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

537 hash public keys and compare public keys in hash table. Affected
538 file lib/silcutil/silcutil.[ch].
540 * Added support for specifying multiple public keys for Client
541 connection section in server configuration file. This makes it
542 possible to accept multiple public keys from same host, or to
543 make a section that accepts any incoming host, and have the
544 accepted public keys listed in the section.
546 Added functions silc_sever_[find/get]_public_key, added the
547 support for this actually to all connection sections but only
548 the Client section is currently allowed to specify multiple

633 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
635 * Added `prefer_ipv6' argument to the functions
636 silc_net_gethostbyname[_async]. If it is TRUE it will return

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

717 client_entry->channels hash table everytime nick is changed.
718 Affected file lib/silcclient/client.c.
720 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
722 * ROBOdoc documented the lib/silcske/silcske.h, and improved
723 the SKE interface a bit.
725 * Fixed padding problem in PKCS#1. The padding was not actually
726 random since the random number generator was used incorrectly.
727 This security bug affects only when encrypting with PKCS#1, and
728 it is not currently used at all in SILC. SILC only use signing
729 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
731 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

797 * Added new configuration options and blocks:
798 keepalive_secs, reconnect_count, reconnect_interval,
799 reconnect_interval_max, reconnect_keep_trying and
800 require_reverser_lookup. Added ConnectionParam block, and
801 implemented the connection parameters when connecting as
802 initiator and when accepting connections as responder.

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

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

901 * Fixed the file transfer's key agreement payload to include
902 zero port also if the hostname is NULL because it could not
905 Call file transfer monitor callback now also if error occurs
906 during key agreement protocol.
908 Changed the silc_client_file_send interface to return the
909 SilcClientFileError instead of session id. The session ID
910 is returned into pointer provided as argument.
912 Check that the file exists locally before sending the
913 file transfer request at all.
915 Affected file lib/silcclient/client_ftp.c, silcapi.h.

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

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

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

1006 lists correctly. Affected file silcd/command.c.
1008 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1010 * When sending JOIN command to router for processing the
1011 sender's old command identifier was not saved back to the
1012 sender's command context, fixed now. The affected file is
1015 * Create the key in JOIN command of the router did not return
1016 the channel key, added check for this. Affected file is
1019 * Fixed a channel ID update bug in JOIN command reply. Do
1020 not directly upgrade the ID but call the function
1021 silc_idlist_replace_channel_id if the ID was changed.
1022 Affected file silcd/command_reply.c.
1024 * Fixed memory leaks from command calling if it would fail.
1025 Affected file silcd/command.c.

1052 functions. Affected file silcd/server.c.
1054 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1055 which ID was changed. This way the router will send the
1056 user list for the channel again, and server won't be in
1057 desync in some rare circumstances. Affected file is
1058 silcd/packet_receive.c.
1060 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1075 file for application programmers to quickly start using
1076 the SilcClientOperation functions in their application.
1077 Updated the lib/silcclient/README as well to tell about this
1078 nice file made available.
1080 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1082 * Call silc_server_remove_from_channels when removing client
1083 entry when NO_SUCH_CLIENT_ID was received. Affected file
1084 is silcd/command_reply.c.
1086 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1088 * Added server & router operator statistics updating. Affected
1089 file silcd/packet_receive.c and silcd/command.c.
1091 * Fixed the SERVER_SIGNOFF notify handling on normal server
1092 not to save the history information for clients. Same was
1093 fixed earlier in remove_clients_by_server function, but not
1094 here. Affected file silcd/packet_receive.c.
1096 * Raised the default connection-retry count from 4 to 7 in
1097 server. Affected file silcd/server.h.
1099 * Cancel any possible reconnect timeouts when we start the
1100 key exchange. Affected file silcd/server.c.
1102 * Do not reconnect on connection failure when SCONNECT was
1103 given. Affected files silcd/server.[ch].
1105 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1109 * Fixed the NICK command to always give the unformatted
1110 nickname to the one giving the NICK command. If unformatted
1111 nickname is cached already it will be formatted and the
1112 local entry will always get the unformatted nickname.
1113 Affected file lib/silcclient/idlist.c.
1115 * Fixed some double frees from client library commands.
1116 Affected file is lib/silcclient/command.c.
1118 * Fixed CUMODE command in server to assure that no one can
1119 change founder's mode than the founder itself, there was a
1120 little bug. Affected file silcd/command.c.
1122 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1124 * Removed the SilcClientCommandDestructor from the client
1125 libary, it is not needed anymore. Affected files are
1126 lib/silcclient/silcapi.h, command[_reply].[ch],
1127 client_notify, idlist.c.
1129 * Fixed GETKEY command to first resolve client, and then
1130 resolve the server only if the client was not found, instead
1131 of resolving both at the same time. Affected file is
1132 lib/silcclient/command.c.
1134 * Added silc_client_start_key_exchange_cb and lookup the
1135 remote hostname and IP address before starting the key
1136 exchange with server. The affected file is
1137 lib/silcclient/client.c.
1139 * The server's public key is now saved using the IP address
1140 of the server and not the servername for the filename.
1141 The hostname public key filename is checked as an fall back
1142 method if the IP address based filename is not found.
1144 Fixed the GETKEY command to save the fetched server key
1145 in correct filename.
1147 Print the remote server's hostname now when new key is
1148 received during connection process. Affected file is
1149 irssi/src/silc/core/client_ops.c.
1151 * Return always our own public key to the client if it asks
1152 for it with GETKEY command. Affected file silcd/command.c.
1154 * Removed the use_auto_addr variable from default config
1155 file since it was in wrong section. Affected file is
1158 * Fixed TOPIC_CHANGE notification to not route it when it
1159 was sent using silc_server_send_notify_to_channel function.
1160 Affected file silcd/command.c.
1162 * Fixed silc_server_send_notify_kicked to send the kicker's
1163 Client ID also, it was missing. Affected files are
1164 silcd/command.c, silcd/packet_send.[ch].
1166 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1168 * Do not save client history information in SERVER_SIGNOFF.
1169 Fixes the bug in normal server that it does not detect
1170 the client becoming valid after the server becomes back
1171 online. Affected file silcd/server_util.c.
1173 * Added `sock_error' field into the SilcSocketConnection
1174 context. When error occurs during socket operation (read
1175 or write) the error is saved. Added also new function
1176 silc_socket_get_error to return human readable socket error
1177 message. Affected files are lib/silcutil/silcsockconn.[ch],
1178 lib/silcutil/unix/silcunixsockconn.c, and
1179 lib/silcutil/win32/silcwin32sockconn.c.
1181 * The server now prints the socket error message in the
1182 signoff for client. Affected file silcd/server.c.
1184 * Fixed the `created' channel information sending from router
1185 to server in JOIN command. Checks now whether the channel
1186 really was created or not and set it according that.
1188 Fixed the JOIN command to use the client entry's current
1189 ID during the joining procedure instead of the one it sent
1190 in the command (it is checked though), since it can change
1191 between the packet processing and command processing, and
1192 would just case unnecessary pain in the client end. Affected
1193 file silcd/command.c.
1195 * Fixed a channel key payload sending to use correct channel
1196 ID when the server was forced to change the channel's ID by
1197 router. Router sent the key payload with the old Channel ID.
1198 Affected file silcd/packet_receive.c.
1200 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1202 * Call silc_server_save_channel_key only if the key payload
1203 was provided in the JOIN command's command reply. Affected
1204 file silcd/command_reply.c.
1206 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1208 * Fixed silc_mp_sizeinbase to return the value correctly with
1209 MPI. Affected file lib/silcmath/mp_mpi.c.
1211 * Fixed the stop_server signal to correctly stop the scheduler
1212 and gracefully stop the server when SIGTERM or SIGINT signals
1213 are received. Affected file silcd/silcd.c.
1215 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1217 * Simple handling of TERM and HUP signals. Also added some log
1218 flushing call around. Affected file is
1221 * Fixed small bugs in silclog.c. Now buffering output will take
1222 effect after 10 seconds since startup: This will ensure that
1223 no important startup messages are lost. Also output redirection
1224 will preserve original format ([Date] [Type] message).
1225 Affected file is lib/silcutil/silclog.c.
1227 * Added two options to the config file, in the logging section:
1228 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1229 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1231 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1233 * Do not print the warning about log files not being initialized
1234 more than once to avoid excess logging. Affected file is
1235 lib/silcutil/silclog.c.
1237 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1238 the SIM copying in make install in Makefile.am.pre.
1240 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1242 * Rewritten silclog APIs. Globally interesting changes follows:
1243 silc_log_set_files() changed to silc_log_set_file().
1244 silc_log_set_callbacks() changed to silc_log_set_callback().
1245 ROBOdoc documented silclog header file.
1246 SilcLogCb now returns bool to wether inihibit the default
1247 handler or not (to keep the old behaviour return always TRUE).
1248 The new APIs should also fix the problem of the
1249 silcd_error.log file that was written in the current directory.
1252 Log files streams will remain opened after silc_log_set_file()
1253 call, means less CPU usage notably on high traffic servers.
1254 File streams are now full buffered, and flushed to the disk
1255 every 5 minutes, lesses HD activity and CPU usage.
1256 Messages can be redirected, allowing admins to configure
1257 one single logfile for all server messages.
1258 the silc_log_quick global variable to activate fast-logging.
1259 Affected files lib/silcutil/silclog.[ch]
1261 * Changed some code to conform new silclog APIs. Affected
1262 files are doc/example_silcd.conf.in, silcd/server.c
1263 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1266 * Fixed a memory leak that could occur in some situations.
1267 Affected file silcd/serverconfig.c.
1269 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1271 * Added the silc_client_del_client to remove the client from
1272 all channels as well. Affected file lib/silcclient/idlist.c.
1274 * Fixed the client library to correctly remove the client
1275 from all channels when the client entry is being destroyed.
1276 Affected file lib/silcclient/client_notify.c, command.c.
1278 * Added auto-nicking support to the client library. If the
1279 applicatio now sets client->nickname it will be sent to the
1280 server after connecting by the library. This way for example
1281 SILCNICK (or IRCNICK) environment variables will have effect
1282 and always change the nickname automatically to whatever
1283 it is wanted. Affected file lib/silcclient/client.[ch].
1285 * Renamed silc_server_command_bad_chars to the
1286 silc_server_name_bad_chars and moved it to the
1287 silcd/server_util.[ch]. Added also new function
1288 silc_server_name_modify_bad to return nickname that
1289 includes bad characters as new nickname without those
1290 bad characters. This check and modify is now used in
1291 silc_server_new_client when the username is initially set
1292 as nickname, so it must be checked to be valid nickname.
1293 Affected file silcd/packet_receive.c.
1295 * The nickname length is now taken from the packet for real
1296 and not trusted to strlen() since it clearly can return
1297 wrong length for nickname including bad characters. This
1298 also applies to channel names. Affected file silcd/command.c.
1300 * Removed the lib/silcsilm/modules directory. Modules are now
1301 compiled into the lib/silcsim. Fixed the copying of the
1302 modules to follow symbolic links in Makefile.am.pre.
1304 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Fixed silc_string_regexify list creation. Fixes bugs with
1307 BAN and INVITE commands in server. The affected file is
1308 lib/silcutil/unix/silcunixutil.c.
1310 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Removed the command destructor entirely from the server's
1313 command and command reply routines. It is not needed, and
1314 its usage was buggy and caused crashes. Affected files are
1315 silcd/command[_reply].[ch].
1317 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Cancel protocol and NULL sock->protocol if timeout
1320 occurred during protocol. Affected file silcd/server.c.
1322 * Cancel protocol timeouts always before calling the final
1323 callback, to assure that after final callback is called
1324 no other state will be called for the protocol anymore.
1325 Affected file silcd/protocol.c.
1327 * Print error log if incoming connection configuration could
1328 not be found. Affected file silcd/server.c.
1330 * Fixed JOIN command to correctly save the founder mode
1331 to the client on normal SILC server, when the channel
1332 was created by the router. Affected file silcd/command.c.
1334 * Fixed LIST command (hopefully) to send correct reply
1335 packets. Affected file silcd/command.c.
1337 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * The silc_packet_receive_process now returns FALSE if the
1340 read data was invalid packet, and TRUE if it was ok.
1342 The server now checks that if unauthenticated connection
1343 sends data and its processing fails the server will close
1344 the connection since it could be a malicious flooder.
1346 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1348 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Make sure the warning about error opening a log file is
1351 printed only once and not everytime it fails (produces
1352 too much useless log). Affected file lib/silcutil/silclog.c.
1354 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1356 * Made the silc_server_daemonise() function more readable.
1357 Affected file silcd/server.c.
1359 * Pid file is now optional, the user may comment it out from
1360 the config file. Removed define SILC_SERVER_PID_FILE, we
1361 don't need a default any longer. Affected file
1362 configure.in.pre, lib/Makefile.am.pre.
1364 * Make some use of the pid file. The server now dies at startup
1365 if it detects a valid pid file on his path. The server would
1366 die anyway in this circumstance, because of the bind() failure.
1367 Affected file silcd/silcd.c.
1369 * No longer compiling lib/dotconf.
1371 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Fixed JOIN command parsing not to crash. Affected file
1374 lib/silcclient/command.c.
1376 * Fied the NICK_CHANGE notify to add the new client entry
1377 even it is resolved. This removes an <[unknown]> nick
1378 thingy bug in the client. Affected file is
1379 lib/silcclient/client_notify.c.
1381 * Do not try to allocate 0 bytes (efence does not like it)
1382 in lib/silccore/silccomand.c when encoding payload.
1384 * Do not take IRCNICK as nickname in Irssi SILC client since
1385 it is not possible to set nickname before hand connecting
1386 the server (TODO has an entry about adding auto-nicking
1389 * Changed the silc_server_command_pending to check whether
1390 there already exists an pending entry with the specified
1391 command, command identifier and pending callback. This is
1392 to fix IDENTIFY and WHOIS related crashes that may register
1393 multiple pending commands with same identifier. Affected
1394 file silcd/command.c.
1396 * Fixed the server to reconnect to the router even if it
1397 was already reconnecting and EOF was received. This to
1398 fix a possibility that the server wouldn't ever try to
1399 auto-reconnect to the router. Affected file silcd/server.c.
1401 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * Fixed the server's password authentication to use the
1404 length of the locally saved password, and not the one
1405 sent in the packet. Affected file silcd/protocol.c.
1407 * Fixed same password authentication problem in the
1408 Authentication Payload handling routines in
1409 lib/silccore/silcauth.c.
1411 * Yet another password authentication problem fixed with
1412 channel password handling in silcd/command.c.
1414 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * If first character of string in silc_parse_userfqdn is '@'
1417 then do not parse it. Affected file is
1418 lib/silcutil/silcutil.c.
1420 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1422 * Fixed minor bug in IDENTIFY command reply sending, which
1423 caused various weird problems during JOIN when it was
1424 resolving names for users. Affected file silcd/command.c.
1426 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Fixed the IDENTIFY command reply sending to chech better valid
1429 clients. It was possible to send incomplete list of replies.
1430 Affected file silcd/command.c.
1432 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Added silc_client_command[s]_[un]register functions now to
1435 dynamically register the commands in client library. Removed
1436 the static table of commands. This allows the client library
1437 to call commands without causing the application to know about
1438 what commands library has called.
1440 Removed the INFO command reply kludge to detect when the command
1441 was called by library. Now library use its own command reply
1442 function for INFO command.
1444 Added function silc_client_command_call to call a command.
1445 Application can use it to call command, not access the structure
1448 Now all commands that are sent by the client library (not
1449 explicitly sent by application) use own command reply functions.
1451 Affected files around lib/silcclient/ and in
1452 irssi/src/silc/core/.
1454 * Fixed the WHOIS command reply sending to chech better valid
1455 clients. It was possible to send incomplete list of replies.
1457 Fixed the WHOIS and IDENTIFY to send the request to router
1458 if normal server did not do it and did not find any results.
1460 Affected file silcd/command.c.
1462 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Moved the internal data from SilcClient context into its
1465 own file, not accesible to application. Affected files
1466 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1467 and other files in client library.
1469 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1471 * Added doc/examples installation target in Makefile.am.pre.
1474 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1477 commands the found client entry will be removed from the
1478 cache, after notifying application about the error. Affected
1479 file lib/silcclient/command_reply.c.
1481 * Changed the /MSG to check for exact nickname user gave, and
1482 not let `nick' match `nick@host' if it is only one found. Now,
1483 user must type the exact nickname (like nick@host2) even if
1484 there are no more than one same nicks found. This is to avoid
1485 a possibility of sending nickname to wrong nickname since
1486 `nick' could match `nick@host'. Affected file is
1487 irssi/src/core/silc-servers.c.
1489 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Do not print "you are now server operator" or similar when
1492 giving /away command. Affected files are
1493 irssi/src/silc/core/client_ops.c, silc-servers.h.
1495 * Made the silc_server_command_pending_error_check to send
1496 the same command reply payload it received back to the
1497 original sender of the command. This way all arguments
1498 that was received by the server will be received by the
1499 client too. Affected file silcd/command.c.
1501 * Added the silc_idcache_add to return the created cache entry
1502 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1504 * Add global clients to expire if they are not on any channel.
1505 This is because normal server will never know if they signoff
1506 if they are not on any channel. The cache expiry will take
1507 case of these entries. This is done by normal servers only.
1508 The affected files are silcd/command_reply.c,
1509 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1511 * If server receives invalid ID notification for WHOIS or
1512 IDENTIFY and the ID exists in the lists, it is removed.
1513 Affected file silcd/command_reply.c.
1515 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1516 in client then client entry that it matches is searched and
1517 the nickname is printed on the screen for user. Affected
1518 file irssi/src/silc/core/client_ops.c.
1520 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1522 * Use cache entry expire time in the LIST command reply to
1523 purge old entries from the cache after the LIST command
1524 reply has been received. This way we don't have non-existent
1525 entries in the cache for too long. Affected file is
1526 silcd/command_reply.c.
1528 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * If we are normal server, and we've not resolved client info
1531 in WHOIS or IDENTIFY from router, and it is global client,
1532 we'll check whether it is on some channel. If it is not
1533 then we cannot be sure about its validity and will resolve it
1534 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1535 file silcd/command.c.
1537 * Search channel by name (if possible) rather than by ID
1538 in IDENTIFY command's command reply. Affected file is
1539 silcd/command_reply.c.
1541 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1544 Updated specs and implemented it. Affected file silcd/command.c,
1545 silcd/packet_send.c and silcd/packet_receive.c.
1547 * Implemented the <founder auth> payload handling in the JOIN
1548 command. If provided all conditions for channel joining
1549 except requirement to provide correct passphrase can be
1550 overrided by the channel founder. Updated the protocol specs.
1551 Affected file silcd/command.c.
1553 Added support for founder auth in JOIN command in client
1554 library. Fixed the parsing of the JOIN command now to support
1555 all options as they should be. The affected file is
1556 lib/silcclient/command.c.
1558 * Optimized the WHOIS and IDENTIFY commands to send the request
1559 to router only if it includes nicknames or other names. If
1560 they include only IDs then check the local cache first before
1561 routing. Affected file is silcd/command.c.
1563 * Added channels topic announcements. Affected file is
1564 silcd/packet_receive.c and silcd/server.c.
1566 * Fixed the silc_server_send_notify_topic_set to really destine
1567 the packet to channel. Affected file silcd/packet_send.c.
1569 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1570 library. Affected file lib/silcclient/client_notify.c.
1572 * Added UMODE announcements. Affected file silcd/server.c.
1574 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * Memory leak fixes in:
1578 lib/silcutil/silcsockconn.c
1579 lib/silcske/silcske.c
1580 lib/silcske/groups.c
1582 lib/silccrypt/silcpkcs.c
1583 lib/silccore/silccommand.c
1584 lib/silccore/silcidcache.c
1589 * ROBOdoc documented the lib/silcske/groups.h file and a
1590 bit changed the interface for better.
1592 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1594 * Update the client entry context in the ID cache after
1595 nick change. Affected file lib/silcclient/command.c.
1596 Fixes the CUMODE command when regaining founder privileges,
1597 and a little WHOIS problem.
1599 * Fixed silc_net_gethostbyname to correctly call the
1600 inet_ntop. Affected file lib/silcutil/silcnet.c.
1602 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1604 * Added IPv6 support checking to the configure.in.pre, added
1605 also --enable-ipv6 option to override the check. Affected
1606 file configure.in.pre.
1608 * The silc_thread_create now calls the start function
1609 directly if threads support is not compiled in. Removes
1610 ugly #ifdef's from generic code. Affected files are
1611 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1613 * Added silc_net_gethostby[name/addr]_async to asynchronously
1614 resolve. Affected files are lib/silcutil/silcnet.[ch].

1625 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1626 routines. Added silc_net_is_ip[4/6]. Affected file is
1627 lib/silcutil/unix/silcunixnet.c. All routines that take
1628 address as argument now supports both IPv4 and IPv6 addresses.
1630 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1632 * Fixed LIST command reply sending in server. Affected file
1635 * Server now sends the kicker's client ID in the KICK notify
1636 to the kicked client. Affected file silcd/command.c.
1638 * The client library now parses the kickers client ID and
1639 UI displays it. Affected files lib/silcclient/client_notify.c
1640 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1642 * Made all payload parsing function prototypes consistent.
1643 They all take now const unsigned char * and uint32 pair as
1644 the payload data instead of SilcBuffer. Changes all around
1645 the source tree. Other unsigned char* -> const unsigned char*
1646 changes around the tree as well.
1648 * Optimized SFTP client and server packet sending not to
1649 allocate new buffer for each packet but to recycle the
1650 first allocated buffer. Affected files are
1651 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1653 * Optimized the SFTP client to use SilcList instead of
1654 SilcDList for requests, because it is faster. Affected file
1655 is lib/silcsftp/sftp_client.c.
1657 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1658 into lib/silccore/silcid.[ch].
1660 Renamed silcpayload.[ch] into silcargument.[ch].
1662 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * If client entry is deleted with active key agreement
1665 session, abort the session.
1667 The silc_client_abort_key_agreement now calls the completion
1668 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1670 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1673 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Don't use __restrict in older GCC's. Affected file is
1676 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1678 * silc_net_localhost now attempts to reverse lookup the
1679 IP/hostname. Affected file lib/silcutil/silcnet.c.
1681 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1682 command. It can be used to gain founder privileges at
1683 the same time when joining the channel.
1685 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1686 kicker's client ID as well. Updated protocol specs.
1688 Defined that the server must send SILC_COMMAND_IDENTIFY
1689 command reply with error status to client who sent
1690 private message with invalid client ID.
1692 Updated the protocol specification.
1694 * Added silc_server_send_command_reply to send any
1695 command reply. Affected file silcd/packet_send.[ch].
1697 * Added silc_id_payload_encode_data to encode ID payload
1698 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1700 * The server now send IDENTIFY command reply with error
1701 status if client ID in private message is invalid. Affected
1702 file silcd/packet_receive.c.
1704 * Save the server key file with server's IP address in
1705 the filename instead of hostname. The affected file is
1706 irssi/src/silc/core/client_ops.c.
1708 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1713 * Added libtool support for compiling shared objects in
1714 lib/silcsim. Affected file configure.in.pre and
1715 lib/silcsim/Makefile.am. Original patch by cras.
1717 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Pid file configuration, and server's config file fixes
1720 patch by toma. Updated CREDITS file.
1722 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Fixed silc_client_channel_message to not try to decrypt
1725 the message twice if it resolved the destination client
1726 information. This could cause of dropping one channel
1727 message. Affected file lib/silcclient/client_channel.c.
1729 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1732 lib/silcclient/client.c. This function is used when the SILC
1733 Client is run under some other scheduler, or event loop or
1734 main loop. On GUI applications, for example this may be
1735 desired to used to run the client under the GUI application's
1736 main loop. Typically the GUI application would register an
1737 idle task that calls this function multiple times in a second
1738 to quickly process the SILC specific data.
1740 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1742 * Fixed silc_server_drop() for dropping the supplementary
1743 groups as well, this could cause a security hole on some
1746 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1751 * Write PID file after dropping privileges. Added -F option
1752 to run server on foreground. A patch by debolaz.
1753 Affected files silcd/server.c, silcd/silcd.c.
1755 * Fixed MOTD to return the MOTD file server name. Affected
1756 file silcd/command.c.
1758 * Added INFO command reply handling to the Irssi SILC Client.
1759 Affected file irssi/src/silc/core/client_ops.c.
1761 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Fixed the silc_idcache_list_* routines to really support
1764 the dynamic list. Fixes a crash. Affected file is
1765 lib/silccore/silcidcache.c.
1767 * Fixed the LIST command reply to really call LIST command's
1768 pending callbacks. Affected file silcd/command_reply.c.
1770 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1772 * Update conn->local_entry->nickname after giving NICK
1773 command. Affected file lib/silcclient/command.c.
1775 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1777 * Added the [pid] option to the silcd configuration file
1779 Affected files: serverconfig.[ch] and silcd.c
1781 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Save fingerprint in WHOIS command reply in server.
1784 Affected file silcd/command_reply.c.
1786 * Fixed NICK commands pending callback registration.
1787 Affected file lib/silcclient/command.c.
1789 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1791 * Use ++server->cmd_ident when sending commands in server,
1792 instead of random number. Affected file silcd/command.c.
1794 * Fixed GETKEY command reply to call actually GETKEY pending
1795 command callbacks. Affected file silcd/command_reply.c.
1797 * A bit stricter check for nicknames. Check for same nickname
1798 in NICK command also. Affected file silcd/command.c.
1800 * Do not call INFO command everytime client ID changes, only
1801 during first connecting. Affected file lib/silcclient/client.c.
1803 * Set the new nickname only after successful command reply for
1804 NICK command is returned by server. Affected file
1805 lib/silcclient/command.c.
1807 * Remove nicknames from nicklist during server_signoff notify.
1808 Should fix /NAMES bit more. The affected file is
1809 irssi/src/silc/core/silc-channels.c.
1811 * Added `fingerprint' field to the SilcIDListData in the
1812 silcd/idlist.h to hold the fingerprint of the client's
1815 Send the fingerprint of the client's public key in WHOIS
1818 Affected files silcd/command.c, and silcd/idlist.[ch].
1820 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1821 create fingerprint from given data.
1823 * Show the fingerprint of the client's public key in WHOIS.
1824 Affected files irssi/src/module-formats.[ch] and
1825 irssi/src/silc/core/client_ops.c.
1827 * Format the multiple same nicknames also during JOIN and
1828 NICK_CHANGE notifys. Affected file is
1829 lib/silcclient/client_notify.c.
1831 * Do not print error on screen for invalid private message
1832 payload since it can come if someone is sending private
1833 messages with wrong key. Affected file
1834 lib/silccore/silcprivate.c.
1836 * Fixed multiple concurrent /PING crash. Affected file
1837 lib/silcclient/command.c.
1839 * Changed the wrong ID encoding. All IP addresses must be
1840 in MSB first order in encoded format. They were encoded
1841 wrong and was in LSB format. Affected files are
1842 silcd/serverid.c, lib/silcutil/silcutil.c.
1844 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1846 * Call the `connect' client operation through the scheduler
1847 in case of error. Affected file lib/silcclient/client.c.
1849 * Call the `failure' client operation even if the error
1850 occurred locally during a protocol. Affected file is
1851 lib/silcclient/protocol.c.
1853 * Added support of sending LIST command to router from normal
1854 server. This way normal server can get list of all channels
1855 in the network too. Fixed the channel list sending in the
1856 server too. Affected files are silcd/command.c, and
1857 silcd/command_reply.[ch].
1859 * Added silc_server_update_channels_by_server and
1860 silc_server_remove_channels_by_server. They are used during
1861 disconnection of primary router and in backup router protocol.
1862 Affected file silcd/server_util.[ch], silcd/server.c and
1863 silcd/server_backup.c.
1865 * Fixed channel adding to global list in IDENTIFY command
1866 reply in server. Affected file silcd/command_reply.c.
1868 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * If the incoming packet type is REKEY or REKEY_DONE process
1871 that packet always synchronously. Fixes yet another MAC
1872 failed error on slow (dialup) connections. Affected file
1873 lib/silcclient/client.c and silcd/server.c.
1875 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1877 * Call check_version SKE callback for initiator too. Affected
1878 file lib/silcske/silcske.c.
1880 * Implemented fix for security hole found in the SKE that was
1881 fixed in the specification few days back; the initiator's
1882 public key is now added to the HASH value computation.
1883 Added backwards support for the old way of doing it too, for
1884 old clients and old servers. Affected file is
1885 lib/silcske/silcske.c.
1887 * Enabled mutual authentication by default in SKE. If initiator
1888 is not providing mutual authentication the responder will
1889 force it. This will provide the proof of posession of the
1890 private key for responder. The affected files are
1891 lib/silcclient/protocol.c and silcd/protocol.c.
1893 * Do not cache anymore the server's public key during SKE.
1894 We do mutual authentication so the proof of posession of
1895 private key is done, and if the server is authenticated in
1896 conn auth protocol with public key we must have the public
1897 key already. Affected file silcd/protocol.c.
1899 * Added new global debug variable: silc_debug_hexdump. If
1900 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1901 file lib/silcutil/silclog.[ch].
1903 * Fixed compilation warning due to char * -> const char *.
1904 Affected files lib/silcutil/silcnet.h, and
1905 lib/silccore/silcauth.[ch].
1907 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Fixed CMODE command when new channel key was created. If
1910 the creation failed the old key was removed. Next time giving
1911 same command would crash the server since the old key was
1912 freed already. Affected file silcd/command.c.
1914 * Fixed the silc_server_announce_get_channels to not crash
1915 on reconnect. Affected file silcd/server.c.
1917 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Added silc_log_set_debug_string function to set a regex
1920 string to match for debug output. Only the function names,
1921 or filenames matching the given debug string is actually
1922 printed. This way it is possible to filter out those debug
1923 strings that user is not interested in.
1925 Fixed a bug in silc_string_regexify.
1927 Affected files lib/silcutil/silclog.[ch], and
1928 lib/silcutil/unix/silcunixutil.c.
1930 * Changed the -d options in both server and Irssi SILC client
1931 to take the debug string as argument. Affected files
1932 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1934 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Added silc_hash_babbleprint to create a Bubble Babble
1937 Encoded fingerprint. The encoding is developed by Antti
1938 Huima (draft-huima-babble-01.txt), and it creates human
1939 readable strings out of binary data. Affected file
1940 lib/silccrypt/silchash.[ch].
1942 * Print the babble print now in addition of fingerprint as well
1943 in Irssi SILC client. Affected files are
1944 irssi/src/fe-common/silc/module-formats.[ch],
1945 irssi/src/fe-common/silc/core/client_ops.c.
1947 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Fixed a security problem found in SKE. The initiator's
1950 public key too is now added to the HASH hash value creation
1951 which is signed by the responder to create the SIGN value.
1952 This will prevent anyone in the middle to lie to the responder
1953 about the initiator's public key. If this is done now, the
1954 man in the middle will get caught. Updated the protocol
1957 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Better installation directory handling. Configure module
1960 paths and other paths automatically to example_silc* files
1961 in doc/. A patch by toma.
1963 * Fixed compiler warning from MPI library, and from SILC RNG.
1966 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1967 It can be configured with ./configure. A patch by toma.
1969 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Find correct make to use in prepare-clean. A patch by
1972 toma. Affected file prepare-clean.
1974 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1976 * Added irssi variables use_auto_addr, auto_bind_ip,
1977 auto_bind_port and auto_public_ip.
1979 * Changed the interface for silc_client_send_key_agreement
1980 in lib/silcclient/silcapi.h
1984 irssi/src/silc/core/silc-core.c
1986 lib/silcclient/silcapi.h
1987 irssi/src/silc/core/silc-channels.c
1988 lib/silcclient/client_keyagr.c
1991 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Added silc_pkcs_public_key_compare to compare two
1994 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1996 * Check that the client who set the founder mode on the
1997 channel is the same client that is giving the founder
1998 mode to itself. It is done by comparing the saved public
1999 key (it is saved even in the authentication is passphrase).
2000 Affected file silcd/command.c.
2002 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Do not process packet for disconnected socket connection.
2005 Affected file lib/silccore/silcpacket.c.
2007 * Process the DISCONNECT packet through scheduler in the
2008 client library. Affected file lib/silcclient/client.c.
2010 * Fixed the silc_client_packet_parse to not to increase
2011 the packet sequence number if the conn->sock and the
2012 current socket connection is not same. This can happen
2013 for example during key agreement when the conn includes
2014 multiple socket connections (listeners). Affected file
2015 lib/silcclient/client.c.
2017 * The sender of the file transfer request now provides also
2018 the pointer (listener) for the key exchange protocol. If
2019 the listener cannot be created then it sends empty key
2020 agreement and lets the receiver provide the listener.
2022 Added `local_ip' and `local_port' arguments to the
2023 silc_client_file_send. If they are provided they are used,
2024 if not then it will attempt to find local IP address, if
2025 not found or bind fails then the remote client will provide
2028 Affected files are lib/silcclient/client_ftp.c and
2029 lib/silcclient/silcapi.h.
2031 * Extended the FILE SEND command to support defining the
2032 local IP and port for key exchange listener. They are
2033 optional. Affected file irssi/src/silc/core/silc-servers.c.
2035 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Defined to WHOIS command reply the sending of fingerprint
2038 of the client's public key (if the proof of posession of the
2039 corresponding private key is verified by the server).
2040 Updated to the protocol specification.
2042 * Added support of receiving the client's public key's
2043 fingerprint in command reply in client library. Affected
2044 file is lib/silcclient/command_reply.c, and
2045 lib/silcclient/idlist.[ch].
2047 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Do not send over 128 chars long nickname to the server
2050 in NICK command. Affected file lib/silcclient/command.c.
2052 * Do not send over 256 chars long channel names to the server
2053 in JOIN command. Affected file lib/silcclient/command.c.
2055 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Assure that silc_server_close_connection cannot be called
2058 twice for same socket context. Affected file is
2061 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2063 * Send error message to application if opening file for
2064 writing during file transfer fails. Affected file is
2065 lib/silcclient/client_ftp.c.
2067 Remove all file transfer sessions for a client that we're
2068 removing from ID cache.
2070 Affected file is lib/silcclient/client_ftp.c.
2072 * Fixed silc_net_addr2bin to return correct address. Affected
2073 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2075 * Fixed file transfer session removing on signoff notify.
2076 Affected file irssi/src/silc/core/silc-servers.c.
2078 * Added the SilcClientFileError to be returned in the monitor
2079 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2080 Affected file lib/silcclient/silcapi.h.
2082 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Fixed a crash in silc_client_ftp_free_sessions and
2085 silc_client_ftp_session_free_client. Affected file
2086 lib/silcclient/client_ftp.c.
2088 * Added `disabled' field in the SilcChannelEntry in the server
2089 to indicate if the server entry is disabled. Affected file
2090 silcd/idlist.h, silcd/command[_reply].c.
2092 * SILC server adds now /var/run/silcd.pid everytime it is
2093 started. Affected file silcd/silcd.c.
2095 * Added silc_server_packet_send_clients to send a packet to
2096 the provided table of client entries. Affected file
2097 silcd/packet_send.[ch].
2099 * Fixed a crash in client resolving in client_prvmsg.c in
2100 client library. Affected file lib/silcclient/client_prvmsg.c.
2102 * Do not actually remove the client directly from ID cache
2103 during SERVER_SIGNOFF, but invalidate it. This way we
2104 preserve the WHOWAS info for the client. Affected file
2105 silcd/server_util.c.
2107 * Fixed SERVER_SIGNOFF notify handling in the server. The
2108 server is now able to process incoming SERVER_SIGNOFF notify
2109 for a server that it doesn't even know about. It will remove
2110 the clients provided in the notify. Affected file
2111 silcd/packet_receive.c.
2113 * Check for partial packet in data queue after every packet that
2114 was found from the queue. Return and wait for more data if
2115 there is partial data in queue. Affected file is
2116 lib/silccore/silcpacket.c.
2118 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Added SilcClietFileError enum to indicate error in
2121 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2122 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2123 Affected files lib/silcclient/silcapi.h and
2124 lib/silcclient/client_ftp.c.
2126 * Check that newsize in silc_buffer_realloc is larger than
2127 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2129 * Added better monitor of file transfers. It now monitors
2130 key agreement protocol during the file transfer too. Added
2131 error reporting too. Affected files
2132 irssi/src/silc/core/silc-servers.c,
2133 irssi/src/fe-common/silc/module-formats.[ch].
2135 * Wrote a help file for FILE command.
2137 * Added silc_rng_global_get_byte_fast to get not-so-secure
2138 random data as fast as possible. Random data is read from
2139 /dev/urandom if available and from the SILC RNG if not
2140 available. It is used in padding generation. Affected file
2141 lib/silccrypt/silcrng.[ch].
2143 * All packets in client library are now processed synchronously.
2144 Optimized packet processing a lot. Affected file
2145 lib/silcclient/client.c.

2148 now in server, to optimize packet processing. Affected file
2151 * Include files are installed now only in Toolkit distribution
2152 if make install is given. Affected files: all Makefile.am's.
2154 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Assure that silc_client_notify_by_server_resolve does not
2157 resolve the client information multiple times. If it cannot
2158 be found by the first it cannot be found at all. Affected
2159 file lib/silcclient/client_notify.c.
2161 * Fixed WHOWAS command reply calling. Affected file
2162 lib/silcclient/command_reply.c.
2164 * Removed all references to silc_idlist_get_client from the
2165 Irssi SILC client since that call is internal call used by
2166 the library. The Irssi SILC client will use now client
2167 retrieval functions found in silcapi.h.
2169 * Fixed a bug in resolving nickname info before sending
2170 private message. It used freed memory. Affected file
2171 irssi/src/silc/core/silc-servers.c.
2173 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Assure my_channels statistics cannot go negative in server.
2176 Affected files silcd/server.c, silcd/server_util.c.

2192 * Added silc_net_localip to return local host's IP address.
2193 Affected file lib/silcutil/silcnet.[ch].
2195 * If key exchange or rekey protocol is active for a connection
2196 parse all packets syncronously since there might be packets
2197 in packet queue that we are not able to process without first
2198 processing packets before them. Affected file silcd/server,
2199 lib/silcclient/client.c.
2201 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2202 whether library should continue processing the packet.
2203 Affected file lib/silccore/silcpacket.h.

2234 lib/silcutil/silcutil.[ch].
2236 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Resolve the client info when received private message or
2239 channel message for a client which nickname we don't know.
2240 Affected files lib/silcclient/client_prvmsg.c and
2241 lib/silcclient/client_channel.c.
2243 * Do not crash in /KEY if client is not connected. Affected
2244 file irssi/src/silc/core/silc-channels.c.
2246 * Added SilcClientStatus field to the SilcClientEntry in the

2249 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2250 is incomplete and is being resolved, it won't be resolved
2253 Make sure also that USERS command reply does not resolve
2254 twice information. Affected file is
2255 lib/silcclient/command_reply.c.
2257 Make sure that silc_client_get_clients_by_list does not
2258 resolve twice same information.
2260 * Check for valid client->id in the silc_server_free_client_data.
2261 Affected file silcd/server.c.
2263 * Fixed /GETKEY nick@server not to crash if the server entry
2264 is not found. Affected file lib/silcclient/command.c.
2266 * Fixed the silc_server_check_cmode_rights to check the
2267 requested modes correctly. Affected file silcd/command.c.

2271 * Better checks for non-printable chars in nick added.
2272 Affected file silcd/command.c.
2274 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Call the silc_server_udpate_servers_by_server in the
2277 primary router that comes back online in the backup resuming
2278 protocol. Otherwise it routes packets wrong. Affected file
2279 silcd/server_util.[ch], silcd/server_backup.c.
2281 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2284 lib/silcutil/silcbuffmt.[ch].
2286 * Redefined the SILC packet header to include the padding
2287 length. Affected file lib/silccore/silcpacket.[ch].
2289 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2290 length for maximum padding up to 128 bytes). Affected
2291 file lib/silccore/silcpacket.h.
2293 * Removed all backwards support for old 0.5.x MAC thingies.
2294 The SILC packet header change makes it impossible to be
2295 backwards compatible.
2297 * Send the ENDING packet with timeout in the backup resuming
2298 protocol. This is to assure that all routers has connected
2299 to the primary router. Affected file silcd/server_backup.c.
2301 * Changed the RNG to take the first IV from random data. It
2302 used to take it from zero actually. Changed the RNG also
2303 to use /dev/urandom during session. /dev/random is used
2304 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2306 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Changed the SILC packet header to have the first two bytes
2309 (the packet length) encrypted. Affected files aroung the
2310 code tree, lib/silccore/silcpacket.[ch]. Removed the
2311 SilcPacketCheckDecrypt callback. It is not needed anymore
2312 since the silc_packet_receive_process will determine now
2313 whether the packet is normal or special.
2315 * Implemented the unidirectional MAC keys. Affected files
2316 lib/silcske/silcske.c, silcd/protocol.c and
2317 lib/silcclient/protocol.c.
2319 * Implemented the packet sequence number to the MAC computation.
2320 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2321 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2322 lib/silcclient/protocol.c.
2324 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Allow backup router to announce servers. All servers
2327 announced by backup router are added to the global list
2328 automatically. Update hte server's socket to our primary
2329 router also when backup router announces a server.
2330 Affected file silcd/packet_receive.c.
2332 * Do not update the client->router in the function
2333 silc_server_udpate_clients_by_server if the client is on
2334 global list. We might fail to find any specific server
2335 for locally connected clients and local cell clients. They
2336 should still use the `from' and not `to' as client->router.
2337 This fixes backup router resuming protocol. Affected file
2338 silcd/server_util.c.
2340 * Decrease channel statistics count only if the channel
2341 deletion worked. Affected files are silcd/server.c and
2342 silcd/server_util.c.
2344 * Added silc_server_update_servers_by_server to update origin
2345 of all server entries. Used during backup router protocol.
2346 Affected files silcd/server_util.[ch], silcd/server.c. and
2347 silcd/backup_router.c.
2349 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2350 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2351 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2352 lib/silccrypt/silchmac.c.
2354 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Assure that router cannot reroute the same channel message
2357 to the sender. Affected file silcd/packet_receive.c.
2359 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * Made better checks that the channel message is not sent
2362 to the router it came from. Affected file is
2363 silcd/packet_send.c. Fixed memory leak too.
2365 * Announce informations for incoming router connection, but
2366 only after checking if it is replaced by backup router.
2367 Affected file silcd/packet_receive.c.
2369 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Fixed the backup resuming protocol to work in multiple
2372 router environment. Affected file silcd/server_backup.c.
2374 * Route packet only to one router in the function
2375 silc_server_packet_send_to_channel. Affected file is
2376 silcd/packet_send.c.
2378 * Fixed silc_server_send_notify_dest to set the broadcast
2379 flag. Fixed the silc_server_send_notify_topic to actually
2380 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2381 Affected file silcd/packet_send.c.
2383 * Changed the SFTP Filesystem interface. Changed the
2384 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2385 the filesystem operation function. The SilcSFTPFilesystem
2386 is now a context that is allocated by all filesystem allocation
2387 functions and it already includes the operations structure
2388 and filesystem specific context. It is given as argument
2389 now to the silc_sftp_server_start. This made the interface
2390 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2391 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2393 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * Changed the backup router adding and getting interfaces
2396 in the server. The router that will be replaced by the
2397 specified backup router is now sent as argument. Affected
2398 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2401 * Added silc_net_addr2bin_ne to return the binary form of
2402 the IP address in network byte order. Affected files
2403 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2405 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Check for existing server ID in silc_server_new_server
2408 and in silc_server_connect_to_router_final and remove the
2409 old entry if it exists. Affected file silcd/packet_receive.c,
2412 * Send the channel message always to only one router, either
2413 in upstream or downstream. Affected file is
2414 silcd/packet_send.c.
2416 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Wrote the definition of the backup resuming protocol to the
2419 protocol specification.
2421 * Removed one redundant channel key generation from normal
2422 server during joining procedure. Removed one redundant
2423 channel key sending from server to router during joining
2424 procedure. Affected file silcd/command.c.
2426 * Made minor bugfixes to the backup router resuming protocol.
2427 Affected file silcd/server_backup.c, server.c.

2432 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2435 * Implemented the backup resuming protocol that is used to
2436 resume the primary router position in the cell after the
2437 primary router comes back online. Affected files
2438 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2439 and silcd/server_util.[ch].
2441 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Sleep two (2) seconds after sending QUIT command to server.
2444 Affected file lib/silcclient/command.c.
2446 * Assure that if outgoing data buffer is pending do not force
2447 send any data. Affected file silcd/packet_send.c.
2449 * Assure that if outgoing data buffer is pending do not force
2450 send any data. Affected file lib/silcclient/client.c.
2452 * Implemented the backup router support when the primary router
2453 goes down. The servers and routers can now use the backup
2454 router as new primary router without loosing connectivity.
2456 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2459 in the server to indicate disabled entry. All data read
2460 from the connection will be ignored and no data is sent
2461 for entry that is disabled. Affected files are
2462 silcd/idlist.h, silcd/server.c.
2464 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Created SFTP client and server test programs in the
2467 lib/silcsftp/tests directory.
2469 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Implemented memory filesystem (virtual filesystem) for
2472 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2475 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Implemented the SFTP (SSH File Transfer Protocol) to the
2478 lib/silcsftp. It includes SFTP client and SFTP server
2481 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Moved lib/silccore/silcprotocol.[ch] to the
2484 lib/silcutil library.
2486 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2487 take variable argument list pointer as argument. Affected
2488 file lib/silcutil/silcbuffmt.[ch].
2490 * Added silc_buffer_set function that is used to set data
2491 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2492 Affected file lib/silcutil/silcbuffer.h.
2494 * Changed various routines in the core library to use the new
2495 silc_buffer_set instead of allocating new buffer only for
2498 * Added 64-bit value formatting and unformatting support to the
2499 silc_buffer_[un]format routines. Affected file is
2500 lib/silcutil/silcbuffmt.[ch].
2502 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2503 to includes/bitmove.h.
2505 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2507 * Fixed channel user mode saving in client library. Affected
2508 file lib/silcclient/command[_reply].c.
2510 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2512 * Defined the file transfer to the SILC Protocol. Added
2513 new packet type SILC_PACKET_FTP and defined File Transfer
2514 Payload. The mandatory file transfer protocol is SFTP
2515 (SSH File Transfer Protocol). Affected file in addition
2516 of the internet draft is lib/silccore/silcpacket.h.
2518 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2519 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2520 is used as part of backup router protocol when the primary
2521 router of the cell is back online and wishes to resume
2522 the position as primary router.
2524 * Redefined the MAC generation keys in the protocol. The
2525 same key is not used anymore in both direction. Both
2526 direction will now use different keys for sending and
2527 receiving. This fixes a potential security flaw. This
2528 change causes incompatibilities in the protocol.
2530 * Redefined also the MAC computation from the packet.
2531 An packet sequence number is now added to the MAC
2532 computation. This prevents possible replay attacks against
2533 the protocol. This change too causes incompatibilities
2536 Added `sequence' field to the SilcPacketContext to hold
2537 the current sequence number for the packet.
2539 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Added `created' field to the SilcIDListData in the file
2542 silcd/idlist.h to indicate the time when the entry was
2545 * Added `created' field to the SilcChannelEntry too. Affected
2546 file silcd/idlist.h.
2548 * Added `creation_time' aguments to all the announcement functions
2549 in the server. If it is provided then only the entries that
2550 was created after the provided time frame are actually
2551 announced. Affected file silcd/server.[ch].
2553 * The protocol says that the Channel ID's IP address must be
2554 based on the router's IP address. Added check for this in
2555 the silc_server_new_channel when processing incoming New Channel
2556 Payload. Affected file silcd/packet_receive.c.
2558 * Print out the correct version with --version in SILC client.
2559 Affected file irssi/src/silc/core/silc-core.c.
2561 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Fixed WHOWAS command to check for completnes of the client
2564 entry always, not just when the command is coming from client.
2565 Affected file silcd/command.c.
2567 * Added new function silc_server_packet_queue_purge to purge the
2568 outgoing data queue to the network. After the function returns
2569 it is guaranteed that the outgoing packet queue is empty.
2570 Affected file silcd/packet_send.[ch].
2572 * Purge the outgoing packet queue in the rekey protocol's final
2573 callback to assure that all rekey packets go to the network
2574 before quitting the protocol. Affected file silcd/server.c.
2576 * Added silc_client_packet_queue_parse as similar function as
2577 in server to the client library. The affected file is
2578 lib/silcclient/client.c.
2580 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Splitted silcd/server.c and created silcd/server_util.[ch]
2583 for utility functions.
2585 * Added new socket flag SILC_SF_DISABLED to indicate that the
2586 connection is open but nothing can be sent to or received from
2587 the connection. Affected file lib/silcutil/silsockconn.[ch].
2588 The checking for disabled socket is checked in the low level
2589 silc_socket_write and silc_socket_read functions.
2591 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Allow only nicknames and channel names that fits into the
2594 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2596 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * When processing JOIN command reply in server check that if
2599 the channel exists in our global list we'll move it the local
2600 list. Affected file silcd/command_reply.c.
2602 * Fixed the check whether client is joined on the channel already
2603 in JOIN command. Affected file lib/silcclient/command.c.
2605 * Fixed the JOIN command reply to check whether the channel
2606 already exists. Affected file lib/silcclient/command_reply.c.
2608 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Added silc_ske_status_string to map the SKE error numbers
2611 to readable strings. The affected files are
2612 lib/silcske/silcske[_status].[ch].
2614 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Do not show the private channels on the WHOIS channel list
2617 as it is not allowed by the protocol. The affected file is
2620 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Assure that the packet length digged from the actual packet
2623 is something sensible in the silc_packet_decrypt_rest_special
2624 in lib/silccrypt/silcpacket.c.
2626 * Free and NULL the allocated pointer in silc_hmac_alloc if
2627 the HMAC allocation fails. The affected file is
2628 lib/silccrypt/silchmac.c.
2630 * Print the selected security properties to the log files in
2631 the server. Affected file silcd/protocol.c.
2633 * Add SKE's reference counter even if calling the completion
2634 callback manually. Otherwise it goes negative, although it
2635 does not cause any problems. The affected file is
2636 lib/silcske/silcske.c.
2638 * Remove the client entry with short timeout after giving the
2639 KILL command. Affected file lib/silcclient/command.c.
2641 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2642 case all found clients are already disconnected (WHOWAS would
2643 found them) in the server. Affected file silcd/command.c.
2645 * Update the last_receive (time of last data received) to be
2646 updated only when received private or channel message so that
2647 the idle time showed in WHOIS makes more sense.
2649 * Added boolean field `valid' in to the SilcClientEntry in the
2650 client library to indicate whether the entry is valid or not.
2651 This fixes the nickname change bug on channel when changing
2652 the nickname to be same than the old (like nick to Nick) the
2653 nickname formatter doesn't set the new nick anymore to Nick@host.
2654 Affected file lib/silcclient/idlist.[ch].
2656 * Now actually fixed the nickname changing on disconnection.
2657 Added new function silc_change_nick to the Irssi SILC Client.
2658 Affected file irssi/src/silc/core/client_ops.c,
2659 irssi/src/silc/core/silc-nicklist.[ch].
2661 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Check that the public key exists in the GETKEY command before
2664 trying to encode it. Affected file silcd/command.c.
2666 * Print some notifications on received public keys with GETKEY
2667 command in the Irssi SILC Client. Affected files are
2668 irssi/src/fe-common/silc/module-formats.[ch],
2669 irssi/src/silc/core/client_ops.c.
2671 * Use IDENTIFY command to resolve the server information in the
2672 GETKEY command instead of INFO command. Affected file
2673 lib/silcclient/command.c.
2675 * All command reply functions in the client library now calls
2676 the pending command reply callbacks even if an error has
2677 occurred. The server has done this a long time and now it was
2678 time to move the client library to this as well. Now all
2679 errors can be delivered back to the pending command reply
2680 callbacks if necessary. Affected files are
2681 lib/silcclient/command[_reply].[ch].
2683 * Change the nickname on disconnection back to the username
2684 because in reconnect the server will enforce it to it anyway.
2685 Affected file irssi/src/silc/core/silc-servers.c.
2687 * Fixed a config file parsing bug in the Irssi SILC client.
2688 Affected file irssi/src/silc/core/clientconfig.c.
2690 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * When printing the channel mode on JOIN, verify that the
2693 channel key and channel's HMAC are valid. Affected file
2694 irssi/src/silc/core/client_ops.c.
2696 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2698 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2699 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2700 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2702 * Removed channel key rekey task deleting from the function
2703 silc_server_save_channel_key. Affected file silcd/server.c.
2704 Added explicit timeout task context instead that is used to
2705 delete the task if we are registering a new task before the
2706 new task has elapsed.
2708 * When channel key rekey occurs the client library now saves
2709 the old channel key for a short period of time (10 seconds) and
2710 is able to use it in case some is still sending channel
2711 messages encrypted with the old key after the rekey. Affected
2712 file lib/silcclient/[idlist.h|client_channel.c].
2714 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Added check to the silc_server_new_id_real to not accept
2717 new ID if it is the sender's own ID. Affected file is
2718 silcd/packet_receive.c.
2720 * Assure that we do not announce ourself or the one we've
2721 sending our announcements when we're router and are announcing
2722 servers to our primary router. Affected file silcd/server.c.
2724 * Fixed silc_server_command_identify_check_client to assemble
2725 correct WHOIS packet. It send corrupted WHOIS packet and
2726 caused problem with router to router connections. Affected
2727 file silcd/command.c.
2729 Fixed also silc_server_command_whois_check the same way
2730 as for the IDENTIFY command.
2732 * Added new SilcIDListStatus to the server in the SilcIDListData
2733 structure. The status now includes the current status of
2734 the entry (like registered, resolved etc.). Affected file
2735 silcd/idlist.[ch]. Defined a bunch of different status types
2736 as well. This replaced the old boolean registered field as well.
2738 Added resolve_cmd_ident field to the SilcClientEntry structure
2739 too so that if the entry is for example being resolved so
2740 another command may attach to the same pending command reply
2741 without requiring to resolve the same entry again. This concept
2742 should optimize the WHOIS and the IDENTIFY resolving under
2743 heavy load by taking away unnecessary resolving for entries
2744 that are being resolved already.
2746 Added support for adding multiple pending commands for one
2747 command idenfier. Affected file silcd/command[_reply].[ch].
2749 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2750 before deleting the data. Otherwise the hash table will have
2751 freed data in comparison functions. Affected file is
2752 silcd/command_reply.c.
2754 * Fixed silc_idlist_replace_client_id to add the new entry to
2755 the cache with NULL nickname. Otherwise there will be invalid
2756 memory as the nickname after the nickname is freed. Affected
2757 file silcd/packet_receive.c.
2759 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2760 saved into wrong slots because the previous number of entries
2761 was not taken into account. Affected file silcd/idlist.c.
2762 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2764 * If we are router and we receive JOIN notify to a channel that
2765 does not have any users then notified client is marked as the
2766 channel founder, as it is it. The affected file is
2767 silcd/packet_receive.c
2769 * Added to the extended hash table API's table_del_*ext functions
2770 the destructor as argument too, so that the caller can decide
2771 which destructor to use or whether to use destructor at all.
2772 Affected file lib/silcutil/silchashtable.[ch].
2774 * Fixed ID Cache purging. It actually deleted the entries from
2775 the hash table after the data was freed. The hash table ended
2776 up comparing freed memory. The affected file is
2777 lib/silccore/silcidcache.c.
2779 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Fixed Irssi SILC client's KILL command's HELP syntax.
2783 * The USERS command now resolves the detailed user information
2784 if the userinfo field is missing. Affected file is
2785 lib/silcclient/command_reply.c.
2787 * Do not print error in silc_file_read if the read file does
2788 not exist. Just silently return NULL. Affected file is
2789 lib/silcutil/silcutil.c.
2791 * Fixed the silc_log_output to not wine about NULL filename
2792 and to not create some bogus " " filename. Affected file is
2793 lib/silcutil/silclog.c.
2795 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Fixed various printing bugs on the user interface in the
2798 Irssi SILC Client. Minor changes that were forgotten from
2801 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Fixed the configure.in.pre and the compilation and distribution
2804 environment to support the new autoconf 2.52. That version is
2805 now required to compile the CVS trunk.
2807 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2810 to generally parse user@fqdn format strings. Affected file
2811 lib/silcutil/silcutil.c.
2813 * Added nickname_format and nickname_force_format fields to the
2814 SilcClientParams structure. The first one defines the format
2815 for the nicknames that the library will enforce if the receives
2816 multiple same nicknames. The second one is boolean value and
2817 can be used to force the library to always enforce the format
2818 to the nicknames regardles whether there are multiple nicknames
2819 or not. This configurable formatting was employed to flexibly
2820 support accessing multiple nicknames from the user interface.
2821 The userinterface can now set the nicknames to what ever format
2822 they prefer. Affected file lib/silcclient/silcapi.h.
2824 Added function silc_client_nickname_format to the file
2825 lib/silcclient/idlist.c. It performs the nickname formatting.
2827 Added new field `hostname´ to the SilcClientEntry context.
2828 It holds the hostname of the client. Affected file is
2829 lib/silcclient/idlist.h.
2831 * Irssi SILC Client sets the nicknames in nick@hostn format.
2832 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2833 irssi/src/silc/core/silc-core.c.
2835 The WHOIS printing now also shows both the real nickname and
2836 the formatted nickname so that user knows how to access the
2837 user if there are multiple same nicknames cached. Affected
2838 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2839 printing formatting too to take the hostname now as a separate
2840 argument. The Affected file is
2841 irssi/src/fe-common/silc/modules-formats.[ch].
2843 * Changed the silc_client_get_clients_local to accept the formatted
2844 nickname as argument. It accepts the real nickname too but the
2845 formatted nickname can be used to find the true entry from
2846 multiple entries. Affected file lib/silcclient/silcapi.h and
2847 lib/silcclient/idlist.c.
2849 * Added nickname_format_parse field to the SilcClientParams.
2850 It is a callback function provided by the application to parse
2851 the nickname out of the formatted nickname string. The library
2852 calls it to get the nickname from the formatted string. Since
2853 the application generally knows better the format of the nickname
2854 string it parses it instead of the library, even though library
2855 encodes the formatted string. If the callback function is not
2856 provided then the library will use the string as is. The
2857 affected file is lib/silcclient/silcapi.h.
2859 * All the nickname strings passed to the client library in
2860 commands are now expected to be formatted nickname strings.
2861 If the command does not support the formatted nickname string
2862 it will assume that the sent string is the actual nickname.
2863 Affected file lib/silcclient/command.c.
2865 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Added public key authentication support to OPER and SILCOPER
2868 commands in the client library. Affected file is
2869 lib/silcclient/command.c.
2871 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Changed the get_auth_methdod client operation to be asynchronous.
2874 It can be async if the application resolves the authentication
2875 method from the server during the negotiation. Added new
2876 SilcGetAuthMeth completion callback that the application will
2877 call after resolving the authentication method.
2879 Added function silc_client_request_authentication_method that
2880 the application can use to resolve the authentication method
2881 from the server. Added also SilcConnectionAuthRequest callback
2882 that the library will call after the server has replied. The
2883 application can call this function if it does not know the
2884 current authentication method.
2886 Affected files are lib/silcclient/client.c and
2887 lib/silcclient/silcapi.h.
2889 * The Irssi SILC client now automatically resolves the authentication
2890 method incase any configuration information is not present (and
2891 currently there never is). The affected file is
2892 irssi/src/silc/core/client_ops.c.
2894 * Fixed public key authentication from the client library.
2895 Affected file lib/silcclient/protocol.c. Changed also the
2896 protocol specification about the public key authentication in
2897 the connection authentication protocol. The actual data to be
2898 signed is now computed with a hash function before signing.
2900 * Fixed the public key authentication from the server as well.
2901 Affected file silcd/protocol.c.
2903 * Removed the mlock()'s from the memory allocation routines.
2904 Affected file lib/silcutil/silcmemory.c. The ./configure does
2905 not check anymore for the mlock(). Affected file is
2908 * Fixed USERS command in server to allow the execution of the
2909 command for private and secret channels if the client sending
2910 the command is on the channel. Affected file silcd/command.c.
2912 * Fixed silc_client_get_clients_local to return the clients
2913 count correctly. It could return wrong value. Affected file
2914 lib/silcclient/idlist.c.
2916 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2919 types. The assembler optimizations seemed not to like 64-bit
2920 data types. The assmebler optimizations thus are now enabled
2921 also for BSD systems as opposed to only enable them for Linux.
2923 * Do not check for threads at all on BSD systems. Affected
2924 file configure.in.pre.
2926 * Removed -n and -h options from the Irssi SILC Client since
2927 they are not used in silc.
2929 * Fixed the prime generation to assure that the first digit
2930 of the generated random number is not zero since our conversion
2931 routines does not like number strings that starts with zero
2932 digit. If zero digit is seen the random number is regenerated.
2933 This caused some corrupted RSA keys when the zero first digit
2934 was met. Affected file lib/silcmath/silcprimegen.c.
2936 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Fixed WIN32 configuration in the ./configure script.
2939 Fixed to include xti.h on environments that has it.
2940 Patches by Carsten Ilchmann and andrew.
2942 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Changed the silc_id_create_client_id to be collision
2945 resistant. It is now assured that there cannot be created
2946 two same client ID's. I suspect that some weird bugs in
2947 the server were actually caused by duplicate Client IDs.
2948 Affected file silcd/serverid.[ch]. A router receiving
2949 new ID now also assures and informs the sending server
2950 if the ID caused collision.
2952 * Changed the silc_id_create_channel_id to also assure that
2953 there are no collisions.
2955 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Statement about ignoring the Mutual Authentication flag when
2958 performing rekey with PFS was a bit misleading. It is ignored
2959 if it was set in the initial negotiation, it cannot be even
2960 set in the rekey. Fixed in the ke-auth draft. Started the
2961 new versions of the protocol drafts in the doc/.
2963 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Fixed a bug in silc_client_command_identify_save when saving
2966 new channel information. The channel name was no duplicated
2967 and caused crash on exit. Affected file is
2968 lib/silcclient/command_reply.c.
2970 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Fixed the getkey command handling in the server. Send just
2973 empty OK reply to the sender if the key could not be fetched
2974 (but everything else was ok, like the key just was not available).
2975 Changed the public key parameter to optional in the protocol
2976 specs so that empty OK reply can be sent. Affected file
2979 Added a message to Irssi SILC client to tell to user if the
2980 server did not return a public key.
2982 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * Fixed a channel key regeneration bug. It registered new
2985 timeout tasks exponentially until all system resources were
2986 used. Affected file silcd/server.c.
2988 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Added the SILC Document generator to the scripts/silcdoc.
2991 It can be used to generate the Toolkit Reference Manual out
2992 of the source tree. Internally it will also use the RoboDoc
2993 generator now imported in util/robodoc.
2995 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Added couple of return's in rekey protocol if error orccurred
2998 during the protocol. The execution must be terminated.
2999 Affected file silcd/protocol.c. Also, terminate the protocol
3000 always with timeout.
3002 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * The client's Client ID was created initally from the wrong
3005 nickname (it could have been in format nick@host) in the
3006 silc_server_new_client. Affected file silcd/packet_receive.c
3008 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Added some SILC_LOG_ERROR's to various error conditions
3011 if client could not be added to ID cache. Affected files
3012 silcd/packet_receive.c and silcd/server.c.
3014 * When client's sock->user_data is freed, NULL also the
3015 client->router and client->connection pointers. Added check
3016 for these pointers being NULL to various places around the
3017 code. Affected file silcd/server.c.
3019 * Added client->data.registered == TRUE checks to various
3020 places around the code to assure that unregistered client's
3021 are not handled when it is not allowed. Affected file
3024 * Added `bool registered' fields to all
3025 silc_idlist_[server|client]_get_* routines to indicate whether
3026 the fetched client needs to be registered or not. Affected
3027 file silcd/idlist.[ch].
3029 * Add your own entry as registered to the ID cache in the
3030 server. Affected file server.c.
3032 * Fixed a bug in silc_server_new_server. The SilcServer was
3033 set as the new server's context instead of SilcServerEntry.
3034 This naturally caused some weird bugs.
3036 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Do not delete the channel rekey task when adding it
3039 for in silc_server_create_channel_key.
3041 * Changed the silc_server_create_channel_key to return
3042 TRUE or FALSE to indicate the success of the channel key
3045 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Fixed MSVC++ project files and added missing files to
3048 Makefiles under win32/.
3050 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Do not add TCP_NODELAY flag if the operating system
3053 does not have it defined. Affected files are
3054 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3056 * Fixed buffer overflow from Irssi SILC Client. Affected
3057 file irssi/src/fe-common/core/themes.c.
3059 * Fixed double free in client library in the file
3060 lib/silcclient/client.c when disconnecting from server.
3062 * Applied double free patch from cras to Irssi SILC client.
3063 Affected files irssi/src/core/[modules/expandos].c
3065 * Fixed the disconnection handling to Irssi SILC Client.
3066 The application must call silc_client_close_connection
3067 in ops->connect client operation in case of failure of
3068 the connection. Affected file is
3069 irssi/src/silc/core/client_ops.c.
3071 * Do not set sock->protocol to NULL in the function
3072 silc_client_close_connection after executing the protocol's
3073 final callback since the sock might not be valid anymore.
3074 Affected file lib/silcclient/client.c.
3076 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Do not enable SILC_THREADS if the linking with libpthread
3079 did not happen. Affected file configure.in.pre.
3081 * Added notion to protocol specification that server must
3082 verify the sent authentication payload with CMODE when
3083 setting the channel founder key. Implemented it to the
3084 server. Affected file silcd/command.c.
3086 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Added _EXTRA_DIST SILC distribution variable to the
3089 distributions file. It is used to conditionally add extra
3090 files or directories to the specific distribution. Affected
3091 files ./prepare, Makefile.am.pre and distributions.
3093 Removed the `_' from the start of the distribution names.
3096 * Added README.WIN32 for instructions to compile the Toolkit
3099 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Fixed a double free in disconnection in the server. Affected
3102 file is silcd/server.c.
3104 * Fixed the lib/silcske/groups.c to work now also with GMP
3105 MP library. The string conversion did not work when using
3106 specific base and the base is indicated in the string as well.
3108 * Created win32/ directory which now includes MSVC++ specific
3109 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3110 It will appear only in the toolkit distribution
3112 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Changed the key material distribution function in case when
3115 the hash output is too short. The data is now concatenated
3116 a bit differently than it used to. Made the change to the
3117 SKE protocol specification.
3119 * Added better GMP detection to configure.in.pre. A patch
3122 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Fixed a minor bug in SKE that might cause some problem on
3125 some platforms. Affected file lib/silcske/silcske.c.
3127 * Added the cookie checking for initiator in the SKE. It checks
3128 that the responder returns the sent cookie unmodified. The
3129 affected file is lib/silcske/silcske.c. Added new SKE
3130 error type INVALID_COOKIE that can be sent during the
3131 negotiation. Fixed some memory leaks as well.
3133 * Added the "invalid cookie" error message to Irssi SILC client's
3136 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Added `task_max' field to the SilcClientParams to indicate
3139 the maximum tasks the scheduler can handle. If set to zero,
3140 default values are used. Affected file lib/silcclient/silcapi.h.
3142 * Fixed memory leaks in silc_client_close_connection. Affected
3143 file lib/silcclient/client.c.
3145 * Added silc_client_del_client_entry to client library to free
3146 all memory of given client entry. Affected file is
3147 lib/silcclient/idlist.[ch].
3149 * Added new functions silc_client_del_channel and
3150 silc_client_del_server to delete channel and server entries.
3151 Affected file lib/silcclient/[silcapi.h/idlist.c].
3153 * Removed silc_client_del_client_by_id from silcapi.h.
3155 * Fixed the INFO command to return the server's own info
3156 correctly when querying by Server ID. Affected file is
3159 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * Removed the non-blocking settings in WIN32 code in the
3162 silc_sock_[read/write] and added SleepEx instead. Affected
3163 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3164 of input data is now checked with FIONREAD and ioctlsocket.
3166 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3168 * Call silc_schedule_task_del_by_context in the
3169 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3170 Affected file lib/silccore/silcprotocol.c.
3172 * Call silc_protocol_cancel for active protocols in the
3173 silc_server_close_connection if the funtion
3174 silc_server_free_sock_user_data has not been called.
3175 Affected file silcd/server.c.
3177 * Generic tasks cannot be deleted using the del_by_fd
3178 task deleting function since generic tasks does not match
3179 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3181 * Added a notion to SILCOPER help file that the SILCOPER works
3182 only on router server, not on normal server.
3184 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3186 * Added for WIN32 support for the new scheduler as well.
3187 Affected file lib/silcutil/win32/silcwin32schedule.c.
3189 * Fixed the SHA1 implementation to work on various platforms.
3191 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3193 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3194 API. It is part of the scheduler now. Everything else is
3195 as previously but some functions has changed their names.
3196 Checkout the lib/silcutil/silcschedule.h for the interface.
3197 Updated all applications to use the new interface. Affected
3198 files are lib/silcutil/silcschedule.[ch].
3200 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Found a bug in the SKE implementation. The HASH value,
3203 specified by the protocol, was not computed correctly. The
3204 public key of the responder was not added to the computation
3205 even though it is mandatory. Affected file lib/silcske/silcske.c.
3206 This unfortunately causes incompatibilities with older
3207 clients and servers.
3209 * Added WIN32 specific network init and uninit functions:
3210 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3211 the Winsock2. Affected file lib/silcutil/silcnet.h and
3212 lib/silcutil/win32/silcwin32net.c.
3214 * Set the socket always to nonblocking mode on WIN32 after
3215 reading data or writing data. Affected file is
3216 lib/silcutil/win32/silcwin32sockconn.c.
3218 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Fixed various compilation problems under WIN32. Affected
3221 files lib/silcutil/win32/silcwin32thread.c and
3222 lib/silcutil/win32/silcwin32schedule.c.
3224 * Removed all _internal.h #includes from public header
3225 files. Internal headers must never be included from
3228 Removed also the lib/silcske/payload_internal.h file.
3230 * All include files that may be needed (public and some others
3231 included by the public headers) by application developers are
3232 now copied to the ./includes directory. It does not copy any
3233 internal headers. Affected file Makefile.defines.pre and all
3234 Makefile.am's under lib/ and subdirs.
3236 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Do not change the ~/.silc directory's permissions automatically.
3239 Affected file irssi/src/silc/core/clientutil.c.
3241 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3243 * Do not cancel the protocol in silc_server_close_connection
3244 it might cause recursion. Now cancelled in the function
3245 silc_server_free_sock_user_data. Affected file silcd/server.c.
3247 * Fixed the silc_server_remove_clients_by_server to regenerate
3248 the channel keys correctly finally. Added also new function
3249 silc_server_remove_clients_channels to actually do it.
3250 Affected file silcd/server.c.
3252 * Fixed the silc_server_new_channel to not crash by giving
3253 wrong router to the new channel. Affected file is
3254 silcd/packet_receive.c.
3256 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3259 which is given as argument to the silc_client_alloc now.
3260 It can be used to configure the client and set various parameters
3261 that affect the function of the client.
3263 * The USERS command in server did not check whether the channel
3264 is private or secret. Affected file silcd/command.c.
3266 * Added new argument to the USERS command in protocol specification.
3267 The USERS command now can take the channel name as argument
3268 as well. Added support for this in client and server and
3269 updated the protocol specs.
3271 * Completed the GETKEY command in client. It can be now used
3272 to fetch also servers public key not only some clients.
3273 Affected files lib/silcclient/command[_reply].c.
3275 * Added silc_client_get_server to return server entry by the
3276 server name. Affected files lib/silcclient/silcapi.h and
3279 * Redefined the IDENTIFY command in protocol specification to be
3280 more generic. It now can be used to query information about
3281 any entity in the SILC Network, including clients, servers and
3282 channels. The query may be based either the entity's name
3283 or the ID. Added support for this in both client and server.
3285 Affected files silcd/command.c and lib/silcclient/command.c
3286 and command_reply.c.
3288 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3289 the _from_client and _from_server functions. Affected file
3292 * Added silc_client_get_channel_by_id_resolve to the file
3293 lib/silcclient/silcapi.h to resolve channel information by
3294 its ID. Added also silc_client_get_channel_by_id that
3295 does not resolve it from the server.
3297 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Added SilcServerEntry context into the client library
3300 to represent one server. The INFO command now allocates
3301 these to save the resolved server info. For now on the
3302 client library will also keep information about servers,
3303 connected and resolved with INFO.
3305 The INFO command now allocates the SilcServerEntry context
3306 and saves the server info there. The COMMAND_REPLY in
3307 the INFO now returns the parameters to application in
3308 same order as defined in the protocol specification.
3310 The entries are cached in the client->server_cache.
3312 * The INFO command is now issued after received the Client ID
3313 from the server. Affected file lib/silcclient/client.c.
3315 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3316 to the application as the mode changer might be server.
3317 It is guaranteed that NULL is not returned anymore to the
3318 application. Affected file lib/silcclient/client_notify.c.
3320 The ID Type is now also passed to the application so that
3321 it can check whether the returned entry is SilcClientEntry
3324 Added new function silc_client_get_server_by_id to return
3325 the server entry by ID. Affected files are the
3326 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3328 * Do not create the channel in the Irssi SILC Client when issuing
3329 the JOIN command but when received the sucessful JOIN command
3330 reply. Otherwise the channel might get created even though we
3331 could not join it. The Affected file is
3332 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3334 * Fixed a channel joining bug in router. The router must also
3335 check the channel modes, invite and ban lists etc. when serving
3336 the JOIN command sent by normal server. Affected file is
3337 silcd/command.c. The router now resolves the client's
3338 information from the server who sent the JOIN command if it
3339 does not know it, and processes the JOIN command only after
3342 * Changed the SilcCommandCb to take new argument; void *context2.
3343 Affected file lib/silccore/silccommand.h
3345 The second argument in the command callbacks in the server now
3346 includes the SilcServerCommandReplyContext if the command was
3347 called as pending command callback from the command reply.
3348 Otherwise it is NULL. When called as pending the status of the
3349 command reply will be checked and if it was erronous the
3350 error will be sent to the original sender of the command.
3351 This way the client always receives the error messages even
3352 though the server was actually the one who received the error
3353 when it resent the command to router, for example. Affected
3354 files silcd/command[_reply].[ch].
3356 * Fixed sending WHOWAS command's error message to client if
3357 the requested client could not be found. It was missing.
3360 * Changed the CMODE and CUMODE commands reply arguments in the
3361 protocol specification. The Channel ID is now sent in both
3362 of the commands to identify the channel. Implemented this
3363 new feature to the client and server. Affected files
3364 lib/silcclient/command_reply.c and silcd/command.c.
3366 * Made better checks for invite and ban lists in the JOIN
3367 command in server. Affected file silcd/command.c.
3369 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3371 * The server now performs the incoming host IP/DNS lookup
3372 using the silc_socket_host_lookup and thus does not block
3373 the server anymore. Affected file silcd/server.c.
3375 * Completed the multi-thread support for SILC Scheduler in
3376 the lib/silcutil/silcschedule.c.
3378 * Fixed the configure.in.pre to detect the pthread correctly
3381 * Fixed a deadlock in silc_task_queue_wakeup in the file
3382 lib/silcutil/silctask.c.
3384 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Added new function silc_schedule_wakeup that is used in
3387 multi-threaded environment to wakeup the main thread's
3388 schduler. It needs to be used when a thread adds a new task
3389 or removes a task from task queues. After waking up, the
3390 scheduler will detect the task queue changes. If threads
3391 support is not compiled in this function has no effect.
3392 Implemented the wakeup mechanism to both Unix and WIN32
3393 systems. Affected files are lib/silcutil/silcschedule.[ch],
3394 lib/silcutil/unix/silcunixschedule.c and the
3395 lib/silcutil/win32/silcwin32schedule.c.
3397 * Added new function silc_task_queue_wakeup to wakeup the
3398 scheduler by the specified task queue. Affected file
3399 lib/silcutil/silctask.[ch].
3401 * The silc_socket_host_lookup_start now wakes up the scheduler
3402 after adding the timeout task. Affected file is
3403 lib/silcutil/silcsockconn.c.
3405 * The silc_socket_host_lookup is synchronous now if the threads
3406 support is not compiled in. However, the callback is still
3407 called asyncronously through the scheduler, anyway. Affected
3408 file lib/silcutil/silcsockconn.c.
3410 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * Added new function silc_socket_host_lookup to perform
3413 asynchronous IP and FQDN lookups for the socket connection.
3414 Affected files lib/silcutil/silcsockconn.[ch].
3416 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3418 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3419 that may or may not compile the mutex support in.
3421 Changed the silc_mutex_alloc interface. It allocates the
3422 mutex now to the sent pointer and returns TRUE or FALSE.
3424 Affected file lib/silcutil/silcmutex.h.
3426 * Wrote the SILC Task Queue interface to support multi-threads.
3427 Affected file lib/silcutil/silctask.[ch].
3429 * Wrote the SILC Scheduler to support multi-threads. Affected
3430 file lib/silcutil/silcschedule.c.
3432 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3435 in lib/silcutil/win32/.
3437 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3439 * Defined SILC Mutex API and SILC Thread API and implemented
3440 them for Unix. Affected files are
3441 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3442 lib/silcutil/unix/silcunixmutex.c and
3443 lib/silcutil/unix/silcunixthread.c.
3445 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Fixed the silc_server_remove_clients_by_server's channel
3448 key re-generation. The hash table handling was incorrect
3449 and would not work with many channels. Affected file is
3452 * Fixed some memory leaks around the server code.
3454 * Rewrote the silc_server_get_users_on_channel to support IPv6
3455 based Client ID's. Affected file silcd/server.c.
3457 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3458 specification. However, a separate document must be written
3459 to define the detailed signing procedure and the payload
3460 associated with the flag. Defined the flag to the
3461 lib/silccore/silcchannel.h as well.
3463 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3465 * Changed the dynamic tables to static size tables in the
3466 lib/silccrypt/silchmac.c.
3468 * Removed GCC dependencies from the code. A patch by cras.
3470 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Do not show the error "Error receiving packet bla bla"
3473 in server if it really was not an error (-2 means that reading
3474 is pending). Affected file silcd/server.c.
3476 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Fixed a possible crash in silc_server_remove_clients_by_server
3479 in silcd/server.c. Fixed there also some memory leaks.
3481 * Fixed the silc_idlist_replace_client_id. It could replace
3482 wrong key in the hash table. Affected file silcd/idlist.c.
3484 * Do not check whether there are global users on the channel
3485 if the channel->global_users is FALSE. Affected functions
3486 silc_server_remove_from_one_channel and
3487 silc_server_remove_from_channels in silcd/server.c. Also,
3488 do not check if the removed client is local as we can be
3489 sure that global client was not removed from the channel
3490 and checking for global users is not needed.
3492 * The silc_server_remove_clients_by_server now re-generates
3493 the channel keys correctly for those channels that had
3494 clients removed from them. Affected file silcd/server.c.
3496 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * Found the reason of random crashes in the server. We weren't
3499 ignoring the SIGPIPE signal (which can be sent in write())
3500 and it crashed the server. Affected file silcd/silcd.c.
3502 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Assure that sock->user_data is not NULL in the function
3505 silc_server_packet_send in silcd/packet_send.c.
3507 * Disconnect the remote connection if it could not be added
3508 to any ID lists in the server. The affected file is
3511 * Check in silc_server_packet_send[_real/dest] that the
3512 socket is not disconnecting and ignore the data if it is.
3513 Affected file silcd/packet_send.c.
3515 * Define inline to __inline on native WIN32 compilation.
3516 Affected file includes/silcwin32.h.
3518 * Added some explicit type casts for inline code since MSVC
3519 require them. Affected files lib/silcutil/silcbuffer.h,
3520 lib/trq/silcdlist.h and lib/trq/silclist.h.
3522 * Print warning in log files from now on if the packet
3523 decryption fails. Affected file silcd/server.c.
3525 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Changed the `say' client operation's interface to accept
3528 new `type' argument to indicate the type of the message sent
3529 by the library. The application may filter the library's
3530 messages according the type. The affected file is the
3531 lib/silcclient/silcapi.h.
3533 * Added two new functions to lib/silcclient/silcapi.h:
3534 silc_client_del_client and silc_client_del_client_by_id.
3535 Affected file lib/silcclient/idlist.c.
3537 * Moved the clientincludes.h from includes/ to silc/ and
3538 serverincludes.h from includes/ to silcd/.
3540 * The modes for the CMODE and CUMODE are now passed as
3541 uint32 for application with COMMAND_REPLY. The affected
3542 file is lib/silcclient/command_reply.c.
3544 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * /WHOIS without arguments shows client's own information.
3547 Affected file lib/silcclient/command.c.
3549 * Changed PING to not accept any arguments. The specs
3550 says that client can ping only the connected server so
3551 requiring an argument is not needed. Affected file is
3552 lib/silcclient/command.c.
3554 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3556 * Fixed a fatal bug in private message sending and reception
3557 encryption and decryption when using private message keys.
3558 The implementation was incorrect and did not follow the
3559 specification. It causd that some of the message were
3560 lost since it did not use the sending and receiving keys
3561 as the protocol suggests. This has been fixed and will cause
3562 incompatibilities with older clients when sending private
3563 message encrypted with private message keys. Affected files
3564 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3565 and various other in Irssi SILC Client.
3567 Added `responder' boolean argument to the functions
3568 silc_client_add_private_message_key[_ske] to indicate when
3569 the key is added as responder or initiator of the key
3572 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Removed the silc_ske_check_version function and created
3575 a SilcSKECheckVersion callback. Added also a function
3576 silc_ske_set_callbacks that is now used to set all SKE
3577 callbacks. The callback functions are not given to
3578 the SKE functions anymore, but this function is used to
3581 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3583 * Added `silc_version' argument to the silc_client_alloc
3584 to define the version of the application for the library.
3585 The library will use the version string to compare it
3586 against the remote host's (usually a server) version
3587 string. Affected file lib/silcclient/silcapi.h
3589 * Added the KE protocol context to Key Agreement context
3590 in client library so that we can abort the SKE if it
3591 is in process when we get timeout. Affected file is
3592 lib/silcclient/client_keyagr.c.
3594 * Do not resolve the client ID forever if it returns in the
3595 first time that such client does not exist. This was done
3596 for example with private message. Affected file is
3597 lib/silcclient/client_prvmsg.c.
3599 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * Do not add regex.h for WIN32. The affected file
3602 includes/silcincludes.h.
3604 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3605 not work yet 100%. It generates the DLL's automatically
3606 when compiling with --with-win32 under cygwin.
3608 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * lib/contrib/regex.c is not compiled on WIN32.
3612 * Added silc_net_get_socket_opt function to the
3613 lib/silcutil/silcnet.h.
3615 * Added includes/silcwin32.h for WIN32 specific includes
3618 * Do not use ptime structure or any of the posix process
3619 functions on WIN32 in lib/silccrypt/silrng.c.
3621 * Added silc_gettimeofday to provide generic function
3622 for struct timeval on all platforms. Added the function
3623 to lib/silcutil/silcutil.h.
3625 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3627 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3628 library as they clearly belong there. As a plus side we
3629 can make the actual socket connection routines platform
3632 Added also new generic function silc_socket_read and
3633 silc_socket_write (that used to be silc_packet_[read/write].
3634 The implementation of these are platform specific.
3636 * Added WIN32 specific routines of silc_socket_[read/write]
3637 to lib/silcutil/win32/silcwin32sockconn.c.
3639 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3641 * Added preliminary support for native WIN32 compilation under
3642 cygwin (using the -mno-cygwin option for GCC) to the
3643 ./configure.in.pre. The --with-win32 now prepares the
3644 compilation for native WIN32.
3646 * Rewrote the SILC Scheduler interface in the file
3647 lib/silcutil/silcschedule.h. The scheduler is now context
3648 based and does not have anymore any global static scheduler.
3649 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3650 and created lib/silcutil/win32 directory for WIN32 based
3653 * Added Unix specific network routines to the
3654 lib/silcutil/unix/silcunixnet.c and the old
3655 lib/silcutil/silcnet.c includes now only generic routines.
3657 Added WIN32 specific network routines to the
3658 lib/silcutil/win32/silcwin32net.c.
3660 * Added Unix specific utility functions from the
3661 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3663 * Added WIN32 SILC Scheduler to the file
3664 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3667 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3669 * Do not handle JOIN notify in the server if the target client
3670 is not registered (idata->registered == FALSE). The affected
3671 file is silcd/packet_receive.c.
3673 * Update the nickrec->founder in event_cumode in the Irssi SILC
3674 client. Affected file irssi/src/silc/core/silc-channels.c.
3676 * Fixed the CUMODE_CHANGE notify handling in the server when
3677 server and router are announcing their clients on channels.
3678 Now the mode changes are saved and notified correctly. The
3679 affected file is /silcd/packet_receive.c.
3681 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3682 They really did not replace the cache entry in the ID Cache.
3683 Now they do that. Affected file silcd/idlist.c.
3685 * Fixed the KICK notify handling in the Irssi SILC client to
3686 update the channel records so that the kicked client does not
3687 appear to be on the channel. The affected file is
3688 irssi/src/silc/core/silc-channels.c.
3690 * Always update the conn->current_channel when executing command
3691 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3693 * Fixed the KILL notify handling in Irssi SILC client to remove
3694 the killed client on all channels.
3696 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Fixed the silc_parse_command_line to remove extra spaces
3699 from the start and end of the arguments. Affected file is
3700 lib/silcutil/silcutil.c.
3702 * Cancel and free any active protocol in the function
3703 silc_server_close_connection. Affected file silcd/server.c.
3705 * Cancel and free any active protocol in the function
3706 silc_client_close_connction. Affected file is
3707 lib/silcclient/client.c.
3709 * Do not execute the KILL command for clients that are in
3710 history (ie. they are not in the network). Affected file is
3713 * Fixed KILL notify handling, client does not crash anymore.
3714 Affected file irssi/src/silc/core/silc-channels.c.
3716 * Reduced the default packet buffer size from 2048 to 1024 in
3717 lib/silccore/silcpacket.c.
3719 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3720 counter to the SKE context that is incresed when the SKE library
3721 performs async operation outside the library. If the outside
3722 process frees the SKE context and FREED status will be set
3723 and the library will detect after the sync operation that the
3724 libary is freed. The affected files are
3725 lib/silcske/silcske[_status].[ch].
3727 * Resolve the client entry information in the function
3728 silc_client_channel_message to assure that NULL pointer is not
3729 passed as client entry to the application. */
3731 * Fixed the task timeout calculation to assure that there is
3732 never negative timeouts. The affected file is
3733 lib/silcutil/silcschedule.c.
3735 * Fixed the channel user mode notification sending in server.
3736 It was sent point-to-point to the router (or to server by router)
3737 but it needs to be destined to a channel. The routines now
3738 supports sending the channel user mode notifys to the channels
3739 when announcing clients and channels. Affected files are
3740 silcd/server.c and silcd/packet_receive.c.
3742 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3743 It did not actually replace the old channel entry in the cache.
3744 Affected file lib/silcclient/client_notify.c.
3746 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Fixed a possible crash in silc_packet_send_prepare. It now
3749 assures always that there is enough space in the buffer and
3750 at the tail area of the buffer (for MAC).
3752 Fixed the inbound buffer reallocation in silc_packet_read.
3753 It was old code and did not handle the reallocation correctly.
3756 The affected file is lib/silccore/silcpacket.c.
3758 * Fixed buffer overflow in silc_parse_nickname in the file
3759 lib/silcutil/silcutil.c.
3761 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * make install generates new server keys only if there is not
3766 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3769 Added check that if the NOREPLY is set then we will not send
3770 the away message. This avoids infinite loop of away messages
3771 if both clients are away. The affected file is
3772 lib/silcclient/client_prvmsg.c.
3774 * Fixed client crash if /NICK was given without arguments.
3775 Affected file lib/silcclient/command.c.
3777 * Server does not send the invite list in INVITE command back
3778 to the client if the list was not altered. Added this notion
3779 to the protocol spec as well. Affected file silcd/command.c.
3781 Fixed possible crash in INVITE command by checking the
3782 value of silc_server_get_client_route command.
3784 * Fixed the INVITE notify type handling. The arguments are now
3785 taken in correct order and client does not crash. The affected
3786 file is irssi/src/silc/core/silc-channels.c.
3788 Removed the "Inviting xxx to channel" message from the
3789 client library away and let the application handle it.
3790 Affected file lib/silcclient/command.c. Added that message
3791 to Irssi SILC client's message formats.
3793 * Fixed CMODE command crash in client. It now checks the
3794 amount of arguments correctly and does not crash. The affected
3795 file is lib/silcclient/command.c.
3797 * Do not create new channel automatically in silc_channels_join
3798 but check whether the channel by that name already exists.
3799 Affected file irssi/silc/core/silc-channels.c.
3801 * Do not send the SERVER_SIGNOFF to router if the disconnected
3802 entity was the router. Affected file silcd/server.c.
3804 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3805 SILC client as it was missing from there.
3807 Added the handling of the KICK notify to the Irssi SILC client
3808 as it was missing. Added "you have been kicked" message to
3809 Irssi SILC client's message modules formats.
3811 Added the handing of the KILL notify to the Irssi SILC client
3812 as it was missing. Added the kill message module formats
3815 The affected file is irssi/src/silc/core/silc-channels.c.
3817 * The router did not save the channel mode the server announced.
3818 Affected file silcd/packet_receive.c.
3820 * Fixed a possible crash in INFO command in server. If the
3821 server did not provide the server info it crashed. Affected
3822 file silcd/command.c.
3824 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Fixed the GETKEY command in the server to check also the
3827 global list. Otherwise the GETKEY would not work correctly
3828 in normal SILC server. Affected file silcd/command.c.
3830 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Fixed GETKEY crash, it crashed if the command did not succseed.
3834 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3837 is now real and not just an macro interface to GMP.
3839 Removed the entire GMP from the source tree and imported new
3840 NSS MPI library instead. Reason for removing GMP is that it is
3841 extremely large and compiles extremely slow. The NSS MPI
3842 is only a few files and compiles in less than 10 seconds.
3843 The speed is also about the same as GMP. The MPI is imported
3844 to lib/silcmath/mpi.
3846 If the system has GMP installed we will still use the GMP.
3847 If it is not then the NSS MPI will be compiled.
3849 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Merged a long nickname (127 characters long) crash bugfix from
3852 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3854 * Merged a freed memory reference bugfix from Irssi CVS tree.
3855 Affected file irssi/src/core/commands.c.
3857 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Added the server's public key sving and verification to the
3860 server when performing the SKE. This was missing and the
3861 remote server's (or router's) public key was accepted without
3862 checking whether we have it previously or trust it at all.
3863 Affected file silcd/protocol.c.
3865 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Check in the silc_server_timeout_remote if protocol is active
3868 and make sure that the protocol's final callback is called so
3869 that all memory if freed. Affected file silcd/server.c.
3871 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * silc_server_whois_send_reply crashed the server if the nickname
3874 was 127 characters long. Affected file silcd/command.c.
3876 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Added sanity check to the silc_server_new_client. If the hostname
3879 is provided inside username then check that the provided hostname
3880 really is the same as the resolved one. If the hostname was not
3881 resolved then check it from the public key. Affected file is
3882 silcd/packet_receive.c.
3884 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3885 if the server disconnected us and the connection is not valid
3886 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3888 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3889 the library to the lib/silcutil/silcutil.[ch].
3891 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Close log file after open. Affected file
3894 lib/silcutil/silclog.c.
3896 * Check whether sock == NULL in silc_client_send_packet and return
3897 if it is. Affected file lib/silcclient/silcclient.c.
3899 * Check rec->entry == NULL in the Irssi SILC Client before
3900 sending the channel message. Affecte file is
3901 irssi/src/silc/core/silc-servers.c.
3903 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Merged a splitted window bugfix from Irssi CVS tree. The
3906 affected file is irssi/src/fe-text/textbuffer-view.c.
3908 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3909 It did not print nickname.
3911 * Improved the distributions system a bit.
3913 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3916 irssi/src/fe-text/gui-window.c.
3918 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3919 to in-active server. The affected file is
3920 irssi/src/silc/core/client_ops.c.
3922 * Resolve the client in USERS command reply if the entry does
3923 not have username resolved. The affected file is
3924 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3925 command to WHOIS command to really resolve stuff. The USERS
3926 is not used any more in any critical section so WHOIS can
3927 be used even though it might be slower than IDENTIFY.
3929 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3932 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3934 * Changed the protocol API a bit more consistent in the
3935 lib/silccore/silcprotocol.[ch].
3937 * Changed the following headers to ROBODoc format:
3939 lib/silccore/silcpayload.h
3940 lib/silccore/silcprotocol.h
3941 lib/silccore/silcsockconn.h
3943 All core library headers are now formatted.
3945 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Fixed a bug in Irssi SILC client; do not show that you are
3948 server/router operator if you really are not. Affected file is
3949 irssi/src/silc/core/client_ops.c.
3951 * Renamed silc_command_free_payload to silc_command_payload_free.
3952 Affected file lib/silccore/silccommand.h
3954 * Added silcmath.h to include the prototoypes of various routines
3955 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3958 * Changed the following headers to ROBODoc format:
3960 lib/silccore/silcchannel.h
3961 lib/silccore/silccommand.h
3962 lib/silccore/silcid.h
3963 lib/silccore/silcidcache.h
3964 lib/silccore/silcmode.h
3965 lib/silccore/silcnotify.h
3966 lib/silccore/silcpacket.h
3967 lib/silcmath/silcmath.h
3969 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added checking to the server code not to start the server if
3972 ciphers and stuff are not configured properly. Affected files
3973 silcd/serverconfig.[h] and silcd/server.c.
3975 * Changed the layout of the header files of the public interfaces
3976 in the SILC libraries. The new layout supports ROBODoc
3977 documentation tool (and some others) so that it is easy to create
3978 a library reference manual. All the other headers and source
3979 code must still follow the CodingStyle document. Also source
3980 code must not include these ROBODoc stuffs, only the headers.
3981 Furthermore, all public interface headers must now be named
3982 by using `silc' prefix, example: silcapi.h, silccipher.h.
3983 Some files were renamed due to this. All the other headers
3984 must not be used as public interfaces. I will update the
3985 CodingStyle document later. Changed following headers, so far:
3987 lib/silcclient/silcapi.h
3988 lib/silccore/silcauth.h
3989 lib/silccore/silcprivate.h
3990 lib/silccrypt/silcdh.h
3992 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Removed silc_client_packet_send_flush from the client library
3997 as it is not needed. Affected file lib/silcclient/client.[ch].
3999 * Added printing of message of unresolved authentication method
4000 to the Irssi SILC client. Added it to the module formats.
4001 Removed the same message from the client library.
4003 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added new distribution feature, DISTLABEL. Every distribution
4006 can define own preprocessor label that can be used in the
4007 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4008 file distributions, acconfig.h.pre and prepare.
4010 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Added Makefile.defines_int to include the actual definitions
4013 for Makefile.defines.in. Tested the new distribution system,
4014 created distributions and tested installation.
4016 * Added AWAY message printing to the Irssi SILC client. Added
4017 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4019 * Added SCONNECT command to call the SILC's CONNECT command.
4020 Cannot use CONNECT directly since Irssi uses that internally.
4021 Affected file irssi/src/silc/core/silc-servers.c.
4023 Added ACTION local command. It is same as ME command but takes
4024 the channel as mandatory argument.
4026 Rewrote some of the Irssi's help files to suite for SILC
4029 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Added Makefile.defines[.in] that should for now on be included
4032 in all Makefile.am file in the source tree. That file includes
4033 all common compilation definitions for SILC source tree.
4035 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Minor changes to the ./prepare script to change the package
4038 name according the distribution name to the configure.in.
4040 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Created new distribution system. Added file `distributions'
4043 that defines all the distributions that can be created out of
4044 the SILC source tree. The ./prepare script now reads that
4045 file to determine how to prepare the distributions. The
4046 first argument to the ./prepare is the name of the distribution
4047 and second is the version of the distribution. If given
4048 without arguments it creates the default (toolkit) distribution
4049 with the default version (defined in ./prepare).
4051 All Makefile.am files that are subject to the distributions
4052 are now named as Makefile.am.pre. These are ./Makefile.am
4053 and lib/Makefile.am. Others may be changed later.
4055 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Added invite list, ban list, some key management and connection
4058 error message printing to module formats in the Irssi SILC client.
4060 * Added new silc_client_set_away_message to set the away message
4061 that is back to the person who sent private message. The
4062 affected file lib/silcclient/silcapi.h and the
4063 lib/silcclient/client_prvmsg.c.
4065 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Fixed the private message sending in the Irssi SILC client,
4068 added local command KEY to the Irssi SILC client.
4070 Added key management and key agreement message formats to the
4071 irssi/src/fe-common/silc/module-formats.[ch].
4073 Added USERS (alias WHO) printing, server/router operator
4074 indication and LIST command printing to the module formats.
4076 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Fixed channel joining notify handling, cumode notify handling
4079 from Irssi SILC client.
4081 * Added SILC specific module-formats to the Irssi SILC client so
4082 that SILC specific message hilighting, colors etc is possible.
4083 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4085 Added channel mode, channel user mode, actions, notices,
4086 whois and whowas printing to the the module-formats.c.
4088 * Fixed a bug in channel deletion in the server. The channel
4089 is not left to the cache even if the channel founder auth mode
4090 is set when there are no users anymore on the channel. Affected
4091 file silcd/server.c.
4093 * The silc_net_localhost now resolves the entire hostname including
4094 the domain name. Affected file lib/silcutil/silcnet.c.
4096 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Changed the ask_passphrase client operation to be ascynchronous.
4099 It has now a completion callback and a context that the
4100 application must call after it has got the passphrase from
4101 the user. Affected files lib/silcclient/silcapi.h,
4102 lib/silcclient/protocol.c, lib/silcclient/command.c and
4105 Added SilcAskPassphrase callback that the application calls
4106 to deliver the passphrase to the library.
4108 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4109 The public key verification and especially a certificate
4110 verification is asynchronous procedure.
4112 Added new SILC_SKE_STATUS_PENDING status to indicate the
4113 request is pending and a callback will be called to finalize
4116 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4117 indicate that remote end did not send its public key (or
4118 certificate), even though we require it. Added check for this
4119 condition in the SKE. This was a security bug, now fixed.
4121 Defined new SilcSKEVerifyCbCompletion callback that is called
4122 when the verification process is completed.
4124 The affected files lib/silcske/silcske_status.h and
4125 lib/silcske/silcske.[ch].
4127 * Changed the verify_public_key client operation to be async
4128 as well. Defined SilcVerifyPublicKey callback that is used to
4129 indicate the success of the public key verification process.
4131 Changed the server and client to use the new async client
4134 * Changed the Irssi SILC client's internal scheduler to be called
4135 twice as many times as it used to be. As a result the client
4136 should be a bit faster now. Affected file is
4137 irssi/src/silc/core/silc-core.c.
4139 * Added support to Irssi SILC client of asynchronous public key
4140 verification and passphrase inquiry. Affected file is
4141 irssi/src/silc/core/silc-core.c.
4143 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Do not say "You have left channel %s" in client library.
4146 Moved it to the application. Affected files are
4147 lib/silcclient/command.c and silc/client_ops.c.
4149 * Fixed silc_client_get_clients. Command context was not
4150 duplicated and was freed memory in the callback. Affected
4151 file lib/silcclient/idlist.c.
4153 * Do not say "you are now talking..." on JOIN command in the
4154 client library. The appliation must handle it.
4156 * Do not say ".. changed topic to" in command reply in the
4157 client libary. The application must handle it.
4159 * Fixed TOPIC command sending in the client library.
4161 * Fixed a memory leak in silc_client_command_free in the file
4162 lib/silcclient/command.c.
4164 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Imported a modified version of Irssi client to the source tree.
4167 The Irssi will be used to create a new client called
4168 Irssi SILC. Imported to irssi/.
4170 Added silc_core_init_finish function to the Irssi. Affected
4171 file irssi/configure.in.
4173 A lot changes in the Makefile.ams around the irssi tree.
4175 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Do not rehash if the new size is same as the old size of the
4178 hash table, in the silc_hash_table_rehash*. The affected file
4179 lib/silcutil/silchashtable.c.
4181 * Replaced hash_table_del_by_context calls from the server
4182 (when channel->user_list and client->channels) to the
4183 hash_table_del as it is sufficient and faster.
4185 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Added silc_hash_table_list, silc_hash_table_get and the
4188 SilcHashTableList structure to provide an alternative way to
4189 traverse the hash table. The affected files are
4190 lib/silcutil/silchashtable.[ch].
4192 * Changed the server's idlist routines to use the hash table
4193 routines to optimize the code.
4195 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Replaced the client entry's `channel' list and channel entry's
4198 `user_list' list to hash tables for optimized lookup. Changed
4199 the code to use the hash table interface around the code.
4200 Affected file lib/silcd/idlist.[ch].
4202 * Added `auto_rehash' boolean argument to the function
4203 silc_hash_table_alloc to indicate whether the hash table should
4204 auto-rehash when it thinks is appropriate time. It will
4205 increase the hash table size if the there is twice as much
4206 entries in the table than the size of the table, and will
4207 decrease the size if there are twice as less entries than
4208 the size of the table.
4210 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4214 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * silc_idcache_purge_by_context deletes the entry now by context
4217 as it is supposed to do. Affected file lib/silccore/idcache.c.
4219 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4220 client is not anymore valid (WHOWAS givens the info) and not
4221 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4223 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Removed the `data' and `data_len' arguments from the ID Cache
4226 interfaces and added `name' argument. ID Cache does not handle
4227 anymore the binary data only a names associated with given ID.
4229 * When hashing a Client ID with silc_hash_id the entire ID is
4230 not hashed anymore, instead only the hash of the Client ID is
4231 hashed. This way we can access the Client ID from the cache
4232 with Client ID but with the hash of the ID (which is a hash of
4233 the nickname) as well without any difference in performance.
4235 Added also silc_idcache_find_by_id_one_ext to do one on one
4236 searching when we have the actual ID. Added also function
4237 silc_hash_client_id_compare. The affected files are
4238 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4240 * When hashing the name associated with a ID it is always done
4241 in lowercase. This way we can access the cache without worrying
4242 about case-sensitivity, even though, for example nicknames are
4245 * Fixed a bug in server with channel message sending. It put
4246 wrong ID type as destination ID. The affected file
4247 silcd/packet_send.c.
4249 * silc_idcache_del_by_context now deletes from all hash tables
4250 by context. Affected file lib/silccore/idcache.c.
4252 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Changed the client library to use the new ID Cache interface.
4255 Changes around the source tree.
4257 * Added silc_hash_table_rehash_ext to rehash with specific
4258 hash function. Affected file lib/silcutil/silchashtable.[ch].
4260 * Added silc_hash_string_compare to compare two strings in the
4261 hash table. Affected file lib/silcutil/silcutil.[ch].
4263 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added new function silc_idcache_del_by_context into the
4266 lib/silccore/idcache.[ch].
4268 * Changed the server's ID list routines to use the new ID Cache
4269 interface. Changes around the source tree.
4271 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Added silc_hash_table_del[_by_context]_ext functions in to the
4274 lib/silcutil/silchashtable.[ch].
4276 Removed silc_hash_table_find_all* routines and added new
4277 silc_hash_table_find_foreach to replace them.
4279 Added silc_hash_table_replace_ext function as extended
4280 replacing function. Separated the simple hash table interface
4281 from the extended hash table interface in the file
4282 lib/silcutil/silchashtable.h.
4284 * Fixed minor bugs and changed it to use some of the new
4285 hash table functions in lib/silccore/idcache.c
4287 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Added new function silc_hash_table_find_all to return all keys
4290 in the hash table by the specified key. As the hash table is
4291 collision resistant it also makes it possible to have several
4292 duplicate keys in the hash table. This function may be used to
4293 find all of the keys from the hash.
4295 Added user_context arguments to the SilcHashFunction,
4296 SilcHashCompare and SilcHashDestructor to deliver user specified
4299 Added new fuctions silc_hash_table_find[_all]_ext to do
4300 extended lookup with specified hash and compare functions and
4301 specified user contexts.
4303 Added new function silc_hash_table_add_ext to add the key
4304 with specified hash function and user context.
4306 Added new function silc_hash_table_foreach to traverse all
4307 entrys in the hash table. Added SilcHashForeach callback
4310 Added new function silc_hash_table_del_by_context to delete
4311 the entry only if the context associated with the key matches.
4313 Affected files are lib/silcutil/silchashtable.[ch].
4315 * Removed silc_hash_[server/client/channel]_id and added just
4316 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4317 silc_hash_id_compare to compare two ID's using as the hash table
4318 comparison function. Added also silc_hash_data to hash
4319 binary data and silc_hash_data_compare to compare it.
4321 * Removed silc_idlist_find_client_by_hash as it is not needed
4322 anymore. Affected file silcd/idlist.[ch].
4324 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4325 to use internally the SilcHashTable. The new ID Cache is a lot
4326 faster than the old one. Some of the ID Cache interface was also
4327 rewritten and obsolete and stupid functions were removed.
4329 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Added entry_count field to the SilcHashTable to keep the number
4332 of the entries in the table. Implemented the function
4333 silc_hash_table_rehash. Added new function
4334 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4336 Fixed a minor bug in silc_hash_table_free.
4338 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4339 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4340 into the lib/silcutil/silcutil.[ch].
4342 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Implemented a collision resistant hash table into the
4345 lib/silcutil/silchashtable[ch]. See the header and the source
4346 for the SilcHashTable API.
4348 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Merged dotconf version 1.0.2 into lib/dotconf.
4352 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Do not compile anything in lib/silcsim/* if the SIM support
4355 is not enabled. The tree should now compile without problems
4358 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Compiled the SILC under cygwin. Compiled and tested briefly
4361 without problems. More tests needed. The SIMs didn't compile
4364 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4366 * Fixed possible crash in silc_get_username in the
4367 lib/silcutil/silcutil.c.
4369 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Fixed a va_arg in silc/client_ops.c.
4373 * Oops, RC5 routines were named AES and caused some problems
4374 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4376 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Added new SilcIDIP structure into the lib/silccore/id.h and
4379 replaced the old `ip' fields from all SILC ID's to that type.
4380 This is a step towards IPv6 support.
4382 The silc_id_get_len takes now the ID as an extra argument.
4383 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4384 both IPv4 and IPv6 based ID's.
4386 The affected files are lib/silccore/id.[ch] and other files
4387 around the tree using these routines.
4389 * Removed the ID length arguments in server from various
4390 silc_server_send_notify_* routines -> they are not needed
4393 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed memory leak in silc_encode_pem_file in the file
4396 lib/silcutil/silcutil.c.
4398 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Check minor version as well in the SKE. Affected files are
4401 silcd/protocol.c and lib/silcclient/protocol.c.
4403 * Added --identifier option to the server so that an identifier
4404 can be when creating the public key for the server. Affected
4405 file is silcd/silcd.c.
4407 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4408 lib/silccrypt/silcpkcs.c.
4410 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Register default ciphers and stuff when using -C option with
4413 the server. Affected file sildc/silcd.c.
4415 * Put back the servers public key filename format, it is better
4416 than the new one. For now, the client keys are saved with the
4417 new filename format. The affected file silc/client_ops.c.
4419 * Implemented the Cipher API for the rest of the ciphers that
4420 did not implement it or implemented it the wrong way.
4422 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Register default ciphers and stuff when using the -S option
4425 in the client. Affected file silc/silc.c. Same also when
4426 creating new key pair with -C option.
4428 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Fixed the silc_verify_public_key client operation function to
4431 save the public keys differently. The fingerprint is now
4432 used as filename and not the hostname. This way also the
4433 client keys are saved uniquely and not with hostnames. The
4434 affected file is silc/client_ops.c.
4436 * Trimmed the silc_hash_fingerprint function to remove extra
4437 whitespaces from the end of the fingerprint. The affected
4438 file is lib/silccrypt/silchash.c.
4442 * Added silc_cipher_register_default function to register all
4443 default ciphers. It can be used when configuration files
4444 does not exist and the application does not want any specific
4445 ciphers in any specific order.
4447 The SilcDList is now used as silc_cipher_list dynamically
4448 allocated cipher list. Removed the static list all together
4449 and now all ciphers must be allocated to the dynamic list.
4450 The silc_cipher_alloc routine was changed to check only the
4453 All silc_cipher_* routines that used to return int returns
4456 The affected files lib/silccrypt/silccrypt.[ch].
4458 * The same thing was done to silc_hash_* as for silc_cipher_*
4459 routines. Affected files lib/silccrypt/silchash.[ch].
4461 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4462 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4463 Added also silc_pkcs_[un]register[_default] functions.
4464 Removed the data_context from the PKCS API.
4466 * Added silc_hmac_register_default function to register default
4467 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4468 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4469 to unregister all hmacs at once.
4471 * Register the default ciphers, hash functions, PKCSs and HMACs
4472 if client's configuration file does not exist. The affected
4475 * The client did not load the hash functions from the SIM
4476 modules at all. Added support for this. Affected file is
4477 silc/clientconfig.c.
4479 * When decoding public key with silc_pkcs_public_key_decode, check
4480 the supported algorithm only if PKCS are registered. Affected
4481 file lib/silccrypt/silcpkcs.c. The same was done with the
4482 silc_pkcs_private_key_decode.
4484 * Fixed the SILC List routines to keep the list always in order.
4485 It used to change the list's order when traversing the list but
4486 not it preserves the order. Affected file lib/trq/silclist.h.
4488 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Added the client library to use the SilcSocketConnection's
4491 reference counter (by silc_socket_dup) to prevent the bug that
4492 the socket object may be freed underneath async operation.
4494 * The name resolv library checking fixes in the configure.in.pre.
4497 * Created new version of the protocol drafts for future
4498 development. The -03 drafts are the ones that will be changed
4499 in the trunk now and the -02 will remain as they are.
4501 * Send list of CUMODE notifys to the router when announcing
4502 the channel users to the router. Affected file silcd/server.c.
4503 If the router receiving channel founder CUMODE for a channel
4504 that already has channel founder it will send CUMODE notify
4505 to the sender to remove the channel founder rights from the
4506 announced client. Affected file silcd/packet_receive.c.
4508 * The CUMODE notify may now use Server ID as well as the entity
4509 who changes the mode. Updated protocool specs.
4511 * Updated INSTALL and README files.
4513 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * New web pages in the http://silc.pspt.fi. The pages was
4520 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Implemented the [DenyConnectin] config section in the server.
4523 Added silc_server_config_denied_conn to check whether incoming
4524 connection is denied. Affected file silcd/serverconfig.[ch].
4526 * Do not check the ports when checking the incoming configuration
4527 data if the port is 0, meaning any. Affected file is
4528 silcd/serverconfig.c.
4530 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Fixed buffer overflow in silc_string_compare in the file
4533 lib/silcutil/silcutil.c.
4535 * Fixed double free in silc_server_command_leave in the file
4538 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Fixed the version checking in the server. Affected file is
4543 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Fixed the configuration data fetching when accepting new
4546 connections in the server. Affected file silcd/server.c.
4548 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Added `sender_entry' argument to the function
4551 silc_server_packet_relay_to_channel so that we can check
4552 whether some destination actually belongs to the same route
4553 the sender belongs (ie, we must not resend the packet to the
4554 sender). Affected file silcd/packet_send.[ch].
4556 * Added `servername' field to the SilcClientEntry in the server
4557 to hold the name of the server where client is from. Affected
4558 file is silcd/idlist.h.
4560 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Moved the channel message encrypting in the router betwen
4563 router connections from silc_server_channel_message to the
4564 silc_server_packet_relay_to_channel since we want to check
4565 whether we have anybody channel before encrypting anything.
4566 Affected files silcd/packet_[receive/send].c.
4568 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Fixed the [AdminConnection] server config section to support
4571 multiple entries. Affected file silcd/serverconfig.c.
4573 * Added support into the server to check the validity of the
4574 incoming connection before executing any KE or authentication
4577 * The connection configuration is now saved to the KE and
4578 connection auth protocol contexts and not fetched anymore in
4579 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4581 * The local hosts listenning address and port is also resolved
4582 now when starting the server. We want to have the socket object
4583 to include the real address and port for the listener. Added
4584 new function silc_net_check_local_by_sock into the files
4585 lib/silcutil/silcnet.[ch].
4587 * Fixed a broadcast bug in server -> do not broadcast if we
4590 * Fixed a routing bug. Do not route broadcast packets ever.
4591 Broadcast packets must be processed always and not routed since
4592 they may be destined to some other host than yourself and thus
4593 would get routed without no good reason. Affected file is
4596 * Added function silc_server_config_is_primary_route to check
4597 whether primary router connection has been configured (a router
4598 configuration that we are initiating). If there is not, we
4599 will assume that there is only two routers in the SILC network
4600 and we will use the incoming router connection as our primary
4601 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4603 * Changed the order of the broadcasting. Broadcast _after_ the
4604 packet has been processed not before. Affected file is
4607 * Fixed a [ClientConnection] parsing bug. The port was never
4608 parsed correctly thus resulting to port 0. Affected file
4609 silcd/serverconfig.c.
4611 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4612 argument and did not set the broadcast packet flag. Affected
4613 file silcd/packet_send.c. Fixed same bug in the function
4614 silc_server_send_notify as well.
4616 * If we receive NEW_ID packet for our own ID in the server, ignore
4619 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Removed the nickname from the Private Message Payload.
4624 Updated the code and the protocol specs.
4626 * Updated protocol specs for submitting to the IETF.
4628 * Tweaked the Random Number Generator a bit. Affected file
4629 lib/silccrypt/silcrng.c. Exported a new function
4630 silc_rng_[global]_add_noise which can be used to add more
4633 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Do not parse packets with different timeout when protocol
4636 is active -> may cause problem with rekey. Affected file
4639 * When server receives signoff notify it must not create
4640 new channel key if the client is on any channels since the
4641 sender of the signoff notify will create it.
4643 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Added printing of error messages during SKE protocol from the
4646 failure packet sent by server during SKE. Affected file
4649 * Removed the client's failure_callback handling with timeout
4650 and handle it immediately when received.
4652 * The SKE library returned wrong type in SUCCESS and FAILURE
4653 packets. They must be 32 bit MSB not 16 bit MSB.
4655 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Ok, rewrote the logic of the re-key and now it seems to work.
4658 I tested it on high traffic with frequent re-keys without
4659 problems. Added hmac_receive (and renamed hmac to hmac_send)
4660 in SilcClientConnection in lib/silcclient/client.h and
4661 in SilcIDListData in silcd/idlist.h. Also, removed the
4662 SilcPacketParserContext's cipher and hmac fields as they are
4663 not needed anymore and actually caused some problems when
4664 the ciphers and hmac's changed underneath the packet parser.
4666 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * If re-key protocol is active then process the incoming packets
4669 synchronously since we must assure that icoming packets encrypted
4670 with the old key is processed before the new keys is set to
4671 use. This is true other packets than for REKEY packets.
4672 Affected file silcd/server.c. The same was done to client library
4673 as well, affected file lib/silcclient/client.c.
4675 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Fixed bug in client and server to accept the force send if
4678 the packet is send from silc_[server/client]_packet_process
4679 function. Otherwise the packets are never delivered, oops.
4681 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Disable force sending of packets when REKEY protocol is active.
4684 We must assure that no packet is sent directly when rekey is
4685 performed. All packets must be sent through packet queue.
4686 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4687 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4688 function is silc_[server/client]_packet_send_real to check
4691 * Replaced the SIM paths from example config files to
4692 /usr/local/modules. Also, make install creates now
4693 /usr/local/silc/logs directory to hold all the SILC server
4696 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Made the configure.in.pre work on Solaris. Patch by salo.
4700 * Made all ciphers compatible with non-x86 machines. Defined
4701 CBC mode macros into lib/silccrypt/ciphers_def.h.
4703 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Fixed the make install.
4707 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * When MAC computation fails the silc_packet_decrypt returned 0
4710 even though it was supposed to return -1. Fixed this. The
4711 affected file is lib/silccore/silcpacket.c.
4713 * Do not replace the config files in /etc/silc (in make install)
4714 if they already exist. Affected file ./Makefile.am.
4716 * Do not send re-key packets immediately but through packet queue.
4717 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4719 * Changed silc_net_check_host_by_sock to return FALSE if the
4720 IP/DNS could not be resolved. Though, it returns the IP address
4721 now even if it could not resolve it (but returns also FALSE).
4722 Affected file lib/silcutil/silcnet.[ch].
4724 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Added silc_pkcs_decode_identifier to decode the public key's
4727 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4728 Added also silc_pkcs_free_identifier. Added also new context
4729 SilcPublicKeyIdentifier.
4731 * Added -S option to the silc client. It is used to dump the
4732 contents of the specified public key file.
4734 * Changed the PKCS api to return the public key length when
4735 setting the public key.
4737 * Fixed a fatal bug in the public and private key file loading.
4738 Affected file lib/silccrypt/silcpkcs.c.
4740 * Execute the packet parsing for client with zero (0) timeout
4741 if the protocol is active. Affected file silcd/server.c.
4743 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Made the key generation options to the silcd program. Added
4746 -C option, equivalent to client's option.
4748 * Added new [ServerKeys] config section to the server. It
4749 configures the server's public and private key.
4751 * Defined generic Public Key Payload into the protocol
4752 specification to send specific type of public keys and
4755 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4756 public key or certificate.
4758 * Implemented the GETKEY command to the server and to the
4759 client library and on user interface.
4761 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Made preliminary `make install' work.
4765 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Added SilcServerRekey context into silcd/idlist.h.
4769 * Added the PFS support as defined in the specification to the
4770 SKE protocol. Affected files lib/silcske/*.c.
4772 * Added `ske_group' field to the SilcServerRekey context to hold
4773 the number of the SKE group that is used with PFS in re-key.
4774 Affected file silcd/idlist.h.
4776 * Added PFS re-key support to the server. Affected file is
4779 * Added silc_protocol_cancel to cancel execution of the next
4780 state of the protocol. Affected file is
4781 lib/silccore/silcprotocol.[ch].
4783 * Added the re-key support with and without PFS to the client
4784 library. Re-key is performed once in an hour, by default.
4786 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4787 Added silc_client_rekey_callback and silc_client_rekey_final.
4788 Affected files are lib/silcclient/protocol.[ch] and
4789 lib/silcclient/client.[ch].
4791 * Removed the `hmac_key' and `hmac_key_len' fields from the
4792 SilcClientConnection structure; not needed. Affected file is
4793 lib/silcclient/client.h.
4797 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Do not ask whether user wants to use the negotiated private key
4800 for private messages, just use it. Affected file is
4801 silc/local_command.c.
4803 * Added `send_enc_key' and `enc_key_len' fields to the
4804 SilcIDListData structure since they are needed in the re-key
4805 phase. Affected file is silcd/idlist.[ch].
4807 * Implemented the simple re-key protocol into the server.
4808 Affected files silcd/server.c and silcd/protocol.[ch]. The
4809 re-key will be performed once in an hour, by default.
4811 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4812 Added silc_server_rekey, silc_server_rekey_callback and
4813 silc_server_rekey_final.
4815 * Removed Tunneled flag from the protocol. Updated the code
4816 and the specifications.
4818 * Adde `pfs' field to the SilcIDListData to indicate whether
4819 the PFS is to be performed in the re-key. Affected file is
4822 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4825 int64 of at least the xintXX size. If void * is less that 4
4826 bytes uint32 * will be used. Defined bool as boolean.
4828 * Changed _ALL_ unsigned long and unsigned int to uint32,
4829 unsgined short to uint16 in the source tree.
4831 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4832 not handle clients that has entry->data.registered == FALSE.
4833 They are not in the network anymore. Affected file is
4836 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Implemented the sending of the SERVER_SIGNOFF notify in the
4839 server. Affected file is silcd/server.c.
4841 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4842 Added also silc_notify_payload_encode_args into the
4843 lib/silccore/silcnotify.[ch].
4845 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4846 Affected file silcd/packet_receive.c.
4848 * Implemented the SERVER_SIGNOFF notify handling in the client
4849 library. Affected file lib/silcclient/client_notify.c. Also,
4850 implemnted the printing of the SERVER_SIGNOFF info to the
4851 application. Affected file silc/client_ops.c.
4853 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4854 if the deleting was successful. Affected file silcd/idlist.[ch].
4856 * Added support for public key authentication in the connection
4857 authentication protocol in the client library. Affected file
4858 lib/silcclient/protocol.c.
4860 * Changed the server's silc_idlist_get_clients_by_* interface
4861 to support already allocated array so that new entries may be
4862 added to pre-allocated array. Affected file silcd/idlist.[ch].
4863 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4864 and command replies.
4866 * All command reply functions in the server now calls the
4867 pending command callback even if error occured. This way the
4868 error will be delivered to the client as well. Affected files
4869 silcd/command.c and silcd/command_reply.c.
4871 * Fixed INFO command to return local server's info if no server
4872 was provided. Affected file lib/silcclient/command.c.
4874 * Removed RESTART command for good. Updated the code and the
4877 * Rewrote parts of the task system. It is a bit simpler now.
4878 Removed unsued task priorities. The affected files are
4879 lib/silcutil/silctask.[ch].
4881 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Moved the USERS printing from the library to the application.
4884 Affected files lib/silcclient/command.c and silc/client_ops.c.
4886 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Added channel key re-key support. The re-key is perfomed
4891 only by the router and is done once in an hour. Added `rekey'
4892 field to the SilcChannelEntry in the server. Affected files
4893 silcd/server.c and silcd/idlist.h.
4895 * Added silc_task_unregister_by_context into the file
4896 lib/silcutil/silctask.[ch].
4898 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Added SILC_UMODE_GONE mode to indicate when the client is not
4901 present in the SILC network. Added also support to the local
4902 command AWAY that will set this mode. Added support of showing
4903 "xxx is gone" in WHOIS command. The USERS command shows the
4904 gone status as well.
4906 * Fixed setting server and router operator privileges in the
4907 server's UMODE command. Affected file silcd/command.c.
4909 * Merged the SKE KE1 and KE2 payloads into one payload. The
4910 new KE payload is equivalent to the old KE2 payload.
4912 Cleaned up the SKE Start Payload parsing. It now uses the
4913 simple buffer unformatting to do the parsing. A lot faster
4916 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4917 to the SKE that is used to indicate whether both of the SKE
4918 parties should perform authentication. By default only the
4919 responder performs authentication. By setting this flag also
4920 the initiator must do authentication. By default it is unset
4921 since in normal SKE case, client to server connection, only
4922 the responder should do authentication. When doing SKE between
4923 two clients both should perform authentication. Updated the
4924 code and the protocol specs.
4926 * A little fix to IDENTIFY command in the server. Search the
4927 client first by hash not nickname. Affected file is
4930 * Fixed the silc_client_close_connection to support closing
4931 the client to client connections wihtout deleting too much
4932 data. Affected file lib/silcclient/client.c.
4934 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4935 are received if protocol used to be active but is not anymore
4936 the application would crash due to NULL pointer dereference.
4937 Affected files silcd/server.c and lib/silcclient/client.c.
4939 * Added `hash' field to the SilcClientConnection to include
4940 the hash function negotiated in the SKE protocol.
4942 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4943 to set the channel founder authentication data. A client can
4944 claim the founder rights later by providing the authentication
4945 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4946 This way the channel founder can regain the channel founder
4947 privileges even it is left the channel. This works only on
4948 local server and the client must be connected to the same
4949 server to be able to regain the founder rights. Updated the
4950 protocol specs accordingly.
4952 Added support to the CMODE command in the client to set the
4953 founder auth data. Read the README to see how to set it.
4955 Added support to the CUMODE command to claim the founder
4956 rights. Read the README to see how to do it.
4958 Added support for the founder authentication to the Channel
4959 Entry in the server. Affected file silcd/idlist.h.
4961 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4962 server's CMODE command. Affected file silcd/command.c.
4964 * Added the following new functions into lib/silccore/silcauth.[ch]:
4965 silc_auth_get_method and silc_auth_get_data.
4967 * The server now saves the remote hosts public key to the
4968 SilcIDListData pointer. Affected file silcd/protocol.c.
4970 * The normal server now does not remove the channel entry from
4971 the cache if the founder authentication data is set. It used
4972 to remove it if the founder was the last one on the channel on
4973 the server and left the channel. The auth data is saved and
4974 if the channel is re-joined later the old entry is used with
4975 the old auth data. Affected files silcd/command_reply.c and
4978 * Removed the `pkcs' field from the SilcIDListData structure
4979 in the server; it is not used. Affected file silcd/idlist.h.
4981 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Fixed packet processing on slow links. Partial packets were
4984 never re-processed because the incoming data buffer was cleared
4985 by the application. Application must not directly clear the
4986 sock->inbuf, the packet processing routines handle it. Fixed
4987 this in client library and in server.
4989 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Fixed the WHOIS and IDENTIFY send reply function to really
4992 check whether to send list or just one entry. Affected file
4995 * Cleaned up the LEAVE command's channel key distribution. The
4996 affected file silcd/command.c.
4998 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4999 can enforce the channel mode as well. In that case the ID
5000 includes the ID of the server. The code now enforces the
5001 mode change if the router have different mode than the server.
5003 * The notify client operation with CMODE_CHANGE notify can now
5004 return NULL client_entry pointer if the CMODE was not changed
5005 by client. Application must check for this.
5007 * Added <Server ID> argument to INFO command to support server
5008 info fetching by Server ID.
5010 * Added silc_server_announce_get_channel_users to get assembled
5011 packets of channel users of the specified channel. Affected
5012 file silcd/server.[ch].
5014 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5015 was freed underneath the ID Cache.
5017 * Re-announce clients when the server received CHANNEL_CHANGE
5018 notify from the router. Affected file silcd/packet_send.c.
5020 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5023 crashed since it did not handle the fact that there is no cipher
5024 called "3" and didn't check the error condition. Now fixed.
5026 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5027 flag. It can be used to send message requests.
5029 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Implemented the RESTART command in the client.
5033 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5034 notice type messages. Added notice printing to the user
5037 * The channel keys are not re-generated if the channel's mode
5038 is PRIVKEY, ie private key on the channel exists. Affected
5039 files silcd/server.c and silcd/command.c.
5041 * Fixed a little bug in channel message delivery when channel
5042 private keys are set in the server. Affected file is
5043 silcd/packet_send.c.
5045 * Changed the setting on channel->on_channel = TRUE from the
5046 silc_client_save_channel_key to the JOIN command reply. The
5047 key payload is not received if the private channel key is set.
5048 Affected file lib/silcclient/command_reply.c and the
5049 lib/silcclient/client_channel.c.
5051 * When the CMODE_CHANGE notify is sent and the channel private
5052 key mode is removed the channel key must be re-generated in
5053 other cells as well. Added this support for the router in the
5054 silcd/packet_receive.c.
5056 * Added new local command NOTICE to send notice message on
5057 channel. Affected file silc/local_command.[ch].
5059 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Added new local command ME to the client. It is used to send
5062 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5063 some action. Affected file silc/local_command.[ch].
5065 * Changed channel_message and private_message client operations
5066 to deliver the message flags to the application. Added also
5067 the `flags' arguments to the silc_client_send_channel_message
5068 and silc_client_send_private_message functions. Affected file
5071 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Redefined the Private Message Payload to support private message
5074 keys and to support the new private message flags. Updated
5075 the protocol specs. Flags makes it possible to have for example
5076 CTCP style messages.
5078 * Added new type SilcPrivateMessagePayload and defined an API
5079 for it in the lib/silcclient/silcprivate.[ch].
5081 * Tested private message private keys successfully. Tested the
5082 private message key set, unset and list commands with the new
5085 * Redefined the Channel Message Payload to include the channel
5086 message flags (equal with private message flags) to support
5087 for example CTCP style messages.
5089 * Defined some of the message (for channel and private message)
5090 flags. Updated the protocol specs and added the flags to the
5091 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5093 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Added SilcKeyAgreementStatus type to the key agreement routines
5096 to indicate the current status and error if one occured.
5097 The status types are defined in the lib/silcclient/silcapi.h.
5099 * Added new local command KEY that is used to set and unset private
5100 keys for channels, set and unset private keys for private messages
5101 with remote clients and to send key agreement requests and
5102 negotiate the key agreement protocol with remote client. The
5103 key agreement is supported only to negotiate private message keys,
5104 it currently cannot be used to negotiate private keys for channels,
5105 as it is not convenient for that purpose.
5107 * Fixed a minor pending callback setting bug in the function
5108 silc_client_get_client_by_id_resolve, now the function works.
5109 Affected file lib/silcclient/idlist.c.
5111 * Added function silc_net_get_local_port to get local bound
5112 port by socket. Added to lib/silcutil/silcnet.[ch].
5114 * Added `sockets' and `sockets_count' fields to the SilcClient
5115 object. They hold the sockets of the listenning sockets in
5116 the client. Listenning sockets may be for example the key
5117 agreement server. Affected file lib/silcclient/client.[ch].
5118 Added functions the silc_client_add_socket and the
5119 silc_client_del_socket. They are exported to the application
5122 * Added ~./silc/clientkeys to support other client's public keys.
5124 * Renamed verify_server_key client operation to verify_public_key
5125 and added one argument to indicate the type of the connection
5126 (server, client etc.).
5128 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Added silc_server_connection_auth_request to handle the
5131 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5132 silcd/packet_receive.[ch].
5134 * Added silc_server_send_connection_auth_request into the
5135 silcd/packet_send.c to send the connection auth request packet.
5137 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5140 * Fixed the public key authentication in responder side in the
5141 server. The `auth_data' pointer includes the SilcPublicKey
5142 not the path to the public key. Affected file silcd/protocol.c.
5144 * Implemented the public key authentication in the initiator side
5145 in the server. Affected file silcd/protocol.c.
5147 * Removed the [RedirectClient] config section from the server
5148 configuration. Is not needed and I don't want to implement it.
5150 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Cleaned up the CMODE command in the server. It now works
5153 correctly and supports all the modes defined in the protocol.
5154 Affected file is silcd/command.c.
5156 * Added `hmac_name' field to the SilcChannelEntry in the server
5157 to hold the default HMAC of the channel. It can be set when
5158 creating the channel (with JOIN command). Affected files
5161 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5162 type to indicate the change of the current cipher and hmac
5163 on the channel. Client can safely ignore the <cipher> argument
5164 (if it chooses to do so) since the CHANNEL_KEY packet will
5165 force the channel key change anyway. The <hmac> argument is
5166 important since the client is responsible of setting the new
5167 HMAC and the hmac key into use.
5169 * Fixed the CMODE command in the client library as well.
5171 * Tested CMODE command in router environment successfully.
5173 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Show the version of the remote client (or server) when connecting
5176 to the server. It is logged to the log file. Affected file
5177 is silcd/protocol.c.
5179 * Fixed the KILLED notify handling in the client library. The
5180 client must be removed from all channels when receiving the
5183 Also, do not remove the client entry when giving the KILL
5184 command but when the KILLED notify is received.
5186 * Removed silc_idlist_find_client_by_nickname from the server.
5187 Not needed anymore. Affected files silcd/idlist.[ch].
5189 * Implemented the CHANNEL_CHANGE notify type handling to the
5190 server. Affected file silcd/server.c.
5194 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Added silc_server_send_notify_invite to send the INVITE
5197 notify between routers.
5199 * Implemented the INVITE command correctly to the server.
5201 * Implemented the INVITE notify type handling in the server.
5203 * Implemented the INVITE command to the client library and on the
5206 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Added function silc_server_get_client_resolve to find the
5209 client entry by ID from all ID lists and then resolve it
5210 (using WHOIS) if it cannot be found. Affected file is
5213 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Implemented the BAN command to the client library.
5217 * The JOIN command in the server now checks the invite list
5220 * Changed the silc_command_reply_payload_encode_va and the
5221 silc_command_payload_encode_va to support that if argument is
5222 NULL it ignores and checks the next argument. Affected file
5223 lib/silccore/silccommand.c.
5225 * Added silc_server_send_notify_ban to send the BAN notify
5226 type between routers.
5228 * Chaned the silc_notify_payload_encode to support that if
5229 argument is NULL it ignores and checks the next argument.
5230 Affected file lib/silccore/silcnotify.c.
5232 * Tested ban lists in router environment successfully.
5234 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Implemented BAN command to the server, in silcd/command.[ch].
5238 * Removed the BAN and INVITE_LIST modes from the CMODE command
5241 * Added function silc_string_match to regex match two strings.
5242 Affected files lib/silcutil/silcutil.[ch].
5244 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Redefined parts of the SilcChannelEntry in the server to support
5247 the new ban and invite lists.
5249 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Redefined the INVITE command. The same command can be used to
5252 invite individuals to the channel but also to manage the invite
5253 list of the channel (to add to and remove from the invite list).
5254 Updated the protocol specs.
5256 * Added new command SILC_COMMAND_BAN that can be used to manage
5257 the ban list of the channel. Updated the protocol specs.
5259 * Removed the channel modes: the SILC_CMODE_BAN and the
5260 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5261 in the CMODE command. The equivalent features are now available
5262 using INVITE and BAN commands. Updated the protocol specs.
5264 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5265 in the network about change in the current ban list. The notify
5266 type is not used by the client.
5268 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5269 support the invite lists.
5271 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Added new function silc_string_regexify that converts string
5274 including wildcard characters into regex string that can
5275 be used by the GNU regex library. Added into the file
5276 lib/silcutil/silcutil.[ch].
5278 Added silc_string_regex_combine to combine to regex strings
5279 into one so that they can be used as one regex string by
5280 the GNU regex library. Added into the file
5281 lib/silcutil/silcutil.[ch].
5283 Added silc_string_regex_match to match two strings. It returns
5284 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5286 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Imported GNU regex to the soruce tree into lib/contrib.
5289 Fixed some compiler warning from the regex.c.
5291 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Fixed MOTD command in the server to work in router environment.
5295 * Fixed the MOTD command in the client library to support
5296 the server argument in the command.
5298 * Added `nickname_len' argument to the silc_idlist_add_client
5299 in the server, as the `nickname' argument may be binary data
5302 * Added silc_idlist_get_channels to return all channels from
5305 * Implemented LIST command to the server. Affected file is
5308 * Implemented the LIST command to the client library and on the
5311 * Added [<user count>] argument to the LIST command reply.
5312 With private channels the user count is not shown.
5314 * Updated TODO and README.
5316 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * The client entry's data.registered must be TRUE even with
5319 global client entry on global client list. The data.registered
5320 is used to check whether the client is anymore in the network,
5321 for example with WHOWAS command so it must be valid.
5323 * Fixed the WHOWAS command in the server. It now actually works
5324 in router environment. Added function into silcd/command_reply.c
5325 silc_server_command_reply_whowas_save.
5327 * Added silc_idlist_purge function to the silcd/idlist.c
5328 to periodically purge the ID Cache.
5330 * Fixed INFO command in the server. It works now in router
5331 environment. Added <server name> argument to the INFO command
5332 reply. Updated the protocol specs.
5334 * Fixed minor bug in silc_idcache_purge to not purge if the
5335 expire value is zero.
5337 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5338 they were buggy because of the WHOWAS information.
5340 * Fixed local command MSG to handle the async resolving of
5341 the remote client properly. It used to fail the first MSG.
5342 Affected file silc/local_command.c.
5344 * Added `data_len' field to SilcIDCache context.
5346 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Update TODO. Todo in commands in the server.
5350 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5353 used by routers as broadcast packet to inform other routers
5354 about the changed user mode.
5356 Implemented the notify handling in the server. Affected file is
5357 silcd/packet_receive.c. Added the function
5358 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5360 * Added new generic Channel Payload and deprecated the New Channel
5361 Payload. The New Channel Payload is now the generic Channel
5364 * Added new argument `mode' to the silc_server_send_new_channel
5365 as it is required in the Channel Payload now.
5367 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5368 and created a new and real SilChannelPayload to represent the
5369 new generic Channel Payload. Implemented the encode/decode
5370 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5372 * Added silc_server_get_client_channel_list to return the list
5373 of channels the client has joined for WHOIS command reply.
5374 Affected file silcd/server.[ch].
5376 * Implemented the channel list sending in the WHOIS command reply
5377 in server and in the client.
5379 Implemented the channel list displaying on the user interface
5380 as well. Affected file silc/client_ops.c.
5382 * Added silc_channel_payload_parse_list to parse list of Channel
5383 Payloads. It returns SilcDList list of SilcChannelPayloads.
5384 Client for example can use this function to parse the list of
5385 channels it receives in the WHOIS command reply. The caller
5386 must free the list by calling silc_channel_payload_list_free.
5387 Affected files lib/silccore/silcchannel.[ch].
5389 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Added one new argument <user mode> to the WHOIS command reply
5392 to return the mode of the user in SILC. Updated the protocol
5395 Implemented it to the server and client.
5397 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Fixed the mode printing on the user interface on joining.
5400 Affected file silc/client_ops.c.
5402 * Implemented the UMODE command and user modes in general to the
5403 client library and to the user interface.
5405 * Implemented the UMODE command to the server.
5407 * The server now sends UNKNOWN_COMMAND error status if client sends
5408 unknown command. Affected file silcd/command.c.
5410 * All server commands now handle the command identifier the right
5411 way when sending the command reply to the client. The client can
5412 use to identify the command replies with the identifier.
5414 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Added silc_server_get_client_route to resolve the route to
5417 the client indicated by the client ID. Affected file is
5420 * Added silc_server_relay_packet as general function to relay
5421 packet to arbitrary destination. This deprecates functions
5422 like _send_private_message_key, _relay_notify etc. Affected
5423 file is silcd/packet_send.[ch].
5425 Removed silc_server_send_key_agreement,
5426 silc_server_send_private_message_key and
5427 silc_server_packet_relay_notify functions from the file
5428 silcd/packet_send.[ch].
5432 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5433 server. Affected file silcd/packet_receive.[ch].
5435 * Implemented the KILL command to the client. Implemented the
5436 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5437 Affected files lib/silcclient/command[_reply].c and
5438 lib/silcclient/client_notify.c. Implemented the KILL notify
5439 printing in the user inteface.
5441 * Fixed a lot silc_parse_nick memory leaks from the client
5442 library in the file lib/silcclient/command.c.
5444 * Changed the silc_server_send_notify_on_channels's `sender'
5445 argument from SilcSocketConnection to SilcClientEntry to
5446 check the sender as entry and not as connection object and not
5447 to send to the client provided as argument. The affected file
5448 is silcd/packet_send.[ch].
5450 * The notify packets that are destined directly to the client used
5451 to not to be processed by the server. Now changed that and the
5452 server processes all notify packets. After relaying the packet
5453 to the client the notify packet is processed in the server.
5455 * The silc_server_free_client_data now checks whether there is
5456 pending outgoing traffic for the client and purges the data to
5457 the network before removing the client entry.
5459 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5462 an client is killed from the SILC Network. Updated the protocol
5465 Added new function silc_server_send_notify_killed to the
5466 silcd/packet_send.[ch].
5468 * Added function silc_server_packet_relay_notify to relay notify
5469 packets that are destined directly to a client. In this case
5470 the server does not process the notify packets but merely relays
5471 it to the client. Affected file silcd/packet_send.[ch].
5473 Added also silc_server_packet_process_relay_notify to check
5474 whereto relay the notify. Affected file is
5475 silcd/packet_receive.[ch].
5477 * Implemented the KILL command to the server.
5481 * Added the backup schema desgined last fall to the protocol
5482 specs for everyone to see. The specification is in the
5483 *-spec-xx.txt draft and the packet type definitions for the
5484 backup routers is in *-pp-xx.txt draft. Thusly, added also
5485 new packet type SILC_PACKET_CELL_ROUTERS.
5487 * A big security problem in the implementation discovered. The
5488 signoff of an client did not cause new channel key generation
5489 which it of course should've done. The channel keys must be
5490 always re-generated when client leaves (or signoffs) the channel.
5491 The silc_server_remove_from_channels funtion now handles
5492 the channel key re-generation.
5494 * Added `sender' argument to the silc_server_send_notify_on_channels
5495 to not to send the client provided as argument. Affected file
5496 silcd/packet_send.[ch].
5498 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Implemented OPER and SILCOPER commands into the server and
5503 * Added silc_auth_verify and silc_auth_verify_data to verify
5504 the authentication directly from the authentication payload.
5505 It supports verifying both passphrase and public key based
5506 authentication. Affected file lib/silccore/silcauth.[ch].
5508 * Added `hash' field to the SilcIDListData structure. It is the
5509 hash negotiated in the SKE protocol. Affected file is
5512 * Slight redesigning of the SilcAuthPayload handling routines.
5513 Do not send SilcPKCS but SilcPublicKey as argument.
5515 * Implemented the public key authentication support to the
5516 serverconfig. The public key is loaded from the provided path
5517 and saved as authentication data to void * pointer. Thus,
5518 changed the unsigned char *auth_data to void *auth_data;
5520 * Fixed SHUTDOWN command to send the reply before the server
5521 is shutdown. :) Affected file silcd/command.c.
5523 * Fixed fatal bug in CONNECT command. The hostname was invalid
5524 memory and server crashed. Affected file silcd/command.c.
5526 * Fixed fatal bug in CLOSE command. The server_entry became
5527 invalid but was referenced later in the command. Affected file
5530 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Fixed fatal bug in failure packet handling. Server ignored
5533 the failure and thus crashed when it came.
5537 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5540 that the command may be executed only once in (about) 2 seconds.
5541 The old SILC_CF_LAG flag is same but allows command bursts up
5542 to five before limiting.
5544 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5545 server code. Various commands now includes the CF_LAG_STRICT
5546 flag to disallow any kind of miss-use of the command.
5548 * Fixed the silc_buffer_unformat to not to allocate any data
5549 if the length of the data is zero. It used to allocate the
5550 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5552 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Changed the format of AdminConnection configuration section
5555 in the server. Added username of the admin to the format.
5556 Affected files silcd/serverconfig.[ch].
5558 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5559 to return admin configuration data by host, username and/or
5562 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Implemented WHOWAS command to the server. Added the functions:
5566 silc_server_command_whowas_parse,
5567 silc_server_command_whowas_send_reply,
5568 silc_server_command_whowas_from_client and
5569 silc_server_command_whowas_from_server
5571 * Added <Client ID> argument to the WHOWAS command reply. Updated
5572 the protocol specs accordingly.
5574 * Implemented WHOWAS command and command_reply to the client
5577 Implemented the WHOWAS printing on the user interface.
5579 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Added new argument to the WHOWAS command reply, the real name.
5582 It is an optional argument. Updated the protocol specs.
5584 * Added SilcIDCacheDestructor callback that is registered when
5585 the SilcIDCache is allocated. The callback is called when
5586 an cache entry in the ID Cache expires, or is purged from the
5587 cache. Added into lib/silccore/idcache.[ch].
5589 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5590 to destruct the client entries when the cache entry expires.
5591 Other ID Cache's in server and in the client library ignores
5594 * If the ID Cache entry's `expire' field is zero then the entry
5595 never expires. Added boolean `expire' argument to the
5596 silc_idcache_add function in the lib/silccore/idcache.[ch].
5597 If it is TRUE the default expiry value is used.
5599 * Added silc_server_free_client_data_timeout that is registered
5600 when client disconnects. By default for 5 minutes we preserve
5601 the client entry for history - for WHOWAS command.
5603 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Added support to the server to enforce that commands are not
5606 executed more than once in 2 seconds. If server receives
5607 commands from client more frequently, timeout is registered
5608 to process the commands. Affected file silcd/command.c.
5609 Added new function silc_server_command_process_timeout.
5611 * Changed NICK_NOTIFY handling in client library to check that
5612 if the client's nickname was changed, so there is no need to
5613 resolve anything from the server.
5615 * Removed error printing from the WHOIS and IDENTIFY commands.
5616 If error occurs then it is ignored silently in the client library.
5617 The application, however, may map the received error to
5618 human readable error string. The application currently maps
5619 the NO_SUCH_NICKNAME error to string.
5621 * Made the command status message public to the application. Moved
5622 them from lib/silcclient/command_reply.c to
5623 lib/silcclient/command_reply.h. The application can map the
5624 received command status to the string with the
5625 silc_client_command_status_message function.
5627 * Added check to the server to check that client's ID is same
5628 as the Source ID in the packet the client sent. They must
5631 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Added dist-bzip hook to the Makefile.am to make bzip2
5634 compressed distributions.
5636 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Server now enforces the maximum length for the nickname and
5639 the channel as protocol specification dictates. 128 bytes for
5640 nickname and 256 bytes for channel name.
5642 * Moved the WHOIS printing to the application. The client libary
5643 does not print out the WHOIS information anymore, the application
5644 must do it. Renamed silc_client_command_reply_whois_print to
5645 the silc_client_command_reply_whois_save.
5647 The client's idle time is also sent to the application now, and
5648 the idle is shown on screen.
5650 * Added silc_client_command_reply_identify_save to save the
5651 received IDENTIFY entries.
5653 * Do not check for channel private keys in message sending and
5654 reception if the channel does not have the PRIVKEY mode set.
5655 Affected file lib/silclient/client_channel.c.
5657 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5660 just surfaced after chaning the JOIN procedure.
5662 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added silc_client_get_clients_by_list to get client entries
5665 from Client ID list, that is returned for example by JOIN
5666 and USERS command replies. The application should use this
5667 function for example when JOIN command reply is received to
5668 resolve the clients already on the channel (library does not
5669 do that anymore as USERS command reply is not used in the JOIN
5670 procedure anymore). Affected files lib/silcclient/silcapi.h and
5671 lib/silcclient/idlist.c.
5673 * JOIN command reply and USERS command reply returns now SilcBuffer
5674 pointers instead of unsigned char pointers when returning
5675 the client list and mode list.
5677 * Added <Client ID> argument to the JOIN command reply, mainly
5678 for the server to identify for which client the command was
5679 originally sent. Updated protocol specs accordingly.
5681 * Added SilcDlist private_key pointer to the SilcChannelEntry
5682 in the client to support the channel private keys. Affected
5683 file is lib/silcclient/idlist.h.
5685 * Added SilcChannelPrivateKey argument to the function
5686 silc_client_send_channel_message so that application can choose
5687 to use specific private ke if it wants to. If it is not provided,
5688 the normal channel key is used, unless private keys are set.
5689 In this case the first (key that was added first) is used
5690 as the encryption key.
5692 * Implemented the support for channel private key handling.
5693 Implemented the following functions:
5695 silc_client_add_channel_private_key,
5696 silc_client_del_channel_private_keys,
5697 silc_client_del_channel_private_key,
5698 silc_client_list_channel_private_keys and
5699 silc_client_free_channel_private_keys
5701 Affected file lib/silcclient/client_channel.c.
5703 * Added the support for the private keys in the channel message
5704 sending and encryption and in the message reception and
5705 decryption. Affected funtions are
5706 silc_client_send_channel_message and silc_client_channel_message.
5708 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Added SKE's key verify callback to the client library's
5711 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5713 * Removed the statement that server (or router) must send USERS
5714 command reply when joining to the channel so that the client
5715 knows who are on the channel. Instead, the client list and
5716 client's mode list is now sent in the JOIN command reply to the
5717 client who joined channel. This is better solution.
5719 * Added function silc_server_get_users_on_channel and function
5720 silc_server_save_users_on_channel to the silcd/server.[ch].
5722 * Removed function silc_server_command_send_users from the
5725 * Do not show topic on the client library anymore. The topic is
5726 sent in the command reply notify to the application and the
5727 application must show the topic now.
5729 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Added client searching by nickname hash into the IDENTIFY and
5732 WHOIS commands in the server as they were clearly missing from
5733 them. Affected file is silcd/command.c.
5735 * Fixed a bug in private message receiving in the client library.
5736 The remote ID was freed and it wasn't supposed, now it is
5739 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Minor fix to the channel payload; allocate the data area, as it
5742 needs to be of specific length.
5744 * If the key agreement port is zero then the operating
5745 system will define the bound port. Affected files are
5746 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5748 * Added new function silc_channel_payload_decrypt into the file
5749 lib/silccore/silcchannel.[ch].
5751 * Moved the channel message etc, check from silc_packet_decrypt
5752 to applications. The library calls now a generic
5753 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5754 when the packet is either normal or special. This was done to
5755 allow more wide range of checking that was not allowed when
5756 the code was in library. Now applications can do virtually any
5757 checks to the packet and return to the library the decision how
5758 the packet should be processed. Affected files are
5759 lib/silccore/silcpacket.[ch].
5761 Added silc_server_packet_decrypt_check to the server and
5762 silc_client_packet_decrypt_check to the client library.
5764 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5765 to send with specified source and destination information.
5767 * Channel message delivery between routers was broken after the
5768 channel key distribution was fixed earlier. The channel key
5769 was used be to distributed to other routers as well which is not
5770 allowed by the protocol. Now this is fixed and channel keys
5771 really are cell specific and the channel message delivery between
5772 routers comply with the protocol specification.
5774 * Fixed various commands in server to check also the global list
5775 for the channel entry and not just the local list. The affected
5776 file silcd/command.c.
5778 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Added assert()s to buffer formatting and unformatting routines
5781 to assert (if --enable-debug) when error occurs. Affected
5782 file: lib/silcutil/silcbuffmt.c.
5784 * Changed to auto-reconnect to check whether the remote host is
5785 router and register the re-connect timeout if it is. It used
5786 to check that whether we are normal server, but router must do
5787 auto-reconnect with another router as well. Affected file
5790 * Removed the [<key len>] option from CMODE command as the cipher
5791 name decides the key length, nowadays. See the defined ciphers
5792 from the protocol specification.
5794 * Added [<hmac>] option to the CMODE command to define the HMAC
5795 for the channel. Added SILC_CMODE_HMAC channel mode.
5797 * Added [<hmac>] option for the JOIN command so that user can
5798 select which HMAC is used to compute the MACs of the channel
5801 * Added Hmac field to the Channel Message Payload. The integrity
5802 of plaintext channel messages are now protected by computing
5803 MAC of the message and attaching the MAC to the payload. The
5804 MAC is encrypted. Now, it is clear that this causes some
5805 overhead to the size of the packet but rationale for this is that
5806 now the receiver can verify whether the channel message decrypted
5807 correctly and also when private keys are set for the channel the
5808 receiver can decrypt the packet with several keys and check from
5809 the MAC which key decrypted the message correctly.
5811 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5812 lib/silccrypt/silccipher.[ch].
5814 * Added silc_hash_len to return the digest length into the
5815 lib/silcrypt/silchash.[ch].
5817 * Rewrote parts of Silc Channel Payload interface in the
5818 lib/silccore/silcchannel.[ch]. The encode function now also
5819 encrypts the packet and parse function decrypts it.
5821 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5823 * Fixed a minor formatting bug in the SKE's key material processing.
5824 It actually might have processed the keys wrong way resulting
5827 * Redefined the mandatory HMAC algorithms and added new algorithms.
5828 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5829 and hmac-md5 truncated to 96 bits. The mandatory is now
5830 hmac-sha1-96. Rest are optional (including the one that used
5831 to be mandatory). Rationale for this is that the truncated HMAC
5832 length is sufficient from security point of view and can actually
5833 make the attack against the HMAC harder. Also, the truncated
5834 HMAC causes less overhead to the packets. See the RFC2104 for
5837 * Added new [hmac] configuration section. The SKE used to use
5838 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5839 is of course wrong. The official names that must be proposed in
5840 the SKE are the ones defined in the protocol specification
5841 (hmac-sha1-96 for example). The user can configure any hmac
5842 using any hash function configured in the [hash] section. At
5843 least, the mandatory must be configured.
5845 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5847 * Added HMAC list to the SKE proposal list. It has now both
5848 hash algorithm list and HMAC list. This makes the protocol
5849 incompatible with previous versions. The SKE now seems to work
5850 the way it is supposed to work, for the first time actually.
5852 * Defined plain Hash algorithms to the protocol specification.
5855 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Implemented support for key agreement packets into the server.
5858 Added functions silc_server_key_agreement and
5859 silc_server_send_key_agreement. Other than these functions,
5860 server has nothing to do with this packet.
5862 * Added support for private message key packets into the server.
5863 Added functions silc_server_private_message_key and
5864 silc_server_send_private_message_key.
5868 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5869 called in the protocol's final callback instead in the END
5870 protocol state. This makes a little more sense and in the same
5871 time in client we can use the same protocol routines for normal
5872 key exchange and to key agreement packet handling as well.
5874 * Added to both client's and server's KE protocol context the
5875 SilcSKEKeyMaterial pointer to save the key material. We will
5876 bring the key material to the protocol's final callback by doing
5877 this. The final callback must free the key material.
5879 * Added SKE's packet_send callback into client's KE protocol
5880 context so that the caller can choose what packet sending function
5881 is used. This way we can use different packet sending when
5882 doing normal SKE when doing key agreement packet handling (in
5883 the key agreement packet handling we do not want to encrypt
5886 * Implemented the responder side of the key agreement routines
5887 in the client. The client can now bind to specified port and
5888 accept incoming key negotiation. The key material is passed
5889 to the application after the protocol is over.
5891 * Implemented the processing of incoming Key Agreement packet
5892 in the client. Added function silc_client_key_agreement to
5895 * Implemented the intiator side of the key agreement routines
5896 in the client. The client can now initiate key agreement with
5897 another remote client. The key material is passed to the
5898 application after the protocol is over.
5900 * Created client_keyagr.c to include all the key agreement
5903 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5904 SILC_TASK_CALLBACK except that it is not static.
5906 * Created client_notify.c and moved the Notify packet handling
5907 from the client.[ch] into that file.
5909 * Created client_prvmsg.c and moved all private message and
5910 private message key routines from the client.[ch] into that file.
5912 * Create client_channel.c and moved all channel message and
5913 channel private key routines from the client.[ch] into that file.
5915 * Changed silc_client_get_client_by_id_resolve to resolve with
5916 WHOIS command instead of IDENTIFY command, in the file
5917 lib/silclient/idlist.c.
5919 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Implemented the SKE's responder side to the Client library.
5923 * When FAILURE is received to the protocol do not trust it
5924 blindly. Register a timeout to wait whether the remote closes
5925 the connection as it should do it, only after that process the
5926 actual failure. This was changed to both client and server.
5928 * Added client_internal.h to include some of the structures
5929 there instead of client.h in lib/silcclient/.
5931 * Added function silc_task_unregister_by_callback to unregister
5932 timeouts by the callback function.
5934 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Some "Incomplete WHOIS info" errors has been appearing on the
5937 log files. Took away the entry->userinfo check from WHOIS
5938 reply sending. The entry->userinfo is now " " if client did not
5939 provide one. I thought this was fixed earlier but something
5940 is wrong still. Let's see if the error still appears.
5942 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Fixed a minor bug in the login when the channel key is
5945 re-generated in the server. It used to generate the key in
5946 wrong order and thus caused problems in the channel traffic.
5948 * Fixed a minor bug in channel key distsribution after
5949 KICK command. The key was not sent to the router even though
5952 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added silc_ske_process_key_material_data as generic routine
5955 to process any key material as the SILC protocol dictates. The
5956 function is used by the actual SKE library but can be used by
5957 applications as well. This relates to the private message keys
5958 and the channel private keys since they must be processed the
5959 same way the normal SILC session keys. The protocol dictates
5960 this. Affected files: lib/silcske/silcske.[ch].
5962 Added also silc_ske_free_key_material to free the
5963 SilcSKEKeyMaterial structure.
5965 * Defined silc_cipher_set_key function to set the key for
5966 cipher without using the object's method function. The affected
5967 files: lib/silccrypt/silccipher.[ch].
5969 * Implemented silc silc_client_add_private_message_key,
5970 silc_client_add_private_message_key_ske,
5971 silc_client_del_private_message_key,
5972 silc_client_list_private_message_keys and
5973 silc_client_free_private_message_keys functions in the
5976 Added functions silc_client_send_private_message_key to send
5977 the Private Message Key payload and silc_client_private_message_key
5978 to handle incoming Private Message Key payload.
5980 * Added Cipher field to the Private Message Key payload to set
5981 the cipher to be used. If ignored, the default cipher defined
5982 in the SILC protocol (aes-256-cbc) is used.
5984 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Removed lib/silcclient/ops.h file.
5988 Redefined parts of the SILC Client Library API. Created new
5989 file silcapi.h that deprecates the ops.h file and defines the
5990 published Client Library API. Defined also private message key
5991 API and channel private key API into the file.
5993 This is the file that the application must include from the
5994 SILC Client Library. Other files need not be included by
5995 the application anymore.
5997 * Added new key_agreement client operation callback and also
5998 defined the Key Agreement library API for the application.
6000 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6003 is used by clients to request key negotiation between another
6004 client in the SILC network. If the negotiation is started it
6005 is performed using the SKE protocol. The result of the
6006 negotiation, the secret key material, can be used for example
6007 as private message key.
6009 Implemented the Key Agreement payload into the files
6010 lib/silccore/silauth.[ch].
6012 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Redefined ciphers for the SILC protocol. Added some new ciphers
6015 and defined the key lengths for the algorithms. Changed the
6016 code accordingly. The default key length is now 256 bits.
6018 * Fixed SKE key distribution function silc_ske_process_key_material
6019 when the key length is more than 128 bits. The default key
6020 length in SILC is now 256 bits.
6022 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6023 to indicate unsupported algorithm.
6025 * Renamed rijndael.c to aes.c and all functions as well.
6027 * Fixed a long standing channel key setting bug in client library.
6028 Weird that it has never surfaced before.
6030 * Fixed bug in channel deletion. If the entire channel is removed
6031 then it must also delete the references of the channel entry
6032 from the client's channel list as the client's channel entry and
6033 the channel's client entry share same memory.
6035 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Implemented CONNECT and SHUTDOWN commands in the client.
6039 * Implemented CLOSE command to the client.
6041 * Added the function silc_idlist_find_server_by_name into the
6042 files silcd/idlist.[ch].
6044 Added the function silc_idlist_find_server_by_conn into the
6045 files silcd/idlist.[ch].
6047 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6049 * DIE command was renamed to SHUTDOWN. Updated the both code
6052 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6053 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6055 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6058 * Added function silc_server_create_connection function to create
6059 connection to remote router. My server implementation actually
6060 does not allow router to connect to normal server (it expects
6061 that normal server always initiates the connection to the router)
6062 so the CONNECT command is only good for connecting to another
6065 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6068 or some other client was kicked from the channel.
6070 Implemented the handling of the notify type to both client
6073 Implemented silc_server_send_notify_kicked to send the KICKED
6074 notify. It is used to send it to the server's primary router.
6076 * Implemented the KICK command into server and client.
6078 * Added `query' argument to the silc_idlist_get_client function
6079 to indicate whether to query the client from server or not if
6082 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6083 to indicate that the client is not channel founder.
6087 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Removed the rng context from SilcPacketContext structure and
6090 changed that the packet routine uses the Global RNG API.
6092 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Added support for quit message that client can "leave" on the
6095 channel when it quits the SILC. It is ditributed inside the
6096 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6098 Added silc_server_free_client_data that will take the
6099 signoff message as argument.
6101 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6103 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Updated parts of the protocol specification to keep it up
6108 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6111 payloads in one packet.
6113 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6114 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6115 use now the new List flag.
6117 * Also deprecated the following packet types: REPLACE_ID,
6118 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6120 * Added list support for Notify packet in server.
6122 * Added silc_server_send_notify_channel_change to send the
6123 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6124 the silc_server_send_replace_id.
6126 * Added silc_server_send_notify_nick_change to send the
6127 NICK_CHANGE notify type. Deprecates the function
6128 silc_server_send_replace_id.
6130 * Added silc_server_send_notify_join to send the JOIN notify type.
6131 Deprecates the function silc_server_send_new_channel_user.
6133 * Added silc_server_send_notify_leave to send LEAVE notify type.
6134 Deprecates the function silc_server_send_remove_channel_user.
6136 * Added silc_server_send_notify_cmode and
6137 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6138 types. Deprecates the silc_server_send_set_mode function.
6140 * Added SERVER_SIGNOFF notify type to indicate that server has
6141 quit. This means that all clients on the channel from that
6142 server will drop. This can be also used when netsplit happens.
6144 Deprecated REMOVE_ID packet type since it is not needed anymore
6147 Added silc_server_send_notify_server_signoff to send the
6148 SERVER_SIGNOFF notify type. Deprecates the function
6149 silc_server_send_remove_id.
6151 Added also silc_server_send_notify_signoff to send the
6152 SIGNOFF notify type.
6154 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6155 SILC protocol from this day on. Changed the protocol
6156 specification as well.
6158 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6159 notify type. It is used between routers to notify about
6160 topic changes on a channel.
6162 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6165 * Partly updated the protocol specification to comply with the
6166 changes now made. It is still though a bit outdated.
6168 * The JOIN notify type now takes one extra argument <Channel ID>.
6169 The packet used to be destined to the channel but now the
6170 JOIN type may be sent as list thus it is impossible to
6171 destine it to any specific channel. By adding this argument
6172 it is again possible.
6174 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Added CREDITS file. The CHANGES and CREDITS file will appear
6177 in the distribution as well.
6179 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6182 types in the server's silcd/packet_receive.c.
6184 * Implemented CMODE and CUMODE to work in router environment.
6186 * Fixed minor encoding and decoding buglet from the
6187 lib/silccore/silcmode.c.
6189 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6192 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6194 * Changed all SilcConfigServer* and silc_config_server* to
6195 SilcServerConfig* and silc_server_config*, respectively.
6198 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Associated the ID (client or server ID) to the Authentication
6201 Payload to avoid any possibility of forging. Updated the
6202 protocol specification and the code accordingly.
6204 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * The RSA key length is now save to the RsaKey context in the
6207 key generation process in lib/silccrypt/rsa.c. The key length
6208 is now used to figure out the maximum size of the block allowed
6209 to be encrypted/signed.
6211 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6212 is equivalent to the silc_mp_mp2bin but does not allocate any
6215 * Changed silc_mp_mp2bin API to take length argument. If it is
6216 non-zero then the buffer is allocated that large. If zero, then
6217 the size is approximated using silc_mp_sizeinbase, which however
6220 * Created Global RNG API which is global RNG that application can
6221 initialize. After initializing, any routine anywhere in the
6222 code (including library) can use RNG without allocating a new
6223 RNG object. This was done to allow this sort of use of the
6224 RNG in code that has no chance to allocate RNG object. All
6225 applications currently allocate this and many routines in the
6226 library use this. Affected file lib/silccrypt/silcrng.[ch].
6228 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6229 it to use the Global RNG API.
6231 * Defined Authentication Payload into protocol specification that
6232 is used during SILC session to authenticate entities. It is
6233 used for example by client to authenticate itself to the server
6234 to obtain server operator privileges.
6236 Implemented this payload into the lib/silccore/silcauth.[ch].
6237 Implemented also routines for public key based authentication
6238 as the new protocol specification dictates.
6240 Moved definitions of different authentication methods from
6241 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6243 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6244 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6245 silc_pkcs_verify_with_hash functions into the file
6246 lib/silccrypt/silcpkcs.[ch].
6248 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * The client entry's userinfo pointer must be always valid.
6251 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6252 will fail since it requires the userinfo. Now, the userinfo
6253 is allocated as "" if actual userinfo does not exist. Actually,
6254 it must exist and it is totally Ok to drop client connections
6255 that does not announce the userinfo. However, we will make
6256 this workaround for now.
6258 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6259 to return the remote port by socket.
6261 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6264 SILC_SERVER_PENDING_EXEC and added an new macro
6265 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6266 data or when error occurs while processing the pending command.
6268 Added new argument `destructor' into silc_server_command_pending
6269 and to the SilcServerCommandPending object. This destructor is
6270 now called after calling the pending callback or if error occurs
6271 immediately. If error occurs the actual pending callback won't
6272 be called at all - only the destructor. The destructor may be
6273 NULL if destructor is not needed.
6275 All this applies for client library code as well. Similar
6276 changes were made there as well for the pending commands.
6278 In the client, the application must now allocate the
6279 SilcClientCommandContext with the silc_client_command_alloc
6282 * Added reference counter to the SilcServerCommandContext. Added
6283 function silc_server_command_alloc and silc_server_command_dup
6286 Same type of functions added to the client library for the same
6289 * Removed the cmd_ident from IDListData away since it is now
6290 global for all connections. It is the command identifier used
6291 in command sending and with pending commands. The affected file
6294 * Added reference counter to the SilcSocketConnection objecet to
6295 indicate the usage count of the object. The object won't be
6296 freed untill the reference counter hits zero. Currently only
6297 server uses this, and client ignores it. The client must be
6298 set to use this too later. The affected files are
6299 lib/silccore/silcsockconn.[ch]. Added also the function
6300 silc_socket_dup to increase the reference counter.
6302 This was mainly added because it is possible that the socket
6303 is removed underneath of pending command or other async
6304 operation. Now it won't be free'd and proper DISCONNECTING
6305 flags, etc. can be set to avoid sending data to connection that
6306 is not valid anymore.
6308 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6309 the connection. After that it sets SILC_SET_DISCONNECTED.
6310 It is, however, possible that the socket data is not still freed.
6311 The silc_server_packet_process now checks that data is not
6312 read or written to connection that is DISCONNECTED. The socket
6313 get's freed when the reference counter hits zero.
6315 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Changed the client operation API: channel_message operation's
6318 `sender' is now the client entry of the sender, not the nickname
6319 and the `channel' is the channel entry, not the channel name.
6321 In the private_message operation the `sender' is now also the
6322 client entry of the sender not the nickname.
6324 Affected file is lib/silcclient/ops.h and all applications
6325 using the client operations.
6327 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Moved the calling of ops->connect() from connect_to_server_final
6330 into receive_new_id functin since that is the point when the
6331 client is actually allowed to send traffic to network. The
6332 affected file is lib/silcclient/client.c.
6334 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6337 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6338 (if needs broadcasting) instead of broadcasting the packets one
6339 by one which would make a burst in the network traffic.
6341 * Added `broadcast' argument to the functions in silcd/server.[ch]
6342 silc_server_create_new_channel[_with_id] to indicate whether
6343 to send New Channel packet to primary router.
6345 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Added new function into the silcd/server.[ch] files:
6348 silc_server_create_new_channel_with_id to create new channel with
6349 already existing Channel ID.
6351 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6352 lib/silccore/silcpacket.h. This packet is used t send list of
6353 Set Mode payloads inside one packet. Server uses this to set
6354 the modes for the channels and clients on those channels, that it
6355 announced to the router when it connected to it. The protocol
6356 specification has been updated accordingly.
6358 * The silc_server_new_channel did not handle the packet coming
6359 from normal server as it normally does not send that. However,
6360 when it announces its channels it does send it. Implemented
6361 the support for that.
6363 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6364 into the file lib/silccore/id.h.
6366 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Fixed memory leaks in the functions silc_idlist_del_client,
6369 silc_idlist_del_channel and silc_idlist_del_server in the file
6370 silcd/idlist.c. All of those leaked like a sieve.
6372 * Fixed some small memory leaks in the client's function
6373 silc_client_notify_by_server.
6375 * Added functions into silcd/server.c: silc_server_announce_clients,
6376 silc_server_announce_channels and silc_server_announce_server.
6377 These functions are used by normal and router server to announce
6378 to its primary router about clients, channels and servers (when
6379 router) that we own. This is done after we've connected to the
6382 These functions effectively implements the following packet types:
6383 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6384 and SILC_PACKET_NEW_ID_LIST.
6386 * Added new functions into the silcd/packet_receive.[ch]:
6387 silc_server_new_id_list, silc_server_new_channel_list and
6388 silc_server_new_channel_user_list to handle the incoming
6389 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6391 * Added support of changing Channel ID in the function
6392 silc_server_replace_id. If the server that announces a channel
6393 to the router already exists in the router (with same name but
6394 with different Channel ID), router is responsible to send
6395 Replace ID packet to the server and force the server to change
6396 the Channel ID to the one router has.
6398 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6399 client that the Channel ID has been changed by the router. The
6400 normal server sends this to the client. Client must start using
6401 the new Channel ID as the channel's ID.
6403 Implemented handling of this new type into lib/silcclient/client.c
6404 into the function silc_client_notify_by_server.
6406 * Added new function silc_idlist_replace_channel_id into the files
6407 silcd/idlist.[ch] to replace the Channel ID.
6409 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Call silc_server_command_identify_check always when processing
6412 the IDENTIFY command in silcd/command.c
6414 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6417 send keepalive packets. The packet can be sent by clients,
6418 servers and routers.
6420 Added function silc_socket_set_heartbeat into the file
6421 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6422 If not set, the heartbeat is not performed. The actual
6423 heartbeat is implemented in the low level socket connection
6424 library. However, application is responsible of actually
6427 Added silc_server_send_heartbeat to send the actual heartbeat
6428 packet into silcd/packet_send.[ch]. Server now performs
6429 keepalive with all connections.
6431 * Added silc_task_get_first function into lib/silcutil/silctask.c
6432 to return the timeout task with shortest timeout. There was a bug
6433 in task unregistration that caused problems. TODO has been
6434 updated to include that task system must be rewritten.
6436 * The client library will now resolve the client information when
6437 receiving JOIN notify from server for client that we know but
6438 have incomplete information.
6440 * Rewrote parts of silc_server_remove_from_channels and
6441 silc_server_remove_from_one_channel as they did not remove the
6442 channel in some circumstances even though they should've.
6444 * Encryption problem encountered in server:
6446 The LEAVE command used to send the Channel Key packet to the
6447 router immediately after generating it. However, the code
6448 had earlier sent Remove Channel user packet but not immediately,
6449 ie. it was put to queue. The order of packets in the router
6450 was that Channel Key packet was first and Remove Channel User
6451 packet was second, even though they were encrypted in the
6452 reverse order. For this reason, MAC check failed. Now, this
6453 is fixed by not sending the Channel Key packet immediately but
6454 putting it to queue. However, this is more fundamental problem:
6455 packets that are in queue should actually not be encrypted
6456 because packets that are sent immediately gets encrypted
6457 actually with wrong IV (and thus MAC check fails). So, packets
6458 that are in queue should be encrypted when they are sent to
6459 the wire and not when they put to the queue.
6461 However, the problem is that the current system has not been
6462 designed to work that way. Instead, the packet is encrypted
6463 as soon as possible and left to the queue. The queue is then
6464 just purged into wire. There won't be any fixes for this
6465 any time soon. So, the current semantic for packet sending
6468 o If you send packet to remote host and do not force the send
6469 (the packet will be in queue) then all subsequent packets to the
6470 same remote host must also be put to the queue. Only after the
6471 queue has been purged is it safe again to force the packet
6474 o If you send all packets immediately then it safe to send
6475 any of subsequent packets through the queue, however, after
6476 the first packet is put to queue then any subsequent packets
6477 must also be put to the queue.
6479 Follow these rules and everything works fine.
6481 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Added new function silc_server_remove_clients_by_server to
6484 remove all client entries from ID list when the server connection
6485 is lost. In this case it is also important to invalidate all
6486 client entires as they hold the invalid server entry. This
6487 fixes fatal bug when server has lost connection and will reconnect
6490 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Made some sanity checks to silc_server_daemonise like to check
6493 whether the requested user and group actually exists.
6495 * Added sanity check to SKE's silc_ske_responder_finish to check
6496 that the public and private key actually is valid.
6498 * Invalidate the client's nickname when receiving Replace ID
6499 packet and the Client ID is being replaced. This means that the
6500 server will query the nickname if someone needs it (client)
6503 * Sort the ID Cache in client library when the ID Cache data
6504 has changed (needs sorting).
6506 * Do not allow for SILC client to create several connections to
6507 several servers. The client does not support windows right now
6508 and generating multiple connections causes weird behaviour.
6510 Irssi-silc client does support windows and can handle several
6511 connections without problems, see: www.irssi.org and SILC plugin.
6513 * Fixed some places where client was added to the IDList. The
6514 rule of thumb is following (in order to get everything right):
6515 If the client is directly connected local client then the
6516 `connection' argument must be set and `router' argument must be
6517 NULL to silc_idlist_add_client function. If the client is not
6518 directly connected client then the `router' argument must
6519 bet set and the `connection' argument must be NULL to the
6520 silc_idlist_add_client function.
6522 * The funtion silc_server_packet_send_local_channel actually did
6523 not check whether the client was locally connected or not. It
6524 does that now. Fixed a bug related to LEAVE command.
6526 * Fixed Remove Channel User payload parsing bug in server's
6527 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6529 * The server's silc_server_save_channel_key now checks also the
6530 global ID list for the channel as it might not be in the local
6531 list. Fixed a bug related to LEAVE command.
6533 * Is this the end of the [<unknown>] buglet that has been lurking
6534 around for a long time? A little for loop fix in server's
6535 silc_server_command_whois_parse that is used by both IDENTIFY
6536 and WHOIS command. At least, this was a clear bug and a cause
6537 of one type of [<unknown>] buglet.
6539 * WHOIS and IDENTIFY commands call the function
6540 silc_server_command_[whois/identify]_check function even if
6541 we are not router server.
6543 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Added --with-gmp configuration option. If set the GMP
6546 is always compiled in the SILC source tree. If not set then
6547 it is checked whether the system has the GMP3 installed. If
6548 it has then the GMP won't be compiled (the system's headers
6549 and library is used), if it doesn't have it then the GMP is
6550 compiled in the SILC source tree.
6552 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Changed RSA private exponent generation to what PKCS #1
6555 suggests. We try to find the smallest possible d by doing
6556 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6557 not security fix but optimization.
6559 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Added new config entry [Identity] to fork the server and run
6562 it as specific user and group. A patch from Bostik.
6564 * Imported Dotconf configuration library into lib/dotconf.
6565 This will be used to create the SILC configuration files later.
6566 It will appear in the distsribution after this commit.
6568 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * A big code auditing weekend happening. Auditing code for
6571 obvious mistakes, bugs and errors. Also, removing any code
6574 Removed files for being obsolete:
6576 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6577 inline in the file lib/silcutil/silcbuffer.h)
6579 o lib/silcutil/silcbufutil.c (the header has inline versions)
6581 Changed code to fix possible error conditions:
6583 o The buffer formatting routines now check that the destination
6584 buffer really has enough space to add the data. This applies for
6585 both buffer formatting and unformatting
6586 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6587 unformatting was changed to accomodate following rules:
6588 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6589 sent to the function while XXX_*STRING will not allocate or copy
6590 the data into the buffer. Instead it sets the pointer from the
6591 buffer into the pointer sent as argument (XXX_*STRING used to
6592 require that the pointer must be allocated already). This change
6593 makes this whole thing a bit more consistent and more optimized
6594 (note that the data returned in the unformatting with XXX_*STRING
6595 must not be freed now). The routines return now -1 on error.
6597 o Tried to find all code that use buffer_format and buffer_unformat
6598 and added return value checking to prevent formatting and
6599 especially unformatting errors and possible subsequent fatal
6602 o Changed ske->x and ske->KEY to mallocated pointers in
6603 lib/silcske/silcske.h. Fixed possible data and memory leak.
6605 o Added return value checking to all *_parse* functions. Fixed
6606 many memory leaks as well.
6608 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6609 so that buffer overflows would not happen. All code now also
6610 checks the return value as it can fail.
6612 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Added reconnection support to server if the normal server looses
6615 its connection to the router (for example if router is rebooted).
6616 The server performs normal reconnection strategy implemented
6617 to the server. Affected file silcd/server.c.
6619 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Added new packet type SILC_PACKET_SET_MODE that is used to
6622 distribute the information about changed modes (for clients,
6623 channels and clients channel modes) to all routers in the
6624 network. Updated the protocol specification accordingly.
6626 Added functions into silcd/packet_send.c and
6627 silcd/packet_receive.c: silc_server_send_set_mode,
6628 silc_server_set_mode.
6630 Added new files silcmode.[ch] into lib/silccore that implements
6631 the encoding and decoding of Set Mode Payload. Added new type
6632 SilcSetModePayload. Moved the definitions of different modes
6633 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6635 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Oops, a little mistake in server's connection authentication
6638 protocol. The protocol is not ended with FAILURE but with
6639 SUCCESS if the authentication is Ok. :) Affected file is
6642 * Implemented NICK_CHANGE notify handling in server in the file
6643 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6644 the local clients on the channel. After the changing nickname
6645 in router environment snhould work and the [<unknown>] nickname
6646 should appear no more.
6648 The silc_server_replace_id function that receives the Replace ID
6649 payload now sends the NICK_CHANGE notify type also in the file
6650 silcd/packet_receive.c
6652 * Changed WHOIS and IDENTIFY command to support the maximum amount
6653 of arguments defined in protocol specs (3328 arguments). This
6654 fixed a bug that caused problems when there were more than three
6657 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added extra parameter, command identifier, to the
6660 silc_client_send_command so that explicit command identifier
6663 Changed that ID list routines uses specific command identifier
6664 when sending WHOIS/IDENTIFY requests to the server so that they
6665 can be identified when the reply comes back.
6667 Affected files lib/silcclient/command.[ch],
6668 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6670 * Added `sender' argument to silc_server_packet_send_to_channel
6671 to indicaet the sender who originally sent the packet to us
6672 that we are now re-sending. Ignored if NULL. Affected file
6673 silcd/packet_send.[ch].
6675 * Added some server statistics support in silcd/server_internal.h
6676 SilcServerStatistics structure and around the server code. Also
6677 send some nice statistics information when client is connecting
6680 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6682 * Fixed channel ID decoding in server's JOIN command reply in
6683 silcd/command_reply.c
6685 * Fixed braodcasting of replace ID payload to not to send it if
6686 we are standalone server in silcd/packet_receive.c.
6688 * Fixed all channel message sending routines to not to send
6689 packets to clients that has router set, since they are routed
6690 separately in the same function earlier. Affects file
6691 silcd/packet_send.c and all channel packet sending functions.
6693 * In USERS reply, res_argv[i] are not allocated, the table
6694 is allocated. Thus changed that free the table, not its
6697 * In server's whois_check and identify_check if the client is
6698 locally connected do not send any WHOIS commands - they are not
6701 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Fixed some minor bugs in client when sending WHOIS command. The
6704 arguments was in wrong order.
6706 * Removed statis function add_to_channel from server in
6707 silcd/command.c that was previously used with the joining but
6710 * Tested USERS command in router environment successfully with two
6711 routers, two servers and two clients.
6713 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Reorganized the USERS command and command reply in client library
6716 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6717 When the command is given by user we register a pending command
6718 callback that will reprocess the command after the reply has been
6719 received from the server. When reprocessing the packet we then
6720 display the information. Thus, the USERS information is displayed
6721 now in the command callback instead of in the command reply
6722 callback. The processing of the command is same as previously
6723 when server has sent the command reply in the JOINing process.
6725 * Added to USERS command in silcd/command_reply.c to join the client,
6726 we didn't use to know about, to the channel after we've created
6727 a client entry for it. Also, for clienet we did know already still
6728 check whether it is on the channel or not and add it if not.
6730 * Removed silc_server_command_join_notify as the function and its
6733 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Changed the client's pending command handling to the same as the
6736 server's pending command handling. It is also now possible to
6737 execute command reply functions from other command reply
6738 function as the function callbacks for commands and command
6739 replies are one and same. The pending commands are not static
6740 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6741 in client connection context. Thus, pending commands are server
6742 connection specific as it is convenient.
6744 Changed the function silc_client_command_pending and
6745 silc_client_command_pending_del and added new function
6746 silc_client_command_pending_check. Removed the
6747 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6750 * Added cmd_ident, current command identifier, to the client
6751 connection context in lib/silcclient/client.h to keep track on
6752 command identifiers used in command sending. Client's command reply
6753 function handling now supports the mandatory command identifiers.
6755 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6756 funtions in client to fully support pending command callbacks.
6758 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6759 as one of the arguments to the application in the command reply
6762 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6763 before first releasing SILC but came back. Now it is removed again
6764 and should come back nomore. The FORWARDED flag was used only
6765 by the JOINing procedure by forwarding the command packet to router.
6766 Now, the JOINing procedure has been changed to more generic (due
6767 to various router environment issues) and FORWARDED is not needed
6768 anymore for anything. The protocol specification is yet to be
6771 Now, removed silc_server_packet_forward from server and the flag
6772 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6774 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Renamed NAMES command to USERS command. The NAMES was named that
6777 due to historical reasons. Now it is renamed. Also, rewrote
6778 parts of the USERS command. The nickname list is not sent anymore
6779 by the server. Only Client ID and mode lists are sent in the USERS
6780 command. Changed this also to the protocol specification.
6782 The client now resolves the names and stuff after it receives
6783 the USERS list from the server when joining to the channel.
6785 * WHOIS and IDENTIFY commands has been changed to support multiple
6786 Client ID's per command. One can now search for multiple users
6787 in the network by sending only one WHOIS or IDENTIFY command.
6788 Changed the code and the protocol specifications.
6790 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6791 uses silc_server_command_whois_parse to parse the request. */
6793 * If normal server, do not parse the WHOIS and IDENTIFY requests
6794 before sending it to the router. Saves some time.
6796 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Fixed JOIN command on client library. Wrong number of arguments
6799 used to crash the client.
6801 * Added silc_server_channel_has_global function to check whether
6802 channel has global users or not.
6804 * Added silc_server_channel_has_local function to check whether channel
6805 has locally connected clients on the channel.
6807 * The silc_server_remove_from_one_channel now checks whether the
6808 channel has global users or not after given client was removed from
6809 the channel. It also checks whether the channel has local clients
6810 on the channel anymore. If it does not have then the channel entry
6811 is removed as it is not needed anymore.
6813 * The silc_server_notify now checks on JOIN notify whether the joining
6814 client is one of locally connected or global. If it is global then
6815 the channel has now global users on the channel and that is marked
6816 to the channel entry. Also, it now saves the global client to
6817 global list who is joining and JOINs it to the channel. This is
6818 for normal server, that is.
6820 Changed silc_server_send_notify_on_channel,
6821 silc_server_packet_relay_to_channel and
6822 silc_server_packet_send_to_channel check if we are normal server
6823 and client has router set (ie. global client) do not send the
6824 message to that client, as it is already routed to our router.
6826 * Implemented LEAVE notify type handling in silc_server_notify
6829 * Tested LEAVE command in router environment successfully. Tested
6830 with two routers, two servers and two clients.
6834 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6836 * Implemented SIGNOFF notify type handling in silc_server_notify
6839 * silc_server_remove_id now removes the client entry from all channels
6840 it has joined and thusly sends SIGNOFF notify type.
6842 * Rewrote the NAMES list generation in server by removing two excess
6843 loops. The lists are created now inside one loop.
6845 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * silc_server_remove_channel_user checks now also global list
6848 for channel and client.
6850 * silc_server_new_channel_user checks now both local and global
6851 list for channel and client. Fixed a bug in client id decoding.
6852 Used to decode wrong buffer.
6854 * silc_server_channel_message checks now both local and global
6855 list for channel entry.
6857 * Tested channel joining (hence JOIN) in router environment
6858 successfully. Tested with two routers, two servers and two
6861 * Tested channel message sending in router environment successfully.
6863 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added silc_server_save_channel_key into server.[ch] to save the
6866 received channel key in Channel Key payload processing. It is
6867 also used in JOIN command reply handling.
6869 Equivalent function silc_client_save_channel_key added into
6870 client.[ch] into client library.
6872 * Changed JOIN command reply to send information whether the channel
6873 was created or not (is existing already) and the channel key
6874 payload. Changed protocol specs accordingly.
6876 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6877 the request was sent by ID and not by nickname. Crashed on
6880 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6883 now correctly save the received data.
6885 * silc_server_free_sock_user_data now notifies routers in the
6886 network about entities leaving the network.
6888 At the same time implemented functions silc_server_remove_id
6889 and silc_server_send_remove_id to receive and send REMOVE_ID
6890 packets. The packet is used to notify routers in the network
6891 about leaving entities. The ID removed will become invalid in
6894 * Added function silc_idlist_del_server into server. Removes and
6895 free's server entry from ID list.
6897 * silc_server_private_message function now checks, if we are router,
6898 that the destination ID really is valid ID, naturally.
6900 * In router when NEW_ID packet is received (for new client) the
6901 hash of the Client ID is saved in the ID Cache but the
6902 client->nickname is set to NULL, instead of putting the hash
6905 IDENTIFY command now also checks that client->nickname must be
6906 valid. If it is not if will request the data from the server who
6907 owns the client. Added new function
6908 silc_server_command_identify_check.
6910 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6911 to set the command to already allocated Command Payload.
6913 * Tested private message sending in router environment with two
6914 routers, two servers and two clients. Fixed minor bugs and now
6917 * Fixed segfault from client's NAMES command. Used to crash if
6920 * Forwarded packets must not be routed even if it is not destined
6921 to the receiver. Changed server code comply with this.
6923 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Added `require_reverse_mapping' boolean value to ServerParams
6926 structure. If TRUE (not default) the server will require that
6927 the connecting host has fully qualified domain name.
6929 If the reverse mapping is not required and hostname could not be
6930 found the IP address is used as hostname.
6932 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Implemented version string checking to both client and server.
6935 The check is incomplete currently due to the abnormal version
6936 strings used in development version of SILC.
6938 * Changed all command functions in server to use the new
6941 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * Changed char *data to unsigned char *data in ID Cache system to
6944 support binary data as ID Cache data. Changed code to support
6945 binary data in lib/silccore/idcache.c.
6947 * Renamed silc_server_packet_relay_command_reply to
6948 silc_server_command_reply as it is normal packet receiving
6949 function. Rewrote the function to accept command replys for
6950 servers and not only for clients.
6952 * Mark remote router always as registered server if we are connecting
6953 to it. Otherwise, commands sent by the router to us are ignored.
6955 * All ID List find routines now returns the ID Cache Entry pointer
6956 as well if requested.
6958 * WHOIS command works now in router environment, tested with two
6959 routers, two servers and two clients.
6961 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6962 in router environment (as it is almost equivalent to WHOIS) but
6963 hasn't been tested thoroughly. Added new functions:
6965 silc_server_command_identify_parse
6966 silc_server_command_identify_send_reply
6967 silc_server_command_identify_from_client
6968 silc_server_command_identify_from_server
6970 * Disabled route cache adding because adding two different ID's with
6971 same IP replaces the old cache entry thus giving wrong route.
6972 The entry->router->connection is always the fastest route anyway
6973 so route cache may not be needed. Of course, new routes maybe
6974 established after receiving the ID when the entry->router->connection
6975 might not be anymore the most optimal.
6977 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Add route cache for received ID for fast routing.
6981 * Added silc_server_packet_route to route received packet on router
6982 that is not destined to us.
6984 * Renamed silc_server_get_route to silc_server_route_get.
6986 * Added id_string and id_string_len fields into SilcServer to
6987 include encoded ServerID for fast comparing without excess
6988 encoding of the ID's.
6990 * Cleaned up WHOIS command on server side. Added following static
6993 silc_server_command_whois_parse
6994 silc_server_command_whois_check
6995 silc_server_command_whois_send_reply
6996 silc_server_command_whois_from_client
6997 silc_server_command_whois_from_server
6999 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7000 arguments in command replies. All command functions should be
7001 updated to use this macro.
7003 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Minor typo fixes on command reply handling on server.
7007 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Added silc_server_command_add_to_channel internal routine to add
7010 the client to the channel after router has created the channel and
7011 sent command reply to the server.
7013 * Added generic silc_server_send_command to send any command from
7016 * Use static buffer with ID rendering instead of duplicating data.
7018 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Fixed a channel user mode bug when joining to a channel server gave
7021 everybody channel founder rights, oops.
7023 * We mark ourselves as the router of the incoming server connection
7024 if we are router ourselves. This way we can check in some packet
7025 sending functions whether it is locally connected server. For
7026 incoming router connections we put NULL.
7028 * For router sending packets locally means now always sending the
7029 packet cell wide; to local clients and local servers. For normal
7030 server sending packet locally means sending it to only local
7033 * Fixed the JOIN command to really work in router environment. If the
7034 channel is created it is always created by the router. Router is
7035 also responsible of making the initial joining to the channel,
7036 sending JOIN notify to the sending server and distributing
7037 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7038 does not exist server doesn't do anything else but forward the
7039 command to the router which performs everything.
7041 * Added silc_server_send_channel_key function to send the Channel Key
7044 * Added silc_server_create_channel_key to create new channel key. The
7045 channel key is now re-generated everytime someone joins or leaves
7046 a channel, as protocol dictates. Note: channel->key_len is the
7049 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7052 packet_receive.[ch] to separate packet sending and receiving
7053 routines. The server.[ch] now includes everything else including
7054 actual packet processing (writing and reading data) and other
7057 Renamed silc_server_private_message_send_internal to
7058 silc_server_send_private_message. The routine is still though
7059 used only to relay private messages as server does not send
7060 private messages itself.
7062 Renamed silc_server_new_channel to silc_server_create_new_channel
7063 and added new function sicl_server_new_channel that handles the
7064 incoming New Channel packet. Added also new sending function
7065 silc_server_send_new_channel to send New Channel Payload.
7067 * Added new function silc_server_notify to process incoming notify
7068 packet to the server/router. Server may then relay the notify
7069 to clients if needed.
7071 * Added new function silc_server_new_channel_user to process incoming
7072 New Channel User packet. Router will redistribute the packet and
7073 send JOIN notify to its local clients and locally connected servers
7074 if needed. Normal server will send JOIN notify to its local client
7075 on same channel when received this packet. Added also corresponding
7076 sending function silc_server_send_new_channel_user to sent the
7079 * Added boolean route argument to send_notif_to_channel and
7080 packet_send_to_channel functions to attempt to route the packet
7081 if it is TRUE and send only locally if it is FALSE.
7083 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * silc_server_replace_id now broadcasts the received replace ID
7086 packet if it is not broadcast packet already. The router must
7087 broadcast to inform other routers about changed ID.
7089 * Added backpointer to server's router into SilcServer context in
7090 silcd/server_internal.h.
7092 * Fixed silc_server_packet_broadcast to send correct broadcast
7095 * The channel key is now distributed to the local client as soon
7096 as it is received from the router (in router environment) so that
7097 no other packet may be sent for the channel until client has
7100 * silc_server_remove_channel_user now broadcasts the received
7101 Remove Channel User packet if it is not broadcast packet already.
7102 The router must broadcast to inform other routers about removed
7105 * Added users field into SilcPacketContext that is a reference count
7106 of the context. One can increase the reference count by calling
7107 silc_packet_context_dup which is now changed to just increase the
7108 reference count instead of duplicating the data. The reference
7109 count is decresed by calling silc_packet_context_free that will
7110 free the data after the reference count hits zero.
7112 For now on the packet context and everything allocated into it
7113 (including the raw packet from network) must be freed by calling
7114 the new silc_packet_context_free function. Added also new function
7115 silc_packet_context_alloc that must be used now to allocate the
7116 context. This also means that if a routine is asynchronous from
7117 silc_[client/server]_packet_parse_type the packet context must
7118 be duplicated by calling silc_packet_context_dup. Otherwise it
7119 gets free'd after silc_[client/server]_packet_parse_type returns.
7120 Also, one must remember that if packet is duplicated then its
7121 reference count must be decresed by calling the free function as
7122 many times as it was duplicated.
7124 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7125 from both client and server.
7127 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Made joining to a channel working in router environment.
7131 * Cleaned up JOIN command on server side and create function
7132 silc_server_command_join_channel internal routine to make the
7135 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Changed silc_command_pending list to SilcDList. Also, added
7138 `ident' field to SilcServerCommandPending structure to identify
7139 the reply and to call correct callback.
7141 Added silc_server_command_pending_check function to replace the
7142 corresnponding macro. The silc_command_pending list is not
7145 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7146 to set identifier to previously allocated Command Payload. It
7147 is used to set identifier for command when resending Command
7150 * Added silc_command_payload_encode_payload to encode Command
7151 Payload buffer from SilcCommandPayload structure.
7153 * Added silc_argument_payload_encode_payload to encode Argument
7154 payload buffer from SilcArgumentPayload structure.
7156 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Changed WHOIS command to support router connection on server side.
7159 The whois request is always sent to router unless the server is
7160 standalone server. After server has received the reply from the
7161 router will it send the reply to the client.
7163 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7164 broadcast received broadcast packet. The function is used only
7165 by router. The broadcast packet is always sent to the router's
7168 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7169 render given ID to printable string, for log files for example.
7171 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Made basic router to router connections working. At least they
7174 can now connect to each other but nothing really works the way
7175 they are supposed - yet.
7177 * Added new initiator token to RouterConnection configuration
7178 file in silcd/serverconfig.[ch]. It is used to tell whether we
7179 are the initiator to the remote router or whether we'll expect
7180 the other end to connect.
7182 * Moved registering of listener task to silc_server_init, hence
7183 the server starts listenning as soon as it is run, even if it
7184 does not have connections to other routers. Let's see how well
7187 * Changed default connection retry timeouts for more suitable in
7190 * Removed cipher and such arguments from silc_idlist_add_client
7191 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7192 Added new function silc_idlist_add_data to add the keys and stuff
7195 * Added SilcIDListData structure and added it to SilcClientEntry
7196 and SilcServerEntry as their first field in the structure. This
7197 way we can explicitly cast the ID entries to the SilcIDListData
7198 structure and get common data for the entries. In past, we had
7199 to first check what type of connection it is and then cast it to
7200 correct ID entry type. Now, we can directly cast the opaque
7201 pointer to the SilcIDListData (no matter what ID entry it actually
7202 is) and get the data needed.
7204 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7207 in some circumstances even if threre were timeout tasks, though not
7208 IO tasks, but tasks anyway. Now fixed.
7210 * Defined SilcServerConnection structure to hold connection specific
7211 stuff about directly connected servers and routers. The definition
7212 is currently in silcd/server_internal.h. I thought about having
7213 a bit more important role fro this struct but for now it is used
7214 only when connecting to other server (or router actually).
7216 * Added connecting retry support in server when connecting to
7217 router(s). The retry feature implement exponential backoff
7218 algorithm. Also, added SilcServerParams structure to hold default
7219 parameters for server. For now, it include these retry settings
7220 and are hard coded. After server is moded to be as Silc Server
7221 Library this structure will be more important.
7223 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Changed client librarys channel->clients table to SilcList and
7226 changed code accordingly.
7228 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Changed client's channel table to SilcList and changed code
7231 accordingly. Also changed SilcChannelClientEntry to include back-
7232 pointer to the channel so that client entry can use that structure
7233 as list as well and we have fast cross-reference to the channel.
7234 This change dramatically decreased the complexity of channel
7235 handling with client entry and vice versa (removed one extra
7236 loop when searching for channel entry from many functions).
7238 * Changed server->sim from table to SilcDList and changed code
7241 * NAMES command can now be used from user interface. It will show
7242 the user list on the channel, neatly.
7244 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7245 Code now saves realname of the user if it becomes available.
7247 * Renamed configure.in to configure.in.pre and made ./prepare
7248 script to automatically add correct version string to
7249 configure.in which it creates from configure.in.pre.
7251 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7253 * NAMES command reply now shows users mode with the nickname when
7256 * Moved silc_client_ch[u]mode[_char] functions from
7257 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7258 place sucks, they are utility functions and should be in some
7261 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7263 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7266 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7270 * Added TRQ (efficient deque and list library) into lib/trq. This is
7271 a very good list library that is currently used in the SILC. Defined
7272 SilcList API over the library because I didn't like the API very
7273 much. See lib/trq/silclist.h for the API and examples of how to
7274 use the API. Fixed various places in the code to use the new
7275 SilcList API. The SilcList is meant for lists that has a structure
7276 already defined as a list. It is not suitable to add just some
7277 context to the list (in TRQ, the context is the list actually).
7279 So, I defined SilcDList that can be used for the purpose where
7280 predefined list structure does not exit. This can be used as
7281 such list. Now some context just can be added to the SilcDList.
7282 Currently this list is not used in the SILC just yet, though there
7283 are a lot places where this can replace dynamically allocated
7284 tables and I will fix these places, later, to use SilcDList.
7285 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7286 and use TRQ internally).
7288 Also fixed some annoying warning messages that the original TRQ
7289 code generated. Also minor changes to TRQ's Makefile.in.
7291 * Added support for querying by Client ID to both WHOIS and
7292 IDENTIFY commands into server, as required by the protocol.
7294 * Removed method function pointers from SilcBuffer structure. They
7295 weren't used to anything and just increased the context size for
7296 no good reason. This change also made silc_buffer_alloc and
7297 silc_buffer_free functions inline functions.
7299 * Disabled command flooding detection support until it's fixed so
7300 that it accepts commands in but does not execute them more than once
7303 * Added silc_net_localhost(), to return local hostname, into
7304 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7305 that must be initialized before calling silc_client_init.
7307 * Added new function: silc_server_send_notify_on_channels to send
7308 notify messages to all channels client has joined. It is assured
7309 that the message is sent only once per client.
7311 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7312 lib/silcutil/silcutil.[ch] as silc_format function. The new
7313 function is generic and is used by server as well, not only by
7314 the logging routines.
7316 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7317 the provided version string was not acceptable. Added new function:
7318 silc_ske_check_version into lib/silcske/silcske.h. The function
7319 must be implemented by the application (client or server) and it
7320 does not reside in the SKE library. The function checks the version
7321 string remote end sent.
7323 * Added back pointers (to opaque context and to SilcSocketConnection)
7324 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7326 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7327 duplicate packet context structure.
7329 * Changed `notify' client operation to send same arguments as client
7330 receives from server except for ID's. ID's are mapped to correct
7331 ID entry and that is returned. Also, if channel entry is not sent
7332 by server but the notify is for channel the channel entry is sent
7333 to application (otherwise application doesn't know that it is for
7334 channel (library gets it from packet's Destination ID)).
7336 * Added silc_client_remove_from_channels into client library to
7337 remove a client from all channels it has joined to. Used when
7338 received SIGNOFF notify from server. Added also new function
7339 silc_client_replace_from_channels to replace old ID entry with
7340 new ID entry on all channels. Used when received NICK_CHANGE
7343 * Fixed ID Cache list handling in silc_idlist_get_client in
7344 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7345 to get (or query) client by ID.
7347 * Updated TODO list.
7349 * Added connection authentication status message defined by the
7350 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7351 support for these into the code in client and server side.
7353 * Added generic function silc_client_send_command to send any command
7354 with variable argument list. Application should use this function
7355 to send commands if the command functions provided by the library
7356 does not suite for the application's user interface needs.
7358 * Added new `failure' client operation. Application is notified about
7359 received failure packet if client is executing a protocol. In this
7360 case the protocol's execution has failed.
7362 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7363 is required by the protocol.
7365 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7366 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7369 * Added status flag to SilcSKE object to indicate realtime status
7370 of the SKE protocol.
7372 * Application receives now exactly same command reply arguments as
7373 the library receives from server. However, if ID is received the
7374 corresponding ID entry is returned to the application (eg. Client
7375 ID is mapped to correct SilcClientEntry entry and that is returned).
7376 Changed command_reply client operation due to this change.
7378 * Changed all ID's in commands and in command replys as ID Payloads.
7379 Change affected both client and server side codes.
7381 All ID's sent in SILC network (with execption of ID's in SILC
7382 Packet header) are sent in ID Payload to support variable length
7385 * Server now notifies nick changes and notifies all clients on
7386 the channels about the new nickname (about the new Client ID,
7389 * Implemented CMODE command to change channel modes. Supports all
7390 channel modes defined by the protocol specs except ban and invite
7391 lists. (Also, private channel key mode is supported but support for
7392 setting private channel key in client is missing, thus, this mode
7393 has no effect on client side (except that server requires that the
7394 client uses private channel key and normal channel traffic does not
7397 Also, invite mode works per se, but INVITE command does not work
7398 yet correctly, so you can set channel as invite only channel but
7399 inviting clients to the channel does not work (it is yet to be
7400 thought what's the best way to do it).
7402 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7403 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7404 Implemented CUMODE command to change user's mode on the channel.
7405 Supports all modes defined by the protocol specs.
7407 * Added NAMES command reply to return users modes on the channel.
7409 * Removed unnecessary and slow ciphers from lib/silccrypt.
7411 * Set SO_KEEPALIVE option to connection sockets by default.
7413 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7415 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7416 redefined the Notify Payload into protocol specs.
7418 * Added silc_id_payload_parse_id to get ID directly from raw
7421 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7423 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7424 accept searching by Client ID as well.
7426 * Added support for LEAVE and SIGNOFF notify types in client library.
7428 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7429 to parse ID Payload from raw data.
7431 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Added flags parameter into silc_ske_assemble_security_properties
7434 function in lib/silcske/silcske.[ch].
7436 * Changed notify client operation to fit better for notify messages
7437 sent by server. The notify payload received from server is now
7438 passed to the application (after parsing it to SilcNotifyPayload).
7439 It is application's responsibility to retrieve the arguments
7440 from the payload and show the message the way it wants. The message
7441 sent by server is implementation specific.
7443 * Changed public keys to comply with the protocol specification.
7444 Old public keys are not supported anymore and are not compatible.
7446 * Removed nickname from Channel Payload as the latest draft removed
7447 it. The client must resolve the nickname from the NAMES command
7448 reply received when it joined the channel.
7450 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7452 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * Fixed some errors in protocol specification drafts.
7456 * Created lib/silccore/silcnotify.c to implement Notify Payload
7457 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7458 generic payloads described by protocol specifications. The file
7459 includes implementations for ID Payload and Argument Payload.
7461 * Changed Command Payload implementation to use the new Argument
7462 Payload. Changed command_xxxx_payload to command_payload_xxxx
7463 to comply with SILC coding conventions.
7465 * Added suppport for Argument Payload handling in Notify Payload
7466 implementation as protocol requires it. Added the new support
7467 into server and client lib as well.
7469 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7471 * Added support for multiple nicknames on same channel. [n] is
7472 added locally to the nickname if there are more than one same
7473 nicknames on the channel.
7475 * Server now sends all nicknames that matched WHOIS request.
7476 Client also shows the list received from server.
7478 * Added TOPIC command to client side. User can now set and show
7479 current topic on channel.
7481 * Added MOTD command to client and server. Also, server sends the
7482 motd when client connects to the server.
7484 * Changed version strings to comply ISO 8601.
7486 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * Fixed protocol error handling in client library. It should now
7489 cope even if the SKE fails for some reason.
7491 * Made new protocol specification drafts for submitting to IETF.
7493 * Implemented TOPIC command to server in silcd/command.c.
7495 * Added two new notify types into lib/silccore/silcnotify.h:
7496 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7497 notify nickname change and topic setting/change on a channel.
7499 * API change of command_reply operation in client library. The
7500 application gets now the status type received from server as well.
7502 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7504 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7506 * Cras fixed and optimized the packet handling even further and
7507 it should work now. Minor change to the prototype of function
7508 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7510 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7512 * Added new function into lib/silcutil/silcschedule.[ch]:
7513 silc_schedule_with_fd to select() a specified fd. The function
7514 returns after timeout expires or data arrives or goes. The
7515 function is used by packet routines to wait that all data is
7516 received from network.
7518 * Fixed data reading from network in lib/silccore/silcpacket.c.
7519 The code now assures that all data is read from the fd and then
7520 continues packet processing. This was a bug fix since the code
7521 used to drop some data in some circumstances.
7523 * Added new function into lib/silcclient/client.[ch]:
7524 silc_client_start_key_exchange to start key exchange after
7525 connection has been established to server. The code internally
7526 now uses this funtion but its main purpose was to provide it
7527 for applications that perform their own connecting. After
7528 application has created a connection it merely calls this
7529 function to start the key exchange between client and server.
7530 The library takes care of everything else after that.
7532 Updated also lib/silcclient/README to explain the usage of
7535 * Do not send to application information that connection has
7536 been established. Application gets notified it by connect
7539 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Applied cras's patch to add silc_schedule_one function. The
7542 function runs scheduler once and returns.
7544 * Fixed the scheduler after cras messed it up. The timeout
7545 handling works now as it's supposed to work.
7547 * Added into lib/silccore/ silcnotify.h to include notify
7548 message types support. Changed silc_server_send_notify*
7549 functions, in server.[ch], to support those new notify types.
7550 Added the support for the notify types into client library,
7551 as well. Added new notify client operation into ops.h in
7554 * Changed silc_server_packet_send_to_channel to send normal
7555 packets instead of just channel message packets. The function
7556 is now used to send the notify packets to channels. It is not
7557 used to send channel message packets anymore, as server never
7560 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7561 va_arg()s as it seems to require it nowadays. I guess, if SILC
7562 is compiled with older va_arg() the new code should work anyway.
7564 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7566 * Splitted core library. Core library (lib/silccore) includes
7567 now only SILC protocol specific core (and common) components.
7568 Created new utility library (lib/silcutil) that includes more
7569 generic purpose stuff. The stuff for util library was taken
7570 from the old core library. This was minor and easy split.
7572 * Created SILC Client Library (lib/silcclient) that includes
7573 implementation of the SILC client without user interface. This
7574 was major move from silc/ directory. The code has been changed
7575 so that it is transparent towards the user interface. The
7576 silc/ directory includes now the same user interface as before
7577 and it uses the new client library. Read lib/silcclient/README.
7578 Basicly, the client library performs everything else related
7579 to SILC except user interface handling. Also, configuration
7580 files are considered to be part of user interface and library
7581 does not handle them.
7583 This change also changed a lot of structures, function naming etc.
7584 Most important change was that SilcClientWindow object was
7585 renamed to SilcClientConnection in the client library. Created
7586 also new file lib/silcclient/ops.h. Also added new files
7587 silc/local_command.[ch] and silc/client_ops.[ch].
7589 All these changes were made to make it easier for user interface
7590 designers to create what ever user interface for the SILC client
7593 It is also expected that the server will be moved to lib
7594 directory as well and SILC Server Library will be created;
7595 sometimes in the future.
7597 * Removed Local commands from lib/silccore/silccommand.h as
7598 they are application specific and new client library does not
7599 handle any of those anymore.
7601 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7602 old client implementation in silc/.
7604 * Added support for callback functions in SILC_LOG_* macros.
7605 Application can now set its own callbacks that will be called
7606 instead of using the default functions that will always print
7607 the debug messages to stderr (or stdout). Also, debugging can
7608 now be disabled by setting silc_debug to FALSE and re-enabled by
7609 setting it to TRUE. Note, that logging will still work even
7610 if debugging is disabled.
7612 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7613 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7614 silc_log_reset_debug_callbacks.
7616 * To enable debugging in silc client one must give now -d
7617 option on command line.
7619 * Changed silc_schedule_init to automatically allocate task queues
7620 if they are not allocated before calling it.
7622 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Added GMP 3.1 into math library.
7626 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7629 a channel in SILC network. The packet is used by servers and
7630 routers to notify other routers that user has left a channel.
7631 This little feature was missing until now. Added the feature
7632 to protocol specification as well.
7634 Added functions: silc_server_send_remove_channel_user and
7635 silc_server_remove_channel_user into server.[ch].
7637 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7638 lib/silccore/silcpacket.h. However, they are not implemented
7641 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7643 * Fixed joining to a channel and sending channel messages
7644 between server and router. The channel message sending should
7645 now work inside a cell.
7647 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7649 * Fixed the private message sending between server and router.
7650 The private message sending should now work inside a cell.
7652 * Added silc_server_replace_id into server.[ch] to replace
7653 existing ID in the SILC network.
7655 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7656 and silc_idlist_replace_server_id into idlist.[ch] in server.
7658 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7660 * Fixed the server to server connections. Server can again now
7661 connect to router. Router to router connections probably does
7664 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7666 * Added dynamic protocol registering support. Now protocols can
7667 registered and unregistered on the fly. Patch by cras.
7669 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7671 * Added lib/contrib directory to hold routines that some platforms
7672 don't have but are needed by SILC.
7674 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7675 into lin/contrib to provide getopt() and getopt_long() for
7676 those who don't have it.
7678 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7680 * Added AWAY command to client. When away message is set and
7681 client receives a private message packet the client automatically
7682 replies to the sender with the away message.
7684 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7685 bug seemed to be the cause of recent problems when compiling
7688 * Added version detection support to SKE protocol specification
7689 and added the new changes to the SKE implementation as well.
7690 There were other minor changes in the SKE protocol as well.
7692 Many changes in lib/silcske/silcske.[ch] and in
7693 lib/silcske/payload.[ch].
7695 * Added ^U functionality, clear input line. Patch from cras.
7697 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7699 * Mainly small bugfixes on core library. Fixed some debugging
7700 logging and buffer overflow in silclog.c.
7702 * Updated config.sub and config.guess on the distribution tree.
7704 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7706 * Added command lagging support in server. Client may execute
7707 commands now only once in two seconds.
7709 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Optimized packet reception. MAC computation and checking is now
7712 also more optimized. A lot previously duplicated code is now
7713 used as generic by both client and server.
7715 * Fixed key pair generation in clientutil.c
7717 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7719 * Added into lib/silccore/silcbufutil.[ch] new function;
7720 silc_buffer_realloc.
7722 * Moved generic packet sending/encryption functions to
7723 lib/silccore/silcpacket.[ch] from client and server. Some
7724 rewriting of the functions.
7726 * Moved all generic packet reception/decryption functions to
7727 lib/silccore/silcpacket.[ch] from client and server. The
7728 packet processing is now much cleaner in both client and server.
7729 These were major changes in both client and server.
7731 * Created many common functions in server to do packet sending.
7732 Previously code were duplicated a lot, this has been removed
7735 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7737 * Rewrote major parts of the ID cache system. Don't know
7738 whether it is better now or not but at least the API is more
7741 * Major rewrite on ID cache stuff on client because of the ID
7742 cache API changes. Added idlist.c to client.
7744 * Also major rewrite on ID cache stuff on server as well.
7745 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7746 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7747 in hand, instead they are all put into the ID cache system now.
7748 All server_idlist_* routines uses ID cache now instead of
7749 traversing its own lists (those lists does not exist anymore).
7750 SilcIDList though still exists. Also, SilcXXXEntry's are
7753 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * Finally made the SKE implementation compliant to the protocol
7756 specification. All mp integers are now binary encoded as
7757 opposed being HEX encoded.
7759 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7762 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7763 functions: silc_[encode/decode]_pem. Also added function
7764 silc_encode_pem_file to PEM encode with newlines ('\n') for
7767 * SILC public keys are now encoded either PEM or binary. Same
7768 option is for private keys as well. By default private keys
7769 are binary encoded and public keys PEM encoded. Silly HEX
7770 encoding were removed.
7772 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7773 function to create fingerprints.
7775 * Fixed a bug in SHA1; does not change the original data anymore.
7777 * Partly implemented INFO command on client and server side.
7778 Fixed CLEAR command. Changes to SERVER command; show current
7779 server(s) when giving command without arguments. Added
7780 VERSION command to client.
7782 * Added check to server that unregistered connections cannot
7783 execute commands (unless it is specificly allowed).
7785 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * Fixed screen refresh.
7789 * Fixed channel joining bug from client. On some circumstances
7790 client tried to join to a channel it had already joined.
7792 * Added public key verification process into client's protocol.c.
7793 The client now verifies the public key from user and saves
7794 it into ~./silc/serverkeys/ directory.
7796 Added into: clientutil.[ch]: silc_client_verify_server_key.
7798 * Changed SKE protocol's silc_ske_initiator_finish function
7799 to accept callback function that verifies the received public
7800 key. Removed old silc_ske_verify_public_key function.
7802 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7804 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7805 silc_pkcs_private_key[_data]_set.
7807 * Made the password and public authentication more cleaner in
7808 server's protocol.c.
7810 * Removed historic and obsolete protocol `channel_auth' from
7811 both client and server.
7813 * Removed wrong way of sending command status messages from
7814 server to client in server's command.c. The old way violated
7815 protocol specification.
7817 Changes to silccore/silccommand.[ch]: removed
7818 silc_command_encode_status_payload -> not needed anymore,
7819 changed silc_command_encode_payload_va to accept extra
7820 argument on variable argument list. The argument type must
7821 now be provided to the function. Also, added new function:
7822 silc_command_encode_reply_payload_va which is same as
7823 normal command_encode_payload_va except command status type
7824 is provided as extra argument.
7826 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7828 * Added ~./silc directory handling. The directory includes the
7829 public and private keys for the client.
7831 Added silc_client_check_silc_dir, silc_client_create_identifier
7832 and silc_client_load_keys.
7834 * Implemented SILC protocol compliant public key. Added public
7835 and private key saving to and loading from files.
7837 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7838 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7839 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7840 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7841 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7843 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7844 silc_pkcs_load_[public/private]_key.
7846 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Added silc_server_get_route (route.[ch]) to get connection
7849 data for the fastest route for given ID.
7851 * Implemented INVITE command on client and server. The command
7852 were re-defined in the SILC Protocol Specification and the
7853 implementation now complies with the specification.
7855 * Implemented PING command on client and server.
7857 * Implemented NAMES command on client and server. The server side
7858 supports currently only normal server not router server yet.
7859 Some changes to NAMES definition in SILC protocol specification.
7861 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Implemented LEAVE command on client and server.
7865 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7866 again. This change was made to the protocol as well. Server
7867 should not violate the protocol specification anymore.
7869 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7871 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7872 was tested. SOCKS4 was not but should work anyway.
