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

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

782 * Added new configuration options and blocks:
783 keepalive_secs, reconnect_count, reconnect_interval,
784 reconnect_interval_max, reconnect_keep_trying and
785 require_reverser_lookup. Added ConnectionParam block, and
786 implemented the connection parameters when connecting as
787 initiator and when accepting connections as responder.

792 Affected files silcd/serverconfig.[c], server.[c].
794 * Splitted the doc/example_silcd.conf.in. Separated the crypto
795 algorithm parts and created new file silcalgs.conf, that
796 is now included from the example_silcd.conf.in.
798 * Optimized the silc_server_connect_to_router_second to take
799 the connection configuration object from the SilcServerConnection
800 object instead of finding it during the connecting phase.
801 Added the configuration object to SilcServerConnection struct.
802 Affected files silcd/server_internal.h, server.c.
804 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

912 file lib/silcutil/silclog.c.
914 * Fixed the channel message payload decryption in the function
915 silc_channel_message_payload_decrypt to not modify the original
916 buffer before it is verified that the message decrypted
917 correctly. Otherwise, next time it is called with correct
918 channel key it won't encrypt since the payload is corrupted.
919 Affected file lib/silccore/silcchannel.c.
921 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

964 users list to SilcHashTable. The affected files are
965 lib/silcclient/idlist.[ch].
967 * Fixed a bug in hash table tarversing. While the hash table
968 is traversed with SilcHashTableList the table must not be
969 rehashed. It is now guaranteed that auto rehashable tables
970 are not rehashed while tarversing the list. Also defined that
971 silc_hash_table_rehash must not be called while tarversing
972 the table. Added function silc_hash_table_list_reset that must
973 be called after the tarversing is over. The affected files are
974 lib/silcutil/silchashtable.[ch].
976 * Changed all hash table traversing to call the new
977 silc_hash_table_list_reset in server and in client library.
979 * Added function silc_client_on_channel to return the
980 SilcChannelUser entry if the specified client entry is joined

991 lists correctly. Affected file silcd/command.c.
993 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
995 * When sending JOIN command to router for processing the
996 sender's old command identifier was not saved back to the
997 sender's command context, fixed now. The affected file is
1000 * Create the key in JOIN command of the router did not return
1001 the channel key, added check for this. Affected file is
1004 * Fixed a channel ID update bug in JOIN command reply. Do
1005 not directly upgrade the ID but call the function
1006 silc_idlist_replace_channel_id if the ID was changed.
1007 Affected file silcd/command_reply.c.
1009 * Fixed memory leaks from command calling if it would fail.
1010 Affected file silcd/command.c.

1037 functions. Affected file silcd/server.c.
1039 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1040 which ID was changed. This way the router will send the
1041 user list for the channel again, and server won't be in
1042 desync in some rare circumstances. Affected file is
1043 silcd/packet_receive.c.
1045 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1077 not to save the history information for clients. Same was
1078 fixed earlier in remove_clients_by_server function, but not
1079 here. Affected file silcd/packet_receive.c.
1081 * Raised the default connection-retry count from 4 to 7 in
1082 server. Affected file silcd/server.h.
1084 * Cancel any possible reconnect timeouts when we start the
1085 key exchange. Affected file silcd/server.c.
1087 * Do not reconnect on connection failure when SCONNECT was
1088 given. Affected files silcd/server.[ch].
1090 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1092 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1094 * Fixed the NICK command to always give the unformatted
1095 nickname to the one giving the NICK command. If unformatted
1096 nickname is cached already it will be formatted and the
1097 local entry will always get the unformatted nickname.
1098 Affected file lib/silcclient/idlist.c.
1100 * Fixed some double frees from client library commands.
1101 Affected file is lib/silcclient/command.c.
1103 * Fixed CUMODE command in server to assure that no one can
1104 change founder's mode than the founder itself, there was a
1105 little bug. Affected file silcd/command.c.
1107 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1109 * Removed the SilcClientCommandDestructor from the client
1110 libary, it is not needed anymore. Affected files are
1111 lib/silcclient/silcapi.h, command[_reply].[ch],
1112 client_notify, idlist.c.
1114 * Fixed GETKEY command to first resolve client, and then
1115 resolve the server only if the client was not found, instead
1116 of resolving both at the same time. Affected file is
1117 lib/silcclient/command.c.
1119 * Added silc_client_start_key_exchange_cb and lookup the
1120 remote hostname and IP address before starting the key
1121 exchange with server. The affected file is
1122 lib/silcclient/client.c.
1124 * The server's public key is now saved using the IP address
1125 of the server and not the servername for the filename.
1126 The hostname public key filename is checked as an fall back
1127 method if the IP address based filename is not found.
1129 Fixed the GETKEY command to save the fetched server key
1130 in correct filename.
1132 Print the remote server's hostname now when new key is
1133 received during connection process. Affected file is
1134 irssi/src/silc/core/client_ops.c.
1136 * Return always our own public key to the client if it asks
1137 for it with GETKEY command. Affected file silcd/command.c.
1139 * Removed the use_auto_addr variable from default config
1140 file since it was in wrong section. Affected file is
1143 * Fixed TOPIC_CHANGE notification to not route it when it
1144 was sent using silc_server_send_notify_to_channel function.
1145 Affected file silcd/command.c.
1147 * Fixed silc_server_send_notify_kicked to send the kicker's
1148 Client ID also, it was missing. Affected files are
1149 silcd/command.c, silcd/packet_send.[ch].
1151 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1153 * Do not save client history information in SERVER_SIGNOFF.
1154 Fixes the bug in normal server that it does not detect
1155 the client becoming valid after the server becomes back
1156 online. Affected file silcd/server_util.c.
1158 * Added `sock_error' field into the SilcSocketConnection
1159 context. When error occurs during socket operation (read
1160 or write) the error is saved. Added also new function
1161 silc_socket_get_error to return human readable socket error
1162 message. Affected files are lib/silcutil/silcsockconn.[ch],
1163 lib/silcutil/unix/silcunixsockconn.c, and
1164 lib/silcutil/win32/silcwin32sockconn.c.
1166 * The server now prints the socket error message in the
1167 signoff for client. Affected file silcd/server.c.
1169 * Fixed the `created' channel information sending from router
1170 to server in JOIN command. Checks now whether the channel
1171 really was created or not and set it according that.
1173 Fixed the JOIN command to use the client entry's current
1174 ID during the joining procedure instead of the one it sent
1175 in the command (it is checked though), since it can change
1176 between the packet processing and command processing, and
1177 would just case unnecessary pain in the client end. Affected
1178 file silcd/command.c.
1180 * Fixed a channel key payload sending to use correct channel
1181 ID when the server was forced to change the channel's ID by
1182 router. Router sent the key payload with the old Channel ID.
1183 Affected file silcd/packet_receive.c.
1185 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1187 * Call silc_server_save_channel_key only if the key payload
1188 was provided in the JOIN command's command reply. Affected
1189 file silcd/command_reply.c.
1191 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1193 * Fixed silc_mp_sizeinbase to return the value correctly with
1194 MPI. Affected file lib/silcmath/mp_mpi.c.
1196 * Fixed the stop_server signal to correctly stop the scheduler
1197 and gracefully stop the server when SIGTERM or SIGINT signals
1198 are received. Affected file silcd/silcd.c.
1200 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1202 * Simple handling of TERM and HUP signals. Also added some log
1203 flushing call around. Affected file is
1206 * Fixed small bugs in silclog.c. Now buffering output will take
1207 effect after 10 seconds since startup: This will ensure that
1208 no important startup messages are lost. Also output redirection
1209 will preserve original format ([Date] [Type] message).
1210 Affected file is lib/silcutil/silclog.c.
1212 * Added two options to the config file, in the logging section:
1213 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1214 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1216 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1218 * Do not print the warning about log files not being initialized
1219 more than once to avoid excess logging. Affected file is
1220 lib/silcutil/silclog.c.
1222 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1223 the SIM copying in make install in Makefile.am.pre.
1225 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1227 * Rewritten silclog APIs. Globally interesting changes follows:
1228 silc_log_set_files() changed to silc_log_set_file().
1229 silc_log_set_callbacks() changed to silc_log_set_callback().
1230 ROBOdoc documented silclog header file.
1231 SilcLogCb now returns bool to wether inihibit the default
1232 handler or not (to keep the old behaviour return always TRUE).
1233 The new APIs should also fix the problem of the
1234 silcd_error.log file that was written in the current directory.
1237 Log files streams will remain opened after silc_log_set_file()
1238 call, means less CPU usage notably on high traffic servers.
1239 File streams are now full buffered, and flushed to the disk
1240 every 5 minutes, lesses HD activity and CPU usage.
1241 Messages can be redirected, allowing admins to configure
1242 one single logfile for all server messages.
1243 the silc_log_quick global variable to activate fast-logging.
1244 Affected files lib/silcutil/silclog.[ch]
1246 * Changed some code to conform new silclog APIs. Affected
1247 files are doc/example_silcd.conf.in, silcd/server.c
1248 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1251 * Fixed a memory leak that could occur in some situations.
1252 Affected file silcd/serverconfig.c.
1254 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1256 * Added the silc_client_del_client to remove the client from
1257 all channels as well. Affected file lib/silcclient/idlist.c.
1259 * Fixed the client library to correctly remove the client
1260 from all channels when the client entry is being destroyed.
1261 Affected file lib/silcclient/client_notify.c, command.c.
1263 * Added auto-nicking support to the client library. If the
1264 applicatio now sets client->nickname it will be sent to the
1265 server after connecting by the library. This way for example
1266 SILCNICK (or IRCNICK) environment variables will have effect
1267 and always change the nickname automatically to whatever
1268 it is wanted. Affected file lib/silcclient/client.[ch].
1270 * Renamed silc_server_command_bad_chars to the
1271 silc_server_name_bad_chars and moved it to the
1272 silcd/server_util.[ch]. Added also new function
1273 silc_server_name_modify_bad to return nickname that
1274 includes bad characters as new nickname without those
1275 bad characters. This check and modify is now used in
1276 silc_server_new_client when the username is initially set
1277 as nickname, so it must be checked to be valid nickname.
1278 Affected file silcd/packet_receive.c.
1280 * The nickname length is now taken from the packet for real
1281 and not trusted to strlen() since it clearly can return
1282 wrong length for nickname including bad characters. This
1283 also applies to channel names. Affected file silcd/command.c.
1285 * Removed the lib/silcsilm/modules directory. Modules are now
1286 compiled into the lib/silcsim. Fixed the copying of the
1287 modules to follow symbolic links in Makefile.am.pre.
1289 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1291 * Fixed silc_string_regexify list creation. Fixes bugs with
1292 BAN and INVITE commands in server. The affected file is
1293 lib/silcutil/unix/silcunixutil.c.
1295 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1297 * Removed the command destructor entirely from the server's
1298 command and command reply routines. It is not needed, and
1299 its usage was buggy and caused crashes. Affected files are
1300 silcd/command[_reply].[ch].
1302 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Cancel protocol and NULL sock->protocol if timeout
1305 occurred during protocol. Affected file silcd/server.c.
1307 * Cancel protocol timeouts always before calling the final
1308 callback, to assure that after final callback is called
1309 no other state will be called for the protocol anymore.
1310 Affected file silcd/protocol.c.
1312 * Print error log if incoming connection configuration could
1313 not be found. Affected file silcd/server.c.
1315 * Fixed JOIN command to correctly save the founder mode
1316 to the client on normal SILC server, when the channel
1317 was created by the router. Affected file silcd/command.c.
1319 * Fixed LIST command (hopefully) to send correct reply
1320 packets. Affected file silcd/command.c.
1322 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1324 * The silc_packet_receive_process now returns FALSE if the
1325 read data was invalid packet, and TRUE if it was ok.
1327 The server now checks that if unauthenticated connection
1328 sends data and its processing fails the server will close
1329 the connection since it could be a malicious flooder.
1331 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1333 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Make sure the warning about error opening a log file is
1336 printed only once and not everytime it fails (produces
1337 too much useless log). Affected file lib/silcutil/silclog.c.
1339 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1341 * Made the silc_server_daemonise() function more readable.
1342 Affected file silcd/server.c.
1344 * Pid file is now optional, the user may comment it out from
1345 the config file. Removed define SILC_SERVER_PID_FILE, we
1346 don't need a default any longer. Affected file
1347 configure.in.pre, lib/Makefile.am.pre.
1349 * Make some use of the pid file. The server now dies at startup
1350 if it detects a valid pid file on his path. The server would
1351 die anyway in this circumstance, because of the bind() failure.
1352 Affected file silcd/silcd.c.
1354 * No longer compiling lib/dotconf.
1356 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed JOIN command parsing not to crash. Affected file
1359 lib/silcclient/command.c.
1361 * Fied the NICK_CHANGE notify to add the new client entry
1362 even it is resolved. This removes an <[unknown]> nick
1363 thingy bug in the client. Affected file is
1364 lib/silcclient/client_notify.c.
1366 * Do not try to allocate 0 bytes (efence does not like it)
1367 in lib/silccore/silccomand.c when encoding payload.
1369 * Do not take IRCNICK as nickname in Irssi SILC client since
1370 it is not possible to set nickname before hand connecting
1371 the server (TODO has an entry about adding auto-nicking
1374 * Changed the silc_server_command_pending to check whether
1375 there already exists an pending entry with the specified
1376 command, command identifier and pending callback. This is
1377 to fix IDENTIFY and WHOIS related crashes that may register
1378 multiple pending commands with same identifier. Affected
1379 file silcd/command.c.
1381 * Fixed the server to reconnect to the router even if it
1382 was already reconnecting and EOF was received. This to
1383 fix a possibility that the server wouldn't ever try to
1384 auto-reconnect to the router. Affected file silcd/server.c.
1386 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Fixed the server's password authentication to use the
1389 length of the locally saved password, and not the one
1390 sent in the packet. Affected file silcd/protocol.c.
1392 * Fixed same password authentication problem in the
1393 Authentication Payload handling routines in
1394 lib/silccore/silcauth.c.
1396 * Yet another password authentication problem fixed with
1397 channel password handling in silcd/command.c.
1399 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * If first character of string in silc_parse_userfqdn is '@'
1402 then do not parse it. Affected file is
1403 lib/silcutil/silcutil.c.
1405 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Fixed minor bug in IDENTIFY command reply sending, which
1408 caused various weird problems during JOIN when it was
1409 resolving names for users. Affected file silcd/command.c.
1411 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Fixed the IDENTIFY command reply sending to chech better valid
1414 clients. It was possible to send incomplete list of replies.
1415 Affected file silcd/command.c.
1417 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Added silc_client_command[s]_[un]register functions now to
1420 dynamically register the commands in client library. Removed
1421 the static table of commands. This allows the client library
1422 to call commands without causing the application to know about
1423 what commands library has called.
1425 Removed the INFO command reply kludge to detect when the command
1426 was called by library. Now library use its own command reply
1427 function for INFO command.
1429 Added function silc_client_command_call to call a command.
1430 Application can use it to call command, not access the structure
1433 Now all commands that are sent by the client library (not
1434 explicitly sent by application) use own command reply functions.
1436 Affected files around lib/silcclient/ and in
1437 irssi/src/silc/core/.
1439 * Fixed the WHOIS command reply sending to chech better valid
1440 clients. It was possible to send incomplete list of replies.
1442 Fixed the WHOIS and IDENTIFY to send the request to router
1443 if normal server did not do it and did not find any results.
1445 Affected file silcd/command.c.
1447 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Moved the internal data from SilcClient context into its
1450 own file, not accesible to application. Affected files
1451 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1452 and other files in client library.
1454 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Added doc/examples installation target in Makefile.am.pre.
1459 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1462 commands the found client entry will be removed from the
1463 cache, after notifying application about the error. Affected
1464 file lib/silcclient/command_reply.c.
1466 * Changed the /MSG to check for exact nickname user gave, and
1467 not let `nick' match `nick@host' if it is only one found. Now,
1468 user must type the exact nickname (like nick@host2) even if
1469 there are no more than one same nicks found. This is to avoid
1470 a possibility of sending nickname to wrong nickname since
1471 `nick' could match `nick@host'. Affected file is
1472 irssi/src/core/silc-servers.c.
1474 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Do not print "you are now server operator" or similar when
1477 giving /away command. Affected files are
1478 irssi/src/silc/core/client_ops.c, silc-servers.h.
1480 * Made the silc_server_command_pending_error_check to send
1481 the same command reply payload it received back to the
1482 original sender of the command. This way all arguments
1483 that was received by the server will be received by the
1484 client too. Affected file silcd/command.c.
1486 * Added the silc_idcache_add to return the created cache entry
1487 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1489 * Add global clients to expire if they are not on any channel.
1490 This is because normal server will never know if they signoff
1491 if they are not on any channel. The cache expiry will take
1492 case of these entries. This is done by normal servers only.
1493 The affected files are silcd/command_reply.c,
1494 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1496 * If server receives invalid ID notification for WHOIS or
1497 IDENTIFY and the ID exists in the lists, it is removed.
1498 Affected file silcd/command_reply.c.
1500 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1501 in client then client entry that it matches is searched and
1502 the nickname is printed on the screen for user. Affected
1503 file irssi/src/silc/core/client_ops.c.
1505 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Use cache entry expire time in the LIST command reply to
1508 purge old entries from the cache after the LIST command
1509 reply has been received. This way we don't have non-existent
1510 entries in the cache for too long. Affected file is
1511 silcd/command_reply.c.
1513 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * If we are normal server, and we've not resolved client info
1516 in WHOIS or IDENTIFY from router, and it is global client,
1517 we'll check whether it is on some channel. If it is not
1518 then we cannot be sure about its validity and will resolve it
1519 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1520 file silcd/command.c.
1522 * Search channel by name (if possible) rather than by ID
1523 in IDENTIFY command's command reply. Affected file is
1524 silcd/command_reply.c.
1526 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1529 Updated specs and implemented it. Affected file silcd/command.c,
1530 silcd/packet_send.c and silcd/packet_receive.c.
1532 * Implemented the <founder auth> payload handling in the JOIN
1533 command. If provided all conditions for channel joining
1534 except requirement to provide correct passphrase can be
1535 overrided by the channel founder. Updated the protocol specs.
1536 Affected file silcd/command.c.
1538 Added support for founder auth in JOIN command in client
1539 library. Fixed the parsing of the JOIN command now to support
1540 all options as they should be. The affected file is
1541 lib/silcclient/command.c.
1543 * Optimized the WHOIS and IDENTIFY commands to send the request
1544 to router only if it includes nicknames or other names. If
1545 they include only IDs then check the local cache first before
1546 routing. Affected file is silcd/command.c.
1548 * Added channels topic announcements. Affected file is
1549 silcd/packet_receive.c and silcd/server.c.
1551 * Fixed the silc_server_send_notify_topic_set to really destine
1552 the packet to channel. Affected file silcd/packet_send.c.
1554 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1555 library. Affected file lib/silcclient/client_notify.c.
1557 * Added UMODE announcements. Affected file silcd/server.c.
1559 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Memory leak fixes in:
1563 lib/silcutil/silcsockconn.c
1564 lib/silcske/silcske.c
1565 lib/silcske/groups.c
1567 lib/silccrypt/silcpkcs.c
1568 lib/silccore/silccommand.c
1569 lib/silccore/silcidcache.c
1574 * ROBOdoc documented the lib/silcske/groups.h file and a
1575 bit changed the interface for better.
1577 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1579 * Update the client entry context in the ID cache after
1580 nick change. Affected file lib/silcclient/command.c.
1581 Fixes the CUMODE command when regaining founder privileges,
1582 and a little WHOIS problem.
1584 * Fixed silc_net_gethostbyname to correctly call the
1585 inet_ntop. Affected file lib/silcutil/silcnet.c.
1587 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1589 * Added IPv6 support checking to the configure.in.pre, added
1590 also --enable-ipv6 option to override the check. Affected
1591 file configure.in.pre.
1593 * The silc_thread_create now calls the start function
1594 directly if threads support is not compiled in. Removes
1595 ugly #ifdef's from generic code. Affected files are
1596 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1598 * Added silc_net_gethostby[name/addr]_async to asynchronously
1599 resolve. Affected files are lib/silcutil/silcnet.[ch].
1601 * Added support for rendering IPv6 based server, client and
1602 channel IDs. Affected file lib/silcutil/silcutil.c.

1607 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1609 * Added silc_net_gethostby[addr/name] into the
1610 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1611 routines. Added silc_net_is_ip[4/6]. Affected file is
1612 lib/silcutil/unix/silcunixnet.c. All routines that take
1613 address as argument now supports both IPv4 and IPv6 addresses.
1615 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1617 * Fixed LIST command reply sending in server. Affected file
1620 * Server now sends the kicker's client ID in the KICK notify
1621 to the kicked client. Affected file silcd/command.c.
1623 * The client library now parses the kickers client ID and
1624 UI displays it. Affected files lib/silcclient/client_notify.c
1625 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1627 * Made all payload parsing function prototypes consistent.
1628 They all take now const unsigned char * and uint32 pair as
1629 the payload data instead of SilcBuffer. Changes all around
1630 the source tree. Other unsigned char* -> const unsigned char*
1631 changes around the tree as well.
1633 * Optimized SFTP client and server packet sending not to
1634 allocate new buffer for each packet but to recycle the
1635 first allocated buffer. Affected files are
1636 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1638 * Optimized the SFTP client to use SilcList instead of
1639 SilcDList for requests, because it is faster. Affected file
1640 is lib/silcsftp/sftp_client.c.
1642 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1643 into lib/silccore/silcid.[ch].
1645 Renamed silcpayload.[ch] into silcargument.[ch].
1647 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * If client entry is deleted with active key agreement
1650 session, abort the session.
1652 The silc_client_abort_key_agreement now calls the completion
1653 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1655 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1658 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * Don't use __restrict in older GCC's. Affected file is
1661 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1663 * silc_net_localhost now attempts to reverse lookup the
1664 IP/hostname. Affected file lib/silcutil/silcnet.c.
1666 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1667 command. It can be used to gain founder privileges at
1668 the same time when joining the channel.
1670 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1671 kicker's client ID as well. Updated protocol specs.
1673 Defined that the server must send SILC_COMMAND_IDENTIFY
1674 command reply with error status to client who sent
1675 private message with invalid client ID.
1677 Updated the protocol specification.
1679 * Added silc_server_send_command_reply to send any
1680 command reply. Affected file silcd/packet_send.[ch].
1682 * Added silc_id_payload_encode_data to encode ID payload
1683 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1685 * The server now send IDENTIFY command reply with error
1686 status if client ID in private message is invalid. Affected
1687 file silcd/packet_receive.c.
1689 * Save the server key file with server's IP address in
1690 the filename instead of hostname. The affected file is
1691 irssi/src/silc/core/client_ops.c.
1693 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1698 * Added libtool support for compiling shared objects in
1699 lib/silcsim. Affected file configure.in.pre and
1700 lib/silcsim/Makefile.am. Original patch by cras.
1702 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Pid file configuration, and server's config file fixes
1705 patch by toma. Updated CREDITS file.
1707 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Fixed silc_client_channel_message to not try to decrypt
1710 the message twice if it resolved the destination client
1711 information. This could cause of dropping one channel
1712 message. Affected file lib/silcclient/client_channel.c.
1714 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1717 lib/silcclient/client.c. This function is used when the SILC
1718 Client is run under some other scheduler, or event loop or
1719 main loop. On GUI applications, for example this may be
1720 desired to used to run the client under the GUI application's
1721 main loop. Typically the GUI application would register an
1722 idle task that calls this function multiple times in a second
1723 to quickly process the SILC specific data.
1725 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1727 * Fixed silc_server_drop() for dropping the supplementary
1728 groups as well, this could cause a security hole on some
1731 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1736 * Write PID file after dropping privileges. Added -F option
1737 to run server on foreground. A patch by debolaz.
1738 Affected files silcd/server.c, silcd/silcd.c.
1740 * Fixed MOTD to return the MOTD file server name. Affected
1741 file silcd/command.c.
1743 * Added INFO command reply handling to the Irssi SILC Client.
1744 Affected file irssi/src/silc/core/client_ops.c.
1746 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Fixed the silc_idcache_list_* routines to really support
1749 the dynamic list. Fixes a crash. Affected file is
1750 lib/silccore/silcidcache.c.
1752 * Fixed the LIST command reply to really call LIST command's
1753 pending callbacks. Affected file silcd/command_reply.c.
1755 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * Update conn->local_entry->nickname after giving NICK
1758 command. Affected file lib/silcclient/command.c.
1760 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1762 * Added the [pid] option to the silcd configuration file
1764 Affected files: serverconfig.[ch] and silcd.c
1766 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Save fingerprint in WHOIS command reply in server.
1769 Affected file silcd/command_reply.c.
1771 * Fixed NICK commands pending callback registration.
1772 Affected file lib/silcclient/command.c.
1774 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Use ++server->cmd_ident when sending commands in server,
1777 instead of random number. Affected file silcd/command.c.
1779 * Fixed GETKEY command reply to call actually GETKEY pending
1780 command callbacks. Affected file silcd/command_reply.c.
1782 * A bit stricter check for nicknames. Check for same nickname
1783 in NICK command also. Affected file silcd/command.c.
1785 * Do not call INFO command everytime client ID changes, only
1786 during first connecting. Affected file lib/silcclient/client.c.
1788 * Set the new nickname only after successful command reply for
1789 NICK command is returned by server. Affected file
1790 lib/silcclient/command.c.
1792 * Remove nicknames from nicklist during server_signoff notify.
1793 Should fix /NAMES bit more. The affected file is
1794 irssi/src/silc/core/silc-channels.c.
1796 * Added `fingerprint' field to the SilcIDListData in the
1797 silcd/idlist.h to hold the fingerprint of the client's
1800 Send the fingerprint of the client's public key in WHOIS
1803 Affected files silcd/command.c, and silcd/idlist.[ch].
1805 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1806 create fingerprint from given data.
1808 * Show the fingerprint of the client's public key in WHOIS.
1809 Affected files irssi/src/module-formats.[ch] and
1810 irssi/src/silc/core/client_ops.c.
1812 * Format the multiple same nicknames also during JOIN and
1813 NICK_CHANGE notifys. Affected file is
1814 lib/silcclient/client_notify.c.
1816 * Do not print error on screen for invalid private message
1817 payload since it can come if someone is sending private
1818 messages with wrong key. Affected file
1819 lib/silccore/silcprivate.c.
1821 * Fixed multiple concurrent /PING crash. Affected file
1822 lib/silcclient/command.c.
1824 * Changed the wrong ID encoding. All IP addresses must be
1825 in MSB first order in encoded format. They were encoded
1826 wrong and was in LSB format. Affected files are
1827 silcd/serverid.c, lib/silcutil/silcutil.c.
1829 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1831 * Call the `connect' client operation through the scheduler
1832 in case of error. Affected file lib/silcclient/client.c.
1834 * Call the `failure' client operation even if the error
1835 occurred locally during a protocol. Affected file is
1836 lib/silcclient/protocol.c.
1838 * Added support of sending LIST command to router from normal
1839 server. This way normal server can get list of all channels
1840 in the network too. Fixed the channel list sending in the
1841 server too. Affected files are silcd/command.c, and
1842 silcd/command_reply.[ch].
1844 * Added silc_server_update_channels_by_server and
1845 silc_server_remove_channels_by_server. They are used during
1846 disconnection of primary router and in backup router protocol.
1847 Affected file silcd/server_util.[ch], silcd/server.c and
1848 silcd/server_backup.c.
1850 * Fixed channel adding to global list in IDENTIFY command
1851 reply in server. Affected file silcd/command_reply.c.
1853 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1855 * If the incoming packet type is REKEY or REKEY_DONE process
1856 that packet always synchronously. Fixes yet another MAC
1857 failed error on slow (dialup) connections. Affected file
1858 lib/silcclient/client.c and silcd/server.c.
1860 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Call check_version SKE callback for initiator too. Affected
1863 file lib/silcske/silcske.c.
1865 * Implemented fix for security hole found in the SKE that was
1866 fixed in the specification few days back; the initiator's
1867 public key is now added to the HASH value computation.
1868 Added backwards support for the old way of doing it too, for
1869 old clients and old servers. Affected file is
1870 lib/silcske/silcske.c.
1872 * Enabled mutual authentication by default in SKE. If initiator
1873 is not providing mutual authentication the responder will
1874 force it. This will provide the proof of posession of the
1875 private key for responder. The affected files are
1876 lib/silcclient/protocol.c and silcd/protocol.c.
1878 * Do not cache anymore the server's public key during SKE.
1879 We do mutual authentication so the proof of posession of
1880 private key is done, and if the server is authenticated in
1881 conn auth protocol with public key we must have the public
1882 key already. Affected file silcd/protocol.c.
1884 * Added new global debug variable: silc_debug_hexdump. If
1885 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1886 file lib/silcutil/silclog.[ch].
1888 * Fixed compilation warning due to char * -> const char *.
1889 Affected files lib/silcutil/silcnet.h, and
1890 lib/silccore/silcauth.[ch].
1892 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Fixed CMODE command when new channel key was created. If
1895 the creation failed the old key was removed. Next time giving
1896 same command would crash the server since the old key was
1897 freed already. Affected file silcd/command.c.
1899 * Fixed the silc_server_announce_get_channels to not crash
1900 on reconnect. Affected file silcd/server.c.
1902 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Added silc_log_set_debug_string function to set a regex
1905 string to match for debug output. Only the function names,
1906 or filenames matching the given debug string is actually
1907 printed. This way it is possible to filter out those debug
1908 strings that user is not interested in.
1910 Fixed a bug in silc_string_regexify.
1912 Affected files lib/silcutil/silclog.[ch], and
1913 lib/silcutil/unix/silcunixutil.c.
1915 * Changed the -d options in both server and Irssi SILC client
1916 to take the debug string as argument. Affected files
1917 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1919 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1921 * Added silc_hash_babbleprint to create a Bubble Babble
1922 Encoded fingerprint. The encoding is developed by Antti
1923 Huima (draft-huima-babble-01.txt), and it creates human
1924 readable strings out of binary data. Affected file
1925 lib/silccrypt/silchash.[ch].
1927 * Print the babble print now in addition of fingerprint as well
1928 in Irssi SILC client. Affected files are
1929 irssi/src/fe-common/silc/module-formats.[ch],
1930 irssi/src/fe-common/silc/core/client_ops.c.
1932 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Fixed a security problem found in SKE. The initiator's
1935 public key too is now added to the HASH hash value creation
1936 which is signed by the responder to create the SIGN value.
1937 This will prevent anyone in the middle to lie to the responder
1938 about the initiator's public key. If this is done now, the
1939 man in the middle will get caught. Updated the protocol
1942 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Better installation directory handling. Configure module
1945 paths and other paths automatically to example_silc* files
1946 in doc/. A patch by toma.
1948 * Fixed compiler warning from MPI library, and from SILC RNG.
1951 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1952 It can be configured with ./configure. A patch by toma.
1954 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Find correct make to use in prepare-clean. A patch by
1957 toma. Affected file prepare-clean.
1959 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1961 * Added irssi variables use_auto_addr, auto_bind_ip,
1962 auto_bind_port and auto_public_ip.
1964 * Changed the interface for silc_client_send_key_agreement
1965 in lib/silcclient/silcapi.h
1969 irssi/src/silc/core/silc-core.c
1971 lib/silcclient/silcapi.h
1972 irssi/src/silc/core/silc-channels.c
1973 lib/silcclient/client_keyagr.c
1976 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Added silc_pkcs_public_key_compare to compare two
1979 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1981 * Check that the client who set the founder mode on the
1982 channel is the same client that is giving the founder
1983 mode to itself. It is done by comparing the saved public
1984 key (it is saved even in the authentication is passphrase).
1985 Affected file silcd/command.c.
1987 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1989 * Do not process packet for disconnected socket connection.
1990 Affected file lib/silccore/silcpacket.c.
1992 * Process the DISCONNECT packet through scheduler in the
1993 client library. Affected file lib/silcclient/client.c.
1995 * Fixed the silc_client_packet_parse to not to increase
1996 the packet sequence number if the conn->sock and the
1997 current socket connection is not same. This can happen
1998 for example during key agreement when the conn includes
1999 multiple socket connections (listeners). Affected file
2000 lib/silcclient/client.c.
2002 * The sender of the file transfer request now provides also
2003 the pointer (listener) for the key exchange protocol. If
2004 the listener cannot be created then it sends empty key
2005 agreement and lets the receiver provide the listener.
2007 Added `local_ip' and `local_port' arguments to the
2008 silc_client_file_send. If they are provided they are used,
2009 if not then it will attempt to find local IP address, if
2010 not found or bind fails then the remote client will provide
2013 Affected files are lib/silcclient/client_ftp.c and
2014 lib/silcclient/silcapi.h.
2016 * Extended the FILE SEND command to support defining the
2017 local IP and port for key exchange listener. They are
2018 optional. Affected file irssi/src/silc/core/silc-servers.c.
2020 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Defined to WHOIS command reply the sending of fingerprint
2023 of the client's public key (if the proof of posession of the
2024 corresponding private key is verified by the server).
2025 Updated to the protocol specification.
2027 * Added support of receiving the client's public key's
2028 fingerprint in command reply in client library. Affected
2029 file is lib/silcclient/command_reply.c, and
2030 lib/silcclient/idlist.[ch].
2032 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Do not send over 128 chars long nickname to the server
2035 in NICK command. Affected file lib/silcclient/command.c.
2037 * Do not send over 256 chars long channel names to the server
2038 in JOIN command. Affected file lib/silcclient/command.c.
2040 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * Assure that silc_server_close_connection cannot be called
2043 twice for same socket context. Affected file is
2046 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Send error message to application if opening file for
2049 writing during file transfer fails. Affected file is
2050 lib/silcclient/client_ftp.c.
2052 Remove all file transfer sessions for a client that we're
2053 removing from ID cache.
2055 Affected file is lib/silcclient/client_ftp.c.
2057 * Fixed silc_net_addr2bin to return correct address. Affected
2058 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2060 * Fixed file transfer session removing on signoff notify.
2061 Affected file irssi/src/silc/core/silc-servers.c.
2063 * Added the SilcClientFileError to be returned in the monitor
2064 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2065 Affected file lib/silcclient/silcapi.h.
2067 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Fixed a crash in silc_client_ftp_free_sessions and
2070 silc_client_ftp_session_free_client. Affected file
2071 lib/silcclient/client_ftp.c.
2073 * Added `disabled' field in the SilcChannelEntry in the server
2074 to indicate if the server entry is disabled. Affected file
2075 silcd/idlist.h, silcd/command[_reply].c.
2077 * SILC server adds now /var/run/silcd.pid everytime it is
2078 started. Affected file silcd/silcd.c.
2080 * Added silc_server_packet_send_clients to send a packet to
2081 the provided table of client entries. Affected file
2082 silcd/packet_send.[ch].
2084 * Fixed a crash in client resolving in client_prvmsg.c in
2085 client library. Affected file lib/silcclient/client_prvmsg.c.
2087 * Do not actually remove the client directly from ID cache
2088 during SERVER_SIGNOFF, but invalidate it. This way we
2089 preserve the WHOWAS info for the client. Affected file
2090 silcd/server_util.c.
2092 * Fixed SERVER_SIGNOFF notify handling in the server. The
2093 server is now able to process incoming SERVER_SIGNOFF notify
2094 for a server that it doesn't even know about. It will remove
2095 the clients provided in the notify. Affected file
2096 silcd/packet_receive.c.
2098 * Check for partial packet in data queue after every packet that
2099 was found from the queue. Return and wait for more data if
2100 there is partial data in queue. Affected file is
2101 lib/silccore/silcpacket.c.
2103 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Added SilcClietFileError enum to indicate error in
2106 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2107 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2108 Affected files lib/silcclient/silcapi.h and
2109 lib/silcclient/client_ftp.c.
2111 * Check that newsize in silc_buffer_realloc is larger than
2112 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2114 * Added better monitor of file transfers. It now monitors
2115 key agreement protocol during the file transfer too. Added
2116 error reporting too. Affected files
2117 irssi/src/silc/core/silc-servers.c,
2118 irssi/src/fe-common/silc/module-formats.[ch].
2120 * Wrote a help file for FILE command.
2122 * Added silc_rng_global_get_byte_fast to get not-so-secure
2123 random data as fast as possible. Random data is read from
2124 /dev/urandom if available and from the SILC RNG if not
2125 available. It is used in padding generation. Affected file
2126 lib/silccrypt/silcrng.[ch].
2128 * All packets in client library are now processed synchronously.
2129 Optimized packet processing a lot. Affected file
2130 lib/silcclient/client.c.
2132 * All server connection packets are processing synchronously
2133 now in server, to optimize packet processing. Affected file
2136 * Include files are installed now only in Toolkit distribution
2137 if make install is given. Affected files: all Makefile.am's.

2141 * Assure that silc_client_notify_by_server_resolve does not
2142 resolve the client information multiple times. If it cannot
2143 be found by the first it cannot be found at all. Affected
2144 file lib/silcclient/client_notify.c.
2146 * Fixed WHOWAS command reply calling. Affected file
2147 lib/silcclient/command_reply.c.
2149 * Removed all references to silc_idlist_get_client from the
2150 Irssi SILC client since that call is internal call used by
2151 the library. The Irssi SILC client will use now client
2152 retrieval functions found in silcapi.h.
2154 * Fixed a bug in resolving nickname info before sending
2155 private message. It used freed memory. Affected file
2156 irssi/src/silc/core/silc-servers.c.
2158 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Assure my_channels statistics cannot go negative in server.
2161 Affected files silcd/server.c, silcd/server_util.c.
2163 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2177 * Added silc_net_localip to return local host's IP address.
2178 Affected file lib/silcutil/silcnet.[ch].
2180 * If key exchange or rekey protocol is active for a connection
2181 parse all packets syncronously since there might be packets
2182 in packet queue that we are not able to process without first
2183 processing packets before them. Affected file silcd/server,
2184 lib/silcclient/client.c.
2186 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2187 whether library should continue processing the packet.
2188 Affected file lib/silccore/silcpacket.h.
2190 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2219 lib/silcutil/silcutil.[ch].
2221 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2223 * Resolve the client info when received private message or
2224 channel message for a client which nickname we don't know.
2225 Affected files lib/silcclient/client_prvmsg.c and
2226 lib/silcclient/client_channel.c.
2228 * Do not crash in /KEY if client is not connected. Affected
2229 file irssi/src/silc/core/silc-channels.c.
2231 * Added SilcClientStatus field to the SilcClientEntry in the

2234 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2235 is incomplete and is being resolved, it won't be resolved
2238 Make sure also that USERS command reply does not resolve
2239 twice information. Affected file is
2240 lib/silcclient/command_reply.c.
2242 Make sure that silc_client_get_clients_by_list does not
2243 resolve twice same information.
2245 * Check for valid client->id in the silc_server_free_client_data.
2246 Affected file silcd/server.c.
2248 * Fixed /GETKEY nick@server not to crash if the server entry
2249 is not found. Affected file lib/silcclient/command.c.
2251 * Fixed the silc_server_check_cmode_rights to check the
2252 requested modes correctly. Affected file silcd/command.c.

2256 * Better checks for non-printable chars in nick added.
2257 Affected file silcd/command.c.
2259 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2261 * Call the silc_server_udpate_servers_by_server in the
2262 primary router that comes back online in the backup resuming
2263 protocol. Otherwise it routes packets wrong. Affected file
2264 silcd/server_util.[ch], silcd/server_backup.c.
2266 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2269 lib/silcutil/silcbuffmt.[ch].
2271 * Redefined the SILC packet header to include the padding
2272 length. Affected file lib/silccore/silcpacket.[ch].
2274 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2275 length for maximum padding up to 128 bytes). Affected
2276 file lib/silccore/silcpacket.h.
2278 * Removed all backwards support for old 0.5.x MAC thingies.
2279 The SILC packet header change makes it impossible to be
2280 backwards compatible.
2282 * Send the ENDING packet with timeout in the backup resuming
2283 protocol. This is to assure that all routers has connected
2284 to the primary router. Affected file silcd/server_backup.c.
2286 * Changed the RNG to take the first IV from random data. It
2287 used to take it from zero actually. Changed the RNG also
2288 to use /dev/urandom during session. /dev/random is used
2289 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2291 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Changed the SILC packet header to have the first two bytes
2294 (the packet length) encrypted. Affected files aroung the
2295 code tree, lib/silccore/silcpacket.[ch]. Removed the
2296 SilcPacketCheckDecrypt callback. It is not needed anymore
2297 since the silc_packet_receive_process will determine now
2298 whether the packet is normal or special.
2300 * Implemented the unidirectional MAC keys. Affected files
2301 lib/silcske/silcske.c, silcd/protocol.c and
2302 lib/silcclient/protocol.c.
2304 * Implemented the packet sequence number to the MAC computation.
2305 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2306 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2307 lib/silcclient/protocol.c.
2309 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Allow backup router to announce servers. All servers
2312 announced by backup router are added to the global list
2313 automatically. Update hte server's socket to our primary
2314 router also when backup router announces a server.
2315 Affected file silcd/packet_receive.c.
2317 * Do not update the client->router in the function
2318 silc_server_udpate_clients_by_server if the client is on
2319 global list. We might fail to find any specific server
2320 for locally connected clients and local cell clients. They
2321 should still use the `from' and not `to' as client->router.
2322 This fixes backup router resuming protocol. Affected file
2323 silcd/server_util.c.
2325 * Decrease channel statistics count only if the channel
2326 deletion worked. Affected files are silcd/server.c and
2327 silcd/server_util.c.
2329 * Added silc_server_update_servers_by_server to update origin
2330 of all server entries. Used during backup router protocol.
2331 Affected files silcd/server_util.[ch], silcd/server.c. and
2332 silcd/backup_router.c.
2334 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2335 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2336 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2337 lib/silccrypt/silchmac.c.
2339 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Assure that router cannot reroute the same channel message
2342 to the sender. Affected file silcd/packet_receive.c.
2344 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2346 * Made better checks that the channel message is not sent
2347 to the router it came from. Affected file is
2348 silcd/packet_send.c. Fixed memory leak too.
2350 * Announce informations for incoming router connection, but
2351 only after checking if it is replaced by backup router.
2352 Affected file silcd/packet_receive.c.
2354 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Fixed the backup resuming protocol to work in multiple
2357 router environment. Affected file silcd/server_backup.c.
2359 * Route packet only to one router in the function
2360 silc_server_packet_send_to_channel. Affected file is
2361 silcd/packet_send.c.
2363 * Fixed silc_server_send_notify_dest to set the broadcast
2364 flag. Fixed the silc_server_send_notify_topic to actually
2365 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2366 Affected file silcd/packet_send.c.
2368 * Changed the SFTP Filesystem interface. Changed the
2369 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2370 the filesystem operation function. The SilcSFTPFilesystem
2371 is now a context that is allocated by all filesystem allocation
2372 functions and it already includes the operations structure
2373 and filesystem specific context. It is given as argument
2374 now to the silc_sftp_server_start. This made the interface
2375 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2376 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2378 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Changed the backup router adding and getting interfaces
2381 in the server. The router that will be replaced by the
2382 specified backup router is now sent as argument. Affected
2383 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2386 * Added silc_net_addr2bin_ne to return the binary form of
2387 the IP address in network byte order. Affected files
2388 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2390 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Check for existing server ID in silc_server_new_server
2393 and in silc_server_connect_to_router_final and remove the
2394 old entry if it exists. Affected file silcd/packet_receive.c,
2397 * Send the channel message always to only one router, either
2398 in upstream or downstream. Affected file is
2399 silcd/packet_send.c.
2401 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2403 * Wrote the definition of the backup resuming protocol to the
2404 protocol specification.
2406 * Removed one redundant channel key generation from normal
2407 server during joining procedure. Removed one redundant
2408 channel key sending from server to router during joining
2409 procedure. Affected file silcd/command.c.
2411 * Made minor bugfixes to the backup router resuming protocol.
2412 Affected file silcd/server_backup.c, server.c.

2417 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2420 * Implemented the backup resuming protocol that is used to
2421 resume the primary router position in the cell after the
2422 primary router comes back online. Affected files
2423 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2424 and silcd/server_util.[ch].
2426 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Sleep two (2) seconds after sending QUIT command to server.
2429 Affected file lib/silcclient/command.c.
2431 * Assure that if outgoing data buffer is pending do not force
2432 send any data. Affected file silcd/packet_send.c.
2434 * Assure that if outgoing data buffer is pending do not force
2435 send any data. Affected file lib/silcclient/client.c.
2437 * Implemented the backup router support when the primary router
2438 goes down. The servers and routers can now use the backup
2439 router as new primary router without loosing connectivity.
2441 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2444 in the server to indicate disabled entry. All data read
2445 from the connection will be ignored and no data is sent
2446 for entry that is disabled. Affected files are
2447 silcd/idlist.h, silcd/server.c.
2449 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Created SFTP client and server test programs in the
2452 lib/silcsftp/tests directory.
2454 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Implemented memory filesystem (virtual filesystem) for
2457 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2460 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Implemented the SFTP (SSH File Transfer Protocol) to the
2463 lib/silcsftp. It includes SFTP client and SFTP server
2466 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Moved lib/silccore/silcprotocol.[ch] to the
2469 lib/silcutil library.
2471 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2472 take variable argument list pointer as argument. Affected
2473 file lib/silcutil/silcbuffmt.[ch].
2475 * Added silc_buffer_set function that is used to set data
2476 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2477 Affected file lib/silcutil/silcbuffer.h.
2479 * Changed various routines in the core library to use the new
2480 silc_buffer_set instead of allocating new buffer only for
2483 * Added 64-bit value formatting and unformatting support to the
2484 silc_buffer_[un]format routines. Affected file is
2485 lib/silcutil/silcbuffmt.[ch].
2487 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2488 to includes/bitmove.h.
2490 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Fixed channel user mode saving in client library. Affected
2493 file lib/silcclient/command[_reply].c.
2495 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Defined the file transfer to the SILC Protocol. Added
2498 new packet type SILC_PACKET_FTP and defined File Transfer
2499 Payload. The mandatory file transfer protocol is SFTP
2500 (SSH File Transfer Protocol). Affected file in addition
2501 of the internet draft is lib/silccore/silcpacket.h.
2503 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2504 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2505 is used as part of backup router protocol when the primary
2506 router of the cell is back online and wishes to resume
2507 the position as primary router.
2509 * Redefined the MAC generation keys in the protocol. The
2510 same key is not used anymore in both direction. Both
2511 direction will now use different keys for sending and
2512 receiving. This fixes a potential security flaw. This
2513 change causes incompatibilities in the protocol.
2515 * Redefined also the MAC computation from the packet.
2516 An packet sequence number is now added to the MAC
2517 computation. This prevents possible replay attacks against
2518 the protocol. This change too causes incompatibilities
2521 Added `sequence' field to the SilcPacketContext to hold
2522 the current sequence number for the packet.
2524 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Added `created' field to the SilcIDListData in the file
2527 silcd/idlist.h to indicate the time when the entry was
2530 * Added `created' field to the SilcChannelEntry too. Affected
2531 file silcd/idlist.h.
2533 * Added `creation_time' aguments to all the announcement functions
2534 in the server. If it is provided then only the entries that
2535 was created after the provided time frame are actually
2536 announced. Affected file silcd/server.[ch].
2538 * The protocol says that the Channel ID's IP address must be
2539 based on the router's IP address. Added check for this in
2540 the silc_server_new_channel when processing incoming New Channel
2541 Payload. Affected file silcd/packet_receive.c.
2543 * Print out the correct version with --version in SILC client.
2544 Affected file irssi/src/silc/core/silc-core.c.
2546 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Fixed WHOWAS command to check for completnes of the client
2549 entry always, not just when the command is coming from client.
2550 Affected file silcd/command.c.
2552 * Added new function silc_server_packet_queue_purge to purge the
2553 outgoing data queue to the network. After the function returns
2554 it is guaranteed that the outgoing packet queue is empty.
2555 Affected file silcd/packet_send.[ch].
2557 * Purge the outgoing packet queue in the rekey protocol's final
2558 callback to assure that all rekey packets go to the network
2559 before quitting the protocol. Affected file silcd/server.c.
2561 * Added silc_client_packet_queue_parse as similar function as
2562 in server to the client library. The affected file is
2563 lib/silcclient/client.c.
2565 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Splitted silcd/server.c and created silcd/server_util.[ch]
2568 for utility functions.
2570 * Added new socket flag SILC_SF_DISABLED to indicate that the
2571 connection is open but nothing can be sent to or received from
2572 the connection. Affected file lib/silcutil/silsockconn.[ch].
2573 The checking for disabled socket is checked in the low level
2574 silc_socket_write and silc_socket_read functions.
2576 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Allow only nicknames and channel names that fits into the
2579 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2581 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * When processing JOIN command reply in server check that if
2584 the channel exists in our global list we'll move it the local
2585 list. Affected file silcd/command_reply.c.
2587 * Fixed the check whether client is joined on the channel already
2588 in JOIN command. Affected file lib/silcclient/command.c.
2590 * Fixed the JOIN command reply to check whether the channel
2591 already exists. Affected file lib/silcclient/command_reply.c.
2593 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Added silc_ske_status_string to map the SKE error numbers
2596 to readable strings. The affected files are
2597 lib/silcske/silcske[_status].[ch].
2599 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Do not show the private channels on the WHOIS channel list
2602 as it is not allowed by the protocol. The affected file is
2605 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Assure that the packet length digged from the actual packet
2608 is something sensible in the silc_packet_decrypt_rest_special
2609 in lib/silccrypt/silcpacket.c.
2611 * Free and NULL the allocated pointer in silc_hmac_alloc if
2612 the HMAC allocation fails. The affected file is
2613 lib/silccrypt/silchmac.c.
2615 * Print the selected security properties to the log files in
2616 the server. Affected file silcd/protocol.c.
2618 * Add SKE's reference counter even if calling the completion
2619 callback manually. Otherwise it goes negative, although it
2620 does not cause any problems. The affected file is
2621 lib/silcske/silcske.c.
2623 * Remove the client entry with short timeout after giving the
2624 KILL command. Affected file lib/silcclient/command.c.
2626 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2627 case all found clients are already disconnected (WHOWAS would
2628 found them) in the server. Affected file silcd/command.c.
2630 * Update the last_receive (time of last data received) to be
2631 updated only when received private or channel message so that
2632 the idle time showed in WHOIS makes more sense.
2634 * Added boolean field `valid' in to the SilcClientEntry in the
2635 client library to indicate whether the entry is valid or not.
2636 This fixes the nickname change bug on channel when changing
2637 the nickname to be same than the old (like nick to Nick) the
2638 nickname formatter doesn't set the new nick anymore to Nick@host.
2639 Affected file lib/silcclient/idlist.[ch].
2641 * Now actually fixed the nickname changing on disconnection.
2642 Added new function silc_change_nick to the Irssi SILC Client.
2643 Affected file irssi/src/silc/core/client_ops.c,
2644 irssi/src/silc/core/silc-nicklist.[ch].
2646 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Check that the public key exists in the GETKEY command before
2649 trying to encode it. Affected file silcd/command.c.
2651 * Print some notifications on received public keys with GETKEY
2652 command in the Irssi SILC Client. Affected files are
2653 irssi/src/fe-common/silc/module-formats.[ch],
2654 irssi/src/silc/core/client_ops.c.
2656 * Use IDENTIFY command to resolve the server information in the
2657 GETKEY command instead of INFO command. Affected file
2658 lib/silcclient/command.c.
2660 * All command reply functions in the client library now calls
2661 the pending command reply callbacks even if an error has
2662 occurred. The server has done this a long time and now it was
2663 time to move the client library to this as well. Now all
2664 errors can be delivered back to the pending command reply
2665 callbacks if necessary. Affected files are
2666 lib/silcclient/command[_reply].[ch].
2668 * Change the nickname on disconnection back to the username
2669 because in reconnect the server will enforce it to it anyway.
2670 Affected file irssi/src/silc/core/silc-servers.c.
2672 * Fixed a config file parsing bug in the Irssi SILC client.
2673 Affected file irssi/src/silc/core/clientconfig.c.
2675 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * When printing the channel mode on JOIN, verify that the
2678 channel key and channel's HMAC are valid. Affected file
2679 irssi/src/silc/core/client_ops.c.
2681 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2684 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2685 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2687 * Removed channel key rekey task deleting from the function
2688 silc_server_save_channel_key. Affected file silcd/server.c.
2689 Added explicit timeout task context instead that is used to
2690 delete the task if we are registering a new task before the
2691 new task has elapsed.
2693 * When channel key rekey occurs the client library now saves
2694 the old channel key for a short period of time (10 seconds) and
2695 is able to use it in case some is still sending channel
2696 messages encrypted with the old key after the rekey. Affected
2697 file lib/silcclient/[idlist.h|client_channel.c].
2699 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2701 * Added check to the silc_server_new_id_real to not accept
2702 new ID if it is the sender's own ID. Affected file is
2703 silcd/packet_receive.c.
2705 * Assure that we do not announce ourself or the one we've
2706 sending our announcements when we're router and are announcing
2707 servers to our primary router. Affected file silcd/server.c.
2709 * Fixed silc_server_command_identify_check_client to assemble
2710 correct WHOIS packet. It send corrupted WHOIS packet and
2711 caused problem with router to router connections. Affected
2712 file silcd/command.c.
2714 Fixed also silc_server_command_whois_check the same way
2715 as for the IDENTIFY command.
2717 * Added new SilcIDListStatus to the server in the SilcIDListData
2718 structure. The status now includes the current status of
2719 the entry (like registered, resolved etc.). Affected file
2720 silcd/idlist.[ch]. Defined a bunch of different status types
2721 as well. This replaced the old boolean registered field as well.
2723 Added resolve_cmd_ident field to the SilcClientEntry structure
2724 too so that if the entry is for example being resolved so
2725 another command may attach to the same pending command reply
2726 without requiring to resolve the same entry again. This concept
2727 should optimize the WHOIS and the IDENTIFY resolving under
2728 heavy load by taking away unnecessary resolving for entries
2729 that are being resolved already.
2731 Added support for adding multiple pending commands for one
2732 command idenfier. Affected file silcd/command[_reply].[ch].
2734 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2735 before deleting the data. Otherwise the hash table will have
2736 freed data in comparison functions. Affected file is
2737 silcd/command_reply.c.
2739 * Fixed silc_idlist_replace_client_id to add the new entry to
2740 the cache with NULL nickname. Otherwise there will be invalid
2741 memory as the nickname after the nickname is freed. Affected
2742 file silcd/packet_receive.c.
2744 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2745 saved into wrong slots because the previous number of entries
2746 was not taken into account. Affected file silcd/idlist.c.
2747 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2749 * If we are router and we receive JOIN notify to a channel that
2750 does not have any users then notified client is marked as the
2751 channel founder, as it is it. The affected file is
2752 silcd/packet_receive.c
2754 * Added to the extended hash table API's table_del_*ext functions
2755 the destructor as argument too, so that the caller can decide
2756 which destructor to use or whether to use destructor at all.
2757 Affected file lib/silcutil/silchashtable.[ch].
2759 * Fixed ID Cache purging. It actually deleted the entries from
2760 the hash table after the data was freed. The hash table ended
2761 up comparing freed memory. The affected file is
2762 lib/silccore/silcidcache.c.
2764 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Fixed Irssi SILC client's KILL command's HELP syntax.
2768 * The USERS command now resolves the detailed user information
2769 if the userinfo field is missing. Affected file is
2770 lib/silcclient/command_reply.c.
2772 * Do not print error in silc_file_read if the read file does
2773 not exist. Just silently return NULL. Affected file is
2774 lib/silcutil/silcutil.c.
2776 * Fixed the silc_log_output to not wine about NULL filename
2777 and to not create some bogus " " filename. Affected file is
2778 lib/silcutil/silclog.c.
2780 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Fixed various printing bugs on the user interface in the
2783 Irssi SILC Client. Minor changes that were forgotten from
2786 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Fixed the configure.in.pre and the compilation and distribution
2789 environment to support the new autoconf 2.52. That version is
2790 now required to compile the CVS trunk.
2792 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2795 to generally parse user@fqdn format strings. Affected file
2796 lib/silcutil/silcutil.c.
2798 * Added nickname_format and nickname_force_format fields to the
2799 SilcClientParams structure. The first one defines the format
2800 for the nicknames that the library will enforce if the receives
2801 multiple same nicknames. The second one is boolean value and
2802 can be used to force the library to always enforce the format
2803 to the nicknames regardles whether there are multiple nicknames
2804 or not. This configurable formatting was employed to flexibly
2805 support accessing multiple nicknames from the user interface.
2806 The userinterface can now set the nicknames to what ever format
2807 they prefer. Affected file lib/silcclient/silcapi.h.
2809 Added function silc_client_nickname_format to the file
2810 lib/silcclient/idlist.c. It performs the nickname formatting.
2812 Added new field `hostname´ to the SilcClientEntry context.
2813 It holds the hostname of the client. Affected file is
2814 lib/silcclient/idlist.h.
2816 * Irssi SILC Client sets the nicknames in nick@hostn format.
2817 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2818 irssi/src/silc/core/silc-core.c.
2820 The WHOIS printing now also shows both the real nickname and
2821 the formatted nickname so that user knows how to access the
2822 user if there are multiple same nicknames cached. Affected
2823 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2824 printing formatting too to take the hostname now as a separate
2825 argument. The Affected file is
2826 irssi/src/fe-common/silc/modules-formats.[ch].
2828 * Changed the silc_client_get_clients_local to accept the formatted
2829 nickname as argument. It accepts the real nickname too but the
2830 formatted nickname can be used to find the true entry from
2831 multiple entries. Affected file lib/silcclient/silcapi.h and
2832 lib/silcclient/idlist.c.
2834 * Added nickname_format_parse field to the SilcClientParams.
2835 It is a callback function provided by the application to parse
2836 the nickname out of the formatted nickname string. The library
2837 calls it to get the nickname from the formatted string. Since
2838 the application generally knows better the format of the nickname
2839 string it parses it instead of the library, even though library
2840 encodes the formatted string. If the callback function is not
2841 provided then the library will use the string as is. The
2842 affected file is lib/silcclient/silcapi.h.
2844 * All the nickname strings passed to the client library in
2845 commands are now expected to be formatted nickname strings.
2846 If the command does not support the formatted nickname string
2847 it will assume that the sent string is the actual nickname.
2848 Affected file lib/silcclient/command.c.
2850 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2852 * Added public key authentication support to OPER and SILCOPER
2853 commands in the client library. Affected file is
2854 lib/silcclient/command.c.
2856 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Changed the get_auth_methdod client operation to be asynchronous.
2859 It can be async if the application resolves the authentication
2860 method from the server during the negotiation. Added new
2861 SilcGetAuthMeth completion callback that the application will
2862 call after resolving the authentication method.
2864 Added function silc_client_request_authentication_method that
2865 the application can use to resolve the authentication method
2866 from the server. Added also SilcConnectionAuthRequest callback
2867 that the library will call after the server has replied. The
2868 application can call this function if it does not know the
2869 current authentication method.
2871 Affected files are lib/silcclient/client.c and
2872 lib/silcclient/silcapi.h.
2874 * The Irssi SILC client now automatically resolves the authentication
2875 method incase any configuration information is not present (and
2876 currently there never is). The affected file is
2877 irssi/src/silc/core/client_ops.c.
2879 * Fixed public key authentication from the client library.
2880 Affected file lib/silcclient/protocol.c. Changed also the
2881 protocol specification about the public key authentication in
2882 the connection authentication protocol. The actual data to be
2883 signed is now computed with a hash function before signing.
2885 * Fixed the public key authentication from the server as well.
2886 Affected file silcd/protocol.c.
2888 * Removed the mlock()'s from the memory allocation routines.
2889 Affected file lib/silcutil/silcmemory.c. The ./configure does
2890 not check anymore for the mlock(). Affected file is
2893 * Fixed USERS command in server to allow the execution of the
2894 command for private and secret channels if the client sending
2895 the command is on the channel. Affected file silcd/command.c.
2897 * Fixed silc_client_get_clients_local to return the clients
2898 count correctly. It could return wrong value. Affected file
2899 lib/silcclient/idlist.c.
2901 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2904 types. The assembler optimizations seemed not to like 64-bit
2905 data types. The assmebler optimizations thus are now enabled
2906 also for BSD systems as opposed to only enable them for Linux.
2908 * Do not check for threads at all on BSD systems. Affected
2909 file configure.in.pre.
2911 * Removed -n and -h options from the Irssi SILC Client since
2912 they are not used in silc.
2914 * Fixed the prime generation to assure that the first digit
2915 of the generated random number is not zero since our conversion
2916 routines does not like number strings that starts with zero
2917 digit. If zero digit is seen the random number is regenerated.
2918 This caused some corrupted RSA keys when the zero first digit
2919 was met. Affected file lib/silcmath/silcprimegen.c.
2921 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Fixed WIN32 configuration in the ./configure script.
2924 Fixed to include xti.h on environments that has it.
2925 Patches by Carsten Ilchmann and andrew.
2927 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Changed the silc_id_create_client_id to be collision
2930 resistant. It is now assured that there cannot be created
2931 two same client ID's. I suspect that some weird bugs in
2932 the server were actually caused by duplicate Client IDs.
2933 Affected file silcd/serverid.[ch]. A router receiving
2934 new ID now also assures and informs the sending server
2935 if the ID caused collision.
2937 * Changed the silc_id_create_channel_id to also assure that
2938 there are no collisions.
2940 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Statement about ignoring the Mutual Authentication flag when
2943 performing rekey with PFS was a bit misleading. It is ignored
2944 if it was set in the initial negotiation, it cannot be even
2945 set in the rekey. Fixed in the ke-auth draft. Started the
2946 new versions of the protocol drafts in the doc/.
2948 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Fixed a bug in silc_client_command_identify_save when saving
2951 new channel information. The channel name was no duplicated
2952 and caused crash on exit. Affected file is
2953 lib/silcclient/command_reply.c.
2955 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Fixed the getkey command handling in the server. Send just
2958 empty OK reply to the sender if the key could not be fetched
2959 (but everything else was ok, like the key just was not available).
2960 Changed the public key parameter to optional in the protocol
2961 specs so that empty OK reply can be sent. Affected file
2964 Added a message to Irssi SILC client to tell to user if the
2965 server did not return a public key.
2967 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Fixed a channel key regeneration bug. It registered new
2970 timeout tasks exponentially until all system resources were
2971 used. Affected file silcd/server.c.
2973 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Added the SILC Document generator to the scripts/silcdoc.
2976 It can be used to generate the Toolkit Reference Manual out
2977 of the source tree. Internally it will also use the RoboDoc
2978 generator now imported in util/robodoc.
2980 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2982 * Added couple of return's in rekey protocol if error orccurred
2983 during the protocol. The execution must be terminated.
2984 Affected file silcd/protocol.c. Also, terminate the protocol
2985 always with timeout.
2987 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * The client's Client ID was created initally from the wrong
2990 nickname (it could have been in format nick@host) in the
2991 silc_server_new_client. Affected file silcd/packet_receive.c
2993 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Added some SILC_LOG_ERROR's to various error conditions
2996 if client could not be added to ID cache. Affected files
2997 silcd/packet_receive.c and silcd/server.c.
2999 * When client's sock->user_data is freed, NULL also the
3000 client->router and client->connection pointers. Added check
3001 for these pointers being NULL to various places around the
3002 code. Affected file silcd/server.c.
3004 * Added client->data.registered == TRUE checks to various
3005 places around the code to assure that unregistered client's
3006 are not handled when it is not allowed. Affected file
3009 * Added `bool registered' fields to all
3010 silc_idlist_[server|client]_get_* routines to indicate whether
3011 the fetched client needs to be registered or not. Affected
3012 file silcd/idlist.[ch].
3014 * Add your own entry as registered to the ID cache in the
3015 server. Affected file server.c.
3017 * Fixed a bug in silc_server_new_server. The SilcServer was
3018 set as the new server's context instead of SilcServerEntry.
3019 This naturally caused some weird bugs.
3021 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Do not delete the channel rekey task when adding it
3024 for in silc_server_create_channel_key.
3026 * Changed the silc_server_create_channel_key to return
3027 TRUE or FALSE to indicate the success of the channel key
3030 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * Fixed MSVC++ project files and added missing files to
3033 Makefiles under win32/.
3035 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Do not add TCP_NODELAY flag if the operating system
3038 does not have it defined. Affected files are
3039 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3041 * Fixed buffer overflow from Irssi SILC Client. Affected
3042 file irssi/src/fe-common/core/themes.c.
3044 * Fixed double free in client library in the file
3045 lib/silcclient/client.c when disconnecting from server.
3047 * Applied double free patch from cras to Irssi SILC client.
3048 Affected files irssi/src/core/[modules/expandos].c
3050 * Fixed the disconnection handling to Irssi SILC Client.
3051 The application must call silc_client_close_connection
3052 in ops->connect client operation in case of failure of
3053 the connection. Affected file is
3054 irssi/src/silc/core/client_ops.c.
3056 * Do not set sock->protocol to NULL in the function
3057 silc_client_close_connection after executing the protocol's
3058 final callback since the sock might not be valid anymore.
3059 Affected file lib/silcclient/client.c.
3061 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Do not enable SILC_THREADS if the linking with libpthread
3064 did not happen. Affected file configure.in.pre.
3066 * Added notion to protocol specification that server must
3067 verify the sent authentication payload with CMODE when
3068 setting the channel founder key. Implemented it to the
3069 server. Affected file silcd/command.c.
3071 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Added _EXTRA_DIST SILC distribution variable to the
3074 distributions file. It is used to conditionally add extra
3075 files or directories to the specific distribution. Affected
3076 files ./prepare, Makefile.am.pre and distributions.
3078 Removed the `_' from the start of the distribution names.
3081 * Added README.WIN32 for instructions to compile the Toolkit
3084 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Fixed a double free in disconnection in the server. Affected
3087 file is silcd/server.c.
3089 * Fixed the lib/silcske/groups.c to work now also with GMP
3090 MP library. The string conversion did not work when using
3091 specific base and the base is indicated in the string as well.
3093 * Created win32/ directory which now includes MSVC++ specific
3094 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3095 It will appear only in the toolkit distribution
3097 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3099 * Changed the key material distribution function in case when
3100 the hash output is too short. The data is now concatenated
3101 a bit differently than it used to. Made the change to the
3102 SKE protocol specification.
3104 * Added better GMP detection to configure.in.pre. A patch
3107 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Fixed a minor bug in SKE that might cause some problem on
3110 some platforms. Affected file lib/silcske/silcske.c.
3112 * Added the cookie checking for initiator in the SKE. It checks
3113 that the responder returns the sent cookie unmodified. The
3114 affected file is lib/silcske/silcske.c. Added new SKE
3115 error type INVALID_COOKIE that can be sent during the
3116 negotiation. Fixed some memory leaks as well.
3118 * Added the "invalid cookie" error message to Irssi SILC client's
3121 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3123 * Added `task_max' field to the SilcClientParams to indicate
3124 the maximum tasks the scheduler can handle. If set to zero,
3125 default values are used. Affected file lib/silcclient/silcapi.h.
3127 * Fixed memory leaks in silc_client_close_connection. Affected
3128 file lib/silcclient/client.c.
3130 * Added silc_client_del_client_entry to client library to free
3131 all memory of given client entry. Affected file is
3132 lib/silcclient/idlist.[ch].
3134 * Added new functions silc_client_del_channel and
3135 silc_client_del_server to delete channel and server entries.
3136 Affected file lib/silcclient/[silcapi.h/idlist.c].
3138 * Removed silc_client_del_client_by_id from silcapi.h.
3140 * Fixed the INFO command to return the server's own info
3141 correctly when querying by Server ID. Affected file is
3144 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3146 * Removed the non-blocking settings in WIN32 code in the
3147 silc_sock_[read/write] and added SleepEx instead. Affected
3148 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3149 of input data is now checked with FIONREAD and ioctlsocket.
3151 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Call silc_schedule_task_del_by_context in the
3154 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3155 Affected file lib/silccore/silcprotocol.c.
3157 * Call silc_protocol_cancel for active protocols in the
3158 silc_server_close_connection if the funtion
3159 silc_server_free_sock_user_data has not been called.
3160 Affected file silcd/server.c.
3162 * Generic tasks cannot be deleted using the del_by_fd
3163 task deleting function since generic tasks does not match
3164 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3166 * Added a notion to SILCOPER help file that the SILCOPER works
3167 only on router server, not on normal server.
3169 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * Added for WIN32 support for the new scheduler as well.
3172 Affected file lib/silcutil/win32/silcwin32schedule.c.
3174 * Fixed the SHA1 implementation to work on various platforms.
3176 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3178 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3179 API. It is part of the scheduler now. Everything else is
3180 as previously but some functions has changed their names.
3181 Checkout the lib/silcutil/silcschedule.h for the interface.
3182 Updated all applications to use the new interface. Affected
3183 files are lib/silcutil/silcschedule.[ch].
3185 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3187 * Found a bug in the SKE implementation. The HASH value,
3188 specified by the protocol, was not computed correctly. The
3189 public key of the responder was not added to the computation
3190 even though it is mandatory. Affected file lib/silcske/silcske.c.
3191 This unfortunately causes incompatibilities with older
3192 clients and servers.
3194 * Added WIN32 specific network init and uninit functions:
3195 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3196 the Winsock2. Affected file lib/silcutil/silcnet.h and
3197 lib/silcutil/win32/silcwin32net.c.
3199 * Set the socket always to nonblocking mode on WIN32 after
3200 reading data or writing data. Affected file is
3201 lib/silcutil/win32/silcwin32sockconn.c.
3203 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Fixed various compilation problems under WIN32. Affected
3206 files lib/silcutil/win32/silcwin32thread.c and
3207 lib/silcutil/win32/silcwin32schedule.c.
3209 * Removed all _internal.h #includes from public header
3210 files. Internal headers must never be included from
3213 Removed also the lib/silcske/payload_internal.h file.
3215 * All include files that may be needed (public and some others
3216 included by the public headers) by application developers are
3217 now copied to the ./includes directory. It does not copy any
3218 internal headers. Affected file Makefile.defines.pre and all
3219 Makefile.am's under lib/ and subdirs.
3221 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Do not change the ~/.silc directory's permissions automatically.
3224 Affected file irssi/src/silc/core/clientutil.c.
3226 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3228 * Do not cancel the protocol in silc_server_close_connection
3229 it might cause recursion. Now cancelled in the function
3230 silc_server_free_sock_user_data. Affected file silcd/server.c.
3232 * Fixed the silc_server_remove_clients_by_server to regenerate
3233 the channel keys correctly finally. Added also new function
3234 silc_server_remove_clients_channels to actually do it.
3235 Affected file silcd/server.c.
3237 * Fixed the silc_server_new_channel to not crash by giving
3238 wrong router to the new channel. Affected file is
3239 silcd/packet_receive.c.
3241 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3243 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3244 which is given as argument to the silc_client_alloc now.
3245 It can be used to configure the client and set various parameters
3246 that affect the function of the client.
3248 * The USERS command in server did not check whether the channel
3249 is private or secret. Affected file silcd/command.c.
3251 * Added new argument to the USERS command in protocol specification.
3252 The USERS command now can take the channel name as argument
3253 as well. Added support for this in client and server and
3254 updated the protocol specs.
3256 * Completed the GETKEY command in client. It can be now used
3257 to fetch also servers public key not only some clients.
3258 Affected files lib/silcclient/command[_reply].c.
3260 * Added silc_client_get_server to return server entry by the
3261 server name. Affected files lib/silcclient/silcapi.h and
3264 * Redefined the IDENTIFY command in protocol specification to be
3265 more generic. It now can be used to query information about
3266 any entity in the SILC Network, including clients, servers and
3267 channels. The query may be based either the entity's name
3268 or the ID. Added support for this in both client and server.
3270 Affected files silcd/command.c and lib/silcclient/command.c
3271 and command_reply.c.
3273 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3274 the _from_client and _from_server functions. Affected file
3277 * Added silc_client_get_channel_by_id_resolve to the file
3278 lib/silcclient/silcapi.h to resolve channel information by
3279 its ID. Added also silc_client_get_channel_by_id that
3280 does not resolve it from the server.
3282 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * Added SilcServerEntry context into the client library
3285 to represent one server. The INFO command now allocates
3286 these to save the resolved server info. For now on the
3287 client library will also keep information about servers,
3288 connected and resolved with INFO.
3290 The INFO command now allocates the SilcServerEntry context
3291 and saves the server info there. The COMMAND_REPLY in
3292 the INFO now returns the parameters to application in
3293 same order as defined in the protocol specification.
3295 The entries are cached in the client->server_cache.
3297 * The INFO command is now issued after received the Client ID
3298 from the server. Affected file lib/silcclient/client.c.
3300 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3301 to the application as the mode changer might be server.
3302 It is guaranteed that NULL is not returned anymore to the
3303 application. Affected file lib/silcclient/client_notify.c.
3305 The ID Type is now also passed to the application so that
3306 it can check whether the returned entry is SilcClientEntry
3309 Added new function silc_client_get_server_by_id to return
3310 the server entry by ID. Affected files are the
3311 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3313 * Do not create the channel in the Irssi SILC Client when issuing
3314 the JOIN command but when received the sucessful JOIN command
3315 reply. Otherwise the channel might get created even though we
3316 could not join it. The Affected file is
3317 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3319 * Fixed a channel joining bug in router. The router must also
3320 check the channel modes, invite and ban lists etc. when serving
3321 the JOIN command sent by normal server. Affected file is
3322 silcd/command.c. The router now resolves the client's
3323 information from the server who sent the JOIN command if it
3324 does not know it, and processes the JOIN command only after
3327 * Changed the SilcCommandCb to take new argument; void *context2.
3328 Affected file lib/silccore/silccommand.h
3330 The second argument in the command callbacks in the server now
3331 includes the SilcServerCommandReplyContext if the command was
3332 called as pending command callback from the command reply.
3333 Otherwise it is NULL. When called as pending the status of the
3334 command reply will be checked and if it was erronous the
3335 error will be sent to the original sender of the command.
3336 This way the client always receives the error messages even
3337 though the server was actually the one who received the error
3338 when it resent the command to router, for example. Affected
3339 files silcd/command[_reply].[ch].
3341 * Fixed sending WHOWAS command's error message to client if
3342 the requested client could not be found. It was missing.
3345 * Changed the CMODE and CUMODE commands reply arguments in the
3346 protocol specification. The Channel ID is now sent in both
3347 of the commands to identify the channel. Implemented this
3348 new feature to the client and server. Affected files
3349 lib/silcclient/command_reply.c and silcd/command.c.
3351 * Made better checks for invite and ban lists in the JOIN
3352 command in server. Affected file silcd/command.c.
3354 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3356 * The server now performs the incoming host IP/DNS lookup
3357 using the silc_socket_host_lookup and thus does not block
3358 the server anymore. Affected file silcd/server.c.
3360 * Completed the multi-thread support for SILC Scheduler in
3361 the lib/silcutil/silcschedule.c.
3363 * Fixed the configure.in.pre to detect the pthread correctly
3366 * Fixed a deadlock in silc_task_queue_wakeup in the file
3367 lib/silcutil/silctask.c.
3369 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3371 * Added new function silc_schedule_wakeup that is used in
3372 multi-threaded environment to wakeup the main thread's
3373 schduler. It needs to be used when a thread adds a new task
3374 or removes a task from task queues. After waking up, the
3375 scheduler will detect the task queue changes. If threads
3376 support is not compiled in this function has no effect.
3377 Implemented the wakeup mechanism to both Unix and WIN32
3378 systems. Affected files are lib/silcutil/silcschedule.[ch],
3379 lib/silcutil/unix/silcunixschedule.c and the
3380 lib/silcutil/win32/silcwin32schedule.c.
3382 * Added new function silc_task_queue_wakeup to wakeup the
3383 scheduler by the specified task queue. Affected file
3384 lib/silcutil/silctask.[ch].
3386 * The silc_socket_host_lookup_start now wakes up the scheduler
3387 after adding the timeout task. Affected file is
3388 lib/silcutil/silcsockconn.c.
3390 * The silc_socket_host_lookup is synchronous now if the threads
3391 support is not compiled in. However, the callback is still
3392 called asyncronously through the scheduler, anyway. Affected
3393 file lib/silcutil/silcsockconn.c.
3395 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3397 * Added new function silc_socket_host_lookup to perform
3398 asynchronous IP and FQDN lookups for the socket connection.
3399 Affected files lib/silcutil/silcsockconn.[ch].
3401 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3403 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3404 that may or may not compile the mutex support in.
3406 Changed the silc_mutex_alloc interface. It allocates the
3407 mutex now to the sent pointer and returns TRUE or FALSE.
3409 Affected file lib/silcutil/silcmutex.h.
3411 * Wrote the SILC Task Queue interface to support multi-threads.
3412 Affected file lib/silcutil/silctask.[ch].
3414 * Wrote the SILC Scheduler to support multi-threads. Affected
3415 file lib/silcutil/silcschedule.c.
3417 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3419 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3420 in lib/silcutil/win32/.
3422 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * Defined SILC Mutex API and SILC Thread API and implemented
3425 them for Unix. Affected files are
3426 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3427 lib/silcutil/unix/silcunixmutex.c and
3428 lib/silcutil/unix/silcunixthread.c.
3430 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Fixed the silc_server_remove_clients_by_server's channel
3433 key re-generation. The hash table handling was incorrect
3434 and would not work with many channels. Affected file is
3437 * Fixed some memory leaks around the server code.
3439 * Rewrote the silc_server_get_users_on_channel to support IPv6
3440 based Client ID's. Affected file silcd/server.c.
3442 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3443 specification. However, a separate document must be written
3444 to define the detailed signing procedure and the payload
3445 associated with the flag. Defined the flag to the
3446 lib/silccore/silcchannel.h as well.
3448 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Changed the dynamic tables to static size tables in the
3451 lib/silccrypt/silchmac.c.
3453 * Removed GCC dependencies from the code. A patch by cras.
3455 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3457 * Do not show the error "Error receiving packet bla bla"
3458 in server if it really was not an error (-2 means that reading
3459 is pending). Affected file silcd/server.c.
3461 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Fixed a possible crash in silc_server_remove_clients_by_server
3464 in silcd/server.c. Fixed there also some memory leaks.
3466 * Fixed the silc_idlist_replace_client_id. It could replace
3467 wrong key in the hash table. Affected file silcd/idlist.c.
3469 * Do not check whether there are global users on the channel
3470 if the channel->global_users is FALSE. Affected functions
3471 silc_server_remove_from_one_channel and
3472 silc_server_remove_from_channels in silcd/server.c. Also,
3473 do not check if the removed client is local as we can be
3474 sure that global client was not removed from the channel
3475 and checking for global users is not needed.
3477 * The silc_server_remove_clients_by_server now re-generates
3478 the channel keys correctly for those channels that had
3479 clients removed from them. Affected file silcd/server.c.
3481 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3483 * Found the reason of random crashes in the server. We weren't
3484 ignoring the SIGPIPE signal (which can be sent in write())
3485 and it crashed the server. Affected file silcd/silcd.c.
3487 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3489 * Assure that sock->user_data is not NULL in the function
3490 silc_server_packet_send in silcd/packet_send.c.
3492 * Disconnect the remote connection if it could not be added
3493 to any ID lists in the server. The affected file is
3496 * Check in silc_server_packet_send[_real/dest] that the
3497 socket is not disconnecting and ignore the data if it is.
3498 Affected file silcd/packet_send.c.
3500 * Define inline to __inline on native WIN32 compilation.
3501 Affected file includes/silcwin32.h.
3503 * Added some explicit type casts for inline code since MSVC
3504 require them. Affected files lib/silcutil/silcbuffer.h,
3505 lib/trq/silcdlist.h and lib/trq/silclist.h.
3507 * Print warning in log files from now on if the packet
3508 decryption fails. Affected file silcd/server.c.
3510 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Changed the `say' client operation's interface to accept
3513 new `type' argument to indicate the type of the message sent
3514 by the library. The application may filter the library's
3515 messages according the type. The affected file is the
3516 lib/silcclient/silcapi.h.
3518 * Added two new functions to lib/silcclient/silcapi.h:
3519 silc_client_del_client and silc_client_del_client_by_id.
3520 Affected file lib/silcclient/idlist.c.
3522 * Moved the clientincludes.h from includes/ to silc/ and
3523 serverincludes.h from includes/ to silcd/.
3525 * The modes for the CMODE and CUMODE are now passed as
3526 uint32 for application with COMMAND_REPLY. The affected
3527 file is lib/silcclient/command_reply.c.
3529 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * /WHOIS without arguments shows client's own information.
3532 Affected file lib/silcclient/command.c.
3534 * Changed PING to not accept any arguments. The specs
3535 says that client can ping only the connected server so
3536 requiring an argument is not needed. Affected file is
3537 lib/silcclient/command.c.
3539 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Fixed a fatal bug in private message sending and reception
3542 encryption and decryption when using private message keys.
3543 The implementation was incorrect and did not follow the
3544 specification. It causd that some of the message were
3545 lost since it did not use the sending and receiving keys
3546 as the protocol suggests. This has been fixed and will cause
3547 incompatibilities with older clients when sending private
3548 message encrypted with private message keys. Affected files
3549 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3550 and various other in Irssi SILC Client.
3552 Added `responder' boolean argument to the functions
3553 silc_client_add_private_message_key[_ske] to indicate when
3554 the key is added as responder or initiator of the key
3557 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Removed the silc_ske_check_version function and created
3560 a SilcSKECheckVersion callback. Added also a function
3561 silc_ske_set_callbacks that is now used to set all SKE
3562 callbacks. The callback functions are not given to
3563 the SKE functions anymore, but this function is used to
3566 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3568 * Added `silc_version' argument to the silc_client_alloc
3569 to define the version of the application for the library.
3570 The library will use the version string to compare it
3571 against the remote host's (usually a server) version
3572 string. Affected file lib/silcclient/silcapi.h
3574 * Added the KE protocol context to Key Agreement context
3575 in client library so that we can abort the SKE if it
3576 is in process when we get timeout. Affected file is
3577 lib/silcclient/client_keyagr.c.
3579 * Do not resolve the client ID forever if it returns in the
3580 first time that such client does not exist. This was done
3581 for example with private message. Affected file is
3582 lib/silcclient/client_prvmsg.c.
3584 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Do not add regex.h for WIN32. The affected file
3587 includes/silcincludes.h.
3589 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3590 not work yet 100%. It generates the DLL's automatically
3591 when compiling with --with-win32 under cygwin.
3593 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * lib/contrib/regex.c is not compiled on WIN32.
3597 * Added silc_net_get_socket_opt function to the
3598 lib/silcutil/silcnet.h.
3600 * Added includes/silcwin32.h for WIN32 specific includes
3603 * Do not use ptime structure or any of the posix process
3604 functions on WIN32 in lib/silccrypt/silrng.c.
3606 * Added silc_gettimeofday to provide generic function
3607 for struct timeval on all platforms. Added the function
3608 to lib/silcutil/silcutil.h.
3610 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3613 library as they clearly belong there. As a plus side we
3614 can make the actual socket connection routines platform
3617 Added also new generic function silc_socket_read and
3618 silc_socket_write (that used to be silc_packet_[read/write].
3619 The implementation of these are platform specific.
3621 * Added WIN32 specific routines of silc_socket_[read/write]
3622 to lib/silcutil/win32/silcwin32sockconn.c.
3624 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Added preliminary support for native WIN32 compilation under
3627 cygwin (using the -mno-cygwin option for GCC) to the
3628 ./configure.in.pre. The --with-win32 now prepares the
3629 compilation for native WIN32.
3631 * Rewrote the SILC Scheduler interface in the file
3632 lib/silcutil/silcschedule.h. The scheduler is now context
3633 based and does not have anymore any global static scheduler.
3634 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3635 and created lib/silcutil/win32 directory for WIN32 based
3638 * Added Unix specific network routines to the
3639 lib/silcutil/unix/silcunixnet.c and the old
3640 lib/silcutil/silcnet.c includes now only generic routines.
3642 Added WIN32 specific network routines to the
3643 lib/silcutil/win32/silcwin32net.c.
3645 * Added Unix specific utility functions from the
3646 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3648 * Added WIN32 SILC Scheduler to the file
3649 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3652 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Do not handle JOIN notify in the server if the target client
3655 is not registered (idata->registered == FALSE). The affected
3656 file is silcd/packet_receive.c.
3658 * Update the nickrec->founder in event_cumode in the Irssi SILC
3659 client. Affected file irssi/src/silc/core/silc-channels.c.
3661 * Fixed the CUMODE_CHANGE notify handling in the server when
3662 server and router are announcing their clients on channels.
3663 Now the mode changes are saved and notified correctly. The
3664 affected file is /silcd/packet_receive.c.
3666 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3667 They really did not replace the cache entry in the ID Cache.
3668 Now they do that. Affected file silcd/idlist.c.
3670 * Fixed the KICK notify handling in the Irssi SILC client to
3671 update the channel records so that the kicked client does not
3672 appear to be on the channel. The affected file is
3673 irssi/src/silc/core/silc-channels.c.
3675 * Always update the conn->current_channel when executing command
3676 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3678 * Fixed the KILL notify handling in Irssi SILC client to remove
3679 the killed client on all channels.
3681 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Fixed the silc_parse_command_line to remove extra spaces
3684 from the start and end of the arguments. Affected file is
3685 lib/silcutil/silcutil.c.
3687 * Cancel and free any active protocol in the function
3688 silc_server_close_connection. Affected file silcd/server.c.
3690 * Cancel and free any active protocol in the function
3691 silc_client_close_connction. Affected file is
3692 lib/silcclient/client.c.
3694 * Do not execute the KILL command for clients that are in
3695 history (ie. they are not in the network). Affected file is
3698 * Fixed KILL notify handling, client does not crash anymore.
3699 Affected file irssi/src/silc/core/silc-channels.c.
3701 * Reduced the default packet buffer size from 2048 to 1024 in
3702 lib/silccore/silcpacket.c.
3704 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3705 counter to the SKE context that is incresed when the SKE library
3706 performs async operation outside the library. If the outside
3707 process frees the SKE context and FREED status will be set
3708 and the library will detect after the sync operation that the
3709 libary is freed. The affected files are
3710 lib/silcske/silcske[_status].[ch].
3712 * Resolve the client entry information in the function
3713 silc_client_channel_message to assure that NULL pointer is not
3714 passed as client entry to the application. */
3716 * Fixed the task timeout calculation to assure that there is
3717 never negative timeouts. The affected file is
3718 lib/silcutil/silcschedule.c.
3720 * Fixed the channel user mode notification sending in server.
3721 It was sent point-to-point to the router (or to server by router)
3722 but it needs to be destined to a channel. The routines now
3723 supports sending the channel user mode notifys to the channels
3724 when announcing clients and channels. Affected files are
3725 silcd/server.c and silcd/packet_receive.c.
3727 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3728 It did not actually replace the old channel entry in the cache.
3729 Affected file lib/silcclient/client_notify.c.
3731 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Fixed a possible crash in silc_packet_send_prepare. It now
3734 assures always that there is enough space in the buffer and
3735 at the tail area of the buffer (for MAC).
3737 Fixed the inbound buffer reallocation in silc_packet_read.
3738 It was old code and did not handle the reallocation correctly.
3741 The affected file is lib/silccore/silcpacket.c.
3743 * Fixed buffer overflow in silc_parse_nickname in the file
3744 lib/silcutil/silcutil.c.
3746 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * make install generates new server keys only if there is not
3751 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3754 Added check that if the NOREPLY is set then we will not send
3755 the away message. This avoids infinite loop of away messages
3756 if both clients are away. The affected file is
3757 lib/silcclient/client_prvmsg.c.
3759 * Fixed client crash if /NICK was given without arguments.
3760 Affected file lib/silcclient/command.c.
3762 * Server does not send the invite list in INVITE command back
3763 to the client if the list was not altered. Added this notion
3764 to the protocol spec as well. Affected file silcd/command.c.
3766 Fixed possible crash in INVITE command by checking the
3767 value of silc_server_get_client_route command.
3769 * Fixed the INVITE notify type handling. The arguments are now
3770 taken in correct order and client does not crash. The affected
3771 file is irssi/src/silc/core/silc-channels.c.
3773 Removed the "Inviting xxx to channel" message from the
3774 client library away and let the application handle it.
3775 Affected file lib/silcclient/command.c. Added that message
3776 to Irssi SILC client's message formats.
3778 * Fixed CMODE command crash in client. It now checks the
3779 amount of arguments correctly and does not crash. The affected
3780 file is lib/silcclient/command.c.
3782 * Do not create new channel automatically in silc_channels_join
3783 but check whether the channel by that name already exists.
3784 Affected file irssi/silc/core/silc-channels.c.
3786 * Do not send the SERVER_SIGNOFF to router if the disconnected
3787 entity was the router. Affected file silcd/server.c.
3789 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3790 SILC client as it was missing from there.
3792 Added the handling of the KICK notify to the Irssi SILC client
3793 as it was missing. Added "you have been kicked" message to
3794 Irssi SILC client's message modules formats.
3796 Added the handing of the KILL notify to the Irssi SILC client
3797 as it was missing. Added the kill message module formats
3800 The affected file is irssi/src/silc/core/silc-channels.c.
3802 * The router did not save the channel mode the server announced.
3803 Affected file silcd/packet_receive.c.
3805 * Fixed a possible crash in INFO command in server. If the
3806 server did not provide the server info it crashed. Affected
3807 file silcd/command.c.
3809 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Fixed the GETKEY command in the server to check also the
3812 global list. Otherwise the GETKEY would not work correctly
3813 in normal SILC server. Affected file silcd/command.c.
3815 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Fixed GETKEY crash, it crashed if the command did not succseed.
3819 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3822 is now real and not just an macro interface to GMP.
3824 Removed the entire GMP from the source tree and imported new
3825 NSS MPI library instead. Reason for removing GMP is that it is
3826 extremely large and compiles extremely slow. The NSS MPI
3827 is only a few files and compiles in less than 10 seconds.
3828 The speed is also about the same as GMP. The MPI is imported
3829 to lib/silcmath/mpi.
3831 If the system has GMP installed we will still use the GMP.
3832 If it is not then the NSS MPI will be compiled.
3834 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Merged a long nickname (127 characters long) crash bugfix from
3837 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3839 * Merged a freed memory reference bugfix from Irssi CVS tree.
3840 Affected file irssi/src/core/commands.c.
3842 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Added the server's public key sving and verification to the
3845 server when performing the SKE. This was missing and the
3846 remote server's (or router's) public key was accepted without
3847 checking whether we have it previously or trust it at all.
3848 Affected file silcd/protocol.c.
3850 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Check in the silc_server_timeout_remote if protocol is active
3853 and make sure that the protocol's final callback is called so
3854 that all memory if freed. Affected file silcd/server.c.
3856 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * silc_server_whois_send_reply crashed the server if the nickname
3859 was 127 characters long. Affected file silcd/command.c.
3861 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Added sanity check to the silc_server_new_client. If the hostname
3864 is provided inside username then check that the provided hostname
3865 really is the same as the resolved one. If the hostname was not
3866 resolved then check it from the public key. Affected file is
3867 silcd/packet_receive.c.
3869 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3870 if the server disconnected us and the connection is not valid
3871 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3873 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3874 the library to the lib/silcutil/silcutil.[ch].
3876 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Close log file after open. Affected file
3879 lib/silcutil/silclog.c.
3881 * Check whether sock == NULL in silc_client_send_packet and return
3882 if it is. Affected file lib/silcclient/silcclient.c.
3884 * Check rec->entry == NULL in the Irssi SILC Client before
3885 sending the channel message. Affecte file is
3886 irssi/src/silc/core/silc-servers.c.
3888 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Merged a splitted window bugfix from Irssi CVS tree. The
3891 affected file is irssi/src/fe-text/textbuffer-view.c.
3893 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3894 It did not print nickname.
3896 * Improved the distributions system a bit.
3898 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3901 irssi/src/fe-text/gui-window.c.
3903 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3904 to in-active server. The affected file is
3905 irssi/src/silc/core/client_ops.c.
3907 * Resolve the client in USERS command reply if the entry does
3908 not have username resolved. The affected file is
3909 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3910 command to WHOIS command to really resolve stuff. The USERS
3911 is not used any more in any critical section so WHOIS can
3912 be used even though it might be slower than IDENTIFY.
3914 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3917 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Changed the protocol API a bit more consistent in the
3920 lib/silccore/silcprotocol.[ch].
3922 * Changed the following headers to ROBODoc format:
3924 lib/silccore/silcpayload.h
3925 lib/silccore/silcprotocol.h
3926 lib/silccore/silcsockconn.h
3928 All core library headers are now formatted.
3930 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Fixed a bug in Irssi SILC client; do not show that you are
3933 server/router operator if you really are not. Affected file is
3934 irssi/src/silc/core/client_ops.c.
3936 * Renamed silc_command_free_payload to silc_command_payload_free.
3937 Affected file lib/silccore/silccommand.h
3939 * Added silcmath.h to include the prototoypes of various routines
3940 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3943 * Changed the following headers to ROBODoc format:
3945 lib/silccore/silcchannel.h
3946 lib/silccore/silccommand.h
3947 lib/silccore/silcid.h
3948 lib/silccore/silcidcache.h
3949 lib/silccore/silcmode.h
3950 lib/silccore/silcnotify.h
3951 lib/silccore/silcpacket.h
3952 lib/silcmath/silcmath.h
3954 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added checking to the server code not to start the server if
3957 ciphers and stuff are not configured properly. Affected files
3958 silcd/serverconfig.[h] and silcd/server.c.
3960 * Changed the layout of the header files of the public interfaces
3961 in the SILC libraries. The new layout supports ROBODoc
3962 documentation tool (and some others) so that it is easy to create
3963 a library reference manual. All the other headers and source
3964 code must still follow the CodingStyle document. Also source
3965 code must not include these ROBODoc stuffs, only the headers.
3966 Furthermore, all public interface headers must now be named
3967 by using `silc' prefix, example: silcapi.h, silccipher.h.
3968 Some files were renamed due to this. All the other headers
3969 must not be used as public interfaces. I will update the
3970 CodingStyle document later. Changed following headers, so far:
3972 lib/silcclient/silcapi.h
3973 lib/silccore/silcauth.h
3974 lib/silccore/silcprivate.h
3975 lib/silccrypt/silcdh.h
3977 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Removed silc_client_packet_send_flush from the client library
3982 as it is not needed. Affected file lib/silcclient/client.[ch].
3984 * Added printing of message of unresolved authentication method
3985 to the Irssi SILC client. Added it to the module formats.
3986 Removed the same message from the client library.
3988 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Added new distribution feature, DISTLABEL. Every distribution
3991 can define own preprocessor label that can be used in the
3992 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3993 file distributions, acconfig.h.pre and prepare.
3995 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added Makefile.defines_int to include the actual definitions
3998 for Makefile.defines.in. Tested the new distribution system,
3999 created distributions and tested installation.
4001 * Added AWAY message printing to the Irssi SILC client. Added
4002 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4004 * Added SCONNECT command to call the SILC's CONNECT command.
4005 Cannot use CONNECT directly since Irssi uses that internally.
4006 Affected file irssi/src/silc/core/silc-servers.c.
4008 Added ACTION local command. It is same as ME command but takes
4009 the channel as mandatory argument.
4011 Rewrote some of the Irssi's help files to suite for SILC
4014 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Added Makefile.defines[.in] that should for now on be included
4017 in all Makefile.am file in the source tree. That file includes
4018 all common compilation definitions for SILC source tree.
4020 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Minor changes to the ./prepare script to change the package
4023 name according the distribution name to the configure.in.
4025 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Created new distribution system. Added file `distributions'
4028 that defines all the distributions that can be created out of
4029 the SILC source tree. The ./prepare script now reads that
4030 file to determine how to prepare the distributions. The
4031 first argument to the ./prepare is the name of the distribution
4032 and second is the version of the distribution. If given
4033 without arguments it creates the default (toolkit) distribution
4034 with the default version (defined in ./prepare).
4036 All Makefile.am files that are subject to the distributions
4037 are now named as Makefile.am.pre. These are ./Makefile.am
4038 and lib/Makefile.am. Others may be changed later.
4040 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added invite list, ban list, some key management and connection
4043 error message printing to module formats in the Irssi SILC client.
4045 * Added new silc_client_set_away_message to set the away message
4046 that is back to the person who sent private message. The
4047 affected file lib/silcclient/silcapi.h and the
4048 lib/silcclient/client_prvmsg.c.
4050 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Fixed the private message sending in the Irssi SILC client,
4053 added local command KEY to the Irssi SILC client.
4055 Added key management and key agreement message formats to the
4056 irssi/src/fe-common/silc/module-formats.[ch].
4058 Added USERS (alias WHO) printing, server/router operator
4059 indication and LIST command printing to the module formats.
4061 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Fixed channel joining notify handling, cumode notify handling
4064 from Irssi SILC client.
4066 * Added SILC specific module-formats to the Irssi SILC client so
4067 that SILC specific message hilighting, colors etc is possible.
4068 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4070 Added channel mode, channel user mode, actions, notices,
4071 whois and whowas printing to the the module-formats.c.
4073 * Fixed a bug in channel deletion in the server. The channel
4074 is not left to the cache even if the channel founder auth mode
4075 is set when there are no users anymore on the channel. Affected
4076 file silcd/server.c.
4078 * The silc_net_localhost now resolves the entire hostname including
4079 the domain name. Affected file lib/silcutil/silcnet.c.
4081 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Changed the ask_passphrase client operation to be ascynchronous.
4084 It has now a completion callback and a context that the
4085 application must call after it has got the passphrase from
4086 the user. Affected files lib/silcclient/silcapi.h,
4087 lib/silcclient/protocol.c, lib/silcclient/command.c and
4090 Added SilcAskPassphrase callback that the application calls
4091 to deliver the passphrase to the library.
4093 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4094 The public key verification and especially a certificate
4095 verification is asynchronous procedure.
4097 Added new SILC_SKE_STATUS_PENDING status to indicate the
4098 request is pending and a callback will be called to finalize
4101 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4102 indicate that remote end did not send its public key (or
4103 certificate), even though we require it. Added check for this
4104 condition in the SKE. This was a security bug, now fixed.
4106 Defined new SilcSKEVerifyCbCompletion callback that is called
4107 when the verification process is completed.
4109 The affected files lib/silcske/silcske_status.h and
4110 lib/silcske/silcske.[ch].
4112 * Changed the verify_public_key client operation to be async
4113 as well. Defined SilcVerifyPublicKey callback that is used to
4114 indicate the success of the public key verification process.
4116 Changed the server and client to use the new async client
4119 * Changed the Irssi SILC client's internal scheduler to be called
4120 twice as many times as it used to be. As a result the client
4121 should be a bit faster now. Affected file is
4122 irssi/src/silc/core/silc-core.c.
4124 * Added support to Irssi SILC client of asynchronous public key
4125 verification and passphrase inquiry. Affected file is
4126 irssi/src/silc/core/silc-core.c.
4128 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Do not say "You have left channel %s" in client library.
4131 Moved it to the application. Affected files are
4132 lib/silcclient/command.c and silc/client_ops.c.
4134 * Fixed silc_client_get_clients. Command context was not
4135 duplicated and was freed memory in the callback. Affected
4136 file lib/silcclient/idlist.c.
4138 * Do not say "you are now talking..." on JOIN command in the
4139 client library. The appliation must handle it.
4141 * Do not say ".. changed topic to" in command reply in the
4142 client libary. The application must handle it.
4144 * Fixed TOPIC command sending in the client library.
4146 * Fixed a memory leak in silc_client_command_free in the file
4147 lib/silcclient/command.c.
4149 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Imported a modified version of Irssi client to the source tree.
4152 The Irssi will be used to create a new client called
4153 Irssi SILC. Imported to irssi/.
4155 Added silc_core_init_finish function to the Irssi. Affected
4156 file irssi/configure.in.
4158 A lot changes in the Makefile.ams around the irssi tree.
4160 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Do not rehash if the new size is same as the old size of the
4163 hash table, in the silc_hash_table_rehash*. The affected file
4164 lib/silcutil/silchashtable.c.
4166 * Replaced hash_table_del_by_context calls from the server
4167 (when channel->user_list and client->channels) to the
4168 hash_table_del as it is sufficient and faster.
4170 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Added silc_hash_table_list, silc_hash_table_get and the
4173 SilcHashTableList structure to provide an alternative way to
4174 traverse the hash table. The affected files are
4175 lib/silcutil/silchashtable.[ch].
4177 * Changed the server's idlist routines to use the hash table
4178 routines to optimize the code.
4180 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4182 * Replaced the client entry's `channel' list and channel entry's
4183 `user_list' list to hash tables for optimized lookup. Changed
4184 the code to use the hash table interface around the code.
4185 Affected file lib/silcd/idlist.[ch].
4187 * Added `auto_rehash' boolean argument to the function
4188 silc_hash_table_alloc to indicate whether the hash table should
4189 auto-rehash when it thinks is appropriate time. It will
4190 increase the hash table size if the there is twice as much
4191 entries in the table than the size of the table, and will
4192 decrease the size if there are twice as less entries than
4193 the size of the table.
4195 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4199 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * silc_idcache_purge_by_context deletes the entry now by context
4202 as it is supposed to do. Affected file lib/silccore/idcache.c.
4204 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4205 client is not anymore valid (WHOWAS givens the info) and not
4206 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4208 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Removed the `data' and `data_len' arguments from the ID Cache
4211 interfaces and added `name' argument. ID Cache does not handle
4212 anymore the binary data only a names associated with given ID.
4214 * When hashing a Client ID with silc_hash_id the entire ID is
4215 not hashed anymore, instead only the hash of the Client ID is
4216 hashed. This way we can access the Client ID from the cache
4217 with Client ID but with the hash of the ID (which is a hash of
4218 the nickname) as well without any difference in performance.
4220 Added also silc_idcache_find_by_id_one_ext to do one on one
4221 searching when we have the actual ID. Added also function
4222 silc_hash_client_id_compare. The affected files are
4223 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4225 * When hashing the name associated with a ID it is always done
4226 in lowercase. This way we can access the cache without worrying
4227 about case-sensitivity, even though, for example nicknames are
4230 * Fixed a bug in server with channel message sending. It put
4231 wrong ID type as destination ID. The affected file
4232 silcd/packet_send.c.
4234 * silc_idcache_del_by_context now deletes from all hash tables
4235 by context. Affected file lib/silccore/idcache.c.
4237 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Changed the client library to use the new ID Cache interface.
4240 Changes around the source tree.
4242 * Added silc_hash_table_rehash_ext to rehash with specific
4243 hash function. Affected file lib/silcutil/silchashtable.[ch].
4245 * Added silc_hash_string_compare to compare two strings in the
4246 hash table. Affected file lib/silcutil/silcutil.[ch].
4248 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Added new function silc_idcache_del_by_context into the
4251 lib/silccore/idcache.[ch].
4253 * Changed the server's ID list routines to use the new ID Cache
4254 interface. Changes around the source tree.
4256 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Added silc_hash_table_del[_by_context]_ext functions in to the
4259 lib/silcutil/silchashtable.[ch].
4261 Removed silc_hash_table_find_all* routines and added new
4262 silc_hash_table_find_foreach to replace them.
4264 Added silc_hash_table_replace_ext function as extended
4265 replacing function. Separated the simple hash table interface
4266 from the extended hash table interface in the file
4267 lib/silcutil/silchashtable.h.
4269 * Fixed minor bugs and changed it to use some of the new
4270 hash table functions in lib/silccore/idcache.c
4272 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Added new function silc_hash_table_find_all to return all keys
4275 in the hash table by the specified key. As the hash table is
4276 collision resistant it also makes it possible to have several
4277 duplicate keys in the hash table. This function may be used to
4278 find all of the keys from the hash.
4280 Added user_context arguments to the SilcHashFunction,
4281 SilcHashCompare and SilcHashDestructor to deliver user specified
4284 Added new fuctions silc_hash_table_find[_all]_ext to do
4285 extended lookup with specified hash and compare functions and
4286 specified user contexts.
4288 Added new function silc_hash_table_add_ext to add the key
4289 with specified hash function and user context.
4291 Added new function silc_hash_table_foreach to traverse all
4292 entrys in the hash table. Added SilcHashForeach callback
4295 Added new function silc_hash_table_del_by_context to delete
4296 the entry only if the context associated with the key matches.
4298 Affected files are lib/silcutil/silchashtable.[ch].
4300 * Removed silc_hash_[server/client/channel]_id and added just
4301 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4302 silc_hash_id_compare to compare two ID's using as the hash table
4303 comparison function. Added also silc_hash_data to hash
4304 binary data and silc_hash_data_compare to compare it.
4306 * Removed silc_idlist_find_client_by_hash as it is not needed
4307 anymore. Affected file silcd/idlist.[ch].
4309 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4310 to use internally the SilcHashTable. The new ID Cache is a lot
4311 faster than the old one. Some of the ID Cache interface was also
4312 rewritten and obsolete and stupid functions were removed.
4314 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Added entry_count field to the SilcHashTable to keep the number
4317 of the entries in the table. Implemented the function
4318 silc_hash_table_rehash. Added new function
4319 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4321 Fixed a minor bug in silc_hash_table_free.
4323 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4324 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4325 into the lib/silcutil/silcutil.[ch].
4327 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Implemented a collision resistant hash table into the
4330 lib/silcutil/silchashtable[ch]. See the header and the source
4331 for the SilcHashTable API.
4333 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Merged dotconf version 1.0.2 into lib/dotconf.
4337 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Do not compile anything in lib/silcsim/* if the SIM support
4340 is not enabled. The tree should now compile without problems
4343 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Compiled the SILC under cygwin. Compiled and tested briefly
4346 without problems. More tests needed. The SIMs didn't compile
4349 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4351 * Fixed possible crash in silc_get_username in the
4352 lib/silcutil/silcutil.c.
4354 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Fixed a va_arg in silc/client_ops.c.
4358 * Oops, RC5 routines were named AES and caused some problems
4359 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4361 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Added new SilcIDIP structure into the lib/silccore/id.h and
4364 replaced the old `ip' fields from all SILC ID's to that type.
4365 This is a step towards IPv6 support.
4367 The silc_id_get_len takes now the ID as an extra argument.
4368 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4369 both IPv4 and IPv6 based ID's.
4371 The affected files are lib/silccore/id.[ch] and other files
4372 around the tree using these routines.
4374 * Removed the ID length arguments in server from various
4375 silc_server_send_notify_* routines -> they are not needed
4378 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Fixed memory leak in silc_encode_pem_file in the file
4381 lib/silcutil/silcutil.c.
4383 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Check minor version as well in the SKE. Affected files are
4386 silcd/protocol.c and lib/silcclient/protocol.c.
4388 * Added --identifier option to the server so that an identifier
4389 can be when creating the public key for the server. Affected
4390 file is silcd/silcd.c.
4392 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4393 lib/silccrypt/silcpkcs.c.
4395 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Register default ciphers and stuff when using -C option with
4398 the server. Affected file sildc/silcd.c.
4400 * Put back the servers public key filename format, it is better
4401 than the new one. For now, the client keys are saved with the
4402 new filename format. The affected file silc/client_ops.c.
4404 * Implemented the Cipher API for the rest of the ciphers that
4405 did not implement it or implemented it the wrong way.
4407 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Register default ciphers and stuff when using the -S option
4410 in the client. Affected file silc/silc.c. Same also when
4411 creating new key pair with -C option.
4413 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Fixed the silc_verify_public_key client operation function to
4416 save the public keys differently. The fingerprint is now
4417 used as filename and not the hostname. This way also the
4418 client keys are saved uniquely and not with hostnames. The
4419 affected file is silc/client_ops.c.
4421 * Trimmed the silc_hash_fingerprint function to remove extra
4422 whitespaces from the end of the fingerprint. The affected
4423 file is lib/silccrypt/silchash.c.
4427 * Added silc_cipher_register_default function to register all
4428 default ciphers. It can be used when configuration files
4429 does not exist and the application does not want any specific
4430 ciphers in any specific order.
4432 The SilcDList is now used as silc_cipher_list dynamically
4433 allocated cipher list. Removed the static list all together
4434 and now all ciphers must be allocated to the dynamic list.
4435 The silc_cipher_alloc routine was changed to check only the
4438 All silc_cipher_* routines that used to return int returns
4441 The affected files lib/silccrypt/silccrypt.[ch].
4443 * The same thing was done to silc_hash_* as for silc_cipher_*
4444 routines. Affected files lib/silccrypt/silchash.[ch].
4446 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4447 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4448 Added also silc_pkcs_[un]register[_default] functions.
4449 Removed the data_context from the PKCS API.
4451 * Added silc_hmac_register_default function to register default
4452 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4453 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4454 to unregister all hmacs at once.
4456 * Register the default ciphers, hash functions, PKCSs and HMACs
4457 if client's configuration file does not exist. The affected
4460 * The client did not load the hash functions from the SIM
4461 modules at all. Added support for this. Affected file is
4462 silc/clientconfig.c.
4464 * When decoding public key with silc_pkcs_public_key_decode, check
4465 the supported algorithm only if PKCS are registered. Affected
4466 file lib/silccrypt/silcpkcs.c. The same was done with the
4467 silc_pkcs_private_key_decode.
4469 * Fixed the SILC List routines to keep the list always in order.
4470 It used to change the list's order when traversing the list but
4471 not it preserves the order. Affected file lib/trq/silclist.h.
4473 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Added the client library to use the SilcSocketConnection's
4476 reference counter (by silc_socket_dup) to prevent the bug that
4477 the socket object may be freed underneath async operation.
4479 * The name resolv library checking fixes in the configure.in.pre.
4482 * Created new version of the protocol drafts for future
4483 development. The -03 drafts are the ones that will be changed
4484 in the trunk now and the -02 will remain as they are.
4486 * Send list of CUMODE notifys to the router when announcing
4487 the channel users to the router. Affected file silcd/server.c.
4488 If the router receiving channel founder CUMODE for a channel
4489 that already has channel founder it will send CUMODE notify
4490 to the sender to remove the channel founder rights from the
4491 announced client. Affected file silcd/packet_receive.c.
4493 * The CUMODE notify may now use Server ID as well as the entity
4494 who changes the mode. Updated protocool specs.
4496 * Updated INSTALL and README files.
4498 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * New web pages in the http://silc.pspt.fi. The pages was
4505 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Implemented the [DenyConnectin] config section in the server.
4508 Added silc_server_config_denied_conn to check whether incoming
4509 connection is denied. Affected file silcd/serverconfig.[ch].
4511 * Do not check the ports when checking the incoming configuration
4512 data if the port is 0, meaning any. Affected file is
4513 silcd/serverconfig.c.
4515 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Fixed buffer overflow in silc_string_compare in the file
4518 lib/silcutil/silcutil.c.
4520 * Fixed double free in silc_server_command_leave in the file
4523 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Fixed the version checking in the server. Affected file is
4528 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Fixed the configuration data fetching when accepting new
4531 connections in the server. Affected file silcd/server.c.
4533 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * Added `sender_entry' argument to the function
4536 silc_server_packet_relay_to_channel so that we can check
4537 whether some destination actually belongs to the same route
4538 the sender belongs (ie, we must not resend the packet to the
4539 sender). Affected file silcd/packet_send.[ch].
4541 * Added `servername' field to the SilcClientEntry in the server
4542 to hold the name of the server where client is from. Affected
4543 file is silcd/idlist.h.
4545 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Moved the channel message encrypting in the router betwen
4548 router connections from silc_server_channel_message to the
4549 silc_server_packet_relay_to_channel since we want to check
4550 whether we have anybody channel before encrypting anything.
4551 Affected files silcd/packet_[receive/send].c.
4553 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Fixed the [AdminConnection] server config section to support
4556 multiple entries. Affected file silcd/serverconfig.c.
4558 * Added support into the server to check the validity of the
4559 incoming connection before executing any KE or authentication
4562 * The connection configuration is now saved to the KE and
4563 connection auth protocol contexts and not fetched anymore in
4564 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4566 * The local hosts listenning address and port is also resolved
4567 now when starting the server. We want to have the socket object
4568 to include the real address and port for the listener. Added
4569 new function silc_net_check_local_by_sock into the files
4570 lib/silcutil/silcnet.[ch].
4572 * Fixed a broadcast bug in server -> do not broadcast if we
4575 * Fixed a routing bug. Do not route broadcast packets ever.
4576 Broadcast packets must be processed always and not routed since
4577 they may be destined to some other host than yourself and thus
4578 would get routed without no good reason. Affected file is
4581 * Added function silc_server_config_is_primary_route to check
4582 whether primary router connection has been configured (a router
4583 configuration that we are initiating). If there is not, we
4584 will assume that there is only two routers in the SILC network
4585 and we will use the incoming router connection as our primary
4586 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4588 * Changed the order of the broadcasting. Broadcast _after_ the
4589 packet has been processed not before. Affected file is
4592 * Fixed a [ClientConnection] parsing bug. The port was never
4593 parsed correctly thus resulting to port 0. Affected file
4594 silcd/serverconfig.c.
4596 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4597 argument and did not set the broadcast packet flag. Affected
4598 file silcd/packet_send.c. Fixed same bug in the function
4599 silc_server_send_notify as well.
4601 * If we receive NEW_ID packet for our own ID in the server, ignore
4604 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Removed the nickname from the Private Message Payload.
4609 Updated the code and the protocol specs.
4611 * Updated protocol specs for submitting to the IETF.
4613 * Tweaked the Random Number Generator a bit. Affected file
4614 lib/silccrypt/silcrng.c. Exported a new function
4615 silc_rng_[global]_add_noise which can be used to add more
4618 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Do not parse packets with different timeout when protocol
4621 is active -> may cause problem with rekey. Affected file
4624 * When server receives signoff notify it must not create
4625 new channel key if the client is on any channels since the
4626 sender of the signoff notify will create it.
4628 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Added printing of error messages during SKE protocol from the
4631 failure packet sent by server during SKE. Affected file
4634 * Removed the client's failure_callback handling with timeout
4635 and handle it immediately when received.
4637 * The SKE library returned wrong type in SUCCESS and FAILURE
4638 packets. They must be 32 bit MSB not 16 bit MSB.
4640 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Ok, rewrote the logic of the re-key and now it seems to work.
4643 I tested it on high traffic with frequent re-keys without
4644 problems. Added hmac_receive (and renamed hmac to hmac_send)
4645 in SilcClientConnection in lib/silcclient/client.h and
4646 in SilcIDListData in silcd/idlist.h. Also, removed the
4647 SilcPacketParserContext's cipher and hmac fields as they are
4648 not needed anymore and actually caused some problems when
4649 the ciphers and hmac's changed underneath the packet parser.
4651 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4653 * If re-key protocol is active then process the incoming packets
4654 synchronously since we must assure that icoming packets encrypted
4655 with the old key is processed before the new keys is set to
4656 use. This is true other packets than for REKEY packets.
4657 Affected file silcd/server.c. The same was done to client library
4658 as well, affected file lib/silcclient/client.c.
4660 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Fixed bug in client and server to accept the force send if
4663 the packet is send from silc_[server/client]_packet_process
4664 function. Otherwise the packets are never delivered, oops.
4666 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Disable force sending of packets when REKEY protocol is active.
4669 We must assure that no packet is sent directly when rekey is
4670 performed. All packets must be sent through packet queue.
4671 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4672 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4673 function is silc_[server/client]_packet_send_real to check
4676 * Replaced the SIM paths from example config files to
4677 /usr/local/modules. Also, make install creates now
4678 /usr/local/silc/logs directory to hold all the SILC server
4681 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Made the configure.in.pre work on Solaris. Patch by salo.
4685 * Made all ciphers compatible with non-x86 machines. Defined
4686 CBC mode macros into lib/silccrypt/ciphers_def.h.
4688 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Fixed the make install.
4692 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * When MAC computation fails the silc_packet_decrypt returned 0
4695 even though it was supposed to return -1. Fixed this. The
4696 affected file is lib/silccore/silcpacket.c.
4698 * Do not replace the config files in /etc/silc (in make install)
4699 if they already exist. Affected file ./Makefile.am.
4701 * Do not send re-key packets immediately but through packet queue.
4702 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4704 * Changed silc_net_check_host_by_sock to return FALSE if the
4705 IP/DNS could not be resolved. Though, it returns the IP address
4706 now even if it could not resolve it (but returns also FALSE).
4707 Affected file lib/silcutil/silcnet.[ch].
4709 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Added silc_pkcs_decode_identifier to decode the public key's
4712 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4713 Added also silc_pkcs_free_identifier. Added also new context
4714 SilcPublicKeyIdentifier.
4716 * Added -S option to the silc client. It is used to dump the
4717 contents of the specified public key file.
4719 * Changed the PKCS api to return the public key length when
4720 setting the public key.
4722 * Fixed a fatal bug in the public and private key file loading.
4723 Affected file lib/silccrypt/silcpkcs.c.
4725 * Execute the packet parsing for client with zero (0) timeout
4726 if the protocol is active. Affected file silcd/server.c.
4728 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Made the key generation options to the silcd program. Added
4731 -C option, equivalent to client's option.
4733 * Added new [ServerKeys] config section to the server. It
4734 configures the server's public and private key.
4736 * Defined generic Public Key Payload into the protocol
4737 specification to send specific type of public keys and
4740 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4741 public key or certificate.
4743 * Implemented the GETKEY command to the server and to the
4744 client library and on user interface.

4752 * Added SilcServerRekey context into silcd/idlist.h.
4754 * Added the PFS support as defined in the specification to the
4755 SKE protocol. Affected files lib/silcske/*.c.
4757 * Added `ske_group' field to the SilcServerRekey context to hold
4758 the number of the SKE group that is used with PFS in re-key.
4759 Affected file silcd/idlist.h.
4761 * Added PFS re-key support to the server. Affected file is
4764 * Added silc_protocol_cancel to cancel execution of the next
4765 state of the protocol. Affected file is
4766 lib/silccore/silcprotocol.[ch].
4768 * Added the re-key support with and without PFS to the client
4769 library. Re-key is performed once in an hour, by default.
4771 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4772 Added silc_client_rekey_callback and silc_client_rekey_final.
4773 Affected files are lib/silcclient/protocol.[ch] and
4774 lib/silcclient/client.[ch].
4776 * Removed the `hmac_key' and `hmac_key_len' fields from the
4777 SilcClientConnection structure; not needed. Affected file is
4778 lib/silcclient/client.h.
4782 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Do not ask whether user wants to use the negotiated private key
4785 for private messages, just use it. Affected file is
4786 silc/local_command.c.
4788 * Added `send_enc_key' and `enc_key_len' fields to the
4789 SilcIDListData structure since they are needed in the re-key
4790 phase. Affected file is silcd/idlist.[ch].
4792 * Implemented the simple re-key protocol into the server.
4793 Affected files silcd/server.c and silcd/protocol.[ch]. The
4794 re-key will be performed once in an hour, by default.
4796 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4797 Added silc_server_rekey, silc_server_rekey_callback and
4798 silc_server_rekey_final.
4800 * Removed Tunneled flag from the protocol. Updated the code
4801 and the specifications.
4803 * Adde `pfs' field to the SilcIDListData to indicate whether
4804 the PFS is to be performed in the re-key. Affected file is
4807 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4810 int64 of at least the xintXX size. If void * is less that 4
4811 bytes uint32 * will be used. Defined bool as boolean.
4813 * Changed _ALL_ unsigned long and unsigned int to uint32,
4814 unsgined short to uint16 in the source tree.
4816 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4817 not handle clients that has entry->data.registered == FALSE.
4818 They are not in the network anymore. Affected file is
4821 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Implemented the sending of the SERVER_SIGNOFF notify in the
4824 server. Affected file is silcd/server.c.
4826 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4827 Added also silc_notify_payload_encode_args into the
4828 lib/silccore/silcnotify.[ch].
4830 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4831 Affected file silcd/packet_receive.c.
4833 * Implemented the SERVER_SIGNOFF notify handling in the client
4834 library. Affected file lib/silcclient/client_notify.c. Also,
4835 implemnted the printing of the SERVER_SIGNOFF info to the
4836 application. Affected file silc/client_ops.c.
4838 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4839 if the deleting was successful. Affected file silcd/idlist.[ch].
4841 * Added support for public key authentication in the connection
4842 authentication protocol in the client library. Affected file
4843 lib/silcclient/protocol.c.
4845 * Changed the server's silc_idlist_get_clients_by_* interface
4846 to support already allocated array so that new entries may be
4847 added to pre-allocated array. Affected file silcd/idlist.[ch].
4848 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4849 and command replies.
4851 * All command reply functions in the server now calls the
4852 pending command callback even if error occured. This way the
4853 error will be delivered to the client as well. Affected files
4854 silcd/command.c and silcd/command_reply.c.
4856 * Fixed INFO command to return local server's info if no server
4857 was provided. Affected file lib/silcclient/command.c.
4859 * Removed RESTART command for good. Updated the code and the
4862 * Rewrote parts of the task system. It is a bit simpler now.
4863 Removed unsued task priorities. The affected files are
4864 lib/silcutil/silctask.[ch].
4866 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Moved the USERS printing from the library to the application.
4869 Affected files lib/silcclient/command.c and silc/client_ops.c.
4871 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Added channel key re-key support. The re-key is perfomed
4876 only by the router and is done once in an hour. Added `rekey'
4877 field to the SilcChannelEntry in the server. Affected files
4878 silcd/server.c and silcd/idlist.h.
4880 * Added silc_task_unregister_by_context into the file
4881 lib/silcutil/silctask.[ch].
4883 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Added SILC_UMODE_GONE mode to indicate when the client is not
4886 present in the SILC network. Added also support to the local
4887 command AWAY that will set this mode. Added support of showing
4888 "xxx is gone" in WHOIS command. The USERS command shows the
4889 gone status as well.
4891 * Fixed setting server and router operator privileges in the
4892 server's UMODE command. Affected file silcd/command.c.
4894 * Merged the SKE KE1 and KE2 payloads into one payload. The
4895 new KE payload is equivalent to the old KE2 payload.
4897 Cleaned up the SKE Start Payload parsing. It now uses the
4898 simple buffer unformatting to do the parsing. A lot faster
4901 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4902 to the SKE that is used to indicate whether both of the SKE
4903 parties should perform authentication. By default only the
4904 responder performs authentication. By setting this flag also
4905 the initiator must do authentication. By default it is unset
4906 since in normal SKE case, client to server connection, only
4907 the responder should do authentication. When doing SKE between
4908 two clients both should perform authentication. Updated the
4909 code and the protocol specs.
4911 * A little fix to IDENTIFY command in the server. Search the
4912 client first by hash not nickname. Affected file is
4915 * Fixed the silc_client_close_connection to support closing
4916 the client to client connections wihtout deleting too much
4917 data. Affected file lib/silcclient/client.c.
4919 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4920 are received if protocol used to be active but is not anymore
4921 the application would crash due to NULL pointer dereference.
4922 Affected files silcd/server.c and lib/silcclient/client.c.
4924 * Added `hash' field to the SilcClientConnection to include
4925 the hash function negotiated in the SKE protocol.
4927 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4928 to set the channel founder authentication data. A client can
4929 claim the founder rights later by providing the authentication
4930 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4931 This way the channel founder can regain the channel founder
4932 privileges even it is left the channel. This works only on
4933 local server and the client must be connected to the same
4934 server to be able to regain the founder rights. Updated the
4935 protocol specs accordingly.
4937 Added support to the CMODE command in the client to set the
4938 founder auth data. Read the README to see how to set it.
4940 Added support to the CUMODE command to claim the founder
4941 rights. Read the README to see how to do it.
4943 Added support for the founder authentication to the Channel
4944 Entry in the server. Affected file silcd/idlist.h.
4946 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4947 server's CMODE command. Affected file silcd/command.c.
4949 * Added the following new functions into lib/silccore/silcauth.[ch]:
4950 silc_auth_get_method and silc_auth_get_data.
4952 * The server now saves the remote hosts public key to the
4953 SilcIDListData pointer. Affected file silcd/protocol.c.
4955 * The normal server now does not remove the channel entry from
4956 the cache if the founder authentication data is set. It used
4957 to remove it if the founder was the last one on the channel on
4958 the server and left the channel. The auth data is saved and
4959 if the channel is re-joined later the old entry is used with
4960 the old auth data. Affected files silcd/command_reply.c and
4963 * Removed the `pkcs' field from the SilcIDListData structure
4964 in the server; it is not used. Affected file silcd/idlist.h.
4966 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Fixed packet processing on slow links. Partial packets were
4969 never re-processed because the incoming data buffer was cleared
4970 by the application. Application must not directly clear the
4971 sock->inbuf, the packet processing routines handle it. Fixed
4972 this in client library and in server.
4974 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Fixed the WHOIS and IDENTIFY send reply function to really
4977 check whether to send list or just one entry. Affected file
4980 * Cleaned up the LEAVE command's channel key distribution. The
4981 affected file silcd/command.c.
4983 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4984 can enforce the channel mode as well. In that case the ID
4985 includes the ID of the server. The code now enforces the
4986 mode change if the router have different mode than the server.
4988 * The notify client operation with CMODE_CHANGE notify can now
4989 return NULL client_entry pointer if the CMODE was not changed
4990 by client. Application must check for this.
4992 * Added <Server ID> argument to INFO command to support server
4993 info fetching by Server ID.
4995 * Added silc_server_announce_get_channel_users to get assembled
4996 packets of channel users of the specified channel. Affected
4997 file silcd/server.[ch].
4999 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5000 was freed underneath the ID Cache.
5002 * Re-announce clients when the server received CHANNEL_CHANGE
5003 notify from the router. Affected file silcd/packet_send.c.
5005 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5008 crashed since it did not handle the fact that there is no cipher
5009 called "3" and didn't check the error condition. Now fixed.
5011 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5012 flag. It can be used to send message requests.
5014 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Implemented the RESTART command in the client.
5018 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5019 notice type messages. Added notice printing to the user
5022 * The channel keys are not re-generated if the channel's mode
5023 is PRIVKEY, ie private key on the channel exists. Affected
5024 files silcd/server.c and silcd/command.c.
5026 * Fixed a little bug in channel message delivery when channel
5027 private keys are set in the server. Affected file is
5028 silcd/packet_send.c.
5030 * Changed the setting on channel->on_channel = TRUE from the
5031 silc_client_save_channel_key to the JOIN command reply. The
5032 key payload is not received if the private channel key is set.
5033 Affected file lib/silcclient/command_reply.c and the
5034 lib/silcclient/client_channel.c.
5036 * When the CMODE_CHANGE notify is sent and the channel private
5037 key mode is removed the channel key must be re-generated in
5038 other cells as well. Added this support for the router in the
5039 silcd/packet_receive.c.
5041 * Added new local command NOTICE to send notice message on
5042 channel. Affected file silc/local_command.[ch].
5044 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Added new local command ME to the client. It is used to send
5047 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5048 some action. Affected file silc/local_command.[ch].
5050 * Changed channel_message and private_message client operations
5051 to deliver the message flags to the application. Added also
5052 the `flags' arguments to the silc_client_send_channel_message
5053 and silc_client_send_private_message functions. Affected file
5056 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Redefined the Private Message Payload to support private message
5059 keys and to support the new private message flags. Updated
5060 the protocol specs. Flags makes it possible to have for example
5061 CTCP style messages.
5063 * Added new type SilcPrivateMessagePayload and defined an API
5064 for it in the lib/silcclient/silcprivate.[ch].
5066 * Tested private message private keys successfully. Tested the
5067 private message key set, unset and list commands with the new
5070 * Redefined the Channel Message Payload to include the channel
5071 message flags (equal with private message flags) to support
5072 for example CTCP style messages.
5074 * Defined some of the message (for channel and private message)
5075 flags. Updated the protocol specs and added the flags to the
5076 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5078 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Added SilcKeyAgreementStatus type to the key agreement routines
5081 to indicate the current status and error if one occured.
5082 The status types are defined in the lib/silcclient/silcapi.h.
5084 * Added new local command KEY that is used to set and unset private
5085 keys for channels, set and unset private keys for private messages
5086 with remote clients and to send key agreement requests and
5087 negotiate the key agreement protocol with remote client. The
5088 key agreement is supported only to negotiate private message keys,
5089 it currently cannot be used to negotiate private keys for channels,
5090 as it is not convenient for that purpose.
5092 * Fixed a minor pending callback setting bug in the function
5093 silc_client_get_client_by_id_resolve, now the function works.
5094 Affected file lib/silcclient/idlist.c.
5096 * Added function silc_net_get_local_port to get local bound
5097 port by socket. Added to lib/silcutil/silcnet.[ch].
5099 * Added `sockets' and `sockets_count' fields to the SilcClient
5100 object. They hold the sockets of the listenning sockets in
5101 the client. Listenning sockets may be for example the key
5102 agreement server. Affected file lib/silcclient/client.[ch].
5103 Added functions the silc_client_add_socket and the
5104 silc_client_del_socket. They are exported to the application
5107 * Added ~./silc/clientkeys to support other client's public keys.
5109 * Renamed verify_server_key client operation to verify_public_key
5110 and added one argument to indicate the type of the connection
5111 (server, client etc.).
5113 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Added silc_server_connection_auth_request to handle the
5116 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5117 silcd/packet_receive.[ch].
5119 * Added silc_server_send_connection_auth_request into the
5120 silcd/packet_send.c to send the connection auth request packet.
5122 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5125 * Fixed the public key authentication in responder side in the
5126 server. The `auth_data' pointer includes the SilcPublicKey
5127 not the path to the public key. Affected file silcd/protocol.c.
5129 * Implemented the public key authentication in the initiator side
5130 in the server. Affected file silcd/protocol.c.
5132 * Removed the [RedirectClient] config section from the server
5133 configuration. Is not needed and I don't want to implement it.
5135 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Cleaned up the CMODE command in the server. It now works
5138 correctly and supports all the modes defined in the protocol.
5139 Affected file is silcd/command.c.
5141 * Added `hmac_name' field to the SilcChannelEntry in the server
5142 to hold the default HMAC of the channel. It can be set when
5143 creating the channel (with JOIN command). Affected files
5146 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5147 type to indicate the change of the current cipher and hmac
5148 on the channel. Client can safely ignore the <cipher> argument
5149 (if it chooses to do so) since the CHANNEL_KEY packet will
5150 force the channel key change anyway. The <hmac> argument is
5151 important since the client is responsible of setting the new
5152 HMAC and the hmac key into use.
5154 * Fixed the CMODE command in the client library as well.
5156 * Tested CMODE command in router environment successfully.
5158 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Show the version of the remote client (or server) when connecting
5161 to the server. It is logged to the log file. Affected file
5162 is silcd/protocol.c.
5164 * Fixed the KILLED notify handling in the client library. The
5165 client must be removed from all channels when receiving the
5168 Also, do not remove the client entry when giving the KILL
5169 command but when the KILLED notify is received.
5171 * Removed silc_idlist_find_client_by_nickname from the server.
5172 Not needed anymore. Affected files silcd/idlist.[ch].
5174 * Implemented the CHANNEL_CHANGE notify type handling to the
5175 server. Affected file silcd/server.c.
5179 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Added silc_server_send_notify_invite to send the INVITE
5182 notify between routers.
5184 * Implemented the INVITE command correctly to the server.
5186 * Implemented the INVITE notify type handling in the server.
5188 * Implemented the INVITE command to the client library and on the
5191 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Added function silc_server_get_client_resolve to find the
5194 client entry by ID from all ID lists and then resolve it
5195 (using WHOIS) if it cannot be found. Affected file is
5198 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Implemented the BAN command to the client library.
5202 * The JOIN command in the server now checks the invite list
5205 * Changed the silc_command_reply_payload_encode_va and the
5206 silc_command_payload_encode_va to support that if argument is
5207 NULL it ignores and checks the next argument. Affected file
5208 lib/silccore/silccommand.c.
5210 * Added silc_server_send_notify_ban to send the BAN notify
5211 type between routers.
5213 * Chaned the silc_notify_payload_encode to support that if
5214 argument is NULL it ignores and checks the next argument.
5215 Affected file lib/silccore/silcnotify.c.
5217 * Tested ban lists in router environment successfully.
5219 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Implemented BAN command to the server, in silcd/command.[ch].
5223 * Removed the BAN and INVITE_LIST modes from the CMODE command
5226 * Added function silc_string_match to regex match two strings.
5227 Affected files lib/silcutil/silcutil.[ch].
5229 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Redefined parts of the SilcChannelEntry in the server to support
5232 the new ban and invite lists.
5234 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Redefined the INVITE command. The same command can be used to
5237 invite individuals to the channel but also to manage the invite
5238 list of the channel (to add to and remove from the invite list).
5239 Updated the protocol specs.
5241 * Added new command SILC_COMMAND_BAN that can be used to manage
5242 the ban list of the channel. Updated the protocol specs.
5244 * Removed the channel modes: the SILC_CMODE_BAN and the
5245 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5246 in the CMODE command. The equivalent features are now available
5247 using INVITE and BAN commands. Updated the protocol specs.
5249 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5250 in the network about change in the current ban list. The notify
5251 type is not used by the client.
5253 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5254 support the invite lists.
5256 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added new function silc_string_regexify that converts string
5259 including wildcard characters into regex string that can
5260 be used by the GNU regex library. Added into the file
5261 lib/silcutil/silcutil.[ch].
5263 Added silc_string_regex_combine to combine to regex strings
5264 into one so that they can be used as one regex string by
5265 the GNU regex library. Added into the file
5266 lib/silcutil/silcutil.[ch].
5268 Added silc_string_regex_match to match two strings. It returns
5269 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5271 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Imported GNU regex to the soruce tree into lib/contrib.
5274 Fixed some compiler warning from the regex.c.
5276 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Fixed MOTD command in the server to work in router environment.
5280 * Fixed the MOTD command in the client library to support
5281 the server argument in the command.
5283 * Added `nickname_len' argument to the silc_idlist_add_client
5284 in the server, as the `nickname' argument may be binary data
5287 * Added silc_idlist_get_channels to return all channels from
5290 * Implemented LIST command to the server. Affected file is
5293 * Implemented the LIST command to the client library and on the
5296 * Added [<user count>] argument to the LIST command reply.
5297 With private channels the user count is not shown.
5299 * Updated TODO and README.
5301 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * The client entry's data.registered must be TRUE even with
5304 global client entry on global client list. The data.registered
5305 is used to check whether the client is anymore in the network,
5306 for example with WHOWAS command so it must be valid.
5308 * Fixed the WHOWAS command in the server. It now actually works
5309 in router environment. Added function into silcd/command_reply.c
5310 silc_server_command_reply_whowas_save.
5312 * Added silc_idlist_purge function to the silcd/idlist.c
5313 to periodically purge the ID Cache.
5315 * Fixed INFO command in the server. It works now in router
5316 environment. Added <server name> argument to the INFO command
5317 reply. Updated the protocol specs.
5319 * Fixed minor bug in silc_idcache_purge to not purge if the
5320 expire value is zero.
5322 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5323 they were buggy because of the WHOWAS information.
5325 * Fixed local command MSG to handle the async resolving of
5326 the remote client properly. It used to fail the first MSG.
5327 Affected file silc/local_command.c.
5329 * Added `data_len' field to SilcIDCache context.
5331 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Update TODO. Todo in commands in the server.
5335 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5338 used by routers as broadcast packet to inform other routers
5339 about the changed user mode.
5341 Implemented the notify handling in the server. Affected file is
5342 silcd/packet_receive.c. Added the function
5343 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5345 * Added new generic Channel Payload and deprecated the New Channel
5346 Payload. The New Channel Payload is now the generic Channel
5349 * Added new argument `mode' to the silc_server_send_new_channel
5350 as it is required in the Channel Payload now.
5352 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5353 and created a new and real SilChannelPayload to represent the
5354 new generic Channel Payload. Implemented the encode/decode
5355 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5357 * Added silc_server_get_client_channel_list to return the list
5358 of channels the client has joined for WHOIS command reply.
5359 Affected file silcd/server.[ch].
5361 * Implemented the channel list sending in the WHOIS command reply
5362 in server and in the client.
5364 Implemented the channel list displaying on the user interface
5365 as well. Affected file silc/client_ops.c.
5367 * Added silc_channel_payload_parse_list to parse list of Channel
5368 Payloads. It returns SilcDList list of SilcChannelPayloads.
5369 Client for example can use this function to parse the list of
5370 channels it receives in the WHOIS command reply. The caller
5371 must free the list by calling silc_channel_payload_list_free.
5372 Affected files lib/silccore/silcchannel.[ch].
5374 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Added one new argument <user mode> to the WHOIS command reply
5377 to return the mode of the user in SILC. Updated the protocol
5380 Implemented it to the server and client.
5382 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Fixed the mode printing on the user interface on joining.
5385 Affected file silc/client_ops.c.
5387 * Implemented the UMODE command and user modes in general to the
5388 client library and to the user interface.
5390 * Implemented the UMODE command to the server.
5392 * The server now sends UNKNOWN_COMMAND error status if client sends
5393 unknown command. Affected file silcd/command.c.
5395 * All server commands now handle the command identifier the right
5396 way when sending the command reply to the client. The client can
5397 use to identify the command replies with the identifier.
5399 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Added silc_server_get_client_route to resolve the route to
5402 the client indicated by the client ID. Affected file is
5405 * Added silc_server_relay_packet as general function to relay
5406 packet to arbitrary destination. This deprecates functions
5407 like _send_private_message_key, _relay_notify etc. Affected
5408 file is silcd/packet_send.[ch].
5410 Removed silc_server_send_key_agreement,
5411 silc_server_send_private_message_key and
5412 silc_server_packet_relay_notify functions from the file
5413 silcd/packet_send.[ch].
5417 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5418 server. Affected file silcd/packet_receive.[ch].
5420 * Implemented the KILL command to the client. Implemented the
5421 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5422 Affected files lib/silcclient/command[_reply].c and
5423 lib/silcclient/client_notify.c. Implemented the KILL notify
5424 printing in the user inteface.
5426 * Fixed a lot silc_parse_nick memory leaks from the client
5427 library in the file lib/silcclient/command.c.
5429 * Changed the silc_server_send_notify_on_channels's `sender'
5430 argument from SilcSocketConnection to SilcClientEntry to
5431 check the sender as entry and not as connection object and not
5432 to send to the client provided as argument. The affected file
5433 is silcd/packet_send.[ch].
5435 * The notify packets that are destined directly to the client used
5436 to not to be processed by the server. Now changed that and the
5437 server processes all notify packets. After relaying the packet
5438 to the client the notify packet is processed in the server.
5440 * The silc_server_free_client_data now checks whether there is
5441 pending outgoing traffic for the client and purges the data to
5442 the network before removing the client entry.
5444 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5447 an client is killed from the SILC Network. Updated the protocol
5450 Added new function silc_server_send_notify_killed to the
5451 silcd/packet_send.[ch].
5453 * Added function silc_server_packet_relay_notify to relay notify
5454 packets that are destined directly to a client. In this case
5455 the server does not process the notify packets but merely relays
5456 it to the client. Affected file silcd/packet_send.[ch].
5458 Added also silc_server_packet_process_relay_notify to check
5459 whereto relay the notify. Affected file is
5460 silcd/packet_receive.[ch].
5462 * Implemented the KILL command to the server.
5466 * Added the backup schema desgined last fall to the protocol
5467 specs for everyone to see. The specification is in the
5468 *-spec-xx.txt draft and the packet type definitions for the
5469 backup routers is in *-pp-xx.txt draft. Thusly, added also
5470 new packet type SILC_PACKET_CELL_ROUTERS.
5472 * A big security problem in the implementation discovered. The
5473 signoff of an client did not cause new channel key generation
5474 which it of course should've done. The channel keys must be
5475 always re-generated when client leaves (or signoffs) the channel.
5476 The silc_server_remove_from_channels funtion now handles
5477 the channel key re-generation.
5479 * Added `sender' argument to the silc_server_send_notify_on_channels
5480 to not to send the client provided as argument. Affected file
5481 silcd/packet_send.[ch].
5483 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Implemented OPER and SILCOPER commands into the server and
5488 * Added silc_auth_verify and silc_auth_verify_data to verify
5489 the authentication directly from the authentication payload.
5490 It supports verifying both passphrase and public key based
5491 authentication. Affected file lib/silccore/silcauth.[ch].
5493 * Added `hash' field to the SilcIDListData structure. It is the
5494 hash negotiated in the SKE protocol. Affected file is
5497 * Slight redesigning of the SilcAuthPayload handling routines.
5498 Do not send SilcPKCS but SilcPublicKey as argument.
5500 * Implemented the public key authentication support to the
5501 serverconfig. The public key is loaded from the provided path
5502 and saved as authentication data to void * pointer. Thus,
5503 changed the unsigned char *auth_data to void *auth_data;
5505 * Fixed SHUTDOWN command to send the reply before the server
5506 is shutdown. :) Affected file silcd/command.c.
5508 * Fixed fatal bug in CONNECT command. The hostname was invalid
5509 memory and server crashed. Affected file silcd/command.c.
5511 * Fixed fatal bug in CLOSE command. The server_entry became
5512 invalid but was referenced later in the command. Affected file
5515 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Fixed fatal bug in failure packet handling. Server ignored
5518 the failure and thus crashed when it came.
5522 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5525 that the command may be executed only once in (about) 2 seconds.
5526 The old SILC_CF_LAG flag is same but allows command bursts up
5527 to five before limiting.
5529 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5530 server code. Various commands now includes the CF_LAG_STRICT
5531 flag to disallow any kind of miss-use of the command.
5533 * Fixed the silc_buffer_unformat to not to allocate any data
5534 if the length of the data is zero. It used to allocate the
5535 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5537 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Changed the format of AdminConnection configuration section
5540 in the server. Added username of the admin to the format.
5541 Affected files silcd/serverconfig.[ch].
5543 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5544 to return admin configuration data by host, username and/or
5547 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Implemented WHOWAS command to the server. Added the functions:
5551 silc_server_command_whowas_parse,
5552 silc_server_command_whowas_send_reply,
5553 silc_server_command_whowas_from_client and
5554 silc_server_command_whowas_from_server
5556 * Added <Client ID> argument to the WHOWAS command reply. Updated
5557 the protocol specs accordingly.
5559 * Implemented WHOWAS command and command_reply to the client
5562 Implemented the WHOWAS printing on the user interface.
5564 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added new argument to the WHOWAS command reply, the real name.
5567 It is an optional argument. Updated the protocol specs.
5569 * Added SilcIDCacheDestructor callback that is registered when
5570 the SilcIDCache is allocated. The callback is called when
5571 an cache entry in the ID Cache expires, or is purged from the
5572 cache. Added into lib/silccore/idcache.[ch].
5574 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5575 to destruct the client entries when the cache entry expires.
5576 Other ID Cache's in server and in the client library ignores
5579 * If the ID Cache entry's `expire' field is zero then the entry
5580 never expires. Added boolean `expire' argument to the
5581 silc_idcache_add function in the lib/silccore/idcache.[ch].
5582 If it is TRUE the default expiry value is used.
5584 * Added silc_server_free_client_data_timeout that is registered
5585 when client disconnects. By default for 5 minutes we preserve
5586 the client entry for history - for WHOWAS command.
5588 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added support to the server to enforce that commands are not
5591 executed more than once in 2 seconds. If server receives
5592 commands from client more frequently, timeout is registered
5593 to process the commands. Affected file silcd/command.c.
5594 Added new function silc_server_command_process_timeout.
5596 * Changed NICK_NOTIFY handling in client library to check that
5597 if the client's nickname was changed, so there is no need to
5598 resolve anything from the server.
5600 * Removed error printing from the WHOIS and IDENTIFY commands.
5601 If error occurs then it is ignored silently in the client library.
5602 The application, however, may map the received error to
5603 human readable error string. The application currently maps
5604 the NO_SUCH_NICKNAME error to string.
5606 * Made the command status message public to the application. Moved
5607 them from lib/silcclient/command_reply.c to
5608 lib/silcclient/command_reply.h. The application can map the
5609 received command status to the string with the
5610 silc_client_command_status_message function.
5612 * Added check to the server to check that client's ID is same
5613 as the Source ID in the packet the client sent. They must
5616 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Added dist-bzip hook to the Makefile.am to make bzip2
5619 compressed distributions.
5621 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Server now enforces the maximum length for the nickname and
5624 the channel as protocol specification dictates. 128 bytes for
5625 nickname and 256 bytes for channel name.
5627 * Moved the WHOIS printing to the application. The client libary
5628 does not print out the WHOIS information anymore, the application
5629 must do it. Renamed silc_client_command_reply_whois_print to
5630 the silc_client_command_reply_whois_save.
5632 The client's idle time is also sent to the application now, and
5633 the idle is shown on screen.
5635 * Added silc_client_command_reply_identify_save to save the
5636 received IDENTIFY entries.
5638 * Do not check for channel private keys in message sending and
5639 reception if the channel does not have the PRIVKEY mode set.
5640 Affected file lib/silclient/client_channel.c.
5642 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5645 just surfaced after chaning the JOIN procedure.
5647 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Added silc_client_get_clients_by_list to get client entries
5650 from Client ID list, that is returned for example by JOIN
5651 and USERS command replies. The application should use this
5652 function for example when JOIN command reply is received to
5653 resolve the clients already on the channel (library does not
5654 do that anymore as USERS command reply is not used in the JOIN
5655 procedure anymore). Affected files lib/silcclient/silcapi.h and
5656 lib/silcclient/idlist.c.
5658 * JOIN command reply and USERS command reply returns now SilcBuffer
5659 pointers instead of unsigned char pointers when returning
5660 the client list and mode list.
5662 * Added <Client ID> argument to the JOIN command reply, mainly
5663 for the server to identify for which client the command was
5664 originally sent. Updated protocol specs accordingly.
5666 * Added SilcDlist private_key pointer to the SilcChannelEntry
5667 in the client to support the channel private keys. Affected
5668 file is lib/silcclient/idlist.h.
5670 * Added SilcChannelPrivateKey argument to the function
5671 silc_client_send_channel_message so that application can choose
5672 to use specific private ke if it wants to. If it is not provided,
5673 the normal channel key is used, unless private keys are set.
5674 In this case the first (key that was added first) is used
5675 as the encryption key.
5677 * Implemented the support for channel private key handling.
5678 Implemented the following functions:
5680 silc_client_add_channel_private_key,
5681 silc_client_del_channel_private_keys,
5682 silc_client_del_channel_private_key,
5683 silc_client_list_channel_private_keys and
5684 silc_client_free_channel_private_keys
5686 Affected file lib/silcclient/client_channel.c.
5688 * Added the support for the private keys in the channel message
5689 sending and encryption and in the message reception and
5690 decryption. Affected funtions are
5691 silc_client_send_channel_message and silc_client_channel_message.
5693 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Added SKE's key verify callback to the client library's
5696 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5698 * Removed the statement that server (or router) must send USERS
5699 command reply when joining to the channel so that the client
5700 knows who are on the channel. Instead, the client list and
5701 client's mode list is now sent in the JOIN command reply to the
5702 client who joined channel. This is better solution.
5704 * Added function silc_server_get_users_on_channel and function
5705 silc_server_save_users_on_channel to the silcd/server.[ch].
5707 * Removed function silc_server_command_send_users from the
5710 * Do not show topic on the client library anymore. The topic is
5711 sent in the command reply notify to the application and the
5712 application must show the topic now.
5714 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Added client searching by nickname hash into the IDENTIFY and
5717 WHOIS commands in the server as they were clearly missing from
5718 them. Affected file is silcd/command.c.
5720 * Fixed a bug in private message receiving in the client library.
5721 The remote ID was freed and it wasn't supposed, now it is
5724 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Minor fix to the channel payload; allocate the data area, as it
5727 needs to be of specific length.
5729 * If the key agreement port is zero then the operating
5730 system will define the bound port. Affected files are
5731 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5733 * Added new function silc_channel_payload_decrypt into the file
5734 lib/silccore/silcchannel.[ch].
5736 * Moved the channel message etc, check from silc_packet_decrypt
5737 to applications. The library calls now a generic
5738 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5739 when the packet is either normal or special. This was done to
5740 allow more wide range of checking that was not allowed when
5741 the code was in library. Now applications can do virtually any
5742 checks to the packet and return to the library the decision how
5743 the packet should be processed. Affected files are
5744 lib/silccore/silcpacket.[ch].
5746 Added silc_server_packet_decrypt_check to the server and
5747 silc_client_packet_decrypt_check to the client library.
5749 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5750 to send with specified source and destination information.
5752 * Channel message delivery between routers was broken after the
5753 channel key distribution was fixed earlier. The channel key
5754 was used be to distributed to other routers as well which is not
5755 allowed by the protocol. Now this is fixed and channel keys
5756 really are cell specific and the channel message delivery between
5757 routers comply with the protocol specification.
5759 * Fixed various commands in server to check also the global list
5760 for the channel entry and not just the local list. The affected
5761 file silcd/command.c.
5763 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Added assert()s to buffer formatting and unformatting routines
5766 to assert (if --enable-debug) when error occurs. Affected
5767 file: lib/silcutil/silcbuffmt.c.
5769 * Changed to auto-reconnect to check whether the remote host is
5770 router and register the re-connect timeout if it is. It used
5771 to check that whether we are normal server, but router must do
5772 auto-reconnect with another router as well. Affected file
5775 * Removed the [<key len>] option from CMODE command as the cipher
5776 name decides the key length, nowadays. See the defined ciphers
5777 from the protocol specification.
5779 * Added [<hmac>] option to the CMODE command to define the HMAC
5780 for the channel. Added SILC_CMODE_HMAC channel mode.
5782 * Added [<hmac>] option for the JOIN command so that user can
5783 select which HMAC is used to compute the MACs of the channel
5786 * Added Hmac field to the Channel Message Payload. The integrity
5787 of plaintext channel messages are now protected by computing
5788 MAC of the message and attaching the MAC to the payload. The
5789 MAC is encrypted. Now, it is clear that this causes some
5790 overhead to the size of the packet but rationale for this is that
5791 now the receiver can verify whether the channel message decrypted
5792 correctly and also when private keys are set for the channel the
5793 receiver can decrypt the packet with several keys and check from
5794 the MAC which key decrypted the message correctly.
5796 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5797 lib/silccrypt/silccipher.[ch].
5799 * Added silc_hash_len to return the digest length into the
5800 lib/silcrypt/silchash.[ch].
5802 * Rewrote parts of Silc Channel Payload interface in the
5803 lib/silccore/silcchannel.[ch]. The encode function now also
5804 encrypts the packet and parse function decrypts it.
5806 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Fixed a minor formatting bug in the SKE's key material processing.
5809 It actually might have processed the keys wrong way resulting
5812 * Redefined the mandatory HMAC algorithms and added new algorithms.
5813 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5814 and hmac-md5 truncated to 96 bits. The mandatory is now
5815 hmac-sha1-96. Rest are optional (including the one that used
5816 to be mandatory). Rationale for this is that the truncated HMAC
5817 length is sufficient from security point of view and can actually
5818 make the attack against the HMAC harder. Also, the truncated
5819 HMAC causes less overhead to the packets. See the RFC2104 for
5822 * Added new [hmac] configuration section. The SKE used to use
5823 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5824 is of course wrong. The official names that must be proposed in
5825 the SKE are the ones defined in the protocol specification
5826 (hmac-sha1-96 for example). The user can configure any hmac
5827 using any hash function configured in the [hash] section. At
5828 least, the mandatory must be configured.
5830 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5832 * Added HMAC list to the SKE proposal list. It has now both
5833 hash algorithm list and HMAC list. This makes the protocol
5834 incompatible with previous versions. The SKE now seems to work
5835 the way it is supposed to work, for the first time actually.
5837 * Defined plain Hash algorithms to the protocol specification.
5840 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Implemented support for key agreement packets into the server.
5843 Added functions silc_server_key_agreement and
5844 silc_server_send_key_agreement. Other than these functions,
5845 server has nothing to do with this packet.
5847 * Added support for private message key packets into the server.
5848 Added functions silc_server_private_message_key and
5849 silc_server_send_private_message_key.
5853 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5854 called in the protocol's final callback instead in the END
5855 protocol state. This makes a little more sense and in the same
5856 time in client we can use the same protocol routines for normal
5857 key exchange and to key agreement packet handling as well.
5859 * Added to both client's and server's KE protocol context the
5860 SilcSKEKeyMaterial pointer to save the key material. We will
5861 bring the key material to the protocol's final callback by doing
5862 this. The final callback must free the key material.
5864 * Added SKE's packet_send callback into client's KE protocol
5865 context so that the caller can choose what packet sending function
5866 is used. This way we can use different packet sending when
5867 doing normal SKE when doing key agreement packet handling (in
5868 the key agreement packet handling we do not want to encrypt
5871 * Implemented the responder side of the key agreement routines
5872 in the client. The client can now bind to specified port and
5873 accept incoming key negotiation. The key material is passed
5874 to the application after the protocol is over.
5876 * Implemented the processing of incoming Key Agreement packet
5877 in the client. Added function silc_client_key_agreement to
5880 * Implemented the intiator side of the key agreement routines
5881 in the client. The client can now initiate key agreement with
5882 another remote client. The key material is passed to the
5883 application after the protocol is over.
5885 * Created client_keyagr.c to include all the key agreement
5888 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5889 SILC_TASK_CALLBACK except that it is not static.
5891 * Created client_notify.c and moved the Notify packet handling
5892 from the client.[ch] into that file.
5894 * Created client_prvmsg.c and moved all private message and
5895 private message key routines from the client.[ch] into that file.
5897 * Create client_channel.c and moved all channel message and
5898 channel private key routines from the client.[ch] into that file.
5900 * Changed silc_client_get_client_by_id_resolve to resolve with
5901 WHOIS command instead of IDENTIFY command, in the file
5902 lib/silclient/idlist.c.
5904 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Implemented the SKE's responder side to the Client library.
5908 * When FAILURE is received to the protocol do not trust it
5909 blindly. Register a timeout to wait whether the remote closes
5910 the connection as it should do it, only after that process the
5911 actual failure. This was changed to both client and server.
5913 * Added client_internal.h to include some of the structures
5914 there instead of client.h in lib/silcclient/.
5916 * Added function silc_task_unregister_by_callback to unregister
5917 timeouts by the callback function.
5919 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Some "Incomplete WHOIS info" errors has been appearing on the
5922 log files. Took away the entry->userinfo check from WHOIS
5923 reply sending. The entry->userinfo is now " " if client did not
5924 provide one. I thought this was fixed earlier but something
5925 is wrong still. Let's see if the error still appears.
5927 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Fixed a minor bug in the login when the channel key is
5930 re-generated in the server. It used to generate the key in
5931 wrong order and thus caused problems in the channel traffic.
5933 * Fixed a minor bug in channel key distsribution after
5934 KICK command. The key was not sent to the router even though
5937 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Added silc_ske_process_key_material_data as generic routine
5940 to process any key material as the SILC protocol dictates. The
5941 function is used by the actual SKE library but can be used by
5942 applications as well. This relates to the private message keys
5943 and the channel private keys since they must be processed the
5944 same way the normal SILC session keys. The protocol dictates
5945 this. Affected files: lib/silcske/silcske.[ch].
5947 Added also silc_ske_free_key_material to free the
5948 SilcSKEKeyMaterial structure.
5950 * Defined silc_cipher_set_key function to set the key for
5951 cipher without using the object's method function. The affected
5952 files: lib/silccrypt/silccipher.[ch].
5954 * Implemented silc silc_client_add_private_message_key,
5955 silc_client_add_private_message_key_ske,
5956 silc_client_del_private_message_key,
5957 silc_client_list_private_message_keys and
5958 silc_client_free_private_message_keys functions in the
5961 Added functions silc_client_send_private_message_key to send
5962 the Private Message Key payload and silc_client_private_message_key
5963 to handle incoming Private Message Key payload.
5965 * Added Cipher field to the Private Message Key payload to set
5966 the cipher to be used. If ignored, the default cipher defined
5967 in the SILC protocol (aes-256-cbc) is used.
5969 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Removed lib/silcclient/ops.h file.
5973 Redefined parts of the SILC Client Library API. Created new
5974 file silcapi.h that deprecates the ops.h file and defines the
5975 published Client Library API. Defined also private message key
5976 API and channel private key API into the file.
5978 This is the file that the application must include from the
5979 SILC Client Library. Other files need not be included by
5980 the application anymore.
5982 * Added new key_agreement client operation callback and also
5983 defined the Key Agreement library API for the application.
5985 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5987 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5988 is used by clients to request key negotiation between another
5989 client in the SILC network. If the negotiation is started it
5990 is performed using the SKE protocol. The result of the
5991 negotiation, the secret key material, can be used for example
5992 as private message key.
5994 Implemented the Key Agreement payload into the files
5995 lib/silccore/silauth.[ch].
5997 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Redefined ciphers for the SILC protocol. Added some new ciphers
6000 and defined the key lengths for the algorithms. Changed the
6001 code accordingly. The default key length is now 256 bits.
6003 * Fixed SKE key distribution function silc_ske_process_key_material
6004 when the key length is more than 128 bits. The default key
6005 length in SILC is now 256 bits.
6007 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6008 to indicate unsupported algorithm.
6010 * Renamed rijndael.c to aes.c and all functions as well.
6012 * Fixed a long standing channel key setting bug in client library.
6013 Weird that it has never surfaced before.
6015 * Fixed bug in channel deletion. If the entire channel is removed
6016 then it must also delete the references of the channel entry
6017 from the client's channel list as the client's channel entry and
6018 the channel's client entry share same memory.
6020 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Implemented CONNECT and SHUTDOWN commands in the client.
6024 * Implemented CLOSE command to the client.
6026 * Added the function silc_idlist_find_server_by_name into the
6027 files silcd/idlist.[ch].
6029 Added the function silc_idlist_find_server_by_conn into the
6030 files silcd/idlist.[ch].
6032 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * DIE command was renamed to SHUTDOWN. Updated the both code
6037 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6038 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6040 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6043 * Added function silc_server_create_connection function to create
6044 connection to remote router. My server implementation actually
6045 does not allow router to connect to normal server (it expects
6046 that normal server always initiates the connection to the router)
6047 so the CONNECT command is only good for connecting to another
6050 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6053 or some other client was kicked from the channel.
6055 Implemented the handling of the notify type to both client
6058 Implemented silc_server_send_notify_kicked to send the KICKED
6059 notify. It is used to send it to the server's primary router.
6061 * Implemented the KICK command into server and client.
6063 * Added `query' argument to the silc_idlist_get_client function
6064 to indicate whether to query the client from server or not if
6067 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6068 to indicate that the client is not channel founder.
6072 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Removed the rng context from SilcPacketContext structure and
6075 changed that the packet routine uses the Global RNG API.
6077 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Added support for quit message that client can "leave" on the
6080 channel when it quits the SILC. It is ditributed inside the
6081 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6083 Added silc_server_free_client_data that will take the
6084 signoff message as argument.
6086 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6088 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Updated parts of the protocol specification to keep it up
6093 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6096 payloads in one packet.
6098 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6099 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6100 use now the new List flag.
6102 * Also deprecated the following packet types: REPLACE_ID,
6103 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6105 * Added list support for Notify packet in server.
6107 * Added silc_server_send_notify_channel_change to send the
6108 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6109 the silc_server_send_replace_id.
6111 * Added silc_server_send_notify_nick_change to send the
6112 NICK_CHANGE notify type. Deprecates the function
6113 silc_server_send_replace_id.
6115 * Added silc_server_send_notify_join to send the JOIN notify type.
6116 Deprecates the function silc_server_send_new_channel_user.
6118 * Added silc_server_send_notify_leave to send LEAVE notify type.
6119 Deprecates the function silc_server_send_remove_channel_user.
6121 * Added silc_server_send_notify_cmode and
6122 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6123 types. Deprecates the silc_server_send_set_mode function.
6125 * Added SERVER_SIGNOFF notify type to indicate that server has
6126 quit. This means that all clients on the channel from that
6127 server will drop. This can be also used when netsplit happens.
6129 Deprecated REMOVE_ID packet type since it is not needed anymore
6132 Added silc_server_send_notify_server_signoff to send the
6133 SERVER_SIGNOFF notify type. Deprecates the function
6134 silc_server_send_remove_id.
6136 Added also silc_server_send_notify_signoff to send the
6137 SIGNOFF notify type.
6139 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6140 SILC protocol from this day on. Changed the protocol
6141 specification as well.
6143 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6144 notify type. It is used between routers to notify about
6145 topic changes on a channel.
6147 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6150 * Partly updated the protocol specification to comply with the
6151 changes now made. It is still though a bit outdated.
6153 * The JOIN notify type now takes one extra argument <Channel ID>.
6154 The packet used to be destined to the channel but now the
6155 JOIN type may be sent as list thus it is impossible to
6156 destine it to any specific channel. By adding this argument
6157 it is again possible.
6159 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Added CREDITS file. The CHANGES and CREDITS file will appear
6162 in the distribution as well.
6164 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6167 types in the server's silcd/packet_receive.c.
6169 * Implemented CMODE and CUMODE to work in router environment.
6171 * Fixed minor encoding and decoding buglet from the
6172 lib/silccore/silcmode.c.
6174 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6177 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6179 * Changed all SilcConfigServer* and silc_config_server* to
6180 SilcServerConfig* and silc_server_config*, respectively.
6183 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * Associated the ID (client or server ID) to the Authentication
6186 Payload to avoid any possibility of forging. Updated the
6187 protocol specification and the code accordingly.
6189 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * The RSA key length is now save to the RsaKey context in the
6192 key generation process in lib/silccrypt/rsa.c. The key length
6193 is now used to figure out the maximum size of the block allowed
6194 to be encrypted/signed.
6196 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6197 is equivalent to the silc_mp_mp2bin but does not allocate any
6200 * Changed silc_mp_mp2bin API to take length argument. If it is
6201 non-zero then the buffer is allocated that large. If zero, then
6202 the size is approximated using silc_mp_sizeinbase, which however
6205 * Created Global RNG API which is global RNG that application can
6206 initialize. After initializing, any routine anywhere in the
6207 code (including library) can use RNG without allocating a new
6208 RNG object. This was done to allow this sort of use of the
6209 RNG in code that has no chance to allocate RNG object. All
6210 applications currently allocate this and many routines in the
6211 library use this. Affected file lib/silccrypt/silcrng.[ch].
6213 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6214 it to use the Global RNG API.
6216 * Defined Authentication Payload into protocol specification that
6217 is used during SILC session to authenticate entities. It is
6218 used for example by client to authenticate itself to the server
6219 to obtain server operator privileges.
6221 Implemented this payload into the lib/silccore/silcauth.[ch].
6222 Implemented also routines for public key based authentication
6223 as the new protocol specification dictates.
6225 Moved definitions of different authentication methods from
6226 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6228 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6229 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6230 silc_pkcs_verify_with_hash functions into the file
6231 lib/silccrypt/silcpkcs.[ch].
6233 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * The client entry's userinfo pointer must be always valid.
6236 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6237 will fail since it requires the userinfo. Now, the userinfo
6238 is allocated as "" if actual userinfo does not exist. Actually,
6239 it must exist and it is totally Ok to drop client connections
6240 that does not announce the userinfo. However, we will make
6241 this workaround for now.
6243 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6244 to return the remote port by socket.
6246 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6249 SILC_SERVER_PENDING_EXEC and added an new macro
6250 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6251 data or when error occurs while processing the pending command.
6253 Added new argument `destructor' into silc_server_command_pending
6254 and to the SilcServerCommandPending object. This destructor is
6255 now called after calling the pending callback or if error occurs
6256 immediately. If error occurs the actual pending callback won't
6257 be called at all - only the destructor. The destructor may be
6258 NULL if destructor is not needed.
6260 All this applies for client library code as well. Similar
6261 changes were made there as well for the pending commands.
6263 In the client, the application must now allocate the
6264 SilcClientCommandContext with the silc_client_command_alloc
6267 * Added reference counter to the SilcServerCommandContext. Added
6268 function silc_server_command_alloc and silc_server_command_dup
6271 Same type of functions added to the client library for the same
6274 * Removed the cmd_ident from IDListData away since it is now
6275 global for all connections. It is the command identifier used
6276 in command sending and with pending commands. The affected file
6279 * Added reference counter to the SilcSocketConnection objecet to
6280 indicate the usage count of the object. The object won't be
6281 freed untill the reference counter hits zero. Currently only
6282 server uses this, and client ignores it. The client must be
6283 set to use this too later. The affected files are
6284 lib/silccore/silcsockconn.[ch]. Added also the function
6285 silc_socket_dup to increase the reference counter.
6287 This was mainly added because it is possible that the socket
6288 is removed underneath of pending command or other async
6289 operation. Now it won't be free'd and proper DISCONNECTING
6290 flags, etc. can be set to avoid sending data to connection that
6291 is not valid anymore.
6293 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6294 the connection. After that it sets SILC_SET_DISCONNECTED.
6295 It is, however, possible that the socket data is not still freed.
6296 The silc_server_packet_process now checks that data is not
6297 read or written to connection that is DISCONNECTED. The socket
6298 get's freed when the reference counter hits zero.
6300 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Changed the client operation API: channel_message operation's
6303 `sender' is now the client entry of the sender, not the nickname
6304 and the `channel' is the channel entry, not the channel name.
6306 In the private_message operation the `sender' is now also the
6307 client entry of the sender not the nickname.
6309 Affected file is lib/silcclient/ops.h and all applications
6310 using the client operations.
6312 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Moved the calling of ops->connect() from connect_to_server_final
6315 into receive_new_id functin since that is the point when the
6316 client is actually allowed to send traffic to network. The
6317 affected file is lib/silcclient/client.c.
6319 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6322 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6323 (if needs broadcasting) instead of broadcasting the packets one
6324 by one which would make a burst in the network traffic.
6326 * Added `broadcast' argument to the functions in silcd/server.[ch]
6327 silc_server_create_new_channel[_with_id] to indicate whether
6328 to send New Channel packet to primary router.
6330 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Added new function into the silcd/server.[ch] files:
6333 silc_server_create_new_channel_with_id to create new channel with
6334 already existing Channel ID.
6336 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6337 lib/silccore/silcpacket.h. This packet is used t send list of
6338 Set Mode payloads inside one packet. Server uses this to set
6339 the modes for the channels and clients on those channels, that it
6340 announced to the router when it connected to it. The protocol
6341 specification has been updated accordingly.
6343 * The silc_server_new_channel did not handle the packet coming
6344 from normal server as it normally does not send that. However,
6345 when it announces its channels it does send it. Implemented
6346 the support for that.
6348 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6349 into the file lib/silccore/id.h.
6351 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Fixed memory leaks in the functions silc_idlist_del_client,
6354 silc_idlist_del_channel and silc_idlist_del_server in the file
6355 silcd/idlist.c. All of those leaked like a sieve.
6357 * Fixed some small memory leaks in the client's function
6358 silc_client_notify_by_server.
6360 * Added functions into silcd/server.c: silc_server_announce_clients,
6361 silc_server_announce_channels and silc_server_announce_server.
6362 These functions are used by normal and router server to announce
6363 to its primary router about clients, channels and servers (when
6364 router) that we own. This is done after we've connected to the
6367 These functions effectively implements the following packet types:
6368 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6369 and SILC_PACKET_NEW_ID_LIST.
6371 * Added new functions into the silcd/packet_receive.[ch]:
6372 silc_server_new_id_list, silc_server_new_channel_list and
6373 silc_server_new_channel_user_list to handle the incoming
6374 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6376 * Added support of changing Channel ID in the function
6377 silc_server_replace_id. If the server that announces a channel
6378 to the router already exists in the router (with same name but
6379 with different Channel ID), router is responsible to send
6380 Replace ID packet to the server and force the server to change
6381 the Channel ID to the one router has.
6383 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6384 client that the Channel ID has been changed by the router. The
6385 normal server sends this to the client. Client must start using
6386 the new Channel ID as the channel's ID.
6388 Implemented handling of this new type into lib/silcclient/client.c
6389 into the function silc_client_notify_by_server.
6391 * Added new function silc_idlist_replace_channel_id into the files
6392 silcd/idlist.[ch] to replace the Channel ID.
6394 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Call silc_server_command_identify_check always when processing
6397 the IDENTIFY command in silcd/command.c
6399 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6402 send keepalive packets. The packet can be sent by clients,
6403 servers and routers.
6405 Added function silc_socket_set_heartbeat into the file
6406 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6407 If not set, the heartbeat is not performed. The actual
6408 heartbeat is implemented in the low level socket connection
6409 library. However, application is responsible of actually
6412 Added silc_server_send_heartbeat to send the actual heartbeat
6413 packet into silcd/packet_send.[ch]. Server now performs
6414 keepalive with all connections.
6416 * Added silc_task_get_first function into lib/silcutil/silctask.c
6417 to return the timeout task with shortest timeout. There was a bug
6418 in task unregistration that caused problems. TODO has been
6419 updated to include that task system must be rewritten.
6421 * The client library will now resolve the client information when
6422 receiving JOIN notify from server for client that we know but
6423 have incomplete information.
6425 * Rewrote parts of silc_server_remove_from_channels and
6426 silc_server_remove_from_one_channel as they did not remove the
6427 channel in some circumstances even though they should've.
6429 * Encryption problem encountered in server:
6431 The LEAVE command used to send the Channel Key packet to the
6432 router immediately after generating it. However, the code
6433 had earlier sent Remove Channel user packet but not immediately,
6434 ie. it was put to queue. The order of packets in the router
6435 was that Channel Key packet was first and Remove Channel User
6436 packet was second, even though they were encrypted in the
6437 reverse order. For this reason, MAC check failed. Now, this
6438 is fixed by not sending the Channel Key packet immediately but
6439 putting it to queue. However, this is more fundamental problem:
6440 packets that are in queue should actually not be encrypted
6441 because packets that are sent immediately gets encrypted
6442 actually with wrong IV (and thus MAC check fails). So, packets
6443 that are in queue should be encrypted when they are sent to
6444 the wire and not when they put to the queue.
6446 However, the problem is that the current system has not been
6447 designed to work that way. Instead, the packet is encrypted
6448 as soon as possible and left to the queue. The queue is then
6449 just purged into wire. There won't be any fixes for this
6450 any time soon. So, the current semantic for packet sending
6453 o If you send packet to remote host and do not force the send
6454 (the packet will be in queue) then all subsequent packets to the
6455 same remote host must also be put to the queue. Only after the
6456 queue has been purged is it safe again to force the packet
6459 o If you send all packets immediately then it safe to send
6460 any of subsequent packets through the queue, however, after
6461 the first packet is put to queue then any subsequent packets
6462 must also be put to the queue.
6464 Follow these rules and everything works fine.
6466 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Added new function silc_server_remove_clients_by_server to
6469 remove all client entries from ID list when the server connection
6470 is lost. In this case it is also important to invalidate all
6471 client entires as they hold the invalid server entry. This
6472 fixes fatal bug when server has lost connection and will reconnect
6475 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Made some sanity checks to silc_server_daemonise like to check
6478 whether the requested user and group actually exists.
6480 * Added sanity check to SKE's silc_ske_responder_finish to check
6481 that the public and private key actually is valid.
6483 * Invalidate the client's nickname when receiving Replace ID
6484 packet and the Client ID is being replaced. This means that the
6485 server will query the nickname if someone needs it (client)
6488 * Sort the ID Cache in client library when the ID Cache data
6489 has changed (needs sorting).
6491 * Do not allow for SILC client to create several connections to
6492 several servers. The client does not support windows right now
6493 and generating multiple connections causes weird behaviour.
6495 Irssi-silc client does support windows and can handle several
6496 connections without problems, see: www.irssi.org and SILC plugin.
6498 * Fixed some places where client was added to the IDList. The
6499 rule of thumb is following (in order to get everything right):
6500 If the client is directly connected local client then the
6501 `connection' argument must be set and `router' argument must be
6502 NULL to silc_idlist_add_client function. If the client is not
6503 directly connected client then the `router' argument must
6504 bet set and the `connection' argument must be NULL to the
6505 silc_idlist_add_client function.
6507 * The funtion silc_server_packet_send_local_channel actually did
6508 not check whether the client was locally connected or not. It
6509 does that now. Fixed a bug related to LEAVE command.
6511 * Fixed Remove Channel User payload parsing bug in server's
6512 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6514 * The server's silc_server_save_channel_key now checks also the
6515 global ID list for the channel as it might not be in the local
6516 list. Fixed a bug related to LEAVE command.
6518 * Is this the end of the [<unknown>] buglet that has been lurking
6519 around for a long time? A little for loop fix in server's
6520 silc_server_command_whois_parse that is used by both IDENTIFY
6521 and WHOIS command. At least, this was a clear bug and a cause
6522 of one type of [<unknown>] buglet.
6524 * WHOIS and IDENTIFY commands call the function
6525 silc_server_command_[whois/identify]_check function even if
6526 we are not router server.
6528 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Added --with-gmp configuration option. If set the GMP
6531 is always compiled in the SILC source tree. If not set then
6532 it is checked whether the system has the GMP3 installed. If
6533 it has then the GMP won't be compiled (the system's headers
6534 and library is used), if it doesn't have it then the GMP is
6535 compiled in the SILC source tree.
6537 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * Changed RSA private exponent generation to what PKCS #1
6540 suggests. We try to find the smallest possible d by doing
6541 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6542 not security fix but optimization.
6544 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Added new config entry [Identity] to fork the server and run
6547 it as specific user and group. A patch from Bostik.
6549 * Imported Dotconf configuration library into lib/dotconf.
6550 This will be used to create the SILC configuration files later.
6551 It will appear in the distsribution after this commit.
6553 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * A big code auditing weekend happening. Auditing code for
6556 obvious mistakes, bugs and errors. Also, removing any code
6559 Removed files for being obsolete:
6561 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6562 inline in the file lib/silcutil/silcbuffer.h)
6564 o lib/silcutil/silcbufutil.c (the header has inline versions)
6566 Changed code to fix possible error conditions:
6568 o The buffer formatting routines now check that the destination
6569 buffer really has enough space to add the data. This applies for
6570 both buffer formatting and unformatting
6571 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6572 unformatting was changed to accomodate following rules:
6573 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6574 sent to the function while XXX_*STRING will not allocate or copy
6575 the data into the buffer. Instead it sets the pointer from the
6576 buffer into the pointer sent as argument (XXX_*STRING used to
6577 require that the pointer must be allocated already). This change
6578 makes this whole thing a bit more consistent and more optimized
6579 (note that the data returned in the unformatting with XXX_*STRING
6580 must not be freed now). The routines return now -1 on error.
6582 o Tried to find all code that use buffer_format and buffer_unformat
6583 and added return value checking to prevent formatting and
6584 especially unformatting errors and possible subsequent fatal
6587 o Changed ske->x and ske->KEY to mallocated pointers in
6588 lib/silcske/silcske.h. Fixed possible data and memory leak.
6590 o Added return value checking to all *_parse* functions. Fixed
6591 many memory leaks as well.
6593 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6594 so that buffer overflows would not happen. All code now also
6595 checks the return value as it can fail.
6597 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Added reconnection support to server if the normal server looses
6600 its connection to the router (for example if router is rebooted).
6601 The server performs normal reconnection strategy implemented
6602 to the server. Affected file silcd/server.c.
6604 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Added new packet type SILC_PACKET_SET_MODE that is used to
6607 distribute the information about changed modes (for clients,
6608 channels and clients channel modes) to all routers in the
6609 network. Updated the protocol specification accordingly.
6611 Added functions into silcd/packet_send.c and
6612 silcd/packet_receive.c: silc_server_send_set_mode,
6613 silc_server_set_mode.
6615 Added new files silcmode.[ch] into lib/silccore that implements
6616 the encoding and decoding of Set Mode Payload. Added new type
6617 SilcSetModePayload. Moved the definitions of different modes
6618 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6620 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Oops, a little mistake in server's connection authentication
6623 protocol. The protocol is not ended with FAILURE but with
6624 SUCCESS if the authentication is Ok. :) Affected file is
6627 * Implemented NICK_CHANGE notify handling in server in the file
6628 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6629 the local clients on the channel. After the changing nickname
6630 in router environment snhould work and the [<unknown>] nickname
6631 should appear no more.
6633 The silc_server_replace_id function that receives the Replace ID
6634 payload now sends the NICK_CHANGE notify type also in the file
6635 silcd/packet_receive.c
6637 * Changed WHOIS and IDENTIFY command to support the maximum amount
6638 of arguments defined in protocol specs (3328 arguments). This
6639 fixed a bug that caused problems when there were more than three
6642 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6644 * Added extra parameter, command identifier, to the
6645 silc_client_send_command so that explicit command identifier
6648 Changed that ID list routines uses specific command identifier
6649 when sending WHOIS/IDENTIFY requests to the server so that they
6650 can be identified when the reply comes back.
6652 Affected files lib/silcclient/command.[ch],
6653 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6655 * Added `sender' argument to silc_server_packet_send_to_channel
6656 to indicaet the sender who originally sent the packet to us
6657 that we are now re-sending. Ignored if NULL. Affected file
6658 silcd/packet_send.[ch].
6660 * Added some server statistics support in silcd/server_internal.h
6661 SilcServerStatistics structure and around the server code. Also
6662 send some nice statistics information when client is connecting
6665 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * Fixed channel ID decoding in server's JOIN command reply in
6668 silcd/command_reply.c
6670 * Fixed braodcasting of replace ID payload to not to send it if
6671 we are standalone server in silcd/packet_receive.c.
6673 * Fixed all channel message sending routines to not to send
6674 packets to clients that has router set, since they are routed
6675 separately in the same function earlier. Affects file
6676 silcd/packet_send.c and all channel packet sending functions.
6678 * In USERS reply, res_argv[i] are not allocated, the table
6679 is allocated. Thus changed that free the table, not its
6682 * In server's whois_check and identify_check if the client is
6683 locally connected do not send any WHOIS commands - they are not
6686 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6688 * Fixed some minor bugs in client when sending WHOIS command. The
6689 arguments was in wrong order.
6691 * Removed statis function add_to_channel from server in
6692 silcd/command.c that was previously used with the joining but
6695 * Tested USERS command in router environment successfully with two
6696 routers, two servers and two clients.
6698 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Reorganized the USERS command and command reply in client library
6701 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6702 When the command is given by user we register a pending command
6703 callback that will reprocess the command after the reply has been
6704 received from the server. When reprocessing the packet we then
6705 display the information. Thus, the USERS information is displayed
6706 now in the command callback instead of in the command reply
6707 callback. The processing of the command is same as previously
6708 when server has sent the command reply in the JOINing process.
6710 * Added to USERS command in silcd/command_reply.c to join the client,
6711 we didn't use to know about, to the channel after we've created
6712 a client entry for it. Also, for clienet we did know already still
6713 check whether it is on the channel or not and add it if not.
6715 * Removed silc_server_command_join_notify as the function and its
6718 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Changed the client's pending command handling to the same as the
6721 server's pending command handling. It is also now possible to
6722 execute command reply functions from other command reply
6723 function as the function callbacks for commands and command
6724 replies are one and same. The pending commands are not static
6725 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6726 in client connection context. Thus, pending commands are server
6727 connection specific as it is convenient.
6729 Changed the function silc_client_command_pending and
6730 silc_client_command_pending_del and added new function
6731 silc_client_command_pending_check. Removed the
6732 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6735 * Added cmd_ident, current command identifier, to the client
6736 connection context in lib/silcclient/client.h to keep track on
6737 command identifiers used in command sending. Client's command reply
6738 function handling now supports the mandatory command identifiers.
6740 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6741 funtions in client to fully support pending command callbacks.
6743 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6744 as one of the arguments to the application in the command reply
6747 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6748 before first releasing SILC but came back. Now it is removed again
6749 and should come back nomore. The FORWARDED flag was used only
6750 by the JOINing procedure by forwarding the command packet to router.
6751 Now, the JOINing procedure has been changed to more generic (due
6752 to various router environment issues) and FORWARDED is not needed
6753 anymore for anything. The protocol specification is yet to be
6756 Now, removed silc_server_packet_forward from server and the flag
6757 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6759 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Renamed NAMES command to USERS command. The NAMES was named that
6762 due to historical reasons. Now it is renamed. Also, rewrote
6763 parts of the USERS command. The nickname list is not sent anymore
6764 by the server. Only Client ID and mode lists are sent in the USERS
6765 command. Changed this also to the protocol specification.
6767 The client now resolves the names and stuff after it receives
6768 the USERS list from the server when joining to the channel.
6770 * WHOIS and IDENTIFY commands has been changed to support multiple
6771 Client ID's per command. One can now search for multiple users
6772 in the network by sending only one WHOIS or IDENTIFY command.
6773 Changed the code and the protocol specifications.
6775 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6776 uses silc_server_command_whois_parse to parse the request. */
6778 * If normal server, do not parse the WHOIS and IDENTIFY requests
6779 before sending it to the router. Saves some time.
6781 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6783 * Fixed JOIN command on client library. Wrong number of arguments
6784 used to crash the client.
6786 * Added silc_server_channel_has_global function to check whether
6787 channel has global users or not.
6789 * Added silc_server_channel_has_local function to check whether channel
6790 has locally connected clients on the channel.
6792 * The silc_server_remove_from_one_channel now checks whether the
6793 channel has global users or not after given client was removed from
6794 the channel. It also checks whether the channel has local clients
6795 on the channel anymore. If it does not have then the channel entry
6796 is removed as it is not needed anymore.
6798 * The silc_server_notify now checks on JOIN notify whether the joining
6799 client is one of locally connected or global. If it is global then
6800 the channel has now global users on the channel and that is marked
6801 to the channel entry. Also, it now saves the global client to
6802 global list who is joining and JOINs it to the channel. This is
6803 for normal server, that is.
6805 Changed silc_server_send_notify_on_channel,
6806 silc_server_packet_relay_to_channel and
6807 silc_server_packet_send_to_channel check if we are normal server
6808 and client has router set (ie. global client) do not send the
6809 message to that client, as it is already routed to our router.
6811 * Implemented LEAVE notify type handling in silc_server_notify
6814 * Tested LEAVE command in router environment successfully. Tested
6815 with two routers, two servers and two clients.
6819 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6821 * Implemented SIGNOFF notify type handling in silc_server_notify
6824 * silc_server_remove_id now removes the client entry from all channels
6825 it has joined and thusly sends SIGNOFF notify type.
6827 * Rewrote the NAMES list generation in server by removing two excess
6828 loops. The lists are created now inside one loop.
6830 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * silc_server_remove_channel_user checks now also global list
6833 for channel and client.
6835 * silc_server_new_channel_user checks now both local and global
6836 list for channel and client. Fixed a bug in client id decoding.
6837 Used to decode wrong buffer.
6839 * silc_server_channel_message checks now both local and global
6840 list for channel entry.
6842 * Tested channel joining (hence JOIN) in router environment
6843 successfully. Tested with two routers, two servers and two
6846 * Tested channel message sending in router environment successfully.
6848 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Added silc_server_save_channel_key into server.[ch] to save the
6851 received channel key in Channel Key payload processing. It is
6852 also used in JOIN command reply handling.
6854 Equivalent function silc_client_save_channel_key added into
6855 client.[ch] into client library.
6857 * Changed JOIN command reply to send information whether the channel
6858 was created or not (is existing already) and the channel key
6859 payload. Changed protocol specs accordingly.
6861 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6862 the request was sent by ID and not by nickname. Crashed on
6865 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6868 now correctly save the received data.
6870 * silc_server_free_sock_user_data now notifies routers in the
6871 network about entities leaving the network.
6873 At the same time implemented functions silc_server_remove_id
6874 and silc_server_send_remove_id to receive and send REMOVE_ID
6875 packets. The packet is used to notify routers in the network
6876 about leaving entities. The ID removed will become invalid in
6879 * Added function silc_idlist_del_server into server. Removes and
6880 free's server entry from ID list.
6882 * silc_server_private_message function now checks, if we are router,
6883 that the destination ID really is valid ID, naturally.
6885 * In router when NEW_ID packet is received (for new client) the
6886 hash of the Client ID is saved in the ID Cache but the
6887 client->nickname is set to NULL, instead of putting the hash
6890 IDENTIFY command now also checks that client->nickname must be
6891 valid. If it is not if will request the data from the server who
6892 owns the client. Added new function
6893 silc_server_command_identify_check.
6895 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6896 to set the command to already allocated Command Payload.
6898 * Tested private message sending in router environment with two
6899 routers, two servers and two clients. Fixed minor bugs and now
6902 * Fixed segfault from client's NAMES command. Used to crash if
6905 * Forwarded packets must not be routed even if it is not destined
6906 to the receiver. Changed server code comply with this.
6908 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Added `require_reverse_mapping' boolean value to ServerParams
6911 structure. If TRUE (not default) the server will require that
6912 the connecting host has fully qualified domain name.
6914 If the reverse mapping is not required and hostname could not be
6915 found the IP address is used as hostname.
6917 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Implemented version string checking to both client and server.
6920 The check is incomplete currently due to the abnormal version
6921 strings used in development version of SILC.
6923 * Changed all command functions in server to use the new
6926 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6928 * Changed char *data to unsigned char *data in ID Cache system to
6929 support binary data as ID Cache data. Changed code to support
6930 binary data in lib/silccore/idcache.c.
6932 * Renamed silc_server_packet_relay_command_reply to
6933 silc_server_command_reply as it is normal packet receiving
6934 function. Rewrote the function to accept command replys for
6935 servers and not only for clients.
6937 * Mark remote router always as registered server if we are connecting
6938 to it. Otherwise, commands sent by the router to us are ignored.
6940 * All ID List find routines now returns the ID Cache Entry pointer
6941 as well if requested.
6943 * WHOIS command works now in router environment, tested with two
6944 routers, two servers and two clients.
6946 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6947 in router environment (as it is almost equivalent to WHOIS) but
6948 hasn't been tested thoroughly. Added new functions:
6950 silc_server_command_identify_parse
6951 silc_server_command_identify_send_reply
6952 silc_server_command_identify_from_client
6953 silc_server_command_identify_from_server
6955 * Disabled route cache adding because adding two different ID's with
6956 same IP replaces the old cache entry thus giving wrong route.
6957 The entry->router->connection is always the fastest route anyway
6958 so route cache may not be needed. Of course, new routes maybe
6959 established after receiving the ID when the entry->router->connection
6960 might not be anymore the most optimal.
6962 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6964 * Add route cache for received ID for fast routing.
6966 * Added silc_server_packet_route to route received packet on router
6967 that is not destined to us.
6969 * Renamed silc_server_get_route to silc_server_route_get.
6971 * Added id_string and id_string_len fields into SilcServer to
6972 include encoded ServerID for fast comparing without excess
6973 encoding of the ID's.
6975 * Cleaned up WHOIS command on server side. Added following static
6978 silc_server_command_whois_parse
6979 silc_server_command_whois_check
6980 silc_server_command_whois_send_reply
6981 silc_server_command_whois_from_client
6982 silc_server_command_whois_from_server
6984 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6985 arguments in command replies. All command functions should be
6986 updated to use this macro.
6988 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Minor typo fixes on command reply handling on server.
6992 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Added silc_server_command_add_to_channel internal routine to add
6995 the client to the channel after router has created the channel and
6996 sent command reply to the server.
6998 * Added generic silc_server_send_command to send any command from
7001 * Use static buffer with ID rendering instead of duplicating data.
7003 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Fixed a channel user mode bug when joining to a channel server gave
7006 everybody channel founder rights, oops.
7008 * We mark ourselves as the router of the incoming server connection
7009 if we are router ourselves. This way we can check in some packet
7010 sending functions whether it is locally connected server. For
7011 incoming router connections we put NULL.
7013 * For router sending packets locally means now always sending the
7014 packet cell wide; to local clients and local servers. For normal
7015 server sending packet locally means sending it to only local
7018 * Fixed the JOIN command to really work in router environment. If the
7019 channel is created it is always created by the router. Router is
7020 also responsible of making the initial joining to the channel,
7021 sending JOIN notify to the sending server and distributing
7022 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7023 does not exist server doesn't do anything else but forward the
7024 command to the router which performs everything.
7026 * Added silc_server_send_channel_key function to send the Channel Key
7029 * Added silc_server_create_channel_key to create new channel key. The
7030 channel key is now re-generated everytime someone joins or leaves
7031 a channel, as protocol dictates. Note: channel->key_len is the
7034 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7037 packet_receive.[ch] to separate packet sending and receiving
7038 routines. The server.[ch] now includes everything else including
7039 actual packet processing (writing and reading data) and other
7042 Renamed silc_server_private_message_send_internal to
7043 silc_server_send_private_message. The routine is still though
7044 used only to relay private messages as server does not send
7045 private messages itself.
7047 Renamed silc_server_new_channel to silc_server_create_new_channel
7048 and added new function sicl_server_new_channel that handles the
7049 incoming New Channel packet. Added also new sending function
7050 silc_server_send_new_channel to send New Channel Payload.
7052 * Added new function silc_server_notify to process incoming notify
7053 packet to the server/router. Server may then relay the notify
7054 to clients if needed.
7056 * Added new function silc_server_new_channel_user to process incoming
7057 New Channel User packet. Router will redistribute the packet and
7058 send JOIN notify to its local clients and locally connected servers
7059 if needed. Normal server will send JOIN notify to its local client
7060 on same channel when received this packet. Added also corresponding
7061 sending function silc_server_send_new_channel_user to sent the
7064 * Added boolean route argument to send_notif_to_channel and
7065 packet_send_to_channel functions to attempt to route the packet
7066 if it is TRUE and send only locally if it is FALSE.
7068 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7070 * silc_server_replace_id now broadcasts the received replace ID
7071 packet if it is not broadcast packet already. The router must
7072 broadcast to inform other routers about changed ID.
7074 * Added backpointer to server's router into SilcServer context in
7075 silcd/server_internal.h.
7077 * Fixed silc_server_packet_broadcast to send correct broadcast
7080 * The channel key is now distributed to the local client as soon
7081 as it is received from the router (in router environment) so that
7082 no other packet may be sent for the channel until client has
7085 * silc_server_remove_channel_user now broadcasts the received
7086 Remove Channel User packet if it is not broadcast packet already.
7087 The router must broadcast to inform other routers about removed
7090 * Added users field into SilcPacketContext that is a reference count
7091 of the context. One can increase the reference count by calling
7092 silc_packet_context_dup which is now changed to just increase the
7093 reference count instead of duplicating the data. The reference
7094 count is decresed by calling silc_packet_context_free that will
7095 free the data after the reference count hits zero.
7097 For now on the packet context and everything allocated into it
7098 (including the raw packet from network) must be freed by calling
7099 the new silc_packet_context_free function. Added also new function
7100 silc_packet_context_alloc that must be used now to allocate the
7101 context. This also means that if a routine is asynchronous from
7102 silc_[client/server]_packet_parse_type the packet context must
7103 be duplicated by calling silc_packet_context_dup. Otherwise it
7104 gets free'd after silc_[client/server]_packet_parse_type returns.
7105 Also, one must remember that if packet is duplicated then its
7106 reference count must be decresed by calling the free function as
7107 many times as it was duplicated.
7109 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7110 from both client and server.
7112 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Made joining to a channel working in router environment.
7116 * Cleaned up JOIN command on server side and create function
7117 silc_server_command_join_channel internal routine to make the
7120 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Changed silc_command_pending list to SilcDList. Also, added
7123 `ident' field to SilcServerCommandPending structure to identify
7124 the reply and to call correct callback.
7126 Added silc_server_command_pending_check function to replace the
7127 corresnponding macro. The silc_command_pending list is not
7130 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7131 to set identifier to previously allocated Command Payload. It
7132 is used to set identifier for command when resending Command
7135 * Added silc_command_payload_encode_payload to encode Command
7136 Payload buffer from SilcCommandPayload structure.
7138 * Added silc_argument_payload_encode_payload to encode Argument
7139 payload buffer from SilcArgumentPayload structure.
7141 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7143 * Changed WHOIS command to support router connection on server side.
7144 The whois request is always sent to router unless the server is
7145 standalone server. After server has received the reply from the
7146 router will it send the reply to the client.
7148 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7149 broadcast received broadcast packet. The function is used only
7150 by router. The broadcast packet is always sent to the router's
7153 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7154 render given ID to printable string, for log files for example.
7156 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Made basic router to router connections working. At least they
7159 can now connect to each other but nothing really works the way
7160 they are supposed - yet.
7162 * Added new initiator token to RouterConnection configuration
7163 file in silcd/serverconfig.[ch]. It is used to tell whether we
7164 are the initiator to the remote router or whether we'll expect
7165 the other end to connect.
7167 * Moved registering of listener task to silc_server_init, hence
7168 the server starts listenning as soon as it is run, even if it
7169 does not have connections to other routers. Let's see how well
7172 * Changed default connection retry timeouts for more suitable in
7175 * Removed cipher and such arguments from silc_idlist_add_client
7176 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7177 Added new function silc_idlist_add_data to add the keys and stuff
7180 * Added SilcIDListData structure and added it to SilcClientEntry
7181 and SilcServerEntry as their first field in the structure. This
7182 way we can explicitly cast the ID entries to the SilcIDListData
7183 structure and get common data for the entries. In past, we had
7184 to first check what type of connection it is and then cast it to
7185 correct ID entry type. Now, we can directly cast the opaque
7186 pointer to the SilcIDListData (no matter what ID entry it actually
7187 is) and get the data needed.
7189 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7191 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7192 in some circumstances even if threre were timeout tasks, though not
7193 IO tasks, but tasks anyway. Now fixed.
7195 * Defined SilcServerConnection structure to hold connection specific
7196 stuff about directly connected servers and routers. The definition
7197 is currently in silcd/server_internal.h. I thought about having
7198 a bit more important role fro this struct but for now it is used
7199 only when connecting to other server (or router actually).
7201 * Added connecting retry support in server when connecting to
7202 router(s). The retry feature implement exponential backoff
7203 algorithm. Also, added SilcServerParams structure to hold default
7204 parameters for server. For now, it include these retry settings
7205 and are hard coded. After server is moded to be as Silc Server
7206 Library this structure will be more important.
7208 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Changed client librarys channel->clients table to SilcList and
7211 changed code accordingly.
7213 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7215 * Changed client's channel table to SilcList and changed code
7216 accordingly. Also changed SilcChannelClientEntry to include back-
7217 pointer to the channel so that client entry can use that structure
7218 as list as well and we have fast cross-reference to the channel.
7219 This change dramatically decreased the complexity of channel
7220 handling with client entry and vice versa (removed one extra
7221 loop when searching for channel entry from many functions).
7223 * Changed server->sim from table to SilcDList and changed code
7226 * NAMES command can now be used from user interface. It will show
7227 the user list on the channel, neatly.
7229 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7230 Code now saves realname of the user if it becomes available.
7232 * Renamed configure.in to configure.in.pre and made ./prepare
7233 script to automatically add correct version string to
7234 configure.in which it creates from configure.in.pre.
7236 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * NAMES command reply now shows users mode with the nickname when
7241 * Moved silc_client_ch[u]mode[_char] functions from
7242 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7243 place sucks, they are utility functions and should be in some
7246 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7248 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7251 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Added TRQ (efficient deque and list library) into lib/trq. This is
7256 a very good list library that is currently used in the SILC. Defined
7257 SilcList API over the library because I didn't like the API very
7258 much. See lib/trq/silclist.h for the API and examples of how to
7259 use the API. Fixed various places in the code to use the new
7260 SilcList API. The SilcList is meant for lists that has a structure
7261 already defined as a list. It is not suitable to add just some
7262 context to the list (in TRQ, the context is the list actually).
7264 So, I defined SilcDList that can be used for the purpose where
7265 predefined list structure does not exit. This can be used as
7266 such list. Now some context just can be added to the SilcDList.
7267 Currently this list is not used in the SILC just yet, though there
7268 are a lot places where this can replace dynamically allocated
7269 tables and I will fix these places, later, to use SilcDList.
7270 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7271 and use TRQ internally).
7273 Also fixed some annoying warning messages that the original TRQ
7274 code generated. Also minor changes to TRQ's Makefile.in.
7276 * Added support for querying by Client ID to both WHOIS and
7277 IDENTIFY commands into server, as required by the protocol.
7279 * Removed method function pointers from SilcBuffer structure. They
7280 weren't used to anything and just increased the context size for
7281 no good reason. This change also made silc_buffer_alloc and
7282 silc_buffer_free functions inline functions.
7284 * Disabled command flooding detection support until it's fixed so
7285 that it accepts commands in but does not execute them more than once
7288 * Added silc_net_localhost(), to return local hostname, into
7289 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7290 that must be initialized before calling silc_client_init.
7292 * Added new function: silc_server_send_notify_on_channels to send
7293 notify messages to all channels client has joined. It is assured
7294 that the message is sent only once per client.
7296 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7297 lib/silcutil/silcutil.[ch] as silc_format function. The new
7298 function is generic and is used by server as well, not only by
7299 the logging routines.
7301 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7302 the provided version string was not acceptable. Added new function:
7303 silc_ske_check_version into lib/silcske/silcske.h. The function
7304 must be implemented by the application (client or server) and it
7305 does not reside in the SKE library. The function checks the version
7306 string remote end sent.
7308 * Added back pointers (to opaque context and to SilcSocketConnection)
7309 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7311 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7312 duplicate packet context structure.
7314 * Changed `notify' client operation to send same arguments as client
7315 receives from server except for ID's. ID's are mapped to correct
7316 ID entry and that is returned. Also, if channel entry is not sent
7317 by server but the notify is for channel the channel entry is sent
7318 to application (otherwise application doesn't know that it is for
7319 channel (library gets it from packet's Destination ID)).
7321 * Added silc_client_remove_from_channels into client library to
7322 remove a client from all channels it has joined to. Used when
7323 received SIGNOFF notify from server. Added also new function
7324 silc_client_replace_from_channels to replace old ID entry with
7325 new ID entry on all channels. Used when received NICK_CHANGE
7328 * Fixed ID Cache list handling in silc_idlist_get_client in
7329 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7330 to get (or query) client by ID.
7332 * Updated TODO list.
7334 * Added connection authentication status message defined by the
7335 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7336 support for these into the code in client and server side.
7338 * Added generic function silc_client_send_command to send any command
7339 with variable argument list. Application should use this function
7340 to send commands if the command functions provided by the library
7341 does not suite for the application's user interface needs.
7343 * Added new `failure' client operation. Application is notified about
7344 received failure packet if client is executing a protocol. In this
7345 case the protocol's execution has failed.
7347 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7348 is required by the protocol.
7350 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7351 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7354 * Added status flag to SilcSKE object to indicate realtime status
7355 of the SKE protocol.
7357 * Application receives now exactly same command reply arguments as
7358 the library receives from server. However, if ID is received the
7359 corresponding ID entry is returned to the application (eg. Client
7360 ID is mapped to correct SilcClientEntry entry and that is returned).
7361 Changed command_reply client operation due to this change.
7363 * Changed all ID's in commands and in command replys as ID Payloads.
7364 Change affected both client and server side codes.
7366 All ID's sent in SILC network (with execption of ID's in SILC
7367 Packet header) are sent in ID Payload to support variable length
7370 * Server now notifies nick changes and notifies all clients on
7371 the channels about the new nickname (about the new Client ID,
7374 * Implemented CMODE command to change channel modes. Supports all
7375 channel modes defined by the protocol specs except ban and invite
7376 lists. (Also, private channel key mode is supported but support for
7377 setting private channel key in client is missing, thus, this mode
7378 has no effect on client side (except that server requires that the
7379 client uses private channel key and normal channel traffic does not
7382 Also, invite mode works per se, but INVITE command does not work
7383 yet correctly, so you can set channel as invite only channel but
7384 inviting clients to the channel does not work (it is yet to be
7385 thought what's the best way to do it).
7387 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7388 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7389 Implemented CUMODE command to change user's mode on the channel.
7390 Supports all modes defined by the protocol specs.
7392 * Added NAMES command reply to return users modes on the channel.
7394 * Removed unnecessary and slow ciphers from lib/silccrypt.
7396 * Set SO_KEEPALIVE option to connection sockets by default.
7398 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7400 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7401 redefined the Notify Payload into protocol specs.
7403 * Added silc_id_payload_parse_id to get ID directly from raw
7406 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7408 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7409 accept searching by Client ID as well.
7411 * Added support for LEAVE and SIGNOFF notify types in client library.
7413 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7414 to parse ID Payload from raw data.
7416 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Added flags parameter into silc_ske_assemble_security_properties
7419 function in lib/silcske/silcske.[ch].
7421 * Changed notify client operation to fit better for notify messages
7422 sent by server. The notify payload received from server is now
7423 passed to the application (after parsing it to SilcNotifyPayload).
7424 It is application's responsibility to retrieve the arguments
7425 from the payload and show the message the way it wants. The message
7426 sent by server is implementation specific.
7428 * Changed public keys to comply with the protocol specification.
7429 Old public keys are not supported anymore and are not compatible.
7431 * Removed nickname from Channel Payload as the latest draft removed
7432 it. The client must resolve the nickname from the NAMES command
7433 reply received when it joined the channel.
7435 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7437 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Fixed some errors in protocol specification drafts.
7441 * Created lib/silccore/silcnotify.c to implement Notify Payload
7442 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7443 generic payloads described by protocol specifications. The file
7444 includes implementations for ID Payload and Argument Payload.
7446 * Changed Command Payload implementation to use the new Argument
7447 Payload. Changed command_xxxx_payload to command_payload_xxxx
7448 to comply with SILC coding conventions.
7450 * Added suppport for Argument Payload handling in Notify Payload
7451 implementation as protocol requires it. Added the new support
7452 into server and client lib as well.
7454 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7456 * Added support for multiple nicknames on same channel. [n] is
7457 added locally to the nickname if there are more than one same
7458 nicknames on the channel.
7460 * Server now sends all nicknames that matched WHOIS request.
7461 Client also shows the list received from server.
7463 * Added TOPIC command to client side. User can now set and show
7464 current topic on channel.
7466 * Added MOTD command to client and server. Also, server sends the
7467 motd when client connects to the server.
7469 * Changed version strings to comply ISO 8601.
7471 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Fixed protocol error handling in client library. It should now
7474 cope even if the SKE fails for some reason.
7476 * Made new protocol specification drafts for submitting to IETF.
7478 * Implemented TOPIC command to server in silcd/command.c.
7480 * Added two new notify types into lib/silccore/silcnotify.h:
7481 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7482 notify nickname change and topic setting/change on a channel.
7484 * API change of command_reply operation in client library. The
7485 application gets now the status type received from server as well.
7487 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7491 * Cras fixed and optimized the packet handling even further and
7492 it should work now. Minor change to the prototype of function
7493 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7495 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Added new function into lib/silcutil/silcschedule.[ch]:
7498 silc_schedule_with_fd to select() a specified fd. The function
7499 returns after timeout expires or data arrives or goes. The
7500 function is used by packet routines to wait that all data is
7501 received from network.
7503 * Fixed data reading from network in lib/silccore/silcpacket.c.
7504 The code now assures that all data is read from the fd and then
7505 continues packet processing. This was a bug fix since the code
7506 used to drop some data in some circumstances.
7508 * Added new function into lib/silcclient/client.[ch]:
7509 silc_client_start_key_exchange to start key exchange after
7510 connection has been established to server. The code internally
7511 now uses this funtion but its main purpose was to provide it
7512 for applications that perform their own connecting. After
7513 application has created a connection it merely calls this
7514 function to start the key exchange between client and server.
7515 The library takes care of everything else after that.
7517 Updated also lib/silcclient/README to explain the usage of
7520 * Do not send to application information that connection has
7521 been established. Application gets notified it by connect
7524 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Applied cras's patch to add silc_schedule_one function. The
7527 function runs scheduler once and returns.
7529 * Fixed the scheduler after cras messed it up. The timeout
7530 handling works now as it's supposed to work.
7532 * Added into lib/silccore/ silcnotify.h to include notify
7533 message types support. Changed silc_server_send_notify*
7534 functions, in server.[ch], to support those new notify types.
7535 Added the support for the notify types into client library,
7536 as well. Added new notify client operation into ops.h in
7539 * Changed silc_server_packet_send_to_channel to send normal
7540 packets instead of just channel message packets. The function
7541 is now used to send the notify packets to channels. It is not
7542 used to send channel message packets anymore, as server never
7545 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7546 va_arg()s as it seems to require it nowadays. I guess, if SILC
7547 is compiled with older va_arg() the new code should work anyway.
7549 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7551 * Splitted core library. Core library (lib/silccore) includes
7552 now only SILC protocol specific core (and common) components.
7553 Created new utility library (lib/silcutil) that includes more
7554 generic purpose stuff. The stuff for util library was taken
7555 from the old core library. This was minor and easy split.
7557 * Created SILC Client Library (lib/silcclient) that includes
7558 implementation of the SILC client without user interface. This
7559 was major move from silc/ directory. The code has been changed
7560 so that it is transparent towards the user interface. The
7561 silc/ directory includes now the same user interface as before
7562 and it uses the new client library. Read lib/silcclient/README.
7563 Basicly, the client library performs everything else related
7564 to SILC except user interface handling. Also, configuration
7565 files are considered to be part of user interface and library
7566 does not handle them.
7568 This change also changed a lot of structures, function naming etc.
7569 Most important change was that SilcClientWindow object was
7570 renamed to SilcClientConnection in the client library. Created
7571 also new file lib/silcclient/ops.h. Also added new files
7572 silc/local_command.[ch] and silc/client_ops.[ch].
7574 All these changes were made to make it easier for user interface
7575 designers to create what ever user interface for the SILC client
7578 It is also expected that the server will be moved to lib
7579 directory as well and SILC Server Library will be created;
7580 sometimes in the future.
7582 * Removed Local commands from lib/silccore/silccommand.h as
7583 they are application specific and new client library does not
7584 handle any of those anymore.
7586 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7587 old client implementation in silc/.
7589 * Added support for callback functions in SILC_LOG_* macros.
7590 Application can now set its own callbacks that will be called
7591 instead of using the default functions that will always print
7592 the debug messages to stderr (or stdout). Also, debugging can
7593 now be disabled by setting silc_debug to FALSE and re-enabled by
7594 setting it to TRUE. Note, that logging will still work even
7595 if debugging is disabled.
7597 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7598 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7599 silc_log_reset_debug_callbacks.
7601 * To enable debugging in silc client one must give now -d
7602 option on command line.
7604 * Changed silc_schedule_init to automatically allocate task queues
7605 if they are not allocated before calling it.
7607 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * Added GMP 3.1 into math library.
7611 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7614 a channel in SILC network. The packet is used by servers and
7615 routers to notify other routers that user has left a channel.
7616 This little feature was missing until now. Added the feature
7617 to protocol specification as well.
7619 Added functions: silc_server_send_remove_channel_user and
7620 silc_server_remove_channel_user into server.[ch].
7622 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7623 lib/silccore/silcpacket.h. However, they are not implemented
7626 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Fixed joining to a channel and sending channel messages
7629 between server and router. The channel message sending should
7630 now work inside a cell.
7632 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Fixed the private message sending between server and router.
7635 The private message sending should now work inside a cell.
7637 * Added silc_server_replace_id into server.[ch] to replace
7638 existing ID in the SILC network.
7640 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7641 and silc_idlist_replace_server_id into idlist.[ch] in server.
7643 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * Fixed the server to server connections. Server can again now
7646 connect to router. Router to router connections probably does
7649 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7651 * Added dynamic protocol registering support. Now protocols can
7652 registered and unregistered on the fly. Patch by cras.
7654 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7656 * Added lib/contrib directory to hold routines that some platforms
7657 don't have but are needed by SILC.
7659 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7660 into lin/contrib to provide getopt() and getopt_long() for
7661 those who don't have it.
7663 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7665 * Added AWAY command to client. When away message is set and
7666 client receives a private message packet the client automatically
7667 replies to the sender with the away message.
7669 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7670 bug seemed to be the cause of recent problems when compiling
7673 * Added version detection support to SKE protocol specification
7674 and added the new changes to the SKE implementation as well.
7675 There were other minor changes in the SKE protocol as well.
7677 Many changes in lib/silcske/silcske.[ch] and in
7678 lib/silcske/payload.[ch].
7680 * Added ^U functionality, clear input line. Patch from cras.
7682 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7684 * Mainly small bugfixes on core library. Fixed some debugging
7685 logging and buffer overflow in silclog.c.
7687 * Updated config.sub and config.guess on the distribution tree.
7689 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Added command lagging support in server. Client may execute
7692 commands now only once in two seconds.
7694 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Optimized packet reception. MAC computation and checking is now
7697 also more optimized. A lot previously duplicated code is now
7698 used as generic by both client and server.
7700 * Fixed key pair generation in clientutil.c
7702 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7704 * Added into lib/silccore/silcbufutil.[ch] new function;
7705 silc_buffer_realloc.
7707 * Moved generic packet sending/encryption functions to
7708 lib/silccore/silcpacket.[ch] from client and server. Some
7709 rewriting of the functions.
7711 * Moved all generic packet reception/decryption functions to
7712 lib/silccore/silcpacket.[ch] from client and server. The
7713 packet processing is now much cleaner in both client and server.
7714 These were major changes in both client and server.
7716 * Created many common functions in server to do packet sending.
7717 Previously code were duplicated a lot, this has been removed
7720 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7722 * Rewrote major parts of the ID cache system. Don't know
7723 whether it is better now or not but at least the API is more
7726 * Major rewrite on ID cache stuff on client because of the ID
7727 cache API changes. Added idlist.c to client.
7729 * Also major rewrite on ID cache stuff on server as well.
7730 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7731 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7732 in hand, instead they are all put into the ID cache system now.
7733 All server_idlist_* routines uses ID cache now instead of
7734 traversing its own lists (those lists does not exist anymore).
7735 SilcIDList though still exists. Also, SilcXXXEntry's are
7738 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Finally made the SKE implementation compliant to the protocol
7741 specification. All mp integers are now binary encoded as
7742 opposed being HEX encoded.
7744 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7747 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7748 functions: silc_[encode/decode]_pem. Also added function
7749 silc_encode_pem_file to PEM encode with newlines ('\n') for
7752 * SILC public keys are now encoded either PEM or binary. Same
7753 option is for private keys as well. By default private keys
7754 are binary encoded and public keys PEM encoded. Silly HEX
7755 encoding were removed.
7757 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7758 function to create fingerprints.
7760 * Fixed a bug in SHA1; does not change the original data anymore.
7762 * Partly implemented INFO command on client and server side.
7763 Fixed CLEAR command. Changes to SERVER command; show current
7764 server(s) when giving command without arguments. Added
7765 VERSION command to client.
7767 * Added check to server that unregistered connections cannot
7768 execute commands (unless it is specificly allowed).
7770 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * Fixed screen refresh.
7774 * Fixed channel joining bug from client. On some circumstances
7775 client tried to join to a channel it had already joined.
7777 * Added public key verification process into client's protocol.c.
7778 The client now verifies the public key from user and saves
7779 it into ~./silc/serverkeys/ directory.
7781 Added into: clientutil.[ch]: silc_client_verify_server_key.
7783 * Changed SKE protocol's silc_ske_initiator_finish function
7784 to accept callback function that verifies the received public
7785 key. Removed old silc_ske_verify_public_key function.
7787 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7789 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7790 silc_pkcs_private_key[_data]_set.
7792 * Made the password and public authentication more cleaner in
7793 server's protocol.c.
7795 * Removed historic and obsolete protocol `channel_auth' from
7796 both client and server.
7798 * Removed wrong way of sending command status messages from
7799 server to client in server's command.c. The old way violated
7800 protocol specification.
7802 Changes to silccore/silccommand.[ch]: removed
7803 silc_command_encode_status_payload -> not needed anymore,
7804 changed silc_command_encode_payload_va to accept extra
7805 argument on variable argument list. The argument type must
7806 now be provided to the function. Also, added new function:
7807 silc_command_encode_reply_payload_va which is same as
7808 normal command_encode_payload_va except command status type
7809 is provided as extra argument.
7811 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7813 * Added ~./silc directory handling. The directory includes the
7814 public and private keys for the client.
7816 Added silc_client_check_silc_dir, silc_client_create_identifier
7817 and silc_client_load_keys.
7819 * Implemented SILC protocol compliant public key. Added public
7820 and private key saving to and loading from files.
7822 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7823 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7824 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7825 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7826 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7828 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7829 silc_pkcs_load_[public/private]_key.
7831 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7833 * Added silc_server_get_route (route.[ch]) to get connection
7834 data for the fastest route for given ID.
7836 * Implemented INVITE command on client and server. The command
7837 were re-defined in the SILC Protocol Specification and the
7838 implementation now complies with the specification.
7840 * Implemented PING command on client and server.
7842 * Implemented NAMES command on client and server. The server side
7843 supports currently only normal server not router server yet.
7844 Some changes to NAMES definition in SILC protocol specification.
7846 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Implemented LEAVE command on client and server.
7850 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7851 again. This change was made to the protocol as well. Server
7852 should not violate the protocol specification anymore.
7854 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7857 was tested. SOCKS4 was not but should work anyway.
