1 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added automatic referencing of config context in the
4 silc_server_config_alloc, and automatic unreferencing in the
5 silc_server_config_destroy. Affected files are
6 silcd/serverconfig.[ch], silcd/silcd.c.
8 * Fixed the silc_log_quick handling in the logging routines.
9 It didn't log quickly when it was TRUE. Affected file is
10 lib/silcutil/silclog.c. Also the flush delay was set even
11 if it was 0 in config file. Affected file is
14 * Added support for changing key pair of the server in rehash.
15 Affected file silcd/server.c.
17 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Fixed the TOPIC_SET notify to not cras. It changed the topic
20 too early, before getting the channel entry. Affected file
21 is silcd/packet_receive.c.
23 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
25 * Added functions silc_server_config_[ref/unref], these are used
26 to prevent that the config object is destroyed.
28 No longer directly affect global variables silc_log_quick and
29 silc_log_delay, they are first cached inside the config object
30 and then applied with silc_server_config_setlogfiles().
32 silc_server_config_set_defaults() is now internal to
33 serverconfig.c, there are no reasons to show this internal stuff
36 Affected files are silcd/serverconfig.[ch].
38 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
39 fprintf's to stderr, since some code may be executed again after
40 the server went into the background. Affected files are
43 * Added rehash support. Added function silc_server_rehash() that
44 will perform all the basic tasks of the rehashing procedure.
46 * Added command line option `-x, --hexdump'. This will enable the
47 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
48 The option `--hexdump' implies `--debug'.
50 * Fixed a bad bug in the logging APIs (silcutil library) where
51 the application would crash after calling silc_log_reset_all().
53 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
55 * Fixed the KICKED notify handling in client library to
56 correctly remove the channel and all entries from the
57 channel when I was kicked. This bug crashed the client.
59 Fixed yet another but in KICKED notify handling to remove
60 the kicked client correctly from the channel.
62 Affected file is lib/silcclient/client_notify.c.
64 * Fixed a minor bug in looking up correct client entry
65 in KICKED notify in server. Affected file is
66 silcd/packet_receive.c.
68 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
69 sources correctly to distribution. Fixes --with-gmp option.
71 * Removed the manual rehashing from ID Cache, and changed it
72 to use the SILC Hash Table's auto rehash feature. Affected
73 file is lib/silccore/silcidcache.c.
75 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
77 * Fixed a bug in the silc_client_nickname_format function that
78 handles the multiple same nickname formatting. Two clients
79 with same nickname caused problems after the first one left
80 and rejoined. It didn't format the nickname correctly.
81 Affected file is lib/silcclient/idlist.c.
83 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
85 * Don't change the topic if olod topic is same as new one.
86 Affected file is silcd/packet_receive.c.
88 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
90 * Added cross-reference support to the SILC Documentation
91 generator. All types across all HTML files are now cross-
92 referenced. Affected files util/robodoc/generator.c and
93 scripts/silcdoc/silcdoc.
95 * Added file lib/silcutil/silctypes.h to include all the
96 arithmetic type definitions and some macros. Removed
97 includes/bitmove.h and moved macros to silctypes.h.
99 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
103 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Added `type' argument to silc_id_payload_parse_id function which
106 now returns the type of the ID to the sent pointer. Affected
107 file is lib/silccore/silcid.[ch].
109 * Added check for CMODE_CHANGE notify type that mode change is
110 allowed by the sender. Affected file silcd/packet_receive.c.
112 * Added check for CUMODE_CHANGE notify type that mode change is
113 allowed by the sender. Affected file silcd/packet_receive.c.
114 Added the ID type as CUMODE_CHANGE notify type as argument
115 to the `notify' client operation. Affected files are
116 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
118 * Added function silc_client_add_server to the client library.
119 Added support for resolving also channel and server info when
120 received unknown entity in notify packet. Affected files are
121 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
123 * Added function silc_command_get_status to return the command
124 status from the command reply's argument payload. Affected files
125 are lib/silccore/silccommand.[ch].
127 * Added check for KICKED notify type that the kicking is
128 allowed by the client. Affected file silcd/packet_receive.c.
130 * Created function silc_get_input which can be used to get input
131 (echo on or off) from user on command line. Affected files are
132 lib/silcutil/silcutil.[ch].
134 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Optimized silc_server_packet_relay_to_channel function.
137 Added new function silc_channel_message_payload_encrypt which
138 can be called directly if channel message payload needs to
139 be encrypted and is already encoded (no need to call _encode
140 function). Packet relaying is now done by router without any
141 extra memory allocations. Affected files are
142 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
145 * Fixed the INVITE notify handling. It took wrong arguments
146 as invite list and invite delete. Affected file is
147 silcd/packet_receive.c.
149 * Added check for TOPIC_SET notify type that the topic change is
150 allowed by the client. Affected file silcd/packet_receive.c.
152 * Added check for INVITE notify type that inviting is allowed by
153 the client. Affected file silcd/packet_receive.c.
155 * Changed the silc_server_client_on_channel to return the
156 SilcChannelClientEntry as well. Moved the function
157 silc_server_check_cmode_rights to server_util.[ch].
158 Affected files are silcd/server_util.[ch], silcd/command.c.
160 * Added function silc_server_check_umode_rights to check whether
161 changing client's user mode is allowed. Added check for
162 UMODE_CHANGE notify type that the umode change is allowed
163 by the client. Affected files are silcd/server_util.[ch],
164 silcd/packet_receive.c and silcd/command.c.
166 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
169 ID length. It ignored that ID can be IPv6 based as well.
170 Affected file lib/silccore/silcpacket.h.
172 * Fixed the silc_id_id2str and silc_id_str2id to take the
173 IPv6 address offset's into consideration. Affecte file is
174 lib/silccore/silcid.c.
176 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
178 * Fixed the internal Unix scheduler functions to check for
179 NULL context they may receive. The affected file is
180 lib/silcutil/unix/silcunixschedule.c.
182 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
184 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
185 can specify different directory with --home command line
186 parameter. Affected files irssi/src/silc/core/client_ops.c,
189 * SILC-specific commands aren't now executed if the active server
190 isn't of SILC-type, so there won't be problems with having
191 IRC and SILC protocol support in same client. Affected files
192 irssi/src/silc/core/silc-channels.c, silc-servers.c,
195 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Improved the signal support in SILC Schedule. Added new
198 function silc_schedule_signal_call which is used by application
199 to mark a signal to be called. It is now safe to perform
200 any kind of tasks in signal callbacks since it is guaranteed
201 that the application specified signal callback is called
202 after the signal is over. Affected files are
203 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
205 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Added `name' field to SilcChannelPrivateKey to represent
208 application given name for the key. Moved also the context from
209 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
210 Added the `name' argument also to the function
211 silc_client_add_channel_private_key.
213 Added function silc_client_current_channel_private_key to set the
214 current channel private key in use.
216 Added "change" command to KEY command which can be used to change
217 the current channel private key. Bound the command also to
220 Also affected files lib/silcclient/client_channel.c,
221 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
223 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
225 * Added silc_rng_get_byte_fast function in to the
226 lib/silccrypt/silcrng.[ch].
228 * Changed the interface of silc_packet_assemble and the
229 silc_packet_send_prepare. If silc_packet_assmble is now
230 called the application does not call silc_packet_send_prepare
231 because the library will call it automatically. These
232 interfaces now also return a reference to the outgoing buffer
233 which includes the assembled packet, which the application can
234 use to encrypt the packet.
236 Affected files are lib/silccore/silcpacket.[ch],
237 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
238 silcd/packet_send.c, server_backup.c and packet_receive.c.
240 * Fixed a packet sending bug on very high load, where outgoing
241 packet queue wasn't handled correctly and packets got corrupted.
242 Affected files are lib/silcutil/*/silc*sockconn.c,
243 lib/silcclient/client.c and silcd/server.c.
245 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
247 * Added macro SILC_PACKET_DATALEN which can be used during
248 packet assembling to check whether the data to be added to
249 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
250 len is truncated until it fits it.
252 Added checks for maximum length of channel message payload and
253 private message payload also.
255 Added checks for maximum packet length in server and in
258 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
259 lib/silcclient/client.c, lib/silccore/silcchannel.c and
260 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
261 lib/silcclient/client_prvmsg.c.
263 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
265 * Added silc_server_packet_queue_purge call to the
266 silc_server_disconnect_remote to assure that all data in the
267 queue before disconnecting is sent to the network. Affected
270 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Added the deleting of server's own ID cache entry to the
273 silc_server_free function. Free also everything else that
274 has been allocated in silc_server_init. The affected file
277 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
279 * Added functions silc_parse_version_string, silc_version_to_num,
280 and silc_ske_parse_version to parse SILC protocol style version
281 strings. Affected files lib/silcutil/silcutil.[ch] and
282 lib/silcske/silcske.[ch].
284 * Added new configuration params: version_protocol, version_software
285 and version_software_vendor to specify what version the remote
286 host must at least be to be able to connect to server. The vendor
287 string can be regex matched too. Added new function
288 silc_server_connection_allowed to check maximum number of allowed
289 connections, and allowed versions for incoming connections.
290 Affected files are silcd/server.c, server_util.[ch] and
293 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
295 * Added preliminary support for signals in scheduler. The
296 signals we care about are now blocked always when the scheduler
297 is locked. This way we can synchronise the use of signal with
298 scheduler. It is guaranteed that when signal occurs the scheduler
299 is not locked, and thus new tasks can be safely added to the
302 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
303 to silc_schedule_internal_init and silc_schedule_internal_uninit.
304 Added new platform specific routines
305 silc_schedule_internal_signals_[un]block and
306 silc_schedule_internal_signal_[un]register.
308 Added new functions to SILC Schedule API:
309 silc_schedule_signal_[un]register. Each signal that application
310 is going to use should be registered to the scheduler.
312 Affected files are lib/silcutil/silcschedule.[ch],
313 lib/silcutil/*/silc*schedule.c.
315 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Check for unauthenticated client and server in the
318 silc_server_new_client and silc_server_new_server functions.
319 Affected file silcd/packet_receive.c.
321 * Added function silc_string_is_ascii to check whether given
322 string is 7-bit ASCII string. Affected files are
323 lib/silcutil/silcutil.[ch].
325 * Added function silc_id_is_valid_server_id into the
326 silcd/serverid.c and added checking for valid Server ID's in
327 silc_server_new_server. The Server ID must always be based
328 on the server's public IP address.
330 * Added logging of DISCONNECT packet message in the server.
331 Affected file silcd/server.c.
333 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
335 * Changed all library interfaces that use Global RNG to also
336 accept SilcRng as argument. Affected files are
337 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
338 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
339 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
340 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
343 * Added function silc_pkcs_generate_key to the
344 lib/silccrypt/silcpkcs.[ch] for applications so that they
345 don't need to do pkcs->pkcs->init calls anymore.
347 * Remove SilcSocketConnection from the SFTP API since it really
348 wasn't needed there. The application has the information
349 saved in its contexts anyway and the SFTP layer doesn't need
350 know about it. Affected files lib/silcsft/silcsftp.h and
351 lib/silcsftp/sftp_[server/client].c.
353 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
354 The SilcSimContext is not SilcSim.
356 * Fixed possible buffer overflows in silc_id_render in the
357 lib/silcutil/silcutil.c.
359 * On EPOC the global crypto module lists are not used at all
360 in the crypto library. Added support for using the constant
361 algorithm list on EPOC. Affected files are
362 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
365 * Fixed the handling of third parameter of KICKED notify, since
366 it was mistakenly updated to SILC Protocol 1.0 even though it
367 is to be included in 1.1. Since it is not in 1.0 it is not
368 mandatory, and this fix now handles it only if it is provided,
369 and it is not error if it is not provided. Affected file
370 lib/silcclient/client_notify.c.
372 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
374 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
375 client. Affected file irssi/src/silc/core/client_ops.c.
377 * Merged with Irssi 0.8.4 from irssi.org CVS.
379 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
381 * Check for valid socket connection in client entries before
382 sending any messages. Fixes a crash, but doesn't fix some
383 other underlaying bug that is lurking there. Affected
384 file silcd/packet_send.c.
386 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
388 * $usermode, $cumode and $cumode_space expandos shouldn't do
389 anything with non-SILC server records. Affected file
390 irssi/src/silc/core/silc-expandos.c
392 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
394 * Fixed the silc_net_check_[host/local]_by_sock to support
395 IPv6 bound sockets as well. Now they can return IPv6 addresses
396 as well. Affected file lib/silcutil/silcnet.c.
398 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
399 Affected lib/silcutil/unix/silcunixnet.c.
401 * Fixed ID rendering (at least on some platforms, not NetBSD)
402 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
404 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
406 * Added silc_hash_public_key and silc_hash_public_key_compare
407 functions to be used with SilcHashTable. They can be used to
408 hash public keys and compare public keys in hash table. Affected
409 file lib/silcutil/silcutil.[ch].
411 * Added support for specifying multiple public keys for Client
412 connection section in server configuration file. This makes it
413 possible to accept multiple public keys from same host, or to
414 make a section that accepts any incoming host, and have the
415 accepted public keys listed in the section.
417 Added functions silc_sever_[find/get]_public_key, added the
418 support for this actually to all connection sections but only
419 the Client section is currently allowed to specify multiple
422 Affected files are silcd/server.c, server_internal.h,
423 command.c, protocol.c, server_util.[ch], packet_receive.c.
425 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Merged Irssi 0.8.2 from irssi.org CVS.
429 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
431 * If silc_debug is TRUE, also output standard logging messages
432 to stderr with the debug output.
434 Made silc_log_reset_all() flushing all channels before returning.
435 Also fixed some documentation typos.
437 Affected files are lib/silcutil/silclog.[ch].
439 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
441 * Fixed the server to check correctly the amount of connections
442 from single host, by checking also the type of the connection.
443 Fixed also the comparison of number of connections and number
444 of allowed connections. Affected files are silcd/server.c,
447 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
449 * Fixed the USERS command reply to save the user's mode on the
450 channel as well. Fixed JOIN command reply to check whether a
451 client is on channel already and not join it twice. Affected
452 file lib/silcclient/command_reply.c.
454 * Added new file silc-expandos.c into irssi/silc/core/ to return
455 various stuff for various signal for the statusbar etc. updating.
456 Now Irssi SILC client prints channel user modes etc. on the
459 * The user mode (like server/router operator changes) is now shown
460 on the Irssi SILC client's statusbar. The affected files are
461 irssi/src/silc/core/client_ops.c, silc-expandos.c.
463 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
465 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
466 to SILC_SCHEDULE_[UN]LOCK macros.
468 * Added more error printing to logs in server code. Affected
469 files silcd/server.c and silcd/protocol.c.
471 * Fixed -S option parsing in Irssi SILC Client. Affected file
472 irssi/src/silc/core/silc-core.c.
474 * Added silc_buffer_alloc_size function. Affected file is
475 lib/silcutil/silcbuffer.h.
477 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
479 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
480 constants. Affected files in
481 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
484 * Changed the internal SFTP Memory FS table to const. Affected
485 file lib/silcsftp/sftp_fs_memory.c.
487 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
489 * Fixed the buffer formatting and unformatting routines to
490 check the size of 64 bits types with sizeof(). Affected
491 file is lib/silcutil/silcbuffmt.c.
493 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
495 * Removed 0.6.x backwards support.
497 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
499 * Changed all integer type names:
500 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
501 to avoid collisions with other libraries using same type names
504 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Added `prefer_ipv6' argument to the functions
507 silc_net_gethostbyname[_async]. If it is TRUE it will return
508 IPv6 address over IPv4. If FALSE IPv4 address is returned
509 even if IPv6 address was found. Affected files
510 lib/silcutil/silcnet.[ch].
512 * Added support silc_net_create_connection[_async] to fallback
513 to IPv4 address if IPv6 address could not be used (like if
514 it doesn't work on a specific system). Affected file in
515 lib/silcutil/unix/silcunixnet.c.
517 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * Added silc_schedule_reinit function to do the enlarging
520 of the max tasks handling capabilities of the scheduler.
521 Affected files lib/silcutil/silcschedule.[ch].
523 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
525 * Added automatic extern "C" { ... } for C++ compilers so the
526 application does not need to define them. Affected file
527 includes/silcincludes.h.
529 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
530 old name went against naming convention. Applications now
531 include "silcclient.h" instead of "clientlibincludes.h".
532 Removed includes/clientlibincludes.h, it is redundant now.
534 * Renamed includes/version.h to silcversion.h.
536 * Added really preliminary support for OS/2 into the util
537 library. Only thread & mutex API is implemented, others
538 are still to be implemented. Created the lib/silcutil/os2/
539 directory. Created also file includes/silcos2.h.
541 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

594 the SKE interface a bit.
596 * Fixed padding problem in PKCS#1. The padding was not actually
597 random since the random number generator was used incorrectly.
598 This security bug affects only when encrypting with PKCS#1, and
599 it is not currently used at all in SILC. SILC only use signing
600 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
602 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

668 * Added new configuration options and blocks:
669 keepalive_secs, reconnect_count, reconnect_interval,
670 reconnect_interval_max, reconnect_keep_trying and
671 require_reverser_lookup. Added ConnectionParam block, and
672 implemented the connection parameters when connecting as
673 initiator and when accepting connections as responder.

676 whether given configuration value has been given already.
678 Affected files silcd/serverconfig.[c], server.[c].
680 * Splitted the doc/example_silcd.conf.in. Separated the crypto
681 algorithm parts and created new file silcalgs.conf, that
682 is now included from the example_silcd.conf.in.
684 * Optimized the silc_server_connect_to_router_second to take
685 the connection configuration object from the SilcServerConnection
686 object instead of finding it during the connecting phase.
687 Added the configuration object to SilcServerConnection struct.
688 Affected files silcd/server_internal.h, server.c.

712 authentication to be set at the same time.
714 Added `prefer_passphrase_auth' setting in config file which
715 can be used to set to prefer passwd auth if both passwd and
716 public key is set. If not set, public key is preferred.
717 This has effect only when being initiator (responder will try
720 Added support for authentication with passphrase and public key
721 at the same time. The passphrase is tried first always since
722 it is faster to check.
724 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
726 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

768 hash algorithm. Affected file lib/silccrypt/silcrng.c.
770 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
772 * Fixed the file transfer's key agreement payload to include
773 zero port also if the hostname is NULL because it could not
776 Call file transfer monitor callback now also if error occurs
777 during key agreement protocol.
779 Changed the silc_client_file_send interface to return the
780 SilcClientFileError instead of session id. The session ID
781 is returned into pointer provided as argument.
783 Check that the file exists locally before sending the
784 file transfer request at all.
786 Affected file lib/silcclient/client_ftp.c, silcapi.h.

798 file lib/silcutil/silclog.c.
800 * Fixed the channel message payload decryption in the function
801 silc_channel_message_payload_decrypt to not modify the original
802 buffer before it is verified that the message decrypted
803 correctly. Otherwise, next time it is called with correct
804 channel key it won't encrypt since the payload is corrupted.
805 Affected file lib/silccore/silcchannel.c.
807 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

820 the table with foreach callback. The current entry may
821 become invalid in the callback but it was referenced after
822 the callback returned.
824 Do not allow auto rehashing of hash table during the
825 silc_hash_table_foreach operation, for same reasons as it is
826 not allowed for SilcHashTableList. Affected files are
827 lib/silcutil/silchashtable.[ch].
829 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Defined DLLAPI into silcincludes.h and silcwin32.h for

845 silc_client_new_channel_id and silc_idlist_get_channel_by_id
848 * Added cross reference of the joined channels to the
849 SilcClientEntry, and changed the SilcChannelEntry's
850 users list to SilcHashTable. The affected files are
851 lib/silcclient/idlist.[ch].
853 * Fixed a bug in hash table tarversing. While the hash table
854 is traversed with SilcHashTableList the table must not be
855 rehashed. It is now guaranteed that auto rehashable tables
856 are not rehashed while tarversing the list. Also defined that
857 silc_hash_table_rehash must not be called while tarversing
858 the table. Added function silc_hash_table_list_reset that must
859 be called after the tarversing is over. The affected files are
860 lib/silcutil/silchashtable.[ch].
862 * Changed all hash table traversing to call the new
863 silc_hash_table_list_reset in server and in client library.
865 * Added function silc_client_on_channel to return the
866 SilcChannelUser entry if the specified client entry is joined
867 on the specified channel. This is exported to application as
868 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

874 not only if !cmd->pending. Affected file silcd/command.c.
876 * Fixed the WHOWAS command's reply sending to support the
877 lists correctly. Affected file silcd/command.c.
879 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
881 * When sending JOIN command to router for processing the
882 sender's old command identifier was not saved back to the
883 sender's command context, fixed now. The affected file is
886 * Create the key in JOIN command of the router did not return
887 the channel key, added check for this. Affected file is
890 * Fixed a channel ID update bug in JOIN command reply. Do
891 not directly upgrade the ID but call the function
892 silc_idlist_replace_channel_id if the ID was changed.
893 Affected file silcd/command_reply.c.
895 * Fixed memory leaks from command calling if it would fail.
896 Affected file silcd/command.c.

908 * Removed TRQ from lib/trq, not needed anymore.
910 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
911 with server connections. Later this will be configurable
912 in config file after new config file is done. Affected file
915 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
917 * Fixed a crash in server related to channel announcements.
918 Affected file silcd/server.c.
920 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
922 * Fixed memory leaks in silc_server_create_new_channel*
923 functions. Affected file silcd/server.c.
925 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
926 which ID was changed. This way the router will send the
927 user list for the channel again, and server won't be in
928 desync in some rare circumstances. Affected file is
929 silcd/packet_receive.c.
931 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

960 file silcd/packet_receive.c and silcd/command.c.
962 * Fixed the SERVER_SIGNOFF notify handling on normal server
963 not to save the history information for clients. Same was
964 fixed earlier in remove_clients_by_server function, but not
965 here. Affected file silcd/packet_receive.c.
967 * Raised the default connection-retry count from 4 to 7 in
968 server. Affected file silcd/server.h.
970 * Cancel any possible reconnect timeouts when we start the
971 key exchange. Affected file silcd/server.c.

983 local entry will always get the unformatted nickname.
984 Affected file lib/silcclient/idlist.c.
986 * Fixed some double frees from client library commands.
987 Affected file is lib/silcclient/command.c.
989 * Fixed CUMODE command in server to assure that no one can
990 change founder's mode than the founder itself, there was a
991 little bug. Affected file silcd/command.c.
993 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
995 * Removed the SilcClientCommandDestructor from the client
996 libary, it is not needed anymore. Affected files are
997 lib/silcclient/silcapi.h, command[_reply].[ch],
998 client_notify, idlist.c.
1000 * Fixed GETKEY command to first resolve client, and then
1001 resolve the server only if the client was not found, instead
1002 of resolving both at the same time. Affected file is
1003 lib/silcclient/command.c.
1005 * Added silc_client_start_key_exchange_cb and lookup the
1006 remote hostname and IP address before starting the key
1007 exchange with server. The affected file is
1008 lib/silcclient/client.c.
1010 * The server's public key is now saved using the IP address
1011 of the server and not the servername for the filename.
1012 The hostname public key filename is checked as an fall back
1013 method if the IP address based filename is not found.
1015 Fixed the GETKEY command to save the fetched server key
1016 in correct filename.
1018 Print the remote server's hostname now when new key is
1019 received during connection process. Affected file is
1020 irssi/src/silc/core/client_ops.c.
1022 * Return always our own public key to the client if it asks
1023 for it with GETKEY command. Affected file silcd/command.c.
1025 * Removed the use_auto_addr variable from default config
1026 file since it was in wrong section. Affected file is
1029 * Fixed TOPIC_CHANGE notification to not route it when it
1030 was sent using silc_server_send_notify_to_channel function.
1031 Affected file silcd/command.c.
1033 * Fixed silc_server_send_notify_kicked to send the kicker's
1034 Client ID also, it was missing. Affected files are
1035 silcd/command.c, silcd/packet_send.[ch].
1037 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1039 * Do not save client history information in SERVER_SIGNOFF.
1040 Fixes the bug in normal server that it does not detect
1041 the client becoming valid after the server becomes back
1042 online. Affected file silcd/server_util.c.
1044 * Added `sock_error' field into the SilcSocketConnection
1045 context. When error occurs during socket operation (read
1046 or write) the error is saved. Added also new function
1047 silc_socket_get_error to return human readable socket error
1048 message. Affected files are lib/silcutil/silcsockconn.[ch],
1049 lib/silcutil/unix/silcunixsockconn.c, and
1050 lib/silcutil/win32/silcwin32sockconn.c.
1052 * The server now prints the socket error message in the
1053 signoff for client. Affected file silcd/server.c.
1055 * Fixed the `created' channel information sending from router
1056 to server in JOIN command. Checks now whether the channel
1057 really was created or not and set it according that.
1059 Fixed the JOIN command to use the client entry's current
1060 ID during the joining procedure instead of the one it sent
1061 in the command (it is checked though), since it can change
1062 between the packet processing and command processing, and
1063 would just case unnecessary pain in the client end. Affected
1064 file silcd/command.c.
1066 * Fixed a channel key payload sending to use correct channel
1067 ID when the server was forced to change the channel's ID by
1068 router. Router sent the key payload with the old Channel ID.
1069 Affected file silcd/packet_receive.c.
1071 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1074 was provided in the JOIN command's command reply. Affected
1075 file silcd/command_reply.c.
1077 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1079 * Fixed silc_mp_sizeinbase to return the value correctly with
1080 MPI. Affected file lib/silcmath/mp_mpi.c.

1083 and gracefully stop the server when SIGTERM or SIGINT signals
1084 are received. Affected file silcd/silcd.c.
1086 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1088 * Simple handling of TERM and HUP signals. Also added some log
1089 flushing call around. Affected file is
1092 * Fixed small bugs in silclog.c. Now buffering output will take
1093 effect after 10 seconds since startup: This will ensure that
1094 no important startup messages are lost. Also output redirection
1095 will preserve original format ([Date] [Type] message).
1096 Affected file is lib/silcutil/silclog.c.
1098 * Added two options to the config file, in the logging section:
1099 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1100 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1102 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1104 * Do not print the warning about log files not being initialized
1105 more than once to avoid excess logging. Affected file is
1106 lib/silcutil/silclog.c.
1108 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1109 the SIM copying in make install in Makefile.am.pre.
1111 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1113 * Rewritten silclog APIs. Globally interesting changes follows:
1114 silc_log_set_files() changed to silc_log_set_file().
1115 silc_log_set_callbacks() changed to silc_log_set_callback().
1116 ROBOdoc documented silclog header file.
1117 SilcLogCb now returns bool to wether inihibit the default
1118 handler or not (to keep the old behaviour return always TRUE).
1119 The new APIs should also fix the problem of the
1120 silcd_error.log file that was written in the current directory.
1123 Log files streams will remain opened after silc_log_set_file()
1124 call, means less CPU usage notably on high traffic servers.
1125 File streams are now full buffered, and flushed to the disk
1126 every 5 minutes, lesses HD activity and CPU usage.
1127 Messages can be redirected, allowing admins to configure
1128 one single logfile for all server messages.
1129 the silc_log_quick global variable to activate fast-logging.
1130 Affected files lib/silcutil/silclog.[ch]
1132 * Changed some code to conform new silclog APIs. Affected
1133 files are doc/example_silcd.conf.in, silcd/server.c
1134 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1137 * Fixed a memory leak that could occur in some situations.
1138 Affected file silcd/serverconfig.c.
1140 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1142 * Added the silc_client_del_client to remove the client from
1143 all channels as well. Affected file lib/silcclient/idlist.c.
1145 * Fixed the client library to correctly remove the client
1146 from all channels when the client entry is being destroyed.
1147 Affected file lib/silcclient/client_notify.c, command.c.
1149 * Added auto-nicking support to the client library. If the
1150 applicatio now sets client->nickname it will be sent to the
1151 server after connecting by the library. This way for example
1152 SILCNICK (or IRCNICK) environment variables will have effect
1153 and always change the nickname automatically to whatever
1154 it is wanted. Affected file lib/silcclient/client.[ch].
1156 * Renamed silc_server_command_bad_chars to the
1157 silc_server_name_bad_chars and moved it to the
1158 silcd/server_util.[ch]. Added also new function
1159 silc_server_name_modify_bad to return nickname that
1160 includes bad characters as new nickname without those
1161 bad characters. This check and modify is now used in
1162 silc_server_new_client when the username is initially set
1163 as nickname, so it must be checked to be valid nickname.
1164 Affected file silcd/packet_receive.c.
1166 * The nickname length is now taken from the packet for real
1167 and not trusted to strlen() since it clearly can return
1168 wrong length for nickname including bad characters. This
1169 also applies to channel names. Affected file silcd/command.c.
1171 * Removed the lib/silcsilm/modules directory. Modules are now
1172 compiled into the lib/silcsim. Fixed the copying of the
1173 modules to follow symbolic links in Makefile.am.pre.
1175 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1177 * Fixed silc_string_regexify list creation. Fixes bugs with
1178 BAN and INVITE commands in server. The affected file is
1179 lib/silcutil/unix/silcunixutil.c.
1181 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1183 * Removed the command destructor entirely from the server's
1184 command and command reply routines. It is not needed, and
1185 its usage was buggy and caused crashes. Affected files are
1186 silcd/command[_reply].[ch].
1188 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Cancel protocol and NULL sock->protocol if timeout
1191 occurred during protocol. Affected file silcd/server.c.
1193 * Cancel protocol timeouts always before calling the final
1194 callback, to assure that after final callback is called
1195 no other state will be called for the protocol anymore.
1196 Affected file silcd/protocol.c.
1198 * Print error log if incoming connection configuration could
1199 not be found. Affected file silcd/server.c.
1201 * Fixed JOIN command to correctly save the founder mode
1202 to the client on normal SILC server, when the channel
1203 was created by the router. Affected file silcd/command.c.
1205 * Fixed LIST command (hopefully) to send correct reply
1206 packets. Affected file silcd/command.c.
1208 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * The silc_packet_receive_process now returns FALSE if the
1211 read data was invalid packet, and TRUE if it was ok.
1213 The server now checks that if unauthenticated connection
1214 sends data and its processing fails the server will close
1215 the connection since it could be a malicious flooder.
1217 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1219 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * Make sure the warning about error opening a log file is
1222 printed only once and not everytime it fails (produces
1223 too much useless log). Affected file lib/silcutil/silclog.c.
1225 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1227 * Made the silc_server_daemonise() function more readable.
1228 Affected file silcd/server.c.
1230 * Pid file is now optional, the user may comment it out from
1231 the config file. Removed define SILC_SERVER_PID_FILE, we
1232 don't need a default any longer. Affected file
1233 configure.in.pre, lib/Makefile.am.pre.
1235 * Make some use of the pid file. The server now dies at startup
1236 if it detects a valid pid file on his path. The server would
1237 die anyway in this circumstance, because of the bind() failure.
1238 Affected file silcd/silcd.c.
1240 * No longer compiling lib/dotconf.
1242 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Fixed JOIN command parsing not to crash. Affected file
1245 lib/silcclient/command.c.
1247 * Fied the NICK_CHANGE notify to add the new client entry
1248 even it is resolved. This removes an <[unknown]> nick
1249 thingy bug in the client. Affected file is
1250 lib/silcclient/client_notify.c.
1252 * Do not try to allocate 0 bytes (efence does not like it)
1253 in lib/silccore/silccomand.c when encoding payload.
1255 * Do not take IRCNICK as nickname in Irssi SILC client since
1256 it is not possible to set nickname before hand connecting
1257 the server (TODO has an entry about adding auto-nicking
1260 * Changed the silc_server_command_pending to check whether
1261 there already exists an pending entry with the specified
1262 command, command identifier and pending callback. This is
1263 to fix IDENTIFY and WHOIS related crashes that may register
1264 multiple pending commands with same identifier. Affected
1265 file silcd/command.c.
1267 * Fixed the server to reconnect to the router even if it
1268 was already reconnecting and EOF was received. This to
1269 fix a possibility that the server wouldn't ever try to
1270 auto-reconnect to the router. Affected file silcd/server.c.
1272 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1274 * Fixed the server's password authentication to use the
1275 length of the locally saved password, and not the one
1276 sent in the packet. Affected file silcd/protocol.c.
1278 * Fixed same password authentication problem in the
1279 Authentication Payload handling routines in
1280 lib/silccore/silcauth.c.
1282 * Yet another password authentication problem fixed with
1283 channel password handling in silcd/command.c.
1285 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * If first character of string in silc_parse_userfqdn is '@'
1288 then do not parse it. Affected file is
1289 lib/silcutil/silcutil.c.
1291 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Fixed minor bug in IDENTIFY command reply sending, which
1294 caused various weird problems during JOIN when it was
1295 resolving names for users. Affected file silcd/command.c.
1297 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1299 * Fixed the IDENTIFY command reply sending to chech better valid
1300 clients. It was possible to send incomplete list of replies.
1301 Affected file silcd/command.c.
1303 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1305 * Added silc_client_command[s]_[un]register functions now to
1306 dynamically register the commands in client library. Removed
1307 the static table of commands. This allows the client library
1308 to call commands without causing the application to know about
1309 what commands library has called.
1311 Removed the INFO command reply kludge to detect when the command
1312 was called by library. Now library use its own command reply
1313 function for INFO command.
1315 Added function silc_client_command_call to call a command.
1316 Application can use it to call command, not access the structure
1319 Now all commands that are sent by the client library (not
1320 explicitly sent by application) use own command reply functions.
1322 Affected files around lib/silcclient/ and in
1323 irssi/src/silc/core/.
1325 * Fixed the WHOIS command reply sending to chech better valid
1326 clients. It was possible to send incomplete list of replies.
1328 Fixed the WHOIS and IDENTIFY to send the request to router
1329 if normal server did not do it and did not find any results.
1331 Affected file silcd/command.c.
1333 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Moved the internal data from SilcClient context into its
1336 own file, not accesible to application. Affected files
1337 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1338 and other files in client library.
1340 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Added doc/examples installation target in Makefile.am.pre.
1345 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1348 commands the found client entry will be removed from the
1349 cache, after notifying application about the error. Affected
1350 file lib/silcclient/command_reply.c.
1352 * Changed the /MSG to check for exact nickname user gave, and
1353 not let `nick' match `nick@host' if it is only one found. Now,
1354 user must type the exact nickname (like nick@host2) even if
1355 there are no more than one same nicks found. This is to avoid
1356 a possibility of sending nickname to wrong nickname since
1357 `nick' could match `nick@host'. Affected file is
1358 irssi/src/core/silc-servers.c.
1360 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Do not print "you are now server operator" or similar when
1363 giving /away command. Affected files are
1364 irssi/src/silc/core/client_ops.c, silc-servers.h.
1366 * Made the silc_server_command_pending_error_check to send
1367 the same command reply payload it received back to the
1368 original sender of the command. This way all arguments
1369 that was received by the server will be received by the
1370 client too. Affected file silcd/command.c.
1372 * Added the silc_idcache_add to return the created cache entry
1373 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1375 * Add global clients to expire if they are not on any channel.
1376 This is because normal server will never know if they signoff
1377 if they are not on any channel. The cache expiry will take
1378 case of these entries. This is done by normal servers only.
1379 The affected files are silcd/command_reply.c,
1380 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1382 * If server receives invalid ID notification for WHOIS or
1383 IDENTIFY and the ID exists in the lists, it is removed.
1384 Affected file silcd/command_reply.c.
1386 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1387 in client then client entry that it matches is searched and
1388 the nickname is printed on the screen for user. Affected
1389 file irssi/src/silc/core/client_ops.c.
1391 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Use cache entry expire time in the LIST command reply to
1394 purge old entries from the cache after the LIST command
1395 reply has been received. This way we don't have non-existent
1396 entries in the cache for too long. Affected file is
1397 silcd/command_reply.c.
1399 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * If we are normal server, and we've not resolved client info
1402 in WHOIS or IDENTIFY from router, and it is global client,
1403 we'll check whether it is on some channel. If it is not
1404 then we cannot be sure about its validity and will resolve it
1405 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1406 file silcd/command.c.
1408 * Search channel by name (if possible) rather than by ID
1409 in IDENTIFY command's command reply. Affected file is
1410 silcd/command_reply.c.
1412 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1415 Updated specs and implemented it. Affected file silcd/command.c,
1416 silcd/packet_send.c and silcd/packet_receive.c.
1418 * Implemented the <founder auth> payload handling in the JOIN
1419 command. If provided all conditions for channel joining
1420 except requirement to provide correct passphrase can be
1421 overrided by the channel founder. Updated the protocol specs.
1422 Affected file silcd/command.c.
1424 Added support for founder auth in JOIN command in client
1425 library. Fixed the parsing of the JOIN command now to support
1426 all options as they should be. The affected file is
1427 lib/silcclient/command.c.
1429 * Optimized the WHOIS and IDENTIFY commands to send the request
1430 to router only if it includes nicknames or other names. If
1431 they include only IDs then check the local cache first before
1432 routing. Affected file is silcd/command.c.
1434 * Added channels topic announcements. Affected file is
1435 silcd/packet_receive.c and silcd/server.c.
1437 * Fixed the silc_server_send_notify_topic_set to really destine
1438 the packet to channel. Affected file silcd/packet_send.c.
1440 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1441 library. Affected file lib/silcclient/client_notify.c.
1443 * Added UMODE announcements. Affected file silcd/server.c.
1445 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Memory leak fixes in:
1449 lib/silcutil/silcsockconn.c
1450 lib/silcske/silcske.c
1451 lib/silcske/groups.c
1453 lib/silccrypt/silcpkcs.c
1454 lib/silccore/silccommand.c
1455 lib/silccore/silcidcache.c
1460 * ROBOdoc documented the lib/silcske/groups.h file and a
1461 bit changed the interface for better.
1463 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1465 * Update the client entry context in the ID cache after
1466 nick change. Affected file lib/silcclient/command.c.
1467 Fixes the CUMODE command when regaining founder privileges,
1468 and a little WHOIS problem.
1470 * Fixed silc_net_gethostbyname to correctly call the
1471 inet_ntop. Affected file lib/silcutil/silcnet.c.
1473 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1475 * Added IPv6 support checking to the configure.in.pre, added
1476 also --enable-ipv6 option to override the check. Affected
1477 file configure.in.pre.
1479 * The silc_thread_create now calls the start function
1480 directly if threads support is not compiled in. Removes
1481 ugly #ifdef's from generic code. Affected files are
1482 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1484 * Added silc_net_gethostby[name/addr]_async to asynchronously
1485 resolve. Affected files are lib/silcutil/silcnet.[ch].
1487 * Added support for rendering IPv6 based server, client and
1488 channel IDs. Affected file lib/silcutil/silcutil.c.
1490 * Added support for creating IPv6 based server IDs. Affected
1491 file is silcd/serverid.c.
1493 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1495 * Added silc_net_gethostby[addr/name] into the
1496 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1497 routines. Added silc_net_is_ip[4/6]. Affected file is
1498 lib/silcutil/unix/silcunixnet.c. All routines that take
1499 address as argument now supports both IPv4 and IPv6 addresses.
1501 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1503 * Fixed LIST command reply sending in server. Affected file
1506 * Server now sends the kicker's client ID in the KICK notify
1507 to the kicked client. Affected file silcd/command.c.
1509 * The client library now parses the kickers client ID and
1510 UI displays it. Affected files lib/silcclient/client_notify.c
1511 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1513 * Made all payload parsing function prototypes consistent.
1514 They all take now const unsigned char * and uint32 pair as
1515 the payload data instead of SilcBuffer. Changes all around
1516 the source tree. Other unsigned char* -> const unsigned char*
1517 changes around the tree as well.
1519 * Optimized SFTP client and server packet sending not to
1520 allocate new buffer for each packet but to recycle the
1521 first allocated buffer. Affected files are
1522 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1524 * Optimized the SFTP client to use SilcList instead of
1525 SilcDList for requests, because it is faster. Affected file
1526 is lib/silcsftp/sftp_client.c.
1528 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1529 into lib/silccore/silcid.[ch].
1531 Renamed silcpayload.[ch] into silcargument.[ch].
1533 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1535 * If client entry is deleted with active key agreement
1536 session, abort the session.
1538 The silc_client_abort_key_agreement now calls the completion
1539 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1541 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1544 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1546 * Don't use __restrict in older GCC's. Affected file is
1547 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1549 * silc_net_localhost now attempts to reverse lookup the
1550 IP/hostname. Affected file lib/silcutil/silcnet.c.
1552 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1553 command. It can be used to gain founder privileges at
1554 the same time when joining the channel.
1556 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1557 kicker's client ID as well. Updated protocol specs.
1559 Defined that the server must send SILC_COMMAND_IDENTIFY
1560 command reply with error status to client who sent
1561 private message with invalid client ID.
1563 Updated the protocol specification.
1565 * Added silc_server_send_command_reply to send any
1566 command reply. Affected file silcd/packet_send.[ch].
1568 * Added silc_id_payload_encode_data to encode ID payload
1569 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1571 * The server now send IDENTIFY command reply with error
1572 status if client ID in private message is invalid. Affected
1573 file silcd/packet_receive.c.
1575 * Save the server key file with server's IP address in
1576 the filename instead of hostname. The affected file is
1577 irssi/src/silc/core/client_ops.c.
1579 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1584 * Added libtool support for compiling shared objects in
1585 lib/silcsim. Affected file configure.in.pre and
1586 lib/silcsim/Makefile.am. Original patch by cras.
1588 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1590 * Pid file configuration, and server's config file fixes
1591 patch by toma. Updated CREDITS file.
1593 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Fixed silc_client_channel_message to not try to decrypt
1596 the message twice if it resolved the destination client
1597 information. This could cause of dropping one channel
1598 message. Affected file lib/silcclient/client_channel.c.
1600 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1603 lib/silcclient/client.c. This function is used when the SILC
1604 Client is run under some other scheduler, or event loop or
1605 main loop. On GUI applications, for example this may be
1606 desired to used to run the client under the GUI application's
1607 main loop. Typically the GUI application would register an
1608 idle task that calls this function multiple times in a second
1609 to quickly process the SILC specific data.
1611 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1613 * Fixed silc_server_drop() for dropping the supplementary
1614 groups as well, this could cause a security hole on some
1617 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1622 * Write PID file after dropping privileges. Added -F option
1623 to run server on foreground. A patch by debolaz.
1624 Affected files silcd/server.c, silcd/silcd.c.
1626 * Fixed MOTD to return the MOTD file server name. Affected
1627 file silcd/command.c.
1629 * Added INFO command reply handling to the Irssi SILC Client.
1630 Affected file irssi/src/silc/core/client_ops.c.
1632 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * Fixed the silc_idcache_list_* routines to really support
1635 the dynamic list. Fixes a crash. Affected file is
1636 lib/silccore/silcidcache.c.
1638 * Fixed the LIST command reply to really call LIST command's
1639 pending callbacks. Affected file silcd/command_reply.c.
1641 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * Update conn->local_entry->nickname after giving NICK
1644 command. Affected file lib/silcclient/command.c.
1646 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1648 * Added the [pid] option to the silcd configuration file
1650 Affected files: serverconfig.[ch] and silcd.c
1652 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Save fingerprint in WHOIS command reply in server.
1655 Affected file silcd/command_reply.c.
1657 * Fixed NICK commands pending callback registration.
1658 Affected file lib/silcclient/command.c.
1660 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Use ++server->cmd_ident when sending commands in server,
1663 instead of random number. Affected file silcd/command.c.
1665 * Fixed GETKEY command reply to call actually GETKEY pending
1666 command callbacks. Affected file silcd/command_reply.c.
1668 * A bit stricter check for nicknames. Check for same nickname
1669 in NICK command also. Affected file silcd/command.c.
1671 * Do not call INFO command everytime client ID changes, only
1672 during first connecting. Affected file lib/silcclient/client.c.
1674 * Set the new nickname only after successful command reply for
1675 NICK command is returned by server. Affected file
1676 lib/silcclient/command.c.
1678 * Remove nicknames from nicklist during server_signoff notify.
1679 Should fix /NAMES bit more. The affected file is
1680 irssi/src/silc/core/silc-channels.c.
1682 * Added `fingerprint' field to the SilcIDListData in the
1683 silcd/idlist.h to hold the fingerprint of the client's
1686 Send the fingerprint of the client's public key in WHOIS
1689 Affected files silcd/command.c, and silcd/idlist.[ch].
1691 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1692 create fingerprint from given data.
1694 * Show the fingerprint of the client's public key in WHOIS.
1695 Affected files irssi/src/module-formats.[ch] and
1696 irssi/src/silc/core/client_ops.c.
1698 * Format the multiple same nicknames also during JOIN and
1699 NICK_CHANGE notifys. Affected file is
1700 lib/silcclient/client_notify.c.
1702 * Do not print error on screen for invalid private message
1703 payload since it can come if someone is sending private
1704 messages with wrong key. Affected file
1705 lib/silccore/silcprivate.c.
1707 * Fixed multiple concurrent /PING crash. Affected file
1708 lib/silcclient/command.c.
1710 * Changed the wrong ID encoding. All IP addresses must be
1711 in MSB first order in encoded format. They were encoded
1712 wrong and was in LSB format. Affected files are
1713 silcd/serverid.c, lib/silcutil/silcutil.c.
1715 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1717 * Call the `connect' client operation through the scheduler
1718 in case of error. Affected file lib/silcclient/client.c.
1720 * Call the `failure' client operation even if the error
1721 occurred locally during a protocol. Affected file is
1722 lib/silcclient/protocol.c.
1724 * Added support of sending LIST command to router from normal
1725 server. This way normal server can get list of all channels
1726 in the network too. Fixed the channel list sending in the
1727 server too. Affected files are silcd/command.c, and
1728 silcd/command_reply.[ch].
1730 * Added silc_server_update_channels_by_server and
1731 silc_server_remove_channels_by_server. They are used during
1732 disconnection of primary router and in backup router protocol.
1733 Affected file silcd/server_util.[ch], silcd/server.c and
1734 silcd/server_backup.c.
1736 * Fixed channel adding to global list in IDENTIFY command
1737 reply in server. Affected file silcd/command_reply.c.
1739 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * If the incoming packet type is REKEY or REKEY_DONE process
1742 that packet always synchronously. Fixes yet another MAC
1743 failed error on slow (dialup) connections. Affected file
1744 lib/silcclient/client.c and silcd/server.c.
1746 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Call check_version SKE callback for initiator too. Affected
1749 file lib/silcske/silcske.c.
1751 * Implemented fix for security hole found in the SKE that was
1752 fixed in the specification few days back; the initiator's
1753 public key is now added to the HASH value computation.
1754 Added backwards support for the old way of doing it too, for
1755 old clients and old servers. Affected file is
1756 lib/silcske/silcske.c.
1758 * Enabled mutual authentication by default in SKE. If initiator
1759 is not providing mutual authentication the responder will
1760 force it. This will provide the proof of posession of the
1761 private key for responder. The affected files are
1762 lib/silcclient/protocol.c and silcd/protocol.c.
1764 * Do not cache anymore the server's public key during SKE.
1765 We do mutual authentication so the proof of posession of
1766 private key is done, and if the server is authenticated in
1767 conn auth protocol with public key we must have the public
1768 key already. Affected file silcd/protocol.c.
1770 * Added new global debug variable: silc_debug_hexdump. If
1771 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1772 file lib/silcutil/silclog.[ch].
1774 * Fixed compilation warning due to char * -> const char *.
1775 Affected files lib/silcutil/silcnet.h, and
1776 lib/silccore/silcauth.[ch].
1778 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Fixed CMODE command when new channel key was created. If
1781 the creation failed the old key was removed. Next time giving
1782 same command would crash the server since the old key was
1783 freed already. Affected file silcd/command.c.
1785 * Fixed the silc_server_announce_get_channels to not crash
1786 on reconnect. Affected file silcd/server.c.
1788 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Added silc_log_set_debug_string function to set a regex
1791 string to match for debug output. Only the function names,
1792 or filenames matching the given debug string is actually
1793 printed. This way it is possible to filter out those debug
1794 strings that user is not interested in.
1796 Fixed a bug in silc_string_regexify.
1798 Affected files lib/silcutil/silclog.[ch], and
1799 lib/silcutil/unix/silcunixutil.c.
1801 * Changed the -d options in both server and Irssi SILC client
1802 to take the debug string as argument. Affected files
1803 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1805 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Added silc_hash_babbleprint to create a Bubble Babble
1808 Encoded fingerprint. The encoding is developed by Antti
1809 Huima (draft-huima-babble-01.txt), and it creates human
1810 readable strings out of binary data. Affected file
1811 lib/silccrypt/silchash.[ch].
1813 * Print the babble print now in addition of fingerprint as well
1814 in Irssi SILC client. Affected files are
1815 irssi/src/fe-common/silc/module-formats.[ch],
1816 irssi/src/fe-common/silc/core/client_ops.c.
1818 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Fixed a security problem found in SKE. The initiator's
1821 public key too is now added to the HASH hash value creation
1822 which is signed by the responder to create the SIGN value.
1823 This will prevent anyone in the middle to lie to the responder
1824 about the initiator's public key. If this is done now, the
1825 man in the middle will get caught. Updated the protocol
1828 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * Better installation directory handling. Configure module
1831 paths and other paths automatically to example_silc* files
1832 in doc/. A patch by toma.
1834 * Fixed compiler warning from MPI library, and from SILC RNG.
1837 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1838 It can be configured with ./configure. A patch by toma.
1840 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Find correct make to use in prepare-clean. A patch by
1843 toma. Affected file prepare-clean.
1845 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1847 * Added irssi variables use_auto_addr, auto_bind_ip,
1848 auto_bind_port and auto_public_ip.
1850 * Changed the interface for silc_client_send_key_agreement
1851 in lib/silcclient/silcapi.h
1855 irssi/src/silc/core/silc-core.c
1857 lib/silcclient/silcapi.h
1858 irssi/src/silc/core/silc-channels.c
1859 lib/silcclient/client_keyagr.c
1862 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Added silc_pkcs_public_key_compare to compare two
1865 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1867 * Check that the client who set the founder mode on the
1868 channel is the same client that is giving the founder
1869 mode to itself. It is done by comparing the saved public
1870 key (it is saved even in the authentication is passphrase).
1871 Affected file silcd/command.c.
1873 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Do not process packet for disconnected socket connection.
1876 Affected file lib/silccore/silcpacket.c.
1878 * Process the DISCONNECT packet through scheduler in the
1879 client library. Affected file lib/silcclient/client.c.
1881 * Fixed the silc_client_packet_parse to not to increase
1882 the packet sequence number if the conn->sock and the
1883 current socket connection is not same. This can happen
1884 for example during key agreement when the conn includes
1885 multiple socket connections (listeners). Affected file
1886 lib/silcclient/client.c.
1888 * The sender of the file transfer request now provides also
1889 the pointer (listener) for the key exchange protocol. If
1890 the listener cannot be created then it sends empty key
1891 agreement and lets the receiver provide the listener.
1893 Added `local_ip' and `local_port' arguments to the
1894 silc_client_file_send. If they are provided they are used,
1895 if not then it will attempt to find local IP address, if
1896 not found or bind fails then the remote client will provide
1899 Affected files are lib/silcclient/client_ftp.c and
1900 lib/silcclient/silcapi.h.
1902 * Extended the FILE SEND command to support defining the
1903 local IP and port for key exchange listener. They are
1904 optional. Affected file irssi/src/silc/core/silc-servers.c.
1906 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * Defined to WHOIS command reply the sending of fingerprint
1909 of the client's public key (if the proof of posession of the
1910 corresponding private key is verified by the server).
1911 Updated to the protocol specification.
1913 * Added support of receiving the client's public key's
1914 fingerprint in command reply in client library. Affected
1915 file is lib/silcclient/command_reply.c, and
1916 lib/silcclient/idlist.[ch].
1918 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1920 * Do not send over 128 chars long nickname to the server
1921 in NICK command. Affected file lib/silcclient/command.c.
1923 * Do not send over 256 chars long channel names to the server
1924 in JOIN command. Affected file lib/silcclient/command.c.
1926 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Assure that silc_server_close_connection cannot be called
1929 twice for same socket context. Affected file is
1932 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Send error message to application if opening file for
1935 writing during file transfer fails. Affected file is
1936 lib/silcclient/client_ftp.c.
1938 Remove all file transfer sessions for a client that we're
1939 removing from ID cache.
1941 Affected file is lib/silcclient/client_ftp.c.
1943 * Fixed silc_net_addr2bin to return correct address. Affected
1944 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1946 * Fixed file transfer session removing on signoff notify.
1947 Affected file irssi/src/silc/core/silc-servers.c.
1949 * Added the SilcClientFileError to be returned in the monitor
1950 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1951 Affected file lib/silcclient/silcapi.h.
1953 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Fixed a crash in silc_client_ftp_free_sessions and
1956 silc_client_ftp_session_free_client. Affected file
1957 lib/silcclient/client_ftp.c.
1959 * Added `disabled' field in the SilcChannelEntry in the server
1960 to indicate if the server entry is disabled. Affected file
1961 silcd/idlist.h, silcd/command[_reply].c.

1970 * Fixed a crash in client resolving in client_prvmsg.c in
1971 client library. Affected file lib/silcclient/client_prvmsg.c.
1973 * Do not actually remove the client directly from ID cache
1974 during SERVER_SIGNOFF, but invalidate it. This way we
1975 preserve the WHOWAS info for the client. Affected file
1976 silcd/server_util.c.
1978 * Fixed SERVER_SIGNOFF notify handling in the server. The
1979 server is now able to process incoming SERVER_SIGNOFF notify
1980 for a server that it doesn't even know about. It will remove
1981 the clients provided in the notify. Affected file
1982 silcd/packet_receive.c.
1984 * Check for partial packet in data queue after every packet that
1985 was found from the queue. Return and wait for more data if
1986 there is partial data in queue. Affected file is
1987 lib/silccore/silcpacket.c.

2008 * Added silc_rng_global_get_byte_fast to get not-so-secure
2009 random data as fast as possible. Random data is read from
2010 /dev/urandom if available and from the SILC RNG if not
2011 available. It is used in padding generation. Affected file
2012 lib/silccrypt/silcrng.[ch].
2014 * All packets in client library are now processed synchronously.
2015 Optimized packet processing a lot. Affected file
2016 lib/silcclient/client.c.
2018 * All server connection packets are processing synchronously
2019 now in server, to optimize packet processing. Affected file
2022 * Include files are installed now only in Toolkit distribution
2023 if make install is given. Affected files: all Makefile.am's.

2029 be found by the first it cannot be found at all. Affected
2030 file lib/silcclient/client_notify.c.
2032 * Fixed WHOWAS command reply calling. Affected file
2033 lib/silcclient/command_reply.c.
2035 * Removed all references to silc_idlist_get_client from the
2036 Irssi SILC client since that call is internal call used by
2037 the library. The Irssi SILC client will use now client
2038 retrieval functions found in silcapi.h.
2040 * Fixed a bug in resolving nickname info before sending
2041 private message. It used freed memory. Affected file
2042 irssi/src/silc/core/silc-servers.c.
2044 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2063 * Added silc_net_localip to return local host's IP address.
2064 Affected file lib/silcutil/silcnet.[ch].
2066 * If key exchange or rekey protocol is active for a connection
2067 parse all packets syncronously since there might be packets
2068 in packet queue that we are not able to process without first
2069 processing packets before them. Affected file silcd/server,
2070 lib/silcclient/client.c.
2072 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2073 whether library should continue processing the packet.
2074 Affected file lib/silccore/silcpacket.h.

2143 Affected file silcd/command.c.
2145 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2147 * Call the silc_server_udpate_servers_by_server in the
2148 primary router that comes back online in the backup resuming
2149 protocol. Otherwise it routes packets wrong. Affected file
2150 silcd/server_util.[ch], silcd/server_backup.c.
2152 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2155 lib/silcutil/silcbuffmt.[ch].
2157 * Redefined the SILC packet header to include the padding
2158 length. Affected file lib/silccore/silcpacket.[ch].
2160 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2161 length for maximum padding up to 128 bytes). Affected
2162 file lib/silccore/silcpacket.h.
2164 * Removed all backwards support for old 0.5.x MAC thingies.
2165 The SILC packet header change makes it impossible to be
2166 backwards compatible.
2168 * Send the ENDING packet with timeout in the backup resuming
2169 protocol. This is to assure that all routers has connected
2170 to the primary router. Affected file silcd/server_backup.c.
2172 * Changed the RNG to take the first IV from random data. It
2173 used to take it from zero actually. Changed the RNG also
2174 to use /dev/urandom during session. /dev/random is used
2175 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2177 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Changed the SILC packet header to have the first two bytes
2180 (the packet length) encrypted. Affected files aroung the
2181 code tree, lib/silccore/silcpacket.[ch]. Removed the
2182 SilcPacketCheckDecrypt callback. It is not needed anymore
2183 since the silc_packet_receive_process will determine now
2184 whether the packet is normal or special.
2186 * Implemented the unidirectional MAC keys. Affected files
2187 lib/silcske/silcske.c, silcd/protocol.c and
2188 lib/silcclient/protocol.c.
2190 * Implemented the packet sequence number to the MAC computation.
2191 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2192 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2193 lib/silcclient/protocol.c.
2195 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * Allow backup router to announce servers. All servers
2198 announced by backup router are added to the global list
2199 automatically. Update hte server's socket to our primary
2200 router also when backup router announces a server.
2201 Affected file silcd/packet_receive.c.
2203 * Do not update the client->router in the function
2204 silc_server_udpate_clients_by_server if the client is on
2205 global list. We might fail to find any specific server
2206 for locally connected clients and local cell clients. They
2207 should still use the `from' and not `to' as client->router.
2208 This fixes backup router resuming protocol. Affected file
2209 silcd/server_util.c.
2211 * Decrease channel statistics count only if the channel
2212 deletion worked. Affected files are silcd/server.c and
2213 silcd/server_util.c.
2215 * Added silc_server_update_servers_by_server to update origin
2216 of all server entries. Used during backup router protocol.
2217 Affected files silcd/server_util.[ch], silcd/server.c. and
2218 silcd/backup_router.c.
2220 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2221 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2222 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2223 lib/silccrypt/silchmac.c.
2225 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Assure that router cannot reroute the same channel message
2228 to the sender. Affected file silcd/packet_receive.c.
2230 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2232 * Made better checks that the channel message is not sent
2233 to the router it came from. Affected file is
2234 silcd/packet_send.c. Fixed memory leak too.
2236 * Announce informations for incoming router connection, but
2237 only after checking if it is replaced by backup router.
2238 Affected file silcd/packet_receive.c.
2240 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Fixed the backup resuming protocol to work in multiple
2243 router environment. Affected file silcd/server_backup.c.
2245 * Route packet only to one router in the function
2246 silc_server_packet_send_to_channel. Affected file is
2247 silcd/packet_send.c.
2249 * Fixed silc_server_send_notify_dest to set the broadcast
2250 flag. Fixed the silc_server_send_notify_topic to actually
2251 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2252 Affected file silcd/packet_send.c.
2254 * Changed the SFTP Filesystem interface. Changed the
2255 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2256 the filesystem operation function. The SilcSFTPFilesystem
2257 is now a context that is allocated by all filesystem allocation
2258 functions and it already includes the operations structure
2259 and filesystem specific context. It is given as argument
2260 now to the silc_sftp_server_start. This made the interface
2261 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2262 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2264 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Changed the backup router adding and getting interfaces
2267 in the server. The router that will be replaced by the
2268 specified backup router is now sent as argument. Affected
2269 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2272 * Added silc_net_addr2bin_ne to return the binary form of
2273 the IP address in network byte order. Affected files
2274 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2276 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Check for existing server ID in silc_server_new_server
2279 and in silc_server_connect_to_router_final and remove the
2280 old entry if it exists. Affected file silcd/packet_receive.c,
2283 * Send the channel message always to only one router, either
2284 in upstream or downstream. Affected file is
2285 silcd/packet_send.c.
2287 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Wrote the definition of the backup resuming protocol to the
2290 protocol specification.
2292 * Removed one redundant channel key generation from normal
2293 server during joining procedure. Removed one redundant
2294 channel key sending from server to router during joining
2295 procedure. Affected file silcd/command.c.
2297 * Made minor bugfixes to the backup router resuming protocol.
2298 Affected file silcd/server_backup.c, server.c.
2300 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * Added --disable-asm configuration option. Affected files
2303 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2306 * Implemented the backup resuming protocol that is used to
2307 resume the primary router position in the cell after the
2308 primary router comes back online. Affected files
2309 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2310 and silcd/server_util.[ch].
2312 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Sleep two (2) seconds after sending QUIT command to server.
2315 Affected file lib/silcclient/command.c.
2317 * Assure that if outgoing data buffer is pending do not force
2318 send any data. Affected file silcd/packet_send.c.
2320 * Assure that if outgoing data buffer is pending do not force
2321 send any data. Affected file lib/silcclient/client.c.
2323 * Implemented the backup router support when the primary router
2324 goes down. The servers and routers can now use the backup
2325 router as new primary router without loosing connectivity.
2327 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2330 in the server to indicate disabled entry. All data read
2331 from the connection will be ignored and no data is sent
2332 for entry that is disabled. Affected files are
2333 silcd/idlist.h, silcd/server.c.
2335 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2337 * Created SFTP client and server test programs in the
2338 lib/silcsftp/tests directory.
2340 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Implemented memory filesystem (virtual filesystem) for
2343 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2346 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Implemented the SFTP (SSH File Transfer Protocol) to the
2349 lib/silcsftp. It includes SFTP client and SFTP server
2352 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Moved lib/silccore/silcprotocol.[ch] to the
2355 lib/silcutil library.
2357 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2358 take variable argument list pointer as argument. Affected
2359 file lib/silcutil/silcbuffmt.[ch].
2361 * Added silc_buffer_set function that is used to set data
2362 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2363 Affected file lib/silcutil/silcbuffer.h.
2365 * Changed various routines in the core library to use the new
2366 silc_buffer_set instead of allocating new buffer only for
2369 * Added 64-bit value formatting and unformatting support to the
2370 silc_buffer_[un]format routines. Affected file is
2371 lib/silcutil/silcbuffmt.[ch].
2373 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2374 to includes/bitmove.h.
2376 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Fixed channel user mode saving in client library. Affected
2379 file lib/silcclient/command[_reply].c.
2381 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Defined the file transfer to the SILC Protocol. Added
2384 new packet type SILC_PACKET_FTP and defined File Transfer
2385 Payload. The mandatory file transfer protocol is SFTP
2386 (SSH File Transfer Protocol). Affected file in addition
2387 of the internet draft is lib/silccore/silcpacket.h.
2389 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2390 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2391 is used as part of backup router protocol when the primary
2392 router of the cell is back online and wishes to resume
2393 the position as primary router.
2395 * Redefined the MAC generation keys in the protocol. The
2396 same key is not used anymore in both direction. Both
2397 direction will now use different keys for sending and
2398 receiving. This fixes a potential security flaw. This
2399 change causes incompatibilities in the protocol.
2401 * Redefined also the MAC computation from the packet.
2402 An packet sequence number is now added to the MAC
2403 computation. This prevents possible replay attacks against
2404 the protocol. This change too causes incompatibilities
2407 Added `sequence' field to the SilcPacketContext to hold
2408 the current sequence number for the packet.
2410 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Added `created' field to the SilcIDListData in the file
2413 silcd/idlist.h to indicate the time when the entry was
2416 * Added `created' field to the SilcChannelEntry too. Affected
2417 file silcd/idlist.h.
2419 * Added `creation_time' aguments to all the announcement functions
2420 in the server. If it is provided then only the entries that
2421 was created after the provided time frame are actually
2422 announced. Affected file silcd/server.[ch].
2424 * The protocol says that the Channel ID's IP address must be
2425 based on the router's IP address. Added check for this in
2426 the silc_server_new_channel when processing incoming New Channel
2427 Payload. Affected file silcd/packet_receive.c.
2429 * Print out the correct version with --version in SILC client.
2430 Affected file irssi/src/silc/core/silc-core.c.
2432 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Fixed WHOWAS command to check for completnes of the client
2435 entry always, not just when the command is coming from client.
2436 Affected file silcd/command.c.
2438 * Added new function silc_server_packet_queue_purge to purge the
2439 outgoing data queue to the network. After the function returns
2440 it is guaranteed that the outgoing packet queue is empty.
2441 Affected file silcd/packet_send.[ch].
2443 * Purge the outgoing packet queue in the rekey protocol's final
2444 callback to assure that all rekey packets go to the network
2445 before quitting the protocol. Affected file silcd/server.c.
2447 * Added silc_client_packet_queue_parse as similar function as
2448 in server to the client library. The affected file is
2449 lib/silcclient/client.c.
2451 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Splitted silcd/server.c and created silcd/server_util.[ch]
2454 for utility functions.
2456 * Added new socket flag SILC_SF_DISABLED to indicate that the
2457 connection is open but nothing can be sent to or received from
2458 the connection. Affected file lib/silcutil/silsockconn.[ch].
2459 The checking for disabled socket is checked in the low level
2460 silc_socket_write and silc_socket_read functions.
2462 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Allow only nicknames and channel names that fits into the
2465 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2467 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * When processing JOIN command reply in server check that if
2470 the channel exists in our global list we'll move it the local
2471 list. Affected file silcd/command_reply.c.
2473 * Fixed the check whether client is joined on the channel already
2474 in JOIN command. Affected file lib/silcclient/command.c.
2476 * Fixed the JOIN command reply to check whether the channel
2477 already exists. Affected file lib/silcclient/command_reply.c.
2479 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Added silc_ske_status_string to map the SKE error numbers
2482 to readable strings. The affected files are
2483 lib/silcske/silcske[_status].[ch].
2485 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Do not show the private channels on the WHOIS channel list
2488 as it is not allowed by the protocol. The affected file is
2491 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Assure that the packet length digged from the actual packet
2494 is something sensible in the silc_packet_decrypt_rest_special
2495 in lib/silccrypt/silcpacket.c.
2497 * Free and NULL the allocated pointer in silc_hmac_alloc if
2498 the HMAC allocation fails. The affected file is
2499 lib/silccrypt/silchmac.c.
2501 * Print the selected security properties to the log files in
2502 the server. Affected file silcd/protocol.c.
2504 * Add SKE's reference counter even if calling the completion
2505 callback manually. Otherwise it goes negative, although it
2506 does not cause any problems. The affected file is
2507 lib/silcske/silcske.c.
2509 * Remove the client entry with short timeout after giving the
2510 KILL command. Affected file lib/silcclient/command.c.
2512 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2513 case all found clients are already disconnected (WHOWAS would
2514 found them) in the server. Affected file silcd/command.c.
2516 * Update the last_receive (time of last data received) to be
2517 updated only when received private or channel message so that
2518 the idle time showed in WHOIS makes more sense.
2520 * Added boolean field `valid' in to the SilcClientEntry in the
2521 client library to indicate whether the entry is valid or not.
2522 This fixes the nickname change bug on channel when changing
2523 the nickname to be same than the old (like nick to Nick) the
2524 nickname formatter doesn't set the new nick anymore to Nick@host.
2525 Affected file lib/silcclient/idlist.[ch].
2527 * Now actually fixed the nickname changing on disconnection.
2528 Added new function silc_change_nick to the Irssi SILC Client.
2529 Affected file irssi/src/silc/core/client_ops.c,
2530 irssi/src/silc/core/silc-nicklist.[ch].
2532 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Check that the public key exists in the GETKEY command before
2535 trying to encode it. Affected file silcd/command.c.
2537 * Print some notifications on received public keys with GETKEY
2538 command in the Irssi SILC Client. Affected files are
2539 irssi/src/fe-common/silc/module-formats.[ch],
2540 irssi/src/silc/core/client_ops.c.
2542 * Use IDENTIFY command to resolve the server information in the
2543 GETKEY command instead of INFO command. Affected file
2544 lib/silcclient/command.c.
2546 * All command reply functions in the client library now calls
2547 the pending command reply callbacks even if an error has
2548 occurred. The server has done this a long time and now it was
2549 time to move the client library to this as well. Now all
2550 errors can be delivered back to the pending command reply
2551 callbacks if necessary. Affected files are
2552 lib/silcclient/command[_reply].[ch].
2554 * Change the nickname on disconnection back to the username
2555 because in reconnect the server will enforce it to it anyway.
2556 Affected file irssi/src/silc/core/silc-servers.c.
2558 * Fixed a config file parsing bug in the Irssi SILC client.
2559 Affected file irssi/src/silc/core/clientconfig.c.
2561 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * When printing the channel mode on JOIN, verify that the
2564 channel key and channel's HMAC are valid. Affected file
2565 irssi/src/silc/core/client_ops.c.
2567 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2570 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2571 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2573 * Removed channel key rekey task deleting from the function
2574 silc_server_save_channel_key. Affected file silcd/server.c.
2575 Added explicit timeout task context instead that is used to
2576 delete the task if we are registering a new task before the
2577 new task has elapsed.
2579 * When channel key rekey occurs the client library now saves
2580 the old channel key for a short period of time (10 seconds) and
2581 is able to use it in case some is still sending channel
2582 messages encrypted with the old key after the rekey. Affected
2583 file lib/silcclient/[idlist.h|client_channel.c].
2585 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Added check to the silc_server_new_id_real to not accept
2588 new ID if it is the sender's own ID. Affected file is
2589 silcd/packet_receive.c.
2591 * Assure that we do not announce ourself or the one we've
2592 sending our announcements when we're router and are announcing
2593 servers to our primary router. Affected file silcd/server.c.
2595 * Fixed silc_server_command_identify_check_client to assemble
2596 correct WHOIS packet. It send corrupted WHOIS packet and
2597 caused problem with router to router connections. Affected
2598 file silcd/command.c.
2600 Fixed also silc_server_command_whois_check the same way
2601 as for the IDENTIFY command.
2603 * Added new SilcIDListStatus to the server in the SilcIDListData
2604 structure. The status now includes the current status of
2605 the entry (like registered, resolved etc.). Affected file
2606 silcd/idlist.[ch]. Defined a bunch of different status types
2607 as well. This replaced the old boolean registered field as well.
2609 Added resolve_cmd_ident field to the SilcClientEntry structure
2610 too so that if the entry is for example being resolved so
2611 another command may attach to the same pending command reply
2612 without requiring to resolve the same entry again. This concept
2613 should optimize the WHOIS and the IDENTIFY resolving under
2614 heavy load by taking away unnecessary resolving for entries
2615 that are being resolved already.
2617 Added support for adding multiple pending commands for one
2618 command idenfier. Affected file silcd/command[_reply].[ch].
2620 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2621 before deleting the data. Otherwise the hash table will have
2622 freed data in comparison functions. Affected file is
2623 silcd/command_reply.c.
2625 * Fixed silc_idlist_replace_client_id to add the new entry to
2626 the cache with NULL nickname. Otherwise there will be invalid
2627 memory as the nickname after the nickname is freed. Affected
2628 file silcd/packet_receive.c.
2630 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2631 saved into wrong slots because the previous number of entries
2632 was not taken into account. Affected file silcd/idlist.c.
2633 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2635 * If we are router and we receive JOIN notify to a channel that
2636 does not have any users then notified client is marked as the
2637 channel founder, as it is it. The affected file is
2638 silcd/packet_receive.c
2640 * Added to the extended hash table API's table_del_*ext functions
2641 the destructor as argument too, so that the caller can decide
2642 which destructor to use or whether to use destructor at all.
2643 Affected file lib/silcutil/silchashtable.[ch].
2645 * Fixed ID Cache purging. It actually deleted the entries from
2646 the hash table after the data was freed. The hash table ended
2647 up comparing freed memory. The affected file is
2648 lib/silccore/silcidcache.c.
2650 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Fixed Irssi SILC client's KILL command's HELP syntax.
2654 * The USERS command now resolves the detailed user information
2655 if the userinfo field is missing. Affected file is
2656 lib/silcclient/command_reply.c.
2658 * Do not print error in silc_file_read if the read file does
2659 not exist. Just silently return NULL. Affected file is
2660 lib/silcutil/silcutil.c.
2662 * Fixed the silc_log_output to not wine about NULL filename
2663 and to not create some bogus " " filename. Affected file is
2664 lib/silcutil/silclog.c.
2666 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Fixed various printing bugs on the user interface in the
2669 Irssi SILC Client. Minor changes that were forgotten from
2672 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Fixed the configure.in.pre and the compilation and distribution
2675 environment to support the new autoconf 2.52. That version is
2676 now required to compile the CVS trunk.
2678 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2681 to generally parse user@fqdn format strings. Affected file
2682 lib/silcutil/silcutil.c.
2684 * Added nickname_format and nickname_force_format fields to the
2685 SilcClientParams structure. The first one defines the format
2686 for the nicknames that the library will enforce if the receives
2687 multiple same nicknames. The second one is boolean value and
2688 can be used to force the library to always enforce the format
2689 to the nicknames regardles whether there are multiple nicknames
2690 or not. This configurable formatting was employed to flexibly
2691 support accessing multiple nicknames from the user interface.
2692 The userinterface can now set the nicknames to what ever format
2693 they prefer. Affected file lib/silcclient/silcapi.h.
2695 Added function silc_client_nickname_format to the file
2696 lib/silcclient/idlist.c. It performs the nickname formatting.
2698 Added new field `hostname´ to the SilcClientEntry context.
2699 It holds the hostname of the client. Affected file is
2700 lib/silcclient/idlist.h.
2702 * Irssi SILC Client sets the nicknames in nick@hostn format.
2703 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2704 irssi/src/silc/core/silc-core.c.
2706 The WHOIS printing now also shows both the real nickname and
2707 the formatted nickname so that user knows how to access the
2708 user if there are multiple same nicknames cached. Affected
2709 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2710 printing formatting too to take the hostname now as a separate
2711 argument. The Affected file is
2712 irssi/src/fe-common/silc/modules-formats.[ch].
2714 * Changed the silc_client_get_clients_local to accept the formatted
2715 nickname as argument. It accepts the real nickname too but the
2716 formatted nickname can be used to find the true entry from
2717 multiple entries. Affected file lib/silcclient/silcapi.h and
2718 lib/silcclient/idlist.c.
2720 * Added nickname_format_parse field to the SilcClientParams.
2721 It is a callback function provided by the application to parse
2722 the nickname out of the formatted nickname string. The library
2723 calls it to get the nickname from the formatted string. Since
2724 the application generally knows better the format of the nickname
2725 string it parses it instead of the library, even though library
2726 encodes the formatted string. If the callback function is not
2727 provided then the library will use the string as is. The
2728 affected file is lib/silcclient/silcapi.h.
2730 * All the nickname strings passed to the client library in
2731 commands are now expected to be formatted nickname strings.
2732 If the command does not support the formatted nickname string
2733 it will assume that the sent string is the actual nickname.
2734 Affected file lib/silcclient/command.c.
2736 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Added public key authentication support to OPER and SILCOPER
2739 commands in the client library. Affected file is
2740 lib/silcclient/command.c.
2742 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2744 * Changed the get_auth_methdod client operation to be asynchronous.
2745 It can be async if the application resolves the authentication
2746 method from the server during the negotiation. Added new
2747 SilcGetAuthMeth completion callback that the application will
2748 call after resolving the authentication method.
2750 Added function silc_client_request_authentication_method that
2751 the application can use to resolve the authentication method
2752 from the server. Added also SilcConnectionAuthRequest callback
2753 that the library will call after the server has replied. The
2754 application can call this function if it does not know the
2755 current authentication method.
2757 Affected files are lib/silcclient/client.c and
2758 lib/silcclient/silcapi.h.
2760 * The Irssi SILC client now automatically resolves the authentication
2761 method incase any configuration information is not present (and
2762 currently there never is). The affected file is
2763 irssi/src/silc/core/client_ops.c.
2765 * Fixed public key authentication from the client library.
2766 Affected file lib/silcclient/protocol.c. Changed also the
2767 protocol specification about the public key authentication in
2768 the connection authentication protocol. The actual data to be
2769 signed is now computed with a hash function before signing.
2771 * Fixed the public key authentication from the server as well.
2772 Affected file silcd/protocol.c.
2774 * Removed the mlock()'s from the memory allocation routines.
2775 Affected file lib/silcutil/silcmemory.c. The ./configure does
2776 not check anymore for the mlock(). Affected file is
2779 * Fixed USERS command in server to allow the execution of the
2780 command for private and secret channels if the client sending
2781 the command is on the channel. Affected file silcd/command.c.
2783 * Fixed silc_client_get_clients_local to return the clients
2784 count correctly. It could return wrong value. Affected file
2785 lib/silcclient/idlist.c.
2787 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2790 types. The assembler optimizations seemed not to like 64-bit
2791 data types. The assmebler optimizations thus are now enabled
2792 also for BSD systems as opposed to only enable them for Linux.
2794 * Do not check for threads at all on BSD systems. Affected
2795 file configure.in.pre.
2797 * Removed -n and -h options from the Irssi SILC Client since
2798 they are not used in silc.
2800 * Fixed the prime generation to assure that the first digit
2801 of the generated random number is not zero since our conversion
2802 routines does not like number strings that starts with zero
2803 digit. If zero digit is seen the random number is regenerated.
2804 This caused some corrupted RSA keys when the zero first digit
2805 was met. Affected file lib/silcmath/silcprimegen.c.
2807 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Fixed WIN32 configuration in the ./configure script.
2810 Fixed to include xti.h on environments that has it.
2811 Patches by Carsten Ilchmann and andrew.
2813 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Changed the silc_id_create_client_id to be collision
2816 resistant. It is now assured that there cannot be created
2817 two same client ID's. I suspect that some weird bugs in
2818 the server were actually caused by duplicate Client IDs.
2819 Affected file silcd/serverid.[ch]. A router receiving
2820 new ID now also assures and informs the sending server
2821 if the ID caused collision.
2823 * Changed the silc_id_create_channel_id to also assure that
2824 there are no collisions.
2826 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Statement about ignoring the Mutual Authentication flag when
2829 performing rekey with PFS was a bit misleading. It is ignored
2830 if it was set in the initial negotiation, it cannot be even
2831 set in the rekey. Fixed in the ke-auth draft. Started the
2832 new versions of the protocol drafts in the doc/.
2834 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Fixed a bug in silc_client_command_identify_save when saving
2837 new channel information. The channel name was no duplicated
2838 and caused crash on exit. Affected file is
2839 lib/silcclient/command_reply.c.
2841 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Fixed the getkey command handling in the server. Send just
2844 empty OK reply to the sender if the key could not be fetched
2845 (but everything else was ok, like the key just was not available).
2846 Changed the public key parameter to optional in the protocol
2847 specs so that empty OK reply can be sent. Affected file
2850 Added a message to Irssi SILC client to tell to user if the
2851 server did not return a public key.
2853 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Fixed a channel key regeneration bug. It registered new
2856 timeout tasks exponentially until all system resources were
2857 used. Affected file silcd/server.c.
2859 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * Added the SILC Document generator to the scripts/silcdoc.
2862 It can be used to generate the Toolkit Reference Manual out
2863 of the source tree. Internally it will also use the RoboDoc
2864 generator now imported in util/robodoc.
2866 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Added couple of return's in rekey protocol if error orccurred
2869 during the protocol. The execution must be terminated.
2870 Affected file silcd/protocol.c. Also, terminate the protocol
2871 always with timeout.
2873 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * The client's Client ID was created initally from the wrong
2876 nickname (it could have been in format nick@host) in the
2877 silc_server_new_client. Affected file silcd/packet_receive.c
2879 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Added some SILC_LOG_ERROR's to various error conditions
2882 if client could not be added to ID cache. Affected files
2883 silcd/packet_receive.c and silcd/server.c.
2885 * When client's sock->user_data is freed, NULL also the
2886 client->router and client->connection pointers. Added check
2887 for these pointers being NULL to various places around the
2888 code. Affected file silcd/server.c.
2890 * Added client->data.registered == TRUE checks to various
2891 places around the code to assure that unregistered client's
2892 are not handled when it is not allowed. Affected file
2895 * Added `bool registered' fields to all
2896 silc_idlist_[server|client]_get_* routines to indicate whether
2897 the fetched client needs to be registered or not. Affected
2898 file silcd/idlist.[ch].
2900 * Add your own entry as registered to the ID cache in the
2901 server. Affected file server.c.
2903 * Fixed a bug in silc_server_new_server. The SilcServer was
2904 set as the new server's context instead of SilcServerEntry.
2905 This naturally caused some weird bugs.
2907 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2909 * Do not delete the channel rekey task when adding it
2910 for in silc_server_create_channel_key.
2912 * Changed the silc_server_create_channel_key to return
2913 TRUE or FALSE to indicate the success of the channel key
2916 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Fixed MSVC++ project files and added missing files to
2919 Makefiles under win32/.
2921 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Do not add TCP_NODELAY flag if the operating system
2924 does not have it defined. Affected files are
2925 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2927 * Fixed buffer overflow from Irssi SILC Client. Affected
2928 file irssi/src/fe-common/core/themes.c.
2930 * Fixed double free in client library in the file
2931 lib/silcclient/client.c when disconnecting from server.
2933 * Applied double free patch from cras to Irssi SILC client.
2934 Affected files irssi/src/core/[modules/expandos].c
2936 * Fixed the disconnection handling to Irssi SILC Client.
2937 The application must call silc_client_close_connection
2938 in ops->connect client operation in case of failure of
2939 the connection. Affected file is
2940 irssi/src/silc/core/client_ops.c.
2942 * Do not set sock->protocol to NULL in the function
2943 silc_client_close_connection after executing the protocol's
2944 final callback since the sock might not be valid anymore.
2945 Affected file lib/silcclient/client.c.
2947 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * Do not enable SILC_THREADS if the linking with libpthread
2950 did not happen. Affected file configure.in.pre.
2952 * Added notion to protocol specification that server must
2953 verify the sent authentication payload with CMODE when
2954 setting the channel founder key. Implemented it to the
2955 server. Affected file silcd/command.c.
2957 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Added _EXTRA_DIST SILC distribution variable to the
2960 distributions file. It is used to conditionally add extra
2961 files or directories to the specific distribution. Affected
2962 files ./prepare, Makefile.am.pre and distributions.
2964 Removed the `_' from the start of the distribution names.
2967 * Added README.WIN32 for instructions to compile the Toolkit
2970 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Fixed a double free in disconnection in the server. Affected
2973 file is silcd/server.c.
2975 * Fixed the lib/silcske/groups.c to work now also with GMP
2976 MP library. The string conversion did not work when using
2977 specific base and the base is indicated in the string as well.
2979 * Created win32/ directory which now includes MSVC++ specific
2980 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2981 It will appear only in the toolkit distribution
2983 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Changed the key material distribution function in case when
2986 the hash output is too short. The data is now concatenated
2987 a bit differently than it used to. Made the change to the
2988 SKE protocol specification.
2990 * Added better GMP detection to configure.in.pre. A patch
2993 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Fixed a minor bug in SKE that might cause some problem on
2996 some platforms. Affected file lib/silcske/silcske.c.
2998 * Added the cookie checking for initiator in the SKE. It checks
2999 that the responder returns the sent cookie unmodified. The
3000 affected file is lib/silcske/silcske.c. Added new SKE
3001 error type INVALID_COOKIE that can be sent during the
3002 negotiation. Fixed some memory leaks as well.
3004 * Added the "invalid cookie" error message to Irssi SILC client's
3007 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Added `task_max' field to the SilcClientParams to indicate
3010 the maximum tasks the scheduler can handle. If set to zero,
3011 default values are used. Affected file lib/silcclient/silcapi.h.
3013 * Fixed memory leaks in silc_client_close_connection. Affected
3014 file lib/silcclient/client.c.
3016 * Added silc_client_del_client_entry to client library to free
3017 all memory of given client entry. Affected file is
3018 lib/silcclient/idlist.[ch].
3020 * Added new functions silc_client_del_channel and
3021 silc_client_del_server to delete channel and server entries.
3022 Affected file lib/silcclient/[silcapi.h/idlist.c].
3024 * Removed silc_client_del_client_by_id from silcapi.h.
3026 * Fixed the INFO command to return the server's own info
3027 correctly when querying by Server ID. Affected file is
3030 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * Removed the non-blocking settings in WIN32 code in the
3033 silc_sock_[read/write] and added SleepEx instead. Affected
3034 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3035 of input data is now checked with FIONREAD and ioctlsocket.
3037 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * Call silc_schedule_task_del_by_context in the
3040 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3041 Affected file lib/silccore/silcprotocol.c.
3043 * Call silc_protocol_cancel for active protocols in the
3044 silc_server_close_connection if the funtion
3045 silc_server_free_sock_user_data has not been called.
3046 Affected file silcd/server.c.
3048 * Generic tasks cannot be deleted using the del_by_fd
3049 task deleting function since generic tasks does not match
3050 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3052 * Added a notion to SILCOPER help file that the SILCOPER works
3053 only on router server, not on normal server.
3055 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Added for WIN32 support for the new scheduler as well.
3058 Affected file lib/silcutil/win32/silcwin32schedule.c.
3060 * Fixed the SHA1 implementation to work on various platforms.
3062 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3064 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3065 API. It is part of the scheduler now. Everything else is
3066 as previously but some functions has changed their names.
3067 Checkout the lib/silcutil/silcschedule.h for the interface.
3068 Updated all applications to use the new interface. Affected
3069 files are lib/silcutil/silcschedule.[ch].
3071 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Found a bug in the SKE implementation. The HASH value,
3074 specified by the protocol, was not computed correctly. The
3075 public key of the responder was not added to the computation
3076 even though it is mandatory. Affected file lib/silcske/silcske.c.
3077 This unfortunately causes incompatibilities with older
3078 clients and servers.
3080 * Added WIN32 specific network init and uninit functions:
3081 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3082 the Winsock2. Affected file lib/silcutil/silcnet.h and
3083 lib/silcutil/win32/silcwin32net.c.
3085 * Set the socket always to nonblocking mode on WIN32 after
3086 reading data or writing data. Affected file is
3087 lib/silcutil/win32/silcwin32sockconn.c.
3089 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3091 * Fixed various compilation problems under WIN32. Affected
3092 files lib/silcutil/win32/silcwin32thread.c and
3093 lib/silcutil/win32/silcwin32schedule.c.
3095 * Removed all _internal.h #includes from public header
3096 files. Internal headers must never be included from
3099 Removed also the lib/silcske/payload_internal.h file.
3101 * All include files that may be needed (public and some others
3102 included by the public headers) by application developers are
3103 now copied to the ./includes directory. It does not copy any
3104 internal headers. Affected file Makefile.defines.pre and all
3105 Makefile.am's under lib/ and subdirs.
3107 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Do not change the ~/.silc directory's permissions automatically.
3110 Affected file irssi/src/silc/core/clientutil.c.
3112 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Do not cancel the protocol in silc_server_close_connection
3115 it might cause recursion. Now cancelled in the function
3116 silc_server_free_sock_user_data. Affected file silcd/server.c.
3118 * Fixed the silc_server_remove_clients_by_server to regenerate
3119 the channel keys correctly finally. Added also new function
3120 silc_server_remove_clients_channels to actually do it.
3121 Affected file silcd/server.c.
3123 * Fixed the silc_server_new_channel to not crash by giving
3124 wrong router to the new channel. Affected file is
3125 silcd/packet_receive.c.
3127 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3130 which is given as argument to the silc_client_alloc now.
3131 It can be used to configure the client and set various parameters
3132 that affect the function of the client.
3134 * The USERS command in server did not check whether the channel
3135 is private or secret. Affected file silcd/command.c.
3137 * Added new argument to the USERS command in protocol specification.
3138 The USERS command now can take the channel name as argument
3139 as well. Added support for this in client and server and
3140 updated the protocol specs.
3142 * Completed the GETKEY command in client. It can be now used
3143 to fetch also servers public key not only some clients.
3144 Affected files lib/silcclient/command[_reply].c.
3146 * Added silc_client_get_server to return server entry by the
3147 server name. Affected files lib/silcclient/silcapi.h and
3150 * Redefined the IDENTIFY command in protocol specification to be
3151 more generic. It now can be used to query information about
3152 any entity in the SILC Network, including clients, servers and
3153 channels. The query may be based either the entity's name
3154 or the ID. Added support for this in both client and server.
3156 Affected files silcd/command.c and lib/silcclient/command.c
3157 and command_reply.c.
3159 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3160 the _from_client and _from_server functions. Affected file
3163 * Added silc_client_get_channel_by_id_resolve to the file
3164 lib/silcclient/silcapi.h to resolve channel information by
3165 its ID. Added also silc_client_get_channel_by_id that
3166 does not resolve it from the server.
3168 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Added SilcServerEntry context into the client library
3171 to represent one server. The INFO command now allocates
3172 these to save the resolved server info. For now on the
3173 client library will also keep information about servers,
3174 connected and resolved with INFO.
3176 The INFO command now allocates the SilcServerEntry context
3177 and saves the server info there. The COMMAND_REPLY in
3178 the INFO now returns the parameters to application in
3179 same order as defined in the protocol specification.
3181 The entries are cached in the client->server_cache.
3183 * The INFO command is now issued after received the Client ID
3184 from the server. Affected file lib/silcclient/client.c.
3186 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3187 to the application as the mode changer might be server.
3188 It is guaranteed that NULL is not returned anymore to the
3189 application. Affected file lib/silcclient/client_notify.c.
3191 The ID Type is now also passed to the application so that
3192 it can check whether the returned entry is SilcClientEntry
3195 Added new function silc_client_get_server_by_id to return
3196 the server entry by ID. Affected files are the
3197 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3199 * Do not create the channel in the Irssi SILC Client when issuing
3200 the JOIN command but when received the sucessful JOIN command
3201 reply. Otherwise the channel might get created even though we
3202 could not join it. The Affected file is
3203 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3205 * Fixed a channel joining bug in router. The router must also
3206 check the channel modes, invite and ban lists etc. when serving
3207 the JOIN command sent by normal server. Affected file is
3208 silcd/command.c. The router now resolves the client's
3209 information from the server who sent the JOIN command if it
3210 does not know it, and processes the JOIN command only after
3213 * Changed the SilcCommandCb to take new argument; void *context2.
3214 Affected file lib/silccore/silccommand.h
3216 The second argument in the command callbacks in the server now
3217 includes the SilcServerCommandReplyContext if the command was
3218 called as pending command callback from the command reply.
3219 Otherwise it is NULL. When called as pending the status of the
3220 command reply will be checked and if it was erronous the
3221 error will be sent to the original sender of the command.
3222 This way the client always receives the error messages even
3223 though the server was actually the one who received the error
3224 when it resent the command to router, for example. Affected
3225 files silcd/command[_reply].[ch].
3227 * Fixed sending WHOWAS command's error message to client if
3228 the requested client could not be found. It was missing.
3231 * Changed the CMODE and CUMODE commands reply arguments in the
3232 protocol specification. The Channel ID is now sent in both
3233 of the commands to identify the channel. Implemented this
3234 new feature to the client and server. Affected files
3235 lib/silcclient/command_reply.c and silcd/command.c.
3237 * Made better checks for invite and ban lists in the JOIN
3238 command in server. Affected file silcd/command.c.
3240 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * The server now performs the incoming host IP/DNS lookup
3243 using the silc_socket_host_lookup and thus does not block
3244 the server anymore. Affected file silcd/server.c.
3246 * Completed the multi-thread support for SILC Scheduler in
3247 the lib/silcutil/silcschedule.c.
3249 * Fixed the configure.in.pre to detect the pthread correctly
3252 * Fixed a deadlock in silc_task_queue_wakeup in the file
3253 lib/silcutil/silctask.c.
3255 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3257 * Added new function silc_schedule_wakeup that is used in
3258 multi-threaded environment to wakeup the main thread's
3259 schduler. It needs to be used when a thread adds a new task
3260 or removes a task from task queues. After waking up, the
3261 scheduler will detect the task queue changes. If threads
3262 support is not compiled in this function has no effect.
3263 Implemented the wakeup mechanism to both Unix and WIN32
3264 systems. Affected files are lib/silcutil/silcschedule.[ch],
3265 lib/silcutil/unix/silcunixschedule.c and the
3266 lib/silcutil/win32/silcwin32schedule.c.
3268 * Added new function silc_task_queue_wakeup to wakeup the
3269 scheduler by the specified task queue. Affected file
3270 lib/silcutil/silctask.[ch].
3272 * The silc_socket_host_lookup_start now wakes up the scheduler
3273 after adding the timeout task. Affected file is
3274 lib/silcutil/silcsockconn.c.
3276 * The silc_socket_host_lookup is synchronous now if the threads
3277 support is not compiled in. However, the callback is still
3278 called asyncronously through the scheduler, anyway. Affected
3279 file lib/silcutil/silcsockconn.c.
3281 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3283 * Added new function silc_socket_host_lookup to perform
3284 asynchronous IP and FQDN lookups for the socket connection.
3285 Affected files lib/silcutil/silcsockconn.[ch].
3287 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3290 that may or may not compile the mutex support in.
3292 Changed the silc_mutex_alloc interface. It allocates the
3293 mutex now to the sent pointer and returns TRUE or FALSE.
3295 Affected file lib/silcutil/silcmutex.h.
3297 * Wrote the SILC Task Queue interface to support multi-threads.
3298 Affected file lib/silcutil/silctask.[ch].
3300 * Wrote the SILC Scheduler to support multi-threads. Affected
3301 file lib/silcutil/silcschedule.c.
3303 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3306 in lib/silcutil/win32/.
3308 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3310 * Defined SILC Mutex API and SILC Thread API and implemented
3311 them for Unix. Affected files are
3312 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3313 lib/silcutil/unix/silcunixmutex.c and
3314 lib/silcutil/unix/silcunixthread.c.
3316 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Fixed the silc_server_remove_clients_by_server's channel
3319 key re-generation. The hash table handling was incorrect
3320 and would not work with many channels. Affected file is
3323 * Fixed some memory leaks around the server code.
3325 * Rewrote the silc_server_get_users_on_channel to support IPv6
3326 based Client ID's. Affected file silcd/server.c.
3328 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3329 specification. However, a separate document must be written
3330 to define the detailed signing procedure and the payload
3331 associated with the flag. Defined the flag to the
3332 lib/silccore/silcchannel.h as well.
3334 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * Changed the dynamic tables to static size tables in the
3337 lib/silccrypt/silchmac.c.
3339 * Removed GCC dependencies from the code. A patch by cras.
3341 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Do not show the error "Error receiving packet bla bla"
3344 in server if it really was not an error (-2 means that reading
3345 is pending). Affected file silcd/server.c.
3347 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Fixed a possible crash in silc_server_remove_clients_by_server
3350 in silcd/server.c. Fixed there also some memory leaks.
3352 * Fixed the silc_idlist_replace_client_id. It could replace
3353 wrong key in the hash table. Affected file silcd/idlist.c.
3355 * Do not check whether there are global users on the channel
3356 if the channel->global_users is FALSE. Affected functions
3357 silc_server_remove_from_one_channel and
3358 silc_server_remove_from_channels in silcd/server.c. Also,
3359 do not check if the removed client is local as we can be
3360 sure that global client was not removed from the channel
3361 and checking for global users is not needed.
3363 * The silc_server_remove_clients_by_server now re-generates
3364 the channel keys correctly for those channels that had
3365 clients removed from them. Affected file silcd/server.c.
3367 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Found the reason of random crashes in the server. We weren't
3370 ignoring the SIGPIPE signal (which can be sent in write())
3371 and it crashed the server. Affected file silcd/silcd.c.
3373 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Assure that sock->user_data is not NULL in the function
3376 silc_server_packet_send in silcd/packet_send.c.
3378 * Disconnect the remote connection if it could not be added
3379 to any ID lists in the server. The affected file is
3382 * Check in silc_server_packet_send[_real/dest] that the
3383 socket is not disconnecting and ignore the data if it is.
3384 Affected file silcd/packet_send.c.
3386 * Define inline to __inline on native WIN32 compilation.
3387 Affected file includes/silcwin32.h.
3389 * Added some explicit type casts for inline code since MSVC
3390 require them. Affected files lib/silcutil/silcbuffer.h,
3391 lib/trq/silcdlist.h and lib/trq/silclist.h.
3393 * Print warning in log files from now on if the packet
3394 decryption fails. Affected file silcd/server.c.
3396 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3398 * Changed the `say' client operation's interface to accept
3399 new `type' argument to indicate the type of the message sent
3400 by the library. The application may filter the library's
3401 messages according the type. The affected file is the
3402 lib/silcclient/silcapi.h.
3404 * Added two new functions to lib/silcclient/silcapi.h:
3405 silc_client_del_client and silc_client_del_client_by_id.
3406 Affected file lib/silcclient/idlist.c.
3408 * Moved the clientincludes.h from includes/ to silc/ and
3409 serverincludes.h from includes/ to silcd/.
3411 * The modes for the CMODE and CUMODE are now passed as
3412 uint32 for application with COMMAND_REPLY. The affected
3413 file is lib/silcclient/command_reply.c.
3415 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3417 * /WHOIS without arguments shows client's own information.
3418 Affected file lib/silcclient/command.c.
3420 * Changed PING to not accept any arguments. The specs
3421 says that client can ping only the connected server so
3422 requiring an argument is not needed. Affected file is
3423 lib/silcclient/command.c.
3425 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * Fixed a fatal bug in private message sending and reception
3428 encryption and decryption when using private message keys.
3429 The implementation was incorrect and did not follow the
3430 specification. It causd that some of the message were
3431 lost since it did not use the sending and receiving keys
3432 as the protocol suggests. This has been fixed and will cause
3433 incompatibilities with older clients when sending private
3434 message encrypted with private message keys. Affected files
3435 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3436 and various other in Irssi SILC Client.
3438 Added `responder' boolean argument to the functions
3439 silc_client_add_private_message_key[_ske] to indicate when
3440 the key is added as responder or initiator of the key
3443 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Removed the silc_ske_check_version function and created
3446 a SilcSKECheckVersion callback. Added also a function
3447 silc_ske_set_callbacks that is now used to set all SKE
3448 callbacks. The callback functions are not given to
3449 the SKE functions anymore, but this function is used to
3452 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3454 * Added `silc_version' argument to the silc_client_alloc
3455 to define the version of the application for the library.
3456 The library will use the version string to compare it
3457 against the remote host's (usually a server) version
3458 string. Affected file lib/silcclient/silcapi.h
3460 * Added the KE protocol context to Key Agreement context
3461 in client library so that we can abort the SKE if it
3462 is in process when we get timeout. Affected file is
3463 lib/silcclient/client_keyagr.c.
3465 * Do not resolve the client ID forever if it returns in the
3466 first time that such client does not exist. This was done
3467 for example with private message. Affected file is
3468 lib/silcclient/client_prvmsg.c.
3470 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Do not add regex.h for WIN32. The affected file
3473 includes/silcincludes.h.
3475 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3476 not work yet 100%. It generates the DLL's automatically
3477 when compiling with --with-win32 under cygwin.
3479 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * lib/contrib/regex.c is not compiled on WIN32.
3483 * Added silc_net_get_socket_opt function to the
3484 lib/silcutil/silcnet.h.
3486 * Added includes/silcwin32.h for WIN32 specific includes
3489 * Do not use ptime structure or any of the posix process
3490 functions on WIN32 in lib/silccrypt/silrng.c.
3492 * Added silc_gettimeofday to provide generic function
3493 for struct timeval on all platforms. Added the function
3494 to lib/silcutil/silcutil.h.
3496 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3499 library as they clearly belong there. As a plus side we
3500 can make the actual socket connection routines platform
3503 Added also new generic function silc_socket_read and
3504 silc_socket_write (that used to be silc_packet_[read/write].
3505 The implementation of these are platform specific.
3507 * Added WIN32 specific routines of silc_socket_[read/write]
3508 to lib/silcutil/win32/silcwin32sockconn.c.
3510 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Added preliminary support for native WIN32 compilation under
3513 cygwin (using the -mno-cygwin option for GCC) to the
3514 ./configure.in.pre. The --with-win32 now prepares the
3515 compilation for native WIN32.
3517 * Rewrote the SILC Scheduler interface in the file
3518 lib/silcutil/silcschedule.h. The scheduler is now context
3519 based and does not have anymore any global static scheduler.
3520 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3521 and created lib/silcutil/win32 directory for WIN32 based
3524 * Added Unix specific network routines to the
3525 lib/silcutil/unix/silcunixnet.c and the old
3526 lib/silcutil/silcnet.c includes now only generic routines.
3528 Added WIN32 specific network routines to the
3529 lib/silcutil/win32/silcwin32net.c.
3531 * Added Unix specific utility functions from the
3532 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3534 * Added WIN32 SILC Scheduler to the file
3535 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3538 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Do not handle JOIN notify in the server if the target client
3541 is not registered (idata->registered == FALSE). The affected
3542 file is silcd/packet_receive.c.
3544 * Update the nickrec->founder in event_cumode in the Irssi SILC
3545 client. Affected file irssi/src/silc/core/silc-channels.c.
3547 * Fixed the CUMODE_CHANGE notify handling in the server when
3548 server and router are announcing their clients on channels.
3549 Now the mode changes are saved and notified correctly. The
3550 affected file is /silcd/packet_receive.c.
3552 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3553 They really did not replace the cache entry in the ID Cache.
3554 Now they do that. Affected file silcd/idlist.c.
3556 * Fixed the KICK notify handling in the Irssi SILC client to
3557 update the channel records so that the kicked client does not
3558 appear to be on the channel. The affected file is
3559 irssi/src/silc/core/silc-channels.c.
3561 * Always update the conn->current_channel when executing command
3562 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3564 * Fixed the KILL notify handling in Irssi SILC client to remove
3565 the killed client on all channels.
3567 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Fixed the silc_parse_command_line to remove extra spaces
3570 from the start and end of the arguments. Affected file is
3571 lib/silcutil/silcutil.c.
3573 * Cancel and free any active protocol in the function
3574 silc_server_close_connection. Affected file silcd/server.c.
3576 * Cancel and free any active protocol in the function
3577 silc_client_close_connction. Affected file is
3578 lib/silcclient/client.c.
3580 * Do not execute the KILL command for clients that are in
3581 history (ie. they are not in the network). Affected file is
3584 * Fixed KILL notify handling, client does not crash anymore.
3585 Affected file irssi/src/silc/core/silc-channels.c.
3587 * Reduced the default packet buffer size from 2048 to 1024 in
3588 lib/silccore/silcpacket.c.
3590 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3591 counter to the SKE context that is incresed when the SKE library
3592 performs async operation outside the library. If the outside
3593 process frees the SKE context and FREED status will be set
3594 and the library will detect after the sync operation that the
3595 libary is freed. The affected files are
3596 lib/silcske/silcske[_status].[ch].
3598 * Resolve the client entry information in the function
3599 silc_client_channel_message to assure that NULL pointer is not
3600 passed as client entry to the application. */
3602 * Fixed the task timeout calculation to assure that there is
3603 never negative timeouts. The affected file is
3604 lib/silcutil/silcschedule.c.
3606 * Fixed the channel user mode notification sending in server.
3607 It was sent point-to-point to the router (or to server by router)
3608 but it needs to be destined to a channel. The routines now
3609 supports sending the channel user mode notifys to the channels
3610 when announcing clients and channels. Affected files are
3611 silcd/server.c and silcd/packet_receive.c.
3613 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3614 It did not actually replace the old channel entry in the cache.
3615 Affected file lib/silcclient/client_notify.c.
3617 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Fixed a possible crash in silc_packet_send_prepare. It now
3620 assures always that there is enough space in the buffer and
3621 at the tail area of the buffer (for MAC).
3623 Fixed the inbound buffer reallocation in silc_packet_read.
3624 It was old code and did not handle the reallocation correctly.
3627 The affected file is lib/silccore/silcpacket.c.
3629 * Fixed buffer overflow in silc_parse_nickname in the file
3630 lib/silcutil/silcutil.c.
3632 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * make install generates new server keys only if there is not
3637 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3640 Added check that if the NOREPLY is set then we will not send
3641 the away message. This avoids infinite loop of away messages
3642 if both clients are away. The affected file is
3643 lib/silcclient/client_prvmsg.c.
3645 * Fixed client crash if /NICK was given without arguments.
3646 Affected file lib/silcclient/command.c.
3648 * Server does not send the invite list in INVITE command back
3649 to the client if the list was not altered. Added this notion
3650 to the protocol spec as well. Affected file silcd/command.c.
3652 Fixed possible crash in INVITE command by checking the
3653 value of silc_server_get_client_route command.
3655 * Fixed the INVITE notify type handling. The arguments are now
3656 taken in correct order and client does not crash. The affected
3657 file is irssi/src/silc/core/silc-channels.c.
3659 Removed the "Inviting xxx to channel" message from the
3660 client library away and let the application handle it.
3661 Affected file lib/silcclient/command.c. Added that message
3662 to Irssi SILC client's message formats.
3664 * Fixed CMODE command crash in client. It now checks the
3665 amount of arguments correctly and does not crash. The affected
3666 file is lib/silcclient/command.c.
3668 * Do not create new channel automatically in silc_channels_join
3669 but check whether the channel by that name already exists.
3670 Affected file irssi/silc/core/silc-channels.c.
3672 * Do not send the SERVER_SIGNOFF to router if the disconnected
3673 entity was the router. Affected file silcd/server.c.
3675 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3676 SILC client as it was missing from there.
3678 Added the handling of the KICK notify to the Irssi SILC client
3679 as it was missing. Added "you have been kicked" message to
3680 Irssi SILC client's message modules formats.
3682 Added the handing of the KILL notify to the Irssi SILC client
3683 as it was missing. Added the kill message module formats
3686 The affected file is irssi/src/silc/core/silc-channels.c.
3688 * The router did not save the channel mode the server announced.
3689 Affected file silcd/packet_receive.c.
3691 * Fixed a possible crash in INFO command in server. If the
3692 server did not provide the server info it crashed. Affected
3693 file silcd/command.c.
3695 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Fixed the GETKEY command in the server to check also the
3698 global list. Otherwise the GETKEY would not work correctly
3699 in normal SILC server. Affected file silcd/command.c.
3701 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Fixed GETKEY crash, it crashed if the command did not succseed.
3705 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3708 is now real and not just an macro interface to GMP.
3710 Removed the entire GMP from the source tree and imported new
3711 NSS MPI library instead. Reason for removing GMP is that it is
3712 extremely large and compiles extremely slow. The NSS MPI
3713 is only a few files and compiles in less than 10 seconds.
3714 The speed is also about the same as GMP. The MPI is imported
3715 to lib/silcmath/mpi.
3717 If the system has GMP installed we will still use the GMP.
3718 If it is not then the NSS MPI will be compiled.
3720 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Merged a long nickname (127 characters long) crash bugfix from
3723 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3725 * Merged a freed memory reference bugfix from Irssi CVS tree.
3726 Affected file irssi/src/core/commands.c.
3728 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Added the server's public key sving and verification to the
3731 server when performing the SKE. This was missing and the
3732 remote server's (or router's) public key was accepted without
3733 checking whether we have it previously or trust it at all.
3734 Affected file silcd/protocol.c.
3736 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Check in the silc_server_timeout_remote if protocol is active
3739 and make sure that the protocol's final callback is called so
3740 that all memory if freed. Affected file silcd/server.c.
3742 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * silc_server_whois_send_reply crashed the server if the nickname
3745 was 127 characters long. Affected file silcd/command.c.
3747 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Added sanity check to the silc_server_new_client. If the hostname
3750 is provided inside username then check that the provided hostname
3751 really is the same as the resolved one. If the hostname was not
3752 resolved then check it from the public key. Affected file is
3753 silcd/packet_receive.c.
3755 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3756 if the server disconnected us and the connection is not valid
3757 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3759 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3760 the library to the lib/silcutil/silcutil.[ch].
3762 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Close log file after open. Affected file
3765 lib/silcutil/silclog.c.
3767 * Check whether sock == NULL in silc_client_send_packet and return
3768 if it is. Affected file lib/silcclient/silcclient.c.
3770 * Check rec->entry == NULL in the Irssi SILC Client before
3771 sending the channel message. Affecte file is
3772 irssi/src/silc/core/silc-servers.c.
3774 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Merged a splitted window bugfix from Irssi CVS tree. The
3777 affected file is irssi/src/fe-text/textbuffer-view.c.
3779 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3780 It did not print nickname.
3782 * Improved the distributions system a bit.
3784 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3787 irssi/src/fe-text/gui-window.c.
3789 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3790 to in-active server. The affected file is
3791 irssi/src/silc/core/client_ops.c.
3793 * Resolve the client in USERS command reply if the entry does
3794 not have username resolved. The affected file is
3795 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3796 command to WHOIS command to really resolve stuff. The USERS
3797 is not used any more in any critical section so WHOIS can
3798 be used even though it might be slower than IDENTIFY.
3800 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3803 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Changed the protocol API a bit more consistent in the
3806 lib/silccore/silcprotocol.[ch].
3808 * Changed the following headers to ROBODoc format:
3810 lib/silccore/silcpayload.h
3811 lib/silccore/silcprotocol.h
3812 lib/silccore/silcsockconn.h
3814 All core library headers are now formatted.
3816 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Fixed a bug in Irssi SILC client; do not show that you are
3819 server/router operator if you really are not. Affected file is
3820 irssi/src/silc/core/client_ops.c.
3822 * Renamed silc_command_free_payload to silc_command_payload_free.
3823 Affected file lib/silccore/silccommand.h
3825 * Added silcmath.h to include the prototoypes of various routines
3826 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3829 * Changed the following headers to ROBODoc format:
3831 lib/silccore/silcchannel.h
3832 lib/silccore/silccommand.h
3833 lib/silccore/silcid.h
3834 lib/silccore/silcidcache.h
3835 lib/silccore/silcmode.h
3836 lib/silccore/silcnotify.h
3837 lib/silccore/silcpacket.h
3838 lib/silcmath/silcmath.h
3840 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Added checking to the server code not to start the server if
3843 ciphers and stuff are not configured properly. Affected files
3844 silcd/serverconfig.[h] and silcd/server.c.
3846 * Changed the layout of the header files of the public interfaces
3847 in the SILC libraries. The new layout supports ROBODoc
3848 documentation tool (and some others) so that it is easy to create
3849 a library reference manual. All the other headers and source
3850 code must still follow the CodingStyle document. Also source
3851 code must not include these ROBODoc stuffs, only the headers.
3852 Furthermore, all public interface headers must now be named
3853 by using `silc' prefix, example: silcapi.h, silccipher.h.
3854 Some files were renamed due to this. All the other headers
3855 must not be used as public interfaces. I will update the
3856 CodingStyle document later. Changed following headers, so far:
3858 lib/silcclient/silcapi.h
3859 lib/silccore/silcauth.h
3860 lib/silccore/silcprivate.h
3861 lib/silccrypt/silcdh.h
3863 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Removed silc_client_packet_send_flush from the client library
3868 as it is not needed. Affected file lib/silcclient/client.[ch].
3870 * Added printing of message of unresolved authentication method
3871 to the Irssi SILC client. Added it to the module formats.
3872 Removed the same message from the client library.
3874 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added new distribution feature, DISTLABEL. Every distribution
3877 can define own preprocessor label that can be used in the
3878 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3879 file distributions, acconfig.h.pre and prepare.
3881 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Added Makefile.defines_int to include the actual definitions
3884 for Makefile.defines.in. Tested the new distribution system,
3885 created distributions and tested installation.
3887 * Added AWAY message printing to the Irssi SILC client. Added
3888 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3890 * Added SCONNECT command to call the SILC's CONNECT command.
3891 Cannot use CONNECT directly since Irssi uses that internally.
3892 Affected file irssi/src/silc/core/silc-servers.c.
3894 Added ACTION local command. It is same as ME command but takes
3895 the channel as mandatory argument.
3897 Rewrote some of the Irssi's help files to suite for SILC
3900 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Added Makefile.defines[.in] that should for now on be included
3903 in all Makefile.am file in the source tree. That file includes
3904 all common compilation definitions for SILC source tree.
3906 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Minor changes to the ./prepare script to change the package
3909 name according the distribution name to the configure.in.
3911 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Created new distribution system. Added file `distributions'
3914 that defines all the distributions that can be created out of
3915 the SILC source tree. The ./prepare script now reads that
3916 file to determine how to prepare the distributions. The
3917 first argument to the ./prepare is the name of the distribution
3918 and second is the version of the distribution. If given
3919 without arguments it creates the default (toolkit) distribution
3920 with the default version (defined in ./prepare).
3922 All Makefile.am files that are subject to the distributions
3923 are now named as Makefile.am.pre. These are ./Makefile.am
3924 and lib/Makefile.am. Others may be changed later.
3926 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Added invite list, ban list, some key management and connection
3929 error message printing to module formats in the Irssi SILC client.
3931 * Added new silc_client_set_away_message to set the away message
3932 that is back to the person who sent private message. The
3933 affected file lib/silcclient/silcapi.h and the
3934 lib/silcclient/client_prvmsg.c.
3936 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Fixed the private message sending in the Irssi SILC client,
3939 added local command KEY to the Irssi SILC client.
3941 Added key management and key agreement message formats to the
3942 irssi/src/fe-common/silc/module-formats.[ch].
3944 Added USERS (alias WHO) printing, server/router operator
3945 indication and LIST command printing to the module formats.
3947 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Fixed channel joining notify handling, cumode notify handling
3950 from Irssi SILC client.
3952 * Added SILC specific module-formats to the Irssi SILC client so
3953 that SILC specific message hilighting, colors etc is possible.
3954 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3956 Added channel mode, channel user mode, actions, notices,
3957 whois and whowas printing to the the module-formats.c.
3959 * Fixed a bug in channel deletion in the server. The channel
3960 is not left to the cache even if the channel founder auth mode
3961 is set when there are no users anymore on the channel. Affected
3962 file silcd/server.c.
3964 * The silc_net_localhost now resolves the entire hostname including
3965 the domain name. Affected file lib/silcutil/silcnet.c.
3967 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Changed the ask_passphrase client operation to be ascynchronous.
3970 It has now a completion callback and a context that the
3971 application must call after it has got the passphrase from
3972 the user. Affected files lib/silcclient/silcapi.h,
3973 lib/silcclient/protocol.c, lib/silcclient/command.c and
3976 Added SilcAskPassphrase callback that the application calls
3977 to deliver the passphrase to the library.
3979 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3980 The public key verification and especially a certificate
3981 verification is asynchronous procedure.
3983 Added new SILC_SKE_STATUS_PENDING status to indicate the
3984 request is pending and a callback will be called to finalize
3987 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3988 indicate that remote end did not send its public key (or
3989 certificate), even though we require it. Added check for this
3990 condition in the SKE. This was a security bug, now fixed.
3992 Defined new SilcSKEVerifyCbCompletion callback that is called
3993 when the verification process is completed.
3995 The affected files lib/silcske/silcske_status.h and
3996 lib/silcske/silcske.[ch].
3998 * Changed the verify_public_key client operation to be async
3999 as well. Defined SilcVerifyPublicKey callback that is used to
4000 indicate the success of the public key verification process.
4002 Changed the server and client to use the new async client
4005 * Changed the Irssi SILC client's internal scheduler to be called
4006 twice as many times as it used to be. As a result the client
4007 should be a bit faster now. Affected file is
4008 irssi/src/silc/core/silc-core.c.
4010 * Added support to Irssi SILC client of asynchronous public key
4011 verification and passphrase inquiry. Affected file is
4012 irssi/src/silc/core/silc-core.c.
4014 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Do not say "You have left channel %s" in client library.
4017 Moved it to the application. Affected files are
4018 lib/silcclient/command.c and silc/client_ops.c.
4020 * Fixed silc_client_get_clients. Command context was not
4021 duplicated and was freed memory in the callback. Affected
4022 file lib/silcclient/idlist.c.
4024 * Do not say "you are now talking..." on JOIN command in the
4025 client library. The appliation must handle it.
4027 * Do not say ".. changed topic to" in command reply in the
4028 client libary. The application must handle it.
4030 * Fixed TOPIC command sending in the client library.
4032 * Fixed a memory leak in silc_client_command_free in the file
4033 lib/silcclient/command.c.
4035 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Imported a modified version of Irssi client to the source tree.
4038 The Irssi will be used to create a new client called
4039 Irssi SILC. Imported to irssi/.
4041 Added silc_core_init_finish function to the Irssi. Affected
4042 file irssi/configure.in.
4044 A lot changes in the Makefile.ams around the irssi tree.
4046 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Do not rehash if the new size is same as the old size of the
4049 hash table, in the silc_hash_table_rehash*. The affected file
4050 lib/silcutil/silchashtable.c.
4052 * Replaced hash_table_del_by_context calls from the server
4053 (when channel->user_list and client->channels) to the
4054 hash_table_del as it is sufficient and faster.
4056 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Added silc_hash_table_list, silc_hash_table_get and the
4059 SilcHashTableList structure to provide an alternative way to
4060 traverse the hash table. The affected files are
4061 lib/silcutil/silchashtable.[ch].
4063 * Changed the server's idlist routines to use the hash table
4064 routines to optimize the code.
4066 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Replaced the client entry's `channel' list and channel entry's
4069 `user_list' list to hash tables for optimized lookup. Changed
4070 the code to use the hash table interface around the code.
4071 Affected file lib/silcd/idlist.[ch].
4073 * Added `auto_rehash' boolean argument to the function
4074 silc_hash_table_alloc to indicate whether the hash table should
4075 auto-rehash when it thinks is appropriate time. It will
4076 increase the hash table size if the there is twice as much
4077 entries in the table than the size of the table, and will
4078 decrease the size if there are twice as less entries than
4079 the size of the table.
4081 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4085 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * silc_idcache_purge_by_context deletes the entry now by context
4088 as it is supposed to do. Affected file lib/silccore/idcache.c.
4090 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4091 client is not anymore valid (WHOWAS givens the info) and not
4092 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4094 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Removed the `data' and `data_len' arguments from the ID Cache
4097 interfaces and added `name' argument. ID Cache does not handle
4098 anymore the binary data only a names associated with given ID.
4100 * When hashing a Client ID with silc_hash_id the entire ID is
4101 not hashed anymore, instead only the hash of the Client ID is
4102 hashed. This way we can access the Client ID from the cache
4103 with Client ID but with the hash of the ID (which is a hash of
4104 the nickname) as well without any difference in performance.
4106 Added also silc_idcache_find_by_id_one_ext to do one on one
4107 searching when we have the actual ID. Added also function
4108 silc_hash_client_id_compare. The affected files are
4109 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4111 * When hashing the name associated with a ID it is always done
4112 in lowercase. This way we can access the cache without worrying
4113 about case-sensitivity, even though, for example nicknames are
4116 * Fixed a bug in server with channel message sending. It put
4117 wrong ID type as destination ID. The affected file
4118 silcd/packet_send.c.
4120 * silc_idcache_del_by_context now deletes from all hash tables
4121 by context. Affected file lib/silccore/idcache.c.
4123 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Changed the client library to use the new ID Cache interface.
4126 Changes around the source tree.
4128 * Added silc_hash_table_rehash_ext to rehash with specific
4129 hash function. Affected file lib/silcutil/silchashtable.[ch].
4131 * Added silc_hash_string_compare to compare two strings in the
4132 hash table. Affected file lib/silcutil/silcutil.[ch].
4134 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Added new function silc_idcache_del_by_context into the
4137 lib/silccore/idcache.[ch].
4139 * Changed the server's ID list routines to use the new ID Cache
4140 interface. Changes around the source tree.
4142 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Added silc_hash_table_del[_by_context]_ext functions in to the
4145 lib/silcutil/silchashtable.[ch].
4147 Removed silc_hash_table_find_all* routines and added new
4148 silc_hash_table_find_foreach to replace them.
4150 Added silc_hash_table_replace_ext function as extended
4151 replacing function. Separated the simple hash table interface
4152 from the extended hash table interface in the file
4153 lib/silcutil/silchashtable.h.
4155 * Fixed minor bugs and changed it to use some of the new
4156 hash table functions in lib/silccore/idcache.c
4158 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Added new function silc_hash_table_find_all to return all keys
4161 in the hash table by the specified key. As the hash table is
4162 collision resistant it also makes it possible to have several
4163 duplicate keys in the hash table. This function may be used to
4164 find all of the keys from the hash.
4166 Added user_context arguments to the SilcHashFunction,
4167 SilcHashCompare and SilcHashDestructor to deliver user specified
4170 Added new fuctions silc_hash_table_find[_all]_ext to do
4171 extended lookup with specified hash and compare functions and
4172 specified user contexts.
4174 Added new function silc_hash_table_add_ext to add the key
4175 with specified hash function and user context.
4177 Added new function silc_hash_table_foreach to traverse all
4178 entrys in the hash table. Added SilcHashForeach callback
4181 Added new function silc_hash_table_del_by_context to delete
4182 the entry only if the context associated with the key matches.
4184 Affected files are lib/silcutil/silchashtable.[ch].
4186 * Removed silc_hash_[server/client/channel]_id and added just
4187 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4188 silc_hash_id_compare to compare two ID's using as the hash table
4189 comparison function. Added also silc_hash_data to hash
4190 binary data and silc_hash_data_compare to compare it.
4192 * Removed silc_idlist_find_client_by_hash as it is not needed
4193 anymore. Affected file silcd/idlist.[ch].
4195 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4196 to use internally the SilcHashTable. The new ID Cache is a lot
4197 faster than the old one. Some of the ID Cache interface was also
4198 rewritten and obsolete and stupid functions were removed.
4200 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Added entry_count field to the SilcHashTable to keep the number
4203 of the entries in the table. Implemented the function
4204 silc_hash_table_rehash. Added new function
4205 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4207 Fixed a minor bug in silc_hash_table_free.
4209 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4210 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4211 into the lib/silcutil/silcutil.[ch].
4213 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Implemented a collision resistant hash table into the
4216 lib/silcutil/silchashtable[ch]. See the header and the source
4217 for the SilcHashTable API.
4219 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Merged dotconf version 1.0.2 into lib/dotconf.
4223 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Do not compile anything in lib/silcsim/* if the SIM support
4226 is not enabled. The tree should now compile without problems
4229 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Compiled the SILC under cygwin. Compiled and tested briefly
4232 without problems. More tests needed. The SIMs didn't compile
4235 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4237 * Fixed possible crash in silc_get_username in the
4238 lib/silcutil/silcutil.c.
4240 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Fixed a va_arg in silc/client_ops.c.
4244 * Oops, RC5 routines were named AES and caused some problems
4245 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4247 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Added new SilcIDIP structure into the lib/silccore/id.h and
4250 replaced the old `ip' fields from all SILC ID's to that type.
4251 This is a step towards IPv6 support.
4253 The silc_id_get_len takes now the ID as an extra argument.
4254 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4255 both IPv4 and IPv6 based ID's.
4257 The affected files are lib/silccore/id.[ch] and other files
4258 around the tree using these routines.
4260 * Removed the ID length arguments in server from various
4261 silc_server_send_notify_* routines -> they are not needed
4264 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Fixed memory leak in silc_encode_pem_file in the file
4267 lib/silcutil/silcutil.c.
4269 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Check minor version as well in the SKE. Affected files are
4272 silcd/protocol.c and lib/silcclient/protocol.c.
4274 * Added --identifier option to the server so that an identifier
4275 can be when creating the public key for the server. Affected
4276 file is silcd/silcd.c.
4278 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4279 lib/silccrypt/silcpkcs.c.
4281 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Register default ciphers and stuff when using -C option with
4284 the server. Affected file sildc/silcd.c.
4286 * Put back the servers public key filename format, it is better
4287 than the new one. For now, the client keys are saved with the
4288 new filename format. The affected file silc/client_ops.c.
4290 * Implemented the Cipher API for the rest of the ciphers that
4291 did not implement it or implemented it the wrong way.
4293 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Register default ciphers and stuff when using the -S option
4296 in the client. Affected file silc/silc.c. Same also when
4297 creating new key pair with -C option.
4299 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Fixed the silc_verify_public_key client operation function to
4302 save the public keys differently. The fingerprint is now
4303 used as filename and not the hostname. This way also the
4304 client keys are saved uniquely and not with hostnames. The
4305 affected file is silc/client_ops.c.
4307 * Trimmed the silc_hash_fingerprint function to remove extra
4308 whitespaces from the end of the fingerprint. The affected
4309 file is lib/silccrypt/silchash.c.
4313 * Added silc_cipher_register_default function to register all
4314 default ciphers. It can be used when configuration files
4315 does not exist and the application does not want any specific
4316 ciphers in any specific order.
4318 The SilcDList is now used as silc_cipher_list dynamically
4319 allocated cipher list. Removed the static list all together
4320 and now all ciphers must be allocated to the dynamic list.
4321 The silc_cipher_alloc routine was changed to check only the
4324 All silc_cipher_* routines that used to return int returns
4327 The affected files lib/silccrypt/silccrypt.[ch].
4329 * The same thing was done to silc_hash_* as for silc_cipher_*
4330 routines. Affected files lib/silccrypt/silchash.[ch].
4332 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4333 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4334 Added also silc_pkcs_[un]register[_default] functions.
4335 Removed the data_context from the PKCS API.
4337 * Added silc_hmac_register_default function to register default
4338 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4339 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4340 to unregister all hmacs at once.
4342 * Register the default ciphers, hash functions, PKCSs and HMACs
4343 if client's configuration file does not exist. The affected
4346 * The client did not load the hash functions from the SIM
4347 modules at all. Added support for this. Affected file is
4348 silc/clientconfig.c.
4350 * When decoding public key with silc_pkcs_public_key_decode, check
4351 the supported algorithm only if PKCS are registered. Affected
4352 file lib/silccrypt/silcpkcs.c. The same was done with the
4353 silc_pkcs_private_key_decode.
4355 * Fixed the SILC List routines to keep the list always in order.
4356 It used to change the list's order when traversing the list but
4357 not it preserves the order. Affected file lib/trq/silclist.h.
4359 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Added the client library to use the SilcSocketConnection's
4362 reference counter (by silc_socket_dup) to prevent the bug that
4363 the socket object may be freed underneath async operation.
4365 * The name resolv library checking fixes in the configure.in.pre.
4368 * Created new version of the protocol drafts for future
4369 development. The -03 drafts are the ones that will be changed
4370 in the trunk now and the -02 will remain as they are.
4372 * Send list of CUMODE notifys to the router when announcing
4373 the channel users to the router. Affected file silcd/server.c.
4374 If the router receiving channel founder CUMODE for a channel
4375 that already has channel founder it will send CUMODE notify
4376 to the sender to remove the channel founder rights from the
4377 announced client. Affected file silcd/packet_receive.c.
4379 * The CUMODE notify may now use Server ID as well as the entity
4380 who changes the mode. Updated protocool specs.
4382 * Updated INSTALL and README files.
4384 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * New web pages in the http://silc.pspt.fi. The pages was
4391 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Implemented the [DenyConnectin] config section in the server.
4394 Added silc_server_config_denied_conn to check whether incoming
4395 connection is denied. Affected file silcd/serverconfig.[ch].
4397 * Do not check the ports when checking the incoming configuration
4398 data if the port is 0, meaning any. Affected file is
4399 silcd/serverconfig.c.
4401 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Fixed buffer overflow in silc_string_compare in the file
4404 lib/silcutil/silcutil.c.
4406 * Fixed double free in silc_server_command_leave in the file
4409 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Fixed the version checking in the server. Affected file is
4414 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Fixed the configuration data fetching when accepting new
4417 connections in the server. Affected file silcd/server.c.
4419 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Added `sender_entry' argument to the function
4422 silc_server_packet_relay_to_channel so that we can check
4423 whether some destination actually belongs to the same route
4424 the sender belongs (ie, we must not resend the packet to the
4425 sender). Affected file silcd/packet_send.[ch].
4427 * Added `servername' field to the SilcClientEntry in the server
4428 to hold the name of the server where client is from. Affected
4429 file is silcd/idlist.h.
4431 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Moved the channel message encrypting in the router betwen
4434 router connections from silc_server_channel_message to the
4435 silc_server_packet_relay_to_channel since we want to check
4436 whether we have anybody channel before encrypting anything.
4437 Affected files silcd/packet_[receive/send].c.
4439 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Fixed the [AdminConnection] server config section to support
4442 multiple entries. Affected file silcd/serverconfig.c.
4444 * Added support into the server to check the validity of the
4445 incoming connection before executing any KE or authentication
4448 * The connection configuration is now saved to the KE and
4449 connection auth protocol contexts and not fetched anymore in
4450 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4452 * The local hosts listenning address and port is also resolved
4453 now when starting the server. We want to have the socket object
4454 to include the real address and port for the listener. Added
4455 new function silc_net_check_local_by_sock into the files
4456 lib/silcutil/silcnet.[ch].
4458 * Fixed a broadcast bug in server -> do not broadcast if we
4461 * Fixed a routing bug. Do not route broadcast packets ever.
4462 Broadcast packets must be processed always and not routed since
4463 they may be destined to some other host than yourself and thus
4464 would get routed without no good reason. Affected file is
4467 * Added function silc_server_config_is_primary_route to check
4468 whether primary router connection has been configured (a router
4469 configuration that we are initiating). If there is not, we
4470 will assume that there is only two routers in the SILC network
4471 and we will use the incoming router connection as our primary
4472 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4474 * Changed the order of the broadcasting. Broadcast _after_ the
4475 packet has been processed not before. Affected file is
4478 * Fixed a [ClientConnection] parsing bug. The port was never
4479 parsed correctly thus resulting to port 0. Affected file
4480 silcd/serverconfig.c.
4482 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4483 argument and did not set the broadcast packet flag. Affected
4484 file silcd/packet_send.c. Fixed same bug in the function
4485 silc_server_send_notify as well.
4487 * If we receive NEW_ID packet for our own ID in the server, ignore
4490 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Removed the nickname from the Private Message Payload.
4495 Updated the code and the protocol specs.
4497 * Updated protocol specs for submitting to the IETF.
4499 * Tweaked the Random Number Generator a bit. Affected file
4500 lib/silccrypt/silcrng.c. Exported a new function
4501 silc_rng_[global]_add_noise which can be used to add more
4504 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Do not parse packets with different timeout when protocol
4507 is active -> may cause problem with rekey. Affected file
4510 * When server receives signoff notify it must not create
4511 new channel key if the client is on any channels since the
4512 sender of the signoff notify will create it.
4514 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Added printing of error messages during SKE protocol from the
4517 failure packet sent by server during SKE. Affected file
4520 * Removed the client's failure_callback handling with timeout
4521 and handle it immediately when received.
4523 * The SKE library returned wrong type in SUCCESS and FAILURE
4524 packets. They must be 32 bit MSB not 16 bit MSB.
4526 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Ok, rewrote the logic of the re-key and now it seems to work.
4529 I tested it on high traffic with frequent re-keys without
4530 problems. Added hmac_receive (and renamed hmac to hmac_send)
4531 in SilcClientConnection in lib/silcclient/client.h and
4532 in SilcIDListData in silcd/idlist.h. Also, removed the
4533 SilcPacketParserContext's cipher and hmac fields as they are
4534 not needed anymore and actually caused some problems when
4535 the ciphers and hmac's changed underneath the packet parser.
4537 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * If re-key protocol is active then process the incoming packets
4540 synchronously since we must assure that icoming packets encrypted
4541 with the old key is processed before the new keys is set to
4542 use. This is true other packets than for REKEY packets.
4543 Affected file silcd/server.c. The same was done to client library
4544 as well, affected file lib/silcclient/client.c.
4546 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Fixed bug in client and server to accept the force send if
4549 the packet is send from silc_[server/client]_packet_process
4550 function. Otherwise the packets are never delivered, oops.
4552 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Disable force sending of packets when REKEY protocol is active.
4555 We must assure that no packet is sent directly when rekey is
4556 performed. All packets must be sent through packet queue.
4557 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4558 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4559 function is silc_[server/client]_packet_send_real to check
4562 * Replaced the SIM paths from example config files to
4563 /usr/local/modules. Also, make install creates now
4564 /usr/local/silc/logs directory to hold all the SILC server
4567 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Made the configure.in.pre work on Solaris. Patch by salo.
4571 * Made all ciphers compatible with non-x86 machines. Defined
4572 CBC mode macros into lib/silccrypt/ciphers_def.h.
4574 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Fixed the make install.
4578 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * When MAC computation fails the silc_packet_decrypt returned 0
4581 even though it was supposed to return -1. Fixed this. The
4582 affected file is lib/silccore/silcpacket.c.
4584 * Do not replace the config files in /etc/silc (in make install)
4585 if they already exist. Affected file ./Makefile.am.
4587 * Do not send re-key packets immediately but through packet queue.
4588 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4590 * Changed silc_net_check_host_by_sock to return FALSE if the
4591 IP/DNS could not be resolved. Though, it returns the IP address
4592 now even if it could not resolve it (but returns also FALSE).
4593 Affected file lib/silcutil/silcnet.[ch].
4595 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added silc_pkcs_decode_identifier to decode the public key's
4598 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4599 Added also silc_pkcs_free_identifier. Added also new context
4600 SilcPublicKeyIdentifier.
4602 * Added -S option to the silc client. It is used to dump the
4603 contents of the specified public key file.
4605 * Changed the PKCS api to return the public key length when
4606 setting the public key.
4608 * Fixed a fatal bug in the public and private key file loading.
4609 Affected file lib/silccrypt/silcpkcs.c.
4611 * Execute the packet parsing for client with zero (0) timeout
4612 if the protocol is active. Affected file silcd/server.c.
4614 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Made the key generation options to the silcd program. Added
4617 -C option, equivalent to client's option.
4619 * Added new [ServerKeys] config section to the server. It
4620 configures the server's public and private key.
4622 * Defined generic Public Key Payload into the protocol
4623 specification to send specific type of public keys and
4626 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4627 public key or certificate.
4629 * Implemented the GETKEY command to the server and to the
4630 client library and on user interface.
4632 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Made preliminary `make install' work.

4663 SilcClientConnection structure; not needed. Affected file is
4664 lib/silcclient/client.h.
4668 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Do not ask whether user wants to use the negotiated private key
4671 for private messages, just use it. Affected file is
4672 silc/local_command.c.
4674 * Added `send_enc_key' and `enc_key_len' fields to the
4675 SilcIDListData structure since they are needed in the re-key
4676 phase. Affected file is silcd/idlist.[ch].
4678 * Implemented the simple re-key protocol into the server.

4690 the PFS is to be performed in the re-key. Affected file is
4693 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4696 int64 of at least the xintXX size. If void * is less that 4
4697 bytes uint32 * will be used. Defined bool as boolean.
4699 * Changed _ALL_ unsigned long and unsigned int to uint32,
4700 unsgined short to uint16 in the source tree.
4702 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4703 not handle clients that has entry->data.registered == FALSE.
4704 They are not in the network anymore. Affected file is
4707 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Implemented the sending of the SERVER_SIGNOFF notify in the
4710 server. Affected file is silcd/server.c.
4712 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

4721 implemnted the printing of the SERVER_SIGNOFF info to the
4722 application. Affected file silc/client_ops.c.
4724 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4725 if the deleting was successful. Affected file silcd/idlist.[ch].
4727 * Added support for public key authentication in the connection
4728 authentication protocol in the client library. Affected file
4729 lib/silcclient/protocol.c.
4731 * Changed the server's silc_idlist_get_clients_by_* interface
4732 to support already allocated array so that new entries may be
4733 added to pre-allocated array. Affected file silcd/idlist.[ch].
4734 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4735 and command replies.
4737 * All command reply functions in the server now calls the
4738 pending command callback even if error occured. This way the
4739 error will be delivered to the client as well. Affected files
4740 silcd/command.c and silcd/command_reply.c.
4742 * Fixed INFO command to return local server's info if no server
4743 was provided. Affected file lib/silcclient/command.c.

4757 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Added channel key re-key support. The re-key is perfomed
4762 only by the router and is done once in an hour. Added `rekey'
4763 field to the SilcChannelEntry in the server. Affected files
4764 silcd/server.c and silcd/idlist.h.
4766 * Added silc_task_unregister_by_context into the file
4767 lib/silcutil/silctask.[ch].
4769 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Added SILC_UMODE_GONE mode to indicate when the client is not
4772 present in the SILC network. Added also support to the local
4773 command AWAY that will set this mode. Added support of showing
4774 "xxx is gone" in WHOIS command. The USERS command shows the
4775 gone status as well.
4777 * Fixed setting server and router operator privileges in the
4778 server's UMODE command. Affected file silcd/command.c.
4780 * Merged the SKE KE1 and KE2 payloads into one payload. The
4781 new KE payload is equivalent to the old KE2 payload.
4783 Cleaned up the SKE Start Payload parsing. It now uses the
4784 simple buffer unformatting to do the parsing. A lot faster
4787 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4788 to the SKE that is used to indicate whether both of the SKE
4789 parties should perform authentication. By default only the
4790 responder performs authentication. By setting this flag also
4791 the initiator must do authentication. By default it is unset
4792 since in normal SKE case, client to server connection, only
4793 the responder should do authentication. When doing SKE between
4794 two clients both should perform authentication. Updated the
4795 code and the protocol specs.
4797 * A little fix to IDENTIFY command in the server. Search the
4798 client first by hash not nickname. Affected file is
4801 * Fixed the silc_client_close_connection to support closing
4802 the client to client connections wihtout deleting too much
4803 data. Affected file lib/silcclient/client.c.
4805 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4806 are received if protocol used to be active but is not anymore
4807 the application would crash due to NULL pointer dereference.
4808 Affected files silcd/server.c and lib/silcclient/client.c.
4810 * Added `hash' field to the SilcClientConnection to include
4811 the hash function negotiated in the SKE protocol.
4813 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4814 to set the channel founder authentication data. A client can
4815 claim the founder rights later by providing the authentication
4816 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4817 This way the channel founder can regain the channel founder
4818 privileges even it is left the channel. This works only on
4819 local server and the client must be connected to the same
4820 server to be able to regain the founder rights. Updated the
4821 protocol specs accordingly.
4823 Added support to the CMODE command in the client to set the
4824 founder auth data. Read the README to see how to set it.
4826 Added support to the CUMODE command to claim the founder
4827 rights. Read the README to see how to do it.
4829 Added support for the founder authentication to the Channel
4830 Entry in the server. Affected file silcd/idlist.h.
4832 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4833 server's CMODE command. Affected file silcd/command.c.
4835 * Added the following new functions into lib/silccore/silcauth.[ch]:
4836 silc_auth_get_method and silc_auth_get_data.
4838 * The server now saves the remote hosts public key to the
4839 SilcIDListData pointer. Affected file silcd/protocol.c.
4841 * The normal server now does not remove the channel entry from
4842 the cache if the founder authentication data is set. It used
4843 to remove it if the founder was the last one on the channel on
4844 the server and left the channel. The auth data is saved and
4845 if the channel is re-joined later the old entry is used with
4846 the old auth data. Affected files silcd/command_reply.c and
4849 * Removed the `pkcs' field from the SilcIDListData structure
4850 in the server; it is not used. Affected file silcd/idlist.h.
4852 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Fixed packet processing on slow links. Partial packets were
4855 never re-processed because the incoming data buffer was cleared
4856 by the application. Application must not directly clear the
4857 sock->inbuf, the packet processing routines handle it. Fixed
4858 this in client library and in server.
4860 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Fixed the WHOIS and IDENTIFY send reply function to really
4863 check whether to send list or just one entry. Affected file
4866 * Cleaned up the LEAVE command's channel key distribution. The
4867 affected file silcd/command.c.
4869 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4870 can enforce the channel mode as well. In that case the ID
4871 includes the ID of the server. The code now enforces the
4872 mode change if the router have different mode than the server.
4874 * The notify client operation with CMODE_CHANGE notify can now
4875 return NULL client_entry pointer if the CMODE was not changed
4876 by client. Application must check for this.
4878 * Added <Server ID> argument to INFO command to support server
4879 info fetching by Server ID.
4881 * Added silc_server_announce_get_channel_users to get assembled
4882 packets of channel users of the specified channel. Affected
4883 file silcd/server.[ch].
4885 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4886 was freed underneath the ID Cache.
4888 * Re-announce clients when the server received CHANNEL_CHANGE
4889 notify from the router. Affected file silcd/packet_send.c.
4891 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4894 crashed since it did not handle the fact that there is no cipher
4895 called "3" and didn't check the error condition. Now fixed.
4897 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4898 flag. It can be used to send message requests.
4900 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Implemented the RESTART command in the client.
4904 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4905 notice type messages. Added notice printing to the user
4908 * The channel keys are not re-generated if the channel's mode
4909 is PRIVKEY, ie private key on the channel exists. Affected
4910 files silcd/server.c and silcd/command.c.
4912 * Fixed a little bug in channel message delivery when channel
4913 private keys are set in the server. Affected file is
4914 silcd/packet_send.c.
4916 * Changed the setting on channel->on_channel = TRUE from the
4917 silc_client_save_channel_key to the JOIN command reply. The
4918 key payload is not received if the private channel key is set.
4919 Affected file lib/silcclient/command_reply.c and the
4920 lib/silcclient/client_channel.c.
4922 * When the CMODE_CHANGE notify is sent and the channel private
4923 key mode is removed the channel key must be re-generated in
4924 other cells as well. Added this support for the router in the
4925 silcd/packet_receive.c.
4927 * Added new local command NOTICE to send notice message on
4928 channel. Affected file silc/local_command.[ch].
4930 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Added new local command ME to the client. It is used to send
4933 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4934 some action. Affected file silc/local_command.[ch].
4936 * Changed channel_message and private_message client operations
4937 to deliver the message flags to the application. Added also
4938 the `flags' arguments to the silc_client_send_channel_message
4939 and silc_client_send_private_message functions. Affected file
4942 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Redefined the Private Message Payload to support private message
4945 keys and to support the new private message flags. Updated
4946 the protocol specs. Flags makes it possible to have for example
4947 CTCP style messages.
4949 * Added new type SilcPrivateMessagePayload and defined an API
4950 for it in the lib/silcclient/silcprivate.[ch].
4952 * Tested private message private keys successfully. Tested the
4953 private message key set, unset and list commands with the new
4956 * Redefined the Channel Message Payload to include the channel
4957 message flags (equal with private message flags) to support
4958 for example CTCP style messages.
4960 * Defined some of the message (for channel and private message)
4961 flags. Updated the protocol specs and added the flags to the
4962 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4964 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Added SilcKeyAgreementStatus type to the key agreement routines
4967 to indicate the current status and error if one occured.
4968 The status types are defined in the lib/silcclient/silcapi.h.
4970 * Added new local command KEY that is used to set and unset private
4971 keys for channels, set and unset private keys for private messages
4972 with remote clients and to send key agreement requests and
4973 negotiate the key agreement protocol with remote client. The
4974 key agreement is supported only to negotiate private message keys,
4975 it currently cannot be used to negotiate private keys for channels,
4976 as it is not convenient for that purpose.
4978 * Fixed a minor pending callback setting bug in the function
4979 silc_client_get_client_by_id_resolve, now the function works.
4980 Affected file lib/silcclient/idlist.c.
4982 * Added function silc_net_get_local_port to get local bound
4983 port by socket. Added to lib/silcutil/silcnet.[ch].
4985 * Added `sockets' and `sockets_count' fields to the SilcClient
4986 object. They hold the sockets of the listenning sockets in
4987 the client. Listenning sockets may be for example the key
4988 agreement server. Affected file lib/silcclient/client.[ch].
4989 Added functions the silc_client_add_socket and the
4990 silc_client_del_socket. They are exported to the application
4993 * Added ~./silc/clientkeys to support other client's public keys.
4995 * Renamed verify_server_key client operation to verify_public_key
4996 and added one argument to indicate the type of the connection
4997 (server, client etc.).
4999 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added silc_server_connection_auth_request to handle the
5002 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5003 silcd/packet_receive.[ch].
5005 * Added silc_server_send_connection_auth_request into the
5006 silcd/packet_send.c to send the connection auth request packet.
5008 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5011 * Fixed the public key authentication in responder side in the
5012 server. The `auth_data' pointer includes the SilcPublicKey
5013 not the path to the public key. Affected file silcd/protocol.c.
5015 * Implemented the public key authentication in the initiator side
5016 in the server. Affected file silcd/protocol.c.
5018 * Removed the [RedirectClient] config section from the server
5019 configuration. Is not needed and I don't want to implement it.
5021 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Cleaned up the CMODE command in the server. It now works
5024 correctly and supports all the modes defined in the protocol.
5025 Affected file is silcd/command.c.
5027 * Added `hmac_name' field to the SilcChannelEntry in the server
5028 to hold the default HMAC of the channel. It can be set when
5029 creating the channel (with JOIN command). Affected files
5032 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5033 type to indicate the change of the current cipher and hmac
5034 on the channel. Client can safely ignore the <cipher> argument
5035 (if it chooses to do so) since the CHANNEL_KEY packet will
5036 force the channel key change anyway. The <hmac> argument is
5037 important since the client is responsible of setting the new
5038 HMAC and the hmac key into use.
5040 * Fixed the CMODE command in the client library as well.
5042 * Tested CMODE command in router environment successfully.
5044 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Show the version of the remote client (or server) when connecting
5047 to the server. It is logged to the log file. Affected file
5048 is silcd/protocol.c.
5050 * Fixed the KILLED notify handling in the client library. The
5051 client must be removed from all channels when receiving the
5054 Also, do not remove the client entry when giving the KILL
5055 command but when the KILLED notify is received.
5057 * Removed silc_idlist_find_client_by_nickname from the server.
5058 Not needed anymore. Affected files silcd/idlist.[ch].
5060 * Implemented the CHANNEL_CHANGE notify type handling to the
5061 server. Affected file silcd/server.c.
5065 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added silc_server_send_notify_invite to send the INVITE
5068 notify between routers.

5079 * Added function silc_server_get_client_resolve to find the
5080 client entry by ID from all ID lists and then resolve it
5081 (using WHOIS) if it cannot be found. Affected file is
5084 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Implemented the BAN command to the client library.
5088 * The JOIN command in the server now checks the invite list
5091 * Changed the silc_command_reply_payload_encode_va and the
5092 silc_command_payload_encode_va to support that if argument is
5093 NULL it ignores and checks the next argument. Affected file
5094 lib/silccore/silccommand.c.
5096 * Added silc_server_send_notify_ban to send the BAN notify
5097 type between routers.
5099 * Chaned the silc_notify_payload_encode to support that if
5100 argument is NULL it ignores and checks the next argument.
5101 Affected file lib/silccore/silcnotify.c.
5103 * Tested ban lists in router environment successfully.
5105 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Implemented BAN command to the server, in silcd/command.[ch].
5109 * Removed the BAN and INVITE_LIST modes from the CMODE command
5112 * Added function silc_string_match to regex match two strings.
5113 Affected files lib/silcutil/silcutil.[ch].
5115 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Redefined parts of the SilcChannelEntry in the server to support
5118 the new ban and invite lists.
5120 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Redefined the INVITE command. The same command can be used to
5123 invite individuals to the channel but also to manage the invite
5124 list of the channel (to add to and remove from the invite list).
5125 Updated the protocol specs.
5127 * Added new command SILC_COMMAND_BAN that can be used to manage
5128 the ban list of the channel. Updated the protocol specs.
5130 * Removed the channel modes: the SILC_CMODE_BAN and the
5131 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5132 in the CMODE command. The equivalent features are now available
5133 using INVITE and BAN commands. Updated the protocol specs.
5135 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5136 in the network about change in the current ban list. The notify
5137 type is not used by the client.
5139 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5140 support the invite lists.
5142 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added new function silc_string_regexify that converts string
5145 including wildcard characters into regex string that can
5146 be used by the GNU regex library. Added into the file
5147 lib/silcutil/silcutil.[ch].
5149 Added silc_string_regex_combine to combine to regex strings
5150 into one so that they can be used as one regex string by
5151 the GNU regex library. Added into the file
5152 lib/silcutil/silcutil.[ch].
5154 Added silc_string_regex_match to match two strings. It returns
5155 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5157 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Imported GNU regex to the soruce tree into lib/contrib.
5160 Fixed some compiler warning from the regex.c.
5162 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5167 the server argument in the command.
5169 * Added `nickname_len' argument to the silc_idlist_add_client
5170 in the server, as the `nickname' argument may be binary data
5173 * Added silc_idlist_get_channels to return all channels from
5176 * Implemented LIST command to the server. Affected file is
5179 * Implemented the LIST command to the client library and on the
5182 * Added [<user count>] argument to the LIST command reply.
5183 With private channels the user count is not shown.
5185 * Updated TODO and README.
5187 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * The client entry's data.registered must be TRUE even with
5190 global client entry on global client list. The data.registered
5191 is used to check whether the client is anymore in the network,
5192 for example with WHOWAS command so it must be valid.
5194 * Fixed the WHOWAS command in the server. It now actually works
5195 in router environment. Added function into silcd/command_reply.c
5196 silc_server_command_reply_whowas_save.
5198 * Added silc_idlist_purge function to the silcd/idlist.c
5199 to periodically purge the ID Cache.

5209 they were buggy because of the WHOWAS information.
5211 * Fixed local command MSG to handle the async resolving of
5212 the remote client properly. It used to fail the first MSG.
5213 Affected file silc/local_command.c.
5215 * Added `data_len' field to SilcIDCache context.
5217 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * Update TODO. Todo in commands in the server.

5224 used by routers as broadcast packet to inform other routers
5225 about the changed user mode.
5227 Implemented the notify handling in the server. Affected file is
5228 silcd/packet_receive.c. Added the function
5229 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5231 * Added new generic Channel Payload and deprecated the New Channel
5232 Payload. The New Channel Payload is now the generic Channel
5235 * Added new argument `mode' to the silc_server_send_new_channel
5236 as it is required in the Channel Payload now.
5238 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5239 and created a new and real SilChannelPayload to represent the
5240 new generic Channel Payload. Implemented the encode/decode
5241 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5243 * Added silc_server_get_client_channel_list to return the list
5244 of channels the client has joined for WHOIS command reply.
5245 Affected file silcd/server.[ch].
5247 * Implemented the channel list sending in the WHOIS command reply
5248 in server and in the client.
5250 Implemented the channel list displaying on the user interface
5251 as well. Affected file silc/client_ops.c.
5253 * Added silc_channel_payload_parse_list to parse list of Channel
5254 Payloads. It returns SilcDList list of SilcChannelPayloads.
5255 Client for example can use this function to parse the list of
5256 channels it receives in the WHOIS command reply. The caller
5257 must free the list by calling silc_channel_payload_list_free.
5258 Affected files lib/silccore/silcchannel.[ch].
5260 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Added one new argument <user mode> to the WHOIS command reply
5263 to return the mode of the user in SILC. Updated the protocol

5279 unknown command. Affected file silcd/command.c.
5281 * All server commands now handle the command identifier the right
5282 way when sending the command reply to the client. The client can
5283 use to identify the command replies with the identifier.
5285 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Added silc_server_get_client_route to resolve the route to
5288 the client indicated by the client ID. Affected file is
5291 * Added silc_server_relay_packet as general function to relay
5292 packet to arbitrary destination. This deprecates functions
5293 like _send_private_message_key, _relay_notify etc. Affected
5294 file is silcd/packet_send.[ch].
5296 Removed silc_server_send_key_agreement,
5297 silc_server_send_private_message_key and
5298 silc_server_packet_relay_notify functions from the file
5299 silcd/packet_send.[ch].
5303 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5304 server. Affected file silcd/packet_receive.[ch].
5306 * Implemented the KILL command to the client. Implemented the
5307 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5308 Affected files lib/silcclient/command[_reply].c and
5309 lib/silcclient/client_notify.c. Implemented the KILL notify
5310 printing in the user inteface.
5312 * Fixed a lot silc_parse_nick memory leaks from the client
5313 library in the file lib/silcclient/command.c.
5315 * Changed the silc_server_send_notify_on_channels's `sender'
5316 argument from SilcSocketConnection to SilcClientEntry to
5317 check the sender as entry and not as connection object and not
5318 to send to the client provided as argument. The affected file
5319 is silcd/packet_send.[ch].
5321 * The notify packets that are destined directly to the client used
5322 to not to be processed by the server. Now changed that and the
5323 server processes all notify packets. After relaying the packet
5324 to the client the notify packet is processed in the server.
5326 * The silc_server_free_client_data now checks whether there is
5327 pending outgoing traffic for the client and purges the data to
5328 the network before removing the client entry.
5330 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5333 an client is killed from the SILC Network. Updated the protocol
5336 Added new function silc_server_send_notify_killed to the
5337 silcd/packet_send.[ch].
5339 * Added function silc_server_packet_relay_notify to relay notify
5340 packets that are destined directly to a client. In this case
5341 the server does not process the notify packets but merely relays
5342 it to the client. Affected file silcd/packet_send.[ch].
5344 Added also silc_server_packet_process_relay_notify to check
5345 whereto relay the notify. Affected file is
5346 silcd/packet_receive.[ch].
5348 * Implemented the KILL command to the server.
5352 * Added the backup schema desgined last fall to the protocol
5353 specs for everyone to see. The specification is in the
5354 *-spec-xx.txt draft and the packet type definitions for the
5355 backup routers is in *-pp-xx.txt draft. Thusly, added also
5356 new packet type SILC_PACKET_CELL_ROUTERS.
5358 * A big security problem in the implementation discovered. The
5359 signoff of an client did not cause new channel key generation
5360 which it of course should've done. The channel keys must be
5361 always re-generated when client leaves (or signoffs) the channel.
5362 The silc_server_remove_from_channels funtion now handles
5363 the channel key re-generation.
5365 * Added `sender' argument to the silc_server_send_notify_on_channels
5366 to not to send the client provided as argument. Affected file
5367 silcd/packet_send.[ch].
5369 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Implemented OPER and SILCOPER commands into the server and
5374 * Added silc_auth_verify and silc_auth_verify_data to verify
5375 the authentication directly from the authentication payload.
5376 It supports verifying both passphrase and public key based
5377 authentication. Affected file lib/silccore/silcauth.[ch].
5379 * Added `hash' field to the SilcIDListData structure. It is the
5380 hash negotiated in the SKE protocol. Affected file is
5383 * Slight redesigning of the SilcAuthPayload handling routines.
5384 Do not send SilcPKCS but SilcPublicKey as argument.
5386 * Implemented the public key authentication support to the
5387 serverconfig. The public key is loaded from the provided path
5388 and saved as authentication data to void * pointer. Thus,
5389 changed the unsigned char *auth_data to void *auth_data;
5391 * Fixed SHUTDOWN command to send the reply before the server
5392 is shutdown. :) Affected file silcd/command.c.
5394 * Fixed fatal bug in CONNECT command. The hostname was invalid
5395 memory and server crashed. Affected file silcd/command.c.
5397 * Fixed fatal bug in CLOSE command. The server_entry became
5398 invalid but was referenced later in the command. Affected file
5401 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Fixed fatal bug in failure packet handling. Server ignored
5404 the failure and thus crashed when it came.
5408 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5411 that the command may be executed only once in (about) 2 seconds.
5412 The old SILC_CF_LAG flag is same but allows command bursts up
5413 to five before limiting.
5415 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5416 server code. Various commands now includes the CF_LAG_STRICT
5417 flag to disallow any kind of miss-use of the command.
5419 * Fixed the silc_buffer_unformat to not to allocate any data
5420 if the length of the data is zero. It used to allocate the
5421 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5423 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Changed the format of AdminConnection configuration section
5426 in the server. Added username of the admin to the format.
5427 Affected files silcd/serverconfig.[ch].
5429 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5430 to return admin configuration data by host, username and/or
5433 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Implemented WHOWAS command to the server. Added the functions:
5437 silc_server_command_whowas_parse,
5438 silc_server_command_whowas_send_reply,
5439 silc_server_command_whowas_from_client and
5440 silc_server_command_whowas_from_server
5442 * Added <Client ID> argument to the WHOWAS command reply. Updated
5443 the protocol specs accordingly.
5445 * Implemented WHOWAS command and command_reply to the client
5448 Implemented the WHOWAS printing on the user interface.
5450 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added new argument to the WHOWAS command reply, the real name.
5453 It is an optional argument. Updated the protocol specs.
5455 * Added SilcIDCacheDestructor callback that is registered when
5456 the SilcIDCache is allocated. The callback is called when
5457 an cache entry in the ID Cache expires, or is purged from the
5458 cache. Added into lib/silccore/idcache.[ch].
5460 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5461 to destruct the client entries when the cache entry expires.
5462 Other ID Cache's in server and in the client library ignores
5465 * If the ID Cache entry's `expire' field is zero then the entry
5466 never expires. Added boolean `expire' argument to the
5467 silc_idcache_add function in the lib/silccore/idcache.[ch].
5468 If it is TRUE the default expiry value is used.
5470 * Added silc_server_free_client_data_timeout that is registered
5471 when client disconnects. By default for 5 minutes we preserve
5472 the client entry for history - for WHOWAS command.
5474 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Added support to the server to enforce that commands are not
5477 executed more than once in 2 seconds. If server receives
5478 commands from client more frequently, timeout is registered
5479 to process the commands. Affected file silcd/command.c.
5480 Added new function silc_server_command_process_timeout.
5482 * Changed NICK_NOTIFY handling in client library to check that
5483 if the client's nickname was changed, so there is no need to
5484 resolve anything from the server.
5486 * Removed error printing from the WHOIS and IDENTIFY commands.
5487 If error occurs then it is ignored silently in the client library.
5488 The application, however, may map the received error to
5489 human readable error string. The application currently maps
5490 the NO_SUCH_NICKNAME error to string.
5492 * Made the command status message public to the application. Moved
5493 them from lib/silcclient/command_reply.c to
5494 lib/silcclient/command_reply.h. The application can map the
5495 received command status to the string with the
5496 silc_client_command_status_message function.
5498 * Added check to the server to check that client's ID is same
5499 as the Source ID in the packet the client sent. They must
5502 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Added dist-bzip hook to the Makefile.am to make bzip2
5505 compressed distributions.
5507 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Server now enforces the maximum length for the nickname and
5510 the channel as protocol specification dictates. 128 bytes for
5511 nickname and 256 bytes for channel name.
5513 * Moved the WHOIS printing to the application. The client libary
5514 does not print out the WHOIS information anymore, the application
5515 must do it. Renamed silc_client_command_reply_whois_print to
5516 the silc_client_command_reply_whois_save.
5518 The client's idle time is also sent to the application now, and
5519 the idle is shown on screen.
5521 * Added silc_client_command_reply_identify_save to save the
5522 received IDENTIFY entries.
5524 * Do not check for channel private keys in message sending and
5525 reception if the channel does not have the PRIVKEY mode set.
5526 Affected file lib/silclient/client_channel.c.
5528 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5531 just surfaced after chaning the JOIN procedure.
5533 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added silc_client_get_clients_by_list to get client entries
5536 from Client ID list, that is returned for example by JOIN
5537 and USERS command replies. The application should use this
5538 function for example when JOIN command reply is received to
5539 resolve the clients already on the channel (library does not
5540 do that anymore as USERS command reply is not used in the JOIN
5541 procedure anymore). Affected files lib/silcclient/silcapi.h and
5542 lib/silcclient/idlist.c.
5544 * JOIN command reply and USERS command reply returns now SilcBuffer
5545 pointers instead of unsigned char pointers when returning
5546 the client list and mode list.
5548 * Added <Client ID> argument to the JOIN command reply, mainly
5549 for the server to identify for which client the command was
5550 originally sent. Updated protocol specs accordingly.
5552 * Added SilcDlist private_key pointer to the SilcChannelEntry
5553 in the client to support the channel private keys. Affected
5554 file is lib/silcclient/idlist.h.
5556 * Added SilcChannelPrivateKey argument to the function
5557 silc_client_send_channel_message so that application can choose
5558 to use specific private ke if it wants to. If it is not provided,
5559 the normal channel key is used, unless private keys are set.
5560 In this case the first (key that was added first) is used
5561 as the encryption key.
5563 * Implemented the support for channel private key handling.
5564 Implemented the following functions:
5566 silc_client_add_channel_private_key,
5567 silc_client_del_channel_private_keys,
5568 silc_client_del_channel_private_key,
5569 silc_client_list_channel_private_keys and
5570 silc_client_free_channel_private_keys
5572 Affected file lib/silcclient/client_channel.c.
5574 * Added the support for the private keys in the channel message
5575 sending and encryption and in the message reception and
5576 decryption. Affected funtions are
5577 silc_client_send_channel_message and silc_client_channel_message.
5579 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Added SKE's key verify callback to the client library's
5582 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5584 * Removed the statement that server (or router) must send USERS
5585 command reply when joining to the channel so that the client
5586 knows who are on the channel. Instead, the client list and
5587 client's mode list is now sent in the JOIN command reply to the
5588 client who joined channel. This is better solution.
5590 * Added function silc_server_get_users_on_channel and function
5591 silc_server_save_users_on_channel to the silcd/server.[ch].
5593 * Removed function silc_server_command_send_users from the
5596 * Do not show topic on the client library anymore. The topic is
5597 sent in the command reply notify to the application and the
5598 application must show the topic now.
5600 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added client searching by nickname hash into the IDENTIFY and
5603 WHOIS commands in the server as they were clearly missing from
5604 them. Affected file is silcd/command.c.
5606 * Fixed a bug in private message receiving in the client library.
5607 The remote ID was freed and it wasn't supposed, now it is
5610 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Minor fix to the channel payload; allocate the data area, as it
5613 needs to be of specific length.
5615 * If the key agreement port is zero then the operating
5616 system will define the bound port. Affected files are
5617 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5619 * Added new function silc_channel_payload_decrypt into the file
5620 lib/silccore/silcchannel.[ch].
5622 * Moved the channel message etc, check from silc_packet_decrypt
5623 to applications. The library calls now a generic
5624 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5625 when the packet is either normal or special. This was done to
5626 allow more wide range of checking that was not allowed when
5627 the code was in library. Now applications can do virtually any
5628 checks to the packet and return to the library the decision how
5629 the packet should be processed. Affected files are
5630 lib/silccore/silcpacket.[ch].
5632 Added silc_server_packet_decrypt_check to the server and
5633 silc_client_packet_decrypt_check to the client library.
5635 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5636 to send with specified source and destination information.
5638 * Channel message delivery between routers was broken after the
5639 channel key distribution was fixed earlier. The channel key
5640 was used be to distributed to other routers as well which is not
5641 allowed by the protocol. Now this is fixed and channel keys
5642 really are cell specific and the channel message delivery between
5643 routers comply with the protocol specification.
5645 * Fixed various commands in server to check also the global list
5646 for the channel entry and not just the local list. The affected
5647 file silcd/command.c.
5649 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added assert()s to buffer formatting and unformatting routines
5652 to assert (if --enable-debug) when error occurs. Affected
5653 file: lib/silcutil/silcbuffmt.c.
5655 * Changed to auto-reconnect to check whether the remote host is
5656 router and register the re-connect timeout if it is. It used
5657 to check that whether we are normal server, but router must do
5658 auto-reconnect with another router as well. Affected file
5661 * Removed the [<key len>] option from CMODE command as the cipher
5662 name decides the key length, nowadays. See the defined ciphers
5663 from the protocol specification.
5665 * Added [<hmac>] option to the CMODE command to define the HMAC
5666 for the channel. Added SILC_CMODE_HMAC channel mode.
5668 * Added [<hmac>] option for the JOIN command so that user can
5669 select which HMAC is used to compute the MACs of the channel
5672 * Added Hmac field to the Channel Message Payload. The integrity
5673 of plaintext channel messages are now protected by computing
5674 MAC of the message and attaching the MAC to the payload. The
5675 MAC is encrypted. Now, it is clear that this causes some
5676 overhead to the size of the packet but rationale for this is that
5677 now the receiver can verify whether the channel message decrypted
5678 correctly and also when private keys are set for the channel the
5679 receiver can decrypt the packet with several keys and check from
5680 the MAC which key decrypted the message correctly.
5682 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5683 lib/silccrypt/silccipher.[ch].
5685 * Added silc_hash_len to return the digest length into the
5686 lib/silcrypt/silchash.[ch].
5688 * Rewrote parts of Silc Channel Payload interface in the
5689 lib/silccore/silcchannel.[ch]. The encode function now also
5690 encrypts the packet and parse function decrypts it.
5692 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Fixed a minor formatting bug in the SKE's key material processing.
5695 It actually might have processed the keys wrong way resulting
5698 * Redefined the mandatory HMAC algorithms and added new algorithms.
5699 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5700 and hmac-md5 truncated to 96 bits. The mandatory is now
5701 hmac-sha1-96. Rest are optional (including the one that used
5702 to be mandatory). Rationale for this is that the truncated HMAC
5703 length is sufficient from security point of view and can actually
5704 make the attack against the HMAC harder. Also, the truncated
5705 HMAC causes less overhead to the packets. See the RFC2104 for
5708 * Added new [hmac] configuration section. The SKE used to use
5709 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5710 is of course wrong. The official names that must be proposed in
5711 the SKE are the ones defined in the protocol specification
5712 (hmac-sha1-96 for example). The user can configure any hmac
5713 using any hash function configured in the [hash] section. At
5714 least, the mandatory must be configured.
5716 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5718 * Added HMAC list to the SKE proposal list. It has now both
5719 hash algorithm list and HMAC list. This makes the protocol
5720 incompatible with previous versions. The SKE now seems to work
5721 the way it is supposed to work, for the first time actually.
5723 * Defined plain Hash algorithms to the protocol specification.
5726 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Implemented support for key agreement packets into the server.
5729 Added functions silc_server_key_agreement and
5730 silc_server_send_key_agreement. Other than these functions,
5731 server has nothing to do with this packet.
5733 * Added support for private message key packets into the server.
5734 Added functions silc_server_private_message_key and
5735 silc_server_send_private_message_key.
5739 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5740 called in the protocol's final callback instead in the END
5741 protocol state. This makes a little more sense and in the same
5742 time in client we can use the same protocol routines for normal
5743 key exchange and to key agreement packet handling as well.
5745 * Added to both client's and server's KE protocol context the
5746 SilcSKEKeyMaterial pointer to save the key material. We will
5747 bring the key material to the protocol's final callback by doing
5748 this. The final callback must free the key material.
5750 * Added SKE's packet_send callback into client's KE protocol
5751 context so that the caller can choose what packet sending function
5752 is used. This way we can use different packet sending when
5753 doing normal SKE when doing key agreement packet handling (in
5754 the key agreement packet handling we do not want to encrypt
5757 * Implemented the responder side of the key agreement routines
5758 in the client. The client can now bind to specified port and
5759 accept incoming key negotiation. The key material is passed
5760 to the application after the protocol is over.
5762 * Implemented the processing of incoming Key Agreement packet
5763 in the client. Added function silc_client_key_agreement to
5766 * Implemented the intiator side of the key agreement routines
5767 in the client. The client can now initiate key agreement with
5768 another remote client. The key material is passed to the
5769 application after the protocol is over.
5771 * Created client_keyagr.c to include all the key agreement
5774 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5775 SILC_TASK_CALLBACK except that it is not static.
5777 * Created client_notify.c and moved the Notify packet handling
5778 from the client.[ch] into that file.
5780 * Created client_prvmsg.c and moved all private message and
5781 private message key routines from the client.[ch] into that file.
5783 * Create client_channel.c and moved all channel message and
5784 channel private key routines from the client.[ch] into that file.
5786 * Changed silc_client_get_client_by_id_resolve to resolve with
5787 WHOIS command instead of IDENTIFY command, in the file
5788 lib/silclient/idlist.c.
5790 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Implemented the SKE's responder side to the Client library.
5794 * When FAILURE is received to the protocol do not trust it
5795 blindly. Register a timeout to wait whether the remote closes
5796 the connection as it should do it, only after that process the
5797 actual failure. This was changed to both client and server.
5799 * Added client_internal.h to include some of the structures
5800 there instead of client.h in lib/silcclient/.
5802 * Added function silc_task_unregister_by_callback to unregister
5803 timeouts by the callback function.
5805 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Some "Incomplete WHOIS info" errors has been appearing on the
5808 log files. Took away the entry->userinfo check from WHOIS
5809 reply sending. The entry->userinfo is now " " if client did not
5810 provide one. I thought this was fixed earlier but something
5811 is wrong still. Let's see if the error still appears.
5813 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Fixed a minor bug in the login when the channel key is
5816 re-generated in the server. It used to generate the key in
5817 wrong order and thus caused problems in the channel traffic.
5819 * Fixed a minor bug in channel key distsribution after
5820 KICK command. The key was not sent to the router even though
5823 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Added silc_ske_process_key_material_data as generic routine
5826 to process any key material as the SILC protocol dictates. The
5827 function is used by the actual SKE library but can be used by
5828 applications as well. This relates to the private message keys
5829 and the channel private keys since they must be processed the
5830 same way the normal SILC session keys. The protocol dictates
5831 this. Affected files: lib/silcske/silcske.[ch].
5833 Added also silc_ske_free_key_material to free the
5834 SilcSKEKeyMaterial structure.
5836 * Defined silc_cipher_set_key function to set the key for
5837 cipher without using the object's method function. The affected
5838 files: lib/silccrypt/silccipher.[ch].
5840 * Implemented silc silc_client_add_private_message_key,
5841 silc_client_add_private_message_key_ske,
5842 silc_client_del_private_message_key,
5843 silc_client_list_private_message_keys and
5844 silc_client_free_private_message_keys functions in the
5847 Added functions silc_client_send_private_message_key to send
5848 the Private Message Key payload and silc_client_private_message_key
5849 to handle incoming Private Message Key payload.
5851 * Added Cipher field to the Private Message Key payload to set
5852 the cipher to be used. If ignored, the default cipher defined
5853 in the SILC protocol (aes-256-cbc) is used.
5855 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Removed lib/silcclient/ops.h file.
5859 Redefined parts of the SILC Client Library API. Created new
5860 file silcapi.h that deprecates the ops.h file and defines the
5861 published Client Library API. Defined also private message key
5862 API and channel private key API into the file.
5864 This is the file that the application must include from the
5865 SILC Client Library. Other files need not be included by
5866 the application anymore.
5868 * Added new key_agreement client operation callback and also
5869 defined the Key Agreement library API for the application.
5871 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5874 is used by clients to request key negotiation between another
5875 client in the SILC network. If the negotiation is started it
5876 is performed using the SKE protocol. The result of the
5877 negotiation, the secret key material, can be used for example
5878 as private message key.
5880 Implemented the Key Agreement payload into the files
5881 lib/silccore/silauth.[ch].
5883 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Redefined ciphers for the SILC protocol. Added some new ciphers
5886 and defined the key lengths for the algorithms. Changed the
5887 code accordingly. The default key length is now 256 bits.
5889 * Fixed SKE key distribution function silc_ske_process_key_material
5890 when the key length is more than 128 bits. The default key
5891 length in SILC is now 256 bits.
5893 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5894 to indicate unsupported algorithm.
5896 * Renamed rijndael.c to aes.c and all functions as well.
5898 * Fixed a long standing channel key setting bug in client library.
5899 Weird that it has never surfaced before.
5901 * Fixed bug in channel deletion. If the entire channel is removed
5902 then it must also delete the references of the channel entry
5903 from the client's channel list as the client's channel entry and
5904 the channel's client entry share same memory.
5906 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Implemented CONNECT and SHUTDOWN commands in the client.
5910 * Implemented CLOSE command to the client.
5912 * Added the function silc_idlist_find_server_by_name into the
5913 files silcd/idlist.[ch].
5915 Added the function silc_idlist_find_server_by_conn into the
5916 files silcd/idlist.[ch].
5918 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * DIE command was renamed to SHUTDOWN. Updated the both code
5923 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5924 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5926 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5929 * Added function silc_server_create_connection function to create
5930 connection to remote router. My server implementation actually
5931 does not allow router to connect to normal server (it expects
5932 that normal server always initiates the connection to the router)
5933 so the CONNECT command is only good for connecting to another
5936 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5939 or some other client was kicked from the channel.
5941 Implemented the handling of the notify type to both client
5944 Implemented silc_server_send_notify_kicked to send the KICKED
5945 notify. It is used to send it to the server's primary router.
5947 * Implemented the KICK command into server and client.
5949 * Added `query' argument to the silc_idlist_get_client function
5950 to indicate whether to query the client from server or not if
5953 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5954 to indicate that the client is not channel founder.
5958 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Removed the rng context from SilcPacketContext structure and
5961 changed that the packet routine uses the Global RNG API.
5963 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Added support for quit message that client can "leave" on the
5966 channel when it quits the SILC. It is ditributed inside the
5967 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5969 Added silc_server_free_client_data that will take the
5970 signoff message as argument.
5972 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5974 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Updated parts of the protocol specification to keep it up
5979 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5982 payloads in one packet.
5984 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5985 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5986 use now the new List flag.
5988 * Also deprecated the following packet types: REPLACE_ID,
5989 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5991 * Added list support for Notify packet in server.
5993 * Added silc_server_send_notify_channel_change to send the
5994 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5995 the silc_server_send_replace_id.
5997 * Added silc_server_send_notify_nick_change to send the
5998 NICK_CHANGE notify type. Deprecates the function
5999 silc_server_send_replace_id.
6001 * Added silc_server_send_notify_join to send the JOIN notify type.
6002 Deprecates the function silc_server_send_new_channel_user.
6004 * Added silc_server_send_notify_leave to send LEAVE notify type.
6005 Deprecates the function silc_server_send_remove_channel_user.
6007 * Added silc_server_send_notify_cmode and
6008 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6009 types. Deprecates the silc_server_send_set_mode function.
6011 * Added SERVER_SIGNOFF notify type to indicate that server has
6012 quit. This means that all clients on the channel from that
6013 server will drop. This can be also used when netsplit happens.
6015 Deprecated REMOVE_ID packet type since it is not needed anymore
6018 Added silc_server_send_notify_server_signoff to send the
6019 SERVER_SIGNOFF notify type. Deprecates the function
6020 silc_server_send_remove_id.
6022 Added also silc_server_send_notify_signoff to send the
6023 SIGNOFF notify type.
6025 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6026 SILC protocol from this day on. Changed the protocol
6027 specification as well.
6029 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6030 notify type. It is used between routers to notify about
6031 topic changes on a channel.
6033 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6036 * Partly updated the protocol specification to comply with the
6037 changes now made. It is still though a bit outdated.
6039 * The JOIN notify type now takes one extra argument <Channel ID>.
6040 The packet used to be destined to the channel but now the
6041 JOIN type may be sent as list thus it is impossible to
6042 destine it to any specific channel. By adding this argument
6043 it is again possible.
6045 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Added CREDITS file. The CHANGES and CREDITS file will appear
6048 in the distribution as well.
6050 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6053 types in the server's silcd/packet_receive.c.
6055 * Implemented CMODE and CUMODE to work in router environment.
6057 * Fixed minor encoding and decoding buglet from the
6058 lib/silccore/silcmode.c.
6060 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6063 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6065 * Changed all SilcConfigServer* and silc_config_server* to
6066 SilcServerConfig* and silc_server_config*, respectively.
6069 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Associated the ID (client or server ID) to the Authentication
6072 Payload to avoid any possibility of forging. Updated the
6073 protocol specification and the code accordingly.
6075 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * The RSA key length is now save to the RsaKey context in the
6078 key generation process in lib/silccrypt/rsa.c. The key length
6079 is now used to figure out the maximum size of the block allowed
6080 to be encrypted/signed.
6082 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6083 is equivalent to the silc_mp_mp2bin but does not allocate any
6086 * Changed silc_mp_mp2bin API to take length argument. If it is
6087 non-zero then the buffer is allocated that large. If zero, then
6088 the size is approximated using silc_mp_sizeinbase, which however
6091 * Created Global RNG API which is global RNG that application can
6092 initialize. After initializing, any routine anywhere in the
6093 code (including library) can use RNG without allocating a new
6094 RNG object. This was done to allow this sort of use of the
6095 RNG in code that has no chance to allocate RNG object. All
6096 applications currently allocate this and many routines in the
6097 library use this. Affected file lib/silccrypt/silcrng.[ch].
6099 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6100 it to use the Global RNG API.
6102 * Defined Authentication Payload into protocol specification that
6103 is used during SILC session to authenticate entities. It is
6104 used for example by client to authenticate itself to the server
6105 to obtain server operator privileges.
6107 Implemented this payload into the lib/silccore/silcauth.[ch].
6108 Implemented also routines for public key based authentication
6109 as the new protocol specification dictates.
6111 Moved definitions of different authentication methods from
6112 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6114 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6115 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6116 silc_pkcs_verify_with_hash functions into the file
6117 lib/silccrypt/silcpkcs.[ch].
6119 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * The client entry's userinfo pointer must be always valid.
6122 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6123 will fail since it requires the userinfo. Now, the userinfo
6124 is allocated as "" if actual userinfo does not exist. Actually,
6125 it must exist and it is totally Ok to drop client connections
6126 that does not announce the userinfo. However, we will make
6127 this workaround for now.
6129 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6130 to return the remote port by socket.
6132 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6135 SILC_SERVER_PENDING_EXEC and added an new macro
6136 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6137 data or when error occurs while processing the pending command.
6139 Added new argument `destructor' into silc_server_command_pending
6140 and to the SilcServerCommandPending object. This destructor is
6141 now called after calling the pending callback or if error occurs
6142 immediately. If error occurs the actual pending callback won't
6143 be called at all - only the destructor. The destructor may be
6144 NULL if destructor is not needed.
6146 All this applies for client library code as well. Similar
6147 changes were made there as well for the pending commands.
6149 In the client, the application must now allocate the
6150 SilcClientCommandContext with the silc_client_command_alloc
6153 * Added reference counter to the SilcServerCommandContext. Added
6154 function silc_server_command_alloc and silc_server_command_dup
6157 Same type of functions added to the client library for the same
6160 * Removed the cmd_ident from IDListData away since it is now
6161 global for all connections. It is the command identifier used
6162 in command sending and with pending commands. The affected file
6165 * Added reference counter to the SilcSocketConnection objecet to
6166 indicate the usage count of the object. The object won't be
6167 freed untill the reference counter hits zero. Currently only
6168 server uses this, and client ignores it. The client must be
6169 set to use this too later. The affected files are
6170 lib/silccore/silcsockconn.[ch]. Added also the function
6171 silc_socket_dup to increase the reference counter.
6173 This was mainly added because it is possible that the socket
6174 is removed underneath of pending command or other async
6175 operation. Now it won't be free'd and proper DISCONNECTING
6176 flags, etc. can be set to avoid sending data to connection that
6177 is not valid anymore.
6179 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6180 the connection. After that it sets SILC_SET_DISCONNECTED.
6181 It is, however, possible that the socket data is not still freed.
6182 The silc_server_packet_process now checks that data is not
6183 read or written to connection that is DISCONNECTED. The socket
6184 get's freed when the reference counter hits zero.
6186 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Changed the client operation API: channel_message operation's
6189 `sender' is now the client entry of the sender, not the nickname
6190 and the `channel' is the channel entry, not the channel name.
6192 In the private_message operation the `sender' is now also the
6193 client entry of the sender not the nickname.
6195 Affected file is lib/silcclient/ops.h and all applications
6196 using the client operations.
6198 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Moved the calling of ops->connect() from connect_to_server_final
6201 into receive_new_id functin since that is the point when the
6202 client is actually allowed to send traffic to network. The
6203 affected file is lib/silcclient/client.c.
6205 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6208 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6209 (if needs broadcasting) instead of broadcasting the packets one
6210 by one which would make a burst in the network traffic.
6212 * Added `broadcast' argument to the functions in silcd/server.[ch]
6213 silc_server_create_new_channel[_with_id] to indicate whether
6214 to send New Channel packet to primary router.
6216 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Added new function into the silcd/server.[ch] files:
6219 silc_server_create_new_channel_with_id to create new channel with
6220 already existing Channel ID.
6222 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6223 lib/silccore/silcpacket.h. This packet is used t send list of
6224 Set Mode payloads inside one packet. Server uses this to set
6225 the modes for the channels and clients on those channels, that it
6226 announced to the router when it connected to it. The protocol
6227 specification has been updated accordingly.
6229 * The silc_server_new_channel did not handle the packet coming
6230 from normal server as it normally does not send that. However,
6231 when it announces its channels it does send it. Implemented
6232 the support for that.
6234 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6235 into the file lib/silccore/id.h.
6237 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Fixed memory leaks in the functions silc_idlist_del_client,
6240 silc_idlist_del_channel and silc_idlist_del_server in the file
6241 silcd/idlist.c. All of those leaked like a sieve.
6243 * Fixed some small memory leaks in the client's function
6244 silc_client_notify_by_server.
6246 * Added functions into silcd/server.c: silc_server_announce_clients,
6247 silc_server_announce_channels and silc_server_announce_server.
6248 These functions are used by normal and router server to announce
6249 to its primary router about clients, channels and servers (when
6250 router) that we own. This is done after we've connected to the
6253 These functions effectively implements the following packet types:
6254 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6255 and SILC_PACKET_NEW_ID_LIST.
6257 * Added new functions into the silcd/packet_receive.[ch]:
6258 silc_server_new_id_list, silc_server_new_channel_list and
6259 silc_server_new_channel_user_list to handle the incoming
6260 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6262 * Added support of changing Channel ID in the function
6263 silc_server_replace_id. If the server that announces a channel
6264 to the router already exists in the router (with same name but
6265 with different Channel ID), router is responsible to send
6266 Replace ID packet to the server and force the server to change
6267 the Channel ID to the one router has.
6269 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6270 client that the Channel ID has been changed by the router. The
6271 normal server sends this to the client. Client must start using
6272 the new Channel ID as the channel's ID.
6274 Implemented handling of this new type into lib/silcclient/client.c
6275 into the function silc_client_notify_by_server.
6277 * Added new function silc_idlist_replace_channel_id into the files
6278 silcd/idlist.[ch] to replace the Channel ID.
6280 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Call silc_server_command_identify_check always when processing
6283 the IDENTIFY command in silcd/command.c
6285 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6288 send keepalive packets. The packet can be sent by clients,
6289 servers and routers.
6291 Added function silc_socket_set_heartbeat into the file
6292 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6293 If not set, the heartbeat is not performed. The actual
6294 heartbeat is implemented in the low level socket connection
6295 library. However, application is responsible of actually
6298 Added silc_server_send_heartbeat to send the actual heartbeat
6299 packet into silcd/packet_send.[ch]. Server now performs
6300 keepalive with all connections.
6302 * Added silc_task_get_first function into lib/silcutil/silctask.c
6303 to return the timeout task with shortest timeout. There was a bug
6304 in task unregistration that caused problems. TODO has been
6305 updated to include that task system must be rewritten.
6307 * The client library will now resolve the client information when
6308 receiving JOIN notify from server for client that we know but
6309 have incomplete information.
6311 * Rewrote parts of silc_server_remove_from_channels and
6312 silc_server_remove_from_one_channel as they did not remove the
6313 channel in some circumstances even though they should've.
6315 * Encryption problem encountered in server:
6317 The LEAVE command used to send the Channel Key packet to the
6318 router immediately after generating it. However, the code
6319 had earlier sent Remove Channel user packet but not immediately,
6320 ie. it was put to queue. The order of packets in the router
6321 was that Channel Key packet was first and Remove Channel User
6322 packet was second, even though they were encrypted in the
6323 reverse order. For this reason, MAC check failed. Now, this
6324 is fixed by not sending the Channel Key packet immediately but
6325 putting it to queue. However, this is more fundamental problem:
6326 packets that are in queue should actually not be encrypted
6327 because packets that are sent immediately gets encrypted
6328 actually with wrong IV (and thus MAC check fails). So, packets
6329 that are in queue should be encrypted when they are sent to
6330 the wire and not when they put to the queue.
6332 However, the problem is that the current system has not been
6333 designed to work that way. Instead, the packet is encrypted
6334 as soon as possible and left to the queue. The queue is then
6335 just purged into wire. There won't be any fixes for this
6336 any time soon. So, the current semantic for packet sending
6339 o If you send packet to remote host and do not force the send
6340 (the packet will be in queue) then all subsequent packets to the
6341 same remote host must also be put to the queue. Only after the
6342 queue has been purged is it safe again to force the packet
6345 o If you send all packets immediately then it safe to send
6346 any of subsequent packets through the queue, however, after
6347 the first packet is put to queue then any subsequent packets
6348 must also be put to the queue.
6350 Follow these rules and everything works fine.
6352 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Added new function silc_server_remove_clients_by_server to
6355 remove all client entries from ID list when the server connection
6356 is lost. In this case it is also important to invalidate all
6357 client entires as they hold the invalid server entry. This
6358 fixes fatal bug when server has lost connection and will reconnect
6361 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Made some sanity checks to silc_server_daemonise like to check
6364 whether the requested user and group actually exists.
6366 * Added sanity check to SKE's silc_ske_responder_finish to check
6367 that the public and private key actually is valid.
6369 * Invalidate the client's nickname when receiving Replace ID
6370 packet and the Client ID is being replaced. This means that the
6371 server will query the nickname if someone needs it (client)
6374 * Sort the ID Cache in client library when the ID Cache data
6375 has changed (needs sorting).
6377 * Do not allow for SILC client to create several connections to
6378 several servers. The client does not support windows right now
6379 and generating multiple connections causes weird behaviour.
6381 Irssi-silc client does support windows and can handle several
6382 connections without problems, see: www.irssi.org and SILC plugin.
6384 * Fixed some places where client was added to the IDList. The
6385 rule of thumb is following (in order to get everything right):
6386 If the client is directly connected local client then the
6387 `connection' argument must be set and `router' argument must be
6388 NULL to silc_idlist_add_client function. If the client is not
6389 directly connected client then the `router' argument must
6390 bet set and the `connection' argument must be NULL to the
6391 silc_idlist_add_client function.
6393 * The funtion silc_server_packet_send_local_channel actually did
6394 not check whether the client was locally connected or not. It
6395 does that now. Fixed a bug related to LEAVE command.
6397 * Fixed Remove Channel User payload parsing bug in server's
6398 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6400 * The server's silc_server_save_channel_key now checks also the
6401 global ID list for the channel as it might not be in the local
6402 list. Fixed a bug related to LEAVE command.
6404 * Is this the end of the [<unknown>] buglet that has been lurking
6405 around for a long time? A little for loop fix in server's
6406 silc_server_command_whois_parse that is used by both IDENTIFY
6407 and WHOIS command. At least, this was a clear bug and a cause
6408 of one type of [<unknown>] buglet.
6410 * WHOIS and IDENTIFY commands call the function
6411 silc_server_command_[whois/identify]_check function even if
6412 we are not router server.
6414 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Added --with-gmp configuration option. If set the GMP
6417 is always compiled in the SILC source tree. If not set then
6418 it is checked whether the system has the GMP3 installed. If
6419 it has then the GMP won't be compiled (the system's headers
6420 and library is used), if it doesn't have it then the GMP is
6421 compiled in the SILC source tree.
6423 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Changed RSA private exponent generation to what PKCS #1
6426 suggests. We try to find the smallest possible d by doing
6427 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6428 not security fix but optimization.
6430 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6432 * Added new config entry [Identity] to fork the server and run
6433 it as specific user and group. A patch from Bostik.
6435 * Imported Dotconf configuration library into lib/dotconf.
6436 This will be used to create the SILC configuration files later.
6437 It will appear in the distsribution after this commit.
6439 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * A big code auditing weekend happening. Auditing code for
6442 obvious mistakes, bugs and errors. Also, removing any code
6445 Removed files for being obsolete:
6447 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6448 inline in the file lib/silcutil/silcbuffer.h)
6450 o lib/silcutil/silcbufutil.c (the header has inline versions)
6452 Changed code to fix possible error conditions:
6454 o The buffer formatting routines now check that the destination
6455 buffer really has enough space to add the data. This applies for
6456 both buffer formatting and unformatting
6457 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6458 unformatting was changed to accomodate following rules:
6459 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6460 sent to the function while XXX_*STRING will not allocate or copy
6461 the data into the buffer. Instead it sets the pointer from the
6462 buffer into the pointer sent as argument (XXX_*STRING used to
6463 require that the pointer must be allocated already). This change
6464 makes this whole thing a bit more consistent and more optimized
6465 (note that the data returned in the unformatting with XXX_*STRING
6466 must not be freed now). The routines return now -1 on error.
6468 o Tried to find all code that use buffer_format and buffer_unformat
6469 and added return value checking to prevent formatting and
6470 especially unformatting errors and possible subsequent fatal
6473 o Changed ske->x and ske->KEY to mallocated pointers in
6474 lib/silcske/silcske.h. Fixed possible data and memory leak.
6476 o Added return value checking to all *_parse* functions. Fixed
6477 many memory leaks as well.
6479 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6480 so that buffer overflows would not happen. All code now also
6481 checks the return value as it can fail.
6483 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Added reconnection support to server if the normal server looses
6486 its connection to the router (for example if router is rebooted).
6487 The server performs normal reconnection strategy implemented
6488 to the server. Affected file silcd/server.c.
6490 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Added new packet type SILC_PACKET_SET_MODE that is used to
6493 distribute the information about changed modes (for clients,
6494 channels and clients channel modes) to all routers in the
6495 network. Updated the protocol specification accordingly.
6497 Added functions into silcd/packet_send.c and
6498 silcd/packet_receive.c: silc_server_send_set_mode,
6499 silc_server_set_mode.
6501 Added new files silcmode.[ch] into lib/silccore that implements
6502 the encoding and decoding of Set Mode Payload. Added new type
6503 SilcSetModePayload. Moved the definitions of different modes
6504 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6506 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Oops, a little mistake in server's connection authentication
6509 protocol. The protocol is not ended with FAILURE but with
6510 SUCCESS if the authentication is Ok. :) Affected file is
6513 * Implemented NICK_CHANGE notify handling in server in the file
6514 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6515 the local clients on the channel. After the changing nickname
6516 in router environment snhould work and the [<unknown>] nickname
6517 should appear no more.
6519 The silc_server_replace_id function that receives the Replace ID
6520 payload now sends the NICK_CHANGE notify type also in the file
6521 silcd/packet_receive.c
6523 * Changed WHOIS and IDENTIFY command to support the maximum amount
6524 of arguments defined in protocol specs (3328 arguments). This
6525 fixed a bug that caused problems when there were more than three
6528 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Added extra parameter, command identifier, to the
6531 silc_client_send_command so that explicit command identifier
6534 Changed that ID list routines uses specific command identifier
6535 when sending WHOIS/IDENTIFY requests to the server so that they
6536 can be identified when the reply comes back.
6538 Affected files lib/silcclient/command.[ch],
6539 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6541 * Added `sender' argument to silc_server_packet_send_to_channel
6542 to indicaet the sender who originally sent the packet to us
6543 that we are now re-sending. Ignored if NULL. Affected file
6544 silcd/packet_send.[ch].
6546 * Added some server statistics support in silcd/server_internal.h
6547 SilcServerStatistics structure and around the server code. Also
6548 send some nice statistics information when client is connecting
6551 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * Fixed channel ID decoding in server's JOIN command reply in
6554 silcd/command_reply.c
6556 * Fixed braodcasting of replace ID payload to not to send it if
6557 we are standalone server in silcd/packet_receive.c.
6559 * Fixed all channel message sending routines to not to send
6560 packets to clients that has router set, since they are routed
6561 separately in the same function earlier. Affects file
6562 silcd/packet_send.c and all channel packet sending functions.
6564 * In USERS reply, res_argv[i] are not allocated, the table
6565 is allocated. Thus changed that free the table, not its
6568 * In server's whois_check and identify_check if the client is
6569 locally connected do not send any WHOIS commands - they are not
6572 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Fixed some minor bugs in client when sending WHOIS command. The
6575 arguments was in wrong order.
6577 * Removed statis function add_to_channel from server in
6578 silcd/command.c that was previously used with the joining but
6581 * Tested USERS command in router environment successfully with two
6582 routers, two servers and two clients.
6584 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Reorganized the USERS command and command reply in client library
6587 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6588 When the command is given by user we register a pending command
6589 callback that will reprocess the command after the reply has been
6590 received from the server. When reprocessing the packet we then
6591 display the information. Thus, the USERS information is displayed
6592 now in the command callback instead of in the command reply
6593 callback. The processing of the command is same as previously
6594 when server has sent the command reply in the JOINing process.
6596 * Added to USERS command in silcd/command_reply.c to join the client,
6597 we didn't use to know about, to the channel after we've created
6598 a client entry for it. Also, for clienet we did know already still
6599 check whether it is on the channel or not and add it if not.
6601 * Removed silc_server_command_join_notify as the function and its
6604 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Changed the client's pending command handling to the same as the
6607 server's pending command handling. It is also now possible to
6608 execute command reply functions from other command reply
6609 function as the function callbacks for commands and command
6610 replies are one and same. The pending commands are not static
6611 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6612 in client connection context. Thus, pending commands are server
6613 connection specific as it is convenient.
6615 Changed the function silc_client_command_pending and
6616 silc_client_command_pending_del and added new function
6617 silc_client_command_pending_check. Removed the
6618 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6621 * Added cmd_ident, current command identifier, to the client
6622 connection context in lib/silcclient/client.h to keep track on
6623 command identifiers used in command sending. Client's command reply
6624 function handling now supports the mandatory command identifiers.
6626 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6627 funtions in client to fully support pending command callbacks.
6629 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6630 as one of the arguments to the application in the command reply
6633 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6634 before first releasing SILC but came back. Now it is removed again
6635 and should come back nomore. The FORWARDED flag was used only
6636 by the JOINing procedure by forwarding the command packet to router.
6637 Now, the JOINing procedure has been changed to more generic (due
6638 to various router environment issues) and FORWARDED is not needed
6639 anymore for anything. The protocol specification is yet to be
6642 Now, removed silc_server_packet_forward from server and the flag
6643 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6645 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Renamed NAMES command to USERS command. The NAMES was named that
6648 due to historical reasons. Now it is renamed. Also, rewrote
6649 parts of the USERS command. The nickname list is not sent anymore
6650 by the server. Only Client ID and mode lists are sent in the USERS
6651 command. Changed this also to the protocol specification.
6653 The client now resolves the names and stuff after it receives
6654 the USERS list from the server when joining to the channel.
6656 * WHOIS and IDENTIFY commands has been changed to support multiple
6657 Client ID's per command. One can now search for multiple users
6658 in the network by sending only one WHOIS or IDENTIFY command.
6659 Changed the code and the protocol specifications.
6661 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6662 uses silc_server_command_whois_parse to parse the request. */
6664 * If normal server, do not parse the WHOIS and IDENTIFY requests
6665 before sending it to the router. Saves some time.
6667 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Fixed JOIN command on client library. Wrong number of arguments
6670 used to crash the client.
6672 * Added silc_server_channel_has_global function to check whether
6673 channel has global users or not.
6675 * Added silc_server_channel_has_local function to check whether channel
6676 has locally connected clients on the channel.
6678 * The silc_server_remove_from_one_channel now checks whether the
6679 channel has global users or not after given client was removed from
6680 the channel. It also checks whether the channel has local clients
6681 on the channel anymore. If it does not have then the channel entry
6682 is removed as it is not needed anymore.
6684 * The silc_server_notify now checks on JOIN notify whether the joining
6685 client is one of locally connected or global. If it is global then
6686 the channel has now global users on the channel and that is marked
6687 to the channel entry. Also, it now saves the global client to
6688 global list who is joining and JOINs it to the channel. This is
6689 for normal server, that is.
6691 Changed silc_server_send_notify_on_channel,
6692 silc_server_packet_relay_to_channel and
6693 silc_server_packet_send_to_channel check if we are normal server
6694 and client has router set (ie. global client) do not send the
6695 message to that client, as it is already routed to our router.
6697 * Implemented LEAVE notify type handling in silc_server_notify
6700 * Tested LEAVE command in router environment successfully. Tested
6701 with two routers, two servers and two clients.
6705 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6707 * Implemented SIGNOFF notify type handling in silc_server_notify
6710 * silc_server_remove_id now removes the client entry from all channels
6711 it has joined and thusly sends SIGNOFF notify type.
6713 * Rewrote the NAMES list generation in server by removing two excess
6714 loops. The lists are created now inside one loop.
6716 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * silc_server_remove_channel_user checks now also global list
6719 for channel and client.
6721 * silc_server_new_channel_user checks now both local and global
6722 list for channel and client. Fixed a bug in client id decoding.
6723 Used to decode wrong buffer.
6725 * silc_server_channel_message checks now both local and global
6726 list for channel entry.
6728 * Tested channel joining (hence JOIN) in router environment
6729 successfully. Tested with two routers, two servers and two
6732 * Tested channel message sending in router environment successfully.
6734 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Added silc_server_save_channel_key into server.[ch] to save the
6737 received channel key in Channel Key payload processing. It is
6738 also used in JOIN command reply handling.
6740 Equivalent function silc_client_save_channel_key added into
6741 client.[ch] into client library.
6743 * Changed JOIN command reply to send information whether the channel
6744 was created or not (is existing already) and the channel key
6745 payload. Changed protocol specs accordingly.
6747 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6748 the request was sent by ID and not by nickname. Crashed on
6751 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6754 now correctly save the received data.
6756 * silc_server_free_sock_user_data now notifies routers in the
6757 network about entities leaving the network.
6759 At the same time implemented functions silc_server_remove_id
6760 and silc_server_send_remove_id to receive and send REMOVE_ID
6761 packets. The packet is used to notify routers in the network
6762 about leaving entities. The ID removed will become invalid in
6765 * Added function silc_idlist_del_server into server. Removes and
6766 free's server entry from ID list.
6768 * silc_server_private_message function now checks, if we are router,
6769 that the destination ID really is valid ID, naturally.
6771 * In router when NEW_ID packet is received (for new client) the
6772 hash of the Client ID is saved in the ID Cache but the
6773 client->nickname is set to NULL, instead of putting the hash
6776 IDENTIFY command now also checks that client->nickname must be
6777 valid. If it is not if will request the data from the server who
6778 owns the client. Added new function
6779 silc_server_command_identify_check.
6781 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6782 to set the command to already allocated Command Payload.
6784 * Tested private message sending in router environment with two
6785 routers, two servers and two clients. Fixed minor bugs and now
6788 * Fixed segfault from client's NAMES command. Used to crash if
6791 * Forwarded packets must not be routed even if it is not destined
6792 to the receiver. Changed server code comply with this.
6794 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Added `require_reverse_mapping' boolean value to ServerParams
6797 structure. If TRUE (not default) the server will require that
6798 the connecting host has fully qualified domain name.
6800 If the reverse mapping is not required and hostname could not be
6801 found the IP address is used as hostname.
6803 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Implemented version string checking to both client and server.
6806 The check is incomplete currently due to the abnormal version
6807 strings used in development version of SILC.
6809 * Changed all command functions in server to use the new
6812 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Changed char *data to unsigned char *data in ID Cache system to
6815 support binary data as ID Cache data. Changed code to support
6816 binary data in lib/silccore/idcache.c.
6818 * Renamed silc_server_packet_relay_command_reply to
6819 silc_server_command_reply as it is normal packet receiving
6820 function. Rewrote the function to accept command replys for
6821 servers and not only for clients.
6823 * Mark remote router always as registered server if we are connecting
6824 to it. Otherwise, commands sent by the router to us are ignored.
6826 * All ID List find routines now returns the ID Cache Entry pointer
6827 as well if requested.
6829 * WHOIS command works now in router environment, tested with two
6830 routers, two servers and two clients.
6832 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6833 in router environment (as it is almost equivalent to WHOIS) but
6834 hasn't been tested thoroughly. Added new functions:
6836 silc_server_command_identify_parse
6837 silc_server_command_identify_send_reply
6838 silc_server_command_identify_from_client
6839 silc_server_command_identify_from_server
6841 * Disabled route cache adding because adding two different ID's with
6842 same IP replaces the old cache entry thus giving wrong route.
6843 The entry->router->connection is always the fastest route anyway
6844 so route cache may not be needed. Of course, new routes maybe
6845 established after receiving the ID when the entry->router->connection
6846 might not be anymore the most optimal.
6848 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Add route cache for received ID for fast routing.
6852 * Added silc_server_packet_route to route received packet on router
6853 that is not destined to us.
6855 * Renamed silc_server_get_route to silc_server_route_get.
6857 * Added id_string and id_string_len fields into SilcServer to
6858 include encoded ServerID for fast comparing without excess
6859 encoding of the ID's.
6861 * Cleaned up WHOIS command on server side. Added following static
6864 silc_server_command_whois_parse
6865 silc_server_command_whois_check
6866 silc_server_command_whois_send_reply
6867 silc_server_command_whois_from_client
6868 silc_server_command_whois_from_server
6870 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6871 arguments in command replies. All command functions should be
6872 updated to use this macro.
6874 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Minor typo fixes on command reply handling on server.
6878 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Added silc_server_command_add_to_channel internal routine to add
6881 the client to the channel after router has created the channel and
6882 sent command reply to the server.
6884 * Added generic silc_server_send_command to send any command from
6887 * Use static buffer with ID rendering instead of duplicating data.
6889 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Fixed a channel user mode bug when joining to a channel server gave
6892 everybody channel founder rights, oops.
6894 * We mark ourselves as the router of the incoming server connection
6895 if we are router ourselves. This way we can check in some packet
6896 sending functions whether it is locally connected server. For
6897 incoming router connections we put NULL.
6899 * For router sending packets locally means now always sending the
6900 packet cell wide; to local clients and local servers. For normal
6901 server sending packet locally means sending it to only local
6904 * Fixed the JOIN command to really work in router environment. If the
6905 channel is created it is always created by the router. Router is
6906 also responsible of making the initial joining to the channel,
6907 sending JOIN notify to the sending server and distributing
6908 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6909 does not exist server doesn't do anything else but forward the
6910 command to the router which performs everything.
6912 * Added silc_server_send_channel_key function to send the Channel Key
6915 * Added silc_server_create_channel_key to create new channel key. The
6916 channel key is now re-generated everytime someone joins or leaves
6917 a channel, as protocol dictates. Note: channel->key_len is the
6920 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6922 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6923 packet_receive.[ch] to separate packet sending and receiving
6924 routines. The server.[ch] now includes everything else including
6925 actual packet processing (writing and reading data) and other
6928 Renamed silc_server_private_message_send_internal to
6929 silc_server_send_private_message. The routine is still though
6930 used only to relay private messages as server does not send
6931 private messages itself.
6933 Renamed silc_server_new_channel to silc_server_create_new_channel
6934 and added new function sicl_server_new_channel that handles the
6935 incoming New Channel packet. Added also new sending function
6936 silc_server_send_new_channel to send New Channel Payload.
6938 * Added new function silc_server_notify to process incoming notify
6939 packet to the server/router. Server may then relay the notify
6940 to clients if needed.
6942 * Added new function silc_server_new_channel_user to process incoming
6943 New Channel User packet. Router will redistribute the packet and
6944 send JOIN notify to its local clients and locally connected servers
6945 if needed. Normal server will send JOIN notify to its local client
6946 on same channel when received this packet. Added also corresponding
6947 sending function silc_server_send_new_channel_user to sent the
6950 * Added boolean route argument to send_notif_to_channel and
6951 packet_send_to_channel functions to attempt to route the packet
6952 if it is TRUE and send only locally if it is FALSE.
6954 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6956 * silc_server_replace_id now broadcasts the received replace ID
6957 packet if it is not broadcast packet already. The router must
6958 broadcast to inform other routers about changed ID.
6960 * Added backpointer to server's router into SilcServer context in
6961 silcd/server_internal.h.
6963 * Fixed silc_server_packet_broadcast to send correct broadcast
6966 * The channel key is now distributed to the local client as soon
6967 as it is received from the router (in router environment) so that
6968 no other packet may be sent for the channel until client has
6971 * silc_server_remove_channel_user now broadcasts the received
6972 Remove Channel User packet if it is not broadcast packet already.
6973 The router must broadcast to inform other routers about removed
6976 * Added users field into SilcPacketContext that is a reference count
6977 of the context. One can increase the reference count by calling
6978 silc_packet_context_dup which is now changed to just increase the
6979 reference count instead of duplicating the data. The reference
6980 count is decresed by calling silc_packet_context_free that will
6981 free the data after the reference count hits zero.
6983 For now on the packet context and everything allocated into it
6984 (including the raw packet from network) must be freed by calling
6985 the new silc_packet_context_free function. Added also new function
6986 silc_packet_context_alloc that must be used now to allocate the
6987 context. This also means that if a routine is asynchronous from
6988 silc_[client/server]_packet_parse_type the packet context must
6989 be duplicated by calling silc_packet_context_dup. Otherwise it
6990 gets free'd after silc_[client/server]_packet_parse_type returns.
6991 Also, one must remember that if packet is duplicated then its
6992 reference count must be decresed by calling the free function as
6993 many times as it was duplicated.
6995 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6996 from both client and server.
6998 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7000 * Made joining to a channel working in router environment.
7002 * Cleaned up JOIN command on server side and create function
7003 silc_server_command_join_channel internal routine to make the
7006 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7008 * Changed silc_command_pending list to SilcDList. Also, added
7009 `ident' field to SilcServerCommandPending structure to identify
7010 the reply and to call correct callback.
7012 Added silc_server_command_pending_check function to replace the
7013 corresnponding macro. The silc_command_pending list is not
7016 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7017 to set identifier to previously allocated Command Payload. It
7018 is used to set identifier for command when resending Command
7021 * Added silc_command_payload_encode_payload to encode Command
7022 Payload buffer from SilcCommandPayload structure.
7024 * Added silc_argument_payload_encode_payload to encode Argument
7025 payload buffer from SilcArgumentPayload structure.
7027 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7029 * Changed WHOIS command to support router connection on server side.
7030 The whois request is always sent to router unless the server is
7031 standalone server. After server has received the reply from the
7032 router will it send the reply to the client.
7034 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7035 broadcast received broadcast packet. The function is used only
7036 by router. The broadcast packet is always sent to the router's
7039 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7040 render given ID to printable string, for log files for example.
7042 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Made basic router to router connections working. At least they
7045 can now connect to each other but nothing really works the way
7046 they are supposed - yet.
7048 * Added new initiator token to RouterConnection configuration
7049 file in silcd/serverconfig.[ch]. It is used to tell whether we
7050 are the initiator to the remote router or whether we'll expect
7051 the other end to connect.
7053 * Moved registering of listener task to silc_server_init, hence
7054 the server starts listenning as soon as it is run, even if it
7055 does not have connections to other routers. Let's see how well
7058 * Changed default connection retry timeouts for more suitable in
7061 * Removed cipher and such arguments from silc_idlist_add_client
7062 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7063 Added new function silc_idlist_add_data to add the keys and stuff
7066 * Added SilcIDListData structure and added it to SilcClientEntry
7067 and SilcServerEntry as their first field in the structure. This
7068 way we can explicitly cast the ID entries to the SilcIDListData
7069 structure and get common data for the entries. In past, we had
7070 to first check what type of connection it is and then cast it to
7071 correct ID entry type. Now, we can directly cast the opaque
7072 pointer to the SilcIDListData (no matter what ID entry it actually
7073 is) and get the data needed.
7075 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7077 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7078 in some circumstances even if threre were timeout tasks, though not
7079 IO tasks, but tasks anyway. Now fixed.
7081 * Defined SilcServerConnection structure to hold connection specific
7082 stuff about directly connected servers and routers. The definition
7083 is currently in silcd/server_internal.h. I thought about having
7084 a bit more important role fro this struct but for now it is used
7085 only when connecting to other server (or router actually).
7087 * Added connecting retry support in server when connecting to
7088 router(s). The retry feature implement exponential backoff
7089 algorithm. Also, added SilcServerParams structure to hold default
7090 parameters for server. For now, it include these retry settings
7091 and are hard coded. After server is moded to be as Silc Server
7092 Library this structure will be more important.
7094 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Changed client librarys channel->clients table to SilcList and
7097 changed code accordingly.
7099 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Changed client's channel table to SilcList and changed code
7102 accordingly. Also changed SilcChannelClientEntry to include back-
7103 pointer to the channel so that client entry can use that structure
7104 as list as well and we have fast cross-reference to the channel.
7105 This change dramatically decreased the complexity of channel
7106 handling with client entry and vice versa (removed one extra
7107 loop when searching for channel entry from many functions).
7109 * Changed server->sim from table to SilcDList and changed code
7112 * NAMES command can now be used from user interface. It will show
7113 the user list on the channel, neatly.
7115 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7116 Code now saves realname of the user if it becomes available.
7118 * Renamed configure.in to configure.in.pre and made ./prepare
7119 script to automatically add correct version string to
7120 configure.in which it creates from configure.in.pre.
7122 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * NAMES command reply now shows users mode with the nickname when
7127 * Moved silc_client_ch[u]mode[_char] functions from
7128 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7129 place sucks, they are utility functions and should be in some
7132 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7134 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7137 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Added TRQ (efficient deque and list library) into lib/trq. This is
7142 a very good list library that is currently used in the SILC. Defined
7143 SilcList API over the library because I didn't like the API very
7144 much. See lib/trq/silclist.h for the API and examples of how to
7145 use the API. Fixed various places in the code to use the new
7146 SilcList API. The SilcList is meant for lists that has a structure
7147 already defined as a list. It is not suitable to add just some
7148 context to the list (in TRQ, the context is the list actually).
7150 So, I defined SilcDList that can be used for the purpose where
7151 predefined list structure does not exit. This can be used as
7152 such list. Now some context just can be added to the SilcDList.
7153 Currently this list is not used in the SILC just yet, though there
7154 are a lot places where this can replace dynamically allocated
7155 tables and I will fix these places, later, to use SilcDList.
7156 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7157 and use TRQ internally).
7159 Also fixed some annoying warning messages that the original TRQ
7160 code generated. Also minor changes to TRQ's Makefile.in.
7162 * Added support for querying by Client ID to both WHOIS and
7163 IDENTIFY commands into server, as required by the protocol.
7165 * Removed method function pointers from SilcBuffer structure. They
7166 weren't used to anything and just increased the context size for
7167 no good reason. This change also made silc_buffer_alloc and
7168 silc_buffer_free functions inline functions.
7170 * Disabled command flooding detection support until it's fixed so
7171 that it accepts commands in but does not execute them more than once
7174 * Added silc_net_localhost(), to return local hostname, into
7175 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7176 that must be initialized before calling silc_client_init.
7178 * Added new function: silc_server_send_notify_on_channels to send
7179 notify messages to all channels client has joined. It is assured
7180 that the message is sent only once per client.
7182 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7183 lib/silcutil/silcutil.[ch] as silc_format function. The new
7184 function is generic and is used by server as well, not only by
7185 the logging routines.
7187 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7188 the provided version string was not acceptable. Added new function:
7189 silc_ske_check_version into lib/silcske/silcske.h. The function
7190 must be implemented by the application (client or server) and it
7191 does not reside in the SKE library. The function checks the version
7192 string remote end sent.
7194 * Added back pointers (to opaque context and to SilcSocketConnection)
7195 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7197 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7198 duplicate packet context structure.
7200 * Changed `notify' client operation to send same arguments as client
7201 receives from server except for ID's. ID's are mapped to correct
7202 ID entry and that is returned. Also, if channel entry is not sent
7203 by server but the notify is for channel the channel entry is sent
7204 to application (otherwise application doesn't know that it is for
7205 channel (library gets it from packet's Destination ID)).
7207 * Added silc_client_remove_from_channels into client library to
7208 remove a client from all channels it has joined to. Used when
7209 received SIGNOFF notify from server. Added also new function
7210 silc_client_replace_from_channels to replace old ID entry with
7211 new ID entry on all channels. Used when received NICK_CHANGE
7214 * Fixed ID Cache list handling in silc_idlist_get_client in
7215 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7216 to get (or query) client by ID.
7218 * Updated TODO list.
7220 * Added connection authentication status message defined by the
7221 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7222 support for these into the code in client and server side.
7224 * Added generic function silc_client_send_command to send any command
7225 with variable argument list. Application should use this function
7226 to send commands if the command functions provided by the library
7227 does not suite for the application's user interface needs.
7229 * Added new `failure' client operation. Application is notified about
7230 received failure packet if client is executing a protocol. In this
7231 case the protocol's execution has failed.
7233 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7234 is required by the protocol.
7236 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7237 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7240 * Added status flag to SilcSKE object to indicate realtime status
7241 of the SKE protocol.
7243 * Application receives now exactly same command reply arguments as
7244 the library receives from server. However, if ID is received the
7245 corresponding ID entry is returned to the application (eg. Client
7246 ID is mapped to correct SilcClientEntry entry and that is returned).
7247 Changed command_reply client operation due to this change.
7249 * Changed all ID's in commands and in command replys as ID Payloads.
7250 Change affected both client and server side codes.
7252 All ID's sent in SILC network (with execption of ID's in SILC
7253 Packet header) are sent in ID Payload to support variable length
7256 * Server now notifies nick changes and notifies all clients on
7257 the channels about the new nickname (about the new Client ID,
7260 * Implemented CMODE command to change channel modes. Supports all
7261 channel modes defined by the protocol specs except ban and invite
7262 lists. (Also, private channel key mode is supported but support for
7263 setting private channel key in client is missing, thus, this mode
7264 has no effect on client side (except that server requires that the
7265 client uses private channel key and normal channel traffic does not
7268 Also, invite mode works per se, but INVITE command does not work
7269 yet correctly, so you can set channel as invite only channel but
7270 inviting clients to the channel does not work (it is yet to be
7271 thought what's the best way to do it).
7273 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7274 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7275 Implemented CUMODE command to change user's mode on the channel.
7276 Supports all modes defined by the protocol specs.
7278 * Added NAMES command reply to return users modes on the channel.
7280 * Removed unnecessary and slow ciphers from lib/silccrypt.
7282 * Set SO_KEEPALIVE option to connection sockets by default.
7284 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7286 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7287 redefined the Notify Payload into protocol specs.
7289 * Added silc_id_payload_parse_id to get ID directly from raw
7292 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7294 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7295 accept searching by Client ID as well.
7297 * Added support for LEAVE and SIGNOFF notify types in client library.
7299 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7300 to parse ID Payload from raw data.
7302 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * Added flags parameter into silc_ske_assemble_security_properties
7305 function in lib/silcske/silcske.[ch].
7307 * Changed notify client operation to fit better for notify messages
7308 sent by server. The notify payload received from server is now
7309 passed to the application (after parsing it to SilcNotifyPayload).
7310 It is application's responsibility to retrieve the arguments
7311 from the payload and show the message the way it wants. The message
7312 sent by server is implementation specific.
7314 * Changed public keys to comply with the protocol specification.
7315 Old public keys are not supported anymore and are not compatible.
7317 * Removed nickname from Channel Payload as the latest draft removed
7318 it. The client must resolve the nickname from the NAMES command
7319 reply received when it joined the channel.
7321 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7323 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7325 * Fixed some errors in protocol specification drafts.
7327 * Created lib/silccore/silcnotify.c to implement Notify Payload
7328 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7329 generic payloads described by protocol specifications. The file
7330 includes implementations for ID Payload and Argument Payload.
7332 * Changed Command Payload implementation to use the new Argument
7333 Payload. Changed command_xxxx_payload to command_payload_xxxx
7334 to comply with SILC coding conventions.
7336 * Added suppport for Argument Payload handling in Notify Payload
7337 implementation as protocol requires it. Added the new support
7338 into server and client lib as well.
7340 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * Added support for multiple nicknames on same channel. [n] is
7343 added locally to the nickname if there are more than one same
7344 nicknames on the channel.
7346 * Server now sends all nicknames that matched WHOIS request.
7347 Client also shows the list received from server.
7349 * Added TOPIC command to client side. User can now set and show
7350 current topic on channel.
7352 * Added MOTD command to client and server. Also, server sends the
7353 motd when client connects to the server.
7355 * Changed version strings to comply ISO 8601.
7357 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7359 * Fixed protocol error handling in client library. It should now
7360 cope even if the SKE fails for some reason.
7362 * Made new protocol specification drafts for submitting to IETF.
7364 * Implemented TOPIC command to server in silcd/command.c.
7366 * Added two new notify types into lib/silccore/silcnotify.h:
7367 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7368 notify nickname change and topic setting/change on a channel.
7370 * API change of command_reply operation in client library. The
7371 application gets now the status type received from server as well.
7373 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7377 * Cras fixed and optimized the packet handling even further and
7378 it should work now. Minor change to the prototype of function
7379 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7381 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7383 * Added new function into lib/silcutil/silcschedule.[ch]:
7384 silc_schedule_with_fd to select() a specified fd. The function
7385 returns after timeout expires or data arrives or goes. The
7386 function is used by packet routines to wait that all data is
7387 received from network.
7389 * Fixed data reading from network in lib/silccore/silcpacket.c.
7390 The code now assures that all data is read from the fd and then
7391 continues packet processing. This was a bug fix since the code
7392 used to drop some data in some circumstances.
7394 * Added new function into lib/silcclient/client.[ch]:
7395 silc_client_start_key_exchange to start key exchange after
7396 connection has been established to server. The code internally
7397 now uses this funtion but its main purpose was to provide it
7398 for applications that perform their own connecting. After
7399 application has created a connection it merely calls this
7400 function to start the key exchange between client and server.
7401 The library takes care of everything else after that.
7403 Updated also lib/silcclient/README to explain the usage of
7406 * Do not send to application information that connection has
7407 been established. Application gets notified it by connect
7410 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Applied cras's patch to add silc_schedule_one function. The
7413 function runs scheduler once and returns.
7415 * Fixed the scheduler after cras messed it up. The timeout
7416 handling works now as it's supposed to work.
7418 * Added into lib/silccore/ silcnotify.h to include notify
7419 message types support. Changed silc_server_send_notify*
7420 functions, in server.[ch], to support those new notify types.
7421 Added the support for the notify types into client library,
7422 as well. Added new notify client operation into ops.h in
7425 * Changed silc_server_packet_send_to_channel to send normal
7426 packets instead of just channel message packets. The function
7427 is now used to send the notify packets to channels. It is not
7428 used to send channel message packets anymore, as server never
7431 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7432 va_arg()s as it seems to require it nowadays. I guess, if SILC
7433 is compiled with older va_arg() the new code should work anyway.
7435 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * Splitted core library. Core library (lib/silccore) includes
7438 now only SILC protocol specific core (and common) components.
7439 Created new utility library (lib/silcutil) that includes more
7440 generic purpose stuff. The stuff for util library was taken
7441 from the old core library. This was minor and easy split.
7443 * Created SILC Client Library (lib/silcclient) that includes
7444 implementation of the SILC client without user interface. This
7445 was major move from silc/ directory. The code has been changed
7446 so that it is transparent towards the user interface. The
7447 silc/ directory includes now the same user interface as before
7448 and it uses the new client library. Read lib/silcclient/README.
7449 Basicly, the client library performs everything else related
7450 to SILC except user interface handling. Also, configuration
7451 files are considered to be part of user interface and library
7452 does not handle them.
7454 This change also changed a lot of structures, function naming etc.
7455 Most important change was that SilcClientWindow object was
7456 renamed to SilcClientConnection in the client library. Created
7457 also new file lib/silcclient/ops.h. Also added new files
7458 silc/local_command.[ch] and silc/client_ops.[ch].
7460 All these changes were made to make it easier for user interface
7461 designers to create what ever user interface for the SILC client
7464 It is also expected that the server will be moved to lib
7465 directory as well and SILC Server Library will be created;
7466 sometimes in the future.
7468 * Removed Local commands from lib/silccore/silccommand.h as
7469 they are application specific and new client library does not
7470 handle any of those anymore.
7472 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7473 old client implementation in silc/.
7475 * Added support for callback functions in SILC_LOG_* macros.
7476 Application can now set its own callbacks that will be called
7477 instead of using the default functions that will always print
7478 the debug messages to stderr (or stdout). Also, debugging can
7479 now be disabled by setting silc_debug to FALSE and re-enabled by
7480 setting it to TRUE. Note, that logging will still work even
7481 if debugging is disabled.
7483 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7484 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7485 silc_log_reset_debug_callbacks.
7487 * To enable debugging in silc client one must give now -d
7488 option on command line.
7490 * Changed silc_schedule_init to automatically allocate task queues
7491 if they are not allocated before calling it.
7493 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Added GMP 3.1 into math library.
7497 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7500 a channel in SILC network. The packet is used by servers and
7501 routers to notify other routers that user has left a channel.
7502 This little feature was missing until now. Added the feature
7503 to protocol specification as well.
7505 Added functions: silc_server_send_remove_channel_user and
7506 silc_server_remove_channel_user into server.[ch].
7508 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7509 lib/silccore/silcpacket.h. However, they are not implemented
7512 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7514 * Fixed joining to a channel and sending channel messages
7515 between server and router. The channel message sending should
7516 now work inside a cell.
7518 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7520 * Fixed the private message sending between server and router.
7521 The private message sending should now work inside a cell.
7523 * Added silc_server_replace_id into server.[ch] to replace
7524 existing ID in the SILC network.
7526 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7527 and silc_idlist_replace_server_id into idlist.[ch] in server.
7529 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Fixed the server to server connections. Server can again now
7532 connect to router. Router to router connections probably does
7535 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * Added dynamic protocol registering support. Now protocols can
7538 registered and unregistered on the fly. Patch by cras.
7540 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7542 * Added lib/contrib directory to hold routines that some platforms
7543 don't have but are needed by SILC.
7545 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7546 into lin/contrib to provide getopt() and getopt_long() for
7547 those who don't have it.
7549 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7551 * Added AWAY command to client. When away message is set and
7552 client receives a private message packet the client automatically
7553 replies to the sender with the away message.
7555 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7556 bug seemed to be the cause of recent problems when compiling
7559 * Added version detection support to SKE protocol specification
7560 and added the new changes to the SKE implementation as well.
7561 There were other minor changes in the SKE protocol as well.
7563 Many changes in lib/silcske/silcske.[ch] and in
7564 lib/silcske/payload.[ch].
7566 * Added ^U functionality, clear input line. Patch from cras.
7568 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7570 * Mainly small bugfixes on core library. Fixed some debugging
7571 logging and buffer overflow in silclog.c.
7573 * Updated config.sub and config.guess on the distribution tree.
7575 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7577 * Added command lagging support in server. Client may execute
7578 commands now only once in two seconds.
7580 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * Optimized packet reception. MAC computation and checking is now
7583 also more optimized. A lot previously duplicated code is now
7584 used as generic by both client and server.
7586 * Fixed key pair generation in clientutil.c
7588 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7590 * Added into lib/silccore/silcbufutil.[ch] new function;
7591 silc_buffer_realloc.
7593 * Moved generic packet sending/encryption functions to
7594 lib/silccore/silcpacket.[ch] from client and server. Some
7595 rewriting of the functions.
7597 * Moved all generic packet reception/decryption functions to
7598 lib/silccore/silcpacket.[ch] from client and server. The
7599 packet processing is now much cleaner in both client and server.
7600 These were major changes in both client and server.
7602 * Created many common functions in server to do packet sending.
7603 Previously code were duplicated a lot, this has been removed
7606 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7608 * Rewrote major parts of the ID cache system. Don't know
7609 whether it is better now or not but at least the API is more
7612 * Major rewrite on ID cache stuff on client because of the ID
7613 cache API changes. Added idlist.c to client.
7615 * Also major rewrite on ID cache stuff on server as well.
7616 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7617 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7618 in hand, instead they are all put into the ID cache system now.
7619 All server_idlist_* routines uses ID cache now instead of
7620 traversing its own lists (those lists does not exist anymore).
7621 SilcIDList though still exists. Also, SilcXXXEntry's are
7624 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Finally made the SKE implementation compliant to the protocol
7627 specification. All mp integers are now binary encoded as
7628 opposed being HEX encoded.
7630 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7633 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7634 functions: silc_[encode/decode]_pem. Also added function
7635 silc_encode_pem_file to PEM encode with newlines ('\n') for
7638 * SILC public keys are now encoded either PEM or binary. Same
7639 option is for private keys as well. By default private keys
7640 are binary encoded and public keys PEM encoded. Silly HEX
7641 encoding were removed.
7643 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7644 function to create fingerprints.
7646 * Fixed a bug in SHA1; does not change the original data anymore.
7648 * Partly implemented INFO command on client and server side.
7649 Fixed CLEAR command. Changes to SERVER command; show current
7650 server(s) when giving command without arguments. Added
7651 VERSION command to client.
7653 * Added check to server that unregistered connections cannot
7654 execute commands (unless it is specificly allowed).
7656 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Fixed screen refresh.
7660 * Fixed channel joining bug from client. On some circumstances
7661 client tried to join to a channel it had already joined.
7663 * Added public key verification process into client's protocol.c.
7664 The client now verifies the public key from user and saves
7665 it into ~./silc/serverkeys/ directory.
7667 Added into: clientutil.[ch]: silc_client_verify_server_key.
7669 * Changed SKE protocol's silc_ske_initiator_finish function
7670 to accept callback function that verifies the received public
7671 key. Removed old silc_ske_verify_public_key function.
7673 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7675 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7676 silc_pkcs_private_key[_data]_set.
7678 * Made the password and public authentication more cleaner in
7679 server's protocol.c.
7681 * Removed historic and obsolete protocol `channel_auth' from
7682 both client and server.
7684 * Removed wrong way of sending command status messages from
7685 server to client in server's command.c. The old way violated
7686 protocol specification.
7688 Changes to silccore/silccommand.[ch]: removed
7689 silc_command_encode_status_payload -> not needed anymore,
7690 changed silc_command_encode_payload_va to accept extra
7691 argument on variable argument list. The argument type must
7692 now be provided to the function. Also, added new function:
7693 silc_command_encode_reply_payload_va which is same as
7694 normal command_encode_payload_va except command status type
7695 is provided as extra argument.
7697 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7699 * Added ~./silc directory handling. The directory includes the
7700 public and private keys for the client.
7702 Added silc_client_check_silc_dir, silc_client_create_identifier
7703 and silc_client_load_keys.
7705 * Implemented SILC protocol compliant public key. Added public
7706 and private key saving to and loading from files.
7708 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7709 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7710 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7711 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7712 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7714 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7715 silc_pkcs_load_[public/private]_key.
7717 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7719 * Added silc_server_get_route (route.[ch]) to get connection
7720 data for the fastest route for given ID.
7722 * Implemented INVITE command on client and server. The command
7723 were re-defined in the SILC Protocol Specification and the
7724 implementation now complies with the specification.
7726 * Implemented PING command on client and server.
7728 * Implemented NAMES command on client and server. The server side
7729 supports currently only normal server not router server yet.
7730 Some changes to NAMES definition in SILC protocol specification.
7732 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7734 * Implemented LEAVE command on client and server.
7736 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7737 again. This change was made to the protocol as well. Server
7738 should not violate the protocol specification anymore.
7740 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7742 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7743 was tested. SOCKS4 was not but should work anyway.
