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

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

793 algorithm parts and created new file silcalgs.conf, that
794 is now included from the example_silcd.conf.in.
796 * Optimized the silc_server_connect_to_router_second to take
797 the connection configuration object from the SilcServerConnection
798 object instead of finding it during the connecting phase.
799 Added the configuration object to SilcServerConnection struct.
800 Affected files silcd/server_internal.h, server.c.

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

885 zero port also if the hostname is NULL because it could not
888 Call file transfer monitor callback now also if error occurs
889 during key agreement protocol.
891 Changed the silc_client_file_send interface to return the
892 SilcClientFileError instead of session id. The session ID
893 is returned into pointer provided as argument.

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

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

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

989 lists correctly. Affected file silcd/command.c.
991 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * When sending JOIN command to router for processing the
994 sender's old command identifier was not saved back to the
995 sender's command context, fixed now. The affected file is
998 * Create the key in JOIN command of the router did not return
999 the channel key, added check for this. Affected file is
1002 * Fixed a channel ID update bug in JOIN command reply. Do
1003 not directly upgrade the ID but call the function
1004 silc_idlist_replace_channel_id if the ID was changed.
1005 Affected file silcd/command_reply.c.
1007 * Fixed memory leaks from command calling if it would fail.

1035 functions. Affected file silcd/server.c.
1037 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1038 which ID was changed. This way the router will send the
1039 user list for the channel again, and server won't be in
1040 desync in some rare circumstances. Affected file is
1041 silcd/packet_receive.c.
1043 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1083 key exchange. Affected file silcd/server.c.
1085 * Do not reconnect on connection failure when SCONNECT was
1086 given. Affected files silcd/server.[ch].
1088 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1092 * Fixed the NICK command to always give the unformatted
1093 nickname to the one giving the NICK command. If unformatted
1094 nickname is cached already it will be formatted and the
1095 local entry will always get the unformatted nickname.
1096 Affected file lib/silcclient/idlist.c.
1098 * Fixed some double frees from client library commands.
1099 Affected file is lib/silcclient/command.c.
1101 * Fixed CUMODE command in server to assure that no one can
1102 change founder's mode than the founder itself, there was a
1103 little bug. Affected file silcd/command.c.
1105 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * Removed the SilcClientCommandDestructor from the client
1108 libary, it is not needed anymore. Affected files are
1109 lib/silcclient/silcapi.h, command[_reply].[ch],
1110 client_notify, idlist.c.
1112 * Fixed GETKEY command to first resolve client, and then
1113 resolve the server only if the client was not found, instead
1114 of resolving both at the same time. Affected file is
1115 lib/silcclient/command.c.
1117 * Added silc_client_start_key_exchange_cb and lookup the
1118 remote hostname and IP address before starting the key
1119 exchange with server. The affected file is
1120 lib/silcclient/client.c.
1122 * The server's public key is now saved using the IP address
1123 of the server and not the servername for the filename.
1124 The hostname public key filename is checked as an fall back
1125 method if the IP address based filename is not found.
1127 Fixed the GETKEY command to save the fetched server key
1128 in correct filename.
1130 Print the remote server's hostname now when new key is
1131 received during connection process. Affected file is
1132 irssi/src/silc/core/client_ops.c.
1134 * Return always our own public key to the client if it asks
1135 for it with GETKEY command. Affected file silcd/command.c.
1137 * Removed the use_auto_addr variable from default config
1138 file since it was in wrong section. Affected file is
1141 * Fixed TOPIC_CHANGE notification to not route it when it
1142 was sent using silc_server_send_notify_to_channel function.
1143 Affected file silcd/command.c.
1145 * Fixed silc_server_send_notify_kicked to send the kicker's
1146 Client ID also, it was missing. Affected files are
1147 silcd/command.c, silcd/packet_send.[ch].
1149 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1151 * Do not save client history information in SERVER_SIGNOFF.
1152 Fixes the bug in normal server that it does not detect
1153 the client becoming valid after the server becomes back
1154 online. Affected file silcd/server_util.c.
1156 * Added `sock_error' field into the SilcSocketConnection
1157 context. When error occurs during socket operation (read
1158 or write) the error is saved. Added also new function
1159 silc_socket_get_error to return human readable socket error
1160 message. Affected files are lib/silcutil/silcsockconn.[ch],
1161 lib/silcutil/unix/silcunixsockconn.c, and
1162 lib/silcutil/win32/silcwin32sockconn.c.
1164 * The server now prints the socket error message in the
1165 signoff for client. Affected file silcd/server.c.
1167 * Fixed the `created' channel information sending from router
1168 to server in JOIN command. Checks now whether the channel
1169 really was created or not and set it according that.
1171 Fixed the JOIN command to use the client entry's current
1172 ID during the joining procedure instead of the one it sent
1173 in the command (it is checked though), since it can change
1174 between the packet processing and command processing, and
1175 would just case unnecessary pain in the client end. Affected
1176 file silcd/command.c.
1178 * Fixed a channel key payload sending to use correct channel
1179 ID when the server was forced to change the channel's ID by
1180 router. Router sent the key payload with the old Channel ID.
1181 Affected file silcd/packet_receive.c.
1183 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Call silc_server_save_channel_key only if the key payload
1186 was provided in the JOIN command's command reply. Affected
1187 file silcd/command_reply.c.
1189 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed silc_mp_sizeinbase to return the value correctly with
1192 MPI. Affected file lib/silcmath/mp_mpi.c.
1194 * Fixed the stop_server signal to correctly stop the scheduler
1195 and gracefully stop the server when SIGTERM or SIGINT signals
1196 are received. Affected file silcd/silcd.c.
1198 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1200 * Simple handling of TERM and HUP signals. Also added some log
1201 flushing call around. Affected file is
1204 * Fixed small bugs in silclog.c. Now buffering output will take
1205 effect after 10 seconds since startup: This will ensure that
1206 no important startup messages are lost. Also output redirection
1207 will preserve original format ([Date] [Type] message).
1208 Affected file is lib/silcutil/silclog.c.
1210 * Added two options to the config file, in the logging section:
1211 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1212 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1214 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1216 * Do not print the warning about log files not being initialized
1217 more than once to avoid excess logging. Affected file is
1218 lib/silcutil/silclog.c.
1220 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1221 the SIM copying in make install in Makefile.am.pre.
1223 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1225 * Rewritten silclog APIs. Globally interesting changes follows:
1226 silc_log_set_files() changed to silc_log_set_file().
1227 silc_log_set_callbacks() changed to silc_log_set_callback().
1228 ROBOdoc documented silclog header file.
1229 SilcLogCb now returns bool to wether inihibit the default
1230 handler or not (to keep the old behaviour return always TRUE).
1231 The new APIs should also fix the problem of the
1232 silcd_error.log file that was written in the current directory.
1235 Log files streams will remain opened after silc_log_set_file()
1236 call, means less CPU usage notably on high traffic servers.
1237 File streams are now full buffered, and flushed to the disk
1238 every 5 minutes, lesses HD activity and CPU usage.
1239 Messages can be redirected, allowing admins to configure
1240 one single logfile for all server messages.
1241 the silc_log_quick global variable to activate fast-logging.
1242 Affected files lib/silcutil/silclog.[ch]
1244 * Changed some code to conform new silclog APIs. Affected
1245 files are doc/example_silcd.conf.in, silcd/server.c
1246 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1249 * Fixed a memory leak that could occur in some situations.
1250 Affected file silcd/serverconfig.c.
1252 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * Added the silc_client_del_client to remove the client from
1255 all channels as well. Affected file lib/silcclient/idlist.c.
1257 * Fixed the client library to correctly remove the client
1258 from all channels when the client entry is being destroyed.
1259 Affected file lib/silcclient/client_notify.c, command.c.
1261 * Added auto-nicking support to the client library. If the
1262 applicatio now sets client->nickname it will be sent to the
1263 server after connecting by the library. This way for example
1264 SILCNICK (or IRCNICK) environment variables will have effect
1265 and always change the nickname automatically to whatever
1266 it is wanted. Affected file lib/silcclient/client.[ch].
1268 * Renamed silc_server_command_bad_chars to the
1269 silc_server_name_bad_chars and moved it to the
1270 silcd/server_util.[ch]. Added also new function
1271 silc_server_name_modify_bad to return nickname that
1272 includes bad characters as new nickname without those
1273 bad characters. This check and modify is now used in
1274 silc_server_new_client when the username is initially set
1275 as nickname, so it must be checked to be valid nickname.
1276 Affected file silcd/packet_receive.c.
1278 * The nickname length is now taken from the packet for real
1279 and not trusted to strlen() since it clearly can return
1280 wrong length for nickname including bad characters. This
1281 also applies to channel names. Affected file silcd/command.c.
1283 * Removed the lib/silcsilm/modules directory. Modules are now
1284 compiled into the lib/silcsim. Fixed the copying of the
1285 modules to follow symbolic links in Makefile.am.pre.
1287 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1289 * Fixed silc_string_regexify list creation. Fixes bugs with
1290 BAN and INVITE commands in server. The affected file is
1291 lib/silcutil/unix/silcunixutil.c.
1293 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Removed the command destructor entirely from the server's
1296 command and command reply routines. It is not needed, and
1297 its usage was buggy and caused crashes. Affected files are
1298 silcd/command[_reply].[ch].
1300 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Cancel protocol and NULL sock->protocol if timeout
1303 occurred during protocol. Affected file silcd/server.c.
1305 * Cancel protocol timeouts always before calling the final
1306 callback, to assure that after final callback is called
1307 no other state will be called for the protocol anymore.
1308 Affected file silcd/protocol.c.
1310 * Print error log if incoming connection configuration could
1311 not be found. Affected file silcd/server.c.
1313 * Fixed JOIN command to correctly save the founder mode
1314 to the client on normal SILC server, when the channel
1315 was created by the router. Affected file silcd/command.c.
1317 * Fixed LIST command (hopefully) to send correct reply
1318 packets. Affected file silcd/command.c.
1320 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * The silc_packet_receive_process now returns FALSE if the
1323 read data was invalid packet, and TRUE if it was ok.
1325 The server now checks that if unauthenticated connection
1326 sends data and its processing fails the server will close
1327 the connection since it could be a malicious flooder.
1329 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1331 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1333 * Make sure the warning about error opening a log file is
1334 printed only once and not everytime it fails (produces
1335 too much useless log). Affected file lib/silcutil/silclog.c.
1337 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1339 * Made the silc_server_daemonise() function more readable.
1340 Affected file silcd/server.c.
1342 * Pid file is now optional, the user may comment it out from
1343 the config file. Removed define SILC_SERVER_PID_FILE, we
1344 don't need a default any longer. Affected file
1345 configure.in.pre, lib/Makefile.am.pre.
1347 * Make some use of the pid file. The server now dies at startup
1348 if it detects a valid pid file on his path. The server would
1349 die anyway in this circumstance, because of the bind() failure.
1350 Affected file silcd/silcd.c.
1352 * No longer compiling lib/dotconf.
1354 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Fixed JOIN command parsing not to crash. Affected file
1357 lib/silcclient/command.c.
1359 * Fied the NICK_CHANGE notify to add the new client entry
1360 even it is resolved. This removes an <[unknown]> nick
1361 thingy bug in the client. Affected file is
1362 lib/silcclient/client_notify.c.
1364 * Do not try to allocate 0 bytes (efence does not like it)
1365 in lib/silccore/silccomand.c when encoding payload.
1367 * Do not take IRCNICK as nickname in Irssi SILC client since
1368 it is not possible to set nickname before hand connecting
1369 the server (TODO has an entry about adding auto-nicking
1372 * Changed the silc_server_command_pending to check whether
1373 there already exists an pending entry with the specified
1374 command, command identifier and pending callback. This is
1375 to fix IDENTIFY and WHOIS related crashes that may register
1376 multiple pending commands with same identifier. Affected
1377 file silcd/command.c.
1379 * Fixed the server to reconnect to the router even if it
1380 was already reconnecting and EOF was received. This to
1381 fix a possibility that the server wouldn't ever try to
1382 auto-reconnect to the router. Affected file silcd/server.c.
1384 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Fixed the server's password authentication to use the
1387 length of the locally saved password, and not the one
1388 sent in the packet. Affected file silcd/protocol.c.
1390 * Fixed same password authentication problem in the
1391 Authentication Payload handling routines in
1392 lib/silccore/silcauth.c.
1394 * Yet another password authentication problem fixed with
1395 channel password handling in silcd/command.c.
1397 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * If first character of string in silc_parse_userfqdn is '@'
1400 then do not parse it. Affected file is
1401 lib/silcutil/silcutil.c.
1403 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Fixed minor bug in IDENTIFY command reply sending, which
1406 caused various weird problems during JOIN when it was
1407 resolving names for users. Affected file silcd/command.c.
1409 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Fixed the IDENTIFY command reply sending to chech better valid
1412 clients. It was possible to send incomplete list of replies.
1413 Affected file silcd/command.c.
1415 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Added silc_client_command[s]_[un]register functions now to
1418 dynamically register the commands in client library. Removed
1419 the static table of commands. This allows the client library
1420 to call commands without causing the application to know about
1421 what commands library has called.
1423 Removed the INFO command reply kludge to detect when the command
1424 was called by library. Now library use its own command reply
1425 function for INFO command.
1427 Added function silc_client_command_call to call a command.
1428 Application can use it to call command, not access the structure
1431 Now all commands that are sent by the client library (not
1432 explicitly sent by application) use own command reply functions.
1434 Affected files around lib/silcclient/ and in
1435 irssi/src/silc/core/.
1437 * Fixed the WHOIS command reply sending to chech better valid
1438 clients. It was possible to send incomplete list of replies.
1440 Fixed the WHOIS and IDENTIFY to send the request to router
1441 if normal server did not do it and did not find any results.
1443 Affected file silcd/command.c.
1445 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Moved the internal data from SilcClient context into its
1448 own file, not accesible to application. Affected files
1449 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1450 and other files in client library.
1452 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * Added doc/examples installation target in Makefile.am.pre.
1457 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1460 commands the found client entry will be removed from the
1461 cache, after notifying application about the error. Affected
1462 file lib/silcclient/command_reply.c.
1464 * Changed the /MSG to check for exact nickname user gave, and
1465 not let `nick' match `nick@host' if it is only one found. Now,
1466 user must type the exact nickname (like nick@host2) even if
1467 there are no more than one same nicks found. This is to avoid
1468 a possibility of sending nickname to wrong nickname since
1469 `nick' could match `nick@host'. Affected file is
1470 irssi/src/core/silc-servers.c.
1472 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Do not print "you are now server operator" or similar when
1475 giving /away command. Affected files are
1476 irssi/src/silc/core/client_ops.c, silc-servers.h.
1478 * Made the silc_server_command_pending_error_check to send
1479 the same command reply payload it received back to the
1480 original sender of the command. This way all arguments
1481 that was received by the server will be received by the
1482 client too. Affected file silcd/command.c.
1484 * Added the silc_idcache_add to return the created cache entry
1485 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1487 * Add global clients to expire if they are not on any channel.
1488 This is because normal server will never know if they signoff
1489 if they are not on any channel. The cache expiry will take
1490 case of these entries. This is done by normal servers only.
1491 The affected files are silcd/command_reply.c,
1492 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1494 * If server receives invalid ID notification for WHOIS or
1495 IDENTIFY and the ID exists in the lists, it is removed.
1496 Affected file silcd/command_reply.c.
1498 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1499 in client then client entry that it matches is searched and
1500 the nickname is printed on the screen for user. Affected
1501 file irssi/src/silc/core/client_ops.c.
1503 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Use cache entry expire time in the LIST command reply to
1506 purge old entries from the cache after the LIST command
1507 reply has been received. This way we don't have non-existent
1508 entries in the cache for too long. Affected file is
1509 silcd/command_reply.c.
1511 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * If we are normal server, and we've not resolved client info
1514 in WHOIS or IDENTIFY from router, and it is global client,
1515 we'll check whether it is on some channel. If it is not
1516 then we cannot be sure about its validity and will resolve it
1517 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1518 file silcd/command.c.
1520 * Search channel by name (if possible) rather than by ID
1521 in IDENTIFY command's command reply. Affected file is
1522 silcd/command_reply.c.
1524 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1527 Updated specs and implemented it. Affected file silcd/command.c,
1528 silcd/packet_send.c and silcd/packet_receive.c.
1530 * Implemented the <founder auth> payload handling in the JOIN
1531 command. If provided all conditions for channel joining
1532 except requirement to provide correct passphrase can be
1533 overrided by the channel founder. Updated the protocol specs.
1534 Affected file silcd/command.c.
1536 Added support for founder auth in JOIN command in client
1537 library. Fixed the parsing of the JOIN command now to support
1538 all options as they should be. The affected file is
1539 lib/silcclient/command.c.
1541 * Optimized the WHOIS and IDENTIFY commands to send the request
1542 to router only if it includes nicknames or other names. If
1543 they include only IDs then check the local cache first before
1544 routing. Affected file is silcd/command.c.
1546 * Added channels topic announcements. Affected file is
1547 silcd/packet_receive.c and silcd/server.c.
1549 * Fixed the silc_server_send_notify_topic_set to really destine
1550 the packet to channel. Affected file silcd/packet_send.c.
1552 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1553 library. Affected file lib/silcclient/client_notify.c.
1555 * Added UMODE announcements. Affected file silcd/server.c.
1557 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Memory leak fixes in:
1561 lib/silcutil/silcsockconn.c
1562 lib/silcske/silcske.c
1563 lib/silcske/groups.c
1565 lib/silccrypt/silcpkcs.c
1566 lib/silccore/silccommand.c
1567 lib/silccore/silcidcache.c
1572 * ROBOdoc documented the lib/silcske/groups.h file and a
1573 bit changed the interface for better.
1575 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1577 * Update the client entry context in the ID cache after
1578 nick change. Affected file lib/silcclient/command.c.
1579 Fixes the CUMODE command when regaining founder privileges,
1580 and a little WHOIS problem.
1582 * Fixed silc_net_gethostbyname to correctly call the
1583 inet_ntop. Affected file lib/silcutil/silcnet.c.
1585 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1587 * Added IPv6 support checking to the configure.in.pre, added
1588 also --enable-ipv6 option to override the check. Affected
1589 file configure.in.pre.
1591 * The silc_thread_create now calls the start function
1592 directly if threads support is not compiled in. Removes
1593 ugly #ifdef's from generic code. Affected files are
1594 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1596 * Added silc_net_gethostby[name/addr]_async to asynchronously
1597 resolve. Affected files are lib/silcutil/silcnet.[ch].
1599 * Added support for rendering IPv6 based server, client and
1600 channel IDs. Affected file lib/silcutil/silcutil.c.
1602 * Added support for creating IPv6 based server IDs. Affected
1603 file is silcd/serverid.c.
1605 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1607 * Added silc_net_gethostby[addr/name] into the
1608 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1609 routines. Added silc_net_is_ip[4/6]. Affected file is
1610 lib/silcutil/unix/silcunixnet.c. All routines that take
1611 address as argument now supports both IPv4 and IPv6 addresses.
1613 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1615 * Fixed LIST command reply sending in server. Affected file
1618 * Server now sends the kicker's client ID in the KICK notify
1619 to the kicked client. Affected file silcd/command.c.
1621 * The client library now parses the kickers client ID and
1622 UI displays it. Affected files lib/silcclient/client_notify.c
1623 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1625 * Made all payload parsing function prototypes consistent.
1626 They all take now const unsigned char * and uint32 pair as
1627 the payload data instead of SilcBuffer. Changes all around
1628 the source tree. Other unsigned char* -> const unsigned char*
1629 changes around the tree as well.
1631 * Optimized SFTP client and server packet sending not to
1632 allocate new buffer for each packet but to recycle the
1633 first allocated buffer. Affected files are
1634 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1636 * Optimized the SFTP client to use SilcList instead of
1637 SilcDList for requests, because it is faster. Affected file
1638 is lib/silcsftp/sftp_client.c.
1640 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1641 into lib/silccore/silcid.[ch].
1643 Renamed silcpayload.[ch] into silcargument.[ch].
1645 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * If client entry is deleted with active key agreement
1648 session, abort the session.
1650 The silc_client_abort_key_agreement now calls the completion
1651 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1653 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1656 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1658 * Don't use __restrict in older GCC's. Affected file is
1659 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1661 * silc_net_localhost now attempts to reverse lookup the
1662 IP/hostname. Affected file lib/silcutil/silcnet.c.
1664 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1665 command. It can be used to gain founder privileges at
1666 the same time when joining the channel.
1668 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1669 kicker's client ID as well. Updated protocol specs.
1671 Defined that the server must send SILC_COMMAND_IDENTIFY
1672 command reply with error status to client who sent
1673 private message with invalid client ID.
1675 Updated the protocol specification.
1677 * Added silc_server_send_command_reply to send any
1678 command reply. Affected file silcd/packet_send.[ch].
1680 * Added silc_id_payload_encode_data to encode ID payload
1681 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1683 * The server now send IDENTIFY command reply with error
1684 status if client ID in private message is invalid. Affected
1685 file silcd/packet_receive.c.
1687 * Save the server key file with server's IP address in
1688 the filename instead of hostname. The affected file is
1689 irssi/src/silc/core/client_ops.c.
1691 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1696 * Added libtool support for compiling shared objects in
1697 lib/silcsim. Affected file configure.in.pre and
1698 lib/silcsim/Makefile.am. Original patch by cras.
1700 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Pid file configuration, and server's config file fixes
1703 patch by toma. Updated CREDITS file.
1705 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Fixed silc_client_channel_message to not try to decrypt
1708 the message twice if it resolved the destination client
1709 information. This could cause of dropping one channel
1710 message. Affected file lib/silcclient/client_channel.c.
1712 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1715 lib/silcclient/client.c. This function is used when the SILC
1716 Client is run under some other scheduler, or event loop or
1717 main loop. On GUI applications, for example this may be
1718 desired to used to run the client under the GUI application's
1719 main loop. Typically the GUI application would register an
1720 idle task that calls this function multiple times in a second
1721 to quickly process the SILC specific data.
1723 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1725 * Fixed silc_server_drop() for dropping the supplementary
1726 groups as well, this could cause a security hole on some
1729 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1734 * Write PID file after dropping privileges. Added -F option
1735 to run server on foreground. A patch by debolaz.
1736 Affected files silcd/server.c, silcd/silcd.c.
1738 * Fixed MOTD to return the MOTD file server name. Affected
1739 file silcd/command.c.
1741 * Added INFO command reply handling to the Irssi SILC Client.
1742 Affected file irssi/src/silc/core/client_ops.c.
1744 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Fixed the silc_idcache_list_* routines to really support
1747 the dynamic list. Fixes a crash. Affected file is
1748 lib/silccore/silcidcache.c.
1750 * Fixed the LIST command reply to really call LIST command's
1751 pending callbacks. Affected file silcd/command_reply.c.
1753 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Update conn->local_entry->nickname after giving NICK
1756 command. Affected file lib/silcclient/command.c.
1758 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1760 * Added the [pid] option to the silcd configuration file
1762 Affected files: serverconfig.[ch] and silcd.c
1764 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Save fingerprint in WHOIS command reply in server.
1767 Affected file silcd/command_reply.c.
1769 * Fixed NICK commands pending callback registration.
1770 Affected file lib/silcclient/command.c.
1772 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Use ++server->cmd_ident when sending commands in server,
1775 instead of random number. Affected file silcd/command.c.
1777 * Fixed GETKEY command reply to call actually GETKEY pending
1778 command callbacks. Affected file silcd/command_reply.c.
1780 * A bit stricter check for nicknames. Check for same nickname
1781 in NICK command also. Affected file silcd/command.c.
1783 * Do not call INFO command everytime client ID changes, only
1784 during first connecting. Affected file lib/silcclient/client.c.
1786 * Set the new nickname only after successful command reply for
1787 NICK command is returned by server. Affected file
1788 lib/silcclient/command.c.
1790 * Remove nicknames from nicklist during server_signoff notify.
1791 Should fix /NAMES bit more. The affected file is
1792 irssi/src/silc/core/silc-channels.c.
1794 * Added `fingerprint' field to the SilcIDListData in the
1795 silcd/idlist.h to hold the fingerprint of the client's
1798 Send the fingerprint of the client's public key in WHOIS
1801 Affected files silcd/command.c, and silcd/idlist.[ch].
1803 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1804 create fingerprint from given data.
1806 * Show the fingerprint of the client's public key in WHOIS.
1807 Affected files irssi/src/module-formats.[ch] and
1808 irssi/src/silc/core/client_ops.c.
1810 * Format the multiple same nicknames also during JOIN and
1811 NICK_CHANGE notifys. Affected file is
1812 lib/silcclient/client_notify.c.
1814 * Do not print error on screen for invalid private message
1815 payload since it can come if someone is sending private
1816 messages with wrong key. Affected file
1817 lib/silccore/silcprivate.c.
1819 * Fixed multiple concurrent /PING crash. Affected file
1820 lib/silcclient/command.c.
1822 * Changed the wrong ID encoding. All IP addresses must be
1823 in MSB first order in encoded format. They were encoded
1824 wrong and was in LSB format. Affected files are
1825 silcd/serverid.c, lib/silcutil/silcutil.c.
1827 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1829 * Call the `connect' client operation through the scheduler
1830 in case of error. Affected file lib/silcclient/client.c.
1832 * Call the `failure' client operation even if the error
1833 occurred locally during a protocol. Affected file is
1834 lib/silcclient/protocol.c.
1836 * Added support of sending LIST command to router from normal
1837 server. This way normal server can get list of all channels
1838 in the network too. Fixed the channel list sending in the
1839 server too. Affected files are silcd/command.c, and
1840 silcd/command_reply.[ch].
1842 * Added silc_server_update_channels_by_server and
1843 silc_server_remove_channels_by_server. They are used during
1844 disconnection of primary router and in backup router protocol.
1845 Affected file silcd/server_util.[ch], silcd/server.c and
1846 silcd/server_backup.c.
1848 * Fixed channel adding to global list in IDENTIFY command
1849 reply in server. Affected file silcd/command_reply.c.
1851 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * If the incoming packet type is REKEY or REKEY_DONE process
1854 that packet always synchronously. Fixes yet another MAC
1855 failed error on slow (dialup) connections. Affected file
1856 lib/silcclient/client.c and silcd/server.c.
1858 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1860 * Call check_version SKE callback for initiator too. Affected
1861 file lib/silcske/silcske.c.
1863 * Implemented fix for security hole found in the SKE that was
1864 fixed in the specification few days back; the initiator's
1865 public key is now added to the HASH value computation.
1866 Added backwards support for the old way of doing it too, for
1867 old clients and old servers. Affected file is
1868 lib/silcske/silcske.c.
1870 * Enabled mutual authentication by default in SKE. If initiator
1871 is not providing mutual authentication the responder will
1872 force it. This will provide the proof of posession of the
1873 private key for responder. The affected files are
1874 lib/silcclient/protocol.c and silcd/protocol.c.
1876 * Do not cache anymore the server's public key during SKE.
1877 We do mutual authentication so the proof of posession of
1878 private key is done, and if the server is authenticated in
1879 conn auth protocol with public key we must have the public
1880 key already. Affected file silcd/protocol.c.
1882 * Added new global debug variable: silc_debug_hexdump. If
1883 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1884 file lib/silcutil/silclog.[ch].
1886 * Fixed compilation warning due to char * -> const char *.
1887 Affected files lib/silcutil/silcnet.h, and
1888 lib/silccore/silcauth.[ch].
1890 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Fixed CMODE command when new channel key was created. If
1893 the creation failed the old key was removed. Next time giving
1894 same command would crash the server since the old key was
1895 freed already. Affected file silcd/command.c.
1897 * Fixed the silc_server_announce_get_channels to not crash
1898 on reconnect. Affected file silcd/server.c.
1900 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * Added silc_log_set_debug_string function to set a regex
1903 string to match for debug output. Only the function names,
1904 or filenames matching the given debug string is actually
1905 printed. This way it is possible to filter out those debug
1906 strings that user is not interested in.
1908 Fixed a bug in silc_string_regexify.
1910 Affected files lib/silcutil/silclog.[ch], and
1911 lib/silcutil/unix/silcunixutil.c.
1913 * Changed the -d options in both server and Irssi SILC client
1914 to take the debug string as argument. Affected files
1915 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1917 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Added silc_hash_babbleprint to create a Bubble Babble
1920 Encoded fingerprint. The encoding is developed by Antti
1921 Huima (draft-huima-babble-01.txt), and it creates human
1922 readable strings out of binary data. Affected file
1923 lib/silccrypt/silchash.[ch].
1925 * Print the babble print now in addition of fingerprint as well
1926 in Irssi SILC client. Affected files are
1927 irssi/src/fe-common/silc/module-formats.[ch],
1928 irssi/src/fe-common/silc/core/client_ops.c.
1930 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Fixed a security problem found in SKE. The initiator's
1933 public key too is now added to the HASH hash value creation
1934 which is signed by the responder to create the SIGN value.
1935 This will prevent anyone in the middle to lie to the responder
1936 about the initiator's public key. If this is done now, the
1937 man in the middle will get caught. Updated the protocol
1940 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Better installation directory handling. Configure module
1943 paths and other paths automatically to example_silc* files
1944 in doc/. A patch by toma.
1946 * Fixed compiler warning from MPI library, and from SILC RNG.
1949 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1950 It can be configured with ./configure. A patch by toma.
1952 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Find correct make to use in prepare-clean. A patch by
1955 toma. Affected file prepare-clean.
1957 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1959 * Added irssi variables use_auto_addr, auto_bind_ip,
1960 auto_bind_port and auto_public_ip.
1962 * Changed the interface for silc_client_send_key_agreement
1963 in lib/silcclient/silcapi.h
1967 irssi/src/silc/core/silc-core.c
1969 lib/silcclient/silcapi.h
1970 irssi/src/silc/core/silc-channels.c
1971 lib/silcclient/client_keyagr.c
1974 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * Added silc_pkcs_public_key_compare to compare two
1977 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1979 * Check that the client who set the founder mode on the
1980 channel is the same client that is giving the founder
1981 mode to itself. It is done by comparing the saved public
1982 key (it is saved even in the authentication is passphrase).
1983 Affected file silcd/command.c.
1985 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Do not process packet for disconnected socket connection.
1988 Affected file lib/silccore/silcpacket.c.
1990 * Process the DISCONNECT packet through scheduler in the
1991 client library. Affected file lib/silcclient/client.c.
1993 * Fixed the silc_client_packet_parse to not to increase
1994 the packet sequence number if the conn->sock and the
1995 current socket connection is not same. This can happen
1996 for example during key agreement when the conn includes
1997 multiple socket connections (listeners). Affected file
1998 lib/silcclient/client.c.
2000 * The sender of the file transfer request now provides also
2001 the pointer (listener) for the key exchange protocol. If
2002 the listener cannot be created then it sends empty key
2003 agreement and lets the receiver provide the listener.
2005 Added `local_ip' and `local_port' arguments to the
2006 silc_client_file_send. If they are provided they are used,
2007 if not then it will attempt to find local IP address, if
2008 not found or bind fails then the remote client will provide
2011 Affected files are lib/silcclient/client_ftp.c and
2012 lib/silcclient/silcapi.h.
2014 * Extended the FILE SEND command to support defining the
2015 local IP and port for key exchange listener. They are
2016 optional. Affected file irssi/src/silc/core/silc-servers.c.
2018 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Defined to WHOIS command reply the sending of fingerprint
2021 of the client's public key (if the proof of posession of the
2022 corresponding private key is verified by the server).
2023 Updated to the protocol specification.
2025 * Added support of receiving the client's public key's
2026 fingerprint in command reply in client library. Affected
2027 file is lib/silcclient/command_reply.c, and
2028 lib/silcclient/idlist.[ch].
2030 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * Do not send over 128 chars long nickname to the server
2033 in NICK command. Affected file lib/silcclient/command.c.
2035 * Do not send over 256 chars long channel names to the server
2036 in JOIN command. Affected file lib/silcclient/command.c.
2038 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Assure that silc_server_close_connection cannot be called
2041 twice for same socket context. Affected file is
2044 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Send error message to application if opening file for
2047 writing during file transfer fails. Affected file is
2048 lib/silcclient/client_ftp.c.
2050 Remove all file transfer sessions for a client that we're
2051 removing from ID cache.
2053 Affected file is lib/silcclient/client_ftp.c.
2055 * Fixed silc_net_addr2bin to return correct address. Affected
2056 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2058 * Fixed file transfer session removing on signoff notify.
2059 Affected file irssi/src/silc/core/silc-servers.c.
2061 * Added the SilcClientFileError to be returned in the monitor
2062 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2063 Affected file lib/silcclient/silcapi.h.
2065 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Fixed a crash in silc_client_ftp_free_sessions and
2068 silc_client_ftp_session_free_client. Affected file
2069 lib/silcclient/client_ftp.c.
2071 * Added `disabled' field in the SilcChannelEntry in the server
2072 to indicate if the server entry is disabled. Affected file
2073 silcd/idlist.h, silcd/command[_reply].c.
2075 * SILC server adds now /var/run/silcd.pid everytime it is
2076 started. Affected file silcd/silcd.c.
2078 * Added silc_server_packet_send_clients to send a packet to
2079 the provided table of client entries. Affected file
2080 silcd/packet_send.[ch].
2082 * Fixed a crash in client resolving in client_prvmsg.c in
2083 client library. Affected file lib/silcclient/client_prvmsg.c.
2085 * Do not actually remove the client directly from ID cache
2086 during SERVER_SIGNOFF, but invalidate it. This way we
2087 preserve the WHOWAS info for the client. Affected file
2088 silcd/server_util.c.
2090 * Fixed SERVER_SIGNOFF notify handling in the server. The
2091 server is now able to process incoming SERVER_SIGNOFF notify
2092 for a server that it doesn't even know about. It will remove
2093 the clients provided in the notify. Affected file
2094 silcd/packet_receive.c.
2096 * Check for partial packet in data queue after every packet that
2097 was found from the queue. Return and wait for more data if
2098 there is partial data in queue. Affected file is
2099 lib/silccore/silcpacket.c.
2101 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Added SilcClietFileError enum to indicate error in
2104 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2105 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2106 Affected files lib/silcclient/silcapi.h and
2107 lib/silcclient/client_ftp.c.
2109 * Check that newsize in silc_buffer_realloc is larger than
2110 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2112 * Added better monitor of file transfers. It now monitors
2113 key agreement protocol during the file transfer too. Added
2114 error reporting too. Affected files
2115 irssi/src/silc/core/silc-servers.c,
2116 irssi/src/fe-common/silc/module-formats.[ch].
2118 * Wrote a help file for FILE command.
2120 * Added silc_rng_global_get_byte_fast to get not-so-secure
2121 random data as fast as possible. Random data is read from
2122 /dev/urandom if available and from the SILC RNG if not
2123 available. It is used in padding generation. Affected file
2124 lib/silccrypt/silcrng.[ch].
2126 * All packets in client library are now processed synchronously.
2127 Optimized packet processing a lot. Affected file
2128 lib/silcclient/client.c.
2130 * All server connection packets are processing synchronously
2131 now in server, to optimize packet processing. Affected file
2134 * Include files are installed now only in Toolkit distribution
2135 if make install is given. Affected files: all Makefile.am's.
2137 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Assure that silc_client_notify_by_server_resolve does not
2140 resolve the client information multiple times. If it cannot
2141 be found by the first it cannot be found at all. Affected
2142 file lib/silcclient/client_notify.c.
2144 * Fixed WHOWAS command reply calling. Affected file
2145 lib/silcclient/command_reply.c.
2147 * Removed all references to silc_idlist_get_client from the
2148 Irssi SILC client since that call is internal call used by
2149 the library. The Irssi SILC client will use now client
2150 retrieval functions found in silcapi.h.
2152 * Fixed a bug in resolving nickname info before sending
2153 private message. It used freed memory. Affected file
2154 irssi/src/silc/core/silc-servers.c.
2156 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Assure my_channels statistics cannot go negative in server.
2159 Affected files silcd/server.c, silcd/server_util.c.
2161 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2175 * Added silc_net_localip to return local host's IP address.
2176 Affected file lib/silcutil/silcnet.[ch].
2178 * If key exchange or rekey protocol is active for a connection
2179 parse all packets syncronously since there might be packets
2180 in packet queue that we are not able to process without first
2181 processing packets before them. Affected file silcd/server,
2182 lib/silcclient/client.c.
2184 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2185 whether library should continue processing the packet.
2186 Affected file lib/silccore/silcpacket.h.

2217 lib/silcutil/silcutil.[ch].
2219 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Resolve the client info when received private message or
2222 channel message for a client which nickname we don't know.
2223 Affected files lib/silcclient/client_prvmsg.c and
2224 lib/silcclient/client_channel.c.
2226 * Do not crash in /KEY if client is not connected. Affected
2227 file irssi/src/silc/core/silc-channels.c.
2229 * Added SilcClientStatus field to the SilcClientEntry in the

2232 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2233 is incomplete and is being resolved, it won't be resolved
2236 Make sure also that USERS command reply does not resolve
2237 twice information. Affected file is
2238 lib/silcclient/command_reply.c.
2240 Make sure that silc_client_get_clients_by_list does not
2241 resolve twice same information.
2243 * Check for valid client->id in the silc_server_free_client_data.
2244 Affected file silcd/server.c.
2246 * Fixed /GETKEY nick@server not to crash if the server entry
2247 is not found. Affected file lib/silcclient/command.c.
2249 * Fixed the silc_server_check_cmode_rights to check the
2250 requested modes correctly. Affected file silcd/command.c.

2254 * Better checks for non-printable chars in nick added.
2255 Affected file silcd/command.c.
2257 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Call the silc_server_udpate_servers_by_server in the
2260 primary router that comes back online in the backup resuming
2261 protocol. Otherwise it routes packets wrong. Affected file
2262 silcd/server_util.[ch], silcd/server_backup.c.
2264 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2267 lib/silcutil/silcbuffmt.[ch].
2269 * Redefined the SILC packet header to include the padding
2270 length. Affected file lib/silccore/silcpacket.[ch].
2272 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2273 length for maximum padding up to 128 bytes). Affected
2274 file lib/silccore/silcpacket.h.
2276 * Removed all backwards support for old 0.5.x MAC thingies.
2277 The SILC packet header change makes it impossible to be
2278 backwards compatible.
2280 * Send the ENDING packet with timeout in the backup resuming
2281 protocol. This is to assure that all routers has connected
2282 to the primary router. Affected file silcd/server_backup.c.
2284 * Changed the RNG to take the first IV from random data. It
2285 used to take it from zero actually. Changed the RNG also
2286 to use /dev/urandom during session. /dev/random is used
2287 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2289 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Changed the SILC packet header to have the first two bytes
2292 (the packet length) encrypted. Affected files aroung the
2293 code tree, lib/silccore/silcpacket.[ch]. Removed the
2294 SilcPacketCheckDecrypt callback. It is not needed anymore
2295 since the silc_packet_receive_process will determine now
2296 whether the packet is normal or special.
2298 * Implemented the unidirectional MAC keys. Affected files
2299 lib/silcske/silcske.c, silcd/protocol.c and
2300 lib/silcclient/protocol.c.
2302 * Implemented the packet sequence number to the MAC computation.
2303 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2304 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2305 lib/silcclient/protocol.c.
2307 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Allow backup router to announce servers. All servers
2310 announced by backup router are added to the global list
2311 automatically. Update hte server's socket to our primary
2312 router also when backup router announces a server.
2313 Affected file silcd/packet_receive.c.
2315 * Do not update the client->router in the function
2316 silc_server_udpate_clients_by_server if the client is on
2317 global list. We might fail to find any specific server
2318 for locally connected clients and local cell clients. They
2319 should still use the `from' and not `to' as client->router.
2320 This fixes backup router resuming protocol. Affected file
2321 silcd/server_util.c.
2323 * Decrease channel statistics count only if the channel
2324 deletion worked. Affected files are silcd/server.c and
2325 silcd/server_util.c.
2327 * Added silc_server_update_servers_by_server to update origin
2328 of all server entries. Used during backup router protocol.
2329 Affected files silcd/server_util.[ch], silcd/server.c. and
2330 silcd/backup_router.c.
2332 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2333 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2334 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2335 lib/silccrypt/silchmac.c.
2337 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Assure that router cannot reroute the same channel message
2340 to the sender. Affected file silcd/packet_receive.c.
2342 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Made better checks that the channel message is not sent
2345 to the router it came from. Affected file is
2346 silcd/packet_send.c. Fixed memory leak too.
2348 * Announce informations for incoming router connection, but
2349 only after checking if it is replaced by backup router.
2350 Affected file silcd/packet_receive.c.
2352 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Fixed the backup resuming protocol to work in multiple
2355 router environment. Affected file silcd/server_backup.c.
2357 * Route packet only to one router in the function
2358 silc_server_packet_send_to_channel. Affected file is
2359 silcd/packet_send.c.
2361 * Fixed silc_server_send_notify_dest to set the broadcast
2362 flag. Fixed the silc_server_send_notify_topic to actually
2363 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2364 Affected file silcd/packet_send.c.
2366 * Changed the SFTP Filesystem interface. Changed the
2367 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2368 the filesystem operation function. The SilcSFTPFilesystem
2369 is now a context that is allocated by all filesystem allocation
2370 functions and it already includes the operations structure
2371 and filesystem specific context. It is given as argument
2372 now to the silc_sftp_server_start. This made the interface
2373 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2374 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2376 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Changed the backup router adding and getting interfaces
2379 in the server. The router that will be replaced by the
2380 specified backup router is now sent as argument. Affected
2381 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2384 * Added silc_net_addr2bin_ne to return the binary form of
2385 the IP address in network byte order. Affected files
2386 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2388 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Check for existing server ID in silc_server_new_server
2391 and in silc_server_connect_to_router_final and remove the
2392 old entry if it exists. Affected file silcd/packet_receive.c,
2395 * Send the channel message always to only one router, either
2396 in upstream or downstream. Affected file is
2397 silcd/packet_send.c.
2399 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Wrote the definition of the backup resuming protocol to the
2402 protocol specification.
2404 * Removed one redundant channel key generation from normal
2405 server during joining procedure. Removed one redundant
2406 channel key sending from server to router during joining
2407 procedure. Affected file silcd/command.c.
2409 * Made minor bugfixes to the backup router resuming protocol.
2410 Affected file silcd/server_backup.c, server.c.

2414 * Added --disable-asm configuration option. Affected files
2415 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2418 * Implemented the backup resuming protocol that is used to
2419 resume the primary router position in the cell after the
2420 primary router comes back online. Affected files
2421 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2422 and silcd/server_util.[ch].
2424 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Sleep two (2) seconds after sending QUIT command to server.
2427 Affected file lib/silcclient/command.c.
2429 * Assure that if outgoing data buffer is pending do not force
2430 send any data. Affected file silcd/packet_send.c.
2432 * Assure that if outgoing data buffer is pending do not force
2433 send any data. Affected file lib/silcclient/client.c.
2435 * Implemented the backup router support when the primary router
2436 goes down. The servers and routers can now use the backup
2437 router as new primary router without loosing connectivity.
2439 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2442 in the server to indicate disabled entry. All data read
2443 from the connection will be ignored and no data is sent
2444 for entry that is disabled. Affected files are
2445 silcd/idlist.h, silcd/server.c.
2447 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Created SFTP client and server test programs in the
2450 lib/silcsftp/tests directory.
2452 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Implemented memory filesystem (virtual filesystem) for
2455 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2458 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Implemented the SFTP (SSH File Transfer Protocol) to the
2461 lib/silcsftp. It includes SFTP client and SFTP server
2464 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Moved lib/silccore/silcprotocol.[ch] to the
2467 lib/silcutil library.
2469 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2470 take variable argument list pointer as argument. Affected
2471 file lib/silcutil/silcbuffmt.[ch].
2473 * Added silc_buffer_set function that is used to set data
2474 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2475 Affected file lib/silcutil/silcbuffer.h.
2477 * Changed various routines in the core library to use the new
2478 silc_buffer_set instead of allocating new buffer only for
2481 * Added 64-bit value formatting and unformatting support to the
2482 silc_buffer_[un]format routines. Affected file is
2483 lib/silcutil/silcbuffmt.[ch].
2485 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2486 to includes/bitmove.h.
2488 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Fixed channel user mode saving in client library. Affected
2491 file lib/silcclient/command[_reply].c.
2493 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Defined the file transfer to the SILC Protocol. Added
2496 new packet type SILC_PACKET_FTP and defined File Transfer
2497 Payload. The mandatory file transfer protocol is SFTP
2498 (SSH File Transfer Protocol). Affected file in addition
2499 of the internet draft is lib/silccore/silcpacket.h.
2501 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2502 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2503 is used as part of backup router protocol when the primary
2504 router of the cell is back online and wishes to resume
2505 the position as primary router.
2507 * Redefined the MAC generation keys in the protocol. The
2508 same key is not used anymore in both direction. Both
2509 direction will now use different keys for sending and
2510 receiving. This fixes a potential security flaw. This
2511 change causes incompatibilities in the protocol.
2513 * Redefined also the MAC computation from the packet.
2514 An packet sequence number is now added to the MAC
2515 computation. This prevents possible replay attacks against
2516 the protocol. This change too causes incompatibilities
2519 Added `sequence' field to the SilcPacketContext to hold
2520 the current sequence number for the packet.
2522 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2524 * Added `created' field to the SilcIDListData in the file
2525 silcd/idlist.h to indicate the time when the entry was
2528 * Added `created' field to the SilcChannelEntry too. Affected
2529 file silcd/idlist.h.
2531 * Added `creation_time' aguments to all the announcement functions
2532 in the server. If it is provided then only the entries that
2533 was created after the provided time frame are actually
2534 announced. Affected file silcd/server.[ch].
2536 * The protocol says that the Channel ID's IP address must be
2537 based on the router's IP address. Added check for this in
2538 the silc_server_new_channel when processing incoming New Channel
2539 Payload. Affected file silcd/packet_receive.c.
2541 * Print out the correct version with --version in SILC client.
2542 Affected file irssi/src/silc/core/silc-core.c.
2544 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Fixed WHOWAS command to check for completnes of the client
2547 entry always, not just when the command is coming from client.
2548 Affected file silcd/command.c.
2550 * Added new function silc_server_packet_queue_purge to purge the
2551 outgoing data queue to the network. After the function returns
2552 it is guaranteed that the outgoing packet queue is empty.
2553 Affected file silcd/packet_send.[ch].
2555 * Purge the outgoing packet queue in the rekey protocol's final
2556 callback to assure that all rekey packets go to the network
2557 before quitting the protocol. Affected file silcd/server.c.
2559 * Added silc_client_packet_queue_parse as similar function as
2560 in server to the client library. The affected file is
2561 lib/silcclient/client.c.
2563 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Splitted silcd/server.c and created silcd/server_util.[ch]
2566 for utility functions.
2568 * Added new socket flag SILC_SF_DISABLED to indicate that the
2569 connection is open but nothing can be sent to or received from
2570 the connection. Affected file lib/silcutil/silsockconn.[ch].
2571 The checking for disabled socket is checked in the low level
2572 silc_socket_write and silc_socket_read functions.
2574 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Allow only nicknames and channel names that fits into the
2577 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2579 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * When processing JOIN command reply in server check that if
2582 the channel exists in our global list we'll move it the local
2583 list. Affected file silcd/command_reply.c.
2585 * Fixed the check whether client is joined on the channel already
2586 in JOIN command. Affected file lib/silcclient/command.c.
2588 * Fixed the JOIN command reply to check whether the channel
2589 already exists. Affected file lib/silcclient/command_reply.c.
2591 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Added silc_ske_status_string to map the SKE error numbers
2594 to readable strings. The affected files are
2595 lib/silcske/silcske[_status].[ch].
2597 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Do not show the private channels on the WHOIS channel list
2600 as it is not allowed by the protocol. The affected file is
2603 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Assure that the packet length digged from the actual packet
2606 is something sensible in the silc_packet_decrypt_rest_special
2607 in lib/silccrypt/silcpacket.c.
2609 * Free and NULL the allocated pointer in silc_hmac_alloc if
2610 the HMAC allocation fails. The affected file is
2611 lib/silccrypt/silchmac.c.
2613 * Print the selected security properties to the log files in
2614 the server. Affected file silcd/protocol.c.
2616 * Add SKE's reference counter even if calling the completion
2617 callback manually. Otherwise it goes negative, although it
2618 does not cause any problems. The affected file is
2619 lib/silcske/silcske.c.
2621 * Remove the client entry with short timeout after giving the
2622 KILL command. Affected file lib/silcclient/command.c.
2624 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2625 case all found clients are already disconnected (WHOWAS would
2626 found them) in the server. Affected file silcd/command.c.
2628 * Update the last_receive (time of last data received) to be
2629 updated only when received private or channel message so that
2630 the idle time showed in WHOIS makes more sense.
2632 * Added boolean field `valid' in to the SilcClientEntry in the
2633 client library to indicate whether the entry is valid or not.
2634 This fixes the nickname change bug on channel when changing
2635 the nickname to be same than the old (like nick to Nick) the
2636 nickname formatter doesn't set the new nick anymore to Nick@host.
2637 Affected file lib/silcclient/idlist.[ch].
2639 * Now actually fixed the nickname changing on disconnection.
2640 Added new function silc_change_nick to the Irssi SILC Client.
2641 Affected file irssi/src/silc/core/client_ops.c,
2642 irssi/src/silc/core/silc-nicklist.[ch].
2644 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Check that the public key exists in the GETKEY command before
2647 trying to encode it. Affected file silcd/command.c.
2649 * Print some notifications on received public keys with GETKEY
2650 command in the Irssi SILC Client. Affected files are
2651 irssi/src/fe-common/silc/module-formats.[ch],
2652 irssi/src/silc/core/client_ops.c.
2654 * Use IDENTIFY command to resolve the server information in the
2655 GETKEY command instead of INFO command. Affected file
2656 lib/silcclient/command.c.
2658 * All command reply functions in the client library now calls
2659 the pending command reply callbacks even if an error has
2660 occurred. The server has done this a long time and now it was
2661 time to move the client library to this as well. Now all
2662 errors can be delivered back to the pending command reply
2663 callbacks if necessary. Affected files are
2664 lib/silcclient/command[_reply].[ch].
2666 * Change the nickname on disconnection back to the username
2667 because in reconnect the server will enforce it to it anyway.
2668 Affected file irssi/src/silc/core/silc-servers.c.
2670 * Fixed a config file parsing bug in the Irssi SILC client.
2671 Affected file irssi/src/silc/core/clientconfig.c.
2673 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * When printing the channel mode on JOIN, verify that the
2676 channel key and channel's HMAC are valid. Affected file
2677 irssi/src/silc/core/client_ops.c.
2679 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2682 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2683 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2685 * Removed channel key rekey task deleting from the function
2686 silc_server_save_channel_key. Affected file silcd/server.c.
2687 Added explicit timeout task context instead that is used to
2688 delete the task if we are registering a new task before the
2689 new task has elapsed.
2691 * When channel key rekey occurs the client library now saves
2692 the old channel key for a short period of time (10 seconds) and
2693 is able to use it in case some is still sending channel
2694 messages encrypted with the old key after the rekey. Affected
2695 file lib/silcclient/[idlist.h|client_channel.c].
2697 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2699 * Added check to the silc_server_new_id_real to not accept
2700 new ID if it is the sender's own ID. Affected file is
2701 silcd/packet_receive.c.
2703 * Assure that we do not announce ourself or the one we've
2704 sending our announcements when we're router and are announcing
2705 servers to our primary router. Affected file silcd/server.c.
2707 * Fixed silc_server_command_identify_check_client to assemble
2708 correct WHOIS packet. It send corrupted WHOIS packet and
2709 caused problem with router to router connections. Affected
2710 file silcd/command.c.
2712 Fixed also silc_server_command_whois_check the same way
2713 as for the IDENTIFY command.
2715 * Added new SilcIDListStatus to the server in the SilcIDListData
2716 structure. The status now includes the current status of
2717 the entry (like registered, resolved etc.). Affected file
2718 silcd/idlist.[ch]. Defined a bunch of different status types
2719 as well. This replaced the old boolean registered field as well.
2721 Added resolve_cmd_ident field to the SilcClientEntry structure
2722 too so that if the entry is for example being resolved so
2723 another command may attach to the same pending command reply
2724 without requiring to resolve the same entry again. This concept
2725 should optimize the WHOIS and the IDENTIFY resolving under
2726 heavy load by taking away unnecessary resolving for entries
2727 that are being resolved already.
2729 Added support for adding multiple pending commands for one
2730 command idenfier. Affected file silcd/command[_reply].[ch].
2732 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2733 before deleting the data. Otherwise the hash table will have
2734 freed data in comparison functions. Affected file is
2735 silcd/command_reply.c.
2737 * Fixed silc_idlist_replace_client_id to add the new entry to
2738 the cache with NULL nickname. Otherwise there will be invalid
2739 memory as the nickname after the nickname is freed. Affected
2740 file silcd/packet_receive.c.
2742 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2743 saved into wrong slots because the previous number of entries
2744 was not taken into account. Affected file silcd/idlist.c.
2745 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2747 * If we are router and we receive JOIN notify to a channel that
2748 does not have any users then notified client is marked as the
2749 channel founder, as it is it. The affected file is
2750 silcd/packet_receive.c
2752 * Added to the extended hash table API's table_del_*ext functions
2753 the destructor as argument too, so that the caller can decide
2754 which destructor to use or whether to use destructor at all.
2755 Affected file lib/silcutil/silchashtable.[ch].
2757 * Fixed ID Cache purging. It actually deleted the entries from
2758 the hash table after the data was freed. The hash table ended
2759 up comparing freed memory. The affected file is
2760 lib/silccore/silcidcache.c.
2762 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Fixed Irssi SILC client's KILL command's HELP syntax.
2766 * The USERS command now resolves the detailed user information
2767 if the userinfo field is missing. Affected file is
2768 lib/silcclient/command_reply.c.
2770 * Do not print error in silc_file_read if the read file does
2771 not exist. Just silently return NULL. Affected file is
2772 lib/silcutil/silcutil.c.
2774 * Fixed the silc_log_output to not wine about NULL filename
2775 and to not create some bogus " " filename. Affected file is
2776 lib/silcutil/silclog.c.
2778 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Fixed various printing bugs on the user interface in the
2781 Irssi SILC Client. Minor changes that were forgotten from
2784 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Fixed the configure.in.pre and the compilation and distribution
2787 environment to support the new autoconf 2.52. That version is
2788 now required to compile the CVS trunk.
2790 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2793 to generally parse user@fqdn format strings. Affected file
2794 lib/silcutil/silcutil.c.
2796 * Added nickname_format and nickname_force_format fields to the
2797 SilcClientParams structure. The first one defines the format
2798 for the nicknames that the library will enforce if the receives
2799 multiple same nicknames. The second one is boolean value and
2800 can be used to force the library to always enforce the format
2801 to the nicknames regardles whether there are multiple nicknames
2802 or not. This configurable formatting was employed to flexibly
2803 support accessing multiple nicknames from the user interface.
2804 The userinterface can now set the nicknames to what ever format
2805 they prefer. Affected file lib/silcclient/silcapi.h.
2807 Added function silc_client_nickname_format to the file
2808 lib/silcclient/idlist.c. It performs the nickname formatting.
2810 Added new field `hostname´ to the SilcClientEntry context.
2811 It holds the hostname of the client. Affected file is
2812 lib/silcclient/idlist.h.
2814 * Irssi SILC Client sets the nicknames in nick@hostn format.
2815 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2816 irssi/src/silc/core/silc-core.c.
2818 The WHOIS printing now also shows both the real nickname and
2819 the formatted nickname so that user knows how to access the
2820 user if there are multiple same nicknames cached. Affected
2821 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2822 printing formatting too to take the hostname now as a separate
2823 argument. The Affected file is
2824 irssi/src/fe-common/silc/modules-formats.[ch].
2826 * Changed the silc_client_get_clients_local to accept the formatted
2827 nickname as argument. It accepts the real nickname too but the
2828 formatted nickname can be used to find the true entry from
2829 multiple entries. Affected file lib/silcclient/silcapi.h and
2830 lib/silcclient/idlist.c.
2832 * Added nickname_format_parse field to the SilcClientParams.
2833 It is a callback function provided by the application to parse
2834 the nickname out of the formatted nickname string. The library
2835 calls it to get the nickname from the formatted string. Since
2836 the application generally knows better the format of the nickname
2837 string it parses it instead of the library, even though library
2838 encodes the formatted string. If the callback function is not
2839 provided then the library will use the string as is. The
2840 affected file is lib/silcclient/silcapi.h.
2842 * All the nickname strings passed to the client library in
2843 commands are now expected to be formatted nickname strings.
2844 If the command does not support the formatted nickname string
2845 it will assume that the sent string is the actual nickname.
2846 Affected file lib/silcclient/command.c.
2848 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Added public key authentication support to OPER and SILCOPER
2851 commands in the client library. Affected file is
2852 lib/silcclient/command.c.
2854 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Changed the get_auth_methdod client operation to be asynchronous.
2857 It can be async if the application resolves the authentication
2858 method from the server during the negotiation. Added new
2859 SilcGetAuthMeth completion callback that the application will
2860 call after resolving the authentication method.
2862 Added function silc_client_request_authentication_method that
2863 the application can use to resolve the authentication method
2864 from the server. Added also SilcConnectionAuthRequest callback
2865 that the library will call after the server has replied. The
2866 application can call this function if it does not know the
2867 current authentication method.
2869 Affected files are lib/silcclient/client.c and
2870 lib/silcclient/silcapi.h.
2872 * The Irssi SILC client now automatically resolves the authentication
2873 method incase any configuration information is not present (and
2874 currently there never is). The affected file is
2875 irssi/src/silc/core/client_ops.c.
2877 * Fixed public key authentication from the client library.
2878 Affected file lib/silcclient/protocol.c. Changed also the
2879 protocol specification about the public key authentication in
2880 the connection authentication protocol. The actual data to be
2881 signed is now computed with a hash function before signing.
2883 * Fixed the public key authentication from the server as well.
2884 Affected file silcd/protocol.c.
2886 * Removed the mlock()'s from the memory allocation routines.
2887 Affected file lib/silcutil/silcmemory.c. The ./configure does
2888 not check anymore for the mlock(). Affected file is
2891 * Fixed USERS command in server to allow the execution of the
2892 command for private and secret channels if the client sending
2893 the command is on the channel. Affected file silcd/command.c.
2895 * Fixed silc_client_get_clients_local to return the clients
2896 count correctly. It could return wrong value. Affected file
2897 lib/silcclient/idlist.c.
2899 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2902 types. The assembler optimizations seemed not to like 64-bit
2903 data types. The assmebler optimizations thus are now enabled
2904 also for BSD systems as opposed to only enable them for Linux.
2906 * Do not check for threads at all on BSD systems. Affected
2907 file configure.in.pre.
2909 * Removed -n and -h options from the Irssi SILC Client since
2910 they are not used in silc.
2912 * Fixed the prime generation to assure that the first digit
2913 of the generated random number is not zero since our conversion
2914 routines does not like number strings that starts with zero
2915 digit. If zero digit is seen the random number is regenerated.
2916 This caused some corrupted RSA keys when the zero first digit
2917 was met. Affected file lib/silcmath/silcprimegen.c.
2919 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Fixed WIN32 configuration in the ./configure script.
2922 Fixed to include xti.h on environments that has it.
2923 Patches by Carsten Ilchmann and andrew.
2925 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Changed the silc_id_create_client_id to be collision
2928 resistant. It is now assured that there cannot be created
2929 two same client ID's. I suspect that some weird bugs in
2930 the server were actually caused by duplicate Client IDs.
2931 Affected file silcd/serverid.[ch]. A router receiving
2932 new ID now also assures and informs the sending server
2933 if the ID caused collision.
2935 * Changed the silc_id_create_channel_id to also assure that
2936 there are no collisions.
2938 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * Statement about ignoring the Mutual Authentication flag when
2941 performing rekey with PFS was a bit misleading. It is ignored
2942 if it was set in the initial negotiation, it cannot be even
2943 set in the rekey. Fixed in the ke-auth draft. Started the
2944 new versions of the protocol drafts in the doc/.
2946 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Fixed a bug in silc_client_command_identify_save when saving
2949 new channel information. The channel name was no duplicated
2950 and caused crash on exit. Affected file is
2951 lib/silcclient/command_reply.c.
2953 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Fixed the getkey command handling in the server. Send just
2956 empty OK reply to the sender if the key could not be fetched
2957 (but everything else was ok, like the key just was not available).
2958 Changed the public key parameter to optional in the protocol
2959 specs so that empty OK reply can be sent. Affected file
2962 Added a message to Irssi SILC client to tell to user if the
2963 server did not return a public key.
2965 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Fixed a channel key regeneration bug. It registered new
2968 timeout tasks exponentially until all system resources were
2969 used. Affected file silcd/server.c.
2971 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Added the SILC Document generator to the scripts/silcdoc.
2974 It can be used to generate the Toolkit Reference Manual out
2975 of the source tree. Internally it will also use the RoboDoc
2976 generator now imported in util/robodoc.
2978 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Added couple of return's in rekey protocol if error orccurred
2981 during the protocol. The execution must be terminated.
2982 Affected file silcd/protocol.c. Also, terminate the protocol
2983 always with timeout.
2985 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * The client's Client ID was created initally from the wrong
2988 nickname (it could have been in format nick@host) in the
2989 silc_server_new_client. Affected file silcd/packet_receive.c
2991 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Added some SILC_LOG_ERROR's to various error conditions
2994 if client could not be added to ID cache. Affected files
2995 silcd/packet_receive.c and silcd/server.c.
2997 * When client's sock->user_data is freed, NULL also the
2998 client->router and client->connection pointers. Added check
2999 for these pointers being NULL to various places around the
3000 code. Affected file silcd/server.c.
3002 * Added client->data.registered == TRUE checks to various
3003 places around the code to assure that unregistered client's
3004 are not handled when it is not allowed. Affected file
3007 * Added `bool registered' fields to all
3008 silc_idlist_[server|client]_get_* routines to indicate whether
3009 the fetched client needs to be registered or not. Affected
3010 file silcd/idlist.[ch].
3012 * Add your own entry as registered to the ID cache in the
3013 server. Affected file server.c.
3015 * Fixed a bug in silc_server_new_server. The SilcServer was
3016 set as the new server's context instead of SilcServerEntry.
3017 This naturally caused some weird bugs.
3019 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Do not delete the channel rekey task when adding it
3022 for in silc_server_create_channel_key.
3024 * Changed the silc_server_create_channel_key to return
3025 TRUE or FALSE to indicate the success of the channel key
3028 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Fixed MSVC++ project files and added missing files to
3031 Makefiles under win32/.
3033 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Do not add TCP_NODELAY flag if the operating system
3036 does not have it defined. Affected files are
3037 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3039 * Fixed buffer overflow from Irssi SILC Client. Affected
3040 file irssi/src/fe-common/core/themes.c.
3042 * Fixed double free in client library in the file
3043 lib/silcclient/client.c when disconnecting from server.
3045 * Applied double free patch from cras to Irssi SILC client.
3046 Affected files irssi/src/core/[modules/expandos].c
3048 * Fixed the disconnection handling to Irssi SILC Client.
3049 The application must call silc_client_close_connection
3050 in ops->connect client operation in case of failure of
3051 the connection. Affected file is
3052 irssi/src/silc/core/client_ops.c.
3054 * Do not set sock->protocol to NULL in the function
3055 silc_client_close_connection after executing the protocol's
3056 final callback since the sock might not be valid anymore.
3057 Affected file lib/silcclient/client.c.
3059 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Do not enable SILC_THREADS if the linking with libpthread
3062 did not happen. Affected file configure.in.pre.
3064 * Added notion to protocol specification that server must
3065 verify the sent authentication payload with CMODE when
3066 setting the channel founder key. Implemented it to the
3067 server. Affected file silcd/command.c.
3069 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3071 * Added _EXTRA_DIST SILC distribution variable to the
3072 distributions file. It is used to conditionally add extra
3073 files or directories to the specific distribution. Affected
3074 files ./prepare, Makefile.am.pre and distributions.
3076 Removed the `_' from the start of the distribution names.
3079 * Added README.WIN32 for instructions to compile the Toolkit
3082 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Fixed a double free in disconnection in the server. Affected
3085 file is silcd/server.c.
3087 * Fixed the lib/silcske/groups.c to work now also with GMP
3088 MP library. The string conversion did not work when using
3089 specific base and the base is indicated in the string as well.
3091 * Created win32/ directory which now includes MSVC++ specific
3092 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3093 It will appear only in the toolkit distribution
3095 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Changed the key material distribution function in case when
3098 the hash output is too short. The data is now concatenated
3099 a bit differently than it used to. Made the change to the
3100 SKE protocol specification.
3102 * Added better GMP detection to configure.in.pre. A patch
3105 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Fixed a minor bug in SKE that might cause some problem on
3108 some platforms. Affected file lib/silcske/silcske.c.
3110 * Added the cookie checking for initiator in the SKE. It checks
3111 that the responder returns the sent cookie unmodified. The
3112 affected file is lib/silcske/silcske.c. Added new SKE
3113 error type INVALID_COOKIE that can be sent during the
3114 negotiation. Fixed some memory leaks as well.
3116 * Added the "invalid cookie" error message to Irssi SILC client's
3119 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Added `task_max' field to the SilcClientParams to indicate
3122 the maximum tasks the scheduler can handle. If set to zero,
3123 default values are used. Affected file lib/silcclient/silcapi.h.
3125 * Fixed memory leaks in silc_client_close_connection. Affected
3126 file lib/silcclient/client.c.
3128 * Added silc_client_del_client_entry to client library to free
3129 all memory of given client entry. Affected file is
3130 lib/silcclient/idlist.[ch].
3132 * Added new functions silc_client_del_channel and
3133 silc_client_del_server to delete channel and server entries.
3134 Affected file lib/silcclient/[silcapi.h/idlist.c].
3136 * Removed silc_client_del_client_by_id from silcapi.h.
3138 * Fixed the INFO command to return the server's own info
3139 correctly when querying by Server ID. Affected file is
3142 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Removed the non-blocking settings in WIN32 code in the
3145 silc_sock_[read/write] and added SleepEx instead. Affected
3146 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3147 of input data is now checked with FIONREAD and ioctlsocket.
3149 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Call silc_schedule_task_del_by_context in the
3152 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3153 Affected file lib/silccore/silcprotocol.c.
3155 * Call silc_protocol_cancel for active protocols in the
3156 silc_server_close_connection if the funtion
3157 silc_server_free_sock_user_data has not been called.
3158 Affected file silcd/server.c.
3160 * Generic tasks cannot be deleted using the del_by_fd
3161 task deleting function since generic tasks does not match
3162 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3164 * Added a notion to SILCOPER help file that the SILCOPER works
3165 only on router server, not on normal server.
3167 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3169 * Added for WIN32 support for the new scheduler as well.
3170 Affected file lib/silcutil/win32/silcwin32schedule.c.
3172 * Fixed the SHA1 implementation to work on various platforms.
3174 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3177 API. It is part of the scheduler now. Everything else is
3178 as previously but some functions has changed their names.
3179 Checkout the lib/silcutil/silcschedule.h for the interface.
3180 Updated all applications to use the new interface. Affected
3181 files are lib/silcutil/silcschedule.[ch].
3183 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Found a bug in the SKE implementation. The HASH value,
3186 specified by the protocol, was not computed correctly. The
3187 public key of the responder was not added to the computation
3188 even though it is mandatory. Affected file lib/silcske/silcske.c.
3189 This unfortunately causes incompatibilities with older
3190 clients and servers.
3192 * Added WIN32 specific network init and uninit functions:
3193 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3194 the Winsock2. Affected file lib/silcutil/silcnet.h and
3195 lib/silcutil/win32/silcwin32net.c.
3197 * Set the socket always to nonblocking mode on WIN32 after
3198 reading data or writing data. Affected file is
3199 lib/silcutil/win32/silcwin32sockconn.c.
3201 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Fixed various compilation problems under WIN32. Affected
3204 files lib/silcutil/win32/silcwin32thread.c and
3205 lib/silcutil/win32/silcwin32schedule.c.
3207 * Removed all _internal.h #includes from public header
3208 files. Internal headers must never be included from
3211 Removed also the lib/silcske/payload_internal.h file.
3213 * All include files that may be needed (public and some others
3214 included by the public headers) by application developers are
3215 now copied to the ./includes directory. It does not copy any
3216 internal headers. Affected file Makefile.defines.pre and all
3217 Makefile.am's under lib/ and subdirs.
3219 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3221 * Do not change the ~/.silc directory's permissions automatically.
3222 Affected file irssi/src/silc/core/clientutil.c.
3224 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * Do not cancel the protocol in silc_server_close_connection
3227 it might cause recursion. Now cancelled in the function
3228 silc_server_free_sock_user_data. Affected file silcd/server.c.
3230 * Fixed the silc_server_remove_clients_by_server to regenerate
3231 the channel keys correctly finally. Added also new function
3232 silc_server_remove_clients_channels to actually do it.
3233 Affected file silcd/server.c.
3235 * Fixed the silc_server_new_channel to not crash by giving
3236 wrong router to the new channel. Affected file is
3237 silcd/packet_receive.c.
3239 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3242 which is given as argument to the silc_client_alloc now.
3243 It can be used to configure the client and set various parameters
3244 that affect the function of the client.
3246 * The USERS command in server did not check whether the channel
3247 is private or secret. Affected file silcd/command.c.
3249 * Added new argument to the USERS command in protocol specification.
3250 The USERS command now can take the channel name as argument
3251 as well. Added support for this in client and server and
3252 updated the protocol specs.
3254 * Completed the GETKEY command in client. It can be now used
3255 to fetch also servers public key not only some clients.
3256 Affected files lib/silcclient/command[_reply].c.
3258 * Added silc_client_get_server to return server entry by the
3259 server name. Affected files lib/silcclient/silcapi.h and
3262 * Redefined the IDENTIFY command in protocol specification to be
3263 more generic. It now can be used to query information about
3264 any entity in the SILC Network, including clients, servers and
3265 channels. The query may be based either the entity's name
3266 or the ID. Added support for this in both client and server.
3268 Affected files silcd/command.c and lib/silcclient/command.c
3269 and command_reply.c.
3271 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3272 the _from_client and _from_server functions. Affected file
3275 * Added silc_client_get_channel_by_id_resolve to the file
3276 lib/silcclient/silcapi.h to resolve channel information by
3277 its ID. Added also silc_client_get_channel_by_id that
3278 does not resolve it from the server.
3280 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Added SilcServerEntry context into the client library
3283 to represent one server. The INFO command now allocates
3284 these to save the resolved server info. For now on the
3285 client library will also keep information about servers,
3286 connected and resolved with INFO.
3288 The INFO command now allocates the SilcServerEntry context
3289 and saves the server info there. The COMMAND_REPLY in
3290 the INFO now returns the parameters to application in
3291 same order as defined in the protocol specification.
3293 The entries are cached in the client->server_cache.
3295 * The INFO command is now issued after received the Client ID
3296 from the server. Affected file lib/silcclient/client.c.
3298 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3299 to the application as the mode changer might be server.
3300 It is guaranteed that NULL is not returned anymore to the
3301 application. Affected file lib/silcclient/client_notify.c.
3303 The ID Type is now also passed to the application so that
3304 it can check whether the returned entry is SilcClientEntry
3307 Added new function silc_client_get_server_by_id to return
3308 the server entry by ID. Affected files are the
3309 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3311 * Do not create the channel in the Irssi SILC Client when issuing
3312 the JOIN command but when received the sucessful JOIN command
3313 reply. Otherwise the channel might get created even though we
3314 could not join it. The Affected file is
3315 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3317 * Fixed a channel joining bug in router. The router must also
3318 check the channel modes, invite and ban lists etc. when serving
3319 the JOIN command sent by normal server. Affected file is
3320 silcd/command.c. The router now resolves the client's
3321 information from the server who sent the JOIN command if it
3322 does not know it, and processes the JOIN command only after
3325 * Changed the SilcCommandCb to take new argument; void *context2.
3326 Affected file lib/silccore/silccommand.h
3328 The second argument in the command callbacks in the server now
3329 includes the SilcServerCommandReplyContext if the command was
3330 called as pending command callback from the command reply.
3331 Otherwise it is NULL. When called as pending the status of the
3332 command reply will be checked and if it was erronous the
3333 error will be sent to the original sender of the command.
3334 This way the client always receives the error messages even
3335 though the server was actually the one who received the error
3336 when it resent the command to router, for example. Affected
3337 files silcd/command[_reply].[ch].
3339 * Fixed sending WHOWAS command's error message to client if
3340 the requested client could not be found. It was missing.
3343 * Changed the CMODE and CUMODE commands reply arguments in the
3344 protocol specification. The Channel ID is now sent in both
3345 of the commands to identify the channel. Implemented this
3346 new feature to the client and server. Affected files
3347 lib/silcclient/command_reply.c and silcd/command.c.
3349 * Made better checks for invite and ban lists in the JOIN
3350 command in server. Affected file silcd/command.c.
3352 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * The server now performs the incoming host IP/DNS lookup
3355 using the silc_socket_host_lookup and thus does not block
3356 the server anymore. Affected file silcd/server.c.
3358 * Completed the multi-thread support for SILC Scheduler in
3359 the lib/silcutil/silcschedule.c.
3361 * Fixed the configure.in.pre to detect the pthread correctly
3364 * Fixed a deadlock in silc_task_queue_wakeup in the file
3365 lib/silcutil/silctask.c.
3367 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Added new function silc_schedule_wakeup that is used in
3370 multi-threaded environment to wakeup the main thread's
3371 schduler. It needs to be used when a thread adds a new task
3372 or removes a task from task queues. After waking up, the
3373 scheduler will detect the task queue changes. If threads
3374 support is not compiled in this function has no effect.
3375 Implemented the wakeup mechanism to both Unix and WIN32
3376 systems. Affected files are lib/silcutil/silcschedule.[ch],
3377 lib/silcutil/unix/silcunixschedule.c and the
3378 lib/silcutil/win32/silcwin32schedule.c.
3380 * Added new function silc_task_queue_wakeup to wakeup the
3381 scheduler by the specified task queue. Affected file
3382 lib/silcutil/silctask.[ch].
3384 * The silc_socket_host_lookup_start now wakes up the scheduler
3385 after adding the timeout task. Affected file is
3386 lib/silcutil/silcsockconn.c.
3388 * The silc_socket_host_lookup is synchronous now if the threads
3389 support is not compiled in. However, the callback is still
3390 called asyncronously through the scheduler, anyway. Affected
3391 file lib/silcutil/silcsockconn.c.
3393 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Added new function silc_socket_host_lookup to perform
3396 asynchronous IP and FQDN lookups for the socket connection.
3397 Affected files lib/silcutil/silcsockconn.[ch].
3399 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3402 that may or may not compile the mutex support in.
3404 Changed the silc_mutex_alloc interface. It allocates the
3405 mutex now to the sent pointer and returns TRUE or FALSE.
3407 Affected file lib/silcutil/silcmutex.h.
3409 * Wrote the SILC Task Queue interface to support multi-threads.
3410 Affected file lib/silcutil/silctask.[ch].
3412 * Wrote the SILC Scheduler to support multi-threads. Affected
3413 file lib/silcutil/silcschedule.c.
3415 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3417 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3418 in lib/silcutil/win32/.
3420 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Defined SILC Mutex API and SILC Thread API and implemented
3423 them for Unix. Affected files are
3424 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3425 lib/silcutil/unix/silcunixmutex.c and
3426 lib/silcutil/unix/silcunixthread.c.
3428 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Fixed the silc_server_remove_clients_by_server's channel
3431 key re-generation. The hash table handling was incorrect
3432 and would not work with many channels. Affected file is
3435 * Fixed some memory leaks around the server code.
3437 * Rewrote the silc_server_get_users_on_channel to support IPv6
3438 based Client ID's. Affected file silcd/server.c.
3440 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3441 specification. However, a separate document must be written
3442 to define the detailed signing procedure and the payload
3443 associated with the flag. Defined the flag to the
3444 lib/silccore/silcchannel.h as well.
3446 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Changed the dynamic tables to static size tables in the
3449 lib/silccrypt/silchmac.c.
3451 * Removed GCC dependencies from the code. A patch by cras.
3453 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Do not show the error "Error receiving packet bla bla"
3456 in server if it really was not an error (-2 means that reading
3457 is pending). Affected file silcd/server.c.
3459 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Fixed a possible crash in silc_server_remove_clients_by_server
3462 in silcd/server.c. Fixed there also some memory leaks.
3464 * Fixed the silc_idlist_replace_client_id. It could replace
3465 wrong key in the hash table. Affected file silcd/idlist.c.
3467 * Do not check whether there are global users on the channel
3468 if the channel->global_users is FALSE. Affected functions
3469 silc_server_remove_from_one_channel and
3470 silc_server_remove_from_channels in silcd/server.c. Also,
3471 do not check if the removed client is local as we can be
3472 sure that global client was not removed from the channel
3473 and checking for global users is not needed.
3475 * The silc_server_remove_clients_by_server now re-generates
3476 the channel keys correctly for those channels that had
3477 clients removed from them. Affected file silcd/server.c.
3479 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Found the reason of random crashes in the server. We weren't
3482 ignoring the SIGPIPE signal (which can be sent in write())
3483 and it crashed the server. Affected file silcd/silcd.c.
3485 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Assure that sock->user_data is not NULL in the function
3488 silc_server_packet_send in silcd/packet_send.c.
3490 * Disconnect the remote connection if it could not be added
3491 to any ID lists in the server. The affected file is
3494 * Check in silc_server_packet_send[_real/dest] that the
3495 socket is not disconnecting and ignore the data if it is.
3496 Affected file silcd/packet_send.c.
3498 * Define inline to __inline on native WIN32 compilation.
3499 Affected file includes/silcwin32.h.
3501 * Added some explicit type casts for inline code since MSVC
3502 require them. Affected files lib/silcutil/silcbuffer.h,
3503 lib/trq/silcdlist.h and lib/trq/silclist.h.
3505 * Print warning in log files from now on if the packet
3506 decryption fails. Affected file silcd/server.c.
3508 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Changed the `say' client operation's interface to accept
3511 new `type' argument to indicate the type of the message sent
3512 by the library. The application may filter the library's
3513 messages according the type. The affected file is the
3514 lib/silcclient/silcapi.h.
3516 * Added two new functions to lib/silcclient/silcapi.h:
3517 silc_client_del_client and silc_client_del_client_by_id.
3518 Affected file lib/silcclient/idlist.c.
3520 * Moved the clientincludes.h from includes/ to silc/ and
3521 serverincludes.h from includes/ to silcd/.
3523 * The modes for the CMODE and CUMODE are now passed as
3524 uint32 for application with COMMAND_REPLY. The affected
3525 file is lib/silcclient/command_reply.c.
3527 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * /WHOIS without arguments shows client's own information.
3530 Affected file lib/silcclient/command.c.
3532 * Changed PING to not accept any arguments. The specs
3533 says that client can ping only the connected server so
3534 requiring an argument is not needed. Affected file is
3535 lib/silcclient/command.c.
3537 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3539 * Fixed a fatal bug in private message sending and reception
3540 encryption and decryption when using private message keys.
3541 The implementation was incorrect and did not follow the
3542 specification. It causd that some of the message were
3543 lost since it did not use the sending and receiving keys
3544 as the protocol suggests. This has been fixed and will cause
3545 incompatibilities with older clients when sending private
3546 message encrypted with private message keys. Affected files
3547 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3548 and various other in Irssi SILC Client.
3550 Added `responder' boolean argument to the functions
3551 silc_client_add_private_message_key[_ske] to indicate when
3552 the key is added as responder or initiator of the key
3555 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Removed the silc_ske_check_version function and created
3558 a SilcSKECheckVersion callback. Added also a function
3559 silc_ske_set_callbacks that is now used to set all SKE
3560 callbacks. The callback functions are not given to
3561 the SKE functions anymore, but this function is used to
3564 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3566 * Added `silc_version' argument to the silc_client_alloc
3567 to define the version of the application for the library.
3568 The library will use the version string to compare it
3569 against the remote host's (usually a server) version
3570 string. Affected file lib/silcclient/silcapi.h
3572 * Added the KE protocol context to Key Agreement context
3573 in client library so that we can abort the SKE if it
3574 is in process when we get timeout. Affected file is
3575 lib/silcclient/client_keyagr.c.
3577 * Do not resolve the client ID forever if it returns in the
3578 first time that such client does not exist. This was done
3579 for example with private message. Affected file is
3580 lib/silcclient/client_prvmsg.c.
3582 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3584 * Do not add regex.h for WIN32. The affected file
3585 includes/silcincludes.h.
3587 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3588 not work yet 100%. It generates the DLL's automatically
3589 when compiling with --with-win32 under cygwin.
3591 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * lib/contrib/regex.c is not compiled on WIN32.
3595 * Added silc_net_get_socket_opt function to the
3596 lib/silcutil/silcnet.h.
3598 * Added includes/silcwin32.h for WIN32 specific includes
3601 * Do not use ptime structure or any of the posix process
3602 functions on WIN32 in lib/silccrypt/silrng.c.
3604 * Added silc_gettimeofday to provide generic function
3605 for struct timeval on all platforms. Added the function
3606 to lib/silcutil/silcutil.h.
3608 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3611 library as they clearly belong there. As a plus side we
3612 can make the actual socket connection routines platform
3615 Added also new generic function silc_socket_read and
3616 silc_socket_write (that used to be silc_packet_[read/write].
3617 The implementation of these are platform specific.
3619 * Added WIN32 specific routines of silc_socket_[read/write]
3620 to lib/silcutil/win32/silcwin32sockconn.c.
3622 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3624 * Added preliminary support for native WIN32 compilation under
3625 cygwin (using the -mno-cygwin option for GCC) to the
3626 ./configure.in.pre. The --with-win32 now prepares the
3627 compilation for native WIN32.
3629 * Rewrote the SILC Scheduler interface in the file
3630 lib/silcutil/silcschedule.h. The scheduler is now context
3631 based and does not have anymore any global static scheduler.
3632 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3633 and created lib/silcutil/win32 directory for WIN32 based
3636 * Added Unix specific network routines to the
3637 lib/silcutil/unix/silcunixnet.c and the old
3638 lib/silcutil/silcnet.c includes now only generic routines.
3640 Added WIN32 specific network routines to the
3641 lib/silcutil/win32/silcwin32net.c.
3643 * Added Unix specific utility functions from the
3644 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3646 * Added WIN32 SILC Scheduler to the file
3647 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3650 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3652 * Do not handle JOIN notify in the server if the target client
3653 is not registered (idata->registered == FALSE). The affected
3654 file is silcd/packet_receive.c.
3656 * Update the nickrec->founder in event_cumode in the Irssi SILC
3657 client. Affected file irssi/src/silc/core/silc-channels.c.
3659 * Fixed the CUMODE_CHANGE notify handling in the server when
3660 server and router are announcing their clients on channels.
3661 Now the mode changes are saved and notified correctly. The
3662 affected file is /silcd/packet_receive.c.
3664 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3665 They really did not replace the cache entry in the ID Cache.
3666 Now they do that. Affected file silcd/idlist.c.
3668 * Fixed the KICK notify handling in the Irssi SILC client to
3669 update the channel records so that the kicked client does not
3670 appear to be on the channel. The affected file is
3671 irssi/src/silc/core/silc-channels.c.
3673 * Always update the conn->current_channel when executing command
3674 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3676 * Fixed the KILL notify handling in Irssi SILC client to remove
3677 the killed client on all channels.
3679 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Fixed the silc_parse_command_line to remove extra spaces
3682 from the start and end of the arguments. Affected file is
3683 lib/silcutil/silcutil.c.
3685 * Cancel and free any active protocol in the function
3686 silc_server_close_connection. Affected file silcd/server.c.
3688 * Cancel and free any active protocol in the function
3689 silc_client_close_connction. Affected file is
3690 lib/silcclient/client.c.
3692 * Do not execute the KILL command for clients that are in
3693 history (ie. they are not in the network). Affected file is
3696 * Fixed KILL notify handling, client does not crash anymore.
3697 Affected file irssi/src/silc/core/silc-channels.c.
3699 * Reduced the default packet buffer size from 2048 to 1024 in
3700 lib/silccore/silcpacket.c.
3702 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3703 counter to the SKE context that is incresed when the SKE library
3704 performs async operation outside the library. If the outside
3705 process frees the SKE context and FREED status will be set
3706 and the library will detect after the sync operation that the
3707 libary is freed. The affected files are
3708 lib/silcske/silcske[_status].[ch].
3710 * Resolve the client entry information in the function
3711 silc_client_channel_message to assure that NULL pointer is not
3712 passed as client entry to the application. */
3714 * Fixed the task timeout calculation to assure that there is
3715 never negative timeouts. The affected file is
3716 lib/silcutil/silcschedule.c.
3718 * Fixed the channel user mode notification sending in server.
3719 It was sent point-to-point to the router (or to server by router)
3720 but it needs to be destined to a channel. The routines now
3721 supports sending the channel user mode notifys to the channels
3722 when announcing clients and channels. Affected files are
3723 silcd/server.c and silcd/packet_receive.c.
3725 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3726 It did not actually replace the old channel entry in the cache.
3727 Affected file lib/silcclient/client_notify.c.
3729 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Fixed a possible crash in silc_packet_send_prepare. It now
3732 assures always that there is enough space in the buffer and
3733 at the tail area of the buffer (for MAC).
3735 Fixed the inbound buffer reallocation in silc_packet_read.
3736 It was old code and did not handle the reallocation correctly.
3739 The affected file is lib/silccore/silcpacket.c.
3741 * Fixed buffer overflow in silc_parse_nickname in the file
3742 lib/silcutil/silcutil.c.
3744 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * make install generates new server keys only if there is not
3749 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3752 Added check that if the NOREPLY is set then we will not send
3753 the away message. This avoids infinite loop of away messages
3754 if both clients are away. The affected file is
3755 lib/silcclient/client_prvmsg.c.
3757 * Fixed client crash if /NICK was given without arguments.
3758 Affected file lib/silcclient/command.c.
3760 * Server does not send the invite list in INVITE command back
3761 to the client if the list was not altered. Added this notion
3762 to the protocol spec as well. Affected file silcd/command.c.
3764 Fixed possible crash in INVITE command by checking the
3765 value of silc_server_get_client_route command.
3767 * Fixed the INVITE notify type handling. The arguments are now
3768 taken in correct order and client does not crash. The affected
3769 file is irssi/src/silc/core/silc-channels.c.
3771 Removed the "Inviting xxx to channel" message from the
3772 client library away and let the application handle it.
3773 Affected file lib/silcclient/command.c. Added that message
3774 to Irssi SILC client's message formats.
3776 * Fixed CMODE command crash in client. It now checks the
3777 amount of arguments correctly and does not crash. The affected
3778 file is lib/silcclient/command.c.
3780 * Do not create new channel automatically in silc_channels_join
3781 but check whether the channel by that name already exists.
3782 Affected file irssi/silc/core/silc-channels.c.
3784 * Do not send the SERVER_SIGNOFF to router if the disconnected
3785 entity was the router. Affected file silcd/server.c.
3787 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3788 SILC client as it was missing from there.
3790 Added the handling of the KICK notify to the Irssi SILC client
3791 as it was missing. Added "you have been kicked" message to
3792 Irssi SILC client's message modules formats.
3794 Added the handing of the KILL notify to the Irssi SILC client
3795 as it was missing. Added the kill message module formats
3798 The affected file is irssi/src/silc/core/silc-channels.c.
3800 * The router did not save the channel mode the server announced.
3801 Affected file silcd/packet_receive.c.
3803 * Fixed a possible crash in INFO command in server. If the
3804 server did not provide the server info it crashed. Affected
3805 file silcd/command.c.
3807 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Fixed the GETKEY command in the server to check also the
3810 global list. Otherwise the GETKEY would not work correctly
3811 in normal SILC server. Affected file silcd/command.c.
3813 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Fixed GETKEY crash, it crashed if the command did not succseed.
3817 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3820 is now real and not just an macro interface to GMP.
3822 Removed the entire GMP from the source tree and imported new
3823 NSS MPI library instead. Reason for removing GMP is that it is
3824 extremely large and compiles extremely slow. The NSS MPI
3825 is only a few files and compiles in less than 10 seconds.
3826 The speed is also about the same as GMP. The MPI is imported
3827 to lib/silcmath/mpi.
3829 If the system has GMP installed we will still use the GMP.
3830 If it is not then the NSS MPI will be compiled.
3832 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Merged a long nickname (127 characters long) crash bugfix from
3835 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3837 * Merged a freed memory reference bugfix from Irssi CVS tree.
3838 Affected file irssi/src/core/commands.c.
3840 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Added the server's public key sving and verification to the
3843 server when performing the SKE. This was missing and the
3844 remote server's (or router's) public key was accepted without
3845 checking whether we have it previously or trust it at all.
3846 Affected file silcd/protocol.c.
3848 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Check in the silc_server_timeout_remote if protocol is active
3851 and make sure that the protocol's final callback is called so
3852 that all memory if freed. Affected file silcd/server.c.
3854 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * silc_server_whois_send_reply crashed the server if the nickname
3857 was 127 characters long. Affected file silcd/command.c.
3859 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Added sanity check to the silc_server_new_client. If the hostname
3862 is provided inside username then check that the provided hostname
3863 really is the same as the resolved one. If the hostname was not
3864 resolved then check it from the public key. Affected file is
3865 silcd/packet_receive.c.
3867 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3868 if the server disconnected us and the connection is not valid
3869 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3871 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3872 the library to the lib/silcutil/silcutil.[ch].
3874 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Close log file after open. Affected file
3877 lib/silcutil/silclog.c.
3879 * Check whether sock == NULL in silc_client_send_packet and return
3880 if it is. Affected file lib/silcclient/silcclient.c.
3882 * Check rec->entry == NULL in the Irssi SILC Client before
3883 sending the channel message. Affecte file is
3884 irssi/src/silc/core/silc-servers.c.
3886 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Merged a splitted window bugfix from Irssi CVS tree. The
3889 affected file is irssi/src/fe-text/textbuffer-view.c.
3891 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3892 It did not print nickname.
3894 * Improved the distributions system a bit.
3896 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3899 irssi/src/fe-text/gui-window.c.
3901 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3902 to in-active server. The affected file is
3903 irssi/src/silc/core/client_ops.c.
3905 * Resolve the client in USERS command reply if the entry does
3906 not have username resolved. The affected file is
3907 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3908 command to WHOIS command to really resolve stuff. The USERS
3909 is not used any more in any critical section so WHOIS can
3910 be used even though it might be slower than IDENTIFY.
3912 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3915 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Changed the protocol API a bit more consistent in the
3918 lib/silccore/silcprotocol.[ch].
3920 * Changed the following headers to ROBODoc format:
3922 lib/silccore/silcpayload.h
3923 lib/silccore/silcprotocol.h
3924 lib/silccore/silcsockconn.h
3926 All core library headers are now formatted.
3928 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Fixed a bug in Irssi SILC client; do not show that you are
3931 server/router operator if you really are not. Affected file is
3932 irssi/src/silc/core/client_ops.c.
3934 * Renamed silc_command_free_payload to silc_command_payload_free.
3935 Affected file lib/silccore/silccommand.h
3937 * Added silcmath.h to include the prototoypes of various routines
3938 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3941 * Changed the following headers to ROBODoc format:
3943 lib/silccore/silcchannel.h
3944 lib/silccore/silccommand.h
3945 lib/silccore/silcid.h
3946 lib/silccore/silcidcache.h
3947 lib/silccore/silcmode.h
3948 lib/silccore/silcnotify.h
3949 lib/silccore/silcpacket.h
3950 lib/silcmath/silcmath.h
3952 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Added checking to the server code not to start the server if
3955 ciphers and stuff are not configured properly. Affected files
3956 silcd/serverconfig.[h] and silcd/server.c.
3958 * Changed the layout of the header files of the public interfaces
3959 in the SILC libraries. The new layout supports ROBODoc
3960 documentation tool (and some others) so that it is easy to create
3961 a library reference manual. All the other headers and source
3962 code must still follow the CodingStyle document. Also source
3963 code must not include these ROBODoc stuffs, only the headers.
3964 Furthermore, all public interface headers must now be named
3965 by using `silc' prefix, example: silcapi.h, silccipher.h.
3966 Some files were renamed due to this. All the other headers
3967 must not be used as public interfaces. I will update the
3968 CodingStyle document later. Changed following headers, so far:
3970 lib/silcclient/silcapi.h
3971 lib/silccore/silcauth.h
3972 lib/silccore/silcprivate.h
3973 lib/silccrypt/silcdh.h
3975 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Removed silc_client_packet_send_flush from the client library
3980 as it is not needed. Affected file lib/silcclient/client.[ch].
3982 * Added printing of message of unresolved authentication method
3983 to the Irssi SILC client. Added it to the module formats.
3984 Removed the same message from the client library.
3986 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Added new distribution feature, DISTLABEL. Every distribution
3989 can define own preprocessor label that can be used in the
3990 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3991 file distributions, acconfig.h.pre and prepare.
3993 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Added Makefile.defines_int to include the actual definitions
3996 for Makefile.defines.in. Tested the new distribution system,
3997 created distributions and tested installation.
3999 * Added AWAY message printing to the Irssi SILC client. Added
4000 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4002 * Added SCONNECT command to call the SILC's CONNECT command.
4003 Cannot use CONNECT directly since Irssi uses that internally.
4004 Affected file irssi/src/silc/core/silc-servers.c.
4006 Added ACTION local command. It is same as ME command but takes
4007 the channel as mandatory argument.
4009 Rewrote some of the Irssi's help files to suite for SILC
4012 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Added Makefile.defines[.in] that should for now on be included
4015 in all Makefile.am file in the source tree. That file includes
4016 all common compilation definitions for SILC source tree.
4018 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Minor changes to the ./prepare script to change the package
4021 name according the distribution name to the configure.in.
4023 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Created new distribution system. Added file `distributions'
4026 that defines all the distributions that can be created out of
4027 the SILC source tree. The ./prepare script now reads that
4028 file to determine how to prepare the distributions. The
4029 first argument to the ./prepare is the name of the distribution
4030 and second is the version of the distribution. If given
4031 without arguments it creates the default (toolkit) distribution
4032 with the default version (defined in ./prepare).
4034 All Makefile.am files that are subject to the distributions
4035 are now named as Makefile.am.pre. These are ./Makefile.am
4036 and lib/Makefile.am. Others may be changed later.
4038 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Added invite list, ban list, some key management and connection
4041 error message printing to module formats in the Irssi SILC client.
4043 * Added new silc_client_set_away_message to set the away message
4044 that is back to the person who sent private message. The
4045 affected file lib/silcclient/silcapi.h and the
4046 lib/silcclient/client_prvmsg.c.
4048 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Fixed the private message sending in the Irssi SILC client,
4051 added local command KEY to the Irssi SILC client.
4053 Added key management and key agreement message formats to the
4054 irssi/src/fe-common/silc/module-formats.[ch].
4056 Added USERS (alias WHO) printing, server/router operator
4057 indication and LIST command printing to the module formats.
4059 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Fixed channel joining notify handling, cumode notify handling
4062 from Irssi SILC client.
4064 * Added SILC specific module-formats to the Irssi SILC client so
4065 that SILC specific message hilighting, colors etc is possible.
4066 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4068 Added channel mode, channel user mode, actions, notices,
4069 whois and whowas printing to the the module-formats.c.
4071 * Fixed a bug in channel deletion in the server. The channel
4072 is not left to the cache even if the channel founder auth mode
4073 is set when there are no users anymore on the channel. Affected
4074 file silcd/server.c.
4076 * The silc_net_localhost now resolves the entire hostname including
4077 the domain name. Affected file lib/silcutil/silcnet.c.
4079 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Changed the ask_passphrase client operation to be ascynchronous.
4082 It has now a completion callback and a context that the
4083 application must call after it has got the passphrase from
4084 the user. Affected files lib/silcclient/silcapi.h,
4085 lib/silcclient/protocol.c, lib/silcclient/command.c and
4088 Added SilcAskPassphrase callback that the application calls
4089 to deliver the passphrase to the library.
4091 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4092 The public key verification and especially a certificate
4093 verification is asynchronous procedure.
4095 Added new SILC_SKE_STATUS_PENDING status to indicate the
4096 request is pending and a callback will be called to finalize
4099 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4100 indicate that remote end did not send its public key (or
4101 certificate), even though we require it. Added check for this
4102 condition in the SKE. This was a security bug, now fixed.
4104 Defined new SilcSKEVerifyCbCompletion callback that is called
4105 when the verification process is completed.
4107 The affected files lib/silcske/silcske_status.h and
4108 lib/silcske/silcske.[ch].
4110 * Changed the verify_public_key client operation to be async
4111 as well. Defined SilcVerifyPublicKey callback that is used to
4112 indicate the success of the public key verification process.
4114 Changed the server and client to use the new async client
4117 * Changed the Irssi SILC client's internal scheduler to be called
4118 twice as many times as it used to be. As a result the client
4119 should be a bit faster now. Affected file is
4120 irssi/src/silc/core/silc-core.c.
4122 * Added support to Irssi SILC client of asynchronous public key
4123 verification and passphrase inquiry. Affected file is
4124 irssi/src/silc/core/silc-core.c.
4126 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Do not say "You have left channel %s" in client library.
4129 Moved it to the application. Affected files are
4130 lib/silcclient/command.c and silc/client_ops.c.
4132 * Fixed silc_client_get_clients. Command context was not
4133 duplicated and was freed memory in the callback. Affected
4134 file lib/silcclient/idlist.c.
4136 * Do not say "you are now talking..." on JOIN command in the
4137 client library. The appliation must handle it.
4139 * Do not say ".. changed topic to" in command reply in the
4140 client libary. The application must handle it.
4142 * Fixed TOPIC command sending in the client library.
4144 * Fixed a memory leak in silc_client_command_free in the file
4145 lib/silcclient/command.c.
4147 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Imported a modified version of Irssi client to the source tree.
4150 The Irssi will be used to create a new client called
4151 Irssi SILC. Imported to irssi/.
4153 Added silc_core_init_finish function to the Irssi. Affected
4154 file irssi/configure.in.
4156 A lot changes in the Makefile.ams around the irssi tree.
4158 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Do not rehash if the new size is same as the old size of the
4161 hash table, in the silc_hash_table_rehash*. The affected file
4162 lib/silcutil/silchashtable.c.
4164 * Replaced hash_table_del_by_context calls from the server
4165 (when channel->user_list and client->channels) to the
4166 hash_table_del as it is sufficient and faster.
4168 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Added silc_hash_table_list, silc_hash_table_get and the
4171 SilcHashTableList structure to provide an alternative way to
4172 traverse the hash table. The affected files are
4173 lib/silcutil/silchashtable.[ch].
4175 * Changed the server's idlist routines to use the hash table
4176 routines to optimize the code.
4178 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Replaced the client entry's `channel' list and channel entry's
4181 `user_list' list to hash tables for optimized lookup. Changed
4182 the code to use the hash table interface around the code.
4183 Affected file lib/silcd/idlist.[ch].
4185 * Added `auto_rehash' boolean argument to the function
4186 silc_hash_table_alloc to indicate whether the hash table should
4187 auto-rehash when it thinks is appropriate time. It will
4188 increase the hash table size if the there is twice as much
4189 entries in the table than the size of the table, and will
4190 decrease the size if there are twice as less entries than
4191 the size of the table.
4193 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4197 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * silc_idcache_purge_by_context deletes the entry now by context
4200 as it is supposed to do. Affected file lib/silccore/idcache.c.
4202 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4203 client is not anymore valid (WHOWAS givens the info) and not
4204 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4206 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Removed the `data' and `data_len' arguments from the ID Cache
4209 interfaces and added `name' argument. ID Cache does not handle
4210 anymore the binary data only a names associated with given ID.
4212 * When hashing a Client ID with silc_hash_id the entire ID is
4213 not hashed anymore, instead only the hash of the Client ID is
4214 hashed. This way we can access the Client ID from the cache
4215 with Client ID but with the hash of the ID (which is a hash of
4216 the nickname) as well without any difference in performance.
4218 Added also silc_idcache_find_by_id_one_ext to do one on one
4219 searching when we have the actual ID. Added also function
4220 silc_hash_client_id_compare. The affected files are
4221 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4223 * When hashing the name associated with a ID it is always done
4224 in lowercase. This way we can access the cache without worrying
4225 about case-sensitivity, even though, for example nicknames are
4228 * Fixed a bug in server with channel message sending. It put
4229 wrong ID type as destination ID. The affected file
4230 silcd/packet_send.c.
4232 * silc_idcache_del_by_context now deletes from all hash tables
4233 by context. Affected file lib/silccore/idcache.c.
4235 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Changed the client library to use the new ID Cache interface.
4238 Changes around the source tree.
4240 * Added silc_hash_table_rehash_ext to rehash with specific
4241 hash function. Affected file lib/silcutil/silchashtable.[ch].
4243 * Added silc_hash_string_compare to compare two strings in the
4244 hash table. Affected file lib/silcutil/silcutil.[ch].
4246 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Added new function silc_idcache_del_by_context into the
4249 lib/silccore/idcache.[ch].
4251 * Changed the server's ID list routines to use the new ID Cache
4252 interface. Changes around the source tree.
4254 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added silc_hash_table_del[_by_context]_ext functions in to the
4257 lib/silcutil/silchashtable.[ch].
4259 Removed silc_hash_table_find_all* routines and added new
4260 silc_hash_table_find_foreach to replace them.
4262 Added silc_hash_table_replace_ext function as extended
4263 replacing function. Separated the simple hash table interface
4264 from the extended hash table interface in the file
4265 lib/silcutil/silchashtable.h.
4267 * Fixed minor bugs and changed it to use some of the new
4268 hash table functions in lib/silccore/idcache.c
4270 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Added new function silc_hash_table_find_all to return all keys
4273 in the hash table by the specified key. As the hash table is
4274 collision resistant it also makes it possible to have several
4275 duplicate keys in the hash table. This function may be used to
4276 find all of the keys from the hash.
4278 Added user_context arguments to the SilcHashFunction,
4279 SilcHashCompare and SilcHashDestructor to deliver user specified
4282 Added new fuctions silc_hash_table_find[_all]_ext to do
4283 extended lookup with specified hash and compare functions and
4284 specified user contexts.
4286 Added new function silc_hash_table_add_ext to add the key
4287 with specified hash function and user context.
4289 Added new function silc_hash_table_foreach to traverse all
4290 entrys in the hash table. Added SilcHashForeach callback
4293 Added new function silc_hash_table_del_by_context to delete
4294 the entry only if the context associated with the key matches.
4296 Affected files are lib/silcutil/silchashtable.[ch].
4298 * Removed silc_hash_[server/client/channel]_id and added just
4299 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4300 silc_hash_id_compare to compare two ID's using as the hash table
4301 comparison function. Added also silc_hash_data to hash
4302 binary data and silc_hash_data_compare to compare it.
4304 * Removed silc_idlist_find_client_by_hash as it is not needed
4305 anymore. Affected file silcd/idlist.[ch].
4307 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4308 to use internally the SilcHashTable. The new ID Cache is a lot
4309 faster than the old one. Some of the ID Cache interface was also
4310 rewritten and obsolete and stupid functions were removed.
4312 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Added entry_count field to the SilcHashTable to keep the number
4315 of the entries in the table. Implemented the function
4316 silc_hash_table_rehash. Added new function
4317 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4319 Fixed a minor bug in silc_hash_table_free.
4321 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4322 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4323 into the lib/silcutil/silcutil.[ch].
4325 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Implemented a collision resistant hash table into the
4328 lib/silcutil/silchashtable[ch]. See the header and the source
4329 for the SilcHashTable API.
4331 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Merged dotconf version 1.0.2 into lib/dotconf.
4335 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Do not compile anything in lib/silcsim/* if the SIM support
4338 is not enabled. The tree should now compile without problems
4341 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Compiled the SILC under cygwin. Compiled and tested briefly
4344 without problems. More tests needed. The SIMs didn't compile
4347 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4349 * Fixed possible crash in silc_get_username in the
4350 lib/silcutil/silcutil.c.
4352 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Fixed a va_arg in silc/client_ops.c.
4356 * Oops, RC5 routines were named AES and caused some problems
4357 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4359 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Added new SilcIDIP structure into the lib/silccore/id.h and
4362 replaced the old `ip' fields from all SILC ID's to that type.
4363 This is a step towards IPv6 support.
4365 The silc_id_get_len takes now the ID as an extra argument.
4366 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4367 both IPv4 and IPv6 based ID's.
4369 The affected files are lib/silccore/id.[ch] and other files
4370 around the tree using these routines.
4372 * Removed the ID length arguments in server from various
4373 silc_server_send_notify_* routines -> they are not needed
4376 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Fixed memory leak in silc_encode_pem_file in the file
4379 lib/silcutil/silcutil.c.
4381 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Check minor version as well in the SKE. Affected files are
4384 silcd/protocol.c and lib/silcclient/protocol.c.
4386 * Added --identifier option to the server so that an identifier
4387 can be when creating the public key for the server. Affected
4388 file is silcd/silcd.c.
4390 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4391 lib/silccrypt/silcpkcs.c.
4393 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Register default ciphers and stuff when using -C option with
4396 the server. Affected file sildc/silcd.c.
4398 * Put back the servers public key filename format, it is better
4399 than the new one. For now, the client keys are saved with the
4400 new filename format. The affected file silc/client_ops.c.
4402 * Implemented the Cipher API for the rest of the ciphers that
4403 did not implement it or implemented it the wrong way.
4405 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Register default ciphers and stuff when using the -S option
4408 in the client. Affected file silc/silc.c. Same also when
4409 creating new key pair with -C option.
4411 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Fixed the silc_verify_public_key client operation function to
4414 save the public keys differently. The fingerprint is now
4415 used as filename and not the hostname. This way also the
4416 client keys are saved uniquely and not with hostnames. The
4417 affected file is silc/client_ops.c.
4419 * Trimmed the silc_hash_fingerprint function to remove extra
4420 whitespaces from the end of the fingerprint. The affected
4421 file is lib/silccrypt/silchash.c.
4425 * Added silc_cipher_register_default function to register all
4426 default ciphers. It can be used when configuration files
4427 does not exist and the application does not want any specific
4428 ciphers in any specific order.
4430 The SilcDList is now used as silc_cipher_list dynamically
4431 allocated cipher list. Removed the static list all together
4432 and now all ciphers must be allocated to the dynamic list.
4433 The silc_cipher_alloc routine was changed to check only the
4436 All silc_cipher_* routines that used to return int returns
4439 The affected files lib/silccrypt/silccrypt.[ch].
4441 * The same thing was done to silc_hash_* as for silc_cipher_*
4442 routines. Affected files lib/silccrypt/silchash.[ch].
4444 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4445 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4446 Added also silc_pkcs_[un]register[_default] functions.
4447 Removed the data_context from the PKCS API.
4449 * Added silc_hmac_register_default function to register default
4450 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4451 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4452 to unregister all hmacs at once.
4454 * Register the default ciphers, hash functions, PKCSs and HMACs
4455 if client's configuration file does not exist. The affected
4458 * The client did not load the hash functions from the SIM
4459 modules at all. Added support for this. Affected file is
4460 silc/clientconfig.c.
4462 * When decoding public key with silc_pkcs_public_key_decode, check
4463 the supported algorithm only if PKCS are registered. Affected
4464 file lib/silccrypt/silcpkcs.c. The same was done with the
4465 silc_pkcs_private_key_decode.
4467 * Fixed the SILC List routines to keep the list always in order.
4468 It used to change the list's order when traversing the list but
4469 not it preserves the order. Affected file lib/trq/silclist.h.
4471 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Added the client library to use the SilcSocketConnection's
4474 reference counter (by silc_socket_dup) to prevent the bug that
4475 the socket object may be freed underneath async operation.
4477 * The name resolv library checking fixes in the configure.in.pre.
4480 * Created new version of the protocol drafts for future
4481 development. The -03 drafts are the ones that will be changed
4482 in the trunk now and the -02 will remain as they are.
4484 * Send list of CUMODE notifys to the router when announcing
4485 the channel users to the router. Affected file silcd/server.c.
4486 If the router receiving channel founder CUMODE for a channel
4487 that already has channel founder it will send CUMODE notify
4488 to the sender to remove the channel founder rights from the
4489 announced client. Affected file silcd/packet_receive.c.
4491 * The CUMODE notify may now use Server ID as well as the entity
4492 who changes the mode. Updated protocool specs.
4494 * Updated INSTALL and README files.
4496 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * New web pages in the http://silc.pspt.fi. The pages was
4503 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Implemented the [DenyConnectin] config section in the server.
4506 Added silc_server_config_denied_conn to check whether incoming
4507 connection is denied. Affected file silcd/serverconfig.[ch].
4509 * Do not check the ports when checking the incoming configuration
4510 data if the port is 0, meaning any. Affected file is
4511 silcd/serverconfig.c.
4513 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Fixed buffer overflow in silc_string_compare in the file
4516 lib/silcutil/silcutil.c.
4518 * Fixed double free in silc_server_command_leave in the file
4521 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Fixed the version checking in the server. Affected file is
4526 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Fixed the configuration data fetching when accepting new
4529 connections in the server. Affected file silcd/server.c.
4531 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Added `sender_entry' argument to the function
4534 silc_server_packet_relay_to_channel so that we can check
4535 whether some destination actually belongs to the same route
4536 the sender belongs (ie, we must not resend the packet to the
4537 sender). Affected file silcd/packet_send.[ch].
4539 * Added `servername' field to the SilcClientEntry in the server
4540 to hold the name of the server where client is from. Affected
4541 file is silcd/idlist.h.
4543 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Moved the channel message encrypting in the router betwen
4546 router connections from silc_server_channel_message to the
4547 silc_server_packet_relay_to_channel since we want to check
4548 whether we have anybody channel before encrypting anything.
4549 Affected files silcd/packet_[receive/send].c.
4551 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Fixed the [AdminConnection] server config section to support
4554 multiple entries. Affected file silcd/serverconfig.c.
4556 * Added support into the server to check the validity of the
4557 incoming connection before executing any KE or authentication
4560 * The connection configuration is now saved to the KE and
4561 connection auth protocol contexts and not fetched anymore in
4562 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4564 * The local hosts listenning address and port is also resolved
4565 now when starting the server. We want to have the socket object
4566 to include the real address and port for the listener. Added
4567 new function silc_net_check_local_by_sock into the files
4568 lib/silcutil/silcnet.[ch].
4570 * Fixed a broadcast bug in server -> do not broadcast if we
4573 * Fixed a routing bug. Do not route broadcast packets ever.
4574 Broadcast packets must be processed always and not routed since
4575 they may be destined to some other host than yourself and thus
4576 would get routed without no good reason. Affected file is
4579 * Added function silc_server_config_is_primary_route to check
4580 whether primary router connection has been configured (a router
4581 configuration that we are initiating). If there is not, we
4582 will assume that there is only two routers in the SILC network
4583 and we will use the incoming router connection as our primary
4584 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4586 * Changed the order of the broadcasting. Broadcast _after_ the
4587 packet has been processed not before. Affected file is
4590 * Fixed a [ClientConnection] parsing bug. The port was never
4591 parsed correctly thus resulting to port 0. Affected file
4592 silcd/serverconfig.c.
4594 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4595 argument and did not set the broadcast packet flag. Affected
4596 file silcd/packet_send.c. Fixed same bug in the function
4597 silc_server_send_notify as well.
4599 * If we receive NEW_ID packet for our own ID in the server, ignore
4602 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Removed the nickname from the Private Message Payload.
4607 Updated the code and the protocol specs.
4609 * Updated protocol specs for submitting to the IETF.
4611 * Tweaked the Random Number Generator a bit. Affected file
4612 lib/silccrypt/silcrng.c. Exported a new function
4613 silc_rng_[global]_add_noise which can be used to add more
4616 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Do not parse packets with different timeout when protocol
4619 is active -> may cause problem with rekey. Affected file
4622 * When server receives signoff notify it must not create
4623 new channel key if the client is on any channels since the
4624 sender of the signoff notify will create it.
4626 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Added printing of error messages during SKE protocol from the
4629 failure packet sent by server during SKE. Affected file
4632 * Removed the client's failure_callback handling with timeout
4633 and handle it immediately when received.
4635 * The SKE library returned wrong type in SUCCESS and FAILURE
4636 packets. They must be 32 bit MSB not 16 bit MSB.
4638 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Ok, rewrote the logic of the re-key and now it seems to work.
4641 I tested it on high traffic with frequent re-keys without
4642 problems. Added hmac_receive (and renamed hmac to hmac_send)
4643 in SilcClientConnection in lib/silcclient/client.h and
4644 in SilcIDListData in silcd/idlist.h. Also, removed the
4645 SilcPacketParserContext's cipher and hmac fields as they are
4646 not needed anymore and actually caused some problems when
4647 the ciphers and hmac's changed underneath the packet parser.
4649 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * If re-key protocol is active then process the incoming packets
4652 synchronously since we must assure that icoming packets encrypted
4653 with the old key is processed before the new keys is set to
4654 use. This is true other packets than for REKEY packets.
4655 Affected file silcd/server.c. The same was done to client library
4656 as well, affected file lib/silcclient/client.c.
4658 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Fixed bug in client and server to accept the force send if
4661 the packet is send from silc_[server/client]_packet_process
4662 function. Otherwise the packets are never delivered, oops.
4664 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Disable force sending of packets when REKEY protocol is active.
4667 We must assure that no packet is sent directly when rekey is
4668 performed. All packets must be sent through packet queue.
4669 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4670 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4671 function is silc_[server/client]_packet_send_real to check
4674 * Replaced the SIM paths from example config files to
4675 /usr/local/modules. Also, make install creates now
4676 /usr/local/silc/logs directory to hold all the SILC server
4679 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Made the configure.in.pre work on Solaris. Patch by salo.
4683 * Made all ciphers compatible with non-x86 machines. Defined
4684 CBC mode macros into lib/silccrypt/ciphers_def.h.
4686 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Fixed the make install.
4690 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * When MAC computation fails the silc_packet_decrypt returned 0
4693 even though it was supposed to return -1. Fixed this. The
4694 affected file is lib/silccore/silcpacket.c.
4696 * Do not replace the config files in /etc/silc (in make install)
4697 if they already exist. Affected file ./Makefile.am.
4699 * Do not send re-key packets immediately but through packet queue.
4700 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4702 * Changed silc_net_check_host_by_sock to return FALSE if the
4703 IP/DNS could not be resolved. Though, it returns the IP address
4704 now even if it could not resolve it (but returns also FALSE).
4705 Affected file lib/silcutil/silcnet.[ch].
4707 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Added silc_pkcs_decode_identifier to decode the public key's
4710 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4711 Added also silc_pkcs_free_identifier. Added also new context
4712 SilcPublicKeyIdentifier.
4714 * Added -S option to the silc client. It is used to dump the
4715 contents of the specified public key file.
4717 * Changed the PKCS api to return the public key length when
4718 setting the public key.
4720 * Fixed a fatal bug in the public and private key file loading.
4721 Affected file lib/silccrypt/silcpkcs.c.
4723 * Execute the packet parsing for client with zero (0) timeout
4724 if the protocol is active. Affected file silcd/server.c.
4726 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Made the key generation options to the silcd program. Added
4729 -C option, equivalent to client's option.
4731 * Added new [ServerKeys] config section to the server. It
4732 configures the server's public and private key.
4734 * Defined generic Public Key Payload into the protocol
4735 specification to send specific type of public keys and
4738 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4739 public key or certificate.
4741 * Implemented the GETKEY command to the server and to the
4742 client library and on user interface.
4744 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Made preliminary `make install' work.
4748 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Added SilcServerRekey context into silcd/idlist.h.
4752 * Added the PFS support as defined in the specification to the
4753 SKE protocol. Affected files lib/silcske/*.c.
4755 * Added `ske_group' field to the SilcServerRekey context to hold
4756 the number of the SKE group that is used with PFS in re-key.
4757 Affected file silcd/idlist.h.
4759 * Added PFS re-key support to the server. Affected file is
4762 * Added silc_protocol_cancel to cancel execution of the next
4763 state of the protocol. Affected file is
4764 lib/silccore/silcprotocol.[ch].
4766 * Added the re-key support with and without PFS to the client
4767 library. Re-key is performed once in an hour, by default.
4769 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4770 Added silc_client_rekey_callback and silc_client_rekey_final.
4771 Affected files are lib/silcclient/protocol.[ch] and
4772 lib/silcclient/client.[ch].
4774 * Removed the `hmac_key' and `hmac_key_len' fields from the
4775 SilcClientConnection structure; not needed. Affected file is
4776 lib/silcclient/client.h.
4780 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Do not ask whether user wants to use the negotiated private key
4783 for private messages, just use it. Affected file is
4784 silc/local_command.c.
4786 * Added `send_enc_key' and `enc_key_len' fields to the
4787 SilcIDListData structure since they are needed in the re-key
4788 phase. Affected file is silcd/idlist.[ch].
4790 * Implemented the simple re-key protocol into the server.
4791 Affected files silcd/server.c and silcd/protocol.[ch]. The
4792 re-key will be performed once in an hour, by default.
4794 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4795 Added silc_server_rekey, silc_server_rekey_callback and
4796 silc_server_rekey_final.
4798 * Removed Tunneled flag from the protocol. Updated the code
4799 and the specifications.
4801 * Adde `pfs' field to the SilcIDListData to indicate whether
4802 the PFS is to be performed in the re-key. Affected file is
4805 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4808 int64 of at least the xintXX size. If void * is less that 4
4809 bytes uint32 * will be used. Defined bool as boolean.
4811 * Changed _ALL_ unsigned long and unsigned int to uint32,
4812 unsgined short to uint16 in the source tree.
4814 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4815 not handle clients that has entry->data.registered == FALSE.
4816 They are not in the network anymore. Affected file is
4819 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Implemented the sending of the SERVER_SIGNOFF notify in the
4822 server. Affected file is silcd/server.c.
4824 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4825 Added also silc_notify_payload_encode_args into the
4826 lib/silccore/silcnotify.[ch].
4828 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4829 Affected file silcd/packet_receive.c.
4831 * Implemented the SERVER_SIGNOFF notify handling in the client
4832 library. Affected file lib/silcclient/client_notify.c. Also,
4833 implemnted the printing of the SERVER_SIGNOFF info to the
4834 application. Affected file silc/client_ops.c.
4836 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4837 if the deleting was successful. Affected file silcd/idlist.[ch].
4839 * Added support for public key authentication in the connection
4840 authentication protocol in the client library. Affected file
4841 lib/silcclient/protocol.c.
4843 * Changed the server's silc_idlist_get_clients_by_* interface
4844 to support already allocated array so that new entries may be
4845 added to pre-allocated array. Affected file silcd/idlist.[ch].
4846 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4847 and command replies.
4849 * All command reply functions in the server now calls the
4850 pending command callback even if error occured. This way the
4851 error will be delivered to the client as well. Affected files
4852 silcd/command.c and silcd/command_reply.c.
4854 * Fixed INFO command to return local server's info if no server
4855 was provided. Affected file lib/silcclient/command.c.
4857 * Removed RESTART command for good. Updated the code and the
4860 * Rewrote parts of the task system. It is a bit simpler now.
4861 Removed unsued task priorities. The affected files are
4862 lib/silcutil/silctask.[ch].
4864 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4866 * Moved the USERS printing from the library to the application.
4867 Affected files lib/silcclient/command.c and silc/client_ops.c.
4869 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Added channel key re-key support. The re-key is perfomed
4874 only by the router and is done once in an hour. Added `rekey'
4875 field to the SilcChannelEntry in the server. Affected files
4876 silcd/server.c and silcd/idlist.h.
4878 * Added silc_task_unregister_by_context into the file
4879 lib/silcutil/silctask.[ch].
4881 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Added SILC_UMODE_GONE mode to indicate when the client is not
4884 present in the SILC network. Added also support to the local
4885 command AWAY that will set this mode. Added support of showing
4886 "xxx is gone" in WHOIS command. The USERS command shows the
4887 gone status as well.
4889 * Fixed setting server and router operator privileges in the
4890 server's UMODE command. Affected file silcd/command.c.
4892 * Merged the SKE KE1 and KE2 payloads into one payload. The
4893 new KE payload is equivalent to the old KE2 payload.
4895 Cleaned up the SKE Start Payload parsing. It now uses the
4896 simple buffer unformatting to do the parsing. A lot faster
4899 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4900 to the SKE that is used to indicate whether both of the SKE
4901 parties should perform authentication. By default only the
4902 responder performs authentication. By setting this flag also
4903 the initiator must do authentication. By default it is unset
4904 since in normal SKE case, client to server connection, only
4905 the responder should do authentication. When doing SKE between
4906 two clients both should perform authentication. Updated the
4907 code and the protocol specs.
4909 * A little fix to IDENTIFY command in the server. Search the
4910 client first by hash not nickname. Affected file is
4913 * Fixed the silc_client_close_connection to support closing
4914 the client to client connections wihtout deleting too much
4915 data. Affected file lib/silcclient/client.c.
4917 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4918 are received if protocol used to be active but is not anymore
4919 the application would crash due to NULL pointer dereference.
4920 Affected files silcd/server.c and lib/silcclient/client.c.
4922 * Added `hash' field to the SilcClientConnection to include
4923 the hash function negotiated in the SKE protocol.
4925 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4926 to set the channel founder authentication data. A client can
4927 claim the founder rights later by providing the authentication
4928 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4929 This way the channel founder can regain the channel founder
4930 privileges even it is left the channel. This works only on
4931 local server and the client must be connected to the same
4932 server to be able to regain the founder rights. Updated the
4933 protocol specs accordingly.
4935 Added support to the CMODE command in the client to set the
4936 founder auth data. Read the README to see how to set it.
4938 Added support to the CUMODE command to claim the founder
4939 rights. Read the README to see how to do it.
4941 Added support for the founder authentication to the Channel
4942 Entry in the server. Affected file silcd/idlist.h.
4944 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4945 server's CMODE command. Affected file silcd/command.c.
4947 * Added the following new functions into lib/silccore/silcauth.[ch]:
4948 silc_auth_get_method and silc_auth_get_data.
4950 * The server now saves the remote hosts public key to the
4951 SilcIDListData pointer. Affected file silcd/protocol.c.
4953 * The normal server now does not remove the channel entry from
4954 the cache if the founder authentication data is set. It used
4955 to remove it if the founder was the last one on the channel on
4956 the server and left the channel. The auth data is saved and
4957 if the channel is re-joined later the old entry is used with
4958 the old auth data. Affected files silcd/command_reply.c and
4961 * Removed the `pkcs' field from the SilcIDListData structure
4962 in the server; it is not used. Affected file silcd/idlist.h.
4964 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Fixed packet processing on slow links. Partial packets were
4967 never re-processed because the incoming data buffer was cleared
4968 by the application. Application must not directly clear the
4969 sock->inbuf, the packet processing routines handle it. Fixed
4970 this in client library and in server.
4972 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Fixed the WHOIS and IDENTIFY send reply function to really
4975 check whether to send list or just one entry. Affected file
4978 * Cleaned up the LEAVE command's channel key distribution. The
4979 affected file silcd/command.c.
4981 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4982 can enforce the channel mode as well. In that case the ID
4983 includes the ID of the server. The code now enforces the
4984 mode change if the router have different mode than the server.
4986 * The notify client operation with CMODE_CHANGE notify can now
4987 return NULL client_entry pointer if the CMODE was not changed
4988 by client. Application must check for this.
4990 * Added <Server ID> argument to INFO command to support server
4991 info fetching by Server ID.
4993 * Added silc_server_announce_get_channel_users to get assembled
4994 packets of channel users of the specified channel. Affected
4995 file silcd/server.[ch].
4997 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4998 was freed underneath the ID Cache.
5000 * Re-announce clients when the server received CHANNEL_CHANGE
5001 notify from the router. Affected file silcd/packet_send.c.
5003 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5006 crashed since it did not handle the fact that there is no cipher
5007 called "3" and didn't check the error condition. Now fixed.
5009 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5010 flag. It can be used to send message requests.
5012 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Implemented the RESTART command in the client.
5016 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5017 notice type messages. Added notice printing to the user
5020 * The channel keys are not re-generated if the channel's mode
5021 is PRIVKEY, ie private key on the channel exists. Affected
5022 files silcd/server.c and silcd/command.c.
5024 * Fixed a little bug in channel message delivery when channel
5025 private keys are set in the server. Affected file is
5026 silcd/packet_send.c.
5028 * Changed the setting on channel->on_channel = TRUE from the
5029 silc_client_save_channel_key to the JOIN command reply. The
5030 key payload is not received if the private channel key is set.
5031 Affected file lib/silcclient/command_reply.c and the
5032 lib/silcclient/client_channel.c.
5034 * When the CMODE_CHANGE notify is sent and the channel private
5035 key mode is removed the channel key must be re-generated in
5036 other cells as well. Added this support for the router in the
5037 silcd/packet_receive.c.
5039 * Added new local command NOTICE to send notice message on
5040 channel. Affected file silc/local_command.[ch].
5042 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Added new local command ME to the client. It is used to send
5045 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5046 some action. Affected file silc/local_command.[ch].
5048 * Changed channel_message and private_message client operations
5049 to deliver the message flags to the application. Added also
5050 the `flags' arguments to the silc_client_send_channel_message
5051 and silc_client_send_private_message functions. Affected file
5054 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Redefined the Private Message Payload to support private message
5057 keys and to support the new private message flags. Updated
5058 the protocol specs. Flags makes it possible to have for example
5059 CTCP style messages.
5061 * Added new type SilcPrivateMessagePayload and defined an API
5062 for it in the lib/silcclient/silcprivate.[ch].
5064 * Tested private message private keys successfully. Tested the
5065 private message key set, unset and list commands with the new
5068 * Redefined the Channel Message Payload to include the channel
5069 message flags (equal with private message flags) to support
5070 for example CTCP style messages.
5072 * Defined some of the message (for channel and private message)
5073 flags. Updated the protocol specs and added the flags to the
5074 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5076 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Added SilcKeyAgreementStatus type to the key agreement routines
5079 to indicate the current status and error if one occured.
5080 The status types are defined in the lib/silcclient/silcapi.h.
5082 * Added new local command KEY that is used to set and unset private
5083 keys for channels, set and unset private keys for private messages
5084 with remote clients and to send key agreement requests and
5085 negotiate the key agreement protocol with remote client. The
5086 key agreement is supported only to negotiate private message keys,
5087 it currently cannot be used to negotiate private keys for channels,
5088 as it is not convenient for that purpose.
5090 * Fixed a minor pending callback setting bug in the function
5091 silc_client_get_client_by_id_resolve, now the function works.
5092 Affected file lib/silcclient/idlist.c.
5094 * Added function silc_net_get_local_port to get local bound
5095 port by socket. Added to lib/silcutil/silcnet.[ch].
5097 * Added `sockets' and `sockets_count' fields to the SilcClient
5098 object. They hold the sockets of the listenning sockets in
5099 the client. Listenning sockets may be for example the key
5100 agreement server. Affected file lib/silcclient/client.[ch].
5101 Added functions the silc_client_add_socket and the
5102 silc_client_del_socket. They are exported to the application
5105 * Added ~./silc/clientkeys to support other client's public keys.
5107 * Renamed verify_server_key client operation to verify_public_key
5108 and added one argument to indicate the type of the connection
5109 (server, client etc.).
5111 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Added silc_server_connection_auth_request to handle the
5114 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5115 silcd/packet_receive.[ch].
5117 * Added silc_server_send_connection_auth_request into the
5118 silcd/packet_send.c to send the connection auth request packet.
5120 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5123 * Fixed the public key authentication in responder side in the
5124 server. The `auth_data' pointer includes the SilcPublicKey
5125 not the path to the public key. Affected file silcd/protocol.c.
5127 * Implemented the public key authentication in the initiator side
5128 in the server. Affected file silcd/protocol.c.
5130 * Removed the [RedirectClient] config section from the server
5131 configuration. Is not needed and I don't want to implement it.
5133 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Cleaned up the CMODE command in the server. It now works
5136 correctly and supports all the modes defined in the protocol.
5137 Affected file is silcd/command.c.
5139 * Added `hmac_name' field to the SilcChannelEntry in the server
5140 to hold the default HMAC of the channel. It can be set when
5141 creating the channel (with JOIN command). Affected files
5144 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5145 type to indicate the change of the current cipher and hmac
5146 on the channel. Client can safely ignore the <cipher> argument
5147 (if it chooses to do so) since the CHANNEL_KEY packet will
5148 force the channel key change anyway. The <hmac> argument is
5149 important since the client is responsible of setting the new
5150 HMAC and the hmac key into use.
5152 * Fixed the CMODE command in the client library as well.
5154 * Tested CMODE command in router environment successfully.
5156 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * Show the version of the remote client (or server) when connecting
5159 to the server. It is logged to the log file. Affected file
5160 is silcd/protocol.c.
5162 * Fixed the KILLED notify handling in the client library. The
5163 client must be removed from all channels when receiving the
5166 Also, do not remove the client entry when giving the KILL
5167 command but when the KILLED notify is received.
5169 * Removed silc_idlist_find_client_by_nickname from the server.
5170 Not needed anymore. Affected files silcd/idlist.[ch].
5172 * Implemented the CHANNEL_CHANGE notify type handling to the
5173 server. Affected file silcd/server.c.
5177 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * Added silc_server_send_notify_invite to send the INVITE
5180 notify between routers.
5182 * Implemented the INVITE command correctly to the server.
5184 * Implemented the INVITE notify type handling in the server.
5186 * Implemented the INVITE command to the client library and on the
5189 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Added function silc_server_get_client_resolve to find the
5192 client entry by ID from all ID lists and then resolve it
5193 (using WHOIS) if it cannot be found. Affected file is
5196 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Implemented the BAN command to the client library.
5200 * The JOIN command in the server now checks the invite list
5203 * Changed the silc_command_reply_payload_encode_va and the
5204 silc_command_payload_encode_va to support that if argument is
5205 NULL it ignores and checks the next argument. Affected file
5206 lib/silccore/silccommand.c.
5208 * Added silc_server_send_notify_ban to send the BAN notify
5209 type between routers.
5211 * Chaned the silc_notify_payload_encode to support that if
5212 argument is NULL it ignores and checks the next argument.
5213 Affected file lib/silccore/silcnotify.c.
5215 * Tested ban lists in router environment successfully.
5217 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * Implemented BAN command to the server, in silcd/command.[ch].
5221 * Removed the BAN and INVITE_LIST modes from the CMODE command
5224 * Added function silc_string_match to regex match two strings.
5225 Affected files lib/silcutil/silcutil.[ch].
5227 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Redefined parts of the SilcChannelEntry in the server to support
5230 the new ban and invite lists.
5232 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Redefined the INVITE command. The same command can be used to
5235 invite individuals to the channel but also to manage the invite
5236 list of the channel (to add to and remove from the invite list).
5237 Updated the protocol specs.
5239 * Added new command SILC_COMMAND_BAN that can be used to manage
5240 the ban list of the channel. Updated the protocol specs.
5242 * Removed the channel modes: the SILC_CMODE_BAN and the
5243 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5244 in the CMODE command. The equivalent features are now available
5245 using INVITE and BAN commands. Updated the protocol specs.
5247 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5248 in the network about change in the current ban list. The notify
5249 type is not used by the client.
5251 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5252 support the invite lists.
5254 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added new function silc_string_regexify that converts string
5257 including wildcard characters into regex string that can
5258 be used by the GNU regex library. Added into the file
5259 lib/silcutil/silcutil.[ch].
5261 Added silc_string_regex_combine to combine to regex strings
5262 into one so that they can be used as one regex string by
5263 the GNU regex library. Added into the file
5264 lib/silcutil/silcutil.[ch].
5266 Added silc_string_regex_match to match two strings. It returns
5267 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5269 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Imported GNU regex to the soruce tree into lib/contrib.
5272 Fixed some compiler warning from the regex.c.
5274 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Fixed MOTD command in the server to work in router environment.
5278 * Fixed the MOTD command in the client library to support
5279 the server argument in the command.
5281 * Added `nickname_len' argument to the silc_idlist_add_client
5282 in the server, as the `nickname' argument may be binary data
5285 * Added silc_idlist_get_channels to return all channels from
5288 * Implemented LIST command to the server. Affected file is
5291 * Implemented the LIST command to the client library and on the
5294 * Added [<user count>] argument to the LIST command reply.
5295 With private channels the user count is not shown.
5297 * Updated TODO and README.
5299 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * The client entry's data.registered must be TRUE even with
5302 global client entry on global client list. The data.registered
5303 is used to check whether the client is anymore in the network,
5304 for example with WHOWAS command so it must be valid.
5306 * Fixed the WHOWAS command in the server. It now actually works
5307 in router environment. Added function into silcd/command_reply.c
5308 silc_server_command_reply_whowas_save.
5310 * Added silc_idlist_purge function to the silcd/idlist.c
5311 to periodically purge the ID Cache.
5313 * Fixed INFO command in the server. It works now in router
5314 environment. Added <server name> argument to the INFO command
5315 reply. Updated the protocol specs.
5317 * Fixed minor bug in silc_idcache_purge to not purge if the
5318 expire value is zero.
5320 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5321 they were buggy because of the WHOWAS information.
5323 * Fixed local command MSG to handle the async resolving of
5324 the remote client properly. It used to fail the first MSG.
5325 Affected file silc/local_command.c.
5327 * Added `data_len' field to SilcIDCache context.
5329 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Update TODO. Todo in commands in the server.
5333 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5336 used by routers as broadcast packet to inform other routers
5337 about the changed user mode.
5339 Implemented the notify handling in the server. Affected file is
5340 silcd/packet_receive.c. Added the function
5341 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5343 * Added new generic Channel Payload and deprecated the New Channel
5344 Payload. The New Channel Payload is now the generic Channel
5347 * Added new argument `mode' to the silc_server_send_new_channel
5348 as it is required in the Channel Payload now.
5350 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5351 and created a new and real SilChannelPayload to represent the
5352 new generic Channel Payload. Implemented the encode/decode
5353 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5355 * Added silc_server_get_client_channel_list to return the list
5356 of channels the client has joined for WHOIS command reply.
5357 Affected file silcd/server.[ch].
5359 * Implemented the channel list sending in the WHOIS command reply
5360 in server and in the client.
5362 Implemented the channel list displaying on the user interface
5363 as well. Affected file silc/client_ops.c.
5365 * Added silc_channel_payload_parse_list to parse list of Channel
5366 Payloads. It returns SilcDList list of SilcChannelPayloads.
5367 Client for example can use this function to parse the list of
5368 channels it receives in the WHOIS command reply. The caller
5369 must free the list by calling silc_channel_payload_list_free.
5370 Affected files lib/silccore/silcchannel.[ch].
5372 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added one new argument <user mode> to the WHOIS command reply
5375 to return the mode of the user in SILC. Updated the protocol
5378 Implemented it to the server and client.
5380 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Fixed the mode printing on the user interface on joining.
5383 Affected file silc/client_ops.c.
5385 * Implemented the UMODE command and user modes in general to the
5386 client library and to the user interface.
5388 * Implemented the UMODE command to the server.
5390 * The server now sends UNKNOWN_COMMAND error status if client sends
5391 unknown command. Affected file silcd/command.c.
5393 * All server commands now handle the command identifier the right
5394 way when sending the command reply to the client. The client can
5395 use to identify the command replies with the identifier.
5397 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Added silc_server_get_client_route to resolve the route to
5400 the client indicated by the client ID. Affected file is
5403 * Added silc_server_relay_packet as general function to relay
5404 packet to arbitrary destination. This deprecates functions
5405 like _send_private_message_key, _relay_notify etc. Affected
5406 file is silcd/packet_send.[ch].
5408 Removed silc_server_send_key_agreement,
5409 silc_server_send_private_message_key and
5410 silc_server_packet_relay_notify functions from the file
5411 silcd/packet_send.[ch].
5415 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5416 server. Affected file silcd/packet_receive.[ch].
5418 * Implemented the KILL command to the client. Implemented the
5419 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5420 Affected files lib/silcclient/command[_reply].c and
5421 lib/silcclient/client_notify.c. Implemented the KILL notify
5422 printing in the user inteface.
5424 * Fixed a lot silc_parse_nick memory leaks from the client
5425 library in the file lib/silcclient/command.c.
5427 * Changed the silc_server_send_notify_on_channels's `sender'
5428 argument from SilcSocketConnection to SilcClientEntry to
5429 check the sender as entry and not as connection object and not
5430 to send to the client provided as argument. The affected file
5431 is silcd/packet_send.[ch].
5433 * The notify packets that are destined directly to the client used
5434 to not to be processed by the server. Now changed that and the
5435 server processes all notify packets. After relaying the packet
5436 to the client the notify packet is processed in the server.
5438 * The silc_server_free_client_data now checks whether there is
5439 pending outgoing traffic for the client and purges the data to
5440 the network before removing the client entry.
5442 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5445 an client is killed from the SILC Network. Updated the protocol
5448 Added new function silc_server_send_notify_killed to the
5449 silcd/packet_send.[ch].
5451 * Added function silc_server_packet_relay_notify to relay notify
5452 packets that are destined directly to a client. In this case
5453 the server does not process the notify packets but merely relays
5454 it to the client. Affected file silcd/packet_send.[ch].
5456 Added also silc_server_packet_process_relay_notify to check
5457 whereto relay the notify. Affected file is
5458 silcd/packet_receive.[ch].
5460 * Implemented the KILL command to the server.
5464 * Added the backup schema desgined last fall to the protocol
5465 specs for everyone to see. The specification is in the
5466 *-spec-xx.txt draft and the packet type definitions for the
5467 backup routers is in *-pp-xx.txt draft. Thusly, added also
5468 new packet type SILC_PACKET_CELL_ROUTERS.
5470 * A big security problem in the implementation discovered. The
5471 signoff of an client did not cause new channel key generation
5472 which it of course should've done. The channel keys must be
5473 always re-generated when client leaves (or signoffs) the channel.
5474 The silc_server_remove_from_channels funtion now handles
5475 the channel key re-generation.
5477 * Added `sender' argument to the silc_server_send_notify_on_channels
5478 to not to send the client provided as argument. Affected file
5479 silcd/packet_send.[ch].
5481 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Implemented OPER and SILCOPER commands into the server and
5486 * Added silc_auth_verify and silc_auth_verify_data to verify
5487 the authentication directly from the authentication payload.
5488 It supports verifying both passphrase and public key based
5489 authentication. Affected file lib/silccore/silcauth.[ch].
5491 * Added `hash' field to the SilcIDListData structure. It is the
5492 hash negotiated in the SKE protocol. Affected file is
5495 * Slight redesigning of the SilcAuthPayload handling routines.
5496 Do not send SilcPKCS but SilcPublicKey as argument.
5498 * Implemented the public key authentication support to the
5499 serverconfig. The public key is loaded from the provided path
5500 and saved as authentication data to void * pointer. Thus,
5501 changed the unsigned char *auth_data to void *auth_data;
5503 * Fixed SHUTDOWN command to send the reply before the server
5504 is shutdown. :) Affected file silcd/command.c.
5506 * Fixed fatal bug in CONNECT command. The hostname was invalid
5507 memory and server crashed. Affected file silcd/command.c.
5509 * Fixed fatal bug in CLOSE command. The server_entry became
5510 invalid but was referenced later in the command. Affected file
5513 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Fixed fatal bug in failure packet handling. Server ignored
5516 the failure and thus crashed when it came.
5520 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5523 that the command may be executed only once in (about) 2 seconds.
5524 The old SILC_CF_LAG flag is same but allows command bursts up
5525 to five before limiting.
5527 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5528 server code. Various commands now includes the CF_LAG_STRICT
5529 flag to disallow any kind of miss-use of the command.
5531 * Fixed the silc_buffer_unformat to not to allocate any data
5532 if the length of the data is zero. It used to allocate the
5533 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5535 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Changed the format of AdminConnection configuration section
5538 in the server. Added username of the admin to the format.
5539 Affected files silcd/serverconfig.[ch].
5541 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5542 to return admin configuration data by host, username and/or
5545 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Implemented WHOWAS command to the server. Added the functions:
5549 silc_server_command_whowas_parse,
5550 silc_server_command_whowas_send_reply,
5551 silc_server_command_whowas_from_client and
5552 silc_server_command_whowas_from_server
5554 * Added <Client ID> argument to the WHOWAS command reply. Updated
5555 the protocol specs accordingly.
5557 * Implemented WHOWAS command and command_reply to the client
5560 Implemented the WHOWAS printing on the user interface.
5562 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Added new argument to the WHOWAS command reply, the real name.
5565 It is an optional argument. Updated the protocol specs.
5567 * Added SilcIDCacheDestructor callback that is registered when
5568 the SilcIDCache is allocated. The callback is called when
5569 an cache entry in the ID Cache expires, or is purged from the
5570 cache. Added into lib/silccore/idcache.[ch].
5572 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5573 to destruct the client entries when the cache entry expires.
5574 Other ID Cache's in server and in the client library ignores
5577 * If the ID Cache entry's `expire' field is zero then the entry
5578 never expires. Added boolean `expire' argument to the
5579 silc_idcache_add function in the lib/silccore/idcache.[ch].
5580 If it is TRUE the default expiry value is used.
5582 * Added silc_server_free_client_data_timeout that is registered
5583 when client disconnects. By default for 5 minutes we preserve
5584 the client entry for history - for WHOWAS command.
5586 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Added support to the server to enforce that commands are not
5589 executed more than once in 2 seconds. If server receives
5590 commands from client more frequently, timeout is registered
5591 to process the commands. Affected file silcd/command.c.
5592 Added new function silc_server_command_process_timeout.
5594 * Changed NICK_NOTIFY handling in client library to check that
5595 if the client's nickname was changed, so there is no need to
5596 resolve anything from the server.
5598 * Removed error printing from the WHOIS and IDENTIFY commands.
5599 If error occurs then it is ignored silently in the client library.
5600 The application, however, may map the received error to
5601 human readable error string. The application currently maps
5602 the NO_SUCH_NICKNAME error to string.
5604 * Made the command status message public to the application. Moved
5605 them from lib/silcclient/command_reply.c to
5606 lib/silcclient/command_reply.h. The application can map the
5607 received command status to the string with the
5608 silc_client_command_status_message function.
5610 * Added check to the server to check that client's ID is same
5611 as the Source ID in the packet the client sent. They must
5614 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added dist-bzip hook to the Makefile.am to make bzip2
5617 compressed distributions.
5619 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Server now enforces the maximum length for the nickname and
5622 the channel as protocol specification dictates. 128 bytes for
5623 nickname and 256 bytes for channel name.
5625 * Moved the WHOIS printing to the application. The client libary
5626 does not print out the WHOIS information anymore, the application
5627 must do it. Renamed silc_client_command_reply_whois_print to
5628 the silc_client_command_reply_whois_save.
5630 The client's idle time is also sent to the application now, and
5631 the idle is shown on screen.
5633 * Added silc_client_command_reply_identify_save to save the
5634 received IDENTIFY entries.
5636 * Do not check for channel private keys in message sending and
5637 reception if the channel does not have the PRIVKEY mode set.
5638 Affected file lib/silclient/client_channel.c.
5640 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5643 just surfaced after chaning the JOIN procedure.
5645 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Added silc_client_get_clients_by_list to get client entries
5648 from Client ID list, that is returned for example by JOIN
5649 and USERS command replies. The application should use this
5650 function for example when JOIN command reply is received to
5651 resolve the clients already on the channel (library does not
5652 do that anymore as USERS command reply is not used in the JOIN
5653 procedure anymore). Affected files lib/silcclient/silcapi.h and
5654 lib/silcclient/idlist.c.
5656 * JOIN command reply and USERS command reply returns now SilcBuffer
5657 pointers instead of unsigned char pointers when returning
5658 the client list and mode list.
5660 * Added <Client ID> argument to the JOIN command reply, mainly
5661 for the server to identify for which client the command was
5662 originally sent. Updated protocol specs accordingly.
5664 * Added SilcDlist private_key pointer to the SilcChannelEntry
5665 in the client to support the channel private keys. Affected
5666 file is lib/silcclient/idlist.h.
5668 * Added SilcChannelPrivateKey argument to the function
5669 silc_client_send_channel_message so that application can choose
5670 to use specific private ke if it wants to. If it is not provided,
5671 the normal channel key is used, unless private keys are set.
5672 In this case the first (key that was added first) is used
5673 as the encryption key.
5675 * Implemented the support for channel private key handling.
5676 Implemented the following functions:
5678 silc_client_add_channel_private_key,
5679 silc_client_del_channel_private_keys,
5680 silc_client_del_channel_private_key,
5681 silc_client_list_channel_private_keys and
5682 silc_client_free_channel_private_keys
5684 Affected file lib/silcclient/client_channel.c.
5686 * Added the support for the private keys in the channel message
5687 sending and encryption and in the message reception and
5688 decryption. Affected funtions are
5689 silc_client_send_channel_message and silc_client_channel_message.
5691 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Added SKE's key verify callback to the client library's
5694 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5696 * Removed the statement that server (or router) must send USERS
5697 command reply when joining to the channel so that the client
5698 knows who are on the channel. Instead, the client list and
5699 client's mode list is now sent in the JOIN command reply to the
5700 client who joined channel. This is better solution.
5702 * Added function silc_server_get_users_on_channel and function
5703 silc_server_save_users_on_channel to the silcd/server.[ch].
5705 * Removed function silc_server_command_send_users from the
5708 * Do not show topic on the client library anymore. The topic is
5709 sent in the command reply notify to the application and the
5710 application must show the topic now.
5712 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Added client searching by nickname hash into the IDENTIFY and
5715 WHOIS commands in the server as they were clearly missing from
5716 them. Affected file is silcd/command.c.
5718 * Fixed a bug in private message receiving in the client library.
5719 The remote ID was freed and it wasn't supposed, now it is
5722 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Minor fix to the channel payload; allocate the data area, as it
5725 needs to be of specific length.
5727 * If the key agreement port is zero then the operating
5728 system will define the bound port. Affected files are
5729 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5731 * Added new function silc_channel_payload_decrypt into the file
5732 lib/silccore/silcchannel.[ch].
5734 * Moved the channel message etc, check from silc_packet_decrypt
5735 to applications. The library calls now a generic
5736 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5737 when the packet is either normal or special. This was done to
5738 allow more wide range of checking that was not allowed when
5739 the code was in library. Now applications can do virtually any
5740 checks to the packet and return to the library the decision how
5741 the packet should be processed. Affected files are
5742 lib/silccore/silcpacket.[ch].
5744 Added silc_server_packet_decrypt_check to the server and
5745 silc_client_packet_decrypt_check to the client library.
5747 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5748 to send with specified source and destination information.
5750 * Channel message delivery between routers was broken after the
5751 channel key distribution was fixed earlier. The channel key
5752 was used be to distributed to other routers as well which is not
5753 allowed by the protocol. Now this is fixed and channel keys
5754 really are cell specific and the channel message delivery between
5755 routers comply with the protocol specification.
5757 * Fixed various commands in server to check also the global list
5758 for the channel entry and not just the local list. The affected
5759 file silcd/command.c.
5761 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Added assert()s to buffer formatting and unformatting routines
5764 to assert (if --enable-debug) when error occurs. Affected
5765 file: lib/silcutil/silcbuffmt.c.
5767 * Changed to auto-reconnect to check whether the remote host is
5768 router and register the re-connect timeout if it is. It used
5769 to check that whether we are normal server, but router must do
5770 auto-reconnect with another router as well. Affected file
5773 * Removed the [<key len>] option from CMODE command as the cipher
5774 name decides the key length, nowadays. See the defined ciphers
5775 from the protocol specification.
5777 * Added [<hmac>] option to the CMODE command to define the HMAC
5778 for the channel. Added SILC_CMODE_HMAC channel mode.
5780 * Added [<hmac>] option for the JOIN command so that user can
5781 select which HMAC is used to compute the MACs of the channel
5784 * Added Hmac field to the Channel Message Payload. The integrity
5785 of plaintext channel messages are now protected by computing
5786 MAC of the message and attaching the MAC to the payload. The
5787 MAC is encrypted. Now, it is clear that this causes some
5788 overhead to the size of the packet but rationale for this is that
5789 now the receiver can verify whether the channel message decrypted
5790 correctly and also when private keys are set for the channel the
5791 receiver can decrypt the packet with several keys and check from
5792 the MAC which key decrypted the message correctly.
5794 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5795 lib/silccrypt/silccipher.[ch].
5797 * Added silc_hash_len to return the digest length into the
5798 lib/silcrypt/silchash.[ch].
5800 * Rewrote parts of Silc Channel Payload interface in the
5801 lib/silccore/silcchannel.[ch]. The encode function now also
5802 encrypts the packet and parse function decrypts it.
5804 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Fixed a minor formatting bug in the SKE's key material processing.
5807 It actually might have processed the keys wrong way resulting
5810 * Redefined the mandatory HMAC algorithms and added new algorithms.
5811 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5812 and hmac-md5 truncated to 96 bits. The mandatory is now
5813 hmac-sha1-96. Rest are optional (including the one that used
5814 to be mandatory). Rationale for this is that the truncated HMAC
5815 length is sufficient from security point of view and can actually
5816 make the attack against the HMAC harder. Also, the truncated
5817 HMAC causes less overhead to the packets. See the RFC2104 for
5820 * Added new [hmac] configuration section. The SKE used to use
5821 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5822 is of course wrong. The official names that must be proposed in
5823 the SKE are the ones defined in the protocol specification
5824 (hmac-sha1-96 for example). The user can configure any hmac
5825 using any hash function configured in the [hash] section. At
5826 least, the mandatory must be configured.
5828 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5830 * Added HMAC list to the SKE proposal list. It has now both
5831 hash algorithm list and HMAC list. This makes the protocol
5832 incompatible with previous versions. The SKE now seems to work
5833 the way it is supposed to work, for the first time actually.
5835 * Defined plain Hash algorithms to the protocol specification.
5838 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Implemented support for key agreement packets into the server.
5841 Added functions silc_server_key_agreement and
5842 silc_server_send_key_agreement. Other than these functions,
5843 server has nothing to do with this packet.
5845 * Added support for private message key packets into the server.
5846 Added functions silc_server_private_message_key and
5847 silc_server_send_private_message_key.
5851 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5852 called in the protocol's final callback instead in the END
5853 protocol state. This makes a little more sense and in the same
5854 time in client we can use the same protocol routines for normal
5855 key exchange and to key agreement packet handling as well.
5857 * Added to both client's and server's KE protocol context the
5858 SilcSKEKeyMaterial pointer to save the key material. We will
5859 bring the key material to the protocol's final callback by doing
5860 this. The final callback must free the key material.
5862 * Added SKE's packet_send callback into client's KE protocol
5863 context so that the caller can choose what packet sending function
5864 is used. This way we can use different packet sending when
5865 doing normal SKE when doing key agreement packet handling (in
5866 the key agreement packet handling we do not want to encrypt
5869 * Implemented the responder side of the key agreement routines
5870 in the client. The client can now bind to specified port and
5871 accept incoming key negotiation. The key material is passed
5872 to the application after the protocol is over.
5874 * Implemented the processing of incoming Key Agreement packet
5875 in the client. Added function silc_client_key_agreement to
5878 * Implemented the intiator side of the key agreement routines
5879 in the client. The client can now initiate key agreement with
5880 another remote client. The key material is passed to the
5881 application after the protocol is over.
5883 * Created client_keyagr.c to include all the key agreement
5886 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5887 SILC_TASK_CALLBACK except that it is not static.
5889 * Created client_notify.c and moved the Notify packet handling
5890 from the client.[ch] into that file.
5892 * Created client_prvmsg.c and moved all private message and
5893 private message key routines from the client.[ch] into that file.
5895 * Create client_channel.c and moved all channel message and
5896 channel private key routines from the client.[ch] into that file.
5898 * Changed silc_client_get_client_by_id_resolve to resolve with
5899 WHOIS command instead of IDENTIFY command, in the file
5900 lib/silclient/idlist.c.
5902 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Implemented the SKE's responder side to the Client library.
5906 * When FAILURE is received to the protocol do not trust it
5907 blindly. Register a timeout to wait whether the remote closes
5908 the connection as it should do it, only after that process the
5909 actual failure. This was changed to both client and server.
5911 * Added client_internal.h to include some of the structures
5912 there instead of client.h in lib/silcclient/.
5914 * Added function silc_task_unregister_by_callback to unregister
5915 timeouts by the callback function.
5917 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Some "Incomplete WHOIS info" errors has been appearing on the
5920 log files. Took away the entry->userinfo check from WHOIS
5921 reply sending. The entry->userinfo is now " " if client did not
5922 provide one. I thought this was fixed earlier but something
5923 is wrong still. Let's see if the error still appears.
5925 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Fixed a minor bug in the login when the channel key is
5928 re-generated in the server. It used to generate the key in
5929 wrong order and thus caused problems in the channel traffic.
5931 * Fixed a minor bug in channel key distsribution after
5932 KICK command. The key was not sent to the router even though
5935 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Added silc_ske_process_key_material_data as generic routine
5938 to process any key material as the SILC protocol dictates. The
5939 function is used by the actual SKE library but can be used by
5940 applications as well. This relates to the private message keys
5941 and the channel private keys since they must be processed the
5942 same way the normal SILC session keys. The protocol dictates
5943 this. Affected files: lib/silcske/silcske.[ch].
5945 Added also silc_ske_free_key_material to free the
5946 SilcSKEKeyMaterial structure.
5948 * Defined silc_cipher_set_key function to set the key for
5949 cipher without using the object's method function. The affected
5950 files: lib/silccrypt/silccipher.[ch].
5952 * Implemented silc silc_client_add_private_message_key,
5953 silc_client_add_private_message_key_ske,
5954 silc_client_del_private_message_key,
5955 silc_client_list_private_message_keys and
5956 silc_client_free_private_message_keys functions in the
5959 Added functions silc_client_send_private_message_key to send
5960 the Private Message Key payload and silc_client_private_message_key
5961 to handle incoming Private Message Key payload.
5963 * Added Cipher field to the Private Message Key payload to set
5964 the cipher to be used. If ignored, the default cipher defined
5965 in the SILC protocol (aes-256-cbc) is used.
5967 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Removed lib/silcclient/ops.h file.
5971 Redefined parts of the SILC Client Library API. Created new
5972 file silcapi.h that deprecates the ops.h file and defines the
5973 published Client Library API. Defined also private message key
5974 API and channel private key API into the file.
5976 This is the file that the application must include from the
5977 SILC Client Library. Other files need not be included by
5978 the application anymore.
5980 * Added new key_agreement client operation callback and also
5981 defined the Key Agreement library API for the application.
5983 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5986 is used by clients to request key negotiation between another
5987 client in the SILC network. If the negotiation is started it
5988 is performed using the SKE protocol. The result of the
5989 negotiation, the secret key material, can be used for example
5990 as private message key.
5992 Implemented the Key Agreement payload into the files
5993 lib/silccore/silauth.[ch].
5995 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Redefined ciphers for the SILC protocol. Added some new ciphers
5998 and defined the key lengths for the algorithms. Changed the
5999 code accordingly. The default key length is now 256 bits.
6001 * Fixed SKE key distribution function silc_ske_process_key_material
6002 when the key length is more than 128 bits. The default key
6003 length in SILC is now 256 bits.
6005 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6006 to indicate unsupported algorithm.
6008 * Renamed rijndael.c to aes.c and all functions as well.
6010 * Fixed a long standing channel key setting bug in client library.
6011 Weird that it has never surfaced before.
6013 * Fixed bug in channel deletion. If the entire channel is removed
6014 then it must also delete the references of the channel entry
6015 from the client's channel list as the client's channel entry and
6016 the channel's client entry share same memory.
6018 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Implemented CONNECT and SHUTDOWN commands in the client.
6022 * Implemented CLOSE command to the client.
6024 * Added the function silc_idlist_find_server_by_name into the
6025 files silcd/idlist.[ch].
6027 Added the function silc_idlist_find_server_by_conn into the
6028 files silcd/idlist.[ch].
6030 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * DIE command was renamed to SHUTDOWN. Updated the both code
6035 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6036 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6038 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6041 * Added function silc_server_create_connection function to create
6042 connection to remote router. My server implementation actually
6043 does not allow router to connect to normal server (it expects
6044 that normal server always initiates the connection to the router)
6045 so the CONNECT command is only good for connecting to another
6048 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6051 or some other client was kicked from the channel.
6053 Implemented the handling of the notify type to both client
6056 Implemented silc_server_send_notify_kicked to send the KICKED
6057 notify. It is used to send it to the server's primary router.
6059 * Implemented the KICK command into server and client.
6061 * Added `query' argument to the silc_idlist_get_client function
6062 to indicate whether to query the client from server or not if
6065 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6066 to indicate that the client is not channel founder.
6070 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6072 * Removed the rng context from SilcPacketContext structure and
6073 changed that the packet routine uses the Global RNG API.
6075 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Added support for quit message that client can "leave" on the
6078 channel when it quits the SILC. It is ditributed inside the
6079 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6081 Added silc_server_free_client_data that will take the
6082 signoff message as argument.
6084 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6086 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Updated parts of the protocol specification to keep it up
6091 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6094 payloads in one packet.
6096 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6097 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6098 use now the new List flag.
6100 * Also deprecated the following packet types: REPLACE_ID,
6101 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6103 * Added list support for Notify packet in server.
6105 * Added silc_server_send_notify_channel_change to send the
6106 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6107 the silc_server_send_replace_id.
6109 * Added silc_server_send_notify_nick_change to send the
6110 NICK_CHANGE notify type. Deprecates the function
6111 silc_server_send_replace_id.
6113 * Added silc_server_send_notify_join to send the JOIN notify type.
6114 Deprecates the function silc_server_send_new_channel_user.
6116 * Added silc_server_send_notify_leave to send LEAVE notify type.
6117 Deprecates the function silc_server_send_remove_channel_user.
6119 * Added silc_server_send_notify_cmode and
6120 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6121 types. Deprecates the silc_server_send_set_mode function.
6123 * Added SERVER_SIGNOFF notify type to indicate that server has
6124 quit. This means that all clients on the channel from that
6125 server will drop. This can be also used when netsplit happens.
6127 Deprecated REMOVE_ID packet type since it is not needed anymore
6130 Added silc_server_send_notify_server_signoff to send the
6131 SERVER_SIGNOFF notify type. Deprecates the function
6132 silc_server_send_remove_id.
6134 Added also silc_server_send_notify_signoff to send the
6135 SIGNOFF notify type.
6137 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6138 SILC protocol from this day on. Changed the protocol
6139 specification as well.
6141 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6142 notify type. It is used between routers to notify about
6143 topic changes on a channel.
6145 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6148 * Partly updated the protocol specification to comply with the
6149 changes now made. It is still though a bit outdated.
6151 * The JOIN notify type now takes one extra argument <Channel ID>.
6152 The packet used to be destined to the channel but now the
6153 JOIN type may be sent as list thus it is impossible to
6154 destine it to any specific channel. By adding this argument
6155 it is again possible.
6157 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Added CREDITS file. The CHANGES and CREDITS file will appear
6160 in the distribution as well.
6162 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6165 types in the server's silcd/packet_receive.c.
6167 * Implemented CMODE and CUMODE to work in router environment.
6169 * Fixed minor encoding and decoding buglet from the
6170 lib/silccore/silcmode.c.
6172 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6175 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6177 * Changed all SilcConfigServer* and silc_config_server* to
6178 SilcServerConfig* and silc_server_config*, respectively.
6181 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Associated the ID (client or server ID) to the Authentication
6184 Payload to avoid any possibility of forging. Updated the
6185 protocol specification and the code accordingly.
6187 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * The RSA key length is now save to the RsaKey context in the
6190 key generation process in lib/silccrypt/rsa.c. The key length
6191 is now used to figure out the maximum size of the block allowed
6192 to be encrypted/signed.
6194 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6195 is equivalent to the silc_mp_mp2bin but does not allocate any
6198 * Changed silc_mp_mp2bin API to take length argument. If it is
6199 non-zero then the buffer is allocated that large. If zero, then
6200 the size is approximated using silc_mp_sizeinbase, which however
6203 * Created Global RNG API which is global RNG that application can
6204 initialize. After initializing, any routine anywhere in the
6205 code (including library) can use RNG without allocating a new
6206 RNG object. This was done to allow this sort of use of the
6207 RNG in code that has no chance to allocate RNG object. All
6208 applications currently allocate this and many routines in the
6209 library use this. Affected file lib/silccrypt/silcrng.[ch].
6211 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6212 it to use the Global RNG API.
6214 * Defined Authentication Payload into protocol specification that
6215 is used during SILC session to authenticate entities. It is
6216 used for example by client to authenticate itself to the server
6217 to obtain server operator privileges.
6219 Implemented this payload into the lib/silccore/silcauth.[ch].
6220 Implemented also routines for public key based authentication
6221 as the new protocol specification dictates.
6223 Moved definitions of different authentication methods from
6224 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6226 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6227 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6228 silc_pkcs_verify_with_hash functions into the file
6229 lib/silccrypt/silcpkcs.[ch].
6231 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * The client entry's userinfo pointer must be always valid.
6234 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6235 will fail since it requires the userinfo. Now, the userinfo
6236 is allocated as "" if actual userinfo does not exist. Actually,
6237 it must exist and it is totally Ok to drop client connections
6238 that does not announce the userinfo. However, we will make
6239 this workaround for now.
6241 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6242 to return the remote port by socket.
6244 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6247 SILC_SERVER_PENDING_EXEC and added an new macro
6248 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6249 data or when error occurs while processing the pending command.
6251 Added new argument `destructor' into silc_server_command_pending
6252 and to the SilcServerCommandPending object. This destructor is
6253 now called after calling the pending callback or if error occurs
6254 immediately. If error occurs the actual pending callback won't
6255 be called at all - only the destructor. The destructor may be
6256 NULL if destructor is not needed.
6258 All this applies for client library code as well. Similar
6259 changes were made there as well for the pending commands.
6261 In the client, the application must now allocate the
6262 SilcClientCommandContext with the silc_client_command_alloc
6265 * Added reference counter to the SilcServerCommandContext. Added
6266 function silc_server_command_alloc and silc_server_command_dup
6269 Same type of functions added to the client library for the same
6272 * Removed the cmd_ident from IDListData away since it is now
6273 global for all connections. It is the command identifier used
6274 in command sending and with pending commands. The affected file
6277 * Added reference counter to the SilcSocketConnection objecet to
6278 indicate the usage count of the object. The object won't be
6279 freed untill the reference counter hits zero. Currently only
6280 server uses this, and client ignores it. The client must be
6281 set to use this too later. The affected files are
6282 lib/silccore/silcsockconn.[ch]. Added also the function
6283 silc_socket_dup to increase the reference counter.
6285 This was mainly added because it is possible that the socket
6286 is removed underneath of pending command or other async
6287 operation. Now it won't be free'd and proper DISCONNECTING
6288 flags, etc. can be set to avoid sending data to connection that
6289 is not valid anymore.
6291 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6292 the connection. After that it sets SILC_SET_DISCONNECTED.
6293 It is, however, possible that the socket data is not still freed.
6294 The silc_server_packet_process now checks that data is not
6295 read or written to connection that is DISCONNECTED. The socket
6296 get's freed when the reference counter hits zero.
6298 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Changed the client operation API: channel_message operation's
6301 `sender' is now the client entry of the sender, not the nickname
6302 and the `channel' is the channel entry, not the channel name.
6304 In the private_message operation the `sender' is now also the
6305 client entry of the sender not the nickname.
6307 Affected file is lib/silcclient/ops.h and all applications
6308 using the client operations.
6310 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Moved the calling of ops->connect() from connect_to_server_final
6313 into receive_new_id functin since that is the point when the
6314 client is actually allowed to send traffic to network. The
6315 affected file is lib/silcclient/client.c.
6317 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6320 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6321 (if needs broadcasting) instead of broadcasting the packets one
6322 by one which would make a burst in the network traffic.
6324 * Added `broadcast' argument to the functions in silcd/server.[ch]
6325 silc_server_create_new_channel[_with_id] to indicate whether
6326 to send New Channel packet to primary router.
6328 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Added new function into the silcd/server.[ch] files:
6331 silc_server_create_new_channel_with_id to create new channel with
6332 already existing Channel ID.
6334 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6335 lib/silccore/silcpacket.h. This packet is used t send list of
6336 Set Mode payloads inside one packet. Server uses this to set
6337 the modes for the channels and clients on those channels, that it
6338 announced to the router when it connected to it. The protocol
6339 specification has been updated accordingly.
6341 * The silc_server_new_channel did not handle the packet coming
6342 from normal server as it normally does not send that. However,
6343 when it announces its channels it does send it. Implemented
6344 the support for that.
6346 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6347 into the file lib/silccore/id.h.
6349 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Fixed memory leaks in the functions silc_idlist_del_client,
6352 silc_idlist_del_channel and silc_idlist_del_server in the file
6353 silcd/idlist.c. All of those leaked like a sieve.
6355 * Fixed some small memory leaks in the client's function
6356 silc_client_notify_by_server.
6358 * Added functions into silcd/server.c: silc_server_announce_clients,
6359 silc_server_announce_channels and silc_server_announce_server.
6360 These functions are used by normal and router server to announce
6361 to its primary router about clients, channels and servers (when
6362 router) that we own. This is done after we've connected to the
6365 These functions effectively implements the following packet types:
6366 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6367 and SILC_PACKET_NEW_ID_LIST.
6369 * Added new functions into the silcd/packet_receive.[ch]:
6370 silc_server_new_id_list, silc_server_new_channel_list and
6371 silc_server_new_channel_user_list to handle the incoming
6372 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6374 * Added support of changing Channel ID in the function
6375 silc_server_replace_id. If the server that announces a channel
6376 to the router already exists in the router (with same name but
6377 with different Channel ID), router is responsible to send
6378 Replace ID packet to the server and force the server to change
6379 the Channel ID to the one router has.
6381 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6382 client that the Channel ID has been changed by the router. The
6383 normal server sends this to the client. Client must start using
6384 the new Channel ID as the channel's ID.
6386 Implemented handling of this new type into lib/silcclient/client.c
6387 into the function silc_client_notify_by_server.
6389 * Added new function silc_idlist_replace_channel_id into the files
6390 silcd/idlist.[ch] to replace the Channel ID.
6392 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Call silc_server_command_identify_check always when processing
6395 the IDENTIFY command in silcd/command.c
6397 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6400 send keepalive packets. The packet can be sent by clients,
6401 servers and routers.
6403 Added function silc_socket_set_heartbeat into the file
6404 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6405 If not set, the heartbeat is not performed. The actual
6406 heartbeat is implemented in the low level socket connection
6407 library. However, application is responsible of actually
6410 Added silc_server_send_heartbeat to send the actual heartbeat
6411 packet into silcd/packet_send.[ch]. Server now performs
6412 keepalive with all connections.
6414 * Added silc_task_get_first function into lib/silcutil/silctask.c
6415 to return the timeout task with shortest timeout. There was a bug
6416 in task unregistration that caused problems. TODO has been
6417 updated to include that task system must be rewritten.
6419 * The client library will now resolve the client information when
6420 receiving JOIN notify from server for client that we know but
6421 have incomplete information.
6423 * Rewrote parts of silc_server_remove_from_channels and
6424 silc_server_remove_from_one_channel as they did not remove the
6425 channel in some circumstances even though they should've.
6427 * Encryption problem encountered in server:
6429 The LEAVE command used to send the Channel Key packet to the
6430 router immediately after generating it. However, the code
6431 had earlier sent Remove Channel user packet but not immediately,
6432 ie. it was put to queue. The order of packets in the router
6433 was that Channel Key packet was first and Remove Channel User
6434 packet was second, even though they were encrypted in the
6435 reverse order. For this reason, MAC check failed. Now, this
6436 is fixed by not sending the Channel Key packet immediately but
6437 putting it to queue. However, this is more fundamental problem:
6438 packets that are in queue should actually not be encrypted
6439 because packets that are sent immediately gets encrypted
6440 actually with wrong IV (and thus MAC check fails). So, packets
6441 that are in queue should be encrypted when they are sent to
6442 the wire and not when they put to the queue.
6444 However, the problem is that the current system has not been
6445 designed to work that way. Instead, the packet is encrypted
6446 as soon as possible and left to the queue. The queue is then
6447 just purged into wire. There won't be any fixes for this
6448 any time soon. So, the current semantic for packet sending
6451 o If you send packet to remote host and do not force the send
6452 (the packet will be in queue) then all subsequent packets to the
6453 same remote host must also be put to the queue. Only after the
6454 queue has been purged is it safe again to force the packet
6457 o If you send all packets immediately then it safe to send
6458 any of subsequent packets through the queue, however, after
6459 the first packet is put to queue then any subsequent packets
6460 must also be put to the queue.
6462 Follow these rules and everything works fine.
6464 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Added new function silc_server_remove_clients_by_server to
6467 remove all client entries from ID list when the server connection
6468 is lost. In this case it is also important to invalidate all
6469 client entires as they hold the invalid server entry. This
6470 fixes fatal bug when server has lost connection and will reconnect
6473 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Made some sanity checks to silc_server_daemonise like to check
6476 whether the requested user and group actually exists.
6478 * Added sanity check to SKE's silc_ske_responder_finish to check
6479 that the public and private key actually is valid.
6481 * Invalidate the client's nickname when receiving Replace ID
6482 packet and the Client ID is being replaced. This means that the
6483 server will query the nickname if someone needs it (client)
6486 * Sort the ID Cache in client library when the ID Cache data
6487 has changed (needs sorting).
6489 * Do not allow for SILC client to create several connections to
6490 several servers. The client does not support windows right now
6491 and generating multiple connections causes weird behaviour.
6493 Irssi-silc client does support windows and can handle several
6494 connections without problems, see: www.irssi.org and SILC plugin.
6496 * Fixed some places where client was added to the IDList. The
6497 rule of thumb is following (in order to get everything right):
6498 If the client is directly connected local client then the
6499 `connection' argument must be set and `router' argument must be
6500 NULL to silc_idlist_add_client function. If the client is not
6501 directly connected client then the `router' argument must
6502 bet set and the `connection' argument must be NULL to the
6503 silc_idlist_add_client function.
6505 * The funtion silc_server_packet_send_local_channel actually did
6506 not check whether the client was locally connected or not. It
6507 does that now. Fixed a bug related to LEAVE command.
6509 * Fixed Remove Channel User payload parsing bug in server's
6510 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6512 * The server's silc_server_save_channel_key now checks also the
6513 global ID list for the channel as it might not be in the local
6514 list. Fixed a bug related to LEAVE command.
6516 * Is this the end of the [<unknown>] buglet that has been lurking
6517 around for a long time? A little for loop fix in server's
6518 silc_server_command_whois_parse that is used by both IDENTIFY
6519 and WHOIS command. At least, this was a clear bug and a cause
6520 of one type of [<unknown>] buglet.
6522 * WHOIS and IDENTIFY commands call the function
6523 silc_server_command_[whois/identify]_check function even if
6524 we are not router server.
6526 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Added --with-gmp configuration option. If set the GMP
6529 is always compiled in the SILC source tree. If not set then
6530 it is checked whether the system has the GMP3 installed. If
6531 it has then the GMP won't be compiled (the system's headers
6532 and library is used), if it doesn't have it then the GMP is
6533 compiled in the SILC source tree.
6535 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Changed RSA private exponent generation to what PKCS #1
6538 suggests. We try to find the smallest possible d by doing
6539 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6540 not security fix but optimization.
6542 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Added new config entry [Identity] to fork the server and run
6545 it as specific user and group. A patch from Bostik.
6547 * Imported Dotconf configuration library into lib/dotconf.
6548 This will be used to create the SILC configuration files later.
6549 It will appear in the distsribution after this commit.
6551 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * A big code auditing weekend happening. Auditing code for
6554 obvious mistakes, bugs and errors. Also, removing any code
6557 Removed files for being obsolete:
6559 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6560 inline in the file lib/silcutil/silcbuffer.h)
6562 o lib/silcutil/silcbufutil.c (the header has inline versions)
6564 Changed code to fix possible error conditions:
6566 o The buffer formatting routines now check that the destination
6567 buffer really has enough space to add the data. This applies for
6568 both buffer formatting and unformatting
6569 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6570 unformatting was changed to accomodate following rules:
6571 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6572 sent to the function while XXX_*STRING will not allocate or copy
6573 the data into the buffer. Instead it sets the pointer from the
6574 buffer into the pointer sent as argument (XXX_*STRING used to
6575 require that the pointer must be allocated already). This change
6576 makes this whole thing a bit more consistent and more optimized
6577 (note that the data returned in the unformatting with XXX_*STRING
6578 must not be freed now). The routines return now -1 on error.
6580 o Tried to find all code that use buffer_format and buffer_unformat
6581 and added return value checking to prevent formatting and
6582 especially unformatting errors and possible subsequent fatal
6585 o Changed ske->x and ske->KEY to mallocated pointers in
6586 lib/silcske/silcske.h. Fixed possible data and memory leak.
6588 o Added return value checking to all *_parse* functions. Fixed
6589 many memory leaks as well.
6591 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6592 so that buffer overflows would not happen. All code now also
6593 checks the return value as it can fail.
6595 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Added reconnection support to server if the normal server looses
6598 its connection to the router (for example if router is rebooted).
6599 The server performs normal reconnection strategy implemented
6600 to the server. Affected file silcd/server.c.
6602 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Added new packet type SILC_PACKET_SET_MODE that is used to
6605 distribute the information about changed modes (for clients,
6606 channels and clients channel modes) to all routers in the
6607 network. Updated the protocol specification accordingly.
6609 Added functions into silcd/packet_send.c and
6610 silcd/packet_receive.c: silc_server_send_set_mode,
6611 silc_server_set_mode.
6613 Added new files silcmode.[ch] into lib/silccore that implements
6614 the encoding and decoding of Set Mode Payload. Added new type
6615 SilcSetModePayload. Moved the definitions of different modes
6616 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6618 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Oops, a little mistake in server's connection authentication
6621 protocol. The protocol is not ended with FAILURE but with
6622 SUCCESS if the authentication is Ok. :) Affected file is
6625 * Implemented NICK_CHANGE notify handling in server in the file
6626 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6627 the local clients on the channel. After the changing nickname
6628 in router environment snhould work and the [<unknown>] nickname
6629 should appear no more.
6631 The silc_server_replace_id function that receives the Replace ID
6632 payload now sends the NICK_CHANGE notify type also in the file
6633 silcd/packet_receive.c
6635 * Changed WHOIS and IDENTIFY command to support the maximum amount
6636 of arguments defined in protocol specs (3328 arguments). This
6637 fixed a bug that caused problems when there were more than three
6640 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Added extra parameter, command identifier, to the
6643 silc_client_send_command so that explicit command identifier
6646 Changed that ID list routines uses specific command identifier
6647 when sending WHOIS/IDENTIFY requests to the server so that they
6648 can be identified when the reply comes back.
6650 Affected files lib/silcclient/command.[ch],
6651 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6653 * Added `sender' argument to silc_server_packet_send_to_channel
6654 to indicaet the sender who originally sent the packet to us
6655 that we are now re-sending. Ignored if NULL. Affected file
6656 silcd/packet_send.[ch].
6658 * Added some server statistics support in silcd/server_internal.h
6659 SilcServerStatistics structure and around the server code. Also
6660 send some nice statistics information when client is connecting
6663 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Fixed channel ID decoding in server's JOIN command reply in
6666 silcd/command_reply.c
6668 * Fixed braodcasting of replace ID payload to not to send it if
6669 we are standalone server in silcd/packet_receive.c.
6671 * Fixed all channel message sending routines to not to send
6672 packets to clients that has router set, since they are routed
6673 separately in the same function earlier. Affects file
6674 silcd/packet_send.c and all channel packet sending functions.
6676 * In USERS reply, res_argv[i] are not allocated, the table
6677 is allocated. Thus changed that free the table, not its
6680 * In server's whois_check and identify_check if the client is
6681 locally connected do not send any WHOIS commands - they are not
6684 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Fixed some minor bugs in client when sending WHOIS command. The
6687 arguments was in wrong order.
6689 * Removed statis function add_to_channel from server in
6690 silcd/command.c that was previously used with the joining but
6693 * Tested USERS command in router environment successfully with two
6694 routers, two servers and two clients.
6696 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6698 * Reorganized the USERS command and command reply in client library
6699 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6700 When the command is given by user we register a pending command
6701 callback that will reprocess the command after the reply has been
6702 received from the server. When reprocessing the packet we then
6703 display the information. Thus, the USERS information is displayed
6704 now in the command callback instead of in the command reply
6705 callback. The processing of the command is same as previously
6706 when server has sent the command reply in the JOINing process.
6708 * Added to USERS command in silcd/command_reply.c to join the client,
6709 we didn't use to know about, to the channel after we've created
6710 a client entry for it. Also, for clienet we did know already still
6711 check whether it is on the channel or not and add it if not.
6713 * Removed silc_server_command_join_notify as the function and its
6716 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Changed the client's pending command handling to the same as the
6719 server's pending command handling. It is also now possible to
6720 execute command reply functions from other command reply
6721 function as the function callbacks for commands and command
6722 replies are one and same. The pending commands are not static
6723 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6724 in client connection context. Thus, pending commands are server
6725 connection specific as it is convenient.
6727 Changed the function silc_client_command_pending and
6728 silc_client_command_pending_del and added new function
6729 silc_client_command_pending_check. Removed the
6730 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6733 * Added cmd_ident, current command identifier, to the client
6734 connection context in lib/silcclient/client.h to keep track on
6735 command identifiers used in command sending. Client's command reply
6736 function handling now supports the mandatory command identifiers.
6738 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6739 funtions in client to fully support pending command callbacks.
6741 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6742 as one of the arguments to the application in the command reply
6745 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6746 before first releasing SILC but came back. Now it is removed again
6747 and should come back nomore. The FORWARDED flag was used only
6748 by the JOINing procedure by forwarding the command packet to router.
6749 Now, the JOINing procedure has been changed to more generic (due
6750 to various router environment issues) and FORWARDED is not needed
6751 anymore for anything. The protocol specification is yet to be
6754 Now, removed silc_server_packet_forward from server and the flag
6755 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6757 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Renamed NAMES command to USERS command. The NAMES was named that
6760 due to historical reasons. Now it is renamed. Also, rewrote
6761 parts of the USERS command. The nickname list is not sent anymore
6762 by the server. Only Client ID and mode lists are sent in the USERS
6763 command. Changed this also to the protocol specification.
6765 The client now resolves the names and stuff after it receives
6766 the USERS list from the server when joining to the channel.
6768 * WHOIS and IDENTIFY commands has been changed to support multiple
6769 Client ID's per command. One can now search for multiple users
6770 in the network by sending only one WHOIS or IDENTIFY command.
6771 Changed the code and the protocol specifications.
6773 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6774 uses silc_server_command_whois_parse to parse the request. */
6776 * If normal server, do not parse the WHOIS and IDENTIFY requests
6777 before sending it to the router. Saves some time.
6779 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Fixed JOIN command on client library. Wrong number of arguments
6782 used to crash the client.
6784 * Added silc_server_channel_has_global function to check whether
6785 channel has global users or not.
6787 * Added silc_server_channel_has_local function to check whether channel
6788 has locally connected clients on the channel.
6790 * The silc_server_remove_from_one_channel now checks whether the
6791 channel has global users or not after given client was removed from
6792 the channel. It also checks whether the channel has local clients
6793 on the channel anymore. If it does not have then the channel entry
6794 is removed as it is not needed anymore.
6796 * The silc_server_notify now checks on JOIN notify whether the joining
6797 client is one of locally connected or global. If it is global then
6798 the channel has now global users on the channel and that is marked
6799 to the channel entry. Also, it now saves the global client to
6800 global list who is joining and JOINs it to the channel. This is
6801 for normal server, that is.
6803 Changed silc_server_send_notify_on_channel,
6804 silc_server_packet_relay_to_channel and
6805 silc_server_packet_send_to_channel check if we are normal server
6806 and client has router set (ie. global client) do not send the
6807 message to that client, as it is already routed to our router.
6809 * Implemented LEAVE notify type handling in silc_server_notify
6812 * Tested LEAVE command in router environment successfully. Tested
6813 with two routers, two servers and two clients.
6817 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6819 * Implemented SIGNOFF notify type handling in silc_server_notify
6822 * silc_server_remove_id now removes the client entry from all channels
6823 it has joined and thusly sends SIGNOFF notify type.
6825 * Rewrote the NAMES list generation in server by removing two excess
6826 loops. The lists are created now inside one loop.
6828 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * silc_server_remove_channel_user checks now also global list
6831 for channel and client.
6833 * silc_server_new_channel_user checks now both local and global
6834 list for channel and client. Fixed a bug in client id decoding.
6835 Used to decode wrong buffer.
6837 * silc_server_channel_message checks now both local and global
6838 list for channel entry.
6840 * Tested channel joining (hence JOIN) in router environment
6841 successfully. Tested with two routers, two servers and two
6844 * Tested channel message sending in router environment successfully.
6846 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Added silc_server_save_channel_key into server.[ch] to save the
6849 received channel key in Channel Key payload processing. It is
6850 also used in JOIN command reply handling.
6852 Equivalent function silc_client_save_channel_key added into
6853 client.[ch] into client library.
6855 * Changed JOIN command reply to send information whether the channel
6856 was created or not (is existing already) and the channel key
6857 payload. Changed protocol specs accordingly.
6859 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6860 the request was sent by ID and not by nickname. Crashed on
6863 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6866 now correctly save the received data.
6868 * silc_server_free_sock_user_data now notifies routers in the
6869 network about entities leaving the network.
6871 At the same time implemented functions silc_server_remove_id
6872 and silc_server_send_remove_id to receive and send REMOVE_ID
6873 packets. The packet is used to notify routers in the network
6874 about leaving entities. The ID removed will become invalid in
6877 * Added function silc_idlist_del_server into server. Removes and
6878 free's server entry from ID list.
6880 * silc_server_private_message function now checks, if we are router,
6881 that the destination ID really is valid ID, naturally.
6883 * In router when NEW_ID packet is received (for new client) the
6884 hash of the Client ID is saved in the ID Cache but the
6885 client->nickname is set to NULL, instead of putting the hash
6888 IDENTIFY command now also checks that client->nickname must be
6889 valid. If it is not if will request the data from the server who
6890 owns the client. Added new function
6891 silc_server_command_identify_check.
6893 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6894 to set the command to already allocated Command Payload.
6896 * Tested private message sending in router environment with two
6897 routers, two servers and two clients. Fixed minor bugs and now
6900 * Fixed segfault from client's NAMES command. Used to crash if
6903 * Forwarded packets must not be routed even if it is not destined
6904 to the receiver. Changed server code comply with this.
6906 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Added `require_reverse_mapping' boolean value to ServerParams
6909 structure. If TRUE (not default) the server will require that
6910 the connecting host has fully qualified domain name.
6912 If the reverse mapping is not required and hostname could not be
6913 found the IP address is used as hostname.
6915 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6917 * Implemented version string checking to both client and server.
6918 The check is incomplete currently due to the abnormal version
6919 strings used in development version of SILC.
6921 * Changed all command functions in server to use the new
6924 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Changed char *data to unsigned char *data in ID Cache system to
6927 support binary data as ID Cache data. Changed code to support
6928 binary data in lib/silccore/idcache.c.
6930 * Renamed silc_server_packet_relay_command_reply to
6931 silc_server_command_reply as it is normal packet receiving
6932 function. Rewrote the function to accept command replys for
6933 servers and not only for clients.
6935 * Mark remote router always as registered server if we are connecting
6936 to it. Otherwise, commands sent by the router to us are ignored.
6938 * All ID List find routines now returns the ID Cache Entry pointer
6939 as well if requested.
6941 * WHOIS command works now in router environment, tested with two
6942 routers, two servers and two clients.
6944 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6945 in router environment (as it is almost equivalent to WHOIS) but
6946 hasn't been tested thoroughly. Added new functions:
6948 silc_server_command_identify_parse
6949 silc_server_command_identify_send_reply
6950 silc_server_command_identify_from_client
6951 silc_server_command_identify_from_server
6953 * Disabled route cache adding because adding two different ID's with
6954 same IP replaces the old cache entry thus giving wrong route.
6955 The entry->router->connection is always the fastest route anyway
6956 so route cache may not be needed. Of course, new routes maybe
6957 established after receiving the ID when the entry->router->connection
6958 might not be anymore the most optimal.
6960 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Add route cache for received ID for fast routing.
6964 * Added silc_server_packet_route to route received packet on router
6965 that is not destined to us.
6967 * Renamed silc_server_get_route to silc_server_route_get.
6969 * Added id_string and id_string_len fields into SilcServer to
6970 include encoded ServerID for fast comparing without excess
6971 encoding of the ID's.
6973 * Cleaned up WHOIS command on server side. Added following static
6976 silc_server_command_whois_parse
6977 silc_server_command_whois_check
6978 silc_server_command_whois_send_reply
6979 silc_server_command_whois_from_client
6980 silc_server_command_whois_from_server
6982 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6983 arguments in command replies. All command functions should be
6984 updated to use this macro.
6986 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Minor typo fixes on command reply handling on server.
6990 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Added silc_server_command_add_to_channel internal routine to add
6993 the client to the channel after router has created the channel and
6994 sent command reply to the server.
6996 * Added generic silc_server_send_command to send any command from
6999 * Use static buffer with ID rendering instead of duplicating data.
7001 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Fixed a channel user mode bug when joining to a channel server gave
7004 everybody channel founder rights, oops.
7006 * We mark ourselves as the router of the incoming server connection
7007 if we are router ourselves. This way we can check in some packet
7008 sending functions whether it is locally connected server. For
7009 incoming router connections we put NULL.
7011 * For router sending packets locally means now always sending the
7012 packet cell wide; to local clients and local servers. For normal
7013 server sending packet locally means sending it to only local
7016 * Fixed the JOIN command to really work in router environment. If the
7017 channel is created it is always created by the router. Router is
7018 also responsible of making the initial joining to the channel,
7019 sending JOIN notify to the sending server and distributing
7020 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7021 does not exist server doesn't do anything else but forward the
7022 command to the router which performs everything.
7024 * Added silc_server_send_channel_key function to send the Channel Key
7027 * Added silc_server_create_channel_key to create new channel key. The
7028 channel key is now re-generated everytime someone joins or leaves
7029 a channel, as protocol dictates. Note: channel->key_len is the
7032 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7035 packet_receive.[ch] to separate packet sending and receiving
7036 routines. The server.[ch] now includes everything else including
7037 actual packet processing (writing and reading data) and other
7040 Renamed silc_server_private_message_send_internal to
7041 silc_server_send_private_message. The routine is still though
7042 used only to relay private messages as server does not send
7043 private messages itself.
7045 Renamed silc_server_new_channel to silc_server_create_new_channel
7046 and added new function sicl_server_new_channel that handles the
7047 incoming New Channel packet. Added also new sending function
7048 silc_server_send_new_channel to send New Channel Payload.
7050 * Added new function silc_server_notify to process incoming notify
7051 packet to the server/router. Server may then relay the notify
7052 to clients if needed.
7054 * Added new function silc_server_new_channel_user to process incoming
7055 New Channel User packet. Router will redistribute the packet and
7056 send JOIN notify to its local clients and locally connected servers
7057 if needed. Normal server will send JOIN notify to its local client
7058 on same channel when received this packet. Added also corresponding
7059 sending function silc_server_send_new_channel_user to sent the
7062 * Added boolean route argument to send_notif_to_channel and
7063 packet_send_to_channel functions to attempt to route the packet
7064 if it is TRUE and send only locally if it is FALSE.
7066 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * silc_server_replace_id now broadcasts the received replace ID
7069 packet if it is not broadcast packet already. The router must
7070 broadcast to inform other routers about changed ID.
7072 * Added backpointer to server's router into SilcServer context in
7073 silcd/server_internal.h.
7075 * Fixed silc_server_packet_broadcast to send correct broadcast
7078 * The channel key is now distributed to the local client as soon
7079 as it is received from the router (in router environment) so that
7080 no other packet may be sent for the channel until client has
7083 * silc_server_remove_channel_user now broadcasts the received
7084 Remove Channel User packet if it is not broadcast packet already.
7085 The router must broadcast to inform other routers about removed
7088 * Added users field into SilcPacketContext that is a reference count
7089 of the context. One can increase the reference count by calling
7090 silc_packet_context_dup which is now changed to just increase the
7091 reference count instead of duplicating the data. The reference
7092 count is decresed by calling silc_packet_context_free that will
7093 free the data after the reference count hits zero.
7095 For now on the packet context and everything allocated into it
7096 (including the raw packet from network) must be freed by calling
7097 the new silc_packet_context_free function. Added also new function
7098 silc_packet_context_alloc that must be used now to allocate the
7099 context. This also means that if a routine is asynchronous from
7100 silc_[client/server]_packet_parse_type the packet context must
7101 be duplicated by calling silc_packet_context_dup. Otherwise it
7102 gets free'd after silc_[client/server]_packet_parse_type returns.
7103 Also, one must remember that if packet is duplicated then its
7104 reference count must be decresed by calling the free function as
7105 many times as it was duplicated.
7107 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7108 from both client and server.
7110 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Made joining to a channel working in router environment.
7114 * Cleaned up JOIN command on server side and create function
7115 silc_server_command_join_channel internal routine to make the
7118 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Changed silc_command_pending list to SilcDList. Also, added
7121 `ident' field to SilcServerCommandPending structure to identify
7122 the reply and to call correct callback.
7124 Added silc_server_command_pending_check function to replace the
7125 corresnponding macro. The silc_command_pending list is not
7128 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7129 to set identifier to previously allocated Command Payload. It
7130 is used to set identifier for command when resending Command
7133 * Added silc_command_payload_encode_payload to encode Command
7134 Payload buffer from SilcCommandPayload structure.
7136 * Added silc_argument_payload_encode_payload to encode Argument
7137 payload buffer from SilcArgumentPayload structure.
7139 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Changed WHOIS command to support router connection on server side.
7142 The whois request is always sent to router unless the server is
7143 standalone server. After server has received the reply from the
7144 router will it send the reply to the client.
7146 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7147 broadcast received broadcast packet. The function is used only
7148 by router. The broadcast packet is always sent to the router's
7151 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7152 render given ID to printable string, for log files for example.
7154 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7156 * Made basic router to router connections working. At least they
7157 can now connect to each other but nothing really works the way
7158 they are supposed - yet.
7160 * Added new initiator token to RouterConnection configuration
7161 file in silcd/serverconfig.[ch]. It is used to tell whether we
7162 are the initiator to the remote router or whether we'll expect
7163 the other end to connect.
7165 * Moved registering of listener task to silc_server_init, hence
7166 the server starts listenning as soon as it is run, even if it
7167 does not have connections to other routers. Let's see how well
7170 * Changed default connection retry timeouts for more suitable in
7173 * Removed cipher and such arguments from silc_idlist_add_client
7174 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7175 Added new function silc_idlist_add_data to add the keys and stuff
7178 * Added SilcIDListData structure and added it to SilcClientEntry
7179 and SilcServerEntry as their first field in the structure. This
7180 way we can explicitly cast the ID entries to the SilcIDListData
7181 structure and get common data for the entries. In past, we had
7182 to first check what type of connection it is and then cast it to
7183 correct ID entry type. Now, we can directly cast the opaque
7184 pointer to the SilcIDListData (no matter what ID entry it actually
7185 is) and get the data needed.
7187 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7190 in some circumstances even if threre were timeout tasks, though not
7191 IO tasks, but tasks anyway. Now fixed.
7193 * Defined SilcServerConnection structure to hold connection specific
7194 stuff about directly connected servers and routers. The definition
7195 is currently in silcd/server_internal.h. I thought about having
7196 a bit more important role fro this struct but for now it is used
7197 only when connecting to other server (or router actually).
7199 * Added connecting retry support in server when connecting to
7200 router(s). The retry feature implement exponential backoff
7201 algorithm. Also, added SilcServerParams structure to hold default
7202 parameters for server. For now, it include these retry settings
7203 and are hard coded. After server is moded to be as Silc Server
7204 Library this structure will be more important.
7206 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7208 * Changed client librarys channel->clients table to SilcList and
7209 changed code accordingly.
7211 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7213 * Changed client's channel table to SilcList and changed code
7214 accordingly. Also changed SilcChannelClientEntry to include back-
7215 pointer to the channel so that client entry can use that structure
7216 as list as well and we have fast cross-reference to the channel.
7217 This change dramatically decreased the complexity of channel
7218 handling with client entry and vice versa (removed one extra
7219 loop when searching for channel entry from many functions).
7221 * Changed server->sim from table to SilcDList and changed code
7224 * NAMES command can now be used from user interface. It will show
7225 the user list on the channel, neatly.
7227 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7228 Code now saves realname of the user if it becomes available.
7230 * Renamed configure.in to configure.in.pre and made ./prepare
7231 script to automatically add correct version string to
7232 configure.in which it creates from configure.in.pre.
7234 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7236 * NAMES command reply now shows users mode with the nickname when
7239 * Moved silc_client_ch[u]mode[_char] functions from
7240 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7241 place sucks, they are utility functions and should be in some
7244 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7246 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7249 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7253 * Added TRQ (efficient deque and list library) into lib/trq. This is
7254 a very good list library that is currently used in the SILC. Defined
7255 SilcList API over the library because I didn't like the API very
7256 much. See lib/trq/silclist.h for the API and examples of how to
7257 use the API. Fixed various places in the code to use the new
7258 SilcList API. The SilcList is meant for lists that has a structure
7259 already defined as a list. It is not suitable to add just some
7260 context to the list (in TRQ, the context is the list actually).
7262 So, I defined SilcDList that can be used for the purpose where
7263 predefined list structure does not exit. This can be used as
7264 such list. Now some context just can be added to the SilcDList.
7265 Currently this list is not used in the SILC just yet, though there
7266 are a lot places where this can replace dynamically allocated
7267 tables and I will fix these places, later, to use SilcDList.
7268 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7269 and use TRQ internally).
7271 Also fixed some annoying warning messages that the original TRQ
7272 code generated. Also minor changes to TRQ's Makefile.in.
7274 * Added support for querying by Client ID to both WHOIS and
7275 IDENTIFY commands into server, as required by the protocol.
7277 * Removed method function pointers from SilcBuffer structure. They
7278 weren't used to anything and just increased the context size for
7279 no good reason. This change also made silc_buffer_alloc and
7280 silc_buffer_free functions inline functions.
7282 * Disabled command flooding detection support until it's fixed so
7283 that it accepts commands in but does not execute them more than once
7286 * Added silc_net_localhost(), to return local hostname, into
7287 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7288 that must be initialized before calling silc_client_init.
7290 * Added new function: silc_server_send_notify_on_channels to send
7291 notify messages to all channels client has joined. It is assured
7292 that the message is sent only once per client.
7294 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7295 lib/silcutil/silcutil.[ch] as silc_format function. The new
7296 function is generic and is used by server as well, not only by
7297 the logging routines.
7299 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7300 the provided version string was not acceptable. Added new function:
7301 silc_ske_check_version into lib/silcske/silcske.h. The function
7302 must be implemented by the application (client or server) and it
7303 does not reside in the SKE library. The function checks the version
7304 string remote end sent.
7306 * Added back pointers (to opaque context and to SilcSocketConnection)
7307 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7309 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7310 duplicate packet context structure.
7312 * Changed `notify' client operation to send same arguments as client
7313 receives from server except for ID's. ID's are mapped to correct
7314 ID entry and that is returned. Also, if channel entry is not sent
7315 by server but the notify is for channel the channel entry is sent
7316 to application (otherwise application doesn't know that it is for
7317 channel (library gets it from packet's Destination ID)).
7319 * Added silc_client_remove_from_channels into client library to
7320 remove a client from all channels it has joined to. Used when
7321 received SIGNOFF notify from server. Added also new function
7322 silc_client_replace_from_channels to replace old ID entry with
7323 new ID entry on all channels. Used when received NICK_CHANGE
7326 * Fixed ID Cache list handling in silc_idlist_get_client in
7327 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7328 to get (or query) client by ID.
7330 * Updated TODO list.
7332 * Added connection authentication status message defined by the
7333 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7334 support for these into the code in client and server side.
7336 * Added generic function silc_client_send_command to send any command
7337 with variable argument list. Application should use this function
7338 to send commands if the command functions provided by the library
7339 does not suite for the application's user interface needs.
7341 * Added new `failure' client operation. Application is notified about
7342 received failure packet if client is executing a protocol. In this
7343 case the protocol's execution has failed.
7345 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7346 is required by the protocol.
7348 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7349 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7352 * Added status flag to SilcSKE object to indicate realtime status
7353 of the SKE protocol.
7355 * Application receives now exactly same command reply arguments as
7356 the library receives from server. However, if ID is received the
7357 corresponding ID entry is returned to the application (eg. Client
7358 ID is mapped to correct SilcClientEntry entry and that is returned).
7359 Changed command_reply client operation due to this change.
7361 * Changed all ID's in commands and in command replys as ID Payloads.
7362 Change affected both client and server side codes.
7364 All ID's sent in SILC network (with execption of ID's in SILC
7365 Packet header) are sent in ID Payload to support variable length
7368 * Server now notifies nick changes and notifies all clients on
7369 the channels about the new nickname (about the new Client ID,
7372 * Implemented CMODE command to change channel modes. Supports all
7373 channel modes defined by the protocol specs except ban and invite
7374 lists. (Also, private channel key mode is supported but support for
7375 setting private channel key in client is missing, thus, this mode
7376 has no effect on client side (except that server requires that the
7377 client uses private channel key and normal channel traffic does not
7380 Also, invite mode works per se, but INVITE command does not work
7381 yet correctly, so you can set channel as invite only channel but
7382 inviting clients to the channel does not work (it is yet to be
7383 thought what's the best way to do it).
7385 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7386 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7387 Implemented CUMODE command to change user's mode on the channel.
7388 Supports all modes defined by the protocol specs.
7390 * Added NAMES command reply to return users modes on the channel.
7392 * Removed unnecessary and slow ciphers from lib/silccrypt.
7394 * Set SO_KEEPALIVE option to connection sockets by default.
7396 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7398 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7399 redefined the Notify Payload into protocol specs.
7401 * Added silc_id_payload_parse_id to get ID directly from raw
7404 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7406 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7407 accept searching by Client ID as well.
7409 * Added support for LEAVE and SIGNOFF notify types in client library.
7411 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7412 to parse ID Payload from raw data.
7414 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7416 * Added flags parameter into silc_ske_assemble_security_properties
7417 function in lib/silcske/silcske.[ch].
7419 * Changed notify client operation to fit better for notify messages
7420 sent by server. The notify payload received from server is now
7421 passed to the application (after parsing it to SilcNotifyPayload).
7422 It is application's responsibility to retrieve the arguments
7423 from the payload and show the message the way it wants. The message
7424 sent by server is implementation specific.
7426 * Changed public keys to comply with the protocol specification.
7427 Old public keys are not supported anymore and are not compatible.
7429 * Removed nickname from Channel Payload as the latest draft removed
7430 it. The client must resolve the nickname from the NAMES command
7431 reply received when it joined the channel.
7433 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7435 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * Fixed some errors in protocol specification drafts.
7439 * Created lib/silccore/silcnotify.c to implement Notify Payload
7440 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7441 generic payloads described by protocol specifications. The file
7442 includes implementations for ID Payload and Argument Payload.
7444 * Changed Command Payload implementation to use the new Argument
7445 Payload. Changed command_xxxx_payload to command_payload_xxxx
7446 to comply with SILC coding conventions.
7448 * Added suppport for Argument Payload handling in Notify Payload
7449 implementation as protocol requires it. Added the new support
7450 into server and client lib as well.
7452 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * Added support for multiple nicknames on same channel. [n] is
7455 added locally to the nickname if there are more than one same
7456 nicknames on the channel.
7458 * Server now sends all nicknames that matched WHOIS request.
7459 Client also shows the list received from server.
7461 * Added TOPIC command to client side. User can now set and show
7462 current topic on channel.
7464 * Added MOTD command to client and server. Also, server sends the
7465 motd when client connects to the server.
7467 * Changed version strings to comply ISO 8601.
7469 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7471 * Fixed protocol error handling in client library. It should now
7472 cope even if the SKE fails for some reason.
7474 * Made new protocol specification drafts for submitting to IETF.
7476 * Implemented TOPIC command to server in silcd/command.c.
7478 * Added two new notify types into lib/silccore/silcnotify.h:
7479 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7480 notify nickname change and topic setting/change on a channel.
7482 * API change of command_reply operation in client library. The
7483 application gets now the status type received from server as well.
7485 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7489 * Cras fixed and optimized the packet handling even further and
7490 it should work now. Minor change to the prototype of function
7491 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7493 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Added new function into lib/silcutil/silcschedule.[ch]:
7496 silc_schedule_with_fd to select() a specified fd. The function
7497 returns after timeout expires or data arrives or goes. The
7498 function is used by packet routines to wait that all data is
7499 received from network.
7501 * Fixed data reading from network in lib/silccore/silcpacket.c.
7502 The code now assures that all data is read from the fd and then
7503 continues packet processing. This was a bug fix since the code
7504 used to drop some data in some circumstances.
7506 * Added new function into lib/silcclient/client.[ch]:
7507 silc_client_start_key_exchange to start key exchange after
7508 connection has been established to server. The code internally
7509 now uses this funtion but its main purpose was to provide it
7510 for applications that perform their own connecting. After
7511 application has created a connection it merely calls this
7512 function to start the key exchange between client and server.
7513 The library takes care of everything else after that.
7515 Updated also lib/silcclient/README to explain the usage of
7518 * Do not send to application information that connection has
7519 been established. Application gets notified it by connect
7522 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7524 * Applied cras's patch to add silc_schedule_one function. The
7525 function runs scheduler once and returns.
7527 * Fixed the scheduler after cras messed it up. The timeout
7528 handling works now as it's supposed to work.
7530 * Added into lib/silccore/ silcnotify.h to include notify
7531 message types support. Changed silc_server_send_notify*
7532 functions, in server.[ch], to support those new notify types.
7533 Added the support for the notify types into client library,
7534 as well. Added new notify client operation into ops.h in
7537 * Changed silc_server_packet_send_to_channel to send normal
7538 packets instead of just channel message packets. The function
7539 is now used to send the notify packets to channels. It is not
7540 used to send channel message packets anymore, as server never
7543 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7544 va_arg()s as it seems to require it nowadays. I guess, if SILC
7545 is compiled with older va_arg() the new code should work anyway.
7547 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Splitted core library. Core library (lib/silccore) includes
7550 now only SILC protocol specific core (and common) components.
7551 Created new utility library (lib/silcutil) that includes more
7552 generic purpose stuff. The stuff for util library was taken
7553 from the old core library. This was minor and easy split.
7555 * Created SILC Client Library (lib/silcclient) that includes
7556 implementation of the SILC client without user interface. This
7557 was major move from silc/ directory. The code has been changed
7558 so that it is transparent towards the user interface. The
7559 silc/ directory includes now the same user interface as before
7560 and it uses the new client library. Read lib/silcclient/README.
7561 Basicly, the client library performs everything else related
7562 to SILC except user interface handling. Also, configuration
7563 files are considered to be part of user interface and library
7564 does not handle them.
7566 This change also changed a lot of structures, function naming etc.
7567 Most important change was that SilcClientWindow object was
7568 renamed to SilcClientConnection in the client library. Created
7569 also new file lib/silcclient/ops.h. Also added new files
7570 silc/local_command.[ch] and silc/client_ops.[ch].
7572 All these changes were made to make it easier for user interface
7573 designers to create what ever user interface for the SILC client
7576 It is also expected that the server will be moved to lib
7577 directory as well and SILC Server Library will be created;
7578 sometimes in the future.
7580 * Removed Local commands from lib/silccore/silccommand.h as
7581 they are application specific and new client library does not
7582 handle any of those anymore.
7584 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7585 old client implementation in silc/.
7587 * Added support for callback functions in SILC_LOG_* macros.
7588 Application can now set its own callbacks that will be called
7589 instead of using the default functions that will always print
7590 the debug messages to stderr (or stdout). Also, debugging can
7591 now be disabled by setting silc_debug to FALSE and re-enabled by
7592 setting it to TRUE. Note, that logging will still work even
7593 if debugging is disabled.
7595 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7596 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7597 silc_log_reset_debug_callbacks.
7599 * To enable debugging in silc client one must give now -d
7600 option on command line.
7602 * Changed silc_schedule_init to automatically allocate task queues
7603 if they are not allocated before calling it.
7605 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7607 * Added GMP 3.1 into math library.
7609 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7611 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7612 a channel in SILC network. The packet is used by servers and
7613 routers to notify other routers that user has left a channel.
7614 This little feature was missing until now. Added the feature
7615 to protocol specification as well.
7617 Added functions: silc_server_send_remove_channel_user and
7618 silc_server_remove_channel_user into server.[ch].
7620 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7621 lib/silccore/silcpacket.h. However, they are not implemented
7624 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Fixed joining to a channel and sending channel messages
7627 between server and router. The channel message sending should
7628 now work inside a cell.
7630 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Fixed the private message sending between server and router.
7633 The private message sending should now work inside a cell.
7635 * Added silc_server_replace_id into server.[ch] to replace
7636 existing ID in the SILC network.
7638 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7639 and silc_idlist_replace_server_id into idlist.[ch] in server.
7641 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7643 * Fixed the server to server connections. Server can again now
7644 connect to router. Router to router connections probably does
7647 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7649 * Added dynamic protocol registering support. Now protocols can
7650 registered and unregistered on the fly. Patch by cras.
7652 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7654 * Added lib/contrib directory to hold routines that some platforms
7655 don't have but are needed by SILC.
7657 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7658 into lin/contrib to provide getopt() and getopt_long() for
7659 those who don't have it.
7661 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7663 * Added AWAY command to client. When away message is set and
7664 client receives a private message packet the client automatically
7665 replies to the sender with the away message.
7667 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7668 bug seemed to be the cause of recent problems when compiling
7671 * Added version detection support to SKE protocol specification
7672 and added the new changes to the SKE implementation as well.
7673 There were other minor changes in the SKE protocol as well.
7675 Many changes in lib/silcske/silcske.[ch] and in
7676 lib/silcske/payload.[ch].
7678 * Added ^U functionality, clear input line. Patch from cras.
7680 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7682 * Mainly small bugfixes on core library. Fixed some debugging
7683 logging and buffer overflow in silclog.c.
7685 * Updated config.sub and config.guess on the distribution tree.
7687 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7689 * Added command lagging support in server. Client may execute
7690 commands now only once in two seconds.
7692 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7694 * Optimized packet reception. MAC computation and checking is now
7695 also more optimized. A lot previously duplicated code is now
7696 used as generic by both client and server.
7698 * Fixed key pair generation in clientutil.c
7700 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7702 * Added into lib/silccore/silcbufutil.[ch] new function;
7703 silc_buffer_realloc.
7705 * Moved generic packet sending/encryption functions to
7706 lib/silccore/silcpacket.[ch] from client and server. Some
7707 rewriting of the functions.
7709 * Moved all generic packet reception/decryption functions to
7710 lib/silccore/silcpacket.[ch] from client and server. The
7711 packet processing is now much cleaner in both client and server.
7712 These were major changes in both client and server.
7714 * Created many common functions in server to do packet sending.
7715 Previously code were duplicated a lot, this has been removed
7718 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7720 * Rewrote major parts of the ID cache system. Don't know
7721 whether it is better now or not but at least the API is more
7724 * Major rewrite on ID cache stuff on client because of the ID
7725 cache API changes. Added idlist.c to client.
7727 * Also major rewrite on ID cache stuff on server as well.
7728 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7729 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7730 in hand, instead they are all put into the ID cache system now.
7731 All server_idlist_* routines uses ID cache now instead of
7732 traversing its own lists (those lists does not exist anymore).
7733 SilcIDList though still exists. Also, SilcXXXEntry's are
7736 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7738 * Finally made the SKE implementation compliant to the protocol
7739 specification. All mp integers are now binary encoded as
7740 opposed being HEX encoded.
7742 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7745 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7746 functions: silc_[encode/decode]_pem. Also added function
7747 silc_encode_pem_file to PEM encode with newlines ('\n') for
7750 * SILC public keys are now encoded either PEM or binary. Same
7751 option is for private keys as well. By default private keys
7752 are binary encoded and public keys PEM encoded. Silly HEX
7753 encoding were removed.
7755 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7756 function to create fingerprints.
7758 * Fixed a bug in SHA1; does not change the original data anymore.
7760 * Partly implemented INFO command on client and server side.
7761 Fixed CLEAR command. Changes to SERVER command; show current
7762 server(s) when giving command without arguments. Added
7763 VERSION command to client.
7765 * Added check to server that unregistered connections cannot
7766 execute commands (unless it is specificly allowed).
7768 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7770 * Fixed screen refresh.
7772 * Fixed channel joining bug from client. On some circumstances
7773 client tried to join to a channel it had already joined.
7775 * Added public key verification process into client's protocol.c.
7776 The client now verifies the public key from user and saves
7777 it into ~./silc/serverkeys/ directory.
7779 Added into: clientutil.[ch]: silc_client_verify_server_key.
7781 * Changed SKE protocol's silc_ske_initiator_finish function
7782 to accept callback function that verifies the received public
7783 key. Removed old silc_ske_verify_public_key function.
7785 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7788 silc_pkcs_private_key[_data]_set.
7790 * Made the password and public authentication more cleaner in
7791 server's protocol.c.
7793 * Removed historic and obsolete protocol `channel_auth' from
7794 both client and server.
7796 * Removed wrong way of sending command status messages from
7797 server to client in server's command.c. The old way violated
7798 protocol specification.
7800 Changes to silccore/silccommand.[ch]: removed
7801 silc_command_encode_status_payload -> not needed anymore,
7802 changed silc_command_encode_payload_va to accept extra
7803 argument on variable argument list. The argument type must
7804 now be provided to the function. Also, added new function:
7805 silc_command_encode_reply_payload_va which is same as
7806 normal command_encode_payload_va except command status type
7807 is provided as extra argument.
7809 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7811 * Added ~./silc directory handling. The directory includes the
7812 public and private keys for the client.
7814 Added silc_client_check_silc_dir, silc_client_create_identifier
7815 and silc_client_load_keys.
7817 * Implemented SILC protocol compliant public key. Added public
7818 and private key saving to and loading from files.
7820 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7821 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7822 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7823 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7824 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7826 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7827 silc_pkcs_load_[public/private]_key.
7829 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7831 * Added silc_server_get_route (route.[ch]) to get connection
7832 data for the fastest route for given ID.
7834 * Implemented INVITE command on client and server. The command
7835 were re-defined in the SILC Protocol Specification and the
7836 implementation now complies with the specification.
7838 * Implemented PING command on client and server.
7840 * Implemented NAMES command on client and server. The server side
7841 supports currently only normal server not router server yet.
7842 Some changes to NAMES definition in SILC protocol specification.
7844 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7846 * Implemented LEAVE command on client and server.
7848 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7849 again. This change was made to the protocol as well. Server
7850 should not violate the protocol specification anymore.
7852 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7854 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7855 was tested. SOCKS4 was not but should work anyway.
