1 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added SILC_PROTOCOLVERSION macro to check protocol version
4 of a socket connection. The affected file is
5 lib/silcutil/silcsockconn.h.
7 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Some client implementations quit network by doing first LEAVE
10 and then immediately SIGNOFF (like Bombyx). We now do check
11 after a short time after LEAVE notify and check whether the
12 client is still valid after LEAVE, and if not we remove it from
13 cache. Affected file is lib/silcclient/client_notify.c.
15 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
17 * Merged version 1.1.4 of zlib. Even if it not currently in use,
18 it's good not to have security holes here.
20 * Fixed a negative refcount situtuation for the config context.
21 Affected file is silcd/serverconfig.c.
23 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
25 * ROBOdoc documented lib/silcutil/silcutil.h.
27 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
29 * Optimized even more the SilcPacketContext structure. Now
30 totally saved 16 bytes of memory per context after optimization.
31 Affected files are lib/silccore/silcpacket.[ch].
33 * Made strict checks for valid SILC IDs. Affected file is
34 lib/silccore/silcid.c.
36 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Changed the object argument for silc_cipher_register,
39 silc_hash_register, silc_hmac_register and silc_pkcs_register
40 to const. Affected files are lib/silccrypt/silccipher.[ch],
41 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
43 * Changed the silc_get_username and silc_get_real_name to
44 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
46 * Fixed the Irssi SILC Client to use the silc_get_username and
47 silc_get_real_name insted of glib routines since the glib
48 routines only corrupt stack. Fixes the Irssi SILC to work in
49 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
51 * Fixed the Irssi to not use g_get_home_dir since it crashes
52 or returns garbage on cygwin and corrupts stack. Added function
53 get_home_dir to Irssi routines. Affected files are
54 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
56 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
58 * Made some structure optimizations. SFTP memory FS MemFSEntry
59 entry structure. Optimized SilcTask structure. Optimized
60 SilcPacketContext structure.
62 Affected files lib/silcsftp/sftp_fs_memory.c,
63 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
65 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
67 * And yet again reverted back the config thing since Johnny
68 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
71 * Fixed memory leaks from config object. Affected files are
72 silcd/serverconfig.[ch].
74 * Added support for adding new connections to the server in rehash.
75 After rehash they take effect.
77 Added support for changing the maximum allowed connections in
78 rehash. The number can grow but going smaller is not supported.
80 Added function silc_server_num_sockets_by_remote to the
81 silcd/server_util.[ch].
83 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
85 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
87 * Added preliminary checking during config parsing for a valid
88 public/private key and removed further checks in the code.
89 Affected files are silcd/serverconfig.[ch], server.c.
91 * Moved functions silc_server_drop() and silc_server_daemonise()
92 from server.c to silcd.c since they are stricly related to
93 the application activity.
95 * Reverted a small part of the automatic ref/unref since
96 it caused a double unref in some situations. Affected
97 files are silcd/silcd.[ch], server.c, serverconfig.c.
99 * Added some .cvsignore files in the lib directory.
101 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
103 * Fixed silc_net_gethostbyaddr to correctly resolve by
104 address. Affected file lib/silcutil/silcnet.c.
106 * Fixed the notify relaying to client. The HMAC to be used
107 with relayed packets ws wrong and caused decryption failure
108 at the client end. Affected file is silcd/packet_receive.c.
110 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
112 * Created new branch silc_protocol_1_0_branch.
114 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
116 * Changed the silc_server_config_* routines to be SilcServer
117 independent. They are now officially application specific code
118 and not part of generic server implementation. Affected files
119 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
121 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
123 * Added automatic referencing of config context in the
124 silc_server_config_alloc, and automatic unreferencing in the
125 silc_server_config_destroy. Affected files are
126 silcd/serverconfig.[ch], silcd/silcd.c.
128 * Fixed the silc_log_quick handling in the logging routines.
129 It didn't log quickly when it was TRUE. Affected file is
130 lib/silcutil/silclog.c. Also the flush delay was set even
131 if it was 0 in config file. Affected file is
132 silcd/serverconfig.c.
134 * Added support for changing key pair of the server in rehash.
135 Affected file silcd/server.c.
137 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
139 * Fixed the TOPIC_SET notify to not cras. It changed the topic
140 too early, before getting the channel entry. Affected file
141 is silcd/packet_receive.c.
143 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
145 * Added functions silc_server_config_[ref/unref], these are used
146 to prevent that the config object is destroyed.
148 No longer directly affect global variables silc_log_quick and
149 silc_log_delay, they are first cached inside the config object
150 and then applied with silc_server_config_setlogfiles().
152 silc_server_config_set_defaults() is now internal to
153 serverconfig.c, there are no reasons to show this internal stuff
156 Affected files are silcd/serverconfig.[ch].
158 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
159 fprintf's to stderr, since some code may be executed again after
160 the server went into the background. Affected files are
163 * Added rehash support. Added function silc_server_rehash() that
164 will perform all the basic tasks of the rehashing procedure.
166 * Added command line option `-x, --hexdump'. This will enable the
167 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
168 The option `--hexdump' implies `--debug'.
170 * Fixed a bad bug in the logging APIs (silcutil library) where
171 the application would crash after calling silc_log_reset_all().
173 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Fixed the KICKED notify handling in client library to
176 correctly remove the channel and all entries from the
177 channel when I was kicked. This bug crashed the client.
179 Fixed yet another but in KICKED notify handling to remove
180 the kicked client correctly from the channel.
182 Affected file is lib/silcclient/client_notify.c.
184 * Fixed a minor bug in looking up correct client entry
185 in KICKED notify in server. Affected file is
186 silcd/packet_receive.c.
188 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
189 sources correctly to distribution. Fixes --with-gmp option.
191 * Removed the manual rehashing from ID Cache, and changed it
192 to use the SILC Hash Table's auto rehash feature. Affected
193 file is lib/silccore/silcidcache.c.
195 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed a bug in the silc_client_nickname_format function that
198 handles the multiple same nickname formatting. Two clients
199 with same nickname caused problems after the first one left
200 and rejoined. It didn't format the nickname correctly.
201 Affected file is lib/silcclient/idlist.c.
203 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
205 * Don't change the topic if olod topic is same as new one.
206 Affected file is silcd/packet_receive.c.
208 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
210 * Added cross-reference support to the SILC Documentation
211 generator. All types across all HTML files are now cross-
212 referenced. Affected files util/robodoc/generator.c and
213 scripts/silcdoc/silcdoc.
215 * Added file lib/silcutil/silctypes.h to include all the
216 arithmetic type definitions and some macros. Removed
217 includes/bitmove.h and moved macros to silctypes.h.
219 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
221 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
223 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
225 * Added `type' argument to silc_id_payload_parse_id function which
226 now returns the type of the ID to the sent pointer. Affected
227 file is lib/silccore/silcid.[ch].
229 * Added check for CMODE_CHANGE notify type that mode change is
230 allowed by the sender. Affected file silcd/packet_receive.c.
232 * Added check for CUMODE_CHANGE notify type that mode change is
233 allowed by the sender. Affected file silcd/packet_receive.c.
234 Added the ID type as CUMODE_CHANGE notify type as argument
235 to the `notify' client operation. Affected files are
236 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
238 * Added function silc_client_add_server to the client library.
239 Added support for resolving also channel and server info when
240 received unknown entity in notify packet. Affected files are
241 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
243 * Added function silc_command_get_status to return the command
244 status from the command reply's argument payload. Affected files
245 are lib/silccore/silccommand.[ch].
247 * Added check for KICKED notify type that the kicking is
248 allowed by the client. Affected file silcd/packet_receive.c.
250 * Created function silc_get_input which can be used to get input
251 (echo on or off) from user on command line. Affected files are
252 lib/silcutil/silcutil.[ch].
254 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
256 * Optimized silc_server_packet_relay_to_channel function.
257 Added new function silc_channel_message_payload_encrypt which
258 can be called directly if channel message payload needs to
259 be encrypted and is already encoded (no need to call _encode
260 function). Packet relaying is now done by router without any
261 extra memory allocations. Affected files are
262 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
265 * Fixed the INVITE notify handling. It took wrong arguments
266 as invite list and invite delete. Affected file is
267 silcd/packet_receive.c.
269 * Added check for TOPIC_SET notify type that the topic change is
270 allowed by the client. Affected file silcd/packet_receive.c.
272 * Added check for INVITE notify type that inviting is allowed by
273 the client. Affected file silcd/packet_receive.c.
275 * Changed the silc_server_client_on_channel to return the
276 SilcChannelClientEntry as well. Moved the function
277 silc_server_check_cmode_rights to server_util.[ch].
278 Affected files are silcd/server_util.[ch], silcd/command.c.
280 * Added function silc_server_check_umode_rights to check whether
281 changing client's user mode is allowed. Added check for
282 UMODE_CHANGE notify type that the umode change is allowed
283 by the client. Affected files are silcd/server_util.[ch],
284 silcd/packet_receive.c and silcd/command.c.
286 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
288 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
289 ID length. It ignored that ID can be IPv6 based as well.
290 Affected file lib/silccore/silcpacket.h.
292 * Fixed the silc_id_id2str and silc_id_str2id to take the
293 IPv6 address offset's into consideration. Affecte file is
294 lib/silccore/silcid.c.
296 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Fixed the internal Unix scheduler functions to check for
299 NULL context they may receive. The affected file is
300 lib/silcutil/unix/silcunixschedule.c.
302 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
304 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
305 can specify different directory with --home command line
306 parameter. Affected files irssi/src/silc/core/client_ops.c,
309 * SILC-specific commands aren't now executed if the active server
310 isn't of SILC-type, so there won't be problems with having
311 IRC and SILC protocol support in same client. Affected files
312 irssi/src/silc/core/silc-channels.c, silc-servers.c,
315 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Improved the signal support in SILC Schedule. Added new
318 function silc_schedule_signal_call which is used by application
319 to mark a signal to be called. It is now safe to perform
320 any kind of tasks in signal callbacks since it is guaranteed
321 that the application specified signal callback is called
322 after the signal is over. Affected files are
323 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
325 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
327 * Added `name' field to SilcChannelPrivateKey to represent
328 application given name for the key. Moved also the context from
329 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
330 Added the `name' argument also to the function
331 silc_client_add_channel_private_key.
333 Added function silc_client_current_channel_private_key to set the
334 current channel private key in use.
336 Added "change" command to KEY command which can be used to change
337 the current channel private key. Bound the command also to
340 Also affected files lib/silcclient/client_channel.c,
341 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
343 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
345 * Added silc_rng_get_byte_fast function in to the
346 lib/silccrypt/silcrng.[ch].
348 * Changed the interface of silc_packet_assemble and the
349 silc_packet_send_prepare. If silc_packet_assmble is now
350 called the application does not call silc_packet_send_prepare
351 because the library will call it automatically. These
352 interfaces now also return a reference to the outgoing buffer
353 which includes the assembled packet, which the application can
354 use to encrypt the packet.
356 Affected files are lib/silccore/silcpacket.[ch],
357 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
358 silcd/packet_send.c, server_backup.c and packet_receive.c.
360 * Fixed a packet sending bug on very high load, where outgoing
361 packet queue wasn't handled correctly and packets got corrupted.
362 Affected files are lib/silcutil/*/silc*sockconn.c,
363 lib/silcclient/client.c and silcd/server.c.
365 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
367 * Added macro SILC_PACKET_DATALEN which can be used during
368 packet assembling to check whether the data to be added to
369 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
370 len is truncated until it fits it.
372 Added checks for maximum length of channel message payload and
373 private message payload also.
375 Added checks for maximum packet length in server and in
378 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
379 lib/silcclient/client.c, lib/silccore/silcchannel.c and
380 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
381 lib/silcclient/client_prvmsg.c.
383 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
385 * Added silc_server_packet_queue_purge call to the
386 silc_server_disconnect_remote to assure that all data in the
387 queue before disconnecting is sent to the network. Affected
390 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Added the deleting of server's own ID cache entry to the
393 silc_server_free function. Free also everything else that
394 has been allocated in silc_server_init. The affected file
397 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
399 * Added functions silc_parse_version_string, silc_version_to_num,
400 and silc_ske_parse_version to parse SILC protocol style version
401 strings. Affected files lib/silcutil/silcutil.[ch] and
402 lib/silcske/silcske.[ch].
404 * Added new configuration params: version_protocol, version_software
405 and version_software_vendor to specify what version the remote
406 host must at least be to be able to connect to server. The vendor
407 string can be regex matched too. Added new function
408 silc_server_connection_allowed to check maximum number of allowed
409 connections, and allowed versions for incoming connections.
410 Affected files are silcd/server.c, server_util.[ch] and
413 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Added preliminary support for signals in scheduler. The
416 signals we care about are now blocked always when the scheduler
417 is locked. This way we can synchronise the use of signal with
418 scheduler. It is guaranteed that when signal occurs the scheduler
419 is not locked, and thus new tasks can be safely added to the
422 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
423 to silc_schedule_internal_init and silc_schedule_internal_uninit.
424 Added new platform specific routines
425 silc_schedule_internal_signals_[un]block and
426 silc_schedule_internal_signal_[un]register.
428 Added new functions to SILC Schedule API:
429 silc_schedule_signal_[un]register. Each signal that application
430 is going to use should be registered to the scheduler.
432 Affected files are lib/silcutil/silcschedule.[ch],
433 lib/silcutil/*/silc*schedule.c.
435 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
437 * Check for unauthenticated client and server in the
438 silc_server_new_client and silc_server_new_server functions.
439 Affected file silcd/packet_receive.c.
441 * Added function silc_string_is_ascii to check whether given
442 string is 7-bit ASCII string. Affected files are
443 lib/silcutil/silcutil.[ch].
445 * Added function silc_id_is_valid_server_id into the
446 silcd/serverid.c and added checking for valid Server ID's in
447 silc_server_new_server. The Server ID must always be based
448 on the server's public IP address.
450 * Added logging of DISCONNECT packet message in the server.
451 Affected file silcd/server.c.
453 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Changed all library interfaces that use Global RNG to also
456 accept SilcRng as argument. Affected files are
457 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
458 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
459 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
460 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
463 * Added function silc_pkcs_generate_key to the
464 lib/silccrypt/silcpkcs.[ch] for applications so that they
465 don't need to do pkcs->pkcs->init calls anymore.
467 * Remove SilcSocketConnection from the SFTP API since it really
468 wasn't needed there. The application has the information
469 saved in its contexts anyway and the SFTP layer doesn't need
470 know about it. Affected files lib/silcsft/silcsftp.h and
471 lib/silcsftp/sftp_[server/client].c.
473 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
474 The SilcSimContext is not SilcSim.
476 * Fixed possible buffer overflows in silc_id_render in the
477 lib/silcutil/silcutil.c.
479 * On EPOC the global crypto module lists are not used at all
480 in the crypto library. Added support for using the constant
481 algorithm list on EPOC. Affected files are
482 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
485 * Fixed the handling of third parameter of KICKED notify, since
486 it was mistakenly updated to SILC Protocol 1.0 even though it
487 is to be included in 1.1. Since it is not in 1.0 it is not
488 mandatory, and this fix now handles it only if it is provided,
489 and it is not error if it is not provided. Affected file
490 lib/silcclient/client_notify.c.
492 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
494 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
495 client. Affected file irssi/src/silc/core/client_ops.c.
497 * Merged with Irssi 0.8.4 from irssi.org CVS.
499 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
501 * Check for valid socket connection in client entries before
502 sending any messages. Fixes a crash, but doesn't fix some
503 other underlaying bug that is lurking there. Affected
504 file silcd/packet_send.c.
506 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
508 * $usermode, $cumode and $cumode_space expandos shouldn't do
509 anything with non-SILC server records. Affected file
510 irssi/src/silc/core/silc-expandos.c
512 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
514 * Fixed the silc_net_check_[host/local]_by_sock to support
515 IPv6 bound sockets as well. Now they can return IPv6 addresses
516 as well. Affected file lib/silcutil/silcnet.c.
518 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
519 Affected lib/silcutil/unix/silcunixnet.c.
521 * Fixed ID rendering (at least on some platforms, not NetBSD)
522 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
524 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Added silc_hash_public_key and silc_hash_public_key_compare
527 functions to be used with SilcHashTable. They can be used to
528 hash public keys and compare public keys in hash table. Affected
529 file lib/silcutil/silcutil.[ch].
531 * Added support for specifying multiple public keys for Client
532 connection section in server configuration file. This makes it
533 possible to accept multiple public keys from same host, or to
534 make a section that accepts any incoming host, and have the
535 accepted public keys listed in the section.
537 Added functions silc_sever_[find/get]_public_key, added the
538 support for this actually to all connection sections but only
539 the Client section is currently allowed to specify multiple

692 * Added `user_count' to the SilcChannelEntry which now tells the
693 number of users on the channel. The user count is now saved
694 in normal server of global channels as well. Affected files
695 silcd/server.c, idlist.h, packet_receive.c and command.c.
697 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

709 Affected file lib/silcclient/client.c.
711 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * ROBOdoc documented the lib/silcske/silcske.h, and improved
714 the SKE interface a bit.
716 * Fixed padding problem in PKCS#1. The padding was not actually
717 random since the random number generator was used incorrectly.
718 This security bug affects only when encrypting with PKCS#1, and
719 it is not currently used at all in SILC. SILC only use signing
720 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
722 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

796 whether given configuration value has been given already.
798 Affected files silcd/serverconfig.[c], server.[c].
800 * Splitted the doc/example_silcd.conf.in. Separated the crypto
801 algorithm parts and created new file silcalgs.conf, that
802 is now included from the example_silcd.conf.in.
804 * Optimized the silc_server_connect_to_router_second to take
805 the connection configuration object from the SilcServerConnection
806 object instead of finding it during the connecting phase.
807 Added the configuration object to SilcServerConnection struct.
808 Affected files silcd/server_internal.h, server.c.
810 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

892 * Fixed the file transfer's key agreement payload to include
893 zero port also if the hostname is NULL because it could not
896 Call file transfer monitor callback now also if error occurs
897 during key agreement protocol.
899 Changed the silc_client_file_send interface to return the
900 SilcClientFileError instead of session id. The session ID
901 is returned into pointer provided as argument.

918 file lib/silcutil/silclog.c.
920 * Fixed the channel message payload decryption in the function
921 silc_channel_message_payload_decrypt to not modify the original
922 buffer before it is verified that the message decrypted
923 correctly. Otherwise, next time it is called with correct
924 channel key it won't encrypt since the payload is corrupted.
925 Affected file lib/silccore/silcchannel.c.
927 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

970 users list to SilcHashTable. The affected files are
971 lib/silcclient/idlist.[ch].
973 * Fixed a bug in hash table tarversing. While the hash table
974 is traversed with SilcHashTableList the table must not be
975 rehashed. It is now guaranteed that auto rehashable tables
976 are not rehashed while tarversing the list. Also defined that
977 silc_hash_table_rehash must not be called while tarversing
978 the table. Added function silc_hash_table_list_reset that must
979 be called after the tarversing is over. The affected files are
980 lib/silcutil/silchashtable.[ch].
982 * Changed all hash table traversing to call the new
983 silc_hash_table_list_reset in server and in client library.
985 * Added function silc_client_on_channel to return the
986 SilcChannelUser entry if the specified client entry is joined
987 on the specified channel. This is exported to application as
988 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

997 lists correctly. Affected file silcd/command.c.
999 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1001 * When sending JOIN command to router for processing the
1002 sender's old command identifier was not saved back to the
1003 sender's command context, fixed now. The affected file is
1006 * Create the key in JOIN command of the router did not return
1007 the channel key, added check for this. Affected file is
1010 * Fixed a channel ID update bug in JOIN command reply. Do
1011 not directly upgrade the ID but call the function
1012 silc_idlist_replace_channel_id if the ID was changed.
1013 Affected file silcd/command_reply.c.
1015 * Fixed memory leaks from command calling if it would fail.
1016 Affected file silcd/command.c.

1043 functions. Affected file silcd/server.c.
1045 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1046 which ID was changed. This way the router will send the
1047 user list for the channel again, and server won't be in
1048 desync in some rare circumstances. Affected file is
1049 silcd/packet_receive.c.
1051 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1077 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1079 * Added server & router operator statistics updating. Affected
1080 file silcd/packet_receive.c and silcd/command.c.
1082 * Fixed the SERVER_SIGNOFF notify handling on normal server
1083 not to save the history information for clients. Same was
1084 fixed earlier in remove_clients_by_server function, but not
1085 here. Affected file silcd/packet_receive.c.
1087 * Raised the default connection-retry count from 4 to 7 in
1088 server. Affected file silcd/server.h.
1090 * Cancel any possible reconnect timeouts when we start the
1091 key exchange. Affected file silcd/server.c.
1093 * Do not reconnect on connection failure when SCONNECT was
1094 given. Affected files silcd/server.[ch].
1096 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1100 * Fixed the NICK command to always give the unformatted
1101 nickname to the one giving the NICK command. If unformatted
1102 nickname is cached already it will be formatted and the
1103 local entry will always get the unformatted nickname.
1104 Affected file lib/silcclient/idlist.c.
1106 * Fixed some double frees from client library commands.
1107 Affected file is lib/silcclient/command.c.
1109 * Fixed CUMODE command in server to assure that no one can
1110 change founder's mode than the founder itself, there was a
1111 little bug. Affected file silcd/command.c.
1113 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1115 * Removed the SilcClientCommandDestructor from the client
1116 libary, it is not needed anymore. Affected files are
1117 lib/silcclient/silcapi.h, command[_reply].[ch],
1118 client_notify, idlist.c.
1120 * Fixed GETKEY command to first resolve client, and then
1121 resolve the server only if the client was not found, instead
1122 of resolving both at the same time. Affected file is
1123 lib/silcclient/command.c.
1125 * Added silc_client_start_key_exchange_cb and lookup the
1126 remote hostname and IP address before starting the key
1127 exchange with server. The affected file is
1128 lib/silcclient/client.c.
1130 * The server's public key is now saved using the IP address
1131 of the server and not the servername for the filename.
1132 The hostname public key filename is checked as an fall back
1133 method if the IP address based filename is not found.
1135 Fixed the GETKEY command to save the fetched server key
1136 in correct filename.
1138 Print the remote server's hostname now when new key is
1139 received during connection process. Affected file is
1140 irssi/src/silc/core/client_ops.c.
1142 * Return always our own public key to the client if it asks
1143 for it with GETKEY command. Affected file silcd/command.c.
1145 * Removed the use_auto_addr variable from default config
1146 file since it was in wrong section. Affected file is
1149 * Fixed TOPIC_CHANGE notification to not route it when it
1150 was sent using silc_server_send_notify_to_channel function.
1151 Affected file silcd/command.c.
1153 * Fixed silc_server_send_notify_kicked to send the kicker's
1154 Client ID also, it was missing. Affected files are
1155 silcd/command.c, silcd/packet_send.[ch].
1157 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1159 * Do not save client history information in SERVER_SIGNOFF.
1160 Fixes the bug in normal server that it does not detect
1161 the client becoming valid after the server becomes back
1162 online. Affected file silcd/server_util.c.
1164 * Added `sock_error' field into the SilcSocketConnection
1165 context. When error occurs during socket operation (read
1166 or write) the error is saved. Added also new function
1167 silc_socket_get_error to return human readable socket error
1168 message. Affected files are lib/silcutil/silcsockconn.[ch],
1169 lib/silcutil/unix/silcunixsockconn.c, and
1170 lib/silcutil/win32/silcwin32sockconn.c.
1172 * The server now prints the socket error message in the
1173 signoff for client. Affected file silcd/server.c.
1175 * Fixed the `created' channel information sending from router
1176 to server in JOIN command. Checks now whether the channel
1177 really was created or not and set it according that.
1179 Fixed the JOIN command to use the client entry's current
1180 ID during the joining procedure instead of the one it sent
1181 in the command (it is checked though), since it can change
1182 between the packet processing and command processing, and
1183 would just case unnecessary pain in the client end. Affected
1184 file silcd/command.c.
1186 * Fixed a channel key payload sending to use correct channel
1187 ID when the server was forced to change the channel's ID by
1188 router. Router sent the key payload with the old Channel ID.
1189 Affected file silcd/packet_receive.c.
1191 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1193 * Call silc_server_save_channel_key only if the key payload
1194 was provided in the JOIN command's command reply. Affected
1195 file silcd/command_reply.c.
1197 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1199 * Fixed silc_mp_sizeinbase to return the value correctly with
1200 MPI. Affected file lib/silcmath/mp_mpi.c.
1202 * Fixed the stop_server signal to correctly stop the scheduler
1203 and gracefully stop the server when SIGTERM or SIGINT signals
1204 are received. Affected file silcd/silcd.c.
1206 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1208 * Simple handling of TERM and HUP signals. Also added some log
1209 flushing call around. Affected file is
1212 * Fixed small bugs in silclog.c. Now buffering output will take
1213 effect after 10 seconds since startup: This will ensure that
1214 no important startup messages are lost. Also output redirection
1215 will preserve original format ([Date] [Type] message).
1216 Affected file is lib/silcutil/silclog.c.
1218 * Added two options to the config file, in the logging section:
1219 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1220 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1222 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1224 * Do not print the warning about log files not being initialized
1225 more than once to avoid excess logging. Affected file is
1226 lib/silcutil/silclog.c.
1228 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1229 the SIM copying in make install in Makefile.am.pre.
1231 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1233 * Rewritten silclog APIs. Globally interesting changes follows:
1234 silc_log_set_files() changed to silc_log_set_file().
1235 silc_log_set_callbacks() changed to silc_log_set_callback().
1236 ROBOdoc documented silclog header file.
1237 SilcLogCb now returns bool to wether inihibit the default
1238 handler or not (to keep the old behaviour return always TRUE).
1239 The new APIs should also fix the problem of the
1240 silcd_error.log file that was written in the current directory.
1243 Log files streams will remain opened after silc_log_set_file()
1244 call, means less CPU usage notably on high traffic servers.
1245 File streams are now full buffered, and flushed to the disk
1246 every 5 minutes, lesses HD activity and CPU usage.
1247 Messages can be redirected, allowing admins to configure
1248 one single logfile for all server messages.
1249 the silc_log_quick global variable to activate fast-logging.
1250 Affected files lib/silcutil/silclog.[ch]
1252 * Changed some code to conform new silclog APIs. Affected
1253 files are doc/example_silcd.conf.in, silcd/server.c
1254 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1257 * Fixed a memory leak that could occur in some situations.
1258 Affected file silcd/serverconfig.c.
1260 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1262 * Added the silc_client_del_client to remove the client from
1263 all channels as well. Affected file lib/silcclient/idlist.c.
1265 * Fixed the client library to correctly remove the client
1266 from all channels when the client entry is being destroyed.
1267 Affected file lib/silcclient/client_notify.c, command.c.
1269 * Added auto-nicking support to the client library. If the
1270 applicatio now sets client->nickname it will be sent to the
1271 server after connecting by the library. This way for example
1272 SILCNICK (or IRCNICK) environment variables will have effect
1273 and always change the nickname automatically to whatever
1274 it is wanted. Affected file lib/silcclient/client.[ch].
1276 * Renamed silc_server_command_bad_chars to the
1277 silc_server_name_bad_chars and moved it to the
1278 silcd/server_util.[ch]. Added also new function
1279 silc_server_name_modify_bad to return nickname that
1280 includes bad characters as new nickname without those
1281 bad characters. This check and modify is now used in
1282 silc_server_new_client when the username is initially set
1283 as nickname, so it must be checked to be valid nickname.
1284 Affected file silcd/packet_receive.c.
1286 * The nickname length is now taken from the packet for real
1287 and not trusted to strlen() since it clearly can return
1288 wrong length for nickname including bad characters. This
1289 also applies to channel names. Affected file silcd/command.c.
1291 * Removed the lib/silcsilm/modules directory. Modules are now
1292 compiled into the lib/silcsim. Fixed the copying of the
1293 modules to follow symbolic links in Makefile.am.pre.
1295 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1297 * Fixed silc_string_regexify list creation. Fixes bugs with
1298 BAN and INVITE commands in server. The affected file is
1299 lib/silcutil/unix/silcunixutil.c.
1301 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * Removed the command destructor entirely from the server's
1304 command and command reply routines. It is not needed, and
1305 its usage was buggy and caused crashes. Affected files are
1306 silcd/command[_reply].[ch].
1308 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Cancel protocol and NULL sock->protocol if timeout
1311 occurred during protocol. Affected file silcd/server.c.
1313 * Cancel protocol timeouts always before calling the final
1314 callback, to assure that after final callback is called
1315 no other state will be called for the protocol anymore.
1316 Affected file silcd/protocol.c.
1318 * Print error log if incoming connection configuration could
1319 not be found. Affected file silcd/server.c.
1321 * Fixed JOIN command to correctly save the founder mode
1322 to the client on normal SILC server, when the channel
1323 was created by the router. Affected file silcd/command.c.
1325 * Fixed LIST command (hopefully) to send correct reply
1326 packets. Affected file silcd/command.c.
1328 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * The silc_packet_receive_process now returns FALSE if the
1331 read data was invalid packet, and TRUE if it was ok.
1333 The server now checks that if unauthenticated connection
1334 sends data and its processing fails the server will close
1335 the connection since it could be a malicious flooder.
1337 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1339 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1341 * Make sure the warning about error opening a log file is
1342 printed only once and not everytime it fails (produces
1343 too much useless log). Affected file lib/silcutil/silclog.c.
1345 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1347 * Made the silc_server_daemonise() function more readable.
1348 Affected file silcd/server.c.
1350 * Pid file is now optional, the user may comment it out from
1351 the config file. Removed define SILC_SERVER_PID_FILE, we
1352 don't need a default any longer. Affected file
1353 configure.in.pre, lib/Makefile.am.pre.
1355 * Make some use of the pid file. The server now dies at startup
1356 if it detects a valid pid file on his path. The server would
1357 die anyway in this circumstance, because of the bind() failure.
1358 Affected file silcd/silcd.c.
1360 * No longer compiling lib/dotconf.
1362 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Fixed JOIN command parsing not to crash. Affected file
1365 lib/silcclient/command.c.
1367 * Fied the NICK_CHANGE notify to add the new client entry
1368 even it is resolved. This removes an <[unknown]> nick
1369 thingy bug in the client. Affected file is
1370 lib/silcclient/client_notify.c.
1372 * Do not try to allocate 0 bytes (efence does not like it)
1373 in lib/silccore/silccomand.c when encoding payload.
1375 * Do not take IRCNICK as nickname in Irssi SILC client since
1376 it is not possible to set nickname before hand connecting
1377 the server (TODO has an entry about adding auto-nicking
1380 * Changed the silc_server_command_pending to check whether
1381 there already exists an pending entry with the specified
1382 command, command identifier and pending callback. This is
1383 to fix IDENTIFY and WHOIS related crashes that may register
1384 multiple pending commands with same identifier. Affected
1385 file silcd/command.c.
1387 * Fixed the server to reconnect to the router even if it
1388 was already reconnecting and EOF was received. This to
1389 fix a possibility that the server wouldn't ever try to
1390 auto-reconnect to the router. Affected file silcd/server.c.
1392 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1394 * Fixed the server's password authentication to use the
1395 length of the locally saved password, and not the one
1396 sent in the packet. Affected file silcd/protocol.c.
1398 * Fixed same password authentication problem in the
1399 Authentication Payload handling routines in
1400 lib/silccore/silcauth.c.
1402 * Yet another password authentication problem fixed with
1403 channel password handling in silcd/command.c.
1405 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * If first character of string in silc_parse_userfqdn is '@'
1408 then do not parse it. Affected file is
1409 lib/silcutil/silcutil.c.
1411 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Fixed minor bug in IDENTIFY command reply sending, which
1414 caused various weird problems during JOIN when it was
1415 resolving names for users. Affected file silcd/command.c.
1417 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Fixed the IDENTIFY command reply sending to chech better valid
1420 clients. It was possible to send incomplete list of replies.
1421 Affected file silcd/command.c.
1423 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Added silc_client_command[s]_[un]register functions now to
1426 dynamically register the commands in client library. Removed
1427 the static table of commands. This allows the client library
1428 to call commands without causing the application to know about
1429 what commands library has called.
1431 Removed the INFO command reply kludge to detect when the command
1432 was called by library. Now library use its own command reply
1433 function for INFO command.
1435 Added function silc_client_command_call to call a command.
1436 Application can use it to call command, not access the structure
1439 Now all commands that are sent by the client library (not
1440 explicitly sent by application) use own command reply functions.
1442 Affected files around lib/silcclient/ and in
1443 irssi/src/silc/core/.
1445 * Fixed the WHOIS command reply sending to chech better valid
1446 clients. It was possible to send incomplete list of replies.
1448 Fixed the WHOIS and IDENTIFY to send the request to router
1449 if normal server did not do it and did not find any results.
1451 Affected file silcd/command.c.
1453 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1455 * Moved the internal data from SilcClient context into its
1456 own file, not accesible to application. Affected files
1457 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1458 and other files in client library.
1460 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Added doc/examples installation target in Makefile.am.pre.
1465 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1468 commands the found client entry will be removed from the
1469 cache, after notifying application about the error. Affected
1470 file lib/silcclient/command_reply.c.
1472 * Changed the /MSG to check for exact nickname user gave, and
1473 not let `nick' match `nick@host' if it is only one found. Now,
1474 user must type the exact nickname (like nick@host2) even if
1475 there are no more than one same nicks found. This is to avoid
1476 a possibility of sending nickname to wrong nickname since
1477 `nick' could match `nick@host'. Affected file is
1478 irssi/src/core/silc-servers.c.
1480 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Do not print "you are now server operator" or similar when
1483 giving /away command. Affected files are
1484 irssi/src/silc/core/client_ops.c, silc-servers.h.
1486 * Made the silc_server_command_pending_error_check to send
1487 the same command reply payload it received back to the
1488 original sender of the command. This way all arguments
1489 that was received by the server will be received by the
1490 client too. Affected file silcd/command.c.
1492 * Added the silc_idcache_add to return the created cache entry
1493 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1495 * Add global clients to expire if they are not on any channel.
1496 This is because normal server will never know if they signoff
1497 if they are not on any channel. The cache expiry will take
1498 case of these entries. This is done by normal servers only.
1499 The affected files are silcd/command_reply.c,
1500 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1502 * If server receives invalid ID notification for WHOIS or
1503 IDENTIFY and the ID exists in the lists, it is removed.
1504 Affected file silcd/command_reply.c.
1506 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1507 in client then client entry that it matches is searched and
1508 the nickname is printed on the screen for user. Affected
1509 file irssi/src/silc/core/client_ops.c.
1511 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Use cache entry expire time in the LIST command reply to
1514 purge old entries from the cache after the LIST command
1515 reply has been received. This way we don't have non-existent
1516 entries in the cache for too long. Affected file is
1517 silcd/command_reply.c.
1519 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * If we are normal server, and we've not resolved client info
1522 in WHOIS or IDENTIFY from router, and it is global client,
1523 we'll check whether it is on some channel. If it is not
1524 then we cannot be sure about its validity and will resolve it
1525 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1526 file silcd/command.c.
1528 * Search channel by name (if possible) rather than by ID
1529 in IDENTIFY command's command reply. Affected file is
1530 silcd/command_reply.c.
1532 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1534 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1535 Updated specs and implemented it. Affected file silcd/command.c,
1536 silcd/packet_send.c and silcd/packet_receive.c.
1538 * Implemented the <founder auth> payload handling in the JOIN
1539 command. If provided all conditions for channel joining
1540 except requirement to provide correct passphrase can be
1541 overrided by the channel founder. Updated the protocol specs.
1542 Affected file silcd/command.c.
1544 Added support for founder auth in JOIN command in client
1545 library. Fixed the parsing of the JOIN command now to support
1546 all options as they should be. The affected file is
1547 lib/silcclient/command.c.
1549 * Optimized the WHOIS and IDENTIFY commands to send the request
1550 to router only if it includes nicknames or other names. If
1551 they include only IDs then check the local cache first before
1552 routing. Affected file is silcd/command.c.
1554 * Added channels topic announcements. Affected file is
1555 silcd/packet_receive.c and silcd/server.c.
1557 * Fixed the silc_server_send_notify_topic_set to really destine
1558 the packet to channel. Affected file silcd/packet_send.c.
1560 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1561 library. Affected file lib/silcclient/client_notify.c.
1563 * Added UMODE announcements. Affected file silcd/server.c.
1565 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Memory leak fixes in:
1569 lib/silcutil/silcsockconn.c
1570 lib/silcske/silcske.c
1571 lib/silcske/groups.c
1573 lib/silccrypt/silcpkcs.c
1574 lib/silccore/silccommand.c
1575 lib/silccore/silcidcache.c
1580 * ROBOdoc documented the lib/silcske/groups.h file and a
1581 bit changed the interface for better.
1583 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1585 * Update the client entry context in the ID cache after
1586 nick change. Affected file lib/silcclient/command.c.
1587 Fixes the CUMODE command when regaining founder privileges,
1588 and a little WHOIS problem.
1590 * Fixed silc_net_gethostbyname to correctly call the
1591 inet_ntop. Affected file lib/silcutil/silcnet.c.
1593 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1595 * Added IPv6 support checking to the configure.in.pre, added
1596 also --enable-ipv6 option to override the check. Affected
1597 file configure.in.pre.
1599 * The silc_thread_create now calls the start function
1600 directly if threads support is not compiled in. Removes
1601 ugly #ifdef's from generic code. Affected files are
1602 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.

1616 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1617 routines. Added silc_net_is_ip[4/6]. Affected file is
1618 lib/silcutil/unix/silcunixnet.c. All routines that take
1619 address as argument now supports both IPv4 and IPv6 addresses.
1621 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1623 * Fixed LIST command reply sending in server. Affected file
1626 * Server now sends the kicker's client ID in the KICK notify
1627 to the kicked client. Affected file silcd/command.c.
1629 * The client library now parses the kickers client ID and
1630 UI displays it. Affected files lib/silcclient/client_notify.c
1631 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1633 * Made all payload parsing function prototypes consistent.
1634 They all take now const unsigned char * and uint32 pair as
1635 the payload data instead of SilcBuffer. Changes all around
1636 the source tree. Other unsigned char* -> const unsigned char*
1637 changes around the tree as well.
1639 * Optimized SFTP client and server packet sending not to
1640 allocate new buffer for each packet but to recycle the
1641 first allocated buffer. Affected files are
1642 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1644 * Optimized the SFTP client to use SilcList instead of
1645 SilcDList for requests, because it is faster. Affected file
1646 is lib/silcsftp/sftp_client.c.
1648 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1649 into lib/silccore/silcid.[ch].
1651 Renamed silcpayload.[ch] into silcargument.[ch].
1653 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * If client entry is deleted with active key agreement
1656 session, abort the session.
1658 The silc_client_abort_key_agreement now calls the completion
1659 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1661 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1664 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * Don't use __restrict in older GCC's. Affected file is
1667 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1669 * silc_net_localhost now attempts to reverse lookup the
1670 IP/hostname. Affected file lib/silcutil/silcnet.c.
1672 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1673 command. It can be used to gain founder privileges at
1674 the same time when joining the channel.
1676 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1677 kicker's client ID as well. Updated protocol specs.
1679 Defined that the server must send SILC_COMMAND_IDENTIFY
1680 command reply with error status to client who sent
1681 private message with invalid client ID.
1683 Updated the protocol specification.
1685 * Added silc_server_send_command_reply to send any
1686 command reply. Affected file silcd/packet_send.[ch].
1688 * Added silc_id_payload_encode_data to encode ID payload
1689 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1691 * The server now send IDENTIFY command reply with error
1692 status if client ID in private message is invalid. Affected
1693 file silcd/packet_receive.c.
1695 * Save the server key file with server's IP address in
1696 the filename instead of hostname. The affected file is
1697 irssi/src/silc/core/client_ops.c.
1699 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1704 * Added libtool support for compiling shared objects in
1705 lib/silcsim. Affected file configure.in.pre and
1706 lib/silcsim/Makefile.am. Original patch by cras.
1708 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Pid file configuration, and server's config file fixes
1711 patch by toma. Updated CREDITS file.
1713 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Fixed silc_client_channel_message to not try to decrypt
1716 the message twice if it resolved the destination client
1717 information. This could cause of dropping one channel
1718 message. Affected file lib/silcclient/client_channel.c.
1720 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1723 lib/silcclient/client.c. This function is used when the SILC
1724 Client is run under some other scheduler, or event loop or
1725 main loop. On GUI applications, for example this may be
1726 desired to used to run the client under the GUI application's
1727 main loop. Typically the GUI application would register an
1728 idle task that calls this function multiple times in a second
1729 to quickly process the SILC specific data.
1731 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1733 * Fixed silc_server_drop() for dropping the supplementary
1734 groups as well, this could cause a security hole on some
1737 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1742 * Write PID file after dropping privileges. Added -F option
1743 to run server on foreground. A patch by debolaz.
1744 Affected files silcd/server.c, silcd/silcd.c.
1746 * Fixed MOTD to return the MOTD file server name. Affected
1747 file silcd/command.c.
1749 * Added INFO command reply handling to the Irssi SILC Client.
1750 Affected file irssi/src/silc/core/client_ops.c.
1752 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1754 * Fixed the silc_idcache_list_* routines to really support
1755 the dynamic list. Fixes a crash. Affected file is
1756 lib/silccore/silcidcache.c.
1758 * Fixed the LIST command reply to really call LIST command's
1759 pending callbacks. Affected file silcd/command_reply.c.
1761 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Update conn->local_entry->nickname after giving NICK
1764 command. Affected file lib/silcclient/command.c.
1766 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1768 * Added the [pid] option to the silcd configuration file
1770 Affected files: serverconfig.[ch] and silcd.c
1772 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Save fingerprint in WHOIS command reply in server.
1775 Affected file silcd/command_reply.c.
1777 * Fixed NICK commands pending callback registration.
1778 Affected file lib/silcclient/command.c.
1780 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Use ++server->cmd_ident when sending commands in server,
1783 instead of random number. Affected file silcd/command.c.
1785 * Fixed GETKEY command reply to call actually GETKEY pending
1786 command callbacks. Affected file silcd/command_reply.c.
1788 * A bit stricter check for nicknames. Check for same nickname
1789 in NICK command also. Affected file silcd/command.c.
1791 * Do not call INFO command everytime client ID changes, only
1792 during first connecting. Affected file lib/silcclient/client.c.
1794 * Set the new nickname only after successful command reply for
1795 NICK command is returned by server. Affected file
1796 lib/silcclient/command.c.
1798 * Remove nicknames from nicklist during server_signoff notify.
1799 Should fix /NAMES bit more. The affected file is
1800 irssi/src/silc/core/silc-channels.c.
1802 * Added `fingerprint' field to the SilcIDListData in the
1803 silcd/idlist.h to hold the fingerprint of the client's
1806 Send the fingerprint of the client's public key in WHOIS
1809 Affected files silcd/command.c, and silcd/idlist.[ch].
1811 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1812 create fingerprint from given data.
1814 * Show the fingerprint of the client's public key in WHOIS.
1815 Affected files irssi/src/module-formats.[ch] and
1816 irssi/src/silc/core/client_ops.c.
1818 * Format the multiple same nicknames also during JOIN and
1819 NICK_CHANGE notifys. Affected file is
1820 lib/silcclient/client_notify.c.
1822 * Do not print error on screen for invalid private message
1823 payload since it can come if someone is sending private
1824 messages with wrong key. Affected file
1825 lib/silccore/silcprivate.c.
1827 * Fixed multiple concurrent /PING crash. Affected file
1828 lib/silcclient/command.c.
1830 * Changed the wrong ID encoding. All IP addresses must be
1831 in MSB first order in encoded format. They were encoded
1832 wrong and was in LSB format. Affected files are
1833 silcd/serverid.c, lib/silcutil/silcutil.c.
1835 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1837 * Call the `connect' client operation through the scheduler
1838 in case of error. Affected file lib/silcclient/client.c.
1840 * Call the `failure' client operation even if the error
1841 occurred locally during a protocol. Affected file is
1842 lib/silcclient/protocol.c.
1844 * Added support of sending LIST command to router from normal
1845 server. This way normal server can get list of all channels
1846 in the network too. Fixed the channel list sending in the
1847 server too. Affected files are silcd/command.c, and
1848 silcd/command_reply.[ch].
1850 * Added silc_server_update_channels_by_server and
1851 silc_server_remove_channels_by_server. They are used during
1852 disconnection of primary router and in backup router protocol.
1853 Affected file silcd/server_util.[ch], silcd/server.c and
1854 silcd/server_backup.c.
1856 * Fixed channel adding to global list in IDENTIFY command
1857 reply in server. Affected file silcd/command_reply.c.
1859 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * If the incoming packet type is REKEY or REKEY_DONE process
1862 that packet always synchronously. Fixes yet another MAC
1863 failed error on slow (dialup) connections. Affected file
1864 lib/silcclient/client.c and silcd/server.c.
1866 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Call check_version SKE callback for initiator too. Affected
1869 file lib/silcske/silcske.c.
1871 * Implemented fix for security hole found in the SKE that was
1872 fixed in the specification few days back; the initiator's
1873 public key is now added to the HASH value computation.
1874 Added backwards support for the old way of doing it too, for
1875 old clients and old servers. Affected file is
1876 lib/silcske/silcske.c.
1878 * Enabled mutual authentication by default in SKE. If initiator
1879 is not providing mutual authentication the responder will
1880 force it. This will provide the proof of posession of the
1881 private key for responder. The affected files are
1882 lib/silcclient/protocol.c and silcd/protocol.c.
1884 * Do not cache anymore the server's public key during SKE.
1885 We do mutual authentication so the proof of posession of
1886 private key is done, and if the server is authenticated in
1887 conn auth protocol with public key we must have the public
1888 key already. Affected file silcd/protocol.c.
1890 * Added new global debug variable: silc_debug_hexdump. If
1891 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1892 file lib/silcutil/silclog.[ch].
1894 * Fixed compilation warning due to char * -> const char *.
1895 Affected files lib/silcutil/silcnet.h, and
1896 lib/silccore/silcauth.[ch].
1898 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Fixed CMODE command when new channel key was created. If
1901 the creation failed the old key was removed. Next time giving
1902 same command would crash the server since the old key was
1903 freed already. Affected file silcd/command.c.
1905 * Fixed the silc_server_announce_get_channels to not crash
1906 on reconnect. Affected file silcd/server.c.
1908 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Added silc_log_set_debug_string function to set a regex
1911 string to match for debug output. Only the function names,
1912 or filenames matching the given debug string is actually
1913 printed. This way it is possible to filter out those debug
1914 strings that user is not interested in.
1916 Fixed a bug in silc_string_regexify.
1918 Affected files lib/silcutil/silclog.[ch], and
1919 lib/silcutil/unix/silcunixutil.c.
1921 * Changed the -d options in both server and Irssi SILC client
1922 to take the debug string as argument. Affected files
1923 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1925 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Added silc_hash_babbleprint to create a Bubble Babble
1928 Encoded fingerprint. The encoding is developed by Antti
1929 Huima (draft-huima-babble-01.txt), and it creates human
1930 readable strings out of binary data. Affected file
1931 lib/silccrypt/silchash.[ch].
1933 * Print the babble print now in addition of fingerprint as well
1934 in Irssi SILC client. Affected files are
1935 irssi/src/fe-common/silc/module-formats.[ch],
1936 irssi/src/fe-common/silc/core/client_ops.c.
1938 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Fixed a security problem found in SKE. The initiator's
1941 public key too is now added to the HASH hash value creation
1942 which is signed by the responder to create the SIGN value.
1943 This will prevent anyone in the middle to lie to the responder
1944 about the initiator's public key. If this is done now, the
1945 man in the middle will get caught. Updated the protocol
1948 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Better installation directory handling. Configure module
1951 paths and other paths automatically to example_silc* files
1952 in doc/. A patch by toma.
1954 * Fixed compiler warning from MPI library, and from SILC RNG.
1957 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1958 It can be configured with ./configure. A patch by toma.
1960 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Find correct make to use in prepare-clean. A patch by
1963 toma. Affected file prepare-clean.
1965 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1967 * Added irssi variables use_auto_addr, auto_bind_ip,
1968 auto_bind_port and auto_public_ip.
1970 * Changed the interface for silc_client_send_key_agreement
1971 in lib/silcclient/silcapi.h
1975 irssi/src/silc/core/silc-core.c
1977 lib/silcclient/silcapi.h
1978 irssi/src/silc/core/silc-channels.c
1979 lib/silcclient/client_keyagr.c
1982 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Added silc_pkcs_public_key_compare to compare two
1985 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1987 * Check that the client who set the founder mode on the
1988 channel is the same client that is giving the founder
1989 mode to itself. It is done by comparing the saved public
1990 key (it is saved even in the authentication is passphrase).
1991 Affected file silcd/command.c.
1993 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Do not process packet for disconnected socket connection.
1996 Affected file lib/silccore/silcpacket.c.
1998 * Process the DISCONNECT packet through scheduler in the
1999 client library. Affected file lib/silcclient/client.c.
2001 * Fixed the silc_client_packet_parse to not to increase
2002 the packet sequence number if the conn->sock and the
2003 current socket connection is not same. This can happen
2004 for example during key agreement when the conn includes
2005 multiple socket connections (listeners). Affected file
2006 lib/silcclient/client.c.
2008 * The sender of the file transfer request now provides also
2009 the pointer (listener) for the key exchange protocol. If
2010 the listener cannot be created then it sends empty key
2011 agreement and lets the receiver provide the listener.
2013 Added `local_ip' and `local_port' arguments to the
2014 silc_client_file_send. If they are provided they are used,
2015 if not then it will attempt to find local IP address, if
2016 not found or bind fails then the remote client will provide
2019 Affected files are lib/silcclient/client_ftp.c and
2020 lib/silcclient/silcapi.h.
2022 * Extended the FILE SEND command to support defining the
2023 local IP and port for key exchange listener. They are
2024 optional. Affected file irssi/src/silc/core/silc-servers.c.
2026 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Defined to WHOIS command reply the sending of fingerprint
2029 of the client's public key (if the proof of posession of the
2030 corresponding private key is verified by the server).
2031 Updated to the protocol specification.
2033 * Added support of receiving the client's public key's
2034 fingerprint in command reply in client library. Affected
2035 file is lib/silcclient/command_reply.c, and
2036 lib/silcclient/idlist.[ch].
2038 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Do not send over 128 chars long nickname to the server
2041 in NICK command. Affected file lib/silcclient/command.c.
2043 * Do not send over 256 chars long channel names to the server
2044 in JOIN command. Affected file lib/silcclient/command.c.
2046 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Assure that silc_server_close_connection cannot be called
2049 twice for same socket context. Affected file is
2052 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Send error message to application if opening file for
2055 writing during file transfer fails. Affected file is
2056 lib/silcclient/client_ftp.c.
2058 Remove all file transfer sessions for a client that we're
2059 removing from ID cache.
2061 Affected file is lib/silcclient/client_ftp.c.
2063 * Fixed silc_net_addr2bin to return correct address. Affected
2064 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2066 * Fixed file transfer session removing on signoff notify.
2067 Affected file irssi/src/silc/core/silc-servers.c.
2069 * Added the SilcClientFileError to be returned in the monitor
2070 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2071 Affected file lib/silcclient/silcapi.h.
2073 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Fixed a crash in silc_client_ftp_free_sessions and
2076 silc_client_ftp_session_free_client. Affected file
2077 lib/silcclient/client_ftp.c.
2079 * Added `disabled' field in the SilcChannelEntry in the server
2080 to indicate if the server entry is disabled. Affected file
2081 silcd/idlist.h, silcd/command[_reply].c.
2083 * SILC server adds now /var/run/silcd.pid everytime it is
2084 started. Affected file silcd/silcd.c.
2086 * Added silc_server_packet_send_clients to send a packet to
2087 the provided table of client entries. Affected file
2088 silcd/packet_send.[ch].
2090 * Fixed a crash in client resolving in client_prvmsg.c in
2091 client library. Affected file lib/silcclient/client_prvmsg.c.
2093 * Do not actually remove the client directly from ID cache
2094 during SERVER_SIGNOFF, but invalidate it. This way we
2095 preserve the WHOWAS info for the client. Affected file
2096 silcd/server_util.c.
2098 * Fixed SERVER_SIGNOFF notify handling in the server. The
2099 server is now able to process incoming SERVER_SIGNOFF notify
2100 for a server that it doesn't even know about. It will remove
2101 the clients provided in the notify. Affected file
2102 silcd/packet_receive.c.
2104 * Check for partial packet in data queue after every packet that
2105 was found from the queue. Return and wait for more data if
2106 there is partial data in queue. Affected file is
2107 lib/silccore/silcpacket.c.
2109 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * Added SilcClietFileError enum to indicate error in
2112 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2113 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2114 Affected files lib/silcclient/silcapi.h and
2115 lib/silcclient/client_ftp.c.
2117 * Check that newsize in silc_buffer_realloc is larger than
2118 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2120 * Added better monitor of file transfers. It now monitors
2121 key agreement protocol during the file transfer too. Added
2122 error reporting too. Affected files
2123 irssi/src/silc/core/silc-servers.c,
2124 irssi/src/fe-common/silc/module-formats.[ch].
2126 * Wrote a help file for FILE command.
2128 * Added silc_rng_global_get_byte_fast to get not-so-secure
2129 random data as fast as possible. Random data is read from
2130 /dev/urandom if available and from the SILC RNG if not
2131 available. It is used in padding generation. Affected file
2132 lib/silccrypt/silcrng.[ch].
2134 * All packets in client library are now processed synchronously.
2135 Optimized packet processing a lot. Affected file
2136 lib/silcclient/client.c.
2138 * All server connection packets are processing synchronously
2139 now in server, to optimize packet processing. Affected file
2142 * Include files are installed now only in Toolkit distribution
2143 if make install is given. Affected files: all Makefile.am's.
2145 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2147 * Assure that silc_client_notify_by_server_resolve does not
2148 resolve the client information multiple times. If it cannot
2149 be found by the first it cannot be found at all. Affected
2150 file lib/silcclient/client_notify.c.
2152 * Fixed WHOWAS command reply calling. Affected file
2153 lib/silcclient/command_reply.c.
2155 * Removed all references to silc_idlist_get_client from the
2156 Irssi SILC client since that call is internal call used by
2157 the library. The Irssi SILC client will use now client
2158 retrieval functions found in silcapi.h.
2160 * Fixed a bug in resolving nickname info before sending
2161 private message. It used freed memory. Affected file
2162 irssi/src/silc/core/silc-servers.c.
2164 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Assure my_channels statistics cannot go negative in server.
2167 Affected files silcd/server.c, silcd/server_util.c.
2169 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2183 * Added silc_net_localip to return local host's IP address.
2184 Affected file lib/silcutil/silcnet.[ch].
2186 * If key exchange or rekey protocol is active for a connection
2187 parse all packets syncronously since there might be packets
2188 in packet queue that we are not able to process without first
2189 processing packets before them. Affected file silcd/server,
2190 lib/silcclient/client.c.
2192 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2193 whether library should continue processing the packet.
2194 Affected file lib/silccore/silcpacket.h.
2196 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2225 lib/silcutil/silcutil.[ch].
2227 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Resolve the client info when received private message or
2230 channel message for a client which nickname we don't know.
2231 Affected files lib/silcclient/client_prvmsg.c and
2232 lib/silcclient/client_channel.c.
2234 * Do not crash in /KEY if client is not connected. Affected
2235 file irssi/src/silc/core/silc-channels.c.
2237 * Added SilcClientStatus field to the SilcClientEntry in the
2238 lib/silcclient/idlist.h.
2240 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2241 is incomplete and is being resolved, it won't be resolved
2244 Make sure also that USERS command reply does not resolve
2245 twice information. Affected file is
2246 lib/silcclient/command_reply.c.
2248 Make sure that silc_client_get_clients_by_list does not
2249 resolve twice same information.
2251 * Check for valid client->id in the silc_server_free_client_data.
2252 Affected file silcd/server.c.
2254 * Fixed /GETKEY nick@server not to crash if the server entry
2255 is not found. Affected file lib/silcclient/command.c.
2257 * Fixed the silc_server_check_cmode_rights to check the
2258 requested modes correctly. Affected file silcd/command.c.

2262 * Better checks for non-printable chars in nick added.
2263 Affected file silcd/command.c.
2265 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Call the silc_server_udpate_servers_by_server in the
2268 primary router that comes back online in the backup resuming
2269 protocol. Otherwise it routes packets wrong. Affected file
2270 silcd/server_util.[ch], silcd/server_backup.c.
2272 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2275 lib/silcutil/silcbuffmt.[ch].
2277 * Redefined the SILC packet header to include the padding
2278 length. Affected file lib/silccore/silcpacket.[ch].
2280 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2281 length for maximum padding up to 128 bytes). Affected
2282 file lib/silccore/silcpacket.h.
2284 * Removed all backwards support for old 0.5.x MAC thingies.
2285 The SILC packet header change makes it impossible to be
2286 backwards compatible.
2288 * Send the ENDING packet with timeout in the backup resuming
2289 protocol. This is to assure that all routers has connected
2290 to the primary router. Affected file silcd/server_backup.c.
2292 * Changed the RNG to take the first IV from random data. It
2293 used to take it from zero actually. Changed the RNG also
2294 to use /dev/urandom during session. /dev/random is used
2295 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2297 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2299 * Changed the SILC packet header to have the first two bytes
2300 (the packet length) encrypted. Affected files aroung the
2301 code tree, lib/silccore/silcpacket.[ch]. Removed the
2302 SilcPacketCheckDecrypt callback. It is not needed anymore
2303 since the silc_packet_receive_process will determine now
2304 whether the packet is normal or special.
2306 * Implemented the unidirectional MAC keys. Affected files
2307 lib/silcske/silcske.c, silcd/protocol.c and
2308 lib/silcclient/protocol.c.
2310 * Implemented the packet sequence number to the MAC computation.
2311 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2312 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2313 lib/silcclient/protocol.c.
2315 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Allow backup router to announce servers. All servers
2318 announced by backup router are added to the global list
2319 automatically. Update hte server's socket to our primary
2320 router also when backup router announces a server.
2321 Affected file silcd/packet_receive.c.
2323 * Do not update the client->router in the function
2324 silc_server_udpate_clients_by_server if the client is on
2325 global list. We might fail to find any specific server
2326 for locally connected clients and local cell clients. They
2327 should still use the `from' and not `to' as client->router.
2328 This fixes backup router resuming protocol. Affected file
2329 silcd/server_util.c.
2331 * Decrease channel statistics count only if the channel
2332 deletion worked. Affected files are silcd/server.c and
2333 silcd/server_util.c.
2335 * Added silc_server_update_servers_by_server to update origin
2336 of all server entries. Used during backup router protocol.
2337 Affected files silcd/server_util.[ch], silcd/server.c. and
2338 silcd/backup_router.c.
2340 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2341 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2342 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2343 lib/silccrypt/silchmac.c.
2345 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Assure that router cannot reroute the same channel message
2348 to the sender. Affected file silcd/packet_receive.c.
2350 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2352 * Made better checks that the channel message is not sent
2353 to the router it came from. Affected file is
2354 silcd/packet_send.c. Fixed memory leak too.
2356 * Announce informations for incoming router connection, but
2357 only after checking if it is replaced by backup router.
2358 Affected file silcd/packet_receive.c.
2360 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Fixed the backup resuming protocol to work in multiple
2363 router environment. Affected file silcd/server_backup.c.
2365 * Route packet only to one router in the function
2366 silc_server_packet_send_to_channel. Affected file is
2367 silcd/packet_send.c.
2369 * Fixed silc_server_send_notify_dest to set the broadcast
2370 flag. Fixed the silc_server_send_notify_topic to actually
2371 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2372 Affected file silcd/packet_send.c.
2374 * Changed the SFTP Filesystem interface. Changed the
2375 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2376 the filesystem operation function. The SilcSFTPFilesystem
2377 is now a context that is allocated by all filesystem allocation
2378 functions and it already includes the operations structure
2379 and filesystem specific context. It is given as argument
2380 now to the silc_sftp_server_start. This made the interface
2381 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2382 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2384 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Changed the backup router adding and getting interfaces
2387 in the server. The router that will be replaced by the
2388 specified backup router is now sent as argument. Affected
2389 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2392 * Added silc_net_addr2bin_ne to return the binary form of
2393 the IP address in network byte order. Affected files
2394 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2396 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Check for existing server ID in silc_server_new_server
2399 and in silc_server_connect_to_router_final and remove the
2400 old entry if it exists. Affected file silcd/packet_receive.c,
2403 * Send the channel message always to only one router, either
2404 in upstream or downstream. Affected file is
2405 silcd/packet_send.c.
2407 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Wrote the definition of the backup resuming protocol to the
2410 protocol specification.
2412 * Removed one redundant channel key generation from normal
2413 server during joining procedure. Removed one redundant
2414 channel key sending from server to router during joining
2415 procedure. Affected file silcd/command.c.
2417 * Made minor bugfixes to the backup router resuming protocol.
2418 Affected file silcd/server_backup.c, server.c.

2423 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2426 * Implemented the backup resuming protocol that is used to
2427 resume the primary router position in the cell after the
2428 primary router comes back online. Affected files
2429 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2430 and silcd/server_util.[ch].
2432 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Sleep two (2) seconds after sending QUIT command to server.
2435 Affected file lib/silcclient/command.c.
2437 * Assure that if outgoing data buffer is pending do not force
2438 send any data. Affected file silcd/packet_send.c.
2440 * Assure that if outgoing data buffer is pending do not force
2441 send any data. Affected file lib/silcclient/client.c.
2443 * Implemented the backup router support when the primary router
2444 goes down. The servers and routers can now use the backup
2445 router as new primary router without loosing connectivity.
2447 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2450 in the server to indicate disabled entry. All data read
2451 from the connection will be ignored and no data is sent
2452 for entry that is disabled. Affected files are
2453 silcd/idlist.h, silcd/server.c.
2455 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Created SFTP client and server test programs in the
2458 lib/silcsftp/tests directory.
2460 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Implemented memory filesystem (virtual filesystem) for
2463 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2466 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Implemented the SFTP (SSH File Transfer Protocol) to the
2469 lib/silcsftp. It includes SFTP client and SFTP server
2472 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Moved lib/silccore/silcprotocol.[ch] to the
2475 lib/silcutil library.
2477 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2478 take variable argument list pointer as argument. Affected
2479 file lib/silcutil/silcbuffmt.[ch].
2481 * Added silc_buffer_set function that is used to set data
2482 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2483 Affected file lib/silcutil/silcbuffer.h.
2485 * Changed various routines in the core library to use the new
2486 silc_buffer_set instead of allocating new buffer only for
2489 * Added 64-bit value formatting and unformatting support to the
2490 silc_buffer_[un]format routines. Affected file is
2491 lib/silcutil/silcbuffmt.[ch].
2493 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2494 to includes/bitmove.h.
2496 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * Fixed channel user mode saving in client library. Affected
2499 file lib/silcclient/command[_reply].c.
2501 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Defined the file transfer to the SILC Protocol. Added
2504 new packet type SILC_PACKET_FTP and defined File Transfer
2505 Payload. The mandatory file transfer protocol is SFTP
2506 (SSH File Transfer Protocol). Affected file in addition
2507 of the internet draft is lib/silccore/silcpacket.h.
2509 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2510 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2511 is used as part of backup router protocol when the primary
2512 router of the cell is back online and wishes to resume
2513 the position as primary router.
2515 * Redefined the MAC generation keys in the protocol. The
2516 same key is not used anymore in both direction. Both
2517 direction will now use different keys for sending and
2518 receiving. This fixes a potential security flaw. This
2519 change causes incompatibilities in the protocol.
2521 * Redefined also the MAC computation from the packet.
2522 An packet sequence number is now added to the MAC
2523 computation. This prevents possible replay attacks against
2524 the protocol. This change too causes incompatibilities
2527 Added `sequence' field to the SilcPacketContext to hold
2528 the current sequence number for the packet.
2530 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Added `created' field to the SilcIDListData in the file
2533 silcd/idlist.h to indicate the time when the entry was
2536 * Added `created' field to the SilcChannelEntry too. Affected
2537 file silcd/idlist.h.
2539 * Added `creation_time' aguments to all the announcement functions
2540 in the server. If it is provided then only the entries that
2541 was created after the provided time frame are actually
2542 announced. Affected file silcd/server.[ch].
2544 * The protocol says that the Channel ID's IP address must be
2545 based on the router's IP address. Added check for this in
2546 the silc_server_new_channel when processing incoming New Channel
2547 Payload. Affected file silcd/packet_receive.c.
2549 * Print out the correct version with --version in SILC client.
2550 Affected file irssi/src/silc/core/silc-core.c.
2552 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Fixed WHOWAS command to check for completnes of the client
2555 entry always, not just when the command is coming from client.
2556 Affected file silcd/command.c.
2558 * Added new function silc_server_packet_queue_purge to purge the
2559 outgoing data queue to the network. After the function returns
2560 it is guaranteed that the outgoing packet queue is empty.
2561 Affected file silcd/packet_send.[ch].
2563 * Purge the outgoing packet queue in the rekey protocol's final
2564 callback to assure that all rekey packets go to the network
2565 before quitting the protocol. Affected file silcd/server.c.
2567 * Added silc_client_packet_queue_parse as similar function as
2568 in server to the client library. The affected file is
2569 lib/silcclient/client.c.
2571 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2573 * Splitted silcd/server.c and created silcd/server_util.[ch]
2574 for utility functions.
2576 * Added new socket flag SILC_SF_DISABLED to indicate that the
2577 connection is open but nothing can be sent to or received from
2578 the connection. Affected file lib/silcutil/silsockconn.[ch].
2579 The checking for disabled socket is checked in the low level
2580 silc_socket_write and silc_socket_read functions.
2582 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Allow only nicknames and channel names that fits into the
2585 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2587 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * When processing JOIN command reply in server check that if
2590 the channel exists in our global list we'll move it the local
2591 list. Affected file silcd/command_reply.c.
2593 * Fixed the check whether client is joined on the channel already
2594 in JOIN command. Affected file lib/silcclient/command.c.
2596 * Fixed the JOIN command reply to check whether the channel
2597 already exists. Affected file lib/silcclient/command_reply.c.
2599 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Added silc_ske_status_string to map the SKE error numbers
2602 to readable strings. The affected files are
2603 lib/silcske/silcske[_status].[ch].
2605 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Do not show the private channels on the WHOIS channel list
2608 as it is not allowed by the protocol. The affected file is
2611 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * Assure that the packet length digged from the actual packet
2614 is something sensible in the silc_packet_decrypt_rest_special
2615 in lib/silccrypt/silcpacket.c.
2617 * Free and NULL the allocated pointer in silc_hmac_alloc if
2618 the HMAC allocation fails. The affected file is
2619 lib/silccrypt/silchmac.c.
2621 * Print the selected security properties to the log files in
2622 the server. Affected file silcd/protocol.c.
2624 * Add SKE's reference counter even if calling the completion
2625 callback manually. Otherwise it goes negative, although it
2626 does not cause any problems. The affected file is
2627 lib/silcske/silcske.c.
2629 * Remove the client entry with short timeout after giving the
2630 KILL command. Affected file lib/silcclient/command.c.
2632 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2633 case all found clients are already disconnected (WHOWAS would
2634 found them) in the server. Affected file silcd/command.c.
2636 * Update the last_receive (time of last data received) to be
2637 updated only when received private or channel message so that
2638 the idle time showed in WHOIS makes more sense.
2640 * Added boolean field `valid' in to the SilcClientEntry in the
2641 client library to indicate whether the entry is valid or not.
2642 This fixes the nickname change bug on channel when changing
2643 the nickname to be same than the old (like nick to Nick) the
2644 nickname formatter doesn't set the new nick anymore to Nick@host.
2645 Affected file lib/silcclient/idlist.[ch].
2647 * Now actually fixed the nickname changing on disconnection.
2648 Added new function silc_change_nick to the Irssi SILC Client.
2649 Affected file irssi/src/silc/core/client_ops.c,
2650 irssi/src/silc/core/silc-nicklist.[ch].
2652 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Check that the public key exists in the GETKEY command before
2655 trying to encode it. Affected file silcd/command.c.
2657 * Print some notifications on received public keys with GETKEY
2658 command in the Irssi SILC Client. Affected files are
2659 irssi/src/fe-common/silc/module-formats.[ch],
2660 irssi/src/silc/core/client_ops.c.
2662 * Use IDENTIFY command to resolve the server information in the
2663 GETKEY command instead of INFO command. Affected file
2664 lib/silcclient/command.c.
2666 * All command reply functions in the client library now calls
2667 the pending command reply callbacks even if an error has
2668 occurred. The server has done this a long time and now it was
2669 time to move the client library to this as well. Now all
2670 errors can be delivered back to the pending command reply
2671 callbacks if necessary. Affected files are
2672 lib/silcclient/command[_reply].[ch].
2674 * Change the nickname on disconnection back to the username
2675 because in reconnect the server will enforce it to it anyway.
2676 Affected file irssi/src/silc/core/silc-servers.c.
2678 * Fixed a config file parsing bug in the Irssi SILC client.
2679 Affected file irssi/src/silc/core/clientconfig.c.
2681 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * When printing the channel mode on JOIN, verify that the
2684 channel key and channel's HMAC are valid. Affected file
2685 irssi/src/silc/core/client_ops.c.
2687 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2690 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2691 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2693 * Removed channel key rekey task deleting from the function
2694 silc_server_save_channel_key. Affected file silcd/server.c.
2695 Added explicit timeout task context instead that is used to
2696 delete the task if we are registering a new task before the
2697 new task has elapsed.
2699 * When channel key rekey occurs the client library now saves
2700 the old channel key for a short period of time (10 seconds) and
2701 is able to use it in case some is still sending channel
2702 messages encrypted with the old key after the rekey. Affected
2703 file lib/silcclient/[idlist.h|client_channel.c].
2705 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Added check to the silc_server_new_id_real to not accept
2708 new ID if it is the sender's own ID. Affected file is
2709 silcd/packet_receive.c.
2711 * Assure that we do not announce ourself or the one we've
2712 sending our announcements when we're router and are announcing
2713 servers to our primary router. Affected file silcd/server.c.
2715 * Fixed silc_server_command_identify_check_client to assemble
2716 correct WHOIS packet. It send corrupted WHOIS packet and
2717 caused problem with router to router connections. Affected
2718 file silcd/command.c.
2720 Fixed also silc_server_command_whois_check the same way
2721 as for the IDENTIFY command.
2723 * Added new SilcIDListStatus to the server in the SilcIDListData
2724 structure. The status now includes the current status of
2725 the entry (like registered, resolved etc.). Affected file
2726 silcd/idlist.[ch]. Defined a bunch of different status types
2727 as well. This replaced the old boolean registered field as well.
2729 Added resolve_cmd_ident field to the SilcClientEntry structure
2730 too so that if the entry is for example being resolved so
2731 another command may attach to the same pending command reply
2732 without requiring to resolve the same entry again. This concept
2733 should optimize the WHOIS and the IDENTIFY resolving under
2734 heavy load by taking away unnecessary resolving for entries
2735 that are being resolved already.
2737 Added support for adding multiple pending commands for one
2738 command idenfier. Affected file silcd/command[_reply].[ch].
2740 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2741 before deleting the data. Otherwise the hash table will have
2742 freed data in comparison functions. Affected file is
2743 silcd/command_reply.c.
2745 * Fixed silc_idlist_replace_client_id to add the new entry to
2746 the cache with NULL nickname. Otherwise there will be invalid
2747 memory as the nickname after the nickname is freed. Affected
2748 file silcd/packet_receive.c.
2750 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2751 saved into wrong slots because the previous number of entries
2752 was not taken into account. Affected file silcd/idlist.c.
2753 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2755 * If we are router and we receive JOIN notify to a channel that
2756 does not have any users then notified client is marked as the
2757 channel founder, as it is it. The affected file is
2758 silcd/packet_receive.c
2760 * Added to the extended hash table API's table_del_*ext functions
2761 the destructor as argument too, so that the caller can decide
2762 which destructor to use or whether to use destructor at all.
2763 Affected file lib/silcutil/silchashtable.[ch].
2765 * Fixed ID Cache purging. It actually deleted the entries from
2766 the hash table after the data was freed. The hash table ended
2767 up comparing freed memory. The affected file is
2768 lib/silccore/silcidcache.c.
2770 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Fixed Irssi SILC client's KILL command's HELP syntax.
2774 * The USERS command now resolves the detailed user information
2775 if the userinfo field is missing. Affected file is
2776 lib/silcclient/command_reply.c.
2778 * Do not print error in silc_file_read if the read file does
2779 not exist. Just silently return NULL. Affected file is
2780 lib/silcutil/silcutil.c.
2782 * Fixed the silc_log_output to not wine about NULL filename
2783 and to not create some bogus " " filename. Affected file is
2784 lib/silcutil/silclog.c.
2786 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Fixed various printing bugs on the user interface in the
2789 Irssi SILC Client. Minor changes that were forgotten from
2792 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Fixed the configure.in.pre and the compilation and distribution
2795 environment to support the new autoconf 2.52. That version is
2796 now required to compile the CVS trunk.
2798 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2801 to generally parse user@fqdn format strings. Affected file
2802 lib/silcutil/silcutil.c.
2804 * Added nickname_format and nickname_force_format fields to the
2805 SilcClientParams structure. The first one defines the format
2806 for the nicknames that the library will enforce if the receives
2807 multiple same nicknames. The second one is boolean value and
2808 can be used to force the library to always enforce the format
2809 to the nicknames regardles whether there are multiple nicknames
2810 or not. This configurable formatting was employed to flexibly
2811 support accessing multiple nicknames from the user interface.
2812 The userinterface can now set the nicknames to what ever format
2813 they prefer. Affected file lib/silcclient/silcapi.h.
2815 Added function silc_client_nickname_format to the file
2816 lib/silcclient/idlist.c. It performs the nickname formatting.
2818 Added new field `hostname´ to the SilcClientEntry context.
2819 It holds the hostname of the client. Affected file is
2820 lib/silcclient/idlist.h.
2822 * Irssi SILC Client sets the nicknames in nick@hostn format.
2823 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2824 irssi/src/silc/core/silc-core.c.
2826 The WHOIS printing now also shows both the real nickname and
2827 the formatted nickname so that user knows how to access the
2828 user if there are multiple same nicknames cached. Affected
2829 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2830 printing formatting too to take the hostname now as a separate
2831 argument. The Affected file is
2832 irssi/src/fe-common/silc/modules-formats.[ch].
2834 * Changed the silc_client_get_clients_local to accept the formatted
2835 nickname as argument. It accepts the real nickname too but the
2836 formatted nickname can be used to find the true entry from
2837 multiple entries. Affected file lib/silcclient/silcapi.h and
2838 lib/silcclient/idlist.c.
2840 * Added nickname_format_parse field to the SilcClientParams.
2841 It is a callback function provided by the application to parse
2842 the nickname out of the formatted nickname string. The library
2843 calls it to get the nickname from the formatted string. Since
2844 the application generally knows better the format of the nickname
2845 string it parses it instead of the library, even though library
2846 encodes the formatted string. If the callback function is not
2847 provided then the library will use the string as is. The
2848 affected file is lib/silcclient/silcapi.h.
2850 * All the nickname strings passed to the client library in
2851 commands are now expected to be formatted nickname strings.
2852 If the command does not support the formatted nickname string
2853 it will assume that the sent string is the actual nickname.
2854 Affected file lib/silcclient/command.c.
2856 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Added public key authentication support to OPER and SILCOPER
2859 commands in the client library. Affected file is
2860 lib/silcclient/command.c.
2862 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Changed the get_auth_methdod client operation to be asynchronous.
2865 It can be async if the application resolves the authentication
2866 method from the server during the negotiation. Added new
2867 SilcGetAuthMeth completion callback that the application will
2868 call after resolving the authentication method.
2870 Added function silc_client_request_authentication_method that
2871 the application can use to resolve the authentication method
2872 from the server. Added also SilcConnectionAuthRequest callback
2873 that the library will call after the server has replied. The
2874 application can call this function if it does not know the
2875 current authentication method.
2877 Affected files are lib/silcclient/client.c and
2878 lib/silcclient/silcapi.h.
2880 * The Irssi SILC client now automatically resolves the authentication
2881 method incase any configuration information is not present (and
2882 currently there never is). The affected file is
2883 irssi/src/silc/core/client_ops.c.
2885 * Fixed public key authentication from the client library.
2886 Affected file lib/silcclient/protocol.c. Changed also the
2887 protocol specification about the public key authentication in
2888 the connection authentication protocol. The actual data to be
2889 signed is now computed with a hash function before signing.
2891 * Fixed the public key authentication from the server as well.
2892 Affected file silcd/protocol.c.
2894 * Removed the mlock()'s from the memory allocation routines.
2895 Affected file lib/silcutil/silcmemory.c. The ./configure does
2896 not check anymore for the mlock(). Affected file is
2899 * Fixed USERS command in server to allow the execution of the
2900 command for private and secret channels if the client sending
2901 the command is on the channel. Affected file silcd/command.c.
2903 * Fixed silc_client_get_clients_local to return the clients
2904 count correctly. It could return wrong value. Affected file
2905 lib/silcclient/idlist.c.
2907 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2909 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2910 types. The assembler optimizations seemed not to like 64-bit
2911 data types. The assmebler optimizations thus are now enabled
2912 also for BSD systems as opposed to only enable them for Linux.
2914 * Do not check for threads at all on BSD systems. Affected
2915 file configure.in.pre.
2917 * Removed -n and -h options from the Irssi SILC Client since
2918 they are not used in silc.
2920 * Fixed the prime generation to assure that the first digit
2921 of the generated random number is not zero since our conversion
2922 routines does not like number strings that starts with zero
2923 digit. If zero digit is seen the random number is regenerated.
2924 This caused some corrupted RSA keys when the zero first digit
2925 was met. Affected file lib/silcmath/silcprimegen.c.
2927 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Fixed WIN32 configuration in the ./configure script.
2930 Fixed to include xti.h on environments that has it.
2931 Patches by Carsten Ilchmann and andrew.
2933 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Changed the silc_id_create_client_id to be collision
2936 resistant. It is now assured that there cannot be created
2937 two same client ID's. I suspect that some weird bugs in
2938 the server were actually caused by duplicate Client IDs.
2939 Affected file silcd/serverid.[ch]. A router receiving
2940 new ID now also assures and informs the sending server
2941 if the ID caused collision.
2943 * Changed the silc_id_create_channel_id to also assure that
2944 there are no collisions.
2946 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Statement about ignoring the Mutual Authentication flag when
2949 performing rekey with PFS was a bit misleading. It is ignored
2950 if it was set in the initial negotiation, it cannot be even
2951 set in the rekey. Fixed in the ke-auth draft. Started the
2952 new versions of the protocol drafts in the doc/.
2954 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2956 * Fixed a bug in silc_client_command_identify_save when saving
2957 new channel information. The channel name was no duplicated
2958 and caused crash on exit. Affected file is
2959 lib/silcclient/command_reply.c.
2961 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Fixed the getkey command handling in the server. Send just
2964 empty OK reply to the sender if the key could not be fetched
2965 (but everything else was ok, like the key just was not available).
2966 Changed the public key parameter to optional in the protocol
2967 specs so that empty OK reply can be sent. Affected file
2970 Added a message to Irssi SILC client to tell to user if the
2971 server did not return a public key.
2973 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Fixed a channel key regeneration bug. It registered new
2976 timeout tasks exponentially until all system resources were
2977 used. Affected file silcd/server.c.
2979 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Added the SILC Document generator to the scripts/silcdoc.
2982 It can be used to generate the Toolkit Reference Manual out
2983 of the source tree. Internally it will also use the RoboDoc
2984 generator now imported in util/robodoc.
2986 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Added couple of return's in rekey protocol if error orccurred
2989 during the protocol. The execution must be terminated.
2990 Affected file silcd/protocol.c. Also, terminate the protocol
2991 always with timeout.
2993 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * The client's Client ID was created initally from the wrong
2996 nickname (it could have been in format nick@host) in the
2997 silc_server_new_client. Affected file silcd/packet_receive.c
2999 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Added some SILC_LOG_ERROR's to various error conditions
3002 if client could not be added to ID cache. Affected files
3003 silcd/packet_receive.c and silcd/server.c.
3005 * When client's sock->user_data is freed, NULL also the
3006 client->router and client->connection pointers. Added check
3007 for these pointers being NULL to various places around the
3008 code. Affected file silcd/server.c.
3010 * Added client->data.registered == TRUE checks to various
3011 places around the code to assure that unregistered client's
3012 are not handled when it is not allowed. Affected file
3015 * Added `bool registered' fields to all
3016 silc_idlist_[server|client]_get_* routines to indicate whether
3017 the fetched client needs to be registered or not. Affected
3018 file silcd/idlist.[ch].
3020 * Add your own entry as registered to the ID cache in the
3021 server. Affected file server.c.
3023 * Fixed a bug in silc_server_new_server. The SilcServer was
3024 set as the new server's context instead of SilcServerEntry.
3025 This naturally caused some weird bugs.
3027 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Do not delete the channel rekey task when adding it
3030 for in silc_server_create_channel_key.
3032 * Changed the silc_server_create_channel_key to return
3033 TRUE or FALSE to indicate the success of the channel key
3036 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Fixed MSVC++ project files and added missing files to
3039 Makefiles under win32/.
3041 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Do not add TCP_NODELAY flag if the operating system
3044 does not have it defined. Affected files are
3045 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3047 * Fixed buffer overflow from Irssi SILC Client. Affected
3048 file irssi/src/fe-common/core/themes.c.
3050 * Fixed double free in client library in the file
3051 lib/silcclient/client.c when disconnecting from server.
3053 * Applied double free patch from cras to Irssi SILC client.
3054 Affected files irssi/src/core/[modules/expandos].c
3056 * Fixed the disconnection handling to Irssi SILC Client.
3057 The application must call silc_client_close_connection
3058 in ops->connect client operation in case of failure of
3059 the connection. Affected file is
3060 irssi/src/silc/core/client_ops.c.
3062 * Do not set sock->protocol to NULL in the function
3063 silc_client_close_connection after executing the protocol's
3064 final callback since the sock might not be valid anymore.
3065 Affected file lib/silcclient/client.c.
3067 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Do not enable SILC_THREADS if the linking with libpthread
3070 did not happen. Affected file configure.in.pre.
3072 * Added notion to protocol specification that server must
3073 verify the sent authentication payload with CMODE when
3074 setting the channel founder key. Implemented it to the
3075 server. Affected file silcd/command.c.
3077 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3079 * Added _EXTRA_DIST SILC distribution variable to the
3080 distributions file. It is used to conditionally add extra
3081 files or directories to the specific distribution. Affected
3082 files ./prepare, Makefile.am.pre and distributions.
3084 Removed the `_' from the start of the distribution names.
3087 * Added README.WIN32 for instructions to compile the Toolkit
3090 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Fixed a double free in disconnection in the server. Affected
3093 file is silcd/server.c.
3095 * Fixed the lib/silcske/groups.c to work now also with GMP
3096 MP library. The string conversion did not work when using
3097 specific base and the base is indicated in the string as well.
3099 * Created win32/ directory which now includes MSVC++ specific
3100 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3101 It will appear only in the toolkit distribution
3103 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3105 * Changed the key material distribution function in case when
3106 the hash output is too short. The data is now concatenated
3107 a bit differently than it used to. Made the change to the
3108 SKE protocol specification.
3110 * Added better GMP detection to configure.in.pre. A patch
3113 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Fixed a minor bug in SKE that might cause some problem on
3116 some platforms. Affected file lib/silcske/silcske.c.
3118 * Added the cookie checking for initiator in the SKE. It checks
3119 that the responder returns the sent cookie unmodified. The
3120 affected file is lib/silcske/silcske.c. Added new SKE
3121 error type INVALID_COOKIE that can be sent during the
3122 negotiation. Fixed some memory leaks as well.
3124 * Added the "invalid cookie" error message to Irssi SILC client's
3127 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Added `task_max' field to the SilcClientParams to indicate
3130 the maximum tasks the scheduler can handle. If set to zero,
3131 default values are used. Affected file lib/silcclient/silcapi.h.
3133 * Fixed memory leaks in silc_client_close_connection. Affected
3134 file lib/silcclient/client.c.
3136 * Added silc_client_del_client_entry to client library to free
3137 all memory of given client entry. Affected file is
3138 lib/silcclient/idlist.[ch].
3140 * Added new functions silc_client_del_channel and
3141 silc_client_del_server to delete channel and server entries.
3142 Affected file lib/silcclient/[silcapi.h/idlist.c].
3144 * Removed silc_client_del_client_by_id from silcapi.h.
3146 * Fixed the INFO command to return the server's own info
3147 correctly when querying by Server ID. Affected file is
3150 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3152 * Removed the non-blocking settings in WIN32 code in the
3153 silc_sock_[read/write] and added SleepEx instead. Affected
3154 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3155 of input data is now checked with FIONREAD and ioctlsocket.
3157 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Call silc_schedule_task_del_by_context in the
3160 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3161 Affected file lib/silccore/silcprotocol.c.
3163 * Call silc_protocol_cancel for active protocols in the
3164 silc_server_close_connection if the funtion
3165 silc_server_free_sock_user_data has not been called.
3166 Affected file silcd/server.c.
3168 * Generic tasks cannot be deleted using the del_by_fd
3169 task deleting function since generic tasks does not match
3170 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3172 * Added a notion to SILCOPER help file that the SILCOPER works
3173 only on router server, not on normal server.
3175 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3177 * Added for WIN32 support for the new scheduler as well.
3178 Affected file lib/silcutil/win32/silcwin32schedule.c.
3180 * Fixed the SHA1 implementation to work on various platforms.
3182 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3185 API. It is part of the scheduler now. Everything else is
3186 as previously but some functions has changed their names.
3187 Checkout the lib/silcutil/silcschedule.h for the interface.
3188 Updated all applications to use the new interface. Affected
3189 files are lib/silcutil/silcschedule.[ch].
3191 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3193 * Found a bug in the SKE implementation. The HASH value,
3194 specified by the protocol, was not computed correctly. The
3195 public key of the responder was not added to the computation
3196 even though it is mandatory. Affected file lib/silcske/silcske.c.
3197 This unfortunately causes incompatibilities with older
3198 clients and servers.
3200 * Added WIN32 specific network init and uninit functions:
3201 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3202 the Winsock2. Affected file lib/silcutil/silcnet.h and
3203 lib/silcutil/win32/silcwin32net.c.
3205 * Set the socket always to nonblocking mode on WIN32 after
3206 reading data or writing data. Affected file is
3207 lib/silcutil/win32/silcwin32sockconn.c.
3209 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3211 * Fixed various compilation problems under WIN32. Affected
3212 files lib/silcutil/win32/silcwin32thread.c and
3213 lib/silcutil/win32/silcwin32schedule.c.
3215 * Removed all _internal.h #includes from public header
3216 files. Internal headers must never be included from
3219 Removed also the lib/silcske/payload_internal.h file.
3221 * All include files that may be needed (public and some others
3222 included by the public headers) by application developers are
3223 now copied to the ./includes directory. It does not copy any
3224 internal headers. Affected file Makefile.defines.pre and all
3225 Makefile.am's under lib/ and subdirs.
3227 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Do not change the ~/.silc directory's permissions automatically.
3230 Affected file irssi/src/silc/core/clientutil.c.
3232 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3234 * Do not cancel the protocol in silc_server_close_connection
3235 it might cause recursion. Now cancelled in the function
3236 silc_server_free_sock_user_data. Affected file silcd/server.c.
3238 * Fixed the silc_server_remove_clients_by_server to regenerate
3239 the channel keys correctly finally. Added also new function
3240 silc_server_remove_clients_channels to actually do it.
3241 Affected file silcd/server.c.
3243 * Fixed the silc_server_new_channel to not crash by giving
3244 wrong router to the new channel. Affected file is
3245 silcd/packet_receive.c.
3247 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3250 which is given as argument to the silc_client_alloc now.
3251 It can be used to configure the client and set various parameters
3252 that affect the function of the client.
3254 * The USERS command in server did not check whether the channel
3255 is private or secret. Affected file silcd/command.c.
3257 * Added new argument to the USERS command in protocol specification.
3258 The USERS command now can take the channel name as argument
3259 as well. Added support for this in client and server and
3260 updated the protocol specs.
3262 * Completed the GETKEY command in client. It can be now used
3263 to fetch also servers public key not only some clients.
3264 Affected files lib/silcclient/command[_reply].c.
3266 * Added silc_client_get_server to return server entry by the
3267 server name. Affected files lib/silcclient/silcapi.h and
3270 * Redefined the IDENTIFY command in protocol specification to be
3271 more generic. It now can be used to query information about
3272 any entity in the SILC Network, including clients, servers and
3273 channels. The query may be based either the entity's name
3274 or the ID. Added support for this in both client and server.
3276 Affected files silcd/command.c and lib/silcclient/command.c
3277 and command_reply.c.
3279 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3280 the _from_client and _from_server functions. Affected file
3283 * Added silc_client_get_channel_by_id_resolve to the file
3284 lib/silcclient/silcapi.h to resolve channel information by
3285 its ID. Added also silc_client_get_channel_by_id that
3286 does not resolve it from the server.
3288 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Added SilcServerEntry context into the client library
3291 to represent one server. The INFO command now allocates
3292 these to save the resolved server info. For now on the
3293 client library will also keep information about servers,
3294 connected and resolved with INFO.
3296 The INFO command now allocates the SilcServerEntry context
3297 and saves the server info there. The COMMAND_REPLY in
3298 the INFO now returns the parameters to application in
3299 same order as defined in the protocol specification.
3301 The entries are cached in the client->server_cache.
3303 * The INFO command is now issued after received the Client ID
3304 from the server. Affected file lib/silcclient/client.c.
3306 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3307 to the application as the mode changer might be server.
3308 It is guaranteed that NULL is not returned anymore to the
3309 application. Affected file lib/silcclient/client_notify.c.
3311 The ID Type is now also passed to the application so that
3312 it can check whether the returned entry is SilcClientEntry
3315 Added new function silc_client_get_server_by_id to return
3316 the server entry by ID. Affected files are the
3317 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3319 * Do not create the channel in the Irssi SILC Client when issuing
3320 the JOIN command but when received the sucessful JOIN command
3321 reply. Otherwise the channel might get created even though we
3322 could not join it. The Affected file is
3323 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3325 * Fixed a channel joining bug in router. The router must also
3326 check the channel modes, invite and ban lists etc. when serving
3327 the JOIN command sent by normal server. Affected file is
3328 silcd/command.c. The router now resolves the client's
3329 information from the server who sent the JOIN command if it
3330 does not know it, and processes the JOIN command only after
3333 * Changed the SilcCommandCb to take new argument; void *context2.
3334 Affected file lib/silccore/silccommand.h
3336 The second argument in the command callbacks in the server now
3337 includes the SilcServerCommandReplyContext if the command was
3338 called as pending command callback from the command reply.
3339 Otherwise it is NULL. When called as pending the status of the
3340 command reply will be checked and if it was erronous the
3341 error will be sent to the original sender of the command.
3342 This way the client always receives the error messages even
3343 though the server was actually the one who received the error
3344 when it resent the command to router, for example. Affected
3345 files silcd/command[_reply].[ch].
3347 * Fixed sending WHOWAS command's error message to client if
3348 the requested client could not be found. It was missing.
3351 * Changed the CMODE and CUMODE commands reply arguments in the
3352 protocol specification. The Channel ID is now sent in both
3353 of the commands to identify the channel. Implemented this
3354 new feature to the client and server. Affected files
3355 lib/silcclient/command_reply.c and silcd/command.c.
3357 * Made better checks for invite and ban lists in the JOIN
3358 command in server. Affected file silcd/command.c.
3360 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3362 * The server now performs the incoming host IP/DNS lookup
3363 using the silc_socket_host_lookup and thus does not block
3364 the server anymore. Affected file silcd/server.c.
3366 * Completed the multi-thread support for SILC Scheduler in
3367 the lib/silcutil/silcschedule.c.
3369 * Fixed the configure.in.pre to detect the pthread correctly
3372 * Fixed a deadlock in silc_task_queue_wakeup in the file
3373 lib/silcutil/silctask.c.
3375 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3377 * Added new function silc_schedule_wakeup that is used in
3378 multi-threaded environment to wakeup the main thread's
3379 schduler. It needs to be used when a thread adds a new task
3380 or removes a task from task queues. After waking up, the
3381 scheduler will detect the task queue changes. If threads
3382 support is not compiled in this function has no effect.
3383 Implemented the wakeup mechanism to both Unix and WIN32
3384 systems. Affected files are lib/silcutil/silcschedule.[ch],
3385 lib/silcutil/unix/silcunixschedule.c and the
3386 lib/silcutil/win32/silcwin32schedule.c.
3388 * Added new function silc_task_queue_wakeup to wakeup the
3389 scheduler by the specified task queue. Affected file
3390 lib/silcutil/silctask.[ch].
3392 * The silc_socket_host_lookup_start now wakes up the scheduler
3393 after adding the timeout task. Affected file is
3394 lib/silcutil/silcsockconn.c.
3396 * The silc_socket_host_lookup is synchronous now if the threads
3397 support is not compiled in. However, the callback is still
3398 called asyncronously through the scheduler, anyway. Affected
3399 file lib/silcutil/silcsockconn.c.
3401 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3403 * Added new function silc_socket_host_lookup to perform
3404 asynchronous IP and FQDN lookups for the socket connection.
3405 Affected files lib/silcutil/silcsockconn.[ch].
3407 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3410 that may or may not compile the mutex support in.
3412 Changed the silc_mutex_alloc interface. It allocates the
3413 mutex now to the sent pointer and returns TRUE or FALSE.
3415 Affected file lib/silcutil/silcmutex.h.
3417 * Wrote the SILC Task Queue interface to support multi-threads.
3418 Affected file lib/silcutil/silctask.[ch].
3420 * Wrote the SILC Scheduler to support multi-threads. Affected
3421 file lib/silcutil/silcschedule.c.
3423 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3425 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3426 in lib/silcutil/win32/.
3428 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Defined SILC Mutex API and SILC Thread API and implemented
3431 them for Unix. Affected files are
3432 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3433 lib/silcutil/unix/silcunixmutex.c and
3434 lib/silcutil/unix/silcunixthread.c.
3436 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Fixed the silc_server_remove_clients_by_server's channel
3439 key re-generation. The hash table handling was incorrect
3440 and would not work with many channels. Affected file is
3443 * Fixed some memory leaks around the server code.
3445 * Rewrote the silc_server_get_users_on_channel to support IPv6
3446 based Client ID's. Affected file silcd/server.c.
3448 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3449 specification. However, a separate document must be written
3450 to define the detailed signing procedure and the payload
3451 associated with the flag. Defined the flag to the
3452 lib/silccore/silcchannel.h as well.
3454 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Changed the dynamic tables to static size tables in the
3457 lib/silccrypt/silchmac.c.
3459 * Removed GCC dependencies from the code. A patch by cras.
3461 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Do not show the error "Error receiving packet bla bla"
3464 in server if it really was not an error (-2 means that reading
3465 is pending). Affected file silcd/server.c.
3467 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3469 * Fixed a possible crash in silc_server_remove_clients_by_server
3470 in silcd/server.c. Fixed there also some memory leaks.
3472 * Fixed the silc_idlist_replace_client_id. It could replace
3473 wrong key in the hash table. Affected file silcd/idlist.c.
3475 * Do not check whether there are global users on the channel
3476 if the channel->global_users is FALSE. Affected functions
3477 silc_server_remove_from_one_channel and
3478 silc_server_remove_from_channels in silcd/server.c. Also,
3479 do not check if the removed client is local as we can be
3480 sure that global client was not removed from the channel
3481 and checking for global users is not needed.
3483 * The silc_server_remove_clients_by_server now re-generates
3484 the channel keys correctly for those channels that had
3485 clients removed from them. Affected file silcd/server.c.
3487 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3489 * Found the reason of random crashes in the server. We weren't
3490 ignoring the SIGPIPE signal (which can be sent in write())
3491 and it crashed the server. Affected file silcd/silcd.c.
3493 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3495 * Assure that sock->user_data is not NULL in the function
3496 silc_server_packet_send in silcd/packet_send.c.
3498 * Disconnect the remote connection if it could not be added
3499 to any ID lists in the server. The affected file is
3502 * Check in silc_server_packet_send[_real/dest] that the
3503 socket is not disconnecting and ignore the data if it is.
3504 Affected file silcd/packet_send.c.
3506 * Define inline to __inline on native WIN32 compilation.
3507 Affected file includes/silcwin32.h.
3509 * Added some explicit type casts for inline code since MSVC
3510 require them. Affected files lib/silcutil/silcbuffer.h,
3511 lib/trq/silcdlist.h and lib/trq/silclist.h.
3513 * Print warning in log files from now on if the packet
3514 decryption fails. Affected file silcd/server.c.
3516 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Changed the `say' client operation's interface to accept
3519 new `type' argument to indicate the type of the message sent
3520 by the library. The application may filter the library's
3521 messages according the type. The affected file is the
3522 lib/silcclient/silcapi.h.
3524 * Added two new functions to lib/silcclient/silcapi.h:
3525 silc_client_del_client and silc_client_del_client_by_id.
3526 Affected file lib/silcclient/idlist.c.
3528 * Moved the clientincludes.h from includes/ to silc/ and
3529 serverincludes.h from includes/ to silcd/.
3531 * The modes for the CMODE and CUMODE are now passed as
3532 uint32 for application with COMMAND_REPLY. The affected
3533 file is lib/silcclient/command_reply.c.
3535 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * /WHOIS without arguments shows client's own information.
3538 Affected file lib/silcclient/command.c.
3540 * Changed PING to not accept any arguments. The specs
3541 says that client can ping only the connected server so
3542 requiring an argument is not needed. Affected file is
3543 lib/silcclient/command.c.
3545 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3547 * Fixed a fatal bug in private message sending and reception
3548 encryption and decryption when using private message keys.
3549 The implementation was incorrect and did not follow the
3550 specification. It causd that some of the message were
3551 lost since it did not use the sending and receiving keys
3552 as the protocol suggests. This has been fixed and will cause
3553 incompatibilities with older clients when sending private
3554 message encrypted with private message keys. Affected files
3555 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3556 and various other in Irssi SILC Client.
3558 Added `responder' boolean argument to the functions
3559 silc_client_add_private_message_key[_ske] to indicate when
3560 the key is added as responder or initiator of the key
3563 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Removed the silc_ske_check_version function and created
3566 a SilcSKECheckVersion callback. Added also a function
3567 silc_ske_set_callbacks that is now used to set all SKE
3568 callbacks. The callback functions are not given to
3569 the SKE functions anymore, but this function is used to
3572 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3574 * Added `silc_version' argument to the silc_client_alloc
3575 to define the version of the application for the library.
3576 The library will use the version string to compare it
3577 against the remote host's (usually a server) version
3578 string. Affected file lib/silcclient/silcapi.h
3580 * Added the KE protocol context to Key Agreement context
3581 in client library so that we can abort the SKE if it
3582 is in process when we get timeout. Affected file is
3583 lib/silcclient/client_keyagr.c.
3585 * Do not resolve the client ID forever if it returns in the
3586 first time that such client does not exist. This was done
3587 for example with private message. Affected file is
3588 lib/silcclient/client_prvmsg.c.
3590 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3592 * Do not add regex.h for WIN32. The affected file
3593 includes/silcincludes.h.
3595 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3596 not work yet 100%. It generates the DLL's automatically
3597 when compiling with --with-win32 under cygwin.
3599 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * lib/contrib/regex.c is not compiled on WIN32.
3603 * Added silc_net_get_socket_opt function to the
3604 lib/silcutil/silcnet.h.
3606 * Added includes/silcwin32.h for WIN32 specific includes
3609 * Do not use ptime structure or any of the posix process
3610 functions on WIN32 in lib/silccrypt/silrng.c.
3612 * Added silc_gettimeofday to provide generic function
3613 for struct timeval on all platforms. Added the function
3614 to lib/silcutil/silcutil.h.
3616 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3618 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3619 library as they clearly belong there. As a plus side we
3620 can make the actual socket connection routines platform
3623 Added also new generic function silc_socket_read and
3624 silc_socket_write (that used to be silc_packet_[read/write].
3625 The implementation of these are platform specific.
3627 * Added WIN32 specific routines of silc_socket_[read/write]
3628 to lib/silcutil/win32/silcwin32sockconn.c.
3630 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3632 * Added preliminary support for native WIN32 compilation under
3633 cygwin (using the -mno-cygwin option for GCC) to the
3634 ./configure.in.pre. The --with-win32 now prepares the
3635 compilation for native WIN32.
3637 * Rewrote the SILC Scheduler interface in the file
3638 lib/silcutil/silcschedule.h. The scheduler is now context
3639 based and does not have anymore any global static scheduler.
3640 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3641 and created lib/silcutil/win32 directory for WIN32 based
3644 * Added Unix specific network routines to the
3645 lib/silcutil/unix/silcunixnet.c and the old
3646 lib/silcutil/silcnet.c includes now only generic routines.
3648 Added WIN32 specific network routines to the
3649 lib/silcutil/win32/silcwin32net.c.
3651 * Added Unix specific utility functions from the
3652 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3654 * Added WIN32 SILC Scheduler to the file
3655 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3658 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3660 * Do not handle JOIN notify in the server if the target client
3661 is not registered (idata->registered == FALSE). The affected
3662 file is silcd/packet_receive.c.
3664 * Update the nickrec->founder in event_cumode in the Irssi SILC
3665 client. Affected file irssi/src/silc/core/silc-channels.c.
3667 * Fixed the CUMODE_CHANGE notify handling in the server when
3668 server and router are announcing their clients on channels.
3669 Now the mode changes are saved and notified correctly. The
3670 affected file is /silcd/packet_receive.c.
3672 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3673 They really did not replace the cache entry in the ID Cache.
3674 Now they do that. Affected file silcd/idlist.c.
3676 * Fixed the KICK notify handling in the Irssi SILC client to
3677 update the channel records so that the kicked client does not
3678 appear to be on the channel. The affected file is
3679 irssi/src/silc/core/silc-channels.c.
3681 * Always update the conn->current_channel when executing command
3682 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3684 * Fixed the KILL notify handling in Irssi SILC client to remove
3685 the killed client on all channels.
3687 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Fixed the silc_parse_command_line to remove extra spaces
3690 from the start and end of the arguments. Affected file is
3691 lib/silcutil/silcutil.c.
3693 * Cancel and free any active protocol in the function
3694 silc_server_close_connection. Affected file silcd/server.c.
3696 * Cancel and free any active protocol in the function
3697 silc_client_close_connction. Affected file is
3698 lib/silcclient/client.c.
3700 * Do not execute the KILL command for clients that are in
3701 history (ie. they are not in the network). Affected file is
3704 * Fixed KILL notify handling, client does not crash anymore.
3705 Affected file irssi/src/silc/core/silc-channels.c.
3707 * Reduced the default packet buffer size from 2048 to 1024 in
3708 lib/silccore/silcpacket.c.
3710 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3711 counter to the SKE context that is incresed when the SKE library
3712 performs async operation outside the library. If the outside
3713 process frees the SKE context and FREED status will be set
3714 and the library will detect after the sync operation that the
3715 libary is freed. The affected files are
3716 lib/silcske/silcske[_status].[ch].
3718 * Resolve the client entry information in the function
3719 silc_client_channel_message to assure that NULL pointer is not
3720 passed as client entry to the application. */
3722 * Fixed the task timeout calculation to assure that there is
3723 never negative timeouts. The affected file is
3724 lib/silcutil/silcschedule.c.
3726 * Fixed the channel user mode notification sending in server.
3727 It was sent point-to-point to the router (or to server by router)
3728 but it needs to be destined to a channel. The routines now
3729 supports sending the channel user mode notifys to the channels
3730 when announcing clients and channels. Affected files are
3731 silcd/server.c and silcd/packet_receive.c.
3733 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3734 It did not actually replace the old channel entry in the cache.
3735 Affected file lib/silcclient/client_notify.c.
3737 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Fixed a possible crash in silc_packet_send_prepare. It now
3740 assures always that there is enough space in the buffer and
3741 at the tail area of the buffer (for MAC).
3743 Fixed the inbound buffer reallocation in silc_packet_read.
3744 It was old code and did not handle the reallocation correctly.
3747 The affected file is lib/silccore/silcpacket.c.
3749 * Fixed buffer overflow in silc_parse_nickname in the file
3750 lib/silcutil/silcutil.c.
3752 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * make install generates new server keys only if there is not
3757 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3760 Added check that if the NOREPLY is set then we will not send
3761 the away message. This avoids infinite loop of away messages
3762 if both clients are away. The affected file is
3763 lib/silcclient/client_prvmsg.c.
3765 * Fixed client crash if /NICK was given without arguments.
3766 Affected file lib/silcclient/command.c.
3768 * Server does not send the invite list in INVITE command back
3769 to the client if the list was not altered. Added this notion
3770 to the protocol spec as well. Affected file silcd/command.c.
3772 Fixed possible crash in INVITE command by checking the
3773 value of silc_server_get_client_route command.
3775 * Fixed the INVITE notify type handling. The arguments are now
3776 taken in correct order and client does not crash. The affected
3777 file is irssi/src/silc/core/silc-channels.c.
3779 Removed the "Inviting xxx to channel" message from the
3780 client library away and let the application handle it.
3781 Affected file lib/silcclient/command.c. Added that message
3782 to Irssi SILC client's message formats.
3784 * Fixed CMODE command crash in client. It now checks the
3785 amount of arguments correctly and does not crash. The affected
3786 file is lib/silcclient/command.c.
3788 * Do not create new channel automatically in silc_channels_join
3789 but check whether the channel by that name already exists.
3790 Affected file irssi/silc/core/silc-channels.c.
3792 * Do not send the SERVER_SIGNOFF to router if the disconnected
3793 entity was the router. Affected file silcd/server.c.
3795 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3796 SILC client as it was missing from there.
3798 Added the handling of the KICK notify to the Irssi SILC client
3799 as it was missing. Added "you have been kicked" message to
3800 Irssi SILC client's message modules formats.
3802 Added the handing of the KILL notify to the Irssi SILC client
3803 as it was missing. Added the kill message module formats
3806 The affected file is irssi/src/silc/core/silc-channels.c.
3808 * The router did not save the channel mode the server announced.
3809 Affected file silcd/packet_receive.c.
3811 * Fixed a possible crash in INFO command in server. If the
3812 server did not provide the server info it crashed. Affected
3813 file silcd/command.c.
3815 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Fixed the GETKEY command in the server to check also the
3818 global list. Otherwise the GETKEY would not work correctly
3819 in normal SILC server. Affected file silcd/command.c.
3821 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Fixed GETKEY crash, it crashed if the command did not succseed.
3825 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3828 is now real and not just an macro interface to GMP.
3830 Removed the entire GMP from the source tree and imported new
3831 NSS MPI library instead. Reason for removing GMP is that it is
3832 extremely large and compiles extremely slow. The NSS MPI
3833 is only a few files and compiles in less than 10 seconds.
3834 The speed is also about the same as GMP. The MPI is imported
3835 to lib/silcmath/mpi.
3837 If the system has GMP installed we will still use the GMP.
3838 If it is not then the NSS MPI will be compiled.
3840 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Merged a long nickname (127 characters long) crash bugfix from
3843 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3845 * Merged a freed memory reference bugfix from Irssi CVS tree.
3846 Affected file irssi/src/core/commands.c.
3848 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Added the server's public key sving and verification to the
3851 server when performing the SKE. This was missing and the
3852 remote server's (or router's) public key was accepted without
3853 checking whether we have it previously or trust it at all.
3854 Affected file silcd/protocol.c.
3856 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Check in the silc_server_timeout_remote if protocol is active
3859 and make sure that the protocol's final callback is called so
3860 that all memory if freed. Affected file silcd/server.c.
3862 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * silc_server_whois_send_reply crashed the server if the nickname
3865 was 127 characters long. Affected file silcd/command.c.
3867 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Added sanity check to the silc_server_new_client. If the hostname
3870 is provided inside username then check that the provided hostname
3871 really is the same as the resolved one. If the hostname was not
3872 resolved then check it from the public key. Affected file is
3873 silcd/packet_receive.c.
3875 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3876 if the server disconnected us and the connection is not valid
3877 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3879 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3880 the library to the lib/silcutil/silcutil.[ch].
3882 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Close log file after open. Affected file
3885 lib/silcutil/silclog.c.
3887 * Check whether sock == NULL in silc_client_send_packet and return
3888 if it is. Affected file lib/silcclient/silcclient.c.
3890 * Check rec->entry == NULL in the Irssi SILC Client before
3891 sending the channel message. Affecte file is
3892 irssi/src/silc/core/silc-servers.c.
3894 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Merged a splitted window bugfix from Irssi CVS tree. The
3897 affected file is irssi/src/fe-text/textbuffer-view.c.
3899 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3900 It did not print nickname.
3902 * Improved the distributions system a bit.
3904 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3907 irssi/src/fe-text/gui-window.c.
3909 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3910 to in-active server. The affected file is
3911 irssi/src/silc/core/client_ops.c.
3913 * Resolve the client in USERS command reply if the entry does
3914 not have username resolved. The affected file is
3915 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3916 command to WHOIS command to really resolve stuff. The USERS
3917 is not used any more in any critical section so WHOIS can
3918 be used even though it might be slower than IDENTIFY.
3920 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3923 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Changed the protocol API a bit more consistent in the
3926 lib/silccore/silcprotocol.[ch].
3928 * Changed the following headers to ROBODoc format:
3930 lib/silccore/silcpayload.h
3931 lib/silccore/silcprotocol.h
3932 lib/silccore/silcsockconn.h
3934 All core library headers are now formatted.
3936 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Fixed a bug in Irssi SILC client; do not show that you are
3939 server/router operator if you really are not. Affected file is
3940 irssi/src/silc/core/client_ops.c.
3942 * Renamed silc_command_free_payload to silc_command_payload_free.
3943 Affected file lib/silccore/silccommand.h
3945 * Added silcmath.h to include the prototoypes of various routines
3946 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3949 * Changed the following headers to ROBODoc format:
3951 lib/silccore/silcchannel.h
3952 lib/silccore/silccommand.h
3953 lib/silccore/silcid.h
3954 lib/silccore/silcidcache.h
3955 lib/silccore/silcmode.h
3956 lib/silccore/silcnotify.h
3957 lib/silccore/silcpacket.h
3958 lib/silcmath/silcmath.h
3960 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Added checking to the server code not to start the server if
3963 ciphers and stuff are not configured properly. Affected files
3964 silcd/serverconfig.[h] and silcd/server.c.
3966 * Changed the layout of the header files of the public interfaces
3967 in the SILC libraries. The new layout supports ROBODoc
3968 documentation tool (and some others) so that it is easy to create
3969 a library reference manual. All the other headers and source
3970 code must still follow the CodingStyle document. Also source
3971 code must not include these ROBODoc stuffs, only the headers.
3972 Furthermore, all public interface headers must now be named
3973 by using `silc' prefix, example: silcapi.h, silccipher.h.
3974 Some files were renamed due to this. All the other headers
3975 must not be used as public interfaces. I will update the
3976 CodingStyle document later. Changed following headers, so far:
3978 lib/silcclient/silcapi.h
3979 lib/silccore/silcauth.h
3980 lib/silccore/silcprivate.h
3981 lib/silccrypt/silcdh.h
3983 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Removed silc_client_packet_send_flush from the client library
3988 as it is not needed. Affected file lib/silcclient/client.[ch].
3990 * Added printing of message of unresolved authentication method
3991 to the Irssi SILC client. Added it to the module formats.
3992 Removed the same message from the client library.
3994 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Added new distribution feature, DISTLABEL. Every distribution
3997 can define own preprocessor label that can be used in the
3998 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3999 file distributions, acconfig.h.pre and prepare.
4001 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Added Makefile.defines_int to include the actual definitions
4004 for Makefile.defines.in. Tested the new distribution system,
4005 created distributions and tested installation.
4007 * Added AWAY message printing to the Irssi SILC client. Added
4008 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4010 * Added SCONNECT command to call the SILC's CONNECT command.
4011 Cannot use CONNECT directly since Irssi uses that internally.
4012 Affected file irssi/src/silc/core/silc-servers.c.
4014 Added ACTION local command. It is same as ME command but takes
4015 the channel as mandatory argument.
4017 Rewrote some of the Irssi's help files to suite for SILC
4020 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Added Makefile.defines[.in] that should for now on be included
4023 in all Makefile.am file in the source tree. That file includes
4024 all common compilation definitions for SILC source tree.
4026 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Minor changes to the ./prepare script to change the package
4029 name according the distribution name to the configure.in.
4031 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Created new distribution system. Added file `distributions'
4034 that defines all the distributions that can be created out of
4035 the SILC source tree. The ./prepare script now reads that
4036 file to determine how to prepare the distributions. The
4037 first argument to the ./prepare is the name of the distribution
4038 and second is the version of the distribution. If given
4039 without arguments it creates the default (toolkit) distribution
4040 with the default version (defined in ./prepare).
4042 All Makefile.am files that are subject to the distributions
4043 are now named as Makefile.am.pre. These are ./Makefile.am
4044 and lib/Makefile.am. Others may be changed later.
4046 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added invite list, ban list, some key management and connection
4049 error message printing to module formats in the Irssi SILC client.
4051 * Added new silc_client_set_away_message to set the away message
4052 that is back to the person who sent private message. The
4053 affected file lib/silcclient/silcapi.h and the
4054 lib/silcclient/client_prvmsg.c.
4056 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Fixed the private message sending in the Irssi SILC client,
4059 added local command KEY to the Irssi SILC client.
4061 Added key management and key agreement message formats to the
4062 irssi/src/fe-common/silc/module-formats.[ch].
4064 Added USERS (alias WHO) printing, server/router operator
4065 indication and LIST command printing to the module formats.
4067 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Fixed channel joining notify handling, cumode notify handling
4070 from Irssi SILC client.
4072 * Added SILC specific module-formats to the Irssi SILC client so
4073 that SILC specific message hilighting, colors etc is possible.
4074 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4076 Added channel mode, channel user mode, actions, notices,
4077 whois and whowas printing to the the module-formats.c.
4079 * Fixed a bug in channel deletion in the server. The channel
4080 is not left to the cache even if the channel founder auth mode
4081 is set when there are no users anymore on the channel. Affected
4082 file silcd/server.c.
4084 * The silc_net_localhost now resolves the entire hostname including
4085 the domain name. Affected file lib/silcutil/silcnet.c.
4087 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Changed the ask_passphrase client operation to be ascynchronous.
4090 It has now a completion callback and a context that the
4091 application must call after it has got the passphrase from
4092 the user. Affected files lib/silcclient/silcapi.h,
4093 lib/silcclient/protocol.c, lib/silcclient/command.c and
4096 Added SilcAskPassphrase callback that the application calls
4097 to deliver the passphrase to the library.
4099 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4100 The public key verification and especially a certificate
4101 verification is asynchronous procedure.
4103 Added new SILC_SKE_STATUS_PENDING status to indicate the
4104 request is pending and a callback will be called to finalize
4107 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4108 indicate that remote end did not send its public key (or
4109 certificate), even though we require it. Added check for this
4110 condition in the SKE. This was a security bug, now fixed.
4112 Defined new SilcSKEVerifyCbCompletion callback that is called
4113 when the verification process is completed.
4115 The affected files lib/silcske/silcske_status.h and
4116 lib/silcske/silcske.[ch].
4118 * Changed the verify_public_key client operation to be async
4119 as well. Defined SilcVerifyPublicKey callback that is used to
4120 indicate the success of the public key verification process.
4122 Changed the server and client to use the new async client
4125 * Changed the Irssi SILC client's internal scheduler to be called
4126 twice as many times as it used to be. As a result the client
4127 should be a bit faster now. Affected file is
4128 irssi/src/silc/core/silc-core.c.
4130 * Added support to Irssi SILC client of asynchronous public key
4131 verification and passphrase inquiry. Affected file is
4132 irssi/src/silc/core/silc-core.c.
4134 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Do not say "You have left channel %s" in client library.
4137 Moved it to the application. Affected files are
4138 lib/silcclient/command.c and silc/client_ops.c.
4140 * Fixed silc_client_get_clients. Command context was not
4141 duplicated and was freed memory in the callback. Affected
4142 file lib/silcclient/idlist.c.
4144 * Do not say "you are now talking..." on JOIN command in the
4145 client library. The appliation must handle it.
4147 * Do not say ".. changed topic to" in command reply in the
4148 client libary. The application must handle it.
4150 * Fixed TOPIC command sending in the client library.
4152 * Fixed a memory leak in silc_client_command_free in the file
4153 lib/silcclient/command.c.
4155 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Imported a modified version of Irssi client to the source tree.
4158 The Irssi will be used to create a new client called
4159 Irssi SILC. Imported to irssi/.
4161 Added silc_core_init_finish function to the Irssi. Affected
4162 file irssi/configure.in.
4164 A lot changes in the Makefile.ams around the irssi tree.
4166 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Do not rehash if the new size is same as the old size of the
4169 hash table, in the silc_hash_table_rehash*. The affected file
4170 lib/silcutil/silchashtable.c.
4172 * Replaced hash_table_del_by_context calls from the server
4173 (when channel->user_list and client->channels) to the
4174 hash_table_del as it is sufficient and faster.
4176 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Added silc_hash_table_list, silc_hash_table_get and the
4179 SilcHashTableList structure to provide an alternative way to
4180 traverse the hash table. The affected files are
4181 lib/silcutil/silchashtable.[ch].
4183 * Changed the server's idlist routines to use the hash table
4184 routines to optimize the code.
4186 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Replaced the client entry's `channel' list and channel entry's
4189 `user_list' list to hash tables for optimized lookup. Changed
4190 the code to use the hash table interface around the code.
4191 Affected file lib/silcd/idlist.[ch].
4193 * Added `auto_rehash' boolean argument to the function
4194 silc_hash_table_alloc to indicate whether the hash table should
4195 auto-rehash when it thinks is appropriate time. It will
4196 increase the hash table size if the there is twice as much
4197 entries in the table than the size of the table, and will
4198 decrease the size if there are twice as less entries than
4199 the size of the table.
4201 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4205 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * silc_idcache_purge_by_context deletes the entry now by context
4208 as it is supposed to do. Affected file lib/silccore/idcache.c.
4210 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4211 client is not anymore valid (WHOWAS givens the info) and not
4212 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4214 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Removed the `data' and `data_len' arguments from the ID Cache
4217 interfaces and added `name' argument. ID Cache does not handle
4218 anymore the binary data only a names associated with given ID.
4220 * When hashing a Client ID with silc_hash_id the entire ID is
4221 not hashed anymore, instead only the hash of the Client ID is
4222 hashed. This way we can access the Client ID from the cache
4223 with Client ID but with the hash of the ID (which is a hash of
4224 the nickname) as well without any difference in performance.
4226 Added also silc_idcache_find_by_id_one_ext to do one on one
4227 searching when we have the actual ID. Added also function
4228 silc_hash_client_id_compare. The affected files are
4229 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4231 * When hashing the name associated with a ID it is always done
4232 in lowercase. This way we can access the cache without worrying
4233 about case-sensitivity, even though, for example nicknames are
4236 * Fixed a bug in server with channel message sending. It put
4237 wrong ID type as destination ID. The affected file
4238 silcd/packet_send.c.
4240 * silc_idcache_del_by_context now deletes from all hash tables
4241 by context. Affected file lib/silccore/idcache.c.
4243 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Changed the client library to use the new ID Cache interface.
4246 Changes around the source tree.
4248 * Added silc_hash_table_rehash_ext to rehash with specific
4249 hash function. Affected file lib/silcutil/silchashtable.[ch].
4251 * Added silc_hash_string_compare to compare two strings in the
4252 hash table. Affected file lib/silcutil/silcutil.[ch].
4254 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added new function silc_idcache_del_by_context into the
4257 lib/silccore/idcache.[ch].
4259 * Changed the server's ID list routines to use the new ID Cache
4260 interface. Changes around the source tree.
4262 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Added silc_hash_table_del[_by_context]_ext functions in to the
4265 lib/silcutil/silchashtable.[ch].
4267 Removed silc_hash_table_find_all* routines and added new
4268 silc_hash_table_find_foreach to replace them.
4270 Added silc_hash_table_replace_ext function as extended
4271 replacing function. Separated the simple hash table interface
4272 from the extended hash table interface in the file
4273 lib/silcutil/silchashtable.h.
4275 * Fixed minor bugs and changed it to use some of the new
4276 hash table functions in lib/silccore/idcache.c
4278 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Added new function silc_hash_table_find_all to return all keys
4281 in the hash table by the specified key. As the hash table is
4282 collision resistant it also makes it possible to have several
4283 duplicate keys in the hash table. This function may be used to
4284 find all of the keys from the hash.
4286 Added user_context arguments to the SilcHashFunction,
4287 SilcHashCompare and SilcHashDestructor to deliver user specified
4290 Added new fuctions silc_hash_table_find[_all]_ext to do
4291 extended lookup with specified hash and compare functions and
4292 specified user contexts.
4294 Added new function silc_hash_table_add_ext to add the key
4295 with specified hash function and user context.
4297 Added new function silc_hash_table_foreach to traverse all
4298 entrys in the hash table. Added SilcHashForeach callback
4301 Added new function silc_hash_table_del_by_context to delete
4302 the entry only if the context associated with the key matches.
4304 Affected files are lib/silcutil/silchashtable.[ch].
4306 * Removed silc_hash_[server/client/channel]_id and added just
4307 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4308 silc_hash_id_compare to compare two ID's using as the hash table
4309 comparison function. Added also silc_hash_data to hash
4310 binary data and silc_hash_data_compare to compare it.
4312 * Removed silc_idlist_find_client_by_hash as it is not needed
4313 anymore. Affected file silcd/idlist.[ch].
4315 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4316 to use internally the SilcHashTable. The new ID Cache is a lot
4317 faster than the old one. Some of the ID Cache interface was also
4318 rewritten and obsolete and stupid functions were removed.
4320 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Added entry_count field to the SilcHashTable to keep the number
4323 of the entries in the table. Implemented the function
4324 silc_hash_table_rehash. Added new function
4325 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4327 Fixed a minor bug in silc_hash_table_free.
4329 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4330 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4331 into the lib/silcutil/silcutil.[ch].
4333 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Implemented a collision resistant hash table into the
4336 lib/silcutil/silchashtable[ch]. See the header and the source
4337 for the SilcHashTable API.
4339 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Merged dotconf version 1.0.2 into lib/dotconf.
4343 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Do not compile anything in lib/silcsim/* if the SIM support
4346 is not enabled. The tree should now compile without problems
4349 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Compiled the SILC under cygwin. Compiled and tested briefly
4352 without problems. More tests needed. The SIMs didn't compile
4355 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4357 * Fixed possible crash in silc_get_username in the
4358 lib/silcutil/silcutil.c.
4360 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Fixed a va_arg in silc/client_ops.c.
4364 * Oops, RC5 routines were named AES and caused some problems
4365 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4367 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Added new SilcIDIP structure into the lib/silccore/id.h and
4370 replaced the old `ip' fields from all SILC ID's to that type.
4371 This is a step towards IPv6 support.
4373 The silc_id_get_len takes now the ID as an extra argument.
4374 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4375 both IPv4 and IPv6 based ID's.
4377 The affected files are lib/silccore/id.[ch] and other files
4378 around the tree using these routines.
4380 * Removed the ID length arguments in server from various
4381 silc_server_send_notify_* routines -> they are not needed
4384 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Fixed memory leak in silc_encode_pem_file in the file
4387 lib/silcutil/silcutil.c.
4389 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Check minor version as well in the SKE. Affected files are
4392 silcd/protocol.c and lib/silcclient/protocol.c.
4394 * Added --identifier option to the server so that an identifier
4395 can be when creating the public key for the server. Affected
4396 file is silcd/silcd.c.
4398 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4399 lib/silccrypt/silcpkcs.c.
4401 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Register default ciphers and stuff when using -C option with
4404 the server. Affected file sildc/silcd.c.
4406 * Put back the servers public key filename format, it is better
4407 than the new one. For now, the client keys are saved with the
4408 new filename format. The affected file silc/client_ops.c.
4410 * Implemented the Cipher API for the rest of the ciphers that
4411 did not implement it or implemented it the wrong way.
4413 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Register default ciphers and stuff when using the -S option
4416 in the client. Affected file silc/silc.c. Same also when
4417 creating new key pair with -C option.
4419 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Fixed the silc_verify_public_key client operation function to
4422 save the public keys differently. The fingerprint is now
4423 used as filename and not the hostname. This way also the
4424 client keys are saved uniquely and not with hostnames. The
4425 affected file is silc/client_ops.c.
4427 * Trimmed the silc_hash_fingerprint function to remove extra
4428 whitespaces from the end of the fingerprint. The affected
4429 file is lib/silccrypt/silchash.c.
4433 * Added silc_cipher_register_default function to register all
4434 default ciphers. It can be used when configuration files
4435 does not exist and the application does not want any specific
4436 ciphers in any specific order.
4438 The SilcDList is now used as silc_cipher_list dynamically
4439 allocated cipher list. Removed the static list all together
4440 and now all ciphers must be allocated to the dynamic list.
4441 The silc_cipher_alloc routine was changed to check only the
4444 All silc_cipher_* routines that used to return int returns
4447 The affected files lib/silccrypt/silccrypt.[ch].
4449 * The same thing was done to silc_hash_* as for silc_cipher_*
4450 routines. Affected files lib/silccrypt/silchash.[ch].
4452 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4453 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4454 Added also silc_pkcs_[un]register[_default] functions.
4455 Removed the data_context from the PKCS API.
4457 * Added silc_hmac_register_default function to register default
4458 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4459 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4460 to unregister all hmacs at once.
4462 * Register the default ciphers, hash functions, PKCSs and HMACs
4463 if client's configuration file does not exist. The affected
4466 * The client did not load the hash functions from the SIM
4467 modules at all. Added support for this. Affected file is
4468 silc/clientconfig.c.
4470 * When decoding public key with silc_pkcs_public_key_decode, check
4471 the supported algorithm only if PKCS are registered. Affected
4472 file lib/silccrypt/silcpkcs.c. The same was done with the
4473 silc_pkcs_private_key_decode.
4475 * Fixed the SILC List routines to keep the list always in order.
4476 It used to change the list's order when traversing the list but
4477 not it preserves the order. Affected file lib/trq/silclist.h.
4479 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Added the client library to use the SilcSocketConnection's
4482 reference counter (by silc_socket_dup) to prevent the bug that
4483 the socket object may be freed underneath async operation.
4485 * The name resolv library checking fixes in the configure.in.pre.
4488 * Created new version of the protocol drafts for future
4489 development. The -03 drafts are the ones that will be changed
4490 in the trunk now and the -02 will remain as they are.
4492 * Send list of CUMODE notifys to the router when announcing
4493 the channel users to the router. Affected file silcd/server.c.
4494 If the router receiving channel founder CUMODE for a channel
4495 that already has channel founder it will send CUMODE notify
4496 to the sender to remove the channel founder rights from the
4497 announced client. Affected file silcd/packet_receive.c.
4499 * The CUMODE notify may now use Server ID as well as the entity
4500 who changes the mode. Updated protocool specs.
4502 * Updated INSTALL and README files.
4504 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * New web pages in the http://silc.pspt.fi. The pages was
4511 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Implemented the [DenyConnectin] config section in the server.
4514 Added silc_server_config_denied_conn to check whether incoming
4515 connection is denied. Affected file silcd/serverconfig.[ch].
4517 * Do not check the ports when checking the incoming configuration
4518 data if the port is 0, meaning any. Affected file is
4519 silcd/serverconfig.c.
4521 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Fixed buffer overflow in silc_string_compare in the file
4524 lib/silcutil/silcutil.c.
4526 * Fixed double free in silc_server_command_leave in the file
4529 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Fixed the version checking in the server. Affected file is
4534 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Fixed the configuration data fetching when accepting new
4537 connections in the server. Affected file silcd/server.c.
4539 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Added `sender_entry' argument to the function
4542 silc_server_packet_relay_to_channel so that we can check
4543 whether some destination actually belongs to the same route
4544 the sender belongs (ie, we must not resend the packet to the
4545 sender). Affected file silcd/packet_send.[ch].
4547 * Added `servername' field to the SilcClientEntry in the server
4548 to hold the name of the server where client is from. Affected
4549 file is silcd/idlist.h.
4551 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Moved the channel message encrypting in the router betwen
4554 router connections from silc_server_channel_message to the
4555 silc_server_packet_relay_to_channel since we want to check
4556 whether we have anybody channel before encrypting anything.
4557 Affected files silcd/packet_[receive/send].c.
4559 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Fixed the [AdminConnection] server config section to support
4562 multiple entries. Affected file silcd/serverconfig.c.
4564 * Added support into the server to check the validity of the
4565 incoming connection before executing any KE or authentication
4568 * The connection configuration is now saved to the KE and
4569 connection auth protocol contexts and not fetched anymore in
4570 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4572 * The local hosts listenning address and port is also resolved
4573 now when starting the server. We want to have the socket object
4574 to include the real address and port for the listener. Added
4575 new function silc_net_check_local_by_sock into the files
4576 lib/silcutil/silcnet.[ch].
4578 * Fixed a broadcast bug in server -> do not broadcast if we
4581 * Fixed a routing bug. Do not route broadcast packets ever.
4582 Broadcast packets must be processed always and not routed since
4583 they may be destined to some other host than yourself and thus
4584 would get routed without no good reason. Affected file is
4587 * Added function silc_server_config_is_primary_route to check
4588 whether primary router connection has been configured (a router
4589 configuration that we are initiating). If there is not, we
4590 will assume that there is only two routers in the SILC network
4591 and we will use the incoming router connection as our primary
4592 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4594 * Changed the order of the broadcasting. Broadcast _after_ the
4595 packet has been processed not before. Affected file is
4598 * Fixed a [ClientConnection] parsing bug. The port was never
4599 parsed correctly thus resulting to port 0. Affected file
4600 silcd/serverconfig.c.
4602 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4603 argument and did not set the broadcast packet flag. Affected
4604 file silcd/packet_send.c. Fixed same bug in the function
4605 silc_server_send_notify as well.
4607 * If we receive NEW_ID packet for our own ID in the server, ignore
4610 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Removed the nickname from the Private Message Payload.
4615 Updated the code and the protocol specs.
4617 * Updated protocol specs for submitting to the IETF.
4619 * Tweaked the Random Number Generator a bit. Affected file
4620 lib/silccrypt/silcrng.c. Exported a new function
4621 silc_rng_[global]_add_noise which can be used to add more
4624 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Do not parse packets with different timeout when protocol
4627 is active -> may cause problem with rekey. Affected file
4630 * When server receives signoff notify it must not create
4631 new channel key if the client is on any channels since the
4632 sender of the signoff notify will create it.
4634 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added printing of error messages during SKE protocol from the
4637 failure packet sent by server during SKE. Affected file
4640 * Removed the client's failure_callback handling with timeout
4641 and handle it immediately when received.
4643 * The SKE library returned wrong type in SUCCESS and FAILURE
4644 packets. They must be 32 bit MSB not 16 bit MSB.
4646 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Ok, rewrote the logic of the re-key and now it seems to work.
4649 I tested it on high traffic with frequent re-keys without
4650 problems. Added hmac_receive (and renamed hmac to hmac_send)
4651 in SilcClientConnection in lib/silcclient/client.h and
4652 in SilcIDListData in silcd/idlist.h. Also, removed the
4653 SilcPacketParserContext's cipher and hmac fields as they are
4654 not needed anymore and actually caused some problems when
4655 the ciphers and hmac's changed underneath the packet parser.
4657 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * If re-key protocol is active then process the incoming packets
4660 synchronously since we must assure that icoming packets encrypted
4661 with the old key is processed before the new keys is set to
4662 use. This is true other packets than for REKEY packets.
4663 Affected file silcd/server.c. The same was done to client library
4664 as well, affected file lib/silcclient/client.c.
4666 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Fixed bug in client and server to accept the force send if
4669 the packet is send from silc_[server/client]_packet_process
4670 function. Otherwise the packets are never delivered, oops.
4672 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Disable force sending of packets when REKEY protocol is active.
4675 We must assure that no packet is sent directly when rekey is
4676 performed. All packets must be sent through packet queue.
4677 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4678 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4679 function is silc_[server/client]_packet_send_real to check
4682 * Replaced the SIM paths from example config files to
4683 /usr/local/modules. Also, make install creates now
4684 /usr/local/silc/logs directory to hold all the SILC server
4687 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Made the configure.in.pre work on Solaris. Patch by salo.
4691 * Made all ciphers compatible with non-x86 machines. Defined
4692 CBC mode macros into lib/silccrypt/ciphers_def.h.
4694 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Fixed the make install.
4698 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * When MAC computation fails the silc_packet_decrypt returned 0
4701 even though it was supposed to return -1. Fixed this. The
4702 affected file is lib/silccore/silcpacket.c.
4704 * Do not replace the config files in /etc/silc (in make install)
4705 if they already exist. Affected file ./Makefile.am.
4707 * Do not send re-key packets immediately but through packet queue.
4708 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4710 * Changed silc_net_check_host_by_sock to return FALSE if the
4711 IP/DNS could not be resolved. Though, it returns the IP address
4712 now even if it could not resolve it (but returns also FALSE).
4713 Affected file lib/silcutil/silcnet.[ch].
4715 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Added silc_pkcs_decode_identifier to decode the public key's
4718 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4719 Added also silc_pkcs_free_identifier. Added also new context
4720 SilcPublicKeyIdentifier.
4722 * Added -S option to the silc client. It is used to dump the
4723 contents of the specified public key file.
4725 * Changed the PKCS api to return the public key length when
4726 setting the public key.
4728 * Fixed a fatal bug in the public and private key file loading.
4729 Affected file lib/silccrypt/silcpkcs.c.
4731 * Execute the packet parsing for client with zero (0) timeout
4732 if the protocol is active. Affected file silcd/server.c.
4734 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Made the key generation options to the silcd program. Added
4737 -C option, equivalent to client's option.
4739 * Added new [ServerKeys] config section to the server. It
4740 configures the server's public and private key.
4742 * Defined generic Public Key Payload into the protocol
4743 specification to send specific type of public keys and
4746 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4747 public key or certificate.
4749 * Implemented the GETKEY command to the server and to the

4758 * Added SilcServerRekey context into silcd/idlist.h.
4760 * Added the PFS support as defined in the specification to the
4761 SKE protocol. Affected files lib/silcske/*.c.
4763 * Added `ske_group' field to the SilcServerRekey context to hold
4764 the number of the SKE group that is used with PFS in re-key.
4765 Affected file silcd/idlist.h.
4767 * Added PFS re-key support to the server. Affected file is
4770 * Added silc_protocol_cancel to cancel execution of the next
4771 state of the protocol. Affected file is
4772 lib/silccore/silcprotocol.[ch].
4774 * Added the re-key support with and without PFS to the client
4775 library. Re-key is performed once in an hour, by default.
4777 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4778 Added silc_client_rekey_callback and silc_client_rekey_final.
4779 Affected files are lib/silcclient/protocol.[ch] and
4780 lib/silcclient/client.[ch].
4782 * Removed the `hmac_key' and `hmac_key_len' fields from the
4783 SilcClientConnection structure; not needed. Affected file is
4784 lib/silcclient/client.h.
4788 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Do not ask whether user wants to use the negotiated private key
4791 for private messages, just use it. Affected file is
4792 silc/local_command.c.
4794 * Added `send_enc_key' and `enc_key_len' fields to the
4795 SilcIDListData structure since they are needed in the re-key
4796 phase. Affected file is silcd/idlist.[ch].
4798 * Implemented the simple re-key protocol into the server.
4799 Affected files silcd/server.c and silcd/protocol.[ch]. The
4800 re-key will be performed once in an hour, by default.
4802 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4803 Added silc_server_rekey, silc_server_rekey_callback and
4804 silc_server_rekey_final.
4806 * Removed Tunneled flag from the protocol. Updated the code
4807 and the specifications.
4809 * Adde `pfs' field to the SilcIDListData to indicate whether
4810 the PFS is to be performed in the re-key. Affected file is
4813 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4816 int64 of at least the xintXX size. If void * is less that 4
4817 bytes uint32 * will be used. Defined bool as boolean.
4819 * Changed _ALL_ unsigned long and unsigned int to uint32,
4820 unsgined short to uint16 in the source tree.
4822 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4823 not handle clients that has entry->data.registered == FALSE.
4824 They are not in the network anymore. Affected file is
4827 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Implemented the sending of the SERVER_SIGNOFF notify in the
4830 server. Affected file is silcd/server.c.
4832 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4833 Added also silc_notify_payload_encode_args into the
4834 lib/silccore/silcnotify.[ch].
4836 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4837 Affected file silcd/packet_receive.c.
4839 * Implemented the SERVER_SIGNOFF notify handling in the client
4840 library. Affected file lib/silcclient/client_notify.c. Also,
4841 implemnted the printing of the SERVER_SIGNOFF info to the
4842 application. Affected file silc/client_ops.c.
4844 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4845 if the deleting was successful. Affected file silcd/idlist.[ch].
4847 * Added support for public key authentication in the connection
4848 authentication protocol in the client library. Affected file
4849 lib/silcclient/protocol.c.
4851 * Changed the server's silc_idlist_get_clients_by_* interface
4852 to support already allocated array so that new entries may be
4853 added to pre-allocated array. Affected file silcd/idlist.[ch].
4854 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4855 and command replies.
4857 * All command reply functions in the server now calls the
4858 pending command callback even if error occured. This way the
4859 error will be delivered to the client as well. Affected files
4860 silcd/command.c and silcd/command_reply.c.
4862 * Fixed INFO command to return local server's info if no server
4863 was provided. Affected file lib/silcclient/command.c.
4865 * Removed RESTART command for good. Updated the code and the
4868 * Rewrote parts of the task system. It is a bit simpler now.
4869 Removed unsued task priorities. The affected files are
4870 lib/silcutil/silctask.[ch].
4872 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Moved the USERS printing from the library to the application.
4875 Affected files lib/silcclient/command.c and silc/client_ops.c.
4877 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Added channel key re-key support. The re-key is perfomed
4882 only by the router and is done once in an hour. Added `rekey'
4883 field to the SilcChannelEntry in the server. Affected files
4884 silcd/server.c and silcd/idlist.h.
4886 * Added silc_task_unregister_by_context into the file
4887 lib/silcutil/silctask.[ch].
4889 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Added SILC_UMODE_GONE mode to indicate when the client is not
4892 present in the SILC network. Added also support to the local
4893 command AWAY that will set this mode. Added support of showing
4894 "xxx is gone" in WHOIS command. The USERS command shows the
4895 gone status as well.
4897 * Fixed setting server and router operator privileges in the
4898 server's UMODE command. Affected file silcd/command.c.
4900 * Merged the SKE KE1 and KE2 payloads into one payload. The
4901 new KE payload is equivalent to the old KE2 payload.
4903 Cleaned up the SKE Start Payload parsing. It now uses the
4904 simple buffer unformatting to do the parsing. A lot faster
4907 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4908 to the SKE that is used to indicate whether both of the SKE
4909 parties should perform authentication. By default only the
4910 responder performs authentication. By setting this flag also
4911 the initiator must do authentication. By default it is unset
4912 since in normal SKE case, client to server connection, only
4913 the responder should do authentication. When doing SKE between
4914 two clients both should perform authentication. Updated the
4915 code and the protocol specs.
4917 * A little fix to IDENTIFY command in the server. Search the
4918 client first by hash not nickname. Affected file is
4921 * Fixed the silc_client_close_connection to support closing
4922 the client to client connections wihtout deleting too much
4923 data. Affected file lib/silcclient/client.c.
4925 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4926 are received if protocol used to be active but is not anymore
4927 the application would crash due to NULL pointer dereference.
4928 Affected files silcd/server.c and lib/silcclient/client.c.
4930 * Added `hash' field to the SilcClientConnection to include
4931 the hash function negotiated in the SKE protocol.
4933 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4934 to set the channel founder authentication data. A client can
4935 claim the founder rights later by providing the authentication
4936 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4937 This way the channel founder can regain the channel founder
4938 privileges even it is left the channel. This works only on
4939 local server and the client must be connected to the same
4940 server to be able to regain the founder rights. Updated the
4941 protocol specs accordingly.
4943 Added support to the CMODE command in the client to set the
4944 founder auth data. Read the README to see how to set it.
4946 Added support to the CUMODE command to claim the founder
4947 rights. Read the README to see how to do it.
4949 Added support for the founder authentication to the Channel
4950 Entry in the server. Affected file silcd/idlist.h.
4952 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4953 server's CMODE command. Affected file silcd/command.c.
4955 * Added the following new functions into lib/silccore/silcauth.[ch]:
4956 silc_auth_get_method and silc_auth_get_data.
4958 * The server now saves the remote hosts public key to the
4959 SilcIDListData pointer. Affected file silcd/protocol.c.
4961 * The normal server now does not remove the channel entry from
4962 the cache if the founder authentication data is set. It used
4963 to remove it if the founder was the last one on the channel on
4964 the server and left the channel. The auth data is saved and
4965 if the channel is re-joined later the old entry is used with
4966 the old auth data. Affected files silcd/command_reply.c and
4969 * Removed the `pkcs' field from the SilcIDListData structure
4970 in the server; it is not used. Affected file silcd/idlist.h.
4972 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Fixed packet processing on slow links. Partial packets were
4975 never re-processed because the incoming data buffer was cleared
4976 by the application. Application must not directly clear the
4977 sock->inbuf, the packet processing routines handle it. Fixed
4978 this in client library and in server.
4980 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Fixed the WHOIS and IDENTIFY send reply function to really
4983 check whether to send list or just one entry. Affected file
4986 * Cleaned up the LEAVE command's channel key distribution. The
4987 affected file silcd/command.c.
4989 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4990 can enforce the channel mode as well. In that case the ID
4991 includes the ID of the server. The code now enforces the
4992 mode change if the router have different mode than the server.
4994 * The notify client operation with CMODE_CHANGE notify can now
4995 return NULL client_entry pointer if the CMODE was not changed
4996 by client. Application must check for this.
4998 * Added <Server ID> argument to INFO command to support server
4999 info fetching by Server ID.
5001 * Added silc_server_announce_get_channel_users to get assembled
5002 packets of channel users of the specified channel. Affected
5003 file silcd/server.[ch].
5005 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5006 was freed underneath the ID Cache.
5008 * Re-announce clients when the server received CHANNEL_CHANGE
5009 notify from the router. Affected file silcd/packet_send.c.
5011 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5014 crashed since it did not handle the fact that there is no cipher
5015 called "3" and didn't check the error condition. Now fixed.
5017 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5018 flag. It can be used to send message requests.
5020 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Implemented the RESTART command in the client.
5024 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5025 notice type messages. Added notice printing to the user
5028 * The channel keys are not re-generated if the channel's mode
5029 is PRIVKEY, ie private key on the channel exists. Affected
5030 files silcd/server.c and silcd/command.c.
5032 * Fixed a little bug in channel message delivery when channel
5033 private keys are set in the server. Affected file is
5034 silcd/packet_send.c.
5036 * Changed the setting on channel->on_channel = TRUE from the
5037 silc_client_save_channel_key to the JOIN command reply. The
5038 key payload is not received if the private channel key is set.
5039 Affected file lib/silcclient/command_reply.c and the
5040 lib/silcclient/client_channel.c.
5042 * When the CMODE_CHANGE notify is sent and the channel private
5043 key mode is removed the channel key must be re-generated in
5044 other cells as well. Added this support for the router in the
5045 silcd/packet_receive.c.
5047 * Added new local command NOTICE to send notice message on
5048 channel. Affected file silc/local_command.[ch].
5050 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Added new local command ME to the client. It is used to send
5053 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5054 some action. Affected file silc/local_command.[ch].
5056 * Changed channel_message and private_message client operations
5057 to deliver the message flags to the application. Added also
5058 the `flags' arguments to the silc_client_send_channel_message
5059 and silc_client_send_private_message functions. Affected file
5062 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Redefined the Private Message Payload to support private message
5065 keys and to support the new private message flags. Updated
5066 the protocol specs. Flags makes it possible to have for example
5067 CTCP style messages.
5069 * Added new type SilcPrivateMessagePayload and defined an API
5070 for it in the lib/silcclient/silcprivate.[ch].
5072 * Tested private message private keys successfully. Tested the
5073 private message key set, unset and list commands with the new
5076 * Redefined the Channel Message Payload to include the channel
5077 message flags (equal with private message flags) to support
5078 for example CTCP style messages.
5080 * Defined some of the message (for channel and private message)
5081 flags. Updated the protocol specs and added the flags to the
5082 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5084 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Added SilcKeyAgreementStatus type to the key agreement routines
5087 to indicate the current status and error if one occured.
5088 The status types are defined in the lib/silcclient/silcapi.h.
5090 * Added new local command KEY that is used to set and unset private
5091 keys for channels, set and unset private keys for private messages
5092 with remote clients and to send key agreement requests and
5093 negotiate the key agreement protocol with remote client. The
5094 key agreement is supported only to negotiate private message keys,
5095 it currently cannot be used to negotiate private keys for channels,
5096 as it is not convenient for that purpose.
5098 * Fixed a minor pending callback setting bug in the function
5099 silc_client_get_client_by_id_resolve, now the function works.
5100 Affected file lib/silcclient/idlist.c.
5102 * Added function silc_net_get_local_port to get local bound
5103 port by socket. Added to lib/silcutil/silcnet.[ch].
5105 * Added `sockets' and `sockets_count' fields to the SilcClient
5106 object. They hold the sockets of the listenning sockets in
5107 the client. Listenning sockets may be for example the key
5108 agreement server. Affected file lib/silcclient/client.[ch].
5109 Added functions the silc_client_add_socket and the
5110 silc_client_del_socket. They are exported to the application
5113 * Added ~./silc/clientkeys to support other client's public keys.
5115 * Renamed verify_server_key client operation to verify_public_key
5116 and added one argument to indicate the type of the connection
5117 (server, client etc.).
5119 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Added silc_server_connection_auth_request to handle the
5122 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5123 silcd/packet_receive.[ch].
5125 * Added silc_server_send_connection_auth_request into the
5126 silcd/packet_send.c to send the connection auth request packet.
5128 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5131 * Fixed the public key authentication in responder side in the
5132 server. The `auth_data' pointer includes the SilcPublicKey
5133 not the path to the public key. Affected file silcd/protocol.c.
5135 * Implemented the public key authentication in the initiator side
5136 in the server. Affected file silcd/protocol.c.
5138 * Removed the [RedirectClient] config section from the server
5139 configuration. Is not needed and I don't want to implement it.
5141 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Cleaned up the CMODE command in the server. It now works
5144 correctly and supports all the modes defined in the protocol.
5145 Affected file is silcd/command.c.
5147 * Added `hmac_name' field to the SilcChannelEntry in the server
5148 to hold the default HMAC of the channel. It can be set when
5149 creating the channel (with JOIN command). Affected files
5152 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5153 type to indicate the change of the current cipher and hmac
5154 on the channel. Client can safely ignore the <cipher> argument
5155 (if it chooses to do so) since the CHANNEL_KEY packet will
5156 force the channel key change anyway. The <hmac> argument is
5157 important since the client is responsible of setting the new
5158 HMAC and the hmac key into use.
5160 * Fixed the CMODE command in the client library as well.
5162 * Tested CMODE command in router environment successfully.
5164 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Show the version of the remote client (or server) when connecting
5167 to the server. It is logged to the log file. Affected file
5168 is silcd/protocol.c.
5170 * Fixed the KILLED notify handling in the client library. The
5171 client must be removed from all channels when receiving the
5174 Also, do not remove the client entry when giving the KILL
5175 command but when the KILLED notify is received.
5177 * Removed silc_idlist_find_client_by_nickname from the server.
5178 Not needed anymore. Affected files silcd/idlist.[ch].
5180 * Implemented the CHANNEL_CHANGE notify type handling to the
5181 server. Affected file silcd/server.c.
5185 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5187 * Added silc_server_send_notify_invite to send the INVITE
5188 notify between routers.
5190 * Implemented the INVITE command correctly to the server.
5192 * Implemented the INVITE notify type handling in the server.
5194 * Implemented the INVITE command to the client library and on the
5197 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Added function silc_server_get_client_resolve to find the
5200 client entry by ID from all ID lists and then resolve it
5201 (using WHOIS) if it cannot be found. Affected file is
5204 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Implemented the BAN command to the client library.
5208 * The JOIN command in the server now checks the invite list
5211 * Changed the silc_command_reply_payload_encode_va and the
5212 silc_command_payload_encode_va to support that if argument is
5213 NULL it ignores and checks the next argument. Affected file
5214 lib/silccore/silccommand.c.
5216 * Added silc_server_send_notify_ban to send the BAN notify
5217 type between routers.
5219 * Chaned the silc_notify_payload_encode to support that if
5220 argument is NULL it ignores and checks the next argument.
5221 Affected file lib/silccore/silcnotify.c.
5223 * Tested ban lists in router environment successfully.
5225 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Implemented BAN command to the server, in silcd/command.[ch].
5229 * Removed the BAN and INVITE_LIST modes from the CMODE command
5232 * Added function silc_string_match to regex match two strings.
5233 Affected files lib/silcutil/silcutil.[ch].
5235 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Redefined parts of the SilcChannelEntry in the server to support
5238 the new ban and invite lists.
5240 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Redefined the INVITE command. The same command can be used to
5243 invite individuals to the channel but also to manage the invite
5244 list of the channel (to add to and remove from the invite list).
5245 Updated the protocol specs.
5247 * Added new command SILC_COMMAND_BAN that can be used to manage
5248 the ban list of the channel. Updated the protocol specs.
5250 * Removed the channel modes: the SILC_CMODE_BAN and the
5251 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5252 in the CMODE command. The equivalent features are now available
5253 using INVITE and BAN commands. Updated the protocol specs.
5255 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5256 in the network about change in the current ban list. The notify
5257 type is not used by the client.
5259 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5260 support the invite lists.
5262 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added new function silc_string_regexify that converts string
5265 including wildcard characters into regex string that can
5266 be used by the GNU regex library. Added into the file
5267 lib/silcutil/silcutil.[ch].
5269 Added silc_string_regex_combine to combine to regex strings
5270 into one so that they can be used as one regex string by
5271 the GNU regex library. Added into the file
5272 lib/silcutil/silcutil.[ch].
5274 Added silc_string_regex_match to match two strings. It returns
5275 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5277 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Imported GNU regex to the soruce tree into lib/contrib.
5280 Fixed some compiler warning from the regex.c.
5282 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Fixed MOTD command in the server to work in router environment.
5286 * Fixed the MOTD command in the client library to support
5287 the server argument in the command.
5289 * Added `nickname_len' argument to the silc_idlist_add_client
5290 in the server, as the `nickname' argument may be binary data
5293 * Added silc_idlist_get_channels to return all channels from
5296 * Implemented LIST command to the server. Affected file is
5299 * Implemented the LIST command to the client library and on the
5302 * Added [<user count>] argument to the LIST command reply.
5303 With private channels the user count is not shown.
5305 * Updated TODO and README.
5307 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * The client entry's data.registered must be TRUE even with
5310 global client entry on global client list. The data.registered
5311 is used to check whether the client is anymore in the network,
5312 for example with WHOWAS command so it must be valid.
5314 * Fixed the WHOWAS command in the server. It now actually works
5315 in router environment. Added function into silcd/command_reply.c
5316 silc_server_command_reply_whowas_save.
5318 * Added silc_idlist_purge function to the silcd/idlist.c
5319 to periodically purge the ID Cache.
5321 * Fixed INFO command in the server. It works now in router
5322 environment. Added <server name> argument to the INFO command
5323 reply. Updated the protocol specs.
5325 * Fixed minor bug in silc_idcache_purge to not purge if the
5326 expire value is zero.
5328 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5329 they were buggy because of the WHOWAS information.
5331 * Fixed local command MSG to handle the async resolving of
5332 the remote client properly. It used to fail the first MSG.
5333 Affected file silc/local_command.c.
5335 * Added `data_len' field to SilcIDCache context.
5337 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Update TODO. Todo in commands in the server.
5341 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5344 used by routers as broadcast packet to inform other routers
5345 about the changed user mode.
5347 Implemented the notify handling in the server. Affected file is
5348 silcd/packet_receive.c. Added the function
5349 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5351 * Added new generic Channel Payload and deprecated the New Channel
5352 Payload. The New Channel Payload is now the generic Channel
5355 * Added new argument `mode' to the silc_server_send_new_channel
5356 as it is required in the Channel Payload now.
5358 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5359 and created a new and real SilChannelPayload to represent the
5360 new generic Channel Payload. Implemented the encode/decode
5361 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5363 * Added silc_server_get_client_channel_list to return the list
5364 of channels the client has joined for WHOIS command reply.
5365 Affected file silcd/server.[ch].
5367 * Implemented the channel list sending in the WHOIS command reply
5368 in server and in the client.
5370 Implemented the channel list displaying on the user interface
5371 as well. Affected file silc/client_ops.c.
5373 * Added silc_channel_payload_parse_list to parse list of Channel
5374 Payloads. It returns SilcDList list of SilcChannelPayloads.
5375 Client for example can use this function to parse the list of
5376 channels it receives in the WHOIS command reply. The caller
5377 must free the list by calling silc_channel_payload_list_free.
5378 Affected files lib/silccore/silcchannel.[ch].
5380 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Added one new argument <user mode> to the WHOIS command reply
5383 to return the mode of the user in SILC. Updated the protocol
5386 Implemented it to the server and client.
5388 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Fixed the mode printing on the user interface on joining.
5391 Affected file silc/client_ops.c.
5393 * Implemented the UMODE command and user modes in general to the
5394 client library and to the user interface.
5396 * Implemented the UMODE command to the server.
5398 * The server now sends UNKNOWN_COMMAND error status if client sends
5399 unknown command. Affected file silcd/command.c.
5401 * All server commands now handle the command identifier the right
5402 way when sending the command reply to the client. The client can
5403 use to identify the command replies with the identifier.
5405 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added silc_server_get_client_route to resolve the route to
5408 the client indicated by the client ID. Affected file is
5411 * Added silc_server_relay_packet as general function to relay
5412 packet to arbitrary destination. This deprecates functions
5413 like _send_private_message_key, _relay_notify etc. Affected
5414 file is silcd/packet_send.[ch].
5416 Removed silc_server_send_key_agreement,
5417 silc_server_send_private_message_key and
5418 silc_server_packet_relay_notify functions from the file
5419 silcd/packet_send.[ch].
5423 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5424 server. Affected file silcd/packet_receive.[ch].
5426 * Implemented the KILL command to the client. Implemented the
5427 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5428 Affected files lib/silcclient/command[_reply].c and
5429 lib/silcclient/client_notify.c. Implemented the KILL notify
5430 printing in the user inteface.
5432 * Fixed a lot silc_parse_nick memory leaks from the client
5433 library in the file lib/silcclient/command.c.
5435 * Changed the silc_server_send_notify_on_channels's `sender'
5436 argument from SilcSocketConnection to SilcClientEntry to
5437 check the sender as entry and not as connection object and not
5438 to send to the client provided as argument. The affected file
5439 is silcd/packet_send.[ch].
5441 * The notify packets that are destined directly to the client used
5442 to not to be processed by the server. Now changed that and the
5443 server processes all notify packets. After relaying the packet
5444 to the client the notify packet is processed in the server.
5446 * The silc_server_free_client_data now checks whether there is
5447 pending outgoing traffic for the client and purges the data to
5448 the network before removing the client entry.
5450 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5453 an client is killed from the SILC Network. Updated the protocol
5456 Added new function silc_server_send_notify_killed to the
5457 silcd/packet_send.[ch].
5459 * Added function silc_server_packet_relay_notify to relay notify
5460 packets that are destined directly to a client. In this case
5461 the server does not process the notify packets but merely relays
5462 it to the client. Affected file silcd/packet_send.[ch].
5464 Added also silc_server_packet_process_relay_notify to check
5465 whereto relay the notify. Affected file is
5466 silcd/packet_receive.[ch].
5468 * Implemented the KILL command to the server.
5472 * Added the backup schema desgined last fall to the protocol
5473 specs for everyone to see. The specification is in the
5474 *-spec-xx.txt draft and the packet type definitions for the
5475 backup routers is in *-pp-xx.txt draft. Thusly, added also
5476 new packet type SILC_PACKET_CELL_ROUTERS.
5478 * A big security problem in the implementation discovered. The
5479 signoff of an client did not cause new channel key generation
5480 which it of course should've done. The channel keys must be
5481 always re-generated when client leaves (or signoffs) the channel.
5482 The silc_server_remove_from_channels funtion now handles
5483 the channel key re-generation.
5485 * Added `sender' argument to the silc_server_send_notify_on_channels
5486 to not to send the client provided as argument. Affected file
5487 silcd/packet_send.[ch].
5489 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * Implemented OPER and SILCOPER commands into the server and
5494 * Added silc_auth_verify and silc_auth_verify_data to verify
5495 the authentication directly from the authentication payload.
5496 It supports verifying both passphrase and public key based
5497 authentication. Affected file lib/silccore/silcauth.[ch].
5499 * Added `hash' field to the SilcIDListData structure. It is the
5500 hash negotiated in the SKE protocol. Affected file is
5503 * Slight redesigning of the SilcAuthPayload handling routines.
5504 Do not send SilcPKCS but SilcPublicKey as argument.
5506 * Implemented the public key authentication support to the
5507 serverconfig. The public key is loaded from the provided path
5508 and saved as authentication data to void * pointer. Thus,
5509 changed the unsigned char *auth_data to void *auth_data;
5511 * Fixed SHUTDOWN command to send the reply before the server
5512 is shutdown. :) Affected file silcd/command.c.
5514 * Fixed fatal bug in CONNECT command. The hostname was invalid
5515 memory and server crashed. Affected file silcd/command.c.
5517 * Fixed fatal bug in CLOSE command. The server_entry became
5518 invalid but was referenced later in the command. Affected file
5521 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Fixed fatal bug in failure packet handling. Server ignored
5524 the failure and thus crashed when it came.
5528 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5531 that the command may be executed only once in (about) 2 seconds.
5532 The old SILC_CF_LAG flag is same but allows command bursts up
5533 to five before limiting.
5535 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5536 server code. Various commands now includes the CF_LAG_STRICT
5537 flag to disallow any kind of miss-use of the command.
5539 * Fixed the silc_buffer_unformat to not to allocate any data
5540 if the length of the data is zero. It used to allocate the
5541 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5543 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Changed the format of AdminConnection configuration section
5546 in the server. Added username of the admin to the format.
5547 Affected files silcd/serverconfig.[ch].
5549 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5550 to return admin configuration data by host, username and/or
5553 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Implemented WHOWAS command to the server. Added the functions:
5557 silc_server_command_whowas_parse,
5558 silc_server_command_whowas_send_reply,
5559 silc_server_command_whowas_from_client and
5560 silc_server_command_whowas_from_server
5562 * Added <Client ID> argument to the WHOWAS command reply. Updated
5563 the protocol specs accordingly.
5565 * Implemented WHOWAS command and command_reply to the client
5568 Implemented the WHOWAS printing on the user interface.
5570 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Added new argument to the WHOWAS command reply, the real name.
5573 It is an optional argument. Updated the protocol specs.
5575 * Added SilcIDCacheDestructor callback that is registered when
5576 the SilcIDCache is allocated. The callback is called when
5577 an cache entry in the ID Cache expires, or is purged from the
5578 cache. Added into lib/silccore/idcache.[ch].
5580 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5581 to destruct the client entries when the cache entry expires.
5582 Other ID Cache's in server and in the client library ignores
5585 * If the ID Cache entry's `expire' field is zero then the entry
5586 never expires. Added boolean `expire' argument to the
5587 silc_idcache_add function in the lib/silccore/idcache.[ch].
5588 If it is TRUE the default expiry value is used.
5590 * Added silc_server_free_client_data_timeout that is registered
5591 when client disconnects. By default for 5 minutes we preserve
5592 the client entry for history - for WHOWAS command.
5594 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Added support to the server to enforce that commands are not
5597 executed more than once in 2 seconds. If server receives
5598 commands from client more frequently, timeout is registered
5599 to process the commands. Affected file silcd/command.c.
5600 Added new function silc_server_command_process_timeout.
5602 * Changed NICK_NOTIFY handling in client library to check that
5603 if the client's nickname was changed, so there is no need to
5604 resolve anything from the server.
5606 * Removed error printing from the WHOIS and IDENTIFY commands.
5607 If error occurs then it is ignored silently in the client library.
5608 The application, however, may map the received error to
5609 human readable error string. The application currently maps
5610 the NO_SUCH_NICKNAME error to string.
5612 * Made the command status message public to the application. Moved
5613 them from lib/silcclient/command_reply.c to
5614 lib/silcclient/command_reply.h. The application can map the
5615 received command status to the string with the
5616 silc_client_command_status_message function.
5618 * Added check to the server to check that client's ID is same
5619 as the Source ID in the packet the client sent. They must
5622 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Added dist-bzip hook to the Makefile.am to make bzip2
5625 compressed distributions.
5627 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Server now enforces the maximum length for the nickname and
5630 the channel as protocol specification dictates. 128 bytes for
5631 nickname and 256 bytes for channel name.
5633 * Moved the WHOIS printing to the application. The client libary
5634 does not print out the WHOIS information anymore, the application
5635 must do it. Renamed silc_client_command_reply_whois_print to
5636 the silc_client_command_reply_whois_save.
5638 The client's idle time is also sent to the application now, and
5639 the idle is shown on screen.
5641 * Added silc_client_command_reply_identify_save to save the
5642 received IDENTIFY entries.
5644 * Do not check for channel private keys in message sending and
5645 reception if the channel does not have the PRIVKEY mode set.
5646 Affected file lib/silclient/client_channel.c.
5648 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5651 just surfaced after chaning the JOIN procedure.
5653 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Added silc_client_get_clients_by_list to get client entries
5656 from Client ID list, that is returned for example by JOIN
5657 and USERS command replies. The application should use this
5658 function for example when JOIN command reply is received to
5659 resolve the clients already on the channel (library does not
5660 do that anymore as USERS command reply is not used in the JOIN
5661 procedure anymore). Affected files lib/silcclient/silcapi.h and
5662 lib/silcclient/idlist.c.
5664 * JOIN command reply and USERS command reply returns now SilcBuffer
5665 pointers instead of unsigned char pointers when returning
5666 the client list and mode list.
5668 * Added <Client ID> argument to the JOIN command reply, mainly
5669 for the server to identify for which client the command was
5670 originally sent. Updated protocol specs accordingly.
5672 * Added SilcDlist private_key pointer to the SilcChannelEntry
5673 in the client to support the channel private keys. Affected
5674 file is lib/silcclient/idlist.h.
5676 * Added SilcChannelPrivateKey argument to the function
5677 silc_client_send_channel_message so that application can choose
5678 to use specific private ke if it wants to. If it is not provided,
5679 the normal channel key is used, unless private keys are set.
5680 In this case the first (key that was added first) is used
5681 as the encryption key.
5683 * Implemented the support for channel private key handling.
5684 Implemented the following functions:
5686 silc_client_add_channel_private_key,
5687 silc_client_del_channel_private_keys,
5688 silc_client_del_channel_private_key,
5689 silc_client_list_channel_private_keys and
5690 silc_client_free_channel_private_keys
5692 Affected file lib/silcclient/client_channel.c.
5694 * Added the support for the private keys in the channel message
5695 sending and encryption and in the message reception and
5696 decryption. Affected funtions are
5697 silc_client_send_channel_message and silc_client_channel_message.
5699 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5701 * Added SKE's key verify callback to the client library's
5702 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5704 * Removed the statement that server (or router) must send USERS
5705 command reply when joining to the channel so that the client
5706 knows who are on the channel. Instead, the client list and
5707 client's mode list is now sent in the JOIN command reply to the
5708 client who joined channel. This is better solution.
5710 * Added function silc_server_get_users_on_channel and function
5711 silc_server_save_users_on_channel to the silcd/server.[ch].
5713 * Removed function silc_server_command_send_users from the
5716 * Do not show topic on the client library anymore. The topic is
5717 sent in the command reply notify to the application and the
5718 application must show the topic now.
5720 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Added client searching by nickname hash into the IDENTIFY and
5723 WHOIS commands in the server as they were clearly missing from
5724 them. Affected file is silcd/command.c.
5726 * Fixed a bug in private message receiving in the client library.
5727 The remote ID was freed and it wasn't supposed, now it is
5730 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Minor fix to the channel payload; allocate the data area, as it
5733 needs to be of specific length.
5735 * If the key agreement port is zero then the operating
5736 system will define the bound port. Affected files are
5737 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5739 * Added new function silc_channel_payload_decrypt into the file
5740 lib/silccore/silcchannel.[ch].
5742 * Moved the channel message etc, check from silc_packet_decrypt
5743 to applications. The library calls now a generic
5744 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5745 when the packet is either normal or special. This was done to
5746 allow more wide range of checking that was not allowed when
5747 the code was in library. Now applications can do virtually any
5748 checks to the packet and return to the library the decision how
5749 the packet should be processed. Affected files are
5750 lib/silccore/silcpacket.[ch].
5752 Added silc_server_packet_decrypt_check to the server and
5753 silc_client_packet_decrypt_check to the client library.
5755 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5756 to send with specified source and destination information.
5758 * Channel message delivery between routers was broken after the
5759 channel key distribution was fixed earlier. The channel key
5760 was used be to distributed to other routers as well which is not
5761 allowed by the protocol. Now this is fixed and channel keys
5762 really are cell specific and the channel message delivery between
5763 routers comply with the protocol specification.
5765 * Fixed various commands in server to check also the global list
5766 for the channel entry and not just the local list. The affected
5767 file silcd/command.c.
5769 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added assert()s to buffer formatting and unformatting routines
5772 to assert (if --enable-debug) when error occurs. Affected
5773 file: lib/silcutil/silcbuffmt.c.
5775 * Changed to auto-reconnect to check whether the remote host is
5776 router and register the re-connect timeout if it is. It used
5777 to check that whether we are normal server, but router must do
5778 auto-reconnect with another router as well. Affected file
5781 * Removed the [<key len>] option from CMODE command as the cipher
5782 name decides the key length, nowadays. See the defined ciphers
5783 from the protocol specification.
5785 * Added [<hmac>] option to the CMODE command to define the HMAC
5786 for the channel. Added SILC_CMODE_HMAC channel mode.
5788 * Added [<hmac>] option for the JOIN command so that user can
5789 select which HMAC is used to compute the MACs of the channel
5792 * Added Hmac field to the Channel Message Payload. The integrity
5793 of plaintext channel messages are now protected by computing
5794 MAC of the message and attaching the MAC to the payload. The
5795 MAC is encrypted. Now, it is clear that this causes some
5796 overhead to the size of the packet but rationale for this is that
5797 now the receiver can verify whether the channel message decrypted
5798 correctly and also when private keys are set for the channel the
5799 receiver can decrypt the packet with several keys and check from
5800 the MAC which key decrypted the message correctly.
5802 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5803 lib/silccrypt/silccipher.[ch].
5805 * Added silc_hash_len to return the digest length into the
5806 lib/silcrypt/silchash.[ch].
5808 * Rewrote parts of Silc Channel Payload interface in the
5809 lib/silccore/silcchannel.[ch]. The encode function now also
5810 encrypts the packet and parse function decrypts it.
5812 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Fixed a minor formatting bug in the SKE's key material processing.
5815 It actually might have processed the keys wrong way resulting
5818 * Redefined the mandatory HMAC algorithms and added new algorithms.
5819 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5820 and hmac-md5 truncated to 96 bits. The mandatory is now
5821 hmac-sha1-96. Rest are optional (including the one that used
5822 to be mandatory). Rationale for this is that the truncated HMAC
5823 length is sufficient from security point of view and can actually
5824 make the attack against the HMAC harder. Also, the truncated
5825 HMAC causes less overhead to the packets. See the RFC2104 for
5828 * Added new [hmac] configuration section. The SKE used to use
5829 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5830 is of course wrong. The official names that must be proposed in
5831 the SKE are the ones defined in the protocol specification
5832 (hmac-sha1-96 for example). The user can configure any hmac
5833 using any hash function configured in the [hash] section. At
5834 least, the mandatory must be configured.
5836 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5838 * Added HMAC list to the SKE proposal list. It has now both
5839 hash algorithm list and HMAC list. This makes the protocol
5840 incompatible with previous versions. The SKE now seems to work
5841 the way it is supposed to work, for the first time actually.
5843 * Defined plain Hash algorithms to the protocol specification.
5846 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Implemented support for key agreement packets into the server.
5849 Added functions silc_server_key_agreement and
5850 silc_server_send_key_agreement. Other than these functions,
5851 server has nothing to do with this packet.
5853 * Added support for private message key packets into the server.
5854 Added functions silc_server_private_message_key and
5855 silc_server_send_private_message_key.
5859 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5860 called in the protocol's final callback instead in the END
5861 protocol state. This makes a little more sense and in the same
5862 time in client we can use the same protocol routines for normal
5863 key exchange and to key agreement packet handling as well.
5865 * Added to both client's and server's KE protocol context the
5866 SilcSKEKeyMaterial pointer to save the key material. We will
5867 bring the key material to the protocol's final callback by doing
5868 this. The final callback must free the key material.
5870 * Added SKE's packet_send callback into client's KE protocol
5871 context so that the caller can choose what packet sending function
5872 is used. This way we can use different packet sending when
5873 doing normal SKE when doing key agreement packet handling (in
5874 the key agreement packet handling we do not want to encrypt
5877 * Implemented the responder side of the key agreement routines
5878 in the client. The client can now bind to specified port and
5879 accept incoming key negotiation. The key material is passed
5880 to the application after the protocol is over.
5882 * Implemented the processing of incoming Key Agreement packet
5883 in the client. Added function silc_client_key_agreement to
5886 * Implemented the intiator side of the key agreement routines
5887 in the client. The client can now initiate key agreement with
5888 another remote client. The key material is passed to the
5889 application after the protocol is over.
5891 * Created client_keyagr.c to include all the key agreement
5894 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5895 SILC_TASK_CALLBACK except that it is not static.
5897 * Created client_notify.c and moved the Notify packet handling
5898 from the client.[ch] into that file.
5900 * Created client_prvmsg.c and moved all private message and
5901 private message key routines from the client.[ch] into that file.
5903 * Create client_channel.c and moved all channel message and
5904 channel private key routines from the client.[ch] into that file.
5906 * Changed silc_client_get_client_by_id_resolve to resolve with
5907 WHOIS command instead of IDENTIFY command, in the file
5908 lib/silclient/idlist.c.
5910 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Implemented the SKE's responder side to the Client library.
5914 * When FAILURE is received to the protocol do not trust it
5915 blindly. Register a timeout to wait whether the remote closes
5916 the connection as it should do it, only after that process the
5917 actual failure. This was changed to both client and server.
5919 * Added client_internal.h to include some of the structures
5920 there instead of client.h in lib/silcclient/.
5922 * Added function silc_task_unregister_by_callback to unregister
5923 timeouts by the callback function.
5925 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Some "Incomplete WHOIS info" errors has been appearing on the
5928 log files. Took away the entry->userinfo check from WHOIS
5929 reply sending. The entry->userinfo is now " " if client did not
5930 provide one. I thought this was fixed earlier but something
5931 is wrong still. Let's see if the error still appears.
5933 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Fixed a minor bug in the login when the channel key is
5936 re-generated in the server. It used to generate the key in
5937 wrong order and thus caused problems in the channel traffic.
5939 * Fixed a minor bug in channel key distsribution after
5940 KICK command. The key was not sent to the router even though
5943 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Added silc_ske_process_key_material_data as generic routine
5946 to process any key material as the SILC protocol dictates. The
5947 function is used by the actual SKE library but can be used by
5948 applications as well. This relates to the private message keys
5949 and the channel private keys since they must be processed the
5950 same way the normal SILC session keys. The protocol dictates
5951 this. Affected files: lib/silcske/silcske.[ch].
5953 Added also silc_ske_free_key_material to free the
5954 SilcSKEKeyMaterial structure.
5956 * Defined silc_cipher_set_key function to set the key for
5957 cipher without using the object's method function. The affected
5958 files: lib/silccrypt/silccipher.[ch].
5960 * Implemented silc silc_client_add_private_message_key,
5961 silc_client_add_private_message_key_ske,
5962 silc_client_del_private_message_key,
5963 silc_client_list_private_message_keys and
5964 silc_client_free_private_message_keys functions in the
5967 Added functions silc_client_send_private_message_key to send
5968 the Private Message Key payload and silc_client_private_message_key
5969 to handle incoming Private Message Key payload.
5971 * Added Cipher field to the Private Message Key payload to set
5972 the cipher to be used. If ignored, the default cipher defined
5973 in the SILC protocol (aes-256-cbc) is used.
5975 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Removed lib/silcclient/ops.h file.
5979 Redefined parts of the SILC Client Library API. Created new
5980 file silcapi.h that deprecates the ops.h file and defines the
5981 published Client Library API. Defined also private message key
5982 API and channel private key API into the file.
5984 This is the file that the application must include from the
5985 SILC Client Library. Other files need not be included by
5986 the application anymore.
5988 * Added new key_agreement client operation callback and also
5989 defined the Key Agreement library API for the application.
5991 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5994 is used by clients to request key negotiation between another
5995 client in the SILC network. If the negotiation is started it
5996 is performed using the SKE protocol. The result of the
5997 negotiation, the secret key material, can be used for example
5998 as private message key.
6000 Implemented the Key Agreement payload into the files
6001 lib/silccore/silauth.[ch].
6003 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Redefined ciphers for the SILC protocol. Added some new ciphers
6006 and defined the key lengths for the algorithms. Changed the
6007 code accordingly. The default key length is now 256 bits.
6009 * Fixed SKE key distribution function silc_ske_process_key_material
6010 when the key length is more than 128 bits. The default key
6011 length in SILC is now 256 bits.
6013 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6014 to indicate unsupported algorithm.
6016 * Renamed rijndael.c to aes.c and all functions as well.
6018 * Fixed a long standing channel key setting bug in client library.
6019 Weird that it has never surfaced before.
6021 * Fixed bug in channel deletion. If the entire channel is removed
6022 then it must also delete the references of the channel entry
6023 from the client's channel list as the client's channel entry and
6024 the channel's client entry share same memory.
6026 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * Implemented CONNECT and SHUTDOWN commands in the client.
6030 * Implemented CLOSE command to the client.
6032 * Added the function silc_idlist_find_server_by_name into the
6033 files silcd/idlist.[ch].
6035 Added the function silc_idlist_find_server_by_conn into the
6036 files silcd/idlist.[ch].
6038 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * DIE command was renamed to SHUTDOWN. Updated the both code
6043 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6044 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6046 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6049 * Added function silc_server_create_connection function to create
6050 connection to remote router. My server implementation actually
6051 does not allow router to connect to normal server (it expects
6052 that normal server always initiates the connection to the router)
6053 so the CONNECT command is only good for connecting to another
6056 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6059 or some other client was kicked from the channel.
6061 Implemented the handling of the notify type to both client
6064 Implemented silc_server_send_notify_kicked to send the KICKED
6065 notify. It is used to send it to the server's primary router.
6067 * Implemented the KICK command into server and client.
6069 * Added `query' argument to the silc_idlist_get_client function
6070 to indicate whether to query the client from server or not if
6073 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6074 to indicate that the client is not channel founder.
6078 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Removed the rng context from SilcPacketContext structure and
6081 changed that the packet routine uses the Global RNG API.
6083 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added support for quit message that client can "leave" on the
6086 channel when it quits the SILC. It is ditributed inside the
6087 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6089 Added silc_server_free_client_data that will take the
6090 signoff message as argument.
6092 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6094 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Updated parts of the protocol specification to keep it up
6099 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6102 payloads in one packet.
6104 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6105 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6106 use now the new List flag.
6108 * Also deprecated the following packet types: REPLACE_ID,
6109 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6111 * Added list support for Notify packet in server.
6113 * Added silc_server_send_notify_channel_change to send the
6114 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6115 the silc_server_send_replace_id.
6117 * Added silc_server_send_notify_nick_change to send the
6118 NICK_CHANGE notify type. Deprecates the function
6119 silc_server_send_replace_id.
6121 * Added silc_server_send_notify_join to send the JOIN notify type.
6122 Deprecates the function silc_server_send_new_channel_user.
6124 * Added silc_server_send_notify_leave to send LEAVE notify type.
6125 Deprecates the function silc_server_send_remove_channel_user.
6127 * Added silc_server_send_notify_cmode and
6128 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6129 types. Deprecates the silc_server_send_set_mode function.
6131 * Added SERVER_SIGNOFF notify type to indicate that server has
6132 quit. This means that all clients on the channel from that
6133 server will drop. This can be also used when netsplit happens.
6135 Deprecated REMOVE_ID packet type since it is not needed anymore
6138 Added silc_server_send_notify_server_signoff to send the
6139 SERVER_SIGNOFF notify type. Deprecates the function
6140 silc_server_send_remove_id.
6142 Added also silc_server_send_notify_signoff to send the
6143 SIGNOFF notify type.
6145 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6146 SILC protocol from this day on. Changed the protocol
6147 specification as well.
6149 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6150 notify type. It is used between routers to notify about
6151 topic changes on a channel.
6153 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6156 * Partly updated the protocol specification to comply with the
6157 changes now made. It is still though a bit outdated.
6159 * The JOIN notify type now takes one extra argument <Channel ID>.
6160 The packet used to be destined to the channel but now the
6161 JOIN type may be sent as list thus it is impossible to
6162 destine it to any specific channel. By adding this argument
6163 it is again possible.
6165 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Added CREDITS file. The CHANGES and CREDITS file will appear
6168 in the distribution as well.
6170 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6173 types in the server's silcd/packet_receive.c.
6175 * Implemented CMODE and CUMODE to work in router environment.
6177 * Fixed minor encoding and decoding buglet from the
6178 lib/silccore/silcmode.c.
6180 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6183 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6185 * Changed all SilcConfigServer* and silc_config_server* to
6186 SilcServerConfig* and silc_server_config*, respectively.
6189 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * Associated the ID (client or server ID) to the Authentication
6192 Payload to avoid any possibility of forging. Updated the
6193 protocol specification and the code accordingly.
6195 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * The RSA key length is now save to the RsaKey context in the
6198 key generation process in lib/silccrypt/rsa.c. The key length
6199 is now used to figure out the maximum size of the block allowed
6200 to be encrypted/signed.
6202 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6203 is equivalent to the silc_mp_mp2bin but does not allocate any
6206 * Changed silc_mp_mp2bin API to take length argument. If it is
6207 non-zero then the buffer is allocated that large. If zero, then
6208 the size is approximated using silc_mp_sizeinbase, which however
6211 * Created Global RNG API which is global RNG that application can
6212 initialize. After initializing, any routine anywhere in the
6213 code (including library) can use RNG without allocating a new
6214 RNG object. This was done to allow this sort of use of the
6215 RNG in code that has no chance to allocate RNG object. All
6216 applications currently allocate this and many routines in the
6217 library use this. Affected file lib/silccrypt/silcrng.[ch].
6219 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6220 it to use the Global RNG API.
6222 * Defined Authentication Payload into protocol specification that
6223 is used during SILC session to authenticate entities. It is
6224 used for example by client to authenticate itself to the server
6225 to obtain server operator privileges.
6227 Implemented this payload into the lib/silccore/silcauth.[ch].
6228 Implemented also routines for public key based authentication
6229 as the new protocol specification dictates.
6231 Moved definitions of different authentication methods from
6232 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6234 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6235 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6236 silc_pkcs_verify_with_hash functions into the file
6237 lib/silccrypt/silcpkcs.[ch].
6239 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * The client entry's userinfo pointer must be always valid.
6242 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6243 will fail since it requires the userinfo. Now, the userinfo
6244 is allocated as "" if actual userinfo does not exist. Actually,
6245 it must exist and it is totally Ok to drop client connections
6246 that does not announce the userinfo. However, we will make
6247 this workaround for now.
6249 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6250 to return the remote port by socket.
6252 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6255 SILC_SERVER_PENDING_EXEC and added an new macro
6256 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6257 data or when error occurs while processing the pending command.
6259 Added new argument `destructor' into silc_server_command_pending
6260 and to the SilcServerCommandPending object. This destructor is
6261 now called after calling the pending callback or if error occurs
6262 immediately. If error occurs the actual pending callback won't
6263 be called at all - only the destructor. The destructor may be
6264 NULL if destructor is not needed.
6266 All this applies for client library code as well. Similar
6267 changes were made there as well for the pending commands.
6269 In the client, the application must now allocate the
6270 SilcClientCommandContext with the silc_client_command_alloc
6273 * Added reference counter to the SilcServerCommandContext. Added
6274 function silc_server_command_alloc and silc_server_command_dup
6277 Same type of functions added to the client library for the same
6280 * Removed the cmd_ident from IDListData away since it is now
6281 global for all connections. It is the command identifier used
6282 in command sending and with pending commands. The affected file
6285 * Added reference counter to the SilcSocketConnection objecet to
6286 indicate the usage count of the object. The object won't be
6287 freed untill the reference counter hits zero. Currently only
6288 server uses this, and client ignores it. The client must be
6289 set to use this too later. The affected files are
6290 lib/silccore/silcsockconn.[ch]. Added also the function
6291 silc_socket_dup to increase the reference counter.
6293 This was mainly added because it is possible that the socket
6294 is removed underneath of pending command or other async
6295 operation. Now it won't be free'd and proper DISCONNECTING
6296 flags, etc. can be set to avoid sending data to connection that
6297 is not valid anymore.
6299 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6300 the connection. After that it sets SILC_SET_DISCONNECTED.
6301 It is, however, possible that the socket data is not still freed.
6302 The silc_server_packet_process now checks that data is not
6303 read or written to connection that is DISCONNECTED. The socket
6304 get's freed when the reference counter hits zero.
6306 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Changed the client operation API: channel_message operation's
6309 `sender' is now the client entry of the sender, not the nickname
6310 and the `channel' is the channel entry, not the channel name.
6312 In the private_message operation the `sender' is now also the
6313 client entry of the sender not the nickname.
6315 Affected file is lib/silcclient/ops.h and all applications
6316 using the client operations.
6318 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6320 * Moved the calling of ops->connect() from connect_to_server_final
6321 into receive_new_id functin since that is the point when the
6322 client is actually allowed to send traffic to network. The
6323 affected file is lib/silcclient/client.c.
6325 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6328 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6329 (if needs broadcasting) instead of broadcasting the packets one
6330 by one which would make a burst in the network traffic.
6332 * Added `broadcast' argument to the functions in silcd/server.[ch]
6333 silc_server_create_new_channel[_with_id] to indicate whether
6334 to send New Channel packet to primary router.
6336 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Added new function into the silcd/server.[ch] files:
6339 silc_server_create_new_channel_with_id to create new channel with
6340 already existing Channel ID.
6342 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6343 lib/silccore/silcpacket.h. This packet is used t send list of
6344 Set Mode payloads inside one packet. Server uses this to set
6345 the modes for the channels and clients on those channels, that it
6346 announced to the router when it connected to it. The protocol
6347 specification has been updated accordingly.
6349 * The silc_server_new_channel did not handle the packet coming
6350 from normal server as it normally does not send that. However,
6351 when it announces its channels it does send it. Implemented
6352 the support for that.
6354 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6355 into the file lib/silccore/id.h.
6357 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Fixed memory leaks in the functions silc_idlist_del_client,
6360 silc_idlist_del_channel and silc_idlist_del_server in the file
6361 silcd/idlist.c. All of those leaked like a sieve.
6363 * Fixed some small memory leaks in the client's function
6364 silc_client_notify_by_server.
6366 * Added functions into silcd/server.c: silc_server_announce_clients,
6367 silc_server_announce_channels and silc_server_announce_server.
6368 These functions are used by normal and router server to announce
6369 to its primary router about clients, channels and servers (when
6370 router) that we own. This is done after we've connected to the
6373 These functions effectively implements the following packet types:
6374 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6375 and SILC_PACKET_NEW_ID_LIST.
6377 * Added new functions into the silcd/packet_receive.[ch]:
6378 silc_server_new_id_list, silc_server_new_channel_list and
6379 silc_server_new_channel_user_list to handle the incoming
6380 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6382 * Added support of changing Channel ID in the function
6383 silc_server_replace_id. If the server that announces a channel
6384 to the router already exists in the router (with same name but
6385 with different Channel ID), router is responsible to send
6386 Replace ID packet to the server and force the server to change
6387 the Channel ID to the one router has.
6389 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6390 client that the Channel ID has been changed by the router. The
6391 normal server sends this to the client. Client must start using
6392 the new Channel ID as the channel's ID.
6394 Implemented handling of this new type into lib/silcclient/client.c
6395 into the function silc_client_notify_by_server.
6397 * Added new function silc_idlist_replace_channel_id into the files
6398 silcd/idlist.[ch] to replace the Channel ID.
6400 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Call silc_server_command_identify_check always when processing
6403 the IDENTIFY command in silcd/command.c
6405 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6407 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6408 send keepalive packets. The packet can be sent by clients,
6409 servers and routers.
6411 Added function silc_socket_set_heartbeat into the file
6412 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6413 If not set, the heartbeat is not performed. The actual
6414 heartbeat is implemented in the low level socket connection
6415 library. However, application is responsible of actually
6418 Added silc_server_send_heartbeat to send the actual heartbeat
6419 packet into silcd/packet_send.[ch]. Server now performs
6420 keepalive with all connections.
6422 * Added silc_task_get_first function into lib/silcutil/silctask.c
6423 to return the timeout task with shortest timeout. There was a bug
6424 in task unregistration that caused problems. TODO has been
6425 updated to include that task system must be rewritten.
6427 * The client library will now resolve the client information when
6428 receiving JOIN notify from server for client that we know but
6429 have incomplete information.
6431 * Rewrote parts of silc_server_remove_from_channels and
6432 silc_server_remove_from_one_channel as they did not remove the
6433 channel in some circumstances even though they should've.
6435 * Encryption problem encountered in server:
6437 The LEAVE command used to send the Channel Key packet to the
6438 router immediately after generating it. However, the code
6439 had earlier sent Remove Channel user packet but not immediately,
6440 ie. it was put to queue. The order of packets in the router
6441 was that Channel Key packet was first and Remove Channel User
6442 packet was second, even though they were encrypted in the
6443 reverse order. For this reason, MAC check failed. Now, this
6444 is fixed by not sending the Channel Key packet immediately but
6445 putting it to queue. However, this is more fundamental problem:
6446 packets that are in queue should actually not be encrypted
6447 because packets that are sent immediately gets encrypted
6448 actually with wrong IV (and thus MAC check fails). So, packets
6449 that are in queue should be encrypted when they are sent to
6450 the wire and not when they put to the queue.
6452 However, the problem is that the current system has not been
6453 designed to work that way. Instead, the packet is encrypted
6454 as soon as possible and left to the queue. The queue is then
6455 just purged into wire. There won't be any fixes for this
6456 any time soon. So, the current semantic for packet sending
6459 o If you send packet to remote host and do not force the send
6460 (the packet will be in queue) then all subsequent packets to the
6461 same remote host must also be put to the queue. Only after the
6462 queue has been purged is it safe again to force the packet
6465 o If you send all packets immediately then it safe to send
6466 any of subsequent packets through the queue, however, after
6467 the first packet is put to queue then any subsequent packets
6468 must also be put to the queue.
6470 Follow these rules and everything works fine.
6472 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Added new function silc_server_remove_clients_by_server to
6475 remove all client entries from ID list when the server connection
6476 is lost. In this case it is also important to invalidate all
6477 client entires as they hold the invalid server entry. This
6478 fixes fatal bug when server has lost connection and will reconnect
6481 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Made some sanity checks to silc_server_daemonise like to check
6484 whether the requested user and group actually exists.
6486 * Added sanity check to SKE's silc_ske_responder_finish to check
6487 that the public and private key actually is valid.
6489 * Invalidate the client's nickname when receiving Replace ID
6490 packet and the Client ID is being replaced. This means that the
6491 server will query the nickname if someone needs it (client)
6494 * Sort the ID Cache in client library when the ID Cache data
6495 has changed (needs sorting).
6497 * Do not allow for SILC client to create several connections to
6498 several servers. The client does not support windows right now
6499 and generating multiple connections causes weird behaviour.
6501 Irssi-silc client does support windows and can handle several
6502 connections without problems, see: www.irssi.org and SILC plugin.
6504 * Fixed some places where client was added to the IDList. The
6505 rule of thumb is following (in order to get everything right):
6506 If the client is directly connected local client then the
6507 `connection' argument must be set and `router' argument must be
6508 NULL to silc_idlist_add_client function. If the client is not
6509 directly connected client then the `router' argument must
6510 bet set and the `connection' argument must be NULL to the
6511 silc_idlist_add_client function.
6513 * The funtion silc_server_packet_send_local_channel actually did
6514 not check whether the client was locally connected or not. It
6515 does that now. Fixed a bug related to LEAVE command.
6517 * Fixed Remove Channel User payload parsing bug in server's
6518 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6520 * The server's silc_server_save_channel_key now checks also the
6521 global ID list for the channel as it might not be in the local
6522 list. Fixed a bug related to LEAVE command.
6524 * Is this the end of the [<unknown>] buglet that has been lurking
6525 around for a long time? A little for loop fix in server's
6526 silc_server_command_whois_parse that is used by both IDENTIFY
6527 and WHOIS command. At least, this was a clear bug and a cause
6528 of one type of [<unknown>] buglet.
6530 * WHOIS and IDENTIFY commands call the function
6531 silc_server_command_[whois/identify]_check function even if
6532 we are not router server.
6534 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added --with-gmp configuration option. If set the GMP
6537 is always compiled in the SILC source tree. If not set then
6538 it is checked whether the system has the GMP3 installed. If
6539 it has then the GMP won't be compiled (the system's headers
6540 and library is used), if it doesn't have it then the GMP is
6541 compiled in the SILC source tree.
6543 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Changed RSA private exponent generation to what PKCS #1
6546 suggests. We try to find the smallest possible d by doing
6547 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6548 not security fix but optimization.
6550 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Added new config entry [Identity] to fork the server and run
6553 it as specific user and group. A patch from Bostik.
6555 * Imported Dotconf configuration library into lib/dotconf.
6556 This will be used to create the SILC configuration files later.
6557 It will appear in the distsribution after this commit.
6559 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * A big code auditing weekend happening. Auditing code for
6562 obvious mistakes, bugs and errors. Also, removing any code
6565 Removed files for being obsolete:
6567 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6568 inline in the file lib/silcutil/silcbuffer.h)
6570 o lib/silcutil/silcbufutil.c (the header has inline versions)
6572 Changed code to fix possible error conditions:
6574 o The buffer formatting routines now check that the destination
6575 buffer really has enough space to add the data. This applies for
6576 both buffer formatting and unformatting
6577 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6578 unformatting was changed to accomodate following rules:
6579 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6580 sent to the function while XXX_*STRING will not allocate or copy
6581 the data into the buffer. Instead it sets the pointer from the
6582 buffer into the pointer sent as argument (XXX_*STRING used to
6583 require that the pointer must be allocated already). This change
6584 makes this whole thing a bit more consistent and more optimized
6585 (note that the data returned in the unformatting with XXX_*STRING
6586 must not be freed now). The routines return now -1 on error.
6588 o Tried to find all code that use buffer_format and buffer_unformat
6589 and added return value checking to prevent formatting and
6590 especially unformatting errors and possible subsequent fatal
6593 o Changed ske->x and ske->KEY to mallocated pointers in
6594 lib/silcske/silcske.h. Fixed possible data and memory leak.
6596 o Added return value checking to all *_parse* functions. Fixed
6597 many memory leaks as well.
6599 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6600 so that buffer overflows would not happen. All code now also
6601 checks the return value as it can fail.
6603 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Added reconnection support to server if the normal server looses
6606 its connection to the router (for example if router is rebooted).
6607 The server performs normal reconnection strategy implemented
6608 to the server. Affected file silcd/server.c.
6610 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Added new packet type SILC_PACKET_SET_MODE that is used to
6613 distribute the information about changed modes (for clients,
6614 channels and clients channel modes) to all routers in the
6615 network. Updated the protocol specification accordingly.
6617 Added functions into silcd/packet_send.c and
6618 silcd/packet_receive.c: silc_server_send_set_mode,
6619 silc_server_set_mode.
6621 Added new files silcmode.[ch] into lib/silccore that implements
6622 the encoding and decoding of Set Mode Payload. Added new type
6623 SilcSetModePayload. Moved the definitions of different modes
6624 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6626 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Oops, a little mistake in server's connection authentication
6629 protocol. The protocol is not ended with FAILURE but with
6630 SUCCESS if the authentication is Ok. :) Affected file is
6633 * Implemented NICK_CHANGE notify handling in server in the file
6634 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6635 the local clients on the channel. After the changing nickname
6636 in router environment snhould work and the [<unknown>] nickname
6637 should appear no more.
6639 The silc_server_replace_id function that receives the Replace ID
6640 payload now sends the NICK_CHANGE notify type also in the file
6641 silcd/packet_receive.c
6643 * Changed WHOIS and IDENTIFY command to support the maximum amount
6644 of arguments defined in protocol specs (3328 arguments). This
6645 fixed a bug that caused problems when there were more than three
6648 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6650 * Added extra parameter, command identifier, to the
6651 silc_client_send_command so that explicit command identifier
6654 Changed that ID list routines uses specific command identifier
6655 when sending WHOIS/IDENTIFY requests to the server so that they
6656 can be identified when the reply comes back.
6658 Affected files lib/silcclient/command.[ch],
6659 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6661 * Added `sender' argument to silc_server_packet_send_to_channel
6662 to indicaet the sender who originally sent the packet to us
6663 that we are now re-sending. Ignored if NULL. Affected file
6664 silcd/packet_send.[ch].
6666 * Added some server statistics support in silcd/server_internal.h
6667 SilcServerStatistics structure and around the server code. Also
6668 send some nice statistics information when client is connecting
6671 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Fixed channel ID decoding in server's JOIN command reply in
6674 silcd/command_reply.c
6676 * Fixed braodcasting of replace ID payload to not to send it if
6677 we are standalone server in silcd/packet_receive.c.
6679 * Fixed all channel message sending routines to not to send
6680 packets to clients that has router set, since they are routed
6681 separately in the same function earlier. Affects file
6682 silcd/packet_send.c and all channel packet sending functions.
6684 * In USERS reply, res_argv[i] are not allocated, the table
6685 is allocated. Thus changed that free the table, not its
6688 * In server's whois_check and identify_check if the client is
6689 locally connected do not send any WHOIS commands - they are not
6692 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Fixed some minor bugs in client when sending WHOIS command. The
6695 arguments was in wrong order.
6697 * Removed statis function add_to_channel from server in
6698 silcd/command.c that was previously used with the joining but
6701 * Tested USERS command in router environment successfully with two
6702 routers, two servers and two clients.
6704 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6706 * Reorganized the USERS command and command reply in client library
6707 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6708 When the command is given by user we register a pending command
6709 callback that will reprocess the command after the reply has been
6710 received from the server. When reprocessing the packet we then
6711 display the information. Thus, the USERS information is displayed
6712 now in the command callback instead of in the command reply
6713 callback. The processing of the command is same as previously
6714 when server has sent the command reply in the JOINing process.
6716 * Added to USERS command in silcd/command_reply.c to join the client,
6717 we didn't use to know about, to the channel after we've created
6718 a client entry for it. Also, for clienet we did know already still
6719 check whether it is on the channel or not and add it if not.
6721 * Removed silc_server_command_join_notify as the function and its
6724 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Changed the client's pending command handling to the same as the
6727 server's pending command handling. It is also now possible to
6728 execute command reply functions from other command reply
6729 function as the function callbacks for commands and command
6730 replies are one and same. The pending commands are not static
6731 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6732 in client connection context. Thus, pending commands are server
6733 connection specific as it is convenient.
6735 Changed the function silc_client_command_pending and
6736 silc_client_command_pending_del and added new function
6737 silc_client_command_pending_check. Removed the
6738 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6741 * Added cmd_ident, current command identifier, to the client
6742 connection context in lib/silcclient/client.h to keep track on
6743 command identifiers used in command sending. Client's command reply
6744 function handling now supports the mandatory command identifiers.
6746 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6747 funtions in client to fully support pending command callbacks.
6749 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6750 as one of the arguments to the application in the command reply
6753 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6754 before first releasing SILC but came back. Now it is removed again
6755 and should come back nomore. The FORWARDED flag was used only
6756 by the JOINing procedure by forwarding the command packet to router.
6757 Now, the JOINing procedure has been changed to more generic (due
6758 to various router environment issues) and FORWARDED is not needed
6759 anymore for anything. The protocol specification is yet to be
6762 Now, removed silc_server_packet_forward from server and the flag
6763 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6765 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6767 * Renamed NAMES command to USERS command. The NAMES was named that
6768 due to historical reasons. Now it is renamed. Also, rewrote
6769 parts of the USERS command. The nickname list is not sent anymore
6770 by the server. Only Client ID and mode lists are sent in the USERS
6771 command. Changed this also to the protocol specification.
6773 The client now resolves the names and stuff after it receives
6774 the USERS list from the server when joining to the channel.
6776 * WHOIS and IDENTIFY commands has been changed to support multiple
6777 Client ID's per command. One can now search for multiple users
6778 in the network by sending only one WHOIS or IDENTIFY command.
6779 Changed the code and the protocol specifications.
6781 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6782 uses silc_server_command_whois_parse to parse the request. */
6784 * If normal server, do not parse the WHOIS and IDENTIFY requests
6785 before sending it to the router. Saves some time.
6787 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Fixed JOIN command on client library. Wrong number of arguments
6790 used to crash the client.
6792 * Added silc_server_channel_has_global function to check whether
6793 channel has global users or not.
6795 * Added silc_server_channel_has_local function to check whether channel
6796 has locally connected clients on the channel.
6798 * The silc_server_remove_from_one_channel now checks whether the
6799 channel has global users or not after given client was removed from
6800 the channel. It also checks whether the channel has local clients
6801 on the channel anymore. If it does not have then the channel entry
6802 is removed as it is not needed anymore.
6804 * The silc_server_notify now checks on JOIN notify whether the joining
6805 client is one of locally connected or global. If it is global then
6806 the channel has now global users on the channel and that is marked
6807 to the channel entry. Also, it now saves the global client to
6808 global list who is joining and JOINs it to the channel. This is
6809 for normal server, that is.
6811 Changed silc_server_send_notify_on_channel,
6812 silc_server_packet_relay_to_channel and
6813 silc_server_packet_send_to_channel check if we are normal server
6814 and client has router set (ie. global client) do not send the
6815 message to that client, as it is already routed to our router.
6817 * Implemented LEAVE notify type handling in silc_server_notify
6820 * Tested LEAVE command in router environment successfully. Tested
6821 with two routers, two servers and two clients.
6825 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6827 * Implemented SIGNOFF notify type handling in silc_server_notify
6830 * silc_server_remove_id now removes the client entry from all channels
6831 it has joined and thusly sends SIGNOFF notify type.
6833 * Rewrote the NAMES list generation in server by removing two excess
6834 loops. The lists are created now inside one loop.
6836 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * silc_server_remove_channel_user checks now also global list
6839 for channel and client.
6841 * silc_server_new_channel_user checks now both local and global
6842 list for channel and client. Fixed a bug in client id decoding.
6843 Used to decode wrong buffer.
6845 * silc_server_channel_message checks now both local and global
6846 list for channel entry.
6848 * Tested channel joining (hence JOIN) in router environment
6849 successfully. Tested with two routers, two servers and two
6852 * Tested channel message sending in router environment successfully.
6854 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Added silc_server_save_channel_key into server.[ch] to save the
6857 received channel key in Channel Key payload processing. It is
6858 also used in JOIN command reply handling.
6860 Equivalent function silc_client_save_channel_key added into
6861 client.[ch] into client library.
6863 * Changed JOIN command reply to send information whether the channel
6864 was created or not (is existing already) and the channel key
6865 payload. Changed protocol specs accordingly.
6867 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6868 the request was sent by ID and not by nickname. Crashed on
6871 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6874 now correctly save the received data.
6876 * silc_server_free_sock_user_data now notifies routers in the
6877 network about entities leaving the network.
6879 At the same time implemented functions silc_server_remove_id
6880 and silc_server_send_remove_id to receive and send REMOVE_ID
6881 packets. The packet is used to notify routers in the network
6882 about leaving entities. The ID removed will become invalid in
6885 * Added function silc_idlist_del_server into server. Removes and
6886 free's server entry from ID list.
6888 * silc_server_private_message function now checks, if we are router,
6889 that the destination ID really is valid ID, naturally.
6891 * In router when NEW_ID packet is received (for new client) the
6892 hash of the Client ID is saved in the ID Cache but the
6893 client->nickname is set to NULL, instead of putting the hash
6896 IDENTIFY command now also checks that client->nickname must be
6897 valid. If it is not if will request the data from the server who
6898 owns the client. Added new function
6899 silc_server_command_identify_check.
6901 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6902 to set the command to already allocated Command Payload.
6904 * Tested private message sending in router environment with two
6905 routers, two servers and two clients. Fixed minor bugs and now
6908 * Fixed segfault from client's NAMES command. Used to crash if
6911 * Forwarded packets must not be routed even if it is not destined
6912 to the receiver. Changed server code comply with this.
6914 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6916 * Added `require_reverse_mapping' boolean value to ServerParams
6917 structure. If TRUE (not default) the server will require that
6918 the connecting host has fully qualified domain name.
6920 If the reverse mapping is not required and hostname could not be
6921 found the IP address is used as hostname.
6923 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Implemented version string checking to both client and server.
6926 The check is incomplete currently due to the abnormal version
6927 strings used in development version of SILC.
6929 * Changed all command functions in server to use the new
6932 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Changed char *data to unsigned char *data in ID Cache system to
6935 support binary data as ID Cache data. Changed code to support
6936 binary data in lib/silccore/idcache.c.
6938 * Renamed silc_server_packet_relay_command_reply to
6939 silc_server_command_reply as it is normal packet receiving
6940 function. Rewrote the function to accept command replys for
6941 servers and not only for clients.
6943 * Mark remote router always as registered server if we are connecting
6944 to it. Otherwise, commands sent by the router to us are ignored.
6946 * All ID List find routines now returns the ID Cache Entry pointer
6947 as well if requested.
6949 * WHOIS command works now in router environment, tested with two
6950 routers, two servers and two clients.
6952 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6953 in router environment (as it is almost equivalent to WHOIS) but
6954 hasn't been tested thoroughly. Added new functions:
6956 silc_server_command_identify_parse
6957 silc_server_command_identify_send_reply
6958 silc_server_command_identify_from_client
6959 silc_server_command_identify_from_server
6961 * Disabled route cache adding because adding two different ID's with
6962 same IP replaces the old cache entry thus giving wrong route.
6963 The entry->router->connection is always the fastest route anyway
6964 so route cache may not be needed. Of course, new routes maybe
6965 established after receiving the ID when the entry->router->connection
6966 might not be anymore the most optimal.
6968 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6970 * Add route cache for received ID for fast routing.
6972 * Added silc_server_packet_route to route received packet on router
6973 that is not destined to us.
6975 * Renamed silc_server_get_route to silc_server_route_get.
6977 * Added id_string and id_string_len fields into SilcServer to
6978 include encoded ServerID for fast comparing without excess
6979 encoding of the ID's.
6981 * Cleaned up WHOIS command on server side. Added following static
6984 silc_server_command_whois_parse
6985 silc_server_command_whois_check
6986 silc_server_command_whois_send_reply
6987 silc_server_command_whois_from_client
6988 silc_server_command_whois_from_server
6990 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6991 arguments in command replies. All command functions should be
6992 updated to use this macro.
6994 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * Minor typo fixes on command reply handling on server.
6998 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7000 * Added silc_server_command_add_to_channel internal routine to add
7001 the client to the channel after router has created the channel and
7002 sent command reply to the server.
7004 * Added generic silc_server_send_command to send any command from
7007 * Use static buffer with ID rendering instead of duplicating data.
7009 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Fixed a channel user mode bug when joining to a channel server gave
7012 everybody channel founder rights, oops.
7014 * We mark ourselves as the router of the incoming server connection
7015 if we are router ourselves. This way we can check in some packet
7016 sending functions whether it is locally connected server. For
7017 incoming router connections we put NULL.
7019 * For router sending packets locally means now always sending the
7020 packet cell wide; to local clients and local servers. For normal
7021 server sending packet locally means sending it to only local
7024 * Fixed the JOIN command to really work in router environment. If the
7025 channel is created it is always created by the router. Router is
7026 also responsible of making the initial joining to the channel,
7027 sending JOIN notify to the sending server and distributing
7028 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7029 does not exist server doesn't do anything else but forward the
7030 command to the router which performs everything.
7032 * Added silc_server_send_channel_key function to send the Channel Key
7035 * Added silc_server_create_channel_key to create new channel key. The
7036 channel key is now re-generated everytime someone joins or leaves
7037 a channel, as protocol dictates. Note: channel->key_len is the
7040 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7043 packet_receive.[ch] to separate packet sending and receiving
7044 routines. The server.[ch] now includes everything else including
7045 actual packet processing (writing and reading data) and other
7048 Renamed silc_server_private_message_send_internal to
7049 silc_server_send_private_message. The routine is still though
7050 used only to relay private messages as server does not send
7051 private messages itself.
7053 Renamed silc_server_new_channel to silc_server_create_new_channel
7054 and added new function sicl_server_new_channel that handles the
7055 incoming New Channel packet. Added also new sending function
7056 silc_server_send_new_channel to send New Channel Payload.
7058 * Added new function silc_server_notify to process incoming notify
7059 packet to the server/router. Server may then relay the notify
7060 to clients if needed.
7062 * Added new function silc_server_new_channel_user to process incoming
7063 New Channel User packet. Router will redistribute the packet and
7064 send JOIN notify to its local clients and locally connected servers
7065 if needed. Normal server will send JOIN notify to its local client
7066 on same channel when received this packet. Added also corresponding
7067 sending function silc_server_send_new_channel_user to sent the
7070 * Added boolean route argument to send_notif_to_channel and
7071 packet_send_to_channel functions to attempt to route the packet
7072 if it is TRUE and send only locally if it is FALSE.
7074 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7076 * silc_server_replace_id now broadcasts the received replace ID
7077 packet if it is not broadcast packet already. The router must
7078 broadcast to inform other routers about changed ID.
7080 * Added backpointer to server's router into SilcServer context in
7081 silcd/server_internal.h.
7083 * Fixed silc_server_packet_broadcast to send correct broadcast
7086 * The channel key is now distributed to the local client as soon
7087 as it is received from the router (in router environment) so that
7088 no other packet may be sent for the channel until client has
7091 * silc_server_remove_channel_user now broadcasts the received
7092 Remove Channel User packet if it is not broadcast packet already.
7093 The router must broadcast to inform other routers about removed
7096 * Added users field into SilcPacketContext that is a reference count
7097 of the context. One can increase the reference count by calling
7098 silc_packet_context_dup which is now changed to just increase the
7099 reference count instead of duplicating the data. The reference
7100 count is decresed by calling silc_packet_context_free that will
7101 free the data after the reference count hits zero.
7103 For now on the packet context and everything allocated into it
7104 (including the raw packet from network) must be freed by calling
7105 the new silc_packet_context_free function. Added also new function
7106 silc_packet_context_alloc that must be used now to allocate the
7107 context. This also means that if a routine is asynchronous from
7108 silc_[client/server]_packet_parse_type the packet context must
7109 be duplicated by calling silc_packet_context_dup. Otherwise it
7110 gets free'd after silc_[client/server]_packet_parse_type returns.
7111 Also, one must remember that if packet is duplicated then its
7112 reference count must be decresed by calling the free function as
7113 many times as it was duplicated.
7115 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7116 from both client and server.
7118 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Made joining to a channel working in router environment.
7122 * Cleaned up JOIN command on server side and create function
7123 silc_server_command_join_channel internal routine to make the
7126 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Changed silc_command_pending list to SilcDList. Also, added
7129 `ident' field to SilcServerCommandPending structure to identify
7130 the reply and to call correct callback.
7132 Added silc_server_command_pending_check function to replace the
7133 corresnponding macro. The silc_command_pending list is not
7136 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7137 to set identifier to previously allocated Command Payload. It
7138 is used to set identifier for command when resending Command
7141 * Added silc_command_payload_encode_payload to encode Command
7142 Payload buffer from SilcCommandPayload structure.
7144 * Added silc_argument_payload_encode_payload to encode Argument
7145 payload buffer from SilcArgumentPayload structure.
7147 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7149 * Changed WHOIS command to support router connection on server side.
7150 The whois request is always sent to router unless the server is
7151 standalone server. After server has received the reply from the
7152 router will it send the reply to the client.
7154 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7155 broadcast received broadcast packet. The function is used only
7156 by router. The broadcast packet is always sent to the router's
7159 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7160 render given ID to printable string, for log files for example.
7162 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * Made basic router to router connections working. At least they
7165 can now connect to each other but nothing really works the way
7166 they are supposed - yet.
7168 * Added new initiator token to RouterConnection configuration
7169 file in silcd/serverconfig.[ch]. It is used to tell whether we
7170 are the initiator to the remote router or whether we'll expect
7171 the other end to connect.
7173 * Moved registering of listener task to silc_server_init, hence
7174 the server starts listenning as soon as it is run, even if it
7175 does not have connections to other routers. Let's see how well
7178 * Changed default connection retry timeouts for more suitable in
7181 * Removed cipher and such arguments from silc_idlist_add_client
7182 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7183 Added new function silc_idlist_add_data to add the keys and stuff
7186 * Added SilcIDListData structure and added it to SilcClientEntry
7187 and SilcServerEntry as their first field in the structure. This
7188 way we can explicitly cast the ID entries to the SilcIDListData
7189 structure and get common data for the entries. In past, we had
7190 to first check what type of connection it is and then cast it to
7191 correct ID entry type. Now, we can directly cast the opaque
7192 pointer to the SilcIDListData (no matter what ID entry it actually
7193 is) and get the data needed.
7195 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7198 in some circumstances even if threre were timeout tasks, though not
7199 IO tasks, but tasks anyway. Now fixed.
7201 * Defined SilcServerConnection structure to hold connection specific
7202 stuff about directly connected servers and routers. The definition
7203 is currently in silcd/server_internal.h. I thought about having
7204 a bit more important role fro this struct but for now it is used
7205 only when connecting to other server (or router actually).
7207 * Added connecting retry support in server when connecting to
7208 router(s). The retry feature implement exponential backoff
7209 algorithm. Also, added SilcServerParams structure to hold default
7210 parameters for server. For now, it include these retry settings
7211 and are hard coded. After server is moded to be as Silc Server
7212 Library this structure will be more important.
7214 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Changed client librarys channel->clients table to SilcList and
7217 changed code accordingly.
7219 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7221 * Changed client's channel table to SilcList and changed code
7222 accordingly. Also changed SilcChannelClientEntry to include back-
7223 pointer to the channel so that client entry can use that structure
7224 as list as well and we have fast cross-reference to the channel.
7225 This change dramatically decreased the complexity of channel
7226 handling with client entry and vice versa (removed one extra
7227 loop when searching for channel entry from many functions).
7229 * Changed server->sim from table to SilcDList and changed code
7232 * NAMES command can now be used from user interface. It will show
7233 the user list on the channel, neatly.
7235 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7236 Code now saves realname of the user if it becomes available.
7238 * Renamed configure.in to configure.in.pre and made ./prepare
7239 script to automatically add correct version string to
7240 configure.in which it creates from configure.in.pre.
7242 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * NAMES command reply now shows users mode with the nickname when
7247 * Moved silc_client_ch[u]mode[_char] functions from
7248 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7249 place sucks, they are utility functions and should be in some
7252 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7254 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7257 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Added TRQ (efficient deque and list library) into lib/trq. This is
7262 a very good list library that is currently used in the SILC. Defined
7263 SilcList API over the library because I didn't like the API very
7264 much. See lib/trq/silclist.h for the API and examples of how to
7265 use the API. Fixed various places in the code to use the new
7266 SilcList API. The SilcList is meant for lists that has a structure
7267 already defined as a list. It is not suitable to add just some
7268 context to the list (in TRQ, the context is the list actually).
7270 So, I defined SilcDList that can be used for the purpose where
7271 predefined list structure does not exit. This can be used as
7272 such list. Now some context just can be added to the SilcDList.
7273 Currently this list is not used in the SILC just yet, though there
7274 are a lot places where this can replace dynamically allocated
7275 tables and I will fix these places, later, to use SilcDList.
7276 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7277 and use TRQ internally).
7279 Also fixed some annoying warning messages that the original TRQ
7280 code generated. Also minor changes to TRQ's Makefile.in.
7282 * Added support for querying by Client ID to both WHOIS and
7283 IDENTIFY commands into server, as required by the protocol.
7285 * Removed method function pointers from SilcBuffer structure. They
7286 weren't used to anything and just increased the context size for
7287 no good reason. This change also made silc_buffer_alloc and
7288 silc_buffer_free functions inline functions.
7290 * Disabled command flooding detection support until it's fixed so
7291 that it accepts commands in but does not execute them more than once
7294 * Added silc_net_localhost(), to return local hostname, into
7295 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7296 that must be initialized before calling silc_client_init.
7298 * Added new function: silc_server_send_notify_on_channels to send
7299 notify messages to all channels client has joined. It is assured
7300 that the message is sent only once per client.
7302 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7303 lib/silcutil/silcutil.[ch] as silc_format function. The new
7304 function is generic and is used by server as well, not only by
7305 the logging routines.
7307 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7308 the provided version string was not acceptable. Added new function:
7309 silc_ske_check_version into lib/silcske/silcske.h. The function
7310 must be implemented by the application (client or server) and it
7311 does not reside in the SKE library. The function checks the version
7312 string remote end sent.
7314 * Added back pointers (to opaque context and to SilcSocketConnection)
7315 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7317 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7318 duplicate packet context structure.
7320 * Changed `notify' client operation to send same arguments as client
7321 receives from server except for ID's. ID's are mapped to correct
7322 ID entry and that is returned. Also, if channel entry is not sent
7323 by server but the notify is for channel the channel entry is sent
7324 to application (otherwise application doesn't know that it is for
7325 channel (library gets it from packet's Destination ID)).
7327 * Added silc_client_remove_from_channels into client library to
7328 remove a client from all channels it has joined to. Used when
7329 received SIGNOFF notify from server. Added also new function
7330 silc_client_replace_from_channels to replace old ID entry with
7331 new ID entry on all channels. Used when received NICK_CHANGE
7334 * Fixed ID Cache list handling in silc_idlist_get_client in
7335 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7336 to get (or query) client by ID.
7338 * Updated TODO list.
7340 * Added connection authentication status message defined by the
7341 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7342 support for these into the code in client and server side.
7344 * Added generic function silc_client_send_command to send any command
7345 with variable argument list. Application should use this function
7346 to send commands if the command functions provided by the library
7347 does not suite for the application's user interface needs.
7349 * Added new `failure' client operation. Application is notified about
7350 received failure packet if client is executing a protocol. In this
7351 case the protocol's execution has failed.
7353 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7354 is required by the protocol.
7356 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7357 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7360 * Added status flag to SilcSKE object to indicate realtime status
7361 of the SKE protocol.
7363 * Application receives now exactly same command reply arguments as
7364 the library receives from server. However, if ID is received the
7365 corresponding ID entry is returned to the application (eg. Client
7366 ID is mapped to correct SilcClientEntry entry and that is returned).
7367 Changed command_reply client operation due to this change.
7369 * Changed all ID's in commands and in command replys as ID Payloads.
7370 Change affected both client and server side codes.
7372 All ID's sent in SILC network (with execption of ID's in SILC
7373 Packet header) are sent in ID Payload to support variable length
7376 * Server now notifies nick changes and notifies all clients on
7377 the channels about the new nickname (about the new Client ID,
7380 * Implemented CMODE command to change channel modes. Supports all
7381 channel modes defined by the protocol specs except ban and invite
7382 lists. (Also, private channel key mode is supported but support for
7383 setting private channel key in client is missing, thus, this mode
7384 has no effect on client side (except that server requires that the
7385 client uses private channel key and normal channel traffic does not
7388 Also, invite mode works per se, but INVITE command does not work
7389 yet correctly, so you can set channel as invite only channel but
7390 inviting clients to the channel does not work (it is yet to be
7391 thought what's the best way to do it).
7393 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7394 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7395 Implemented CUMODE command to change user's mode on the channel.
7396 Supports all modes defined by the protocol specs.
7398 * Added NAMES command reply to return users modes on the channel.
7400 * Removed unnecessary and slow ciphers from lib/silccrypt.
7402 * Set SO_KEEPALIVE option to connection sockets by default.
7404 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7406 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7407 redefined the Notify Payload into protocol specs.
7409 * Added silc_id_payload_parse_id to get ID directly from raw
7412 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7415 accept searching by Client ID as well.
7417 * Added support for LEAVE and SIGNOFF notify types in client library.
7419 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7420 to parse ID Payload from raw data.
7422 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7424 * Added flags parameter into silc_ske_assemble_security_properties
7425 function in lib/silcske/silcske.[ch].
7427 * Changed notify client operation to fit better for notify messages
7428 sent by server. The notify payload received from server is now
7429 passed to the application (after parsing it to SilcNotifyPayload).
7430 It is application's responsibility to retrieve the arguments
7431 from the payload and show the message the way it wants. The message
7432 sent by server is implementation specific.
7434 * Changed public keys to comply with the protocol specification.
7435 Old public keys are not supported anymore and are not compatible.
7437 * Removed nickname from Channel Payload as the latest draft removed
7438 it. The client must resolve the nickname from the NAMES command
7439 reply received when it joined the channel.
7441 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7443 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Fixed some errors in protocol specification drafts.
7447 * Created lib/silccore/silcnotify.c to implement Notify Payload
7448 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7449 generic payloads described by protocol specifications. The file
7450 includes implementations for ID Payload and Argument Payload.
7452 * Changed Command Payload implementation to use the new Argument
7453 Payload. Changed command_xxxx_payload to command_payload_xxxx
7454 to comply with SILC coding conventions.
7456 * Added suppport for Argument Payload handling in Notify Payload
7457 implementation as protocol requires it. Added the new support
7458 into server and client lib as well.
7460 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7462 * Added support for multiple nicknames on same channel. [n] is
7463 added locally to the nickname if there are more than one same
7464 nicknames on the channel.
7466 * Server now sends all nicknames that matched WHOIS request.
7467 Client also shows the list received from server.
7469 * Added TOPIC command to client side. User can now set and show
7470 current topic on channel.
7472 * Added MOTD command to client and server. Also, server sends the
7473 motd when client connects to the server.
7475 * Changed version strings to comply ISO 8601.
7477 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Fixed protocol error handling in client library. It should now
7480 cope even if the SKE fails for some reason.
7482 * Made new protocol specification drafts for submitting to IETF.
7484 * Implemented TOPIC command to server in silcd/command.c.
7486 * Added two new notify types into lib/silccore/silcnotify.h:
7487 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7488 notify nickname change and topic setting/change on a channel.
7490 * API change of command_reply operation in client library. The
7491 application gets now the status type received from server as well.
7493 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7497 * Cras fixed and optimized the packet handling even further and
7498 it should work now. Minor change to the prototype of function
7499 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7501 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Added new function into lib/silcutil/silcschedule.[ch]:
7504 silc_schedule_with_fd to select() a specified fd. The function
7505 returns after timeout expires or data arrives or goes. The
7506 function is used by packet routines to wait that all data is
7507 received from network.
7509 * Fixed data reading from network in lib/silccore/silcpacket.c.
7510 The code now assures that all data is read from the fd and then
7511 continues packet processing. This was a bug fix since the code
7512 used to drop some data in some circumstances.
7514 * Added new function into lib/silcclient/client.[ch]:
7515 silc_client_start_key_exchange to start key exchange after
7516 connection has been established to server. The code internally
7517 now uses this funtion but its main purpose was to provide it
7518 for applications that perform their own connecting. After
7519 application has created a connection it merely calls this
7520 function to start the key exchange between client and server.
7521 The library takes care of everything else after that.
7523 Updated also lib/silcclient/README to explain the usage of
7526 * Do not send to application information that connection has
7527 been established. Application gets notified it by connect
7530 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7532 * Applied cras's patch to add silc_schedule_one function. The
7533 function runs scheduler once and returns.
7535 * Fixed the scheduler after cras messed it up. The timeout
7536 handling works now as it's supposed to work.
7538 * Added into lib/silccore/ silcnotify.h to include notify
7539 message types support. Changed silc_server_send_notify*
7540 functions, in server.[ch], to support those new notify types.
7541 Added the support for the notify types into client library,
7542 as well. Added new notify client operation into ops.h in
7545 * Changed silc_server_packet_send_to_channel to send normal
7546 packets instead of just channel message packets. The function
7547 is now used to send the notify packets to channels. It is not
7548 used to send channel message packets anymore, as server never
7551 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7552 va_arg()s as it seems to require it nowadays. I guess, if SILC
7553 is compiled with older va_arg() the new code should work anyway.
7555 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7557 * Splitted core library. Core library (lib/silccore) includes
7558 now only SILC protocol specific core (and common) components.
7559 Created new utility library (lib/silcutil) that includes more
7560 generic purpose stuff. The stuff for util library was taken
7561 from the old core library. This was minor and easy split.
7563 * Created SILC Client Library (lib/silcclient) that includes
7564 implementation of the SILC client without user interface. This
7565 was major move from silc/ directory. The code has been changed
7566 so that it is transparent towards the user interface. The
7567 silc/ directory includes now the same user interface as before
7568 and it uses the new client library. Read lib/silcclient/README.
7569 Basicly, the client library performs everything else related
7570 to SILC except user interface handling. Also, configuration
7571 files are considered to be part of user interface and library
7572 does not handle them.
7574 This change also changed a lot of structures, function naming etc.
7575 Most important change was that SilcClientWindow object was
7576 renamed to SilcClientConnection in the client library. Created
7577 also new file lib/silcclient/ops.h. Also added new files
7578 silc/local_command.[ch] and silc/client_ops.[ch].
7580 All these changes were made to make it easier for user interface
7581 designers to create what ever user interface for the SILC client
7584 It is also expected that the server will be moved to lib
7585 directory as well and SILC Server Library will be created;
7586 sometimes in the future.
7588 * Removed Local commands from lib/silccore/silccommand.h as
7589 they are application specific and new client library does not
7590 handle any of those anymore.
7592 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7593 old client implementation in silc/.
7595 * Added support for callback functions in SILC_LOG_* macros.
7596 Application can now set its own callbacks that will be called
7597 instead of using the default functions that will always print
7598 the debug messages to stderr (or stdout). Also, debugging can
7599 now be disabled by setting silc_debug to FALSE and re-enabled by
7600 setting it to TRUE. Note, that logging will still work even
7601 if debugging is disabled.
7603 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7604 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7605 silc_log_reset_debug_callbacks.
7607 * To enable debugging in silc client one must give now -d
7608 option on command line.
7610 * Changed silc_schedule_init to automatically allocate task queues
7611 if they are not allocated before calling it.
7613 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7615 * Added GMP 3.1 into math library.
7617 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7619 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7620 a channel in SILC network. The packet is used by servers and
7621 routers to notify other routers that user has left a channel.
7622 This little feature was missing until now. Added the feature
7623 to protocol specification as well.
7625 Added functions: silc_server_send_remove_channel_user and
7626 silc_server_remove_channel_user into server.[ch].
7628 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7629 lib/silccore/silcpacket.h. However, they are not implemented
7632 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Fixed joining to a channel and sending channel messages
7635 between server and router. The channel message sending should
7636 now work inside a cell.
7638 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Fixed the private message sending between server and router.
7641 The private message sending should now work inside a cell.
7643 * Added silc_server_replace_id into server.[ch] to replace
7644 existing ID in the SILC network.
7646 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7647 and silc_idlist_replace_server_id into idlist.[ch] in server.
7649 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7651 * Fixed the server to server connections. Server can again now
7652 connect to router. Router to router connections probably does
7655 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7657 * Added dynamic protocol registering support. Now protocols can
7658 registered and unregistered on the fly. Patch by cras.
7660 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7662 * Added lib/contrib directory to hold routines that some platforms
7663 don't have but are needed by SILC.
7665 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7666 into lin/contrib to provide getopt() and getopt_long() for
7667 those who don't have it.
7669 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7671 * Added AWAY command to client. When away message is set and
7672 client receives a private message packet the client automatically
7673 replies to the sender with the away message.
7675 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7676 bug seemed to be the cause of recent problems when compiling
7679 * Added version detection support to SKE protocol specification
7680 and added the new changes to the SKE implementation as well.
7681 There were other minor changes in the SKE protocol as well.
7683 Many changes in lib/silcske/silcske.[ch] and in
7684 lib/silcske/payload.[ch].
7686 * Added ^U functionality, clear input line. Patch from cras.
7688 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7690 * Mainly small bugfixes on core library. Fixed some debugging
7691 logging and buffer overflow in silclog.c.
7693 * Updated config.sub and config.guess on the distribution tree.
7695 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Added command lagging support in server. Client may execute
7698 commands now only once in two seconds.
7700 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7702 * Optimized packet reception. MAC computation and checking is now
7703 also more optimized. A lot previously duplicated code is now
7704 used as generic by both client and server.
7706 * Fixed key pair generation in clientutil.c
7708 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7710 * Added into lib/silccore/silcbufutil.[ch] new function;
7711 silc_buffer_realloc.
7713 * Moved generic packet sending/encryption functions to
7714 lib/silccore/silcpacket.[ch] from client and server. Some
7715 rewriting of the functions.
7717 * Moved all generic packet reception/decryption functions to
7718 lib/silccore/silcpacket.[ch] from client and server. The
7719 packet processing is now much cleaner in both client and server.
7720 These were major changes in both client and server.
7722 * Created many common functions in server to do packet sending.
7723 Previously code were duplicated a lot, this has been removed
7726 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7728 * Rewrote major parts of the ID cache system. Don't know
7729 whether it is better now or not but at least the API is more
7732 * Major rewrite on ID cache stuff on client because of the ID
7733 cache API changes. Added idlist.c to client.
7735 * Also major rewrite on ID cache stuff on server as well.
7736 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7737 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7738 in hand, instead they are all put into the ID cache system now.
7739 All server_idlist_* routines uses ID cache now instead of
7740 traversing its own lists (those lists does not exist anymore).
7741 SilcIDList though still exists. Also, SilcXXXEntry's are
7744 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7746 * Finally made the SKE implementation compliant to the protocol
7747 specification. All mp integers are now binary encoded as
7748 opposed being HEX encoded.
7750 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7753 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7754 functions: silc_[encode/decode]_pem. Also added function
7755 silc_encode_pem_file to PEM encode with newlines ('\n') for
7758 * SILC public keys are now encoded either PEM or binary. Same
7759 option is for private keys as well. By default private keys
7760 are binary encoded and public keys PEM encoded. Silly HEX
7761 encoding were removed.
7763 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7764 function to create fingerprints.
7766 * Fixed a bug in SHA1; does not change the original data anymore.
7768 * Partly implemented INFO command on client and server side.
7769 Fixed CLEAR command. Changes to SERVER command; show current
7770 server(s) when giving command without arguments. Added
7771 VERSION command to client.
7773 * Added check to server that unregistered connections cannot
7774 execute commands (unless it is specificly allowed).
7776 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Fixed screen refresh.
7780 * Fixed channel joining bug from client. On some circumstances
7781 client tried to join to a channel it had already joined.
7783 * Added public key verification process into client's protocol.c.
7784 The client now verifies the public key from user and saves
7785 it into ~./silc/serverkeys/ directory.
7787 Added into: clientutil.[ch]: silc_client_verify_server_key.
7789 * Changed SKE protocol's silc_ske_initiator_finish function
7790 to accept callback function that verifies the received public
7791 key. Removed old silc_ske_verify_public_key function.
7793 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7795 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7796 silc_pkcs_private_key[_data]_set.
7798 * Made the password and public authentication more cleaner in
7799 server's protocol.c.
7801 * Removed historic and obsolete protocol `channel_auth' from
7802 both client and server.
7804 * Removed wrong way of sending command status messages from
7805 server to client in server's command.c. The old way violated
7806 protocol specification.
7808 Changes to silccore/silccommand.[ch]: removed
7809 silc_command_encode_status_payload -> not needed anymore,
7810 changed silc_command_encode_payload_va to accept extra
7811 argument on variable argument list. The argument type must
7812 now be provided to the function. Also, added new function:
7813 silc_command_encode_reply_payload_va which is same as
7814 normal command_encode_payload_va except command status type
7815 is provided as extra argument.
7817 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7819 * Added ~./silc directory handling. The directory includes the
7820 public and private keys for the client.
7822 Added silc_client_check_silc_dir, silc_client_create_identifier
7823 and silc_client_load_keys.
7825 * Implemented SILC protocol compliant public key. Added public
7826 and private key saving to and loading from files.
7828 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7829 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7830 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7831 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7832 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7834 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7835 silc_pkcs_load_[public/private]_key.
7837 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7839 * Added silc_server_get_route (route.[ch]) to get connection
7840 data for the fastest route for given ID.
7842 * Implemented INVITE command on client and server. The command
7843 were re-defined in the SILC Protocol Specification and the
7844 implementation now complies with the specification.
7846 * Implemented PING command on client and server.
7848 * Implemented NAMES command on client and server. The server side
7849 supports currently only normal server not router server yet.
7850 Some changes to NAMES definition in SILC protocol specification.
7852 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7854 * Implemented LEAVE command on client and server.
7856 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7857 again. This change was made to the protocol as well. Server
7858 should not violate the protocol specification anymore.
7860 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7862 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7863 was tested. SOCKS4 was not but should work anyway.
