1 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Created new branch silc_protocol_1_0_branch.
5 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
7 * Changed the silc_server_config_* routines to be SilcServer
8 independent. They are now officially application specific code
9 and not part of generic server implementation. Affected files
10 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
12 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
14 * Added automatic referencing of config context in the
15 silc_server_config_alloc, and automatic unreferencing in the
16 silc_server_config_destroy. Affected files are
17 silcd/serverconfig.[ch], silcd/silcd.c.
19 * Fixed the silc_log_quick handling in the logging routines.
20 It didn't log quickly when it was TRUE. Affected file is
21 lib/silcutil/silclog.c. Also the flush delay was set even
22 if it was 0 in config file. Affected file is
25 * Added support for changing key pair of the server in rehash.
26 Affected file silcd/server.c.
28 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
30 * Fixed the TOPIC_SET notify to not cras. It changed the topic
31 too early, before getting the channel entry. Affected file
32 is silcd/packet_receive.c.
34 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
36 * Added functions silc_server_config_[ref/unref], these are used
37 to prevent that the config object is destroyed.
39 No longer directly affect global variables silc_log_quick and
40 silc_log_delay, they are first cached inside the config object
41 and then applied with silc_server_config_setlogfiles().
43 silc_server_config_set_defaults() is now internal to
44 serverconfig.c, there are no reasons to show this internal stuff
47 Affected files are silcd/serverconfig.[ch].
49 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
50 fprintf's to stderr, since some code may be executed again after
51 the server went into the background. Affected files are
54 * Added rehash support. Added function silc_server_rehash() that
55 will perform all the basic tasks of the rehashing procedure.
57 * Added command line option `-x, --hexdump'. This will enable the
58 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
59 The option `--hexdump' implies `--debug'.
61 * Fixed a bad bug in the logging APIs (silcutil library) where
62 the application would crash after calling silc_log_reset_all().
64 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Fixed the KICKED notify handling in client library to
67 correctly remove the channel and all entries from the
68 channel when I was kicked. This bug crashed the client.
70 Fixed yet another but in KICKED notify handling to remove
71 the kicked client correctly from the channel.
73 Affected file is lib/silcclient/client_notify.c.
75 * Fixed a minor bug in looking up correct client entry
76 in KICKED notify in server. Affected file is
77 silcd/packet_receive.c.
79 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
80 sources correctly to distribution. Fixes --with-gmp option.
82 * Removed the manual rehashing from ID Cache, and changed it
83 to use the SILC Hash Table's auto rehash feature. Affected
84 file is lib/silccore/silcidcache.c.
86 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
88 * Fixed a bug in the silc_client_nickname_format function that
89 handles the multiple same nickname formatting. Two clients
90 with same nickname caused problems after the first one left
91 and rejoined. It didn't format the nickname correctly.
92 Affected file is lib/silcclient/idlist.c.
94 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
96 * Don't change the topic if olod topic is same as new one.
97 Affected file is silcd/packet_receive.c.
99 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Added cross-reference support to the SILC Documentation
102 generator. All types across all HTML files are now cross-
103 referenced. Affected files util/robodoc/generator.c and
104 scripts/silcdoc/silcdoc.
106 * Added file lib/silcutil/silctypes.h to include all the
107 arithmetic type definitions and some macros. Removed
108 includes/bitmove.h and moved macros to silctypes.h.
110 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
112 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
114 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
116 * Added `type' argument to silc_id_payload_parse_id function which
117 now returns the type of the ID to the sent pointer. Affected
118 file is lib/silccore/silcid.[ch].
120 * Added check for CMODE_CHANGE notify type that mode change is
121 allowed by the sender. Affected file silcd/packet_receive.c.
123 * Added check for CUMODE_CHANGE notify type that mode change is
124 allowed by the sender. Affected file silcd/packet_receive.c.
125 Added the ID type as CUMODE_CHANGE notify type as argument
126 to the `notify' client operation. Affected files are
127 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
129 * Added function silc_client_add_server to the client library.
130 Added support for resolving also channel and server info when
131 received unknown entity in notify packet. Affected files are
132 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
134 * Added function silc_command_get_status to return the command
135 status from the command reply's argument payload. Affected files
136 are lib/silccore/silccommand.[ch].
138 * Added check for KICKED notify type that the kicking is
139 allowed by the client. Affected file silcd/packet_receive.c.
141 * Created function silc_get_input which can be used to get input
142 (echo on or off) from user on command line. Affected files are
143 lib/silcutil/silcutil.[ch].
145 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
147 * Optimized silc_server_packet_relay_to_channel function.
148 Added new function silc_channel_message_payload_encrypt which
149 can be called directly if channel message payload needs to
150 be encrypted and is already encoded (no need to call _encode
151 function). Packet relaying is now done by router without any
152 extra memory allocations. Affected files are
153 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
156 * Fixed the INVITE notify handling. It took wrong arguments
157 as invite list and invite delete. Affected file is
158 silcd/packet_receive.c.
160 * Added check for TOPIC_SET notify type that the topic change is
161 allowed by the client. Affected file silcd/packet_receive.c.
163 * Added check for INVITE notify type that inviting is allowed by
164 the client. Affected file silcd/packet_receive.c.
166 * Changed the silc_server_client_on_channel to return the
167 SilcChannelClientEntry as well. Moved the function
168 silc_server_check_cmode_rights to server_util.[ch].
169 Affected files are silcd/server_util.[ch], silcd/command.c.
171 * Added function silc_server_check_umode_rights to check whether
172 changing client's user mode is allowed. Added check for
173 UMODE_CHANGE notify type that the umode change is allowed
174 by the client. Affected files are silcd/server_util.[ch],
175 silcd/packet_receive.c and silcd/command.c.
177 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
179 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
180 ID length. It ignored that ID can be IPv6 based as well.
181 Affected file lib/silccore/silcpacket.h.
183 * Fixed the silc_id_id2str and silc_id_str2id to take the
184 IPv6 address offset's into consideration. Affecte file is
185 lib/silccore/silcid.c.
187 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
189 * Fixed the internal Unix scheduler functions to check for
190 NULL context they may receive. The affected file is
191 lib/silcutil/unix/silcunixschedule.c.
193 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
195 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
196 can specify different directory with --home command line
197 parameter. Affected files irssi/src/silc/core/client_ops.c,
200 * SILC-specific commands aren't now executed if the active server
201 isn't of SILC-type, so there won't be problems with having
202 IRC and SILC protocol support in same client. Affected files
203 irssi/src/silc/core/silc-channels.c, silc-servers.c,
206 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
208 * Improved the signal support in SILC Schedule. Added new
209 function silc_schedule_signal_call which is used by application
210 to mark a signal to be called. It is now safe to perform
211 any kind of tasks in signal callbacks since it is guaranteed
212 that the application specified signal callback is called
213 after the signal is over. Affected files are
214 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
216 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
218 * Added `name' field to SilcChannelPrivateKey to represent
219 application given name for the key. Moved also the context from
220 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
221 Added the `name' argument also to the function
222 silc_client_add_channel_private_key.
224 Added function silc_client_current_channel_private_key to set the
225 current channel private key in use.
227 Added "change" command to KEY command which can be used to change
228 the current channel private key. Bound the command also to
231 Also affected files lib/silcclient/client_channel.c,
232 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
234 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
236 * Added silc_rng_get_byte_fast function in to the
237 lib/silccrypt/silcrng.[ch].
239 * Changed the interface of silc_packet_assemble and the
240 silc_packet_send_prepare. If silc_packet_assmble is now
241 called the application does not call silc_packet_send_prepare
242 because the library will call it automatically. These
243 interfaces now also return a reference to the outgoing buffer
244 which includes the assembled packet, which the application can
245 use to encrypt the packet.
247 Affected files are lib/silccore/silcpacket.[ch],
248 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
249 silcd/packet_send.c, server_backup.c and packet_receive.c.
251 * Fixed a packet sending bug on very high load, where outgoing
252 packet queue wasn't handled correctly and packets got corrupted.
253 Affected files are lib/silcutil/*/silc*sockconn.c,
254 lib/silcclient/client.c and silcd/server.c.
256 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
258 * Added macro SILC_PACKET_DATALEN which can be used during
259 packet assembling to check whether the data to be added to
260 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
261 len is truncated until it fits it.
263 Added checks for maximum length of channel message payload and
264 private message payload also.
266 Added checks for maximum packet length in server and in
269 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
270 lib/silcclient/client.c, lib/silccore/silcchannel.c and
271 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
272 lib/silcclient/client_prvmsg.c.
274 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
276 * Added silc_server_packet_queue_purge call to the
277 silc_server_disconnect_remote to assure that all data in the
278 queue before disconnecting is sent to the network. Affected
281 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
283 * Added the deleting of server's own ID cache entry to the
284 silc_server_free function. Free also everything else that
285 has been allocated in silc_server_init. The affected file
288 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
290 * Added functions silc_parse_version_string, silc_version_to_num,
291 and silc_ske_parse_version to parse SILC protocol style version
292 strings. Affected files lib/silcutil/silcutil.[ch] and
293 lib/silcske/silcske.[ch].
295 * Added new configuration params: version_protocol, version_software
296 and version_software_vendor to specify what version the remote
297 host must at least be to be able to connect to server. The vendor
298 string can be regex matched too. Added new function
299 silc_server_connection_allowed to check maximum number of allowed
300 connections, and allowed versions for incoming connections.
301 Affected files are silcd/server.c, server_util.[ch] and
304 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
306 * Added preliminary support for signals in scheduler. The
307 signals we care about are now blocked always when the scheduler
308 is locked. This way we can synchronise the use of signal with
309 scheduler. It is guaranteed that when signal occurs the scheduler
310 is not locked, and thus new tasks can be safely added to the
313 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
314 to silc_schedule_internal_init and silc_schedule_internal_uninit.
315 Added new platform specific routines
316 silc_schedule_internal_signals_[un]block and
317 silc_schedule_internal_signal_[un]register.
319 Added new functions to SILC Schedule API:
320 silc_schedule_signal_[un]register. Each signal that application
321 is going to use should be registered to the scheduler.
323 Affected files are lib/silcutil/silcschedule.[ch],
324 lib/silcutil/*/silc*schedule.c.
326 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
328 * Check for unauthenticated client and server in the
329 silc_server_new_client and silc_server_new_server functions.
330 Affected file silcd/packet_receive.c.
332 * Added function silc_string_is_ascii to check whether given
333 string is 7-bit ASCII string. Affected files are
334 lib/silcutil/silcutil.[ch].
336 * Added function silc_id_is_valid_server_id into the
337 silcd/serverid.c and added checking for valid Server ID's in
338 silc_server_new_server. The Server ID must always be based
339 on the server's public IP address.
341 * Added logging of DISCONNECT packet message in the server.
342 Affected file silcd/server.c.
344 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
346 * Changed all library interfaces that use Global RNG to also
347 accept SilcRng as argument. Affected files are
348 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
349 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
350 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
351 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
354 * Added function silc_pkcs_generate_key to the
355 lib/silccrypt/silcpkcs.[ch] for applications so that they
356 don't need to do pkcs->pkcs->init calls anymore.
358 * Remove SilcSocketConnection from the SFTP API since it really
359 wasn't needed there. The application has the information
360 saved in its contexts anyway and the SFTP layer doesn't need
361 know about it. Affected files lib/silcsft/silcsftp.h and
362 lib/silcsftp/sftp_[server/client].c.
364 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
365 The SilcSimContext is not SilcSim.
367 * Fixed possible buffer overflows in silc_id_render in the
368 lib/silcutil/silcutil.c.
370 * On EPOC the global crypto module lists are not used at all
371 in the crypto library. Added support for using the constant
372 algorithm list on EPOC. Affected files are
373 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
376 * Fixed the handling of third parameter of KICKED notify, since
377 it was mistakenly updated to SILC Protocol 1.0 even though it
378 is to be included in 1.1. Since it is not in 1.0 it is not
379 mandatory, and this fix now handles it only if it is provided,
380 and it is not error if it is not provided. Affected file
381 lib/silcclient/client_notify.c.
383 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
385 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
386 client. Affected file irssi/src/silc/core/client_ops.c.
388 * Merged with Irssi 0.8.4 from irssi.org CVS.
390 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Check for valid socket connection in client entries before
393 sending any messages. Fixes a crash, but doesn't fix some
394 other underlaying bug that is lurking there. Affected
395 file silcd/packet_send.c.
397 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
399 * $usermode, $cumode and $cumode_space expandos shouldn't do
400 anything with non-SILC server records. Affected file
401 irssi/src/silc/core/silc-expandos.c
403 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
405 * Fixed the silc_net_check_[host/local]_by_sock to support
406 IPv6 bound sockets as well. Now they can return IPv6 addresses
407 as well. Affected file lib/silcutil/silcnet.c.
409 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
410 Affected lib/silcutil/unix/silcunixnet.c.
412 * Fixed ID rendering (at least on some platforms, not NetBSD)
413 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
415 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
417 * Added silc_hash_public_key and silc_hash_public_key_compare
418 functions to be used with SilcHashTable. They can be used to
419 hash public keys and compare public keys in hash table. Affected
420 file lib/silcutil/silcutil.[ch].
422 * Added support for specifying multiple public keys for Client
423 connection section in server configuration file. This makes it
424 possible to accept multiple public keys from same host, or to
425 make a section that accepts any incoming host, and have the
426 accepted public keys listed in the section.
428 Added functions silc_sever_[find/get]_public_key, added the
429 support for this actually to all connection sections but only
430 the Client section is currently allowed to specify multiple
433 Affected files are silcd/server.c, server_internal.h,
434 command.c, protocol.c, server_util.[ch], packet_receive.c.
436 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
438 * Merged Irssi 0.8.2 from irssi.org CVS.
440 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
442 * If silc_debug is TRUE, also output standard logging messages
443 to stderr with the debug output.
445 Made silc_log_reset_all() flushing all channels before returning.
446 Also fixed some documentation typos.
448 Affected files are lib/silcutil/silclog.[ch].
450 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
452 * Fixed the server to check correctly the amount of connections
453 from single host, by checking also the type of the connection.
454 Fixed also the comparison of number of connections and number
455 of allowed connections. Affected files are silcd/server.c,
458 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
460 * Fixed the USERS command reply to save the user's mode on the
461 channel as well. Fixed JOIN command reply to check whether a
462 client is on channel already and not join it twice. Affected
463 file lib/silcclient/command_reply.c.
465 * Added new file silc-expandos.c into irssi/silc/core/ to return
466 various stuff for various signal for the statusbar etc. updating.
467 Now Irssi SILC client prints channel user modes etc. on the
470 * The user mode (like server/router operator changes) is now shown
471 on the Irssi SILC client's statusbar. The affected files are
472 irssi/src/silc/core/client_ops.c, silc-expandos.c.
474 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
476 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
477 to SILC_SCHEDULE_[UN]LOCK macros.
479 * Added more error printing to logs in server code. Affected
480 files silcd/server.c and silcd/protocol.c.
482 * Fixed -S option parsing in Irssi SILC Client. Affected file
483 irssi/src/silc/core/silc-core.c.
485 * Added silc_buffer_alloc_size function. Affected file is
486 lib/silcutil/silcbuffer.h.
488 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
490 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
491 constants. Affected files in
492 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
495 * Changed the internal SFTP Memory FS table to const. Affected
496 file lib/silcsftp/sftp_fs_memory.c.
498 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
500 * Fixed the buffer formatting and unformatting routines to
501 check the size of 64 bits types with sizeof(). Affected
502 file is lib/silcutil/silcbuffmt.c.
504 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Removed 0.6.x backwards support.
508 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
510 * Changed all integer type names:
511 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
512 to avoid collisions with other libraries using same type names
515 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
517 * Added `prefer_ipv6' argument to the functions
518 silc_net_gethostbyname[_async]. If it is TRUE it will return
519 IPv6 address over IPv4. If FALSE IPv4 address is returned
520 even if IPv6 address was found. Affected files
521 lib/silcutil/silcnet.[ch].
523 * Added support silc_net_create_connection[_async] to fallback
524 to IPv4 address if IPv6 address could not be used (like if
525 it doesn't work on a specific system). Affected file in
526 lib/silcutil/unix/silcunixnet.c.

537 application does not need to define them. Affected file
538 includes/silcincludes.h.
540 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
541 old name went against naming convention. Applications now
542 include "silcclient.h" instead of "clientlibincludes.h".
543 Removed includes/clientlibincludes.h, it is redundant now.
545 * Renamed includes/version.h to silcversion.h.
547 * Added really preliminary support for OS/2 into the util
548 library. Only thread & mutex API is implemented, others
549 are still to be implemented. Created the lib/silcutil/os2/
550 directory. Created also file includes/silcos2.h.
552 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

600 Affected file lib/silcclient/client.c.
602 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * ROBOdoc documented the lib/silcske/silcske.h, and improved
605 the SKE interface a bit.
607 * Fixed padding problem in PKCS#1. The padding was not actually
608 random since the random number generator was used incorrectly.
609 This security bug affects only when encrypting with PKCS#1, and
610 it is not currently used at all in SILC. SILC only use signing
611 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
613 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

631 if connection authentication protocol is not based in public
634 Renamed all SilcServerConfigSection* to SilcServerConfig*
635 to have a bit shorter names.
637 Affected files silcd/serverconfig.[ch], server.[ch], and

677 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
679 * Added new configuration options and blocks:
680 keepalive_secs, reconnect_count, reconnect_interval,
681 reconnect_interval_max, reconnect_keep_trying and
682 require_reverser_lookup. Added ConnectionParam block, and
683 implemented the connection parameters when connecting as
684 initiator and when accepting connections as responder.

687 whether given configuration value has been given already.
689 Affected files silcd/serverconfig.[c], server.[c].
691 * Splitted the doc/example_silcd.conf.in. Separated the crypto
692 algorithm parts and created new file silcalgs.conf, that
693 is now included from the example_silcd.conf.in.
695 * Optimized the silc_server_connect_to_router_second to take
696 the connection configuration object from the SilcServerConnection
697 object instead of finding it during the connecting phase.
698 Added the configuration object to SilcServerConnection struct.
699 Affected files silcd/server_internal.h, server.c.

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

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

808 SILC_LOG_WARNING to give out Warning and not Error. Affected
809 file lib/silcutil/silclog.c.
811 * Fixed the channel message payload decryption in the function
812 silc_channel_message_payload_decrypt to not modify the original
813 buffer before it is verified that the message decrypted
814 correctly. Otherwise, next time it is called with correct
815 channel key it won't encrypt since the payload is corrupted.
816 Affected file lib/silccore/silcchannel.c.
818 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

855 silc_client_replace_channel_id, and removed functions
856 silc_client_new_channel_id and silc_idlist_get_channel_by_id
859 * Added cross reference of the joined channels to the
860 SilcClientEntry, and changed the SilcChannelEntry's
861 users list to SilcHashTable. The affected files are
862 lib/silcclient/idlist.[ch].
864 * Fixed a bug in hash table tarversing. While the hash table
865 is traversed with SilcHashTableList the table must not be
866 rehashed. It is now guaranteed that auto rehashable tables
867 are not rehashed while tarversing the list. Also defined that
868 silc_hash_table_rehash must not be called while tarversing
869 the table. Added function silc_hash_table_list_reset that must
870 be called after the tarversing is over. The affected files are
871 lib/silcutil/silchashtable.[ch].
873 * Changed all hash table traversing to call the new
874 silc_hash_table_list_reset in server and in client library.
876 * Added function silc_client_on_channel to return the
877 SilcChannelUser entry if the specified client entry is joined
878 on the specified channel. This is exported to application as
879 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
881 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
883 * Fixed founder regaining problem with JOIN command on normal
884 server. The notify for mode change must be sent always and
885 not only if !cmd->pending. Affected file silcd/command.c.
887 * Fixed the WHOWAS command's reply sending to support the
888 lists correctly. Affected file silcd/command.c.
890 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
892 * When sending JOIN command to router for processing the
893 sender's old command identifier was not saved back to the
894 sender's command context, fixed now. The affected file is
897 * Create the key in JOIN command of the router did not return
898 the channel key, added check for this. Affected file is
901 * Fixed a channel ID update bug in JOIN command reply. Do
902 not directly upgrade the ID but call the function
903 silc_idlist_replace_channel_id if the ID was changed.
904 Affected file silcd/command_reply.c.
906 * Fixed memory leaks from command calling if it would fail.
907 Affected file silcd/command.c.

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

970 * Added server & router operator statistics updating. Affected
971 file silcd/packet_receive.c and silcd/command.c.
973 * Fixed the SERVER_SIGNOFF notify handling on normal server
974 not to save the history information for clients. Same was
975 fixed earlier in remove_clients_by_server function, but not
976 here. Affected file silcd/packet_receive.c.
978 * Raised the default connection-retry count from 4 to 7 in
979 server. Affected file silcd/server.h.
981 * Cancel any possible reconnect timeouts when we start the
982 key exchange. Affected file silcd/server.c.
984 * Do not reconnect on connection failure when SCONNECT was

989 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
991 * Fixed the NICK command to always give the unformatted
992 nickname to the one giving the NICK command. If unformatted
993 nickname is cached already it will be formatted and the
994 local entry will always get the unformatted nickname.
995 Affected file lib/silcclient/idlist.c.
997 * Fixed some double frees from client library commands.
998 Affected file is lib/silcclient/command.c.
1000 * Fixed CUMODE command in server to assure that no one can
1001 change founder's mode than the founder itself, there was a
1002 little bug. Affected file silcd/command.c.
1004 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1006 * Removed the SilcClientCommandDestructor from the client
1007 libary, it is not needed anymore. Affected files are
1008 lib/silcclient/silcapi.h, command[_reply].[ch],
1009 client_notify, idlist.c.
1011 * Fixed GETKEY command to first resolve client, and then
1012 resolve the server only if the client was not found, instead
1013 of resolving both at the same time. Affected file is
1014 lib/silcclient/command.c.
1016 * Added silc_client_start_key_exchange_cb and lookup the
1017 remote hostname and IP address before starting the key
1018 exchange with server. The affected file is
1019 lib/silcclient/client.c.
1021 * The server's public key is now saved using the IP address
1022 of the server and not the servername for the filename.
1023 The hostname public key filename is checked as an fall back
1024 method if the IP address based filename is not found.
1026 Fixed the GETKEY command to save the fetched server key
1027 in correct filename.
1029 Print the remote server's hostname now when new key is
1030 received during connection process. Affected file is
1031 irssi/src/silc/core/client_ops.c.
1033 * Return always our own public key to the client if it asks
1034 for it with GETKEY command. Affected file silcd/command.c.
1036 * Removed the use_auto_addr variable from default config
1037 file since it was in wrong section. Affected file is
1040 * Fixed TOPIC_CHANGE notification to not route it when it
1041 was sent using silc_server_send_notify_to_channel function.
1042 Affected file silcd/command.c.
1044 * Fixed silc_server_send_notify_kicked to send the kicker's
1045 Client ID also, it was missing. Affected files are
1046 silcd/command.c, silcd/packet_send.[ch].
1048 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1050 * Do not save client history information in SERVER_SIGNOFF.
1051 Fixes the bug in normal server that it does not detect
1052 the client becoming valid after the server becomes back
1053 online. Affected file silcd/server_util.c.
1055 * Added `sock_error' field into the SilcSocketConnection
1056 context. When error occurs during socket operation (read
1057 or write) the error is saved. Added also new function
1058 silc_socket_get_error to return human readable socket error
1059 message. Affected files are lib/silcutil/silcsockconn.[ch],
1060 lib/silcutil/unix/silcunixsockconn.c, and
1061 lib/silcutil/win32/silcwin32sockconn.c.
1063 * The server now prints the socket error message in the
1064 signoff for client. Affected file silcd/server.c.
1066 * Fixed the `created' channel information sending from router
1067 to server in JOIN command. Checks now whether the channel
1068 really was created or not and set it according that.
1070 Fixed the JOIN command to use the client entry's current
1071 ID during the joining procedure instead of the one it sent
1072 in the command (it is checked though), since it can change
1073 between the packet processing and command processing, and
1074 would just case unnecessary pain in the client end. Affected
1075 file silcd/command.c.
1077 * Fixed a channel key payload sending to use correct channel
1078 ID when the server was forced to change the channel's ID by
1079 router. Router sent the key payload with the old Channel ID.
1080 Affected file silcd/packet_receive.c.
1082 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1084 * Call silc_server_save_channel_key only if the key payload
1085 was provided in the JOIN command's command reply. Affected
1086 file silcd/command_reply.c.
1088 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * Fixed silc_mp_sizeinbase to return the value correctly with
1091 MPI. Affected file lib/silcmath/mp_mpi.c.
1093 * Fixed the stop_server signal to correctly stop the scheduler
1094 and gracefully stop the server when SIGTERM or SIGINT signals
1095 are received. Affected file silcd/silcd.c.
1097 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1099 * Simple handling of TERM and HUP signals. Also added some log
1100 flushing call around. Affected file is
1103 * Fixed small bugs in silclog.c. Now buffering output will take
1104 effect after 10 seconds since startup: This will ensure that
1105 no important startup messages are lost. Also output redirection
1106 will preserve original format ([Date] [Type] message).
1107 Affected file is lib/silcutil/silclog.c.
1109 * Added two options to the config file, in the logging section:
1110 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1111 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1113 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1115 * Do not print the warning about log files not being initialized
1116 more than once to avoid excess logging. Affected file is
1117 lib/silcutil/silclog.c.
1119 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1120 the SIM copying in make install in Makefile.am.pre.
1122 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1124 * Rewritten silclog APIs. Globally interesting changes follows:
1125 silc_log_set_files() changed to silc_log_set_file().
1126 silc_log_set_callbacks() changed to silc_log_set_callback().
1127 ROBOdoc documented silclog header file.
1128 SilcLogCb now returns bool to wether inihibit the default
1129 handler or not (to keep the old behaviour return always TRUE).
1130 The new APIs should also fix the problem of the
1131 silcd_error.log file that was written in the current directory.
1134 Log files streams will remain opened after silc_log_set_file()
1135 call, means less CPU usage notably on high traffic servers.
1136 File streams are now full buffered, and flushed to the disk
1137 every 5 minutes, lesses HD activity and CPU usage.
1138 Messages can be redirected, allowing admins to configure
1139 one single logfile for all server messages.
1140 the silc_log_quick global variable to activate fast-logging.
1141 Affected files lib/silcutil/silclog.[ch]
1143 * Changed some code to conform new silclog APIs. Affected
1144 files are doc/example_silcd.conf.in, silcd/server.c
1145 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1148 * Fixed a memory leak that could occur in some situations.
1149 Affected file silcd/serverconfig.c.
1151 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1153 * Added the silc_client_del_client to remove the client from
1154 all channels as well. Affected file lib/silcclient/idlist.c.
1156 * Fixed the client library to correctly remove the client
1157 from all channels when the client entry is being destroyed.
1158 Affected file lib/silcclient/client_notify.c, command.c.
1160 * Added auto-nicking support to the client library. If the
1161 applicatio now sets client->nickname it will be sent to the
1162 server after connecting by the library. This way for example
1163 SILCNICK (or IRCNICK) environment variables will have effect
1164 and always change the nickname automatically to whatever
1165 it is wanted. Affected file lib/silcclient/client.[ch].
1167 * Renamed silc_server_command_bad_chars to the
1168 silc_server_name_bad_chars and moved it to the
1169 silcd/server_util.[ch]. Added also new function
1170 silc_server_name_modify_bad to return nickname that
1171 includes bad characters as new nickname without those
1172 bad characters. This check and modify is now used in
1173 silc_server_new_client when the username is initially set
1174 as nickname, so it must be checked to be valid nickname.
1175 Affected file silcd/packet_receive.c.
1177 * The nickname length is now taken from the packet for real
1178 and not trusted to strlen() since it clearly can return
1179 wrong length for nickname including bad characters. This
1180 also applies to channel names. Affected file silcd/command.c.
1182 * Removed the lib/silcsilm/modules directory. Modules are now
1183 compiled into the lib/silcsim. Fixed the copying of the
1184 modules to follow symbolic links in Makefile.am.pre.
1186 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1188 * Fixed silc_string_regexify list creation. Fixes bugs with
1189 BAN and INVITE commands in server. The affected file is
1190 lib/silcutil/unix/silcunixutil.c.
1192 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1194 * Removed the command destructor entirely from the server's
1195 command and command reply routines. It is not needed, and
1196 its usage was buggy and caused crashes. Affected files are
1197 silcd/command[_reply].[ch].
1199 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * Cancel protocol and NULL sock->protocol if timeout
1202 occurred during protocol. Affected file silcd/server.c.
1204 * Cancel protocol timeouts always before calling the final
1205 callback, to assure that after final callback is called
1206 no other state will be called for the protocol anymore.
1207 Affected file silcd/protocol.c.
1209 * Print error log if incoming connection configuration could
1210 not be found. Affected file silcd/server.c.
1212 * Fixed JOIN command to correctly save the founder mode
1213 to the client on normal SILC server, when the channel
1214 was created by the router. Affected file silcd/command.c.
1216 * Fixed LIST command (hopefully) to send correct reply
1217 packets. Affected file silcd/command.c.
1219 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * The silc_packet_receive_process now returns FALSE if the
1222 read data was invalid packet, and TRUE if it was ok.
1224 The server now checks that if unauthenticated connection
1225 sends data and its processing fails the server will close
1226 the connection since it could be a malicious flooder.
1228 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1230 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * Make sure the warning about error opening a log file is
1233 printed only once and not everytime it fails (produces
1234 too much useless log). Affected file lib/silcutil/silclog.c.
1236 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1238 * Made the silc_server_daemonise() function more readable.
1239 Affected file silcd/server.c.
1241 * Pid file is now optional, the user may comment it out from
1242 the config file. Removed define SILC_SERVER_PID_FILE, we
1243 don't need a default any longer. Affected file
1244 configure.in.pre, lib/Makefile.am.pre.
1246 * Make some use of the pid file. The server now dies at startup
1247 if it detects a valid pid file on his path. The server would
1248 die anyway in this circumstance, because of the bind() failure.
1249 Affected file silcd/silcd.c.
1251 * No longer compiling lib/dotconf.
1253 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1255 * Fixed JOIN command parsing not to crash. Affected file
1256 lib/silcclient/command.c.
1258 * Fied the NICK_CHANGE notify to add the new client entry
1259 even it is resolved. This removes an <[unknown]> nick
1260 thingy bug in the client. Affected file is
1261 lib/silcclient/client_notify.c.
1263 * Do not try to allocate 0 bytes (efence does not like it)
1264 in lib/silccore/silccomand.c when encoding payload.
1266 * Do not take IRCNICK as nickname in Irssi SILC client since
1267 it is not possible to set nickname before hand connecting
1268 the server (TODO has an entry about adding auto-nicking
1271 * Changed the silc_server_command_pending to check whether
1272 there already exists an pending entry with the specified
1273 command, command identifier and pending callback. This is
1274 to fix IDENTIFY and WHOIS related crashes that may register
1275 multiple pending commands with same identifier. Affected
1276 file silcd/command.c.
1278 * Fixed the server to reconnect to the router even if it
1279 was already reconnecting and EOF was received. This to
1280 fix a possibility that the server wouldn't ever try to
1281 auto-reconnect to the router. Affected file silcd/server.c.
1283 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Fixed the server's password authentication to use the
1286 length of the locally saved password, and not the one
1287 sent in the packet. Affected file silcd/protocol.c.
1289 * Fixed same password authentication problem in the
1290 Authentication Payload handling routines in
1291 lib/silccore/silcauth.c.
1293 * Yet another password authentication problem fixed with
1294 channel password handling in silcd/command.c.
1296 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * If first character of string in silc_parse_userfqdn is '@'
1299 then do not parse it. Affected file is
1300 lib/silcutil/silcutil.c.
1302 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Fixed minor bug in IDENTIFY command reply sending, which
1305 caused various weird problems during JOIN when it was
1306 resolving names for users. Affected file silcd/command.c.
1308 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Fixed the IDENTIFY command reply sending to chech better valid
1311 clients. It was possible to send incomplete list of replies.
1312 Affected file silcd/command.c.
1314 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Added silc_client_command[s]_[un]register functions now to
1317 dynamically register the commands in client library. Removed
1318 the static table of commands. This allows the client library
1319 to call commands without causing the application to know about
1320 what commands library has called.
1322 Removed the INFO command reply kludge to detect when the command
1323 was called by library. Now library use its own command reply
1324 function for INFO command.
1326 Added function silc_client_command_call to call a command.
1327 Application can use it to call command, not access the structure
1330 Now all commands that are sent by the client library (not
1331 explicitly sent by application) use own command reply functions.
1333 Affected files around lib/silcclient/ and in
1334 irssi/src/silc/core/.
1336 * Fixed the WHOIS command reply sending to chech better valid
1337 clients. It was possible to send incomplete list of replies.
1339 Fixed the WHOIS and IDENTIFY to send the request to router
1340 if normal server did not do it and did not find any results.
1342 Affected file silcd/command.c.
1344 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Moved the internal data from SilcClient context into its
1347 own file, not accesible to application. Affected files
1348 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1349 and other files in client library.
1351 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1353 * Added doc/examples installation target in Makefile.am.pre.
1356 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1359 commands the found client entry will be removed from the
1360 cache, after notifying application about the error. Affected
1361 file lib/silcclient/command_reply.c.
1363 * Changed the /MSG to check for exact nickname user gave, and
1364 not let `nick' match `nick@host' if it is only one found. Now,
1365 user must type the exact nickname (like nick@host2) even if
1366 there are no more than one same nicks found. This is to avoid
1367 a possibility of sending nickname to wrong nickname since
1368 `nick' could match `nick@host'. Affected file is
1369 irssi/src/core/silc-servers.c.
1371 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Do not print "you are now server operator" or similar when
1374 giving /away command. Affected files are
1375 irssi/src/silc/core/client_ops.c, silc-servers.h.
1377 * Made the silc_server_command_pending_error_check to send
1378 the same command reply payload it received back to the
1379 original sender of the command. This way all arguments
1380 that was received by the server will be received by the
1381 client too. Affected file silcd/command.c.
1383 * Added the silc_idcache_add to return the created cache entry
1384 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1386 * Add global clients to expire if they are not on any channel.
1387 This is because normal server will never know if they signoff
1388 if they are not on any channel. The cache expiry will take
1389 case of these entries. This is done by normal servers only.
1390 The affected files are silcd/command_reply.c,
1391 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1393 * If server receives invalid ID notification for WHOIS or
1394 IDENTIFY and the ID exists in the lists, it is removed.
1395 Affected file silcd/command_reply.c.
1397 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1398 in client then client entry that it matches is searched and
1399 the nickname is printed on the screen for user. Affected
1400 file irssi/src/silc/core/client_ops.c.
1402 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Use cache entry expire time in the LIST command reply to
1405 purge old entries from the cache after the LIST command
1406 reply has been received. This way we don't have non-existent
1407 entries in the cache for too long. Affected file is
1408 silcd/command_reply.c.
1410 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * If we are normal server, and we've not resolved client info
1413 in WHOIS or IDENTIFY from router, and it is global client,
1414 we'll check whether it is on some channel. If it is not
1415 then we cannot be sure about its validity and will resolve it
1416 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1417 file silcd/command.c.
1419 * Search channel by name (if possible) rather than by ID
1420 in IDENTIFY command's command reply. Affected file is
1421 silcd/command_reply.c.
1423 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1426 Updated specs and implemented it. Affected file silcd/command.c,
1427 silcd/packet_send.c and silcd/packet_receive.c.
1429 * Implemented the <founder auth> payload handling in the JOIN
1430 command. If provided all conditions for channel joining
1431 except requirement to provide correct passphrase can be
1432 overrided by the channel founder. Updated the protocol specs.
1433 Affected file silcd/command.c.
1435 Added support for founder auth in JOIN command in client
1436 library. Fixed the parsing of the JOIN command now to support
1437 all options as they should be. The affected file is
1438 lib/silcclient/command.c.
1440 * Optimized the WHOIS and IDENTIFY commands to send the request
1441 to router only if it includes nicknames or other names. If
1442 they include only IDs then check the local cache first before
1443 routing. Affected file is silcd/command.c.
1445 * Added channels topic announcements. Affected file is
1446 silcd/packet_receive.c and silcd/server.c.
1448 * Fixed the silc_server_send_notify_topic_set to really destine
1449 the packet to channel. Affected file silcd/packet_send.c.
1451 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1452 library. Affected file lib/silcclient/client_notify.c.
1454 * Added UMODE announcements. Affected file silcd/server.c.
1456 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Memory leak fixes in:
1460 lib/silcutil/silcsockconn.c
1461 lib/silcske/silcske.c
1462 lib/silcske/groups.c
1464 lib/silccrypt/silcpkcs.c
1465 lib/silccore/silccommand.c
1466 lib/silccore/silcidcache.c
1471 * ROBOdoc documented the lib/silcske/groups.h file and a
1472 bit changed the interface for better.
1474 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1476 * Update the client entry context in the ID cache after
1477 nick change. Affected file lib/silcclient/command.c.
1478 Fixes the CUMODE command when regaining founder privileges,
1479 and a little WHOIS problem.
1481 * Fixed silc_net_gethostbyname to correctly call the
1482 inet_ntop. Affected file lib/silcutil/silcnet.c.
1484 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1486 * Added IPv6 support checking to the configure.in.pre, added
1487 also --enable-ipv6 option to override the check. Affected
1488 file configure.in.pre.
1490 * The silc_thread_create now calls the start function
1491 directly if threads support is not compiled in. Removes
1492 ugly #ifdef's from generic code. Affected files are
1493 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1495 * Added silc_net_gethostby[name/addr]_async to asynchronously
1496 resolve. Affected files are lib/silcutil/silcnet.[ch].
1498 * Added support for rendering IPv6 based server, client and
1499 channel IDs. Affected file lib/silcutil/silcutil.c.
1501 * Added support for creating IPv6 based server IDs. Affected
1502 file is silcd/serverid.c.
1504 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1506 * Added silc_net_gethostby[addr/name] into the
1507 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1508 routines. Added silc_net_is_ip[4/6]. Affected file is
1509 lib/silcutil/unix/silcunixnet.c. All routines that take
1510 address as argument now supports both IPv4 and IPv6 addresses.
1512 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1514 * Fixed LIST command reply sending in server. Affected file
1517 * Server now sends the kicker's client ID in the KICK notify
1518 to the kicked client. Affected file silcd/command.c.
1520 * The client library now parses the kickers client ID and
1521 UI displays it. Affected files lib/silcclient/client_notify.c
1522 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1524 * Made all payload parsing function prototypes consistent.
1525 They all take now const unsigned char * and uint32 pair as
1526 the payload data instead of SilcBuffer. Changes all around
1527 the source tree. Other unsigned char* -> const unsigned char*
1528 changes around the tree as well.
1530 * Optimized SFTP client and server packet sending not to
1531 allocate new buffer for each packet but to recycle the
1532 first allocated buffer. Affected files are
1533 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1535 * Optimized the SFTP client to use SilcList instead of
1536 SilcDList for requests, because it is faster. Affected file
1537 is lib/silcsftp/sftp_client.c.
1539 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1540 into lib/silccore/silcid.[ch].
1542 Renamed silcpayload.[ch] into silcargument.[ch].
1544 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1546 * If client entry is deleted with active key agreement
1547 session, abort the session.
1549 The silc_client_abort_key_agreement now calls the completion
1550 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1552 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1555 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Don't use __restrict in older GCC's. Affected file is
1558 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1560 * silc_net_localhost now attempts to reverse lookup the
1561 IP/hostname. Affected file lib/silcutil/silcnet.c.
1563 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1564 command. It can be used to gain founder privileges at
1565 the same time when joining the channel.
1567 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1568 kicker's client ID as well. Updated protocol specs.
1570 Defined that the server must send SILC_COMMAND_IDENTIFY
1571 command reply with error status to client who sent
1572 private message with invalid client ID.
1574 Updated the protocol specification.
1576 * Added silc_server_send_command_reply to send any
1577 command reply. Affected file silcd/packet_send.[ch].
1579 * Added silc_id_payload_encode_data to encode ID payload
1580 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1582 * The server now send IDENTIFY command reply with error
1583 status if client ID in private message is invalid. Affected
1584 file silcd/packet_receive.c.
1586 * Save the server key file with server's IP address in
1587 the filename instead of hostname. The affected file is
1588 irssi/src/silc/core/client_ops.c.
1590 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1595 * Added libtool support for compiling shared objects in
1596 lib/silcsim. Affected file configure.in.pre and
1597 lib/silcsim/Makefile.am. Original patch by cras.
1599 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Pid file configuration, and server's config file fixes
1602 patch by toma. Updated CREDITS file.
1604 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Fixed silc_client_channel_message to not try to decrypt
1607 the message twice if it resolved the destination client
1608 information. This could cause of dropping one channel
1609 message. Affected file lib/silcclient/client_channel.c.
1611 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1614 lib/silcclient/client.c. This function is used when the SILC
1615 Client is run under some other scheduler, or event loop or
1616 main loop. On GUI applications, for example this may be
1617 desired to used to run the client under the GUI application's
1618 main loop. Typically the GUI application would register an
1619 idle task that calls this function multiple times in a second
1620 to quickly process the SILC specific data.
1622 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1624 * Fixed silc_server_drop() for dropping the supplementary
1625 groups as well, this could cause a security hole on some
1628 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1633 * Write PID file after dropping privileges. Added -F option
1634 to run server on foreground. A patch by debolaz.
1635 Affected files silcd/server.c, silcd/silcd.c.
1637 * Fixed MOTD to return the MOTD file server name. Affected
1638 file silcd/command.c.
1640 * Added INFO command reply handling to the Irssi SILC Client.
1641 Affected file irssi/src/silc/core/client_ops.c.
1643 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1645 * Fixed the silc_idcache_list_* routines to really support
1646 the dynamic list. Fixes a crash. Affected file is
1647 lib/silccore/silcidcache.c.
1649 * Fixed the LIST command reply to really call LIST command's
1650 pending callbacks. Affected file silcd/command_reply.c.
1652 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Update conn->local_entry->nickname after giving NICK
1655 command. Affected file lib/silcclient/command.c.
1657 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1659 * Added the [pid] option to the silcd configuration file
1661 Affected files: serverconfig.[ch] and silcd.c
1663 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Save fingerprint in WHOIS command reply in server.
1666 Affected file silcd/command_reply.c.
1668 * Fixed NICK commands pending callback registration.
1669 Affected file lib/silcclient/command.c.
1671 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Use ++server->cmd_ident when sending commands in server,
1674 instead of random number. Affected file silcd/command.c.
1676 * Fixed GETKEY command reply to call actually GETKEY pending
1677 command callbacks. Affected file silcd/command_reply.c.
1679 * A bit stricter check for nicknames. Check for same nickname
1680 in NICK command also. Affected file silcd/command.c.
1682 * Do not call INFO command everytime client ID changes, only
1683 during first connecting. Affected file lib/silcclient/client.c.
1685 * Set the new nickname only after successful command reply for
1686 NICK command is returned by server. Affected file
1687 lib/silcclient/command.c.
1689 * Remove nicknames from nicklist during server_signoff notify.
1690 Should fix /NAMES bit more. The affected file is
1691 irssi/src/silc/core/silc-channels.c.
1693 * Added `fingerprint' field to the SilcIDListData in the
1694 silcd/idlist.h to hold the fingerprint of the client's
1697 Send the fingerprint of the client's public key in WHOIS
1700 Affected files silcd/command.c, and silcd/idlist.[ch].
1702 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1703 create fingerprint from given data.
1705 * Show the fingerprint of the client's public key in WHOIS.
1706 Affected files irssi/src/module-formats.[ch] and
1707 irssi/src/silc/core/client_ops.c.
1709 * Format the multiple same nicknames also during JOIN and
1710 NICK_CHANGE notifys. Affected file is
1711 lib/silcclient/client_notify.c.
1713 * Do not print error on screen for invalid private message
1714 payload since it can come if someone is sending private
1715 messages with wrong key. Affected file
1716 lib/silccore/silcprivate.c.
1718 * Fixed multiple concurrent /PING crash. Affected file
1719 lib/silcclient/command.c.
1721 * Changed the wrong ID encoding. All IP addresses must be
1722 in MSB first order in encoded format. They were encoded
1723 wrong and was in LSB format. Affected files are
1724 silcd/serverid.c, lib/silcutil/silcutil.c.
1726 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1728 * Call the `connect' client operation through the scheduler
1729 in case of error. Affected file lib/silcclient/client.c.
1731 * Call the `failure' client operation even if the error
1732 occurred locally during a protocol. Affected file is
1733 lib/silcclient/protocol.c.
1735 * Added support of sending LIST command to router from normal
1736 server. This way normal server can get list of all channels
1737 in the network too. Fixed the channel list sending in the
1738 server too. Affected files are silcd/command.c, and
1739 silcd/command_reply.[ch].
1741 * Added silc_server_update_channels_by_server and
1742 silc_server_remove_channels_by_server. They are used during
1743 disconnection of primary router and in backup router protocol.
1744 Affected file silcd/server_util.[ch], silcd/server.c and
1745 silcd/server_backup.c.
1747 * Fixed channel adding to global list in IDENTIFY command
1748 reply in server. Affected file silcd/command_reply.c.
1750 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * If the incoming packet type is REKEY or REKEY_DONE process
1753 that packet always synchronously. Fixes yet another MAC
1754 failed error on slow (dialup) connections. Affected file
1755 lib/silcclient/client.c and silcd/server.c.
1757 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1759 * Call check_version SKE callback for initiator too. Affected
1760 file lib/silcske/silcske.c.
1762 * Implemented fix for security hole found in the SKE that was
1763 fixed in the specification few days back; the initiator's
1764 public key is now added to the HASH value computation.
1765 Added backwards support for the old way of doing it too, for
1766 old clients and old servers. Affected file is
1767 lib/silcske/silcske.c.
1769 * Enabled mutual authentication by default in SKE. If initiator
1770 is not providing mutual authentication the responder will
1771 force it. This will provide the proof of posession of the
1772 private key for responder. The affected files are
1773 lib/silcclient/protocol.c and silcd/protocol.c.
1775 * Do not cache anymore the server's public key during SKE.
1776 We do mutual authentication so the proof of posession of
1777 private key is done, and if the server is authenticated in
1778 conn auth protocol with public key we must have the public
1779 key already. Affected file silcd/protocol.c.
1781 * Added new global debug variable: silc_debug_hexdump. If
1782 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1783 file lib/silcutil/silclog.[ch].
1785 * Fixed compilation warning due to char * -> const char *.
1786 Affected files lib/silcutil/silcnet.h, and
1787 lib/silccore/silcauth.[ch].
1789 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1791 * Fixed CMODE command when new channel key was created. If
1792 the creation failed the old key was removed. Next time giving
1793 same command would crash the server since the old key was
1794 freed already. Affected file silcd/command.c.
1796 * Fixed the silc_server_announce_get_channels to not crash
1797 on reconnect. Affected file silcd/server.c.
1799 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * Added silc_log_set_debug_string function to set a regex
1802 string to match for debug output. Only the function names,
1803 or filenames matching the given debug string is actually
1804 printed. This way it is possible to filter out those debug
1805 strings that user is not interested in.
1807 Fixed a bug in silc_string_regexify.
1809 Affected files lib/silcutil/silclog.[ch], and
1810 lib/silcutil/unix/silcunixutil.c.
1812 * Changed the -d options in both server and Irssi SILC client
1813 to take the debug string as argument. Affected files
1814 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1816 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Added silc_hash_babbleprint to create a Bubble Babble
1819 Encoded fingerprint. The encoding is developed by Antti
1820 Huima (draft-huima-babble-01.txt), and it creates human
1821 readable strings out of binary data. Affected file
1822 lib/silccrypt/silchash.[ch].
1824 * Print the babble print now in addition of fingerprint as well
1825 in Irssi SILC client. Affected files are
1826 irssi/src/fe-common/silc/module-formats.[ch],
1827 irssi/src/fe-common/silc/core/client_ops.c.
1829 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Fixed a security problem found in SKE. The initiator's
1832 public key too is now added to the HASH hash value creation
1833 which is signed by the responder to create the SIGN value.
1834 This will prevent anyone in the middle to lie to the responder
1835 about the initiator's public key. If this is done now, the
1836 man in the middle will get caught. Updated the protocol
1839 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Better installation directory handling. Configure module
1842 paths and other paths automatically to example_silc* files
1843 in doc/. A patch by toma.
1845 * Fixed compiler warning from MPI library, and from SILC RNG.
1848 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1849 It can be configured with ./configure. A patch by toma.
1851 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Find correct make to use in prepare-clean. A patch by
1854 toma. Affected file prepare-clean.
1856 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1858 * Added irssi variables use_auto_addr, auto_bind_ip,
1859 auto_bind_port and auto_public_ip.
1861 * Changed the interface for silc_client_send_key_agreement
1862 in lib/silcclient/silcapi.h
1866 irssi/src/silc/core/silc-core.c
1868 lib/silcclient/silcapi.h
1869 irssi/src/silc/core/silc-channels.c
1870 lib/silcclient/client_keyagr.c
1873 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Added silc_pkcs_public_key_compare to compare two
1876 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1878 * Check that the client who set the founder mode on the
1879 channel is the same client that is giving the founder
1880 mode to itself. It is done by comparing the saved public
1881 key (it is saved even in the authentication is passphrase).
1882 Affected file silcd/command.c.
1884 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Do not process packet for disconnected socket connection.
1887 Affected file lib/silccore/silcpacket.c.
1889 * Process the DISCONNECT packet through scheduler in the
1890 client library. Affected file lib/silcclient/client.c.
1892 * Fixed the silc_client_packet_parse to not to increase
1893 the packet sequence number if the conn->sock and the
1894 current socket connection is not same. This can happen
1895 for example during key agreement when the conn includes
1896 multiple socket connections (listeners). Affected file
1897 lib/silcclient/client.c.
1899 * The sender of the file transfer request now provides also
1900 the pointer (listener) for the key exchange protocol. If
1901 the listener cannot be created then it sends empty key
1902 agreement and lets the receiver provide the listener.
1904 Added `local_ip' and `local_port' arguments to the
1905 silc_client_file_send. If they are provided they are used,
1906 if not then it will attempt to find local IP address, if
1907 not found or bind fails then the remote client will provide
1910 Affected files are lib/silcclient/client_ftp.c and
1911 lib/silcclient/silcapi.h.
1913 * Extended the FILE SEND command to support defining the
1914 local IP and port for key exchange listener. They are
1915 optional. Affected file irssi/src/silc/core/silc-servers.c.
1917 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Defined to WHOIS command reply the sending of fingerprint
1920 of the client's public key (if the proof of posession of the
1921 corresponding private key is verified by the server).
1922 Updated to the protocol specification.
1924 * Added support of receiving the client's public key's
1925 fingerprint in command reply in client library. Affected
1926 file is lib/silcclient/command_reply.c, and
1927 lib/silcclient/idlist.[ch].
1929 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Do not send over 128 chars long nickname to the server
1932 in NICK command. Affected file lib/silcclient/command.c.
1934 * Do not send over 256 chars long channel names to the server
1935 in JOIN command. Affected file lib/silcclient/command.c.
1937 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Assure that silc_server_close_connection cannot be called
1940 twice for same socket context. Affected file is
1943 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Send error message to application if opening file for
1946 writing during file transfer fails. Affected file is
1947 lib/silcclient/client_ftp.c.
1949 Remove all file transfer sessions for a client that we're
1950 removing from ID cache.
1952 Affected file is lib/silcclient/client_ftp.c.
1954 * Fixed silc_net_addr2bin to return correct address. Affected
1955 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1957 * Fixed file transfer session removing on signoff notify.
1958 Affected file irssi/src/silc/core/silc-servers.c.
1960 * Added the SilcClientFileError to be returned in the monitor
1961 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1962 Affected file lib/silcclient/silcapi.h.
1964 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Fixed a crash in silc_client_ftp_free_sessions and
1967 silc_client_ftp_session_free_client. Affected file
1968 lib/silcclient/client_ftp.c.
1970 * Added `disabled' field in the SilcChannelEntry in the server
1971 to indicate if the server entry is disabled. Affected file
1972 silcd/idlist.h, silcd/command[_reply].c.
1974 * SILC server adds now /var/run/silcd.pid everytime it is
1975 started. Affected file silcd/silcd.c.
1977 * Added silc_server_packet_send_clients to send a packet to
1978 the provided table of client entries. Affected file
1979 silcd/packet_send.[ch].
1981 * Fixed a crash in client resolving in client_prvmsg.c in
1982 client library. Affected file lib/silcclient/client_prvmsg.c.
1984 * Do not actually remove the client directly from ID cache
1985 during SERVER_SIGNOFF, but invalidate it. This way we
1986 preserve the WHOWAS info for the client. Affected file
1987 silcd/server_util.c.
1989 * Fixed SERVER_SIGNOFF notify handling in the server. The
1990 server is now able to process incoming SERVER_SIGNOFF notify
1991 for a server that it doesn't even know about. It will remove
1992 the clients provided in the notify. Affected file
1993 silcd/packet_receive.c.
1995 * Check for partial packet in data queue after every packet that
1996 was found from the queue. Return and wait for more data if
1997 there is partial data in queue. Affected file is
1998 lib/silccore/silcpacket.c.
2000 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2004 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2005 Affected files lib/silcclient/silcapi.h and
2006 lib/silcclient/client_ftp.c.
2008 * Check that newsize in silc_buffer_realloc is larger than
2009 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2011 * Added better monitor of file transfers. It now monitors
2012 key agreement protocol during the file transfer too. Added
2013 error reporting too. Affected files
2014 irssi/src/silc/core/silc-servers.c,
2015 irssi/src/fe-common/silc/module-formats.[ch].
2017 * Wrote a help file for FILE command.
2019 * Added silc_rng_global_get_byte_fast to get not-so-secure
2020 random data as fast as possible. Random data is read from
2021 /dev/urandom if available and from the SILC RNG if not
2022 available. It is used in padding generation. Affected file
2023 lib/silccrypt/silcrng.[ch].
2025 * All packets in client library are now processed synchronously.
2026 Optimized packet processing a lot. Affected file
2027 lib/silcclient/client.c.
2029 * All server connection packets are processing synchronously
2030 now in server, to optimize packet processing. Affected file
2033 * Include files are installed now only in Toolkit distribution
2034 if make install is given. Affected files: all Makefile.am's.
2036 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Assure that silc_client_notify_by_server_resolve does not
2039 resolve the client information multiple times. If it cannot
2040 be found by the first it cannot be found at all. Affected
2041 file lib/silcclient/client_notify.c.
2043 * Fixed WHOWAS command reply calling. Affected file
2044 lib/silcclient/command_reply.c.
2046 * Removed all references to silc_idlist_get_client from the
2047 Irssi SILC client since that call is internal call used by
2048 the library. The Irssi SILC client will use now client
2049 retrieval functions found in silcapi.h.
2051 * Fixed a bug in resolving nickname info before sending
2052 private message. It used freed memory. Affected file
2053 irssi/src/silc/core/silc-servers.c.
2055 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Assure my_channels statistics cannot go negative in server.
2058 Affected files silcd/server.c, silcd/server_util.c.
2060 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2072 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2074 * Added silc_net_localip to return local host's IP address.
2075 Affected file lib/silcutil/silcnet.[ch].
2077 * If key exchange or rekey protocol is active for a connection
2078 parse all packets syncronously since there might be packets
2079 in packet queue that we are not able to process without first
2080 processing packets before them. Affected file silcd/server,
2081 lib/silcclient/client.c.
2083 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2084 whether library should continue processing the packet.
2085 Affected file lib/silccore/silcpacket.h.
2087 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2113 * Renamed silc_file_read and silc_file_write to functions
2114 silc_file_readfile and silc_file_writefile. Added function
2115 silc_file_open and silc_file_close. Affected files
2116 lib/silcutil/silcutil.[ch].
2118 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Resolve the client info when received private message or
2121 channel message for a client which nickname we don't know.
2122 Affected files lib/silcclient/client_prvmsg.c and
2123 lib/silcclient/client_channel.c.

2131 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2132 is incomplete and is being resolved, it won't be resolved
2135 Make sure also that USERS command reply does not resolve
2136 twice information. Affected file is
2137 lib/silcclient/command_reply.c.
2139 Make sure that silc_client_get_clients_by_list does not
2140 resolve twice same information.
2142 * Check for valid client->id in the silc_server_free_client_data.
2143 Affected file silcd/server.c.
2145 * Fixed /GETKEY nick@server not to crash if the server entry
2146 is not found. Affected file lib/silcclient/command.c.
2148 * Fixed the silc_server_check_cmode_rights to check the
2149 requested modes correctly. Affected file silcd/command.c.
2151 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Better checks for non-printable chars in nick added.
2154 Affected file silcd/command.c.
2156 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Call the silc_server_udpate_servers_by_server in the
2159 primary router that comes back online in the backup resuming
2160 protocol. Otherwise it routes packets wrong. Affected file
2161 silcd/server_util.[ch], silcd/server_backup.c.
2163 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2165 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2166 lib/silcutil/silcbuffmt.[ch].
2168 * Redefined the SILC packet header to include the padding
2169 length. Affected file lib/silccore/silcpacket.[ch].
2171 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2172 length for maximum padding up to 128 bytes). Affected
2173 file lib/silccore/silcpacket.h.
2175 * Removed all backwards support for old 0.5.x MAC thingies.
2176 The SILC packet header change makes it impossible to be
2177 backwards compatible.
2179 * Send the ENDING packet with timeout in the backup resuming
2180 protocol. This is to assure that all routers has connected
2181 to the primary router. Affected file silcd/server_backup.c.
2183 * Changed the RNG to take the first IV from random data. It
2184 used to take it from zero actually. Changed the RNG also
2185 to use /dev/urandom during session. /dev/random is used
2186 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2188 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Changed the SILC packet header to have the first two bytes
2191 (the packet length) encrypted. Affected files aroung the
2192 code tree, lib/silccore/silcpacket.[ch]. Removed the
2193 SilcPacketCheckDecrypt callback. It is not needed anymore
2194 since the silc_packet_receive_process will determine now
2195 whether the packet is normal or special.
2197 * Implemented the unidirectional MAC keys. Affected files
2198 lib/silcske/silcske.c, silcd/protocol.c and
2199 lib/silcclient/protocol.c.
2201 * Implemented the packet sequence number to the MAC computation.
2202 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2203 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2204 lib/silcclient/protocol.c.
2206 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Allow backup router to announce servers. All servers
2209 announced by backup router are added to the global list
2210 automatically. Update hte server's socket to our primary
2211 router also when backup router announces a server.
2212 Affected file silcd/packet_receive.c.
2214 * Do not update the client->router in the function
2215 silc_server_udpate_clients_by_server if the client is on
2216 global list. We might fail to find any specific server
2217 for locally connected clients and local cell clients. They
2218 should still use the `from' and not `to' as client->router.
2219 This fixes backup router resuming protocol. Affected file
2220 silcd/server_util.c.
2222 * Decrease channel statistics count only if the channel
2223 deletion worked. Affected files are silcd/server.c and
2224 silcd/server_util.c.
2226 * Added silc_server_update_servers_by_server to update origin
2227 of all server entries. Used during backup router protocol.
2228 Affected files silcd/server_util.[ch], silcd/server.c. and
2229 silcd/backup_router.c.
2231 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2232 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2233 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2234 lib/silccrypt/silchmac.c.
2236 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Assure that router cannot reroute the same channel message
2239 to the sender. Affected file silcd/packet_receive.c.
2241 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Made better checks that the channel message is not sent
2244 to the router it came from. Affected file is
2245 silcd/packet_send.c. Fixed memory leak too.
2247 * Announce informations for incoming router connection, but
2248 only after checking if it is replaced by backup router.
2249 Affected file silcd/packet_receive.c.
2251 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Fixed the backup resuming protocol to work in multiple
2254 router environment. Affected file silcd/server_backup.c.
2256 * Route packet only to one router in the function
2257 silc_server_packet_send_to_channel. Affected file is
2258 silcd/packet_send.c.
2260 * Fixed silc_server_send_notify_dest to set the broadcast
2261 flag. Fixed the silc_server_send_notify_topic to actually
2262 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2263 Affected file silcd/packet_send.c.
2265 * Changed the SFTP Filesystem interface. Changed the
2266 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2267 the filesystem operation function. The SilcSFTPFilesystem
2268 is now a context that is allocated by all filesystem allocation
2269 functions and it already includes the operations structure
2270 and filesystem specific context. It is given as argument
2271 now to the silc_sftp_server_start. This made the interface
2272 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2273 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2275 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Changed the backup router adding and getting interfaces
2278 in the server. The router that will be replaced by the
2279 specified backup router is now sent as argument. Affected
2280 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2283 * Added silc_net_addr2bin_ne to return the binary form of
2284 the IP address in network byte order. Affected files
2285 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2287 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Check for existing server ID in silc_server_new_server
2290 and in silc_server_connect_to_router_final and remove the
2291 old entry if it exists. Affected file silcd/packet_receive.c,
2294 * Send the channel message always to only one router, either
2295 in upstream or downstream. Affected file is
2296 silcd/packet_send.c.
2298 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Wrote the definition of the backup resuming protocol to the
2301 protocol specification.
2303 * Removed one redundant channel key generation from normal
2304 server during joining procedure. Removed one redundant
2305 channel key sending from server to router during joining
2306 procedure. Affected file silcd/command.c.
2308 * Made minor bugfixes to the backup router resuming protocol.
2309 Affected file silcd/server_backup.c, server.c.
2311 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Added --disable-asm configuration option. Affected files
2314 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2317 * Implemented the backup resuming protocol that is used to
2318 resume the primary router position in the cell after the
2319 primary router comes back online. Affected files
2320 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2321 and silcd/server_util.[ch].
2323 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Sleep two (2) seconds after sending QUIT command to server.
2326 Affected file lib/silcclient/command.c.
2328 * Assure that if outgoing data buffer is pending do not force
2329 send any data. Affected file silcd/packet_send.c.
2331 * Assure that if outgoing data buffer is pending do not force
2332 send any data. Affected file lib/silcclient/client.c.
2334 * Implemented the backup router support when the primary router
2335 goes down. The servers and routers can now use the backup
2336 router as new primary router without loosing connectivity.
2338 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2341 in the server to indicate disabled entry. All data read
2342 from the connection will be ignored and no data is sent
2343 for entry that is disabled. Affected files are
2344 silcd/idlist.h, silcd/server.c.
2346 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Created SFTP client and server test programs in the
2349 lib/silcsftp/tests directory.
2351 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Implemented memory filesystem (virtual filesystem) for
2354 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2357 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Implemented the SFTP (SSH File Transfer Protocol) to the
2360 lib/silcsftp. It includes SFTP client and SFTP server
2363 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Moved lib/silccore/silcprotocol.[ch] to the
2366 lib/silcutil library.
2368 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2369 take variable argument list pointer as argument. Affected
2370 file lib/silcutil/silcbuffmt.[ch].
2372 * Added silc_buffer_set function that is used to set data
2373 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2374 Affected file lib/silcutil/silcbuffer.h.
2376 * Changed various routines in the core library to use the new
2377 silc_buffer_set instead of allocating new buffer only for
2380 * Added 64-bit value formatting and unformatting support to the
2381 silc_buffer_[un]format routines. Affected file is
2382 lib/silcutil/silcbuffmt.[ch].
2384 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2385 to includes/bitmove.h.
2387 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Fixed channel user mode saving in client library. Affected
2390 file lib/silcclient/command[_reply].c.
2392 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Defined the file transfer to the SILC Protocol. Added
2395 new packet type SILC_PACKET_FTP and defined File Transfer
2396 Payload. The mandatory file transfer protocol is SFTP
2397 (SSH File Transfer Protocol). Affected file in addition
2398 of the internet draft is lib/silccore/silcpacket.h.
2400 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2401 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2402 is used as part of backup router protocol when the primary
2403 router of the cell is back online and wishes to resume
2404 the position as primary router.
2406 * Redefined the MAC generation keys in the protocol. The
2407 same key is not used anymore in both direction. Both
2408 direction will now use different keys for sending and
2409 receiving. This fixes a potential security flaw. This
2410 change causes incompatibilities in the protocol.
2412 * Redefined also the MAC computation from the packet.
2413 An packet sequence number is now added to the MAC
2414 computation. This prevents possible replay attacks against
2415 the protocol. This change too causes incompatibilities
2418 Added `sequence' field to the SilcPacketContext to hold
2419 the current sequence number for the packet.
2421 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Added `created' field to the SilcIDListData in the file
2424 silcd/idlist.h to indicate the time when the entry was
2427 * Added `created' field to the SilcChannelEntry too. Affected
2428 file silcd/idlist.h.
2430 * Added `creation_time' aguments to all the announcement functions
2431 in the server. If it is provided then only the entries that
2432 was created after the provided time frame are actually
2433 announced. Affected file silcd/server.[ch].
2435 * The protocol says that the Channel ID's IP address must be
2436 based on the router's IP address. Added check for this in
2437 the silc_server_new_channel when processing incoming New Channel
2438 Payload. Affected file silcd/packet_receive.c.
2440 * Print out the correct version with --version in SILC client.
2441 Affected file irssi/src/silc/core/silc-core.c.
2443 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Fixed WHOWAS command to check for completnes of the client
2446 entry always, not just when the command is coming from client.
2447 Affected file silcd/command.c.
2449 * Added new function silc_server_packet_queue_purge to purge the
2450 outgoing data queue to the network. After the function returns
2451 it is guaranteed that the outgoing packet queue is empty.
2452 Affected file silcd/packet_send.[ch].
2454 * Purge the outgoing packet queue in the rekey protocol's final
2455 callback to assure that all rekey packets go to the network
2456 before quitting the protocol. Affected file silcd/server.c.
2458 * Added silc_client_packet_queue_parse as similar function as
2459 in server to the client library. The affected file is
2460 lib/silcclient/client.c.
2462 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Splitted silcd/server.c and created silcd/server_util.[ch]
2465 for utility functions.
2467 * Added new socket flag SILC_SF_DISABLED to indicate that the
2468 connection is open but nothing can be sent to or received from
2469 the connection. Affected file lib/silcutil/silsockconn.[ch].
2470 The checking for disabled socket is checked in the low level
2471 silc_socket_write and silc_socket_read functions.
2473 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Allow only nicknames and channel names that fits into the
2476 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2478 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * When processing JOIN command reply in server check that if
2481 the channel exists in our global list we'll move it the local
2482 list. Affected file silcd/command_reply.c.
2484 * Fixed the check whether client is joined on the channel already
2485 in JOIN command. Affected file lib/silcclient/command.c.
2487 * Fixed the JOIN command reply to check whether the channel
2488 already exists. Affected file lib/silcclient/command_reply.c.
2490 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Added silc_ske_status_string to map the SKE error numbers
2493 to readable strings. The affected files are
2494 lib/silcske/silcske[_status].[ch].
2496 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * Do not show the private channels on the WHOIS channel list
2499 as it is not allowed by the protocol. The affected file is
2502 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Assure that the packet length digged from the actual packet
2505 is something sensible in the silc_packet_decrypt_rest_special
2506 in lib/silccrypt/silcpacket.c.
2508 * Free and NULL the allocated pointer in silc_hmac_alloc if
2509 the HMAC allocation fails. The affected file is
2510 lib/silccrypt/silchmac.c.
2512 * Print the selected security properties to the log files in
2513 the server. Affected file silcd/protocol.c.
2515 * Add SKE's reference counter even if calling the completion
2516 callback manually. Otherwise it goes negative, although it
2517 does not cause any problems. The affected file is
2518 lib/silcske/silcske.c.
2520 * Remove the client entry with short timeout after giving the
2521 KILL command. Affected file lib/silcclient/command.c.
2523 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2524 case all found clients are already disconnected (WHOWAS would
2525 found them) in the server. Affected file silcd/command.c.
2527 * Update the last_receive (time of last data received) to be
2528 updated only when received private or channel message so that
2529 the idle time showed in WHOIS makes more sense.
2531 * Added boolean field `valid' in to the SilcClientEntry in the
2532 client library to indicate whether the entry is valid or not.
2533 This fixes the nickname change bug on channel when changing
2534 the nickname to be same than the old (like nick to Nick) the
2535 nickname formatter doesn't set the new nick anymore to Nick@host.
2536 Affected file lib/silcclient/idlist.[ch].
2538 * Now actually fixed the nickname changing on disconnection.
2539 Added new function silc_change_nick to the Irssi SILC Client.
2540 Affected file irssi/src/silc/core/client_ops.c,
2541 irssi/src/silc/core/silc-nicklist.[ch].
2543 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Check that the public key exists in the GETKEY command before
2546 trying to encode it. Affected file silcd/command.c.
2548 * Print some notifications on received public keys with GETKEY
2549 command in the Irssi SILC Client. Affected files are
2550 irssi/src/fe-common/silc/module-formats.[ch],
2551 irssi/src/silc/core/client_ops.c.
2553 * Use IDENTIFY command to resolve the server information in the
2554 GETKEY command instead of INFO command. Affected file
2555 lib/silcclient/command.c.
2557 * All command reply functions in the client library now calls
2558 the pending command reply callbacks even if an error has
2559 occurred. The server has done this a long time and now it was
2560 time to move the client library to this as well. Now all
2561 errors can be delivered back to the pending command reply
2562 callbacks if necessary. Affected files are
2563 lib/silcclient/command[_reply].[ch].
2565 * Change the nickname on disconnection back to the username
2566 because in reconnect the server will enforce it to it anyway.
2567 Affected file irssi/src/silc/core/silc-servers.c.
2569 * Fixed a config file parsing bug in the Irssi SILC client.
2570 Affected file irssi/src/silc/core/clientconfig.c.
2572 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * When printing the channel mode on JOIN, verify that the
2575 channel key and channel's HMAC are valid. Affected file
2576 irssi/src/silc/core/client_ops.c.
2578 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2581 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2582 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2584 * Removed channel key rekey task deleting from the function
2585 silc_server_save_channel_key. Affected file silcd/server.c.
2586 Added explicit timeout task context instead that is used to
2587 delete the task if we are registering a new task before the
2588 new task has elapsed.
2590 * When channel key rekey occurs the client library now saves
2591 the old channel key for a short period of time (10 seconds) and
2592 is able to use it in case some is still sending channel
2593 messages encrypted with the old key after the rekey. Affected
2594 file lib/silcclient/[idlist.h|client_channel.c].
2596 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Added check to the silc_server_new_id_real to not accept
2599 new ID if it is the sender's own ID. Affected file is
2600 silcd/packet_receive.c.
2602 * Assure that we do not announce ourself or the one we've
2603 sending our announcements when we're router and are announcing
2604 servers to our primary router. Affected file silcd/server.c.
2606 * Fixed silc_server_command_identify_check_client to assemble
2607 correct WHOIS packet. It send corrupted WHOIS packet and
2608 caused problem with router to router connections. Affected
2609 file silcd/command.c.
2611 Fixed also silc_server_command_whois_check the same way
2612 as for the IDENTIFY command.
2614 * Added new SilcIDListStatus to the server in the SilcIDListData
2615 structure. The status now includes the current status of
2616 the entry (like registered, resolved etc.). Affected file
2617 silcd/idlist.[ch]. Defined a bunch of different status types
2618 as well. This replaced the old boolean registered field as well.
2620 Added resolve_cmd_ident field to the SilcClientEntry structure
2621 too so that if the entry is for example being resolved so
2622 another command may attach to the same pending command reply
2623 without requiring to resolve the same entry again. This concept
2624 should optimize the WHOIS and the IDENTIFY resolving under
2625 heavy load by taking away unnecessary resolving for entries
2626 that are being resolved already.
2628 Added support for adding multiple pending commands for one
2629 command idenfier. Affected file silcd/command[_reply].[ch].
2631 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2632 before deleting the data. Otherwise the hash table will have
2633 freed data in comparison functions. Affected file is
2634 silcd/command_reply.c.
2636 * Fixed silc_idlist_replace_client_id to add the new entry to
2637 the cache with NULL nickname. Otherwise there will be invalid
2638 memory as the nickname after the nickname is freed. Affected
2639 file silcd/packet_receive.c.
2641 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2642 saved into wrong slots because the previous number of entries
2643 was not taken into account. Affected file silcd/idlist.c.
2644 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2646 * If we are router and we receive JOIN notify to a channel that
2647 does not have any users then notified client is marked as the
2648 channel founder, as it is it. The affected file is
2649 silcd/packet_receive.c
2651 * Added to the extended hash table API's table_del_*ext functions
2652 the destructor as argument too, so that the caller can decide
2653 which destructor to use or whether to use destructor at all.
2654 Affected file lib/silcutil/silchashtable.[ch].
2656 * Fixed ID Cache purging. It actually deleted the entries from
2657 the hash table after the data was freed. The hash table ended
2658 up comparing freed memory. The affected file is
2659 lib/silccore/silcidcache.c.
2661 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Fixed Irssi SILC client's KILL command's HELP syntax.
2665 * The USERS command now resolves the detailed user information
2666 if the userinfo field is missing. Affected file is
2667 lib/silcclient/command_reply.c.
2669 * Do not print error in silc_file_read if the read file does
2670 not exist. Just silently return NULL. Affected file is
2671 lib/silcutil/silcutil.c.
2673 * Fixed the silc_log_output to not wine about NULL filename
2674 and to not create some bogus " " filename. Affected file is
2675 lib/silcutil/silclog.c.
2677 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Fixed various printing bugs on the user interface in the
2680 Irssi SILC Client. Minor changes that were forgotten from
2683 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Fixed the configure.in.pre and the compilation and distribution
2686 environment to support the new autoconf 2.52. That version is
2687 now required to compile the CVS trunk.
2689 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2692 to generally parse user@fqdn format strings. Affected file
2693 lib/silcutil/silcutil.c.
2695 * Added nickname_format and nickname_force_format fields to the
2696 SilcClientParams structure. The first one defines the format
2697 for the nicknames that the library will enforce if the receives
2698 multiple same nicknames. The second one is boolean value and
2699 can be used to force the library to always enforce the format
2700 to the nicknames regardles whether there are multiple nicknames
2701 or not. This configurable formatting was employed to flexibly
2702 support accessing multiple nicknames from the user interface.
2703 The userinterface can now set the nicknames to what ever format
2704 they prefer. Affected file lib/silcclient/silcapi.h.
2706 Added function silc_client_nickname_format to the file
2707 lib/silcclient/idlist.c. It performs the nickname formatting.
2709 Added new field `hostname´ to the SilcClientEntry context.
2710 It holds the hostname of the client. Affected file is
2711 lib/silcclient/idlist.h.
2713 * Irssi SILC Client sets the nicknames in nick@hostn format.
2714 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2715 irssi/src/silc/core/silc-core.c.
2717 The WHOIS printing now also shows both the real nickname and
2718 the formatted nickname so that user knows how to access the
2719 user if there are multiple same nicknames cached. Affected
2720 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2721 printing formatting too to take the hostname now as a separate
2722 argument. The Affected file is
2723 irssi/src/fe-common/silc/modules-formats.[ch].
2725 * Changed the silc_client_get_clients_local to accept the formatted
2726 nickname as argument. It accepts the real nickname too but the
2727 formatted nickname can be used to find the true entry from
2728 multiple entries. Affected file lib/silcclient/silcapi.h and
2729 lib/silcclient/idlist.c.
2731 * Added nickname_format_parse field to the SilcClientParams.
2732 It is a callback function provided by the application to parse
2733 the nickname out of the formatted nickname string. The library
2734 calls it to get the nickname from the formatted string. Since
2735 the application generally knows better the format of the nickname
2736 string it parses it instead of the library, even though library
2737 encodes the formatted string. If the callback function is not
2738 provided then the library will use the string as is. The
2739 affected file is lib/silcclient/silcapi.h.
2741 * All the nickname strings passed to the client library in
2742 commands are now expected to be formatted nickname strings.
2743 If the command does not support the formatted nickname string
2744 it will assume that the sent string is the actual nickname.
2745 Affected file lib/silcclient/command.c.
2747 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2749 * Added public key authentication support to OPER and SILCOPER
2750 commands in the client library. Affected file is
2751 lib/silcclient/command.c.
2753 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Changed the get_auth_methdod client operation to be asynchronous.
2756 It can be async if the application resolves the authentication
2757 method from the server during the negotiation. Added new
2758 SilcGetAuthMeth completion callback that the application will
2759 call after resolving the authentication method.
2761 Added function silc_client_request_authentication_method that
2762 the application can use to resolve the authentication method
2763 from the server. Added also SilcConnectionAuthRequest callback
2764 that the library will call after the server has replied. The
2765 application can call this function if it does not know the
2766 current authentication method.
2768 Affected files are lib/silcclient/client.c and
2769 lib/silcclient/silcapi.h.
2771 * The Irssi SILC client now automatically resolves the authentication
2772 method incase any configuration information is not present (and
2773 currently there never is). The affected file is
2774 irssi/src/silc/core/client_ops.c.
2776 * Fixed public key authentication from the client library.
2777 Affected file lib/silcclient/protocol.c. Changed also the
2778 protocol specification about the public key authentication in
2779 the connection authentication protocol. The actual data to be
2780 signed is now computed with a hash function before signing.
2782 * Fixed the public key authentication from the server as well.
2783 Affected file silcd/protocol.c.
2785 * Removed the mlock()'s from the memory allocation routines.
2786 Affected file lib/silcutil/silcmemory.c. The ./configure does
2787 not check anymore for the mlock(). Affected file is
2790 * Fixed USERS command in server to allow the execution of the
2791 command for private and secret channels if the client sending
2792 the command is on the channel. Affected file silcd/command.c.
2794 * Fixed silc_client_get_clients_local to return the clients
2795 count correctly. It could return wrong value. Affected file
2796 lib/silcclient/idlist.c.
2798 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2801 types. The assembler optimizations seemed not to like 64-bit
2802 data types. The assmebler optimizations thus are now enabled
2803 also for BSD systems as opposed to only enable them for Linux.
2805 * Do not check for threads at all on BSD systems. Affected
2806 file configure.in.pre.
2808 * Removed -n and -h options from the Irssi SILC Client since
2809 they are not used in silc.
2811 * Fixed the prime generation to assure that the first digit
2812 of the generated random number is not zero since our conversion
2813 routines does not like number strings that starts with zero
2814 digit. If zero digit is seen the random number is regenerated.
2815 This caused some corrupted RSA keys when the zero first digit
2816 was met. Affected file lib/silcmath/silcprimegen.c.
2818 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed WIN32 configuration in the ./configure script.
2821 Fixed to include xti.h on environments that has it.
2822 Patches by Carsten Ilchmann and andrew.
2824 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Changed the silc_id_create_client_id to be collision
2827 resistant. It is now assured that there cannot be created
2828 two same client ID's. I suspect that some weird bugs in
2829 the server were actually caused by duplicate Client IDs.
2830 Affected file silcd/serverid.[ch]. A router receiving
2831 new ID now also assures and informs the sending server
2832 if the ID caused collision.
2834 * Changed the silc_id_create_channel_id to also assure that
2835 there are no collisions.
2837 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Statement about ignoring the Mutual Authentication flag when
2840 performing rekey with PFS was a bit misleading. It is ignored
2841 if it was set in the initial negotiation, it cannot be even
2842 set in the rekey. Fixed in the ke-auth draft. Started the
2843 new versions of the protocol drafts in the doc/.
2845 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Fixed a bug in silc_client_command_identify_save when saving
2848 new channel information. The channel name was no duplicated
2849 and caused crash on exit. Affected file is
2850 lib/silcclient/command_reply.c.
2852 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Fixed the getkey command handling in the server. Send just
2855 empty OK reply to the sender if the key could not be fetched
2856 (but everything else was ok, like the key just was not available).
2857 Changed the public key parameter to optional in the protocol
2858 specs so that empty OK reply can be sent. Affected file
2861 Added a message to Irssi SILC client to tell to user if the
2862 server did not return a public key.
2864 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Fixed a channel key regeneration bug. It registered new
2867 timeout tasks exponentially until all system resources were
2868 used. Affected file silcd/server.c.
2870 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Added the SILC Document generator to the scripts/silcdoc.
2873 It can be used to generate the Toolkit Reference Manual out
2874 of the source tree. Internally it will also use the RoboDoc
2875 generator now imported in util/robodoc.
2877 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Added couple of return's in rekey protocol if error orccurred
2880 during the protocol. The execution must be terminated.
2881 Affected file silcd/protocol.c. Also, terminate the protocol
2882 always with timeout.
2884 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * The client's Client ID was created initally from the wrong
2887 nickname (it could have been in format nick@host) in the
2888 silc_server_new_client. Affected file silcd/packet_receive.c
2890 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Added some SILC_LOG_ERROR's to various error conditions
2893 if client could not be added to ID cache. Affected files
2894 silcd/packet_receive.c and silcd/server.c.
2896 * When client's sock->user_data is freed, NULL also the
2897 client->router and client->connection pointers. Added check
2898 for these pointers being NULL to various places around the
2899 code. Affected file silcd/server.c.
2901 * Added client->data.registered == TRUE checks to various
2902 places around the code to assure that unregistered client's
2903 are not handled when it is not allowed. Affected file
2906 * Added `bool registered' fields to all
2907 silc_idlist_[server|client]_get_* routines to indicate whether
2908 the fetched client needs to be registered or not. Affected
2909 file silcd/idlist.[ch].
2911 * Add your own entry as registered to the ID cache in the
2912 server. Affected file server.c.
2914 * Fixed a bug in silc_server_new_server. The SilcServer was
2915 set as the new server's context instead of SilcServerEntry.
2916 This naturally caused some weird bugs.
2918 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Do not delete the channel rekey task when adding it
2921 for in silc_server_create_channel_key.
2923 * Changed the silc_server_create_channel_key to return
2924 TRUE or FALSE to indicate the success of the channel key
2927 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Fixed MSVC++ project files and added missing files to
2930 Makefiles under win32/.
2932 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Do not add TCP_NODELAY flag if the operating system
2935 does not have it defined. Affected files are
2936 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2938 * Fixed buffer overflow from Irssi SILC Client. Affected
2939 file irssi/src/fe-common/core/themes.c.
2941 * Fixed double free in client library in the file
2942 lib/silcclient/client.c when disconnecting from server.
2944 * Applied double free patch from cras to Irssi SILC client.
2945 Affected files irssi/src/core/[modules/expandos].c
2947 * Fixed the disconnection handling to Irssi SILC Client.
2948 The application must call silc_client_close_connection
2949 in ops->connect client operation in case of failure of
2950 the connection. Affected file is
2951 irssi/src/silc/core/client_ops.c.
2953 * Do not set sock->protocol to NULL in the function
2954 silc_client_close_connection after executing the protocol's
2955 final callback since the sock might not be valid anymore.
2956 Affected file lib/silcclient/client.c.
2958 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Do not enable SILC_THREADS if the linking with libpthread
2961 did not happen. Affected file configure.in.pre.
2963 * Added notion to protocol specification that server must
2964 verify the sent authentication payload with CMODE when
2965 setting the channel founder key. Implemented it to the
2966 server. Affected file silcd/command.c.
2968 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Added _EXTRA_DIST SILC distribution variable to the
2971 distributions file. It is used to conditionally add extra
2972 files or directories to the specific distribution. Affected
2973 files ./prepare, Makefile.am.pre and distributions.
2975 Removed the `_' from the start of the distribution names.
2978 * Added README.WIN32 for instructions to compile the Toolkit
2981 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Fixed a double free in disconnection in the server. Affected
2984 file is silcd/server.c.
2986 * Fixed the lib/silcske/groups.c to work now also with GMP
2987 MP library. The string conversion did not work when using
2988 specific base and the base is indicated in the string as well.
2990 * Created win32/ directory which now includes MSVC++ specific
2991 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2992 It will appear only in the toolkit distribution
2994 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2996 * Changed the key material distribution function in case when
2997 the hash output is too short. The data is now concatenated
2998 a bit differently than it used to. Made the change to the
2999 SKE protocol specification.
3001 * Added better GMP detection to configure.in.pre. A patch
3004 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Fixed a minor bug in SKE that might cause some problem on
3007 some platforms. Affected file lib/silcske/silcske.c.
3009 * Added the cookie checking for initiator in the SKE. It checks
3010 that the responder returns the sent cookie unmodified. The
3011 affected file is lib/silcske/silcske.c. Added new SKE
3012 error type INVALID_COOKIE that can be sent during the
3013 negotiation. Fixed some memory leaks as well.
3015 * Added the "invalid cookie" error message to Irssi SILC client's
3018 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * Added `task_max' field to the SilcClientParams to indicate
3021 the maximum tasks the scheduler can handle. If set to zero,
3022 default values are used. Affected file lib/silcclient/silcapi.h.
3024 * Fixed memory leaks in silc_client_close_connection. Affected
3025 file lib/silcclient/client.c.
3027 * Added silc_client_del_client_entry to client library to free
3028 all memory of given client entry. Affected file is
3029 lib/silcclient/idlist.[ch].
3031 * Added new functions silc_client_del_channel and
3032 silc_client_del_server to delete channel and server entries.
3033 Affected file lib/silcclient/[silcapi.h/idlist.c].
3035 * Removed silc_client_del_client_by_id from silcapi.h.
3037 * Fixed the INFO command to return the server's own info
3038 correctly when querying by Server ID. Affected file is
3041 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Removed the non-blocking settings in WIN32 code in the
3044 silc_sock_[read/write] and added SleepEx instead. Affected
3045 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3046 of input data is now checked with FIONREAD and ioctlsocket.
3048 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Call silc_schedule_task_del_by_context in the
3051 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3052 Affected file lib/silccore/silcprotocol.c.
3054 * Call silc_protocol_cancel for active protocols in the
3055 silc_server_close_connection if the funtion
3056 silc_server_free_sock_user_data has not been called.
3057 Affected file silcd/server.c.
3059 * Generic tasks cannot be deleted using the del_by_fd
3060 task deleting function since generic tasks does not match
3061 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3063 * Added a notion to SILCOPER help file that the SILCOPER works
3064 only on router server, not on normal server.
3066 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Added for WIN32 support for the new scheduler as well.
3069 Affected file lib/silcutil/win32/silcwin32schedule.c.
3071 * Fixed the SHA1 implementation to work on various platforms.
3073 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3076 API. It is part of the scheduler now. Everything else is
3077 as previously but some functions has changed their names.
3078 Checkout the lib/silcutil/silcschedule.h for the interface.
3079 Updated all applications to use the new interface. Affected
3080 files are lib/silcutil/silcschedule.[ch].
3082 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Found a bug in the SKE implementation. The HASH value,
3085 specified by the protocol, was not computed correctly. The
3086 public key of the responder was not added to the computation
3087 even though it is mandatory. Affected file lib/silcske/silcske.c.
3088 This unfortunately causes incompatibilities with older
3089 clients and servers.
3091 * Added WIN32 specific network init and uninit functions:
3092 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3093 the Winsock2. Affected file lib/silcutil/silcnet.h and
3094 lib/silcutil/win32/silcwin32net.c.
3096 * Set the socket always to nonblocking mode on WIN32 after
3097 reading data or writing data. Affected file is
3098 lib/silcutil/win32/silcwin32sockconn.c.
3100 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Fixed various compilation problems under WIN32. Affected
3103 files lib/silcutil/win32/silcwin32thread.c and
3104 lib/silcutil/win32/silcwin32schedule.c.
3106 * Removed all _internal.h #includes from public header
3107 files. Internal headers must never be included from
3110 Removed also the lib/silcske/payload_internal.h file.
3112 * All include files that may be needed (public and some others
3113 included by the public headers) by application developers are
3114 now copied to the ./includes directory. It does not copy any
3115 internal headers. Affected file Makefile.defines.pre and all
3116 Makefile.am's under lib/ and subdirs.
3118 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * Do not change the ~/.silc directory's permissions automatically.
3121 Affected file irssi/src/silc/core/clientutil.c.
3123 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Do not cancel the protocol in silc_server_close_connection
3126 it might cause recursion. Now cancelled in the function
3127 silc_server_free_sock_user_data. Affected file silcd/server.c.
3129 * Fixed the silc_server_remove_clients_by_server to regenerate
3130 the channel keys correctly finally. Added also new function
3131 silc_server_remove_clients_channels to actually do it.
3132 Affected file silcd/server.c.
3134 * Fixed the silc_server_new_channel to not crash by giving
3135 wrong router to the new channel. Affected file is
3136 silcd/packet_receive.c.
3138 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3141 which is given as argument to the silc_client_alloc now.
3142 It can be used to configure the client and set various parameters
3143 that affect the function of the client.
3145 * The USERS command in server did not check whether the channel
3146 is private or secret. Affected file silcd/command.c.
3148 * Added new argument to the USERS command in protocol specification.
3149 The USERS command now can take the channel name as argument
3150 as well. Added support for this in client and server and
3151 updated the protocol specs.
3153 * Completed the GETKEY command in client. It can be now used
3154 to fetch also servers public key not only some clients.
3155 Affected files lib/silcclient/command[_reply].c.
3157 * Added silc_client_get_server to return server entry by the
3158 server name. Affected files lib/silcclient/silcapi.h and
3161 * Redefined the IDENTIFY command in protocol specification to be
3162 more generic. It now can be used to query information about
3163 any entity in the SILC Network, including clients, servers and
3164 channels. The query may be based either the entity's name
3165 or the ID. Added support for this in both client and server.
3167 Affected files silcd/command.c and lib/silcclient/command.c
3168 and command_reply.c.
3170 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3171 the _from_client and _from_server functions. Affected file
3174 * Added silc_client_get_channel_by_id_resolve to the file
3175 lib/silcclient/silcapi.h to resolve channel information by
3176 its ID. Added also silc_client_get_channel_by_id that
3177 does not resolve it from the server.
3179 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3181 * Added SilcServerEntry context into the client library
3182 to represent one server. The INFO command now allocates
3183 these to save the resolved server info. For now on the
3184 client library will also keep information about servers,
3185 connected and resolved with INFO.
3187 The INFO command now allocates the SilcServerEntry context
3188 and saves the server info there. The COMMAND_REPLY in
3189 the INFO now returns the parameters to application in
3190 same order as defined in the protocol specification.
3192 The entries are cached in the client->server_cache.
3194 * The INFO command is now issued after received the Client ID
3195 from the server. Affected file lib/silcclient/client.c.
3197 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3198 to the application as the mode changer might be server.
3199 It is guaranteed that NULL is not returned anymore to the
3200 application. Affected file lib/silcclient/client_notify.c.
3202 The ID Type is now also passed to the application so that
3203 it can check whether the returned entry is SilcClientEntry
3206 Added new function silc_client_get_server_by_id to return
3207 the server entry by ID. Affected files are the
3208 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3210 * Do not create the channel in the Irssi SILC Client when issuing
3211 the JOIN command but when received the sucessful JOIN command
3212 reply. Otherwise the channel might get created even though we
3213 could not join it. The Affected file is
3214 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3216 * Fixed a channel joining bug in router. The router must also
3217 check the channel modes, invite and ban lists etc. when serving
3218 the JOIN command sent by normal server. Affected file is
3219 silcd/command.c. The router now resolves the client's
3220 information from the server who sent the JOIN command if it
3221 does not know it, and processes the JOIN command only after
3224 * Changed the SilcCommandCb to take new argument; void *context2.
3225 Affected file lib/silccore/silccommand.h
3227 The second argument in the command callbacks in the server now
3228 includes the SilcServerCommandReplyContext if the command was
3229 called as pending command callback from the command reply.
3230 Otherwise it is NULL. When called as pending the status of the
3231 command reply will be checked and if it was erronous the
3232 error will be sent to the original sender of the command.
3233 This way the client always receives the error messages even
3234 though the server was actually the one who received the error
3235 when it resent the command to router, for example. Affected
3236 files silcd/command[_reply].[ch].
3238 * Fixed sending WHOWAS command's error message to client if
3239 the requested client could not be found. It was missing.
3242 * Changed the CMODE and CUMODE commands reply arguments in the
3243 protocol specification. The Channel ID is now sent in both
3244 of the commands to identify the channel. Implemented this
3245 new feature to the client and server. Affected files
3246 lib/silcclient/command_reply.c and silcd/command.c.
3248 * Made better checks for invite and ban lists in the JOIN
3249 command in server. Affected file silcd/command.c.
3251 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3253 * The server now performs the incoming host IP/DNS lookup
3254 using the silc_socket_host_lookup and thus does not block
3255 the server anymore. Affected file silcd/server.c.
3257 * Completed the multi-thread support for SILC Scheduler in
3258 the lib/silcutil/silcschedule.c.
3260 * Fixed the configure.in.pre to detect the pthread correctly
3263 * Fixed a deadlock in silc_task_queue_wakeup in the file
3264 lib/silcutil/silctask.c.
3266 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3268 * Added new function silc_schedule_wakeup that is used in
3269 multi-threaded environment to wakeup the main thread's
3270 schduler. It needs to be used when a thread adds a new task
3271 or removes a task from task queues. After waking up, the
3272 scheduler will detect the task queue changes. If threads
3273 support is not compiled in this function has no effect.
3274 Implemented the wakeup mechanism to both Unix and WIN32
3275 systems. Affected files are lib/silcutil/silcschedule.[ch],
3276 lib/silcutil/unix/silcunixschedule.c and the
3277 lib/silcutil/win32/silcwin32schedule.c.
3279 * Added new function silc_task_queue_wakeup to wakeup the
3280 scheduler by the specified task queue. Affected file
3281 lib/silcutil/silctask.[ch].
3283 * The silc_socket_host_lookup_start now wakes up the scheduler
3284 after adding the timeout task. Affected file is
3285 lib/silcutil/silcsockconn.c.
3287 * The silc_socket_host_lookup is synchronous now if the threads
3288 support is not compiled in. However, the callback is still
3289 called asyncronously through the scheduler, anyway. Affected
3290 file lib/silcutil/silcsockconn.c.
3292 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3294 * Added new function silc_socket_host_lookup to perform
3295 asynchronous IP and FQDN lookups for the socket connection.
3296 Affected files lib/silcutil/silcsockconn.[ch].
3298 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3300 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3301 that may or may not compile the mutex support in.
3303 Changed the silc_mutex_alloc interface. It allocates the
3304 mutex now to the sent pointer and returns TRUE or FALSE.
3306 Affected file lib/silcutil/silcmutex.h.
3308 * Wrote the SILC Task Queue interface to support multi-threads.
3309 Affected file lib/silcutil/silctask.[ch].
3311 * Wrote the SILC Scheduler to support multi-threads. Affected
3312 file lib/silcutil/silcschedule.c.
3314 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3317 in lib/silcutil/win32/.
3319 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Defined SILC Mutex API and SILC Thread API and implemented
3322 them for Unix. Affected files are
3323 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3324 lib/silcutil/unix/silcunixmutex.c and
3325 lib/silcutil/unix/silcunixthread.c.
3327 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Fixed the silc_server_remove_clients_by_server's channel
3330 key re-generation. The hash table handling was incorrect
3331 and would not work with many channels. Affected file is
3334 * Fixed some memory leaks around the server code.
3336 * Rewrote the silc_server_get_users_on_channel to support IPv6
3337 based Client ID's. Affected file silcd/server.c.
3339 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3340 specification. However, a separate document must be written
3341 to define the detailed signing procedure and the payload
3342 associated with the flag. Defined the flag to the
3343 lib/silccore/silcchannel.h as well.
3345 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Changed the dynamic tables to static size tables in the
3348 lib/silccrypt/silchmac.c.
3350 * Removed GCC dependencies from the code. A patch by cras.
3352 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Do not show the error "Error receiving packet bla bla"
3355 in server if it really was not an error (-2 means that reading
3356 is pending). Affected file silcd/server.c.
3358 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Fixed a possible crash in silc_server_remove_clients_by_server
3361 in silcd/server.c. Fixed there also some memory leaks.
3363 * Fixed the silc_idlist_replace_client_id. It could replace
3364 wrong key in the hash table. Affected file silcd/idlist.c.
3366 * Do not check whether there are global users on the channel
3367 if the channel->global_users is FALSE. Affected functions
3368 silc_server_remove_from_one_channel and
3369 silc_server_remove_from_channels in silcd/server.c. Also,
3370 do not check if the removed client is local as we can be
3371 sure that global client was not removed from the channel
3372 and checking for global users is not needed.
3374 * The silc_server_remove_clients_by_server now re-generates
3375 the channel keys correctly for those channels that had
3376 clients removed from them. Affected file silcd/server.c.
3378 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3380 * Found the reason of random crashes in the server. We weren't
3381 ignoring the SIGPIPE signal (which can be sent in write())
3382 and it crashed the server. Affected file silcd/silcd.c.
3384 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Assure that sock->user_data is not NULL in the function
3387 silc_server_packet_send in silcd/packet_send.c.
3389 * Disconnect the remote connection if it could not be added
3390 to any ID lists in the server. The affected file is
3393 * Check in silc_server_packet_send[_real/dest] that the
3394 socket is not disconnecting and ignore the data if it is.
3395 Affected file silcd/packet_send.c.
3397 * Define inline to __inline on native WIN32 compilation.
3398 Affected file includes/silcwin32.h.
3400 * Added some explicit type casts for inline code since MSVC
3401 require them. Affected files lib/silcutil/silcbuffer.h,
3402 lib/trq/silcdlist.h and lib/trq/silclist.h.
3404 * Print warning in log files from now on if the packet
3405 decryption fails. Affected file silcd/server.c.
3407 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Changed the `say' client operation's interface to accept
3410 new `type' argument to indicate the type of the message sent
3411 by the library. The application may filter the library's
3412 messages according the type. The affected file is the
3413 lib/silcclient/silcapi.h.
3415 * Added two new functions to lib/silcclient/silcapi.h:
3416 silc_client_del_client and silc_client_del_client_by_id.
3417 Affected file lib/silcclient/idlist.c.
3419 * Moved the clientincludes.h from includes/ to silc/ and
3420 serverincludes.h from includes/ to silcd/.
3422 * The modes for the CMODE and CUMODE are now passed as
3423 uint32 for application with COMMAND_REPLY. The affected
3424 file is lib/silcclient/command_reply.c.
3426 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * /WHOIS without arguments shows client's own information.
3429 Affected file lib/silcclient/command.c.
3431 * Changed PING to not accept any arguments. The specs
3432 says that client can ping only the connected server so
3433 requiring an argument is not needed. Affected file is
3434 lib/silcclient/command.c.
3436 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Fixed a fatal bug in private message sending and reception
3439 encryption and decryption when using private message keys.
3440 The implementation was incorrect and did not follow the
3441 specification. It causd that some of the message were
3442 lost since it did not use the sending and receiving keys
3443 as the protocol suggests. This has been fixed and will cause
3444 incompatibilities with older clients when sending private
3445 message encrypted with private message keys. Affected files
3446 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3447 and various other in Irssi SILC Client.
3449 Added `responder' boolean argument to the functions
3450 silc_client_add_private_message_key[_ske] to indicate when
3451 the key is added as responder or initiator of the key
3454 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Removed the silc_ske_check_version function and created
3457 a SilcSKECheckVersion callback. Added also a function
3458 silc_ske_set_callbacks that is now used to set all SKE
3459 callbacks. The callback functions are not given to
3460 the SKE functions anymore, but this function is used to
3463 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3465 * Added `silc_version' argument to the silc_client_alloc
3466 to define the version of the application for the library.
3467 The library will use the version string to compare it
3468 against the remote host's (usually a server) version
3469 string. Affected file lib/silcclient/silcapi.h
3471 * Added the KE protocol context to Key Agreement context
3472 in client library so that we can abort the SKE if it
3473 is in process when we get timeout. Affected file is
3474 lib/silcclient/client_keyagr.c.
3476 * Do not resolve the client ID forever if it returns in the
3477 first time that such client does not exist. This was done
3478 for example with private message. Affected file is
3479 lib/silcclient/client_prvmsg.c.
3481 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3483 * Do not add regex.h for WIN32. The affected file
3484 includes/silcincludes.h.
3486 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3487 not work yet 100%. It generates the DLL's automatically
3488 when compiling with --with-win32 under cygwin.
3490 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * lib/contrib/regex.c is not compiled on WIN32.
3494 * Added silc_net_get_socket_opt function to the
3495 lib/silcutil/silcnet.h.
3497 * Added includes/silcwin32.h for WIN32 specific includes
3500 * Do not use ptime structure or any of the posix process
3501 functions on WIN32 in lib/silccrypt/silrng.c.
3503 * Added silc_gettimeofday to provide generic function
3504 for struct timeval on all platforms. Added the function
3505 to lib/silcutil/silcutil.h.
3507 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3509 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3510 library as they clearly belong there. As a plus side we
3511 can make the actual socket connection routines platform
3514 Added also new generic function silc_socket_read and
3515 silc_socket_write (that used to be silc_packet_[read/write].
3516 The implementation of these are platform specific.
3518 * Added WIN32 specific routines of silc_socket_[read/write]
3519 to lib/silcutil/win32/silcwin32sockconn.c.
3521 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * Added preliminary support for native WIN32 compilation under
3524 cygwin (using the -mno-cygwin option for GCC) to the
3525 ./configure.in.pre. The --with-win32 now prepares the
3526 compilation for native WIN32.
3528 * Rewrote the SILC Scheduler interface in the file
3529 lib/silcutil/silcschedule.h. The scheduler is now context
3530 based and does not have anymore any global static scheduler.
3531 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3532 and created lib/silcutil/win32 directory for WIN32 based
3535 * Added Unix specific network routines to the
3536 lib/silcutil/unix/silcunixnet.c and the old
3537 lib/silcutil/silcnet.c includes now only generic routines.
3539 Added WIN32 specific network routines to the
3540 lib/silcutil/win32/silcwin32net.c.
3542 * Added Unix specific utility functions from the
3543 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3545 * Added WIN32 SILC Scheduler to the file
3546 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3549 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Do not handle JOIN notify in the server if the target client
3552 is not registered (idata->registered == FALSE). The affected
3553 file is silcd/packet_receive.c.
3555 * Update the nickrec->founder in event_cumode in the Irssi SILC
3556 client. Affected file irssi/src/silc/core/silc-channels.c.
3558 * Fixed the CUMODE_CHANGE notify handling in the server when
3559 server and router are announcing their clients on channels.
3560 Now the mode changes are saved and notified correctly. The
3561 affected file is /silcd/packet_receive.c.
3563 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3564 They really did not replace the cache entry in the ID Cache.
3565 Now they do that. Affected file silcd/idlist.c.
3567 * Fixed the KICK notify handling in the Irssi SILC client to
3568 update the channel records so that the kicked client does not
3569 appear to be on the channel. The affected file is
3570 irssi/src/silc/core/silc-channels.c.
3572 * Always update the conn->current_channel when executing command
3573 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3575 * Fixed the KILL notify handling in Irssi SILC client to remove
3576 the killed client on all channels.
3578 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Fixed the silc_parse_command_line to remove extra spaces
3581 from the start and end of the arguments. Affected file is
3582 lib/silcutil/silcutil.c.
3584 * Cancel and free any active protocol in the function
3585 silc_server_close_connection. Affected file silcd/server.c.
3587 * Cancel and free any active protocol in the function
3588 silc_client_close_connction. Affected file is
3589 lib/silcclient/client.c.
3591 * Do not execute the KILL command for clients that are in
3592 history (ie. they are not in the network). Affected file is
3595 * Fixed KILL notify handling, client does not crash anymore.
3596 Affected file irssi/src/silc/core/silc-channels.c.
3598 * Reduced the default packet buffer size from 2048 to 1024 in
3599 lib/silccore/silcpacket.c.
3601 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3602 counter to the SKE context that is incresed when the SKE library
3603 performs async operation outside the library. If the outside
3604 process frees the SKE context and FREED status will be set
3605 and the library will detect after the sync operation that the
3606 libary is freed. The affected files are
3607 lib/silcske/silcske[_status].[ch].
3609 * Resolve the client entry information in the function
3610 silc_client_channel_message to assure that NULL pointer is not
3611 passed as client entry to the application. */
3613 * Fixed the task timeout calculation to assure that there is
3614 never negative timeouts. The affected file is
3615 lib/silcutil/silcschedule.c.
3617 * Fixed the channel user mode notification sending in server.
3618 It was sent point-to-point to the router (or to server by router)
3619 but it needs to be destined to a channel. The routines now
3620 supports sending the channel user mode notifys to the channels
3621 when announcing clients and channels. Affected files are
3622 silcd/server.c and silcd/packet_receive.c.
3624 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3625 It did not actually replace the old channel entry in the cache.
3626 Affected file lib/silcclient/client_notify.c.
3628 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Fixed a possible crash in silc_packet_send_prepare. It now
3631 assures always that there is enough space in the buffer and
3632 at the tail area of the buffer (for MAC).
3634 Fixed the inbound buffer reallocation in silc_packet_read.
3635 It was old code and did not handle the reallocation correctly.
3638 The affected file is lib/silccore/silcpacket.c.
3640 * Fixed buffer overflow in silc_parse_nickname in the file
3641 lib/silcutil/silcutil.c.
3643 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * make install generates new server keys only if there is not
3648 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3651 Added check that if the NOREPLY is set then we will not send
3652 the away message. This avoids infinite loop of away messages
3653 if both clients are away. The affected file is
3654 lib/silcclient/client_prvmsg.c.
3656 * Fixed client crash if /NICK was given without arguments.
3657 Affected file lib/silcclient/command.c.
3659 * Server does not send the invite list in INVITE command back
3660 to the client if the list was not altered. Added this notion
3661 to the protocol spec as well. Affected file silcd/command.c.
3663 Fixed possible crash in INVITE command by checking the
3664 value of silc_server_get_client_route command.
3666 * Fixed the INVITE notify type handling. The arguments are now
3667 taken in correct order and client does not crash. The affected
3668 file is irssi/src/silc/core/silc-channels.c.
3670 Removed the "Inviting xxx to channel" message from the
3671 client library away and let the application handle it.
3672 Affected file lib/silcclient/command.c. Added that message
3673 to Irssi SILC client's message formats.
3675 * Fixed CMODE command crash in client. It now checks the
3676 amount of arguments correctly and does not crash. The affected
3677 file is lib/silcclient/command.c.
3679 * Do not create new channel automatically in silc_channels_join
3680 but check whether the channel by that name already exists.
3681 Affected file irssi/silc/core/silc-channels.c.
3683 * Do not send the SERVER_SIGNOFF to router if the disconnected
3684 entity was the router. Affected file silcd/server.c.
3686 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3687 SILC client as it was missing from there.
3689 Added the handling of the KICK notify to the Irssi SILC client
3690 as it was missing. Added "you have been kicked" message to
3691 Irssi SILC client's message modules formats.
3693 Added the handing of the KILL notify to the Irssi SILC client
3694 as it was missing. Added the kill message module formats
3697 The affected file is irssi/src/silc/core/silc-channels.c.
3699 * The router did not save the channel mode the server announced.
3700 Affected file silcd/packet_receive.c.
3702 * Fixed a possible crash in INFO command in server. If the
3703 server did not provide the server info it crashed. Affected
3704 file silcd/command.c.
3706 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Fixed the GETKEY command in the server to check also the
3709 global list. Otherwise the GETKEY would not work correctly
3710 in normal SILC server. Affected file silcd/command.c.
3712 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Fixed GETKEY crash, it crashed if the command did not succseed.
3716 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3719 is now real and not just an macro interface to GMP.
3721 Removed the entire GMP from the source tree and imported new
3722 NSS MPI library instead. Reason for removing GMP is that it is
3723 extremely large and compiles extremely slow. The NSS MPI
3724 is only a few files and compiles in less than 10 seconds.
3725 The speed is also about the same as GMP. The MPI is imported
3726 to lib/silcmath/mpi.
3728 If the system has GMP installed we will still use the GMP.
3729 If it is not then the NSS MPI will be compiled.
3731 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Merged a long nickname (127 characters long) crash bugfix from
3734 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3736 * Merged a freed memory reference bugfix from Irssi CVS tree.
3737 Affected file irssi/src/core/commands.c.
3739 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Added the server's public key sving and verification to the
3742 server when performing the SKE. This was missing and the
3743 remote server's (or router's) public key was accepted without
3744 checking whether we have it previously or trust it at all.
3745 Affected file silcd/protocol.c.
3747 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Check in the silc_server_timeout_remote if protocol is active
3750 and make sure that the protocol's final callback is called so
3751 that all memory if freed. Affected file silcd/server.c.
3753 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * silc_server_whois_send_reply crashed the server if the nickname
3756 was 127 characters long. Affected file silcd/command.c.
3758 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Added sanity check to the silc_server_new_client. If the hostname
3761 is provided inside username then check that the provided hostname
3762 really is the same as the resolved one. If the hostname was not
3763 resolved then check it from the public key. Affected file is
3764 silcd/packet_receive.c.
3766 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3767 if the server disconnected us and the connection is not valid
3768 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3770 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3771 the library to the lib/silcutil/silcutil.[ch].
3773 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Close log file after open. Affected file
3776 lib/silcutil/silclog.c.
3778 * Check whether sock == NULL in silc_client_send_packet and return
3779 if it is. Affected file lib/silcclient/silcclient.c.
3781 * Check rec->entry == NULL in the Irssi SILC Client before
3782 sending the channel message. Affecte file is
3783 irssi/src/silc/core/silc-servers.c.
3785 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Merged a splitted window bugfix from Irssi CVS tree. The
3788 affected file is irssi/src/fe-text/textbuffer-view.c.
3790 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3791 It did not print nickname.
3793 * Improved the distributions system a bit.
3795 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3798 irssi/src/fe-text/gui-window.c.
3800 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3801 to in-active server. The affected file is
3802 irssi/src/silc/core/client_ops.c.
3804 * Resolve the client in USERS command reply if the entry does
3805 not have username resolved. The affected file is
3806 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3807 command to WHOIS command to really resolve stuff. The USERS
3808 is not used any more in any critical section so WHOIS can
3809 be used even though it might be slower than IDENTIFY.
3811 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3814 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Changed the protocol API a bit more consistent in the
3817 lib/silccore/silcprotocol.[ch].
3819 * Changed the following headers to ROBODoc format:
3821 lib/silccore/silcpayload.h
3822 lib/silccore/silcprotocol.h
3823 lib/silccore/silcsockconn.h
3825 All core library headers are now formatted.
3827 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Fixed a bug in Irssi SILC client; do not show that you are
3830 server/router operator if you really are not. Affected file is
3831 irssi/src/silc/core/client_ops.c.
3833 * Renamed silc_command_free_payload to silc_command_payload_free.
3834 Affected file lib/silccore/silccommand.h
3836 * Added silcmath.h to include the prototoypes of various routines
3837 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3840 * Changed the following headers to ROBODoc format:
3842 lib/silccore/silcchannel.h
3843 lib/silccore/silccommand.h
3844 lib/silccore/silcid.h
3845 lib/silccore/silcidcache.h
3846 lib/silccore/silcmode.h
3847 lib/silccore/silcnotify.h
3848 lib/silccore/silcpacket.h
3849 lib/silcmath/silcmath.h
3851 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Added checking to the server code not to start the server if
3854 ciphers and stuff are not configured properly. Affected files
3855 silcd/serverconfig.[h] and silcd/server.c.
3857 * Changed the layout of the header files of the public interfaces
3858 in the SILC libraries. The new layout supports ROBODoc
3859 documentation tool (and some others) so that it is easy to create
3860 a library reference manual. All the other headers and source
3861 code must still follow the CodingStyle document. Also source
3862 code must not include these ROBODoc stuffs, only the headers.
3863 Furthermore, all public interface headers must now be named
3864 by using `silc' prefix, example: silcapi.h, silccipher.h.
3865 Some files were renamed due to this. All the other headers
3866 must not be used as public interfaces. I will update the
3867 CodingStyle document later. Changed following headers, so far:
3869 lib/silcclient/silcapi.h
3870 lib/silccore/silcauth.h
3871 lib/silccore/silcprivate.h
3872 lib/silccrypt/silcdh.h
3874 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Removed silc_client_packet_send_flush from the client library
3879 as it is not needed. Affected file lib/silcclient/client.[ch].
3881 * Added printing of message of unresolved authentication method
3882 to the Irssi SILC client. Added it to the module formats.
3883 Removed the same message from the client library.
3885 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Added new distribution feature, DISTLABEL. Every distribution
3888 can define own preprocessor label that can be used in the
3889 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3890 file distributions, acconfig.h.pre and prepare.
3892 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * Added Makefile.defines_int to include the actual definitions
3895 for Makefile.defines.in. Tested the new distribution system,
3896 created distributions and tested installation.
3898 * Added AWAY message printing to the Irssi SILC client. Added
3899 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3901 * Added SCONNECT command to call the SILC's CONNECT command.
3902 Cannot use CONNECT directly since Irssi uses that internally.
3903 Affected file irssi/src/silc/core/silc-servers.c.
3905 Added ACTION local command. It is same as ME command but takes
3906 the channel as mandatory argument.
3908 Rewrote some of the Irssi's help files to suite for SILC
3911 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Added Makefile.defines[.in] that should for now on be included
3914 in all Makefile.am file in the source tree. That file includes
3915 all common compilation definitions for SILC source tree.
3917 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Minor changes to the ./prepare script to change the package
3920 name according the distribution name to the configure.in.
3922 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Created new distribution system. Added file `distributions'
3925 that defines all the distributions that can be created out of
3926 the SILC source tree. The ./prepare script now reads that
3927 file to determine how to prepare the distributions. The
3928 first argument to the ./prepare is the name of the distribution
3929 and second is the version of the distribution. If given
3930 without arguments it creates the default (toolkit) distribution
3931 with the default version (defined in ./prepare).
3933 All Makefile.am files that are subject to the distributions
3934 are now named as Makefile.am.pre. These are ./Makefile.am
3935 and lib/Makefile.am. Others may be changed later.
3937 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Added invite list, ban list, some key management and connection
3940 error message printing to module formats in the Irssi SILC client.
3942 * Added new silc_client_set_away_message to set the away message
3943 that is back to the person who sent private message. The
3944 affected file lib/silcclient/silcapi.h and the
3945 lib/silcclient/client_prvmsg.c.
3947 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Fixed the private message sending in the Irssi SILC client,
3950 added local command KEY to the Irssi SILC client.
3952 Added key management and key agreement message formats to the
3953 irssi/src/fe-common/silc/module-formats.[ch].
3955 Added USERS (alias WHO) printing, server/router operator
3956 indication and LIST command printing to the module formats.
3958 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Fixed channel joining notify handling, cumode notify handling
3961 from Irssi SILC client.
3963 * Added SILC specific module-formats to the Irssi SILC client so
3964 that SILC specific message hilighting, colors etc is possible.
3965 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3967 Added channel mode, channel user mode, actions, notices,
3968 whois and whowas printing to the the module-formats.c.
3970 * Fixed a bug in channel deletion in the server. The channel
3971 is not left to the cache even if the channel founder auth mode
3972 is set when there are no users anymore on the channel. Affected
3973 file silcd/server.c.
3975 * The silc_net_localhost now resolves the entire hostname including
3976 the domain name. Affected file lib/silcutil/silcnet.c.
3978 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Changed the ask_passphrase client operation to be ascynchronous.
3981 It has now a completion callback and a context that the
3982 application must call after it has got the passphrase from
3983 the user. Affected files lib/silcclient/silcapi.h,
3984 lib/silcclient/protocol.c, lib/silcclient/command.c and
3987 Added SilcAskPassphrase callback that the application calls
3988 to deliver the passphrase to the library.
3990 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3991 The public key verification and especially a certificate
3992 verification is asynchronous procedure.
3994 Added new SILC_SKE_STATUS_PENDING status to indicate the
3995 request is pending and a callback will be called to finalize
3998 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3999 indicate that remote end did not send its public key (or
4000 certificate), even though we require it. Added check for this
4001 condition in the SKE. This was a security bug, now fixed.
4003 Defined new SilcSKEVerifyCbCompletion callback that is called
4004 when the verification process is completed.
4006 The affected files lib/silcske/silcske_status.h and
4007 lib/silcske/silcske.[ch].
4009 * Changed the verify_public_key client operation to be async
4010 as well. Defined SilcVerifyPublicKey callback that is used to
4011 indicate the success of the public key verification process.
4013 Changed the server and client to use the new async client
4016 * Changed the Irssi SILC client's internal scheduler to be called
4017 twice as many times as it used to be. As a result the client
4018 should be a bit faster now. Affected file is
4019 irssi/src/silc/core/silc-core.c.
4021 * Added support to Irssi SILC client of asynchronous public key
4022 verification and passphrase inquiry. Affected file is
4023 irssi/src/silc/core/silc-core.c.
4025 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Do not say "You have left channel %s" in client library.
4028 Moved it to the application. Affected files are
4029 lib/silcclient/command.c and silc/client_ops.c.
4031 * Fixed silc_client_get_clients. Command context was not
4032 duplicated and was freed memory in the callback. Affected
4033 file lib/silcclient/idlist.c.
4035 * Do not say "you are now talking..." on JOIN command in the
4036 client library. The appliation must handle it.
4038 * Do not say ".. changed topic to" in command reply in the
4039 client libary. The application must handle it.
4041 * Fixed TOPIC command sending in the client library.
4043 * Fixed a memory leak in silc_client_command_free in the file
4044 lib/silcclient/command.c.
4046 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Imported a modified version of Irssi client to the source tree.
4049 The Irssi will be used to create a new client called
4050 Irssi SILC. Imported to irssi/.
4052 Added silc_core_init_finish function to the Irssi. Affected
4053 file irssi/configure.in.
4055 A lot changes in the Makefile.ams around the irssi tree.
4057 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Do not rehash if the new size is same as the old size of the
4060 hash table, in the silc_hash_table_rehash*. The affected file
4061 lib/silcutil/silchashtable.c.
4063 * Replaced hash_table_del_by_context calls from the server
4064 (when channel->user_list and client->channels) to the
4065 hash_table_del as it is sufficient and faster.
4067 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Added silc_hash_table_list, silc_hash_table_get and the
4070 SilcHashTableList structure to provide an alternative way to
4071 traverse the hash table. The affected files are
4072 lib/silcutil/silchashtable.[ch].
4074 * Changed the server's idlist routines to use the hash table
4075 routines to optimize the code.
4077 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Replaced the client entry's `channel' list and channel entry's
4080 `user_list' list to hash tables for optimized lookup. Changed
4081 the code to use the hash table interface around the code.
4082 Affected file lib/silcd/idlist.[ch].
4084 * Added `auto_rehash' boolean argument to the function
4085 silc_hash_table_alloc to indicate whether the hash table should
4086 auto-rehash when it thinks is appropriate time. It will
4087 increase the hash table size if the there is twice as much
4088 entries in the table than the size of the table, and will
4089 decrease the size if there are twice as less entries than
4090 the size of the table.
4092 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4096 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * silc_idcache_purge_by_context deletes the entry now by context
4099 as it is supposed to do. Affected file lib/silccore/idcache.c.
4101 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4102 client is not anymore valid (WHOWAS givens the info) and not
4103 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4105 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Removed the `data' and `data_len' arguments from the ID Cache
4108 interfaces and added `name' argument. ID Cache does not handle
4109 anymore the binary data only a names associated with given ID.
4111 * When hashing a Client ID with silc_hash_id the entire ID is
4112 not hashed anymore, instead only the hash of the Client ID is
4113 hashed. This way we can access the Client ID from the cache
4114 with Client ID but with the hash of the ID (which is a hash of
4115 the nickname) as well without any difference in performance.
4117 Added also silc_idcache_find_by_id_one_ext to do one on one
4118 searching when we have the actual ID. Added also function
4119 silc_hash_client_id_compare. The affected files are
4120 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4122 * When hashing the name associated with a ID it is always done
4123 in lowercase. This way we can access the cache without worrying
4124 about case-sensitivity, even though, for example nicknames are
4127 * Fixed a bug in server with channel message sending. It put
4128 wrong ID type as destination ID. The affected file
4129 silcd/packet_send.c.
4131 * silc_idcache_del_by_context now deletes from all hash tables
4132 by context. Affected file lib/silccore/idcache.c.
4134 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Changed the client library to use the new ID Cache interface.
4137 Changes around the source tree.
4139 * Added silc_hash_table_rehash_ext to rehash with specific
4140 hash function. Affected file lib/silcutil/silchashtable.[ch].
4142 * Added silc_hash_string_compare to compare two strings in the
4143 hash table. Affected file lib/silcutil/silcutil.[ch].
4145 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Added new function silc_idcache_del_by_context into the
4148 lib/silccore/idcache.[ch].
4150 * Changed the server's ID list routines to use the new ID Cache
4151 interface. Changes around the source tree.
4153 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Added silc_hash_table_del[_by_context]_ext functions in to the
4156 lib/silcutil/silchashtable.[ch].
4158 Removed silc_hash_table_find_all* routines and added new
4159 silc_hash_table_find_foreach to replace them.
4161 Added silc_hash_table_replace_ext function as extended
4162 replacing function. Separated the simple hash table interface
4163 from the extended hash table interface in the file
4164 lib/silcutil/silchashtable.h.
4166 * Fixed minor bugs and changed it to use some of the new
4167 hash table functions in lib/silccore/idcache.c
4169 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Added new function silc_hash_table_find_all to return all keys
4172 in the hash table by the specified key. As the hash table is
4173 collision resistant it also makes it possible to have several
4174 duplicate keys in the hash table. This function may be used to
4175 find all of the keys from the hash.
4177 Added user_context arguments to the SilcHashFunction,
4178 SilcHashCompare and SilcHashDestructor to deliver user specified
4181 Added new fuctions silc_hash_table_find[_all]_ext to do
4182 extended lookup with specified hash and compare functions and
4183 specified user contexts.
4185 Added new function silc_hash_table_add_ext to add the key
4186 with specified hash function and user context.
4188 Added new function silc_hash_table_foreach to traverse all
4189 entrys in the hash table. Added SilcHashForeach callback
4192 Added new function silc_hash_table_del_by_context to delete
4193 the entry only if the context associated with the key matches.
4195 Affected files are lib/silcutil/silchashtable.[ch].
4197 * Removed silc_hash_[server/client/channel]_id and added just
4198 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4199 silc_hash_id_compare to compare two ID's using as the hash table
4200 comparison function. Added also silc_hash_data to hash
4201 binary data and silc_hash_data_compare to compare it.
4203 * Removed silc_idlist_find_client_by_hash as it is not needed
4204 anymore. Affected file silcd/idlist.[ch].
4206 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4207 to use internally the SilcHashTable. The new ID Cache is a lot
4208 faster than the old one. Some of the ID Cache interface was also
4209 rewritten and obsolete and stupid functions were removed.
4211 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Added entry_count field to the SilcHashTable to keep the number
4214 of the entries in the table. Implemented the function
4215 silc_hash_table_rehash. Added new function
4216 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4218 Fixed a minor bug in silc_hash_table_free.
4220 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4221 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4222 into the lib/silcutil/silcutil.[ch].
4224 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Implemented a collision resistant hash table into the
4227 lib/silcutil/silchashtable[ch]. See the header and the source
4228 for the SilcHashTable API.
4230 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Merged dotconf version 1.0.2 into lib/dotconf.
4234 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Do not compile anything in lib/silcsim/* if the SIM support
4237 is not enabled. The tree should now compile without problems
4240 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Compiled the SILC under cygwin. Compiled and tested briefly
4243 without problems. More tests needed. The SIMs didn't compile
4246 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4248 * Fixed possible crash in silc_get_username in the
4249 lib/silcutil/silcutil.c.
4251 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Fixed a va_arg in silc/client_ops.c.
4255 * Oops, RC5 routines were named AES and caused some problems
4256 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4258 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Added new SilcIDIP structure into the lib/silccore/id.h and
4261 replaced the old `ip' fields from all SILC ID's to that type.
4262 This is a step towards IPv6 support.
4264 The silc_id_get_len takes now the ID as an extra argument.
4265 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4266 both IPv4 and IPv6 based ID's.
4268 The affected files are lib/silccore/id.[ch] and other files
4269 around the tree using these routines.
4271 * Removed the ID length arguments in server from various
4272 silc_server_send_notify_* routines -> they are not needed
4275 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Fixed memory leak in silc_encode_pem_file in the file
4278 lib/silcutil/silcutil.c.
4280 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Check minor version as well in the SKE. Affected files are
4283 silcd/protocol.c and lib/silcclient/protocol.c.
4285 * Added --identifier option to the server so that an identifier
4286 can be when creating the public key for the server. Affected
4287 file is silcd/silcd.c.
4289 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4290 lib/silccrypt/silcpkcs.c.
4292 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Register default ciphers and stuff when using -C option with
4295 the server. Affected file sildc/silcd.c.
4297 * Put back the servers public key filename format, it is better
4298 than the new one. For now, the client keys are saved with the
4299 new filename format. The affected file silc/client_ops.c.
4301 * Implemented the Cipher API for the rest of the ciphers that
4302 did not implement it or implemented it the wrong way.
4304 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Register default ciphers and stuff when using the -S option
4307 in the client. Affected file silc/silc.c. Same also when
4308 creating new key pair with -C option.
4310 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Fixed the silc_verify_public_key client operation function to
4313 save the public keys differently. The fingerprint is now
4314 used as filename and not the hostname. This way also the
4315 client keys are saved uniquely and not with hostnames. The
4316 affected file is silc/client_ops.c.
4318 * Trimmed the silc_hash_fingerprint function to remove extra
4319 whitespaces from the end of the fingerprint. The affected
4320 file is lib/silccrypt/silchash.c.
4324 * Added silc_cipher_register_default function to register all
4325 default ciphers. It can be used when configuration files
4326 does not exist and the application does not want any specific
4327 ciphers in any specific order.
4329 The SilcDList is now used as silc_cipher_list dynamically
4330 allocated cipher list. Removed the static list all together
4331 and now all ciphers must be allocated to the dynamic list.
4332 The silc_cipher_alloc routine was changed to check only the
4335 All silc_cipher_* routines that used to return int returns
4338 The affected files lib/silccrypt/silccrypt.[ch].
4340 * The same thing was done to silc_hash_* as for silc_cipher_*
4341 routines. Affected files lib/silccrypt/silchash.[ch].
4343 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4344 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4345 Added also silc_pkcs_[un]register[_default] functions.
4346 Removed the data_context from the PKCS API.
4348 * Added silc_hmac_register_default function to register default
4349 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4350 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4351 to unregister all hmacs at once.
4353 * Register the default ciphers, hash functions, PKCSs and HMACs
4354 if client's configuration file does not exist. The affected
4357 * The client did not load the hash functions from the SIM
4358 modules at all. Added support for this. Affected file is
4359 silc/clientconfig.c.
4361 * When decoding public key with silc_pkcs_public_key_decode, check
4362 the supported algorithm only if PKCS are registered. Affected
4363 file lib/silccrypt/silcpkcs.c. The same was done with the
4364 silc_pkcs_private_key_decode.
4366 * Fixed the SILC List routines to keep the list always in order.
4367 It used to change the list's order when traversing the list but
4368 not it preserves the order. Affected file lib/trq/silclist.h.
4370 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Added the client library to use the SilcSocketConnection's
4373 reference counter (by silc_socket_dup) to prevent the bug that
4374 the socket object may be freed underneath async operation.
4376 * The name resolv library checking fixes in the configure.in.pre.
4379 * Created new version of the protocol drafts for future
4380 development. The -03 drafts are the ones that will be changed
4381 in the trunk now and the -02 will remain as they are.
4383 * Send list of CUMODE notifys to the router when announcing
4384 the channel users to the router. Affected file silcd/server.c.
4385 If the router receiving channel founder CUMODE for a channel
4386 that already has channel founder it will send CUMODE notify
4387 to the sender to remove the channel founder rights from the
4388 announced client. Affected file silcd/packet_receive.c.
4390 * The CUMODE notify may now use Server ID as well as the entity
4391 who changes the mode. Updated protocool specs.
4393 * Updated INSTALL and README files.
4395 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * New web pages in the http://silc.pspt.fi. The pages was
4402 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Implemented the [DenyConnectin] config section in the server.
4405 Added silc_server_config_denied_conn to check whether incoming
4406 connection is denied. Affected file silcd/serverconfig.[ch].
4408 * Do not check the ports when checking the incoming configuration
4409 data if the port is 0, meaning any. Affected file is
4410 silcd/serverconfig.c.
4412 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Fixed buffer overflow in silc_string_compare in the file
4415 lib/silcutil/silcutil.c.
4417 * Fixed double free in silc_server_command_leave in the file
4420 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Fixed the version checking in the server. Affected file is
4425 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Fixed the configuration data fetching when accepting new
4428 connections in the server. Affected file silcd/server.c.
4430 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Added `sender_entry' argument to the function
4433 silc_server_packet_relay_to_channel so that we can check
4434 whether some destination actually belongs to the same route
4435 the sender belongs (ie, we must not resend the packet to the
4436 sender). Affected file silcd/packet_send.[ch].
4438 * Added `servername' field to the SilcClientEntry in the server
4439 to hold the name of the server where client is from. Affected
4440 file is silcd/idlist.h.
4442 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Moved the channel message encrypting in the router betwen
4445 router connections from silc_server_channel_message to the
4446 silc_server_packet_relay_to_channel since we want to check
4447 whether we have anybody channel before encrypting anything.
4448 Affected files silcd/packet_[receive/send].c.
4450 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Fixed the [AdminConnection] server config section to support
4453 multiple entries. Affected file silcd/serverconfig.c.
4455 * Added support into the server to check the validity of the
4456 incoming connection before executing any KE or authentication
4459 * The connection configuration is now saved to the KE and
4460 connection auth protocol contexts and not fetched anymore in
4461 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4463 * The local hosts listenning address and port is also resolved
4464 now when starting the server. We want to have the socket object
4465 to include the real address and port for the listener. Added
4466 new function silc_net_check_local_by_sock into the files
4467 lib/silcutil/silcnet.[ch].
4469 * Fixed a broadcast bug in server -> do not broadcast if we
4472 * Fixed a routing bug. Do not route broadcast packets ever.
4473 Broadcast packets must be processed always and not routed since
4474 they may be destined to some other host than yourself and thus
4475 would get routed without no good reason. Affected file is
4478 * Added function silc_server_config_is_primary_route to check
4479 whether primary router connection has been configured (a router
4480 configuration that we are initiating). If there is not, we
4481 will assume that there is only two routers in the SILC network
4482 and we will use the incoming router connection as our primary
4483 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4485 * Changed the order of the broadcasting. Broadcast _after_ the
4486 packet has been processed not before. Affected file is
4489 * Fixed a [ClientConnection] parsing bug. The port was never
4490 parsed correctly thus resulting to port 0. Affected file
4491 silcd/serverconfig.c.
4493 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4494 argument and did not set the broadcast packet flag. Affected
4495 file silcd/packet_send.c. Fixed same bug in the function
4496 silc_server_send_notify as well.
4498 * If we receive NEW_ID packet for our own ID in the server, ignore
4501 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Removed the nickname from the Private Message Payload.
4506 Updated the code and the protocol specs.
4508 * Updated protocol specs for submitting to the IETF.
4510 * Tweaked the Random Number Generator a bit. Affected file
4511 lib/silccrypt/silcrng.c. Exported a new function
4512 silc_rng_[global]_add_noise which can be used to add more
4515 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Do not parse packets with different timeout when protocol
4518 is active -> may cause problem with rekey. Affected file
4521 * When server receives signoff notify it must not create
4522 new channel key if the client is on any channels since the
4523 sender of the signoff notify will create it.
4525 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added printing of error messages during SKE protocol from the
4528 failure packet sent by server during SKE. Affected file
4531 * Removed the client's failure_callback handling with timeout
4532 and handle it immediately when received.
4534 * The SKE library returned wrong type in SUCCESS and FAILURE
4535 packets. They must be 32 bit MSB not 16 bit MSB.
4537 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Ok, rewrote the logic of the re-key and now it seems to work.
4540 I tested it on high traffic with frequent re-keys without
4541 problems. Added hmac_receive (and renamed hmac to hmac_send)
4542 in SilcClientConnection in lib/silcclient/client.h and
4543 in SilcIDListData in silcd/idlist.h. Also, removed the
4544 SilcPacketParserContext's cipher and hmac fields as they are
4545 not needed anymore and actually caused some problems when
4546 the ciphers and hmac's changed underneath the packet parser.
4548 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * If re-key protocol is active then process the incoming packets
4551 synchronously since we must assure that icoming packets encrypted
4552 with the old key is processed before the new keys is set to
4553 use. This is true other packets than for REKEY packets.
4554 Affected file silcd/server.c. The same was done to client library
4555 as well, affected file lib/silcclient/client.c.
4557 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Fixed bug in client and server to accept the force send if
4560 the packet is send from silc_[server/client]_packet_process
4561 function. Otherwise the packets are never delivered, oops.
4563 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Disable force sending of packets when REKEY protocol is active.
4566 We must assure that no packet is sent directly when rekey is
4567 performed. All packets must be sent through packet queue.
4568 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4569 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4570 function is silc_[server/client]_packet_send_real to check
4573 * Replaced the SIM paths from example config files to
4574 /usr/local/modules. Also, make install creates now
4575 /usr/local/silc/logs directory to hold all the SILC server
4578 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Made the configure.in.pre work on Solaris. Patch by salo.
4582 * Made all ciphers compatible with non-x86 machines. Defined
4583 CBC mode macros into lib/silccrypt/ciphers_def.h.
4585 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Fixed the make install.
4589 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * When MAC computation fails the silc_packet_decrypt returned 0
4592 even though it was supposed to return -1. Fixed this. The
4593 affected file is lib/silccore/silcpacket.c.
4595 * Do not replace the config files in /etc/silc (in make install)
4596 if they already exist. Affected file ./Makefile.am.
4598 * Do not send re-key packets immediately but through packet queue.
4599 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4601 * Changed silc_net_check_host_by_sock to return FALSE if the
4602 IP/DNS could not be resolved. Though, it returns the IP address
4603 now even if it could not resolve it (but returns also FALSE).
4604 Affected file lib/silcutil/silcnet.[ch].
4606 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Added silc_pkcs_decode_identifier to decode the public key's
4609 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4610 Added also silc_pkcs_free_identifier. Added also new context
4611 SilcPublicKeyIdentifier.
4613 * Added -S option to the silc client. It is used to dump the
4614 contents of the specified public key file.
4616 * Changed the PKCS api to return the public key length when
4617 setting the public key.
4619 * Fixed a fatal bug in the public and private key file loading.
4620 Affected file lib/silccrypt/silcpkcs.c.
4622 * Execute the packet parsing for client with zero (0) timeout
4623 if the protocol is active. Affected file silcd/server.c.
4625 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Made the key generation options to the silcd program. Added
4628 -C option, equivalent to client's option.
4630 * Added new [ServerKeys] config section to the server. It
4631 configures the server's public and private key.
4633 * Defined generic Public Key Payload into the protocol
4634 specification to send specific type of public keys and
4637 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4638 public key or certificate.
4640 * Implemented the GETKEY command to the server and to the
4641 client library and on user interface.
4643 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Made preliminary `make install' work.

4674 SilcClientConnection structure; not needed. Affected file is
4675 lib/silcclient/client.h.
4679 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Do not ask whether user wants to use the negotiated private key
4682 for private messages, just use it. Affected file is
4683 silc/local_command.c.
4685 * Added `send_enc_key' and `enc_key_len' fields to the
4686 SilcIDListData structure since they are needed in the re-key
4687 phase. Affected file is silcd/idlist.[ch].
4689 * Implemented the simple re-key protocol into the server.

4701 the PFS is to be performed in the re-key. Affected file is
4704 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4707 int64 of at least the xintXX size. If void * is less that 4
4708 bytes uint32 * will be used. Defined bool as boolean.
4710 * Changed _ALL_ unsigned long and unsigned int to uint32,
4711 unsgined short to uint16 in the source tree.
4713 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4714 not handle clients that has entry->data.registered == FALSE.
4715 They are not in the network anymore. Affected file is
4718 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Implemented the sending of the SERVER_SIGNOFF notify in the
4721 server. Affected file is silcd/server.c.
4723 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4724 Added also silc_notify_payload_encode_args into the

4727 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4728 Affected file silcd/packet_receive.c.
4730 * Implemented the SERVER_SIGNOFF notify handling in the client
4731 library. Affected file lib/silcclient/client_notify.c. Also,
4732 implemnted the printing of the SERVER_SIGNOFF info to the
4733 application. Affected file silc/client_ops.c.
4735 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4736 if the deleting was successful. Affected file silcd/idlist.[ch].
4738 * Added support for public key authentication in the connection
4739 authentication protocol in the client library. Affected file
4740 lib/silcclient/protocol.c.
4742 * Changed the server's silc_idlist_get_clients_by_* interface
4743 to support already allocated array so that new entries may be
4744 added to pre-allocated array. Affected file silcd/idlist.[ch].
4745 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4746 and command replies.
4748 * All command reply functions in the server now calls the
4749 pending command callback even if error occured. This way the
4750 error will be delivered to the client as well. Affected files
4751 silcd/command.c and silcd/command_reply.c.
4753 * Fixed INFO command to return local server's info if no server
4754 was provided. Affected file lib/silcclient/command.c.
4756 * Removed RESTART command for good. Updated the code and the
4759 * Rewrote parts of the task system. It is a bit simpler now.
4760 Removed unsued task priorities. The affected files are
4761 lib/silcutil/silctask.[ch].
4763 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Moved the USERS printing from the library to the application.
4766 Affected files lib/silcclient/command.c and silc/client_ops.c.
4768 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Added channel key re-key support. The re-key is perfomed
4773 only by the router and is done once in an hour. Added `rekey'
4774 field to the SilcChannelEntry in the server. Affected files
4775 silcd/server.c and silcd/idlist.h.
4777 * Added silc_task_unregister_by_context into the file
4778 lib/silcutil/silctask.[ch].
4780 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Added SILC_UMODE_GONE mode to indicate when the client is not
4783 present in the SILC network. Added also support to the local
4784 command AWAY that will set this mode. Added support of showing
4785 "xxx is gone" in WHOIS command. The USERS command shows the
4786 gone status as well.
4788 * Fixed setting server and router operator privileges in the
4789 server's UMODE command. Affected file silcd/command.c.
4791 * Merged the SKE KE1 and KE2 payloads into one payload. The
4792 new KE payload is equivalent to the old KE2 payload.
4794 Cleaned up the SKE Start Payload parsing. It now uses the
4795 simple buffer unformatting to do the parsing. A lot faster
4798 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4799 to the SKE that is used to indicate whether both of the SKE
4800 parties should perform authentication. By default only the
4801 responder performs authentication. By setting this flag also
4802 the initiator must do authentication. By default it is unset
4803 since in normal SKE case, client to server connection, only
4804 the responder should do authentication. When doing SKE between
4805 two clients both should perform authentication. Updated the
4806 code and the protocol specs.
4808 * A little fix to IDENTIFY command in the server. Search the
4809 client first by hash not nickname. Affected file is
4812 * Fixed the silc_client_close_connection to support closing
4813 the client to client connections wihtout deleting too much
4814 data. Affected file lib/silcclient/client.c.
4816 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4817 are received if protocol used to be active but is not anymore
4818 the application would crash due to NULL pointer dereference.
4819 Affected files silcd/server.c and lib/silcclient/client.c.
4821 * Added `hash' field to the SilcClientConnection to include
4822 the hash function negotiated in the SKE protocol.
4824 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4825 to set the channel founder authentication data. A client can
4826 claim the founder rights later by providing the authentication
4827 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4828 This way the channel founder can regain the channel founder
4829 privileges even it is left the channel. This works only on
4830 local server and the client must be connected to the same
4831 server to be able to regain the founder rights. Updated the
4832 protocol specs accordingly.
4834 Added support to the CMODE command in the client to set the
4835 founder auth data. Read the README to see how to set it.
4837 Added support to the CUMODE command to claim the founder
4838 rights. Read the README to see how to do it.
4840 Added support for the founder authentication to the Channel
4841 Entry in the server. Affected file silcd/idlist.h.
4843 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4844 server's CMODE command. Affected file silcd/command.c.
4846 * Added the following new functions into lib/silccore/silcauth.[ch]:
4847 silc_auth_get_method and silc_auth_get_data.
4849 * The server now saves the remote hosts public key to the
4850 SilcIDListData pointer. Affected file silcd/protocol.c.
4852 * The normal server now does not remove the channel entry from
4853 the cache if the founder authentication data is set. It used
4854 to remove it if the founder was the last one on the channel on
4855 the server and left the channel. The auth data is saved and
4856 if the channel is re-joined later the old entry is used with
4857 the old auth data. Affected files silcd/command_reply.c and
4860 * Removed the `pkcs' field from the SilcIDListData structure
4861 in the server; it is not used. Affected file silcd/idlist.h.
4863 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Fixed packet processing on slow links. Partial packets were
4866 never re-processed because the incoming data buffer was cleared
4867 by the application. Application must not directly clear the
4868 sock->inbuf, the packet processing routines handle it. Fixed
4869 this in client library and in server.
4871 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Fixed the WHOIS and IDENTIFY send reply function to really
4874 check whether to send list or just one entry. Affected file
4877 * Cleaned up the LEAVE command's channel key distribution. The
4878 affected file silcd/command.c.
4880 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4881 can enforce the channel mode as well. In that case the ID
4882 includes the ID of the server. The code now enforces the
4883 mode change if the router have different mode than the server.
4885 * The notify client operation with CMODE_CHANGE notify can now
4886 return NULL client_entry pointer if the CMODE was not changed
4887 by client. Application must check for this.
4889 * Added <Server ID> argument to INFO command to support server
4890 info fetching by Server ID.
4892 * Added silc_server_announce_get_channel_users to get assembled
4893 packets of channel users of the specified channel. Affected
4894 file silcd/server.[ch].
4896 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4897 was freed underneath the ID Cache.
4899 * Re-announce clients when the server received CHANNEL_CHANGE
4900 notify from the router. Affected file silcd/packet_send.c.
4902 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4905 crashed since it did not handle the fact that there is no cipher
4906 called "3" and didn't check the error condition. Now fixed.
4908 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4909 flag. It can be used to send message requests.
4911 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Implemented the RESTART command in the client.
4915 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4916 notice type messages. Added notice printing to the user
4919 * The channel keys are not re-generated if the channel's mode
4920 is PRIVKEY, ie private key on the channel exists. Affected
4921 files silcd/server.c and silcd/command.c.
4923 * Fixed a little bug in channel message delivery when channel
4924 private keys are set in the server. Affected file is
4925 silcd/packet_send.c.
4927 * Changed the setting on channel->on_channel = TRUE from the
4928 silc_client_save_channel_key to the JOIN command reply. The
4929 key payload is not received if the private channel key is set.
4930 Affected file lib/silcclient/command_reply.c and the
4931 lib/silcclient/client_channel.c.
4933 * When the CMODE_CHANGE notify is sent and the channel private
4934 key mode is removed the channel key must be re-generated in
4935 other cells as well. Added this support for the router in the
4936 silcd/packet_receive.c.
4938 * Added new local command NOTICE to send notice message on
4939 channel. Affected file silc/local_command.[ch].
4941 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Added new local command ME to the client. It is used to send
4944 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4945 some action. Affected file silc/local_command.[ch].
4947 * Changed channel_message and private_message client operations
4948 to deliver the message flags to the application. Added also
4949 the `flags' arguments to the silc_client_send_channel_message
4950 and silc_client_send_private_message functions. Affected file
4953 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Redefined the Private Message Payload to support private message
4956 keys and to support the new private message flags. Updated
4957 the protocol specs. Flags makes it possible to have for example
4958 CTCP style messages.
4960 * Added new type SilcPrivateMessagePayload and defined an API
4961 for it in the lib/silcclient/silcprivate.[ch].
4963 * Tested private message private keys successfully. Tested the
4964 private message key set, unset and list commands with the new
4967 * Redefined the Channel Message Payload to include the channel
4968 message flags (equal with private message flags) to support
4969 for example CTCP style messages.
4971 * Defined some of the message (for channel and private message)
4972 flags. Updated the protocol specs and added the flags to the
4973 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4975 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Added SilcKeyAgreementStatus type to the key agreement routines
4978 to indicate the current status and error if one occured.
4979 The status types are defined in the lib/silcclient/silcapi.h.
4981 * Added new local command KEY that is used to set and unset private
4982 keys for channels, set and unset private keys for private messages
4983 with remote clients and to send key agreement requests and
4984 negotiate the key agreement protocol with remote client. The
4985 key agreement is supported only to negotiate private message keys,
4986 it currently cannot be used to negotiate private keys for channels,
4987 as it is not convenient for that purpose.
4989 * Fixed a minor pending callback setting bug in the function
4990 silc_client_get_client_by_id_resolve, now the function works.
4991 Affected file lib/silcclient/idlist.c.
4993 * Added function silc_net_get_local_port to get local bound
4994 port by socket. Added to lib/silcutil/silcnet.[ch].
4996 * Added `sockets' and `sockets_count' fields to the SilcClient
4997 object. They hold the sockets of the listenning sockets in
4998 the client. Listenning sockets may be for example the key
4999 agreement server. Affected file lib/silcclient/client.[ch].
5000 Added functions the silc_client_add_socket and the
5001 silc_client_del_socket. They are exported to the application
5004 * Added ~./silc/clientkeys to support other client's public keys.
5006 * Renamed verify_server_key client operation to verify_public_key
5007 and added one argument to indicate the type of the connection
5008 (server, client etc.).
5010 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Added silc_server_connection_auth_request to handle the
5013 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5014 silcd/packet_receive.[ch].
5016 * Added silc_server_send_connection_auth_request into the
5017 silcd/packet_send.c to send the connection auth request packet.
5019 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5022 * Fixed the public key authentication in responder side in the
5023 server. The `auth_data' pointer includes the SilcPublicKey
5024 not the path to the public key. Affected file silcd/protocol.c.
5026 * Implemented the public key authentication in the initiator side
5027 in the server. Affected file silcd/protocol.c.
5029 * Removed the [RedirectClient] config section from the server
5030 configuration. Is not needed and I don't want to implement it.
5032 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Cleaned up the CMODE command in the server. It now works
5035 correctly and supports all the modes defined in the protocol.
5036 Affected file is silcd/command.c.
5038 * Added `hmac_name' field to the SilcChannelEntry in the server
5039 to hold the default HMAC of the channel. It can be set when
5040 creating the channel (with JOIN command). Affected files
5043 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5044 type to indicate the change of the current cipher and hmac
5045 on the channel. Client can safely ignore the <cipher> argument
5046 (if it chooses to do so) since the CHANNEL_KEY packet will
5047 force the channel key change anyway. The <hmac> argument is
5048 important since the client is responsible of setting the new
5049 HMAC and the hmac key into use.
5051 * Fixed the CMODE command in the client library as well.
5053 * Tested CMODE command in router environment successfully.
5055 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Show the version of the remote client (or server) when connecting
5058 to the server. It is logged to the log file. Affected file
5059 is silcd/protocol.c.
5061 * Fixed the KILLED notify handling in the client library. The
5062 client must be removed from all channels when receiving the
5065 Also, do not remove the client entry when giving the KILL
5066 command but when the KILLED notify is received.
5068 * Removed silc_idlist_find_client_by_nickname from the server.
5069 Not needed anymore. Affected files silcd/idlist.[ch].
5071 * Implemented the CHANNEL_CHANGE notify type handling to the
5072 server. Affected file silcd/server.c.
5076 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Added silc_server_send_notify_invite to send the INVITE
5079 notify between routers.
5081 * Implemented the INVITE command correctly to the server.

5090 * Added function silc_server_get_client_resolve to find the
5091 client entry by ID from all ID lists and then resolve it
5092 (using WHOIS) if it cannot be found. Affected file is
5095 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Implemented the BAN command to the client library.
5099 * The JOIN command in the server now checks the invite list
5102 * Changed the silc_command_reply_payload_encode_va and the
5103 silc_command_payload_encode_va to support that if argument is
5104 NULL it ignores and checks the next argument. Affected file
5105 lib/silccore/silccommand.c.
5107 * Added silc_server_send_notify_ban to send the BAN notify
5108 type between routers.
5110 * Chaned the silc_notify_payload_encode to support that if
5111 argument is NULL it ignores and checks the next argument.
5112 Affected file lib/silccore/silcnotify.c.
5114 * Tested ban lists in router environment successfully.
5116 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Implemented BAN command to the server, in silcd/command.[ch].
5120 * Removed the BAN and INVITE_LIST modes from the CMODE command
5123 * Added function silc_string_match to regex match two strings.
5124 Affected files lib/silcutil/silcutil.[ch].
5126 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Redefined parts of the SilcChannelEntry in the server to support
5129 the new ban and invite lists.
5131 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Redefined the INVITE command. The same command can be used to
5134 invite individuals to the channel but also to manage the invite
5135 list of the channel (to add to and remove from the invite list).
5136 Updated the protocol specs.
5138 * Added new command SILC_COMMAND_BAN that can be used to manage
5139 the ban list of the channel. Updated the protocol specs.
5141 * Removed the channel modes: the SILC_CMODE_BAN and the
5142 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5143 in the CMODE command. The equivalent features are now available
5144 using INVITE and BAN commands. Updated the protocol specs.
5146 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5147 in the network about change in the current ban list. The notify
5148 type is not used by the client.
5150 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5151 support the invite lists.
5153 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Added new function silc_string_regexify that converts string
5156 including wildcard characters into regex string that can
5157 be used by the GNU regex library. Added into the file
5158 lib/silcutil/silcutil.[ch].
5160 Added silc_string_regex_combine to combine to regex strings
5161 into one so that they can be used as one regex string by
5162 the GNU regex library. Added into the file
5163 lib/silcutil/silcutil.[ch].
5165 Added silc_string_regex_match to match two strings. It returns
5166 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5168 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Imported GNU regex to the soruce tree into lib/contrib.
5171 Fixed some compiler warning from the regex.c.
5173 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Fixed MOTD command in the server to work in router environment.
5177 * Fixed the MOTD command in the client library to support
5178 the server argument in the command.
5180 * Added `nickname_len' argument to the silc_idlist_add_client
5181 in the server, as the `nickname' argument may be binary data
5184 * Added silc_idlist_get_channels to return all channels from
5187 * Implemented LIST command to the server. Affected file is
5190 * Implemented the LIST command to the client library and on the
5193 * Added [<user count>] argument to the LIST command reply.
5194 With private channels the user count is not shown.
5196 * Updated TODO and README.
5198 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * The client entry's data.registered must be TRUE even with
5201 global client entry on global client list. The data.registered
5202 is used to check whether the client is anymore in the network,
5203 for example with WHOWAS command so it must be valid.
5205 * Fixed the WHOWAS command in the server. It now actually works
5206 in router environment. Added function into silcd/command_reply.c
5207 silc_server_command_reply_whowas_save.
5209 * Added silc_idlist_purge function to the silcd/idlist.c
5210 to periodically purge the ID Cache.

5220 they were buggy because of the WHOWAS information.
5222 * Fixed local command MSG to handle the async resolving of
5223 the remote client properly. It used to fail the first MSG.
5224 Affected file silc/local_command.c.
5226 * Added `data_len' field to SilcIDCache context.
5228 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Update TODO. Todo in commands in the server.
5232 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5235 used by routers as broadcast packet to inform other routers
5236 about the changed user mode.
5238 Implemented the notify handling in the server. Affected file is
5239 silcd/packet_receive.c. Added the function
5240 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5242 * Added new generic Channel Payload and deprecated the New Channel
5243 Payload. The New Channel Payload is now the generic Channel
5246 * Added new argument `mode' to the silc_server_send_new_channel
5247 as it is required in the Channel Payload now.
5249 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5250 and created a new and real SilChannelPayload to represent the
5251 new generic Channel Payload. Implemented the encode/decode
5252 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5254 * Added silc_server_get_client_channel_list to return the list
5255 of channels the client has joined for WHOIS command reply.
5256 Affected file silcd/server.[ch].
5258 * Implemented the channel list sending in the WHOIS command reply
5259 in server and in the client.
5261 Implemented the channel list displaying on the user interface
5262 as well. Affected file silc/client_ops.c.
5264 * Added silc_channel_payload_parse_list to parse list of Channel
5265 Payloads. It returns SilcDList list of SilcChannelPayloads.
5266 Client for example can use this function to parse the list of
5267 channels it receives in the WHOIS command reply. The caller
5268 must free the list by calling silc_channel_payload_list_free.
5269 Affected files lib/silccore/silcchannel.[ch].
5271 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Added one new argument <user mode> to the WHOIS command reply

5282 Affected file silc/client_ops.c.
5284 * Implemented the UMODE command and user modes in general to the
5285 client library and to the user interface.
5287 * Implemented the UMODE command to the server.
5289 * The server now sends UNKNOWN_COMMAND error status if client sends
5290 unknown command. Affected file silcd/command.c.
5292 * All server commands now handle the command identifier the right
5293 way when sending the command reply to the client. The client can
5294 use to identify the command replies with the identifier.
5296 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Added silc_server_get_client_route to resolve the route to
5299 the client indicated by the client ID. Affected file is
5302 * Added silc_server_relay_packet as general function to relay
5303 packet to arbitrary destination. This deprecates functions
5304 like _send_private_message_key, _relay_notify etc. Affected
5305 file is silcd/packet_send.[ch].
5307 Removed silc_server_send_key_agreement,
5308 silc_server_send_private_message_key and
5309 silc_server_packet_relay_notify functions from the file
5310 silcd/packet_send.[ch].
5314 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5315 server. Affected file silcd/packet_receive.[ch].
5317 * Implemented the KILL command to the client. Implemented the
5318 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5319 Affected files lib/silcclient/command[_reply].c and
5320 lib/silcclient/client_notify.c. Implemented the KILL notify
5321 printing in the user inteface.
5323 * Fixed a lot silc_parse_nick memory leaks from the client
5324 library in the file lib/silcclient/command.c.
5326 * Changed the silc_server_send_notify_on_channels's `sender'
5327 argument from SilcSocketConnection to SilcClientEntry to
5328 check the sender as entry and not as connection object and not
5329 to send to the client provided as argument. The affected file
5330 is silcd/packet_send.[ch].
5332 * The notify packets that are destined directly to the client used
5333 to not to be processed by the server. Now changed that and the
5334 server processes all notify packets. After relaying the packet
5335 to the client the notify packet is processed in the server.
5337 * The silc_server_free_client_data now checks whether there is
5338 pending outgoing traffic for the client and purges the data to
5339 the network before removing the client entry.
5341 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5344 an client is killed from the SILC Network. Updated the protocol
5347 Added new function silc_server_send_notify_killed to the
5348 silcd/packet_send.[ch].
5350 * Added function silc_server_packet_relay_notify to relay notify
5351 packets that are destined directly to a client. In this case
5352 the server does not process the notify packets but merely relays
5353 it to the client. Affected file silcd/packet_send.[ch].
5355 Added also silc_server_packet_process_relay_notify to check
5356 whereto relay the notify. Affected file is
5357 silcd/packet_receive.[ch].
5359 * Implemented the KILL command to the server.
5363 * Added the backup schema desgined last fall to the protocol
5364 specs for everyone to see. The specification is in the
5365 *-spec-xx.txt draft and the packet type definitions for the
5366 backup routers is in *-pp-xx.txt draft. Thusly, added also
5367 new packet type SILC_PACKET_CELL_ROUTERS.
5369 * A big security problem in the implementation discovered. The
5370 signoff of an client did not cause new channel key generation
5371 which it of course should've done. The channel keys must be
5372 always re-generated when client leaves (or signoffs) the channel.
5373 The silc_server_remove_from_channels funtion now handles
5374 the channel key re-generation.
5376 * Added `sender' argument to the silc_server_send_notify_on_channels
5377 to not to send the client provided as argument. Affected file
5378 silcd/packet_send.[ch].
5380 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Implemented OPER and SILCOPER commands into the server and
5385 * Added silc_auth_verify and silc_auth_verify_data to verify
5386 the authentication directly from the authentication payload.
5387 It supports verifying both passphrase and public key based
5388 authentication. Affected file lib/silccore/silcauth.[ch].
5390 * Added `hash' field to the SilcIDListData structure. It is the
5391 hash negotiated in the SKE protocol. Affected file is
5394 * Slight redesigning of the SilcAuthPayload handling routines.
5395 Do not send SilcPKCS but SilcPublicKey as argument.
5397 * Implemented the public key authentication support to the
5398 serverconfig. The public key is loaded from the provided path
5399 and saved as authentication data to void * pointer. Thus,
5400 changed the unsigned char *auth_data to void *auth_data;
5402 * Fixed SHUTDOWN command to send the reply before the server
5403 is shutdown. :) Affected file silcd/command.c.
5405 * Fixed fatal bug in CONNECT command. The hostname was invalid
5406 memory and server crashed. Affected file silcd/command.c.
5408 * Fixed fatal bug in CLOSE command. The server_entry became
5409 invalid but was referenced later in the command. Affected file
5412 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Fixed fatal bug in failure packet handling. Server ignored
5415 the failure and thus crashed when it came.
5419 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5422 that the command may be executed only once in (about) 2 seconds.
5423 The old SILC_CF_LAG flag is same but allows command bursts up
5424 to five before limiting.
5426 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5427 server code. Various commands now includes the CF_LAG_STRICT
5428 flag to disallow any kind of miss-use of the command.
5430 * Fixed the silc_buffer_unformat to not to allocate any data
5431 if the length of the data is zero. It used to allocate the
5432 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5434 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Changed the format of AdminConnection configuration section
5437 in the server. Added username of the admin to the format.
5438 Affected files silcd/serverconfig.[ch].
5440 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5441 to return admin configuration data by host, username and/or
5444 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Implemented WHOWAS command to the server. Added the functions:
5448 silc_server_command_whowas_parse,
5449 silc_server_command_whowas_send_reply,
5450 silc_server_command_whowas_from_client and
5451 silc_server_command_whowas_from_server
5453 * Added <Client ID> argument to the WHOWAS command reply. Updated
5454 the protocol specs accordingly.
5456 * Implemented WHOWAS command and command_reply to the client
5459 Implemented the WHOWAS printing on the user interface.
5461 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Added new argument to the WHOWAS command reply, the real name.
5464 It is an optional argument. Updated the protocol specs.
5466 * Added SilcIDCacheDestructor callback that is registered when
5467 the SilcIDCache is allocated. The callback is called when
5468 an cache entry in the ID Cache expires, or is purged from the
5469 cache. Added into lib/silccore/idcache.[ch].
5471 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5472 to destruct the client entries when the cache entry expires.
5473 Other ID Cache's in server and in the client library ignores
5476 * If the ID Cache entry's `expire' field is zero then the entry
5477 never expires. Added boolean `expire' argument to the
5478 silc_idcache_add function in the lib/silccore/idcache.[ch].
5479 If it is TRUE the default expiry value is used.
5481 * Added silc_server_free_client_data_timeout that is registered
5482 when client disconnects. By default for 5 minutes we preserve
5483 the client entry for history - for WHOWAS command.
5485 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Added support to the server to enforce that commands are not
5488 executed more than once in 2 seconds. If server receives
5489 commands from client more frequently, timeout is registered
5490 to process the commands. Affected file silcd/command.c.
5491 Added new function silc_server_command_process_timeout.
5493 * Changed NICK_NOTIFY handling in client library to check that
5494 if the client's nickname was changed, so there is no need to
5495 resolve anything from the server.
5497 * Removed error printing from the WHOIS and IDENTIFY commands.
5498 If error occurs then it is ignored silently in the client library.
5499 The application, however, may map the received error to
5500 human readable error string. The application currently maps
5501 the NO_SUCH_NICKNAME error to string.
5503 * Made the command status message public to the application. Moved
5504 them from lib/silcclient/command_reply.c to
5505 lib/silcclient/command_reply.h. The application can map the
5506 received command status to the string with the
5507 silc_client_command_status_message function.
5509 * Added check to the server to check that client's ID is same
5510 as the Source ID in the packet the client sent. They must
5513 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Added dist-bzip hook to the Makefile.am to make bzip2
5516 compressed distributions.
5518 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Server now enforces the maximum length for the nickname and
5521 the channel as protocol specification dictates. 128 bytes for
5522 nickname and 256 bytes for channel name.
5524 * Moved the WHOIS printing to the application. The client libary
5525 does not print out the WHOIS information anymore, the application
5526 must do it. Renamed silc_client_command_reply_whois_print to
5527 the silc_client_command_reply_whois_save.
5529 The client's idle time is also sent to the application now, and
5530 the idle is shown on screen.
5532 * Added silc_client_command_reply_identify_save to save the
5533 received IDENTIFY entries.
5535 * Do not check for channel private keys in message sending and
5536 reception if the channel does not have the PRIVKEY mode set.
5537 Affected file lib/silclient/client_channel.c.
5539 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5542 just surfaced after chaning the JOIN procedure.
5544 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Added silc_client_get_clients_by_list to get client entries
5547 from Client ID list, that is returned for example by JOIN
5548 and USERS command replies. The application should use this
5549 function for example when JOIN command reply is received to
5550 resolve the clients already on the channel (library does not
5551 do that anymore as USERS command reply is not used in the JOIN
5552 procedure anymore). Affected files lib/silcclient/silcapi.h and
5553 lib/silcclient/idlist.c.
5555 * JOIN command reply and USERS command reply returns now SilcBuffer
5556 pointers instead of unsigned char pointers when returning
5557 the client list and mode list.
5559 * Added <Client ID> argument to the JOIN command reply, mainly
5560 for the server to identify for which client the command was
5561 originally sent. Updated protocol specs accordingly.
5563 * Added SilcDlist private_key pointer to the SilcChannelEntry
5564 in the client to support the channel private keys. Affected
5565 file is lib/silcclient/idlist.h.
5567 * Added SilcChannelPrivateKey argument to the function
5568 silc_client_send_channel_message so that application can choose
5569 to use specific private ke if it wants to. If it is not provided,
5570 the normal channel key is used, unless private keys are set.
5571 In this case the first (key that was added first) is used
5572 as the encryption key.
5574 * Implemented the support for channel private key handling.
5575 Implemented the following functions:
5577 silc_client_add_channel_private_key,
5578 silc_client_del_channel_private_keys,
5579 silc_client_del_channel_private_key,
5580 silc_client_list_channel_private_keys and
5581 silc_client_free_channel_private_keys
5583 Affected file lib/silcclient/client_channel.c.
5585 * Added the support for the private keys in the channel message
5586 sending and encryption and in the message reception and
5587 decryption. Affected funtions are
5588 silc_client_send_channel_message and silc_client_channel_message.
5590 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added SKE's key verify callback to the client library's
5593 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5595 * Removed the statement that server (or router) must send USERS
5596 command reply when joining to the channel so that the client
5597 knows who are on the channel. Instead, the client list and
5598 client's mode list is now sent in the JOIN command reply to the
5599 client who joined channel. This is better solution.
5601 * Added function silc_server_get_users_on_channel and function
5602 silc_server_save_users_on_channel to the silcd/server.[ch].
5604 * Removed function silc_server_command_send_users from the
5607 * Do not show topic on the client library anymore. The topic is
5608 sent in the command reply notify to the application and the
5609 application must show the topic now.
5611 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Added client searching by nickname hash into the IDENTIFY and
5614 WHOIS commands in the server as they were clearly missing from
5615 them. Affected file is silcd/command.c.
5617 * Fixed a bug in private message receiving in the client library.
5618 The remote ID was freed and it wasn't supposed, now it is
5621 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Minor fix to the channel payload; allocate the data area, as it
5624 needs to be of specific length.
5626 * If the key agreement port is zero then the operating
5627 system will define the bound port. Affected files are
5628 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5630 * Added new function silc_channel_payload_decrypt into the file
5631 lib/silccore/silcchannel.[ch].
5633 * Moved the channel message etc, check from silc_packet_decrypt
5634 to applications. The library calls now a generic
5635 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5636 when the packet is either normal or special. This was done to
5637 allow more wide range of checking that was not allowed when
5638 the code was in library. Now applications can do virtually any
5639 checks to the packet and return to the library the decision how
5640 the packet should be processed. Affected files are
5641 lib/silccore/silcpacket.[ch].
5643 Added silc_server_packet_decrypt_check to the server and
5644 silc_client_packet_decrypt_check to the client library.
5646 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5647 to send with specified source and destination information.
5649 * Channel message delivery between routers was broken after the
5650 channel key distribution was fixed earlier. The channel key
5651 was used be to distributed to other routers as well which is not
5652 allowed by the protocol. Now this is fixed and channel keys
5653 really are cell specific and the channel message delivery between
5654 routers comply with the protocol specification.
5656 * Fixed various commands in server to check also the global list
5657 for the channel entry and not just the local list. The affected
5658 file silcd/command.c.
5660 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Added assert()s to buffer formatting and unformatting routines
5663 to assert (if --enable-debug) when error occurs. Affected
5664 file: lib/silcutil/silcbuffmt.c.
5666 * Changed to auto-reconnect to check whether the remote host is
5667 router and register the re-connect timeout if it is. It used
5668 to check that whether we are normal server, but router must do
5669 auto-reconnect with another router as well. Affected file
5672 * Removed the [<key len>] option from CMODE command as the cipher
5673 name decides the key length, nowadays. See the defined ciphers
5674 from the protocol specification.
5676 * Added [<hmac>] option to the CMODE command to define the HMAC
5677 for the channel. Added SILC_CMODE_HMAC channel mode.
5679 * Added [<hmac>] option for the JOIN command so that user can
5680 select which HMAC is used to compute the MACs of the channel
5683 * Added Hmac field to the Channel Message Payload. The integrity
5684 of plaintext channel messages are now protected by computing
5685 MAC of the message and attaching the MAC to the payload. The
5686 MAC is encrypted. Now, it is clear that this causes some
5687 overhead to the size of the packet but rationale for this is that
5688 now the receiver can verify whether the channel message decrypted
5689 correctly and also when private keys are set for the channel the
5690 receiver can decrypt the packet with several keys and check from
5691 the MAC which key decrypted the message correctly.
5693 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5694 lib/silccrypt/silccipher.[ch].
5696 * Added silc_hash_len to return the digest length into the
5697 lib/silcrypt/silchash.[ch].
5699 * Rewrote parts of Silc Channel Payload interface in the
5700 lib/silccore/silcchannel.[ch]. The encode function now also
5701 encrypts the packet and parse function decrypts it.
5703 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Fixed a minor formatting bug in the SKE's key material processing.
5706 It actually might have processed the keys wrong way resulting
5709 * Redefined the mandatory HMAC algorithms and added new algorithms.
5710 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5711 and hmac-md5 truncated to 96 bits. The mandatory is now
5712 hmac-sha1-96. Rest are optional (including the one that used
5713 to be mandatory). Rationale for this is that the truncated HMAC
5714 length is sufficient from security point of view and can actually
5715 make the attack against the HMAC harder. Also, the truncated
5716 HMAC causes less overhead to the packets. See the RFC2104 for
5719 * Added new [hmac] configuration section. The SKE used to use
5720 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5721 is of course wrong. The official names that must be proposed in
5722 the SKE are the ones defined in the protocol specification
5723 (hmac-sha1-96 for example). The user can configure any hmac
5724 using any hash function configured in the [hash] section. At
5725 least, the mandatory must be configured.
5727 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5729 * Added HMAC list to the SKE proposal list. It has now both
5730 hash algorithm list and HMAC list. This makes the protocol
5731 incompatible with previous versions. The SKE now seems to work
5732 the way it is supposed to work, for the first time actually.
5734 * Defined plain Hash algorithms to the protocol specification.
5737 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Implemented support for key agreement packets into the server.
5740 Added functions silc_server_key_agreement and
5741 silc_server_send_key_agreement. Other than these functions,
5742 server has nothing to do with this packet.
5744 * Added support for private message key packets into the server.
5745 Added functions silc_server_private_message_key and
5746 silc_server_send_private_message_key.
5750 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5751 called in the protocol's final callback instead in the END
5752 protocol state. This makes a little more sense and in the same
5753 time in client we can use the same protocol routines for normal
5754 key exchange and to key agreement packet handling as well.
5756 * Added to both client's and server's KE protocol context the
5757 SilcSKEKeyMaterial pointer to save the key material. We will
5758 bring the key material to the protocol's final callback by doing
5759 this. The final callback must free the key material.
5761 * Added SKE's packet_send callback into client's KE protocol
5762 context so that the caller can choose what packet sending function
5763 is used. This way we can use different packet sending when
5764 doing normal SKE when doing key agreement packet handling (in
5765 the key agreement packet handling we do not want to encrypt
5768 * Implemented the responder side of the key agreement routines
5769 in the client. The client can now bind to specified port and
5770 accept incoming key negotiation. The key material is passed
5771 to the application after the protocol is over.
5773 * Implemented the processing of incoming Key Agreement packet
5774 in the client. Added function silc_client_key_agreement to
5777 * Implemented the intiator side of the key agreement routines
5778 in the client. The client can now initiate key agreement with
5779 another remote client. The key material is passed to the
5780 application after the protocol is over.
5782 * Created client_keyagr.c to include all the key agreement
5785 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5786 SILC_TASK_CALLBACK except that it is not static.
5788 * Created client_notify.c and moved the Notify packet handling
5789 from the client.[ch] into that file.
5791 * Created client_prvmsg.c and moved all private message and
5792 private message key routines from the client.[ch] into that file.
5794 * Create client_channel.c and moved all channel message and
5795 channel private key routines from the client.[ch] into that file.
5797 * Changed silc_client_get_client_by_id_resolve to resolve with
5798 WHOIS command instead of IDENTIFY command, in the file
5799 lib/silclient/idlist.c.
5801 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Implemented the SKE's responder side to the Client library.
5805 * When FAILURE is received to the protocol do not trust it
5806 blindly. Register a timeout to wait whether the remote closes
5807 the connection as it should do it, only after that process the
5808 actual failure. This was changed to both client and server.
5810 * Added client_internal.h to include some of the structures
5811 there instead of client.h in lib/silcclient/.
5813 * Added function silc_task_unregister_by_callback to unregister
5814 timeouts by the callback function.
5816 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * Some "Incomplete WHOIS info" errors has been appearing on the
5819 log files. Took away the entry->userinfo check from WHOIS
5820 reply sending. The entry->userinfo is now " " if client did not
5821 provide one. I thought this was fixed earlier but something
5822 is wrong still. Let's see if the error still appears.
5824 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Fixed a minor bug in the login when the channel key is
5827 re-generated in the server. It used to generate the key in
5828 wrong order and thus caused problems in the channel traffic.
5830 * Fixed a minor bug in channel key distsribution after
5831 KICK command. The key was not sent to the router even though
5834 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Added silc_ske_process_key_material_data as generic routine
5837 to process any key material as the SILC protocol dictates. The
5838 function is used by the actual SKE library but can be used by
5839 applications as well. This relates to the private message keys
5840 and the channel private keys since they must be processed the
5841 same way the normal SILC session keys. The protocol dictates
5842 this. Affected files: lib/silcske/silcske.[ch].
5844 Added also silc_ske_free_key_material to free the
5845 SilcSKEKeyMaterial structure.
5847 * Defined silc_cipher_set_key function to set the key for
5848 cipher without using the object's method function. The affected
5849 files: lib/silccrypt/silccipher.[ch].
5851 * Implemented silc silc_client_add_private_message_key,
5852 silc_client_add_private_message_key_ske,
5853 silc_client_del_private_message_key,
5854 silc_client_list_private_message_keys and
5855 silc_client_free_private_message_keys functions in the
5858 Added functions silc_client_send_private_message_key to send
5859 the Private Message Key payload and silc_client_private_message_key
5860 to handle incoming Private Message Key payload.
5862 * Added Cipher field to the Private Message Key payload to set
5863 the cipher to be used. If ignored, the default cipher defined
5864 in the SILC protocol (aes-256-cbc) is used.
5866 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Removed lib/silcclient/ops.h file.
5870 Redefined parts of the SILC Client Library API. Created new
5871 file silcapi.h that deprecates the ops.h file and defines the
5872 published Client Library API. Defined also private message key
5873 API and channel private key API into the file.
5875 This is the file that the application must include from the
5876 SILC Client Library. Other files need not be included by
5877 the application anymore.
5879 * Added new key_agreement client operation callback and also
5880 defined the Key Agreement library API for the application.
5882 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5885 is used by clients to request key negotiation between another
5886 client in the SILC network. If the negotiation is started it
5887 is performed using the SKE protocol. The result of the
5888 negotiation, the secret key material, can be used for example
5889 as private message key.
5891 Implemented the Key Agreement payload into the files
5892 lib/silccore/silauth.[ch].
5894 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Redefined ciphers for the SILC protocol. Added some new ciphers
5897 and defined the key lengths for the algorithms. Changed the
5898 code accordingly. The default key length is now 256 bits.
5900 * Fixed SKE key distribution function silc_ske_process_key_material
5901 when the key length is more than 128 bits. The default key
5902 length in SILC is now 256 bits.
5904 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5905 to indicate unsupported algorithm.
5907 * Renamed rijndael.c to aes.c and all functions as well.
5909 * Fixed a long standing channel key setting bug in client library.
5910 Weird that it has never surfaced before.
5912 * Fixed bug in channel deletion. If the entire channel is removed
5913 then it must also delete the references of the channel entry
5914 from the client's channel list as the client's channel entry and
5915 the channel's client entry share same memory.
5917 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Implemented CONNECT and SHUTDOWN commands in the client.
5921 * Implemented CLOSE command to the client.
5923 * Added the function silc_idlist_find_server_by_name into the
5924 files silcd/idlist.[ch].
5926 Added the function silc_idlist_find_server_by_conn into the
5927 files silcd/idlist.[ch].
5929 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * DIE command was renamed to SHUTDOWN. Updated the both code
5934 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5935 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5937 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5940 * Added function silc_server_create_connection function to create
5941 connection to remote router. My server implementation actually
5942 does not allow router to connect to normal server (it expects
5943 that normal server always initiates the connection to the router)
5944 so the CONNECT command is only good for connecting to another
5947 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5950 or some other client was kicked from the channel.
5952 Implemented the handling of the notify type to both client
5955 Implemented silc_server_send_notify_kicked to send the KICKED
5956 notify. It is used to send it to the server's primary router.
5958 * Implemented the KICK command into server and client.
5960 * Added `query' argument to the silc_idlist_get_client function
5961 to indicate whether to query the client from server or not if
5964 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5965 to indicate that the client is not channel founder.
5969 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Removed the rng context from SilcPacketContext structure and
5972 changed that the packet routine uses the Global RNG API.
5974 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Added support for quit message that client can "leave" on the
5977 channel when it quits the SILC. It is ditributed inside the
5978 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5980 Added silc_server_free_client_data that will take the
5981 signoff message as argument.
5983 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5985 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5987 * Updated parts of the protocol specification to keep it up
5990 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5993 payloads in one packet.
5995 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5996 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5997 use now the new List flag.
5999 * Also deprecated the following packet types: REPLACE_ID,
6000 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6002 * Added list support for Notify packet in server.
6004 * Added silc_server_send_notify_channel_change to send the
6005 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6006 the silc_server_send_replace_id.
6008 * Added silc_server_send_notify_nick_change to send the
6009 NICK_CHANGE notify type. Deprecates the function
6010 silc_server_send_replace_id.
6012 * Added silc_server_send_notify_join to send the JOIN notify type.
6013 Deprecates the function silc_server_send_new_channel_user.
6015 * Added silc_server_send_notify_leave to send LEAVE notify type.
6016 Deprecates the function silc_server_send_remove_channel_user.
6018 * Added silc_server_send_notify_cmode and
6019 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6020 types. Deprecates the silc_server_send_set_mode function.
6022 * Added SERVER_SIGNOFF notify type to indicate that server has
6023 quit. This means that all clients on the channel from that
6024 server will drop. This can be also used when netsplit happens.
6026 Deprecated REMOVE_ID packet type since it is not needed anymore
6029 Added silc_server_send_notify_server_signoff to send the
6030 SERVER_SIGNOFF notify type. Deprecates the function
6031 silc_server_send_remove_id.
6033 Added also silc_server_send_notify_signoff to send the
6034 SIGNOFF notify type.
6036 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6037 SILC protocol from this day on. Changed the protocol
6038 specification as well.
6040 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6041 notify type. It is used between routers to notify about
6042 topic changes on a channel.
6044 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6047 * Partly updated the protocol specification to comply with the
6048 changes now made. It is still though a bit outdated.
6050 * The JOIN notify type now takes one extra argument <Channel ID>.
6051 The packet used to be destined to the channel but now the
6052 JOIN type may be sent as list thus it is impossible to
6053 destine it to any specific channel. By adding this argument
6054 it is again possible.
6056 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added CREDITS file. The CHANGES and CREDITS file will appear
6059 in the distribution as well.
6061 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6064 types in the server's silcd/packet_receive.c.
6066 * Implemented CMODE and CUMODE to work in router environment.
6068 * Fixed minor encoding and decoding buglet from the
6069 lib/silccore/silcmode.c.
6071 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6074 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6076 * Changed all SilcConfigServer* and silc_config_server* to
6077 SilcServerConfig* and silc_server_config*, respectively.
6080 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Associated the ID (client or server ID) to the Authentication
6083 Payload to avoid any possibility of forging. Updated the
6084 protocol specification and the code accordingly.
6086 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * The RSA key length is now save to the RsaKey context in the
6089 key generation process in lib/silccrypt/rsa.c. The key length
6090 is now used to figure out the maximum size of the block allowed
6091 to be encrypted/signed.
6093 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6094 is equivalent to the silc_mp_mp2bin but does not allocate any
6097 * Changed silc_mp_mp2bin API to take length argument. If it is
6098 non-zero then the buffer is allocated that large. If zero, then
6099 the size is approximated using silc_mp_sizeinbase, which however
6102 * Created Global RNG API which is global RNG that application can
6103 initialize. After initializing, any routine anywhere in the
6104 code (including library) can use RNG without allocating a new
6105 RNG object. This was done to allow this sort of use of the
6106 RNG in code that has no chance to allocate RNG object. All
6107 applications currently allocate this and many routines in the
6108 library use this. Affected file lib/silccrypt/silcrng.[ch].
6110 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6111 it to use the Global RNG API.
6113 * Defined Authentication Payload into protocol specification that
6114 is used during SILC session to authenticate entities. It is
6115 used for example by client to authenticate itself to the server
6116 to obtain server operator privileges.
6118 Implemented this payload into the lib/silccore/silcauth.[ch].
6119 Implemented also routines for public key based authentication
6120 as the new protocol specification dictates.
6122 Moved definitions of different authentication methods from
6123 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6125 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6126 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6127 silc_pkcs_verify_with_hash functions into the file
6128 lib/silccrypt/silcpkcs.[ch].
6130 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * The client entry's userinfo pointer must be always valid.
6133 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6134 will fail since it requires the userinfo. Now, the userinfo
6135 is allocated as "" if actual userinfo does not exist. Actually,
6136 it must exist and it is totally Ok to drop client connections
6137 that does not announce the userinfo. However, we will make
6138 this workaround for now.
6140 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6141 to return the remote port by socket.
6143 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6146 SILC_SERVER_PENDING_EXEC and added an new macro
6147 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6148 data or when error occurs while processing the pending command.
6150 Added new argument `destructor' into silc_server_command_pending
6151 and to the SilcServerCommandPending object. This destructor is
6152 now called after calling the pending callback or if error occurs
6153 immediately. If error occurs the actual pending callback won't
6154 be called at all - only the destructor. The destructor may be
6155 NULL if destructor is not needed.
6157 All this applies for client library code as well. Similar
6158 changes were made there as well for the pending commands.
6160 In the client, the application must now allocate the
6161 SilcClientCommandContext with the silc_client_command_alloc
6164 * Added reference counter to the SilcServerCommandContext. Added
6165 function silc_server_command_alloc and silc_server_command_dup
6168 Same type of functions added to the client library for the same
6171 * Removed the cmd_ident from IDListData away since it is now
6172 global for all connections. It is the command identifier used
6173 in command sending and with pending commands. The affected file
6176 * Added reference counter to the SilcSocketConnection objecet to
6177 indicate the usage count of the object. The object won't be
6178 freed untill the reference counter hits zero. Currently only
6179 server uses this, and client ignores it. The client must be
6180 set to use this too later. The affected files are
6181 lib/silccore/silcsockconn.[ch]. Added also the function
6182 silc_socket_dup to increase the reference counter.
6184 This was mainly added because it is possible that the socket
6185 is removed underneath of pending command or other async
6186 operation. Now it won't be free'd and proper DISCONNECTING
6187 flags, etc. can be set to avoid sending data to connection that
6188 is not valid anymore.
6190 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6191 the connection. After that it sets SILC_SET_DISCONNECTED.
6192 It is, however, possible that the socket data is not still freed.
6193 The silc_server_packet_process now checks that data is not
6194 read or written to connection that is DISCONNECTED. The socket
6195 get's freed when the reference counter hits zero.
6197 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Changed the client operation API: channel_message operation's
6200 `sender' is now the client entry of the sender, not the nickname
6201 and the `channel' is the channel entry, not the channel name.
6203 In the private_message operation the `sender' is now also the
6204 client entry of the sender not the nickname.
6206 Affected file is lib/silcclient/ops.h and all applications
6207 using the client operations.
6209 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Moved the calling of ops->connect() from connect_to_server_final
6212 into receive_new_id functin since that is the point when the
6213 client is actually allowed to send traffic to network. The
6214 affected file is lib/silcclient/client.c.
6216 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6219 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6220 (if needs broadcasting) instead of broadcasting the packets one
6221 by one which would make a burst in the network traffic.
6223 * Added `broadcast' argument to the functions in silcd/server.[ch]
6224 silc_server_create_new_channel[_with_id] to indicate whether
6225 to send New Channel packet to primary router.
6227 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * Added new function into the silcd/server.[ch] files:
6230 silc_server_create_new_channel_with_id to create new channel with
6231 already existing Channel ID.
6233 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6234 lib/silccore/silcpacket.h. This packet is used t send list of
6235 Set Mode payloads inside one packet. Server uses this to set
6236 the modes for the channels and clients on those channels, that it
6237 announced to the router when it connected to it. The protocol
6238 specification has been updated accordingly.
6240 * The silc_server_new_channel did not handle the packet coming
6241 from normal server as it normally does not send that. However,
6242 when it announces its channels it does send it. Implemented
6243 the support for that.
6245 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6246 into the file lib/silccore/id.h.
6248 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Fixed memory leaks in the functions silc_idlist_del_client,
6251 silc_idlist_del_channel and silc_idlist_del_server in the file
6252 silcd/idlist.c. All of those leaked like a sieve.
6254 * Fixed some small memory leaks in the client's function
6255 silc_client_notify_by_server.
6257 * Added functions into silcd/server.c: silc_server_announce_clients,
6258 silc_server_announce_channels and silc_server_announce_server.
6259 These functions are used by normal and router server to announce
6260 to its primary router about clients, channels and servers (when
6261 router) that we own. This is done after we've connected to the
6264 These functions effectively implements the following packet types:
6265 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6266 and SILC_PACKET_NEW_ID_LIST.
6268 * Added new functions into the silcd/packet_receive.[ch]:
6269 silc_server_new_id_list, silc_server_new_channel_list and
6270 silc_server_new_channel_user_list to handle the incoming
6271 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6273 * Added support of changing Channel ID in the function
6274 silc_server_replace_id. If the server that announces a channel
6275 to the router already exists in the router (with same name but
6276 with different Channel ID), router is responsible to send
6277 Replace ID packet to the server and force the server to change
6278 the Channel ID to the one router has.
6280 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6281 client that the Channel ID has been changed by the router. The
6282 normal server sends this to the client. Client must start using
6283 the new Channel ID as the channel's ID.
6285 Implemented handling of this new type into lib/silcclient/client.c
6286 into the function silc_client_notify_by_server.
6288 * Added new function silc_idlist_replace_channel_id into the files
6289 silcd/idlist.[ch] to replace the Channel ID.
6291 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Call silc_server_command_identify_check always when processing
6294 the IDENTIFY command in silcd/command.c
6296 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6299 send keepalive packets. The packet can be sent by clients,
6300 servers and routers.
6302 Added function silc_socket_set_heartbeat into the file
6303 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6304 If not set, the heartbeat is not performed. The actual
6305 heartbeat is implemented in the low level socket connection
6306 library. However, application is responsible of actually
6309 Added silc_server_send_heartbeat to send the actual heartbeat
6310 packet into silcd/packet_send.[ch]. Server now performs
6311 keepalive with all connections.
6313 * Added silc_task_get_first function into lib/silcutil/silctask.c
6314 to return the timeout task with shortest timeout. There was a bug
6315 in task unregistration that caused problems. TODO has been
6316 updated to include that task system must be rewritten.
6318 * The client library will now resolve the client information when
6319 receiving JOIN notify from server for client that we know but
6320 have incomplete information.
6322 * Rewrote parts of silc_server_remove_from_channels and
6323 silc_server_remove_from_one_channel as they did not remove the
6324 channel in some circumstances even though they should've.
6326 * Encryption problem encountered in server:
6328 The LEAVE command used to send the Channel Key packet to the
6329 router immediately after generating it. However, the code
6330 had earlier sent Remove Channel user packet but not immediately,
6331 ie. it was put to queue. The order of packets in the router
6332 was that Channel Key packet was first and Remove Channel User
6333 packet was second, even though they were encrypted in the
6334 reverse order. For this reason, MAC check failed. Now, this
6335 is fixed by not sending the Channel Key packet immediately but
6336 putting it to queue. However, this is more fundamental problem:
6337 packets that are in queue should actually not be encrypted
6338 because packets that are sent immediately gets encrypted
6339 actually with wrong IV (and thus MAC check fails). So, packets
6340 that are in queue should be encrypted when they are sent to
6341 the wire and not when they put to the queue.
6343 However, the problem is that the current system has not been
6344 designed to work that way. Instead, the packet is encrypted
6345 as soon as possible and left to the queue. The queue is then
6346 just purged into wire. There won't be any fixes for this
6347 any time soon. So, the current semantic for packet sending
6350 o If you send packet to remote host and do not force the send
6351 (the packet will be in queue) then all subsequent packets to the
6352 same remote host must also be put to the queue. Only after the
6353 queue has been purged is it safe again to force the packet
6356 o If you send all packets immediately then it safe to send
6357 any of subsequent packets through the queue, however, after
6358 the first packet is put to queue then any subsequent packets
6359 must also be put to the queue.
6361 Follow these rules and everything works fine.
6363 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Added new function silc_server_remove_clients_by_server to
6366 remove all client entries from ID list when the server connection
6367 is lost. In this case it is also important to invalidate all
6368 client entires as they hold the invalid server entry. This
6369 fixes fatal bug when server has lost connection and will reconnect
6372 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Made some sanity checks to silc_server_daemonise like to check
6375 whether the requested user and group actually exists.
6377 * Added sanity check to SKE's silc_ske_responder_finish to check
6378 that the public and private key actually is valid.
6380 * Invalidate the client's nickname when receiving Replace ID
6381 packet and the Client ID is being replaced. This means that the
6382 server will query the nickname if someone needs it (client)
6385 * Sort the ID Cache in client library when the ID Cache data
6386 has changed (needs sorting).
6388 * Do not allow for SILC client to create several connections to
6389 several servers. The client does not support windows right now
6390 and generating multiple connections causes weird behaviour.
6392 Irssi-silc client does support windows and can handle several
6393 connections without problems, see: www.irssi.org and SILC plugin.
6395 * Fixed some places where client was added to the IDList. The
6396 rule of thumb is following (in order to get everything right):
6397 If the client is directly connected local client then the
6398 `connection' argument must be set and `router' argument must be
6399 NULL to silc_idlist_add_client function. If the client is not
6400 directly connected client then the `router' argument must
6401 bet set and the `connection' argument must be NULL to the
6402 silc_idlist_add_client function.
6404 * The funtion silc_server_packet_send_local_channel actually did
6405 not check whether the client was locally connected or not. It
6406 does that now. Fixed a bug related to LEAVE command.
6408 * Fixed Remove Channel User payload parsing bug in server's
6409 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6411 * The server's silc_server_save_channel_key now checks also the
6412 global ID list for the channel as it might not be in the local
6413 list. Fixed a bug related to LEAVE command.
6415 * Is this the end of the [<unknown>] buglet that has been lurking
6416 around for a long time? A little for loop fix in server's
6417 silc_server_command_whois_parse that is used by both IDENTIFY
6418 and WHOIS command. At least, this was a clear bug and a cause
6419 of one type of [<unknown>] buglet.
6421 * WHOIS and IDENTIFY commands call the function
6422 silc_server_command_[whois/identify]_check function even if
6423 we are not router server.
6425 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6427 * Added --with-gmp configuration option. If set the GMP
6428 is always compiled in the SILC source tree. If not set then
6429 it is checked whether the system has the GMP3 installed. If
6430 it has then the GMP won't be compiled (the system's headers
6431 and library is used), if it doesn't have it then the GMP is
6432 compiled in the SILC source tree.
6434 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Changed RSA private exponent generation to what PKCS #1
6437 suggests. We try to find the smallest possible d by doing
6438 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6439 not security fix but optimization.
6441 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Added new config entry [Identity] to fork the server and run
6444 it as specific user and group. A patch from Bostik.
6446 * Imported Dotconf configuration library into lib/dotconf.
6447 This will be used to create the SILC configuration files later.
6448 It will appear in the distsribution after this commit.
6450 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * A big code auditing weekend happening. Auditing code for
6453 obvious mistakes, bugs and errors. Also, removing any code
6456 Removed files for being obsolete:
6458 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6459 inline in the file lib/silcutil/silcbuffer.h)
6461 o lib/silcutil/silcbufutil.c (the header has inline versions)
6463 Changed code to fix possible error conditions:
6465 o The buffer formatting routines now check that the destination
6466 buffer really has enough space to add the data. This applies for
6467 both buffer formatting and unformatting
6468 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6469 unformatting was changed to accomodate following rules:
6470 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6471 sent to the function while XXX_*STRING will not allocate or copy
6472 the data into the buffer. Instead it sets the pointer from the
6473 buffer into the pointer sent as argument (XXX_*STRING used to
6474 require that the pointer must be allocated already). This change
6475 makes this whole thing a bit more consistent and more optimized
6476 (note that the data returned in the unformatting with XXX_*STRING
6477 must not be freed now). The routines return now -1 on error.
6479 o Tried to find all code that use buffer_format and buffer_unformat
6480 and added return value checking to prevent formatting and
6481 especially unformatting errors and possible subsequent fatal
6484 o Changed ske->x and ske->KEY to mallocated pointers in
6485 lib/silcske/silcske.h. Fixed possible data and memory leak.
6487 o Added return value checking to all *_parse* functions. Fixed
6488 many memory leaks as well.
6490 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6491 so that buffer overflows would not happen. All code now also
6492 checks the return value as it can fail.
6494 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * Added reconnection support to server if the normal server looses
6497 its connection to the router (for example if router is rebooted).
6498 The server performs normal reconnection strategy implemented
6499 to the server. Affected file silcd/server.c.
6501 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Added new packet type SILC_PACKET_SET_MODE that is used to
6504 distribute the information about changed modes (for clients,
6505 channels and clients channel modes) to all routers in the
6506 network. Updated the protocol specification accordingly.
6508 Added functions into silcd/packet_send.c and
6509 silcd/packet_receive.c: silc_server_send_set_mode,
6510 silc_server_set_mode.
6512 Added new files silcmode.[ch] into lib/silccore that implements
6513 the encoding and decoding of Set Mode Payload. Added new type
6514 SilcSetModePayload. Moved the definitions of different modes
6515 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6517 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Oops, a little mistake in server's connection authentication
6520 protocol. The protocol is not ended with FAILURE but with
6521 SUCCESS if the authentication is Ok. :) Affected file is
6524 * Implemented NICK_CHANGE notify handling in server in the file
6525 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6526 the local clients on the channel. After the changing nickname
6527 in router environment snhould work and the [<unknown>] nickname
6528 should appear no more.
6530 The silc_server_replace_id function that receives the Replace ID
6531 payload now sends the NICK_CHANGE notify type also in the file
6532 silcd/packet_receive.c
6534 * Changed WHOIS and IDENTIFY command to support the maximum amount
6535 of arguments defined in protocol specs (3328 arguments). This
6536 fixed a bug that caused problems when there were more than three
6539 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Added extra parameter, command identifier, to the
6542 silc_client_send_command so that explicit command identifier
6545 Changed that ID list routines uses specific command identifier
6546 when sending WHOIS/IDENTIFY requests to the server so that they
6547 can be identified when the reply comes back.
6549 Affected files lib/silcclient/command.[ch],
6550 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6552 * Added `sender' argument to silc_server_packet_send_to_channel
6553 to indicaet the sender who originally sent the packet to us
6554 that we are now re-sending. Ignored if NULL. Affected file
6555 silcd/packet_send.[ch].
6557 * Added some server statistics support in silcd/server_internal.h
6558 SilcServerStatistics structure and around the server code. Also
6559 send some nice statistics information when client is connecting
6562 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * Fixed channel ID decoding in server's JOIN command reply in
6565 silcd/command_reply.c
6567 * Fixed braodcasting of replace ID payload to not to send it if
6568 we are standalone server in silcd/packet_receive.c.
6570 * Fixed all channel message sending routines to not to send
6571 packets to clients that has router set, since they are routed
6572 separately in the same function earlier. Affects file
6573 silcd/packet_send.c and all channel packet sending functions.
6575 * In USERS reply, res_argv[i] are not allocated, the table
6576 is allocated. Thus changed that free the table, not its
6579 * In server's whois_check and identify_check if the client is
6580 locally connected do not send any WHOIS commands - they are not
6583 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Fixed some minor bugs in client when sending WHOIS command. The
6586 arguments was in wrong order.
6588 * Removed statis function add_to_channel from server in
6589 silcd/command.c that was previously used with the joining but
6592 * Tested USERS command in router environment successfully with two
6593 routers, two servers and two clients.
6595 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Reorganized the USERS command and command reply in client library
6598 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6599 When the command is given by user we register a pending command
6600 callback that will reprocess the command after the reply has been
6601 received from the server. When reprocessing the packet we then
6602 display the information. Thus, the USERS information is displayed
6603 now in the command callback instead of in the command reply
6604 callback. The processing of the command is same as previously
6605 when server has sent the command reply in the JOINing process.
6607 * Added to USERS command in silcd/command_reply.c to join the client,
6608 we didn't use to know about, to the channel after we've created
6609 a client entry for it. Also, for clienet we did know already still
6610 check whether it is on the channel or not and add it if not.
6612 * Removed silc_server_command_join_notify as the function and its
6615 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Changed the client's pending command handling to the same as the
6618 server's pending command handling. It is also now possible to
6619 execute command reply functions from other command reply
6620 function as the function callbacks for commands and command
6621 replies are one and same. The pending commands are not static
6622 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6623 in client connection context. Thus, pending commands are server
6624 connection specific as it is convenient.
6626 Changed the function silc_client_command_pending and
6627 silc_client_command_pending_del and added new function
6628 silc_client_command_pending_check. Removed the
6629 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6632 * Added cmd_ident, current command identifier, to the client
6633 connection context in lib/silcclient/client.h to keep track on
6634 command identifiers used in command sending. Client's command reply
6635 function handling now supports the mandatory command identifiers.
6637 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6638 funtions in client to fully support pending command callbacks.
6640 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6641 as one of the arguments to the application in the command reply
6644 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6645 before first releasing SILC but came back. Now it is removed again
6646 and should come back nomore. The FORWARDED flag was used only
6647 by the JOINing procedure by forwarding the command packet to router.
6648 Now, the JOINing procedure has been changed to more generic (due
6649 to various router environment issues) and FORWARDED is not needed
6650 anymore for anything. The protocol specification is yet to be
6653 Now, removed silc_server_packet_forward from server and the flag
6654 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6656 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Renamed NAMES command to USERS command. The NAMES was named that
6659 due to historical reasons. Now it is renamed. Also, rewrote
6660 parts of the USERS command. The nickname list is not sent anymore
6661 by the server. Only Client ID and mode lists are sent in the USERS
6662 command. Changed this also to the protocol specification.
6664 The client now resolves the names and stuff after it receives
6665 the USERS list from the server when joining to the channel.
6667 * WHOIS and IDENTIFY commands has been changed to support multiple
6668 Client ID's per command. One can now search for multiple users
6669 in the network by sending only one WHOIS or IDENTIFY command.
6670 Changed the code and the protocol specifications.
6672 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6673 uses silc_server_command_whois_parse to parse the request. */
6675 * If normal server, do not parse the WHOIS and IDENTIFY requests
6676 before sending it to the router. Saves some time.
6678 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed JOIN command on client library. Wrong number of arguments
6681 used to crash the client.
6683 * Added silc_server_channel_has_global function to check whether
6684 channel has global users or not.
6686 * Added silc_server_channel_has_local function to check whether channel
6687 has locally connected clients on the channel.
6689 * The silc_server_remove_from_one_channel now checks whether the
6690 channel has global users or not after given client was removed from
6691 the channel. It also checks whether the channel has local clients
6692 on the channel anymore. If it does not have then the channel entry
6693 is removed as it is not needed anymore.
6695 * The silc_server_notify now checks on JOIN notify whether the joining
6696 client is one of locally connected or global. If it is global then
6697 the channel has now global users on the channel and that is marked
6698 to the channel entry. Also, it now saves the global client to
6699 global list who is joining and JOINs it to the channel. This is
6700 for normal server, that is.
6702 Changed silc_server_send_notify_on_channel,
6703 silc_server_packet_relay_to_channel and
6704 silc_server_packet_send_to_channel check if we are normal server
6705 and client has router set (ie. global client) do not send the
6706 message to that client, as it is already routed to our router.
6708 * Implemented LEAVE notify type handling in silc_server_notify
6711 * Tested LEAVE command in router environment successfully. Tested
6712 with two routers, two servers and two clients.
6716 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6718 * Implemented SIGNOFF notify type handling in silc_server_notify
6721 * silc_server_remove_id now removes the client entry from all channels
6722 it has joined and thusly sends SIGNOFF notify type.
6724 * Rewrote the NAMES list generation in server by removing two excess
6725 loops. The lists are created now inside one loop.
6727 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6729 * silc_server_remove_channel_user checks now also global list
6730 for channel and client.
6732 * silc_server_new_channel_user checks now both local and global
6733 list for channel and client. Fixed a bug in client id decoding.
6734 Used to decode wrong buffer.
6736 * silc_server_channel_message checks now both local and global
6737 list for channel entry.
6739 * Tested channel joining (hence JOIN) in router environment
6740 successfully. Tested with two routers, two servers and two
6743 * Tested channel message sending in router environment successfully.
6745 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Added silc_server_save_channel_key into server.[ch] to save the
6748 received channel key in Channel Key payload processing. It is
6749 also used in JOIN command reply handling.
6751 Equivalent function silc_client_save_channel_key added into
6752 client.[ch] into client library.
6754 * Changed JOIN command reply to send information whether the channel
6755 was created or not (is existing already) and the channel key
6756 payload. Changed protocol specs accordingly.
6758 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6759 the request was sent by ID and not by nickname. Crashed on
6762 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6765 now correctly save the received data.
6767 * silc_server_free_sock_user_data now notifies routers in the
6768 network about entities leaving the network.
6770 At the same time implemented functions silc_server_remove_id
6771 and silc_server_send_remove_id to receive and send REMOVE_ID
6772 packets. The packet is used to notify routers in the network
6773 about leaving entities. The ID removed will become invalid in
6776 * Added function silc_idlist_del_server into server. Removes and
6777 free's server entry from ID list.
6779 * silc_server_private_message function now checks, if we are router,
6780 that the destination ID really is valid ID, naturally.
6782 * In router when NEW_ID packet is received (for new client) the
6783 hash of the Client ID is saved in the ID Cache but the
6784 client->nickname is set to NULL, instead of putting the hash
6787 IDENTIFY command now also checks that client->nickname must be
6788 valid. If it is not if will request the data from the server who
6789 owns the client. Added new function
6790 silc_server_command_identify_check.
6792 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6793 to set the command to already allocated Command Payload.
6795 * Tested private message sending in router environment with two
6796 routers, two servers and two clients. Fixed minor bugs and now
6799 * Fixed segfault from client's NAMES command. Used to crash if
6802 * Forwarded packets must not be routed even if it is not destined
6803 to the receiver. Changed server code comply with this.
6805 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Added `require_reverse_mapping' boolean value to ServerParams
6808 structure. If TRUE (not default) the server will require that
6809 the connecting host has fully qualified domain name.
6811 If the reverse mapping is not required and hostname could not be
6812 found the IP address is used as hostname.
6814 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6816 * Implemented version string checking to both client and server.
6817 The check is incomplete currently due to the abnormal version
6818 strings used in development version of SILC.
6820 * Changed all command functions in server to use the new
6823 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Changed char *data to unsigned char *data in ID Cache system to
6826 support binary data as ID Cache data. Changed code to support
6827 binary data in lib/silccore/idcache.c.
6829 * Renamed silc_server_packet_relay_command_reply to
6830 silc_server_command_reply as it is normal packet receiving
6831 function. Rewrote the function to accept command replys for
6832 servers and not only for clients.
6834 * Mark remote router always as registered server if we are connecting
6835 to it. Otherwise, commands sent by the router to us are ignored.
6837 * All ID List find routines now returns the ID Cache Entry pointer
6838 as well if requested.
6840 * WHOIS command works now in router environment, tested with two
6841 routers, two servers and two clients.
6843 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6844 in router environment (as it is almost equivalent to WHOIS) but
6845 hasn't been tested thoroughly. Added new functions:
6847 silc_server_command_identify_parse
6848 silc_server_command_identify_send_reply
6849 silc_server_command_identify_from_client
6850 silc_server_command_identify_from_server
6852 * Disabled route cache adding because adding two different ID's with
6853 same IP replaces the old cache entry thus giving wrong route.
6854 The entry->router->connection is always the fastest route anyway
6855 so route cache may not be needed. Of course, new routes maybe
6856 established after receiving the ID when the entry->router->connection
6857 might not be anymore the most optimal.
6859 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Add route cache for received ID for fast routing.
6863 * Added silc_server_packet_route to route received packet on router
6864 that is not destined to us.
6866 * Renamed silc_server_get_route to silc_server_route_get.
6868 * Added id_string and id_string_len fields into SilcServer to
6869 include encoded ServerID for fast comparing without excess
6870 encoding of the ID's.
6872 * Cleaned up WHOIS command on server side. Added following static
6875 silc_server_command_whois_parse
6876 silc_server_command_whois_check
6877 silc_server_command_whois_send_reply
6878 silc_server_command_whois_from_client
6879 silc_server_command_whois_from_server
6881 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6882 arguments in command replies. All command functions should be
6883 updated to use this macro.
6885 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Minor typo fixes on command reply handling on server.
6889 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Added silc_server_command_add_to_channel internal routine to add
6892 the client to the channel after router has created the channel and
6893 sent command reply to the server.
6895 * Added generic silc_server_send_command to send any command from
6898 * Use static buffer with ID rendering instead of duplicating data.
6900 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Fixed a channel user mode bug when joining to a channel server gave
6903 everybody channel founder rights, oops.
6905 * We mark ourselves as the router of the incoming server connection
6906 if we are router ourselves. This way we can check in some packet
6907 sending functions whether it is locally connected server. For
6908 incoming router connections we put NULL.
6910 * For router sending packets locally means now always sending the
6911 packet cell wide; to local clients and local servers. For normal
6912 server sending packet locally means sending it to only local
6915 * Fixed the JOIN command to really work in router environment. If the
6916 channel is created it is always created by the router. Router is
6917 also responsible of making the initial joining to the channel,
6918 sending JOIN notify to the sending server and distributing
6919 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6920 does not exist server doesn't do anything else but forward the
6921 command to the router which performs everything.
6923 * Added silc_server_send_channel_key function to send the Channel Key
6926 * Added silc_server_create_channel_key to create new channel key. The
6927 channel key is now re-generated everytime someone joins or leaves
6928 a channel, as protocol dictates. Note: channel->key_len is the
6931 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6934 packet_receive.[ch] to separate packet sending and receiving
6935 routines. The server.[ch] now includes everything else including
6936 actual packet processing (writing and reading data) and other
6939 Renamed silc_server_private_message_send_internal to
6940 silc_server_send_private_message. The routine is still though
6941 used only to relay private messages as server does not send
6942 private messages itself.
6944 Renamed silc_server_new_channel to silc_server_create_new_channel
6945 and added new function sicl_server_new_channel that handles the
6946 incoming New Channel packet. Added also new sending function
6947 silc_server_send_new_channel to send New Channel Payload.
6949 * Added new function silc_server_notify to process incoming notify
6950 packet to the server/router. Server may then relay the notify
6951 to clients if needed.
6953 * Added new function silc_server_new_channel_user to process incoming
6954 New Channel User packet. Router will redistribute the packet and
6955 send JOIN notify to its local clients and locally connected servers
6956 if needed. Normal server will send JOIN notify to its local client
6957 on same channel when received this packet. Added also corresponding
6958 sending function silc_server_send_new_channel_user to sent the
6961 * Added boolean route argument to send_notif_to_channel and
6962 packet_send_to_channel functions to attempt to route the packet
6963 if it is TRUE and send only locally if it is FALSE.
6965 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * silc_server_replace_id now broadcasts the received replace ID
6968 packet if it is not broadcast packet already. The router must
6969 broadcast to inform other routers about changed ID.
6971 * Added backpointer to server's router into SilcServer context in
6972 silcd/server_internal.h.
6974 * Fixed silc_server_packet_broadcast to send correct broadcast
6977 * The channel key is now distributed to the local client as soon
6978 as it is received from the router (in router environment) so that
6979 no other packet may be sent for the channel until client has
6982 * silc_server_remove_channel_user now broadcasts the received
6983 Remove Channel User packet if it is not broadcast packet already.
6984 The router must broadcast to inform other routers about removed
6987 * Added users field into SilcPacketContext that is a reference count
6988 of the context. One can increase the reference count by calling
6989 silc_packet_context_dup which is now changed to just increase the
6990 reference count instead of duplicating the data. The reference
6991 count is decresed by calling silc_packet_context_free that will
6992 free the data after the reference count hits zero.
6994 For now on the packet context and everything allocated into it
6995 (including the raw packet from network) must be freed by calling
6996 the new silc_packet_context_free function. Added also new function
6997 silc_packet_context_alloc that must be used now to allocate the
6998 context. This also means that if a routine is asynchronous from
6999 silc_[client/server]_packet_parse_type the packet context must
7000 be duplicated by calling silc_packet_context_dup. Otherwise it
7001 gets free'd after silc_[client/server]_packet_parse_type returns.
7002 Also, one must remember that if packet is duplicated then its
7003 reference count must be decresed by calling the free function as
7004 many times as it was duplicated.
7006 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7007 from both client and server.
7009 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Made joining to a channel working in router environment.
7013 * Cleaned up JOIN command on server side and create function
7014 silc_server_command_join_channel internal routine to make the
7017 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7019 * Changed silc_command_pending list to SilcDList. Also, added
7020 `ident' field to SilcServerCommandPending structure to identify
7021 the reply and to call correct callback.
7023 Added silc_server_command_pending_check function to replace the
7024 corresnponding macro. The silc_command_pending list is not
7027 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7028 to set identifier to previously allocated Command Payload. It
7029 is used to set identifier for command when resending Command
7032 * Added silc_command_payload_encode_payload to encode Command
7033 Payload buffer from SilcCommandPayload structure.
7035 * Added silc_argument_payload_encode_payload to encode Argument
7036 payload buffer from SilcArgumentPayload structure.
7038 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Changed WHOIS command to support router connection on server side.
7041 The whois request is always sent to router unless the server is
7042 standalone server. After server has received the reply from the
7043 router will it send the reply to the client.
7045 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7046 broadcast received broadcast packet. The function is used only
7047 by router. The broadcast packet is always sent to the router's
7050 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7051 render given ID to printable string, for log files for example.
7053 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Made basic router to router connections working. At least they
7056 can now connect to each other but nothing really works the way
7057 they are supposed - yet.
7059 * Added new initiator token to RouterConnection configuration
7060 file in silcd/serverconfig.[ch]. It is used to tell whether we
7061 are the initiator to the remote router or whether we'll expect
7062 the other end to connect.
7064 * Moved registering of listener task to silc_server_init, hence
7065 the server starts listenning as soon as it is run, even if it
7066 does not have connections to other routers. Let's see how well
7069 * Changed default connection retry timeouts for more suitable in
7072 * Removed cipher and such arguments from silc_idlist_add_client
7073 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7074 Added new function silc_idlist_add_data to add the keys and stuff
7077 * Added SilcIDListData structure and added it to SilcClientEntry
7078 and SilcServerEntry as their first field in the structure. This
7079 way we can explicitly cast the ID entries to the SilcIDListData
7080 structure and get common data for the entries. In past, we had
7081 to first check what type of connection it is and then cast it to
7082 correct ID entry type. Now, we can directly cast the opaque
7083 pointer to the SilcIDListData (no matter what ID entry it actually
7084 is) and get the data needed.
7086 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7089 in some circumstances even if threre were timeout tasks, though not
7090 IO tasks, but tasks anyway. Now fixed.
7092 * Defined SilcServerConnection structure to hold connection specific
7093 stuff about directly connected servers and routers. The definition
7094 is currently in silcd/server_internal.h. I thought about having
7095 a bit more important role fro this struct but for now it is used
7096 only when connecting to other server (or router actually).
7098 * Added connecting retry support in server when connecting to
7099 router(s). The retry feature implement exponential backoff
7100 algorithm. Also, added SilcServerParams structure to hold default
7101 parameters for server. For now, it include these retry settings
7102 and are hard coded. After server is moded to be as Silc Server
7103 Library this structure will be more important.
7105 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * Changed client librarys channel->clients table to SilcList and
7108 changed code accordingly.
7110 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Changed client's channel table to SilcList and changed code
7113 accordingly. Also changed SilcChannelClientEntry to include back-
7114 pointer to the channel so that client entry can use that structure
7115 as list as well and we have fast cross-reference to the channel.
7116 This change dramatically decreased the complexity of channel
7117 handling with client entry and vice versa (removed one extra
7118 loop when searching for channel entry from many functions).
7120 * Changed server->sim from table to SilcDList and changed code
7123 * NAMES command can now be used from user interface. It will show
7124 the user list on the channel, neatly.
7126 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7127 Code now saves realname of the user if it becomes available.
7129 * Renamed configure.in to configure.in.pre and made ./prepare
7130 script to automatically add correct version string to
7131 configure.in which it creates from configure.in.pre.
7133 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * NAMES command reply now shows users mode with the nickname when
7138 * Moved silc_client_ch[u]mode[_char] functions from
7139 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7140 place sucks, they are utility functions and should be in some
7143 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7145 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7148 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added TRQ (efficient deque and list library) into lib/trq. This is
7153 a very good list library that is currently used in the SILC. Defined
7154 SilcList API over the library because I didn't like the API very
7155 much. See lib/trq/silclist.h for the API and examples of how to
7156 use the API. Fixed various places in the code to use the new
7157 SilcList API. The SilcList is meant for lists that has a structure
7158 already defined as a list. It is not suitable to add just some
7159 context to the list (in TRQ, the context is the list actually).
7161 So, I defined SilcDList that can be used for the purpose where
7162 predefined list structure does not exit. This can be used as
7163 such list. Now some context just can be added to the SilcDList.
7164 Currently this list is not used in the SILC just yet, though there
7165 are a lot places where this can replace dynamically allocated
7166 tables and I will fix these places, later, to use SilcDList.
7167 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7168 and use TRQ internally).
7170 Also fixed some annoying warning messages that the original TRQ
7171 code generated. Also minor changes to TRQ's Makefile.in.
7173 * Added support for querying by Client ID to both WHOIS and
7174 IDENTIFY commands into server, as required by the protocol.
7176 * Removed method function pointers from SilcBuffer structure. They
7177 weren't used to anything and just increased the context size for
7178 no good reason. This change also made silc_buffer_alloc and
7179 silc_buffer_free functions inline functions.
7181 * Disabled command flooding detection support until it's fixed so
7182 that it accepts commands in but does not execute them more than once
7185 * Added silc_net_localhost(), to return local hostname, into
7186 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7187 that must be initialized before calling silc_client_init.
7189 * Added new function: silc_server_send_notify_on_channels to send
7190 notify messages to all channels client has joined. It is assured
7191 that the message is sent only once per client.
7193 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7194 lib/silcutil/silcutil.[ch] as silc_format function. The new
7195 function is generic and is used by server as well, not only by
7196 the logging routines.
7198 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7199 the provided version string was not acceptable. Added new function:
7200 silc_ske_check_version into lib/silcske/silcske.h. The function
7201 must be implemented by the application (client or server) and it
7202 does not reside in the SKE library. The function checks the version
7203 string remote end sent.
7205 * Added back pointers (to opaque context and to SilcSocketConnection)
7206 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7208 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7209 duplicate packet context structure.
7211 * Changed `notify' client operation to send same arguments as client
7212 receives from server except for ID's. ID's are mapped to correct
7213 ID entry and that is returned. Also, if channel entry is not sent
7214 by server but the notify is for channel the channel entry is sent
7215 to application (otherwise application doesn't know that it is for
7216 channel (library gets it from packet's Destination ID)).
7218 * Added silc_client_remove_from_channels into client library to
7219 remove a client from all channels it has joined to. Used when
7220 received SIGNOFF notify from server. Added also new function
7221 silc_client_replace_from_channels to replace old ID entry with
7222 new ID entry on all channels. Used when received NICK_CHANGE
7225 * Fixed ID Cache list handling in silc_idlist_get_client in
7226 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7227 to get (or query) client by ID.
7229 * Updated TODO list.
7231 * Added connection authentication status message defined by the
7232 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7233 support for these into the code in client and server side.
7235 * Added generic function silc_client_send_command to send any command
7236 with variable argument list. Application should use this function
7237 to send commands if the command functions provided by the library
7238 does not suite for the application's user interface needs.
7240 * Added new `failure' client operation. Application is notified about
7241 received failure packet if client is executing a protocol. In this
7242 case the protocol's execution has failed.
7244 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7245 is required by the protocol.
7247 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7248 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7251 * Added status flag to SilcSKE object to indicate realtime status
7252 of the SKE protocol.
7254 * Application receives now exactly same command reply arguments as
7255 the library receives from server. However, if ID is received the
7256 corresponding ID entry is returned to the application (eg. Client
7257 ID is mapped to correct SilcClientEntry entry and that is returned).
7258 Changed command_reply client operation due to this change.
7260 * Changed all ID's in commands and in command replys as ID Payloads.
7261 Change affected both client and server side codes.
7263 All ID's sent in SILC network (with execption of ID's in SILC
7264 Packet header) are sent in ID Payload to support variable length
7267 * Server now notifies nick changes and notifies all clients on
7268 the channels about the new nickname (about the new Client ID,
7271 * Implemented CMODE command to change channel modes. Supports all
7272 channel modes defined by the protocol specs except ban and invite
7273 lists. (Also, private channel key mode is supported but support for
7274 setting private channel key in client is missing, thus, this mode
7275 has no effect on client side (except that server requires that the
7276 client uses private channel key and normal channel traffic does not
7279 Also, invite mode works per se, but INVITE command does not work
7280 yet correctly, so you can set channel as invite only channel but
7281 inviting clients to the channel does not work (it is yet to be
7282 thought what's the best way to do it).
7284 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7285 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7286 Implemented CUMODE command to change user's mode on the channel.
7287 Supports all modes defined by the protocol specs.
7289 * Added NAMES command reply to return users modes on the channel.
7291 * Removed unnecessary and slow ciphers from lib/silccrypt.
7293 * Set SO_KEEPALIVE option to connection sockets by default.
7295 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7297 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7298 redefined the Notify Payload into protocol specs.
7300 * Added silc_id_payload_parse_id to get ID directly from raw
7303 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7306 accept searching by Client ID as well.
7308 * Added support for LEAVE and SIGNOFF notify types in client library.
7310 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7311 to parse ID Payload from raw data.
7313 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7315 * Added flags parameter into silc_ske_assemble_security_properties
7316 function in lib/silcske/silcske.[ch].
7318 * Changed notify client operation to fit better for notify messages
7319 sent by server. The notify payload received from server is now
7320 passed to the application (after parsing it to SilcNotifyPayload).
7321 It is application's responsibility to retrieve the arguments
7322 from the payload and show the message the way it wants. The message
7323 sent by server is implementation specific.
7325 * Changed public keys to comply with the protocol specification.
7326 Old public keys are not supported anymore and are not compatible.
7328 * Removed nickname from Channel Payload as the latest draft removed
7329 it. The client must resolve the nickname from the NAMES command
7330 reply received when it joined the channel.
7332 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7334 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Fixed some errors in protocol specification drafts.
7338 * Created lib/silccore/silcnotify.c to implement Notify Payload
7339 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7340 generic payloads described by protocol specifications. The file
7341 includes implementations for ID Payload and Argument Payload.
7343 * Changed Command Payload implementation to use the new Argument
7344 Payload. Changed command_xxxx_payload to command_payload_xxxx
7345 to comply with SILC coding conventions.
7347 * Added suppport for Argument Payload handling in Notify Payload
7348 implementation as protocol requires it. Added the new support
7349 into server and client lib as well.
7351 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7353 * Added support for multiple nicknames on same channel. [n] is
7354 added locally to the nickname if there are more than one same
7355 nicknames on the channel.
7357 * Server now sends all nicknames that matched WHOIS request.
7358 Client also shows the list received from server.
7360 * Added TOPIC command to client side. User can now set and show
7361 current topic on channel.
7363 * Added MOTD command to client and server. Also, server sends the
7364 motd when client connects to the server.
7366 * Changed version strings to comply ISO 8601.
7368 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Fixed protocol error handling in client library. It should now
7371 cope even if the SKE fails for some reason.
7373 * Made new protocol specification drafts for submitting to IETF.
7375 * Implemented TOPIC command to server in silcd/command.c.
7377 * Added two new notify types into lib/silccore/silcnotify.h:
7378 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7379 notify nickname change and topic setting/change on a channel.
7381 * API change of command_reply operation in client library. The
7382 application gets now the status type received from server as well.
7384 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7388 * Cras fixed and optimized the packet handling even further and
7389 it should work now. Minor change to the prototype of function
7390 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7392 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7394 * Added new function into lib/silcutil/silcschedule.[ch]:
7395 silc_schedule_with_fd to select() a specified fd. The function
7396 returns after timeout expires or data arrives or goes. The
7397 function is used by packet routines to wait that all data is
7398 received from network.
7400 * Fixed data reading from network in lib/silccore/silcpacket.c.
7401 The code now assures that all data is read from the fd and then
7402 continues packet processing. This was a bug fix since the code
7403 used to drop some data in some circumstances.
7405 * Added new function into lib/silcclient/client.[ch]:
7406 silc_client_start_key_exchange to start key exchange after
7407 connection has been established to server. The code internally
7408 now uses this funtion but its main purpose was to provide it
7409 for applications that perform their own connecting. After
7410 application has created a connection it merely calls this
7411 function to start the key exchange between client and server.
7412 The library takes care of everything else after that.
7414 Updated also lib/silcclient/README to explain the usage of
7417 * Do not send to application information that connection has
7418 been established. Application gets notified it by connect
7421 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7423 * Applied cras's patch to add silc_schedule_one function. The
7424 function runs scheduler once and returns.
7426 * Fixed the scheduler after cras messed it up. The timeout
7427 handling works now as it's supposed to work.
7429 * Added into lib/silccore/ silcnotify.h to include notify
7430 message types support. Changed silc_server_send_notify*
7431 functions, in server.[ch], to support those new notify types.
7432 Added the support for the notify types into client library,
7433 as well. Added new notify client operation into ops.h in
7436 * Changed silc_server_packet_send_to_channel to send normal
7437 packets instead of just channel message packets. The function
7438 is now used to send the notify packets to channels. It is not
7439 used to send channel message packets anymore, as server never
7442 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7443 va_arg()s as it seems to require it nowadays. I guess, if SILC
7444 is compiled with older va_arg() the new code should work anyway.
7446 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * Splitted core library. Core library (lib/silccore) includes
7449 now only SILC protocol specific core (and common) components.
7450 Created new utility library (lib/silcutil) that includes more
7451 generic purpose stuff. The stuff for util library was taken
7452 from the old core library. This was minor and easy split.
7454 * Created SILC Client Library (lib/silcclient) that includes
7455 implementation of the SILC client without user interface. This
7456 was major move from silc/ directory. The code has been changed
7457 so that it is transparent towards the user interface. The
7458 silc/ directory includes now the same user interface as before
7459 and it uses the new client library. Read lib/silcclient/README.
7460 Basicly, the client library performs everything else related
7461 to SILC except user interface handling. Also, configuration
7462 files are considered to be part of user interface and library
7463 does not handle them.
7465 This change also changed a lot of structures, function naming etc.
7466 Most important change was that SilcClientWindow object was
7467 renamed to SilcClientConnection in the client library. Created
7468 also new file lib/silcclient/ops.h. Also added new files
7469 silc/local_command.[ch] and silc/client_ops.[ch].
7471 All these changes were made to make it easier for user interface
7472 designers to create what ever user interface for the SILC client
7475 It is also expected that the server will be moved to lib
7476 directory as well and SILC Server Library will be created;
7477 sometimes in the future.
7479 * Removed Local commands from lib/silccore/silccommand.h as
7480 they are application specific and new client library does not
7481 handle any of those anymore.
7483 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7484 old client implementation in silc/.
7486 * Added support for callback functions in SILC_LOG_* macros.
7487 Application can now set its own callbacks that will be called
7488 instead of using the default functions that will always print
7489 the debug messages to stderr (or stdout). Also, debugging can
7490 now be disabled by setting silc_debug to FALSE and re-enabled by
7491 setting it to TRUE. Note, that logging will still work even
7492 if debugging is disabled.
7494 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7495 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7496 silc_log_reset_debug_callbacks.
7498 * To enable debugging in silc client one must give now -d
7499 option on command line.
7501 * Changed silc_schedule_init to automatically allocate task queues
7502 if they are not allocated before calling it.
7504 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Added GMP 3.1 into math library.
7508 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7511 a channel in SILC network. The packet is used by servers and
7512 routers to notify other routers that user has left a channel.
7513 This little feature was missing until now. Added the feature
7514 to protocol specification as well.
7516 Added functions: silc_server_send_remove_channel_user and
7517 silc_server_remove_channel_user into server.[ch].
7519 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7520 lib/silccore/silcpacket.h. However, they are not implemented
7523 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Fixed joining to a channel and sending channel messages
7526 between server and router. The channel message sending should
7527 now work inside a cell.
7529 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Fixed the private message sending between server and router.
7532 The private message sending should now work inside a cell.
7534 * Added silc_server_replace_id into server.[ch] to replace
7535 existing ID in the SILC network.
7537 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7538 and silc_idlist_replace_server_id into idlist.[ch] in server.
7540 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7542 * Fixed the server to server connections. Server can again now
7543 connect to router. Router to router connections probably does
7546 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7548 * Added dynamic protocol registering support. Now protocols can
7549 registered and unregistered on the fly. Patch by cras.
7551 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7553 * Added lib/contrib directory to hold routines that some platforms
7554 don't have but are needed by SILC.
7556 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7557 into lin/contrib to provide getopt() and getopt_long() for
7558 those who don't have it.
7560 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7562 * Added AWAY command to client. When away message is set and
7563 client receives a private message packet the client automatically
7564 replies to the sender with the away message.
7566 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7567 bug seemed to be the cause of recent problems when compiling
7570 * Added version detection support to SKE protocol specification
7571 and added the new changes to the SKE implementation as well.
7572 There were other minor changes in the SKE protocol as well.
7574 Many changes in lib/silcske/silcske.[ch] and in
7575 lib/silcske/payload.[ch].
7577 * Added ^U functionality, clear input line. Patch from cras.
7579 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7581 * Mainly small bugfixes on core library. Fixed some debugging
7582 logging and buffer overflow in silclog.c.
7584 * Updated config.sub and config.guess on the distribution tree.
7586 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7588 * Added command lagging support in server. Client may execute
7589 commands now only once in two seconds.
7591 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Optimized packet reception. MAC computation and checking is now
7594 also more optimized. A lot previously duplicated code is now
7595 used as generic by both client and server.
7597 * Fixed key pair generation in clientutil.c
7599 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Added into lib/silccore/silcbufutil.[ch] new function;
7602 silc_buffer_realloc.
7604 * Moved generic packet sending/encryption functions to
7605 lib/silccore/silcpacket.[ch] from client and server. Some
7606 rewriting of the functions.
7608 * Moved all generic packet reception/decryption functions to
7609 lib/silccore/silcpacket.[ch] from client and server. The
7610 packet processing is now much cleaner in both client and server.
7611 These were major changes in both client and server.
7613 * Created many common functions in server to do packet sending.
7614 Previously code were duplicated a lot, this has been removed
7617 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7619 * Rewrote major parts of the ID cache system. Don't know
7620 whether it is better now or not but at least the API is more
7623 * Major rewrite on ID cache stuff on client because of the ID
7624 cache API changes. Added idlist.c to client.
7626 * Also major rewrite on ID cache stuff on server as well.
7627 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7628 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7629 in hand, instead they are all put into the ID cache system now.
7630 All server_idlist_* routines uses ID cache now instead of
7631 traversing its own lists (those lists does not exist anymore).
7632 SilcIDList though still exists. Also, SilcXXXEntry's are
7635 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7637 * Finally made the SKE implementation compliant to the protocol
7638 specification. All mp integers are now binary encoded as
7639 opposed being HEX encoded.
7641 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7644 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7645 functions: silc_[encode/decode]_pem. Also added function
7646 silc_encode_pem_file to PEM encode with newlines ('\n') for
7649 * SILC public keys are now encoded either PEM or binary. Same
7650 option is for private keys as well. By default private keys
7651 are binary encoded and public keys PEM encoded. Silly HEX
7652 encoding were removed.
7654 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7655 function to create fingerprints.
7657 * Fixed a bug in SHA1; does not change the original data anymore.
7659 * Partly implemented INFO command on client and server side.
7660 Fixed CLEAR command. Changes to SERVER command; show current
7661 server(s) when giving command without arguments. Added
7662 VERSION command to client.
7664 * Added check to server that unregistered connections cannot
7665 execute commands (unless it is specificly allowed).
7667 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7669 * Fixed screen refresh.
7671 * Fixed channel joining bug from client. On some circumstances
7672 client tried to join to a channel it had already joined.
7674 * Added public key verification process into client's protocol.c.
7675 The client now verifies the public key from user and saves
7676 it into ~./silc/serverkeys/ directory.
7678 Added into: clientutil.[ch]: silc_client_verify_server_key.
7680 * Changed SKE protocol's silc_ske_initiator_finish function
7681 to accept callback function that verifies the received public
7682 key. Removed old silc_ske_verify_public_key function.
7684 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7686 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7687 silc_pkcs_private_key[_data]_set.
7689 * Made the password and public authentication more cleaner in
7690 server's protocol.c.
7692 * Removed historic and obsolete protocol `channel_auth' from
7693 both client and server.
7695 * Removed wrong way of sending command status messages from
7696 server to client in server's command.c. The old way violated
7697 protocol specification.
7699 Changes to silccore/silccommand.[ch]: removed
7700 silc_command_encode_status_payload -> not needed anymore,
7701 changed silc_command_encode_payload_va to accept extra
7702 argument on variable argument list. The argument type must
7703 now be provided to the function. Also, added new function:
7704 silc_command_encode_reply_payload_va which is same as
7705 normal command_encode_payload_va except command status type
7706 is provided as extra argument.
7708 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7710 * Added ~./silc directory handling. The directory includes the
7711 public and private keys for the client.
7713 Added silc_client_check_silc_dir, silc_client_create_identifier
7714 and silc_client_load_keys.
7716 * Implemented SILC protocol compliant public key. Added public
7717 and private key saving to and loading from files.
7719 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7720 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7721 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7722 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7723 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7725 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7726 silc_pkcs_load_[public/private]_key.
7728 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Added silc_server_get_route (route.[ch]) to get connection
7731 data for the fastest route for given ID.
7733 * Implemented INVITE command on client and server. The command
7734 were re-defined in the SILC Protocol Specification and the
7735 implementation now complies with the specification.
7737 * Implemented PING command on client and server.
7739 * Implemented NAMES command on client and server. The server side
7740 supports currently only normal server not router server yet.
7741 Some changes to NAMES definition in SILC protocol specification.
7743 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Implemented LEAVE command on client and server.
7747 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7748 again. This change was made to the protocol as well. Server
7749 should not violate the protocol specification anymore.
7751 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7753 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7754 was tested. SOCKS4 was not but should work anyway.
