1 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the object argument for silc_cipher_register,
4 silc_hash_register, silc_hmac_register and silc_pkcs_register
5 to const. Affected files are lib/silccrypt/silccipher.[ch],
6 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
8 * Changed the silc_get_username and silc_get_real_name to
9 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
11 * Fixed the Irssi SILC Client to use the silc_get_username and
12 silc_get_real_name insted of glib routines since the glib
13 routines only corrupt stack. Fixes the Irssi SILC to work in
14 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
16 * Fixed the Irssi to not use g_get_home_dir since it crashes
17 or returns garbage on cygwin and corrupts stack. Added function
18 get_home_dir to Irssi routines. Affected files are
19 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
21 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
23 * Made some structure optimizations. SFTP memory FS MemFSEntry
24 entry structure. Optimized SilcTask structure. Optimized
25 SilcPacketContext structure.
27 Affected files lib/silcsftp/sftp_fs_memory.c,
28 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
30 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
32 * And yet again reverted back the config thing since Johnny
33 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
36 * Fixed memory leaks from config object. Affected files are
37 silcd/serverconfig.[ch].
39 * Added support for adding new connections to the server in rehash.
40 After rehash they take effect.
42 Added support for changing the maximum allowed connections in
43 rehash. The number can grow but going smaller is not supported.
45 Added function silc_server_num_sockets_by_remote to the
46 silcd/server_util.[ch].
48 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
50 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
52 * Added preliminary checking during config parsing for a valid
53 public/private key and removed further checks in the code.
54 Affected files are silcd/serverconfig.[ch], server.c.
56 * Moved functions silc_server_drop() and silc_server_daemonise()
57 from server.c to silcd.c since they are stricly related to
58 the application activity.
60 * Reverted a small part of the automatic ref/unref since
61 it caused a double unref in some situations. Affected
62 files are silcd/silcd.[ch], server.c, serverconfig.c.
64 * Added some .cvsignore files in the lib directory.
66 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
68 * Fixed silc_net_gethostbyaddr to correctly resolve by
69 address. Affected file lib/silcutil/silcnet.c.
71 * Fixed the notify relaying to client. The HMAC to be used
72 with relayed packets ws wrong and caused decryption failure
73 at the client end. Affected file is silcd/packet_receive.c.
75 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
77 * Created new branch silc_protocol_1_0_branch.
79 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
81 * Changed the silc_server_config_* routines to be SilcServer
82 independent. They are now officially application specific code
83 and not part of generic server implementation. Affected files
84 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
86 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
88 * Added automatic referencing of config context in the
89 silc_server_config_alloc, and automatic unreferencing in the
90 silc_server_config_destroy. Affected files are
91 silcd/serverconfig.[ch], silcd/silcd.c.
93 * Fixed the silc_log_quick handling in the logging routines.
94 It didn't log quickly when it was TRUE. Affected file is
95 lib/silcutil/silclog.c. Also the flush delay was set even
96 if it was 0 in config file. Affected file is
99 * Added support for changing key pair of the server in rehash.
100 Affected file silcd/server.c.
102 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
104 * Fixed the TOPIC_SET notify to not cras. It changed the topic
105 too early, before getting the channel entry. Affected file
106 is silcd/packet_receive.c.
108 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
110 * Added functions silc_server_config_[ref/unref], these are used
111 to prevent that the config object is destroyed.
113 No longer directly affect global variables silc_log_quick and
114 silc_log_delay, they are first cached inside the config object
115 and then applied with silc_server_config_setlogfiles().
117 silc_server_config_set_defaults() is now internal to
118 serverconfig.c, there are no reasons to show this internal stuff
121 Affected files are silcd/serverconfig.[ch].
123 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
124 fprintf's to stderr, since some code may be executed again after
125 the server went into the background. Affected files are
128 * Added rehash support. Added function silc_server_rehash() that
129 will perform all the basic tasks of the rehashing procedure.
131 * Added command line option `-x, --hexdump'. This will enable the
132 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
133 The option `--hexdump' implies `--debug'.
135 * Fixed a bad bug in the logging APIs (silcutil library) where
136 the application would crash after calling silc_log_reset_all().
138 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
140 * Fixed the KICKED notify handling in client library to
141 correctly remove the channel and all entries from the
142 channel when I was kicked. This bug crashed the client.
144 Fixed yet another but in KICKED notify handling to remove
145 the kicked client correctly from the channel.
147 Affected file is lib/silcclient/client_notify.c.
149 * Fixed a minor bug in looking up correct client entry
150 in KICKED notify in server. Affected file is
151 silcd/packet_receive.c.
153 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
154 sources correctly to distribution. Fixes --with-gmp option.
156 * Removed the manual rehashing from ID Cache, and changed it
157 to use the SILC Hash Table's auto rehash feature. Affected
158 file is lib/silccore/silcidcache.c.
160 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
162 * Fixed a bug in the silc_client_nickname_format function that
163 handles the multiple same nickname formatting. Two clients
164 with same nickname caused problems after the first one left
165 and rejoined. It didn't format the nickname correctly.
166 Affected file is lib/silcclient/idlist.c.
168 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
170 * Don't change the topic if olod topic is same as new one.
171 Affected file is silcd/packet_receive.c.
173 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Added cross-reference support to the SILC Documentation
176 generator. All types across all HTML files are now cross-
177 referenced. Affected files util/robodoc/generator.c and
178 scripts/silcdoc/silcdoc.
180 * Added file lib/silcutil/silctypes.h to include all the
181 arithmetic type definitions and some macros. Removed
182 includes/bitmove.h and moved macros to silctypes.h.
184 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
186 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
188 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
190 * Added `type' argument to silc_id_payload_parse_id function which
191 now returns the type of the ID to the sent pointer. Affected
192 file is lib/silccore/silcid.[ch].
194 * Added check for CMODE_CHANGE notify type that mode change is
195 allowed by the sender. Affected file silcd/packet_receive.c.
197 * Added check for CUMODE_CHANGE notify type that mode change is
198 allowed by the sender. Affected file silcd/packet_receive.c.
199 Added the ID type as CUMODE_CHANGE notify type as argument
200 to the `notify' client operation. Affected files are
201 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
203 * Added function silc_client_add_server to the client library.
204 Added support for resolving also channel and server info when
205 received unknown entity in notify packet. Affected files are
206 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
208 * Added function silc_command_get_status to return the command
209 status from the command reply's argument payload. Affected files
210 are lib/silccore/silccommand.[ch].
212 * Added check for KICKED notify type that the kicking is
213 allowed by the client. Affected file silcd/packet_receive.c.
215 * Created function silc_get_input which can be used to get input
216 (echo on or off) from user on command line. Affected files are
217 lib/silcutil/silcutil.[ch].
219 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
221 * Optimized silc_server_packet_relay_to_channel function.
222 Added new function silc_channel_message_payload_encrypt which
223 can be called directly if channel message payload needs to
224 be encrypted and is already encoded (no need to call _encode
225 function). Packet relaying is now done by router without any
226 extra memory allocations. Affected files are
227 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
230 * Fixed the INVITE notify handling. It took wrong arguments
231 as invite list and invite delete. Affected file is
232 silcd/packet_receive.c.
234 * Added check for TOPIC_SET notify type that the topic change is
235 allowed by the client. Affected file silcd/packet_receive.c.
237 * Added check for INVITE notify type that inviting is allowed by
238 the client. Affected file silcd/packet_receive.c.
240 * Changed the silc_server_client_on_channel to return the
241 SilcChannelClientEntry as well. Moved the function
242 silc_server_check_cmode_rights to server_util.[ch].
243 Affected files are silcd/server_util.[ch], silcd/command.c.
245 * Added function silc_server_check_umode_rights to check whether
246 changing client's user mode is allowed. Added check for
247 UMODE_CHANGE notify type that the umode change is allowed
248 by the client. Affected files are silcd/server_util.[ch],
249 silcd/packet_receive.c and silcd/command.c.
251 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
253 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
254 ID length. It ignored that ID can be IPv6 based as well.
255 Affected file lib/silccore/silcpacket.h.
257 * Fixed the silc_id_id2str and silc_id_str2id to take the
258 IPv6 address offset's into consideration. Affecte file is
259 lib/silccore/silcid.c.
261 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Fixed the internal Unix scheduler functions to check for
264 NULL context they may receive. The affected file is
265 lib/silcutil/unix/silcunixschedule.c.
267 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
269 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
270 can specify different directory with --home command line
271 parameter. Affected files irssi/src/silc/core/client_ops.c,
274 * SILC-specific commands aren't now executed if the active server
275 isn't of SILC-type, so there won't be problems with having
276 IRC and SILC protocol support in same client. Affected files
277 irssi/src/silc/core/silc-channels.c, silc-servers.c,
280 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
282 * Improved the signal support in SILC Schedule. Added new
283 function silc_schedule_signal_call which is used by application
284 to mark a signal to be called. It is now safe to perform
285 any kind of tasks in signal callbacks since it is guaranteed
286 that the application specified signal callback is called
287 after the signal is over. Affected files are
288 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
290 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
292 * Added `name' field to SilcChannelPrivateKey to represent
293 application given name for the key. Moved also the context from
294 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
295 Added the `name' argument also to the function
296 silc_client_add_channel_private_key.
298 Added function silc_client_current_channel_private_key to set the
299 current channel private key in use.
301 Added "change" command to KEY command which can be used to change
302 the current channel private key. Bound the command also to
305 Also affected files lib/silcclient/client_channel.c,
306 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
308 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
310 * Added silc_rng_get_byte_fast function in to the
311 lib/silccrypt/silcrng.[ch].
313 * Changed the interface of silc_packet_assemble and the
314 silc_packet_send_prepare. If silc_packet_assmble is now
315 called the application does not call silc_packet_send_prepare
316 because the library will call it automatically. These
317 interfaces now also return a reference to the outgoing buffer
318 which includes the assembled packet, which the application can
319 use to encrypt the packet.
321 Affected files are lib/silccore/silcpacket.[ch],
322 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
323 silcd/packet_send.c, server_backup.c and packet_receive.c.
325 * Fixed a packet sending bug on very high load, where outgoing
326 packet queue wasn't handled correctly and packets got corrupted.
327 Affected files are lib/silcutil/*/silc*sockconn.c,
328 lib/silcclient/client.c and silcd/server.c.
330 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
332 * Added macro SILC_PACKET_DATALEN which can be used during
333 packet assembling to check whether the data to be added to
334 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
335 len is truncated until it fits it.
337 Added checks for maximum length of channel message payload and
338 private message payload also.
340 Added checks for maximum packet length in server and in
343 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
344 lib/silcclient/client.c, lib/silccore/silcchannel.c and
345 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
346 lib/silcclient/client_prvmsg.c.
348 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
350 * Added silc_server_packet_queue_purge call to the
351 silc_server_disconnect_remote to assure that all data in the
352 queue before disconnecting is sent to the network. Affected
355 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
357 * Added the deleting of server's own ID cache entry to the
358 silc_server_free function. Free also everything else that
359 has been allocated in silc_server_init. The affected file
362 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
364 * Added functions silc_parse_version_string, silc_version_to_num,
365 and silc_ske_parse_version to parse SILC protocol style version
366 strings. Affected files lib/silcutil/silcutil.[ch] and
367 lib/silcske/silcske.[ch].
369 * Added new configuration params: version_protocol, version_software
370 and version_software_vendor to specify what version the remote
371 host must at least be to be able to connect to server. The vendor
372 string can be regex matched too. Added new function
373 silc_server_connection_allowed to check maximum number of allowed
374 connections, and allowed versions for incoming connections.
375 Affected files are silcd/server.c, server_util.[ch] and
378 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
380 * Added preliminary support for signals in scheduler. The
381 signals we care about are now blocked always when the scheduler
382 is locked. This way we can synchronise the use of signal with
383 scheduler. It is guaranteed that when signal occurs the scheduler
384 is not locked, and thus new tasks can be safely added to the
387 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
388 to silc_schedule_internal_init and silc_schedule_internal_uninit.
389 Added new platform specific routines
390 silc_schedule_internal_signals_[un]block and
391 silc_schedule_internal_signal_[un]register.
393 Added new functions to SILC Schedule API:
394 silc_schedule_signal_[un]register. Each signal that application
395 is going to use should be registered to the scheduler.
397 Affected files are lib/silcutil/silcschedule.[ch],
398 lib/silcutil/*/silc*schedule.c.
400 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
402 * Check for unauthenticated client and server in the
403 silc_server_new_client and silc_server_new_server functions.
404 Affected file silcd/packet_receive.c.
406 * Added function silc_string_is_ascii to check whether given
407 string is 7-bit ASCII string. Affected files are
408 lib/silcutil/silcutil.[ch].
410 * Added function silc_id_is_valid_server_id into the
411 silcd/serverid.c and added checking for valid Server ID's in
412 silc_server_new_server. The Server ID must always be based
413 on the server's public IP address.
415 * Added logging of DISCONNECT packet message in the server.
416 Affected file silcd/server.c.
418 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
420 * Changed all library interfaces that use Global RNG to also
421 accept SilcRng as argument. Affected files are
422 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
423 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
424 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
425 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
428 * Added function silc_pkcs_generate_key to the
429 lib/silccrypt/silcpkcs.[ch] for applications so that they
430 don't need to do pkcs->pkcs->init calls anymore.
432 * Remove SilcSocketConnection from the SFTP API since it really
433 wasn't needed there. The application has the information
434 saved in its contexts anyway and the SFTP layer doesn't need
435 know about it. Affected files lib/silcsft/silcsftp.h and
436 lib/silcsftp/sftp_[server/client].c.
438 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
439 The SilcSimContext is not SilcSim.
441 * Fixed possible buffer overflows in silc_id_render in the
442 lib/silcutil/silcutil.c.
444 * On EPOC the global crypto module lists are not used at all
445 in the crypto library. Added support for using the constant
446 algorithm list on EPOC. Affected files are
447 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
450 * Fixed the handling of third parameter of KICKED notify, since
451 it was mistakenly updated to SILC Protocol 1.0 even though it
452 is to be included in 1.1. Since it is not in 1.0 it is not
453 mandatory, and this fix now handles it only if it is provided,
454 and it is not error if it is not provided. Affected file
455 lib/silcclient/client_notify.c.
457 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
459 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
460 client. Affected file irssi/src/silc/core/client_ops.c.
462 * Merged with Irssi 0.8.4 from irssi.org CVS.
464 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
466 * Check for valid socket connection in client entries before
467 sending any messages. Fixes a crash, but doesn't fix some
468 other underlaying bug that is lurking there. Affected
469 file silcd/packet_send.c.
471 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
473 * $usermode, $cumode and $cumode_space expandos shouldn't do
474 anything with non-SILC server records. Affected file
475 irssi/src/silc/core/silc-expandos.c
477 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
479 * Fixed the silc_net_check_[host/local]_by_sock to support
480 IPv6 bound sockets as well. Now they can return IPv6 addresses
481 as well. Affected file lib/silcutil/silcnet.c.
483 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
484 Affected lib/silcutil/unix/silcunixnet.c.
486 * Fixed ID rendering (at least on some platforms, not NetBSD)
487 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
489 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
491 * Added silc_hash_public_key and silc_hash_public_key_compare
492 functions to be used with SilcHashTable. They can be used to
493 hash public keys and compare public keys in hash table. Affected
494 file lib/silcutil/silcutil.[ch].
496 * Added support for specifying multiple public keys for Client
497 connection section in server configuration file. This makes it
498 possible to accept multiple public keys from same host, or to
499 make a section that accepts any incoming host, and have the
500 accepted public keys listed in the section.
502 Added functions silc_sever_[find/get]_public_key, added the
503 support for this actually to all connection sections but only
504 the Client section is currently allowed to specify multiple
507 Affected files are silcd/server.c, server_internal.h,
508 command.c, protocol.c, server_util.[ch], packet_receive.c.
510 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
512 * Merged Irssi 0.8.2 from irssi.org CVS.
514 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
516 * If silc_debug is TRUE, also output standard logging messages
517 to stderr with the debug output.
519 Made silc_log_reset_all() flushing all channels before returning.
520 Also fixed some documentation typos.
522 Affected files are lib/silcutil/silclog.[ch].
524 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Fixed the server to check correctly the amount of connections
527 from single host, by checking also the type of the connection.

679 the SKE interface a bit.
681 * Fixed padding problem in PKCS#1. The padding was not actually
682 random since the random number generator was used incorrectly.
683 This security bug affects only when encrypting with PKCS#1, and
684 it is not currently used at all in SILC. SILC only use signing
685 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

766 algorithm parts and created new file silcalgs.conf, that
767 is now included from the example_silcd.conf.in.
769 * Optimized the silc_server_connect_to_router_second to take
770 the connection configuration object from the SilcServerConnection
771 object instead of finding it during the connecting phase.
772 Added the configuration object to SilcServerConnection struct.
773 Affected files silcd/server_internal.h, server.c.

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

857 * Fixed the file transfer's key agreement payload to include
858 zero port also if the hostname is NULL because it could not
861 Call file transfer monitor callback now also if error occurs
862 during key agreement protocol.
864 Changed the silc_client_file_send interface to return the
865 SilcClientFileError instead of session id. The session ID
866 is returned into pointer provided as argument.

883 file lib/silcutil/silclog.c.
885 * Fixed the channel message payload decryption in the function
886 silc_channel_message_payload_decrypt to not modify the original
887 buffer before it is verified that the message decrypted
888 correctly. Otherwise, next time it is called with correct
889 channel key it won't encrypt since the payload is corrupted.
890 Affected file lib/silccore/silcchannel.c.
892 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

906 become invalid in the callback but it was referenced after
907 the callback returned.
909 Do not allow auto rehashing of hash table during the
910 silc_hash_table_foreach operation, for same reasons as it is
911 not allowed for SilcHashTableList. Affected files are
912 lib/silcutil/silchashtable.[ch].

936 lib/silcclient/idlist.[ch].
938 * Fixed a bug in hash table tarversing. While the hash table
939 is traversed with SilcHashTableList the table must not be
940 rehashed. It is now guaranteed that auto rehashable tables
941 are not rehashed while tarversing the list. Also defined that
942 silc_hash_table_rehash must not be called while tarversing
943 the table. Added function silc_hash_table_list_reset that must
944 be called after the tarversing is over. The affected files are
945 lib/silcutil/silchashtable.[ch].
947 * Changed all hash table traversing to call the new
948 silc_hash_table_list_reset in server and in client library.
950 * Added function silc_client_on_channel to return the

967 sender's old command identifier was not saved back to the
968 sender's command context, fixed now. The affected file is
971 * Create the key in JOIN command of the router did not return
972 the channel key, added check for this. Affected file is
975 * Fixed a channel ID update bug in JOIN command reply. Do
976 not directly upgrade the ID but call the function
977 silc_idlist_replace_channel_id if the ID was changed.
978 Affected file silcd/command_reply.c.
980 * Fixed memory leaks from command calling if it would fail.
981 Affected file silcd/command.c.

1008 functions. Affected file silcd/server.c.
1010 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1011 which ID was changed. This way the router will send the
1012 user list for the channel again, and server won't be in
1013 desync in some rare circumstances. Affected file is
1014 silcd/packet_receive.c.
1016 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1075 change founder's mode than the founder itself, there was a
1076 little bug. Affected file silcd/command.c.
1078 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1080 * Removed the SilcClientCommandDestructor from the client
1081 libary, it is not needed anymore. Affected files are
1082 lib/silcclient/silcapi.h, command[_reply].[ch],
1083 client_notify, idlist.c.
1085 * Fixed GETKEY command to first resolve client, and then
1086 resolve the server only if the client was not found, instead
1087 of resolving both at the same time. Affected file is
1088 lib/silcclient/command.c.
1090 * Added silc_client_start_key_exchange_cb and lookup the
1091 remote hostname and IP address before starting the key
1092 exchange with server. The affected file is
1093 lib/silcclient/client.c.
1095 * The server's public key is now saved using the IP address
1096 of the server and not the servername for the filename.
1097 The hostname public key filename is checked as an fall back
1098 method if the IP address based filename is not found.
1100 Fixed the GETKEY command to save the fetched server key
1101 in correct filename.
1103 Print the remote server's hostname now when new key is
1104 received during connection process. Affected file is
1105 irssi/src/silc/core/client_ops.c.
1107 * Return always our own public key to the client if it asks
1108 for it with GETKEY command. Affected file silcd/command.c.
1110 * Removed the use_auto_addr variable from default config
1111 file since it was in wrong section. Affected file is
1114 * Fixed TOPIC_CHANGE notification to not route it when it
1115 was sent using silc_server_send_notify_to_channel function.
1116 Affected file silcd/command.c.
1118 * Fixed silc_server_send_notify_kicked to send the kicker's
1119 Client ID also, it was missing. Affected files are
1120 silcd/command.c, silcd/packet_send.[ch].
1122 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1124 * Do not save client history information in SERVER_SIGNOFF.
1125 Fixes the bug in normal server that it does not detect
1126 the client becoming valid after the server becomes back
1127 online. Affected file silcd/server_util.c.
1129 * Added `sock_error' field into the SilcSocketConnection
1130 context. When error occurs during socket operation (read
1131 or write) the error is saved. Added also new function
1132 silc_socket_get_error to return human readable socket error
1133 message. Affected files are lib/silcutil/silcsockconn.[ch],
1134 lib/silcutil/unix/silcunixsockconn.c, and
1135 lib/silcutil/win32/silcwin32sockconn.c.
1137 * The server now prints the socket error message in the
1138 signoff for client. Affected file silcd/server.c.
1140 * Fixed the `created' channel information sending from router
1141 to server in JOIN command. Checks now whether the channel
1142 really was created or not and set it according that.
1144 Fixed the JOIN command to use the client entry's current
1145 ID during the joining procedure instead of the one it sent
1146 in the command (it is checked though), since it can change
1147 between the packet processing and command processing, and
1148 would just case unnecessary pain in the client end. Affected
1149 file silcd/command.c.
1151 * Fixed a channel key payload sending to use correct channel
1152 ID when the server was forced to change the channel's ID by
1153 router. Router sent the key payload with the old Channel ID.
1154 Affected file silcd/packet_receive.c.
1156 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1158 * Call silc_server_save_channel_key only if the key payload
1159 was provided in the JOIN command's command reply. Affected
1160 file silcd/command_reply.c.
1162 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1164 * Fixed silc_mp_sizeinbase to return the value correctly with
1165 MPI. Affected file lib/silcmath/mp_mpi.c.
1167 * Fixed the stop_server signal to correctly stop the scheduler
1168 and gracefully stop the server when SIGTERM or SIGINT signals
1169 are received. Affected file silcd/silcd.c.
1171 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1173 * Simple handling of TERM and HUP signals. Also added some log
1174 flushing call around. Affected file is
1177 * Fixed small bugs in silclog.c. Now buffering output will take
1178 effect after 10 seconds since startup: This will ensure that
1179 no important startup messages are lost. Also output redirection
1180 will preserve original format ([Date] [Type] message).
1181 Affected file is lib/silcutil/silclog.c.
1183 * Added two options to the config file, in the logging section:
1184 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1185 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1187 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1189 * Do not print the warning about log files not being initialized
1190 more than once to avoid excess logging. Affected file is
1191 lib/silcutil/silclog.c.
1193 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1194 the SIM copying in make install in Makefile.am.pre.
1196 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1198 * Rewritten silclog APIs. Globally interesting changes follows:
1199 silc_log_set_files() changed to silc_log_set_file().
1200 silc_log_set_callbacks() changed to silc_log_set_callback().
1201 ROBOdoc documented silclog header file.
1202 SilcLogCb now returns bool to wether inihibit the default
1203 handler or not (to keep the old behaviour return always TRUE).
1204 The new APIs should also fix the problem of the
1205 silcd_error.log file that was written in the current directory.
1208 Log files streams will remain opened after silc_log_set_file()
1209 call, means less CPU usage notably on high traffic servers.
1210 File streams are now full buffered, and flushed to the disk
1211 every 5 minutes, lesses HD activity and CPU usage.
1212 Messages can be redirected, allowing admins to configure
1213 one single logfile for all server messages.
1214 the silc_log_quick global variable to activate fast-logging.
1215 Affected files lib/silcutil/silclog.[ch]
1217 * Changed some code to conform new silclog APIs. Affected
1218 files are doc/example_silcd.conf.in, silcd/server.c
1219 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1222 * Fixed a memory leak that could occur in some situations.
1223 Affected file silcd/serverconfig.c.
1225 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1227 * Added the silc_client_del_client to remove the client from
1228 all channels as well. Affected file lib/silcclient/idlist.c.
1230 * Fixed the client library to correctly remove the client
1231 from all channels when the client entry is being destroyed.
1232 Affected file lib/silcclient/client_notify.c, command.c.
1234 * Added auto-nicking support to the client library. If the
1235 applicatio now sets client->nickname it will be sent to the
1236 server after connecting by the library. This way for example
1237 SILCNICK (or IRCNICK) environment variables will have effect
1238 and always change the nickname automatically to whatever
1239 it is wanted. Affected file lib/silcclient/client.[ch].
1241 * Renamed silc_server_command_bad_chars to the
1242 silc_server_name_bad_chars and moved it to the
1243 silcd/server_util.[ch]. Added also new function
1244 silc_server_name_modify_bad to return nickname that
1245 includes bad characters as new nickname without those
1246 bad characters. This check and modify is now used in
1247 silc_server_new_client when the username is initially set
1248 as nickname, so it must be checked to be valid nickname.
1249 Affected file silcd/packet_receive.c.
1251 * The nickname length is now taken from the packet for real
1252 and not trusted to strlen() since it clearly can return
1253 wrong length for nickname including bad characters. This
1254 also applies to channel names. Affected file silcd/command.c.
1256 * Removed the lib/silcsilm/modules directory. Modules are now
1257 compiled into the lib/silcsim. Fixed the copying of the
1258 modules to follow symbolic links in Makefile.am.pre.
1260 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1262 * Fixed silc_string_regexify list creation. Fixes bugs with
1263 BAN and INVITE commands in server. The affected file is
1264 lib/silcutil/unix/silcunixutil.c.
1266 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1268 * Removed the command destructor entirely from the server's
1269 command and command reply routines. It is not needed, and
1270 its usage was buggy and caused crashes. Affected files are
1271 silcd/command[_reply].[ch].
1273 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1275 * Cancel protocol and NULL sock->protocol if timeout
1276 occurred during protocol. Affected file silcd/server.c.
1278 * Cancel protocol timeouts always before calling the final
1279 callback, to assure that after final callback is called
1280 no other state will be called for the protocol anymore.
1281 Affected file silcd/protocol.c.
1283 * Print error log if incoming connection configuration could
1284 not be found. Affected file silcd/server.c.
1286 * Fixed JOIN command to correctly save the founder mode
1287 to the client on normal SILC server, when the channel
1288 was created by the router. Affected file silcd/command.c.
1290 * Fixed LIST command (hopefully) to send correct reply
1291 packets. Affected file silcd/command.c.
1293 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * The silc_packet_receive_process now returns FALSE if the
1296 read data was invalid packet, and TRUE if it was ok.
1298 The server now checks that if unauthenticated connection
1299 sends data and its processing fails the server will close
1300 the connection since it could be a malicious flooder.
1302 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1304 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1306 * Make sure the warning about error opening a log file is
1307 printed only once and not everytime it fails (produces
1308 too much useless log). Affected file lib/silcutil/silclog.c.
1310 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1312 * Made the silc_server_daemonise() function more readable.
1313 Affected file silcd/server.c.
1315 * Pid file is now optional, the user may comment it out from
1316 the config file. Removed define SILC_SERVER_PID_FILE, we
1317 don't need a default any longer. Affected file
1318 configure.in.pre, lib/Makefile.am.pre.
1320 * Make some use of the pid file. The server now dies at startup
1321 if it detects a valid pid file on his path. The server would
1322 die anyway in this circumstance, because of the bind() failure.
1323 Affected file silcd/silcd.c.
1325 * No longer compiling lib/dotconf.
1327 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1329 * Fixed JOIN command parsing not to crash. Affected file
1330 lib/silcclient/command.c.
1332 * Fied the NICK_CHANGE notify to add the new client entry
1333 even it is resolved. This removes an <[unknown]> nick
1334 thingy bug in the client. Affected file is
1335 lib/silcclient/client_notify.c.
1337 * Do not try to allocate 0 bytes (efence does not like it)
1338 in lib/silccore/silccomand.c when encoding payload.
1340 * Do not take IRCNICK as nickname in Irssi SILC client since
1341 it is not possible to set nickname before hand connecting
1342 the server (TODO has an entry about adding auto-nicking
1345 * Changed the silc_server_command_pending to check whether
1346 there already exists an pending entry with the specified
1347 command, command identifier and pending callback. This is
1348 to fix IDENTIFY and WHOIS related crashes that may register
1349 multiple pending commands with same identifier. Affected
1350 file silcd/command.c.
1352 * Fixed the server to reconnect to the router even if it
1353 was already reconnecting and EOF was received. This to
1354 fix a possibility that the server wouldn't ever try to
1355 auto-reconnect to the router. Affected file silcd/server.c.
1357 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1359 * Fixed the server's password authentication to use the
1360 length of the locally saved password, and not the one
1361 sent in the packet. Affected file silcd/protocol.c.
1363 * Fixed same password authentication problem in the
1364 Authentication Payload handling routines in
1365 lib/silccore/silcauth.c.
1367 * Yet another password authentication problem fixed with
1368 channel password handling in silcd/command.c.
1370 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * If first character of string in silc_parse_userfqdn is '@'
1373 then do not parse it. Affected file is
1374 lib/silcutil/silcutil.c.
1376 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Fixed minor bug in IDENTIFY command reply sending, which
1379 caused various weird problems during JOIN when it was
1380 resolving names for users. Affected file silcd/command.c.
1382 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Fixed the IDENTIFY command reply sending to chech better valid
1385 clients. It was possible to send incomplete list of replies.
1386 Affected file silcd/command.c.
1388 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Added silc_client_command[s]_[un]register functions now to
1391 dynamically register the commands in client library. Removed
1392 the static table of commands. This allows the client library
1393 to call commands without causing the application to know about
1394 what commands library has called.
1396 Removed the INFO command reply kludge to detect when the command
1397 was called by library. Now library use its own command reply
1398 function for INFO command.
1400 Added function silc_client_command_call to call a command.
1401 Application can use it to call command, not access the structure
1404 Now all commands that are sent by the client library (not
1405 explicitly sent by application) use own command reply functions.
1407 Affected files around lib/silcclient/ and in
1408 irssi/src/silc/core/.
1410 * Fixed the WHOIS command reply sending to chech better valid
1411 clients. It was possible to send incomplete list of replies.
1413 Fixed the WHOIS and IDENTIFY to send the request to router
1414 if normal server did not do it and did not find any results.
1416 Affected file silcd/command.c.
1418 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Moved the internal data from SilcClient context into its
1421 own file, not accesible to application. Affected files
1422 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1423 and other files in client library.
1425 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Added doc/examples installation target in Makefile.am.pre.
1430 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1433 commands the found client entry will be removed from the
1434 cache, after notifying application about the error. Affected
1435 file lib/silcclient/command_reply.c.
1437 * Changed the /MSG to check for exact nickname user gave, and
1438 not let `nick' match `nick@host' if it is only one found. Now,
1439 user must type the exact nickname (like nick@host2) even if
1440 there are no more than one same nicks found. This is to avoid
1441 a possibility of sending nickname to wrong nickname since
1442 `nick' could match `nick@host'. Affected file is
1443 irssi/src/core/silc-servers.c.
1445 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Do not print "you are now server operator" or similar when
1448 giving /away command. Affected files are
1449 irssi/src/silc/core/client_ops.c, silc-servers.h.
1451 * Made the silc_server_command_pending_error_check to send
1452 the same command reply payload it received back to the
1453 original sender of the command. This way all arguments
1454 that was received by the server will be received by the
1455 client too. Affected file silcd/command.c.
1457 * Added the silc_idcache_add to return the created cache entry
1458 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1460 * Add global clients to expire if they are not on any channel.
1461 This is because normal server will never know if they signoff
1462 if they are not on any channel. The cache expiry will take
1463 case of these entries. This is done by normal servers only.
1464 The affected files are silcd/command_reply.c,
1465 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1467 * If server receives invalid ID notification for WHOIS or
1468 IDENTIFY and the ID exists in the lists, it is removed.
1469 Affected file silcd/command_reply.c.
1471 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1472 in client then client entry that it matches is searched and
1473 the nickname is printed on the screen for user. Affected
1474 file irssi/src/silc/core/client_ops.c.
1476 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Use cache entry expire time in the LIST command reply to
1479 purge old entries from the cache after the LIST command
1480 reply has been received. This way we don't have non-existent
1481 entries in the cache for too long. Affected file is
1482 silcd/command_reply.c.
1484 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * If we are normal server, and we've not resolved client info
1487 in WHOIS or IDENTIFY from router, and it is global client,
1488 we'll check whether it is on some channel. If it is not
1489 then we cannot be sure about its validity and will resolve it
1490 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1491 file silcd/command.c.
1493 * Search channel by name (if possible) rather than by ID
1494 in IDENTIFY command's command reply. Affected file is
1495 silcd/command_reply.c.
1497 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1500 Updated specs and implemented it. Affected file silcd/command.c,
1501 silcd/packet_send.c and silcd/packet_receive.c.
1503 * Implemented the <founder auth> payload handling in the JOIN
1504 command. If provided all conditions for channel joining
1505 except requirement to provide correct passphrase can be
1506 overrided by the channel founder. Updated the protocol specs.
1507 Affected file silcd/command.c.
1509 Added support for founder auth in JOIN command in client
1510 library. Fixed the parsing of the JOIN command now to support
1511 all options as they should be. The affected file is
1512 lib/silcclient/command.c.
1514 * Optimized the WHOIS and IDENTIFY commands to send the request
1515 to router only if it includes nicknames or other names. If
1516 they include only IDs then check the local cache first before
1517 routing. Affected file is silcd/command.c.
1519 * Added channels topic announcements. Affected file is
1520 silcd/packet_receive.c and silcd/server.c.
1522 * Fixed the silc_server_send_notify_topic_set to really destine
1523 the packet to channel. Affected file silcd/packet_send.c.
1525 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1526 library. Affected file lib/silcclient/client_notify.c.
1528 * Added UMODE announcements. Affected file silcd/server.c.
1530 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Memory leak fixes in:
1534 lib/silcutil/silcsockconn.c
1535 lib/silcske/silcske.c
1536 lib/silcske/groups.c
1538 lib/silccrypt/silcpkcs.c
1539 lib/silccore/silccommand.c
1540 lib/silccore/silcidcache.c
1545 * ROBOdoc documented the lib/silcske/groups.h file and a
1546 bit changed the interface for better.
1548 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1550 * Update the client entry context in the ID cache after
1551 nick change. Affected file lib/silcclient/command.c.
1552 Fixes the CUMODE command when regaining founder privileges,
1553 and a little WHOIS problem.
1555 * Fixed silc_net_gethostbyname to correctly call the
1556 inet_ntop. Affected file lib/silcutil/silcnet.c.
1558 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1560 * Added IPv6 support checking to the configure.in.pre, added
1561 also --enable-ipv6 option to override the check. Affected
1562 file configure.in.pre.
1564 * The silc_thread_create now calls the start function
1565 directly if threads support is not compiled in. Removes
1566 ugly #ifdef's from generic code. Affected files are
1567 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1569 * Added silc_net_gethostby[name/addr]_async to asynchronously
1570 resolve. Affected files are lib/silcutil/silcnet.[ch].
1572 * Added support for rendering IPv6 based server, client and
1573 channel IDs. Affected file lib/silcutil/silcutil.c.
1575 * Added support for creating IPv6 based server IDs. Affected
1576 file is silcd/serverid.c.
1578 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1580 * Added silc_net_gethostby[addr/name] into the
1581 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1582 routines. Added silc_net_is_ip[4/6]. Affected file is
1583 lib/silcutil/unix/silcunixnet.c. All routines that take
1584 address as argument now supports both IPv4 and IPv6 addresses.
1586 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1588 * Fixed LIST command reply sending in server. Affected file
1591 * Server now sends the kicker's client ID in the KICK notify
1592 to the kicked client. Affected file silcd/command.c.
1594 * The client library now parses the kickers client ID and
1595 UI displays it. Affected files lib/silcclient/client_notify.c
1596 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1598 * Made all payload parsing function prototypes consistent.
1599 They all take now const unsigned char * and uint32 pair as
1600 the payload data instead of SilcBuffer. Changes all around
1601 the source tree. Other unsigned char* -> const unsigned char*
1602 changes around the tree as well.
1604 * Optimized SFTP client and server packet sending not to
1605 allocate new buffer for each packet but to recycle the
1606 first allocated buffer. Affected files are
1607 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1609 * Optimized the SFTP client to use SilcList instead of
1610 SilcDList for requests, because it is faster. Affected file
1611 is lib/silcsftp/sftp_client.c.
1613 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1614 into lib/silccore/silcid.[ch].
1616 Renamed silcpayload.[ch] into silcargument.[ch].
1618 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * If client entry is deleted with active key agreement
1621 session, abort the session.
1623 The silc_client_abort_key_agreement now calls the completion
1624 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1626 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1629 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * Don't use __restrict in older GCC's. Affected file is
1632 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1634 * silc_net_localhost now attempts to reverse lookup the
1635 IP/hostname. Affected file lib/silcutil/silcnet.c.
1637 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1638 command. It can be used to gain founder privileges at
1639 the same time when joining the channel.
1641 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1642 kicker's client ID as well. Updated protocol specs.
1644 Defined that the server must send SILC_COMMAND_IDENTIFY
1645 command reply with error status to client who sent
1646 private message with invalid client ID.
1648 Updated the protocol specification.
1650 * Added silc_server_send_command_reply to send any
1651 command reply. Affected file silcd/packet_send.[ch].
1653 * Added silc_id_payload_encode_data to encode ID payload
1654 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1656 * The server now send IDENTIFY command reply with error
1657 status if client ID in private message is invalid. Affected
1658 file silcd/packet_receive.c.
1660 * Save the server key file with server's IP address in
1661 the filename instead of hostname. The affected file is
1662 irssi/src/silc/core/client_ops.c.
1664 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1669 * Added libtool support for compiling shared objects in
1670 lib/silcsim. Affected file configure.in.pre and
1671 lib/silcsim/Makefile.am. Original patch by cras.
1673 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Pid file configuration, and server's config file fixes
1676 patch by toma. Updated CREDITS file.
1678 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1680 * Fixed silc_client_channel_message to not try to decrypt
1681 the message twice if it resolved the destination client
1682 information. This could cause of dropping one channel
1683 message. Affected file lib/silcclient/client_channel.c.
1685 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1688 lib/silcclient/client.c. This function is used when the SILC
1689 Client is run under some other scheduler, or event loop or
1690 main loop. On GUI applications, for example this may be
1691 desired to used to run the client under the GUI application's
1692 main loop. Typically the GUI application would register an
1693 idle task that calls this function multiple times in a second
1694 to quickly process the SILC specific data.
1696 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1698 * Fixed silc_server_drop() for dropping the supplementary
1699 groups as well, this could cause a security hole on some
1702 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1707 * Write PID file after dropping privileges. Added -F option
1708 to run server on foreground. A patch by debolaz.
1709 Affected files silcd/server.c, silcd/silcd.c.
1711 * Fixed MOTD to return the MOTD file server name. Affected
1712 file silcd/command.c.
1714 * Added INFO command reply handling to the Irssi SILC Client.
1715 Affected file irssi/src/silc/core/client_ops.c.
1717 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Fixed the silc_idcache_list_* routines to really support
1720 the dynamic list. Fixes a crash. Affected file is
1721 lib/silccore/silcidcache.c.
1723 * Fixed the LIST command reply to really call LIST command's
1724 pending callbacks. Affected file silcd/command_reply.c.
1726 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Update conn->local_entry->nickname after giving NICK
1729 command. Affected file lib/silcclient/command.c.
1731 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1733 * Added the [pid] option to the silcd configuration file
1735 Affected files: serverconfig.[ch] and silcd.c
1737 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Save fingerprint in WHOIS command reply in server.
1740 Affected file silcd/command_reply.c.
1742 * Fixed NICK commands pending callback registration.
1743 Affected file lib/silcclient/command.c.
1745 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Use ++server->cmd_ident when sending commands in server,
1748 instead of random number. Affected file silcd/command.c.
1750 * Fixed GETKEY command reply to call actually GETKEY pending
1751 command callbacks. Affected file silcd/command_reply.c.
1753 * A bit stricter check for nicknames. Check for same nickname
1754 in NICK command also. Affected file silcd/command.c.
1756 * Do not call INFO command everytime client ID changes, only
1757 during first connecting. Affected file lib/silcclient/client.c.
1759 * Set the new nickname only after successful command reply for
1760 NICK command is returned by server. Affected file
1761 lib/silcclient/command.c.
1763 * Remove nicknames from nicklist during server_signoff notify.
1764 Should fix /NAMES bit more. The affected file is
1765 irssi/src/silc/core/silc-channels.c.
1767 * Added `fingerprint' field to the SilcIDListData in the
1768 silcd/idlist.h to hold the fingerprint of the client's
1771 Send the fingerprint of the client's public key in WHOIS
1774 Affected files silcd/command.c, and silcd/idlist.[ch].
1776 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1777 create fingerprint from given data.
1779 * Show the fingerprint of the client's public key in WHOIS.
1780 Affected files irssi/src/module-formats.[ch] and
1781 irssi/src/silc/core/client_ops.c.
1783 * Format the multiple same nicknames also during JOIN and
1784 NICK_CHANGE notifys. Affected file is
1785 lib/silcclient/client_notify.c.
1787 * Do not print error on screen for invalid private message
1788 payload since it can come if someone is sending private
1789 messages with wrong key. Affected file
1790 lib/silccore/silcprivate.c.
1792 * Fixed multiple concurrent /PING crash. Affected file
1793 lib/silcclient/command.c.
1795 * Changed the wrong ID encoding. All IP addresses must be
1796 in MSB first order in encoded format. They were encoded
1797 wrong and was in LSB format. Affected files are
1798 silcd/serverid.c, lib/silcutil/silcutil.c.
1800 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1802 * Call the `connect' client operation through the scheduler
1803 in case of error. Affected file lib/silcclient/client.c.
1805 * Call the `failure' client operation even if the error
1806 occurred locally during a protocol. Affected file is
1807 lib/silcclient/protocol.c.
1809 * Added support of sending LIST command to router from normal
1810 server. This way normal server can get list of all channels
1811 in the network too. Fixed the channel list sending in the
1812 server too. Affected files are silcd/command.c, and
1813 silcd/command_reply.[ch].
1815 * Added silc_server_update_channels_by_server and
1816 silc_server_remove_channels_by_server. They are used during
1817 disconnection of primary router and in backup router protocol.
1818 Affected file silcd/server_util.[ch], silcd/server.c and
1819 silcd/server_backup.c.
1821 * Fixed channel adding to global list in IDENTIFY command
1822 reply in server. Affected file silcd/command_reply.c.
1824 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * If the incoming packet type is REKEY or REKEY_DONE process
1827 that packet always synchronously. Fixes yet another MAC
1828 failed error on slow (dialup) connections. Affected file
1829 lib/silcclient/client.c and silcd/server.c.
1831 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Call check_version SKE callback for initiator too. Affected
1834 file lib/silcske/silcske.c.
1836 * Implemented fix for security hole found in the SKE that was
1837 fixed in the specification few days back; the initiator's
1838 public key is now added to the HASH value computation.
1839 Added backwards support for the old way of doing it too, for
1840 old clients and old servers. Affected file is
1841 lib/silcske/silcske.c.
1843 * Enabled mutual authentication by default in SKE. If initiator
1844 is not providing mutual authentication the responder will
1845 force it. This will provide the proof of posession of the
1846 private key for responder. The affected files are
1847 lib/silcclient/protocol.c and silcd/protocol.c.
1849 * Do not cache anymore the server's public key during SKE.
1850 We do mutual authentication so the proof of posession of
1851 private key is done, and if the server is authenticated in
1852 conn auth protocol with public key we must have the public
1853 key already. Affected file silcd/protocol.c.
1855 * Added new global debug variable: silc_debug_hexdump. If
1856 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1857 file lib/silcutil/silclog.[ch].
1859 * Fixed compilation warning due to char * -> const char *.
1860 Affected files lib/silcutil/silcnet.h, and
1861 lib/silccore/silcauth.[ch].
1863 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Fixed CMODE command when new channel key was created. If
1866 the creation failed the old key was removed. Next time giving
1867 same command would crash the server since the old key was
1868 freed already. Affected file silcd/command.c.
1870 * Fixed the silc_server_announce_get_channels to not crash
1871 on reconnect. Affected file silcd/server.c.
1873 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Added silc_log_set_debug_string function to set a regex
1876 string to match for debug output. Only the function names,
1877 or filenames matching the given debug string is actually
1878 printed. This way it is possible to filter out those debug
1879 strings that user is not interested in.
1881 Fixed a bug in silc_string_regexify.
1883 Affected files lib/silcutil/silclog.[ch], and
1884 lib/silcutil/unix/silcunixutil.c.
1886 * Changed the -d options in both server and Irssi SILC client
1887 to take the debug string as argument. Affected files
1888 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1890 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Added silc_hash_babbleprint to create a Bubble Babble
1893 Encoded fingerprint. The encoding is developed by Antti
1894 Huima (draft-huima-babble-01.txt), and it creates human
1895 readable strings out of binary data. Affected file
1896 lib/silccrypt/silchash.[ch].
1898 * Print the babble print now in addition of fingerprint as well
1899 in Irssi SILC client. Affected files are
1900 irssi/src/fe-common/silc/module-formats.[ch],
1901 irssi/src/fe-common/silc/core/client_ops.c.
1903 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Fixed a security problem found in SKE. The initiator's
1906 public key too is now added to the HASH hash value creation
1907 which is signed by the responder to create the SIGN value.
1908 This will prevent anyone in the middle to lie to the responder
1909 about the initiator's public key. If this is done now, the
1910 man in the middle will get caught. Updated the protocol
1913 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1915 * Better installation directory handling. Configure module
1916 paths and other paths automatically to example_silc* files
1917 in doc/. A patch by toma.
1919 * Fixed compiler warning from MPI library, and from SILC RNG.
1922 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1923 It can be configured with ./configure. A patch by toma.
1925 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Find correct make to use in prepare-clean. A patch by
1928 toma. Affected file prepare-clean.
1930 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1932 * Added irssi variables use_auto_addr, auto_bind_ip,
1933 auto_bind_port and auto_public_ip.
1935 * Changed the interface for silc_client_send_key_agreement
1936 in lib/silcclient/silcapi.h
1940 irssi/src/silc/core/silc-core.c
1942 lib/silcclient/silcapi.h
1943 irssi/src/silc/core/silc-channels.c
1944 lib/silcclient/client_keyagr.c
1947 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Added silc_pkcs_public_key_compare to compare two
1950 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1952 * Check that the client who set the founder mode on the
1953 channel is the same client that is giving the founder
1954 mode to itself. It is done by comparing the saved public
1955 key (it is saved even in the authentication is passphrase).
1956 Affected file silcd/command.c.
1958 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1960 * Do not process packet for disconnected socket connection.
1961 Affected file lib/silccore/silcpacket.c.
1963 * Process the DISCONNECT packet through scheduler in the
1964 client library. Affected file lib/silcclient/client.c.
1966 * Fixed the silc_client_packet_parse to not to increase
1967 the packet sequence number if the conn->sock and the
1968 current socket connection is not same. This can happen
1969 for example during key agreement when the conn includes
1970 multiple socket connections (listeners). Affected file
1971 lib/silcclient/client.c.
1973 * The sender of the file transfer request now provides also
1974 the pointer (listener) for the key exchange protocol. If
1975 the listener cannot be created then it sends empty key
1976 agreement and lets the receiver provide the listener.
1978 Added `local_ip' and `local_port' arguments to the
1979 silc_client_file_send. If they are provided they are used,
1980 if not then it will attempt to find local IP address, if
1981 not found or bind fails then the remote client will provide
1984 Affected files are lib/silcclient/client_ftp.c and
1985 lib/silcclient/silcapi.h.
1987 * Extended the FILE SEND command to support defining the
1988 local IP and port for key exchange listener. They are
1989 optional. Affected file irssi/src/silc/core/silc-servers.c.
1991 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Defined to WHOIS command reply the sending of fingerprint
1994 of the client's public key (if the proof of posession of the
1995 corresponding private key is verified by the server).
1996 Updated to the protocol specification.
1998 * Added support of receiving the client's public key's
1999 fingerprint in command reply in client library. Affected
2000 file is lib/silcclient/command_reply.c, and
2001 lib/silcclient/idlist.[ch].
2003 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Do not send over 128 chars long nickname to the server
2006 in NICK command. Affected file lib/silcclient/command.c.
2008 * Do not send over 256 chars long channel names to the server
2009 in JOIN command. Affected file lib/silcclient/command.c.
2011 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2013 * Assure that silc_server_close_connection cannot be called
2014 twice for same socket context. Affected file is
2017 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Send error message to application if opening file for
2020 writing during file transfer fails. Affected file is
2021 lib/silcclient/client_ftp.c.
2023 Remove all file transfer sessions for a client that we're
2024 removing from ID cache.
2026 Affected file is lib/silcclient/client_ftp.c.
2028 * Fixed silc_net_addr2bin to return correct address. Affected
2029 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2031 * Fixed file transfer session removing on signoff notify.
2032 Affected file irssi/src/silc/core/silc-servers.c.
2034 * Added the SilcClientFileError to be returned in the monitor
2035 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2036 Affected file lib/silcclient/silcapi.h.
2038 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Fixed a crash in silc_client_ftp_free_sessions and
2041 silc_client_ftp_session_free_client. Affected file
2042 lib/silcclient/client_ftp.c.
2044 * Added `disabled' field in the SilcChannelEntry in the server
2045 to indicate if the server entry is disabled. Affected file
2046 silcd/idlist.h, silcd/command[_reply].c.
2048 * SILC server adds now /var/run/silcd.pid everytime it is
2049 started. Affected file silcd/silcd.c.
2051 * Added silc_server_packet_send_clients to send a packet to
2052 the provided table of client entries. Affected file
2053 silcd/packet_send.[ch].
2055 * Fixed a crash in client resolving in client_prvmsg.c in
2056 client library. Affected file lib/silcclient/client_prvmsg.c.
2058 * Do not actually remove the client directly from ID cache
2059 during SERVER_SIGNOFF, but invalidate it. This way we
2060 preserve the WHOWAS info for the client. Affected file
2061 silcd/server_util.c.
2063 * Fixed SERVER_SIGNOFF notify handling in the server. The
2064 server is now able to process incoming SERVER_SIGNOFF notify
2065 for a server that it doesn't even know about. It will remove
2066 the clients provided in the notify. Affected file
2067 silcd/packet_receive.c.
2069 * Check for partial packet in data queue after every packet that
2070 was found from the queue. Return and wait for more data if
2071 there is partial data in queue. Affected file is
2072 lib/silccore/silcpacket.c.
2074 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2076 * Added SilcClietFileError enum to indicate error in
2077 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2078 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2079 Affected files lib/silcclient/silcapi.h and
2080 lib/silcclient/client_ftp.c.
2082 * Check that newsize in silc_buffer_realloc is larger than
2083 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2085 * Added better monitor of file transfers. It now monitors
2086 key agreement protocol during the file transfer too. Added
2087 error reporting too. Affected files
2088 irssi/src/silc/core/silc-servers.c,
2089 irssi/src/fe-common/silc/module-formats.[ch].
2091 * Wrote a help file for FILE command.
2093 * Added silc_rng_global_get_byte_fast to get not-so-secure
2094 random data as fast as possible. Random data is read from
2095 /dev/urandom if available and from the SILC RNG if not
2096 available. It is used in padding generation. Affected file
2097 lib/silccrypt/silcrng.[ch].
2099 * All packets in client library are now processed synchronously.
2100 Optimized packet processing a lot. Affected file
2101 lib/silcclient/client.c.
2103 * All server connection packets are processing synchronously
2104 now in server, to optimize packet processing. Affected file
2107 * Include files are installed now only in Toolkit distribution
2108 if make install is given. Affected files: all Makefile.am's.
2110 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Assure that silc_client_notify_by_server_resolve does not
2113 resolve the client information multiple times. If it cannot
2114 be found by the first it cannot be found at all. Affected
2115 file lib/silcclient/client_notify.c.
2117 * Fixed WHOWAS command reply calling. Affected file
2118 lib/silcclient/command_reply.c.
2120 * Removed all references to silc_idlist_get_client from the
2121 Irssi SILC client since that call is internal call used by
2122 the library. The Irssi SILC client will use now client
2123 retrieval functions found in silcapi.h.
2125 * Fixed a bug in resolving nickname info before sending
2126 private message. It used freed memory. Affected file
2127 irssi/src/silc/core/silc-servers.c.
2129 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Assure my_channels statistics cannot go negative in server.
2132 Affected files silcd/server.c, silcd/server_util.c.

2148 * Added silc_net_localip to return local host's IP address.
2149 Affected file lib/silcutil/silcnet.[ch].
2151 * If key exchange or rekey protocol is active for a connection
2152 parse all packets syncronously since there might be packets
2153 in packet queue that we are not able to process without first
2154 processing packets before them. Affected file silcd/server,
2155 lib/silcclient/client.c.
2157 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2158 whether library should continue processing the packet.
2159 Affected file lib/silccore/silcpacket.h.
2161 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2162 SilcSFTPMonitorData to SFTP server to monitor various

2194 * Resolve the client info when received private message or
2195 channel message for a client which nickname we don't know.
2196 Affected files lib/silcclient/client_prvmsg.c and
2197 lib/silcclient/client_channel.c.
2199 * Do not crash in /KEY if client is not connected. Affected
2200 file irssi/src/silc/core/silc-channels.c.

2205 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2206 is incomplete and is being resolved, it won't be resolved
2209 Make sure also that USERS command reply does not resolve
2210 twice information. Affected file is
2211 lib/silcclient/command_reply.c.
2213 Make sure that silc_client_get_clients_by_list does not
2214 resolve twice same information.
2216 * Check for valid client->id in the silc_server_free_client_data.
2217 Affected file silcd/server.c.
2219 * Fixed /GETKEY nick@server not to crash if the server entry
2220 is not found. Affected file lib/silcclient/command.c.
2222 * Fixed the silc_server_check_cmode_rights to check the
2223 requested modes correctly. Affected file silcd/command.c.

2227 * Better checks for non-printable chars in nick added.
2228 Affected file silcd/command.c.
2230 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2232 * Call the silc_server_udpate_servers_by_server in the
2233 primary router that comes back online in the backup resuming
2234 protocol. Otherwise it routes packets wrong. Affected file
2235 silcd/server_util.[ch], silcd/server_backup.c.
2237 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2240 lib/silcutil/silcbuffmt.[ch].
2242 * Redefined the SILC packet header to include the padding
2243 length. Affected file lib/silccore/silcpacket.[ch].
2245 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2246 length for maximum padding up to 128 bytes). Affected
2247 file lib/silccore/silcpacket.h.
2249 * Removed all backwards support for old 0.5.x MAC thingies.
2250 The SILC packet header change makes it impossible to be
2251 backwards compatible.
2253 * Send the ENDING packet with timeout in the backup resuming
2254 protocol. This is to assure that all routers has connected
2255 to the primary router. Affected file silcd/server_backup.c.
2257 * Changed the RNG to take the first IV from random data. It
2258 used to take it from zero actually. Changed the RNG also
2259 to use /dev/urandom during session. /dev/random is used
2260 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2262 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2264 * Changed the SILC packet header to have the first two bytes
2265 (the packet length) encrypted. Affected files aroung the
2266 code tree, lib/silccore/silcpacket.[ch]. Removed the
2267 SilcPacketCheckDecrypt callback. It is not needed anymore
2268 since the silc_packet_receive_process will determine now
2269 whether the packet is normal or special.
2271 * Implemented the unidirectional MAC keys. Affected files
2272 lib/silcske/silcske.c, silcd/protocol.c and
2273 lib/silcclient/protocol.c.
2275 * Implemented the packet sequence number to the MAC computation.
2276 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2277 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2278 lib/silcclient/protocol.c.
2280 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Allow backup router to announce servers. All servers
2283 announced by backup router are added to the global list
2284 automatically. Update hte server's socket to our primary
2285 router also when backup router announces a server.
2286 Affected file silcd/packet_receive.c.
2288 * Do not update the client->router in the function
2289 silc_server_udpate_clients_by_server if the client is on
2290 global list. We might fail to find any specific server
2291 for locally connected clients and local cell clients. They
2292 should still use the `from' and not `to' as client->router.
2293 This fixes backup router resuming protocol. Affected file
2294 silcd/server_util.c.
2296 * Decrease channel statistics count only if the channel
2297 deletion worked. Affected files are silcd/server.c and
2298 silcd/server_util.c.
2300 * Added silc_server_update_servers_by_server to update origin
2301 of all server entries. Used during backup router protocol.
2302 Affected files silcd/server_util.[ch], silcd/server.c. and
2303 silcd/backup_router.c.
2305 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2306 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2307 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2308 lib/silccrypt/silchmac.c.
2310 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Assure that router cannot reroute the same channel message
2313 to the sender. Affected file silcd/packet_receive.c.
2315 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Made better checks that the channel message is not sent
2318 to the router it came from. Affected file is
2319 silcd/packet_send.c. Fixed memory leak too.
2321 * Announce informations for incoming router connection, but
2322 only after checking if it is replaced by backup router.
2323 Affected file silcd/packet_receive.c.
2325 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Fixed the backup resuming protocol to work in multiple
2328 router environment. Affected file silcd/server_backup.c.
2330 * Route packet only to one router in the function
2331 silc_server_packet_send_to_channel. Affected file is
2332 silcd/packet_send.c.
2334 * Fixed silc_server_send_notify_dest to set the broadcast
2335 flag. Fixed the silc_server_send_notify_topic to actually
2336 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2337 Affected file silcd/packet_send.c.
2339 * Changed the SFTP Filesystem interface. Changed the
2340 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2341 the filesystem operation function. The SilcSFTPFilesystem
2342 is now a context that is allocated by all filesystem allocation
2343 functions and it already includes the operations structure
2344 and filesystem specific context. It is given as argument
2345 now to the silc_sftp_server_start. This made the interface
2346 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2347 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2349 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2351 * Changed the backup router adding and getting interfaces
2352 in the server. The router that will be replaced by the
2353 specified backup router is now sent as argument. Affected
2354 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2357 * Added silc_net_addr2bin_ne to return the binary form of
2358 the IP address in network byte order. Affected files
2359 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2361 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2363 * Check for existing server ID in silc_server_new_server
2364 and in silc_server_connect_to_router_final and remove the
2365 old entry if it exists. Affected file silcd/packet_receive.c,
2368 * Send the channel message always to only one router, either
2369 in upstream or downstream. Affected file is
2370 silcd/packet_send.c.
2372 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Wrote the definition of the backup resuming protocol to the
2375 protocol specification.
2377 * Removed one redundant channel key generation from normal
2378 server during joining procedure. Removed one redundant
2379 channel key sending from server to router during joining
2380 procedure. Affected file silcd/command.c.
2382 * Made minor bugfixes to the backup router resuming protocol.
2383 Affected file silcd/server_backup.c, server.c.
2385 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Added --disable-asm configuration option. Affected files
2388 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2391 * Implemented the backup resuming protocol that is used to
2392 resume the primary router position in the cell after the
2393 primary router comes back online. Affected files
2394 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2395 and silcd/server_util.[ch].
2397 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Sleep two (2) seconds after sending QUIT command to server.
2400 Affected file lib/silcclient/command.c.
2402 * Assure that if outgoing data buffer is pending do not force
2403 send any data. Affected file silcd/packet_send.c.
2405 * Assure that if outgoing data buffer is pending do not force
2406 send any data. Affected file lib/silcclient/client.c.
2408 * Implemented the backup router support when the primary router
2409 goes down. The servers and routers can now use the backup
2410 router as new primary router without loosing connectivity.
2412 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2415 in the server to indicate disabled entry. All data read
2416 from the connection will be ignored and no data is sent
2417 for entry that is disabled. Affected files are
2418 silcd/idlist.h, silcd/server.c.
2420 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Created SFTP client and server test programs in the
2423 lib/silcsftp/tests directory.
2425 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Implemented memory filesystem (virtual filesystem) for
2428 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2431 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Implemented the SFTP (SSH File Transfer Protocol) to the
2434 lib/silcsftp. It includes SFTP client and SFTP server
2437 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Moved lib/silccore/silcprotocol.[ch] to the
2440 lib/silcutil library.
2442 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2443 take variable argument list pointer as argument. Affected
2444 file lib/silcutil/silcbuffmt.[ch].
2446 * Added silc_buffer_set function that is used to set data
2447 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2448 Affected file lib/silcutil/silcbuffer.h.
2450 * Changed various routines in the core library to use the new
2451 silc_buffer_set instead of allocating new buffer only for
2454 * Added 64-bit value formatting and unformatting support to the
2455 silc_buffer_[un]format routines. Affected file is
2456 lib/silcutil/silcbuffmt.[ch].
2458 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2459 to includes/bitmove.h.
2461 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Fixed channel user mode saving in client library. Affected
2464 file lib/silcclient/command[_reply].c.
2466 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Defined the file transfer to the SILC Protocol. Added
2469 new packet type SILC_PACKET_FTP and defined File Transfer
2470 Payload. The mandatory file transfer protocol is SFTP
2471 (SSH File Transfer Protocol). Affected file in addition
2472 of the internet draft is lib/silccore/silcpacket.h.
2474 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2475 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2476 is used as part of backup router protocol when the primary
2477 router of the cell is back online and wishes to resume
2478 the position as primary router.
2480 * Redefined the MAC generation keys in the protocol. The
2481 same key is not used anymore in both direction. Both
2482 direction will now use different keys for sending and
2483 receiving. This fixes a potential security flaw. This
2484 change causes incompatibilities in the protocol.
2486 * Redefined also the MAC computation from the packet.
2487 An packet sequence number is now added to the MAC
2488 computation. This prevents possible replay attacks against
2489 the protocol. This change too causes incompatibilities
2492 Added `sequence' field to the SilcPacketContext to hold
2493 the current sequence number for the packet.
2495 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Added `created' field to the SilcIDListData in the file
2498 silcd/idlist.h to indicate the time when the entry was
2501 * Added `created' field to the SilcChannelEntry too. Affected
2502 file silcd/idlist.h.
2504 * Added `creation_time' aguments to all the announcement functions
2505 in the server. If it is provided then only the entries that
2506 was created after the provided time frame are actually
2507 announced. Affected file silcd/server.[ch].
2509 * The protocol says that the Channel ID's IP address must be
2510 based on the router's IP address. Added check for this in
2511 the silc_server_new_channel when processing incoming New Channel
2512 Payload. Affected file silcd/packet_receive.c.
2514 * Print out the correct version with --version in SILC client.
2515 Affected file irssi/src/silc/core/silc-core.c.
2517 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Fixed WHOWAS command to check for completnes of the client
2520 entry always, not just when the command is coming from client.
2521 Affected file silcd/command.c.
2523 * Added new function silc_server_packet_queue_purge to purge the
2524 outgoing data queue to the network. After the function returns
2525 it is guaranteed that the outgoing packet queue is empty.
2526 Affected file silcd/packet_send.[ch].
2528 * Purge the outgoing packet queue in the rekey protocol's final
2529 callback to assure that all rekey packets go to the network
2530 before quitting the protocol. Affected file silcd/server.c.
2532 * Added silc_client_packet_queue_parse as similar function as
2533 in server to the client library. The affected file is
2534 lib/silcclient/client.c.
2536 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Splitted silcd/server.c and created silcd/server_util.[ch]
2539 for utility functions.
2541 * Added new socket flag SILC_SF_DISABLED to indicate that the
2542 connection is open but nothing can be sent to or received from
2543 the connection. Affected file lib/silcutil/silsockconn.[ch].
2544 The checking for disabled socket is checked in the low level
2545 silc_socket_write and silc_socket_read functions.
2547 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Allow only nicknames and channel names that fits into the
2550 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2552 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * When processing JOIN command reply in server check that if
2555 the channel exists in our global list we'll move it the local
2556 list. Affected file silcd/command_reply.c.
2558 * Fixed the check whether client is joined on the channel already
2559 in JOIN command. Affected file lib/silcclient/command.c.
2561 * Fixed the JOIN command reply to check whether the channel
2562 already exists. Affected file lib/silcclient/command_reply.c.
2564 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2566 * Added silc_ske_status_string to map the SKE error numbers
2567 to readable strings. The affected files are
2568 lib/silcske/silcske[_status].[ch].
2570 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Do not show the private channels on the WHOIS channel list
2573 as it is not allowed by the protocol. The affected file is
2576 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Assure that the packet length digged from the actual packet
2579 is something sensible in the silc_packet_decrypt_rest_special
2580 in lib/silccrypt/silcpacket.c.
2582 * Free and NULL the allocated pointer in silc_hmac_alloc if
2583 the HMAC allocation fails. The affected file is
2584 lib/silccrypt/silchmac.c.
2586 * Print the selected security properties to the log files in
2587 the server. Affected file silcd/protocol.c.
2589 * Add SKE's reference counter even if calling the completion
2590 callback manually. Otherwise it goes negative, although it
2591 does not cause any problems. The affected file is
2592 lib/silcske/silcske.c.
2594 * Remove the client entry with short timeout after giving the
2595 KILL command. Affected file lib/silcclient/command.c.
2597 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2598 case all found clients are already disconnected (WHOWAS would
2599 found them) in the server. Affected file silcd/command.c.
2601 * Update the last_receive (time of last data received) to be
2602 updated only when received private or channel message so that
2603 the idle time showed in WHOIS makes more sense.
2605 * Added boolean field `valid' in to the SilcClientEntry in the
2606 client library to indicate whether the entry is valid or not.
2607 This fixes the nickname change bug on channel when changing
2608 the nickname to be same than the old (like nick to Nick) the
2609 nickname formatter doesn't set the new nick anymore to Nick@host.
2610 Affected file lib/silcclient/idlist.[ch].
2612 * Now actually fixed the nickname changing on disconnection.
2613 Added new function silc_change_nick to the Irssi SILC Client.
2614 Affected file irssi/src/silc/core/client_ops.c,
2615 irssi/src/silc/core/silc-nicklist.[ch].
2617 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2619 * Check that the public key exists in the GETKEY command before
2620 trying to encode it. Affected file silcd/command.c.
2622 * Print some notifications on received public keys with GETKEY
2623 command in the Irssi SILC Client. Affected files are
2624 irssi/src/fe-common/silc/module-formats.[ch],
2625 irssi/src/silc/core/client_ops.c.
2627 * Use IDENTIFY command to resolve the server information in the
2628 GETKEY command instead of INFO command. Affected file
2629 lib/silcclient/command.c.
2631 * All command reply functions in the client library now calls
2632 the pending command reply callbacks even if an error has
2633 occurred. The server has done this a long time and now it was
2634 time to move the client library to this as well. Now all
2635 errors can be delivered back to the pending command reply
2636 callbacks if necessary. Affected files are
2637 lib/silcclient/command[_reply].[ch].
2639 * Change the nickname on disconnection back to the username
2640 because in reconnect the server will enforce it to it anyway.
2641 Affected file irssi/src/silc/core/silc-servers.c.
2643 * Fixed a config file parsing bug in the Irssi SILC client.
2644 Affected file irssi/src/silc/core/clientconfig.c.
2646 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * When printing the channel mode on JOIN, verify that the
2649 channel key and channel's HMAC are valid. Affected file
2650 irssi/src/silc/core/client_ops.c.
2652 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2655 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2656 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2658 * Removed channel key rekey task deleting from the function
2659 silc_server_save_channel_key. Affected file silcd/server.c.
2660 Added explicit timeout task context instead that is used to
2661 delete the task if we are registering a new task before the
2662 new task has elapsed.
2664 * When channel key rekey occurs the client library now saves
2665 the old channel key for a short period of time (10 seconds) and
2666 is able to use it in case some is still sending channel
2667 messages encrypted with the old key after the rekey. Affected
2668 file lib/silcclient/[idlist.h|client_channel.c].
2670 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Added check to the silc_server_new_id_real to not accept
2673 new ID if it is the sender's own ID. Affected file is
2674 silcd/packet_receive.c.
2676 * Assure that we do not announce ourself or the one we've
2677 sending our announcements when we're router and are announcing
2678 servers to our primary router. Affected file silcd/server.c.
2680 * Fixed silc_server_command_identify_check_client to assemble
2681 correct WHOIS packet. It send corrupted WHOIS packet and
2682 caused problem with router to router connections. Affected
2683 file silcd/command.c.
2685 Fixed also silc_server_command_whois_check the same way
2686 as for the IDENTIFY command.
2688 * Added new SilcIDListStatus to the server in the SilcIDListData
2689 structure. The status now includes the current status of
2690 the entry (like registered, resolved etc.). Affected file
2691 silcd/idlist.[ch]. Defined a bunch of different status types
2692 as well. This replaced the old boolean registered field as well.
2694 Added resolve_cmd_ident field to the SilcClientEntry structure
2695 too so that if the entry is for example being resolved so
2696 another command may attach to the same pending command reply
2697 without requiring to resolve the same entry again. This concept
2698 should optimize the WHOIS and the IDENTIFY resolving under
2699 heavy load by taking away unnecessary resolving for entries
2700 that are being resolved already.
2702 Added support for adding multiple pending commands for one
2703 command idenfier. Affected file silcd/command[_reply].[ch].
2705 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2706 before deleting the data. Otherwise the hash table will have
2707 freed data in comparison functions. Affected file is
2708 silcd/command_reply.c.
2710 * Fixed silc_idlist_replace_client_id to add the new entry to
2711 the cache with NULL nickname. Otherwise there will be invalid
2712 memory as the nickname after the nickname is freed. Affected
2713 file silcd/packet_receive.c.
2715 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2716 saved into wrong slots because the previous number of entries
2717 was not taken into account. Affected file silcd/idlist.c.
2718 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2720 * If we are router and we receive JOIN notify to a channel that
2721 does not have any users then notified client is marked as the
2722 channel founder, as it is it. The affected file is
2723 silcd/packet_receive.c
2725 * Added to the extended hash table API's table_del_*ext functions
2726 the destructor as argument too, so that the caller can decide
2727 which destructor to use or whether to use destructor at all.
2728 Affected file lib/silcutil/silchashtable.[ch].
2730 * Fixed ID Cache purging. It actually deleted the entries from
2731 the hash table after the data was freed. The hash table ended
2732 up comparing freed memory. The affected file is
2733 lib/silccore/silcidcache.c.
2735 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Fixed Irssi SILC client's KILL command's HELP syntax.
2739 * The USERS command now resolves the detailed user information
2740 if the userinfo field is missing. Affected file is
2741 lib/silcclient/command_reply.c.
2743 * Do not print error in silc_file_read if the read file does
2744 not exist. Just silently return NULL. Affected file is
2745 lib/silcutil/silcutil.c.
2747 * Fixed the silc_log_output to not wine about NULL filename
2748 and to not create some bogus " " filename. Affected file is
2749 lib/silcutil/silclog.c.
2751 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Fixed various printing bugs on the user interface in the
2754 Irssi SILC Client. Minor changes that were forgotten from
2757 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2759 * Fixed the configure.in.pre and the compilation and distribution
2760 environment to support the new autoconf 2.52. That version is
2761 now required to compile the CVS trunk.
2763 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2766 to generally parse user@fqdn format strings. Affected file
2767 lib/silcutil/silcutil.c.
2769 * Added nickname_format and nickname_force_format fields to the
2770 SilcClientParams structure. The first one defines the format
2771 for the nicknames that the library will enforce if the receives
2772 multiple same nicknames. The second one is boolean value and
2773 can be used to force the library to always enforce the format
2774 to the nicknames regardles whether there are multiple nicknames
2775 or not. This configurable formatting was employed to flexibly
2776 support accessing multiple nicknames from the user interface.
2777 The userinterface can now set the nicknames to what ever format
2778 they prefer. Affected file lib/silcclient/silcapi.h.
2780 Added function silc_client_nickname_format to the file
2781 lib/silcclient/idlist.c. It performs the nickname formatting.
2783 Added new field `hostname´ to the SilcClientEntry context.
2784 It holds the hostname of the client. Affected file is
2785 lib/silcclient/idlist.h.
2787 * Irssi SILC Client sets the nicknames in nick@hostn format.
2788 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2789 irssi/src/silc/core/silc-core.c.
2791 The WHOIS printing now also shows both the real nickname and
2792 the formatted nickname so that user knows how to access the
2793 user if there are multiple same nicknames cached. Affected
2794 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2795 printing formatting too to take the hostname now as a separate
2796 argument. The Affected file is
2797 irssi/src/fe-common/silc/modules-formats.[ch].
2799 * Changed the silc_client_get_clients_local to accept the formatted
2800 nickname as argument. It accepts the real nickname too but the
2801 formatted nickname can be used to find the true entry from
2802 multiple entries. Affected file lib/silcclient/silcapi.h and
2803 lib/silcclient/idlist.c.
2805 * Added nickname_format_parse field to the SilcClientParams.
2806 It is a callback function provided by the application to parse
2807 the nickname out of the formatted nickname string. The library
2808 calls it to get the nickname from the formatted string. Since
2809 the application generally knows better the format of the nickname
2810 string it parses it instead of the library, even though library
2811 encodes the formatted string. If the callback function is not
2812 provided then the library will use the string as is. The
2813 affected file is lib/silcclient/silcapi.h.
2815 * All the nickname strings passed to the client library in
2816 commands are now expected to be formatted nickname strings.
2817 If the command does not support the formatted nickname string
2818 it will assume that the sent string is the actual nickname.
2819 Affected file lib/silcclient/command.c.
2821 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Added public key authentication support to OPER and SILCOPER
2824 commands in the client library. Affected file is
2825 lib/silcclient/command.c.
2827 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Changed the get_auth_methdod client operation to be asynchronous.
2830 It can be async if the application resolves the authentication
2831 method from the server during the negotiation. Added new
2832 SilcGetAuthMeth completion callback that the application will
2833 call after resolving the authentication method.
2835 Added function silc_client_request_authentication_method that
2836 the application can use to resolve the authentication method
2837 from the server. Added also SilcConnectionAuthRequest callback
2838 that the library will call after the server has replied. The
2839 application can call this function if it does not know the
2840 current authentication method.
2842 Affected files are lib/silcclient/client.c and
2843 lib/silcclient/silcapi.h.
2845 * The Irssi SILC client now automatically resolves the authentication
2846 method incase any configuration information is not present (and
2847 currently there never is). The affected file is
2848 irssi/src/silc/core/client_ops.c.
2850 * Fixed public key authentication from the client library.
2851 Affected file lib/silcclient/protocol.c. Changed also the
2852 protocol specification about the public key authentication in
2853 the connection authentication protocol. The actual data to be
2854 signed is now computed with a hash function before signing.
2856 * Fixed the public key authentication from the server as well.
2857 Affected file silcd/protocol.c.
2859 * Removed the mlock()'s from the memory allocation routines.
2860 Affected file lib/silcutil/silcmemory.c. The ./configure does
2861 not check anymore for the mlock(). Affected file is
2864 * Fixed USERS command in server to allow the execution of the
2865 command for private and secret channels if the client sending
2866 the command is on the channel. Affected file silcd/command.c.
2868 * Fixed silc_client_get_clients_local to return the clients
2869 count correctly. It could return wrong value. Affected file
2870 lib/silcclient/idlist.c.
2872 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2875 types. The assembler optimizations seemed not to like 64-bit
2876 data types. The assmebler optimizations thus are now enabled
2877 also for BSD systems as opposed to only enable them for Linux.
2879 * Do not check for threads at all on BSD systems. Affected
2880 file configure.in.pre.
2882 * Removed -n and -h options from the Irssi SILC Client since
2883 they are not used in silc.
2885 * Fixed the prime generation to assure that the first digit
2886 of the generated random number is not zero since our conversion
2887 routines does not like number strings that starts with zero
2888 digit. If zero digit is seen the random number is regenerated.
2889 This caused some corrupted RSA keys when the zero first digit
2890 was met. Affected file lib/silcmath/silcprimegen.c.
2892 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * Fixed WIN32 configuration in the ./configure script.
2895 Fixed to include xti.h on environments that has it.
2896 Patches by Carsten Ilchmann and andrew.
2898 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Changed the silc_id_create_client_id to be collision
2901 resistant. It is now assured that there cannot be created
2902 two same client ID's. I suspect that some weird bugs in
2903 the server were actually caused by duplicate Client IDs.
2904 Affected file silcd/serverid.[ch]. A router receiving
2905 new ID now also assures and informs the sending server
2906 if the ID caused collision.
2908 * Changed the silc_id_create_channel_id to also assure that
2909 there are no collisions.
2911 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Statement about ignoring the Mutual Authentication flag when
2914 performing rekey with PFS was a bit misleading. It is ignored
2915 if it was set in the initial negotiation, it cannot be even
2916 set in the rekey. Fixed in the ke-auth draft. Started the
2917 new versions of the protocol drafts in the doc/.
2919 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Fixed a bug in silc_client_command_identify_save when saving
2922 new channel information. The channel name was no duplicated
2923 and caused crash on exit. Affected file is
2924 lib/silcclient/command_reply.c.
2926 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * Fixed the getkey command handling in the server. Send just
2929 empty OK reply to the sender if the key could not be fetched
2930 (but everything else was ok, like the key just was not available).
2931 Changed the public key parameter to optional in the protocol
2932 specs so that empty OK reply can be sent. Affected file
2935 Added a message to Irssi SILC client to tell to user if the
2936 server did not return a public key.
2938 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * Fixed a channel key regeneration bug. It registered new
2941 timeout tasks exponentially until all system resources were
2942 used. Affected file silcd/server.c.
2944 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Added the SILC Document generator to the scripts/silcdoc.
2947 It can be used to generate the Toolkit Reference Manual out
2948 of the source tree. Internally it will also use the RoboDoc
2949 generator now imported in util/robodoc.
2951 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Added couple of return's in rekey protocol if error orccurred
2954 during the protocol. The execution must be terminated.
2955 Affected file silcd/protocol.c. Also, terminate the protocol
2956 always with timeout.
2958 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * The client's Client ID was created initally from the wrong
2961 nickname (it could have been in format nick@host) in the
2962 silc_server_new_client. Affected file silcd/packet_receive.c
2964 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Added some SILC_LOG_ERROR's to various error conditions
2967 if client could not be added to ID cache. Affected files
2968 silcd/packet_receive.c and silcd/server.c.
2970 * When client's sock->user_data is freed, NULL also the
2971 client->router and client->connection pointers. Added check
2972 for these pointers being NULL to various places around the
2973 code. Affected file silcd/server.c.
2975 * Added client->data.registered == TRUE checks to various
2976 places around the code to assure that unregistered client's
2977 are not handled when it is not allowed. Affected file
2980 * Added `bool registered' fields to all
2981 silc_idlist_[server|client]_get_* routines to indicate whether
2982 the fetched client needs to be registered or not. Affected
2983 file silcd/idlist.[ch].
2985 * Add your own entry as registered to the ID cache in the
2986 server. Affected file server.c.
2988 * Fixed a bug in silc_server_new_server. The SilcServer was
2989 set as the new server's context instead of SilcServerEntry.
2990 This naturally caused some weird bugs.
2992 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Do not delete the channel rekey task when adding it
2995 for in silc_server_create_channel_key.
2997 * Changed the silc_server_create_channel_key to return
2998 TRUE or FALSE to indicate the success of the channel key
3001 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * Fixed MSVC++ project files and added missing files to
3004 Makefiles under win32/.
3006 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Do not add TCP_NODELAY flag if the operating system
3009 does not have it defined. Affected files are
3010 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3012 * Fixed buffer overflow from Irssi SILC Client. Affected
3013 file irssi/src/fe-common/core/themes.c.
3015 * Fixed double free in client library in the file
3016 lib/silcclient/client.c when disconnecting from server.
3018 * Applied double free patch from cras to Irssi SILC client.
3019 Affected files irssi/src/core/[modules/expandos].c
3021 * Fixed the disconnection handling to Irssi SILC Client.
3022 The application must call silc_client_close_connection
3023 in ops->connect client operation in case of failure of
3024 the connection. Affected file is
3025 irssi/src/silc/core/client_ops.c.
3027 * Do not set sock->protocol to NULL in the function
3028 silc_client_close_connection after executing the protocol's
3029 final callback since the sock might not be valid anymore.
3030 Affected file lib/silcclient/client.c.
3032 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Do not enable SILC_THREADS if the linking with libpthread
3035 did not happen. Affected file configure.in.pre.
3037 * Added notion to protocol specification that server must
3038 verify the sent authentication payload with CMODE when
3039 setting the channel founder key. Implemented it to the
3040 server. Affected file silcd/command.c.
3042 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Added _EXTRA_DIST SILC distribution variable to the
3045 distributions file. It is used to conditionally add extra
3046 files or directories to the specific distribution. Affected
3047 files ./prepare, Makefile.am.pre and distributions.
3049 Removed the `_' from the start of the distribution names.
3052 * Added README.WIN32 for instructions to compile the Toolkit
3055 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Fixed a double free in disconnection in the server. Affected
3058 file is silcd/server.c.
3060 * Fixed the lib/silcske/groups.c to work now also with GMP
3061 MP library. The string conversion did not work when using
3062 specific base and the base is indicated in the string as well.
3064 * Created win32/ directory which now includes MSVC++ specific
3065 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3066 It will appear only in the toolkit distribution
3068 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Changed the key material distribution function in case when
3071 the hash output is too short. The data is now concatenated
3072 a bit differently than it used to. Made the change to the
3073 SKE protocol specification.
3075 * Added better GMP detection to configure.in.pre. A patch
3078 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Fixed a minor bug in SKE that might cause some problem on
3081 some platforms. Affected file lib/silcske/silcske.c.
3083 * Added the cookie checking for initiator in the SKE. It checks
3084 that the responder returns the sent cookie unmodified. The
3085 affected file is lib/silcske/silcske.c. Added new SKE
3086 error type INVALID_COOKIE that can be sent during the
3087 negotiation. Fixed some memory leaks as well.
3089 * Added the "invalid cookie" error message to Irssi SILC client's
3092 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Added `task_max' field to the SilcClientParams to indicate
3095 the maximum tasks the scheduler can handle. If set to zero,
3096 default values are used. Affected file lib/silcclient/silcapi.h.
3098 * Fixed memory leaks in silc_client_close_connection. Affected
3099 file lib/silcclient/client.c.
3101 * Added silc_client_del_client_entry to client library to free
3102 all memory of given client entry. Affected file is
3103 lib/silcclient/idlist.[ch].
3105 * Added new functions silc_client_del_channel and
3106 silc_client_del_server to delete channel and server entries.
3107 Affected file lib/silcclient/[silcapi.h/idlist.c].
3109 * Removed silc_client_del_client_by_id from silcapi.h.
3111 * Fixed the INFO command to return the server's own info
3112 correctly when querying by Server ID. Affected file is
3115 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Removed the non-blocking settings in WIN32 code in the
3118 silc_sock_[read/write] and added SleepEx instead. Affected
3119 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3120 of input data is now checked with FIONREAD and ioctlsocket.
3122 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Call silc_schedule_task_del_by_context in the
3125 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3126 Affected file lib/silccore/silcprotocol.c.
3128 * Call silc_protocol_cancel for active protocols in the
3129 silc_server_close_connection if the funtion
3130 silc_server_free_sock_user_data has not been called.
3131 Affected file silcd/server.c.
3133 * Generic tasks cannot be deleted using the del_by_fd
3134 task deleting function since generic tasks does not match
3135 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3137 * Added a notion to SILCOPER help file that the SILCOPER works
3138 only on router server, not on normal server.
3140 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * Added for WIN32 support for the new scheduler as well.
3143 Affected file lib/silcutil/win32/silcwin32schedule.c.
3145 * Fixed the SHA1 implementation to work on various platforms.
3147 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3149 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3150 API. It is part of the scheduler now. Everything else is
3151 as previously but some functions has changed their names.
3152 Checkout the lib/silcutil/silcschedule.h for the interface.
3153 Updated all applications to use the new interface. Affected
3154 files are lib/silcutil/silcschedule.[ch].
3156 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3158 * Found a bug in the SKE implementation. The HASH value,
3159 specified by the protocol, was not computed correctly. The
3160 public key of the responder was not added to the computation
3161 even though it is mandatory. Affected file lib/silcske/silcske.c.
3162 This unfortunately causes incompatibilities with older
3163 clients and servers.
3165 * Added WIN32 specific network init and uninit functions:
3166 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3167 the Winsock2. Affected file lib/silcutil/silcnet.h and
3168 lib/silcutil/win32/silcwin32net.c.
3170 * Set the socket always to nonblocking mode on WIN32 after
3171 reading data or writing data. Affected file is
3172 lib/silcutil/win32/silcwin32sockconn.c.
3174 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Fixed various compilation problems under WIN32. Affected
3177 files lib/silcutil/win32/silcwin32thread.c and
3178 lib/silcutil/win32/silcwin32schedule.c.
3180 * Removed all _internal.h #includes from public header
3181 files. Internal headers must never be included from
3184 Removed also the lib/silcske/payload_internal.h file.
3186 * All include files that may be needed (public and some others
3187 included by the public headers) by application developers are
3188 now copied to the ./includes directory. It does not copy any
3189 internal headers. Affected file Makefile.defines.pre and all
3190 Makefile.am's under lib/ and subdirs.
3192 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Do not change the ~/.silc directory's permissions automatically.
3195 Affected file irssi/src/silc/core/clientutil.c.
3197 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3199 * Do not cancel the protocol in silc_server_close_connection
3200 it might cause recursion. Now cancelled in the function
3201 silc_server_free_sock_user_data. Affected file silcd/server.c.
3203 * Fixed the silc_server_remove_clients_by_server to regenerate
3204 the channel keys correctly finally. Added also new function
3205 silc_server_remove_clients_channels to actually do it.
3206 Affected file silcd/server.c.
3208 * Fixed the silc_server_new_channel to not crash by giving
3209 wrong router to the new channel. Affected file is
3210 silcd/packet_receive.c.
3212 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3215 which is given as argument to the silc_client_alloc now.
3216 It can be used to configure the client and set various parameters
3217 that affect the function of the client.
3219 * The USERS command in server did not check whether the channel
3220 is private or secret. Affected file silcd/command.c.
3222 * Added new argument to the USERS command in protocol specification.
3223 The USERS command now can take the channel name as argument
3224 as well. Added support for this in client and server and
3225 updated the protocol specs.
3227 * Completed the GETKEY command in client. It can be now used
3228 to fetch also servers public key not only some clients.
3229 Affected files lib/silcclient/command[_reply].c.
3231 * Added silc_client_get_server to return server entry by the
3232 server name. Affected files lib/silcclient/silcapi.h and
3235 * Redefined the IDENTIFY command in protocol specification to be
3236 more generic. It now can be used to query information about
3237 any entity in the SILC Network, including clients, servers and
3238 channels. The query may be based either the entity's name
3239 or the ID. Added support for this in both client and server.
3241 Affected files silcd/command.c and lib/silcclient/command.c
3242 and command_reply.c.
3244 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3245 the _from_client and _from_server functions. Affected file
3248 * Added silc_client_get_channel_by_id_resolve to the file
3249 lib/silcclient/silcapi.h to resolve channel information by
3250 its ID. Added also silc_client_get_channel_by_id that
3251 does not resolve it from the server.
3253 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Added SilcServerEntry context into the client library
3256 to represent one server. The INFO command now allocates
3257 these to save the resolved server info. For now on the
3258 client library will also keep information about servers,
3259 connected and resolved with INFO.
3261 The INFO command now allocates the SilcServerEntry context
3262 and saves the server info there. The COMMAND_REPLY in
3263 the INFO now returns the parameters to application in
3264 same order as defined in the protocol specification.
3266 The entries are cached in the client->server_cache.
3268 * The INFO command is now issued after received the Client ID
3269 from the server. Affected file lib/silcclient/client.c.
3271 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3272 to the application as the mode changer might be server.
3273 It is guaranteed that NULL is not returned anymore to the
3274 application. Affected file lib/silcclient/client_notify.c.
3276 The ID Type is now also passed to the application so that
3277 it can check whether the returned entry is SilcClientEntry
3280 Added new function silc_client_get_server_by_id to return
3281 the server entry by ID. Affected files are the
3282 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3284 * Do not create the channel in the Irssi SILC Client when issuing
3285 the JOIN command but when received the sucessful JOIN command
3286 reply. Otherwise the channel might get created even though we
3287 could not join it. The Affected file is
3288 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3290 * Fixed a channel joining bug in router. The router must also
3291 check the channel modes, invite and ban lists etc. when serving
3292 the JOIN command sent by normal server. Affected file is
3293 silcd/command.c. The router now resolves the client's
3294 information from the server who sent the JOIN command if it
3295 does not know it, and processes the JOIN command only after
3298 * Changed the SilcCommandCb to take new argument; void *context2.
3299 Affected file lib/silccore/silccommand.h
3301 The second argument in the command callbacks in the server now
3302 includes the SilcServerCommandReplyContext if the command was
3303 called as pending command callback from the command reply.
3304 Otherwise it is NULL. When called as pending the status of the
3305 command reply will be checked and if it was erronous the
3306 error will be sent to the original sender of the command.
3307 This way the client always receives the error messages even
3308 though the server was actually the one who received the error
3309 when it resent the command to router, for example. Affected
3310 files silcd/command[_reply].[ch].
3312 * Fixed sending WHOWAS command's error message to client if
3313 the requested client could not be found. It was missing.
3316 * Changed the CMODE and CUMODE commands reply arguments in the
3317 protocol specification. The Channel ID is now sent in both
3318 of the commands to identify the channel. Implemented this
3319 new feature to the client and server. Affected files
3320 lib/silcclient/command_reply.c and silcd/command.c.
3322 * Made better checks for invite and ban lists in the JOIN
3323 command in server. Affected file silcd/command.c.
3325 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * The server now performs the incoming host IP/DNS lookup
3328 using the silc_socket_host_lookup and thus does not block
3329 the server anymore. Affected file silcd/server.c.
3331 * Completed the multi-thread support for SILC Scheduler in
3332 the lib/silcutil/silcschedule.c.
3334 * Fixed the configure.in.pre to detect the pthread correctly
3337 * Fixed a deadlock in silc_task_queue_wakeup in the file
3338 lib/silcutil/silctask.c.
3340 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3342 * Added new function silc_schedule_wakeup that is used in
3343 multi-threaded environment to wakeup the main thread's
3344 schduler. It needs to be used when a thread adds a new task
3345 or removes a task from task queues. After waking up, the
3346 scheduler will detect the task queue changes. If threads
3347 support is not compiled in this function has no effect.
3348 Implemented the wakeup mechanism to both Unix and WIN32
3349 systems. Affected files are lib/silcutil/silcschedule.[ch],
3350 lib/silcutil/unix/silcunixschedule.c and the
3351 lib/silcutil/win32/silcwin32schedule.c.
3353 * Added new function silc_task_queue_wakeup to wakeup the
3354 scheduler by the specified task queue. Affected file
3355 lib/silcutil/silctask.[ch].
3357 * The silc_socket_host_lookup_start now wakes up the scheduler
3358 after adding the timeout task. Affected file is
3359 lib/silcutil/silcsockconn.c.
3361 * The silc_socket_host_lookup is synchronous now if the threads
3362 support is not compiled in. However, the callback is still
3363 called asyncronously through the scheduler, anyway. Affected
3364 file lib/silcutil/silcsockconn.c.
3366 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Added new function silc_socket_host_lookup to perform
3369 asynchronous IP and FQDN lookups for the socket connection.
3370 Affected files lib/silcutil/silcsockconn.[ch].
3372 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3375 that may or may not compile the mutex support in.
3377 Changed the silc_mutex_alloc interface. It allocates the
3378 mutex now to the sent pointer and returns TRUE or FALSE.
3380 Affected file lib/silcutil/silcmutex.h.
3382 * Wrote the SILC Task Queue interface to support multi-threads.
3383 Affected file lib/silcutil/silctask.[ch].
3385 * Wrote the SILC Scheduler to support multi-threads. Affected
3386 file lib/silcutil/silcschedule.c.
3388 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3391 in lib/silcutil/win32/.
3393 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Defined SILC Mutex API and SILC Thread API and implemented
3396 them for Unix. Affected files are
3397 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3398 lib/silcutil/unix/silcunixmutex.c and
3399 lib/silcutil/unix/silcunixthread.c.
3401 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3403 * Fixed the silc_server_remove_clients_by_server's channel
3404 key re-generation. The hash table handling was incorrect
3405 and would not work with many channels. Affected file is
3408 * Fixed some memory leaks around the server code.
3410 * Rewrote the silc_server_get_users_on_channel to support IPv6
3411 based Client ID's. Affected file silcd/server.c.
3413 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3414 specification. However, a separate document must be written
3415 to define the detailed signing procedure and the payload
3416 associated with the flag. Defined the flag to the
3417 lib/silccore/silcchannel.h as well.
3419 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Changed the dynamic tables to static size tables in the
3422 lib/silccrypt/silchmac.c.
3424 * Removed GCC dependencies from the code. A patch by cras.
3426 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * Do not show the error "Error receiving packet bla bla"
3429 in server if it really was not an error (-2 means that reading
3430 is pending). Affected file silcd/server.c.
3432 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Fixed a possible crash in silc_server_remove_clients_by_server
3435 in silcd/server.c. Fixed there also some memory leaks.
3437 * Fixed the silc_idlist_replace_client_id. It could replace
3438 wrong key in the hash table. Affected file silcd/idlist.c.
3440 * Do not check whether there are global users on the channel
3441 if the channel->global_users is FALSE. Affected functions
3442 silc_server_remove_from_one_channel and
3443 silc_server_remove_from_channels in silcd/server.c. Also,
3444 do not check if the removed client is local as we can be
3445 sure that global client was not removed from the channel
3446 and checking for global users is not needed.
3448 * The silc_server_remove_clients_by_server now re-generates
3449 the channel keys correctly for those channels that had
3450 clients removed from them. Affected file silcd/server.c.
3452 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * Found the reason of random crashes in the server. We weren't
3455 ignoring the SIGPIPE signal (which can be sent in write())
3456 and it crashed the server. Affected file silcd/silcd.c.
3458 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3460 * Assure that sock->user_data is not NULL in the function
3461 silc_server_packet_send in silcd/packet_send.c.
3463 * Disconnect the remote connection if it could not be added
3464 to any ID lists in the server. The affected file is
3467 * Check in silc_server_packet_send[_real/dest] that the
3468 socket is not disconnecting and ignore the data if it is.
3469 Affected file silcd/packet_send.c.
3471 * Define inline to __inline on native WIN32 compilation.
3472 Affected file includes/silcwin32.h.
3474 * Added some explicit type casts for inline code since MSVC
3475 require them. Affected files lib/silcutil/silcbuffer.h,
3476 lib/trq/silcdlist.h and lib/trq/silclist.h.
3478 * Print warning in log files from now on if the packet
3479 decryption fails. Affected file silcd/server.c.
3481 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3483 * Changed the `say' client operation's interface to accept
3484 new `type' argument to indicate the type of the message sent
3485 by the library. The application may filter the library's
3486 messages according the type. The affected file is the
3487 lib/silcclient/silcapi.h.
3489 * Added two new functions to lib/silcclient/silcapi.h:
3490 silc_client_del_client and silc_client_del_client_by_id.
3491 Affected file lib/silcclient/idlist.c.
3493 * Moved the clientincludes.h from includes/ to silc/ and
3494 serverincludes.h from includes/ to silcd/.
3496 * The modes for the CMODE and CUMODE are now passed as
3497 uint32 for application with COMMAND_REPLY. The affected
3498 file is lib/silcclient/command_reply.c.
3500 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3502 * /WHOIS without arguments shows client's own information.
3503 Affected file lib/silcclient/command.c.
3505 * Changed PING to not accept any arguments. The specs
3506 says that client can ping only the connected server so
3507 requiring an argument is not needed. Affected file is
3508 lib/silcclient/command.c.
3510 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Fixed a fatal bug in private message sending and reception
3513 encryption and decryption when using private message keys.
3514 The implementation was incorrect and did not follow the
3515 specification. It causd that some of the message were
3516 lost since it did not use the sending and receiving keys
3517 as the protocol suggests. This has been fixed and will cause
3518 incompatibilities with older clients when sending private
3519 message encrypted with private message keys. Affected files
3520 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3521 and various other in Irssi SILC Client.
3523 Added `responder' boolean argument to the functions
3524 silc_client_add_private_message_key[_ske] to indicate when
3525 the key is added as responder or initiator of the key
3528 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3530 * Removed the silc_ske_check_version function and created
3531 a SilcSKECheckVersion callback. Added also a function
3532 silc_ske_set_callbacks that is now used to set all SKE
3533 callbacks. The callback functions are not given to
3534 the SKE functions anymore, but this function is used to
3537 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3539 * Added `silc_version' argument to the silc_client_alloc
3540 to define the version of the application for the library.
3541 The library will use the version string to compare it
3542 against the remote host's (usually a server) version
3543 string. Affected file lib/silcclient/silcapi.h
3545 * Added the KE protocol context to Key Agreement context
3546 in client library so that we can abort the SKE if it
3547 is in process when we get timeout. Affected file is
3548 lib/silcclient/client_keyagr.c.
3550 * Do not resolve the client ID forever if it returns in the
3551 first time that such client does not exist. This was done
3552 for example with private message. Affected file is
3553 lib/silcclient/client_prvmsg.c.
3555 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Do not add regex.h for WIN32. The affected file
3558 includes/silcincludes.h.
3560 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3561 not work yet 100%. It generates the DLL's automatically
3562 when compiling with --with-win32 under cygwin.
3564 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * lib/contrib/regex.c is not compiled on WIN32.
3568 * Added silc_net_get_socket_opt function to the
3569 lib/silcutil/silcnet.h.
3571 * Added includes/silcwin32.h for WIN32 specific includes
3574 * Do not use ptime structure or any of the posix process
3575 functions on WIN32 in lib/silccrypt/silrng.c.
3577 * Added silc_gettimeofday to provide generic function
3578 for struct timeval on all platforms. Added the function
3579 to lib/silcutil/silcutil.h.
3581 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3583 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3584 library as they clearly belong there. As a plus side we
3585 can make the actual socket connection routines platform
3588 Added also new generic function silc_socket_read and
3589 silc_socket_write (that used to be silc_packet_[read/write].
3590 The implementation of these are platform specific.
3592 * Added WIN32 specific routines of silc_socket_[read/write]
3593 to lib/silcutil/win32/silcwin32sockconn.c.
3595 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Added preliminary support for native WIN32 compilation under
3598 cygwin (using the -mno-cygwin option for GCC) to the
3599 ./configure.in.pre. The --with-win32 now prepares the
3600 compilation for native WIN32.
3602 * Rewrote the SILC Scheduler interface in the file
3603 lib/silcutil/silcschedule.h. The scheduler is now context
3604 based and does not have anymore any global static scheduler.
3605 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3606 and created lib/silcutil/win32 directory for WIN32 based
3609 * Added Unix specific network routines to the
3610 lib/silcutil/unix/silcunixnet.c and the old
3611 lib/silcutil/silcnet.c includes now only generic routines.
3613 Added WIN32 specific network routines to the
3614 lib/silcutil/win32/silcwin32net.c.
3616 * Added Unix specific utility functions from the
3617 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3619 * Added WIN32 SILC Scheduler to the file
3620 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3623 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3625 * Do not handle JOIN notify in the server if the target client
3626 is not registered (idata->registered == FALSE). The affected
3627 file is silcd/packet_receive.c.
3629 * Update the nickrec->founder in event_cumode in the Irssi SILC
3630 client. Affected file irssi/src/silc/core/silc-channels.c.
3632 * Fixed the CUMODE_CHANGE notify handling in the server when
3633 server and router are announcing their clients on channels.
3634 Now the mode changes are saved and notified correctly. The
3635 affected file is /silcd/packet_receive.c.
3637 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3638 They really did not replace the cache entry in the ID Cache.
3639 Now they do that. Affected file silcd/idlist.c.
3641 * Fixed the KICK notify handling in the Irssi SILC client to
3642 update the channel records so that the kicked client does not
3643 appear to be on the channel. The affected file is
3644 irssi/src/silc/core/silc-channels.c.
3646 * Always update the conn->current_channel when executing command
3647 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3649 * Fixed the KILL notify handling in Irssi SILC client to remove
3650 the killed client on all channels.
3652 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Fixed the silc_parse_command_line to remove extra spaces
3655 from the start and end of the arguments. Affected file is
3656 lib/silcutil/silcutil.c.
3658 * Cancel and free any active protocol in the function
3659 silc_server_close_connection. Affected file silcd/server.c.
3661 * Cancel and free any active protocol in the function
3662 silc_client_close_connction. Affected file is
3663 lib/silcclient/client.c.
3665 * Do not execute the KILL command for clients that are in
3666 history (ie. they are not in the network). Affected file is
3669 * Fixed KILL notify handling, client does not crash anymore.
3670 Affected file irssi/src/silc/core/silc-channels.c.
3672 * Reduced the default packet buffer size from 2048 to 1024 in
3673 lib/silccore/silcpacket.c.
3675 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3676 counter to the SKE context that is incresed when the SKE library
3677 performs async operation outside the library. If the outside
3678 process frees the SKE context and FREED status will be set
3679 and the library will detect after the sync operation that the
3680 libary is freed. The affected files are
3681 lib/silcske/silcske[_status].[ch].
3683 * Resolve the client entry information in the function
3684 silc_client_channel_message to assure that NULL pointer is not
3685 passed as client entry to the application. */
3687 * Fixed the task timeout calculation to assure that there is
3688 never negative timeouts. The affected file is
3689 lib/silcutil/silcschedule.c.
3691 * Fixed the channel user mode notification sending in server.
3692 It was sent point-to-point to the router (or to server by router)
3693 but it needs to be destined to a channel. The routines now
3694 supports sending the channel user mode notifys to the channels
3695 when announcing clients and channels. Affected files are
3696 silcd/server.c and silcd/packet_receive.c.
3698 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3699 It did not actually replace the old channel entry in the cache.
3700 Affected file lib/silcclient/client_notify.c.
3702 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Fixed a possible crash in silc_packet_send_prepare. It now
3705 assures always that there is enough space in the buffer and
3706 at the tail area of the buffer (for MAC).
3708 Fixed the inbound buffer reallocation in silc_packet_read.
3709 It was old code and did not handle the reallocation correctly.
3712 The affected file is lib/silccore/silcpacket.c.
3714 * Fixed buffer overflow in silc_parse_nickname in the file
3715 lib/silcutil/silcutil.c.
3717 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * make install generates new server keys only if there is not
3722 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3725 Added check that if the NOREPLY is set then we will not send
3726 the away message. This avoids infinite loop of away messages
3727 if both clients are away. The affected file is
3728 lib/silcclient/client_prvmsg.c.
3730 * Fixed client crash if /NICK was given without arguments.
3731 Affected file lib/silcclient/command.c.
3733 * Server does not send the invite list in INVITE command back
3734 to the client if the list was not altered. Added this notion
3735 to the protocol spec as well. Affected file silcd/command.c.
3737 Fixed possible crash in INVITE command by checking the
3738 value of silc_server_get_client_route command.
3740 * Fixed the INVITE notify type handling. The arguments are now
3741 taken in correct order and client does not crash. The affected
3742 file is irssi/src/silc/core/silc-channels.c.
3744 Removed the "Inviting xxx to channel" message from the
3745 client library away and let the application handle it.
3746 Affected file lib/silcclient/command.c. Added that message
3747 to Irssi SILC client's message formats.
3749 * Fixed CMODE command crash in client. It now checks the
3750 amount of arguments correctly and does not crash. The affected
3751 file is lib/silcclient/command.c.
3753 * Do not create new channel automatically in silc_channels_join
3754 but check whether the channel by that name already exists.
3755 Affected file irssi/silc/core/silc-channels.c.
3757 * Do not send the SERVER_SIGNOFF to router if the disconnected
3758 entity was the router. Affected file silcd/server.c.
3760 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3761 SILC client as it was missing from there.
3763 Added the handling of the KICK notify to the Irssi SILC client
3764 as it was missing. Added "you have been kicked" message to
3765 Irssi SILC client's message modules formats.
3767 Added the handing of the KILL notify to the Irssi SILC client
3768 as it was missing. Added the kill message module formats
3771 The affected file is irssi/src/silc/core/silc-channels.c.
3773 * The router did not save the channel mode the server announced.
3774 Affected file silcd/packet_receive.c.
3776 * Fixed a possible crash in INFO command in server. If the
3777 server did not provide the server info it crashed. Affected
3778 file silcd/command.c.
3780 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Fixed the GETKEY command in the server to check also the
3783 global list. Otherwise the GETKEY would not work correctly
3784 in normal SILC server. Affected file silcd/command.c.
3786 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Fixed GETKEY crash, it crashed if the command did not succseed.
3790 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3793 is now real and not just an macro interface to GMP.
3795 Removed the entire GMP from the source tree and imported new
3796 NSS MPI library instead. Reason for removing GMP is that it is
3797 extremely large and compiles extremely slow. The NSS MPI
3798 is only a few files and compiles in less than 10 seconds.
3799 The speed is also about the same as GMP. The MPI is imported
3800 to lib/silcmath/mpi.
3802 If the system has GMP installed we will still use the GMP.
3803 If it is not then the NSS MPI will be compiled.
3805 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Merged a long nickname (127 characters long) crash bugfix from
3808 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3810 * Merged a freed memory reference bugfix from Irssi CVS tree.
3811 Affected file irssi/src/core/commands.c.
3813 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added the server's public key sving and verification to the
3816 server when performing the SKE. This was missing and the
3817 remote server's (or router's) public key was accepted without
3818 checking whether we have it previously or trust it at all.
3819 Affected file silcd/protocol.c.
3821 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Check in the silc_server_timeout_remote if protocol is active
3824 and make sure that the protocol's final callback is called so
3825 that all memory if freed. Affected file silcd/server.c.
3827 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * silc_server_whois_send_reply crashed the server if the nickname
3830 was 127 characters long. Affected file silcd/command.c.
3832 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Added sanity check to the silc_server_new_client. If the hostname
3835 is provided inside username then check that the provided hostname
3836 really is the same as the resolved one. If the hostname was not
3837 resolved then check it from the public key. Affected file is
3838 silcd/packet_receive.c.
3840 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3841 if the server disconnected us and the connection is not valid
3842 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3844 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3845 the library to the lib/silcutil/silcutil.[ch].
3847 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Close log file after open. Affected file
3850 lib/silcutil/silclog.c.
3852 * Check whether sock == NULL in silc_client_send_packet and return
3853 if it is. Affected file lib/silcclient/silcclient.c.
3855 * Check rec->entry == NULL in the Irssi SILC Client before
3856 sending the channel message. Affecte file is
3857 irssi/src/silc/core/silc-servers.c.
3859 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Merged a splitted window bugfix from Irssi CVS tree. The
3862 affected file is irssi/src/fe-text/textbuffer-view.c.
3864 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3865 It did not print nickname.
3867 * Improved the distributions system a bit.
3869 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3872 irssi/src/fe-text/gui-window.c.
3874 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3875 to in-active server. The affected file is
3876 irssi/src/silc/core/client_ops.c.
3878 * Resolve the client in USERS command reply if the entry does
3879 not have username resolved. The affected file is
3880 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3881 command to WHOIS command to really resolve stuff. The USERS
3882 is not used any more in any critical section so WHOIS can
3883 be used even though it might be slower than IDENTIFY.
3885 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3888 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Changed the protocol API a bit more consistent in the
3891 lib/silccore/silcprotocol.[ch].
3893 * Changed the following headers to ROBODoc format:
3895 lib/silccore/silcpayload.h
3896 lib/silccore/silcprotocol.h
3897 lib/silccore/silcsockconn.h
3899 All core library headers are now formatted.
3901 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Fixed a bug in Irssi SILC client; do not show that you are
3904 server/router operator if you really are not. Affected file is
3905 irssi/src/silc/core/client_ops.c.
3907 * Renamed silc_command_free_payload to silc_command_payload_free.
3908 Affected file lib/silccore/silccommand.h
3910 * Added silcmath.h to include the prototoypes of various routines
3911 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3914 * Changed the following headers to ROBODoc format:
3916 lib/silccore/silcchannel.h
3917 lib/silccore/silccommand.h
3918 lib/silccore/silcid.h
3919 lib/silccore/silcidcache.h
3920 lib/silccore/silcmode.h
3921 lib/silccore/silcnotify.h
3922 lib/silccore/silcpacket.h
3923 lib/silcmath/silcmath.h
3925 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Added checking to the server code not to start the server if
3928 ciphers and stuff are not configured properly. Affected files
3929 silcd/serverconfig.[h] and silcd/server.c.
3931 * Changed the layout of the header files of the public interfaces
3932 in the SILC libraries. The new layout supports ROBODoc
3933 documentation tool (and some others) so that it is easy to create
3934 a library reference manual. All the other headers and source
3935 code must still follow the CodingStyle document. Also source
3936 code must not include these ROBODoc stuffs, only the headers.
3937 Furthermore, all public interface headers must now be named
3938 by using `silc' prefix, example: silcapi.h, silccipher.h.
3939 Some files were renamed due to this. All the other headers
3940 must not be used as public interfaces. I will update the
3941 CodingStyle document later. Changed following headers, so far:
3943 lib/silcclient/silcapi.h
3944 lib/silccore/silcauth.h
3945 lib/silccore/silcprivate.h
3946 lib/silccrypt/silcdh.h
3948 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Removed silc_client_packet_send_flush from the client library
3953 as it is not needed. Affected file lib/silcclient/client.[ch].
3955 * Added printing of message of unresolved authentication method
3956 to the Irssi SILC client. Added it to the module formats.
3957 Removed the same message from the client library.
3959 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Added new distribution feature, DISTLABEL. Every distribution
3962 can define own preprocessor label that can be used in the
3963 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3964 file distributions, acconfig.h.pre and prepare.
3966 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Added Makefile.defines_int to include the actual definitions
3969 for Makefile.defines.in. Tested the new distribution system,
3970 created distributions and tested installation.
3972 * Added AWAY message printing to the Irssi SILC client. Added
3973 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3975 * Added SCONNECT command to call the SILC's CONNECT command.
3976 Cannot use CONNECT directly since Irssi uses that internally.
3977 Affected file irssi/src/silc/core/silc-servers.c.
3979 Added ACTION local command. It is same as ME command but takes
3980 the channel as mandatory argument.
3982 Rewrote some of the Irssi's help files to suite for SILC
3985 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Added Makefile.defines[.in] that should for now on be included
3988 in all Makefile.am file in the source tree. That file includes
3989 all common compilation definitions for SILC source tree.
3991 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Minor changes to the ./prepare script to change the package
3994 name according the distribution name to the configure.in.
3996 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Created new distribution system. Added file `distributions'
3999 that defines all the distributions that can be created out of
4000 the SILC source tree. The ./prepare script now reads that
4001 file to determine how to prepare the distributions. The
4002 first argument to the ./prepare is the name of the distribution
4003 and second is the version of the distribution. If given
4004 without arguments it creates the default (toolkit) distribution
4005 with the default version (defined in ./prepare).
4007 All Makefile.am files that are subject to the distributions
4008 are now named as Makefile.am.pre. These are ./Makefile.am
4009 and lib/Makefile.am. Others may be changed later.
4011 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Added invite list, ban list, some key management and connection
4014 error message printing to module formats in the Irssi SILC client.
4016 * Added new silc_client_set_away_message to set the away message
4017 that is back to the person who sent private message. The
4018 affected file lib/silcclient/silcapi.h and the
4019 lib/silcclient/client_prvmsg.c.
4021 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Fixed the private message sending in the Irssi SILC client,
4024 added local command KEY to the Irssi SILC client.
4026 Added key management and key agreement message formats to the
4027 irssi/src/fe-common/silc/module-formats.[ch].
4029 Added USERS (alias WHO) printing, server/router operator
4030 indication and LIST command printing to the module formats.
4032 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Fixed channel joining notify handling, cumode notify handling
4035 from Irssi SILC client.
4037 * Added SILC specific module-formats to the Irssi SILC client so
4038 that SILC specific message hilighting, colors etc is possible.
4039 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4041 Added channel mode, channel user mode, actions, notices,
4042 whois and whowas printing to the the module-formats.c.
4044 * Fixed a bug in channel deletion in the server. The channel
4045 is not left to the cache even if the channel founder auth mode
4046 is set when there are no users anymore on the channel. Affected
4047 file silcd/server.c.
4049 * The silc_net_localhost now resolves the entire hostname including
4050 the domain name. Affected file lib/silcutil/silcnet.c.
4052 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Changed the ask_passphrase client operation to be ascynchronous.
4055 It has now a completion callback and a context that the
4056 application must call after it has got the passphrase from
4057 the user. Affected files lib/silcclient/silcapi.h,
4058 lib/silcclient/protocol.c, lib/silcclient/command.c and
4061 Added SilcAskPassphrase callback that the application calls
4062 to deliver the passphrase to the library.
4064 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4065 The public key verification and especially a certificate
4066 verification is asynchronous procedure.
4068 Added new SILC_SKE_STATUS_PENDING status to indicate the
4069 request is pending and a callback will be called to finalize
4072 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4073 indicate that remote end did not send its public key (or
4074 certificate), even though we require it. Added check for this
4075 condition in the SKE. This was a security bug, now fixed.
4077 Defined new SilcSKEVerifyCbCompletion callback that is called
4078 when the verification process is completed.
4080 The affected files lib/silcske/silcske_status.h and
4081 lib/silcske/silcske.[ch].
4083 * Changed the verify_public_key client operation to be async
4084 as well. Defined SilcVerifyPublicKey callback that is used to
4085 indicate the success of the public key verification process.
4087 Changed the server and client to use the new async client
4090 * Changed the Irssi SILC client's internal scheduler to be called
4091 twice as many times as it used to be. As a result the client
4092 should be a bit faster now. Affected file is
4093 irssi/src/silc/core/silc-core.c.
4095 * Added support to Irssi SILC client of asynchronous public key
4096 verification and passphrase inquiry. Affected file is
4097 irssi/src/silc/core/silc-core.c.
4099 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Do not say "You have left channel %s" in client library.
4102 Moved it to the application. Affected files are
4103 lib/silcclient/command.c and silc/client_ops.c.
4105 * Fixed silc_client_get_clients. Command context was not
4106 duplicated and was freed memory in the callback. Affected
4107 file lib/silcclient/idlist.c.
4109 * Do not say "you are now talking..." on JOIN command in the
4110 client library. The appliation must handle it.
4112 * Do not say ".. changed topic to" in command reply in the
4113 client libary. The application must handle it.
4115 * Fixed TOPIC command sending in the client library.
4117 * Fixed a memory leak in silc_client_command_free in the file
4118 lib/silcclient/command.c.
4120 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Imported a modified version of Irssi client to the source tree.
4123 The Irssi will be used to create a new client called
4124 Irssi SILC. Imported to irssi/.
4126 Added silc_core_init_finish function to the Irssi. Affected
4127 file irssi/configure.in.
4129 A lot changes in the Makefile.ams around the irssi tree.
4131 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Do not rehash if the new size is same as the old size of the
4134 hash table, in the silc_hash_table_rehash*. The affected file
4135 lib/silcutil/silchashtable.c.
4137 * Replaced hash_table_del_by_context calls from the server
4138 (when channel->user_list and client->channels) to the
4139 hash_table_del as it is sufficient and faster.
4141 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Added silc_hash_table_list, silc_hash_table_get and the
4144 SilcHashTableList structure to provide an alternative way to
4145 traverse the hash table. The affected files are
4146 lib/silcutil/silchashtable.[ch].
4148 * Changed the server's idlist routines to use the hash table
4149 routines to optimize the code.
4151 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Replaced the client entry's `channel' list and channel entry's
4154 `user_list' list to hash tables for optimized lookup. Changed
4155 the code to use the hash table interface around the code.
4156 Affected file lib/silcd/idlist.[ch].
4158 * Added `auto_rehash' boolean argument to the function
4159 silc_hash_table_alloc to indicate whether the hash table should
4160 auto-rehash when it thinks is appropriate time. It will
4161 increase the hash table size if the there is twice as much
4162 entries in the table than the size of the table, and will
4163 decrease the size if there are twice as less entries than
4164 the size of the table.
4166 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4170 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * silc_idcache_purge_by_context deletes the entry now by context
4173 as it is supposed to do. Affected file lib/silccore/idcache.c.
4175 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4176 client is not anymore valid (WHOWAS givens the info) and not
4177 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4179 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Removed the `data' and `data_len' arguments from the ID Cache
4182 interfaces and added `name' argument. ID Cache does not handle
4183 anymore the binary data only a names associated with given ID.
4185 * When hashing a Client ID with silc_hash_id the entire ID is
4186 not hashed anymore, instead only the hash of the Client ID is
4187 hashed. This way we can access the Client ID from the cache
4188 with Client ID but with the hash of the ID (which is a hash of
4189 the nickname) as well without any difference in performance.
4191 Added also silc_idcache_find_by_id_one_ext to do one on one
4192 searching when we have the actual ID. Added also function
4193 silc_hash_client_id_compare. The affected files are
4194 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4196 * When hashing the name associated with a ID it is always done
4197 in lowercase. This way we can access the cache without worrying
4198 about case-sensitivity, even though, for example nicknames are
4201 * Fixed a bug in server with channel message sending. It put
4202 wrong ID type as destination ID. The affected file
4203 silcd/packet_send.c.
4205 * silc_idcache_del_by_context now deletes from all hash tables
4206 by context. Affected file lib/silccore/idcache.c.
4208 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Changed the client library to use the new ID Cache interface.
4211 Changes around the source tree.
4213 * Added silc_hash_table_rehash_ext to rehash with specific
4214 hash function. Affected file lib/silcutil/silchashtable.[ch].
4216 * Added silc_hash_string_compare to compare two strings in the
4217 hash table. Affected file lib/silcutil/silcutil.[ch].
4219 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Added new function silc_idcache_del_by_context into the
4222 lib/silccore/idcache.[ch].
4224 * Changed the server's ID list routines to use the new ID Cache
4225 interface. Changes around the source tree.
4227 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Added silc_hash_table_del[_by_context]_ext functions in to the
4230 lib/silcutil/silchashtable.[ch].
4232 Removed silc_hash_table_find_all* routines and added new
4233 silc_hash_table_find_foreach to replace them.
4235 Added silc_hash_table_replace_ext function as extended
4236 replacing function. Separated the simple hash table interface
4237 from the extended hash table interface in the file
4238 lib/silcutil/silchashtable.h.
4240 * Fixed minor bugs and changed it to use some of the new
4241 hash table functions in lib/silccore/idcache.c
4243 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Added new function silc_hash_table_find_all to return all keys
4246 in the hash table by the specified key. As the hash table is
4247 collision resistant it also makes it possible to have several
4248 duplicate keys in the hash table. This function may be used to
4249 find all of the keys from the hash.
4251 Added user_context arguments to the SilcHashFunction,
4252 SilcHashCompare and SilcHashDestructor to deliver user specified
4255 Added new fuctions silc_hash_table_find[_all]_ext to do
4256 extended lookup with specified hash and compare functions and
4257 specified user contexts.
4259 Added new function silc_hash_table_add_ext to add the key
4260 with specified hash function and user context.
4262 Added new function silc_hash_table_foreach to traverse all
4263 entrys in the hash table. Added SilcHashForeach callback
4266 Added new function silc_hash_table_del_by_context to delete
4267 the entry only if the context associated with the key matches.
4269 Affected files are lib/silcutil/silchashtable.[ch].
4271 * Removed silc_hash_[server/client/channel]_id and added just
4272 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4273 silc_hash_id_compare to compare two ID's using as the hash table
4274 comparison function. Added also silc_hash_data to hash
4275 binary data and silc_hash_data_compare to compare it.
4277 * Removed silc_idlist_find_client_by_hash as it is not needed
4278 anymore. Affected file silcd/idlist.[ch].
4280 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4281 to use internally the SilcHashTable. The new ID Cache is a lot
4282 faster than the old one. Some of the ID Cache interface was also
4283 rewritten and obsolete and stupid functions were removed.
4285 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Added entry_count field to the SilcHashTable to keep the number
4288 of the entries in the table. Implemented the function
4289 silc_hash_table_rehash. Added new function
4290 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4292 Fixed a minor bug in silc_hash_table_free.
4294 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4295 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4296 into the lib/silcutil/silcutil.[ch].
4298 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Implemented a collision resistant hash table into the
4301 lib/silcutil/silchashtable[ch]. See the header and the source
4302 for the SilcHashTable API.
4304 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Merged dotconf version 1.0.2 into lib/dotconf.
4308 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Do not compile anything in lib/silcsim/* if the SIM support
4311 is not enabled. The tree should now compile without problems
4314 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Compiled the SILC under cygwin. Compiled and tested briefly
4317 without problems. More tests needed. The SIMs didn't compile
4320 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4322 * Fixed possible crash in silc_get_username in the
4323 lib/silcutil/silcutil.c.
4325 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Fixed a va_arg in silc/client_ops.c.
4329 * Oops, RC5 routines were named AES and caused some problems
4330 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4332 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Added new SilcIDIP structure into the lib/silccore/id.h and
4335 replaced the old `ip' fields from all SILC ID's to that type.
4336 This is a step towards IPv6 support.
4338 The silc_id_get_len takes now the ID as an extra argument.
4339 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4340 both IPv4 and IPv6 based ID's.
4342 The affected files are lib/silccore/id.[ch] and other files
4343 around the tree using these routines.
4345 * Removed the ID length arguments in server from various
4346 silc_server_send_notify_* routines -> they are not needed
4349 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Fixed memory leak in silc_encode_pem_file in the file
4352 lib/silcutil/silcutil.c.
4354 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Check minor version as well in the SKE. Affected files are
4357 silcd/protocol.c and lib/silcclient/protocol.c.
4359 * Added --identifier option to the server so that an identifier
4360 can be when creating the public key for the server. Affected
4361 file is silcd/silcd.c.
4363 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4364 lib/silccrypt/silcpkcs.c.
4366 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Register default ciphers and stuff when using -C option with
4369 the server. Affected file sildc/silcd.c.
4371 * Put back the servers public key filename format, it is better
4372 than the new one. For now, the client keys are saved with the
4373 new filename format. The affected file silc/client_ops.c.
4375 * Implemented the Cipher API for the rest of the ciphers that
4376 did not implement it or implemented it the wrong way.
4378 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Register default ciphers and stuff when using the -S option
4381 in the client. Affected file silc/silc.c. Same also when
4382 creating new key pair with -C option.
4384 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Fixed the silc_verify_public_key client operation function to
4387 save the public keys differently. The fingerprint is now
4388 used as filename and not the hostname. This way also the
4389 client keys are saved uniquely and not with hostnames. The
4390 affected file is silc/client_ops.c.
4392 * Trimmed the silc_hash_fingerprint function to remove extra
4393 whitespaces from the end of the fingerprint. The affected
4394 file is lib/silccrypt/silchash.c.
4398 * Added silc_cipher_register_default function to register all
4399 default ciphers. It can be used when configuration files
4400 does not exist and the application does not want any specific
4401 ciphers in any specific order.
4403 The SilcDList is now used as silc_cipher_list dynamically
4404 allocated cipher list. Removed the static list all together
4405 and now all ciphers must be allocated to the dynamic list.
4406 The silc_cipher_alloc routine was changed to check only the
4409 All silc_cipher_* routines that used to return int returns
4412 The affected files lib/silccrypt/silccrypt.[ch].
4414 * The same thing was done to silc_hash_* as for silc_cipher_*
4415 routines. Affected files lib/silccrypt/silchash.[ch].
4417 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4418 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4419 Added also silc_pkcs_[un]register[_default] functions.
4420 Removed the data_context from the PKCS API.
4422 * Added silc_hmac_register_default function to register default
4423 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4424 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4425 to unregister all hmacs at once.
4427 * Register the default ciphers, hash functions, PKCSs and HMACs
4428 if client's configuration file does not exist. The affected
4431 * The client did not load the hash functions from the SIM
4432 modules at all. Added support for this. Affected file is
4433 silc/clientconfig.c.
4435 * When decoding public key with silc_pkcs_public_key_decode, check
4436 the supported algorithm only if PKCS are registered. Affected
4437 file lib/silccrypt/silcpkcs.c. The same was done with the
4438 silc_pkcs_private_key_decode.
4440 * Fixed the SILC List routines to keep the list always in order.
4441 It used to change the list's order when traversing the list but
4442 not it preserves the order. Affected file lib/trq/silclist.h.
4444 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Added the client library to use the SilcSocketConnection's
4447 reference counter (by silc_socket_dup) to prevent the bug that
4448 the socket object may be freed underneath async operation.
4450 * The name resolv library checking fixes in the configure.in.pre.
4453 * Created new version of the protocol drafts for future
4454 development. The -03 drafts are the ones that will be changed
4455 in the trunk now and the -02 will remain as they are.
4457 * Send list of CUMODE notifys to the router when announcing
4458 the channel users to the router. Affected file silcd/server.c.
4459 If the router receiving channel founder CUMODE for a channel
4460 that already has channel founder it will send CUMODE notify
4461 to the sender to remove the channel founder rights from the
4462 announced client. Affected file silcd/packet_receive.c.
4464 * The CUMODE notify may now use Server ID as well as the entity
4465 who changes the mode. Updated protocool specs.
4467 * Updated INSTALL and README files.
4469 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * New web pages in the http://silc.pspt.fi. The pages was
4476 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Implemented the [DenyConnectin] config section in the server.
4479 Added silc_server_config_denied_conn to check whether incoming
4480 connection is denied. Affected file silcd/serverconfig.[ch].
4482 * Do not check the ports when checking the incoming configuration
4483 data if the port is 0, meaning any. Affected file is
4484 silcd/serverconfig.c.
4486 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4488 * Fixed buffer overflow in silc_string_compare in the file
4489 lib/silcutil/silcutil.c.
4491 * Fixed double free in silc_server_command_leave in the file
4494 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Fixed the version checking in the server. Affected file is
4499 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Fixed the configuration data fetching when accepting new
4502 connections in the server. Affected file silcd/server.c.
4504 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Added `sender_entry' argument to the function
4507 silc_server_packet_relay_to_channel so that we can check
4508 whether some destination actually belongs to the same route
4509 the sender belongs (ie, we must not resend the packet to the
4510 sender). Affected file silcd/packet_send.[ch].
4512 * Added `servername' field to the SilcClientEntry in the server
4513 to hold the name of the server where client is from. Affected
4514 file is silcd/idlist.h.
4516 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Moved the channel message encrypting in the router betwen
4519 router connections from silc_server_channel_message to the
4520 silc_server_packet_relay_to_channel since we want to check
4521 whether we have anybody channel before encrypting anything.
4522 Affected files silcd/packet_[receive/send].c.
4524 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Fixed the [AdminConnection] server config section to support
4527 multiple entries. Affected file silcd/serverconfig.c.
4529 * Added support into the server to check the validity of the
4530 incoming connection before executing any KE or authentication
4533 * The connection configuration is now saved to the KE and
4534 connection auth protocol contexts and not fetched anymore in
4535 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4537 * The local hosts listenning address and port is also resolved
4538 now when starting the server. We want to have the socket object
4539 to include the real address and port for the listener. Added
4540 new function silc_net_check_local_by_sock into the files
4541 lib/silcutil/silcnet.[ch].
4543 * Fixed a broadcast bug in server -> do not broadcast if we
4546 * Fixed a routing bug. Do not route broadcast packets ever.
4547 Broadcast packets must be processed always and not routed since
4548 they may be destined to some other host than yourself and thus
4549 would get routed without no good reason. Affected file is
4552 * Added function silc_server_config_is_primary_route to check
4553 whether primary router connection has been configured (a router
4554 configuration that we are initiating). If there is not, we
4555 will assume that there is only two routers in the SILC network
4556 and we will use the incoming router connection as our primary
4557 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4559 * Changed the order of the broadcasting. Broadcast _after_ the
4560 packet has been processed not before. Affected file is
4563 * Fixed a [ClientConnection] parsing bug. The port was never
4564 parsed correctly thus resulting to port 0. Affected file
4565 silcd/serverconfig.c.
4567 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4568 argument and did not set the broadcast packet flag. Affected
4569 file silcd/packet_send.c. Fixed same bug in the function
4570 silc_server_send_notify as well.
4572 * If we receive NEW_ID packet for our own ID in the server, ignore
4575 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Removed the nickname from the Private Message Payload.
4580 Updated the code and the protocol specs.
4582 * Updated protocol specs for submitting to the IETF.
4584 * Tweaked the Random Number Generator a bit. Affected file
4585 lib/silccrypt/silcrng.c. Exported a new function
4586 silc_rng_[global]_add_noise which can be used to add more
4589 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Do not parse packets with different timeout when protocol
4592 is active -> may cause problem with rekey. Affected file
4595 * When server receives signoff notify it must not create
4596 new channel key if the client is on any channels since the
4597 sender of the signoff notify will create it.
4599 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Added printing of error messages during SKE protocol from the
4602 failure packet sent by server during SKE. Affected file
4605 * Removed the client's failure_callback handling with timeout
4606 and handle it immediately when received.
4608 * The SKE library returned wrong type in SUCCESS and FAILURE
4609 packets. They must be 32 bit MSB not 16 bit MSB.
4611 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Ok, rewrote the logic of the re-key and now it seems to work.
4614 I tested it on high traffic with frequent re-keys without
4615 problems. Added hmac_receive (and renamed hmac to hmac_send)
4616 in SilcClientConnection in lib/silcclient/client.h and
4617 in SilcIDListData in silcd/idlist.h. Also, removed the
4618 SilcPacketParserContext's cipher and hmac fields as they are
4619 not needed anymore and actually caused some problems when
4620 the ciphers and hmac's changed underneath the packet parser.
4622 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * If re-key protocol is active then process the incoming packets
4625 synchronously since we must assure that icoming packets encrypted
4626 with the old key is processed before the new keys is set to
4627 use. This is true other packets than for REKEY packets.
4628 Affected file silcd/server.c. The same was done to client library
4629 as well, affected file lib/silcclient/client.c.
4631 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Fixed bug in client and server to accept the force send if
4634 the packet is send from silc_[server/client]_packet_process
4635 function. Otherwise the packets are never delivered, oops.
4637 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Disable force sending of packets when REKEY protocol is active.
4640 We must assure that no packet is sent directly when rekey is
4641 performed. All packets must be sent through packet queue.
4642 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4643 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4644 function is silc_[server/client]_packet_send_real to check
4647 * Replaced the SIM paths from example config files to
4648 /usr/local/modules. Also, make install creates now
4649 /usr/local/silc/logs directory to hold all the SILC server
4652 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Made the configure.in.pre work on Solaris. Patch by salo.
4656 * Made all ciphers compatible with non-x86 machines. Defined
4657 CBC mode macros into lib/silccrypt/ciphers_def.h.
4659 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Fixed the make install.
4663 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * When MAC computation fails the silc_packet_decrypt returned 0
4666 even though it was supposed to return -1. Fixed this. The
4667 affected file is lib/silccore/silcpacket.c.
4669 * Do not replace the config files in /etc/silc (in make install)
4670 if they already exist. Affected file ./Makefile.am.
4672 * Do not send re-key packets immediately but through packet queue.
4673 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4675 * Changed silc_net_check_host_by_sock to return FALSE if the
4676 IP/DNS could not be resolved. Though, it returns the IP address
4677 now even if it could not resolve it (but returns also FALSE).
4678 Affected file lib/silcutil/silcnet.[ch].
4680 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Added silc_pkcs_decode_identifier to decode the public key's
4683 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4684 Added also silc_pkcs_free_identifier. Added also new context
4685 SilcPublicKeyIdentifier.
4687 * Added -S option to the silc client. It is used to dump the
4688 contents of the specified public key file.
4690 * Changed the PKCS api to return the public key length when
4691 setting the public key.
4693 * Fixed a fatal bug in the public and private key file loading.
4694 Affected file lib/silccrypt/silcpkcs.c.
4696 * Execute the packet parsing for client with zero (0) timeout
4697 if the protocol is active. Affected file silcd/server.c.
4699 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Made the key generation options to the silcd program. Added
4702 -C option, equivalent to client's option.
4704 * Added new [ServerKeys] config section to the server. It
4705 configures the server's public and private key.
4707 * Defined generic Public Key Payload into the protocol
4708 specification to send specific type of public keys and
4711 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4712 public key or certificate.
4714 * Implemented the GETKEY command to the server and to the
4715 client library and on user interface.
4717 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Made preliminary `make install' work.
4721 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Added SilcServerRekey context into silcd/idlist.h.
4725 * Added the PFS support as defined in the specification to the
4726 SKE protocol. Affected files lib/silcske/*.c.
4728 * Added `ske_group' field to the SilcServerRekey context to hold
4729 the number of the SKE group that is used with PFS in re-key.
4730 Affected file silcd/idlist.h.
4732 * Added PFS re-key support to the server. Affected file is
4735 * Added silc_protocol_cancel to cancel execution of the next
4736 state of the protocol. Affected file is
4737 lib/silccore/silcprotocol.[ch].
4739 * Added the re-key support with and without PFS to the client
4740 library. Re-key is performed once in an hour, by default.
4742 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4743 Added silc_client_rekey_callback and silc_client_rekey_final.
4744 Affected files are lib/silcclient/protocol.[ch] and
4745 lib/silcclient/client.[ch].
4747 * Removed the `hmac_key' and `hmac_key_len' fields from the
4748 SilcClientConnection structure; not needed. Affected file is
4749 lib/silcclient/client.h.
4753 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Do not ask whether user wants to use the negotiated private key
4756 for private messages, just use it. Affected file is
4757 silc/local_command.c.
4759 * Added `send_enc_key' and `enc_key_len' fields to the
4760 SilcIDListData structure since they are needed in the re-key
4761 phase. Affected file is silcd/idlist.[ch].
4763 * Implemented the simple re-key protocol into the server.
4764 Affected files silcd/server.c and silcd/protocol.[ch]. The
4765 re-key will be performed once in an hour, by default.
4767 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4768 Added silc_server_rekey, silc_server_rekey_callback and
4769 silc_server_rekey_final.
4771 * Removed Tunneled flag from the protocol. Updated the code
4772 and the specifications.
4774 * Adde `pfs' field to the SilcIDListData to indicate whether
4775 the PFS is to be performed in the re-key. Affected file is
4778 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4781 int64 of at least the xintXX size. If void * is less that 4
4782 bytes uint32 * will be used. Defined bool as boolean.
4784 * Changed _ALL_ unsigned long and unsigned int to uint32,
4785 unsgined short to uint16 in the source tree.
4787 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4788 not handle clients that has entry->data.registered == FALSE.
4789 They are not in the network anymore. Affected file is
4792 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Implemented the sending of the SERVER_SIGNOFF notify in the
4795 server. Affected file is silcd/server.c.
4797 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4798 Added also silc_notify_payload_encode_args into the
4799 lib/silccore/silcnotify.[ch].
4801 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4802 Affected file silcd/packet_receive.c.
4804 * Implemented the SERVER_SIGNOFF notify handling in the client
4805 library. Affected file lib/silcclient/client_notify.c. Also,
4806 implemnted the printing of the SERVER_SIGNOFF info to the
4807 application. Affected file silc/client_ops.c.
4809 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4810 if the deleting was successful. Affected file silcd/idlist.[ch].
4812 * Added support for public key authentication in the connection
4813 authentication protocol in the client library. Affected file
4814 lib/silcclient/protocol.c.
4816 * Changed the server's silc_idlist_get_clients_by_* interface
4817 to support already allocated array so that new entries may be
4818 added to pre-allocated array. Affected file silcd/idlist.[ch].
4819 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4820 and command replies.
4822 * All command reply functions in the server now calls the
4823 pending command callback even if error occured. This way the
4824 error will be delivered to the client as well. Affected files
4825 silcd/command.c and silcd/command_reply.c.
4827 * Fixed INFO command to return local server's info if no server
4828 was provided. Affected file lib/silcclient/command.c.
4830 * Removed RESTART command for good. Updated the code and the
4833 * Rewrote parts of the task system. It is a bit simpler now.
4834 Removed unsued task priorities. The affected files are
4835 lib/silcutil/silctask.[ch].
4837 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Moved the USERS printing from the library to the application.
4840 Affected files lib/silcclient/command.c and silc/client_ops.c.
4842 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added channel key re-key support. The re-key is perfomed
4847 only by the router and is done once in an hour. Added `rekey'
4848 field to the SilcChannelEntry in the server. Affected files
4849 silcd/server.c and silcd/idlist.h.
4851 * Added silc_task_unregister_by_context into the file
4852 lib/silcutil/silctask.[ch].
4854 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Added SILC_UMODE_GONE mode to indicate when the client is not
4857 present in the SILC network. Added also support to the local
4858 command AWAY that will set this mode. Added support of showing
4859 "xxx is gone" in WHOIS command. The USERS command shows the
4860 gone status as well.
4862 * Fixed setting server and router operator privileges in the
4863 server's UMODE command. Affected file silcd/command.c.
4865 * Merged the SKE KE1 and KE2 payloads into one payload. The
4866 new KE payload is equivalent to the old KE2 payload.
4868 Cleaned up the SKE Start Payload parsing. It now uses the
4869 simple buffer unformatting to do the parsing. A lot faster
4872 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4873 to the SKE that is used to indicate whether both of the SKE
4874 parties should perform authentication. By default only the
4875 responder performs authentication. By setting this flag also
4876 the initiator must do authentication. By default it is unset
4877 since in normal SKE case, client to server connection, only
4878 the responder should do authentication. When doing SKE between
4879 two clients both should perform authentication. Updated the
4880 code and the protocol specs.
4882 * A little fix to IDENTIFY command in the server. Search the
4883 client first by hash not nickname. Affected file is
4886 * Fixed the silc_client_close_connection to support closing
4887 the client to client connections wihtout deleting too much
4888 data. Affected file lib/silcclient/client.c.
4890 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4891 are received if protocol used to be active but is not anymore
4892 the application would crash due to NULL pointer dereference.
4893 Affected files silcd/server.c and lib/silcclient/client.c.
4895 * Added `hash' field to the SilcClientConnection to include
4896 the hash function negotiated in the SKE protocol.
4898 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4899 to set the channel founder authentication data. A client can
4900 claim the founder rights later by providing the authentication
4901 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4902 This way the channel founder can regain the channel founder
4903 privileges even it is left the channel. This works only on
4904 local server and the client must be connected to the same
4905 server to be able to regain the founder rights. Updated the
4906 protocol specs accordingly.
4908 Added support to the CMODE command in the client to set the
4909 founder auth data. Read the README to see how to set it.
4911 Added support to the CUMODE command to claim the founder
4912 rights. Read the README to see how to do it.
4914 Added support for the founder authentication to the Channel
4915 Entry in the server. Affected file silcd/idlist.h.
4917 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4918 server's CMODE command. Affected file silcd/command.c.
4920 * Added the following new functions into lib/silccore/silcauth.[ch]:
4921 silc_auth_get_method and silc_auth_get_data.
4923 * The server now saves the remote hosts public key to the
4924 SilcIDListData pointer. Affected file silcd/protocol.c.
4926 * The normal server now does not remove the channel entry from
4927 the cache if the founder authentication data is set. It used
4928 to remove it if the founder was the last one on the channel on
4929 the server and left the channel. The auth data is saved and
4930 if the channel is re-joined later the old entry is used with
4931 the old auth data. Affected files silcd/command_reply.c and
4934 * Removed the `pkcs' field from the SilcIDListData structure
4935 in the server; it is not used. Affected file silcd/idlist.h.
4937 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Fixed packet processing on slow links. Partial packets were
4940 never re-processed because the incoming data buffer was cleared
4941 by the application. Application must not directly clear the
4942 sock->inbuf, the packet processing routines handle it. Fixed
4943 this in client library and in server.
4945 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Fixed the WHOIS and IDENTIFY send reply function to really
4948 check whether to send list or just one entry. Affected file
4951 * Cleaned up the LEAVE command's channel key distribution. The
4952 affected file silcd/command.c.
4954 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4955 can enforce the channel mode as well. In that case the ID
4956 includes the ID of the server. The code now enforces the
4957 mode change if the router have different mode than the server.
4959 * The notify client operation with CMODE_CHANGE notify can now
4960 return NULL client_entry pointer if the CMODE was not changed
4961 by client. Application must check for this.
4963 * Added <Server ID> argument to INFO command to support server
4964 info fetching by Server ID.
4966 * Added silc_server_announce_get_channel_users to get assembled
4967 packets of channel users of the specified channel. Affected
4968 file silcd/server.[ch].
4970 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4971 was freed underneath the ID Cache.
4973 * Re-announce clients when the server received CHANNEL_CHANGE
4974 notify from the router. Affected file silcd/packet_send.c.
4976 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4979 crashed since it did not handle the fact that there is no cipher
4980 called "3" and didn't check the error condition. Now fixed.
4982 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4983 flag. It can be used to send message requests.
4985 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Implemented the RESTART command in the client.
4989 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4990 notice type messages. Added notice printing to the user
4993 * The channel keys are not re-generated if the channel's mode
4994 is PRIVKEY, ie private key on the channel exists. Affected
4995 files silcd/server.c and silcd/command.c.
4997 * Fixed a little bug in channel message delivery when channel
4998 private keys are set in the server. Affected file is
4999 silcd/packet_send.c.
5001 * Changed the setting on channel->on_channel = TRUE from the
5002 silc_client_save_channel_key to the JOIN command reply. The
5003 key payload is not received if the private channel key is set.
5004 Affected file lib/silcclient/command_reply.c and the
5005 lib/silcclient/client_channel.c.
5007 * When the CMODE_CHANGE notify is sent and the channel private
5008 key mode is removed the channel key must be re-generated in
5009 other cells as well. Added this support for the router in the
5010 silcd/packet_receive.c.
5012 * Added new local command NOTICE to send notice message on
5013 channel. Affected file silc/local_command.[ch].
5015 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Added new local command ME to the client. It is used to send
5018 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5019 some action. Affected file silc/local_command.[ch].
5021 * Changed channel_message and private_message client operations
5022 to deliver the message flags to the application. Added also
5023 the `flags' arguments to the silc_client_send_channel_message
5024 and silc_client_send_private_message functions. Affected file
5027 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Redefined the Private Message Payload to support private message
5030 keys and to support the new private message flags. Updated
5031 the protocol specs. Flags makes it possible to have for example
5032 CTCP style messages.
5034 * Added new type SilcPrivateMessagePayload and defined an API
5035 for it in the lib/silcclient/silcprivate.[ch].
5037 * Tested private message private keys successfully. Tested the
5038 private message key set, unset and list commands with the new
5041 * Redefined the Channel Message Payload to include the channel
5042 message flags (equal with private message flags) to support
5043 for example CTCP style messages.
5045 * Defined some of the message (for channel and private message)
5046 flags. Updated the protocol specs and added the flags to the
5047 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5049 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Added SilcKeyAgreementStatus type to the key agreement routines
5052 to indicate the current status and error if one occured.
5053 The status types are defined in the lib/silcclient/silcapi.h.
5055 * Added new local command KEY that is used to set and unset private
5056 keys for channels, set and unset private keys for private messages
5057 with remote clients and to send key agreement requests and
5058 negotiate the key agreement protocol with remote client. The
5059 key agreement is supported only to negotiate private message keys,
5060 it currently cannot be used to negotiate private keys for channels,
5061 as it is not convenient for that purpose.
5063 * Fixed a minor pending callback setting bug in the function
5064 silc_client_get_client_by_id_resolve, now the function works.
5065 Affected file lib/silcclient/idlist.c.
5067 * Added function silc_net_get_local_port to get local bound
5068 port by socket. Added to lib/silcutil/silcnet.[ch].
5070 * Added `sockets' and `sockets_count' fields to the SilcClient
5071 object. They hold the sockets of the listenning sockets in
5072 the client. Listenning sockets may be for example the key
5073 agreement server. Affected file lib/silcclient/client.[ch].
5074 Added functions the silc_client_add_socket and the
5075 silc_client_del_socket. They are exported to the application
5078 * Added ~./silc/clientkeys to support other client's public keys.
5080 * Renamed verify_server_key client operation to verify_public_key
5081 and added one argument to indicate the type of the connection
5082 (server, client etc.).
5084 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Added silc_server_connection_auth_request to handle the
5087 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5088 silcd/packet_receive.[ch].
5090 * Added silc_server_send_connection_auth_request into the
5091 silcd/packet_send.c to send the connection auth request packet.
5093 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5096 * Fixed the public key authentication in responder side in the
5097 server. The `auth_data' pointer includes the SilcPublicKey
5098 not the path to the public key. Affected file silcd/protocol.c.
5100 * Implemented the public key authentication in the initiator side
5101 in the server. Affected file silcd/protocol.c.
5103 * Removed the [RedirectClient] config section from the server
5104 configuration. Is not needed and I don't want to implement it.
5106 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Cleaned up the CMODE command in the server. It now works
5109 correctly and supports all the modes defined in the protocol.
5110 Affected file is silcd/command.c.
5112 * Added `hmac_name' field to the SilcChannelEntry in the server
5113 to hold the default HMAC of the channel. It can be set when
5114 creating the channel (with JOIN command). Affected files
5117 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5118 type to indicate the change of the current cipher and hmac
5119 on the channel. Client can safely ignore the <cipher> argument
5120 (if it chooses to do so) since the CHANNEL_KEY packet will
5121 force the channel key change anyway. The <hmac> argument is
5122 important since the client is responsible of setting the new
5123 HMAC and the hmac key into use.
5125 * Fixed the CMODE command in the client library as well.
5127 * Tested CMODE command in router environment successfully.
5129 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Show the version of the remote client (or server) when connecting
5132 to the server. It is logged to the log file. Affected file
5133 is silcd/protocol.c.
5135 * Fixed the KILLED notify handling in the client library. The
5136 client must be removed from all channels when receiving the
5139 Also, do not remove the client entry when giving the KILL
5140 command but when the KILLED notify is received.
5142 * Removed silc_idlist_find_client_by_nickname from the server.
5143 Not needed anymore. Affected files silcd/idlist.[ch].
5145 * Implemented the CHANNEL_CHANGE notify type handling to the
5146 server. Affected file silcd/server.c.
5150 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Added silc_server_send_notify_invite to send the INVITE
5153 notify between routers.
5155 * Implemented the INVITE command correctly to the server.
5157 * Implemented the INVITE notify type handling in the server.
5159 * Implemented the INVITE command to the client library and on the
5162 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Added function silc_server_get_client_resolve to find the
5165 client entry by ID from all ID lists and then resolve it
5166 (using WHOIS) if it cannot be found. Affected file is
5169 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Implemented the BAN command to the client library.
5173 * The JOIN command in the server now checks the invite list
5176 * Changed the silc_command_reply_payload_encode_va and the
5177 silc_command_payload_encode_va to support that if argument is
5178 NULL it ignores and checks the next argument. Affected file
5179 lib/silccore/silccommand.c.
5181 * Added silc_server_send_notify_ban to send the BAN notify
5182 type between routers.
5184 * Chaned the silc_notify_payload_encode to support that if
5185 argument is NULL it ignores and checks the next argument.
5186 Affected file lib/silccore/silcnotify.c.
5188 * Tested ban lists in router environment successfully.
5190 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Implemented BAN command to the server, in silcd/command.[ch].
5194 * Removed the BAN and INVITE_LIST modes from the CMODE command
5197 * Added function silc_string_match to regex match two strings.
5198 Affected files lib/silcutil/silcutil.[ch].
5200 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Redefined parts of the SilcChannelEntry in the server to support
5203 the new ban and invite lists.
5205 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Redefined the INVITE command. The same command can be used to
5208 invite individuals to the channel but also to manage the invite
5209 list of the channel (to add to and remove from the invite list).
5210 Updated the protocol specs.
5212 * Added new command SILC_COMMAND_BAN that can be used to manage
5213 the ban list of the channel. Updated the protocol specs.
5215 * Removed the channel modes: the SILC_CMODE_BAN and the
5216 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5217 in the CMODE command. The equivalent features are now available
5218 using INVITE and BAN commands. Updated the protocol specs.
5220 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5221 in the network about change in the current ban list. The notify
5222 type is not used by the client.
5224 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5225 support the invite lists.
5227 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Added new function silc_string_regexify that converts string
5230 including wildcard characters into regex string that can
5231 be used by the GNU regex library. Added into the file
5232 lib/silcutil/silcutil.[ch].
5234 Added silc_string_regex_combine to combine to regex strings
5235 into one so that they can be used as one regex string by
5236 the GNU regex library. Added into the file
5237 lib/silcutil/silcutil.[ch].
5239 Added silc_string_regex_match to match two strings. It returns
5240 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5242 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Imported GNU regex to the soruce tree into lib/contrib.
5245 Fixed some compiler warning from the regex.c.
5247 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Fixed MOTD command in the server to work in router environment.
5251 * Fixed the MOTD command in the client library to support
5252 the server argument in the command.
5254 * Added `nickname_len' argument to the silc_idlist_add_client
5255 in the server, as the `nickname' argument may be binary data
5258 * Added silc_idlist_get_channels to return all channels from
5261 * Implemented LIST command to the server. Affected file is
5264 * Implemented the LIST command to the client library and on the
5267 * Added [<user count>] argument to the LIST command reply.
5268 With private channels the user count is not shown.
5270 * Updated TODO and README.
5272 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * The client entry's data.registered must be TRUE even with
5275 global client entry on global client list. The data.registered
5276 is used to check whether the client is anymore in the network,
5277 for example with WHOWAS command so it must be valid.
5279 * Fixed the WHOWAS command in the server. It now actually works
5280 in router environment. Added function into silcd/command_reply.c
5281 silc_server_command_reply_whowas_save.
5283 * Added silc_idlist_purge function to the silcd/idlist.c
5284 to periodically purge the ID Cache.
5286 * Fixed INFO command in the server. It works now in router
5287 environment. Added <server name> argument to the INFO command
5288 reply. Updated the protocol specs.
5290 * Fixed minor bug in silc_idcache_purge to not purge if the
5291 expire value is zero.
5293 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5294 they were buggy because of the WHOWAS information.
5296 * Fixed local command MSG to handle the async resolving of
5297 the remote client properly. It used to fail the first MSG.
5298 Affected file silc/local_command.c.
5300 * Added `data_len' field to SilcIDCache context.
5302 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Update TODO. Todo in commands in the server.
5306 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5309 used by routers as broadcast packet to inform other routers
5310 about the changed user mode.
5312 Implemented the notify handling in the server. Affected file is
5313 silcd/packet_receive.c. Added the function
5314 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5316 * Added new generic Channel Payload and deprecated the New Channel
5317 Payload. The New Channel Payload is now the generic Channel
5320 * Added new argument `mode' to the silc_server_send_new_channel
5321 as it is required in the Channel Payload now.
5323 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5324 and created a new and real SilChannelPayload to represent the
5325 new generic Channel Payload. Implemented the encode/decode
5326 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5328 * Added silc_server_get_client_channel_list to return the list
5329 of channels the client has joined for WHOIS command reply.
5330 Affected file silcd/server.[ch].
5332 * Implemented the channel list sending in the WHOIS command reply
5333 in server and in the client.
5335 Implemented the channel list displaying on the user interface
5336 as well. Affected file silc/client_ops.c.
5338 * Added silc_channel_payload_parse_list to parse list of Channel
5339 Payloads. It returns SilcDList list of SilcChannelPayloads.
5340 Client for example can use this function to parse the list of
5341 channels it receives in the WHOIS command reply. The caller
5342 must free the list by calling silc_channel_payload_list_free.
5343 Affected files lib/silccore/silcchannel.[ch].
5345 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * Added one new argument <user mode> to the WHOIS command reply
5348 to return the mode of the user in SILC. Updated the protocol
5351 Implemented it to the server and client.
5353 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Fixed the mode printing on the user interface on joining.
5356 Affected file silc/client_ops.c.
5358 * Implemented the UMODE command and user modes in general to the
5359 client library and to the user interface.
5361 * Implemented the UMODE command to the server.
5363 * The server now sends UNKNOWN_COMMAND error status if client sends
5364 unknown command. Affected file silcd/command.c.
5366 * All server commands now handle the command identifier the right
5367 way when sending the command reply to the client. The client can
5368 use to identify the command replies with the identifier.
5370 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Added silc_server_get_client_route to resolve the route to
5373 the client indicated by the client ID. Affected file is
5376 * Added silc_server_relay_packet as general function to relay
5377 packet to arbitrary destination. This deprecates functions
5378 like _send_private_message_key, _relay_notify etc. Affected
5379 file is silcd/packet_send.[ch].
5381 Removed silc_server_send_key_agreement,
5382 silc_server_send_private_message_key and
5383 silc_server_packet_relay_notify functions from the file
5384 silcd/packet_send.[ch].
5388 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5389 server. Affected file silcd/packet_receive.[ch].
5391 * Implemented the KILL command to the client. Implemented the
5392 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5393 Affected files lib/silcclient/command[_reply].c and
5394 lib/silcclient/client_notify.c. Implemented the KILL notify
5395 printing in the user inteface.
5397 * Fixed a lot silc_parse_nick memory leaks from the client
5398 library in the file lib/silcclient/command.c.
5400 * Changed the silc_server_send_notify_on_channels's `sender'
5401 argument from SilcSocketConnection to SilcClientEntry to
5402 check the sender as entry and not as connection object and not
5403 to send to the client provided as argument. The affected file
5404 is silcd/packet_send.[ch].
5406 * The notify packets that are destined directly to the client used
5407 to not to be processed by the server. Now changed that and the
5408 server processes all notify packets. After relaying the packet
5409 to the client the notify packet is processed in the server.
5411 * The silc_server_free_client_data now checks whether there is
5412 pending outgoing traffic for the client and purges the data to
5413 the network before removing the client entry.
5415 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5418 an client is killed from the SILC Network. Updated the protocol
5421 Added new function silc_server_send_notify_killed to the
5422 silcd/packet_send.[ch].
5424 * Added function silc_server_packet_relay_notify to relay notify
5425 packets that are destined directly to a client. In this case
5426 the server does not process the notify packets but merely relays
5427 it to the client. Affected file silcd/packet_send.[ch].
5429 Added also silc_server_packet_process_relay_notify to check
5430 whereto relay the notify. Affected file is
5431 silcd/packet_receive.[ch].
5433 * Implemented the KILL command to the server.
5437 * Added the backup schema desgined last fall to the protocol
5438 specs for everyone to see. The specification is in the
5439 *-spec-xx.txt draft and the packet type definitions for the
5440 backup routers is in *-pp-xx.txt draft. Thusly, added also
5441 new packet type SILC_PACKET_CELL_ROUTERS.
5443 * A big security problem in the implementation discovered. The
5444 signoff of an client did not cause new channel key generation
5445 which it of course should've done. The channel keys must be
5446 always re-generated when client leaves (or signoffs) the channel.
5447 The silc_server_remove_from_channels funtion now handles
5448 the channel key re-generation.
5450 * Added `sender' argument to the silc_server_send_notify_on_channels
5451 to not to send the client provided as argument. Affected file
5452 silcd/packet_send.[ch].
5454 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Implemented OPER and SILCOPER commands into the server and
5459 * Added silc_auth_verify and silc_auth_verify_data to verify
5460 the authentication directly from the authentication payload.
5461 It supports verifying both passphrase and public key based
5462 authentication. Affected file lib/silccore/silcauth.[ch].
5464 * Added `hash' field to the SilcIDListData structure. It is the
5465 hash negotiated in the SKE protocol. Affected file is
5468 * Slight redesigning of the SilcAuthPayload handling routines.
5469 Do not send SilcPKCS but SilcPublicKey as argument.
5471 * Implemented the public key authentication support to the
5472 serverconfig. The public key is loaded from the provided path
5473 and saved as authentication data to void * pointer. Thus,
5474 changed the unsigned char *auth_data to void *auth_data;
5476 * Fixed SHUTDOWN command to send the reply before the server
5477 is shutdown. :) Affected file silcd/command.c.
5479 * Fixed fatal bug in CONNECT command. The hostname was invalid
5480 memory and server crashed. Affected file silcd/command.c.
5482 * Fixed fatal bug in CLOSE command. The server_entry became
5483 invalid but was referenced later in the command. Affected file
5486 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Fixed fatal bug in failure packet handling. Server ignored
5489 the failure and thus crashed when it came.
5493 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5496 that the command may be executed only once in (about) 2 seconds.
5497 The old SILC_CF_LAG flag is same but allows command bursts up
5498 to five before limiting.
5500 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5501 server code. Various commands now includes the CF_LAG_STRICT
5502 flag to disallow any kind of miss-use of the command.
5504 * Fixed the silc_buffer_unformat to not to allocate any data
5505 if the length of the data is zero. It used to allocate the
5506 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5508 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Changed the format of AdminConnection configuration section
5511 in the server. Added username of the admin to the format.
5512 Affected files silcd/serverconfig.[ch].
5514 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5515 to return admin configuration data by host, username and/or
5518 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Implemented WHOWAS command to the server. Added the functions:
5522 silc_server_command_whowas_parse,
5523 silc_server_command_whowas_send_reply,
5524 silc_server_command_whowas_from_client and
5525 silc_server_command_whowas_from_server
5527 * Added <Client ID> argument to the WHOWAS command reply. Updated
5528 the protocol specs accordingly.
5530 * Implemented WHOWAS command and command_reply to the client
5533 Implemented the WHOWAS printing on the user interface.
5535 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Added new argument to the WHOWAS command reply, the real name.
5538 It is an optional argument. Updated the protocol specs.
5540 * Added SilcIDCacheDestructor callback that is registered when
5541 the SilcIDCache is allocated. The callback is called when
5542 an cache entry in the ID Cache expires, or is purged from the
5543 cache. Added into lib/silccore/idcache.[ch].
5545 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5546 to destruct the client entries when the cache entry expires.
5547 Other ID Cache's in server and in the client library ignores
5550 * If the ID Cache entry's `expire' field is zero then the entry
5551 never expires. Added boolean `expire' argument to the
5552 silc_idcache_add function in the lib/silccore/idcache.[ch].
5553 If it is TRUE the default expiry value is used.
5555 * Added silc_server_free_client_data_timeout that is registered
5556 when client disconnects. By default for 5 minutes we preserve
5557 the client entry for history - for WHOWAS command.
5559 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Added support to the server to enforce that commands are not
5562 executed more than once in 2 seconds. If server receives
5563 commands from client more frequently, timeout is registered
5564 to process the commands. Affected file silcd/command.c.
5565 Added new function silc_server_command_process_timeout.
5567 * Changed NICK_NOTIFY handling in client library to check that
5568 if the client's nickname was changed, so there is no need to
5569 resolve anything from the server.
5571 * Removed error printing from the WHOIS and IDENTIFY commands.
5572 If error occurs then it is ignored silently in the client library.
5573 The application, however, may map the received error to
5574 human readable error string. The application currently maps
5575 the NO_SUCH_NICKNAME error to string.
5577 * Made the command status message public to the application. Moved
5578 them from lib/silcclient/command_reply.c to
5579 lib/silcclient/command_reply.h. The application can map the
5580 received command status to the string with the
5581 silc_client_command_status_message function.
5583 * Added check to the server to check that client's ID is same
5584 as the Source ID in the packet the client sent. They must
5587 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Added dist-bzip hook to the Makefile.am to make bzip2
5590 compressed distributions.
5592 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Server now enforces the maximum length for the nickname and
5595 the channel as protocol specification dictates. 128 bytes for
5596 nickname and 256 bytes for channel name.
5598 * Moved the WHOIS printing to the application. The client libary
5599 does not print out the WHOIS information anymore, the application
5600 must do it. Renamed silc_client_command_reply_whois_print to
5601 the silc_client_command_reply_whois_save.
5603 The client's idle time is also sent to the application now, and
5604 the idle is shown on screen.
5606 * Added silc_client_command_reply_identify_save to save the
5607 received IDENTIFY entries.
5609 * Do not check for channel private keys in message sending and
5610 reception if the channel does not have the PRIVKEY mode set.
5611 Affected file lib/silclient/client_channel.c.
5613 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5616 just surfaced after chaning the JOIN procedure.
5618 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added silc_client_get_clients_by_list to get client entries
5621 from Client ID list, that is returned for example by JOIN
5622 and USERS command replies. The application should use this
5623 function for example when JOIN command reply is received to
5624 resolve the clients already on the channel (library does not
5625 do that anymore as USERS command reply is not used in the JOIN
5626 procedure anymore). Affected files lib/silcclient/silcapi.h and
5627 lib/silcclient/idlist.c.
5629 * JOIN command reply and USERS command reply returns now SilcBuffer
5630 pointers instead of unsigned char pointers when returning
5631 the client list and mode list.
5633 * Added <Client ID> argument to the JOIN command reply, mainly
5634 for the server to identify for which client the command was
5635 originally sent. Updated protocol specs accordingly.
5637 * Added SilcDlist private_key pointer to the SilcChannelEntry
5638 in the client to support the channel private keys. Affected
5639 file is lib/silcclient/idlist.h.
5641 * Added SilcChannelPrivateKey argument to the function
5642 silc_client_send_channel_message so that application can choose
5643 to use specific private ke if it wants to. If it is not provided,
5644 the normal channel key is used, unless private keys are set.
5645 In this case the first (key that was added first) is used
5646 as the encryption key.
5648 * Implemented the support for channel private key handling.
5649 Implemented the following functions:
5651 silc_client_add_channel_private_key,
5652 silc_client_del_channel_private_keys,
5653 silc_client_del_channel_private_key,
5654 silc_client_list_channel_private_keys and
5655 silc_client_free_channel_private_keys
5657 Affected file lib/silcclient/client_channel.c.
5659 * Added the support for the private keys in the channel message
5660 sending and encryption and in the message reception and
5661 decryption. Affected funtions are
5662 silc_client_send_channel_message and silc_client_channel_message.
5664 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Added SKE's key verify callback to the client library's
5667 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5669 * Removed the statement that server (or router) must send USERS
5670 command reply when joining to the channel so that the client
5671 knows who are on the channel. Instead, the client list and
5672 client's mode list is now sent in the JOIN command reply to the
5673 client who joined channel. This is better solution.
5675 * Added function silc_server_get_users_on_channel and function
5676 silc_server_save_users_on_channel to the silcd/server.[ch].
5678 * Removed function silc_server_command_send_users from the
5681 * Do not show topic on the client library anymore. The topic is
5682 sent in the command reply notify to the application and the
5683 application must show the topic now.
5685 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added client searching by nickname hash into the IDENTIFY and
5688 WHOIS commands in the server as they were clearly missing from
5689 them. Affected file is silcd/command.c.
5691 * Fixed a bug in private message receiving in the client library.
5692 The remote ID was freed and it wasn't supposed, now it is
5695 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Minor fix to the channel payload; allocate the data area, as it
5698 needs to be of specific length.
5700 * If the key agreement port is zero then the operating
5701 system will define the bound port. Affected files are
5702 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5704 * Added new function silc_channel_payload_decrypt into the file
5705 lib/silccore/silcchannel.[ch].
5707 * Moved the channel message etc, check from silc_packet_decrypt
5708 to applications. The library calls now a generic
5709 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5710 when the packet is either normal or special. This was done to
5711 allow more wide range of checking that was not allowed when
5712 the code was in library. Now applications can do virtually any
5713 checks to the packet and return to the library the decision how
5714 the packet should be processed. Affected files are
5715 lib/silccore/silcpacket.[ch].
5717 Added silc_server_packet_decrypt_check to the server and
5718 silc_client_packet_decrypt_check to the client library.
5720 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5721 to send with specified source and destination information.
5723 * Channel message delivery between routers was broken after the
5724 channel key distribution was fixed earlier. The channel key
5725 was used be to distributed to other routers as well which is not
5726 allowed by the protocol. Now this is fixed and channel keys
5727 really are cell specific and the channel message delivery between
5728 routers comply with the protocol specification.
5730 * Fixed various commands in server to check also the global list
5731 for the channel entry and not just the local list. The affected
5732 file silcd/command.c.
5734 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Added assert()s to buffer formatting and unformatting routines
5737 to assert (if --enable-debug) when error occurs. Affected
5738 file: lib/silcutil/silcbuffmt.c.
5740 * Changed to auto-reconnect to check whether the remote host is
5741 router and register the re-connect timeout if it is. It used
5742 to check that whether we are normal server, but router must do
5743 auto-reconnect with another router as well. Affected file
5746 * Removed the [<key len>] option from CMODE command as the cipher
5747 name decides the key length, nowadays. See the defined ciphers
5748 from the protocol specification.
5750 * Added [<hmac>] option to the CMODE command to define the HMAC
5751 for the channel. Added SILC_CMODE_HMAC channel mode.
5753 * Added [<hmac>] option for the JOIN command so that user can
5754 select which HMAC is used to compute the MACs of the channel
5757 * Added Hmac field to the Channel Message Payload. The integrity
5758 of plaintext channel messages are now protected by computing
5759 MAC of the message and attaching the MAC to the payload. The
5760 MAC is encrypted. Now, it is clear that this causes some
5761 overhead to the size of the packet but rationale for this is that
5762 now the receiver can verify whether the channel message decrypted
5763 correctly and also when private keys are set for the channel the
5764 receiver can decrypt the packet with several keys and check from
5765 the MAC which key decrypted the message correctly.
5767 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5768 lib/silccrypt/silccipher.[ch].
5770 * Added silc_hash_len to return the digest length into the
5771 lib/silcrypt/silchash.[ch].
5773 * Rewrote parts of Silc Channel Payload interface in the
5774 lib/silccore/silcchannel.[ch]. The encode function now also
5775 encrypts the packet and parse function decrypts it.
5777 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Fixed a minor formatting bug in the SKE's key material processing.
5780 It actually might have processed the keys wrong way resulting
5783 * Redefined the mandatory HMAC algorithms and added new algorithms.
5784 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5785 and hmac-md5 truncated to 96 bits. The mandatory is now
5786 hmac-sha1-96. Rest are optional (including the one that used
5787 to be mandatory). Rationale for this is that the truncated HMAC
5788 length is sufficient from security point of view and can actually
5789 make the attack against the HMAC harder. Also, the truncated
5790 HMAC causes less overhead to the packets. See the RFC2104 for
5793 * Added new [hmac] configuration section. The SKE used to use
5794 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5795 is of course wrong. The official names that must be proposed in
5796 the SKE are the ones defined in the protocol specification
5797 (hmac-sha1-96 for example). The user can configure any hmac
5798 using any hash function configured in the [hash] section. At
5799 least, the mandatory must be configured.
5801 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5803 * Added HMAC list to the SKE proposal list. It has now both
5804 hash algorithm list and HMAC list. This makes the protocol
5805 incompatible with previous versions. The SKE now seems to work
5806 the way it is supposed to work, for the first time actually.
5808 * Defined plain Hash algorithms to the protocol specification.
5811 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Implemented support for key agreement packets into the server.
5814 Added functions silc_server_key_agreement and
5815 silc_server_send_key_agreement. Other than these functions,
5816 server has nothing to do with this packet.
5818 * Added support for private message key packets into the server.
5819 Added functions silc_server_private_message_key and
5820 silc_server_send_private_message_key.
5824 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5825 called in the protocol's final callback instead in the END
5826 protocol state. This makes a little more sense and in the same
5827 time in client we can use the same protocol routines for normal
5828 key exchange and to key agreement packet handling as well.
5830 * Added to both client's and server's KE protocol context the
5831 SilcSKEKeyMaterial pointer to save the key material. We will
5832 bring the key material to the protocol's final callback by doing
5833 this. The final callback must free the key material.
5835 * Added SKE's packet_send callback into client's KE protocol
5836 context so that the caller can choose what packet sending function
5837 is used. This way we can use different packet sending when
5838 doing normal SKE when doing key agreement packet handling (in
5839 the key agreement packet handling we do not want to encrypt
5842 * Implemented the responder side of the key agreement routines
5843 in the client. The client can now bind to specified port and
5844 accept incoming key negotiation. The key material is passed
5845 to the application after the protocol is over.
5847 * Implemented the processing of incoming Key Agreement packet
5848 in the client. Added function silc_client_key_agreement to
5851 * Implemented the intiator side of the key agreement routines
5852 in the client. The client can now initiate key agreement with
5853 another remote client. The key material is passed to the
5854 application after the protocol is over.
5856 * Created client_keyagr.c to include all the key agreement
5859 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5860 SILC_TASK_CALLBACK except that it is not static.
5862 * Created client_notify.c and moved the Notify packet handling
5863 from the client.[ch] into that file.
5865 * Created client_prvmsg.c and moved all private message and
5866 private message key routines from the client.[ch] into that file.
5868 * Create client_channel.c and moved all channel message and
5869 channel private key routines from the client.[ch] into that file.
5871 * Changed silc_client_get_client_by_id_resolve to resolve with
5872 WHOIS command instead of IDENTIFY command, in the file
5873 lib/silclient/idlist.c.
5875 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Implemented the SKE's responder side to the Client library.
5879 * When FAILURE is received to the protocol do not trust it
5880 blindly. Register a timeout to wait whether the remote closes
5881 the connection as it should do it, only after that process the
5882 actual failure. This was changed to both client and server.
5884 * Added client_internal.h to include some of the structures
5885 there instead of client.h in lib/silcclient/.
5887 * Added function silc_task_unregister_by_callback to unregister
5888 timeouts by the callback function.
5890 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Some "Incomplete WHOIS info" errors has been appearing on the
5893 log files. Took away the entry->userinfo check from WHOIS
5894 reply sending. The entry->userinfo is now " " if client did not
5895 provide one. I thought this was fixed earlier but something
5896 is wrong still. Let's see if the error still appears.
5898 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Fixed a minor bug in the login when the channel key is
5901 re-generated in the server. It used to generate the key in
5902 wrong order and thus caused problems in the channel traffic.
5904 * Fixed a minor bug in channel key distsribution after
5905 KICK command. The key was not sent to the router even though
5908 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Added silc_ske_process_key_material_data as generic routine
5911 to process any key material as the SILC protocol dictates. The
5912 function is used by the actual SKE library but can be used by
5913 applications as well. This relates to the private message keys
5914 and the channel private keys since they must be processed the
5915 same way the normal SILC session keys. The protocol dictates
5916 this. Affected files: lib/silcske/silcske.[ch].
5918 Added also silc_ske_free_key_material to free the
5919 SilcSKEKeyMaterial structure.
5921 * Defined silc_cipher_set_key function to set the key for
5922 cipher without using the object's method function. The affected
5923 files: lib/silccrypt/silccipher.[ch].
5925 * Implemented silc silc_client_add_private_message_key,
5926 silc_client_add_private_message_key_ske,
5927 silc_client_del_private_message_key,
5928 silc_client_list_private_message_keys and
5929 silc_client_free_private_message_keys functions in the
5932 Added functions silc_client_send_private_message_key to send
5933 the Private Message Key payload and silc_client_private_message_key
5934 to handle incoming Private Message Key payload.
5936 * Added Cipher field to the Private Message Key payload to set
5937 the cipher to be used. If ignored, the default cipher defined
5938 in the SILC protocol (aes-256-cbc) is used.
5940 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Removed lib/silcclient/ops.h file.
5944 Redefined parts of the SILC Client Library API. Created new
5945 file silcapi.h that deprecates the ops.h file and defines the
5946 published Client Library API. Defined also private message key
5947 API and channel private key API into the file.
5949 This is the file that the application must include from the
5950 SILC Client Library. Other files need not be included by
5951 the application anymore.
5953 * Added new key_agreement client operation callback and also
5954 defined the Key Agreement library API for the application.
5956 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5959 is used by clients to request key negotiation between another
5960 client in the SILC network. If the negotiation is started it
5961 is performed using the SKE protocol. The result of the
5962 negotiation, the secret key material, can be used for example
5963 as private message key.
5965 Implemented the Key Agreement payload into the files
5966 lib/silccore/silauth.[ch].
5968 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Redefined ciphers for the SILC protocol. Added some new ciphers
5971 and defined the key lengths for the algorithms. Changed the
5972 code accordingly. The default key length is now 256 bits.
5974 * Fixed SKE key distribution function silc_ske_process_key_material
5975 when the key length is more than 128 bits. The default key
5976 length in SILC is now 256 bits.
5978 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5979 to indicate unsupported algorithm.
5981 * Renamed rijndael.c to aes.c and all functions as well.
5983 * Fixed a long standing channel key setting bug in client library.
5984 Weird that it has never surfaced before.
5986 * Fixed bug in channel deletion. If the entire channel is removed
5987 then it must also delete the references of the channel entry
5988 from the client's channel list as the client's channel entry and
5989 the channel's client entry share same memory.
5991 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Implemented CONNECT and SHUTDOWN commands in the client.
5995 * Implemented CLOSE command to the client.
5997 * Added the function silc_idlist_find_server_by_name into the
5998 files silcd/idlist.[ch].
6000 Added the function silc_idlist_find_server_by_conn into the
6001 files silcd/idlist.[ch].
6003 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * DIE command was renamed to SHUTDOWN. Updated the both code
6008 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6009 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6011 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6014 * Added function silc_server_create_connection function to create
6015 connection to remote router. My server implementation actually
6016 does not allow router to connect to normal server (it expects
6017 that normal server always initiates the connection to the router)
6018 so the CONNECT command is only good for connecting to another
6021 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6024 or some other client was kicked from the channel.
6026 Implemented the handling of the notify type to both client
6029 Implemented silc_server_send_notify_kicked to send the KICKED
6030 notify. It is used to send it to the server's primary router.
6032 * Implemented the KICK command into server and client.
6034 * Added `query' argument to the silc_idlist_get_client function
6035 to indicate whether to query the client from server or not if
6038 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6039 to indicate that the client is not channel founder.
6043 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Removed the rng context from SilcPacketContext structure and
6046 changed that the packet routine uses the Global RNG API.
6048 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Added support for quit message that client can "leave" on the
6051 channel when it quits the SILC. It is ditributed inside the
6052 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6054 Added silc_server_free_client_data that will take the
6055 signoff message as argument.
6057 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6059 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Updated parts of the protocol specification to keep it up
6064 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6067 payloads in one packet.
6069 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6070 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6071 use now the new List flag.
6073 * Also deprecated the following packet types: REPLACE_ID,
6074 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6076 * Added list support for Notify packet in server.
6078 * Added silc_server_send_notify_channel_change to send the
6079 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6080 the silc_server_send_replace_id.
6082 * Added silc_server_send_notify_nick_change to send the
6083 NICK_CHANGE notify type. Deprecates the function
6084 silc_server_send_replace_id.
6086 * Added silc_server_send_notify_join to send the JOIN notify type.
6087 Deprecates the function silc_server_send_new_channel_user.
6089 * Added silc_server_send_notify_leave to send LEAVE notify type.
6090 Deprecates the function silc_server_send_remove_channel_user.
6092 * Added silc_server_send_notify_cmode and
6093 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6094 types. Deprecates the silc_server_send_set_mode function.
6096 * Added SERVER_SIGNOFF notify type to indicate that server has
6097 quit. This means that all clients on the channel from that
6098 server will drop. This can be also used when netsplit happens.
6100 Deprecated REMOVE_ID packet type since it is not needed anymore
6103 Added silc_server_send_notify_server_signoff to send the
6104 SERVER_SIGNOFF notify type. Deprecates the function
6105 silc_server_send_remove_id.
6107 Added also silc_server_send_notify_signoff to send the
6108 SIGNOFF notify type.
6110 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6111 SILC protocol from this day on. Changed the protocol
6112 specification as well.
6114 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6115 notify type. It is used between routers to notify about
6116 topic changes on a channel.
6118 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6121 * Partly updated the protocol specification to comply with the
6122 changes now made. It is still though a bit outdated.
6124 * The JOIN notify type now takes one extra argument <Channel ID>.
6125 The packet used to be destined to the channel but now the
6126 JOIN type may be sent as list thus it is impossible to
6127 destine it to any specific channel. By adding this argument
6128 it is again possible.
6130 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Added CREDITS file. The CHANGES and CREDITS file will appear
6133 in the distribution as well.
6135 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6137 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6138 types in the server's silcd/packet_receive.c.
6140 * Implemented CMODE and CUMODE to work in router environment.
6142 * Fixed minor encoding and decoding buglet from the
6143 lib/silccore/silcmode.c.
6145 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6148 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6150 * Changed all SilcConfigServer* and silc_config_server* to
6151 SilcServerConfig* and silc_server_config*, respectively.
6154 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Associated the ID (client or server ID) to the Authentication
6157 Payload to avoid any possibility of forging. Updated the
6158 protocol specification and the code accordingly.
6160 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * The RSA key length is now save to the RsaKey context in the
6163 key generation process in lib/silccrypt/rsa.c. The key length
6164 is now used to figure out the maximum size of the block allowed
6165 to be encrypted/signed.
6167 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6168 is equivalent to the silc_mp_mp2bin but does not allocate any
6171 * Changed silc_mp_mp2bin API to take length argument. If it is
6172 non-zero then the buffer is allocated that large. If zero, then
6173 the size is approximated using silc_mp_sizeinbase, which however
6176 * Created Global RNG API which is global RNG that application can
6177 initialize. After initializing, any routine anywhere in the
6178 code (including library) can use RNG without allocating a new
6179 RNG object. This was done to allow this sort of use of the
6180 RNG in code that has no chance to allocate RNG object. All
6181 applications currently allocate this and many routines in the
6182 library use this. Affected file lib/silccrypt/silcrng.[ch].
6184 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6185 it to use the Global RNG API.
6187 * Defined Authentication Payload into protocol specification that
6188 is used during SILC session to authenticate entities. It is
6189 used for example by client to authenticate itself to the server
6190 to obtain server operator privileges.
6192 Implemented this payload into the lib/silccore/silcauth.[ch].
6193 Implemented also routines for public key based authentication
6194 as the new protocol specification dictates.
6196 Moved definitions of different authentication methods from
6197 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6199 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6200 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6201 silc_pkcs_verify_with_hash functions into the file
6202 lib/silccrypt/silcpkcs.[ch].
6204 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * The client entry's userinfo pointer must be always valid.
6207 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6208 will fail since it requires the userinfo. Now, the userinfo
6209 is allocated as "" if actual userinfo does not exist. Actually,
6210 it must exist and it is totally Ok to drop client connections
6211 that does not announce the userinfo. However, we will make
6212 this workaround for now.
6214 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6215 to return the remote port by socket.
6217 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6220 SILC_SERVER_PENDING_EXEC and added an new macro
6221 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6222 data or when error occurs while processing the pending command.
6224 Added new argument `destructor' into silc_server_command_pending
6225 and to the SilcServerCommandPending object. This destructor is
6226 now called after calling the pending callback or if error occurs
6227 immediately. If error occurs the actual pending callback won't
6228 be called at all - only the destructor. The destructor may be
6229 NULL if destructor is not needed.
6231 All this applies for client library code as well. Similar
6232 changes were made there as well for the pending commands.
6234 In the client, the application must now allocate the
6235 SilcClientCommandContext with the silc_client_command_alloc
6238 * Added reference counter to the SilcServerCommandContext. Added
6239 function silc_server_command_alloc and silc_server_command_dup
6242 Same type of functions added to the client library for the same
6245 * Removed the cmd_ident from IDListData away since it is now
6246 global for all connections. It is the command identifier used
6247 in command sending and with pending commands. The affected file
6250 * Added reference counter to the SilcSocketConnection objecet to
6251 indicate the usage count of the object. The object won't be
6252 freed untill the reference counter hits zero. Currently only
6253 server uses this, and client ignores it. The client must be
6254 set to use this too later. The affected files are
6255 lib/silccore/silcsockconn.[ch]. Added also the function
6256 silc_socket_dup to increase the reference counter.
6258 This was mainly added because it is possible that the socket
6259 is removed underneath of pending command or other async
6260 operation. Now it won't be free'd and proper DISCONNECTING
6261 flags, etc. can be set to avoid sending data to connection that
6262 is not valid anymore.
6264 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6265 the connection. After that it sets SILC_SET_DISCONNECTED.
6266 It is, however, possible that the socket data is not still freed.
6267 The silc_server_packet_process now checks that data is not
6268 read or written to connection that is DISCONNECTED. The socket
6269 get's freed when the reference counter hits zero.
6271 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Changed the client operation API: channel_message operation's
6274 `sender' is now the client entry of the sender, not the nickname
6275 and the `channel' is the channel entry, not the channel name.
6277 In the private_message operation the `sender' is now also the
6278 client entry of the sender not the nickname.
6280 Affected file is lib/silcclient/ops.h and all applications
6281 using the client operations.
6283 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Moved the calling of ops->connect() from connect_to_server_final
6286 into receive_new_id functin since that is the point when the
6287 client is actually allowed to send traffic to network. The
6288 affected file is lib/silcclient/client.c.
6290 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6293 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6294 (if needs broadcasting) instead of broadcasting the packets one
6295 by one which would make a burst in the network traffic.
6297 * Added `broadcast' argument to the functions in silcd/server.[ch]
6298 silc_server_create_new_channel[_with_id] to indicate whether
6299 to send New Channel packet to primary router.
6301 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Added new function into the silcd/server.[ch] files:
6304 silc_server_create_new_channel_with_id to create new channel with
6305 already existing Channel ID.
6307 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6308 lib/silccore/silcpacket.h. This packet is used t send list of
6309 Set Mode payloads inside one packet. Server uses this to set
6310 the modes for the channels and clients on those channels, that it
6311 announced to the router when it connected to it. The protocol
6312 specification has been updated accordingly.
6314 * The silc_server_new_channel did not handle the packet coming
6315 from normal server as it normally does not send that. However,
6316 when it announces its channels it does send it. Implemented
6317 the support for that.
6319 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6320 into the file lib/silccore/id.h.
6322 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Fixed memory leaks in the functions silc_idlist_del_client,
6325 silc_idlist_del_channel and silc_idlist_del_server in the file
6326 silcd/idlist.c. All of those leaked like a sieve.
6328 * Fixed some small memory leaks in the client's function
6329 silc_client_notify_by_server.
6331 * Added functions into silcd/server.c: silc_server_announce_clients,
6332 silc_server_announce_channels and silc_server_announce_server.
6333 These functions are used by normal and router server to announce
6334 to its primary router about clients, channels and servers (when
6335 router) that we own. This is done after we've connected to the
6338 These functions effectively implements the following packet types:
6339 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6340 and SILC_PACKET_NEW_ID_LIST.
6342 * Added new functions into the silcd/packet_receive.[ch]:
6343 silc_server_new_id_list, silc_server_new_channel_list and
6344 silc_server_new_channel_user_list to handle the incoming
6345 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6347 * Added support of changing Channel ID in the function
6348 silc_server_replace_id. If the server that announces a channel
6349 to the router already exists in the router (with same name but
6350 with different Channel ID), router is responsible to send
6351 Replace ID packet to the server and force the server to change
6352 the Channel ID to the one router has.
6354 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6355 client that the Channel ID has been changed by the router. The
6356 normal server sends this to the client. Client must start using
6357 the new Channel ID as the channel's ID.
6359 Implemented handling of this new type into lib/silcclient/client.c
6360 into the function silc_client_notify_by_server.
6362 * Added new function silc_idlist_replace_channel_id into the files
6363 silcd/idlist.[ch] to replace the Channel ID.
6365 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Call silc_server_command_identify_check always when processing
6368 the IDENTIFY command in silcd/command.c
6370 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6373 send keepalive packets. The packet can be sent by clients,
6374 servers and routers.
6376 Added function silc_socket_set_heartbeat into the file
6377 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6378 If not set, the heartbeat is not performed. The actual
6379 heartbeat is implemented in the low level socket connection
6380 library. However, application is responsible of actually
6383 Added silc_server_send_heartbeat to send the actual heartbeat
6384 packet into silcd/packet_send.[ch]. Server now performs
6385 keepalive with all connections.
6387 * Added silc_task_get_first function into lib/silcutil/silctask.c
6388 to return the timeout task with shortest timeout. There was a bug
6389 in task unregistration that caused problems. TODO has been
6390 updated to include that task system must be rewritten.
6392 * The client library will now resolve the client information when
6393 receiving JOIN notify from server for client that we know but
6394 have incomplete information.
6396 * Rewrote parts of silc_server_remove_from_channels and
6397 silc_server_remove_from_one_channel as they did not remove the
6398 channel in some circumstances even though they should've.
6400 * Encryption problem encountered in server:
6402 The LEAVE command used to send the Channel Key packet to the
6403 router immediately after generating it. However, the code
6404 had earlier sent Remove Channel user packet but not immediately,
6405 ie. it was put to queue. The order of packets in the router
6406 was that Channel Key packet was first and Remove Channel User
6407 packet was second, even though they were encrypted in the
6408 reverse order. For this reason, MAC check failed. Now, this
6409 is fixed by not sending the Channel Key packet immediately but
6410 putting it to queue. However, this is more fundamental problem:
6411 packets that are in queue should actually not be encrypted
6412 because packets that are sent immediately gets encrypted
6413 actually with wrong IV (and thus MAC check fails). So, packets
6414 that are in queue should be encrypted when they are sent to
6415 the wire and not when they put to the queue.
6417 However, the problem is that the current system has not been
6418 designed to work that way. Instead, the packet is encrypted
6419 as soon as possible and left to the queue. The queue is then
6420 just purged into wire. There won't be any fixes for this
6421 any time soon. So, the current semantic for packet sending
6424 o If you send packet to remote host and do not force the send
6425 (the packet will be in queue) then all subsequent packets to the
6426 same remote host must also be put to the queue. Only after the
6427 queue has been purged is it safe again to force the packet
6430 o If you send all packets immediately then it safe to send
6431 any of subsequent packets through the queue, however, after
6432 the first packet is put to queue then any subsequent packets
6433 must also be put to the queue.
6435 Follow these rules and everything works fine.
6437 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Added new function silc_server_remove_clients_by_server to
6440 remove all client entries from ID list when the server connection
6441 is lost. In this case it is also important to invalidate all
6442 client entires as they hold the invalid server entry. This
6443 fixes fatal bug when server has lost connection and will reconnect
6446 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Made some sanity checks to silc_server_daemonise like to check
6449 whether the requested user and group actually exists.
6451 * Added sanity check to SKE's silc_ske_responder_finish to check
6452 that the public and private key actually is valid.
6454 * Invalidate the client's nickname when receiving Replace ID
6455 packet and the Client ID is being replaced. This means that the
6456 server will query the nickname if someone needs it (client)
6459 * Sort the ID Cache in client library when the ID Cache data
6460 has changed (needs sorting).
6462 * Do not allow for SILC client to create several connections to
6463 several servers. The client does not support windows right now
6464 and generating multiple connections causes weird behaviour.
6466 Irssi-silc client does support windows and can handle several
6467 connections without problems, see: www.irssi.org and SILC plugin.
6469 * Fixed some places where client was added to the IDList. The
6470 rule of thumb is following (in order to get everything right):
6471 If the client is directly connected local client then the
6472 `connection' argument must be set and `router' argument must be
6473 NULL to silc_idlist_add_client function. If the client is not
6474 directly connected client then the `router' argument must
6475 bet set and the `connection' argument must be NULL to the
6476 silc_idlist_add_client function.
6478 * The funtion silc_server_packet_send_local_channel actually did
6479 not check whether the client was locally connected or not. It
6480 does that now. Fixed a bug related to LEAVE command.
6482 * Fixed Remove Channel User payload parsing bug in server's
6483 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6485 * The server's silc_server_save_channel_key now checks also the
6486 global ID list for the channel as it might not be in the local
6487 list. Fixed a bug related to LEAVE command.
6489 * Is this the end of the [<unknown>] buglet that has been lurking
6490 around for a long time? A little for loop fix in server's
6491 silc_server_command_whois_parse that is used by both IDENTIFY
6492 and WHOIS command. At least, this was a clear bug and a cause
6493 of one type of [<unknown>] buglet.
6495 * WHOIS and IDENTIFY commands call the function
6496 silc_server_command_[whois/identify]_check function even if
6497 we are not router server.
6499 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Added --with-gmp configuration option. If set the GMP
6502 is always compiled in the SILC source tree. If not set then
6503 it is checked whether the system has the GMP3 installed. If
6504 it has then the GMP won't be compiled (the system's headers
6505 and library is used), if it doesn't have it then the GMP is
6506 compiled in the SILC source tree.
6508 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Changed RSA private exponent generation to what PKCS #1
6511 suggests. We try to find the smallest possible d by doing
6512 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6513 not security fix but optimization.
6515 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Added new config entry [Identity] to fork the server and run
6518 it as specific user and group. A patch from Bostik.
6520 * Imported Dotconf configuration library into lib/dotconf.
6521 This will be used to create the SILC configuration files later.
6522 It will appear in the distsribution after this commit.
6524 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * A big code auditing weekend happening. Auditing code for
6527 obvious mistakes, bugs and errors. Also, removing any code
6530 Removed files for being obsolete:
6532 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6533 inline in the file lib/silcutil/silcbuffer.h)
6535 o lib/silcutil/silcbufutil.c (the header has inline versions)
6537 Changed code to fix possible error conditions:
6539 o The buffer formatting routines now check that the destination
6540 buffer really has enough space to add the data. This applies for
6541 both buffer formatting and unformatting
6542 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6543 unformatting was changed to accomodate following rules:
6544 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6545 sent to the function while XXX_*STRING will not allocate or copy
6546 the data into the buffer. Instead it sets the pointer from the
6547 buffer into the pointer sent as argument (XXX_*STRING used to
6548 require that the pointer must be allocated already). This change
6549 makes this whole thing a bit more consistent and more optimized
6550 (note that the data returned in the unformatting with XXX_*STRING
6551 must not be freed now). The routines return now -1 on error.
6553 o Tried to find all code that use buffer_format and buffer_unformat
6554 and added return value checking to prevent formatting and
6555 especially unformatting errors and possible subsequent fatal
6558 o Changed ske->x and ske->KEY to mallocated pointers in
6559 lib/silcske/silcske.h. Fixed possible data and memory leak.
6561 o Added return value checking to all *_parse* functions. Fixed
6562 many memory leaks as well.
6564 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6565 so that buffer overflows would not happen. All code now also
6566 checks the return value as it can fail.
6568 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Added reconnection support to server if the normal server looses
6571 its connection to the router (for example if router is rebooted).
6572 The server performs normal reconnection strategy implemented
6573 to the server. Affected file silcd/server.c.
6575 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Added new packet type SILC_PACKET_SET_MODE that is used to
6578 distribute the information about changed modes (for clients,
6579 channels and clients channel modes) to all routers in the
6580 network. Updated the protocol specification accordingly.
6582 Added functions into silcd/packet_send.c and
6583 silcd/packet_receive.c: silc_server_send_set_mode,
6584 silc_server_set_mode.
6586 Added new files silcmode.[ch] into lib/silccore that implements
6587 the encoding and decoding of Set Mode Payload. Added new type
6588 SilcSetModePayload. Moved the definitions of different modes
6589 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6591 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Oops, a little mistake in server's connection authentication
6594 protocol. The protocol is not ended with FAILURE but with
6595 SUCCESS if the authentication is Ok. :) Affected file is
6598 * Implemented NICK_CHANGE notify handling in server in the file
6599 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6600 the local clients on the channel. After the changing nickname
6601 in router environment snhould work and the [<unknown>] nickname
6602 should appear no more.
6604 The silc_server_replace_id function that receives the Replace ID
6605 payload now sends the NICK_CHANGE notify type also in the file
6606 silcd/packet_receive.c
6608 * Changed WHOIS and IDENTIFY command to support the maximum amount
6609 of arguments defined in protocol specs (3328 arguments). This
6610 fixed a bug that caused problems when there were more than three
6613 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Added extra parameter, command identifier, to the
6616 silc_client_send_command so that explicit command identifier
6619 Changed that ID list routines uses specific command identifier
6620 when sending WHOIS/IDENTIFY requests to the server so that they
6621 can be identified when the reply comes back.
6623 Affected files lib/silcclient/command.[ch],
6624 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6626 * Added `sender' argument to silc_server_packet_send_to_channel
6627 to indicaet the sender who originally sent the packet to us
6628 that we are now re-sending. Ignored if NULL. Affected file
6629 silcd/packet_send.[ch].
6631 * Added some server statistics support in silcd/server_internal.h
6632 SilcServerStatistics structure and around the server code. Also
6633 send some nice statistics information when client is connecting
6636 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Fixed channel ID decoding in server's JOIN command reply in
6639 silcd/command_reply.c
6641 * Fixed braodcasting of replace ID payload to not to send it if
6642 we are standalone server in silcd/packet_receive.c.
6644 * Fixed all channel message sending routines to not to send
6645 packets to clients that has router set, since they are routed
6646 separately in the same function earlier. Affects file
6647 silcd/packet_send.c and all channel packet sending functions.
6649 * In USERS reply, res_argv[i] are not allocated, the table
6650 is allocated. Thus changed that free the table, not its
6653 * In server's whois_check and identify_check if the client is
6654 locally connected do not send any WHOIS commands - they are not
6657 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Fixed some minor bugs in client when sending WHOIS command. The
6660 arguments was in wrong order.
6662 * Removed statis function add_to_channel from server in
6663 silcd/command.c that was previously used with the joining but
6666 * Tested USERS command in router environment successfully with two
6667 routers, two servers and two clients.
6669 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Reorganized the USERS command and command reply in client library
6672 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6673 When the command is given by user we register a pending command
6674 callback that will reprocess the command after the reply has been
6675 received from the server. When reprocessing the packet we then
6676 display the information. Thus, the USERS information is displayed
6677 now in the command callback instead of in the command reply
6678 callback. The processing of the command is same as previously
6679 when server has sent the command reply in the JOINing process.
6681 * Added to USERS command in silcd/command_reply.c to join the client,
6682 we didn't use to know about, to the channel after we've created
6683 a client entry for it. Also, for clienet we did know already still
6684 check whether it is on the channel or not and add it if not.
6686 * Removed silc_server_command_join_notify as the function and its
6689 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6691 * Changed the client's pending command handling to the same as the
6692 server's pending command handling. It is also now possible to
6693 execute command reply functions from other command reply
6694 function as the function callbacks for commands and command
6695 replies are one and same. The pending commands are not static
6696 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6697 in client connection context. Thus, pending commands are server
6698 connection specific as it is convenient.
6700 Changed the function silc_client_command_pending and
6701 silc_client_command_pending_del and added new function
6702 silc_client_command_pending_check. Removed the
6703 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6706 * Added cmd_ident, current command identifier, to the client
6707 connection context in lib/silcclient/client.h to keep track on
6708 command identifiers used in command sending. Client's command reply
6709 function handling now supports the mandatory command identifiers.
6711 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6712 funtions in client to fully support pending command callbacks.
6714 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6715 as one of the arguments to the application in the command reply
6718 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6719 before first releasing SILC but came back. Now it is removed again
6720 and should come back nomore. The FORWARDED flag was used only
6721 by the JOINing procedure by forwarding the command packet to router.
6722 Now, the JOINing procedure has been changed to more generic (due
6723 to various router environment issues) and FORWARDED is not needed
6724 anymore for anything. The protocol specification is yet to be
6727 Now, removed silc_server_packet_forward from server and the flag
6728 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6730 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Renamed NAMES command to USERS command. The NAMES was named that
6733 due to historical reasons. Now it is renamed. Also, rewrote
6734 parts of the USERS command. The nickname list is not sent anymore
6735 by the server. Only Client ID and mode lists are sent in the USERS
6736 command. Changed this also to the protocol specification.
6738 The client now resolves the names and stuff after it receives
6739 the USERS list from the server when joining to the channel.
6741 * WHOIS and IDENTIFY commands has been changed to support multiple
6742 Client ID's per command. One can now search for multiple users
6743 in the network by sending only one WHOIS or IDENTIFY command.
6744 Changed the code and the protocol specifications.
6746 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6747 uses silc_server_command_whois_parse to parse the request. */
6749 * If normal server, do not parse the WHOIS and IDENTIFY requests
6750 before sending it to the router. Saves some time.
6752 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Fixed JOIN command on client library. Wrong number of arguments
6755 used to crash the client.
6757 * Added silc_server_channel_has_global function to check whether
6758 channel has global users or not.
6760 * Added silc_server_channel_has_local function to check whether channel
6761 has locally connected clients on the channel.
6763 * The silc_server_remove_from_one_channel now checks whether the
6764 channel has global users or not after given client was removed from
6765 the channel. It also checks whether the channel has local clients
6766 on the channel anymore. If it does not have then the channel entry
6767 is removed as it is not needed anymore.
6769 * The silc_server_notify now checks on JOIN notify whether the joining
6770 client is one of locally connected or global. If it is global then
6771 the channel has now global users on the channel and that is marked
6772 to the channel entry. Also, it now saves the global client to
6773 global list who is joining and JOINs it to the channel. This is
6774 for normal server, that is.
6776 Changed silc_server_send_notify_on_channel,
6777 silc_server_packet_relay_to_channel and
6778 silc_server_packet_send_to_channel check if we are normal server
6779 and client has router set (ie. global client) do not send the
6780 message to that client, as it is already routed to our router.
6782 * Implemented LEAVE notify type handling in silc_server_notify
6785 * Tested LEAVE command in router environment successfully. Tested
6786 with two routers, two servers and two clients.
6790 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6792 * Implemented SIGNOFF notify type handling in silc_server_notify
6795 * silc_server_remove_id now removes the client entry from all channels
6796 it has joined and thusly sends SIGNOFF notify type.
6798 * Rewrote the NAMES list generation in server by removing two excess
6799 loops. The lists are created now inside one loop.
6801 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * silc_server_remove_channel_user checks now also global list
6804 for channel and client.
6806 * silc_server_new_channel_user checks now both local and global
6807 list for channel and client. Fixed a bug in client id decoding.
6808 Used to decode wrong buffer.
6810 * silc_server_channel_message checks now both local and global
6811 list for channel entry.
6813 * Tested channel joining (hence JOIN) in router environment
6814 successfully. Tested with two routers, two servers and two
6817 * Tested channel message sending in router environment successfully.
6819 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Added silc_server_save_channel_key into server.[ch] to save the
6822 received channel key in Channel Key payload processing. It is
6823 also used in JOIN command reply handling.
6825 Equivalent function silc_client_save_channel_key added into
6826 client.[ch] into client library.
6828 * Changed JOIN command reply to send information whether the channel
6829 was created or not (is existing already) and the channel key
6830 payload. Changed protocol specs accordingly.
6832 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6833 the request was sent by ID and not by nickname. Crashed on
6836 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6839 now correctly save the received data.
6841 * silc_server_free_sock_user_data now notifies routers in the
6842 network about entities leaving the network.
6844 At the same time implemented functions silc_server_remove_id
6845 and silc_server_send_remove_id to receive and send REMOVE_ID
6846 packets. The packet is used to notify routers in the network
6847 about leaving entities. The ID removed will become invalid in
6850 * Added function silc_idlist_del_server into server. Removes and
6851 free's server entry from ID list.
6853 * silc_server_private_message function now checks, if we are router,
6854 that the destination ID really is valid ID, naturally.
6856 * In router when NEW_ID packet is received (for new client) the
6857 hash of the Client ID is saved in the ID Cache but the
6858 client->nickname is set to NULL, instead of putting the hash
6861 IDENTIFY command now also checks that client->nickname must be
6862 valid. If it is not if will request the data from the server who
6863 owns the client. Added new function
6864 silc_server_command_identify_check.
6866 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6867 to set the command to already allocated Command Payload.
6869 * Tested private message sending in router environment with two
6870 routers, two servers and two clients. Fixed minor bugs and now
6873 * Fixed segfault from client's NAMES command. Used to crash if
6876 * Forwarded packets must not be routed even if it is not destined
6877 to the receiver. Changed server code comply with this.
6879 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Added `require_reverse_mapping' boolean value to ServerParams
6882 structure. If TRUE (not default) the server will require that
6883 the connecting host has fully qualified domain name.
6885 If the reverse mapping is not required and hostname could not be
6886 found the IP address is used as hostname.
6888 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Implemented version string checking to both client and server.
6891 The check is incomplete currently due to the abnormal version
6892 strings used in development version of SILC.
6894 * Changed all command functions in server to use the new
6897 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Changed char *data to unsigned char *data in ID Cache system to
6900 support binary data as ID Cache data. Changed code to support
6901 binary data in lib/silccore/idcache.c.
6903 * Renamed silc_server_packet_relay_command_reply to
6904 silc_server_command_reply as it is normal packet receiving
6905 function. Rewrote the function to accept command replys for
6906 servers and not only for clients.
6908 * Mark remote router always as registered server if we are connecting
6909 to it. Otherwise, commands sent by the router to us are ignored.
6911 * All ID List find routines now returns the ID Cache Entry pointer
6912 as well if requested.
6914 * WHOIS command works now in router environment, tested with two
6915 routers, two servers and two clients.
6917 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6918 in router environment (as it is almost equivalent to WHOIS) but
6919 hasn't been tested thoroughly. Added new functions:
6921 silc_server_command_identify_parse
6922 silc_server_command_identify_send_reply
6923 silc_server_command_identify_from_client
6924 silc_server_command_identify_from_server
6926 * Disabled route cache adding because adding two different ID's with
6927 same IP replaces the old cache entry thus giving wrong route.
6928 The entry->router->connection is always the fastest route anyway
6929 so route cache may not be needed. Of course, new routes maybe
6930 established after receiving the ID when the entry->router->connection
6931 might not be anymore the most optimal.
6933 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Add route cache for received ID for fast routing.
6937 * Added silc_server_packet_route to route received packet on router
6938 that is not destined to us.
6940 * Renamed silc_server_get_route to silc_server_route_get.
6942 * Added id_string and id_string_len fields into SilcServer to
6943 include encoded ServerID for fast comparing without excess
6944 encoding of the ID's.
6946 * Cleaned up WHOIS command on server side. Added following static
6949 silc_server_command_whois_parse
6950 silc_server_command_whois_check
6951 silc_server_command_whois_send_reply
6952 silc_server_command_whois_from_client
6953 silc_server_command_whois_from_server
6955 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6956 arguments in command replies. All command functions should be
6957 updated to use this macro.
6959 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6961 * Minor typo fixes on command reply handling on server.
6963 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6965 * Added silc_server_command_add_to_channel internal routine to add
6966 the client to the channel after router has created the channel and
6967 sent command reply to the server.
6969 * Added generic silc_server_send_command to send any command from
6972 * Use static buffer with ID rendering instead of duplicating data.
6974 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Fixed a channel user mode bug when joining to a channel server gave
6977 everybody channel founder rights, oops.
6979 * We mark ourselves as the router of the incoming server connection
6980 if we are router ourselves. This way we can check in some packet
6981 sending functions whether it is locally connected server. For
6982 incoming router connections we put NULL.
6984 * For router sending packets locally means now always sending the
6985 packet cell wide; to local clients and local servers. For normal
6986 server sending packet locally means sending it to only local
6989 * Fixed the JOIN command to really work in router environment. If the
6990 channel is created it is always created by the router. Router is
6991 also responsible of making the initial joining to the channel,
6992 sending JOIN notify to the sending server and distributing
6993 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6994 does not exist server doesn't do anything else but forward the
6995 command to the router which performs everything.
6997 * Added silc_server_send_channel_key function to send the Channel Key
7000 * Added silc_server_create_channel_key to create new channel key. The
7001 channel key is now re-generated everytime someone joins or leaves
7002 a channel, as protocol dictates. Note: channel->key_len is the
7005 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7008 packet_receive.[ch] to separate packet sending and receiving
7009 routines. The server.[ch] now includes everything else including
7010 actual packet processing (writing and reading data) and other
7013 Renamed silc_server_private_message_send_internal to
7014 silc_server_send_private_message. The routine is still though
7015 used only to relay private messages as server does not send
7016 private messages itself.
7018 Renamed silc_server_new_channel to silc_server_create_new_channel
7019 and added new function sicl_server_new_channel that handles the
7020 incoming New Channel packet. Added also new sending function
7021 silc_server_send_new_channel to send New Channel Payload.
7023 * Added new function silc_server_notify to process incoming notify
7024 packet to the server/router. Server may then relay the notify
7025 to clients if needed.
7027 * Added new function silc_server_new_channel_user to process incoming
7028 New Channel User packet. Router will redistribute the packet and
7029 send JOIN notify to its local clients and locally connected servers
7030 if needed. Normal server will send JOIN notify to its local client
7031 on same channel when received this packet. Added also corresponding
7032 sending function silc_server_send_new_channel_user to sent the
7035 * Added boolean route argument to send_notif_to_channel and
7036 packet_send_to_channel functions to attempt to route the packet
7037 if it is TRUE and send only locally if it is FALSE.
7039 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7041 * silc_server_replace_id now broadcasts the received replace ID
7042 packet if it is not broadcast packet already. The router must
7043 broadcast to inform other routers about changed ID.
7045 * Added backpointer to server's router into SilcServer context in
7046 silcd/server_internal.h.
7048 * Fixed silc_server_packet_broadcast to send correct broadcast
7051 * The channel key is now distributed to the local client as soon
7052 as it is received from the router (in router environment) so that
7053 no other packet may be sent for the channel until client has
7056 * silc_server_remove_channel_user now broadcasts the received
7057 Remove Channel User packet if it is not broadcast packet already.
7058 The router must broadcast to inform other routers about removed
7061 * Added users field into SilcPacketContext that is a reference count
7062 of the context. One can increase the reference count by calling
7063 silc_packet_context_dup which is now changed to just increase the
7064 reference count instead of duplicating the data. The reference
7065 count is decresed by calling silc_packet_context_free that will
7066 free the data after the reference count hits zero.
7068 For now on the packet context and everything allocated into it
7069 (including the raw packet from network) must be freed by calling
7070 the new silc_packet_context_free function. Added also new function
7071 silc_packet_context_alloc that must be used now to allocate the
7072 context. This also means that if a routine is asynchronous from
7073 silc_[client/server]_packet_parse_type the packet context must
7074 be duplicated by calling silc_packet_context_dup. Otherwise it
7075 gets free'd after silc_[client/server]_packet_parse_type returns.
7076 Also, one must remember that if packet is duplicated then its
7077 reference count must be decresed by calling the free function as
7078 many times as it was duplicated.
7080 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7081 from both client and server.
7083 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Made joining to a channel working in router environment.
7087 * Cleaned up JOIN command on server side and create function
7088 silc_server_command_join_channel internal routine to make the
7091 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Changed silc_command_pending list to SilcDList. Also, added
7094 `ident' field to SilcServerCommandPending structure to identify
7095 the reply and to call correct callback.
7097 Added silc_server_command_pending_check function to replace the
7098 corresnponding macro. The silc_command_pending list is not
7101 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7102 to set identifier to previously allocated Command Payload. It
7103 is used to set identifier for command when resending Command
7106 * Added silc_command_payload_encode_payload to encode Command
7107 Payload buffer from SilcCommandPayload structure.
7109 * Added silc_argument_payload_encode_payload to encode Argument
7110 payload buffer from SilcArgumentPayload structure.
7112 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Changed WHOIS command to support router connection on server side.
7115 The whois request is always sent to router unless the server is
7116 standalone server. After server has received the reply from the
7117 router will it send the reply to the client.
7119 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7120 broadcast received broadcast packet. The function is used only
7121 by router. The broadcast packet is always sent to the router's
7124 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7125 render given ID to printable string, for log files for example.
7127 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Made basic router to router connections working. At least they
7130 can now connect to each other but nothing really works the way
7131 they are supposed - yet.
7133 * Added new initiator token to RouterConnection configuration
7134 file in silcd/serverconfig.[ch]. It is used to tell whether we
7135 are the initiator to the remote router or whether we'll expect
7136 the other end to connect.
7138 * Moved registering of listener task to silc_server_init, hence
7139 the server starts listenning as soon as it is run, even if it
7140 does not have connections to other routers. Let's see how well
7143 * Changed default connection retry timeouts for more suitable in
7146 * Removed cipher and such arguments from silc_idlist_add_client
7147 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7148 Added new function silc_idlist_add_data to add the keys and stuff
7151 * Added SilcIDListData structure and added it to SilcClientEntry
7152 and SilcServerEntry as their first field in the structure. This
7153 way we can explicitly cast the ID entries to the SilcIDListData
7154 structure and get common data for the entries. In past, we had
7155 to first check what type of connection it is and then cast it to
7156 correct ID entry type. Now, we can directly cast the opaque
7157 pointer to the SilcIDListData (no matter what ID entry it actually
7158 is) and get the data needed.
7160 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7163 in some circumstances even if threre were timeout tasks, though not
7164 IO tasks, but tasks anyway. Now fixed.
7166 * Defined SilcServerConnection structure to hold connection specific
7167 stuff about directly connected servers and routers. The definition
7168 is currently in silcd/server_internal.h. I thought about having
7169 a bit more important role fro this struct but for now it is used
7170 only when connecting to other server (or router actually).
7172 * Added connecting retry support in server when connecting to
7173 router(s). The retry feature implement exponential backoff
7174 algorithm. Also, added SilcServerParams structure to hold default
7175 parameters for server. For now, it include these retry settings
7176 and are hard coded. After server is moded to be as Silc Server
7177 Library this structure will be more important.
7179 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Changed client librarys channel->clients table to SilcList and
7182 changed code accordingly.
7184 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7186 * Changed client's channel table to SilcList and changed code
7187 accordingly. Also changed SilcChannelClientEntry to include back-
7188 pointer to the channel so that client entry can use that structure
7189 as list as well and we have fast cross-reference to the channel.
7190 This change dramatically decreased the complexity of channel
7191 handling with client entry and vice versa (removed one extra
7192 loop when searching for channel entry from many functions).
7194 * Changed server->sim from table to SilcDList and changed code
7197 * NAMES command can now be used from user interface. It will show
7198 the user list on the channel, neatly.
7200 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7201 Code now saves realname of the user if it becomes available.
7203 * Renamed configure.in to configure.in.pre and made ./prepare
7204 script to automatically add correct version string to
7205 configure.in which it creates from configure.in.pre.
7207 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7209 * NAMES command reply now shows users mode with the nickname when
7212 * Moved silc_client_ch[u]mode[_char] functions from
7213 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7214 place sucks, they are utility functions and should be in some
7217 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7219 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7222 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7226 * Added TRQ (efficient deque and list library) into lib/trq. This is
7227 a very good list library that is currently used in the SILC. Defined
7228 SilcList API over the library because I didn't like the API very
7229 much. See lib/trq/silclist.h for the API and examples of how to
7230 use the API. Fixed various places in the code to use the new
7231 SilcList API. The SilcList is meant for lists that has a structure
7232 already defined as a list. It is not suitable to add just some
7233 context to the list (in TRQ, the context is the list actually).
7235 So, I defined SilcDList that can be used for the purpose where
7236 predefined list structure does not exit. This can be used as
7237 such list. Now some context just can be added to the SilcDList.
7238 Currently this list is not used in the SILC just yet, though there
7239 are a lot places where this can replace dynamically allocated
7240 tables and I will fix these places, later, to use SilcDList.
7241 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7242 and use TRQ internally).
7244 Also fixed some annoying warning messages that the original TRQ
7245 code generated. Also minor changes to TRQ's Makefile.in.
7247 * Added support for querying by Client ID to both WHOIS and
7248 IDENTIFY commands into server, as required by the protocol.
7250 * Removed method function pointers from SilcBuffer structure. They
7251 weren't used to anything and just increased the context size for
7252 no good reason. This change also made silc_buffer_alloc and
7253 silc_buffer_free functions inline functions.
7255 * Disabled command flooding detection support until it's fixed so
7256 that it accepts commands in but does not execute them more than once
7259 * Added silc_net_localhost(), to return local hostname, into
7260 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7261 that must be initialized before calling silc_client_init.
7263 * Added new function: silc_server_send_notify_on_channels to send
7264 notify messages to all channels client has joined. It is assured
7265 that the message is sent only once per client.
7267 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7268 lib/silcutil/silcutil.[ch] as silc_format function. The new
7269 function is generic and is used by server as well, not only by
7270 the logging routines.
7272 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7273 the provided version string was not acceptable. Added new function:
7274 silc_ske_check_version into lib/silcske/silcske.h. The function
7275 must be implemented by the application (client or server) and it
7276 does not reside in the SKE library. The function checks the version
7277 string remote end sent.
7279 * Added back pointers (to opaque context and to SilcSocketConnection)
7280 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7282 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7283 duplicate packet context structure.
7285 * Changed `notify' client operation to send same arguments as client
7286 receives from server except for ID's. ID's are mapped to correct
7287 ID entry and that is returned. Also, if channel entry is not sent
7288 by server but the notify is for channel the channel entry is sent
7289 to application (otherwise application doesn't know that it is for
7290 channel (library gets it from packet's Destination ID)).
7292 * Added silc_client_remove_from_channels into client library to
7293 remove a client from all channels it has joined to. Used when
7294 received SIGNOFF notify from server. Added also new function
7295 silc_client_replace_from_channels to replace old ID entry with
7296 new ID entry on all channels. Used when received NICK_CHANGE
7299 * Fixed ID Cache list handling in silc_idlist_get_client in
7300 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7301 to get (or query) client by ID.
7303 * Updated TODO list.
7305 * Added connection authentication status message defined by the
7306 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7307 support for these into the code in client and server side.
7309 * Added generic function silc_client_send_command to send any command
7310 with variable argument list. Application should use this function
7311 to send commands if the command functions provided by the library
7312 does not suite for the application's user interface needs.
7314 * Added new `failure' client operation. Application is notified about
7315 received failure packet if client is executing a protocol. In this
7316 case the protocol's execution has failed.
7318 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7319 is required by the protocol.
7321 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7322 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7325 * Added status flag to SilcSKE object to indicate realtime status
7326 of the SKE protocol.
7328 * Application receives now exactly same command reply arguments as
7329 the library receives from server. However, if ID is received the
7330 corresponding ID entry is returned to the application (eg. Client
7331 ID is mapped to correct SilcClientEntry entry and that is returned).
7332 Changed command_reply client operation due to this change.
7334 * Changed all ID's in commands and in command replys as ID Payloads.
7335 Change affected both client and server side codes.
7337 All ID's sent in SILC network (with execption of ID's in SILC
7338 Packet header) are sent in ID Payload to support variable length
7341 * Server now notifies nick changes and notifies all clients on
7342 the channels about the new nickname (about the new Client ID,
7345 * Implemented CMODE command to change channel modes. Supports all
7346 channel modes defined by the protocol specs except ban and invite
7347 lists. (Also, private channel key mode is supported but support for
7348 setting private channel key in client is missing, thus, this mode
7349 has no effect on client side (except that server requires that the
7350 client uses private channel key and normal channel traffic does not
7353 Also, invite mode works per se, but INVITE command does not work
7354 yet correctly, so you can set channel as invite only channel but
7355 inviting clients to the channel does not work (it is yet to be
7356 thought what's the best way to do it).
7358 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7359 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7360 Implemented CUMODE command to change user's mode on the channel.
7361 Supports all modes defined by the protocol specs.
7363 * Added NAMES command reply to return users modes on the channel.
7365 * Removed unnecessary and slow ciphers from lib/silccrypt.
7367 * Set SO_KEEPALIVE option to connection sockets by default.
7369 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7371 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7372 redefined the Notify Payload into protocol specs.
7374 * Added silc_id_payload_parse_id to get ID directly from raw
7377 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7379 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7380 accept searching by Client ID as well.
7382 * Added support for LEAVE and SIGNOFF notify types in client library.
7384 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7385 to parse ID Payload from raw data.
7387 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Added flags parameter into silc_ske_assemble_security_properties
7390 function in lib/silcske/silcske.[ch].
7392 * Changed notify client operation to fit better for notify messages
7393 sent by server. The notify payload received from server is now
7394 passed to the application (after parsing it to SilcNotifyPayload).
7395 It is application's responsibility to retrieve the arguments
7396 from the payload and show the message the way it wants. The message
7397 sent by server is implementation specific.
7399 * Changed public keys to comply with the protocol specification.
7400 Old public keys are not supported anymore and are not compatible.
7402 * Removed nickname from Channel Payload as the latest draft removed
7403 it. The client must resolve the nickname from the NAMES command
7404 reply received when it joined the channel.
7406 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7408 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7410 * Fixed some errors in protocol specification drafts.
7412 * Created lib/silccore/silcnotify.c to implement Notify Payload
7413 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7414 generic payloads described by protocol specifications. The file
7415 includes implementations for ID Payload and Argument Payload.
7417 * Changed Command Payload implementation to use the new Argument
7418 Payload. Changed command_xxxx_payload to command_payload_xxxx
7419 to comply with SILC coding conventions.
7421 * Added suppport for Argument Payload handling in Notify Payload
7422 implementation as protocol requires it. Added the new support
7423 into server and client lib as well.
7425 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7427 * Added support for multiple nicknames on same channel. [n] is
7428 added locally to the nickname if there are more than one same
7429 nicknames on the channel.
7431 * Server now sends all nicknames that matched WHOIS request.
7432 Client also shows the list received from server.
7434 * Added TOPIC command to client side. User can now set and show
7435 current topic on channel.
7437 * Added MOTD command to client and server. Also, server sends the
7438 motd when client connects to the server.
7440 * Changed version strings to comply ISO 8601.
7442 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Fixed protocol error handling in client library. It should now
7445 cope even if the SKE fails for some reason.
7447 * Made new protocol specification drafts for submitting to IETF.
7449 * Implemented TOPIC command to server in silcd/command.c.
7451 * Added two new notify types into lib/silccore/silcnotify.h:
7452 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7453 notify nickname change and topic setting/change on a channel.
7455 * API change of command_reply operation in client library. The
7456 application gets now the status type received from server as well.
7458 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7462 * Cras fixed and optimized the packet handling even further and
7463 it should work now. Minor change to the prototype of function
7464 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7466 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Added new function into lib/silcutil/silcschedule.[ch]:
7469 silc_schedule_with_fd to select() a specified fd. The function
7470 returns after timeout expires or data arrives or goes. The
7471 function is used by packet routines to wait that all data is
7472 received from network.
7474 * Fixed data reading from network in lib/silccore/silcpacket.c.
7475 The code now assures that all data is read from the fd and then
7476 continues packet processing. This was a bug fix since the code
7477 used to drop some data in some circumstances.
7479 * Added new function into lib/silcclient/client.[ch]:
7480 silc_client_start_key_exchange to start key exchange after
7481 connection has been established to server. The code internally
7482 now uses this funtion but its main purpose was to provide it
7483 for applications that perform their own connecting. After
7484 application has created a connection it merely calls this
7485 function to start the key exchange between client and server.
7486 The library takes care of everything else after that.
7488 Updated also lib/silcclient/README to explain the usage of
7491 * Do not send to application information that connection has
7492 been established. Application gets notified it by connect
7495 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Applied cras's patch to add silc_schedule_one function. The
7498 function runs scheduler once and returns.
7500 * Fixed the scheduler after cras messed it up. The timeout
7501 handling works now as it's supposed to work.
7503 * Added into lib/silccore/ silcnotify.h to include notify
7504 message types support. Changed silc_server_send_notify*
7505 functions, in server.[ch], to support those new notify types.
7506 Added the support for the notify types into client library,
7507 as well. Added new notify client operation into ops.h in
7510 * Changed silc_server_packet_send_to_channel to send normal
7511 packets instead of just channel message packets. The function
7512 is now used to send the notify packets to channels. It is not
7513 used to send channel message packets anymore, as server never
7516 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7517 va_arg()s as it seems to require it nowadays. I guess, if SILC
7518 is compiled with older va_arg() the new code should work anyway.
7520 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7522 * Splitted core library. Core library (lib/silccore) includes
7523 now only SILC protocol specific core (and common) components.
7524 Created new utility library (lib/silcutil) that includes more
7525 generic purpose stuff. The stuff for util library was taken
7526 from the old core library. This was minor and easy split.
7528 * Created SILC Client Library (lib/silcclient) that includes
7529 implementation of the SILC client without user interface. This
7530 was major move from silc/ directory. The code has been changed
7531 so that it is transparent towards the user interface. The
7532 silc/ directory includes now the same user interface as before
7533 and it uses the new client library. Read lib/silcclient/README.
7534 Basicly, the client library performs everything else related
7535 to SILC except user interface handling. Also, configuration
7536 files are considered to be part of user interface and library
7537 does not handle them.
7539 This change also changed a lot of structures, function naming etc.
7540 Most important change was that SilcClientWindow object was
7541 renamed to SilcClientConnection in the client library. Created
7542 also new file lib/silcclient/ops.h. Also added new files
7543 silc/local_command.[ch] and silc/client_ops.[ch].
7545 All these changes were made to make it easier for user interface
7546 designers to create what ever user interface for the SILC client
7549 It is also expected that the server will be moved to lib
7550 directory as well and SILC Server Library will be created;
7551 sometimes in the future.
7553 * Removed Local commands from lib/silccore/silccommand.h as
7554 they are application specific and new client library does not
7555 handle any of those anymore.
7557 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7558 old client implementation in silc/.
7560 * Added support for callback functions in SILC_LOG_* macros.
7561 Application can now set its own callbacks that will be called
7562 instead of using the default functions that will always print
7563 the debug messages to stderr (or stdout). Also, debugging can
7564 now be disabled by setting silc_debug to FALSE and re-enabled by
7565 setting it to TRUE. Note, that logging will still work even
7566 if debugging is disabled.
7568 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7569 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7570 silc_log_reset_debug_callbacks.
7572 * To enable debugging in silc client one must give now -d
7573 option on command line.
7575 * Changed silc_schedule_init to automatically allocate task queues
7576 if they are not allocated before calling it.
7578 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7580 * Added GMP 3.1 into math library.
7582 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7584 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7585 a channel in SILC network. The packet is used by servers and
7586 routers to notify other routers that user has left a channel.
7587 This little feature was missing until now. Added the feature
7588 to protocol specification as well.
7590 Added functions: silc_server_send_remove_channel_user and
7591 silc_server_remove_channel_user into server.[ch].
7593 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7594 lib/silccore/silcpacket.h. However, they are not implemented
7597 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7599 * Fixed joining to a channel and sending channel messages
7600 between server and router. The channel message sending should
7601 now work inside a cell.
7603 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7605 * Fixed the private message sending between server and router.
7606 The private message sending should now work inside a cell.
7608 * Added silc_server_replace_id into server.[ch] to replace
7609 existing ID in the SILC network.
7611 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7612 and silc_idlist_replace_server_id into idlist.[ch] in server.
7614 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7616 * Fixed the server to server connections. Server can again now
7617 connect to router. Router to router connections probably does
7620 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7622 * Added dynamic protocol registering support. Now protocols can
7623 registered and unregistered on the fly. Patch by cras.
7625 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7627 * Added lib/contrib directory to hold routines that some platforms
7628 don't have but are needed by SILC.
7630 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7631 into lin/contrib to provide getopt() and getopt_long() for
7632 those who don't have it.
7634 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Added AWAY command to client. When away message is set and
7637 client receives a private message packet the client automatically
7638 replies to the sender with the away message.
7640 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7641 bug seemed to be the cause of recent problems when compiling
7644 * Added version detection support to SKE protocol specification
7645 and added the new changes to the SKE implementation as well.
7646 There were other minor changes in the SKE protocol as well.
7648 Many changes in lib/silcske/silcske.[ch] and in
7649 lib/silcske/payload.[ch].
7651 * Added ^U functionality, clear input line. Patch from cras.
7653 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7655 * Mainly small bugfixes on core library. Fixed some debugging
7656 logging and buffer overflow in silclog.c.
7658 * Updated config.sub and config.guess on the distribution tree.
7660 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7662 * Added command lagging support in server. Client may execute
7663 commands now only once in two seconds.
7665 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Optimized packet reception. MAC computation and checking is now
7668 also more optimized. A lot previously duplicated code is now
7669 used as generic by both client and server.
7671 * Fixed key pair generation in clientutil.c
7673 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7675 * Added into lib/silccore/silcbufutil.[ch] new function;
7676 silc_buffer_realloc.
7678 * Moved generic packet sending/encryption functions to
7679 lib/silccore/silcpacket.[ch] from client and server. Some
7680 rewriting of the functions.
7682 * Moved all generic packet reception/decryption functions to
7683 lib/silccore/silcpacket.[ch] from client and server. The
7684 packet processing is now much cleaner in both client and server.
7685 These were major changes in both client and server.
7687 * Created many common functions in server to do packet sending.
7688 Previously code were duplicated a lot, this has been removed
7691 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7693 * Rewrote major parts of the ID cache system. Don't know
7694 whether it is better now or not but at least the API is more
7697 * Major rewrite on ID cache stuff on client because of the ID
7698 cache API changes. Added idlist.c to client.
7700 * Also major rewrite on ID cache stuff on server as well.
7701 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7702 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7703 in hand, instead they are all put into the ID cache system now.
7704 All server_idlist_* routines uses ID cache now instead of
7705 traversing its own lists (those lists does not exist anymore).
7706 SilcIDList though still exists. Also, SilcXXXEntry's are
7709 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Finally made the SKE implementation compliant to the protocol
7712 specification. All mp integers are now binary encoded as
7713 opposed being HEX encoded.
7715 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7718 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7719 functions: silc_[encode/decode]_pem. Also added function
7720 silc_encode_pem_file to PEM encode with newlines ('\n') for
7723 * SILC public keys are now encoded either PEM or binary. Same
7724 option is for private keys as well. By default private keys
7725 are binary encoded and public keys PEM encoded. Silly HEX
7726 encoding were removed.
7728 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7729 function to create fingerprints.
7731 * Fixed a bug in SHA1; does not change the original data anymore.
7733 * Partly implemented INFO command on client and server side.
7734 Fixed CLEAR command. Changes to SERVER command; show current
7735 server(s) when giving command without arguments. Added
7736 VERSION command to client.
7738 * Added check to server that unregistered connections cannot
7739 execute commands (unless it is specificly allowed).
7741 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7743 * Fixed screen refresh.
7745 * Fixed channel joining bug from client. On some circumstances
7746 client tried to join to a channel it had already joined.
7748 * Added public key verification process into client's protocol.c.
7749 The client now verifies the public key from user and saves
7750 it into ~./silc/serverkeys/ directory.
7752 Added into: clientutil.[ch]: silc_client_verify_server_key.
7754 * Changed SKE protocol's silc_ske_initiator_finish function
7755 to accept callback function that verifies the received public
7756 key. Removed old silc_ske_verify_public_key function.
7758 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7761 silc_pkcs_private_key[_data]_set.
7763 * Made the password and public authentication more cleaner in
7764 server's protocol.c.
7766 * Removed historic and obsolete protocol `channel_auth' from
7767 both client and server.
7769 * Removed wrong way of sending command status messages from
7770 server to client in server's command.c. The old way violated
7771 protocol specification.
7773 Changes to silccore/silccommand.[ch]: removed
7774 silc_command_encode_status_payload -> not needed anymore,
7775 changed silc_command_encode_payload_va to accept extra
7776 argument on variable argument list. The argument type must
7777 now be provided to the function. Also, added new function:
7778 silc_command_encode_reply_payload_va which is same as
7779 normal command_encode_payload_va except command status type
7780 is provided as extra argument.
7782 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Added ~./silc directory handling. The directory includes the
7785 public and private keys for the client.
7787 Added silc_client_check_silc_dir, silc_client_create_identifier
7788 and silc_client_load_keys.
7790 * Implemented SILC protocol compliant public key. Added public
7791 and private key saving to and loading from files.
7793 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7794 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7795 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7796 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7797 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7799 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7800 silc_pkcs_load_[public/private]_key.
7802 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7804 * Added silc_server_get_route (route.[ch]) to get connection
7805 data for the fastest route for given ID.
7807 * Implemented INVITE command on client and server. The command
7808 were re-defined in the SILC Protocol Specification and the
7809 implementation now complies with the specification.
7811 * Implemented PING command on client and server.
7813 * Implemented NAMES command on client and server. The server side
7814 supports currently only normal server not router server yet.
7815 Some changes to NAMES definition in SILC protocol specification.
7817 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7819 * Implemented LEAVE command on client and server.
7821 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7822 again. This change was made to the protocol as well. Server
7823 should not violate the protocol specification anymore.
7825 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7827 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7828 was tested. SOCKS4 was not but should work anyway.
