versions of the protocol drafts in the doc/.
2956 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Fixed a bug in silc_client_command_identify_save when saving
2959 new channel information. The channel name was no duplicated
2960 and caused crash on exit. Affected file is
2961 lib/silcclient/command_reply.c.
2963 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Fixed the getkey command handling in the server. Send just
2966 empty OK reply to the sender if the key could not be fetched
2967 (but everything else was ok, like the key just was not available).
2968 Changed the public key parameter to optional in the protocol
2969 specs so that empty OK reply can be sent. Affected file
2972 Added a message to Irssi SILC client to tell to user if the
2973 server did not return a public key.
2975 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Fixed a channel key regeneration bug. It registered new
2978 timeout tasks exponentially until all system resources were
2979 used. Affected file silcd/server.c.
2981 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Added the SILC Document generator to the scripts/silcdoc.
2984 It can be used to generate the Toolkit Reference Manual out
2985 of the source tree. Internally it will also use the RoboDoc
2986 generator now imported in util/robodoc.
2988 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Added couple of return's in rekey protocol if error orccurred
2991 during the protocol. The execution must be terminated.
2992 Affected file silcd/protocol.c. Also, terminate the protocol
2993 always with timeout.
2995 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * The client's Client ID was created initally from the wrong
2998 nickname (it could have been in format nick@host) in the
2999 silc_server_new_client. Affected file silcd/packet_receive.c
3001 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * Added some SILC_LOG_ERROR's to various error conditions
3004 if client could not be added to ID cache. Affected files
3005 silcd/packet_receive.c and silcd/server.c.
3007 * When client's sock->user_data is freed, NULL also the
3008 client->router and client->connection pointers. Added check
3009 for these pointers being NULL to various places around the
3010 code. Affected file silcd/server.c.
3012 * Added client->data.registered == TRUE checks to various
3013 places around the code to assure that unregistered client's
3014 are not handled when it is not allowed. Affected file
3017 * Added `bool registered' fields to all
3018 silc_idlist_[server|client]_get_* routines to indicate whether
3019 the fetched client needs to be registered or not. Affected
3020 file silcd/idlist.[ch].
3022 * Add your own entry as registered to the ID cache in the
3023 server. Affected file server.c.
3025 * Fixed a bug in silc_server_new_server. The SilcServer was
3026 set as the new server's context instead of SilcServerEntry.
3027 This naturally caused some weird bugs.
3029 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Do not delete the channel rekey task when adding it
3032 for in silc_server_create_channel_key.
3034 * Changed the silc_server_create_channel_key to return
3035 TRUE or FALSE to indicate the success of the channel key
3038 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Fixed MSVC++ project files and added missing files to
3041 Makefiles under win32/.
3043 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Do not add TCP_NODELAY flag if the operating system
3046 does not have it defined. Affected files are
3047 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3049 * Fixed buffer overflow from Irssi SILC Client. Affected
3050 file irssi/src/fe-common/core/themes.c.
3052 * Fixed double free in client library in the file
3053 lib/silcclient/client.c when disconnecting from server.
3055 * Applied double free patch from cras to Irssi SILC client.
3056 Affected files irssi/src/core/[modules/expandos].c
3058 * Fixed the disconnection handling to Irssi SILC Client.
3059 The application must call silc_client_close_connection
3060 in ops->connect client operation in case of failure of
3061 the connection. Affected file is
3062 irssi/src/silc/core/client_ops.c.
3064 * Do not set sock->protocol to NULL in the function
3065 silc_client_close_connection after executing the protocol's
3066 final callback since the sock might not be valid anymore.
3067 Affected file lib/silcclient/client.c.
3069 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3071 * Do not enable SILC_THREADS if the linking with libpthread
3072 did not happen. Affected file configure.in.pre.
3074 * Added notion to protocol specification that server must
3075 verify the sent authentication payload with CMODE when
3076 setting the channel founder key. Implemented it to the
3077 server. Affected file silcd/command.c.
3079 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Added _EXTRA_DIST SILC distribution variable to the
3082 distributions file. It is used to conditionally add extra
3083 files or directories to the specific distribution. Affected
3084 files ./prepare, Makefile.am.pre and distributions.
3086 Removed the `_' from the start of the distribution names.
3089 * Added README.WIN32 for instructions to compile the Toolkit
3092 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Fixed a double free in disconnection in the server. Affected
3095 file is silcd/server.c.
3097 * Fixed the lib/silcske/groups.c to work now also with GMP
3098 MP library. The string conversion did not work when using
3099 specific base and the base is indicated in the string as well.
3101 * Created win32/ directory which now includes MSVC++ specific
3102 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3103 It will appear only in the toolkit distribution
3105 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Changed the key material distribution function in case when
3108 the hash output is too short. The data is now concatenated
3109 a bit differently than it used to. Made the change to the
3110 SKE protocol specification.
3112 * Added better GMP detection to configure.in.pre. A patch
3115 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Fixed a minor bug in SKE that might cause some problem on
3118 some platforms. Affected file lib/silcske/silcske.c.
3120 * Added the cookie checking for initiator in the SKE. It checks
3121 that the responder returns the sent cookie unmodified. The
3122 affected file is lib/silcske/silcske.c. Added new SKE
3123 error type INVALID_COOKIE that can be sent during the
3124 negotiation. Fixed some memory leaks as well.
3126 * Added the "invalid cookie" error message to Irssi SILC client's
3129 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3131 * Added `task_max' field to the SilcClientParams to indicate
3132 the maximum tasks the scheduler can handle. If set to zero,
3133 default values are used. Affected file lib/silcclient/silcapi.h.
3135 * Fixed memory leaks in silc_client_close_connection. Affected
3136 file lib/silcclient/client.c.
3138 * Added silc_client_del_client_entry to client library to free
3139 all memory of given client entry. Affected file is
3140 lib/silcclient/idlist.[ch].
3142 * Added new functions silc_client_del_channel and
3143 silc_client_del_server to delete channel and server entries.
3144 Affected file lib/silcclient/[silcapi.h/idlist.c].
3146 * Removed silc_client_del_client_by_id from silcapi.h.
3148 * Fixed the INFO command to return the server's own info
3149 correctly when querying by Server ID. Affected file is
3152 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * Removed the non-blocking settings in WIN32 code in the
3155 silc_sock_[read/write] and added SleepEx instead. Affected
3156 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3157 of input data is now checked with FIONREAD and ioctlsocket.
3159 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * Call silc_schedule_task_del_by_context in the
3162 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3163 Affected file lib/silccore/silcprotocol.c.
3165 * Call silc_protocol_cancel for active protocols in the
3166 silc_server_close_connection if the funtion
3167 silc_server_free_sock_user_data has not been called.
3168 Affected file silcd/server.c.
3170 * Generic tasks cannot be deleted using the del_by_fd
3171 task deleting function since generic tasks does not match
3172 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3174 * Added a notion to SILCOPER help file that the SILCOPER works
3175 only on router server, not on normal server.
3177 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Added for WIN32 support for the new scheduler as well.
3180 Affected file lib/silcutil/win32/silcwin32schedule.c.
3182 * Fixed the SHA1 implementation to work on various platforms.
3184 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3186 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3187 API. It is part of the scheduler now. Everything else is
3188 as previously but some functions has changed their names.
3189 Checkout the lib/silcutil/silcschedule.h for the interface.
3190 Updated all applications to use the new interface. Affected
3191 files are lib/silcutil/silcschedule.[ch].
3193 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3195 * Found a bug in the SKE implementation. The HASH value,
3196 specified by the protocol, was not computed correctly. The
3197 public key of the responder was not added to the computation
3198 even though it is mandatory. Affected file lib/silcske/silcske.c.
3199 This unfortunately causes incompatibilities with older
3200 clients and servers.
3202 * Added WIN32 specific network init and uninit functions:
3203 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3204 the Winsock2. Affected file lib/silcutil/silcnet.h and
3205 lib/silcutil/win32/silcwin32net.c.
3207 * Set the socket always to nonblocking mode on WIN32 after
3208 reading data or writing data. Affected file is
3209 lib/silcutil/win32/silcwin32sockconn.c.
3211 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3213 * Fixed various compilation problems under WIN32. Affected
3214 files lib/silcutil/win32/silcwin32thread.c and
3215 lib/silcutil/win32/silcwin32schedule.c.
3217 * Removed all _internal.h #includes from public header
3218 files. Internal headers must never be included from
3221 Removed also the lib/silcske/payload_internal.h file.
3223 * All include files that may be needed (public and some others
3224 included by the public headers) by application developers are
3225 now copied to the ./includes directory. It does not copy any
3226 internal headers. Affected file Makefile.defines.pre and all
3227 Makefile.am's under lib/ and subdirs.
3229 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Do not change the ~/.silc directory's permissions automatically.
3232 Affected file irssi/src/silc/core/clientutil.c.
3234 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Do not cancel the protocol in silc_server_close_connection
3237 it might cause recursion. Now cancelled in the function
3238 silc_server_free_sock_user_data. Affected file silcd/server.c.
3240 * Fixed the silc_server_remove_clients_by_server to regenerate
3241 the channel keys correctly finally. Added also new function
3242 silc_server_remove_clients_channels to actually do it.
3243 Affected file silcd/server.c.
3245 * Fixed the silc_server_new_channel to not crash by giving
3246 wrong router to the new channel. Affected file is
3247 silcd/packet_receive.c.
3249 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3251 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3252 which is given as argument to the silc_client_alloc now.
3253 It can be used to configure the client and set various parameters
3254 that affect the function of the client.
3256 * The USERS command in server did not check whether the channel
3257 is private or secret. Affected file silcd/command.c.
3259 * Added new argument to the USERS command in protocol specification.
3260 The USERS command now can take the channel name as argument
3261 as well. Added support for this in client and server and
3262 updated the protocol specs.
3264 * Completed the GETKEY command in client. It can be now used
3265 to fetch also servers public key not only some clients.
3266 Affected files lib/silcclient/command[_reply].c.
3268 * Added silc_client_get_server to return server entry by the
3269 server name. Affected files lib/silcclient/silcapi.h and
3272 * Redefined the IDENTIFY command in protocol specification to be
3273 more generic. It now can be used to query information about
3274 any entity in the SILC Network, including clients, servers and
3275 channels. The query may be based either the entity's name
3276 or the ID. Added support for this in both client and server.
3278 Affected files silcd/command.c and lib/silcclient/command.c
3279 and command_reply.c.
3281 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3282 the _from_client and _from_server functions. Affected file
3285 * Added silc_client_get_channel_by_id_resolve to the file
3286 lib/silcclient/silcapi.h to resolve channel information by
3287 its ID. Added also silc_client_get_channel_by_id that
3288 does not resolve it from the server.
3290 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3292 * Added SilcServerEntry context into the client library
3293 to represent one server. The INFO command now allocates
3294 these to save the resolved server info. For now on the
3295 client library will also keep information about servers,
3296 connected and resolved with INFO.
3298 The INFO command now allocates the SilcServerEntry context
3299 and saves the server info there. The COMMAND_REPLY in
3300 the INFO now returns the parameters to application in
3301 same order as defined in the protocol specification.
3303 The entries are cached in the client->server_cache.
3305 * The INFO command is now issued after received the Client ID
3306 from the server. Affected file lib/silcclient/client.c.
3308 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3309 to the application as the mode changer might be server.
3310 It is guaranteed that NULL is not returned anymore to the
3311 application. Affected file lib/silcclient/client_notify.c.
3313 The ID Type is now also passed to the application so that
3314 it can check whether the returned entry is SilcClientEntry
3317 Added new function silc_client_get_server_by_id to return
3318 the server entry by ID. Affected files are the
3319 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3321 * Do not create the channel in the Irssi SILC Client when issuing
3322 the JOIN command but when received the sucessful JOIN command
3323 reply. Otherwise the channel might get created even though we
3324 could not join it. The Affected file is
3325 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3327 * Fixed a channel joining bug in router. The router must also
3328 check the channel modes, invite and ban lists etc. when serving
3329 the JOIN command sent by normal server. Affected file is
3330 silcd/command.c. The router now resolves the client's
3331 information from the server who sent the JOIN command if it
3332 does not know it, and processes the JOIN command only after
3335 * Changed the SilcCommandCb to take new argument; void *context2.
3336 Affected file lib/silccore/silccommand.h
3338 The second argument in the command callbacks in the server now
3339 includes the SilcServerCommandReplyContext if the command was
3340 called as pending command callback from the command reply.
3341 Otherwise it is NULL. When called as pending the status of the
3342 command reply will be checked and if it was erronous the
3343 error will be sent to the original sender of the command.
3344 This way the client always receives the error messages even
3345 though the server was actually the one who received the error
3346 when it resent the command to router, for example. Affected
3347 files silcd/command[_reply].[ch].
3349 * Fixed sending WHOWAS command's error message to client if
3350 the requested client could not be found. It was missing.
3353 * Changed the CMODE and CUMODE commands reply arguments in the
3354 protocol specification. The Channel ID is now sent in both
3355 of the commands to identify the channel. Implemented this
3356 new feature to the client and server. Affected files
3357 lib/silcclient/command_reply.c and silcd/command.c.
3359 * Made better checks for invite and ban lists in the JOIN
3360 command in server. Affected file silcd/command.c.
3362 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3364 * The server now performs the incoming host IP/DNS lookup
3365 using the silc_socket_host_lookup and thus does not block
3366 the server anymore. Affected file silcd/server.c.
3368 * Completed the multi-thread support for SILC Scheduler in
3369 the lib/silcutil/silcschedule.c.
3371 * Fixed the configure.in.pre to detect the pthread correctly
3374 * Fixed a deadlock in silc_task_queue_wakeup in the file
3375 lib/silcutil/silctask.c.
3377 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3379 * Added new function silc_schedule_wakeup that is used in
3380 multi-threaded environment to wakeup the main thread's
3381 schduler. It needs to be used when a thread adds a new task
3382 or removes a task from task queues. After waking up, the
3383 scheduler will detect the task queue changes. If threads
3384 support is not compiled in this function has no effect.
3385 Implemented the wakeup mechanism to both Unix and WIN32
3386 systems. Affected files are lib/silcutil/silcschedule.[ch],
3387 lib/silcutil/unix/silcunixschedule.c and the
3388 lib/silcutil/win32/silcwin32schedule.c.
3390 * Added new function silc_task_queue_wakeup to wakeup the
3391 scheduler by the specified task queue. Affected file
3392 lib/silcutil/silctask.[ch].
3394 * The silc_socket_host_lookup_start now wakes up the scheduler
3395 after adding the timeout task. Affected file is
3396 lib/silcutil/silcsockconn.c.
3398 * The silc_socket_host_lookup is synchronous now if the threads
3399 support is not compiled in. However, the callback is still
3400 called asyncronously through the scheduler, anyway. Affected
3401 file lib/silcutil/silcsockconn.c.
3403 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3405 * Added new function silc_socket_host_lookup to perform
3406 asynchronous IP and FQDN lookups for the socket connection.
3407 Affected files lib/silcutil/silcsockconn.[ch].
3409 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3412 that may or may not compile the mutex support in.
3414 Changed the silc_mutex_alloc interface. It allocates the
3415 mutex now to the sent pointer and returns TRUE or FALSE.
3417 Affected file lib/silcutil/silcmutex.h.
3419 * Wrote the SILC Task Queue interface to support multi-threads.
3420 Affected file lib/silcutil/silctask.[ch].
3422 * Wrote the SILC Scheduler to support multi-threads. Affected
3423 file lib/silcutil/silcschedule.c.
3425 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3428 in lib/silcutil/win32/.
3430 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Defined SILC Mutex API and SILC Thread API and implemented
3433 them for Unix. Affected files are
3434 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3435 lib/silcutil/unix/silcunixmutex.c and
3436 lib/silcutil/unix/silcunixthread.c.
3438 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3440 * Fixed the silc_server_remove_clients_by_server's channel
3441 key re-generation. The hash table handling was incorrect
3442 and would not work with many channels. Affected file is
3445 * Fixed some memory leaks around the server code.
3447 * Rewrote the silc_server_get_users_on_channel to support IPv6
3448 based Client ID's. Affected file silcd/server.c.
3450 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3451 specification. However, a separate document must be written
3452 to define the detailed signing procedure and the payload
3453 associated with the flag. Defined the flag to the
3454 lib/silccore/silcchannel.h as well.
3456 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3458 * Changed the dynamic tables to static size tables in the
3459 lib/silccrypt/silchmac.c.
3461 * Removed GCC dependencies from the code. A patch by cras.
3463 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3465 * Do not show the error "Error receiving packet bla bla"
3466 in server if it really was not an error (-2 means that reading
3467 is pending). Affected file silcd/server.c.
3469 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3471 * Fixed a possible crash in silc_server_remove_clients_by_server
3472 in silcd/server.c. Fixed there also some memory leaks.
3474 * Fixed the silc_idlist_replace_client_id. It could replace
3475 wrong key in the hash table. Affected file silcd/idlist.c.
3477 * Do not check whether there are global users on the channel
3478 if the channel->global_users is FALSE. Affected functions
3479 silc_server_remove_from_one_channel and
3480 silc_server_remove_from_channels in silcd/server.c. Also,
3481 do not check if the removed client is local as we can be
3482 sure that global client was not removed from the channel
3483 and checking for global users is not needed.
3485 * The silc_server_remove_clients_by_server now re-generates
3486 the channel keys correctly for those channels that had
3487 clients removed from them. Affected file silcd/server.c.
3489 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Found the reason of random crashes in the server. We weren't
3492 ignoring the SIGPIPE signal (which can be sent in write())
3493 and it crashed the server. Affected file silcd/silcd.c.
3495 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Assure that sock->user_data is not NULL in the function
3498 silc_server_packet_send in silcd/packet_send.c.
3500 * Disconnect the remote connection if it could not be added
3501 to any ID lists in the server. The affected file is
3504 * Check in silc_server_packet_send[_real/dest] that the
3505 socket is not disconnecting and ignore the data if it is.
3506 Affected file silcd/packet_send.c.
3508 * Define inline to __inline on native WIN32 compilation.
3509 Affected file includes/silcwin32.h.
3511 * Added some explicit type casts for inline code since MSVC
3512 require them. Affected files lib/silcutil/silcbuffer.h,
3513 lib/trq/silcdlist.h and lib/trq/silclist.h.
3515 * Print warning in log files from now on if the packet
3516 decryption fails. Affected file silcd/server.c.
3518 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Changed the `say' client operation's interface to accept
3521 new `type' argument to indicate the type of the message sent
3522 by the library. The application may filter the library's
3523 messages according the type. The affected file is the
3524 lib/silcclient/silcapi.h.
3526 * Added two new functions to lib/silcclient/silcapi.h:
3527 silc_client_del_client and silc_client_del_client_by_id.
3528 Affected file lib/silcclient/idlist.c.
3530 * Moved the clientincludes.h from includes/ to silc/ and
3531 serverincludes.h from includes/ to silcd/.
3533 * The modes for the CMODE and CUMODE are now passed as
3534 uint32 for application with COMMAND_REPLY. The affected
3535 file is lib/silcclient/command_reply.c.
3537 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3539 * /WHOIS without arguments shows client's own information.
3540 Affected file lib/silcclient/command.c.
3542 * Changed PING to not accept any arguments. The specs
3543 says that client can ping only the connected server so
3544 requiring an argument is not needed. Affected file is
3545 lib/silcclient/command.c.
3547 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3549 * Fixed a fatal bug in private message sending and reception
3550 encryption and decryption when using private message keys.
3551 The implementation was incorrect and did not follow the
3552 specification. It causd that some of the message were
3553 lost since it did not use the sending and receiving keys
3554 as the protocol suggests. This has been fixed and will cause
3555 incompatibilities with older clients when sending private
3556 message encrypted with private message keys. Affected files
3557 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3558 and various other in Irssi SILC Client.
3560 Added `responder' boolean argument to the functions
3561 silc_client_add_private_message_key[_ske] to indicate when
3562 the key is added as responder or initiator of the key
3565 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Removed the silc_ske_check_version function and created
3568 a SilcSKECheckVersion callback. Added also a function
3569 silc_ske_set_callbacks that is now used to set all SKE
3570 callbacks. The callback functions are not given to
3571 the SKE functions anymore, but this function is used to
3574 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3576 * Added `silc_version' argument to the silc_client_alloc
3577 to define the version of the application for the library.
3578 The library will use the version string to compare it
3579 against the remote host's (usually a server) version
3580 string. Affected file lib/silcclient/silcapi.h
3582 * Added the KE protocol context to Key Agreement context
3583 in client library so that we can abort the SKE if it
3584 is in process when we get timeout. Affected file is
3585 lib/silcclient/client_keyagr.c.
3587 * Do not resolve the client ID forever if it returns in the
3588 first time that such client does not exist. This was done
3589 for example with private message. Affected file is
3590 lib/silcclient/client_prvmsg.c.
3592 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3594 * Do not add regex.h for WIN32. The affected file
3595 includes/silcincludes.h.
3597 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3598 not work yet 100%. It generates the DLL's automatically
3599 when compiling with --with-win32 under cygwin.
3601 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * lib/contrib/regex.c is not compiled on WIN32.
3605 * Added silc_net_get_socket_opt function to the
3606 lib/silcutil/silcnet.h.
3608 * Added includes/silcwin32.h for WIN32 specific includes
3611 * Do not use ptime structure or any of the posix process
3612 functions on WIN32 in lib/silccrypt/silrng.c.
3614 * Added silc_gettimeofday to provide generic function
3615 for struct timeval on all platforms. Added the function
3616 to lib/silcutil/silcutil.h.
3618 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3620 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3621 library as they clearly belong there. As a plus side we
3622 can make the actual socket connection routines platform
3625 Added also new generic function silc_socket_read and
3626 silc_socket_write (that used to be silc_packet_[read/write].
3627 The implementation of these are platform specific.
3629 * Added WIN32 specific routines of silc_socket_[read/write]
3630 to lib/silcutil/win32/silcwin32sockconn.c.
3632 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3634 * Added preliminary support for native WIN32 compilation under
3635 cygwin (using the -mno-cygwin option for GCC) to the
3636 ./configure.in.pre. The --with-win32 now prepares the
3637 compilation for native WIN32.
3639 * Rewrote the SILC Scheduler interface in the file
3640 lib/silcutil/silcschedule.h. The scheduler is now context
3641 based and does not have anymore any global static scheduler.
3642 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3643 and created lib/silcutil/win32 directory for WIN32 based
3646 * Added Unix specific network routines to the
3647 lib/silcutil/unix/silcunixnet.c and the old
3648 lib/silcutil/silcnet.c includes now only generic routines.
3650 Added WIN32 specific network routines to the
3651 lib/silcutil/win32/silcwin32net.c.
3653 * Added Unix specific utility functions from the
3654 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3656 * Added WIN32 SILC Scheduler to the file
3657 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3660 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Do not handle JOIN notify in the server if the target client
3663 is not registered (idata->registered == FALSE). The affected
3664 file is silcd/packet_receive.c.
3666 * Update the nickrec->founder in event_cumode in the Irssi SILC
3667 client. Affected file irssi/src/silc/core/silc-channels.c.
3669 * Fixed the CUMODE_CHANGE notify handling in the server when
3670 server and router are announcing their clients on channels.
3671 Now the mode changes are saved and notified correctly. The
3672 affected file is /silcd/packet_receive.c.
3674 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3675 They really did not replace the cache entry in the ID Cache.
3676 Now they do that. Affected file silcd/idlist.c.
3678 * Fixed the KICK notify handling in the Irssi SILC client to
3679 update the channel records so that the kicked client does not
3680 appear to be on the channel. The affected file is
3681 irssi/src/silc/core/silc-channels.c.
3683 * Always update the conn->current_channel when executing command
3684 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3686 * Fixed the KILL notify handling in Irssi SILC client to remove
3687 the killed client on all channels.
3689 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Fixed the silc_parse_command_line to remove extra spaces
3692 from the start and end of the arguments. Affected file is
3693 lib/silcutil/silcutil.c.
3695 * Cancel and free any active protocol in the function
3696 silc_server_close_connection. Affected file silcd/server.c.
3698 * Cancel and free any active protocol in the function
3699 silc_client_close_connction. Affected file is
3700 lib/silcclient/client.c.
3702 * Do not execute the KILL command for clients that are in
3703 history (ie. they are not in the network). Affected file is
3706 * Fixed KILL notify handling, client does not crash anymore.
3707 Affected file irssi/src/silc/core/silc-channels.c.
3709 * Reduced the default packet buffer size from 2048 to 1024 in
3710 lib/silccore/silcpacket.c.
3712 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3713 counter to the SKE context that is incresed when the SKE library
3714 performs async operation outside the library. If the outside
3715 process frees the SKE context and FREED status will be set
3716 and the library will detect after the sync operation that the
3717 libary is freed. The affected files are
3718 lib/silcske/silcske[_status].[ch].
3720 * Resolve the client entry information in the function
3721 silc_client_channel_message to assure that NULL pointer is not
3722 passed as client entry to the application. */
3724 * Fixed the task timeout calculation to assure that there is
3725 never negative timeouts. The affected file is
3726 lib/silcutil/silcschedule.c.
3728 * Fixed the channel user mode notification sending in server.
3729 It was sent point-to-point to the router (or to server by router)
3730 but it needs to be destined to a channel. The routines now
3731 supports sending the channel user mode notifys to the channels
3732 when announcing clients and channels. Affected files are
3733 silcd/server.c and silcd/packet_receive.c.
3735 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3736 It did not actually replace the old channel entry in the cache.
3737 Affected file lib/silcclient/client_notify.c.
3739 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Fixed a possible crash in silc_packet_send_prepare. It now
3742 assures always that there is enough space in the buffer and
3743 at the tail area of the buffer (for MAC).
3745 Fixed the inbound buffer reallocation in silc_packet_read.
3746 It was old code and did not handle the reallocation correctly.
3749 The affected file is lib/silccore/silcpacket.c.
3751 * Fixed buffer overflow in silc_parse_nickname in the file
3752 lib/silcutil/silcutil.c.
3754 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * make install generates new server keys only if there is not
3759 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3762 Added check that if the NOREPLY is set then we will not send
3763 the away message. This avoids infinite loop of away messages
3764 if both clients are away. The affected file is
3765 lib/silcclient/client_prvmsg.c.
3767 * Fixed client crash if /NICK was given without arguments.
3768 Affected file lib/silcclient/command.c.
3770 * Server does not send the invite list in INVITE command back
3771 to the client if the list was not altered. Added this notion
3772 to the protocol spec as well. Affected file silcd/command.c.
3774 Fixed possible crash in INVITE command by checking the
3775 value of silc_server_get_client_route command.
3777 * Fixed the INVITE notify type handling. The arguments are now
3778 taken in correct order and client does not crash. The affected
3779 file is irssi/src/silc/core/silc-channels.c.
3781 Removed the "Inviting xxx to channel" message from the
3782 client library away and let the application handle it.
3783 Affected file lib/silcclient/command.c. Added that message
3784 to Irssi SILC client's message formats.
3786 * Fixed CMODE command crash in client. It now checks the
3787 amount of arguments correctly and does not crash. The affected
3788 file is lib/silcclient/command.c.
3790 * Do not create new channel automatically in silc_channels_join
3791 but check whether the channel by that name already exists.
3792 Affected file irssi/silc/core/silc-channels.c.
3794 * Do not send the SERVER_SIGNOFF to router if the disconnected
3795 entity was the router. Affected file silcd/server.c.
3797 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3798 SILC client as it was missing from there.
3800 Added the handling of the KICK notify to the Irssi SILC client
3801 as it was missing. Added "you have been kicked" message to
3802 Irssi SILC client's message modules formats.
3804 Added the handing of the KILL notify to the Irssi SILC client
3805 as it was missing. Added the kill message module formats
3808 The affected file is irssi/src/silc/core/silc-channels.c.
3810 * The router did not save the channel mode the server announced.
3811 Affected file silcd/packet_receive.c.
3813 * Fixed a possible crash in INFO command in server. If the
3814 server did not provide the server info it crashed. Affected
3815 file silcd/command.c.
3817 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Fixed the GETKEY command in the server to check also the
3820 global list. Otherwise the GETKEY would not work correctly
3821 in normal SILC server. Affected file silcd/command.c.
3823 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Fixed GETKEY crash, it crashed if the command did not succseed.
3827 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3830 is now real and not just an macro interface to GMP.
3832 Removed the entire GMP from the source tree and imported new
3833 NSS MPI library instead. Reason for removing GMP is that it is
3834 extremely large and compiles extremely slow. The NSS MPI
3835 is only a few files and compiles in less than 10 seconds.
3836 The speed is also about the same as GMP. The MPI is imported
3837 to lib/silcmath/mpi.
3839 If the system has GMP installed we will still use the GMP.
3840 If it is not then the NSS MPI will be compiled.
3842 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Merged a long nickname (127 characters long) crash bugfix from
3845 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3847 * Merged a freed memory reference bugfix from Irssi CVS tree.
3848 Affected file irssi/src/core/commands.c.
3850 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Added the server's public key sving and verification to the
3853 server when performing the SKE. This was missing and the
3854 remote server's (or router's) public key was accepted without
3855 checking whether we have it previously or trust it at all.
3856 Affected file silcd/protocol.c.
3858 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Check in the silc_server_timeout_remote if protocol is active
3861 and make sure that the protocol's final callback is called so
3862 that all memory if freed. Affected file silcd/server.c.
3864 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * silc_server_whois_send_reply crashed the server if the nickname
3867 was 127 characters long. Affected file silcd/command.c.
3869 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Added sanity check to the silc_server_new_client. If the hostname
3872 is provided inside username then check that the provided hostname
3873 really is the same as the resolved one. If the hostname was not
3874 resolved then check it from the public key. Affected file is
3875 silcd/packet_receive.c.
3877 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3878 if the server disconnected us and the connection is not valid
3879 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3881 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3882 the library to the lib/silcutil/silcutil.[ch].
3884 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Close log file after open. Affected file
3887 lib/silcutil/silclog.c.
3889 * Check whether sock == NULL in silc_client_send_packet and return
3890 if it is. Affected file lib/silcclient/silcclient.c.
3892 * Check rec->entry == NULL in the Irssi SILC Client before
3893 sending the channel message. Affecte file is
3894 irssi/src/silc/core/silc-servers.c.
3896 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Merged a splitted window bugfix from Irssi CVS tree. The
3899 affected file is irssi/src/fe-text/textbuffer-view.c.
3901 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3902 It did not print nickname.
3904 * Improved the distributions system a bit.
3906 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3909 irssi/src/fe-text/gui-window.c.
3911 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3912 to in-active server. The affected file is
3913 irssi/src/silc/core/client_ops.c.
3915 * Resolve the client in USERS command reply if the entry does
3916 not have username resolved. The affected file is
3917 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3918 command to WHOIS command to really resolve stuff. The USERS
3919 is not used any more in any critical section so WHOIS can
3920 be used even though it might be slower than IDENTIFY.
3922 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3925 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Changed the protocol API a bit more consistent in the
3928 lib/silccore/silcprotocol.[ch].
3930 * Changed the following headers to ROBODoc format:
3932 lib/silccore/silcpayload.h
3933 lib/silccore/silcprotocol.h
3934 lib/silccore/silcsockconn.h
3936 All core library headers are now formatted.
3938 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Fixed a bug in Irssi SILC client; do not show that you are
3941 server/router operator if you really are not. Affected file is
3942 irssi/src/silc/core/client_ops.c.
3944 * Renamed silc_command_free_payload to silc_command_payload_free.
3945 Affected file lib/silccore/silccommand.h
3947 * Added silcmath.h to include the prototoypes of various routines
3948 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3951 * Changed the following headers to ROBODoc format:
3953 lib/silccore/silcchannel.h
3954 lib/silccore/silccommand.h
3955 lib/silccore/silcid.h
3956 lib/silccore/silcidcache.h
3957 lib/silccore/silcmode.h
3958 lib/silccore/silcnotify.h
3959 lib/silccore/silcpacket.h
3960 lib/silcmath/silcmath.h
3962 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Added checking to the server code not to start the server if
3965 ciphers and stuff are not configured properly. Affected files
3966 silcd/serverconfig.[h] and silcd/server.c.
3968 * Changed the layout of the header files of the public interfaces
3969 in the SILC libraries. The new layout supports ROBODoc
3970 documentation tool (and some others) so that it is easy to create
3971 a library reference manual. All the other headers and source
3972 code must still follow the CodingStyle document. Also source
3973 code must not include these ROBODoc stuffs, only the headers.
3974 Furthermore, all public interface headers must now be named
3975 by using `silc' prefix, example: silcapi.h, silccipher.h.
3976 Some files were renamed due to this. All the other headers
3977 must not be used as public interfaces. I will update the
3978 CodingStyle document later. Changed following headers, so far:
3980 lib/silcclient/silcapi.h
3981 lib/silccore/silcauth.h
3982 lib/silccore/silcprivate.h
3983 lib/silccrypt/silcdh.h
3985 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3989 * Removed silc_client_packet_send_flush from the client library
3990 as it is not needed. Affected file lib/silcclient/client.[ch].
3992 * Added printing of message of unresolved authentication method
3993 to the Irssi SILC client. Added it to the module formats.
3994 Removed the same message from the client library.
3996 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Added new distribution feature, DISTLABEL. Every distribution
3999 can define own preprocessor label that can be used in the
4000 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4001 file distributions, acconfig.h.pre and prepare.
4003 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added Makefile.defines_int to include the actual definitions
4006 for Makefile.defines.in. Tested the new distribution system,
4007 created distributions and tested installation.
4009 * Added AWAY message printing to the Irssi SILC client. Added
4010 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4012 * Added SCONNECT command to call the SILC's CONNECT command.
4013 Cannot use CONNECT directly since Irssi uses that internally.
4014 Affected file irssi/src/silc/core/silc-servers.c.
4016 Added ACTION local command. It is same as ME command but takes
4017 the channel as mandatory argument.
4019 Rewrote some of the Irssi's help files to suite for SILC
4022 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Added Makefile.defines[.in] that should for now on be included
4025 in all Makefile.am file in the source tree. That file includes
4026 all common compilation definitions for SILC source tree.
4028 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Minor changes to the ./prepare script to change the package
4031 name according the distribution name to the configure.in.
4033 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Created new distribution system. Added file `distributions'
4036 that defines all the distributions that can be created out of
4037 the SILC source tree. The ./prepare script now reads that
4038 file to determine how to prepare the distributions. The
4039 first argument to the ./prepare is the name of the distribution
4040 and second is the version of the distribution. If given
4041 without arguments it creates the default (toolkit) distribution
4042 with the default version (defined in ./prepare).
4044 All Makefile.am files that are subject to the distributions
4045 are now named as Makefile.am.pre. These are ./Makefile.am
4046 and lib/Makefile.am. Others may be changed later.
4048 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Added invite list, ban list, some key management and connection
4051 error message printing to module formats in the Irssi SILC client.
4053 * Added new silc_client_set_away_message to set the away message
4054 that is back to the person who sent private message. The
4055 affected file lib/silcclient/silcapi.h and the
4056 lib/silcclient/client_prvmsg.c.
4058 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Fixed the private message sending in the Irssi SILC client,
4061 added local command KEY to the Irssi SILC client.
4063 Added key management and key agreement message formats to the
4064 irssi/src/fe-common/silc/module-formats.[ch].
4066 Added USERS (alias WHO) printing, server/router operator
4067 indication and LIST command printing to the module formats.
4069 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Fixed channel joining notify handling, cumode notify handling
4072 from Irssi SILC client.
4074 * Added SILC specific module-formats to the Irssi SILC client so
4075 that SILC specific message hilighting, colors etc is possible.
4076 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4078 Added channel mode, channel user mode, actions, notices,
4079 whois and whowas printing to the the module-formats.c.
4081 * Fixed a bug in channel deletion in the server. The channel
4082 is not left to the cache even if the channel founder auth mode
4083 is set when there are no users anymore on the channel. Affected
4084 file silcd/server.c.
4086 * The silc_net_localhost now resolves the entire hostname including
4087 the domain name. Affected file lib/silcutil/silcnet.c.
4089 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Changed the ask_passphrase client operation to be ascynchronous.
4092 It has now a completion callback and a context that the
4093 application must call after it has got the passphrase from
4094 the user. Affected files lib/silcclient/silcapi.h,
4095 lib/silcclient/protocol.c, lib/silcclient/command.c and
4098 Added SilcAskPassphrase callback that the application calls
4099 to deliver the passphrase to the library.
4101 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4102 The public key verification and especially a certificate
4103 verification is asynchronous procedure.
4105 Added new SILC_SKE_STATUS_PENDING status to indicate the
4106 request is pending and a callback will be called to finalize
4109 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4110 indicate that remote end did not send its public key (or
4111 certificate), even though we require it. Added check for this
4112 condition in the SKE. This was a security bug, now fixed.
4114 Defined new SilcSKEVerifyCbCompletion callback that is called
4115 when the verification process is completed.
4117 The affected files lib/silcske/silcske_status.h and
4118 lib/silcske/silcske.[ch].
4120 * Changed the verify_public_key client operation to be async
4121 as well. Defined SilcVerifyPublicKey callback that is used to
4122 indicate the success of the public key verification process.
4124 Changed the server and client to use the new async client
4127 * Changed the Irssi SILC client's internal scheduler to be called
4128 twice as many times as it used to be. As a result the client
4129 should be a bit faster now. Affected file is
4130 irssi/src/silc/core/silc-core.c.
4132 * Added support to Irssi SILC client of asynchronous public key
4133 verification and passphrase inquiry. Affected file is
4134 irssi/src/silc/core/silc-core.c.
4136 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Do not say "You have left channel %s" in client library.
4139 Moved it to the application. Affected files are
4140 lib/silcclient/command.c and silc/client_ops.c.
4142 * Fixed silc_client_get_clients. Command context was not
4143 duplicated and was freed memory in the callback. Affected
4144 file lib/silcclient/idlist.c.
4146 * Do not say "you are now talking..." on JOIN command in the
4147 client library. The appliation must handle it.
4149 * Do not say ".. changed topic to" in command reply in the
4150 client libary. The application must handle it.
4152 * Fixed TOPIC command sending in the client library.
4154 * Fixed a memory leak in silc_client_command_free in the file
4155 lib/silcclient/command.c.
4157 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Imported a modified version of Irssi client to the source tree.
4160 The Irssi will be used to create a new client called
4161 Irssi SILC. Imported to irssi/.
4163 Added silc_core_init_finish function to the Irssi. Affected
4164 file irssi/configure.in.
4166 A lot changes in the Makefile.ams around the irssi tree.
4168 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Do not rehash if the new size is same as the old size of the
4171 hash table, in the silc_hash_table_rehash*. The affected file
4172 lib/silcutil/silchashtable.c.
4174 * Replaced hash_table_del_by_context calls from the server
4175 (when channel->user_list and client->channels) to the
4176 hash_table_del as it is sufficient and faster.
4178 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added silc_hash_table_list, silc_hash_table_get and the
4181 SilcHashTableList structure to provide an alternative way to
4182 traverse the hash table. The affected files are
4183 lib/silcutil/silchashtable.[ch].
4185 * Changed the server's idlist routines to use the hash table
4186 routines to optimize the code.
4188 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Replaced the client entry's `channel' list and channel entry's
4191 `user_list' list to hash tables for optimized lookup. Changed
4192 the code to use the hash table interface around the code.
4193 Affected file lib/silcd/idlist.[ch].
4195 * Added `auto_rehash' boolean argument to the function
4196 silc_hash_table_alloc to indicate whether the hash table should
4197 auto-rehash when it thinks is appropriate time. It will
4198 increase the hash table size if the there is twice as much
4199 entries in the table than the size of the table, and will
4200 decrease the size if there are twice as less entries than
4201 the size of the table.
4203 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4207 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * silc_idcache_purge_by_context deletes the entry now by context
4210 as it is supposed to do. Affected file lib/silccore/idcache.c.
4212 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4213 client is not anymore valid (WHOWAS givens the info) and not
4214 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4216 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Removed the `data' and `data_len' arguments from the ID Cache
4219 interfaces and added `name' argument. ID Cache does not handle
4220 anymore the binary data only a names associated with given ID.
4222 * When hashing a Client ID with silc_hash_id the entire ID is
4223 not hashed anymore, instead only the hash of the Client ID is
4224 hashed. This way we can access the Client ID from the cache
4225 with Client ID but with the hash of the ID (which is a hash of
4226 the nickname) as well without any difference in performance.
4228 Added also silc_idcache_find_by_id_one_ext to do one on one
4229 searching when we have the actual ID. Added also function
4230 silc_hash_client_id_compare. The affected files are
4231 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4233 * When hashing the name associated with a ID it is always done
4234 in lowercase. This way we can access the cache without worrying
4235 about case-sensitivity, even though, for example nicknames are
4238 * Fixed a bug in server with channel message sending. It put
4239 wrong ID type as destination ID. The affected file
4240 silcd/packet_send.c.
4242 * silc_idcache_del_by_context now deletes from all hash tables
4243 by context. Affected file lib/silccore/idcache.c.
4245 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Changed the client library to use the new ID Cache interface.
4248 Changes around the source tree.
4250 * Added silc_hash_table_rehash_ext to rehash with specific
4251 hash function. Affected file lib/silcutil/silchashtable.[ch].
4253 * Added silc_hash_string_compare to compare two strings in the
4254 hash table. Affected file lib/silcutil/silcutil.[ch].
4256 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Added new function silc_idcache_del_by_context into the
4259 lib/silccore/idcache.[ch].
4261 * Changed the server's ID list routines to use the new ID Cache
4262 interface. Changes around the source tree.
4264 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Added silc_hash_table_del[_by_context]_ext functions in to the
4267 lib/silcutil/silchashtable.[ch].
4269 Removed silc_hash_table_find_all* routines and added new
4270 silc_hash_table_find_foreach to replace them.
4272 Added silc_hash_table_replace_ext function as extended
4273 replacing function. Separated the simple hash table interface
4274 from the extended hash table interface in the file
4275 lib/silcutil/silchashtable.h.
4277 * Fixed minor bugs and changed it to use some of the new
4278 hash table functions in lib/silccore/idcache.c
4280 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Added new function silc_hash_table_find_all to return all keys
4283 in the hash table by the specified key. As the hash table is
4284 collision resistant it also makes it possible to have several
4285 duplicate keys in the hash table. This function may be used to
4286 find all of the keys from the hash.
4288 Added user_context arguments to the SilcHashFunction,
4289 SilcHashCompare and SilcHashDestructor to deliver user specified
4292 Added new fuctions silc_hash_table_find[_all]_ext to do
4293 extended lookup with specified hash and compare functions and
4294 specified user contexts.
4296 Added new function silc_hash_table_add_ext to add the key
4297 with specified hash function and user context.
4299 Added new function silc_hash_table_foreach to traverse all
4300 entrys in the hash table. Added SilcHashForeach callback
4303 Added new function silc_hash_table_del_by_context to delete
4304 the entry only if the context associated with the key matches.
4306 Affected files are lib/silcutil/silchashtable.[ch].
4308 * Removed silc_hash_[server/client/channel]_id and added just
4309 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4310 silc_hash_id_compare to compare two ID's using as the hash table
4311 comparison function. Added also silc_hash_data to hash
4312 binary data and silc_hash_data_compare to compare it.
4314 * Removed silc_idlist_find_client_by_hash as it is not needed
4315 anymore. Affected file silcd/idlist.[ch].
4317 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4318 to use internally the SilcHashTable. The new ID Cache is a lot
4319 faster than the old one. Some of the ID Cache interface was also
4320 rewritten and obsolete and stupid functions were removed.
4322 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Added entry_count field to the SilcHashTable to keep the number
4325 of the entries in the table. Implemented the function
4326 silc_hash_table_rehash. Added new function
4327 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4329 Fixed a minor bug in silc_hash_table_free.
4331 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4332 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4333 into the lib/silcutil/silcutil.[ch].
4335 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Implemented a collision resistant hash table into the
4338 lib/silcutil/silchashtable[ch]. See the header and the source
4339 for the SilcHashTable API.
4341 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Merged dotconf version 1.0.2 into lib/dotconf.
4345 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Do not compile anything in lib/silcsim/* if the SIM support
4348 is not enabled. The tree should now compile without problems
4351 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Compiled the SILC under cygwin. Compiled and tested briefly
4354 without problems. More tests needed. The SIMs didn't compile
4357 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4359 * Fixed possible crash in silc_get_username in the
4360 lib/silcutil/silcutil.c.
4362 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Fixed a va_arg in silc/client_ops.c.
4366 * Oops, RC5 routines were named AES and caused some problems
4367 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4369 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Added new SilcIDIP structure into the lib/silccore/id.h and
4372 replaced the old `ip' fields from all SILC ID's to that type.
4373 This is a step towards IPv6 support.
4375 The silc_id_get_len takes now the ID as an extra argument.
4376 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4377 both IPv4 and IPv6 based ID's.
4379 The affected files are lib/silccore/id.[ch] and other files
4380 around the tree using these routines.
4382 * Removed the ID length arguments in server from various
4383 silc_server_send_notify_* routines -> they are not needed
4386 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Fixed memory leak in silc_encode_pem_file in the file
4389 lib/silcutil/silcutil.c.
4391 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Check minor version as well in the SKE. Affected files are
4394 silcd/protocol.c and lib/silcclient/protocol.c.
4396 * Added --identifier option to the server so that an identifier
4397 can be when creating the public key for the server. Affected
4398 file is silcd/silcd.c.
4400 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4401 lib/silccrypt/silcpkcs.c.
4403 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Register default ciphers and stuff when using -C option with
4406 the server. Affected file sildc/silcd.c.
4408 * Put back the servers public key filename format, it is better
4409 than the new one. For now, the client keys are saved with the
4410 new filename format. The affected file silc/client_ops.c.
4412 * Implemented the Cipher API for the rest of the ciphers that
4413 did not implement it or implemented it the wrong way.
4415 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Register default ciphers and stuff when using the -S option
4418 in the client. Affected file silc/silc.c. Same also when
4419 creating new key pair with -C option.
4421 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Fixed the silc_verify_public_key client operation function to
4424 save the public keys differently. The fingerprint is now
4425 used as filename and not the hostname. This way also the
4426 client keys are saved uniquely and not with hostnames. The
4427 affected file is silc/client_ops.c.
4429 * Trimmed the silc_hash_fingerprint function to remove extra
4430 whitespaces from the end of the fingerprint. The affected
4431 file is lib/silccrypt/silchash.c.
4435 * Added silc_cipher_register_default function to register all
4436 default ciphers. It can be used when configuration files
4437 does not exist and the application does not want any specific
4438 ciphers in any specific order.
4440 The SilcDList is now used as silc_cipher_list dynamically
4441 allocated cipher list. Removed the static list all together
4442 and now all ciphers must be allocated to the dynamic list.
4443 The silc_cipher_alloc routine was changed to check only the
4446 All silc_cipher_* routines that used to return int returns
4449 The affected files lib/silccrypt/silccrypt.[ch].
4451 * The same thing was done to silc_hash_* as for silc_cipher_*
4452 routines. Affected files lib/silccrypt/silchash.[ch].
4454 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4455 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4456 Added also silc_pkcs_[un]register[_default] functions.
4457 Removed the data_context from the PKCS API.
4459 * Added silc_hmac_register_default function to register default
4460 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4461 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4462 to unregister all hmacs at once.
4464 * Register the default ciphers, hash functions, PKCSs and HMACs
4465 if client's configuration file does not exist. The affected
4468 * The client did not load the hash functions from the SIM
4469 modules at all. Added support for this. Affected file is
4470 silc/clientconfig.c.
4472 * When decoding public key with silc_pkcs_public_key_decode, check
4473 the supported algorithm only if PKCS are registered. Affected
4474 file lib/silccrypt/silcpkcs.c. The same was done with the
4475 silc_pkcs_private_key_decode.
4477 * Fixed the SILC List routines to keep the list always in order.
4478 It used to change the list's order when traversing the list but
4479 not it preserves the order. Affected file lib/trq/silclist.h.
4481 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Added the client library to use the SilcSocketConnection's
4484 reference counter (by silc_socket_dup) to prevent the bug that
4485 the socket object may be freed underneath async operation.
4487 * The name resolv library checking fixes in the configure.in.pre.
4490 * Created new version of the protocol drafts for future
4491 development. The -03 drafts are the ones that will be changed
4492 in the trunk now and the -02 will remain as they are.
4494 * Send list of CUMODE notifys to the router when announcing
4495 the channel users to the router. Affected file silcd/server.c.
4496 If the router receiving channel founder CUMODE for a channel
4497 that already has channel founder it will send CUMODE notify
4498 to the sender to remove the channel founder rights from the
4499 announced client. Affected file silcd/packet_receive.c.
4501 * The CUMODE notify may now use Server ID as well as the entity
4502 who changes the mode. Updated protocool specs.
4504 * Updated INSTALL and README files.
4506 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * New web pages in the http://silc.pspt.fi. The pages was
4513 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Implemented the [DenyConnectin] config section in the server.
4516 Added silc_server_config_denied_conn to check whether incoming
4517 connection is denied. Affected file silcd/serverconfig.[ch].
4519 * Do not check the ports when checking the incoming configuration
4520 data if the port is 0, meaning any. Affected file is
4521 silcd/serverconfig.c.
4523 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Fixed buffer overflow in silc_string_compare in the file
4526 lib/silcutil/silcutil.c.
4528 * Fixed double free in silc_server_command_leave in the file
4531 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Fixed the version checking in the server. Affected file is
4536 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Fixed the configuration data fetching when accepting new
4539 connections in the server. Affected file silcd/server.c.
4541 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Added `sender_entry' argument to the function
4544 silc_server_packet_relay_to_channel so that we can check
4545 whether some destination actually belongs to the same route
4546 the sender belongs (ie, we must not resend the packet to the
4547 sender). Affected file silcd/packet_send.[ch].
4549 * Added `servername' field to the SilcClientEntry in the server
4550 to hold the name of the server where client is from. Affected
4551 file is silcd/idlist.h.
4553 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Moved the channel message encrypting in the router betwen
4556 router connections from silc_server_channel_message to the
4557 silc_server_packet_relay_to_channel since we want to check
4558 whether we have anybody channel before encrypting anything.
4559 Affected files silcd/packet_[receive/send].c.
4561 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Fixed the [AdminConnection] server config section to support
4564 multiple entries. Affected file silcd/serverconfig.c.
4566 * Added support into the server to check the validity of the
4567 incoming connection before executing any KE or authentication
4570 * The connection configuration is now saved to the KE and
4571 connection auth protocol contexts and not fetched anymore in
4572 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4574 * The local hosts listenning address and port is also resolved
4575 now when starting the server. We want to have the socket object
4576 to include the real address and port for the listener. Added
4577 new function silc_net_check_local_by_sock into the files
4578 lib/silcutil/silcnet.[ch].
4580 * Fixed a broadcast bug in server -> do not broadcast if we
4583 * Fixed a routing bug. Do not route broadcast packets ever.
4584 Broadcast packets must be processed always and not routed since
4585 they may be destined to some other host than yourself and thus
4586 would get routed without no good reason. Affected file is
4589 * Added function silc_server_config_is_primary_route to check
4590 whether primary router connection has been configured (a router
4591 configuration that we are initiating). If there is not, we
4592 will assume that there is only two routers in the SILC network
4593 and we will use the incoming router connection as our primary
4594 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4596 * Changed the order of the broadcasting. Broadcast _after_ the
4597 packet has been processed not before. Affected file is
4600 * Fixed a [ClientConnection] parsing bug. The port was never
4601 parsed correctly thus resulting to port 0. Affected file
4602 silcd/serverconfig.c.
4604 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4605 argument and did not set the broadcast packet flag. Affected
4606 file silcd/packet_send.c. Fixed same bug in the function
4607 silc_server_send_notify as well.
4609 * If we receive NEW_ID packet for our own ID in the server, ignore
4612 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Removed the nickname from the Private Message Payload.
4617 Updated the code and the protocol specs.
4619 * Updated protocol specs for submitting to the IETF.
4621 * Tweaked the Random Number Generator a bit. Affected file
4622 lib/silccrypt/silcrng.c. Exported a new function
4623 silc_rng_[global]_add_noise which can be used to add more
4626 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Do not parse packets with different timeout when protocol
4629 is active -> may cause problem with rekey. Affected file
4632 * When server receives signoff notify it must not create
4633 new channel key if the client is on any channels since the
4634 sender of the signoff notify will create it.
4636 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added printing of error messages during SKE protocol from the
4639 failure packet sent by server during SKE. Affected file
4642 * Removed the client's failure_callback handling with timeout
4643 and handle it immediately when received.
4645 * The SKE library returned wrong type in SUCCESS and FAILURE
4646 packets. They must be 32 bit MSB not 16 bit MSB.
4648 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Ok, rewrote the logic of the re-key and now it seems to work.
4651 I tested it on high traffic with frequent re-keys without
4652 problems. Added hmac_receive (and renamed hmac to hmac_send)
4653 in SilcClientConnection in lib/silcclient/client.h and
4654 in SilcIDListData in silcd/idlist.h. Also, removed the
4655 SilcPacketParserContext's cipher and hmac fields as they are
4656 not needed anymore and actually caused some problems when
4657 the ciphers and hmac's changed underneath the packet parser.
4659 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * If re-key protocol is active then process the incoming packets
4662 synchronously since we must assure that icoming packets encrypted
4663 with the old key is processed before the new keys is set to
4664 use. This is true other packets than for REKEY packets.
4665 Affected file silcd/server.c. The same was done to client library
4666 as well, affected file lib/silcclient/client.c.
4668 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Fixed bug in client and server to accept the force send if
4671 the packet is send from silc_[server/client]_packet_process
4672 function. Otherwise the packets are never delivered, oops.
4674 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Disable force sending of packets when REKEY protocol is active.
4677 We must assure that no packet is sent directly when rekey is
4678 performed. All packets must be sent through packet queue.
4679 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4680 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4681 function is silc_[server/client]_packet_send_real to check
4684 * Replaced the SIM paths from example config files to
4685 /usr/local/modules. Also, make install creates now
4686 /usr/local/silc/logs directory to hold all the SILC server
4689 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Made the configure.in.pre work on Solaris. Patch by salo.
4693 * Made all ciphers compatible with non-x86 machines. Defined
4694 CBC mode macros into lib/silccrypt/ciphers_def.h.
4696 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Fixed the make install.
4700 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * When MAC computation fails the silc_packet_decrypt returned 0
4703 even though it was supposed to return -1. Fixed this. The
4704 affected file is lib/silccore/silcpacket.c.
4706 * Do not replace the config files in /etc/silc (in make install)
4707 if they already exist. Affected file ./Makefile.am.
4709 * Do not send re-key packets immediately but through packet queue.
4710 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4712 * Changed silc_net_check_host_by_sock to return FALSE if the
4713 IP/DNS could not be resolved. Though, it returns the IP address
4714 now even if it could not resolve it (but returns also FALSE).
4715 Affected file lib/silcutil/silcnet.[ch].
4717 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Added silc_pkcs_decode_identifier to decode the public key's
4720 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4721 Added also silc_pkcs_free_identifier. Added also new context
4722 SilcPublicKeyIdentifier.
4724 * Added -S option to the silc client. It is used to dump the
4725 contents of the specified public key file.
4727 * Changed the PKCS api to return the public key length when
4728 setting the public key.
4730 * Fixed a fatal bug in the public and private key file loading.
4731 Affected file lib/silccrypt/silcpkcs.c.
4733 * Execute the packet parsing for client with zero (0) timeout
4734 if the protocol is active. Affected file silcd/server.c.
4736 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Made the key generation options to the silcd program. Added
4739 -C option, equivalent to client's option.
4741 * Added new [ServerKeys] config section to the server. It
4742 configures the server's public and private key.
4744 * Defined generic Public Key Payload into the protocol
4745 specification to send specific type of public keys and
4748 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4749 public key or certificate.
4751 * Implemented the GETKEY command to the server and to the
4752 client library and on user interface.

4760 * Added SilcServerRekey context into silcd/idlist.h.
4762 * Added the PFS support as defined in the specification to the
4763 SKE protocol. Affected files lib/silcske/*.c.
4765 * Added `ske_group' field to the SilcServerRekey context to hold
4766 the number of the SKE group that is used with PFS in re-key.
4767 Affected file silcd/idlist.h.
4769 * Added PFS re-key support to the server. Affected file is
4772 * Added silc_protocol_cancel to cancel execution of the next
4773 state of the protocol. Affected file is
4774 lib/silccore/silcprotocol.[ch].
4776 * Added the re-key support with and without PFS to the client
4777 library. Re-key is performed once in an hour, by default.
4779 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4780 Added silc_client_rekey_callback and silc_client_rekey_final.
4781 Affected files are lib/silcclient/protocol.[ch] and
4782 lib/silcclient/client.[ch].
4784 * Removed the `hmac_key' and `hmac_key_len' fields from the
4785 SilcClientConnection structure; not needed. Affected file is
4786 lib/silcclient/client.h.
4790 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Do not ask whether user wants to use the negotiated private key
4793 for private messages, just use it. Affected file is
4794 silc/local_command.c.
4796 * Added `send_enc_key' and `enc_key_len' fields to the
4797 SilcIDListData structure since they are needed in the re-key
4798 phase. Affected file is silcd/idlist.[ch].
4800 * Implemented the simple re-key protocol into the server.
4801 Affected files silcd/server.c and silcd/protocol.[ch]. The
4802 re-key will be performed once in an hour, by default.
4804 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4805 Added silc_server_rekey, silc_server_rekey_callback and
4806 silc_server_rekey_final.
4808 * Removed Tunneled flag from the protocol. Updated the code
4809 and the specifications.
4811 * Adde `pfs' field to the SilcIDListData to indicate whether
4812 the PFS is to be performed in the re-key. Affected file is
4815 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4818 int64 of at least the xintXX size. If void * is less that 4
4819 bytes uint32 * will be used. Defined bool as boolean.
4821 * Changed _ALL_ unsigned long and unsigned int to uint32,
4822 unsgined short to uint16 in the source tree.
4824 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4825 not handle clients that has entry->data.registered == FALSE.
4826 They are not in the network anymore. Affected file is
4829 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Implemented the sending of the SERVER_SIGNOFF notify in the
4832 server. Affected file is silcd/server.c.
4834 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4835 Added also silc_notify_payload_encode_args into the
4836 lib/silccore/silcnotify.[ch].
4838 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4839 Affected file silcd/packet_receive.c.
4841 * Implemented the SERVER_SIGNOFF notify handling in the client
4842 library. Affected file lib/silcclient/client_notify.c. Also,
4843 implemnted the printing of the SERVER_SIGNOFF info to the
4844 application. Affected file silc/client_ops.c.
4846 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4847 if the deleting was successful. Affected file silcd/idlist.[ch].
4849 * Added support for public key authentication in the connection
4850 authentication protocol in the client library. Affected file
4851 lib/silcclient/protocol.c.
4853 * Changed the server's silc_idlist_get_clients_by_* interface
4854 to support already allocated array so that new entries may be
4855 added to pre-allocated array. Affected file silcd/idlist.[ch].
4856 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4857 and command replies.
4859 * All command reply functions in the server now calls the
4860 pending command callback even if error occured. This way the
4861 error will be delivered to the client as well. Affected files
4862 silcd/command.c and silcd/command_reply.c.
4864 * Fixed INFO command to return local server's info if no server
4865 was provided. Affected file lib/silcclient/command.c.
4867 * Removed RESTART command for good. Updated the code and the
4870 * Rewrote parts of the task system. It is a bit simpler now.
4871 Removed unsued task priorities. The affected files are
4872 lib/silcutil/silctask.[ch].
4874 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Moved the USERS printing from the library to the application.
4877 Affected files lib/silcclient/command.c and silc/client_ops.c.
4879 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Added channel key re-key support. The re-key is perfomed
4884 only by the router and is done once in an hour. Added `rekey'
4885 field to the SilcChannelEntry in the server. Affected files
4886 silcd/server.c and silcd/idlist.h.
4888 * Added silc_task_unregister_by_context into the file
4889 lib/silcutil/silctask.[ch].
4891 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Added SILC_UMODE_GONE mode to indicate when the client is not
4894 present in the SILC network. Added also support to the local
4895 command AWAY that will set this mode. Added support of showing
4896 "xxx is gone" in WHOIS command. The USERS command shows the
4897 gone status as well.
4899 * Fixed setting server and router operator privileges in the
4900 server's UMODE command. Affected file silcd/command.c.
4902 * Merged the SKE KE1 and KE2 payloads into one payload. The
4903 new KE payload is equivalent to the old KE2 payload.
4905 Cleaned up the SKE Start Payload parsing. It now uses the
4906 simple buffer unformatting to do the parsing. A lot faster
4909 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4910 to the SKE that is used to indicate whether both of the SKE
4911 parties should perform authentication. By default only the
4912 responder performs authentication. By setting this flag also
4913 the initiator must do authentication. By default it is unset
4914 since in normal SKE case, client to server connection, only
4915 the responder should do authentication. When doing SKE between
4916 two clients both should perform authentication. Updated the
4917 code and the protocol specs.
4919 * A little fix to IDENTIFY command in the server. Search the
4920 client first by hash not nickname. Affected file is
4923 * Fixed the silc_client_close_connection to support closing
4924 the client to client connections wihtout deleting too much
4925 data. Affected file lib/silcclient/client.c.
4927 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4928 are received if protocol used to be active but is not anymore
4929 the application would crash due to NULL pointer dereference.
4930 Affected files silcd/server.c and lib/silcclient/client.c.
4932 * Added `hash' field to the SilcClientConnection to include
4933 the hash function negotiated in the SKE protocol.
4935 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4936 to set the channel founder authentication data. A client can
4937 claim the founder rights later by providing the authentication
4938 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4939 This way the channel founder can regain the channel founder
4940 privileges even it is left the channel. This works only on
4941 local server and the client must be connected to the same
4942 server to be able to regain the founder rights. Updated the
4943 protocol specs accordingly.
4945 Added support to the CMODE command in the client to set the
4946 founder auth data. Read the README to see how to set it.
4948 Added support to the CUMODE command to claim the founder
4949 rights. Read the README to see how to do it.
4951 Added support for the founder authentication to the Channel
4952 Entry in the server. Affected file silcd/idlist.h.
4954 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4955 server's CMODE command. Affected file silcd/command.c.
4957 * Added the following new functions into lib/silccore/silcauth.[ch]:
4958 silc_auth_get_method and silc_auth_get_data.
4960 * The server now saves the remote hosts public key to the
4961 SilcIDListData pointer. Affected file silcd/protocol.c.
4963 * The normal server now does not remove the channel entry from
4964 the cache if the founder authentication data is set. It used
4965 to remove it if the founder was the last one on the channel on
4966 the server and left the channel. The auth data is saved and
4967 if the channel is re-joined later the old entry is used with
4968 the old auth data. Affected files silcd/command_reply.c and
4971 * Removed the `pkcs' field from the SilcIDListData structure
4972 in the server; it is not used. Affected file silcd/idlist.h.
4974 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Fixed packet processing on slow links. Partial packets were
4977 never re-processed because the incoming data buffer was cleared
4978 by the application. Application must not directly clear the
4979 sock->inbuf, the packet processing routines handle it. Fixed
4980 this in client library and in server.
4982 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Fixed the WHOIS and IDENTIFY send reply function to really
4985 check whether to send list or just one entry. Affected file
4988 * Cleaned up the LEAVE command's channel key distribution. The
4989 affected file silcd/command.c.
4991 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4992 can enforce the channel mode as well. In that case the ID
4993 includes the ID of the server. The code now enforces the
4994 mode change if the router have different mode than the server.
4996 * The notify client operation with CMODE_CHANGE notify can now
4997 return NULL client_entry pointer if the CMODE was not changed
4998 by client. Application must check for this.
5000 * Added <Server ID> argument to INFO command to support server
5001 info fetching by Server ID.
5003 * Added silc_server_announce_get_channel_users to get assembled
5004 packets of channel users of the specified channel. Affected
5005 file silcd/server.[ch].
5007 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5008 was freed underneath the ID Cache.
5010 * Re-announce clients when the server received CHANNEL_CHANGE
5011 notify from the router. Affected file silcd/packet_send.c.
5013 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5016 crashed since it did not handle the fact that there is no cipher
5017 called "3" and didn't check the error condition. Now fixed.
5019 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5020 flag. It can be used to send message requests.
5022 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Implemented the RESTART command in the client.
5026 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5027 notice type messages. Added notice printing to the user
5030 * The channel keys are not re-generated if the channel's mode
5031 is PRIVKEY, ie private key on the channel exists. Affected
5032 files silcd/server.c and silcd/command.c.
5034 * Fixed a little bug in channel message delivery when channel
5035 private keys are set in the server. Affected file is
5036 silcd/packet_send.c.
5038 * Changed the setting on channel->on_channel = TRUE from the
5039 silc_client_save_channel_key to the JOIN command reply. The
5040 key payload is not received if the private channel key is set.
5041 Affected file lib/silcclient/command_reply.c and the
5042 lib/silcclient/client_channel.c.
5044 * When the CMODE_CHANGE notify is sent and the channel private
5045 key mode is removed the channel key must be re-generated in
5046 other cells as well. Added this support for the router in the
5047 silcd/packet_receive.c.
5049 * Added new local command NOTICE to send notice message on
5050 channel. Affected file silc/local_command.[ch].
5052 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Added new local command ME to the client. It is used to send
5055 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5056 some action. Affected file silc/local_command.[ch].
5058 * Changed channel_message and private_message client operations
5059 to deliver the message flags to the application. Added also
5060 the `flags' arguments to the silc_client_send_channel_message
5061 and silc_client_send_private_message functions. Affected file
5064 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Redefined the Private Message Payload to support private message
5067 keys and to support the new private message flags. Updated
5068 the protocol specs. Flags makes it possible to have for example
5069 CTCP style messages.
5071 * Added new type SilcPrivateMessagePayload and defined an API
5072 for it in the lib/silcclient/silcprivate.[ch].
5074 * Tested private message private keys successfully. Tested the
5075 private message key set, unset and list commands with the new
5078 * Redefined the Channel Message Payload to include the channel
5079 message flags (equal with private message flags) to support
5080 for example CTCP style messages.
5082 * Defined some of the message (for channel and private message)
5083 flags. Updated the protocol specs and added the flags to the
5084 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5086 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Added SilcKeyAgreementStatus type to the key agreement routines
5089 to indicate the current status and error if one occured.
5090 The status types are defined in the lib/silcclient/silcapi.h.
5092 * Added new local command KEY that is used to set and unset private
5093 keys for channels, set and unset private keys for private messages
5094 with remote clients and to send key agreement requests and
5095 negotiate the key agreement protocol with remote client. The
5096 key agreement is supported only to negotiate private message keys,
5097 it currently cannot be used to negotiate private keys for channels,
5098 as it is not convenient for that purpose.
5100 * Fixed a minor pending callback setting bug in the function
5101 silc_client_get_client_by_id_resolve, now the function works.
5102 Affected file lib/silcclient/idlist.c.
5104 * Added function silc_net_get_local_port to get local bound
5105 port by socket. Added to lib/silcutil/silcnet.[ch].
5107 * Added `sockets' and `sockets_count' fields to the SilcClient
5108 object. They hold the sockets of the listenning sockets in
5109 the client. Listenning sockets may be for example the key
5110 agreement server. Affected file lib/silcclient/client.[ch].
5111 Added functions the silc_client_add_socket and the
5112 silc_client_del_socket. They are exported to the application
5115 * Added ~./silc/clientkeys to support other client's public keys.
5117 * Renamed verify_server_key client operation to verify_public_key
5118 and added one argument to indicate the type of the connection
5119 (server, client etc.).
5121 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5123 * Added silc_server_connection_auth_request to handle the
5124 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5125 silcd/packet_receive.[ch].
5127 * Added silc_server_send_connection_auth_request into the
5128 silcd/packet_send.c to send the connection auth request packet.
5130 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5133 * Fixed the public key authentication in responder side in the
5134 server. The `auth_data' pointer includes the SilcPublicKey
5135 not the path to the public key. Affected file silcd/protocol.c.
5137 * Implemented the public key authentication in the initiator side
5138 in the server. Affected file silcd/protocol.c.
5140 * Removed the [RedirectClient] config section from the server
5141 configuration. Is not needed and I don't want to implement it.
5143 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Cleaned up the CMODE command in the server. It now works
5146 correctly and supports all the modes defined in the protocol.
5147 Affected file is silcd/command.c.
5149 * Added `hmac_name' field to the SilcChannelEntry in the server
5150 to hold the default HMAC of the channel. It can be set when
5151 creating the channel (with JOIN command). Affected files
5154 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5155 type to indicate the change of the current cipher and hmac
5156 on the channel. Client can safely ignore the <cipher> argument
5157 (if it chooses to do so) since the CHANNEL_KEY packet will
5158 force the channel key change anyway. The <hmac> argument is
5159 important since the client is responsible of setting the new
5160 HMAC and the hmac key into use.
5162 * Fixed the CMODE command in the client library as well.
5164 * Tested CMODE command in router environment successfully.
5166 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Show the version of the remote client (or server) when connecting
5169 to the server. It is logged to the log file. Affected file
5170 is silcd/protocol.c.
5172 * Fixed the KILLED notify handling in the client library. The
5173 client must be removed from all channels when receiving the
5176 Also, do not remove the client entry when giving the KILL
5177 command but when the KILLED notify is received.
5179 * Removed silc_idlist_find_client_by_nickname from the server.
5180 Not needed anymore. Affected files silcd/idlist.[ch].
5182 * Implemented the CHANNEL_CHANGE notify type handling to the
5183 server. Affected file silcd/server.c.
5187 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added silc_server_send_notify_invite to send the INVITE
5190 notify between routers.
5192 * Implemented the INVITE command correctly to the server.
5194 * Implemented the INVITE notify type handling in the server.
5196 * Implemented the INVITE command to the client library and on the
5199 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Added function silc_server_get_client_resolve to find the
5202 client entry by ID from all ID lists and then resolve it
5203 (using WHOIS) if it cannot be found. Affected file is
5206 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Implemented the BAN command to the client library.
5210 * The JOIN command in the server now checks the invite list
5213 * Changed the silc_command_reply_payload_encode_va and the
5214 silc_command_payload_encode_va to support that if argument is
5215 NULL it ignores and checks the next argument. Affected file
5216 lib/silccore/silccommand.c.
5218 * Added silc_server_send_notify_ban to send the BAN notify
5219 type between routers.
5221 * Chaned the silc_notify_payload_encode to support that if
5222 argument is NULL it ignores and checks the next argument.
5223 Affected file lib/silccore/silcnotify.c.
5225 * Tested ban lists in router environment successfully.
5227 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Implemented BAN command to the server, in silcd/command.[ch].
5231 * Removed the BAN and INVITE_LIST modes from the CMODE command
5234 * Added function silc_string_match to regex match two strings.
5235 Affected files lib/silcutil/silcutil.[ch].
5237 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Redefined parts of the SilcChannelEntry in the server to support
5240 the new ban and invite lists.
5242 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Redefined the INVITE command. The same command can be used to
5245 invite individuals to the channel but also to manage the invite
5246 list of the channel (to add to and remove from the invite list).
5247 Updated the protocol specs.
5249 * Added new command SILC_COMMAND_BAN that can be used to manage
5250 the ban list of the channel. Updated the protocol specs.
5252 * Removed the channel modes: the SILC_CMODE_BAN and the
5253 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5254 in the CMODE command. The equivalent features are now available
5255 using INVITE and BAN commands. Updated the protocol specs.
5257 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5258 in the network about change in the current ban list. The notify
5259 type is not used by the client.
5261 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5262 support the invite lists.
5264 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Added new function silc_string_regexify that converts string
5267 including wildcard characters into regex string that can
5268 be used by the GNU regex library. Added into the file
5269 lib/silcutil/silcutil.[ch].
5271 Added silc_string_regex_combine to combine to regex strings
5272 into one so that they can be used as one regex string by
5273 the GNU regex library. Added into the file
5274 lib/silcutil/silcutil.[ch].
5276 Added silc_string_regex_match to match two strings. It returns
5277 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5279 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Imported GNU regex to the soruce tree into lib/contrib.
5282 Fixed some compiler warning from the regex.c.
5284 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Fixed MOTD command in the server to work in router environment.
5288 * Fixed the MOTD command in the client library to support
5289 the server argument in the command.
5291 * Added `nickname_len' argument to the silc_idlist_add_client
5292 in the server, as the `nickname' argument may be binary data
5295 * Added silc_idlist_get_channels to return all channels from
5298 * Implemented LIST command to the server. Affected file is
5301 * Implemented the LIST command to the client library and on the
5304 * Added [<user count>] argument to the LIST command reply.
5305 With private channels the user count is not shown.
5307 * Updated TODO and README.
5309 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * The client entry's data.registered must be TRUE even with
5312 global client entry on global client list. The data.registered
5313 is used to check whether the client is anymore in the network,
5314 for example with WHOWAS command so it must be valid.
5316 * Fixed the WHOWAS command in the server. It now actually works
5317 in router environment. Added function into silcd/command_reply.c
5318 silc_server_command_reply_whowas_save.
5320 * Added silc_idlist_purge function to the silcd/idlist.c
5321 to periodically purge the ID Cache.
5323 * Fixed INFO command in the server. It works now in router
5324 environment. Added <server name> argument to the INFO command
5325 reply. Updated the protocol specs.
5327 * Fixed minor bug in silc_idcache_purge to not purge if the
5328 expire value is zero.
5330 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5331 they were buggy because of the WHOWAS information.
5333 * Fixed local command MSG to handle the async resolving of
5334 the remote client properly. It used to fail the first MSG.
5335 Affected file silc/local_command.c.
5337 * Added `data_len' field to SilcIDCache context.
5339 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Update TODO. Todo in commands in the server.
5343 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5346 used by routers as broadcast packet to inform other routers
5347 about the changed user mode.
5349 Implemented the notify handling in the server. Affected file is
5350 silcd/packet_receive.c. Added the function
5351 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5353 * Added new generic Channel Payload and deprecated the New Channel
5354 Payload. The New Channel Payload is now the generic Channel
5357 * Added new argument `mode' to the silc_server_send_new_channel
5358 as it is required in the Channel Payload now.
5360 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5361 and created a new and real SilChannelPayload to represent the
5362 new generic Channel Payload. Implemented the encode/decode
5363 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5365 * Added silc_server_get_client_channel_list to return the list
5366 of channels the client has joined for WHOIS command reply.
5367 Affected file silcd/server.[ch].
5369 * Implemented the channel list sending in the WHOIS command reply
5370 in server and in the client.
5372 Implemented the channel list displaying on the user interface
5373 as well. Affected file silc/client_ops.c.
5375 * Added silc_channel_payload_parse_list to parse list of Channel
5376 Payloads. It returns SilcDList list of SilcChannelPayloads.
5377 Client for example can use this function to parse the list of
5378 channels it receives in the WHOIS command reply. The caller
5379 must free the list by calling silc_channel_payload_list_free.
5380 Affected files lib/silccore/silcchannel.[ch].
5382 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Added one new argument <user mode> to the WHOIS command reply
5385 to return the mode of the user in SILC. Updated the protocol
5388 Implemented it to the server and client.
5390 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Fixed the mode printing on the user interface on joining.
5393 Affected file silc/client_ops.c.
5395 * Implemented the UMODE command and user modes in general to the
5396 client library and to the user interface.
5398 * Implemented the UMODE command to the server.
5400 * The server now sends UNKNOWN_COMMAND error status if client sends
5401 unknown command. Affected file silcd/command.c.
5403 * All server commands now handle the command identifier the right
5404 way when sending the command reply to the client. The client can
5405 use to identify the command replies with the identifier.
5407 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Added silc_server_get_client_route to resolve the route to
5410 the client indicated by the client ID. Affected file is
5413 * Added silc_server_relay_packet as general function to relay
5414 packet to arbitrary destination. This deprecates functions
5415 like _send_private_message_key, _relay_notify etc. Affected
5416 file is silcd/packet_send.[ch].
5418 Removed silc_server_send_key_agreement,
5419 silc_server_send_private_message_key and
5420 silc_server_packet_relay_notify functions from the file
5421 silcd/packet_send.[ch].
5425 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5426 server. Affected file silcd/packet_receive.[ch].
5428 * Implemented the KILL command to the client. Implemented the
5429 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5430 Affected files lib/silcclient/command[_reply].c and
5431 lib/silcclient/client_notify.c. Implemented the KILL notify
5432 printing in the user inteface.
5434 * Fixed a lot silc_parse_nick memory leaks from the client
5435 library in the file lib/silcclient/command.c.
5437 * Changed the silc_server_send_notify_on_channels's `sender'
5438 argument from SilcSocketConnection to SilcClientEntry to
5439 check the sender as entry and not as connection object and not
5440 to send to the client provided as argument. The affected file
5441 is silcd/packet_send.[ch].
5443 * The notify packets that are destined directly to the client used
5444 to not to be processed by the server. Now changed that and the
5445 server processes all notify packets. After relaying the packet
5446 to the client the notify packet is processed in the server.
5448 * The silc_server_free_client_data now checks whether there is
5449 pending outgoing traffic for the client and purges the data to
5450 the network before removing the client entry.
5452 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5455 an client is killed from the SILC Network. Updated the protocol
5458 Added new function silc_server_send_notify_killed to the
5459 silcd/packet_send.[ch].
5461 * Added function silc_server_packet_relay_notify to relay notify
5462 packets that are destined directly to a client. In this case
5463 the server does not process the notify packets but merely relays
5464 it to the client. Affected file silcd/packet_send.[ch].
5466 Added also silc_server_packet_process_relay_notify to check
5467 whereto relay the notify. Affected file is
5468 silcd/packet_receive.[ch].
5470 * Implemented the KILL command to the server.
5474 * Added the backup schema desgined last fall to the protocol
5475 specs for everyone to see. The specification is in the
5476 *-spec-xx.txt draft and the packet type definitions for the
5477 backup routers is in *-pp-xx.txt draft. Thusly, added also
5478 new packet type SILC_PACKET_CELL_ROUTERS.
5480 * A big security problem in the implementation discovered. The
5481 signoff of an client did not cause new channel key generation
5482 which it of course should've done. The channel keys must be
5483 always re-generated when client leaves (or signoffs) the channel.
5484 The silc_server_remove_from_channels funtion now handles
5485 the channel key re-generation.
5487 * Added `sender' argument to the silc_server_send_notify_on_channels
5488 to not to send the client provided as argument. Affected file
5489 silcd/packet_send.[ch].
5491 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Implemented OPER and SILCOPER commands into the server and
5496 * Added silc_auth_verify and silc_auth_verify_data to verify
5497 the authentication directly from the authentication payload.
5498 It supports verifying both passphrase and public key based
5499 authentication. Affected file lib/silccore/silcauth.[ch].
5501 * Added `hash' field to the SilcIDListData structure. It is the
5502 hash negotiated in the SKE protocol. Affected file is
5505 * Slight redesigning of the SilcAuthPayload handling routines.
5506 Do not send SilcPKCS but SilcPublicKey as argument.
5508 * Implemented the public key authentication support to the
5509 serverconfig. The public key is loaded from the provided path
5510 and saved as authentication data to void * pointer. Thus,
5511 changed the unsigned char *auth_data to void *auth_data;
5513 * Fixed SHUTDOWN command to send the reply before the server
5514 is shutdown. :) Affected file silcd/command.c.
5516 * Fixed fatal bug in CONNECT command. The hostname was invalid
5517 memory and server crashed. Affected file silcd/command.c.
5519 * Fixed fatal bug in CLOSE command. The server_entry became
5520 invalid but was referenced later in the command. Affected file
5523 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Fixed fatal bug in failure packet handling. Server ignored
5526 the failure and thus crashed when it came.
5530 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5533 that the command may be executed only once in (about) 2 seconds.
5534 The old SILC_CF_LAG flag is same but allows command bursts up
5535 to five before limiting.
5537 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5538 server code. Various commands now includes the CF_LAG_STRICT
5539 flag to disallow any kind of miss-use of the command.
5541 * Fixed the silc_buffer_unformat to not to allocate any data
5542 if the length of the data is zero. It used to allocate the
5543 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5545 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Changed the format of AdminConnection configuration section
5548 in the server. Added username of the admin to the format.
5549 Affected files silcd/serverconfig.[ch].
5551 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5552 to return admin configuration data by host, username and/or
5555 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Implemented WHOWAS command to the server. Added the functions:
5559 silc_server_command_whowas_parse,
5560 silc_server_command_whowas_send_reply,
5561 silc_server_command_whowas_from_client and
5562 silc_server_command_whowas_from_server
5564 * Added <Client ID> argument to the WHOWAS command reply. Updated
5565 the protocol specs accordingly.
5567 * Implemented WHOWAS command and command_reply to the client
5570 Implemented the WHOWAS printing on the user interface.
5572 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Added new argument to the WHOWAS command reply, the real name.
5575 It is an optional argument. Updated the protocol specs.
5577 * Added SilcIDCacheDestructor callback that is registered when
5578 the SilcIDCache is allocated. The callback is called when
5579 an cache entry in the ID Cache expires, or is purged from the
5580 cache. Added into lib/silccore/idcache.[ch].
5582 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5583 to destruct the client entries when the cache entry expires.
5584 Other ID Cache's in server and in the client library ignores
5587 * If the ID Cache entry's `expire' field is zero then the entry
5588 never expires. Added boolean `expire' argument to the
5589 silc_idcache_add function in the lib/silccore/idcache.[ch].
5590 If it is TRUE the default expiry value is used.
5592 * Added silc_server_free_client_data_timeout that is registered
5593 when client disconnects. By default for 5 minutes we preserve
5594 the client entry for history - for WHOWAS command.
5596 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added support to the server to enforce that commands are not
5599 executed more than once in 2 seconds. If server receives
5600 commands from client more frequently, timeout is registered
5601 to process the commands. Affected file silcd/command.c.
5602 Added new function silc_server_command_process_timeout.
5604 * Changed NICK_NOTIFY handling in client library to check that
5605 if the client's nickname was changed, so there is no need to
5606 resolve anything from the server.
5608 * Removed error printing from the WHOIS and IDENTIFY commands.
5609 If error occurs then it is ignored silently in the client library.
5610 The application, however, may map the received error to
5611 human readable error string. The application currently maps
5612 the NO_SUCH_NICKNAME error to string.
5614 * Made the command status message public to the application. Moved
5615 them from lib/silcclient/command_reply.c to
5616 lib/silcclient/command_reply.h. The application can map the
5617 received command status to the string with the
5618 silc_client_command_status_message function.
5620 * Added check to the server to check that client's ID is same
5621 as the Source ID in the packet the client sent. They must
5624 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added dist-bzip hook to the Makefile.am to make bzip2
5627 compressed distributions.
5629 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Server now enforces the maximum length for the nickname and
5632 the channel as protocol specification dictates. 128 bytes for
5633 nickname and 256 bytes for channel name.
5635 * Moved the WHOIS printing to the application. The client libary
5636 does not print out the WHOIS information anymore, the application
5637 must do it. Renamed silc_client_command_reply_whois_print to
5638 the silc_client_command_reply_whois_save.
5640 The client's idle time is also sent to the application now, and
5641 the idle is shown on screen.
5643 * Added silc_client_command_reply_identify_save to save the
5644 received IDENTIFY entries.
5646 * Do not check for channel private keys in message sending and
5647 reception if the channel does not have the PRIVKEY mode set.
5648 Affected file lib/silclient/client_channel.c.
5650 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5653 just surfaced after chaning the JOIN procedure.
5655 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Added silc_client_get_clients_by_list to get client entries
5658 from Client ID list, that is returned for example by JOIN
5659 and USERS command replies. The application should use this
5660 function for example when JOIN command reply is received to
5661 resolve the clients already on the channel (library does not
5662 do that anymore as USERS command reply is not used in the JOIN
5663 procedure anymore). Affected files lib/silcclient/silcapi.h and
5664 lib/silcclient/idlist.c.
5666 * JOIN command reply and USERS command reply returns now SilcBuffer
5667 pointers instead of unsigned char pointers when returning
5668 the client list and mode list.
5670 * Added <Client ID> argument to the JOIN command reply, mainly
5671 for the server to identify for which client the command was
5672 originally sent. Updated protocol specs accordingly.
5674 * Added SilcDlist private_key pointer to the SilcChannelEntry
5675 in the client to support the channel private keys. Affected
5676 file is lib/silcclient/idlist.h.
5678 * Added SilcChannelPrivateKey argument to the function
5679 silc_client_send_channel_message so that application can choose
5680 to use specific private ke if it wants to. If it is not provided,
5681 the normal channel key is used, unless private keys are set.
5682 In this case the first (key that was added first) is used
5683 as the encryption key.
5685 * Implemented the support for channel private key handling.
5686 Implemented the following functions:
5688 silc_client_add_channel_private_key,
5689 silc_client_del_channel_private_keys,
5690 silc_client_del_channel_private_key,
5691 silc_client_list_channel_private_keys and
5692 silc_client_free_channel_private_keys
5694 Affected file lib/silcclient/client_channel.c.
5696 * Added the support for the private keys in the channel message
5697 sending and encryption and in the message reception and
5698 decryption. Affected funtions are
5699 silc_client_send_channel_message and silc_client_channel_message.
5701 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Added SKE's key verify callback to the client library's
5704 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5706 * Removed the statement that server (or router) must send USERS
5707 command reply when joining to the channel so that the client
5708 knows who are on the channel. Instead, the client list and
5709 client's mode list is now sent in the JOIN command reply to the
5710 client who joined channel. This is better solution.
5712 * Added function silc_server_get_users_on_channel and function
5713 silc_server_save_users_on_channel to the silcd/server.[ch].
5715 * Removed function silc_server_command_send_users from the
5718 * Do not show topic on the client library anymore. The topic is
5719 sent in the command reply notify to the application and the
5720 application must show the topic now.
5722 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Added client searching by nickname hash into the IDENTIFY and
5725 WHOIS commands in the server as they were clearly missing from
5726 them. Affected file is silcd/command.c.
5728 * Fixed a bug in private message receiving in the client library.
5729 The remote ID was freed and it wasn't supposed, now it is
5732 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Minor fix to the channel payload; allocate the data area, as it
5735 needs to be of specific length.
5737 * If the key agreement port is zero then the operating
5738 system will define the bound port. Affected files are
5739 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5741 * Added new function silc_channel_payload_decrypt into the file
5742 lib/silccore/silcchannel.[ch].
5744 * Moved the channel message etc, check from silc_packet_decrypt
5745 to applications. The library calls now a generic
5746 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5747 when the packet is either normal or special. This was done to
5748 allow more wide range of checking that was not allowed when
5749 the code was in library. Now applications can do virtually any
5750 checks to the packet and return to the library the decision how
5751 the packet should be processed. Affected files are
5752 lib/silccore/silcpacket.[ch].
5754 Added silc_server_packet_decrypt_check to the server and
5755 silc_client_packet_decrypt_check to the client library.
5757 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5758 to send with specified source and destination information.
5760 * Channel message delivery between routers was broken after the
5761 channel key distribution was fixed earlier. The channel key
5762 was used be to distributed to other routers as well which is not
5763 allowed by the protocol. Now this is fixed and channel keys
5764 really are cell specific and the channel message delivery between
5765 routers comply with the protocol specification.
5767 * Fixed various commands in server to check also the global list
5768 for the channel entry and not just the local list. The affected
5769 file silcd/command.c.
5771 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Added assert()s to buffer formatting and unformatting routines
5774 to assert (if --enable-debug) when error occurs. Affected
5775 file: lib/silcutil/silcbuffmt.c.
5777 * Changed to auto-reconnect to check whether the remote host is
5778 router and register the re-connect timeout if it is. It used
5779 to check that whether we are normal server, but router must do
5780 auto-reconnect with another router as well. Affected file
5783 * Removed the [<key len>] option from CMODE command as the cipher
5784 name decides the key length, nowadays. See the defined ciphers
5785 from the protocol specification.
5787 * Added [<hmac>] option to the CMODE command to define the HMAC
5788 for the channel. Added SILC_CMODE_HMAC channel mode.
5790 * Added [<hmac>] option for the JOIN command so that user can
5791 select which HMAC is used to compute the MACs of the channel
5794 * Added Hmac field to the Channel Message Payload. The integrity
5795 of plaintext channel messages are now protected by computing
5796 MAC of the message and attaching the MAC to the payload. The
5797 MAC is encrypted. Now, it is clear that this causes some
5798 overhead to the size of the packet but rationale for this is that
5799 now the receiver can verify whether the channel message decrypted
5800 correctly and also when private keys are set for the channel the
5801 receiver can decrypt the packet with several keys and check from
5802 the MAC which key decrypted the message correctly.
5804 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5805 lib/silccrypt/silccipher.[ch].
5807 * Added silc_hash_len to return the digest length into the
5808 lib/silcrypt/silchash.[ch].
5810 * Rewrote parts of Silc Channel Payload interface in the
5811 lib/silccore/silcchannel.[ch]. The encode function now also
5812 encrypts the packet and parse function decrypts it.
5814 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Fixed a minor formatting bug in the SKE's key material processing.
5817 It actually might have processed the keys wrong way resulting
5820 * Redefined the mandatory HMAC algorithms and added new algorithms.
5821 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5822 and hmac-md5 truncated to 96 bits. The mandatory is now
5823 hmac-sha1-96. Rest are optional (including the one that used
5824 to be mandatory). Rationale for this is that the truncated HMAC
5825 length is sufficient from security point of view and can actually
5826 make the attack against the HMAC harder. Also, the truncated
5827 HMAC causes less overhead to the packets. See the RFC2104 for
5830 * Added new [hmac] configuration section. The SKE used to use
5831 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5832 is of course wrong. The official names that must be proposed in
5833 the SKE are the ones defined in the protocol specification
5834 (hmac-sha1-96 for example). The user can configure any hmac
5835 using any hash function configured in the [hash] section. At
5836 least, the mandatory must be configured.
5838 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5840 * Added HMAC list to the SKE proposal list. It has now both
5841 hash algorithm list and HMAC list. This makes the protocol
5842 incompatible with previous versions. The SKE now seems to work
5843 the way it is supposed to work, for the first time actually.
5845 * Defined plain Hash algorithms to the protocol specification.
5848 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Implemented support for key agreement packets into the server.
5851 Added functions silc_server_key_agreement and
5852 silc_server_send_key_agreement. Other than these functions,
5853 server has nothing to do with this packet.
5855 * Added support for private message key packets into the server.
5856 Added functions silc_server_private_message_key and
5857 silc_server_send_private_message_key.
5861 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5862 called in the protocol's final callback instead in the END
5863 protocol state. This makes a little more sense and in the same
5864 time in client we can use the same protocol routines for normal
5865 key exchange and to key agreement packet handling as well.
5867 * Added to both client's and server's KE protocol context the
5868 SilcSKEKeyMaterial pointer to save the key material. We will
5869 bring the key material to the protocol's final callback by doing
5870 this. The final callback must free the key material.
5872 * Added SKE's packet_send callback into client's KE protocol
5873 context so that the caller can choose what packet sending function
5874 is used. This way we can use different packet sending when
5875 doing normal SKE when doing key agreement packet handling (in
5876 the key agreement packet handling we do not want to encrypt
5879 * Implemented the responder side of the key agreement routines
5880 in the client. The client can now bind to specified port and
5881 accept incoming key negotiation. The key material is passed
5882 to the application after the protocol is over.
5884 * Implemented the processing of incoming Key Agreement packet
5885 in the client. Added function silc_client_key_agreement to
5888 * Implemented the intiator side of the key agreement routines
5889 in the client. The client can now initiate key agreement with
5890 another remote client. The key material is passed to the
5891 application after the protocol is over.
5893 * Created client_keyagr.c to include all the key agreement
5896 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5897 SILC_TASK_CALLBACK except that it is not static.
5899 * Created client_notify.c and moved the Notify packet handling
5900 from the client.[ch] into that file.
5902 * Created client_prvmsg.c and moved all private message and
5903 private message key routines from the client.[ch] into that file.
5905 * Create client_channel.c and moved all channel message and
5906 channel private key routines from the client.[ch] into that file.
5908 * Changed silc_client_get_client_by_id_resolve to resolve with
5909 WHOIS command instead of IDENTIFY command, in the file
5910 lib/silclient/idlist.c.
5912 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Implemented the SKE's responder side to the Client library.
5916 * When FAILURE is received to the protocol do not trust it
5917 blindly. Register a timeout to wait whether the remote closes
5918 the connection as it should do it, only after that process the
5919 actual failure. This was changed to both client and server.
5921 * Added client_internal.h to include some of the structures
5922 there instead of client.h in lib/silcclient/.
5924 * Added function silc_task_unregister_by_callback to unregister
5925 timeouts by the callback function.
5927 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Some "Incomplete WHOIS info" errors has been appearing on the
5930 log files. Took away the entry->userinfo check from WHOIS
5931 reply sending. The entry->userinfo is now " " if client did not
5932 provide one. I thought this was fixed earlier but something
5933 is wrong still. Let's see if the error still appears.
5935 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Fixed a minor bug in the login when the channel key is
5938 re-generated in the server. It used to generate the key in
5939 wrong order and thus caused problems in the channel traffic.
5941 * Fixed a minor bug in channel key distsribution after
5942 KICK command. The key was not sent to the router even though
5945 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Added silc_ske_process_key_material_data as generic routine
5948 to process any key material as the SILC protocol dictates. The
5949 function is used by the actual SKE library but can be used by
5950 applications as well. This relates to the private message keys
5951 and the channel private keys since they must be processed the
5952 same way the normal SILC session keys. The protocol dictates
5953 this. Affected files: lib/silcske/silcske.[ch].
5955 Added also silc_ske_free_key_material to free the
5956 SilcSKEKeyMaterial structure.
5958 * Defined silc_cipher_set_key function to set the key for
5959 cipher without using the object's method function. The affected
5960 files: lib/silccrypt/silccipher.[ch].
5962 * Implemented silc silc_client_add_private_message_key,
5963 silc_client_add_private_message_key_ske,
5964 silc_client_del_private_message_key,
5965 silc_client_list_private_message_keys and
5966 silc_client_free_private_message_keys functions in the
5969 Added functions silc_client_send_private_message_key to send
5970 the Private Message Key payload and silc_client_private_message_key
5971 to handle incoming Private Message Key payload.
5973 * Added Cipher field to the Private Message Key payload to set
5974 the cipher to be used. If ignored, the default cipher defined
5975 in the SILC protocol (aes-256-cbc) is used.
5977 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Removed lib/silcclient/ops.h file.
5981 Redefined parts of the SILC Client Library API. Created new
5982 file silcapi.h that deprecates the ops.h file and defines the
5983 published Client Library API. Defined also private message key
5984 API and channel private key API into the file.
5986 This is the file that the application must include from the
5987 SILC Client Library. Other files need not be included by
5988 the application anymore.
5990 * Added new key_agreement client operation callback and also
5991 defined the Key Agreement library API for the application.
5993 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5996 is used by clients to request key negotiation between another
5997 client in the SILC network. If the negotiation is started it
5998 is performed using the SKE protocol. The result of the
5999 negotiation, the secret key material, can be used for example
6000 as private message key.
6002 Implemented the Key Agreement payload into the files
6003 lib/silccore/silauth.[ch].
6005 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Redefined ciphers for the SILC protocol. Added some new ciphers
6008 and defined the key lengths for the algorithms. Changed the
6009 code accordingly. The default key length is now 256 bits.
6011 * Fixed SKE key distribution function silc_ske_process_key_material
6012 when the key length is more than 128 bits. The default key
6013 length in SILC is now 256 bits.
6015 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6016 to indicate unsupported algorithm.
6018 * Renamed rijndael.c to aes.c and all functions as well.
6020 * Fixed a long standing channel key setting bug in client library.
6021 Weird that it has never surfaced before.
6023 * Fixed bug in channel deletion. If the entire channel is removed
6024 then it must also delete the references of the channel entry
6025 from the client's channel list as the client's channel entry and
6026 the channel's client entry share same memory.
6028 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Implemented CONNECT and SHUTDOWN commands in the client.
6032 * Implemented CLOSE command to the client.
6034 * Added the function silc_idlist_find_server_by_name into the
6035 files silcd/idlist.[ch].
6037 Added the function silc_idlist_find_server_by_conn into the
6038 files silcd/idlist.[ch].
6040 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * DIE command was renamed to SHUTDOWN. Updated the both code
6045 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6046 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6048 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6051 * Added function silc_server_create_connection function to create
6052 connection to remote router. My server implementation actually
6053 does not allow router to connect to normal server (it expects
6054 that normal server always initiates the connection to the router)
6055 so the CONNECT command is only good for connecting to another
6058 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6061 or some other client was kicked from the channel.
6063 Implemented the handling of the notify type to both client
6066 Implemented silc_server_send_notify_kicked to send the KICKED
6067 notify. It is used to send it to the server's primary router.
6069 * Implemented the KICK command into server and client.
6071 * Added `query' argument to the silc_idlist_get_client function
6072 to indicate whether to query the client from server or not if
6075 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6076 to indicate that the client is not channel founder.
6080 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Removed the rng context from SilcPacketContext structure and
6083 changed that the packet routine uses the Global RNG API.
6085 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Added support for quit message that client can "leave" on the
6088 channel when it quits the SILC. It is ditributed inside the
6089 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6091 Added silc_server_free_client_data that will take the
6092 signoff message as argument.
6094 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6096 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Updated parts of the protocol specification to keep it up
6101 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6104 payloads in one packet.
6106 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6107 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6108 use now the new List flag.
6110 * Also deprecated the following packet types: REPLACE_ID,
6111 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6113 * Added list support for Notify packet in server.
6115 * Added silc_server_send_notify_channel_change to send the
6116 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6117 the silc_server_send_replace_id.
6119 * Added silc_server_send_notify_nick_change to send the
6120 NICK_CHANGE notify type. Deprecates the function
6121 silc_server_send_replace_id.
6123 * Added silc_server_send_notify_join to send the JOIN notify type.
6124 Deprecates the function silc_server_send_new_channel_user.
6126 * Added silc_server_send_notify_leave to send LEAVE notify type.
6127 Deprecates the function silc_server_send_remove_channel_user.
6129 * Added silc_server_send_notify_cmode and
6130 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6131 types. Deprecates the silc_server_send_set_mode function.
6133 * Added SERVER_SIGNOFF notify type to indicate that server has
6134 quit. This means that all clients on the channel from that
6135 server will drop. This can be also used when netsplit happens.
6137 Deprecated REMOVE_ID packet type since it is not needed anymore
6140 Added silc_server_send_notify_server_signoff to send the
6141 SERVER_SIGNOFF notify type. Deprecates the function
6142 silc_server_send_remove_id.
6144 Added also silc_server_send_notify_signoff to send the
6145 SIGNOFF notify type.
6147 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6148 SILC protocol from this day on. Changed the protocol
6149 specification as well.
6151 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6152 notify type. It is used between routers to notify about
6153 topic changes on a channel.
6155 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6158 * Partly updated the protocol specification to comply with the
6159 changes now made. It is still though a bit outdated.
6161 * The JOIN notify type now takes one extra argument <Channel ID>.
6162 The packet used to be destined to the channel but now the
6163 JOIN type may be sent as list thus it is impossible to
6164 destine it to any specific channel. By adding this argument
6165 it is again possible.
6167 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Added CREDITS file. The CHANGES and CREDITS file will appear
6170 in the distribution as well.
6172 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6175 types in the server's silcd/packet_receive.c.
6177 * Implemented CMODE and CUMODE to work in router environment.
6179 * Fixed minor encoding and decoding buglet from the
6180 lib/silccore/silcmode.c.
6182 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6185 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6187 * Changed all SilcConfigServer* and silc_config_server* to
6188 SilcServerConfig* and silc_server_config*, respectively.
6191 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Associated the ID (client or server ID) to the Authentication
6194 Payload to avoid any possibility of forging. Updated the
6195 protocol specification and the code accordingly.
6197 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * The RSA key length is now save to the RsaKey context in the
6200 key generation process in lib/silccrypt/rsa.c. The key length
6201 is now used to figure out the maximum size of the block allowed
6202 to be encrypted/signed.
6204 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6205 is equivalent to the silc_mp_mp2bin but does not allocate any
6208 * Changed silc_mp_mp2bin API to take length argument. If it is
6209 non-zero then the buffer is allocated that large. If zero, then
6210 the size is approximated using silc_mp_sizeinbase, which however
6213 * Created Global RNG API which is global RNG that application can
6214 initialize. After initializing, any routine anywhere in the
6215 code (including library) can use RNG without allocating a new
6216 RNG object. This was done to allow this sort of use of the
6217 RNG in code that has no chance to allocate RNG object. All
6218 applications currently allocate this and many routines in the
6219 library use this. Affected file lib/silccrypt/silcrng.[ch].
6221 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6222 it to use the Global RNG API.
6224 * Defined Authentication Payload into protocol specification that
6225 is used during SILC session to authenticate entities. It is
6226 used for example by client to authenticate itself to the server
6227 to obtain server operator privileges.
6229 Implemented this payload into the lib/silccore/silcauth.[ch].
6230 Implemented also routines for public key based authentication
6231 as the new protocol specification dictates.
6233 Moved definitions of different authentication methods from
6234 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6236 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6237 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6238 silc_pkcs_verify_with_hash functions into the file
6239 lib/silccrypt/silcpkcs.[ch].
6241 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * The client entry's userinfo pointer must be always valid.
6244 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6245 will fail since it requires the userinfo. Now, the userinfo
6246 is allocated as "" if actual userinfo does not exist. Actually,
6247 it must exist and it is totally Ok to drop client connections
6248 that does not announce the userinfo. However, we will make
6249 this workaround for now.
6251 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6252 to return the remote port by socket.
6254 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6257 SILC_SERVER_PENDING_EXEC and added an new macro
6258 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6259 data or when error occurs while processing the pending command.
6261 Added new argument `destructor' into silc_server_command_pending
6262 and to the SilcServerCommandPending object. This destructor is
6263 now called after calling the pending callback or if error occurs
6264 immediately. If error occurs the actual pending callback won't
6265 be called at all - only the destructor. The destructor may be
6266 NULL if destructor is not needed.
6268 All this applies for client library code as well. Similar
6269 changes were made there as well for the pending commands.
6271 In the client, the application must now allocate the
6272 SilcClientCommandContext with the silc_client_command_alloc
6275 * Added reference counter to the SilcServerCommandContext. Added
6276 function silc_server_command_alloc and silc_server_command_dup
6279 Same type of functions added to the client library for the same
6282 * Removed the cmd_ident from IDListData away since it is now
6283 global for all connections. It is the command identifier used
6284 in command sending and with pending commands. The affected file
6287 * Added reference counter to the SilcSocketConnection objecet to
6288 indicate the usage count of the object. The object won't be
6289 freed untill the reference counter hits zero. Currently only
6290 server uses this, and client ignores it. The client must be
6291 set to use this too later. The affected files are
6292 lib/silccore/silcsockconn.[ch]. Added also the function
6293 silc_socket_dup to increase the reference counter.
6295 This was mainly added because it is possible that the socket
6296 is removed underneath of pending command or other async
6297 operation. Now it won't be free'd and proper DISCONNECTING
6298 flags, etc. can be set to avoid sending data to connection that
6299 is not valid anymore.
6301 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6302 the connection. After that it sets SILC_SET_DISCONNECTED.
6303 It is, however, possible that the socket data is not still freed.
6304 The silc_server_packet_process now checks that data is not
6305 read or written to connection that is DISCONNECTED. The socket
6306 get's freed when the reference counter hits zero.
6308 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Changed the client operation API: channel_message operation's
6311 `sender' is now the client entry of the sender, not the nickname
6312 and the `channel' is the channel entry, not the channel name.
6314 In the private_message operation the `sender' is now also the
6315 client entry of the sender not the nickname.
6317 Affected file is lib/silcclient/ops.h and all applications
6318 using the client operations.
6320 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * Moved the calling of ops->connect() from connect_to_server_final
6323 into receive_new_id functin since that is the point when the
6324 client is actually allowed to send traffic to network. The
6325 affected file is lib/silcclient/client.c.
6327 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6330 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6331 (if needs broadcasting) instead of broadcasting the packets one
6332 by one which would make a burst in the network traffic.
6334 * Added `broadcast' argument to the functions in silcd/server.[ch]
6335 silc_server_create_new_channel[_with_id] to indicate whether
6336 to send New Channel packet to primary router.
6338 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Added new function into the silcd/server.[ch] files:
6341 silc_server_create_new_channel_with_id to create new channel with
6342 already existing Channel ID.
6344 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6345 lib/silccore/silcpacket.h. This packet is used t send list of
6346 Set Mode payloads inside one packet. Server uses this to set
6347 the modes for the channels and clients on those channels, that it
6348 announced to the router when it connected to it. The protocol
6349 specification has been updated accordingly.
6351 * The silc_server_new_channel did not handle the packet coming
6352 from normal server as it normally does not send that. However,
6353 when it announces its channels it does send it. Implemented
6354 the support for that.
6356 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6357 into the file lib/silccore/id.h.
6359 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6361 * Fixed memory leaks in the functions silc_idlist_del_client,
6362 silc_idlist_del_channel and silc_idlist_del_server in the file
6363 silcd/idlist.c. All of those leaked like a sieve.
6365 * Fixed some small memory leaks in the client's function
6366 silc_client_notify_by_server.
6368 * Added functions into silcd/server.c: silc_server_announce_clients,
6369 silc_server_announce_channels and silc_server_announce_server.
6370 These functions are used by normal and router server to announce
6371 to its primary router about clients, channels and servers (when
6372 router) that we own. This is done after we've connected to the
6375 These functions effectively implements the following packet types:
6376 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6377 and SILC_PACKET_NEW_ID_LIST.
6379 * Added new functions into the silcd/packet_receive.[ch]:
6380 silc_server_new_id_list, silc_server_new_channel_list and
6381 silc_server_new_channel_user_list to handle the incoming
6382 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6384 * Added support of changing Channel ID in the function
6385 silc_server_replace_id. If the server that announces a channel
6386 to the router already exists in the router (with same name but
6387 with different Channel ID), router is responsible to send
6388 Replace ID packet to the server and force the server to change
6389 the Channel ID to the one router has.
6391 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6392 client that the Channel ID has been changed by the router. The
6393 normal server sends this to the client. Client must start using
6394 the new Channel ID as the channel's ID.
6396 Implemented handling of this new type into lib/silcclient/client.c
6397 into the function silc_client_notify_by_server.
6399 * Added new function silc_idlist_replace_channel_id into the files
6400 silcd/idlist.[ch] to replace the Channel ID.
6402 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Call silc_server_command_identify_check always when processing
6405 the IDENTIFY command in silcd/command.c
6407 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6410 send keepalive packets. The packet can be sent by clients,
6411 servers and routers.
6413 Added function silc_socket_set_heartbeat into the file
6414 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6415 If not set, the heartbeat is not performed. The actual
6416 heartbeat is implemented in the low level socket connection
6417 library. However, application is responsible of actually
6420 Added silc_server_send_heartbeat to send the actual heartbeat
6421 packet into silcd/packet_send.[ch]. Server now performs
6422 keepalive with all connections.
6424 * Added silc_task_get_first function into lib/silcutil/silctask.c
6425 to return the timeout task with shortest timeout. There was a bug
6426 in task unregistration that caused problems. TODO has been
6427 updated to include that task system must be rewritten.
6429 * The client library will now resolve the client information when
6430 receiving JOIN notify from server for client that we know but
6431 have incomplete information.
6433 * Rewrote parts of silc_server_remove_from_channels and
6434 silc_server_remove_from_one_channel as they did not remove the
6435 channel in some circumstances even though they should've.
6437 * Encryption problem encountered in server:
6439 The LEAVE command used to send the Channel Key packet to the
6440 router immediately after generating it. However, the code
6441 had earlier sent Remove Channel user packet but not immediately,
6442 ie. it was put to queue. The order of packets in the router
6443 was that Channel Key packet was first and Remove Channel User
6444 packet was second, even though they were encrypted in the
6445 reverse order. For this reason, MAC check failed. Now, this
6446 is fixed by not sending the Channel Key packet immediately but
6447 putting it to queue. However, this is more fundamental problem:
6448 packets that are in queue should actually not be encrypted
6449 because packets that are sent immediately gets encrypted
6450 actually with wrong IV (and thus MAC check fails). So, packets
6451 that are in queue should be encrypted when they are sent to
6452 the wire and not when they put to the queue.
6454 However, the problem is that the current system has not been
6455 designed to work that way. Instead, the packet is encrypted
6456 as soon as possible and left to the queue. The queue is then
6457 just purged into wire. There won't be any fixes for this
6458 any time soon. So, the current semantic for packet sending
6461 o If you send packet to remote host and do not force the send
6462 (the packet will be in queue) then all subsequent packets to the
6463 same remote host must also be put to the queue. Only after the
6464 queue has been purged is it safe again to force the packet
6467 o If you send all packets immediately then it safe to send
6468 any of subsequent packets through the queue, however, after
6469 the first packet is put to queue then any subsequent packets
6470 must also be put to the queue.
6472 Follow these rules and everything works fine.
6474 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Added new function silc_server_remove_clients_by_server to
6477 remove all client entries from ID list when the server connection
6478 is lost. In this case it is also important to invalidate all
6479 client entires as they hold the invalid server entry. This
6480 fixes fatal bug when server has lost connection and will reconnect
6483 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Made some sanity checks to silc_server_daemonise like to check
6486 whether the requested user and group actually exists.
6488 * Added sanity check to SKE's silc_ske_responder_finish to check
6489 that the public and private key actually is valid.
6491 * Invalidate the client's nickname when receiving Replace ID
6492 packet and the Client ID is being replaced. This means that the
6493 server will query the nickname if someone needs it (client)
6496 * Sort the ID Cache in client library when the ID Cache data
6497 has changed (needs sorting).
6499 * Do not allow for SILC client to create several connections to
6500 several servers. The client does not support windows right now
6501 and generating multiple connections causes weird behaviour.
6503 Irssi-silc client does support windows and can handle several
6504 connections without problems, see: www.irssi.org and SILC plugin.
6506 * Fixed some places where client was added to the IDList. The
6507 rule of thumb is following (in order to get everything right):
6508 If the client is directly connected local client then the
6509 `connection' argument must be set and `router' argument must be
6510 NULL to silc_idlist_add_client function. If the client is not
6511 directly connected client then the `router' argument must
6512 bet set and the `connection' argument must be NULL to the
6513 silc_idlist_add_client function.
6515 * The funtion silc_server_packet_send_local_channel actually did
6516 not check whether the client was locally connected or not. It
6517 does that now. Fixed a bug related to LEAVE command.
6519 * Fixed Remove Channel User payload parsing bug in server's
6520 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6522 * The server's silc_server_save_channel_key now checks also the
6523 global ID list for the channel as it might not be in the local
6524 list. Fixed a bug related to LEAVE command.
6526 * Is this the end of the [<unknown>] buglet that has been lurking
6527 around for a long time? A little for loop fix in server's
6528 silc_server_command_whois_parse that is used by both IDENTIFY
6529 and WHOIS command. At least, this was a clear bug and a cause
6530 of one type of [<unknown>] buglet.
6532 * WHOIS and IDENTIFY commands call the function
6533 silc_server_command_[whois/identify]_check function even if
6534 we are not router server.
6536 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Added --with-gmp configuration option. If set the GMP
6539 is always compiled in the SILC source tree. If not set then
6540 it is checked whether the system has the GMP3 installed. If
6541 it has then the GMP won't be compiled (the system's headers
6542 and library is used), if it doesn't have it then the GMP is
6543 compiled in the SILC source tree.
6545 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Changed RSA private exponent generation to what PKCS #1
6548 suggests. We try to find the smallest possible d by doing
6549 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6550 not security fix but optimization.
6552 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Added new config entry [Identity] to fork the server and run
6555 it as specific user and group. A patch from Bostik.
6557 * Imported Dotconf configuration library into lib/dotconf.
6558 This will be used to create the SILC configuration files later.
6559 It will appear in the distsribution after this commit.
6561 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6563 * A big code auditing weekend happening. Auditing code for
6564 obvious mistakes, bugs and errors. Also, removing any code
6567 Removed files for being obsolete:
6569 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6570 inline in the file lib/silcutil/silcbuffer.h)
6572 o lib/silcutil/silcbufutil.c (the header has inline versions)
6574 Changed code to fix possible error conditions:
6576 o The buffer formatting routines now check that the destination
6577 buffer really has enough space to add the data. This applies for
6578 both buffer formatting and unformatting
6579 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6580 unformatting was changed to accomodate following rules:
6581 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6582 sent to the function while XXX_*STRING will not allocate or copy
6583 the data into the buffer. Instead it sets the pointer from the
6584 buffer into the pointer sent as argument (XXX_*STRING used to
6585 require that the pointer must be allocated already). This change
6586 makes this whole thing a bit more consistent and more optimized
6587 (note that the data returned in the unformatting with XXX_*STRING
6588 must not be freed now). The routines return now -1 on error.
6590 o Tried to find all code that use buffer_format and buffer_unformat
6591 and added return value checking to prevent formatting and
6592 especially unformatting errors and possible subsequent fatal
6595 o Changed ske->x and ske->KEY to mallocated pointers in
6596 lib/silcske/silcske.h. Fixed possible data and memory leak.
6598 o Added return value checking to all *_parse* functions. Fixed
6599 many memory leaks as well.
6601 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6602 so that buffer overflows would not happen. All code now also
6603 checks the return value as it can fail.
6605 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Added reconnection support to server if the normal server looses
6608 its connection to the router (for example if router is rebooted).
6609 The server performs normal reconnection strategy implemented
6610 to the server. Affected file silcd/server.c.
6612 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Added new packet type SILC_PACKET_SET_MODE that is used to
6615 distribute the information about changed modes (for clients,
6616 channels and clients channel modes) to all routers in the
6617 network. Updated the protocol specification accordingly.
6619 Added functions into silcd/packet_send.c and
6620 silcd/packet_receive.c: silc_server_send_set_mode,
6621 silc_server_set_mode.
6623 Added new files silcmode.[ch] into lib/silccore that implements
6624 the encoding and decoding of Set Mode Payload. Added new type
6625 SilcSetModePayload. Moved the definitions of different modes
6626 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6628 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Oops, a little mistake in server's connection authentication
6631 protocol. The protocol is not ended with FAILURE but with
6632 SUCCESS if the authentication is Ok. :) Affected file is
6635 * Implemented NICK_CHANGE notify handling in server in the file
6636 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6637 the local clients on the channel. After the changing nickname
6638 in router environment snhould work and the [<unknown>] nickname
6639 should appear no more.
6641 The silc_server_replace_id function that receives the Replace ID
6642 payload now sends the NICK_CHANGE notify type also in the file
6643 silcd/packet_receive.c
6645 * Changed WHOIS and IDENTIFY command to support the maximum amount
6646 of arguments defined in protocol specs (3328 arguments). This
6647 fixed a bug that caused problems when there were more than three
6650 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Added extra parameter, command identifier, to the
6653 silc_client_send_command so that explicit command identifier
6656 Changed that ID list routines uses specific command identifier
6657 when sending WHOIS/IDENTIFY requests to the server so that they
6658 can be identified when the reply comes back.
6660 Affected files lib/silcclient/command.[ch],
6661 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6663 * Added `sender' argument to silc_server_packet_send_to_channel
6664 to indicaet the sender who originally sent the packet to us
6665 that we are now re-sending. Ignored if NULL. Affected file
6666 silcd/packet_send.[ch].
6668 * Added some server statistics support in silcd/server_internal.h
6669 SilcServerStatistics structure and around the server code. Also
6670 send some nice statistics information when client is connecting
6673 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Fixed channel ID decoding in server's JOIN command reply in
6676 silcd/command_reply.c
6678 * Fixed braodcasting of replace ID payload to not to send it if
6679 we are standalone server in silcd/packet_receive.c.
6681 * Fixed all channel message sending routines to not to send
6682 packets to clients that has router set, since they are routed
6683 separately in the same function earlier. Affects file
6684 silcd/packet_send.c and all channel packet sending functions.
6686 * In USERS reply, res_argv[i] are not allocated, the table
6687 is allocated. Thus changed that free the table, not its
6690 * In server's whois_check and identify_check if the client is
6691 locally connected do not send any WHOIS commands - they are not
6694 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * Fixed some minor bugs in client when sending WHOIS command. The
6697 arguments was in wrong order.
6699 * Removed statis function add_to_channel from server in
6700 silcd/command.c that was previously used with the joining but
6703 * Tested USERS command in router environment successfully with two
6704 routers, two servers and two clients.
6706 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Reorganized the USERS command and command reply in client library
6709 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6710 When the command is given by user we register a pending command
6711 callback that will reprocess the command after the reply has been
6712 received from the server. When reprocessing the packet we then
6713 display the information. Thus, the USERS information is displayed
6714 now in the command callback instead of in the command reply
6715 callback. The processing of the command is same as previously
6716 when server has sent the command reply in the JOINing process.
6718 * Added to USERS command in silcd/command_reply.c to join the client,
6719 we didn't use to know about, to the channel after we've created
6720 a client entry for it. Also, for clienet we did know already still
6721 check whether it is on the channel or not and add it if not.
6723 * Removed silc_server_command_join_notify as the function and its
6726 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Changed the client's pending command handling to the same as the
6729 server's pending command handling. It is also now possible to
6730 execute command reply functions from other command reply
6731 function as the function callbacks for commands and command
6732 replies are one and same. The pending commands are not static
6733 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6734 in client connection context. Thus, pending commands are server
6735 connection specific as it is convenient.
6737 Changed the function silc_client_command_pending and
6738 silc_client_command_pending_del and added new function
6739 silc_client_command_pending_check. Removed the
6740 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6743 * Added cmd_ident, current command identifier, to the client
6744 connection context in lib/silcclient/client.h to keep track on
6745 command identifiers used in command sending. Client's command reply
6746 function handling now supports the mandatory command identifiers.
6748 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6749 funtions in client to fully support pending command callbacks.
6751 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6752 as one of the arguments to the application in the command reply
6755 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6756 before first releasing SILC but came back. Now it is removed again
6757 and should come back nomore. The FORWARDED flag was used only
6758 by the JOINing procedure by forwarding the command packet to router.
6759 Now, the JOINing procedure has been changed to more generic (due
6760 to various router environment issues) and FORWARDED is not needed
6761 anymore for anything. The protocol specification is yet to be
6764 Now, removed silc_server_packet_forward from server and the flag
6765 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6767 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Renamed NAMES command to USERS command. The NAMES was named that
6770 due to historical reasons. Now it is renamed. Also, rewrote
6771 parts of the USERS command. The nickname list is not sent anymore
6772 by the server. Only Client ID and mode lists are sent in the USERS
6773 command. Changed this also to the protocol specification.
6775 The client now resolves the names and stuff after it receives
6776 the USERS list from the server when joining to the channel.
6778 * WHOIS and IDENTIFY commands has been changed to support multiple
6779 Client ID's per command. One can now search for multiple users
6780 in the network by sending only one WHOIS or IDENTIFY command.
6781 Changed the code and the protocol specifications.
6783 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6784 uses silc_server_command_whois_parse to parse the request. */
6786 * If normal server, do not parse the WHOIS and IDENTIFY requests
6787 before sending it to the router. Saves some time.
6789 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Fixed JOIN command on client library. Wrong number of arguments
6792 used to crash the client.
6794 * Added silc_server_channel_has_global function to check whether
6795 channel has global users or not.
6797 * Added silc_server_channel_has_local function to check whether channel
6798 has locally connected clients on the channel.
6800 * The silc_server_remove_from_one_channel now checks whether the
6801 channel has global users or not after given client was removed from
6802 the channel. It also checks whether the channel has local clients
6803 on the channel anymore. If it does not have then the channel entry
6804 is removed as it is not needed anymore.
6806 * The silc_server_notify now checks on JOIN notify whether the joining
6807 client is one of locally connected or global. If it is global then
6808 the channel has now global users on the channel and that is marked
6809 to the channel entry. Also, it now saves the global client to
6810 global list who is joining and JOINs it to the channel. This is
6811 for normal server, that is.
6813 Changed silc_server_send_notify_on_channel,
6814 silc_server_packet_relay_to_channel and
6815 silc_server_packet_send_to_channel check if we are normal server
6816 and client has router set (ie. global client) do not send the
6817 message to that client, as it is already routed to our router.
6819 * Implemented LEAVE notify type handling in silc_server_notify
6822 * Tested LEAVE command in router environment successfully. Tested
6823 with two routers, two servers and two clients.
6827 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6829 * Implemented SIGNOFF notify type handling in silc_server_notify
6832 * silc_server_remove_id now removes the client entry from all channels
6833 it has joined and thusly sends SIGNOFF notify type.
6835 * Rewrote the NAMES list generation in server by removing two excess
6836 loops. The lists are created now inside one loop.
6838 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * silc_server_remove_channel_user checks now also global list
6841 for channel and client.
6843 * silc_server_new_channel_user checks now both local and global
6844 list for channel and client. Fixed a bug in client id decoding.
6845 Used to decode wrong buffer.
6847 * silc_server_channel_message checks now both local and global
6848 list for channel entry.
6850 * Tested channel joining (hence JOIN) in router environment
6851 successfully. Tested with two routers, two servers and two
6854 * Tested channel message sending in router environment successfully.
6856 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * Added silc_server_save_channel_key into server.[ch] to save the
6859 received channel key in Channel Key payload processing. It is
6860 also used in JOIN command reply handling.
6862 Equivalent function silc_client_save_channel_key added into
6863 client.[ch] into client library.
6865 * Changed JOIN command reply to send information whether the channel
6866 was created or not (is existing already) and the channel key
6867 payload. Changed protocol specs accordingly.
6869 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6870 the request was sent by ID and not by nickname. Crashed on
6873 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6876 now correctly save the received data.
6878 * silc_server_free_sock_user_data now notifies routers in the
6879 network about entities leaving the network.
6881 At the same time implemented functions silc_server_remove_id
6882 and silc_server_send_remove_id to receive and send REMOVE_ID
6883 packets. The packet is used to notify routers in the network
6884 about leaving entities. The ID removed will become invalid in
6887 * Added function silc_idlist_del_server into server. Removes and
6888 free's server entry from ID list.
6890 * silc_server_private_message function now checks, if we are router,
6891 that the destination ID really is valid ID, naturally.
6893 * In router when NEW_ID packet is received (for new client) the
6894 hash of the Client ID is saved in the ID Cache but the
6895 client->nickname is set to NULL, instead of putting the hash
6898 IDENTIFY command now also checks that client->nickname must be
6899 valid. If it is not if will request the data from the server who
6900 owns the client. Added new function
6901 silc_server_command_identify_check.
6903 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6904 to set the command to already allocated Command Payload.
6906 * Tested private message sending in router environment with two
6907 routers, two servers and two clients. Fixed minor bugs and now
6910 * Fixed segfault from client's NAMES command. Used to crash if
6913 * Forwarded packets must not be routed even if it is not destined
6914 to the receiver. Changed server code comply with this.
6916 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Added `require_reverse_mapping' boolean value to ServerParams
6919 structure. If TRUE (not default) the server will require that
6920 the connecting host has fully qualified domain name.
6922 If the reverse mapping is not required and hostname could not be
6923 found the IP address is used as hostname.
6925 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6927 * Implemented version string checking to both client and server.
6928 The check is incomplete currently due to the abnormal version
6929 strings used in development version of SILC.
6931 * Changed all command functions in server to use the new
6934 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Changed char *data to unsigned char *data in ID Cache system to
6937 support binary data as ID Cache data. Changed code to support
6938 binary data in lib/silccore/idcache.c.
6940 * Renamed silc_server_packet_relay_command_reply to
6941 silc_server_command_reply as it is normal packet receiving
6942 function. Rewrote the function to accept command replys for
6943 servers and not only for clients.
6945 * Mark remote router always as registered server if we are connecting
6946 to it. Otherwise, commands sent by the router to us are ignored.
6948 * All ID List find routines now returns the ID Cache Entry pointer
6949 as well if requested.
6951 * WHOIS command works now in router environment, tested with two
6952 routers, two servers and two clients.
6954 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6955 in router environment (as it is almost equivalent to WHOIS) but
6956 hasn't been tested thoroughly. Added new functions:
6958 silc_server_command_identify_parse
6959 silc_server_command_identify_send_reply
6960 silc_server_command_identify_from_client
6961 silc_server_command_identify_from_server
6963 * Disabled route cache adding because adding two different ID's with
6964 same IP replaces the old cache entry thus giving wrong route.
6965 The entry->router->connection is always the fastest route anyway
6966 so route cache may not be needed. Of course, new routes maybe
6967 established after receiving the ID when the entry->router->connection
6968 might not be anymore the most optimal.
6970 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Add route cache for received ID for fast routing.
6974 * Added silc_server_packet_route to route received packet on router
6975 that is not destined to us.
6977 * Renamed silc_server_get_route to silc_server_route_get.
6979 * Added id_string and id_string_len fields into SilcServer to
6980 include encoded ServerID for fast comparing without excess
6981 encoding of the ID's.
6983 * Cleaned up WHOIS command on server side. Added following static
6986 silc_server_command_whois_parse
6987 silc_server_command_whois_check
6988 silc_server_command_whois_send_reply
6989 silc_server_command_whois_from_client
6990 silc_server_command_whois_from_server
6992 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6993 arguments in command replies. All command functions should be
6994 updated to use this macro.
6996 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Minor typo fixes on command reply handling on server.
7000 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7002 * Added silc_server_command_add_to_channel internal routine to add
7003 the client to the channel after router has created the channel and
7004 sent command reply to the server.
7006 * Added generic silc_server_send_command to send any command from
7009 * Use static buffer with ID rendering instead of duplicating data.
7011 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Fixed a channel user mode bug when joining to a channel server gave
7014 everybody channel founder rights, oops.
7016 * We mark ourselves as the router of the incoming server connection
7017 if we are router ourselves. This way we can check in some packet
7018 sending functions whether it is locally connected server. For
7019 incoming router connections we put NULL.
7021 * For router sending packets locally means now always sending the
7022 packet cell wide; to local clients and local servers. For normal
7023 server sending packet locally means sending it to only local
7026 * Fixed the JOIN command to really work in router environment. If the
7027 channel is created it is always created by the router. Router is
7028 also responsible of making the initial joining to the channel,
7029 sending JOIN notify to the sending server and distributing
7030 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7031 does not exist server doesn't do anything else but forward the
7032 command to the router which performs everything.
7034 * Added silc_server_send_channel_key function to send the Channel Key
7037 * Added silc_server_create_channel_key to create new channel key. The
7038 channel key is now re-generated everytime someone joins or leaves
7039 a channel, as protocol dictates. Note: channel->key_len is the
7042 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7045 packet_receive.[ch] to separate packet sending and receiving
7046 routines. The server.[ch] now includes everything else including
7047 actual packet processing (writing and reading data) and other
7050 Renamed silc_server_private_message_send_internal to
7051 silc_server_send_private_message. The routine is still though
7052 used only to relay private messages as server does not send
7053 private messages itself.
7055 Renamed silc_server_new_channel to silc_server_create_new_channel
7056 and added new function sicl_server_new_channel that handles the
7057 incoming New Channel packet. Added also new sending function
7058 silc_server_send_new_channel to send New Channel Payload.
7060 * Added new function silc_server_notify to process incoming notify
7061 packet to the server/router. Server may then relay the notify
7062 to clients if needed.
7064 * Added new function silc_server_new_channel_user to process incoming
7065 New Channel User packet. Router will redistribute the packet and
7066 send JOIN notify to its local clients and locally connected servers
7067 if needed. Normal server will send JOIN notify to its local client
7068 on same channel when received this packet. Added also corresponding
7069 sending function silc_server_send_new_channel_user to sent the
7072 * Added boolean route argument to send_notif_to_channel and
7073 packet_send_to_channel functions to attempt to route the packet
7074 if it is TRUE and send only locally if it is FALSE.
7076 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * silc_server_replace_id now broadcasts the received replace ID
7079 packet if it is not broadcast packet already. The router must
7080 broadcast to inform other routers about changed ID.
7082 * Added backpointer to server's router into SilcServer context in
7083 silcd/server_internal.h.
7085 * Fixed silc_server_packet_broadcast to send correct broadcast
7088 * The channel key is now distributed to the local client as soon
7089 as it is received from the router (in router environment) so that
7090 no other packet may be sent for the channel until client has
7093 * silc_server_remove_channel_user now broadcasts the received
7094 Remove Channel User packet if it is not broadcast packet already.
7095 The router must broadcast to inform other routers about removed
7098 * Added users field into SilcPacketContext that is a reference count
7099 of the context. One can increase the reference count by calling
7100 silc_packet_context_dup which is now changed to just increase the
7101 reference count instead of duplicating the data. The reference
7102 count is decresed by calling silc_packet_context_free that will
7103 free the data after the reference count hits zero.
7105 For now on the packet context and everything allocated into it
7106 (including the raw packet from network) must be freed by calling
7107 the new silc_packet_context_free function. Added also new function
7108 silc_packet_context_alloc that must be used now to allocate the
7109 context. This also means that if a routine is asynchronous from
7110 silc_[client/server]_packet_parse_type the packet context must
7111 be duplicated by calling silc_packet_context_dup. Otherwise it
7112 gets free'd after silc_[client/server]_packet_parse_type returns.
7113 Also, one must remember that if packet is duplicated then its
7114 reference count must be decresed by calling the free function as
7115 many times as it was duplicated.
7117 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7118 from both client and server.
7120 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Made joining to a channel working in router environment.
7124 * Cleaned up JOIN command on server side and create function
7125 silc_server_command_join_channel internal routine to make the
7128 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7130 * Changed silc_command_pending list to SilcDList. Also, added
7131 `ident' field to SilcServerCommandPending structure to identify
7132 the reply and to call correct callback.
7134 Added silc_server_command_pending_check function to replace the
7135 corresnponding macro. The silc_command_pending list is not
7138 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7139 to set identifier to previously allocated Command Payload. It
7140 is used to set identifier for command when resending Command
7143 * Added silc_command_payload_encode_payload to encode Command
7144 Payload buffer from SilcCommandPayload structure.
7146 * Added silc_argument_payload_encode_payload to encode Argument
7147 payload buffer from SilcArgumentPayload structure.
7149 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7151 * Changed WHOIS command to support router connection on server side.
7152 The whois request is always sent to router unless the server is
7153 standalone server. After server has received the reply from the
7154 router will it send the reply to the client.
7156 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7157 broadcast received broadcast packet. The function is used only
7158 by router. The broadcast packet is always sent to the router's
7161 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7162 render given ID to printable string, for log files for example.
7164 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Made basic router to router connections working. At least they
7167 can now connect to each other but nothing really works the way
7168 they are supposed - yet.
7170 * Added new initiator token to RouterConnection configuration
7171 file in silcd/serverconfig.[ch]. It is used to tell whether we
7172 are the initiator to the remote router or whether we'll expect
7173 the other end to connect.
7175 * Moved registering of listener task to silc_server_init, hence
7176 the server starts listenning as soon as it is run, even if it
7177 does not have connections to other routers. Let's see how well
7180 * Changed default connection retry timeouts for more suitable in
7183 * Removed cipher and such arguments from silc_idlist_add_client
7184 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7185 Added new function silc_idlist_add_data to add the keys and stuff
7188 * Added SilcIDListData structure and added it to SilcClientEntry
7189 and SilcServerEntry as their first field in the structure. This
7190 way we can explicitly cast the ID entries to the SilcIDListData
7191 structure and get common data for the entries. In past, we had
7192 to first check what type of connection it is and then cast it to
7193 correct ID entry type. Now, we can directly cast the opaque
7194 pointer to the SilcIDListData (no matter what ID entry it actually
7195 is) and get the data needed.
7197 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7200 in some circumstances even if threre were timeout tasks, though not
7201 IO tasks, but tasks anyway. Now fixed.
7203 * Defined SilcServerConnection structure to hold connection specific
7204 stuff about directly connected servers and routers. The definition
7205 is currently in silcd/server_internal.h. I thought about having
7206 a bit more important role fro this struct but for now it is used
7207 only when connecting to other server (or router actually).
7209 * Added connecting retry support in server when connecting to
7210 router(s). The retry feature implement exponential backoff
7211 algorithm. Also, added SilcServerParams structure to hold default
7212 parameters for server. For now, it include these retry settings
7213 and are hard coded. After server is moded to be as Silc Server
7214 Library this structure will be more important.
7216 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Changed client librarys channel->clients table to SilcList and
7219 changed code accordingly.
7221 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Changed client's channel table to SilcList and changed code
7224 accordingly. Also changed SilcChannelClientEntry to include back-
7225 pointer to the channel so that client entry can use that structure
7226 as list as well and we have fast cross-reference to the channel.
7227 This change dramatically decreased the complexity of channel
7228 handling with client entry and vice versa (removed one extra
7229 loop when searching for channel entry from many functions).
7231 * Changed server->sim from table to SilcDList and changed code
7234 * NAMES command can now be used from user interface. It will show
7235 the user list on the channel, neatly.
7237 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7238 Code now saves realname of the user if it becomes available.
7240 * Renamed configure.in to configure.in.pre and made ./prepare
7241 script to automatically add correct version string to
7242 configure.in which it creates from configure.in.pre.
7244 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * NAMES command reply now shows users mode with the nickname when
7249 * Moved silc_client_ch[u]mode[_char] functions from
7250 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7251 place sucks, they are utility functions and should be in some
7254 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7256 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7259 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Added TRQ (efficient deque and list library) into lib/trq. This is
7264 a very good list library that is currently used in the SILC. Defined
7265 SilcList API over the library because I didn't like the API very
7266 much. See lib/trq/silclist.h for the API and examples of how to
7267 use the API. Fixed various places in the code to use the new
7268 SilcList API. The SilcList is meant for lists that has a structure
7269 already defined as a list. It is not suitable to add just some
7270 context to the list (in TRQ, the context is the list actually).
7272 So, I defined SilcDList that can be used for the purpose where
7273 predefined list structure does not exit. This can be used as
7274 such list. Now some context just can be added to the SilcDList.
7275 Currently this list is not used in the SILC just yet, though there
7276 are a lot places where this can replace dynamically allocated
7277 tables and I will fix these places, later, to use SilcDList.
7278 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7279 and use TRQ internally).
7281 Also fixed some annoying warning messages that the original TRQ
7282 code generated. Also minor changes to TRQ's Makefile.in.
7284 * Added support for querying by Client ID to both WHOIS and
7285 IDENTIFY commands into server, as required by the protocol.
7287 * Removed method function pointers from SilcBuffer structure. They
7288 weren't used to anything and just increased the context size for
7289 no good reason. This change also made silc_buffer_alloc and
7290 silc_buffer_free functions inline functions.
7292 * Disabled command flooding detection support until it's fixed so
7293 that it accepts commands in but does not execute them more than once
7296 * Added silc_net_localhost(), to return local hostname, into
7297 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7298 that must be initialized before calling silc_client_init.
7300 * Added new function: silc_server_send_notify_on_channels to send
7301 notify messages to all channels client has joined. It is assured
7302 that the message is sent only once per client.
7304 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7305 lib/silcutil/silcutil.[ch] as silc_format function. The new
7306 function is generic and is used by server as well, not only by
7307 the logging routines.
7309 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7310 the provided version string was not acceptable. Added new function:
7311 silc_ske_check_version into lib/silcske/silcske.h. The function
7312 must be implemented by the application (client or server) and it
7313 does not reside in the SKE library. The function checks the version
7314 string remote end sent.
7316 * Added back pointers (to opaque context and to SilcSocketConnection)
7317 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7319 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7320 duplicate packet context structure.
7322 * Changed `notify' client operation to send same arguments as client
7323 receives from server except for ID's. ID's are mapped to correct
7324 ID entry and that is returned. Also, if channel entry is not sent
7325 by server but the notify is for channel the channel entry is sent
7326 to application (otherwise application doesn't know that it is for
7327 channel (library gets it from packet's Destination ID)).
7329 * Added silc_client_remove_from_channels into client library to
7330 remove a client from all channels it has joined to. Used when
7331 received SIGNOFF notify from server. Added also new function
7332 silc_client_replace_from_channels to replace old ID entry with
7333 new ID entry on all channels. Used when received NICK_CHANGE
7336 * Fixed ID Cache list handling in silc_idlist_get_client in
7337 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7338 to get (or query) client by ID.
7340 * Updated TODO list.
7342 * Added connection authentication status message defined by the
7343 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7344 support for these into the code in client and server side.
7346 * Added generic function silc_client_send_command to send any command
7347 with variable argument list. Application should use this function
7348 to send commands if the command functions provided by the library
7349 does not suite for the application's user interface needs.
7351 * Added new `failure' client operation. Application is notified about
7352 received failure packet if client is executing a protocol. In this
7353 case the protocol's execution has failed.
7355 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7356 is required by the protocol.
7358 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7359 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7362 * Added status flag to SilcSKE object to indicate realtime status
7363 of the SKE protocol.
7365 * Application receives now exactly same command reply arguments as
7366 the library receives from server. However, if ID is received the
7367 corresponding ID entry is returned to the application (eg. Client
7368 ID is mapped to correct SilcClientEntry entry and that is returned).
7369 Changed command_reply client operation due to this change.
7371 * Changed all ID's in commands and in command replys as ID Payloads.
7372 Change affected both client and server side codes.
7374 All ID's sent in SILC network (with execption of ID's in SILC
7375 Packet header) are sent in ID Payload to support variable length
7378 * Server now notifies nick changes and notifies all clients on
7379 the channels about the new nickname (about the new Client ID,
7382 * Implemented CMODE command to change channel modes. Supports all
7383 channel modes defined by the protocol specs except ban and invite
7384 lists. (Also, private channel key mode is supported but support for
7385 setting private channel key in client is missing, thus, this mode
7386 has no effect on client side (except that server requires that the
7387 client uses private channel key and normal channel traffic does not
7390 Also, invite mode works per se, but INVITE command does not work
7391 yet correctly, so you can set channel as invite only channel but
7392 inviting clients to the channel does not work (it is yet to be
7393 thought what's the best way to do it).
7395 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7396 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7397 Implemented CUMODE command to change user's mode on the channel.
7398 Supports all modes defined by the protocol specs.
7400 * Added NAMES command reply to return users modes on the channel.
7402 * Removed unnecessary and slow ciphers from lib/silccrypt.
7404 * Set SO_KEEPALIVE option to connection sockets by default.
7406 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7408 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7409 redefined the Notify Payload into protocol specs.
7411 * Added silc_id_payload_parse_id to get ID directly from raw
7414 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7416 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7417 accept searching by Client ID as well.
7419 * Added support for LEAVE and SIGNOFF notify types in client library.
7421 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7422 to parse ID Payload from raw data.
7424 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7426 * Added flags parameter into silc_ske_assemble_security_properties
7427 function in lib/silcske/silcske.[ch].
7429 * Changed notify client operation to fit better for notify messages
7430 sent by server. The notify payload received from server is now
7431 passed to the application (after parsing it to SilcNotifyPayload).
7432 It is application's responsibility to retrieve the arguments
7433 from the payload and show the message the way it wants. The message
7434 sent by server is implementation specific.
7436 * Changed public keys to comply with the protocol specification.
7437 Old public keys are not supported anymore and are not compatible.
7439 * Removed nickname from Channel Payload as the latest draft removed
7440 it. The client must resolve the nickname from the NAMES command
7441 reply received when it joined the channel.
7443 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7445 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Fixed some errors in protocol specification drafts.
7449 * Created lib/silccore/silcnotify.c to implement Notify Payload
7450 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7451 generic payloads described by protocol specifications. The file
7452 includes implementations for ID Payload and Argument Payload.
7454 * Changed Command Payload implementation to use the new Argument
7455 Payload. Changed command_xxxx_payload to command_payload_xxxx
7456 to comply with SILC coding conventions.
7458 * Added suppport for Argument Payload handling in Notify Payload
7459 implementation as protocol requires it. Added the new support
7460 into server and client lib as well.
7462 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * Added support for multiple nicknames on same channel. [n] is
7465 added locally to the nickname if there are more than one same
7466 nicknames on the channel.
7468 * Server now sends all nicknames that matched WHOIS request.
7469 Client also shows the list received from server.
7471 * Added TOPIC command to client side. User can now set and show
7472 current topic on channel.
7474 * Added MOTD command to client and server. Also, server sends the
7475 motd when client connects to the server.
7477 * Changed version strings to comply ISO 8601.
7479 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Fixed protocol error handling in client library. It should now
7482 cope even if the SKE fails for some reason.
7484 * Made new protocol specification drafts for submitting to IETF.
7486 * Implemented TOPIC command to server in silcd/command.c.
7488 * Added two new notify types into lib/silccore/silcnotify.h:
7489 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7490 notify nickname change and topic setting/change on a channel.
7492 * API change of command_reply operation in client library. The
7493 application gets now the status type received from server as well.
7495 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7499 * Cras fixed and optimized the packet handling even further and
7500 it should work now. Minor change to the prototype of function
7501 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7503 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7505 * Added new function into lib/silcutil/silcschedule.[ch]:
7506 silc_schedule_with_fd to select() a specified fd. The function
7507 returns after timeout expires or data arrives or goes. The
7508 function is used by packet routines to wait that all data is
7509 received from network.
7511 * Fixed data reading from network in lib/silccore/silcpacket.c.
7512 The code now assures that all data is read from the fd and then
7513 continues packet processing. This was a bug fix since the code
7514 used to drop some data in some circumstances.
7516 * Added new function into lib/silcclient/client.[ch]:
7517 silc_client_start_key_exchange to start key exchange after
7518 connection has been established to server. The code internally
7519 now uses this funtion but its main purpose was to provide it
7520 for applications that perform their own connecting. After
7521 application has created a connection it merely calls this
7522 function to start the key exchange between client and server.
7523 The library takes care of everything else after that.
7525 Updated also lib/silcclient/README to explain the usage of
7528 * Do not send to application information that connection has
7529 been established. Application gets notified it by connect
7532 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Applied cras's patch to add silc_schedule_one function. The
7535 function runs scheduler once and returns.
7537 * Fixed the scheduler after cras messed it up. The timeout
7538 handling works now as it's supposed to work.
7540 * Added into lib/silccore/ silcnotify.h to include notify
7541 message types support. Changed silc_server_send_notify*
7542 functions, in server.[ch], to support those new notify types.
7543 Added the support for the notify types into client library,
7544 as well. Added new notify client operation into ops.h in
7547 * Changed silc_server_packet_send_to_channel to send normal
7548 packets instead of just channel message packets. The function
7549 is now used to send the notify packets to channels. It is not
7550 used to send channel message packets anymore, as server never
7553 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7554 va_arg()s as it seems to require it nowadays. I guess, if SILC
7555 is compiled with older va_arg() the new code should work anyway.
7557 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Splitted core library. Core library (lib/silccore) includes
7560 now only SILC protocol specific core (and common) components.
7561 Created new utility library (lib/silcutil) that includes more
7562 generic purpose stuff. The stuff for util library was taken
7563 from the old core library. This was minor and easy split.
7565 * Created SILC Client Library (lib/silcclient) that includes
7566 implementation of the SILC client without user interface. This
7567 was major move from silc/ directory. The code has been changed
7568 so that it is transparent towards the user interface. The
7569 silc/ directory includes now the same user interface as before
7570 and it uses the new client library. Read lib/silcclient/README.
7571 Basicly, the client library performs everything else related
7572 to SILC except user interface handling. Also, configuration
7573 files are considered to be part of user interface and library
7574 does not handle them.
7576 This change also changed a lot of structures, function naming etc.
7577 Most important change was that SilcClientWindow object was
7578 renamed to SilcClientConnection in the client library. Created
7579 also new file lib/silcclient/ops.h. Also added new files
7580 silc/local_command.[ch] and silc/client_ops.[ch].
7582 All these changes were made to make it easier for user interface
7583 designers to create what ever user interface for the SILC client
7586 It is also expected that the server will be moved to lib
7587 directory as well and SILC Server Library will be created;
7588 sometimes in the future.
7590 * Removed Local commands from lib/silccore/silccommand.h as
7591 they are application specific and new client library does not
7592 handle any of those anymore.
7594 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7595 old client implementation in silc/.
7597 * Added support for callback functions in SILC_LOG_* macros.
7598 Application can now set its own callbacks that will be called
7599 instead of using the default functions that will always print
7600 the debug messages to stderr (or stdout). Also, debugging can
7601 now be disabled by setting silc_debug to FALSE and re-enabled by
7602 setting it to TRUE. Note, that logging will still work even
7603 if debugging is disabled.
7605 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7606 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7607 silc_log_reset_debug_callbacks.
7609 * To enable debugging in silc client one must give now -d
7610 option on command line.
7612 * Changed silc_schedule_init to automatically allocate task queues
7613 if they are not allocated before calling it.
7615 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Added GMP 3.1 into math library.
7619 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7621 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7622 a channel in SILC network. The packet is used by servers and
7623 routers to notify other routers that user has left a channel.
7624 This little feature was missing until now. Added the feature
7625 to protocol specification as well.
7627 Added functions: silc_server_send_remove_channel_user and
7628 silc_server_remove_channel_user into server.[ch].
7630 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7631 lib/silccore/silcpacket.h. However, they are not implemented
7634 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Fixed joining to a channel and sending channel messages
7637 between server and router. The channel message sending should
7638 now work inside a cell.
7640 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Fixed the private message sending between server and router.
7643 The private message sending should now work inside a cell.
7645 * Added silc_server_replace_id into server.[ch] to replace
7646 existing ID in the SILC network.
7648 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7649 and silc_idlist_replace_server_id into idlist.[ch] in server.
7651 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Fixed the server to server connections. Server can again now
7654 connect to router. Router to router connections probably does
7657 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7659 * Added dynamic protocol registering support. Now protocols can
7660 registered and unregistered on the fly. Patch by cras.
7662 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7664 * Added lib/contrib directory to hold routines that some platforms
7665 don't have but are needed by SILC.
7667 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7668 into lin/contrib to provide getopt() and getopt_long() for
7669 those who don't have it.
7671 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Added AWAY command to client. When away message is set and
7674 client receives a private message packet the client automatically
7675 replies to the sender with the away message.
7677 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7678 bug seemed to be the cause of recent problems when compiling
7681 * Added version detection support to SKE protocol specification
7682 and added the new changes to the SKE implementation as well.
7683 There were other minor changes in the SKE protocol as well.
7685 Many changes in lib/silcske/silcske.[ch] and in
7686 lib/silcske/payload.[ch].
7688 * Added ^U functionality, clear input line. Patch from cras.
7690 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7692 * Mainly small bugfixes on core library. Fixed some debugging
7693 logging and buffer overflow in silclog.c.
7695 * Updated config.sub and config.guess on the distribution tree.
7697 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7699 * Added command lagging support in server. Client may execute
7700 commands now only once in two seconds.
7702 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7704 * Optimized packet reception. MAC computation and checking is now
7705 also more optimized. A lot previously duplicated code is now
7706 used as generic by both client and server.
7708 * Fixed key pair generation in clientutil.c
7710 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7712 * Added into lib/silccore/silcbufutil.[ch] new function;
7713 silc_buffer_realloc.
7715 * Moved generic packet sending/encryption functions to
7716 lib/silccore/silcpacket.[ch] from client and server. Some
7717 rewriting of the functions.
7719 * Moved all generic packet reception/decryption functions to
7720 lib/silccore/silcpacket.[ch] from client and server. The
7721 packet processing is now much cleaner in both client and server.
7722 These were major changes in both client and server.
7724 * Created many common functions in server to do packet sending.
7725 Previously code were duplicated a lot, this has been removed
7728 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Rewrote major parts of the ID cache system. Don't know
7731 whether it is better now or not but at least the API is more
7734 * Major rewrite on ID cache stuff on client because of the ID
7735 cache API changes. Added idlist.c to client.
7737 * Also major rewrite on ID cache stuff on server as well.
7738 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7739 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7740 in hand, instead they are all put into the ID cache system now.
7741 All server_idlist_* routines uses ID cache now instead of
7742 traversing its own lists (those lists does not exist anymore).
7743 SilcIDList though still exists. Also, SilcXXXEntry's are
7746 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7748 * Finally made the SKE implementation compliant to the protocol
7749 specification. All mp integers are now binary encoded as
7750 opposed being HEX encoded.
7752 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7755 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7756 functions: silc_[encode/decode]_pem. Also added function
7757 silc_encode_pem_file to PEM encode with newlines ('\n') for
7760 * SILC public keys are now encoded either PEM or binary. Same
7761 option is for private keys as well. By default private keys
7762 are binary encoded and public keys PEM encoded. Silly HEX
7763 encoding were removed.
7765 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7766 function to create fingerprints.
7768 * Fixed a bug in SHA1; does not change the original data anymore.
7770 * Partly implemented INFO command on client and server side.
7771 Fixed CLEAR command. Changes to SERVER command; show current
7772 server(s) when giving command without arguments. Added
7773 VERSION command to client.
7775 * Added check to server that unregistered connections cannot
7776 execute commands (unless it is specificly allowed).
7778 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7780 * Fixed screen refresh.
7782 * Fixed channel joining bug from client. On some circumstances
7783 client tried to join to a channel it had already joined.
7785 * Added public key verification process into client's protocol.c.
7786 The client now verifies the public key from user and saves
7787 it into ~./silc/serverkeys/ directory.
7789 Added into: clientutil.[ch]: silc_client_verify_server_key.
7791 * Changed SKE protocol's silc_ske_initiator_finish function
7792 to accept callback function that verifies the received public
7793 key. Removed old silc_ske_verify_public_key function.
7795 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7797 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7798 silc_pkcs_private_key[_data]_set.
7800 * Made the password and public authentication more cleaner in
7801 server's protocol.c.
7803 * Removed historic and obsolete protocol `channel_auth' from
7804 both client and server.
7806 * Removed wrong way of sending command status messages from
7807 server to client in server's command.c. The old way violated
7808 protocol specification.
7810 Changes to silccore/silccommand.[ch]: removed
7811 silc_command_encode_status_payload -> not needed anymore,
7812 changed silc_command_encode_payload_va to accept extra
7813 argument on variable argument list. The argument type must
7814 now be provided to the function. Also, added new function:
7815 silc_command_encode_reply_payload_va which is same as
7816 normal command_encode_payload_va except command status type
7817 is provided as extra argument.
7819 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7821 * Added ~./silc directory handling. The directory includes the
7822 public and private keys for the client.
7824 Added silc_client_check_silc_dir, silc_client_create_identifier
7825 and silc_client_load_keys.
7827 * Implemented SILC protocol compliant public key. Added public
7828 and private key saving to and loading from files.
7830 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7831 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7832 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7833 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7834 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7836 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7837 silc_pkcs_load_[public/private]_key.
7839 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7841 * Added silc_server_get_route (route.[ch]) to get connection
7842 data for the fastest route for given ID.
7844 * Implemented INVITE command on client and server. The command
7845 were re-defined in the SILC Protocol Specification and the
7846 implementation now complies with the specification.
7848 * Implemented PING command on client and server.
7850 * Implemented NAMES command on client and server. The server side
7851 supports currently only normal server not router server yet.
7852 Some changes to NAMES definition in SILC protocol specification.
7854 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Implemented LEAVE command on client and server.
7858 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7859 again. This change was made to the protocol as well. Server
7860 should not violate the protocol specification anymore.
7862 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7864 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7865 was tested. SOCKS4 was not but should work anyway.
