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

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

781 Affected files silcd/serverconfig.[c], server.[c].
783 * Splitted the doc/example_silcd.conf.in. Separated the crypto
784 algorithm parts and created new file silcalgs.conf, that
785 is now included from the example_silcd.conf.in.
787 * Optimized the silc_server_connect_to_router_second to take
788 the connection configuration object from the SilcServerConnection
789 object instead of finding it during the connecting phase.
790 Added the configuration object to SilcServerConnection struct.
791 Affected files silcd/server_internal.h, server.c.

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

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

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

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

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

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

1026 functions. Affected file silcd/server.c.
1028 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1029 which ID was changed. This way the router will send the
1030 user list for the channel again, and server won't be in
1031 desync in some rare circumstances. Affected file is
1032 silcd/packet_receive.c.
1034 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1077 given. Affected files silcd/server.[ch].
1079 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1081 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1083 * Fixed the NICK command to always give the unformatted
1084 nickname to the one giving the NICK command. If unformatted
1085 nickname is cached already it will be formatted and the
1086 local entry will always get the unformatted nickname.
1087 Affected file lib/silcclient/idlist.c.
1089 * Fixed some double frees from client library commands.
1090 Affected file is lib/silcclient/command.c.
1092 * Fixed CUMODE command in server to assure that no one can
1093 change founder's mode than the founder itself, there was a
1094 little bug. Affected file silcd/command.c.
1096 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Removed the SilcClientCommandDestructor from the client
1099 libary, it is not needed anymore. Affected files are
1100 lib/silcclient/silcapi.h, command[_reply].[ch],
1101 client_notify, idlist.c.
1103 * Fixed GETKEY command to first resolve client, and then
1104 resolve the server only if the client was not found, instead
1105 of resolving both at the same time. Affected file is
1106 lib/silcclient/command.c.
1108 * Added silc_client_start_key_exchange_cb and lookup the
1109 remote hostname and IP address before starting the key
1110 exchange with server. The affected file is
1111 lib/silcclient/client.c.
1113 * The server's public key is now saved using the IP address
1114 of the server and not the servername for the filename.
1115 The hostname public key filename is checked as an fall back
1116 method if the IP address based filename is not found.
1118 Fixed the GETKEY command to save the fetched server key
1119 in correct filename.
1121 Print the remote server's hostname now when new key is
1122 received during connection process. Affected file is
1123 irssi/src/silc/core/client_ops.c.
1125 * Return always our own public key to the client if it asks
1126 for it with GETKEY command. Affected file silcd/command.c.
1128 * Removed the use_auto_addr variable from default config
1129 file since it was in wrong section. Affected file is
1132 * Fixed TOPIC_CHANGE notification to not route it when it
1133 was sent using silc_server_send_notify_to_channel function.
1134 Affected file silcd/command.c.
1136 * Fixed silc_server_send_notify_kicked to send the kicker's
1137 Client ID also, it was missing. Affected files are
1138 silcd/command.c, silcd/packet_send.[ch].
1140 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1142 * Do not save client history information in SERVER_SIGNOFF.
1143 Fixes the bug in normal server that it does not detect
1144 the client becoming valid after the server becomes back
1145 online. Affected file silcd/server_util.c.
1147 * Added `sock_error' field into the SilcSocketConnection
1148 context. When error occurs during socket operation (read
1149 or write) the error is saved. Added also new function
1150 silc_socket_get_error to return human readable socket error
1151 message. Affected files are lib/silcutil/silcsockconn.[ch],
1152 lib/silcutil/unix/silcunixsockconn.c, and
1153 lib/silcutil/win32/silcwin32sockconn.c.
1155 * The server now prints the socket error message in the
1156 signoff for client. Affected file silcd/server.c.
1158 * Fixed the `created' channel information sending from router
1159 to server in JOIN command. Checks now whether the channel
1160 really was created or not and set it according that.
1162 Fixed the JOIN command to use the client entry's current
1163 ID during the joining procedure instead of the one it sent
1164 in the command (it is checked though), since it can change
1165 between the packet processing and command processing, and
1166 would just case unnecessary pain in the client end. Affected
1167 file silcd/command.c.
1169 * Fixed a channel key payload sending to use correct channel
1170 ID when the server was forced to change the channel's ID by
1171 router. Router sent the key payload with the old Channel ID.
1172 Affected file silcd/packet_receive.c.
1174 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1176 * Call silc_server_save_channel_key only if the key payload
1177 was provided in the JOIN command's command reply. Affected
1178 file silcd/command_reply.c.
1180 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1182 * Fixed silc_mp_sizeinbase to return the value correctly with
1183 MPI. Affected file lib/silcmath/mp_mpi.c.
1185 * Fixed the stop_server signal to correctly stop the scheduler
1186 and gracefully stop the server when SIGTERM or SIGINT signals
1187 are received. Affected file silcd/silcd.c.
1189 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1191 * Simple handling of TERM and HUP signals. Also added some log
1192 flushing call around. Affected file is
1195 * Fixed small bugs in silclog.c. Now buffering output will take
1196 effect after 10 seconds since startup: This will ensure that
1197 no important startup messages are lost. Also output redirection
1198 will preserve original format ([Date] [Type] message).
1199 Affected file is lib/silcutil/silclog.c.
1201 * Added two options to the config file, in the logging section:
1202 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1203 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1205 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1207 * Do not print the warning about log files not being initialized
1208 more than once to avoid excess logging. Affected file is
1209 lib/silcutil/silclog.c.
1211 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1212 the SIM copying in make install in Makefile.am.pre.
1214 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1216 * Rewritten silclog APIs. Globally interesting changes follows:
1217 silc_log_set_files() changed to silc_log_set_file().
1218 silc_log_set_callbacks() changed to silc_log_set_callback().
1219 ROBOdoc documented silclog header file.
1220 SilcLogCb now returns bool to wether inihibit the default
1221 handler or not (to keep the old behaviour return always TRUE).
1222 The new APIs should also fix the problem of the
1223 silcd_error.log file that was written in the current directory.
1226 Log files streams will remain opened after silc_log_set_file()
1227 call, means less CPU usage notably on high traffic servers.
1228 File streams are now full buffered, and flushed to the disk
1229 every 5 minutes, lesses HD activity and CPU usage.
1230 Messages can be redirected, allowing admins to configure
1231 one single logfile for all server messages.
1232 the silc_log_quick global variable to activate fast-logging.
1233 Affected files lib/silcutil/silclog.[ch]
1235 * Changed some code to conform new silclog APIs. Affected
1236 files are doc/example_silcd.conf.in, silcd/server.c
1237 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1240 * Fixed a memory leak that could occur in some situations.
1241 Affected file silcd/serverconfig.c.
1243 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1245 * Added the silc_client_del_client to remove the client from
1246 all channels as well. Affected file lib/silcclient/idlist.c.
1248 * Fixed the client library to correctly remove the client
1249 from all channels when the client entry is being destroyed.
1250 Affected file lib/silcclient/client_notify.c, command.c.
1252 * Added auto-nicking support to the client library. If the
1253 applicatio now sets client->nickname it will be sent to the
1254 server after connecting by the library. This way for example
1255 SILCNICK (or IRCNICK) environment variables will have effect
1256 and always change the nickname automatically to whatever
1257 it is wanted. Affected file lib/silcclient/client.[ch].
1259 * Renamed silc_server_command_bad_chars to the
1260 silc_server_name_bad_chars and moved it to the
1261 silcd/server_util.[ch]. Added also new function
1262 silc_server_name_modify_bad to return nickname that
1263 includes bad characters as new nickname without those
1264 bad characters. This check and modify is now used in
1265 silc_server_new_client when the username is initially set
1266 as nickname, so it must be checked to be valid nickname.
1267 Affected file silcd/packet_receive.c.
1269 * The nickname length is now taken from the packet for real
1270 and not trusted to strlen() since it clearly can return
1271 wrong length for nickname including bad characters. This
1272 also applies to channel names. Affected file silcd/command.c.
1274 * Removed the lib/silcsilm/modules directory. Modules are now
1275 compiled into the lib/silcsim. Fixed the copying of the
1276 modules to follow symbolic links in Makefile.am.pre.
1278 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1280 * Fixed silc_string_regexify list creation. Fixes bugs with
1281 BAN and INVITE commands in server. The affected file is
1282 lib/silcutil/unix/silcunixutil.c.
1284 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Removed the command destructor entirely from the server's
1287 command and command reply routines. It is not needed, and
1288 its usage was buggy and caused crashes. Affected files are
1289 silcd/command[_reply].[ch].
1291 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Cancel protocol and NULL sock->protocol if timeout
1294 occurred during protocol. Affected file silcd/server.c.
1296 * Cancel protocol timeouts always before calling the final
1297 callback, to assure that after final callback is called
1298 no other state will be called for the protocol anymore.
1299 Affected file silcd/protocol.c.
1301 * Print error log if incoming connection configuration could
1302 not be found. Affected file silcd/server.c.
1304 * Fixed JOIN command to correctly save the founder mode
1305 to the client on normal SILC server, when the channel
1306 was created by the router. Affected file silcd/command.c.
1308 * Fixed LIST command (hopefully) to send correct reply
1309 packets. Affected file silcd/command.c.
1311 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * The silc_packet_receive_process now returns FALSE if the
1314 read data was invalid packet, and TRUE if it was ok.
1316 The server now checks that if unauthenticated connection
1317 sends data and its processing fails the server will close
1318 the connection since it could be a malicious flooder.
1320 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1322 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1324 * Make sure the warning about error opening a log file is
1325 printed only once and not everytime it fails (produces
1326 too much useless log). Affected file lib/silcutil/silclog.c.
1328 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1330 * Made the silc_server_daemonise() function more readable.
1331 Affected file silcd/server.c.
1333 * Pid file is now optional, the user may comment it out from
1334 the config file. Removed define SILC_SERVER_PID_FILE, we
1335 don't need a default any longer. Affected file
1336 configure.in.pre, lib/Makefile.am.pre.
1338 * Make some use of the pid file. The server now dies at startup
1339 if it detects a valid pid file on his path. The server would
1340 die anyway in this circumstance, because of the bind() failure.
1341 Affected file silcd/silcd.c.
1343 * No longer compiling lib/dotconf.
1345 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * Fixed JOIN command parsing not to crash. Affected file
1348 lib/silcclient/command.c.
1350 * Fied the NICK_CHANGE notify to add the new client entry
1351 even it is resolved. This removes an <[unknown]> nick
1352 thingy bug in the client. Affected file is
1353 lib/silcclient/client_notify.c.
1355 * Do not try to allocate 0 bytes (efence does not like it)
1356 in lib/silccore/silccomand.c when encoding payload.
1358 * Do not take IRCNICK as nickname in Irssi SILC client since
1359 it is not possible to set nickname before hand connecting
1360 the server (TODO has an entry about adding auto-nicking
1363 * Changed the silc_server_command_pending to check whether
1364 there already exists an pending entry with the specified
1365 command, command identifier and pending callback. This is
1366 to fix IDENTIFY and WHOIS related crashes that may register
1367 multiple pending commands with same identifier. Affected
1368 file silcd/command.c.
1370 * Fixed the server to reconnect to the router even if it
1371 was already reconnecting and EOF was received. This to
1372 fix a possibility that the server wouldn't ever try to
1373 auto-reconnect to the router. Affected file silcd/server.c.
1375 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Fixed the server's password authentication to use the
1378 length of the locally saved password, and not the one
1379 sent in the packet. Affected file silcd/protocol.c.
1381 * Fixed same password authentication problem in the
1382 Authentication Payload handling routines in
1383 lib/silccore/silcauth.c.
1385 * Yet another password authentication problem fixed with
1386 channel password handling in silcd/command.c.
1388 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * If first character of string in silc_parse_userfqdn is '@'
1391 then do not parse it. Affected file is
1392 lib/silcutil/silcutil.c.
1394 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Fixed minor bug in IDENTIFY command reply sending, which
1397 caused various weird problems during JOIN when it was
1398 resolving names for users. Affected file silcd/command.c.
1400 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Fixed the IDENTIFY command reply sending to chech better valid
1403 clients. It was possible to send incomplete list of replies.
1404 Affected file silcd/command.c.
1406 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Added silc_client_command[s]_[un]register functions now to
1409 dynamically register the commands in client library. Removed
1410 the static table of commands. This allows the client library
1411 to call commands without causing the application to know about
1412 what commands library has called.
1414 Removed the INFO command reply kludge to detect when the command
1415 was called by library. Now library use its own command reply
1416 function for INFO command.
1418 Added function silc_client_command_call to call a command.
1419 Application can use it to call command, not access the structure
1422 Now all commands that are sent by the client library (not
1423 explicitly sent by application) use own command reply functions.
1425 Affected files around lib/silcclient/ and in
1426 irssi/src/silc/core/.
1428 * Fixed the WHOIS command reply sending to chech better valid
1429 clients. It was possible to send incomplete list of replies.
1431 Fixed the WHOIS and IDENTIFY to send the request to router
1432 if normal server did not do it and did not find any results.
1434 Affected file silcd/command.c.
1436 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Moved the internal data from SilcClient context into its
1439 own file, not accesible to application. Affected files
1440 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1441 and other files in client library.
1443 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Added doc/examples installation target in Makefile.am.pre.
1448 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1451 commands the found client entry will be removed from the
1452 cache, after notifying application about the error. Affected
1453 file lib/silcclient/command_reply.c.
1455 * Changed the /MSG to check for exact nickname user gave, and
1456 not let `nick' match `nick@host' if it is only one found. Now,
1457 user must type the exact nickname (like nick@host2) even if
1458 there are no more than one same nicks found. This is to avoid
1459 a possibility of sending nickname to wrong nickname since
1460 `nick' could match `nick@host'. Affected file is
1461 irssi/src/core/silc-servers.c.
1463 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * Do not print "you are now server operator" or similar when
1466 giving /away command. Affected files are
1467 irssi/src/silc/core/client_ops.c, silc-servers.h.
1469 * Made the silc_server_command_pending_error_check to send
1470 the same command reply payload it received back to the
1471 original sender of the command. This way all arguments
1472 that was received by the server will be received by the
1473 client too. Affected file silcd/command.c.
1475 * Added the silc_idcache_add to return the created cache entry
1476 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1478 * Add global clients to expire if they are not on any channel.
1479 This is because normal server will never know if they signoff
1480 if they are not on any channel. The cache expiry will take
1481 case of these entries. This is done by normal servers only.
1482 The affected files are silcd/command_reply.c,
1483 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1485 * If server receives invalid ID notification for WHOIS or
1486 IDENTIFY and the ID exists in the lists, it is removed.
1487 Affected file silcd/command_reply.c.
1489 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1490 in client then client entry that it matches is searched and
1491 the nickname is printed on the screen for user. Affected
1492 file irssi/src/silc/core/client_ops.c.
1494 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Use cache entry expire time in the LIST command reply to
1497 purge old entries from the cache after the LIST command
1498 reply has been received. This way we don't have non-existent
1499 entries in the cache for too long. Affected file is
1500 silcd/command_reply.c.
1502 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * If we are normal server, and we've not resolved client info
1505 in WHOIS or IDENTIFY from router, and it is global client,
1506 we'll check whether it is on some channel. If it is not
1507 then we cannot be sure about its validity and will resolve it
1508 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1509 file silcd/command.c.
1511 * Search channel by name (if possible) rather than by ID
1512 in IDENTIFY command's command reply. Affected file is
1513 silcd/command_reply.c.
1515 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1518 Updated specs and implemented it. Affected file silcd/command.c,
1519 silcd/packet_send.c and silcd/packet_receive.c.
1521 * Implemented the <founder auth> payload handling in the JOIN
1522 command. If provided all conditions for channel joining
1523 except requirement to provide correct passphrase can be
1524 overrided by the channel founder. Updated the protocol specs.
1525 Affected file silcd/command.c.
1527 Added support for founder auth in JOIN command in client
1528 library. Fixed the parsing of the JOIN command now to support
1529 all options as they should be. The affected file is
1530 lib/silcclient/command.c.
1532 * Optimized the WHOIS and IDENTIFY commands to send the request
1533 to router only if it includes nicknames or other names. If
1534 they include only IDs then check the local cache first before
1535 routing. Affected file is silcd/command.c.
1537 * Added channels topic announcements. Affected file is
1538 silcd/packet_receive.c and silcd/server.c.
1540 * Fixed the silc_server_send_notify_topic_set to really destine
1541 the packet to channel. Affected file silcd/packet_send.c.
1543 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1544 library. Affected file lib/silcclient/client_notify.c.
1546 * Added UMODE announcements. Affected file silcd/server.c.
1548 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Memory leak fixes in:
1552 lib/silcutil/silcsockconn.c
1553 lib/silcske/silcske.c
1554 lib/silcske/groups.c
1556 lib/silccrypt/silcpkcs.c
1557 lib/silccore/silccommand.c
1558 lib/silccore/silcidcache.c
1563 * ROBOdoc documented the lib/silcske/groups.h file and a
1564 bit changed the interface for better.
1566 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1568 * Update the client entry context in the ID cache after
1569 nick change. Affected file lib/silcclient/command.c.
1570 Fixes the CUMODE command when regaining founder privileges,
1571 and a little WHOIS problem.
1573 * Fixed silc_net_gethostbyname to correctly call the
1574 inet_ntop. Affected file lib/silcutil/silcnet.c.
1576 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1578 * Added IPv6 support checking to the configure.in.pre, added
1579 also --enable-ipv6 option to override the check. Affected
1580 file configure.in.pre.
1582 * The silc_thread_create now calls the start function
1583 directly if threads support is not compiled in. Removes
1584 ugly #ifdef's from generic code. Affected files are
1585 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1587 * Added silc_net_gethostby[name/addr]_async to asynchronously
1588 resolve. Affected files are lib/silcutil/silcnet.[ch].
1590 * Added support for rendering IPv6 based server, client and
1591 channel IDs. Affected file lib/silcutil/silcutil.c.
1593 * Added support for creating IPv6 based server IDs. Affected
1594 file is silcd/serverid.c.
1596 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1598 * Added silc_net_gethostby[addr/name] into the
1599 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1600 routines. Added silc_net_is_ip[4/6]. Affected file is
1601 lib/silcutil/unix/silcunixnet.c. All routines that take
1602 address as argument now supports both IPv4 and IPv6 addresses.
1604 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1606 * Fixed LIST command reply sending in server. Affected file
1609 * Server now sends the kicker's client ID in the KICK notify
1610 to the kicked client. Affected file silcd/command.c.
1612 * The client library now parses the kickers client ID and
1613 UI displays it. Affected files lib/silcclient/client_notify.c
1614 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1616 * Made all payload parsing function prototypes consistent.
1617 They all take now const unsigned char * and uint32 pair as
1618 the payload data instead of SilcBuffer. Changes all around
1619 the source tree. Other unsigned char* -> const unsigned char*
1620 changes around the tree as well.
1622 * Optimized SFTP client and server packet sending not to
1623 allocate new buffer for each packet but to recycle the
1624 first allocated buffer. Affected files are
1625 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1627 * Optimized the SFTP client to use SilcList instead of
1628 SilcDList for requests, because it is faster. Affected file
1629 is lib/silcsftp/sftp_client.c.
1631 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1632 into lib/silccore/silcid.[ch].
1634 Renamed silcpayload.[ch] into silcargument.[ch].
1636 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * If client entry is deleted with active key agreement
1639 session, abort the session.
1641 The silc_client_abort_key_agreement now calls the completion
1642 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1644 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1647 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Don't use __restrict in older GCC's. Affected file is
1650 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1652 * silc_net_localhost now attempts to reverse lookup the
1653 IP/hostname. Affected file lib/silcutil/silcnet.c.
1655 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1656 command. It can be used to gain founder privileges at
1657 the same time when joining the channel.
1659 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1660 kicker's client ID as well. Updated protocol specs.
1662 Defined that the server must send SILC_COMMAND_IDENTIFY
1663 command reply with error status to client who sent
1664 private message with invalid client ID.
1666 Updated the protocol specification.
1668 * Added silc_server_send_command_reply to send any
1669 command reply. Affected file silcd/packet_send.[ch].
1671 * Added silc_id_payload_encode_data to encode ID payload
1672 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1674 * The server now send IDENTIFY command reply with error
1675 status if client ID in private message is invalid. Affected
1676 file silcd/packet_receive.c.
1678 * Save the server key file with server's IP address in
1679 the filename instead of hostname. The affected file is
1680 irssi/src/silc/core/client_ops.c.
1682 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1684 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1687 * Added libtool support for compiling shared objects in
1688 lib/silcsim. Affected file configure.in.pre and
1689 lib/silcsim/Makefile.am. Original patch by cras.
1691 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Pid file configuration, and server's config file fixes
1694 patch by toma. Updated CREDITS file.
1696 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1698 * Fixed silc_client_channel_message to not try to decrypt
1699 the message twice if it resolved the destination client
1700 information. This could cause of dropping one channel
1701 message. Affected file lib/silcclient/client_channel.c.
1703 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1706 lib/silcclient/client.c. This function is used when the SILC
1707 Client is run under some other scheduler, or event loop or
1708 main loop. On GUI applications, for example this may be
1709 desired to used to run the client under the GUI application's
1710 main loop. Typically the GUI application would register an
1711 idle task that calls this function multiple times in a second
1712 to quickly process the SILC specific data.
1714 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1716 * Fixed silc_server_drop() for dropping the supplementary
1717 groups as well, this could cause a security hole on some
1720 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1725 * Write PID file after dropping privileges. Added -F option
1726 to run server on foreground. A patch by debolaz.
1727 Affected files silcd/server.c, silcd/silcd.c.
1729 * Fixed MOTD to return the MOTD file server name. Affected
1730 file silcd/command.c.
1732 * Added INFO command reply handling to the Irssi SILC Client.
1733 Affected file irssi/src/silc/core/client_ops.c.
1735 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Fixed the silc_idcache_list_* routines to really support
1738 the dynamic list. Fixes a crash. Affected file is
1739 lib/silccore/silcidcache.c.
1741 * Fixed the LIST command reply to really call LIST command's
1742 pending callbacks. Affected file silcd/command_reply.c.
1744 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Update conn->local_entry->nickname after giving NICK
1747 command. Affected file lib/silcclient/command.c.
1749 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1751 * Added the [pid] option to the silcd configuration file
1753 Affected files: serverconfig.[ch] and silcd.c
1755 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * Save fingerprint in WHOIS command reply in server.
1758 Affected file silcd/command_reply.c.
1760 * Fixed NICK commands pending callback registration.
1761 Affected file lib/silcclient/command.c.
1763 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Use ++server->cmd_ident when sending commands in server,
1766 instead of random number. Affected file silcd/command.c.
1768 * Fixed GETKEY command reply to call actually GETKEY pending
1769 command callbacks. Affected file silcd/command_reply.c.
1771 * A bit stricter check for nicknames. Check for same nickname
1772 in NICK command also. Affected file silcd/command.c.
1774 * Do not call INFO command everytime client ID changes, only
1775 during first connecting. Affected file lib/silcclient/client.c.
1777 * Set the new nickname only after successful command reply for
1778 NICK command is returned by server. Affected file
1779 lib/silcclient/command.c.
1781 * Remove nicknames from nicklist during server_signoff notify.
1782 Should fix /NAMES bit more. The affected file is
1783 irssi/src/silc/core/silc-channels.c.
1785 * Added `fingerprint' field to the SilcIDListData in the
1786 silcd/idlist.h to hold the fingerprint of the client's
1789 Send the fingerprint of the client's public key in WHOIS
1792 Affected files silcd/command.c, and silcd/idlist.[ch].
1794 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1795 create fingerprint from given data.
1797 * Show the fingerprint of the client's public key in WHOIS.
1798 Affected files irssi/src/module-formats.[ch] and
1799 irssi/src/silc/core/client_ops.c.
1801 * Format the multiple same nicknames also during JOIN and
1802 NICK_CHANGE notifys. Affected file is
1803 lib/silcclient/client_notify.c.
1805 * Do not print error on screen for invalid private message
1806 payload since it can come if someone is sending private
1807 messages with wrong key. Affected file
1808 lib/silccore/silcprivate.c.
1810 * Fixed multiple concurrent /PING crash. Affected file
1811 lib/silcclient/command.c.
1813 * Changed the wrong ID encoding. All IP addresses must be
1814 in MSB first order in encoded format. They were encoded
1815 wrong and was in LSB format. Affected files are
1816 silcd/serverid.c, lib/silcutil/silcutil.c.
1818 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1820 * Call the `connect' client operation through the scheduler
1821 in case of error. Affected file lib/silcclient/client.c.
1823 * Call the `failure' client operation even if the error
1824 occurred locally during a protocol. Affected file is
1825 lib/silcclient/protocol.c.
1827 * Added support of sending LIST command to router from normal
1828 server. This way normal server can get list of all channels
1829 in the network too. Fixed the channel list sending in the
1830 server too. Affected files are silcd/command.c, and
1831 silcd/command_reply.[ch].
1833 * Added silc_server_update_channels_by_server and
1834 silc_server_remove_channels_by_server. They are used during
1835 disconnection of primary router and in backup router protocol.
1836 Affected file silcd/server_util.[ch], silcd/server.c and
1837 silcd/server_backup.c.
1839 * Fixed channel adding to global list in IDENTIFY command
1840 reply in server. Affected file silcd/command_reply.c.
1842 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * If the incoming packet type is REKEY or REKEY_DONE process
1845 that packet always synchronously. Fixes yet another MAC
1846 failed error on slow (dialup) connections. Affected file
1847 lib/silcclient/client.c and silcd/server.c.
1849 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Call check_version SKE callback for initiator too. Affected
1852 file lib/silcske/silcske.c.
1854 * Implemented fix for security hole found in the SKE that was
1855 fixed in the specification few days back; the initiator's
1856 public key is now added to the HASH value computation.
1857 Added backwards support for the old way of doing it too, for
1858 old clients and old servers. Affected file is
1859 lib/silcske/silcske.c.
1861 * Enabled mutual authentication by default in SKE. If initiator
1862 is not providing mutual authentication the responder will
1863 force it. This will provide the proof of posession of the
1864 private key for responder. The affected files are
1865 lib/silcclient/protocol.c and silcd/protocol.c.
1867 * Do not cache anymore the server's public key during SKE.
1868 We do mutual authentication so the proof of posession of
1869 private key is done, and if the server is authenticated in
1870 conn auth protocol with public key we must have the public
1871 key already. Affected file silcd/protocol.c.
1873 * Added new global debug variable: silc_debug_hexdump. If
1874 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1875 file lib/silcutil/silclog.[ch].
1877 * Fixed compilation warning due to char * -> const char *.
1878 Affected files lib/silcutil/silcnet.h, and
1879 lib/silccore/silcauth.[ch].
1881 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Fixed CMODE command when new channel key was created. If
1884 the creation failed the old key was removed. Next time giving
1885 same command would crash the server since the old key was
1886 freed already. Affected file silcd/command.c.
1888 * Fixed the silc_server_announce_get_channels to not crash
1889 on reconnect. Affected file silcd/server.c.
1891 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Added silc_log_set_debug_string function to set a regex
1894 string to match for debug output. Only the function names,
1895 or filenames matching the given debug string is actually
1896 printed. This way it is possible to filter out those debug
1897 strings that user is not interested in.
1899 Fixed a bug in silc_string_regexify.
1901 Affected files lib/silcutil/silclog.[ch], and
1902 lib/silcutil/unix/silcunixutil.c.
1904 * Changed the -d options in both server and Irssi SILC client
1905 to take the debug string as argument. Affected files
1906 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1908 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Added silc_hash_babbleprint to create a Bubble Babble
1911 Encoded fingerprint. The encoding is developed by Antti
1912 Huima (draft-huima-babble-01.txt), and it creates human
1913 readable strings out of binary data. Affected file
1914 lib/silccrypt/silchash.[ch].
1916 * Print the babble print now in addition of fingerprint as well
1917 in Irssi SILC client. Affected files are
1918 irssi/src/fe-common/silc/module-formats.[ch],
1919 irssi/src/fe-common/silc/core/client_ops.c.
1921 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * Fixed a security problem found in SKE. The initiator's
1924 public key too is now added to the HASH hash value creation
1925 which is signed by the responder to create the SIGN value.
1926 This will prevent anyone in the middle to lie to the responder
1927 about the initiator's public key. If this is done now, the
1928 man in the middle will get caught. Updated the protocol
1931 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Better installation directory handling. Configure module
1934 paths and other paths automatically to example_silc* files
1935 in doc/. A patch by toma.
1937 * Fixed compiler warning from MPI library, and from SILC RNG.
1940 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1941 It can be configured with ./configure. A patch by toma.
1943 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Find correct make to use in prepare-clean. A patch by
1946 toma. Affected file prepare-clean.
1948 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1950 * Added irssi variables use_auto_addr, auto_bind_ip,
1951 auto_bind_port and auto_public_ip.
1953 * Changed the interface for silc_client_send_key_agreement
1954 in lib/silcclient/silcapi.h
1958 irssi/src/silc/core/silc-core.c
1960 lib/silcclient/silcapi.h
1961 irssi/src/silc/core/silc-channels.c
1962 lib/silcclient/client_keyagr.c
1965 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Added silc_pkcs_public_key_compare to compare two
1968 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1970 * Check that the client who set the founder mode on the
1971 channel is the same client that is giving the founder
1972 mode to itself. It is done by comparing the saved public
1973 key (it is saved even in the authentication is passphrase).
1974 Affected file silcd/command.c.
1976 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Do not process packet for disconnected socket connection.
1979 Affected file lib/silccore/silcpacket.c.
1981 * Process the DISCONNECT packet through scheduler in the
1982 client library. Affected file lib/silcclient/client.c.
1984 * Fixed the silc_client_packet_parse to not to increase
1985 the packet sequence number if the conn->sock and the
1986 current socket connection is not same. This can happen
1987 for example during key agreement when the conn includes
1988 multiple socket connections (listeners). Affected file
1989 lib/silcclient/client.c.
1991 * The sender of the file transfer request now provides also
1992 the pointer (listener) for the key exchange protocol. If
1993 the listener cannot be created then it sends empty key
1994 agreement and lets the receiver provide the listener.
1996 Added `local_ip' and `local_port' arguments to the
1997 silc_client_file_send. If they are provided they are used,
1998 if not then it will attempt to find local IP address, if
1999 not found or bind fails then the remote client will provide
2002 Affected files are lib/silcclient/client_ftp.c and
2003 lib/silcclient/silcapi.h.
2005 * Extended the FILE SEND command to support defining the
2006 local IP and port for key exchange listener. They are
2007 optional. Affected file irssi/src/silc/core/silc-servers.c.
2009 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Defined to WHOIS command reply the sending of fingerprint
2012 of the client's public key (if the proof of posession of the
2013 corresponding private key is verified by the server).
2014 Updated to the protocol specification.
2016 * Added support of receiving the client's public key's
2017 fingerprint in command reply in client library. Affected
2018 file is lib/silcclient/command_reply.c, and
2019 lib/silcclient/idlist.[ch].
2021 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * Do not send over 128 chars long nickname to the server
2024 in NICK command. Affected file lib/silcclient/command.c.
2026 * Do not send over 256 chars long channel names to the server
2027 in JOIN command. Affected file lib/silcclient/command.c.
2029 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Assure that silc_server_close_connection cannot be called
2032 twice for same socket context. Affected file is
2035 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Send error message to application if opening file for
2038 writing during file transfer fails. Affected file is
2039 lib/silcclient/client_ftp.c.
2041 Remove all file transfer sessions for a client that we're
2042 removing from ID cache.
2044 Affected file is lib/silcclient/client_ftp.c.
2046 * Fixed silc_net_addr2bin to return correct address. Affected
2047 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2049 * Fixed file transfer session removing on signoff notify.
2050 Affected file irssi/src/silc/core/silc-servers.c.
2052 * Added the SilcClientFileError to be returned in the monitor
2053 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2054 Affected file lib/silcclient/silcapi.h.
2056 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2058 * Fixed a crash in silc_client_ftp_free_sessions and
2059 silc_client_ftp_session_free_client. Affected file
2060 lib/silcclient/client_ftp.c.
2062 * Added `disabled' field in the SilcChannelEntry in the server
2063 to indicate if the server entry is disabled. Affected file
2064 silcd/idlist.h, silcd/command[_reply].c.
2066 * SILC server adds now /var/run/silcd.pid everytime it is
2067 started. Affected file silcd/silcd.c.
2069 * Added silc_server_packet_send_clients to send a packet to
2070 the provided table of client entries. Affected file
2071 silcd/packet_send.[ch].
2073 * Fixed a crash in client resolving in client_prvmsg.c in
2074 client library. Affected file lib/silcclient/client_prvmsg.c.
2076 * Do not actually remove the client directly from ID cache
2077 during SERVER_SIGNOFF, but invalidate it. This way we
2078 preserve the WHOWAS info for the client. Affected file
2079 silcd/server_util.c.
2081 * Fixed SERVER_SIGNOFF notify handling in the server. The
2082 server is now able to process incoming SERVER_SIGNOFF notify
2083 for a server that it doesn't even know about. It will remove
2084 the clients provided in the notify. Affected file
2085 silcd/packet_receive.c.
2087 * Check for partial packet in data queue after every packet that
2088 was found from the queue. Return and wait for more data if
2089 there is partial data in queue. Affected file is
2090 lib/silccore/silcpacket.c.
2092 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Added SilcClietFileError enum to indicate error in
2095 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2096 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2097 Affected files lib/silcclient/silcapi.h and
2098 lib/silcclient/client_ftp.c.
2100 * Check that newsize in silc_buffer_realloc is larger than
2101 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2103 * Added better monitor of file transfers. It now monitors
2104 key agreement protocol during the file transfer too. Added
2105 error reporting too. Affected files
2106 irssi/src/silc/core/silc-servers.c,
2107 irssi/src/fe-common/silc/module-formats.[ch].
2109 * Wrote a help file for FILE command.
2111 * Added silc_rng_global_get_byte_fast to get not-so-secure
2112 random data as fast as possible. Random data is read from
2113 /dev/urandom if available and from the SILC RNG if not
2114 available. It is used in padding generation. Affected file
2115 lib/silccrypt/silcrng.[ch].
2117 * All packets in client library are now processed synchronously.
2118 Optimized packet processing a lot. Affected file
2119 lib/silcclient/client.c.
2121 * All server connection packets are processing synchronously
2122 now in server, to optimize packet processing. Affected file
2125 * Include files are installed now only in Toolkit distribution
2126 if make install is given. Affected files: all Makefile.am's.
2128 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Assure that silc_client_notify_by_server_resolve does not
2131 resolve the client information multiple times. If it cannot
2132 be found by the first it cannot be found at all. Affected
2133 file lib/silcclient/client_notify.c.
2135 * Fixed WHOWAS command reply calling. Affected file
2136 lib/silcclient/command_reply.c.
2138 * Removed all references to silc_idlist_get_client from the
2139 Irssi SILC client since that call is internal call used by
2140 the library. The Irssi SILC client will use now client
2141 retrieval functions found in silcapi.h.
2143 * Fixed a bug in resolving nickname info before sending
2144 private message. It used freed memory. Affected file
2145 irssi/src/silc/core/silc-servers.c.
2147 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Assure my_channels statistics cannot go negative in server.
2150 Affected files silcd/server.c, silcd/server_util.c.
2152 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2166 * Added silc_net_localip to return local host's IP address.
2167 Affected file lib/silcutil/silcnet.[ch].
2169 * If key exchange or rekey protocol is active for a connection
2170 parse all packets syncronously since there might be packets
2171 in packet queue that we are not able to process without first
2172 processing packets before them. Affected file silcd/server,
2173 lib/silcclient/client.c.
2175 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2176 whether library should continue processing the packet.
2177 Affected file lib/silccore/silcpacket.h.

2208 lib/silcutil/silcutil.[ch].
2210 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Resolve the client info when received private message or
2213 channel message for a client which nickname we don't know.
2214 Affected files lib/silcclient/client_prvmsg.c and
2215 lib/silcclient/client_channel.c.
2217 * Do not crash in /KEY if client is not connected. Affected
2218 file irssi/src/silc/core/silc-channels.c.

2223 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2224 is incomplete and is being resolved, it won't be resolved
2227 Make sure also that USERS command reply does not resolve
2228 twice information. Affected file is
2229 lib/silcclient/command_reply.c.
2231 Make sure that silc_client_get_clients_by_list does not
2232 resolve twice same information.
2234 * Check for valid client->id in the silc_server_free_client_data.
2235 Affected file silcd/server.c.
2237 * Fixed /GETKEY nick@server not to crash if the server entry
2238 is not found. Affected file lib/silcclient/command.c.
2240 * Fixed the silc_server_check_cmode_rights to check the
2241 requested modes correctly. Affected file silcd/command.c.

2245 * Better checks for non-printable chars in nick added.
2246 Affected file silcd/command.c.
2248 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Call the silc_server_udpate_servers_by_server in the
2251 primary router that comes back online in the backup resuming
2252 protocol. Otherwise it routes packets wrong. Affected file
2253 silcd/server_util.[ch], silcd/server_backup.c.
2255 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2258 lib/silcutil/silcbuffmt.[ch].
2260 * Redefined the SILC packet header to include the padding
2261 length. Affected file lib/silccore/silcpacket.[ch].
2263 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2264 length for maximum padding up to 128 bytes). Affected
2265 file lib/silccore/silcpacket.h.
2267 * Removed all backwards support for old 0.5.x MAC thingies.
2268 The SILC packet header change makes it impossible to be
2269 backwards compatible.
2271 * Send the ENDING packet with timeout in the backup resuming
2272 protocol. This is to assure that all routers has connected
2273 to the primary router. Affected file silcd/server_backup.c.
2275 * Changed the RNG to take the first IV from random data. It
2276 used to take it from zero actually. Changed the RNG also
2277 to use /dev/urandom during session. /dev/random is used
2278 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2280 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Changed the SILC packet header to have the first two bytes
2283 (the packet length) encrypted. Affected files aroung the
2284 code tree, lib/silccore/silcpacket.[ch]. Removed the
2285 SilcPacketCheckDecrypt callback. It is not needed anymore
2286 since the silc_packet_receive_process will determine now
2287 whether the packet is normal or special.
2289 * Implemented the unidirectional MAC keys. Affected files
2290 lib/silcske/silcske.c, silcd/protocol.c and
2291 lib/silcclient/protocol.c.
2293 * Implemented the packet sequence number to the MAC computation.
2294 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2295 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2296 lib/silcclient/protocol.c.
2298 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Allow backup router to announce servers. All servers
2301 announced by backup router are added to the global list
2302 automatically. Update hte server's socket to our primary
2303 router also when backup router announces a server.
2304 Affected file silcd/packet_receive.c.
2306 * Do not update the client->router in the function
2307 silc_server_udpate_clients_by_server if the client is on
2308 global list. We might fail to find any specific server
2309 for locally connected clients and local cell clients. They
2310 should still use the `from' and not `to' as client->router.
2311 This fixes backup router resuming protocol. Affected file
2312 silcd/server_util.c.
2314 * Decrease channel statistics count only if the channel
2315 deletion worked. Affected files are silcd/server.c and
2316 silcd/server_util.c.
2318 * Added silc_server_update_servers_by_server to update origin
2319 of all server entries. Used during backup router protocol.
2320 Affected files silcd/server_util.[ch], silcd/server.c. and
2321 silcd/backup_router.c.
2323 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2324 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2325 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2326 lib/silccrypt/silchmac.c.
2328 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Assure that router cannot reroute the same channel message
2331 to the sender. Affected file silcd/packet_receive.c.
2333 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Made better checks that the channel message is not sent
2336 to the router it came from. Affected file is
2337 silcd/packet_send.c. Fixed memory leak too.
2339 * Announce informations for incoming router connection, but
2340 only after checking if it is replaced by backup router.
2341 Affected file silcd/packet_receive.c.
2343 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Fixed the backup resuming protocol to work in multiple
2346 router environment. Affected file silcd/server_backup.c.
2348 * Route packet only to one router in the function
2349 silc_server_packet_send_to_channel. Affected file is
2350 silcd/packet_send.c.
2352 * Fixed silc_server_send_notify_dest to set the broadcast
2353 flag. Fixed the silc_server_send_notify_topic to actually
2354 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2355 Affected file silcd/packet_send.c.
2357 * Changed the SFTP Filesystem interface. Changed the
2358 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2359 the filesystem operation function. The SilcSFTPFilesystem
2360 is now a context that is allocated by all filesystem allocation
2361 functions and it already includes the operations structure
2362 and filesystem specific context. It is given as argument
2363 now to the silc_sftp_server_start. This made the interface
2364 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2365 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2367 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Changed the backup router adding and getting interfaces
2370 in the server. The router that will be replaced by the
2371 specified backup router is now sent as argument. Affected
2372 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2375 * Added silc_net_addr2bin_ne to return the binary form of
2376 the IP address in network byte order. Affected files
2377 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2379 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Check for existing server ID in silc_server_new_server
2382 and in silc_server_connect_to_router_final and remove the
2383 old entry if it exists. Affected file silcd/packet_receive.c,
2386 * Send the channel message always to only one router, either
2387 in upstream or downstream. Affected file is
2388 silcd/packet_send.c.
2390 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Wrote the definition of the backup resuming protocol to the
2393 protocol specification.
2395 * Removed one redundant channel key generation from normal
2396 server during joining procedure. Removed one redundant
2397 channel key sending from server to router during joining
2398 procedure. Affected file silcd/command.c.
2400 * Made minor bugfixes to the backup router resuming protocol.
2401 Affected file silcd/server_backup.c, server.c.
2403 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Added --disable-asm configuration option. Affected files
2406 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2409 * Implemented the backup resuming protocol that is used to
2410 resume the primary router position in the cell after the
2411 primary router comes back online. Affected files
2412 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2413 and silcd/server_util.[ch].
2415 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Sleep two (2) seconds after sending QUIT command to server.
2418 Affected file lib/silcclient/command.c.
2420 * Assure that if outgoing data buffer is pending do not force
2421 send any data. Affected file silcd/packet_send.c.
2423 * Assure that if outgoing data buffer is pending do not force
2424 send any data. Affected file lib/silcclient/client.c.
2426 * Implemented the backup router support when the primary router
2427 goes down. The servers and routers can now use the backup
2428 router as new primary router without loosing connectivity.
2430 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2433 in the server to indicate disabled entry. All data read
2434 from the connection will be ignored and no data is sent
2435 for entry that is disabled. Affected files are
2436 silcd/idlist.h, silcd/server.c.
2438 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Created SFTP client and server test programs in the
2441 lib/silcsftp/tests directory.
2443 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Implemented memory filesystem (virtual filesystem) for
2446 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2449 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Implemented the SFTP (SSH File Transfer Protocol) to the
2452 lib/silcsftp. It includes SFTP client and SFTP server
2455 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Moved lib/silccore/silcprotocol.[ch] to the
2458 lib/silcutil library.
2460 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2461 take variable argument list pointer as argument. Affected
2462 file lib/silcutil/silcbuffmt.[ch].
2464 * Added silc_buffer_set function that is used to set data
2465 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2466 Affected file lib/silcutil/silcbuffer.h.
2468 * Changed various routines in the core library to use the new
2469 silc_buffer_set instead of allocating new buffer only for
2472 * Added 64-bit value formatting and unformatting support to the
2473 silc_buffer_[un]format routines. Affected file is
2474 lib/silcutil/silcbuffmt.[ch].
2476 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2477 to includes/bitmove.h.
2479 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Fixed channel user mode saving in client library. Affected
2482 file lib/silcclient/command[_reply].c.
2484 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Defined the file transfer to the SILC Protocol. Added
2487 new packet type SILC_PACKET_FTP and defined File Transfer
2488 Payload. The mandatory file transfer protocol is SFTP
2489 (SSH File Transfer Protocol). Affected file in addition
2490 of the internet draft is lib/silccore/silcpacket.h.
2492 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2493 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2494 is used as part of backup router protocol when the primary
2495 router of the cell is back online and wishes to resume
2496 the position as primary router.
2498 * Redefined the MAC generation keys in the protocol. The
2499 same key is not used anymore in both direction. Both
2500 direction will now use different keys for sending and
2501 receiving. This fixes a potential security flaw. This
2502 change causes incompatibilities in the protocol.
2504 * Redefined also the MAC computation from the packet.
2505 An packet sequence number is now added to the MAC
2506 computation. This prevents possible replay attacks against
2507 the protocol. This change too causes incompatibilities
2510 Added `sequence' field to the SilcPacketContext to hold
2511 the current sequence number for the packet.
2513 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Added `created' field to the SilcIDListData in the file
2516 silcd/idlist.h to indicate the time when the entry was
2519 * Added `created' field to the SilcChannelEntry too. Affected
2520 file silcd/idlist.h.
2522 * Added `creation_time' aguments to all the announcement functions
2523 in the server. If it is provided then only the entries that
2524 was created after the provided time frame are actually
2525 announced. Affected file silcd/server.[ch].
2527 * The protocol says that the Channel ID's IP address must be
2528 based on the router's IP address. Added check for this in
2529 the silc_server_new_channel when processing incoming New Channel
2530 Payload. Affected file silcd/packet_receive.c.
2532 * Print out the correct version with --version in SILC client.
2533 Affected file irssi/src/silc/core/silc-core.c.
2535 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Fixed WHOWAS command to check for completnes of the client
2538 entry always, not just when the command is coming from client.
2539 Affected file silcd/command.c.
2541 * Added new function silc_server_packet_queue_purge to purge the
2542 outgoing data queue to the network. After the function returns
2543 it is guaranteed that the outgoing packet queue is empty.
2544 Affected file silcd/packet_send.[ch].
2546 * Purge the outgoing packet queue in the rekey protocol's final
2547 callback to assure that all rekey packets go to the network
2548 before quitting the protocol. Affected file silcd/server.c.
2550 * Added silc_client_packet_queue_parse as similar function as
2551 in server to the client library. The affected file is
2552 lib/silcclient/client.c.
2554 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Splitted silcd/server.c and created silcd/server_util.[ch]
2557 for utility functions.
2559 * Added new socket flag SILC_SF_DISABLED to indicate that the
2560 connection is open but nothing can be sent to or received from
2561 the connection. Affected file lib/silcutil/silsockconn.[ch].
2562 The checking for disabled socket is checked in the low level
2563 silc_socket_write and silc_socket_read functions.
2565 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Allow only nicknames and channel names that fits into the
2568 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2570 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * When processing JOIN command reply in server check that if
2573 the channel exists in our global list we'll move it the local
2574 list. Affected file silcd/command_reply.c.
2576 * Fixed the check whether client is joined on the channel already
2577 in JOIN command. Affected file lib/silcclient/command.c.
2579 * Fixed the JOIN command reply to check whether the channel
2580 already exists. Affected file lib/silcclient/command_reply.c.
2582 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Added silc_ske_status_string to map the SKE error numbers
2585 to readable strings. The affected files are
2586 lib/silcske/silcske[_status].[ch].
2588 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Do not show the private channels on the WHOIS channel list
2591 as it is not allowed by the protocol. The affected file is
2594 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Assure that the packet length digged from the actual packet
2597 is something sensible in the silc_packet_decrypt_rest_special
2598 in lib/silccrypt/silcpacket.c.
2600 * Free and NULL the allocated pointer in silc_hmac_alloc if
2601 the HMAC allocation fails. The affected file is
2602 lib/silccrypt/silchmac.c.
2604 * Print the selected security properties to the log files in
2605 the server. Affected file silcd/protocol.c.
2607 * Add SKE's reference counter even if calling the completion
2608 callback manually. Otherwise it goes negative, although it
2609 does not cause any problems. The affected file is
2610 lib/silcske/silcske.c.
2612 * Remove the client entry with short timeout after giving the
2613 KILL command. Affected file lib/silcclient/command.c.
2615 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2616 case all found clients are already disconnected (WHOWAS would
2617 found them) in the server. Affected file silcd/command.c.
2619 * Update the last_receive (time of last data received) to be
2620 updated only when received private or channel message so that
2621 the idle time showed in WHOIS makes more sense.
2623 * Added boolean field `valid' in to the SilcClientEntry in the
2624 client library to indicate whether the entry is valid or not.
2625 This fixes the nickname change bug on channel when changing
2626 the nickname to be same than the old (like nick to Nick) the
2627 nickname formatter doesn't set the new nick anymore to Nick@host.
2628 Affected file lib/silcclient/idlist.[ch].
2630 * Now actually fixed the nickname changing on disconnection.
2631 Added new function silc_change_nick to the Irssi SILC Client.
2632 Affected file irssi/src/silc/core/client_ops.c,
2633 irssi/src/silc/core/silc-nicklist.[ch].
2635 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Check that the public key exists in the GETKEY command before
2638 trying to encode it. Affected file silcd/command.c.
2640 * Print some notifications on received public keys with GETKEY
2641 command in the Irssi SILC Client. Affected files are
2642 irssi/src/fe-common/silc/module-formats.[ch],
2643 irssi/src/silc/core/client_ops.c.
2645 * Use IDENTIFY command to resolve the server information in the
2646 GETKEY command instead of INFO command. Affected file
2647 lib/silcclient/command.c.
2649 * All command reply functions in the client library now calls
2650 the pending command reply callbacks even if an error has
2651 occurred. The server has done this a long time and now it was
2652 time to move the client library to this as well. Now all
2653 errors can be delivered back to the pending command reply
2654 callbacks if necessary. Affected files are
2655 lib/silcclient/command[_reply].[ch].
2657 * Change the nickname on disconnection back to the username
2658 because in reconnect the server will enforce it to it anyway.
2659 Affected file irssi/src/silc/core/silc-servers.c.
2661 * Fixed a config file parsing bug in the Irssi SILC client.
2662 Affected file irssi/src/silc/core/clientconfig.c.
2664 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * When printing the channel mode on JOIN, verify that the
2667 channel key and channel's HMAC are valid. Affected file
2668 irssi/src/silc/core/client_ops.c.
2670 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2673 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2674 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2676 * Removed channel key rekey task deleting from the function
2677 silc_server_save_channel_key. Affected file silcd/server.c.
2678 Added explicit timeout task context instead that is used to
2679 delete the task if we are registering a new task before the
2680 new task has elapsed.
2682 * When channel key rekey occurs the client library now saves
2683 the old channel key for a short period of time (10 seconds) and
2684 is able to use it in case some is still sending channel
2685 messages encrypted with the old key after the rekey. Affected
2686 file lib/silcclient/[idlist.h|client_channel.c].
2688 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Added check to the silc_server_new_id_real to not accept
2691 new ID if it is the sender's own ID. Affected file is
2692 silcd/packet_receive.c.
2694 * Assure that we do not announce ourself or the one we've
2695 sending our announcements when we're router and are announcing
2696 servers to our primary router. Affected file silcd/server.c.
2698 * Fixed silc_server_command_identify_check_client to assemble
2699 correct WHOIS packet. It send corrupted WHOIS packet and
2700 caused problem with router to router connections. Affected
2701 file silcd/command.c.
2703 Fixed also silc_server_command_whois_check the same way
2704 as for the IDENTIFY command.
2706 * Added new SilcIDListStatus to the server in the SilcIDListData
2707 structure. The status now includes the current status of
2708 the entry (like registered, resolved etc.). Affected file
2709 silcd/idlist.[ch]. Defined a bunch of different status types
2710 as well. This replaced the old boolean registered field as well.
2712 Added resolve_cmd_ident field to the SilcClientEntry structure
2713 too so that if the entry is for example being resolved so
2714 another command may attach to the same pending command reply
2715 without requiring to resolve the same entry again. This concept
2716 should optimize the WHOIS and the IDENTIFY resolving under
2717 heavy load by taking away unnecessary resolving for entries
2718 that are being resolved already.
2720 Added support for adding multiple pending commands for one
2721 command idenfier. Affected file silcd/command[_reply].[ch].
2723 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2724 before deleting the data. Otherwise the hash table will have
2725 freed data in comparison functions. Affected file is
2726 silcd/command_reply.c.
2728 * Fixed silc_idlist_replace_client_id to add the new entry to
2729 the cache with NULL nickname. Otherwise there will be invalid
2730 memory as the nickname after the nickname is freed. Affected
2731 file silcd/packet_receive.c.
2733 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2734 saved into wrong slots because the previous number of entries
2735 was not taken into account. Affected file silcd/idlist.c.
2736 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2738 * If we are router and we receive JOIN notify to a channel that
2739 does not have any users then notified client is marked as the
2740 channel founder, as it is it. The affected file is
2741 silcd/packet_receive.c
2743 * Added to the extended hash table API's table_del_*ext functions
2744 the destructor as argument too, so that the caller can decide
2745 which destructor to use or whether to use destructor at all.
2746 Affected file lib/silcutil/silchashtable.[ch].
2748 * Fixed ID Cache purging. It actually deleted the entries from
2749 the hash table after the data was freed. The hash table ended
2750 up comparing freed memory. The affected file is
2751 lib/silccore/silcidcache.c.
2753 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Fixed Irssi SILC client's KILL command's HELP syntax.
2757 * The USERS command now resolves the detailed user information
2758 if the userinfo field is missing. Affected file is
2759 lib/silcclient/command_reply.c.
2761 * Do not print error in silc_file_read if the read file does
2762 not exist. Just silently return NULL. Affected file is
2763 lib/silcutil/silcutil.c.
2765 * Fixed the silc_log_output to not wine about NULL filename
2766 and to not create some bogus " " filename. Affected file is
2767 lib/silcutil/silclog.c.
2769 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Fixed various printing bugs on the user interface in the
2772 Irssi SILC Client. Minor changes that were forgotten from
2775 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Fixed the configure.in.pre and the compilation and distribution
2778 environment to support the new autoconf 2.52. That version is
2779 now required to compile the CVS trunk.
2781 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2784 to generally parse user@fqdn format strings. Affected file
2785 lib/silcutil/silcutil.c.
2787 * Added nickname_format and nickname_force_format fields to the
2788 SilcClientParams structure. The first one defines the format
2789 for the nicknames that the library will enforce if the receives
2790 multiple same nicknames. The second one is boolean value and
2791 can be used to force the library to always enforce the format
2792 to the nicknames regardles whether there are multiple nicknames
2793 or not. This configurable formatting was employed to flexibly
2794 support accessing multiple nicknames from the user interface.
2795 The userinterface can now set the nicknames to what ever format
2796 they prefer. Affected file lib/silcclient/silcapi.h.
2798 Added function silc_client_nickname_format to the file
2799 lib/silcclient/idlist.c. It performs the nickname formatting.
2801 Added new field `hostname´ to the SilcClientEntry context.
2802 It holds the hostname of the client. Affected file is
2803 lib/silcclient/idlist.h.
2805 * Irssi SILC Client sets the nicknames in nick@hostn format.
2806 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2807 irssi/src/silc/core/silc-core.c.
2809 The WHOIS printing now also shows both the real nickname and
2810 the formatted nickname so that user knows how to access the
2811 user if there are multiple same nicknames cached. Affected
2812 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2813 printing formatting too to take the hostname now as a separate
2814 argument. The Affected file is
2815 irssi/src/fe-common/silc/modules-formats.[ch].
2817 * Changed the silc_client_get_clients_local to accept the formatted
2818 nickname as argument. It accepts the real nickname too but the
2819 formatted nickname can be used to find the true entry from
2820 multiple entries. Affected file lib/silcclient/silcapi.h and
2821 lib/silcclient/idlist.c.
2823 * Added nickname_format_parse field to the SilcClientParams.
2824 It is a callback function provided by the application to parse
2825 the nickname out of the formatted nickname string. The library
2826 calls it to get the nickname from the formatted string. Since
2827 the application generally knows better the format of the nickname
2828 string it parses it instead of the library, even though library
2829 encodes the formatted string. If the callback function is not
2830 provided then the library will use the string as is. The
2831 affected file is lib/silcclient/silcapi.h.
2833 * All the nickname strings passed to the client library in
2834 commands are now expected to be formatted nickname strings.
2835 If the command does not support the formatted nickname string
2836 it will assume that the sent string is the actual nickname.
2837 Affected file lib/silcclient/command.c.
2839 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Added public key authentication support to OPER and SILCOPER
2842 commands in the client library. Affected file is
2843 lib/silcclient/command.c.
2845 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Changed the get_auth_methdod client operation to be asynchronous.
2848 It can be async if the application resolves the authentication
2849 method from the server during the negotiation. Added new
2850 SilcGetAuthMeth completion callback that the application will
2851 call after resolving the authentication method.
2853 Added function silc_client_request_authentication_method that
2854 the application can use to resolve the authentication method
2855 from the server. Added also SilcConnectionAuthRequest callback
2856 that the library will call after the server has replied. The
2857 application can call this function if it does not know the
2858 current authentication method.
2860 Affected files are lib/silcclient/client.c and
2861 lib/silcclient/silcapi.h.
2863 * The Irssi SILC client now automatically resolves the authentication
2864 method incase any configuration information is not present (and
2865 currently there never is). The affected file is
2866 irssi/src/silc/core/client_ops.c.
2868 * Fixed public key authentication from the client library.
2869 Affected file lib/silcclient/protocol.c. Changed also the
2870 protocol specification about the public key authentication in
2871 the connection authentication protocol. The actual data to be
2872 signed is now computed with a hash function before signing.
2874 * Fixed the public key authentication from the server as well.
2875 Affected file silcd/protocol.c.
2877 * Removed the mlock()'s from the memory allocation routines.
2878 Affected file lib/silcutil/silcmemory.c. The ./configure does
2879 not check anymore for the mlock(). Affected file is
2882 * Fixed USERS command in server to allow the execution of the
2883 command for private and secret channels if the client sending
2884 the command is on the channel. Affected file silcd/command.c.
2886 * Fixed silc_client_get_clients_local to return the clients
2887 count correctly. It could return wrong value. Affected file
2888 lib/silcclient/idlist.c.
2890 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2893 types. The assembler optimizations seemed not to like 64-bit
2894 data types. The assmebler optimizations thus are now enabled
2895 also for BSD systems as opposed to only enable them for Linux.
2897 * Do not check for threads at all on BSD systems. Affected
2898 file configure.in.pre.
2900 * Removed -n and -h options from the Irssi SILC Client since
2901 they are not used in silc.
2903 * Fixed the prime generation to assure that the first digit
2904 of the generated random number is not zero since our conversion
2905 routines does not like number strings that starts with zero
2906 digit. If zero digit is seen the random number is regenerated.
2907 This caused some corrupted RSA keys when the zero first digit
2908 was met. Affected file lib/silcmath/silcprimegen.c.
2910 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2912 * Fixed WIN32 configuration in the ./configure script.
2913 Fixed to include xti.h on environments that has it.
2914 Patches by Carsten Ilchmann and andrew.
2916 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Changed the silc_id_create_client_id to be collision
2919 resistant. It is now assured that there cannot be created
2920 two same client ID's. I suspect that some weird bugs in
2921 the server were actually caused by duplicate Client IDs.
2922 Affected file silcd/serverid.[ch]. A router receiving
2923 new ID now also assures and informs the sending server
2924 if the ID caused collision.
2926 * Changed the silc_id_create_channel_id to also assure that
2927 there are no collisions.
2929 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Statement about ignoring the Mutual Authentication flag when
2932 performing rekey with PFS was a bit misleading. It is ignored
2933 if it was set in the initial negotiation, it cannot be even
2934 set in the rekey. Fixed in the ke-auth draft. Started the
2935 new versions of the protocol drafts in the doc/.
2937 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Fixed a bug in silc_client_command_identify_save when saving
2940 new channel information. The channel name was no duplicated
2941 and caused crash on exit. Affected file is
2942 lib/silcclient/command_reply.c.
2944 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Fixed the getkey command handling in the server. Send just
2947 empty OK reply to the sender if the key could not be fetched
2948 (but everything else was ok, like the key just was not available).
2949 Changed the public key parameter to optional in the protocol
2950 specs so that empty OK reply can be sent. Affected file
2953 Added a message to Irssi SILC client to tell to user if the
2954 server did not return a public key.
2956 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Fixed a channel key regeneration bug. It registered new
2959 timeout tasks exponentially until all system resources were
2960 used. Affected file silcd/server.c.
2962 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Added the SILC Document generator to the scripts/silcdoc.
2965 It can be used to generate the Toolkit Reference Manual out
2966 of the source tree. Internally it will also use the RoboDoc
2967 generator now imported in util/robodoc.
2969 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Added couple of return's in rekey protocol if error orccurred
2972 during the protocol. The execution must be terminated.
2973 Affected file silcd/protocol.c. Also, terminate the protocol
2974 always with timeout.
2976 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * The client's Client ID was created initally from the wrong
2979 nickname (it could have been in format nick@host) in the
2980 silc_server_new_client. Affected file silcd/packet_receive.c
2982 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * Added some SILC_LOG_ERROR's to various error conditions
2985 if client could not be added to ID cache. Affected files
2986 silcd/packet_receive.c and silcd/server.c.
2988 * When client's sock->user_data is freed, NULL also the
2989 client->router and client->connection pointers. Added check
2990 for these pointers being NULL to various places around the
2991 code. Affected file silcd/server.c.
2993 * Added client->data.registered == TRUE checks to various
2994 places around the code to assure that unregistered client's
2995 are not handled when it is not allowed. Affected file
2998 * Added `bool registered' fields to all
2999 silc_idlist_[server|client]_get_* routines to indicate whether
3000 the fetched client needs to be registered or not. Affected
3001 file silcd/idlist.[ch].
3003 * Add your own entry as registered to the ID cache in the
3004 server. Affected file server.c.
3006 * Fixed a bug in silc_server_new_server. The SilcServer was
3007 set as the new server's context instead of SilcServerEntry.
3008 This naturally caused some weird bugs.
3010 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Do not delete the channel rekey task when adding it
3013 for in silc_server_create_channel_key.
3015 * Changed the silc_server_create_channel_key to return
3016 TRUE or FALSE to indicate the success of the channel key
3019 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Fixed MSVC++ project files and added missing files to
3022 Makefiles under win32/.
3024 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * Do not add TCP_NODELAY flag if the operating system
3027 does not have it defined. Affected files are
3028 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3030 * Fixed buffer overflow from Irssi SILC Client. Affected
3031 file irssi/src/fe-common/core/themes.c.
3033 * Fixed double free in client library in the file
3034 lib/silcclient/client.c when disconnecting from server.
3036 * Applied double free patch from cras to Irssi SILC client.
3037 Affected files irssi/src/core/[modules/expandos].c
3039 * Fixed the disconnection handling to Irssi SILC Client.
3040 The application must call silc_client_close_connection
3041 in ops->connect client operation in case of failure of
3042 the connection. Affected file is
3043 irssi/src/silc/core/client_ops.c.
3045 * Do not set sock->protocol to NULL in the function
3046 silc_client_close_connection after executing the protocol's
3047 final callback since the sock might not be valid anymore.
3048 Affected file lib/silcclient/client.c.
3050 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Do not enable SILC_THREADS if the linking with libpthread
3053 did not happen. Affected file configure.in.pre.
3055 * Added notion to protocol specification that server must
3056 verify the sent authentication payload with CMODE when
3057 setting the channel founder key. Implemented it to the
3058 server. Affected file silcd/command.c.
3060 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * Added _EXTRA_DIST SILC distribution variable to the
3063 distributions file. It is used to conditionally add extra
3064 files or directories to the specific distribution. Affected
3065 files ./prepare, Makefile.am.pre and distributions.
3067 Removed the `_' from the start of the distribution names.
3070 * Added README.WIN32 for instructions to compile the Toolkit
3073 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Fixed a double free in disconnection in the server. Affected
3076 file is silcd/server.c.
3078 * Fixed the lib/silcske/groups.c to work now also with GMP
3079 MP library. The string conversion did not work when using
3080 specific base and the base is indicated in the string as well.
3082 * Created win32/ directory which now includes MSVC++ specific
3083 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3084 It will appear only in the toolkit distribution
3086 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Changed the key material distribution function in case when
3089 the hash output is too short. The data is now concatenated
3090 a bit differently than it used to. Made the change to the
3091 SKE protocol specification.
3093 * Added better GMP detection to configure.in.pre. A patch
3096 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Fixed a minor bug in SKE that might cause some problem on
3099 some platforms. Affected file lib/silcske/silcske.c.
3101 * Added the cookie checking for initiator in the SKE. It checks
3102 that the responder returns the sent cookie unmodified. The
3103 affected file is lib/silcske/silcske.c. Added new SKE
3104 error type INVALID_COOKIE that can be sent during the
3105 negotiation. Fixed some memory leaks as well.
3107 * Added the "invalid cookie" error message to Irssi SILC client's
3110 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Added `task_max' field to the SilcClientParams to indicate
3113 the maximum tasks the scheduler can handle. If set to zero,
3114 default values are used. Affected file lib/silcclient/silcapi.h.
3116 * Fixed memory leaks in silc_client_close_connection. Affected
3117 file lib/silcclient/client.c.
3119 * Added silc_client_del_client_entry to client library to free
3120 all memory of given client entry. Affected file is
3121 lib/silcclient/idlist.[ch].
3123 * Added new functions silc_client_del_channel and
3124 silc_client_del_server to delete channel and server entries.
3125 Affected file lib/silcclient/[silcapi.h/idlist.c].
3127 * Removed silc_client_del_client_by_id from silcapi.h.
3129 * Fixed the INFO command to return the server's own info
3130 correctly when querying by Server ID. Affected file is
3133 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3135 * Removed the non-blocking settings in WIN32 code in the
3136 silc_sock_[read/write] and added SleepEx instead. Affected
3137 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3138 of input data is now checked with FIONREAD and ioctlsocket.
3140 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * Call silc_schedule_task_del_by_context in the
3143 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3144 Affected file lib/silccore/silcprotocol.c.
3146 * Call silc_protocol_cancel for active protocols in the
3147 silc_server_close_connection if the funtion
3148 silc_server_free_sock_user_data has not been called.
3149 Affected file silcd/server.c.
3151 * Generic tasks cannot be deleted using the del_by_fd
3152 task deleting function since generic tasks does not match
3153 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3155 * Added a notion to SILCOPER help file that the SILCOPER works
3156 only on router server, not on normal server.
3158 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3160 * Added for WIN32 support for the new scheduler as well.
3161 Affected file lib/silcutil/win32/silcwin32schedule.c.
3163 * Fixed the SHA1 implementation to work on various platforms.
3165 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3168 API. It is part of the scheduler now. Everything else is
3169 as previously but some functions has changed their names.
3170 Checkout the lib/silcutil/silcschedule.h for the interface.
3171 Updated all applications to use the new interface. Affected
3172 files are lib/silcutil/silcschedule.[ch].
3174 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Found a bug in the SKE implementation. The HASH value,
3177 specified by the protocol, was not computed correctly. The
3178 public key of the responder was not added to the computation
3179 even though it is mandatory. Affected file lib/silcske/silcske.c.
3180 This unfortunately causes incompatibilities with older
3181 clients and servers.
3183 * Added WIN32 specific network init and uninit functions:
3184 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3185 the Winsock2. Affected file lib/silcutil/silcnet.h and
3186 lib/silcutil/win32/silcwin32net.c.
3188 * Set the socket always to nonblocking mode on WIN32 after
3189 reading data or writing data. Affected file is
3190 lib/silcutil/win32/silcwin32sockconn.c.
3192 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Fixed various compilation problems under WIN32. Affected
3195 files lib/silcutil/win32/silcwin32thread.c and
3196 lib/silcutil/win32/silcwin32schedule.c.
3198 * Removed all _internal.h #includes from public header
3199 files. Internal headers must never be included from
3202 Removed also the lib/silcske/payload_internal.h file.
3204 * All include files that may be needed (public and some others
3205 included by the public headers) by application developers are
3206 now copied to the ./includes directory. It does not copy any
3207 internal headers. Affected file Makefile.defines.pre and all
3208 Makefile.am's under lib/ and subdirs.
3210 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Do not change the ~/.silc directory's permissions automatically.
3213 Affected file irssi/src/silc/core/clientutil.c.
3215 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Do not cancel the protocol in silc_server_close_connection
3218 it might cause recursion. Now cancelled in the function
3219 silc_server_free_sock_user_data. Affected file silcd/server.c.
3221 * Fixed the silc_server_remove_clients_by_server to regenerate
3222 the channel keys correctly finally. Added also new function
3223 silc_server_remove_clients_channels to actually do it.
3224 Affected file silcd/server.c.
3226 * Fixed the silc_server_new_channel to not crash by giving
3227 wrong router to the new channel. Affected file is
3228 silcd/packet_receive.c.
3230 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3232 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3233 which is given as argument to the silc_client_alloc now.
3234 It can be used to configure the client and set various parameters
3235 that affect the function of the client.
3237 * The USERS command in server did not check whether the channel
3238 is private or secret. Affected file silcd/command.c.
3240 * Added new argument to the USERS command in protocol specification.
3241 The USERS command now can take the channel name as argument
3242 as well. Added support for this in client and server and
3243 updated the protocol specs.
3245 * Completed the GETKEY command in client. It can be now used
3246 to fetch also servers public key not only some clients.
3247 Affected files lib/silcclient/command[_reply].c.
3249 * Added silc_client_get_server to return server entry by the
3250 server name. Affected files lib/silcclient/silcapi.h and
3253 * Redefined the IDENTIFY command in protocol specification to be
3254 more generic. It now can be used to query information about
3255 any entity in the SILC Network, including clients, servers and
3256 channels. The query may be based either the entity's name
3257 or the ID. Added support for this in both client and server.
3259 Affected files silcd/command.c and lib/silcclient/command.c
3260 and command_reply.c.
3262 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3263 the _from_client and _from_server functions. Affected file
3266 * Added silc_client_get_channel_by_id_resolve to the file
3267 lib/silcclient/silcapi.h to resolve channel information by
3268 its ID. Added also silc_client_get_channel_by_id that
3269 does not resolve it from the server.
3271 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Added SilcServerEntry context into the client library
3274 to represent one server. The INFO command now allocates
3275 these to save the resolved server info. For now on the
3276 client library will also keep information about servers,
3277 connected and resolved with INFO.
3279 The INFO command now allocates the SilcServerEntry context
3280 and saves the server info there. The COMMAND_REPLY in
3281 the INFO now returns the parameters to application in
3282 same order as defined in the protocol specification.
3284 The entries are cached in the client->server_cache.
3286 * The INFO command is now issued after received the Client ID
3287 from the server. Affected file lib/silcclient/client.c.
3289 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3290 to the application as the mode changer might be server.
3291 It is guaranteed that NULL is not returned anymore to the
3292 application. Affected file lib/silcclient/client_notify.c.
3294 The ID Type is now also passed to the application so that
3295 it can check whether the returned entry is SilcClientEntry
3298 Added new function silc_client_get_server_by_id to return
3299 the server entry by ID. Affected files are the
3300 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3302 * Do not create the channel in the Irssi SILC Client when issuing
3303 the JOIN command but when received the sucessful JOIN command
3304 reply. Otherwise the channel might get created even though we
3305 could not join it. The Affected file is
3306 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3308 * Fixed a channel joining bug in router. The router must also
3309 check the channel modes, invite and ban lists etc. when serving
3310 the JOIN command sent by normal server. Affected file is
3311 silcd/command.c. The router now resolves the client's
3312 information from the server who sent the JOIN command if it
3313 does not know it, and processes the JOIN command only after
3316 * Changed the SilcCommandCb to take new argument; void *context2.
3317 Affected file lib/silccore/silccommand.h
3319 The second argument in the command callbacks in the server now
3320 includes the SilcServerCommandReplyContext if the command was
3321 called as pending command callback from the command reply.
3322 Otherwise it is NULL. When called as pending the status of the
3323 command reply will be checked and if it was erronous the
3324 error will be sent to the original sender of the command.
3325 This way the client always receives the error messages even
3326 though the server was actually the one who received the error
3327 when it resent the command to router, for example. Affected
3328 files silcd/command[_reply].[ch].
3330 * Fixed sending WHOWAS command's error message to client if
3331 the requested client could not be found. It was missing.
3334 * Changed the CMODE and CUMODE commands reply arguments in the
3335 protocol specification. The Channel ID is now sent in both
3336 of the commands to identify the channel. Implemented this
3337 new feature to the client and server. Affected files
3338 lib/silcclient/command_reply.c and silcd/command.c.
3340 * Made better checks for invite and ban lists in the JOIN
3341 command in server. Affected file silcd/command.c.
3343 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * The server now performs the incoming host IP/DNS lookup
3346 using the silc_socket_host_lookup and thus does not block
3347 the server anymore. Affected file silcd/server.c.
3349 * Completed the multi-thread support for SILC Scheduler in
3350 the lib/silcutil/silcschedule.c.
3352 * Fixed the configure.in.pre to detect the pthread correctly
3355 * Fixed a deadlock in silc_task_queue_wakeup in the file
3356 lib/silcutil/silctask.c.
3358 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Added new function silc_schedule_wakeup that is used in
3361 multi-threaded environment to wakeup the main thread's
3362 schduler. It needs to be used when a thread adds a new task
3363 or removes a task from task queues. After waking up, the
3364 scheduler will detect the task queue changes. If threads
3365 support is not compiled in this function has no effect.
3366 Implemented the wakeup mechanism to both Unix and WIN32
3367 systems. Affected files are lib/silcutil/silcschedule.[ch],
3368 lib/silcutil/unix/silcunixschedule.c and the
3369 lib/silcutil/win32/silcwin32schedule.c.
3371 * Added new function silc_task_queue_wakeup to wakeup the
3372 scheduler by the specified task queue. Affected file
3373 lib/silcutil/silctask.[ch].
3375 * The silc_socket_host_lookup_start now wakes up the scheduler
3376 after adding the timeout task. Affected file is
3377 lib/silcutil/silcsockconn.c.
3379 * The silc_socket_host_lookup is synchronous now if the threads
3380 support is not compiled in. However, the callback is still
3381 called asyncronously through the scheduler, anyway. Affected
3382 file lib/silcutil/silcsockconn.c.
3384 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Added new function silc_socket_host_lookup to perform
3387 asynchronous IP and FQDN lookups for the socket connection.
3388 Affected files lib/silcutil/silcsockconn.[ch].
3390 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3392 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3393 that may or may not compile the mutex support in.
3395 Changed the silc_mutex_alloc interface. It allocates the
3396 mutex now to the sent pointer and returns TRUE or FALSE.
3398 Affected file lib/silcutil/silcmutex.h.
3400 * Wrote the SILC Task Queue interface to support multi-threads.
3401 Affected file lib/silcutil/silctask.[ch].
3403 * Wrote the SILC Scheduler to support multi-threads. Affected
3404 file lib/silcutil/silcschedule.c.
3406 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3409 in lib/silcutil/win32/.
3411 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3413 * Defined SILC Mutex API and SILC Thread API and implemented
3414 them for Unix. Affected files are
3415 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3416 lib/silcutil/unix/silcunixmutex.c and
3417 lib/silcutil/unix/silcunixthread.c.
3419 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Fixed the silc_server_remove_clients_by_server's channel
3422 key re-generation. The hash table handling was incorrect
3423 and would not work with many channels. Affected file is
3426 * Fixed some memory leaks around the server code.
3428 * Rewrote the silc_server_get_users_on_channel to support IPv6
3429 based Client ID's. Affected file silcd/server.c.
3431 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3432 specification. However, a separate document must be written
3433 to define the detailed signing procedure and the payload
3434 associated with the flag. Defined the flag to the
3435 lib/silccore/silcchannel.h as well.
3437 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3439 * Changed the dynamic tables to static size tables in the
3440 lib/silccrypt/silchmac.c.
3442 * Removed GCC dependencies from the code. A patch by cras.
3444 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3446 * Do not show the error "Error receiving packet bla bla"
3447 in server if it really was not an error (-2 means that reading
3448 is pending). Affected file silcd/server.c.
3450 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3452 * Fixed a possible crash in silc_server_remove_clients_by_server
3453 in silcd/server.c. Fixed there also some memory leaks.
3455 * Fixed the silc_idlist_replace_client_id. It could replace
3456 wrong key in the hash table. Affected file silcd/idlist.c.
3458 * Do not check whether there are global users on the channel
3459 if the channel->global_users is FALSE. Affected functions
3460 silc_server_remove_from_one_channel and
3461 silc_server_remove_from_channels in silcd/server.c. Also,
3462 do not check if the removed client is local as we can be
3463 sure that global client was not removed from the channel
3464 and checking for global users is not needed.
3466 * The silc_server_remove_clients_by_server now re-generates
3467 the channel keys correctly for those channels that had
3468 clients removed from them. Affected file silcd/server.c.
3470 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Found the reason of random crashes in the server. We weren't
3473 ignoring the SIGPIPE signal (which can be sent in write())
3474 and it crashed the server. Affected file silcd/silcd.c.
3476 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Assure that sock->user_data is not NULL in the function
3479 silc_server_packet_send in silcd/packet_send.c.
3481 * Disconnect the remote connection if it could not be added
3482 to any ID lists in the server. The affected file is
3485 * Check in silc_server_packet_send[_real/dest] that the
3486 socket is not disconnecting and ignore the data if it is.
3487 Affected file silcd/packet_send.c.
3489 * Define inline to __inline on native WIN32 compilation.
3490 Affected file includes/silcwin32.h.
3492 * Added some explicit type casts for inline code since MSVC
3493 require them. Affected files lib/silcutil/silcbuffer.h,
3494 lib/trq/silcdlist.h and lib/trq/silclist.h.
3496 * Print warning in log files from now on if the packet
3497 decryption fails. Affected file silcd/server.c.
3499 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Changed the `say' client operation's interface to accept
3502 new `type' argument to indicate the type of the message sent
3503 by the library. The application may filter the library's
3504 messages according the type. The affected file is the
3505 lib/silcclient/silcapi.h.
3507 * Added two new functions to lib/silcclient/silcapi.h:
3508 silc_client_del_client and silc_client_del_client_by_id.
3509 Affected file lib/silcclient/idlist.c.
3511 * Moved the clientincludes.h from includes/ to silc/ and
3512 serverincludes.h from includes/ to silcd/.
3514 * The modes for the CMODE and CUMODE are now passed as
3515 uint32 for application with COMMAND_REPLY. The affected
3516 file is lib/silcclient/command_reply.c.
3518 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * /WHOIS without arguments shows client's own information.
3521 Affected file lib/silcclient/command.c.
3523 * Changed PING to not accept any arguments. The specs
3524 says that client can ping only the connected server so
3525 requiring an argument is not needed. Affected file is
3526 lib/silcclient/command.c.
3528 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3530 * Fixed a fatal bug in private message sending and reception
3531 encryption and decryption when using private message keys.
3532 The implementation was incorrect and did not follow the
3533 specification. It causd that some of the message were
3534 lost since it did not use the sending and receiving keys
3535 as the protocol suggests. This has been fixed and will cause
3536 incompatibilities with older clients when sending private
3537 message encrypted with private message keys. Affected files
3538 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3539 and various other in Irssi SILC Client.
3541 Added `responder' boolean argument to the functions
3542 silc_client_add_private_message_key[_ske] to indicate when
3543 the key is added as responder or initiator of the key
3546 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Removed the silc_ske_check_version function and created
3549 a SilcSKECheckVersion callback. Added also a function
3550 silc_ske_set_callbacks that is now used to set all SKE
3551 callbacks. The callback functions are not given to
3552 the SKE functions anymore, but this function is used to
3555 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3557 * Added `silc_version' argument to the silc_client_alloc
3558 to define the version of the application for the library.
3559 The library will use the version string to compare it
3560 against the remote host's (usually a server) version
3561 string. Affected file lib/silcclient/silcapi.h
3563 * Added the KE protocol context to Key Agreement context
3564 in client library so that we can abort the SKE if it
3565 is in process when we get timeout. Affected file is
3566 lib/silcclient/client_keyagr.c.
3568 * Do not resolve the client ID forever if it returns in the
3569 first time that such client does not exist. This was done
3570 for example with private message. Affected file is
3571 lib/silcclient/client_prvmsg.c.
3573 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3575 * Do not add regex.h for WIN32. The affected file
3576 includes/silcincludes.h.
3578 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3579 not work yet 100%. It generates the DLL's automatically
3580 when compiling with --with-win32 under cygwin.
3582 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3584 * lib/contrib/regex.c is not compiled on WIN32.
3586 * Added silc_net_get_socket_opt function to the
3587 lib/silcutil/silcnet.h.
3589 * Added includes/silcwin32.h for WIN32 specific includes
3592 * Do not use ptime structure or any of the posix process
3593 functions on WIN32 in lib/silccrypt/silrng.c.
3595 * Added silc_gettimeofday to provide generic function
3596 for struct timeval on all platforms. Added the function
3597 to lib/silcutil/silcutil.h.
3599 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3602 library as they clearly belong there. As a plus side we
3603 can make the actual socket connection routines platform
3606 Added also new generic function silc_socket_read and
3607 silc_socket_write (that used to be silc_packet_[read/write].
3608 The implementation of these are platform specific.
3610 * Added WIN32 specific routines of silc_socket_[read/write]
3611 to lib/silcutil/win32/silcwin32sockconn.c.
3613 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Added preliminary support for native WIN32 compilation under
3616 cygwin (using the -mno-cygwin option for GCC) to the
3617 ./configure.in.pre. The --with-win32 now prepares the
3618 compilation for native WIN32.
3620 * Rewrote the SILC Scheduler interface in the file
3621 lib/silcutil/silcschedule.h. The scheduler is now context
3622 based and does not have anymore any global static scheduler.
3623 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3624 and created lib/silcutil/win32 directory for WIN32 based
3627 * Added Unix specific network routines to the
3628 lib/silcutil/unix/silcunixnet.c and the old
3629 lib/silcutil/silcnet.c includes now only generic routines.
3631 Added WIN32 specific network routines to the
3632 lib/silcutil/win32/silcwin32net.c.
3634 * Added Unix specific utility functions from the
3635 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3637 * Added WIN32 SILC Scheduler to the file
3638 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3641 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3643 * Do not handle JOIN notify in the server if the target client
3644 is not registered (idata->registered == FALSE). The affected
3645 file is silcd/packet_receive.c.
3647 * Update the nickrec->founder in event_cumode in the Irssi SILC
3648 client. Affected file irssi/src/silc/core/silc-channels.c.
3650 * Fixed the CUMODE_CHANGE notify handling in the server when
3651 server and router are announcing their clients on channels.
3652 Now the mode changes are saved and notified correctly. The
3653 affected file is /silcd/packet_receive.c.
3655 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3656 They really did not replace the cache entry in the ID Cache.
3657 Now they do that. Affected file silcd/idlist.c.
3659 * Fixed the KICK notify handling in the Irssi SILC client to
3660 update the channel records so that the kicked client does not
3661 appear to be on the channel. The affected file is
3662 irssi/src/silc/core/silc-channels.c.
3664 * Always update the conn->current_channel when executing command
3665 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3667 * Fixed the KILL notify handling in Irssi SILC client to remove
3668 the killed client on all channels.
3670 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Fixed the silc_parse_command_line to remove extra spaces
3673 from the start and end of the arguments. Affected file is
3674 lib/silcutil/silcutil.c.
3676 * Cancel and free any active protocol in the function
3677 silc_server_close_connection. Affected file silcd/server.c.
3679 * Cancel and free any active protocol in the function
3680 silc_client_close_connction. Affected file is
3681 lib/silcclient/client.c.
3683 * Do not execute the KILL command for clients that are in
3684 history (ie. they are not in the network). Affected file is
3687 * Fixed KILL notify handling, client does not crash anymore.
3688 Affected file irssi/src/silc/core/silc-channels.c.
3690 * Reduced the default packet buffer size from 2048 to 1024 in
3691 lib/silccore/silcpacket.c.
3693 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3694 counter to the SKE context that is incresed when the SKE library
3695 performs async operation outside the library. If the outside
3696 process frees the SKE context and FREED status will be set
3697 and the library will detect after the sync operation that the
3698 libary is freed. The affected files are
3699 lib/silcske/silcske[_status].[ch].
3701 * Resolve the client entry information in the function
3702 silc_client_channel_message to assure that NULL pointer is not
3703 passed as client entry to the application. */
3705 * Fixed the task timeout calculation to assure that there is
3706 never negative timeouts. The affected file is
3707 lib/silcutil/silcschedule.c.
3709 * Fixed the channel user mode notification sending in server.
3710 It was sent point-to-point to the router (or to server by router)
3711 but it needs to be destined to a channel. The routines now
3712 supports sending the channel user mode notifys to the channels
3713 when announcing clients and channels. Affected files are
3714 silcd/server.c and silcd/packet_receive.c.
3716 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3717 It did not actually replace the old channel entry in the cache.
3718 Affected file lib/silcclient/client_notify.c.
3720 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Fixed a possible crash in silc_packet_send_prepare. It now
3723 assures always that there is enough space in the buffer and
3724 at the tail area of the buffer (for MAC).
3726 Fixed the inbound buffer reallocation in silc_packet_read.
3727 It was old code and did not handle the reallocation correctly.
3730 The affected file is lib/silccore/silcpacket.c.
3732 * Fixed buffer overflow in silc_parse_nickname in the file
3733 lib/silcutil/silcutil.c.
3735 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * make install generates new server keys only if there is not
3740 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3743 Added check that if the NOREPLY is set then we will not send
3744 the away message. This avoids infinite loop of away messages
3745 if both clients are away. The affected file is
3746 lib/silcclient/client_prvmsg.c.
3748 * Fixed client crash if /NICK was given without arguments.
3749 Affected file lib/silcclient/command.c.
3751 * Server does not send the invite list in INVITE command back
3752 to the client if the list was not altered. Added this notion
3753 to the protocol spec as well. Affected file silcd/command.c.
3755 Fixed possible crash in INVITE command by checking the
3756 value of silc_server_get_client_route command.
3758 * Fixed the INVITE notify type handling. The arguments are now
3759 taken in correct order and client does not crash. The affected
3760 file is irssi/src/silc/core/silc-channels.c.
3762 Removed the "Inviting xxx to channel" message from the
3763 client library away and let the application handle it.
3764 Affected file lib/silcclient/command.c. Added that message
3765 to Irssi SILC client's message formats.
3767 * Fixed CMODE command crash in client. It now checks the
3768 amount of arguments correctly and does not crash. The affected
3769 file is lib/silcclient/command.c.
3771 * Do not create new channel automatically in silc_channels_join
3772 but check whether the channel by that name already exists.
3773 Affected file irssi/silc/core/silc-channels.c.
3775 * Do not send the SERVER_SIGNOFF to router if the disconnected
3776 entity was the router. Affected file silcd/server.c.
3778 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3779 SILC client as it was missing from there.
3781 Added the handling of the KICK notify to the Irssi SILC client
3782 as it was missing. Added "you have been kicked" message to
3783 Irssi SILC client's message modules formats.
3785 Added the handing of the KILL notify to the Irssi SILC client
3786 as it was missing. Added the kill message module formats
3789 The affected file is irssi/src/silc/core/silc-channels.c.
3791 * The router did not save the channel mode the server announced.
3792 Affected file silcd/packet_receive.c.
3794 * Fixed a possible crash in INFO command in server. If the
3795 server did not provide the server info it crashed. Affected
3796 file silcd/command.c.
3798 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Fixed the GETKEY command in the server to check also the
3801 global list. Otherwise the GETKEY would not work correctly
3802 in normal SILC server. Affected file silcd/command.c.
3804 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Fixed GETKEY crash, it crashed if the command did not succseed.
3808 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3811 is now real and not just an macro interface to GMP.
3813 Removed the entire GMP from the source tree and imported new
3814 NSS MPI library instead. Reason for removing GMP is that it is
3815 extremely large and compiles extremely slow. The NSS MPI
3816 is only a few files and compiles in less than 10 seconds.
3817 The speed is also about the same as GMP. The MPI is imported
3818 to lib/silcmath/mpi.
3820 If the system has GMP installed we will still use the GMP.
3821 If it is not then the NSS MPI will be compiled.
3823 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Merged a long nickname (127 characters long) crash bugfix from
3826 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3828 * Merged a freed memory reference bugfix from Irssi CVS tree.
3829 Affected file irssi/src/core/commands.c.
3831 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Added the server's public key sving and verification to the
3834 server when performing the SKE. This was missing and the
3835 remote server's (or router's) public key was accepted without
3836 checking whether we have it previously or trust it at all.
3837 Affected file silcd/protocol.c.
3839 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Check in the silc_server_timeout_remote if protocol is active
3842 and make sure that the protocol's final callback is called so
3843 that all memory if freed. Affected file silcd/server.c.
3845 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * silc_server_whois_send_reply crashed the server if the nickname
3848 was 127 characters long. Affected file silcd/command.c.
3850 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Added sanity check to the silc_server_new_client. If the hostname
3853 is provided inside username then check that the provided hostname
3854 really is the same as the resolved one. If the hostname was not
3855 resolved then check it from the public key. Affected file is
3856 silcd/packet_receive.c.
3858 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3859 if the server disconnected us and the connection is not valid
3860 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3862 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3863 the library to the lib/silcutil/silcutil.[ch].
3865 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Close log file after open. Affected file
3868 lib/silcutil/silclog.c.
3870 * Check whether sock == NULL in silc_client_send_packet and return
3871 if it is. Affected file lib/silcclient/silcclient.c.
3873 * Check rec->entry == NULL in the Irssi SILC Client before
3874 sending the channel message. Affecte file is
3875 irssi/src/silc/core/silc-servers.c.
3877 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Merged a splitted window bugfix from Irssi CVS tree. The
3880 affected file is irssi/src/fe-text/textbuffer-view.c.
3882 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3883 It did not print nickname.
3885 * Improved the distributions system a bit.
3887 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3890 irssi/src/fe-text/gui-window.c.
3892 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3893 to in-active server. The affected file is
3894 irssi/src/silc/core/client_ops.c.
3896 * Resolve the client in USERS command reply if the entry does
3897 not have username resolved. The affected file is
3898 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3899 command to WHOIS command to really resolve stuff. The USERS
3900 is not used any more in any critical section so WHOIS can
3901 be used even though it might be slower than IDENTIFY.
3903 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3906 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Changed the protocol API a bit more consistent in the
3909 lib/silccore/silcprotocol.[ch].
3911 * Changed the following headers to ROBODoc format:
3913 lib/silccore/silcpayload.h
3914 lib/silccore/silcprotocol.h
3915 lib/silccore/silcsockconn.h
3917 All core library headers are now formatted.
3919 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Fixed a bug in Irssi SILC client; do not show that you are
3922 server/router operator if you really are not. Affected file is
3923 irssi/src/silc/core/client_ops.c.
3925 * Renamed silc_command_free_payload to silc_command_payload_free.
3926 Affected file lib/silccore/silccommand.h
3928 * Added silcmath.h to include the prototoypes of various routines
3929 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3932 * Changed the following headers to ROBODoc format:
3934 lib/silccore/silcchannel.h
3935 lib/silccore/silccommand.h
3936 lib/silccore/silcid.h
3937 lib/silccore/silcidcache.h
3938 lib/silccore/silcmode.h
3939 lib/silccore/silcnotify.h
3940 lib/silccore/silcpacket.h
3941 lib/silcmath/silcmath.h
3943 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Added checking to the server code not to start the server if
3946 ciphers and stuff are not configured properly. Affected files
3947 silcd/serverconfig.[h] and silcd/server.c.
3949 * Changed the layout of the header files of the public interfaces
3950 in the SILC libraries. The new layout supports ROBODoc
3951 documentation tool (and some others) so that it is easy to create
3952 a library reference manual. All the other headers and source
3953 code must still follow the CodingStyle document. Also source
3954 code must not include these ROBODoc stuffs, only the headers.
3955 Furthermore, all public interface headers must now be named
3956 by using `silc' prefix, example: silcapi.h, silccipher.h.
3957 Some files were renamed due to this. All the other headers
3958 must not be used as public interfaces. I will update the
3959 CodingStyle document later. Changed following headers, so far:
3961 lib/silcclient/silcapi.h
3962 lib/silccore/silcauth.h
3963 lib/silccore/silcprivate.h
3964 lib/silccrypt/silcdh.h
3966 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Removed silc_client_packet_send_flush from the client library
3971 as it is not needed. Affected file lib/silcclient/client.[ch].
3973 * Added printing of message of unresolved authentication method
3974 to the Irssi SILC client. Added it to the module formats.
3975 Removed the same message from the client library.
3977 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Added new distribution feature, DISTLABEL. Every distribution
3980 can define own preprocessor label that can be used in the
3981 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3982 file distributions, acconfig.h.pre and prepare.
3984 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Added Makefile.defines_int to include the actual definitions
3987 for Makefile.defines.in. Tested the new distribution system,
3988 created distributions and tested installation.
3990 * Added AWAY message printing to the Irssi SILC client. Added
3991 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3993 * Added SCONNECT command to call the SILC's CONNECT command.
3994 Cannot use CONNECT directly since Irssi uses that internally.
3995 Affected file irssi/src/silc/core/silc-servers.c.
3997 Added ACTION local command. It is same as ME command but takes
3998 the channel as mandatory argument.
4000 Rewrote some of the Irssi's help files to suite for SILC
4003 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added Makefile.defines[.in] that should for now on be included
4006 in all Makefile.am file in the source tree. That file includes
4007 all common compilation definitions for SILC source tree.
4009 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Minor changes to the ./prepare script to change the package
4012 name according the distribution name to the configure.in.
4014 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Created new distribution system. Added file `distributions'
4017 that defines all the distributions that can be created out of
4018 the SILC source tree. The ./prepare script now reads that
4019 file to determine how to prepare the distributions. The
4020 first argument to the ./prepare is the name of the distribution
4021 and second is the version of the distribution. If given
4022 without arguments it creates the default (toolkit) distribution
4023 with the default version (defined in ./prepare).
4025 All Makefile.am files that are subject to the distributions
4026 are now named as Makefile.am.pre. These are ./Makefile.am
4027 and lib/Makefile.am. Others may be changed later.
4029 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Added invite list, ban list, some key management and connection
4032 error message printing to module formats in the Irssi SILC client.
4034 * Added new silc_client_set_away_message to set the away message
4035 that is back to the person who sent private message. The
4036 affected file lib/silcclient/silcapi.h and the
4037 lib/silcclient/client_prvmsg.c.
4039 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Fixed the private message sending in the Irssi SILC client,
4042 added local command KEY to the Irssi SILC client.
4044 Added key management and key agreement message formats to the
4045 irssi/src/fe-common/silc/module-formats.[ch].
4047 Added USERS (alias WHO) printing, server/router operator
4048 indication and LIST command printing to the module formats.
4050 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Fixed channel joining notify handling, cumode notify handling
4053 from Irssi SILC client.
4055 * Added SILC specific module-formats to the Irssi SILC client so
4056 that SILC specific message hilighting, colors etc is possible.
4057 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4059 Added channel mode, channel user mode, actions, notices,
4060 whois and whowas printing to the the module-formats.c.
4062 * Fixed a bug in channel deletion in the server. The channel
4063 is not left to the cache even if the channel founder auth mode
4064 is set when there are no users anymore on the channel. Affected
4065 file silcd/server.c.
4067 * The silc_net_localhost now resolves the entire hostname including
4068 the domain name. Affected file lib/silcutil/silcnet.c.
4070 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Changed the ask_passphrase client operation to be ascynchronous.
4073 It has now a completion callback and a context that the
4074 application must call after it has got the passphrase from
4075 the user. Affected files lib/silcclient/silcapi.h,
4076 lib/silcclient/protocol.c, lib/silcclient/command.c and
4079 Added SilcAskPassphrase callback that the application calls
4080 to deliver the passphrase to the library.
4082 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4083 The public key verification and especially a certificate
4084 verification is asynchronous procedure.
4086 Added new SILC_SKE_STATUS_PENDING status to indicate the
4087 request is pending and a callback will be called to finalize
4090 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4091 indicate that remote end did not send its public key (or
4092 certificate), even though we require it. Added check for this
4093 condition in the SKE. This was a security bug, now fixed.
4095 Defined new SilcSKEVerifyCbCompletion callback that is called
4096 when the verification process is completed.
4098 The affected files lib/silcske/silcske_status.h and
4099 lib/silcske/silcske.[ch].
4101 * Changed the verify_public_key client operation to be async
4102 as well. Defined SilcVerifyPublicKey callback that is used to
4103 indicate the success of the public key verification process.
4105 Changed the server and client to use the new async client
4108 * Changed the Irssi SILC client's internal scheduler to be called
4109 twice as many times as it used to be. As a result the client
4110 should be a bit faster now. Affected file is
4111 irssi/src/silc/core/silc-core.c.
4113 * Added support to Irssi SILC client of asynchronous public key
4114 verification and passphrase inquiry. Affected file is
4115 irssi/src/silc/core/silc-core.c.
4117 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Do not say "You have left channel %s" in client library.
4120 Moved it to the application. Affected files are
4121 lib/silcclient/command.c and silc/client_ops.c.
4123 * Fixed silc_client_get_clients. Command context was not
4124 duplicated and was freed memory in the callback. Affected
4125 file lib/silcclient/idlist.c.
4127 * Do not say "you are now talking..." on JOIN command in the
4128 client library. The appliation must handle it.
4130 * Do not say ".. changed topic to" in command reply in the
4131 client libary. The application must handle it.
4133 * Fixed TOPIC command sending in the client library.
4135 * Fixed a memory leak in silc_client_command_free in the file
4136 lib/silcclient/command.c.
4138 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Imported a modified version of Irssi client to the source tree.
4141 The Irssi will be used to create a new client called
4142 Irssi SILC. Imported to irssi/.
4144 Added silc_core_init_finish function to the Irssi. Affected
4145 file irssi/configure.in.
4147 A lot changes in the Makefile.ams around the irssi tree.
4149 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Do not rehash if the new size is same as the old size of the
4152 hash table, in the silc_hash_table_rehash*. The affected file
4153 lib/silcutil/silchashtable.c.
4155 * Replaced hash_table_del_by_context calls from the server
4156 (when channel->user_list and client->channels) to the
4157 hash_table_del as it is sufficient and faster.
4159 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Added silc_hash_table_list, silc_hash_table_get and the
4162 SilcHashTableList structure to provide an alternative way to
4163 traverse the hash table. The affected files are
4164 lib/silcutil/silchashtable.[ch].
4166 * Changed the server's idlist routines to use the hash table
4167 routines to optimize the code.
4169 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Replaced the client entry's `channel' list and channel entry's
4172 `user_list' list to hash tables for optimized lookup. Changed
4173 the code to use the hash table interface around the code.
4174 Affected file lib/silcd/idlist.[ch].
4176 * Added `auto_rehash' boolean argument to the function
4177 silc_hash_table_alloc to indicate whether the hash table should
4178 auto-rehash when it thinks is appropriate time. It will
4179 increase the hash table size if the there is twice as much
4180 entries in the table than the size of the table, and will
4181 decrease the size if there are twice as less entries than
4182 the size of the table.
4184 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4188 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * silc_idcache_purge_by_context deletes the entry now by context
4191 as it is supposed to do. Affected file lib/silccore/idcache.c.
4193 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4194 client is not anymore valid (WHOWAS givens the info) and not
4195 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4197 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Removed the `data' and `data_len' arguments from the ID Cache
4200 interfaces and added `name' argument. ID Cache does not handle
4201 anymore the binary data only a names associated with given ID.
4203 * When hashing a Client ID with silc_hash_id the entire ID is
4204 not hashed anymore, instead only the hash of the Client ID is
4205 hashed. This way we can access the Client ID from the cache
4206 with Client ID but with the hash of the ID (which is a hash of
4207 the nickname) as well without any difference in performance.
4209 Added also silc_idcache_find_by_id_one_ext to do one on one
4210 searching when we have the actual ID. Added also function
4211 silc_hash_client_id_compare. The affected files are
4212 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4214 * When hashing the name associated with a ID it is always done
4215 in lowercase. This way we can access the cache without worrying
4216 about case-sensitivity, even though, for example nicknames are
4219 * Fixed a bug in server with channel message sending. It put
4220 wrong ID type as destination ID. The affected file
4221 silcd/packet_send.c.
4223 * silc_idcache_del_by_context now deletes from all hash tables
4224 by context. Affected file lib/silccore/idcache.c.
4226 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Changed the client library to use the new ID Cache interface.
4229 Changes around the source tree.
4231 * Added silc_hash_table_rehash_ext to rehash with specific
4232 hash function. Affected file lib/silcutil/silchashtable.[ch].
4234 * Added silc_hash_string_compare to compare two strings in the
4235 hash table. Affected file lib/silcutil/silcutil.[ch].
4237 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Added new function silc_idcache_del_by_context into the
4240 lib/silccore/idcache.[ch].
4242 * Changed the server's ID list routines to use the new ID Cache
4243 interface. Changes around the source tree.
4245 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added silc_hash_table_del[_by_context]_ext functions in to the
4248 lib/silcutil/silchashtable.[ch].
4250 Removed silc_hash_table_find_all* routines and added new
4251 silc_hash_table_find_foreach to replace them.
4253 Added silc_hash_table_replace_ext function as extended
4254 replacing function. Separated the simple hash table interface
4255 from the extended hash table interface in the file
4256 lib/silcutil/silchashtable.h.
4258 * Fixed minor bugs and changed it to use some of the new
4259 hash table functions in lib/silccore/idcache.c
4261 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added new function silc_hash_table_find_all to return all keys
4264 in the hash table by the specified key. As the hash table is
4265 collision resistant it also makes it possible to have several
4266 duplicate keys in the hash table. This function may be used to
4267 find all of the keys from the hash.
4269 Added user_context arguments to the SilcHashFunction,
4270 SilcHashCompare and SilcHashDestructor to deliver user specified
4273 Added new fuctions silc_hash_table_find[_all]_ext to do
4274 extended lookup with specified hash and compare functions and
4275 specified user contexts.
4277 Added new function silc_hash_table_add_ext to add the key
4278 with specified hash function and user context.
4280 Added new function silc_hash_table_foreach to traverse all
4281 entrys in the hash table. Added SilcHashForeach callback
4284 Added new function silc_hash_table_del_by_context to delete
4285 the entry only if the context associated with the key matches.
4287 Affected files are lib/silcutil/silchashtable.[ch].
4289 * Removed silc_hash_[server/client/channel]_id and added just
4290 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4291 silc_hash_id_compare to compare two ID's using as the hash table
4292 comparison function. Added also silc_hash_data to hash
4293 binary data and silc_hash_data_compare to compare it.
4295 * Removed silc_idlist_find_client_by_hash as it is not needed
4296 anymore. Affected file silcd/idlist.[ch].
4298 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4299 to use internally the SilcHashTable. The new ID Cache is a lot
4300 faster than the old one. Some of the ID Cache interface was also
4301 rewritten and obsolete and stupid functions were removed.
4303 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Added entry_count field to the SilcHashTable to keep the number
4306 of the entries in the table. Implemented the function
4307 silc_hash_table_rehash. Added new function
4308 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4310 Fixed a minor bug in silc_hash_table_free.
4312 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4313 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4314 into the lib/silcutil/silcutil.[ch].
4316 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Implemented a collision resistant hash table into the
4319 lib/silcutil/silchashtable[ch]. See the header and the source
4320 for the SilcHashTable API.
4322 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Merged dotconf version 1.0.2 into lib/dotconf.
4326 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Do not compile anything in lib/silcsim/* if the SIM support
4329 is not enabled. The tree should now compile without problems
4332 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Compiled the SILC under cygwin. Compiled and tested briefly
4335 without problems. More tests needed. The SIMs didn't compile
4338 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4340 * Fixed possible crash in silc_get_username in the
4341 lib/silcutil/silcutil.c.
4343 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Fixed a va_arg in silc/client_ops.c.
4347 * Oops, RC5 routines were named AES and caused some problems
4348 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4350 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4352 * Added new SilcIDIP structure into the lib/silccore/id.h and
4353 replaced the old `ip' fields from all SILC ID's to that type.
4354 This is a step towards IPv6 support.
4356 The silc_id_get_len takes now the ID as an extra argument.
4357 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4358 both IPv4 and IPv6 based ID's.
4360 The affected files are lib/silccore/id.[ch] and other files
4361 around the tree using these routines.
4363 * Removed the ID length arguments in server from various
4364 silc_server_send_notify_* routines -> they are not needed
4367 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Fixed memory leak in silc_encode_pem_file in the file
4370 lib/silcutil/silcutil.c.
4372 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Check minor version as well in the SKE. Affected files are
4375 silcd/protocol.c and lib/silcclient/protocol.c.
4377 * Added --identifier option to the server so that an identifier
4378 can be when creating the public key for the server. Affected
4379 file is silcd/silcd.c.
4381 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4382 lib/silccrypt/silcpkcs.c.
4384 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Register default ciphers and stuff when using -C option with
4387 the server. Affected file sildc/silcd.c.
4389 * Put back the servers public key filename format, it is better
4390 than the new one. For now, the client keys are saved with the
4391 new filename format. The affected file silc/client_ops.c.
4393 * Implemented the Cipher API for the rest of the ciphers that
4394 did not implement it or implemented it the wrong way.
4396 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Register default ciphers and stuff when using the -S option
4399 in the client. Affected file silc/silc.c. Same also when
4400 creating new key pair with -C option.
4402 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Fixed the silc_verify_public_key client operation function to
4405 save the public keys differently. The fingerprint is now
4406 used as filename and not the hostname. This way also the
4407 client keys are saved uniquely and not with hostnames. The
4408 affected file is silc/client_ops.c.
4410 * Trimmed the silc_hash_fingerprint function to remove extra
4411 whitespaces from the end of the fingerprint. The affected
4412 file is lib/silccrypt/silchash.c.
4416 * Added silc_cipher_register_default function to register all
4417 default ciphers. It can be used when configuration files
4418 does not exist and the application does not want any specific
4419 ciphers in any specific order.
4421 The SilcDList is now used as silc_cipher_list dynamically
4422 allocated cipher list. Removed the static list all together
4423 and now all ciphers must be allocated to the dynamic list.
4424 The silc_cipher_alloc routine was changed to check only the
4427 All silc_cipher_* routines that used to return int returns
4430 The affected files lib/silccrypt/silccrypt.[ch].
4432 * The same thing was done to silc_hash_* as for silc_cipher_*
4433 routines. Affected files lib/silccrypt/silchash.[ch].
4435 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4436 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4437 Added also silc_pkcs_[un]register[_default] functions.
4438 Removed the data_context from the PKCS API.
4440 * Added silc_hmac_register_default function to register default
4441 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4442 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4443 to unregister all hmacs at once.
4445 * Register the default ciphers, hash functions, PKCSs and HMACs
4446 if client's configuration file does not exist. The affected
4449 * The client did not load the hash functions from the SIM
4450 modules at all. Added support for this. Affected file is
4451 silc/clientconfig.c.
4453 * When decoding public key with silc_pkcs_public_key_decode, check
4454 the supported algorithm only if PKCS are registered. Affected
4455 file lib/silccrypt/silcpkcs.c. The same was done with the
4456 silc_pkcs_private_key_decode.
4458 * Fixed the SILC List routines to keep the list always in order.
4459 It used to change the list's order when traversing the list but
4460 not it preserves the order. Affected file lib/trq/silclist.h.
4462 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added the client library to use the SilcSocketConnection's
4465 reference counter (by silc_socket_dup) to prevent the bug that
4466 the socket object may be freed underneath async operation.
4468 * The name resolv library checking fixes in the configure.in.pre.
4471 * Created new version of the protocol drafts for future
4472 development. The -03 drafts are the ones that will be changed
4473 in the trunk now and the -02 will remain as they are.
4475 * Send list of CUMODE notifys to the router when announcing
4476 the channel users to the router. Affected file silcd/server.c.
4477 If the router receiving channel founder CUMODE for a channel
4478 that already has channel founder it will send CUMODE notify
4479 to the sender to remove the channel founder rights from the
4480 announced client. Affected file silcd/packet_receive.c.
4482 * The CUMODE notify may now use Server ID as well as the entity
4483 who changes the mode. Updated protocool specs.
4485 * Updated INSTALL and README files.
4487 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * New web pages in the http://silc.pspt.fi. The pages was
4494 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Implemented the [DenyConnectin] config section in the server.
4497 Added silc_server_config_denied_conn to check whether incoming
4498 connection is denied. Affected file silcd/serverconfig.[ch].
4500 * Do not check the ports when checking the incoming configuration
4501 data if the port is 0, meaning any. Affected file is
4502 silcd/serverconfig.c.
4504 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Fixed buffer overflow in silc_string_compare in the file
4507 lib/silcutil/silcutil.c.
4509 * Fixed double free in silc_server_command_leave in the file
4512 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Fixed the version checking in the server. Affected file is
4517 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Fixed the configuration data fetching when accepting new
4520 connections in the server. Affected file silcd/server.c.
4522 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Added `sender_entry' argument to the function
4525 silc_server_packet_relay_to_channel so that we can check
4526 whether some destination actually belongs to the same route
4527 the sender belongs (ie, we must not resend the packet to the
4528 sender). Affected file silcd/packet_send.[ch].
4530 * Added `servername' field to the SilcClientEntry in the server
4531 to hold the name of the server where client is from. Affected
4532 file is silcd/idlist.h.
4534 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Moved the channel message encrypting in the router betwen
4537 router connections from silc_server_channel_message to the
4538 silc_server_packet_relay_to_channel since we want to check
4539 whether we have anybody channel before encrypting anything.
4540 Affected files silcd/packet_[receive/send].c.
4542 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Fixed the [AdminConnection] server config section to support
4545 multiple entries. Affected file silcd/serverconfig.c.
4547 * Added support into the server to check the validity of the
4548 incoming connection before executing any KE or authentication
4551 * The connection configuration is now saved to the KE and
4552 connection auth protocol contexts and not fetched anymore in
4553 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4555 * The local hosts listenning address and port is also resolved
4556 now when starting the server. We want to have the socket object
4557 to include the real address and port for the listener. Added
4558 new function silc_net_check_local_by_sock into the files
4559 lib/silcutil/silcnet.[ch].
4561 * Fixed a broadcast bug in server -> do not broadcast if we
4564 * Fixed a routing bug. Do not route broadcast packets ever.
4565 Broadcast packets must be processed always and not routed since
4566 they may be destined to some other host than yourself and thus
4567 would get routed without no good reason. Affected file is
4570 * Added function silc_server_config_is_primary_route to check
4571 whether primary router connection has been configured (a router
4572 configuration that we are initiating). If there is not, we
4573 will assume that there is only two routers in the SILC network
4574 and we will use the incoming router connection as our primary
4575 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4577 * Changed the order of the broadcasting. Broadcast _after_ the
4578 packet has been processed not before. Affected file is
4581 * Fixed a [ClientConnection] parsing bug. The port was never
4582 parsed correctly thus resulting to port 0. Affected file
4583 silcd/serverconfig.c.
4585 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4586 argument and did not set the broadcast packet flag. Affected
4587 file silcd/packet_send.c. Fixed same bug in the function
4588 silc_server_send_notify as well.
4590 * If we receive NEW_ID packet for our own ID in the server, ignore
4593 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Removed the nickname from the Private Message Payload.
4598 Updated the code and the protocol specs.
4600 * Updated protocol specs for submitting to the IETF.
4602 * Tweaked the Random Number Generator a bit. Affected file
4603 lib/silccrypt/silcrng.c. Exported a new function
4604 silc_rng_[global]_add_noise which can be used to add more
4607 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Do not parse packets with different timeout when protocol
4610 is active -> may cause problem with rekey. Affected file
4613 * When server receives signoff notify it must not create
4614 new channel key if the client is on any channels since the
4615 sender of the signoff notify will create it.
4617 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Added printing of error messages during SKE protocol from the
4620 failure packet sent by server during SKE. Affected file
4623 * Removed the client's failure_callback handling with timeout
4624 and handle it immediately when received.
4626 * The SKE library returned wrong type in SUCCESS and FAILURE
4627 packets. They must be 32 bit MSB not 16 bit MSB.
4629 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Ok, rewrote the logic of the re-key and now it seems to work.
4632 I tested it on high traffic with frequent re-keys without
4633 problems. Added hmac_receive (and renamed hmac to hmac_send)
4634 in SilcClientConnection in lib/silcclient/client.h and
4635 in SilcIDListData in silcd/idlist.h. Also, removed the
4636 SilcPacketParserContext's cipher and hmac fields as they are
4637 not needed anymore and actually caused some problems when
4638 the ciphers and hmac's changed underneath the packet parser.
4640 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * If re-key protocol is active then process the incoming packets
4643 synchronously since we must assure that icoming packets encrypted
4644 with the old key is processed before the new keys is set to
4645 use. This is true other packets than for REKEY packets.
4646 Affected file silcd/server.c. The same was done to client library
4647 as well, affected file lib/silcclient/client.c.
4649 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Fixed bug in client and server to accept the force send if
4652 the packet is send from silc_[server/client]_packet_process
4653 function. Otherwise the packets are never delivered, oops.
4655 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Disable force sending of packets when REKEY protocol is active.
4658 We must assure that no packet is sent directly when rekey is
4659 performed. All packets must be sent through packet queue.
4660 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4661 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4662 function is silc_[server/client]_packet_send_real to check
4665 * Replaced the SIM paths from example config files to
4666 /usr/local/modules. Also, make install creates now
4667 /usr/local/silc/logs directory to hold all the SILC server
4670 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Made the configure.in.pre work on Solaris. Patch by salo.
4674 * Made all ciphers compatible with non-x86 machines. Defined
4675 CBC mode macros into lib/silccrypt/ciphers_def.h.
4677 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Fixed the make install.
4681 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * When MAC computation fails the silc_packet_decrypt returned 0
4684 even though it was supposed to return -1. Fixed this. The
4685 affected file is lib/silccore/silcpacket.c.
4687 * Do not replace the config files in /etc/silc (in make install)
4688 if they already exist. Affected file ./Makefile.am.
4690 * Do not send re-key packets immediately but through packet queue.
4691 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4693 * Changed silc_net_check_host_by_sock to return FALSE if the
4694 IP/DNS could not be resolved. Though, it returns the IP address
4695 now even if it could not resolve it (but returns also FALSE).
4696 Affected file lib/silcutil/silcnet.[ch].
4698 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Added silc_pkcs_decode_identifier to decode the public key's
4701 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4702 Added also silc_pkcs_free_identifier. Added also new context
4703 SilcPublicKeyIdentifier.
4705 * Added -S option to the silc client. It is used to dump the
4706 contents of the specified public key file.
4708 * Changed the PKCS api to return the public key length when
4709 setting the public key.
4711 * Fixed a fatal bug in the public and private key file loading.
4712 Affected file lib/silccrypt/silcpkcs.c.
4714 * Execute the packet parsing for client with zero (0) timeout
4715 if the protocol is active. Affected file silcd/server.c.
4717 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Made the key generation options to the silcd program. Added
4720 -C option, equivalent to client's option.
4722 * Added new [ServerKeys] config section to the server. It
4723 configures the server's public and private key.
4725 * Defined generic Public Key Payload into the protocol
4726 specification to send specific type of public keys and
4729 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4730 public key or certificate.
4732 * Implemented the GETKEY command to the server and to the
4733 client library and on user interface.
4735 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Made preliminary `make install' work.
4739 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Added SilcServerRekey context into silcd/idlist.h.
4743 * Added the PFS support as defined in the specification to the
4744 SKE protocol. Affected files lib/silcske/*.c.
4746 * Added `ske_group' field to the SilcServerRekey context to hold
4747 the number of the SKE group that is used with PFS in re-key.
4748 Affected file silcd/idlist.h.
4750 * Added PFS re-key support to the server. Affected file is
4753 * Added silc_protocol_cancel to cancel execution of the next
4754 state of the protocol. Affected file is
4755 lib/silccore/silcprotocol.[ch].
4757 * Added the re-key support with and without PFS to the client
4758 library. Re-key is performed once in an hour, by default.
4760 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4761 Added silc_client_rekey_callback and silc_client_rekey_final.
4762 Affected files are lib/silcclient/protocol.[ch] and
4763 lib/silcclient/client.[ch].
4765 * Removed the `hmac_key' and `hmac_key_len' fields from the
4766 SilcClientConnection structure; not needed. Affected file is
4767 lib/silcclient/client.h.
4771 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Do not ask whether user wants to use the negotiated private key
4774 for private messages, just use it. Affected file is
4775 silc/local_command.c.
4777 * Added `send_enc_key' and `enc_key_len' fields to the
4778 SilcIDListData structure since they are needed in the re-key
4779 phase. Affected file is silcd/idlist.[ch].
4781 * Implemented the simple re-key protocol into the server.
4782 Affected files silcd/server.c and silcd/protocol.[ch]. The
4783 re-key will be performed once in an hour, by default.
4785 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4786 Added silc_server_rekey, silc_server_rekey_callback and
4787 silc_server_rekey_final.
4789 * Removed Tunneled flag from the protocol. Updated the code
4790 and the specifications.
4792 * Adde `pfs' field to the SilcIDListData to indicate whether
4793 the PFS is to be performed in the re-key. Affected file is
4796 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4799 int64 of at least the xintXX size. If void * is less that 4
4800 bytes uint32 * will be used. Defined bool as boolean.
4802 * Changed _ALL_ unsigned long and unsigned int to uint32,
4803 unsgined short to uint16 in the source tree.
4805 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4806 not handle clients that has entry->data.registered == FALSE.
4807 They are not in the network anymore. Affected file is
4810 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Implemented the sending of the SERVER_SIGNOFF notify in the
4813 server. Affected file is silcd/server.c.
4815 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4816 Added also silc_notify_payload_encode_args into the
4817 lib/silccore/silcnotify.[ch].
4819 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4820 Affected file silcd/packet_receive.c.
4822 * Implemented the SERVER_SIGNOFF notify handling in the client
4823 library. Affected file lib/silcclient/client_notify.c. Also,
4824 implemnted the printing of the SERVER_SIGNOFF info to the
4825 application. Affected file silc/client_ops.c.
4827 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4828 if the deleting was successful. Affected file silcd/idlist.[ch].
4830 * Added support for public key authentication in the connection
4831 authentication protocol in the client library. Affected file
4832 lib/silcclient/protocol.c.
4834 * Changed the server's silc_idlist_get_clients_by_* interface
4835 to support already allocated array so that new entries may be
4836 added to pre-allocated array. Affected file silcd/idlist.[ch].
4837 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4838 and command replies.
4840 * All command reply functions in the server now calls the
4841 pending command callback even if error occured. This way the
4842 error will be delivered to the client as well. Affected files
4843 silcd/command.c and silcd/command_reply.c.
4845 * Fixed INFO command to return local server's info if no server
4846 was provided. Affected file lib/silcclient/command.c.
4848 * Removed RESTART command for good. Updated the code and the
4851 * Rewrote parts of the task system. It is a bit simpler now.
4852 Removed unsued task priorities. The affected files are
4853 lib/silcutil/silctask.[ch].
4855 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Moved the USERS printing from the library to the application.
4858 Affected files lib/silcclient/command.c and silc/client_ops.c.
4860 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added channel key re-key support. The re-key is perfomed
4865 only by the router and is done once in an hour. Added `rekey'
4866 field to the SilcChannelEntry in the server. Affected files
4867 silcd/server.c and silcd/idlist.h.
4869 * Added silc_task_unregister_by_context into the file
4870 lib/silcutil/silctask.[ch].
4872 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Added SILC_UMODE_GONE mode to indicate when the client is not
4875 present in the SILC network. Added also support to the local
4876 command AWAY that will set this mode. Added support of showing
4877 "xxx is gone" in WHOIS command. The USERS command shows the
4878 gone status as well.
4880 * Fixed setting server and router operator privileges in the
4881 server's UMODE command. Affected file silcd/command.c.
4883 * Merged the SKE KE1 and KE2 payloads into one payload. The
4884 new KE payload is equivalent to the old KE2 payload.
4886 Cleaned up the SKE Start Payload parsing. It now uses the
4887 simple buffer unformatting to do the parsing. A lot faster
4890 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4891 to the SKE that is used to indicate whether both of the SKE
4892 parties should perform authentication. By default only the
4893 responder performs authentication. By setting this flag also
4894 the initiator must do authentication. By default it is unset
4895 since in normal SKE case, client to server connection, only
4896 the responder should do authentication. When doing SKE between
4897 two clients both should perform authentication. Updated the
4898 code and the protocol specs.
4900 * A little fix to IDENTIFY command in the server. Search the
4901 client first by hash not nickname. Affected file is
4904 * Fixed the silc_client_close_connection to support closing
4905 the client to client connections wihtout deleting too much
4906 data. Affected file lib/silcclient/client.c.
4908 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4909 are received if protocol used to be active but is not anymore
4910 the application would crash due to NULL pointer dereference.
4911 Affected files silcd/server.c and lib/silcclient/client.c.
4913 * Added `hash' field to the SilcClientConnection to include
4914 the hash function negotiated in the SKE protocol.
4916 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4917 to set the channel founder authentication data. A client can
4918 claim the founder rights later by providing the authentication
4919 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4920 This way the channel founder can regain the channel founder
4921 privileges even it is left the channel. This works only on
4922 local server and the client must be connected to the same
4923 server to be able to regain the founder rights. Updated the
4924 protocol specs accordingly.
4926 Added support to the CMODE command in the client to set the
4927 founder auth data. Read the README to see how to set it.
4929 Added support to the CUMODE command to claim the founder
4930 rights. Read the README to see how to do it.
4932 Added support for the founder authentication to the Channel
4933 Entry in the server. Affected file silcd/idlist.h.
4935 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4936 server's CMODE command. Affected file silcd/command.c.
4938 * Added the following new functions into lib/silccore/silcauth.[ch]:
4939 silc_auth_get_method and silc_auth_get_data.
4941 * The server now saves the remote hosts public key to the
4942 SilcIDListData pointer. Affected file silcd/protocol.c.
4944 * The normal server now does not remove the channel entry from
4945 the cache if the founder authentication data is set. It used
4946 to remove it if the founder was the last one on the channel on
4947 the server and left the channel. The auth data is saved and
4948 if the channel is re-joined later the old entry is used with
4949 the old auth data. Affected files silcd/command_reply.c and
4952 * Removed the `pkcs' field from the SilcIDListData structure
4953 in the server; it is not used. Affected file silcd/idlist.h.
4955 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Fixed packet processing on slow links. Partial packets were
4958 never re-processed because the incoming data buffer was cleared
4959 by the application. Application must not directly clear the
4960 sock->inbuf, the packet processing routines handle it. Fixed
4961 this in client library and in server.
4963 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Fixed the WHOIS and IDENTIFY send reply function to really
4966 check whether to send list or just one entry. Affected file
4969 * Cleaned up the LEAVE command's channel key distribution. The
4970 affected file silcd/command.c.
4972 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4973 can enforce the channel mode as well. In that case the ID
4974 includes the ID of the server. The code now enforces the
4975 mode change if the router have different mode than the server.
4977 * The notify client operation with CMODE_CHANGE notify can now
4978 return NULL client_entry pointer if the CMODE was not changed
4979 by client. Application must check for this.
4981 * Added <Server ID> argument to INFO command to support server
4982 info fetching by Server ID.
4984 * Added silc_server_announce_get_channel_users to get assembled
4985 packets of channel users of the specified channel. Affected
4986 file silcd/server.[ch].
4988 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4989 was freed underneath the ID Cache.
4991 * Re-announce clients when the server received CHANNEL_CHANGE
4992 notify from the router. Affected file silcd/packet_send.c.
4994 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4997 crashed since it did not handle the fact that there is no cipher
4998 called "3" and didn't check the error condition. Now fixed.
5000 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5001 flag. It can be used to send message requests.
5003 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Implemented the RESTART command in the client.
5007 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5008 notice type messages. Added notice printing to the user
5011 * The channel keys are not re-generated if the channel's mode
5012 is PRIVKEY, ie private key on the channel exists. Affected
5013 files silcd/server.c and silcd/command.c.
5015 * Fixed a little bug in channel message delivery when channel
5016 private keys are set in the server. Affected file is
5017 silcd/packet_send.c.
5019 * Changed the setting on channel->on_channel = TRUE from the
5020 silc_client_save_channel_key to the JOIN command reply. The
5021 key payload is not received if the private channel key is set.
5022 Affected file lib/silcclient/command_reply.c and the
5023 lib/silcclient/client_channel.c.
5025 * When the CMODE_CHANGE notify is sent and the channel private
5026 key mode is removed the channel key must be re-generated in
5027 other cells as well. Added this support for the router in the
5028 silcd/packet_receive.c.
5030 * Added new local command NOTICE to send notice message on
5031 channel. Affected file silc/local_command.[ch].
5033 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Added new local command ME to the client. It is used to send
5036 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5037 some action. Affected file silc/local_command.[ch].
5039 * Changed channel_message and private_message client operations
5040 to deliver the message flags to the application. Added also
5041 the `flags' arguments to the silc_client_send_channel_message
5042 and silc_client_send_private_message functions. Affected file
5045 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Redefined the Private Message Payload to support private message
5048 keys and to support the new private message flags. Updated
5049 the protocol specs. Flags makes it possible to have for example
5050 CTCP style messages.
5052 * Added new type SilcPrivateMessagePayload and defined an API
5053 for it in the lib/silcclient/silcprivate.[ch].
5055 * Tested private message private keys successfully. Tested the
5056 private message key set, unset and list commands with the new
5059 * Redefined the Channel Message Payload to include the channel
5060 message flags (equal with private message flags) to support
5061 for example CTCP style messages.
5063 * Defined some of the message (for channel and private message)
5064 flags. Updated the protocol specs and added the flags to the
5065 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5067 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Added SilcKeyAgreementStatus type to the key agreement routines
5070 to indicate the current status and error if one occured.
5071 The status types are defined in the lib/silcclient/silcapi.h.
5073 * Added new local command KEY that is used to set and unset private
5074 keys for channels, set and unset private keys for private messages
5075 with remote clients and to send key agreement requests and
5076 negotiate the key agreement protocol with remote client. The
5077 key agreement is supported only to negotiate private message keys,
5078 it currently cannot be used to negotiate private keys for channels,
5079 as it is not convenient for that purpose.
5081 * Fixed a minor pending callback setting bug in the function
5082 silc_client_get_client_by_id_resolve, now the function works.
5083 Affected file lib/silcclient/idlist.c.
5085 * Added function silc_net_get_local_port to get local bound
5086 port by socket. Added to lib/silcutil/silcnet.[ch].
5088 * Added `sockets' and `sockets_count' fields to the SilcClient
5089 object. They hold the sockets of the listenning sockets in
5090 the client. Listenning sockets may be for example the key
5091 agreement server. Affected file lib/silcclient/client.[ch].
5092 Added functions the silc_client_add_socket and the
5093 silc_client_del_socket. They are exported to the application
5096 * Added ~./silc/clientkeys to support other client's public keys.
5098 * Renamed verify_server_key client operation to verify_public_key
5099 and added one argument to indicate the type of the connection
5100 (server, client etc.).
5102 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Added silc_server_connection_auth_request to handle the
5105 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5106 silcd/packet_receive.[ch].
5108 * Added silc_server_send_connection_auth_request into the
5109 silcd/packet_send.c to send the connection auth request packet.
5111 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5114 * Fixed the public key authentication in responder side in the
5115 server. The `auth_data' pointer includes the SilcPublicKey
5116 not the path to the public key. Affected file silcd/protocol.c.
5118 * Implemented the public key authentication in the initiator side
5119 in the server. Affected file silcd/protocol.c.
5121 * Removed the [RedirectClient] config section from the server
5122 configuration. Is not needed and I don't want to implement it.
5124 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Cleaned up the CMODE command in the server. It now works
5127 correctly and supports all the modes defined in the protocol.
5128 Affected file is silcd/command.c.
5130 * Added `hmac_name' field to the SilcChannelEntry in the server
5131 to hold the default HMAC of the channel. It can be set when
5132 creating the channel (with JOIN command). Affected files
5135 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5136 type to indicate the change of the current cipher and hmac
5137 on the channel. Client can safely ignore the <cipher> argument
5138 (if it chooses to do so) since the CHANNEL_KEY packet will
5139 force the channel key change anyway. The <hmac> argument is
5140 important since the client is responsible of setting the new
5141 HMAC and the hmac key into use.
5143 * Fixed the CMODE command in the client library as well.
5145 * Tested CMODE command in router environment successfully.
5147 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Show the version of the remote client (or server) when connecting
5150 to the server. It is logged to the log file. Affected file
5151 is silcd/protocol.c.
5153 * Fixed the KILLED notify handling in the client library. The
5154 client must be removed from all channels when receiving the
5157 Also, do not remove the client entry when giving the KILL
5158 command but when the KILLED notify is received.
5160 * Removed silc_idlist_find_client_by_nickname from the server.
5161 Not needed anymore. Affected files silcd/idlist.[ch].
5163 * Implemented the CHANNEL_CHANGE notify type handling to the
5164 server. Affected file silcd/server.c.
5168 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Added silc_server_send_notify_invite to send the INVITE
5171 notify between routers.
5173 * Implemented the INVITE command correctly to the server.
5175 * Implemented the INVITE notify type handling in the server.
5177 * Implemented the INVITE command to the client library and on the
5180 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Added function silc_server_get_client_resolve to find the
5183 client entry by ID from all ID lists and then resolve it
5184 (using WHOIS) if it cannot be found. Affected file is
5187 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Implemented the BAN command to the client library.
5191 * The JOIN command in the server now checks the invite list
5194 * Changed the silc_command_reply_payload_encode_va and the
5195 silc_command_payload_encode_va to support that if argument is
5196 NULL it ignores and checks the next argument. Affected file
5197 lib/silccore/silccommand.c.
5199 * Added silc_server_send_notify_ban to send the BAN notify
5200 type between routers.
5202 * Chaned the silc_notify_payload_encode to support that if
5203 argument is NULL it ignores and checks the next argument.
5204 Affected file lib/silccore/silcnotify.c.
5206 * Tested ban lists in router environment successfully.
5208 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Implemented BAN command to the server, in silcd/command.[ch].
5212 * Removed the BAN and INVITE_LIST modes from the CMODE command
5215 * Added function silc_string_match to regex match two strings.
5216 Affected files lib/silcutil/silcutil.[ch].
5218 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Redefined parts of the SilcChannelEntry in the server to support
5221 the new ban and invite lists.
5223 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Redefined the INVITE command. The same command can be used to
5226 invite individuals to the channel but also to manage the invite
5227 list of the channel (to add to and remove from the invite list).
5228 Updated the protocol specs.
5230 * Added new command SILC_COMMAND_BAN that can be used to manage
5231 the ban list of the channel. Updated the protocol specs.
5233 * Removed the channel modes: the SILC_CMODE_BAN and the
5234 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5235 in the CMODE command. The equivalent features are now available
5236 using INVITE and BAN commands. Updated the protocol specs.
5238 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5239 in the network about change in the current ban list. The notify
5240 type is not used by the client.
5242 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5243 support the invite lists.
5245 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Added new function silc_string_regexify that converts string
5248 including wildcard characters into regex string that can
5249 be used by the GNU regex library. Added into the file
5250 lib/silcutil/silcutil.[ch].
5252 Added silc_string_regex_combine to combine to regex strings
5253 into one so that they can be used as one regex string by
5254 the GNU regex library. Added into the file
5255 lib/silcutil/silcutil.[ch].
5257 Added silc_string_regex_match to match two strings. It returns
5258 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5260 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Imported GNU regex to the soruce tree into lib/contrib.
5263 Fixed some compiler warning from the regex.c.
5265 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Fixed MOTD command in the server to work in router environment.
5269 * Fixed the MOTD command in the client library to support
5270 the server argument in the command.
5272 * Added `nickname_len' argument to the silc_idlist_add_client
5273 in the server, as the `nickname' argument may be binary data
5276 * Added silc_idlist_get_channels to return all channels from
5279 * Implemented LIST command to the server. Affected file is
5282 * Implemented the LIST command to the client library and on the
5285 * Added [<user count>] argument to the LIST command reply.
5286 With private channels the user count is not shown.
5288 * Updated TODO and README.
5290 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * The client entry's data.registered must be TRUE even with
5293 global client entry on global client list. The data.registered
5294 is used to check whether the client is anymore in the network,
5295 for example with WHOWAS command so it must be valid.
5297 * Fixed the WHOWAS command in the server. It now actually works
5298 in router environment. Added function into silcd/command_reply.c
5299 silc_server_command_reply_whowas_save.
5301 * Added silc_idlist_purge function to the silcd/idlist.c
5302 to periodically purge the ID Cache.
5304 * Fixed INFO command in the server. It works now in router
5305 environment. Added <server name> argument to the INFO command
5306 reply. Updated the protocol specs.
5308 * Fixed minor bug in silc_idcache_purge to not purge if the
5309 expire value is zero.
5311 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5312 they were buggy because of the WHOWAS information.
5314 * Fixed local command MSG to handle the async resolving of
5315 the remote client properly. It used to fail the first MSG.
5316 Affected file silc/local_command.c.
5318 * Added `data_len' field to SilcIDCache context.
5320 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Update TODO. Todo in commands in the server.
5324 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5327 used by routers as broadcast packet to inform other routers
5328 about the changed user mode.
5330 Implemented the notify handling in the server. Affected file is
5331 silcd/packet_receive.c. Added the function
5332 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5334 * Added new generic Channel Payload and deprecated the New Channel
5335 Payload. The New Channel Payload is now the generic Channel
5338 * Added new argument `mode' to the silc_server_send_new_channel
5339 as it is required in the Channel Payload now.
5341 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5342 and created a new and real SilChannelPayload to represent the
5343 new generic Channel Payload. Implemented the encode/decode
5344 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5346 * Added silc_server_get_client_channel_list to return the list
5347 of channels the client has joined for WHOIS command reply.
5348 Affected file silcd/server.[ch].
5350 * Implemented the channel list sending in the WHOIS command reply
5351 in server and in the client.
5353 Implemented the channel list displaying on the user interface
5354 as well. Affected file silc/client_ops.c.
5356 * Added silc_channel_payload_parse_list to parse list of Channel
5357 Payloads. It returns SilcDList list of SilcChannelPayloads.
5358 Client for example can use this function to parse the list of
5359 channels it receives in the WHOIS command reply. The caller
5360 must free the list by calling silc_channel_payload_list_free.
5361 Affected files lib/silccore/silcchannel.[ch].
5363 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Added one new argument <user mode> to the WHOIS command reply
5366 to return the mode of the user in SILC. Updated the protocol
5369 Implemented it to the server and client.
5371 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Fixed the mode printing on the user interface on joining.
5374 Affected file silc/client_ops.c.
5376 * Implemented the UMODE command and user modes in general to the
5377 client library and to the user interface.
5379 * Implemented the UMODE command to the server.
5381 * The server now sends UNKNOWN_COMMAND error status if client sends
5382 unknown command. Affected file silcd/command.c.
5384 * All server commands now handle the command identifier the right
5385 way when sending the command reply to the client. The client can
5386 use to identify the command replies with the identifier.
5388 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Added silc_server_get_client_route to resolve the route to
5391 the client indicated by the client ID. Affected file is
5394 * Added silc_server_relay_packet as general function to relay
5395 packet to arbitrary destination. This deprecates functions
5396 like _send_private_message_key, _relay_notify etc. Affected
5397 file is silcd/packet_send.[ch].
5399 Removed silc_server_send_key_agreement,
5400 silc_server_send_private_message_key and
5401 silc_server_packet_relay_notify functions from the file
5402 silcd/packet_send.[ch].
5406 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5407 server. Affected file silcd/packet_receive.[ch].
5409 * Implemented the KILL command to the client. Implemented the
5410 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5411 Affected files lib/silcclient/command[_reply].c and
5412 lib/silcclient/client_notify.c. Implemented the KILL notify
5413 printing in the user inteface.
5415 * Fixed a lot silc_parse_nick memory leaks from the client
5416 library in the file lib/silcclient/command.c.
5418 * Changed the silc_server_send_notify_on_channels's `sender'
5419 argument from SilcSocketConnection to SilcClientEntry to
5420 check the sender as entry and not as connection object and not
5421 to send to the client provided as argument. The affected file
5422 is silcd/packet_send.[ch].
5424 * The notify packets that are destined directly to the client used
5425 to not to be processed by the server. Now changed that and the
5426 server processes all notify packets. After relaying the packet
5427 to the client the notify packet is processed in the server.
5429 * The silc_server_free_client_data now checks whether there is
5430 pending outgoing traffic for the client and purges the data to
5431 the network before removing the client entry.
5433 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5436 an client is killed from the SILC Network. Updated the protocol
5439 Added new function silc_server_send_notify_killed to the
5440 silcd/packet_send.[ch].
5442 * Added function silc_server_packet_relay_notify to relay notify
5443 packets that are destined directly to a client. In this case
5444 the server does not process the notify packets but merely relays
5445 it to the client. Affected file silcd/packet_send.[ch].
5447 Added also silc_server_packet_process_relay_notify to check
5448 whereto relay the notify. Affected file is
5449 silcd/packet_receive.[ch].
5451 * Implemented the KILL command to the server.
5455 * Added the backup schema desgined last fall to the protocol
5456 specs for everyone to see. The specification is in the
5457 *-spec-xx.txt draft and the packet type definitions for the
5458 backup routers is in *-pp-xx.txt draft. Thusly, added also
5459 new packet type SILC_PACKET_CELL_ROUTERS.
5461 * A big security problem in the implementation discovered. The
5462 signoff of an client did not cause new channel key generation
5463 which it of course should've done. The channel keys must be
5464 always re-generated when client leaves (or signoffs) the channel.
5465 The silc_server_remove_from_channels funtion now handles
5466 the channel key re-generation.
5468 * Added `sender' argument to the silc_server_send_notify_on_channels
5469 to not to send the client provided as argument. Affected file
5470 silcd/packet_send.[ch].
5472 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Implemented OPER and SILCOPER commands into the server and
5477 * Added silc_auth_verify and silc_auth_verify_data to verify
5478 the authentication directly from the authentication payload.
5479 It supports verifying both passphrase and public key based
5480 authentication. Affected file lib/silccore/silcauth.[ch].
5482 * Added `hash' field to the SilcIDListData structure. It is the
5483 hash negotiated in the SKE protocol. Affected file is
5486 * Slight redesigning of the SilcAuthPayload handling routines.
5487 Do not send SilcPKCS but SilcPublicKey as argument.
5489 * Implemented the public key authentication support to the
5490 serverconfig. The public key is loaded from the provided path
5491 and saved as authentication data to void * pointer. Thus,
5492 changed the unsigned char *auth_data to void *auth_data;
5494 * Fixed SHUTDOWN command to send the reply before the server
5495 is shutdown. :) Affected file silcd/command.c.
5497 * Fixed fatal bug in CONNECT command. The hostname was invalid
5498 memory and server crashed. Affected file silcd/command.c.
5500 * Fixed fatal bug in CLOSE command. The server_entry became
5501 invalid but was referenced later in the command. Affected file
5504 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Fixed fatal bug in failure packet handling. Server ignored
5507 the failure and thus crashed when it came.
5511 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5514 that the command may be executed only once in (about) 2 seconds.
5515 The old SILC_CF_LAG flag is same but allows command bursts up
5516 to five before limiting.
5518 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5519 server code. Various commands now includes the CF_LAG_STRICT
5520 flag to disallow any kind of miss-use of the command.
5522 * Fixed the silc_buffer_unformat to not to allocate any data
5523 if the length of the data is zero. It used to allocate the
5524 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5526 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Changed the format of AdminConnection configuration section
5529 in the server. Added username of the admin to the format.
5530 Affected files silcd/serverconfig.[ch].
5532 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5533 to return admin configuration data by host, username and/or
5536 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Implemented WHOWAS command to the server. Added the functions:
5540 silc_server_command_whowas_parse,
5541 silc_server_command_whowas_send_reply,
5542 silc_server_command_whowas_from_client and
5543 silc_server_command_whowas_from_server
5545 * Added <Client ID> argument to the WHOWAS command reply. Updated
5546 the protocol specs accordingly.
5548 * Implemented WHOWAS command and command_reply to the client
5551 Implemented the WHOWAS printing on the user interface.
5553 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added new argument to the WHOWAS command reply, the real name.
5556 It is an optional argument. Updated the protocol specs.
5558 * Added SilcIDCacheDestructor callback that is registered when
5559 the SilcIDCache is allocated. The callback is called when
5560 an cache entry in the ID Cache expires, or is purged from the
5561 cache. Added into lib/silccore/idcache.[ch].
5563 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5564 to destruct the client entries when the cache entry expires.
5565 Other ID Cache's in server and in the client library ignores
5568 * If the ID Cache entry's `expire' field is zero then the entry
5569 never expires. Added boolean `expire' argument to the
5570 silc_idcache_add function in the lib/silccore/idcache.[ch].
5571 If it is TRUE the default expiry value is used.
5573 * Added silc_server_free_client_data_timeout that is registered
5574 when client disconnects. By default for 5 minutes we preserve
5575 the client entry for history - for WHOWAS command.
5577 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Added support to the server to enforce that commands are not
5580 executed more than once in 2 seconds. If server receives
5581 commands from client more frequently, timeout is registered
5582 to process the commands. Affected file silcd/command.c.
5583 Added new function silc_server_command_process_timeout.
5585 * Changed NICK_NOTIFY handling in client library to check that
5586 if the client's nickname was changed, so there is no need to
5587 resolve anything from the server.
5589 * Removed error printing from the WHOIS and IDENTIFY commands.
5590 If error occurs then it is ignored silently in the client library.
5591 The application, however, may map the received error to
5592 human readable error string. The application currently maps
5593 the NO_SUCH_NICKNAME error to string.
5595 * Made the command status message public to the application. Moved
5596 them from lib/silcclient/command_reply.c to
5597 lib/silcclient/command_reply.h. The application can map the
5598 received command status to the string with the
5599 silc_client_command_status_message function.
5601 * Added check to the server to check that client's ID is same
5602 as the Source ID in the packet the client sent. They must
5605 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Added dist-bzip hook to the Makefile.am to make bzip2
5608 compressed distributions.
5610 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Server now enforces the maximum length for the nickname and
5613 the channel as protocol specification dictates. 128 bytes for
5614 nickname and 256 bytes for channel name.
5616 * Moved the WHOIS printing to the application. The client libary
5617 does not print out the WHOIS information anymore, the application
5618 must do it. Renamed silc_client_command_reply_whois_print to
5619 the silc_client_command_reply_whois_save.
5621 The client's idle time is also sent to the application now, and
5622 the idle is shown on screen.
5624 * Added silc_client_command_reply_identify_save to save the
5625 received IDENTIFY entries.
5627 * Do not check for channel private keys in message sending and
5628 reception if the channel does not have the PRIVKEY mode set.
5629 Affected file lib/silclient/client_channel.c.
5631 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5634 just surfaced after chaning the JOIN procedure.
5636 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Added silc_client_get_clients_by_list to get client entries
5639 from Client ID list, that is returned for example by JOIN
5640 and USERS command replies. The application should use this
5641 function for example when JOIN command reply is received to
5642 resolve the clients already on the channel (library does not
5643 do that anymore as USERS command reply is not used in the JOIN
5644 procedure anymore). Affected files lib/silcclient/silcapi.h and
5645 lib/silcclient/idlist.c.
5647 * JOIN command reply and USERS command reply returns now SilcBuffer
5648 pointers instead of unsigned char pointers when returning
5649 the client list and mode list.
5651 * Added <Client ID> argument to the JOIN command reply, mainly
5652 for the server to identify for which client the command was
5653 originally sent. Updated protocol specs accordingly.
5655 * Added SilcDlist private_key pointer to the SilcChannelEntry
5656 in the client to support the channel private keys. Affected
5657 file is lib/silcclient/idlist.h.
5659 * Added SilcChannelPrivateKey argument to the function
5660 silc_client_send_channel_message so that application can choose
5661 to use specific private ke if it wants to. If it is not provided,
5662 the normal channel key is used, unless private keys are set.
5663 In this case the first (key that was added first) is used
5664 as the encryption key.
5666 * Implemented the support for channel private key handling.
5667 Implemented the following functions:
5669 silc_client_add_channel_private_key,
5670 silc_client_del_channel_private_keys,
5671 silc_client_del_channel_private_key,
5672 silc_client_list_channel_private_keys and
5673 silc_client_free_channel_private_keys
5675 Affected file lib/silcclient/client_channel.c.
5677 * Added the support for the private keys in the channel message
5678 sending and encryption and in the message reception and
5679 decryption. Affected funtions are
5680 silc_client_send_channel_message and silc_client_channel_message.
5682 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Added SKE's key verify callback to the client library's
5685 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5687 * Removed the statement that server (or router) must send USERS
5688 command reply when joining to the channel so that the client
5689 knows who are on the channel. Instead, the client list and
5690 client's mode list is now sent in the JOIN command reply to the
5691 client who joined channel. This is better solution.
5693 * Added function silc_server_get_users_on_channel and function
5694 silc_server_save_users_on_channel to the silcd/server.[ch].
5696 * Removed function silc_server_command_send_users from the
5699 * Do not show topic on the client library anymore. The topic is
5700 sent in the command reply notify to the application and the
5701 application must show the topic now.
5703 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Added client searching by nickname hash into the IDENTIFY and
5706 WHOIS commands in the server as they were clearly missing from
5707 them. Affected file is silcd/command.c.
5709 * Fixed a bug in private message receiving in the client library.
5710 The remote ID was freed and it wasn't supposed, now it is
5713 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Minor fix to the channel payload; allocate the data area, as it
5716 needs to be of specific length.
5718 * If the key agreement port is zero then the operating
5719 system will define the bound port. Affected files are
5720 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5722 * Added new function silc_channel_payload_decrypt into the file
5723 lib/silccore/silcchannel.[ch].
5725 * Moved the channel message etc, check from silc_packet_decrypt
5726 to applications. The library calls now a generic
5727 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5728 when the packet is either normal or special. This was done to
5729 allow more wide range of checking that was not allowed when
5730 the code was in library. Now applications can do virtually any
5731 checks to the packet and return to the library the decision how
5732 the packet should be processed. Affected files are
5733 lib/silccore/silcpacket.[ch].
5735 Added silc_server_packet_decrypt_check to the server and
5736 silc_client_packet_decrypt_check to the client library.
5738 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5739 to send with specified source and destination information.
5741 * Channel message delivery between routers was broken after the
5742 channel key distribution was fixed earlier. The channel key
5743 was used be to distributed to other routers as well which is not
5744 allowed by the protocol. Now this is fixed and channel keys
5745 really are cell specific and the channel message delivery between
5746 routers comply with the protocol specification.
5748 * Fixed various commands in server to check also the global list
5749 for the channel entry and not just the local list. The affected
5750 file silcd/command.c.
5752 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Added assert()s to buffer formatting and unformatting routines
5755 to assert (if --enable-debug) when error occurs. Affected
5756 file: lib/silcutil/silcbuffmt.c.
5758 * Changed to auto-reconnect to check whether the remote host is
5759 router and register the re-connect timeout if it is. It used
5760 to check that whether we are normal server, but router must do
5761 auto-reconnect with another router as well. Affected file
5764 * Removed the [<key len>] option from CMODE command as the cipher
5765 name decides the key length, nowadays. See the defined ciphers
5766 from the protocol specification.
5768 * Added [<hmac>] option to the CMODE command to define the HMAC
5769 for the channel. Added SILC_CMODE_HMAC channel mode.
5771 * Added [<hmac>] option for the JOIN command so that user can
5772 select which HMAC is used to compute the MACs of the channel
5775 * Added Hmac field to the Channel Message Payload. The integrity
5776 of plaintext channel messages are now protected by computing
5777 MAC of the message and attaching the MAC to the payload. The
5778 MAC is encrypted. Now, it is clear that this causes some
5779 overhead to the size of the packet but rationale for this is that
5780 now the receiver can verify whether the channel message decrypted
5781 correctly and also when private keys are set for the channel the
5782 receiver can decrypt the packet with several keys and check from
5783 the MAC which key decrypted the message correctly.
5785 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5786 lib/silccrypt/silccipher.[ch].
5788 * Added silc_hash_len to return the digest length into the
5789 lib/silcrypt/silchash.[ch].
5791 * Rewrote parts of Silc Channel Payload interface in the
5792 lib/silccore/silcchannel.[ch]. The encode function now also
5793 encrypts the packet and parse function decrypts it.
5795 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Fixed a minor formatting bug in the SKE's key material processing.
5798 It actually might have processed the keys wrong way resulting
5801 * Redefined the mandatory HMAC algorithms and added new algorithms.
5802 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5803 and hmac-md5 truncated to 96 bits. The mandatory is now
5804 hmac-sha1-96. Rest are optional (including the one that used
5805 to be mandatory). Rationale for this is that the truncated HMAC
5806 length is sufficient from security point of view and can actually
5807 make the attack against the HMAC harder. Also, the truncated
5808 HMAC causes less overhead to the packets. See the RFC2104 for
5811 * Added new [hmac] configuration section. The SKE used to use
5812 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5813 is of course wrong. The official names that must be proposed in
5814 the SKE are the ones defined in the protocol specification
5815 (hmac-sha1-96 for example). The user can configure any hmac
5816 using any hash function configured in the [hash] section. At
5817 least, the mandatory must be configured.
5819 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5821 * Added HMAC list to the SKE proposal list. It has now both
5822 hash algorithm list and HMAC list. This makes the protocol
5823 incompatible with previous versions. The SKE now seems to work
5824 the way it is supposed to work, for the first time actually.
5826 * Defined plain Hash algorithms to the protocol specification.
5829 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Implemented support for key agreement packets into the server.
5832 Added functions silc_server_key_agreement and
5833 silc_server_send_key_agreement. Other than these functions,
5834 server has nothing to do with this packet.
5836 * Added support for private message key packets into the server.
5837 Added functions silc_server_private_message_key and
5838 silc_server_send_private_message_key.
5842 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5843 called in the protocol's final callback instead in the END
5844 protocol state. This makes a little more sense and in the same
5845 time in client we can use the same protocol routines for normal
5846 key exchange and to key agreement packet handling as well.
5848 * Added to both client's and server's KE protocol context the
5849 SilcSKEKeyMaterial pointer to save the key material. We will
5850 bring the key material to the protocol's final callback by doing
5851 this. The final callback must free the key material.
5853 * Added SKE's packet_send callback into client's KE protocol
5854 context so that the caller can choose what packet sending function
5855 is used. This way we can use different packet sending when
5856 doing normal SKE when doing key agreement packet handling (in
5857 the key agreement packet handling we do not want to encrypt
5860 * Implemented the responder side of the key agreement routines
5861 in the client. The client can now bind to specified port and
5862 accept incoming key negotiation. The key material is passed
5863 to the application after the protocol is over.
5865 * Implemented the processing of incoming Key Agreement packet
5866 in the client. Added function silc_client_key_agreement to
5869 * Implemented the intiator side of the key agreement routines
5870 in the client. The client can now initiate key agreement with
5871 another remote client. The key material is passed to the
5872 application after the protocol is over.
5874 * Created client_keyagr.c to include all the key agreement
5877 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5878 SILC_TASK_CALLBACK except that it is not static.
5880 * Created client_notify.c and moved the Notify packet handling
5881 from the client.[ch] into that file.
5883 * Created client_prvmsg.c and moved all private message and
5884 private message key routines from the client.[ch] into that file.
5886 * Create client_channel.c and moved all channel message and
5887 channel private key routines from the client.[ch] into that file.
5889 * Changed silc_client_get_client_by_id_resolve to resolve with
5890 WHOIS command instead of IDENTIFY command, in the file
5891 lib/silclient/idlist.c.
5893 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Implemented the SKE's responder side to the Client library.
5897 * When FAILURE is received to the protocol do not trust it
5898 blindly. Register a timeout to wait whether the remote closes
5899 the connection as it should do it, only after that process the
5900 actual failure. This was changed to both client and server.
5902 * Added client_internal.h to include some of the structures
5903 there instead of client.h in lib/silcclient/.
5905 * Added function silc_task_unregister_by_callback to unregister
5906 timeouts by the callback function.
5908 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Some "Incomplete WHOIS info" errors has been appearing on the
5911 log files. Took away the entry->userinfo check from WHOIS
5912 reply sending. The entry->userinfo is now " " if client did not
5913 provide one. I thought this was fixed earlier but something
5914 is wrong still. Let's see if the error still appears.
5916 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Fixed a minor bug in the login when the channel key is
5919 re-generated in the server. It used to generate the key in
5920 wrong order and thus caused problems in the channel traffic.
5922 * Fixed a minor bug in channel key distsribution after
5923 KICK command. The key was not sent to the router even though
5926 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5928 * Added silc_ske_process_key_material_data as generic routine
5929 to process any key material as the SILC protocol dictates. The
5930 function is used by the actual SKE library but can be used by
5931 applications as well. This relates to the private message keys
5932 and the channel private keys since they must be processed the
5933 same way the normal SILC session keys. The protocol dictates
5934 this. Affected files: lib/silcske/silcske.[ch].
5936 Added also silc_ske_free_key_material to free the
5937 SilcSKEKeyMaterial structure.
5939 * Defined silc_cipher_set_key function to set the key for
5940 cipher without using the object's method function. The affected
5941 files: lib/silccrypt/silccipher.[ch].
5943 * Implemented silc silc_client_add_private_message_key,
5944 silc_client_add_private_message_key_ske,
5945 silc_client_del_private_message_key,
5946 silc_client_list_private_message_keys and
5947 silc_client_free_private_message_keys functions in the
5950 Added functions silc_client_send_private_message_key to send
5951 the Private Message Key payload and silc_client_private_message_key
5952 to handle incoming Private Message Key payload.
5954 * Added Cipher field to the Private Message Key payload to set
5955 the cipher to be used. If ignored, the default cipher defined
5956 in the SILC protocol (aes-256-cbc) is used.
5958 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Removed lib/silcclient/ops.h file.
5962 Redefined parts of the SILC Client Library API. Created new
5963 file silcapi.h that deprecates the ops.h file and defines the
5964 published Client Library API. Defined also private message key
5965 API and channel private key API into the file.
5967 This is the file that the application must include from the
5968 SILC Client Library. Other files need not be included by
5969 the application anymore.
5971 * Added new key_agreement client operation callback and also
5972 defined the Key Agreement library API for the application.
5974 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5977 is used by clients to request key negotiation between another
5978 client in the SILC network. If the negotiation is started it
5979 is performed using the SKE protocol. The result of the
5980 negotiation, the secret key material, can be used for example
5981 as private message key.
5983 Implemented the Key Agreement payload into the files
5984 lib/silccore/silauth.[ch].
5986 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Redefined ciphers for the SILC protocol. Added some new ciphers
5989 and defined the key lengths for the algorithms. Changed the
5990 code accordingly. The default key length is now 256 bits.
5992 * Fixed SKE key distribution function silc_ske_process_key_material
5993 when the key length is more than 128 bits. The default key
5994 length in SILC is now 256 bits.
5996 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5997 to indicate unsupported algorithm.
5999 * Renamed rijndael.c to aes.c and all functions as well.
6001 * Fixed a long standing channel key setting bug in client library.
6002 Weird that it has never surfaced before.
6004 * Fixed bug in channel deletion. If the entire channel is removed
6005 then it must also delete the references of the channel entry
6006 from the client's channel list as the client's channel entry and
6007 the channel's client entry share same memory.
6009 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Implemented CONNECT and SHUTDOWN commands in the client.
6013 * Implemented CLOSE command to the client.
6015 * Added the function silc_idlist_find_server_by_name into the
6016 files silcd/idlist.[ch].
6018 Added the function silc_idlist_find_server_by_conn into the
6019 files silcd/idlist.[ch].
6021 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * DIE command was renamed to SHUTDOWN. Updated the both code
6026 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6027 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6029 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6032 * Added function silc_server_create_connection function to create
6033 connection to remote router. My server implementation actually
6034 does not allow router to connect to normal server (it expects
6035 that normal server always initiates the connection to the router)
6036 so the CONNECT command is only good for connecting to another
6039 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6042 or some other client was kicked from the channel.
6044 Implemented the handling of the notify type to both client
6047 Implemented silc_server_send_notify_kicked to send the KICKED
6048 notify. It is used to send it to the server's primary router.
6050 * Implemented the KICK command into server and client.
6052 * Added `query' argument to the silc_idlist_get_client function
6053 to indicate whether to query the client from server or not if
6056 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6057 to indicate that the client is not channel founder.
6061 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Removed the rng context from SilcPacketContext structure and
6064 changed that the packet routine uses the Global RNG API.
6066 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Added support for quit message that client can "leave" on the
6069 channel when it quits the SILC. It is ditributed inside the
6070 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6072 Added silc_server_free_client_data that will take the
6073 signoff message as argument.
6075 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6077 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Updated parts of the protocol specification to keep it up
6082 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6085 payloads in one packet.
6087 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6088 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6089 use now the new List flag.
6091 * Also deprecated the following packet types: REPLACE_ID,
6092 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6094 * Added list support for Notify packet in server.
6096 * Added silc_server_send_notify_channel_change to send the
6097 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6098 the silc_server_send_replace_id.
6100 * Added silc_server_send_notify_nick_change to send the
6101 NICK_CHANGE notify type. Deprecates the function
6102 silc_server_send_replace_id.
6104 * Added silc_server_send_notify_join to send the JOIN notify type.
6105 Deprecates the function silc_server_send_new_channel_user.
6107 * Added silc_server_send_notify_leave to send LEAVE notify type.
6108 Deprecates the function silc_server_send_remove_channel_user.
6110 * Added silc_server_send_notify_cmode and
6111 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6112 types. Deprecates the silc_server_send_set_mode function.
6114 * Added SERVER_SIGNOFF notify type to indicate that server has
6115 quit. This means that all clients on the channel from that
6116 server will drop. This can be also used when netsplit happens.
6118 Deprecated REMOVE_ID packet type since it is not needed anymore
6121 Added silc_server_send_notify_server_signoff to send the
6122 SERVER_SIGNOFF notify type. Deprecates the function
6123 silc_server_send_remove_id.
6125 Added also silc_server_send_notify_signoff to send the
6126 SIGNOFF notify type.
6128 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6129 SILC protocol from this day on. Changed the protocol
6130 specification as well.
6132 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6133 notify type. It is used between routers to notify about
6134 topic changes on a channel.
6136 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6139 * Partly updated the protocol specification to comply with the
6140 changes now made. It is still though a bit outdated.
6142 * The JOIN notify type now takes one extra argument <Channel ID>.
6143 The packet used to be destined to the channel but now the
6144 JOIN type may be sent as list thus it is impossible to
6145 destine it to any specific channel. By adding this argument
6146 it is again possible.
6148 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Added CREDITS file. The CHANGES and CREDITS file will appear
6151 in the distribution as well.
6153 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6156 types in the server's silcd/packet_receive.c.
6158 * Implemented CMODE and CUMODE to work in router environment.
6160 * Fixed minor encoding and decoding buglet from the
6161 lib/silccore/silcmode.c.
6163 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6166 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6168 * Changed all SilcConfigServer* and silc_config_server* to
6169 SilcServerConfig* and silc_server_config*, respectively.
6172 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Associated the ID (client or server ID) to the Authentication
6175 Payload to avoid any possibility of forging. Updated the
6176 protocol specification and the code accordingly.
6178 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * The RSA key length is now save to the RsaKey context in the
6181 key generation process in lib/silccrypt/rsa.c. The key length
6182 is now used to figure out the maximum size of the block allowed
6183 to be encrypted/signed.
6185 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6186 is equivalent to the silc_mp_mp2bin but does not allocate any
6189 * Changed silc_mp_mp2bin API to take length argument. If it is
6190 non-zero then the buffer is allocated that large. If zero, then
6191 the size is approximated using silc_mp_sizeinbase, which however
6194 * Created Global RNG API which is global RNG that application can
6195 initialize. After initializing, any routine anywhere in the
6196 code (including library) can use RNG without allocating a new
6197 RNG object. This was done to allow this sort of use of the
6198 RNG in code that has no chance to allocate RNG object. All
6199 applications currently allocate this and many routines in the
6200 library use this. Affected file lib/silccrypt/silcrng.[ch].
6202 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6203 it to use the Global RNG API.
6205 * Defined Authentication Payload into protocol specification that
6206 is used during SILC session to authenticate entities. It is
6207 used for example by client to authenticate itself to the server
6208 to obtain server operator privileges.
6210 Implemented this payload into the lib/silccore/silcauth.[ch].
6211 Implemented also routines for public key based authentication
6212 as the new protocol specification dictates.
6214 Moved definitions of different authentication methods from
6215 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6217 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6218 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6219 silc_pkcs_verify_with_hash functions into the file
6220 lib/silccrypt/silcpkcs.[ch].
6222 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * The client entry's userinfo pointer must be always valid.
6225 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6226 will fail since it requires the userinfo. Now, the userinfo
6227 is allocated as "" if actual userinfo does not exist. Actually,
6228 it must exist and it is totally Ok to drop client connections
6229 that does not announce the userinfo. However, we will make
6230 this workaround for now.
6232 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6233 to return the remote port by socket.
6235 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6238 SILC_SERVER_PENDING_EXEC and added an new macro
6239 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6240 data or when error occurs while processing the pending command.
6242 Added new argument `destructor' into silc_server_command_pending
6243 and to the SilcServerCommandPending object. This destructor is
6244 now called after calling the pending callback or if error occurs
6245 immediately. If error occurs the actual pending callback won't
6246 be called at all - only the destructor. The destructor may be
6247 NULL if destructor is not needed.
6249 All this applies for client library code as well. Similar
6250 changes were made there as well for the pending commands.
6252 In the client, the application must now allocate the
6253 SilcClientCommandContext with the silc_client_command_alloc
6256 * Added reference counter to the SilcServerCommandContext. Added
6257 function silc_server_command_alloc and silc_server_command_dup
6260 Same type of functions added to the client library for the same
6263 * Removed the cmd_ident from IDListData away since it is now
6264 global for all connections. It is the command identifier used
6265 in command sending and with pending commands. The affected file
6268 * Added reference counter to the SilcSocketConnection objecet to
6269 indicate the usage count of the object. The object won't be
6270 freed untill the reference counter hits zero. Currently only
6271 server uses this, and client ignores it. The client must be
6272 set to use this too later. The affected files are
6273 lib/silccore/silcsockconn.[ch]. Added also the function
6274 silc_socket_dup to increase the reference counter.
6276 This was mainly added because it is possible that the socket
6277 is removed underneath of pending command or other async
6278 operation. Now it won't be free'd and proper DISCONNECTING
6279 flags, etc. can be set to avoid sending data to connection that
6280 is not valid anymore.
6282 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6283 the connection. After that it sets SILC_SET_DISCONNECTED.
6284 It is, however, possible that the socket data is not still freed.
6285 The silc_server_packet_process now checks that data is not
6286 read or written to connection that is DISCONNECTED. The socket
6287 get's freed when the reference counter hits zero.
6289 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Changed the client operation API: channel_message operation's
6292 `sender' is now the client entry of the sender, not the nickname
6293 and the `channel' is the channel entry, not the channel name.
6295 In the private_message operation the `sender' is now also the
6296 client entry of the sender not the nickname.
6298 Affected file is lib/silcclient/ops.h and all applications
6299 using the client operations.
6301 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Moved the calling of ops->connect() from connect_to_server_final
6304 into receive_new_id functin since that is the point when the
6305 client is actually allowed to send traffic to network. The
6306 affected file is lib/silcclient/client.c.
6308 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6311 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6312 (if needs broadcasting) instead of broadcasting the packets one
6313 by one which would make a burst in the network traffic.
6315 * Added `broadcast' argument to the functions in silcd/server.[ch]
6316 silc_server_create_new_channel[_with_id] to indicate whether
6317 to send New Channel packet to primary router.
6319 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Added new function into the silcd/server.[ch] files:
6322 silc_server_create_new_channel_with_id to create new channel with
6323 already existing Channel ID.
6325 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6326 lib/silccore/silcpacket.h. This packet is used t send list of
6327 Set Mode payloads inside one packet. Server uses this to set
6328 the modes for the channels and clients on those channels, that it
6329 announced to the router when it connected to it. The protocol
6330 specification has been updated accordingly.
6332 * The silc_server_new_channel did not handle the packet coming
6333 from normal server as it normally does not send that. However,
6334 when it announces its channels it does send it. Implemented
6335 the support for that.
6337 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6338 into the file lib/silccore/id.h.
6340 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Fixed memory leaks in the functions silc_idlist_del_client,
6343 silc_idlist_del_channel and silc_idlist_del_server in the file
6344 silcd/idlist.c. All of those leaked like a sieve.
6346 * Fixed some small memory leaks in the client's function
6347 silc_client_notify_by_server.
6349 * Added functions into silcd/server.c: silc_server_announce_clients,
6350 silc_server_announce_channels and silc_server_announce_server.
6351 These functions are used by normal and router server to announce
6352 to its primary router about clients, channels and servers (when
6353 router) that we own. This is done after we've connected to the
6356 These functions effectively implements the following packet types:
6357 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6358 and SILC_PACKET_NEW_ID_LIST.
6360 * Added new functions into the silcd/packet_receive.[ch]:
6361 silc_server_new_id_list, silc_server_new_channel_list and
6362 silc_server_new_channel_user_list to handle the incoming
6363 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6365 * Added support of changing Channel ID in the function
6366 silc_server_replace_id. If the server that announces a channel
6367 to the router already exists in the router (with same name but
6368 with different Channel ID), router is responsible to send
6369 Replace ID packet to the server and force the server to change
6370 the Channel ID to the one router has.
6372 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6373 client that the Channel ID has been changed by the router. The
6374 normal server sends this to the client. Client must start using
6375 the new Channel ID as the channel's ID.
6377 Implemented handling of this new type into lib/silcclient/client.c
6378 into the function silc_client_notify_by_server.
6380 * Added new function silc_idlist_replace_channel_id into the files
6381 silcd/idlist.[ch] to replace the Channel ID.
6383 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Call silc_server_command_identify_check always when processing
6386 the IDENTIFY command in silcd/command.c
6388 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6391 send keepalive packets. The packet can be sent by clients,
6392 servers and routers.
6394 Added function silc_socket_set_heartbeat into the file
6395 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6396 If not set, the heartbeat is not performed. The actual
6397 heartbeat is implemented in the low level socket connection
6398 library. However, application is responsible of actually
6401 Added silc_server_send_heartbeat to send the actual heartbeat
6402 packet into silcd/packet_send.[ch]. Server now performs
6403 keepalive with all connections.
6405 * Added silc_task_get_first function into lib/silcutil/silctask.c
6406 to return the timeout task with shortest timeout. There was a bug
6407 in task unregistration that caused problems. TODO has been
6408 updated to include that task system must be rewritten.
6410 * The client library will now resolve the client information when
6411 receiving JOIN notify from server for client that we know but
6412 have incomplete information.
6414 * Rewrote parts of silc_server_remove_from_channels and
6415 silc_server_remove_from_one_channel as they did not remove the
6416 channel in some circumstances even though they should've.
6418 * Encryption problem encountered in server:
6420 The LEAVE command used to send the Channel Key packet to the
6421 router immediately after generating it. However, the code
6422 had earlier sent Remove Channel user packet but not immediately,
6423 ie. it was put to queue. The order of packets in the router
6424 was that Channel Key packet was first and Remove Channel User
6425 packet was second, even though they were encrypted in the
6426 reverse order. For this reason, MAC check failed. Now, this
6427 is fixed by not sending the Channel Key packet immediately but
6428 putting it to queue. However, this is more fundamental problem:
6429 packets that are in queue should actually not be encrypted
6430 because packets that are sent immediately gets encrypted
6431 actually with wrong IV (and thus MAC check fails). So, packets
6432 that are in queue should be encrypted when they are sent to
6433 the wire and not when they put to the queue.
6435 However, the problem is that the current system has not been
6436 designed to work that way. Instead, the packet is encrypted
6437 as soon as possible and left to the queue. The queue is then
6438 just purged into wire. There won't be any fixes for this
6439 any time soon. So, the current semantic for packet sending
6442 o If you send packet to remote host and do not force the send
6443 (the packet will be in queue) then all subsequent packets to the
6444 same remote host must also be put to the queue. Only after the
6445 queue has been purged is it safe again to force the packet
6448 o If you send all packets immediately then it safe to send
6449 any of subsequent packets through the queue, however, after
6450 the first packet is put to queue then any subsequent packets
6451 must also be put to the queue.
6453 Follow these rules and everything works fine.
6455 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * Added new function silc_server_remove_clients_by_server to
6458 remove all client entries from ID list when the server connection
6459 is lost. In this case it is also important to invalidate all
6460 client entires as they hold the invalid server entry. This
6461 fixes fatal bug when server has lost connection and will reconnect
6464 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Made some sanity checks to silc_server_daemonise like to check
6467 whether the requested user and group actually exists.
6469 * Added sanity check to SKE's silc_ske_responder_finish to check
6470 that the public and private key actually is valid.
6472 * Invalidate the client's nickname when receiving Replace ID
6473 packet and the Client ID is being replaced. This means that the
6474 server will query the nickname if someone needs it (client)
6477 * Sort the ID Cache in client library when the ID Cache data
6478 has changed (needs sorting).
6480 * Do not allow for SILC client to create several connections to
6481 several servers. The client does not support windows right now
6482 and generating multiple connections causes weird behaviour.
6484 Irssi-silc client does support windows and can handle several
6485 connections without problems, see: www.irssi.org and SILC plugin.
6487 * Fixed some places where client was added to the IDList. The
6488 rule of thumb is following (in order to get everything right):
6489 If the client is directly connected local client then the
6490 `connection' argument must be set and `router' argument must be
6491 NULL to silc_idlist_add_client function. If the client is not
6492 directly connected client then the `router' argument must
6493 bet set and the `connection' argument must be NULL to the
6494 silc_idlist_add_client function.
6496 * The funtion silc_server_packet_send_local_channel actually did
6497 not check whether the client was locally connected or not. It
6498 does that now. Fixed a bug related to LEAVE command.
6500 * Fixed Remove Channel User payload parsing bug in server's
6501 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6503 * The server's silc_server_save_channel_key now checks also the
6504 global ID list for the channel as it might not be in the local
6505 list. Fixed a bug related to LEAVE command.
6507 * Is this the end of the [<unknown>] buglet that has been lurking
6508 around for a long time? A little for loop fix in server's
6509 silc_server_command_whois_parse that is used by both IDENTIFY
6510 and WHOIS command. At least, this was a clear bug and a cause
6511 of one type of [<unknown>] buglet.
6513 * WHOIS and IDENTIFY commands call the function
6514 silc_server_command_[whois/identify]_check function even if
6515 we are not router server.
6517 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Added --with-gmp configuration option. If set the GMP
6520 is always compiled in the SILC source tree. If not set then
6521 it is checked whether the system has the GMP3 installed. If
6522 it has then the GMP won't be compiled (the system's headers
6523 and library is used), if it doesn't have it then the GMP is
6524 compiled in the SILC source tree.
6526 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Changed RSA private exponent generation to what PKCS #1
6529 suggests. We try to find the smallest possible d by doing
6530 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6531 not security fix but optimization.
6533 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Added new config entry [Identity] to fork the server and run
6536 it as specific user and group. A patch from Bostik.
6538 * Imported Dotconf configuration library into lib/dotconf.
6539 This will be used to create the SILC configuration files later.
6540 It will appear in the distsribution after this commit.
6542 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * A big code auditing weekend happening. Auditing code for
6545 obvious mistakes, bugs and errors. Also, removing any code
6548 Removed files for being obsolete:
6550 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6551 inline in the file lib/silcutil/silcbuffer.h)
6553 o lib/silcutil/silcbufutil.c (the header has inline versions)
6555 Changed code to fix possible error conditions:
6557 o The buffer formatting routines now check that the destination
6558 buffer really has enough space to add the data. This applies for
6559 both buffer formatting and unformatting
6560 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6561 unformatting was changed to accomodate following rules:
6562 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6563 sent to the function while XXX_*STRING will not allocate or copy
6564 the data into the buffer. Instead it sets the pointer from the
6565 buffer into the pointer sent as argument (XXX_*STRING used to
6566 require that the pointer must be allocated already). This change
6567 makes this whole thing a bit more consistent and more optimized
6568 (note that the data returned in the unformatting with XXX_*STRING
6569 must not be freed now). The routines return now -1 on error.
6571 o Tried to find all code that use buffer_format and buffer_unformat
6572 and added return value checking to prevent formatting and
6573 especially unformatting errors and possible subsequent fatal
6576 o Changed ske->x and ske->KEY to mallocated pointers in
6577 lib/silcske/silcske.h. Fixed possible data and memory leak.
6579 o Added return value checking to all *_parse* functions. Fixed
6580 many memory leaks as well.
6582 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6583 so that buffer overflows would not happen. All code now also
6584 checks the return value as it can fail.
6586 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Added reconnection support to server if the normal server looses
6589 its connection to the router (for example if router is rebooted).
6590 The server performs normal reconnection strategy implemented
6591 to the server. Affected file silcd/server.c.
6593 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Added new packet type SILC_PACKET_SET_MODE that is used to
6596 distribute the information about changed modes (for clients,
6597 channels and clients channel modes) to all routers in the
6598 network. Updated the protocol specification accordingly.
6600 Added functions into silcd/packet_send.c and
6601 silcd/packet_receive.c: silc_server_send_set_mode,
6602 silc_server_set_mode.
6604 Added new files silcmode.[ch] into lib/silccore that implements
6605 the encoding and decoding of Set Mode Payload. Added new type
6606 SilcSetModePayload. Moved the definitions of different modes
6607 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6609 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Oops, a little mistake in server's connection authentication
6612 protocol. The protocol is not ended with FAILURE but with
6613 SUCCESS if the authentication is Ok. :) Affected file is
6616 * Implemented NICK_CHANGE notify handling in server in the file
6617 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6618 the local clients on the channel. After the changing nickname
6619 in router environment snhould work and the [<unknown>] nickname
6620 should appear no more.
6622 The silc_server_replace_id function that receives the Replace ID
6623 payload now sends the NICK_CHANGE notify type also in the file
6624 silcd/packet_receive.c
6626 * Changed WHOIS and IDENTIFY command to support the maximum amount
6627 of arguments defined in protocol specs (3328 arguments). This
6628 fixed a bug that caused problems when there were more than three
6631 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Added extra parameter, command identifier, to the
6634 silc_client_send_command so that explicit command identifier
6637 Changed that ID list routines uses specific command identifier
6638 when sending WHOIS/IDENTIFY requests to the server so that they
6639 can be identified when the reply comes back.
6641 Affected files lib/silcclient/command.[ch],
6642 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6644 * Added `sender' argument to silc_server_packet_send_to_channel
6645 to indicaet the sender who originally sent the packet to us
6646 that we are now re-sending. Ignored if NULL. Affected file
6647 silcd/packet_send.[ch].
6649 * Added some server statistics support in silcd/server_internal.h
6650 SilcServerStatistics structure and around the server code. Also
6651 send some nice statistics information when client is connecting
6654 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Fixed channel ID decoding in server's JOIN command reply in
6657 silcd/command_reply.c
6659 * Fixed braodcasting of replace ID payload to not to send it if
6660 we are standalone server in silcd/packet_receive.c.
6662 * Fixed all channel message sending routines to not to send
6663 packets to clients that has router set, since they are routed
6664 separately in the same function earlier. Affects file
6665 silcd/packet_send.c and all channel packet sending functions.
6667 * In USERS reply, res_argv[i] are not allocated, the table
6668 is allocated. Thus changed that free the table, not its
6671 * In server's whois_check and identify_check if the client is
6672 locally connected do not send any WHOIS commands - they are not
6675 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6677 * Fixed some minor bugs in client when sending WHOIS command. The
6678 arguments was in wrong order.
6680 * Removed statis function add_to_channel from server in
6681 silcd/command.c that was previously used with the joining but
6684 * Tested USERS command in router environment successfully with two
6685 routers, two servers and two clients.
6687 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Reorganized the USERS command and command reply in client library
6690 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6691 When the command is given by user we register a pending command
6692 callback that will reprocess the command after the reply has been
6693 received from the server. When reprocessing the packet we then
6694 display the information. Thus, the USERS information is displayed
6695 now in the command callback instead of in the command reply
6696 callback. The processing of the command is same as previously
6697 when server has sent the command reply in the JOINing process.
6699 * Added to USERS command in silcd/command_reply.c to join the client,
6700 we didn't use to know about, to the channel after we've created
6701 a client entry for it. Also, for clienet we did know already still
6702 check whether it is on the channel or not and add it if not.
6704 * Removed silc_server_command_join_notify as the function and its
6707 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Changed the client's pending command handling to the same as the
6710 server's pending command handling. It is also now possible to
6711 execute command reply functions from other command reply
6712 function as the function callbacks for commands and command
6713 replies are one and same. The pending commands are not static
6714 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6715 in client connection context. Thus, pending commands are server
6716 connection specific as it is convenient.
6718 Changed the function silc_client_command_pending and
6719 silc_client_command_pending_del and added new function
6720 silc_client_command_pending_check. Removed the
6721 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6724 * Added cmd_ident, current command identifier, to the client
6725 connection context in lib/silcclient/client.h to keep track on
6726 command identifiers used in command sending. Client's command reply
6727 function handling now supports the mandatory command identifiers.
6729 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6730 funtions in client to fully support pending command callbacks.
6732 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6733 as one of the arguments to the application in the command reply
6736 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6737 before first releasing SILC but came back. Now it is removed again
6738 and should come back nomore. The FORWARDED flag was used only
6739 by the JOINing procedure by forwarding the command packet to router.
6740 Now, the JOINing procedure has been changed to more generic (due
6741 to various router environment issues) and FORWARDED is not needed
6742 anymore for anything. The protocol specification is yet to be
6745 Now, removed silc_server_packet_forward from server and the flag
6746 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6748 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Renamed NAMES command to USERS command. The NAMES was named that
6751 due to historical reasons. Now it is renamed. Also, rewrote
6752 parts of the USERS command. The nickname list is not sent anymore
6753 by the server. Only Client ID and mode lists are sent in the USERS
6754 command. Changed this also to the protocol specification.
6756 The client now resolves the names and stuff after it receives
6757 the USERS list from the server when joining to the channel.
6759 * WHOIS and IDENTIFY commands has been changed to support multiple
6760 Client ID's per command. One can now search for multiple users
6761 in the network by sending only one WHOIS or IDENTIFY command.
6762 Changed the code and the protocol specifications.
6764 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6765 uses silc_server_command_whois_parse to parse the request. */
6767 * If normal server, do not parse the WHOIS and IDENTIFY requests
6768 before sending it to the router. Saves some time.
6770 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Fixed JOIN command on client library. Wrong number of arguments
6773 used to crash the client.
6775 * Added silc_server_channel_has_global function to check whether
6776 channel has global users or not.
6778 * Added silc_server_channel_has_local function to check whether channel
6779 has locally connected clients on the channel.
6781 * The silc_server_remove_from_one_channel now checks whether the
6782 channel has global users or not after given client was removed from
6783 the channel. It also checks whether the channel has local clients
6784 on the channel anymore. If it does not have then the channel entry
6785 is removed as it is not needed anymore.
6787 * The silc_server_notify now checks on JOIN notify whether the joining
6788 client is one of locally connected or global. If it is global then
6789 the channel has now global users on the channel and that is marked
6790 to the channel entry. Also, it now saves the global client to
6791 global list who is joining and JOINs it to the channel. This is
6792 for normal server, that is.
6794 Changed silc_server_send_notify_on_channel,
6795 silc_server_packet_relay_to_channel and
6796 silc_server_packet_send_to_channel check if we are normal server
6797 and client has router set (ie. global client) do not send the
6798 message to that client, as it is already routed to our router.
6800 * Implemented LEAVE notify type handling in silc_server_notify
6803 * Tested LEAVE command in router environment successfully. Tested
6804 with two routers, two servers and two clients.
6808 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6810 * Implemented SIGNOFF notify type handling in silc_server_notify
6813 * silc_server_remove_id now removes the client entry from all channels
6814 it has joined and thusly sends SIGNOFF notify type.
6816 * Rewrote the NAMES list generation in server by removing two excess
6817 loops. The lists are created now inside one loop.
6819 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * silc_server_remove_channel_user checks now also global list
6822 for channel and client.
6824 * silc_server_new_channel_user checks now both local and global
6825 list for channel and client. Fixed a bug in client id decoding.
6826 Used to decode wrong buffer.
6828 * silc_server_channel_message checks now both local and global
6829 list for channel entry.
6831 * Tested channel joining (hence JOIN) in router environment
6832 successfully. Tested with two routers, two servers and two
6835 * Tested channel message sending in router environment successfully.
6837 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Added silc_server_save_channel_key into server.[ch] to save the
6840 received channel key in Channel Key payload processing. It is
6841 also used in JOIN command reply handling.
6843 Equivalent function silc_client_save_channel_key added into
6844 client.[ch] into client library.
6846 * Changed JOIN command reply to send information whether the channel
6847 was created or not (is existing already) and the channel key
6848 payload. Changed protocol specs accordingly.
6850 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6851 the request was sent by ID and not by nickname. Crashed on
6854 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6857 now correctly save the received data.
6859 * silc_server_free_sock_user_data now notifies routers in the
6860 network about entities leaving the network.
6862 At the same time implemented functions silc_server_remove_id
6863 and silc_server_send_remove_id to receive and send REMOVE_ID
6864 packets. The packet is used to notify routers in the network
6865 about leaving entities. The ID removed will become invalid in
6868 * Added function silc_idlist_del_server into server. Removes and
6869 free's server entry from ID list.
6871 * silc_server_private_message function now checks, if we are router,
6872 that the destination ID really is valid ID, naturally.
6874 * In router when NEW_ID packet is received (for new client) the
6875 hash of the Client ID is saved in the ID Cache but the
6876 client->nickname is set to NULL, instead of putting the hash
6879 IDENTIFY command now also checks that client->nickname must be
6880 valid. If it is not if will request the data from the server who
6881 owns the client. Added new function
6882 silc_server_command_identify_check.
6884 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6885 to set the command to already allocated Command Payload.
6887 * Tested private message sending in router environment with two
6888 routers, two servers and two clients. Fixed minor bugs and now
6891 * Fixed segfault from client's NAMES command. Used to crash if
6894 * Forwarded packets must not be routed even if it is not destined
6895 to the receiver. Changed server code comply with this.
6897 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Added `require_reverse_mapping' boolean value to ServerParams
6900 structure. If TRUE (not default) the server will require that
6901 the connecting host has fully qualified domain name.
6903 If the reverse mapping is not required and hostname could not be
6904 found the IP address is used as hostname.
6906 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Implemented version string checking to both client and server.
6909 The check is incomplete currently due to the abnormal version
6910 strings used in development version of SILC.
6912 * Changed all command functions in server to use the new
6915 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6917 * Changed char *data to unsigned char *data in ID Cache system to
6918 support binary data as ID Cache data. Changed code to support
6919 binary data in lib/silccore/idcache.c.
6921 * Renamed silc_server_packet_relay_command_reply to
6922 silc_server_command_reply as it is normal packet receiving
6923 function. Rewrote the function to accept command replys for
6924 servers and not only for clients.
6926 * Mark remote router always as registered server if we are connecting
6927 to it. Otherwise, commands sent by the router to us are ignored.
6929 * All ID List find routines now returns the ID Cache Entry pointer
6930 as well if requested.
6932 * WHOIS command works now in router environment, tested with two
6933 routers, two servers and two clients.
6935 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6936 in router environment (as it is almost equivalent to WHOIS) but
6937 hasn't been tested thoroughly. Added new functions:
6939 silc_server_command_identify_parse
6940 silc_server_command_identify_send_reply
6941 silc_server_command_identify_from_client
6942 silc_server_command_identify_from_server
6944 * Disabled route cache adding because adding two different ID's with
6945 same IP replaces the old cache entry thus giving wrong route.
6946 The entry->router->connection is always the fastest route anyway
6947 so route cache may not be needed. Of course, new routes maybe
6948 established after receiving the ID when the entry->router->connection
6949 might not be anymore the most optimal.
6951 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6953 * Add route cache for received ID for fast routing.
6955 * Added silc_server_packet_route to route received packet on router
6956 that is not destined to us.
6958 * Renamed silc_server_get_route to silc_server_route_get.
6960 * Added id_string and id_string_len fields into SilcServer to
6961 include encoded ServerID for fast comparing without excess
6962 encoding of the ID's.
6964 * Cleaned up WHOIS command on server side. Added following static
6967 silc_server_command_whois_parse
6968 silc_server_command_whois_check
6969 silc_server_command_whois_send_reply
6970 silc_server_command_whois_from_client
6971 silc_server_command_whois_from_server
6973 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6974 arguments in command replies. All command functions should be
6975 updated to use this macro.
6977 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Minor typo fixes on command reply handling on server.
6981 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6983 * Added silc_server_command_add_to_channel internal routine to add
6984 the client to the channel after router has created the channel and
6985 sent command reply to the server.
6987 * Added generic silc_server_send_command to send any command from
6990 * Use static buffer with ID rendering instead of duplicating data.
6992 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Fixed a channel user mode bug when joining to a channel server gave
6995 everybody channel founder rights, oops.
6997 * We mark ourselves as the router of the incoming server connection
6998 if we are router ourselves. This way we can check in some packet
6999 sending functions whether it is locally connected server. For
7000 incoming router connections we put NULL.
7002 * For router sending packets locally means now always sending the
7003 packet cell wide; to local clients and local servers. For normal
7004 server sending packet locally means sending it to only local
7007 * Fixed the JOIN command to really work in router environment. If the
7008 channel is created it is always created by the router. Router is
7009 also responsible of making the initial joining to the channel,
7010 sending JOIN notify to the sending server and distributing
7011 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7012 does not exist server doesn't do anything else but forward the
7013 command to the router which performs everything.
7015 * Added silc_server_send_channel_key function to send the Channel Key
7018 * Added silc_server_create_channel_key to create new channel key. The
7019 channel key is now re-generated everytime someone joins or leaves
7020 a channel, as protocol dictates. Note: channel->key_len is the
7023 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7025 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7026 packet_receive.[ch] to separate packet sending and receiving
7027 routines. The server.[ch] now includes everything else including
7028 actual packet processing (writing and reading data) and other
7031 Renamed silc_server_private_message_send_internal to
7032 silc_server_send_private_message. The routine is still though
7033 used only to relay private messages as server does not send
7034 private messages itself.
7036 Renamed silc_server_new_channel to silc_server_create_new_channel
7037 and added new function sicl_server_new_channel that handles the
7038 incoming New Channel packet. Added also new sending function
7039 silc_server_send_new_channel to send New Channel Payload.
7041 * Added new function silc_server_notify to process incoming notify
7042 packet to the server/router. Server may then relay the notify
7043 to clients if needed.
7045 * Added new function silc_server_new_channel_user to process incoming
7046 New Channel User packet. Router will redistribute the packet and
7047 send JOIN notify to its local clients and locally connected servers
7048 if needed. Normal server will send JOIN notify to its local client
7049 on same channel when received this packet. Added also corresponding
7050 sending function silc_server_send_new_channel_user to sent the
7053 * Added boolean route argument to send_notif_to_channel and
7054 packet_send_to_channel functions to attempt to route the packet
7055 if it is TRUE and send only locally if it is FALSE.
7057 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7059 * silc_server_replace_id now broadcasts the received replace ID
7060 packet if it is not broadcast packet already. The router must
7061 broadcast to inform other routers about changed ID.
7063 * Added backpointer to server's router into SilcServer context in
7064 silcd/server_internal.h.
7066 * Fixed silc_server_packet_broadcast to send correct broadcast
7069 * The channel key is now distributed to the local client as soon
7070 as it is received from the router (in router environment) so that
7071 no other packet may be sent for the channel until client has
7074 * silc_server_remove_channel_user now broadcasts the received
7075 Remove Channel User packet if it is not broadcast packet already.
7076 The router must broadcast to inform other routers about removed
7079 * Added users field into SilcPacketContext that is a reference count
7080 of the context. One can increase the reference count by calling
7081 silc_packet_context_dup which is now changed to just increase the
7082 reference count instead of duplicating the data. The reference
7083 count is decresed by calling silc_packet_context_free that will
7084 free the data after the reference count hits zero.
7086 For now on the packet context and everything allocated into it
7087 (including the raw packet from network) must be freed by calling
7088 the new silc_packet_context_free function. Added also new function
7089 silc_packet_context_alloc that must be used now to allocate the
7090 context. This also means that if a routine is asynchronous from
7091 silc_[client/server]_packet_parse_type the packet context must
7092 be duplicated by calling silc_packet_context_dup. Otherwise it
7093 gets free'd after silc_[client/server]_packet_parse_type returns.
7094 Also, one must remember that if packet is duplicated then its
7095 reference count must be decresed by calling the free function as
7096 many times as it was duplicated.
7098 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7099 from both client and server.
7101 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Made joining to a channel working in router environment.
7105 * Cleaned up JOIN command on server side and create function
7106 silc_server_command_join_channel internal routine to make the
7109 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Changed silc_command_pending list to SilcDList. Also, added
7112 `ident' field to SilcServerCommandPending structure to identify
7113 the reply and to call correct callback.
7115 Added silc_server_command_pending_check function to replace the
7116 corresnponding macro. The silc_command_pending list is not
7119 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7120 to set identifier to previously allocated Command Payload. It
7121 is used to set identifier for command when resending Command
7124 * Added silc_command_payload_encode_payload to encode Command
7125 Payload buffer from SilcCommandPayload structure.
7127 * Added silc_argument_payload_encode_payload to encode Argument
7128 payload buffer from SilcArgumentPayload structure.
7130 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Changed WHOIS command to support router connection on server side.
7133 The whois request is always sent to router unless the server is
7134 standalone server. After server has received the reply from the
7135 router will it send the reply to the client.
7137 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7138 broadcast received broadcast packet. The function is used only
7139 by router. The broadcast packet is always sent to the router's
7142 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7143 render given ID to printable string, for log files for example.
7145 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7147 * Made basic router to router connections working. At least they
7148 can now connect to each other but nothing really works the way
7149 they are supposed - yet.
7151 * Added new initiator token to RouterConnection configuration
7152 file in silcd/serverconfig.[ch]. It is used to tell whether we
7153 are the initiator to the remote router or whether we'll expect
7154 the other end to connect.
7156 * Moved registering of listener task to silc_server_init, hence
7157 the server starts listenning as soon as it is run, even if it
7158 does not have connections to other routers. Let's see how well
7161 * Changed default connection retry timeouts for more suitable in
7164 * Removed cipher and such arguments from silc_idlist_add_client
7165 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7166 Added new function silc_idlist_add_data to add the keys and stuff
7169 * Added SilcIDListData structure and added it to SilcClientEntry
7170 and SilcServerEntry as their first field in the structure. This
7171 way we can explicitly cast the ID entries to the SilcIDListData
7172 structure and get common data for the entries. In past, we had
7173 to first check what type of connection it is and then cast it to
7174 correct ID entry type. Now, we can directly cast the opaque
7175 pointer to the SilcIDListData (no matter what ID entry it actually
7176 is) and get the data needed.
7178 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7181 in some circumstances even if threre were timeout tasks, though not
7182 IO tasks, but tasks anyway. Now fixed.
7184 * Defined SilcServerConnection structure to hold connection specific
7185 stuff about directly connected servers and routers. The definition
7186 is currently in silcd/server_internal.h. I thought about having
7187 a bit more important role fro this struct but for now it is used
7188 only when connecting to other server (or router actually).
7190 * Added connecting retry support in server when connecting to
7191 router(s). The retry feature implement exponential backoff
7192 algorithm. Also, added SilcServerParams structure to hold default
7193 parameters for server. For now, it include these retry settings
7194 and are hard coded. After server is moded to be as Silc Server
7195 Library this structure will be more important.
7197 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Changed client librarys channel->clients table to SilcList and
7200 changed code accordingly.
7202 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7204 * Changed client's channel table to SilcList and changed code
7205 accordingly. Also changed SilcChannelClientEntry to include back-
7206 pointer to the channel so that client entry can use that structure
7207 as list as well and we have fast cross-reference to the channel.
7208 This change dramatically decreased the complexity of channel
7209 handling with client entry and vice versa (removed one extra
7210 loop when searching for channel entry from many functions).
7212 * Changed server->sim from table to SilcDList and changed code
7215 * NAMES command can now be used from user interface. It will show
7216 the user list on the channel, neatly.
7218 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7219 Code now saves realname of the user if it becomes available.
7221 * Renamed configure.in to configure.in.pre and made ./prepare
7222 script to automatically add correct version string to
7223 configure.in which it creates from configure.in.pre.
7225 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * NAMES command reply now shows users mode with the nickname when
7230 * Moved silc_client_ch[u]mode[_char] functions from
7231 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7232 place sucks, they are utility functions and should be in some
7235 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7237 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7240 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * Added TRQ (efficient deque and list library) into lib/trq. This is
7245 a very good list library that is currently used in the SILC. Defined
7246 SilcList API over the library because I didn't like the API very
7247 much. See lib/trq/silclist.h for the API and examples of how to
7248 use the API. Fixed various places in the code to use the new
7249 SilcList API. The SilcList is meant for lists that has a structure
7250 already defined as a list. It is not suitable to add just some
7251 context to the list (in TRQ, the context is the list actually).
7253 So, I defined SilcDList that can be used for the purpose where
7254 predefined list structure does not exit. This can be used as
7255 such list. Now some context just can be added to the SilcDList.
7256 Currently this list is not used in the SILC just yet, though there
7257 are a lot places where this can replace dynamically allocated
7258 tables and I will fix these places, later, to use SilcDList.
7259 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7260 and use TRQ internally).
7262 Also fixed some annoying warning messages that the original TRQ
7263 code generated. Also minor changes to TRQ's Makefile.in.
7265 * Added support for querying by Client ID to both WHOIS and
7266 IDENTIFY commands into server, as required by the protocol.
7268 * Removed method function pointers from SilcBuffer structure. They
7269 weren't used to anything and just increased the context size for
7270 no good reason. This change also made silc_buffer_alloc and
7271 silc_buffer_free functions inline functions.
7273 * Disabled command flooding detection support until it's fixed so
7274 that it accepts commands in but does not execute them more than once
7277 * Added silc_net_localhost(), to return local hostname, into
7278 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7279 that must be initialized before calling silc_client_init.
7281 * Added new function: silc_server_send_notify_on_channels to send
7282 notify messages to all channels client has joined. It is assured
7283 that the message is sent only once per client.
7285 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7286 lib/silcutil/silcutil.[ch] as silc_format function. The new
7287 function is generic and is used by server as well, not only by
7288 the logging routines.
7290 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7291 the provided version string was not acceptable. Added new function:
7292 silc_ske_check_version into lib/silcske/silcske.h. The function
7293 must be implemented by the application (client or server) and it
7294 does not reside in the SKE library. The function checks the version
7295 string remote end sent.
7297 * Added back pointers (to opaque context and to SilcSocketConnection)
7298 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7300 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7301 duplicate packet context structure.
7303 * Changed `notify' client operation to send same arguments as client
7304 receives from server except for ID's. ID's are mapped to correct
7305 ID entry and that is returned. Also, if channel entry is not sent
7306 by server but the notify is for channel the channel entry is sent
7307 to application (otherwise application doesn't know that it is for
7308 channel (library gets it from packet's Destination ID)).
7310 * Added silc_client_remove_from_channels into client library to
7311 remove a client from all channels it has joined to. Used when
7312 received SIGNOFF notify from server. Added also new function
7313 silc_client_replace_from_channels to replace old ID entry with
7314 new ID entry on all channels. Used when received NICK_CHANGE
7317 * Fixed ID Cache list handling in silc_idlist_get_client in
7318 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7319 to get (or query) client by ID.
7321 * Updated TODO list.
7323 * Added connection authentication status message defined by the
7324 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7325 support for these into the code in client and server side.
7327 * Added generic function silc_client_send_command to send any command
7328 with variable argument list. Application should use this function
7329 to send commands if the command functions provided by the library
7330 does not suite for the application's user interface needs.
7332 * Added new `failure' client operation. Application is notified about
7333 received failure packet if client is executing a protocol. In this
7334 case the protocol's execution has failed.
7336 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7337 is required by the protocol.
7339 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7340 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7343 * Added status flag to SilcSKE object to indicate realtime status
7344 of the SKE protocol.
7346 * Application receives now exactly same command reply arguments as
7347 the library receives from server. However, if ID is received the
7348 corresponding ID entry is returned to the application (eg. Client
7349 ID is mapped to correct SilcClientEntry entry and that is returned).
7350 Changed command_reply client operation due to this change.
7352 * Changed all ID's in commands and in command replys as ID Payloads.
7353 Change affected both client and server side codes.
7355 All ID's sent in SILC network (with execption of ID's in SILC
7356 Packet header) are sent in ID Payload to support variable length
7359 * Server now notifies nick changes and notifies all clients on
7360 the channels about the new nickname (about the new Client ID,
7363 * Implemented CMODE command to change channel modes. Supports all
7364 channel modes defined by the protocol specs except ban and invite
7365 lists. (Also, private channel key mode is supported but support for
7366 setting private channel key in client is missing, thus, this mode
7367 has no effect on client side (except that server requires that the
7368 client uses private channel key and normal channel traffic does not
7371 Also, invite mode works per se, but INVITE command does not work
7372 yet correctly, so you can set channel as invite only channel but
7373 inviting clients to the channel does not work (it is yet to be
7374 thought what's the best way to do it).
7376 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7377 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7378 Implemented CUMODE command to change user's mode on the channel.
7379 Supports all modes defined by the protocol specs.
7381 * Added NAMES command reply to return users modes on the channel.
7383 * Removed unnecessary and slow ciphers from lib/silccrypt.
7385 * Set SO_KEEPALIVE option to connection sockets by default.
7387 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7389 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7390 redefined the Notify Payload into protocol specs.
7392 * Added silc_id_payload_parse_id to get ID directly from raw
7395 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7398 accept searching by Client ID as well.
7400 * Added support for LEAVE and SIGNOFF notify types in client library.
7402 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7403 to parse ID Payload from raw data.
7405 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7407 * Added flags parameter into silc_ske_assemble_security_properties
7408 function in lib/silcske/silcske.[ch].
7410 * Changed notify client operation to fit better for notify messages
7411 sent by server. The notify payload received from server is now
7412 passed to the application (after parsing it to SilcNotifyPayload).
7413 It is application's responsibility to retrieve the arguments
7414 from the payload and show the message the way it wants. The message
7415 sent by server is implementation specific.
7417 * Changed public keys to comply with the protocol specification.
7418 Old public keys are not supported anymore and are not compatible.
7420 * Removed nickname from Channel Payload as the latest draft removed
7421 it. The client must resolve the nickname from the NAMES command
7422 reply received when it joined the channel.
7424 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7426 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Fixed some errors in protocol specification drafts.
7430 * Created lib/silccore/silcnotify.c to implement Notify Payload
7431 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7432 generic payloads described by protocol specifications. The file
7433 includes implementations for ID Payload and Argument Payload.
7435 * Changed Command Payload implementation to use the new Argument
7436 Payload. Changed command_xxxx_payload to command_payload_xxxx
7437 to comply with SILC coding conventions.
7439 * Added suppport for Argument Payload handling in Notify Payload
7440 implementation as protocol requires it. Added the new support
7441 into server and client lib as well.
7443 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Added support for multiple nicknames on same channel. [n] is
7446 added locally to the nickname if there are more than one same
7447 nicknames on the channel.
7449 * Server now sends all nicknames that matched WHOIS request.
7450 Client also shows the list received from server.
7452 * Added TOPIC command to client side. User can now set and show
7453 current topic on channel.
7455 * Added MOTD command to client and server. Also, server sends the
7456 motd when client connects to the server.
7458 * Changed version strings to comply ISO 8601.
7460 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7462 * Fixed protocol error handling in client library. It should now
7463 cope even if the SKE fails for some reason.
7465 * Made new protocol specification drafts for submitting to IETF.
7467 * Implemented TOPIC command to server in silcd/command.c.
7469 * Added two new notify types into lib/silccore/silcnotify.h:
7470 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7471 notify nickname change and topic setting/change on a channel.
7473 * API change of command_reply operation in client library. The
7474 application gets now the status type received from server as well.
7476 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7478 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7480 * Cras fixed and optimized the packet handling even further and
7481 it should work now. Minor change to the prototype of function
7482 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7484 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7486 * Added new function into lib/silcutil/silcschedule.[ch]:
7487 silc_schedule_with_fd to select() a specified fd. The function
7488 returns after timeout expires or data arrives or goes. The
7489 function is used by packet routines to wait that all data is
7490 received from network.
7492 * Fixed data reading from network in lib/silccore/silcpacket.c.
7493 The code now assures that all data is read from the fd and then
7494 continues packet processing. This was a bug fix since the code
7495 used to drop some data in some circumstances.
7497 * Added new function into lib/silcclient/client.[ch]:
7498 silc_client_start_key_exchange to start key exchange after
7499 connection has been established to server. The code internally
7500 now uses this funtion but its main purpose was to provide it
7501 for applications that perform their own connecting. After
7502 application has created a connection it merely calls this
7503 function to start the key exchange between client and server.
7504 The library takes care of everything else after that.
7506 Updated also lib/silcclient/README to explain the usage of
7509 * Do not send to application information that connection has
7510 been established. Application gets notified it by connect
7513 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Applied cras's patch to add silc_schedule_one function. The
7516 function runs scheduler once and returns.
7518 * Fixed the scheduler after cras messed it up. The timeout
7519 handling works now as it's supposed to work.
7521 * Added into lib/silccore/ silcnotify.h to include notify
7522 message types support. Changed silc_server_send_notify*
7523 functions, in server.[ch], to support those new notify types.
7524 Added the support for the notify types into client library,
7525 as well. Added new notify client operation into ops.h in
7528 * Changed silc_server_packet_send_to_channel to send normal
7529 packets instead of just channel message packets. The function
7530 is now used to send the notify packets to channels. It is not
7531 used to send channel message packets anymore, as server never
7534 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7535 va_arg()s as it seems to require it nowadays. I guess, if SILC
7536 is compiled with older va_arg() the new code should work anyway.
7538 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * Splitted core library. Core library (lib/silccore) includes
7541 now only SILC protocol specific core (and common) components.
7542 Created new utility library (lib/silcutil) that includes more
7543 generic purpose stuff. The stuff for util library was taken
7544 from the old core library. This was minor and easy split.
7546 * Created SILC Client Library (lib/silcclient) that includes
7547 implementation of the SILC client without user interface. This
7548 was major move from silc/ directory. The code has been changed
7549 so that it is transparent towards the user interface. The
7550 silc/ directory includes now the same user interface as before
7551 and it uses the new client library. Read lib/silcclient/README.
7552 Basicly, the client library performs everything else related
7553 to SILC except user interface handling. Also, configuration
7554 files are considered to be part of user interface and library
7555 does not handle them.
7557 This change also changed a lot of structures, function naming etc.
7558 Most important change was that SilcClientWindow object was
7559 renamed to SilcClientConnection in the client library. Created
7560 also new file lib/silcclient/ops.h. Also added new files
7561 silc/local_command.[ch] and silc/client_ops.[ch].
7563 All these changes were made to make it easier for user interface
7564 designers to create what ever user interface for the SILC client
7567 It is also expected that the server will be moved to lib
7568 directory as well and SILC Server Library will be created;
7569 sometimes in the future.
7571 * Removed Local commands from lib/silccore/silccommand.h as
7572 they are application specific and new client library does not
7573 handle any of those anymore.
7575 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7576 old client implementation in silc/.
7578 * Added support for callback functions in SILC_LOG_* macros.
7579 Application can now set its own callbacks that will be called
7580 instead of using the default functions that will always print
7581 the debug messages to stderr (or stdout). Also, debugging can
7582 now be disabled by setting silc_debug to FALSE and re-enabled by
7583 setting it to TRUE. Note, that logging will still work even
7584 if debugging is disabled.
7586 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7587 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7588 silc_log_reset_debug_callbacks.
7590 * To enable debugging in silc client one must give now -d
7591 option on command line.
7593 * Changed silc_schedule_init to automatically allocate task queues
7594 if they are not allocated before calling it.
7596 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Added GMP 3.1 into math library.
7600 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7603 a channel in SILC network. The packet is used by servers and
7604 routers to notify other routers that user has left a channel.
7605 This little feature was missing until now. Added the feature
7606 to protocol specification as well.
7608 Added functions: silc_server_send_remove_channel_user and
7609 silc_server_remove_channel_user into server.[ch].
7611 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7612 lib/silccore/silcpacket.h. However, they are not implemented
7615 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Fixed joining to a channel and sending channel messages
7618 between server and router. The channel message sending should
7619 now work inside a cell.
7621 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Fixed the private message sending between server and router.
7624 The private message sending should now work inside a cell.
7626 * Added silc_server_replace_id into server.[ch] to replace
7627 existing ID in the SILC network.
7629 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7630 and silc_idlist_replace_server_id into idlist.[ch] in server.
7632 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Fixed the server to server connections. Server can again now
7635 connect to router. Router to router connections probably does
7638 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Added dynamic protocol registering support. Now protocols can
7641 registered and unregistered on the fly. Patch by cras.
7643 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * Added lib/contrib directory to hold routines that some platforms
7646 don't have but are needed by SILC.
7648 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7649 into lin/contrib to provide getopt() and getopt_long() for
7650 those who don't have it.
7652 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7654 * Added AWAY command to client. When away message is set and
7655 client receives a private message packet the client automatically
7656 replies to the sender with the away message.
7658 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7659 bug seemed to be the cause of recent problems when compiling
7662 * Added version detection support to SKE protocol specification
7663 and added the new changes to the SKE implementation as well.
7664 There were other minor changes in the SKE protocol as well.
7666 Many changes in lib/silcske/silcske.[ch] and in
7667 lib/silcske/payload.[ch].
7669 * Added ^U functionality, clear input line. Patch from cras.
7671 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Mainly small bugfixes on core library. Fixed some debugging
7674 logging and buffer overflow in silclog.c.
7676 * Updated config.sub and config.guess on the distribution tree.
7678 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7680 * Added command lagging support in server. Client may execute
7681 commands now only once in two seconds.
7683 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7685 * Optimized packet reception. MAC computation and checking is now
7686 also more optimized. A lot previously duplicated code is now
7687 used as generic by both client and server.
7689 * Fixed key pair generation in clientutil.c
7691 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7693 * Added into lib/silccore/silcbufutil.[ch] new function;
7694 silc_buffer_realloc.
7696 * Moved generic packet sending/encryption functions to
7697 lib/silccore/silcpacket.[ch] from client and server. Some
7698 rewriting of the functions.
7700 * Moved all generic packet reception/decryption functions to
7701 lib/silccore/silcpacket.[ch] from client and server. The
7702 packet processing is now much cleaner in both client and server.
7703 These were major changes in both client and server.
7705 * Created many common functions in server to do packet sending.
7706 Previously code were duplicated a lot, this has been removed
7709 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Rewrote major parts of the ID cache system. Don't know
7712 whether it is better now or not but at least the API is more
7715 * Major rewrite on ID cache stuff on client because of the ID
7716 cache API changes. Added idlist.c to client.
7718 * Also major rewrite on ID cache stuff on server as well.
7719 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7720 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7721 in hand, instead they are all put into the ID cache system now.
7722 All server_idlist_* routines uses ID cache now instead of
7723 traversing its own lists (those lists does not exist anymore).
7724 SilcIDList though still exists. Also, SilcXXXEntry's are
7727 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7729 * Finally made the SKE implementation compliant to the protocol
7730 specification. All mp integers are now binary encoded as
7731 opposed being HEX encoded.
7733 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7736 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7737 functions: silc_[encode/decode]_pem. Also added function
7738 silc_encode_pem_file to PEM encode with newlines ('\n') for
7741 * SILC public keys are now encoded either PEM or binary. Same
7742 option is for private keys as well. By default private keys
7743 are binary encoded and public keys PEM encoded. Silly HEX
7744 encoding were removed.
7746 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7747 function to create fingerprints.
7749 * Fixed a bug in SHA1; does not change the original data anymore.
7751 * Partly implemented INFO command on client and server side.
7752 Fixed CLEAR command. Changes to SERVER command; show current
7753 server(s) when giving command without arguments. Added
7754 VERSION command to client.
7756 * Added check to server that unregistered connections cannot
7757 execute commands (unless it is specificly allowed).
7759 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7761 * Fixed screen refresh.
7763 * Fixed channel joining bug from client. On some circumstances
7764 client tried to join to a channel it had already joined.
7766 * Added public key verification process into client's protocol.c.
7767 The client now verifies the public key from user and saves
7768 it into ~./silc/serverkeys/ directory.
7770 Added into: clientutil.[ch]: silc_client_verify_server_key.
7772 * Changed SKE protocol's silc_ske_initiator_finish function
7773 to accept callback function that verifies the received public
7774 key. Removed old silc_ske_verify_public_key function.
7776 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7779 silc_pkcs_private_key[_data]_set.
7781 * Made the password and public authentication more cleaner in
7782 server's protocol.c.
7784 * Removed historic and obsolete protocol `channel_auth' from
7785 both client and server.
7787 * Removed wrong way of sending command status messages from
7788 server to client in server's command.c. The old way violated
7789 protocol specification.
7791 Changes to silccore/silccommand.[ch]: removed
7792 silc_command_encode_status_payload -> not needed anymore,
7793 changed silc_command_encode_payload_va to accept extra
7794 argument on variable argument list. The argument type must
7795 now be provided to the function. Also, added new function:
7796 silc_command_encode_reply_payload_va which is same as
7797 normal command_encode_payload_va except command status type
7798 is provided as extra argument.
7800 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7802 * Added ~./silc directory handling. The directory includes the
7803 public and private keys for the client.
7805 Added silc_client_check_silc_dir, silc_client_create_identifier
7806 and silc_client_load_keys.
7808 * Implemented SILC protocol compliant public key. Added public
7809 and private key saving to and loading from files.
7811 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7812 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7813 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7814 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7815 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7817 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7818 silc_pkcs_load_[public/private]_key.
7820 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7822 * Added silc_server_get_route (route.[ch]) to get connection
7823 data for the fastest route for given ID.
7825 * Implemented INVITE command on client and server. The command
7826 were re-defined in the SILC Protocol Specification and the
7827 implementation now complies with the specification.
7829 * Implemented PING command on client and server.
7831 * Implemented NAMES command on client and server. The server side
7832 supports currently only normal server not router server yet.
7833 Some changes to NAMES definition in SILC protocol specification.
7835 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7837 * Implemented LEAVE command on client and server.
7839 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7840 again. This change was made to the protocol as well. Server
7841 should not violate the protocol specification anymore.
7843 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7845 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7846 was tested. SOCKS4 was not but should work anyway.
