1 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
3 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
4 must be handled by the application and should tell the application
5 that an error message was already printed, and it should print the
6 config coords (line, filename, ...). Affected files are
7 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
9 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
10 server config parsing code more readable.
12 Fixed a bug in the fetch_logging() config callback.
14 Affected files is silcd/serverconfig.c.
16 * Drop root privileges when started in foreground. Don't drop them
17 if debugging also. Affected file is silcd/silcd.c.
19 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
21 * Added STATS command to the protocol after all, to return
22 various statistical information about the network. It can
23 be used by clients to retrieve statistical information, and
24 servers may use it to to fetch cell and network wide
25 statistics from router. Updated the protocol specs and
26 implemented it to the server. Protocol TODO #16.
27 Affected files are lib/silccore/silccommand, silcd/command.[ch],
28 silcd/command_reply.[ch].
30 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
32 * The LIST command reply in client libary now adds new channel
33 entry if the returned channel doesn't exist yet in cache,
34 and returns the channel entry to the application in the
35 command_reply client operation. Affected file is
36 lib/silcclient/command_reply.c.
38 * Changed the channel message payload's MAC generation to
39 include the IV in the MAC as well. This way all relevant
40 parts of the channel message payload are authenticated also
41 with the channel message MAC (and not only by packet MAC).
42 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
43 Affected file is lib/silccore/silcchannel.c.
45 * Fixed the SKE to save the remote version, since the
46 silc_ske_parse_version mistakenly checked wrong version,
47 after it replaced the start payload. Affected files are
48 lib/silcske/silcske.[ch].
50 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
52 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
53 string utility functions. Added there also new functions
54 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
55 Affected files lib/silcutil/silcstrutil.[ch].
57 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
58 files are lib/silcutil/silcstrutil.[ch].
60 * Defined that the security property fields in SKE SHOULD be
61 UTF-8 encoded, defined that version string MUST be US-ASCII
62 encoded, defined that passphrases sent in connection
63 authentication protocol MUST be UTF-8 encoded. Implemented
64 these to the client and server. Defined also that other
65 passphrases sent in the protocol MUST be UTF-8 encoded.
66 Affected files are lib/silcske/silcske.c,
67 lib/silcclient/protocol.c, silcd/protocol.c,
68 silcd/serverconfig.c, and lib/silccore/silcauth.c.
70 * Changed the silc_client_close_connection interface to not
71 need the SilcSocketConnection which should not be visible
72 to application. Affected files are lib/silcclient/client.c
73 and lib/silcclient/silcclient.h.
75 * Rewrote the text for Private Message Key Payload in the
76 protocol specification. Protocol TODO #11.
78 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
80 * Upgraded the protocol version to 1.1, updated protocol specs
83 * Added the nickname as new argument to NICK_CHANGE notify and
84 added it to protocol specs and implemented it to client and
85 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
86 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
87 lib/silcclient/client_notify.c.
89 * Added the killer's client ID to the KILLED notify and added
90 it to protocol specs and implemented it to client and server.
91 Protocol TODO #13. Affected files are silcd/command.c,
92 silcd/packet_receive.c, packet_send.[ch],
93 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
94 The killer's client entry is now returned to application in
95 the `notify' client operation.
97 * Fixed the Max Argument fields that had too large value set
98 in the protocol specs. Protocol TODO #14.
100 * Added the LEAVE command reply to return the ID of parted
101 channel. Updated protocol specs and implemented it to the
102 client and server. Protocol TODO #15. Affected files are
103 silcd/command.c, lib/silcclient/command_reply.c. The channel
104 entry is now returned to application in the `command_reply'
107 * Rewrote the version SKE version checking in client libary
108 and in server to use the silc_parse_version_string. Affected
109 files are lib/silcclient/protocol.c, silcd/protocol.c.
111 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
112 commands that was missing it, and updated protocol specs and
113 the server implementation. Protocol TODO #10. The affected
114 file is silcd/command.c.
116 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
117 generic reply to a generic request (REQUEST flag), and
118 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
119 way. A draft-riikonen-silc-flags-payloads-00.txt is written
120 to define the payload for DATA flag. Added the flags to
121 the implementation. Protocol TODO #9. Affected file is
122 lib/silccore/silcchannel.h.
124 Changed the client library to return the message length
125 to application as well in the channel_message and private_message
126 client operations. Affected files are
127 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
128 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
129 and lib/silcclient/client_ops_example.c.
131 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
132 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
133 the channel. Updated protocol specs and impelemented this
134 to client and server. Protocol TODO #6. Affected files are
135 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
136 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
138 Added new options m and M to CMODE command in Irssi SILC
139 client to set these modes.
141 * Deprecated all administrative commands from SILC protocol
142 since they are highly implementation specific commands.
143 Updated protocol specs. Moved the old commands in
144 implementations to private range of command types. Affected
145 files are silcd/command.c, lib/silcclient/command.c and
146 lib/silcclient/command_reply.c. Protocol TODO #8.
148 * Fixed a bug in server where sending unknown command crashes
149 the server. Affected file silcd/command.c.
151 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
153 * Added SILC_PROTOCOLVERSION macro to check protocol version
154 of a socket connection. The affected file is
155 lib/silcutil/silcsockconn.h.
157 * Added better error logging in rekey protocol. Affected file
160 * Do not check public key types in SKE during rekey. Affected
161 file lib/silcske/payload.c.
163 * Fixed the rekey protocol with PFS, which was totally broken.
164 Affected file silcd/protocol.c.
166 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Some client implementations quit network by doing first LEAVE
169 and then immediately SIGNOFF (like Bombyx). We now do check
170 after a short time after LEAVE notify and check whether the
171 client is still valid after LEAVE, and if not we remove it from
172 cache. Affected file is lib/silcclient/client_notify.c.
174 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
176 * Merged version 1.1.4 of zlib. Even if it not currently in use,
177 it's good not to have security holes here.
179 * Fixed a negative refcount situtuation for the config context.
180 Affected file is silcd/serverconfig.c.
182 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
184 * ROBOdoc documented lib/silcutil/silcutil.h.
186 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Optimized even more the SilcPacketContext structure. Now
189 totally saved 16 bytes of memory per context after optimization.
190 Affected files are lib/silccore/silcpacket.[ch].
192 * Made strict checks for valid SILC IDs. Affected file is
193 lib/silccore/silcid.c.
195 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Changed the object argument for silc_cipher_register,
198 silc_hash_register, silc_hmac_register and silc_pkcs_register
199 to const. Affected files are lib/silccrypt/silccipher.[ch],
200 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
202 * Changed the silc_get_username and silc_get_real_name to
203 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
205 * Fixed the Irssi SILC Client to use the silc_get_username and
206 silc_get_real_name insted of glib routines since the glib
207 routines only corrupt stack. Fixes the Irssi SILC to work in
208 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
210 * Fixed the Irssi to not use g_get_home_dir since it crashes
211 or returns garbage on cygwin and corrupts stack. Added function
212 get_home_dir to Irssi routines. Affected files are
213 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
215 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
217 * Made some structure optimizations. SFTP memory FS MemFSEntry
218 entry structure. Optimized SilcTask structure. Optimized
219 SilcPacketContext structure.
221 Affected files lib/silcsftp/sftp_fs_memory.c,
222 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
224 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
226 * And yet again reverted back the config thing since Johnny
227 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
230 * Fixed memory leaks from config object. Affected files are
231 silcd/serverconfig.[ch].
233 * Added support for adding new connections to the server in rehash.
234 After rehash they take effect.
236 Added support for changing the maximum allowed connections in
237 rehash. The number can grow but going smaller is not supported.
239 Added function silc_server_num_sockets_by_remote to the
240 silcd/server_util.[ch].
242 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
244 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
246 * Added preliminary checking during config parsing for a valid
247 public/private key and removed further checks in the code.
248 Affected files are silcd/serverconfig.[ch], server.c.
250 * Moved functions silc_server_drop() and silc_server_daemonise()
251 from server.c to silcd.c since they are stricly related to
252 the application activity.
254 * Reverted a small part of the automatic ref/unref since
255 it caused a double unref in some situations. Affected
256 files are silcd/silcd.[ch], server.c, serverconfig.c.
258 * Added some .cvsignore files in the lib directory.
260 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Fixed silc_net_gethostbyaddr to correctly resolve by
263 address. Affected file lib/silcutil/silcnet.c.
265 * Fixed the notify relaying to client. The HMAC to be used
266 with relayed packets ws wrong and caused decryption failure
267 at the client end. Affected file is silcd/packet_receive.c.
269 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
271 * Created new branch silc_protocol_1_0_branch.
273 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
275 * Changed the silc_server_config_* routines to be SilcServer
276 independent. They are now officially application specific code
277 and not part of generic server implementation. Affected files
278 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
280 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
282 * Added automatic referencing of config context in the
283 silc_server_config_alloc, and automatic unreferencing in the
284 silc_server_config_destroy. Affected files are
285 silcd/serverconfig.[ch], silcd/silcd.c.
287 * Fixed the silc_log_quick handling in the logging routines.
288 It didn't log quickly when it was TRUE. Affected file is
289 lib/silcutil/silclog.c. Also the flush delay was set even
290 if it was 0 in config file. Affected file is
291 silcd/serverconfig.c.
293 * Added support for changing key pair of the server in rehash.
294 Affected file silcd/server.c.
296 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Fixed the TOPIC_SET notify to not cras. It changed the topic
299 too early, before getting the channel entry. Affected file
300 is silcd/packet_receive.c.
302 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
304 * Added functions silc_server_config_[ref/unref], these are used
305 to prevent that the config object is destroyed.
307 No longer directly affect global variables silc_log_quick and
308 silc_log_delay, they are first cached inside the config object
309 and then applied with silc_server_config_setlogfiles().
311 silc_server_config_set_defaults() is now internal to
312 serverconfig.c, there are no reasons to show this internal stuff
315 Affected files are silcd/serverconfig.[ch].
317 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
318 fprintf's to stderr, since some code may be executed again after
319 the server went into the background. Affected files are
322 * Added rehash support. Added function silc_server_rehash() that
323 will perform all the basic tasks of the rehashing procedure.
325 * Added command line option `-x, --hexdump'. This will enable the
326 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
327 The option `--hexdump' implies `--debug'.
329 * Fixed a bad bug in the logging APIs (silcutil library) where
330 the application would crash after calling silc_log_reset_all().
332 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
334 * Fixed the KICKED notify handling in client library to
335 correctly remove the channel and all entries from the
336 channel when I was kicked. This bug crashed the client.
338 Fixed yet another but in KICKED notify handling to remove
339 the kicked client correctly from the channel.
341 Affected file is lib/silcclient/client_notify.c.
343 * Fixed a minor bug in looking up correct client entry
344 in KICKED notify in server. Affected file is
345 silcd/packet_receive.c.
347 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
348 sources correctly to distribution. Fixes --with-gmp option.
350 * Removed the manual rehashing from ID Cache, and changed it
351 to use the SILC Hash Table's auto rehash feature. Affected
352 file is lib/silccore/silcidcache.c.
354 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
356 * Fixed a bug in the silc_client_nickname_format function that
357 handles the multiple same nickname formatting. Two clients
358 with same nickname caused problems after the first one left
359 and rejoined. It didn't format the nickname correctly.
360 Affected file is lib/silcclient/idlist.c.
362 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
364 * Don't change the topic if olod topic is same as new one.
365 Affected file is silcd/packet_receive.c.
367 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
369 * Added cross-reference support to the SILC Documentation
370 generator. All types across all HTML files are now cross-
371 referenced. Affected files util/robodoc/generator.c and
372 scripts/silcdoc/silcdoc.
374 * Added file lib/silcutil/silctypes.h to include all the
375 arithmetic type definitions and some macros. Removed
376 includes/bitmove.h and moved macros to silctypes.h.
378 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
380 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
382 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Added `type' argument to silc_id_payload_parse_id function which
385 now returns the type of the ID to the sent pointer. Affected
386 file is lib/silccore/silcid.[ch].
388 * Added check for CMODE_CHANGE notify type that mode change is
389 allowed by the sender. Affected file silcd/packet_receive.c.
391 * Added check for CUMODE_CHANGE notify type that mode change is
392 allowed by the sender. Affected file silcd/packet_receive.c.
393 Added the ID type as CUMODE_CHANGE notify type as argument
394 to the `notify' client operation. Affected files are
395 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
397 * Added function silc_client_add_server to the client library.
398 Added support for resolving also channel and server info when
399 received unknown entity in notify packet. Affected files are
400 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
402 * Added function silc_command_get_status to return the command
403 status from the command reply's argument payload. Affected files
404 are lib/silccore/silccommand.[ch].
406 * Added check for KICKED notify type that the kicking is
407 allowed by the client. Affected file silcd/packet_receive.c.
409 * Created function silc_get_input which can be used to get input
410 (echo on or off) from user on command line. Affected files are
411 lib/silcutil/silcutil.[ch].
413 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Optimized silc_server_packet_relay_to_channel function.
416 Added new function silc_channel_message_payload_encrypt which
417 can be called directly if channel message payload needs to
418 be encrypted and is already encoded (no need to call _encode
419 function). Packet relaying is now done by router without any
420 extra memory allocations. Affected files are
421 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
424 * Fixed the INVITE notify handling. It took wrong arguments
425 as invite list and invite delete. Affected file is
426 silcd/packet_receive.c.
428 * Added check for TOPIC_SET notify type that the topic change is
429 allowed by the client. Affected file silcd/packet_receive.c.
431 * Added check for INVITE notify type that inviting is allowed by
432 the client. Affected file silcd/packet_receive.c.

435 SilcChannelClientEntry as well. Moved the function
436 silc_server_check_cmode_rights to server_util.[ch].
437 Affected files are silcd/server_util.[ch], silcd/command.c.
439 * Added function silc_server_check_umode_rights to check whether
440 changing client's user mode is allowed. Added check for
441 UMODE_CHANGE notify type that the umode change is allowed
442 by the client. Affected files are silcd/server_util.[ch],
443 silcd/packet_receive.c and silcd/command.c.
445 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
447 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
448 ID length. It ignored that ID can be IPv6 based as well.
449 Affected file lib/silccore/silcpacket.h.
451 * Fixed the silc_id_id2str and silc_id_str2id to take the
452 IPv6 address offset's into consideration. Affecte file is
453 lib/silccore/silcid.c.
455 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
457 * Fixed the internal Unix scheduler functions to check for
458 NULL context they may receive. The affected file is
459 lib/silcutil/unix/silcunixschedule.c.
461 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
463 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
464 can specify different directory with --home command line
465 parameter. Affected files irssi/src/silc/core/client_ops.c,
468 * SILC-specific commands aren't now executed if the active server
469 isn't of SILC-type, so there won't be problems with having
470 IRC and SILC protocol support in same client. Affected files
471 irssi/src/silc/core/silc-channels.c, silc-servers.c,
474 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
476 * Improved the signal support in SILC Schedule. Added new
477 function silc_schedule_signal_call which is used by application
478 to mark a signal to be called. It is now safe to perform
479 any kind of tasks in signal callbacks since it is guaranteed
480 that the application specified signal callback is called
481 after the signal is over. Affected files are
482 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
484 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
486 * Added `name' field to SilcChannelPrivateKey to represent
487 application given name for the key. Moved also the context from
488 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
489 Added the `name' argument also to the function
490 silc_client_add_channel_private_key.
492 Added function silc_client_current_channel_private_key to set the
493 current channel private key in use.
495 Added "change" command to KEY command which can be used to change
496 the current channel private key. Bound the command also to
499 Also affected files lib/silcclient/client_channel.c,
500 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
502 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
504 * Added silc_rng_get_byte_fast function in to the
505 lib/silccrypt/silcrng.[ch].
507 * Changed the interface of silc_packet_assemble and the
508 silc_packet_send_prepare. If silc_packet_assmble is now
509 called the application does not call silc_packet_send_prepare
510 because the library will call it automatically. These
511 interfaces now also return a reference to the outgoing buffer
512 which includes the assembled packet, which the application can
513 use to encrypt the packet.
515 Affected files are lib/silccore/silcpacket.[ch],
516 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
517 silcd/packet_send.c, server_backup.c and packet_receive.c.
519 * Fixed a packet sending bug on very high load, where outgoing
520 packet queue wasn't handled correctly and packets got corrupted.
521 Affected files are lib/silcutil/*/silc*sockconn.c,
522 lib/silcclient/client.c and silcd/server.c.
524 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Added macro SILC_PACKET_DATALEN which can be used during
527 packet assembling to check whether the data to be added to
528 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
529 len is truncated until it fits it.
531 Added checks for maximum length of channel message payload and
532 private message payload also.
534 Added checks for maximum packet length in server and in
537 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
538 lib/silcclient/client.c, lib/silccore/silcchannel.c and
539 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
540 lib/silcclient/client_prvmsg.c.
542 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
544 * Added silc_server_packet_queue_purge call to the
545 silc_server_disconnect_remote to assure that all data in the
546 queue before disconnecting is sent to the network. Affected
549 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Added the deleting of server's own ID cache entry to the
552 silc_server_free function. Free also everything else that
553 has been allocated in silc_server_init. The affected file
556 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
558 * Added functions silc_parse_version_string, silc_version_to_num,
559 and silc_ske_parse_version to parse SILC protocol style version
560 strings. Affected files lib/silcutil/silcutil.[ch] and
561 lib/silcske/silcske.[ch].
563 * Added new configuration params: version_protocol, version_software
564 and version_software_vendor to specify what version the remote
565 host must at least be to be able to connect to server. The vendor
566 string can be regex matched too. Added new function
567 silc_server_connection_allowed to check maximum number of allowed
568 connections, and allowed versions for incoming connections.
569 Affected files are silcd/server.c, server_util.[ch] and
572 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
574 * Added preliminary support for signals in scheduler. The
575 signals we care about are now blocked always when the scheduler
576 is locked. This way we can synchronise the use of signal with
577 scheduler. It is guaranteed that when signal occurs the scheduler
578 is not locked, and thus new tasks can be safely added to the
581 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
582 to silc_schedule_internal_init and silc_schedule_internal_uninit.
583 Added new platform specific routines
584 silc_schedule_internal_signals_[un]block and
585 silc_schedule_internal_signal_[un]register.
587 Added new functions to SILC Schedule API:
588 silc_schedule_signal_[un]register. Each signal that application
589 is going to use should be registered to the scheduler.
591 Affected files are lib/silcutil/silcschedule.[ch],
592 lib/silcutil/*/silc*schedule.c.
594 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
596 * Check for unauthenticated client and server in the
597 silc_server_new_client and silc_server_new_server functions.
598 Affected file silcd/packet_receive.c.
600 * Added function silc_string_is_ascii to check whether given
601 string is 7-bit ASCII string. Affected files are
602 lib/silcutil/silcutil.[ch].
604 * Added function silc_id_is_valid_server_id into the
605 silcd/serverid.c and added checking for valid Server ID's in
606 silc_server_new_server. The Server ID must always be based
607 on the server's public IP address.
609 * Added logging of DISCONNECT packet message in the server.
610 Affected file silcd/server.c.
612 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Changed all library interfaces that use Global RNG to also
615 accept SilcRng as argument. Affected files are
616 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
617 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
618 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
619 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
622 * Added function silc_pkcs_generate_key to the
623 lib/silccrypt/silcpkcs.[ch] for applications so that they
624 don't need to do pkcs->pkcs->init calls anymore.
626 * Remove SilcSocketConnection from the SFTP API since it really
627 wasn't needed there. The application has the information
628 saved in its contexts anyway and the SFTP layer doesn't need
629 know about it. Affected files lib/silcsft/silcsftp.h and
630 lib/silcsftp/sftp_[server/client].c.
632 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
633 The SilcSimContext is not SilcSim.
635 * Fixed possible buffer overflows in silc_id_render in the
636 lib/silcutil/silcutil.c.
638 * On EPOC the global crypto module lists are not used at all
639 in the crypto library. Added support for using the constant
640 algorithm list on EPOC. Affected files are
641 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
644 * Fixed the handling of third parameter of KICKED notify, since
645 it was mistakenly updated to SILC Protocol 1.0 even though it
646 is to be included in 1.1. Since it is not in 1.0 it is not
647 mandatory, and this fix now handles it only if it is provided,
648 and it is not error if it is not provided. Affected file
649 lib/silcclient/client_notify.c.
651 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
653 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
654 client. Affected file irssi/src/silc/core/client_ops.c.
656 * Merged with Irssi 0.8.4 from irssi.org CVS.
658 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
660 * Check for valid socket connection in client entries before
661 sending any messages. Fixes a crash, but doesn't fix some
662 other underlaying bug that is lurking there. Affected
663 file silcd/packet_send.c.
665 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
667 * $usermode, $cumode and $cumode_space expandos shouldn't do
668 anything with non-SILC server records. Affected file
669 irssi/src/silc/core/silc-expandos.c
671 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
673 * Fixed the silc_net_check_[host/local]_by_sock to support
674 IPv6 bound sockets as well. Now they can return IPv6 addresses
675 as well. Affected file lib/silcutil/silcnet.c.
677 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
678 Affected lib/silcutil/unix/silcunixnet.c.
680 * Fixed ID rendering (at least on some platforms, not NetBSD)
681 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
683 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
685 * Added silc_hash_public_key and silc_hash_public_key_compare
686 functions to be used with SilcHashTable. They can be used to
687 hash public keys and compare public keys in hash table. Affected
688 file lib/silcutil/silcutil.[ch].
690 * Added support for specifying multiple public keys for Client
691 connection section in server configuration file. This makes it
692 possible to accept multiple public keys from same host, or to
693 make a section that accepts any incoming host, and have the
694 accepted public keys listed in the section.
696 Added functions silc_sever_[find/get]_public_key, added the
697 support for this actually to all connection sections but only
698 the Client section is currently allowed to specify multiple
701 Affected files are silcd/server.c, server_internal.h,
702 command.c, protocol.c, server_util.[ch], packet_receive.c.
704 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

708 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
710 * If silc_debug is TRUE, also output standard logging messages
711 to stderr with the debug output.
713 Made silc_log_reset_all() flushing all channels before returning.
714 Also fixed some documentation typos.
716 Affected files are lib/silcutil/silclog.[ch].
718 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
720 * Fixed the server to check correctly the amount of connections
721 from single host, by checking also the type of the connection.
722 Fixed also the comparison of number of connections and number
723 of allowed connections. Affected files are silcd/server.c,
726 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Fixed the USERS command reply to save the user's mode on the
729 channel as well. Fixed JOIN command reply to check whether a
730 client is on channel already and not join it twice. Affected
731 file lib/silcclient/command_reply.c.
733 * Added new file silc-expandos.c into irssi/silc/core/ to return
734 various stuff for various signal for the statusbar etc. updating.
735 Now Irssi SILC client prints channel user modes etc. on the
738 * The user mode (like server/router operator changes) is now shown
739 on the Irssi SILC client's statusbar. The affected files are
740 irssi/src/silc/core/client_ops.c, silc-expandos.c.
742 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
744 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
745 to SILC_SCHEDULE_[UN]LOCK macros.
747 * Added more error printing to logs in server code. Affected
748 files silcd/server.c and silcd/protocol.c.
750 * Fixed -S option parsing in Irssi SILC Client. Affected file
751 irssi/src/silc/core/silc-core.c.
753 * Added silc_buffer_alloc_size function. Affected file is
754 lib/silcutil/silcbuffer.h.
756 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
758 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
759 constants. Affected files in
760 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and

768 * Fixed the buffer formatting and unformatting routines to
769 check the size of 64 bits types with sizeof(). Affected
770 file is lib/silcutil/silcbuffmt.c.
772 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Removed 0.6.x backwards support.
776 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
778 * Changed all integer type names:
779 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
780 to avoid collisions with other libraries using same type names
783 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
785 * Added `prefer_ipv6' argument to the functions
786 silc_net_gethostbyname[_async]. If it is TRUE it will return
787 IPv6 address over IPv4. If FALSE IPv4 address is returned
788 even if IPv6 address was found. Affected files
789 lib/silcutil/silcnet.[ch].
791 * Added support silc_net_create_connection[_async] to fallback
792 to IPv4 address if IPv6 address could not be used (like if

805 application does not need to define them. Affected file
806 includes/silcincludes.h.
808 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
809 old name went against naming convention. Applications now
810 include "silcclient.h" instead of "clientlibincludes.h".
811 Removed includes/clientlibincludes.h, it is redundant now.
813 * Renamed includes/version.h to silcversion.h.
815 * Added really preliminary support for OS/2 into the util
816 library. Only thread & mutex API is implemented, others
817 are still to be implemented. Created the lib/silcutil/os2/
818 directory. Created also file includes/silcos2.h.
820 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
822 * Added preliminary BeOS support into the util library.
823 Created lib/silcutil/beos/, and implemented all the needed

829 * Added proper initializations to silc's irssi code, so it's
830 now possible to load it as module. Affected files
831 irssi/src/silc/core/silc-core.c,
832 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

849 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Added `user_count' to the SilcChannelEntry which now tells the
852 number of users on the channel. The user count is now saved
853 in normal server of global channels as well. Affected files
854 silcd/server.c, idlist.h, packet_receive.c and command.c.
856 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
857 include file utility functions.
859 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
860 instead of calling directly OS routines.
862 * Fixed NICK change printing in Irssi SILC Client. Fixed
863 KICKED notify printing in Irssi SILC Client. Affected file
864 irssi/src/silc/core/client_ops.c.
866 * Fixed a NICK change bug in client library, to not recreate the
867 client_entry->channels hash table everytime nick is changed.
868 Affected file lib/silcclient/client.c.
870 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
872 * ROBOdoc documented the lib/silcske/silcske.h, and improved
873 the SKE interface a bit.
875 * Fixed padding problem in PKCS#1. The padding was not actually
876 random since the random number generator was used incorrectly.
877 This security bug affects only when encrypting with PKCS#1, and
878 it is not currently used at all in SILC. SILC only use signing
879 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
881 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

939 is now done in silc_core_init() which also fixes autoconnecting
942 Affected files irssi/src/silc/core/silc-core.c,
943 irssi/src/fe-text/silc.c.
945 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
947 * Added new configuration options and blocks:
948 keepalive_secs, reconnect_count, reconnect_interval,
949 reconnect_interval_max, reconnect_keep_trying and
950 require_reverser_lookup. Added ConnectionParam block, and
951 implemented the connection parameters when connecting as
952 initiator and when accepting connections as responder.
954 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
955 whether given configuration value has been given already.
957 Affected files silcd/serverconfig.[c], server.[c].
959 * Splitted the doc/example_silcd.conf.in. Separated the crypto
960 algorithm parts and created new file silcalgs.conf, that
961 is now included from the example_silcd.conf.in.
963 * Optimized the silc_server_connect_to_router_second to take
964 the connection configuration object from the SilcServerConnection
965 object instead of finding it during the connecting phase.
966 Added the configuration object to SilcServerConnection struct.
967 Affected files silcd/server_internal.h, server.c.
969 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Add the client on channel after it was resolved at the
972 channel message receiving, and it was not already on the
973 channel. Affected file lib/silcclient/client_channel.c.
975 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
977 * Fixed the public key authentication to allocate always the
978 destination signature buffer instead of using static buffer.
979 Affected file silcd/protocol.c.
981 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
983 * Unified the serverconfig.[ch]'s helper function interface.
984 Affected file silcd/serverconfig.[ch].
986 * Removed doc/example_silc.conf.in since it is redundant.
987 The make install will now install irssi/silc.conf file.
989 * Added new Passphrase and Publickey authentication methods to
990 config file, allowing both public key and passphrase based
991 authentication to be set at the same time.
993 Added `prefer_passphrase_auth' setting in config file which
994 can be used to set to prefer passwd auth if both passwd and
995 public key is set. If not set, public key is preferred.
996 This has effect only when being initiator (responder will try
999 Added support for authentication with passphrase and public key
1000 at the same time. The passphrase is tried first always since
1001 it is faster to check.
1003 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1005 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1051 * Fixed the file transfer's key agreement payload to include
1052 zero port also if the hostname is NULL because it could not
1055 Call file transfer monitor callback now also if error occurs
1056 during key agreement protocol.
1058 Changed the silc_client_file_send interface to return the
1059 SilcClientFileError instead of session id. The session ID
1060 is returned into pointer provided as argument.

1069 file lib/silcclient/silcapi.h.
1071 * Fixed the event_mode CMODE handler to not crash when mode
1072 is changed and +k mode is set in the channel. Affected file
1073 irssi/src/silc/core/silc-channels.c.
1075 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1076 SILC_LOG_WARNING to give out Warning and not Error. Affected
1077 file lib/silcutil/silclog.c.
1079 * Fixed the channel message payload decryption in the function
1080 silc_channel_message_payload_decrypt to not modify the original
1081 buffer before it is verified that the message decrypted
1082 correctly. Otherwise, next time it is called with correct
1083 channel key it won't encrypt since the payload is corrupted.
1084 Affected file lib/silccore/silcchannel.c.
1086 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1088 * Do not constantly resize the window. A fix patch by cras.
1089 Affected file irssi/src/fe-text/screen.c.
1091 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1093 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1094 Affected file lib/silcutil/silcnet.c.
1096 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Fixed a bug in hash table internal routine for traversing
1099 the table with foreach callback. The current entry may
1100 become invalid in the callback but it was referenced after
1101 the callback returned.
1103 Do not allow auto rehashing of hash table during the
1104 silc_hash_table_foreach operation, for same reasons as it is
1105 not allowed for SilcHashTableList. Affected files are
1106 lib/silcutil/silchashtable.[ch].
1108 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1110 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1111 Win32 DLL. extern's in header files are now declared with
1114 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1116 * Fixed private message handling. It used some old code that
1117 caused the client to crash. Affecte file is
1118 lib/silcclient/client_prvmsg.c.
1120 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Added function silc_client_add_channel,
1123 silc_client_replace_channel_id, and removed functions
1124 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1125 from client library.
1127 * Added cross reference of the joined channels to the
1128 SilcClientEntry, and changed the SilcChannelEntry's
1129 users list to SilcHashTable. The affected files are
1130 lib/silcclient/idlist.[ch].
1132 * Fixed a bug in hash table tarversing. While the hash table
1133 is traversed with SilcHashTableList the table must not be
1134 rehashed. It is now guaranteed that auto rehashable tables
1135 are not rehashed while tarversing the list. Also defined that
1136 silc_hash_table_rehash must not be called while tarversing
1137 the table. Added function silc_hash_table_list_reset that must
1138 be called after the tarversing is over. The affected files are
1139 lib/silcutil/silchashtable.[ch].
1141 * Changed all hash table traversing to call the new
1142 silc_hash_table_list_reset in server and in client library.
1144 * Added function silc_client_on_channel to return the
1145 SilcChannelUser entry if the specified client entry is joined
1146 on the specified channel. This is exported to application as
1147 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1149 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1151 * Fixed founder regaining problem with JOIN command on normal
1152 server. The notify for mode change must be sent always and
1153 not only if !cmd->pending. Affected file silcd/command.c.
1155 * Fixed the WHOWAS command's reply sending to support the
1156 lists correctly. Affected file silcd/command.c.
1158 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1160 * When sending JOIN command to router for processing the
1161 sender's old command identifier was not saved back to the
1162 sender's command context, fixed now. The affected file is
1165 * Create the key in JOIN command of the router did not return
1166 the channel key, added check for this. Affected file is
1169 * Fixed a channel ID update bug in JOIN command reply. Do
1170 not directly upgrade the ID but call the function
1171 silc_idlist_replace_channel_id if the ID was changed.
1172 Affected file silcd/command_reply.c.
1174 * Fixed memory leaks from command calling if it would fail.
1175 Affected file silcd/command.c.
1177 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1179 * Applied patches from cras:
1181 Memory leak fixes around libaries, irssi window resize fix,
1182 new silclist.h and silcdlist.h, all extern inline changed to
1185 * Removed dotconf from lib/dotconf, not needed anymore.
1187 * Removed TRQ from lib/trq, not needed anymore.
1189 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1190 with server connections. Later this will be configurable
1191 in config file after new config file is done. Affected file
1194 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1196 * Fixed a crash in server related to channel announcements.
1197 Affected file silcd/server.c.
1199 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Fixed memory leaks in silc_server_create_new_channel*
1202 functions. Affected file silcd/server.c.
1204 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1205 which ID was changed. This way the router will send the
1206 user list for the channel again, and server won't be in
1207 desync in some rare circumstances. Affected file is
1208 silcd/packet_receive.c.
1210 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1212 * Check for NULL socket pointer in the function
1213 silc_server_packet_send_to_channel_real. Affected file
1214 silcd/packet_send.c.
1216 * Fixed the BAN notify handling to correctly remove ban
1217 list. Affected file silcd/packet_receive.c.
1219 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1221 * Fixed some header addition to Toolkit distribution in
1222 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1224 * Added lib/silcclient/client_ops_example.h as an template
1225 file for application programmers to quickly start using
1226 the SilcClientOperation functions in their application.
1227 Updated the lib/silcclient/README as well to tell about this
1228 nice file made available.
1230 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1232 * Call silc_server_remove_from_channels when removing client
1233 entry when NO_SUCH_CLIENT_ID was received. Affected file
1234 is silcd/command_reply.c.
1236 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1238 * Added server & router operator statistics updating. Affected
1239 file silcd/packet_receive.c and silcd/command.c.
1241 * Fixed the SERVER_SIGNOFF notify handling on normal server
1242 not to save the history information for clients. Same was
1243 fixed earlier in remove_clients_by_server function, but not
1244 here. Affected file silcd/packet_receive.c.
1246 * Raised the default connection-retry count from 4 to 7 in
1247 server. Affected file silcd/server.h.
1249 * Cancel any possible reconnect timeouts when we start the
1250 key exchange. Affected file silcd/server.c.
1252 * Do not reconnect on connection failure when SCONNECT was
1253 given. Affected files silcd/server.[ch].
1255 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1257 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1259 * Fixed the NICK command to always give the unformatted
1260 nickname to the one giving the NICK command. If unformatted
1261 nickname is cached already it will be formatted and the
1262 local entry will always get the unformatted nickname.
1263 Affected file lib/silcclient/idlist.c.
1265 * Fixed some double frees from client library commands.
1266 Affected file is lib/silcclient/command.c.
1268 * Fixed CUMODE command in server to assure that no one can
1269 change founder's mode than the founder itself, there was a
1270 little bug. Affected file silcd/command.c.
1272 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Removed the SilcClientCommandDestructor from the client
1275 libary, it is not needed anymore. Affected files are
1276 lib/silcclient/silcapi.h, command[_reply].[ch],
1277 client_notify, idlist.c.
1279 * Fixed GETKEY command to first resolve client, and then
1280 resolve the server only if the client was not found, instead
1281 of resolving both at the same time. Affected file is
1282 lib/silcclient/command.c.
1284 * Added silc_client_start_key_exchange_cb and lookup the
1285 remote hostname and IP address before starting the key
1286 exchange with server. The affected file is
1287 lib/silcclient/client.c.
1289 * The server's public key is now saved using the IP address
1290 of the server and not the servername for the filename.
1291 The hostname public key filename is checked as an fall back
1292 method if the IP address based filename is not found.
1294 Fixed the GETKEY command to save the fetched server key
1295 in correct filename.
1297 Print the remote server's hostname now when new key is
1298 received during connection process. Affected file is
1299 irssi/src/silc/core/client_ops.c.
1301 * Return always our own public key to the client if it asks
1302 for it with GETKEY command. Affected file silcd/command.c.
1304 * Removed the use_auto_addr variable from default config
1305 file since it was in wrong section. Affected file is
1308 * Fixed TOPIC_CHANGE notification to not route it when it
1309 was sent using silc_server_send_notify_to_channel function.
1310 Affected file silcd/command.c.
1312 * Fixed silc_server_send_notify_kicked to send the kicker's
1313 Client ID also, it was missing. Affected files are
1314 silcd/command.c, silcd/packet_send.[ch].
1316 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1318 * Do not save client history information in SERVER_SIGNOFF.
1319 Fixes the bug in normal server that it does not detect
1320 the client becoming valid after the server becomes back
1321 online. Affected file silcd/server_util.c.
1323 * Added `sock_error' field into the SilcSocketConnection
1324 context. When error occurs during socket operation (read
1325 or write) the error is saved. Added also new function
1326 silc_socket_get_error to return human readable socket error
1327 message. Affected files are lib/silcutil/silcsockconn.[ch],
1328 lib/silcutil/unix/silcunixsockconn.c, and
1329 lib/silcutil/win32/silcwin32sockconn.c.
1331 * The server now prints the socket error message in the
1332 signoff for client. Affected file silcd/server.c.
1334 * Fixed the `created' channel information sending from router
1335 to server in JOIN command. Checks now whether the channel
1336 really was created or not and set it according that.
1338 Fixed the JOIN command to use the client entry's current
1339 ID during the joining procedure instead of the one it sent
1340 in the command (it is checked though), since it can change
1341 between the packet processing and command processing, and
1342 would just case unnecessary pain in the client end. Affected
1343 file silcd/command.c.
1345 * Fixed a channel key payload sending to use correct channel
1346 ID when the server was forced to change the channel's ID by
1347 router. Router sent the key payload with the old Channel ID.
1348 Affected file silcd/packet_receive.c.
1350 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1352 * Call silc_server_save_channel_key only if the key payload
1353 was provided in the JOIN command's command reply. Affected
1354 file silcd/command_reply.c.
1356 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed silc_mp_sizeinbase to return the value correctly with
1359 MPI. Affected file lib/silcmath/mp_mpi.c.
1361 * Fixed the stop_server signal to correctly stop the scheduler
1362 and gracefully stop the server when SIGTERM or SIGINT signals
1363 are received. Affected file silcd/silcd.c.
1365 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1367 * Simple handling of TERM and HUP signals. Also added some log
1368 flushing call around. Affected file is
1371 * Fixed small bugs in silclog.c. Now buffering output will take
1372 effect after 10 seconds since startup: This will ensure that
1373 no important startup messages are lost. Also output redirection
1374 will preserve original format ([Date] [Type] message).
1375 Affected file is lib/silcutil/silclog.c.
1377 * Added two options to the config file, in the logging section:
1378 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1379 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1381 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1383 * Do not print the warning about log files not being initialized
1384 more than once to avoid excess logging. Affected file is
1385 lib/silcutil/silclog.c.
1387 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1388 the SIM copying in make install in Makefile.am.pre.
1390 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1392 * Rewritten silclog APIs. Globally interesting changes follows:
1393 silc_log_set_files() changed to silc_log_set_file().
1394 silc_log_set_callbacks() changed to silc_log_set_callback().
1395 ROBOdoc documented silclog header file.
1396 SilcLogCb now returns bool to wether inihibit the default
1397 handler or not (to keep the old behaviour return always TRUE).
1398 The new APIs should also fix the problem of the
1399 silcd_error.log file that was written in the current directory.
1402 Log files streams will remain opened after silc_log_set_file()
1403 call, means less CPU usage notably on high traffic servers.
1404 File streams are now full buffered, and flushed to the disk
1405 every 5 minutes, lesses HD activity and CPU usage.
1406 Messages can be redirected, allowing admins to configure
1407 one single logfile for all server messages.
1408 the silc_log_quick global variable to activate fast-logging.
1409 Affected files lib/silcutil/silclog.[ch]
1411 * Changed some code to conform new silclog APIs. Affected
1412 files are doc/example_silcd.conf.in, silcd/server.c
1413 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1416 * Fixed a memory leak that could occur in some situations.
1417 Affected file silcd/serverconfig.c.
1419 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1421 * Added the silc_client_del_client to remove the client from
1422 all channels as well. Affected file lib/silcclient/idlist.c.
1424 * Fixed the client library to correctly remove the client
1425 from all channels when the client entry is being destroyed.
1426 Affected file lib/silcclient/client_notify.c, command.c.
1428 * Added auto-nicking support to the client library. If the
1429 applicatio now sets client->nickname it will be sent to the
1430 server after connecting by the library. This way for example
1431 SILCNICK (or IRCNICK) environment variables will have effect
1432 and always change the nickname automatically to whatever
1433 it is wanted. Affected file lib/silcclient/client.[ch].
1435 * Renamed silc_server_command_bad_chars to the
1436 silc_server_name_bad_chars and moved it to the
1437 silcd/server_util.[ch]. Added also new function
1438 silc_server_name_modify_bad to return nickname that
1439 includes bad characters as new nickname without those
1440 bad characters. This check and modify is now used in
1441 silc_server_new_client when the username is initially set
1442 as nickname, so it must be checked to be valid nickname.
1443 Affected file silcd/packet_receive.c.
1445 * The nickname length is now taken from the packet for real
1446 and not trusted to strlen() since it clearly can return
1447 wrong length for nickname including bad characters. This
1448 also applies to channel names. Affected file silcd/command.c.
1450 * Removed the lib/silcsilm/modules directory. Modules are now
1451 compiled into the lib/silcsim. Fixed the copying of the
1452 modules to follow symbolic links in Makefile.am.pre.
1454 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1456 * Fixed silc_string_regexify list creation. Fixes bugs with
1457 BAN and INVITE commands in server. The affected file is
1458 lib/silcutil/unix/silcunixutil.c.
1460 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Removed the command destructor entirely from the server's
1463 command and command reply routines. It is not needed, and
1464 its usage was buggy and caused crashes. Affected files are
1465 silcd/command[_reply].[ch].
1467 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Cancel protocol and NULL sock->protocol if timeout
1470 occurred during protocol. Affected file silcd/server.c.
1472 * Cancel protocol timeouts always before calling the final
1473 callback, to assure that after final callback is called
1474 no other state will be called for the protocol anymore.
1475 Affected file silcd/protocol.c.
1477 * Print error log if incoming connection configuration could
1478 not be found. Affected file silcd/server.c.
1480 * Fixed JOIN command to correctly save the founder mode
1481 to the client on normal SILC server, when the channel
1482 was created by the router. Affected file silcd/command.c.
1484 * Fixed LIST command (hopefully) to send correct reply
1485 packets. Affected file silcd/command.c.
1487 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * The silc_packet_receive_process now returns FALSE if the
1490 read data was invalid packet, and TRUE if it was ok.
1492 The server now checks that if unauthenticated connection
1493 sends data and its processing fails the server will close
1494 the connection since it could be a malicious flooder.
1496 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1498 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Make sure the warning about error opening a log file is
1501 printed only once and not everytime it fails (produces
1502 too much useless log). Affected file lib/silcutil/silclog.c.
1504 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1506 * Made the silc_server_daemonise() function more readable.
1507 Affected file silcd/server.c.
1509 * Pid file is now optional, the user may comment it out from
1510 the config file. Removed define SILC_SERVER_PID_FILE, we
1511 don't need a default any longer. Affected file
1512 configure.in.pre, lib/Makefile.am.pre.
1514 * Make some use of the pid file. The server now dies at startup
1515 if it detects a valid pid file on his path. The server would
1516 die anyway in this circumstance, because of the bind() failure.
1517 Affected file silcd/silcd.c.
1519 * No longer compiling lib/dotconf.
1521 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Fixed JOIN command parsing not to crash. Affected file
1524 lib/silcclient/command.c.
1526 * Fied the NICK_CHANGE notify to add the new client entry
1527 even it is resolved. This removes an <[unknown]> nick
1528 thingy bug in the client. Affected file is
1529 lib/silcclient/client_notify.c.
1531 * Do not try to allocate 0 bytes (efence does not like it)
1532 in lib/silccore/silccomand.c when encoding payload.
1534 * Do not take IRCNICK as nickname in Irssi SILC client since
1535 it is not possible to set nickname before hand connecting
1536 the server (TODO has an entry about adding auto-nicking
1539 * Changed the silc_server_command_pending to check whether
1540 there already exists an pending entry with the specified
1541 command, command identifier and pending callback. This is
1542 to fix IDENTIFY and WHOIS related crashes that may register
1543 multiple pending commands with same identifier. Affected
1544 file silcd/command.c.
1546 * Fixed the server to reconnect to the router even if it
1547 was already reconnecting and EOF was received. This to
1548 fix a possibility that the server wouldn't ever try to
1549 auto-reconnect to the router. Affected file silcd/server.c.
1551 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed the server's password authentication to use the
1554 length of the locally saved password, and not the one
1555 sent in the packet. Affected file silcd/protocol.c.
1557 * Fixed same password authentication problem in the
1558 Authentication Payload handling routines in
1559 lib/silccore/silcauth.c.
1561 * Yet another password authentication problem fixed with
1562 channel password handling in silcd/command.c.
1564 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * If first character of string in silc_parse_userfqdn is '@'
1567 then do not parse it. Affected file is
1568 lib/silcutil/silcutil.c.
1570 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Fixed minor bug in IDENTIFY command reply sending, which
1573 caused various weird problems during JOIN when it was
1574 resolving names for users. Affected file silcd/command.c.
1576 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Fixed the IDENTIFY command reply sending to chech better valid
1579 clients. It was possible to send incomplete list of replies.
1580 Affected file silcd/command.c.
1582 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Added silc_client_command[s]_[un]register functions now to
1585 dynamically register the commands in client library. Removed
1586 the static table of commands. This allows the client library
1587 to call commands without causing the application to know about
1588 what commands library has called.
1590 Removed the INFO command reply kludge to detect when the command
1591 was called by library. Now library use its own command reply
1592 function for INFO command.
1594 Added function silc_client_command_call to call a command.
1595 Application can use it to call command, not access the structure
1598 Now all commands that are sent by the client library (not
1599 explicitly sent by application) use own command reply functions.
1601 Affected files around lib/silcclient/ and in
1602 irssi/src/silc/core/.
1604 * Fixed the WHOIS command reply sending to chech better valid
1605 clients. It was possible to send incomplete list of replies.
1607 Fixed the WHOIS and IDENTIFY to send the request to router
1608 if normal server did not do it and did not find any results.
1610 Affected file silcd/command.c.
1612 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Moved the internal data from SilcClient context into its
1615 own file, not accesible to application. Affected files
1616 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1617 and other files in client library.
1619 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1621 * Added doc/examples installation target in Makefile.am.pre.
1624 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1627 commands the found client entry will be removed from the
1628 cache, after notifying application about the error. Affected
1629 file lib/silcclient/command_reply.c.
1631 * Changed the /MSG to check for exact nickname user gave, and
1632 not let `nick' match `nick@host' if it is only one found. Now,
1633 user must type the exact nickname (like nick@host2) even if
1634 there are no more than one same nicks found. This is to avoid
1635 a possibility of sending nickname to wrong nickname since
1636 `nick' could match `nick@host'. Affected file is
1637 irssi/src/core/silc-servers.c.
1639 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Do not print "you are now server operator" or similar when
1642 giving /away command. Affected files are
1643 irssi/src/silc/core/client_ops.c, silc-servers.h.
1645 * Made the silc_server_command_pending_error_check to send
1646 the same command reply payload it received back to the
1647 original sender of the command. This way all arguments
1648 that was received by the server will be received by the
1649 client too. Affected file silcd/command.c.
1651 * Added the silc_idcache_add to return the created cache entry
1652 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1654 * Add global clients to expire if they are not on any channel.
1655 This is because normal server will never know if they signoff
1656 if they are not on any channel. The cache expiry will take
1657 case of these entries. This is done by normal servers only.
1658 The affected files are silcd/command_reply.c,
1659 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1661 * If server receives invalid ID notification for WHOIS or
1662 IDENTIFY and the ID exists in the lists, it is removed.
1663 Affected file silcd/command_reply.c.
1665 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1666 in client then client entry that it matches is searched and
1667 the nickname is printed on the screen for user. Affected
1668 file irssi/src/silc/core/client_ops.c.
1670 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1672 * Use cache entry expire time in the LIST command reply to
1673 purge old entries from the cache after the LIST command
1674 reply has been received. This way we don't have non-existent
1675 entries in the cache for too long. Affected file is
1676 silcd/command_reply.c.
1678 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1680 * If we are normal server, and we've not resolved client info
1681 in WHOIS or IDENTIFY from router, and it is global client,
1682 we'll check whether it is on some channel. If it is not
1683 then we cannot be sure about its validity and will resolve it
1684 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1685 file silcd/command.c.
1687 * Search channel by name (if possible) rather than by ID
1688 in IDENTIFY command's command reply. Affected file is
1689 silcd/command_reply.c.
1691 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1694 Updated specs and implemented it. Affected file silcd/command.c,
1695 silcd/packet_send.c and silcd/packet_receive.c.
1697 * Implemented the <founder auth> payload handling in the JOIN
1698 command. If provided all conditions for channel joining
1699 except requirement to provide correct passphrase can be
1700 overrided by the channel founder. Updated the protocol specs.
1701 Affected file silcd/command.c.
1703 Added support for founder auth in JOIN command in client
1704 library. Fixed the parsing of the JOIN command now to support
1705 all options as they should be. The affected file is
1706 lib/silcclient/command.c.
1708 * Optimized the WHOIS and IDENTIFY commands to send the request
1709 to router only if it includes nicknames or other names. If
1710 they include only IDs then check the local cache first before
1711 routing. Affected file is silcd/command.c.
1713 * Added channels topic announcements. Affected file is
1714 silcd/packet_receive.c and silcd/server.c.
1716 * Fixed the silc_server_send_notify_topic_set to really destine
1717 the packet to channel. Affected file silcd/packet_send.c.
1719 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1720 library. Affected file lib/silcclient/client_notify.c.
1722 * Added UMODE announcements. Affected file silcd/server.c.
1724 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Memory leak fixes in:
1728 lib/silcutil/silcsockconn.c
1729 lib/silcske/silcske.c
1730 lib/silcske/groups.c
1732 lib/silccrypt/silcpkcs.c
1733 lib/silccore/silccommand.c
1734 lib/silccore/silcidcache.c
1739 * ROBOdoc documented the lib/silcske/groups.h file and a
1740 bit changed the interface for better.
1742 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1744 * Update the client entry context in the ID cache after
1745 nick change. Affected file lib/silcclient/command.c.
1746 Fixes the CUMODE command when regaining founder privileges,
1747 and a little WHOIS problem.
1749 * Fixed silc_net_gethostbyname to correctly call the
1750 inet_ntop. Affected file lib/silcutil/silcnet.c.
1752 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1754 * Added IPv6 support checking to the configure.in.pre, added
1755 also --enable-ipv6 option to override the check. Affected
1756 file configure.in.pre.
1758 * The silc_thread_create now calls the start function
1759 directly if threads support is not compiled in. Removes
1760 ugly #ifdef's from generic code. Affected files are
1761 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1763 * Added silc_net_gethostby[name/addr]_async to asynchronously
1764 resolve. Affected files are lib/silcutil/silcnet.[ch].
1766 * Added support for rendering IPv6 based server, client and
1767 channel IDs. Affected file lib/silcutil/silcutil.c.
1769 * Added support for creating IPv6 based server IDs. Affected
1770 file is silcd/serverid.c.
1772 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1774 * Added silc_net_gethostby[addr/name] into the
1775 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1776 routines. Added silc_net_is_ip[4/6]. Affected file is
1777 lib/silcutil/unix/silcunixnet.c. All routines that take
1778 address as argument now supports both IPv4 and IPv6 addresses.
1780 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1782 * Fixed LIST command reply sending in server. Affected file
1785 * Server now sends the kicker's client ID in the KICK notify
1786 to the kicked client. Affected file silcd/command.c.
1788 * The client library now parses the kickers client ID and
1789 UI displays it. Affected files lib/silcclient/client_notify.c
1790 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1792 * Made all payload parsing function prototypes consistent.
1793 They all take now const unsigned char * and uint32 pair as
1794 the payload data instead of SilcBuffer. Changes all around
1795 the source tree. Other unsigned char* -> const unsigned char*
1796 changes around the tree as well.
1798 * Optimized SFTP client and server packet sending not to
1799 allocate new buffer for each packet but to recycle the
1800 first allocated buffer. Affected files are
1801 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1803 * Optimized the SFTP client to use SilcList instead of
1804 SilcDList for requests, because it is faster. Affected file
1805 is lib/silcsftp/sftp_client.c.
1807 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1808 into lib/silccore/silcid.[ch].
1810 Renamed silcpayload.[ch] into silcargument.[ch].
1812 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * If client entry is deleted with active key agreement
1815 session, abort the session.
1817 The silc_client_abort_key_agreement now calls the completion
1818 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1820 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1823 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Don't use __restrict in older GCC's. Affected file is
1826 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1828 * silc_net_localhost now attempts to reverse lookup the
1829 IP/hostname. Affected file lib/silcutil/silcnet.c.
1831 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1832 command. It can be used to gain founder privileges at
1833 the same time when joining the channel.
1835 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1836 kicker's client ID as well. Updated protocol specs.
1838 Defined that the server must send SILC_COMMAND_IDENTIFY
1839 command reply with error status to client who sent
1840 private message with invalid client ID.
1842 Updated the protocol specification.
1844 * Added silc_server_send_command_reply to send any
1845 command reply. Affected file silcd/packet_send.[ch].
1847 * Added silc_id_payload_encode_data to encode ID payload
1848 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1850 * The server now send IDENTIFY command reply with error
1851 status if client ID in private message is invalid. Affected
1852 file silcd/packet_receive.c.
1854 * Save the server key file with server's IP address in
1855 the filename instead of hostname. The affected file is
1856 irssi/src/silc/core/client_ops.c.
1858 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1860 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1863 * Added libtool support for compiling shared objects in
1864 lib/silcsim. Affected file configure.in.pre and
1865 lib/silcsim/Makefile.am. Original patch by cras.
1867 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Pid file configuration, and server's config file fixes
1870 patch by toma. Updated CREDITS file.
1872 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Fixed silc_client_channel_message to not try to decrypt
1875 the message twice if it resolved the destination client
1876 information. This could cause of dropping one channel
1877 message. Affected file lib/silcclient/client_channel.c.
1879 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1882 lib/silcclient/client.c. This function is used when the SILC
1883 Client is run under some other scheduler, or event loop or
1884 main loop. On GUI applications, for example this may be
1885 desired to used to run the client under the GUI application's
1886 main loop. Typically the GUI application would register an
1887 idle task that calls this function multiple times in a second
1888 to quickly process the SILC specific data.
1890 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1892 * Fixed silc_server_drop() for dropping the supplementary
1893 groups as well, this could cause a security hole on some
1896 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1901 * Write PID file after dropping privileges. Added -F option
1902 to run server on foreground. A patch by debolaz.
1903 Affected files silcd/server.c, silcd/silcd.c.
1905 * Fixed MOTD to return the MOTD file server name. Affected
1906 file silcd/command.c.
1908 * Added INFO command reply handling to the Irssi SILC Client.
1909 Affected file irssi/src/silc/core/client_ops.c.
1911 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Fixed the silc_idcache_list_* routines to really support
1914 the dynamic list. Fixes a crash. Affected file is
1915 lib/silccore/silcidcache.c.
1917 * Fixed the LIST command reply to really call LIST command's
1918 pending callbacks. Affected file silcd/command_reply.c.
1920 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Update conn->local_entry->nickname after giving NICK
1923 command. Affected file lib/silcclient/command.c.
1925 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1927 * Added the [pid] option to the silcd configuration file
1929 Affected files: serverconfig.[ch] and silcd.c
1931 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Save fingerprint in WHOIS command reply in server.
1934 Affected file silcd/command_reply.c.
1936 * Fixed NICK commands pending callback registration.
1937 Affected file lib/silcclient/command.c.
1939 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Use ++server->cmd_ident when sending commands in server,
1942 instead of random number. Affected file silcd/command.c.
1944 * Fixed GETKEY command reply to call actually GETKEY pending
1945 command callbacks. Affected file silcd/command_reply.c.
1947 * A bit stricter check for nicknames. Check for same nickname
1948 in NICK command also. Affected file silcd/command.c.
1950 * Do not call INFO command everytime client ID changes, only
1951 during first connecting. Affected file lib/silcclient/client.c.
1953 * Set the new nickname only after successful command reply for
1954 NICK command is returned by server. Affected file
1955 lib/silcclient/command.c.
1957 * Remove nicknames from nicklist during server_signoff notify.
1958 Should fix /NAMES bit more. The affected file is
1959 irssi/src/silc/core/silc-channels.c.
1961 * Added `fingerprint' field to the SilcIDListData in the
1962 silcd/idlist.h to hold the fingerprint of the client's
1965 Send the fingerprint of the client's public key in WHOIS
1968 Affected files silcd/command.c, and silcd/idlist.[ch].
1970 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1971 create fingerprint from given data.
1973 * Show the fingerprint of the client's public key in WHOIS.
1974 Affected files irssi/src/module-formats.[ch] and
1975 irssi/src/silc/core/client_ops.c.
1977 * Format the multiple same nicknames also during JOIN and
1978 NICK_CHANGE notifys. Affected file is
1979 lib/silcclient/client_notify.c.
1981 * Do not print error on screen for invalid private message
1982 payload since it can come if someone is sending private
1983 messages with wrong key. Affected file
1984 lib/silccore/silcprivate.c.
1986 * Fixed multiple concurrent /PING crash. Affected file
1987 lib/silcclient/command.c.
1989 * Changed the wrong ID encoding. All IP addresses must be
1990 in MSB first order in encoded format. They were encoded
1991 wrong and was in LSB format. Affected files are
1992 silcd/serverid.c, lib/silcutil/silcutil.c.
1994 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1996 * Call the `connect' client operation through the scheduler
1997 in case of error. Affected file lib/silcclient/client.c.
1999 * Call the `failure' client operation even if the error
2000 occurred locally during a protocol. Affected file is
2001 lib/silcclient/protocol.c.
2003 * Added support of sending LIST command to router from normal
2004 server. This way normal server can get list of all channels
2005 in the network too. Fixed the channel list sending in the
2006 server too. Affected files are silcd/command.c, and
2007 silcd/command_reply.[ch].
2009 * Added silc_server_update_channels_by_server and
2010 silc_server_remove_channels_by_server. They are used during
2011 disconnection of primary router and in backup router protocol.
2012 Affected file silcd/server_util.[ch], silcd/server.c and
2013 silcd/server_backup.c.
2015 * Fixed channel adding to global list in IDENTIFY command
2016 reply in server. Affected file silcd/command_reply.c.
2018 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * If the incoming packet type is REKEY or REKEY_DONE process
2021 that packet always synchronously. Fixes yet another MAC
2022 failed error on slow (dialup) connections. Affected file
2023 lib/silcclient/client.c and silcd/server.c.
2025 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Call check_version SKE callback for initiator too. Affected
2028 file lib/silcske/silcske.c.
2030 * Implemented fix for security hole found in the SKE that was
2031 fixed in the specification few days back; the initiator's
2032 public key is now added to the HASH value computation.
2033 Added backwards support for the old way of doing it too, for
2034 old clients and old servers. Affected file is
2035 lib/silcske/silcske.c.
2037 * Enabled mutual authentication by default in SKE. If initiator
2038 is not providing mutual authentication the responder will
2039 force it. This will provide the proof of posession of the
2040 private key for responder. The affected files are
2041 lib/silcclient/protocol.c and silcd/protocol.c.
2043 * Do not cache anymore the server's public key during SKE.
2044 We do mutual authentication so the proof of posession of
2045 private key is done, and if the server is authenticated in
2046 conn auth protocol with public key we must have the public
2047 key already. Affected file silcd/protocol.c.
2049 * Added new global debug variable: silc_debug_hexdump. If
2050 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2051 file lib/silcutil/silclog.[ch].
2053 * Fixed compilation warning due to char * -> const char *.
2054 Affected files lib/silcutil/silcnet.h, and
2055 lib/silccore/silcauth.[ch].
2057 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Fixed CMODE command when new channel key was created. If
2060 the creation failed the old key was removed. Next time giving
2061 same command would crash the server since the old key was
2062 freed already. Affected file silcd/command.c.
2064 * Fixed the silc_server_announce_get_channels to not crash
2065 on reconnect. Affected file silcd/server.c.
2067 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Added silc_log_set_debug_string function to set a regex
2070 string to match for debug output. Only the function names,
2071 or filenames matching the given debug string is actually
2072 printed. This way it is possible to filter out those debug
2073 strings that user is not interested in.
2075 Fixed a bug in silc_string_regexify.
2077 Affected files lib/silcutil/silclog.[ch], and
2078 lib/silcutil/unix/silcunixutil.c.
2080 * Changed the -d options in both server and Irssi SILC client
2081 to take the debug string as argument. Affected files
2082 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2084 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Added silc_hash_babbleprint to create a Bubble Babble
2087 Encoded fingerprint. The encoding is developed by Antti
2088 Huima (draft-huima-babble-01.txt), and it creates human
2089 readable strings out of binary data. Affected file
2090 lib/silccrypt/silchash.[ch].
2092 * Print the babble print now in addition of fingerprint as well
2093 in Irssi SILC client. Affected files are
2094 irssi/src/fe-common/silc/module-formats.[ch],
2095 irssi/src/fe-common/silc/core/client_ops.c.
2097 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Fixed a security problem found in SKE. The initiator's
2100 public key too is now added to the HASH hash value creation
2101 which is signed by the responder to create the SIGN value.
2102 This will prevent anyone in the middle to lie to the responder
2103 about the initiator's public key. If this is done now, the
2104 man in the middle will get caught. Updated the protocol
2107 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Better installation directory handling. Configure module
2110 paths and other paths automatically to example_silc* files
2111 in doc/. A patch by toma.
2113 * Fixed compiler warning from MPI library, and from SILC RNG.
2116 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2117 It can be configured with ./configure. A patch by toma.
2119 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Find correct make to use in prepare-clean. A patch by
2122 toma. Affected file prepare-clean.
2124 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2126 * Added irssi variables use_auto_addr, auto_bind_ip,

2141 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Added silc_pkcs_public_key_compare to compare two
2144 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2146 * Check that the client who set the founder mode on the
2147 channel is the same client that is giving the founder
2148 mode to itself. It is done by comparing the saved public
2149 key (it is saved even in the authentication is passphrase).

2157 * Process the DISCONNECT packet through scheduler in the
2158 client library. Affected file lib/silcclient/client.c.
2160 * Fixed the silc_client_packet_parse to not to increase
2161 the packet sequence number if the conn->sock and the
2162 current socket connection is not same. This can happen
2163 for example during key agreement when the conn includes
2164 multiple socket connections (listeners). Affected file
2165 lib/silcclient/client.c.
2167 * The sender of the file transfer request now provides also
2168 the pointer (listener) for the key exchange protocol. If
2169 the listener cannot be created then it sends empty key
2170 agreement and lets the receiver provide the listener.
2172 Added `local_ip' and `local_port' arguments to the
2173 silc_client_file_send. If they are provided they are used,
2174 if not then it will attempt to find local IP address, if
2175 not found or bind fails then the remote client will provide
2178 Affected files are lib/silcclient/client_ftp.c and
2179 lib/silcclient/silcapi.h.
2181 * Extended the FILE SEND command to support defining the
2182 local IP and port for key exchange listener. They are

2187 * Defined to WHOIS command reply the sending of fingerprint
2188 of the client's public key (if the proof of posession of the
2189 corresponding private key is verified by the server).
2190 Updated to the protocol specification.
2192 * Added support of receiving the client's public key's
2193 fingerprint in command reply in client library. Affected
2194 file is lib/silcclient/command_reply.c, and
2195 lib/silcclient/idlist.[ch].
2197 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2250 client library. Affected file lib/silcclient/client_prvmsg.c.
2252 * Do not actually remove the client directly from ID cache
2253 during SERVER_SIGNOFF, but invalidate it. This way we
2254 preserve the WHOWAS info for the client. Affected file
2255 silcd/server_util.c.
2257 * Fixed SERVER_SIGNOFF notify handling in the server. The
2258 server is now able to process incoming SERVER_SIGNOFF notify
2259 for a server that it doesn't even know about. It will remove
2260 the clients provided in the notify. Affected file
2261 silcd/packet_receive.c.
2263 * Check for partial packet in data queue after every packet that
2264 was found from the queue. Return and wait for more data if
2265 there is partial data in queue. Affected file is
2266 lib/silccore/silcpacket.c.
2268 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2279 * Added better monitor of file transfers. It now monitors
2280 key agreement protocol during the file transfer too. Added
2281 error reporting too. Affected files
2282 irssi/src/silc/core/silc-servers.c,
2283 irssi/src/fe-common/silc/module-formats.[ch].
2285 * Wrote a help file for FILE command.
2287 * Added silc_rng_global_get_byte_fast to get not-so-secure
2288 random data as fast as possible. Random data is read from
2289 /dev/urandom if available and from the SILC RNG if not
2290 available. It is used in padding generation. Affected file
2291 lib/silccrypt/silcrng.[ch].
2293 * All packets in client library are now processed synchronously.
2294 Optimized packet processing a lot. Affected file
2295 lib/silcclient/client.c.
2297 * All server connection packets are processing synchronously
2298 now in server, to optimize packet processing. Affected file
2301 * Include files are installed now only in Toolkit distribution
2302 if make install is given. Affected files: all Makefile.am's.
2304 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Assure that silc_client_notify_by_server_resolve does not
2307 resolve the client information multiple times. If it cannot
2308 be found by the first it cannot be found at all. Affected
2309 file lib/silcclient/client_notify.c.
2311 * Fixed WHOWAS command reply calling. Affected file
2312 lib/silcclient/command_reply.c.
2314 * Removed all references to silc_idlist_get_client from the
2315 Irssi SILC client since that call is internal call used by
2316 the library. The Irssi SILC client will use now client
2317 retrieval functions found in silcapi.h.
2319 * Fixed a bug in resolving nickname info before sending
2320 private message. It used freed memory. Affected file
2321 irssi/src/silc/core/silc-servers.c.

2342 * Added silc_net_localip to return local host's IP address.
2343 Affected file lib/silcutil/silcnet.[ch].
2345 * If key exchange or rekey protocol is active for a connection
2346 parse all packets syncronously since there might be packets
2347 in packet queue that we are not able to process without first
2348 processing packets before them. Affected file silcd/server,
2349 lib/silcclient/client.c.
2351 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2352 whether library should continue processing the packet.
2353 Affected file lib/silccore/silcpacket.h.
2355 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2399 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2400 is incomplete and is being resolved, it won't be resolved
2403 Make sure also that USERS command reply does not resolve
2404 twice information. Affected file is
2405 lib/silcclient/command_reply.c.
2407 Make sure that silc_client_get_clients_by_list does not
2408 resolve twice same information.
2410 * Check for valid client->id in the silc_server_free_client_data.
2411 Affected file silcd/server.c.
2413 * Fixed /GETKEY nick@server not to crash if the server entry
2414 is not found. Affected file lib/silcclient/command.c.

2426 * Call the silc_server_udpate_servers_by_server in the
2427 primary router that comes back online in the backup resuming
2428 protocol. Otherwise it routes packets wrong. Affected file
2429 silcd/server_util.[ch], silcd/server_backup.c.
2431 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2434 lib/silcutil/silcbuffmt.[ch].
2436 * Redefined the SILC packet header to include the padding
2437 length. Affected file lib/silccore/silcpacket.[ch].
2439 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2440 length for maximum padding up to 128 bytes). Affected
2441 file lib/silccore/silcpacket.h.
2443 * Removed all backwards support for old 0.5.x MAC thingies.
2444 The SILC packet header change makes it impossible to be
2445 backwards compatible.
2447 * Send the ENDING packet with timeout in the backup resuming
2448 protocol. This is to assure that all routers has connected
2449 to the primary router. Affected file silcd/server_backup.c.
2451 * Changed the RNG to take the first IV from random data. It
2452 used to take it from zero actually. Changed the RNG also
2453 to use /dev/urandom during session. /dev/random is used
2454 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2456 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Changed the SILC packet header to have the first two bytes
2459 (the packet length) encrypted. Affected files aroung the
2460 code tree, lib/silccore/silcpacket.[ch]. Removed the
2461 SilcPacketCheckDecrypt callback. It is not needed anymore
2462 since the silc_packet_receive_process will determine now
2463 whether the packet is normal or special.
2465 * Implemented the unidirectional MAC keys. Affected files
2466 lib/silcske/silcske.c, silcd/protocol.c and
2467 lib/silcclient/protocol.c.

2474 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Allow backup router to announce servers. All servers
2477 announced by backup router are added to the global list
2478 automatically. Update hte server's socket to our primary
2479 router also when backup router announces a server.
2480 Affected file silcd/packet_receive.c.
2482 * Do not update the client->router in the function
2483 silc_server_udpate_clients_by_server if the client is on
2484 global list. We might fail to find any specific server
2485 for locally connected clients and local cell clients. They
2486 should still use the `from' and not `to' as client->router.
2487 This fixes backup router resuming protocol. Affected file
2488 silcd/server_util.c.
2490 * Decrease channel statistics count only if the channel
2491 deletion worked. Affected files are silcd/server.c and
2492 silcd/server_util.c.
2494 * Added silc_server_update_servers_by_server to update origin
2495 of all server entries. Used during backup router protocol.

2512 to the router it came from. Affected file is
2513 silcd/packet_send.c. Fixed memory leak too.
2515 * Announce informations for incoming router connection, but
2516 only after checking if it is replaced by backup router.
2517 Affected file silcd/packet_receive.c.
2519 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2521 * Fixed the backup resuming protocol to work in multiple
2522 router environment. Affected file silcd/server_backup.c.
2524 * Route packet only to one router in the function
2525 silc_server_packet_send_to_channel. Affected file is
2526 silcd/packet_send.c.
2528 * Fixed silc_server_send_notify_dest to set the broadcast
2529 flag. Fixed the silc_server_send_notify_topic to actually
2530 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2531 Affected file silcd/packet_send.c.
2533 * Changed the SFTP Filesystem interface. Changed the
2534 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2535 the filesystem operation function. The SilcSFTPFilesystem
2536 is now a context that is allocated by all filesystem allocation
2537 functions and it already includes the operations structure
2538 and filesystem specific context. It is given as argument
2539 now to the silc_sftp_server_start. This made the interface
2540 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2541 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2543 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Changed the backup router adding and getting interfaces
2546 in the server. The router that will be replaced by the
2547 specified backup router is now sent as argument. Affected

2558 and in silc_server_connect_to_router_final and remove the
2559 old entry if it exists. Affected file silcd/packet_receive.c,
2562 * Send the channel message always to only one router, either
2563 in upstream or downstream. Affected file is
2564 silcd/packet_send.c.

2600 send any data. Affected file lib/silcclient/client.c.
2602 * Implemented the backup router support when the primary router
2603 goes down. The servers and routers can now use the backup
2604 router as new primary router without loosing connectivity.
2606 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2609 in the server to indicate disabled entry. All data read
2610 from the connection will be ignored and no data is sent
2611 for entry that is disabled. Affected files are
2612 silcd/idlist.h, silcd/server.c.
2614 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2644 * Changed various routines in the core library to use the new
2645 silc_buffer_set instead of allocating new buffer only for
2648 * Added 64-bit value formatting and unformatting support to the
2649 silc_buffer_[un]format routines. Affected file is
2650 lib/silcutil/silcbuffmt.[ch].
2652 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2653 to includes/bitmove.h.
2655 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * Fixed channel user mode saving in client library. Affected
2658 file lib/silcclient/command[_reply].c.
2660 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Defined the file transfer to the SILC Protocol. Added
2663 new packet type SILC_PACKET_FTP and defined File Transfer
2664 Payload. The mandatory file transfer protocol is SFTP
2665 (SSH File Transfer Protocol). Affected file in addition
2666 of the internet draft is lib/silccore/silcpacket.h.
2668 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2669 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2670 is used as part of backup router protocol when the primary
2671 router of the cell is back online and wishes to resume
2672 the position as primary router.
2674 * Redefined the MAC generation keys in the protocol. The
2675 same key is not used anymore in both direction. Both
2676 direction will now use different keys for sending and
2677 receiving. This fixes a potential security flaw. This
2678 change causes incompatibilities in the protocol.
2680 * Redefined also the MAC computation from the packet.
2681 An packet sequence number is now added to the MAC
2682 computation. This prevents possible replay attacks against
2683 the protocol. This change too causes incompatibilities
2686 Added `sequence' field to the SilcPacketContext to hold
2687 the current sequence number for the packet.
2689 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Added `created' field to the SilcIDListData in the file
2692 silcd/idlist.h to indicate the time when the entry was
2695 * Added `created' field to the SilcChannelEntry too. Affected
2696 file silcd/idlist.h.
2698 * Added `creation_time' aguments to all the announcement functions
2699 in the server. If it is provided then only the entries that
2700 was created after the provided time frame are actually
2701 announced. Affected file silcd/server.[ch].
2703 * The protocol says that the Channel ID's IP address must be
2704 based on the router's IP address. Added check for this in
2705 the silc_server_new_channel when processing incoming New Channel
2706 Payload. Affected file silcd/packet_receive.c.
2708 * Print out the correct version with --version in SILC client.
2709 Affected file irssi/src/silc/core/silc-core.c.
2711 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2713 * Fixed WHOWAS command to check for completnes of the client
2714 entry always, not just when the command is coming from client.
2715 Affected file silcd/command.c.
2717 * Added new function silc_server_packet_queue_purge to purge the
2718 outgoing data queue to the network. After the function returns
2719 it is guaranteed that the outgoing packet queue is empty.
2720 Affected file silcd/packet_send.[ch].
2722 * Purge the outgoing packet queue in the rekey protocol's final
2723 callback to assure that all rekey packets go to the network
2724 before quitting the protocol. Affected file silcd/server.c.
2726 * Added silc_client_packet_queue_parse as similar function as
2727 in server to the client library. The affected file is
2728 lib/silcclient/client.c.
2730 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Splitted silcd/server.c and created silcd/server_util.[ch]
2733 for utility functions.
2735 * Added new socket flag SILC_SF_DISABLED to indicate that the
2736 connection is open but nothing can be sent to or received from
2737 the connection. Affected file lib/silcutil/silsockconn.[ch].
2738 The checking for disabled socket is checked in the low level
2739 silc_socket_write and silc_socket_read functions.
2741 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Allow only nicknames and channel names that fits into the
2744 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2746 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2748 * When processing JOIN command reply in server check that if
2749 the channel exists in our global list we'll move it the local
2750 list. Affected file silcd/command_reply.c.
2752 * Fixed the check whether client is joined on the channel already
2753 in JOIN command. Affected file lib/silcclient/command.c.
2755 * Fixed the JOIN command reply to check whether the channel
2756 already exists. Affected file lib/silcclient/command_reply.c.
2758 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2760 * Added silc_ske_status_string to map the SKE error numbers
2761 to readable strings. The affected files are
2762 lib/silcske/silcske[_status].[ch].
2764 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Do not show the private channels on the WHOIS channel list
2767 as it is not allowed by the protocol. The affected file is
2770 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Assure that the packet length digged from the actual packet
2773 is something sensible in the silc_packet_decrypt_rest_special
2774 in lib/silccrypt/silcpacket.c.
2776 * Free and NULL the allocated pointer in silc_hmac_alloc if
2777 the HMAC allocation fails. The affected file is
2778 lib/silccrypt/silchmac.c.
2780 * Print the selected security properties to the log files in
2781 the server. Affected file silcd/protocol.c.
2783 * Add SKE's reference counter even if calling the completion
2784 callback manually. Otherwise it goes negative, although it
2785 does not cause any problems. The affected file is
2786 lib/silcske/silcske.c.
2788 * Remove the client entry with short timeout after giving the
2789 KILL command. Affected file lib/silcclient/command.c.
2791 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2792 case all found clients are already disconnected (WHOWAS would
2793 found them) in the server. Affected file silcd/command.c.
2795 * Update the last_receive (time of last data received) to be
2796 updated only when received private or channel message so that
2797 the idle time showed in WHOIS makes more sense.
2799 * Added boolean field `valid' in to the SilcClientEntry in the
2800 client library to indicate whether the entry is valid or not.
2801 This fixes the nickname change bug on channel when changing
2802 the nickname to be same than the old (like nick to Nick) the
2803 nickname formatter doesn't set the new nick anymore to Nick@host.
2804 Affected file lib/silcclient/idlist.[ch].
2806 * Now actually fixed the nickname changing on disconnection.
2807 Added new function silc_change_nick to the Irssi SILC Client.
2808 Affected file irssi/src/silc/core/client_ops.c,
2809 irssi/src/silc/core/silc-nicklist.[ch].
2811 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2813 * Check that the public key exists in the GETKEY command before
2814 trying to encode it. Affected file silcd/command.c.
2816 * Print some notifications on received public keys with GETKEY
2817 command in the Irssi SILC Client. Affected files are
2818 irssi/src/fe-common/silc/module-formats.[ch],
2819 irssi/src/silc/core/client_ops.c.
2821 * Use IDENTIFY command to resolve the server information in the
2822 GETKEY command instead of INFO command. Affected file
2823 lib/silcclient/command.c.
2825 * All command reply functions in the client library now calls
2826 the pending command reply callbacks even if an error has
2827 occurred. The server has done this a long time and now it was
2828 time to move the client library to this as well. Now all
2829 errors can be delivered back to the pending command reply
2830 callbacks if necessary. Affected files are
2831 lib/silcclient/command[_reply].[ch].
2833 * Change the nickname on disconnection back to the username
2834 because in reconnect the server will enforce it to it anyway.
2835 Affected file irssi/src/silc/core/silc-servers.c.
2837 * Fixed a config file parsing bug in the Irssi SILC client.
2838 Affected file irssi/src/silc/core/clientconfig.c.
2840 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * When printing the channel mode on JOIN, verify that the
2843 channel key and channel's HMAC are valid. Affected file
2844 irssi/src/silc/core/client_ops.c.
2846 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2849 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2850 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2852 * Removed channel key rekey task deleting from the function
2853 silc_server_save_channel_key. Affected file silcd/server.c.
2854 Added explicit timeout task context instead that is used to
2855 delete the task if we are registering a new task before the
2856 new task has elapsed.
2858 * When channel key rekey occurs the client library now saves
2859 the old channel key for a short period of time (10 seconds) and
2860 is able to use it in case some is still sending channel
2861 messages encrypted with the old key after the rekey. Affected
2862 file lib/silcclient/[idlist.h|client_channel.c].
2864 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Added check to the silc_server_new_id_real to not accept
2867 new ID if it is the sender's own ID. Affected file is
2868 silcd/packet_receive.c.
2870 * Assure that we do not announce ourself or the one we've
2871 sending our announcements when we're router and are announcing
2872 servers to our primary router. Affected file silcd/server.c.
2874 * Fixed silc_server_command_identify_check_client to assemble
2875 correct WHOIS packet. It send corrupted WHOIS packet and
2876 caused problem with router to router connections. Affected
2877 file silcd/command.c.
2879 Fixed also silc_server_command_whois_check the same way
2880 as for the IDENTIFY command.
2882 * Added new SilcIDListStatus to the server in the SilcIDListData
2883 structure. The status now includes the current status of
2884 the entry (like registered, resolved etc.). Affected file
2885 silcd/idlist.[ch]. Defined a bunch of different status types
2886 as well. This replaced the old boolean registered field as well.
2888 Added resolve_cmd_ident field to the SilcClientEntry structure
2889 too so that if the entry is for example being resolved so
2890 another command may attach to the same pending command reply
2891 without requiring to resolve the same entry again. This concept
2892 should optimize the WHOIS and the IDENTIFY resolving under
2893 heavy load by taking away unnecessary resolving for entries
2894 that are being resolved already.
2896 Added support for adding multiple pending commands for one
2897 command idenfier. Affected file silcd/command[_reply].[ch].
2899 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2900 before deleting the data. Otherwise the hash table will have
2901 freed data in comparison functions. Affected file is
2902 silcd/command_reply.c.
2904 * Fixed silc_idlist_replace_client_id to add the new entry to
2905 the cache with NULL nickname. Otherwise there will be invalid
2906 memory as the nickname after the nickname is freed. Affected
2907 file silcd/packet_receive.c.
2909 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2910 saved into wrong slots because the previous number of entries
2911 was not taken into account. Affected file silcd/idlist.c.
2912 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2914 * If we are router and we receive JOIN notify to a channel that
2915 does not have any users then notified client is marked as the
2916 channel founder, as it is it. The affected file is
2917 silcd/packet_receive.c
2919 * Added to the extended hash table API's table_del_*ext functions
2920 the destructor as argument too, so that the caller can decide
2921 which destructor to use or whether to use destructor at all.
2922 Affected file lib/silcutil/silchashtable.[ch].
2924 * Fixed ID Cache purging. It actually deleted the entries from
2925 the hash table after the data was freed. The hash table ended
2926 up comparing freed memory. The affected file is
2927 lib/silccore/silcidcache.c.
2929 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Fixed Irssi SILC client's KILL command's HELP syntax.
2933 * The USERS command now resolves the detailed user information
2934 if the userinfo field is missing. Affected file is
2935 lib/silcclient/command_reply.c.
2937 * Do not print error in silc_file_read if the read file does
2938 not exist. Just silently return NULL. Affected file is
2939 lib/silcutil/silcutil.c.
2941 * Fixed the silc_log_output to not wine about NULL filename
2942 and to not create some bogus " " filename. Affected file is
2943 lib/silcutil/silclog.c.
2945 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2947 * Fixed various printing bugs on the user interface in the
2948 Irssi SILC Client. Minor changes that were forgotten from
2951 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Fixed the configure.in.pre and the compilation and distribution
2954 environment to support the new autoconf 2.52. That version is
2955 now required to compile the CVS trunk.
2957 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2960 to generally parse user@fqdn format strings. Affected file
2961 lib/silcutil/silcutil.c.
2963 * Added nickname_format and nickname_force_format fields to the
2964 SilcClientParams structure. The first one defines the format
2965 for the nicknames that the library will enforce if the receives
2966 multiple same nicknames. The second one is boolean value and
2967 can be used to force the library to always enforce the format
2968 to the nicknames regardles whether there are multiple nicknames
2969 or not. This configurable formatting was employed to flexibly
2970 support accessing multiple nicknames from the user interface.
2971 The userinterface can now set the nicknames to what ever format
2972 they prefer. Affected file lib/silcclient/silcapi.h.
2974 Added function silc_client_nickname_format to the file
2975 lib/silcclient/idlist.c. It performs the nickname formatting.
2977 Added new field `hostname´ to the SilcClientEntry context.
2978 It holds the hostname of the client. Affected file is
2979 lib/silcclient/idlist.h.
2981 * Irssi SILC Client sets the nicknames in nick@hostn format.
2982 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2983 irssi/src/silc/core/silc-core.c.
2985 The WHOIS printing now also shows both the real nickname and
2986 the formatted nickname so that user knows how to access the
2987 user if there are multiple same nicknames cached. Affected
2988 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2989 printing formatting too to take the hostname now as a separate
2990 argument. The Affected file is
2991 irssi/src/fe-common/silc/modules-formats.[ch].
2993 * Changed the silc_client_get_clients_local to accept the formatted
2994 nickname as argument. It accepts the real nickname too but the
2995 formatted nickname can be used to find the true entry from
2996 multiple entries. Affected file lib/silcclient/silcapi.h and
2997 lib/silcclient/idlist.c.
2999 * Added nickname_format_parse field to the SilcClientParams.
3000 It is a callback function provided by the application to parse
3001 the nickname out of the formatted nickname string. The library
3002 calls it to get the nickname from the formatted string. Since
3003 the application generally knows better the format of the nickname
3004 string it parses it instead of the library, even though library
3005 encodes the formatted string. If the callback function is not
3006 provided then the library will use the string as is. The
3007 affected file is lib/silcclient/silcapi.h.
3009 * All the nickname strings passed to the client library in
3010 commands are now expected to be formatted nickname strings.
3011 If the command does not support the formatted nickname string
3012 it will assume that the sent string is the actual nickname.
3013 Affected file lib/silcclient/command.c.
3015 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Added public key authentication support to OPER and SILCOPER
3018 commands in the client library. Affected file is
3019 lib/silcclient/command.c.
3021 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Changed the get_auth_methdod client operation to be asynchronous.
3024 It can be async if the application resolves the authentication
3025 method from the server during the negotiation. Added new
3026 SilcGetAuthMeth completion callback that the application will
3027 call after resolving the authentication method.
3029 Added function silc_client_request_authentication_method that
3030 the application can use to resolve the authentication method
3031 from the server. Added also SilcConnectionAuthRequest callback
3032 that the library will call after the server has replied. The
3033 application can call this function if it does not know the
3034 current authentication method.
3036 Affected files are lib/silcclient/client.c and
3037 lib/silcclient/silcapi.h.
3039 * The Irssi SILC client now automatically resolves the authentication
3040 method incase any configuration information is not present (and
3041 currently there never is). The affected file is
3042 irssi/src/silc/core/client_ops.c.
3044 * Fixed public key authentication from the client library.
3045 Affected file lib/silcclient/protocol.c. Changed also the
3046 protocol specification about the public key authentication in
3047 the connection authentication protocol. The actual data to be
3048 signed is now computed with a hash function before signing.
3050 * Fixed the public key authentication from the server as well.
3051 Affected file silcd/protocol.c.
3053 * Removed the mlock()'s from the memory allocation routines.
3054 Affected file lib/silcutil/silcmemory.c. The ./configure does
3055 not check anymore for the mlock(). Affected file is
3058 * Fixed USERS command in server to allow the execution of the
3059 command for private and secret channels if the client sending
3060 the command is on the channel. Affected file silcd/command.c.
3062 * Fixed silc_client_get_clients_local to return the clients
3063 count correctly. It could return wrong value. Affected file
3064 lib/silcclient/idlist.c.
3066 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3069 types. The assembler optimizations seemed not to like 64-bit
3070 data types. The assmebler optimizations thus are now enabled
3071 also for BSD systems as opposed to only enable them for Linux.
3073 * Do not check for threads at all on BSD systems. Affected
3074 file configure.in.pre.
3076 * Removed -n and -h options from the Irssi SILC Client since
3077 they are not used in silc.
3079 * Fixed the prime generation to assure that the first digit
3080 of the generated random number is not zero since our conversion
3081 routines does not like number strings that starts with zero
3082 digit. If zero digit is seen the random number is regenerated.
3083 This caused some corrupted RSA keys when the zero first digit
3084 was met. Affected file lib/silcmath/silcprimegen.c.
3086 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Fixed WIN32 configuration in the ./configure script.
3089 Fixed to include xti.h on environments that has it.
3090 Patches by Carsten Ilchmann and andrew.
3092 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Changed the silc_id_create_client_id to be collision
3095 resistant. It is now assured that there cannot be created
3096 two same client ID's. I suspect that some weird bugs in
3097 the server were actually caused by duplicate Client IDs.
3098 Affected file silcd/serverid.[ch]. A router receiving
3099 new ID now also assures and informs the sending server
3100 if the ID caused collision.
3102 * Changed the silc_id_create_channel_id to also assure that
3103 there are no collisions.
3105 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Statement about ignoring the Mutual Authentication flag when
3108 performing rekey with PFS was a bit misleading. It is ignored
3109 if it was set in the initial negotiation, it cannot be even
3110 set in the rekey. Fixed in the ke-auth draft. Started the
3111 new versions of the protocol drafts in the doc/.
3113 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Fixed a bug in silc_client_command_identify_save when saving
3116 new channel information. The channel name was no duplicated
3117 and caused crash on exit. Affected file is
3118 lib/silcclient/command_reply.c.
3120 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Fixed the getkey command handling in the server. Send just
3123 empty OK reply to the sender if the key could not be fetched
3124 (but everything else was ok, like the key just was not available).
3125 Changed the public key parameter to optional in the protocol
3126 specs so that empty OK reply can be sent. Affected file
3129 Added a message to Irssi SILC client to tell to user if the
3130 server did not return a public key.
3132 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Fixed a channel key regeneration bug. It registered new
3135 timeout tasks exponentially until all system resources were
3136 used. Affected file silcd/server.c.
3138 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Added the SILC Document generator to the scripts/silcdoc.
3141 It can be used to generate the Toolkit Reference Manual out
3142 of the source tree. Internally it will also use the RoboDoc
3143 generator now imported in util/robodoc.
3145 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Added couple of return's in rekey protocol if error orccurred
3148 during the protocol. The execution must be terminated.
3149 Affected file silcd/protocol.c. Also, terminate the protocol
3150 always with timeout.
3152 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * The client's Client ID was created initally from the wrong
3155 nickname (it could have been in format nick@host) in the
3156 silc_server_new_client. Affected file silcd/packet_receive.c
3158 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3160 * Added some SILC_LOG_ERROR's to various error conditions
3161 if client could not be added to ID cache. Affected files
3162 silcd/packet_receive.c and silcd/server.c.
3164 * When client's sock->user_data is freed, NULL also the
3165 client->router and client->connection pointers. Added check
3166 for these pointers being NULL to various places around the
3167 code. Affected file silcd/server.c.
3169 * Added client->data.registered == TRUE checks to various
3170 places around the code to assure that unregistered client's
3171 are not handled when it is not allowed. Affected file
3174 * Added `bool registered' fields to all
3175 silc_idlist_[server|client]_get_* routines to indicate whether
3176 the fetched client needs to be registered or not. Affected
3177 file silcd/idlist.[ch].
3179 * Add your own entry as registered to the ID cache in the
3180 server. Affected file server.c.
3182 * Fixed a bug in silc_server_new_server. The SilcServer was
3183 set as the new server's context instead of SilcServerEntry.
3184 This naturally caused some weird bugs.
3186 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Do not delete the channel rekey task when adding it
3189 for in silc_server_create_channel_key.
3191 * Changed the silc_server_create_channel_key to return
3192 TRUE or FALSE to indicate the success of the channel key
3195 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Fixed MSVC++ project files and added missing files to
3198 Makefiles under win32/.
3200 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Do not add TCP_NODELAY flag if the operating system
3203 does not have it defined. Affected files are
3204 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3206 * Fixed buffer overflow from Irssi SILC Client. Affected
3207 file irssi/src/fe-common/core/themes.c.
3209 * Fixed double free in client library in the file
3210 lib/silcclient/client.c when disconnecting from server.
3212 * Applied double free patch from cras to Irssi SILC client.
3213 Affected files irssi/src/core/[modules/expandos].c
3215 * Fixed the disconnection handling to Irssi SILC Client.
3216 The application must call silc_client_close_connection
3217 in ops->connect client operation in case of failure of
3218 the connection. Affected file is
3219 irssi/src/silc/core/client_ops.c.
3221 * Do not set sock->protocol to NULL in the function
3222 silc_client_close_connection after executing the protocol's
3223 final callback since the sock might not be valid anymore.
3224 Affected file lib/silcclient/client.c.
3226 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3228 * Do not enable SILC_THREADS if the linking with libpthread
3229 did not happen. Affected file configure.in.pre.
3231 * Added notion to protocol specification that server must
3232 verify the sent authentication payload with CMODE when
3233 setting the channel founder key. Implemented it to the
3234 server. Affected file silcd/command.c.
3236 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Added _EXTRA_DIST SILC distribution variable to the
3239 distributions file. It is used to conditionally add extra
3240 files or directories to the specific distribution. Affected
3241 files ./prepare, Makefile.am.pre and distributions.
3243 Removed the `_' from the start of the distribution names.
3246 * Added README.WIN32 for instructions to compile the Toolkit
3249 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3251 * Fixed a double free in disconnection in the server. Affected
3252 file is silcd/server.c.
3254 * Fixed the lib/silcske/groups.c to work now also with GMP
3255 MP library. The string conversion did not work when using
3256 specific base and the base is indicated in the string as well.
3258 * Created win32/ directory which now includes MSVC++ specific
3259 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3260 It will appear only in the toolkit distribution
3262 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Changed the key material distribution function in case when
3265 the hash output is too short. The data is now concatenated
3266 a bit differently than it used to. Made the change to the
3267 SKE protocol specification.
3269 * Added better GMP detection to configure.in.pre. A patch
3272 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Fixed a minor bug in SKE that might cause some problem on
3275 some platforms. Affected file lib/silcske/silcske.c.
3277 * Added the cookie checking for initiator in the SKE. It checks
3278 that the responder returns the sent cookie unmodified. The
3279 affected file is lib/silcske/silcske.c. Added new SKE
3280 error type INVALID_COOKIE that can be sent during the
3281 negotiation. Fixed some memory leaks as well.
3283 * Added the "invalid cookie" error message to Irssi SILC client's
3286 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3288 * Added `task_max' field to the SilcClientParams to indicate
3289 the maximum tasks the scheduler can handle. If set to zero,
3290 default values are used. Affected file lib/silcclient/silcapi.h.
3292 * Fixed memory leaks in silc_client_close_connection. Affected
3293 file lib/silcclient/client.c.
3295 * Added silc_client_del_client_entry to client library to free
3296 all memory of given client entry. Affected file is
3297 lib/silcclient/idlist.[ch].
3299 * Added new functions silc_client_del_channel and
3300 silc_client_del_server to delete channel and server entries.
3301 Affected file lib/silcclient/[silcapi.h/idlist.c].
3303 * Removed silc_client_del_client_by_id from silcapi.h.
3305 * Fixed the INFO command to return the server's own info
3306 correctly when querying by Server ID. Affected file is
3309 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Removed the non-blocking settings in WIN32 code in the
3312 silc_sock_[read/write] and added SleepEx instead. Affected
3313 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3314 of input data is now checked with FIONREAD and ioctlsocket.
3316 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Call silc_schedule_task_del_by_context in the
3319 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3320 Affected file lib/silccore/silcprotocol.c.
3322 * Call silc_protocol_cancel for active protocols in the
3323 silc_server_close_connection if the funtion
3324 silc_server_free_sock_user_data has not been called.
3325 Affected file silcd/server.c.
3327 * Generic tasks cannot be deleted using the del_by_fd
3328 task deleting function since generic tasks does not match
3329 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3331 * Added a notion to SILCOPER help file that the SILCOPER works
3332 only on router server, not on normal server.
3334 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * Added for WIN32 support for the new scheduler as well.
3337 Affected file lib/silcutil/win32/silcwin32schedule.c.
3339 * Fixed the SHA1 implementation to work on various platforms.
3341 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3344 API. It is part of the scheduler now. Everything else is
3345 as previously but some functions has changed their names.
3346 Checkout the lib/silcutil/silcschedule.h for the interface.
3347 Updated all applications to use the new interface. Affected
3348 files are lib/silcutil/silcschedule.[ch].
3350 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Found a bug in the SKE implementation. The HASH value,
3353 specified by the protocol, was not computed correctly. The
3354 public key of the responder was not added to the computation
3355 even though it is mandatory. Affected file lib/silcske/silcske.c.
3356 This unfortunately causes incompatibilities with older
3357 clients and servers.
3359 * Added WIN32 specific network init and uninit functions:
3360 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3361 the Winsock2. Affected file lib/silcutil/silcnet.h and
3362 lib/silcutil/win32/silcwin32net.c.
3364 * Set the socket always to nonblocking mode on WIN32 after
3365 reading data or writing data. Affected file is
3366 lib/silcutil/win32/silcwin32sockconn.c.
3368 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3370 * Fixed various compilation problems under WIN32. Affected
3371 files lib/silcutil/win32/silcwin32thread.c and
3372 lib/silcutil/win32/silcwin32schedule.c.
3374 * Removed all _internal.h #includes from public header
3375 files. Internal headers must never be included from
3378 Removed also the lib/silcske/payload_internal.h file.
3380 * All include files that may be needed (public and some others
3381 included by the public headers) by application developers are
3382 now copied to the ./includes directory. It does not copy any
3383 internal headers. Affected file Makefile.defines.pre and all
3384 Makefile.am's under lib/ and subdirs.
3386 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Do not change the ~/.silc directory's permissions automatically.
3389 Affected file irssi/src/silc/core/clientutil.c.
3391 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Do not cancel the protocol in silc_server_close_connection
3394 it might cause recursion. Now cancelled in the function
3395 silc_server_free_sock_user_data. Affected file silcd/server.c.
3397 * Fixed the silc_server_remove_clients_by_server to regenerate
3398 the channel keys correctly finally. Added also new function
3399 silc_server_remove_clients_channels to actually do it.
3400 Affected file silcd/server.c.
3402 * Fixed the silc_server_new_channel to not crash by giving
3403 wrong router to the new channel. Affected file is
3404 silcd/packet_receive.c.
3406 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3409 which is given as argument to the silc_client_alloc now.
3410 It can be used to configure the client and set various parameters
3411 that affect the function of the client.
3413 * The USERS command in server did not check whether the channel
3414 is private or secret. Affected file silcd/command.c.
3416 * Added new argument to the USERS command in protocol specification.
3417 The USERS command now can take the channel name as argument
3418 as well. Added support for this in client and server and
3419 updated the protocol specs.
3421 * Completed the GETKEY command in client. It can be now used
3422 to fetch also servers public key not only some clients.
3423 Affected files lib/silcclient/command[_reply].c.
3425 * Added silc_client_get_server to return server entry by the
3426 server name. Affected files lib/silcclient/silcapi.h and
3429 * Redefined the IDENTIFY command in protocol specification to be
3430 more generic. It now can be used to query information about
3431 any entity in the SILC Network, including clients, servers and
3432 channels. The query may be based either the entity's name
3433 or the ID. Added support for this in both client and server.
3435 Affected files silcd/command.c and lib/silcclient/command.c
3436 and command_reply.c.
3438 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3439 the _from_client and _from_server functions. Affected file
3442 * Added silc_client_get_channel_by_id_resolve to the file
3443 lib/silcclient/silcapi.h to resolve channel information by
3444 its ID. Added also silc_client_get_channel_by_id that
3445 does not resolve it from the server.
3447 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3449 * Added SilcServerEntry context into the client library
3450 to represent one server. The INFO command now allocates
3451 these to save the resolved server info. For now on the
3452 client library will also keep information about servers,
3453 connected and resolved with INFO.
3455 The INFO command now allocates the SilcServerEntry context
3456 and saves the server info there. The COMMAND_REPLY in
3457 the INFO now returns the parameters to application in
3458 same order as defined in the protocol specification.
3460 The entries are cached in the client->server_cache.
3462 * The INFO command is now issued after received the Client ID
3463 from the server. Affected file lib/silcclient/client.c.
3465 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3466 to the application as the mode changer might be server.
3467 It is guaranteed that NULL is not returned anymore to the
3468 application. Affected file lib/silcclient/client_notify.c.
3470 The ID Type is now also passed to the application so that
3471 it can check whether the returned entry is SilcClientEntry
3474 Added new function silc_client_get_server_by_id to return
3475 the server entry by ID. Affected files are the
3476 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3478 * Do not create the channel in the Irssi SILC Client when issuing
3479 the JOIN command but when received the sucessful JOIN command
3480 reply. Otherwise the channel might get created even though we
3481 could not join it. The Affected file is
3482 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3484 * Fixed a channel joining bug in router. The router must also
3485 check the channel modes, invite and ban lists etc. when serving
3486 the JOIN command sent by normal server. Affected file is
3487 silcd/command.c. The router now resolves the client's
3488 information from the server who sent the JOIN command if it
3489 does not know it, and processes the JOIN command only after
3492 * Changed the SilcCommandCb to take new argument; void *context2.
3493 Affected file lib/silccore/silccommand.h
3495 The second argument in the command callbacks in the server now
3496 includes the SilcServerCommandReplyContext if the command was
3497 called as pending command callback from the command reply.
3498 Otherwise it is NULL. When called as pending the status of the
3499 command reply will be checked and if it was erronous the
3500 error will be sent to the original sender of the command.
3501 This way the client always receives the error messages even
3502 though the server was actually the one who received the error
3503 when it resent the command to router, for example. Affected
3504 files silcd/command[_reply].[ch].
3506 * Fixed sending WHOWAS command's error message to client if
3507 the requested client could not be found. It was missing.
3510 * Changed the CMODE and CUMODE commands reply arguments in the
3511 protocol specification. The Channel ID is now sent in both
3512 of the commands to identify the channel. Implemented this
3513 new feature to the client and server. Affected files
3514 lib/silcclient/command_reply.c and silcd/command.c.
3516 * Made better checks for invite and ban lists in the JOIN
3517 command in server. Affected file silcd/command.c.
3519 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3521 * The server now performs the incoming host IP/DNS lookup
3522 using the silc_socket_host_lookup and thus does not block
3523 the server anymore. Affected file silcd/server.c.
3525 * Completed the multi-thread support for SILC Scheduler in
3526 the lib/silcutil/silcschedule.c.
3528 * Fixed the configure.in.pre to detect the pthread correctly
3531 * Fixed a deadlock in silc_task_queue_wakeup in the file
3532 lib/silcutil/silctask.c.
3534 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3536 * Added new function silc_schedule_wakeup that is used in
3537 multi-threaded environment to wakeup the main thread's
3538 schduler. It needs to be used when a thread adds a new task
3539 or removes a task from task queues. After waking up, the
3540 scheduler will detect the task queue changes. If threads
3541 support is not compiled in this function has no effect.
3542 Implemented the wakeup mechanism to both Unix and WIN32
3543 systems. Affected files are lib/silcutil/silcschedule.[ch],
3544 lib/silcutil/unix/silcunixschedule.c and the
3545 lib/silcutil/win32/silcwin32schedule.c.
3547 * Added new function silc_task_queue_wakeup to wakeup the
3548 scheduler by the specified task queue. Affected file
3549 lib/silcutil/silctask.[ch].
3551 * The silc_socket_host_lookup_start now wakes up the scheduler
3552 after adding the timeout task. Affected file is
3553 lib/silcutil/silcsockconn.c.
3555 * The silc_socket_host_lookup is synchronous now if the threads
3556 support is not compiled in. However, the callback is still
3557 called asyncronously through the scheduler, anyway. Affected
3558 file lib/silcutil/silcsockconn.c.
3560 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Added new function silc_socket_host_lookup to perform
3563 asynchronous IP and FQDN lookups for the socket connection.
3564 Affected files lib/silcutil/silcsockconn.[ch].
3566 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3568 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3569 that may or may not compile the mutex support in.
3571 Changed the silc_mutex_alloc interface. It allocates the
3572 mutex now to the sent pointer and returns TRUE or FALSE.
3574 Affected file lib/silcutil/silcmutex.h.
3576 * Wrote the SILC Task Queue interface to support multi-threads.
3577 Affected file lib/silcutil/silctask.[ch].
3579 * Wrote the SILC Scheduler to support multi-threads. Affected
3580 file lib/silcutil/silcschedule.c.
3582 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3584 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3585 in lib/silcutil/win32/.
3587 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3589 * Defined SILC Mutex API and SILC Thread API and implemented
3590 them for Unix. Affected files are
3591 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3592 lib/silcutil/unix/silcunixmutex.c and
3593 lib/silcutil/unix/silcunixthread.c.
3595 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Fixed the silc_server_remove_clients_by_server's channel
3598 key re-generation. The hash table handling was incorrect
3599 and would not work with many channels. Affected file is
3602 * Fixed some memory leaks around the server code.
3604 * Rewrote the silc_server_get_users_on_channel to support IPv6
3605 based Client ID's. Affected file silcd/server.c.
3607 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3608 specification. However, a separate document must be written
3609 to define the detailed signing procedure and the payload
3610 associated with the flag. Defined the flag to the
3611 lib/silccore/silcchannel.h as well.
3613 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Changed the dynamic tables to static size tables in the
3616 lib/silccrypt/silchmac.c.
3618 * Removed GCC dependencies from the code. A patch by cras.
3620 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3622 * Do not show the error "Error receiving packet bla bla"
3623 in server if it really was not an error (-2 means that reading
3624 is pending). Affected file silcd/server.c.
3626 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Fixed a possible crash in silc_server_remove_clients_by_server
3629 in silcd/server.c. Fixed there also some memory leaks.
3631 * Fixed the silc_idlist_replace_client_id. It could replace
3632 wrong key in the hash table. Affected file silcd/idlist.c.
3634 * Do not check whether there are global users on the channel
3635 if the channel->global_users is FALSE. Affected functions
3636 silc_server_remove_from_one_channel and
3637 silc_server_remove_from_channels in silcd/server.c. Also,
3638 do not check if the removed client is local as we can be
3639 sure that global client was not removed from the channel
3640 and checking for global users is not needed.
3642 * The silc_server_remove_clients_by_server now re-generates
3643 the channel keys correctly for those channels that had
3644 clients removed from them. Affected file silcd/server.c.
3646 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3648 * Found the reason of random crashes in the server. We weren't
3649 ignoring the SIGPIPE signal (which can be sent in write())
3650 and it crashed the server. Affected file silcd/silcd.c.
3652 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Assure that sock->user_data is not NULL in the function
3655 silc_server_packet_send in silcd/packet_send.c.
3657 * Disconnect the remote connection if it could not be added
3658 to any ID lists in the server. The affected file is
3661 * Check in silc_server_packet_send[_real/dest] that the
3662 socket is not disconnecting and ignore the data if it is.
3663 Affected file silcd/packet_send.c.
3665 * Define inline to __inline on native WIN32 compilation.
3666 Affected file includes/silcwin32.h.
3668 * Added some explicit type casts for inline code since MSVC
3669 require them. Affected files lib/silcutil/silcbuffer.h,
3670 lib/trq/silcdlist.h and lib/trq/silclist.h.
3672 * Print warning in log files from now on if the packet
3673 decryption fails. Affected file silcd/server.c.
3675 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3677 * Changed the `say' client operation's interface to accept
3678 new `type' argument to indicate the type of the message sent
3679 by the library. The application may filter the library's
3680 messages according the type. The affected file is the
3681 lib/silcclient/silcapi.h.
3683 * Added two new functions to lib/silcclient/silcapi.h:
3684 silc_client_del_client and silc_client_del_client_by_id.
3685 Affected file lib/silcclient/idlist.c.
3687 * Moved the clientincludes.h from includes/ to silc/ and
3688 serverincludes.h from includes/ to silcd/.
3690 * The modes for the CMODE and CUMODE are now passed as
3691 uint32 for application with COMMAND_REPLY. The affected
3692 file is lib/silcclient/command_reply.c.
3694 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * /WHOIS without arguments shows client's own information.
3697 Affected file lib/silcclient/command.c.
3699 * Changed PING to not accept any arguments. The specs
3700 says that client can ping only the connected server so
3701 requiring an argument is not needed. Affected file is
3702 lib/silcclient/command.c.
3704 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * Fixed a fatal bug in private message sending and reception
3707 encryption and decryption when using private message keys.
3708 The implementation was incorrect and did not follow the
3709 specification. It causd that some of the message were
3710 lost since it did not use the sending and receiving keys
3711 as the protocol suggests. This has been fixed and will cause
3712 incompatibilities with older clients when sending private
3713 message encrypted with private message keys. Affected files
3714 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3715 and various other in Irssi SILC Client.
3717 Added `responder' boolean argument to the functions
3718 silc_client_add_private_message_key[_ske] to indicate when
3719 the key is added as responder or initiator of the key
3722 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3724 * Removed the silc_ske_check_version function and created
3725 a SilcSKECheckVersion callback. Added also a function
3726 silc_ske_set_callbacks that is now used to set all SKE
3727 callbacks. The callback functions are not given to
3728 the SKE functions anymore, but this function is used to
3731 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3733 * Added `silc_version' argument to the silc_client_alloc
3734 to define the version of the application for the library.
3735 The library will use the version string to compare it
3736 against the remote host's (usually a server) version
3737 string. Affected file lib/silcclient/silcapi.h
3739 * Added the KE protocol context to Key Agreement context
3740 in client library so that we can abort the SKE if it
3741 is in process when we get timeout. Affected file is
3742 lib/silcclient/client_keyagr.c.
3744 * Do not resolve the client ID forever if it returns in the
3745 first time that such client does not exist. This was done
3746 for example with private message. Affected file is
3747 lib/silcclient/client_prvmsg.c.
3749 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3751 * Do not add regex.h for WIN32. The affected file
3752 includes/silcincludes.h.
3754 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3755 not work yet 100%. It generates the DLL's automatically
3756 when compiling with --with-win32 under cygwin.
3758 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3760 * lib/contrib/regex.c is not compiled on WIN32.
3762 * Added silc_net_get_socket_opt function to the
3763 lib/silcutil/silcnet.h.
3765 * Added includes/silcwin32.h for WIN32 specific includes
3768 * Do not use ptime structure or any of the posix process
3769 functions on WIN32 in lib/silccrypt/silrng.c.
3771 * Added silc_gettimeofday to provide generic function
3772 for struct timeval on all platforms. Added the function
3773 to lib/silcutil/silcutil.h.
3775 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3778 library as they clearly belong there. As a plus side we
3779 can make the actual socket connection routines platform
3782 Added also new generic function silc_socket_read and
3783 silc_socket_write (that used to be silc_packet_[read/write].
3784 The implementation of these are platform specific.
3786 * Added WIN32 specific routines of silc_socket_[read/write]
3787 to lib/silcutil/win32/silcwin32sockconn.c.
3789 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3791 * Added preliminary support for native WIN32 compilation under
3792 cygwin (using the -mno-cygwin option for GCC) to the
3793 ./configure.in.pre. The --with-win32 now prepares the
3794 compilation for native WIN32.
3796 * Rewrote the SILC Scheduler interface in the file
3797 lib/silcutil/silcschedule.h. The scheduler is now context
3798 based and does not have anymore any global static scheduler.
3799 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3800 and created lib/silcutil/win32 directory for WIN32 based
3803 * Added Unix specific network routines to the
3804 lib/silcutil/unix/silcunixnet.c and the old
3805 lib/silcutil/silcnet.c includes now only generic routines.
3807 Added WIN32 specific network routines to the
3808 lib/silcutil/win32/silcwin32net.c.
3810 * Added Unix specific utility functions from the
3811 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3813 * Added WIN32 SILC Scheduler to the file
3814 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3817 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3819 * Do not handle JOIN notify in the server if the target client
3820 is not registered (idata->registered == FALSE). The affected
3821 file is silcd/packet_receive.c.
3823 * Update the nickrec->founder in event_cumode in the Irssi SILC
3824 client. Affected file irssi/src/silc/core/silc-channels.c.
3826 * Fixed the CUMODE_CHANGE notify handling in the server when
3827 server and router are announcing their clients on channels.
3828 Now the mode changes are saved and notified correctly. The
3829 affected file is /silcd/packet_receive.c.
3831 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3832 They really did not replace the cache entry in the ID Cache.
3833 Now they do that. Affected file silcd/idlist.c.
3835 * Fixed the KICK notify handling in the Irssi SILC client to
3836 update the channel records so that the kicked client does not
3837 appear to be on the channel. The affected file is
3838 irssi/src/silc/core/silc-channels.c.
3840 * Always update the conn->current_channel when executing command
3841 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3843 * Fixed the KILL notify handling in Irssi SILC client to remove
3844 the killed client on all channels.
3846 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Fixed the silc_parse_command_line to remove extra spaces
3849 from the start and end of the arguments. Affected file is
3850 lib/silcutil/silcutil.c.
3852 * Cancel and free any active protocol in the function
3853 silc_server_close_connection. Affected file silcd/server.c.
3855 * Cancel and free any active protocol in the function
3856 silc_client_close_connction. Affected file is
3857 lib/silcclient/client.c.
3859 * Do not execute the KILL command for clients that are in
3860 history (ie. they are not in the network). Affected file is
3863 * Fixed KILL notify handling, client does not crash anymore.
3864 Affected file irssi/src/silc/core/silc-channels.c.
3866 * Reduced the default packet buffer size from 2048 to 1024 in
3867 lib/silccore/silcpacket.c.
3869 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3870 counter to the SKE context that is incresed when the SKE library
3871 performs async operation outside the library. If the outside
3872 process frees the SKE context and FREED status will be set
3873 and the library will detect after the sync operation that the
3874 libary is freed. The affected files are
3875 lib/silcske/silcske[_status].[ch].
3877 * Resolve the client entry information in the function
3878 silc_client_channel_message to assure that NULL pointer is not
3879 passed as client entry to the application. */
3881 * Fixed the task timeout calculation to assure that there is
3882 never negative timeouts. The affected file is
3883 lib/silcutil/silcschedule.c.
3885 * Fixed the channel user mode notification sending in server.
3886 It was sent point-to-point to the router (or to server by router)
3887 but it needs to be destined to a channel. The routines now
3888 supports sending the channel user mode notifys to the channels
3889 when announcing clients and channels. Affected files are
3890 silcd/server.c and silcd/packet_receive.c.
3892 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3893 It did not actually replace the old channel entry in the cache.
3894 Affected file lib/silcclient/client_notify.c.
3896 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Fixed a possible crash in silc_packet_send_prepare. It now
3899 assures always that there is enough space in the buffer and
3900 at the tail area of the buffer (for MAC).
3902 Fixed the inbound buffer reallocation in silc_packet_read.
3903 It was old code and did not handle the reallocation correctly.
3906 The affected file is lib/silccore/silcpacket.c.
3908 * Fixed buffer overflow in silc_parse_nickname in the file
3909 lib/silcutil/silcutil.c.
3911 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * make install generates new server keys only if there is not
3916 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3919 Added check that if the NOREPLY is set then we will not send
3920 the away message. This avoids infinite loop of away messages
3921 if both clients are away. The affected file is
3922 lib/silcclient/client_prvmsg.c.
3924 * Fixed client crash if /NICK was given without arguments.
3925 Affected file lib/silcclient/command.c.
3927 * Server does not send the invite list in INVITE command back
3928 to the client if the list was not altered. Added this notion
3929 to the protocol spec as well. Affected file silcd/command.c.
3931 Fixed possible crash in INVITE command by checking the
3932 value of silc_server_get_client_route command.
3934 * Fixed the INVITE notify type handling. The arguments are now
3935 taken in correct order and client does not crash. The affected
3936 file is irssi/src/silc/core/silc-channels.c.
3938 Removed the "Inviting xxx to channel" message from the
3939 client library away and let the application handle it.
3940 Affected file lib/silcclient/command.c. Added that message
3941 to Irssi SILC client's message formats.
3943 * Fixed CMODE command crash in client. It now checks the
3944 amount of arguments correctly and does not crash. The affected
3945 file is lib/silcclient/command.c.
3947 * Do not create new channel automatically in silc_channels_join
3948 but check whether the channel by that name already exists.
3949 Affected file irssi/silc/core/silc-channels.c.
3951 * Do not send the SERVER_SIGNOFF to router if the disconnected
3952 entity was the router. Affected file silcd/server.c.
3954 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3955 SILC client as it was missing from there.
3957 Added the handling of the KICK notify to the Irssi SILC client
3958 as it was missing. Added "you have been kicked" message to
3959 Irssi SILC client's message modules formats.
3961 Added the handing of the KILL notify to the Irssi SILC client
3962 as it was missing. Added the kill message module formats
3965 The affected file is irssi/src/silc/core/silc-channels.c.
3967 * The router did not save the channel mode the server announced.
3968 Affected file silcd/packet_receive.c.
3970 * Fixed a possible crash in INFO command in server. If the
3971 server did not provide the server info it crashed. Affected
3972 file silcd/command.c.
3974 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Fixed the GETKEY command in the server to check also the
3977 global list. Otherwise the GETKEY would not work correctly
3978 in normal SILC server. Affected file silcd/command.c.
3980 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Fixed GETKEY crash, it crashed if the command did not succseed.
3984 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3987 is now real and not just an macro interface to GMP.
3989 Removed the entire GMP from the source tree and imported new
3990 NSS MPI library instead. Reason for removing GMP is that it is
3991 extremely large and compiles extremely slow. The NSS MPI
3992 is only a few files and compiles in less than 10 seconds.
3993 The speed is also about the same as GMP. The MPI is imported
3994 to lib/silcmath/mpi.
3996 If the system has GMP installed we will still use the GMP.
3997 If it is not then the NSS MPI will be compiled.
3999 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Merged a long nickname (127 characters long) crash bugfix from
4002 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4004 * Merged a freed memory reference bugfix from Irssi CVS tree.
4005 Affected file irssi/src/core/commands.c.
4007 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Added the server's public key sving and verification to the
4010 server when performing the SKE. This was missing and the
4011 remote server's (or router's) public key was accepted without
4012 checking whether we have it previously or trust it at all.
4013 Affected file silcd/protocol.c.
4015 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Check in the silc_server_timeout_remote if protocol is active
4018 and make sure that the protocol's final callback is called so
4019 that all memory if freed. Affected file silcd/server.c.
4021 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * silc_server_whois_send_reply crashed the server if the nickname
4024 was 127 characters long. Affected file silcd/command.c.
4026 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Added sanity check to the silc_server_new_client. If the hostname
4029 is provided inside username then check that the provided hostname
4030 really is the same as the resolved one. If the hostname was not
4031 resolved then check it from the public key. Affected file is
4032 silcd/packet_receive.c.
4034 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4035 if the server disconnected us and the connection is not valid
4036 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4038 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4039 the library to the lib/silcutil/silcutil.[ch].
4041 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Close log file after open. Affected file
4044 lib/silcutil/silclog.c.
4046 * Check whether sock == NULL in silc_client_send_packet and return
4047 if it is. Affected file lib/silcclient/silcclient.c.
4049 * Check rec->entry == NULL in the Irssi SILC Client before
4050 sending the channel message. Affecte file is
4051 irssi/src/silc/core/silc-servers.c.
4053 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Merged a splitted window bugfix from Irssi CVS tree. The
4056 affected file is irssi/src/fe-text/textbuffer-view.c.
4058 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4059 It did not print nickname.
4061 * Improved the distributions system a bit.
4063 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4066 irssi/src/fe-text/gui-window.c.
4068 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4069 to in-active server. The affected file is
4070 irssi/src/silc/core/client_ops.c.
4072 * Resolve the client in USERS command reply if the entry does
4073 not have username resolved. The affected file is
4074 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4075 command to WHOIS command to really resolve stuff. The USERS
4076 is not used any more in any critical section so WHOIS can
4077 be used even though it might be slower than IDENTIFY.
4079 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4082 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Changed the protocol API a bit more consistent in the
4085 lib/silccore/silcprotocol.[ch].
4087 * Changed the following headers to ROBODoc format:
4089 lib/silccore/silcpayload.h
4090 lib/silccore/silcprotocol.h
4091 lib/silccore/silcsockconn.h
4093 All core library headers are now formatted.
4095 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Fixed a bug in Irssi SILC client; do not show that you are
4098 server/router operator if you really are not. Affected file is
4099 irssi/src/silc/core/client_ops.c.
4101 * Renamed silc_command_free_payload to silc_command_payload_free.
4102 Affected file lib/silccore/silccommand.h
4104 * Added silcmath.h to include the prototoypes of various routines
4105 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4108 * Changed the following headers to ROBODoc format:
4110 lib/silccore/silcchannel.h
4111 lib/silccore/silccommand.h
4112 lib/silccore/silcid.h
4113 lib/silccore/silcidcache.h
4114 lib/silccore/silcmode.h
4115 lib/silccore/silcnotify.h
4116 lib/silccore/silcpacket.h
4117 lib/silcmath/silcmath.h
4119 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Added checking to the server code not to start the server if
4122 ciphers and stuff are not configured properly. Affected files
4123 silcd/serverconfig.[h] and silcd/server.c.
4125 * Changed the layout of the header files of the public interfaces
4126 in the SILC libraries. The new layout supports ROBODoc
4127 documentation tool (and some others) so that it is easy to create
4128 a library reference manual. All the other headers and source
4129 code must still follow the CodingStyle document. Also source
4130 code must not include these ROBODoc stuffs, only the headers.
4131 Furthermore, all public interface headers must now be named
4132 by using `silc' prefix, example: silcapi.h, silccipher.h.
4133 Some files were renamed due to this. All the other headers
4134 must not be used as public interfaces. I will update the
4135 CodingStyle document later. Changed following headers, so far:
4137 lib/silcclient/silcapi.h
4138 lib/silccore/silcauth.h
4139 lib/silccore/silcprivate.h
4140 lib/silccrypt/silcdh.h
4142 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Removed silc_client_packet_send_flush from the client library
4147 as it is not needed. Affected file lib/silcclient/client.[ch].
4149 * Added printing of message of unresolved authentication method
4150 to the Irssi SILC client. Added it to the module formats.
4151 Removed the same message from the client library.
4153 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Added new distribution feature, DISTLABEL. Every distribution
4156 can define own preprocessor label that can be used in the
4157 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4158 file distributions, acconfig.h.pre and prepare.
4160 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Added Makefile.defines_int to include the actual definitions
4163 for Makefile.defines.in. Tested the new distribution system,
4164 created distributions and tested installation.
4166 * Added AWAY message printing to the Irssi SILC client. Added
4167 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4169 * Added SCONNECT command to call the SILC's CONNECT command.
4170 Cannot use CONNECT directly since Irssi uses that internally.
4171 Affected file irssi/src/silc/core/silc-servers.c.
4173 Added ACTION local command. It is same as ME command but takes
4174 the channel as mandatory argument.
4176 Rewrote some of the Irssi's help files to suite for SILC
4179 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Added Makefile.defines[.in] that should for now on be included
4182 in all Makefile.am file in the source tree. That file includes
4183 all common compilation definitions for SILC source tree.
4185 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Minor changes to the ./prepare script to change the package
4188 name according the distribution name to the configure.in.
4190 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Created new distribution system. Added file `distributions'
4193 that defines all the distributions that can be created out of
4194 the SILC source tree. The ./prepare script now reads that
4195 file to determine how to prepare the distributions. The
4196 first argument to the ./prepare is the name of the distribution
4197 and second is the version of the distribution. If given
4198 without arguments it creates the default (toolkit) distribution
4199 with the default version (defined in ./prepare).
4201 All Makefile.am files that are subject to the distributions
4202 are now named as Makefile.am.pre. These are ./Makefile.am
4203 and lib/Makefile.am. Others may be changed later.
4205 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Added invite list, ban list, some key management and connection
4208 error message printing to module formats in the Irssi SILC client.
4210 * Added new silc_client_set_away_message to set the away message
4211 that is back to the person who sent private message. The
4212 affected file lib/silcclient/silcapi.h and the
4213 lib/silcclient/client_prvmsg.c.
4215 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Fixed the private message sending in the Irssi SILC client,
4218 added local command KEY to the Irssi SILC client.
4220 Added key management and key agreement message formats to the
4221 irssi/src/fe-common/silc/module-formats.[ch].
4223 Added USERS (alias WHO) printing, server/router operator
4224 indication and LIST command printing to the module formats.
4226 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Fixed channel joining notify handling, cumode notify handling
4229 from Irssi SILC client.
4231 * Added SILC specific module-formats to the Irssi SILC client so
4232 that SILC specific message hilighting, colors etc is possible.
4233 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4235 Added channel mode, channel user mode, actions, notices,
4236 whois and whowas printing to the the module-formats.c.
4238 * Fixed a bug in channel deletion in the server. The channel
4239 is not left to the cache even if the channel founder auth mode
4240 is set when there are no users anymore on the channel. Affected
4241 file silcd/server.c.
4243 * The silc_net_localhost now resolves the entire hostname including
4244 the domain name. Affected file lib/silcutil/silcnet.c.
4246 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Changed the ask_passphrase client operation to be ascynchronous.
4249 It has now a completion callback and a context that the
4250 application must call after it has got the passphrase from
4251 the user. Affected files lib/silcclient/silcapi.h,
4252 lib/silcclient/protocol.c, lib/silcclient/command.c and
4255 Added SilcAskPassphrase callback that the application calls
4256 to deliver the passphrase to the library.
4258 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4259 The public key verification and especially a certificate
4260 verification is asynchronous procedure.
4262 Added new SILC_SKE_STATUS_PENDING status to indicate the
4263 request is pending and a callback will be called to finalize
4266 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4267 indicate that remote end did not send its public key (or
4268 certificate), even though we require it. Added check for this
4269 condition in the SKE. This was a security bug, now fixed.
4271 Defined new SilcSKEVerifyCbCompletion callback that is called
4272 when the verification process is completed.
4274 The affected files lib/silcske/silcske_status.h and
4275 lib/silcske/silcske.[ch].
4277 * Changed the verify_public_key client operation to be async
4278 as well. Defined SilcVerifyPublicKey callback that is used to
4279 indicate the success of the public key verification process.
4281 Changed the server and client to use the new async client
4284 * Changed the Irssi SILC client's internal scheduler to be called
4285 twice as many times as it used to be. As a result the client
4286 should be a bit faster now. Affected file is
4287 irssi/src/silc/core/silc-core.c.
4289 * Added support to Irssi SILC client of asynchronous public key
4290 verification and passphrase inquiry. Affected file is
4291 irssi/src/silc/core/silc-core.c.
4293 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Do not say "You have left channel %s" in client library.
4296 Moved it to the application. Affected files are
4297 lib/silcclient/command.c and silc/client_ops.c.
4299 * Fixed silc_client_get_clients. Command context was not
4300 duplicated and was freed memory in the callback. Affected
4301 file lib/silcclient/idlist.c.
4303 * Do not say "you are now talking..." on JOIN command in the
4304 client library. The appliation must handle it.
4306 * Do not say ".. changed topic to" in command reply in the
4307 client libary. The application must handle it.
4309 * Fixed TOPIC command sending in the client library.
4311 * Fixed a memory leak in silc_client_command_free in the file
4312 lib/silcclient/command.c.
4314 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Imported a modified version of Irssi client to the source tree.
4317 The Irssi will be used to create a new client called
4318 Irssi SILC. Imported to irssi/.
4320 Added silc_core_init_finish function to the Irssi. Affected
4321 file irssi/configure.in.
4323 A lot changes in the Makefile.ams around the irssi tree.
4325 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Do not rehash if the new size is same as the old size of the
4328 hash table, in the silc_hash_table_rehash*. The affected file
4329 lib/silcutil/silchashtable.c.
4331 * Replaced hash_table_del_by_context calls from the server
4332 (when channel->user_list and client->channels) to the
4333 hash_table_del as it is sufficient and faster.
4335 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Added silc_hash_table_list, silc_hash_table_get and the
4338 SilcHashTableList structure to provide an alternative way to
4339 traverse the hash table. The affected files are
4340 lib/silcutil/silchashtable.[ch].
4342 * Changed the server's idlist routines to use the hash table
4343 routines to optimize the code.
4345 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Replaced the client entry's `channel' list and channel entry's
4348 `user_list' list to hash tables for optimized lookup. Changed
4349 the code to use the hash table interface around the code.
4350 Affected file lib/silcd/idlist.[ch].
4352 * Added `auto_rehash' boolean argument to the function
4353 silc_hash_table_alloc to indicate whether the hash table should
4354 auto-rehash when it thinks is appropriate time. It will
4355 increase the hash table size if the there is twice as much
4356 entries in the table than the size of the table, and will
4357 decrease the size if there are twice as less entries than
4358 the size of the table.
4360 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4364 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * silc_idcache_purge_by_context deletes the entry now by context
4367 as it is supposed to do. Affected file lib/silccore/idcache.c.
4369 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4370 client is not anymore valid (WHOWAS givens the info) and not
4371 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4373 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Removed the `data' and `data_len' arguments from the ID Cache
4376 interfaces and added `name' argument. ID Cache does not handle
4377 anymore the binary data only a names associated with given ID.
4379 * When hashing a Client ID with silc_hash_id the entire ID is
4380 not hashed anymore, instead only the hash of the Client ID is
4381 hashed. This way we can access the Client ID from the cache
4382 with Client ID but with the hash of the ID (which is a hash of
4383 the nickname) as well without any difference in performance.
4385 Added also silc_idcache_find_by_id_one_ext to do one on one
4386 searching when we have the actual ID. Added also function
4387 silc_hash_client_id_compare. The affected files are
4388 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4390 * When hashing the name associated with a ID it is always done
4391 in lowercase. This way we can access the cache without worrying
4392 about case-sensitivity, even though, for example nicknames are
4395 * Fixed a bug in server with channel message sending. It put
4396 wrong ID type as destination ID. The affected file
4397 silcd/packet_send.c.
4399 * silc_idcache_del_by_context now deletes from all hash tables
4400 by context. Affected file lib/silccore/idcache.c.
4402 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Changed the client library to use the new ID Cache interface.
4405 Changes around the source tree.
4407 * Added silc_hash_table_rehash_ext to rehash with specific
4408 hash function. Affected file lib/silcutil/silchashtable.[ch].
4410 * Added silc_hash_string_compare to compare two strings in the
4411 hash table. Affected file lib/silcutil/silcutil.[ch].
4413 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Added new function silc_idcache_del_by_context into the
4416 lib/silccore/idcache.[ch].
4418 * Changed the server's ID list routines to use the new ID Cache
4419 interface. Changes around the source tree.
4421 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Added silc_hash_table_del[_by_context]_ext functions in to the
4424 lib/silcutil/silchashtable.[ch].
4426 Removed silc_hash_table_find_all* routines and added new
4427 silc_hash_table_find_foreach to replace them.
4429 Added silc_hash_table_replace_ext function as extended
4430 replacing function. Separated the simple hash table interface
4431 from the extended hash table interface in the file
4432 lib/silcutil/silchashtable.h.
4434 * Fixed minor bugs and changed it to use some of the new
4435 hash table functions in lib/silccore/idcache.c
4437 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Added new function silc_hash_table_find_all to return all keys
4440 in the hash table by the specified key. As the hash table is
4441 collision resistant it also makes it possible to have several
4442 duplicate keys in the hash table. This function may be used to
4443 find all of the keys from the hash.
4445 Added user_context arguments to the SilcHashFunction,
4446 SilcHashCompare and SilcHashDestructor to deliver user specified
4449 Added new fuctions silc_hash_table_find[_all]_ext to do
4450 extended lookup with specified hash and compare functions and
4451 specified user contexts.
4453 Added new function silc_hash_table_add_ext to add the key
4454 with specified hash function and user context.
4456 Added new function silc_hash_table_foreach to traverse all
4457 entrys in the hash table. Added SilcHashForeach callback
4460 Added new function silc_hash_table_del_by_context to delete
4461 the entry only if the context associated with the key matches.
4463 Affected files are lib/silcutil/silchashtable.[ch].
4465 * Removed silc_hash_[server/client/channel]_id and added just
4466 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4467 silc_hash_id_compare to compare two ID's using as the hash table
4468 comparison function. Added also silc_hash_data to hash
4469 binary data and silc_hash_data_compare to compare it.
4471 * Removed silc_idlist_find_client_by_hash as it is not needed
4472 anymore. Affected file silcd/idlist.[ch].
4474 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4475 to use internally the SilcHashTable. The new ID Cache is a lot
4476 faster than the old one. Some of the ID Cache interface was also
4477 rewritten and obsolete and stupid functions were removed.
4479 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Added entry_count field to the SilcHashTable to keep the number
4482 of the entries in the table. Implemented the function
4483 silc_hash_table_rehash. Added new function
4484 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4486 Fixed a minor bug in silc_hash_table_free.
4488 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4489 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4490 into the lib/silcutil/silcutil.[ch].
4492 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Implemented a collision resistant hash table into the
4495 lib/silcutil/silchashtable[ch]. See the header and the source
4496 for the SilcHashTable API.
4498 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Merged dotconf version 1.0.2 into lib/dotconf.
4502 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Do not compile anything in lib/silcsim/* if the SIM support
4505 is not enabled. The tree should now compile without problems
4508 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Compiled the SILC under cygwin. Compiled and tested briefly
4511 without problems. More tests needed. The SIMs didn't compile
4514 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4516 * Fixed possible crash in silc_get_username in the
4517 lib/silcutil/silcutil.c.
4519 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Fixed a va_arg in silc/client_ops.c.
4523 * Oops, RC5 routines were named AES and caused some problems
4524 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4526 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Added new SilcIDIP structure into the lib/silccore/id.h and
4529 replaced the old `ip' fields from all SILC ID's to that type.
4530 This is a step towards IPv6 support.
4532 The silc_id_get_len takes now the ID as an extra argument.
4533 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4534 both IPv4 and IPv6 based ID's.
4536 The affected files are lib/silccore/id.[ch] and other files
4537 around the tree using these routines.
4539 * Removed the ID length arguments in server from various
4540 silc_server_send_notify_* routines -> they are not needed
4543 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Fixed memory leak in silc_encode_pem_file in the file
4546 lib/silcutil/silcutil.c.
4548 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Check minor version as well in the SKE. Affected files are
4551 silcd/protocol.c and lib/silcclient/protocol.c.
4553 * Added --identifier option to the server so that an identifier
4554 can be when creating the public key for the server. Affected
4555 file is silcd/silcd.c.
4557 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4558 lib/silccrypt/silcpkcs.c.
4560 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Register default ciphers and stuff when using -C option with
4563 the server. Affected file sildc/silcd.c.
4565 * Put back the servers public key filename format, it is better
4566 than the new one. For now, the client keys are saved with the
4567 new filename format. The affected file silc/client_ops.c.
4569 * Implemented the Cipher API for the rest of the ciphers that
4570 did not implement it or implemented it the wrong way.
4572 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Register default ciphers and stuff when using the -S option
4575 in the client. Affected file silc/silc.c. Same also when
4576 creating new key pair with -C option.
4578 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Fixed the silc_verify_public_key client operation function to
4581 save the public keys differently. The fingerprint is now
4582 used as filename and not the hostname. This way also the
4583 client keys are saved uniquely and not with hostnames. The
4584 affected file is silc/client_ops.c.
4586 * Trimmed the silc_hash_fingerprint function to remove extra
4587 whitespaces from the end of the fingerprint. The affected
4588 file is lib/silccrypt/silchash.c.
4592 * Added silc_cipher_register_default function to register all
4593 default ciphers. It can be used when configuration files
4594 does not exist and the application does not want any specific
4595 ciphers in any specific order.
4597 The SilcDList is now used as silc_cipher_list dynamically
4598 allocated cipher list. Removed the static list all together
4599 and now all ciphers must be allocated to the dynamic list.
4600 The silc_cipher_alloc routine was changed to check only the
4603 All silc_cipher_* routines that used to return int returns
4606 The affected files lib/silccrypt/silccrypt.[ch].
4608 * The same thing was done to silc_hash_* as for silc_cipher_*
4609 routines. Affected files lib/silccrypt/silchash.[ch].
4611 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4612 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4613 Added also silc_pkcs_[un]register[_default] functions.
4614 Removed the data_context from the PKCS API.
4616 * Added silc_hmac_register_default function to register default
4617 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4618 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4619 to unregister all hmacs at once.
4621 * Register the default ciphers, hash functions, PKCSs and HMACs
4622 if client's configuration file does not exist. The affected
4625 * The client did not load the hash functions from the SIM
4626 modules at all. Added support for this. Affected file is
4627 silc/clientconfig.c.
4629 * When decoding public key with silc_pkcs_public_key_decode, check
4630 the supported algorithm only if PKCS are registered. Affected
4631 file lib/silccrypt/silcpkcs.c. The same was done with the
4632 silc_pkcs_private_key_decode.
4634 * Fixed the SILC List routines to keep the list always in order.
4635 It used to change the list's order when traversing the list but
4636 not it preserves the order. Affected file lib/trq/silclist.h.
4638 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Added the client library to use the SilcSocketConnection's
4641 reference counter (by silc_socket_dup) to prevent the bug that
4642 the socket object may be freed underneath async operation.
4644 * The name resolv library checking fixes in the configure.in.pre.
4647 * Created new version of the protocol drafts for future
4648 development. The -03 drafts are the ones that will be changed
4649 in the trunk now and the -02 will remain as they are.
4651 * Send list of CUMODE notifys to the router when announcing
4652 the channel users to the router. Affected file silcd/server.c.
4653 If the router receiving channel founder CUMODE for a channel
4654 that already has channel founder it will send CUMODE notify
4655 to the sender to remove the channel founder rights from the
4656 announced client. Affected file silcd/packet_receive.c.
4658 * The CUMODE notify may now use Server ID as well as the entity
4659 who changes the mode. Updated protocool specs.
4661 * Updated INSTALL and README files.
4663 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * New web pages in the http://silc.pspt.fi. The pages was
4670 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Implemented the [DenyConnectin] config section in the server.
4673 Added silc_server_config_denied_conn to check whether incoming
4674 connection is denied. Affected file silcd/serverconfig.[ch].
4676 * Do not check the ports when checking the incoming configuration
4677 data if the port is 0, meaning any. Affected file is
4678 silcd/serverconfig.c.
4680 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Fixed buffer overflow in silc_string_compare in the file
4683 lib/silcutil/silcutil.c.
4685 * Fixed double free in silc_server_command_leave in the file
4688 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Fixed the version checking in the server. Affected file is
4693 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Fixed the configuration data fetching when accepting new
4696 connections in the server. Affected file silcd/server.c.
4698 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Added `sender_entry' argument to the function
4701 silc_server_packet_relay_to_channel so that we can check
4702 whether some destination actually belongs to the same route
4703 the sender belongs (ie, we must not resend the packet to the
4704 sender). Affected file silcd/packet_send.[ch].
4706 * Added `servername' field to the SilcClientEntry in the server
4707 to hold the name of the server where client is from. Affected
4708 file is silcd/idlist.h.
4710 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Moved the channel message encrypting in the router betwen
4713 router connections from silc_server_channel_message to the
4714 silc_server_packet_relay_to_channel since we want to check
4715 whether we have anybody channel before encrypting anything.
4716 Affected files silcd/packet_[receive/send].c.
4718 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Fixed the [AdminConnection] server config section to support
4721 multiple entries. Affected file silcd/serverconfig.c.
4723 * Added support into the server to check the validity of the
4724 incoming connection before executing any KE or authentication
4727 * The connection configuration is now saved to the KE and
4728 connection auth protocol contexts and not fetched anymore in
4729 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4731 * The local hosts listenning address and port is also resolved
4732 now when starting the server. We want to have the socket object
4733 to include the real address and port for the listener. Added
4734 new function silc_net_check_local_by_sock into the files
4735 lib/silcutil/silcnet.[ch].
4737 * Fixed a broadcast bug in server -> do not broadcast if we
4740 * Fixed a routing bug. Do not route broadcast packets ever.
4741 Broadcast packets must be processed always and not routed since
4742 they may be destined to some other host than yourself and thus
4743 would get routed without no good reason. Affected file is
4746 * Added function silc_server_config_is_primary_route to check
4747 whether primary router connection has been configured (a router
4748 configuration that we are initiating). If there is not, we
4749 will assume that there is only two routers in the SILC network
4750 and we will use the incoming router connection as our primary
4751 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4753 * Changed the order of the broadcasting. Broadcast _after_ the
4754 packet has been processed not before. Affected file is
4757 * Fixed a [ClientConnection] parsing bug. The port was never
4758 parsed correctly thus resulting to port 0. Affected file
4759 silcd/serverconfig.c.
4761 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4762 argument and did not set the broadcast packet flag. Affected
4763 file silcd/packet_send.c. Fixed same bug in the function
4764 silc_server_send_notify as well.
4766 * If we receive NEW_ID packet for our own ID in the server, ignore
4769 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Removed the nickname from the Private Message Payload.
4774 Updated the code and the protocol specs.
4776 * Updated protocol specs for submitting to the IETF.
4778 * Tweaked the Random Number Generator a bit. Affected file
4779 lib/silccrypt/silcrng.c. Exported a new function
4780 silc_rng_[global]_add_noise which can be used to add more
4783 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Do not parse packets with different timeout when protocol
4786 is active -> may cause problem with rekey. Affected file
4789 * When server receives signoff notify it must not create
4790 new channel key if the client is on any channels since the
4791 sender of the signoff notify will create it.
4793 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Added printing of error messages during SKE protocol from the
4796 failure packet sent by server during SKE. Affected file
4799 * Removed the client's failure_callback handling with timeout
4800 and handle it immediately when received.
4802 * The SKE library returned wrong type in SUCCESS and FAILURE
4803 packets. They must be 32 bit MSB not 16 bit MSB.
4805 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Ok, rewrote the logic of the re-key and now it seems to work.
4808 I tested it on high traffic with frequent re-keys without
4809 problems. Added hmac_receive (and renamed hmac to hmac_send)
4810 in SilcClientConnection in lib/silcclient/client.h and
4811 in SilcIDListData in silcd/idlist.h. Also, removed the
4812 SilcPacketParserContext's cipher and hmac fields as they are
4813 not needed anymore and actually caused some problems when
4814 the ciphers and hmac's changed underneath the packet parser.
4816 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4818 * If re-key protocol is active then process the incoming packets
4819 synchronously since we must assure that icoming packets encrypted
4820 with the old key is processed before the new keys is set to
4821 use. This is true other packets than for REKEY packets.
4822 Affected file silcd/server.c. The same was done to client library
4823 as well, affected file lib/silcclient/client.c.
4825 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Fixed bug in client and server to accept the force send if
4828 the packet is send from silc_[server/client]_packet_process
4829 function. Otherwise the packets are never delivered, oops.
4831 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Disable force sending of packets when REKEY protocol is active.
4834 We must assure that no packet is sent directly when rekey is
4835 performed. All packets must be sent through packet queue.
4836 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4837 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4838 function is silc_[server/client]_packet_send_real to check
4841 * Replaced the SIM paths from example config files to
4842 /usr/local/modules. Also, make install creates now
4843 /usr/local/silc/logs directory to hold all the SILC server
4846 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Made the configure.in.pre work on Solaris. Patch by salo.
4850 * Made all ciphers compatible with non-x86 machines. Defined
4851 CBC mode macros into lib/silccrypt/ciphers_def.h.
4853 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Fixed the make install.
4857 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * When MAC computation fails the silc_packet_decrypt returned 0
4860 even though it was supposed to return -1. Fixed this. The
4861 affected file is lib/silccore/silcpacket.c.
4863 * Do not replace the config files in /etc/silc (in make install)
4864 if they already exist. Affected file ./Makefile.am.
4866 * Do not send re-key packets immediately but through packet queue.
4867 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4869 * Changed silc_net_check_host_by_sock to return FALSE if the
4870 IP/DNS could not be resolved. Though, it returns the IP address
4871 now even if it could not resolve it (but returns also FALSE).
4872 Affected file lib/silcutil/silcnet.[ch].
4874 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Added silc_pkcs_decode_identifier to decode the public key's
4877 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4878 Added also silc_pkcs_free_identifier. Added also new context
4879 SilcPublicKeyIdentifier.
4881 * Added -S option to the silc client. It is used to dump the
4882 contents of the specified public key file.
4884 * Changed the PKCS api to return the public key length when
4885 setting the public key.
4887 * Fixed a fatal bug in the public and private key file loading.
4888 Affected file lib/silccrypt/silcpkcs.c.
4890 * Execute the packet parsing for client with zero (0) timeout
4891 if the protocol is active. Affected file silcd/server.c.
4893 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Made the key generation options to the silcd program. Added
4896 -C option, equivalent to client's option.
4898 * Added new [ServerKeys] config section to the server. It
4899 configures the server's public and private key.
4901 * Defined generic Public Key Payload into the protocol
4902 specification to send specific type of public keys and
4905 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4906 public key or certificate.
4908 * Implemented the GETKEY command to the server and to the
4909 client library and on user interface.
4911 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Made preliminary `make install' work.
4915 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Added SilcServerRekey context into silcd/idlist.h.
4919 * Added the PFS support as defined in the specification to the
4920 SKE protocol. Affected files lib/silcske/*.c.
4922 * Added `ske_group' field to the SilcServerRekey context to hold
4923 the number of the SKE group that is used with PFS in re-key.
4924 Affected file silcd/idlist.h.
4926 * Added PFS re-key support to the server. Affected file is
4929 * Added silc_protocol_cancel to cancel execution of the next
4930 state of the protocol. Affected file is
4931 lib/silccore/silcprotocol.[ch].
4933 * Added the re-key support with and without PFS to the client
4934 library. Re-key is performed once in an hour, by default.
4936 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4937 Added silc_client_rekey_callback and silc_client_rekey_final.
4938 Affected files are lib/silcclient/protocol.[ch] and
4939 lib/silcclient/client.[ch].
4941 * Removed the `hmac_key' and `hmac_key_len' fields from the
4942 SilcClientConnection structure; not needed. Affected file is
4943 lib/silcclient/client.h.
4947 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Do not ask whether user wants to use the negotiated private key
4950 for private messages, just use it. Affected file is
4951 silc/local_command.c.
4953 * Added `send_enc_key' and `enc_key_len' fields to the
4954 SilcIDListData structure since they are needed in the re-key
4955 phase. Affected file is silcd/idlist.[ch].
4957 * Implemented the simple re-key protocol into the server.
4958 Affected files silcd/server.c and silcd/protocol.[ch]. The
4959 re-key will be performed once in an hour, by default.
4961 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4962 Added silc_server_rekey, silc_server_rekey_callback and
4963 silc_server_rekey_final.
4965 * Removed Tunneled flag from the protocol. Updated the code
4966 and the specifications.
4968 * Adde `pfs' field to the SilcIDListData to indicate whether
4969 the PFS is to be performed in the re-key. Affected file is
4972 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4975 int64 of at least the xintXX size. If void * is less that 4
4976 bytes uint32 * will be used. Defined bool as boolean.
4978 * Changed _ALL_ unsigned long and unsigned int to uint32,
4979 unsgined short to uint16 in the source tree.
4981 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4982 not handle clients that has entry->data.registered == FALSE.
4983 They are not in the network anymore. Affected file is
4986 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Implemented the sending of the SERVER_SIGNOFF notify in the
4989 server. Affected file is silcd/server.c.
4991 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4992 Added also silc_notify_payload_encode_args into the
4993 lib/silccore/silcnotify.[ch].
4995 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4996 Affected file silcd/packet_receive.c.
4998 * Implemented the SERVER_SIGNOFF notify handling in the client
4999 library. Affected file lib/silcclient/client_notify.c. Also,
5000 implemnted the printing of the SERVER_SIGNOFF info to the
5001 application. Affected file silc/client_ops.c.
5003 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5004 if the deleting was successful. Affected file silcd/idlist.[ch].
5006 * Added support for public key authentication in the connection
5007 authentication protocol in the client library. Affected file
5008 lib/silcclient/protocol.c.
5010 * Changed the server's silc_idlist_get_clients_by_* interface
5011 to support already allocated array so that new entries may be
5012 added to pre-allocated array. Affected file silcd/idlist.[ch].
5013 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5014 and command replies.
5016 * All command reply functions in the server now calls the
5017 pending command callback even if error occured. This way the
5018 error will be delivered to the client as well. Affected files
5019 silcd/command.c and silcd/command_reply.c.
5021 * Fixed INFO command to return local server's info if no server
5022 was provided. Affected file lib/silcclient/command.c.
5024 * Removed RESTART command for good. Updated the code and the
5027 * Rewrote parts of the task system. It is a bit simpler now.
5028 Removed unsued task priorities. The affected files are
5029 lib/silcutil/silctask.[ch].
5031 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Moved the USERS printing from the library to the application.
5034 Affected files lib/silcclient/command.c and silc/client_ops.c.
5036 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Added channel key re-key support. The re-key is perfomed
5041 only by the router and is done once in an hour. Added `rekey'
5042 field to the SilcChannelEntry in the server. Affected files
5043 silcd/server.c and silcd/idlist.h.
5045 * Added silc_task_unregister_by_context into the file
5046 lib/silcutil/silctask.[ch].
5048 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Added SILC_UMODE_GONE mode to indicate when the client is not
5051 present in the SILC network. Added also support to the local
5052 command AWAY that will set this mode. Added support of showing
5053 "xxx is gone" in WHOIS command. The USERS command shows the
5054 gone status as well.
5056 * Fixed setting server and router operator privileges in the
5057 server's UMODE command. Affected file silcd/command.c.
5059 * Merged the SKE KE1 and KE2 payloads into one payload. The
5060 new KE payload is equivalent to the old KE2 payload.
5062 Cleaned up the SKE Start Payload parsing. It now uses the
5063 simple buffer unformatting to do the parsing. A lot faster
5066 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5067 to the SKE that is used to indicate whether both of the SKE
5068 parties should perform authentication. By default only the
5069 responder performs authentication. By setting this flag also
5070 the initiator must do authentication. By default it is unset
5071 since in normal SKE case, client to server connection, only
5072 the responder should do authentication. When doing SKE between
5073 two clients both should perform authentication. Updated the
5074 code and the protocol specs.
5076 * A little fix to IDENTIFY command in the server. Search the
5077 client first by hash not nickname. Affected file is
5080 * Fixed the silc_client_close_connection to support closing
5081 the client to client connections wihtout deleting too much
5082 data. Affected file lib/silcclient/client.c.
5084 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5085 are received if protocol used to be active but is not anymore
5086 the application would crash due to NULL pointer dereference.
5087 Affected files silcd/server.c and lib/silcclient/client.c.
5089 * Added `hash' field to the SilcClientConnection to include
5090 the hash function negotiated in the SKE protocol.
5092 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5093 to set the channel founder authentication data. A client can
5094 claim the founder rights later by providing the authentication
5095 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5096 This way the channel founder can regain the channel founder
5097 privileges even it is left the channel. This works only on
5098 local server and the client must be connected to the same
5099 server to be able to regain the founder rights. Updated the
5100 protocol specs accordingly.
5102 Added support to the CMODE command in the client to set the
5103 founder auth data. Read the README to see how to set it.
5105 Added support to the CUMODE command to claim the founder
5106 rights. Read the README to see how to do it.
5108 Added support for the founder authentication to the Channel
5109 Entry in the server. Affected file silcd/idlist.h.
5111 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5112 server's CMODE command. Affected file silcd/command.c.
5114 * Added the following new functions into lib/silccore/silcauth.[ch]:
5115 silc_auth_get_method and silc_auth_get_data.
5117 * The server now saves the remote hosts public key to the
5118 SilcIDListData pointer. Affected file silcd/protocol.c.
5120 * The normal server now does not remove the channel entry from
5121 the cache if the founder authentication data is set. It used
5122 to remove it if the founder was the last one on the channel on
5123 the server and left the channel. The auth data is saved and
5124 if the channel is re-joined later the old entry is used with
5125 the old auth data. Affected files silcd/command_reply.c and
5128 * Removed the `pkcs' field from the SilcIDListData structure
5129 in the server; it is not used. Affected file silcd/idlist.h.
5131 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Fixed packet processing on slow links. Partial packets were
5134 never re-processed because the incoming data buffer was cleared
5135 by the application. Application must not directly clear the
5136 sock->inbuf, the packet processing routines handle it. Fixed
5137 this in client library and in server.
5139 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Fixed the WHOIS and IDENTIFY send reply function to really
5142 check whether to send list or just one entry. Affected file
5145 * Cleaned up the LEAVE command's channel key distribution. The
5146 affected file silcd/command.c.
5148 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5149 can enforce the channel mode as well. In that case the ID
5150 includes the ID of the server. The code now enforces the
5151 mode change if the router have different mode than the server.
5153 * The notify client operation with CMODE_CHANGE notify can now
5154 return NULL client_entry pointer if the CMODE was not changed
5155 by client. Application must check for this.
5157 * Added <Server ID> argument to INFO command to support server
5158 info fetching by Server ID.
5160 * Added silc_server_announce_get_channel_users to get assembled
5161 packets of channel users of the specified channel. Affected
5162 file silcd/server.[ch].
5164 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5165 was freed underneath the ID Cache.
5167 * Re-announce clients when the server received CHANNEL_CHANGE
5168 notify from the router. Affected file silcd/packet_send.c.
5170 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5173 crashed since it did not handle the fact that there is no cipher
5174 called "3" and didn't check the error condition. Now fixed.
5176 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5177 flag. It can be used to send message requests.
5179 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Implemented the RESTART command in the client.
5183 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5184 notice type messages. Added notice printing to the user
5187 * The channel keys are not re-generated if the channel's mode
5188 is PRIVKEY, ie private key on the channel exists. Affected
5189 files silcd/server.c and silcd/command.c.
5191 * Fixed a little bug in channel message delivery when channel
5192 private keys are set in the server. Affected file is
5193 silcd/packet_send.c.
5195 * Changed the setting on channel->on_channel = TRUE from the
5196 silc_client_save_channel_key to the JOIN command reply. The
5197 key payload is not received if the private channel key is set.
5198 Affected file lib/silcclient/command_reply.c and the
5199 lib/silcclient/client_channel.c.
5201 * When the CMODE_CHANGE notify is sent and the channel private
5202 key mode is removed the channel key must be re-generated in
5203 other cells as well. Added this support for the router in the
5204 silcd/packet_receive.c.
5206 * Added new local command NOTICE to send notice message on
5207 channel. Affected file silc/local_command.[ch].
5209 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Added new local command ME to the client. It is used to send
5212 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5213 some action. Affected file silc/local_command.[ch].
5215 * Changed channel_message and private_message client operations
5216 to deliver the message flags to the application. Added also
5217 the `flags' arguments to the silc_client_send_channel_message
5218 and silc_client_send_private_message functions. Affected file
5221 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Redefined the Private Message Payload to support private message
5224 keys and to support the new private message flags. Updated
5225 the protocol specs. Flags makes it possible to have for example
5226 CTCP style messages.
5228 * Added new type SilcPrivateMessagePayload and defined an API
5229 for it in the lib/silcclient/silcprivate.[ch].
5231 * Tested private message private keys successfully. Tested the
5232 private message key set, unset and list commands with the new
5235 * Redefined the Channel Message Payload to include the channel
5236 message flags (equal with private message flags) to support
5237 for example CTCP style messages.
5239 * Defined some of the message (for channel and private message)
5240 flags. Updated the protocol specs and added the flags to the
5241 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5243 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Added SilcKeyAgreementStatus type to the key agreement routines
5246 to indicate the current status and error if one occured.
5247 The status types are defined in the lib/silcclient/silcapi.h.
5249 * Added new local command KEY that is used to set and unset private
5250 keys for channels, set and unset private keys for private messages
5251 with remote clients and to send key agreement requests and
5252 negotiate the key agreement protocol with remote client. The
5253 key agreement is supported only to negotiate private message keys,
5254 it currently cannot be used to negotiate private keys for channels,
5255 as it is not convenient for that purpose.
5257 * Fixed a minor pending callback setting bug in the function
5258 silc_client_get_client_by_id_resolve, now the function works.
5259 Affected file lib/silcclient/idlist.c.
5261 * Added function silc_net_get_local_port to get local bound
5262 port by socket. Added to lib/silcutil/silcnet.[ch].
5264 * Added `sockets' and `sockets_count' fields to the SilcClient
5265 object. They hold the sockets of the listenning sockets in
5266 the client. Listenning sockets may be for example the key
5267 agreement server. Affected file lib/silcclient/client.[ch].
5268 Added functions the silc_client_add_socket and the
5269 silc_client_del_socket. They are exported to the application
5272 * Added ~./silc/clientkeys to support other client's public keys.
5274 * Renamed verify_server_key client operation to verify_public_key
5275 and added one argument to indicate the type of the connection
5276 (server, client etc.).
5278 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added silc_server_connection_auth_request to handle the
5281 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5282 silcd/packet_receive.[ch].
5284 * Added silc_server_send_connection_auth_request into the
5285 silcd/packet_send.c to send the connection auth request packet.
5287 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5290 * Fixed the public key authentication in responder side in the
5291 server. The `auth_data' pointer includes the SilcPublicKey
5292 not the path to the public key. Affected file silcd/protocol.c.
5294 * Implemented the public key authentication in the initiator side
5295 in the server. Affected file silcd/protocol.c.
5297 * Removed the [RedirectClient] config section from the server
5298 configuration. Is not needed and I don't want to implement it.
5300 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Cleaned up the CMODE command in the server. It now works
5303 correctly and supports all the modes defined in the protocol.
5304 Affected file is silcd/command.c.
5306 * Added `hmac_name' field to the SilcChannelEntry in the server
5307 to hold the default HMAC of the channel. It can be set when
5308 creating the channel (with JOIN command). Affected files
5311 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5312 type to indicate the change of the current cipher and hmac
5313 on the channel. Client can safely ignore the <cipher> argument
5314 (if it chooses to do so) since the CHANNEL_KEY packet will
5315 force the channel key change anyway. The <hmac> argument is
5316 important since the client is responsible of setting the new
5317 HMAC and the hmac key into use.
5319 * Fixed the CMODE command in the client library as well.
5321 * Tested CMODE command in router environment successfully.
5323 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Show the version of the remote client (or server) when connecting
5326 to the server. It is logged to the log file. Affected file
5327 is silcd/protocol.c.
5329 * Fixed the KILLED notify handling in the client library. The
5330 client must be removed from all channels when receiving the
5333 Also, do not remove the client entry when giving the KILL
5334 command but when the KILLED notify is received.
5336 * Removed silc_idlist_find_client_by_nickname from the server.
5337 Not needed anymore. Affected files silcd/idlist.[ch].
5339 * Implemented the CHANNEL_CHANGE notify type handling to the
5340 server. Affected file silcd/server.c.
5344 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added silc_server_send_notify_invite to send the INVITE
5347 notify between routers.
5349 * Implemented the INVITE command correctly to the server.
5351 * Implemented the INVITE notify type handling in the server.
5353 * Implemented the INVITE command to the client library and on the
5356 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Added function silc_server_get_client_resolve to find the
5359 client entry by ID from all ID lists and then resolve it
5360 (using WHOIS) if it cannot be found. Affected file is
5363 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Implemented the BAN command to the client library.
5367 * The JOIN command in the server now checks the invite list
5370 * Changed the silc_command_reply_payload_encode_va and the
5371 silc_command_payload_encode_va to support that if argument is
5372 NULL it ignores and checks the next argument. Affected file
5373 lib/silccore/silccommand.c.
5375 * Added silc_server_send_notify_ban to send the BAN notify
5376 type between routers.
5378 * Chaned the silc_notify_payload_encode to support that if
5379 argument is NULL it ignores and checks the next argument.
5380 Affected file lib/silccore/silcnotify.c.
5382 * Tested ban lists in router environment successfully.
5384 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Implemented BAN command to the server, in silcd/command.[ch].
5388 * Removed the BAN and INVITE_LIST modes from the CMODE command
5391 * Added function silc_string_match to regex match two strings.
5392 Affected files lib/silcutil/silcutil.[ch].
5394 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Redefined parts of the SilcChannelEntry in the server to support
5397 the new ban and invite lists.
5399 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Redefined the INVITE command. The same command can be used to
5402 invite individuals to the channel but also to manage the invite
5403 list of the channel (to add to and remove from the invite list).
5404 Updated the protocol specs.
5406 * Added new command SILC_COMMAND_BAN that can be used to manage
5407 the ban list of the channel. Updated the protocol specs.
5409 * Removed the channel modes: the SILC_CMODE_BAN and the
5410 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5411 in the CMODE command. The equivalent features are now available
5412 using INVITE and BAN commands. Updated the protocol specs.
5414 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5415 in the network about change in the current ban list. The notify
5416 type is not used by the client.
5418 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5419 support the invite lists.
5421 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Added new function silc_string_regexify that converts string
5424 including wildcard characters into regex string that can
5425 be used by the GNU regex library. Added into the file
5426 lib/silcutil/silcutil.[ch].
5428 Added silc_string_regex_combine to combine to regex strings
5429 into one so that they can be used as one regex string by
5430 the GNU regex library. Added into the file
5431 lib/silcutil/silcutil.[ch].
5433 Added silc_string_regex_match to match two strings. It returns
5434 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5436 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Imported GNU regex to the soruce tree into lib/contrib.
5439 Fixed some compiler warning from the regex.c.
5441 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Fixed MOTD command in the server to work in router environment.
5445 * Fixed the MOTD command in the client library to support
5446 the server argument in the command.
5448 * Added `nickname_len' argument to the silc_idlist_add_client
5449 in the server, as the `nickname' argument may be binary data
5452 * Added silc_idlist_get_channels to return all channels from
5455 * Implemented LIST command to the server. Affected file is
5458 * Implemented the LIST command to the client library and on the
5461 * Added [<user count>] argument to the LIST command reply.
5462 With private channels the user count is not shown.
5464 * Updated TODO and README.
5466 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * The client entry's data.registered must be TRUE even with
5469 global client entry on global client list. The data.registered
5470 is used to check whether the client is anymore in the network,
5471 for example with WHOWAS command so it must be valid.
5473 * Fixed the WHOWAS command in the server. It now actually works
5474 in router environment. Added function into silcd/command_reply.c
5475 silc_server_command_reply_whowas_save.
5477 * Added silc_idlist_purge function to the silcd/idlist.c
5478 to periodically purge the ID Cache.
5480 * Fixed INFO command in the server. It works now in router
5481 environment. Added <server name> argument to the INFO command
5482 reply. Updated the protocol specs.
5484 * Fixed minor bug in silc_idcache_purge to not purge if the
5485 expire value is zero.
5487 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5488 they were buggy because of the WHOWAS information.
5490 * Fixed local command MSG to handle the async resolving of
5491 the remote client properly. It used to fail the first MSG.
5492 Affected file silc/local_command.c.
5494 * Added `data_len' field to SilcIDCache context.
5496 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Update TODO. Todo in commands in the server.
5500 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5503 used by routers as broadcast packet to inform other routers
5504 about the changed user mode.
5506 Implemented the notify handling in the server. Affected file is
5507 silcd/packet_receive.c. Added the function
5508 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5510 * Added new generic Channel Payload and deprecated the New Channel
5511 Payload. The New Channel Payload is now the generic Channel
5514 * Added new argument `mode' to the silc_server_send_new_channel
5515 as it is required in the Channel Payload now.
5517 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5518 and created a new and real SilChannelPayload to represent the
5519 new generic Channel Payload. Implemented the encode/decode
5520 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5522 * Added silc_server_get_client_channel_list to return the list
5523 of channels the client has joined for WHOIS command reply.
5524 Affected file silcd/server.[ch].
5526 * Implemented the channel list sending in the WHOIS command reply
5527 in server and in the client.
5529 Implemented the channel list displaying on the user interface
5530 as well. Affected file silc/client_ops.c.
5532 * Added silc_channel_payload_parse_list to parse list of Channel
5533 Payloads. It returns SilcDList list of SilcChannelPayloads.
5534 Client for example can use this function to parse the list of
5535 channels it receives in the WHOIS command reply. The caller
5536 must free the list by calling silc_channel_payload_list_free.
5537 Affected files lib/silccore/silcchannel.[ch].
5539 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Added one new argument <user mode> to the WHOIS command reply
5542 to return the mode of the user in SILC. Updated the protocol
5545 Implemented it to the server and client.
5547 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Fixed the mode printing on the user interface on joining.
5550 Affected file silc/client_ops.c.
5552 * Implemented the UMODE command and user modes in general to the
5553 client library and to the user interface.
5555 * Implemented the UMODE command to the server.
5557 * The server now sends UNKNOWN_COMMAND error status if client sends
5558 unknown command. Affected file silcd/command.c.
5560 * All server commands now handle the command identifier the right
5561 way when sending the command reply to the client. The client can
5562 use to identify the command replies with the identifier.
5564 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added silc_server_get_client_route to resolve the route to
5567 the client indicated by the client ID. Affected file is
5570 * Added silc_server_relay_packet as general function to relay
5571 packet to arbitrary destination. This deprecates functions
5572 like _send_private_message_key, _relay_notify etc. Affected
5573 file is silcd/packet_send.[ch].
5575 Removed silc_server_send_key_agreement,
5576 silc_server_send_private_message_key and
5577 silc_server_packet_relay_notify functions from the file
5578 silcd/packet_send.[ch].
5582 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5583 server. Affected file silcd/packet_receive.[ch].
5585 * Implemented the KILL command to the client. Implemented the
5586 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5587 Affected files lib/silcclient/command[_reply].c and
5588 lib/silcclient/client_notify.c. Implemented the KILL notify
5589 printing in the user inteface.
5591 * Fixed a lot silc_parse_nick memory leaks from the client
5592 library in the file lib/silcclient/command.c.
5594 * Changed the silc_server_send_notify_on_channels's `sender'
5595 argument from SilcSocketConnection to SilcClientEntry to
5596 check the sender as entry and not as connection object and not
5597 to send to the client provided as argument. The affected file
5598 is silcd/packet_send.[ch].
5600 * The notify packets that are destined directly to the client used
5601 to not to be processed by the server. Now changed that and the
5602 server processes all notify packets. After relaying the packet
5603 to the client the notify packet is processed in the server.
5605 * The silc_server_free_client_data now checks whether there is
5606 pending outgoing traffic for the client and purges the data to
5607 the network before removing the client entry.
5609 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5612 an client is killed from the SILC Network. Updated the protocol
5615 Added new function silc_server_send_notify_killed to the
5616 silcd/packet_send.[ch].
5618 * Added function silc_server_packet_relay_notify to relay notify
5619 packets that are destined directly to a client. In this case
5620 the server does not process the notify packets but merely relays
5621 it to the client. Affected file silcd/packet_send.[ch].
5623 Added also silc_server_packet_process_relay_notify to check
5624 whereto relay the notify. Affected file is
5625 silcd/packet_receive.[ch].
5627 * Implemented the KILL command to the server.
5631 * Added the backup schema desgined last fall to the protocol
5632 specs for everyone to see. The specification is in the
5633 *-spec-xx.txt draft and the packet type definitions for the
5634 backup routers is in *-pp-xx.txt draft. Thusly, added also
5635 new packet type SILC_PACKET_CELL_ROUTERS.
5637 * A big security problem in the implementation discovered. The
5638 signoff of an client did not cause new channel key generation
5639 which it of course should've done. The channel keys must be
5640 always re-generated when client leaves (or signoffs) the channel.
5641 The silc_server_remove_from_channels funtion now handles
5642 the channel key re-generation.
5644 * Added `sender' argument to the silc_server_send_notify_on_channels
5645 to not to send the client provided as argument. Affected file
5646 silcd/packet_send.[ch].
5648 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Implemented OPER and SILCOPER commands into the server and
5653 * Added silc_auth_verify and silc_auth_verify_data to verify
5654 the authentication directly from the authentication payload.
5655 It supports verifying both passphrase and public key based
5656 authentication. Affected file lib/silccore/silcauth.[ch].
5658 * Added `hash' field to the SilcIDListData structure. It is the
5659 hash negotiated in the SKE protocol. Affected file is
5662 * Slight redesigning of the SilcAuthPayload handling routines.
5663 Do not send SilcPKCS but SilcPublicKey as argument.
5665 * Implemented the public key authentication support to the
5666 serverconfig. The public key is loaded from the provided path
5667 and saved as authentication data to void * pointer. Thus,
5668 changed the unsigned char *auth_data to void *auth_data;
5670 * Fixed SHUTDOWN command to send the reply before the server
5671 is shutdown. :) Affected file silcd/command.c.
5673 * Fixed fatal bug in CONNECT command. The hostname was invalid
5674 memory and server crashed. Affected file silcd/command.c.
5676 * Fixed fatal bug in CLOSE command. The server_entry became
5677 invalid but was referenced later in the command. Affected file
5680 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Fixed fatal bug in failure packet handling. Server ignored
5683 the failure and thus crashed when it came.
5687 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5690 that the command may be executed only once in (about) 2 seconds.
5691 The old SILC_CF_LAG flag is same but allows command bursts up
5692 to five before limiting.
5694 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5695 server code. Various commands now includes the CF_LAG_STRICT
5696 flag to disallow any kind of miss-use of the command.
5698 * Fixed the silc_buffer_unformat to not to allocate any data
5699 if the length of the data is zero. It used to allocate the
5700 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5702 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Changed the format of AdminConnection configuration section
5705 in the server. Added username of the admin to the format.
5706 Affected files silcd/serverconfig.[ch].
5708 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5709 to return admin configuration data by host, username and/or
5712 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Implemented WHOWAS command to the server. Added the functions:
5716 silc_server_command_whowas_parse,
5717 silc_server_command_whowas_send_reply,
5718 silc_server_command_whowas_from_client and
5719 silc_server_command_whowas_from_server
5721 * Added <Client ID> argument to the WHOWAS command reply. Updated
5722 the protocol specs accordingly.
5724 * Implemented WHOWAS command and command_reply to the client
5727 Implemented the WHOWAS printing on the user interface.
5729 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Added new argument to the WHOWAS command reply, the real name.
5732 It is an optional argument. Updated the protocol specs.
5734 * Added SilcIDCacheDestructor callback that is registered when
5735 the SilcIDCache is allocated. The callback is called when
5736 an cache entry in the ID Cache expires, or is purged from the
5737 cache. Added into lib/silccore/idcache.[ch].
5739 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5740 to destruct the client entries when the cache entry expires.
5741 Other ID Cache's in server and in the client library ignores
5744 * If the ID Cache entry's `expire' field is zero then the entry
5745 never expires. Added boolean `expire' argument to the
5746 silc_idcache_add function in the lib/silccore/idcache.[ch].
5747 If it is TRUE the default expiry value is used.
5749 * Added silc_server_free_client_data_timeout that is registered
5750 when client disconnects. By default for 5 minutes we preserve
5751 the client entry for history - for WHOWAS command.
5753 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Added support to the server to enforce that commands are not
5756 executed more than once in 2 seconds. If server receives
5757 commands from client more frequently, timeout is registered
5758 to process the commands. Affected file silcd/command.c.
5759 Added new function silc_server_command_process_timeout.
5761 * Changed NICK_NOTIFY handling in client library to check that
5762 if the client's nickname was changed, so there is no need to
5763 resolve anything from the server.
5765 * Removed error printing from the WHOIS and IDENTIFY commands.
5766 If error occurs then it is ignored silently in the client library.
5767 The application, however, may map the received error to
5768 human readable error string. The application currently maps
5769 the NO_SUCH_NICKNAME error to string.
5771 * Made the command status message public to the application. Moved
5772 them from lib/silcclient/command_reply.c to
5773 lib/silcclient/command_reply.h. The application can map the
5774 received command status to the string with the
5775 silc_client_command_status_message function.
5777 * Added check to the server to check that client's ID is same
5778 as the Source ID in the packet the client sent. They must
5781 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Added dist-bzip hook to the Makefile.am to make bzip2
5784 compressed distributions.
5786 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Server now enforces the maximum length for the nickname and
5789 the channel as protocol specification dictates. 128 bytes for
5790 nickname and 256 bytes for channel name.
5792 * Moved the WHOIS printing to the application. The client libary
5793 does not print out the WHOIS information anymore, the application
5794 must do it. Renamed silc_client_command_reply_whois_print to
5795 the silc_client_command_reply_whois_save.
5797 The client's idle time is also sent to the application now, and
5798 the idle is shown on screen.
5800 * Added silc_client_command_reply_identify_save to save the
5801 received IDENTIFY entries.
5803 * Do not check for channel private keys in message sending and
5804 reception if the channel does not have the PRIVKEY mode set.
5805 Affected file lib/silclient/client_channel.c.
5807 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5810 just surfaced after chaning the JOIN procedure.
5812 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Added silc_client_get_clients_by_list to get client entries
5815 from Client ID list, that is returned for example by JOIN
5816 and USERS command replies. The application should use this
5817 function for example when JOIN command reply is received to
5818 resolve the clients already on the channel (library does not
5819 do that anymore as USERS command reply is not used in the JOIN
5820 procedure anymore). Affected files lib/silcclient/silcapi.h and
5821 lib/silcclient/idlist.c.
5823 * JOIN command reply and USERS command reply returns now SilcBuffer
5824 pointers instead of unsigned char pointers when returning
5825 the client list and mode list.
5827 * Added <Client ID> argument to the JOIN command reply, mainly
5828 for the server to identify for which client the command was
5829 originally sent. Updated protocol specs accordingly.
5831 * Added SilcDlist private_key pointer to the SilcChannelEntry
5832 in the client to support the channel private keys. Affected
5833 file is lib/silcclient/idlist.h.
5835 * Added SilcChannelPrivateKey argument to the function
5836 silc_client_send_channel_message so that application can choose
5837 to use specific private ke if it wants to. If it is not provided,
5838 the normal channel key is used, unless private keys are set.
5839 In this case the first (key that was added first) is used
5840 as the encryption key.
5842 * Implemented the support for channel private key handling.
5843 Implemented the following functions:
5845 silc_client_add_channel_private_key,
5846 silc_client_del_channel_private_keys,
5847 silc_client_del_channel_private_key,
5848 silc_client_list_channel_private_keys and
5849 silc_client_free_channel_private_keys
5851 Affected file lib/silcclient/client_channel.c.
5853 * Added the support for the private keys in the channel message
5854 sending and encryption and in the message reception and
5855 decryption. Affected funtions are
5856 silc_client_send_channel_message and silc_client_channel_message.
5858 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Added SKE's key verify callback to the client library's
5861 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5863 * Removed the statement that server (or router) must send USERS
5864 command reply when joining to the channel so that the client
5865 knows who are on the channel. Instead, the client list and
5866 client's mode list is now sent in the JOIN command reply to the
5867 client who joined channel. This is better solution.
5869 * Added function silc_server_get_users_on_channel and function
5870 silc_server_save_users_on_channel to the silcd/server.[ch].
5872 * Removed function silc_server_command_send_users from the
5875 * Do not show topic on the client library anymore. The topic is
5876 sent in the command reply notify to the application and the
5877 application must show the topic now.
5879 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Added client searching by nickname hash into the IDENTIFY and
5882 WHOIS commands in the server as they were clearly missing from
5883 them. Affected file is silcd/command.c.
5885 * Fixed a bug in private message receiving in the client library.
5886 The remote ID was freed and it wasn't supposed, now it is
5889 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Minor fix to the channel payload; allocate the data area, as it
5892 needs to be of specific length.
5894 * If the key agreement port is zero then the operating
5895 system will define the bound port. Affected files are
5896 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5898 * Added new function silc_channel_payload_decrypt into the file
5899 lib/silccore/silcchannel.[ch].
5901 * Moved the channel message etc, check from silc_packet_decrypt
5902 to applications. The library calls now a generic
5903 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5904 when the packet is either normal or special. This was done to
5905 allow more wide range of checking that was not allowed when
5906 the code was in library. Now applications can do virtually any
5907 checks to the packet and return to the library the decision how
5908 the packet should be processed. Affected files are
5909 lib/silccore/silcpacket.[ch].
5911 Added silc_server_packet_decrypt_check to the server and
5912 silc_client_packet_decrypt_check to the client library.
5914 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5915 to send with specified source and destination information.
5917 * Channel message delivery between routers was broken after the
5918 channel key distribution was fixed earlier. The channel key
5919 was used be to distributed to other routers as well which is not
5920 allowed by the protocol. Now this is fixed and channel keys
5921 really are cell specific and the channel message delivery between
5922 routers comply with the protocol specification.
5924 * Fixed various commands in server to check also the global list
5925 for the channel entry and not just the local list. The affected
5926 file silcd/command.c.
5928 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added assert()s to buffer formatting and unformatting routines
5931 to assert (if --enable-debug) when error occurs. Affected
5932 file: lib/silcutil/silcbuffmt.c.
5934 * Changed to auto-reconnect to check whether the remote host is
5935 router and register the re-connect timeout if it is. It used
5936 to check that whether we are normal server, but router must do
5937 auto-reconnect with another router as well. Affected file
5940 * Removed the [<key len>] option from CMODE command as the cipher
5941 name decides the key length, nowadays. See the defined ciphers
5942 from the protocol specification.
5944 * Added [<hmac>] option to the CMODE command to define the HMAC
5945 for the channel. Added SILC_CMODE_HMAC channel mode.
5947 * Added [<hmac>] option for the JOIN command so that user can
5948 select which HMAC is used to compute the MACs of the channel
5951 * Added Hmac field to the Channel Message Payload. The integrity
5952 of plaintext channel messages are now protected by computing
5953 MAC of the message and attaching the MAC to the payload. The
5954 MAC is encrypted. Now, it is clear that this causes some
5955 overhead to the size of the packet but rationale for this is that
5956 now the receiver can verify whether the channel message decrypted
5957 correctly and also when private keys are set for the channel the
5958 receiver can decrypt the packet with several keys and check from
5959 the MAC which key decrypted the message correctly.
5961 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5962 lib/silccrypt/silccipher.[ch].
5964 * Added silc_hash_len to return the digest length into the
5965 lib/silcrypt/silchash.[ch].
5967 * Rewrote parts of Silc Channel Payload interface in the
5968 lib/silccore/silcchannel.[ch]. The encode function now also
5969 encrypts the packet and parse function decrypts it.
5971 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Fixed a minor formatting bug in the SKE's key material processing.
5974 It actually might have processed the keys wrong way resulting
5977 * Redefined the mandatory HMAC algorithms and added new algorithms.
5978 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5979 and hmac-md5 truncated to 96 bits. The mandatory is now
5980 hmac-sha1-96. Rest are optional (including the one that used
5981 to be mandatory). Rationale for this is that the truncated HMAC
5982 length is sufficient from security point of view and can actually
5983 make the attack against the HMAC harder. Also, the truncated
5984 HMAC causes less overhead to the packets. See the RFC2104 for
5987 * Added new [hmac] configuration section. The SKE used to use
5988 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5989 is of course wrong. The official names that must be proposed in
5990 the SKE are the ones defined in the protocol specification
5991 (hmac-sha1-96 for example). The user can configure any hmac
5992 using any hash function configured in the [hash] section. At
5993 least, the mandatory must be configured.
5995 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5997 * Added HMAC list to the SKE proposal list. It has now both
5998 hash algorithm list and HMAC list. This makes the protocol
5999 incompatible with previous versions. The SKE now seems to work
6000 the way it is supposed to work, for the first time actually.
6002 * Defined plain Hash algorithms to the protocol specification.
6005 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Implemented support for key agreement packets into the server.
6008 Added functions silc_server_key_agreement and
6009 silc_server_send_key_agreement. Other than these functions,
6010 server has nothing to do with this packet.
6012 * Added support for private message key packets into the server.
6013 Added functions silc_server_private_message_key and
6014 silc_server_send_private_message_key.
6018 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6019 called in the protocol's final callback instead in the END
6020 protocol state. This makes a little more sense and in the same
6021 time in client we can use the same protocol routines for normal
6022 key exchange and to key agreement packet handling as well.
6024 * Added to both client's and server's KE protocol context the
6025 SilcSKEKeyMaterial pointer to save the key material. We will
6026 bring the key material to the protocol's final callback by doing
6027 this. The final callback must free the key material.
6029 * Added SKE's packet_send callback into client's KE protocol
6030 context so that the caller can choose what packet sending function
6031 is used. This way we can use different packet sending when
6032 doing normal SKE when doing key agreement packet handling (in
6033 the key agreement packet handling we do not want to encrypt
6036 * Implemented the responder side of the key agreement routines
6037 in the client. The client can now bind to specified port and
6038 accept incoming key negotiation. The key material is passed
6039 to the application after the protocol is over.
6041 * Implemented the processing of incoming Key Agreement packet
6042 in the client. Added function silc_client_key_agreement to
6045 * Implemented the intiator side of the key agreement routines
6046 in the client. The client can now initiate key agreement with
6047 another remote client. The key material is passed to the
6048 application after the protocol is over.
6050 * Created client_keyagr.c to include all the key agreement
6053 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6054 SILC_TASK_CALLBACK except that it is not static.
6056 * Created client_notify.c and moved the Notify packet handling
6057 from the client.[ch] into that file.
6059 * Created client_prvmsg.c and moved all private message and
6060 private message key routines from the client.[ch] into that file.
6062 * Create client_channel.c and moved all channel message and
6063 channel private key routines from the client.[ch] into that file.
6065 * Changed silc_client_get_client_by_id_resolve to resolve with
6066 WHOIS command instead of IDENTIFY command, in the file
6067 lib/silclient/idlist.c.
6069 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Implemented the SKE's responder side to the Client library.
6073 * When FAILURE is received to the protocol do not trust it
6074 blindly. Register a timeout to wait whether the remote closes
6075 the connection as it should do it, only after that process the
6076 actual failure. This was changed to both client and server.
6078 * Added client_internal.h to include some of the structures
6079 there instead of client.h in lib/silcclient/.
6081 * Added function silc_task_unregister_by_callback to unregister
6082 timeouts by the callback function.
6084 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Some "Incomplete WHOIS info" errors has been appearing on the
6087 log files. Took away the entry->userinfo check from WHOIS
6088 reply sending. The entry->userinfo is now " " if client did not
6089 provide one. I thought this was fixed earlier but something
6090 is wrong still. Let's see if the error still appears.
6092 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Fixed a minor bug in the login when the channel key is
6095 re-generated in the server. It used to generate the key in
6096 wrong order and thus caused problems in the channel traffic.
6098 * Fixed a minor bug in channel key distsribution after
6099 KICK command. The key was not sent to the router even though
6102 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Added silc_ske_process_key_material_data as generic routine
6105 to process any key material as the SILC protocol dictates. The
6106 function is used by the actual SKE library but can be used by
6107 applications as well. This relates to the private message keys
6108 and the channel private keys since they must be processed the
6109 same way the normal SILC session keys. The protocol dictates
6110 this. Affected files: lib/silcske/silcske.[ch].
6112 Added also silc_ske_free_key_material to free the
6113 SilcSKEKeyMaterial structure.
6115 * Defined silc_cipher_set_key function to set the key for
6116 cipher without using the object's method function. The affected
6117 files: lib/silccrypt/silccipher.[ch].
6119 * Implemented silc silc_client_add_private_message_key,
6120 silc_client_add_private_message_key_ske,
6121 silc_client_del_private_message_key,
6122 silc_client_list_private_message_keys and
6123 silc_client_free_private_message_keys functions in the
6126 Added functions silc_client_send_private_message_key to send
6127 the Private Message Key payload and silc_client_private_message_key
6128 to handle incoming Private Message Key payload.
6130 * Added Cipher field to the Private Message Key payload to set
6131 the cipher to be used. If ignored, the default cipher defined
6132 in the SILC protocol (aes-256-cbc) is used.
6134 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Removed lib/silcclient/ops.h file.
6138 Redefined parts of the SILC Client Library API. Created new
6139 file silcapi.h that deprecates the ops.h file and defines the
6140 published Client Library API. Defined also private message key
6141 API and channel private key API into the file.
6143 This is the file that the application must include from the
6144 SILC Client Library. Other files need not be included by
6145 the application anymore.
6147 * Added new key_agreement client operation callback and also
6148 defined the Key Agreement library API for the application.
6150 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6153 is used by clients to request key negotiation between another
6154 client in the SILC network. If the negotiation is started it
6155 is performed using the SKE protocol. The result of the
6156 negotiation, the secret key material, can be used for example
6157 as private message key.
6159 Implemented the Key Agreement payload into the files
6160 lib/silccore/silauth.[ch].
6162 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Redefined ciphers for the SILC protocol. Added some new ciphers
6165 and defined the key lengths for the algorithms. Changed the
6166 code accordingly. The default key length is now 256 bits.
6168 * Fixed SKE key distribution function silc_ske_process_key_material
6169 when the key length is more than 128 bits. The default key
6170 length in SILC is now 256 bits.
6172 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6173 to indicate unsupported algorithm.
6175 * Renamed rijndael.c to aes.c and all functions as well.
6177 * Fixed a long standing channel key setting bug in client library.
6178 Weird that it has never surfaced before.
6180 * Fixed bug in channel deletion. If the entire channel is removed
6181 then it must also delete the references of the channel entry
6182 from the client's channel list as the client's channel entry and
6183 the channel's client entry share same memory.
6185 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Implemented CONNECT and SHUTDOWN commands in the client.
6189 * Implemented CLOSE command to the client.
6191 * Added the function silc_idlist_find_server_by_name into the
6192 files silcd/idlist.[ch].
6194 Added the function silc_idlist_find_server_by_conn into the
6195 files silcd/idlist.[ch].
6197 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * DIE command was renamed to SHUTDOWN. Updated the both code
6202 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6203 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6205 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6208 * Added function silc_server_create_connection function to create
6209 connection to remote router. My server implementation actually
6210 does not allow router to connect to normal server (it expects
6211 that normal server always initiates the connection to the router)
6212 so the CONNECT command is only good for connecting to another
6215 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6218 or some other client was kicked from the channel.
6220 Implemented the handling of the notify type to both client
6223 Implemented silc_server_send_notify_kicked to send the KICKED
6224 notify. It is used to send it to the server's primary router.
6226 * Implemented the KICK command into server and client.
6228 * Added `query' argument to the silc_idlist_get_client function
6229 to indicate whether to query the client from server or not if
6232 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6233 to indicate that the client is not channel founder.
6237 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Removed the rng context from SilcPacketContext structure and
6240 changed that the packet routine uses the Global RNG API.
6242 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Added support for quit message that client can "leave" on the
6245 channel when it quits the SILC. It is ditributed inside the
6246 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6248 Added silc_server_free_client_data that will take the
6249 signoff message as argument.
6251 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6253 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Updated parts of the protocol specification to keep it up
6258 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6261 payloads in one packet.
6263 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6264 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6265 use now the new List flag.
6267 * Also deprecated the following packet types: REPLACE_ID,
6268 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6270 * Added list support for Notify packet in server.
6272 * Added silc_server_send_notify_channel_change to send the
6273 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6274 the silc_server_send_replace_id.
6276 * Added silc_server_send_notify_nick_change to send the
6277 NICK_CHANGE notify type. Deprecates the function
6278 silc_server_send_replace_id.
6280 * Added silc_server_send_notify_join to send the JOIN notify type.
6281 Deprecates the function silc_server_send_new_channel_user.
6283 * Added silc_server_send_notify_leave to send LEAVE notify type.
6284 Deprecates the function silc_server_send_remove_channel_user.
6286 * Added silc_server_send_notify_cmode and
6287 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6288 types. Deprecates the silc_server_send_set_mode function.
6290 * Added SERVER_SIGNOFF notify type to indicate that server has
6291 quit. This means that all clients on the channel from that
6292 server will drop. This can be also used when netsplit happens.
6294 Deprecated REMOVE_ID packet type since it is not needed anymore
6297 Added silc_server_send_notify_server_signoff to send the
6298 SERVER_SIGNOFF notify type. Deprecates the function
6299 silc_server_send_remove_id.
6301 Added also silc_server_send_notify_signoff to send the
6302 SIGNOFF notify type.
6304 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6305 SILC protocol from this day on. Changed the protocol
6306 specification as well.
6308 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6309 notify type. It is used between routers to notify about
6310 topic changes on a channel.
6312 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6315 * Partly updated the protocol specification to comply with the
6316 changes now made. It is still though a bit outdated.
6318 * The JOIN notify type now takes one extra argument <Channel ID>.
6319 The packet used to be destined to the channel but now the
6320 JOIN type may be sent as list thus it is impossible to
6321 destine it to any specific channel. By adding this argument
6322 it is again possible.
6324 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Added CREDITS file. The CHANGES and CREDITS file will appear
6327 in the distribution as well.
6329 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6332 types in the server's silcd/packet_receive.c.
6334 * Implemented CMODE and CUMODE to work in router environment.
6336 * Fixed minor encoding and decoding buglet from the
6337 lib/silccore/silcmode.c.
6339 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6342 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6344 * Changed all SilcConfigServer* and silc_config_server* to
6345 SilcServerConfig* and silc_server_config*, respectively.
6348 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Associated the ID (client or server ID) to the Authentication
6351 Payload to avoid any possibility of forging. Updated the
6352 protocol specification and the code accordingly.
6354 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * The RSA key length is now save to the RsaKey context in the
6357 key generation process in lib/silccrypt/rsa.c. The key length
6358 is now used to figure out the maximum size of the block allowed
6359 to be encrypted/signed.
6361 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6362 is equivalent to the silc_mp_mp2bin but does not allocate any
6365 * Changed silc_mp_mp2bin API to take length argument. If it is
6366 non-zero then the buffer is allocated that large. If zero, then
6367 the size is approximated using silc_mp_sizeinbase, which however
6370 * Created Global RNG API which is global RNG that application can
6371 initialize. After initializing, any routine anywhere in the
6372 code (including library) can use RNG without allocating a new
6373 RNG object. This was done to allow this sort of use of the
6374 RNG in code that has no chance to allocate RNG object. All
6375 applications currently allocate this and many routines in the
6376 library use this. Affected file lib/silccrypt/silcrng.[ch].
6378 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6379 it to use the Global RNG API.
6381 * Defined Authentication Payload into protocol specification that
6382 is used during SILC session to authenticate entities. It is
6383 used for example by client to authenticate itself to the server
6384 to obtain server operator privileges.
6386 Implemented this payload into the lib/silccore/silcauth.[ch].
6387 Implemented also routines for public key based authentication
6388 as the new protocol specification dictates.
6390 Moved definitions of different authentication methods from
6391 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6393 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6394 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6395 silc_pkcs_verify_with_hash functions into the file
6396 lib/silccrypt/silcpkcs.[ch].
6398 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * The client entry's userinfo pointer must be always valid.
6401 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6402 will fail since it requires the userinfo. Now, the userinfo
6403 is allocated as "" if actual userinfo does not exist. Actually,
6404 it must exist and it is totally Ok to drop client connections
6405 that does not announce the userinfo. However, we will make
6406 this workaround for now.
6408 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6409 to return the remote port by socket.
6411 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6414 SILC_SERVER_PENDING_EXEC and added an new macro
6415 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6416 data or when error occurs while processing the pending command.
6418 Added new argument `destructor' into silc_server_command_pending
6419 and to the SilcServerCommandPending object. This destructor is
6420 now called after calling the pending callback or if error occurs
6421 immediately. If error occurs the actual pending callback won't
6422 be called at all - only the destructor. The destructor may be
6423 NULL if destructor is not needed.
6425 All this applies for client library code as well. Similar
6426 changes were made there as well for the pending commands.
6428 In the client, the application must now allocate the
6429 SilcClientCommandContext with the silc_client_command_alloc
6432 * Added reference counter to the SilcServerCommandContext. Added
6433 function silc_server_command_alloc and silc_server_command_dup
6436 Same type of functions added to the client library for the same
6439 * Removed the cmd_ident from IDListData away since it is now
6440 global for all connections. It is the command identifier used
6441 in command sending and with pending commands. The affected file
6444 * Added reference counter to the SilcSocketConnection objecet to
6445 indicate the usage count of the object. The object won't be
6446 freed untill the reference counter hits zero. Currently only
6447 server uses this, and client ignores it. The client must be
6448 set to use this too later. The affected files are
6449 lib/silccore/silcsockconn.[ch]. Added also the function
6450 silc_socket_dup to increase the reference counter.
6452 This was mainly added because it is possible that the socket
6453 is removed underneath of pending command or other async
6454 operation. Now it won't be free'd and proper DISCONNECTING
6455 flags, etc. can be set to avoid sending data to connection that
6456 is not valid anymore.
6458 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6459 the connection. After that it sets SILC_SET_DISCONNECTED.
6460 It is, however, possible that the socket data is not still freed.
6461 The silc_server_packet_process now checks that data is not
6462 read or written to connection that is DISCONNECTED. The socket
6463 get's freed when the reference counter hits zero.
6465 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Changed the client operation API: channel_message operation's
6468 `sender' is now the client entry of the sender, not the nickname
6469 and the `channel' is the channel entry, not the channel name.
6471 In the private_message operation the `sender' is now also the
6472 client entry of the sender not the nickname.
6474 Affected file is lib/silcclient/ops.h and all applications
6475 using the client operations.
6477 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * Moved the calling of ops->connect() from connect_to_server_final
6480 into receive_new_id functin since that is the point when the
6481 client is actually allowed to send traffic to network. The
6482 affected file is lib/silcclient/client.c.
6484 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6487 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6488 (if needs broadcasting) instead of broadcasting the packets one
6489 by one which would make a burst in the network traffic.
6491 * Added `broadcast' argument to the functions in silcd/server.[ch]
6492 silc_server_create_new_channel[_with_id] to indicate whether
6493 to send New Channel packet to primary router.
6495 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Added new function into the silcd/server.[ch] files:
6498 silc_server_create_new_channel_with_id to create new channel with
6499 already existing Channel ID.
6501 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6502 lib/silccore/silcpacket.h. This packet is used t send list of
6503 Set Mode payloads inside one packet. Server uses this to set
6504 the modes for the channels and clients on those channels, that it
6505 announced to the router when it connected to it. The protocol
6506 specification has been updated accordingly.
6508 * The silc_server_new_channel did not handle the packet coming
6509 from normal server as it normally does not send that. However,
6510 when it announces its channels it does send it. Implemented
6511 the support for that.
6513 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6514 into the file lib/silccore/id.h.
6516 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Fixed memory leaks in the functions silc_idlist_del_client,
6519 silc_idlist_del_channel and silc_idlist_del_server in the file
6520 silcd/idlist.c. All of those leaked like a sieve.
6522 * Fixed some small memory leaks in the client's function
6523 silc_client_notify_by_server.
6525 * Added functions into silcd/server.c: silc_server_announce_clients,
6526 silc_server_announce_channels and silc_server_announce_server.
6527 These functions are used by normal and router server to announce
6528 to its primary router about clients, channels and servers (when
6529 router) that we own. This is done after we've connected to the
6532 These functions effectively implements the following packet types:
6533 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6534 and SILC_PACKET_NEW_ID_LIST.
6536 * Added new functions into the silcd/packet_receive.[ch]:
6537 silc_server_new_id_list, silc_server_new_channel_list and
6538 silc_server_new_channel_user_list to handle the incoming
6539 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6541 * Added support of changing Channel ID in the function
6542 silc_server_replace_id. If the server that announces a channel
6543 to the router already exists in the router (with same name but
6544 with different Channel ID), router is responsible to send
6545 Replace ID packet to the server and force the server to change
6546 the Channel ID to the one router has.
6548 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6549 client that the Channel ID has been changed by the router. The
6550 normal server sends this to the client. Client must start using
6551 the new Channel ID as the channel's ID.
6553 Implemented handling of this new type into lib/silcclient/client.c
6554 into the function silc_client_notify_by_server.
6556 * Added new function silc_idlist_replace_channel_id into the files
6557 silcd/idlist.[ch] to replace the Channel ID.
6559 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Call silc_server_command_identify_check always when processing
6562 the IDENTIFY command in silcd/command.c
6564 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6567 send keepalive packets. The packet can be sent by clients,
6568 servers and routers.
6570 Added function silc_socket_set_heartbeat into the file
6571 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6572 If not set, the heartbeat is not performed. The actual
6573 heartbeat is implemented in the low level socket connection
6574 library. However, application is responsible of actually
6577 Added silc_server_send_heartbeat to send the actual heartbeat
6578 packet into silcd/packet_send.[ch]. Server now performs
6579 keepalive with all connections.
6581 * Added silc_task_get_first function into lib/silcutil/silctask.c
6582 to return the timeout task with shortest timeout. There was a bug
6583 in task unregistration that caused problems. TODO has been
6584 updated to include that task system must be rewritten.
6586 * The client library will now resolve the client information when
6587 receiving JOIN notify from server for client that we know but
6588 have incomplete information.
6590 * Rewrote parts of silc_server_remove_from_channels and
6591 silc_server_remove_from_one_channel as they did not remove the
6592 channel in some circumstances even though they should've.
6594 * Encryption problem encountered in server:
6596 The LEAVE command used to send the Channel Key packet to the
6597 router immediately after generating it. However, the code
6598 had earlier sent Remove Channel user packet but not immediately,
6599 ie. it was put to queue. The order of packets in the router
6600 was that Channel Key packet was first and Remove Channel User
6601 packet was second, even though they were encrypted in the
6602 reverse order. For this reason, MAC check failed. Now, this
6603 is fixed by not sending the Channel Key packet immediately but
6604 putting it to queue. However, this is more fundamental problem:
6605 packets that are in queue should actually not be encrypted
6606 because packets that are sent immediately gets encrypted
6607 actually with wrong IV (and thus MAC check fails). So, packets
6608 that are in queue should be encrypted when they are sent to
6609 the wire and not when they put to the queue.
6611 However, the problem is that the current system has not been
6612 designed to work that way. Instead, the packet is encrypted
6613 as soon as possible and left to the queue. The queue is then
6614 just purged into wire. There won't be any fixes for this
6615 any time soon. So, the current semantic for packet sending
6618 o If you send packet to remote host and do not force the send
6619 (the packet will be in queue) then all subsequent packets to the
6620 same remote host must also be put to the queue. Only after the
6621 queue has been purged is it safe again to force the packet
6624 o If you send all packets immediately then it safe to send
6625 any of subsequent packets through the queue, however, after
6626 the first packet is put to queue then any subsequent packets
6627 must also be put to the queue.
6629 Follow these rules and everything works fine.
6631 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Added new function silc_server_remove_clients_by_server to
6634 remove all client entries from ID list when the server connection
6635 is lost. In this case it is also important to invalidate all
6636 client entires as they hold the invalid server entry. This
6637 fixes fatal bug when server has lost connection and will reconnect
6640 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Made some sanity checks to silc_server_daemonise like to check
6643 whether the requested user and group actually exists.
6645 * Added sanity check to SKE's silc_ske_responder_finish to check
6646 that the public and private key actually is valid.
6648 * Invalidate the client's nickname when receiving Replace ID
6649 packet and the Client ID is being replaced. This means that the
6650 server will query the nickname if someone needs it (client)
6653 * Sort the ID Cache in client library when the ID Cache data
6654 has changed (needs sorting).
6656 * Do not allow for SILC client to create several connections to
6657 several servers. The client does not support windows right now
6658 and generating multiple connections causes weird behaviour.
6660 Irssi-silc client does support windows and can handle several
6661 connections without problems, see: www.irssi.org and SILC plugin.
6663 * Fixed some places where client was added to the IDList. The
6664 rule of thumb is following (in order to get everything right):
6665 If the client is directly connected local client then the
6666 `connection' argument must be set and `router' argument must be
6667 NULL to silc_idlist_add_client function. If the client is not
6668 directly connected client then the `router' argument must
6669 bet set and the `connection' argument must be NULL to the
6670 silc_idlist_add_client function.
6672 * The funtion silc_server_packet_send_local_channel actually did
6673 not check whether the client was locally connected or not. It
6674 does that now. Fixed a bug related to LEAVE command.
6676 * Fixed Remove Channel User payload parsing bug in server's
6677 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6679 * The server's silc_server_save_channel_key now checks also the
6680 global ID list for the channel as it might not be in the local
6681 list. Fixed a bug related to LEAVE command.
6683 * Is this the end of the [<unknown>] buglet that has been lurking
6684 around for a long time? A little for loop fix in server's
6685 silc_server_command_whois_parse that is used by both IDENTIFY
6686 and WHOIS command. At least, this was a clear bug and a cause
6687 of one type of [<unknown>] buglet.
6689 * WHOIS and IDENTIFY commands call the function
6690 silc_server_command_[whois/identify]_check function even if
6691 we are not router server.
6693 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6695 * Added --with-gmp configuration option. If set the GMP
6696 is always compiled in the SILC source tree. If not set then
6697 it is checked whether the system has the GMP3 installed. If
6698 it has then the GMP won't be compiled (the system's headers
6699 and library is used), if it doesn't have it then the GMP is
6700 compiled in the SILC source tree.
6702 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Changed RSA private exponent generation to what PKCS #1
6705 suggests. We try to find the smallest possible d by doing
6706 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6707 not security fix but optimization.
6709 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Added new config entry [Identity] to fork the server and run
6712 it as specific user and group. A patch from Bostik.
6714 * Imported Dotconf configuration library into lib/dotconf.
6715 This will be used to create the SILC configuration files later.
6716 It will appear in the distsribution after this commit.
6718 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * A big code auditing weekend happening. Auditing code for
6721 obvious mistakes, bugs and errors. Also, removing any code
6724 Removed files for being obsolete:
6726 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6727 inline in the file lib/silcutil/silcbuffer.h)
6729 o lib/silcutil/silcbufutil.c (the header has inline versions)
6731 Changed code to fix possible error conditions:
6733 o The buffer formatting routines now check that the destination
6734 buffer really has enough space to add the data. This applies for
6735 both buffer formatting and unformatting
6736 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6737 unformatting was changed to accomodate following rules:
6738 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6739 sent to the function while XXX_*STRING will not allocate or copy
6740 the data into the buffer. Instead it sets the pointer from the
6741 buffer into the pointer sent as argument (XXX_*STRING used to
6742 require that the pointer must be allocated already). This change
6743 makes this whole thing a bit more consistent and more optimized
6744 (note that the data returned in the unformatting with XXX_*STRING
6745 must not be freed now). The routines return now -1 on error.
6747 o Tried to find all code that use buffer_format and buffer_unformat
6748 and added return value checking to prevent formatting and
6749 especially unformatting errors and possible subsequent fatal
6752 o Changed ske->x and ske->KEY to mallocated pointers in
6753 lib/silcske/silcske.h. Fixed possible data and memory leak.
6755 o Added return value checking to all *_parse* functions. Fixed
6756 many memory leaks as well.
6758 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6759 so that buffer overflows would not happen. All code now also
6760 checks the return value as it can fail.
6762 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Added reconnection support to server if the normal server looses
6765 its connection to the router (for example if router is rebooted).
6766 The server performs normal reconnection strategy implemented
6767 to the server. Affected file silcd/server.c.
6769 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Added new packet type SILC_PACKET_SET_MODE that is used to
6772 distribute the information about changed modes (for clients,
6773 channels and clients channel modes) to all routers in the
6774 network. Updated the protocol specification accordingly.
6776 Added functions into silcd/packet_send.c and
6777 silcd/packet_receive.c: silc_server_send_set_mode,
6778 silc_server_set_mode.
6780 Added new files silcmode.[ch] into lib/silccore that implements
6781 the encoding and decoding of Set Mode Payload. Added new type
6782 SilcSetModePayload. Moved the definitions of different modes
6783 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6785 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Oops, a little mistake in server's connection authentication
6788 protocol. The protocol is not ended with FAILURE but with
6789 SUCCESS if the authentication is Ok. :) Affected file is
6792 * Implemented NICK_CHANGE notify handling in server in the file
6793 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6794 the local clients on the channel. After the changing nickname
6795 in router environment snhould work and the [<unknown>] nickname
6796 should appear no more.
6798 The silc_server_replace_id function that receives the Replace ID
6799 payload now sends the NICK_CHANGE notify type also in the file
6800 silcd/packet_receive.c
6802 * Changed WHOIS and IDENTIFY command to support the maximum amount
6803 of arguments defined in protocol specs (3328 arguments). This
6804 fixed a bug that caused problems when there were more than three
6807 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Added extra parameter, command identifier, to the
6810 silc_client_send_command so that explicit command identifier
6813 Changed that ID list routines uses specific command identifier
6814 when sending WHOIS/IDENTIFY requests to the server so that they
6815 can be identified when the reply comes back.
6817 Affected files lib/silcclient/command.[ch],
6818 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6820 * Added `sender' argument to silc_server_packet_send_to_channel
6821 to indicaet the sender who originally sent the packet to us
6822 that we are now re-sending. Ignored if NULL. Affected file
6823 silcd/packet_send.[ch].
6825 * Added some server statistics support in silcd/server_internal.h
6826 SilcServerStatistics structure and around the server code. Also
6827 send some nice statistics information when client is connecting
6830 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Fixed channel ID decoding in server's JOIN command reply in
6833 silcd/command_reply.c
6835 * Fixed braodcasting of replace ID payload to not to send it if
6836 we are standalone server in silcd/packet_receive.c.
6838 * Fixed all channel message sending routines to not to send
6839 packets to clients that has router set, since they are routed
6840 separately in the same function earlier. Affects file
6841 silcd/packet_send.c and all channel packet sending functions.
6843 * In USERS reply, res_argv[i] are not allocated, the table
6844 is allocated. Thus changed that free the table, not its
6847 * In server's whois_check and identify_check if the client is
6848 locally connected do not send any WHOIS commands - they are not
6851 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Fixed some minor bugs in client when sending WHOIS command. The
6854 arguments was in wrong order.
6856 * Removed statis function add_to_channel from server in
6857 silcd/command.c that was previously used with the joining but
6860 * Tested USERS command in router environment successfully with two
6861 routers, two servers and two clients.
6863 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Reorganized the USERS command and command reply in client library
6866 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6867 When the command is given by user we register a pending command
6868 callback that will reprocess the command after the reply has been
6869 received from the server. When reprocessing the packet we then
6870 display the information. Thus, the USERS information is displayed
6871 now in the command callback instead of in the command reply
6872 callback. The processing of the command is same as previously
6873 when server has sent the command reply in the JOINing process.
6875 * Added to USERS command in silcd/command_reply.c to join the client,
6876 we didn't use to know about, to the channel after we've created
6877 a client entry for it. Also, for clienet we did know already still
6878 check whether it is on the channel or not and add it if not.
6880 * Removed silc_server_command_join_notify as the function and its
6883 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6885 * Changed the client's pending command handling to the same as the
6886 server's pending command handling. It is also now possible to
6887 execute command reply functions from other command reply
6888 function as the function callbacks for commands and command
6889 replies are one and same. The pending commands are not static
6890 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6891 in client connection context. Thus, pending commands are server
6892 connection specific as it is convenient.
6894 Changed the function silc_client_command_pending and
6895 silc_client_command_pending_del and added new function
6896 silc_client_command_pending_check. Removed the
6897 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6900 * Added cmd_ident, current command identifier, to the client
6901 connection context in lib/silcclient/client.h to keep track on
6902 command identifiers used in command sending. Client's command reply
6903 function handling now supports the mandatory command identifiers.
6905 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6906 funtions in client to fully support pending command callbacks.
6908 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6909 as one of the arguments to the application in the command reply
6912 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6913 before first releasing SILC but came back. Now it is removed again
6914 and should come back nomore. The FORWARDED flag was used only
6915 by the JOINing procedure by forwarding the command packet to router.
6916 Now, the JOINing procedure has been changed to more generic (due
6917 to various router environment issues) and FORWARDED is not needed
6918 anymore for anything. The protocol specification is yet to be
6921 Now, removed silc_server_packet_forward from server and the flag
6922 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6924 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Renamed NAMES command to USERS command. The NAMES was named that
6927 due to historical reasons. Now it is renamed. Also, rewrote
6928 parts of the USERS command. The nickname list is not sent anymore
6929 by the server. Only Client ID and mode lists are sent in the USERS
6930 command. Changed this also to the protocol specification.
6932 The client now resolves the names and stuff after it receives
6933 the USERS list from the server when joining to the channel.
6935 * WHOIS and IDENTIFY commands has been changed to support multiple
6936 Client ID's per command. One can now search for multiple users
6937 in the network by sending only one WHOIS or IDENTIFY command.
6938 Changed the code and the protocol specifications.
6940 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6941 uses silc_server_command_whois_parse to parse the request. */
6943 * If normal server, do not parse the WHOIS and IDENTIFY requests
6944 before sending it to the router. Saves some time.
6946 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Fixed JOIN command on client library. Wrong number of arguments
6949 used to crash the client.
6951 * Added silc_server_channel_has_global function to check whether
6952 channel has global users or not.
6954 * Added silc_server_channel_has_local function to check whether channel
6955 has locally connected clients on the channel.
6957 * The silc_server_remove_from_one_channel now checks whether the
6958 channel has global users or not after given client was removed from
6959 the channel. It also checks whether the channel has local clients
6960 on the channel anymore. If it does not have then the channel entry
6961 is removed as it is not needed anymore.
6963 * The silc_server_notify now checks on JOIN notify whether the joining
6964 client is one of locally connected or global. If it is global then
6965 the channel has now global users on the channel and that is marked
6966 to the channel entry. Also, it now saves the global client to
6967 global list who is joining and JOINs it to the channel. This is
6968 for normal server, that is.
6970 Changed silc_server_send_notify_on_channel,
6971 silc_server_packet_relay_to_channel and
6972 silc_server_packet_send_to_channel check if we are normal server
6973 and client has router set (ie. global client) do not send the
6974 message to that client, as it is already routed to our router.
6976 * Implemented LEAVE notify type handling in silc_server_notify
6979 * Tested LEAVE command in router environment successfully. Tested
6980 with two routers, two servers and two clients.
6984 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6986 * Implemented SIGNOFF notify type handling in silc_server_notify
6989 * silc_server_remove_id now removes the client entry from all channels
6990 it has joined and thusly sends SIGNOFF notify type.
6992 * Rewrote the NAMES list generation in server by removing two excess
6993 loops. The lists are created now inside one loop.
6995 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * silc_server_remove_channel_user checks now also global list
6998 for channel and client.
7000 * silc_server_new_channel_user checks now both local and global
7001 list for channel and client. Fixed a bug in client id decoding.
7002 Used to decode wrong buffer.
7004 * silc_server_channel_message checks now both local and global
7005 list for channel entry.
7007 * Tested channel joining (hence JOIN) in router environment
7008 successfully. Tested with two routers, two servers and two
7011 * Tested channel message sending in router environment successfully.
7013 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * Added silc_server_save_channel_key into server.[ch] to save the
7016 received channel key in Channel Key payload processing. It is
7017 also used in JOIN command reply handling.
7019 Equivalent function silc_client_save_channel_key added into
7020 client.[ch] into client library.
7022 * Changed JOIN command reply to send information whether the channel
7023 was created or not (is existing already) and the channel key
7024 payload. Changed protocol specs accordingly.
7026 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7027 the request was sent by ID and not by nickname. Crashed on
7030 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7033 now correctly save the received data.
7035 * silc_server_free_sock_user_data now notifies routers in the
7036 network about entities leaving the network.
7038 At the same time implemented functions silc_server_remove_id
7039 and silc_server_send_remove_id to receive and send REMOVE_ID
7040 packets. The packet is used to notify routers in the network
7041 about leaving entities. The ID removed will become invalid in
7044 * Added function silc_idlist_del_server into server. Removes and
7045 free's server entry from ID list.
7047 * silc_server_private_message function now checks, if we are router,
7048 that the destination ID really is valid ID, naturally.
7050 * In router when NEW_ID packet is received (for new client) the
7051 hash of the Client ID is saved in the ID Cache but the
7052 client->nickname is set to NULL, instead of putting the hash
7055 IDENTIFY command now also checks that client->nickname must be
7056 valid. If it is not if will request the data from the server who
7057 owns the client. Added new function
7058 silc_server_command_identify_check.
7060 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7061 to set the command to already allocated Command Payload.
7063 * Tested private message sending in router environment with two
7064 routers, two servers and two clients. Fixed minor bugs and now
7067 * Fixed segfault from client's NAMES command. Used to crash if
7070 * Forwarded packets must not be routed even if it is not destined
7071 to the receiver. Changed server code comply with this.
7073 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Added `require_reverse_mapping' boolean value to ServerParams
7076 structure. If TRUE (not default) the server will require that
7077 the connecting host has fully qualified domain name.
7079 If the reverse mapping is not required and hostname could not be
7080 found the IP address is used as hostname.
7082 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * Implemented version string checking to both client and server.
7085 The check is incomplete currently due to the abnormal version
7086 strings used in development version of SILC.
7088 * Changed all command functions in server to use the new
7091 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Changed char *data to unsigned char *data in ID Cache system to
7094 support binary data as ID Cache data. Changed code to support
7095 binary data in lib/silccore/idcache.c.
7097 * Renamed silc_server_packet_relay_command_reply to
7098 silc_server_command_reply as it is normal packet receiving
7099 function. Rewrote the function to accept command replys for
7100 servers and not only for clients.
7102 * Mark remote router always as registered server if we are connecting
7103 to it. Otherwise, commands sent by the router to us are ignored.
7105 * All ID List find routines now returns the ID Cache Entry pointer
7106 as well if requested.
7108 * WHOIS command works now in router environment, tested with two
7109 routers, two servers and two clients.
7111 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7112 in router environment (as it is almost equivalent to WHOIS) but
7113 hasn't been tested thoroughly. Added new functions:
7115 silc_server_command_identify_parse
7116 silc_server_command_identify_send_reply
7117 silc_server_command_identify_from_client
7118 silc_server_command_identify_from_server
7120 * Disabled route cache adding because adding two different ID's with
7121 same IP replaces the old cache entry thus giving wrong route.
7122 The entry->router->connection is always the fastest route anyway
7123 so route cache may not be needed. Of course, new routes maybe
7124 established after receiving the ID when the entry->router->connection
7125 might not be anymore the most optimal.
7127 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Add route cache for received ID for fast routing.
7131 * Added silc_server_packet_route to route received packet on router
7132 that is not destined to us.
7134 * Renamed silc_server_get_route to silc_server_route_get.
7136 * Added id_string and id_string_len fields into SilcServer to
7137 include encoded ServerID for fast comparing without excess
7138 encoding of the ID's.
7140 * Cleaned up WHOIS command on server side. Added following static
7143 silc_server_command_whois_parse
7144 silc_server_command_whois_check
7145 silc_server_command_whois_send_reply
7146 silc_server_command_whois_from_client
7147 silc_server_command_whois_from_server
7149 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7150 arguments in command replies. All command functions should be
7151 updated to use this macro.
7153 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Minor typo fixes on command reply handling on server.
7157 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * Added silc_server_command_add_to_channel internal routine to add
7160 the client to the channel after router has created the channel and
7161 sent command reply to the server.
7163 * Added generic silc_server_send_command to send any command from
7166 * Use static buffer with ID rendering instead of duplicating data.
7168 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7170 * Fixed a channel user mode bug when joining to a channel server gave
7171 everybody channel founder rights, oops.
7173 * We mark ourselves as the router of the incoming server connection
7174 if we are router ourselves. This way we can check in some packet
7175 sending functions whether it is locally connected server. For
7176 incoming router connections we put NULL.
7178 * For router sending packets locally means now always sending the
7179 packet cell wide; to local clients and local servers. For normal
7180 server sending packet locally means sending it to only local
7183 * Fixed the JOIN command to really work in router environment. If the
7184 channel is created it is always created by the router. Router is
7185 also responsible of making the initial joining to the channel,
7186 sending JOIN notify to the sending server and distributing
7187 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7188 does not exist server doesn't do anything else but forward the
7189 command to the router which performs everything.
7191 * Added silc_server_send_channel_key function to send the Channel Key
7194 * Added silc_server_create_channel_key to create new channel key. The
7195 channel key is now re-generated everytime someone joins or leaves
7196 a channel, as protocol dictates. Note: channel->key_len is the
7199 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7201 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7202 packet_receive.[ch] to separate packet sending and receiving
7203 routines. The server.[ch] now includes everything else including
7204 actual packet processing (writing and reading data) and other
7207 Renamed silc_server_private_message_send_internal to
7208 silc_server_send_private_message. The routine is still though
7209 used only to relay private messages as server does not send
7210 private messages itself.
7212 Renamed silc_server_new_channel to silc_server_create_new_channel
7213 and added new function sicl_server_new_channel that handles the
7214 incoming New Channel packet. Added also new sending function
7215 silc_server_send_new_channel to send New Channel Payload.
7217 * Added new function silc_server_notify to process incoming notify
7218 packet to the server/router. Server may then relay the notify
7219 to clients if needed.
7221 * Added new function silc_server_new_channel_user to process incoming
7222 New Channel User packet. Router will redistribute the packet and
7223 send JOIN notify to its local clients and locally connected servers
7224 if needed. Normal server will send JOIN notify to its local client
7225 on same channel when received this packet. Added also corresponding
7226 sending function silc_server_send_new_channel_user to sent the
7229 * Added boolean route argument to send_notif_to_channel and
7230 packet_send_to_channel functions to attempt to route the packet
7231 if it is TRUE and send only locally if it is FALSE.
7233 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * silc_server_replace_id now broadcasts the received replace ID
7236 packet if it is not broadcast packet already. The router must
7237 broadcast to inform other routers about changed ID.
7239 * Added backpointer to server's router into SilcServer context in
7240 silcd/server_internal.h.
7242 * Fixed silc_server_packet_broadcast to send correct broadcast
7245 * The channel key is now distributed to the local client as soon
7246 as it is received from the router (in router environment) so that
7247 no other packet may be sent for the channel until client has
7250 * silc_server_remove_channel_user now broadcasts the received
7251 Remove Channel User packet if it is not broadcast packet already.
7252 The router must broadcast to inform other routers about removed
7255 * Added users field into SilcPacketContext that is a reference count
7256 of the context. One can increase the reference count by calling
7257 silc_packet_context_dup which is now changed to just increase the
7258 reference count instead of duplicating the data. The reference
7259 count is decresed by calling silc_packet_context_free that will
7260 free the data after the reference count hits zero.
7262 For now on the packet context and everything allocated into it
7263 (including the raw packet from network) must be freed by calling
7264 the new silc_packet_context_free function. Added also new function
7265 silc_packet_context_alloc that must be used now to allocate the
7266 context. This also means that if a routine is asynchronous from
7267 silc_[client/server]_packet_parse_type the packet context must
7268 be duplicated by calling silc_packet_context_dup. Otherwise it
7269 gets free'd after silc_[client/server]_packet_parse_type returns.
7270 Also, one must remember that if packet is duplicated then its
7271 reference count must be decresed by calling the free function as
7272 many times as it was duplicated.
7274 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7275 from both client and server.
7277 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Made joining to a channel working in router environment.
7281 * Cleaned up JOIN command on server side and create function
7282 silc_server_command_join_channel internal routine to make the
7285 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7287 * Changed silc_command_pending list to SilcDList. Also, added
7288 `ident' field to SilcServerCommandPending structure to identify
7289 the reply and to call correct callback.
7291 Added silc_server_command_pending_check function to replace the
7292 corresnponding macro. The silc_command_pending list is not
7295 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7296 to set identifier to previously allocated Command Payload. It
7297 is used to set identifier for command when resending Command
7300 * Added silc_command_payload_encode_payload to encode Command
7301 Payload buffer from SilcCommandPayload structure.
7303 * Added silc_argument_payload_encode_payload to encode Argument
7304 payload buffer from SilcArgumentPayload structure.
7306 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Changed WHOIS command to support router connection on server side.
7309 The whois request is always sent to router unless the server is
7310 standalone server. After server has received the reply from the
7311 router will it send the reply to the client.
7313 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7314 broadcast received broadcast packet. The function is used only
7315 by router. The broadcast packet is always sent to the router's
7318 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7319 render given ID to printable string, for log files for example.
7321 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7323 * Made basic router to router connections working. At least they
7324 can now connect to each other but nothing really works the way
7325 they are supposed - yet.
7327 * Added new initiator token to RouterConnection configuration
7328 file in silcd/serverconfig.[ch]. It is used to tell whether we
7329 are the initiator to the remote router or whether we'll expect
7330 the other end to connect.
7332 * Moved registering of listener task to silc_server_init, hence
7333 the server starts listenning as soon as it is run, even if it
7334 does not have connections to other routers. Let's see how well
7337 * Changed default connection retry timeouts for more suitable in
7340 * Removed cipher and such arguments from silc_idlist_add_client
7341 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7342 Added new function silc_idlist_add_data to add the keys and stuff
7345 * Added SilcIDListData structure and added it to SilcClientEntry
7346 and SilcServerEntry as their first field in the structure. This
7347 way we can explicitly cast the ID entries to the SilcIDListData
7348 structure and get common data for the entries. In past, we had
7349 to first check what type of connection it is and then cast it to
7350 correct ID entry type. Now, we can directly cast the opaque
7351 pointer to the SilcIDListData (no matter what ID entry it actually
7352 is) and get the data needed.
7354 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7357 in some circumstances even if threre were timeout tasks, though not
7358 IO tasks, but tasks anyway. Now fixed.
7360 * Defined SilcServerConnection structure to hold connection specific
7361 stuff about directly connected servers and routers. The definition
7362 is currently in silcd/server_internal.h. I thought about having
7363 a bit more important role fro this struct but for now it is used
7364 only when connecting to other server (or router actually).
7366 * Added connecting retry support in server when connecting to
7367 router(s). The retry feature implement exponential backoff
7368 algorithm. Also, added SilcServerParams structure to hold default
7369 parameters for server. For now, it include these retry settings
7370 and are hard coded. After server is moded to be as Silc Server
7371 Library this structure will be more important.
7373 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Changed client librarys channel->clients table to SilcList and
7376 changed code accordingly.
7378 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Changed client's channel table to SilcList and changed code
7381 accordingly. Also changed SilcChannelClientEntry to include back-
7382 pointer to the channel so that client entry can use that structure
7383 as list as well and we have fast cross-reference to the channel.
7384 This change dramatically decreased the complexity of channel
7385 handling with client entry and vice versa (removed one extra
7386 loop when searching for channel entry from many functions).
7388 * Changed server->sim from table to SilcDList and changed code
7391 * NAMES command can now be used from user interface. It will show
7392 the user list on the channel, neatly.
7394 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7395 Code now saves realname of the user if it becomes available.
7397 * Renamed configure.in to configure.in.pre and made ./prepare
7398 script to automatically add correct version string to
7399 configure.in which it creates from configure.in.pre.
7401 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7403 * NAMES command reply now shows users mode with the nickname when
7406 * Moved silc_client_ch[u]mode[_char] functions from
7407 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7408 place sucks, they are utility functions and should be in some
7411 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7413 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7416 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * Added TRQ (efficient deque and list library) into lib/trq. This is
7421 a very good list library that is currently used in the SILC. Defined
7422 SilcList API over the library because I didn't like the API very
7423 much. See lib/trq/silclist.h for the API and examples of how to
7424 use the API. Fixed various places in the code to use the new
7425 SilcList API. The SilcList is meant for lists that has a structure
7426 already defined as a list. It is not suitable to add just some
7427 context to the list (in TRQ, the context is the list actually).
7429 So, I defined SilcDList that can be used for the purpose where
7430 predefined list structure does not exit. This can be used as
7431 such list. Now some context just can be added to the SilcDList.
7432 Currently this list is not used in the SILC just yet, though there
7433 are a lot places where this can replace dynamically allocated
7434 tables and I will fix these places, later, to use SilcDList.
7435 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7436 and use TRQ internally).
7438 Also fixed some annoying warning messages that the original TRQ
7439 code generated. Also minor changes to TRQ's Makefile.in.
7441 * Added support for querying by Client ID to both WHOIS and
7442 IDENTIFY commands into server, as required by the protocol.
7444 * Removed method function pointers from SilcBuffer structure. They
7445 weren't used to anything and just increased the context size for
7446 no good reason. This change also made silc_buffer_alloc and
7447 silc_buffer_free functions inline functions.
7449 * Disabled command flooding detection support until it's fixed so
7450 that it accepts commands in but does not execute them more than once
7453 * Added silc_net_localhost(), to return local hostname, into
7454 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7455 that must be initialized before calling silc_client_init.
7457 * Added new function: silc_server_send_notify_on_channels to send
7458 notify messages to all channels client has joined. It is assured
7459 that the message is sent only once per client.
7461 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7462 lib/silcutil/silcutil.[ch] as silc_format function. The new
7463 function is generic and is used by server as well, not only by
7464 the logging routines.
7466 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7467 the provided version string was not acceptable. Added new function:
7468 silc_ske_check_version into lib/silcske/silcske.h. The function
7469 must be implemented by the application (client or server) and it
7470 does not reside in the SKE library. The function checks the version
7471 string remote end sent.
7473 * Added back pointers (to opaque context and to SilcSocketConnection)
7474 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7476 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7477 duplicate packet context structure.
7479 * Changed `notify' client operation to send same arguments as client
7480 receives from server except for ID's. ID's are mapped to correct
7481 ID entry and that is returned. Also, if channel entry is not sent
7482 by server but the notify is for channel the channel entry is sent
7483 to application (otherwise application doesn't know that it is for
7484 channel (library gets it from packet's Destination ID)).
7486 * Added silc_client_remove_from_channels into client library to
7487 remove a client from all channels it has joined to. Used when
7488 received SIGNOFF notify from server. Added also new function
7489 silc_client_replace_from_channels to replace old ID entry with
7490 new ID entry on all channels. Used when received NICK_CHANGE
7493 * Fixed ID Cache list handling in silc_idlist_get_client in
7494 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7495 to get (or query) client by ID.
7497 * Updated TODO list.
7499 * Added connection authentication status message defined by the
7500 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7501 support for these into the code in client and server side.
7503 * Added generic function silc_client_send_command to send any command
7504 with variable argument list. Application should use this function
7505 to send commands if the command functions provided by the library
7506 does not suite for the application's user interface needs.
7508 * Added new `failure' client operation. Application is notified about
7509 received failure packet if client is executing a protocol. In this
7510 case the protocol's execution has failed.
7512 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7513 is required by the protocol.
7515 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7516 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7519 * Added status flag to SilcSKE object to indicate realtime status
7520 of the SKE protocol.
7522 * Application receives now exactly same command reply arguments as
7523 the library receives from server. However, if ID is received the
7524 corresponding ID entry is returned to the application (eg. Client
7525 ID is mapped to correct SilcClientEntry entry and that is returned).
7526 Changed command_reply client operation due to this change.
7528 * Changed all ID's in commands and in command replys as ID Payloads.
7529 Change affected both client and server side codes.
7531 All ID's sent in SILC network (with execption of ID's in SILC
7532 Packet header) are sent in ID Payload to support variable length
7535 * Server now notifies nick changes and notifies all clients on
7536 the channels about the new nickname (about the new Client ID,
7539 * Implemented CMODE command to change channel modes. Supports all
7540 channel modes defined by the protocol specs except ban and invite
7541 lists. (Also, private channel key mode is supported but support for
7542 setting private channel key in client is missing, thus, this mode
7543 has no effect on client side (except that server requires that the
7544 client uses private channel key and normal channel traffic does not
7547 Also, invite mode works per se, but INVITE command does not work
7548 yet correctly, so you can set channel as invite only channel but
7549 inviting clients to the channel does not work (it is yet to be
7550 thought what's the best way to do it).
7552 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7553 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7554 Implemented CUMODE command to change user's mode on the channel.
7555 Supports all modes defined by the protocol specs.
7557 * Added NAMES command reply to return users modes on the channel.
7559 * Removed unnecessary and slow ciphers from lib/silccrypt.
7561 * Set SO_KEEPALIVE option to connection sockets by default.
7563 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7565 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7566 redefined the Notify Payload into protocol specs.
7568 * Added silc_id_payload_parse_id to get ID directly from raw
7571 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7573 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7574 accept searching by Client ID as well.
7576 * Added support for LEAVE and SIGNOFF notify types in client library.
7578 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7579 to parse ID Payload from raw data.
7581 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7583 * Added flags parameter into silc_ske_assemble_security_properties
7584 function in lib/silcske/silcske.[ch].
7586 * Changed notify client operation to fit better for notify messages
7587 sent by server. The notify payload received from server is now
7588 passed to the application (after parsing it to SilcNotifyPayload).
7589 It is application's responsibility to retrieve the arguments
7590 from the payload and show the message the way it wants. The message
7591 sent by server is implementation specific.
7593 * Changed public keys to comply with the protocol specification.
7594 Old public keys are not supported anymore and are not compatible.
7596 * Removed nickname from Channel Payload as the latest draft removed
7597 it. The client must resolve the nickname from the NAMES command
7598 reply received when it joined the channel.
7600 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7602 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7604 * Fixed some errors in protocol specification drafts.
7606 * Created lib/silccore/silcnotify.c to implement Notify Payload
7607 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7608 generic payloads described by protocol specifications. The file
7609 includes implementations for ID Payload and Argument Payload.
7611 * Changed Command Payload implementation to use the new Argument
7612 Payload. Changed command_xxxx_payload to command_payload_xxxx
7613 to comply with SILC coding conventions.
7615 * Added suppport for Argument Payload handling in Notify Payload
7616 implementation as protocol requires it. Added the new support
7617 into server and client lib as well.
7619 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7621 * Added support for multiple nicknames on same channel. [n] is
7622 added locally to the nickname if there are more than one same
7623 nicknames on the channel.
7625 * Server now sends all nicknames that matched WHOIS request.
7626 Client also shows the list received from server.
7628 * Added TOPIC command to client side. User can now set and show
7629 current topic on channel.
7631 * Added MOTD command to client and server. Also, server sends the
7632 motd when client connects to the server.
7634 * Changed version strings to comply ISO 8601.
7636 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7638 * Fixed protocol error handling in client library. It should now
7639 cope even if the SKE fails for some reason.
7641 * Made new protocol specification drafts for submitting to IETF.
7643 * Implemented TOPIC command to server in silcd/command.c.
7645 * Added two new notify types into lib/silccore/silcnotify.h:
7646 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7647 notify nickname change and topic setting/change on a channel.
7649 * API change of command_reply operation in client library. The
7650 application gets now the status type received from server as well.
7652 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7654 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7656 * Cras fixed and optimized the packet handling even further and
7657 it should work now. Minor change to the prototype of function
7658 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7660 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7662 * Added new function into lib/silcutil/silcschedule.[ch]:
7663 silc_schedule_with_fd to select() a specified fd. The function
7664 returns after timeout expires or data arrives or goes. The
7665 function is used by packet routines to wait that all data is
7666 received from network.
7668 * Fixed data reading from network in lib/silccore/silcpacket.c.
7669 The code now assures that all data is read from the fd and then
7670 continues packet processing. This was a bug fix since the code
7671 used to drop some data in some circumstances.
7673 * Added new function into lib/silcclient/client.[ch]:
7674 silc_client_start_key_exchange to start key exchange after
7675 connection has been established to server. The code internally
7676 now uses this funtion but its main purpose was to provide it
7677 for applications that perform their own connecting. After
7678 application has created a connection it merely calls this
7679 function to start the key exchange between client and server.
7680 The library takes care of everything else after that.
7682 Updated also lib/silcclient/README to explain the usage of
7685 * Do not send to application information that connection has
7686 been established. Application gets notified it by connect
7689 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Applied cras's patch to add silc_schedule_one function. The
7692 function runs scheduler once and returns.
7694 * Fixed the scheduler after cras messed it up. The timeout
7695 handling works now as it's supposed to work.
7697 * Added into lib/silccore/ silcnotify.h to include notify
7698 message types support. Changed silc_server_send_notify*
7699 functions, in server.[ch], to support those new notify types.
7700 Added the support for the notify types into client library,
7701 as well. Added new notify client operation into ops.h in
7704 * Changed silc_server_packet_send_to_channel to send normal
7705 packets instead of just channel message packets. The function
7706 is now used to send the notify packets to channels. It is not
7707 used to send channel message packets anymore, as server never
7710 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7711 va_arg()s as it seems to require it nowadays. I guess, if SILC
7712 is compiled with older va_arg() the new code should work anyway.
7714 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7716 * Splitted core library. Core library (lib/silccore) includes
7717 now only SILC protocol specific core (and common) components.
7718 Created new utility library (lib/silcutil) that includes more
7719 generic purpose stuff. The stuff for util library was taken
7720 from the old core library. This was minor and easy split.
7722 * Created SILC Client Library (lib/silcclient) that includes
7723 implementation of the SILC client without user interface. This
7724 was major move from silc/ directory. The code has been changed
7725 so that it is transparent towards the user interface. The
7726 silc/ directory includes now the same user interface as before
7727 and it uses the new client library. Read lib/silcclient/README.
7728 Basicly, the client library performs everything else related
7729 to SILC except user interface handling. Also, configuration
7730 files are considered to be part of user interface and library
7731 does not handle them.
7733 This change also changed a lot of structures, function naming etc.
7734 Most important change was that SilcClientWindow object was
7735 renamed to SilcClientConnection in the client library. Created
7736 also new file lib/silcclient/ops.h. Also added new files
7737 silc/local_command.[ch] and silc/client_ops.[ch].
7739 All these changes were made to make it easier for user interface
7740 designers to create what ever user interface for the SILC client
7743 It is also expected that the server will be moved to lib
7744 directory as well and SILC Server Library will be created;
7745 sometimes in the future.
7747 * Removed Local commands from lib/silccore/silccommand.h as
7748 they are application specific and new client library does not
7749 handle any of those anymore.
7751 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7752 old client implementation in silc/.
7754 * Added support for callback functions in SILC_LOG_* macros.
7755 Application can now set its own callbacks that will be called
7756 instead of using the default functions that will always print
7757 the debug messages to stderr (or stdout). Also, debugging can
7758 now be disabled by setting silc_debug to FALSE and re-enabled by
7759 setting it to TRUE. Note, that logging will still work even
7760 if debugging is disabled.
7762 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7763 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7764 silc_log_reset_debug_callbacks.
7766 * To enable debugging in silc client one must give now -d
7767 option on command line.
7769 * Changed silc_schedule_init to automatically allocate task queues
7770 if they are not allocated before calling it.
7772 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7774 * Added GMP 3.1 into math library.
7776 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7779 a channel in SILC network. The packet is used by servers and
7780 routers to notify other routers that user has left a channel.
7781 This little feature was missing until now. Added the feature
7782 to protocol specification as well.
7784 Added functions: silc_server_send_remove_channel_user and
7785 silc_server_remove_channel_user into server.[ch].
7787 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7788 lib/silccore/silcpacket.h. However, they are not implemented
7791 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Fixed joining to a channel and sending channel messages
7794 between server and router. The channel message sending should
7795 now work inside a cell.
7797 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Fixed the private message sending between server and router.
7800 The private message sending should now work inside a cell.
7802 * Added silc_server_replace_id into server.[ch] to replace
7803 existing ID in the SILC network.
7805 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7806 and silc_idlist_replace_server_id into idlist.[ch] in server.
7808 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7810 * Fixed the server to server connections. Server can again now
7811 connect to router. Router to router connections probably does
7814 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7816 * Added dynamic protocol registering support. Now protocols can
7817 registered and unregistered on the fly. Patch by cras.
7819 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7821 * Added lib/contrib directory to hold routines that some platforms
7822 don't have but are needed by SILC.
7824 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7825 into lin/contrib to provide getopt() and getopt_long() for
7826 those who don't have it.
7828 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7830 * Added AWAY command to client. When away message is set and
7831 client receives a private message packet the client automatically
7832 replies to the sender with the away message.
7834 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7835 bug seemed to be the cause of recent problems when compiling
7838 * Added version detection support to SKE protocol specification
7839 and added the new changes to the SKE implementation as well.
7840 There were other minor changes in the SKE protocol as well.
7842 Many changes in lib/silcske/silcske.[ch] and in
7843 lib/silcske/payload.[ch].
7845 * Added ^U functionality, clear input line. Patch from cras.
7847 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7849 * Mainly small bugfixes on core library. Fixed some debugging
7850 logging and buffer overflow in silclog.c.
7852 * Updated config.sub and config.guess on the distribution tree.
7854 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Added command lagging support in server. Client may execute
7857 commands now only once in two seconds.
7859 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7861 * Optimized packet reception. MAC computation and checking is now
7862 also more optimized. A lot previously duplicated code is now
7863 used as generic by both client and server.
7865 * Fixed key pair generation in clientutil.c
7867 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7869 * Added into lib/silccore/silcbufutil.[ch] new function;
7870 silc_buffer_realloc.
7872 * Moved generic packet sending/encryption functions to
7873 lib/silccore/silcpacket.[ch] from client and server. Some
7874 rewriting of the functions.
7876 * Moved all generic packet reception/decryption functions to
7877 lib/silccore/silcpacket.[ch] from client and server. The
7878 packet processing is now much cleaner in both client and server.
7879 These were major changes in both client and server.
7881 * Created many common functions in server to do packet sending.
7882 Previously code were duplicated a lot, this has been removed
7885 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7887 * Rewrote major parts of the ID cache system. Don't know
7888 whether it is better now or not but at least the API is more
7891 * Major rewrite on ID cache stuff on client because of the ID
7892 cache API changes. Added idlist.c to client.
7894 * Also major rewrite on ID cache stuff on server as well.
7895 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7896 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7897 in hand, instead they are all put into the ID cache system now.
7898 All server_idlist_* routines uses ID cache now instead of
7899 traversing its own lists (those lists does not exist anymore).
7900 SilcIDList though still exists. Also, SilcXXXEntry's are
7903 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7905 * Finally made the SKE implementation compliant to the protocol
7906 specification. All mp integers are now binary encoded as
7907 opposed being HEX encoded.
7909 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7912 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7913 functions: silc_[encode/decode]_pem. Also added function
7914 silc_encode_pem_file to PEM encode with newlines ('\n') for
7917 * SILC public keys are now encoded either PEM or binary. Same
7918 option is for private keys as well. By default private keys
7919 are binary encoded and public keys PEM encoded. Silly HEX
7920 encoding were removed.
7922 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7923 function to create fingerprints.
7925 * Fixed a bug in SHA1; does not change the original data anymore.
7927 * Partly implemented INFO command on client and server side.
7928 Fixed CLEAR command. Changes to SERVER command; show current
7929 server(s) when giving command without arguments. Added
7930 VERSION command to client.
7932 * Added check to server that unregistered connections cannot
7933 execute commands (unless it is specificly allowed).
7935 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7937 * Fixed screen refresh.
7939 * Fixed channel joining bug from client. On some circumstances
7940 client tried to join to a channel it had already joined.
7942 * Added public key verification process into client's protocol.c.
7943 The client now verifies the public key from user and saves
7944 it into ~./silc/serverkeys/ directory.
7946 Added into: clientutil.[ch]: silc_client_verify_server_key.
7948 * Changed SKE protocol's silc_ske_initiator_finish function
7949 to accept callback function that verifies the received public
7950 key. Removed old silc_ske_verify_public_key function.
7952 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7954 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7955 silc_pkcs_private_key[_data]_set.
7957 * Made the password and public authentication more cleaner in
7958 server's protocol.c.
7960 * Removed historic and obsolete protocol `channel_auth' from
7961 both client and server.
7963 * Removed wrong way of sending command status messages from
7964 server to client in server's command.c. The old way violated
7965 protocol specification.
7967 Changes to silccore/silccommand.[ch]: removed
7968 silc_command_encode_status_payload -> not needed anymore,
7969 changed silc_command_encode_payload_va to accept extra
7970 argument on variable argument list. The argument type must
7971 now be provided to the function. Also, added new function:
7972 silc_command_encode_reply_payload_va which is same as
7973 normal command_encode_payload_va except command status type
7974 is provided as extra argument.
7976 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Added ~./silc directory handling. The directory includes the
7979 public and private keys for the client.
7981 Added silc_client_check_silc_dir, silc_client_create_identifier
7982 and silc_client_load_keys.
7984 * Implemented SILC protocol compliant public key. Added public
7985 and private key saving to and loading from files.
7987 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7988 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7989 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7990 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7991 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7993 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7994 silc_pkcs_load_[public/private]_key.
7996 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7998 * Added silc_server_get_route (route.[ch]) to get connection
7999 data for the fastest route for given ID.
8001 * Implemented INVITE command on client and server. The command
8002 were re-defined in the SILC Protocol Specification and the
8003 implementation now complies with the specification.
8005 * Implemented PING command on client and server.
8007 * Implemented NAMES command on client and server. The server side
8008 supports currently only normal server not router server yet.
8009 Some changes to NAMES definition in SILC protocol specification.
8011 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8013 * Implemented LEAVE command on client and server.
8015 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
