1 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added SILC_PROTOCOLVERSION macro to check protocol version
4 of a socket connection. The affected file is
5 lib/silcutil/silcsockconn.h.
7 * Added better error logging in rekey protocol. Affected file
10 * Do not check public key types in SKE during rekey. Affected
11 file lib/silcske/payload.c.
13 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Some client implementations quit network by doing first LEAVE
16 and then immediately SIGNOFF (like Bombyx). We now do check
17 after a short time after LEAVE notify and check whether the
18 client is still valid after LEAVE, and if not we remove it from
19 cache. Affected file is lib/silcclient/client_notify.c.
21 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
23 * Merged version 1.1.4 of zlib. Even if it not currently in use,
24 it's good not to have security holes here.
26 * Fixed a negative refcount situtuation for the config context.
27 Affected file is silcd/serverconfig.c.
29 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
31 * ROBOdoc documented lib/silcutil/silcutil.h.
33 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
35 * Optimized even more the SilcPacketContext structure. Now
36 totally saved 16 bytes of memory per context after optimization.
37 Affected files are lib/silccore/silcpacket.[ch].
39 * Made strict checks for valid SILC IDs. Affected file is
40 lib/silccore/silcid.c.
42 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
44 * Changed the object argument for silc_cipher_register,
45 silc_hash_register, silc_hmac_register and silc_pkcs_register
46 to const. Affected files are lib/silccrypt/silccipher.[ch],
47 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
49 * Changed the silc_get_username and silc_get_real_name to
50 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
52 * Fixed the Irssi SILC Client to use the silc_get_username and
53 silc_get_real_name insted of glib routines since the glib
54 routines only corrupt stack. Fixes the Irssi SILC to work in
55 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
57 * Fixed the Irssi to not use g_get_home_dir since it crashes
58 or returns garbage on cygwin and corrupts stack. Added function
59 get_home_dir to Irssi routines. Affected files are
60 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
62 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
64 * Made some structure optimizations. SFTP memory FS MemFSEntry
65 entry structure. Optimized SilcTask structure. Optimized
66 SilcPacketContext structure.
68 Affected files lib/silcsftp/sftp_fs_memory.c,
69 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
71 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
73 * And yet again reverted back the config thing since Johnny
74 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
77 * Fixed memory leaks from config object. Affected files are
78 silcd/serverconfig.[ch].
80 * Added support for adding new connections to the server in rehash.
81 After rehash they take effect.
83 Added support for changing the maximum allowed connections in
84 rehash. The number can grow but going smaller is not supported.
86 Added function silc_server_num_sockets_by_remote to the
87 silcd/server_util.[ch].
89 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
91 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
93 * Added preliminary checking during config parsing for a valid
94 public/private key and removed further checks in the code.
95 Affected files are silcd/serverconfig.[ch], server.c.
97 * Moved functions silc_server_drop() and silc_server_daemonise()
98 from server.c to silcd.c since they are stricly related to
99 the application activity.
101 * Reverted a small part of the automatic ref/unref since
102 it caused a double unref in some situations. Affected
103 files are silcd/silcd.[ch], server.c, serverconfig.c.
105 * Added some .cvsignore files in the lib directory.
107 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
109 * Fixed silc_net_gethostbyaddr to correctly resolve by
110 address. Affected file lib/silcutil/silcnet.c.
112 * Fixed the notify relaying to client. The HMAC to be used
113 with relayed packets ws wrong and caused decryption failure
114 at the client end. Affected file is silcd/packet_receive.c.
116 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
118 * Created new branch silc_protocol_1_0_branch.
120 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
122 * Changed the silc_server_config_* routines to be SilcServer
123 independent. They are now officially application specific code
124 and not part of generic server implementation. Affected files
125 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
127 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
129 * Added automatic referencing of config context in the
130 silc_server_config_alloc, and automatic unreferencing in the
131 silc_server_config_destroy. Affected files are
132 silcd/serverconfig.[ch], silcd/silcd.c.
134 * Fixed the silc_log_quick handling in the logging routines.
135 It didn't log quickly when it was TRUE. Affected file is
136 lib/silcutil/silclog.c. Also the flush delay was set even
137 if it was 0 in config file. Affected file is
138 silcd/serverconfig.c.
140 * Added support for changing key pair of the server in rehash.
141 Affected file silcd/server.c.
143 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
145 * Fixed the TOPIC_SET notify to not cras. It changed the topic
146 too early, before getting the channel entry. Affected file
147 is silcd/packet_receive.c.
149 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
151 * Added functions silc_server_config_[ref/unref], these are used
152 to prevent that the config object is destroyed.
154 No longer directly affect global variables silc_log_quick and
155 silc_log_delay, they are first cached inside the config object
156 and then applied with silc_server_config_setlogfiles().
158 silc_server_config_set_defaults() is now internal to
159 serverconfig.c, there are no reasons to show this internal stuff
162 Affected files are silcd/serverconfig.[ch].
164 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
165 fprintf's to stderr, since some code may be executed again after
166 the server went into the background. Affected files are
169 * Added rehash support. Added function silc_server_rehash() that
170 will perform all the basic tasks of the rehashing procedure.
172 * Added command line option `-x, --hexdump'. This will enable the
173 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
174 The option `--hexdump' implies `--debug'.
176 * Fixed a bad bug in the logging APIs (silcutil library) where
177 the application would crash after calling silc_log_reset_all().
179 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
181 * Fixed the KICKED notify handling in client library to
182 correctly remove the channel and all entries from the
183 channel when I was kicked. This bug crashed the client.
185 Fixed yet another but in KICKED notify handling to remove
186 the kicked client correctly from the channel.
188 Affected file is lib/silcclient/client_notify.c.
190 * Fixed a minor bug in looking up correct client entry
191 in KICKED notify in server. Affected file is
192 silcd/packet_receive.c.
194 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
195 sources correctly to distribution. Fixes --with-gmp option.
197 * Removed the manual rehashing from ID Cache, and changed it
198 to use the SILC Hash Table's auto rehash feature. Affected
199 file is lib/silccore/silcidcache.c.
201 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Fixed a bug in the silc_client_nickname_format function that
204 handles the multiple same nickname formatting. Two clients
205 with same nickname caused problems after the first one left
206 and rejoined. It didn't format the nickname correctly.
207 Affected file is lib/silcclient/idlist.c.
209 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
211 * Don't change the topic if olod topic is same as new one.
212 Affected file is silcd/packet_receive.c.
214 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
216 * Added cross-reference support to the SILC Documentation
217 generator. All types across all HTML files are now cross-
218 referenced. Affected files util/robodoc/generator.c and
219 scripts/silcdoc/silcdoc.
221 * Added file lib/silcutil/silctypes.h to include all the
222 arithmetic type definitions and some macros. Removed
223 includes/bitmove.h and moved macros to silctypes.h.
225 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
227 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
229 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
231 * Added `type' argument to silc_id_payload_parse_id function which
232 now returns the type of the ID to the sent pointer. Affected
233 file is lib/silccore/silcid.[ch].
235 * Added check for CMODE_CHANGE notify type that mode change is
236 allowed by the sender. Affected file silcd/packet_receive.c.
238 * Added check for CUMODE_CHANGE notify type that mode change is
239 allowed by the sender. Affected file silcd/packet_receive.c.
240 Added the ID type as CUMODE_CHANGE notify type as argument
241 to the `notify' client operation. Affected files are
242 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
244 * Added function silc_client_add_server to the client library.
245 Added support for resolving also channel and server info when
246 received unknown entity in notify packet. Affected files are
247 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
249 * Added function silc_command_get_status to return the command
250 status from the command reply's argument payload. Affected files
251 are lib/silccore/silccommand.[ch].
253 * Added check for KICKED notify type that the kicking is
254 allowed by the client. Affected file silcd/packet_receive.c.
256 * Created function silc_get_input which can be used to get input
257 (echo on or off) from user on command line. Affected files are
258 lib/silcutil/silcutil.[ch].
260 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Optimized silc_server_packet_relay_to_channel function.
263 Added new function silc_channel_message_payload_encrypt which
264 can be called directly if channel message payload needs to
265 be encrypted and is already encoded (no need to call _encode
266 function). Packet relaying is now done by router without any
267 extra memory allocations. Affected files are
268 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
271 * Fixed the INVITE notify handling. It took wrong arguments
272 as invite list and invite delete. Affected file is
273 silcd/packet_receive.c.
275 * Added check for TOPIC_SET notify type that the topic change is
276 allowed by the client. Affected file silcd/packet_receive.c.
278 * Added check for INVITE notify type that inviting is allowed by
279 the client. Affected file silcd/packet_receive.c.
281 * Changed the silc_server_client_on_channel to return the
282 SilcChannelClientEntry as well. Moved the function
283 silc_server_check_cmode_rights to server_util.[ch].
284 Affected files are silcd/server_util.[ch], silcd/command.c.
286 * Added function silc_server_check_umode_rights to check whether
287 changing client's user mode is allowed. Added check for
288 UMODE_CHANGE notify type that the umode change is allowed
289 by the client. Affected files are silcd/server_util.[ch],
290 silcd/packet_receive.c and silcd/command.c.
292 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
294 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
295 ID length. It ignored that ID can be IPv6 based as well.
296 Affected file lib/silccore/silcpacket.h.
298 * Fixed the silc_id_id2str and silc_id_str2id to take the
299 IPv6 address offset's into consideration. Affecte file is
300 lib/silccore/silcid.c.
302 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
304 * Fixed the internal Unix scheduler functions to check for
305 NULL context they may receive. The affected file is
306 lib/silcutil/unix/silcunixschedule.c.
308 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
310 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
311 can specify different directory with --home command line
312 parameter. Affected files irssi/src/silc/core/client_ops.c,
315 * SILC-specific commands aren't now executed if the active server
316 isn't of SILC-type, so there won't be problems with having
317 IRC and SILC protocol support in same client. Affected files
318 irssi/src/silc/core/silc-channels.c, silc-servers.c,
321 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
323 * Improved the signal support in SILC Schedule. Added new
324 function silc_schedule_signal_call which is used by application
325 to mark a signal to be called. It is now safe to perform
326 any kind of tasks in signal callbacks since it is guaranteed
327 that the application specified signal callback is called
328 after the signal is over. Affected files are
329 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
331 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
333 * Added `name' field to SilcChannelPrivateKey to represent
334 application given name for the key. Moved also the context from
335 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
336 Added the `name' argument also to the function
337 silc_client_add_channel_private_key.
339 Added function silc_client_current_channel_private_key to set the
340 current channel private key in use.
342 Added "change" command to KEY command which can be used to change
343 the current channel private key. Bound the command also to
346 Also affected files lib/silcclient/client_channel.c,
347 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
349 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
351 * Added silc_rng_get_byte_fast function in to the
352 lib/silccrypt/silcrng.[ch].
354 * Changed the interface of silc_packet_assemble and the
355 silc_packet_send_prepare. If silc_packet_assmble is now
356 called the application does not call silc_packet_send_prepare
357 because the library will call it automatically. These
358 interfaces now also return a reference to the outgoing buffer
359 which includes the assembled packet, which the application can
360 use to encrypt the packet.
362 Affected files are lib/silccore/silcpacket.[ch],
363 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
364 silcd/packet_send.c, server_backup.c and packet_receive.c.
366 * Fixed a packet sending bug on very high load, where outgoing
367 packet queue wasn't handled correctly and packets got corrupted.
368 Affected files are lib/silcutil/*/silc*sockconn.c,
369 lib/silcclient/client.c and silcd/server.c.
371 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
373 * Added macro SILC_PACKET_DATALEN which can be used during
374 packet assembling to check whether the data to be added to
375 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
376 len is truncated until it fits it.
378 Added checks for maximum length of channel message payload and
379 private message payload also.
381 Added checks for maximum packet length in server and in
384 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
385 lib/silcclient/client.c, lib/silccore/silcchannel.c and
386 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
387 lib/silcclient/client_prvmsg.c.
389 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
391 * Added silc_server_packet_queue_purge call to the
392 silc_server_disconnect_remote to assure that all data in the
393 queue before disconnecting is sent to the network. Affected
396 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
398 * Added the deleting of server's own ID cache entry to the
399 silc_server_free function. Free also everything else that
400 has been allocated in silc_server_init. The affected file
403 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
405 * Added functions silc_parse_version_string, silc_version_to_num,
406 and silc_ske_parse_version to parse SILC protocol style version
407 strings. Affected files lib/silcutil/silcutil.[ch] and
408 lib/silcske/silcske.[ch].
410 * Added new configuration params: version_protocol, version_software
411 and version_software_vendor to specify what version the remote
412 host must at least be to be able to connect to server. The vendor
413 string can be regex matched too. Added new function
414 silc_server_connection_allowed to check maximum number of allowed
415 connections, and allowed versions for incoming connections.
416 Affected files are silcd/server.c, server_util.[ch] and
419 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Added preliminary support for signals in scheduler. The
422 signals we care about are now blocked always when the scheduler
423 is locked. This way we can synchronise the use of signal with
424 scheduler. It is guaranteed that when signal occurs the scheduler
425 is not locked, and thus new tasks can be safely added to the
428 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
429 to silc_schedule_internal_init and silc_schedule_internal_uninit.
430 Added new platform specific routines
431 silc_schedule_internal_signals_[un]block and
432 silc_schedule_internal_signal_[un]register.
434 Added new functions to SILC Schedule API:
435 silc_schedule_signal_[un]register. Each signal that application
436 is going to use should be registered to the scheduler.
438 Affected files are lib/silcutil/silcschedule.[ch],
439 lib/silcutil/*/silc*schedule.c.
441 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
443 * Check for unauthenticated client and server in the
444 silc_server_new_client and silc_server_new_server functions.
445 Affected file silcd/packet_receive.c.
447 * Added function silc_string_is_ascii to check whether given
448 string is 7-bit ASCII string. Affected files are
449 lib/silcutil/silcutil.[ch].
451 * Added function silc_id_is_valid_server_id into the
452 silcd/serverid.c and added checking for valid Server ID's in
453 silc_server_new_server. The Server ID must always be based
454 on the server's public IP address.
456 * Added logging of DISCONNECT packet message in the server.
457 Affected file silcd/server.c.
459 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
461 * Changed all library interfaces that use Global RNG to also
462 accept SilcRng as argument. Affected files are
463 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
464 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
465 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
466 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
469 * Added function silc_pkcs_generate_key to the
470 lib/silccrypt/silcpkcs.[ch] for applications so that they
471 don't need to do pkcs->pkcs->init calls anymore.
473 * Remove SilcSocketConnection from the SFTP API since it really
474 wasn't needed there. The application has the information
475 saved in its contexts anyway and the SFTP layer doesn't need
476 know about it. Affected files lib/silcsft/silcsftp.h and
477 lib/silcsftp/sftp_[server/client].c.
479 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
480 The SilcSimContext is not SilcSim.
482 * Fixed possible buffer overflows in silc_id_render in the
483 lib/silcutil/silcutil.c.
485 * On EPOC the global crypto module lists are not used at all
486 in the crypto library. Added support for using the constant
487 algorithm list on EPOC. Affected files are
488 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
491 * Fixed the handling of third parameter of KICKED notify, since
492 it was mistakenly updated to SILC Protocol 1.0 even though it
493 is to be included in 1.1. Since it is not in 1.0 it is not
494 mandatory, and this fix now handles it only if it is provided,
495 and it is not error if it is not provided. Affected file
496 lib/silcclient/client_notify.c.
498 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
500 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
501 client. Affected file irssi/src/silc/core/client_ops.c.
503 * Merged with Irssi 0.8.4 from irssi.org CVS.
505 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
507 * Check for valid socket connection in client entries before
508 sending any messages. Fixes a crash, but doesn't fix some
509 other underlaying bug that is lurking there. Affected
510 file silcd/packet_send.c.
512 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
514 * $usermode, $cumode and $cumode_space expandos shouldn't do
515 anything with non-SILC server records. Affected file
516 irssi/src/silc/core/silc-expandos.c
518 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
520 * Fixed the silc_net_check_[host/local]_by_sock to support
521 IPv6 bound sockets as well. Now they can return IPv6 addresses
522 as well. Affected file lib/silcutil/silcnet.c.
524 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
525 Affected lib/silcutil/unix/silcunixnet.c.

534 hash public keys and compare public keys in hash table. Affected
535 file lib/silcutil/silcutil.[ch].
537 * Added support for specifying multiple public keys for Client
538 connection section in server configuration file. This makes it
539 possible to accept multiple public keys from same host, or to
540 make a section that accepts any incoming host, and have the
541 accepted public keys listed in the section.
543 Added functions silc_sever_[find/get]_public_key, added the
544 support for this actually to all connection sections but only
545 the Client section is currently allowed to specify multiple

630 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
632 * Added `prefer_ipv6' argument to the functions
633 silc_net_gethostbyname[_async]. If it is TRUE it will return

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

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

794 * Added new configuration options and blocks:
795 keepalive_secs, reconnect_count, reconnect_interval,
796 reconnect_interval_max, reconnect_keep_trying and
797 require_reverser_lookup. Added ConnectionParam block, and
798 implemented the connection parameters when connecting as
799 initiator and when accepting connections as responder.

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

838 authentication to be set at the same time.
840 Added `prefer_passphrase_auth' setting in config file which
841 can be used to set to prefer passwd auth if both passwd and
842 public key is set. If not set, public key is preferred.
843 This has effect only when being initiator (responder will try
846 Added support for authentication with passphrase and public key
847 at the same time. The passphrase is tried first always since
848 it is faster to check.
850 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
852 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

898 * Fixed the file transfer's key agreement payload to include
899 zero port also if the hostname is NULL because it could not
902 Call file transfer monitor callback now also if error occurs
903 during key agreement protocol.
905 Changed the silc_client_file_send interface to return the
906 SilcClientFileError instead of session id. The session ID
907 is returned into pointer provided as argument.
909 Check that the file exists locally before sending the
910 file transfer request at all.
912 Affected file lib/silcclient/client_ftp.c, silcapi.h.

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

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

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

1002 * Fixed the WHOWAS command's reply sending to support the
1003 lists correctly. Affected file silcd/command.c.
1005 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1007 * When sending JOIN command to router for processing the
1008 sender's old command identifier was not saved back to the
1009 sender's command context, fixed now. The affected file is
1012 * Create the key in JOIN command of the router did not return
1013 the channel key, added check for this. Affected file is
1016 * Fixed a channel ID update bug in JOIN command reply. Do
1017 not directly upgrade the ID but call the function
1018 silc_idlist_replace_channel_id if the ID was changed.
1019 Affected file silcd/command_reply.c.
1021 * Fixed memory leaks from command calling if it would fail.
1022 Affected file silcd/command.c.

1049 functions. Affected file silcd/server.c.
1051 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1052 which ID was changed. This way the router will send the
1053 user list for the channel again, and server won't be in
1054 desync in some rare circumstances. Affected file is
1055 silcd/packet_receive.c.
1057 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1072 file for application programmers to quickly start using
1073 the SilcClientOperation functions in their application.
1074 Updated the lib/silcclient/README as well to tell about this
1075 nice file made available.
1077 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1079 * Call silc_server_remove_from_channels when removing client
1080 entry when NO_SUCH_CLIENT_ID was received. Affected file
1081 is silcd/command_reply.c.
1083 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1085 * Added server & router operator statistics updating. Affected
1086 file silcd/packet_receive.c and silcd/command.c.
1088 * Fixed the SERVER_SIGNOFF notify handling on normal server
1089 not to save the history information for clients. Same was
1090 fixed earlier in remove_clients_by_server function, but not
1091 here. Affected file silcd/packet_receive.c.
1093 * Raised the default connection-retry count from 4 to 7 in
1094 server. Affected file silcd/server.h.
1096 * Cancel any possible reconnect timeouts when we start the
1097 key exchange. Affected file silcd/server.c.
1099 * Do not reconnect on connection failure when SCONNECT was
1100 given. Affected files silcd/server.[ch].
1102 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1104 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1106 * Fixed the NICK command to always give the unformatted
1107 nickname to the one giving the NICK command. If unformatted
1108 nickname is cached already it will be formatted and the
1109 local entry will always get the unformatted nickname.
1110 Affected file lib/silcclient/idlist.c.
1112 * Fixed some double frees from client library commands.
1113 Affected file is lib/silcclient/command.c.
1115 * Fixed CUMODE command in server to assure that no one can
1116 change founder's mode than the founder itself, there was a
1117 little bug. Affected file silcd/command.c.
1119 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1121 * Removed the SilcClientCommandDestructor from the client
1122 libary, it is not needed anymore. Affected files are
1123 lib/silcclient/silcapi.h, command[_reply].[ch],
1124 client_notify, idlist.c.
1126 * Fixed GETKEY command to first resolve client, and then
1127 resolve the server only if the client was not found, instead
1128 of resolving both at the same time. Affected file is
1129 lib/silcclient/command.c.
1131 * Added silc_client_start_key_exchange_cb and lookup the
1132 remote hostname and IP address before starting the key
1133 exchange with server. The affected file is
1134 lib/silcclient/client.c.
1136 * The server's public key is now saved using the IP address
1137 of the server and not the servername for the filename.
1138 The hostname public key filename is checked as an fall back
1139 method if the IP address based filename is not found.
1141 Fixed the GETKEY command to save the fetched server key
1142 in correct filename.
1144 Print the remote server's hostname now when new key is
1145 received during connection process. Affected file is
1146 irssi/src/silc/core/client_ops.c.
1148 * Return always our own public key to the client if it asks
1149 for it with GETKEY command. Affected file silcd/command.c.
1151 * Removed the use_auto_addr variable from default config
1152 file since it was in wrong section. Affected file is
1155 * Fixed TOPIC_CHANGE notification to not route it when it
1156 was sent using silc_server_send_notify_to_channel function.
1157 Affected file silcd/command.c.
1159 * Fixed silc_server_send_notify_kicked to send the kicker's
1160 Client ID also, it was missing. Affected files are
1161 silcd/command.c, silcd/packet_send.[ch].
1163 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1165 * Do not save client history information in SERVER_SIGNOFF.
1166 Fixes the bug in normal server that it does not detect
1167 the client becoming valid after the server becomes back
1168 online. Affected file silcd/server_util.c.
1170 * Added `sock_error' field into the SilcSocketConnection
1171 context. When error occurs during socket operation (read
1172 or write) the error is saved. Added also new function
1173 silc_socket_get_error to return human readable socket error
1174 message. Affected files are lib/silcutil/silcsockconn.[ch],
1175 lib/silcutil/unix/silcunixsockconn.c, and
1176 lib/silcutil/win32/silcwin32sockconn.c.
1178 * The server now prints the socket error message in the
1179 signoff for client. Affected file silcd/server.c.
1181 * Fixed the `created' channel information sending from router
1182 to server in JOIN command. Checks now whether the channel
1183 really was created or not and set it according that.
1185 Fixed the JOIN command to use the client entry's current
1186 ID during the joining procedure instead of the one it sent
1187 in the command (it is checked though), since it can change
1188 between the packet processing and command processing, and
1189 would just case unnecessary pain in the client end. Affected
1190 file silcd/command.c.
1192 * Fixed a channel key payload sending to use correct channel
1193 ID when the server was forced to change the channel's ID by
1194 router. Router sent the key payload with the old Channel ID.
1195 Affected file silcd/packet_receive.c.
1197 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1199 * Call silc_server_save_channel_key only if the key payload
1200 was provided in the JOIN command's command reply. Affected
1201 file silcd/command_reply.c.
1203 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1205 * Fixed silc_mp_sizeinbase to return the value correctly with
1206 MPI. Affected file lib/silcmath/mp_mpi.c.
1208 * Fixed the stop_server signal to correctly stop the scheduler
1209 and gracefully stop the server when SIGTERM or SIGINT signals
1210 are received. Affected file silcd/silcd.c.
1212 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1214 * Simple handling of TERM and HUP signals. Also added some log
1215 flushing call around. Affected file is
1218 * Fixed small bugs in silclog.c. Now buffering output will take
1219 effect after 10 seconds since startup: This will ensure that
1220 no important startup messages are lost. Also output redirection
1221 will preserve original format ([Date] [Type] message).
1222 Affected file is lib/silcutil/silclog.c.
1224 * Added two options to the config file, in the logging section:
1225 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1226 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1228 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1230 * Do not print the warning about log files not being initialized
1231 more than once to avoid excess logging. Affected file is
1232 lib/silcutil/silclog.c.
1234 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1235 the SIM copying in make install in Makefile.am.pre.
1237 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1239 * Rewritten silclog APIs. Globally interesting changes follows:
1240 silc_log_set_files() changed to silc_log_set_file().
1241 silc_log_set_callbacks() changed to silc_log_set_callback().
1242 ROBOdoc documented silclog header file.
1243 SilcLogCb now returns bool to wether inihibit the default
1244 handler or not (to keep the old behaviour return always TRUE).
1245 The new APIs should also fix the problem of the
1246 silcd_error.log file that was written in the current directory.
1249 Log files streams will remain opened after silc_log_set_file()
1250 call, means less CPU usage notably on high traffic servers.
1251 File streams are now full buffered, and flushed to the disk
1252 every 5 minutes, lesses HD activity and CPU usage.
1253 Messages can be redirected, allowing admins to configure
1254 one single logfile for all server messages.
1255 the silc_log_quick global variable to activate fast-logging.
1256 Affected files lib/silcutil/silclog.[ch]
1258 * Changed some code to conform new silclog APIs. Affected
1259 files are doc/example_silcd.conf.in, silcd/server.c
1260 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1263 * Fixed a memory leak that could occur in some situations.
1264 Affected file silcd/serverconfig.c.
1266 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1268 * Added the silc_client_del_client to remove the client from
1269 all channels as well. Affected file lib/silcclient/idlist.c.
1271 * Fixed the client library to correctly remove the client
1272 from all channels when the client entry is being destroyed.
1273 Affected file lib/silcclient/client_notify.c, command.c.
1275 * Added auto-nicking support to the client library. If the
1276 applicatio now sets client->nickname it will be sent to the
1277 server after connecting by the library. This way for example
1278 SILCNICK (or IRCNICK) environment variables will have effect
1279 and always change the nickname automatically to whatever
1280 it is wanted. Affected file lib/silcclient/client.[ch].
1282 * Renamed silc_server_command_bad_chars to the
1283 silc_server_name_bad_chars and moved it to the
1284 silcd/server_util.[ch]. Added also new function
1285 silc_server_name_modify_bad to return nickname that
1286 includes bad characters as new nickname without those
1287 bad characters. This check and modify is now used in
1288 silc_server_new_client when the username is initially set
1289 as nickname, so it must be checked to be valid nickname.
1290 Affected file silcd/packet_receive.c.
1292 * The nickname length is now taken from the packet for real
1293 and not trusted to strlen() since it clearly can return
1294 wrong length for nickname including bad characters. This
1295 also applies to channel names. Affected file silcd/command.c.
1297 * Removed the lib/silcsilm/modules directory. Modules are now
1298 compiled into the lib/silcsim. Fixed the copying of the
1299 modules to follow symbolic links in Makefile.am.pre.
1301 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1303 * Fixed silc_string_regexify list creation. Fixes bugs with
1304 BAN and INVITE commands in server. The affected file is
1305 lib/silcutil/unix/silcunixutil.c.
1307 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1309 * Removed the command destructor entirely from the server's
1310 command and command reply routines. It is not needed, and
1311 its usage was buggy and caused crashes. Affected files are
1312 silcd/command[_reply].[ch].
1314 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Cancel protocol and NULL sock->protocol if timeout
1317 occurred during protocol. Affected file silcd/server.c.
1319 * Cancel protocol timeouts always before calling the final
1320 callback, to assure that after final callback is called
1321 no other state will be called for the protocol anymore.
1322 Affected file silcd/protocol.c.
1324 * Print error log if incoming connection configuration could
1325 not be found. Affected file silcd/server.c.
1327 * Fixed JOIN command to correctly save the founder mode
1328 to the client on normal SILC server, when the channel
1329 was created by the router. Affected file silcd/command.c.
1331 * Fixed LIST command (hopefully) to send correct reply
1332 packets. Affected file silcd/command.c.
1334 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * The silc_packet_receive_process now returns FALSE if the
1337 read data was invalid packet, and TRUE if it was ok.
1339 The server now checks that if unauthenticated connection
1340 sends data and its processing fails the server will close
1341 the connection since it could be a malicious flooder.
1343 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1345 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * Make sure the warning about error opening a log file is
1348 printed only once and not everytime it fails (produces
1349 too much useless log). Affected file lib/silcutil/silclog.c.
1351 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1353 * Made the silc_server_daemonise() function more readable.
1354 Affected file silcd/server.c.
1356 * Pid file is now optional, the user may comment it out from
1357 the config file. Removed define SILC_SERVER_PID_FILE, we
1358 don't need a default any longer. Affected file
1359 configure.in.pre, lib/Makefile.am.pre.
1361 * Make some use of the pid file. The server now dies at startup
1362 if it detects a valid pid file on his path. The server would
1363 die anyway in this circumstance, because of the bind() failure.
1364 Affected file silcd/silcd.c.
1366 * No longer compiling lib/dotconf.
1368 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Fixed JOIN command parsing not to crash. Affected file
1371 lib/silcclient/command.c.
1373 * Fied the NICK_CHANGE notify to add the new client entry
1374 even it is resolved. This removes an <[unknown]> nick
1375 thingy bug in the client. Affected file is
1376 lib/silcclient/client_notify.c.
1378 * Do not try to allocate 0 bytes (efence does not like it)
1379 in lib/silccore/silccomand.c when encoding payload.
1381 * Do not take IRCNICK as nickname in Irssi SILC client since
1382 it is not possible to set nickname before hand connecting
1383 the server (TODO has an entry about adding auto-nicking
1386 * Changed the silc_server_command_pending to check whether
1387 there already exists an pending entry with the specified
1388 command, command identifier and pending callback. This is
1389 to fix IDENTIFY and WHOIS related crashes that may register
1390 multiple pending commands with same identifier. Affected
1391 file silcd/command.c.
1393 * Fixed the server to reconnect to the router even if it
1394 was already reconnecting and EOF was received. This to
1395 fix a possibility that the server wouldn't ever try to
1396 auto-reconnect to the router. Affected file silcd/server.c.
1398 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Fixed the server's password authentication to use the
1401 length of the locally saved password, and not the one
1402 sent in the packet. Affected file silcd/protocol.c.
1404 * Fixed same password authentication problem in the
1405 Authentication Payload handling routines in
1406 lib/silccore/silcauth.c.
1408 * Yet another password authentication problem fixed with
1409 channel password handling in silcd/command.c.
1411 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * If first character of string in silc_parse_userfqdn is '@'
1414 then do not parse it. Affected file is
1415 lib/silcutil/silcutil.c.
1417 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Fixed minor bug in IDENTIFY command reply sending, which
1420 caused various weird problems during JOIN when it was
1421 resolving names for users. Affected file silcd/command.c.
1423 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Fixed the IDENTIFY command reply sending to chech better valid
1426 clients. It was possible to send incomplete list of replies.
1427 Affected file silcd/command.c.
1429 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1431 * Added silc_client_command[s]_[un]register functions now to
1432 dynamically register the commands in client library. Removed
1433 the static table of commands. This allows the client library
1434 to call commands without causing the application to know about
1435 what commands library has called.
1437 Removed the INFO command reply kludge to detect when the command
1438 was called by library. Now library use its own command reply
1439 function for INFO command.
1441 Added function silc_client_command_call to call a command.
1442 Application can use it to call command, not access the structure
1445 Now all commands that are sent by the client library (not
1446 explicitly sent by application) use own command reply functions.
1448 Affected files around lib/silcclient/ and in
1449 irssi/src/silc/core/.
1451 * Fixed the WHOIS command reply sending to chech better valid
1452 clients. It was possible to send incomplete list of replies.
1454 Fixed the WHOIS and IDENTIFY to send the request to router
1455 if normal server did not do it and did not find any results.
1457 Affected file silcd/command.c.
1459 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Moved the internal data from SilcClient context into its
1462 own file, not accesible to application. Affected files
1463 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1464 and other files in client library.
1466 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Added doc/examples installation target in Makefile.am.pre.
1471 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1474 commands the found client entry will be removed from the
1475 cache, after notifying application about the error. Affected
1476 file lib/silcclient/command_reply.c.
1478 * Changed the /MSG to check for exact nickname user gave, and
1479 not let `nick' match `nick@host' if it is only one found. Now,
1480 user must type the exact nickname (like nick@host2) even if
1481 there are no more than one same nicks found. This is to avoid
1482 a possibility of sending nickname to wrong nickname since
1483 `nick' could match `nick@host'. Affected file is
1484 irssi/src/core/silc-servers.c.
1486 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Do not print "you are now server operator" or similar when
1489 giving /away command. Affected files are
1490 irssi/src/silc/core/client_ops.c, silc-servers.h.
1492 * Made the silc_server_command_pending_error_check to send
1493 the same command reply payload it received back to the
1494 original sender of the command. This way all arguments
1495 that was received by the server will be received by the
1496 client too. Affected file silcd/command.c.
1498 * Added the silc_idcache_add to return the created cache entry
1499 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1501 * Add global clients to expire if they are not on any channel.
1502 This is because normal server will never know if they signoff
1503 if they are not on any channel. The cache expiry will take
1504 case of these entries. This is done by normal servers only.
1505 The affected files are silcd/command_reply.c,
1506 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1508 * If server receives invalid ID notification for WHOIS or
1509 IDENTIFY and the ID exists in the lists, it is removed.
1510 Affected file silcd/command_reply.c.
1512 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1513 in client then client entry that it matches is searched and
1514 the nickname is printed on the screen for user. Affected
1515 file irssi/src/silc/core/client_ops.c.
1517 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Use cache entry expire time in the LIST command reply to
1520 purge old entries from the cache after the LIST command
1521 reply has been received. This way we don't have non-existent
1522 entries in the cache for too long. Affected file is
1523 silcd/command_reply.c.
1525 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1527 * If we are normal server, and we've not resolved client info
1528 in WHOIS or IDENTIFY from router, and it is global client,
1529 we'll check whether it is on some channel. If it is not
1530 then we cannot be sure about its validity and will resolve it
1531 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1532 file silcd/command.c.
1534 * Search channel by name (if possible) rather than by ID
1535 in IDENTIFY command's command reply. Affected file is
1536 silcd/command_reply.c.
1538 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1540 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1541 Updated specs and implemented it. Affected file silcd/command.c,
1542 silcd/packet_send.c and silcd/packet_receive.c.
1544 * Implemented the <founder auth> payload handling in the JOIN
1545 command. If provided all conditions for channel joining
1546 except requirement to provide correct passphrase can be
1547 overrided by the channel founder. Updated the protocol specs.
1548 Affected file silcd/command.c.
1550 Added support for founder auth in JOIN command in client
1551 library. Fixed the parsing of the JOIN command now to support
1552 all options as they should be. The affected file is
1553 lib/silcclient/command.c.
1555 * Optimized the WHOIS and IDENTIFY commands to send the request
1556 to router only if it includes nicknames or other names. If
1557 they include only IDs then check the local cache first before
1558 routing. Affected file is silcd/command.c.
1560 * Added channels topic announcements. Affected file is
1561 silcd/packet_receive.c and silcd/server.c.
1563 * Fixed the silc_server_send_notify_topic_set to really destine
1564 the packet to channel. Affected file silcd/packet_send.c.
1566 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1567 library. Affected file lib/silcclient/client_notify.c.
1569 * Added UMODE announcements. Affected file silcd/server.c.
1571 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Memory leak fixes in:
1575 lib/silcutil/silcsockconn.c
1576 lib/silcske/silcske.c
1577 lib/silcske/groups.c
1579 lib/silccrypt/silcpkcs.c
1580 lib/silccore/silccommand.c
1581 lib/silccore/silcidcache.c
1586 * ROBOdoc documented the lib/silcske/groups.h file and a
1587 bit changed the interface for better.
1589 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1591 * Update the client entry context in the ID cache after
1592 nick change. Affected file lib/silcclient/command.c.
1593 Fixes the CUMODE command when regaining founder privileges,
1594 and a little WHOIS problem.
1596 * Fixed silc_net_gethostbyname to correctly call the
1597 inet_ntop. Affected file lib/silcutil/silcnet.c.
1599 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1601 * Added IPv6 support checking to the configure.in.pre, added
1602 also --enable-ipv6 option to override the check. Affected
1603 file configure.in.pre.
1605 * The silc_thread_create now calls the start function
1606 directly if threads support is not compiled in. Removes
1607 ugly #ifdef's from generic code. Affected files are
1608 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1610 * Added silc_net_gethostby[name/addr]_async to asynchronously
1611 resolve. Affected files are lib/silcutil/silcnet.[ch].

1622 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1623 routines. Added silc_net_is_ip[4/6]. Affected file is
1624 lib/silcutil/unix/silcunixnet.c. All routines that take
1625 address as argument now supports both IPv4 and IPv6 addresses.
1627 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1629 * Fixed LIST command reply sending in server. Affected file
1632 * Server now sends the kicker's client ID in the KICK notify
1633 to the kicked client. Affected file silcd/command.c.
1635 * The client library now parses the kickers client ID and
1636 UI displays it. Affected files lib/silcclient/client_notify.c
1637 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1639 * Made all payload parsing function prototypes consistent.
1640 They all take now const unsigned char * and uint32 pair as
1641 the payload data instead of SilcBuffer. Changes all around
1642 the source tree. Other unsigned char* -> const unsigned char*
1643 changes around the tree as well.
1645 * Optimized SFTP client and server packet sending not to
1646 allocate new buffer for each packet but to recycle the
1647 first allocated buffer. Affected files are
1648 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1650 * Optimized the SFTP client to use SilcList instead of
1651 SilcDList for requests, because it is faster. Affected file
1652 is lib/silcsftp/sftp_client.c.
1654 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1655 into lib/silccore/silcid.[ch].
1657 Renamed silcpayload.[ch] into silcargument.[ch].
1659 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * If client entry is deleted with active key agreement
1662 session, abort the session.
1664 The silc_client_abort_key_agreement now calls the completion
1665 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1667 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1670 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1672 * Don't use __restrict in older GCC's. Affected file is
1673 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1675 * silc_net_localhost now attempts to reverse lookup the
1676 IP/hostname. Affected file lib/silcutil/silcnet.c.
1678 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1679 command. It can be used to gain founder privileges at
1680 the same time when joining the channel.
1682 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1683 kicker's client ID as well. Updated protocol specs.
1685 Defined that the server must send SILC_COMMAND_IDENTIFY
1686 command reply with error status to client who sent
1687 private message with invalid client ID.
1689 Updated the protocol specification.
1691 * Added silc_server_send_command_reply to send any
1692 command reply. Affected file silcd/packet_send.[ch].
1694 * Added silc_id_payload_encode_data to encode ID payload
1695 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1697 * The server now send IDENTIFY command reply with error
1698 status if client ID in private message is invalid. Affected
1699 file silcd/packet_receive.c.
1701 * Save the server key file with server's IP address in
1702 the filename instead of hostname. The affected file is
1703 irssi/src/silc/core/client_ops.c.
1705 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1710 * Added libtool support for compiling shared objects in
1711 lib/silcsim. Affected file configure.in.pre and
1712 lib/silcsim/Makefile.am. Original patch by cras.
1714 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Pid file configuration, and server's config file fixes
1717 patch by toma. Updated CREDITS file.
1719 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1721 * Fixed silc_client_channel_message to not try to decrypt
1722 the message twice if it resolved the destination client
1723 information. This could cause of dropping one channel
1724 message. Affected file lib/silcclient/client_channel.c.
1726 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1729 lib/silcclient/client.c. This function is used when the SILC
1730 Client is run under some other scheduler, or event loop or
1731 main loop. On GUI applications, for example this may be
1732 desired to used to run the client under the GUI application's
1733 main loop. Typically the GUI application would register an
1734 idle task that calls this function multiple times in a second
1735 to quickly process the SILC specific data.
1737 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1739 * Fixed silc_server_drop() for dropping the supplementary
1740 groups as well, this could cause a security hole on some
1743 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1748 * Write PID file after dropping privileges. Added -F option
1749 to run server on foreground. A patch by debolaz.
1750 Affected files silcd/server.c, silcd/silcd.c.
1752 * Fixed MOTD to return the MOTD file server name. Affected
1753 file silcd/command.c.
1755 * Added INFO command reply handling to the Irssi SILC Client.
1756 Affected file irssi/src/silc/core/client_ops.c.
1758 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Fixed the silc_idcache_list_* routines to really support
1761 the dynamic list. Fixes a crash. Affected file is
1762 lib/silccore/silcidcache.c.
1764 * Fixed the LIST command reply to really call LIST command's
1765 pending callbacks. Affected file silcd/command_reply.c.
1767 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Update conn->local_entry->nickname after giving NICK
1770 command. Affected file lib/silcclient/command.c.
1772 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1774 * Added the [pid] option to the silcd configuration file
1776 Affected files: serverconfig.[ch] and silcd.c
1778 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Save fingerprint in WHOIS command reply in server.
1781 Affected file silcd/command_reply.c.
1783 * Fixed NICK commands pending callback registration.
1784 Affected file lib/silcclient/command.c.
1786 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Use ++server->cmd_ident when sending commands in server,
1789 instead of random number. Affected file silcd/command.c.
1791 * Fixed GETKEY command reply to call actually GETKEY pending
1792 command callbacks. Affected file silcd/command_reply.c.
1794 * A bit stricter check for nicknames. Check for same nickname
1795 in NICK command also. Affected file silcd/command.c.
1797 * Do not call INFO command everytime client ID changes, only
1798 during first connecting. Affected file lib/silcclient/client.c.
1800 * Set the new nickname only after successful command reply for
1801 NICK command is returned by server. Affected file
1802 lib/silcclient/command.c.
1804 * Remove nicknames from nicklist during server_signoff notify.
1805 Should fix /NAMES bit more. The affected file is
1806 irssi/src/silc/core/silc-channels.c.
1808 * Added `fingerprint' field to the SilcIDListData in the
1809 silcd/idlist.h to hold the fingerprint of the client's
1812 Send the fingerprint of the client's public key in WHOIS
1815 Affected files silcd/command.c, and silcd/idlist.[ch].
1817 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1818 create fingerprint from given data.
1820 * Show the fingerprint of the client's public key in WHOIS.
1821 Affected files irssi/src/module-formats.[ch] and
1822 irssi/src/silc/core/client_ops.c.
1824 * Format the multiple same nicknames also during JOIN and
1825 NICK_CHANGE notifys. Affected file is
1826 lib/silcclient/client_notify.c.
1828 * Do not print error on screen for invalid private message
1829 payload since it can come if someone is sending private
1830 messages with wrong key. Affected file
1831 lib/silccore/silcprivate.c.
1833 * Fixed multiple concurrent /PING crash. Affected file
1834 lib/silcclient/command.c.
1836 * Changed the wrong ID encoding. All IP addresses must be
1837 in MSB first order in encoded format. They were encoded
1838 wrong and was in LSB format. Affected files are
1839 silcd/serverid.c, lib/silcutil/silcutil.c.
1841 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1843 * Call the `connect' client operation through the scheduler
1844 in case of error. Affected file lib/silcclient/client.c.
1846 * Call the `failure' client operation even if the error
1847 occurred locally during a protocol. Affected file is
1848 lib/silcclient/protocol.c.
1850 * Added support of sending LIST command to router from normal
1851 server. This way normal server can get list of all channels
1852 in the network too. Fixed the channel list sending in the
1853 server too. Affected files are silcd/command.c, and
1854 silcd/command_reply.[ch].
1856 * Added silc_server_update_channels_by_server and
1857 silc_server_remove_channels_by_server. They are used during
1858 disconnection of primary router and in backup router protocol.
1859 Affected file silcd/server_util.[ch], silcd/server.c and
1860 silcd/server_backup.c.
1862 * Fixed channel adding to global list in IDENTIFY command
1863 reply in server. Affected file silcd/command_reply.c.
1865 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1867 * If the incoming packet type is REKEY or REKEY_DONE process
1868 that packet always synchronously. Fixes yet another MAC
1869 failed error on slow (dialup) connections. Affected file
1870 lib/silcclient/client.c and silcd/server.c.
1872 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Call check_version SKE callback for initiator too. Affected
1875 file lib/silcske/silcske.c.
1877 * Implemented fix for security hole found in the SKE that was
1878 fixed in the specification few days back; the initiator's
1879 public key is now added to the HASH value computation.
1880 Added backwards support for the old way of doing it too, for
1881 old clients and old servers. Affected file is
1882 lib/silcske/silcske.c.
1884 * Enabled mutual authentication by default in SKE. If initiator
1885 is not providing mutual authentication the responder will
1886 force it. This will provide the proof of posession of the
1887 private key for responder. The affected files are
1888 lib/silcclient/protocol.c and silcd/protocol.c.
1890 * Do not cache anymore the server's public key during SKE.
1891 We do mutual authentication so the proof of posession of
1892 private key is done, and if the server is authenticated in
1893 conn auth protocol with public key we must have the public
1894 key already. Affected file silcd/protocol.c.
1896 * Added new global debug variable: silc_debug_hexdump. If
1897 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1898 file lib/silcutil/silclog.[ch].
1900 * Fixed compilation warning due to char * -> const char *.
1901 Affected files lib/silcutil/silcnet.h, and
1902 lib/silccore/silcauth.[ch].
1904 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Fixed CMODE command when new channel key was created. If
1907 the creation failed the old key was removed. Next time giving
1908 same command would crash the server since the old key was
1909 freed already. Affected file silcd/command.c.
1911 * Fixed the silc_server_announce_get_channels to not crash
1912 on reconnect. Affected file silcd/server.c.
1914 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Added silc_log_set_debug_string function to set a regex
1917 string to match for debug output. Only the function names,
1918 or filenames matching the given debug string is actually
1919 printed. This way it is possible to filter out those debug
1920 strings that user is not interested in.
1922 Fixed a bug in silc_string_regexify.
1924 Affected files lib/silcutil/silclog.[ch], and
1925 lib/silcutil/unix/silcunixutil.c.
1927 * Changed the -d options in both server and Irssi SILC client
1928 to take the debug string as argument. Affected files
1929 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1931 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Added silc_hash_babbleprint to create a Bubble Babble
1934 Encoded fingerprint. The encoding is developed by Antti
1935 Huima (draft-huima-babble-01.txt), and it creates human
1936 readable strings out of binary data. Affected file
1937 lib/silccrypt/silchash.[ch].
1939 * Print the babble print now in addition of fingerprint as well
1940 in Irssi SILC client. Affected files are
1941 irssi/src/fe-common/silc/module-formats.[ch],
1942 irssi/src/fe-common/silc/core/client_ops.c.
1944 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Fixed a security problem found in SKE. The initiator's
1947 public key too is now added to the HASH hash value creation
1948 which is signed by the responder to create the SIGN value.
1949 This will prevent anyone in the middle to lie to the responder
1950 about the initiator's public key. If this is done now, the
1951 man in the middle will get caught. Updated the protocol
1954 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Better installation directory handling. Configure module
1957 paths and other paths automatically to example_silc* files
1958 in doc/. A patch by toma.
1960 * Fixed compiler warning from MPI library, and from SILC RNG.
1963 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1964 It can be configured with ./configure. A patch by toma.
1966 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Find correct make to use in prepare-clean. A patch by
1969 toma. Affected file prepare-clean.
1971 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1973 * Added irssi variables use_auto_addr, auto_bind_ip,
1974 auto_bind_port and auto_public_ip.
1976 * Changed the interface for silc_client_send_key_agreement
1977 in lib/silcclient/silcapi.h
1981 irssi/src/silc/core/silc-core.c
1983 lib/silcclient/silcapi.h
1984 irssi/src/silc/core/silc-channels.c
1985 lib/silcclient/client_keyagr.c
1988 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Added silc_pkcs_public_key_compare to compare two
1991 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1993 * Check that the client who set the founder mode on the
1994 channel is the same client that is giving the founder
1995 mode to itself. It is done by comparing the saved public
1996 key (it is saved even in the authentication is passphrase).
1997 Affected file silcd/command.c.
1999 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2001 * Do not process packet for disconnected socket connection.
2002 Affected file lib/silccore/silcpacket.c.
2004 * Process the DISCONNECT packet through scheduler in the
2005 client library. Affected file lib/silcclient/client.c.
2007 * Fixed the silc_client_packet_parse to not to increase
2008 the packet sequence number if the conn->sock and the
2009 current socket connection is not same. This can happen
2010 for example during key agreement when the conn includes
2011 multiple socket connections (listeners). Affected file
2012 lib/silcclient/client.c.
2014 * The sender of the file transfer request now provides also
2015 the pointer (listener) for the key exchange protocol. If
2016 the listener cannot be created then it sends empty key
2017 agreement and lets the receiver provide the listener.
2019 Added `local_ip' and `local_port' arguments to the
2020 silc_client_file_send. If they are provided they are used,
2021 if not then it will attempt to find local IP address, if
2022 not found or bind fails then the remote client will provide
2025 Affected files are lib/silcclient/client_ftp.c and
2026 lib/silcclient/silcapi.h.
2028 * Extended the FILE SEND command to support defining the
2029 local IP and port for key exchange listener. They are
2030 optional. Affected file irssi/src/silc/core/silc-servers.c.
2032 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Defined to WHOIS command reply the sending of fingerprint
2035 of the client's public key (if the proof of posession of the
2036 corresponding private key is verified by the server).
2037 Updated to the protocol specification.
2039 * Added support of receiving the client's public key's
2040 fingerprint in command reply in client library. Affected
2041 file is lib/silcclient/command_reply.c, and
2042 lib/silcclient/idlist.[ch].
2044 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Do not send over 128 chars long nickname to the server
2047 in NICK command. Affected file lib/silcclient/command.c.
2049 * Do not send over 256 chars long channel names to the server
2050 in JOIN command. Affected file lib/silcclient/command.c.
2052 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Assure that silc_server_close_connection cannot be called
2055 twice for same socket context. Affected file is
2058 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Send error message to application if opening file for
2061 writing during file transfer fails. Affected file is
2062 lib/silcclient/client_ftp.c.
2064 Remove all file transfer sessions for a client that we're
2065 removing from ID cache.
2067 Affected file is lib/silcclient/client_ftp.c.
2069 * Fixed silc_net_addr2bin to return correct address. Affected
2070 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2072 * Fixed file transfer session removing on signoff notify.
2073 Affected file irssi/src/silc/core/silc-servers.c.
2075 * Added the SilcClientFileError to be returned in the monitor
2076 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2077 Affected file lib/silcclient/silcapi.h.
2079 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Fixed a crash in silc_client_ftp_free_sessions and
2082 silc_client_ftp_session_free_client. Affected file
2083 lib/silcclient/client_ftp.c.
2085 * Added `disabled' field in the SilcChannelEntry in the server
2086 to indicate if the server entry is disabled. Affected file
2087 silcd/idlist.h, silcd/command[_reply].c.
2089 * SILC server adds now /var/run/silcd.pid everytime it is
2090 started. Affected file silcd/silcd.c.
2092 * Added silc_server_packet_send_clients to send a packet to
2093 the provided table of client entries. Affected file
2094 silcd/packet_send.[ch].
2096 * Fixed a crash in client resolving in client_prvmsg.c in
2097 client library. Affected file lib/silcclient/client_prvmsg.c.
2099 * Do not actually remove the client directly from ID cache
2100 during SERVER_SIGNOFF, but invalidate it. This way we
2101 preserve the WHOWAS info for the client. Affected file
2102 silcd/server_util.c.
2104 * Fixed SERVER_SIGNOFF notify handling in the server. The
2105 server is now able to process incoming SERVER_SIGNOFF notify
2106 for a server that it doesn't even know about. It will remove
2107 the clients provided in the notify. Affected file
2108 silcd/packet_receive.c.
2110 * Check for partial packet in data queue after every packet that
2111 was found from the queue. Return and wait for more data if
2112 there is partial data in queue. Affected file is
2113 lib/silccore/silcpacket.c.
2115 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Added SilcClietFileError enum to indicate error in
2118 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2119 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2120 Affected files lib/silcclient/silcapi.h and
2121 lib/silcclient/client_ftp.c.
2123 * Check that newsize in silc_buffer_realloc is larger than
2124 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2126 * Added better monitor of file transfers. It now monitors
2127 key agreement protocol during the file transfer too. Added
2128 error reporting too. Affected files
2129 irssi/src/silc/core/silc-servers.c,
2130 irssi/src/fe-common/silc/module-formats.[ch].
2132 * Wrote a help file for FILE command.
2134 * Added silc_rng_global_get_byte_fast to get not-so-secure
2135 random data as fast as possible. Random data is read from
2136 /dev/urandom if available and from the SILC RNG if not
2137 available. It is used in padding generation. Affected file
2138 lib/silccrypt/silcrng.[ch].
2140 * All packets in client library are now processed synchronously.
2141 Optimized packet processing a lot. Affected file
2142 lib/silcclient/client.c.

2145 now in server, to optimize packet processing. Affected file
2148 * Include files are installed now only in Toolkit distribution
2149 if make install is given. Affected files: all Makefile.am's.
2151 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Assure that silc_client_notify_by_server_resolve does not
2154 resolve the client information multiple times. If it cannot
2155 be found by the first it cannot be found at all. Affected
2156 file lib/silcclient/client_notify.c.
2158 * Fixed WHOWAS command reply calling. Affected file
2159 lib/silcclient/command_reply.c.
2161 * Removed all references to silc_idlist_get_client from the
2162 Irssi SILC client since that call is internal call used by
2163 the library. The Irssi SILC client will use now client
2164 retrieval functions found in silcapi.h.
2166 * Fixed a bug in resolving nickname info before sending
2167 private message. It used freed memory. Affected file
2168 irssi/src/silc/core/silc-servers.c.
2170 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Assure my_channels statistics cannot go negative in server.
2173 Affected files silcd/server.c, silcd/server_util.c.
2175 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2189 * Added silc_net_localip to return local host's IP address.
2190 Affected file lib/silcutil/silcnet.[ch].
2192 * If key exchange or rekey protocol is active for a connection
2193 parse all packets syncronously since there might be packets
2194 in packet queue that we are not able to process without first
2195 processing packets before them. Affected file silcd/server,
2196 lib/silcclient/client.c.
2198 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2199 whether library should continue processing the packet.
2200 Affected file lib/silccore/silcpacket.h.

2235 * Resolve the client info when received private message or
2236 channel message for a client which nickname we don't know.
2237 Affected files lib/silcclient/client_prvmsg.c and
2238 lib/silcclient/client_channel.c.
2240 * Do not crash in /KEY if client is not connected. Affected
2241 file irssi/src/silc/core/silc-channels.c.
2243 * Added SilcClientStatus field to the SilcClientEntry in the

2246 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2247 is incomplete and is being resolved, it won't be resolved
2250 Make sure also that USERS command reply does not resolve
2251 twice information. Affected file is
2252 lib/silcclient/command_reply.c.
2254 Make sure that silc_client_get_clients_by_list does not
2255 resolve twice same information.
2257 * Check for valid client->id in the silc_server_free_client_data.
2258 Affected file silcd/server.c.
2260 * Fixed /GETKEY nick@server not to crash if the server entry
2261 is not found. Affected file lib/silcclient/command.c.
2263 * Fixed the silc_server_check_cmode_rights to check the
2264 requested modes correctly. Affected file silcd/command.c.

2268 * Better checks for non-printable chars in nick added.
2269 Affected file silcd/command.c.
2271 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Call the silc_server_udpate_servers_by_server in the
2274 primary router that comes back online in the backup resuming
2275 protocol. Otherwise it routes packets wrong. Affected file
2276 silcd/server_util.[ch], silcd/server_backup.c.
2278 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2281 lib/silcutil/silcbuffmt.[ch].
2283 * Redefined the SILC packet header to include the padding
2284 length. Affected file lib/silccore/silcpacket.[ch].
2286 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2287 length for maximum padding up to 128 bytes). Affected
2288 file lib/silccore/silcpacket.h.
2290 * Removed all backwards support for old 0.5.x MAC thingies.
2291 The SILC packet header change makes it impossible to be
2292 backwards compatible.
2294 * Send the ENDING packet with timeout in the backup resuming
2295 protocol. This is to assure that all routers has connected
2296 to the primary router. Affected file silcd/server_backup.c.
2298 * Changed the RNG to take the first IV from random data. It
2299 used to take it from zero actually. Changed the RNG also
2300 to use /dev/urandom during session. /dev/random is used
2301 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2303 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Changed the SILC packet header to have the first two bytes
2306 (the packet length) encrypted. Affected files aroung the
2307 code tree, lib/silccore/silcpacket.[ch]. Removed the
2308 SilcPacketCheckDecrypt callback. It is not needed anymore
2309 since the silc_packet_receive_process will determine now
2310 whether the packet is normal or special.
2312 * Implemented the unidirectional MAC keys. Affected files
2313 lib/silcske/silcske.c, silcd/protocol.c and
2314 lib/silcclient/protocol.c.
2316 * Implemented the packet sequence number to the MAC computation.
2317 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2318 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2319 lib/silcclient/protocol.c.
2321 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Allow backup router to announce servers. All servers
2324 announced by backup router are added to the global list
2325 automatically. Update hte server's socket to our primary
2326 router also when backup router announces a server.
2327 Affected file silcd/packet_receive.c.
2329 * Do not update the client->router in the function
2330 silc_server_udpate_clients_by_server if the client is on
2331 global list. We might fail to find any specific server
2332 for locally connected clients and local cell clients. They
2333 should still use the `from' and not `to' as client->router.
2334 This fixes backup router resuming protocol. Affected file
2335 silcd/server_util.c.
2337 * Decrease channel statistics count only if the channel
2338 deletion worked. Affected files are silcd/server.c and
2339 silcd/server_util.c.
2341 * Added silc_server_update_servers_by_server to update origin
2342 of all server entries. Used during backup router protocol.
2343 Affected files silcd/server_util.[ch], silcd/server.c. and
2344 silcd/backup_router.c.
2346 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2347 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2348 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2349 lib/silccrypt/silchmac.c.
2351 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Assure that router cannot reroute the same channel message
2354 to the sender. Affected file silcd/packet_receive.c.
2356 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2358 * Made better checks that the channel message is not sent
2359 to the router it came from. Affected file is
2360 silcd/packet_send.c. Fixed memory leak too.
2362 * Announce informations for incoming router connection, but
2363 only after checking if it is replaced by backup router.
2364 Affected file silcd/packet_receive.c.
2366 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Fixed the backup resuming protocol to work in multiple
2369 router environment. Affected file silcd/server_backup.c.
2371 * Route packet only to one router in the function
2372 silc_server_packet_send_to_channel. Affected file is
2373 silcd/packet_send.c.
2375 * Fixed silc_server_send_notify_dest to set the broadcast
2376 flag. Fixed the silc_server_send_notify_topic to actually
2377 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2378 Affected file silcd/packet_send.c.
2380 * Changed the SFTP Filesystem interface. Changed the
2381 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2382 the filesystem operation function. The SilcSFTPFilesystem
2383 is now a context that is allocated by all filesystem allocation
2384 functions and it already includes the operations structure
2385 and filesystem specific context. It is given as argument
2386 now to the silc_sftp_server_start. This made the interface
2387 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2388 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2390 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Changed the backup router adding and getting interfaces
2393 in the server. The router that will be replaced by the
2394 specified backup router is now sent as argument. Affected
2395 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2398 * Added silc_net_addr2bin_ne to return the binary form of
2399 the IP address in network byte order. Affected files
2400 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2402 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Check for existing server ID in silc_server_new_server
2405 and in silc_server_connect_to_router_final and remove the
2406 old entry if it exists. Affected file silcd/packet_receive.c,
2409 * Send the channel message always to only one router, either
2410 in upstream or downstream. Affected file is
2411 silcd/packet_send.c.
2413 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2415 * Wrote the definition of the backup resuming protocol to the
2416 protocol specification.
2418 * Removed one redundant channel key generation from normal
2419 server during joining procedure. Removed one redundant
2420 channel key sending from server to router during joining
2421 procedure. Affected file silcd/command.c.
2423 * Made minor bugfixes to the backup router resuming protocol.
2424 Affected file silcd/server_backup.c, server.c.

2429 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2432 * Implemented the backup resuming protocol that is used to
2433 resume the primary router position in the cell after the
2434 primary router comes back online. Affected files
2435 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2436 and silcd/server_util.[ch].
2438 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Sleep two (2) seconds after sending QUIT command to server.
2441 Affected file lib/silcclient/command.c.
2443 * Assure that if outgoing data buffer is pending do not force
2444 send any data. Affected file silcd/packet_send.c.
2446 * Assure that if outgoing data buffer is pending do not force
2447 send any data. Affected file lib/silcclient/client.c.
2449 * Implemented the backup router support when the primary router
2450 goes down. The servers and routers can now use the backup
2451 router as new primary router without loosing connectivity.
2453 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2456 in the server to indicate disabled entry. All data read
2457 from the connection will be ignored and no data is sent
2458 for entry that is disabled. Affected files are
2459 silcd/idlist.h, silcd/server.c.
2461 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Created SFTP client and server test programs in the
2464 lib/silcsftp/tests directory.
2466 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Implemented memory filesystem (virtual filesystem) for
2469 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2472 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Implemented the SFTP (SSH File Transfer Protocol) to the
2475 lib/silcsftp. It includes SFTP client and SFTP server
2478 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Moved lib/silccore/silcprotocol.[ch] to the
2481 lib/silcutil library.
2483 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2484 take variable argument list pointer as argument. Affected
2485 file lib/silcutil/silcbuffmt.[ch].
2487 * Added silc_buffer_set function that is used to set data
2488 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2489 Affected file lib/silcutil/silcbuffer.h.
2491 * Changed various routines in the core library to use the new
2492 silc_buffer_set instead of allocating new buffer only for
2495 * Added 64-bit value formatting and unformatting support to the
2496 silc_buffer_[un]format routines. Affected file is
2497 lib/silcutil/silcbuffmt.[ch].
2499 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2500 to includes/bitmove.h.
2502 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Fixed channel user mode saving in client library. Affected
2505 file lib/silcclient/command[_reply].c.
2507 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Defined the file transfer to the SILC Protocol. Added
2510 new packet type SILC_PACKET_FTP and defined File Transfer
2511 Payload. The mandatory file transfer protocol is SFTP
2512 (SSH File Transfer Protocol). Affected file in addition
2513 of the internet draft is lib/silccore/silcpacket.h.
2515 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2516 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2517 is used as part of backup router protocol when the primary
2518 router of the cell is back online and wishes to resume
2519 the position as primary router.
2521 * Redefined the MAC generation keys in the protocol. The
2522 same key is not used anymore in both direction. Both
2523 direction will now use different keys for sending and
2524 receiving. This fixes a potential security flaw. This
2525 change causes incompatibilities in the protocol.
2527 * Redefined also the MAC computation from the packet.
2528 An packet sequence number is now added to the MAC
2529 computation. This prevents possible replay attacks against
2530 the protocol. This change too causes incompatibilities
2533 Added `sequence' field to the SilcPacketContext to hold
2534 the current sequence number for the packet.
2536 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Added `created' field to the SilcIDListData in the file
2539 silcd/idlist.h to indicate the time when the entry was
2542 * Added `created' field to the SilcChannelEntry too. Affected
2543 file silcd/idlist.h.
2545 * Added `creation_time' aguments to all the announcement functions
2546 in the server. If it is provided then only the entries that
2547 was created after the provided time frame are actually
2548 announced. Affected file silcd/server.[ch].
2550 * The protocol says that the Channel ID's IP address must be
2551 based on the router's IP address. Added check for this in
2552 the silc_server_new_channel when processing incoming New Channel
2553 Payload. Affected file silcd/packet_receive.c.
2555 * Print out the correct version with --version in SILC client.
2556 Affected file irssi/src/silc/core/silc-core.c.
2558 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2560 * Fixed WHOWAS command to check for completnes of the client
2561 entry always, not just when the command is coming from client.
2562 Affected file silcd/command.c.
2564 * Added new function silc_server_packet_queue_purge to purge the
2565 outgoing data queue to the network. After the function returns
2566 it is guaranteed that the outgoing packet queue is empty.
2567 Affected file silcd/packet_send.[ch].
2569 * Purge the outgoing packet queue in the rekey protocol's final
2570 callback to assure that all rekey packets go to the network
2571 before quitting the protocol. Affected file silcd/server.c.
2573 * Added silc_client_packet_queue_parse as similar function as
2574 in server to the client library. The affected file is
2575 lib/silcclient/client.c.
2577 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Splitted silcd/server.c and created silcd/server_util.[ch]
2580 for utility functions.
2582 * Added new socket flag SILC_SF_DISABLED to indicate that the
2583 connection is open but nothing can be sent to or received from
2584 the connection. Affected file lib/silcutil/silsockconn.[ch].
2585 The checking for disabled socket is checked in the low level
2586 silc_socket_write and silc_socket_read functions.
2588 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Allow only nicknames and channel names that fits into the
2591 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2593 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * When processing JOIN command reply in server check that if
2596 the channel exists in our global list we'll move it the local
2597 list. Affected file silcd/command_reply.c.
2599 * Fixed the check whether client is joined on the channel already
2600 in JOIN command. Affected file lib/silcclient/command.c.
2602 * Fixed the JOIN command reply to check whether the channel
2603 already exists. Affected file lib/silcclient/command_reply.c.
2605 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Added silc_ske_status_string to map the SKE error numbers
2608 to readable strings. The affected files are
2609 lib/silcske/silcske[_status].[ch].
2611 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * Do not show the private channels on the WHOIS channel list
2614 as it is not allowed by the protocol. The affected file is
2617 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2619 * Assure that the packet length digged from the actual packet
2620 is something sensible in the silc_packet_decrypt_rest_special
2621 in lib/silccrypt/silcpacket.c.
2623 * Free and NULL the allocated pointer in silc_hmac_alloc if
2624 the HMAC allocation fails. The affected file is
2625 lib/silccrypt/silchmac.c.
2627 * Print the selected security properties to the log files in
2628 the server. Affected file silcd/protocol.c.
2630 * Add SKE's reference counter even if calling the completion
2631 callback manually. Otherwise it goes negative, although it
2632 does not cause any problems. The affected file is
2633 lib/silcske/silcske.c.
2635 * Remove the client entry with short timeout after giving the
2636 KILL command. Affected file lib/silcclient/command.c.
2638 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2639 case all found clients are already disconnected (WHOWAS would
2640 found them) in the server. Affected file silcd/command.c.
2642 * Update the last_receive (time of last data received) to be
2643 updated only when received private or channel message so that
2644 the idle time showed in WHOIS makes more sense.
2646 * Added boolean field `valid' in to the SilcClientEntry in the
2647 client library to indicate whether the entry is valid or not.
2648 This fixes the nickname change bug on channel when changing
2649 the nickname to be same than the old (like nick to Nick) the
2650 nickname formatter doesn't set the new nick anymore to Nick@host.
2651 Affected file lib/silcclient/idlist.[ch].
2653 * Now actually fixed the nickname changing on disconnection.
2654 Added new function silc_change_nick to the Irssi SILC Client.
2655 Affected file irssi/src/silc/core/client_ops.c,
2656 irssi/src/silc/core/silc-nicklist.[ch].
2658 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2660 * Check that the public key exists in the GETKEY command before
2661 trying to encode it. Affected file silcd/command.c.
2663 * Print some notifications on received public keys with GETKEY
2664 command in the Irssi SILC Client. Affected files are
2665 irssi/src/fe-common/silc/module-formats.[ch],
2666 irssi/src/silc/core/client_ops.c.
2668 * Use IDENTIFY command to resolve the server information in the
2669 GETKEY command instead of INFO command. Affected file
2670 lib/silcclient/command.c.
2672 * All command reply functions in the client library now calls
2673 the pending command reply callbacks even if an error has
2674 occurred. The server has done this a long time and now it was
2675 time to move the client library to this as well. Now all
2676 errors can be delivered back to the pending command reply
2677 callbacks if necessary. Affected files are
2678 lib/silcclient/command[_reply].[ch].
2680 * Change the nickname on disconnection back to the username
2681 because in reconnect the server will enforce it to it anyway.
2682 Affected file irssi/src/silc/core/silc-servers.c.
2684 * Fixed a config file parsing bug in the Irssi SILC client.
2685 Affected file irssi/src/silc/core/clientconfig.c.
2687 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * When printing the channel mode on JOIN, verify that the
2690 channel key and channel's HMAC are valid. Affected file
2691 irssi/src/silc/core/client_ops.c.
2693 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2696 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2697 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2699 * Removed channel key rekey task deleting from the function
2700 silc_server_save_channel_key. Affected file silcd/server.c.
2701 Added explicit timeout task context instead that is used to
2702 delete the task if we are registering a new task before the
2703 new task has elapsed.
2705 * When channel key rekey occurs the client library now saves
2706 the old channel key for a short period of time (10 seconds) and
2707 is able to use it in case some is still sending channel
2708 messages encrypted with the old key after the rekey. Affected
2709 file lib/silcclient/[idlist.h|client_channel.c].
2711 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2713 * Added check to the silc_server_new_id_real to not accept
2714 new ID if it is the sender's own ID. Affected file is
2715 silcd/packet_receive.c.
2717 * Assure that we do not announce ourself or the one we've
2718 sending our announcements when we're router and are announcing
2719 servers to our primary router. Affected file silcd/server.c.
2721 * Fixed silc_server_command_identify_check_client to assemble
2722 correct WHOIS packet. It send corrupted WHOIS packet and
2723 caused problem with router to router connections. Affected
2724 file silcd/command.c.
2726 Fixed also silc_server_command_whois_check the same way
2727 as for the IDENTIFY command.
2729 * Added new SilcIDListStatus to the server in the SilcIDListData
2730 structure. The status now includes the current status of
2731 the entry (like registered, resolved etc.). Affected file
2732 silcd/idlist.[ch]. Defined a bunch of different status types
2733 as well. This replaced the old boolean registered field as well.
2735 Added resolve_cmd_ident field to the SilcClientEntry structure
2736 too so that if the entry is for example being resolved so
2737 another command may attach to the same pending command reply
2738 without requiring to resolve the same entry again. This concept
2739 should optimize the WHOIS and the IDENTIFY resolving under
2740 heavy load by taking away unnecessary resolving for entries
2741 that are being resolved already.
2743 Added support for adding multiple pending commands for one
2744 command idenfier. Affected file silcd/command[_reply].[ch].
2746 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2747 before deleting the data. Otherwise the hash table will have
2748 freed data in comparison functions. Affected file is
2749 silcd/command_reply.c.
2751 * Fixed silc_idlist_replace_client_id to add the new entry to
2752 the cache with NULL nickname. Otherwise there will be invalid
2753 memory as the nickname after the nickname is freed. Affected
2754 file silcd/packet_receive.c.
2756 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2757 saved into wrong slots because the previous number of entries
2758 was not taken into account. Affected file silcd/idlist.c.
2759 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2761 * If we are router and we receive JOIN notify to a channel that
2762 does not have any users then notified client is marked as the
2763 channel founder, as it is it. The affected file is
2764 silcd/packet_receive.c
2766 * Added to the extended hash table API's table_del_*ext functions
2767 the destructor as argument too, so that the caller can decide
2768 which destructor to use or whether to use destructor at all.
2769 Affected file lib/silcutil/silchashtable.[ch].
2771 * Fixed ID Cache purging. It actually deleted the entries from
2772 the hash table after the data was freed. The hash table ended
2773 up comparing freed memory. The affected file is
2774 lib/silccore/silcidcache.c.
2776 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Fixed Irssi SILC client's KILL command's HELP syntax.
2780 * The USERS command now resolves the detailed user information
2781 if the userinfo field is missing. Affected file is
2782 lib/silcclient/command_reply.c.
2784 * Do not print error in silc_file_read if the read file does
2785 not exist. Just silently return NULL. Affected file is
2786 lib/silcutil/silcutil.c.
2788 * Fixed the silc_log_output to not wine about NULL filename
2789 and to not create some bogus " " filename. Affected file is
2790 lib/silcutil/silclog.c.
2792 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Fixed various printing bugs on the user interface in the
2795 Irssi SILC Client. Minor changes that were forgotten from
2798 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Fixed the configure.in.pre and the compilation and distribution
2801 environment to support the new autoconf 2.52. That version is
2802 now required to compile the CVS trunk.
2804 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2806 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2807 to generally parse user@fqdn format strings. Affected file
2808 lib/silcutil/silcutil.c.
2810 * Added nickname_format and nickname_force_format fields to the
2811 SilcClientParams structure. The first one defines the format
2812 for the nicknames that the library will enforce if the receives
2813 multiple same nicknames. The second one is boolean value and
2814 can be used to force the library to always enforce the format
2815 to the nicknames regardles whether there are multiple nicknames
2816 or not. This configurable formatting was employed to flexibly
2817 support accessing multiple nicknames from the user interface.
2818 The userinterface can now set the nicknames to what ever format
2819 they prefer. Affected file lib/silcclient/silcapi.h.
2821 Added function silc_client_nickname_format to the file
2822 lib/silcclient/idlist.c. It performs the nickname formatting.
2824 Added new field `hostname´ to the SilcClientEntry context.
2825 It holds the hostname of the client. Affected file is
2826 lib/silcclient/idlist.h.
2828 * Irssi SILC Client sets the nicknames in nick@hostn format.
2829 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2830 irssi/src/silc/core/silc-core.c.
2832 The WHOIS printing now also shows both the real nickname and
2833 the formatted nickname so that user knows how to access the
2834 user if there are multiple same nicknames cached. Affected
2835 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2836 printing formatting too to take the hostname now as a separate
2837 argument. The Affected file is
2838 irssi/src/fe-common/silc/modules-formats.[ch].
2840 * Changed the silc_client_get_clients_local to accept the formatted
2841 nickname as argument. It accepts the real nickname too but the
2842 formatted nickname can be used to find the true entry from
2843 multiple entries. Affected file lib/silcclient/silcapi.h and
2844 lib/silcclient/idlist.c.
2846 * Added nickname_format_parse field to the SilcClientParams.
2847 It is a callback function provided by the application to parse
2848 the nickname out of the formatted nickname string. The library
2849 calls it to get the nickname from the formatted string. Since
2850 the application generally knows better the format of the nickname
2851 string it parses it instead of the library, even though library
2852 encodes the formatted string. If the callback function is not
2853 provided then the library will use the string as is. The
2854 affected file is lib/silcclient/silcapi.h.
2856 * All the nickname strings passed to the client library in
2857 commands are now expected to be formatted nickname strings.
2858 If the command does not support the formatted nickname string
2859 it will assume that the sent string is the actual nickname.
2860 Affected file lib/silcclient/command.c.
2862 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Added public key authentication support to OPER and SILCOPER
2865 commands in the client library. Affected file is
2866 lib/silcclient/command.c.
2868 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Changed the get_auth_methdod client operation to be asynchronous.
2871 It can be async if the application resolves the authentication
2872 method from the server during the negotiation. Added new
2873 SilcGetAuthMeth completion callback that the application will
2874 call after resolving the authentication method.
2876 Added function silc_client_request_authentication_method that
2877 the application can use to resolve the authentication method
2878 from the server. Added also SilcConnectionAuthRequest callback
2879 that the library will call after the server has replied. The
2880 application can call this function if it does not know the
2881 current authentication method.
2883 Affected files are lib/silcclient/client.c and
2884 lib/silcclient/silcapi.h.
2886 * The Irssi SILC client now automatically resolves the authentication
2887 method incase any configuration information is not present (and
2888 currently there never is). The affected file is
2889 irssi/src/silc/core/client_ops.c.
2891 * Fixed public key authentication from the client library.
2892 Affected file lib/silcclient/protocol.c. Changed also the
2893 protocol specification about the public key authentication in
2894 the connection authentication protocol. The actual data to be
2895 signed is now computed with a hash function before signing.
2897 * Fixed the public key authentication from the server as well.
2898 Affected file silcd/protocol.c.
2900 * Removed the mlock()'s from the memory allocation routines.
2901 Affected file lib/silcutil/silcmemory.c. The ./configure does
2902 not check anymore for the mlock(). Affected file is
2905 * Fixed USERS command in server to allow the execution of the
2906 command for private and secret channels if the client sending
2907 the command is on the channel. Affected file silcd/command.c.
2909 * Fixed silc_client_get_clients_local to return the clients
2910 count correctly. It could return wrong value. Affected file
2911 lib/silcclient/idlist.c.
2913 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2916 types. The assembler optimizations seemed not to like 64-bit
2917 data types. The assmebler optimizations thus are now enabled
2918 also for BSD systems as opposed to only enable them for Linux.
2920 * Do not check for threads at all on BSD systems. Affected
2921 file configure.in.pre.
2923 * Removed -n and -h options from the Irssi SILC Client since
2924 they are not used in silc.
2926 * Fixed the prime generation to assure that the first digit
2927 of the generated random number is not zero since our conversion
2928 routines does not like number strings that starts with zero
2929 digit. If zero digit is seen the random number is regenerated.
2930 This caused some corrupted RSA keys when the zero first digit
2931 was met. Affected file lib/silcmath/silcprimegen.c.
2933 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Fixed WIN32 configuration in the ./configure script.
2936 Fixed to include xti.h on environments that has it.
2937 Patches by Carsten Ilchmann and andrew.
2939 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Changed the silc_id_create_client_id to be collision
2942 resistant. It is now assured that there cannot be created
2943 two same client ID's. I suspect that some weird bugs in
2944 the server were actually caused by duplicate Client IDs.
2945 Affected file silcd/serverid.[ch]. A router receiving
2946 new ID now also assures and informs the sending server
2947 if the ID caused collision.
2949 * Changed the silc_id_create_channel_id to also assure that
2950 there are no collisions.
2952 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2954 * Statement about ignoring the Mutual Authentication flag when
2955 performing rekey with PFS was a bit misleading. It is ignored
2956 if it was set in the initial negotiation, it cannot be even
2957 set in the rekey. Fixed in the ke-auth draft. Started the
2958 new versions of the protocol drafts in the doc/.
2960 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2962 * Fixed a bug in silc_client_command_identify_save when saving
2963 new channel information. The channel name was no duplicated
2964 and caused crash on exit. Affected file is
2965 lib/silcclient/command_reply.c.
2967 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Fixed the getkey command handling in the server. Send just
2970 empty OK reply to the sender if the key could not be fetched
2971 (but everything else was ok, like the key just was not available).
2972 Changed the public key parameter to optional in the protocol
2973 specs so that empty OK reply can be sent. Affected file
2976 Added a message to Irssi SILC client to tell to user if the
2977 server did not return a public key.
2979 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Fixed a channel key regeneration bug. It registered new
2982 timeout tasks exponentially until all system resources were
2983 used. Affected file silcd/server.c.
2985 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Added the SILC Document generator to the scripts/silcdoc.
2988 It can be used to generate the Toolkit Reference Manual out
2989 of the source tree. Internally it will also use the RoboDoc
2990 generator now imported in util/robodoc.
2992 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Added couple of return's in rekey protocol if error orccurred
2995 during the protocol. The execution must be terminated.
2996 Affected file silcd/protocol.c. Also, terminate the protocol
2997 always with timeout.
2999 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * The client's Client ID was created initally from the wrong
3002 nickname (it could have been in format nick@host) in the
3003 silc_server_new_client. Affected file silcd/packet_receive.c
3005 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Added some SILC_LOG_ERROR's to various error conditions
3008 if client could not be added to ID cache. Affected files
3009 silcd/packet_receive.c and silcd/server.c.
3011 * When client's sock->user_data is freed, NULL also the
3012 client->router and client->connection pointers. Added check
3013 for these pointers being NULL to various places around the
3014 code. Affected file silcd/server.c.
3016 * Added client->data.registered == TRUE checks to various
3017 places around the code to assure that unregistered client's
3018 are not handled when it is not allowed. Affected file
3021 * Added `bool registered' fields to all
3022 silc_idlist_[server|client]_get_* routines to indicate whether
3023 the fetched client needs to be registered or not. Affected
3024 file silcd/idlist.[ch].
3026 * Add your own entry as registered to the ID cache in the
3027 server. Affected file server.c.
3029 * Fixed a bug in silc_server_new_server. The SilcServer was
3030 set as the new server's context instead of SilcServerEntry.
3031 This naturally caused some weird bugs.
3033 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Do not delete the channel rekey task when adding it
3036 for in silc_server_create_channel_key.
3038 * Changed the silc_server_create_channel_key to return
3039 TRUE or FALSE to indicate the success of the channel key
3042 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Fixed MSVC++ project files and added missing files to
3045 Makefiles under win32/.
3047 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3049 * Do not add TCP_NODELAY flag if the operating system
3050 does not have it defined. Affected files are
3051 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3053 * Fixed buffer overflow from Irssi SILC Client. Affected
3054 file irssi/src/fe-common/core/themes.c.
3056 * Fixed double free in client library in the file
3057 lib/silcclient/client.c when disconnecting from server.
3059 * Applied double free patch from cras to Irssi SILC client.
3060 Affected files irssi/src/core/[modules/expandos].c
3062 * Fixed the disconnection handling to Irssi SILC Client.
3063 The application must call silc_client_close_connection
3064 in ops->connect client operation in case of failure of
3065 the connection. Affected file is
3066 irssi/src/silc/core/client_ops.c.
3068 * Do not set sock->protocol to NULL in the function
3069 silc_client_close_connection after executing the protocol's
3070 final callback since the sock might not be valid anymore.
3071 Affected file lib/silcclient/client.c.
3073 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Do not enable SILC_THREADS if the linking with libpthread
3076 did not happen. Affected file configure.in.pre.
3078 * Added notion to protocol specification that server must
3079 verify the sent authentication payload with CMODE when
3080 setting the channel founder key. Implemented it to the
3081 server. Affected file silcd/command.c.
3083 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * Added _EXTRA_DIST SILC distribution variable to the
3086 distributions file. It is used to conditionally add extra
3087 files or directories to the specific distribution. Affected
3088 files ./prepare, Makefile.am.pre and distributions.
3090 Removed the `_' from the start of the distribution names.
3093 * Added README.WIN32 for instructions to compile the Toolkit
3096 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Fixed a double free in disconnection in the server. Affected
3099 file is silcd/server.c.
3101 * Fixed the lib/silcske/groups.c to work now also with GMP
3102 MP library. The string conversion did not work when using
3103 specific base and the base is indicated in the string as well.
3105 * Created win32/ directory which now includes MSVC++ specific
3106 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3107 It will appear only in the toolkit distribution
3109 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Changed the key material distribution function in case when
3112 the hash output is too short. The data is now concatenated
3113 a bit differently than it used to. Made the change to the
3114 SKE protocol specification.
3116 * Added better GMP detection to configure.in.pre. A patch
3119 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Fixed a minor bug in SKE that might cause some problem on
3122 some platforms. Affected file lib/silcske/silcske.c.
3124 * Added the cookie checking for initiator in the SKE. It checks
3125 that the responder returns the sent cookie unmodified. The
3126 affected file is lib/silcske/silcske.c. Added new SKE
3127 error type INVALID_COOKIE that can be sent during the
3128 negotiation. Fixed some memory leaks as well.
3130 * Added the "invalid cookie" error message to Irssi SILC client's
3133 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3135 * Added `task_max' field to the SilcClientParams to indicate
3136 the maximum tasks the scheduler can handle. If set to zero,
3137 default values are used. Affected file lib/silcclient/silcapi.h.
3139 * Fixed memory leaks in silc_client_close_connection. Affected
3140 file lib/silcclient/client.c.
3142 * Added silc_client_del_client_entry to client library to free
3143 all memory of given client entry. Affected file is
3144 lib/silcclient/idlist.[ch].
3146 * Added new functions silc_client_del_channel and
3147 silc_client_del_server to delete channel and server entries.
3148 Affected file lib/silcclient/[silcapi.h/idlist.c].
3150 * Removed silc_client_del_client_by_id from silcapi.h.
3152 * Fixed the INFO command to return the server's own info
3153 correctly when querying by Server ID. Affected file is
3156 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3158 * Removed the non-blocking settings in WIN32 code in the
3159 silc_sock_[read/write] and added SleepEx instead. Affected
3160 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3161 of input data is now checked with FIONREAD and ioctlsocket.
3163 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Call silc_schedule_task_del_by_context in the
3166 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3167 Affected file lib/silccore/silcprotocol.c.
3169 * Call silc_protocol_cancel for active protocols in the
3170 silc_server_close_connection if the funtion
3171 silc_server_free_sock_user_data has not been called.
3172 Affected file silcd/server.c.
3174 * Generic tasks cannot be deleted using the del_by_fd
3175 task deleting function since generic tasks does not match
3176 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3178 * Added a notion to SILCOPER help file that the SILCOPER works
3179 only on router server, not on normal server.
3181 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3183 * Added for WIN32 support for the new scheduler as well.
3184 Affected file lib/silcutil/win32/silcwin32schedule.c.
3186 * Fixed the SHA1 implementation to work on various platforms.
3188 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3191 API. It is part of the scheduler now. Everything else is
3192 as previously but some functions has changed their names.
3193 Checkout the lib/silcutil/silcschedule.h for the interface.
3194 Updated all applications to use the new interface. Affected
3195 files are lib/silcutil/silcschedule.[ch].
3197 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3199 * Found a bug in the SKE implementation. The HASH value,
3200 specified by the protocol, was not computed correctly. The
3201 public key of the responder was not added to the computation
3202 even though it is mandatory. Affected file lib/silcske/silcske.c.
3203 This unfortunately causes incompatibilities with older
3204 clients and servers.
3206 * Added WIN32 specific network init and uninit functions:
3207 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3208 the Winsock2. Affected file lib/silcutil/silcnet.h and
3209 lib/silcutil/win32/silcwin32net.c.
3211 * Set the socket always to nonblocking mode on WIN32 after
3212 reading data or writing data. Affected file is
3213 lib/silcutil/win32/silcwin32sockconn.c.
3215 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Fixed various compilation problems under WIN32. Affected
3218 files lib/silcutil/win32/silcwin32thread.c and
3219 lib/silcutil/win32/silcwin32schedule.c.
3221 * Removed all _internal.h #includes from public header
3222 files. Internal headers must never be included from
3225 Removed also the lib/silcske/payload_internal.h file.
3227 * All include files that may be needed (public and some others
3228 included by the public headers) by application developers are
3229 now copied to the ./includes directory. It does not copy any
3230 internal headers. Affected file Makefile.defines.pre and all
3231 Makefile.am's under lib/ and subdirs.
3233 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Do not change the ~/.silc directory's permissions automatically.
3236 Affected file irssi/src/silc/core/clientutil.c.
3238 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3240 * Do not cancel the protocol in silc_server_close_connection
3241 it might cause recursion. Now cancelled in the function
3242 silc_server_free_sock_user_data. Affected file silcd/server.c.
3244 * Fixed the silc_server_remove_clients_by_server to regenerate
3245 the channel keys correctly finally. Added also new function
3246 silc_server_remove_clients_channels to actually do it.
3247 Affected file silcd/server.c.
3249 * Fixed the silc_server_new_channel to not crash by giving
3250 wrong router to the new channel. Affected file is
3251 silcd/packet_receive.c.
3253 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3256 which is given as argument to the silc_client_alloc now.
3257 It can be used to configure the client and set various parameters
3258 that affect the function of the client.
3260 * The USERS command in server did not check whether the channel
3261 is private or secret. Affected file silcd/command.c.
3263 * Added new argument to the USERS command in protocol specification.
3264 The USERS command now can take the channel name as argument
3265 as well. Added support for this in client and server and
3266 updated the protocol specs.
3268 * Completed the GETKEY command in client. It can be now used
3269 to fetch also servers public key not only some clients.
3270 Affected files lib/silcclient/command[_reply].c.
3272 * Added silc_client_get_server to return server entry by the
3273 server name. Affected files lib/silcclient/silcapi.h and
3276 * Redefined the IDENTIFY command in protocol specification to be
3277 more generic. It now can be used to query information about
3278 any entity in the SILC Network, including clients, servers and
3279 channels. The query may be based either the entity's name
3280 or the ID. Added support for this in both client and server.
3282 Affected files silcd/command.c and lib/silcclient/command.c
3283 and command_reply.c.
3285 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3286 the _from_client and _from_server functions. Affected file
3289 * Added silc_client_get_channel_by_id_resolve to the file
3290 lib/silcclient/silcapi.h to resolve channel information by
3291 its ID. Added also silc_client_get_channel_by_id that
3292 does not resolve it from the server.
3294 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Added SilcServerEntry context into the client library
3297 to represent one server. The INFO command now allocates
3298 these to save the resolved server info. For now on the
3299 client library will also keep information about servers,
3300 connected and resolved with INFO.
3302 The INFO command now allocates the SilcServerEntry context
3303 and saves the server info there. The COMMAND_REPLY in
3304 the INFO now returns the parameters to application in
3305 same order as defined in the protocol specification.
3307 The entries are cached in the client->server_cache.
3309 * The INFO command is now issued after received the Client ID
3310 from the server. Affected file lib/silcclient/client.c.
3312 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3313 to the application as the mode changer might be server.
3314 It is guaranteed that NULL is not returned anymore to the
3315 application. Affected file lib/silcclient/client_notify.c.
3317 The ID Type is now also passed to the application so that
3318 it can check whether the returned entry is SilcClientEntry
3321 Added new function silc_client_get_server_by_id to return
3322 the server entry by ID. Affected files are the
3323 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3325 * Do not create the channel in the Irssi SILC Client when issuing
3326 the JOIN command but when received the sucessful JOIN command
3327 reply. Otherwise the channel might get created even though we
3328 could not join it. The Affected file is
3329 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3331 * Fixed a channel joining bug in router. The router must also
3332 check the channel modes, invite and ban lists etc. when serving
3333 the JOIN command sent by normal server. Affected file is
3334 silcd/command.c. The router now resolves the client's
3335 information from the server who sent the JOIN command if it
3336 does not know it, and processes the JOIN command only after
3339 * Changed the SilcCommandCb to take new argument; void *context2.
3340 Affected file lib/silccore/silccommand.h
3342 The second argument in the command callbacks in the server now
3343 includes the SilcServerCommandReplyContext if the command was
3344 called as pending command callback from the command reply.
3345 Otherwise it is NULL. When called as pending the status of the
3346 command reply will be checked and if it was erronous the
3347 error will be sent to the original sender of the command.
3348 This way the client always receives the error messages even
3349 though the server was actually the one who received the error
3350 when it resent the command to router, for example. Affected
3351 files silcd/command[_reply].[ch].
3353 * Fixed sending WHOWAS command's error message to client if
3354 the requested client could not be found. It was missing.
3357 * Changed the CMODE and CUMODE commands reply arguments in the
3358 protocol specification. The Channel ID is now sent in both
3359 of the commands to identify the channel. Implemented this
3360 new feature to the client and server. Affected files
3361 lib/silcclient/command_reply.c and silcd/command.c.
3363 * Made better checks for invite and ban lists in the JOIN
3364 command in server. Affected file silcd/command.c.
3366 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * The server now performs the incoming host IP/DNS lookup
3369 using the silc_socket_host_lookup and thus does not block
3370 the server anymore. Affected file silcd/server.c.
3372 * Completed the multi-thread support for SILC Scheduler in
3373 the lib/silcutil/silcschedule.c.
3375 * Fixed the configure.in.pre to detect the pthread correctly
3378 * Fixed a deadlock in silc_task_queue_wakeup in the file
3379 lib/silcutil/silctask.c.
3381 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Added new function silc_schedule_wakeup that is used in
3384 multi-threaded environment to wakeup the main thread's
3385 schduler. It needs to be used when a thread adds a new task
3386 or removes a task from task queues. After waking up, the
3387 scheduler will detect the task queue changes. If threads
3388 support is not compiled in this function has no effect.
3389 Implemented the wakeup mechanism to both Unix and WIN32
3390 systems. Affected files are lib/silcutil/silcschedule.[ch],
3391 lib/silcutil/unix/silcunixschedule.c and the
3392 lib/silcutil/win32/silcwin32schedule.c.
3394 * Added new function silc_task_queue_wakeup to wakeup the
3395 scheduler by the specified task queue. Affected file
3396 lib/silcutil/silctask.[ch].
3398 * The silc_socket_host_lookup_start now wakes up the scheduler
3399 after adding the timeout task. Affected file is
3400 lib/silcutil/silcsockconn.c.
3402 * The silc_socket_host_lookup is synchronous now if the threads
3403 support is not compiled in. However, the callback is still
3404 called asyncronously through the scheduler, anyway. Affected
3405 file lib/silcutil/silcsockconn.c.
3407 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Added new function silc_socket_host_lookup to perform
3410 asynchronous IP and FQDN lookups for the socket connection.
3411 Affected files lib/silcutil/silcsockconn.[ch].
3413 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3415 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3416 that may or may not compile the mutex support in.
3418 Changed the silc_mutex_alloc interface. It allocates the
3419 mutex now to the sent pointer and returns TRUE or FALSE.
3421 Affected file lib/silcutil/silcmutex.h.
3423 * Wrote the SILC Task Queue interface to support multi-threads.
3424 Affected file lib/silcutil/silctask.[ch].
3426 * Wrote the SILC Scheduler to support multi-threads. Affected
3427 file lib/silcutil/silcschedule.c.
3429 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3432 in lib/silcutil/win32/.
3434 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Defined SILC Mutex API and SILC Thread API and implemented
3437 them for Unix. Affected files are
3438 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3439 lib/silcutil/unix/silcunixmutex.c and
3440 lib/silcutil/unix/silcunixthread.c.
3442 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3444 * Fixed the silc_server_remove_clients_by_server's channel
3445 key re-generation. The hash table handling was incorrect
3446 and would not work with many channels. Affected file is
3449 * Fixed some memory leaks around the server code.
3451 * Rewrote the silc_server_get_users_on_channel to support IPv6
3452 based Client ID's. Affected file silcd/server.c.
3454 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3455 specification. However, a separate document must be written
3456 to define the detailed signing procedure and the payload
3457 associated with the flag. Defined the flag to the
3458 lib/silccore/silcchannel.h as well.
3460 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * Changed the dynamic tables to static size tables in the
3463 lib/silccrypt/silchmac.c.
3465 * Removed GCC dependencies from the code. A patch by cras.
3467 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3469 * Do not show the error "Error receiving packet bla bla"
3470 in server if it really was not an error (-2 means that reading
3471 is pending). Affected file silcd/server.c.
3473 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Fixed a possible crash in silc_server_remove_clients_by_server
3476 in silcd/server.c. Fixed there also some memory leaks.
3478 * Fixed the silc_idlist_replace_client_id. It could replace
3479 wrong key in the hash table. Affected file silcd/idlist.c.
3481 * Do not check whether there are global users on the channel
3482 if the channel->global_users is FALSE. Affected functions
3483 silc_server_remove_from_one_channel and
3484 silc_server_remove_from_channels in silcd/server.c. Also,
3485 do not check if the removed client is local as we can be
3486 sure that global client was not removed from the channel
3487 and checking for global users is not needed.
3489 * The silc_server_remove_clients_by_server now re-generates
3490 the channel keys correctly for those channels that had
3491 clients removed from them. Affected file silcd/server.c.
3493 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3495 * Found the reason of random crashes in the server. We weren't
3496 ignoring the SIGPIPE signal (which can be sent in write())
3497 and it crashed the server. Affected file silcd/silcd.c.
3499 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Assure that sock->user_data is not NULL in the function
3502 silc_server_packet_send in silcd/packet_send.c.
3504 * Disconnect the remote connection if it could not be added
3505 to any ID lists in the server. The affected file is
3508 * Check in silc_server_packet_send[_real/dest] that the
3509 socket is not disconnecting and ignore the data if it is.
3510 Affected file silcd/packet_send.c.
3512 * Define inline to __inline on native WIN32 compilation.
3513 Affected file includes/silcwin32.h.
3515 * Added some explicit type casts for inline code since MSVC
3516 require them. Affected files lib/silcutil/silcbuffer.h,
3517 lib/trq/silcdlist.h and lib/trq/silclist.h.
3519 * Print warning in log files from now on if the packet
3520 decryption fails. Affected file silcd/server.c.
3522 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Changed the `say' client operation's interface to accept
3525 new `type' argument to indicate the type of the message sent
3526 by the library. The application may filter the library's
3527 messages according the type. The affected file is the
3528 lib/silcclient/silcapi.h.
3530 * Added two new functions to lib/silcclient/silcapi.h:
3531 silc_client_del_client and silc_client_del_client_by_id.
3532 Affected file lib/silcclient/idlist.c.
3534 * Moved the clientincludes.h from includes/ to silc/ and
3535 serverincludes.h from includes/ to silcd/.
3537 * The modes for the CMODE and CUMODE are now passed as
3538 uint32 for application with COMMAND_REPLY. The affected
3539 file is lib/silcclient/command_reply.c.
3541 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * /WHOIS without arguments shows client's own information.
3544 Affected file lib/silcclient/command.c.
3546 * Changed PING to not accept any arguments. The specs
3547 says that client can ping only the connected server so
3548 requiring an argument is not needed. Affected file is
3549 lib/silcclient/command.c.
3551 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Fixed a fatal bug in private message sending and reception
3554 encryption and decryption when using private message keys.
3555 The implementation was incorrect and did not follow the
3556 specification. It causd that some of the message were
3557 lost since it did not use the sending and receiving keys
3558 as the protocol suggests. This has been fixed and will cause
3559 incompatibilities with older clients when sending private
3560 message encrypted with private message keys. Affected files
3561 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3562 and various other in Irssi SILC Client.
3564 Added `responder' boolean argument to the functions
3565 silc_client_add_private_message_key[_ske] to indicate when
3566 the key is added as responder or initiator of the key
3569 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Removed the silc_ske_check_version function and created
3572 a SilcSKECheckVersion callback. Added also a function
3573 silc_ske_set_callbacks that is now used to set all SKE
3574 callbacks. The callback functions are not given to
3575 the SKE functions anymore, but this function is used to
3578 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3580 * Added `silc_version' argument to the silc_client_alloc
3581 to define the version of the application for the library.
3582 The library will use the version string to compare it
3583 against the remote host's (usually a server) version
3584 string. Affected file lib/silcclient/silcapi.h
3586 * Added the KE protocol context to Key Agreement context
3587 in client library so that we can abort the SKE if it
3588 is in process when we get timeout. Affected file is
3589 lib/silcclient/client_keyagr.c.
3591 * Do not resolve the client ID forever if it returns in the
3592 first time that such client does not exist. This was done
3593 for example with private message. Affected file is
3594 lib/silcclient/client_prvmsg.c.
3596 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3598 * Do not add regex.h for WIN32. The affected file
3599 includes/silcincludes.h.
3601 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3602 not work yet 100%. It generates the DLL's automatically
3603 when compiling with --with-win32 under cygwin.
3605 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * lib/contrib/regex.c is not compiled on WIN32.
3609 * Added silc_net_get_socket_opt function to the
3610 lib/silcutil/silcnet.h.
3612 * Added includes/silcwin32.h for WIN32 specific includes
3615 * Do not use ptime structure or any of the posix process
3616 functions on WIN32 in lib/silccrypt/silrng.c.
3618 * Added silc_gettimeofday to provide generic function
3619 for struct timeval on all platforms. Added the function
3620 to lib/silcutil/silcutil.h.
3622 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3624 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3625 library as they clearly belong there. As a plus side we
3626 can make the actual socket connection routines platform
3629 Added also new generic function silc_socket_read and
3630 silc_socket_write (that used to be silc_packet_[read/write].
3631 The implementation of these are platform specific.
3633 * Added WIN32 specific routines of silc_socket_[read/write]
3634 to lib/silcutil/win32/silcwin32sockconn.c.
3636 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3638 * Added preliminary support for native WIN32 compilation under
3639 cygwin (using the -mno-cygwin option for GCC) to the
3640 ./configure.in.pre. The --with-win32 now prepares the
3641 compilation for native WIN32.
3643 * Rewrote the SILC Scheduler interface in the file
3644 lib/silcutil/silcschedule.h. The scheduler is now context
3645 based and does not have anymore any global static scheduler.
3646 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3647 and created lib/silcutil/win32 directory for WIN32 based
3650 * Added Unix specific network routines to the
3651 lib/silcutil/unix/silcunixnet.c and the old
3652 lib/silcutil/silcnet.c includes now only generic routines.
3654 Added WIN32 specific network routines to the
3655 lib/silcutil/win32/silcwin32net.c.
3657 * Added Unix specific utility functions from the
3658 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3660 * Added WIN32 SILC Scheduler to the file
3661 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3664 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3666 * Do not handle JOIN notify in the server if the target client
3667 is not registered (idata->registered == FALSE). The affected
3668 file is silcd/packet_receive.c.
3670 * Update the nickrec->founder in event_cumode in the Irssi SILC
3671 client. Affected file irssi/src/silc/core/silc-channels.c.
3673 * Fixed the CUMODE_CHANGE notify handling in the server when
3674 server and router are announcing their clients on channels.
3675 Now the mode changes are saved and notified correctly. The
3676 affected file is /silcd/packet_receive.c.
3678 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3679 They really did not replace the cache entry in the ID Cache.
3680 Now they do that. Affected file silcd/idlist.c.
3682 * Fixed the KICK notify handling in the Irssi SILC client to
3683 update the channel records so that the kicked client does not
3684 appear to be on the channel. The affected file is
3685 irssi/src/silc/core/silc-channels.c.
3687 * Always update the conn->current_channel when executing command
3688 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3690 * Fixed the KILL notify handling in Irssi SILC client to remove
3691 the killed client on all channels.
3693 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Fixed the silc_parse_command_line to remove extra spaces
3696 from the start and end of the arguments. Affected file is
3697 lib/silcutil/silcutil.c.
3699 * Cancel and free any active protocol in the function
3700 silc_server_close_connection. Affected file silcd/server.c.
3702 * Cancel and free any active protocol in the function
3703 silc_client_close_connction. Affected file is
3704 lib/silcclient/client.c.
3706 * Do not execute the KILL command for clients that are in
3707 history (ie. they are not in the network). Affected file is
3710 * Fixed KILL notify handling, client does not crash anymore.
3711 Affected file irssi/src/silc/core/silc-channels.c.
3713 * Reduced the default packet buffer size from 2048 to 1024 in
3714 lib/silccore/silcpacket.c.
3716 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3717 counter to the SKE context that is incresed when the SKE library
3718 performs async operation outside the library. If the outside
3719 process frees the SKE context and FREED status will be set
3720 and the library will detect after the sync operation that the
3721 libary is freed. The affected files are
3722 lib/silcske/silcske[_status].[ch].
3724 * Resolve the client entry information in the function
3725 silc_client_channel_message to assure that NULL pointer is not
3726 passed as client entry to the application. */
3728 * Fixed the task timeout calculation to assure that there is
3729 never negative timeouts. The affected file is
3730 lib/silcutil/silcschedule.c.
3732 * Fixed the channel user mode notification sending in server.
3733 It was sent point-to-point to the router (or to server by router)
3734 but it needs to be destined to a channel. The routines now
3735 supports sending the channel user mode notifys to the channels
3736 when announcing clients and channels. Affected files are
3737 silcd/server.c and silcd/packet_receive.c.
3739 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3740 It did not actually replace the old channel entry in the cache.
3741 Affected file lib/silcclient/client_notify.c.
3743 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Fixed a possible crash in silc_packet_send_prepare. It now
3746 assures always that there is enough space in the buffer and
3747 at the tail area of the buffer (for MAC).
3749 Fixed the inbound buffer reallocation in silc_packet_read.
3750 It was old code and did not handle the reallocation correctly.
3753 The affected file is lib/silccore/silcpacket.c.
3755 * Fixed buffer overflow in silc_parse_nickname in the file
3756 lib/silcutil/silcutil.c.
3758 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * make install generates new server keys only if there is not
3763 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3766 Added check that if the NOREPLY is set then we will not send
3767 the away message. This avoids infinite loop of away messages
3768 if both clients are away. The affected file is
3769 lib/silcclient/client_prvmsg.c.
3771 * Fixed client crash if /NICK was given without arguments.
3772 Affected file lib/silcclient/command.c.
3774 * Server does not send the invite list in INVITE command back
3775 to the client if the list was not altered. Added this notion
3776 to the protocol spec as well. Affected file silcd/command.c.
3778 Fixed possible crash in INVITE command by checking the
3779 value of silc_server_get_client_route command.
3781 * Fixed the INVITE notify type handling. The arguments are now
3782 taken in correct order and client does not crash. The affected
3783 file is irssi/src/silc/core/silc-channels.c.
3785 Removed the "Inviting xxx to channel" message from the
3786 client library away and let the application handle it.
3787 Affected file lib/silcclient/command.c. Added that message
3788 to Irssi SILC client's message formats.
3790 * Fixed CMODE command crash in client. It now checks the
3791 amount of arguments correctly and does not crash. The affected
3792 file is lib/silcclient/command.c.
3794 * Do not create new channel automatically in silc_channels_join
3795 but check whether the channel by that name already exists.
3796 Affected file irssi/silc/core/silc-channels.c.
3798 * Do not send the SERVER_SIGNOFF to router if the disconnected
3799 entity was the router. Affected file silcd/server.c.
3801 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3802 SILC client as it was missing from there.
3804 Added the handling of the KICK notify to the Irssi SILC client
3805 as it was missing. Added "you have been kicked" message to
3806 Irssi SILC client's message modules formats.
3808 Added the handing of the KILL notify to the Irssi SILC client
3809 as it was missing. Added the kill message module formats
3812 The affected file is irssi/src/silc/core/silc-channels.c.
3814 * The router did not save the channel mode the server announced.
3815 Affected file silcd/packet_receive.c.
3817 * Fixed a possible crash in INFO command in server. If the
3818 server did not provide the server info it crashed. Affected
3819 file silcd/command.c.
3821 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Fixed the GETKEY command in the server to check also the
3824 global list. Otherwise the GETKEY would not work correctly
3825 in normal SILC server. Affected file silcd/command.c.
3827 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Fixed GETKEY crash, it crashed if the command did not succseed.
3831 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3834 is now real and not just an macro interface to GMP.
3836 Removed the entire GMP from the source tree and imported new
3837 NSS MPI library instead. Reason for removing GMP is that it is
3838 extremely large and compiles extremely slow. The NSS MPI
3839 is only a few files and compiles in less than 10 seconds.
3840 The speed is also about the same as GMP. The MPI is imported
3841 to lib/silcmath/mpi.
3843 If the system has GMP installed we will still use the GMP.
3844 If it is not then the NSS MPI will be compiled.
3846 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Merged a long nickname (127 characters long) crash bugfix from
3849 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3851 * Merged a freed memory reference bugfix from Irssi CVS tree.
3852 Affected file irssi/src/core/commands.c.
3854 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Added the server's public key sving and verification to the
3857 server when performing the SKE. This was missing and the
3858 remote server's (or router's) public key was accepted without
3859 checking whether we have it previously or trust it at all.
3860 Affected file silcd/protocol.c.
3862 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Check in the silc_server_timeout_remote if protocol is active
3865 and make sure that the protocol's final callback is called so
3866 that all memory if freed. Affected file silcd/server.c.
3868 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * silc_server_whois_send_reply crashed the server if the nickname
3871 was 127 characters long. Affected file silcd/command.c.
3873 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Added sanity check to the silc_server_new_client. If the hostname
3876 is provided inside username then check that the provided hostname
3877 really is the same as the resolved one. If the hostname was not
3878 resolved then check it from the public key. Affected file is
3879 silcd/packet_receive.c.
3881 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3882 if the server disconnected us and the connection is not valid
3883 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3885 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3886 the library to the lib/silcutil/silcutil.[ch].
3888 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Close log file after open. Affected file
3891 lib/silcutil/silclog.c.
3893 * Check whether sock == NULL in silc_client_send_packet and return
3894 if it is. Affected file lib/silcclient/silcclient.c.
3896 * Check rec->entry == NULL in the Irssi SILC Client before
3897 sending the channel message. Affecte file is
3898 irssi/src/silc/core/silc-servers.c.
3900 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Merged a splitted window bugfix from Irssi CVS tree. The
3903 affected file is irssi/src/fe-text/textbuffer-view.c.
3905 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3906 It did not print nickname.
3908 * Improved the distributions system a bit.
3910 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3913 irssi/src/fe-text/gui-window.c.
3915 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3916 to in-active server. The affected file is
3917 irssi/src/silc/core/client_ops.c.
3919 * Resolve the client in USERS command reply if the entry does
3920 not have username resolved. The affected file is
3921 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3922 command to WHOIS command to really resolve stuff. The USERS
3923 is not used any more in any critical section so WHOIS can
3924 be used even though it might be slower than IDENTIFY.
3926 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3929 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Changed the protocol API a bit more consistent in the
3932 lib/silccore/silcprotocol.[ch].
3934 * Changed the following headers to ROBODoc format:
3936 lib/silccore/silcpayload.h
3937 lib/silccore/silcprotocol.h
3938 lib/silccore/silcsockconn.h
3940 All core library headers are now formatted.
3942 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Fixed a bug in Irssi SILC client; do not show that you are
3945 server/router operator if you really are not. Affected file is
3946 irssi/src/silc/core/client_ops.c.
3948 * Renamed silc_command_free_payload to silc_command_payload_free.
3949 Affected file lib/silccore/silccommand.h
3951 * Added silcmath.h to include the prototoypes of various routines
3952 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3955 * Changed the following headers to ROBODoc format:
3957 lib/silccore/silcchannel.h
3958 lib/silccore/silccommand.h
3959 lib/silccore/silcid.h
3960 lib/silccore/silcidcache.h
3961 lib/silccore/silcmode.h
3962 lib/silccore/silcnotify.h
3963 lib/silccore/silcpacket.h
3964 lib/silcmath/silcmath.h
3966 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Added checking to the server code not to start the server if
3969 ciphers and stuff are not configured properly. Affected files
3970 silcd/serverconfig.[h] and silcd/server.c.
3972 * Changed the layout of the header files of the public interfaces
3973 in the SILC libraries. The new layout supports ROBODoc
3974 documentation tool (and some others) so that it is easy to create
3975 a library reference manual. All the other headers and source
3976 code must still follow the CodingStyle document. Also source
3977 code must not include these ROBODoc stuffs, only the headers.
3978 Furthermore, all public interface headers must now be named
3979 by using `silc' prefix, example: silcapi.h, silccipher.h.
3980 Some files were renamed due to this. All the other headers
3981 must not be used as public interfaces. I will update the
3982 CodingStyle document later. Changed following headers, so far:
3984 lib/silcclient/silcapi.h
3985 lib/silccore/silcauth.h
3986 lib/silccore/silcprivate.h
3987 lib/silccrypt/silcdh.h
3989 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Removed silc_client_packet_send_flush from the client library
3994 as it is not needed. Affected file lib/silcclient/client.[ch].
3996 * Added printing of message of unresolved authentication method
3997 to the Irssi SILC client. Added it to the module formats.
3998 Removed the same message from the client library.
4000 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Added new distribution feature, DISTLABEL. Every distribution
4003 can define own preprocessor label that can be used in the
4004 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4005 file distributions, acconfig.h.pre and prepare.
4007 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Added Makefile.defines_int to include the actual definitions
4010 for Makefile.defines.in. Tested the new distribution system,
4011 created distributions and tested installation.
4013 * Added AWAY message printing to the Irssi SILC client. Added
4014 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4016 * Added SCONNECT command to call the SILC's CONNECT command.
4017 Cannot use CONNECT directly since Irssi uses that internally.
4018 Affected file irssi/src/silc/core/silc-servers.c.
4020 Added ACTION local command. It is same as ME command but takes
4021 the channel as mandatory argument.
4023 Rewrote some of the Irssi's help files to suite for SILC
4026 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Added Makefile.defines[.in] that should for now on be included
4029 in all Makefile.am file in the source tree. That file includes
4030 all common compilation definitions for SILC source tree.
4032 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Minor changes to the ./prepare script to change the package
4035 name according the distribution name to the configure.in.
4037 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Created new distribution system. Added file `distributions'
4040 that defines all the distributions that can be created out of
4041 the SILC source tree. The ./prepare script now reads that
4042 file to determine how to prepare the distributions. The
4043 first argument to the ./prepare is the name of the distribution
4044 and second is the version of the distribution. If given
4045 without arguments it creates the default (toolkit) distribution
4046 with the default version (defined in ./prepare).
4048 All Makefile.am files that are subject to the distributions
4049 are now named as Makefile.am.pre. These are ./Makefile.am
4050 and lib/Makefile.am. Others may be changed later.
4052 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Added invite list, ban list, some key management and connection
4055 error message printing to module formats in the Irssi SILC client.
4057 * Added new silc_client_set_away_message to set the away message
4058 that is back to the person who sent private message. The
4059 affected file lib/silcclient/silcapi.h and the
4060 lib/silcclient/client_prvmsg.c.
4062 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Fixed the private message sending in the Irssi SILC client,
4065 added local command KEY to the Irssi SILC client.
4067 Added key management and key agreement message formats to the
4068 irssi/src/fe-common/silc/module-formats.[ch].
4070 Added USERS (alias WHO) printing, server/router operator
4071 indication and LIST command printing to the module formats.
4073 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Fixed channel joining notify handling, cumode notify handling
4076 from Irssi SILC client.
4078 * Added SILC specific module-formats to the Irssi SILC client so
4079 that SILC specific message hilighting, colors etc is possible.
4080 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4082 Added channel mode, channel user mode, actions, notices,
4083 whois and whowas printing to the the module-formats.c.
4085 * Fixed a bug in channel deletion in the server. The channel
4086 is not left to the cache even if the channel founder auth mode
4087 is set when there are no users anymore on the channel. Affected
4088 file silcd/server.c.
4090 * The silc_net_localhost now resolves the entire hostname including
4091 the domain name. Affected file lib/silcutil/silcnet.c.
4093 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * Changed the ask_passphrase client operation to be ascynchronous.
4096 It has now a completion callback and a context that the
4097 application must call after it has got the passphrase from
4098 the user. Affected files lib/silcclient/silcapi.h,
4099 lib/silcclient/protocol.c, lib/silcclient/command.c and
4102 Added SilcAskPassphrase callback that the application calls
4103 to deliver the passphrase to the library.
4105 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4106 The public key verification and especially a certificate
4107 verification is asynchronous procedure.
4109 Added new SILC_SKE_STATUS_PENDING status to indicate the
4110 request is pending and a callback will be called to finalize
4113 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4114 indicate that remote end did not send its public key (or
4115 certificate), even though we require it. Added check for this
4116 condition in the SKE. This was a security bug, now fixed.
4118 Defined new SilcSKEVerifyCbCompletion callback that is called
4119 when the verification process is completed.
4121 The affected files lib/silcske/silcske_status.h and
4122 lib/silcske/silcske.[ch].
4124 * Changed the verify_public_key client operation to be async
4125 as well. Defined SilcVerifyPublicKey callback that is used to
4126 indicate the success of the public key verification process.
4128 Changed the server and client to use the new async client
4131 * Changed the Irssi SILC client's internal scheduler to be called
4132 twice as many times as it used to be. As a result the client
4133 should be a bit faster now. Affected file is
4134 irssi/src/silc/core/silc-core.c.
4136 * Added support to Irssi SILC client of asynchronous public key
4137 verification and passphrase inquiry. Affected file is
4138 irssi/src/silc/core/silc-core.c.
4140 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Do not say "You have left channel %s" in client library.
4143 Moved it to the application. Affected files are
4144 lib/silcclient/command.c and silc/client_ops.c.
4146 * Fixed silc_client_get_clients. Command context was not
4147 duplicated and was freed memory in the callback. Affected
4148 file lib/silcclient/idlist.c.
4150 * Do not say "you are now talking..." on JOIN command in the
4151 client library. The appliation must handle it.
4153 * Do not say ".. changed topic to" in command reply in the
4154 client libary. The application must handle it.
4156 * Fixed TOPIC command sending in the client library.
4158 * Fixed a memory leak in silc_client_command_free in the file
4159 lib/silcclient/command.c.
4161 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Imported a modified version of Irssi client to the source tree.
4164 The Irssi will be used to create a new client called
4165 Irssi SILC. Imported to irssi/.
4167 Added silc_core_init_finish function to the Irssi. Affected
4168 file irssi/configure.in.
4170 A lot changes in the Makefile.ams around the irssi tree.
4172 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Do not rehash if the new size is same as the old size of the
4175 hash table, in the silc_hash_table_rehash*. The affected file
4176 lib/silcutil/silchashtable.c.
4178 * Replaced hash_table_del_by_context calls from the server
4179 (when channel->user_list and client->channels) to the
4180 hash_table_del as it is sufficient and faster.
4182 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Added silc_hash_table_list, silc_hash_table_get and the
4185 SilcHashTableList structure to provide an alternative way to
4186 traverse the hash table. The affected files are
4187 lib/silcutil/silchashtable.[ch].
4189 * Changed the server's idlist routines to use the hash table
4190 routines to optimize the code.
4192 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Replaced the client entry's `channel' list and channel entry's
4195 `user_list' list to hash tables for optimized lookup. Changed
4196 the code to use the hash table interface around the code.
4197 Affected file lib/silcd/idlist.[ch].
4199 * Added `auto_rehash' boolean argument to the function
4200 silc_hash_table_alloc to indicate whether the hash table should
4201 auto-rehash when it thinks is appropriate time. It will
4202 increase the hash table size if the there is twice as much
4203 entries in the table than the size of the table, and will
4204 decrease the size if there are twice as less entries than
4205 the size of the table.
4207 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4211 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * silc_idcache_purge_by_context deletes the entry now by context
4214 as it is supposed to do. Affected file lib/silccore/idcache.c.
4216 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4217 client is not anymore valid (WHOWAS givens the info) and not
4218 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4220 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Removed the `data' and `data_len' arguments from the ID Cache
4223 interfaces and added `name' argument. ID Cache does not handle
4224 anymore the binary data only a names associated with given ID.
4226 * When hashing a Client ID with silc_hash_id the entire ID is
4227 not hashed anymore, instead only the hash of the Client ID is
4228 hashed. This way we can access the Client ID from the cache
4229 with Client ID but with the hash of the ID (which is a hash of
4230 the nickname) as well without any difference in performance.
4232 Added also silc_idcache_find_by_id_one_ext to do one on one
4233 searching when we have the actual ID. Added also function
4234 silc_hash_client_id_compare. The affected files are
4235 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4237 * When hashing the name associated with a ID it is always done
4238 in lowercase. This way we can access the cache without worrying
4239 about case-sensitivity, even though, for example nicknames are
4242 * Fixed a bug in server with channel message sending. It put
4243 wrong ID type as destination ID. The affected file
4244 silcd/packet_send.c.
4246 * silc_idcache_del_by_context now deletes from all hash tables
4247 by context. Affected file lib/silccore/idcache.c.
4249 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Changed the client library to use the new ID Cache interface.
4252 Changes around the source tree.
4254 * Added silc_hash_table_rehash_ext to rehash with specific
4255 hash function. Affected file lib/silcutil/silchashtable.[ch].
4257 * Added silc_hash_string_compare to compare two strings in the
4258 hash table. Affected file lib/silcutil/silcutil.[ch].
4260 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Added new function silc_idcache_del_by_context into the
4263 lib/silccore/idcache.[ch].
4265 * Changed the server's ID list routines to use the new ID Cache
4266 interface. Changes around the source tree.
4268 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Added silc_hash_table_del[_by_context]_ext functions in to the
4271 lib/silcutil/silchashtable.[ch].
4273 Removed silc_hash_table_find_all* routines and added new
4274 silc_hash_table_find_foreach to replace them.
4276 Added silc_hash_table_replace_ext function as extended
4277 replacing function. Separated the simple hash table interface
4278 from the extended hash table interface in the file
4279 lib/silcutil/silchashtable.h.
4281 * Fixed minor bugs and changed it to use some of the new
4282 hash table functions in lib/silccore/idcache.c
4284 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Added new function silc_hash_table_find_all to return all keys
4287 in the hash table by the specified key. As the hash table is
4288 collision resistant it also makes it possible to have several
4289 duplicate keys in the hash table. This function may be used to
4290 find all of the keys from the hash.
4292 Added user_context arguments to the SilcHashFunction,
4293 SilcHashCompare and SilcHashDestructor to deliver user specified
4296 Added new fuctions silc_hash_table_find[_all]_ext to do
4297 extended lookup with specified hash and compare functions and
4298 specified user contexts.
4300 Added new function silc_hash_table_add_ext to add the key
4301 with specified hash function and user context.
4303 Added new function silc_hash_table_foreach to traverse all
4304 entrys in the hash table. Added SilcHashForeach callback
4307 Added new function silc_hash_table_del_by_context to delete
4308 the entry only if the context associated with the key matches.
4310 Affected files are lib/silcutil/silchashtable.[ch].
4312 * Removed silc_hash_[server/client/channel]_id and added just
4313 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4314 silc_hash_id_compare to compare two ID's using as the hash table
4315 comparison function. Added also silc_hash_data to hash
4316 binary data and silc_hash_data_compare to compare it.
4318 * Removed silc_idlist_find_client_by_hash as it is not needed
4319 anymore. Affected file silcd/idlist.[ch].
4321 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4322 to use internally the SilcHashTable. The new ID Cache is a lot
4323 faster than the old one. Some of the ID Cache interface was also
4324 rewritten and obsolete and stupid functions were removed.
4326 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Added entry_count field to the SilcHashTable to keep the number
4329 of the entries in the table. Implemented the function
4330 silc_hash_table_rehash. Added new function
4331 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4333 Fixed a minor bug in silc_hash_table_free.
4335 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4336 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4337 into the lib/silcutil/silcutil.[ch].
4339 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Implemented a collision resistant hash table into the
4342 lib/silcutil/silchashtable[ch]. See the header and the source
4343 for the SilcHashTable API.
4345 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Merged dotconf version 1.0.2 into lib/dotconf.
4349 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Do not compile anything in lib/silcsim/* if the SIM support
4352 is not enabled. The tree should now compile without problems
4355 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Compiled the SILC under cygwin. Compiled and tested briefly
4358 without problems. More tests needed. The SIMs didn't compile
4361 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4363 * Fixed possible crash in silc_get_username in the
4364 lib/silcutil/silcutil.c.
4366 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Fixed a va_arg in silc/client_ops.c.
4370 * Oops, RC5 routines were named AES and caused some problems
4371 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4373 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Added new SilcIDIP structure into the lib/silccore/id.h and
4376 replaced the old `ip' fields from all SILC ID's to that type.
4377 This is a step towards IPv6 support.
4379 The silc_id_get_len takes now the ID as an extra argument.
4380 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4381 both IPv4 and IPv6 based ID's.
4383 The affected files are lib/silccore/id.[ch] and other files
4384 around the tree using these routines.
4386 * Removed the ID length arguments in server from various
4387 silc_server_send_notify_* routines -> they are not needed
4390 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Fixed memory leak in silc_encode_pem_file in the file
4393 lib/silcutil/silcutil.c.
4395 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Check minor version as well in the SKE. Affected files are
4398 silcd/protocol.c and lib/silcclient/protocol.c.
4400 * Added --identifier option to the server so that an identifier
4401 can be when creating the public key for the server. Affected
4402 file is silcd/silcd.c.
4404 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4405 lib/silccrypt/silcpkcs.c.
4407 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Register default ciphers and stuff when using -C option with
4410 the server. Affected file sildc/silcd.c.
4412 * Put back the servers public key filename format, it is better
4413 than the new one. For now, the client keys are saved with the
4414 new filename format. The affected file silc/client_ops.c.
4416 * Implemented the Cipher API for the rest of the ciphers that
4417 did not implement it or implemented it the wrong way.
4419 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Register default ciphers and stuff when using the -S option
4422 in the client. Affected file silc/silc.c. Same also when
4423 creating new key pair with -C option.
4425 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Fixed the silc_verify_public_key client operation function to
4428 save the public keys differently. The fingerprint is now
4429 used as filename and not the hostname. This way also the
4430 client keys are saved uniquely and not with hostnames. The
4431 affected file is silc/client_ops.c.
4433 * Trimmed the silc_hash_fingerprint function to remove extra
4434 whitespaces from the end of the fingerprint. The affected
4435 file is lib/silccrypt/silchash.c.
4439 * Added silc_cipher_register_default function to register all
4440 default ciphers. It can be used when configuration files
4441 does not exist and the application does not want any specific
4442 ciphers in any specific order.
4444 The SilcDList is now used as silc_cipher_list dynamically
4445 allocated cipher list. Removed the static list all together
4446 and now all ciphers must be allocated to the dynamic list.
4447 The silc_cipher_alloc routine was changed to check only the
4450 All silc_cipher_* routines that used to return int returns
4453 The affected files lib/silccrypt/silccrypt.[ch].
4455 * The same thing was done to silc_hash_* as for silc_cipher_*
4456 routines. Affected files lib/silccrypt/silchash.[ch].
4458 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4459 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4460 Added also silc_pkcs_[un]register[_default] functions.
4461 Removed the data_context from the PKCS API.
4463 * Added silc_hmac_register_default function to register default
4464 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4465 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4466 to unregister all hmacs at once.
4468 * Register the default ciphers, hash functions, PKCSs and HMACs
4469 if client's configuration file does not exist. The affected
4472 * The client did not load the hash functions from the SIM
4473 modules at all. Added support for this. Affected file is
4474 silc/clientconfig.c.
4476 * When decoding public key with silc_pkcs_public_key_decode, check
4477 the supported algorithm only if PKCS are registered. Affected
4478 file lib/silccrypt/silcpkcs.c. The same was done with the
4479 silc_pkcs_private_key_decode.
4481 * Fixed the SILC List routines to keep the list always in order.
4482 It used to change the list's order when traversing the list but
4483 not it preserves the order. Affected file lib/trq/silclist.h.
4485 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Added the client library to use the SilcSocketConnection's
4488 reference counter (by silc_socket_dup) to prevent the bug that
4489 the socket object may be freed underneath async operation.
4491 * The name resolv library checking fixes in the configure.in.pre.
4494 * Created new version of the protocol drafts for future
4495 development. The -03 drafts are the ones that will be changed
4496 in the trunk now and the -02 will remain as they are.
4498 * Send list of CUMODE notifys to the router when announcing
4499 the channel users to the router. Affected file silcd/server.c.
4500 If the router receiving channel founder CUMODE for a channel
4501 that already has channel founder it will send CUMODE notify
4502 to the sender to remove the channel founder rights from the
4503 announced client. Affected file silcd/packet_receive.c.
4505 * The CUMODE notify may now use Server ID as well as the entity
4506 who changes the mode. Updated protocool specs.
4508 * Updated INSTALL and README files.
4510 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * New web pages in the http://silc.pspt.fi. The pages was
4517 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Implemented the [DenyConnectin] config section in the server.
4520 Added silc_server_config_denied_conn to check whether incoming
4521 connection is denied. Affected file silcd/serverconfig.[ch].
4523 * Do not check the ports when checking the incoming configuration
4524 data if the port is 0, meaning any. Affected file is
4525 silcd/serverconfig.c.
4527 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Fixed buffer overflow in silc_string_compare in the file
4530 lib/silcutil/silcutil.c.
4532 * Fixed double free in silc_server_command_leave in the file
4535 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Fixed the version checking in the server. Affected file is
4540 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Fixed the configuration data fetching when accepting new
4543 connections in the server. Affected file silcd/server.c.
4545 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Added `sender_entry' argument to the function
4548 silc_server_packet_relay_to_channel so that we can check
4549 whether some destination actually belongs to the same route
4550 the sender belongs (ie, we must not resend the packet to the
4551 sender). Affected file silcd/packet_send.[ch].
4553 * Added `servername' field to the SilcClientEntry in the server
4554 to hold the name of the server where client is from. Affected
4555 file is silcd/idlist.h.
4557 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Moved the channel message encrypting in the router betwen
4560 router connections from silc_server_channel_message to the
4561 silc_server_packet_relay_to_channel since we want to check
4562 whether we have anybody channel before encrypting anything.
4563 Affected files silcd/packet_[receive/send].c.
4565 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Fixed the [AdminConnection] server config section to support
4568 multiple entries. Affected file silcd/serverconfig.c.
4570 * Added support into the server to check the validity of the
4571 incoming connection before executing any KE or authentication
4574 * The connection configuration is now saved to the KE and
4575 connection auth protocol contexts and not fetched anymore in
4576 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4578 * The local hosts listenning address and port is also resolved
4579 now when starting the server. We want to have the socket object
4580 to include the real address and port for the listener. Added
4581 new function silc_net_check_local_by_sock into the files
4582 lib/silcutil/silcnet.[ch].
4584 * Fixed a broadcast bug in server -> do not broadcast if we
4587 * Fixed a routing bug. Do not route broadcast packets ever.
4588 Broadcast packets must be processed always and not routed since
4589 they may be destined to some other host than yourself and thus
4590 would get routed without no good reason. Affected file is
4593 * Added function silc_server_config_is_primary_route to check
4594 whether primary router connection has been configured (a router
4595 configuration that we are initiating). If there is not, we
4596 will assume that there is only two routers in the SILC network
4597 and we will use the incoming router connection as our primary
4598 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4600 * Changed the order of the broadcasting. Broadcast _after_ the
4601 packet has been processed not before. Affected file is
4604 * Fixed a [ClientConnection] parsing bug. The port was never
4605 parsed correctly thus resulting to port 0. Affected file
4606 silcd/serverconfig.c.
4608 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4609 argument and did not set the broadcast packet flag. Affected
4610 file silcd/packet_send.c. Fixed same bug in the function
4611 silc_server_send_notify as well.
4613 * If we receive NEW_ID packet for our own ID in the server, ignore
4616 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Removed the nickname from the Private Message Payload.
4621 Updated the code and the protocol specs.
4623 * Updated protocol specs for submitting to the IETF.
4625 * Tweaked the Random Number Generator a bit. Affected file
4626 lib/silccrypt/silcrng.c. Exported a new function
4627 silc_rng_[global]_add_noise which can be used to add more
4630 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Do not parse packets with different timeout when protocol
4633 is active -> may cause problem with rekey. Affected file
4636 * When server receives signoff notify it must not create
4637 new channel key if the client is on any channels since the
4638 sender of the signoff notify will create it.
4640 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Added printing of error messages during SKE protocol from the
4643 failure packet sent by server during SKE. Affected file
4646 * Removed the client's failure_callback handling with timeout
4647 and handle it immediately when received.
4649 * The SKE library returned wrong type in SUCCESS and FAILURE
4650 packets. They must be 32 bit MSB not 16 bit MSB.
4652 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Ok, rewrote the logic of the re-key and now it seems to work.
4655 I tested it on high traffic with frequent re-keys without
4656 problems. Added hmac_receive (and renamed hmac to hmac_send)
4657 in SilcClientConnection in lib/silcclient/client.h and
4658 in SilcIDListData in silcd/idlist.h. Also, removed the
4659 SilcPacketParserContext's cipher and hmac fields as they are
4660 not needed anymore and actually caused some problems when
4661 the ciphers and hmac's changed underneath the packet parser.
4663 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * If re-key protocol is active then process the incoming packets
4666 synchronously since we must assure that icoming packets encrypted
4667 with the old key is processed before the new keys is set to
4668 use. This is true other packets than for REKEY packets.
4669 Affected file silcd/server.c. The same was done to client library
4670 as well, affected file lib/silcclient/client.c.
4672 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Fixed bug in client and server to accept the force send if
4675 the packet is send from silc_[server/client]_packet_process
4676 function. Otherwise the packets are never delivered, oops.
4678 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Disable force sending of packets when REKEY protocol is active.
4681 We must assure that no packet is sent directly when rekey is
4682 performed. All packets must be sent through packet queue.
4683 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4684 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4685 function is silc_[server/client]_packet_send_real to check
4688 * Replaced the SIM paths from example config files to
4689 /usr/local/modules. Also, make install creates now
4690 /usr/local/silc/logs directory to hold all the SILC server
4693 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Made the configure.in.pre work on Solaris. Patch by salo.
4697 * Made all ciphers compatible with non-x86 machines. Defined
4698 CBC mode macros into lib/silccrypt/ciphers_def.h.
4700 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed the make install.
4704 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * When MAC computation fails the silc_packet_decrypt returned 0
4707 even though it was supposed to return -1. Fixed this. The
4708 affected file is lib/silccore/silcpacket.c.
4710 * Do not replace the config files in /etc/silc (in make install)
4711 if they already exist. Affected file ./Makefile.am.
4713 * Do not send re-key packets immediately but through packet queue.
4714 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4716 * Changed silc_net_check_host_by_sock to return FALSE if the
4717 IP/DNS could not be resolved. Though, it returns the IP address
4718 now even if it could not resolve it (but returns also FALSE).
4719 Affected file lib/silcutil/silcnet.[ch].
4721 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Added silc_pkcs_decode_identifier to decode the public key's
4724 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4725 Added also silc_pkcs_free_identifier. Added also new context
4726 SilcPublicKeyIdentifier.
4728 * Added -S option to the silc client. It is used to dump the
4729 contents of the specified public key file.
4731 * Changed the PKCS api to return the public key length when
4732 setting the public key.
4734 * Fixed a fatal bug in the public and private key file loading.
4735 Affected file lib/silccrypt/silcpkcs.c.
4737 * Execute the packet parsing for client with zero (0) timeout
4738 if the protocol is active. Affected file silcd/server.c.
4740 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Made the key generation options to the silcd program. Added
4743 -C option, equivalent to client's option.
4745 * Added new [ServerKeys] config section to the server. It
4746 configures the server's public and private key.
4748 * Defined generic Public Key Payload into the protocol
4749 specification to send specific type of public keys and
4752 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4753 public key or certificate.
4755 * Implemented the GETKEY command to the server and to the
4756 client library and on user interface.
4758 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Made preliminary `make install' work.
4762 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Added SilcServerRekey context into silcd/idlist.h.
4766 * Added the PFS support as defined in the specification to the
4767 SKE protocol. Affected files lib/silcske/*.c.
4769 * Added `ske_group' field to the SilcServerRekey context to hold
4770 the number of the SKE group that is used with PFS in re-key.
4771 Affected file silcd/idlist.h.
4773 * Added PFS re-key support to the server. Affected file is
4776 * Added silc_protocol_cancel to cancel execution of the next
4777 state of the protocol. Affected file is
4778 lib/silccore/silcprotocol.[ch].
4780 * Added the re-key support with and without PFS to the client
4781 library. Re-key is performed once in an hour, by default.
4783 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4784 Added silc_client_rekey_callback and silc_client_rekey_final.
4785 Affected files are lib/silcclient/protocol.[ch] and
4786 lib/silcclient/client.[ch].
4788 * Removed the `hmac_key' and `hmac_key_len' fields from the
4789 SilcClientConnection structure; not needed. Affected file is
4790 lib/silcclient/client.h.
4794 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Do not ask whether user wants to use the negotiated private key
4797 for private messages, just use it. Affected file is
4798 silc/local_command.c.
4800 * Added `send_enc_key' and `enc_key_len' fields to the
4801 SilcIDListData structure since they are needed in the re-key
4802 phase. Affected file is silcd/idlist.[ch].
4804 * Implemented the simple re-key protocol into the server.
4805 Affected files silcd/server.c and silcd/protocol.[ch]. The
4806 re-key will be performed once in an hour, by default.
4808 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4809 Added silc_server_rekey, silc_server_rekey_callback and
4810 silc_server_rekey_final.
4812 * Removed Tunneled flag from the protocol. Updated the code
4813 and the specifications.
4815 * Adde `pfs' field to the SilcIDListData to indicate whether
4816 the PFS is to be performed in the re-key. Affected file is
4819 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4822 int64 of at least the xintXX size. If void * is less that 4
4823 bytes uint32 * will be used. Defined bool as boolean.
4825 * Changed _ALL_ unsigned long and unsigned int to uint32,
4826 unsgined short to uint16 in the source tree.
4828 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4829 not handle clients that has entry->data.registered == FALSE.
4830 They are not in the network anymore. Affected file is
4833 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Implemented the sending of the SERVER_SIGNOFF notify in the
4836 server. Affected file is silcd/server.c.
4838 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4839 Added also silc_notify_payload_encode_args into the
4840 lib/silccore/silcnotify.[ch].
4842 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4843 Affected file silcd/packet_receive.c.
4845 * Implemented the SERVER_SIGNOFF notify handling in the client
4846 library. Affected file lib/silcclient/client_notify.c. Also,
4847 implemnted the printing of the SERVER_SIGNOFF info to the
4848 application. Affected file silc/client_ops.c.
4850 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4851 if the deleting was successful. Affected file silcd/idlist.[ch].
4853 * Added support for public key authentication in the connection
4854 authentication protocol in the client library. Affected file
4855 lib/silcclient/protocol.c.
4857 * Changed the server's silc_idlist_get_clients_by_* interface
4858 to support already allocated array so that new entries may be
4859 added to pre-allocated array. Affected file silcd/idlist.[ch].
4860 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4861 and command replies.
4863 * All command reply functions in the server now calls the
4864 pending command callback even if error occured. This way the
4865 error will be delivered to the client as well. Affected files
4866 silcd/command.c and silcd/command_reply.c.
4868 * Fixed INFO command to return local server's info if no server
4869 was provided. Affected file lib/silcclient/command.c.
4871 * Removed RESTART command for good. Updated the code and the
4874 * Rewrote parts of the task system. It is a bit simpler now.
4875 Removed unsued task priorities. The affected files are
4876 lib/silcutil/silctask.[ch].
4878 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Moved the USERS printing from the library to the application.
4881 Affected files lib/silcclient/command.c and silc/client_ops.c.
4883 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Added channel key re-key support. The re-key is perfomed
4888 only by the router and is done once in an hour. Added `rekey'
4889 field to the SilcChannelEntry in the server. Affected files
4890 silcd/server.c and silcd/idlist.h.
4892 * Added silc_task_unregister_by_context into the file
4893 lib/silcutil/silctask.[ch].
4895 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Added SILC_UMODE_GONE mode to indicate when the client is not
4898 present in the SILC network. Added also support to the local
4899 command AWAY that will set this mode. Added support of showing
4900 "xxx is gone" in WHOIS command. The USERS command shows the
4901 gone status as well.
4903 * Fixed setting server and router operator privileges in the
4904 server's UMODE command. Affected file silcd/command.c.
4906 * Merged the SKE KE1 and KE2 payloads into one payload. The
4907 new KE payload is equivalent to the old KE2 payload.
4909 Cleaned up the SKE Start Payload parsing. It now uses the
4910 simple buffer unformatting to do the parsing. A lot faster
4913 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4914 to the SKE that is used to indicate whether both of the SKE
4915 parties should perform authentication. By default only the
4916 responder performs authentication. By setting this flag also
4917 the initiator must do authentication. By default it is unset
4918 since in normal SKE case, client to server connection, only
4919 the responder should do authentication. When doing SKE between
4920 two clients both should perform authentication. Updated the
4921 code and the protocol specs.
4923 * A little fix to IDENTIFY command in the server. Search the
4924 client first by hash not nickname. Affected file is
4927 * Fixed the silc_client_close_connection to support closing
4928 the client to client connections wihtout deleting too much
4929 data. Affected file lib/silcclient/client.c.
4931 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4932 are received if protocol used to be active but is not anymore
4933 the application would crash due to NULL pointer dereference.
4934 Affected files silcd/server.c and lib/silcclient/client.c.
4936 * Added `hash' field to the SilcClientConnection to include
4937 the hash function negotiated in the SKE protocol.
4939 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4940 to set the channel founder authentication data. A client can
4941 claim the founder rights later by providing the authentication
4942 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4943 This way the channel founder can regain the channel founder
4944 privileges even it is left the channel. This works only on
4945 local server and the client must be connected to the same
4946 server to be able to regain the founder rights. Updated the
4947 protocol specs accordingly.
4949 Added support to the CMODE command in the client to set the
4950 founder auth data. Read the README to see how to set it.
4952 Added support to the CUMODE command to claim the founder
4953 rights. Read the README to see how to do it.
4955 Added support for the founder authentication to the Channel
4956 Entry in the server. Affected file silcd/idlist.h.
4958 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4959 server's CMODE command. Affected file silcd/command.c.
4961 * Added the following new functions into lib/silccore/silcauth.[ch]:
4962 silc_auth_get_method and silc_auth_get_data.
4964 * The server now saves the remote hosts public key to the
4965 SilcIDListData pointer. Affected file silcd/protocol.c.
4967 * The normal server now does not remove the channel entry from
4968 the cache if the founder authentication data is set. It used
4969 to remove it if the founder was the last one on the channel on
4970 the server and left the channel. The auth data is saved and
4971 if the channel is re-joined later the old entry is used with
4972 the old auth data. Affected files silcd/command_reply.c and
4975 * Removed the `pkcs' field from the SilcIDListData structure
4976 in the server; it is not used. Affected file silcd/idlist.h.
4978 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Fixed packet processing on slow links. Partial packets were
4981 never re-processed because the incoming data buffer was cleared
4982 by the application. Application must not directly clear the
4983 sock->inbuf, the packet processing routines handle it. Fixed
4984 this in client library and in server.
4986 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Fixed the WHOIS and IDENTIFY send reply function to really
4989 check whether to send list or just one entry. Affected file
4992 * Cleaned up the LEAVE command's channel key distribution. The
4993 affected file silcd/command.c.
4995 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4996 can enforce the channel mode as well. In that case the ID
4997 includes the ID of the server. The code now enforces the
4998 mode change if the router have different mode than the server.
5000 * The notify client operation with CMODE_CHANGE notify can now
5001 return NULL client_entry pointer if the CMODE was not changed
5002 by client. Application must check for this.
5004 * Added <Server ID> argument to INFO command to support server
5005 info fetching by Server ID.
5007 * Added silc_server_announce_get_channel_users to get assembled
5008 packets of channel users of the specified channel. Affected
5009 file silcd/server.[ch].
5011 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5012 was freed underneath the ID Cache.
5014 * Re-announce clients when the server received CHANNEL_CHANGE
5015 notify from the router. Affected file silcd/packet_send.c.
5017 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5020 crashed since it did not handle the fact that there is no cipher
5021 called "3" and didn't check the error condition. Now fixed.
5023 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5024 flag. It can be used to send message requests.
5026 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5028 * Implemented the RESTART command in the client.
5030 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5031 notice type messages. Added notice printing to the user
5034 * The channel keys are not re-generated if the channel's mode
5035 is PRIVKEY, ie private key on the channel exists. Affected
5036 files silcd/server.c and silcd/command.c.
5038 * Fixed a little bug in channel message delivery when channel
5039 private keys are set in the server. Affected file is
5040 silcd/packet_send.c.
5042 * Changed the setting on channel->on_channel = TRUE from the
5043 silc_client_save_channel_key to the JOIN command reply. The
5044 key payload is not received if the private channel key is set.
5045 Affected file lib/silcclient/command_reply.c and the
5046 lib/silcclient/client_channel.c.
5048 * When the CMODE_CHANGE notify is sent and the channel private
5049 key mode is removed the channel key must be re-generated in
5050 other cells as well. Added this support for the router in the
5051 silcd/packet_receive.c.
5053 * Added new local command NOTICE to send notice message on
5054 channel. Affected file silc/local_command.[ch].
5056 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added new local command ME to the client. It is used to send
5059 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5060 some action. Affected file silc/local_command.[ch].
5062 * Changed channel_message and private_message client operations
5063 to deliver the message flags to the application. Added also
5064 the `flags' arguments to the silc_client_send_channel_message
5065 and silc_client_send_private_message functions. Affected file
5068 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Redefined the Private Message Payload to support private message
5071 keys and to support the new private message flags. Updated
5072 the protocol specs. Flags makes it possible to have for example
5073 CTCP style messages.
5075 * Added new type SilcPrivateMessagePayload and defined an API
5076 for it in the lib/silcclient/silcprivate.[ch].
5078 * Tested private message private keys successfully. Tested the
5079 private message key set, unset and list commands with the new
5082 * Redefined the Channel Message Payload to include the channel
5083 message flags (equal with private message flags) to support
5084 for example CTCP style messages.
5086 * Defined some of the message (for channel and private message)
5087 flags. Updated the protocol specs and added the flags to the
5088 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5090 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Added SilcKeyAgreementStatus type to the key agreement routines
5093 to indicate the current status and error if one occured.
5094 The status types are defined in the lib/silcclient/silcapi.h.
5096 * Added new local command KEY that is used to set and unset private
5097 keys for channels, set and unset private keys for private messages
5098 with remote clients and to send key agreement requests and
5099 negotiate the key agreement protocol with remote client. The
5100 key agreement is supported only to negotiate private message keys,
5101 it currently cannot be used to negotiate private keys for channels,
5102 as it is not convenient for that purpose.
5104 * Fixed a minor pending callback setting bug in the function
5105 silc_client_get_client_by_id_resolve, now the function works.
5106 Affected file lib/silcclient/idlist.c.
5108 * Added function silc_net_get_local_port to get local bound
5109 port by socket. Added to lib/silcutil/silcnet.[ch].
5111 * Added `sockets' and `sockets_count' fields to the SilcClient
5112 object. They hold the sockets of the listenning sockets in
5113 the client. Listenning sockets may be for example the key
5114 agreement server. Affected file lib/silcclient/client.[ch].
5115 Added functions the silc_client_add_socket and the
5116 silc_client_del_socket. They are exported to the application
5119 * Added ~./silc/clientkeys to support other client's public keys.
5121 * Renamed verify_server_key client operation to verify_public_key
5122 and added one argument to indicate the type of the connection
5123 (server, client etc.).
5125 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Added silc_server_connection_auth_request to handle the
5128 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5129 silcd/packet_receive.[ch].
5131 * Added silc_server_send_connection_auth_request into the
5132 silcd/packet_send.c to send the connection auth request packet.
5134 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5137 * Fixed the public key authentication in responder side in the
5138 server. The `auth_data' pointer includes the SilcPublicKey
5139 not the path to the public key. Affected file silcd/protocol.c.
5141 * Implemented the public key authentication in the initiator side
5142 in the server. Affected file silcd/protocol.c.
5144 * Removed the [RedirectClient] config section from the server
5145 configuration. Is not needed and I don't want to implement it.
5147 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Cleaned up the CMODE command in the server. It now works
5150 correctly and supports all the modes defined in the protocol.
5151 Affected file is silcd/command.c.
5153 * Added `hmac_name' field to the SilcChannelEntry in the server
5154 to hold the default HMAC of the channel. It can be set when
5155 creating the channel (with JOIN command). Affected files
5158 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5159 type to indicate the change of the current cipher and hmac
5160 on the channel. Client can safely ignore the <cipher> argument
5161 (if it chooses to do so) since the CHANNEL_KEY packet will
5162 force the channel key change anyway. The <hmac> argument is
5163 important since the client is responsible of setting the new
5164 HMAC and the hmac key into use.
5166 * Fixed the CMODE command in the client library as well.
5168 * Tested CMODE command in router environment successfully.
5170 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Show the version of the remote client (or server) when connecting
5173 to the server. It is logged to the log file. Affected file
5174 is silcd/protocol.c.
5176 * Fixed the KILLED notify handling in the client library. The
5177 client must be removed from all channels when receiving the
5180 Also, do not remove the client entry when giving the KILL
5181 command but when the KILLED notify is received.
5183 * Removed silc_idlist_find_client_by_nickname from the server.
5184 Not needed anymore. Affected files silcd/idlist.[ch].
5186 * Implemented the CHANNEL_CHANGE notify type handling to the
5187 server. Affected file silcd/server.c.
5191 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Added silc_server_send_notify_invite to send the INVITE
5194 notify between routers.
5196 * Implemented the INVITE command correctly to the server.
5198 * Implemented the INVITE notify type handling in the server.
5200 * Implemented the INVITE command to the client library and on the
5203 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Added function silc_server_get_client_resolve to find the
5206 client entry by ID from all ID lists and then resolve it
5207 (using WHOIS) if it cannot be found. Affected file is
5210 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Implemented the BAN command to the client library.
5214 * The JOIN command in the server now checks the invite list
5217 * Changed the silc_command_reply_payload_encode_va and the
5218 silc_command_payload_encode_va to support that if argument is
5219 NULL it ignores and checks the next argument. Affected file
5220 lib/silccore/silccommand.c.
5222 * Added silc_server_send_notify_ban to send the BAN notify
5223 type between routers.
5225 * Chaned the silc_notify_payload_encode to support that if
5226 argument is NULL it ignores and checks the next argument.
5227 Affected file lib/silccore/silcnotify.c.
5229 * Tested ban lists in router environment successfully.
5231 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Implemented BAN command to the server, in silcd/command.[ch].
5235 * Removed the BAN and INVITE_LIST modes from the CMODE command
5238 * Added function silc_string_match to regex match two strings.
5239 Affected files lib/silcutil/silcutil.[ch].
5241 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Redefined parts of the SilcChannelEntry in the server to support
5244 the new ban and invite lists.
5246 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Redefined the INVITE command. The same command can be used to
5249 invite individuals to the channel but also to manage the invite
5250 list of the channel (to add to and remove from the invite list).
5251 Updated the protocol specs.
5253 * Added new command SILC_COMMAND_BAN that can be used to manage
5254 the ban list of the channel. Updated the protocol specs.
5256 * Removed the channel modes: the SILC_CMODE_BAN and the
5257 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5258 in the CMODE command. The equivalent features are now available
5259 using INVITE and BAN commands. Updated the protocol specs.
5261 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5262 in the network about change in the current ban list. The notify
5263 type is not used by the client.
5265 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5266 support the invite lists.
5268 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Added new function silc_string_regexify that converts string
5271 including wildcard characters into regex string that can
5272 be used by the GNU regex library. Added into the file
5273 lib/silcutil/silcutil.[ch].
5275 Added silc_string_regex_combine to combine to regex strings
5276 into one so that they can be used as one regex string by
5277 the GNU regex library. Added into the file
5278 lib/silcutil/silcutil.[ch].
5280 Added silc_string_regex_match to match two strings. It returns
5281 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5283 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Imported GNU regex to the soruce tree into lib/contrib.
5286 Fixed some compiler warning from the regex.c.
5288 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Fixed MOTD command in the server to work in router environment.
5292 * Fixed the MOTD command in the client library to support
5293 the server argument in the command.
5295 * Added `nickname_len' argument to the silc_idlist_add_client
5296 in the server, as the `nickname' argument may be binary data
5299 * Added silc_idlist_get_channels to return all channels from
5302 * Implemented LIST command to the server. Affected file is
5305 * Implemented the LIST command to the client library and on the
5308 * Added [<user count>] argument to the LIST command reply.
5309 With private channels the user count is not shown.
5311 * Updated TODO and README.
5313 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * The client entry's data.registered must be TRUE even with
5316 global client entry on global client list. The data.registered
5317 is used to check whether the client is anymore in the network,
5318 for example with WHOWAS command so it must be valid.
5320 * Fixed the WHOWAS command in the server. It now actually works
5321 in router environment. Added function into silcd/command_reply.c
5322 silc_server_command_reply_whowas_save.
5324 * Added silc_idlist_purge function to the silcd/idlist.c
5325 to periodically purge the ID Cache.
5327 * Fixed INFO command in the server. It works now in router
5328 environment. Added <server name> argument to the INFO command
5329 reply. Updated the protocol specs.
5331 * Fixed minor bug in silc_idcache_purge to not purge if the
5332 expire value is zero.
5334 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5335 they were buggy because of the WHOWAS information.
5337 * Fixed local command MSG to handle the async resolving of
5338 the remote client properly. It used to fail the first MSG.
5339 Affected file silc/local_command.c.
5341 * Added `data_len' field to SilcIDCache context.
5343 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Update TODO. Todo in commands in the server.
5347 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5350 used by routers as broadcast packet to inform other routers
5351 about the changed user mode.
5353 Implemented the notify handling in the server. Affected file is
5354 silcd/packet_receive.c. Added the function
5355 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5357 * Added new generic Channel Payload and deprecated the New Channel
5358 Payload. The New Channel Payload is now the generic Channel
5361 * Added new argument `mode' to the silc_server_send_new_channel
5362 as it is required in the Channel Payload now.
5364 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5365 and created a new and real SilChannelPayload to represent the
5366 new generic Channel Payload. Implemented the encode/decode
5367 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5369 * Added silc_server_get_client_channel_list to return the list
5370 of channels the client has joined for WHOIS command reply.
5371 Affected file silcd/server.[ch].
5373 * Implemented the channel list sending in the WHOIS command reply
5374 in server and in the client.
5376 Implemented the channel list displaying on the user interface
5377 as well. Affected file silc/client_ops.c.
5379 * Added silc_channel_payload_parse_list to parse list of Channel
5380 Payloads. It returns SilcDList list of SilcChannelPayloads.
5381 Client for example can use this function to parse the list of
5382 channels it receives in the WHOIS command reply. The caller
5383 must free the list by calling silc_channel_payload_list_free.
5384 Affected files lib/silccore/silcchannel.[ch].
5386 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Added one new argument <user mode> to the WHOIS command reply
5389 to return the mode of the user in SILC. Updated the protocol
5392 Implemented it to the server and client.
5394 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Fixed the mode printing on the user interface on joining.
5397 Affected file silc/client_ops.c.
5399 * Implemented the UMODE command and user modes in general to the
5400 client library and to the user interface.
5402 * Implemented the UMODE command to the server.
5404 * The server now sends UNKNOWN_COMMAND error status if client sends
5405 unknown command. Affected file silcd/command.c.
5407 * All server commands now handle the command identifier the right
5408 way when sending the command reply to the client. The client can
5409 use to identify the command replies with the identifier.
5411 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Added silc_server_get_client_route to resolve the route to
5414 the client indicated by the client ID. Affected file is
5417 * Added silc_server_relay_packet as general function to relay
5418 packet to arbitrary destination. This deprecates functions
5419 like _send_private_message_key, _relay_notify etc. Affected
5420 file is silcd/packet_send.[ch].
5422 Removed silc_server_send_key_agreement,
5423 silc_server_send_private_message_key and
5424 silc_server_packet_relay_notify functions from the file
5425 silcd/packet_send.[ch].
5429 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5430 server. Affected file silcd/packet_receive.[ch].
5432 * Implemented the KILL command to the client. Implemented the
5433 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5434 Affected files lib/silcclient/command[_reply].c and
5435 lib/silcclient/client_notify.c. Implemented the KILL notify
5436 printing in the user inteface.
5438 * Fixed a lot silc_parse_nick memory leaks from the client
5439 library in the file lib/silcclient/command.c.
5441 * Changed the silc_server_send_notify_on_channels's `sender'
5442 argument from SilcSocketConnection to SilcClientEntry to
5443 check the sender as entry and not as connection object and not
5444 to send to the client provided as argument. The affected file
5445 is silcd/packet_send.[ch].
5447 * The notify packets that are destined directly to the client used
5448 to not to be processed by the server. Now changed that and the
5449 server processes all notify packets. After relaying the packet
5450 to the client the notify packet is processed in the server.
5452 * The silc_server_free_client_data now checks whether there is
5453 pending outgoing traffic for the client and purges the data to
5454 the network before removing the client entry.
5456 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5459 an client is killed from the SILC Network. Updated the protocol
5462 Added new function silc_server_send_notify_killed to the
5463 silcd/packet_send.[ch].
5465 * Added function silc_server_packet_relay_notify to relay notify
5466 packets that are destined directly to a client. In this case
5467 the server does not process the notify packets but merely relays
5468 it to the client. Affected file silcd/packet_send.[ch].
5470 Added also silc_server_packet_process_relay_notify to check
5471 whereto relay the notify. Affected file is
5472 silcd/packet_receive.[ch].
5474 * Implemented the KILL command to the server.
5478 * Added the backup schema desgined last fall to the protocol
5479 specs for everyone to see. The specification is in the
5480 *-spec-xx.txt draft and the packet type definitions for the
5481 backup routers is in *-pp-xx.txt draft. Thusly, added also
5482 new packet type SILC_PACKET_CELL_ROUTERS.
5484 * A big security problem in the implementation discovered. The
5485 signoff of an client did not cause new channel key generation
5486 which it of course should've done. The channel keys must be
5487 always re-generated when client leaves (or signoffs) the channel.
5488 The silc_server_remove_from_channels funtion now handles
5489 the channel key re-generation.
5491 * Added `sender' argument to the silc_server_send_notify_on_channels
5492 to not to send the client provided as argument. Affected file
5493 silcd/packet_send.[ch].
5495 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Implemented OPER and SILCOPER commands into the server and
5500 * Added silc_auth_verify and silc_auth_verify_data to verify
5501 the authentication directly from the authentication payload.
5502 It supports verifying both passphrase and public key based
5503 authentication. Affected file lib/silccore/silcauth.[ch].
5505 * Added `hash' field to the SilcIDListData structure. It is the
5506 hash negotiated in the SKE protocol. Affected file is
5509 * Slight redesigning of the SilcAuthPayload handling routines.
5510 Do not send SilcPKCS but SilcPublicKey as argument.
5512 * Implemented the public key authentication support to the
5513 serverconfig. The public key is loaded from the provided path
5514 and saved as authentication data to void * pointer. Thus,
5515 changed the unsigned char *auth_data to void *auth_data;
5517 * Fixed SHUTDOWN command to send the reply before the server
5518 is shutdown. :) Affected file silcd/command.c.
5520 * Fixed fatal bug in CONNECT command. The hostname was invalid
5521 memory and server crashed. Affected file silcd/command.c.
5523 * Fixed fatal bug in CLOSE command. The server_entry became
5524 invalid but was referenced later in the command. Affected file
5527 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Fixed fatal bug in failure packet handling. Server ignored
5530 the failure and thus crashed when it came.
5534 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5537 that the command may be executed only once in (about) 2 seconds.
5538 The old SILC_CF_LAG flag is same but allows command bursts up
5539 to five before limiting.
5541 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5542 server code. Various commands now includes the CF_LAG_STRICT
5543 flag to disallow any kind of miss-use of the command.
5545 * Fixed the silc_buffer_unformat to not to allocate any data
5546 if the length of the data is zero. It used to allocate the
5547 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5549 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Changed the format of AdminConnection configuration section
5552 in the server. Added username of the admin to the format.
5553 Affected files silcd/serverconfig.[ch].
5555 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5556 to return admin configuration data by host, username and/or
5559 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Implemented WHOWAS command to the server. Added the functions:
5563 silc_server_command_whowas_parse,
5564 silc_server_command_whowas_send_reply,
5565 silc_server_command_whowas_from_client and
5566 silc_server_command_whowas_from_server
5568 * Added <Client ID> argument to the WHOWAS command reply. Updated
5569 the protocol specs accordingly.
5571 * Implemented WHOWAS command and command_reply to the client
5574 Implemented the WHOWAS printing on the user interface.
5576 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Added new argument to the WHOWAS command reply, the real name.
5579 It is an optional argument. Updated the protocol specs.
5581 * Added SilcIDCacheDestructor callback that is registered when
5582 the SilcIDCache is allocated. The callback is called when
5583 an cache entry in the ID Cache expires, or is purged from the
5584 cache. Added into lib/silccore/idcache.[ch].
5586 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5587 to destruct the client entries when the cache entry expires.
5588 Other ID Cache's in server and in the client library ignores
5591 * If the ID Cache entry's `expire' field is zero then the entry
5592 never expires. Added boolean `expire' argument to the
5593 silc_idcache_add function in the lib/silccore/idcache.[ch].
5594 If it is TRUE the default expiry value is used.
5596 * Added silc_server_free_client_data_timeout that is registered
5597 when client disconnects. By default for 5 minutes we preserve
5598 the client entry for history - for WHOWAS command.
5600 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added support to the server to enforce that commands are not
5603 executed more than once in 2 seconds. If server receives
5604 commands from client more frequently, timeout is registered
5605 to process the commands. Affected file silcd/command.c.
5606 Added new function silc_server_command_process_timeout.
5608 * Changed NICK_NOTIFY handling in client library to check that
5609 if the client's nickname was changed, so there is no need to
5610 resolve anything from the server.
5612 * Removed error printing from the WHOIS and IDENTIFY commands.
5613 If error occurs then it is ignored silently in the client library.
5614 The application, however, may map the received error to
5615 human readable error string. The application currently maps
5616 the NO_SUCH_NICKNAME error to string.
5618 * Made the command status message public to the application. Moved
5619 them from lib/silcclient/command_reply.c to
5620 lib/silcclient/command_reply.h. The application can map the
5621 received command status to the string with the
5622 silc_client_command_status_message function.
5624 * Added check to the server to check that client's ID is same
5625 as the Source ID in the packet the client sent. They must
5628 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Added dist-bzip hook to the Makefile.am to make bzip2
5631 compressed distributions.
5633 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Server now enforces the maximum length for the nickname and
5636 the channel as protocol specification dictates. 128 bytes for
5637 nickname and 256 bytes for channel name.
5639 * Moved the WHOIS printing to the application. The client libary
5640 does not print out the WHOIS information anymore, the application
5641 must do it. Renamed silc_client_command_reply_whois_print to
5642 the silc_client_command_reply_whois_save.
5644 The client's idle time is also sent to the application now, and
5645 the idle is shown on screen.
5647 * Added silc_client_command_reply_identify_save to save the
5648 received IDENTIFY entries.
5650 * Do not check for channel private keys in message sending and
5651 reception if the channel does not have the PRIVKEY mode set.
5652 Affected file lib/silclient/client_channel.c.
5654 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5657 just surfaced after chaning the JOIN procedure.
5659 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Added silc_client_get_clients_by_list to get client entries
5662 from Client ID list, that is returned for example by JOIN
5663 and USERS command replies. The application should use this
5664 function for example when JOIN command reply is received to
5665 resolve the clients already on the channel (library does not
5666 do that anymore as USERS command reply is not used in the JOIN
5667 procedure anymore). Affected files lib/silcclient/silcapi.h and
5668 lib/silcclient/idlist.c.
5670 * JOIN command reply and USERS command reply returns now SilcBuffer
5671 pointers instead of unsigned char pointers when returning
5672 the client list and mode list.
5674 * Added <Client ID> argument to the JOIN command reply, mainly
5675 for the server to identify for which client the command was
5676 originally sent. Updated protocol specs accordingly.
5678 * Added SilcDlist private_key pointer to the SilcChannelEntry
5679 in the client to support the channel private keys. Affected
5680 file is lib/silcclient/idlist.h.
5682 * Added SilcChannelPrivateKey argument to the function
5683 silc_client_send_channel_message so that application can choose
5684 to use specific private ke if it wants to. If it is not provided,
5685 the normal channel key is used, unless private keys are set.
5686 In this case the first (key that was added first) is used
5687 as the encryption key.
5689 * Implemented the support for channel private key handling.
5690 Implemented the following functions:
5692 silc_client_add_channel_private_key,
5693 silc_client_del_channel_private_keys,
5694 silc_client_del_channel_private_key,
5695 silc_client_list_channel_private_keys and
5696 silc_client_free_channel_private_keys
5698 Affected file lib/silcclient/client_channel.c.
5700 * Added the support for the private keys in the channel message
5701 sending and encryption and in the message reception and
5702 decryption. Affected funtions are
5703 silc_client_send_channel_message and silc_client_channel_message.
5705 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5707 * Added SKE's key verify callback to the client library's
5708 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5710 * Removed the statement that server (or router) must send USERS
5711 command reply when joining to the channel so that the client
5712 knows who are on the channel. Instead, the client list and
5713 client's mode list is now sent in the JOIN command reply to the
5714 client who joined channel. This is better solution.
5716 * Added function silc_server_get_users_on_channel and function
5717 silc_server_save_users_on_channel to the silcd/server.[ch].
5719 * Removed function silc_server_command_send_users from the
5722 * Do not show topic on the client library anymore. The topic is
5723 sent in the command reply notify to the application and the
5724 application must show the topic now.
5726 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Added client searching by nickname hash into the IDENTIFY and
5729 WHOIS commands in the server as they were clearly missing from
5730 them. Affected file is silcd/command.c.
5732 * Fixed a bug in private message receiving in the client library.
5733 The remote ID was freed and it wasn't supposed, now it is
5736 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Minor fix to the channel payload; allocate the data area, as it
5739 needs to be of specific length.
5741 * If the key agreement port is zero then the operating
5742 system will define the bound port. Affected files are
5743 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5745 * Added new function silc_channel_payload_decrypt into the file
5746 lib/silccore/silcchannel.[ch].
5748 * Moved the channel message etc, check from silc_packet_decrypt
5749 to applications. The library calls now a generic
5750 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5751 when the packet is either normal or special. This was done to
5752 allow more wide range of checking that was not allowed when
5753 the code was in library. Now applications can do virtually any
5754 checks to the packet and return to the library the decision how
5755 the packet should be processed. Affected files are
5756 lib/silccore/silcpacket.[ch].
5758 Added silc_server_packet_decrypt_check to the server and
5759 silc_client_packet_decrypt_check to the client library.
5761 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5762 to send with specified source and destination information.
5764 * Channel message delivery between routers was broken after the
5765 channel key distribution was fixed earlier. The channel key
5766 was used be to distributed to other routers as well which is not
5767 allowed by the protocol. Now this is fixed and channel keys
5768 really are cell specific and the channel message delivery between
5769 routers comply with the protocol specification.
5771 * Fixed various commands in server to check also the global list
5772 for the channel entry and not just the local list. The affected
5773 file silcd/command.c.
5775 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Added assert()s to buffer formatting and unformatting routines
5778 to assert (if --enable-debug) when error occurs. Affected
5779 file: lib/silcutil/silcbuffmt.c.
5781 * Changed to auto-reconnect to check whether the remote host is
5782 router and register the re-connect timeout if it is. It used
5783 to check that whether we are normal server, but router must do
5784 auto-reconnect with another router as well. Affected file
5787 * Removed the [<key len>] option from CMODE command as the cipher
5788 name decides the key length, nowadays. See the defined ciphers
5789 from the protocol specification.
5791 * Added [<hmac>] option to the CMODE command to define the HMAC
5792 for the channel. Added SILC_CMODE_HMAC channel mode.
5794 * Added [<hmac>] option for the JOIN command so that user can
5795 select which HMAC is used to compute the MACs of the channel
5798 * Added Hmac field to the Channel Message Payload. The integrity
5799 of plaintext channel messages are now protected by computing
5800 MAC of the message and attaching the MAC to the payload. The
5801 MAC is encrypted. Now, it is clear that this causes some
5802 overhead to the size of the packet but rationale for this is that
5803 now the receiver can verify whether the channel message decrypted
5804 correctly and also when private keys are set for the channel the
5805 receiver can decrypt the packet with several keys and check from
5806 the MAC which key decrypted the message correctly.
5808 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5809 lib/silccrypt/silccipher.[ch].
5811 * Added silc_hash_len to return the digest length into the
5812 lib/silcrypt/silchash.[ch].
5814 * Rewrote parts of Silc Channel Payload interface in the
5815 lib/silccore/silcchannel.[ch]. The encode function now also
5816 encrypts the packet and parse function decrypts it.
5818 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Fixed a minor formatting bug in the SKE's key material processing.
5821 It actually might have processed the keys wrong way resulting
5824 * Redefined the mandatory HMAC algorithms and added new algorithms.
5825 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5826 and hmac-md5 truncated to 96 bits. The mandatory is now
5827 hmac-sha1-96. Rest are optional (including the one that used
5828 to be mandatory). Rationale for this is that the truncated HMAC
5829 length is sufficient from security point of view and can actually
5830 make the attack against the HMAC harder. Also, the truncated
5831 HMAC causes less overhead to the packets. See the RFC2104 for
5834 * Added new [hmac] configuration section. The SKE used to use
5835 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5836 is of course wrong. The official names that must be proposed in
5837 the SKE are the ones defined in the protocol specification
5838 (hmac-sha1-96 for example). The user can configure any hmac
5839 using any hash function configured in the [hash] section. At
5840 least, the mandatory must be configured.
5842 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5844 * Added HMAC list to the SKE proposal list. It has now both
5845 hash algorithm list and HMAC list. This makes the protocol
5846 incompatible with previous versions. The SKE now seems to work
5847 the way it is supposed to work, for the first time actually.
5849 * Defined plain Hash algorithms to the protocol specification.
5852 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Implemented support for key agreement packets into the server.
5855 Added functions silc_server_key_agreement and
5856 silc_server_send_key_agreement. Other than these functions,
5857 server has nothing to do with this packet.
5859 * Added support for private message key packets into the server.
5860 Added functions silc_server_private_message_key and
5861 silc_server_send_private_message_key.
5865 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5866 called in the protocol's final callback instead in the END
5867 protocol state. This makes a little more sense and in the same
5868 time in client we can use the same protocol routines for normal
5869 key exchange and to key agreement packet handling as well.
5871 * Added to both client's and server's KE protocol context the
5872 SilcSKEKeyMaterial pointer to save the key material. We will
5873 bring the key material to the protocol's final callback by doing
5874 this. The final callback must free the key material.
5876 * Added SKE's packet_send callback into client's KE protocol
5877 context so that the caller can choose what packet sending function
5878 is used. This way we can use different packet sending when
5879 doing normal SKE when doing key agreement packet handling (in
5880 the key agreement packet handling we do not want to encrypt
5883 * Implemented the responder side of the key agreement routines
5884 in the client. The client can now bind to specified port and
5885 accept incoming key negotiation. The key material is passed
5886 to the application after the protocol is over.
5888 * Implemented the processing of incoming Key Agreement packet
5889 in the client. Added function silc_client_key_agreement to
5892 * Implemented the intiator side of the key agreement routines
5893 in the client. The client can now initiate key agreement with
5894 another remote client. The key material is passed to the
5895 application after the protocol is over.
5897 * Created client_keyagr.c to include all the key agreement
5900 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5901 SILC_TASK_CALLBACK except that it is not static.
5903 * Created client_notify.c and moved the Notify packet handling
5904 from the client.[ch] into that file.
5906 * Created client_prvmsg.c and moved all private message and
5907 private message key routines from the client.[ch] into that file.
5909 * Create client_channel.c and moved all channel message and
5910 channel private key routines from the client.[ch] into that file.
5912 * Changed silc_client_get_client_by_id_resolve to resolve with
5913 WHOIS command instead of IDENTIFY command, in the file
5914 lib/silclient/idlist.c.
5916 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Implemented the SKE's responder side to the Client library.
5920 * When FAILURE is received to the protocol do not trust it
5921 blindly. Register a timeout to wait whether the remote closes
5922 the connection as it should do it, only after that process the
5923 actual failure. This was changed to both client and server.
5925 * Added client_internal.h to include some of the structures
5926 there instead of client.h in lib/silcclient/.
5928 * Added function silc_task_unregister_by_callback to unregister
5929 timeouts by the callback function.
5931 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Some "Incomplete WHOIS info" errors has been appearing on the
5934 log files. Took away the entry->userinfo check from WHOIS
5935 reply sending. The entry->userinfo is now " " if client did not
5936 provide one. I thought this was fixed earlier but something
5937 is wrong still. Let's see if the error still appears.
5939 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Fixed a minor bug in the login when the channel key is
5942 re-generated in the server. It used to generate the key in
5943 wrong order and thus caused problems in the channel traffic.
5945 * Fixed a minor bug in channel key distsribution after
5946 KICK command. The key was not sent to the router even though
5949 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Added silc_ske_process_key_material_data as generic routine
5952 to process any key material as the SILC protocol dictates. The
5953 function is used by the actual SKE library but can be used by
5954 applications as well. This relates to the private message keys
5955 and the channel private keys since they must be processed the
5956 same way the normal SILC session keys. The protocol dictates
5957 this. Affected files: lib/silcske/silcske.[ch].
5959 Added also silc_ske_free_key_material to free the
5960 SilcSKEKeyMaterial structure.
5962 * Defined silc_cipher_set_key function to set the key for
5963 cipher without using the object's method function. The affected
5964 files: lib/silccrypt/silccipher.[ch].
5966 * Implemented silc silc_client_add_private_message_key,
5967 silc_client_add_private_message_key_ske,
5968 silc_client_del_private_message_key,
5969 silc_client_list_private_message_keys and
5970 silc_client_free_private_message_keys functions in the
5973 Added functions silc_client_send_private_message_key to send
5974 the Private Message Key payload and silc_client_private_message_key
5975 to handle incoming Private Message Key payload.
5977 * Added Cipher field to the Private Message Key payload to set
5978 the cipher to be used. If ignored, the default cipher defined
5979 in the SILC protocol (aes-256-cbc) is used.
5981 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Removed lib/silcclient/ops.h file.
5985 Redefined parts of the SILC Client Library API. Created new
5986 file silcapi.h that deprecates the ops.h file and defines the
5987 published Client Library API. Defined also private message key
5988 API and channel private key API into the file.
5990 This is the file that the application must include from the
5991 SILC Client Library. Other files need not be included by
5992 the application anymore.
5994 * Added new key_agreement client operation callback and also
5995 defined the Key Agreement library API for the application.
5997 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6000 is used by clients to request key negotiation between another
6001 client in the SILC network. If the negotiation is started it
6002 is performed using the SKE protocol. The result of the
6003 negotiation, the secret key material, can be used for example
6004 as private message key.
6006 Implemented the Key Agreement payload into the files
6007 lib/silccore/silauth.[ch].
6009 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Redefined ciphers for the SILC protocol. Added some new ciphers
6012 and defined the key lengths for the algorithms. Changed the
6013 code accordingly. The default key length is now 256 bits.
6015 * Fixed SKE key distribution function silc_ske_process_key_material
6016 when the key length is more than 128 bits. The default key
6017 length in SILC is now 256 bits.
6019 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6020 to indicate unsupported algorithm.
6022 * Renamed rijndael.c to aes.c and all functions as well.
6024 * Fixed a long standing channel key setting bug in client library.
6025 Weird that it has never surfaced before.
6027 * Fixed bug in channel deletion. If the entire channel is removed
6028 then it must also delete the references of the channel entry
6029 from the client's channel list as the client's channel entry and
6030 the channel's client entry share same memory.
6032 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Implemented CONNECT and SHUTDOWN commands in the client.
6036 * Implemented CLOSE command to the client.
6038 * Added the function silc_idlist_find_server_by_name into the
6039 files silcd/idlist.[ch].
6041 Added the function silc_idlist_find_server_by_conn into the
6042 files silcd/idlist.[ch].
6044 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * DIE command was renamed to SHUTDOWN. Updated the both code
6049 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6050 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6052 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6055 * Added function silc_server_create_connection function to create
6056 connection to remote router. My server implementation actually
6057 does not allow router to connect to normal server (it expects
6058 that normal server always initiates the connection to the router)
6059 so the CONNECT command is only good for connecting to another
6062 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6065 or some other client was kicked from the channel.
6067 Implemented the handling of the notify type to both client
6070 Implemented silc_server_send_notify_kicked to send the KICKED
6071 notify. It is used to send it to the server's primary router.
6073 * Implemented the KICK command into server and client.
6075 * Added `query' argument to the silc_idlist_get_client function
6076 to indicate whether to query the client from server or not if
6079 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6080 to indicate that the client is not channel founder.
6084 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Removed the rng context from SilcPacketContext structure and
6087 changed that the packet routine uses the Global RNG API.
6089 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6091 * Added support for quit message that client can "leave" on the
6092 channel when it quits the SILC. It is ditributed inside the
6093 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6095 Added silc_server_free_client_data that will take the
6096 signoff message as argument.
6098 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6100 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Updated parts of the protocol specification to keep it up
6105 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6108 payloads in one packet.
6110 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6111 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6112 use now the new List flag.
6114 * Also deprecated the following packet types: REPLACE_ID,
6115 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6117 * Added list support for Notify packet in server.
6119 * Added silc_server_send_notify_channel_change to send the
6120 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6121 the silc_server_send_replace_id.
6123 * Added silc_server_send_notify_nick_change to send the
6124 NICK_CHANGE notify type. Deprecates the function
6125 silc_server_send_replace_id.
6127 * Added silc_server_send_notify_join to send the JOIN notify type.
6128 Deprecates the function silc_server_send_new_channel_user.
6130 * Added silc_server_send_notify_leave to send LEAVE notify type.
6131 Deprecates the function silc_server_send_remove_channel_user.
6133 * Added silc_server_send_notify_cmode and
6134 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6135 types. Deprecates the silc_server_send_set_mode function.
6137 * Added SERVER_SIGNOFF notify type to indicate that server has
6138 quit. This means that all clients on the channel from that
6139 server will drop. This can be also used when netsplit happens.
6141 Deprecated REMOVE_ID packet type since it is not needed anymore
6144 Added silc_server_send_notify_server_signoff to send the
6145 SERVER_SIGNOFF notify type. Deprecates the function
6146 silc_server_send_remove_id.
6148 Added also silc_server_send_notify_signoff to send the
6149 SIGNOFF notify type.
6151 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6152 SILC protocol from this day on. Changed the protocol
6153 specification as well.
6155 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6156 notify type. It is used between routers to notify about
6157 topic changes on a channel.
6159 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6162 * Partly updated the protocol specification to comply with the
6163 changes now made. It is still though a bit outdated.
6165 * The JOIN notify type now takes one extra argument <Channel ID>.
6166 The packet used to be destined to the channel but now the
6167 JOIN type may be sent as list thus it is impossible to
6168 destine it to any specific channel. By adding this argument
6169 it is again possible.
6171 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Added CREDITS file. The CHANGES and CREDITS file will appear
6174 in the distribution as well.
6176 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6179 types in the server's silcd/packet_receive.c.
6181 * Implemented CMODE and CUMODE to work in router environment.
6183 * Fixed minor encoding and decoding buglet from the
6184 lib/silccore/silcmode.c.
6186 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6189 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6191 * Changed all SilcConfigServer* and silc_config_server* to
6192 SilcServerConfig* and silc_server_config*, respectively.
6195 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Associated the ID (client or server ID) to the Authentication
6198 Payload to avoid any possibility of forging. Updated the
6199 protocol specification and the code accordingly.
6201 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * The RSA key length is now save to the RsaKey context in the
6204 key generation process in lib/silccrypt/rsa.c. The key length
6205 is now used to figure out the maximum size of the block allowed
6206 to be encrypted/signed.
6208 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6209 is equivalent to the silc_mp_mp2bin but does not allocate any
6212 * Changed silc_mp_mp2bin API to take length argument. If it is
6213 non-zero then the buffer is allocated that large. If zero, then
6214 the size is approximated using silc_mp_sizeinbase, which however
6217 * Created Global RNG API which is global RNG that application can
6218 initialize. After initializing, any routine anywhere in the
6219 code (including library) can use RNG without allocating a new
6220 RNG object. This was done to allow this sort of use of the
6221 RNG in code that has no chance to allocate RNG object. All
6222 applications currently allocate this and many routines in the
6223 library use this. Affected file lib/silccrypt/silcrng.[ch].
6225 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6226 it to use the Global RNG API.
6228 * Defined Authentication Payload into protocol specification that
6229 is used during SILC session to authenticate entities. It is
6230 used for example by client to authenticate itself to the server
6231 to obtain server operator privileges.
6233 Implemented this payload into the lib/silccore/silcauth.[ch].
6234 Implemented also routines for public key based authentication
6235 as the new protocol specification dictates.
6237 Moved definitions of different authentication methods from
6238 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6240 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6241 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6242 silc_pkcs_verify_with_hash functions into the file
6243 lib/silccrypt/silcpkcs.[ch].
6245 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * The client entry's userinfo pointer must be always valid.
6248 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6249 will fail since it requires the userinfo. Now, the userinfo
6250 is allocated as "" if actual userinfo does not exist. Actually,
6251 it must exist and it is totally Ok to drop client connections
6252 that does not announce the userinfo. However, we will make
6253 this workaround for now.
6255 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6256 to return the remote port by socket.
6258 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6261 SILC_SERVER_PENDING_EXEC and added an new macro
6262 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6263 data or when error occurs while processing the pending command.
6265 Added new argument `destructor' into silc_server_command_pending
6266 and to the SilcServerCommandPending object. This destructor is
6267 now called after calling the pending callback or if error occurs
6268 immediately. If error occurs the actual pending callback won't
6269 be called at all - only the destructor. The destructor may be
6270 NULL if destructor is not needed.
6272 All this applies for client library code as well. Similar
6273 changes were made there as well for the pending commands.
6275 In the client, the application must now allocate the
6276 SilcClientCommandContext with the silc_client_command_alloc
6279 * Added reference counter to the SilcServerCommandContext. Added
6280 function silc_server_command_alloc and silc_server_command_dup
6283 Same type of functions added to the client library for the same
6286 * Removed the cmd_ident from IDListData away since it is now
6287 global for all connections. It is the command identifier used
6288 in command sending and with pending commands. The affected file
6291 * Added reference counter to the SilcSocketConnection objecet to
6292 indicate the usage count of the object. The object won't be
6293 freed untill the reference counter hits zero. Currently only
6294 server uses this, and client ignores it. The client must be
6295 set to use this too later. The affected files are
6296 lib/silccore/silcsockconn.[ch]. Added also the function
6297 silc_socket_dup to increase the reference counter.
6299 This was mainly added because it is possible that the socket
6300 is removed underneath of pending command or other async
6301 operation. Now it won't be free'd and proper DISCONNECTING
6302 flags, etc. can be set to avoid sending data to connection that
6303 is not valid anymore.
6305 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6306 the connection. After that it sets SILC_SET_DISCONNECTED.
6307 It is, however, possible that the socket data is not still freed.
6308 The silc_server_packet_process now checks that data is not
6309 read or written to connection that is DISCONNECTED. The socket
6310 get's freed when the reference counter hits zero.
6312 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Changed the client operation API: channel_message operation's
6315 `sender' is now the client entry of the sender, not the nickname
6316 and the `channel' is the channel entry, not the channel name.
6318 In the private_message operation the `sender' is now also the
6319 client entry of the sender not the nickname.
6321 Affected file is lib/silcclient/ops.h and all applications
6322 using the client operations.
6324 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Moved the calling of ops->connect() from connect_to_server_final
6327 into receive_new_id functin since that is the point when the
6328 client is actually allowed to send traffic to network. The
6329 affected file is lib/silcclient/client.c.
6331 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6334 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6335 (if needs broadcasting) instead of broadcasting the packets one
6336 by one which would make a burst in the network traffic.
6338 * Added `broadcast' argument to the functions in silcd/server.[ch]
6339 silc_server_create_new_channel[_with_id] to indicate whether
6340 to send New Channel packet to primary router.
6342 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Added new function into the silcd/server.[ch] files:
6345 silc_server_create_new_channel_with_id to create new channel with
6346 already existing Channel ID.
6348 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6349 lib/silccore/silcpacket.h. This packet is used t send list of
6350 Set Mode payloads inside one packet. Server uses this to set
6351 the modes for the channels and clients on those channels, that it
6352 announced to the router when it connected to it. The protocol
6353 specification has been updated accordingly.
6355 * The silc_server_new_channel did not handle the packet coming
6356 from normal server as it normally does not send that. However,
6357 when it announces its channels it does send it. Implemented
6358 the support for that.
6360 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6361 into the file lib/silccore/id.h.
6363 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Fixed memory leaks in the functions silc_idlist_del_client,
6366 silc_idlist_del_channel and silc_idlist_del_server in the file
6367 silcd/idlist.c. All of those leaked like a sieve.
6369 * Fixed some small memory leaks in the client's function
6370 silc_client_notify_by_server.
6372 * Added functions into silcd/server.c: silc_server_announce_clients,
6373 silc_server_announce_channels and silc_server_announce_server.
6374 These functions are used by normal and router server to announce
6375 to its primary router about clients, channels and servers (when
6376 router) that we own. This is done after we've connected to the
6379 These functions effectively implements the following packet types:
6380 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6381 and SILC_PACKET_NEW_ID_LIST.
6383 * Added new functions into the silcd/packet_receive.[ch]:
6384 silc_server_new_id_list, silc_server_new_channel_list and
6385 silc_server_new_channel_user_list to handle the incoming
6386 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6388 * Added support of changing Channel ID in the function
6389 silc_server_replace_id. If the server that announces a channel
6390 to the router already exists in the router (with same name but
6391 with different Channel ID), router is responsible to send
6392 Replace ID packet to the server and force the server to change
6393 the Channel ID to the one router has.
6395 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6396 client that the Channel ID has been changed by the router. The
6397 normal server sends this to the client. Client must start using
6398 the new Channel ID as the channel's ID.
6400 Implemented handling of this new type into lib/silcclient/client.c
6401 into the function silc_client_notify_by_server.
6403 * Added new function silc_idlist_replace_channel_id into the files
6404 silcd/idlist.[ch] to replace the Channel ID.
6406 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Call silc_server_command_identify_check always when processing
6409 the IDENTIFY command in silcd/command.c
6411 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6414 send keepalive packets. The packet can be sent by clients,
6415 servers and routers.
6417 Added function silc_socket_set_heartbeat into the file
6418 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6419 If not set, the heartbeat is not performed. The actual
6420 heartbeat is implemented in the low level socket connection
6421 library. However, application is responsible of actually
6424 Added silc_server_send_heartbeat to send the actual heartbeat
6425 packet into silcd/packet_send.[ch]. Server now performs
6426 keepalive with all connections.
6428 * Added silc_task_get_first function into lib/silcutil/silctask.c
6429 to return the timeout task with shortest timeout. There was a bug
6430 in task unregistration that caused problems. TODO has been
6431 updated to include that task system must be rewritten.
6433 * The client library will now resolve the client information when
6434 receiving JOIN notify from server for client that we know but
6435 have incomplete information.
6437 * Rewrote parts of silc_server_remove_from_channels and
6438 silc_server_remove_from_one_channel as they did not remove the
6439 channel in some circumstances even though they should've.
6441 * Encryption problem encountered in server:
6443 The LEAVE command used to send the Channel Key packet to the
6444 router immediately after generating it. However, the code
6445 had earlier sent Remove Channel user packet but not immediately,
6446 ie. it was put to queue. The order of packets in the router
6447 was that Channel Key packet was first and Remove Channel User
6448 packet was second, even though they were encrypted in the
6449 reverse order. For this reason, MAC check failed. Now, this
6450 is fixed by not sending the Channel Key packet immediately but
6451 putting it to queue. However, this is more fundamental problem:
6452 packets that are in queue should actually not be encrypted
6453 because packets that are sent immediately gets encrypted
6454 actually with wrong IV (and thus MAC check fails). So, packets
6455 that are in queue should be encrypted when they are sent to
6456 the wire and not when they put to the queue.
6458 However, the problem is that the current system has not been
6459 designed to work that way. Instead, the packet is encrypted
6460 as soon as possible and left to the queue. The queue is then
6461 just purged into wire. There won't be any fixes for this
6462 any time soon. So, the current semantic for packet sending
6465 o If you send packet to remote host and do not force the send
6466 (the packet will be in queue) then all subsequent packets to the
6467 same remote host must also be put to the queue. Only after the
6468 queue has been purged is it safe again to force the packet
6471 o If you send all packets immediately then it safe to send
6472 any of subsequent packets through the queue, however, after
6473 the first packet is put to queue then any subsequent packets
6474 must also be put to the queue.
6476 Follow these rules and everything works fine.
6478 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6480 * Added new function silc_server_remove_clients_by_server to
6481 remove all client entries from ID list when the server connection
6482 is lost. In this case it is also important to invalidate all
6483 client entires as they hold the invalid server entry. This
6484 fixes fatal bug when server has lost connection and will reconnect
6487 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Made some sanity checks to silc_server_daemonise like to check
6490 whether the requested user and group actually exists.
6492 * Added sanity check to SKE's silc_ske_responder_finish to check
6493 that the public and private key actually is valid.
6495 * Invalidate the client's nickname when receiving Replace ID
6496 packet and the Client ID is being replaced. This means that the
6497 server will query the nickname if someone needs it (client)
6500 * Sort the ID Cache in client library when the ID Cache data
6501 has changed (needs sorting).
6503 * Do not allow for SILC client to create several connections to
6504 several servers. The client does not support windows right now
6505 and generating multiple connections causes weird behaviour.
6507 Irssi-silc client does support windows and can handle several
6508 connections without problems, see: www.irssi.org and SILC plugin.
6510 * Fixed some places where client was added to the IDList. The
6511 rule of thumb is following (in order to get everything right):
6512 If the client is directly connected local client then the
6513 `connection' argument must be set and `router' argument must be
6514 NULL to silc_idlist_add_client function. If the client is not
6515 directly connected client then the `router' argument must
6516 bet set and the `connection' argument must be NULL to the
6517 silc_idlist_add_client function.
6519 * The funtion silc_server_packet_send_local_channel actually did
6520 not check whether the client was locally connected or not. It
6521 does that now. Fixed a bug related to LEAVE command.
6523 * Fixed Remove Channel User payload parsing bug in server's
6524 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6526 * The server's silc_server_save_channel_key now checks also the
6527 global ID list for the channel as it might not be in the local
6528 list. Fixed a bug related to LEAVE command.
6530 * Is this the end of the [<unknown>] buglet that has been lurking
6531 around for a long time? A little for loop fix in server's
6532 silc_server_command_whois_parse that is used by both IDENTIFY
6533 and WHOIS command. At least, this was a clear bug and a cause
6534 of one type of [<unknown>] buglet.
6536 * WHOIS and IDENTIFY commands call the function
6537 silc_server_command_[whois/identify]_check function even if
6538 we are not router server.
6540 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Added --with-gmp configuration option. If set the GMP
6543 is always compiled in the SILC source tree. If not set then
6544 it is checked whether the system has the GMP3 installed. If
6545 it has then the GMP won't be compiled (the system's headers
6546 and library is used), if it doesn't have it then the GMP is
6547 compiled in the SILC source tree.
6549 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * Changed RSA private exponent generation to what PKCS #1
6552 suggests. We try to find the smallest possible d by doing
6553 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6554 not security fix but optimization.
6556 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Added new config entry [Identity] to fork the server and run
6559 it as specific user and group. A patch from Bostik.
6561 * Imported Dotconf configuration library into lib/dotconf.
6562 This will be used to create the SILC configuration files later.
6563 It will appear in the distsribution after this commit.
6565 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * A big code auditing weekend happening. Auditing code for
6568 obvious mistakes, bugs and errors. Also, removing any code
6571 Removed files for being obsolete:
6573 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6574 inline in the file lib/silcutil/silcbuffer.h)
6576 o lib/silcutil/silcbufutil.c (the header has inline versions)
6578 Changed code to fix possible error conditions:
6580 o The buffer formatting routines now check that the destination
6581 buffer really has enough space to add the data. This applies for
6582 both buffer formatting and unformatting
6583 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6584 unformatting was changed to accomodate following rules:
6585 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6586 sent to the function while XXX_*STRING will not allocate or copy
6587 the data into the buffer. Instead it sets the pointer from the
6588 buffer into the pointer sent as argument (XXX_*STRING used to
6589 require that the pointer must be allocated already). This change
6590 makes this whole thing a bit more consistent and more optimized
6591 (note that the data returned in the unformatting with XXX_*STRING
6592 must not be freed now). The routines return now -1 on error.
6594 o Tried to find all code that use buffer_format and buffer_unformat
6595 and added return value checking to prevent formatting and
6596 especially unformatting errors and possible subsequent fatal
6599 o Changed ske->x and ske->KEY to mallocated pointers in
6600 lib/silcske/silcske.h. Fixed possible data and memory leak.
6602 o Added return value checking to all *_parse* functions. Fixed
6603 many memory leaks as well.
6605 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6606 so that buffer overflows would not happen. All code now also
6607 checks the return value as it can fail.
6609 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Added reconnection support to server if the normal server looses
6612 its connection to the router (for example if router is rebooted).
6613 The server performs normal reconnection strategy implemented
6614 to the server. Affected file silcd/server.c.
6616 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Added new packet type SILC_PACKET_SET_MODE that is used to
6619 distribute the information about changed modes (for clients,
6620 channels and clients channel modes) to all routers in the
6621 network. Updated the protocol specification accordingly.
6623 Added functions into silcd/packet_send.c and
6624 silcd/packet_receive.c: silc_server_send_set_mode,
6625 silc_server_set_mode.
6627 Added new files silcmode.[ch] into lib/silccore that implements
6628 the encoding and decoding of Set Mode Payload. Added new type
6629 SilcSetModePayload. Moved the definitions of different modes
6630 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6632 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Oops, a little mistake in server's connection authentication
6635 protocol. The protocol is not ended with FAILURE but with
6636 SUCCESS if the authentication is Ok. :) Affected file is
6639 * Implemented NICK_CHANGE notify handling in server in the file
6640 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6641 the local clients on the channel. After the changing nickname
6642 in router environment snhould work and the [<unknown>] nickname
6643 should appear no more.
6645 The silc_server_replace_id function that receives the Replace ID
6646 payload now sends the NICK_CHANGE notify type also in the file
6647 silcd/packet_receive.c
6649 * Changed WHOIS and IDENTIFY command to support the maximum amount
6650 of arguments defined in protocol specs (3328 arguments). This
6651 fixed a bug that caused problems when there were more than three
6654 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Added extra parameter, command identifier, to the
6657 silc_client_send_command so that explicit command identifier
6660 Changed that ID list routines uses specific command identifier
6661 when sending WHOIS/IDENTIFY requests to the server so that they
6662 can be identified when the reply comes back.
6664 Affected files lib/silcclient/command.[ch],
6665 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6667 * Added `sender' argument to silc_server_packet_send_to_channel
6668 to indicaet the sender who originally sent the packet to us
6669 that we are now re-sending. Ignored if NULL. Affected file
6670 silcd/packet_send.[ch].
6672 * Added some server statistics support in silcd/server_internal.h
6673 SilcServerStatistics structure and around the server code. Also
6674 send some nice statistics information when client is connecting
6677 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6679 * Fixed channel ID decoding in server's JOIN command reply in
6680 silcd/command_reply.c
6682 * Fixed braodcasting of replace ID payload to not to send it if
6683 we are standalone server in silcd/packet_receive.c.
6685 * Fixed all channel message sending routines to not to send
6686 packets to clients that has router set, since they are routed
6687 separately in the same function earlier. Affects file
6688 silcd/packet_send.c and all channel packet sending functions.
6690 * In USERS reply, res_argv[i] are not allocated, the table
6691 is allocated. Thus changed that free the table, not its
6694 * In server's whois_check and identify_check if the client is
6695 locally connected do not send any WHOIS commands - they are not
6698 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Fixed some minor bugs in client when sending WHOIS command. The
6701 arguments was in wrong order.
6703 * Removed statis function add_to_channel from server in
6704 silcd/command.c that was previously used with the joining but
6707 * Tested USERS command in router environment successfully with two
6708 routers, two servers and two clients.
6710 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Reorganized the USERS command and command reply in client library
6713 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6714 When the command is given by user we register a pending command
6715 callback that will reprocess the command after the reply has been
6716 received from the server. When reprocessing the packet we then
6717 display the information. Thus, the USERS information is displayed
6718 now in the command callback instead of in the command reply
6719 callback. The processing of the command is same as previously
6720 when server has sent the command reply in the JOINing process.
6722 * Added to USERS command in silcd/command_reply.c to join the client,
6723 we didn't use to know about, to the channel after we've created
6724 a client entry for it. Also, for clienet we did know already still
6725 check whether it is on the channel or not and add it if not.
6727 * Removed silc_server_command_join_notify as the function and its
6730 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Changed the client's pending command handling to the same as the
6733 server's pending command handling. It is also now possible to
6734 execute command reply functions from other command reply
6735 function as the function callbacks for commands and command
6736 replies are one and same. The pending commands are not static
6737 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6738 in client connection context. Thus, pending commands are server
6739 connection specific as it is convenient.
6741 Changed the function silc_client_command_pending and
6742 silc_client_command_pending_del and added new function
6743 silc_client_command_pending_check. Removed the
6744 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6747 * Added cmd_ident, current command identifier, to the client
6748 connection context in lib/silcclient/client.h to keep track on
6749 command identifiers used in command sending. Client's command reply
6750 function handling now supports the mandatory command identifiers.
6752 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6753 funtions in client to fully support pending command callbacks.
6755 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6756 as one of the arguments to the application in the command reply
6759 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6760 before first releasing SILC but came back. Now it is removed again
6761 and should come back nomore. The FORWARDED flag was used only
6762 by the JOINing procedure by forwarding the command packet to router.
6763 Now, the JOINing procedure has been changed to more generic (due
6764 to various router environment issues) and FORWARDED is not needed
6765 anymore for anything. The protocol specification is yet to be
6768 Now, removed silc_server_packet_forward from server and the flag
6769 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6771 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Renamed NAMES command to USERS command. The NAMES was named that
6774 due to historical reasons. Now it is renamed. Also, rewrote
6775 parts of the USERS command. The nickname list is not sent anymore
6776 by the server. Only Client ID and mode lists are sent in the USERS
6777 command. Changed this also to the protocol specification.
6779 The client now resolves the names and stuff after it receives
6780 the USERS list from the server when joining to the channel.
6782 * WHOIS and IDENTIFY commands has been changed to support multiple
6783 Client ID's per command. One can now search for multiple users
6784 in the network by sending only one WHOIS or IDENTIFY command.
6785 Changed the code and the protocol specifications.
6787 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6788 uses silc_server_command_whois_parse to parse the request. */
6790 * If normal server, do not parse the WHOIS and IDENTIFY requests
6791 before sending it to the router. Saves some time.
6793 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Fixed JOIN command on client library. Wrong number of arguments
6796 used to crash the client.
6798 * Added silc_server_channel_has_global function to check whether
6799 channel has global users or not.
6801 * Added silc_server_channel_has_local function to check whether channel
6802 has locally connected clients on the channel.
6804 * The silc_server_remove_from_one_channel now checks whether the
6805 channel has global users or not after given client was removed from
6806 the channel. It also checks whether the channel has local clients
6807 on the channel anymore. If it does not have then the channel entry
6808 is removed as it is not needed anymore.
6810 * The silc_server_notify now checks on JOIN notify whether the joining
6811 client is one of locally connected or global. If it is global then
6812 the channel has now global users on the channel and that is marked
6813 to the channel entry. Also, it now saves the global client to
6814 global list who is joining and JOINs it to the channel. This is
6815 for normal server, that is.
6817 Changed silc_server_send_notify_on_channel,
6818 silc_server_packet_relay_to_channel and
6819 silc_server_packet_send_to_channel check if we are normal server
6820 and client has router set (ie. global client) do not send the
6821 message to that client, as it is already routed to our router.
6823 * Implemented LEAVE notify type handling in silc_server_notify
6826 * Tested LEAVE command in router environment successfully. Tested
6827 with two routers, two servers and two clients.
6831 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6833 * Implemented SIGNOFF notify type handling in silc_server_notify
6836 * silc_server_remove_id now removes the client entry from all channels
6837 it has joined and thusly sends SIGNOFF notify type.
6839 * Rewrote the NAMES list generation in server by removing two excess
6840 loops. The lists are created now inside one loop.
6842 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * silc_server_remove_channel_user checks now also global list
6845 for channel and client.
6847 * silc_server_new_channel_user checks now both local and global
6848 list for channel and client. Fixed a bug in client id decoding.
6849 Used to decode wrong buffer.
6851 * silc_server_channel_message checks now both local and global
6852 list for channel entry.
6854 * Tested channel joining (hence JOIN) in router environment
6855 successfully. Tested with two routers, two servers and two
6858 * Tested channel message sending in router environment successfully.
6860 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Added silc_server_save_channel_key into server.[ch] to save the
6863 received channel key in Channel Key payload processing. It is
6864 also used in JOIN command reply handling.
6866 Equivalent function silc_client_save_channel_key added into
6867 client.[ch] into client library.
6869 * Changed JOIN command reply to send information whether the channel
6870 was created or not (is existing already) and the channel key
6871 payload. Changed protocol specs accordingly.
6873 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6874 the request was sent by ID and not by nickname. Crashed on
6877 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6880 now correctly save the received data.
6882 * silc_server_free_sock_user_data now notifies routers in the
6883 network about entities leaving the network.
6885 At the same time implemented functions silc_server_remove_id
6886 and silc_server_send_remove_id to receive and send REMOVE_ID
6887 packets. The packet is used to notify routers in the network
6888 about leaving entities. The ID removed will become invalid in
6891 * Added function silc_idlist_del_server into server. Removes and
6892 free's server entry from ID list.
6894 * silc_server_private_message function now checks, if we are router,
6895 that the destination ID really is valid ID, naturally.
6897 * In router when NEW_ID packet is received (for new client) the
6898 hash of the Client ID is saved in the ID Cache but the
6899 client->nickname is set to NULL, instead of putting the hash
6902 IDENTIFY command now also checks that client->nickname must be
6903 valid. If it is not if will request the data from the server who
6904 owns the client. Added new function
6905 silc_server_command_identify_check.
6907 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6908 to set the command to already allocated Command Payload.
6910 * Tested private message sending in router environment with two
6911 routers, two servers and two clients. Fixed minor bugs and now
6914 * Fixed segfault from client's NAMES command. Used to crash if
6917 * Forwarded packets must not be routed even if it is not destined
6918 to the receiver. Changed server code comply with this.
6920 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6922 * Added `require_reverse_mapping' boolean value to ServerParams
6923 structure. If TRUE (not default) the server will require that
6924 the connecting host has fully qualified domain name.
6926 If the reverse mapping is not required and hostname could not be
6927 found the IP address is used as hostname.
6929 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Implemented version string checking to both client and server.
6932 The check is incomplete currently due to the abnormal version
6933 strings used in development version of SILC.
6935 * Changed all command functions in server to use the new
6938 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Changed char *data to unsigned char *data in ID Cache system to
6941 support binary data as ID Cache data. Changed code to support
6942 binary data in lib/silccore/idcache.c.
6944 * Renamed silc_server_packet_relay_command_reply to
6945 silc_server_command_reply as it is normal packet receiving
6946 function. Rewrote the function to accept command replys for
6947 servers and not only for clients.
6949 * Mark remote router always as registered server if we are connecting
6950 to it. Otherwise, commands sent by the router to us are ignored.
6952 * All ID List find routines now returns the ID Cache Entry pointer
6953 as well if requested.
6955 * WHOIS command works now in router environment, tested with two
6956 routers, two servers and two clients.
6958 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6959 in router environment (as it is almost equivalent to WHOIS) but
6960 hasn't been tested thoroughly. Added new functions:
6962 silc_server_command_identify_parse
6963 silc_server_command_identify_send_reply
6964 silc_server_command_identify_from_client
6965 silc_server_command_identify_from_server
6967 * Disabled route cache adding because adding two different ID's with
6968 same IP replaces the old cache entry thus giving wrong route.
6969 The entry->router->connection is always the fastest route anyway
6970 so route cache may not be needed. Of course, new routes maybe
6971 established after receiving the ID when the entry->router->connection
6972 might not be anymore the most optimal.
6974 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Add route cache for received ID for fast routing.
6978 * Added silc_server_packet_route to route received packet on router
6979 that is not destined to us.
6981 * Renamed silc_server_get_route to silc_server_route_get.
6983 * Added id_string and id_string_len fields into SilcServer to
6984 include encoded ServerID for fast comparing without excess
6985 encoding of the ID's.
6987 * Cleaned up WHOIS command on server side. Added following static
6990 silc_server_command_whois_parse
6991 silc_server_command_whois_check
6992 silc_server_command_whois_send_reply
6993 silc_server_command_whois_from_client
6994 silc_server_command_whois_from_server
6996 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6997 arguments in command replies. All command functions should be
6998 updated to use this macro.
7000 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7002 * Minor typo fixes on command reply handling on server.
7004 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7006 * Added silc_server_command_add_to_channel internal routine to add
7007 the client to the channel after router has created the channel and
7008 sent command reply to the server.
7010 * Added generic silc_server_send_command to send any command from
7013 * Use static buffer with ID rendering instead of duplicating data.
7015 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Fixed a channel user mode bug when joining to a channel server gave
7018 everybody channel founder rights, oops.
7020 * We mark ourselves as the router of the incoming server connection
7021 if we are router ourselves. This way we can check in some packet
7022 sending functions whether it is locally connected server. For
7023 incoming router connections we put NULL.
7025 * For router sending packets locally means now always sending the
7026 packet cell wide; to local clients and local servers. For normal
7027 server sending packet locally means sending it to only local
7030 * Fixed the JOIN command to really work in router environment. If the
7031 channel is created it is always created by the router. Router is
7032 also responsible of making the initial joining to the channel,
7033 sending JOIN notify to the sending server and distributing
7034 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7035 does not exist server doesn't do anything else but forward the
7036 command to the router which performs everything.
7038 * Added silc_server_send_channel_key function to send the Channel Key
7041 * Added silc_server_create_channel_key to create new channel key. The
7042 channel key is now re-generated everytime someone joins or leaves
7043 a channel, as protocol dictates. Note: channel->key_len is the
7046 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7048 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7049 packet_receive.[ch] to separate packet sending and receiving
7050 routines. The server.[ch] now includes everything else including
7051 actual packet processing (writing and reading data) and other
7054 Renamed silc_server_private_message_send_internal to
7055 silc_server_send_private_message. The routine is still though
7056 used only to relay private messages as server does not send
7057 private messages itself.
7059 Renamed silc_server_new_channel to silc_server_create_new_channel
7060 and added new function sicl_server_new_channel that handles the
7061 incoming New Channel packet. Added also new sending function
7062 silc_server_send_new_channel to send New Channel Payload.
7064 * Added new function silc_server_notify to process incoming notify
7065 packet to the server/router. Server may then relay the notify
7066 to clients if needed.
7068 * Added new function silc_server_new_channel_user to process incoming
7069 New Channel User packet. Router will redistribute the packet and
7070 send JOIN notify to its local clients and locally connected servers
7071 if needed. Normal server will send JOIN notify to its local client
7072 on same channel when received this packet. Added also corresponding
7073 sending function silc_server_send_new_channel_user to sent the
7076 * Added boolean route argument to send_notif_to_channel and
7077 packet_send_to_channel functions to attempt to route the packet
7078 if it is TRUE and send only locally if it is FALSE.
7080 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7082 * silc_server_replace_id now broadcasts the received replace ID
7083 packet if it is not broadcast packet already. The router must
7084 broadcast to inform other routers about changed ID.
7086 * Added backpointer to server's router into SilcServer context in
7087 silcd/server_internal.h.
7089 * Fixed silc_server_packet_broadcast to send correct broadcast
7092 * The channel key is now distributed to the local client as soon
7093 as it is received from the router (in router environment) so that
7094 no other packet may be sent for the channel until client has
7097 * silc_server_remove_channel_user now broadcasts the received
7098 Remove Channel User packet if it is not broadcast packet already.
7099 The router must broadcast to inform other routers about removed
7102 * Added users field into SilcPacketContext that is a reference count
7103 of the context. One can increase the reference count by calling
7104 silc_packet_context_dup which is now changed to just increase the
7105 reference count instead of duplicating the data. The reference
7106 count is decresed by calling silc_packet_context_free that will
7107 free the data after the reference count hits zero.
7109 For now on the packet context and everything allocated into it
7110 (including the raw packet from network) must be freed by calling
7111 the new silc_packet_context_free function. Added also new function
7112 silc_packet_context_alloc that must be used now to allocate the
7113 context. This also means that if a routine is asynchronous from
7114 silc_[client/server]_packet_parse_type the packet context must
7115 be duplicated by calling silc_packet_context_dup. Otherwise it
7116 gets free'd after silc_[client/server]_packet_parse_type returns.
7117 Also, one must remember that if packet is duplicated then its
7118 reference count must be decresed by calling the free function as
7119 many times as it was duplicated.
7121 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7122 from both client and server.
7124 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7126 * Made joining to a channel working in router environment.
7128 * Cleaned up JOIN command on server side and create function
7129 silc_server_command_join_channel internal routine to make the
7132 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Changed silc_command_pending list to SilcDList. Also, added
7135 `ident' field to SilcServerCommandPending structure to identify
7136 the reply and to call correct callback.
7138 Added silc_server_command_pending_check function to replace the
7139 corresnponding macro. The silc_command_pending list is not
7142 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7143 to set identifier to previously allocated Command Payload. It
7144 is used to set identifier for command when resending Command
7147 * Added silc_command_payload_encode_payload to encode Command
7148 Payload buffer from SilcCommandPayload structure.
7150 * Added silc_argument_payload_encode_payload to encode Argument
7151 payload buffer from SilcArgumentPayload structure.
7153 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Changed WHOIS command to support router connection on server side.
7156 The whois request is always sent to router unless the server is
7157 standalone server. After server has received the reply from the
7158 router will it send the reply to the client.
7160 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7161 broadcast received broadcast packet. The function is used only
7162 by router. The broadcast packet is always sent to the router's
7165 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7166 render given ID to printable string, for log files for example.
7168 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7170 * Made basic router to router connections working. At least they
7171 can now connect to each other but nothing really works the way
7172 they are supposed - yet.
7174 * Added new initiator token to RouterConnection configuration
7175 file in silcd/serverconfig.[ch]. It is used to tell whether we
7176 are the initiator to the remote router or whether we'll expect
7177 the other end to connect.
7179 * Moved registering of listener task to silc_server_init, hence
7180 the server starts listenning as soon as it is run, even if it
7181 does not have connections to other routers. Let's see how well
7184 * Changed default connection retry timeouts for more suitable in
7187 * Removed cipher and such arguments from silc_idlist_add_client
7188 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7189 Added new function silc_idlist_add_data to add the keys and stuff
7192 * Added SilcIDListData structure and added it to SilcClientEntry
7193 and SilcServerEntry as their first field in the structure. This
7194 way we can explicitly cast the ID entries to the SilcIDListData
7195 structure and get common data for the entries. In past, we had
7196 to first check what type of connection it is and then cast it to
7197 correct ID entry type. Now, we can directly cast the opaque
7198 pointer to the SilcIDListData (no matter what ID entry it actually
7199 is) and get the data needed.
7201 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7204 in some circumstances even if threre were timeout tasks, though not
7205 IO tasks, but tasks anyway. Now fixed.
7207 * Defined SilcServerConnection structure to hold connection specific
7208 stuff about directly connected servers and routers. The definition
7209 is currently in silcd/server_internal.h. I thought about having
7210 a bit more important role fro this struct but for now it is used
7211 only when connecting to other server (or router actually).
7213 * Added connecting retry support in server when connecting to
7214 router(s). The retry feature implement exponential backoff
7215 algorithm. Also, added SilcServerParams structure to hold default
7216 parameters for server. For now, it include these retry settings
7217 and are hard coded. After server is moded to be as Silc Server
7218 Library this structure will be more important.
7220 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Changed client librarys channel->clients table to SilcList and
7223 changed code accordingly.
7225 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * Changed client's channel table to SilcList and changed code
7228 accordingly. Also changed SilcChannelClientEntry to include back-
7229 pointer to the channel so that client entry can use that structure
7230 as list as well and we have fast cross-reference to the channel.
7231 This change dramatically decreased the complexity of channel
7232 handling with client entry and vice versa (removed one extra
7233 loop when searching for channel entry from many functions).
7235 * Changed server->sim from table to SilcDList and changed code
7238 * NAMES command can now be used from user interface. It will show
7239 the user list on the channel, neatly.
7241 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7242 Code now saves realname of the user if it becomes available.
7244 * Renamed configure.in to configure.in.pre and made ./prepare
7245 script to automatically add correct version string to
7246 configure.in which it creates from configure.in.pre.
7248 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * NAMES command reply now shows users mode with the nickname when
7253 * Moved silc_client_ch[u]mode[_char] functions from
7254 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7255 place sucks, they are utility functions and should be in some
7258 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7260 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7263 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7267 * Added TRQ (efficient deque and list library) into lib/trq. This is
7268 a very good list library that is currently used in the SILC. Defined
7269 SilcList API over the library because I didn't like the API very
7270 much. See lib/trq/silclist.h for the API and examples of how to
7271 use the API. Fixed various places in the code to use the new
7272 SilcList API. The SilcList is meant for lists that has a structure
7273 already defined as a list. It is not suitable to add just some
7274 context to the list (in TRQ, the context is the list actually).
7276 So, I defined SilcDList that can be used for the purpose where
7277 predefined list structure does not exit. This can be used as
7278 such list. Now some context just can be added to the SilcDList.
7279 Currently this list is not used in the SILC just yet, though there
7280 are a lot places where this can replace dynamically allocated
7281 tables and I will fix these places, later, to use SilcDList.
7282 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7283 and use TRQ internally).
7285 Also fixed some annoying warning messages that the original TRQ
7286 code generated. Also minor changes to TRQ's Makefile.in.
7288 * Added support for querying by Client ID to both WHOIS and
7289 IDENTIFY commands into server, as required by the protocol.
7291 * Removed method function pointers from SilcBuffer structure. They
7292 weren't used to anything and just increased the context size for
7293 no good reason. This change also made silc_buffer_alloc and
7294 silc_buffer_free functions inline functions.
7296 * Disabled command flooding detection support until it's fixed so
7297 that it accepts commands in but does not execute them more than once
7300 * Added silc_net_localhost(), to return local hostname, into
7301 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7302 that must be initialized before calling silc_client_init.
7304 * Added new function: silc_server_send_notify_on_channels to send
7305 notify messages to all channels client has joined. It is assured
7306 that the message is sent only once per client.
7308 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7309 lib/silcutil/silcutil.[ch] as silc_format function. The new
7310 function is generic and is used by server as well, not only by
7311 the logging routines.
7313 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7314 the provided version string was not acceptable. Added new function:
7315 silc_ske_check_version into lib/silcske/silcske.h. The function
7316 must be implemented by the application (client or server) and it
7317 does not reside in the SKE library. The function checks the version
7318 string remote end sent.
7320 * Added back pointers (to opaque context and to SilcSocketConnection)
7321 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7323 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7324 duplicate packet context structure.
7326 * Changed `notify' client operation to send same arguments as client
7327 receives from server except for ID's. ID's are mapped to correct
7328 ID entry and that is returned. Also, if channel entry is not sent
7329 by server but the notify is for channel the channel entry is sent
7330 to application (otherwise application doesn't know that it is for
7331 channel (library gets it from packet's Destination ID)).
7333 * Added silc_client_remove_from_channels into client library to
7334 remove a client from all channels it has joined to. Used when
7335 received SIGNOFF notify from server. Added also new function
7336 silc_client_replace_from_channels to replace old ID entry with
7337 new ID entry on all channels. Used when received NICK_CHANGE
7340 * Fixed ID Cache list handling in silc_idlist_get_client in
7341 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7342 to get (or query) client by ID.
7344 * Updated TODO list.
7346 * Added connection authentication status message defined by the
7347 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7348 support for these into the code in client and server side.
7350 * Added generic function silc_client_send_command to send any command
7351 with variable argument list. Application should use this function
7352 to send commands if the command functions provided by the library
7353 does not suite for the application's user interface needs.
7355 * Added new `failure' client operation. Application is notified about
7356 received failure packet if client is executing a protocol. In this
7357 case the protocol's execution has failed.
7359 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7360 is required by the protocol.
7362 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7363 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7366 * Added status flag to SilcSKE object to indicate realtime status
7367 of the SKE protocol.
7369 * Application receives now exactly same command reply arguments as
7370 the library receives from server. However, if ID is received the
7371 corresponding ID entry is returned to the application (eg. Client
7372 ID is mapped to correct SilcClientEntry entry and that is returned).
7373 Changed command_reply client operation due to this change.
7375 * Changed all ID's in commands and in command replys as ID Payloads.
7376 Change affected both client and server side codes.
7378 All ID's sent in SILC network (with execption of ID's in SILC
7379 Packet header) are sent in ID Payload to support variable length
7382 * Server now notifies nick changes and notifies all clients on
7383 the channels about the new nickname (about the new Client ID,
7386 * Implemented CMODE command to change channel modes. Supports all
7387 channel modes defined by the protocol specs except ban and invite
7388 lists. (Also, private channel key mode is supported but support for
7389 setting private channel key in client is missing, thus, this mode
7390 has no effect on client side (except that server requires that the
7391 client uses private channel key and normal channel traffic does not
7394 Also, invite mode works per se, but INVITE command does not work
7395 yet correctly, so you can set channel as invite only channel but
7396 inviting clients to the channel does not work (it is yet to be
7397 thought what's the best way to do it).
7399 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7400 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7401 Implemented CUMODE command to change user's mode on the channel.
7402 Supports all modes defined by the protocol specs.
7404 * Added NAMES command reply to return users modes on the channel.
7406 * Removed unnecessary and slow ciphers from lib/silccrypt.
7408 * Set SO_KEEPALIVE option to connection sockets by default.
7410 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7412 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7413 redefined the Notify Payload into protocol specs.
7415 * Added silc_id_payload_parse_id to get ID directly from raw
7418 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7421 accept searching by Client ID as well.
7423 * Added support for LEAVE and SIGNOFF notify types in client library.
7425 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7426 to parse ID Payload from raw data.
7428 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7430 * Added flags parameter into silc_ske_assemble_security_properties
7431 function in lib/silcske/silcske.[ch].
7433 * Changed notify client operation to fit better for notify messages
7434 sent by server. The notify payload received from server is now
7435 passed to the application (after parsing it to SilcNotifyPayload).
7436 It is application's responsibility to retrieve the arguments
7437 from the payload and show the message the way it wants. The message
7438 sent by server is implementation specific.
7440 * Changed public keys to comply with the protocol specification.
7441 Old public keys are not supported anymore and are not compatible.
7443 * Removed nickname from Channel Payload as the latest draft removed
7444 it. The client must resolve the nickname from the NAMES command
7445 reply received when it joined the channel.
7447 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7449 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7451 * Fixed some errors in protocol specification drafts.
7453 * Created lib/silccore/silcnotify.c to implement Notify Payload
7454 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7455 generic payloads described by protocol specifications. The file
7456 includes implementations for ID Payload and Argument Payload.
7458 * Changed Command Payload implementation to use the new Argument
7459 Payload. Changed command_xxxx_payload to command_payload_xxxx
7460 to comply with SILC coding conventions.
7462 * Added suppport for Argument Payload handling in Notify Payload
7463 implementation as protocol requires it. Added the new support
7464 into server and client lib as well.
7466 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Added support for multiple nicknames on same channel. [n] is
7469 added locally to the nickname if there are more than one same
7470 nicknames on the channel.
7472 * Server now sends all nicknames that matched WHOIS request.
7473 Client also shows the list received from server.
7475 * Added TOPIC command to client side. User can now set and show
7476 current topic on channel.
7478 * Added MOTD command to client and server. Also, server sends the
7479 motd when client connects to the server.
7481 * Changed version strings to comply ISO 8601.
7483 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7485 * Fixed protocol error handling in client library. It should now
7486 cope even if the SKE fails for some reason.
7488 * Made new protocol specification drafts for submitting to IETF.
7490 * Implemented TOPIC command to server in silcd/command.c.
7492 * Added two new notify types into lib/silccore/silcnotify.h:
7493 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7494 notify nickname change and topic setting/change on a channel.
7496 * API change of command_reply operation in client library. The
7497 application gets now the status type received from server as well.
7499 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7501 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7503 * Cras fixed and optimized the packet handling even further and
7504 it should work now. Minor change to the prototype of function
7505 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7507 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * Added new function into lib/silcutil/silcschedule.[ch]:
7510 silc_schedule_with_fd to select() a specified fd. The function
7511 returns after timeout expires or data arrives or goes. The
7512 function is used by packet routines to wait that all data is
7513 received from network.
7515 * Fixed data reading from network in lib/silccore/silcpacket.c.
7516 The code now assures that all data is read from the fd and then
7517 continues packet processing. This was a bug fix since the code
7518 used to drop some data in some circumstances.
7520 * Added new function into lib/silcclient/client.[ch]:
7521 silc_client_start_key_exchange to start key exchange after
7522 connection has been established to server. The code internally
7523 now uses this funtion but its main purpose was to provide it
7524 for applications that perform their own connecting. After
7525 application has created a connection it merely calls this
7526 function to start the key exchange between client and server.
7527 The library takes care of everything else after that.
7529 Updated also lib/silcclient/README to explain the usage of
7532 * Do not send to application information that connection has
7533 been established. Application gets notified it by connect
7536 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7538 * Applied cras's patch to add silc_schedule_one function. The
7539 function runs scheduler once and returns.
7541 * Fixed the scheduler after cras messed it up. The timeout
7542 handling works now as it's supposed to work.
7544 * Added into lib/silccore/ silcnotify.h to include notify
7545 message types support. Changed silc_server_send_notify*
7546 functions, in server.[ch], to support those new notify types.
7547 Added the support for the notify types into client library,
7548 as well. Added new notify client operation into ops.h in
7551 * Changed silc_server_packet_send_to_channel to send normal
7552 packets instead of just channel message packets. The function
7553 is now used to send the notify packets to channels. It is not
7554 used to send channel message packets anymore, as server never
7557 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7558 va_arg()s as it seems to require it nowadays. I guess, if SILC
7559 is compiled with older va_arg() the new code should work anyway.
7561 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7563 * Splitted core library. Core library (lib/silccore) includes
7564 now only SILC protocol specific core (and common) components.
7565 Created new utility library (lib/silcutil) that includes more
7566 generic purpose stuff. The stuff for util library was taken
7567 from the old core library. This was minor and easy split.
7569 * Created SILC Client Library (lib/silcclient) that includes
7570 implementation of the SILC client without user interface. This
7571 was major move from silc/ directory. The code has been changed
7572 so that it is transparent towards the user interface. The
7573 silc/ directory includes now the same user interface as before
7574 and it uses the new client library. Read lib/silcclient/README.
7575 Basicly, the client library performs everything else related
7576 to SILC except user interface handling. Also, configuration
7577 files are considered to be part of user interface and library
7578 does not handle them.
7580 This change also changed a lot of structures, function naming etc.
7581 Most important change was that SilcClientWindow object was
7582 renamed to SilcClientConnection in the client library. Created
7583 also new file lib/silcclient/ops.h. Also added new files
7584 silc/local_command.[ch] and silc/client_ops.[ch].
7586 All these changes were made to make it easier for user interface
7587 designers to create what ever user interface for the SILC client
7590 It is also expected that the server will be moved to lib
7591 directory as well and SILC Server Library will be created;
7592 sometimes in the future.
7594 * Removed Local commands from lib/silccore/silccommand.h as
7595 they are application specific and new client library does not
7596 handle any of those anymore.
7598 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7599 old client implementation in silc/.
7601 * Added support for callback functions in SILC_LOG_* macros.
7602 Application can now set its own callbacks that will be called
7603 instead of using the default functions that will always print
7604 the debug messages to stderr (or stdout). Also, debugging can
7605 now be disabled by setting silc_debug to FALSE and re-enabled by
7606 setting it to TRUE. Note, that logging will still work even
7607 if debugging is disabled.
7609 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7610 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7611 silc_log_reset_debug_callbacks.
7613 * To enable debugging in silc client one must give now -d
7614 option on command line.
7616 * Changed silc_schedule_init to automatically allocate task queues
7617 if they are not allocated before calling it.
7619 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7621 * Added GMP 3.1 into math library.
7623 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7626 a channel in SILC network. The packet is used by servers and
7627 routers to notify other routers that user has left a channel.
7628 This little feature was missing until now. Added the feature
7629 to protocol specification as well.
7631 Added functions: silc_server_send_remove_channel_user and
7632 silc_server_remove_channel_user into server.[ch].
7634 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7635 lib/silccore/silcpacket.h. However, they are not implemented
7638 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Fixed joining to a channel and sending channel messages
7641 between server and router. The channel message sending should
7642 now work inside a cell.
7644 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7646 * Fixed the private message sending between server and router.
7647 The private message sending should now work inside a cell.
7649 * Added silc_server_replace_id into server.[ch] to replace
7650 existing ID in the SILC network.
7652 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7653 and silc_idlist_replace_server_id into idlist.[ch] in server.
7655 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7657 * Fixed the server to server connections. Server can again now
7658 connect to router. Router to router connections probably does
7661 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7663 * Added dynamic protocol registering support. Now protocols can
7664 registered and unregistered on the fly. Patch by cras.
7666 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7668 * Added lib/contrib directory to hold routines that some platforms
7669 don't have but are needed by SILC.
7671 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7672 into lin/contrib to provide getopt() and getopt_long() for
7673 those who don't have it.
7675 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Added AWAY command to client. When away message is set and
7678 client receives a private message packet the client automatically
7679 replies to the sender with the away message.
7681 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7682 bug seemed to be the cause of recent problems when compiling
7685 * Added version detection support to SKE protocol specification
7686 and added the new changes to the SKE implementation as well.
7687 There were other minor changes in the SKE protocol as well.
7689 Many changes in lib/silcske/silcske.[ch] and in
7690 lib/silcske/payload.[ch].
7692 * Added ^U functionality, clear input line. Patch from cras.
7694 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Mainly small bugfixes on core library. Fixed some debugging
7697 logging and buffer overflow in silclog.c.
7699 * Updated config.sub and config.guess on the distribution tree.
7701 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7703 * Added command lagging support in server. Client may execute
7704 commands now only once in two seconds.
7706 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7708 * Optimized packet reception. MAC computation and checking is now
7709 also more optimized. A lot previously duplicated code is now
7710 used as generic by both client and server.
7712 * Fixed key pair generation in clientutil.c
7714 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7716 * Added into lib/silccore/silcbufutil.[ch] new function;
7717 silc_buffer_realloc.
7719 * Moved generic packet sending/encryption functions to
7720 lib/silccore/silcpacket.[ch] from client and server. Some
7721 rewriting of the functions.
7723 * Moved all generic packet reception/decryption functions to
7724 lib/silccore/silcpacket.[ch] from client and server. The
7725 packet processing is now much cleaner in both client and server.
7726 These were major changes in both client and server.
7728 * Created many common functions in server to do packet sending.
7729 Previously code were duplicated a lot, this has been removed
7732 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7734 * Rewrote major parts of the ID cache system. Don't know
7735 whether it is better now or not but at least the API is more
7738 * Major rewrite on ID cache stuff on client because of the ID
7739 cache API changes. Added idlist.c to client.
7741 * Also major rewrite on ID cache stuff on server as well.
7742 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7743 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7744 in hand, instead they are all put into the ID cache system now.
7745 All server_idlist_* routines uses ID cache now instead of
7746 traversing its own lists (those lists does not exist anymore).
7747 SilcIDList though still exists. Also, SilcXXXEntry's are
7750 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7752 * Finally made the SKE implementation compliant to the protocol
7753 specification. All mp integers are now binary encoded as
7754 opposed being HEX encoded.
7756 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7759 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7760 functions: silc_[encode/decode]_pem. Also added function
7761 silc_encode_pem_file to PEM encode with newlines ('\n') for
7764 * SILC public keys are now encoded either PEM or binary. Same
7765 option is for private keys as well. By default private keys
7766 are binary encoded and public keys PEM encoded. Silly HEX
7767 encoding were removed.
7769 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7770 function to create fingerprints.
7772 * Fixed a bug in SHA1; does not change the original data anymore.
7774 * Partly implemented INFO command on client and server side.
7775 Fixed CLEAR command. Changes to SERVER command; show current
7776 server(s) when giving command without arguments. Added
7777 VERSION command to client.
7779 * Added check to server that unregistered connections cannot
7780 execute commands (unless it is specificly allowed).
7782 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Fixed screen refresh.
7786 * Fixed channel joining bug from client. On some circumstances
7787 client tried to join to a channel it had already joined.
7789 * Added public key verification process into client's protocol.c.
7790 The client now verifies the public key from user and saves
7791 it into ~./silc/serverkeys/ directory.
7793 Added into: clientutil.[ch]: silc_client_verify_server_key.
7795 * Changed SKE protocol's silc_ske_initiator_finish function
7796 to accept callback function that verifies the received public
7797 key. Removed old silc_ske_verify_public_key function.
7799 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7801 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7802 silc_pkcs_private_key[_data]_set.
7804 * Made the password and public authentication more cleaner in
7805 server's protocol.c.
7807 * Removed historic and obsolete protocol `channel_auth' from
7808 both client and server.
7810 * Removed wrong way of sending command status messages from
7811 server to client in server's command.c. The old way violated
7812 protocol specification.
7814 Changes to silccore/silccommand.[ch]: removed
7815 silc_command_encode_status_payload -> not needed anymore,
7816 changed silc_command_encode_payload_va to accept extra
7817 argument on variable argument list. The argument type must
7818 now be provided to the function. Also, added new function:
7819 silc_command_encode_reply_payload_va which is same as
7820 normal command_encode_payload_va except command status type
7821 is provided as extra argument.
7823 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Added ~./silc directory handling. The directory includes the
7826 public and private keys for the client.
7828 Added silc_client_check_silc_dir, silc_client_create_identifier
7829 and silc_client_load_keys.
7831 * Implemented SILC protocol compliant public key. Added public
7832 and private key saving to and loading from files.
7834 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7835 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7836 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7837 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7838 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7840 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7841 silc_pkcs_load_[public/private]_key.
7843 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7845 * Added silc_server_get_route (route.[ch]) to get connection
7846 data for the fastest route for given ID.
7848 * Implemented INVITE command on client and server. The command
7849 were re-defined in the SILC Protocol Specification and the
7850 implementation now complies with the specification.
7852 * Implemented PING command on client and server.
7854 * Implemented NAMES command on client and server. The server side
7855 supports currently only normal server not router server yet.
7856 Some changes to NAMES definition in SILC protocol specification.
7858 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Implemented LEAVE command on client and server.
7862 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7863 again. This change was made to the protocol as well. Server
7864 should not violate the protocol specification anymore.
7866 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7869 was tested. SOCKS4 was not but should work anyway.
