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

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

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

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

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

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

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

956 users list to SilcHashTable. The affected files are
957 lib/silcclient/idlist.[ch].
959 * Fixed a bug in hash table tarversing. While the hash table
960 is traversed with SilcHashTableList the table must not be
961 rehashed. It is now guaranteed that auto rehashable tables
962 are not rehashed while tarversing the list. Also defined that
963 silc_hash_table_rehash must not be called while tarversing
964 the table. Added function silc_hash_table_list_reset that must
965 be called after the tarversing is over. The affected files are
966 lib/silcutil/silchashtable.[ch].
968 * Changed all hash table traversing to call the new
969 silc_hash_table_list_reset in server and in client library.
971 * Added function silc_client_on_channel to return the

983 lists correctly. Affected file silcd/command.c.
985 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * When sending JOIN command to router for processing the
988 sender's old command identifier was not saved back to the
989 sender's command context, fixed now. The affected file is
992 * Create the key in JOIN command of the router did not return
993 the channel key, added check for this. Affected file is
996 * Fixed a channel ID update bug in JOIN command reply. Do
997 not directly upgrade the ID but call the function
998 silc_idlist_replace_channel_id if the ID was changed.
999 Affected file silcd/command_reply.c.
1001 * Fixed memory leaks from command calling if it would fail.
1002 Affected file silcd/command.c.

1029 functions. Affected file silcd/server.c.
1031 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1032 which ID was changed. This way the router will send the
1033 user list for the channel again, and server won't be in
1034 desync in some rare circumstances. Affected file is
1035 silcd/packet_receive.c.
1037 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1077 key exchange. Affected file silcd/server.c.
1079 * Do not reconnect on connection failure when SCONNECT was
1080 given. Affected files silcd/server.[ch].
1082 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1084 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1086 * Fixed the NICK command to always give the unformatted
1087 nickname to the one giving the NICK command. If unformatted
1088 nickname is cached already it will be formatted and the
1089 local entry will always get the unformatted nickname.
1090 Affected file lib/silcclient/idlist.c.
1092 * Fixed some double frees from client library commands.
1093 Affected file is lib/silcclient/command.c.
1095 * Fixed CUMODE command in server to assure that no one can
1096 change founder's mode than the founder itself, there was a
1097 little bug. Affected file silcd/command.c.
1099 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1101 * Removed the SilcClientCommandDestructor from the client
1102 libary, it is not needed anymore. Affected files are
1103 lib/silcclient/silcapi.h, command[_reply].[ch],
1104 client_notify, idlist.c.
1106 * Fixed GETKEY command to first resolve client, and then
1107 resolve the server only if the client was not found, instead
1108 of resolving both at the same time. Affected file is
1109 lib/silcclient/command.c.
1111 * Added silc_client_start_key_exchange_cb and lookup the
1112 remote hostname and IP address before starting the key
1113 exchange with server. The affected file is
1114 lib/silcclient/client.c.
1116 * The server's public key is now saved using the IP address
1117 of the server and not the servername for the filename.
1118 The hostname public key filename is checked as an fall back
1119 method if the IP address based filename is not found.
1121 Fixed the GETKEY command to save the fetched server key
1122 in correct filename.
1124 Print the remote server's hostname now when new key is
1125 received during connection process. Affected file is
1126 irssi/src/silc/core/client_ops.c.
1128 * Return always our own public key to the client if it asks
1129 for it with GETKEY command. Affected file silcd/command.c.
1131 * Removed the use_auto_addr variable from default config
1132 file since it was in wrong section. Affected file is
1135 * Fixed TOPIC_CHANGE notification to not route it when it
1136 was sent using silc_server_send_notify_to_channel function.
1137 Affected file silcd/command.c.
1139 * Fixed silc_server_send_notify_kicked to send the kicker's
1140 Client ID also, it was missing. Affected files are
1141 silcd/command.c, silcd/packet_send.[ch].
1143 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1145 * Do not save client history information in SERVER_SIGNOFF.
1146 Fixes the bug in normal server that it does not detect
1147 the client becoming valid after the server becomes back
1148 online. Affected file silcd/server_util.c.
1150 * Added `sock_error' field into the SilcSocketConnection
1151 context. When error occurs during socket operation (read
1152 or write) the error is saved. Added also new function
1153 silc_socket_get_error to return human readable socket error
1154 message. Affected files are lib/silcutil/silcsockconn.[ch],
1155 lib/silcutil/unix/silcunixsockconn.c, and
1156 lib/silcutil/win32/silcwin32sockconn.c.
1158 * The server now prints the socket error message in the
1159 signoff for client. Affected file silcd/server.c.
1161 * Fixed the `created' channel information sending from router
1162 to server in JOIN command. Checks now whether the channel
1163 really was created or not and set it according that.
1165 Fixed the JOIN command to use the client entry's current
1166 ID during the joining procedure instead of the one it sent
1167 in the command (it is checked though), since it can change
1168 between the packet processing and command processing, and
1169 would just case unnecessary pain in the client end. Affected
1170 file silcd/command.c.
1172 * Fixed a channel key payload sending to use correct channel
1173 ID when the server was forced to change the channel's ID by
1174 router. Router sent the key payload with the old Channel ID.
1175 Affected file silcd/packet_receive.c.
1177 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1179 * Call silc_server_save_channel_key only if the key payload
1180 was provided in the JOIN command's command reply. Affected
1181 file silcd/command_reply.c.
1183 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Fixed silc_mp_sizeinbase to return the value correctly with
1186 MPI. Affected file lib/silcmath/mp_mpi.c.
1188 * Fixed the stop_server signal to correctly stop the scheduler
1189 and gracefully stop the server when SIGTERM or SIGINT signals
1190 are received. Affected file silcd/silcd.c.
1192 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1194 * Simple handling of TERM and HUP signals. Also added some log
1195 flushing call around. Affected file is
1198 * Fixed small bugs in silclog.c. Now buffering output will take
1199 effect after 10 seconds since startup: This will ensure that
1200 no important startup messages are lost. Also output redirection
1201 will preserve original format ([Date] [Type] message).
1202 Affected file is lib/silcutil/silclog.c.
1204 * Added two options to the config file, in the logging section:
1205 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1206 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1208 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1210 * Do not print the warning about log files not being initialized
1211 more than once to avoid excess logging. Affected file is
1212 lib/silcutil/silclog.c.
1214 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1215 the SIM copying in make install in Makefile.am.pre.
1217 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1219 * Rewritten silclog APIs. Globally interesting changes follows:
1220 silc_log_set_files() changed to silc_log_set_file().
1221 silc_log_set_callbacks() changed to silc_log_set_callback().
1222 ROBOdoc documented silclog header file.
1223 SilcLogCb now returns bool to wether inihibit the default
1224 handler or not (to keep the old behaviour return always TRUE).
1225 The new APIs should also fix the problem of the
1226 silcd_error.log file that was written in the current directory.
1229 Log files streams will remain opened after silc_log_set_file()
1230 call, means less CPU usage notably on high traffic servers.
1231 File streams are now full buffered, and flushed to the disk
1232 every 5 minutes, lesses HD activity and CPU usage.
1233 Messages can be redirected, allowing admins to configure
1234 one single logfile for all server messages.
1235 the silc_log_quick global variable to activate fast-logging.
1236 Affected files lib/silcutil/silclog.[ch]
1238 * Changed some code to conform new silclog APIs. Affected
1239 files are doc/example_silcd.conf.in, silcd/server.c
1240 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1243 * Fixed a memory leak that could occur in some situations.
1244 Affected file silcd/serverconfig.c.
1246 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1248 * Added the silc_client_del_client to remove the client from
1249 all channels as well. Affected file lib/silcclient/idlist.c.
1251 * Fixed the client library to correctly remove the client
1252 from all channels when the client entry is being destroyed.
1253 Affected file lib/silcclient/client_notify.c, command.c.
1255 * Added auto-nicking support to the client library. If the
1256 applicatio now sets client->nickname it will be sent to the
1257 server after connecting by the library. This way for example
1258 SILCNICK (or IRCNICK) environment variables will have effect
1259 and always change the nickname automatically to whatever
1260 it is wanted. Affected file lib/silcclient/client.[ch].
1262 * Renamed silc_server_command_bad_chars to the
1263 silc_server_name_bad_chars and moved it to the
1264 silcd/server_util.[ch]. Added also new function
1265 silc_server_name_modify_bad to return nickname that
1266 includes bad characters as new nickname without those
1267 bad characters. This check and modify is now used in
1268 silc_server_new_client when the username is initially set
1269 as nickname, so it must be checked to be valid nickname.
1270 Affected file silcd/packet_receive.c.
1272 * The nickname length is now taken from the packet for real
1273 and not trusted to strlen() since it clearly can return
1274 wrong length for nickname including bad characters. This
1275 also applies to channel names. Affected file silcd/command.c.
1277 * Removed the lib/silcsilm/modules directory. Modules are now
1278 compiled into the lib/silcsim. Fixed the copying of the
1279 modules to follow symbolic links in Makefile.am.pre.
1281 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1283 * Fixed silc_string_regexify list creation. Fixes bugs with
1284 BAN and INVITE commands in server. The affected file is
1285 lib/silcutil/unix/silcunixutil.c.
1287 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Removed the command destructor entirely from the server's
1290 command and command reply routines. It is not needed, and
1291 its usage was buggy and caused crashes. Affected files are
1292 silcd/command[_reply].[ch].
1294 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * Cancel protocol and NULL sock->protocol if timeout
1297 occurred during protocol. Affected file silcd/server.c.
1299 * Cancel protocol timeouts always before calling the final
1300 callback, to assure that after final callback is called
1301 no other state will be called for the protocol anymore.
1302 Affected file silcd/protocol.c.
1304 * Print error log if incoming connection configuration could
1305 not be found. Affected file silcd/server.c.
1307 * Fixed JOIN command to correctly save the founder mode
1308 to the client on normal SILC server, when the channel
1309 was created by the router. Affected file silcd/command.c.
1311 * Fixed LIST command (hopefully) to send correct reply
1312 packets. Affected file silcd/command.c.
1314 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * The silc_packet_receive_process now returns FALSE if the
1317 read data was invalid packet, and TRUE if it was ok.
1319 The server now checks that if unauthenticated connection
1320 sends data and its processing fails the server will close
1321 the connection since it could be a malicious flooder.
1323 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1325 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Make sure the warning about error opening a log file is
1328 printed only once and not everytime it fails (produces
1329 too much useless log). Affected file lib/silcutil/silclog.c.
1331 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1333 * Made the silc_server_daemonise() function more readable.
1334 Affected file silcd/server.c.
1336 * Pid file is now optional, the user may comment it out from
1337 the config file. Removed define SILC_SERVER_PID_FILE, we
1338 don't need a default any longer. Affected file
1339 configure.in.pre, lib/Makefile.am.pre.
1341 * Make some use of the pid file. The server now dies at startup
1342 if it detects a valid pid file on his path. The server would
1343 die anyway in this circumstance, because of the bind() failure.
1344 Affected file silcd/silcd.c.
1346 * No longer compiling lib/dotconf.
1348 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Fixed JOIN command parsing not to crash. Affected file
1351 lib/silcclient/command.c.
1353 * Fied the NICK_CHANGE notify to add the new client entry
1354 even it is resolved. This removes an <[unknown]> nick
1355 thingy bug in the client. Affected file is
1356 lib/silcclient/client_notify.c.
1358 * Do not try to allocate 0 bytes (efence does not like it)
1359 in lib/silccore/silccomand.c when encoding payload.
1361 * Do not take IRCNICK as nickname in Irssi SILC client since
1362 it is not possible to set nickname before hand connecting
1363 the server (TODO has an entry about adding auto-nicking
1366 * Changed the silc_server_command_pending to check whether
1367 there already exists an pending entry with the specified
1368 command, command identifier and pending callback. This is
1369 to fix IDENTIFY and WHOIS related crashes that may register
1370 multiple pending commands with same identifier. Affected
1371 file silcd/command.c.
1373 * Fixed the server to reconnect to the router even if it
1374 was already reconnecting and EOF was received. This to
1375 fix a possibility that the server wouldn't ever try to
1376 auto-reconnect to the router. Affected file silcd/server.c.
1378 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Fixed the server's password authentication to use the
1381 length of the locally saved password, and not the one
1382 sent in the packet. Affected file silcd/protocol.c.
1384 * Fixed same password authentication problem in the
1385 Authentication Payload handling routines in
1386 lib/silccore/silcauth.c.
1388 * Yet another password authentication problem fixed with
1389 channel password handling in silcd/command.c.
1391 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * If first character of string in silc_parse_userfqdn is '@'
1394 then do not parse it. Affected file is
1395 lib/silcutil/silcutil.c.
1397 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Fixed minor bug in IDENTIFY command reply sending, which
1400 caused various weird problems during JOIN when it was
1401 resolving names for users. Affected file silcd/command.c.
1403 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Fixed the IDENTIFY command reply sending to chech better valid
1406 clients. It was possible to send incomplete list of replies.
1407 Affected file silcd/command.c.
1409 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Added silc_client_command[s]_[un]register functions now to
1412 dynamically register the commands in client library. Removed
1413 the static table of commands. This allows the client library
1414 to call commands without causing the application to know about
1415 what commands library has called.
1417 Removed the INFO command reply kludge to detect when the command
1418 was called by library. Now library use its own command reply
1419 function for INFO command.
1421 Added function silc_client_command_call to call a command.
1422 Application can use it to call command, not access the structure
1425 Now all commands that are sent by the client library (not
1426 explicitly sent by application) use own command reply functions.
1428 Affected files around lib/silcclient/ and in
1429 irssi/src/silc/core/.
1431 * Fixed the WHOIS command reply sending to chech better valid
1432 clients. It was possible to send incomplete list of replies.
1434 Fixed the WHOIS and IDENTIFY to send the request to router
1435 if normal server did not do it and did not find any results.
1437 Affected file silcd/command.c.
1439 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Moved the internal data from SilcClient context into its
1442 own file, not accesible to application. Affected files
1443 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1444 and other files in client library.
1446 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Added doc/examples installation target in Makefile.am.pre.
1451 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1454 commands the found client entry will be removed from the
1455 cache, after notifying application about the error. Affected
1456 file lib/silcclient/command_reply.c.
1458 * Changed the /MSG to check for exact nickname user gave, and
1459 not let `nick' match `nick@host' if it is only one found. Now,
1460 user must type the exact nickname (like nick@host2) even if
1461 there are no more than one same nicks found. This is to avoid
1462 a possibility of sending nickname to wrong nickname since
1463 `nick' could match `nick@host'. Affected file is
1464 irssi/src/core/silc-servers.c.
1466 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Do not print "you are now server operator" or similar when
1469 giving /away command. Affected files are
1470 irssi/src/silc/core/client_ops.c, silc-servers.h.
1472 * Made the silc_server_command_pending_error_check to send
1473 the same command reply payload it received back to the
1474 original sender of the command. This way all arguments
1475 that was received by the server will be received by the
1476 client too. Affected file silcd/command.c.
1478 * Added the silc_idcache_add to return the created cache entry
1479 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1481 * Add global clients to expire if they are not on any channel.
1482 This is because normal server will never know if they signoff
1483 if they are not on any channel. The cache expiry will take
1484 case of these entries. This is done by normal servers only.
1485 The affected files are silcd/command_reply.c,
1486 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1488 * If server receives invalid ID notification for WHOIS or
1489 IDENTIFY and the ID exists in the lists, it is removed.
1490 Affected file silcd/command_reply.c.
1492 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1493 in client then client entry that it matches is searched and
1494 the nickname is printed on the screen for user. Affected
1495 file irssi/src/silc/core/client_ops.c.
1497 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Use cache entry expire time in the LIST command reply to
1500 purge old entries from the cache after the LIST command
1501 reply has been received. This way we don't have non-existent
1502 entries in the cache for too long. Affected file is
1503 silcd/command_reply.c.
1505 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * If we are normal server, and we've not resolved client info
1508 in WHOIS or IDENTIFY from router, and it is global client,
1509 we'll check whether it is on some channel. If it is not
1510 then we cannot be sure about its validity and will resolve it
1511 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1512 file silcd/command.c.
1514 * Search channel by name (if possible) rather than by ID
1515 in IDENTIFY command's command reply. Affected file is
1516 silcd/command_reply.c.
1518 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1521 Updated specs and implemented it. Affected file silcd/command.c,
1522 silcd/packet_send.c and silcd/packet_receive.c.
1524 * Implemented the <founder auth> payload handling in the JOIN
1525 command. If provided all conditions for channel joining
1526 except requirement to provide correct passphrase can be
1527 overrided by the channel founder. Updated the protocol specs.
1528 Affected file silcd/command.c.
1530 Added support for founder auth in JOIN command in client
1531 library. Fixed the parsing of the JOIN command now to support
1532 all options as they should be. The affected file is
1533 lib/silcclient/command.c.
1535 * Optimized the WHOIS and IDENTIFY commands to send the request
1536 to router only if it includes nicknames or other names. If
1537 they include only IDs then check the local cache first before
1538 routing. Affected file is silcd/command.c.
1540 * Added channels topic announcements. Affected file is
1541 silcd/packet_receive.c and silcd/server.c.
1543 * Fixed the silc_server_send_notify_topic_set to really destine
1544 the packet to channel. Affected file silcd/packet_send.c.
1546 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1547 library. Affected file lib/silcclient/client_notify.c.
1549 * Added UMODE announcements. Affected file silcd/server.c.
1551 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Memory leak fixes in:
1555 lib/silcutil/silcsockconn.c
1556 lib/silcske/silcske.c
1557 lib/silcske/groups.c
1559 lib/silccrypt/silcpkcs.c
1560 lib/silccore/silccommand.c
1561 lib/silccore/silcidcache.c
1566 * ROBOdoc documented the lib/silcske/groups.h file and a
1567 bit changed the interface for better.
1569 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1571 * Update the client entry context in the ID cache after
1572 nick change. Affected file lib/silcclient/command.c.
1573 Fixes the CUMODE command when regaining founder privileges,
1574 and a little WHOIS problem.
1576 * Fixed silc_net_gethostbyname to correctly call the
1577 inet_ntop. Affected file lib/silcutil/silcnet.c.
1579 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1581 * Added IPv6 support checking to the configure.in.pre, added
1582 also --enable-ipv6 option to override the check. Affected
1583 file configure.in.pre.
1585 * The silc_thread_create now calls the start function
1586 directly if threads support is not compiled in. Removes
1587 ugly #ifdef's from generic code. Affected files are
1588 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1590 * Added silc_net_gethostby[name/addr]_async to asynchronously
1591 resolve. Affected files are lib/silcutil/silcnet.[ch].
1593 * Added support for rendering IPv6 based server, client and
1594 channel IDs. Affected file lib/silcutil/silcutil.c.
1596 * Added support for creating IPv6 based server IDs. Affected
1597 file is silcd/serverid.c.
1599 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1601 * Added silc_net_gethostby[addr/name] into the
1602 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1603 routines. Added silc_net_is_ip[4/6]. Affected file is
1604 lib/silcutil/unix/silcunixnet.c. All routines that take
1605 address as argument now supports both IPv4 and IPv6 addresses.
1607 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1609 * Fixed LIST command reply sending in server. Affected file
1612 * Server now sends the kicker's client ID in the KICK notify
1613 to the kicked client. Affected file silcd/command.c.
1615 * The client library now parses the kickers client ID and
1616 UI displays it. Affected files lib/silcclient/client_notify.c
1617 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1619 * Made all payload parsing function prototypes consistent.
1620 They all take now const unsigned char * and uint32 pair as
1621 the payload data instead of SilcBuffer. Changes all around
1622 the source tree. Other unsigned char* -> const unsigned char*
1623 changes around the tree as well.
1625 * Optimized SFTP client and server packet sending not to
1626 allocate new buffer for each packet but to recycle the
1627 first allocated buffer. Affected files are
1628 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1630 * Optimized the SFTP client to use SilcList instead of
1631 SilcDList for requests, because it is faster. Affected file
1632 is lib/silcsftp/sftp_client.c.
1634 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1635 into lib/silccore/silcid.[ch].
1637 Renamed silcpayload.[ch] into silcargument.[ch].
1639 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * If client entry is deleted with active key agreement
1642 session, abort the session.
1644 The silc_client_abort_key_agreement now calls the completion
1645 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1647 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1650 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1652 * Don't use __restrict in older GCC's. Affected file is
1653 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1655 * silc_net_localhost now attempts to reverse lookup the
1656 IP/hostname. Affected file lib/silcutil/silcnet.c.
1658 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1659 command. It can be used to gain founder privileges at
1660 the same time when joining the channel.
1662 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1663 kicker's client ID as well. Updated protocol specs.
1665 Defined that the server must send SILC_COMMAND_IDENTIFY
1666 command reply with error status to client who sent
1667 private message with invalid client ID.
1669 Updated the protocol specification.
1671 * Added silc_server_send_command_reply to send any
1672 command reply. Affected file silcd/packet_send.[ch].
1674 * Added silc_id_payload_encode_data to encode ID payload
1675 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1677 * The server now send IDENTIFY command reply with error
1678 status if client ID in private message is invalid. Affected
1679 file silcd/packet_receive.c.
1681 * Save the server key file with server's IP address in
1682 the filename instead of hostname. The affected file is
1683 irssi/src/silc/core/client_ops.c.
1685 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1690 * Added libtool support for compiling shared objects in
1691 lib/silcsim. Affected file configure.in.pre and
1692 lib/silcsim/Makefile.am. Original patch by cras.
1694 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Pid file configuration, and server's config file fixes
1697 patch by toma. Updated CREDITS file.
1699 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Fixed silc_client_channel_message to not try to decrypt
1702 the message twice if it resolved the destination client
1703 information. This could cause of dropping one channel
1704 message. Affected file lib/silcclient/client_channel.c.
1706 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1709 lib/silcclient/client.c. This function is used when the SILC
1710 Client is run under some other scheduler, or event loop or
1711 main loop. On GUI applications, for example this may be
1712 desired to used to run the client under the GUI application's
1713 main loop. Typically the GUI application would register an
1714 idle task that calls this function multiple times in a second
1715 to quickly process the SILC specific data.
1717 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1719 * Fixed silc_server_drop() for dropping the supplementary
1720 groups as well, this could cause a security hole on some
1723 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1728 * Write PID file after dropping privileges. Added -F option
1729 to run server on foreground. A patch by debolaz.
1730 Affected files silcd/server.c, silcd/silcd.c.
1732 * Fixed MOTD to return the MOTD file server name. Affected
1733 file silcd/command.c.
1735 * Added INFO command reply handling to the Irssi SILC Client.
1736 Affected file irssi/src/silc/core/client_ops.c.
1738 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1740 * Fixed the silc_idcache_list_* routines to really support
1741 the dynamic list. Fixes a crash. Affected file is
1742 lib/silccore/silcidcache.c.
1744 * Fixed the LIST command reply to really call LIST command's
1745 pending callbacks. Affected file silcd/command_reply.c.
1747 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * Update conn->local_entry->nickname after giving NICK
1750 command. Affected file lib/silcclient/command.c.
1752 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1754 * Added the [pid] option to the silcd configuration file
1756 Affected files: serverconfig.[ch] and silcd.c
1758 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Save fingerprint in WHOIS command reply in server.
1761 Affected file silcd/command_reply.c.
1763 * Fixed NICK commands pending callback registration.
1764 Affected file lib/silcclient/command.c.
1766 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Use ++server->cmd_ident when sending commands in server,
1769 instead of random number. Affected file silcd/command.c.
1771 * Fixed GETKEY command reply to call actually GETKEY pending
1772 command callbacks. Affected file silcd/command_reply.c.
1774 * A bit stricter check for nicknames. Check for same nickname
1775 in NICK command also. Affected file silcd/command.c.
1777 * Do not call INFO command everytime client ID changes, only
1778 during first connecting. Affected file lib/silcclient/client.c.
1780 * Set the new nickname only after successful command reply for
1781 NICK command is returned by server. Affected file
1782 lib/silcclient/command.c.
1784 * Remove nicknames from nicklist during server_signoff notify.
1785 Should fix /NAMES bit more. The affected file is
1786 irssi/src/silc/core/silc-channels.c.
1788 * Added `fingerprint' field to the SilcIDListData in the
1789 silcd/idlist.h to hold the fingerprint of the client's
1792 Send the fingerprint of the client's public key in WHOIS
1795 Affected files silcd/command.c, and silcd/idlist.[ch].
1797 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1798 create fingerprint from given data.
1800 * Show the fingerprint of the client's public key in WHOIS.
1801 Affected files irssi/src/module-formats.[ch] and
1802 irssi/src/silc/core/client_ops.c.
1804 * Format the multiple same nicknames also during JOIN and
1805 NICK_CHANGE notifys. Affected file is
1806 lib/silcclient/client_notify.c.
1808 * Do not print error on screen for invalid private message
1809 payload since it can come if someone is sending private
1810 messages with wrong key. Affected file
1811 lib/silccore/silcprivate.c.
1813 * Fixed multiple concurrent /PING crash. Affected file
1814 lib/silcclient/command.c.
1816 * Changed the wrong ID encoding. All IP addresses must be
1817 in MSB first order in encoded format. They were encoded
1818 wrong and was in LSB format. Affected files are
1819 silcd/serverid.c, lib/silcutil/silcutil.c.
1821 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1823 * Call the `connect' client operation through the scheduler
1824 in case of error. Affected file lib/silcclient/client.c.
1826 * Call the `failure' client operation even if the error
1827 occurred locally during a protocol. Affected file is
1828 lib/silcclient/protocol.c.
1830 * Added support of sending LIST command to router from normal
1831 server. This way normal server can get list of all channels
1832 in the network too. Fixed the channel list sending in the
1833 server too. Affected files are silcd/command.c, and
1834 silcd/command_reply.[ch].
1836 * Added silc_server_update_channels_by_server and
1837 silc_server_remove_channels_by_server. They are used during
1838 disconnection of primary router and in backup router protocol.
1839 Affected file silcd/server_util.[ch], silcd/server.c and
1840 silcd/server_backup.c.
1842 * Fixed channel adding to global list in IDENTIFY command
1843 reply in server. Affected file silcd/command_reply.c.
1845 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * If the incoming packet type is REKEY or REKEY_DONE process
1848 that packet always synchronously. Fixes yet another MAC
1849 failed error on slow (dialup) connections. Affected file
1850 lib/silcclient/client.c and silcd/server.c.
1852 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * Call check_version SKE callback for initiator too. Affected
1855 file lib/silcske/silcske.c.
1857 * Implemented fix for security hole found in the SKE that was
1858 fixed in the specification few days back; the initiator's
1859 public key is now added to the HASH value computation.
1860 Added backwards support for the old way of doing it too, for
1861 old clients and old servers. Affected file is
1862 lib/silcske/silcske.c.
1864 * Enabled mutual authentication by default in SKE. If initiator
1865 is not providing mutual authentication the responder will
1866 force it. This will provide the proof of posession of the
1867 private key for responder. The affected files are
1868 lib/silcclient/protocol.c and silcd/protocol.c.
1870 * Do not cache anymore the server's public key during SKE.
1871 We do mutual authentication so the proof of posession of
1872 private key is done, and if the server is authenticated in
1873 conn auth protocol with public key we must have the public
1874 key already. Affected file silcd/protocol.c.
1876 * Added new global debug variable: silc_debug_hexdump. If
1877 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1878 file lib/silcutil/silclog.[ch].
1880 * Fixed compilation warning due to char * -> const char *.
1881 Affected files lib/silcutil/silcnet.h, and
1882 lib/silccore/silcauth.[ch].
1884 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Fixed CMODE command when new channel key was created. If
1887 the creation failed the old key was removed. Next time giving
1888 same command would crash the server since the old key was
1889 freed already. Affected file silcd/command.c.
1891 * Fixed the silc_server_announce_get_channels to not crash
1892 on reconnect. Affected file silcd/server.c.
1894 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1896 * Added silc_log_set_debug_string function to set a regex
1897 string to match for debug output. Only the function names,
1898 or filenames matching the given debug string is actually
1899 printed. This way it is possible to filter out those debug
1900 strings that user is not interested in.
1902 Fixed a bug in silc_string_regexify.
1904 Affected files lib/silcutil/silclog.[ch], and
1905 lib/silcutil/unix/silcunixutil.c.
1907 * Changed the -d options in both server and Irssi SILC client
1908 to take the debug string as argument. Affected files
1909 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1911 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Added silc_hash_babbleprint to create a Bubble Babble
1914 Encoded fingerprint. The encoding is developed by Antti
1915 Huima (draft-huima-babble-01.txt), and it creates human
1916 readable strings out of binary data. Affected file
1917 lib/silccrypt/silchash.[ch].
1919 * Print the babble print now in addition of fingerprint as well
1920 in Irssi SILC client. Affected files are
1921 irssi/src/fe-common/silc/module-formats.[ch],
1922 irssi/src/fe-common/silc/core/client_ops.c.
1924 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Fixed a security problem found in SKE. The initiator's
1927 public key too is now added to the HASH hash value creation
1928 which is signed by the responder to create the SIGN value.
1929 This will prevent anyone in the middle to lie to the responder
1930 about the initiator's public key. If this is done now, the
1931 man in the middle will get caught. Updated the protocol
1934 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Better installation directory handling. Configure module
1937 paths and other paths automatically to example_silc* files
1938 in doc/. A patch by toma.
1940 * Fixed compiler warning from MPI library, and from SILC RNG.
1943 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1944 It can be configured with ./configure. A patch by toma.
1946 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Find correct make to use in prepare-clean. A patch by
1949 toma. Affected file prepare-clean.
1951 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1953 * Added irssi variables use_auto_addr, auto_bind_ip,
1954 auto_bind_port and auto_public_ip.
1956 * Changed the interface for silc_client_send_key_agreement
1957 in lib/silcclient/silcapi.h
1961 irssi/src/silc/core/silc-core.c
1963 lib/silcclient/silcapi.h
1964 irssi/src/silc/core/silc-channels.c
1965 lib/silcclient/client_keyagr.c
1968 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Added silc_pkcs_public_key_compare to compare two
1971 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1973 * Check that the client who set the founder mode on the
1974 channel is the same client that is giving the founder
1975 mode to itself. It is done by comparing the saved public
1976 key (it is saved even in the authentication is passphrase).
1977 Affected file silcd/command.c.
1979 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Do not process packet for disconnected socket connection.
1982 Affected file lib/silccore/silcpacket.c.
1984 * Process the DISCONNECT packet through scheduler in the
1985 client library. Affected file lib/silcclient/client.c.
1987 * Fixed the silc_client_packet_parse to not to increase
1988 the packet sequence number if the conn->sock and the
1989 current socket connection is not same. This can happen
1990 for example during key agreement when the conn includes
1991 multiple socket connections (listeners). Affected file
1992 lib/silcclient/client.c.
1994 * The sender of the file transfer request now provides also
1995 the pointer (listener) for the key exchange protocol. If
1996 the listener cannot be created then it sends empty key
1997 agreement and lets the receiver provide the listener.
1999 Added `local_ip' and `local_port' arguments to the
2000 silc_client_file_send. If they are provided they are used,
2001 if not then it will attempt to find local IP address, if
2002 not found or bind fails then the remote client will provide
2005 Affected files are lib/silcclient/client_ftp.c and
2006 lib/silcclient/silcapi.h.
2008 * Extended the FILE SEND command to support defining the
2009 local IP and port for key exchange listener. They are
2010 optional. Affected file irssi/src/silc/core/silc-servers.c.
2012 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Defined to WHOIS command reply the sending of fingerprint
2015 of the client's public key (if the proof of posession of the
2016 corresponding private key is verified by the server).
2017 Updated to the protocol specification.
2019 * Added support of receiving the client's public key's
2020 fingerprint in command reply in client library. Affected
2021 file is lib/silcclient/command_reply.c, and
2022 lib/silcclient/idlist.[ch].
2024 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Do not send over 128 chars long nickname to the server
2027 in NICK command. Affected file lib/silcclient/command.c.
2029 * Do not send over 256 chars long channel names to the server
2030 in JOIN command. Affected file lib/silcclient/command.c.
2032 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Assure that silc_server_close_connection cannot be called
2035 twice for same socket context. Affected file is
2038 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Send error message to application if opening file for
2041 writing during file transfer fails. Affected file is
2042 lib/silcclient/client_ftp.c.
2044 Remove all file transfer sessions for a client that we're
2045 removing from ID cache.
2047 Affected file is lib/silcclient/client_ftp.c.
2049 * Fixed silc_net_addr2bin to return correct address. Affected
2050 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2052 * Fixed file transfer session removing on signoff notify.
2053 Affected file irssi/src/silc/core/silc-servers.c.
2055 * Added the SilcClientFileError to be returned in the monitor
2056 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2057 Affected file lib/silcclient/silcapi.h.
2059 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * Fixed a crash in silc_client_ftp_free_sessions and
2062 silc_client_ftp_session_free_client. Affected file
2063 lib/silcclient/client_ftp.c.
2065 * Added `disabled' field in the SilcChannelEntry in the server
2066 to indicate if the server entry is disabled. Affected file
2067 silcd/idlist.h, silcd/command[_reply].c.
2069 * SILC server adds now /var/run/silcd.pid everytime it is
2070 started. Affected file silcd/silcd.c.
2072 * Added silc_server_packet_send_clients to send a packet to
2073 the provided table of client entries. Affected file
2074 silcd/packet_send.[ch].
2076 * Fixed a crash in client resolving in client_prvmsg.c in
2077 client library. Affected file lib/silcclient/client_prvmsg.c.
2079 * Do not actually remove the client directly from ID cache
2080 during SERVER_SIGNOFF, but invalidate it. This way we
2081 preserve the WHOWAS info for the client. Affected file
2082 silcd/server_util.c.
2084 * Fixed SERVER_SIGNOFF notify handling in the server. The
2085 server is now able to process incoming SERVER_SIGNOFF notify
2086 for a server that it doesn't even know about. It will remove
2087 the clients provided in the notify. Affected file
2088 silcd/packet_receive.c.
2090 * Check for partial packet in data queue after every packet that
2091 was found from the queue. Return and wait for more data if
2092 there is partial data in queue. Affected file is
2093 lib/silccore/silcpacket.c.
2095 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2097 * Added SilcClietFileError enum to indicate error in
2098 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2099 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2100 Affected files lib/silcclient/silcapi.h and
2101 lib/silcclient/client_ftp.c.
2103 * Check that newsize in silc_buffer_realloc is larger than
2104 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2106 * Added better monitor of file transfers. It now monitors
2107 key agreement protocol during the file transfer too. Added
2108 error reporting too. Affected files
2109 irssi/src/silc/core/silc-servers.c,
2110 irssi/src/fe-common/silc/module-formats.[ch].
2112 * Wrote a help file for FILE command.
2114 * Added silc_rng_global_get_byte_fast to get not-so-secure
2115 random data as fast as possible. Random data is read from
2116 /dev/urandom if available and from the SILC RNG if not
2117 available. It is used in padding generation. Affected file
2118 lib/silccrypt/silcrng.[ch].
2120 * All packets in client library are now processed synchronously.
2121 Optimized packet processing a lot. Affected file
2122 lib/silcclient/client.c.
2124 * All server connection packets are processing synchronously
2125 now in server, to optimize packet processing. Affected file
2128 * Include files are installed now only in Toolkit distribution
2129 if make install is given. Affected files: all Makefile.am's.
2131 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Assure that silc_client_notify_by_server_resolve does not
2134 resolve the client information multiple times. If it cannot
2135 be found by the first it cannot be found at all. Affected
2136 file lib/silcclient/client_notify.c.
2138 * Fixed WHOWAS command reply calling. Affected file
2139 lib/silcclient/command_reply.c.
2141 * Removed all references to silc_idlist_get_client from the
2142 Irssi SILC client since that call is internal call used by
2143 the library. The Irssi SILC client will use now client
2144 retrieval functions found in silcapi.h.
2146 * Fixed a bug in resolving nickname info before sending
2147 private message. It used freed memory. Affected file
2148 irssi/src/silc/core/silc-servers.c.
2150 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2152 * Assure my_channels statistics cannot go negative in server.
2153 Affected files silcd/server.c, silcd/server_util.c.
2155 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2169 * Added silc_net_localip to return local host's IP address.
2170 Affected file lib/silcutil/silcnet.[ch].
2172 * If key exchange or rekey protocol is active for a connection
2173 parse all packets syncronously since there might be packets
2174 in packet queue that we are not able to process without first
2175 processing packets before them. Affected file silcd/server,
2176 lib/silcclient/client.c.
2178 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2179 whether library should continue processing the packet.
2180 Affected file lib/silccore/silcpacket.h.
2182 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2211 lib/silcutil/silcutil.[ch].
2213 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Resolve the client info when received private message or
2216 channel message for a client which nickname we don't know.
2217 Affected files lib/silcclient/client_prvmsg.c and
2218 lib/silcclient/client_channel.c.
2220 * Do not crash in /KEY if client is not connected. Affected
2221 file irssi/src/silc/core/silc-channels.c.

2226 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2227 is incomplete and is being resolved, it won't be resolved
2230 Make sure also that USERS command reply does not resolve
2231 twice information. Affected file is
2232 lib/silcclient/command_reply.c.
2234 Make sure that silc_client_get_clients_by_list does not
2235 resolve twice same information.
2237 * Check for valid client->id in the silc_server_free_client_data.
2238 Affected file silcd/server.c.
2240 * Fixed /GETKEY nick@server not to crash if the server entry
2241 is not found. Affected file lib/silcclient/command.c.
2243 * Fixed the silc_server_check_cmode_rights to check the
2244 requested modes correctly. Affected file silcd/command.c.

2248 * Better checks for non-printable chars in nick added.
2249 Affected file silcd/command.c.
2251 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Call the silc_server_udpate_servers_by_server in the
2254 primary router that comes back online in the backup resuming
2255 protocol. Otherwise it routes packets wrong. Affected file
2256 silcd/server_util.[ch], silcd/server_backup.c.
2258 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2261 lib/silcutil/silcbuffmt.[ch].
2263 * Redefined the SILC packet header to include the padding
2264 length. Affected file lib/silccore/silcpacket.[ch].
2266 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2267 length for maximum padding up to 128 bytes). Affected
2268 file lib/silccore/silcpacket.h.
2270 * Removed all backwards support for old 0.5.x MAC thingies.
2271 The SILC packet header change makes it impossible to be
2272 backwards compatible.
2274 * Send the ENDING packet with timeout in the backup resuming
2275 protocol. This is to assure that all routers has connected
2276 to the primary router. Affected file silcd/server_backup.c.
2278 * Changed the RNG to take the first IV from random data. It
2279 used to take it from zero actually. Changed the RNG also
2280 to use /dev/urandom during session. /dev/random is used
2281 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2283 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Changed the SILC packet header to have the first two bytes
2286 (the packet length) encrypted. Affected files aroung the
2287 code tree, lib/silccore/silcpacket.[ch]. Removed the
2288 SilcPacketCheckDecrypt callback. It is not needed anymore
2289 since the silc_packet_receive_process will determine now
2290 whether the packet is normal or special.
2292 * Implemented the unidirectional MAC keys. Affected files
2293 lib/silcske/silcske.c, silcd/protocol.c and
2294 lib/silcclient/protocol.c.
2296 * Implemented the packet sequence number to the MAC computation.
2297 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2298 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2299 lib/silcclient/protocol.c.
2301 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Allow backup router to announce servers. All servers
2304 announced by backup router are added to the global list
2305 automatically. Update hte server's socket to our primary
2306 router also when backup router announces a server.
2307 Affected file silcd/packet_receive.c.
2309 * Do not update the client->router in the function
2310 silc_server_udpate_clients_by_server if the client is on
2311 global list. We might fail to find any specific server
2312 for locally connected clients and local cell clients. They
2313 should still use the `from' and not `to' as client->router.
2314 This fixes backup router resuming protocol. Affected file
2315 silcd/server_util.c.
2317 * Decrease channel statistics count only if the channel
2318 deletion worked. Affected files are silcd/server.c and
2319 silcd/server_util.c.
2321 * Added silc_server_update_servers_by_server to update origin
2322 of all server entries. Used during backup router protocol.
2323 Affected files silcd/server_util.[ch], silcd/server.c. and
2324 silcd/backup_router.c.
2326 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2327 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2328 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2329 lib/silccrypt/silchmac.c.
2331 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Assure that router cannot reroute the same channel message
2334 to the sender. Affected file silcd/packet_receive.c.
2336 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Made better checks that the channel message is not sent
2339 to the router it came from. Affected file is
2340 silcd/packet_send.c. Fixed memory leak too.
2342 * Announce informations for incoming router connection, but
2343 only after checking if it is replaced by backup router.
2344 Affected file silcd/packet_receive.c.
2346 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Fixed the backup resuming protocol to work in multiple
2349 router environment. Affected file silcd/server_backup.c.
2351 * Route packet only to one router in the function
2352 silc_server_packet_send_to_channel. Affected file is
2353 silcd/packet_send.c.
2355 * Fixed silc_server_send_notify_dest to set the broadcast
2356 flag. Fixed the silc_server_send_notify_topic to actually
2357 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2358 Affected file silcd/packet_send.c.
2360 * Changed the SFTP Filesystem interface. Changed the
2361 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2362 the filesystem operation function. The SilcSFTPFilesystem
2363 is now a context that is allocated by all filesystem allocation
2364 functions and it already includes the operations structure
2365 and filesystem specific context. It is given as argument
2366 now to the silc_sftp_server_start. This made the interface
2367 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2368 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2370 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * Changed the backup router adding and getting interfaces
2373 in the server. The router that will be replaced by the
2374 specified backup router is now sent as argument. Affected
2375 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2378 * Added silc_net_addr2bin_ne to return the binary form of
2379 the IP address in network byte order. Affected files
2380 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2382 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Check for existing server ID in silc_server_new_server
2385 and in silc_server_connect_to_router_final and remove the
2386 old entry if it exists. Affected file silcd/packet_receive.c,
2389 * Send the channel message always to only one router, either
2390 in upstream or downstream. Affected file is
2391 silcd/packet_send.c.
2393 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * Wrote the definition of the backup resuming protocol to the
2396 protocol specification.
2398 * Removed one redundant channel key generation from normal
2399 server during joining procedure. Removed one redundant
2400 channel key sending from server to router during joining
2401 procedure. Affected file silcd/command.c.
2403 * Made minor bugfixes to the backup router resuming protocol.
2404 Affected file silcd/server_backup.c, server.c.

2409 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2412 * Implemented the backup resuming protocol that is used to
2413 resume the primary router position in the cell after the
2414 primary router comes back online. Affected files
2415 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2416 and silcd/server_util.[ch].
2418 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Sleep two (2) seconds after sending QUIT command to server.
2421 Affected file lib/silcclient/command.c.
2423 * Assure that if outgoing data buffer is pending do not force
2424 send any data. Affected file silcd/packet_send.c.
2426 * Assure that if outgoing data buffer is pending do not force
2427 send any data. Affected file lib/silcclient/client.c.
2429 * Implemented the backup router support when the primary router
2430 goes down. The servers and routers can now use the backup
2431 router as new primary router without loosing connectivity.
2433 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2436 in the server to indicate disabled entry. All data read
2437 from the connection will be ignored and no data is sent
2438 for entry that is disabled. Affected files are
2439 silcd/idlist.h, silcd/server.c.
2441 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Created SFTP client and server test programs in the
2444 lib/silcsftp/tests directory.
2446 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Implemented memory filesystem (virtual filesystem) for
2449 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2452 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Implemented the SFTP (SSH File Transfer Protocol) to the
2455 lib/silcsftp. It includes SFTP client and SFTP server
2458 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Moved lib/silccore/silcprotocol.[ch] to the
2461 lib/silcutil library.
2463 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2464 take variable argument list pointer as argument. Affected
2465 file lib/silcutil/silcbuffmt.[ch].
2467 * Added silc_buffer_set function that is used to set data
2468 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2469 Affected file lib/silcutil/silcbuffer.h.
2471 * Changed various routines in the core library to use the new
2472 silc_buffer_set instead of allocating new buffer only for
2475 * Added 64-bit value formatting and unformatting support to the
2476 silc_buffer_[un]format routines. Affected file is
2477 lib/silcutil/silcbuffmt.[ch].
2479 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2480 to includes/bitmove.h.
2482 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * Fixed channel user mode saving in client library. Affected
2485 file lib/silcclient/command[_reply].c.
2487 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Defined the file transfer to the SILC Protocol. Added
2490 new packet type SILC_PACKET_FTP and defined File Transfer
2491 Payload. The mandatory file transfer protocol is SFTP
2492 (SSH File Transfer Protocol). Affected file in addition
2493 of the internet draft is lib/silccore/silcpacket.h.
2495 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2496 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2497 is used as part of backup router protocol when the primary
2498 router of the cell is back online and wishes to resume
2499 the position as primary router.
2501 * Redefined the MAC generation keys in the protocol. The
2502 same key is not used anymore in both direction. Both
2503 direction will now use different keys for sending and
2504 receiving. This fixes a potential security flaw. This
2505 change causes incompatibilities in the protocol.
2507 * Redefined also the MAC computation from the packet.
2508 An packet sequence number is now added to the MAC
2509 computation. This prevents possible replay attacks against
2510 the protocol. This change too causes incompatibilities
2513 Added `sequence' field to the SilcPacketContext to hold
2514 the current sequence number for the packet.
2516 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2518 * Added `created' field to the SilcIDListData in the file
2519 silcd/idlist.h to indicate the time when the entry was
2522 * Added `created' field to the SilcChannelEntry too. Affected
2523 file silcd/idlist.h.
2525 * Added `creation_time' aguments to all the announcement functions
2526 in the server. If it is provided then only the entries that
2527 was created after the provided time frame are actually
2528 announced. Affected file silcd/server.[ch].
2530 * The protocol says that the Channel ID's IP address must be
2531 based on the router's IP address. Added check for this in
2532 the silc_server_new_channel when processing incoming New Channel
2533 Payload. Affected file silcd/packet_receive.c.
2535 * Print out the correct version with --version in SILC client.
2536 Affected file irssi/src/silc/core/silc-core.c.
2538 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Fixed WHOWAS command to check for completnes of the client
2541 entry always, not just when the command is coming from client.
2542 Affected file silcd/command.c.
2544 * Added new function silc_server_packet_queue_purge to purge the
2545 outgoing data queue to the network. After the function returns
2546 it is guaranteed that the outgoing packet queue is empty.
2547 Affected file silcd/packet_send.[ch].
2549 * Purge the outgoing packet queue in the rekey protocol's final
2550 callback to assure that all rekey packets go to the network
2551 before quitting the protocol. Affected file silcd/server.c.
2553 * Added silc_client_packet_queue_parse as similar function as
2554 in server to the client library. The affected file is
2555 lib/silcclient/client.c.
2557 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Splitted silcd/server.c and created silcd/server_util.[ch]
2560 for utility functions.
2562 * Added new socket flag SILC_SF_DISABLED to indicate that the
2563 connection is open but nothing can be sent to or received from
2564 the connection. Affected file lib/silcutil/silsockconn.[ch].
2565 The checking for disabled socket is checked in the low level
2566 silc_socket_write and silc_socket_read functions.
2568 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Allow only nicknames and channel names that fits into the
2571 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2573 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * When processing JOIN command reply in server check that if
2576 the channel exists in our global list we'll move it the local
2577 list. Affected file silcd/command_reply.c.
2579 * Fixed the check whether client is joined on the channel already
2580 in JOIN command. Affected file lib/silcclient/command.c.
2582 * Fixed the JOIN command reply to check whether the channel
2583 already exists. Affected file lib/silcclient/command_reply.c.
2585 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Added silc_ske_status_string to map the SKE error numbers
2588 to readable strings. The affected files are
2589 lib/silcske/silcske[_status].[ch].
2591 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Do not show the private channels on the WHOIS channel list
2594 as it is not allowed by the protocol. The affected file is
2597 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Assure that the packet length digged from the actual packet
2600 is something sensible in the silc_packet_decrypt_rest_special
2601 in lib/silccrypt/silcpacket.c.
2603 * Free and NULL the allocated pointer in silc_hmac_alloc if
2604 the HMAC allocation fails. The affected file is
2605 lib/silccrypt/silchmac.c.
2607 * Print the selected security properties to the log files in
2608 the server. Affected file silcd/protocol.c.
2610 * Add SKE's reference counter even if calling the completion
2611 callback manually. Otherwise it goes negative, although it
2612 does not cause any problems. The affected file is
2613 lib/silcske/silcske.c.
2615 * Remove the client entry with short timeout after giving the
2616 KILL command. Affected file lib/silcclient/command.c.
2618 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2619 case all found clients are already disconnected (WHOWAS would
2620 found them) in the server. Affected file silcd/command.c.
2622 * Update the last_receive (time of last data received) to be
2623 updated only when received private or channel message so that
2624 the idle time showed in WHOIS makes more sense.
2626 * Added boolean field `valid' in to the SilcClientEntry in the
2627 client library to indicate whether the entry is valid or not.
2628 This fixes the nickname change bug on channel when changing
2629 the nickname to be same than the old (like nick to Nick) the
2630 nickname formatter doesn't set the new nick anymore to Nick@host.
2631 Affected file lib/silcclient/idlist.[ch].
2633 * Now actually fixed the nickname changing on disconnection.
2634 Added new function silc_change_nick to the Irssi SILC Client.
2635 Affected file irssi/src/silc/core/client_ops.c,
2636 irssi/src/silc/core/silc-nicklist.[ch].
2638 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Check that the public key exists in the GETKEY command before
2641 trying to encode it. Affected file silcd/command.c.
2643 * Print some notifications on received public keys with GETKEY
2644 command in the Irssi SILC Client. Affected files are
2645 irssi/src/fe-common/silc/module-formats.[ch],
2646 irssi/src/silc/core/client_ops.c.
2648 * Use IDENTIFY command to resolve the server information in the
2649 GETKEY command instead of INFO command. Affected file
2650 lib/silcclient/command.c.
2652 * All command reply functions in the client library now calls
2653 the pending command reply callbacks even if an error has
2654 occurred. The server has done this a long time and now it was
2655 time to move the client library to this as well. Now all
2656 errors can be delivered back to the pending command reply
2657 callbacks if necessary. Affected files are
2658 lib/silcclient/command[_reply].[ch].
2660 * Change the nickname on disconnection back to the username
2661 because in reconnect the server will enforce it to it anyway.
2662 Affected file irssi/src/silc/core/silc-servers.c.
2664 * Fixed a config file parsing bug in the Irssi SILC client.
2665 Affected file irssi/src/silc/core/clientconfig.c.
2667 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * When printing the channel mode on JOIN, verify that the
2670 channel key and channel's HMAC are valid. Affected file
2671 irssi/src/silc/core/client_ops.c.
2673 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2676 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2677 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2679 * Removed channel key rekey task deleting from the function
2680 silc_server_save_channel_key. Affected file silcd/server.c.
2681 Added explicit timeout task context instead that is used to
2682 delete the task if we are registering a new task before the
2683 new task has elapsed.
2685 * When channel key rekey occurs the client library now saves
2686 the old channel key for a short period of time (10 seconds) and
2687 is able to use it in case some is still sending channel
2688 messages encrypted with the old key after the rekey. Affected
2689 file lib/silcclient/[idlist.h|client_channel.c].
2691 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Added check to the silc_server_new_id_real to not accept
2694 new ID if it is the sender's own ID. Affected file is
2695 silcd/packet_receive.c.
2697 * Assure that we do not announce ourself or the one we've
2698 sending our announcements when we're router and are announcing
2699 servers to our primary router. Affected file silcd/server.c.
2701 * Fixed silc_server_command_identify_check_client to assemble
2702 correct WHOIS packet. It send corrupted WHOIS packet and
2703 caused problem with router to router connections. Affected
2704 file silcd/command.c.
2706 Fixed also silc_server_command_whois_check the same way
2707 as for the IDENTIFY command.
2709 * Added new SilcIDListStatus to the server in the SilcIDListData
2710 structure. The status now includes the current status of
2711 the entry (like registered, resolved etc.). Affected file
2712 silcd/idlist.[ch]. Defined a bunch of different status types
2713 as well. This replaced the old boolean registered field as well.
2715 Added resolve_cmd_ident field to the SilcClientEntry structure
2716 too so that if the entry is for example being resolved so
2717 another command may attach to the same pending command reply
2718 without requiring to resolve the same entry again. This concept
2719 should optimize the WHOIS and the IDENTIFY resolving under
2720 heavy load by taking away unnecessary resolving for entries
2721 that are being resolved already.
2723 Added support for adding multiple pending commands for one
2724 command idenfier. Affected file silcd/command[_reply].[ch].
2726 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2727 before deleting the data. Otherwise the hash table will have
2728 freed data in comparison functions. Affected file is
2729 silcd/command_reply.c.
2731 * Fixed silc_idlist_replace_client_id to add the new entry to
2732 the cache with NULL nickname. Otherwise there will be invalid
2733 memory as the nickname after the nickname is freed. Affected
2734 file silcd/packet_receive.c.
2736 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2737 saved into wrong slots because the previous number of entries
2738 was not taken into account. Affected file silcd/idlist.c.
2739 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2741 * If we are router and we receive JOIN notify to a channel that
2742 does not have any users then notified client is marked as the
2743 channel founder, as it is it. The affected file is
2744 silcd/packet_receive.c
2746 * Added to the extended hash table API's table_del_*ext functions
2747 the destructor as argument too, so that the caller can decide
2748 which destructor to use or whether to use destructor at all.
2749 Affected file lib/silcutil/silchashtable.[ch].
2751 * Fixed ID Cache purging. It actually deleted the entries from
2752 the hash table after the data was freed. The hash table ended
2753 up comparing freed memory. The affected file is
2754 lib/silccore/silcidcache.c.
2756 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Fixed Irssi SILC client's KILL command's HELP syntax.
2760 * The USERS command now resolves the detailed user information
2761 if the userinfo field is missing. Affected file is
2762 lib/silcclient/command_reply.c.
2764 * Do not print error in silc_file_read if the read file does
2765 not exist. Just silently return NULL. Affected file is
2766 lib/silcutil/silcutil.c.
2768 * Fixed the silc_log_output to not wine about NULL filename
2769 and to not create some bogus " " filename. Affected file is
2770 lib/silcutil/silclog.c.
2772 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Fixed various printing bugs on the user interface in the
2775 Irssi SILC Client. Minor changes that were forgotten from
2778 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Fixed the configure.in.pre and the compilation and distribution
2781 environment to support the new autoconf 2.52. That version is
2782 now required to compile the CVS trunk.
2784 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2787 to generally parse user@fqdn format strings. Affected file
2788 lib/silcutil/silcutil.c.
2790 * Added nickname_format and nickname_force_format fields to the
2791 SilcClientParams structure. The first one defines the format
2792 for the nicknames that the library will enforce if the receives
2793 multiple same nicknames. The second one is boolean value and
2794 can be used to force the library to always enforce the format
2795 to the nicknames regardles whether there are multiple nicknames
2796 or not. This configurable formatting was employed to flexibly
2797 support accessing multiple nicknames from the user interface.
2798 The userinterface can now set the nicknames to what ever format
2799 they prefer. Affected file lib/silcclient/silcapi.h.
2801 Added function silc_client_nickname_format to the file
2802 lib/silcclient/idlist.c. It performs the nickname formatting.
2804 Added new field `hostname´ to the SilcClientEntry context.
2805 It holds the hostname of the client. Affected file is
2806 lib/silcclient/idlist.h.
2808 * Irssi SILC Client sets the nicknames in nick@hostn format.
2809 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2810 irssi/src/silc/core/silc-core.c.
2812 The WHOIS printing now also shows both the real nickname and
2813 the formatted nickname so that user knows how to access the
2814 user if there are multiple same nicknames cached. Affected
2815 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2816 printing formatting too to take the hostname now as a separate
2817 argument. The Affected file is
2818 irssi/src/fe-common/silc/modules-formats.[ch].
2820 * Changed the silc_client_get_clients_local to accept the formatted
2821 nickname as argument. It accepts the real nickname too but the
2822 formatted nickname can be used to find the true entry from
2823 multiple entries. Affected file lib/silcclient/silcapi.h and
2824 lib/silcclient/idlist.c.
2826 * Added nickname_format_parse field to the SilcClientParams.
2827 It is a callback function provided by the application to parse
2828 the nickname out of the formatted nickname string. The library
2829 calls it to get the nickname from the formatted string. Since
2830 the application generally knows better the format of the nickname
2831 string it parses it instead of the library, even though library
2832 encodes the formatted string. If the callback function is not
2833 provided then the library will use the string as is. The
2834 affected file is lib/silcclient/silcapi.h.
2836 * All the nickname strings passed to the client library in
2837 commands are now expected to be formatted nickname strings.
2838 If the command does not support the formatted nickname string
2839 it will assume that the sent string is the actual nickname.
2840 Affected file lib/silcclient/command.c.
2842 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Added public key authentication support to OPER and SILCOPER
2845 commands in the client library. Affected file is
2846 lib/silcclient/command.c.
2848 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Changed the get_auth_methdod client operation to be asynchronous.
2851 It can be async if the application resolves the authentication
2852 method from the server during the negotiation. Added new
2853 SilcGetAuthMeth completion callback that the application will
2854 call after resolving the authentication method.
2856 Added function silc_client_request_authentication_method that
2857 the application can use to resolve the authentication method
2858 from the server. Added also SilcConnectionAuthRequest callback
2859 that the library will call after the server has replied. The
2860 application can call this function if it does not know the
2861 current authentication method.
2863 Affected files are lib/silcclient/client.c and
2864 lib/silcclient/silcapi.h.
2866 * The Irssi SILC client now automatically resolves the authentication
2867 method incase any configuration information is not present (and
2868 currently there never is). The affected file is
2869 irssi/src/silc/core/client_ops.c.
2871 * Fixed public key authentication from the client library.
2872 Affected file lib/silcclient/protocol.c. Changed also the
2873 protocol specification about the public key authentication in
2874 the connection authentication protocol. The actual data to be
2875 signed is now computed with a hash function before signing.
2877 * Fixed the public key authentication from the server as well.
2878 Affected file silcd/protocol.c.
2880 * Removed the mlock()'s from the memory allocation routines.
2881 Affected file lib/silcutil/silcmemory.c. The ./configure does
2882 not check anymore for the mlock(). Affected file is
2885 * Fixed USERS command in server to allow the execution of the
2886 command for private and secret channels if the client sending
2887 the command is on the channel. Affected file silcd/command.c.
2889 * Fixed silc_client_get_clients_local to return the clients
2890 count correctly. It could return wrong value. Affected file
2891 lib/silcclient/idlist.c.
2893 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2896 types. The assembler optimizations seemed not to like 64-bit
2897 data types. The assmebler optimizations thus are now enabled
2898 also for BSD systems as opposed to only enable them for Linux.
2900 * Do not check for threads at all on BSD systems. Affected
2901 file configure.in.pre.
2903 * Removed -n and -h options from the Irssi SILC Client since
2904 they are not used in silc.
2906 * Fixed the prime generation to assure that the first digit
2907 of the generated random number is not zero since our conversion
2908 routines does not like number strings that starts with zero
2909 digit. If zero digit is seen the random number is regenerated.
2910 This caused some corrupted RSA keys when the zero first digit
2911 was met. Affected file lib/silcmath/silcprimegen.c.
2913 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Fixed WIN32 configuration in the ./configure script.
2916 Fixed to include xti.h on environments that has it.
2917 Patches by Carsten Ilchmann and andrew.
2919 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Changed the silc_id_create_client_id to be collision
2922 resistant. It is now assured that there cannot be created
2923 two same client ID's. I suspect that some weird bugs in
2924 the server were actually caused by duplicate Client IDs.
2925 Affected file silcd/serverid.[ch]. A router receiving
2926 new ID now also assures and informs the sending server
2927 if the ID caused collision.
2929 * Changed the silc_id_create_channel_id to also assure that
2930 there are no collisions.
2932 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Statement about ignoring the Mutual Authentication flag when
2935 performing rekey with PFS was a bit misleading. It is ignored
2936 if it was set in the initial negotiation, it cannot be even
2937 set in the rekey. Fixed in the ke-auth draft. Started the
2938 new versions of the protocol drafts in the doc/.
2940 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Fixed a bug in silc_client_command_identify_save when saving
2943 new channel information. The channel name was no duplicated
2944 and caused crash on exit. Affected file is
2945 lib/silcclient/command_reply.c.
2947 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * Fixed the getkey command handling in the server. Send just
2950 empty OK reply to the sender if the key could not be fetched
2951 (but everything else was ok, like the key just was not available).
2952 Changed the public key parameter to optional in the protocol
2953 specs so that empty OK reply can be sent. Affected file
2956 Added a message to Irssi SILC client to tell to user if the
2957 server did not return a public key.
2959 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Fixed a channel key regeneration bug. It registered new
2962 timeout tasks exponentially until all system resources were
2963 used. Affected file silcd/server.c.
2965 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Added the SILC Document generator to the scripts/silcdoc.
2968 It can be used to generate the Toolkit Reference Manual out
2969 of the source tree. Internally it will also use the RoboDoc
2970 generator now imported in util/robodoc.
2972 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Added couple of return's in rekey protocol if error orccurred
2975 during the protocol. The execution must be terminated.
2976 Affected file silcd/protocol.c. Also, terminate the protocol
2977 always with timeout.
2979 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * The client's Client ID was created initally from the wrong
2982 nickname (it could have been in format nick@host) in the
2983 silc_server_new_client. Affected file silcd/packet_receive.c
2985 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Added some SILC_LOG_ERROR's to various error conditions
2988 if client could not be added to ID cache. Affected files
2989 silcd/packet_receive.c and silcd/server.c.
2991 * When client's sock->user_data is freed, NULL also the
2992 client->router and client->connection pointers. Added check
2993 for these pointers being NULL to various places around the
2994 code. Affected file silcd/server.c.
2996 * Added client->data.registered == TRUE checks to various
2997 places around the code to assure that unregistered client's
2998 are not handled when it is not allowed. Affected file
3001 * Added `bool registered' fields to all
3002 silc_idlist_[server|client]_get_* routines to indicate whether
3003 the fetched client needs to be registered or not. Affected
3004 file silcd/idlist.[ch].
3006 * Add your own entry as registered to the ID cache in the
3007 server. Affected file server.c.
3009 * Fixed a bug in silc_server_new_server. The SilcServer was
3010 set as the new server's context instead of SilcServerEntry.
3011 This naturally caused some weird bugs.
3013 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Do not delete the channel rekey task when adding it
3016 for in silc_server_create_channel_key.
3018 * Changed the silc_server_create_channel_key to return
3019 TRUE or FALSE to indicate the success of the channel key
3022 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * Fixed MSVC++ project files and added missing files to
3025 Makefiles under win32/.
3027 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Do not add TCP_NODELAY flag if the operating system
3030 does not have it defined. Affected files are
3031 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3033 * Fixed buffer overflow from Irssi SILC Client. Affected
3034 file irssi/src/fe-common/core/themes.c.
3036 * Fixed double free in client library in the file
3037 lib/silcclient/client.c when disconnecting from server.
3039 * Applied double free patch from cras to Irssi SILC client.
3040 Affected files irssi/src/core/[modules/expandos].c
3042 * Fixed the disconnection handling to Irssi SILC Client.
3043 The application must call silc_client_close_connection
3044 in ops->connect client operation in case of failure of
3045 the connection. Affected file is
3046 irssi/src/silc/core/client_ops.c.
3048 * Do not set sock->protocol to NULL in the function
3049 silc_client_close_connection after executing the protocol's
3050 final callback since the sock might not be valid anymore.
3051 Affected file lib/silcclient/client.c.
3053 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Do not enable SILC_THREADS if the linking with libpthread
3056 did not happen. Affected file configure.in.pre.
3058 * Added notion to protocol specification that server must
3059 verify the sent authentication payload with CMODE when
3060 setting the channel founder key. Implemented it to the
3061 server. Affected file silcd/command.c.
3063 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * Added _EXTRA_DIST SILC distribution variable to the
3066 distributions file. It is used to conditionally add extra
3067 files or directories to the specific distribution. Affected
3068 files ./prepare, Makefile.am.pre and distributions.
3070 Removed the `_' from the start of the distribution names.
3073 * Added README.WIN32 for instructions to compile the Toolkit
3076 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Fixed a double free in disconnection in the server. Affected
3079 file is silcd/server.c.
3081 * Fixed the lib/silcske/groups.c to work now also with GMP
3082 MP library. The string conversion did not work when using
3083 specific base and the base is indicated in the string as well.
3085 * Created win32/ directory which now includes MSVC++ specific
3086 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3087 It will appear only in the toolkit distribution
3089 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3091 * Changed the key material distribution function in case when
3092 the hash output is too short. The data is now concatenated
3093 a bit differently than it used to. Made the change to the
3094 SKE protocol specification.
3096 * Added better GMP detection to configure.in.pre. A patch
3099 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Fixed a minor bug in SKE that might cause some problem on
3102 some platforms. Affected file lib/silcske/silcske.c.
3104 * Added the cookie checking for initiator in the SKE. It checks
3105 that the responder returns the sent cookie unmodified. The
3106 affected file is lib/silcske/silcske.c. Added new SKE
3107 error type INVALID_COOKIE that can be sent during the
3108 negotiation. Fixed some memory leaks as well.
3110 * Added the "invalid cookie" error message to Irssi SILC client's
3113 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Added `task_max' field to the SilcClientParams to indicate
3116 the maximum tasks the scheduler can handle. If set to zero,
3117 default values are used. Affected file lib/silcclient/silcapi.h.
3119 * Fixed memory leaks in silc_client_close_connection. Affected
3120 file lib/silcclient/client.c.
3122 * Added silc_client_del_client_entry to client library to free
3123 all memory of given client entry. Affected file is
3124 lib/silcclient/idlist.[ch].
3126 * Added new functions silc_client_del_channel and
3127 silc_client_del_server to delete channel and server entries.
3128 Affected file lib/silcclient/[silcapi.h/idlist.c].
3130 * Removed silc_client_del_client_by_id from silcapi.h.
3132 * Fixed the INFO command to return the server's own info
3133 correctly when querying by Server ID. Affected file is
3136 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Removed the non-blocking settings in WIN32 code in the
3139 silc_sock_[read/write] and added SleepEx instead. Affected
3140 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3141 of input data is now checked with FIONREAD and ioctlsocket.
3143 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Call silc_schedule_task_del_by_context in the
3146 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3147 Affected file lib/silccore/silcprotocol.c.
3149 * Call silc_protocol_cancel for active protocols in the
3150 silc_server_close_connection if the funtion
3151 silc_server_free_sock_user_data has not been called.
3152 Affected file silcd/server.c.
3154 * Generic tasks cannot be deleted using the del_by_fd
3155 task deleting function since generic tasks does not match
3156 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3158 * Added a notion to SILCOPER help file that the SILCOPER works
3159 only on router server, not on normal server.
3161 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3163 * Added for WIN32 support for the new scheduler as well.
3164 Affected file lib/silcutil/win32/silcwin32schedule.c.
3166 * Fixed the SHA1 implementation to work on various platforms.
3168 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3171 API. It is part of the scheduler now. Everything else is
3172 as previously but some functions has changed their names.
3173 Checkout the lib/silcutil/silcschedule.h for the interface.
3174 Updated all applications to use the new interface. Affected
3175 files are lib/silcutil/silcschedule.[ch].
3177 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Found a bug in the SKE implementation. The HASH value,
3180 specified by the protocol, was not computed correctly. The
3181 public key of the responder was not added to the computation
3182 even though it is mandatory. Affected file lib/silcske/silcske.c.
3183 This unfortunately causes incompatibilities with older
3184 clients and servers.
3186 * Added WIN32 specific network init and uninit functions:
3187 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3188 the Winsock2. Affected file lib/silcutil/silcnet.h and
3189 lib/silcutil/win32/silcwin32net.c.
3191 * Set the socket always to nonblocking mode on WIN32 after
3192 reading data or writing data. Affected file is
3193 lib/silcutil/win32/silcwin32sockconn.c.
3195 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Fixed various compilation problems under WIN32. Affected
3198 files lib/silcutil/win32/silcwin32thread.c and
3199 lib/silcutil/win32/silcwin32schedule.c.
3201 * Removed all _internal.h #includes from public header
3202 files. Internal headers must never be included from
3205 Removed also the lib/silcske/payload_internal.h file.
3207 * All include files that may be needed (public and some others
3208 included by the public headers) by application developers are
3209 now copied to the ./includes directory. It does not copy any
3210 internal headers. Affected file Makefile.defines.pre and all
3211 Makefile.am's under lib/ and subdirs.
3213 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3215 * Do not change the ~/.silc directory's permissions automatically.
3216 Affected file irssi/src/silc/core/clientutil.c.
3218 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Do not cancel the protocol in silc_server_close_connection
3221 it might cause recursion. Now cancelled in the function
3222 silc_server_free_sock_user_data. Affected file silcd/server.c.
3224 * Fixed the silc_server_remove_clients_by_server to regenerate
3225 the channel keys correctly finally. Added also new function
3226 silc_server_remove_clients_channels to actually do it.
3227 Affected file silcd/server.c.
3229 * Fixed the silc_server_new_channel to not crash by giving
3230 wrong router to the new channel. Affected file is
3231 silcd/packet_receive.c.
3233 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3236 which is given as argument to the silc_client_alloc now.
3237 It can be used to configure the client and set various parameters
3238 that affect the function of the client.
3240 * The USERS command in server did not check whether the channel
3241 is private or secret. Affected file silcd/command.c.
3243 * Added new argument to the USERS command in protocol specification.
3244 The USERS command now can take the channel name as argument
3245 as well. Added support for this in client and server and
3246 updated the protocol specs.
3248 * Completed the GETKEY command in client. It can be now used
3249 to fetch also servers public key not only some clients.
3250 Affected files lib/silcclient/command[_reply].c.
3252 * Added silc_client_get_server to return server entry by the
3253 server name. Affected files lib/silcclient/silcapi.h and
3256 * Redefined the IDENTIFY command in protocol specification to be
3257 more generic. It now can be used to query information about
3258 any entity in the SILC Network, including clients, servers and
3259 channels. The query may be based either the entity's name
3260 or the ID. Added support for this in both client and server.
3262 Affected files silcd/command.c and lib/silcclient/command.c
3263 and command_reply.c.
3265 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3266 the _from_client and _from_server functions. Affected file
3269 * Added silc_client_get_channel_by_id_resolve to the file
3270 lib/silcclient/silcapi.h to resolve channel information by
3271 its ID. Added also silc_client_get_channel_by_id that
3272 does not resolve it from the server.
3274 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Added SilcServerEntry context into the client library
3277 to represent one server. The INFO command now allocates
3278 these to save the resolved server info. For now on the
3279 client library will also keep information about servers,
3280 connected and resolved with INFO.
3282 The INFO command now allocates the SilcServerEntry context
3283 and saves the server info there. The COMMAND_REPLY in
3284 the INFO now returns the parameters to application in
3285 same order as defined in the protocol specification.
3287 The entries are cached in the client->server_cache.
3289 * The INFO command is now issued after received the Client ID
3290 from the server. Affected file lib/silcclient/client.c.
3292 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3293 to the application as the mode changer might be server.
3294 It is guaranteed that NULL is not returned anymore to the
3295 application. Affected file lib/silcclient/client_notify.c.
3297 The ID Type is now also passed to the application so that
3298 it can check whether the returned entry is SilcClientEntry
3301 Added new function silc_client_get_server_by_id to return
3302 the server entry by ID. Affected files are the
3303 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3305 * Do not create the channel in the Irssi SILC Client when issuing
3306 the JOIN command but when received the sucessful JOIN command
3307 reply. Otherwise the channel might get created even though we
3308 could not join it. The Affected file is
3309 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3311 * Fixed a channel joining bug in router. The router must also
3312 check the channel modes, invite and ban lists etc. when serving
3313 the JOIN command sent by normal server. Affected file is
3314 silcd/command.c. The router now resolves the client's
3315 information from the server who sent the JOIN command if it
3316 does not know it, and processes the JOIN command only after
3319 * Changed the SilcCommandCb to take new argument; void *context2.
3320 Affected file lib/silccore/silccommand.h
3322 The second argument in the command callbacks in the server now
3323 includes the SilcServerCommandReplyContext if the command was
3324 called as pending command callback from the command reply.
3325 Otherwise it is NULL. When called as pending the status of the
3326 command reply will be checked and if it was erronous the
3327 error will be sent to the original sender of the command.
3328 This way the client always receives the error messages even
3329 though the server was actually the one who received the error
3330 when it resent the command to router, for example. Affected
3331 files silcd/command[_reply].[ch].
3333 * Fixed sending WHOWAS command's error message to client if
3334 the requested client could not be found. It was missing.
3337 * Changed the CMODE and CUMODE commands reply arguments in the
3338 protocol specification. The Channel ID is now sent in both
3339 of the commands to identify the channel. Implemented this
3340 new feature to the client and server. Affected files
3341 lib/silcclient/command_reply.c and silcd/command.c.
3343 * Made better checks for invite and ban lists in the JOIN
3344 command in server. Affected file silcd/command.c.
3346 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3348 * The server now performs the incoming host IP/DNS lookup
3349 using the silc_socket_host_lookup and thus does not block
3350 the server anymore. Affected file silcd/server.c.
3352 * Completed the multi-thread support for SILC Scheduler in
3353 the lib/silcutil/silcschedule.c.
3355 * Fixed the configure.in.pre to detect the pthread correctly
3358 * Fixed a deadlock in silc_task_queue_wakeup in the file
3359 lib/silcutil/silctask.c.
3361 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Added new function silc_schedule_wakeup that is used in
3364 multi-threaded environment to wakeup the main thread's
3365 schduler. It needs to be used when a thread adds a new task
3366 or removes a task from task queues. After waking up, the
3367 scheduler will detect the task queue changes. If threads
3368 support is not compiled in this function has no effect.
3369 Implemented the wakeup mechanism to both Unix and WIN32
3370 systems. Affected files are lib/silcutil/silcschedule.[ch],
3371 lib/silcutil/unix/silcunixschedule.c and the
3372 lib/silcutil/win32/silcwin32schedule.c.
3374 * Added new function silc_task_queue_wakeup to wakeup the
3375 scheduler by the specified task queue. Affected file
3376 lib/silcutil/silctask.[ch].
3378 * The silc_socket_host_lookup_start now wakes up the scheduler
3379 after adding the timeout task. Affected file is
3380 lib/silcutil/silcsockconn.c.
3382 * The silc_socket_host_lookup is synchronous now if the threads
3383 support is not compiled in. However, the callback is still
3384 called asyncronously through the scheduler, anyway. Affected
3385 file lib/silcutil/silcsockconn.c.
3387 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Added new function silc_socket_host_lookup to perform
3390 asynchronous IP and FQDN lookups for the socket connection.
3391 Affected files lib/silcutil/silcsockconn.[ch].
3393 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3396 that may or may not compile the mutex support in.
3398 Changed the silc_mutex_alloc interface. It allocates the
3399 mutex now to the sent pointer and returns TRUE or FALSE.
3401 Affected file lib/silcutil/silcmutex.h.
3403 * Wrote the SILC Task Queue interface to support multi-threads.
3404 Affected file lib/silcutil/silctask.[ch].
3406 * Wrote the SILC Scheduler to support multi-threads. Affected
3407 file lib/silcutil/silcschedule.c.
3409 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3412 in lib/silcutil/win32/.
3414 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Defined SILC Mutex API and SILC Thread API and implemented
3417 them for Unix. Affected files are
3418 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3419 lib/silcutil/unix/silcunixmutex.c and
3420 lib/silcutil/unix/silcunixthread.c.
3422 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * Fixed the silc_server_remove_clients_by_server's channel
3425 key re-generation. The hash table handling was incorrect
3426 and would not work with many channels. Affected file is
3429 * Fixed some memory leaks around the server code.
3431 * Rewrote the silc_server_get_users_on_channel to support IPv6
3432 based Client ID's. Affected file silcd/server.c.
3434 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3435 specification. However, a separate document must be written
3436 to define the detailed signing procedure and the payload
3437 associated with the flag. Defined the flag to the
3438 lib/silccore/silcchannel.h as well.
3440 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3442 * Changed the dynamic tables to static size tables in the
3443 lib/silccrypt/silchmac.c.
3445 * Removed GCC dependencies from the code. A patch by cras.
3447 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3449 * Do not show the error "Error receiving packet bla bla"
3450 in server if it really was not an error (-2 means that reading
3451 is pending). Affected file silcd/server.c.
3453 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Fixed a possible crash in silc_server_remove_clients_by_server
3456 in silcd/server.c. Fixed there also some memory leaks.
3458 * Fixed the silc_idlist_replace_client_id. It could replace
3459 wrong key in the hash table. Affected file silcd/idlist.c.
3461 * Do not check whether there are global users on the channel
3462 if the channel->global_users is FALSE. Affected functions
3463 silc_server_remove_from_one_channel and
3464 silc_server_remove_from_channels in silcd/server.c. Also,
3465 do not check if the removed client is local as we can be
3466 sure that global client was not removed from the channel
3467 and checking for global users is not needed.
3469 * The silc_server_remove_clients_by_server now re-generates
3470 the channel keys correctly for those channels that had
3471 clients removed from them. Affected file silcd/server.c.
3473 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Found the reason of random crashes in the server. We weren't
3476 ignoring the SIGPIPE signal (which can be sent in write())
3477 and it crashed the server. Affected file silcd/silcd.c.
3479 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Assure that sock->user_data is not NULL in the function
3482 silc_server_packet_send in silcd/packet_send.c.
3484 * Disconnect the remote connection if it could not be added
3485 to any ID lists in the server. The affected file is
3488 * Check in silc_server_packet_send[_real/dest] that the
3489 socket is not disconnecting and ignore the data if it is.
3490 Affected file silcd/packet_send.c.
3492 * Define inline to __inline on native WIN32 compilation.
3493 Affected file includes/silcwin32.h.
3495 * Added some explicit type casts for inline code since MSVC
3496 require them. Affected files lib/silcutil/silcbuffer.h,
3497 lib/trq/silcdlist.h and lib/trq/silclist.h.
3499 * Print warning in log files from now on if the packet
3500 decryption fails. Affected file silcd/server.c.
3502 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Changed the `say' client operation's interface to accept
3505 new `type' argument to indicate the type of the message sent
3506 by the library. The application may filter the library's
3507 messages according the type. The affected file is the
3508 lib/silcclient/silcapi.h.
3510 * Added two new functions to lib/silcclient/silcapi.h:
3511 silc_client_del_client and silc_client_del_client_by_id.
3512 Affected file lib/silcclient/idlist.c.
3514 * Moved the clientincludes.h from includes/ to silc/ and
3515 serverincludes.h from includes/ to silcd/.
3517 * The modes for the CMODE and CUMODE are now passed as
3518 uint32 for application with COMMAND_REPLY. The affected
3519 file is lib/silcclient/command_reply.c.
3521 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * /WHOIS without arguments shows client's own information.
3524 Affected file lib/silcclient/command.c.
3526 * Changed PING to not accept any arguments. The specs
3527 says that client can ping only the connected server so
3528 requiring an argument is not needed. Affected file is
3529 lib/silcclient/command.c.
3531 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Fixed a fatal bug in private message sending and reception
3534 encryption and decryption when using private message keys.
3535 The implementation was incorrect and did not follow the
3536 specification. It causd that some of the message were
3537 lost since it did not use the sending and receiving keys
3538 as the protocol suggests. This has been fixed and will cause
3539 incompatibilities with older clients when sending private
3540 message encrypted with private message keys. Affected files
3541 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3542 and various other in Irssi SILC Client.
3544 Added `responder' boolean argument to the functions
3545 silc_client_add_private_message_key[_ske] to indicate when
3546 the key is added as responder or initiator of the key
3549 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Removed the silc_ske_check_version function and created
3552 a SilcSKECheckVersion callback. Added also a function
3553 silc_ske_set_callbacks that is now used to set all SKE
3554 callbacks. The callback functions are not given to
3555 the SKE functions anymore, but this function is used to
3558 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3560 * Added `silc_version' argument to the silc_client_alloc
3561 to define the version of the application for the library.
3562 The library will use the version string to compare it
3563 against the remote host's (usually a server) version
3564 string. Affected file lib/silcclient/silcapi.h
3566 * Added the KE protocol context to Key Agreement context
3567 in client library so that we can abort the SKE if it
3568 is in process when we get timeout. Affected file is
3569 lib/silcclient/client_keyagr.c.
3571 * Do not resolve the client ID forever if it returns in the
3572 first time that such client does not exist. This was done
3573 for example with private message. Affected file is
3574 lib/silcclient/client_prvmsg.c.
3576 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Do not add regex.h for WIN32. The affected file
3579 includes/silcincludes.h.
3581 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3582 not work yet 100%. It generates the DLL's automatically
3583 when compiling with --with-win32 under cygwin.
3585 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * lib/contrib/regex.c is not compiled on WIN32.
3589 * Added silc_net_get_socket_opt function to the
3590 lib/silcutil/silcnet.h.
3592 * Added includes/silcwin32.h for WIN32 specific includes
3595 * Do not use ptime structure or any of the posix process
3596 functions on WIN32 in lib/silccrypt/silrng.c.
3598 * Added silc_gettimeofday to provide generic function
3599 for struct timeval on all platforms. Added the function
3600 to lib/silcutil/silcutil.h.
3602 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3604 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3605 library as they clearly belong there. As a plus side we
3606 can make the actual socket connection routines platform
3609 Added also new generic function silc_socket_read and
3610 silc_socket_write (that used to be silc_packet_[read/write].
3611 The implementation of these are platform specific.
3613 * Added WIN32 specific routines of silc_socket_[read/write]
3614 to lib/silcutil/win32/silcwin32sockconn.c.
3616 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3618 * Added preliminary support for native WIN32 compilation under
3619 cygwin (using the -mno-cygwin option for GCC) to the
3620 ./configure.in.pre. The --with-win32 now prepares the
3621 compilation for native WIN32.
3623 * Rewrote the SILC Scheduler interface in the file
3624 lib/silcutil/silcschedule.h. The scheduler is now context
3625 based and does not have anymore any global static scheduler.
3626 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3627 and created lib/silcutil/win32 directory for WIN32 based
3630 * Added Unix specific network routines to the
3631 lib/silcutil/unix/silcunixnet.c and the old
3632 lib/silcutil/silcnet.c includes now only generic routines.
3634 Added WIN32 specific network routines to the
3635 lib/silcutil/win32/silcwin32net.c.
3637 * Added Unix specific utility functions from the
3638 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3640 * Added WIN32 SILC Scheduler to the file
3641 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3644 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3646 * Do not handle JOIN notify in the server if the target client
3647 is not registered (idata->registered == FALSE). The affected
3648 file is silcd/packet_receive.c.
3650 * Update the nickrec->founder in event_cumode in the Irssi SILC
3651 client. Affected file irssi/src/silc/core/silc-channels.c.
3653 * Fixed the CUMODE_CHANGE notify handling in the server when
3654 server and router are announcing their clients on channels.
3655 Now the mode changes are saved and notified correctly. The
3656 affected file is /silcd/packet_receive.c.
3658 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3659 They really did not replace the cache entry in the ID Cache.
3660 Now they do that. Affected file silcd/idlist.c.
3662 * Fixed the KICK notify handling in the Irssi SILC client to
3663 update the channel records so that the kicked client does not
3664 appear to be on the channel. The affected file is
3665 irssi/src/silc/core/silc-channels.c.
3667 * Always update the conn->current_channel when executing command
3668 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3670 * Fixed the KILL notify handling in Irssi SILC client to remove
3671 the killed client on all channels.
3673 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Fixed the silc_parse_command_line to remove extra spaces
3676 from the start and end of the arguments. Affected file is
3677 lib/silcutil/silcutil.c.
3679 * Cancel and free any active protocol in the function
3680 silc_server_close_connection. Affected file silcd/server.c.
3682 * Cancel and free any active protocol in the function
3683 silc_client_close_connction. Affected file is
3684 lib/silcclient/client.c.
3686 * Do not execute the KILL command for clients that are in
3687 history (ie. they are not in the network). Affected file is
3690 * Fixed KILL notify handling, client does not crash anymore.
3691 Affected file irssi/src/silc/core/silc-channels.c.
3693 * Reduced the default packet buffer size from 2048 to 1024 in
3694 lib/silccore/silcpacket.c.
3696 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3697 counter to the SKE context that is incresed when the SKE library
3698 performs async operation outside the library. If the outside
3699 process frees the SKE context and FREED status will be set
3700 and the library will detect after the sync operation that the
3701 libary is freed. The affected files are
3702 lib/silcske/silcske[_status].[ch].
3704 * Resolve the client entry information in the function
3705 silc_client_channel_message to assure that NULL pointer is not
3706 passed as client entry to the application. */
3708 * Fixed the task timeout calculation to assure that there is
3709 never negative timeouts. The affected file is
3710 lib/silcutil/silcschedule.c.
3712 * Fixed the channel user mode notification sending in server.
3713 It was sent point-to-point to the router (or to server by router)
3714 but it needs to be destined to a channel. The routines now
3715 supports sending the channel user mode notifys to the channels
3716 when announcing clients and channels. Affected files are
3717 silcd/server.c and silcd/packet_receive.c.
3719 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3720 It did not actually replace the old channel entry in the cache.
3721 Affected file lib/silcclient/client_notify.c.
3723 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Fixed a possible crash in silc_packet_send_prepare. It now
3726 assures always that there is enough space in the buffer and
3727 at the tail area of the buffer (for MAC).
3729 Fixed the inbound buffer reallocation in silc_packet_read.
3730 It was old code and did not handle the reallocation correctly.
3733 The affected file is lib/silccore/silcpacket.c.
3735 * Fixed buffer overflow in silc_parse_nickname in the file
3736 lib/silcutil/silcutil.c.
3738 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * make install generates new server keys only if there is not
3743 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3746 Added check that if the NOREPLY is set then we will not send
3747 the away message. This avoids infinite loop of away messages
3748 if both clients are away. The affected file is
3749 lib/silcclient/client_prvmsg.c.
3751 * Fixed client crash if /NICK was given without arguments.
3752 Affected file lib/silcclient/command.c.
3754 * Server does not send the invite list in INVITE command back
3755 to the client if the list was not altered. Added this notion
3756 to the protocol spec as well. Affected file silcd/command.c.
3758 Fixed possible crash in INVITE command by checking the
3759 value of silc_server_get_client_route command.
3761 * Fixed the INVITE notify type handling. The arguments are now
3762 taken in correct order and client does not crash. The affected
3763 file is irssi/src/silc/core/silc-channels.c.
3765 Removed the "Inviting xxx to channel" message from the
3766 client library away and let the application handle it.
3767 Affected file lib/silcclient/command.c. Added that message
3768 to Irssi SILC client's message formats.
3770 * Fixed CMODE command crash in client. It now checks the
3771 amount of arguments correctly and does not crash. The affected
3772 file is lib/silcclient/command.c.
3774 * Do not create new channel automatically in silc_channels_join
3775 but check whether the channel by that name already exists.
3776 Affected file irssi/silc/core/silc-channels.c.
3778 * Do not send the SERVER_SIGNOFF to router if the disconnected
3779 entity was the router. Affected file silcd/server.c.
3781 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3782 SILC client as it was missing from there.
3784 Added the handling of the KICK notify to the Irssi SILC client
3785 as it was missing. Added "you have been kicked" message to
3786 Irssi SILC client's message modules formats.
3788 Added the handing of the KILL notify to the Irssi SILC client
3789 as it was missing. Added the kill message module formats
3792 The affected file is irssi/src/silc/core/silc-channels.c.
3794 * The router did not save the channel mode the server announced.
3795 Affected file silcd/packet_receive.c.
3797 * Fixed a possible crash in INFO command in server. If the
3798 server did not provide the server info it crashed. Affected
3799 file silcd/command.c.
3801 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Fixed the GETKEY command in the server to check also the
3804 global list. Otherwise the GETKEY would not work correctly
3805 in normal SILC server. Affected file silcd/command.c.
3807 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Fixed GETKEY crash, it crashed if the command did not succseed.
3811 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3814 is now real and not just an macro interface to GMP.
3816 Removed the entire GMP from the source tree and imported new
3817 NSS MPI library instead. Reason for removing GMP is that it is
3818 extremely large and compiles extremely slow. The NSS MPI
3819 is only a few files and compiles in less than 10 seconds.
3820 The speed is also about the same as GMP. The MPI is imported
3821 to lib/silcmath/mpi.
3823 If the system has GMP installed we will still use the GMP.
3824 If it is not then the NSS MPI will be compiled.
3826 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Merged a long nickname (127 characters long) crash bugfix from
3829 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3831 * Merged a freed memory reference bugfix from Irssi CVS tree.
3832 Affected file irssi/src/core/commands.c.
3834 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added the server's public key sving and verification to the
3837 server when performing the SKE. This was missing and the
3838 remote server's (or router's) public key was accepted without
3839 checking whether we have it previously or trust it at all.
3840 Affected file silcd/protocol.c.
3842 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Check in the silc_server_timeout_remote if protocol is active
3845 and make sure that the protocol's final callback is called so
3846 that all memory if freed. Affected file silcd/server.c.
3848 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * silc_server_whois_send_reply crashed the server if the nickname
3851 was 127 characters long. Affected file silcd/command.c.
3853 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Added sanity check to the silc_server_new_client. If the hostname
3856 is provided inside username then check that the provided hostname
3857 really is the same as the resolved one. If the hostname was not
3858 resolved then check it from the public key. Affected file is
3859 silcd/packet_receive.c.
3861 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3862 if the server disconnected us and the connection is not valid
3863 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3865 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3866 the library to the lib/silcutil/silcutil.[ch].
3868 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Close log file after open. Affected file
3871 lib/silcutil/silclog.c.
3873 * Check whether sock == NULL in silc_client_send_packet and return
3874 if it is. Affected file lib/silcclient/silcclient.c.
3876 * Check rec->entry == NULL in the Irssi SILC Client before
3877 sending the channel message. Affecte file is
3878 irssi/src/silc/core/silc-servers.c.
3880 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Merged a splitted window bugfix from Irssi CVS tree. The
3883 affected file is irssi/src/fe-text/textbuffer-view.c.
3885 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3886 It did not print nickname.
3888 * Improved the distributions system a bit.
3890 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3893 irssi/src/fe-text/gui-window.c.
3895 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3896 to in-active server. The affected file is
3897 irssi/src/silc/core/client_ops.c.
3899 * Resolve the client in USERS command reply if the entry does
3900 not have username resolved. The affected file is
3901 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3902 command to WHOIS command to really resolve stuff. The USERS
3903 is not used any more in any critical section so WHOIS can
3904 be used even though it might be slower than IDENTIFY.
3906 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3909 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Changed the protocol API a bit more consistent in the
3912 lib/silccore/silcprotocol.[ch].
3914 * Changed the following headers to ROBODoc format:
3916 lib/silccore/silcpayload.h
3917 lib/silccore/silcprotocol.h
3918 lib/silccore/silcsockconn.h
3920 All core library headers are now formatted.
3922 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Fixed a bug in Irssi SILC client; do not show that you are
3925 server/router operator if you really are not. Affected file is
3926 irssi/src/silc/core/client_ops.c.
3928 * Renamed silc_command_free_payload to silc_command_payload_free.
3929 Affected file lib/silccore/silccommand.h
3931 * Added silcmath.h to include the prototoypes of various routines
3932 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3935 * Changed the following headers to ROBODoc format:
3937 lib/silccore/silcchannel.h
3938 lib/silccore/silccommand.h
3939 lib/silccore/silcid.h
3940 lib/silccore/silcidcache.h
3941 lib/silccore/silcmode.h
3942 lib/silccore/silcnotify.h
3943 lib/silccore/silcpacket.h
3944 lib/silcmath/silcmath.h
3946 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Added checking to the server code not to start the server if
3949 ciphers and stuff are not configured properly. Affected files
3950 silcd/serverconfig.[h] and silcd/server.c.
3952 * Changed the layout of the header files of the public interfaces
3953 in the SILC libraries. The new layout supports ROBODoc
3954 documentation tool (and some others) so that it is easy to create
3955 a library reference manual. All the other headers and source
3956 code must still follow the CodingStyle document. Also source
3957 code must not include these ROBODoc stuffs, only the headers.
3958 Furthermore, all public interface headers must now be named
3959 by using `silc' prefix, example: silcapi.h, silccipher.h.
3960 Some files were renamed due to this. All the other headers
3961 must not be used as public interfaces. I will update the
3962 CodingStyle document later. Changed following headers, so far:
3964 lib/silcclient/silcapi.h
3965 lib/silccore/silcauth.h
3966 lib/silccore/silcprivate.h
3967 lib/silccrypt/silcdh.h
3969 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Removed silc_client_packet_send_flush from the client library
3974 as it is not needed. Affected file lib/silcclient/client.[ch].
3976 * Added printing of message of unresolved authentication method
3977 to the Irssi SILC client. Added it to the module formats.
3978 Removed the same message from the client library.
3980 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Added new distribution feature, DISTLABEL. Every distribution
3983 can define own preprocessor label that can be used in the
3984 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3985 file distributions, acconfig.h.pre and prepare.
3987 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3989 * Added Makefile.defines_int to include the actual definitions
3990 for Makefile.defines.in. Tested the new distribution system,
3991 created distributions and tested installation.
3993 * Added AWAY message printing to the Irssi SILC client. Added
3994 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3996 * Added SCONNECT command to call the SILC's CONNECT command.
3997 Cannot use CONNECT directly since Irssi uses that internally.
3998 Affected file irssi/src/silc/core/silc-servers.c.
4000 Added ACTION local command. It is same as ME command but takes
4001 the channel as mandatory argument.
4003 Rewrote some of the Irssi's help files to suite for SILC
4006 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Added Makefile.defines[.in] that should for now on be included
4009 in all Makefile.am file in the source tree. That file includes
4010 all common compilation definitions for SILC source tree.
4012 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Minor changes to the ./prepare script to change the package
4015 name according the distribution name to the configure.in.
4017 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4019 * Created new distribution system. Added file `distributions'
4020 that defines all the distributions that can be created out of
4021 the SILC source tree. The ./prepare script now reads that
4022 file to determine how to prepare the distributions. The
4023 first argument to the ./prepare is the name of the distribution
4024 and second is the version of the distribution. If given
4025 without arguments it creates the default (toolkit) distribution
4026 with the default version (defined in ./prepare).
4028 All Makefile.am files that are subject to the distributions
4029 are now named as Makefile.am.pre. These are ./Makefile.am
4030 and lib/Makefile.am. Others may be changed later.
4032 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Added invite list, ban list, some key management and connection
4035 error message printing to module formats in the Irssi SILC client.
4037 * Added new silc_client_set_away_message to set the away message
4038 that is back to the person who sent private message. The
4039 affected file lib/silcclient/silcapi.h and the
4040 lib/silcclient/client_prvmsg.c.
4042 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Fixed the private message sending in the Irssi SILC client,
4045 added local command KEY to the Irssi SILC client.
4047 Added key management and key agreement message formats to the
4048 irssi/src/fe-common/silc/module-formats.[ch].
4050 Added USERS (alias WHO) printing, server/router operator
4051 indication and LIST command printing to the module formats.
4053 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Fixed channel joining notify handling, cumode notify handling
4056 from Irssi SILC client.
4058 * Added SILC specific module-formats to the Irssi SILC client so
4059 that SILC specific message hilighting, colors etc is possible.
4060 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4062 Added channel mode, channel user mode, actions, notices,
4063 whois and whowas printing to the the module-formats.c.
4065 * Fixed a bug in channel deletion in the server. The channel
4066 is not left to the cache even if the channel founder auth mode
4067 is set when there are no users anymore on the channel. Affected
4068 file silcd/server.c.
4070 * The silc_net_localhost now resolves the entire hostname including
4071 the domain name. Affected file lib/silcutil/silcnet.c.
4073 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Changed the ask_passphrase client operation to be ascynchronous.
4076 It has now a completion callback and a context that the
4077 application must call after it has got the passphrase from
4078 the user. Affected files lib/silcclient/silcapi.h,
4079 lib/silcclient/protocol.c, lib/silcclient/command.c and
4082 Added SilcAskPassphrase callback that the application calls
4083 to deliver the passphrase to the library.
4085 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4086 The public key verification and especially a certificate
4087 verification is asynchronous procedure.
4089 Added new SILC_SKE_STATUS_PENDING status to indicate the
4090 request is pending and a callback will be called to finalize
4093 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4094 indicate that remote end did not send its public key (or
4095 certificate), even though we require it. Added check for this
4096 condition in the SKE. This was a security bug, now fixed.
4098 Defined new SilcSKEVerifyCbCompletion callback that is called
4099 when the verification process is completed.
4101 The affected files lib/silcske/silcske_status.h and
4102 lib/silcske/silcske.[ch].
4104 * Changed the verify_public_key client operation to be async
4105 as well. Defined SilcVerifyPublicKey callback that is used to
4106 indicate the success of the public key verification process.
4108 Changed the server and client to use the new async client
4111 * Changed the Irssi SILC client's internal scheduler to be called
4112 twice as many times as it used to be. As a result the client
4113 should be a bit faster now. Affected file is
4114 irssi/src/silc/core/silc-core.c.
4116 * Added support to Irssi SILC client of asynchronous public key
4117 verification and passphrase inquiry. Affected file is
4118 irssi/src/silc/core/silc-core.c.
4120 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Do not say "You have left channel %s" in client library.
4123 Moved it to the application. Affected files are
4124 lib/silcclient/command.c and silc/client_ops.c.
4126 * Fixed silc_client_get_clients. Command context was not
4127 duplicated and was freed memory in the callback. Affected
4128 file lib/silcclient/idlist.c.
4130 * Do not say "you are now talking..." on JOIN command in the
4131 client library. The appliation must handle it.
4133 * Do not say ".. changed topic to" in command reply in the
4134 client libary. The application must handle it.
4136 * Fixed TOPIC command sending in the client library.
4138 * Fixed a memory leak in silc_client_command_free in the file
4139 lib/silcclient/command.c.
4141 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Imported a modified version of Irssi client to the source tree.
4144 The Irssi will be used to create a new client called
4145 Irssi SILC. Imported to irssi/.
4147 Added silc_core_init_finish function to the Irssi. Affected
4148 file irssi/configure.in.
4150 A lot changes in the Makefile.ams around the irssi tree.
4152 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Do not rehash if the new size is same as the old size of the
4155 hash table, in the silc_hash_table_rehash*. The affected file
4156 lib/silcutil/silchashtable.c.
4158 * Replaced hash_table_del_by_context calls from the server
4159 (when channel->user_list and client->channels) to the
4160 hash_table_del as it is sufficient and faster.
4162 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Added silc_hash_table_list, silc_hash_table_get and the
4165 SilcHashTableList structure to provide an alternative way to
4166 traverse the hash table. The affected files are
4167 lib/silcutil/silchashtable.[ch].
4169 * Changed the server's idlist routines to use the hash table
4170 routines to optimize the code.
4172 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Replaced the client entry's `channel' list and channel entry's
4175 `user_list' list to hash tables for optimized lookup. Changed
4176 the code to use the hash table interface around the code.
4177 Affected file lib/silcd/idlist.[ch].
4179 * Added `auto_rehash' boolean argument to the function
4180 silc_hash_table_alloc to indicate whether the hash table should
4181 auto-rehash when it thinks is appropriate time. It will
4182 increase the hash table size if the there is twice as much
4183 entries in the table than the size of the table, and will
4184 decrease the size if there are twice as less entries than
4185 the size of the table.
4187 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4191 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * silc_idcache_purge_by_context deletes the entry now by context
4194 as it is supposed to do. Affected file lib/silccore/idcache.c.
4196 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4197 client is not anymore valid (WHOWAS givens the info) and not
4198 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4200 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Removed the `data' and `data_len' arguments from the ID Cache
4203 interfaces and added `name' argument. ID Cache does not handle
4204 anymore the binary data only a names associated with given ID.
4206 * When hashing a Client ID with silc_hash_id the entire ID is
4207 not hashed anymore, instead only the hash of the Client ID is
4208 hashed. This way we can access the Client ID from the cache
4209 with Client ID but with the hash of the ID (which is a hash of
4210 the nickname) as well without any difference in performance.
4212 Added also silc_idcache_find_by_id_one_ext to do one on one
4213 searching when we have the actual ID. Added also function
4214 silc_hash_client_id_compare. The affected files are
4215 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4217 * When hashing the name associated with a ID it is always done
4218 in lowercase. This way we can access the cache without worrying
4219 about case-sensitivity, even though, for example nicknames are
4222 * Fixed a bug in server with channel message sending. It put
4223 wrong ID type as destination ID. The affected file
4224 silcd/packet_send.c.
4226 * silc_idcache_del_by_context now deletes from all hash tables
4227 by context. Affected file lib/silccore/idcache.c.
4229 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Changed the client library to use the new ID Cache interface.
4232 Changes around the source tree.
4234 * Added silc_hash_table_rehash_ext to rehash with specific
4235 hash function. Affected file lib/silcutil/silchashtable.[ch].
4237 * Added silc_hash_string_compare to compare two strings in the
4238 hash table. Affected file lib/silcutil/silcutil.[ch].
4240 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Added new function silc_idcache_del_by_context into the
4243 lib/silccore/idcache.[ch].
4245 * Changed the server's ID list routines to use the new ID Cache
4246 interface. Changes around the source tree.
4248 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Added silc_hash_table_del[_by_context]_ext functions in to the
4251 lib/silcutil/silchashtable.[ch].
4253 Removed silc_hash_table_find_all* routines and added new
4254 silc_hash_table_find_foreach to replace them.
4256 Added silc_hash_table_replace_ext function as extended
4257 replacing function. Separated the simple hash table interface
4258 from the extended hash table interface in the file
4259 lib/silcutil/silchashtable.h.
4261 * Fixed minor bugs and changed it to use some of the new
4262 hash table functions in lib/silccore/idcache.c
4264 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Added new function silc_hash_table_find_all to return all keys
4267 in the hash table by the specified key. As the hash table is
4268 collision resistant it also makes it possible to have several
4269 duplicate keys in the hash table. This function may be used to
4270 find all of the keys from the hash.
4272 Added user_context arguments to the SilcHashFunction,
4273 SilcHashCompare and SilcHashDestructor to deliver user specified
4276 Added new fuctions silc_hash_table_find[_all]_ext to do
4277 extended lookup with specified hash and compare functions and
4278 specified user contexts.
4280 Added new function silc_hash_table_add_ext to add the key
4281 with specified hash function and user context.
4283 Added new function silc_hash_table_foreach to traverse all
4284 entrys in the hash table. Added SilcHashForeach callback
4287 Added new function silc_hash_table_del_by_context to delete
4288 the entry only if the context associated with the key matches.
4290 Affected files are lib/silcutil/silchashtable.[ch].
4292 * Removed silc_hash_[server/client/channel]_id and added just
4293 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4294 silc_hash_id_compare to compare two ID's using as the hash table
4295 comparison function. Added also silc_hash_data to hash
4296 binary data and silc_hash_data_compare to compare it.
4298 * Removed silc_idlist_find_client_by_hash as it is not needed
4299 anymore. Affected file silcd/idlist.[ch].
4301 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4302 to use internally the SilcHashTable. The new ID Cache is a lot
4303 faster than the old one. Some of the ID Cache interface was also
4304 rewritten and obsolete and stupid functions were removed.
4306 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Added entry_count field to the SilcHashTable to keep the number
4309 of the entries in the table. Implemented the function
4310 silc_hash_table_rehash. Added new function
4311 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4313 Fixed a minor bug in silc_hash_table_free.
4315 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4316 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4317 into the lib/silcutil/silcutil.[ch].
4319 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Implemented a collision resistant hash table into the
4322 lib/silcutil/silchashtable[ch]. See the header and the source
4323 for the SilcHashTable API.
4325 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Merged dotconf version 1.0.2 into lib/dotconf.
4329 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Do not compile anything in lib/silcsim/* if the SIM support
4332 is not enabled. The tree should now compile without problems
4335 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Compiled the SILC under cygwin. Compiled and tested briefly
4338 without problems. More tests needed. The SIMs didn't compile
4341 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4343 * Fixed possible crash in silc_get_username in the
4344 lib/silcutil/silcutil.c.
4346 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Fixed a va_arg in silc/client_ops.c.
4350 * Oops, RC5 routines were named AES and caused some problems
4351 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4353 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Added new SilcIDIP structure into the lib/silccore/id.h and
4356 replaced the old `ip' fields from all SILC ID's to that type.
4357 This is a step towards IPv6 support.
4359 The silc_id_get_len takes now the ID as an extra argument.
4360 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4361 both IPv4 and IPv6 based ID's.
4363 The affected files are lib/silccore/id.[ch] and other files
4364 around the tree using these routines.
4366 * Removed the ID length arguments in server from various
4367 silc_server_send_notify_* routines -> they are not needed
4370 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Fixed memory leak in silc_encode_pem_file in the file
4373 lib/silcutil/silcutil.c.
4375 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Check minor version as well in the SKE. Affected files are
4378 silcd/protocol.c and lib/silcclient/protocol.c.
4380 * Added --identifier option to the server so that an identifier
4381 can be when creating the public key for the server. Affected
4382 file is silcd/silcd.c.
4384 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4385 lib/silccrypt/silcpkcs.c.
4387 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Register default ciphers and stuff when using -C option with
4390 the server. Affected file sildc/silcd.c.
4392 * Put back the servers public key filename format, it is better
4393 than the new one. For now, the client keys are saved with the
4394 new filename format. The affected file silc/client_ops.c.
4396 * Implemented the Cipher API for the rest of the ciphers that
4397 did not implement it or implemented it the wrong way.
4399 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Register default ciphers and stuff when using the -S option
4402 in the client. Affected file silc/silc.c. Same also when
4403 creating new key pair with -C option.
4405 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Fixed the silc_verify_public_key client operation function to
4408 save the public keys differently. The fingerprint is now
4409 used as filename and not the hostname. This way also the
4410 client keys are saved uniquely and not with hostnames. The
4411 affected file is silc/client_ops.c.
4413 * Trimmed the silc_hash_fingerprint function to remove extra
4414 whitespaces from the end of the fingerprint. The affected
4415 file is lib/silccrypt/silchash.c.
4419 * Added silc_cipher_register_default function to register all
4420 default ciphers. It can be used when configuration files
4421 does not exist and the application does not want any specific
4422 ciphers in any specific order.
4424 The SilcDList is now used as silc_cipher_list dynamically
4425 allocated cipher list. Removed the static list all together
4426 and now all ciphers must be allocated to the dynamic list.
4427 The silc_cipher_alloc routine was changed to check only the
4430 All silc_cipher_* routines that used to return int returns
4433 The affected files lib/silccrypt/silccrypt.[ch].
4435 * The same thing was done to silc_hash_* as for silc_cipher_*
4436 routines. Affected files lib/silccrypt/silchash.[ch].
4438 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4439 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4440 Added also silc_pkcs_[un]register[_default] functions.
4441 Removed the data_context from the PKCS API.
4443 * Added silc_hmac_register_default function to register default
4444 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4445 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4446 to unregister all hmacs at once.
4448 * Register the default ciphers, hash functions, PKCSs and HMACs
4449 if client's configuration file does not exist. The affected
4452 * The client did not load the hash functions from the SIM
4453 modules at all. Added support for this. Affected file is
4454 silc/clientconfig.c.
4456 * When decoding public key with silc_pkcs_public_key_decode, check
4457 the supported algorithm only if PKCS are registered. Affected
4458 file lib/silccrypt/silcpkcs.c. The same was done with the
4459 silc_pkcs_private_key_decode.
4461 * Fixed the SILC List routines to keep the list always in order.
4462 It used to change the list's order when traversing the list but
4463 not it preserves the order. Affected file lib/trq/silclist.h.
4465 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Added the client library to use the SilcSocketConnection's
4468 reference counter (by silc_socket_dup) to prevent the bug that
4469 the socket object may be freed underneath async operation.
4471 * The name resolv library checking fixes in the configure.in.pre.
4474 * Created new version of the protocol drafts for future
4475 development. The -03 drafts are the ones that will be changed
4476 in the trunk now and the -02 will remain as they are.
4478 * Send list of CUMODE notifys to the router when announcing
4479 the channel users to the router. Affected file silcd/server.c.
4480 If the router receiving channel founder CUMODE for a channel
4481 that already has channel founder it will send CUMODE notify
4482 to the sender to remove the channel founder rights from the
4483 announced client. Affected file silcd/packet_receive.c.
4485 * The CUMODE notify may now use Server ID as well as the entity
4486 who changes the mode. Updated protocool specs.
4488 * Updated INSTALL and README files.
4490 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * New web pages in the http://silc.pspt.fi. The pages was
4497 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Implemented the [DenyConnectin] config section in the server.
4500 Added silc_server_config_denied_conn to check whether incoming
4501 connection is denied. Affected file silcd/serverconfig.[ch].
4503 * Do not check the ports when checking the incoming configuration
4504 data if the port is 0, meaning any. Affected file is
4505 silcd/serverconfig.c.
4507 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Fixed buffer overflow in silc_string_compare in the file
4510 lib/silcutil/silcutil.c.
4512 * Fixed double free in silc_server_command_leave in the file
4515 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Fixed the version checking in the server. Affected file is
4520 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Fixed the configuration data fetching when accepting new
4523 connections in the server. Affected file silcd/server.c.
4525 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added `sender_entry' argument to the function
4528 silc_server_packet_relay_to_channel so that we can check
4529 whether some destination actually belongs to the same route
4530 the sender belongs (ie, we must not resend the packet to the
4531 sender). Affected file silcd/packet_send.[ch].
4533 * Added `servername' field to the SilcClientEntry in the server
4534 to hold the name of the server where client is from. Affected
4535 file is silcd/idlist.h.
4537 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Moved the channel message encrypting in the router betwen
4540 router connections from silc_server_channel_message to the
4541 silc_server_packet_relay_to_channel since we want to check
4542 whether we have anybody channel before encrypting anything.
4543 Affected files silcd/packet_[receive/send].c.
4545 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Fixed the [AdminConnection] server config section to support
4548 multiple entries. Affected file silcd/serverconfig.c.
4550 * Added support into the server to check the validity of the
4551 incoming connection before executing any KE or authentication
4554 * The connection configuration is now saved to the KE and
4555 connection auth protocol contexts and not fetched anymore in
4556 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4558 * The local hosts listenning address and port is also resolved
4559 now when starting the server. We want to have the socket object
4560 to include the real address and port for the listener. Added
4561 new function silc_net_check_local_by_sock into the files
4562 lib/silcutil/silcnet.[ch].
4564 * Fixed a broadcast bug in server -> do not broadcast if we
4567 * Fixed a routing bug. Do not route broadcast packets ever.
4568 Broadcast packets must be processed always and not routed since
4569 they may be destined to some other host than yourself and thus
4570 would get routed without no good reason. Affected file is
4573 * Added function silc_server_config_is_primary_route to check
4574 whether primary router connection has been configured (a router
4575 configuration that we are initiating). If there is not, we
4576 will assume that there is only two routers in the SILC network
4577 and we will use the incoming router connection as our primary
4578 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4580 * Changed the order of the broadcasting. Broadcast _after_ the
4581 packet has been processed not before. Affected file is
4584 * Fixed a [ClientConnection] parsing bug. The port was never
4585 parsed correctly thus resulting to port 0. Affected file
4586 silcd/serverconfig.c.
4588 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4589 argument and did not set the broadcast packet flag. Affected
4590 file silcd/packet_send.c. Fixed same bug in the function
4591 silc_server_send_notify as well.
4593 * If we receive NEW_ID packet for our own ID in the server, ignore
4596 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Removed the nickname from the Private Message Payload.
4601 Updated the code and the protocol specs.
4603 * Updated protocol specs for submitting to the IETF.
4605 * Tweaked the Random Number Generator a bit. Affected file
4606 lib/silccrypt/silcrng.c. Exported a new function
4607 silc_rng_[global]_add_noise which can be used to add more
4610 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Do not parse packets with different timeout when protocol
4613 is active -> may cause problem with rekey. Affected file
4616 * When server receives signoff notify it must not create
4617 new channel key if the client is on any channels since the
4618 sender of the signoff notify will create it.
4620 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added printing of error messages during SKE protocol from the
4623 failure packet sent by server during SKE. Affected file
4626 * Removed the client's failure_callback handling with timeout
4627 and handle it immediately when received.
4629 * The SKE library returned wrong type in SUCCESS and FAILURE
4630 packets. They must be 32 bit MSB not 16 bit MSB.
4632 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Ok, rewrote the logic of the re-key and now it seems to work.
4635 I tested it on high traffic with frequent re-keys without
4636 problems. Added hmac_receive (and renamed hmac to hmac_send)
4637 in SilcClientConnection in lib/silcclient/client.h and
4638 in SilcIDListData in silcd/idlist.h. Also, removed the
4639 SilcPacketParserContext's cipher and hmac fields as they are
4640 not needed anymore and actually caused some problems when
4641 the ciphers and hmac's changed underneath the packet parser.
4643 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * If re-key protocol is active then process the incoming packets
4646 synchronously since we must assure that icoming packets encrypted
4647 with the old key is processed before the new keys is set to
4648 use. This is true other packets than for REKEY packets.
4649 Affected file silcd/server.c. The same was done to client library
4650 as well, affected file lib/silcclient/client.c.
4652 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Fixed bug in client and server to accept the force send if
4655 the packet is send from silc_[server/client]_packet_process
4656 function. Otherwise the packets are never delivered, oops.
4658 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Disable force sending of packets when REKEY protocol is active.
4661 We must assure that no packet is sent directly when rekey is
4662 performed. All packets must be sent through packet queue.
4663 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4664 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4665 function is silc_[server/client]_packet_send_real to check
4668 * Replaced the SIM paths from example config files to
4669 /usr/local/modules. Also, make install creates now
4670 /usr/local/silc/logs directory to hold all the SILC server
4673 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Made the configure.in.pre work on Solaris. Patch by salo.
4677 * Made all ciphers compatible with non-x86 machines. Defined
4678 CBC mode macros into lib/silccrypt/ciphers_def.h.
4680 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Fixed the make install.
4684 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * When MAC computation fails the silc_packet_decrypt returned 0
4687 even though it was supposed to return -1. Fixed this. The
4688 affected file is lib/silccore/silcpacket.c.
4690 * Do not replace the config files in /etc/silc (in make install)
4691 if they already exist. Affected file ./Makefile.am.
4693 * Do not send re-key packets immediately but through packet queue.
4694 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4696 * Changed silc_net_check_host_by_sock to return FALSE if the
4697 IP/DNS could not be resolved. Though, it returns the IP address
4698 now even if it could not resolve it (but returns also FALSE).
4699 Affected file lib/silcutil/silcnet.[ch].
4701 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added silc_pkcs_decode_identifier to decode the public key's
4704 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4705 Added also silc_pkcs_free_identifier. Added also new context
4706 SilcPublicKeyIdentifier.
4708 * Added -S option to the silc client. It is used to dump the
4709 contents of the specified public key file.
4711 * Changed the PKCS api to return the public key length when
4712 setting the public key.
4714 * Fixed a fatal bug in the public and private key file loading.
4715 Affected file lib/silccrypt/silcpkcs.c.
4717 * Execute the packet parsing for client with zero (0) timeout
4718 if the protocol is active. Affected file silcd/server.c.
4720 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Made the key generation options to the silcd program. Added
4723 -C option, equivalent to client's option.
4725 * Added new [ServerKeys] config section to the server. It
4726 configures the server's public and private key.
4728 * Defined generic Public Key Payload into the protocol
4729 specification to send specific type of public keys and
4732 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4733 public key or certificate.
4735 * Implemented the GETKEY command to the server and to the
4736 client library and on user interface.
4738 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Made preliminary `make install' work.
4742 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added SilcServerRekey context into silcd/idlist.h.
4746 * Added the PFS support as defined in the specification to the
4747 SKE protocol. Affected files lib/silcske/*.c.
4749 * Added `ske_group' field to the SilcServerRekey context to hold
4750 the number of the SKE group that is used with PFS in re-key.
4751 Affected file silcd/idlist.h.
4753 * Added PFS re-key support to the server. Affected file is
4756 * Added silc_protocol_cancel to cancel execution of the next
4757 state of the protocol. Affected file is
4758 lib/silccore/silcprotocol.[ch].
4760 * Added the re-key support with and without PFS to the client
4761 library. Re-key is performed once in an hour, by default.
4763 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4764 Added silc_client_rekey_callback and silc_client_rekey_final.
4765 Affected files are lib/silcclient/protocol.[ch] and
4766 lib/silcclient/client.[ch].
4768 * Removed the `hmac_key' and `hmac_key_len' fields from the
4769 SilcClientConnection structure; not needed. Affected file is
4770 lib/silcclient/client.h.
4774 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Do not ask whether user wants to use the negotiated private key
4777 for private messages, just use it. Affected file is
4778 silc/local_command.c.
4780 * Added `send_enc_key' and `enc_key_len' fields to the
4781 SilcIDListData structure since they are needed in the re-key
4782 phase. Affected file is silcd/idlist.[ch].
4784 * Implemented the simple re-key protocol into the server.
4785 Affected files silcd/server.c and silcd/protocol.[ch]. The
4786 re-key will be performed once in an hour, by default.
4788 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4789 Added silc_server_rekey, silc_server_rekey_callback and
4790 silc_server_rekey_final.
4792 * Removed Tunneled flag from the protocol. Updated the code
4793 and the specifications.
4795 * Adde `pfs' field to the SilcIDListData to indicate whether
4796 the PFS is to be performed in the re-key. Affected file is
4799 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4802 int64 of at least the xintXX size. If void * is less that 4
4803 bytes uint32 * will be used. Defined bool as boolean.
4805 * Changed _ALL_ unsigned long and unsigned int to uint32,
4806 unsgined short to uint16 in the source tree.
4808 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4809 not handle clients that has entry->data.registered == FALSE.
4810 They are not in the network anymore. Affected file is
4813 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Implemented the sending of the SERVER_SIGNOFF notify in the
4816 server. Affected file is silcd/server.c.
4818 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4819 Added also silc_notify_payload_encode_args into the
4820 lib/silccore/silcnotify.[ch].
4822 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4823 Affected file silcd/packet_receive.c.
4825 * Implemented the SERVER_SIGNOFF notify handling in the client
4826 library. Affected file lib/silcclient/client_notify.c. Also,
4827 implemnted the printing of the SERVER_SIGNOFF info to the
4828 application. Affected file silc/client_ops.c.
4830 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4831 if the deleting was successful. Affected file silcd/idlist.[ch].
4833 * Added support for public key authentication in the connection
4834 authentication protocol in the client library. Affected file
4835 lib/silcclient/protocol.c.
4837 * Changed the server's silc_idlist_get_clients_by_* interface
4838 to support already allocated array so that new entries may be
4839 added to pre-allocated array. Affected file silcd/idlist.[ch].
4840 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4841 and command replies.
4843 * All command reply functions in the server now calls the
4844 pending command callback even if error occured. This way the
4845 error will be delivered to the client as well. Affected files
4846 silcd/command.c and silcd/command_reply.c.
4848 * Fixed INFO command to return local server's info if no server
4849 was provided. Affected file lib/silcclient/command.c.
4851 * Removed RESTART command for good. Updated the code and the
4854 * Rewrote parts of the task system. It is a bit simpler now.
4855 Removed unsued task priorities. The affected files are
4856 lib/silcutil/silctask.[ch].
4858 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Moved the USERS printing from the library to the application.
4861 Affected files lib/silcclient/command.c and silc/client_ops.c.
4863 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Added channel key re-key support. The re-key is perfomed
4868 only by the router and is done once in an hour. Added `rekey'
4869 field to the SilcChannelEntry in the server. Affected files
4870 silcd/server.c and silcd/idlist.h.
4872 * Added silc_task_unregister_by_context into the file
4873 lib/silcutil/silctask.[ch].
4875 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Added SILC_UMODE_GONE mode to indicate when the client is not
4878 present in the SILC network. Added also support to the local
4879 command AWAY that will set this mode. Added support of showing
4880 "xxx is gone" in WHOIS command. The USERS command shows the
4881 gone status as well.
4883 * Fixed setting server and router operator privileges in the
4884 server's UMODE command. Affected file silcd/command.c.
4886 * Merged the SKE KE1 and KE2 payloads into one payload. The
4887 new KE payload is equivalent to the old KE2 payload.
4889 Cleaned up the SKE Start Payload parsing. It now uses the
4890 simple buffer unformatting to do the parsing. A lot faster
4893 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4894 to the SKE that is used to indicate whether both of the SKE
4895 parties should perform authentication. By default only the
4896 responder performs authentication. By setting this flag also
4897 the initiator must do authentication. By default it is unset
4898 since in normal SKE case, client to server connection, only
4899 the responder should do authentication. When doing SKE between
4900 two clients both should perform authentication. Updated the
4901 code and the protocol specs.
4903 * A little fix to IDENTIFY command in the server. Search the
4904 client first by hash not nickname. Affected file is
4907 * Fixed the silc_client_close_connection to support closing
4908 the client to client connections wihtout deleting too much
4909 data. Affected file lib/silcclient/client.c.
4911 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4912 are received if protocol used to be active but is not anymore
4913 the application would crash due to NULL pointer dereference.
4914 Affected files silcd/server.c and lib/silcclient/client.c.
4916 * Added `hash' field to the SilcClientConnection to include
4917 the hash function negotiated in the SKE protocol.
4919 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4920 to set the channel founder authentication data. A client can
4921 claim the founder rights later by providing the authentication
4922 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4923 This way the channel founder can regain the channel founder
4924 privileges even it is left the channel. This works only on
4925 local server and the client must be connected to the same
4926 server to be able to regain the founder rights. Updated the
4927 protocol specs accordingly.
4929 Added support to the CMODE command in the client to set the
4930 founder auth data. Read the README to see how to set it.
4932 Added support to the CUMODE command to claim the founder
4933 rights. Read the README to see how to do it.
4935 Added support for the founder authentication to the Channel
4936 Entry in the server. Affected file silcd/idlist.h.
4938 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4939 server's CMODE command. Affected file silcd/command.c.
4941 * Added the following new functions into lib/silccore/silcauth.[ch]:
4942 silc_auth_get_method and silc_auth_get_data.
4944 * The server now saves the remote hosts public key to the
4945 SilcIDListData pointer. Affected file silcd/protocol.c.
4947 * The normal server now does not remove the channel entry from
4948 the cache if the founder authentication data is set. It used
4949 to remove it if the founder was the last one on the channel on
4950 the server and left the channel. The auth data is saved and
4951 if the channel is re-joined later the old entry is used with
4952 the old auth data. Affected files silcd/command_reply.c and
4955 * Removed the `pkcs' field from the SilcIDListData structure
4956 in the server; it is not used. Affected file silcd/idlist.h.
4958 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Fixed packet processing on slow links. Partial packets were
4961 never re-processed because the incoming data buffer was cleared
4962 by the application. Application must not directly clear the
4963 sock->inbuf, the packet processing routines handle it. Fixed
4964 this in client library and in server.
4966 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Fixed the WHOIS and IDENTIFY send reply function to really
4969 check whether to send list or just one entry. Affected file
4972 * Cleaned up the LEAVE command's channel key distribution. The
4973 affected file silcd/command.c.
4975 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4976 can enforce the channel mode as well. In that case the ID
4977 includes the ID of the server. The code now enforces the
4978 mode change if the router have different mode than the server.
4980 * The notify client operation with CMODE_CHANGE notify can now
4981 return NULL client_entry pointer if the CMODE was not changed
4982 by client. Application must check for this.
4984 * Added <Server ID> argument to INFO command to support server
4985 info fetching by Server ID.
4987 * Added silc_server_announce_get_channel_users to get assembled
4988 packets of channel users of the specified channel. Affected
4989 file silcd/server.[ch].
4991 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4992 was freed underneath the ID Cache.
4994 * Re-announce clients when the server received CHANNEL_CHANGE
4995 notify from the router. Affected file silcd/packet_send.c.
4997 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5000 crashed since it did not handle the fact that there is no cipher
5001 called "3" and didn't check the error condition. Now fixed.
5003 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5004 flag. It can be used to send message requests.
5006 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Implemented the RESTART command in the client.
5010 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5011 notice type messages. Added notice printing to the user
5014 * The channel keys are not re-generated if the channel's mode
5015 is PRIVKEY, ie private key on the channel exists. Affected
5016 files silcd/server.c and silcd/command.c.
5018 * Fixed a little bug in channel message delivery when channel
5019 private keys are set in the server. Affected file is
5020 silcd/packet_send.c.
5022 * Changed the setting on channel->on_channel = TRUE from the
5023 silc_client_save_channel_key to the JOIN command reply. The
5024 key payload is not received if the private channel key is set.
5025 Affected file lib/silcclient/command_reply.c and the
5026 lib/silcclient/client_channel.c.
5028 * When the CMODE_CHANGE notify is sent and the channel private
5029 key mode is removed the channel key must be re-generated in
5030 other cells as well. Added this support for the router in the
5031 silcd/packet_receive.c.
5033 * Added new local command NOTICE to send notice message on
5034 channel. Affected file silc/local_command.[ch].
5036 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added new local command ME to the client. It is used to send
5039 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5040 some action. Affected file silc/local_command.[ch].
5042 * Changed channel_message and private_message client operations
5043 to deliver the message flags to the application. Added also
5044 the `flags' arguments to the silc_client_send_channel_message
5045 and silc_client_send_private_message functions. Affected file
5048 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Redefined the Private Message Payload to support private message
5051 keys and to support the new private message flags. Updated
5052 the protocol specs. Flags makes it possible to have for example
5053 CTCP style messages.
5055 * Added new type SilcPrivateMessagePayload and defined an API
5056 for it in the lib/silcclient/silcprivate.[ch].
5058 * Tested private message private keys successfully. Tested the
5059 private message key set, unset and list commands with the new
5062 * Redefined the Channel Message Payload to include the channel
5063 message flags (equal with private message flags) to support
5064 for example CTCP style messages.
5066 * Defined some of the message (for channel and private message)
5067 flags. Updated the protocol specs and added the flags to the
5068 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5070 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Added SilcKeyAgreementStatus type to the key agreement routines
5073 to indicate the current status and error if one occured.
5074 The status types are defined in the lib/silcclient/silcapi.h.
5076 * Added new local command KEY that is used to set and unset private
5077 keys for channels, set and unset private keys for private messages
5078 with remote clients and to send key agreement requests and
5079 negotiate the key agreement protocol with remote client. The
5080 key agreement is supported only to negotiate private message keys,
5081 it currently cannot be used to negotiate private keys for channels,
5082 as it is not convenient for that purpose.
5084 * Fixed a minor pending callback setting bug in the function
5085 silc_client_get_client_by_id_resolve, now the function works.
5086 Affected file lib/silcclient/idlist.c.
5088 * Added function silc_net_get_local_port to get local bound
5089 port by socket. Added to lib/silcutil/silcnet.[ch].
5091 * Added `sockets' and `sockets_count' fields to the SilcClient
5092 object. They hold the sockets of the listenning sockets in
5093 the client. Listenning sockets may be for example the key
5094 agreement server. Affected file lib/silcclient/client.[ch].
5095 Added functions the silc_client_add_socket and the
5096 silc_client_del_socket. They are exported to the application
5099 * Added ~./silc/clientkeys to support other client's public keys.
5101 * Renamed verify_server_key client operation to verify_public_key
5102 and added one argument to indicate the type of the connection
5103 (server, client etc.).
5105 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Added silc_server_connection_auth_request to handle the
5108 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5109 silcd/packet_receive.[ch].
5111 * Added silc_server_send_connection_auth_request into the
5112 silcd/packet_send.c to send the connection auth request packet.
5114 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5117 * Fixed the public key authentication in responder side in the
5118 server. The `auth_data' pointer includes the SilcPublicKey
5119 not the path to the public key. Affected file silcd/protocol.c.
5121 * Implemented the public key authentication in the initiator side
5122 in the server. Affected file silcd/protocol.c.
5124 * Removed the [RedirectClient] config section from the server
5125 configuration. Is not needed and I don't want to implement it.
5127 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Cleaned up the CMODE command in the server. It now works
5130 correctly and supports all the modes defined in the protocol.
5131 Affected file is silcd/command.c.
5133 * Added `hmac_name' field to the SilcChannelEntry in the server
5134 to hold the default HMAC of the channel. It can be set when
5135 creating the channel (with JOIN command). Affected files
5138 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5139 type to indicate the change of the current cipher and hmac
5140 on the channel. Client can safely ignore the <cipher> argument
5141 (if it chooses to do so) since the CHANNEL_KEY packet will
5142 force the channel key change anyway. The <hmac> argument is
5143 important since the client is responsible of setting the new
5144 HMAC and the hmac key into use.
5146 * Fixed the CMODE command in the client library as well.
5148 * Tested CMODE command in router environment successfully.
5150 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Show the version of the remote client (or server) when connecting
5153 to the server. It is logged to the log file. Affected file
5154 is silcd/protocol.c.
5156 * Fixed the KILLED notify handling in the client library. The
5157 client must be removed from all channels when receiving the
5160 Also, do not remove the client entry when giving the KILL
5161 command but when the KILLED notify is received.
5163 * Removed silc_idlist_find_client_by_nickname from the server.
5164 Not needed anymore. Affected files silcd/idlist.[ch].
5166 * Implemented the CHANNEL_CHANGE notify type handling to the
5167 server. Affected file silcd/server.c.
5171 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Added silc_server_send_notify_invite to send the INVITE
5174 notify between routers.
5176 * Implemented the INVITE command correctly to the server.
5178 * Implemented the INVITE notify type handling in the server.
5180 * Implemented the INVITE command to the client library and on the
5183 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Added function silc_server_get_client_resolve to find the
5186 client entry by ID from all ID lists and then resolve it
5187 (using WHOIS) if it cannot be found. Affected file is
5190 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Implemented the BAN command to the client library.
5194 * The JOIN command in the server now checks the invite list
5197 * Changed the silc_command_reply_payload_encode_va and the
5198 silc_command_payload_encode_va to support that if argument is
5199 NULL it ignores and checks the next argument. Affected file
5200 lib/silccore/silccommand.c.
5202 * Added silc_server_send_notify_ban to send the BAN notify
5203 type between routers.
5205 * Chaned the silc_notify_payload_encode to support that if
5206 argument is NULL it ignores and checks the next argument.
5207 Affected file lib/silccore/silcnotify.c.
5209 * Tested ban lists in router environment successfully.
5211 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Implemented BAN command to the server, in silcd/command.[ch].
5215 * Removed the BAN and INVITE_LIST modes from the CMODE command
5218 * Added function silc_string_match to regex match two strings.
5219 Affected files lib/silcutil/silcutil.[ch].
5221 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Redefined parts of the SilcChannelEntry in the server to support
5224 the new ban and invite lists.
5226 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Redefined the INVITE command. The same command can be used to
5229 invite individuals to the channel but also to manage the invite
5230 list of the channel (to add to and remove from the invite list).
5231 Updated the protocol specs.
5233 * Added new command SILC_COMMAND_BAN that can be used to manage
5234 the ban list of the channel. Updated the protocol specs.
5236 * Removed the channel modes: the SILC_CMODE_BAN and the
5237 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5238 in the CMODE command. The equivalent features are now available
5239 using INVITE and BAN commands. Updated the protocol specs.
5241 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5242 in the network about change in the current ban list. The notify
5243 type is not used by the client.
5245 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5246 support the invite lists.
5248 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Added new function silc_string_regexify that converts string
5251 including wildcard characters into regex string that can
5252 be used by the GNU regex library. Added into the file
5253 lib/silcutil/silcutil.[ch].
5255 Added silc_string_regex_combine to combine to regex strings
5256 into one so that they can be used as one regex string by
5257 the GNU regex library. Added into the file
5258 lib/silcutil/silcutil.[ch].
5260 Added silc_string_regex_match to match two strings. It returns
5261 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5263 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Imported GNU regex to the soruce tree into lib/contrib.
5266 Fixed some compiler warning from the regex.c.
5268 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Fixed MOTD command in the server to work in router environment.
5272 * Fixed the MOTD command in the client library to support
5273 the server argument in the command.
5275 * Added `nickname_len' argument to the silc_idlist_add_client
5276 in the server, as the `nickname' argument may be binary data
5279 * Added silc_idlist_get_channels to return all channels from
5282 * Implemented LIST command to the server. Affected file is
5285 * Implemented the LIST command to the client library and on the
5288 * Added [<user count>] argument to the LIST command reply.
5289 With private channels the user count is not shown.
5291 * Updated TODO and README.
5293 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * The client entry's data.registered must be TRUE even with
5296 global client entry on global client list. The data.registered
5297 is used to check whether the client is anymore in the network,
5298 for example with WHOWAS command so it must be valid.
5300 * Fixed the WHOWAS command in the server. It now actually works
5301 in router environment. Added function into silcd/command_reply.c
5302 silc_server_command_reply_whowas_save.
5304 * Added silc_idlist_purge function to the silcd/idlist.c
5305 to periodically purge the ID Cache.
5307 * Fixed INFO command in the server. It works now in router
5308 environment. Added <server name> argument to the INFO command
5309 reply. Updated the protocol specs.
5311 * Fixed minor bug in silc_idcache_purge to not purge if the
5312 expire value is zero.
5314 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5315 they were buggy because of the WHOWAS information.
5317 * Fixed local command MSG to handle the async resolving of
5318 the remote client properly. It used to fail the first MSG.
5319 Affected file silc/local_command.c.
5321 * Added `data_len' field to SilcIDCache context.
5323 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Update TODO. Todo in commands in the server.
5327 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5330 used by routers as broadcast packet to inform other routers
5331 about the changed user mode.
5333 Implemented the notify handling in the server. Affected file is
5334 silcd/packet_receive.c. Added the function
5335 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5337 * Added new generic Channel Payload and deprecated the New Channel
5338 Payload. The New Channel Payload is now the generic Channel
5341 * Added new argument `mode' to the silc_server_send_new_channel
5342 as it is required in the Channel Payload now.
5344 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5345 and created a new and real SilChannelPayload to represent the
5346 new generic Channel Payload. Implemented the encode/decode
5347 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5349 * Added silc_server_get_client_channel_list to return the list
5350 of channels the client has joined for WHOIS command reply.
5351 Affected file silcd/server.[ch].
5353 * Implemented the channel list sending in the WHOIS command reply
5354 in server and in the client.
5356 Implemented the channel list displaying on the user interface
5357 as well. Affected file silc/client_ops.c.
5359 * Added silc_channel_payload_parse_list to parse list of Channel
5360 Payloads. It returns SilcDList list of SilcChannelPayloads.
5361 Client for example can use this function to parse the list of
5362 channels it receives in the WHOIS command reply. The caller
5363 must free the list by calling silc_channel_payload_list_free.
5364 Affected files lib/silccore/silcchannel.[ch].
5366 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Added one new argument <user mode> to the WHOIS command reply
5369 to return the mode of the user in SILC. Updated the protocol
5372 Implemented it to the server and client.
5374 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Fixed the mode printing on the user interface on joining.
5377 Affected file silc/client_ops.c.
5379 * Implemented the UMODE command and user modes in general to the
5380 client library and to the user interface.
5382 * Implemented the UMODE command to the server.
5384 * The server now sends UNKNOWN_COMMAND error status if client sends
5385 unknown command. Affected file silcd/command.c.
5387 * All server commands now handle the command identifier the right
5388 way when sending the command reply to the client. The client can
5389 use to identify the command replies with the identifier.
5391 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Added silc_server_get_client_route to resolve the route to
5394 the client indicated by the client ID. Affected file is
5397 * Added silc_server_relay_packet as general function to relay
5398 packet to arbitrary destination. This deprecates functions
5399 like _send_private_message_key, _relay_notify etc. Affected
5400 file is silcd/packet_send.[ch].
5402 Removed silc_server_send_key_agreement,
5403 silc_server_send_private_message_key and
5404 silc_server_packet_relay_notify functions from the file
5405 silcd/packet_send.[ch].
5409 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5410 server. Affected file silcd/packet_receive.[ch].
5412 * Implemented the KILL command to the client. Implemented the
5413 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5414 Affected files lib/silcclient/command[_reply].c and
5415 lib/silcclient/client_notify.c. Implemented the KILL notify
5416 printing in the user inteface.
5418 * Fixed a lot silc_parse_nick memory leaks from the client
5419 library in the file lib/silcclient/command.c.
5421 * Changed the silc_server_send_notify_on_channels's `sender'
5422 argument from SilcSocketConnection to SilcClientEntry to
5423 check the sender as entry and not as connection object and not
5424 to send to the client provided as argument. The affected file
5425 is silcd/packet_send.[ch].
5427 * The notify packets that are destined directly to the client used
5428 to not to be processed by the server. Now changed that and the
5429 server processes all notify packets. After relaying the packet
5430 to the client the notify packet is processed in the server.
5432 * The silc_server_free_client_data now checks whether there is
5433 pending outgoing traffic for the client and purges the data to
5434 the network before removing the client entry.
5436 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5439 an client is killed from the SILC Network. Updated the protocol
5442 Added new function silc_server_send_notify_killed to the
5443 silcd/packet_send.[ch].
5445 * Added function silc_server_packet_relay_notify to relay notify
5446 packets that are destined directly to a client. In this case
5447 the server does not process the notify packets but merely relays
5448 it to the client. Affected file silcd/packet_send.[ch].
5450 Added also silc_server_packet_process_relay_notify to check
5451 whereto relay the notify. Affected file is
5452 silcd/packet_receive.[ch].
5454 * Implemented the KILL command to the server.
5458 * Added the backup schema desgined last fall to the protocol
5459 specs for everyone to see. The specification is in the
5460 *-spec-xx.txt draft and the packet type definitions for the
5461 backup routers is in *-pp-xx.txt draft. Thusly, added also
5462 new packet type SILC_PACKET_CELL_ROUTERS.
5464 * A big security problem in the implementation discovered. The
5465 signoff of an client did not cause new channel key generation
5466 which it of course should've done. The channel keys must be
5467 always re-generated when client leaves (or signoffs) the channel.
5468 The silc_server_remove_from_channels funtion now handles
5469 the channel key re-generation.
5471 * Added `sender' argument to the silc_server_send_notify_on_channels
5472 to not to send the client provided as argument. Affected file
5473 silcd/packet_send.[ch].
5475 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Implemented OPER and SILCOPER commands into the server and
5480 * Added silc_auth_verify and silc_auth_verify_data to verify
5481 the authentication directly from the authentication payload.
5482 It supports verifying both passphrase and public key based
5483 authentication. Affected file lib/silccore/silcauth.[ch].
5485 * Added `hash' field to the SilcIDListData structure. It is the
5486 hash negotiated in the SKE protocol. Affected file is
5489 * Slight redesigning of the SilcAuthPayload handling routines.
5490 Do not send SilcPKCS but SilcPublicKey as argument.
5492 * Implemented the public key authentication support to the
5493 serverconfig. The public key is loaded from the provided path
5494 and saved as authentication data to void * pointer. Thus,
5495 changed the unsigned char *auth_data to void *auth_data;
5497 * Fixed SHUTDOWN command to send the reply before the server
5498 is shutdown. :) Affected file silcd/command.c.
5500 * Fixed fatal bug in CONNECT command. The hostname was invalid
5501 memory and server crashed. Affected file silcd/command.c.
5503 * Fixed fatal bug in CLOSE command. The server_entry became
5504 invalid but was referenced later in the command. Affected file
5507 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Fixed fatal bug in failure packet handling. Server ignored
5510 the failure and thus crashed when it came.
5514 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5517 that the command may be executed only once in (about) 2 seconds.
5518 The old SILC_CF_LAG flag is same but allows command bursts up
5519 to five before limiting.
5521 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5522 server code. Various commands now includes the CF_LAG_STRICT
5523 flag to disallow any kind of miss-use of the command.
5525 * Fixed the silc_buffer_unformat to not to allocate any data
5526 if the length of the data is zero. It used to allocate the
5527 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5529 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Changed the format of AdminConnection configuration section
5532 in the server. Added username of the admin to the format.
5533 Affected files silcd/serverconfig.[ch].
5535 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5536 to return admin configuration data by host, username and/or
5539 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Implemented WHOWAS command to the server. Added the functions:
5543 silc_server_command_whowas_parse,
5544 silc_server_command_whowas_send_reply,
5545 silc_server_command_whowas_from_client and
5546 silc_server_command_whowas_from_server
5548 * Added <Client ID> argument to the WHOWAS command reply. Updated
5549 the protocol specs accordingly.
5551 * Implemented WHOWAS command and command_reply to the client
5554 Implemented the WHOWAS printing on the user interface.
5556 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Added new argument to the WHOWAS command reply, the real name.
5559 It is an optional argument. Updated the protocol specs.
5561 * Added SilcIDCacheDestructor callback that is registered when
5562 the SilcIDCache is allocated. The callback is called when
5563 an cache entry in the ID Cache expires, or is purged from the
5564 cache. Added into lib/silccore/idcache.[ch].
5566 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5567 to destruct the client entries when the cache entry expires.
5568 Other ID Cache's in server and in the client library ignores
5571 * If the ID Cache entry's `expire' field is zero then the entry
5572 never expires. Added boolean `expire' argument to the
5573 silc_idcache_add function in the lib/silccore/idcache.[ch].
5574 If it is TRUE the default expiry value is used.
5576 * Added silc_server_free_client_data_timeout that is registered
5577 when client disconnects. By default for 5 minutes we preserve
5578 the client entry for history - for WHOWAS command.
5580 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Added support to the server to enforce that commands are not
5583 executed more than once in 2 seconds. If server receives
5584 commands from client more frequently, timeout is registered
5585 to process the commands. Affected file silcd/command.c.
5586 Added new function silc_server_command_process_timeout.
5588 * Changed NICK_NOTIFY handling in client library to check that
5589 if the client's nickname was changed, so there is no need to
5590 resolve anything from the server.
5592 * Removed error printing from the WHOIS and IDENTIFY commands.
5593 If error occurs then it is ignored silently in the client library.
5594 The application, however, may map the received error to
5595 human readable error string. The application currently maps
5596 the NO_SUCH_NICKNAME error to string.
5598 * Made the command status message public to the application. Moved
5599 them from lib/silcclient/command_reply.c to
5600 lib/silcclient/command_reply.h. The application can map the
5601 received command status to the string with the
5602 silc_client_command_status_message function.
5604 * Added check to the server to check that client's ID is same
5605 as the Source ID in the packet the client sent. They must
5608 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Added dist-bzip hook to the Makefile.am to make bzip2
5611 compressed distributions.
5613 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * Server now enforces the maximum length for the nickname and
5616 the channel as protocol specification dictates. 128 bytes for
5617 nickname and 256 bytes for channel name.
5619 * Moved the WHOIS printing to the application. The client libary
5620 does not print out the WHOIS information anymore, the application
5621 must do it. Renamed silc_client_command_reply_whois_print to
5622 the silc_client_command_reply_whois_save.
5624 The client's idle time is also sent to the application now, and
5625 the idle is shown on screen.
5627 * Added silc_client_command_reply_identify_save to save the
5628 received IDENTIFY entries.
5630 * Do not check for channel private keys in message sending and
5631 reception if the channel does not have the PRIVKEY mode set.
5632 Affected file lib/silclient/client_channel.c.
5634 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5637 just surfaced after chaning the JOIN procedure.
5639 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Added silc_client_get_clients_by_list to get client entries
5642 from Client ID list, that is returned for example by JOIN
5643 and USERS command replies. The application should use this
5644 function for example when JOIN command reply is received to
5645 resolve the clients already on the channel (library does not
5646 do that anymore as USERS command reply is not used in the JOIN
5647 procedure anymore). Affected files lib/silcclient/silcapi.h and
5648 lib/silcclient/idlist.c.
5650 * JOIN command reply and USERS command reply returns now SilcBuffer
5651 pointers instead of unsigned char pointers when returning
5652 the client list and mode list.
5654 * Added <Client ID> argument to the JOIN command reply, mainly
5655 for the server to identify for which client the command was
5656 originally sent. Updated protocol specs accordingly.
5658 * Added SilcDlist private_key pointer to the SilcChannelEntry
5659 in the client to support the channel private keys. Affected
5660 file is lib/silcclient/idlist.h.
5662 * Added SilcChannelPrivateKey argument to the function
5663 silc_client_send_channel_message so that application can choose
5664 to use specific private ke if it wants to. If it is not provided,
5665 the normal channel key is used, unless private keys are set.
5666 In this case the first (key that was added first) is used
5667 as the encryption key.
5669 * Implemented the support for channel private key handling.
5670 Implemented the following functions:
5672 silc_client_add_channel_private_key,
5673 silc_client_del_channel_private_keys,
5674 silc_client_del_channel_private_key,
5675 silc_client_list_channel_private_keys and
5676 silc_client_free_channel_private_keys
5678 Affected file lib/silcclient/client_channel.c.
5680 * Added the support for the private keys in the channel message
5681 sending and encryption and in the message reception and
5682 decryption. Affected funtions are
5683 silc_client_send_channel_message and silc_client_channel_message.
5685 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added SKE's key verify callback to the client library's
5688 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5690 * Removed the statement that server (or router) must send USERS
5691 command reply when joining to the channel so that the client
5692 knows who are on the channel. Instead, the client list and
5693 client's mode list is now sent in the JOIN command reply to the
5694 client who joined channel. This is better solution.
5696 * Added function silc_server_get_users_on_channel and function
5697 silc_server_save_users_on_channel to the silcd/server.[ch].
5699 * Removed function silc_server_command_send_users from the
5702 * Do not show topic on the client library anymore. The topic is
5703 sent in the command reply notify to the application and the
5704 application must show the topic now.
5706 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added client searching by nickname hash into the IDENTIFY and
5709 WHOIS commands in the server as they were clearly missing from
5710 them. Affected file is silcd/command.c.
5712 * Fixed a bug in private message receiving in the client library.
5713 The remote ID was freed and it wasn't supposed, now it is
5716 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Minor fix to the channel payload; allocate the data area, as it
5719 needs to be of specific length.
5721 * If the key agreement port is zero then the operating
5722 system will define the bound port. Affected files are
5723 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5725 * Added new function silc_channel_payload_decrypt into the file
5726 lib/silccore/silcchannel.[ch].
5728 * Moved the channel message etc, check from silc_packet_decrypt
5729 to applications. The library calls now a generic
5730 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5731 when the packet is either normal or special. This was done to
5732 allow more wide range of checking that was not allowed when
5733 the code was in library. Now applications can do virtually any
5734 checks to the packet and return to the library the decision how
5735 the packet should be processed. Affected files are
5736 lib/silccore/silcpacket.[ch].
5738 Added silc_server_packet_decrypt_check to the server and
5739 silc_client_packet_decrypt_check to the client library.
5741 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5742 to send with specified source and destination information.
5744 * Channel message delivery between routers was broken after the
5745 channel key distribution was fixed earlier. The channel key
5746 was used be to distributed to other routers as well which is not
5747 allowed by the protocol. Now this is fixed and channel keys
5748 really are cell specific and the channel message delivery between
5749 routers comply with the protocol specification.
5751 * Fixed various commands in server to check also the global list
5752 for the channel entry and not just the local list. The affected
5753 file silcd/command.c.
5755 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Added assert()s to buffer formatting and unformatting routines
5758 to assert (if --enable-debug) when error occurs. Affected
5759 file: lib/silcutil/silcbuffmt.c.
5761 * Changed to auto-reconnect to check whether the remote host is
5762 router and register the re-connect timeout if it is. It used
5763 to check that whether we are normal server, but router must do
5764 auto-reconnect with another router as well. Affected file
5767 * Removed the [<key len>] option from CMODE command as the cipher
5768 name decides the key length, nowadays. See the defined ciphers
5769 from the protocol specification.
5771 * Added [<hmac>] option to the CMODE command to define the HMAC
5772 for the channel. Added SILC_CMODE_HMAC channel mode.
5774 * Added [<hmac>] option for the JOIN command so that user can
5775 select which HMAC is used to compute the MACs of the channel
5778 * Added Hmac field to the Channel Message Payload. The integrity
5779 of plaintext channel messages are now protected by computing
5780 MAC of the message and attaching the MAC to the payload. The
5781 MAC is encrypted. Now, it is clear that this causes some
5782 overhead to the size of the packet but rationale for this is that
5783 now the receiver can verify whether the channel message decrypted
5784 correctly and also when private keys are set for the channel the
5785 receiver can decrypt the packet with several keys and check from
5786 the MAC which key decrypted the message correctly.
5788 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5789 lib/silccrypt/silccipher.[ch].
5791 * Added silc_hash_len to return the digest length into the
5792 lib/silcrypt/silchash.[ch].
5794 * Rewrote parts of Silc Channel Payload interface in the
5795 lib/silccore/silcchannel.[ch]. The encode function now also
5796 encrypts the packet and parse function decrypts it.
5798 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Fixed a minor formatting bug in the SKE's key material processing.
5801 It actually might have processed the keys wrong way resulting
5804 * Redefined the mandatory HMAC algorithms and added new algorithms.
5805 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5806 and hmac-md5 truncated to 96 bits. The mandatory is now
5807 hmac-sha1-96. Rest are optional (including the one that used
5808 to be mandatory). Rationale for this is that the truncated HMAC
5809 length is sufficient from security point of view and can actually
5810 make the attack against the HMAC harder. Also, the truncated
5811 HMAC causes less overhead to the packets. See the RFC2104 for
5814 * Added new [hmac] configuration section. The SKE used to use
5815 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5816 is of course wrong. The official names that must be proposed in
5817 the SKE are the ones defined in the protocol specification
5818 (hmac-sha1-96 for example). The user can configure any hmac
5819 using any hash function configured in the [hash] section. At
5820 least, the mandatory must be configured.
5822 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5824 * Added HMAC list to the SKE proposal list. It has now both
5825 hash algorithm list and HMAC list. This makes the protocol
5826 incompatible with previous versions. The SKE now seems to work
5827 the way it is supposed to work, for the first time actually.
5829 * Defined plain Hash algorithms to the protocol specification.
5832 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Implemented support for key agreement packets into the server.
5835 Added functions silc_server_key_agreement and
5836 silc_server_send_key_agreement. Other than these functions,
5837 server has nothing to do with this packet.
5839 * Added support for private message key packets into the server.
5840 Added functions silc_server_private_message_key and
5841 silc_server_send_private_message_key.
5845 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5846 called in the protocol's final callback instead in the END
5847 protocol state. This makes a little more sense and in the same
5848 time in client we can use the same protocol routines for normal
5849 key exchange and to key agreement packet handling as well.
5851 * Added to both client's and server's KE protocol context the
5852 SilcSKEKeyMaterial pointer to save the key material. We will
5853 bring the key material to the protocol's final callback by doing
5854 this. The final callback must free the key material.
5856 * Added SKE's packet_send callback into client's KE protocol
5857 context so that the caller can choose what packet sending function
5858 is used. This way we can use different packet sending when
5859 doing normal SKE when doing key agreement packet handling (in
5860 the key agreement packet handling we do not want to encrypt
5863 * Implemented the responder side of the key agreement routines
5864 in the client. The client can now bind to specified port and
5865 accept incoming key negotiation. The key material is passed
5866 to the application after the protocol is over.
5868 * Implemented the processing of incoming Key Agreement packet
5869 in the client. Added function silc_client_key_agreement to
5872 * Implemented the intiator side of the key agreement routines
5873 in the client. The client can now initiate key agreement with
5874 another remote client. The key material is passed to the
5875 application after the protocol is over.
5877 * Created client_keyagr.c to include all the key agreement
5880 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5881 SILC_TASK_CALLBACK except that it is not static.
5883 * Created client_notify.c and moved the Notify packet handling
5884 from the client.[ch] into that file.
5886 * Created client_prvmsg.c and moved all private message and
5887 private message key routines from the client.[ch] into that file.
5889 * Create client_channel.c and moved all channel message and
5890 channel private key routines from the client.[ch] into that file.
5892 * Changed silc_client_get_client_by_id_resolve to resolve with
5893 WHOIS command instead of IDENTIFY command, in the file
5894 lib/silclient/idlist.c.
5896 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Implemented the SKE's responder side to the Client library.
5900 * When FAILURE is received to the protocol do not trust it
5901 blindly. Register a timeout to wait whether the remote closes
5902 the connection as it should do it, only after that process the
5903 actual failure. This was changed to both client and server.
5905 * Added client_internal.h to include some of the structures
5906 there instead of client.h in lib/silcclient/.
5908 * Added function silc_task_unregister_by_callback to unregister
5909 timeouts by the callback function.
5911 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Some "Incomplete WHOIS info" errors has been appearing on the
5914 log files. Took away the entry->userinfo check from WHOIS
5915 reply sending. The entry->userinfo is now " " if client did not
5916 provide one. I thought this was fixed earlier but something
5917 is wrong still. Let's see if the error still appears.
5919 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Fixed a minor bug in the login when the channel key is
5922 re-generated in the server. It used to generate the key in
5923 wrong order and thus caused problems in the channel traffic.
5925 * Fixed a minor bug in channel key distsribution after
5926 KICK command. The key was not sent to the router even though
5929 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added silc_ske_process_key_material_data as generic routine
5932 to process any key material as the SILC protocol dictates. The
5933 function is used by the actual SKE library but can be used by
5934 applications as well. This relates to the private message keys
5935 and the channel private keys since they must be processed the
5936 same way the normal SILC session keys. The protocol dictates
5937 this. Affected files: lib/silcske/silcske.[ch].
5939 Added also silc_ske_free_key_material to free the
5940 SilcSKEKeyMaterial structure.
5942 * Defined silc_cipher_set_key function to set the key for
5943 cipher without using the object's method function. The affected
5944 files: lib/silccrypt/silccipher.[ch].
5946 * Implemented silc silc_client_add_private_message_key,
5947 silc_client_add_private_message_key_ske,
5948 silc_client_del_private_message_key,
5949 silc_client_list_private_message_keys and
5950 silc_client_free_private_message_keys functions in the
5953 Added functions silc_client_send_private_message_key to send
5954 the Private Message Key payload and silc_client_private_message_key
5955 to handle incoming Private Message Key payload.
5957 * Added Cipher field to the Private Message Key payload to set
5958 the cipher to be used. If ignored, the default cipher defined
5959 in the SILC protocol (aes-256-cbc) is used.
5961 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Removed lib/silcclient/ops.h file.
5965 Redefined parts of the SILC Client Library API. Created new
5966 file silcapi.h that deprecates the ops.h file and defines the
5967 published Client Library API. Defined also private message key
5968 API and channel private key API into the file.
5970 This is the file that the application must include from the
5971 SILC Client Library. Other files need not be included by
5972 the application anymore.
5974 * Added new key_agreement client operation callback and also
5975 defined the Key Agreement library API for the application.
5977 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5980 is used by clients to request key negotiation between another
5981 client in the SILC network. If the negotiation is started it
5982 is performed using the SKE protocol. The result of the
5983 negotiation, the secret key material, can be used for example
5984 as private message key.
5986 Implemented the Key Agreement payload into the files
5987 lib/silccore/silauth.[ch].
5989 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Redefined ciphers for the SILC protocol. Added some new ciphers
5992 and defined the key lengths for the algorithms. Changed the
5993 code accordingly. The default key length is now 256 bits.
5995 * Fixed SKE key distribution function silc_ske_process_key_material
5996 when the key length is more than 128 bits. The default key
5997 length in SILC is now 256 bits.
5999 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6000 to indicate unsupported algorithm.
6002 * Renamed rijndael.c to aes.c and all functions as well.
6004 * Fixed a long standing channel key setting bug in client library.
6005 Weird that it has never surfaced before.
6007 * Fixed bug in channel deletion. If the entire channel is removed
6008 then it must also delete the references of the channel entry
6009 from the client's channel list as the client's channel entry and
6010 the channel's client entry share same memory.
6012 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Implemented CONNECT and SHUTDOWN commands in the client.
6016 * Implemented CLOSE command to the client.
6018 * Added the function silc_idlist_find_server_by_name into the
6019 files silcd/idlist.[ch].
6021 Added the function silc_idlist_find_server_by_conn into the
6022 files silcd/idlist.[ch].
6024 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * DIE command was renamed to SHUTDOWN. Updated the both code
6029 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6030 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6032 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6035 * Added function silc_server_create_connection function to create
6036 connection to remote router. My server implementation actually
6037 does not allow router to connect to normal server (it expects
6038 that normal server always initiates the connection to the router)
6039 so the CONNECT command is only good for connecting to another
6042 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6045 or some other client was kicked from the channel.
6047 Implemented the handling of the notify type to both client
6050 Implemented silc_server_send_notify_kicked to send the KICKED
6051 notify. It is used to send it to the server's primary router.
6053 * Implemented the KICK command into server and client.
6055 * Added `query' argument to the silc_idlist_get_client function
6056 to indicate whether to query the client from server or not if
6059 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6060 to indicate that the client is not channel founder.
6064 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Removed the rng context from SilcPacketContext structure and
6067 changed that the packet routine uses the Global RNG API.
6069 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Added support for quit message that client can "leave" on the
6072 channel when it quits the SILC. It is ditributed inside the
6073 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6075 Added silc_server_free_client_data that will take the
6076 signoff message as argument.
6078 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6080 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Updated parts of the protocol specification to keep it up
6085 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6088 payloads in one packet.
6090 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6091 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6092 use now the new List flag.
6094 * Also deprecated the following packet types: REPLACE_ID,
6095 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6097 * Added list support for Notify packet in server.
6099 * Added silc_server_send_notify_channel_change to send the
6100 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6101 the silc_server_send_replace_id.
6103 * Added silc_server_send_notify_nick_change to send the
6104 NICK_CHANGE notify type. Deprecates the function
6105 silc_server_send_replace_id.
6107 * Added silc_server_send_notify_join to send the JOIN notify type.
6108 Deprecates the function silc_server_send_new_channel_user.
6110 * Added silc_server_send_notify_leave to send LEAVE notify type.
6111 Deprecates the function silc_server_send_remove_channel_user.
6113 * Added silc_server_send_notify_cmode and
6114 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6115 types. Deprecates the silc_server_send_set_mode function.
6117 * Added SERVER_SIGNOFF notify type to indicate that server has
6118 quit. This means that all clients on the channel from that
6119 server will drop. This can be also used when netsplit happens.
6121 Deprecated REMOVE_ID packet type since it is not needed anymore
6124 Added silc_server_send_notify_server_signoff to send the
6125 SERVER_SIGNOFF notify type. Deprecates the function
6126 silc_server_send_remove_id.
6128 Added also silc_server_send_notify_signoff to send the
6129 SIGNOFF notify type.
6131 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6132 SILC protocol from this day on. Changed the protocol
6133 specification as well.
6135 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6136 notify type. It is used between routers to notify about
6137 topic changes on a channel.
6139 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6142 * Partly updated the protocol specification to comply with the
6143 changes now made. It is still though a bit outdated.
6145 * The JOIN notify type now takes one extra argument <Channel ID>.
6146 The packet used to be destined to the channel but now the
6147 JOIN type may be sent as list thus it is impossible to
6148 destine it to any specific channel. By adding this argument
6149 it is again possible.
6151 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Added CREDITS file. The CHANGES and CREDITS file will appear
6154 in the distribution as well.
6156 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6159 types in the server's silcd/packet_receive.c.
6161 * Implemented CMODE and CUMODE to work in router environment.
6163 * Fixed minor encoding and decoding buglet from the
6164 lib/silccore/silcmode.c.
6166 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6169 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6171 * Changed all SilcConfigServer* and silc_config_server* to
6172 SilcServerConfig* and silc_server_config*, respectively.
6175 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Associated the ID (client or server ID) to the Authentication
6178 Payload to avoid any possibility of forging. Updated the
6179 protocol specification and the code accordingly.
6181 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * The RSA key length is now save to the RsaKey context in the
6184 key generation process in lib/silccrypt/rsa.c. The key length
6185 is now used to figure out the maximum size of the block allowed
6186 to be encrypted/signed.
6188 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6189 is equivalent to the silc_mp_mp2bin but does not allocate any
6192 * Changed silc_mp_mp2bin API to take length argument. If it is
6193 non-zero then the buffer is allocated that large. If zero, then
6194 the size is approximated using silc_mp_sizeinbase, which however
6197 * Created Global RNG API which is global RNG that application can
6198 initialize. After initializing, any routine anywhere in the
6199 code (including library) can use RNG without allocating a new
6200 RNG object. This was done to allow this sort of use of the
6201 RNG in code that has no chance to allocate RNG object. All
6202 applications currently allocate this and many routines in the
6203 library use this. Affected file lib/silccrypt/silcrng.[ch].
6205 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6206 it to use the Global RNG API.
6208 * Defined Authentication Payload into protocol specification that
6209 is used during SILC session to authenticate entities. It is
6210 used for example by client to authenticate itself to the server
6211 to obtain server operator privileges.
6213 Implemented this payload into the lib/silccore/silcauth.[ch].
6214 Implemented also routines for public key based authentication
6215 as the new protocol specification dictates.
6217 Moved definitions of different authentication methods from
6218 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6220 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6221 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6222 silc_pkcs_verify_with_hash functions into the file
6223 lib/silccrypt/silcpkcs.[ch].
6225 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * The client entry's userinfo pointer must be always valid.
6228 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6229 will fail since it requires the userinfo. Now, the userinfo
6230 is allocated as "" if actual userinfo does not exist. Actually,
6231 it must exist and it is totally Ok to drop client connections
6232 that does not announce the userinfo. However, we will make
6233 this workaround for now.
6235 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6236 to return the remote port by socket.
6238 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6241 SILC_SERVER_PENDING_EXEC and added an new macro
6242 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6243 data or when error occurs while processing the pending command.
6245 Added new argument `destructor' into silc_server_command_pending
6246 and to the SilcServerCommandPending object. This destructor is
6247 now called after calling the pending callback or if error occurs
6248 immediately. If error occurs the actual pending callback won't
6249 be called at all - only the destructor. The destructor may be
6250 NULL if destructor is not needed.
6252 All this applies for client library code as well. Similar
6253 changes were made there as well for the pending commands.
6255 In the client, the application must now allocate the
6256 SilcClientCommandContext with the silc_client_command_alloc
6259 * Added reference counter to the SilcServerCommandContext. Added
6260 function silc_server_command_alloc and silc_server_command_dup
6263 Same type of functions added to the client library for the same
6266 * Removed the cmd_ident from IDListData away since it is now
6267 global for all connections. It is the command identifier used
6268 in command sending and with pending commands. The affected file
6271 * Added reference counter to the SilcSocketConnection objecet to
6272 indicate the usage count of the object. The object won't be
6273 freed untill the reference counter hits zero. Currently only
6274 server uses this, and client ignores it. The client must be
6275 set to use this too later. The affected files are
6276 lib/silccore/silcsockconn.[ch]. Added also the function
6277 silc_socket_dup to increase the reference counter.
6279 This was mainly added because it is possible that the socket
6280 is removed underneath of pending command or other async
6281 operation. Now it won't be free'd and proper DISCONNECTING
6282 flags, etc. can be set to avoid sending data to connection that
6283 is not valid anymore.
6285 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6286 the connection. After that it sets SILC_SET_DISCONNECTED.
6287 It is, however, possible that the socket data is not still freed.
6288 The silc_server_packet_process now checks that data is not
6289 read or written to connection that is DISCONNECTED. The socket
6290 get's freed when the reference counter hits zero.
6292 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Changed the client operation API: channel_message operation's
6295 `sender' is now the client entry of the sender, not the nickname
6296 and the `channel' is the channel entry, not the channel name.
6298 In the private_message operation the `sender' is now also the
6299 client entry of the sender not the nickname.
6301 Affected file is lib/silcclient/ops.h and all applications
6302 using the client operations.
6304 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Moved the calling of ops->connect() from connect_to_server_final
6307 into receive_new_id functin since that is the point when the
6308 client is actually allowed to send traffic to network. The
6309 affected file is lib/silcclient/client.c.
6311 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6314 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6315 (if needs broadcasting) instead of broadcasting the packets one
6316 by one which would make a burst in the network traffic.
6318 * Added `broadcast' argument to the functions in silcd/server.[ch]
6319 silc_server_create_new_channel[_with_id] to indicate whether
6320 to send New Channel packet to primary router.
6322 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Added new function into the silcd/server.[ch] files:
6325 silc_server_create_new_channel_with_id to create new channel with
6326 already existing Channel ID.
6328 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6329 lib/silccore/silcpacket.h. This packet is used t send list of
6330 Set Mode payloads inside one packet. Server uses this to set
6331 the modes for the channels and clients on those channels, that it
6332 announced to the router when it connected to it. The protocol
6333 specification has been updated accordingly.
6335 * The silc_server_new_channel did not handle the packet coming
6336 from normal server as it normally does not send that. However,
6337 when it announces its channels it does send it. Implemented
6338 the support for that.
6340 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6341 into the file lib/silccore/id.h.
6343 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Fixed memory leaks in the functions silc_idlist_del_client,
6346 silc_idlist_del_channel and silc_idlist_del_server in the file
6347 silcd/idlist.c. All of those leaked like a sieve.
6349 * Fixed some small memory leaks in the client's function
6350 silc_client_notify_by_server.
6352 * Added functions into silcd/server.c: silc_server_announce_clients,
6353 silc_server_announce_channels and silc_server_announce_server.
6354 These functions are used by normal and router server to announce
6355 to its primary router about clients, channels and servers (when
6356 router) that we own. This is done after we've connected to the
6359 These functions effectively implements the following packet types:
6360 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6361 and SILC_PACKET_NEW_ID_LIST.
6363 * Added new functions into the silcd/packet_receive.[ch]:
6364 silc_server_new_id_list, silc_server_new_channel_list and
6365 silc_server_new_channel_user_list to handle the incoming
6366 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6368 * Added support of changing Channel ID in the function
6369 silc_server_replace_id. If the server that announces a channel
6370 to the router already exists in the router (with same name but
6371 with different Channel ID), router is responsible to send
6372 Replace ID packet to the server and force the server to change
6373 the Channel ID to the one router has.
6375 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6376 client that the Channel ID has been changed by the router. The
6377 normal server sends this to the client. Client must start using
6378 the new Channel ID as the channel's ID.
6380 Implemented handling of this new type into lib/silcclient/client.c
6381 into the function silc_client_notify_by_server.
6383 * Added new function silc_idlist_replace_channel_id into the files
6384 silcd/idlist.[ch] to replace the Channel ID.
6386 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Call silc_server_command_identify_check always when processing
6389 the IDENTIFY command in silcd/command.c
6391 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6394 send keepalive packets. The packet can be sent by clients,
6395 servers and routers.
6397 Added function silc_socket_set_heartbeat into the file
6398 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6399 If not set, the heartbeat is not performed. The actual
6400 heartbeat is implemented in the low level socket connection
6401 library. However, application is responsible of actually
6404 Added silc_server_send_heartbeat to send the actual heartbeat
6405 packet into silcd/packet_send.[ch]. Server now performs
6406 keepalive with all connections.
6408 * Added silc_task_get_first function into lib/silcutil/silctask.c
6409 to return the timeout task with shortest timeout. There was a bug
6410 in task unregistration that caused problems. TODO has been
6411 updated to include that task system must be rewritten.
6413 * The client library will now resolve the client information when
6414 receiving JOIN notify from server for client that we know but
6415 have incomplete information.
6417 * Rewrote parts of silc_server_remove_from_channels and
6418 silc_server_remove_from_one_channel as they did not remove the
6419 channel in some circumstances even though they should've.
6421 * Encryption problem encountered in server:
6423 The LEAVE command used to send the Channel Key packet to the
6424 router immediately after generating it. However, the code
6425 had earlier sent Remove Channel user packet but not immediately,
6426 ie. it was put to queue. The order of packets in the router
6427 was that Channel Key packet was first and Remove Channel User
6428 packet was second, even though they were encrypted in the
6429 reverse order. For this reason, MAC check failed. Now, this
6430 is fixed by not sending the Channel Key packet immediately but
6431 putting it to queue. However, this is more fundamental problem:
6432 packets that are in queue should actually not be encrypted
6433 because packets that are sent immediately gets encrypted
6434 actually with wrong IV (and thus MAC check fails). So, packets
6435 that are in queue should be encrypted when they are sent to
6436 the wire and not when they put to the queue.
6438 However, the problem is that the current system has not been
6439 designed to work that way. Instead, the packet is encrypted
6440 as soon as possible and left to the queue. The queue is then
6441 just purged into wire. There won't be any fixes for this
6442 any time soon. So, the current semantic for packet sending
6445 o If you send packet to remote host and do not force the send
6446 (the packet will be in queue) then all subsequent packets to the
6447 same remote host must also be put to the queue. Only after the
6448 queue has been purged is it safe again to force the packet
6451 o If you send all packets immediately then it safe to send
6452 any of subsequent packets through the queue, however, after
6453 the first packet is put to queue then any subsequent packets
6454 must also be put to the queue.
6456 Follow these rules and everything works fine.
6458 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Added new function silc_server_remove_clients_by_server to
6461 remove all client entries from ID list when the server connection
6462 is lost. In this case it is also important to invalidate all
6463 client entires as they hold the invalid server entry. This
6464 fixes fatal bug when server has lost connection and will reconnect
6467 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Made some sanity checks to silc_server_daemonise like to check
6470 whether the requested user and group actually exists.
6472 * Added sanity check to SKE's silc_ske_responder_finish to check
6473 that the public and private key actually is valid.
6475 * Invalidate the client's nickname when receiving Replace ID
6476 packet and the Client ID is being replaced. This means that the
6477 server will query the nickname if someone needs it (client)
6480 * Sort the ID Cache in client library when the ID Cache data
6481 has changed (needs sorting).
6483 * Do not allow for SILC client to create several connections to
6484 several servers. The client does not support windows right now
6485 and generating multiple connections causes weird behaviour.
6487 Irssi-silc client does support windows and can handle several
6488 connections without problems, see: www.irssi.org and SILC plugin.
6490 * Fixed some places where client was added to the IDList. The
6491 rule of thumb is following (in order to get everything right):
6492 If the client is directly connected local client then the
6493 `connection' argument must be set and `router' argument must be
6494 NULL to silc_idlist_add_client function. If the client is not
6495 directly connected client then the `router' argument must
6496 bet set and the `connection' argument must be NULL to the
6497 silc_idlist_add_client function.
6499 * The funtion silc_server_packet_send_local_channel actually did
6500 not check whether the client was locally connected or not. It
6501 does that now. Fixed a bug related to LEAVE command.
6503 * Fixed Remove Channel User payload parsing bug in server's
6504 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6506 * The server's silc_server_save_channel_key now checks also the
6507 global ID list for the channel as it might not be in the local
6508 list. Fixed a bug related to LEAVE command.
6510 * Is this the end of the [<unknown>] buglet that has been lurking
6511 around for a long time? A little for loop fix in server's
6512 silc_server_command_whois_parse that is used by both IDENTIFY
6513 and WHOIS command. At least, this was a clear bug and a cause
6514 of one type of [<unknown>] buglet.
6516 * WHOIS and IDENTIFY commands call the function
6517 silc_server_command_[whois/identify]_check function even if
6518 we are not router server.
6520 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Added --with-gmp configuration option. If set the GMP
6523 is always compiled in the SILC source tree. If not set then
6524 it is checked whether the system has the GMP3 installed. If
6525 it has then the GMP won't be compiled (the system's headers
6526 and library is used), if it doesn't have it then the GMP is
6527 compiled in the SILC source tree.
6529 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Changed RSA private exponent generation to what PKCS #1
6532 suggests. We try to find the smallest possible d by doing
6533 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6534 not security fix but optimization.
6536 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Added new config entry [Identity] to fork the server and run
6539 it as specific user and group. A patch from Bostik.
6541 * Imported Dotconf configuration library into lib/dotconf.
6542 This will be used to create the SILC configuration files later.
6543 It will appear in the distsribution after this commit.
6545 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * A big code auditing weekend happening. Auditing code for
6548 obvious mistakes, bugs and errors. Also, removing any code
6551 Removed files for being obsolete:
6553 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6554 inline in the file lib/silcutil/silcbuffer.h)
6556 o lib/silcutil/silcbufutil.c (the header has inline versions)
6558 Changed code to fix possible error conditions:
6560 o The buffer formatting routines now check that the destination
6561 buffer really has enough space to add the data. This applies for
6562 both buffer formatting and unformatting
6563 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6564 unformatting was changed to accomodate following rules:
6565 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6566 sent to the function while XXX_*STRING will not allocate or copy
6567 the data into the buffer. Instead it sets the pointer from the
6568 buffer into the pointer sent as argument (XXX_*STRING used to
6569 require that the pointer must be allocated already). This change
6570 makes this whole thing a bit more consistent and more optimized
6571 (note that the data returned in the unformatting with XXX_*STRING
6572 must not be freed now). The routines return now -1 on error.
6574 o Tried to find all code that use buffer_format and buffer_unformat
6575 and added return value checking to prevent formatting and
6576 especially unformatting errors and possible subsequent fatal
6579 o Changed ske->x and ske->KEY to mallocated pointers in
6580 lib/silcske/silcske.h. Fixed possible data and memory leak.
6582 o Added return value checking to all *_parse* functions. Fixed
6583 many memory leaks as well.
6585 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6586 so that buffer overflows would not happen. All code now also
6587 checks the return value as it can fail.
6589 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Added reconnection support to server if the normal server looses
6592 its connection to the router (for example if router is rebooted).
6593 The server performs normal reconnection strategy implemented
6594 to the server. Affected file silcd/server.c.
6596 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Added new packet type SILC_PACKET_SET_MODE that is used to
6599 distribute the information about changed modes (for clients,
6600 channels and clients channel modes) to all routers in the
6601 network. Updated the protocol specification accordingly.
6603 Added functions into silcd/packet_send.c and
6604 silcd/packet_receive.c: silc_server_send_set_mode,
6605 silc_server_set_mode.
6607 Added new files silcmode.[ch] into lib/silccore that implements
6608 the encoding and decoding of Set Mode Payload. Added new type
6609 SilcSetModePayload. Moved the definitions of different modes
6610 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6612 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Oops, a little mistake in server's connection authentication
6615 protocol. The protocol is not ended with FAILURE but with
6616 SUCCESS if the authentication is Ok. :) Affected file is
6619 * Implemented NICK_CHANGE notify handling in server in the file
6620 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6621 the local clients on the channel. After the changing nickname
6622 in router environment snhould work and the [<unknown>] nickname
6623 should appear no more.
6625 The silc_server_replace_id function that receives the Replace ID
6626 payload now sends the NICK_CHANGE notify type also in the file
6627 silcd/packet_receive.c
6629 * Changed WHOIS and IDENTIFY command to support the maximum amount
6630 of arguments defined in protocol specs (3328 arguments). This
6631 fixed a bug that caused problems when there were more than three
6634 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Added extra parameter, command identifier, to the
6637 silc_client_send_command so that explicit command identifier
6640 Changed that ID list routines uses specific command identifier
6641 when sending WHOIS/IDENTIFY requests to the server so that they
6642 can be identified when the reply comes back.
6644 Affected files lib/silcclient/command.[ch],
6645 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6647 * Added `sender' argument to silc_server_packet_send_to_channel
6648 to indicaet the sender who originally sent the packet to us
6649 that we are now re-sending. Ignored if NULL. Affected file
6650 silcd/packet_send.[ch].
6652 * Added some server statistics support in silcd/server_internal.h
6653 SilcServerStatistics structure and around the server code. Also
6654 send some nice statistics information when client is connecting
6657 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Fixed channel ID decoding in server's JOIN command reply in
6660 silcd/command_reply.c
6662 * Fixed braodcasting of replace ID payload to not to send it if
6663 we are standalone server in silcd/packet_receive.c.
6665 * Fixed all channel message sending routines to not to send
6666 packets to clients that has router set, since they are routed
6667 separately in the same function earlier. Affects file
6668 silcd/packet_send.c and all channel packet sending functions.
6670 * In USERS reply, res_argv[i] are not allocated, the table
6671 is allocated. Thus changed that free the table, not its
6674 * In server's whois_check and identify_check if the client is
6675 locally connected do not send any WHOIS commands - they are not
6678 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed some minor bugs in client when sending WHOIS command. The
6681 arguments was in wrong order.
6683 * Removed statis function add_to_channel from server in
6684 silcd/command.c that was previously used with the joining but
6687 * Tested USERS command in router environment successfully with two
6688 routers, two servers and two clients.
6690 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Reorganized the USERS command and command reply in client library
6693 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6694 When the command is given by user we register a pending command
6695 callback that will reprocess the command after the reply has been
6696 received from the server. When reprocessing the packet we then
6697 display the information. Thus, the USERS information is displayed
6698 now in the command callback instead of in the command reply
6699 callback. The processing of the command is same as previously
6700 when server has sent the command reply in the JOINing process.
6702 * Added to USERS command in silcd/command_reply.c to join the client,
6703 we didn't use to know about, to the channel after we've created
6704 a client entry for it. Also, for clienet we did know already still
6705 check whether it is on the channel or not and add it if not.
6707 * Removed silc_server_command_join_notify as the function and its
6710 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Changed the client's pending command handling to the same as the
6713 server's pending command handling. It is also now possible to
6714 execute command reply functions from other command reply
6715 function as the function callbacks for commands and command
6716 replies are one and same. The pending commands are not static
6717 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6718 in client connection context. Thus, pending commands are server
6719 connection specific as it is convenient.
6721 Changed the function silc_client_command_pending and
6722 silc_client_command_pending_del and added new function
6723 silc_client_command_pending_check. Removed the
6724 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6727 * Added cmd_ident, current command identifier, to the client
6728 connection context in lib/silcclient/client.h to keep track on
6729 command identifiers used in command sending. Client's command reply
6730 function handling now supports the mandatory command identifiers.
6732 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6733 funtions in client to fully support pending command callbacks.
6735 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6736 as one of the arguments to the application in the command reply
6739 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6740 before first releasing SILC but came back. Now it is removed again
6741 and should come back nomore. The FORWARDED flag was used only
6742 by the JOINing procedure by forwarding the command packet to router.
6743 Now, the JOINing procedure has been changed to more generic (due
6744 to various router environment issues) and FORWARDED is not needed
6745 anymore for anything. The protocol specification is yet to be
6748 Now, removed silc_server_packet_forward from server and the flag
6749 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6751 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Renamed NAMES command to USERS command. The NAMES was named that
6754 due to historical reasons. Now it is renamed. Also, rewrote
6755 parts of the USERS command. The nickname list is not sent anymore
6756 by the server. Only Client ID and mode lists are sent in the USERS
6757 command. Changed this also to the protocol specification.
6759 The client now resolves the names and stuff after it receives
6760 the USERS list from the server when joining to the channel.
6762 * WHOIS and IDENTIFY commands has been changed to support multiple
6763 Client ID's per command. One can now search for multiple users
6764 in the network by sending only one WHOIS or IDENTIFY command.
6765 Changed the code and the protocol specifications.
6767 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6768 uses silc_server_command_whois_parse to parse the request. */
6770 * If normal server, do not parse the WHOIS and IDENTIFY requests
6771 before sending it to the router. Saves some time.
6773 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * Fixed JOIN command on client library. Wrong number of arguments
6776 used to crash the client.
6778 * Added silc_server_channel_has_global function to check whether
6779 channel has global users or not.
6781 * Added silc_server_channel_has_local function to check whether channel
6782 has locally connected clients on the channel.
6784 * The silc_server_remove_from_one_channel now checks whether the
6785 channel has global users or not after given client was removed from
6786 the channel. It also checks whether the channel has local clients
6787 on the channel anymore. If it does not have then the channel entry
6788 is removed as it is not needed anymore.
6790 * The silc_server_notify now checks on JOIN notify whether the joining
6791 client is one of locally connected or global. If it is global then
6792 the channel has now global users on the channel and that is marked
6793 to the channel entry. Also, it now saves the global client to
6794 global list who is joining and JOINs it to the channel. This is
6795 for normal server, that is.
6797 Changed silc_server_send_notify_on_channel,
6798 silc_server_packet_relay_to_channel and
6799 silc_server_packet_send_to_channel check if we are normal server
6800 and client has router set (ie. global client) do not send the
6801 message to that client, as it is already routed to our router.
6803 * Implemented LEAVE notify type handling in silc_server_notify
6806 * Tested LEAVE command in router environment successfully. Tested
6807 with two routers, two servers and two clients.
6811 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6813 * Implemented SIGNOFF notify type handling in silc_server_notify
6816 * silc_server_remove_id now removes the client entry from all channels
6817 it has joined and thusly sends SIGNOFF notify type.
6819 * Rewrote the NAMES list generation in server by removing two excess
6820 loops. The lists are created now inside one loop.
6822 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * silc_server_remove_channel_user checks now also global list
6825 for channel and client.
6827 * silc_server_new_channel_user checks now both local and global
6828 list for channel and client. Fixed a bug in client id decoding.
6829 Used to decode wrong buffer.
6831 * silc_server_channel_message checks now both local and global
6832 list for channel entry.
6834 * Tested channel joining (hence JOIN) in router environment
6835 successfully. Tested with two routers, two servers and two
6838 * Tested channel message sending in router environment successfully.
6840 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Added silc_server_save_channel_key into server.[ch] to save the
6843 received channel key in Channel Key payload processing. It is
6844 also used in JOIN command reply handling.
6846 Equivalent function silc_client_save_channel_key added into
6847 client.[ch] into client library.
6849 * Changed JOIN command reply to send information whether the channel
6850 was created or not (is existing already) and the channel key
6851 payload. Changed protocol specs accordingly.
6853 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6854 the request was sent by ID and not by nickname. Crashed on
6857 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6860 now correctly save the received data.
6862 * silc_server_free_sock_user_data now notifies routers in the
6863 network about entities leaving the network.
6865 At the same time implemented functions silc_server_remove_id
6866 and silc_server_send_remove_id to receive and send REMOVE_ID
6867 packets. The packet is used to notify routers in the network
6868 about leaving entities. The ID removed will become invalid in
6871 * Added function silc_idlist_del_server into server. Removes and
6872 free's server entry from ID list.
6874 * silc_server_private_message function now checks, if we are router,
6875 that the destination ID really is valid ID, naturally.
6877 * In router when NEW_ID packet is received (for new client) the
6878 hash of the Client ID is saved in the ID Cache but the
6879 client->nickname is set to NULL, instead of putting the hash
6882 IDENTIFY command now also checks that client->nickname must be
6883 valid. If it is not if will request the data from the server who
6884 owns the client. Added new function
6885 silc_server_command_identify_check.
6887 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6888 to set the command to already allocated Command Payload.
6890 * Tested private message sending in router environment with two
6891 routers, two servers and two clients. Fixed minor bugs and now
6894 * Fixed segfault from client's NAMES command. Used to crash if
6897 * Forwarded packets must not be routed even if it is not destined
6898 to the receiver. Changed server code comply with this.
6900 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Added `require_reverse_mapping' boolean value to ServerParams
6903 structure. If TRUE (not default) the server will require that
6904 the connecting host has fully qualified domain name.
6906 If the reverse mapping is not required and hostname could not be
6907 found the IP address is used as hostname.
6909 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Implemented version string checking to both client and server.
6912 The check is incomplete currently due to the abnormal version
6913 strings used in development version of SILC.
6915 * Changed all command functions in server to use the new
6918 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * Changed char *data to unsigned char *data in ID Cache system to
6921 support binary data as ID Cache data. Changed code to support
6922 binary data in lib/silccore/idcache.c.
6924 * Renamed silc_server_packet_relay_command_reply to
6925 silc_server_command_reply as it is normal packet receiving
6926 function. Rewrote the function to accept command replys for
6927 servers and not only for clients.
6929 * Mark remote router always as registered server if we are connecting
6930 to it. Otherwise, commands sent by the router to us are ignored.
6932 * All ID List find routines now returns the ID Cache Entry pointer
6933 as well if requested.
6935 * WHOIS command works now in router environment, tested with two
6936 routers, two servers and two clients.
6938 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6939 in router environment (as it is almost equivalent to WHOIS) but
6940 hasn't been tested thoroughly. Added new functions:
6942 silc_server_command_identify_parse
6943 silc_server_command_identify_send_reply
6944 silc_server_command_identify_from_client
6945 silc_server_command_identify_from_server
6947 * Disabled route cache adding because adding two different ID's with
6948 same IP replaces the old cache entry thus giving wrong route.
6949 The entry->router->connection is always the fastest route anyway
6950 so route cache may not be needed. Of course, new routes maybe
6951 established after receiving the ID when the entry->router->connection
6952 might not be anymore the most optimal.
6954 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6956 * Add route cache for received ID for fast routing.
6958 * Added silc_server_packet_route to route received packet on router
6959 that is not destined to us.
6961 * Renamed silc_server_get_route to silc_server_route_get.
6963 * Added id_string and id_string_len fields into SilcServer to
6964 include encoded ServerID for fast comparing without excess
6965 encoding of the ID's.
6967 * Cleaned up WHOIS command on server side. Added following static
6970 silc_server_command_whois_parse
6971 silc_server_command_whois_check
6972 silc_server_command_whois_send_reply
6973 silc_server_command_whois_from_client
6974 silc_server_command_whois_from_server
6976 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6977 arguments in command replies. All command functions should be
6978 updated to use this macro.
6980 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6982 * Minor typo fixes on command reply handling on server.
6984 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Added silc_server_command_add_to_channel internal routine to add
6987 the client to the channel after router has created the channel and
6988 sent command reply to the server.
6990 * Added generic silc_server_send_command to send any command from
6993 * Use static buffer with ID rendering instead of duplicating data.
6995 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * Fixed a channel user mode bug when joining to a channel server gave
6998 everybody channel founder rights, oops.
7000 * We mark ourselves as the router of the incoming server connection
7001 if we are router ourselves. This way we can check in some packet
7002 sending functions whether it is locally connected server. For
7003 incoming router connections we put NULL.
7005 * For router sending packets locally means now always sending the
7006 packet cell wide; to local clients and local servers. For normal
7007 server sending packet locally means sending it to only local
7010 * Fixed the JOIN command to really work in router environment. If the
7011 channel is created it is always created by the router. Router is
7012 also responsible of making the initial joining to the channel,
7013 sending JOIN notify to the sending server and distributing
7014 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7015 does not exist server doesn't do anything else but forward the
7016 command to the router which performs everything.
7018 * Added silc_server_send_channel_key function to send the Channel Key
7021 * Added silc_server_create_channel_key to create new channel key. The
7022 channel key is now re-generated everytime someone joins or leaves
7023 a channel, as protocol dictates. Note: channel->key_len is the
7026 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7029 packet_receive.[ch] to separate packet sending and receiving
7030 routines. The server.[ch] now includes everything else including
7031 actual packet processing (writing and reading data) and other
7034 Renamed silc_server_private_message_send_internal to
7035 silc_server_send_private_message. The routine is still though
7036 used only to relay private messages as server does not send
7037 private messages itself.
7039 Renamed silc_server_new_channel to silc_server_create_new_channel
7040 and added new function sicl_server_new_channel that handles the
7041 incoming New Channel packet. Added also new sending function
7042 silc_server_send_new_channel to send New Channel Payload.
7044 * Added new function silc_server_notify to process incoming notify
7045 packet to the server/router. Server may then relay the notify
7046 to clients if needed.
7048 * Added new function silc_server_new_channel_user to process incoming
7049 New Channel User packet. Router will redistribute the packet and
7050 send JOIN notify to its local clients and locally connected servers
7051 if needed. Normal server will send JOIN notify to its local client
7052 on same channel when received this packet. Added also corresponding
7053 sending function silc_server_send_new_channel_user to sent the
7056 * Added boolean route argument to send_notif_to_channel and
7057 packet_send_to_channel functions to attempt to route the packet
7058 if it is TRUE and send only locally if it is FALSE.
7060 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7062 * silc_server_replace_id now broadcasts the received replace ID
7063 packet if it is not broadcast packet already. The router must
7064 broadcast to inform other routers about changed ID.
7066 * Added backpointer to server's router into SilcServer context in
7067 silcd/server_internal.h.
7069 * Fixed silc_server_packet_broadcast to send correct broadcast
7072 * The channel key is now distributed to the local client as soon
7073 as it is received from the router (in router environment) so that
7074 no other packet may be sent for the channel until client has
7077 * silc_server_remove_channel_user now broadcasts the received
7078 Remove Channel User packet if it is not broadcast packet already.
7079 The router must broadcast to inform other routers about removed
7082 * Added users field into SilcPacketContext that is a reference count
7083 of the context. One can increase the reference count by calling
7084 silc_packet_context_dup which is now changed to just increase the
7085 reference count instead of duplicating the data. The reference
7086 count is decresed by calling silc_packet_context_free that will
7087 free the data after the reference count hits zero.
7089 For now on the packet context and everything allocated into it
7090 (including the raw packet from network) must be freed by calling
7091 the new silc_packet_context_free function. Added also new function
7092 silc_packet_context_alloc that must be used now to allocate the
7093 context. This also means that if a routine is asynchronous from
7094 silc_[client/server]_packet_parse_type the packet context must
7095 be duplicated by calling silc_packet_context_dup. Otherwise it
7096 gets free'd after silc_[client/server]_packet_parse_type returns.
7097 Also, one must remember that if packet is duplicated then its
7098 reference count must be decresed by calling the free function as
7099 many times as it was duplicated.
7101 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7102 from both client and server.
7104 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Made joining to a channel working in router environment.
7108 * Cleaned up JOIN command on server side and create function
7109 silc_server_command_join_channel internal routine to make the
7112 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Changed silc_command_pending list to SilcDList. Also, added
7115 `ident' field to SilcServerCommandPending structure to identify
7116 the reply and to call correct callback.
7118 Added silc_server_command_pending_check function to replace the
7119 corresnponding macro. The silc_command_pending list is not
7122 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7123 to set identifier to previously allocated Command Payload. It
7124 is used to set identifier for command when resending Command
7127 * Added silc_command_payload_encode_payload to encode Command
7128 Payload buffer from SilcCommandPayload structure.
7130 * Added silc_argument_payload_encode_payload to encode Argument
7131 payload buffer from SilcArgumentPayload structure.
7133 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * Changed WHOIS command to support router connection on server side.
7136 The whois request is always sent to router unless the server is
7137 standalone server. After server has received the reply from the
7138 router will it send the reply to the client.
7140 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7141 broadcast received broadcast packet. The function is used only
7142 by router. The broadcast packet is always sent to the router's
7145 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7146 render given ID to printable string, for log files for example.
7148 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Made basic router to router connections working. At least they
7151 can now connect to each other but nothing really works the way
7152 they are supposed - yet.
7154 * Added new initiator token to RouterConnection configuration
7155 file in silcd/serverconfig.[ch]. It is used to tell whether we
7156 are the initiator to the remote router or whether we'll expect
7157 the other end to connect.
7159 * Moved registering of listener task to silc_server_init, hence
7160 the server starts listenning as soon as it is run, even if it
7161 does not have connections to other routers. Let's see how well
7164 * Changed default connection retry timeouts for more suitable in
7167 * Removed cipher and such arguments from silc_idlist_add_client
7168 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7169 Added new function silc_idlist_add_data to add the keys and stuff
7172 * Added SilcIDListData structure and added it to SilcClientEntry
7173 and SilcServerEntry as their first field in the structure. This
7174 way we can explicitly cast the ID entries to the SilcIDListData
7175 structure and get common data for the entries. In past, we had
7176 to first check what type of connection it is and then cast it to
7177 correct ID entry type. Now, we can directly cast the opaque
7178 pointer to the SilcIDListData (no matter what ID entry it actually
7179 is) and get the data needed.
7181 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7184 in some circumstances even if threre were timeout tasks, though not
7185 IO tasks, but tasks anyway. Now fixed.
7187 * Defined SilcServerConnection structure to hold connection specific
7188 stuff about directly connected servers and routers. The definition
7189 is currently in silcd/server_internal.h. I thought about having
7190 a bit more important role fro this struct but for now it is used
7191 only when connecting to other server (or router actually).
7193 * Added connecting retry support in server when connecting to
7194 router(s). The retry feature implement exponential backoff
7195 algorithm. Also, added SilcServerParams structure to hold default
7196 parameters for server. For now, it include these retry settings
7197 and are hard coded. After server is moded to be as Silc Server
7198 Library this structure will be more important.
7200 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Changed client librarys channel->clients table to SilcList and
7203 changed code accordingly.
7205 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Changed client's channel table to SilcList and changed code
7208 accordingly. Also changed SilcChannelClientEntry to include back-
7209 pointer to the channel so that client entry can use that structure
7210 as list as well and we have fast cross-reference to the channel.
7211 This change dramatically decreased the complexity of channel
7212 handling with client entry and vice versa (removed one extra
7213 loop when searching for channel entry from many functions).
7215 * Changed server->sim from table to SilcDList and changed code
7218 * NAMES command can now be used from user interface. It will show
7219 the user list on the channel, neatly.
7221 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7222 Code now saves realname of the user if it becomes available.
7224 * Renamed configure.in to configure.in.pre and made ./prepare
7225 script to automatically add correct version string to
7226 configure.in which it creates from configure.in.pre.
7228 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * NAMES command reply now shows users mode with the nickname when
7233 * Moved silc_client_ch[u]mode[_char] functions from
7234 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7235 place sucks, they are utility functions and should be in some
7238 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7240 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7243 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7247 * Added TRQ (efficient deque and list library) into lib/trq. This is
7248 a very good list library that is currently used in the SILC. Defined
7249 SilcList API over the library because I didn't like the API very
7250 much. See lib/trq/silclist.h for the API and examples of how to
7251 use the API. Fixed various places in the code to use the new
7252 SilcList API. The SilcList is meant for lists that has a structure
7253 already defined as a list. It is not suitable to add just some
7254 context to the list (in TRQ, the context is the list actually).
7256 So, I defined SilcDList that can be used for the purpose where
7257 predefined list structure does not exit. This can be used as
7258 such list. Now some context just can be added to the SilcDList.
7259 Currently this list is not used in the SILC just yet, though there
7260 are a lot places where this can replace dynamically allocated
7261 tables and I will fix these places, later, to use SilcDList.
7262 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7263 and use TRQ internally).
7265 Also fixed some annoying warning messages that the original TRQ
7266 code generated. Also minor changes to TRQ's Makefile.in.
7268 * Added support for querying by Client ID to both WHOIS and
7269 IDENTIFY commands into server, as required by the protocol.
7271 * Removed method function pointers from SilcBuffer structure. They
7272 weren't used to anything and just increased the context size for
7273 no good reason. This change also made silc_buffer_alloc and
7274 silc_buffer_free functions inline functions.
7276 * Disabled command flooding detection support until it's fixed so
7277 that it accepts commands in but does not execute them more than once
7280 * Added silc_net_localhost(), to return local hostname, into
7281 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7282 that must be initialized before calling silc_client_init.
7284 * Added new function: silc_server_send_notify_on_channels to send
7285 notify messages to all channels client has joined. It is assured
7286 that the message is sent only once per client.
7288 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7289 lib/silcutil/silcutil.[ch] as silc_format function. The new
7290 function is generic and is used by server as well, not only by
7291 the logging routines.
7293 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7294 the provided version string was not acceptable. Added new function:
7295 silc_ske_check_version into lib/silcske/silcske.h. The function
7296 must be implemented by the application (client or server) and it
7297 does not reside in the SKE library. The function checks the version
7298 string remote end sent.
7300 * Added back pointers (to opaque context and to SilcSocketConnection)
7301 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7303 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7304 duplicate packet context structure.
7306 * Changed `notify' client operation to send same arguments as client
7307 receives from server except for ID's. ID's are mapped to correct
7308 ID entry and that is returned. Also, if channel entry is not sent
7309 by server but the notify is for channel the channel entry is sent
7310 to application (otherwise application doesn't know that it is for
7311 channel (library gets it from packet's Destination ID)).
7313 * Added silc_client_remove_from_channels into client library to
7314 remove a client from all channels it has joined to. Used when
7315 received SIGNOFF notify from server. Added also new function
7316 silc_client_replace_from_channels to replace old ID entry with
7317 new ID entry on all channels. Used when received NICK_CHANGE
7320 * Fixed ID Cache list handling in silc_idlist_get_client in
7321 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7322 to get (or query) client by ID.
7324 * Updated TODO list.
7326 * Added connection authentication status message defined by the
7327 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7328 support for these into the code in client and server side.
7330 * Added generic function silc_client_send_command to send any command
7331 with variable argument list. Application should use this function
7332 to send commands if the command functions provided by the library
7333 does not suite for the application's user interface needs.
7335 * Added new `failure' client operation. Application is notified about
7336 received failure packet if client is executing a protocol. In this
7337 case the protocol's execution has failed.
7339 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7340 is required by the protocol.
7342 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7343 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7346 * Added status flag to SilcSKE object to indicate realtime status
7347 of the SKE protocol.
7349 * Application receives now exactly same command reply arguments as
7350 the library receives from server. However, if ID is received the
7351 corresponding ID entry is returned to the application (eg. Client
7352 ID is mapped to correct SilcClientEntry entry and that is returned).
7353 Changed command_reply client operation due to this change.
7355 * Changed all ID's in commands and in command replys as ID Payloads.
7356 Change affected both client and server side codes.
7358 All ID's sent in SILC network (with execption of ID's in SILC
7359 Packet header) are sent in ID Payload to support variable length
7362 * Server now notifies nick changes and notifies all clients on
7363 the channels about the new nickname (about the new Client ID,
7366 * Implemented CMODE command to change channel modes. Supports all
7367 channel modes defined by the protocol specs except ban and invite
7368 lists. (Also, private channel key mode is supported but support for
7369 setting private channel key in client is missing, thus, this mode
7370 has no effect on client side (except that server requires that the
7371 client uses private channel key and normal channel traffic does not
7374 Also, invite mode works per se, but INVITE command does not work
7375 yet correctly, so you can set channel as invite only channel but
7376 inviting clients to the channel does not work (it is yet to be
7377 thought what's the best way to do it).
7379 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7380 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7381 Implemented CUMODE command to change user's mode on the channel.
7382 Supports all modes defined by the protocol specs.
7384 * Added NAMES command reply to return users modes on the channel.
7386 * Removed unnecessary and slow ciphers from lib/silccrypt.
7388 * Set SO_KEEPALIVE option to connection sockets by default.
7390 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7392 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7393 redefined the Notify Payload into protocol specs.
7395 * Added silc_id_payload_parse_id to get ID directly from raw
7398 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7400 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7401 accept searching by Client ID as well.
7403 * Added support for LEAVE and SIGNOFF notify types in client library.
7405 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7406 to parse ID Payload from raw data.
7408 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7410 * Added flags parameter into silc_ske_assemble_security_properties
7411 function in lib/silcske/silcske.[ch].
7413 * Changed notify client operation to fit better for notify messages
7414 sent by server. The notify payload received from server is now
7415 passed to the application (after parsing it to SilcNotifyPayload).
7416 It is application's responsibility to retrieve the arguments
7417 from the payload and show the message the way it wants. The message
7418 sent by server is implementation specific.
7420 * Changed public keys to comply with the protocol specification.
7421 Old public keys are not supported anymore and are not compatible.
7423 * Removed nickname from Channel Payload as the latest draft removed
7424 it. The client must resolve the nickname from the NAMES command
7425 reply received when it joined the channel.
7427 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7429 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Fixed some errors in protocol specification drafts.
7433 * Created lib/silccore/silcnotify.c to implement Notify Payload
7434 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7435 generic payloads described by protocol specifications. The file
7436 includes implementations for ID Payload and Argument Payload.
7438 * Changed Command Payload implementation to use the new Argument
7439 Payload. Changed command_xxxx_payload to command_payload_xxxx
7440 to comply with SILC coding conventions.
7442 * Added suppport for Argument Payload handling in Notify Payload
7443 implementation as protocol requires it. Added the new support
7444 into server and client lib as well.
7446 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * Added support for multiple nicknames on same channel. [n] is
7449 added locally to the nickname if there are more than one same
7450 nicknames on the channel.
7452 * Server now sends all nicknames that matched WHOIS request.
7453 Client also shows the list received from server.
7455 * Added TOPIC command to client side. User can now set and show
7456 current topic on channel.
7458 * Added MOTD command to client and server. Also, server sends the
7459 motd when client connects to the server.
7461 * Changed version strings to comply ISO 8601.
7463 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Fixed protocol error handling in client library. It should now
7466 cope even if the SKE fails for some reason.
7468 * Made new protocol specification drafts for submitting to IETF.
7470 * Implemented TOPIC command to server in silcd/command.c.
7472 * Added two new notify types into lib/silccore/silcnotify.h:
7473 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7474 notify nickname change and topic setting/change on a channel.
7476 * API change of command_reply operation in client library. The
7477 application gets now the status type received from server as well.
7479 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7483 * Cras fixed and optimized the packet handling even further and
7484 it should work now. Minor change to the prototype of function
7485 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7487 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * Added new function into lib/silcutil/silcschedule.[ch]:
7490 silc_schedule_with_fd to select() a specified fd. The function
7491 returns after timeout expires or data arrives or goes. The
7492 function is used by packet routines to wait that all data is
7493 received from network.
7495 * Fixed data reading from network in lib/silccore/silcpacket.c.
7496 The code now assures that all data is read from the fd and then
7497 continues packet processing. This was a bug fix since the code
7498 used to drop some data in some circumstances.
7500 * Added new function into lib/silcclient/client.[ch]:
7501 silc_client_start_key_exchange to start key exchange after
7502 connection has been established to server. The code internally
7503 now uses this funtion but its main purpose was to provide it
7504 for applications that perform their own connecting. After
7505 application has created a connection it merely calls this
7506 function to start the key exchange between client and server.
7507 The library takes care of everything else after that.
7509 Updated also lib/silcclient/README to explain the usage of
7512 * Do not send to application information that connection has
7513 been established. Application gets notified it by connect
7516 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7518 * Applied cras's patch to add silc_schedule_one function. The
7519 function runs scheduler once and returns.
7521 * Fixed the scheduler after cras messed it up. The timeout
7522 handling works now as it's supposed to work.
7524 * Added into lib/silccore/ silcnotify.h to include notify
7525 message types support. Changed silc_server_send_notify*
7526 functions, in server.[ch], to support those new notify types.
7527 Added the support for the notify types into client library,
7528 as well. Added new notify client operation into ops.h in
7531 * Changed silc_server_packet_send_to_channel to send normal
7532 packets instead of just channel message packets. The function
7533 is now used to send the notify packets to channels. It is not
7534 used to send channel message packets anymore, as server never
7537 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7538 va_arg()s as it seems to require it nowadays. I guess, if SILC
7539 is compiled with older va_arg() the new code should work anyway.
7541 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7543 * Splitted core library. Core library (lib/silccore) includes
7544 now only SILC protocol specific core (and common) components.
7545 Created new utility library (lib/silcutil) that includes more
7546 generic purpose stuff. The stuff for util library was taken
7547 from the old core library. This was minor and easy split.
7549 * Created SILC Client Library (lib/silcclient) that includes
7550 implementation of the SILC client without user interface. This
7551 was major move from silc/ directory. The code has been changed
7552 so that it is transparent towards the user interface. The
7553 silc/ directory includes now the same user interface as before
7554 and it uses the new client library. Read lib/silcclient/README.
7555 Basicly, the client library performs everything else related
7556 to SILC except user interface handling. Also, configuration
7557 files are considered to be part of user interface and library
7558 does not handle them.
7560 This change also changed a lot of structures, function naming etc.
7561 Most important change was that SilcClientWindow object was
7562 renamed to SilcClientConnection in the client library. Created
7563 also new file lib/silcclient/ops.h. Also added new files
7564 silc/local_command.[ch] and silc/client_ops.[ch].
7566 All these changes were made to make it easier for user interface
7567 designers to create what ever user interface for the SILC client
7570 It is also expected that the server will be moved to lib
7571 directory as well and SILC Server Library will be created;
7572 sometimes in the future.
7574 * Removed Local commands from lib/silccore/silccommand.h as
7575 they are application specific and new client library does not
7576 handle any of those anymore.
7578 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7579 old client implementation in silc/.
7581 * Added support for callback functions in SILC_LOG_* macros.
7582 Application can now set its own callbacks that will be called
7583 instead of using the default functions that will always print
7584 the debug messages to stderr (or stdout). Also, debugging can
7585 now be disabled by setting silc_debug to FALSE and re-enabled by
7586 setting it to TRUE. Note, that logging will still work even
7587 if debugging is disabled.
7589 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7590 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7591 silc_log_reset_debug_callbacks.
7593 * To enable debugging in silc client one must give now -d
7594 option on command line.
7596 * Changed silc_schedule_init to automatically allocate task queues
7597 if they are not allocated before calling it.
7599 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Added GMP 3.1 into math library.
7603 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7605 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7606 a channel in SILC network. The packet is used by servers and
7607 routers to notify other routers that user has left a channel.
7608 This little feature was missing until now. Added the feature
7609 to protocol specification as well.
7611 Added functions: silc_server_send_remove_channel_user and
7612 silc_server_remove_channel_user into server.[ch].
7614 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7615 lib/silccore/silcpacket.h. However, they are not implemented
7618 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7620 * Fixed joining to a channel and sending channel messages
7621 between server and router. The channel message sending should
7622 now work inside a cell.
7624 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Fixed the private message sending between server and router.
7627 The private message sending should now work inside a cell.
7629 * Added silc_server_replace_id into server.[ch] to replace
7630 existing ID in the SILC network.
7632 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7633 and silc_idlist_replace_server_id into idlist.[ch] in server.
7635 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7637 * Fixed the server to server connections. Server can again now
7638 connect to router. Router to router connections probably does
7641 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7643 * Added dynamic protocol registering support. Now protocols can
7644 registered and unregistered on the fly. Patch by cras.
7646 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * Added lib/contrib directory to hold routines that some platforms
7649 don't have but are needed by SILC.
7651 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7652 into lin/contrib to provide getopt() and getopt_long() for
7653 those who don't have it.
7655 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7657 * Added AWAY command to client. When away message is set and
7658 client receives a private message packet the client automatically
7659 replies to the sender with the away message.
7661 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7662 bug seemed to be the cause of recent problems when compiling
7665 * Added version detection support to SKE protocol specification
7666 and added the new changes to the SKE implementation as well.
7667 There were other minor changes in the SKE protocol as well.
7669 Many changes in lib/silcske/silcske.[ch] and in
7670 lib/silcske/payload.[ch].
7672 * Added ^U functionality, clear input line. Patch from cras.
7674 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7676 * Mainly small bugfixes on core library. Fixed some debugging
7677 logging and buffer overflow in silclog.c.
7679 * Updated config.sub and config.guess on the distribution tree.
7681 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7683 * Added command lagging support in server. Client may execute
7684 commands now only once in two seconds.
7686 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7688 * Optimized packet reception. MAC computation and checking is now
7689 also more optimized. A lot previously duplicated code is now
7690 used as generic by both client and server.
7692 * Fixed key pair generation in clientutil.c
7694 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Added into lib/silccore/silcbufutil.[ch] new function;
7697 silc_buffer_realloc.
7699 * Moved generic packet sending/encryption functions to
7700 lib/silccore/silcpacket.[ch] from client and server. Some
7701 rewriting of the functions.
7703 * Moved all generic packet reception/decryption functions to
7704 lib/silccore/silcpacket.[ch] from client and server. The
7705 packet processing is now much cleaner in both client and server.
7706 These were major changes in both client and server.
7708 * Created many common functions in server to do packet sending.
7709 Previously code were duplicated a lot, this has been removed
7712 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7714 * Rewrote major parts of the ID cache system. Don't know
7715 whether it is better now or not but at least the API is more
7718 * Major rewrite on ID cache stuff on client because of the ID
7719 cache API changes. Added idlist.c to client.
7721 * Also major rewrite on ID cache stuff on server as well.
7722 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7723 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7724 in hand, instead they are all put into the ID cache system now.
7725 All server_idlist_* routines uses ID cache now instead of
7726 traversing its own lists (those lists does not exist anymore).
7727 SilcIDList though still exists. Also, SilcXXXEntry's are
7730 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7732 * Finally made the SKE implementation compliant to the protocol
7733 specification. All mp integers are now binary encoded as
7734 opposed being HEX encoded.
7736 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7739 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7740 functions: silc_[encode/decode]_pem. Also added function
7741 silc_encode_pem_file to PEM encode with newlines ('\n') for
7744 * SILC public keys are now encoded either PEM or binary. Same
7745 option is for private keys as well. By default private keys
7746 are binary encoded and public keys PEM encoded. Silly HEX
7747 encoding were removed.
7749 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7750 function to create fingerprints.
7752 * Fixed a bug in SHA1; does not change the original data anymore.
7754 * Partly implemented INFO command on client and server side.
7755 Fixed CLEAR command. Changes to SERVER command; show current
7756 server(s) when giving command without arguments. Added
7757 VERSION command to client.
7759 * Added check to server that unregistered connections cannot
7760 execute commands (unless it is specificly allowed).
7762 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Fixed screen refresh.
7766 * Fixed channel joining bug from client. On some circumstances
7767 client tried to join to a channel it had already joined.
7769 * Added public key verification process into client's protocol.c.
7770 The client now verifies the public key from user and saves
7771 it into ~./silc/serverkeys/ directory.
7773 Added into: clientutil.[ch]: silc_client_verify_server_key.
7775 * Changed SKE protocol's silc_ske_initiator_finish function
7776 to accept callback function that verifies the received public
7777 key. Removed old silc_ske_verify_public_key function.
7779 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7781 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7782 silc_pkcs_private_key[_data]_set.
7784 * Made the password and public authentication more cleaner in
7785 server's protocol.c.
7787 * Removed historic and obsolete protocol `channel_auth' from
7788 both client and server.
7790 * Removed wrong way of sending command status messages from
7791 server to client in server's command.c. The old way violated
7792 protocol specification.
7794 Changes to silccore/silccommand.[ch]: removed
7795 silc_command_encode_status_payload -> not needed anymore,
7796 changed silc_command_encode_payload_va to accept extra
7797 argument on variable argument list. The argument type must
7798 now be provided to the function. Also, added new function:
7799 silc_command_encode_reply_payload_va which is same as
7800 normal command_encode_payload_va except command status type
7801 is provided as extra argument.
7803 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7805 * Added ~./silc directory handling. The directory includes the
7806 public and private keys for the client.
7808 Added silc_client_check_silc_dir, silc_client_create_identifier
7809 and silc_client_load_keys.
7811 * Implemented SILC protocol compliant public key. Added public
7812 and private key saving to and loading from files.
7814 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7815 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7816 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7817 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7818 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7820 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7821 silc_pkcs_load_[public/private]_key.
7823 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Added silc_server_get_route (route.[ch]) to get connection
7826 data for the fastest route for given ID.
7828 * Implemented INVITE command on client and server. The command
7829 were re-defined in the SILC Protocol Specification and the
7830 implementation now complies with the specification.
7832 * Implemented PING command on client and server.
7834 * Implemented NAMES command on client and server. The server side
7835 supports currently only normal server not router server yet.
7836 Some changes to NAMES definition in SILC protocol specification.
7838 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * Implemented LEAVE command on client and server.
7842 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7843 again. This change was made to the protocol as well. Server
7844 should not violate the protocol specification anymore.
7846 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7849 was tested. SOCKS4 was not but should work anyway.
