3 * ROBOdoc documented lib/silcutil/silcutil.h.
5 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
7 * Optimized even more the SilcPacketContext structure. Now
8 totally saved 16 bytes of memory per context after optimization.
9 Affected files are lib/silccore/silcpacket.[ch].
11 * Made strict checks for valid SILC IDs. Affected file is
12 lib/silccore/silcid.c.
14 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
16 * Changed the object argument for silc_cipher_register,
17 silc_hash_register, silc_hmac_register and silc_pkcs_register
18 to const. Affected files are lib/silccrypt/silccipher.[ch],
19 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
21 * Changed the silc_get_username and silc_get_real_name to
22 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
24 * Fixed the Irssi SILC Client to use the silc_get_username and
25 silc_get_real_name insted of glib routines since the glib
26 routines only corrupt stack. Fixes the Irssi SILC to work in
27 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
29 * Fixed the Irssi to not use g_get_home_dir since it crashes
30 or returns garbage on cygwin and corrupts stack. Added function
31 get_home_dir to Irssi routines. Affected files are
32 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
34 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
36 * Made some structure optimizations. SFTP memory FS MemFSEntry
37 entry structure. Optimized SilcTask structure. Optimized
38 SilcPacketContext structure.
40 Affected files lib/silcsftp/sftp_fs_memory.c,
41 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
43 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
45 * And yet again reverted back the config thing since Johnny
46 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
49 * Fixed memory leaks from config object. Affected files are
50 silcd/serverconfig.[ch].
52 * Added support for adding new connections to the server in rehash.
53 After rehash they take effect.
55 Added support for changing the maximum allowed connections in
56 rehash. The number can grow but going smaller is not supported.
58 Added function silc_server_num_sockets_by_remote to the
59 silcd/server_util.[ch].
61 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
63 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
65 * Added preliminary checking during config parsing for a valid
66 public/private key and removed further checks in the code.
67 Affected files are silcd/serverconfig.[ch], server.c.
69 * Moved functions silc_server_drop() and silc_server_daemonise()
70 from server.c to silcd.c since they are stricly related to
71 the application activity.
73 * Reverted a small part of the automatic ref/unref since
74 it caused a double unref in some situations. Affected
75 files are silcd/silcd.[ch], server.c, serverconfig.c.
77 * Added some .cvsignore files in the lib directory.
79 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Fixed silc_net_gethostbyaddr to correctly resolve by
82 address. Affected file lib/silcutil/silcnet.c.
84 * Fixed the notify relaying to client. The HMAC to be used
85 with relayed packets ws wrong and caused decryption failure
86 at the client end. Affected file is silcd/packet_receive.c.
88 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
90 * Created new branch silc_protocol_1_0_branch.
92 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
94 * Changed the silc_server_config_* routines to be SilcServer
95 independent. They are now officially application specific code
96 and not part of generic server implementation. Affected files
97 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
99 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Added automatic referencing of config context in the
102 silc_server_config_alloc, and automatic unreferencing in the
103 silc_server_config_destroy. Affected files are
104 silcd/serverconfig.[ch], silcd/silcd.c.
106 * Fixed the silc_log_quick handling in the logging routines.
107 It didn't log quickly when it was TRUE. Affected file is
108 lib/silcutil/silclog.c. Also the flush delay was set even
109 if it was 0 in config file. Affected file is
110 silcd/serverconfig.c.
112 * Added support for changing key pair of the server in rehash.
113 Affected file silcd/server.c.
115 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
117 * Fixed the TOPIC_SET notify to not cras. It changed the topic
118 too early, before getting the channel entry. Affected file
119 is silcd/packet_receive.c.
121 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
123 * Added functions silc_server_config_[ref/unref], these are used
124 to prevent that the config object is destroyed.
126 No longer directly affect global variables silc_log_quick and
127 silc_log_delay, they are first cached inside the config object
128 and then applied with silc_server_config_setlogfiles().
130 silc_server_config_set_defaults() is now internal to
131 serverconfig.c, there are no reasons to show this internal stuff
134 Affected files are silcd/serverconfig.[ch].
136 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
137 fprintf's to stderr, since some code may be executed again after
138 the server went into the background. Affected files are
141 * Added rehash support. Added function silc_server_rehash() that
142 will perform all the basic tasks of the rehashing procedure.
144 * Added command line option `-x, --hexdump'. This will enable the
145 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
146 The option `--hexdump' implies `--debug'.
148 * Fixed a bad bug in the logging APIs (silcutil library) where
149 the application would crash after calling silc_log_reset_all().
151 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
153 * Fixed the KICKED notify handling in client library to
154 correctly remove the channel and all entries from the
155 channel when I was kicked. This bug crashed the client.
157 Fixed yet another but in KICKED notify handling to remove
158 the kicked client correctly from the channel.
160 Affected file is lib/silcclient/client_notify.c.
162 * Fixed a minor bug in looking up correct client entry
163 in KICKED notify in server. Affected file is
164 silcd/packet_receive.c.
166 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
167 sources correctly to distribution. Fixes --with-gmp option.
169 * Removed the manual rehashing from ID Cache, and changed it
170 to use the SILC Hash Table's auto rehash feature. Affected
171 file is lib/silccore/silcidcache.c.
173 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Fixed a bug in the silc_client_nickname_format function that
176 handles the multiple same nickname formatting. Two clients
177 with same nickname caused problems after the first one left
178 and rejoined. It didn't format the nickname correctly.
179 Affected file is lib/silcclient/idlist.c.
181 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
183 * Don't change the topic if olod topic is same as new one.
184 Affected file is silcd/packet_receive.c.
186 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Added cross-reference support to the SILC Documentation
189 generator. All types across all HTML files are now cross-
190 referenced. Affected files util/robodoc/generator.c and
191 scripts/silcdoc/silcdoc.
193 * Added file lib/silcutil/silctypes.h to include all the
194 arithmetic type definitions and some macros. Removed
195 includes/bitmove.h and moved macros to silctypes.h.
197 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
199 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
201 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Added `type' argument to silc_id_payload_parse_id function which
204 now returns the type of the ID to the sent pointer. Affected
205 file is lib/silccore/silcid.[ch].
207 * Added check for CMODE_CHANGE notify type that mode change is
208 allowed by the sender. Affected file silcd/packet_receive.c.
210 * Added check for CUMODE_CHANGE notify type that mode change is
211 allowed by the sender. Affected file silcd/packet_receive.c.
212 Added the ID type as CUMODE_CHANGE notify type as argument
213 to the `notify' client operation. Affected files are
214 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
216 * Added function silc_client_add_server to the client library.
217 Added support for resolving also channel and server info when
218 received unknown entity in notify packet. Affected files are
219 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
221 * Added function silc_command_get_status to return the command
222 status from the command reply's argument payload. Affected files
223 are lib/silccore/silccommand.[ch].
225 * Added check for KICKED notify type that the kicking is
226 allowed by the client. Affected file silcd/packet_receive.c.
228 * Created function silc_get_input which can be used to get input
229 (echo on or off) from user on command line. Affected files are
230 lib/silcutil/silcutil.[ch].
232 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
234 * Optimized silc_server_packet_relay_to_channel function.
235 Added new function silc_channel_message_payload_encrypt which
236 can be called directly if channel message payload needs to
237 be encrypted and is already encoded (no need to call _encode
238 function). Packet relaying is now done by router without any
239 extra memory allocations. Affected files are
240 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
243 * Fixed the INVITE notify handling. It took wrong arguments
244 as invite list and invite delete. Affected file is
245 silcd/packet_receive.c.
247 * Added check for TOPIC_SET notify type that the topic change is
248 allowed by the client. Affected file silcd/packet_receive.c.
250 * Added check for INVITE notify type that inviting is allowed by
251 the client. Affected file silcd/packet_receive.c.
253 * Changed the silc_server_client_on_channel to return the
254 SilcChannelClientEntry as well. Moved the function
255 silc_server_check_cmode_rights to server_util.[ch].
256 Affected files are silcd/server_util.[ch], silcd/command.c.
258 * Added function silc_server_check_umode_rights to check whether
259 changing client's user mode is allowed. Added check for
260 UMODE_CHANGE notify type that the umode change is allowed
261 by the client. Affected files are silcd/server_util.[ch],
262 silcd/packet_receive.c and silcd/command.c.
264 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
266 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
267 ID length. It ignored that ID can be IPv6 based as well.
268 Affected file lib/silccore/silcpacket.h.
270 * Fixed the silc_id_id2str and silc_id_str2id to take the
271 IPv6 address offset's into consideration. Affecte file is
272 lib/silccore/silcid.c.
274 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
276 * Fixed the internal Unix scheduler functions to check for
277 NULL context they may receive. The affected file is
278 lib/silcutil/unix/silcunixschedule.c.
280 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
282 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
283 can specify different directory with --home command line
284 parameter. Affected files irssi/src/silc/core/client_ops.c,
287 * SILC-specific commands aren't now executed if the active server
288 isn't of SILC-type, so there won't be problems with having
289 IRC and SILC protocol support in same client. Affected files
290 irssi/src/silc/core/silc-channels.c, silc-servers.c,
293 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
295 * Improved the signal support in SILC Schedule. Added new
296 function silc_schedule_signal_call which is used by application
297 to mark a signal to be called. It is now safe to perform
298 any kind of tasks in signal callbacks since it is guaranteed
299 that the application specified signal callback is called
300 after the signal is over. Affected files are
301 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
303 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
305 * Added `name' field to SilcChannelPrivateKey to represent
306 application given name for the key. Moved also the context from
307 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
308 Added the `name' argument also to the function
309 silc_client_add_channel_private_key.
311 Added function silc_client_current_channel_private_key to set the
312 current channel private key in use.
314 Added "change" command to KEY command which can be used to change
315 the current channel private key. Bound the command also to
318 Also affected files lib/silcclient/client_channel.c,
319 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
321 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
323 * Added silc_rng_get_byte_fast function in to the
324 lib/silccrypt/silcrng.[ch].
326 * Changed the interface of silc_packet_assemble and the
327 silc_packet_send_prepare. If silc_packet_assmble is now
328 called the application does not call silc_packet_send_prepare
329 because the library will call it automatically. These
330 interfaces now also return a reference to the outgoing buffer
331 which includes the assembled packet, which the application can
332 use to encrypt the packet.
334 Affected files are lib/silccore/silcpacket.[ch],
335 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
336 silcd/packet_send.c, server_backup.c and packet_receive.c.
338 * Fixed a packet sending bug on very high load, where outgoing
339 packet queue wasn't handled correctly and packets got corrupted.
340 Affected files are lib/silcutil/*/silc*sockconn.c,
341 lib/silcclient/client.c and silcd/server.c.
343 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
345 * Added macro SILC_PACKET_DATALEN which can be used during
346 packet assembling to check whether the data to be added to
347 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
348 len is truncated until it fits it.
350 Added checks for maximum length of channel message payload and
351 private message payload also.
353 Added checks for maximum packet length in server and in
356 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
357 lib/silcclient/client.c, lib/silccore/silcchannel.c and
358 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
359 lib/silcclient/client_prvmsg.c.
361 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
363 * Added silc_server_packet_queue_purge call to the
364 silc_server_disconnect_remote to assure that all data in the
365 queue before disconnecting is sent to the network. Affected
368 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
370 * Added the deleting of server's own ID cache entry to the
371 silc_server_free function. Free also everything else that
372 has been allocated in silc_server_init. The affected file
375 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
377 * Added functions silc_parse_version_string, silc_version_to_num,
378 and silc_ske_parse_version to parse SILC protocol style version
379 strings. Affected files lib/silcutil/silcutil.[ch] and
380 lib/silcske/silcske.[ch].
382 * Added new configuration params: version_protocol, version_software
383 and version_software_vendor to specify what version the remote
384 host must at least be to be able to connect to server. The vendor
385 string can be regex matched too. Added new function
386 silc_server_connection_allowed to check maximum number of allowed
387 connections, and allowed versions for incoming connections.
388 Affected files are silcd/server.c, server_util.[ch] and
391 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
393 * Added preliminary support for signals in scheduler. The
394 signals we care about are now blocked always when the scheduler
395 is locked. This way we can synchronise the use of signal with
396 scheduler. It is guaranteed that when signal occurs the scheduler
397 is not locked, and thus new tasks can be safely added to the
400 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
401 to silc_schedule_internal_init and silc_schedule_internal_uninit.
402 Added new platform specific routines
403 silc_schedule_internal_signals_[un]block and
404 silc_schedule_internal_signal_[un]register.
406 Added new functions to SILC Schedule API:
407 silc_schedule_signal_[un]register. Each signal that application
408 is going to use should be registered to the scheduler.
410 Affected files are lib/silcutil/silcschedule.[ch],
411 lib/silcutil/*/silc*schedule.c.
413 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Check for unauthenticated client and server in the
416 silc_server_new_client and silc_server_new_server functions.
417 Affected file silcd/packet_receive.c.
419 * Added function silc_string_is_ascii to check whether given
420 string is 7-bit ASCII string. Affected files are
421 lib/silcutil/silcutil.[ch].
423 * Added function silc_id_is_valid_server_id into the
424 silcd/serverid.c and added checking for valid Server ID's in
425 silc_server_new_server. The Server ID must always be based
426 on the server's public IP address.
428 * Added logging of DISCONNECT packet message in the server.
429 Affected file silcd/server.c.
431 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
433 * Changed all library interfaces that use Global RNG to also
434 accept SilcRng as argument. Affected files are
435 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
436 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
437 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
438 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
441 * Added function silc_pkcs_generate_key to the
442 lib/silccrypt/silcpkcs.[ch] for applications so that they
443 don't need to do pkcs->pkcs->init calls anymore.
445 * Remove SilcSocketConnection from the SFTP API since it really
446 wasn't needed there. The application has the information
447 saved in its contexts anyway and the SFTP layer doesn't need
448 know about it. Affected files lib/silcsft/silcsftp.h and
449 lib/silcsftp/sftp_[server/client].c.
451 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
452 The SilcSimContext is not SilcSim.
454 * Fixed possible buffer overflows in silc_id_render in the
455 lib/silcutil/silcutil.c.
457 * On EPOC the global crypto module lists are not used at all
458 in the crypto library. Added support for using the constant
459 algorithm list on EPOC. Affected files are
460 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
463 * Fixed the handling of third parameter of KICKED notify, since
464 it was mistakenly updated to SILC Protocol 1.0 even though it
465 is to be included in 1.1. Since it is not in 1.0 it is not
466 mandatory, and this fix now handles it only if it is provided,
467 and it is not error if it is not provided. Affected file
468 lib/silcclient/client_notify.c.
470 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
472 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
473 client. Affected file irssi/src/silc/core/client_ops.c.
475 * Merged with Irssi 0.8.4 from irssi.org CVS.
477 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
479 * Check for valid socket connection in client entries before
480 sending any messages. Fixes a crash, but doesn't fix some
481 other underlaying bug that is lurking there. Affected
482 file silcd/packet_send.c.
484 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
486 * $usermode, $cumode and $cumode_space expandos shouldn't do
487 anything with non-SILC server records. Affected file
488 irssi/src/silc/core/silc-expandos.c
490 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
492 * Fixed the silc_net_check_[host/local]_by_sock to support
493 IPv6 bound sockets as well. Now they can return IPv6 addresses
494 as well. Affected file lib/silcutil/silcnet.c.
496 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
497 Affected lib/silcutil/unix/silcunixnet.c.
499 * Fixed ID rendering (at least on some platforms, not NetBSD)
500 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
502 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
504 * Added silc_hash_public_key and silc_hash_public_key_compare
505 functions to be used with SilcHashTable. They can be used to
506 hash public keys and compare public keys in hash table. Affected
507 file lib/silcutil/silcutil.[ch].
509 * Added support for specifying multiple public keys for Client
510 connection section in server configuration file. This makes it
511 possible to accept multiple public keys from same host, or to
512 make a section that accepts any incoming host, and have the
513 accepted public keys listed in the section.
515 Added functions silc_sever_[find/get]_public_key, added the
516 support for this actually to all connection sections but only
517 the Client section is currently allowed to specify multiple
520 Affected files are silcd/server.c, server_internal.h,
521 command.c, protocol.c, server_util.[ch], packet_receive.c.
523 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
525 * Merged Irssi 0.8.2 from irssi.org CVS.

687 Affected file lib/silcclient/client.c.
689 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
691 * ROBOdoc documented the lib/silcske/silcske.h, and improved
692 the SKE interface a bit.
694 * Fixed padding problem in PKCS#1. The padding was not actually
695 random since the random number generator was used incorrectly.
696 This security bug affects only when encrypting with PKCS#1, and
697 it is not currently used at all in SILC. SILC only use signing
698 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

779 algorithm parts and created new file silcalgs.conf, that
780 is now included from the example_silcd.conf.in.
782 * Optimized the silc_server_connect_to_router_second to take
783 the connection configuration object from the SilcServerConnection
784 object instead of finding it during the connecting phase.
785 Added the configuration object to SilcServerConnection struct.
786 Affected files silcd/server_internal.h, server.c.

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

870 * Fixed the file transfer's key agreement payload to include
871 zero port also if the hostname is NULL because it could not
874 Call file transfer monitor callback now also if error occurs
875 during key agreement protocol.
877 Changed the silc_client_file_send interface to return the
878 SilcClientFileError instead of session id. The session ID
879 is returned into pointer provided as argument.

896 file lib/silcutil/silclog.c.
898 * Fixed the channel message payload decryption in the function
899 silc_channel_message_payload_decrypt to not modify the original
900 buffer before it is verified that the message decrypted
901 correctly. Otherwise, next time it is called with correct
902 channel key it won't encrypt since the payload is corrupted.
903 Affected file lib/silccore/silcchannel.c.
905 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

919 become invalid in the callback but it was referenced after
920 the callback returned.
922 Do not allow auto rehashing of hash table during the
923 silc_hash_table_foreach operation, for same reasons as it is
924 not allowed for SilcHashTableList. Affected files are
925 lib/silcutil/silchashtable.[ch].
927 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

948 users list to SilcHashTable. The affected files are
949 lib/silcclient/idlist.[ch].
951 * Fixed a bug in hash table tarversing. While the hash table
952 is traversed with SilcHashTableList the table must not be
953 rehashed. It is now guaranteed that auto rehashable tables
954 are not rehashed while tarversing the list. Also defined that
955 silc_hash_table_rehash must not be called while tarversing
956 the table. Added function silc_hash_table_list_reset that must
957 be called after the tarversing is over. The affected files are
958 lib/silcutil/silchashtable.[ch].
960 * Changed all hash table traversing to call the new
961 silc_hash_table_list_reset in server and in client library.
963 * Added function silc_client_on_channel to return the
964 SilcChannelUser entry if the specified client entry is joined

975 lists correctly. Affected file silcd/command.c.
977 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
979 * When sending JOIN command to router for processing the
980 sender's old command identifier was not saved back to the
981 sender's command context, fixed now. The affected file is
984 * Create the key in JOIN command of the router did not return
985 the channel key, added check for this. Affected file is
988 * Fixed a channel ID update bug in JOIN command reply. Do
989 not directly upgrade the ID but call the function
990 silc_idlist_replace_channel_id if the ID was changed.
991 Affected file silcd/command_reply.c.
993 * Fixed memory leaks from command calling if it would fail.
994 Affected file silcd/command.c.

1021 functions. Affected file silcd/server.c.
1023 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1024 which ID was changed. This way the router will send the
1025 user list for the channel again, and server won't be in
1026 desync in some rare circumstances. Affected file is
1027 silcd/packet_receive.c.
1029 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1078 * Fixed the NICK command to always give the unformatted
1079 nickname to the one giving the NICK command. If unformatted
1080 nickname is cached already it will be formatted and the
1081 local entry will always get the unformatted nickname.
1082 Affected file lib/silcclient/idlist.c.
1084 * Fixed some double frees from client library commands.
1085 Affected file is lib/silcclient/command.c.
1087 * Fixed CUMODE command in server to assure that no one can
1088 change founder's mode than the founder itself, there was a
1089 little bug. Affected file silcd/command.c.
1091 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1093 * Removed the SilcClientCommandDestructor from the client
1094 libary, it is not needed anymore. Affected files are
1095 lib/silcclient/silcapi.h, command[_reply].[ch],
1096 client_notify, idlist.c.
1098 * Fixed GETKEY command to first resolve client, and then
1099 resolve the server only if the client was not found, instead
1100 of resolving both at the same time. Affected file is
1101 lib/silcclient/command.c.
1103 * Added silc_client_start_key_exchange_cb and lookup the
1104 remote hostname and IP address before starting the key
1105 exchange with server. The affected file is
1106 lib/silcclient/client.c.
1108 * The server's public key is now saved using the IP address
1109 of the server and not the servername for the filename.
1110 The hostname public key filename is checked as an fall back
1111 method if the IP address based filename is not found.
1113 Fixed the GETKEY command to save the fetched server key
1114 in correct filename.
1116 Print the remote server's hostname now when new key is
1117 received during connection process. Affected file is
1118 irssi/src/silc/core/client_ops.c.
1120 * Return always our own public key to the client if it asks
1121 for it with GETKEY command. Affected file silcd/command.c.
1123 * Removed the use_auto_addr variable from default config
1124 file since it was in wrong section. Affected file is
1127 * Fixed TOPIC_CHANGE notification to not route it when it
1128 was sent using silc_server_send_notify_to_channel function.
1129 Affected file silcd/command.c.
1131 * Fixed silc_server_send_notify_kicked to send the kicker's
1132 Client ID also, it was missing. Affected files are
1133 silcd/command.c, silcd/packet_send.[ch].
1135 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1137 * Do not save client history information in SERVER_SIGNOFF.
1138 Fixes the bug in normal server that it does not detect
1139 the client becoming valid after the server becomes back
1140 online. Affected file silcd/server_util.c.
1142 * Added `sock_error' field into the SilcSocketConnection
1143 context. When error occurs during socket operation (read
1144 or write) the error is saved. Added also new function
1145 silc_socket_get_error to return human readable socket error
1146 message. Affected files are lib/silcutil/silcsockconn.[ch],
1147 lib/silcutil/unix/silcunixsockconn.c, and
1148 lib/silcutil/win32/silcwin32sockconn.c.
1150 * The server now prints the socket error message in the
1151 signoff for client. Affected file silcd/server.c.
1153 * Fixed the `created' channel information sending from router
1154 to server in JOIN command. Checks now whether the channel
1155 really was created or not and set it according that.
1157 Fixed the JOIN command to use the client entry's current
1158 ID during the joining procedure instead of the one it sent
1159 in the command (it is checked though), since it can change
1160 between the packet processing and command processing, and
1161 would just case unnecessary pain in the client end. Affected
1162 file silcd/command.c.
1164 * Fixed a channel key payload sending to use correct channel
1165 ID when the server was forced to change the channel's ID by
1166 router. Router sent the key payload with the old Channel ID.
1167 Affected file silcd/packet_receive.c.
1169 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1171 * Call silc_server_save_channel_key only if the key payload
1172 was provided in the JOIN command's command reply. Affected
1173 file silcd/command_reply.c.
1175 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1177 * Fixed silc_mp_sizeinbase to return the value correctly with
1178 MPI. Affected file lib/silcmath/mp_mpi.c.
1180 * Fixed the stop_server signal to correctly stop the scheduler
1181 and gracefully stop the server when SIGTERM or SIGINT signals
1182 are received. Affected file silcd/silcd.c.
1184 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1186 * Simple handling of TERM and HUP signals. Also added some log
1187 flushing call around. Affected file is
1190 * Fixed small bugs in silclog.c. Now buffering output will take
1191 effect after 10 seconds since startup: This will ensure that
1192 no important startup messages are lost. Also output redirection
1193 will preserve original format ([Date] [Type] message).
1194 Affected file is lib/silcutil/silclog.c.
1196 * Added two options to the config file, in the logging section:
1197 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1198 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1200 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1202 * Do not print the warning about log files not being initialized
1203 more than once to avoid excess logging. Affected file is
1204 lib/silcutil/silclog.c.
1206 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1207 the SIM copying in make install in Makefile.am.pre.
1209 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1211 * Rewritten silclog APIs. Globally interesting changes follows:
1212 silc_log_set_files() changed to silc_log_set_file().
1213 silc_log_set_callbacks() changed to silc_log_set_callback().
1214 ROBOdoc documented silclog header file.
1215 SilcLogCb now returns bool to wether inihibit the default
1216 handler or not (to keep the old behaviour return always TRUE).
1217 The new APIs should also fix the problem of the
1218 silcd_error.log file that was written in the current directory.
1221 Log files streams will remain opened after silc_log_set_file()
1222 call, means less CPU usage notably on high traffic servers.
1223 File streams are now full buffered, and flushed to the disk
1224 every 5 minutes, lesses HD activity and CPU usage.
1225 Messages can be redirected, allowing admins to configure
1226 one single logfile for all server messages.
1227 the silc_log_quick global variable to activate fast-logging.
1228 Affected files lib/silcutil/silclog.[ch]
1230 * Changed some code to conform new silclog APIs. Affected
1231 files are doc/example_silcd.conf.in, silcd/server.c
1232 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1235 * Fixed a memory leak that could occur in some situations.
1236 Affected file silcd/serverconfig.c.
1238 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1240 * Added the silc_client_del_client to remove the client from
1241 all channels as well. Affected file lib/silcclient/idlist.c.
1243 * Fixed the client library to correctly remove the client
1244 from all channels when the client entry is being destroyed.
1245 Affected file lib/silcclient/client_notify.c, command.c.
1247 * Added auto-nicking support to the client library. If the
1248 applicatio now sets client->nickname it will be sent to the
1249 server after connecting by the library. This way for example
1250 SILCNICK (or IRCNICK) environment variables will have effect
1251 and always change the nickname automatically to whatever
1252 it is wanted. Affected file lib/silcclient/client.[ch].
1254 * Renamed silc_server_command_bad_chars to the
1255 silc_server_name_bad_chars and moved it to the
1256 silcd/server_util.[ch]. Added also new function
1257 silc_server_name_modify_bad to return nickname that
1258 includes bad characters as new nickname without those
1259 bad characters. This check and modify is now used in
1260 silc_server_new_client when the username is initially set
1261 as nickname, so it must be checked to be valid nickname.
1262 Affected file silcd/packet_receive.c.
1264 * The nickname length is now taken from the packet for real
1265 and not trusted to strlen() since it clearly can return
1266 wrong length for nickname including bad characters. This
1267 also applies to channel names. Affected file silcd/command.c.
1269 * Removed the lib/silcsilm/modules directory. Modules are now
1270 compiled into the lib/silcsim. Fixed the copying of the
1271 modules to follow symbolic links in Makefile.am.pre.
1273 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1275 * Fixed silc_string_regexify list creation. Fixes bugs with
1276 BAN and INVITE commands in server. The affected file is
1277 lib/silcutil/unix/silcunixutil.c.
1279 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1281 * Removed the command destructor entirely from the server's
1282 command and command reply routines. It is not needed, and
1283 its usage was buggy and caused crashes. Affected files are
1284 silcd/command[_reply].[ch].
1286 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Cancel protocol and NULL sock->protocol if timeout
1289 occurred during protocol. Affected file silcd/server.c.
1291 * Cancel protocol timeouts always before calling the final
1292 callback, to assure that after final callback is called
1293 no other state will be called for the protocol anymore.
1294 Affected file silcd/protocol.c.
1296 * Print error log if incoming connection configuration could
1297 not be found. Affected file silcd/server.c.
1299 * Fixed JOIN command to correctly save the founder mode
1300 to the client on normal SILC server, when the channel
1301 was created by the router. Affected file silcd/command.c.
1303 * Fixed LIST command (hopefully) to send correct reply
1304 packets. Affected file silcd/command.c.
1306 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * The silc_packet_receive_process now returns FALSE if the
1309 read data was invalid packet, and TRUE if it was ok.
1311 The server now checks that if unauthenticated connection
1312 sends data and its processing fails the server will close
1313 the connection since it could be a malicious flooder.
1315 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1317 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Make sure the warning about error opening a log file is
1320 printed only once and not everytime it fails (produces
1321 too much useless log). Affected file lib/silcutil/silclog.c.
1323 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1325 * Made the silc_server_daemonise() function more readable.
1326 Affected file silcd/server.c.
1328 * Pid file is now optional, the user may comment it out from
1329 the config file. Removed define SILC_SERVER_PID_FILE, we
1330 don't need a default any longer. Affected file
1331 configure.in.pre, lib/Makefile.am.pre.
1333 * Make some use of the pid file. The server now dies at startup
1334 if it detects a valid pid file on his path. The server would
1335 die anyway in this circumstance, because of the bind() failure.
1336 Affected file silcd/silcd.c.
1338 * No longer compiling lib/dotconf.
1340 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Fixed JOIN command parsing not to crash. Affected file
1343 lib/silcclient/command.c.
1345 * Fied the NICK_CHANGE notify to add the new client entry
1346 even it is resolved. This removes an <[unknown]> nick
1347 thingy bug in the client. Affected file is
1348 lib/silcclient/client_notify.c.
1350 * Do not try to allocate 0 bytes (efence does not like it)
1351 in lib/silccore/silccomand.c when encoding payload.
1353 * Do not take IRCNICK as nickname in Irssi SILC client since
1354 it is not possible to set nickname before hand connecting
1355 the server (TODO has an entry about adding auto-nicking
1358 * Changed the silc_server_command_pending to check whether
1359 there already exists an pending entry with the specified
1360 command, command identifier and pending callback. This is
1361 to fix IDENTIFY and WHOIS related crashes that may register
1362 multiple pending commands with same identifier. Affected
1363 file silcd/command.c.
1365 * Fixed the server to reconnect to the router even if it
1366 was already reconnecting and EOF was received. This to
1367 fix a possibility that the server wouldn't ever try to
1368 auto-reconnect to the router. Affected file silcd/server.c.
1370 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Fixed the server's password authentication to use the
1373 length of the locally saved password, and not the one
1374 sent in the packet. Affected file silcd/protocol.c.
1376 * Fixed same password authentication problem in the
1377 Authentication Payload handling routines in
1378 lib/silccore/silcauth.c.
1380 * Yet another password authentication problem fixed with
1381 channel password handling in silcd/command.c.
1383 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * If first character of string in silc_parse_userfqdn is '@'
1386 then do not parse it. Affected file is
1387 lib/silcutil/silcutil.c.
1389 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Fixed minor bug in IDENTIFY command reply sending, which
1392 caused various weird problems during JOIN when it was
1393 resolving names for users. Affected file silcd/command.c.
1395 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1397 * Fixed the IDENTIFY command reply sending to chech better valid
1398 clients. It was possible to send incomplete list of replies.
1399 Affected file silcd/command.c.
1401 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * Added silc_client_command[s]_[un]register functions now to
1404 dynamically register the commands in client library. Removed
1405 the static table of commands. This allows the client library
1406 to call commands without causing the application to know about
1407 what commands library has called.
1409 Removed the INFO command reply kludge to detect when the command
1410 was called by library. Now library use its own command reply
1411 function for INFO command.
1413 Added function silc_client_command_call to call a command.
1414 Application can use it to call command, not access the structure
1417 Now all commands that are sent by the client library (not
1418 explicitly sent by application) use own command reply functions.
1420 Affected files around lib/silcclient/ and in
1421 irssi/src/silc/core/.
1423 * Fixed the WHOIS command reply sending to chech better valid
1424 clients. It was possible to send incomplete list of replies.
1426 Fixed the WHOIS and IDENTIFY to send the request to router
1427 if normal server did not do it and did not find any results.
1429 Affected file silcd/command.c.
1431 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Moved the internal data from SilcClient context into its
1434 own file, not accesible to application. Affected files
1435 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1436 and other files in client library.
1438 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Added doc/examples installation target in Makefile.am.pre.
1443 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1446 commands the found client entry will be removed from the
1447 cache, after notifying application about the error. Affected
1448 file lib/silcclient/command_reply.c.
1450 * Changed the /MSG to check for exact nickname user gave, and
1451 not let `nick' match `nick@host' if it is only one found. Now,
1452 user must type the exact nickname (like nick@host2) even if
1453 there are no more than one same nicks found. This is to avoid
1454 a possibility of sending nickname to wrong nickname since
1455 `nick' could match `nick@host'. Affected file is
1456 irssi/src/core/silc-servers.c.
1458 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Do not print "you are now server operator" or similar when
1461 giving /away command. Affected files are
1462 irssi/src/silc/core/client_ops.c, silc-servers.h.
1464 * Made the silc_server_command_pending_error_check to send
1465 the same command reply payload it received back to the
1466 original sender of the command. This way all arguments
1467 that was received by the server will be received by the
1468 client too. Affected file silcd/command.c.
1470 * Added the silc_idcache_add to return the created cache entry
1471 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1473 * Add global clients to expire if they are not on any channel.
1474 This is because normal server will never know if they signoff
1475 if they are not on any channel. The cache expiry will take
1476 case of these entries. This is done by normal servers only.
1477 The affected files are silcd/command_reply.c,
1478 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1480 * If server receives invalid ID notification for WHOIS or
1481 IDENTIFY and the ID exists in the lists, it is removed.
1482 Affected file silcd/command_reply.c.
1484 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1485 in client then client entry that it matches is searched and
1486 the nickname is printed on the screen for user. Affected
1487 file irssi/src/silc/core/client_ops.c.
1489 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Use cache entry expire time in the LIST command reply to
1492 purge old entries from the cache after the LIST command
1493 reply has been received. This way we don't have non-existent
1494 entries in the cache for too long. Affected file is
1495 silcd/command_reply.c.
1497 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * If we are normal server, and we've not resolved client info
1500 in WHOIS or IDENTIFY from router, and it is global client,
1501 we'll check whether it is on some channel. If it is not
1502 then we cannot be sure about its validity and will resolve it
1503 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1504 file silcd/command.c.
1506 * Search channel by name (if possible) rather than by ID
1507 in IDENTIFY command's command reply. Affected file is
1508 silcd/command_reply.c.
1510 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1513 Updated specs and implemented it. Affected file silcd/command.c,
1514 silcd/packet_send.c and silcd/packet_receive.c.
1516 * Implemented the <founder auth> payload handling in the JOIN
1517 command. If provided all conditions for channel joining
1518 except requirement to provide correct passphrase can be
1519 overrided by the channel founder. Updated the protocol specs.
1520 Affected file silcd/command.c.
1522 Added support for founder auth in JOIN command in client
1523 library. Fixed the parsing of the JOIN command now to support
1524 all options as they should be. The affected file is
1525 lib/silcclient/command.c.
1527 * Optimized the WHOIS and IDENTIFY commands to send the request
1528 to router only if it includes nicknames or other names. If
1529 they include only IDs then check the local cache first before
1530 routing. Affected file is silcd/command.c.
1532 * Added channels topic announcements. Affected file is
1533 silcd/packet_receive.c and silcd/server.c.
1535 * Fixed the silc_server_send_notify_topic_set to really destine
1536 the packet to channel. Affected file silcd/packet_send.c.
1538 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1539 library. Affected file lib/silcclient/client_notify.c.
1541 * Added UMODE announcements. Affected file silcd/server.c.
1543 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Memory leak fixes in:
1547 lib/silcutil/silcsockconn.c
1548 lib/silcske/silcske.c
1549 lib/silcske/groups.c
1551 lib/silccrypt/silcpkcs.c
1552 lib/silccore/silccommand.c
1553 lib/silccore/silcidcache.c
1558 * ROBOdoc documented the lib/silcske/groups.h file and a
1559 bit changed the interface for better.
1561 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1563 * Update the client entry context in the ID cache after
1564 nick change. Affected file lib/silcclient/command.c.
1565 Fixes the CUMODE command when regaining founder privileges,
1566 and a little WHOIS problem.
1568 * Fixed silc_net_gethostbyname to correctly call the
1569 inet_ntop. Affected file lib/silcutil/silcnet.c.
1571 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1573 * Added IPv6 support checking to the configure.in.pre, added
1574 also --enable-ipv6 option to override the check. Affected
1575 file configure.in.pre.
1577 * The silc_thread_create now calls the start function
1578 directly if threads support is not compiled in. Removes
1579 ugly #ifdef's from generic code. Affected files are
1580 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1582 * Added silc_net_gethostby[name/addr]_async to asynchronously
1583 resolve. Affected files are lib/silcutil/silcnet.[ch].
1585 * Added support for rendering IPv6 based server, client and
1586 channel IDs. Affected file lib/silcutil/silcutil.c.
1588 * Added support for creating IPv6 based server IDs. Affected
1589 file is silcd/serverid.c.
1591 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1593 * Added silc_net_gethostby[addr/name] into the
1594 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1595 routines. Added silc_net_is_ip[4/6]. Affected file is
1596 lib/silcutil/unix/silcunixnet.c. All routines that take
1597 address as argument now supports both IPv4 and IPv6 addresses.
1599 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1601 * Fixed LIST command reply sending in server. Affected file
1604 * Server now sends the kicker's client ID in the KICK notify
1605 to the kicked client. Affected file silcd/command.c.
1607 * The client library now parses the kickers client ID and
1608 UI displays it. Affected files lib/silcclient/client_notify.c
1609 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1611 * Made all payload parsing function prototypes consistent.
1612 They all take now const unsigned char * and uint32 pair as
1613 the payload data instead of SilcBuffer. Changes all around
1614 the source tree. Other unsigned char* -> const unsigned char*
1615 changes around the tree as well.
1617 * Optimized SFTP client and server packet sending not to
1618 allocate new buffer for each packet but to recycle the
1619 first allocated buffer. Affected files are
1620 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1622 * Optimized the SFTP client to use SilcList instead of
1623 SilcDList for requests, because it is faster. Affected file
1624 is lib/silcsftp/sftp_client.c.
1626 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1627 into lib/silccore/silcid.[ch].
1629 Renamed silcpayload.[ch] into silcargument.[ch].
1631 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * If client entry is deleted with active key agreement
1634 session, abort the session.
1636 The silc_client_abort_key_agreement now calls the completion
1637 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1639 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1642 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Don't use __restrict in older GCC's. Affected file is
1645 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1647 * silc_net_localhost now attempts to reverse lookup the
1648 IP/hostname. Affected file lib/silcutil/silcnet.c.
1650 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1651 command. It can be used to gain founder privileges at
1652 the same time when joining the channel.
1654 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1655 kicker's client ID as well. Updated protocol specs.
1657 Defined that the server must send SILC_COMMAND_IDENTIFY
1658 command reply with error status to client who sent
1659 private message with invalid client ID.
1661 Updated the protocol specification.
1663 * Added silc_server_send_command_reply to send any
1664 command reply. Affected file silcd/packet_send.[ch].
1666 * Added silc_id_payload_encode_data to encode ID payload
1667 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1669 * The server now send IDENTIFY command reply with error
1670 status if client ID in private message is invalid. Affected
1671 file silcd/packet_receive.c.
1673 * Save the server key file with server's IP address in
1674 the filename instead of hostname. The affected file is
1675 irssi/src/silc/core/client_ops.c.
1677 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1682 * Added libtool support for compiling shared objects in
1683 lib/silcsim. Affected file configure.in.pre and
1684 lib/silcsim/Makefile.am. Original patch by cras.
1686 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Pid file configuration, and server's config file fixes
1689 patch by toma. Updated CREDITS file.
1691 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Fixed silc_client_channel_message to not try to decrypt
1694 the message twice if it resolved the destination client
1695 information. This could cause of dropping one channel
1696 message. Affected file lib/silcclient/client_channel.c.
1698 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1701 lib/silcclient/client.c. This function is used when the SILC
1702 Client is run under some other scheduler, or event loop or
1703 main loop. On GUI applications, for example this may be
1704 desired to used to run the client under the GUI application's
1705 main loop. Typically the GUI application would register an
1706 idle task that calls this function multiple times in a second
1707 to quickly process the SILC specific data.
1709 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1711 * Fixed silc_server_drop() for dropping the supplementary
1712 groups as well, this could cause a security hole on some
1715 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1717 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1720 * Write PID file after dropping privileges. Added -F option
1721 to run server on foreground. A patch by debolaz.
1722 Affected files silcd/server.c, silcd/silcd.c.
1724 * Fixed MOTD to return the MOTD file server name. Affected
1725 file silcd/command.c.
1727 * Added INFO command reply handling to the Irssi SILC Client.
1728 Affected file irssi/src/silc/core/client_ops.c.
1730 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Fixed the silc_idcache_list_* routines to really support
1733 the dynamic list. Fixes a crash. Affected file is
1734 lib/silccore/silcidcache.c.
1736 * Fixed the LIST command reply to really call LIST command's
1737 pending callbacks. Affected file silcd/command_reply.c.
1739 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Update conn->local_entry->nickname after giving NICK
1742 command. Affected file lib/silcclient/command.c.
1744 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1746 * Added the [pid] option to the silcd configuration file
1748 Affected files: serverconfig.[ch] and silcd.c
1750 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Save fingerprint in WHOIS command reply in server.
1753 Affected file silcd/command_reply.c.
1755 * Fixed NICK commands pending callback registration.
1756 Affected file lib/silcclient/command.c.
1758 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Use ++server->cmd_ident when sending commands in server,
1761 instead of random number. Affected file silcd/command.c.
1763 * Fixed GETKEY command reply to call actually GETKEY pending
1764 command callbacks. Affected file silcd/command_reply.c.
1766 * A bit stricter check for nicknames. Check for same nickname
1767 in NICK command also. Affected file silcd/command.c.
1769 * Do not call INFO command everytime client ID changes, only
1770 during first connecting. Affected file lib/silcclient/client.c.
1772 * Set the new nickname only after successful command reply for
1773 NICK command is returned by server. Affected file
1774 lib/silcclient/command.c.
1776 * Remove nicknames from nicklist during server_signoff notify.
1777 Should fix /NAMES bit more. The affected file is
1778 irssi/src/silc/core/silc-channels.c.
1780 * Added `fingerprint' field to the SilcIDListData in the
1781 silcd/idlist.h to hold the fingerprint of the client's
1784 Send the fingerprint of the client's public key in WHOIS
1787 Affected files silcd/command.c, and silcd/idlist.[ch].
1789 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1790 create fingerprint from given data.
1792 * Show the fingerprint of the client's public key in WHOIS.
1793 Affected files irssi/src/module-formats.[ch] and
1794 irssi/src/silc/core/client_ops.c.
1796 * Format the multiple same nicknames also during JOIN and
1797 NICK_CHANGE notifys. Affected file is
1798 lib/silcclient/client_notify.c.
1800 * Do not print error on screen for invalid private message
1801 payload since it can come if someone is sending private
1802 messages with wrong key. Affected file
1803 lib/silccore/silcprivate.c.
1805 * Fixed multiple concurrent /PING crash. Affected file
1806 lib/silcclient/command.c.
1808 * Changed the wrong ID encoding. All IP addresses must be
1809 in MSB first order in encoded format. They were encoded
1810 wrong and was in LSB format. Affected files are
1811 silcd/serverid.c, lib/silcutil/silcutil.c.
1813 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1815 * Call the `connect' client operation through the scheduler
1816 in case of error. Affected file lib/silcclient/client.c.
1818 * Call the `failure' client operation even if the error
1819 occurred locally during a protocol. Affected file is
1820 lib/silcclient/protocol.c.
1822 * Added support of sending LIST command to router from normal
1823 server. This way normal server can get list of all channels
1824 in the network too. Fixed the channel list sending in the
1825 server too. Affected files are silcd/command.c, and
1826 silcd/command_reply.[ch].
1828 * Added silc_server_update_channels_by_server and
1829 silc_server_remove_channels_by_server. They are used during
1830 disconnection of primary router and in backup router protocol.
1831 Affected file silcd/server_util.[ch], silcd/server.c and
1832 silcd/server_backup.c.
1834 * Fixed channel adding to global list in IDENTIFY command
1835 reply in server. Affected file silcd/command_reply.c.
1837 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * If the incoming packet type is REKEY or REKEY_DONE process
1840 that packet always synchronously. Fixes yet another MAC
1841 failed error on slow (dialup) connections. Affected file
1842 lib/silcclient/client.c and silcd/server.c.
1844 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Call check_version SKE callback for initiator too. Affected
1847 file lib/silcske/silcske.c.
1849 * Implemented fix for security hole found in the SKE that was
1850 fixed in the specification few days back; the initiator's
1851 public key is now added to the HASH value computation.
1852 Added backwards support for the old way of doing it too, for
1853 old clients and old servers. Affected file is
1854 lib/silcske/silcske.c.
1856 * Enabled mutual authentication by default in SKE. If initiator
1857 is not providing mutual authentication the responder will
1858 force it. This will provide the proof of posession of the
1859 private key for responder. The affected files are
1860 lib/silcclient/protocol.c and silcd/protocol.c.
1862 * Do not cache anymore the server's public key during SKE.
1863 We do mutual authentication so the proof of posession of
1864 private key is done, and if the server is authenticated in
1865 conn auth protocol with public key we must have the public
1866 key already. Affected file silcd/protocol.c.
1868 * Added new global debug variable: silc_debug_hexdump. If
1869 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1870 file lib/silcutil/silclog.[ch].
1872 * Fixed compilation warning due to char * -> const char *.
1873 Affected files lib/silcutil/silcnet.h, and
1874 lib/silccore/silcauth.[ch].
1876 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Fixed CMODE command when new channel key was created. If
1879 the creation failed the old key was removed. Next time giving
1880 same command would crash the server since the old key was
1881 freed already. Affected file silcd/command.c.
1883 * Fixed the silc_server_announce_get_channels to not crash
1884 on reconnect. Affected file silcd/server.c.
1886 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Added silc_log_set_debug_string function to set a regex
1889 string to match for debug output. Only the function names,
1890 or filenames matching the given debug string is actually
1891 printed. This way it is possible to filter out those debug
1892 strings that user is not interested in.
1894 Fixed a bug in silc_string_regexify.
1896 Affected files lib/silcutil/silclog.[ch], and
1897 lib/silcutil/unix/silcunixutil.c.
1899 * Changed the -d options in both server and Irssi SILC client
1900 to take the debug string as argument. Affected files
1901 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1903 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Added silc_hash_babbleprint to create a Bubble Babble
1906 Encoded fingerprint. The encoding is developed by Antti
1907 Huima (draft-huima-babble-01.txt), and it creates human
1908 readable strings out of binary data. Affected file
1909 lib/silccrypt/silchash.[ch].
1911 * Print the babble print now in addition of fingerprint as well
1912 in Irssi SILC client. Affected files are
1913 irssi/src/fe-common/silc/module-formats.[ch],
1914 irssi/src/fe-common/silc/core/client_ops.c.
1916 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Fixed a security problem found in SKE. The initiator's
1919 public key too is now added to the HASH hash value creation
1920 which is signed by the responder to create the SIGN value.
1921 This will prevent anyone in the middle to lie to the responder
1922 about the initiator's public key. If this is done now, the
1923 man in the middle will get caught. Updated the protocol
1926 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Better installation directory handling. Configure module
1929 paths and other paths automatically to example_silc* files
1930 in doc/. A patch by toma.
1932 * Fixed compiler warning from MPI library, and from SILC RNG.
1935 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1936 It can be configured with ./configure. A patch by toma.
1938 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Find correct make to use in prepare-clean. A patch by
1941 toma. Affected file prepare-clean.
1943 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1945 * Added irssi variables use_auto_addr, auto_bind_ip,
1946 auto_bind_port and auto_public_ip.
1948 * Changed the interface for silc_client_send_key_agreement
1949 in lib/silcclient/silcapi.h
1953 irssi/src/silc/core/silc-core.c
1955 lib/silcclient/silcapi.h
1956 irssi/src/silc/core/silc-channels.c
1957 lib/silcclient/client_keyagr.c
1960 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Added silc_pkcs_public_key_compare to compare two
1963 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1965 * Check that the client who set the founder mode on the
1966 channel is the same client that is giving the founder
1967 mode to itself. It is done by comparing the saved public
1968 key (it is saved even in the authentication is passphrase).
1969 Affected file silcd/command.c.
1971 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Do not process packet for disconnected socket connection.
1974 Affected file lib/silccore/silcpacket.c.
1976 * Process the DISCONNECT packet through scheduler in the
1977 client library. Affected file lib/silcclient/client.c.
1979 * Fixed the silc_client_packet_parse to not to increase
1980 the packet sequence number if the conn->sock and the
1981 current socket connection is not same. This can happen
1982 for example during key agreement when the conn includes
1983 multiple socket connections (listeners). Affected file
1984 lib/silcclient/client.c.
1986 * The sender of the file transfer request now provides also
1987 the pointer (listener) for the key exchange protocol. If
1988 the listener cannot be created then it sends empty key
1989 agreement and lets the receiver provide the listener.
1991 Added `local_ip' and `local_port' arguments to the
1992 silc_client_file_send. If they are provided they are used,
1993 if not then it will attempt to find local IP address, if
1994 not found or bind fails then the remote client will provide
1997 Affected files are lib/silcclient/client_ftp.c and
1998 lib/silcclient/silcapi.h.
2000 * Extended the FILE SEND command to support defining the
2001 local IP and port for key exchange listener. They are
2002 optional. Affected file irssi/src/silc/core/silc-servers.c.
2004 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * Defined to WHOIS command reply the sending of fingerprint
2007 of the client's public key (if the proof of posession of the
2008 corresponding private key is verified by the server).
2009 Updated to the protocol specification.
2011 * Added support of receiving the client's public key's
2012 fingerprint in command reply in client library. Affected
2013 file is lib/silcclient/command_reply.c, and
2014 lib/silcclient/idlist.[ch].
2016 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2018 * Do not send over 128 chars long nickname to the server
2019 in NICK command. Affected file lib/silcclient/command.c.
2021 * Do not send over 256 chars long channel names to the server
2022 in JOIN command. Affected file lib/silcclient/command.c.
2024 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Assure that silc_server_close_connection cannot be called
2027 twice for same socket context. Affected file is
2030 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * Send error message to application if opening file for
2033 writing during file transfer fails. Affected file is
2034 lib/silcclient/client_ftp.c.
2036 Remove all file transfer sessions for a client that we're
2037 removing from ID cache.
2039 Affected file is lib/silcclient/client_ftp.c.
2041 * Fixed silc_net_addr2bin to return correct address. Affected
2042 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2044 * Fixed file transfer session removing on signoff notify.
2045 Affected file irssi/src/silc/core/silc-servers.c.
2047 * Added the SilcClientFileError to be returned in the monitor
2048 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2049 Affected file lib/silcclient/silcapi.h.
2051 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Fixed a crash in silc_client_ftp_free_sessions and
2054 silc_client_ftp_session_free_client. Affected file
2055 lib/silcclient/client_ftp.c.
2057 * Added `disabled' field in the SilcChannelEntry in the server
2058 to indicate if the server entry is disabled. Affected file
2059 silcd/idlist.h, silcd/command[_reply].c.
2061 * SILC server adds now /var/run/silcd.pid everytime it is
2062 started. Affected file silcd/silcd.c.
2064 * Added silc_server_packet_send_clients to send a packet to
2065 the provided table of client entries. Affected file
2066 silcd/packet_send.[ch].
2068 * Fixed a crash in client resolving in client_prvmsg.c in
2069 client library. Affected file lib/silcclient/client_prvmsg.c.
2071 * Do not actually remove the client directly from ID cache
2072 during SERVER_SIGNOFF, but invalidate it. This way we
2073 preserve the WHOWAS info for the client. Affected file
2074 silcd/server_util.c.
2076 * Fixed SERVER_SIGNOFF notify handling in the server. The
2077 server is now able to process incoming SERVER_SIGNOFF notify
2078 for a server that it doesn't even know about. It will remove
2079 the clients provided in the notify. Affected file
2080 silcd/packet_receive.c.
2082 * Check for partial packet in data queue after every packet that
2083 was found from the queue. Return and wait for more data if
2084 there is partial data in queue. Affected file is
2085 lib/silccore/silcpacket.c.
2087 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Added SilcClietFileError enum to indicate error in
2090 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2091 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2092 Affected files lib/silcclient/silcapi.h and
2093 lib/silcclient/client_ftp.c.
2095 * Check that newsize in silc_buffer_realloc is larger than
2096 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2098 * Added better monitor of file transfers. It now monitors
2099 key agreement protocol during the file transfer too. Added
2100 error reporting too. Affected files
2101 irssi/src/silc/core/silc-servers.c,
2102 irssi/src/fe-common/silc/module-formats.[ch].
2104 * Wrote a help file for FILE command.
2106 * Added silc_rng_global_get_byte_fast to get not-so-secure
2107 random data as fast as possible. Random data is read from
2108 /dev/urandom if available and from the SILC RNG if not
2109 available. It is used in padding generation. Affected file
2110 lib/silccrypt/silcrng.[ch].
2112 * All packets in client library are now processed synchronously.
2113 Optimized packet processing a lot. Affected file
2114 lib/silcclient/client.c.
2116 * All server connection packets are processing synchronously
2117 now in server, to optimize packet processing. Affected file
2120 * Include files are installed now only in Toolkit distribution
2121 if make install is given. Affected files: all Makefile.am's.
2123 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Assure that silc_client_notify_by_server_resolve does not
2126 resolve the client information multiple times. If it cannot
2127 be found by the first it cannot be found at all. Affected
2128 file lib/silcclient/client_notify.c.
2130 * Fixed WHOWAS command reply calling. Affected file
2131 lib/silcclient/command_reply.c.
2133 * Removed all references to silc_idlist_get_client from the
2134 Irssi SILC client since that call is internal call used by
2135 the library. The Irssi SILC client will use now client
2136 retrieval functions found in silcapi.h.
2138 * Fixed a bug in resolving nickname info before sending
2139 private message. It used freed memory. Affected file
2140 irssi/src/silc/core/silc-servers.c.

2161 * Added silc_net_localip to return local host's IP address.
2162 Affected file lib/silcutil/silcnet.[ch].
2164 * If key exchange or rekey protocol is active for a connection
2165 parse all packets syncronously since there might be packets
2166 in packet queue that we are not able to process without first
2167 processing packets before them. Affected file silcd/server,
2168 lib/silcclient/client.c.
2170 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2171 whether library should continue processing the packet.
2172 Affected file lib/silccore/silcpacket.h.

2203 lib/silcutil/silcutil.[ch].
2205 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Resolve the client info when received private message or
2208 channel message for a client which nickname we don't know.
2209 Affected files lib/silcclient/client_prvmsg.c and
2210 lib/silcclient/client_channel.c.
2212 * Do not crash in /KEY if client is not connected. Affected
2213 file irssi/src/silc/core/silc-channels.c.

2218 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2219 is incomplete and is being resolved, it won't be resolved
2222 Make sure also that USERS command reply does not resolve
2223 twice information. Affected file is
2224 lib/silcclient/command_reply.c.
2226 Make sure that silc_client_get_clients_by_list does not
2227 resolve twice same information.
2229 * Check for valid client->id in the silc_server_free_client_data.
2230 Affected file silcd/server.c.
2232 * Fixed /GETKEY nick@server not to crash if the server entry
2233 is not found. Affected file lib/silcclient/command.c.
2235 * Fixed the silc_server_check_cmode_rights to check the
2236 requested modes correctly. Affected file silcd/command.c.
2238 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Better checks for non-printable chars in nick added.
2241 Affected file silcd/command.c.
2243 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2245 * Call the silc_server_udpate_servers_by_server in the
2246 primary router that comes back online in the backup resuming
2247 protocol. Otherwise it routes packets wrong. Affected file
2248 silcd/server_util.[ch], silcd/server_backup.c.
2250 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2252 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2253 lib/silcutil/silcbuffmt.[ch].
2255 * Redefined the SILC packet header to include the padding
2256 length. Affected file lib/silccore/silcpacket.[ch].
2258 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2259 length for maximum padding up to 128 bytes). Affected
2260 file lib/silccore/silcpacket.h.
2262 * Removed all backwards support for old 0.5.x MAC thingies.
2263 The SILC packet header change makes it impossible to be
2264 backwards compatible.
2266 * Send the ENDING packet with timeout in the backup resuming
2267 protocol. This is to assure that all routers has connected
2268 to the primary router. Affected file silcd/server_backup.c.
2270 * Changed the RNG to take the first IV from random data. It
2271 used to take it from zero actually. Changed the RNG also
2272 to use /dev/urandom during session. /dev/random is used
2273 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2275 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Changed the SILC packet header to have the first two bytes
2278 (the packet length) encrypted. Affected files aroung the
2279 code tree, lib/silccore/silcpacket.[ch]. Removed the
2280 SilcPacketCheckDecrypt callback. It is not needed anymore
2281 since the silc_packet_receive_process will determine now
2282 whether the packet is normal or special.
2284 * Implemented the unidirectional MAC keys. Affected files
2285 lib/silcske/silcske.c, silcd/protocol.c and
2286 lib/silcclient/protocol.c.
2288 * Implemented the packet sequence number to the MAC computation.
2289 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2290 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2291 lib/silcclient/protocol.c.
2293 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Allow backup router to announce servers. All servers
2296 announced by backup router are added to the global list
2297 automatically. Update hte server's socket to our primary
2298 router also when backup router announces a server.
2299 Affected file silcd/packet_receive.c.
2301 * Do not update the client->router in the function
2302 silc_server_udpate_clients_by_server if the client is on
2303 global list. We might fail to find any specific server
2304 for locally connected clients and local cell clients. They
2305 should still use the `from' and not `to' as client->router.
2306 This fixes backup router resuming protocol. Affected file
2307 silcd/server_util.c.
2309 * Decrease channel statistics count only if the channel
2310 deletion worked. Affected files are silcd/server.c and
2311 silcd/server_util.c.
2313 * Added silc_server_update_servers_by_server to update origin
2314 of all server entries. Used during backup router protocol.
2315 Affected files silcd/server_util.[ch], silcd/server.c. and
2316 silcd/backup_router.c.
2318 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2319 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2320 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2321 lib/silccrypt/silchmac.c.
2323 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Assure that router cannot reroute the same channel message
2326 to the sender. Affected file silcd/packet_receive.c.
2328 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Made better checks that the channel message is not sent
2331 to the router it came from. Affected file is
2332 silcd/packet_send.c. Fixed memory leak too.
2334 * Announce informations for incoming router connection, but
2335 only after checking if it is replaced by backup router.
2336 Affected file silcd/packet_receive.c.
2338 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Fixed the backup resuming protocol to work in multiple
2341 router environment. Affected file silcd/server_backup.c.
2343 * Route packet only to one router in the function
2344 silc_server_packet_send_to_channel. Affected file is
2345 silcd/packet_send.c.
2347 * Fixed silc_server_send_notify_dest to set the broadcast
2348 flag. Fixed the silc_server_send_notify_topic to actually
2349 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2350 Affected file silcd/packet_send.c.
2352 * Changed the SFTP Filesystem interface. Changed the
2353 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2354 the filesystem operation function. The SilcSFTPFilesystem
2355 is now a context that is allocated by all filesystem allocation
2356 functions and it already includes the operations structure
2357 and filesystem specific context. It is given as argument
2358 now to the silc_sftp_server_start. This made the interface
2359 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2360 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2362 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Changed the backup router adding and getting interfaces
2365 in the server. The router that will be replaced by the
2366 specified backup router is now sent as argument. Affected
2367 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2370 * Added silc_net_addr2bin_ne to return the binary form of
2371 the IP address in network byte order. Affected files
2372 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2374 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Check for existing server ID in silc_server_new_server
2377 and in silc_server_connect_to_router_final and remove the
2378 old entry if it exists. Affected file silcd/packet_receive.c,
2381 * Send the channel message always to only one router, either
2382 in upstream or downstream. Affected file is
2383 silcd/packet_send.c.
2385 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Wrote the definition of the backup resuming protocol to the
2388 protocol specification.
2390 * Removed one redundant channel key generation from normal
2391 server during joining procedure. Removed one redundant
2392 channel key sending from server to router during joining
2393 procedure. Affected file silcd/command.c.
2395 * Made minor bugfixes to the backup router resuming protocol.
2396 Affected file silcd/server_backup.c, server.c.
2398 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Added --disable-asm configuration option. Affected files
2401 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2404 * Implemented the backup resuming protocol that is used to
2405 resume the primary router position in the cell after the
2406 primary router comes back online. Affected files
2407 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2408 and silcd/server_util.[ch].
2410 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Sleep two (2) seconds after sending QUIT command to server.
2413 Affected file lib/silcclient/command.c.
2415 * Assure that if outgoing data buffer is pending do not force
2416 send any data. Affected file silcd/packet_send.c.
2418 * Assure that if outgoing data buffer is pending do not force
2419 send any data. Affected file lib/silcclient/client.c.
2421 * Implemented the backup router support when the primary router
2422 goes down. The servers and routers can now use the backup
2423 router as new primary router without loosing connectivity.
2425 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2428 in the server to indicate disabled entry. All data read
2429 from the connection will be ignored and no data is sent
2430 for entry that is disabled. Affected files are
2431 silcd/idlist.h, silcd/server.c.
2433 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Created SFTP client and server test programs in the
2436 lib/silcsftp/tests directory.
2438 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Implemented memory filesystem (virtual filesystem) for
2441 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2444 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Implemented the SFTP (SSH File Transfer Protocol) to the
2447 lib/silcsftp. It includes SFTP client and SFTP server
2450 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Moved lib/silccore/silcprotocol.[ch] to the
2453 lib/silcutil library.
2455 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2456 take variable argument list pointer as argument. Affected
2457 file lib/silcutil/silcbuffmt.[ch].
2459 * Added silc_buffer_set function that is used to set data
2460 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2461 Affected file lib/silcutil/silcbuffer.h.
2463 * Changed various routines in the core library to use the new
2464 silc_buffer_set instead of allocating new buffer only for
2467 * Added 64-bit value formatting and unformatting support to the
2468 silc_buffer_[un]format routines. Affected file is
2469 lib/silcutil/silcbuffmt.[ch].
2471 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2472 to includes/bitmove.h.
2474 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Fixed channel user mode saving in client library. Affected
2477 file lib/silcclient/command[_reply].c.
2479 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Defined the file transfer to the SILC Protocol. Added
2482 new packet type SILC_PACKET_FTP and defined File Transfer
2483 Payload. The mandatory file transfer protocol is SFTP
2484 (SSH File Transfer Protocol). Affected file in addition
2485 of the internet draft is lib/silccore/silcpacket.h.
2487 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2488 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2489 is used as part of backup router protocol when the primary
2490 router of the cell is back online and wishes to resume
2491 the position as primary router.
2493 * Redefined the MAC generation keys in the protocol. The
2494 same key is not used anymore in both direction. Both
2495 direction will now use different keys for sending and
2496 receiving. This fixes a potential security flaw. This
2497 change causes incompatibilities in the protocol.
2499 * Redefined also the MAC computation from the packet.
2500 An packet sequence number is now added to the MAC
2501 computation. This prevents possible replay attacks against
2502 the protocol. This change too causes incompatibilities
2505 Added `sequence' field to the SilcPacketContext to hold
2506 the current sequence number for the packet.
2508 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Added `created' field to the SilcIDListData in the file
2511 silcd/idlist.h to indicate the time when the entry was
2514 * Added `created' field to the SilcChannelEntry too. Affected
2515 file silcd/idlist.h.
2517 * Added `creation_time' aguments to all the announcement functions
2518 in the server. If it is provided then only the entries that
2519 was created after the provided time frame are actually
2520 announced. Affected file silcd/server.[ch].
2522 * The protocol says that the Channel ID's IP address must be
2523 based on the router's IP address. Added check for this in
2524 the silc_server_new_channel when processing incoming New Channel
2525 Payload. Affected file silcd/packet_receive.c.
2527 * Print out the correct version with --version in SILC client.
2528 Affected file irssi/src/silc/core/silc-core.c.
2530 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Fixed WHOWAS command to check for completnes of the client
2533 entry always, not just when the command is coming from client.
2534 Affected file silcd/command.c.
2536 * Added new function silc_server_packet_queue_purge to purge the
2537 outgoing data queue to the network. After the function returns
2538 it is guaranteed that the outgoing packet queue is empty.
2539 Affected file silcd/packet_send.[ch].
2541 * Purge the outgoing packet queue in the rekey protocol's final
2542 callback to assure that all rekey packets go to the network
2543 before quitting the protocol. Affected file silcd/server.c.
2545 * Added silc_client_packet_queue_parse as similar function as
2546 in server to the client library. The affected file is
2547 lib/silcclient/client.c.
2549 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Splitted silcd/server.c and created silcd/server_util.[ch]
2552 for utility functions.
2554 * Added new socket flag SILC_SF_DISABLED to indicate that the
2555 connection is open but nothing can be sent to or received from
2556 the connection. Affected file lib/silcutil/silsockconn.[ch].
2557 The checking for disabled socket is checked in the low level
2558 silc_socket_write and silc_socket_read functions.
2560 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Allow only nicknames and channel names that fits into the
2563 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2565 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * When processing JOIN command reply in server check that if
2568 the channel exists in our global list we'll move it the local
2569 list. Affected file silcd/command_reply.c.
2571 * Fixed the check whether client is joined on the channel already
2572 in JOIN command. Affected file lib/silcclient/command.c.
2574 * Fixed the JOIN command reply to check whether the channel
2575 already exists. Affected file lib/silcclient/command_reply.c.
2577 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Added silc_ske_status_string to map the SKE error numbers
2580 to readable strings. The affected files are
2581 lib/silcske/silcske[_status].[ch].
2583 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Do not show the private channels on the WHOIS channel list
2586 as it is not allowed by the protocol. The affected file is
2589 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * Assure that the packet length digged from the actual packet
2592 is something sensible in the silc_packet_decrypt_rest_special
2593 in lib/silccrypt/silcpacket.c.
2595 * Free and NULL the allocated pointer in silc_hmac_alloc if
2596 the HMAC allocation fails. The affected file is
2597 lib/silccrypt/silchmac.c.
2599 * Print the selected security properties to the log files in
2600 the server. Affected file silcd/protocol.c.
2602 * Add SKE's reference counter even if calling the completion
2603 callback manually. Otherwise it goes negative, although it
2604 does not cause any problems. The affected file is
2605 lib/silcske/silcske.c.
2607 * Remove the client entry with short timeout after giving the
2608 KILL command. Affected file lib/silcclient/command.c.
2610 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2611 case all found clients are already disconnected (WHOWAS would
2612 found them) in the server. Affected file silcd/command.c.
2614 * Update the last_receive (time of last data received) to be
2615 updated only when received private or channel message so that
2616 the idle time showed in WHOIS makes more sense.
2618 * Added boolean field `valid' in to the SilcClientEntry in the
2619 client library to indicate whether the entry is valid or not.
2620 This fixes the nickname change bug on channel when changing
2621 the nickname to be same than the old (like nick to Nick) the
2622 nickname formatter doesn't set the new nick anymore to Nick@host.
2623 Affected file lib/silcclient/idlist.[ch].
2625 * Now actually fixed the nickname changing on disconnection.
2626 Added new function silc_change_nick to the Irssi SILC Client.
2627 Affected file irssi/src/silc/core/client_ops.c,
2628 irssi/src/silc/core/silc-nicklist.[ch].
2630 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * Check that the public key exists in the GETKEY command before
2633 trying to encode it. Affected file silcd/command.c.
2635 * Print some notifications on received public keys with GETKEY
2636 command in the Irssi SILC Client. Affected files are
2637 irssi/src/fe-common/silc/module-formats.[ch],
2638 irssi/src/silc/core/client_ops.c.
2640 * Use IDENTIFY command to resolve the server information in the
2641 GETKEY command instead of INFO command. Affected file
2642 lib/silcclient/command.c.
2644 * All command reply functions in the client library now calls
2645 the pending command reply callbacks even if an error has
2646 occurred. The server has done this a long time and now it was
2647 time to move the client library to this as well. Now all
2648 errors can be delivered back to the pending command reply
2649 callbacks if necessary. Affected files are
2650 lib/silcclient/command[_reply].[ch].
2652 * Change the nickname on disconnection back to the username
2653 because in reconnect the server will enforce it to it anyway.
2654 Affected file irssi/src/silc/core/silc-servers.c.
2656 * Fixed a config file parsing bug in the Irssi SILC client.
2657 Affected file irssi/src/silc/core/clientconfig.c.
2659 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * When printing the channel mode on JOIN, verify that the
2662 channel key and channel's HMAC are valid. Affected file
2663 irssi/src/silc/core/client_ops.c.
2665 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2668 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2669 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2671 * Removed channel key rekey task deleting from the function
2672 silc_server_save_channel_key. Affected file silcd/server.c.
2673 Added explicit timeout task context instead that is used to
2674 delete the task if we are registering a new task before the
2675 new task has elapsed.
2677 * When channel key rekey occurs the client library now saves
2678 the old channel key for a short period of time (10 seconds) and
2679 is able to use it in case some is still sending channel
2680 messages encrypted with the old key after the rekey. Affected
2681 file lib/silcclient/[idlist.h|client_channel.c].
2683 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Added check to the silc_server_new_id_real to not accept
2686 new ID if it is the sender's own ID. Affected file is
2687 silcd/packet_receive.c.
2689 * Assure that we do not announce ourself or the one we've
2690 sending our announcements when we're router and are announcing
2691 servers to our primary router. Affected file silcd/server.c.
2693 * Fixed silc_server_command_identify_check_client to assemble
2694 correct WHOIS packet. It send corrupted WHOIS packet and
2695 caused problem with router to router connections. Affected
2696 file silcd/command.c.
2698 Fixed also silc_server_command_whois_check the same way
2699 as for the IDENTIFY command.
2701 * Added new SilcIDListStatus to the server in the SilcIDListData
2702 structure. The status now includes the current status of
2703 the entry (like registered, resolved etc.). Affected file
2704 silcd/idlist.[ch]. Defined a bunch of different status types
2705 as well. This replaced the old boolean registered field as well.
2707 Added resolve_cmd_ident field to the SilcClientEntry structure
2708 too so that if the entry is for example being resolved so
2709 another command may attach to the same pending command reply
2710 without requiring to resolve the same entry again. This concept
2711 should optimize the WHOIS and the IDENTIFY resolving under
2712 heavy load by taking away unnecessary resolving for entries
2713 that are being resolved already.
2715 Added support for adding multiple pending commands for one
2716 command idenfier. Affected file silcd/command[_reply].[ch].
2718 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2719 before deleting the data. Otherwise the hash table will have
2720 freed data in comparison functions. Affected file is
2721 silcd/command_reply.c.
2723 * Fixed silc_idlist_replace_client_id to add the new entry to
2724 the cache with NULL nickname. Otherwise there will be invalid
2725 memory as the nickname after the nickname is freed. Affected
2726 file silcd/packet_receive.c.
2728 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2729 saved into wrong slots because the previous number of entries
2730 was not taken into account. Affected file silcd/idlist.c.
2731 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2733 * If we are router and we receive JOIN notify to a channel that
2734 does not have any users then notified client is marked as the
2735 channel founder, as it is it. The affected file is
2736 silcd/packet_receive.c
2738 * Added to the extended hash table API's table_del_*ext functions
2739 the destructor as argument too, so that the caller can decide
2740 which destructor to use or whether to use destructor at all.
2741 Affected file lib/silcutil/silchashtable.[ch].
2743 * Fixed ID Cache purging. It actually deleted the entries from
2744 the hash table after the data was freed. The hash table ended
2745 up comparing freed memory. The affected file is
2746 lib/silccore/silcidcache.c.
2748 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2750 * Fixed Irssi SILC client's KILL command's HELP syntax.
2752 * The USERS command now resolves the detailed user information
2753 if the userinfo field is missing. Affected file is
2754 lib/silcclient/command_reply.c.
2756 * Do not print error in silc_file_read if the read file does
2757 not exist. Just silently return NULL. Affected file is
2758 lib/silcutil/silcutil.c.
2760 * Fixed the silc_log_output to not wine about NULL filename
2761 and to not create some bogus " " filename. Affected file is
2762 lib/silcutil/silclog.c.
2764 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Fixed various printing bugs on the user interface in the
2767 Irssi SILC Client. Minor changes that were forgotten from
2770 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Fixed the configure.in.pre and the compilation and distribution
2773 environment to support the new autoconf 2.52. That version is
2774 now required to compile the CVS trunk.
2776 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2779 to generally parse user@fqdn format strings. Affected file
2780 lib/silcutil/silcutil.c.
2782 * Added nickname_format and nickname_force_format fields to the
2783 SilcClientParams structure. The first one defines the format
2784 for the nicknames that the library will enforce if the receives
2785 multiple same nicknames. The second one is boolean value and
2786 can be used to force the library to always enforce the format
2787 to the nicknames regardles whether there are multiple nicknames
2788 or not. This configurable formatting was employed to flexibly
2789 support accessing multiple nicknames from the user interface.
2790 The userinterface can now set the nicknames to what ever format
2791 they prefer. Affected file lib/silcclient/silcapi.h.
2793 Added function silc_client_nickname_format to the file
2794 lib/silcclient/idlist.c. It performs the nickname formatting.
2796 Added new field `hostname´ to the SilcClientEntry context.
2797 It holds the hostname of the client. Affected file is
2798 lib/silcclient/idlist.h.
2800 * Irssi SILC Client sets the nicknames in nick@hostn format.
2801 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2802 irssi/src/silc/core/silc-core.c.
2804 The WHOIS printing now also shows both the real nickname and
2805 the formatted nickname so that user knows how to access the
2806 user if there are multiple same nicknames cached. Affected
2807 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2808 printing formatting too to take the hostname now as a separate
2809 argument. The Affected file is
2810 irssi/src/fe-common/silc/modules-formats.[ch].
2812 * Changed the silc_client_get_clients_local to accept the formatted
2813 nickname as argument. It accepts the real nickname too but the
2814 formatted nickname can be used to find the true entry from
2815 multiple entries. Affected file lib/silcclient/silcapi.h and
2816 lib/silcclient/idlist.c.
2818 * Added nickname_format_parse field to the SilcClientParams.
2819 It is a callback function provided by the application to parse
2820 the nickname out of the formatted nickname string. The library
2821 calls it to get the nickname from the formatted string. Since
2822 the application generally knows better the format of the nickname
2823 string it parses it instead of the library, even though library
2824 encodes the formatted string. If the callback function is not
2825 provided then the library will use the string as is. The
2826 affected file is lib/silcclient/silcapi.h.
2828 * All the nickname strings passed to the client library in
2829 commands are now expected to be formatted nickname strings.
2830 If the command does not support the formatted nickname string
2831 it will assume that the sent string is the actual nickname.
2832 Affected file lib/silcclient/command.c.
2834 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Added public key authentication support to OPER and SILCOPER
2837 commands in the client library. Affected file is
2838 lib/silcclient/command.c.
2840 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Changed the get_auth_methdod client operation to be asynchronous.
2843 It can be async if the application resolves the authentication
2844 method from the server during the negotiation. Added new
2845 SilcGetAuthMeth completion callback that the application will
2846 call after resolving the authentication method.
2848 Added function silc_client_request_authentication_method that
2849 the application can use to resolve the authentication method
2850 from the server. Added also SilcConnectionAuthRequest callback
2851 that the library will call after the server has replied. The
2852 application can call this function if it does not know the
2853 current authentication method.
2855 Affected files are lib/silcclient/client.c and
2856 lib/silcclient/silcapi.h.
2858 * The Irssi SILC client now automatically resolves the authentication
2859 method incase any configuration information is not present (and
2860 currently there never is). The affected file is
2861 irssi/src/silc/core/client_ops.c.
2863 * Fixed public key authentication from the client library.
2864 Affected file lib/silcclient/protocol.c. Changed also the
2865 protocol specification about the public key authentication in
2866 the connection authentication protocol. The actual data to be
2867 signed is now computed with a hash function before signing.
2869 * Fixed the public key authentication from the server as well.
2870 Affected file silcd/protocol.c.
2872 * Removed the mlock()'s from the memory allocation routines.
2873 Affected file lib/silcutil/silcmemory.c. The ./configure does
2874 not check anymore for the mlock(). Affected file is
2877 * Fixed USERS command in server to allow the execution of the
2878 command for private and secret channels if the client sending
2879 the command is on the channel. Affected file silcd/command.c.
2881 * Fixed silc_client_get_clients_local to return the clients
2882 count correctly. It could return wrong value. Affected file
2883 lib/silcclient/idlist.c.
2885 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2888 types. The assembler optimizations seemed not to like 64-bit
2889 data types. The assmebler optimizations thus are now enabled
2890 also for BSD systems as opposed to only enable them for Linux.
2892 * Do not check for threads at all on BSD systems. Affected
2893 file configure.in.pre.
2895 * Removed -n and -h options from the Irssi SILC Client since
2896 they are not used in silc.
2898 * Fixed the prime generation to assure that the first digit
2899 of the generated random number is not zero since our conversion
2900 routines does not like number strings that starts with zero
2901 digit. If zero digit is seen the random number is regenerated.
2902 This caused some corrupted RSA keys when the zero first digit
2903 was met. Affected file lib/silcmath/silcprimegen.c.
2905 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Fixed WIN32 configuration in the ./configure script.
2908 Fixed to include xti.h on environments that has it.
2909 Patches by Carsten Ilchmann and andrew.
2911 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Changed the silc_id_create_client_id to be collision
2914 resistant. It is now assured that there cannot be created
2915 two same client ID's. I suspect that some weird bugs in
2916 the server were actually caused by duplicate Client IDs.
2917 Affected file silcd/serverid.[ch]. A router receiving
2918 new ID now also assures and informs the sending server
2919 if the ID caused collision.
2921 * Changed the silc_id_create_channel_id to also assure that
2922 there are no collisions.
2924 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Statement about ignoring the Mutual Authentication flag when
2927 performing rekey with PFS was a bit misleading. It is ignored
2928 if it was set in the initial negotiation, it cannot be even
2929 set in the rekey. Fixed in the ke-auth draft. Started the
2930 new versions of the protocol drafts in the doc/.
2932 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Fixed a bug in silc_client_command_identify_save when saving
2935 new channel information. The channel name was no duplicated
2936 and caused crash on exit. Affected file is
2937 lib/silcclient/command_reply.c.
2939 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Fixed the getkey command handling in the server. Send just
2942 empty OK reply to the sender if the key could not be fetched
2943 (but everything else was ok, like the key just was not available).
2944 Changed the public key parameter to optional in the protocol
2945 specs so that empty OK reply can be sent. Affected file
2948 Added a message to Irssi SILC client to tell to user if the
2949 server did not return a public key.
2951 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Fixed a channel key regeneration bug. It registered new
2954 timeout tasks exponentially until all system resources were
2955 used. Affected file silcd/server.c.
2957 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Added the SILC Document generator to the scripts/silcdoc.
2960 It can be used to generate the Toolkit Reference Manual out
2961 of the source tree. Internally it will also use the RoboDoc
2962 generator now imported in util/robodoc.
2964 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Added couple of return's in rekey protocol if error orccurred
2967 during the protocol. The execution must be terminated.
2968 Affected file silcd/protocol.c. Also, terminate the protocol
2969 always with timeout.
2971 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * The client's Client ID was created initally from the wrong
2974 nickname (it could have been in format nick@host) in the
2975 silc_server_new_client. Affected file silcd/packet_receive.c
2977 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * Added some SILC_LOG_ERROR's to various error conditions
2980 if client could not be added to ID cache. Affected files
2981 silcd/packet_receive.c and silcd/server.c.
2983 * When client's sock->user_data is freed, NULL also the
2984 client->router and client->connection pointers. Added check
2985 for these pointers being NULL to various places around the
2986 code. Affected file silcd/server.c.
2988 * Added client->data.registered == TRUE checks to various
2989 places around the code to assure that unregistered client's
2990 are not handled when it is not allowed. Affected file
2993 * Added `bool registered' fields to all
2994 silc_idlist_[server|client]_get_* routines to indicate whether
2995 the fetched client needs to be registered or not. Affected
2996 file silcd/idlist.[ch].
2998 * Add your own entry as registered to the ID cache in the
2999 server. Affected file server.c.
3001 * Fixed a bug in silc_server_new_server. The SilcServer was
3002 set as the new server's context instead of SilcServerEntry.
3003 This naturally caused some weird bugs.
3005 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Do not delete the channel rekey task when adding it
3008 for in silc_server_create_channel_key.
3010 * Changed the silc_server_create_channel_key to return
3011 TRUE or FALSE to indicate the success of the channel key
3014 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Fixed MSVC++ project files and added missing files to
3017 Makefiles under win32/.
3019 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Do not add TCP_NODELAY flag if the operating system
3022 does not have it defined. Affected files are
3023 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3025 * Fixed buffer overflow from Irssi SILC Client. Affected
3026 file irssi/src/fe-common/core/themes.c.
3028 * Fixed double free in client library in the file
3029 lib/silcclient/client.c when disconnecting from server.
3031 * Applied double free patch from cras to Irssi SILC client.
3032 Affected files irssi/src/core/[modules/expandos].c
3034 * Fixed the disconnection handling to Irssi SILC Client.
3035 The application must call silc_client_close_connection
3036 in ops->connect client operation in case of failure of
3037 the connection. Affected file is
3038 irssi/src/silc/core/client_ops.c.
3040 * Do not set sock->protocol to NULL in the function
3041 silc_client_close_connection after executing the protocol's
3042 final callback since the sock might not be valid anymore.
3043 Affected file lib/silcclient/client.c.
3045 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Do not enable SILC_THREADS if the linking with libpthread
3048 did not happen. Affected file configure.in.pre.
3050 * Added notion to protocol specification that server must
3051 verify the sent authentication payload with CMODE when
3052 setting the channel founder key. Implemented it to the
3053 server. Affected file silcd/command.c.
3055 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Added _EXTRA_DIST SILC distribution variable to the
3058 distributions file. It is used to conditionally add extra
3059 files or directories to the specific distribution. Affected
3060 files ./prepare, Makefile.am.pre and distributions.
3062 Removed the `_' from the start of the distribution names.
3065 * Added README.WIN32 for instructions to compile the Toolkit
3068 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Fixed a double free in disconnection in the server. Affected
3071 file is silcd/server.c.
3073 * Fixed the lib/silcske/groups.c to work now also with GMP
3074 MP library. The string conversion did not work when using
3075 specific base and the base is indicated in the string as well.
3077 * Created win32/ directory which now includes MSVC++ specific
3078 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3079 It will appear only in the toolkit distribution
3081 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Changed the key material distribution function in case when
3084 the hash output is too short. The data is now concatenated
3085 a bit differently than it used to. Made the change to the
3086 SKE protocol specification.
3088 * Added better GMP detection to configure.in.pre. A patch
3091 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Fixed a minor bug in SKE that might cause some problem on
3094 some platforms. Affected file lib/silcske/silcske.c.
3096 * Added the cookie checking for initiator in the SKE. It checks
3097 that the responder returns the sent cookie unmodified. The
3098 affected file is lib/silcske/silcske.c. Added new SKE
3099 error type INVALID_COOKIE that can be sent during the
3100 negotiation. Fixed some memory leaks as well.
3102 * Added the "invalid cookie" error message to Irssi SILC client's
3105 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Added `task_max' field to the SilcClientParams to indicate
3108 the maximum tasks the scheduler can handle. If set to zero,
3109 default values are used. Affected file lib/silcclient/silcapi.h.
3111 * Fixed memory leaks in silc_client_close_connection. Affected
3112 file lib/silcclient/client.c.
3114 * Added silc_client_del_client_entry to client library to free
3115 all memory of given client entry. Affected file is
3116 lib/silcclient/idlist.[ch].
3118 * Added new functions silc_client_del_channel and
3119 silc_client_del_server to delete channel and server entries.
3120 Affected file lib/silcclient/[silcapi.h/idlist.c].
3122 * Removed silc_client_del_client_by_id from silcapi.h.
3124 * Fixed the INFO command to return the server's own info
3125 correctly when querying by Server ID. Affected file is
3128 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3130 * Removed the non-blocking settings in WIN32 code in the
3131 silc_sock_[read/write] and added SleepEx instead. Affected
3132 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3133 of input data is now checked with FIONREAD and ioctlsocket.
3135 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3137 * Call silc_schedule_task_del_by_context in the
3138 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3139 Affected file lib/silccore/silcprotocol.c.
3141 * Call silc_protocol_cancel for active protocols in the
3142 silc_server_close_connection if the funtion
3143 silc_server_free_sock_user_data has not been called.
3144 Affected file silcd/server.c.
3146 * Generic tasks cannot be deleted using the del_by_fd
3147 task deleting function since generic tasks does not match
3148 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3150 * Added a notion to SILCOPER help file that the SILCOPER works
3151 only on router server, not on normal server.
3153 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Added for WIN32 support for the new scheduler as well.
3156 Affected file lib/silcutil/win32/silcwin32schedule.c.
3158 * Fixed the SHA1 implementation to work on various platforms.
3160 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3162 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3163 API. It is part of the scheduler now. Everything else is
3164 as previously but some functions has changed their names.
3165 Checkout the lib/silcutil/silcschedule.h for the interface.
3166 Updated all applications to use the new interface. Affected
3167 files are lib/silcutil/silcschedule.[ch].
3169 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * Found a bug in the SKE implementation. The HASH value,
3172 specified by the protocol, was not computed correctly. The
3173 public key of the responder was not added to the computation
3174 even though it is mandatory. Affected file lib/silcske/silcske.c.
3175 This unfortunately causes incompatibilities with older
3176 clients and servers.
3178 * Added WIN32 specific network init and uninit functions:
3179 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3180 the Winsock2. Affected file lib/silcutil/silcnet.h and
3181 lib/silcutil/win32/silcwin32net.c.
3183 * Set the socket always to nonblocking mode on WIN32 after
3184 reading data or writing data. Affected file is
3185 lib/silcutil/win32/silcwin32sockconn.c.
3187 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Fixed various compilation problems under WIN32. Affected
3190 files lib/silcutil/win32/silcwin32thread.c and
3191 lib/silcutil/win32/silcwin32schedule.c.
3193 * Removed all _internal.h #includes from public header
3194 files. Internal headers must never be included from
3197 Removed also the lib/silcske/payload_internal.h file.
3199 * All include files that may be needed (public and some others
3200 included by the public headers) by application developers are
3201 now copied to the ./includes directory. It does not copy any
3202 internal headers. Affected file Makefile.defines.pre and all
3203 Makefile.am's under lib/ and subdirs.
3205 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Do not change the ~/.silc directory's permissions automatically.
3208 Affected file irssi/src/silc/core/clientutil.c.
3210 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Do not cancel the protocol in silc_server_close_connection
3213 it might cause recursion. Now cancelled in the function
3214 silc_server_free_sock_user_data. Affected file silcd/server.c.
3216 * Fixed the silc_server_remove_clients_by_server to regenerate
3217 the channel keys correctly finally. Added also new function
3218 silc_server_remove_clients_channels to actually do it.
3219 Affected file silcd/server.c.
3221 * Fixed the silc_server_new_channel to not crash by giving
3222 wrong router to the new channel. Affected file is
3223 silcd/packet_receive.c.
3225 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3227 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3228 which is given as argument to the silc_client_alloc now.
3229 It can be used to configure the client and set various parameters
3230 that affect the function of the client.
3232 * The USERS command in server did not check whether the channel
3233 is private or secret. Affected file silcd/command.c.
3235 * Added new argument to the USERS command in protocol specification.
3236 The USERS command now can take the channel name as argument
3237 as well. Added support for this in client and server and
3238 updated the protocol specs.
3240 * Completed the GETKEY command in client. It can be now used
3241 to fetch also servers public key not only some clients.
3242 Affected files lib/silcclient/command[_reply].c.
3244 * Added silc_client_get_server to return server entry by the
3245 server name. Affected files lib/silcclient/silcapi.h and
3248 * Redefined the IDENTIFY command in protocol specification to be
3249 more generic. It now can be used to query information about
3250 any entity in the SILC Network, including clients, servers and
3251 channels. The query may be based either the entity's name
3252 or the ID. Added support for this in both client and server.
3254 Affected files silcd/command.c and lib/silcclient/command.c
3255 and command_reply.c.
3257 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3258 the _from_client and _from_server functions. Affected file
3261 * Added silc_client_get_channel_by_id_resolve to the file
3262 lib/silcclient/silcapi.h to resolve channel information by
3263 its ID. Added also silc_client_get_channel_by_id that
3264 does not resolve it from the server.
3266 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3268 * Added SilcServerEntry context into the client library
3269 to represent one server. The INFO command now allocates
3270 these to save the resolved server info. For now on the
3271 client library will also keep information about servers,
3272 connected and resolved with INFO.
3274 The INFO command now allocates the SilcServerEntry context
3275 and saves the server info there. The COMMAND_REPLY in
3276 the INFO now returns the parameters to application in
3277 same order as defined in the protocol specification.
3279 The entries are cached in the client->server_cache.
3281 * The INFO command is now issued after received the Client ID
3282 from the server. Affected file lib/silcclient/client.c.
3284 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3285 to the application as the mode changer might be server.
3286 It is guaranteed that NULL is not returned anymore to the
3287 application. Affected file lib/silcclient/client_notify.c.
3289 The ID Type is now also passed to the application so that
3290 it can check whether the returned entry is SilcClientEntry
3293 Added new function silc_client_get_server_by_id to return
3294 the server entry by ID. Affected files are the
3295 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3297 * Do not create the channel in the Irssi SILC Client when issuing
3298 the JOIN command but when received the sucessful JOIN command
3299 reply. Otherwise the channel might get created even though we
3300 could not join it. The Affected file is
3301 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3303 * Fixed a channel joining bug in router. The router must also
3304 check the channel modes, invite and ban lists etc. when serving
3305 the JOIN command sent by normal server. Affected file is
3306 silcd/command.c. The router now resolves the client's
3307 information from the server who sent the JOIN command if it
3308 does not know it, and processes the JOIN command only after
3311 * Changed the SilcCommandCb to take new argument; void *context2.
3312 Affected file lib/silccore/silccommand.h
3314 The second argument in the command callbacks in the server now
3315 includes the SilcServerCommandReplyContext if the command was
3316 called as pending command callback from the command reply.
3317 Otherwise it is NULL. When called as pending the status of the
3318 command reply will be checked and if it was erronous the
3319 error will be sent to the original sender of the command.
3320 This way the client always receives the error messages even
3321 though the server was actually the one who received the error
3322 when it resent the command to router, for example. Affected
3323 files silcd/command[_reply].[ch].
3325 * Fixed sending WHOWAS command's error message to client if
3326 the requested client could not be found. It was missing.
3329 * Changed the CMODE and CUMODE commands reply arguments in the
3330 protocol specification. The Channel ID is now sent in both
3331 of the commands to identify the channel. Implemented this
3332 new feature to the client and server. Affected files
3333 lib/silcclient/command_reply.c and silcd/command.c.
3335 * Made better checks for invite and ban lists in the JOIN
3336 command in server. Affected file silcd/command.c.
3338 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * The server now performs the incoming host IP/DNS lookup
3341 using the silc_socket_host_lookup and thus does not block
3342 the server anymore. Affected file silcd/server.c.
3344 * Completed the multi-thread support for SILC Scheduler in
3345 the lib/silcutil/silcschedule.c.
3347 * Fixed the configure.in.pre to detect the pthread correctly
3350 * Fixed a deadlock in silc_task_queue_wakeup in the file
3351 lib/silcutil/silctask.c.
3353 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Added new function silc_schedule_wakeup that is used in
3356 multi-threaded environment to wakeup the main thread's
3357 schduler. It needs to be used when a thread adds a new task
3358 or removes a task from task queues. After waking up, the
3359 scheduler will detect the task queue changes. If threads
3360 support is not compiled in this function has no effect.
3361 Implemented the wakeup mechanism to both Unix and WIN32
3362 systems. Affected files are lib/silcutil/silcschedule.[ch],
3363 lib/silcutil/unix/silcunixschedule.c and the
3364 lib/silcutil/win32/silcwin32schedule.c.
3366 * Added new function silc_task_queue_wakeup to wakeup the
3367 scheduler by the specified task queue. Affected file
3368 lib/silcutil/silctask.[ch].
3370 * The silc_socket_host_lookup_start now wakes up the scheduler
3371 after adding the timeout task. Affected file is
3372 lib/silcutil/silcsockconn.c.
3374 * The silc_socket_host_lookup is synchronous now if the threads
3375 support is not compiled in. However, the callback is still
3376 called asyncronously through the scheduler, anyway. Affected
3377 file lib/silcutil/silcsockconn.c.
3379 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Added new function silc_socket_host_lookup to perform
3382 asynchronous IP and FQDN lookups for the socket connection.
3383 Affected files lib/silcutil/silcsockconn.[ch].
3385 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3388 that may or may not compile the mutex support in.
3390 Changed the silc_mutex_alloc interface. It allocates the
3391 mutex now to the sent pointer and returns TRUE or FALSE.
3393 Affected file lib/silcutil/silcmutex.h.
3395 * Wrote the SILC Task Queue interface to support multi-threads.
3396 Affected file lib/silcutil/silctask.[ch].
3398 * Wrote the SILC Scheduler to support multi-threads. Affected
3399 file lib/silcutil/silcschedule.c.
3401 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3403 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3404 in lib/silcutil/win32/.
3406 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Defined SILC Mutex API and SILC Thread API and implemented
3409 them for Unix. Affected files are
3410 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3411 lib/silcutil/unix/silcunixmutex.c and
3412 lib/silcutil/unix/silcunixthread.c.
3414 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Fixed the silc_server_remove_clients_by_server's channel
3417 key re-generation. The hash table handling was incorrect
3418 and would not work with many channels. Affected file is
3421 * Fixed some memory leaks around the server code.
3423 * Rewrote the silc_server_get_users_on_channel to support IPv6
3424 based Client ID's. Affected file silcd/server.c.
3426 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3427 specification. However, a separate document must be written
3428 to define the detailed signing procedure and the payload
3429 associated with the flag. Defined the flag to the
3430 lib/silccore/silcchannel.h as well.
3432 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Changed the dynamic tables to static size tables in the
3435 lib/silccrypt/silchmac.c.
3437 * Removed GCC dependencies from the code. A patch by cras.
3439 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Do not show the error "Error receiving packet bla bla"
3442 in server if it really was not an error (-2 means that reading
3443 is pending). Affected file silcd/server.c.
3445 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Fixed a possible crash in silc_server_remove_clients_by_server
3448 in silcd/server.c. Fixed there also some memory leaks.
3450 * Fixed the silc_idlist_replace_client_id. It could replace
3451 wrong key in the hash table. Affected file silcd/idlist.c.
3453 * Do not check whether there are global users on the channel
3454 if the channel->global_users is FALSE. Affected functions
3455 silc_server_remove_from_one_channel and
3456 silc_server_remove_from_channels in silcd/server.c. Also,
3457 do not check if the removed client is local as we can be
3458 sure that global client was not removed from the channel
3459 and checking for global users is not needed.
3461 * The silc_server_remove_clients_by_server now re-generates
3462 the channel keys correctly for those channels that had
3463 clients removed from them. Affected file silcd/server.c.
3465 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3467 * Found the reason of random crashes in the server. We weren't
3468 ignoring the SIGPIPE signal (which can be sent in write())
3469 and it crashed the server. Affected file silcd/silcd.c.
3471 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Assure that sock->user_data is not NULL in the function
3474 silc_server_packet_send in silcd/packet_send.c.
3476 * Disconnect the remote connection if it could not be added
3477 to any ID lists in the server. The affected file is
3480 * Check in silc_server_packet_send[_real/dest] that the
3481 socket is not disconnecting and ignore the data if it is.
3482 Affected file silcd/packet_send.c.
3484 * Define inline to __inline on native WIN32 compilation.
3485 Affected file includes/silcwin32.h.
3487 * Added some explicit type casts for inline code since MSVC
3488 require them. Affected files lib/silcutil/silcbuffer.h,
3489 lib/trq/silcdlist.h and lib/trq/silclist.h.
3491 * Print warning in log files from now on if the packet
3492 decryption fails. Affected file silcd/server.c.
3494 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3496 * Changed the `say' client operation's interface to accept
3497 new `type' argument to indicate the type of the message sent
3498 by the library. The application may filter the library's
3499 messages according the type. The affected file is the
3500 lib/silcclient/silcapi.h.
3502 * Added two new functions to lib/silcclient/silcapi.h:
3503 silc_client_del_client and silc_client_del_client_by_id.
3504 Affected file lib/silcclient/idlist.c.
3506 * Moved the clientincludes.h from includes/ to silc/ and
3507 serverincludes.h from includes/ to silcd/.
3509 * The modes for the CMODE and CUMODE are now passed as
3510 uint32 for application with COMMAND_REPLY. The affected
3511 file is lib/silcclient/command_reply.c.
3513 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * /WHOIS without arguments shows client's own information.
3516 Affected file lib/silcclient/command.c.
3518 * Changed PING to not accept any arguments. The specs
3519 says that client can ping only the connected server so
3520 requiring an argument is not needed. Affected file is
3521 lib/silcclient/command.c.
3523 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3525 * Fixed a fatal bug in private message sending and reception
3526 encryption and decryption when using private message keys.
3527 The implementation was incorrect and did not follow the
3528 specification. It causd that some of the message were
3529 lost since it did not use the sending and receiving keys
3530 as the protocol suggests. This has been fixed and will cause
3531 incompatibilities with older clients when sending private
3532 message encrypted with private message keys. Affected files
3533 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3534 and various other in Irssi SILC Client.
3536 Added `responder' boolean argument to the functions
3537 silc_client_add_private_message_key[_ske] to indicate when
3538 the key is added as responder or initiator of the key
3541 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * Removed the silc_ske_check_version function and created
3544 a SilcSKECheckVersion callback. Added also a function
3545 silc_ske_set_callbacks that is now used to set all SKE
3546 callbacks. The callback functions are not given to
3547 the SKE functions anymore, but this function is used to
3550 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3552 * Added `silc_version' argument to the silc_client_alloc
3553 to define the version of the application for the library.
3554 The library will use the version string to compare it
3555 against the remote host's (usually a server) version
3556 string. Affected file lib/silcclient/silcapi.h
3558 * Added the KE protocol context to Key Agreement context
3559 in client library so that we can abort the SKE if it
3560 is in process when we get timeout. Affected file is
3561 lib/silcclient/client_keyagr.c.
3563 * Do not resolve the client ID forever if it returns in the
3564 first time that such client does not exist. This was done
3565 for example with private message. Affected file is
3566 lib/silcclient/client_prvmsg.c.
3568 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * Do not add regex.h for WIN32. The affected file
3571 includes/silcincludes.h.
3573 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3574 not work yet 100%. It generates the DLL's automatically
3575 when compiling with --with-win32 under cygwin.
3577 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * lib/contrib/regex.c is not compiled on WIN32.
3581 * Added silc_net_get_socket_opt function to the
3582 lib/silcutil/silcnet.h.
3584 * Added includes/silcwin32.h for WIN32 specific includes
3587 * Do not use ptime structure or any of the posix process
3588 functions on WIN32 in lib/silccrypt/silrng.c.
3590 * Added silc_gettimeofday to provide generic function
3591 for struct timeval on all platforms. Added the function
3592 to lib/silcutil/silcutil.h.
3594 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3597 library as they clearly belong there. As a plus side we
3598 can make the actual socket connection routines platform
3601 Added also new generic function silc_socket_read and
3602 silc_socket_write (that used to be silc_packet_[read/write].
3603 The implementation of these are platform specific.
3605 * Added WIN32 specific routines of silc_socket_[read/write]
3606 to lib/silcutil/win32/silcwin32sockconn.c.
3608 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Added preliminary support for native WIN32 compilation under
3611 cygwin (using the -mno-cygwin option for GCC) to the
3612 ./configure.in.pre. The --with-win32 now prepares the
3613 compilation for native WIN32.
3615 * Rewrote the SILC Scheduler interface in the file
3616 lib/silcutil/silcschedule.h. The scheduler is now context
3617 based and does not have anymore any global static scheduler.
3618 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3619 and created lib/silcutil/win32 directory for WIN32 based
3622 * Added Unix specific network routines to the
3623 lib/silcutil/unix/silcunixnet.c and the old
3624 lib/silcutil/silcnet.c includes now only generic routines.
3626 Added WIN32 specific network routines to the
3627 lib/silcutil/win32/silcwin32net.c.
3629 * Added Unix specific utility functions from the
3630 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3632 * Added WIN32 SILC Scheduler to the file
3633 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3636 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3638 * Do not handle JOIN notify in the server if the target client
3639 is not registered (idata->registered == FALSE). The affected
3640 file is silcd/packet_receive.c.
3642 * Update the nickrec->founder in event_cumode in the Irssi SILC
3643 client. Affected file irssi/src/silc/core/silc-channels.c.
3645 * Fixed the CUMODE_CHANGE notify handling in the server when
3646 server and router are announcing their clients on channels.
3647 Now the mode changes are saved and notified correctly. The
3648 affected file is /silcd/packet_receive.c.
3650 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3651 They really did not replace the cache entry in the ID Cache.
3652 Now they do that. Affected file silcd/idlist.c.
3654 * Fixed the KICK notify handling in the Irssi SILC client to
3655 update the channel records so that the kicked client does not
3656 appear to be on the channel. The affected file is
3657 irssi/src/silc/core/silc-channels.c.
3659 * Always update the conn->current_channel when executing command
3660 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3662 * Fixed the KILL notify handling in Irssi SILC client to remove
3663 the killed client on all channels.
3665 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Fixed the silc_parse_command_line to remove extra spaces
3668 from the start and end of the arguments. Affected file is
3669 lib/silcutil/silcutil.c.
3671 * Cancel and free any active protocol in the function
3672 silc_server_close_connection. Affected file silcd/server.c.
3674 * Cancel and free any active protocol in the function
3675 silc_client_close_connction. Affected file is
3676 lib/silcclient/client.c.
3678 * Do not execute the KILL command for clients that are in
3679 history (ie. they are not in the network). Affected file is
3682 * Fixed KILL notify handling, client does not crash anymore.
3683 Affected file irssi/src/silc/core/silc-channels.c.
3685 * Reduced the default packet buffer size from 2048 to 1024 in
3686 lib/silccore/silcpacket.c.
3688 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3689 counter to the SKE context that is incresed when the SKE library
3690 performs async operation outside the library. If the outside
3691 process frees the SKE context and FREED status will be set
3692 and the library will detect after the sync operation that the
3693 libary is freed. The affected files are
3694 lib/silcske/silcske[_status].[ch].
3696 * Resolve the client entry information in the function
3697 silc_client_channel_message to assure that NULL pointer is not
3698 passed as client entry to the application. */
3700 * Fixed the task timeout calculation to assure that there is
3701 never negative timeouts. The affected file is
3702 lib/silcutil/silcschedule.c.
3704 * Fixed the channel user mode notification sending in server.
3705 It was sent point-to-point to the router (or to server by router)
3706 but it needs to be destined to a channel. The routines now
3707 supports sending the channel user mode notifys to the channels
3708 when announcing clients and channels. Affected files are
3709 silcd/server.c and silcd/packet_receive.c.
3711 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3712 It did not actually replace the old channel entry in the cache.
3713 Affected file lib/silcclient/client_notify.c.
3715 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Fixed a possible crash in silc_packet_send_prepare. It now
3718 assures always that there is enough space in the buffer and
3719 at the tail area of the buffer (for MAC).
3721 Fixed the inbound buffer reallocation in silc_packet_read.
3722 It was old code and did not handle the reallocation correctly.
3725 The affected file is lib/silccore/silcpacket.c.
3727 * Fixed buffer overflow in silc_parse_nickname in the file
3728 lib/silcutil/silcutil.c.
3730 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * make install generates new server keys only if there is not
3735 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3738 Added check that if the NOREPLY is set then we will not send
3739 the away message. This avoids infinite loop of away messages
3740 if both clients are away. The affected file is
3741 lib/silcclient/client_prvmsg.c.
3743 * Fixed client crash if /NICK was given without arguments.
3744 Affected file lib/silcclient/command.c.
3746 * Server does not send the invite list in INVITE command back
3747 to the client if the list was not altered. Added this notion
3748 to the protocol spec as well. Affected file silcd/command.c.
3750 Fixed possible crash in INVITE command by checking the
3751 value of silc_server_get_client_route command.
3753 * Fixed the INVITE notify type handling. The arguments are now
3754 taken in correct order and client does not crash. The affected
3755 file is irssi/src/silc/core/silc-channels.c.
3757 Removed the "Inviting xxx to channel" message from the
3758 client library away and let the application handle it.
3759 Affected file lib/silcclient/command.c. Added that message
3760 to Irssi SILC client's message formats.
3762 * Fixed CMODE command crash in client. It now checks the
3763 amount of arguments correctly and does not crash. The affected
3764 file is lib/silcclient/command.c.
3766 * Do not create new channel automatically in silc_channels_join
3767 but check whether the channel by that name already exists.
3768 Affected file irssi/silc/core/silc-channels.c.
3770 * Do not send the SERVER_SIGNOFF to router if the disconnected
3771 entity was the router. Affected file silcd/server.c.
3773 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3774 SILC client as it was missing from there.
3776 Added the handling of the KICK notify to the Irssi SILC client
3777 as it was missing. Added "you have been kicked" message to
3778 Irssi SILC client's message modules formats.
3780 Added the handing of the KILL notify to the Irssi SILC client
3781 as it was missing. Added the kill message module formats
3784 The affected file is irssi/src/silc/core/silc-channels.c.
3786 * The router did not save the channel mode the server announced.
3787 Affected file silcd/packet_receive.c.
3789 * Fixed a possible crash in INFO command in server. If the
3790 server did not provide the server info it crashed. Affected
3791 file silcd/command.c.
3793 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Fixed the GETKEY command in the server to check also the
3796 global list. Otherwise the GETKEY would not work correctly
3797 in normal SILC server. Affected file silcd/command.c.
3799 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Fixed GETKEY crash, it crashed if the command did not succseed.
3803 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3806 is now real and not just an macro interface to GMP.
3808 Removed the entire GMP from the source tree and imported new
3809 NSS MPI library instead. Reason for removing GMP is that it is
3810 extremely large and compiles extremely slow. The NSS MPI
3811 is only a few files and compiles in less than 10 seconds.
3812 The speed is also about the same as GMP. The MPI is imported
3813 to lib/silcmath/mpi.
3815 If the system has GMP installed we will still use the GMP.
3816 If it is not then the NSS MPI will be compiled.
3818 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Merged a long nickname (127 characters long) crash bugfix from
3821 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3823 * Merged a freed memory reference bugfix from Irssi CVS tree.
3824 Affected file irssi/src/core/commands.c.
3826 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Added the server's public key sving and verification to the
3829 server when performing the SKE. This was missing and the
3830 remote server's (or router's) public key was accepted without
3831 checking whether we have it previously or trust it at all.
3832 Affected file silcd/protocol.c.
3834 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Check in the silc_server_timeout_remote if protocol is active
3837 and make sure that the protocol's final callback is called so
3838 that all memory if freed. Affected file silcd/server.c.
3840 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * silc_server_whois_send_reply crashed the server if the nickname
3843 was 127 characters long. Affected file silcd/command.c.
3845 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Added sanity check to the silc_server_new_client. If the hostname
3848 is provided inside username then check that the provided hostname
3849 really is the same as the resolved one. If the hostname was not
3850 resolved then check it from the public key. Affected file is
3851 silcd/packet_receive.c.
3853 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3854 if the server disconnected us and the connection is not valid
3855 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3857 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3858 the library to the lib/silcutil/silcutil.[ch].
3860 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Close log file after open. Affected file
3863 lib/silcutil/silclog.c.
3865 * Check whether sock == NULL in silc_client_send_packet and return
3866 if it is. Affected file lib/silcclient/silcclient.c.
3868 * Check rec->entry == NULL in the Irssi SILC Client before
3869 sending the channel message. Affecte file is
3870 irssi/src/silc/core/silc-servers.c.
3872 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Merged a splitted window bugfix from Irssi CVS tree. The
3875 affected file is irssi/src/fe-text/textbuffer-view.c.
3877 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3878 It did not print nickname.
3880 * Improved the distributions system a bit.
3882 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3885 irssi/src/fe-text/gui-window.c.
3887 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3888 to in-active server. The affected file is
3889 irssi/src/silc/core/client_ops.c.
3891 * Resolve the client in USERS command reply if the entry does
3892 not have username resolved. The affected file is
3893 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3894 command to WHOIS command to really resolve stuff. The USERS
3895 is not used any more in any critical section so WHOIS can
3896 be used even though it might be slower than IDENTIFY.
3898 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3901 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Changed the protocol API a bit more consistent in the
3904 lib/silccore/silcprotocol.[ch].
3906 * Changed the following headers to ROBODoc format:
3908 lib/silccore/silcpayload.h
3909 lib/silccore/silcprotocol.h
3910 lib/silccore/silcsockconn.h
3912 All core library headers are now formatted.
3914 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3916 * Fixed a bug in Irssi SILC client; do not show that you are
3917 server/router operator if you really are not. Affected file is
3918 irssi/src/silc/core/client_ops.c.
3920 * Renamed silc_command_free_payload to silc_command_payload_free.
3921 Affected file lib/silccore/silccommand.h
3923 * Added silcmath.h to include the prototoypes of various routines
3924 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3927 * Changed the following headers to ROBODoc format:
3929 lib/silccore/silcchannel.h
3930 lib/silccore/silccommand.h
3931 lib/silccore/silcid.h
3932 lib/silccore/silcidcache.h
3933 lib/silccore/silcmode.h
3934 lib/silccore/silcnotify.h
3935 lib/silccore/silcpacket.h
3936 lib/silcmath/silcmath.h
3938 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Added checking to the server code not to start the server if
3941 ciphers and stuff are not configured properly. Affected files
3942 silcd/serverconfig.[h] and silcd/server.c.
3944 * Changed the layout of the header files of the public interfaces
3945 in the SILC libraries. The new layout supports ROBODoc
3946 documentation tool (and some others) so that it is easy to create
3947 a library reference manual. All the other headers and source
3948 code must still follow the CodingStyle document. Also source
3949 code must not include these ROBODoc stuffs, only the headers.
3950 Furthermore, all public interface headers must now be named
3951 by using `silc' prefix, example: silcapi.h, silccipher.h.
3952 Some files were renamed due to this. All the other headers
3953 must not be used as public interfaces. I will update the
3954 CodingStyle document later. Changed following headers, so far:
3956 lib/silcclient/silcapi.h
3957 lib/silccore/silcauth.h
3958 lib/silccore/silcprivate.h
3959 lib/silccrypt/silcdh.h
3961 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Removed silc_client_packet_send_flush from the client library
3966 as it is not needed. Affected file lib/silcclient/client.[ch].
3968 * Added printing of message of unresolved authentication method
3969 to the Irssi SILC client. Added it to the module formats.
3970 Removed the same message from the client library.
3972 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Added new distribution feature, DISTLABEL. Every distribution
3975 can define own preprocessor label that can be used in the
3976 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3977 file distributions, acconfig.h.pre and prepare.
3979 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Added Makefile.defines_int to include the actual definitions
3982 for Makefile.defines.in. Tested the new distribution system,
3983 created distributions and tested installation.
3985 * Added AWAY message printing to the Irssi SILC client. Added
3986 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3988 * Added SCONNECT command to call the SILC's CONNECT command.
3989 Cannot use CONNECT directly since Irssi uses that internally.
3990 Affected file irssi/src/silc/core/silc-servers.c.
3992 Added ACTION local command. It is same as ME command but takes
3993 the channel as mandatory argument.
3995 Rewrote some of the Irssi's help files to suite for SILC
3998 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Added Makefile.defines[.in] that should for now on be included
4001 in all Makefile.am file in the source tree. That file includes
4002 all common compilation definitions for SILC source tree.
4004 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Minor changes to the ./prepare script to change the package
4007 name according the distribution name to the configure.in.
4009 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Created new distribution system. Added file `distributions'
4012 that defines all the distributions that can be created out of
4013 the SILC source tree. The ./prepare script now reads that
4014 file to determine how to prepare the distributions. The
4015 first argument to the ./prepare is the name of the distribution
4016 and second is the version of the distribution. If given
4017 without arguments it creates the default (toolkit) distribution
4018 with the default version (defined in ./prepare).
4020 All Makefile.am files that are subject to the distributions
4021 are now named as Makefile.am.pre. These are ./Makefile.am
4022 and lib/Makefile.am. Others may be changed later.
4024 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Added invite list, ban list, some key management and connection
4027 error message printing to module formats in the Irssi SILC client.
4029 * Added new silc_client_set_away_message to set the away message
4030 that is back to the person who sent private message. The
4031 affected file lib/silcclient/silcapi.h and the
4032 lib/silcclient/client_prvmsg.c.
4034 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Fixed the private message sending in the Irssi SILC client,
4037 added local command KEY to the Irssi SILC client.
4039 Added key management and key agreement message formats to the
4040 irssi/src/fe-common/silc/module-formats.[ch].
4042 Added USERS (alias WHO) printing, server/router operator
4043 indication and LIST command printing to the module formats.
4045 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Fixed channel joining notify handling, cumode notify handling
4048 from Irssi SILC client.
4050 * Added SILC specific module-formats to the Irssi SILC client so
4051 that SILC specific message hilighting, colors etc is possible.
4052 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4054 Added channel mode, channel user mode, actions, notices,
4055 whois and whowas printing to the the module-formats.c.
4057 * Fixed a bug in channel deletion in the server. The channel
4058 is not left to the cache even if the channel founder auth mode
4059 is set when there are no users anymore on the channel. Affected
4060 file silcd/server.c.
4062 * The silc_net_localhost now resolves the entire hostname including
4063 the domain name. Affected file lib/silcutil/silcnet.c.
4065 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Changed the ask_passphrase client operation to be ascynchronous.
4068 It has now a completion callback and a context that the
4069 application must call after it has got the passphrase from
4070 the user. Affected files lib/silcclient/silcapi.h,
4071 lib/silcclient/protocol.c, lib/silcclient/command.c and
4074 Added SilcAskPassphrase callback that the application calls
4075 to deliver the passphrase to the library.
4077 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4078 The public key verification and especially a certificate
4079 verification is asynchronous procedure.
4081 Added new SILC_SKE_STATUS_PENDING status to indicate the
4082 request is pending and a callback will be called to finalize
4085 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4086 indicate that remote end did not send its public key (or
4087 certificate), even though we require it. Added check for this
4088 condition in the SKE. This was a security bug, now fixed.
4090 Defined new SilcSKEVerifyCbCompletion callback that is called
4091 when the verification process is completed.
4093 The affected files lib/silcske/silcske_status.h and
4094 lib/silcske/silcske.[ch].
4096 * Changed the verify_public_key client operation to be async
4097 as well. Defined SilcVerifyPublicKey callback that is used to
4098 indicate the success of the public key verification process.
4100 Changed the server and client to use the new async client
4103 * Changed the Irssi SILC client's internal scheduler to be called
4104 twice as many times as it used to be. As a result the client
4105 should be a bit faster now. Affected file is
4106 irssi/src/silc/core/silc-core.c.
4108 * Added support to Irssi SILC client of asynchronous public key
4109 verification and passphrase inquiry. Affected file is
4110 irssi/src/silc/core/silc-core.c.
4112 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Do not say "You have left channel %s" in client library.
4115 Moved it to the application. Affected files are
4116 lib/silcclient/command.c and silc/client_ops.c.
4118 * Fixed silc_client_get_clients. Command context was not
4119 duplicated and was freed memory in the callback. Affected
4120 file lib/silcclient/idlist.c.
4122 * Do not say "you are now talking..." on JOIN command in the
4123 client library. The appliation must handle it.
4125 * Do not say ".. changed topic to" in command reply in the
4126 client libary. The application must handle it.
4128 * Fixed TOPIC command sending in the client library.
4130 * Fixed a memory leak in silc_client_command_free in the file
4131 lib/silcclient/command.c.
4133 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Imported a modified version of Irssi client to the source tree.
4136 The Irssi will be used to create a new client called
4137 Irssi SILC. Imported to irssi/.
4139 Added silc_core_init_finish function to the Irssi. Affected
4140 file irssi/configure.in.
4142 A lot changes in the Makefile.ams around the irssi tree.
4144 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Do not rehash if the new size is same as the old size of the
4147 hash table, in the silc_hash_table_rehash*. The affected file
4148 lib/silcutil/silchashtable.c.
4150 * Replaced hash_table_del_by_context calls from the server
4151 (when channel->user_list and client->channels) to the
4152 hash_table_del as it is sufficient and faster.
4154 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Added silc_hash_table_list, silc_hash_table_get and the
4157 SilcHashTableList structure to provide an alternative way to
4158 traverse the hash table. The affected files are
4159 lib/silcutil/silchashtable.[ch].
4161 * Changed the server's idlist routines to use the hash table
4162 routines to optimize the code.
4164 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Replaced the client entry's `channel' list and channel entry's
4167 `user_list' list to hash tables for optimized lookup. Changed
4168 the code to use the hash table interface around the code.
4169 Affected file lib/silcd/idlist.[ch].
4171 * Added `auto_rehash' boolean argument to the function
4172 silc_hash_table_alloc to indicate whether the hash table should
4173 auto-rehash when it thinks is appropriate time. It will
4174 increase the hash table size if the there is twice as much
4175 entries in the table than the size of the table, and will
4176 decrease the size if there are twice as less entries than
4177 the size of the table.
4179 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4183 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * silc_idcache_purge_by_context deletes the entry now by context
4186 as it is supposed to do. Affected file lib/silccore/idcache.c.
4188 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4189 client is not anymore valid (WHOWAS givens the info) and not
4190 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4192 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Removed the `data' and `data_len' arguments from the ID Cache
4195 interfaces and added `name' argument. ID Cache does not handle
4196 anymore the binary data only a names associated with given ID.
4198 * When hashing a Client ID with silc_hash_id the entire ID is
4199 not hashed anymore, instead only the hash of the Client ID is
4200 hashed. This way we can access the Client ID from the cache
4201 with Client ID but with the hash of the ID (which is a hash of
4202 the nickname) as well without any difference in performance.
4204 Added also silc_idcache_find_by_id_one_ext to do one on one
4205 searching when we have the actual ID. Added also function
4206 silc_hash_client_id_compare. The affected files are
4207 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4209 * When hashing the name associated with a ID it is always done
4210 in lowercase. This way we can access the cache without worrying
4211 about case-sensitivity, even though, for example nicknames are
4214 * Fixed a bug in server with channel message sending. It put
4215 wrong ID type as destination ID. The affected file
4216 silcd/packet_send.c.
4218 * silc_idcache_del_by_context now deletes from all hash tables
4219 by context. Affected file lib/silccore/idcache.c.
4221 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Changed the client library to use the new ID Cache interface.
4224 Changes around the source tree.
4226 * Added silc_hash_table_rehash_ext to rehash with specific
4227 hash function. Affected file lib/silcutil/silchashtable.[ch].
4229 * Added silc_hash_string_compare to compare two strings in the
4230 hash table. Affected file lib/silcutil/silcutil.[ch].
4232 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Added new function silc_idcache_del_by_context into the
4235 lib/silccore/idcache.[ch].
4237 * Changed the server's ID list routines to use the new ID Cache
4238 interface. Changes around the source tree.
4240 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Added silc_hash_table_del[_by_context]_ext functions in to the
4243 lib/silcutil/silchashtable.[ch].
4245 Removed silc_hash_table_find_all* routines and added new
4246 silc_hash_table_find_foreach to replace them.
4248 Added silc_hash_table_replace_ext function as extended
4249 replacing function. Separated the simple hash table interface
4250 from the extended hash table interface in the file
4251 lib/silcutil/silchashtable.h.
4253 * Fixed minor bugs and changed it to use some of the new
4254 hash table functions in lib/silccore/idcache.c
4256 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Added new function silc_hash_table_find_all to return all keys
4259 in the hash table by the specified key. As the hash table is
4260 collision resistant it also makes it possible to have several
4261 duplicate keys in the hash table. This function may be used to
4262 find all of the keys from the hash.
4264 Added user_context arguments to the SilcHashFunction,
4265 SilcHashCompare and SilcHashDestructor to deliver user specified
4268 Added new fuctions silc_hash_table_find[_all]_ext to do
4269 extended lookup with specified hash and compare functions and
4270 specified user contexts.
4272 Added new function silc_hash_table_add_ext to add the key
4273 with specified hash function and user context.
4275 Added new function silc_hash_table_foreach to traverse all
4276 entrys in the hash table. Added SilcHashForeach callback
4279 Added new function silc_hash_table_del_by_context to delete
4280 the entry only if the context associated with the key matches.
4282 Affected files are lib/silcutil/silchashtable.[ch].
4284 * Removed silc_hash_[server/client/channel]_id and added just
4285 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4286 silc_hash_id_compare to compare two ID's using as the hash table
4287 comparison function. Added also silc_hash_data to hash
4288 binary data and silc_hash_data_compare to compare it.
4290 * Removed silc_idlist_find_client_by_hash as it is not needed
4291 anymore. Affected file silcd/idlist.[ch].
4293 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4294 to use internally the SilcHashTable. The new ID Cache is a lot
4295 faster than the old one. Some of the ID Cache interface was also
4296 rewritten and obsolete and stupid functions were removed.
4298 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Added entry_count field to the SilcHashTable to keep the number
4301 of the entries in the table. Implemented the function
4302 silc_hash_table_rehash. Added new function
4303 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4305 Fixed a minor bug in silc_hash_table_free.
4307 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4308 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4309 into the lib/silcutil/silcutil.[ch].
4311 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Implemented a collision resistant hash table into the
4314 lib/silcutil/silchashtable[ch]. See the header and the source
4315 for the SilcHashTable API.
4317 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Merged dotconf version 1.0.2 into lib/dotconf.
4321 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Do not compile anything in lib/silcsim/* if the SIM support
4324 is not enabled. The tree should now compile without problems
4327 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Compiled the SILC under cygwin. Compiled and tested briefly
4330 without problems. More tests needed. The SIMs didn't compile
4333 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4335 * Fixed possible crash in silc_get_username in the
4336 lib/silcutil/silcutil.c.
4338 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Fixed a va_arg in silc/client_ops.c.
4342 * Oops, RC5 routines were named AES and caused some problems
4343 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4345 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Added new SilcIDIP structure into the lib/silccore/id.h and
4348 replaced the old `ip' fields from all SILC ID's to that type.
4349 This is a step towards IPv6 support.
4351 The silc_id_get_len takes now the ID as an extra argument.
4352 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4353 both IPv4 and IPv6 based ID's.
4355 The affected files are lib/silccore/id.[ch] and other files
4356 around the tree using these routines.
4358 * Removed the ID length arguments in server from various
4359 silc_server_send_notify_* routines -> they are not needed
4362 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Fixed memory leak in silc_encode_pem_file in the file
4365 lib/silcutil/silcutil.c.
4367 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Check minor version as well in the SKE. Affected files are
4370 silcd/protocol.c and lib/silcclient/protocol.c.
4372 * Added --identifier option to the server so that an identifier
4373 can be when creating the public key for the server. Affected
4374 file is silcd/silcd.c.
4376 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4377 lib/silccrypt/silcpkcs.c.
4379 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Register default ciphers and stuff when using -C option with
4382 the server. Affected file sildc/silcd.c.
4384 * Put back the servers public key filename format, it is better
4385 than the new one. For now, the client keys are saved with the
4386 new filename format. The affected file silc/client_ops.c.
4388 * Implemented the Cipher API for the rest of the ciphers that
4389 did not implement it or implemented it the wrong way.
4391 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Register default ciphers and stuff when using the -S option
4394 in the client. Affected file silc/silc.c. Same also when
4395 creating new key pair with -C option.
4397 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Fixed the silc_verify_public_key client operation function to
4400 save the public keys differently. The fingerprint is now
4401 used as filename and not the hostname. This way also the
4402 client keys are saved uniquely and not with hostnames. The
4403 affected file is silc/client_ops.c.
4405 * Trimmed the silc_hash_fingerprint function to remove extra
4406 whitespaces from the end of the fingerprint. The affected
4407 file is lib/silccrypt/silchash.c.
4411 * Added silc_cipher_register_default function to register all
4412 default ciphers. It can be used when configuration files
4413 does not exist and the application does not want any specific
4414 ciphers in any specific order.
4416 The SilcDList is now used as silc_cipher_list dynamically
4417 allocated cipher list. Removed the static list all together
4418 and now all ciphers must be allocated to the dynamic list.
4419 The silc_cipher_alloc routine was changed to check only the
4422 All silc_cipher_* routines that used to return int returns
4425 The affected files lib/silccrypt/silccrypt.[ch].
4427 * The same thing was done to silc_hash_* as for silc_cipher_*
4428 routines. Affected files lib/silccrypt/silchash.[ch].
4430 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4431 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4432 Added also silc_pkcs_[un]register[_default] functions.
4433 Removed the data_context from the PKCS API.
4435 * Added silc_hmac_register_default function to register default
4436 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4437 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4438 to unregister all hmacs at once.
4440 * Register the default ciphers, hash functions, PKCSs and HMACs
4441 if client's configuration file does not exist. The affected
4444 * The client did not load the hash functions from the SIM
4445 modules at all. Added support for this. Affected file is
4446 silc/clientconfig.c.
4448 * When decoding public key with silc_pkcs_public_key_decode, check
4449 the supported algorithm only if PKCS are registered. Affected
4450 file lib/silccrypt/silcpkcs.c. The same was done with the
4451 silc_pkcs_private_key_decode.
4453 * Fixed the SILC List routines to keep the list always in order.
4454 It used to change the list's order when traversing the list but
4455 not it preserves the order. Affected file lib/trq/silclist.h.
4457 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Added the client library to use the SilcSocketConnection's
4460 reference counter (by silc_socket_dup) to prevent the bug that
4461 the socket object may be freed underneath async operation.
4463 * The name resolv library checking fixes in the configure.in.pre.
4466 * Created new version of the protocol drafts for future
4467 development. The -03 drafts are the ones that will be changed
4468 in the trunk now and the -02 will remain as they are.
4470 * Send list of CUMODE notifys to the router when announcing
4471 the channel users to the router. Affected file silcd/server.c.
4472 If the router receiving channel founder CUMODE for a channel
4473 that already has channel founder it will send CUMODE notify
4474 to the sender to remove the channel founder rights from the
4475 announced client. Affected file silcd/packet_receive.c.
4477 * The CUMODE notify may now use Server ID as well as the entity
4478 who changes the mode. Updated protocool specs.
4480 * Updated INSTALL and README files.
4482 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * New web pages in the http://silc.pspt.fi. The pages was
4489 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Implemented the [DenyConnectin] config section in the server.
4492 Added silc_server_config_denied_conn to check whether incoming
4493 connection is denied. Affected file silcd/serverconfig.[ch].
4495 * Do not check the ports when checking the incoming configuration
4496 data if the port is 0, meaning any. Affected file is
4497 silcd/serverconfig.c.
4499 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Fixed buffer overflow in silc_string_compare in the file
4502 lib/silcutil/silcutil.c.
4504 * Fixed double free in silc_server_command_leave in the file
4507 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Fixed the version checking in the server. Affected file is
4512 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Fixed the configuration data fetching when accepting new
4515 connections in the server. Affected file silcd/server.c.
4517 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Added `sender_entry' argument to the function
4520 silc_server_packet_relay_to_channel so that we can check
4521 whether some destination actually belongs to the same route
4522 the sender belongs (ie, we must not resend the packet to the
4523 sender). Affected file silcd/packet_send.[ch].
4525 * Added `servername' field to the SilcClientEntry in the server
4526 to hold the name of the server where client is from. Affected
4527 file is silcd/idlist.h.
4529 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Moved the channel message encrypting in the router betwen
4532 router connections from silc_server_channel_message to the
4533 silc_server_packet_relay_to_channel since we want to check
4534 whether we have anybody channel before encrypting anything.
4535 Affected files silcd/packet_[receive/send].c.
4537 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Fixed the [AdminConnection] server config section to support
4540 multiple entries. Affected file silcd/serverconfig.c.
4542 * Added support into the server to check the validity of the
4543 incoming connection before executing any KE or authentication
4546 * The connection configuration is now saved to the KE and
4547 connection auth protocol contexts and not fetched anymore in
4548 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4550 * The local hosts listenning address and port is also resolved
4551 now when starting the server. We want to have the socket object
4552 to include the real address and port for the listener. Added
4553 new function silc_net_check_local_by_sock into the files
4554 lib/silcutil/silcnet.[ch].
4556 * Fixed a broadcast bug in server -> do not broadcast if we
4559 * Fixed a routing bug. Do not route broadcast packets ever.
4560 Broadcast packets must be processed always and not routed since
4561 they may be destined to some other host than yourself and thus
4562 would get routed without no good reason. Affected file is
4565 * Added function silc_server_config_is_primary_route to check
4566 whether primary router connection has been configured (a router
4567 configuration that we are initiating). If there is not, we
4568 will assume that there is only two routers in the SILC network
4569 and we will use the incoming router connection as our primary
4570 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4572 * Changed the order of the broadcasting. Broadcast _after_ the
4573 packet has been processed not before. Affected file is
4576 * Fixed a [ClientConnection] parsing bug. The port was never
4577 parsed correctly thus resulting to port 0. Affected file
4578 silcd/serverconfig.c.
4580 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4581 argument and did not set the broadcast packet flag. Affected
4582 file silcd/packet_send.c. Fixed same bug in the function
4583 silc_server_send_notify as well.
4585 * If we receive NEW_ID packet for our own ID in the server, ignore
4588 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Removed the nickname from the Private Message Payload.
4593 Updated the code and the protocol specs.
4595 * Updated protocol specs for submitting to the IETF.
4597 * Tweaked the Random Number Generator a bit. Affected file
4598 lib/silccrypt/silcrng.c. Exported a new function
4599 silc_rng_[global]_add_noise which can be used to add more
4602 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Do not parse packets with different timeout when protocol
4605 is active -> may cause problem with rekey. Affected file
4608 * When server receives signoff notify it must not create
4609 new channel key if the client is on any channels since the
4610 sender of the signoff notify will create it.
4612 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Added printing of error messages during SKE protocol from the
4615 failure packet sent by server during SKE. Affected file
4618 * Removed the client's failure_callback handling with timeout
4619 and handle it immediately when received.
4621 * The SKE library returned wrong type in SUCCESS and FAILURE
4622 packets. They must be 32 bit MSB not 16 bit MSB.
4624 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Ok, rewrote the logic of the re-key and now it seems to work.
4627 I tested it on high traffic with frequent re-keys without
4628 problems. Added hmac_receive (and renamed hmac to hmac_send)
4629 in SilcClientConnection in lib/silcclient/client.h and
4630 in SilcIDListData in silcd/idlist.h. Also, removed the
4631 SilcPacketParserContext's cipher and hmac fields as they are
4632 not needed anymore and actually caused some problems when
4633 the ciphers and hmac's changed underneath the packet parser.
4635 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * If re-key protocol is active then process the incoming packets
4638 synchronously since we must assure that icoming packets encrypted
4639 with the old key is processed before the new keys is set to
4640 use. This is true other packets than for REKEY packets.
4641 Affected file silcd/server.c. The same was done to client library
4642 as well, affected file lib/silcclient/client.c.
4644 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Fixed bug in client and server to accept the force send if
4647 the packet is send from silc_[server/client]_packet_process
4648 function. Otherwise the packets are never delivered, oops.
4650 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Disable force sending of packets when REKEY protocol is active.
4653 We must assure that no packet is sent directly when rekey is
4654 performed. All packets must be sent through packet queue.
4655 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4656 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4657 function is silc_[server/client]_packet_send_real to check
4660 * Replaced the SIM paths from example config files to
4661 /usr/local/modules. Also, make install creates now
4662 /usr/local/silc/logs directory to hold all the SILC server
4665 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Made the configure.in.pre work on Solaris. Patch by salo.
4669 * Made all ciphers compatible with non-x86 machines. Defined
4670 CBC mode macros into lib/silccrypt/ciphers_def.h.
4672 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Fixed the make install.
4676 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * When MAC computation fails the silc_packet_decrypt returned 0
4679 even though it was supposed to return -1. Fixed this. The
4680 affected file is lib/silccore/silcpacket.c.
4682 * Do not replace the config files in /etc/silc (in make install)
4683 if they already exist. Affected file ./Makefile.am.
4685 * Do not send re-key packets immediately but through packet queue.
4686 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4688 * Changed silc_net_check_host_by_sock to return FALSE if the
4689 IP/DNS could not be resolved. Though, it returns the IP address
4690 now even if it could not resolve it (but returns also FALSE).
4691 Affected file lib/silcutil/silcnet.[ch].
4693 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Added silc_pkcs_decode_identifier to decode the public key's
4696 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4697 Added also silc_pkcs_free_identifier. Added also new context
4698 SilcPublicKeyIdentifier.
4700 * Added -S option to the silc client. It is used to dump the
4701 contents of the specified public key file.
4703 * Changed the PKCS api to return the public key length when
4704 setting the public key.
4706 * Fixed a fatal bug in the public and private key file loading.
4707 Affected file lib/silccrypt/silcpkcs.c.
4709 * Execute the packet parsing for client with zero (0) timeout
4710 if the protocol is active. Affected file silcd/server.c.
4712 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Made the key generation options to the silcd program. Added
4715 -C option, equivalent to client's option.
4717 * Added new [ServerKeys] config section to the server. It
4718 configures the server's public and private key.
4720 * Defined generic Public Key Payload into the protocol
4721 specification to send specific type of public keys and
4724 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4725 public key or certificate.
4727 * Implemented the GETKEY command to the server and to the
4728 client library and on user interface.
4730 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Made preliminary `make install' work.
4734 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Added SilcServerRekey context into silcd/idlist.h.
4738 * Added the PFS support as defined in the specification to the
4739 SKE protocol. Affected files lib/silcske/*.c.
4741 * Added `ske_group' field to the SilcServerRekey context to hold
4742 the number of the SKE group that is used with PFS in re-key.
4743 Affected file silcd/idlist.h.
4745 * Added PFS re-key support to the server. Affected file is
4748 * Added silc_protocol_cancel to cancel execution of the next
4749 state of the protocol. Affected file is
4750 lib/silccore/silcprotocol.[ch].
4752 * Added the re-key support with and without PFS to the client
4753 library. Re-key is performed once in an hour, by default.
4755 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4756 Added silc_client_rekey_callback and silc_client_rekey_final.
4757 Affected files are lib/silcclient/protocol.[ch] and
4758 lib/silcclient/client.[ch].
4760 * Removed the `hmac_key' and `hmac_key_len' fields from the
4761 SilcClientConnection structure; not needed. Affected file is
4762 lib/silcclient/client.h.
4766 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Do not ask whether user wants to use the negotiated private key
4769 for private messages, just use it. Affected file is
4770 silc/local_command.c.
4772 * Added `send_enc_key' and `enc_key_len' fields to the
4773 SilcIDListData structure since they are needed in the re-key
4774 phase. Affected file is silcd/idlist.[ch].
4776 * Implemented the simple re-key protocol into the server.
4777 Affected files silcd/server.c and silcd/protocol.[ch]. The
4778 re-key will be performed once in an hour, by default.
4780 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4781 Added silc_server_rekey, silc_server_rekey_callback and
4782 silc_server_rekey_final.
4784 * Removed Tunneled flag from the protocol. Updated the code
4785 and the specifications.
4787 * Adde `pfs' field to the SilcIDListData to indicate whether
4788 the PFS is to be performed in the re-key. Affected file is
4791 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4794 int64 of at least the xintXX size. If void * is less that 4
4795 bytes uint32 * will be used. Defined bool as boolean.
4797 * Changed _ALL_ unsigned long and unsigned int to uint32,
4798 unsgined short to uint16 in the source tree.
4800 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4801 not handle clients that has entry->data.registered == FALSE.
4802 They are not in the network anymore. Affected file is
4805 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Implemented the sending of the SERVER_SIGNOFF notify in the
4808 server. Affected file is silcd/server.c.
4810 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4811 Added also silc_notify_payload_encode_args into the
4812 lib/silccore/silcnotify.[ch].
4814 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4815 Affected file silcd/packet_receive.c.
4817 * Implemented the SERVER_SIGNOFF notify handling in the client
4818 library. Affected file lib/silcclient/client_notify.c. Also,
4819 implemnted the printing of the SERVER_SIGNOFF info to the
4820 application. Affected file silc/client_ops.c.
4822 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4823 if the deleting was successful. Affected file silcd/idlist.[ch].
4825 * Added support for public key authentication in the connection
4826 authentication protocol in the client library. Affected file
4827 lib/silcclient/protocol.c.
4829 * Changed the server's silc_idlist_get_clients_by_* interface
4830 to support already allocated array so that new entries may be
4831 added to pre-allocated array. Affected file silcd/idlist.[ch].
4832 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4833 and command replies.
4835 * All command reply functions in the server now calls the
4836 pending command callback even if error occured. This way the
4837 error will be delivered to the client as well. Affected files
4838 silcd/command.c and silcd/command_reply.c.
4840 * Fixed INFO command to return local server's info if no server
4841 was provided. Affected file lib/silcclient/command.c.
4843 * Removed RESTART command for good. Updated the code and the
4846 * Rewrote parts of the task system. It is a bit simpler now.
4847 Removed unsued task priorities. The affected files are
4848 lib/silcutil/silctask.[ch].
4850 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Moved the USERS printing from the library to the application.
4853 Affected files lib/silcclient/command.c and silc/client_ops.c.
4855 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Added channel key re-key support. The re-key is perfomed
4860 only by the router and is done once in an hour. Added `rekey'
4861 field to the SilcChannelEntry in the server. Affected files
4862 silcd/server.c and silcd/idlist.h.
4864 * Added silc_task_unregister_by_context into the file
4865 lib/silcutil/silctask.[ch].
4867 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Added SILC_UMODE_GONE mode to indicate when the client is not
4870 present in the SILC network. Added also support to the local
4871 command AWAY that will set this mode. Added support of showing
4872 "xxx is gone" in WHOIS command. The USERS command shows the
4873 gone status as well.
4875 * Fixed setting server and router operator privileges in the
4876 server's UMODE command. Affected file silcd/command.c.
4878 * Merged the SKE KE1 and KE2 payloads into one payload. The
4879 new KE payload is equivalent to the old KE2 payload.
4881 Cleaned up the SKE Start Payload parsing. It now uses the
4882 simple buffer unformatting to do the parsing. A lot faster
4885 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4886 to the SKE that is used to indicate whether both of the SKE
4887 parties should perform authentication. By default only the
4888 responder performs authentication. By setting this flag also
4889 the initiator must do authentication. By default it is unset
4890 since in normal SKE case, client to server connection, only
4891 the responder should do authentication. When doing SKE between
4892 two clients both should perform authentication. Updated the
4893 code and the protocol specs.
4895 * A little fix to IDENTIFY command in the server. Search the
4896 client first by hash not nickname. Affected file is
4899 * Fixed the silc_client_close_connection to support closing
4900 the client to client connections wihtout deleting too much
4901 data. Affected file lib/silcclient/client.c.
4903 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4904 are received if protocol used to be active but is not anymore
4905 the application would crash due to NULL pointer dereference.
4906 Affected files silcd/server.c and lib/silcclient/client.c.
4908 * Added `hash' field to the SilcClientConnection to include
4909 the hash function negotiated in the SKE protocol.
4911 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4912 to set the channel founder authentication data. A client can
4913 claim the founder rights later by providing the authentication
4914 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4915 This way the channel founder can regain the channel founder
4916 privileges even it is left the channel. This works only on
4917 local server and the client must be connected to the same
4918 server to be able to regain the founder rights. Updated the
4919 protocol specs accordingly.
4921 Added support to the CMODE command in the client to set the
4922 founder auth data. Read the README to see how to set it.
4924 Added support to the CUMODE command to claim the founder
4925 rights. Read the README to see how to do it.
4927 Added support for the founder authentication to the Channel
4928 Entry in the server. Affected file silcd/idlist.h.
4930 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4931 server's CMODE command. Affected file silcd/command.c.
4933 * Added the following new functions into lib/silccore/silcauth.[ch]:
4934 silc_auth_get_method and silc_auth_get_data.
4936 * The server now saves the remote hosts public key to the
4937 SilcIDListData pointer. Affected file silcd/protocol.c.
4939 * The normal server now does not remove the channel entry from
4940 the cache if the founder authentication data is set. It used
4941 to remove it if the founder was the last one on the channel on
4942 the server and left the channel. The auth data is saved and
4943 if the channel is re-joined later the old entry is used with
4944 the old auth data. Affected files silcd/command_reply.c and
4947 * Removed the `pkcs' field from the SilcIDListData structure
4948 in the server; it is not used. Affected file silcd/idlist.h.
4950 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Fixed packet processing on slow links. Partial packets were
4953 never re-processed because the incoming data buffer was cleared
4954 by the application. Application must not directly clear the
4955 sock->inbuf, the packet processing routines handle it. Fixed
4956 this in client library and in server.
4958 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Fixed the WHOIS and IDENTIFY send reply function to really
4961 check whether to send list or just one entry. Affected file
4964 * Cleaned up the LEAVE command's channel key distribution. The
4965 affected file silcd/command.c.
4967 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4968 can enforce the channel mode as well. In that case the ID
4969 includes the ID of the server. The code now enforces the
4970 mode change if the router have different mode than the server.
4972 * The notify client operation with CMODE_CHANGE notify can now
4973 return NULL client_entry pointer if the CMODE was not changed
4974 by client. Application must check for this.
4976 * Added <Server ID> argument to INFO command to support server
4977 info fetching by Server ID.
4979 * Added silc_server_announce_get_channel_users to get assembled
4980 packets of channel users of the specified channel. Affected
4981 file silcd/server.[ch].
4983 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4984 was freed underneath the ID Cache.
4986 * Re-announce clients when the server received CHANNEL_CHANGE
4987 notify from the router. Affected file silcd/packet_send.c.
4989 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4992 crashed since it did not handle the fact that there is no cipher
4993 called "3" and didn't check the error condition. Now fixed.
4995 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4996 flag. It can be used to send message requests.
4998 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Implemented the RESTART command in the client.
5002 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5003 notice type messages. Added notice printing to the user
5006 * The channel keys are not re-generated if the channel's mode
5007 is PRIVKEY, ie private key on the channel exists. Affected
5008 files silcd/server.c and silcd/command.c.
5010 * Fixed a little bug in channel message delivery when channel
5011 private keys are set in the server. Affected file is
5012 silcd/packet_send.c.
5014 * Changed the setting on channel->on_channel = TRUE from the
5015 silc_client_save_channel_key to the JOIN command reply. The
5016 key payload is not received if the private channel key is set.
5017 Affected file lib/silcclient/command_reply.c and the
5018 lib/silcclient/client_channel.c.
5020 * When the CMODE_CHANGE notify is sent and the channel private
5021 key mode is removed the channel key must be re-generated in
5022 other cells as well. Added this support for the router in the
5023 silcd/packet_receive.c.
5025 * Added new local command NOTICE to send notice message on
5026 channel. Affected file silc/local_command.[ch].
5028 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added new local command ME to the client. It is used to send
5031 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5032 some action. Affected file silc/local_command.[ch].
5034 * Changed channel_message and private_message client operations
5035 to deliver the message flags to the application. Added also
5036 the `flags' arguments to the silc_client_send_channel_message
5037 and silc_client_send_private_message functions. Affected file
5040 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Redefined the Private Message Payload to support private message
5043 keys and to support the new private message flags. Updated
5044 the protocol specs. Flags makes it possible to have for example
5045 CTCP style messages.
5047 * Added new type SilcPrivateMessagePayload and defined an API
5048 for it in the lib/silcclient/silcprivate.[ch].
5050 * Tested private message private keys successfully. Tested the
5051 private message key set, unset and list commands with the new
5054 * Redefined the Channel Message Payload to include the channel
5055 message flags (equal with private message flags) to support
5056 for example CTCP style messages.
5058 * Defined some of the message (for channel and private message)
5059 flags. Updated the protocol specs and added the flags to the
5060 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5062 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Added SilcKeyAgreementStatus type to the key agreement routines
5065 to indicate the current status and error if one occured.
5066 The status types are defined in the lib/silcclient/silcapi.h.
5068 * Added new local command KEY that is used to set and unset private
5069 keys for channels, set and unset private keys for private messages
5070 with remote clients and to send key agreement requests and
5071 negotiate the key agreement protocol with remote client. The
5072 key agreement is supported only to negotiate private message keys,
5073 it currently cannot be used to negotiate private keys for channels,
5074 as it is not convenient for that purpose.
5076 * Fixed a minor pending callback setting bug in the function
5077 silc_client_get_client_by_id_resolve, now the function works.
5078 Affected file lib/silcclient/idlist.c.
5080 * Added function silc_net_get_local_port to get local bound
5081 port by socket. Added to lib/silcutil/silcnet.[ch].
5083 * Added `sockets' and `sockets_count' fields to the SilcClient
5084 object. They hold the sockets of the listenning sockets in
5085 the client. Listenning sockets may be for example the key
5086 agreement server. Affected file lib/silcclient/client.[ch].
5087 Added functions the silc_client_add_socket and the
5088 silc_client_del_socket. They are exported to the application
5091 * Added ~./silc/clientkeys to support other client's public keys.
5093 * Renamed verify_server_key client operation to verify_public_key
5094 and added one argument to indicate the type of the connection
5095 (server, client etc.).
5097 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Added silc_server_connection_auth_request to handle the
5100 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5101 silcd/packet_receive.[ch].
5103 * Added silc_server_send_connection_auth_request into the
5104 silcd/packet_send.c to send the connection auth request packet.
5106 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5109 * Fixed the public key authentication in responder side in the
5110 server. The `auth_data' pointer includes the SilcPublicKey
5111 not the path to the public key. Affected file silcd/protocol.c.
5113 * Implemented the public key authentication in the initiator side
5114 in the server. Affected file silcd/protocol.c.
5116 * Removed the [RedirectClient] config section from the server
5117 configuration. Is not needed and I don't want to implement it.
5119 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Cleaned up the CMODE command in the server. It now works
5122 correctly and supports all the modes defined in the protocol.
5123 Affected file is silcd/command.c.
5125 * Added `hmac_name' field to the SilcChannelEntry in the server
5126 to hold the default HMAC of the channel. It can be set when
5127 creating the channel (with JOIN command). Affected files
5130 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5131 type to indicate the change of the current cipher and hmac
5132 on the channel. Client can safely ignore the <cipher> argument
5133 (if it chooses to do so) since the CHANNEL_KEY packet will
5134 force the channel key change anyway. The <hmac> argument is
5135 important since the client is responsible of setting the new
5136 HMAC and the hmac key into use.
5138 * Fixed the CMODE command in the client library as well.
5140 * Tested CMODE command in router environment successfully.
5142 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Show the version of the remote client (or server) when connecting
5145 to the server. It is logged to the log file. Affected file
5146 is silcd/protocol.c.
5148 * Fixed the KILLED notify handling in the client library. The
5149 client must be removed from all channels when receiving the
5152 Also, do not remove the client entry when giving the KILL
5153 command but when the KILLED notify is received.
5155 * Removed silc_idlist_find_client_by_nickname from the server.
5156 Not needed anymore. Affected files silcd/idlist.[ch].
5158 * Implemented the CHANNEL_CHANGE notify type handling to the
5159 server. Affected file silcd/server.c.
5163 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Added silc_server_send_notify_invite to send the INVITE
5166 notify between routers.
5168 * Implemented the INVITE command correctly to the server.
5170 * Implemented the INVITE notify type handling in the server.
5172 * Implemented the INVITE command to the client library and on the
5175 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Added function silc_server_get_client_resolve to find the
5178 client entry by ID from all ID lists and then resolve it
5179 (using WHOIS) if it cannot be found. Affected file is
5182 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Implemented the BAN command to the client library.
5186 * The JOIN command in the server now checks the invite list
5189 * Changed the silc_command_reply_payload_encode_va and the
5190 silc_command_payload_encode_va to support that if argument is
5191 NULL it ignores and checks the next argument. Affected file
5192 lib/silccore/silccommand.c.
5194 * Added silc_server_send_notify_ban to send the BAN notify
5195 type between routers.
5197 * Chaned the silc_notify_payload_encode to support that if
5198 argument is NULL it ignores and checks the next argument.
5199 Affected file lib/silccore/silcnotify.c.
5201 * Tested ban lists in router environment successfully.
5203 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Implemented BAN command to the server, in silcd/command.[ch].
5207 * Removed the BAN and INVITE_LIST modes from the CMODE command
5210 * Added function silc_string_match to regex match two strings.
5211 Affected files lib/silcutil/silcutil.[ch].
5213 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Redefined parts of the SilcChannelEntry in the server to support
5216 the new ban and invite lists.
5218 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Redefined the INVITE command. The same command can be used to
5221 invite individuals to the channel but also to manage the invite
5222 list of the channel (to add to and remove from the invite list).
5223 Updated the protocol specs.
5225 * Added new command SILC_COMMAND_BAN that can be used to manage
5226 the ban list of the channel. Updated the protocol specs.
5228 * Removed the channel modes: the SILC_CMODE_BAN and the
5229 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5230 in the CMODE command. The equivalent features are now available
5231 using INVITE and BAN commands. Updated the protocol specs.
5233 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5234 in the network about change in the current ban list. The notify
5235 type is not used by the client.
5237 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5238 support the invite lists.
5240 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Added new function silc_string_regexify that converts string
5243 including wildcard characters into regex string that can
5244 be used by the GNU regex library. Added into the file
5245 lib/silcutil/silcutil.[ch].
5247 Added silc_string_regex_combine to combine to regex strings
5248 into one so that they can be used as one regex string by
5249 the GNU regex library. Added into the file
5250 lib/silcutil/silcutil.[ch].
5252 Added silc_string_regex_match to match two strings. It returns
5253 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5255 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Imported GNU regex to the soruce tree into lib/contrib.
5258 Fixed some compiler warning from the regex.c.
5260 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Fixed MOTD command in the server to work in router environment.
5264 * Fixed the MOTD command in the client library to support
5265 the server argument in the command.
5267 * Added `nickname_len' argument to the silc_idlist_add_client
5268 in the server, as the `nickname' argument may be binary data
5271 * Added silc_idlist_get_channels to return all channels from
5274 * Implemented LIST command to the server. Affected file is
5277 * Implemented the LIST command to the client library and on the
5280 * Added [<user count>] argument to the LIST command reply.
5281 With private channels the user count is not shown.
5283 * Updated TODO and README.
5285 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * The client entry's data.registered must be TRUE even with
5288 global client entry on global client list. The data.registered
5289 is used to check whether the client is anymore in the network,
5290 for example with WHOWAS command so it must be valid.
5292 * Fixed the WHOWAS command in the server. It now actually works
5293 in router environment. Added function into silcd/command_reply.c
5294 silc_server_command_reply_whowas_save.
5296 * Added silc_idlist_purge function to the silcd/idlist.c
5297 to periodically purge the ID Cache.
5299 * Fixed INFO command in the server. It works now in router
5300 environment. Added <server name> argument to the INFO command
5301 reply. Updated the protocol specs.
5303 * Fixed minor bug in silc_idcache_purge to not purge if the
5304 expire value is zero.
5306 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5307 they were buggy because of the WHOWAS information.
5309 * Fixed local command MSG to handle the async resolving of
5310 the remote client properly. It used to fail the first MSG.
5311 Affected file silc/local_command.c.
5313 * Added `data_len' field to SilcIDCache context.
5315 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * Update TODO. Todo in commands in the server.
5319 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5322 used by routers as broadcast packet to inform other routers
5323 about the changed user mode.
5325 Implemented the notify handling in the server. Affected file is
5326 silcd/packet_receive.c. Added the function
5327 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5329 * Added new generic Channel Payload and deprecated the New Channel
5330 Payload. The New Channel Payload is now the generic Channel
5333 * Added new argument `mode' to the silc_server_send_new_channel
5334 as it is required in the Channel Payload now.
5336 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5337 and created a new and real SilChannelPayload to represent the
5338 new generic Channel Payload. Implemented the encode/decode
5339 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5341 * Added silc_server_get_client_channel_list to return the list
5342 of channels the client has joined for WHOIS command reply.
5343 Affected file silcd/server.[ch].
5345 * Implemented the channel list sending in the WHOIS command reply
5346 in server and in the client.
5348 Implemented the channel list displaying on the user interface
5349 as well. Affected file silc/client_ops.c.
5351 * Added silc_channel_payload_parse_list to parse list of Channel
5352 Payloads. It returns SilcDList list of SilcChannelPayloads.
5353 Client for example can use this function to parse the list of
5354 channels it receives in the WHOIS command reply. The caller
5355 must free the list by calling silc_channel_payload_list_free.
5356 Affected files lib/silccore/silcchannel.[ch].
5358 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Added one new argument <user mode> to the WHOIS command reply
5361 to return the mode of the user in SILC. Updated the protocol
5364 Implemented it to the server and client.
5366 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Fixed the mode printing on the user interface on joining.
5369 Affected file silc/client_ops.c.
5371 * Implemented the UMODE command and user modes in general to the
5372 client library and to the user interface.
5374 * Implemented the UMODE command to the server.
5376 * The server now sends UNKNOWN_COMMAND error status if client sends
5377 unknown command. Affected file silcd/command.c.
5379 * All server commands now handle the command identifier the right
5380 way when sending the command reply to the client. The client can
5381 use to identify the command replies with the identifier.
5383 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Added silc_server_get_client_route to resolve the route to
5386 the client indicated by the client ID. Affected file is
5389 * Added silc_server_relay_packet as general function to relay
5390 packet to arbitrary destination. This deprecates functions
5391 like _send_private_message_key, _relay_notify etc. Affected
5392 file is silcd/packet_send.[ch].
5394 Removed silc_server_send_key_agreement,
5395 silc_server_send_private_message_key and
5396 silc_server_packet_relay_notify functions from the file
5397 silcd/packet_send.[ch].
5401 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5402 server. Affected file silcd/packet_receive.[ch].
5404 * Implemented the KILL command to the client. Implemented the
5405 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5406 Affected files lib/silcclient/command[_reply].c and
5407 lib/silcclient/client_notify.c. Implemented the KILL notify
5408 printing in the user inteface.
5410 * Fixed a lot silc_parse_nick memory leaks from the client
5411 library in the file lib/silcclient/command.c.
5413 * Changed the silc_server_send_notify_on_channels's `sender'
5414 argument from SilcSocketConnection to SilcClientEntry to
5415 check the sender as entry and not as connection object and not
5416 to send to the client provided as argument. The affected file
5417 is silcd/packet_send.[ch].
5419 * The notify packets that are destined directly to the client used
5420 to not to be processed by the server. Now changed that and the
5421 server processes all notify packets. After relaying the packet
5422 to the client the notify packet is processed in the server.
5424 * The silc_server_free_client_data now checks whether there is
5425 pending outgoing traffic for the client and purges the data to
5426 the network before removing the client entry.
5428 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5431 an client is killed from the SILC Network. Updated the protocol
5434 Added new function silc_server_send_notify_killed to the
5435 silcd/packet_send.[ch].
5437 * Added function silc_server_packet_relay_notify to relay notify
5438 packets that are destined directly to a client. In this case
5439 the server does not process the notify packets but merely relays
5440 it to the client. Affected file silcd/packet_send.[ch].
5442 Added also silc_server_packet_process_relay_notify to check
5443 whereto relay the notify. Affected file is
5444 silcd/packet_receive.[ch].
5446 * Implemented the KILL command to the server.
5450 * Added the backup schema desgined last fall to the protocol
5451 specs for everyone to see. The specification is in the
5452 *-spec-xx.txt draft and the packet type definitions for the
5453 backup routers is in *-pp-xx.txt draft. Thusly, added also
5454 new packet type SILC_PACKET_CELL_ROUTERS.
5456 * A big security problem in the implementation discovered. The
5457 signoff of an client did not cause new channel key generation
5458 which it of course should've done. The channel keys must be
5459 always re-generated when client leaves (or signoffs) the channel.
5460 The silc_server_remove_from_channels funtion now handles
5461 the channel key re-generation.
5463 * Added `sender' argument to the silc_server_send_notify_on_channels
5464 to not to send the client provided as argument. Affected file
5465 silcd/packet_send.[ch].
5467 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Implemented OPER and SILCOPER commands into the server and
5472 * Added silc_auth_verify and silc_auth_verify_data to verify
5473 the authentication directly from the authentication payload.
5474 It supports verifying both passphrase and public key based
5475 authentication. Affected file lib/silccore/silcauth.[ch].
5477 * Added `hash' field to the SilcIDListData structure. It is the
5478 hash negotiated in the SKE protocol. Affected file is
5481 * Slight redesigning of the SilcAuthPayload handling routines.
5482 Do not send SilcPKCS but SilcPublicKey as argument.
5484 * Implemented the public key authentication support to the
5485 serverconfig. The public key is loaded from the provided path
5486 and saved as authentication data to void * pointer. Thus,
5487 changed the unsigned char *auth_data to void *auth_data;
5489 * Fixed SHUTDOWN command to send the reply before the server
5490 is shutdown. :) Affected file silcd/command.c.
5492 * Fixed fatal bug in CONNECT command. The hostname was invalid
5493 memory and server crashed. Affected file silcd/command.c.
5495 * Fixed fatal bug in CLOSE command. The server_entry became
5496 invalid but was referenced later in the command. Affected file
5499 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Fixed fatal bug in failure packet handling. Server ignored
5502 the failure and thus crashed when it came.
5506 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5509 that the command may be executed only once in (about) 2 seconds.
5510 The old SILC_CF_LAG flag is same but allows command bursts up
5511 to five before limiting.
5513 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5514 server code. Various commands now includes the CF_LAG_STRICT
5515 flag to disallow any kind of miss-use of the command.
5517 * Fixed the silc_buffer_unformat to not to allocate any data
5518 if the length of the data is zero. It used to allocate the
5519 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5521 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Changed the format of AdminConnection configuration section
5524 in the server. Added username of the admin to the format.
5525 Affected files silcd/serverconfig.[ch].
5527 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5528 to return admin configuration data by host, username and/or
5531 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Implemented WHOWAS command to the server. Added the functions:
5535 silc_server_command_whowas_parse,
5536 silc_server_command_whowas_send_reply,
5537 silc_server_command_whowas_from_client and
5538 silc_server_command_whowas_from_server
5540 * Added <Client ID> argument to the WHOWAS command reply. Updated
5541 the protocol specs accordingly.
5543 * Implemented WHOWAS command and command_reply to the client
5546 Implemented the WHOWAS printing on the user interface.
5548 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Added new argument to the WHOWAS command reply, the real name.
5551 It is an optional argument. Updated the protocol specs.
5553 * Added SilcIDCacheDestructor callback that is registered when
5554 the SilcIDCache is allocated. The callback is called when
5555 an cache entry in the ID Cache expires, or is purged from the
5556 cache. Added into lib/silccore/idcache.[ch].
5558 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5559 to destruct the client entries when the cache entry expires.
5560 Other ID Cache's in server and in the client library ignores
5563 * If the ID Cache entry's `expire' field is zero then the entry
5564 never expires. Added boolean `expire' argument to the
5565 silc_idcache_add function in the lib/silccore/idcache.[ch].
5566 If it is TRUE the default expiry value is used.
5568 * Added silc_server_free_client_data_timeout that is registered
5569 when client disconnects. By default for 5 minutes we preserve
5570 the client entry for history - for WHOWAS command.
5572 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Added support to the server to enforce that commands are not
5575 executed more than once in 2 seconds. If server receives
5576 commands from client more frequently, timeout is registered
5577 to process the commands. Affected file silcd/command.c.
5578 Added new function silc_server_command_process_timeout.
5580 * Changed NICK_NOTIFY handling in client library to check that
5581 if the client's nickname was changed, so there is no need to
5582 resolve anything from the server.
5584 * Removed error printing from the WHOIS and IDENTIFY commands.
5585 If error occurs then it is ignored silently in the client library.
5586 The application, however, may map the received error to
5587 human readable error string. The application currently maps
5588 the NO_SUCH_NICKNAME error to string.
5590 * Made the command status message public to the application. Moved
5591 them from lib/silcclient/command_reply.c to
5592 lib/silcclient/command_reply.h. The application can map the
5593 received command status to the string with the
5594 silc_client_command_status_message function.
5596 * Added check to the server to check that client's ID is same
5597 as the Source ID in the packet the client sent. They must
5600 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added dist-bzip hook to the Makefile.am to make bzip2
5603 compressed distributions.
5605 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Server now enforces the maximum length for the nickname and
5608 the channel as protocol specification dictates. 128 bytes for
5609 nickname and 256 bytes for channel name.
5611 * Moved the WHOIS printing to the application. The client libary
5612 does not print out the WHOIS information anymore, the application
5613 must do it. Renamed silc_client_command_reply_whois_print to
5614 the silc_client_command_reply_whois_save.
5616 The client's idle time is also sent to the application now, and
5617 the idle is shown on screen.
5619 * Added silc_client_command_reply_identify_save to save the
5620 received IDENTIFY entries.
5622 * Do not check for channel private keys in message sending and
5623 reception if the channel does not have the PRIVKEY mode set.
5624 Affected file lib/silclient/client_channel.c.
5626 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5629 just surfaced after chaning the JOIN procedure.
5631 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Added silc_client_get_clients_by_list to get client entries
5634 from Client ID list, that is returned for example by JOIN
5635 and USERS command replies. The application should use this
5636 function for example when JOIN command reply is received to
5637 resolve the clients already on the channel (library does not
5638 do that anymore as USERS command reply is not used in the JOIN
5639 procedure anymore). Affected files lib/silcclient/silcapi.h and
5640 lib/silcclient/idlist.c.
5642 * JOIN command reply and USERS command reply returns now SilcBuffer
5643 pointers instead of unsigned char pointers when returning
5644 the client list and mode list.
5646 * Added <Client ID> argument to the JOIN command reply, mainly
5647 for the server to identify for which client the command was
5648 originally sent. Updated protocol specs accordingly.
5650 * Added SilcDlist private_key pointer to the SilcChannelEntry
5651 in the client to support the channel private keys. Affected
5652 file is lib/silcclient/idlist.h.
5654 * Added SilcChannelPrivateKey argument to the function
5655 silc_client_send_channel_message so that application can choose
5656 to use specific private ke if it wants to. If it is not provided,
5657 the normal channel key is used, unless private keys are set.
5658 In this case the first (key that was added first) is used
5659 as the encryption key.
5661 * Implemented the support for channel private key handling.
5662 Implemented the following functions:
5664 silc_client_add_channel_private_key,
5665 silc_client_del_channel_private_keys,
5666 silc_client_del_channel_private_key,
5667 silc_client_list_channel_private_keys and
5668 silc_client_free_channel_private_keys
5670 Affected file lib/silcclient/client_channel.c.
5672 * Added the support for the private keys in the channel message
5673 sending and encryption and in the message reception and
5674 decryption. Affected funtions are
5675 silc_client_send_channel_message and silc_client_channel_message.
5677 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Added SKE's key verify callback to the client library's
5680 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5682 * Removed the statement that server (or router) must send USERS
5683 command reply when joining to the channel so that the client
5684 knows who are on the channel. Instead, the client list and
5685 client's mode list is now sent in the JOIN command reply to the
5686 client who joined channel. This is better solution.
5688 * Added function silc_server_get_users_on_channel and function
5689 silc_server_save_users_on_channel to the silcd/server.[ch].
5691 * Removed function silc_server_command_send_users from the
5694 * Do not show topic on the client library anymore. The topic is
5695 sent in the command reply notify to the application and the
5696 application must show the topic now.
5698 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Added client searching by nickname hash into the IDENTIFY and
5701 WHOIS commands in the server as they were clearly missing from
5702 them. Affected file is silcd/command.c.
5704 * Fixed a bug in private message receiving in the client library.
5705 The remote ID was freed and it wasn't supposed, now it is
5708 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Minor fix to the channel payload; allocate the data area, as it
5711 needs to be of specific length.
5713 * If the key agreement port is zero then the operating
5714 system will define the bound port. Affected files are
5715 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5717 * Added new function silc_channel_payload_decrypt into the file
5718 lib/silccore/silcchannel.[ch].
5720 * Moved the channel message etc, check from silc_packet_decrypt
5721 to applications. The library calls now a generic
5722 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5723 when the packet is either normal or special. This was done to
5724 allow more wide range of checking that was not allowed when
5725 the code was in library. Now applications can do virtually any
5726 checks to the packet and return to the library the decision how
5727 the packet should be processed. Affected files are
5728 lib/silccore/silcpacket.[ch].
5730 Added silc_server_packet_decrypt_check to the server and
5731 silc_client_packet_decrypt_check to the client library.
5733 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5734 to send with specified source and destination information.
5736 * Channel message delivery between routers was broken after the
5737 channel key distribution was fixed earlier. The channel key
5738 was used be to distributed to other routers as well which is not
5739 allowed by the protocol. Now this is fixed and channel keys
5740 really are cell specific and the channel message delivery between
5741 routers comply with the protocol specification.
5743 * Fixed various commands in server to check also the global list
5744 for the channel entry and not just the local list. The affected
5745 file silcd/command.c.
5747 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Added assert()s to buffer formatting and unformatting routines
5750 to assert (if --enable-debug) when error occurs. Affected
5751 file: lib/silcutil/silcbuffmt.c.
5753 * Changed to auto-reconnect to check whether the remote host is
5754 router and register the re-connect timeout if it is. It used
5755 to check that whether we are normal server, but router must do
5756 auto-reconnect with another router as well. Affected file
5759 * Removed the [<key len>] option from CMODE command as the cipher
5760 name decides the key length, nowadays. See the defined ciphers
5761 from the protocol specification.
5763 * Added [<hmac>] option to the CMODE command to define the HMAC
5764 for the channel. Added SILC_CMODE_HMAC channel mode.
5766 * Added [<hmac>] option for the JOIN command so that user can
5767 select which HMAC is used to compute the MACs of the channel
5770 * Added Hmac field to the Channel Message Payload. The integrity
5771 of plaintext channel messages are now protected by computing
5772 MAC of the message and attaching the MAC to the payload. The
5773 MAC is encrypted. Now, it is clear that this causes some
5774 overhead to the size of the packet but rationale for this is that
5775 now the receiver can verify whether the channel message decrypted
5776 correctly and also when private keys are set for the channel the
5777 receiver can decrypt the packet with several keys and check from
5778 the MAC which key decrypted the message correctly.
5780 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5781 lib/silccrypt/silccipher.[ch].
5783 * Added silc_hash_len to return the digest length into the
5784 lib/silcrypt/silchash.[ch].
5786 * Rewrote parts of Silc Channel Payload interface in the
5787 lib/silccore/silcchannel.[ch]. The encode function now also
5788 encrypts the packet and parse function decrypts it.
5790 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Fixed a minor formatting bug in the SKE's key material processing.
5793 It actually might have processed the keys wrong way resulting
5796 * Redefined the mandatory HMAC algorithms and added new algorithms.
5797 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5798 and hmac-md5 truncated to 96 bits. The mandatory is now
5799 hmac-sha1-96. Rest are optional (including the one that used
5800 to be mandatory). Rationale for this is that the truncated HMAC
5801 length is sufficient from security point of view and can actually
5802 make the attack against the HMAC harder. Also, the truncated
5803 HMAC causes less overhead to the packets. See the RFC2104 for
5806 * Added new [hmac] configuration section. The SKE used to use
5807 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5808 is of course wrong. The official names that must be proposed in
5809 the SKE are the ones defined in the protocol specification
5810 (hmac-sha1-96 for example). The user can configure any hmac
5811 using any hash function configured in the [hash] section. At
5812 least, the mandatory must be configured.
5814 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5816 * Added HMAC list to the SKE proposal list. It has now both
5817 hash algorithm list and HMAC list. This makes the protocol
5818 incompatible with previous versions. The SKE now seems to work
5819 the way it is supposed to work, for the first time actually.
5821 * Defined plain Hash algorithms to the protocol specification.
5824 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Implemented support for key agreement packets into the server.
5827 Added functions silc_server_key_agreement and
5828 silc_server_send_key_agreement. Other than these functions,
5829 server has nothing to do with this packet.
5831 * Added support for private message key packets into the server.
5832 Added functions silc_server_private_message_key and
5833 silc_server_send_private_message_key.
5837 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5838 called in the protocol's final callback instead in the END
5839 protocol state. This makes a little more sense and in the same
5840 time in client we can use the same protocol routines for normal
5841 key exchange and to key agreement packet handling as well.
5843 * Added to both client's and server's KE protocol context the
5844 SilcSKEKeyMaterial pointer to save the key material. We will
5845 bring the key material to the protocol's final callback by doing
5846 this. The final callback must free the key material.
5848 * Added SKE's packet_send callback into client's KE protocol
5849 context so that the caller can choose what packet sending function
5850 is used. This way we can use different packet sending when
5851 doing normal SKE when doing key agreement packet handling (in
5852 the key agreement packet handling we do not want to encrypt
5855 * Implemented the responder side of the key agreement routines
5856 in the client. The client can now bind to specified port and
5857 accept incoming key negotiation. The key material is passed
5858 to the application after the protocol is over.
5860 * Implemented the processing of incoming Key Agreement packet
5861 in the client. Added function silc_client_key_agreement to
5864 * Implemented the intiator side of the key agreement routines
5865 in the client. The client can now initiate key agreement with
5866 another remote client. The key material is passed to the
5867 application after the protocol is over.
5869 * Created client_keyagr.c to include all the key agreement
5872 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5873 SILC_TASK_CALLBACK except that it is not static.
5875 * Created client_notify.c and moved the Notify packet handling
5876 from the client.[ch] into that file.
5878 * Created client_prvmsg.c and moved all private message and
5879 private message key routines from the client.[ch] into that file.
5881 * Create client_channel.c and moved all channel message and
5882 channel private key routines from the client.[ch] into that file.
5884 * Changed silc_client_get_client_by_id_resolve to resolve with
5885 WHOIS command instead of IDENTIFY command, in the file
5886 lib/silclient/idlist.c.
5888 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Implemented the SKE's responder side to the Client library.
5892 * When FAILURE is received to the protocol do not trust it
5893 blindly. Register a timeout to wait whether the remote closes
5894 the connection as it should do it, only after that process the
5895 actual failure. This was changed to both client and server.
5897 * Added client_internal.h to include some of the structures
5898 there instead of client.h in lib/silcclient/.
5900 * Added function silc_task_unregister_by_callback to unregister
5901 timeouts by the callback function.
5903 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Some "Incomplete WHOIS info" errors has been appearing on the
5906 log files. Took away the entry->userinfo check from WHOIS
5907 reply sending. The entry->userinfo is now " " if client did not
5908 provide one. I thought this was fixed earlier but something
5909 is wrong still. Let's see if the error still appears.
5911 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Fixed a minor bug in the login when the channel key is
5914 re-generated in the server. It used to generate the key in
5915 wrong order and thus caused problems in the channel traffic.
5917 * Fixed a minor bug in channel key distsribution after
5918 KICK command. The key was not sent to the router even though
5921 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Added silc_ske_process_key_material_data as generic routine
5924 to process any key material as the SILC protocol dictates. The
5925 function is used by the actual SKE library but can be used by
5926 applications as well. This relates to the private message keys
5927 and the channel private keys since they must be processed the
5928 same way the normal SILC session keys. The protocol dictates
5929 this. Affected files: lib/silcske/silcske.[ch].
5931 Added also silc_ske_free_key_material to free the
5932 SilcSKEKeyMaterial structure.
5934 * Defined silc_cipher_set_key function to set the key for
5935 cipher without using the object's method function. The affected
5936 files: lib/silccrypt/silccipher.[ch].
5938 * Implemented silc silc_client_add_private_message_key,
5939 silc_client_add_private_message_key_ske,
5940 silc_client_del_private_message_key,
5941 silc_client_list_private_message_keys and
5942 silc_client_free_private_message_keys functions in the
5945 Added functions silc_client_send_private_message_key to send
5946 the Private Message Key payload and silc_client_private_message_key
5947 to handle incoming Private Message Key payload.
5949 * Added Cipher field to the Private Message Key payload to set
5950 the cipher to be used. If ignored, the default cipher defined
5951 in the SILC protocol (aes-256-cbc) is used.
5953 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Removed lib/silcclient/ops.h file.
5957 Redefined parts of the SILC Client Library API. Created new
5958 file silcapi.h that deprecates the ops.h file and defines the
5959 published Client Library API. Defined also private message key
5960 API and channel private key API into the file.
5962 This is the file that the application must include from the
5963 SILC Client Library. Other files need not be included by
5964 the application anymore.
5966 * Added new key_agreement client operation callback and also
5967 defined the Key Agreement library API for the application.
5969 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5972 is used by clients to request key negotiation between another
5973 client in the SILC network. If the negotiation is started it
5974 is performed using the SKE protocol. The result of the
5975 negotiation, the secret key material, can be used for example
5976 as private message key.
5978 Implemented the Key Agreement payload into the files
5979 lib/silccore/silauth.[ch].
5981 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Redefined ciphers for the SILC protocol. Added some new ciphers
5984 and defined the key lengths for the algorithms. Changed the
5985 code accordingly. The default key length is now 256 bits.
5987 * Fixed SKE key distribution function silc_ske_process_key_material
5988 when the key length is more than 128 bits. The default key
5989 length in SILC is now 256 bits.
5991 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5992 to indicate unsupported algorithm.
5994 * Renamed rijndael.c to aes.c and all functions as well.
5996 * Fixed a long standing channel key setting bug in client library.
5997 Weird that it has never surfaced before.
5999 * Fixed bug in channel deletion. If the entire channel is removed
6000 then it must also delete the references of the channel entry
6001 from the client's channel list as the client's channel entry and
6002 the channel's client entry share same memory.
6004 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Implemented CONNECT and SHUTDOWN commands in the client.
6008 * Implemented CLOSE command to the client.
6010 * Added the function silc_idlist_find_server_by_name into the
6011 files silcd/idlist.[ch].
6013 Added the function silc_idlist_find_server_by_conn into the
6014 files silcd/idlist.[ch].
6016 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * DIE command was renamed to SHUTDOWN. Updated the both code
6021 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6022 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6024 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6027 * Added function silc_server_create_connection function to create
6028 connection to remote router. My server implementation actually
6029 does not allow router to connect to normal server (it expects
6030 that normal server always initiates the connection to the router)
6031 so the CONNECT command is only good for connecting to another
6034 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6037 or some other client was kicked from the channel.
6039 Implemented the handling of the notify type to both client
6042 Implemented silc_server_send_notify_kicked to send the KICKED
6043 notify. It is used to send it to the server's primary router.
6045 * Implemented the KICK command into server and client.
6047 * Added `query' argument to the silc_idlist_get_client function
6048 to indicate whether to query the client from server or not if
6051 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6052 to indicate that the client is not channel founder.
6056 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Removed the rng context from SilcPacketContext structure and
6059 changed that the packet routine uses the Global RNG API.
6061 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Added support for quit message that client can "leave" on the
6064 channel when it quits the SILC. It is ditributed inside the
6065 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6067 Added silc_server_free_client_data that will take the
6068 signoff message as argument.
6070 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6072 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Updated parts of the protocol specification to keep it up
6077 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6080 payloads in one packet.
6082 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6083 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6084 use now the new List flag.
6086 * Also deprecated the following packet types: REPLACE_ID,
6087 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6089 * Added list support for Notify packet in server.
6091 * Added silc_server_send_notify_channel_change to send the
6092 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6093 the silc_server_send_replace_id.
6095 * Added silc_server_send_notify_nick_change to send the
6096 NICK_CHANGE notify type. Deprecates the function
6097 silc_server_send_replace_id.
6099 * Added silc_server_send_notify_join to send the JOIN notify type.
6100 Deprecates the function silc_server_send_new_channel_user.
6102 * Added silc_server_send_notify_leave to send LEAVE notify type.
6103 Deprecates the function silc_server_send_remove_channel_user.
6105 * Added silc_server_send_notify_cmode and
6106 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6107 types. Deprecates the silc_server_send_set_mode function.
6109 * Added SERVER_SIGNOFF notify type to indicate that server has
6110 quit. This means that all clients on the channel from that
6111 server will drop. This can be also used when netsplit happens.
6113 Deprecated REMOVE_ID packet type since it is not needed anymore
6116 Added silc_server_send_notify_server_signoff to send the
6117 SERVER_SIGNOFF notify type. Deprecates the function
6118 silc_server_send_remove_id.
6120 Added also silc_server_send_notify_signoff to send the
6121 SIGNOFF notify type.
6123 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6124 SILC protocol from this day on. Changed the protocol
6125 specification as well.
6127 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6128 notify type. It is used between routers to notify about
6129 topic changes on a channel.
6131 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6134 * Partly updated the protocol specification to comply with the
6135 changes now made. It is still though a bit outdated.
6137 * The JOIN notify type now takes one extra argument <Channel ID>.
6138 The packet used to be destined to the channel but now the
6139 JOIN type may be sent as list thus it is impossible to
6140 destine it to any specific channel. By adding this argument
6141 it is again possible.
6143 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Added CREDITS file. The CHANGES and CREDITS file will appear
6146 in the distribution as well.
6148 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6151 types in the server's silcd/packet_receive.c.
6153 * Implemented CMODE and CUMODE to work in router environment.
6155 * Fixed minor encoding and decoding buglet from the
6156 lib/silccore/silcmode.c.
6158 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6161 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6163 * Changed all SilcConfigServer* and silc_config_server* to
6164 SilcServerConfig* and silc_server_config*, respectively.
6167 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Associated the ID (client or server ID) to the Authentication
6170 Payload to avoid any possibility of forging. Updated the
6171 protocol specification and the code accordingly.
6173 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * The RSA key length is now save to the RsaKey context in the
6176 key generation process in lib/silccrypt/rsa.c. The key length
6177 is now used to figure out the maximum size of the block allowed
6178 to be encrypted/signed.
6180 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6181 is equivalent to the silc_mp_mp2bin but does not allocate any
6184 * Changed silc_mp_mp2bin API to take length argument. If it is
6185 non-zero then the buffer is allocated that large. If zero, then
6186 the size is approximated using silc_mp_sizeinbase, which however
6189 * Created Global RNG API which is global RNG that application can
6190 initialize. After initializing, any routine anywhere in the
6191 code (including library) can use RNG without allocating a new
6192 RNG object. This was done to allow this sort of use of the
6193 RNG in code that has no chance to allocate RNG object. All
6194 applications currently allocate this and many routines in the
6195 library use this. Affected file lib/silccrypt/silcrng.[ch].
6197 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6198 it to use the Global RNG API.
6200 * Defined Authentication Payload into protocol specification that
6201 is used during SILC session to authenticate entities. It is
6202 used for example by client to authenticate itself to the server
6203 to obtain server operator privileges.
6205 Implemented this payload into the lib/silccore/silcauth.[ch].
6206 Implemented also routines for public key based authentication
6207 as the new protocol specification dictates.
6209 Moved definitions of different authentication methods from
6210 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6212 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6213 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6214 silc_pkcs_verify_with_hash functions into the file
6215 lib/silccrypt/silcpkcs.[ch].
6217 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * The client entry's userinfo pointer must be always valid.
6220 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6221 will fail since it requires the userinfo. Now, the userinfo
6222 is allocated as "" if actual userinfo does not exist. Actually,
6223 it must exist and it is totally Ok to drop client connections
6224 that does not announce the userinfo. However, we will make
6225 this workaround for now.
6227 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6228 to return the remote port by socket.
6230 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6233 SILC_SERVER_PENDING_EXEC and added an new macro
6234 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6235 data or when error occurs while processing the pending command.
6237 Added new argument `destructor' into silc_server_command_pending
6238 and to the SilcServerCommandPending object. This destructor is
6239 now called after calling the pending callback or if error occurs
6240 immediately. If error occurs the actual pending callback won't
6241 be called at all - only the destructor. The destructor may be
6242 NULL if destructor is not needed.
6244 All this applies for client library code as well. Similar
6245 changes were made there as well for the pending commands.
6247 In the client, the application must now allocate the
6248 SilcClientCommandContext with the silc_client_command_alloc
6251 * Added reference counter to the SilcServerCommandContext. Added
6252 function silc_server_command_alloc and silc_server_command_dup
6255 Same type of functions added to the client library for the same
6258 * Removed the cmd_ident from IDListData away since it is now
6259 global for all connections. It is the command identifier used
6260 in command sending and with pending commands. The affected file
6263 * Added reference counter to the SilcSocketConnection objecet to
6264 indicate the usage count of the object. The object won't be
6265 freed untill the reference counter hits zero. Currently only
6266 server uses this, and client ignores it. The client must be
6267 set to use this too later. The affected files are
6268 lib/silccore/silcsockconn.[ch]. Added also the function
6269 silc_socket_dup to increase the reference counter.
6271 This was mainly added because it is possible that the socket
6272 is removed underneath of pending command or other async
6273 operation. Now it won't be free'd and proper DISCONNECTING
6274 flags, etc. can be set to avoid sending data to connection that
6275 is not valid anymore.
6277 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6278 the connection. After that it sets SILC_SET_DISCONNECTED.
6279 It is, however, possible that the socket data is not still freed.
6280 The silc_server_packet_process now checks that data is not
6281 read or written to connection that is DISCONNECTED. The socket
6282 get's freed when the reference counter hits zero.
6284 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Changed the client operation API: channel_message operation's
6287 `sender' is now the client entry of the sender, not the nickname
6288 and the `channel' is the channel entry, not the channel name.
6290 In the private_message operation the `sender' is now also the
6291 client entry of the sender not the nickname.
6293 Affected file is lib/silcclient/ops.h and all applications
6294 using the client operations.
6296 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Moved the calling of ops->connect() from connect_to_server_final
6299 into receive_new_id functin since that is the point when the
6300 client is actually allowed to send traffic to network. The
6301 affected file is lib/silcclient/client.c.
6303 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6306 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6307 (if needs broadcasting) instead of broadcasting the packets one
6308 by one which would make a burst in the network traffic.
6310 * Added `broadcast' argument to the functions in silcd/server.[ch]
6311 silc_server_create_new_channel[_with_id] to indicate whether
6312 to send New Channel packet to primary router.
6314 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Added new function into the silcd/server.[ch] files:
6317 silc_server_create_new_channel_with_id to create new channel with
6318 already existing Channel ID.
6320 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6321 lib/silccore/silcpacket.h. This packet is used t send list of
6322 Set Mode payloads inside one packet. Server uses this to set
6323 the modes for the channels and clients on those channels, that it
6324 announced to the router when it connected to it. The protocol
6325 specification has been updated accordingly.
6327 * The silc_server_new_channel did not handle the packet coming
6328 from normal server as it normally does not send that. However,
6329 when it announces its channels it does send it. Implemented
6330 the support for that.
6332 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6333 into the file lib/silccore/id.h.
6335 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Fixed memory leaks in the functions silc_idlist_del_client,
6338 silc_idlist_del_channel and silc_idlist_del_server in the file
6339 silcd/idlist.c. All of those leaked like a sieve.
6341 * Fixed some small memory leaks in the client's function
6342 silc_client_notify_by_server.
6344 * Added functions into silcd/server.c: silc_server_announce_clients,
6345 silc_server_announce_channels and silc_server_announce_server.
6346 These functions are used by normal and router server to announce
6347 to its primary router about clients, channels and servers (when
6348 router) that we own. This is done after we've connected to the
6351 These functions effectively implements the following packet types:
6352 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6353 and SILC_PACKET_NEW_ID_LIST.
6355 * Added new functions into the silcd/packet_receive.[ch]:
6356 silc_server_new_id_list, silc_server_new_channel_list and
6357 silc_server_new_channel_user_list to handle the incoming
6358 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6360 * Added support of changing Channel ID in the function
6361 silc_server_replace_id. If the server that announces a channel
6362 to the router already exists in the router (with same name but
6363 with different Channel ID), router is responsible to send
6364 Replace ID packet to the server and force the server to change
6365 the Channel ID to the one router has.
6367 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6368 client that the Channel ID has been changed by the router. The
6369 normal server sends this to the client. Client must start using
6370 the new Channel ID as the channel's ID.
6372 Implemented handling of this new type into lib/silcclient/client.c
6373 into the function silc_client_notify_by_server.
6375 * Added new function silc_idlist_replace_channel_id into the files
6376 silcd/idlist.[ch] to replace the Channel ID.
6378 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Call silc_server_command_identify_check always when processing
6381 the IDENTIFY command in silcd/command.c
6383 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6386 send keepalive packets. The packet can be sent by clients,
6387 servers and routers.
6389 Added function silc_socket_set_heartbeat into the file
6390 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6391 If not set, the heartbeat is not performed. The actual
6392 heartbeat is implemented in the low level socket connection
6393 library. However, application is responsible of actually
6396 Added silc_server_send_heartbeat to send the actual heartbeat
6397 packet into silcd/packet_send.[ch]. Server now performs
6398 keepalive with all connections.
6400 * Added silc_task_get_first function into lib/silcutil/silctask.c
6401 to return the timeout task with shortest timeout. There was a bug
6402 in task unregistration that caused problems. TODO has been
6403 updated to include that task system must be rewritten.
6405 * The client library will now resolve the client information when
6406 receiving JOIN notify from server for client that we know but
6407 have incomplete information.
6409 * Rewrote parts of silc_server_remove_from_channels and
6410 silc_server_remove_from_one_channel as they did not remove the
6411 channel in some circumstances even though they should've.
6413 * Encryption problem encountered in server:
6415 The LEAVE command used to send the Channel Key packet to the
6416 router immediately after generating it. However, the code
6417 had earlier sent Remove Channel user packet but not immediately,
6418 ie. it was put to queue. The order of packets in the router
6419 was that Channel Key packet was first and Remove Channel User
6420 packet was second, even though they were encrypted in the
6421 reverse order. For this reason, MAC check failed. Now, this
6422 is fixed by not sending the Channel Key packet immediately but
6423 putting it to queue. However, this is more fundamental problem:
6424 packets that are in queue should actually not be encrypted
6425 because packets that are sent immediately gets encrypted
6426 actually with wrong IV (and thus MAC check fails). So, packets
6427 that are in queue should be encrypted when they are sent to
6428 the wire and not when they put to the queue.
6430 However, the problem is that the current system has not been
6431 designed to work that way. Instead, the packet is encrypted
6432 as soon as possible and left to the queue. The queue is then
6433 just purged into wire. There won't be any fixes for this
6434 any time soon. So, the current semantic for packet sending
6437 o If you send packet to remote host and do not force the send
6438 (the packet will be in queue) then all subsequent packets to the
6439 same remote host must also be put to the queue. Only after the
6440 queue has been purged is it safe again to force the packet
6443 o If you send all packets immediately then it safe to send
6444 any of subsequent packets through the queue, however, after
6445 the first packet is put to queue then any subsequent packets
6446 must also be put to the queue.
6448 Follow these rules and everything works fine.
6450 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added new function silc_server_remove_clients_by_server to
6453 remove all client entries from ID list when the server connection
6454 is lost. In this case it is also important to invalidate all
6455 client entires as they hold the invalid server entry. This
6456 fixes fatal bug when server has lost connection and will reconnect
6459 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Made some sanity checks to silc_server_daemonise like to check
6462 whether the requested user and group actually exists.
6464 * Added sanity check to SKE's silc_ske_responder_finish to check
6465 that the public and private key actually is valid.
6467 * Invalidate the client's nickname when receiving Replace ID
6468 packet and the Client ID is being replaced. This means that the
6469 server will query the nickname if someone needs it (client)
6472 * Sort the ID Cache in client library when the ID Cache data
6473 has changed (needs sorting).
6475 * Do not allow for SILC client to create several connections to
6476 several servers. The client does not support windows right now
6477 and generating multiple connections causes weird behaviour.
6479 Irssi-silc client does support windows and can handle several
6480 connections without problems, see: www.irssi.org and SILC plugin.
6482 * Fixed some places where client was added to the IDList. The
6483 rule of thumb is following (in order to get everything right):
6484 If the client is directly connected local client then the
6485 `connection' argument must be set and `router' argument must be
6486 NULL to silc_idlist_add_client function. If the client is not
6487 directly connected client then the `router' argument must
6488 bet set and the `connection' argument must be NULL to the
6489 silc_idlist_add_client function.
6491 * The funtion silc_server_packet_send_local_channel actually did
6492 not check whether the client was locally connected or not. It
6493 does that now. Fixed a bug related to LEAVE command.
6495 * Fixed Remove Channel User payload parsing bug in server's
6496 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6498 * The server's silc_server_save_channel_key now checks also the
6499 global ID list for the channel as it might not be in the local
6500 list. Fixed a bug related to LEAVE command.
6502 * Is this the end of the [<unknown>] buglet that has been lurking
6503 around for a long time? A little for loop fix in server's
6504 silc_server_command_whois_parse that is used by both IDENTIFY
6505 and WHOIS command. At least, this was a clear bug and a cause
6506 of one type of [<unknown>] buglet.
6508 * WHOIS and IDENTIFY commands call the function
6509 silc_server_command_[whois/identify]_check function even if
6510 we are not router server.
6512 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Added --with-gmp configuration option. If set the GMP
6515 is always compiled in the SILC source tree. If not set then
6516 it is checked whether the system has the GMP3 installed. If
6517 it has then the GMP won't be compiled (the system's headers
6518 and library is used), if it doesn't have it then the GMP is
6519 compiled in the SILC source tree.
6521 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * Changed RSA private exponent generation to what PKCS #1
6524 suggests. We try to find the smallest possible d by doing
6525 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6526 not security fix but optimization.
6528 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Added new config entry [Identity] to fork the server and run
6531 it as specific user and group. A patch from Bostik.
6533 * Imported Dotconf configuration library into lib/dotconf.
6534 This will be used to create the SILC configuration files later.
6535 It will appear in the distsribution after this commit.
6537 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * A big code auditing weekend happening. Auditing code for
6540 obvious mistakes, bugs and errors. Also, removing any code
6543 Removed files for being obsolete:
6545 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6546 inline in the file lib/silcutil/silcbuffer.h)
6548 o lib/silcutil/silcbufutil.c (the header has inline versions)
6550 Changed code to fix possible error conditions:
6552 o The buffer formatting routines now check that the destination
6553 buffer really has enough space to add the data. This applies for
6554 both buffer formatting and unformatting
6555 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6556 unformatting was changed to accomodate following rules:
6557 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6558 sent to the function while XXX_*STRING will not allocate or copy
6559 the data into the buffer. Instead it sets the pointer from the
6560 buffer into the pointer sent as argument (XXX_*STRING used to
6561 require that the pointer must be allocated already). This change
6562 makes this whole thing a bit more consistent and more optimized
6563 (note that the data returned in the unformatting with XXX_*STRING
6564 must not be freed now). The routines return now -1 on error.
6566 o Tried to find all code that use buffer_format and buffer_unformat
6567 and added return value checking to prevent formatting and
6568 especially unformatting errors and possible subsequent fatal
6571 o Changed ske->x and ske->KEY to mallocated pointers in
6572 lib/silcske/silcske.h. Fixed possible data and memory leak.
6574 o Added return value checking to all *_parse* functions. Fixed
6575 many memory leaks as well.
6577 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6578 so that buffer overflows would not happen. All code now also
6579 checks the return value as it can fail.
6581 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Added reconnection support to server if the normal server looses
6584 its connection to the router (for example if router is rebooted).
6585 The server performs normal reconnection strategy implemented
6586 to the server. Affected file silcd/server.c.
6588 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Added new packet type SILC_PACKET_SET_MODE that is used to
6591 distribute the information about changed modes (for clients,
6592 channels and clients channel modes) to all routers in the
6593 network. Updated the protocol specification accordingly.
6595 Added functions into silcd/packet_send.c and
6596 silcd/packet_receive.c: silc_server_send_set_mode,
6597 silc_server_set_mode.
6599 Added new files silcmode.[ch] into lib/silccore that implements
6600 the encoding and decoding of Set Mode Payload. Added new type
6601 SilcSetModePayload. Moved the definitions of different modes
6602 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6604 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Oops, a little mistake in server's connection authentication
6607 protocol. The protocol is not ended with FAILURE but with
6608 SUCCESS if the authentication is Ok. :) Affected file is
6611 * Implemented NICK_CHANGE notify handling in server in the file
6612 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6613 the local clients on the channel. After the changing nickname
6614 in router environment snhould work and the [<unknown>] nickname
6615 should appear no more.
6617 The silc_server_replace_id function that receives the Replace ID
6618 payload now sends the NICK_CHANGE notify type also in the file
6619 silcd/packet_receive.c
6621 * Changed WHOIS and IDENTIFY command to support the maximum amount
6622 of arguments defined in protocol specs (3328 arguments). This
6623 fixed a bug that caused problems when there were more than three
6626 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added extra parameter, command identifier, to the
6629 silc_client_send_command so that explicit command identifier
6632 Changed that ID list routines uses specific command identifier
6633 when sending WHOIS/IDENTIFY requests to the server so that they
6634 can be identified when the reply comes back.
6636 Affected files lib/silcclient/command.[ch],
6637 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6639 * Added `sender' argument to silc_server_packet_send_to_channel
6640 to indicaet the sender who originally sent the packet to us
6641 that we are now re-sending. Ignored if NULL. Affected file
6642 silcd/packet_send.[ch].
6644 * Added some server statistics support in silcd/server_internal.h
6645 SilcServerStatistics structure and around the server code. Also
6646 send some nice statistics information when client is connecting
6649 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Fixed channel ID decoding in server's JOIN command reply in
6652 silcd/command_reply.c
6654 * Fixed braodcasting of replace ID payload to not to send it if
6655 we are standalone server in silcd/packet_receive.c.
6657 * Fixed all channel message sending routines to not to send
6658 packets to clients that has router set, since they are routed
6659 separately in the same function earlier. Affects file
6660 silcd/packet_send.c and all channel packet sending functions.
6662 * In USERS reply, res_argv[i] are not allocated, the table
6663 is allocated. Thus changed that free the table, not its
6666 * In server's whois_check and identify_check if the client is
6667 locally connected do not send any WHOIS commands - they are not
6670 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * Fixed some minor bugs in client when sending WHOIS command. The
6673 arguments was in wrong order.
6675 * Removed statis function add_to_channel from server in
6676 silcd/command.c that was previously used with the joining but
6679 * Tested USERS command in router environment successfully with two
6680 routers, two servers and two clients.
6682 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Reorganized the USERS command and command reply in client library
6685 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6686 When the command is given by user we register a pending command
6687 callback that will reprocess the command after the reply has been
6688 received from the server. When reprocessing the packet we then
6689 display the information. Thus, the USERS information is displayed
6690 now in the command callback instead of in the command reply
6691 callback. The processing of the command is same as previously
6692 when server has sent the command reply in the JOINing process.
6694 * Added to USERS command in silcd/command_reply.c to join the client,
6695 we didn't use to know about, to the channel after we've created
6696 a client entry for it. Also, for clienet we did know already still
6697 check whether it is on the channel or not and add it if not.
6699 * Removed silc_server_command_join_notify as the function and its
6702 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Changed the client's pending command handling to the same as the
6705 server's pending command handling. It is also now possible to
6706 execute command reply functions from other command reply
6707 function as the function callbacks for commands and command
6708 replies are one and same. The pending commands are not static
6709 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6710 in client connection context. Thus, pending commands are server
6711 connection specific as it is convenient.
6713 Changed the function silc_client_command_pending and
6714 silc_client_command_pending_del and added new function
6715 silc_client_command_pending_check. Removed the
6716 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6719 * Added cmd_ident, current command identifier, to the client
6720 connection context in lib/silcclient/client.h to keep track on
6721 command identifiers used in command sending. Client's command reply
6722 function handling now supports the mandatory command identifiers.
6724 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6725 funtions in client to fully support pending command callbacks.
6727 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6728 as one of the arguments to the application in the command reply
6731 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6732 before first releasing SILC but came back. Now it is removed again
6733 and should come back nomore. The FORWARDED flag was used only
6734 by the JOINing procedure by forwarding the command packet to router.
6735 Now, the JOINing procedure has been changed to more generic (due
6736 to various router environment issues) and FORWARDED is not needed
6737 anymore for anything. The protocol specification is yet to be
6740 Now, removed silc_server_packet_forward from server and the flag
6741 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6743 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Renamed NAMES command to USERS command. The NAMES was named that
6746 due to historical reasons. Now it is renamed. Also, rewrote
6747 parts of the USERS command. The nickname list is not sent anymore
6748 by the server. Only Client ID and mode lists are sent in the USERS
6749 command. Changed this also to the protocol specification.
6751 The client now resolves the names and stuff after it receives
6752 the USERS list from the server when joining to the channel.
6754 * WHOIS and IDENTIFY commands has been changed to support multiple
6755 Client ID's per command. One can now search for multiple users
6756 in the network by sending only one WHOIS or IDENTIFY command.
6757 Changed the code and the protocol specifications.
6759 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6760 uses silc_server_command_whois_parse to parse the request. */
6762 * If normal server, do not parse the WHOIS and IDENTIFY requests
6763 before sending it to the router. Saves some time.
6765 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6767 * Fixed JOIN command on client library. Wrong number of arguments
6768 used to crash the client.
6770 * Added silc_server_channel_has_global function to check whether
6771 channel has global users or not.
6773 * Added silc_server_channel_has_local function to check whether channel
6774 has locally connected clients on the channel.
6776 * The silc_server_remove_from_one_channel now checks whether the
6777 channel has global users or not after given client was removed from
6778 the channel. It also checks whether the channel has local clients
6779 on the channel anymore. If it does not have then the channel entry
6780 is removed as it is not needed anymore.
6782 * The silc_server_notify now checks on JOIN notify whether the joining
6783 client is one of locally connected or global. If it is global then
6784 the channel has now global users on the channel and that is marked
6785 to the channel entry. Also, it now saves the global client to
6786 global list who is joining and JOINs it to the channel. This is
6787 for normal server, that is.
6789 Changed silc_server_send_notify_on_channel,
6790 silc_server_packet_relay_to_channel and
6791 silc_server_packet_send_to_channel check if we are normal server
6792 and client has router set (ie. global client) do not send the
6793 message to that client, as it is already routed to our router.
6795 * Implemented LEAVE notify type handling in silc_server_notify
6798 * Tested LEAVE command in router environment successfully. Tested
6799 with two routers, two servers and two clients.
6803 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6805 * Implemented SIGNOFF notify type handling in silc_server_notify
6808 * silc_server_remove_id now removes the client entry from all channels
6809 it has joined and thusly sends SIGNOFF notify type.
6811 * Rewrote the NAMES list generation in server by removing two excess
6812 loops. The lists are created now inside one loop.
6814 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6816 * silc_server_remove_channel_user checks now also global list
6817 for channel and client.
6819 * silc_server_new_channel_user checks now both local and global
6820 list for channel and client. Fixed a bug in client id decoding.
6821 Used to decode wrong buffer.
6823 * silc_server_channel_message checks now both local and global
6824 list for channel entry.
6826 * Tested channel joining (hence JOIN) in router environment
6827 successfully. Tested with two routers, two servers and two
6830 * Tested channel message sending in router environment successfully.
6832 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Added silc_server_save_channel_key into server.[ch] to save the
6835 received channel key in Channel Key payload processing. It is
6836 also used in JOIN command reply handling.
6838 Equivalent function silc_client_save_channel_key added into
6839 client.[ch] into client library.
6841 * Changed JOIN command reply to send information whether the channel
6842 was created or not (is existing already) and the channel key
6843 payload. Changed protocol specs accordingly.
6845 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6846 the request was sent by ID and not by nickname. Crashed on
6849 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6851 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6852 now correctly save the received data.
6854 * silc_server_free_sock_user_data now notifies routers in the
6855 network about entities leaving the network.
6857 At the same time implemented functions silc_server_remove_id
6858 and silc_server_send_remove_id to receive and send REMOVE_ID
6859 packets. The packet is used to notify routers in the network
6860 about leaving entities. The ID removed will become invalid in
6863 * Added function silc_idlist_del_server into server. Removes and
6864 free's server entry from ID list.
6866 * silc_server_private_message function now checks, if we are router,
6867 that the destination ID really is valid ID, naturally.
6869 * In router when NEW_ID packet is received (for new client) the
6870 hash of the Client ID is saved in the ID Cache but the
6871 client->nickname is set to NULL, instead of putting the hash
6874 IDENTIFY command now also checks that client->nickname must be
6875 valid. If it is not if will request the data from the server who
6876 owns the client. Added new function
6877 silc_server_command_identify_check.
6879 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6880 to set the command to already allocated Command Payload.
6882 * Tested private message sending in router environment with two
6883 routers, two servers and two clients. Fixed minor bugs and now
6886 * Fixed segfault from client's NAMES command. Used to crash if
6889 * Forwarded packets must not be routed even if it is not destined
6890 to the receiver. Changed server code comply with this.
6892 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Added `require_reverse_mapping' boolean value to ServerParams
6895 structure. If TRUE (not default) the server will require that
6896 the connecting host has fully qualified domain name.
6898 If the reverse mapping is not required and hostname could not be
6899 found the IP address is used as hostname.
6901 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Implemented version string checking to both client and server.
6904 The check is incomplete currently due to the abnormal version
6905 strings used in development version of SILC.
6907 * Changed all command functions in server to use the new
6910 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * Changed char *data to unsigned char *data in ID Cache system to
6913 support binary data as ID Cache data. Changed code to support
6914 binary data in lib/silccore/idcache.c.
6916 * Renamed silc_server_packet_relay_command_reply to
6917 silc_server_command_reply as it is normal packet receiving
6918 function. Rewrote the function to accept command replys for
6919 servers and not only for clients.
6921 * Mark remote router always as registered server if we are connecting
6922 to it. Otherwise, commands sent by the router to us are ignored.
6924 * All ID List find routines now returns the ID Cache Entry pointer
6925 as well if requested.
6927 * WHOIS command works now in router environment, tested with two
6928 routers, two servers and two clients.
6930 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6931 in router environment (as it is almost equivalent to WHOIS) but
6932 hasn't been tested thoroughly. Added new functions:
6934 silc_server_command_identify_parse
6935 silc_server_command_identify_send_reply
6936 silc_server_command_identify_from_client
6937 silc_server_command_identify_from_server
6939 * Disabled route cache adding because adding two different ID's with
6940 same IP replaces the old cache entry thus giving wrong route.
6941 The entry->router->connection is always the fastest route anyway
6942 so route cache may not be needed. Of course, new routes maybe
6943 established after receiving the ID when the entry->router->connection
6944 might not be anymore the most optimal.
6946 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Add route cache for received ID for fast routing.
6950 * Added silc_server_packet_route to route received packet on router
6951 that is not destined to us.
6953 * Renamed silc_server_get_route to silc_server_route_get.
6955 * Added id_string and id_string_len fields into SilcServer to
6956 include encoded ServerID for fast comparing without excess
6957 encoding of the ID's.
6959 * Cleaned up WHOIS command on server side. Added following static
6962 silc_server_command_whois_parse
6963 silc_server_command_whois_check
6964 silc_server_command_whois_send_reply
6965 silc_server_command_whois_from_client
6966 silc_server_command_whois_from_server
6968 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6969 arguments in command replies. All command functions should be
6970 updated to use this macro.
6972 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Minor typo fixes on command reply handling on server.
6976 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Added silc_server_command_add_to_channel internal routine to add
6979 the client to the channel after router has created the channel and
6980 sent command reply to the server.
6982 * Added generic silc_server_send_command to send any command from
6985 * Use static buffer with ID rendering instead of duplicating data.
6987 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6989 * Fixed a channel user mode bug when joining to a channel server gave
6990 everybody channel founder rights, oops.
6992 * We mark ourselves as the router of the incoming server connection
6993 if we are router ourselves. This way we can check in some packet
6994 sending functions whether it is locally connected server. For
6995 incoming router connections we put NULL.
6997 * For router sending packets locally means now always sending the
6998 packet cell wide; to local clients and local servers. For normal
6999 server sending packet locally means sending it to only local
7002 * Fixed the JOIN command to really work in router environment. If the
7003 channel is created it is always created by the router. Router is
7004 also responsible of making the initial joining to the channel,
7005 sending JOIN notify to the sending server and distributing
7006 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7007 does not exist server doesn't do anything else but forward the
7008 command to the router which performs everything.
7010 * Added silc_server_send_channel_key function to send the Channel Key
7013 * Added silc_server_create_channel_key to create new channel key. The
7014 channel key is now re-generated everytime someone joins or leaves
7015 a channel, as protocol dictates. Note: channel->key_len is the
7018 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7021 packet_receive.[ch] to separate packet sending and receiving
7022 routines. The server.[ch] now includes everything else including
7023 actual packet processing (writing and reading data) and other
7026 Renamed silc_server_private_message_send_internal to
7027 silc_server_send_private_message. The routine is still though
7028 used only to relay private messages as server does not send
7029 private messages itself.
7031 Renamed silc_server_new_channel to silc_server_create_new_channel
7032 and added new function sicl_server_new_channel that handles the
7033 incoming New Channel packet. Added also new sending function
7034 silc_server_send_new_channel to send New Channel Payload.
7036 * Added new function silc_server_notify to process incoming notify
7037 packet to the server/router. Server may then relay the notify
7038 to clients if needed.
7040 * Added new function silc_server_new_channel_user to process incoming
7041 New Channel User packet. Router will redistribute the packet and
7042 send JOIN notify to its local clients and locally connected servers
7043 if needed. Normal server will send JOIN notify to its local client
7044 on same channel when received this packet. Added also corresponding
7045 sending function silc_server_send_new_channel_user to sent the
7048 * Added boolean route argument to send_notif_to_channel and
7049 packet_send_to_channel functions to attempt to route the packet
7050 if it is TRUE and send only locally if it is FALSE.
7052 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7054 * silc_server_replace_id now broadcasts the received replace ID
7055 packet if it is not broadcast packet already. The router must
7056 broadcast to inform other routers about changed ID.
7058 * Added backpointer to server's router into SilcServer context in
7059 silcd/server_internal.h.
7061 * Fixed silc_server_packet_broadcast to send correct broadcast
7064 * The channel key is now distributed to the local client as soon
7065 as it is received from the router (in router environment) so that
7066 no other packet may be sent for the channel until client has
7069 * silc_server_remove_channel_user now broadcasts the received
7070 Remove Channel User packet if it is not broadcast packet already.
7071 The router must broadcast to inform other routers about removed
7074 * Added users field into SilcPacketContext that is a reference count
7075 of the context. One can increase the reference count by calling
7076 silc_packet_context_dup which is now changed to just increase the
7077 reference count instead of duplicating the data. The reference
7078 count is decresed by calling silc_packet_context_free that will
7079 free the data after the reference count hits zero.
7081 For now on the packet context and everything allocated into it
7082 (including the raw packet from network) must be freed by calling
7083 the new silc_packet_context_free function. Added also new function
7084 silc_packet_context_alloc that must be used now to allocate the
7085 context. This also means that if a routine is asynchronous from
7086 silc_[client/server]_packet_parse_type the packet context must
7087 be duplicated by calling silc_packet_context_dup. Otherwise it
7088 gets free'd after silc_[client/server]_packet_parse_type returns.
7089 Also, one must remember that if packet is duplicated then its
7090 reference count must be decresed by calling the free function as
7091 many times as it was duplicated.
7093 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7094 from both client and server.
7096 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Made joining to a channel working in router environment.
7100 * Cleaned up JOIN command on server side and create function
7101 silc_server_command_join_channel internal routine to make the
7104 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Changed silc_command_pending list to SilcDList. Also, added
7107 `ident' field to SilcServerCommandPending structure to identify
7108 the reply and to call correct callback.
7110 Added silc_server_command_pending_check function to replace the
7111 corresnponding macro. The silc_command_pending list is not
7114 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7115 to set identifier to previously allocated Command Payload. It
7116 is used to set identifier for command when resending Command
7119 * Added silc_command_payload_encode_payload to encode Command
7120 Payload buffer from SilcCommandPayload structure.
7122 * Added silc_argument_payload_encode_payload to encode Argument
7123 payload buffer from SilcArgumentPayload structure.
7125 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Changed WHOIS command to support router connection on server side.
7128 The whois request is always sent to router unless the server is
7129 standalone server. After server has received the reply from the
7130 router will it send the reply to the client.
7132 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7133 broadcast received broadcast packet. The function is used only
7134 by router. The broadcast packet is always sent to the router's
7137 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7138 render given ID to printable string, for log files for example.
7140 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Made basic router to router connections working. At least they
7143 can now connect to each other but nothing really works the way
7144 they are supposed - yet.
7146 * Added new initiator token to RouterConnection configuration
7147 file in silcd/serverconfig.[ch]. It is used to tell whether we
7148 are the initiator to the remote router or whether we'll expect
7149 the other end to connect.
7151 * Moved registering of listener task to silc_server_init, hence
7152 the server starts listenning as soon as it is run, even if it
7153 does not have connections to other routers. Let's see how well
7156 * Changed default connection retry timeouts for more suitable in
7159 * Removed cipher and such arguments from silc_idlist_add_client
7160 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7161 Added new function silc_idlist_add_data to add the keys and stuff
7164 * Added SilcIDListData structure and added it to SilcClientEntry
7165 and SilcServerEntry as their first field in the structure. This
7166 way we can explicitly cast the ID entries to the SilcIDListData
7167 structure and get common data for the entries. In past, we had
7168 to first check what type of connection it is and then cast it to
7169 correct ID entry type. Now, we can directly cast the opaque
7170 pointer to the SilcIDListData (no matter what ID entry it actually
7171 is) and get the data needed.
7173 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7175 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7176 in some circumstances even if threre were timeout tasks, though not
7177 IO tasks, but tasks anyway. Now fixed.
7179 * Defined SilcServerConnection structure to hold connection specific
7180 stuff about directly connected servers and routers. The definition
7181 is currently in silcd/server_internal.h. I thought about having
7182 a bit more important role fro this struct but for now it is used
7183 only when connecting to other server (or router actually).
7185 * Added connecting retry support in server when connecting to
7186 router(s). The retry feature implement exponential backoff
7187 algorithm. Also, added SilcServerParams structure to hold default
7188 parameters for server. For now, it include these retry settings
7189 and are hard coded. After server is moded to be as Silc Server
7190 Library this structure will be more important.
7192 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Changed client librarys channel->clients table to SilcList and
7195 changed code accordingly.
7197 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Changed client's channel table to SilcList and changed code
7200 accordingly. Also changed SilcChannelClientEntry to include back-
7201 pointer to the channel so that client entry can use that structure
7202 as list as well and we have fast cross-reference to the channel.
7203 This change dramatically decreased the complexity of channel
7204 handling with client entry and vice versa (removed one extra
7205 loop when searching for channel entry from many functions).
7207 * Changed server->sim from table to SilcDList and changed code
7210 * NAMES command can now be used from user interface. It will show
7211 the user list on the channel, neatly.
7213 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7214 Code now saves realname of the user if it becomes available.
7216 * Renamed configure.in to configure.in.pre and made ./prepare
7217 script to automatically add correct version string to
7218 configure.in which it creates from configure.in.pre.
7220 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * NAMES command reply now shows users mode with the nickname when
7225 * Moved silc_client_ch[u]mode[_char] functions from
7226 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7227 place sucks, they are utility functions and should be in some
7230 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7232 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7235 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Added TRQ (efficient deque and list library) into lib/trq. This is
7240 a very good list library that is currently used in the SILC. Defined
7241 SilcList API over the library because I didn't like the API very
7242 much. See lib/trq/silclist.h for the API and examples of how to
7243 use the API. Fixed various places in the code to use the new
7244 SilcList API. The SilcList is meant for lists that has a structure
7245 already defined as a list. It is not suitable to add just some
7246 context to the list (in TRQ, the context is the list actually).
7248 So, I defined SilcDList that can be used for the purpose where
7249 predefined list structure does not exit. This can be used as
7250 such list. Now some context just can be added to the SilcDList.
7251 Currently this list is not used in the SILC just yet, though there
7252 are a lot places where this can replace dynamically allocated
7253 tables and I will fix these places, later, to use SilcDList.
7254 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7255 and use TRQ internally).
7257 Also fixed some annoying warning messages that the original TRQ
7258 code generated. Also minor changes to TRQ's Makefile.in.
7260 * Added support for querying by Client ID to both WHOIS and
7261 IDENTIFY commands into server, as required by the protocol.
7263 * Removed method function pointers from SilcBuffer structure. They
7264 weren't used to anything and just increased the context size for
7265 no good reason. This change also made silc_buffer_alloc and
7266 silc_buffer_free functions inline functions.
7268 * Disabled command flooding detection support until it's fixed so
7269 that it accepts commands in but does not execute them more than once
7272 * Added silc_net_localhost(), to return local hostname, into
7273 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7274 that must be initialized before calling silc_client_init.
7276 * Added new function: silc_server_send_notify_on_channels to send
7277 notify messages to all channels client has joined. It is assured
7278 that the message is sent only once per client.
7280 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7281 lib/silcutil/silcutil.[ch] as silc_format function. The new
7282 function is generic and is used by server as well, not only by
7283 the logging routines.
7285 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7286 the provided version string was not acceptable. Added new function:
7287 silc_ske_check_version into lib/silcske/silcske.h. The function
7288 must be implemented by the application (client or server) and it
7289 does not reside in the SKE library. The function checks the version
7290 string remote end sent.
7292 * Added back pointers (to opaque context and to SilcSocketConnection)
7293 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7295 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7296 duplicate packet context structure.
7298 * Changed `notify' client operation to send same arguments as client
7299 receives from server except for ID's. ID's are mapped to correct
7300 ID entry and that is returned. Also, if channel entry is not sent
7301 by server but the notify is for channel the channel entry is sent
7302 to application (otherwise application doesn't know that it is for
7303 channel (library gets it from packet's Destination ID)).
7305 * Added silc_client_remove_from_channels into client library to
7306 remove a client from all channels it has joined to. Used when
7307 received SIGNOFF notify from server. Added also new function
7308 silc_client_replace_from_channels to replace old ID entry with
7309 new ID entry on all channels. Used when received NICK_CHANGE
7312 * Fixed ID Cache list handling in silc_idlist_get_client in
7313 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7314 to get (or query) client by ID.
7316 * Updated TODO list.
7318 * Added connection authentication status message defined by the
7319 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7320 support for these into the code in client and server side.
7322 * Added generic function silc_client_send_command to send any command
7323 with variable argument list. Application should use this function
7324 to send commands if the command functions provided by the library
7325 does not suite for the application's user interface needs.
7327 * Added new `failure' client operation. Application is notified about
7328 received failure packet if client is executing a protocol. In this
7329 case the protocol's execution has failed.
7331 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7332 is required by the protocol.
7334 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7335 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7338 * Added status flag to SilcSKE object to indicate realtime status
7339 of the SKE protocol.
7341 * Application receives now exactly same command reply arguments as
7342 the library receives from server. However, if ID is received the
7343 corresponding ID entry is returned to the application (eg. Client
7344 ID is mapped to correct SilcClientEntry entry and that is returned).
7345 Changed command_reply client operation due to this change.
7347 * Changed all ID's in commands and in command replys as ID Payloads.
7348 Change affected both client and server side codes.
7350 All ID's sent in SILC network (with execption of ID's in SILC
7351 Packet header) are sent in ID Payload to support variable length
7354 * Server now notifies nick changes and notifies all clients on
7355 the channels about the new nickname (about the new Client ID,
7358 * Implemented CMODE command to change channel modes. Supports all
7359 channel modes defined by the protocol specs except ban and invite
7360 lists. (Also, private channel key mode is supported but support for
7361 setting private channel key in client is missing, thus, this mode
7362 has no effect on client side (except that server requires that the
7363 client uses private channel key and normal channel traffic does not
7366 Also, invite mode works per se, but INVITE command does not work
7367 yet correctly, so you can set channel as invite only channel but
7368 inviting clients to the channel does not work (it is yet to be
7369 thought what's the best way to do it).
7371 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7372 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7373 Implemented CUMODE command to change user's mode on the channel.
7374 Supports all modes defined by the protocol specs.
7376 * Added NAMES command reply to return users modes on the channel.
7378 * Removed unnecessary and slow ciphers from lib/silccrypt.
7380 * Set SO_KEEPALIVE option to connection sockets by default.
7382 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7384 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7385 redefined the Notify Payload into protocol specs.
7387 * Added silc_id_payload_parse_id to get ID directly from raw
7390 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7393 accept searching by Client ID as well.
7395 * Added support for LEAVE and SIGNOFF notify types in client library.
7397 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7398 to parse ID Payload from raw data.
7400 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Added flags parameter into silc_ske_assemble_security_properties
7403 function in lib/silcske/silcske.[ch].
7405 * Changed notify client operation to fit better for notify messages
7406 sent by server. The notify payload received from server is now
7407 passed to the application (after parsing it to SilcNotifyPayload).
7408 It is application's responsibility to retrieve the arguments
7409 from the payload and show the message the way it wants. The message
7410 sent by server is implementation specific.
7412 * Changed public keys to comply with the protocol specification.
7413 Old public keys are not supported anymore and are not compatible.
7415 * Removed nickname from Channel Payload as the latest draft removed
7416 it. The client must resolve the nickname from the NAMES command
7417 reply received when it joined the channel.
7419 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7421 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7423 * Fixed some errors in protocol specification drafts.
7425 * Created lib/silccore/silcnotify.c to implement Notify Payload
7426 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7427 generic payloads described by protocol specifications. The file
7428 includes implementations for ID Payload and Argument Payload.
7430 * Changed Command Payload implementation to use the new Argument
7431 Payload. Changed command_xxxx_payload to command_payload_xxxx
7432 to comply with SILC coding conventions.
7434 * Added suppport for Argument Payload handling in Notify Payload
7435 implementation as protocol requires it. Added the new support
7436 into server and client lib as well.
7438 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7440 * Added support for multiple nicknames on same channel. [n] is
7441 added locally to the nickname if there are more than one same
7442 nicknames on the channel.
7444 * Server now sends all nicknames that matched WHOIS request.
7445 Client also shows the list received from server.
7447 * Added TOPIC command to client side. User can now set and show
7448 current topic on channel.
7450 * Added MOTD command to client and server. Also, server sends the
7451 motd when client connects to the server.
7453 * Changed version strings to comply ISO 8601.
7455 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Fixed protocol error handling in client library. It should now
7458 cope even if the SKE fails for some reason.
7460 * Made new protocol specification drafts for submitting to IETF.
7462 * Implemented TOPIC command to server in silcd/command.c.
7464 * Added two new notify types into lib/silccore/silcnotify.h:
7465 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7466 notify nickname change and topic setting/change on a channel.
7468 * API change of command_reply operation in client library. The
7469 application gets now the status type received from server as well.
7471 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7475 * Cras fixed and optimized the packet handling even further and
7476 it should work now. Minor change to the prototype of function
7477 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7479 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Added new function into lib/silcutil/silcschedule.[ch]:
7482 silc_schedule_with_fd to select() a specified fd. The function
7483 returns after timeout expires or data arrives or goes. The
7484 function is used by packet routines to wait that all data is
7485 received from network.
7487 * Fixed data reading from network in lib/silccore/silcpacket.c.
7488 The code now assures that all data is read from the fd and then
7489 continues packet processing. This was a bug fix since the code
7490 used to drop some data in some circumstances.
7492 * Added new function into lib/silcclient/client.[ch]:
7493 silc_client_start_key_exchange to start key exchange after
7494 connection has been established to server. The code internally
7495 now uses this funtion but its main purpose was to provide it
7496 for applications that perform their own connecting. After
7497 application has created a connection it merely calls this
7498 function to start the key exchange between client and server.
7499 The library takes care of everything else after that.
7501 Updated also lib/silcclient/README to explain the usage of
7504 * Do not send to application information that connection has
7505 been established. Application gets notified it by connect
7508 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Applied cras's patch to add silc_schedule_one function. The
7511 function runs scheduler once and returns.
7513 * Fixed the scheduler after cras messed it up. The timeout
7514 handling works now as it's supposed to work.
7516 * Added into lib/silccore/ silcnotify.h to include notify
7517 message types support. Changed silc_server_send_notify*
7518 functions, in server.[ch], to support those new notify types.
7519 Added the support for the notify types into client library,
7520 as well. Added new notify client operation into ops.h in
7523 * Changed silc_server_packet_send_to_channel to send normal
7524 packets instead of just channel message packets. The function
7525 is now used to send the notify packets to channels. It is not
7526 used to send channel message packets anymore, as server never
7529 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7530 va_arg()s as it seems to require it nowadays. I guess, if SILC
7531 is compiled with older va_arg() the new code should work anyway.
7533 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7535 * Splitted core library. Core library (lib/silccore) includes
7536 now only SILC protocol specific core (and common) components.
7537 Created new utility library (lib/silcutil) that includes more
7538 generic purpose stuff. The stuff for util library was taken
7539 from the old core library. This was minor and easy split.
7541 * Created SILC Client Library (lib/silcclient) that includes
7542 implementation of the SILC client without user interface. This
7543 was major move from silc/ directory. The code has been changed
7544 so that it is transparent towards the user interface. The
7545 silc/ directory includes now the same user interface as before
7546 and it uses the new client library. Read lib/silcclient/README.
7547 Basicly, the client library performs everything else related
7548 to SILC except user interface handling. Also, configuration
7549 files are considered to be part of user interface and library
7550 does not handle them.
7552 This change also changed a lot of structures, function naming etc.
7553 Most important change was that SilcClientWindow object was
7554 renamed to SilcClientConnection in the client library. Created
7555 also new file lib/silcclient/ops.h. Also added new files
7556 silc/local_command.[ch] and silc/client_ops.[ch].
7558 All these changes were made to make it easier for user interface
7559 designers to create what ever user interface for the SILC client
7562 It is also expected that the server will be moved to lib
7563 directory as well and SILC Server Library will be created;
7564 sometimes in the future.
7566 * Removed Local commands from lib/silccore/silccommand.h as
7567 they are application specific and new client library does not
7568 handle any of those anymore.
7570 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7571 old client implementation in silc/.
7573 * Added support for callback functions in SILC_LOG_* macros.
7574 Application can now set its own callbacks that will be called
7575 instead of using the default functions that will always print
7576 the debug messages to stderr (or stdout). Also, debugging can
7577 now be disabled by setting silc_debug to FALSE and re-enabled by
7578 setting it to TRUE. Note, that logging will still work even
7579 if debugging is disabled.
7581 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7582 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7583 silc_log_reset_debug_callbacks.
7585 * To enable debugging in silc client one must give now -d
7586 option on command line.
7588 * Changed silc_schedule_init to automatically allocate task queues
7589 if they are not allocated before calling it.
7591 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Added GMP 3.1 into math library.
7595 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7598 a channel in SILC network. The packet is used by servers and
7599 routers to notify other routers that user has left a channel.
7600 This little feature was missing until now. Added the feature
7601 to protocol specification as well.
7603 Added functions: silc_server_send_remove_channel_user and
7604 silc_server_remove_channel_user into server.[ch].
7606 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7607 lib/silccore/silcpacket.h. However, they are not implemented
7610 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Fixed joining to a channel and sending channel messages
7613 between server and router. The channel message sending should
7614 now work inside a cell.
7616 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * Fixed the private message sending between server and router.
7619 The private message sending should now work inside a cell.
7621 * Added silc_server_replace_id into server.[ch] to replace
7622 existing ID in the SILC network.
7624 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7625 and silc_idlist_replace_server_id into idlist.[ch] in server.
7627 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7629 * Fixed the server to server connections. Server can again now
7630 connect to router. Router to router connections probably does
7633 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7635 * Added dynamic protocol registering support. Now protocols can
7636 registered and unregistered on the fly. Patch by cras.
7638 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Added lib/contrib directory to hold routines that some platforms
7641 don't have but are needed by SILC.
7643 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7644 into lin/contrib to provide getopt() and getopt_long() for
7645 those who don't have it.
7647 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7649 * Added AWAY command to client. When away message is set and
7650 client receives a private message packet the client automatically
7651 replies to the sender with the away message.
7653 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7654 bug seemed to be the cause of recent problems when compiling
7657 * Added version detection support to SKE protocol specification
7658 and added the new changes to the SKE implementation as well.
7659 There were other minor changes in the SKE protocol as well.
7661 Many changes in lib/silcske/silcske.[ch] and in
7662 lib/silcske/payload.[ch].
7664 * Added ^U functionality, clear input line. Patch from cras.
7666 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7668 * Mainly small bugfixes on core library. Fixed some debugging
7669 logging and buffer overflow in silclog.c.
7671 * Updated config.sub and config.guess on the distribution tree.
7673 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7675 * Added command lagging support in server. Client may execute
7676 commands now only once in two seconds.
7678 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7680 * Optimized packet reception. MAC computation and checking is now
7681 also more optimized. A lot previously duplicated code is now
7682 used as generic by both client and server.
7684 * Fixed key pair generation in clientutil.c
7686 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7688 * Added into lib/silccore/silcbufutil.[ch] new function;
7689 silc_buffer_realloc.
7691 * Moved generic packet sending/encryption functions to
7692 lib/silccore/silcpacket.[ch] from client and server. Some
7693 rewriting of the functions.
7695 * Moved all generic packet reception/decryption functions to
7696 lib/silccore/silcpacket.[ch] from client and server. The
7697 packet processing is now much cleaner in both client and server.
7698 These were major changes in both client and server.
7700 * Created many common functions in server to do packet sending.
7701 Previously code were duplicated a lot, this has been removed
7704 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7706 * Rewrote major parts of the ID cache system. Don't know
7707 whether it is better now or not but at least the API is more
7710 * Major rewrite on ID cache stuff on client because of the ID
7711 cache API changes. Added idlist.c to client.
7713 * Also major rewrite on ID cache stuff on server as well.
7714 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7715 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7716 in hand, instead they are all put into the ID cache system now.
7717 All server_idlist_* routines uses ID cache now instead of
7718 traversing its own lists (those lists does not exist anymore).
7719 SilcIDList though still exists. Also, SilcXXXEntry's are
7722 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7724 * Finally made the SKE implementation compliant to the protocol
7725 specification. All mp integers are now binary encoded as
7726 opposed being HEX encoded.
7728 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7731 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7732 functions: silc_[encode/decode]_pem. Also added function
7733 silc_encode_pem_file to PEM encode with newlines ('\n') for
7736 * SILC public keys are now encoded either PEM or binary. Same
7737 option is for private keys as well. By default private keys
7738 are binary encoded and public keys PEM encoded. Silly HEX
7739 encoding were removed.
7741 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7742 function to create fingerprints.
7744 * Fixed a bug in SHA1; does not change the original data anymore.
7746 * Partly implemented INFO command on client and server side.
7747 Fixed CLEAR command. Changes to SERVER command; show current
7748 server(s) when giving command without arguments. Added
7749 VERSION command to client.
7751 * Added check to server that unregistered connections cannot
7752 execute commands (unless it is specificly allowed).
7754 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Fixed screen refresh.
7758 * Fixed channel joining bug from client. On some circumstances
7759 client tried to join to a channel it had already joined.
7761 * Added public key verification process into client's protocol.c.
7762 The client now verifies the public key from user and saves
7763 it into ~./silc/serverkeys/ directory.
7765 Added into: clientutil.[ch]: silc_client_verify_server_key.
7767 * Changed SKE protocol's silc_ske_initiator_finish function
7768 to accept callback function that verifies the received public
7769 key. Removed old silc_ske_verify_public_key function.
7771 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7773 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7774 silc_pkcs_private_key[_data]_set.
7776 * Made the password and public authentication more cleaner in
7777 server's protocol.c.
7779 * Removed historic and obsolete protocol `channel_auth' from
7780 both client and server.
7782 * Removed wrong way of sending command status messages from
7783 server to client in server's command.c. The old way violated
7784 protocol specification.
7786 Changes to silccore/silccommand.[ch]: removed
7787 silc_command_encode_status_payload -> not needed anymore,
7788 changed silc_command_encode_payload_va to accept extra
7789 argument on variable argument list. The argument type must
7790 now be provided to the function. Also, added new function:
7791 silc_command_encode_reply_payload_va which is same as
7792 normal command_encode_payload_va except command status type
7793 is provided as extra argument.
7795 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7797 * Added ~./silc directory handling. The directory includes the
7798 public and private keys for the client.
7800 Added silc_client_check_silc_dir, silc_client_create_identifier
7801 and silc_client_load_keys.
7803 * Implemented SILC protocol compliant public key. Added public
7804 and private key saving to and loading from files.
7806 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7807 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7808 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7809 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7810 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7812 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7813 silc_pkcs_load_[public/private]_key.
7815 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7817 * Added silc_server_get_route (route.[ch]) to get connection
7818 data for the fastest route for given ID.
7820 * Implemented INVITE command on client and server. The command
7821 were re-defined in the SILC Protocol Specification and the
7822 implementation now complies with the specification.
7824 * Implemented PING command on client and server.
7826 * Implemented NAMES command on client and server. The server side
7827 supports currently only normal server not router server yet.
7828 Some changes to NAMES definition in SILC protocol specification.
7830 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7832 * Implemented LEAVE command on client and server.
7834 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7835 again. This change was made to the protocol as well. Server
7836 should not violate the protocol specification anymore.
7838 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7841 was tested. SOCKS4 was not but should work anyway.
