8 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
9 files are lib/silcutil/silcstrutil.[ch].
11 * Defined that the security property fields in SKE SHOULD be
12 UTF-8 encoded, defined that version string MUST be US-ASCII
13 encoded, defined that passphrases sent in connection
14 authentication protocol MUST be UTF-8 encoded. Implemented
15 these to the client and server. Defined also that other
16 passphrases sent in the protocol MUST be UTF-8 encoded.
17 Affected files are lib/silcske/silcske.c,
18 lib/silcclient/protocol.c, silcd/protocol.c,
19 silcd/serverconfig.c, and lib/silccore/silcauth.c.
21 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
23 * Upgraded the protocol version to 1.1, updated protocol specs
26 * Added the nickname as new argument to NICK_CHANGE notify and
27 added it to protocol specs and implemented it to client and
28 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
29 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
30 lib/silcclient/client_notify.c.
32 * Added the killer's client ID to the KILLED notify and added
33 it to protocol specs and implemented it to client and server.
34 Protocol TODO #13. Affected files are silcd/command.c,
35 silcd/packet_receive.c, packet_send.[ch],
36 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
37 The killer's client entry is now returned to application in
38 the `notify' client operation.
40 * Fixed the Max Argument fields that had too large value set
41 in the protocol specs. Protocol TODO #14.
43 * Added the LEAVE command reply to return the ID of parted
44 channel. Updated protocol specs and implemented it to the
45 client and server. Protocol TODO #15. Affected files are
46 silcd/command.c, lib/silcclient/command_reply.c. The channel
47 entry is now returned to application in the `command_reply'
50 * Rewrote the version SKE version checking in client libary
51 and in server to use the silc_parse_version_string. Affected
52 files are lib/silcclient/protocol.c, silcd/protocol.c.
54 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
55 commands that was missing it, and updated protocol specs and
56 the server implementation. Protocol TODO #10. The affected
57 file is silcd/command.c.
59 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
60 generic reply to a generic request (REQUEST flag), and
61 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
62 way. A draft-riikonen-silc-flags-payloads-00.txt is written
63 to define the payload for DATA flag. Added the flags to
64 the implementation. Protocol TODO #9. Affected file is
65 lib/silccore/silcchannel.h.
67 Changed the client library to return the message length
68 to application as well in the channel_message and private_message
69 client operations. Affected files are
70 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
71 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
72 and lib/silcclient/client_ops_example.c.
74 * Added two new channel modes: SILC_CMODE_SILENCE_USERS

76 the channel. Updated protocol specs and impelemented this
77 to client and server. Protocol TODO #6. Affected files are
78 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
79 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
81 Added new options m and M to CMODE command in Irssi SILC
82 client to set these modes.
84 * Deprecated all administrative commands from SILC protocol
85 since they are highly implementation specific commands.
86 Updated protocol specs. Moved the old commands in
87 implementations to private range of command types. Affected
88 files are silcd/command.c, lib/silcclient/command.c and
89 lib/silcclient/command_reply.c. Protocol TODO #8.
91 * Fixed a bug in server where sending unknown command crashes
92 the server. Affected file silcd/command.c.
94 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
96 * Added SILC_PROTOCOLVERSION macro to check protocol version
97 of a socket connection. The affected file is
98 lib/silcutil/silcsockconn.h.
100 * Added better error logging in rekey protocol. Affected file

104 file lib/silcske/payload.c.
106 * Fixed the rekey protocol with PFS, which was totally broken.
107 Affected file silcd/protocol.c.
109 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
111 * Some client implementations quit network by doing first LEAVE
112 and then immediately SIGNOFF (like Bombyx). We now do check
113 after a short time after LEAVE notify and check whether the
114 client is still valid after LEAVE, and if not we remove it from
115 cache. Affected file is lib/silcclient/client_notify.c.
117 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
119 * Merged version 1.1.4 of zlib. Even if it not currently in use,
120 it's good not to have security holes here.
122 * Fixed a negative refcount situtuation for the config context.
123 Affected file is silcd/serverconfig.c.
125 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
127 * ROBOdoc documented lib/silcutil/silcutil.h.
129 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
131 * Optimized even more the SilcPacketContext structure. Now
132 totally saved 16 bytes of memory per context after optimization.
133 Affected files are lib/silccore/silcpacket.[ch].
135 * Made strict checks for valid SILC IDs. Affected file is
136 lib/silccore/silcid.c.
138 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
140 * Changed the object argument for silc_cipher_register,
141 silc_hash_register, silc_hmac_register and silc_pkcs_register
142 to const. Affected files are lib/silccrypt/silccipher.[ch],
143 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
145 * Changed the silc_get_username and silc_get_real_name to
146 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
148 * Fixed the Irssi SILC Client to use the silc_get_username and
149 silc_get_real_name insted of glib routines since the glib
150 routines only corrupt stack. Fixes the Irssi SILC to work in
151 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
153 * Fixed the Irssi to not use g_get_home_dir since it crashes
154 or returns garbage on cygwin and corrupts stack. Added function
155 get_home_dir to Irssi routines. Affected files are
156 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
158 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
160 * Made some structure optimizations. SFTP memory FS MemFSEntry
161 entry structure. Optimized SilcTask structure. Optimized
162 SilcPacketContext structure.
164 Affected files lib/silcsftp/sftp_fs_memory.c,
165 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
167 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
169 * And yet again reverted back the config thing since Johnny
170 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
173 * Fixed memory leaks from config object. Affected files are
174 silcd/serverconfig.[ch].
176 * Added support for adding new connections to the server in rehash.
177 After rehash they take effect.
179 Added support for changing the maximum allowed connections in
180 rehash. The number can grow but going smaller is not supported.
182 Added function silc_server_num_sockets_by_remote to the
183 silcd/server_util.[ch].
185 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
187 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
189 * Added preliminary checking during config parsing for a valid
190 public/private key and removed further checks in the code.
191 Affected files are silcd/serverconfig.[ch], server.c.
193 * Moved functions silc_server_drop() and silc_server_daemonise()
194 from server.c to silcd.c since they are stricly related to
195 the application activity.
197 * Reverted a small part of the automatic ref/unref since
198 it caused a double unref in some situations. Affected
199 files are silcd/silcd.[ch], server.c, serverconfig.c.
201 * Added some .cvsignore files in the lib directory.
203 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
205 * Fixed silc_net_gethostbyaddr to correctly resolve by
206 address. Affected file lib/silcutil/silcnet.c.
208 * Fixed the notify relaying to client. The HMAC to be used
209 with relayed packets ws wrong and caused decryption failure
210 at the client end. Affected file is silcd/packet_receive.c.
212 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
214 * Created new branch silc_protocol_1_0_branch.
216 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
218 * Changed the silc_server_config_* routines to be SilcServer
219 independent. They are now officially application specific code
220 and not part of generic server implementation. Affected files
221 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
223 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
225 * Added automatic referencing of config context in the
226 silc_server_config_alloc, and automatic unreferencing in the
227 silc_server_config_destroy. Affected files are
228 silcd/serverconfig.[ch], silcd/silcd.c.
230 * Fixed the silc_log_quick handling in the logging routines.
231 It didn't log quickly when it was TRUE. Affected file is
232 lib/silcutil/silclog.c. Also the flush delay was set even
233 if it was 0 in config file. Affected file is
234 silcd/serverconfig.c.
236 * Added support for changing key pair of the server in rehash.
237 Affected file silcd/server.c.
239 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
241 * Fixed the TOPIC_SET notify to not cras. It changed the topic
242 too early, before getting the channel entry. Affected file
243 is silcd/packet_receive.c.
245 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
247 * Added functions silc_server_config_[ref/unref], these are used
248 to prevent that the config object is destroyed.
250 No longer directly affect global variables silc_log_quick and
251 silc_log_delay, they are first cached inside the config object
252 and then applied with silc_server_config_setlogfiles().
254 silc_server_config_set_defaults() is now internal to
255 serverconfig.c, there are no reasons to show this internal stuff
258 Affected files are silcd/serverconfig.[ch].
260 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
261 fprintf's to stderr, since some code may be executed again after
262 the server went into the background. Affected files are
265 * Added rehash support. Added function silc_server_rehash() that
266 will perform all the basic tasks of the rehashing procedure.
268 * Added command line option `-x, --hexdump'. This will enable the
269 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
270 The option `--hexdump' implies `--debug'.
272 * Fixed a bad bug in the logging APIs (silcutil library) where
273 the application would crash after calling silc_log_reset_all().
275 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
277 * Fixed the KICKED notify handling in client library to
278 correctly remove the channel and all entries from the
279 channel when I was kicked. This bug crashed the client.
281 Fixed yet another but in KICKED notify handling to remove
282 the kicked client correctly from the channel.
284 Affected file is lib/silcclient/client_notify.c.
286 * Fixed a minor bug in looking up correct client entry
287 in KICKED notify in server. Affected file is
288 silcd/packet_receive.c.
290 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
291 sources correctly to distribution. Fixes --with-gmp option.
293 * Removed the manual rehashing from ID Cache, and changed it
294 to use the SILC Hash Table's auto rehash feature. Affected
295 file is lib/silccore/silcidcache.c.
297 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
299 * Fixed a bug in the silc_client_nickname_format function that
300 handles the multiple same nickname formatting. Two clients
301 with same nickname caused problems after the first one left
302 and rejoined. It didn't format the nickname correctly.
303 Affected file is lib/silcclient/idlist.c.
305 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
307 * Don't change the topic if olod topic is same as new one.
308 Affected file is silcd/packet_receive.c.
310 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
312 * Added cross-reference support to the SILC Documentation
313 generator. All types across all HTML files are now cross-
314 referenced. Affected files util/robodoc/generator.c and
315 scripts/silcdoc/silcdoc.
317 * Added file lib/silcutil/silctypes.h to include all the
318 arithmetic type definitions and some macros. Removed
319 includes/bitmove.h and moved macros to silctypes.h.
321 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
323 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
325 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
327 * Added `type' argument to silc_id_payload_parse_id function which
328 now returns the type of the ID to the sent pointer. Affected
329 file is lib/silccore/silcid.[ch].
331 * Added check for CMODE_CHANGE notify type that mode change is
332 allowed by the sender. Affected file silcd/packet_receive.c.
334 * Added check for CUMODE_CHANGE notify type that mode change is
335 allowed by the sender. Affected file silcd/packet_receive.c.
336 Added the ID type as CUMODE_CHANGE notify type as argument
337 to the `notify' client operation. Affected files are
338 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
340 * Added function silc_client_add_server to the client library.
341 Added support for resolving also channel and server info when
342 received unknown entity in notify packet. Affected files are
343 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
345 * Added function silc_command_get_status to return the command
346 status from the command reply's argument payload. Affected files
347 are lib/silccore/silccommand.[ch].
349 * Added check for KICKED notify type that the kicking is
350 allowed by the client. Affected file silcd/packet_receive.c.
352 * Created function silc_get_input which can be used to get input
353 (echo on or off) from user on command line. Affected files are
354 lib/silcutil/silcutil.[ch].
356 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
358 * Optimized silc_server_packet_relay_to_channel function.
359 Added new function silc_channel_message_payload_encrypt which
360 can be called directly if channel message payload needs to
361 be encrypted and is already encoded (no need to call _encode
362 function). Packet relaying is now done by router without any
363 extra memory allocations. Affected files are
364 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
367 * Fixed the INVITE notify handling. It took wrong arguments
368 as invite list and invite delete. Affected file is
369 silcd/packet_receive.c.
371 * Added check for TOPIC_SET notify type that the topic change is
372 allowed by the client. Affected file silcd/packet_receive.c.
374 * Added check for INVITE notify type that inviting is allowed by
375 the client. Affected file silcd/packet_receive.c.
377 * Changed the silc_server_client_on_channel to return the
378 SilcChannelClientEntry as well. Moved the function
379 silc_server_check_cmode_rights to server_util.[ch].
380 Affected files are silcd/server_util.[ch], silcd/command.c.
382 * Added function silc_server_check_umode_rights to check whether
383 changing client's user mode is allowed. Added check for
384 UMODE_CHANGE notify type that the umode change is allowed
385 by the client. Affected files are silcd/server_util.[ch],
386 silcd/packet_receive.c and silcd/command.c.
388 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
390 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
391 ID length. It ignored that ID can be IPv6 based as well.
392 Affected file lib/silccore/silcpacket.h.
394 * Fixed the silc_id_id2str and silc_id_str2id to take the
395 IPv6 address offset's into consideration. Affecte file is
396 lib/silccore/silcid.c.
398 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
400 * Fixed the internal Unix scheduler functions to check for
401 NULL context they may receive. The affected file is
402 lib/silcutil/unix/silcunixschedule.c.
404 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
406 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
407 can specify different directory with --home command line
408 parameter. Affected files irssi/src/silc/core/client_ops.c,
411 * SILC-specific commands aren't now executed if the active server
412 isn't of SILC-type, so there won't be problems with having
413 IRC and SILC protocol support in same client. Affected files
414 irssi/src/silc/core/silc-channels.c, silc-servers.c,
417 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
419 * Improved the signal support in SILC Schedule. Added new
420 function silc_schedule_signal_call which is used by application
421 to mark a signal to be called. It is now safe to perform
422 any kind of tasks in signal callbacks since it is guaranteed
423 that the application specified signal callback is called
424 after the signal is over. Affected files are
425 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
427 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
429 * Added `name' field to SilcChannelPrivateKey to represent
430 application given name for the key. Moved also the context from
431 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
432 Added the `name' argument also to the function
433 silc_client_add_channel_private_key.
435 Added function silc_client_current_channel_private_key to set the
436 current channel private key in use.
438 Added "change" command to KEY command which can be used to change
439 the current channel private key. Bound the command also to
442 Also affected files lib/silcclient/client_channel.c,
443 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
445 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
447 * Added silc_rng_get_byte_fast function in to the
448 lib/silccrypt/silcrng.[ch].
450 * Changed the interface of silc_packet_assemble and the
451 silc_packet_send_prepare. If silc_packet_assmble is now
452 called the application does not call silc_packet_send_prepare
453 because the library will call it automatically. These
454 interfaces now also return a reference to the outgoing buffer
455 which includes the assembled packet, which the application can
456 use to encrypt the packet.
458 Affected files are lib/silccore/silcpacket.[ch],
459 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
460 silcd/packet_send.c, server_backup.c and packet_receive.c.
462 * Fixed a packet sending bug on very high load, where outgoing
463 packet queue wasn't handled correctly and packets got corrupted.
464 Affected files are lib/silcutil/*/silc*sockconn.c,
465 lib/silcclient/client.c and silcd/server.c.
467 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
469 * Added macro SILC_PACKET_DATALEN which can be used during
470 packet assembling to check whether the data to be added to
471 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
472 len is truncated until it fits it.
474 Added checks for maximum length of channel message payload and
475 private message payload also.
477 Added checks for maximum packet length in server and in
480 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
481 lib/silcclient/client.c, lib/silccore/silcchannel.c and
482 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
483 lib/silcclient/client_prvmsg.c.
485 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Added silc_server_packet_queue_purge call to the
488 silc_server_disconnect_remote to assure that all data in the
489 queue before disconnecting is sent to the network. Affected
492 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
494 * Added the deleting of server's own ID cache entry to the
495 silc_server_free function. Free also everything else that
496 has been allocated in silc_server_init. The affected file
499 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
501 * Added functions silc_parse_version_string, silc_version_to_num,
502 and silc_ske_parse_version to parse SILC protocol style version
503 strings. Affected files lib/silcutil/silcutil.[ch] and
504 lib/silcske/silcske.[ch].
506 * Added new configuration params: version_protocol, version_software
507 and version_software_vendor to specify what version the remote
508 host must at least be to be able to connect to server. The vendor
509 string can be regex matched too. Added new function
510 silc_server_connection_allowed to check maximum number of allowed
511 connections, and allowed versions for incoming connections.
512 Affected files are silcd/server.c, server_util.[ch] and
515 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
517 * Added preliminary support for signals in scheduler. The
518 signals we care about are now blocked always when the scheduler
519 is locked. This way we can synchronise the use of signal with
520 scheduler. It is guaranteed that when signal occurs the scheduler
521 is not locked, and thus new tasks can be safely added to the
524 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
525 to silc_schedule_internal_init and silc_schedule_internal_uninit.
526 Added new platform specific routines
527 silc_schedule_internal_signals_[un]block and
528 silc_schedule_internal_signal_[un]register.
530 Added new functions to SILC Schedule API:
531 silc_schedule_signal_[un]register. Each signal that application
532 is going to use should be registered to the scheduler.
534 Affected files are lib/silcutil/silcschedule.[ch],
535 lib/silcutil/*/silc*schedule.c.
537 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
539 * Check for unauthenticated client and server in the
540 silc_server_new_client and silc_server_new_server functions.
541 Affected file silcd/packet_receive.c.
543 * Added function silc_string_is_ascii to check whether given
544 string is 7-bit ASCII string. Affected files are
545 lib/silcutil/silcutil.[ch].
547 * Added function silc_id_is_valid_server_id into the
548 silcd/serverid.c and added checking for valid Server ID's in
549 silc_server_new_server. The Server ID must always be based
550 on the server's public IP address.
552 * Added logging of DISCONNECT packet message in the server.
553 Affected file silcd/server.c.
555 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Changed all library interfaces that use Global RNG to also
558 accept SilcRng as argument. Affected files are
559 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
560 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
561 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
562 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
565 * Added function silc_pkcs_generate_key to the
566 lib/silccrypt/silcpkcs.[ch] for applications so that they
567 don't need to do pkcs->pkcs->init calls anymore.
569 * Remove SilcSocketConnection from the SFTP API since it really
570 wasn't needed there. The application has the information
571 saved in its contexts anyway and the SFTP layer doesn't need
572 know about it. Affected files lib/silcsft/silcsftp.h and
573 lib/silcsftp/sftp_[server/client].c.
575 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

579 lib/silcutil/silcutil.c.
581 * On EPOC the global crypto module lists are not used at all
582 in the crypto library. Added support for using the constant
583 algorithm list on EPOC. Affected files are
584 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
587 * Fixed the handling of third parameter of KICKED notify, since
588 it was mistakenly updated to SILC Protocol 1.0 even though it
589 is to be included in 1.1. Since it is not in 1.0 it is not
590 mandatory, and this fix now handles it only if it is provided,
591 and it is not error if it is not provided. Affected file
592 lib/silcclient/client_notify.c.
594 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
596 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
597 client. Affected file irssi/src/silc/core/client_ops.c.
599 * Merged with Irssi 0.8.4 from irssi.org CVS.

608 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
610 * $usermode, $cumode and $cumode_space expandos shouldn't do
611 anything with non-SILC server records. Affected file
612 irssi/src/silc/core/silc-expandos.c
614 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
616 * Fixed the silc_net_check_[host/local]_by_sock to support
617 IPv6 bound sockets as well. Now they can return IPv6 addresses
618 as well. Affected file lib/silcutil/silcnet.c.
620 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
621 Affected lib/silcutil/unix/silcunixnet.c.

624 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
626 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Added silc_hash_public_key and silc_hash_public_key_compare
629 functions to be used with SilcHashTable. They can be used to
630 hash public keys and compare public keys in hash table. Affected
631 file lib/silcutil/silcutil.[ch].
633 * Added support for specifying multiple public keys for Client
634 connection section in server configuration file. This makes it
635 possible to accept multiple public keys from same host, or to
636 make a section that accepts any incoming host, and have the
637 accepted public keys listed in the section.
639 Added functions silc_sever_[find/get]_public_key, added the
640 support for this actually to all connection sections but only
641 the Client section is currently allowed to specify multiple
644 Affected files are silcd/server.c, server_internal.h,
645 command.c, protocol.c, server_util.[ch], packet_receive.c.
647 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

654 to stderr with the debug output.
656 Made silc_log_reset_all() flushing all channels before returning.
657 Also fixed some documentation typos.
659 Affected files are lib/silcutil/silclog.[ch].
661 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
663 * Fixed the server to check correctly the amount of connections
664 from single host, by checking also the type of the connection.
665 Fixed also the comparison of number of connections and number
666 of allowed connections. Affected files are silcd/server.c,
669 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
671 * Fixed the USERS command reply to save the user's mode on the
672 channel as well. Fixed JOIN command reply to check whether a
673 client is on channel already and not join it twice. Affected
674 file lib/silcclient/command_reply.c.
676 * Added new file silc-expandos.c into irssi/silc/core/ to return
677 various stuff for various signal for the statusbar etc. updating.
678 Now Irssi SILC client prints channel user modes etc. on the
681 * The user mode (like server/router operator changes) is now shown
682 on the Irssi SILC client's statusbar. The affected files are
683 irssi/src/silc/core/client_ops.c, silc-expandos.c.
685 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

717 * Removed 0.6.x backwards support.
719 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
721 * Changed all integer type names:
722 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
723 to avoid collisions with other libraries using same type names
726 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Added `prefer_ipv6' argument to the functions
729 silc_net_gethostbyname[_async]. If it is TRUE it will return
730 IPv6 address over IPv4. If FALSE IPv4 address is returned
731 even if IPv6 address was found. Affected files
732 lib/silcutil/silcnet.[ch].
734 * Added support silc_net_create_connection[_async] to fallback
735 to IPv4 address if IPv6 address could not be used (like if

748 application does not need to define them. Affected file
749 includes/silcincludes.h.
751 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
752 old name went against naming convention. Applications now
753 include "silcclient.h" instead of "clientlibincludes.h".
754 Removed includes/clientlibincludes.h, it is redundant now.
756 * Renamed includes/version.h to silcversion.h.
758 * Added really preliminary support for OS/2 into the util
759 library. Only thread & mutex API is implemented, others
760 are still to be implemented. Created the lib/silcutil/os2/
761 directory. Created also file includes/silcos2.h.
763 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
765 * Added preliminary BeOS support into the util library.
766 Created lib/silcutil/beos/, and implemented all the needed

792 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
794 * Added `user_count' to the SilcChannelEntry which now tells the
795 number of users on the channel. The user count is now saved
796 in normal server of global channels as well. Affected files
797 silcd/server.c, idlist.h, packet_receive.c and command.c.
799 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

810 client_entry->channels hash table everytime nick is changed.
811 Affected file lib/silcclient/client.c.
813 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
815 * ROBOdoc documented the lib/silcske/silcske.h, and improved
816 the SKE interface a bit.
818 * Fixed padding problem in PKCS#1. The padding was not actually
819 random since the random number generator was used incorrectly.
820 This security bug affects only when encrypting with PKCS#1, and
821 it is not currently used at all in SILC. SILC only use signing
822 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
824 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

841 Optimized the use of SKE Mutual flag usage. Use it only
842 if connection authentication protocol is not based in public
845 Renamed all SilcServerConfigSection* to SilcServerConfig*
846 to have a bit shorter names.
848 Affected files silcd/serverconfig.[ch], server.[ch], and

885 Affected files irssi/src/silc/core/silc-core.c,
886 irssi/src/fe-text/silc.c.
888 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
890 * Added new configuration options and blocks:
891 keepalive_secs, reconnect_count, reconnect_interval,
892 reconnect_interval_max, reconnect_keep_trying and
893 require_reverser_lookup. Added ConnectionParam block, and
894 implemented the connection parameters when connecting as
895 initiator and when accepting connections as responder.
897 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
898 whether given configuration value has been given already.
900 Affected files silcd/serverconfig.[c], server.[c].

903 algorithm parts and created new file silcalgs.conf, that
904 is now included from the example_silcd.conf.in.
906 * Optimized the silc_server_connect_to_router_second to take
907 the connection configuration object from the SilcServerConnection
908 object instead of finding it during the connecting phase.
909 Added the configuration object to SilcServerConnection struct.
910 Affected files silcd/server_internal.h, server.c.
912 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
914 * Add the client on channel after it was resolved at the
915 channel message receiving, and it was not already on the
916 channel. Affected file lib/silcclient/client_channel.c.
918 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

926 * Unified the serverconfig.[ch]'s helper function interface.
927 Affected file silcd/serverconfig.[ch].
929 * Removed doc/example_silc.conf.in since it is redundant.
930 The make install will now install irssi/silc.conf file.
932 * Added new Passphrase and Publickey authentication methods to
933 config file, allowing both public key and passphrase based
934 authentication to be set at the same time.
936 Added `prefer_passphrase_auth' setting in config file which
937 can be used to set to prefer passwd auth if both passwd and
938 public key is set. If not set, public key is preferred.
939 This has effect only when being initiator (responder will try
942 Added support for authentication with passphrase and public key
943 at the same time. The passphrase is tried first always since
944 it is faster to check.
946 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].

994 * Fixed the file transfer's key agreement payload to include
995 zero port also if the hostname is NULL because it could not
998 Call file transfer monitor callback now also if error occurs
999 during key agreement protocol.
1001 Changed the silc_client_file_send interface to return the
1002 SilcClientFileError instead of session id. The session ID
1003 is returned into pointer provided as argument.
1005 Check that the file exists locally before sending the
1006 file transfer request at all.
1008 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1010 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1019 SILC_LOG_WARNING to give out Warning and not Error. Affected
1020 file lib/silcutil/silclog.c.
1022 * Fixed the channel message payload decryption in the function
1023 silc_channel_message_payload_decrypt to not modify the original
1024 buffer before it is verified that the message decrypted
1025 correctly. Otherwise, next time it is called with correct
1026 channel key it won't encrypt since the payload is corrupted.
1027 Affected file lib/silccore/silcchannel.c.
1029 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1042 the table with foreach callback. The current entry may
1043 become invalid in the callback but it was referenced after
1044 the callback returned.
1046 Do not allow auto rehashing of hash table during the
1047 silc_hash_table_foreach operation, for same reasons as it is
1048 not allowed for SilcHashTableList. Affected files are
1049 lib/silcutil/silchashtable.[ch].

1067 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1068 from client library.
1070 * Added cross reference of the joined channels to the
1071 SilcClientEntry, and changed the SilcChannelEntry's
1072 users list to SilcHashTable. The affected files are
1073 lib/silcclient/idlist.[ch].
1075 * Fixed a bug in hash table tarversing. While the hash table
1076 is traversed with SilcHashTableList the table must not be
1077 rehashed. It is now guaranteed that auto rehashable tables
1078 are not rehashed while tarversing the list. Also defined that
1079 silc_hash_table_rehash must not be called while tarversing
1080 the table. Added function silc_hash_table_list_reset that must
1081 be called after the tarversing is over. The affected files are
1082 lib/silcutil/silchashtable.[ch].
1084 * Changed all hash table traversing to call the new
1085 silc_hash_table_list_reset in server and in client library.
1087 * Added function silc_client_on_channel to return the
1088 SilcChannelUser entry if the specified client entry is joined
1089 on the specified channel. This is exported to application as
1090 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1092 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1094 * Fixed founder regaining problem with JOIN command on normal
1095 server. The notify for mode change must be sent always and
1096 not only if !cmd->pending. Affected file silcd/command.c.
1098 * Fixed the WHOWAS command's reply sending to support the
1099 lists correctly. Affected file silcd/command.c.
1101 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1103 * When sending JOIN command to router for processing the
1104 sender's old command identifier was not saved back to the
1105 sender's command context, fixed now. The affected file is
1108 * Create the key in JOIN command of the router did not return
1109 the channel key, added check for this. Affected file is
1112 * Fixed a channel ID update bug in JOIN command reply. Do
1113 not directly upgrade the ID but call the function
1114 silc_idlist_replace_channel_id if the ID was changed.
1115 Affected file silcd/command_reply.c.
1117 * Fixed memory leaks from command calling if it would fail.
1118 Affected file silcd/command.c.
1120 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Applied patches from cras:
1124 Memory leak fixes around libaries, irssi window resize fix,
1125 new silclist.h and silcdlist.h, all extern inline changed to
1128 * Removed dotconf from lib/dotconf, not needed anymore.
1130 * Removed TRQ from lib/trq, not needed anymore.
1132 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1133 with server connections. Later this will be configurable
1134 in config file after new config file is done. Affected file
1137 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1139 * Fixed a crash in server related to channel announcements.
1140 Affected file silcd/server.c.
1142 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed memory leaks in silc_server_create_new_channel*
1145 functions. Affected file silcd/server.c.
1147 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1148 which ID was changed. This way the router will send the
1149 user list for the channel again, and server won't be in
1150 desync in some rare circumstances. Affected file is
1151 silcd/packet_receive.c.
1153 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1155 * Check for NULL socket pointer in the function
1156 silc_server_packet_send_to_channel_real. Affected file
1157 silcd/packet_send.c.
1159 * Fixed the BAN notify handling to correctly remove ban
1160 list. Affected file silcd/packet_receive.c.
1162 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1164 * Fixed some header addition to Toolkit distribution in
1165 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1167 * Added lib/silcclient/client_ops_example.h as an template
1168 file for application programmers to quickly start using
1169 the SilcClientOperation functions in their application.
1170 Updated the lib/silcclient/README as well to tell about this
1171 nice file made available.
1173 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1175 * Call silc_server_remove_from_channels when removing client
1176 entry when NO_SUCH_CLIENT_ID was received. Affected file
1177 is silcd/command_reply.c.
1179 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1181 * Added server & router operator statistics updating. Affected
1182 file silcd/packet_receive.c and silcd/command.c.
1184 * Fixed the SERVER_SIGNOFF notify handling on normal server
1185 not to save the history information for clients. Same was
1186 fixed earlier in remove_clients_by_server function, but not
1187 here. Affected file silcd/packet_receive.c.
1189 * Raised the default connection-retry count from 4 to 7 in
1190 server. Affected file silcd/server.h.
1192 * Cancel any possible reconnect timeouts when we start the
1193 key exchange. Affected file silcd/server.c.
1195 * Do not reconnect on connection failure when SCONNECT was
1196 given. Affected files silcd/server.[ch].
1198 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1202 * Fixed the NICK command to always give the unformatted
1203 nickname to the one giving the NICK command. If unformatted
1204 nickname is cached already it will be formatted and the
1205 local entry will always get the unformatted nickname.
1206 Affected file lib/silcclient/idlist.c.
1208 * Fixed some double frees from client library commands.
1209 Affected file is lib/silcclient/command.c.
1211 * Fixed CUMODE command in server to assure that no one can
1212 change founder's mode than the founder itself, there was a
1213 little bug. Affected file silcd/command.c.
1215 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1217 * Removed the SilcClientCommandDestructor from the client
1218 libary, it is not needed anymore. Affected files are
1219 lib/silcclient/silcapi.h, command[_reply].[ch],
1220 client_notify, idlist.c.
1222 * Fixed GETKEY command to first resolve client, and then
1223 resolve the server only if the client was not found, instead
1224 of resolving both at the same time. Affected file is
1225 lib/silcclient/command.c.
1227 * Added silc_client_start_key_exchange_cb and lookup the
1228 remote hostname and IP address before starting the key
1229 exchange with server. The affected file is
1230 lib/silcclient/client.c.
1232 * The server's public key is now saved using the IP address
1233 of the server and not the servername for the filename.
1234 The hostname public key filename is checked as an fall back
1235 method if the IP address based filename is not found.
1237 Fixed the GETKEY command to save the fetched server key
1238 in correct filename.
1240 Print the remote server's hostname now when new key is
1241 received during connection process. Affected file is
1242 irssi/src/silc/core/client_ops.c.
1244 * Return always our own public key to the client if it asks
1245 for it with GETKEY command. Affected file silcd/command.c.
1247 * Removed the use_auto_addr variable from default config
1248 file since it was in wrong section. Affected file is
1251 * Fixed TOPIC_CHANGE notification to not route it when it
1252 was sent using silc_server_send_notify_to_channel function.
1253 Affected file silcd/command.c.
1255 * Fixed silc_server_send_notify_kicked to send the kicker's
1256 Client ID also, it was missing. Affected files are
1257 silcd/command.c, silcd/packet_send.[ch].
1259 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Do not save client history information in SERVER_SIGNOFF.
1262 Fixes the bug in normal server that it does not detect
1263 the client becoming valid after the server becomes back
1264 online. Affected file silcd/server_util.c.
1266 * Added `sock_error' field into the SilcSocketConnection
1267 context. When error occurs during socket operation (read
1268 or write) the error is saved. Added also new function
1269 silc_socket_get_error to return human readable socket error
1270 message. Affected files are lib/silcutil/silcsockconn.[ch],
1271 lib/silcutil/unix/silcunixsockconn.c, and
1272 lib/silcutil/win32/silcwin32sockconn.c.
1274 * The server now prints the socket error message in the
1275 signoff for client. Affected file silcd/server.c.
1277 * Fixed the `created' channel information sending from router
1278 to server in JOIN command. Checks now whether the channel
1279 really was created or not and set it according that.
1281 Fixed the JOIN command to use the client entry's current
1282 ID during the joining procedure instead of the one it sent
1283 in the command (it is checked though), since it can change
1284 between the packet processing and command processing, and
1285 would just case unnecessary pain in the client end. Affected
1286 file silcd/command.c.
1288 * Fixed a channel key payload sending to use correct channel
1289 ID when the server was forced to change the channel's ID by
1290 router. Router sent the key payload with the old Channel ID.
1291 Affected file silcd/packet_receive.c.
1293 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1295 * Call silc_server_save_channel_key only if the key payload
1296 was provided in the JOIN command's command reply. Affected
1297 file silcd/command_reply.c.
1299 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * Fixed silc_mp_sizeinbase to return the value correctly with
1302 MPI. Affected file lib/silcmath/mp_mpi.c.
1304 * Fixed the stop_server signal to correctly stop the scheduler
1305 and gracefully stop the server when SIGTERM or SIGINT signals
1306 are received. Affected file silcd/silcd.c.
1308 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1310 * Simple handling of TERM and HUP signals. Also added some log
1311 flushing call around. Affected file is
1314 * Fixed small bugs in silclog.c. Now buffering output will take
1315 effect after 10 seconds since startup: This will ensure that
1316 no important startup messages are lost. Also output redirection
1317 will preserve original format ([Date] [Type] message).
1318 Affected file is lib/silcutil/silclog.c.
1320 * Added two options to the config file, in the logging section:
1321 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1322 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1324 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1326 * Do not print the warning about log files not being initialized
1327 more than once to avoid excess logging. Affected file is
1328 lib/silcutil/silclog.c.
1330 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1331 the SIM copying in make install in Makefile.am.pre.
1333 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1335 * Rewritten silclog APIs. Globally interesting changes follows:
1336 silc_log_set_files() changed to silc_log_set_file().
1337 silc_log_set_callbacks() changed to silc_log_set_callback().
1338 ROBOdoc documented silclog header file.
1339 SilcLogCb now returns bool to wether inihibit the default
1340 handler or not (to keep the old behaviour return always TRUE).
1341 The new APIs should also fix the problem of the
1342 silcd_error.log file that was written in the current directory.
1345 Log files streams will remain opened after silc_log_set_file()
1346 call, means less CPU usage notably on high traffic servers.
1347 File streams are now full buffered, and flushed to the disk
1348 every 5 minutes, lesses HD activity and CPU usage.
1349 Messages can be redirected, allowing admins to configure
1350 one single logfile for all server messages.
1351 the silc_log_quick global variable to activate fast-logging.
1352 Affected files lib/silcutil/silclog.[ch]
1354 * Changed some code to conform new silclog APIs. Affected
1355 files are doc/example_silcd.conf.in, silcd/server.c
1356 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1359 * Fixed a memory leak that could occur in some situations.
1360 Affected file silcd/serverconfig.c.
1362 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1364 * Added the silc_client_del_client to remove the client from
1365 all channels as well. Affected file lib/silcclient/idlist.c.
1367 * Fixed the client library to correctly remove the client
1368 from all channels when the client entry is being destroyed.
1369 Affected file lib/silcclient/client_notify.c, command.c.
1371 * Added auto-nicking support to the client library. If the
1372 applicatio now sets client->nickname it will be sent to the
1373 server after connecting by the library. This way for example
1374 SILCNICK (or IRCNICK) environment variables will have effect
1375 and always change the nickname automatically to whatever
1376 it is wanted. Affected file lib/silcclient/client.[ch].
1378 * Renamed silc_server_command_bad_chars to the
1379 silc_server_name_bad_chars and moved it to the
1380 silcd/server_util.[ch]. Added also new function
1381 silc_server_name_modify_bad to return nickname that
1382 includes bad characters as new nickname without those
1383 bad characters. This check and modify is now used in
1384 silc_server_new_client when the username is initially set
1385 as nickname, so it must be checked to be valid nickname.
1386 Affected file silcd/packet_receive.c.
1388 * The nickname length is now taken from the packet for real
1389 and not trusted to strlen() since it clearly can return
1390 wrong length for nickname including bad characters. This
1391 also applies to channel names. Affected file silcd/command.c.
1393 * Removed the lib/silcsilm/modules directory. Modules are now
1394 compiled into the lib/silcsim. Fixed the copying of the
1395 modules to follow symbolic links in Makefile.am.pre.
1397 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1399 * Fixed silc_string_regexify list creation. Fixes bugs with
1400 BAN and INVITE commands in server. The affected file is
1401 lib/silcutil/unix/silcunixutil.c.
1403 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Removed the command destructor entirely from the server's
1406 command and command reply routines. It is not needed, and
1407 its usage was buggy and caused crashes. Affected files are
1408 silcd/command[_reply].[ch].
1410 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Cancel protocol and NULL sock->protocol if timeout
1413 occurred during protocol. Affected file silcd/server.c.
1415 * Cancel protocol timeouts always before calling the final
1416 callback, to assure that after final callback is called
1417 no other state will be called for the protocol anymore.
1418 Affected file silcd/protocol.c.
1420 * Print error log if incoming connection configuration could
1421 not be found. Affected file silcd/server.c.
1423 * Fixed JOIN command to correctly save the founder mode
1424 to the client on normal SILC server, when the channel
1425 was created by the router. Affected file silcd/command.c.
1427 * Fixed LIST command (hopefully) to send correct reply
1428 packets. Affected file silcd/command.c.
1430 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * The silc_packet_receive_process now returns FALSE if the
1433 read data was invalid packet, and TRUE if it was ok.
1435 The server now checks that if unauthenticated connection
1436 sends data and its processing fails the server will close
1437 the connection since it could be a malicious flooder.
1439 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1441 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1443 * Make sure the warning about error opening a log file is
1444 printed only once and not everytime it fails (produces
1445 too much useless log). Affected file lib/silcutil/silclog.c.
1447 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1449 * Made the silc_server_daemonise() function more readable.
1450 Affected file silcd/server.c.
1452 * Pid file is now optional, the user may comment it out from
1453 the config file. Removed define SILC_SERVER_PID_FILE, we
1454 don't need a default any longer. Affected file
1455 configure.in.pre, lib/Makefile.am.pre.
1457 * Make some use of the pid file. The server now dies at startup
1458 if it detects a valid pid file on his path. The server would
1459 die anyway in this circumstance, because of the bind() failure.
1460 Affected file silcd/silcd.c.
1462 * No longer compiling lib/dotconf.
1464 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Fixed JOIN command parsing not to crash. Affected file
1467 lib/silcclient/command.c.
1469 * Fied the NICK_CHANGE notify to add the new client entry
1470 even it is resolved. This removes an <[unknown]> nick
1471 thingy bug in the client. Affected file is
1472 lib/silcclient/client_notify.c.
1474 * Do not try to allocate 0 bytes (efence does not like it)
1475 in lib/silccore/silccomand.c when encoding payload.
1477 * Do not take IRCNICK as nickname in Irssi SILC client since
1478 it is not possible to set nickname before hand connecting
1479 the server (TODO has an entry about adding auto-nicking
1482 * Changed the silc_server_command_pending to check whether
1483 there already exists an pending entry with the specified
1484 command, command identifier and pending callback. This is
1485 to fix IDENTIFY and WHOIS related crashes that may register
1486 multiple pending commands with same identifier. Affected
1487 file silcd/command.c.
1489 * Fixed the server to reconnect to the router even if it
1490 was already reconnecting and EOF was received. This to
1491 fix a possibility that the server wouldn't ever try to
1492 auto-reconnect to the router. Affected file silcd/server.c.
1494 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Fixed the server's password authentication to use the
1497 length of the locally saved password, and not the one
1498 sent in the packet. Affected file silcd/protocol.c.
1500 * Fixed same password authentication problem in the
1501 Authentication Payload handling routines in
1502 lib/silccore/silcauth.c.
1504 * Yet another password authentication problem fixed with
1505 channel password handling in silcd/command.c.
1507 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * If first character of string in silc_parse_userfqdn is '@'
1510 then do not parse it. Affected file is
1511 lib/silcutil/silcutil.c.
1513 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Fixed minor bug in IDENTIFY command reply sending, which
1516 caused various weird problems during JOIN when it was
1517 resolving names for users. Affected file silcd/command.c.
1519 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Fixed the IDENTIFY command reply sending to chech better valid
1522 clients. It was possible to send incomplete list of replies.
1523 Affected file silcd/command.c.
1525 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1527 * Added silc_client_command[s]_[un]register functions now to
1528 dynamically register the commands in client library. Removed
1529 the static table of commands. This allows the client library
1530 to call commands without causing the application to know about
1531 what commands library has called.
1533 Removed the INFO command reply kludge to detect when the command
1534 was called by library. Now library use its own command reply
1535 function for INFO command.
1537 Added function silc_client_command_call to call a command.
1538 Application can use it to call command, not access the structure
1541 Now all commands that are sent by the client library (not
1542 explicitly sent by application) use own command reply functions.
1544 Affected files around lib/silcclient/ and in
1545 irssi/src/silc/core/.
1547 * Fixed the WHOIS command reply sending to chech better valid
1548 clients. It was possible to send incomplete list of replies.
1550 Fixed the WHOIS and IDENTIFY to send the request to router
1551 if normal server did not do it and did not find any results.
1553 Affected file silcd/command.c.
1555 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Moved the internal data from SilcClient context into its
1558 own file, not accesible to application. Affected files
1559 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1560 and other files in client library.
1562 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Added doc/examples installation target in Makefile.am.pre.
1567 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1570 commands the found client entry will be removed from the
1571 cache, after notifying application about the error. Affected
1572 file lib/silcclient/command_reply.c.
1574 * Changed the /MSG to check for exact nickname user gave, and
1575 not let `nick' match `nick@host' if it is only one found. Now,
1576 user must type the exact nickname (like nick@host2) even if
1577 there are no more than one same nicks found. This is to avoid
1578 a possibility of sending nickname to wrong nickname since
1579 `nick' could match `nick@host'. Affected file is
1580 irssi/src/core/silc-servers.c.
1582 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Do not print "you are now server operator" or similar when
1585 giving /away command. Affected files are
1586 irssi/src/silc/core/client_ops.c, silc-servers.h.
1588 * Made the silc_server_command_pending_error_check to send
1589 the same command reply payload it received back to the
1590 original sender of the command. This way all arguments
1591 that was received by the server will be received by the
1592 client too. Affected file silcd/command.c.
1594 * Added the silc_idcache_add to return the created cache entry
1595 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1597 * Add global clients to expire if they are not on any channel.
1598 This is because normal server will never know if they signoff
1599 if they are not on any channel. The cache expiry will take
1600 case of these entries. This is done by normal servers only.
1601 The affected files are silcd/command_reply.c,
1602 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1604 * If server receives invalid ID notification for WHOIS or
1605 IDENTIFY and the ID exists in the lists, it is removed.
1606 Affected file silcd/command_reply.c.
1608 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1609 in client then client entry that it matches is searched and
1610 the nickname is printed on the screen for user. Affected
1611 file irssi/src/silc/core/client_ops.c.
1613 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Use cache entry expire time in the LIST command reply to
1616 purge old entries from the cache after the LIST command
1617 reply has been received. This way we don't have non-existent
1618 entries in the cache for too long. Affected file is
1619 silcd/command_reply.c.
1621 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * If we are normal server, and we've not resolved client info
1624 in WHOIS or IDENTIFY from router, and it is global client,
1625 we'll check whether it is on some channel. If it is not
1626 then we cannot be sure about its validity and will resolve it
1627 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1628 file silcd/command.c.
1630 * Search channel by name (if possible) rather than by ID
1631 in IDENTIFY command's command reply. Affected file is
1632 silcd/command_reply.c.
1634 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1636 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1637 Updated specs and implemented it. Affected file silcd/command.c,
1638 silcd/packet_send.c and silcd/packet_receive.c.
1640 * Implemented the <founder auth> payload handling in the JOIN
1641 command. If provided all conditions for channel joining
1642 except requirement to provide correct passphrase can be
1643 overrided by the channel founder. Updated the protocol specs.
1644 Affected file silcd/command.c.
1646 Added support for founder auth in JOIN command in client
1647 library. Fixed the parsing of the JOIN command now to support
1648 all options as they should be. The affected file is
1649 lib/silcclient/command.c.
1651 * Optimized the WHOIS and IDENTIFY commands to send the request
1652 to router only if it includes nicknames or other names. If
1653 they include only IDs then check the local cache first before
1654 routing. Affected file is silcd/command.c.
1656 * Added channels topic announcements. Affected file is
1657 silcd/packet_receive.c and silcd/server.c.
1659 * Fixed the silc_server_send_notify_topic_set to really destine
1660 the packet to channel. Affected file silcd/packet_send.c.
1662 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1663 library. Affected file lib/silcclient/client_notify.c.
1665 * Added UMODE announcements. Affected file silcd/server.c.
1667 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1669 * Memory leak fixes in:
1671 lib/silcutil/silcsockconn.c
1672 lib/silcske/silcske.c
1673 lib/silcske/groups.c
1675 lib/silccrypt/silcpkcs.c
1676 lib/silccore/silccommand.c
1677 lib/silccore/silcidcache.c
1682 * ROBOdoc documented the lib/silcske/groups.h file and a
1683 bit changed the interface for better.
1685 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1687 * Update the client entry context in the ID cache after
1688 nick change. Affected file lib/silcclient/command.c.
1689 Fixes the CUMODE command when regaining founder privileges,
1690 and a little WHOIS problem.
1692 * Fixed silc_net_gethostbyname to correctly call the
1693 inet_ntop. Affected file lib/silcutil/silcnet.c.
1695 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1697 * Added IPv6 support checking to the configure.in.pre, added
1698 also --enable-ipv6 option to override the check. Affected
1699 file configure.in.pre.
1701 * The silc_thread_create now calls the start function
1702 directly if threads support is not compiled in. Removes
1703 ugly #ifdef's from generic code. Affected files are
1704 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1706 * Added silc_net_gethostby[name/addr]_async to asynchronously
1707 resolve. Affected files are lib/silcutil/silcnet.[ch].
1709 * Added support for rendering IPv6 based server, client and
1710 channel IDs. Affected file lib/silcutil/silcutil.c.
1712 * Added support for creating IPv6 based server IDs. Affected
1713 file is silcd/serverid.c.
1715 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1717 * Added silc_net_gethostby[addr/name] into the
1718 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1719 routines. Added silc_net_is_ip[4/6]. Affected file is
1720 lib/silcutil/unix/silcunixnet.c. All routines that take
1721 address as argument now supports both IPv4 and IPv6 addresses.
1723 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1725 * Fixed LIST command reply sending in server. Affected file
1728 * Server now sends the kicker's client ID in the KICK notify
1729 to the kicked client. Affected file silcd/command.c.
1731 * The client library now parses the kickers client ID and
1732 UI displays it. Affected files lib/silcclient/client_notify.c
1733 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1735 * Made all payload parsing function prototypes consistent.
1736 They all take now const unsigned char * and uint32 pair as
1737 the payload data instead of SilcBuffer. Changes all around
1738 the source tree. Other unsigned char* -> const unsigned char*
1739 changes around the tree as well.
1741 * Optimized SFTP client and server packet sending not to
1742 allocate new buffer for each packet but to recycle the
1743 first allocated buffer. Affected files are
1744 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1746 * Optimized the SFTP client to use SilcList instead of
1747 SilcDList for requests, because it is faster. Affected file
1748 is lib/silcsftp/sftp_client.c.
1750 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1751 into lib/silccore/silcid.[ch].
1753 Renamed silcpayload.[ch] into silcargument.[ch].
1755 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * If client entry is deleted with active key agreement
1758 session, abort the session.
1760 The silc_client_abort_key_agreement now calls the completion
1761 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1763 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1766 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Don't use __restrict in older GCC's. Affected file is
1769 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1771 * silc_net_localhost now attempts to reverse lookup the
1772 IP/hostname. Affected file lib/silcutil/silcnet.c.
1774 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1775 command. It can be used to gain founder privileges at
1776 the same time when joining the channel.
1778 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1779 kicker's client ID as well. Updated protocol specs.
1781 Defined that the server must send SILC_COMMAND_IDENTIFY
1782 command reply with error status to client who sent
1783 private message with invalid client ID.
1785 Updated the protocol specification.
1787 * Added silc_server_send_command_reply to send any
1788 command reply. Affected file silcd/packet_send.[ch].
1790 * Added silc_id_payload_encode_data to encode ID payload
1791 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1793 * The server now send IDENTIFY command reply with error
1794 status if client ID in private message is invalid. Affected
1795 file silcd/packet_receive.c.
1797 * Save the server key file with server's IP address in
1798 the filename instead of hostname. The affected file is
1799 irssi/src/silc/core/client_ops.c.
1801 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1803 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1806 * Added libtool support for compiling shared objects in
1807 lib/silcsim. Affected file configure.in.pre and
1808 lib/silcsim/Makefile.am. Original patch by cras.
1810 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * Pid file configuration, and server's config file fixes
1813 patch by toma. Updated CREDITS file.
1815 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1817 * Fixed silc_client_channel_message to not try to decrypt
1818 the message twice if it resolved the destination client
1819 information. This could cause of dropping one channel
1820 message. Affected file lib/silcclient/client_channel.c.
1822 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1825 lib/silcclient/client.c. This function is used when the SILC
1826 Client is run under some other scheduler, or event loop or
1827 main loop. On GUI applications, for example this may be
1828 desired to used to run the client under the GUI application's
1829 main loop. Typically the GUI application would register an
1830 idle task that calls this function multiple times in a second
1831 to quickly process the SILC specific data.
1833 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1835 * Fixed silc_server_drop() for dropping the supplementary
1836 groups as well, this could cause a security hole on some
1839 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1844 * Write PID file after dropping privileges. Added -F option
1845 to run server on foreground. A patch by debolaz.
1846 Affected files silcd/server.c, silcd/silcd.c.
1848 * Fixed MOTD to return the MOTD file server name. Affected
1849 file silcd/command.c.
1851 * Added INFO command reply handling to the Irssi SILC Client.
1852 Affected file irssi/src/silc/core/client_ops.c.
1854 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed the silc_idcache_list_* routines to really support
1857 the dynamic list. Fixes a crash. Affected file is
1858 lib/silccore/silcidcache.c.
1860 * Fixed the LIST command reply to really call LIST command's
1861 pending callbacks. Affected file silcd/command_reply.c.
1863 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Update conn->local_entry->nickname after giving NICK
1866 command. Affected file lib/silcclient/command.c.
1868 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1870 * Added the [pid] option to the silcd configuration file
1872 Affected files: serverconfig.[ch] and silcd.c
1874 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Save fingerprint in WHOIS command reply in server.
1877 Affected file silcd/command_reply.c.
1879 * Fixed NICK commands pending callback registration.
1880 Affected file lib/silcclient/command.c.
1882 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Use ++server->cmd_ident when sending commands in server,
1885 instead of random number. Affected file silcd/command.c.
1887 * Fixed GETKEY command reply to call actually GETKEY pending
1888 command callbacks. Affected file silcd/command_reply.c.
1890 * A bit stricter check for nicknames. Check for same nickname
1891 in NICK command also. Affected file silcd/command.c.
1893 * Do not call INFO command everytime client ID changes, only
1894 during first connecting. Affected file lib/silcclient/client.c.
1896 * Set the new nickname only after successful command reply for
1897 NICK command is returned by server. Affected file
1898 lib/silcclient/command.c.
1900 * Remove nicknames from nicklist during server_signoff notify.
1901 Should fix /NAMES bit more. The affected file is
1902 irssi/src/silc/core/silc-channels.c.
1904 * Added `fingerprint' field to the SilcIDListData in the
1905 silcd/idlist.h to hold the fingerprint of the client's
1908 Send the fingerprint of the client's public key in WHOIS
1911 Affected files silcd/command.c, and silcd/idlist.[ch].
1913 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1914 create fingerprint from given data.
1916 * Show the fingerprint of the client's public key in WHOIS.
1917 Affected files irssi/src/module-formats.[ch] and
1918 irssi/src/silc/core/client_ops.c.
1920 * Format the multiple same nicknames also during JOIN and
1921 NICK_CHANGE notifys. Affected file is
1922 lib/silcclient/client_notify.c.
1924 * Do not print error on screen for invalid private message
1925 payload since it can come if someone is sending private
1926 messages with wrong key. Affected file
1927 lib/silccore/silcprivate.c.
1929 * Fixed multiple concurrent /PING crash. Affected file
1930 lib/silcclient/command.c.
1932 * Changed the wrong ID encoding. All IP addresses must be
1933 in MSB first order in encoded format. They were encoded
1934 wrong and was in LSB format. Affected files are
1935 silcd/serverid.c, lib/silcutil/silcutil.c.
1937 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1939 * Call the `connect' client operation through the scheduler
1940 in case of error. Affected file lib/silcclient/client.c.
1942 * Call the `failure' client operation even if the error
1943 occurred locally during a protocol. Affected file is
1944 lib/silcclient/protocol.c.
1946 * Added support of sending LIST command to router from normal
1947 server. This way normal server can get list of all channels
1948 in the network too. Fixed the channel list sending in the
1949 server too. Affected files are silcd/command.c, and
1950 silcd/command_reply.[ch].
1952 * Added silc_server_update_channels_by_server and
1953 silc_server_remove_channels_by_server. They are used during
1954 disconnection of primary router and in backup router protocol.
1955 Affected file silcd/server_util.[ch], silcd/server.c and
1956 silcd/server_backup.c.
1958 * Fixed channel adding to global list in IDENTIFY command
1959 reply in server. Affected file silcd/command_reply.c.
1961 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * If the incoming packet type is REKEY or REKEY_DONE process
1964 that packet always synchronously. Fixes yet another MAC
1965 failed error on slow (dialup) connections. Affected file
1966 lib/silcclient/client.c and silcd/server.c.
1968 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Call check_version SKE callback for initiator too. Affected
1971 file lib/silcske/silcske.c.
1973 * Implemented fix for security hole found in the SKE that was
1974 fixed in the specification few days back; the initiator's
1975 public key is now added to the HASH value computation.
1976 Added backwards support for the old way of doing it too, for
1977 old clients and old servers. Affected file is
1978 lib/silcske/silcske.c.
1980 * Enabled mutual authentication by default in SKE. If initiator
1981 is not providing mutual authentication the responder will
1982 force it. This will provide the proof of posession of the
1983 private key for responder. The affected files are
1984 lib/silcclient/protocol.c and silcd/protocol.c.
1986 * Do not cache anymore the server's public key during SKE.
1987 We do mutual authentication so the proof of posession of
1988 private key is done, and if the server is authenticated in
1989 conn auth protocol with public key we must have the public
1990 key already. Affected file silcd/protocol.c.
1992 * Added new global debug variable: silc_debug_hexdump. If
1993 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1994 file lib/silcutil/silclog.[ch].
1996 * Fixed compilation warning due to char * -> const char *.
1997 Affected files lib/silcutil/silcnet.h, and
1998 lib/silccore/silcauth.[ch].
2000 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Fixed CMODE command when new channel key was created. If
2003 the creation failed the old key was removed. Next time giving
2004 same command would crash the server since the old key was
2005 freed already. Affected file silcd/command.c.
2007 * Fixed the silc_server_announce_get_channels to not crash
2008 on reconnect. Affected file silcd/server.c.
2010 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Added silc_log_set_debug_string function to set a regex
2013 string to match for debug output. Only the function names,
2014 or filenames matching the given debug string is actually
2015 printed. This way it is possible to filter out those debug
2016 strings that user is not interested in.
2018 Fixed a bug in silc_string_regexify.
2020 Affected files lib/silcutil/silclog.[ch], and
2021 lib/silcutil/unix/silcunixutil.c.
2023 * Changed the -d options in both server and Irssi SILC client
2024 to take the debug string as argument. Affected files
2025 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2027 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Added silc_hash_babbleprint to create a Bubble Babble
2030 Encoded fingerprint. The encoding is developed by Antti
2031 Huima (draft-huima-babble-01.txt), and it creates human
2032 readable strings out of binary data. Affected file
2033 lib/silccrypt/silchash.[ch].
2035 * Print the babble print now in addition of fingerprint as well
2036 in Irssi SILC client. Affected files are
2037 irssi/src/fe-common/silc/module-formats.[ch],
2038 irssi/src/fe-common/silc/core/client_ops.c.
2040 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * Fixed a security problem found in SKE. The initiator's
2043 public key too is now added to the HASH hash value creation
2044 which is signed by the responder to create the SIGN value.
2045 This will prevent anyone in the middle to lie to the responder
2046 about the initiator's public key. If this is done now, the
2047 man in the middle will get caught. Updated the protocol
2050 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Better installation directory handling. Configure module
2053 paths and other paths automatically to example_silc* files
2054 in doc/. A patch by toma.
2056 * Fixed compiler warning from MPI library, and from SILC RNG.
2059 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2060 It can be configured with ./configure. A patch by toma.
2062 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Find correct make to use in prepare-clean. A patch by
2065 toma. Affected file prepare-clean.
2067 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2069 * Added irssi variables use_auto_addr, auto_bind_ip,
2070 auto_bind_port and auto_public_ip.
2072 * Changed the interface for silc_client_send_key_agreement
2073 in lib/silcclient/silcapi.h
2077 irssi/src/silc/core/silc-core.c
2079 lib/silcclient/silcapi.h
2080 irssi/src/silc/core/silc-channels.c
2081 lib/silcclient/client_keyagr.c
2084 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Added silc_pkcs_public_key_compare to compare two
2087 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2089 * Check that the client who set the founder mode on the
2090 channel is the same client that is giving the founder
2091 mode to itself. It is done by comparing the saved public
2092 key (it is saved even in the authentication is passphrase).
2093 Affected file silcd/command.c.
2095 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2097 * Do not process packet for disconnected socket connection.
2098 Affected file lib/silccore/silcpacket.c.
2100 * Process the DISCONNECT packet through scheduler in the
2101 client library. Affected file lib/silcclient/client.c.
2103 * Fixed the silc_client_packet_parse to not to increase
2104 the packet sequence number if the conn->sock and the
2105 current socket connection is not same. This can happen
2106 for example during key agreement when the conn includes
2107 multiple socket connections (listeners). Affected file
2108 lib/silcclient/client.c.
2110 * The sender of the file transfer request now provides also
2111 the pointer (listener) for the key exchange protocol. If
2112 the listener cannot be created then it sends empty key
2113 agreement and lets the receiver provide the listener.
2115 Added `local_ip' and `local_port' arguments to the
2116 silc_client_file_send. If they are provided they are used,
2117 if not then it will attempt to find local IP address, if
2118 not found or bind fails then the remote client will provide
2121 Affected files are lib/silcclient/client_ftp.c and
2122 lib/silcclient/silcapi.h.
2124 * Extended the FILE SEND command to support defining the
2125 local IP and port for key exchange listener. They are
2126 optional. Affected file irssi/src/silc/core/silc-servers.c.
2128 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Defined to WHOIS command reply the sending of fingerprint
2131 of the client's public key (if the proof of posession of the
2132 corresponding private key is verified by the server).
2133 Updated to the protocol specification.
2135 * Added support of receiving the client's public key's
2136 fingerprint in command reply in client library. Affected
2137 file is lib/silcclient/command_reply.c, and
2138 lib/silcclient/idlist.[ch].

2197 preserve the WHOWAS info for the client. Affected file
2198 silcd/server_util.c.
2200 * Fixed SERVER_SIGNOFF notify handling in the server. The
2201 server is now able to process incoming SERVER_SIGNOFF notify
2202 for a server that it doesn't even know about. It will remove
2203 the clients provided in the notify. Affected file
2204 silcd/packet_receive.c.
2206 * Check for partial packet in data queue after every packet that
2207 was found from the queue. Return and wait for more data if
2208 there is partial data in queue. Affected file is
2209 lib/silccore/silcpacket.c.
2211 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2226 irssi/src/fe-common/silc/module-formats.[ch].
2228 * Wrote a help file for FILE command.
2230 * Added silc_rng_global_get_byte_fast to get not-so-secure
2231 random data as fast as possible. Random data is read from
2232 /dev/urandom if available and from the SILC RNG if not
2233 available. It is used in padding generation. Affected file
2234 lib/silccrypt/silcrng.[ch].
2236 * All packets in client library are now processed synchronously.
2237 Optimized packet processing a lot. Affected file
2238 lib/silcclient/client.c.

2249 * Assure that silc_client_notify_by_server_resolve does not
2250 resolve the client information multiple times. If it cannot
2251 be found by the first it cannot be found at all. Affected
2252 file lib/silcclient/client_notify.c.
2254 * Fixed WHOWAS command reply calling. Affected file
2255 lib/silcclient/command_reply.c.
2257 * Removed all references to silc_idlist_get_client from the
2258 Irssi SILC client since that call is internal call used by
2259 the library. The Irssi SILC client will use now client
2260 retrieval functions found in silcapi.h.
2262 * Fixed a bug in resolving nickname info before sending
2263 private message. It used freed memory. Affected file
2264 irssi/src/silc/core/silc-servers.c.
2266 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Assure my_channels statistics cannot go negative in server.
2269 Affected files silcd/server.c, silcd/server_util.c.

2285 * Added silc_net_localip to return local host's IP address.
2286 Affected file lib/silcutil/silcnet.[ch].
2288 * If key exchange or rekey protocol is active for a connection
2289 parse all packets syncronously since there might be packets
2290 in packet queue that we are not able to process without first
2291 processing packets before them. Affected file silcd/server,
2292 lib/silcclient/client.c.
2294 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2295 whether library should continue processing the packet.
2296 Affected file lib/silccore/silcpacket.h.

2342 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2343 is incomplete and is being resolved, it won't be resolved
2346 Make sure also that USERS command reply does not resolve
2347 twice information. Affected file is
2348 lib/silcclient/command_reply.c.
2350 Make sure that silc_client_get_clients_by_list does not
2351 resolve twice same information.
2353 * Check for valid client->id in the silc_server_free_client_data.
2354 Affected file silcd/server.c.
2356 * Fixed /GETKEY nick@server not to crash if the server entry
2357 is not found. Affected file lib/silcclient/command.c.
2359 * Fixed the silc_server_check_cmode_rights to check the
2360 requested modes correctly. Affected file silcd/command.c.

2365 Affected file silcd/command.c.
2367 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Call the silc_server_udpate_servers_by_server in the
2370 primary router that comes back online in the backup resuming
2371 protocol. Otherwise it routes packets wrong. Affected file
2372 silcd/server_util.[ch], silcd/server_backup.c.
2374 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2377 lib/silcutil/silcbuffmt.[ch].
2379 * Redefined the SILC packet header to include the padding
2380 length. Affected file lib/silccore/silcpacket.[ch].
2382 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2383 length for maximum padding up to 128 bytes). Affected
2384 file lib/silccore/silcpacket.h.
2386 * Removed all backwards support for old 0.5.x MAC thingies.
2387 The SILC packet header change makes it impossible to be
2388 backwards compatible.
2390 * Send the ENDING packet with timeout in the backup resuming
2391 protocol. This is to assure that all routers has connected
2392 to the primary router. Affected file silcd/server_backup.c.
2394 * Changed the RNG to take the first IV from random data. It
2395 used to take it from zero actually. Changed the RNG also
2396 to use /dev/urandom during session. /dev/random is used
2397 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2399 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Changed the SILC packet header to have the first two bytes
2402 (the packet length) encrypted. Affected files aroung the
2403 code tree, lib/silccore/silcpacket.[ch]. Removed the
2404 SilcPacketCheckDecrypt callback. It is not needed anymore
2405 since the silc_packet_receive_process will determine now
2406 whether the packet is normal or special.
2408 * Implemented the unidirectional MAC keys. Affected files
2409 lib/silcske/silcske.c, silcd/protocol.c and
2410 lib/silcclient/protocol.c.
2412 * Implemented the packet sequence number to the MAC computation.
2413 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2414 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2415 lib/silcclient/protocol.c.
2417 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Allow backup router to announce servers. All servers
2420 announced by backup router are added to the global list
2421 automatically. Update hte server's socket to our primary
2422 router also when backup router announces a server.
2423 Affected file silcd/packet_receive.c.
2425 * Do not update the client->router in the function
2426 silc_server_udpate_clients_by_server if the client is on
2427 global list. We might fail to find any specific server
2428 for locally connected clients and local cell clients. They
2429 should still use the `from' and not `to' as client->router.
2430 This fixes backup router resuming protocol. Affected file
2431 silcd/server_util.c.
2433 * Decrease channel statistics count only if the channel
2434 deletion worked. Affected files are silcd/server.c and
2435 silcd/server_util.c.
2437 * Added silc_server_update_servers_by_server to update origin
2438 of all server entries. Used during backup router protocol.
2439 Affected files silcd/server_util.[ch], silcd/server.c. and
2440 silcd/backup_router.c.
2442 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2443 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2444 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2445 lib/silccrypt/silchmac.c.
2447 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Assure that router cannot reroute the same channel message
2450 to the sender. Affected file silcd/packet_receive.c.
2452 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Made better checks that the channel message is not sent
2455 to the router it came from. Affected file is
2456 silcd/packet_send.c. Fixed memory leak too.
2458 * Announce informations for incoming router connection, but
2459 only after checking if it is replaced by backup router.
2460 Affected file silcd/packet_receive.c.
2462 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Fixed the backup resuming protocol to work in multiple
2465 router environment. Affected file silcd/server_backup.c.
2467 * Route packet only to one router in the function
2468 silc_server_packet_send_to_channel. Affected file is
2469 silcd/packet_send.c.
2471 * Fixed silc_server_send_notify_dest to set the broadcast
2472 flag. Fixed the silc_server_send_notify_topic to actually
2473 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2474 Affected file silcd/packet_send.c.
2476 * Changed the SFTP Filesystem interface. Changed the
2477 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2478 the filesystem operation function. The SilcSFTPFilesystem
2479 is now a context that is allocated by all filesystem allocation
2480 functions and it already includes the operations structure
2481 and filesystem specific context. It is given as argument
2482 now to the silc_sftp_server_start. This made the interface
2483 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2484 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2486 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Changed the backup router adding and getting interfaces
2489 in the server. The router that will be replaced by the
2490 specified backup router is now sent as argument. Affected
2491 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2494 * Added silc_net_addr2bin_ne to return the binary form of
2495 the IP address in network byte order. Affected files
2496 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2498 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Check for existing server ID in silc_server_new_server
2501 and in silc_server_connect_to_router_final and remove the
2502 old entry if it exists. Affected file silcd/packet_receive.c,
2505 * Send the channel message always to only one router, either
2506 in upstream or downstream. Affected file is
2507 silcd/packet_send.c.
2509 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Wrote the definition of the backup resuming protocol to the
2512 protocol specification.
2514 * Removed one redundant channel key generation from normal
2515 server during joining procedure. Removed one redundant
2516 channel key sending from server to router during joining
2517 procedure. Affected file silcd/command.c.
2519 * Made minor bugfixes to the backup router resuming protocol.
2520 Affected file silcd/server_backup.c, server.c.
2522 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2524 * Added --disable-asm configuration option. Affected files
2525 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2528 * Implemented the backup resuming protocol that is used to
2529 resume the primary router position in the cell after the
2530 primary router comes back online. Affected files
2531 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2532 and silcd/server_util.[ch].
2534 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Sleep two (2) seconds after sending QUIT command to server.
2537 Affected file lib/silcclient/command.c.
2539 * Assure that if outgoing data buffer is pending do not force
2540 send any data. Affected file silcd/packet_send.c.
2542 * Assure that if outgoing data buffer is pending do not force
2543 send any data. Affected file lib/silcclient/client.c.
2545 * Implemented the backup router support when the primary router
2546 goes down. The servers and routers can now use the backup
2547 router as new primary router without loosing connectivity.
2549 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2552 in the server to indicate disabled entry. All data read
2553 from the connection will be ignored and no data is sent
2554 for entry that is disabled. Affected files are
2555 silcd/idlist.h, silcd/server.c.
2557 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Created SFTP client and server test programs in the
2560 lib/silcsftp/tests directory.
2562 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Implemented memory filesystem (virtual filesystem) for
2565 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2568 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Implemented the SFTP (SSH File Transfer Protocol) to the
2571 lib/silcsftp. It includes SFTP client and SFTP server
2574 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Moved lib/silccore/silcprotocol.[ch] to the
2577 lib/silcutil library.
2579 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2580 take variable argument list pointer as argument. Affected
2581 file lib/silcutil/silcbuffmt.[ch].
2583 * Added silc_buffer_set function that is used to set data
2584 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2585 Affected file lib/silcutil/silcbuffer.h.
2587 * Changed various routines in the core library to use the new
2588 silc_buffer_set instead of allocating new buffer only for
2591 * Added 64-bit value formatting and unformatting support to the
2592 silc_buffer_[un]format routines. Affected file is
2593 lib/silcutil/silcbuffmt.[ch].
2595 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2596 to includes/bitmove.h.
2598 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Fixed channel user mode saving in client library. Affected
2601 file lib/silcclient/command[_reply].c.
2603 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Defined the file transfer to the SILC Protocol. Added
2606 new packet type SILC_PACKET_FTP and defined File Transfer
2607 Payload. The mandatory file transfer protocol is SFTP
2608 (SSH File Transfer Protocol). Affected file in addition
2609 of the internet draft is lib/silccore/silcpacket.h.
2611 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2612 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2613 is used as part of backup router protocol when the primary
2614 router of the cell is back online and wishes to resume
2615 the position as primary router.
2617 * Redefined the MAC generation keys in the protocol. The
2618 same key is not used anymore in both direction. Both
2619 direction will now use different keys for sending and
2620 receiving. This fixes a potential security flaw. This
2621 change causes incompatibilities in the protocol.
2623 * Redefined also the MAC computation from the packet.
2624 An packet sequence number is now added to the MAC
2625 computation. This prevents possible replay attacks against
2626 the protocol. This change too causes incompatibilities
2629 Added `sequence' field to the SilcPacketContext to hold
2630 the current sequence number for the packet.
2632 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Added `created' field to the SilcIDListData in the file
2635 silcd/idlist.h to indicate the time when the entry was
2638 * Added `created' field to the SilcChannelEntry too. Affected
2639 file silcd/idlist.h.
2641 * Added `creation_time' aguments to all the announcement functions
2642 in the server. If it is provided then only the entries that
2643 was created after the provided time frame are actually
2644 announced. Affected file silcd/server.[ch].
2646 * The protocol says that the Channel ID's IP address must be
2647 based on the router's IP address. Added check for this in
2648 the silc_server_new_channel when processing incoming New Channel
2649 Payload. Affected file silcd/packet_receive.c.
2651 * Print out the correct version with --version in SILC client.
2652 Affected file irssi/src/silc/core/silc-core.c.
2654 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Fixed WHOWAS command to check for completnes of the client
2657 entry always, not just when the command is coming from client.
2658 Affected file silcd/command.c.
2660 * Added new function silc_server_packet_queue_purge to purge the
2661 outgoing data queue to the network. After the function returns
2662 it is guaranteed that the outgoing packet queue is empty.
2663 Affected file silcd/packet_send.[ch].
2665 * Purge the outgoing packet queue in the rekey protocol's final
2666 callback to assure that all rekey packets go to the network
2667 before quitting the protocol. Affected file silcd/server.c.
2669 * Added silc_client_packet_queue_parse as similar function as
2670 in server to the client library. The affected file is
2671 lib/silcclient/client.c.
2673 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * Splitted silcd/server.c and created silcd/server_util.[ch]
2676 for utility functions.
2678 * Added new socket flag SILC_SF_DISABLED to indicate that the
2679 connection is open but nothing can be sent to or received from
2680 the connection. Affected file lib/silcutil/silsockconn.[ch].
2681 The checking for disabled socket is checked in the low level
2682 silc_socket_write and silc_socket_read functions.
2684 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Allow only nicknames and channel names that fits into the
2687 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2689 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * When processing JOIN command reply in server check that if
2692 the channel exists in our global list we'll move it the local
2693 list. Affected file silcd/command_reply.c.
2695 * Fixed the check whether client is joined on the channel already
2696 in JOIN command. Affected file lib/silcclient/command.c.
2698 * Fixed the JOIN command reply to check whether the channel
2699 already exists. Affected file lib/silcclient/command_reply.c.
2701 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Added silc_ske_status_string to map the SKE error numbers
2704 to readable strings. The affected files are
2705 lib/silcske/silcske[_status].[ch].
2707 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Do not show the private channels on the WHOIS channel list
2710 as it is not allowed by the protocol. The affected file is
2713 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Assure that the packet length digged from the actual packet
2716 is something sensible in the silc_packet_decrypt_rest_special
2717 in lib/silccrypt/silcpacket.c.
2719 * Free and NULL the allocated pointer in silc_hmac_alloc if
2720 the HMAC allocation fails. The affected file is
2721 lib/silccrypt/silchmac.c.
2723 * Print the selected security properties to the log files in
2724 the server. Affected file silcd/protocol.c.
2726 * Add SKE's reference counter even if calling the completion
2727 callback manually. Otherwise it goes negative, although it
2728 does not cause any problems. The affected file is
2729 lib/silcske/silcske.c.
2731 * Remove the client entry with short timeout after giving the
2732 KILL command. Affected file lib/silcclient/command.c.
2734 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2735 case all found clients are already disconnected (WHOWAS would
2736 found them) in the server. Affected file silcd/command.c.
2738 * Update the last_receive (time of last data received) to be
2739 updated only when received private or channel message so that
2740 the idle time showed in WHOIS makes more sense.
2742 * Added boolean field `valid' in to the SilcClientEntry in the
2743 client library to indicate whether the entry is valid or not.
2744 This fixes the nickname change bug on channel when changing
2745 the nickname to be same than the old (like nick to Nick) the
2746 nickname formatter doesn't set the new nick anymore to Nick@host.
2747 Affected file lib/silcclient/idlist.[ch].
2749 * Now actually fixed the nickname changing on disconnection.
2750 Added new function silc_change_nick to the Irssi SILC Client.
2751 Affected file irssi/src/silc/core/client_ops.c,
2752 irssi/src/silc/core/silc-nicklist.[ch].
2754 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Check that the public key exists in the GETKEY command before
2757 trying to encode it. Affected file silcd/command.c.
2759 * Print some notifications on received public keys with GETKEY
2760 command in the Irssi SILC Client. Affected files are
2761 irssi/src/fe-common/silc/module-formats.[ch],
2762 irssi/src/silc/core/client_ops.c.
2764 * Use IDENTIFY command to resolve the server information in the
2765 GETKEY command instead of INFO command. Affected file
2766 lib/silcclient/command.c.
2768 * All command reply functions in the client library now calls
2769 the pending command reply callbacks even if an error has
2770 occurred. The server has done this a long time and now it was
2771 time to move the client library to this as well. Now all
2772 errors can be delivered back to the pending command reply
2773 callbacks if necessary. Affected files are
2774 lib/silcclient/command[_reply].[ch].
2776 * Change the nickname on disconnection back to the username
2777 because in reconnect the server will enforce it to it anyway.
2778 Affected file irssi/src/silc/core/silc-servers.c.
2780 * Fixed a config file parsing bug in the Irssi SILC client.
2781 Affected file irssi/src/silc/core/clientconfig.c.
2783 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * When printing the channel mode on JOIN, verify that the
2786 channel key and channel's HMAC are valid. Affected file
2787 irssi/src/silc/core/client_ops.c.
2789 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2792 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2793 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2795 * Removed channel key rekey task deleting from the function
2796 silc_server_save_channel_key. Affected file silcd/server.c.
2797 Added explicit timeout task context instead that is used to
2798 delete the task if we are registering a new task before the
2799 new task has elapsed.
2801 * When channel key rekey occurs the client library now saves
2802 the old channel key for a short period of time (10 seconds) and
2803 is able to use it in case some is still sending channel
2804 messages encrypted with the old key after the rekey. Affected
2805 file lib/silcclient/[idlist.h|client_channel.c].
2807 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Added check to the silc_server_new_id_real to not accept
2810 new ID if it is the sender's own ID. Affected file is
2811 silcd/packet_receive.c.
2813 * Assure that we do not announce ourself or the one we've
2814 sending our announcements when we're router and are announcing
2815 servers to our primary router. Affected file silcd/server.c.
2817 * Fixed silc_server_command_identify_check_client to assemble
2818 correct WHOIS packet. It send corrupted WHOIS packet and
2819 caused problem with router to router connections. Affected
2820 file silcd/command.c.
2822 Fixed also silc_server_command_whois_check the same way
2823 as for the IDENTIFY command.
2825 * Added new SilcIDListStatus to the server in the SilcIDListData
2826 structure. The status now includes the current status of
2827 the entry (like registered, resolved etc.). Affected file
2828 silcd/idlist.[ch]. Defined a bunch of different status types
2829 as well. This replaced the old boolean registered field as well.
2831 Added resolve_cmd_ident field to the SilcClientEntry structure
2832 too so that if the entry is for example being resolved so
2833 another command may attach to the same pending command reply
2834 without requiring to resolve the same entry again. This concept
2835 should optimize the WHOIS and the IDENTIFY resolving under
2836 heavy load by taking away unnecessary resolving for entries
2837 that are being resolved already.
2839 Added support for adding multiple pending commands for one
2840 command idenfier. Affected file silcd/command[_reply].[ch].
2842 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2843 before deleting the data. Otherwise the hash table will have
2844 freed data in comparison functions. Affected file is
2845 silcd/command_reply.c.
2847 * Fixed silc_idlist_replace_client_id to add the new entry to
2848 the cache with NULL nickname. Otherwise there will be invalid
2849 memory as the nickname after the nickname is freed. Affected
2850 file silcd/packet_receive.c.
2852 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2853 saved into wrong slots because the previous number of entries
2854 was not taken into account. Affected file silcd/idlist.c.
2855 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2857 * If we are router and we receive JOIN notify to a channel that
2858 does not have any users then notified client is marked as the
2859 channel founder, as it is it. The affected file is
2860 silcd/packet_receive.c
2862 * Added to the extended hash table API's table_del_*ext functions
2863 the destructor as argument too, so that the caller can decide
2864 which destructor to use or whether to use destructor at all.
2865 Affected file lib/silcutil/silchashtable.[ch].
2867 * Fixed ID Cache purging. It actually deleted the entries from
2868 the hash table after the data was freed. The hash table ended
2869 up comparing freed memory. The affected file is
2870 lib/silccore/silcidcache.c.
2872 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Fixed Irssi SILC client's KILL command's HELP syntax.
2876 * The USERS command now resolves the detailed user information
2877 if the userinfo field is missing. Affected file is
2878 lib/silcclient/command_reply.c.
2880 * Do not print error in silc_file_read if the read file does
2881 not exist. Just silently return NULL. Affected file is
2882 lib/silcutil/silcutil.c.
2884 * Fixed the silc_log_output to not wine about NULL filename
2885 and to not create some bogus " " filename. Affected file is
2886 lib/silcutil/silclog.c.
2888 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Fixed various printing bugs on the user interface in the
2891 Irssi SILC Client. Minor changes that were forgotten from
2894 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * Fixed the configure.in.pre and the compilation and distribution
2897 environment to support the new autoconf 2.52. That version is
2898 now required to compile the CVS trunk.
2900 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2903 to generally parse user@fqdn format strings. Affected file
2904 lib/silcutil/silcutil.c.
2906 * Added nickname_format and nickname_force_format fields to the
2907 SilcClientParams structure. The first one defines the format
2908 for the nicknames that the library will enforce if the receives
2909 multiple same nicknames. The second one is boolean value and
2910 can be used to force the library to always enforce the format
2911 to the nicknames regardles whether there are multiple nicknames
2912 or not. This configurable formatting was employed to flexibly
2913 support accessing multiple nicknames from the user interface.
2914 The userinterface can now set the nicknames to what ever format
2915 they prefer. Affected file lib/silcclient/silcapi.h.
2917 Added function silc_client_nickname_format to the file
2918 lib/silcclient/idlist.c. It performs the nickname formatting.
2920 Added new field `hostname´ to the SilcClientEntry context.
2921 It holds the hostname of the client. Affected file is
2922 lib/silcclient/idlist.h.
2924 * Irssi SILC Client sets the nicknames in nick@hostn format.
2925 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2926 irssi/src/silc/core/silc-core.c.
2928 The WHOIS printing now also shows both the real nickname and
2929 the formatted nickname so that user knows how to access the
2930 user if there are multiple same nicknames cached. Affected
2931 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2932 printing formatting too to take the hostname now as a separate
2933 argument. The Affected file is
2934 irssi/src/fe-common/silc/modules-formats.[ch].
2936 * Changed the silc_client_get_clients_local to accept the formatted
2937 nickname as argument. It accepts the real nickname too but the
2938 formatted nickname can be used to find the true entry from
2939 multiple entries. Affected file lib/silcclient/silcapi.h and
2940 lib/silcclient/idlist.c.
2942 * Added nickname_format_parse field to the SilcClientParams.
2943 It is a callback function provided by the application to parse
2944 the nickname out of the formatted nickname string. The library
2945 calls it to get the nickname from the formatted string. Since
2946 the application generally knows better the format of the nickname
2947 string it parses it instead of the library, even though library
2948 encodes the formatted string. If the callback function is not
2949 provided then the library will use the string as is. The
2950 affected file is lib/silcclient/silcapi.h.
2952 * All the nickname strings passed to the client library in
2953 commands are now expected to be formatted nickname strings.
2954 If the command does not support the formatted nickname string
2955 it will assume that the sent string is the actual nickname.
2956 Affected file lib/silcclient/command.c.
2958 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Added public key authentication support to OPER and SILCOPER
2961 commands in the client library. Affected file is
2962 lib/silcclient/command.c.
2964 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Changed the get_auth_methdod client operation to be asynchronous.
2967 It can be async if the application resolves the authentication
2968 method from the server during the negotiation. Added new
2969 SilcGetAuthMeth completion callback that the application will
2970 call after resolving the authentication method.
2972 Added function silc_client_request_authentication_method that
2973 the application can use to resolve the authentication method
2974 from the server. Added also SilcConnectionAuthRequest callback
2975 that the library will call after the server has replied. The
2976 application can call this function if it does not know the
2977 current authentication method.
2979 Affected files are lib/silcclient/client.c and
2980 lib/silcclient/silcapi.h.
2982 * The Irssi SILC client now automatically resolves the authentication
2983 method incase any configuration information is not present (and
2984 currently there never is). The affected file is
2985 irssi/src/silc/core/client_ops.c.
2987 * Fixed public key authentication from the client library.
2988 Affected file lib/silcclient/protocol.c. Changed also the
2989 protocol specification about the public key authentication in
2990 the connection authentication protocol. The actual data to be
2991 signed is now computed with a hash function before signing.
2993 * Fixed the public key authentication from the server as well.
2994 Affected file silcd/protocol.c.
2996 * Removed the mlock()'s from the memory allocation routines.
2997 Affected file lib/silcutil/silcmemory.c. The ./configure does
2998 not check anymore for the mlock(). Affected file is
3001 * Fixed USERS command in server to allow the execution of the
3002 command for private and secret channels if the client sending
3003 the command is on the channel. Affected file silcd/command.c.
3005 * Fixed silc_client_get_clients_local to return the clients
3006 count correctly. It could return wrong value. Affected file
3007 lib/silcclient/idlist.c.
3009 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3012 types. The assembler optimizations seemed not to like 64-bit
3013 data types. The assmebler optimizations thus are now enabled
3014 also for BSD systems as opposed to only enable them for Linux.
3016 * Do not check for threads at all on BSD systems. Affected
3017 file configure.in.pre.
3019 * Removed -n and -h options from the Irssi SILC Client since
3020 they are not used in silc.
3022 * Fixed the prime generation to assure that the first digit
3023 of the generated random number is not zero since our conversion
3024 routines does not like number strings that starts with zero
3025 digit. If zero digit is seen the random number is regenerated.
3026 This caused some corrupted RSA keys when the zero first digit
3027 was met. Affected file lib/silcmath/silcprimegen.c.
3029 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Fixed WIN32 configuration in the ./configure script.
3032 Fixed to include xti.h on environments that has it.
3033 Patches by Carsten Ilchmann and andrew.
3035 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Changed the silc_id_create_client_id to be collision
3038 resistant. It is now assured that there cannot be created
3039 two same client ID's. I suspect that some weird bugs in
3040 the server were actually caused by duplicate Client IDs.
3041 Affected file silcd/serverid.[ch]. A router receiving
3042 new ID now also assures and informs the sending server
3043 if the ID caused collision.
3045 * Changed the silc_id_create_channel_id to also assure that
3046 there are no collisions.
3048 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Statement about ignoring the Mutual Authentication flag when
3051 performing rekey with PFS was a bit misleading. It is ignored
3052 if it was set in the initial negotiation, it cannot be even
3053 set in the rekey. Fixed in the ke-auth draft. Started the
3054 new versions of the protocol drafts in the doc/.
3056 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3058 * Fixed a bug in silc_client_command_identify_save when saving
3059 new channel information. The channel name was no duplicated
3060 and caused crash on exit. Affected file is
3061 lib/silcclient/command_reply.c.
3063 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * Fixed the getkey command handling in the server. Send just
3066 empty OK reply to the sender if the key could not be fetched
3067 (but everything else was ok, like the key just was not available).
3068 Changed the public key parameter to optional in the protocol
3069 specs so that empty OK reply can be sent. Affected file
3072 Added a message to Irssi SILC client to tell to user if the
3073 server did not return a public key.
3075 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Fixed a channel key regeneration bug. It registered new
3078 timeout tasks exponentially until all system resources were
3079 used. Affected file silcd/server.c.
3081 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Added the SILC Document generator to the scripts/silcdoc.
3084 It can be used to generate the Toolkit Reference Manual out
3085 of the source tree. Internally it will also use the RoboDoc
3086 generator now imported in util/robodoc.
3088 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3090 * Added couple of return's in rekey protocol if error orccurred
3091 during the protocol. The execution must be terminated.
3092 Affected file silcd/protocol.c. Also, terminate the protocol
3093 always with timeout.
3095 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * The client's Client ID was created initally from the wrong
3098 nickname (it could have been in format nick@host) in the
3099 silc_server_new_client. Affected file silcd/packet_receive.c
3101 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Added some SILC_LOG_ERROR's to various error conditions
3104 if client could not be added to ID cache. Affected files
3105 silcd/packet_receive.c and silcd/server.c.
3107 * When client's sock->user_data is freed, NULL also the
3108 client->router and client->connection pointers. Added check
3109 for these pointers being NULL to various places around the
3110 code. Affected file silcd/server.c.
3112 * Added client->data.registered == TRUE checks to various
3113 places around the code to assure that unregistered client's
3114 are not handled when it is not allowed. Affected file
3117 * Added `bool registered' fields to all
3118 silc_idlist_[server|client]_get_* routines to indicate whether
3119 the fetched client needs to be registered or not. Affected
3120 file silcd/idlist.[ch].
3122 * Add your own entry as registered to the ID cache in the
3123 server. Affected file server.c.
3125 * Fixed a bug in silc_server_new_server. The SilcServer was
3126 set as the new server's context instead of SilcServerEntry.
3127 This naturally caused some weird bugs.
3129 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3131 * Do not delete the channel rekey task when adding it
3132 for in silc_server_create_channel_key.
3134 * Changed the silc_server_create_channel_key to return
3135 TRUE or FALSE to indicate the success of the channel key
3138 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Fixed MSVC++ project files and added missing files to
3141 Makefiles under win32/.
3143 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Do not add TCP_NODELAY flag if the operating system
3146 does not have it defined. Affected files are
3147 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3149 * Fixed buffer overflow from Irssi SILC Client. Affected
3150 file irssi/src/fe-common/core/themes.c.
3152 * Fixed double free in client library in the file
3153 lib/silcclient/client.c when disconnecting from server.
3155 * Applied double free patch from cras to Irssi SILC client.
3156 Affected files irssi/src/core/[modules/expandos].c
3158 * Fixed the disconnection handling to Irssi SILC Client.
3159 The application must call silc_client_close_connection
3160 in ops->connect client operation in case of failure of
3161 the connection. Affected file is
3162 irssi/src/silc/core/client_ops.c.
3164 * Do not set sock->protocol to NULL in the function
3165 silc_client_close_connection after executing the protocol's
3166 final callback since the sock might not be valid anymore.
3167 Affected file lib/silcclient/client.c.
3169 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * Do not enable SILC_THREADS if the linking with libpthread
3172 did not happen. Affected file configure.in.pre.
3174 * Added notion to protocol specification that server must
3175 verify the sent authentication payload with CMODE when
3176 setting the channel founder key. Implemented it to the
3177 server. Affected file silcd/command.c.
3179 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3181 * Added _EXTRA_DIST SILC distribution variable to the
3182 distributions file. It is used to conditionally add extra
3183 files or directories to the specific distribution. Affected
3184 files ./prepare, Makefile.am.pre and distributions.
3186 Removed the `_' from the start of the distribution names.
3189 * Added README.WIN32 for instructions to compile the Toolkit
3192 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Fixed a double free in disconnection in the server. Affected
3195 file is silcd/server.c.
3197 * Fixed the lib/silcske/groups.c to work now also with GMP
3198 MP library. The string conversion did not work when using
3199 specific base and the base is indicated in the string as well.
3201 * Created win32/ directory which now includes MSVC++ specific
3202 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3203 It will appear only in the toolkit distribution
3205 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Changed the key material distribution function in case when
3208 the hash output is too short. The data is now concatenated
3209 a bit differently than it used to. Made the change to the
3210 SKE protocol specification.
3212 * Added better GMP detection to configure.in.pre. A patch
3215 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Fixed a minor bug in SKE that might cause some problem on
3218 some platforms. Affected file lib/silcske/silcske.c.
3220 * Added the cookie checking for initiator in the SKE. It checks
3221 that the responder returns the sent cookie unmodified. The
3222 affected file is lib/silcske/silcske.c. Added new SKE
3223 error type INVALID_COOKIE that can be sent during the
3224 negotiation. Fixed some memory leaks as well.
3226 * Added the "invalid cookie" error message to Irssi SILC client's
3229 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Added `task_max' field to the SilcClientParams to indicate
3232 the maximum tasks the scheduler can handle. If set to zero,
3233 default values are used. Affected file lib/silcclient/silcapi.h.
3235 * Fixed memory leaks in silc_client_close_connection. Affected
3236 file lib/silcclient/client.c.
3238 * Added silc_client_del_client_entry to client library to free
3239 all memory of given client entry. Affected file is
3240 lib/silcclient/idlist.[ch].
3242 * Added new functions silc_client_del_channel and
3243 silc_client_del_server to delete channel and server entries.
3244 Affected file lib/silcclient/[silcapi.h/idlist.c].
3246 * Removed silc_client_del_client_by_id from silcapi.h.
3248 * Fixed the INFO command to return the server's own info
3249 correctly when querying by Server ID. Affected file is
3252 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Removed the non-blocking settings in WIN32 code in the
3255 silc_sock_[read/write] and added SleepEx instead. Affected
3256 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3257 of input data is now checked with FIONREAD and ioctlsocket.
3259 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Call silc_schedule_task_del_by_context in the
3262 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3263 Affected file lib/silccore/silcprotocol.c.
3265 * Call silc_protocol_cancel for active protocols in the
3266 silc_server_close_connection if the funtion
3267 silc_server_free_sock_user_data has not been called.
3268 Affected file silcd/server.c.
3270 * Generic tasks cannot be deleted using the del_by_fd
3271 task deleting function since generic tasks does not match
3272 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3274 * Added a notion to SILCOPER help file that the SILCOPER works
3275 only on router server, not on normal server.
3277 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3279 * Added for WIN32 support for the new scheduler as well.
3280 Affected file lib/silcutil/win32/silcwin32schedule.c.
3282 * Fixed the SHA1 implementation to work on various platforms.
3284 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3286 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3287 API. It is part of the scheduler now. Everything else is
3288 as previously but some functions has changed their names.
3289 Checkout the lib/silcutil/silcschedule.h for the interface.
3290 Updated all applications to use the new interface. Affected
3291 files are lib/silcutil/silcschedule.[ch].
3293 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3295 * Found a bug in the SKE implementation. The HASH value,
3296 specified by the protocol, was not computed correctly. The
3297 public key of the responder was not added to the computation
3298 even though it is mandatory. Affected file lib/silcske/silcske.c.
3299 This unfortunately causes incompatibilities with older
3300 clients and servers.
3302 * Added WIN32 specific network init and uninit functions:
3303 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3304 the Winsock2. Affected file lib/silcutil/silcnet.h and
3305 lib/silcutil/win32/silcwin32net.c.
3307 * Set the socket always to nonblocking mode on WIN32 after
3308 reading data or writing data. Affected file is
3309 lib/silcutil/win32/silcwin32sockconn.c.
3311 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Fixed various compilation problems under WIN32. Affected
3314 files lib/silcutil/win32/silcwin32thread.c and
3315 lib/silcutil/win32/silcwin32schedule.c.
3317 * Removed all _internal.h #includes from public header
3318 files. Internal headers must never be included from
3321 Removed also the lib/silcske/payload_internal.h file.
3323 * All include files that may be needed (public and some others
3324 included by the public headers) by application developers are
3325 now copied to the ./includes directory. It does not copy any
3326 internal headers. Affected file Makefile.defines.pre and all
3327 Makefile.am's under lib/ and subdirs.
3329 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * Do not change the ~/.silc directory's permissions automatically.
3332 Affected file irssi/src/silc/core/clientutil.c.
3334 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * Do not cancel the protocol in silc_server_close_connection
3337 it might cause recursion. Now cancelled in the function
3338 silc_server_free_sock_user_data. Affected file silcd/server.c.
3340 * Fixed the silc_server_remove_clients_by_server to regenerate
3341 the channel keys correctly finally. Added also new function
3342 silc_server_remove_clients_channels to actually do it.
3343 Affected file silcd/server.c.
3345 * Fixed the silc_server_new_channel to not crash by giving
3346 wrong router to the new channel. Affected file is
3347 silcd/packet_receive.c.
3349 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3352 which is given as argument to the silc_client_alloc now.
3353 It can be used to configure the client and set various parameters
3354 that affect the function of the client.
3356 * The USERS command in server did not check whether the channel
3357 is private or secret. Affected file silcd/command.c.
3359 * Added new argument to the USERS command in protocol specification.
3360 The USERS command now can take the channel name as argument
3361 as well. Added support for this in client and server and
3362 updated the protocol specs.
3364 * Completed the GETKEY command in client. It can be now used
3365 to fetch also servers public key not only some clients.
3366 Affected files lib/silcclient/command[_reply].c.
3368 * Added silc_client_get_server to return server entry by the
3369 server name. Affected files lib/silcclient/silcapi.h and
3372 * Redefined the IDENTIFY command in protocol specification to be
3373 more generic. It now can be used to query information about
3374 any entity in the SILC Network, including clients, servers and
3375 channels. The query may be based either the entity's name
3376 or the ID. Added support for this in both client and server.
3378 Affected files silcd/command.c and lib/silcclient/command.c
3379 and command_reply.c.
3381 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3382 the _from_client and _from_server functions. Affected file
3385 * Added silc_client_get_channel_by_id_resolve to the file
3386 lib/silcclient/silcapi.h to resolve channel information by
3387 its ID. Added also silc_client_get_channel_by_id that
3388 does not resolve it from the server.
3390 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3392 * Added SilcServerEntry context into the client library
3393 to represent one server. The INFO command now allocates
3394 these to save the resolved server info. For now on the
3395 client library will also keep information about servers,
3396 connected and resolved with INFO.
3398 The INFO command now allocates the SilcServerEntry context
3399 and saves the server info there. The COMMAND_REPLY in
3400 the INFO now returns the parameters to application in
3401 same order as defined in the protocol specification.
3403 The entries are cached in the client->server_cache.
3405 * The INFO command is now issued after received the Client ID
3406 from the server. Affected file lib/silcclient/client.c.
3408 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3409 to the application as the mode changer might be server.
3410 It is guaranteed that NULL is not returned anymore to the
3411 application. Affected file lib/silcclient/client_notify.c.
3413 The ID Type is now also passed to the application so that
3414 it can check whether the returned entry is SilcClientEntry
3417 Added new function silc_client_get_server_by_id to return
3418 the server entry by ID. Affected files are the
3419 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3421 * Do not create the channel in the Irssi SILC Client when issuing
3422 the JOIN command but when received the sucessful JOIN command
3423 reply. Otherwise the channel might get created even though we
3424 could not join it. The Affected file is
3425 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3427 * Fixed a channel joining bug in router. The router must also
3428 check the channel modes, invite and ban lists etc. when serving
3429 the JOIN command sent by normal server. Affected file is
3430 silcd/command.c. The router now resolves the client's
3431 information from the server who sent the JOIN command if it
3432 does not know it, and processes the JOIN command only after
3435 * Changed the SilcCommandCb to take new argument; void *context2.
3436 Affected file lib/silccore/silccommand.h
3438 The second argument in the command callbacks in the server now
3439 includes the SilcServerCommandReplyContext if the command was
3440 called as pending command callback from the command reply.
3441 Otherwise it is NULL. When called as pending the status of the
3442 command reply will be checked and if it was erronous the
3443 error will be sent to the original sender of the command.
3444 This way the client always receives the error messages even
3445 though the server was actually the one who received the error
3446 when it resent the command to router, for example. Affected
3447 files silcd/command[_reply].[ch].
3449 * Fixed sending WHOWAS command's error message to client if
3450 the requested client could not be found. It was missing.
3453 * Changed the CMODE and CUMODE commands reply arguments in the
3454 protocol specification. The Channel ID is now sent in both
3455 of the commands to identify the channel. Implemented this
3456 new feature to the client and server. Affected files
3457 lib/silcclient/command_reply.c and silcd/command.c.
3459 * Made better checks for invite and ban lists in the JOIN
3460 command in server. Affected file silcd/command.c.
3462 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * The server now performs the incoming host IP/DNS lookup
3465 using the silc_socket_host_lookup and thus does not block
3466 the server anymore. Affected file silcd/server.c.
3468 * Completed the multi-thread support for SILC Scheduler in
3469 the lib/silcutil/silcschedule.c.
3471 * Fixed the configure.in.pre to detect the pthread correctly
3474 * Fixed a deadlock in silc_task_queue_wakeup in the file
3475 lib/silcutil/silctask.c.
3477 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3479 * Added new function silc_schedule_wakeup that is used in
3480 multi-threaded environment to wakeup the main thread's
3481 schduler. It needs to be used when a thread adds a new task
3482 or removes a task from task queues. After waking up, the
3483 scheduler will detect the task queue changes. If threads
3484 support is not compiled in this function has no effect.
3485 Implemented the wakeup mechanism to both Unix and WIN32
3486 systems. Affected files are lib/silcutil/silcschedule.[ch],
3487 lib/silcutil/unix/silcunixschedule.c and the
3488 lib/silcutil/win32/silcwin32schedule.c.
3490 * Added new function silc_task_queue_wakeup to wakeup the
3491 scheduler by the specified task queue. Affected file
3492 lib/silcutil/silctask.[ch].
3494 * The silc_socket_host_lookup_start now wakes up the scheduler
3495 after adding the timeout task. Affected file is
3496 lib/silcutil/silcsockconn.c.
3498 * The silc_socket_host_lookup is synchronous now if the threads
3499 support is not compiled in. However, the callback is still
3500 called asyncronously through the scheduler, anyway. Affected
3501 file lib/silcutil/silcsockconn.c.
3503 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Added new function silc_socket_host_lookup to perform
3506 asynchronous IP and FQDN lookups for the socket connection.
3507 Affected files lib/silcutil/silcsockconn.[ch].
3509 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3511 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3512 that may or may not compile the mutex support in.
3514 Changed the silc_mutex_alloc interface. It allocates the
3515 mutex now to the sent pointer and returns TRUE or FALSE.
3517 Affected file lib/silcutil/silcmutex.h.
3519 * Wrote the SILC Task Queue interface to support multi-threads.
3520 Affected file lib/silcutil/silctask.[ch].
3522 * Wrote the SILC Scheduler to support multi-threads. Affected
3523 file lib/silcutil/silcschedule.c.
3525 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3528 in lib/silcutil/win32/.
3530 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Defined SILC Mutex API and SILC Thread API and implemented
3533 them for Unix. Affected files are
3534 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3535 lib/silcutil/unix/silcunixmutex.c and
3536 lib/silcutil/unix/silcunixthread.c.
3538 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Fixed the silc_server_remove_clients_by_server's channel
3541 key re-generation. The hash table handling was incorrect
3542 and would not work with many channels. Affected file is
3545 * Fixed some memory leaks around the server code.
3547 * Rewrote the silc_server_get_users_on_channel to support IPv6
3548 based Client ID's. Affected file silcd/server.c.
3550 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3551 specification. However, a separate document must be written
3552 to define the detailed signing procedure and the payload
3553 associated with the flag. Defined the flag to the
3554 lib/silccore/silcchannel.h as well.
3556 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3558 * Changed the dynamic tables to static size tables in the
3559 lib/silccrypt/silchmac.c.
3561 * Removed GCC dependencies from the code. A patch by cras.
3563 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Do not show the error "Error receiving packet bla bla"
3566 in server if it really was not an error (-2 means that reading
3567 is pending). Affected file silcd/server.c.
3569 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Fixed a possible crash in silc_server_remove_clients_by_server
3572 in silcd/server.c. Fixed there also some memory leaks.
3574 * Fixed the silc_idlist_replace_client_id. It could replace
3575 wrong key in the hash table. Affected file silcd/idlist.c.
3577 * Do not check whether there are global users on the channel
3578 if the channel->global_users is FALSE. Affected functions
3579 silc_server_remove_from_one_channel and
3580 silc_server_remove_from_channels in silcd/server.c. Also,
3581 do not check if the removed client is local as we can be
3582 sure that global client was not removed from the channel
3583 and checking for global users is not needed.
3585 * The silc_server_remove_clients_by_server now re-generates
3586 the channel keys correctly for those channels that had
3587 clients removed from them. Affected file silcd/server.c.
3589 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3591 * Found the reason of random crashes in the server. We weren't
3592 ignoring the SIGPIPE signal (which can be sent in write())
3593 and it crashed the server. Affected file silcd/silcd.c.
3595 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Assure that sock->user_data is not NULL in the function
3598 silc_server_packet_send in silcd/packet_send.c.
3600 * Disconnect the remote connection if it could not be added
3601 to any ID lists in the server. The affected file is
3604 * Check in silc_server_packet_send[_real/dest] that the
3605 socket is not disconnecting and ignore the data if it is.
3606 Affected file silcd/packet_send.c.
3608 * Define inline to __inline on native WIN32 compilation.
3609 Affected file includes/silcwin32.h.
3611 * Added some explicit type casts for inline code since MSVC
3612 require them. Affected files lib/silcutil/silcbuffer.h,
3613 lib/trq/silcdlist.h and lib/trq/silclist.h.
3615 * Print warning in log files from now on if the packet
3616 decryption fails. Affected file silcd/server.c.
3618 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3620 * Changed the `say' client operation's interface to accept
3621 new `type' argument to indicate the type of the message sent
3622 by the library. The application may filter the library's
3623 messages according the type. The affected file is the
3624 lib/silcclient/silcapi.h.
3626 * Added two new functions to lib/silcclient/silcapi.h:
3627 silc_client_del_client and silc_client_del_client_by_id.
3628 Affected file lib/silcclient/idlist.c.
3630 * Moved the clientincludes.h from includes/ to silc/ and
3631 serverincludes.h from includes/ to silcd/.
3633 * The modes for the CMODE and CUMODE are now passed as
3634 uint32 for application with COMMAND_REPLY. The affected
3635 file is lib/silcclient/command_reply.c.
3637 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * /WHOIS without arguments shows client's own information.
3640 Affected file lib/silcclient/command.c.
3642 * Changed PING to not accept any arguments. The specs
3643 says that client can ping only the connected server so
3644 requiring an argument is not needed. Affected file is
3645 lib/silcclient/command.c.
3647 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3649 * Fixed a fatal bug in private message sending and reception
3650 encryption and decryption when using private message keys.
3651 The implementation was incorrect and did not follow the
3652 specification. It causd that some of the message were
3653 lost since it did not use the sending and receiving keys
3654 as the protocol suggests. This has been fixed and will cause
3655 incompatibilities with older clients when sending private
3656 message encrypted with private message keys. Affected files
3657 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3658 and various other in Irssi SILC Client.
3660 Added `responder' boolean argument to the functions
3661 silc_client_add_private_message_key[_ske] to indicate when
3662 the key is added as responder or initiator of the key
3665 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Removed the silc_ske_check_version function and created
3668 a SilcSKECheckVersion callback. Added also a function
3669 silc_ske_set_callbacks that is now used to set all SKE
3670 callbacks. The callback functions are not given to
3671 the SKE functions anymore, but this function is used to
3674 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3676 * Added `silc_version' argument to the silc_client_alloc
3677 to define the version of the application for the library.
3678 The library will use the version string to compare it
3679 against the remote host's (usually a server) version
3680 string. Affected file lib/silcclient/silcapi.h
3682 * Added the KE protocol context to Key Agreement context
3683 in client library so that we can abort the SKE if it
3684 is in process when we get timeout. Affected file is
3685 lib/silcclient/client_keyagr.c.
3687 * Do not resolve the client ID forever if it returns in the
3688 first time that such client does not exist. This was done
3689 for example with private message. Affected file is
3690 lib/silcclient/client_prvmsg.c.
3692 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3694 * Do not add regex.h for WIN32. The affected file
3695 includes/silcincludes.h.
3697 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3698 not work yet 100%. It generates the DLL's automatically
3699 when compiling with --with-win32 under cygwin.
3701 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3703 * lib/contrib/regex.c is not compiled on WIN32.
3705 * Added silc_net_get_socket_opt function to the
3706 lib/silcutil/silcnet.h.
3708 * Added includes/silcwin32.h for WIN32 specific includes
3711 * Do not use ptime structure or any of the posix process
3712 functions on WIN32 in lib/silccrypt/silrng.c.
3714 * Added silc_gettimeofday to provide generic function
3715 for struct timeval on all platforms. Added the function
3716 to lib/silcutil/silcutil.h.
3718 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3721 library as they clearly belong there. As a plus side we
3722 can make the actual socket connection routines platform
3725 Added also new generic function silc_socket_read and
3726 silc_socket_write (that used to be silc_packet_[read/write].
3727 The implementation of these are platform specific.
3729 * Added WIN32 specific routines of silc_socket_[read/write]
3730 to lib/silcutil/win32/silcwin32sockconn.c.
3732 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3734 * Added preliminary support for native WIN32 compilation under
3735 cygwin (using the -mno-cygwin option for GCC) to the
3736 ./configure.in.pre. The --with-win32 now prepares the
3737 compilation for native WIN32.
3739 * Rewrote the SILC Scheduler interface in the file
3740 lib/silcutil/silcschedule.h. The scheduler is now context
3741 based and does not have anymore any global static scheduler.
3742 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3743 and created lib/silcutil/win32 directory for WIN32 based
3746 * Added Unix specific network routines to the
3747 lib/silcutil/unix/silcunixnet.c and the old
3748 lib/silcutil/silcnet.c includes now only generic routines.
3750 Added WIN32 specific network routines to the
3751 lib/silcutil/win32/silcwin32net.c.
3753 * Added Unix specific utility functions from the
3754 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3756 * Added WIN32 SILC Scheduler to the file
3757 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3760 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3762 * Do not handle JOIN notify in the server if the target client
3763 is not registered (idata->registered == FALSE). The affected
3764 file is silcd/packet_receive.c.
3766 * Update the nickrec->founder in event_cumode in the Irssi SILC
3767 client. Affected file irssi/src/silc/core/silc-channels.c.
3769 * Fixed the CUMODE_CHANGE notify handling in the server when
3770 server and router are announcing their clients on channels.
3771 Now the mode changes are saved and notified correctly. The
3772 affected file is /silcd/packet_receive.c.
3774 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3775 They really did not replace the cache entry in the ID Cache.
3776 Now they do that. Affected file silcd/idlist.c.
3778 * Fixed the KICK notify handling in the Irssi SILC client to
3779 update the channel records so that the kicked client does not
3780 appear to be on the channel. The affected file is
3781 irssi/src/silc/core/silc-channels.c.
3783 * Always update the conn->current_channel when executing command
3784 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3786 * Fixed the KILL notify handling in Irssi SILC client to remove
3787 the killed client on all channels.
3789 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Fixed the silc_parse_command_line to remove extra spaces
3792 from the start and end of the arguments. Affected file is
3793 lib/silcutil/silcutil.c.
3795 * Cancel and free any active protocol in the function
3796 silc_server_close_connection. Affected file silcd/server.c.
3798 * Cancel and free any active protocol in the function
3799 silc_client_close_connction. Affected file is
3800 lib/silcclient/client.c.
3802 * Do not execute the KILL command for clients that are in
3803 history (ie. they are not in the network). Affected file is
3806 * Fixed KILL notify handling, client does not crash anymore.
3807 Affected file irssi/src/silc/core/silc-channels.c.
3809 * Reduced the default packet buffer size from 2048 to 1024 in
3810 lib/silccore/silcpacket.c.
3812 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3813 counter to the SKE context that is incresed when the SKE library
3814 performs async operation outside the library. If the outside
3815 process frees the SKE context and FREED status will be set
3816 and the library will detect after the sync operation that the
3817 libary is freed. The affected files are
3818 lib/silcske/silcske[_status].[ch].
3820 * Resolve the client entry information in the function
3821 silc_client_channel_message to assure that NULL pointer is not
3822 passed as client entry to the application. */
3824 * Fixed the task timeout calculation to assure that there is
3825 never negative timeouts. The affected file is
3826 lib/silcutil/silcschedule.c.
3828 * Fixed the channel user mode notification sending in server.
3829 It was sent point-to-point to the router (or to server by router)
3830 but it needs to be destined to a channel. The routines now
3831 supports sending the channel user mode notifys to the channels
3832 when announcing clients and channels. Affected files are
3833 silcd/server.c and silcd/packet_receive.c.
3835 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3836 It did not actually replace the old channel entry in the cache.
3837 Affected file lib/silcclient/client_notify.c.
3839 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Fixed a possible crash in silc_packet_send_prepare. It now
3842 assures always that there is enough space in the buffer and
3843 at the tail area of the buffer (for MAC).
3845 Fixed the inbound buffer reallocation in silc_packet_read.
3846 It was old code and did not handle the reallocation correctly.
3849 The affected file is lib/silccore/silcpacket.c.
3851 * Fixed buffer overflow in silc_parse_nickname in the file
3852 lib/silcutil/silcutil.c.
3854 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * make install generates new server keys only if there is not
3859 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3862 Added check that if the NOREPLY is set then we will not send
3863 the away message. This avoids infinite loop of away messages
3864 if both clients are away. The affected file is
3865 lib/silcclient/client_prvmsg.c.
3867 * Fixed client crash if /NICK was given without arguments.
3868 Affected file lib/silcclient/command.c.
3870 * Server does not send the invite list in INVITE command back
3871 to the client if the list was not altered. Added this notion
3872 to the protocol spec as well. Affected file silcd/command.c.
3874 Fixed possible crash in INVITE command by checking the
3875 value of silc_server_get_client_route command.
3877 * Fixed the INVITE notify type handling. The arguments are now
3878 taken in correct order and client does not crash. The affected
3879 file is irssi/src/silc/core/silc-channels.c.
3881 Removed the "Inviting xxx to channel" message from the
3882 client library away and let the application handle it.
3883 Affected file lib/silcclient/command.c. Added that message
3884 to Irssi SILC client's message formats.
3886 * Fixed CMODE command crash in client. It now checks the
3887 amount of arguments correctly and does not crash. The affected
3888 file is lib/silcclient/command.c.
3890 * Do not create new channel automatically in silc_channels_join
3891 but check whether the channel by that name already exists.
3892 Affected file irssi/silc/core/silc-channels.c.
3894 * Do not send the SERVER_SIGNOFF to router if the disconnected
3895 entity was the router. Affected file silcd/server.c.
3897 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3898 SILC client as it was missing from there.
3900 Added the handling of the KICK notify to the Irssi SILC client
3901 as it was missing. Added "you have been kicked" message to
3902 Irssi SILC client's message modules formats.
3904 Added the handing of the KILL notify to the Irssi SILC client
3905 as it was missing. Added the kill message module formats
3908 The affected file is irssi/src/silc/core/silc-channels.c.
3910 * The router did not save the channel mode the server announced.
3911 Affected file silcd/packet_receive.c.
3913 * Fixed a possible crash in INFO command in server. If the
3914 server did not provide the server info it crashed. Affected
3915 file silcd/command.c.
3917 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Fixed the GETKEY command in the server to check also the
3920 global list. Otherwise the GETKEY would not work correctly
3921 in normal SILC server. Affected file silcd/command.c.
3923 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Fixed GETKEY crash, it crashed if the command did not succseed.
3927 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3930 is now real and not just an macro interface to GMP.
3932 Removed the entire GMP from the source tree and imported new
3933 NSS MPI library instead. Reason for removing GMP is that it is
3934 extremely large and compiles extremely slow. The NSS MPI
3935 is only a few files and compiles in less than 10 seconds.
3936 The speed is also about the same as GMP. The MPI is imported
3937 to lib/silcmath/mpi.
3939 If the system has GMP installed we will still use the GMP.
3940 If it is not then the NSS MPI will be compiled.
3942 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Merged a long nickname (127 characters long) crash bugfix from
3945 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3947 * Merged a freed memory reference bugfix from Irssi CVS tree.
3948 Affected file irssi/src/core/commands.c.
3950 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Added the server's public key sving and verification to the
3953 server when performing the SKE. This was missing and the
3954 remote server's (or router's) public key was accepted without
3955 checking whether we have it previously or trust it at all.
3956 Affected file silcd/protocol.c.
3958 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Check in the silc_server_timeout_remote if protocol is active
3961 and make sure that the protocol's final callback is called so
3962 that all memory if freed. Affected file silcd/server.c.
3964 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * silc_server_whois_send_reply crashed the server if the nickname
3967 was 127 characters long. Affected file silcd/command.c.
3969 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added sanity check to the silc_server_new_client. If the hostname
3972 is provided inside username then check that the provided hostname
3973 really is the same as the resolved one. If the hostname was not
3974 resolved then check it from the public key. Affected file is
3975 silcd/packet_receive.c.
3977 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3978 if the server disconnected us and the connection is not valid
3979 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3981 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3982 the library to the lib/silcutil/silcutil.[ch].
3984 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Close log file after open. Affected file
3987 lib/silcutil/silclog.c.
3989 * Check whether sock == NULL in silc_client_send_packet and return
3990 if it is. Affected file lib/silcclient/silcclient.c.
3992 * Check rec->entry == NULL in the Irssi SILC Client before
3993 sending the channel message. Affecte file is
3994 irssi/src/silc/core/silc-servers.c.
3996 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Merged a splitted window bugfix from Irssi CVS tree. The
3999 affected file is irssi/src/fe-text/textbuffer-view.c.
4001 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4002 It did not print nickname.
4004 * Improved the distributions system a bit.
4006 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4009 irssi/src/fe-text/gui-window.c.
4011 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4012 to in-active server. The affected file is
4013 irssi/src/silc/core/client_ops.c.
4015 * Resolve the client in USERS command reply if the entry does
4016 not have username resolved. The affected file is
4017 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4018 command to WHOIS command to really resolve stuff. The USERS
4019 is not used any more in any critical section so WHOIS can
4020 be used even though it might be slower than IDENTIFY.
4022 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4025 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Changed the protocol API a bit more consistent in the
4028 lib/silccore/silcprotocol.[ch].
4030 * Changed the following headers to ROBODoc format:
4032 lib/silccore/silcpayload.h
4033 lib/silccore/silcprotocol.h
4034 lib/silccore/silcsockconn.h
4036 All core library headers are now formatted.
4038 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Fixed a bug in Irssi SILC client; do not show that you are
4041 server/router operator if you really are not. Affected file is
4042 irssi/src/silc/core/client_ops.c.
4044 * Renamed silc_command_free_payload to silc_command_payload_free.
4045 Affected file lib/silccore/silccommand.h
4047 * Added silcmath.h to include the prototoypes of various routines
4048 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4051 * Changed the following headers to ROBODoc format:
4053 lib/silccore/silcchannel.h
4054 lib/silccore/silccommand.h
4055 lib/silccore/silcid.h
4056 lib/silccore/silcidcache.h
4057 lib/silccore/silcmode.h
4058 lib/silccore/silcnotify.h
4059 lib/silccore/silcpacket.h
4060 lib/silcmath/silcmath.h
4062 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Added checking to the server code not to start the server if
4065 ciphers and stuff are not configured properly. Affected files
4066 silcd/serverconfig.[h] and silcd/server.c.
4068 * Changed the layout of the header files of the public interfaces
4069 in the SILC libraries. The new layout supports ROBODoc
4070 documentation tool (and some others) so that it is easy to create
4071 a library reference manual. All the other headers and source
4072 code must still follow the CodingStyle document. Also source
4073 code must not include these ROBODoc stuffs, only the headers.
4074 Furthermore, all public interface headers must now be named
4075 by using `silc' prefix, example: silcapi.h, silccipher.h.
4076 Some files were renamed due to this. All the other headers
4077 must not be used as public interfaces. I will update the
4078 CodingStyle document later. Changed following headers, so far:
4080 lib/silcclient/silcapi.h
4081 lib/silccore/silcauth.h
4082 lib/silccore/silcprivate.h
4083 lib/silccrypt/silcdh.h
4085 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Removed silc_client_packet_send_flush from the client library
4090 as it is not needed. Affected file lib/silcclient/client.[ch].
4092 * Added printing of message of unresolved authentication method
4093 to the Irssi SILC client. Added it to the module formats.
4094 Removed the same message from the client library.
4096 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Added new distribution feature, DISTLABEL. Every distribution
4099 can define own preprocessor label that can be used in the
4100 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4101 file distributions, acconfig.h.pre and prepare.
4103 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Added Makefile.defines_int to include the actual definitions
4106 for Makefile.defines.in. Tested the new distribution system,
4107 created distributions and tested installation.
4109 * Added AWAY message printing to the Irssi SILC client. Added
4110 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4112 * Added SCONNECT command to call the SILC's CONNECT command.
4113 Cannot use CONNECT directly since Irssi uses that internally.
4114 Affected file irssi/src/silc/core/silc-servers.c.
4116 Added ACTION local command. It is same as ME command but takes
4117 the channel as mandatory argument.
4119 Rewrote some of the Irssi's help files to suite for SILC
4122 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Added Makefile.defines[.in] that should for now on be included
4125 in all Makefile.am file in the source tree. That file includes
4126 all common compilation definitions for SILC source tree.
4128 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Minor changes to the ./prepare script to change the package
4131 name according the distribution name to the configure.in.
4133 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Created new distribution system. Added file `distributions'
4136 that defines all the distributions that can be created out of
4137 the SILC source tree. The ./prepare script now reads that
4138 file to determine how to prepare the distributions. The
4139 first argument to the ./prepare is the name of the distribution
4140 and second is the version of the distribution. If given
4141 without arguments it creates the default (toolkit) distribution
4142 with the default version (defined in ./prepare).
4144 All Makefile.am files that are subject to the distributions
4145 are now named as Makefile.am.pre. These are ./Makefile.am
4146 and lib/Makefile.am. Others may be changed later.
4148 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Added invite list, ban list, some key management and connection
4151 error message printing to module formats in the Irssi SILC client.
4153 * Added new silc_client_set_away_message to set the away message
4154 that is back to the person who sent private message. The
4155 affected file lib/silcclient/silcapi.h and the
4156 lib/silcclient/client_prvmsg.c.
4158 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Fixed the private message sending in the Irssi SILC client,
4161 added local command KEY to the Irssi SILC client.
4163 Added key management and key agreement message formats to the
4164 irssi/src/fe-common/silc/module-formats.[ch].
4166 Added USERS (alias WHO) printing, server/router operator
4167 indication and LIST command printing to the module formats.
4169 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Fixed channel joining notify handling, cumode notify handling
4172 from Irssi SILC client.
4174 * Added SILC specific module-formats to the Irssi SILC client so
4175 that SILC specific message hilighting, colors etc is possible.
4176 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4178 Added channel mode, channel user mode, actions, notices,
4179 whois and whowas printing to the the module-formats.c.
4181 * Fixed a bug in channel deletion in the server. The channel
4182 is not left to the cache even if the channel founder auth mode
4183 is set when there are no users anymore on the channel. Affected
4184 file silcd/server.c.
4186 * The silc_net_localhost now resolves the entire hostname including
4187 the domain name. Affected file lib/silcutil/silcnet.c.
4189 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Changed the ask_passphrase client operation to be ascynchronous.
4192 It has now a completion callback and a context that the
4193 application must call after it has got the passphrase from
4194 the user. Affected files lib/silcclient/silcapi.h,
4195 lib/silcclient/protocol.c, lib/silcclient/command.c and
4198 Added SilcAskPassphrase callback that the application calls
4199 to deliver the passphrase to the library.
4201 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4202 The public key verification and especially a certificate
4203 verification is asynchronous procedure.
4205 Added new SILC_SKE_STATUS_PENDING status to indicate the
4206 request is pending and a callback will be called to finalize
4209 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4210 indicate that remote end did not send its public key (or
4211 certificate), even though we require it. Added check for this
4212 condition in the SKE. This was a security bug, now fixed.
4214 Defined new SilcSKEVerifyCbCompletion callback that is called
4215 when the verification process is completed.
4217 The affected files lib/silcske/silcske_status.h and
4218 lib/silcske/silcske.[ch].
4220 * Changed the verify_public_key client operation to be async
4221 as well. Defined SilcVerifyPublicKey callback that is used to
4222 indicate the success of the public key verification process.
4224 Changed the server and client to use the new async client
4227 * Changed the Irssi SILC client's internal scheduler to be called
4228 twice as many times as it used to be. As a result the client
4229 should be a bit faster now. Affected file is
4230 irssi/src/silc/core/silc-core.c.
4232 * Added support to Irssi SILC client of asynchronous public key
4233 verification and passphrase inquiry. Affected file is
4234 irssi/src/silc/core/silc-core.c.
4236 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Do not say "You have left channel %s" in client library.
4239 Moved it to the application. Affected files are
4240 lib/silcclient/command.c and silc/client_ops.c.
4242 * Fixed silc_client_get_clients. Command context was not
4243 duplicated and was freed memory in the callback. Affected
4244 file lib/silcclient/idlist.c.
4246 * Do not say "you are now talking..." on JOIN command in the
4247 client library. The appliation must handle it.
4249 * Do not say ".. changed topic to" in command reply in the
4250 client libary. The application must handle it.
4252 * Fixed TOPIC command sending in the client library.
4254 * Fixed a memory leak in silc_client_command_free in the file
4255 lib/silcclient/command.c.
4257 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Imported a modified version of Irssi client to the source tree.
4260 The Irssi will be used to create a new client called
4261 Irssi SILC. Imported to irssi/.
4263 Added silc_core_init_finish function to the Irssi. Affected
4264 file irssi/configure.in.
4266 A lot changes in the Makefile.ams around the irssi tree.
4268 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Do not rehash if the new size is same as the old size of the
4271 hash table, in the silc_hash_table_rehash*. The affected file
4272 lib/silcutil/silchashtable.c.
4274 * Replaced hash_table_del_by_context calls from the server
4275 (when channel->user_list and client->channels) to the
4276 hash_table_del as it is sufficient and faster.
4278 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Added silc_hash_table_list, silc_hash_table_get and the
4281 SilcHashTableList structure to provide an alternative way to
4282 traverse the hash table. The affected files are
4283 lib/silcutil/silchashtable.[ch].
4285 * Changed the server's idlist routines to use the hash table
4286 routines to optimize the code.
4288 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Replaced the client entry's `channel' list and channel entry's
4291 `user_list' list to hash tables for optimized lookup. Changed
4292 the code to use the hash table interface around the code.
4293 Affected file lib/silcd/idlist.[ch].
4295 * Added `auto_rehash' boolean argument to the function
4296 silc_hash_table_alloc to indicate whether the hash table should
4297 auto-rehash when it thinks is appropriate time. It will
4298 increase the hash table size if the there is twice as much
4299 entries in the table than the size of the table, and will
4300 decrease the size if there are twice as less entries than
4301 the size of the table.
4303 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4307 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * silc_idcache_purge_by_context deletes the entry now by context
4310 as it is supposed to do. Affected file lib/silccore/idcache.c.
4312 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4313 client is not anymore valid (WHOWAS givens the info) and not
4314 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4316 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Removed the `data' and `data_len' arguments from the ID Cache
4319 interfaces and added `name' argument. ID Cache does not handle
4320 anymore the binary data only a names associated with given ID.
4322 * When hashing a Client ID with silc_hash_id the entire ID is
4323 not hashed anymore, instead only the hash of the Client ID is
4324 hashed. This way we can access the Client ID from the cache
4325 with Client ID but with the hash of the ID (which is a hash of
4326 the nickname) as well without any difference in performance.
4328 Added also silc_idcache_find_by_id_one_ext to do one on one
4329 searching when we have the actual ID. Added also function
4330 silc_hash_client_id_compare. The affected files are
4331 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4333 * When hashing the name associated with a ID it is always done
4334 in lowercase. This way we can access the cache without worrying
4335 about case-sensitivity, even though, for example nicknames are
4338 * Fixed a bug in server with channel message sending. It put
4339 wrong ID type as destination ID. The affected file
4340 silcd/packet_send.c.
4342 * silc_idcache_del_by_context now deletes from all hash tables
4343 by context. Affected file lib/silccore/idcache.c.
4345 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Changed the client library to use the new ID Cache interface.
4348 Changes around the source tree.
4350 * Added silc_hash_table_rehash_ext to rehash with specific
4351 hash function. Affected file lib/silcutil/silchashtable.[ch].
4353 * Added silc_hash_string_compare to compare two strings in the
4354 hash table. Affected file lib/silcutil/silcutil.[ch].
4356 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Added new function silc_idcache_del_by_context into the
4359 lib/silccore/idcache.[ch].
4361 * Changed the server's ID list routines to use the new ID Cache
4362 interface. Changes around the source tree.
4364 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Added silc_hash_table_del[_by_context]_ext functions in to the
4367 lib/silcutil/silchashtable.[ch].
4369 Removed silc_hash_table_find_all* routines and added new
4370 silc_hash_table_find_foreach to replace them.
4372 Added silc_hash_table_replace_ext function as extended
4373 replacing function. Separated the simple hash table interface
4374 from the extended hash table interface in the file
4375 lib/silcutil/silchashtable.h.
4377 * Fixed minor bugs and changed it to use some of the new
4378 hash table functions in lib/silccore/idcache.c
4380 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Added new function silc_hash_table_find_all to return all keys
4383 in the hash table by the specified key. As the hash table is
4384 collision resistant it also makes it possible to have several
4385 duplicate keys in the hash table. This function may be used to
4386 find all of the keys from the hash.
4388 Added user_context arguments to the SilcHashFunction,
4389 SilcHashCompare and SilcHashDestructor to deliver user specified
4392 Added new fuctions silc_hash_table_find[_all]_ext to do
4393 extended lookup with specified hash and compare functions and
4394 specified user contexts.
4396 Added new function silc_hash_table_add_ext to add the key
4397 with specified hash function and user context.
4399 Added new function silc_hash_table_foreach to traverse all
4400 entrys in the hash table. Added SilcHashForeach callback
4403 Added new function silc_hash_table_del_by_context to delete
4404 the entry only if the context associated with the key matches.
4406 Affected files are lib/silcutil/silchashtable.[ch].
4408 * Removed silc_hash_[server/client/channel]_id and added just
4409 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4410 silc_hash_id_compare to compare two ID's using as the hash table
4411 comparison function. Added also silc_hash_data to hash
4412 binary data and silc_hash_data_compare to compare it.
4414 * Removed silc_idlist_find_client_by_hash as it is not needed
4415 anymore. Affected file silcd/idlist.[ch].
4417 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4418 to use internally the SilcHashTable. The new ID Cache is a lot
4419 faster than the old one. Some of the ID Cache interface was also
4420 rewritten and obsolete and stupid functions were removed.
4422 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Added entry_count field to the SilcHashTable to keep the number
4425 of the entries in the table. Implemented the function
4426 silc_hash_table_rehash. Added new function
4427 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4429 Fixed a minor bug in silc_hash_table_free.
4431 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4432 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4433 into the lib/silcutil/silcutil.[ch].
4435 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Implemented a collision resistant hash table into the
4438 lib/silcutil/silchashtable[ch]. See the header and the source
4439 for the SilcHashTable API.
4441 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Merged dotconf version 1.0.2 into lib/dotconf.
4445 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Do not compile anything in lib/silcsim/* if the SIM support
4448 is not enabled. The tree should now compile without problems
4451 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Compiled the SILC under cygwin. Compiled and tested briefly
4454 without problems. More tests needed. The SIMs didn't compile
4457 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4459 * Fixed possible crash in silc_get_username in the
4460 lib/silcutil/silcutil.c.
4462 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Fixed a va_arg in silc/client_ops.c.
4466 * Oops, RC5 routines were named AES and caused some problems
4467 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4469 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Added new SilcIDIP structure into the lib/silccore/id.h and
4472 replaced the old `ip' fields from all SILC ID's to that type.
4473 This is a step towards IPv6 support.
4475 The silc_id_get_len takes now the ID as an extra argument.
4476 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4477 both IPv4 and IPv6 based ID's.
4479 The affected files are lib/silccore/id.[ch] and other files
4480 around the tree using these routines.
4482 * Removed the ID length arguments in server from various
4483 silc_server_send_notify_* routines -> they are not needed
4486 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4488 * Fixed memory leak in silc_encode_pem_file in the file
4489 lib/silcutil/silcutil.c.
4491 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Check minor version as well in the SKE. Affected files are
4494 silcd/protocol.c and lib/silcclient/protocol.c.
4496 * Added --identifier option to the server so that an identifier
4497 can be when creating the public key for the server. Affected
4498 file is silcd/silcd.c.
4500 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4501 lib/silccrypt/silcpkcs.c.
4503 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Register default ciphers and stuff when using -C option with
4506 the server. Affected file sildc/silcd.c.
4508 * Put back the servers public key filename format, it is better
4509 than the new one. For now, the client keys are saved with the
4510 new filename format. The affected file silc/client_ops.c.
4512 * Implemented the Cipher API for the rest of the ciphers that
4513 did not implement it or implemented it the wrong way.
4515 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Register default ciphers and stuff when using the -S option
4518 in the client. Affected file silc/silc.c. Same also when
4519 creating new key pair with -C option.
4521 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Fixed the silc_verify_public_key client operation function to
4524 save the public keys differently. The fingerprint is now
4525 used as filename and not the hostname. This way also the
4526 client keys are saved uniquely and not with hostnames. The
4527 affected file is silc/client_ops.c.
4529 * Trimmed the silc_hash_fingerprint function to remove extra
4530 whitespaces from the end of the fingerprint. The affected
4531 file is lib/silccrypt/silchash.c.
4535 * Added silc_cipher_register_default function to register all
4536 default ciphers. It can be used when configuration files
4537 does not exist and the application does not want any specific
4538 ciphers in any specific order.
4540 The SilcDList is now used as silc_cipher_list dynamically
4541 allocated cipher list. Removed the static list all together
4542 and now all ciphers must be allocated to the dynamic list.
4543 The silc_cipher_alloc routine was changed to check only the
4546 All silc_cipher_* routines that used to return int returns
4549 The affected files lib/silccrypt/silccrypt.[ch].
4551 * The same thing was done to silc_hash_* as for silc_cipher_*
4552 routines. Affected files lib/silccrypt/silchash.[ch].
4554 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4555 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4556 Added also silc_pkcs_[un]register[_default] functions.
4557 Removed the data_context from the PKCS API.
4559 * Added silc_hmac_register_default function to register default
4560 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4561 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4562 to unregister all hmacs at once.
4564 * Register the default ciphers, hash functions, PKCSs and HMACs
4565 if client's configuration file does not exist. The affected
4568 * The client did not load the hash functions from the SIM
4569 modules at all. Added support for this. Affected file is
4570 silc/clientconfig.c.
4572 * When decoding public key with silc_pkcs_public_key_decode, check
4573 the supported algorithm only if PKCS are registered. Affected
4574 file lib/silccrypt/silcpkcs.c. The same was done with the
4575 silc_pkcs_private_key_decode.
4577 * Fixed the SILC List routines to keep the list always in order.
4578 It used to change the list's order when traversing the list but
4579 not it preserves the order. Affected file lib/trq/silclist.h.
4581 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Added the client library to use the SilcSocketConnection's
4584 reference counter (by silc_socket_dup) to prevent the bug that
4585 the socket object may be freed underneath async operation.
4587 * The name resolv library checking fixes in the configure.in.pre.
4590 * Created new version of the protocol drafts for future
4591 development. The -03 drafts are the ones that will be changed
4592 in the trunk now and the -02 will remain as they are.
4594 * Send list of CUMODE notifys to the router when announcing
4595 the channel users to the router. Affected file silcd/server.c.
4596 If the router receiving channel founder CUMODE for a channel
4597 that already has channel founder it will send CUMODE notify
4598 to the sender to remove the channel founder rights from the
4599 announced client. Affected file silcd/packet_receive.c.
4601 * The CUMODE notify may now use Server ID as well as the entity
4602 who changes the mode. Updated protocool specs.
4604 * Updated INSTALL and README files.
4606 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * New web pages in the http://silc.pspt.fi. The pages was
4613 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Implemented the [DenyConnectin] config section in the server.
4616 Added silc_server_config_denied_conn to check whether incoming
4617 connection is denied. Affected file silcd/serverconfig.[ch].
4619 * Do not check the ports when checking the incoming configuration
4620 data if the port is 0, meaning any. Affected file is
4621 silcd/serverconfig.c.
4623 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Fixed buffer overflow in silc_string_compare in the file
4626 lib/silcutil/silcutil.c.
4628 * Fixed double free in silc_server_command_leave in the file
4631 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Fixed the version checking in the server. Affected file is
4636 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Fixed the configuration data fetching when accepting new
4639 connections in the server. Affected file silcd/server.c.
4641 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added `sender_entry' argument to the function
4644 silc_server_packet_relay_to_channel so that we can check
4645 whether some destination actually belongs to the same route
4646 the sender belongs (ie, we must not resend the packet to the
4647 sender). Affected file silcd/packet_send.[ch].
4649 * Added `servername' field to the SilcClientEntry in the server
4650 to hold the name of the server where client is from. Affected
4651 file is silcd/idlist.h.
4653 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Moved the channel message encrypting in the router betwen
4656 router connections from silc_server_channel_message to the
4657 silc_server_packet_relay_to_channel since we want to check
4658 whether we have anybody channel before encrypting anything.
4659 Affected files silcd/packet_[receive/send].c.
4661 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Fixed the [AdminConnection] server config section to support
4664 multiple entries. Affected file silcd/serverconfig.c.
4666 * Added support into the server to check the validity of the
4667 incoming connection before executing any KE or authentication
4670 * The connection configuration is now saved to the KE and
4671 connection auth protocol contexts and not fetched anymore in
4672 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4674 * The local hosts listenning address and port is also resolved
4675 now when starting the server. We want to have the socket object
4676 to include the real address and port for the listener. Added
4677 new function silc_net_check_local_by_sock into the files
4678 lib/silcutil/silcnet.[ch].
4680 * Fixed a broadcast bug in server -> do not broadcast if we
4683 * Fixed a routing bug. Do not route broadcast packets ever.
4684 Broadcast packets must be processed always and not routed since
4685 they may be destined to some other host than yourself and thus
4686 would get routed without no good reason. Affected file is
4689 * Added function silc_server_config_is_primary_route to check
4690 whether primary router connection has been configured (a router
4691 configuration that we are initiating). If there is not, we
4692 will assume that there is only two routers in the SILC network
4693 and we will use the incoming router connection as our primary
4694 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4696 * Changed the order of the broadcasting. Broadcast _after_ the
4697 packet has been processed not before. Affected file is
4700 * Fixed a [ClientConnection] parsing bug. The port was never
4701 parsed correctly thus resulting to port 0. Affected file
4702 silcd/serverconfig.c.
4704 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4705 argument and did not set the broadcast packet flag. Affected
4706 file silcd/packet_send.c. Fixed same bug in the function
4707 silc_server_send_notify as well.
4709 * If we receive NEW_ID packet for our own ID in the server, ignore
4712 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Removed the nickname from the Private Message Payload.
4717 Updated the code and the protocol specs.
4719 * Updated protocol specs for submitting to the IETF.
4721 * Tweaked the Random Number Generator a bit. Affected file
4722 lib/silccrypt/silcrng.c. Exported a new function
4723 silc_rng_[global]_add_noise which can be used to add more
4726 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Do not parse packets with different timeout when protocol
4729 is active -> may cause problem with rekey. Affected file
4732 * When server receives signoff notify it must not create
4733 new channel key if the client is on any channels since the
4734 sender of the signoff notify will create it.
4736 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added printing of error messages during SKE protocol from the
4739 failure packet sent by server during SKE. Affected file
4742 * Removed the client's failure_callback handling with timeout
4743 and handle it immediately when received.
4745 * The SKE library returned wrong type in SUCCESS and FAILURE
4746 packets. They must be 32 bit MSB not 16 bit MSB.
4748 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Ok, rewrote the logic of the re-key and now it seems to work.
4751 I tested it on high traffic with frequent re-keys without
4752 problems. Added hmac_receive (and renamed hmac to hmac_send)
4753 in SilcClientConnection in lib/silcclient/client.h and
4754 in SilcIDListData in silcd/idlist.h. Also, removed the
4755 SilcPacketParserContext's cipher and hmac fields as they are
4756 not needed anymore and actually caused some problems when
4757 the ciphers and hmac's changed underneath the packet parser.
4759 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * If re-key protocol is active then process the incoming packets
4762 synchronously since we must assure that icoming packets encrypted
4763 with the old key is processed before the new keys is set to
4764 use. This is true other packets than for REKEY packets.
4765 Affected file silcd/server.c. The same was done to client library
4766 as well, affected file lib/silcclient/client.c.
4768 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Fixed bug in client and server to accept the force send if
4771 the packet is send from silc_[server/client]_packet_process
4772 function. Otherwise the packets are never delivered, oops.
4774 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Disable force sending of packets when REKEY protocol is active.
4777 We must assure that no packet is sent directly when rekey is
4778 performed. All packets must be sent through packet queue.
4779 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4780 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4781 function is silc_[server/client]_packet_send_real to check
4784 * Replaced the SIM paths from example config files to
4785 /usr/local/modules. Also, make install creates now
4786 /usr/local/silc/logs directory to hold all the SILC server
4789 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Made the configure.in.pre work on Solaris. Patch by salo.
4793 * Made all ciphers compatible with non-x86 machines. Defined
4794 CBC mode macros into lib/silccrypt/ciphers_def.h.
4796 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Fixed the make install.
4800 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * When MAC computation fails the silc_packet_decrypt returned 0
4803 even though it was supposed to return -1. Fixed this. The
4804 affected file is lib/silccore/silcpacket.c.
4806 * Do not replace the config files in /etc/silc (in make install)
4807 if they already exist. Affected file ./Makefile.am.
4809 * Do not send re-key packets immediately but through packet queue.
4810 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4812 * Changed silc_net_check_host_by_sock to return FALSE if the
4813 IP/DNS could not be resolved. Though, it returns the IP address
4814 now even if it could not resolve it (but returns also FALSE).
4815 Affected file lib/silcutil/silcnet.[ch].
4817 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Added silc_pkcs_decode_identifier to decode the public key's
4820 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4821 Added also silc_pkcs_free_identifier. Added also new context
4822 SilcPublicKeyIdentifier.
4824 * Added -S option to the silc client. It is used to dump the
4825 contents of the specified public key file.
4827 * Changed the PKCS api to return the public key length when
4828 setting the public key.
4830 * Fixed a fatal bug in the public and private key file loading.
4831 Affected file lib/silccrypt/silcpkcs.c.
4833 * Execute the packet parsing for client with zero (0) timeout
4834 if the protocol is active. Affected file silcd/server.c.
4836 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Made the key generation options to the silcd program. Added
4839 -C option, equivalent to client's option.
4841 * Added new [ServerKeys] config section to the server. It
4842 configures the server's public and private key.
4844 * Defined generic Public Key Payload into the protocol
4845 specification to send specific type of public keys and
4848 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4849 public key or certificate.
4851 * Implemented the GETKEY command to the server and to the
4852 client library and on user interface.
4854 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Made preliminary `make install' work.
4858 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Added SilcServerRekey context into silcd/idlist.h.
4862 * Added the PFS support as defined in the specification to the
4863 SKE protocol. Affected files lib/silcske/*.c.
4865 * Added `ske_group' field to the SilcServerRekey context to hold
4866 the number of the SKE group that is used with PFS in re-key.
4867 Affected file silcd/idlist.h.
4869 * Added PFS re-key support to the server. Affected file is
4872 * Added silc_protocol_cancel to cancel execution of the next
4873 state of the protocol. Affected file is
4874 lib/silccore/silcprotocol.[ch].
4876 * Added the re-key support with and without PFS to the client
4877 library. Re-key is performed once in an hour, by default.
4879 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4880 Added silc_client_rekey_callback and silc_client_rekey_final.
4881 Affected files are lib/silcclient/protocol.[ch] and
4882 lib/silcclient/client.[ch].
4884 * Removed the `hmac_key' and `hmac_key_len' fields from the
4885 SilcClientConnection structure; not needed. Affected file is
4886 lib/silcclient/client.h.
4890 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Do not ask whether user wants to use the negotiated private key
4893 for private messages, just use it. Affected file is
4894 silc/local_command.c.
4896 * Added `send_enc_key' and `enc_key_len' fields to the
4897 SilcIDListData structure since they are needed in the re-key
4898 phase. Affected file is silcd/idlist.[ch].
4900 * Implemented the simple re-key protocol into the server.
4901 Affected files silcd/server.c and silcd/protocol.[ch]. The
4902 re-key will be performed once in an hour, by default.
4904 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4905 Added silc_server_rekey, silc_server_rekey_callback and
4906 silc_server_rekey_final.
4908 * Removed Tunneled flag from the protocol. Updated the code
4909 and the specifications.
4911 * Adde `pfs' field to the SilcIDListData to indicate whether
4912 the PFS is to be performed in the re-key. Affected file is
4915 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4918 int64 of at least the xintXX size. If void * is less that 4
4919 bytes uint32 * will be used. Defined bool as boolean.
4921 * Changed _ALL_ unsigned long and unsigned int to uint32,
4922 unsgined short to uint16 in the source tree.
4924 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4925 not handle clients that has entry->data.registered == FALSE.
4926 They are not in the network anymore. Affected file is
4929 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Implemented the sending of the SERVER_SIGNOFF notify in the
4932 server. Affected file is silcd/server.c.
4934 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4935 Added also silc_notify_payload_encode_args into the
4936 lib/silccore/silcnotify.[ch].
4938 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4939 Affected file silcd/packet_receive.c.
4941 * Implemented the SERVER_SIGNOFF notify handling in the client
4942 library. Affected file lib/silcclient/client_notify.c. Also,
4943 implemnted the printing of the SERVER_SIGNOFF info to the
4944 application. Affected file silc/client_ops.c.
4946 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4947 if the deleting was successful. Affected file silcd/idlist.[ch].
4949 * Added support for public key authentication in the connection
4950 authentication protocol in the client library. Affected file
4951 lib/silcclient/protocol.c.
4953 * Changed the server's silc_idlist_get_clients_by_* interface
4954 to support already allocated array so that new entries may be
4955 added to pre-allocated array. Affected file silcd/idlist.[ch].
4956 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4957 and command replies.
4959 * All command reply functions in the server now calls the
4960 pending command callback even if error occured. This way the
4961 error will be delivered to the client as well. Affected files
4962 silcd/command.c and silcd/command_reply.c.
4964 * Fixed INFO command to return local server's info if no server
4965 was provided. Affected file lib/silcclient/command.c.
4967 * Removed RESTART command for good. Updated the code and the
4970 * Rewrote parts of the task system. It is a bit simpler now.
4971 Removed unsued task priorities. The affected files are
4972 lib/silcutil/silctask.[ch].
4974 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Moved the USERS printing from the library to the application.
4977 Affected files lib/silcclient/command.c and silc/client_ops.c.
4979 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Added channel key re-key support. The re-key is perfomed
4984 only by the router and is done once in an hour. Added `rekey'
4985 field to the SilcChannelEntry in the server. Affected files
4986 silcd/server.c and silcd/idlist.h.
4988 * Added silc_task_unregister_by_context into the file
4989 lib/silcutil/silctask.[ch].
4991 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Added SILC_UMODE_GONE mode to indicate when the client is not
4994 present in the SILC network. Added also support to the local
4995 command AWAY that will set this mode. Added support of showing
4996 "xxx is gone" in WHOIS command. The USERS command shows the
4997 gone status as well.
4999 * Fixed setting server and router operator privileges in the
5000 server's UMODE command. Affected file silcd/command.c.
5002 * Merged the SKE KE1 and KE2 payloads into one payload. The
5003 new KE payload is equivalent to the old KE2 payload.
5005 Cleaned up the SKE Start Payload parsing. It now uses the
5006 simple buffer unformatting to do the parsing. A lot faster
5009 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5010 to the SKE that is used to indicate whether both of the SKE
5011 parties should perform authentication. By default only the
5012 responder performs authentication. By setting this flag also
5013 the initiator must do authentication. By default it is unset
5014 since in normal SKE case, client to server connection, only
5015 the responder should do authentication. When doing SKE between
5016 two clients both should perform authentication. Updated the
5017 code and the protocol specs.
5019 * A little fix to IDENTIFY command in the server. Search the
5020 client first by hash not nickname. Affected file is
5023 * Fixed the silc_client_close_connection to support closing
5024 the client to client connections wihtout deleting too much
5025 data. Affected file lib/silcclient/client.c.
5027 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5028 are received if protocol used to be active but is not anymore
5029 the application would crash due to NULL pointer dereference.
5030 Affected files silcd/server.c and lib/silcclient/client.c.
5032 * Added `hash' field to the SilcClientConnection to include
5033 the hash function negotiated in the SKE protocol.
5035 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5036 to set the channel founder authentication data. A client can
5037 claim the founder rights later by providing the authentication
5038 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5039 This way the channel founder can regain the channel founder
5040 privileges even it is left the channel. This works only on
5041 local server and the client must be connected to the same
5042 server to be able to regain the founder rights. Updated the
5043 protocol specs accordingly.
5045 Added support to the CMODE command in the client to set the
5046 founder auth data. Read the README to see how to set it.
5048 Added support to the CUMODE command to claim the founder
5049 rights. Read the README to see how to do it.
5051 Added support for the founder authentication to the Channel
5052 Entry in the server. Affected file silcd/idlist.h.
5054 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5055 server's CMODE command. Affected file silcd/command.c.
5057 * Added the following new functions into lib/silccore/silcauth.[ch]:
5058 silc_auth_get_method and silc_auth_get_data.
5060 * The server now saves the remote hosts public key to the
5061 SilcIDListData pointer. Affected file silcd/protocol.c.
5063 * The normal server now does not remove the channel entry from
5064 the cache if the founder authentication data is set. It used
5065 to remove it if the founder was the last one on the channel on
5066 the server and left the channel. The auth data is saved and
5067 if the channel is re-joined later the old entry is used with
5068 the old auth data. Affected files silcd/command_reply.c and
5071 * Removed the `pkcs' field from the SilcIDListData structure
5072 in the server; it is not used. Affected file silcd/idlist.h.
5074 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Fixed packet processing on slow links. Partial packets were
5077 never re-processed because the incoming data buffer was cleared
5078 by the application. Application must not directly clear the
5079 sock->inbuf, the packet processing routines handle it. Fixed
5080 this in client library and in server.
5082 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Fixed the WHOIS and IDENTIFY send reply function to really
5085 check whether to send list or just one entry. Affected file
5088 * Cleaned up the LEAVE command's channel key distribution. The
5089 affected file silcd/command.c.
5091 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5092 can enforce the channel mode as well. In that case the ID
5093 includes the ID of the server. The code now enforces the
5094 mode change if the router have different mode than the server.
5096 * The notify client operation with CMODE_CHANGE notify can now
5097 return NULL client_entry pointer if the CMODE was not changed
5098 by client. Application must check for this.
5100 * Added <Server ID> argument to INFO command to support server
5101 info fetching by Server ID.
5103 * Added silc_server_announce_get_channel_users to get assembled
5104 packets of channel users of the specified channel. Affected
5105 file silcd/server.[ch].
5107 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5108 was freed underneath the ID Cache.
5110 * Re-announce clients when the server received CHANNEL_CHANGE
5111 notify from the router. Affected file silcd/packet_send.c.
5113 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5116 crashed since it did not handle the fact that there is no cipher
5117 called "3" and didn't check the error condition. Now fixed.
5119 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5120 flag. It can be used to send message requests.
5122 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Implemented the RESTART command in the client.
5126 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5127 notice type messages. Added notice printing to the user
5130 * The channel keys are not re-generated if the channel's mode
5131 is PRIVKEY, ie private key on the channel exists. Affected
5132 files silcd/server.c and silcd/command.c.
5134 * Fixed a little bug in channel message delivery when channel
5135 private keys are set in the server. Affected file is
5136 silcd/packet_send.c.
5138 * Changed the setting on channel->on_channel = TRUE from the
5139 silc_client_save_channel_key to the JOIN command reply. The
5140 key payload is not received if the private channel key is set.
5141 Affected file lib/silcclient/command_reply.c and the
5142 lib/silcclient/client_channel.c.
5144 * When the CMODE_CHANGE notify is sent and the channel private
5145 key mode is removed the channel key must be re-generated in
5146 other cells as well. Added this support for the router in the
5147 silcd/packet_receive.c.
5149 * Added new local command NOTICE to send notice message on
5150 channel. Affected file silc/local_command.[ch].
5152 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Added new local command ME to the client. It is used to send
5155 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5156 some action. Affected file silc/local_command.[ch].
5158 * Changed channel_message and private_message client operations
5159 to deliver the message flags to the application. Added also
5160 the `flags' arguments to the silc_client_send_channel_message
5161 and silc_client_send_private_message functions. Affected file
5164 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Redefined the Private Message Payload to support private message
5167 keys and to support the new private message flags. Updated
5168 the protocol specs. Flags makes it possible to have for example
5169 CTCP style messages.
5171 * Added new type SilcPrivateMessagePayload and defined an API
5172 for it in the lib/silcclient/silcprivate.[ch].
5174 * Tested private message private keys successfully. Tested the
5175 private message key set, unset and list commands with the new
5178 * Redefined the Channel Message Payload to include the channel
5179 message flags (equal with private message flags) to support
5180 for example CTCP style messages.
5182 * Defined some of the message (for channel and private message)
5183 flags. Updated the protocol specs and added the flags to the
5184 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5186 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Added SilcKeyAgreementStatus type to the key agreement routines
5189 to indicate the current status and error if one occured.
5190 The status types are defined in the lib/silcclient/silcapi.h.
5192 * Added new local command KEY that is used to set and unset private
5193 keys for channels, set and unset private keys for private messages
5194 with remote clients and to send key agreement requests and
5195 negotiate the key agreement protocol with remote client. The
5196 key agreement is supported only to negotiate private message keys,
5197 it currently cannot be used to negotiate private keys for channels,
5198 as it is not convenient for that purpose.
5200 * Fixed a minor pending callback setting bug in the function
5201 silc_client_get_client_by_id_resolve, now the function works.
5202 Affected file lib/silcclient/idlist.c.
5204 * Added function silc_net_get_local_port to get local bound
5205 port by socket. Added to lib/silcutil/silcnet.[ch].
5207 * Added `sockets' and `sockets_count' fields to the SilcClient
5208 object. They hold the sockets of the listenning sockets in
5209 the client. Listenning sockets may be for example the key
5210 agreement server. Affected file lib/silcclient/client.[ch].
5211 Added functions the silc_client_add_socket and the
5212 silc_client_del_socket. They are exported to the application
5215 * Added ~./silc/clientkeys to support other client's public keys.
5217 * Renamed verify_server_key client operation to verify_public_key
5218 and added one argument to indicate the type of the connection
5219 (server, client etc.).
5221 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Added silc_server_connection_auth_request to handle the
5224 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5225 silcd/packet_receive.[ch].
5227 * Added silc_server_send_connection_auth_request into the
5228 silcd/packet_send.c to send the connection auth request packet.
5230 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5233 * Fixed the public key authentication in responder side in the
5234 server. The `auth_data' pointer includes the SilcPublicKey
5235 not the path to the public key. Affected file silcd/protocol.c.
5237 * Implemented the public key authentication in the initiator side
5238 in the server. Affected file silcd/protocol.c.
5240 * Removed the [RedirectClient] config section from the server
5241 configuration. Is not needed and I don't want to implement it.
5243 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Cleaned up the CMODE command in the server. It now works
5246 correctly and supports all the modes defined in the protocol.
5247 Affected file is silcd/command.c.
5249 * Added `hmac_name' field to the SilcChannelEntry in the server
5250 to hold the default HMAC of the channel. It can be set when
5251 creating the channel (with JOIN command). Affected files
5254 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5255 type to indicate the change of the current cipher and hmac
5256 on the channel. Client can safely ignore the <cipher> argument
5257 (if it chooses to do so) since the CHANNEL_KEY packet will
5258 force the channel key change anyway. The <hmac> argument is
5259 important since the client is responsible of setting the new
5260 HMAC and the hmac key into use.
5262 * Fixed the CMODE command in the client library as well.
5264 * Tested CMODE command in router environment successfully.
5266 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Show the version of the remote client (or server) when connecting
5269 to the server. It is logged to the log file. Affected file
5270 is silcd/protocol.c.
5272 * Fixed the KILLED notify handling in the client library. The
5273 client must be removed from all channels when receiving the
5276 Also, do not remove the client entry when giving the KILL
5277 command but when the KILLED notify is received.
5279 * Removed silc_idlist_find_client_by_nickname from the server.
5280 Not needed anymore. Affected files silcd/idlist.[ch].
5282 * Implemented the CHANNEL_CHANGE notify type handling to the
5283 server. Affected file silcd/server.c.
5287 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5290 notify between routers.
5292 * Implemented the INVITE command correctly to the server.
5294 * Implemented the INVITE notify type handling in the server.
5296 * Implemented the INVITE command to the client library and on the
5299 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * Added function silc_server_get_client_resolve to find the
5302 client entry by ID from all ID lists and then resolve it
5303 (using WHOIS) if it cannot be found. Affected file is
5306 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Implemented the BAN command to the client library.
5310 * The JOIN command in the server now checks the invite list
5313 * Changed the silc_command_reply_payload_encode_va and the
5314 silc_command_payload_encode_va to support that if argument is
5315 NULL it ignores and checks the next argument. Affected file
5316 lib/silccore/silccommand.c.
5318 * Added silc_server_send_notify_ban to send the BAN notify
5319 type between routers.
5321 * Chaned the silc_notify_payload_encode to support that if
5322 argument is NULL it ignores and checks the next argument.
5323 Affected file lib/silccore/silcnotify.c.
5325 * Tested ban lists in router environment successfully.
5327 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Implemented BAN command to the server, in silcd/command.[ch].
5331 * Removed the BAN and INVITE_LIST modes from the CMODE command
5334 * Added function silc_string_match to regex match two strings.
5335 Affected files lib/silcutil/silcutil.[ch].
5337 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Redefined parts of the SilcChannelEntry in the server to support
5340 the new ban and invite lists.
5342 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Redefined the INVITE command. The same command can be used to
5345 invite individuals to the channel but also to manage the invite
5346 list of the channel (to add to and remove from the invite list).
5347 Updated the protocol specs.
5349 * Added new command SILC_COMMAND_BAN that can be used to manage
5350 the ban list of the channel. Updated the protocol specs.
5352 * Removed the channel modes: the SILC_CMODE_BAN and the
5353 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5354 in the CMODE command. The equivalent features are now available
5355 using INVITE and BAN commands. Updated the protocol specs.
5357 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5358 in the network about change in the current ban list. The notify
5359 type is not used by the client.
5361 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5362 support the invite lists.
5364 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Added new function silc_string_regexify that converts string
5367 including wildcard characters into regex string that can
5368 be used by the GNU regex library. Added into the file
5369 lib/silcutil/silcutil.[ch].
5371 Added silc_string_regex_combine to combine to regex strings
5372 into one so that they can be used as one regex string by
5373 the GNU regex library. Added into the file
5374 lib/silcutil/silcutil.[ch].
5376 Added silc_string_regex_match to match two strings. It returns
5377 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5379 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Imported GNU regex to the soruce tree into lib/contrib.
5382 Fixed some compiler warning from the regex.c.
5384 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Fixed MOTD command in the server to work in router environment.
5388 * Fixed the MOTD command in the client library to support
5389 the server argument in the command.
5391 * Added `nickname_len' argument to the silc_idlist_add_client
5392 in the server, as the `nickname' argument may be binary data
5395 * Added silc_idlist_get_channels to return all channels from
5398 * Implemented LIST command to the server. Affected file is
5401 * Implemented the LIST command to the client library and on the
5404 * Added [<user count>] argument to the LIST command reply.
5405 With private channels the user count is not shown.
5407 * Updated TODO and README.
5409 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * The client entry's data.registered must be TRUE even with
5412 global client entry on global client list. The data.registered
5413 is used to check whether the client is anymore in the network,
5414 for example with WHOWAS command so it must be valid.
5416 * Fixed the WHOWAS command in the server. It now actually works
5417 in router environment. Added function into silcd/command_reply.c
5418 silc_server_command_reply_whowas_save.
5420 * Added silc_idlist_purge function to the silcd/idlist.c
5421 to periodically purge the ID Cache.
5423 * Fixed INFO command in the server. It works now in router
5424 environment. Added <server name> argument to the INFO command
5425 reply. Updated the protocol specs.
5427 * Fixed minor bug in silc_idcache_purge to not purge if the
5428 expire value is zero.
5430 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5431 they were buggy because of the WHOWAS information.
5433 * Fixed local command MSG to handle the async resolving of
5434 the remote client properly. It used to fail the first MSG.
5435 Affected file silc/local_command.c.
5437 * Added `data_len' field to SilcIDCache context.
5439 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Update TODO. Todo in commands in the server.
5443 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5446 used by routers as broadcast packet to inform other routers
5447 about the changed user mode.
5449 Implemented the notify handling in the server. Affected file is
5450 silcd/packet_receive.c. Added the function
5451 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5453 * Added new generic Channel Payload and deprecated the New Channel
5454 Payload. The New Channel Payload is now the generic Channel
5457 * Added new argument `mode' to the silc_server_send_new_channel
5458 as it is required in the Channel Payload now.
5460 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5461 and created a new and real SilChannelPayload to represent the
5462 new generic Channel Payload. Implemented the encode/decode
5463 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5465 * Added silc_server_get_client_channel_list to return the list
5466 of channels the client has joined for WHOIS command reply.
5467 Affected file silcd/server.[ch].
5469 * Implemented the channel list sending in the WHOIS command reply
5470 in server and in the client.
5472 Implemented the channel list displaying on the user interface
5473 as well. Affected file silc/client_ops.c.
5475 * Added silc_channel_payload_parse_list to parse list of Channel
5476 Payloads. It returns SilcDList list of SilcChannelPayloads.
5477 Client for example can use this function to parse the list of
5478 channels it receives in the WHOIS command reply. The caller
5479 must free the list by calling silc_channel_payload_list_free.
5480 Affected files lib/silccore/silcchannel.[ch].
5482 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Added one new argument <user mode> to the WHOIS command reply
5485 to return the mode of the user in SILC. Updated the protocol
5488 Implemented it to the server and client.
5490 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Fixed the mode printing on the user interface on joining.
5493 Affected file silc/client_ops.c.
5495 * Implemented the UMODE command and user modes in general to the
5496 client library and to the user interface.
5498 * Implemented the UMODE command to the server.
5500 * The server now sends UNKNOWN_COMMAND error status if client sends
5501 unknown command. Affected file silcd/command.c.
5503 * All server commands now handle the command identifier the right
5504 way when sending the command reply to the client. The client can
5505 use to identify the command replies with the identifier.
5507 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Added silc_server_get_client_route to resolve the route to
5510 the client indicated by the client ID. Affected file is
5513 * Added silc_server_relay_packet as general function to relay
5514 packet to arbitrary destination. This deprecates functions
5515 like _send_private_message_key, _relay_notify etc. Affected
5516 file is silcd/packet_send.[ch].
5518 Removed silc_server_send_key_agreement,
5519 silc_server_send_private_message_key and
5520 silc_server_packet_relay_notify functions from the file
5521 silcd/packet_send.[ch].
5525 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5526 server. Affected file silcd/packet_receive.[ch].
5528 * Implemented the KILL command to the client. Implemented the
5529 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5530 Affected files lib/silcclient/command[_reply].c and
5531 lib/silcclient/client_notify.c. Implemented the KILL notify
5532 printing in the user inteface.
5534 * Fixed a lot silc_parse_nick memory leaks from the client
5535 library in the file lib/silcclient/command.c.
5537 * Changed the silc_server_send_notify_on_channels's `sender'
5538 argument from SilcSocketConnection to SilcClientEntry to
5539 check the sender as entry and not as connection object and not
5540 to send to the client provided as argument. The affected file
5541 is silcd/packet_send.[ch].
5543 * The notify packets that are destined directly to the client used
5544 to not to be processed by the server. Now changed that and the
5545 server processes all notify packets. After relaying the packet
5546 to the client the notify packet is processed in the server.
5548 * The silc_server_free_client_data now checks whether there is
5549 pending outgoing traffic for the client and purges the data to
5550 the network before removing the client entry.
5552 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5555 an client is killed from the SILC Network. Updated the protocol
5558 Added new function silc_server_send_notify_killed to the
5559 silcd/packet_send.[ch].
5561 * Added function silc_server_packet_relay_notify to relay notify
5562 packets that are destined directly to a client. In this case
5563 the server does not process the notify packets but merely relays
5564 it to the client. Affected file silcd/packet_send.[ch].
5566 Added also silc_server_packet_process_relay_notify to check
5567 whereto relay the notify. Affected file is
5568 silcd/packet_receive.[ch].
5570 * Implemented the KILL command to the server.
5574 * Added the backup schema desgined last fall to the protocol
5575 specs for everyone to see. The specification is in the
5576 *-spec-xx.txt draft and the packet type definitions for the
5577 backup routers is in *-pp-xx.txt draft. Thusly, added also
5578 new packet type SILC_PACKET_CELL_ROUTERS.
5580 * A big security problem in the implementation discovered. The
5581 signoff of an client did not cause new channel key generation
5582 which it of course should've done. The channel keys must be
5583 always re-generated when client leaves (or signoffs) the channel.
5584 The silc_server_remove_from_channels funtion now handles
5585 the channel key re-generation.
5587 * Added `sender' argument to the silc_server_send_notify_on_channels
5588 to not to send the client provided as argument. Affected file
5589 silcd/packet_send.[ch].
5591 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Implemented OPER and SILCOPER commands into the server and
5596 * Added silc_auth_verify and silc_auth_verify_data to verify
5597 the authentication directly from the authentication payload.
5598 It supports verifying both passphrase and public key based
5599 authentication. Affected file lib/silccore/silcauth.[ch].
5601 * Added `hash' field to the SilcIDListData structure. It is the
5602 hash negotiated in the SKE protocol. Affected file is
5605 * Slight redesigning of the SilcAuthPayload handling routines.
5606 Do not send SilcPKCS but SilcPublicKey as argument.
5608 * Implemented the public key authentication support to the
5609 serverconfig. The public key is loaded from the provided path
5610 and saved as authentication data to void * pointer. Thus,
5611 changed the unsigned char *auth_data to void *auth_data;
5613 * Fixed SHUTDOWN command to send the reply before the server
5614 is shutdown. :) Affected file silcd/command.c.
5616 * Fixed fatal bug in CONNECT command. The hostname was invalid
5617 memory and server crashed. Affected file silcd/command.c.
5619 * Fixed fatal bug in CLOSE command. The server_entry became
5620 invalid but was referenced later in the command. Affected file
5623 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Fixed fatal bug in failure packet handling. Server ignored
5626 the failure and thus crashed when it came.
5630 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5633 that the command may be executed only once in (about) 2 seconds.
5634 The old SILC_CF_LAG flag is same but allows command bursts up
5635 to five before limiting.
5637 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5638 server code. Various commands now includes the CF_LAG_STRICT
5639 flag to disallow any kind of miss-use of the command.
5641 * Fixed the silc_buffer_unformat to not to allocate any data
5642 if the length of the data is zero. It used to allocate the
5643 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5645 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Changed the format of AdminConnection configuration section
5648 in the server. Added username of the admin to the format.
5649 Affected files silcd/serverconfig.[ch].
5651 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5652 to return admin configuration data by host, username and/or
5655 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Implemented WHOWAS command to the server. Added the functions:
5659 silc_server_command_whowas_parse,
5660 silc_server_command_whowas_send_reply,
5661 silc_server_command_whowas_from_client and
5662 silc_server_command_whowas_from_server
5664 * Added <Client ID> argument to the WHOWAS command reply. Updated
5665 the protocol specs accordingly.
5667 * Implemented WHOWAS command and command_reply to the client
5670 Implemented the WHOWAS printing on the user interface.
5672 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Added new argument to the WHOWAS command reply, the real name.
5675 It is an optional argument. Updated the protocol specs.
5677 * Added SilcIDCacheDestructor callback that is registered when
5678 the SilcIDCache is allocated. The callback is called when
5679 an cache entry in the ID Cache expires, or is purged from the
5680 cache. Added into lib/silccore/idcache.[ch].
5682 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5683 to destruct the client entries when the cache entry expires.
5684 Other ID Cache's in server and in the client library ignores
5687 * If the ID Cache entry's `expire' field is zero then the entry
5688 never expires. Added boolean `expire' argument to the
5689 silc_idcache_add function in the lib/silccore/idcache.[ch].
5690 If it is TRUE the default expiry value is used.
5692 * Added silc_server_free_client_data_timeout that is registered
5693 when client disconnects. By default for 5 minutes we preserve
5694 the client entry for history - for WHOWAS command.
5696 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Added support to the server to enforce that commands are not
5699 executed more than once in 2 seconds. If server receives
5700 commands from client more frequently, timeout is registered
5701 to process the commands. Affected file silcd/command.c.
5702 Added new function silc_server_command_process_timeout.
5704 * Changed NICK_NOTIFY handling in client library to check that
5705 if the client's nickname was changed, so there is no need to
5706 resolve anything from the server.
5708 * Removed error printing from the WHOIS and IDENTIFY commands.
5709 If error occurs then it is ignored silently in the client library.
5710 The application, however, may map the received error to
5711 human readable error string. The application currently maps
5712 the NO_SUCH_NICKNAME error to string.
5714 * Made the command status message public to the application. Moved
5715 them from lib/silcclient/command_reply.c to
5716 lib/silcclient/command_reply.h. The application can map the
5717 received command status to the string with the
5718 silc_client_command_status_message function.
5720 * Added check to the server to check that client's ID is same
5721 as the Source ID in the packet the client sent. They must
5724 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Added dist-bzip hook to the Makefile.am to make bzip2
5727 compressed distributions.
5729 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Server now enforces the maximum length for the nickname and
5732 the channel as protocol specification dictates. 128 bytes for
5733 nickname and 256 bytes for channel name.
5735 * Moved the WHOIS printing to the application. The client libary
5736 does not print out the WHOIS information anymore, the application
5737 must do it. Renamed silc_client_command_reply_whois_print to
5738 the silc_client_command_reply_whois_save.
5740 The client's idle time is also sent to the application now, and
5741 the idle is shown on screen.
5743 * Added silc_client_command_reply_identify_save to save the
5744 received IDENTIFY entries.
5746 * Do not check for channel private keys in message sending and
5747 reception if the channel does not have the PRIVKEY mode set.
5748 Affected file lib/silclient/client_channel.c.
5750 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5753 just surfaced after chaning the JOIN procedure.
5755 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Added silc_client_get_clients_by_list to get client entries
5758 from Client ID list, that is returned for example by JOIN
5759 and USERS command replies. The application should use this
5760 function for example when JOIN command reply is received to
5761 resolve the clients already on the channel (library does not
5762 do that anymore as USERS command reply is not used in the JOIN
5763 procedure anymore). Affected files lib/silcclient/silcapi.h and
5764 lib/silcclient/idlist.c.
5766 * JOIN command reply and USERS command reply returns now SilcBuffer
5767 pointers instead of unsigned char pointers when returning
5768 the client list and mode list.
5770 * Added <Client ID> argument to the JOIN command reply, mainly
5771 for the server to identify for which client the command was
5772 originally sent. Updated protocol specs accordingly.
5774 * Added SilcDlist private_key pointer to the SilcChannelEntry
5775 in the client to support the channel private keys. Affected
5776 file is lib/silcclient/idlist.h.
5778 * Added SilcChannelPrivateKey argument to the function
5779 silc_client_send_channel_message so that application can choose
5780 to use specific private ke if it wants to. If it is not provided,
5781 the normal channel key is used, unless private keys are set.
5782 In this case the first (key that was added first) is used
5783 as the encryption key.
5785 * Implemented the support for channel private key handling.
5786 Implemented the following functions:
5788 silc_client_add_channel_private_key,
5789 silc_client_del_channel_private_keys,
5790 silc_client_del_channel_private_key,
5791 silc_client_list_channel_private_keys and
5792 silc_client_free_channel_private_keys
5794 Affected file lib/silcclient/client_channel.c.
5796 * Added the support for the private keys in the channel message
5797 sending and encryption and in the message reception and
5798 decryption. Affected funtions are
5799 silc_client_send_channel_message and silc_client_channel_message.
5801 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Added SKE's key verify callback to the client library's
5804 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5806 * Removed the statement that server (or router) must send USERS
5807 command reply when joining to the channel so that the client
5808 knows who are on the channel. Instead, the client list and
5809 client's mode list is now sent in the JOIN command reply to the
5810 client who joined channel. This is better solution.
5812 * Added function silc_server_get_users_on_channel and function
5813 silc_server_save_users_on_channel to the silcd/server.[ch].
5815 * Removed function silc_server_command_send_users from the
5818 * Do not show topic on the client library anymore. The topic is
5819 sent in the command reply notify to the application and the
5820 application must show the topic now.
5822 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Added client searching by nickname hash into the IDENTIFY and
5825 WHOIS commands in the server as they were clearly missing from
5826 them. Affected file is silcd/command.c.
5828 * Fixed a bug in private message receiving in the client library.
5829 The remote ID was freed and it wasn't supposed, now it is
5832 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Minor fix to the channel payload; allocate the data area, as it
5835 needs to be of specific length.
5837 * If the key agreement port is zero then the operating
5838 system will define the bound port. Affected files are
5839 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5841 * Added new function silc_channel_payload_decrypt into the file
5842 lib/silccore/silcchannel.[ch].
5844 * Moved the channel message etc, check from silc_packet_decrypt
5845 to applications. The library calls now a generic
5846 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5847 when the packet is either normal or special. This was done to
5848 allow more wide range of checking that was not allowed when
5849 the code was in library. Now applications can do virtually any
5850 checks to the packet and return to the library the decision how
5851 the packet should be processed. Affected files are
5852 lib/silccore/silcpacket.[ch].
5854 Added silc_server_packet_decrypt_check to the server and
5855 silc_client_packet_decrypt_check to the client library.
5857 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5858 to send with specified source and destination information.
5860 * Channel message delivery between routers was broken after the
5861 channel key distribution was fixed earlier. The channel key
5862 was used be to distributed to other routers as well which is not
5863 allowed by the protocol. Now this is fixed and channel keys
5864 really are cell specific and the channel message delivery between
5865 routers comply with the protocol specification.
5867 * Fixed various commands in server to check also the global list
5868 for the channel entry and not just the local list. The affected
5869 file silcd/command.c.
5871 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Added assert()s to buffer formatting and unformatting routines
5874 to assert (if --enable-debug) when error occurs. Affected
5875 file: lib/silcutil/silcbuffmt.c.
5877 * Changed to auto-reconnect to check whether the remote host is
5878 router and register the re-connect timeout if it is. It used
5879 to check that whether we are normal server, but router must do
5880 auto-reconnect with another router as well. Affected file
5883 * Removed the [<key len>] option from CMODE command as the cipher
5884 name decides the key length, nowadays. See the defined ciphers
5885 from the protocol specification.
5887 * Added [<hmac>] option to the CMODE command to define the HMAC
5888 for the channel. Added SILC_CMODE_HMAC channel mode.
5890 * Added [<hmac>] option for the JOIN command so that user can
5891 select which HMAC is used to compute the MACs of the channel
5894 * Added Hmac field to the Channel Message Payload. The integrity
5895 of plaintext channel messages are now protected by computing
5896 MAC of the message and attaching the MAC to the payload. The
5897 MAC is encrypted. Now, it is clear that this causes some
5898 overhead to the size of the packet but rationale for this is that
5899 now the receiver can verify whether the channel message decrypted
5900 correctly and also when private keys are set for the channel the
5901 receiver can decrypt the packet with several keys and check from
5902 the MAC which key decrypted the message correctly.
5904 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5905 lib/silccrypt/silccipher.[ch].
5907 * Added silc_hash_len to return the digest length into the
5908 lib/silcrypt/silchash.[ch].
5910 * Rewrote parts of Silc Channel Payload interface in the
5911 lib/silccore/silcchannel.[ch]. The encode function now also
5912 encrypts the packet and parse function decrypts it.
5914 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Fixed a minor formatting bug in the SKE's key material processing.
5917 It actually might have processed the keys wrong way resulting
5920 * Redefined the mandatory HMAC algorithms and added new algorithms.
5921 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5922 and hmac-md5 truncated to 96 bits. The mandatory is now
5923 hmac-sha1-96. Rest are optional (including the one that used
5924 to be mandatory). Rationale for this is that the truncated HMAC
5925 length is sufficient from security point of view and can actually
5926 make the attack against the HMAC harder. Also, the truncated
5927 HMAC causes less overhead to the packets. See the RFC2104 for
5930 * Added new [hmac] configuration section. The SKE used to use
5931 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5932 is of course wrong. The official names that must be proposed in
5933 the SKE are the ones defined in the protocol specification
5934 (hmac-sha1-96 for example). The user can configure any hmac
5935 using any hash function configured in the [hash] section. At
5936 least, the mandatory must be configured.
5938 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5940 * Added HMAC list to the SKE proposal list. It has now both
5941 hash algorithm list and HMAC list. This makes the protocol
5942 incompatible with previous versions. The SKE now seems to work
5943 the way it is supposed to work, for the first time actually.
5945 * Defined plain Hash algorithms to the protocol specification.
5948 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Implemented support for key agreement packets into the server.
5951 Added functions silc_server_key_agreement and
5952 silc_server_send_key_agreement. Other than these functions,
5953 server has nothing to do with this packet.
5955 * Added support for private message key packets into the server.
5956 Added functions silc_server_private_message_key and
5957 silc_server_send_private_message_key.
5961 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5962 called in the protocol's final callback instead in the END
5963 protocol state. This makes a little more sense and in the same
5964 time in client we can use the same protocol routines for normal
5965 key exchange and to key agreement packet handling as well.
5967 * Added to both client's and server's KE protocol context the
5968 SilcSKEKeyMaterial pointer to save the key material. We will
5969 bring the key material to the protocol's final callback by doing
5970 this. The final callback must free the key material.
5972 * Added SKE's packet_send callback into client's KE protocol
5973 context so that the caller can choose what packet sending function
5974 is used. This way we can use different packet sending when
5975 doing normal SKE when doing key agreement packet handling (in
5976 the key agreement packet handling we do not want to encrypt
5979 * Implemented the responder side of the key agreement routines
5980 in the client. The client can now bind to specified port and
5981 accept incoming key negotiation. The key material is passed
5982 to the application after the protocol is over.
5984 * Implemented the processing of incoming Key Agreement packet
5985 in the client. Added function silc_client_key_agreement to
5988 * Implemented the intiator side of the key agreement routines
5989 in the client. The client can now initiate key agreement with
5990 another remote client. The key material is passed to the
5991 application after the protocol is over.
5993 * Created client_keyagr.c to include all the key agreement
5996 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5997 SILC_TASK_CALLBACK except that it is not static.
5999 * Created client_notify.c and moved the Notify packet handling
6000 from the client.[ch] into that file.
6002 * Created client_prvmsg.c and moved all private message and
6003 private message key routines from the client.[ch] into that file.
6005 * Create client_channel.c and moved all channel message and
6006 channel private key routines from the client.[ch] into that file.
6008 * Changed silc_client_get_client_by_id_resolve to resolve with
6009 WHOIS command instead of IDENTIFY command, in the file
6010 lib/silclient/idlist.c.
6012 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Implemented the SKE's responder side to the Client library.
6016 * When FAILURE is received to the protocol do not trust it
6017 blindly. Register a timeout to wait whether the remote closes
6018 the connection as it should do it, only after that process the
6019 actual failure. This was changed to both client and server.
6021 * Added client_internal.h to include some of the structures
6022 there instead of client.h in lib/silcclient/.
6024 * Added function silc_task_unregister_by_callback to unregister
6025 timeouts by the callback function.
6027 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Some "Incomplete WHOIS info" errors has been appearing on the
6030 log files. Took away the entry->userinfo check from WHOIS
6031 reply sending. The entry->userinfo is now " " if client did not
6032 provide one. I thought this was fixed earlier but something
6033 is wrong still. Let's see if the error still appears.
6035 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Fixed a minor bug in the login when the channel key is
6038 re-generated in the server. It used to generate the key in
6039 wrong order and thus caused problems in the channel traffic.
6041 * Fixed a minor bug in channel key distsribution after
6042 KICK command. The key was not sent to the router even though
6045 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Added silc_ske_process_key_material_data as generic routine
6048 to process any key material as the SILC protocol dictates. The
6049 function is used by the actual SKE library but can be used by
6050 applications as well. This relates to the private message keys
6051 and the channel private keys since they must be processed the
6052 same way the normal SILC session keys. The protocol dictates
6053 this. Affected files: lib/silcske/silcske.[ch].
6055 Added also silc_ske_free_key_material to free the
6056 SilcSKEKeyMaterial structure.
6058 * Defined silc_cipher_set_key function to set the key for
6059 cipher without using the object's method function. The affected
6060 files: lib/silccrypt/silccipher.[ch].
6062 * Implemented silc silc_client_add_private_message_key,
6063 silc_client_add_private_message_key_ske,
6064 silc_client_del_private_message_key,
6065 silc_client_list_private_message_keys and
6066 silc_client_free_private_message_keys functions in the
6069 Added functions silc_client_send_private_message_key to send
6070 the Private Message Key payload and silc_client_private_message_key
6071 to handle incoming Private Message Key payload.
6073 * Added Cipher field to the Private Message Key payload to set
6074 the cipher to be used. If ignored, the default cipher defined
6075 in the SILC protocol (aes-256-cbc) is used.
6077 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Removed lib/silcclient/ops.h file.
6081 Redefined parts of the SILC Client Library API. Created new
6082 file silcapi.h that deprecates the ops.h file and defines the
6083 published Client Library API. Defined also private message key
6084 API and channel private key API into the file.
6086 This is the file that the application must include from the
6087 SILC Client Library. Other files need not be included by
6088 the application anymore.
6090 * Added new key_agreement client operation callback and also
6091 defined the Key Agreement library API for the application.
6093 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6096 is used by clients to request key negotiation between another
6097 client in the SILC network. If the negotiation is started it
6098 is performed using the SKE protocol. The result of the
6099 negotiation, the secret key material, can be used for example
6100 as private message key.
6102 Implemented the Key Agreement payload into the files
6103 lib/silccore/silauth.[ch].
6105 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Redefined ciphers for the SILC protocol. Added some new ciphers
6108 and defined the key lengths for the algorithms. Changed the
6109 code accordingly. The default key length is now 256 bits.
6111 * Fixed SKE key distribution function silc_ske_process_key_material
6112 when the key length is more than 128 bits. The default key
6113 length in SILC is now 256 bits.
6115 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6116 to indicate unsupported algorithm.
6118 * Renamed rijndael.c to aes.c and all functions as well.
6120 * Fixed a long standing channel key setting bug in client library.
6121 Weird that it has never surfaced before.
6123 * Fixed bug in channel deletion. If the entire channel is removed
6124 then it must also delete the references of the channel entry
6125 from the client's channel list as the client's channel entry and
6126 the channel's client entry share same memory.
6128 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Implemented CONNECT and SHUTDOWN commands in the client.
6132 * Implemented CLOSE command to the client.
6134 * Added the function silc_idlist_find_server_by_name into the
6135 files silcd/idlist.[ch].
6137 Added the function silc_idlist_find_server_by_conn into the
6138 files silcd/idlist.[ch].
6140 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * DIE command was renamed to SHUTDOWN. Updated the both code
6145 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6146 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6148 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6151 * Added function silc_server_create_connection function to create
6152 connection to remote router. My server implementation actually
6153 does not allow router to connect to normal server (it expects
6154 that normal server always initiates the connection to the router)
6155 so the CONNECT command is only good for connecting to another
6158 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6161 or some other client was kicked from the channel.
6163 Implemented the handling of the notify type to both client
6166 Implemented silc_server_send_notify_kicked to send the KICKED
6167 notify. It is used to send it to the server's primary router.
6169 * Implemented the KICK command into server and client.
6171 * Added `query' argument to the silc_idlist_get_client function
6172 to indicate whether to query the client from server or not if
6175 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6176 to indicate that the client is not channel founder.
6180 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Removed the rng context from SilcPacketContext structure and
6183 changed that the packet routine uses the Global RNG API.
6185 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Added support for quit message that client can "leave" on the
6188 channel when it quits the SILC. It is ditributed inside the
6189 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6191 Added silc_server_free_client_data that will take the
6192 signoff message as argument.
6194 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6196 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Updated parts of the protocol specification to keep it up
6201 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6204 payloads in one packet.
6206 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6207 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6208 use now the new List flag.
6210 * Also deprecated the following packet types: REPLACE_ID,
6211 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6213 * Added list support for Notify packet in server.
6215 * Added silc_server_send_notify_channel_change to send the
6216 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6217 the silc_server_send_replace_id.
6219 * Added silc_server_send_notify_nick_change to send the
6220 NICK_CHANGE notify type. Deprecates the function
6221 silc_server_send_replace_id.
6223 * Added silc_server_send_notify_join to send the JOIN notify type.
6224 Deprecates the function silc_server_send_new_channel_user.
6226 * Added silc_server_send_notify_leave to send LEAVE notify type.
6227 Deprecates the function silc_server_send_remove_channel_user.
6229 * Added silc_server_send_notify_cmode and
6230 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6231 types. Deprecates the silc_server_send_set_mode function.
6233 * Added SERVER_SIGNOFF notify type to indicate that server has
6234 quit. This means that all clients on the channel from that
6235 server will drop. This can be also used when netsplit happens.
6237 Deprecated REMOVE_ID packet type since it is not needed anymore
6240 Added silc_server_send_notify_server_signoff to send the
6241 SERVER_SIGNOFF notify type. Deprecates the function
6242 silc_server_send_remove_id.
6244 Added also silc_server_send_notify_signoff to send the
6245 SIGNOFF notify type.
6247 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6248 SILC protocol from this day on. Changed the protocol
6249 specification as well.
6251 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6252 notify type. It is used between routers to notify about
6253 topic changes on a channel.
6255 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6258 * Partly updated the protocol specification to comply with the
6259 changes now made. It is still though a bit outdated.
6261 * The JOIN notify type now takes one extra argument <Channel ID>.
6262 The packet used to be destined to the channel but now the
6263 JOIN type may be sent as list thus it is impossible to
6264 destine it to any specific channel. By adding this argument
6265 it is again possible.
6267 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6269 * Added CREDITS file. The CHANGES and CREDITS file will appear
6270 in the distribution as well.
6272 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6275 types in the server's silcd/packet_receive.c.
6277 * Implemented CMODE and CUMODE to work in router environment.
6279 * Fixed minor encoding and decoding buglet from the
6280 lib/silccore/silcmode.c.
6282 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6285 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6287 * Changed all SilcConfigServer* and silc_config_server* to
6288 SilcServerConfig* and silc_server_config*, respectively.
6291 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Associated the ID (client or server ID) to the Authentication
6294 Payload to avoid any possibility of forging. Updated the
6295 protocol specification and the code accordingly.
6297 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * The RSA key length is now save to the RsaKey context in the
6300 key generation process in lib/silccrypt/rsa.c. The key length
6301 is now used to figure out the maximum size of the block allowed
6302 to be encrypted/signed.
6304 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6305 is equivalent to the silc_mp_mp2bin but does not allocate any
6308 * Changed silc_mp_mp2bin API to take length argument. If it is
6309 non-zero then the buffer is allocated that large. If zero, then
6310 the size is approximated using silc_mp_sizeinbase, which however
6313 * Created Global RNG API which is global RNG that application can
6314 initialize. After initializing, any routine anywhere in the
6315 code (including library) can use RNG without allocating a new
6316 RNG object. This was done to allow this sort of use of the
6317 RNG in code that has no chance to allocate RNG object. All
6318 applications currently allocate this and many routines in the
6319 library use this. Affected file lib/silccrypt/silcrng.[ch].
6321 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6322 it to use the Global RNG API.
6324 * Defined Authentication Payload into protocol specification that
6325 is used during SILC session to authenticate entities. It is
6326 used for example by client to authenticate itself to the server
6327 to obtain server operator privileges.
6329 Implemented this payload into the lib/silccore/silcauth.[ch].
6330 Implemented also routines for public key based authentication
6331 as the new protocol specification dictates.
6333 Moved definitions of different authentication methods from
6334 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6336 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6337 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6338 silc_pkcs_verify_with_hash functions into the file
6339 lib/silccrypt/silcpkcs.[ch].
6341 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * The client entry's userinfo pointer must be always valid.
6344 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6345 will fail since it requires the userinfo. Now, the userinfo
6346 is allocated as "" if actual userinfo does not exist. Actually,
6347 it must exist and it is totally Ok to drop client connections
6348 that does not announce the userinfo. However, we will make
6349 this workaround for now.
6351 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6352 to return the remote port by socket.
6354 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6357 SILC_SERVER_PENDING_EXEC and added an new macro
6358 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6359 data or when error occurs while processing the pending command.
6361 Added new argument `destructor' into silc_server_command_pending
6362 and to the SilcServerCommandPending object. This destructor is
6363 now called after calling the pending callback or if error occurs
6364 immediately. If error occurs the actual pending callback won't
6365 be called at all - only the destructor. The destructor may be
6366 NULL if destructor is not needed.
6368 All this applies for client library code as well. Similar
6369 changes were made there as well for the pending commands.
6371 In the client, the application must now allocate the
6372 SilcClientCommandContext with the silc_client_command_alloc
6375 * Added reference counter to the SilcServerCommandContext. Added
6376 function silc_server_command_alloc and silc_server_command_dup
6379 Same type of functions added to the client library for the same
6382 * Removed the cmd_ident from IDListData away since it is now
6383 global for all connections. It is the command identifier used
6384 in command sending and with pending commands. The affected file
6387 * Added reference counter to the SilcSocketConnection objecet to
6388 indicate the usage count of the object. The object won't be
6389 freed untill the reference counter hits zero. Currently only
6390 server uses this, and client ignores it. The client must be
6391 set to use this too later. The affected files are
6392 lib/silccore/silcsockconn.[ch]. Added also the function
6393 silc_socket_dup to increase the reference counter.
6395 This was mainly added because it is possible that the socket
6396 is removed underneath of pending command or other async
6397 operation. Now it won't be free'd and proper DISCONNECTING
6398 flags, etc. can be set to avoid sending data to connection that
6399 is not valid anymore.
6401 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6402 the connection. After that it sets SILC_SET_DISCONNECTED.
6403 It is, however, possible that the socket data is not still freed.
6404 The silc_server_packet_process now checks that data is not
6405 read or written to connection that is DISCONNECTED. The socket
6406 get's freed when the reference counter hits zero.
6408 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Changed the client operation API: channel_message operation's
6411 `sender' is now the client entry of the sender, not the nickname
6412 and the `channel' is the channel entry, not the channel name.
6414 In the private_message operation the `sender' is now also the
6415 client entry of the sender not the nickname.
6417 Affected file is lib/silcclient/ops.h and all applications
6418 using the client operations.
6420 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Moved the calling of ops->connect() from connect_to_server_final
6423 into receive_new_id functin since that is the point when the
6424 client is actually allowed to send traffic to network. The
6425 affected file is lib/silcclient/client.c.
6427 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6430 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6431 (if needs broadcasting) instead of broadcasting the packets one
6432 by one which would make a burst in the network traffic.
6434 * Added `broadcast' argument to the functions in silcd/server.[ch]
6435 silc_server_create_new_channel[_with_id] to indicate whether
6436 to send New Channel packet to primary router.
6438 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Added new function into the silcd/server.[ch] files:
6441 silc_server_create_new_channel_with_id to create new channel with
6442 already existing Channel ID.
6444 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6445 lib/silccore/silcpacket.h. This packet is used t send list of
6446 Set Mode payloads inside one packet. Server uses this to set
6447 the modes for the channels and clients on those channels, that it
6448 announced to the router when it connected to it. The protocol
6449 specification has been updated accordingly.
6451 * The silc_server_new_channel did not handle the packet coming
6452 from normal server as it normally does not send that. However,
6453 when it announces its channels it does send it. Implemented
6454 the support for that.
6456 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6457 into the file lib/silccore/id.h.
6459 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Fixed memory leaks in the functions silc_idlist_del_client,
6462 silc_idlist_del_channel and silc_idlist_del_server in the file
6463 silcd/idlist.c. All of those leaked like a sieve.
6465 * Fixed some small memory leaks in the client's function
6466 silc_client_notify_by_server.
6468 * Added functions into silcd/server.c: silc_server_announce_clients,
6469 silc_server_announce_channels and silc_server_announce_server.
6470 These functions are used by normal and router server to announce
6471 to its primary router about clients, channels and servers (when
6472 router) that we own. This is done after we've connected to the
6475 These functions effectively implements the following packet types:
6476 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6477 and SILC_PACKET_NEW_ID_LIST.
6479 * Added new functions into the silcd/packet_receive.[ch]:
6480 silc_server_new_id_list, silc_server_new_channel_list and
6481 silc_server_new_channel_user_list to handle the incoming
6482 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6484 * Added support of changing Channel ID in the function
6485 silc_server_replace_id. If the server that announces a channel
6486 to the router already exists in the router (with same name but
6487 with different Channel ID), router is responsible to send
6488 Replace ID packet to the server and force the server to change
6489 the Channel ID to the one router has.
6491 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6492 client that the Channel ID has been changed by the router. The
6493 normal server sends this to the client. Client must start using
6494 the new Channel ID as the channel's ID.
6496 Implemented handling of this new type into lib/silcclient/client.c
6497 into the function silc_client_notify_by_server.
6499 * Added new function silc_idlist_replace_channel_id into the files
6500 silcd/idlist.[ch] to replace the Channel ID.
6502 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Call silc_server_command_identify_check always when processing
6505 the IDENTIFY command in silcd/command.c
6507 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6509 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6510 send keepalive packets. The packet can be sent by clients,
6511 servers and routers.
6513 Added function silc_socket_set_heartbeat into the file
6514 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6515 If not set, the heartbeat is not performed. The actual
6516 heartbeat is implemented in the low level socket connection
6517 library. However, application is responsible of actually
6520 Added silc_server_send_heartbeat to send the actual heartbeat
6521 packet into silcd/packet_send.[ch]. Server now performs
6522 keepalive with all connections.
6524 * Added silc_task_get_first function into lib/silcutil/silctask.c
6525 to return the timeout task with shortest timeout. There was a bug
6526 in task unregistration that caused problems. TODO has been
6527 updated to include that task system must be rewritten.
6529 * The client library will now resolve the client information when
6530 receiving JOIN notify from server for client that we know but
6531 have incomplete information.
6533 * Rewrote parts of silc_server_remove_from_channels and
6534 silc_server_remove_from_one_channel as they did not remove the
6535 channel in some circumstances even though they should've.
6537 * Encryption problem encountered in server:
6539 The LEAVE command used to send the Channel Key packet to the
6540 router immediately after generating it. However, the code
6541 had earlier sent Remove Channel user packet but not immediately,
6542 ie. it was put to queue. The order of packets in the router
6543 was that Channel Key packet was first and Remove Channel User
6544 packet was second, even though they were encrypted in the
6545 reverse order. For this reason, MAC check failed. Now, this
6546 is fixed by not sending the Channel Key packet immediately but
6547 putting it to queue. However, this is more fundamental problem:
6548 packets that are in queue should actually not be encrypted
6549 because packets that are sent immediately gets encrypted
6550 actually with wrong IV (and thus MAC check fails). So, packets
6551 that are in queue should be encrypted when they are sent to
6552 the wire and not when they put to the queue.
6554 However, the problem is that the current system has not been
6555 designed to work that way. Instead, the packet is encrypted
6556 as soon as possible and left to the queue. The queue is then
6557 just purged into wire. There won't be any fixes for this
6558 any time soon. So, the current semantic for packet sending
6561 o If you send packet to remote host and do not force the send
6562 (the packet will be in queue) then all subsequent packets to the
6563 same remote host must also be put to the queue. Only after the
6564 queue has been purged is it safe again to force the packet
6567 o If you send all packets immediately then it safe to send
6568 any of subsequent packets through the queue, however, after
6569 the first packet is put to queue then any subsequent packets
6570 must also be put to the queue.
6572 Follow these rules and everything works fine.
6574 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Added new function silc_server_remove_clients_by_server to
6577 remove all client entries from ID list when the server connection
6578 is lost. In this case it is also important to invalidate all
6579 client entires as they hold the invalid server entry. This
6580 fixes fatal bug when server has lost connection and will reconnect
6583 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Made some sanity checks to silc_server_daemonise like to check
6586 whether the requested user and group actually exists.
6588 * Added sanity check to SKE's silc_ske_responder_finish to check
6589 that the public and private key actually is valid.
6591 * Invalidate the client's nickname when receiving Replace ID
6592 packet and the Client ID is being replaced. This means that the
6593 server will query the nickname if someone needs it (client)
6596 * Sort the ID Cache in client library when the ID Cache data
6597 has changed (needs sorting).
6599 * Do not allow for SILC client to create several connections to
6600 several servers. The client does not support windows right now
6601 and generating multiple connections causes weird behaviour.
6603 Irssi-silc client does support windows and can handle several
6604 connections without problems, see: www.irssi.org and SILC plugin.
6606 * Fixed some places where client was added to the IDList. The
6607 rule of thumb is following (in order to get everything right):
6608 If the client is directly connected local client then the
6609 `connection' argument must be set and `router' argument must be
6610 NULL to silc_idlist_add_client function. If the client is not
6611 directly connected client then the `router' argument must
6612 bet set and the `connection' argument must be NULL to the
6613 silc_idlist_add_client function.
6615 * The funtion silc_server_packet_send_local_channel actually did
6616 not check whether the client was locally connected or not. It
6617 does that now. Fixed a bug related to LEAVE command.
6619 * Fixed Remove Channel User payload parsing bug in server's
6620 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6622 * The server's silc_server_save_channel_key now checks also the
6623 global ID list for the channel as it might not be in the local
6624 list. Fixed a bug related to LEAVE command.
6626 * Is this the end of the [<unknown>] buglet that has been lurking
6627 around for a long time? A little for loop fix in server's
6628 silc_server_command_whois_parse that is used by both IDENTIFY
6629 and WHOIS command. At least, this was a clear bug and a cause
6630 of one type of [<unknown>] buglet.
6632 * WHOIS and IDENTIFY commands call the function
6633 silc_server_command_[whois/identify]_check function even if
6634 we are not router server.
6636 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Added --with-gmp configuration option. If set the GMP
6639 is always compiled in the SILC source tree. If not set then
6640 it is checked whether the system has the GMP3 installed. If
6641 it has then the GMP won't be compiled (the system's headers
6642 and library is used), if it doesn't have it then the GMP is
6643 compiled in the SILC source tree.
6645 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Changed RSA private exponent generation to what PKCS #1
6648 suggests. We try to find the smallest possible d by doing
6649 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6650 not security fix but optimization.
6652 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Added new config entry [Identity] to fork the server and run
6655 it as specific user and group. A patch from Bostik.
6657 * Imported Dotconf configuration library into lib/dotconf.
6658 This will be used to create the SILC configuration files later.
6659 It will appear in the distsribution after this commit.
6661 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * A big code auditing weekend happening. Auditing code for
6664 obvious mistakes, bugs and errors. Also, removing any code
6667 Removed files for being obsolete:
6669 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6670 inline in the file lib/silcutil/silcbuffer.h)
6672 o lib/silcutil/silcbufutil.c (the header has inline versions)
6674 Changed code to fix possible error conditions:
6676 o The buffer formatting routines now check that the destination
6677 buffer really has enough space to add the data. This applies for
6678 both buffer formatting and unformatting
6679 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6680 unformatting was changed to accomodate following rules:
6681 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6682 sent to the function while XXX_*STRING will not allocate or copy
6683 the data into the buffer. Instead it sets the pointer from the
6684 buffer into the pointer sent as argument (XXX_*STRING used to
6685 require that the pointer must be allocated already). This change
6686 makes this whole thing a bit more consistent and more optimized
6687 (note that the data returned in the unformatting with XXX_*STRING
6688 must not be freed now). The routines return now -1 on error.
6690 o Tried to find all code that use buffer_format and buffer_unformat
6691 and added return value checking to prevent formatting and
6692 especially unformatting errors and possible subsequent fatal
6695 o Changed ske->x and ske->KEY to mallocated pointers in
6696 lib/silcske/silcske.h. Fixed possible data and memory leak.
6698 o Added return value checking to all *_parse* functions. Fixed
6699 many memory leaks as well.
6701 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6702 so that buffer overflows would not happen. All code now also
6703 checks the return value as it can fail.
6705 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Added reconnection support to server if the normal server looses
6708 its connection to the router (for example if router is rebooted).
6709 The server performs normal reconnection strategy implemented
6710 to the server. Affected file silcd/server.c.
6712 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added new packet type SILC_PACKET_SET_MODE that is used to
6715 distribute the information about changed modes (for clients,
6716 channels and clients channel modes) to all routers in the
6717 network. Updated the protocol specification accordingly.
6719 Added functions into silcd/packet_send.c and
6720 silcd/packet_receive.c: silc_server_send_set_mode,
6721 silc_server_set_mode.
6723 Added new files silcmode.[ch] into lib/silccore that implements
6724 the encoding and decoding of Set Mode Payload. Added new type
6725 SilcSetModePayload. Moved the definitions of different modes
6726 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6728 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Oops, a little mistake in server's connection authentication
6731 protocol. The protocol is not ended with FAILURE but with
6732 SUCCESS if the authentication is Ok. :) Affected file is
6735 * Implemented NICK_CHANGE notify handling in server in the file
6736 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6737 the local clients on the channel. After the changing nickname
6738 in router environment snhould work and the [<unknown>] nickname
6739 should appear no more.
6741 The silc_server_replace_id function that receives the Replace ID
6742 payload now sends the NICK_CHANGE notify type also in the file
6743 silcd/packet_receive.c
6745 * Changed WHOIS and IDENTIFY command to support the maximum amount
6746 of arguments defined in protocol specs (3328 arguments). This
6747 fixed a bug that caused problems when there were more than three
6750 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Added extra parameter, command identifier, to the
6753 silc_client_send_command so that explicit command identifier
6756 Changed that ID list routines uses specific command identifier
6757 when sending WHOIS/IDENTIFY requests to the server so that they
6758 can be identified when the reply comes back.
6760 Affected files lib/silcclient/command.[ch],
6761 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6763 * Added `sender' argument to silc_server_packet_send_to_channel
6764 to indicaet the sender who originally sent the packet to us
6765 that we are now re-sending. Ignored if NULL. Affected file
6766 silcd/packet_send.[ch].
6768 * Added some server statistics support in silcd/server_internal.h
6769 SilcServerStatistics structure and around the server code. Also
6770 send some nice statistics information when client is connecting
6773 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * Fixed channel ID decoding in server's JOIN command reply in
6776 silcd/command_reply.c
6778 * Fixed braodcasting of replace ID payload to not to send it if
6779 we are standalone server in silcd/packet_receive.c.
6781 * Fixed all channel message sending routines to not to send
6782 packets to clients that has router set, since they are routed
6783 separately in the same function earlier. Affects file
6784 silcd/packet_send.c and all channel packet sending functions.
6786 * In USERS reply, res_argv[i] are not allocated, the table
6787 is allocated. Thus changed that free the table, not its
6790 * In server's whois_check and identify_check if the client is
6791 locally connected do not send any WHOIS commands - they are not
6794 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Fixed some minor bugs in client when sending WHOIS command. The
6797 arguments was in wrong order.
6799 * Removed statis function add_to_channel from server in
6800 silcd/command.c that was previously used with the joining but
6803 * Tested USERS command in router environment successfully with two
6804 routers, two servers and two clients.
6806 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Reorganized the USERS command and command reply in client library
6809 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6810 When the command is given by user we register a pending command
6811 callback that will reprocess the command after the reply has been
6812 received from the server. When reprocessing the packet we then
6813 display the information. Thus, the USERS information is displayed
6814 now in the command callback instead of in the command reply
6815 callback. The processing of the command is same as previously
6816 when server has sent the command reply in the JOINing process.
6818 * Added to USERS command in silcd/command_reply.c to join the client,
6819 we didn't use to know about, to the channel after we've created
6820 a client entry for it. Also, for clienet we did know already still
6821 check whether it is on the channel or not and add it if not.
6823 * Removed silc_server_command_join_notify as the function and its
6826 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Changed the client's pending command handling to the same as the
6829 server's pending command handling. It is also now possible to
6830 execute command reply functions from other command reply
6831 function as the function callbacks for commands and command
6832 replies are one and same. The pending commands are not static
6833 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6834 in client connection context. Thus, pending commands are server
6835 connection specific as it is convenient.
6837 Changed the function silc_client_command_pending and
6838 silc_client_command_pending_del and added new function
6839 silc_client_command_pending_check. Removed the
6840 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6843 * Added cmd_ident, current command identifier, to the client
6844 connection context in lib/silcclient/client.h to keep track on
6845 command identifiers used in command sending. Client's command reply
6846 function handling now supports the mandatory command identifiers.
6848 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6849 funtions in client to fully support pending command callbacks.
6851 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6852 as one of the arguments to the application in the command reply
6855 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6856 before first releasing SILC but came back. Now it is removed again
6857 and should come back nomore. The FORWARDED flag was used only
6858 by the JOINing procedure by forwarding the command packet to router.
6859 Now, the JOINing procedure has been changed to more generic (due
6860 to various router environment issues) and FORWARDED is not needed
6861 anymore for anything. The protocol specification is yet to be
6864 Now, removed silc_server_packet_forward from server and the flag
6865 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6867 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Renamed NAMES command to USERS command. The NAMES was named that
6870 due to historical reasons. Now it is renamed. Also, rewrote
6871 parts of the USERS command. The nickname list is not sent anymore
6872 by the server. Only Client ID and mode lists are sent in the USERS
6873 command. Changed this also to the protocol specification.
6875 The client now resolves the names and stuff after it receives
6876 the USERS list from the server when joining to the channel.
6878 * WHOIS and IDENTIFY commands has been changed to support multiple
6879 Client ID's per command. One can now search for multiple users
6880 in the network by sending only one WHOIS or IDENTIFY command.
6881 Changed the code and the protocol specifications.
6883 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6884 uses silc_server_command_whois_parse to parse the request. */
6886 * If normal server, do not parse the WHOIS and IDENTIFY requests
6887 before sending it to the router. Saves some time.
6889 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Fixed JOIN command on client library. Wrong number of arguments
6892 used to crash the client.
6894 * Added silc_server_channel_has_global function to check whether
6895 channel has global users or not.
6897 * Added silc_server_channel_has_local function to check whether channel
6898 has locally connected clients on the channel.
6900 * The silc_server_remove_from_one_channel now checks whether the
6901 channel has global users or not after given client was removed from
6902 the channel. It also checks whether the channel has local clients
6903 on the channel anymore. If it does not have then the channel entry
6904 is removed as it is not needed anymore.
6906 * The silc_server_notify now checks on JOIN notify whether the joining
6907 client is one of locally connected or global. If it is global then
6908 the channel has now global users on the channel and that is marked
6909 to the channel entry. Also, it now saves the global client to
6910 global list who is joining and JOINs it to the channel. This is
6911 for normal server, that is.
6913 Changed silc_server_send_notify_on_channel,
6914 silc_server_packet_relay_to_channel and
6915 silc_server_packet_send_to_channel check if we are normal server
6916 and client has router set (ie. global client) do not send the
6917 message to that client, as it is already routed to our router.
6919 * Implemented LEAVE notify type handling in silc_server_notify
6922 * Tested LEAVE command in router environment successfully. Tested
6923 with two routers, two servers and two clients.
6927 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6929 * Implemented SIGNOFF notify type handling in silc_server_notify
6932 * silc_server_remove_id now removes the client entry from all channels
6933 it has joined and thusly sends SIGNOFF notify type.
6935 * Rewrote the NAMES list generation in server by removing two excess
6936 loops. The lists are created now inside one loop.
6938 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * silc_server_remove_channel_user checks now also global list
6941 for channel and client.
6943 * silc_server_new_channel_user checks now both local and global
6944 list for channel and client. Fixed a bug in client id decoding.
6945 Used to decode wrong buffer.
6947 * silc_server_channel_message checks now both local and global
6948 list for channel entry.
6950 * Tested channel joining (hence JOIN) in router environment
6951 successfully. Tested with two routers, two servers and two
6954 * Tested channel message sending in router environment successfully.
6956 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6958 * Added silc_server_save_channel_key into server.[ch] to save the
6959 received channel key in Channel Key payload processing. It is
6960 also used in JOIN command reply handling.
6962 Equivalent function silc_client_save_channel_key added into
6963 client.[ch] into client library.
6965 * Changed JOIN command reply to send information whether the channel
6966 was created or not (is existing already) and the channel key
6967 payload. Changed protocol specs accordingly.
6969 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6970 the request was sent by ID and not by nickname. Crashed on
6973 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6975 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6976 now correctly save the received data.
6978 * silc_server_free_sock_user_data now notifies routers in the
6979 network about entities leaving the network.
6981 At the same time implemented functions silc_server_remove_id
6982 and silc_server_send_remove_id to receive and send REMOVE_ID
6983 packets. The packet is used to notify routers in the network
6984 about leaving entities. The ID removed will become invalid in
6987 * Added function silc_idlist_del_server into server. Removes and
6988 free's server entry from ID list.
6990 * silc_server_private_message function now checks, if we are router,
6991 that the destination ID really is valid ID, naturally.
6993 * In router when NEW_ID packet is received (for new client) the
6994 hash of the Client ID is saved in the ID Cache but the
6995 client->nickname is set to NULL, instead of putting the hash
6998 IDENTIFY command now also checks that client->nickname must be
6999 valid. If it is not if will request the data from the server who
7000 owns the client. Added new function
7001 silc_server_command_identify_check.
7003 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7004 to set the command to already allocated Command Payload.
7006 * Tested private message sending in router environment with two
7007 routers, two servers and two clients. Fixed minor bugs and now
7010 * Fixed segfault from client's NAMES command. Used to crash if
7013 * Forwarded packets must not be routed even if it is not destined
7014 to the receiver. Changed server code comply with this.
7016 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Added `require_reverse_mapping' boolean value to ServerParams
7019 structure. If TRUE (not default) the server will require that
7020 the connecting host has fully qualified domain name.
7022 If the reverse mapping is not required and hostname could not be
7023 found the IP address is used as hostname.
7025 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Implemented version string checking to both client and server.
7028 The check is incomplete currently due to the abnormal version
7029 strings used in development version of SILC.
7031 * Changed all command functions in server to use the new
7034 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Changed char *data to unsigned char *data in ID Cache system to
7037 support binary data as ID Cache data. Changed code to support
7038 binary data in lib/silccore/idcache.c.
7040 * Renamed silc_server_packet_relay_command_reply to
7041 silc_server_command_reply as it is normal packet receiving
7042 function. Rewrote the function to accept command replys for
7043 servers and not only for clients.
7045 * Mark remote router always as registered server if we are connecting
7046 to it. Otherwise, commands sent by the router to us are ignored.
7048 * All ID List find routines now returns the ID Cache Entry pointer
7049 as well if requested.
7051 * WHOIS command works now in router environment, tested with two
7052 routers, two servers and two clients.
7054 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7055 in router environment (as it is almost equivalent to WHOIS) but
7056 hasn't been tested thoroughly. Added new functions:
7058 silc_server_command_identify_parse
7059 silc_server_command_identify_send_reply
7060 silc_server_command_identify_from_client
7061 silc_server_command_identify_from_server
7063 * Disabled route cache adding because adding two different ID's with
7064 same IP replaces the old cache entry thus giving wrong route.
7065 The entry->router->connection is always the fastest route anyway
7066 so route cache may not be needed. Of course, new routes maybe
7067 established after receiving the ID when the entry->router->connection
7068 might not be anymore the most optimal.
7070 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * Add route cache for received ID for fast routing.
7074 * Added silc_server_packet_route to route received packet on router
7075 that is not destined to us.
7077 * Renamed silc_server_get_route to silc_server_route_get.
7079 * Added id_string and id_string_len fields into SilcServer to
7080 include encoded ServerID for fast comparing without excess
7081 encoding of the ID's.
7083 * Cleaned up WHOIS command on server side. Added following static
7086 silc_server_command_whois_parse
7087 silc_server_command_whois_check
7088 silc_server_command_whois_send_reply
7089 silc_server_command_whois_from_client
7090 silc_server_command_whois_from_server
7092 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7093 arguments in command replies. All command functions should be
7094 updated to use this macro.
7096 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Minor typo fixes on command reply handling on server.
7100 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Added silc_server_command_add_to_channel internal routine to add
7103 the client to the channel after router has created the channel and
7104 sent command reply to the server.
7106 * Added generic silc_server_send_command to send any command from
7109 * Use static buffer with ID rendering instead of duplicating data.
7111 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * Fixed a channel user mode bug when joining to a channel server gave
7114 everybody channel founder rights, oops.
7116 * We mark ourselves as the router of the incoming server connection
7117 if we are router ourselves. This way we can check in some packet
7118 sending functions whether it is locally connected server. For
7119 incoming router connections we put NULL.
7121 * For router sending packets locally means now always sending the
7122 packet cell wide; to local clients and local servers. For normal
7123 server sending packet locally means sending it to only local
7126 * Fixed the JOIN command to really work in router environment. If the
7127 channel is created it is always created by the router. Router is
7128 also responsible of making the initial joining to the channel,
7129 sending JOIN notify to the sending server and distributing
7130 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7131 does not exist server doesn't do anything else but forward the
7132 command to the router which performs everything.
7134 * Added silc_server_send_channel_key function to send the Channel Key
7137 * Added silc_server_create_channel_key to create new channel key. The
7138 channel key is now re-generated everytime someone joins or leaves
7139 a channel, as protocol dictates. Note: channel->key_len is the
7142 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7145 packet_receive.[ch] to separate packet sending and receiving
7146 routines. The server.[ch] now includes everything else including
7147 actual packet processing (writing and reading data) and other
7150 Renamed silc_server_private_message_send_internal to
7151 silc_server_send_private_message. The routine is still though
7152 used only to relay private messages as server does not send
7153 private messages itself.
7155 Renamed silc_server_new_channel to silc_server_create_new_channel
7156 and added new function sicl_server_new_channel that handles the
7157 incoming New Channel packet. Added also new sending function
7158 silc_server_send_new_channel to send New Channel Payload.
7160 * Added new function silc_server_notify to process incoming notify
7161 packet to the server/router. Server may then relay the notify
7162 to clients if needed.
7164 * Added new function silc_server_new_channel_user to process incoming
7165 New Channel User packet. Router will redistribute the packet and
7166 send JOIN notify to its local clients and locally connected servers
7167 if needed. Normal server will send JOIN notify to its local client
7168 on same channel when received this packet. Added also corresponding
7169 sending function silc_server_send_new_channel_user to sent the
7172 * Added boolean route argument to send_notif_to_channel and
7173 packet_send_to_channel functions to attempt to route the packet
7174 if it is TRUE and send only locally if it is FALSE.
7176 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * silc_server_replace_id now broadcasts the received replace ID
7179 packet if it is not broadcast packet already. The router must
7180 broadcast to inform other routers about changed ID.
7182 * Added backpointer to server's router into SilcServer context in
7183 silcd/server_internal.h.
7185 * Fixed silc_server_packet_broadcast to send correct broadcast
7188 * The channel key is now distributed to the local client as soon
7189 as it is received from the router (in router environment) so that
7190 no other packet may be sent for the channel until client has
7193 * silc_server_remove_channel_user now broadcasts the received
7194 Remove Channel User packet if it is not broadcast packet already.
7195 The router must broadcast to inform other routers about removed
7198 * Added users field into SilcPacketContext that is a reference count
7199 of the context. One can increase the reference count by calling
7200 silc_packet_context_dup which is now changed to just increase the
7201 reference count instead of duplicating the data. The reference
7202 count is decresed by calling silc_packet_context_free that will
7203 free the data after the reference count hits zero.
7205 For now on the packet context and everything allocated into it
7206 (including the raw packet from network) must be freed by calling
7207 the new silc_packet_context_free function. Added also new function
7208 silc_packet_context_alloc that must be used now to allocate the
7209 context. This also means that if a routine is asynchronous from
7210 silc_[client/server]_packet_parse_type the packet context must
7211 be duplicated by calling silc_packet_context_dup. Otherwise it
7212 gets free'd after silc_[client/server]_packet_parse_type returns.
7213 Also, one must remember that if packet is duplicated then its
7214 reference count must be decresed by calling the free function as
7215 many times as it was duplicated.
7217 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7218 from both client and server.
7220 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Made joining to a channel working in router environment.
7224 * Cleaned up JOIN command on server side and create function
7225 silc_server_command_join_channel internal routine to make the
7228 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Changed silc_command_pending list to SilcDList. Also, added
7231 `ident' field to SilcServerCommandPending structure to identify
7232 the reply and to call correct callback.
7234 Added silc_server_command_pending_check function to replace the
7235 corresnponding macro. The silc_command_pending list is not
7238 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7239 to set identifier to previously allocated Command Payload. It
7240 is used to set identifier for command when resending Command
7243 * Added silc_command_payload_encode_payload to encode Command
7244 Payload buffer from SilcCommandPayload structure.
7246 * Added silc_argument_payload_encode_payload to encode Argument
7247 payload buffer from SilcArgumentPayload structure.
7249 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Changed WHOIS command to support router connection on server side.
7252 The whois request is always sent to router unless the server is
7253 standalone server. After server has received the reply from the
7254 router will it send the reply to the client.
7256 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7257 broadcast received broadcast packet. The function is used only
7258 by router. The broadcast packet is always sent to the router's
7261 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7262 render given ID to printable string, for log files for example.
7264 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Made basic router to router connections working. At least they
7267 can now connect to each other but nothing really works the way
7268 they are supposed - yet.
7270 * Added new initiator token to RouterConnection configuration
7271 file in silcd/serverconfig.[ch]. It is used to tell whether we
7272 are the initiator to the remote router or whether we'll expect
7273 the other end to connect.
7275 * Moved registering of listener task to silc_server_init, hence
7276 the server starts listenning as soon as it is run, even if it
7277 does not have connections to other routers. Let's see how well
7280 * Changed default connection retry timeouts for more suitable in
7283 * Removed cipher and such arguments from silc_idlist_add_client
7284 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7285 Added new function silc_idlist_add_data to add the keys and stuff
7288 * Added SilcIDListData structure and added it to SilcClientEntry
7289 and SilcServerEntry as their first field in the structure. This
7290 way we can explicitly cast the ID entries to the SilcIDListData
7291 structure and get common data for the entries. In past, we had
7292 to first check what type of connection it is and then cast it to
7293 correct ID entry type. Now, we can directly cast the opaque
7294 pointer to the SilcIDListData (no matter what ID entry it actually
7295 is) and get the data needed.
7297 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7299 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7300 in some circumstances even if threre were timeout tasks, though not
7301 IO tasks, but tasks anyway. Now fixed.
7303 * Defined SilcServerConnection structure to hold connection specific
7304 stuff about directly connected servers and routers. The definition
7305 is currently in silcd/server_internal.h. I thought about having
7306 a bit more important role fro this struct but for now it is used
7307 only when connecting to other server (or router actually).
7309 * Added connecting retry support in server when connecting to
7310 router(s). The retry feature implement exponential backoff
7311 algorithm. Also, added SilcServerParams structure to hold default
7312 parameters for server. For now, it include these retry settings
7313 and are hard coded. After server is moded to be as Silc Server
7314 Library this structure will be more important.
7316 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7318 * Changed client librarys channel->clients table to SilcList and
7319 changed code accordingly.
7321 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7323 * Changed client's channel table to SilcList and changed code
7324 accordingly. Also changed SilcChannelClientEntry to include back-
7325 pointer to the channel so that client entry can use that structure
7326 as list as well and we have fast cross-reference to the channel.
7327 This change dramatically decreased the complexity of channel
7328 handling with client entry and vice versa (removed one extra
7329 loop when searching for channel entry from many functions).
7331 * Changed server->sim from table to SilcDList and changed code
7334 * NAMES command can now be used from user interface. It will show
7335 the user list on the channel, neatly.
7337 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7338 Code now saves realname of the user if it becomes available.
7340 * Renamed configure.in to configure.in.pre and made ./prepare
7341 script to automatically add correct version string to
7342 configure.in which it creates from configure.in.pre.
7344 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7346 * NAMES command reply now shows users mode with the nickname when
7349 * Moved silc_client_ch[u]mode[_char] functions from
7350 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7351 place sucks, they are utility functions and should be in some
7354 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7356 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7359 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7363 * Added TRQ (efficient deque and list library) into lib/trq. This is
7364 a very good list library that is currently used in the SILC. Defined
7365 SilcList API over the library because I didn't like the API very
7366 much. See lib/trq/silclist.h for the API and examples of how to
7367 use the API. Fixed various places in the code to use the new
7368 SilcList API. The SilcList is meant for lists that has a structure
7369 already defined as a list. It is not suitable to add just some
7370 context to the list (in TRQ, the context is the list actually).
7372 So, I defined SilcDList that can be used for the purpose where
7373 predefined list structure does not exit. This can be used as
7374 such list. Now some context just can be added to the SilcDList.
7375 Currently this list is not used in the SILC just yet, though there
7376 are a lot places where this can replace dynamically allocated
7377 tables and I will fix these places, later, to use SilcDList.
7378 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7379 and use TRQ internally).
7381 Also fixed some annoying warning messages that the original TRQ
7382 code generated. Also minor changes to TRQ's Makefile.in.
7384 * Added support for querying by Client ID to both WHOIS and
7385 IDENTIFY commands into server, as required by the protocol.
7387 * Removed method function pointers from SilcBuffer structure. They
7388 weren't used to anything and just increased the context size for
7389 no good reason. This change also made silc_buffer_alloc and
7390 silc_buffer_free functions inline functions.
7392 * Disabled command flooding detection support until it's fixed so
7393 that it accepts commands in but does not execute them more than once
7396 * Added silc_net_localhost(), to return local hostname, into
7397 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7398 that must be initialized before calling silc_client_init.
7400 * Added new function: silc_server_send_notify_on_channels to send
7401 notify messages to all channels client has joined. It is assured
7402 that the message is sent only once per client.
7404 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7405 lib/silcutil/silcutil.[ch] as silc_format function. The new
7406 function is generic and is used by server as well, not only by
7407 the logging routines.
7409 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7410 the provided version string was not acceptable. Added new function:
7411 silc_ske_check_version into lib/silcske/silcske.h. The function
7412 must be implemented by the application (client or server) and it
7413 does not reside in the SKE library. The function checks the version
7414 string remote end sent.
7416 * Added back pointers (to opaque context and to SilcSocketConnection)
7417 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7419 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7420 duplicate packet context structure.
7422 * Changed `notify' client operation to send same arguments as client
7423 receives from server except for ID's. ID's are mapped to correct
7424 ID entry and that is returned. Also, if channel entry is not sent
7425 by server but the notify is for channel the channel entry is sent
7426 to application (otherwise application doesn't know that it is for
7427 channel (library gets it from packet's Destination ID)).
7429 * Added silc_client_remove_from_channels into client library to
7430 remove a client from all channels it has joined to. Used when
7431 received SIGNOFF notify from server. Added also new function
7432 silc_client_replace_from_channels to replace old ID entry with
7433 new ID entry on all channels. Used when received NICK_CHANGE
7436 * Fixed ID Cache list handling in silc_idlist_get_client in
7437 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7438 to get (or query) client by ID.
7440 * Updated TODO list.
7442 * Added connection authentication status message defined by the
7443 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7444 support for these into the code in client and server side.
7446 * Added generic function silc_client_send_command to send any command
7447 with variable argument list. Application should use this function
7448 to send commands if the command functions provided by the library
7449 does not suite for the application's user interface needs.
7451 * Added new `failure' client operation. Application is notified about
7452 received failure packet if client is executing a protocol. In this
7453 case the protocol's execution has failed.
7455 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7456 is required by the protocol.
7458 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7459 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7462 * Added status flag to SilcSKE object to indicate realtime status
7463 of the SKE protocol.
7465 * Application receives now exactly same command reply arguments as
7466 the library receives from server. However, if ID is received the
7467 corresponding ID entry is returned to the application (eg. Client
7468 ID is mapped to correct SilcClientEntry entry and that is returned).
7469 Changed command_reply client operation due to this change.
7471 * Changed all ID's in commands and in command replys as ID Payloads.
7472 Change affected both client and server side codes.
7474 All ID's sent in SILC network (with execption of ID's in SILC
7475 Packet header) are sent in ID Payload to support variable length
7478 * Server now notifies nick changes and notifies all clients on
7479 the channels about the new nickname (about the new Client ID,
7482 * Implemented CMODE command to change channel modes. Supports all
7483 channel modes defined by the protocol specs except ban and invite
7484 lists. (Also, private channel key mode is supported but support for
7485 setting private channel key in client is missing, thus, this mode
7486 has no effect on client side (except that server requires that the
7487 client uses private channel key and normal channel traffic does not
7490 Also, invite mode works per se, but INVITE command does not work
7491 yet correctly, so you can set channel as invite only channel but
7492 inviting clients to the channel does not work (it is yet to be
7493 thought what's the best way to do it).
7495 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7496 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7497 Implemented CUMODE command to change user's mode on the channel.
7498 Supports all modes defined by the protocol specs.
7500 * Added NAMES command reply to return users modes on the channel.
7502 * Removed unnecessary and slow ciphers from lib/silccrypt.
7504 * Set SO_KEEPALIVE option to connection sockets by default.
7506 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7508 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7509 redefined the Notify Payload into protocol specs.
7511 * Added silc_id_payload_parse_id to get ID directly from raw
7514 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7516 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7517 accept searching by Client ID as well.
7519 * Added support for LEAVE and SIGNOFF notify types in client library.
7521 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7522 to parse ID Payload from raw data.
7524 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Added flags parameter into silc_ske_assemble_security_properties
7527 function in lib/silcske/silcske.[ch].
7529 * Changed notify client operation to fit better for notify messages
7530 sent by server. The notify payload received from server is now
7531 passed to the application (after parsing it to SilcNotifyPayload).
7532 It is application's responsibility to retrieve the arguments
7533 from the payload and show the message the way it wants. The message
7534 sent by server is implementation specific.
7536 * Changed public keys to comply with the protocol specification.
7537 Old public keys are not supported anymore and are not compatible.
7539 * Removed nickname from Channel Payload as the latest draft removed
7540 it. The client must resolve the nickname from the NAMES command
7541 reply received when it joined the channel.
7543 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7545 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Fixed some errors in protocol specification drafts.
7549 * Created lib/silccore/silcnotify.c to implement Notify Payload
7550 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7551 generic payloads described by protocol specifications. The file
7552 includes implementations for ID Payload and Argument Payload.
7554 * Changed Command Payload implementation to use the new Argument
7555 Payload. Changed command_xxxx_payload to command_payload_xxxx
7556 to comply with SILC coding conventions.
7558 * Added suppport for Argument Payload handling in Notify Payload
7559 implementation as protocol requires it. Added the new support
7560 into server and client lib as well.
7562 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7564 * Added support for multiple nicknames on same channel. [n] is
7565 added locally to the nickname if there are more than one same
7566 nicknames on the channel.
7568 * Server now sends all nicknames that matched WHOIS request.
7569 Client also shows the list received from server.
7571 * Added TOPIC command to client side. User can now set and show
7572 current topic on channel.
7574 * Added MOTD command to client and server. Also, server sends the
7575 motd when client connects to the server.
7577 * Changed version strings to comply ISO 8601.
7579 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7581 * Fixed protocol error handling in client library. It should now
7582 cope even if the SKE fails for some reason.
7584 * Made new protocol specification drafts for submitting to IETF.
7586 * Implemented TOPIC command to server in silcd/command.c.
7588 * Added two new notify types into lib/silccore/silcnotify.h:
7589 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7590 notify nickname change and topic setting/change on a channel.
7592 * API change of command_reply operation in client library. The
7593 application gets now the status type received from server as well.
7595 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7599 * Cras fixed and optimized the packet handling even further and
7600 it should work now. Minor change to the prototype of function
7601 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7603 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7605 * Added new function into lib/silcutil/silcschedule.[ch]:
7606 silc_schedule_with_fd to select() a specified fd. The function
7607 returns after timeout expires or data arrives or goes. The
7608 function is used by packet routines to wait that all data is
7609 received from network.
7611 * Fixed data reading from network in lib/silccore/silcpacket.c.
7612 The code now assures that all data is read from the fd and then
7613 continues packet processing. This was a bug fix since the code
7614 used to drop some data in some circumstances.
7616 * Added new function into lib/silcclient/client.[ch]:
7617 silc_client_start_key_exchange to start key exchange after
7618 connection has been established to server. The code internally
7619 now uses this funtion but its main purpose was to provide it
7620 for applications that perform their own connecting. After
7621 application has created a connection it merely calls this
7622 function to start the key exchange between client and server.
7623 The library takes care of everything else after that.
7625 Updated also lib/silcclient/README to explain the usage of
7628 * Do not send to application information that connection has
7629 been established. Application gets notified it by connect
7632 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Applied cras's patch to add silc_schedule_one function. The
7635 function runs scheduler once and returns.
7637 * Fixed the scheduler after cras messed it up. The timeout
7638 handling works now as it's supposed to work.
7640 * Added into lib/silccore/ silcnotify.h to include notify
7641 message types support. Changed silc_server_send_notify*
7642 functions, in server.[ch], to support those new notify types.
7643 Added the support for the notify types into client library,
7644 as well. Added new notify client operation into ops.h in
7647 * Changed silc_server_packet_send_to_channel to send normal
7648 packets instead of just channel message packets. The function
7649 is now used to send the notify packets to channels. It is not
7650 used to send channel message packets anymore, as server never
7653 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7654 va_arg()s as it seems to require it nowadays. I guess, if SILC
7655 is compiled with older va_arg() the new code should work anyway.
7657 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7659 * Splitted core library. Core library (lib/silccore) includes
7660 now only SILC protocol specific core (and common) components.
7661 Created new utility library (lib/silcutil) that includes more
7662 generic purpose stuff. The stuff for util library was taken
7663 from the old core library. This was minor and easy split.
7665 * Created SILC Client Library (lib/silcclient) that includes
7666 implementation of the SILC client without user interface. This
7667 was major move from silc/ directory. The code has been changed
7668 so that it is transparent towards the user interface. The
7669 silc/ directory includes now the same user interface as before
7670 and it uses the new client library. Read lib/silcclient/README.
7671 Basicly, the client library performs everything else related
7672 to SILC except user interface handling. Also, configuration
7673 files are considered to be part of user interface and library
7674 does not handle them.
7676 This change also changed a lot of structures, function naming etc.
7677 Most important change was that SilcClientWindow object was
7678 renamed to SilcClientConnection in the client library. Created
7679 also new file lib/silcclient/ops.h. Also added new files
7680 silc/local_command.[ch] and silc/client_ops.[ch].
7682 All these changes were made to make it easier for user interface
7683 designers to create what ever user interface for the SILC client
7686 It is also expected that the server will be moved to lib
7687 directory as well and SILC Server Library will be created;
7688 sometimes in the future.
7690 * Removed Local commands from lib/silccore/silccommand.h as
7691 they are application specific and new client library does not
7692 handle any of those anymore.
7694 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7695 old client implementation in silc/.
7697 * Added support for callback functions in SILC_LOG_* macros.
7698 Application can now set its own callbacks that will be called
7699 instead of using the default functions that will always print
7700 the debug messages to stderr (or stdout). Also, debugging can
7701 now be disabled by setting silc_debug to FALSE and re-enabled by
7702 setting it to TRUE. Note, that logging will still work even
7703 if debugging is disabled.
7705 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7706 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7707 silc_log_reset_debug_callbacks.
7709 * To enable debugging in silc client one must give now -d
7710 option on command line.
7712 * Changed silc_schedule_init to automatically allocate task queues
7713 if they are not allocated before calling it.
7715 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7717 * Added GMP 3.1 into math library.
7719 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7721 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7722 a channel in SILC network. The packet is used by servers and
7723 routers to notify other routers that user has left a channel.
7724 This little feature was missing until now. Added the feature
7725 to protocol specification as well.
7727 Added functions: silc_server_send_remove_channel_user and
7728 silc_server_remove_channel_user into server.[ch].
7730 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7731 lib/silccore/silcpacket.h. However, they are not implemented
7734 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7736 * Fixed joining to a channel and sending channel messages
7737 between server and router. The channel message sending should
7738 now work inside a cell.
7740 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7742 * Fixed the private message sending between server and router.
7743 The private message sending should now work inside a cell.
7745 * Added silc_server_replace_id into server.[ch] to replace
7746 existing ID in the SILC network.
7748 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7749 and silc_idlist_replace_server_id into idlist.[ch] in server.
7751 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7753 * Fixed the server to server connections. Server can again now
7754 connect to router. Router to router connections probably does
7757 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7759 * Added dynamic protocol registering support. Now protocols can
7760 registered and unregistered on the fly. Patch by cras.
7762 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Added lib/contrib directory to hold routines that some platforms
7765 don't have but are needed by SILC.
7767 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7768 into lin/contrib to provide getopt() and getopt_long() for
7769 those who don't have it.
7771 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7773 * Added AWAY command to client. When away message is set and
7774 client receives a private message packet the client automatically
7775 replies to the sender with the away message.
7777 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7778 bug seemed to be the cause of recent problems when compiling
7781 * Added version detection support to SKE protocol specification
7782 and added the new changes to the SKE implementation as well.
7783 There were other minor changes in the SKE protocol as well.
7785 Many changes in lib/silcske/silcske.[ch] and in
7786 lib/silcske/payload.[ch].
7788 * Added ^U functionality, clear input line. Patch from cras.
7790 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Mainly small bugfixes on core library. Fixed some debugging
7793 logging and buffer overflow in silclog.c.
7795 * Updated config.sub and config.guess on the distribution tree.
7797 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Added command lagging support in server. Client may execute
7800 commands now only once in two seconds.
7802 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7804 * Optimized packet reception. MAC computation and checking is now
7805 also more optimized. A lot previously duplicated code is now
7806 used as generic by both client and server.
7808 * Fixed key pair generation in clientutil.c
7810 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Added into lib/silccore/silcbufutil.[ch] new function;
7813 silc_buffer_realloc.
7815 * Moved generic packet sending/encryption functions to
7816 lib/silccore/silcpacket.[ch] from client and server. Some
7817 rewriting of the functions.
7819 * Moved all generic packet reception/decryption functions to
7820 lib/silccore/silcpacket.[ch] from client and server. The
7821 packet processing is now much cleaner in both client and server.
7822 These were major changes in both client and server.
7824 * Created many common functions in server to do packet sending.
7825 Previously code were duplicated a lot, this has been removed
7828 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7830 * Rewrote major parts of the ID cache system. Don't know
7831 whether it is better now or not but at least the API is more
7834 * Major rewrite on ID cache stuff on client because of the ID
7835 cache API changes. Added idlist.c to client.
7837 * Also major rewrite on ID cache stuff on server as well.
7838 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7839 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7840 in hand, instead they are all put into the ID cache system now.
7841 All server_idlist_* routines uses ID cache now instead of
7842 traversing its own lists (those lists does not exist anymore).
7843 SilcIDList though still exists. Also, SilcXXXEntry's are
7846 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Finally made the SKE implementation compliant to the protocol
7849 specification. All mp integers are now binary encoded as
7850 opposed being HEX encoded.
7852 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7855 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7856 functions: silc_[encode/decode]_pem. Also added function
7857 silc_encode_pem_file to PEM encode with newlines ('\n') for
7860 * SILC public keys are now encoded either PEM or binary. Same
7861 option is for private keys as well. By default private keys
7862 are binary encoded and public keys PEM encoded. Silly HEX
7863 encoding were removed.
7865 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7866 function to create fingerprints.
7868 * Fixed a bug in SHA1; does not change the original data anymore.
7870 * Partly implemented INFO command on client and server side.
7871 Fixed CLEAR command. Changes to SERVER command; show current
7872 server(s) when giving command without arguments. Added
7873 VERSION command to client.
7875 * Added check to server that unregistered connections cannot
7876 execute commands (unless it is specificly allowed).
7878 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7880 * Fixed screen refresh.
7882 * Fixed channel joining bug from client. On some circumstances
7883 client tried to join to a channel it had already joined.
7885 * Added public key verification process into client's protocol.c.
7886 The client now verifies the public key from user and saves
7887 it into ~./silc/serverkeys/ directory.
7889 Added into: clientutil.[ch]: silc_client_verify_server_key.
7891 * Changed SKE protocol's silc_ske_initiator_finish function
7892 to accept callback function that verifies the received public
7893 key. Removed old silc_ske_verify_public_key function.
7895 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7898 silc_pkcs_private_key[_data]_set.
7900 * Made the password and public authentication more cleaner in
7901 server's protocol.c.
7903 * Removed historic and obsolete protocol `channel_auth' from
7904 both client and server.
7906 * Removed wrong way of sending command status messages from
7907 server to client in server's command.c. The old way violated
7908 protocol specification.
7910 Changes to silccore/silccommand.[ch]: removed
7911 silc_command_encode_status_payload -> not needed anymore,
7912 changed silc_command_encode_payload_va to accept extra
7913 argument on variable argument list. The argument type must
7914 now be provided to the function. Also, added new function:
7915 silc_command_encode_reply_payload_va which is same as
7916 normal command_encode_payload_va except command status type
7917 is provided as extra argument.
7919 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7921 * Added ~./silc directory handling. The directory includes the
7922 public and private keys for the client.
7924 Added silc_client_check_silc_dir, silc_client_create_identifier
7925 and silc_client_load_keys.
7927 * Implemented SILC protocol compliant public key. Added public
7928 and private key saving to and loading from files.
7930 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7931 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7932 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7933 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7934 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7936 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7937 silc_pkcs_load_[public/private]_key.
7939 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7941 * Added silc_server_get_route (route.[ch]) to get connection
7942 data for the fastest route for given ID.
7944 * Implemented INVITE command on client and server. The command
7945 were re-defined in the SILC Protocol Specification and the
7946 implementation now complies with the specification.
7948 * Implemented PING command on client and server.
7950 * Implemented NAMES command on client and server. The server side
7951 supports currently only normal server not router server yet.
7952 Some changes to NAMES definition in SILC protocol specification.
7954 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7956 * Implemented LEAVE command on client and server.
7958 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7959 again. This change was made to the protocol as well. Server
7960 should not violate the protocol specification anymore.
7962 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7964 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7965 was tested. SOCKS4 was not but should work anyway.
