3 * Defined that server receives WHOIS command reply for private
4 and secret channels too. Updated protocol specs and the
5 code in server. Affected file silcd/command.c.
7 * Defined <channel user mode list> argument to WHOIS command
8 reply for returning user modes on the channels. The
9 channel list now doesn't include the user mode anymore but the
10 actual channel mode. Updated protocol specs and the code in
11 client and server. Affected files are silcd/command_reply.c,
12 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
13 and lib/silcclient/command_reply.c.
15 * Save the channels list in WHOIS command reply in normal server
16 so that WHOIS always shows joined channels also in normal
17 server and not just on router. Affected file is
18 silcd/command_reply.c.
20 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

26 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
28 * Changed the UMODE's mode mask argument to be optional. If
29 not provided then the command merely returns the current mode
30 mask to the client. Updated protocol specs and the server.
31 Affected file is silcd/command.c.
33 * Added SILC session detachment/resuming support. It is possible
34 to detach by closing the network connection and then re-connect
35 and resume to the old client session. Added DETACHED user
36 mode that server will set for detached client. Added new
37 packet RESUME_CLIENT which is used to perform the resuming
38 process. Added DETACH command. Updated the protocol specs,
39 core library, client and server. Protocol TODO #22. Very
40 many affected files around the tree.
42 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
44 * Changed the CMODE's mode mask argument to be optional. If
45 not provided then the command merely returns the current mode
46 mask to the client. Updated protocol specs and the server.
47 Affected file is silcd/command.c.
49 * Changed the Killer's Client ID in KILLED notify to be just
50 any ID payload since router server is allowed to kill as well.
51 Updated protocol specs, client libary and server. Affected
52 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
53 and irssi/src/silc/core/client_ops.c.
55 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
57 * Added new user modes ANONYMOUS for special anonymous servers
58 that may set the mode for client, and BLOCK_PRIVMSG which
59 client may set to block incoming private messages unless the
60 Private Message Key flag is set (using private keys to protect
61 private messages). Updated protocol specs and code in client
62 and server and core library. Protocol TODO #23. Affected
63 files are lib/silccore/silcmode.h, silcd/server.[ch],
64 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
65 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
67 * Added new channel user mode BLOCK_MESSAGES which the client
68 may set to itself to tell server not send channel messages.
69 Other packets such as channel key packets are still sent.
70 Protocol TODO #23. Updated the protocol specs, client and
71 server. Affected files are lib/silccore/silcmode.h,
72 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
73 lib/silcutil/silcutil.c, silcd/command.c, and
76 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
78 * Redefined the Status Payload to include now two 8 bit fields,
79 instead of one 16 bit field. This now makes it possible to
80 send list of errors. Updated the protocol specs and the code
81 in core library, client library and server. Protocol TODO #1.
82 Affected files are lib/silccore/silccommand.[ch],
83 lib/silcclient/command_reply.[ch], silcd/command.c,
84 silcd/command_reply.c and silcd/packet_receive.[ch].
86 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
88 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
89 must be handled by the application and should tell the application
90 that an error message was already printed, and it should print the
91 config coords (line, filename, ...). Affected files are
92 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
94 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
95 server config parsing code more readable.
97 Fixed a bug in the fetch_logging() config callback.
99 Affected files is silcd/serverconfig.c.
101 * Drop root privileges when started in foreground. Don't drop them
102 if debugging also. Affected file is silcd/silcd.c.

110 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
111 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
113 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
115 * Added STATS command to the protocol after all, to return
116 various statistical information about the network. It can
117 be used by clients to retrieve statistical information, and
118 servers may use it to to fetch cell and network wide
119 statistics from router. Updated the protocol specs and
120 implemented it to the server. Protocol TODO #16.
121 Affected files are lib/silccore/silccommand, silcd/command.[ch],
122 silcd/command_reply.[ch].
124 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
126 * The LIST command reply in client libary now adds new channel
127 entry if the returned channel doesn't exist yet in cache,
128 and returns the channel entry to the application in the
129 command_reply client operation. Affected file is
130 lib/silcclient/command_reply.c.
132 * Changed the channel message payload's MAC generation to
133 include the IV in the MAC as well. This way all relevant
134 parts of the channel message payload are authenticated also
135 with the channel message MAC (and not only by packet MAC).
136 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
137 Affected file is lib/silccore/silcchannel.c.
139 * Fixed the SKE to save the remote version, since the
140 silc_ske_parse_version mistakenly checked wrong version,
141 after it replaced the start payload. Affected files are
142 lib/silcske/silcske.[ch].
144 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
147 string utility functions. Added there also new functions
148 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
149 Affected files lib/silcutil/silcstrutil.[ch].
151 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
152 files are lib/silcutil/silcstrutil.[ch].
154 * Defined that the security property fields in SKE SHOULD be
155 UTF-8 encoded, defined that version string MUST be US-ASCII
156 encoded, defined that passphrases sent in connection
157 authentication protocol MUST be UTF-8 encoded. Implemented
158 these to the client and server. Defined also that other
159 passphrases sent in the protocol MUST be UTF-8 encoded.
160 Affected files are lib/silcske/silcske.c,
161 lib/silcclient/protocol.c, silcd/protocol.c,
162 silcd/serverconfig.c, and lib/silccore/silcauth.c.
164 * Changed the silc_client_close_connection interface to not
165 need the SilcSocketConnection which should not be visible
166 to application. Affected files are lib/silcclient/client.c
167 and lib/silcclient/silcclient.h.
169 * Rewrote the text for Private Message Key Payload in the
170 protocol specification. Protocol TODO #11.
172 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
174 * Upgraded the protocol version to 1.1, updated protocol specs
177 * Added the nickname as new argument to NICK_CHANGE notify and

184 it to protocol specs and implemented it to client and server.
185 Protocol TODO #13. Affected files are silcd/command.c,
186 silcd/packet_receive.c, packet_send.[ch],
187 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
188 The killer's client entry is now returned to application in
189 the `notify' client operation.
191 * Fixed the Max Argument fields that had too large value set
192 in the protocol specs. Protocol TODO #14.
194 * Added the LEAVE command reply to return the ID of parted
195 channel. Updated protocol specs and implemented it to the
196 client and server. Protocol TODO #15. Affected files are
197 silcd/command.c, lib/silcclient/command_reply.c. The channel
198 entry is now returned to application in the `command_reply'
201 * Rewrote the version SKE version checking in client libary
202 and in server to use the silc_parse_version_string. Affected
203 files are lib/silcclient/protocol.c, silcd/protocol.c.
205 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
206 commands that was missing it, and updated protocol specs and
207 the server implementation. Protocol TODO #10. The affected
208 file is silcd/command.c.
210 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
211 generic reply to a generic request (REQUEST flag), and
212 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
213 way. A draft-riikonen-silc-flags-payloads-00.txt is written
214 to define the payload for DATA flag. Added the flags to
215 the implementation. Protocol TODO #9. Affected file is
216 lib/silccore/silcchannel.h.
218 Changed the client library to return the message length
219 to application as well in the channel_message and private_message
220 client operations. Affected files are
221 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
222 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
223 and lib/silcclient/client_ops_example.c.
225 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
226 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
227 the channel. Updated protocol specs and impelemented this
228 to client and server. Protocol TODO #6. Affected files are
229 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

232 Added new options m and M to CMODE command in Irssi SILC
233 client to set these modes.
235 * Deprecated all administrative commands from SILC protocol
236 since they are highly implementation specific commands.
237 Updated protocol specs. Moved the old commands in
238 implementations to private range of command types. Affected
239 files are silcd/command.c, lib/silcclient/command.c and
240 lib/silcclient/command_reply.c. Protocol TODO #8.
242 * Fixed a bug in server where sending unknown command crashes
243 the server. Affected file silcd/command.c.
245 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
247 * Added SILC_PROTOCOLVERSION macro to check protocol version
248 of a socket connection. The affected file is
249 lib/silcutil/silcsockconn.h.
251 * Added better error logging in rekey protocol. Affected file
254 * Do not check public key types in SKE during rekey. Affected
255 file lib/silcske/payload.c.
257 * Fixed the rekey protocol with PFS, which was totally broken.
258 Affected file silcd/protocol.c.
260 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Some client implementations quit network by doing first LEAVE
263 and then immediately SIGNOFF (like Bombyx). We now do check
264 after a short time after LEAVE notify and check whether the
265 client is still valid after LEAVE, and if not we remove it from
266 cache. Affected file is lib/silcclient/client_notify.c.
268 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
270 * Merged version 1.1.4 of zlib. Even if it not currently in use,
271 it's good not to have security holes here.
273 * Fixed a negative refcount situtuation for the config context.
274 Affected file is silcd/serverconfig.c.
276 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
278 * ROBOdoc documented lib/silcutil/silcutil.h.
280 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
282 * Optimized even more the SilcPacketContext structure. Now
283 totally saved 16 bytes of memory per context after optimization.
284 Affected files are lib/silccore/silcpacket.[ch].
286 * Made strict checks for valid SILC IDs. Affected file is
287 lib/silccore/silcid.c.
289 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

292 silc_hash_register, silc_hmac_register and silc_pkcs_register
293 to const. Affected files are lib/silccrypt/silccipher.[ch],
294 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
296 * Changed the silc_get_username and silc_get_real_name to
297 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
299 * Fixed the Irssi SILC Client to use the silc_get_username and
300 silc_get_real_name insted of glib routines since the glib
301 routines only corrupt stack. Fixes the Irssi SILC to work in
302 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
304 * Fixed the Irssi to not use g_get_home_dir since it crashes
305 or returns garbage on cygwin and corrupts stack. Added function
306 get_home_dir to Irssi routines. Affected files are
307 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
309 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
311 * Made some structure optimizations. SFTP memory FS MemFSEntry
312 entry structure. Optimized SilcTask structure. Optimized
313 SilcPacketContext structure.
315 Affected files lib/silcsftp/sftp_fs_memory.c,
316 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
318 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
320 * And yet again reverted back the config thing since Johnny
321 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
324 * Fixed memory leaks from config object. Affected files are
325 silcd/serverconfig.[ch].
327 * Added support for adding new connections to the server in rehash.
328 After rehash they take effect.
330 Added support for changing the maximum allowed connections in
331 rehash. The number can grow but going smaller is not supported.
333 Added function silc_server_num_sockets_by_remote to the
334 silcd/server_util.[ch].
336 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
338 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
340 * Added preliminary checking during config parsing for a valid
341 public/private key and removed further checks in the code.
342 Affected files are silcd/serverconfig.[ch], server.c.
344 * Moved functions silc_server_drop() and silc_server_daemonise()
345 from server.c to silcd.c since they are stricly related to
346 the application activity.
348 * Reverted a small part of the automatic ref/unref since
349 it caused a double unref in some situations. Affected
350 files are silcd/silcd.[ch], server.c, serverconfig.c.
352 * Added some .cvsignore files in the lib directory.
354 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
356 * Fixed silc_net_gethostbyaddr to correctly resolve by
357 address. Affected file lib/silcutil/silcnet.c.
359 * Fixed the notify relaying to client. The HMAC to be used
360 with relayed packets ws wrong and caused decryption failure
361 at the client end. Affected file is silcd/packet_receive.c.
363 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
365 * Created new branch silc_protocol_1_0_branch.
367 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
369 * Changed the silc_server_config_* routines to be SilcServer
370 independent. They are now officially application specific code
371 and not part of generic server implementation. Affected files
372 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
374 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
376 * Added automatic referencing of config context in the
377 silc_server_config_alloc, and automatic unreferencing in the
378 silc_server_config_destroy. Affected files are
379 silcd/serverconfig.[ch], silcd/silcd.c.
381 * Fixed the silc_log_quick handling in the logging routines.
382 It didn't log quickly when it was TRUE. Affected file is
383 lib/silcutil/silclog.c. Also the flush delay was set even
384 if it was 0 in config file. Affected file is
385 silcd/serverconfig.c.
387 * Added support for changing key pair of the server in rehash.
388 Affected file silcd/server.c.
390 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Fixed the TOPIC_SET notify to not cras. It changed the topic
393 too early, before getting the channel entry. Affected file
394 is silcd/packet_receive.c.
396 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
398 * Added functions silc_server_config_[ref/unref], these are used
399 to prevent that the config object is destroyed.
401 No longer directly affect global variables silc_log_quick and
402 silc_log_delay, they are first cached inside the config object
403 and then applied with silc_server_config_setlogfiles().
405 silc_server_config_set_defaults() is now internal to
406 serverconfig.c, there are no reasons to show this internal stuff
409 Affected files are silcd/serverconfig.[ch].
411 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
412 fprintf's to stderr, since some code may be executed again after
413 the server went into the background. Affected files are
416 * Added rehash support. Added function silc_server_rehash() that
417 will perform all the basic tasks of the rehashing procedure.
419 * Added command line option `-x, --hexdump'. This will enable the
420 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
421 The option `--hexdump' implies `--debug'.
423 * Fixed a bad bug in the logging APIs (silcutil library) where
424 the application would crash after calling silc_log_reset_all().
426 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
428 * Fixed the KICKED notify handling in client library to
429 correctly remove the channel and all entries from the
430 channel when I was kicked. This bug crashed the client.
432 Fixed yet another but in KICKED notify handling to remove
433 the kicked client correctly from the channel.
435 Affected file is lib/silcclient/client_notify.c.
437 * Fixed a minor bug in looking up correct client entry
438 in KICKED notify in server. Affected file is
439 silcd/packet_receive.c.
441 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
442 sources correctly to distribution. Fixes --with-gmp option.
444 * Removed the manual rehashing from ID Cache, and changed it
445 to use the SILC Hash Table's auto rehash feature. Affected
446 file is lib/silccore/silcidcache.c.
448 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
450 * Fixed a bug in the silc_client_nickname_format function that
451 handles the multiple same nickname formatting. Two clients
452 with same nickname caused problems after the first one left
453 and rejoined. It didn't format the nickname correctly.
454 Affected file is lib/silcclient/idlist.c.
456 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
458 * Don't change the topic if olod topic is same as new one.
459 Affected file is silcd/packet_receive.c.
461 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
463 * Added cross-reference support to the SILC Documentation
464 generator. All types across all HTML files are now cross-
465 referenced. Affected files util/robodoc/generator.c and
466 scripts/silcdoc/silcdoc.
468 * Added file lib/silcutil/silctypes.h to include all the
469 arithmetic type definitions and some macros. Removed
470 includes/bitmove.h and moved macros to silctypes.h.
472 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
474 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
476 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
478 * Added `type' argument to silc_id_payload_parse_id function which
479 now returns the type of the ID to the sent pointer. Affected
480 file is lib/silccore/silcid.[ch].
482 * Added check for CMODE_CHANGE notify type that mode change is
483 allowed by the sender. Affected file silcd/packet_receive.c.
485 * Added check for CUMODE_CHANGE notify type that mode change is
486 allowed by the sender. Affected file silcd/packet_receive.c.
487 Added the ID type as CUMODE_CHANGE notify type as argument
488 to the `notify' client operation. Affected files are
489 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
491 * Added function silc_client_add_server to the client library.
492 Added support for resolving also channel and server info when
493 received unknown entity in notify packet. Affected files are
494 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
496 * Added function silc_command_get_status to return the command
497 status from the command reply's argument payload. Affected files
498 are lib/silccore/silccommand.[ch].
500 * Added check for KICKED notify type that the kicking is
501 allowed by the client. Affected file silcd/packet_receive.c.
503 * Created function silc_get_input which can be used to get input
504 (echo on or off) from user on command line. Affected files are
505 lib/silcutil/silcutil.[ch].
507 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
509 * Optimized silc_server_packet_relay_to_channel function.
510 Added new function silc_channel_message_payload_encrypt which
511 can be called directly if channel message payload needs to
512 be encrypted and is already encoded (no need to call _encode
513 function). Packet relaying is now done by router without any
514 extra memory allocations. Affected files are
515 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
518 * Fixed the INVITE notify handling. It took wrong arguments

523 allowed by the client. Affected file silcd/packet_receive.c.
525 * Added check for INVITE notify type that inviting is allowed by
526 the client. Affected file silcd/packet_receive.c.
528 * Changed the silc_server_client_on_channel to return the
529 SilcChannelClientEntry as well. Moved the function
530 silc_server_check_cmode_rights to server_util.[ch].
531 Affected files are silcd/server_util.[ch], silcd/command.c.
533 * Added function silc_server_check_umode_rights to check whether
534 changing client's user mode is allowed. Added check for
535 UMODE_CHANGE notify type that the umode change is allowed
536 by the client. Affected files are silcd/server_util.[ch],
537 silcd/packet_receive.c and silcd/command.c.
539 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
542 ID length. It ignored that ID can be IPv6 based as well.
543 Affected file lib/silccore/silcpacket.h.
545 * Fixed the silc_id_id2str and silc_id_str2id to take the
546 IPv6 address offset's into consideration. Affecte file is
547 lib/silccore/silcid.c.
549 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Fixed the internal Unix scheduler functions to check for
552 NULL context they may receive. The affected file is
553 lib/silcutil/unix/silcunixschedule.c.
555 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
557 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
558 can specify different directory with --home command line
559 parameter. Affected files irssi/src/silc/core/client_ops.c,
562 * SILC-specific commands aren't now executed if the active server
563 isn't of SILC-type, so there won't be problems with having
564 IRC and SILC protocol support in same client. Affected files
565 irssi/src/silc/core/silc-channels.c, silc-servers.c,
568 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Improved the signal support in SILC Schedule. Added new
571 function silc_schedule_signal_call which is used by application
572 to mark a signal to be called. It is now safe to perform
573 any kind of tasks in signal callbacks since it is guaranteed
574 that the application specified signal callback is called
575 after the signal is over. Affected files are
576 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
578 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
580 * Added `name' field to SilcChannelPrivateKey to represent
581 application given name for the key. Moved also the context from
582 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
583 Added the `name' argument also to the function
584 silc_client_add_channel_private_key.
586 Added function silc_client_current_channel_private_key to set the
587 current channel private key in use.
589 Added "change" command to KEY command which can be used to change
590 the current channel private key. Bound the command also to
593 Also affected files lib/silcclient/client_channel.c,
594 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
596 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
598 * Added silc_rng_get_byte_fast function in to the
599 lib/silccrypt/silcrng.[ch].
601 * Changed the interface of silc_packet_assemble and the
602 silc_packet_send_prepare. If silc_packet_assmble is now
603 called the application does not call silc_packet_send_prepare
604 because the library will call it automatically. These
605 interfaces now also return a reference to the outgoing buffer
606 which includes the assembled packet, which the application can
607 use to encrypt the packet.
609 Affected files are lib/silccore/silcpacket.[ch],
610 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
611 silcd/packet_send.c, server_backup.c and packet_receive.c.
613 * Fixed a packet sending bug on very high load, where outgoing
614 packet queue wasn't handled correctly and packets got corrupted.
615 Affected files are lib/silcutil/*/silc*sockconn.c,
616 lib/silcclient/client.c and silcd/server.c.
618 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Added macro SILC_PACKET_DATALEN which can be used during
621 packet assembling to check whether the data to be added to
622 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
623 len is truncated until it fits it.
625 Added checks for maximum length of channel message payload and
626 private message payload also.
628 Added checks for maximum packet length in server and in
631 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
632 lib/silcclient/client.c, lib/silccore/silcchannel.c and
633 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
634 lib/silcclient/client_prvmsg.c.
636 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
638 * Added silc_server_packet_queue_purge call to the
639 silc_server_disconnect_remote to assure that all data in the
640 queue before disconnecting is sent to the network. Affected
643 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Added the deleting of server's own ID cache entry to the
646 silc_server_free function. Free also everything else that
647 has been allocated in silc_server_init. The affected file
650 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
652 * Added functions silc_parse_version_string, silc_version_to_num,
653 and silc_ske_parse_version to parse SILC protocol style version
654 strings. Affected files lib/silcutil/silcutil.[ch] and
655 lib/silcske/silcske.[ch].
657 * Added new configuration params: version_protocol, version_software
658 and version_software_vendor to specify what version the remote
659 host must at least be to be able to connect to server. The vendor
660 string can be regex matched too. Added new function
661 silc_server_connection_allowed to check maximum number of allowed
662 connections, and allowed versions for incoming connections.
663 Affected files are silcd/server.c, server_util.[ch] and
666 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
668 * Added preliminary support for signals in scheduler. The
669 signals we care about are now blocked always when the scheduler
670 is locked. This way we can synchronise the use of signal with
671 scheduler. It is guaranteed that when signal occurs the scheduler
672 is not locked, and thus new tasks can be safely added to the
675 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
676 to silc_schedule_internal_init and silc_schedule_internal_uninit.
677 Added new platform specific routines
678 silc_schedule_internal_signals_[un]block and
679 silc_schedule_internal_signal_[un]register.
681 Added new functions to SILC Schedule API:
682 silc_schedule_signal_[un]register. Each signal that application
683 is going to use should be registered to the scheduler.
685 Affected files are lib/silcutil/silcschedule.[ch],
686 lib/silcutil/*/silc*schedule.c.
688 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
690 * Check for unauthenticated client and server in the
691 silc_server_new_client and silc_server_new_server functions.
692 Affected file silcd/packet_receive.c.
694 * Added function silc_string_is_ascii to check whether given
695 string is 7-bit ASCII string. Affected files are
696 lib/silcutil/silcutil.[ch].
698 * Added function silc_id_is_valid_server_id into the
699 silcd/serverid.c and added checking for valid Server ID's in
700 silc_server_new_server. The Server ID must always be based
701 on the server's public IP address.
703 * Added logging of DISCONNECT packet message in the server.
704 Affected file silcd/server.c.
706 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Changed all library interfaces that use Global RNG to also
709 accept SilcRng as argument. Affected files are
710 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
711 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
712 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
713 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
716 * Added function silc_pkcs_generate_key to the
717 lib/silccrypt/silcpkcs.[ch] for applications so that they
718 don't need to do pkcs->pkcs->init calls anymore.
720 * Remove SilcSocketConnection from the SFTP API since it really
721 wasn't needed there. The application has the information
722 saved in its contexts anyway and the SFTP layer doesn't need
723 know about it. Affected files lib/silcsft/silcsftp.h and
724 lib/silcsftp/sftp_[server/client].c.
726 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
727 The SilcSimContext is not SilcSim.
729 * Fixed possible buffer overflows in silc_id_render in the
730 lib/silcutil/silcutil.c.
732 * On EPOC the global crypto module lists are not used at all
733 in the crypto library. Added support for using the constant
734 algorithm list on EPOC. Affected files are
735 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
738 * Fixed the handling of third parameter of KICKED notify, since
739 it was mistakenly updated to SILC Protocol 1.0 even though it
740 is to be included in 1.1. Since it is not in 1.0 it is not
741 mandatory, and this fix now handles it only if it is provided,
742 and it is not error if it is not provided. Affected file
743 lib/silcclient/client_notify.c.
745 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
747 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
748 client. Affected file irssi/src/silc/core/client_ops.c.
750 * Merged with Irssi 0.8.4 from irssi.org CVS.
752 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
754 * Check for valid socket connection in client entries before
755 sending any messages. Fixes a crash, but doesn't fix some
756 other underlaying bug that is lurking there. Affected
757 file silcd/packet_send.c.
759 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
761 * $usermode, $cumode and $cumode_space expandos shouldn't do
762 anything with non-SILC server records. Affected file
763 irssi/src/silc/core/silc-expandos.c
765 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
767 * Fixed the silc_net_check_[host/local]_by_sock to support
768 IPv6 bound sockets as well. Now they can return IPv6 addresses
769 as well. Affected file lib/silcutil/silcnet.c.
771 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
772 Affected lib/silcutil/unix/silcunixnet.c.
774 * Fixed ID rendering (at least on some platforms, not NetBSD)
775 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
777 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
779 * Added silc_hash_public_key and silc_hash_public_key_compare
780 functions to be used with SilcHashTable. They can be used to
781 hash public keys and compare public keys in hash table. Affected
782 file lib/silcutil/silcutil.[ch].
784 * Added support for specifying multiple public keys for Client
785 connection section in server configuration file. This makes it
786 possible to accept multiple public keys from same host, or to
787 make a section that accepts any incoming host, and have the
788 accepted public keys listed in the section.
790 Added functions silc_sever_[find/get]_public_key, added the
791 support for this actually to all connection sections but only
792 the Client section is currently allowed to specify multiple
795 Affected files are silcd/server.c, server_internal.h,
796 command.c, protocol.c, server_util.[ch], packet_receive.c.
798 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Merged Irssi 0.8.2 from irssi.org CVS.
802 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
804 * If silc_debug is TRUE, also output standard logging messages
805 to stderr with the debug output.
807 Made silc_log_reset_all() flushing all channels before returning.
808 Also fixed some documentation typos.
810 Affected files are lib/silcutil/silclog.[ch].
812 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
814 * Fixed the server to check correctly the amount of connections
815 from single host, by checking also the type of the connection.
816 Fixed also the comparison of number of connections and number
817 of allowed connections. Affected files are silcd/server.c,
820 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
822 * Fixed the USERS command reply to save the user's mode on the
823 channel as well. Fixed JOIN command reply to check whether a
824 client is on channel already and not join it twice. Affected
825 file lib/silcclient/command_reply.c.
827 * Added new file silc-expandos.c into irssi/silc/core/ to return
828 various stuff for various signal for the statusbar etc. updating.
829 Now Irssi SILC client prints channel user modes etc. on the
832 * The user mode (like server/router operator changes) is now shown
833 on the Irssi SILC client's statusbar. The affected files are
834 irssi/src/silc/core/client_ops.c, silc-expandos.c.
836 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
838 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
839 to SILC_SCHEDULE_[UN]LOCK macros.
841 * Added more error printing to logs in server code. Affected
842 files silcd/server.c and silcd/protocol.c.
844 * Fixed -S option parsing in Irssi SILC Client. Affected file
845 irssi/src/silc/core/silc-core.c.
847 * Added silc_buffer_alloc_size function. Affected file is
848 lib/silcutil/silcbuffer.h.
850 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
852 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
853 constants. Affected files in
854 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
857 * Changed the internal SFTP Memory FS table to const. Affected
858 file lib/silcsftp/sftp_fs_memory.c.
860 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
862 * Fixed the buffer formatting and unformatting routines to
863 check the size of 64 bits types with sizeof(). Affected
864 file is lib/silcutil/silcbuffmt.c.
866 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
868 * Removed 0.6.x backwards support.
870 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
872 * Changed all integer type names:
873 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
874 to avoid collisions with other libraries using same type names
877 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
879 * Added `prefer_ipv6' argument to the functions
880 silc_net_gethostbyname[_async]. If it is TRUE it will return
881 IPv6 address over IPv4. If FALSE IPv4 address is returned
882 even if IPv6 address was found. Affected files
883 lib/silcutil/silcnet.[ch].
885 * Added support silc_net_create_connection[_async] to fallback
886 to IPv4 address if IPv6 address could not be used (like if
887 it doesn't work on a specific system). Affected file in
888 lib/silcutil/unix/silcunixnet.c.
890 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
892 * Added silc_schedule_reinit function to do the enlarging
893 of the max tasks handling capabilities of the scheduler.
894 Affected files lib/silcutil/silcschedule.[ch].
896 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
898 * Added automatic extern "C" { ... } for C++ compilers so the
899 application does not need to define them. Affected file
900 includes/silcincludes.h.
902 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
903 old name went against naming convention. Applications now
904 include "silcclient.h" instead of "clientlibincludes.h".
905 Removed includes/clientlibincludes.h, it is redundant now.
907 * Renamed includes/version.h to silcversion.h.
909 * Added really preliminary support for OS/2 into the util
910 library. Only thread & mutex API is implemented, others
911 are still to be implemented. Created the lib/silcutil/os2/
912 directory. Created also file includes/silcos2.h.
914 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
916 * Added preliminary BeOS support into the util library.
917 Created lib/silcutil/beos/, and implemented all the needed
918 functions to support SILC on BeOS. Created also file
921 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
923 * Added proper initializations to silc's irssi code, so it's
924 now possible to load it as module. Affected files
925 irssi/src/silc/core/silc-core.c,
926 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
928 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
930 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
933 * Fixed the silcdoc document generator to correct generate
934 docs from all kinds of filenames. Affected files are
935 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
937 * ROBOdoc documented lib/silcutil/silcmemory.h.
938 Added also new function silc_memdup.
940 * Removed lib/silcutil/silcbufutil.h and moved those routines
941 to the lib/silcutil/silcbuffer.h.
943 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
945 * Added `user_count' to the SilcChannelEntry which now tells the
946 number of users on the channel. The user count is now saved
947 in normal server of global channels as well. Affected files
948 silcd/server.c, idlist.h, packet_receive.c and command.c.
950 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
951 include file utility functions.
953 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
954 instead of calling directly OS routines.
956 * Fixed NICK change printing in Irssi SILC Client. Fixed
957 KICKED notify printing in Irssi SILC Client. Affected file
958 irssi/src/silc/core/client_ops.c.
960 * Fixed a NICK change bug in client library, to not recreate the
961 client_entry->channels hash table everytime nick is changed.
962 Affected file lib/silcclient/client.c.
964 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
966 * ROBOdoc documented the lib/silcske/silcske.h, and improved
967 the SKE interface a bit.
969 * Fixed padding problem in PKCS#1. The padding was not actually
970 random since the random number generator was used incorrectly.
971 This security bug affects only when encrypting with PKCS#1, and
972 it is not currently used at all in SILC. SILC only use signing
973 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
975 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
977 * Rewrote the notify handling in Irssi SILC client to not call
978 the events as signals. Fixes problems with Perl support.
979 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
981 * Send the auto-nicking NICK command in client library with
982 little timeout after connecting. The affected file is
983 lib/silcclient/client.c.
985 * Added following new config file settings:
986 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
987 key_exchange_timeout, conn_auth_timeout, connections_max,
990 Implemented all the new config settings handling in the server.
992 Optimized the use of SKE Mutual flag usage. Use it only
993 if connection authentication protocol is not based in public
996 Renamed all SilcServerConfigSection* to SilcServerConfig*
997 to have a bit shorter names.
999 Affected files silcd/serverconfig.[ch], server.[ch], and
1002 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1004 * Cleaned up the listening sockets code, preparing for the rehash
1005 support. Affected file is silcd/server.c.
1007 * Fixed some output messages. Affected files are silcd/silcd.c,
1010 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1012 * Create lib/doc/silcrng_intro.html document as introduction
1013 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1015 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1017 * Fixes to the silcd config template. Affected file is
1018 doc/example_silcd.conf.in.
1020 * Removed type casts from silc_calloc(), conforming to the
1021 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1023 * Removed param_name member from client, server, and router
1024 section structs, now identifying the param directly.
1026 Added CONFIG_FREE_AUTH macro in config file parsing.
1028 Affected files are silcd/serverconfig.[ch].
1030 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1032 * Fixed command line parameter handling. All SILC initialization
1033 is now done in silc_core_init() which also fixes autoconnecting
1036 Affected files irssi/src/silc/core/silc-core.c,
1037 irssi/src/fe-text/silc.c.
1039 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1041 * Added new configuration options and blocks:
1042 keepalive_secs, reconnect_count, reconnect_interval,
1043 reconnect_interval_max, reconnect_keep_trying and
1044 require_reverser_lookup. Added ConnectionParam block, and
1045 implemented the connection parameters when connecting as
1046 initiator and when accepting connections as responder.
1048 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1049 whether given configuration value has been given already.
1051 Affected files silcd/serverconfig.[c], server.[c].
1053 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1054 algorithm parts and created new file silcalgs.conf, that
1055 is now included from the example_silcd.conf.in.
1057 * Optimized the silc_server_connect_to_router_second to take
1058 the connection configuration object from the SilcServerConnection
1059 object instead of finding it during the connecting phase.
1060 Added the configuration object to SilcServerConnection struct.
1061 Affected files silcd/server_internal.h, server.c.
1063 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1065 * Add the client on channel after it was resolved at the
1066 channel message receiving, and it was not already on the
1067 channel. Affected file lib/silcclient/client_channel.c.
1069 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1071 * Fixed the public key authentication to allocate always the

1077 * Unified the serverconfig.[ch]'s helper function interface.
1078 Affected file silcd/serverconfig.[ch].
1080 * Removed doc/example_silc.conf.in since it is redundant.
1081 The make install will now install irssi/silc.conf file.
1083 * Added new Passphrase and Publickey authentication methods to
1084 config file, allowing both public key and passphrase based
1085 authentication to be set at the same time.
1087 Added `prefer_passphrase_auth' setting in config file which
1088 can be used to set to prefer passwd auth if both passwd and
1089 public key is set. If not set, public key is preferred.
1090 This has effect only when being initiator (responder will try
1093 Added support for authentication with passphrase and public key
1094 at the same time. The passphrase is tried first always since
1095 it is faster to check.
1097 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1099 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1101 * Merged the new SILC Config library, with the server parsing
1102 support. Read the header file silcconfig.h or the toolkit
1103 documentation for the news. Affected files are

1112 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1114 * The silc_cipher_register, silc_hash_register and
1115 silc_hmac_register now checks if the object to be registered
1116 is registered already. Affected files are
1117 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1119 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1125 * Allow zero length channel messages inside the Channel Message
1126 Payload. Affected file lib/silccore/silcchannel.c.
1128 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1129 as header filenames.
1131 * Removed lib/silcclient/README and created HTML file
1132 lib/silcclient/silcclient_using.html, which is now included
1133 as part of Toolkit documentation.
1135 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1137 * Fixed CUMODE_CHANGE notify handling to change the mode of
1138 correct client. Affected file lib/silcclient/client_notify.c.
1140 * Make silc_rng_alloc fail if it cannot allocate the sha1
1141 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1143 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1145 * Fixed the file transfer's key agreement payload to include
1146 zero port also if the hostname is NULL because it could not
1149 Call file transfer monitor callback now also if error occurs
1150 during key agreement protocol.
1152 Changed the silc_client_file_send interface to return the
1153 SilcClientFileError instead of session id. The session ID
1154 is returned into pointer provided as argument.
1156 Check that the file exists locally before sending the
1157 file transfer request at all.
1159 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1161 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1162 error than can occur while key agreement protocol. Affected
1163 file lib/silcclient/silcapi.h.
1165 * Fixed the event_mode CMODE handler to not crash when mode
1166 is changed and +k mode is set in the channel. Affected file
1167 irssi/src/silc/core/silc-channels.c.
1169 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1170 SILC_LOG_WARNING to give out Warning and not Error. Affected
1171 file lib/silcutil/silclog.c.
1173 * Fixed the channel message payload decryption in the function
1174 silc_channel_message_payload_decrypt to not modify the original
1175 buffer before it is verified that the message decrypted
1176 correctly. Otherwise, next time it is called with correct
1177 channel key it won't encrypt since the payload is corrupted.
1178 Affected file lib/silccore/silcchannel.c.
1180 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1182 * Do not constantly resize the window. A fix patch by cras.

1190 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1192 * Fixed a bug in hash table internal routine for traversing
1193 the table with foreach callback. The current entry may
1194 become invalid in the callback but it was referenced after
1195 the callback returned.
1197 Do not allow auto rehashing of hash table during the
1198 silc_hash_table_foreach operation, for same reasons as it is
1199 not allowed for SilcHashTableList. Affected files are
1200 lib/silcutil/silchashtable.[ch].
1202 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1204 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1205 Win32 DLL. extern's in header files are now declared with
1208 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1210 * Fixed private message handling. It used some old code that
1211 caused the client to crash. Affecte file is
1212 lib/silcclient/client_prvmsg.c.
1214 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1216 * Added function silc_client_add_channel,
1217 silc_client_replace_channel_id, and removed functions
1218 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1219 from client library.
1221 * Added cross reference of the joined channels to the
1222 SilcClientEntry, and changed the SilcChannelEntry's
1223 users list to SilcHashTable. The affected files are
1224 lib/silcclient/idlist.[ch].
1226 * Fixed a bug in hash table tarversing. While the hash table
1227 is traversed with SilcHashTableList the table must not be
1228 rehashed. It is now guaranteed that auto rehashable tables
1229 are not rehashed while tarversing the list. Also defined that
1230 silc_hash_table_rehash must not be called while tarversing
1231 the table. Added function silc_hash_table_list_reset that must
1232 be called after the tarversing is over. The affected files are
1233 lib/silcutil/silchashtable.[ch].
1235 * Changed all hash table traversing to call the new
1236 silc_hash_table_list_reset in server and in client library.
1238 * Added function silc_client_on_channel to return the
1239 SilcChannelUser entry if the specified client entry is joined
1240 on the specified channel. This is exported to application as
1241 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1243 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1245 * Fixed founder regaining problem with JOIN command on normal
1246 server. The notify for mode change must be sent always and
1247 not only if !cmd->pending. Affected file silcd/command.c.
1249 * Fixed the WHOWAS command's reply sending to support the
1250 lists correctly. Affected file silcd/command.c.
1252 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * When sending JOIN command to router for processing the
1255 sender's old command identifier was not saved back to the
1256 sender's command context, fixed now. The affected file is
1259 * Create the key in JOIN command of the router did not return
1260 the channel key, added check for this. Affected file is
1263 * Fixed a channel ID update bug in JOIN command reply. Do
1264 not directly upgrade the ID but call the function
1265 silc_idlist_replace_channel_id if the ID was changed.
1266 Affected file silcd/command_reply.c.
1268 * Fixed memory leaks from command calling if it would fail.
1269 Affected file silcd/command.c.
1271 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1273 * Applied patches from cras:
1275 Memory leak fixes around libaries, irssi window resize fix,
1276 new silclist.h and silcdlist.h, all extern inline changed to
1279 * Removed dotconf from lib/dotconf, not needed anymore.
1281 * Removed TRQ from lib/trq, not needed anymore.
1283 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1284 with server connections. Later this will be configurable
1285 in config file after new config file is done. Affected file
1288 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1290 * Fixed a crash in server related to channel announcements.
1291 Affected file silcd/server.c.
1293 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1295 * Fixed memory leaks in silc_server_create_new_channel*
1296 functions. Affected file silcd/server.c.
1298 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1299 which ID was changed. This way the router will send the
1300 user list for the channel again, and server won't be in
1301 desync in some rare circumstances. Affected file is
1302 silcd/packet_receive.c.
1304 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Check for NULL socket pointer in the function
1307 silc_server_packet_send_to_channel_real. Affected file
1308 silcd/packet_send.c.

1311 list. Affected file silcd/packet_receive.c.
1313 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1315 * Fixed some header addition to Toolkit distribution in
1316 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1318 * Added lib/silcclient/client_ops_example.h as an template
1319 file for application programmers to quickly start using
1320 the SilcClientOperation functions in their application.
1321 Updated the lib/silcclient/README as well to tell about this
1322 nice file made available.
1324 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1326 * Call silc_server_remove_from_channels when removing client
1327 entry when NO_SUCH_CLIENT_ID was received. Affected file
1328 is silcd/command_reply.c.
1330 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1332 * Added server & router operator statistics updating. Affected
1333 file silcd/packet_receive.c and silcd/command.c.
1335 * Fixed the SERVER_SIGNOFF notify handling on normal server
1336 not to save the history information for clients. Same was
1337 fixed earlier in remove_clients_by_server function, but not
1338 here. Affected file silcd/packet_receive.c.
1340 * Raised the default connection-retry count from 4 to 7 in
1341 server. Affected file silcd/server.h.
1343 * Cancel any possible reconnect timeouts when we start the
1344 key exchange. Affected file silcd/server.c.
1346 * Do not reconnect on connection failure when SCONNECT was
1347 given. Affected files silcd/server.[ch].
1349 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1351 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1353 * Fixed the NICK command to always give the unformatted
1354 nickname to the one giving the NICK command. If unformatted
1355 nickname is cached already it will be formatted and the
1356 local entry will always get the unformatted nickname.
1357 Affected file lib/silcclient/idlist.c.
1359 * Fixed some double frees from client library commands.
1360 Affected file is lib/silcclient/command.c.
1362 * Fixed CUMODE command in server to assure that no one can
1363 change founder's mode than the founder itself, there was a
1364 little bug. Affected file silcd/command.c.
1366 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1368 * Removed the SilcClientCommandDestructor from the client
1369 libary, it is not needed anymore. Affected files are
1370 lib/silcclient/silcapi.h, command[_reply].[ch],
1371 client_notify, idlist.c.
1373 * Fixed GETKEY command to first resolve client, and then
1374 resolve the server only if the client was not found, instead
1375 of resolving both at the same time. Affected file is
1376 lib/silcclient/command.c.
1378 * Added silc_client_start_key_exchange_cb and lookup the
1379 remote hostname and IP address before starting the key
1380 exchange with server. The affected file is
1381 lib/silcclient/client.c.
1383 * The server's public key is now saved using the IP address
1384 of the server and not the servername for the filename.
1385 The hostname public key filename is checked as an fall back
1386 method if the IP address based filename is not found.
1388 Fixed the GETKEY command to save the fetched server key
1389 in correct filename.
1391 Print the remote server's hostname now when new key is
1392 received during connection process. Affected file is
1393 irssi/src/silc/core/client_ops.c.
1395 * Return always our own public key to the client if it asks
1396 for it with GETKEY command. Affected file silcd/command.c.
1398 * Removed the use_auto_addr variable from default config
1399 file since it was in wrong section. Affected file is
1402 * Fixed TOPIC_CHANGE notification to not route it when it
1403 was sent using silc_server_send_notify_to_channel function.
1404 Affected file silcd/command.c.
1406 * Fixed silc_server_send_notify_kicked to send the kicker's
1407 Client ID also, it was missing. Affected files are
1408 silcd/command.c, silcd/packet_send.[ch].
1410 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1412 * Do not save client history information in SERVER_SIGNOFF.
1413 Fixes the bug in normal server that it does not detect
1414 the client becoming valid after the server becomes back
1415 online. Affected file silcd/server_util.c.
1417 * Added `sock_error' field into the SilcSocketConnection
1418 context. When error occurs during socket operation (read
1419 or write) the error is saved. Added also new function
1420 silc_socket_get_error to return human readable socket error
1421 message. Affected files are lib/silcutil/silcsockconn.[ch],
1422 lib/silcutil/unix/silcunixsockconn.c, and
1423 lib/silcutil/win32/silcwin32sockconn.c.
1425 * The server now prints the socket error message in the
1426 signoff for client. Affected file silcd/server.c.
1428 * Fixed the `created' channel information sending from router
1429 to server in JOIN command. Checks now whether the channel
1430 really was created or not and set it according that.
1432 Fixed the JOIN command to use the client entry's current
1433 ID during the joining procedure instead of the one it sent
1434 in the command (it is checked though), since it can change
1435 between the packet processing and command processing, and
1436 would just case unnecessary pain in the client end. Affected
1437 file silcd/command.c.
1439 * Fixed a channel key payload sending to use correct channel
1440 ID when the server was forced to change the channel's ID by
1441 router. Router sent the key payload with the old Channel ID.
1442 Affected file silcd/packet_receive.c.
1444 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1446 * Call silc_server_save_channel_key only if the key payload
1447 was provided in the JOIN command's command reply. Affected
1448 file silcd/command_reply.c.
1450 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1452 * Fixed silc_mp_sizeinbase to return the value correctly with
1453 MPI. Affected file lib/silcmath/mp_mpi.c.
1455 * Fixed the stop_server signal to correctly stop the scheduler
1456 and gracefully stop the server when SIGTERM or SIGINT signals
1457 are received. Affected file silcd/silcd.c.
1459 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1461 * Simple handling of TERM and HUP signals. Also added some log
1462 flushing call around. Affected file is
1465 * Fixed small bugs in silclog.c. Now buffering output will take
1466 effect after 10 seconds since startup: This will ensure that
1467 no important startup messages are lost. Also output redirection
1468 will preserve original format ([Date] [Type] message).
1469 Affected file is lib/silcutil/silclog.c.
1471 * Added two options to the config file, in the logging section:
1472 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1473 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1475 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1477 * Do not print the warning about log files not being initialized
1478 more than once to avoid excess logging. Affected file is
1479 lib/silcutil/silclog.c.
1481 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1482 the SIM copying in make install in Makefile.am.pre.
1484 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1486 * Rewritten silclog APIs. Globally interesting changes follows:
1487 silc_log_set_files() changed to silc_log_set_file().
1488 silc_log_set_callbacks() changed to silc_log_set_callback().
1489 ROBOdoc documented silclog header file.
1490 SilcLogCb now returns bool to wether inihibit the default
1491 handler or not (to keep the old behaviour return always TRUE).
1492 The new APIs should also fix the problem of the
1493 silcd_error.log file that was written in the current directory.
1496 Log files streams will remain opened after silc_log_set_file()
1497 call, means less CPU usage notably on high traffic servers.
1498 File streams are now full buffered, and flushed to the disk
1499 every 5 minutes, lesses HD activity and CPU usage.
1500 Messages can be redirected, allowing admins to configure
1501 one single logfile for all server messages.
1502 the silc_log_quick global variable to activate fast-logging.
1503 Affected files lib/silcutil/silclog.[ch]
1505 * Changed some code to conform new silclog APIs. Affected
1506 files are doc/example_silcd.conf.in, silcd/server.c
1507 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1510 * Fixed a memory leak that could occur in some situations.
1511 Affected file silcd/serverconfig.c.
1513 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1515 * Added the silc_client_del_client to remove the client from
1516 all channels as well. Affected file lib/silcclient/idlist.c.
1518 * Fixed the client library to correctly remove the client
1519 from all channels when the client entry is being destroyed.
1520 Affected file lib/silcclient/client_notify.c, command.c.
1522 * Added auto-nicking support to the client library. If the
1523 applicatio now sets client->nickname it will be sent to the
1524 server after connecting by the library. This way for example
1525 SILCNICK (or IRCNICK) environment variables will have effect
1526 and always change the nickname automatically to whatever
1527 it is wanted. Affected file lib/silcclient/client.[ch].
1529 * Renamed silc_server_command_bad_chars to the
1530 silc_server_name_bad_chars and moved it to the
1531 silcd/server_util.[ch]. Added also new function
1532 silc_server_name_modify_bad to return nickname that
1533 includes bad characters as new nickname without those
1534 bad characters. This check and modify is now used in
1535 silc_server_new_client when the username is initially set
1536 as nickname, so it must be checked to be valid nickname.
1537 Affected file silcd/packet_receive.c.
1539 * The nickname length is now taken from the packet for real
1540 and not trusted to strlen() since it clearly can return
1541 wrong length for nickname including bad characters. This
1542 also applies to channel names. Affected file silcd/command.c.
1544 * Removed the lib/silcsilm/modules directory. Modules are now
1545 compiled into the lib/silcsim. Fixed the copying of the
1546 modules to follow symbolic links in Makefile.am.pre.
1548 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1550 * Fixed silc_string_regexify list creation. Fixes bugs with
1551 BAN and INVITE commands in server. The affected file is
1552 lib/silcutil/unix/silcunixutil.c.
1554 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Removed the command destructor entirely from the server's
1557 command and command reply routines. It is not needed, and
1558 its usage was buggy and caused crashes. Affected files are
1559 silcd/command[_reply].[ch].
1561 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Cancel protocol and NULL sock->protocol if timeout
1564 occurred during protocol. Affected file silcd/server.c.
1566 * Cancel protocol timeouts always before calling the final
1567 callback, to assure that after final callback is called
1568 no other state will be called for the protocol anymore.
1569 Affected file silcd/protocol.c.
1571 * Print error log if incoming connection configuration could
1572 not be found. Affected file silcd/server.c.
1574 * Fixed JOIN command to correctly save the founder mode
1575 to the client on normal SILC server, when the channel
1576 was created by the router. Affected file silcd/command.c.
1578 * Fixed LIST command (hopefully) to send correct reply
1579 packets. Affected file silcd/command.c.
1581 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * The silc_packet_receive_process now returns FALSE if the
1584 read data was invalid packet, and TRUE if it was ok.
1586 The server now checks that if unauthenticated connection
1587 sends data and its processing fails the server will close
1588 the connection since it could be a malicious flooder.
1590 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1592 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1594 * Make sure the warning about error opening a log file is
1595 printed only once and not everytime it fails (produces
1596 too much useless log). Affected file lib/silcutil/silclog.c.
1598 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1600 * Made the silc_server_daemonise() function more readable.
1601 Affected file silcd/server.c.
1603 * Pid file is now optional, the user may comment it out from
1604 the config file. Removed define SILC_SERVER_PID_FILE, we
1605 don't need a default any longer. Affected file
1606 configure.in.pre, lib/Makefile.am.pre.
1608 * Make some use of the pid file. The server now dies at startup
1609 if it detects a valid pid file on his path. The server would
1610 die anyway in this circumstance, because of the bind() failure.
1611 Affected file silcd/silcd.c.
1613 * No longer compiling lib/dotconf.
1615 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Fixed JOIN command parsing not to crash. Affected file
1618 lib/silcclient/command.c.
1620 * Fied the NICK_CHANGE notify to add the new client entry
1621 even it is resolved. This removes an <[unknown]> nick
1622 thingy bug in the client. Affected file is
1623 lib/silcclient/client_notify.c.
1625 * Do not try to allocate 0 bytes (efence does not like it)
1626 in lib/silccore/silccomand.c when encoding payload.
1628 * Do not take IRCNICK as nickname in Irssi SILC client since
1629 it is not possible to set nickname before hand connecting
1630 the server (TODO has an entry about adding auto-nicking
1633 * Changed the silc_server_command_pending to check whether
1634 there already exists an pending entry with the specified
1635 command, command identifier and pending callback. This is
1636 to fix IDENTIFY and WHOIS related crashes that may register
1637 multiple pending commands with same identifier. Affected
1638 file silcd/command.c.
1640 * Fixed the server to reconnect to the router even if it
1641 was already reconnecting and EOF was received. This to
1642 fix a possibility that the server wouldn't ever try to
1643 auto-reconnect to the router. Affected file silcd/server.c.
1645 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Fixed the server's password authentication to use the
1648 length of the locally saved password, and not the one
1649 sent in the packet. Affected file silcd/protocol.c.
1651 * Fixed same password authentication problem in the
1652 Authentication Payload handling routines in
1653 lib/silccore/silcauth.c.
1655 * Yet another password authentication problem fixed with
1656 channel password handling in silcd/command.c.
1658 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * If first character of string in silc_parse_userfqdn is '@'
1661 then do not parse it. Affected file is
1662 lib/silcutil/silcutil.c.
1664 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * Fixed minor bug in IDENTIFY command reply sending, which
1667 caused various weird problems during JOIN when it was
1668 resolving names for users. Affected file silcd/command.c.
1670 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1672 * Fixed the IDENTIFY command reply sending to chech better valid
1673 clients. It was possible to send incomplete list of replies.
1674 Affected file silcd/command.c.
1676 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Added silc_client_command[s]_[un]register functions now to
1679 dynamically register the commands in client library. Removed
1680 the static table of commands. This allows the client library
1681 to call commands without causing the application to know about
1682 what commands library has called.
1684 Removed the INFO command reply kludge to detect when the command
1685 was called by library. Now library use its own command reply
1686 function for INFO command.
1688 Added function silc_client_command_call to call a command.
1689 Application can use it to call command, not access the structure
1692 Now all commands that are sent by the client library (not
1693 explicitly sent by application) use own command reply functions.
1695 Affected files around lib/silcclient/ and in
1696 irssi/src/silc/core/.
1698 * Fixed the WHOIS command reply sending to chech better valid
1699 clients. It was possible to send incomplete list of replies.
1701 Fixed the WHOIS and IDENTIFY to send the request to router
1702 if normal server did not do it and did not find any results.
1704 Affected file silcd/command.c.
1706 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Moved the internal data from SilcClient context into its
1709 own file, not accesible to application. Affected files
1710 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1711 and other files in client library.
1713 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Added doc/examples installation target in Makefile.am.pre.
1718 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1721 commands the found client entry will be removed from the
1722 cache, after notifying application about the error. Affected
1723 file lib/silcclient/command_reply.c.
1725 * Changed the /MSG to check for exact nickname user gave, and
1726 not let `nick' match `nick@host' if it is only one found. Now,
1727 user must type the exact nickname (like nick@host2) even if
1728 there are no more than one same nicks found. This is to avoid
1729 a possibility of sending nickname to wrong nickname since
1730 `nick' could match `nick@host'. Affected file is
1731 irssi/src/core/silc-servers.c.
1733 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Do not print "you are now server operator" or similar when
1736 giving /away command. Affected files are
1737 irssi/src/silc/core/client_ops.c, silc-servers.h.
1739 * Made the silc_server_command_pending_error_check to send
1740 the same command reply payload it received back to the
1741 original sender of the command. This way all arguments
1742 that was received by the server will be received by the
1743 client too. Affected file silcd/command.c.
1745 * Added the silc_idcache_add to return the created cache entry
1746 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1748 * Add global clients to expire if they are not on any channel.
1749 This is because normal server will never know if they signoff
1750 if they are not on any channel. The cache expiry will take
1751 case of these entries. This is done by normal servers only.
1752 The affected files are silcd/command_reply.c,
1753 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1755 * If server receives invalid ID notification for WHOIS or
1756 IDENTIFY and the ID exists in the lists, it is removed.
1757 Affected file silcd/command_reply.c.
1759 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1760 in client then client entry that it matches is searched and
1761 the nickname is printed on the screen for user. Affected
1762 file irssi/src/silc/core/client_ops.c.
1764 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Use cache entry expire time in the LIST command reply to
1767 purge old entries from the cache after the LIST command
1768 reply has been received. This way we don't have non-existent
1769 entries in the cache for too long. Affected file is
1770 silcd/command_reply.c.
1772 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * If we are normal server, and we've not resolved client info
1775 in WHOIS or IDENTIFY from router, and it is global client,
1776 we'll check whether it is on some channel. If it is not
1777 then we cannot be sure about its validity and will resolve it
1778 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1779 file silcd/command.c.
1781 * Search channel by name (if possible) rather than by ID
1782 in IDENTIFY command's command reply. Affected file is
1783 silcd/command_reply.c.
1785 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1787 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1788 Updated specs and implemented it. Affected file silcd/command.c,
1789 silcd/packet_send.c and silcd/packet_receive.c.
1791 * Implemented the <founder auth> payload handling in the JOIN
1792 command. If provided all conditions for channel joining
1793 except requirement to provide correct passphrase can be
1794 overrided by the channel founder. Updated the protocol specs.
1795 Affected file silcd/command.c.
1797 Added support for founder auth in JOIN command in client
1798 library. Fixed the parsing of the JOIN command now to support
1799 all options as they should be. The affected file is
1800 lib/silcclient/command.c.
1802 * Optimized the WHOIS and IDENTIFY commands to send the request
1803 to router only if it includes nicknames or other names. If
1804 they include only IDs then check the local cache first before
1805 routing. Affected file is silcd/command.c.
1807 * Added channels topic announcements. Affected file is
1808 silcd/packet_receive.c and silcd/server.c.
1810 * Fixed the silc_server_send_notify_topic_set to really destine
1811 the packet to channel. Affected file silcd/packet_send.c.
1813 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1814 library. Affected file lib/silcclient/client_notify.c.
1816 * Added UMODE announcements. Affected file silcd/server.c.
1818 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Memory leak fixes in:
1822 lib/silcutil/silcsockconn.c
1823 lib/silcske/silcske.c
1824 lib/silcske/groups.c
1826 lib/silccrypt/silcpkcs.c
1827 lib/silccore/silccommand.c
1828 lib/silccore/silcidcache.c
1833 * ROBOdoc documented the lib/silcske/groups.h file and a
1834 bit changed the interface for better.
1836 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1838 * Update the client entry context in the ID cache after
1839 nick change. Affected file lib/silcclient/command.c.
1840 Fixes the CUMODE command when regaining founder privileges,
1841 and a little WHOIS problem.
1843 * Fixed silc_net_gethostbyname to correctly call the
1844 inet_ntop. Affected file lib/silcutil/silcnet.c.
1846 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1848 * Added IPv6 support checking to the configure.in.pre, added
1849 also --enable-ipv6 option to override the check. Affected
1850 file configure.in.pre.
1852 * The silc_thread_create now calls the start function
1853 directly if threads support is not compiled in. Removes
1854 ugly #ifdef's from generic code. Affected files are
1855 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1857 * Added silc_net_gethostby[name/addr]_async to asynchronously
1858 resolve. Affected files are lib/silcutil/silcnet.[ch].
1860 * Added support for rendering IPv6 based server, client and
1861 channel IDs. Affected file lib/silcutil/silcutil.c.
1863 * Added support for creating IPv6 based server IDs. Affected
1864 file is silcd/serverid.c.
1866 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1868 * Added silc_net_gethostby[addr/name] into the
1869 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1870 routines. Added silc_net_is_ip[4/6]. Affected file is
1871 lib/silcutil/unix/silcunixnet.c. All routines that take
1872 address as argument now supports both IPv4 and IPv6 addresses.
1874 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1876 * Fixed LIST command reply sending in server. Affected file
1879 * Server now sends the kicker's client ID in the KICK notify
1880 to the kicked client. Affected file silcd/command.c.
1882 * The client library now parses the kickers client ID and
1883 UI displays it. Affected files lib/silcclient/client_notify.c
1884 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1886 * Made all payload parsing function prototypes consistent.
1887 They all take now const unsigned char * and uint32 pair as
1888 the payload data instead of SilcBuffer. Changes all around
1889 the source tree. Other unsigned char* -> const unsigned char*
1890 changes around the tree as well.
1892 * Optimized SFTP client and server packet sending not to
1893 allocate new buffer for each packet but to recycle the
1894 first allocated buffer. Affected files are
1895 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1897 * Optimized the SFTP client to use SilcList instead of
1898 SilcDList for requests, because it is faster. Affected file
1899 is lib/silcsftp/sftp_client.c.
1901 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1902 into lib/silccore/silcid.[ch].
1904 Renamed silcpayload.[ch] into silcargument.[ch].
1906 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * If client entry is deleted with active key agreement
1909 session, abort the session.
1911 The silc_client_abort_key_agreement now calls the completion
1912 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1914 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1917 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Don't use __restrict in older GCC's. Affected file is
1920 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1922 * silc_net_localhost now attempts to reverse lookup the
1923 IP/hostname. Affected file lib/silcutil/silcnet.c.
1925 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1926 command. It can be used to gain founder privileges at
1927 the same time when joining the channel.
1929 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1930 kicker's client ID as well. Updated protocol specs.
1932 Defined that the server must send SILC_COMMAND_IDENTIFY
1933 command reply with error status to client who sent
1934 private message with invalid client ID.
1936 Updated the protocol specification.
1938 * Added silc_server_send_command_reply to send any
1939 command reply. Affected file silcd/packet_send.[ch].
1941 * Added silc_id_payload_encode_data to encode ID payload
1942 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1944 * The server now send IDENTIFY command reply with error
1945 status if client ID in private message is invalid. Affected
1946 file silcd/packet_receive.c.
1948 * Save the server key file with server's IP address in
1949 the filename instead of hostname. The affected file is
1950 irssi/src/silc/core/client_ops.c.
1952 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1957 * Added libtool support for compiling shared objects in
1958 lib/silcsim. Affected file configure.in.pre and
1959 lib/silcsim/Makefile.am. Original patch by cras.
1961 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Pid file configuration, and server's config file fixes
1964 patch by toma. Updated CREDITS file.
1966 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Fixed silc_client_channel_message to not try to decrypt
1969 the message twice if it resolved the destination client
1970 information. This could cause of dropping one channel
1971 message. Affected file lib/silcclient/client_channel.c.
1973 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1976 lib/silcclient/client.c. This function is used when the SILC
1977 Client is run under some other scheduler, or event loop or
1978 main loop. On GUI applications, for example this may be
1979 desired to used to run the client under the GUI application's
1980 main loop. Typically the GUI application would register an
1981 idle task that calls this function multiple times in a second
1982 to quickly process the SILC specific data.
1984 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1986 * Fixed silc_server_drop() for dropping the supplementary
1987 groups as well, this could cause a security hole on some
1990 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1992 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

1996 to run server on foreground. A patch by debolaz.
1997 Affected files silcd/server.c, silcd/silcd.c.
1999 * Fixed MOTD to return the MOTD file server name. Affected
2000 file silcd/command.c.
2002 * Added INFO command reply handling to the Irssi SILC Client.
2003 Affected file irssi/src/silc/core/client_ops.c.
2005 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Fixed the silc_idcache_list_* routines to really support
2008 the dynamic list. Fixes a crash. Affected file is
2009 lib/silccore/silcidcache.c.
2011 * Fixed the LIST command reply to really call LIST command's
2012 pending callbacks. Affected file silcd/command_reply.c.
2014 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Update conn->local_entry->nickname after giving NICK
2017 command. Affected file lib/silcclient/command.c.
2019 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2021 * Added the [pid] option to the silcd configuration file
2023 Affected files: serverconfig.[ch] and silcd.c
2025 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Save fingerprint in WHOIS command reply in server.
2028 Affected file silcd/command_reply.c.
2030 * Fixed NICK commands pending callback registration.
2031 Affected file lib/silcclient/command.c.
2033 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Use ++server->cmd_ident when sending commands in server,
2036 instead of random number. Affected file silcd/command.c.
2038 * Fixed GETKEY command reply to call actually GETKEY pending
2039 command callbacks. Affected file silcd/command_reply.c.
2041 * A bit stricter check for nicknames. Check for same nickname
2042 in NICK command also. Affected file silcd/command.c.
2044 * Do not call INFO command everytime client ID changes, only
2045 during first connecting. Affected file lib/silcclient/client.c.
2047 * Set the new nickname only after successful command reply for
2048 NICK command is returned by server. Affected file
2049 lib/silcclient/command.c.
2051 * Remove nicknames from nicklist during server_signoff notify.
2052 Should fix /NAMES bit more. The affected file is
2053 irssi/src/silc/core/silc-channels.c.
2055 * Added `fingerprint' field to the SilcIDListData in the
2056 silcd/idlist.h to hold the fingerprint of the client's
2059 Send the fingerprint of the client's public key in WHOIS
2062 Affected files silcd/command.c, and silcd/idlist.[ch].
2064 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2065 create fingerprint from given data.
2067 * Show the fingerprint of the client's public key in WHOIS.
2068 Affected files irssi/src/module-formats.[ch] and
2069 irssi/src/silc/core/client_ops.c.
2071 * Format the multiple same nicknames also during JOIN and
2072 NICK_CHANGE notifys. Affected file is
2073 lib/silcclient/client_notify.c.
2075 * Do not print error on screen for invalid private message
2076 payload since it can come if someone is sending private
2077 messages with wrong key. Affected file
2078 lib/silccore/silcprivate.c.
2080 * Fixed multiple concurrent /PING crash. Affected file
2081 lib/silcclient/command.c.
2083 * Changed the wrong ID encoding. All IP addresses must be
2084 in MSB first order in encoded format. They were encoded
2085 wrong and was in LSB format. Affected files are
2086 silcd/serverid.c, lib/silcutil/silcutil.c.
2088 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2090 * Call the `connect' client operation through the scheduler
2091 in case of error. Affected file lib/silcclient/client.c.
2093 * Call the `failure' client operation even if the error
2094 occurred locally during a protocol. Affected file is
2095 lib/silcclient/protocol.c.
2097 * Added support of sending LIST command to router from normal
2098 server. This way normal server can get list of all channels
2099 in the network too. Fixed the channel list sending in the
2100 server too. Affected files are silcd/command.c, and
2101 silcd/command_reply.[ch].
2103 * Added silc_server_update_channels_by_server and
2104 silc_server_remove_channels_by_server. They are used during
2105 disconnection of primary router and in backup router protocol.
2106 Affected file silcd/server_util.[ch], silcd/server.c and
2107 silcd/server_backup.c.
2109 * Fixed channel adding to global list in IDENTIFY command
2110 reply in server. Affected file silcd/command_reply.c.

2114 * If the incoming packet type is REKEY or REKEY_DONE process
2115 that packet always synchronously. Fixes yet another MAC
2116 failed error on slow (dialup) connections. Affected file
2117 lib/silcclient/client.c and silcd/server.c.
2119 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Call check_version SKE callback for initiator too. Affected
2122 file lib/silcske/silcske.c.
2124 * Implemented fix for security hole found in the SKE that was
2125 fixed in the specification few days back; the initiator's
2126 public key is now added to the HASH value computation.
2127 Added backwards support for the old way of doing it too, for
2128 old clients and old servers. Affected file is
2129 lib/silcske/silcske.c.
2131 * Enabled mutual authentication by default in SKE. If initiator
2132 is not providing mutual authentication the responder will
2133 force it. This will provide the proof of posession of the
2134 private key for responder. The affected files are
2135 lib/silcclient/protocol.c and silcd/protocol.c.
2137 * Do not cache anymore the server's public key during SKE.
2138 We do mutual authentication so the proof of posession of
2139 private key is done, and if the server is authenticated in
2140 conn auth protocol with public key we must have the public
2141 key already. Affected file silcd/protocol.c.
2143 * Added new global debug variable: silc_debug_hexdump. If
2144 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2145 file lib/silcutil/silclog.[ch].
2147 * Fixed compilation warning due to char * -> const char *.
2148 Affected files lib/silcutil/silcnet.h, and
2149 lib/silccore/silcauth.[ch].
2151 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Fixed CMODE command when new channel key was created. If
2154 the creation failed the old key was removed. Next time giving
2155 same command would crash the server since the old key was
2156 freed already. Affected file silcd/command.c.
2158 * Fixed the silc_server_announce_get_channels to not crash
2159 on reconnect. Affected file silcd/server.c.
2161 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Added silc_log_set_debug_string function to set a regex
2164 string to match for debug output. Only the function names,
2165 or filenames matching the given debug string is actually
2166 printed. This way it is possible to filter out those debug
2167 strings that user is not interested in.
2169 Fixed a bug in silc_string_regexify.
2171 Affected files lib/silcutil/silclog.[ch], and
2172 lib/silcutil/unix/silcunixutil.c.
2174 * Changed the -d options in both server and Irssi SILC client
2175 to take the debug string as argument. Affected files
2176 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2178 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Added silc_hash_babbleprint to create a Bubble Babble
2181 Encoded fingerprint. The encoding is developed by Antti
2182 Huima (draft-huima-babble-01.txt), and it creates human
2183 readable strings out of binary data. Affected file
2184 lib/silccrypt/silchash.[ch].
2186 * Print the babble print now in addition of fingerprint as well
2187 in Irssi SILC client. Affected files are
2188 irssi/src/fe-common/silc/module-formats.[ch],
2189 irssi/src/fe-common/silc/core/client_ops.c.
2191 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * Fixed a security problem found in SKE. The initiator's
2194 public key too is now added to the HASH hash value creation
2195 which is signed by the responder to create the SIGN value.
2196 This will prevent anyone in the middle to lie to the responder
2197 about the initiator's public key. If this is done now, the
2198 man in the middle will get caught. Updated the protocol
2201 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Better installation directory handling. Configure module
2204 paths and other paths automatically to example_silc* files
2205 in doc/. A patch by toma.
2207 * Fixed compiler warning from MPI library, and from SILC RNG.
2210 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2211 It can be configured with ./configure. A patch by toma.
2213 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Find correct make to use in prepare-clean. A patch by
2216 toma. Affected file prepare-clean.
2218 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2220 * Added irssi variables use_auto_addr, auto_bind_ip,
2221 auto_bind_port and auto_public_ip.
2223 * Changed the interface for silc_client_send_key_agreement
2224 in lib/silcclient/silcapi.h
2228 irssi/src/silc/core/silc-core.c
2230 lib/silcclient/silcapi.h
2231 irssi/src/silc/core/silc-channels.c
2232 lib/silcclient/client_keyagr.c
2235 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Added silc_pkcs_public_key_compare to compare two
2238 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2240 * Check that the client who set the founder mode on the
2241 channel is the same client that is giving the founder
2242 mode to itself. It is done by comparing the saved public
2243 key (it is saved even in the authentication is passphrase).
2244 Affected file silcd/command.c.
2246 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Do not process packet for disconnected socket connection.
2249 Affected file lib/silccore/silcpacket.c.
2251 * Process the DISCONNECT packet through scheduler in the
2252 client library. Affected file lib/silcclient/client.c.
2254 * Fixed the silc_client_packet_parse to not to increase
2255 the packet sequence number if the conn->sock and the
2256 current socket connection is not same. This can happen
2257 for example during key agreement when the conn includes
2258 multiple socket connections (listeners). Affected file
2259 lib/silcclient/client.c.
2261 * The sender of the file transfer request now provides also
2262 the pointer (listener) for the key exchange protocol. If
2263 the listener cannot be created then it sends empty key
2264 agreement and lets the receiver provide the listener.
2266 Added `local_ip' and `local_port' arguments to the
2267 silc_client_file_send. If they are provided they are used,
2268 if not then it will attempt to find local IP address, if
2269 not found or bind fails then the remote client will provide
2272 Affected files are lib/silcclient/client_ftp.c and
2273 lib/silcclient/silcapi.h.
2275 * Extended the FILE SEND command to support defining the
2276 local IP and port for key exchange listener. They are
2277 optional. Affected file irssi/src/silc/core/silc-servers.c.
2279 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Defined to WHOIS command reply the sending of fingerprint
2282 of the client's public key (if the proof of posession of the
2283 corresponding private key is verified by the server).
2284 Updated to the protocol specification.
2286 * Added support of receiving the client's public key's
2287 fingerprint in command reply in client library. Affected
2288 file is lib/silcclient/command_reply.c, and
2289 lib/silcclient/idlist.[ch].
2291 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Do not send over 128 chars long nickname to the server
2294 in NICK command. Affected file lib/silcclient/command.c.
2296 * Do not send over 256 chars long channel names to the server
2297 in JOIN command. Affected file lib/silcclient/command.c.
2299 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Assure that silc_server_close_connection cannot be called
2302 twice for same socket context. Affected file is
2305 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Send error message to application if opening file for
2308 writing during file transfer fails. Affected file is
2309 lib/silcclient/client_ftp.c.
2311 Remove all file transfer sessions for a client that we're
2312 removing from ID cache.
2314 Affected file is lib/silcclient/client_ftp.c.
2316 * Fixed silc_net_addr2bin to return correct address. Affected
2317 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2319 * Fixed file transfer session removing on signoff notify.
2320 Affected file irssi/src/silc/core/silc-servers.c.
2322 * Added the SilcClientFileError to be returned in the monitor
2323 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2324 Affected file lib/silcclient/silcapi.h.
2326 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Fixed a crash in silc_client_ftp_free_sessions and
2329 silc_client_ftp_session_free_client. Affected file
2330 lib/silcclient/client_ftp.c.
2332 * Added `disabled' field in the SilcChannelEntry in the server
2333 to indicate if the server entry is disabled. Affected file
2334 silcd/idlist.h, silcd/command[_reply].c.
2336 * SILC server adds now /var/run/silcd.pid everytime it is
2337 started. Affected file silcd/silcd.c.
2339 * Added silc_server_packet_send_clients to send a packet to
2340 the provided table of client entries. Affected file
2341 silcd/packet_send.[ch].
2343 * Fixed a crash in client resolving in client_prvmsg.c in
2344 client library. Affected file lib/silcclient/client_prvmsg.c.
2346 * Do not actually remove the client directly from ID cache
2347 during SERVER_SIGNOFF, but invalidate it. This way we
2348 preserve the WHOWAS info for the client. Affected file
2349 silcd/server_util.c.
2351 * Fixed SERVER_SIGNOFF notify handling in the server. The
2352 server is now able to process incoming SERVER_SIGNOFF notify
2353 for a server that it doesn't even know about. It will remove
2354 the clients provided in the notify. Affected file
2355 silcd/packet_receive.c.
2357 * Check for partial packet in data queue after every packet that
2358 was found from the queue. Return and wait for more data if
2359 there is partial data in queue. Affected file is
2360 lib/silccore/silcpacket.c.
2362 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Added SilcClietFileError enum to indicate error in
2365 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2366 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2367 Affected files lib/silcclient/silcapi.h and
2368 lib/silcclient/client_ftp.c.
2370 * Check that newsize in silc_buffer_realloc is larger than
2371 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2373 * Added better monitor of file transfers. It now monitors
2374 key agreement protocol during the file transfer too. Added
2375 error reporting too. Affected files
2376 irssi/src/silc/core/silc-servers.c,
2377 irssi/src/fe-common/silc/module-formats.[ch].
2379 * Wrote a help file for FILE command.
2381 * Added silc_rng_global_get_byte_fast to get not-so-secure
2382 random data as fast as possible. Random data is read from
2383 /dev/urandom if available and from the SILC RNG if not
2384 available. It is used in padding generation. Affected file
2385 lib/silccrypt/silcrng.[ch].
2387 * All packets in client library are now processed synchronously.
2388 Optimized packet processing a lot. Affected file
2389 lib/silcclient/client.c.
2391 * All server connection packets are processing synchronously
2392 now in server, to optimize packet processing. Affected file
2395 * Include files are installed now only in Toolkit distribution
2396 if make install is given. Affected files: all Makefile.am's.
2398 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Assure that silc_client_notify_by_server_resolve does not
2401 resolve the client information multiple times. If it cannot
2402 be found by the first it cannot be found at all. Affected
2403 file lib/silcclient/client_notify.c.
2405 * Fixed WHOWAS command reply calling. Affected file
2406 lib/silcclient/command_reply.c.
2408 * Removed all references to silc_idlist_get_client from the
2409 Irssi SILC client since that call is internal call used by
2410 the library. The Irssi SILC client will use now client
2411 retrieval functions found in silcapi.h.
2413 * Fixed a bug in resolving nickname info before sending
2414 private message. It used freed memory. Affected file
2415 irssi/src/silc/core/silc-servers.c.
2417 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Assure my_channels statistics cannot go negative in server.
2420 Affected files silcd/server.c, silcd/server_util.c.
2422 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2426 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

2436 * Added silc_net_localip to return local host's IP address.
2437 Affected file lib/silcutil/silcnet.[ch].
2439 * If key exchange or rekey protocol is active for a connection
2440 parse all packets syncronously since there might be packets
2441 in packet queue that we are not able to process without first
2442 processing packets before them. Affected file silcd/server,
2443 lib/silcclient/client.c.
2445 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2446 whether library should continue processing the packet.
2447 Affected file lib/silccore/silcpacket.h.
2449 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2450 SilcSFTPMonitorData to SFTP server to monitor various
2451 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2452 lib/silcsftp/sftp_server.c.
2454 * Added silc_file_size to return file size. Affected file
2455 lib/silcutil/silcutil.[ch].
2457 * Implemented the file transfer support for the client library.
2458 Added preliminary support for simple client to client one-file
2459 transmission. Affected file lib/silcclient/client_ftp.c,
2460 lib/silccilent/client.[ch].
2462 * Added new local command FILE to the Irssi SILC Client.
2463 It is used to perform the file transfer. It has subcommands
2464 SEND, RECEIVE, SHOW and CLOSE. Affected files
2465 irssi/src/silc/core/client_ops.c,
2466 irssi/src/silc/core/silc-server.[ch].

2475 * Renamed silc_file_read and silc_file_write to functions
2476 silc_file_readfile and silc_file_writefile. Added function
2477 silc_file_open and silc_file_close. Affected files
2478 lib/silcutil/silcutil.[ch].
2480 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Resolve the client info when received private message or
2483 channel message for a client which nickname we don't know.
2484 Affected files lib/silcclient/client_prvmsg.c and
2485 lib/silcclient/client_channel.c.
2487 * Do not crash in /KEY if client is not connected. Affected
2488 file irssi/src/silc/core/silc-channels.c.
2490 * Added SilcClientStatus field to the SilcClientEntry in the
2491 lib/silcclient/idlist.h.
2493 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2494 is incomplete and is being resolved, it won't be resolved
2497 Make sure also that USERS command reply does not resolve
2498 twice information. Affected file is
2499 lib/silcclient/command_reply.c.
2501 Make sure that silc_client_get_clients_by_list does not
2502 resolve twice same information.
2504 * Check for valid client->id in the silc_server_free_client_data.
2505 Affected file silcd/server.c.
2507 * Fixed /GETKEY nick@server not to crash if the server entry
2508 is not found. Affected file lib/silcclient/command.c.
2510 * Fixed the silc_server_check_cmode_rights to check the
2511 requested modes correctly. Affected file silcd/command.c.
2513 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Better checks for non-printable chars in nick added.
2516 Affected file silcd/command.c.
2518 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Call the silc_server_udpate_servers_by_server in the
2521 primary router that comes back online in the backup resuming
2522 protocol. Otherwise it routes packets wrong. Affected file
2523 silcd/server_util.[ch], silcd/server_backup.c.
2525 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2528 lib/silcutil/silcbuffmt.[ch].
2530 * Redefined the SILC packet header to include the padding
2531 length. Affected file lib/silccore/silcpacket.[ch].
2533 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2534 length for maximum padding up to 128 bytes). Affected
2535 file lib/silccore/silcpacket.h.
2537 * Removed all backwards support for old 0.5.x MAC thingies.
2538 The SILC packet header change makes it impossible to be
2539 backwards compatible.
2541 * Send the ENDING packet with timeout in the backup resuming
2542 protocol. This is to assure that all routers has connected
2543 to the primary router. Affected file silcd/server_backup.c.
2545 * Changed the RNG to take the first IV from random data. It
2546 used to take it from zero actually. Changed the RNG also
2547 to use /dev/urandom during session. /dev/random is used
2548 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2550 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Changed the SILC packet header to have the first two bytes
2553 (the packet length) encrypted. Affected files aroung the
2554 code tree, lib/silccore/silcpacket.[ch]. Removed the
2555 SilcPacketCheckDecrypt callback. It is not needed anymore
2556 since the silc_packet_receive_process will determine now
2557 whether the packet is normal or special.
2559 * Implemented the unidirectional MAC keys. Affected files
2560 lib/silcske/silcske.c, silcd/protocol.c and
2561 lib/silcclient/protocol.c.
2563 * Implemented the packet sequence number to the MAC computation.
2564 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2565 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2566 lib/silcclient/protocol.c.
2568 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Allow backup router to announce servers. All servers
2571 announced by backup router are added to the global list
2572 automatically. Update hte server's socket to our primary
2573 router also when backup router announces a server.
2574 Affected file silcd/packet_receive.c.
2576 * Do not update the client->router in the function
2577 silc_server_udpate_clients_by_server if the client is on
2578 global list. We might fail to find any specific server
2579 for locally connected clients and local cell clients. They
2580 should still use the `from' and not `to' as client->router.
2581 This fixes backup router resuming protocol. Affected file
2582 silcd/server_util.c.
2584 * Decrease channel statistics count only if the channel
2585 deletion worked. Affected files are silcd/server.c and
2586 silcd/server_util.c.
2588 * Added silc_server_update_servers_by_server to update origin
2589 of all server entries. Used during backup router protocol.
2590 Affected files silcd/server_util.[ch], silcd/server.c. and
2591 silcd/backup_router.c.
2593 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2594 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2595 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2596 lib/silccrypt/silchmac.c.
2598 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Assure that router cannot reroute the same channel message
2601 to the sender. Affected file silcd/packet_receive.c.
2603 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Made better checks that the channel message is not sent
2606 to the router it came from. Affected file is
2607 silcd/packet_send.c. Fixed memory leak too.
2609 * Announce informations for incoming router connection, but
2610 only after checking if it is replaced by backup router.
2611 Affected file silcd/packet_receive.c.
2613 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Fixed the backup resuming protocol to work in multiple
2616 router environment. Affected file silcd/server_backup.c.
2618 * Route packet only to one router in the function
2619 silc_server_packet_send_to_channel. Affected file is
2620 silcd/packet_send.c.
2622 * Fixed silc_server_send_notify_dest to set the broadcast
2623 flag. Fixed the silc_server_send_notify_topic to actually
2624 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2625 Affected file silcd/packet_send.c.
2627 * Changed the SFTP Filesystem interface. Changed the
2628 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2629 the filesystem operation function. The SilcSFTPFilesystem
2630 is now a context that is allocated by all filesystem allocation
2631 functions and it already includes the operations structure
2632 and filesystem specific context. It is given as argument
2633 now to the silc_sftp_server_start. This made the interface
2634 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2635 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2637 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Changed the backup router adding and getting interfaces
2640 in the server. The router that will be replaced by the
2641 specified backup router is now sent as argument. Affected
2642 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2645 * Added silc_net_addr2bin_ne to return the binary form of
2646 the IP address in network byte order. Affected files
2647 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2649 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2651 * Check for existing server ID in silc_server_new_server
2652 and in silc_server_connect_to_router_final and remove the
2653 old entry if it exists. Affected file silcd/packet_receive.c,
2656 * Send the channel message always to only one router, either
2657 in upstream or downstream. Affected file is
2658 silcd/packet_send.c.
2660 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Wrote the definition of the backup resuming protocol to the
2663 protocol specification.
2665 * Removed one redundant channel key generation from normal
2666 server during joining procedure. Removed one redundant
2667 channel key sending from server to router during joining
2668 procedure. Affected file silcd/command.c.
2670 * Made minor bugfixes to the backup router resuming protocol.
2671 Affected file silcd/server_backup.c, server.c.
2673 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * Added --disable-asm configuration option. Affected files
2676 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2679 * Implemented the backup resuming protocol that is used to
2680 resume the primary router position in the cell after the
2681 primary router comes back online. Affected files
2682 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2683 and silcd/server_util.[ch].
2685 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Sleep two (2) seconds after sending QUIT command to server.
2688 Affected file lib/silcclient/command.c.
2690 * Assure that if outgoing data buffer is pending do not force
2691 send any data. Affected file silcd/packet_send.c.
2693 * Assure that if outgoing data buffer is pending do not force
2694 send any data. Affected file lib/silcclient/client.c.
2696 * Implemented the backup router support when the primary router
2697 goes down. The servers and routers can now use the backup
2698 router as new primary router without loosing connectivity.
2700 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2703 in the server to indicate disabled entry. All data read
2704 from the connection will be ignored and no data is sent
2705 for entry that is disabled. Affected files are
2706 silcd/idlist.h, silcd/server.c.
2708 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Created SFTP client and server test programs in the
2711 lib/silcsftp/tests directory.
2713 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Implemented memory filesystem (virtual filesystem) for
2716 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2719 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2721 * Implemented the SFTP (SSH File Transfer Protocol) to the
2722 lib/silcsftp. It includes SFTP client and SFTP server
2725 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2727 * Moved lib/silccore/silcprotocol.[ch] to the
2728 lib/silcutil library.
2730 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2731 take variable argument list pointer as argument. Affected
2732 file lib/silcutil/silcbuffmt.[ch].
2734 * Added silc_buffer_set function that is used to set data
2735 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2736 Affected file lib/silcutil/silcbuffer.h.
2738 * Changed various routines in the core library to use the new
2739 silc_buffer_set instead of allocating new buffer only for
2742 * Added 64-bit value formatting and unformatting support to the
2743 silc_buffer_[un]format routines. Affected file is
2744 lib/silcutil/silcbuffmt.[ch].
2746 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2747 to includes/bitmove.h.
2749 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Fixed channel user mode saving in client library. Affected
2752 file lib/silcclient/command[_reply].c.
2754 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Defined the file transfer to the SILC Protocol. Added
2757 new packet type SILC_PACKET_FTP and defined File Transfer
2758 Payload. The mandatory file transfer protocol is SFTP
2759 (SSH File Transfer Protocol). Affected file in addition
2760 of the internet draft is lib/silccore/silcpacket.h.
2762 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2763 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2764 is used as part of backup router protocol when the primary
2765 router of the cell is back online and wishes to resume
2766 the position as primary router.
2768 * Redefined the MAC generation keys in the protocol. The
2769 same key is not used anymore in both direction. Both
2770 direction will now use different keys for sending and
2771 receiving. This fixes a potential security flaw. This
2772 change causes incompatibilities in the protocol.
2774 * Redefined also the MAC computation from the packet.
2775 An packet sequence number is now added to the MAC
2776 computation. This prevents possible replay attacks against
2777 the protocol. This change too causes incompatibilities
2780 Added `sequence' field to the SilcPacketContext to hold
2781 the current sequence number for the packet.
2783 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Added `created' field to the SilcIDListData in the file
2786 silcd/idlist.h to indicate the time when the entry was
2789 * Added `created' field to the SilcChannelEntry too. Affected
2790 file silcd/idlist.h.
2792 * Added `creation_time' aguments to all the announcement functions
2793 in the server. If it is provided then only the entries that
2794 was created after the provided time frame are actually
2795 announced. Affected file silcd/server.[ch].
2797 * The protocol says that the Channel ID's IP address must be
2798 based on the router's IP address. Added check for this in
2799 the silc_server_new_channel when processing incoming New Channel
2800 Payload. Affected file silcd/packet_receive.c.
2802 * Print out the correct version with --version in SILC client.
2803 Affected file irssi/src/silc/core/silc-core.c.
2805 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Fixed WHOWAS command to check for completnes of the client
2808 entry always, not just when the command is coming from client.
2809 Affected file silcd/command.c.
2811 * Added new function silc_server_packet_queue_purge to purge the
2812 outgoing data queue to the network. After the function returns
2813 it is guaranteed that the outgoing packet queue is empty.
2814 Affected file silcd/packet_send.[ch].
2816 * Purge the outgoing packet queue in the rekey protocol's final
2817 callback to assure that all rekey packets go to the network
2818 before quitting the protocol. Affected file silcd/server.c.
2820 * Added silc_client_packet_queue_parse as similar function as
2821 in server to the client library. The affected file is
2822 lib/silcclient/client.c.
2824 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Splitted silcd/server.c and created silcd/server_util.[ch]
2827 for utility functions.
2829 * Added new socket flag SILC_SF_DISABLED to indicate that the
2830 connection is open but nothing can be sent to or received from
2831 the connection. Affected file lib/silcutil/silsockconn.[ch].
2832 The checking for disabled socket is checked in the low level
2833 silc_socket_write and silc_socket_read functions.
2835 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Allow only nicknames and channel names that fits into the
2838 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2840 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * When processing JOIN command reply in server check that if
2843 the channel exists in our global list we'll move it the local
2844 list. Affected file silcd/command_reply.c.
2846 * Fixed the check whether client is joined on the channel already
2847 in JOIN command. Affected file lib/silcclient/command.c.
2849 * Fixed the JOIN command reply to check whether the channel
2850 already exists. Affected file lib/silcclient/command_reply.c.
2852 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Added silc_ske_status_string to map the SKE error numbers
2855 to readable strings. The affected files are
2856 lib/silcske/silcske[_status].[ch].
2858 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Do not show the private channels on the WHOIS channel list
2861 as it is not allowed by the protocol. The affected file is
2864 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Assure that the packet length digged from the actual packet
2867 is something sensible in the silc_packet_decrypt_rest_special
2868 in lib/silccrypt/silcpacket.c.
2870 * Free and NULL the allocated pointer in silc_hmac_alloc if
2871 the HMAC allocation fails. The affected file is
2872 lib/silccrypt/silchmac.c.
2874 * Print the selected security properties to the log files in
2875 the server. Affected file silcd/protocol.c.
2877 * Add SKE's reference counter even if calling the completion
2878 callback manually. Otherwise it goes negative, although it
2879 does not cause any problems. The affected file is
2880 lib/silcske/silcske.c.
2882 * Remove the client entry with short timeout after giving the
2883 KILL command. Affected file lib/silcclient/command.c.
2885 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2886 case all found clients are already disconnected (WHOWAS would
2887 found them) in the server. Affected file silcd/command.c.
2889 * Update the last_receive (time of last data received) to be
2890 updated only when received private or channel message so that
2891 the idle time showed in WHOIS makes more sense.
2893 * Added boolean field `valid' in to the SilcClientEntry in the
2894 client library to indicate whether the entry is valid or not.
2895 This fixes the nickname change bug on channel when changing
2896 the nickname to be same than the old (like nick to Nick) the
2897 nickname formatter doesn't set the new nick anymore to Nick@host.
2898 Affected file lib/silcclient/idlist.[ch].
2900 * Now actually fixed the nickname changing on disconnection.
2901 Added new function silc_change_nick to the Irssi SILC Client.
2902 Affected file irssi/src/silc/core/client_ops.c,
2903 irssi/src/silc/core/silc-nicklist.[ch].
2905 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Check that the public key exists in the GETKEY command before
2908 trying to encode it. Affected file silcd/command.c.
2910 * Print some notifications on received public keys with GETKEY
2911 command in the Irssi SILC Client. Affected files are
2912 irssi/src/fe-common/silc/module-formats.[ch],
2913 irssi/src/silc/core/client_ops.c.
2915 * Use IDENTIFY command to resolve the server information in the
2916 GETKEY command instead of INFO command. Affected file
2917 lib/silcclient/command.c.
2919 * All command reply functions in the client library now calls
2920 the pending command reply callbacks even if an error has
2921 occurred. The server has done this a long time and now it was
2922 time to move the client library to this as well. Now all
2923 errors can be delivered back to the pending command reply
2924 callbacks if necessary. Affected files are
2925 lib/silcclient/command[_reply].[ch].
2927 * Change the nickname on disconnection back to the username
2928 because in reconnect the server will enforce it to it anyway.
2929 Affected file irssi/src/silc/core/silc-servers.c.
2931 * Fixed a config file parsing bug in the Irssi SILC client.
2932 Affected file irssi/src/silc/core/clientconfig.c.
2934 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2936 * When printing the channel mode on JOIN, verify that the
2937 channel key and channel's HMAC are valid. Affected file
2938 irssi/src/silc/core/client_ops.c.
2940 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2943 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2944 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2946 * Removed channel key rekey task deleting from the function
2947 silc_server_save_channel_key. Affected file silcd/server.c.
2948 Added explicit timeout task context instead that is used to
2949 delete the task if we are registering a new task before the
2950 new task has elapsed.
2952 * When channel key rekey occurs the client library now saves
2953 the old channel key for a short period of time (10 seconds) and
2954 is able to use it in case some is still sending channel
2955 messages encrypted with the old key after the rekey. Affected
2956 file lib/silcclient/[idlist.h|client_channel.c].
2958 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Added check to the silc_server_new_id_real to not accept
2961 new ID if it is the sender's own ID. Affected file is
2962 silcd/packet_receive.c.
2964 * Assure that we do not announce ourself or the one we've
2965 sending our announcements when we're router and are announcing
2966 servers to our primary router. Affected file silcd/server.c.
2968 * Fixed silc_server_command_identify_check_client to assemble
2969 correct WHOIS packet. It send corrupted WHOIS packet and
2970 caused problem with router to router connections. Affected
2971 file silcd/command.c.
2973 Fixed also silc_server_command_whois_check the same way
2974 as for the IDENTIFY command.
2976 * Added new SilcIDListStatus to the server in the SilcIDListData
2977 structure. The status now includes the current status of
2978 the entry (like registered, resolved etc.). Affected file
2979 silcd/idlist.[ch]. Defined a bunch of different status types
2980 as well. This replaced the old boolean registered field as well.
2982 Added resolve_cmd_ident field to the SilcClientEntry structure
2983 too so that if the entry is for example being resolved so
2984 another command may attach to the same pending command reply
2985 without requiring to resolve the same entry again. This concept
2986 should optimize the WHOIS and the IDENTIFY resolving under
2987 heavy load by taking away unnecessary resolving for entries
2988 that are being resolved already.
2990 Added support for adding multiple pending commands for one
2991 command idenfier. Affected file silcd/command[_reply].[ch].
2993 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2994 before deleting the data. Otherwise the hash table will have
2995 freed data in comparison functions. Affected file is
2996 silcd/command_reply.c.
2998 * Fixed silc_idlist_replace_client_id to add the new entry to
2999 the cache with NULL nickname. Otherwise there will be invalid
3000 memory as the nickname after the nickname is freed. Affected
3001 file silcd/packet_receive.c.
3003 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3004 saved into wrong slots because the previous number of entries
3005 was not taken into account. Affected file silcd/idlist.c.
3006 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3008 * If we are router and we receive JOIN notify to a channel that
3009 does not have any users then notified client is marked as the
3010 channel founder, as it is it. The affected file is
3011 silcd/packet_receive.c
3013 * Added to the extended hash table API's table_del_*ext functions
3014 the destructor as argument too, so that the caller can decide
3015 which destructor to use or whether to use destructor at all.
3016 Affected file lib/silcutil/silchashtable.[ch].
3018 * Fixed ID Cache purging. It actually deleted the entries from
3019 the hash table after the data was freed. The hash table ended
3020 up comparing freed memory. The affected file is
3021 lib/silccore/silcidcache.c.
3023 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Fixed Irssi SILC client's KILL command's HELP syntax.
3027 * The USERS command now resolves the detailed user information
3028 if the userinfo field is missing. Affected file is
3029 lib/silcclient/command_reply.c.
3031 * Do not print error in silc_file_read if the read file does
3032 not exist. Just silently return NULL. Affected file is
3033 lib/silcutil/silcutil.c.
3035 * Fixed the silc_log_output to not wine about NULL filename
3036 and to not create some bogus " " filename. Affected file is
3037 lib/silcutil/silclog.c.
3039 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Fixed various printing bugs on the user interface in the
3042 Irssi SILC Client. Minor changes that were forgotten from
3045 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Fixed the configure.in.pre and the compilation and distribution
3048 environment to support the new autoconf 2.52. That version is
3049 now required to compile the CVS trunk.
3051 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3054 to generally parse user@fqdn format strings. Affected file
3055 lib/silcutil/silcutil.c.
3057 * Added nickname_format and nickname_force_format fields to the
3058 SilcClientParams structure. The first one defines the format
3059 for the nicknames that the library will enforce if the receives
3060 multiple same nicknames. The second one is boolean value and
3061 can be used to force the library to always enforce the format
3062 to the nicknames regardles whether there are multiple nicknames
3063 or not. This configurable formatting was employed to flexibly
3064 support accessing multiple nicknames from the user interface.
3065 The userinterface can now set the nicknames to what ever format
3066 they prefer. Affected file lib/silcclient/silcapi.h.
3068 Added function silc_client_nickname_format to the file
3069 lib/silcclient/idlist.c. It performs the nickname formatting.
3071 Added new field `hostname´ to the SilcClientEntry context.
3072 It holds the hostname of the client. Affected file is
3073 lib/silcclient/idlist.h.
3075 * Irssi SILC Client sets the nicknames in nick@hostn format.
3076 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3077 irssi/src/silc/core/silc-core.c.
3079 The WHOIS printing now also shows both the real nickname and
3080 the formatted nickname so that user knows how to access the
3081 user if there are multiple same nicknames cached. Affected
3082 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3083 printing formatting too to take the hostname now as a separate
3084 argument. The Affected file is
3085 irssi/src/fe-common/silc/modules-formats.[ch].
3087 * Changed the silc_client_get_clients_local to accept the formatted
3088 nickname as argument. It accepts the real nickname too but the
3089 formatted nickname can be used to find the true entry from
3090 multiple entries. Affected file lib/silcclient/silcapi.h and
3091 lib/silcclient/idlist.c.
3093 * Added nickname_format_parse field to the SilcClientParams.
3094 It is a callback function provided by the application to parse
3095 the nickname out of the formatted nickname string. The library
3096 calls it to get the nickname from the formatted string. Since
3097 the application generally knows better the format of the nickname
3098 string it parses it instead of the library, even though library
3099 encodes the formatted string. If the callback function is not
3100 provided then the library will use the string as is. The
3101 affected file is lib/silcclient/silcapi.h.
3103 * All the nickname strings passed to the client library in
3104 commands are now expected to be formatted nickname strings.
3105 If the command does not support the formatted nickname string
3106 it will assume that the sent string is the actual nickname.
3107 Affected file lib/silcclient/command.c.
3109 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Added public key authentication support to OPER and SILCOPER
3112 commands in the client library. Affected file is
3113 lib/silcclient/command.c.
3115 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Changed the get_auth_methdod client operation to be asynchronous.
3118 It can be async if the application resolves the authentication
3119 method from the server during the negotiation. Added new
3120 SilcGetAuthMeth completion callback that the application will
3121 call after resolving the authentication method.
3123 Added function silc_client_request_authentication_method that
3124 the application can use to resolve the authentication method
3125 from the server. Added also SilcConnectionAuthRequest callback
3126 that the library will call after the server has replied. The
3127 application can call this function if it does not know the
3128 current authentication method.
3130 Affected files are lib/silcclient/client.c and
3131 lib/silcclient/silcapi.h.
3133 * The Irssi SILC client now automatically resolves the authentication
3134 method incase any configuration information is not present (and
3135 currently there never is). The affected file is
3136 irssi/src/silc/core/client_ops.c.
3138 * Fixed public key authentication from the client library.
3139 Affected file lib/silcclient/protocol.c. Changed also the
3140 protocol specification about the public key authentication in
3141 the connection authentication protocol. The actual data to be
3142 signed is now computed with a hash function before signing.
3144 * Fixed the public key authentication from the server as well.
3145 Affected file silcd/protocol.c.
3147 * Removed the mlock()'s from the memory allocation routines.
3148 Affected file lib/silcutil/silcmemory.c. The ./configure does
3149 not check anymore for the mlock(). Affected file is
3152 * Fixed USERS command in server to allow the execution of the
3153 command for private and secret channels if the client sending
3154 the command is on the channel. Affected file silcd/command.c.
3156 * Fixed silc_client_get_clients_local to return the clients
3157 count correctly. It could return wrong value. Affected file
3158 lib/silcclient/idlist.c.
3160 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3162 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3163 types. The assembler optimizations seemed not to like 64-bit
3164 data types. The assmebler optimizations thus are now enabled
3165 also for BSD systems as opposed to only enable them for Linux.
3167 * Do not check for threads at all on BSD systems. Affected
3168 file configure.in.pre.
3170 * Removed -n and -h options from the Irssi SILC Client since
3171 they are not used in silc.
3173 * Fixed the prime generation to assure that the first digit
3174 of the generated random number is not zero since our conversion
3175 routines does not like number strings that starts with zero
3176 digit. If zero digit is seen the random number is regenerated.
3177 This caused some corrupted RSA keys when the zero first digit
3178 was met. Affected file lib/silcmath/silcprimegen.c.
3180 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Fixed WIN32 configuration in the ./configure script.
3183 Fixed to include xti.h on environments that has it.
3184 Patches by Carsten Ilchmann and andrew.
3186 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Changed the silc_id_create_client_id to be collision
3189 resistant. It is now assured that there cannot be created
3190 two same client ID's. I suspect that some weird bugs in
3191 the server were actually caused by duplicate Client IDs.
3192 Affected file silcd/serverid.[ch]. A router receiving
3193 new ID now also assures and informs the sending server
3194 if the ID caused collision.
3196 * Changed the silc_id_create_channel_id to also assure that
3197 there are no collisions.
3199 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3201 * Statement about ignoring the Mutual Authentication flag when
3202 performing rekey with PFS was a bit misleading. It is ignored
3203 if it was set in the initial negotiation, it cannot be even
3204 set in the rekey. Fixed in the ke-auth draft. Started the
3205 new versions of the protocol drafts in the doc/.
3207 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * Fixed a bug in silc_client_command_identify_save when saving
3210 new channel information. The channel name was no duplicated
3211 and caused crash on exit. Affected file is
3212 lib/silcclient/command_reply.c.
3214 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3216 * Fixed the getkey command handling in the server. Send just
3217 empty OK reply to the sender if the key could not be fetched
3218 (but everything else was ok, like the key just was not available).
3219 Changed the public key parameter to optional in the protocol
3220 specs so that empty OK reply can be sent. Affected file
3223 Added a message to Irssi SILC client to tell to user if the
3224 server did not return a public key.
3226 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3228 * Fixed a channel key regeneration bug. It registered new
3229 timeout tasks exponentially until all system resources were
3230 used. Affected file silcd/server.c.
3232 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3234 * Added the SILC Document generator to the scripts/silcdoc.
3235 It can be used to generate the Toolkit Reference Manual out
3236 of the source tree. Internally it will also use the RoboDoc
3237 generator now imported in util/robodoc.
3239 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Added couple of return's in rekey protocol if error orccurred
3242 during the protocol. The execution must be terminated.
3243 Affected file silcd/protocol.c. Also, terminate the protocol
3244 always with timeout.
3246 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * The client's Client ID was created initally from the wrong
3249 nickname (it could have been in format nick@host) in the
3250 silc_server_new_client. Affected file silcd/packet_receive.c
3252 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Added some SILC_LOG_ERROR's to various error conditions
3255 if client could not be added to ID cache. Affected files
3256 silcd/packet_receive.c and silcd/server.c.
3258 * When client's sock->user_data is freed, NULL also the
3259 client->router and client->connection pointers. Added check
3260 for these pointers being NULL to various places around the
3261 code. Affected file silcd/server.c.
3263 * Added client->data.registered == TRUE checks to various
3264 places around the code to assure that unregistered client's
3265 are not handled when it is not allowed. Affected file
3268 * Added `bool registered' fields to all
3269 silc_idlist_[server|client]_get_* routines to indicate whether
3270 the fetched client needs to be registered or not. Affected
3271 file silcd/idlist.[ch].
3273 * Add your own entry as registered to the ID cache in the
3274 server. Affected file server.c.
3276 * Fixed a bug in silc_server_new_server. The SilcServer was
3277 set as the new server's context instead of SilcServerEntry.
3278 This naturally caused some weird bugs.
3280 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Do not delete the channel rekey task when adding it
3283 for in silc_server_create_channel_key.
3285 * Changed the silc_server_create_channel_key to return
3286 TRUE or FALSE to indicate the success of the channel key
3289 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Fixed MSVC++ project files and added missing files to
3292 Makefiles under win32/.
3294 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Do not add TCP_NODELAY flag if the operating system
3297 does not have it defined. Affected files are
3298 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3300 * Fixed buffer overflow from Irssi SILC Client. Affected
3301 file irssi/src/fe-common/core/themes.c.
3303 * Fixed double free in client library in the file
3304 lib/silcclient/client.c when disconnecting from server.
3306 * Applied double free patch from cras to Irssi SILC client.
3307 Affected files irssi/src/core/[modules/expandos].c
3309 * Fixed the disconnection handling to Irssi SILC Client.
3310 The application must call silc_client_close_connection
3311 in ops->connect client operation in case of failure of
3312 the connection. Affected file is
3313 irssi/src/silc/core/client_ops.c.
3315 * Do not set sock->protocol to NULL in the function
3316 silc_client_close_connection after executing the protocol's
3317 final callback since the sock might not be valid anymore.
3318 Affected file lib/silcclient/client.c.
3320 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Do not enable SILC_THREADS if the linking with libpthread
3323 did not happen. Affected file configure.in.pre.
3325 * Added notion to protocol specification that server must
3326 verify the sent authentication payload with CMODE when
3327 setting the channel founder key. Implemented it to the
3328 server. Affected file silcd/command.c.
3330 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3332 * Added _EXTRA_DIST SILC distribution variable to the
3333 distributions file. It is used to conditionally add extra
3334 files or directories to the specific distribution. Affected
3335 files ./prepare, Makefile.am.pre and distributions.
3337 Removed the `_' from the start of the distribution names.
3340 * Added README.WIN32 for instructions to compile the Toolkit
3343 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * Fixed a double free in disconnection in the server. Affected
3346 file is silcd/server.c.
3348 * Fixed the lib/silcske/groups.c to work now also with GMP
3349 MP library. The string conversion did not work when using
3350 specific base and the base is indicated in the string as well.
3352 * Created win32/ directory which now includes MSVC++ specific
3353 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3354 It will appear only in the toolkit distribution
3356 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3358 * Changed the key material distribution function in case when
3359 the hash output is too short. The data is now concatenated
3360 a bit differently than it used to. Made the change to the
3361 SKE protocol specification.
3363 * Added better GMP detection to configure.in.pre. A patch
3366 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Fixed a minor bug in SKE that might cause some problem on
3369 some platforms. Affected file lib/silcske/silcske.c.
3371 * Added the cookie checking for initiator in the SKE. It checks
3372 that the responder returns the sent cookie unmodified. The
3373 affected file is lib/silcske/silcske.c. Added new SKE
3374 error type INVALID_COOKIE that can be sent during the
3375 negotiation. Fixed some memory leaks as well.
3377 * Added the "invalid cookie" error message to Irssi SILC client's
3380 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Added `task_max' field to the SilcClientParams to indicate
3383 the maximum tasks the scheduler can handle. If set to zero,
3384 default values are used. Affected file lib/silcclient/silcapi.h.
3386 * Fixed memory leaks in silc_client_close_connection. Affected
3387 file lib/silcclient/client.c.
3389 * Added silc_client_del_client_entry to client library to free
3390 all memory of given client entry. Affected file is
3391 lib/silcclient/idlist.[ch].
3393 * Added new functions silc_client_del_channel and
3394 silc_client_del_server to delete channel and server entries.
3395 Affected file lib/silcclient/[silcapi.h/idlist.c].
3397 * Removed silc_client_del_client_by_id from silcapi.h.
3399 * Fixed the INFO command to return the server's own info
3400 correctly when querying by Server ID. Affected file is
3403 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3405 * Removed the non-blocking settings in WIN32 code in the
3406 silc_sock_[read/write] and added SleepEx instead. Affected
3407 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3408 of input data is now checked with FIONREAD and ioctlsocket.
3410 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * Call silc_schedule_task_del_by_context in the
3413 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3414 Affected file lib/silccore/silcprotocol.c.
3416 * Call silc_protocol_cancel for active protocols in the
3417 silc_server_close_connection if the funtion
3418 silc_server_free_sock_user_data has not been called.
3419 Affected file silcd/server.c.
3421 * Generic tasks cannot be deleted using the del_by_fd
3422 task deleting function since generic tasks does not match
3423 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3425 * Added a notion to SILCOPER help file that the SILCOPER works
3426 only on router server, not on normal server.
3428 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Added for WIN32 support for the new scheduler as well.
3431 Affected file lib/silcutil/win32/silcwin32schedule.c.
3433 * Fixed the SHA1 implementation to work on various platforms.
3435 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3438 API. It is part of the scheduler now. Everything else is
3439 as previously but some functions has changed their names.
3440 Checkout the lib/silcutil/silcschedule.h for the interface.
3441 Updated all applications to use the new interface. Affected
3442 files are lib/silcutil/silcschedule.[ch].
3444 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3446 * Found a bug in the SKE implementation. The HASH value,
3447 specified by the protocol, was not computed correctly. The
3448 public key of the responder was not added to the computation
3449 even though it is mandatory. Affected file lib/silcske/silcske.c.
3450 This unfortunately causes incompatibilities with older
3451 clients and servers.
3453 * Added WIN32 specific network init and uninit functions:
3454 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3455 the Winsock2. Affected file lib/silcutil/silcnet.h and
3456 lib/silcutil/win32/silcwin32net.c.
3458 * Set the socket always to nonblocking mode on WIN32 after
3459 reading data or writing data. Affected file is
3460 lib/silcutil/win32/silcwin32sockconn.c.
3462 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Fixed various compilation problems under WIN32. Affected
3465 files lib/silcutil/win32/silcwin32thread.c and
3466 lib/silcutil/win32/silcwin32schedule.c.
3468 * Removed all _internal.h #includes from public header
3469 files. Internal headers must never be included from
3472 Removed also the lib/silcske/payload_internal.h file.
3474 * All include files that may be needed (public and some others
3475 included by the public headers) by application developers are
3476 now copied to the ./includes directory. It does not copy any
3477 internal headers. Affected file Makefile.defines.pre and all
3478 Makefile.am's under lib/ and subdirs.
3480 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3482 * Do not change the ~/.silc directory's permissions automatically.
3483 Affected file irssi/src/silc/core/clientutil.c.
3485 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Do not cancel the protocol in silc_server_close_connection
3488 it might cause recursion. Now cancelled in the function
3489 silc_server_free_sock_user_data. Affected file silcd/server.c.
3491 * Fixed the silc_server_remove_clients_by_server to regenerate
3492 the channel keys correctly finally. Added also new function
3493 silc_server_remove_clients_channels to actually do it.
3494 Affected file silcd/server.c.
3496 * Fixed the silc_server_new_channel to not crash by giving
3497 wrong router to the new channel. Affected file is
3498 silcd/packet_receive.c.
3500 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3502 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3503 which is given as argument to the silc_client_alloc now.
3504 It can be used to configure the client and set various parameters
3505 that affect the function of the client.
3507 * The USERS command in server did not check whether the channel
3508 is private or secret. Affected file silcd/command.c.
3510 * Added new argument to the USERS command in protocol specification.
3511 The USERS command now can take the channel name as argument
3512 as well. Added support for this in client and server and
3513 updated the protocol specs.
3515 * Completed the GETKEY command in client. It can be now used
3516 to fetch also servers public key not only some clients.
3517 Affected files lib/silcclient/command[_reply].c.
3519 * Added silc_client_get_server to return server entry by the
3520 server name. Affected files lib/silcclient/silcapi.h and
3523 * Redefined the IDENTIFY command in protocol specification to be
3524 more generic. It now can be used to query information about
3525 any entity in the SILC Network, including clients, servers and
3526 channels. The query may be based either the entity's name
3527 or the ID. Added support for this in both client and server.
3529 Affected files silcd/command.c and lib/silcclient/command.c
3530 and command_reply.c.
3532 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3533 the _from_client and _from_server functions. Affected file
3536 * Added silc_client_get_channel_by_id_resolve to the file
3537 lib/silcclient/silcapi.h to resolve channel information by
3538 its ID. Added also silc_client_get_channel_by_id that
3539 does not resolve it from the server.
3541 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * Added SilcServerEntry context into the client library
3544 to represent one server. The INFO command now allocates
3545 these to save the resolved server info. For now on the
3546 client library will also keep information about servers,
3547 connected and resolved with INFO.
3549 The INFO command now allocates the SilcServerEntry context
3550 and saves the server info there. The COMMAND_REPLY in
3551 the INFO now returns the parameters to application in
3552 same order as defined in the protocol specification.
3554 The entries are cached in the client->server_cache.
3556 * The INFO command is now issued after received the Client ID
3557 from the server. Affected file lib/silcclient/client.c.
3559 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3560 to the application as the mode changer might be server.
3561 It is guaranteed that NULL is not returned anymore to the
3562 application. Affected file lib/silcclient/client_notify.c.
3564 The ID Type is now also passed to the application so that
3565 it can check whether the returned entry is SilcClientEntry
3568 Added new function silc_client_get_server_by_id to return
3569 the server entry by ID. Affected files are the
3570 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3572 * Do not create the channel in the Irssi SILC Client when issuing
3573 the JOIN command but when received the sucessful JOIN command
3574 reply. Otherwise the channel might get created even though we
3575 could not join it. The Affected file is
3576 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3578 * Fixed a channel joining bug in router. The router must also
3579 check the channel modes, invite and ban lists etc. when serving
3580 the JOIN command sent by normal server. Affected file is
3581 silcd/command.c. The router now resolves the client's
3582 information from the server who sent the JOIN command if it
3583 does not know it, and processes the JOIN command only after
3586 * Changed the SilcCommandCb to take new argument; void *context2.
3587 Affected file lib/silccore/silccommand.h
3589 The second argument in the command callbacks in the server now
3590 includes the SilcServerCommandReplyContext if the command was
3591 called as pending command callback from the command reply.
3592 Otherwise it is NULL. When called as pending the status of the
3593 command reply will be checked and if it was erronous the
3594 error will be sent to the original sender of the command.
3595 This way the client always receives the error messages even
3596 though the server was actually the one who received the error
3597 when it resent the command to router, for example. Affected
3598 files silcd/command[_reply].[ch].
3600 * Fixed sending WHOWAS command's error message to client if
3601 the requested client could not be found. It was missing.
3604 * Changed the CMODE and CUMODE commands reply arguments in the
3605 protocol specification. The Channel ID is now sent in both
3606 of the commands to identify the channel. Implemented this
3607 new feature to the client and server. Affected files
3608 lib/silcclient/command_reply.c and silcd/command.c.
3610 * Made better checks for invite and ban lists in the JOIN
3611 command in server. Affected file silcd/command.c.
3613 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * The server now performs the incoming host IP/DNS lookup
3616 using the silc_socket_host_lookup and thus does not block
3617 the server anymore. Affected file silcd/server.c.
3619 * Completed the multi-thread support for SILC Scheduler in
3620 the lib/silcutil/silcschedule.c.
3622 * Fixed the configure.in.pre to detect the pthread correctly
3625 * Fixed a deadlock in silc_task_queue_wakeup in the file
3626 lib/silcutil/silctask.c.
3628 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * Added new function silc_schedule_wakeup that is used in
3631 multi-threaded environment to wakeup the main thread's
3632 schduler. It needs to be used when a thread adds a new task
3633 or removes a task from task queues. After waking up, the
3634 scheduler will detect the task queue changes. If threads
3635 support is not compiled in this function has no effect.
3636 Implemented the wakeup mechanism to both Unix and WIN32
3637 systems. Affected files are lib/silcutil/silcschedule.[ch],
3638 lib/silcutil/unix/silcunixschedule.c and the
3639 lib/silcutil/win32/silcwin32schedule.c.
3641 * Added new function silc_task_queue_wakeup to wakeup the
3642 scheduler by the specified task queue. Affected file
3643 lib/silcutil/silctask.[ch].
3645 * The silc_socket_host_lookup_start now wakes up the scheduler
3646 after adding the timeout task. Affected file is
3647 lib/silcutil/silcsockconn.c.
3649 * The silc_socket_host_lookup is synchronous now if the threads
3650 support is not compiled in. However, the callback is still
3651 called asyncronously through the scheduler, anyway. Affected
3652 file lib/silcutil/silcsockconn.c.
3654 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3656 * Added new function silc_socket_host_lookup to perform
3657 asynchronous IP and FQDN lookups for the socket connection.
3658 Affected files lib/silcutil/silcsockconn.[ch].
3660 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3663 that may or may not compile the mutex support in.
3665 Changed the silc_mutex_alloc interface. It allocates the
3666 mutex now to the sent pointer and returns TRUE or FALSE.
3668 Affected file lib/silcutil/silcmutex.h.
3670 * Wrote the SILC Task Queue interface to support multi-threads.
3671 Affected file lib/silcutil/silctask.[ch].
3673 * Wrote the SILC Scheduler to support multi-threads. Affected
3674 file lib/silcutil/silcschedule.c.
3676 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3679 in lib/silcutil/win32/.
3681 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Defined SILC Mutex API and SILC Thread API and implemented
3684 them for Unix. Affected files are
3685 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3686 lib/silcutil/unix/silcunixmutex.c and
3687 lib/silcutil/unix/silcunixthread.c.
3689 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Fixed the silc_server_remove_clients_by_server's channel
3692 key re-generation. The hash table handling was incorrect
3693 and would not work with many channels. Affected file is
3696 * Fixed some memory leaks around the server code.
3698 * Rewrote the silc_server_get_users_on_channel to support IPv6
3699 based Client ID's. Affected file silcd/server.c.
3701 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3702 specification. However, a separate document must be written
3703 to define the detailed signing procedure and the payload
3704 associated with the flag. Defined the flag to the
3705 lib/silccore/silcchannel.h as well.
3707 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3709 * Changed the dynamic tables to static size tables in the
3710 lib/silccrypt/silchmac.c.
3712 * Removed GCC dependencies from the code. A patch by cras.
3714 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3716 * Do not show the error "Error receiving packet bla bla"
3717 in server if it really was not an error (-2 means that reading
3718 is pending). Affected file silcd/server.c.
3720 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * Fixed a possible crash in silc_server_remove_clients_by_server
3723 in silcd/server.c. Fixed there also some memory leaks.
3725 * Fixed the silc_idlist_replace_client_id. It could replace
3726 wrong key in the hash table. Affected file silcd/idlist.c.
3728 * Do not check whether there are global users on the channel
3729 if the channel->global_users is FALSE. Affected functions
3730 silc_server_remove_from_one_channel and
3731 silc_server_remove_from_channels in silcd/server.c. Also,
3732 do not check if the removed client is local as we can be
3733 sure that global client was not removed from the channel
3734 and checking for global users is not needed.
3736 * The silc_server_remove_clients_by_server now re-generates
3737 the channel keys correctly for those channels that had
3738 clients removed from them. Affected file silcd/server.c.
3740 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3742 * Found the reason of random crashes in the server. We weren't
3743 ignoring the SIGPIPE signal (which can be sent in write())
3744 and it crashed the server. Affected file silcd/silcd.c.
3746 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3748 * Assure that sock->user_data is not NULL in the function
3749 silc_server_packet_send in silcd/packet_send.c.
3751 * Disconnect the remote connection if it could not be added
3752 to any ID lists in the server. The affected file is
3755 * Check in silc_server_packet_send[_real/dest] that the
3756 socket is not disconnecting and ignore the data if it is.
3757 Affected file silcd/packet_send.c.
3759 * Define inline to __inline on native WIN32 compilation.
3760 Affected file includes/silcwin32.h.
3762 * Added some explicit type casts for inline code since MSVC
3763 require them. Affected files lib/silcutil/silcbuffer.h,
3764 lib/trq/silcdlist.h and lib/trq/silclist.h.
3766 * Print warning in log files from now on if the packet
3767 decryption fails. Affected file silcd/server.c.
3769 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Changed the `say' client operation's interface to accept
3772 new `type' argument to indicate the type of the message sent
3773 by the library. The application may filter the library's
3774 messages according the type. The affected file is the
3775 lib/silcclient/silcapi.h.
3777 * Added two new functions to lib/silcclient/silcapi.h:
3778 silc_client_del_client and silc_client_del_client_by_id.
3779 Affected file lib/silcclient/idlist.c.
3781 * Moved the clientincludes.h from includes/ to silc/ and
3782 serverincludes.h from includes/ to silcd/.
3784 * The modes for the CMODE and CUMODE are now passed as
3785 uint32 for application with COMMAND_REPLY. The affected
3786 file is lib/silcclient/command_reply.c.
3788 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3790 * /WHOIS without arguments shows client's own information.
3791 Affected file lib/silcclient/command.c.
3793 * Changed PING to not accept any arguments. The specs
3794 says that client can ping only the connected server so
3795 requiring an argument is not needed. Affected file is
3796 lib/silcclient/command.c.
3798 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * Fixed a fatal bug in private message sending and reception
3801 encryption and decryption when using private message keys.
3802 The implementation was incorrect and did not follow the
3803 specification. It causd that some of the message were
3804 lost since it did not use the sending and receiving keys
3805 as the protocol suggests. This has been fixed and will cause
3806 incompatibilities with older clients when sending private
3807 message encrypted with private message keys. Affected files
3808 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3809 and various other in Irssi SILC Client.
3811 Added `responder' boolean argument to the functions
3812 silc_client_add_private_message_key[_ske] to indicate when
3813 the key is added as responder or initiator of the key
3816 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Removed the silc_ske_check_version function and created
3819 a SilcSKECheckVersion callback. Added also a function
3820 silc_ske_set_callbacks that is now used to set all SKE
3821 callbacks. The callback functions are not given to
3822 the SKE functions anymore, but this function is used to
3825 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3827 * Added `silc_version' argument to the silc_client_alloc
3828 to define the version of the application for the library.
3829 The library will use the version string to compare it
3830 against the remote host's (usually a server) version
3831 string. Affected file lib/silcclient/silcapi.h
3833 * Added the KE protocol context to Key Agreement context
3834 in client library so that we can abort the SKE if it
3835 is in process when we get timeout. Affected file is
3836 lib/silcclient/client_keyagr.c.
3838 * Do not resolve the client ID forever if it returns in the
3839 first time that such client does not exist. This was done
3840 for example with private message. Affected file is
3841 lib/silcclient/client_prvmsg.c.
3843 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3845 * Do not add regex.h for WIN32. The affected file
3846 includes/silcincludes.h.
3848 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3849 not work yet 100%. It generates the DLL's automatically
3850 when compiling with --with-win32 under cygwin.
3852 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3854 * lib/contrib/regex.c is not compiled on WIN32.
3856 * Added silc_net_get_socket_opt function to the
3857 lib/silcutil/silcnet.h.
3859 * Added includes/silcwin32.h for WIN32 specific includes
3862 * Do not use ptime structure or any of the posix process
3863 functions on WIN32 in lib/silccrypt/silrng.c.
3865 * Added silc_gettimeofday to provide generic function
3866 for struct timeval on all platforms. Added the function
3867 to lib/silcutil/silcutil.h.
3869 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3872 library as they clearly belong there. As a plus side we
3873 can make the actual socket connection routines platform
3876 Added also new generic function silc_socket_read and
3877 silc_socket_write (that used to be silc_packet_[read/write].
3878 The implementation of these are platform specific.
3880 * Added WIN32 specific routines of silc_socket_[read/write]
3881 to lib/silcutil/win32/silcwin32sockconn.c.
3883 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3885 * Added preliminary support for native WIN32 compilation under
3886 cygwin (using the -mno-cygwin option for GCC) to the
3887 ./configure.in.pre. The --with-win32 now prepares the
3888 compilation for native WIN32.
3890 * Rewrote the SILC Scheduler interface in the file
3891 lib/silcutil/silcschedule.h. The scheduler is now context
3892 based and does not have anymore any global static scheduler.
3893 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3894 and created lib/silcutil/win32 directory for WIN32 based
3897 * Added Unix specific network routines to the
3898 lib/silcutil/unix/silcunixnet.c and the old
3899 lib/silcutil/silcnet.c includes now only generic routines.
3901 Added WIN32 specific network routines to the
3902 lib/silcutil/win32/silcwin32net.c.
3904 * Added Unix specific utility functions from the
3905 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3907 * Added WIN32 SILC Scheduler to the file
3908 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3911 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Do not handle JOIN notify in the server if the target client
3914 is not registered (idata->registered == FALSE). The affected
3915 file is silcd/packet_receive.c.
3917 * Update the nickrec->founder in event_cumode in the Irssi SILC
3918 client. Affected file irssi/src/silc/core/silc-channels.c.
3920 * Fixed the CUMODE_CHANGE notify handling in the server when
3921 server and router are announcing their clients on channels.
3922 Now the mode changes are saved and notified correctly. The
3923 affected file is /silcd/packet_receive.c.
3925 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3926 They really did not replace the cache entry in the ID Cache.
3927 Now they do that. Affected file silcd/idlist.c.
3929 * Fixed the KICK notify handling in the Irssi SILC client to
3930 update the channel records so that the kicked client does not
3931 appear to be on the channel. The affected file is
3932 irssi/src/silc/core/silc-channels.c.
3934 * Always update the conn->current_channel when executing command
3935 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3937 * Fixed the KILL notify handling in Irssi SILC client to remove
3938 the killed client on all channels.
3940 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Fixed the silc_parse_command_line to remove extra spaces
3943 from the start and end of the arguments. Affected file is
3944 lib/silcutil/silcutil.c.
3946 * Cancel and free any active protocol in the function
3947 silc_server_close_connection. Affected file silcd/server.c.
3949 * Cancel and free any active protocol in the function
3950 silc_client_close_connction. Affected file is
3951 lib/silcclient/client.c.
3953 * Do not execute the KILL command for clients that are in
3954 history (ie. they are not in the network). Affected file is
3957 * Fixed KILL notify handling, client does not crash anymore.
3958 Affected file irssi/src/silc/core/silc-channels.c.
3960 * Reduced the default packet buffer size from 2048 to 1024 in
3961 lib/silccore/silcpacket.c.
3963 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3964 counter to the SKE context that is incresed when the SKE library
3965 performs async operation outside the library. If the outside
3966 process frees the SKE context and FREED status will be set
3967 and the library will detect after the sync operation that the
3968 libary is freed. The affected files are
3969 lib/silcske/silcske[_status].[ch].
3971 * Resolve the client entry information in the function
3972 silc_client_channel_message to assure that NULL pointer is not
3973 passed as client entry to the application. */
3975 * Fixed the task timeout calculation to assure that there is
3976 never negative timeouts. The affected file is
3977 lib/silcutil/silcschedule.c.
3979 * Fixed the channel user mode notification sending in server.
3980 It was sent point-to-point to the router (or to server by router)
3981 but it needs to be destined to a channel. The routines now
3982 supports sending the channel user mode notifys to the channels
3983 when announcing clients and channels. Affected files are
3984 silcd/server.c and silcd/packet_receive.c.
3986 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3987 It did not actually replace the old channel entry in the cache.
3988 Affected file lib/silcclient/client_notify.c.
3990 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Fixed a possible crash in silc_packet_send_prepare. It now
3993 assures always that there is enough space in the buffer and
3994 at the tail area of the buffer (for MAC).
3996 Fixed the inbound buffer reallocation in silc_packet_read.
3997 It was old code and did not handle the reallocation correctly.
4000 The affected file is lib/silccore/silcpacket.c.
4002 * Fixed buffer overflow in silc_parse_nickname in the file
4003 lib/silcutil/silcutil.c.
4005 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * make install generates new server keys only if there is not
4010 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4013 Added check that if the NOREPLY is set then we will not send
4014 the away message. This avoids infinite loop of away messages
4015 if both clients are away. The affected file is
4016 lib/silcclient/client_prvmsg.c.
4018 * Fixed client crash if /NICK was given without arguments.
4019 Affected file lib/silcclient/command.c.
4021 * Server does not send the invite list in INVITE command back
4022 to the client if the list was not altered. Added this notion
4023 to the protocol spec as well. Affected file silcd/command.c.
4025 Fixed possible crash in INVITE command by checking the
4026 value of silc_server_get_client_route command.
4028 * Fixed the INVITE notify type handling. The arguments are now
4029 taken in correct order and client does not crash. The affected
4030 file is irssi/src/silc/core/silc-channels.c.
4032 Removed the "Inviting xxx to channel" message from the
4033 client library away and let the application handle it.
4034 Affected file lib/silcclient/command.c. Added that message
4035 to Irssi SILC client's message formats.
4037 * Fixed CMODE command crash in client. It now checks the
4038 amount of arguments correctly and does not crash. The affected
4039 file is lib/silcclient/command.c.
4041 * Do not create new channel automatically in silc_channels_join
4042 but check whether the channel by that name already exists.
4043 Affected file irssi/silc/core/silc-channels.c.
4045 * Do not send the SERVER_SIGNOFF to router if the disconnected
4046 entity was the router. Affected file silcd/server.c.
4048 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4049 SILC client as it was missing from there.
4051 Added the handling of the KICK notify to the Irssi SILC client
4052 as it was missing. Added "you have been kicked" message to
4053 Irssi SILC client's message modules formats.
4055 Added the handing of the KILL notify to the Irssi SILC client
4056 as it was missing. Added the kill message module formats
4059 The affected file is irssi/src/silc/core/silc-channels.c.
4061 * The router did not save the channel mode the server announced.
4062 Affected file silcd/packet_receive.c.
4064 * Fixed a possible crash in INFO command in server. If the
4065 server did not provide the server info it crashed. Affected
4066 file silcd/command.c.
4068 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Fixed the GETKEY command in the server to check also the
4071 global list. Otherwise the GETKEY would not work correctly
4072 in normal SILC server. Affected file silcd/command.c.
4074 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Fixed GETKEY crash, it crashed if the command did not succseed.
4078 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4081 is now real and not just an macro interface to GMP.
4083 Removed the entire GMP from the source tree and imported new
4084 NSS MPI library instead. Reason for removing GMP is that it is
4085 extremely large and compiles extremely slow. The NSS MPI
4086 is only a few files and compiles in less than 10 seconds.
4087 The speed is also about the same as GMP. The MPI is imported
4088 to lib/silcmath/mpi.
4090 If the system has GMP installed we will still use the GMP.
4091 If it is not then the NSS MPI will be compiled.
4093 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * Merged a long nickname (127 characters long) crash bugfix from
4096 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4098 * Merged a freed memory reference bugfix from Irssi CVS tree.
4099 Affected file irssi/src/core/commands.c.
4101 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Added the server's public key sving and verification to the
4104 server when performing the SKE. This was missing and the
4105 remote server's (or router's) public key was accepted without
4106 checking whether we have it previously or trust it at all.
4107 Affected file silcd/protocol.c.
4109 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Check in the silc_server_timeout_remote if protocol is active
4112 and make sure that the protocol's final callback is called so
4113 that all memory if freed. Affected file silcd/server.c.
4115 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * silc_server_whois_send_reply crashed the server if the nickname
4118 was 127 characters long. Affected file silcd/command.c.
4120 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Added sanity check to the silc_server_new_client. If the hostname
4123 is provided inside username then check that the provided hostname
4124 really is the same as the resolved one. If the hostname was not
4125 resolved then check it from the public key. Affected file is
4126 silcd/packet_receive.c.
4128 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4129 if the server disconnected us and the connection is not valid
4130 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4132 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4133 the library to the lib/silcutil/silcutil.[ch].
4135 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Close log file after open. Affected file
4138 lib/silcutil/silclog.c.
4140 * Check whether sock == NULL in silc_client_send_packet and return
4141 if it is. Affected file lib/silcclient/silcclient.c.
4143 * Check rec->entry == NULL in the Irssi SILC Client before
4144 sending the channel message. Affecte file is
4145 irssi/src/silc/core/silc-servers.c.
4147 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Merged a splitted window bugfix from Irssi CVS tree. The
4150 affected file is irssi/src/fe-text/textbuffer-view.c.
4152 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4153 It did not print nickname.
4155 * Improved the distributions system a bit.
4157 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4160 irssi/src/fe-text/gui-window.c.
4162 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4163 to in-active server. The affected file is
4164 irssi/src/silc/core/client_ops.c.
4166 * Resolve the client in USERS command reply if the entry does
4167 not have username resolved. The affected file is
4168 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4169 command to WHOIS command to really resolve stuff. The USERS
4170 is not used any more in any critical section so WHOIS can
4171 be used even though it might be slower than IDENTIFY.
4173 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4176 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Changed the protocol API a bit more consistent in the
4179 lib/silccore/silcprotocol.[ch].
4181 * Changed the following headers to ROBODoc format:
4183 lib/silccore/silcpayload.h
4184 lib/silccore/silcprotocol.h
4185 lib/silccore/silcsockconn.h
4187 All core library headers are now formatted.
4189 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Fixed a bug in Irssi SILC client; do not show that you are
4192 server/router operator if you really are not. Affected file is
4193 irssi/src/silc/core/client_ops.c.
4195 * Renamed silc_command_free_payload to silc_command_payload_free.
4196 Affected file lib/silccore/silccommand.h
4198 * Added silcmath.h to include the prototoypes of various routines
4199 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4202 * Changed the following headers to ROBODoc format:
4204 lib/silccore/silcchannel.h
4205 lib/silccore/silccommand.h
4206 lib/silccore/silcid.h
4207 lib/silccore/silcidcache.h
4208 lib/silccore/silcmode.h
4209 lib/silccore/silcnotify.h
4210 lib/silccore/silcpacket.h
4211 lib/silcmath/silcmath.h
4213 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Added checking to the server code not to start the server if
4216 ciphers and stuff are not configured properly. Affected files
4217 silcd/serverconfig.[h] and silcd/server.c.
4219 * Changed the layout of the header files of the public interfaces
4220 in the SILC libraries. The new layout supports ROBODoc
4221 documentation tool (and some others) so that it is easy to create
4222 a library reference manual. All the other headers and source
4223 code must still follow the CodingStyle document. Also source
4224 code must not include these ROBODoc stuffs, only the headers.
4225 Furthermore, all public interface headers must now be named
4226 by using `silc' prefix, example: silcapi.h, silccipher.h.
4227 Some files were renamed due to this. All the other headers
4228 must not be used as public interfaces. I will update the
4229 CodingStyle document later. Changed following headers, so far:
4231 lib/silcclient/silcapi.h
4232 lib/silccore/silcauth.h
4233 lib/silccore/silcprivate.h
4234 lib/silccrypt/silcdh.h
4236 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Removed silc_client_packet_send_flush from the client library
4241 as it is not needed. Affected file lib/silcclient/client.[ch].
4243 * Added printing of message of unresolved authentication method
4244 to the Irssi SILC client. Added it to the module formats.
4245 Removed the same message from the client library.
4247 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Added new distribution feature, DISTLABEL. Every distribution
4250 can define own preprocessor label that can be used in the
4251 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4252 file distributions, acconfig.h.pre and prepare.
4254 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added Makefile.defines_int to include the actual definitions
4257 for Makefile.defines.in. Tested the new distribution system,
4258 created distributions and tested installation.
4260 * Added AWAY message printing to the Irssi SILC client. Added
4261 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4263 * Added SCONNECT command to call the SILC's CONNECT command.
4264 Cannot use CONNECT directly since Irssi uses that internally.
4265 Affected file irssi/src/silc/core/silc-servers.c.
4267 Added ACTION local command. It is same as ME command but takes
4268 the channel as mandatory argument.
4270 Rewrote some of the Irssi's help files to suite for SILC
4273 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Added Makefile.defines[.in] that should for now on be included
4276 in all Makefile.am file in the source tree. That file includes
4277 all common compilation definitions for SILC source tree.
4279 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4281 * Minor changes to the ./prepare script to change the package
4282 name according the distribution name to the configure.in.
4284 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Created new distribution system. Added file `distributions'
4287 that defines all the distributions that can be created out of
4288 the SILC source tree. The ./prepare script now reads that
4289 file to determine how to prepare the distributions. The
4290 first argument to the ./prepare is the name of the distribution
4291 and second is the version of the distribution. If given
4292 without arguments it creates the default (toolkit) distribution
4293 with the default version (defined in ./prepare).
4295 All Makefile.am files that are subject to the distributions
4296 are now named as Makefile.am.pre. These are ./Makefile.am
4297 and lib/Makefile.am. Others may be changed later.
4299 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Added invite list, ban list, some key management and connection
4302 error message printing to module formats in the Irssi SILC client.
4304 * Added new silc_client_set_away_message to set the away message
4305 that is back to the person who sent private message. The
4306 affected file lib/silcclient/silcapi.h and the
4307 lib/silcclient/client_prvmsg.c.
4309 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Fixed the private message sending in the Irssi SILC client,
4312 added local command KEY to the Irssi SILC client.
4314 Added key management and key agreement message formats to the
4315 irssi/src/fe-common/silc/module-formats.[ch].
4317 Added USERS (alias WHO) printing, server/router operator
4318 indication and LIST command printing to the module formats.
4320 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Fixed channel joining notify handling, cumode notify handling
4323 from Irssi SILC client.
4325 * Added SILC specific module-formats to the Irssi SILC client so
4326 that SILC specific message hilighting, colors etc is possible.
4327 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4329 Added channel mode, channel user mode, actions, notices,
4330 whois and whowas printing to the the module-formats.c.
4332 * Fixed a bug in channel deletion in the server. The channel
4333 is not left to the cache even if the channel founder auth mode
4334 is set when there are no users anymore on the channel. Affected
4335 file silcd/server.c.
4337 * The silc_net_localhost now resolves the entire hostname including
4338 the domain name. Affected file lib/silcutil/silcnet.c.
4340 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Changed the ask_passphrase client operation to be ascynchronous.
4343 It has now a completion callback and a context that the
4344 application must call after it has got the passphrase from
4345 the user. Affected files lib/silcclient/silcapi.h,
4346 lib/silcclient/protocol.c, lib/silcclient/command.c and
4349 Added SilcAskPassphrase callback that the application calls
4350 to deliver the passphrase to the library.
4352 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4353 The public key verification and especially a certificate
4354 verification is asynchronous procedure.
4356 Added new SILC_SKE_STATUS_PENDING status to indicate the
4357 request is pending and a callback will be called to finalize
4360 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4361 indicate that remote end did not send its public key (or
4362 certificate), even though we require it. Added check for this
4363 condition in the SKE. This was a security bug, now fixed.
4365 Defined new SilcSKEVerifyCbCompletion callback that is called
4366 when the verification process is completed.
4368 The affected files lib/silcske/silcske_status.h and
4369 lib/silcske/silcske.[ch].
4371 * Changed the verify_public_key client operation to be async
4372 as well. Defined SilcVerifyPublicKey callback that is used to
4373 indicate the success of the public key verification process.
4375 Changed the server and client to use the new async client
4378 * Changed the Irssi SILC client's internal scheduler to be called
4379 twice as many times as it used to be. As a result the client
4380 should be a bit faster now. Affected file is
4381 irssi/src/silc/core/silc-core.c.
4383 * Added support to Irssi SILC client of asynchronous public key
4384 verification and passphrase inquiry. Affected file is
4385 irssi/src/silc/core/silc-core.c.
4387 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Do not say "You have left channel %s" in client library.
4390 Moved it to the application. Affected files are
4391 lib/silcclient/command.c and silc/client_ops.c.
4393 * Fixed silc_client_get_clients. Command context was not
4394 duplicated and was freed memory in the callback. Affected
4395 file lib/silcclient/idlist.c.
4397 * Do not say "you are now talking..." on JOIN command in the
4398 client library. The appliation must handle it.
4400 * Do not say ".. changed topic to" in command reply in the
4401 client libary. The application must handle it.
4403 * Fixed TOPIC command sending in the client library.
4405 * Fixed a memory leak in silc_client_command_free in the file
4406 lib/silcclient/command.c.
4408 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Imported a modified version of Irssi client to the source tree.
4411 The Irssi will be used to create a new client called
4412 Irssi SILC. Imported to irssi/.
4414 Added silc_core_init_finish function to the Irssi. Affected
4415 file irssi/configure.in.
4417 A lot changes in the Makefile.ams around the irssi tree.
4419 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Do not rehash if the new size is same as the old size of the
4422 hash table, in the silc_hash_table_rehash*. The affected file
4423 lib/silcutil/silchashtable.c.
4425 * Replaced hash_table_del_by_context calls from the server
4426 (when channel->user_list and client->channels) to the
4427 hash_table_del as it is sufficient and faster.
4429 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Added silc_hash_table_list, silc_hash_table_get and the
4432 SilcHashTableList structure to provide an alternative way to
4433 traverse the hash table. The affected files are
4434 lib/silcutil/silchashtable.[ch].
4436 * Changed the server's idlist routines to use the hash table
4437 routines to optimize the code.
4439 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Replaced the client entry's `channel' list and channel entry's
4442 `user_list' list to hash tables for optimized lookup. Changed
4443 the code to use the hash table interface around the code.
4444 Affected file lib/silcd/idlist.[ch].
4446 * Added `auto_rehash' boolean argument to the function
4447 silc_hash_table_alloc to indicate whether the hash table should
4448 auto-rehash when it thinks is appropriate time. It will
4449 increase the hash table size if the there is twice as much
4450 entries in the table than the size of the table, and will
4451 decrease the size if there are twice as less entries than
4452 the size of the table.
4454 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4458 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * silc_idcache_purge_by_context deletes the entry now by context
4461 as it is supposed to do. Affected file lib/silccore/idcache.c.
4463 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4464 client is not anymore valid (WHOWAS givens the info) and not
4465 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4467 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Removed the `data' and `data_len' arguments from the ID Cache
4470 interfaces and added `name' argument. ID Cache does not handle
4471 anymore the binary data only a names associated with given ID.
4473 * When hashing a Client ID with silc_hash_id the entire ID is
4474 not hashed anymore, instead only the hash of the Client ID is
4475 hashed. This way we can access the Client ID from the cache
4476 with Client ID but with the hash of the ID (which is a hash of
4477 the nickname) as well without any difference in performance.
4479 Added also silc_idcache_find_by_id_one_ext to do one on one
4480 searching when we have the actual ID. Added also function
4481 silc_hash_client_id_compare. The affected files are
4482 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4484 * When hashing the name associated with a ID it is always done
4485 in lowercase. This way we can access the cache without worrying
4486 about case-sensitivity, even though, for example nicknames are
4489 * Fixed a bug in server with channel message sending. It put
4490 wrong ID type as destination ID. The affected file
4491 silcd/packet_send.c.
4493 * silc_idcache_del_by_context now deletes from all hash tables
4494 by context. Affected file lib/silccore/idcache.c.
4496 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Changed the client library to use the new ID Cache interface.
4499 Changes around the source tree.
4501 * Added silc_hash_table_rehash_ext to rehash with specific
4502 hash function. Affected file lib/silcutil/silchashtable.[ch].
4504 * Added silc_hash_string_compare to compare two strings in the
4505 hash table. Affected file lib/silcutil/silcutil.[ch].
4507 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Added new function silc_idcache_del_by_context into the
4510 lib/silccore/idcache.[ch].
4512 * Changed the server's ID list routines to use the new ID Cache
4513 interface. Changes around the source tree.
4515 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Added silc_hash_table_del[_by_context]_ext functions in to the
4518 lib/silcutil/silchashtable.[ch].
4520 Removed silc_hash_table_find_all* routines and added new
4521 silc_hash_table_find_foreach to replace them.
4523 Added silc_hash_table_replace_ext function as extended
4524 replacing function. Separated the simple hash table interface
4525 from the extended hash table interface in the file
4526 lib/silcutil/silchashtable.h.
4528 * Fixed minor bugs and changed it to use some of the new
4529 hash table functions in lib/silccore/idcache.c
4531 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Added new function silc_hash_table_find_all to return all keys
4534 in the hash table by the specified key. As the hash table is
4535 collision resistant it also makes it possible to have several
4536 duplicate keys in the hash table. This function may be used to
4537 find all of the keys from the hash.
4539 Added user_context arguments to the SilcHashFunction,
4540 SilcHashCompare and SilcHashDestructor to deliver user specified
4543 Added new fuctions silc_hash_table_find[_all]_ext to do
4544 extended lookup with specified hash and compare functions and
4545 specified user contexts.
4547 Added new function silc_hash_table_add_ext to add the key
4548 with specified hash function and user context.
4550 Added new function silc_hash_table_foreach to traverse all
4551 entrys in the hash table. Added SilcHashForeach callback
4554 Added new function silc_hash_table_del_by_context to delete
4555 the entry only if the context associated with the key matches.
4557 Affected files are lib/silcutil/silchashtable.[ch].
4559 * Removed silc_hash_[server/client/channel]_id and added just
4560 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4561 silc_hash_id_compare to compare two ID's using as the hash table
4562 comparison function. Added also silc_hash_data to hash
4563 binary data and silc_hash_data_compare to compare it.
4565 * Removed silc_idlist_find_client_by_hash as it is not needed
4566 anymore. Affected file silcd/idlist.[ch].
4568 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4569 to use internally the SilcHashTable. The new ID Cache is a lot
4570 faster than the old one. Some of the ID Cache interface was also
4571 rewritten and obsolete and stupid functions were removed.
4573 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added entry_count field to the SilcHashTable to keep the number
4576 of the entries in the table. Implemented the function
4577 silc_hash_table_rehash. Added new function
4578 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4580 Fixed a minor bug in silc_hash_table_free.
4582 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4583 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4584 into the lib/silcutil/silcutil.[ch].
4586 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Implemented a collision resistant hash table into the
4589 lib/silcutil/silchashtable[ch]. See the header and the source
4590 for the SilcHashTable API.
4592 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Merged dotconf version 1.0.2 into lib/dotconf.
4596 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Do not compile anything in lib/silcsim/* if the SIM support
4599 is not enabled. The tree should now compile without problems
4602 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Compiled the SILC under cygwin. Compiled and tested briefly
4605 without problems. More tests needed. The SIMs didn't compile
4608 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4610 * Fixed possible crash in silc_get_username in the
4611 lib/silcutil/silcutil.c.
4613 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Fixed a va_arg in silc/client_ops.c.
4617 * Oops, RC5 routines were named AES and caused some problems
4618 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4620 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added new SilcIDIP structure into the lib/silccore/id.h and
4623 replaced the old `ip' fields from all SILC ID's to that type.
4624 This is a step towards IPv6 support.
4626 The silc_id_get_len takes now the ID as an extra argument.
4627 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4628 both IPv4 and IPv6 based ID's.
4630 The affected files are lib/silccore/id.[ch] and other files
4631 around the tree using these routines.
4633 * Removed the ID length arguments in server from various
4634 silc_server_send_notify_* routines -> they are not needed
4637 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Fixed memory leak in silc_encode_pem_file in the file
4640 lib/silcutil/silcutil.c.
4642 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Check minor version as well in the SKE. Affected files are
4645 silcd/protocol.c and lib/silcclient/protocol.c.
4647 * Added --identifier option to the server so that an identifier
4648 can be when creating the public key for the server. Affected
4649 file is silcd/silcd.c.
4651 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4652 lib/silccrypt/silcpkcs.c.
4654 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Register default ciphers and stuff when using -C option with
4657 the server. Affected file sildc/silcd.c.
4659 * Put back the servers public key filename format, it is better
4660 than the new one. For now, the client keys are saved with the
4661 new filename format. The affected file silc/client_ops.c.
4663 * Implemented the Cipher API for the rest of the ciphers that
4664 did not implement it or implemented it the wrong way.
4666 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Register default ciphers and stuff when using the -S option
4669 in the client. Affected file silc/silc.c. Same also when
4670 creating new key pair with -C option.
4672 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Fixed the silc_verify_public_key client operation function to
4675 save the public keys differently. The fingerprint is now
4676 used as filename and not the hostname. This way also the
4677 client keys are saved uniquely and not with hostnames. The
4678 affected file is silc/client_ops.c.
4680 * Trimmed the silc_hash_fingerprint function to remove extra
4681 whitespaces from the end of the fingerprint. The affected
4682 file is lib/silccrypt/silchash.c.
4686 * Added silc_cipher_register_default function to register all
4687 default ciphers. It can be used when configuration files
4688 does not exist and the application does not want any specific
4689 ciphers in any specific order.
4691 The SilcDList is now used as silc_cipher_list dynamically
4692 allocated cipher list. Removed the static list all together
4693 and now all ciphers must be allocated to the dynamic list.
4694 The silc_cipher_alloc routine was changed to check only the
4697 All silc_cipher_* routines that used to return int returns
4700 The affected files lib/silccrypt/silccrypt.[ch].
4702 * The same thing was done to silc_hash_* as for silc_cipher_*
4703 routines. Affected files lib/silccrypt/silchash.[ch].
4705 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4706 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4707 Added also silc_pkcs_[un]register[_default] functions.
4708 Removed the data_context from the PKCS API.
4710 * Added silc_hmac_register_default function to register default
4711 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4712 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4713 to unregister all hmacs at once.
4715 * Register the default ciphers, hash functions, PKCSs and HMACs
4716 if client's configuration file does not exist. The affected
4719 * The client did not load the hash functions from the SIM
4720 modules at all. Added support for this. Affected file is
4721 silc/clientconfig.c.
4723 * When decoding public key with silc_pkcs_public_key_decode, check
4724 the supported algorithm only if PKCS are registered. Affected
4725 file lib/silccrypt/silcpkcs.c. The same was done with the
4726 silc_pkcs_private_key_decode.
4728 * Fixed the SILC List routines to keep the list always in order.
4729 It used to change the list's order when traversing the list but
4730 not it preserves the order. Affected file lib/trq/silclist.h.
4732 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Added the client library to use the SilcSocketConnection's
4735 reference counter (by silc_socket_dup) to prevent the bug that
4736 the socket object may be freed underneath async operation.
4738 * The name resolv library checking fixes in the configure.in.pre.
4741 * Created new version of the protocol drafts for future
4742 development. The -03 drafts are the ones that will be changed
4743 in the trunk now and the -02 will remain as they are.
4745 * Send list of CUMODE notifys to the router when announcing
4746 the channel users to the router. Affected file silcd/server.c.
4747 If the router receiving channel founder CUMODE for a channel
4748 that already has channel founder it will send CUMODE notify
4749 to the sender to remove the channel founder rights from the
4750 announced client. Affected file silcd/packet_receive.c.
4752 * The CUMODE notify may now use Server ID as well as the entity
4753 who changes the mode. Updated protocool specs.
4755 * Updated INSTALL and README files.
4757 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * New web pages in the http://silc.pspt.fi. The pages was
4764 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Implemented the [DenyConnectin] config section in the server.
4767 Added silc_server_config_denied_conn to check whether incoming
4768 connection is denied. Affected file silcd/serverconfig.[ch].
4770 * Do not check the ports when checking the incoming configuration
4771 data if the port is 0, meaning any. Affected file is
4772 silcd/serverconfig.c.
4774 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Fixed buffer overflow in silc_string_compare in the file
4777 lib/silcutil/silcutil.c.
4779 * Fixed double free in silc_server_command_leave in the file
4782 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Fixed the version checking in the server. Affected file is
4787 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Fixed the configuration data fetching when accepting new
4790 connections in the server. Affected file silcd/server.c.
4792 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Added `sender_entry' argument to the function
4795 silc_server_packet_relay_to_channel so that we can check
4796 whether some destination actually belongs to the same route
4797 the sender belongs (ie, we must not resend the packet to the
4798 sender). Affected file silcd/packet_send.[ch].
4800 * Added `servername' field to the SilcClientEntry in the server
4801 to hold the name of the server where client is from. Affected
4802 file is silcd/idlist.h.
4804 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Moved the channel message encrypting in the router betwen
4807 router connections from silc_server_channel_message to the
4808 silc_server_packet_relay_to_channel since we want to check
4809 whether we have anybody channel before encrypting anything.
4810 Affected files silcd/packet_[receive/send].c.
4812 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Fixed the [AdminConnection] server config section to support
4815 multiple entries. Affected file silcd/serverconfig.c.
4817 * Added support into the server to check the validity of the
4818 incoming connection before executing any KE or authentication
4821 * The connection configuration is now saved to the KE and
4822 connection auth protocol contexts and not fetched anymore in
4823 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4825 * The local hosts listenning address and port is also resolved
4826 now when starting the server. We want to have the socket object
4827 to include the real address and port for the listener. Added
4828 new function silc_net_check_local_by_sock into the files
4829 lib/silcutil/silcnet.[ch].
4831 * Fixed a broadcast bug in server -> do not broadcast if we
4834 * Fixed a routing bug. Do not route broadcast packets ever.
4835 Broadcast packets must be processed always and not routed since
4836 they may be destined to some other host than yourself and thus
4837 would get routed without no good reason. Affected file is
4840 * Added function silc_server_config_is_primary_route to check
4841 whether primary router connection has been configured (a router
4842 configuration that we are initiating). If there is not, we
4843 will assume that there is only two routers in the SILC network
4844 and we will use the incoming router connection as our primary
4845 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4847 * Changed the order of the broadcasting. Broadcast _after_ the
4848 packet has been processed not before. Affected file is
4851 * Fixed a [ClientConnection] parsing bug. The port was never
4852 parsed correctly thus resulting to port 0. Affected file
4853 silcd/serverconfig.c.
4855 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4856 argument and did not set the broadcast packet flag. Affected
4857 file silcd/packet_send.c. Fixed same bug in the function
4858 silc_server_send_notify as well.
4860 * If we receive NEW_ID packet for our own ID in the server, ignore
4863 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Removed the nickname from the Private Message Payload.
4868 Updated the code and the protocol specs.
4870 * Updated protocol specs for submitting to the IETF.
4872 * Tweaked the Random Number Generator a bit. Affected file
4873 lib/silccrypt/silcrng.c. Exported a new function
4874 silc_rng_[global]_add_noise which can be used to add more
4877 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Do not parse packets with different timeout when protocol
4880 is active -> may cause problem with rekey. Affected file
4883 * When server receives signoff notify it must not create
4884 new channel key if the client is on any channels since the
4885 sender of the signoff notify will create it.
4887 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added printing of error messages during SKE protocol from the
4890 failure packet sent by server during SKE. Affected file
4893 * Removed the client's failure_callback handling with timeout
4894 and handle it immediately when received.
4896 * The SKE library returned wrong type in SUCCESS and FAILURE
4897 packets. They must be 32 bit MSB not 16 bit MSB.
4899 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Ok, rewrote the logic of the re-key and now it seems to work.
4902 I tested it on high traffic with frequent re-keys without
4903 problems. Added hmac_receive (and renamed hmac to hmac_send)
4904 in SilcClientConnection in lib/silcclient/client.h and
4905 in SilcIDListData in silcd/idlist.h. Also, removed the
4906 SilcPacketParserContext's cipher and hmac fields as they are
4907 not needed anymore and actually caused some problems when
4908 the ciphers and hmac's changed underneath the packet parser.
4910 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * If re-key protocol is active then process the incoming packets
4913 synchronously since we must assure that icoming packets encrypted
4914 with the old key is processed before the new keys is set to
4915 use. This is true other packets than for REKEY packets.
4916 Affected file silcd/server.c. The same was done to client library
4917 as well, affected file lib/silcclient/client.c.
4919 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Fixed bug in client and server to accept the force send if
4922 the packet is send from silc_[server/client]_packet_process
4923 function. Otherwise the packets are never delivered, oops.
4925 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Disable force sending of packets when REKEY protocol is active.
4928 We must assure that no packet is sent directly when rekey is
4929 performed. All packets must be sent through packet queue.
4930 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4931 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4932 function is silc_[server/client]_packet_send_real to check
4935 * Replaced the SIM paths from example config files to
4936 /usr/local/modules. Also, make install creates now
4937 /usr/local/silc/logs directory to hold all the SILC server
4940 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Made the configure.in.pre work on Solaris. Patch by salo.
4944 * Made all ciphers compatible with non-x86 machines. Defined
4945 CBC mode macros into lib/silccrypt/ciphers_def.h.
4947 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed the make install.
4951 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * When MAC computation fails the silc_packet_decrypt returned 0
4954 even though it was supposed to return -1. Fixed this. The
4955 affected file is lib/silccore/silcpacket.c.
4957 * Do not replace the config files in /etc/silc (in make install)
4958 if they already exist. Affected file ./Makefile.am.
4960 * Do not send re-key packets immediately but through packet queue.
4961 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4963 * Changed silc_net_check_host_by_sock to return FALSE if the
4964 IP/DNS could not be resolved. Though, it returns the IP address
4965 now even if it could not resolve it (but returns also FALSE).
4966 Affected file lib/silcutil/silcnet.[ch].
4968 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Added silc_pkcs_decode_identifier to decode the public key's
4971 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4972 Added also silc_pkcs_free_identifier. Added also new context
4973 SilcPublicKeyIdentifier.
4975 * Added -S option to the silc client. It is used to dump the
4976 contents of the specified public key file.
4978 * Changed the PKCS api to return the public key length when
4979 setting the public key.
4981 * Fixed a fatal bug in the public and private key file loading.
4982 Affected file lib/silccrypt/silcpkcs.c.
4984 * Execute the packet parsing for client with zero (0) timeout
4985 if the protocol is active. Affected file silcd/server.c.
4987 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Made the key generation options to the silcd program. Added
4990 -C option, equivalent to client's option.
4992 * Added new [ServerKeys] config section to the server. It
4993 configures the server's public and private key.
4995 * Defined generic Public Key Payload into the protocol
4996 specification to send specific type of public keys and
4999 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5000 public key or certificate.
5002 * Implemented the GETKEY command to the server and to the
5003 client library and on user interface.
5005 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Made preliminary `make install' work.
5009 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added SilcServerRekey context into silcd/idlist.h.
5013 * Added the PFS support as defined in the specification to the
5014 SKE protocol. Affected files lib/silcske/*.c.
5016 * Added `ske_group' field to the SilcServerRekey context to hold
5017 the number of the SKE group that is used with PFS in re-key.
5018 Affected file silcd/idlist.h.
5020 * Added PFS re-key support to the server. Affected file is
5023 * Added silc_protocol_cancel to cancel execution of the next
5024 state of the protocol. Affected file is
5025 lib/silccore/silcprotocol.[ch].
5027 * Added the re-key support with and without PFS to the client
5028 library. Re-key is performed once in an hour, by default.
5030 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5031 Added silc_client_rekey_callback and silc_client_rekey_final.
5032 Affected files are lib/silcclient/protocol.[ch] and
5033 lib/silcclient/client.[ch].
5035 * Removed the `hmac_key' and `hmac_key_len' fields from the
5036 SilcClientConnection structure; not needed. Affected file is
5037 lib/silcclient/client.h.
5041 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Do not ask whether user wants to use the negotiated private key
5044 for private messages, just use it. Affected file is
5045 silc/local_command.c.
5047 * Added `send_enc_key' and `enc_key_len' fields to the
5048 SilcIDListData structure since they are needed in the re-key
5049 phase. Affected file is silcd/idlist.[ch].
5051 * Implemented the simple re-key protocol into the server.
5052 Affected files silcd/server.c and silcd/protocol.[ch]. The
5053 re-key will be performed once in an hour, by default.
5055 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5056 Added silc_server_rekey, silc_server_rekey_callback and
5057 silc_server_rekey_final.
5059 * Removed Tunneled flag from the protocol. Updated the code
5060 and the specifications.
5062 * Adde `pfs' field to the SilcIDListData to indicate whether
5063 the PFS is to be performed in the re-key. Affected file is
5066 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5069 int64 of at least the xintXX size. If void * is less that 4
5070 bytes uint32 * will be used. Defined bool as boolean.
5072 * Changed _ALL_ unsigned long and unsigned int to uint32,
5073 unsgined short to uint16 in the source tree.
5075 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5076 not handle clients that has entry->data.registered == FALSE.
5077 They are not in the network anymore. Affected file is
5080 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Implemented the sending of the SERVER_SIGNOFF notify in the
5083 server. Affected file is silcd/server.c.
5085 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5086 Added also silc_notify_payload_encode_args into the
5087 lib/silccore/silcnotify.[ch].
5089 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5090 Affected file silcd/packet_receive.c.
5092 * Implemented the SERVER_SIGNOFF notify handling in the client
5093 library. Affected file lib/silcclient/client_notify.c. Also,
5094 implemnted the printing of the SERVER_SIGNOFF info to the
5095 application. Affected file silc/client_ops.c.
5097 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5098 if the deleting was successful. Affected file silcd/idlist.[ch].
5100 * Added support for public key authentication in the connection
5101 authentication protocol in the client library. Affected file
5102 lib/silcclient/protocol.c.
5104 * Changed the server's silc_idlist_get_clients_by_* interface
5105 to support already allocated array so that new entries may be
5106 added to pre-allocated array. Affected file silcd/idlist.[ch].
5107 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5108 and command replies.
5110 * All command reply functions in the server now calls the
5111 pending command callback even if error occured. This way the
5112 error will be delivered to the client as well. Affected files
5113 silcd/command.c and silcd/command_reply.c.
5115 * Fixed INFO command to return local server's info if no server
5116 was provided. Affected file lib/silcclient/command.c.
5118 * Removed RESTART command for good. Updated the code and the
5121 * Rewrote parts of the task system. It is a bit simpler now.
5122 Removed unsued task priorities. The affected files are
5123 lib/silcutil/silctask.[ch].
5125 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Moved the USERS printing from the library to the application.
5128 Affected files lib/silcclient/command.c and silc/client_ops.c.
5130 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * Added channel key re-key support. The re-key is perfomed
5135 only by the router and is done once in an hour. Added `rekey'
5136 field to the SilcChannelEntry in the server. Affected files
5137 silcd/server.c and silcd/idlist.h.
5139 * Added silc_task_unregister_by_context into the file
5140 lib/silcutil/silctask.[ch].
5142 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added SILC_UMODE_GONE mode to indicate when the client is not
5145 present in the SILC network. Added also support to the local
5146 command AWAY that will set this mode. Added support of showing
5147 "xxx is gone" in WHOIS command. The USERS command shows the
5148 gone status as well.
5150 * Fixed setting server and router operator privileges in the
5151 server's UMODE command. Affected file silcd/command.c.
5153 * Merged the SKE KE1 and KE2 payloads into one payload. The
5154 new KE payload is equivalent to the old KE2 payload.
5156 Cleaned up the SKE Start Payload parsing. It now uses the
5157 simple buffer unformatting to do the parsing. A lot faster
5160 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5161 to the SKE that is used to indicate whether both of the SKE
5162 parties should perform authentication. By default only the
5163 responder performs authentication. By setting this flag also
5164 the initiator must do authentication. By default it is unset
5165 since in normal SKE case, client to server connection, only
5166 the responder should do authentication. When doing SKE between
5167 two clients both should perform authentication. Updated the
5168 code and the protocol specs.
5170 * A little fix to IDENTIFY command in the server. Search the
5171 client first by hash not nickname. Affected file is
5174 * Fixed the silc_client_close_connection to support closing
5175 the client to client connections wihtout deleting too much
5176 data. Affected file lib/silcclient/client.c.
5178 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5179 are received if protocol used to be active but is not anymore
5180 the application would crash due to NULL pointer dereference.
5181 Affected files silcd/server.c and lib/silcclient/client.c.
5183 * Added `hash' field to the SilcClientConnection to include
5184 the hash function negotiated in the SKE protocol.
5186 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5187 to set the channel founder authentication data. A client can
5188 claim the founder rights later by providing the authentication
5189 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5190 This way the channel founder can regain the channel founder
5191 privileges even it is left the channel. This works only on
5192 local server and the client must be connected to the same
5193 server to be able to regain the founder rights. Updated the
5194 protocol specs accordingly.
5196 Added support to the CMODE command in the client to set the
5197 founder auth data. Read the README to see how to set it.
5199 Added support to the CUMODE command to claim the founder
5200 rights. Read the README to see how to do it.
5202 Added support for the founder authentication to the Channel
5203 Entry in the server. Affected file silcd/idlist.h.
5205 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5206 server's CMODE command. Affected file silcd/command.c.
5208 * Added the following new functions into lib/silccore/silcauth.[ch]:
5209 silc_auth_get_method and silc_auth_get_data.
5211 * The server now saves the remote hosts public key to the
5212 SilcIDListData pointer. Affected file silcd/protocol.c.
5214 * The normal server now does not remove the channel entry from
5215 the cache if the founder authentication data is set. It used
5216 to remove it if the founder was the last one on the channel on
5217 the server and left the channel. The auth data is saved and
5218 if the channel is re-joined later the old entry is used with
5219 the old auth data. Affected files silcd/command_reply.c and
5222 * Removed the `pkcs' field from the SilcIDListData structure
5223 in the server; it is not used. Affected file silcd/idlist.h.
5225 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Fixed packet processing on slow links. Partial packets were
5228 never re-processed because the incoming data buffer was cleared
5229 by the application. Application must not directly clear the
5230 sock->inbuf, the packet processing routines handle it. Fixed
5231 this in client library and in server.
5233 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Fixed the WHOIS and IDENTIFY send reply function to really
5236 check whether to send list or just one entry. Affected file
5239 * Cleaned up the LEAVE command's channel key distribution. The
5240 affected file silcd/command.c.
5242 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5243 can enforce the channel mode as well. In that case the ID
5244 includes the ID of the server. The code now enforces the
5245 mode change if the router have different mode than the server.
5247 * The notify client operation with CMODE_CHANGE notify can now
5248 return NULL client_entry pointer if the CMODE was not changed
5249 by client. Application must check for this.
5251 * Added <Server ID> argument to INFO command to support server
5252 info fetching by Server ID.
5254 * Added silc_server_announce_get_channel_users to get assembled
5255 packets of channel users of the specified channel. Affected
5256 file silcd/server.[ch].
5258 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5259 was freed underneath the ID Cache.
5261 * Re-announce clients when the server received CHANNEL_CHANGE
5262 notify from the router. Affected file silcd/packet_send.c.
5264 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5267 crashed since it did not handle the fact that there is no cipher
5268 called "3" and didn't check the error condition. Now fixed.
5270 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5271 flag. It can be used to send message requests.
5273 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Implemented the RESTART command in the client.
5277 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5278 notice type messages. Added notice printing to the user
5281 * The channel keys are not re-generated if the channel's mode
5282 is PRIVKEY, ie private key on the channel exists. Affected
5283 files silcd/server.c and silcd/command.c.
5285 * Fixed a little bug in channel message delivery when channel
5286 private keys are set in the server. Affected file is
5287 silcd/packet_send.c.
5289 * Changed the setting on channel->on_channel = TRUE from the
5290 silc_client_save_channel_key to the JOIN command reply. The
5291 key payload is not received if the private channel key is set.
5292 Affected file lib/silcclient/command_reply.c and the
5293 lib/silcclient/client_channel.c.
5295 * When the CMODE_CHANGE notify is sent and the channel private
5296 key mode is removed the channel key must be re-generated in
5297 other cells as well. Added this support for the router in the
5298 silcd/packet_receive.c.
5300 * Added new local command NOTICE to send notice message on
5301 channel. Affected file silc/local_command.[ch].
5303 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Added new local command ME to the client. It is used to send
5306 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5307 some action. Affected file silc/local_command.[ch].
5309 * Changed channel_message and private_message client operations
5310 to deliver the message flags to the application. Added also
5311 the `flags' arguments to the silc_client_send_channel_message
5312 and silc_client_send_private_message functions. Affected file
5315 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * Redefined the Private Message Payload to support private message
5318 keys and to support the new private message flags. Updated
5319 the protocol specs. Flags makes it possible to have for example
5320 CTCP style messages.
5322 * Added new type SilcPrivateMessagePayload and defined an API
5323 for it in the lib/silcclient/silcprivate.[ch].
5325 * Tested private message private keys successfully. Tested the
5326 private message key set, unset and list commands with the new
5329 * Redefined the Channel Message Payload to include the channel
5330 message flags (equal with private message flags) to support
5331 for example CTCP style messages.
5333 * Defined some of the message (for channel and private message)
5334 flags. Updated the protocol specs and added the flags to the
5335 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5337 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Added SilcKeyAgreementStatus type to the key agreement routines
5340 to indicate the current status and error if one occured.
5341 The status types are defined in the lib/silcclient/silcapi.h.
5343 * Added new local command KEY that is used to set and unset private
5344 keys for channels, set and unset private keys for private messages
5345 with remote clients and to send key agreement requests and
5346 negotiate the key agreement protocol with remote client. The
5347 key agreement is supported only to negotiate private message keys,
5348 it currently cannot be used to negotiate private keys for channels,
5349 as it is not convenient for that purpose.
5351 * Fixed a minor pending callback setting bug in the function
5352 silc_client_get_client_by_id_resolve, now the function works.
5353 Affected file lib/silcclient/idlist.c.
5355 * Added function silc_net_get_local_port to get local bound
5356 port by socket. Added to lib/silcutil/silcnet.[ch].
5358 * Added `sockets' and `sockets_count' fields to the SilcClient
5359 object. They hold the sockets of the listenning sockets in
5360 the client. Listenning sockets may be for example the key
5361 agreement server. Affected file lib/silcclient/client.[ch].
5362 Added functions the silc_client_add_socket and the
5363 silc_client_del_socket. They are exported to the application
5366 * Added ~./silc/clientkeys to support other client's public keys.
5368 * Renamed verify_server_key client operation to verify_public_key
5369 and added one argument to indicate the type of the connection
5370 (server, client etc.).
5372 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added silc_server_connection_auth_request to handle the
5375 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5376 silcd/packet_receive.[ch].
5378 * Added silc_server_send_connection_auth_request into the
5379 silcd/packet_send.c to send the connection auth request packet.
5381 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5384 * Fixed the public key authentication in responder side in the
5385 server. The `auth_data' pointer includes the SilcPublicKey
5386 not the path to the public key. Affected file silcd/protocol.c.
5388 * Implemented the public key authentication in the initiator side
5389 in the server. Affected file silcd/protocol.c.
5391 * Removed the [RedirectClient] config section from the server
5392 configuration. Is not needed and I don't want to implement it.
5394 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Cleaned up the CMODE command in the server. It now works
5397 correctly and supports all the modes defined in the protocol.
5398 Affected file is silcd/command.c.
5400 * Added `hmac_name' field to the SilcChannelEntry in the server
5401 to hold the default HMAC of the channel. It can be set when
5402 creating the channel (with JOIN command). Affected files
5405 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5406 type to indicate the change of the current cipher and hmac
5407 on the channel. Client can safely ignore the <cipher> argument
5408 (if it chooses to do so) since the CHANNEL_KEY packet will
5409 force the channel key change anyway. The <hmac> argument is
5410 important since the client is responsible of setting the new
5411 HMAC and the hmac key into use.
5413 * Fixed the CMODE command in the client library as well.
5415 * Tested CMODE command in router environment successfully.
5417 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Show the version of the remote client (or server) when connecting
5420 to the server. It is logged to the log file. Affected file
5421 is silcd/protocol.c.
5423 * Fixed the KILLED notify handling in the client library. The
5424 client must be removed from all channels when receiving the
5427 Also, do not remove the client entry when giving the KILL
5428 command but when the KILLED notify is received.
5430 * Removed silc_idlist_find_client_by_nickname from the server.
5431 Not needed anymore. Affected files silcd/idlist.[ch].
5433 * Implemented the CHANNEL_CHANGE notify type handling to the
5434 server. Affected file silcd/server.c.
5438 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Added silc_server_send_notify_invite to send the INVITE
5441 notify between routers.
5443 * Implemented the INVITE command correctly to the server.
5445 * Implemented the INVITE notify type handling in the server.
5447 * Implemented the INVITE command to the client library and on the
5450 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added function silc_server_get_client_resolve to find the
5453 client entry by ID from all ID lists and then resolve it
5454 (using WHOIS) if it cannot be found. Affected file is
5457 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Implemented the BAN command to the client library.
5461 * The JOIN command in the server now checks the invite list
5464 * Changed the silc_command_reply_payload_encode_va and the
5465 silc_command_payload_encode_va to support that if argument is
5466 NULL it ignores and checks the next argument. Affected file
5467 lib/silccore/silccommand.c.
5469 * Added silc_server_send_notify_ban to send the BAN notify
5470 type between routers.
5472 * Chaned the silc_notify_payload_encode to support that if
5473 argument is NULL it ignores and checks the next argument.
5474 Affected file lib/silccore/silcnotify.c.
5476 * Tested ban lists in router environment successfully.
5478 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Implemented BAN command to the server, in silcd/command.[ch].
5482 * Removed the BAN and INVITE_LIST modes from the CMODE command
5485 * Added function silc_string_match to regex match two strings.
5486 Affected files lib/silcutil/silcutil.[ch].
5488 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Redefined parts of the SilcChannelEntry in the server to support
5491 the new ban and invite lists.
5493 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Redefined the INVITE command. The same command can be used to
5496 invite individuals to the channel but also to manage the invite
5497 list of the channel (to add to and remove from the invite list).
5498 Updated the protocol specs.
5500 * Added new command SILC_COMMAND_BAN that can be used to manage
5501 the ban list of the channel. Updated the protocol specs.
5503 * Removed the channel modes: the SILC_CMODE_BAN and the
5504 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5505 in the CMODE command. The equivalent features are now available
5506 using INVITE and BAN commands. Updated the protocol specs.
5508 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5509 in the network about change in the current ban list. The notify
5510 type is not used by the client.
5512 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5513 support the invite lists.
5515 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Added new function silc_string_regexify that converts string
5518 including wildcard characters into regex string that can
5519 be used by the GNU regex library. Added into the file
5520 lib/silcutil/silcutil.[ch].
5522 Added silc_string_regex_combine to combine to regex strings
5523 into one so that they can be used as one regex string by
5524 the GNU regex library. Added into the file
5525 lib/silcutil/silcutil.[ch].
5527 Added silc_string_regex_match to match two strings. It returns
5528 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5530 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Imported GNU regex to the soruce tree into lib/contrib.
5533 Fixed some compiler warning from the regex.c.
5535 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Fixed MOTD command in the server to work in router environment.
5539 * Fixed the MOTD command in the client library to support
5540 the server argument in the command.
5542 * Added `nickname_len' argument to the silc_idlist_add_client
5543 in the server, as the `nickname' argument may be binary data
5546 * Added silc_idlist_get_channels to return all channels from
5549 * Implemented LIST command to the server. Affected file is
5552 * Implemented the LIST command to the client library and on the
5555 * Added [<user count>] argument to the LIST command reply.
5556 With private channels the user count is not shown.
5558 * Updated TODO and README.
5560 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * The client entry's data.registered must be TRUE even with
5563 global client entry on global client list. The data.registered
5564 is used to check whether the client is anymore in the network,
5565 for example with WHOWAS command so it must be valid.
5567 * Fixed the WHOWAS command in the server. It now actually works
5568 in router environment. Added function into silcd/command_reply.c
5569 silc_server_command_reply_whowas_save.
5571 * Added silc_idlist_purge function to the silcd/idlist.c
5572 to periodically purge the ID Cache.
5574 * Fixed INFO command in the server. It works now in router
5575 environment. Added <server name> argument to the INFO command
5576 reply. Updated the protocol specs.
5578 * Fixed minor bug in silc_idcache_purge to not purge if the
5579 expire value is zero.
5581 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5582 they were buggy because of the WHOWAS information.
5584 * Fixed local command MSG to handle the async resolving of
5585 the remote client properly. It used to fail the first MSG.
5586 Affected file silc/local_command.c.
5588 * Added `data_len' field to SilcIDCache context.
5590 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Update TODO. Todo in commands in the server.
5594 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5597 used by routers as broadcast packet to inform other routers
5598 about the changed user mode.
5600 Implemented the notify handling in the server. Affected file is
5601 silcd/packet_receive.c. Added the function
5602 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5604 * Added new generic Channel Payload and deprecated the New Channel
5605 Payload. The New Channel Payload is now the generic Channel
5608 * Added new argument `mode' to the silc_server_send_new_channel
5609 as it is required in the Channel Payload now.
5611 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5612 and created a new and real SilChannelPayload to represent the
5613 new generic Channel Payload. Implemented the encode/decode
5614 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5616 * Added silc_server_get_client_channel_list to return the list
5617 of channels the client has joined for WHOIS command reply.
5618 Affected file silcd/server.[ch].
5620 * Implemented the channel list sending in the WHOIS command reply
5621 in server and in the client.
5623 Implemented the channel list displaying on the user interface
5624 as well. Affected file silc/client_ops.c.
5626 * Added silc_channel_payload_parse_list to parse list of Channel
5627 Payloads. It returns SilcDList list of SilcChannelPayloads.
5628 Client for example can use this function to parse the list of
5629 channels it receives in the WHOIS command reply. The caller
5630 must free the list by calling silc_channel_payload_list_free.
5631 Affected files lib/silccore/silcchannel.[ch].
5633 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Added one new argument <user mode> to the WHOIS command reply
5636 to return the mode of the user in SILC. Updated the protocol
5639 Implemented it to the server and client.
5641 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Fixed the mode printing on the user interface on joining.
5644 Affected file silc/client_ops.c.
5646 * Implemented the UMODE command and user modes in general to the
5647 client library and to the user interface.
5649 * Implemented the UMODE command to the server.
5651 * The server now sends UNKNOWN_COMMAND error status if client sends
5652 unknown command. Affected file silcd/command.c.
5654 * All server commands now handle the command identifier the right
5655 way when sending the command reply to the client. The client can
5656 use to identify the command replies with the identifier.
5658 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Added silc_server_get_client_route to resolve the route to
5661 the client indicated by the client ID. Affected file is
5664 * Added silc_server_relay_packet as general function to relay
5665 packet to arbitrary destination. This deprecates functions
5666 like _send_private_message_key, _relay_notify etc. Affected
5667 file is silcd/packet_send.[ch].
5669 Removed silc_server_send_key_agreement,
5670 silc_server_send_private_message_key and
5671 silc_server_packet_relay_notify functions from the file
5672 silcd/packet_send.[ch].
5676 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5677 server. Affected file silcd/packet_receive.[ch].
5679 * Implemented the KILL command to the client. Implemented the
5680 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5681 Affected files lib/silcclient/command[_reply].c and
5682 lib/silcclient/client_notify.c. Implemented the KILL notify
5683 printing in the user inteface.
5685 * Fixed a lot silc_parse_nick memory leaks from the client
5686 library in the file lib/silcclient/command.c.
5688 * Changed the silc_server_send_notify_on_channels's `sender'
5689 argument from SilcSocketConnection to SilcClientEntry to
5690 check the sender as entry and not as connection object and not
5691 to send to the client provided as argument. The affected file
5692 is silcd/packet_send.[ch].
5694 * The notify packets that are destined directly to the client used
5695 to not to be processed by the server. Now changed that and the
5696 server processes all notify packets. After relaying the packet
5697 to the client the notify packet is processed in the server.
5699 * The silc_server_free_client_data now checks whether there is
5700 pending outgoing traffic for the client and purges the data to
5701 the network before removing the client entry.
5703 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5706 an client is killed from the SILC Network. Updated the protocol
5709 Added new function silc_server_send_notify_killed to the
5710 silcd/packet_send.[ch].
5712 * Added function silc_server_packet_relay_notify to relay notify
5713 packets that are destined directly to a client. In this case
5714 the server does not process the notify packets but merely relays
5715 it to the client. Affected file silcd/packet_send.[ch].
5717 Added also silc_server_packet_process_relay_notify to check
5718 whereto relay the notify. Affected file is
5719 silcd/packet_receive.[ch].
5721 * Implemented the KILL command to the server.
5725 * Added the backup schema desgined last fall to the protocol
5726 specs for everyone to see. The specification is in the
5727 *-spec-xx.txt draft and the packet type definitions for the
5728 backup routers is in *-pp-xx.txt draft. Thusly, added also
5729 new packet type SILC_PACKET_CELL_ROUTERS.
5731 * A big security problem in the implementation discovered. The
5732 signoff of an client did not cause new channel key generation
5733 which it of course should've done. The channel keys must be
5734 always re-generated when client leaves (or signoffs) the channel.
5735 The silc_server_remove_from_channels funtion now handles
5736 the channel key re-generation.
5738 * Added `sender' argument to the silc_server_send_notify_on_channels
5739 to not to send the client provided as argument. Affected file
5740 silcd/packet_send.[ch].
5742 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Implemented OPER and SILCOPER commands into the server and
5747 * Added silc_auth_verify and silc_auth_verify_data to verify
5748 the authentication directly from the authentication payload.
5749 It supports verifying both passphrase and public key based
5750 authentication. Affected file lib/silccore/silcauth.[ch].
5752 * Added `hash' field to the SilcIDListData structure. It is the
5753 hash negotiated in the SKE protocol. Affected file is
5756 * Slight redesigning of the SilcAuthPayload handling routines.
5757 Do not send SilcPKCS but SilcPublicKey as argument.
5759 * Implemented the public key authentication support to the
5760 serverconfig. The public key is loaded from the provided path
5761 and saved as authentication data to void * pointer. Thus,
5762 changed the unsigned char *auth_data to void *auth_data;
5764 * Fixed SHUTDOWN command to send the reply before the server
5765 is shutdown. :) Affected file silcd/command.c.
5767 * Fixed fatal bug in CONNECT command. The hostname was invalid
5768 memory and server crashed. Affected file silcd/command.c.
5770 * Fixed fatal bug in CLOSE command. The server_entry became
5771 invalid but was referenced later in the command. Affected file
5774 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Fixed fatal bug in failure packet handling. Server ignored
5777 the failure and thus crashed when it came.
5781 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5784 that the command may be executed only once in (about) 2 seconds.
5785 The old SILC_CF_LAG flag is same but allows command bursts up
5786 to five before limiting.
5788 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5789 server code. Various commands now includes the CF_LAG_STRICT
5790 flag to disallow any kind of miss-use of the command.
5792 * Fixed the silc_buffer_unformat to not to allocate any data
5793 if the length of the data is zero. It used to allocate the
5794 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5796 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * Changed the format of AdminConnection configuration section
5799 in the server. Added username of the admin to the format.
5800 Affected files silcd/serverconfig.[ch].
5802 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5803 to return admin configuration data by host, username and/or
5806 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Implemented WHOWAS command to the server. Added the functions:
5810 silc_server_command_whowas_parse,
5811 silc_server_command_whowas_send_reply,
5812 silc_server_command_whowas_from_client and
5813 silc_server_command_whowas_from_server
5815 * Added <Client ID> argument to the WHOWAS command reply. Updated
5816 the protocol specs accordingly.
5818 * Implemented WHOWAS command and command_reply to the client
5821 Implemented the WHOWAS printing on the user interface.
5823 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Added new argument to the WHOWAS command reply, the real name.
5826 It is an optional argument. Updated the protocol specs.
5828 * Added SilcIDCacheDestructor callback that is registered when
5829 the SilcIDCache is allocated. The callback is called when
5830 an cache entry in the ID Cache expires, or is purged from the
5831 cache. Added into lib/silccore/idcache.[ch].
5833 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5834 to destruct the client entries when the cache entry expires.
5835 Other ID Cache's in server and in the client library ignores
5838 * If the ID Cache entry's `expire' field is zero then the entry
5839 never expires. Added boolean `expire' argument to the
5840 silc_idcache_add function in the lib/silccore/idcache.[ch].
5841 If it is TRUE the default expiry value is used.
5843 * Added silc_server_free_client_data_timeout that is registered
5844 when client disconnects. By default for 5 minutes we preserve
5845 the client entry for history - for WHOWAS command.
5847 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Added support to the server to enforce that commands are not
5850 executed more than once in 2 seconds. If server receives
5851 commands from client more frequently, timeout is registered
5852 to process the commands. Affected file silcd/command.c.
5853 Added new function silc_server_command_process_timeout.
5855 * Changed NICK_NOTIFY handling in client library to check that
5856 if the client's nickname was changed, so there is no need to
5857 resolve anything from the server.
5859 * Removed error printing from the WHOIS and IDENTIFY commands.
5860 If error occurs then it is ignored silently in the client library.
5861 The application, however, may map the received error to
5862 human readable error string. The application currently maps
5863 the NO_SUCH_NICKNAME error to string.
5865 * Made the command status message public to the application. Moved
5866 them from lib/silcclient/command_reply.c to
5867 lib/silcclient/command_reply.h. The application can map the
5868 received command status to the string with the
5869 silc_client_command_status_message function.
5871 * Added check to the server to check that client's ID is same
5872 as the Source ID in the packet the client sent. They must
5875 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Added dist-bzip hook to the Makefile.am to make bzip2
5878 compressed distributions.
5880 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Server now enforces the maximum length for the nickname and
5883 the channel as protocol specification dictates. 128 bytes for
5884 nickname and 256 bytes for channel name.
5886 * Moved the WHOIS printing to the application. The client libary
5887 does not print out the WHOIS information anymore, the application
5888 must do it. Renamed silc_client_command_reply_whois_print to
5889 the silc_client_command_reply_whois_save.
5891 The client's idle time is also sent to the application now, and
5892 the idle is shown on screen.
5894 * Added silc_client_command_reply_identify_save to save the
5895 received IDENTIFY entries.
5897 * Do not check for channel private keys in message sending and
5898 reception if the channel does not have the PRIVKEY mode set.
5899 Affected file lib/silclient/client_channel.c.
5901 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5904 just surfaced after chaning the JOIN procedure.
5906 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Added silc_client_get_clients_by_list to get client entries
5909 from Client ID list, that is returned for example by JOIN
5910 and USERS command replies. The application should use this
5911 function for example when JOIN command reply is received to
5912 resolve the clients already on the channel (library does not
5913 do that anymore as USERS command reply is not used in the JOIN
5914 procedure anymore). Affected files lib/silcclient/silcapi.h and
5915 lib/silcclient/idlist.c.
5917 * JOIN command reply and USERS command reply returns now SilcBuffer
5918 pointers instead of unsigned char pointers when returning
5919 the client list and mode list.
5921 * Added <Client ID> argument to the JOIN command reply, mainly
5922 for the server to identify for which client the command was
5923 originally sent. Updated protocol specs accordingly.
5925 * Added SilcDlist private_key pointer to the SilcChannelEntry
5926 in the client to support the channel private keys. Affected
5927 file is lib/silcclient/idlist.h.
5929 * Added SilcChannelPrivateKey argument to the function
5930 silc_client_send_channel_message so that application can choose
5931 to use specific private ke if it wants to. If it is not provided,
5932 the normal channel key is used, unless private keys are set.
5933 In this case the first (key that was added first) is used
5934 as the encryption key.
5936 * Implemented the support for channel private key handling.
5937 Implemented the following functions:
5939 silc_client_add_channel_private_key,
5940 silc_client_del_channel_private_keys,
5941 silc_client_del_channel_private_key,
5942 silc_client_list_channel_private_keys and
5943 silc_client_free_channel_private_keys
5945 Affected file lib/silcclient/client_channel.c.
5947 * Added the support for the private keys in the channel message
5948 sending and encryption and in the message reception and
5949 decryption. Affected funtions are
5950 silc_client_send_channel_message and silc_client_channel_message.
5952 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added SKE's key verify callback to the client library's
5955 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5957 * Removed the statement that server (or router) must send USERS
5958 command reply when joining to the channel so that the client
5959 knows who are on the channel. Instead, the client list and
5960 client's mode list is now sent in the JOIN command reply to the
5961 client who joined channel. This is better solution.
5963 * Added function silc_server_get_users_on_channel and function
5964 silc_server_save_users_on_channel to the silcd/server.[ch].
5966 * Removed function silc_server_command_send_users from the
5969 * Do not show topic on the client library anymore. The topic is
5970 sent in the command reply notify to the application and the
5971 application must show the topic now.
5973 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Added client searching by nickname hash into the IDENTIFY and
5976 WHOIS commands in the server as they were clearly missing from
5977 them. Affected file is silcd/command.c.
5979 * Fixed a bug in private message receiving in the client library.
5980 The remote ID was freed and it wasn't supposed, now it is
5983 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Minor fix to the channel payload; allocate the data area, as it
5986 needs to be of specific length.
5988 * If the key agreement port is zero then the operating
5989 system will define the bound port. Affected files are
5990 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5992 * Added new function silc_channel_payload_decrypt into the file
5993 lib/silccore/silcchannel.[ch].
5995 * Moved the channel message etc, check from silc_packet_decrypt
5996 to applications. The library calls now a generic
5997 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5998 when the packet is either normal or special. This was done to
5999 allow more wide range of checking that was not allowed when
6000 the code was in library. Now applications can do virtually any
6001 checks to the packet and return to the library the decision how
6002 the packet should be processed. Affected files are
6003 lib/silccore/silcpacket.[ch].
6005 Added silc_server_packet_decrypt_check to the server and
6006 silc_client_packet_decrypt_check to the client library.
6008 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6009 to send with specified source and destination information.
6011 * Channel message delivery between routers was broken after the
6012 channel key distribution was fixed earlier. The channel key
6013 was used be to distributed to other routers as well which is not
6014 allowed by the protocol. Now this is fixed and channel keys
6015 really are cell specific and the channel message delivery between
6016 routers comply with the protocol specification.
6018 * Fixed various commands in server to check also the global list
6019 for the channel entry and not just the local list. The affected
6020 file silcd/command.c.
6022 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Added assert()s to buffer formatting and unformatting routines
6025 to assert (if --enable-debug) when error occurs. Affected
6026 file: lib/silcutil/silcbuffmt.c.
6028 * Changed to auto-reconnect to check whether the remote host is
6029 router and register the re-connect timeout if it is. It used
6030 to check that whether we are normal server, but router must do
6031 auto-reconnect with another router as well. Affected file
6034 * Removed the [<key len>] option from CMODE command as the cipher
6035 name decides the key length, nowadays. See the defined ciphers
6036 from the protocol specification.
6038 * Added [<hmac>] option to the CMODE command to define the HMAC
6039 for the channel. Added SILC_CMODE_HMAC channel mode.
6041 * Added [<hmac>] option for the JOIN command so that user can
6042 select which HMAC is used to compute the MACs of the channel
6045 * Added Hmac field to the Channel Message Payload. The integrity
6046 of plaintext channel messages are now protected by computing
6047 MAC of the message and attaching the MAC to the payload. The
6048 MAC is encrypted. Now, it is clear that this causes some
6049 overhead to the size of the packet but rationale for this is that
6050 now the receiver can verify whether the channel message decrypted
6051 correctly and also when private keys are set for the channel the
6052 receiver can decrypt the packet with several keys and check from
6053 the MAC which key decrypted the message correctly.
6055 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6056 lib/silccrypt/silccipher.[ch].
6058 * Added silc_hash_len to return the digest length into the
6059 lib/silcrypt/silchash.[ch].
6061 * Rewrote parts of Silc Channel Payload interface in the
6062 lib/silccore/silcchannel.[ch]. The encode function now also
6063 encrypts the packet and parse function decrypts it.
6065 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Fixed a minor formatting bug in the SKE's key material processing.
6068 It actually might have processed the keys wrong way resulting
6071 * Redefined the mandatory HMAC algorithms and added new algorithms.
6072 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6073 and hmac-md5 truncated to 96 bits. The mandatory is now
6074 hmac-sha1-96. Rest are optional (including the one that used
6075 to be mandatory). Rationale for this is that the truncated HMAC
6076 length is sufficient from security point of view and can actually
6077 make the attack against the HMAC harder. Also, the truncated
6078 HMAC causes less overhead to the packets. See the RFC2104 for
6081 * Added new [hmac] configuration section. The SKE used to use
6082 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6083 is of course wrong. The official names that must be proposed in
6084 the SKE are the ones defined in the protocol specification
6085 (hmac-sha1-96 for example). The user can configure any hmac
6086 using any hash function configured in the [hash] section. At
6087 least, the mandatory must be configured.
6089 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6091 * Added HMAC list to the SKE proposal list. It has now both
6092 hash algorithm list and HMAC list. This makes the protocol
6093 incompatible with previous versions. The SKE now seems to work
6094 the way it is supposed to work, for the first time actually.
6096 * Defined plain Hash algorithms to the protocol specification.
6099 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Implemented support for key agreement packets into the server.
6102 Added functions silc_server_key_agreement and
6103 silc_server_send_key_agreement. Other than these functions,
6104 server has nothing to do with this packet.
6106 * Added support for private message key packets into the server.
6107 Added functions silc_server_private_message_key and
6108 silc_server_send_private_message_key.
6112 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6113 called in the protocol's final callback instead in the END
6114 protocol state. This makes a little more sense and in the same
6115 time in client we can use the same protocol routines for normal
6116 key exchange and to key agreement packet handling as well.
6118 * Added to both client's and server's KE protocol context the
6119 SilcSKEKeyMaterial pointer to save the key material. We will
6120 bring the key material to the protocol's final callback by doing
6121 this. The final callback must free the key material.
6123 * Added SKE's packet_send callback into client's KE protocol
6124 context so that the caller can choose what packet sending function
6125 is used. This way we can use different packet sending when
6126 doing normal SKE when doing key agreement packet handling (in
6127 the key agreement packet handling we do not want to encrypt
6130 * Implemented the responder side of the key agreement routines
6131 in the client. The client can now bind to specified port and
6132 accept incoming key negotiation. The key material is passed
6133 to the application after the protocol is over.
6135 * Implemented the processing of incoming Key Agreement packet
6136 in the client. Added function silc_client_key_agreement to
6139 * Implemented the intiator side of the key agreement routines
6140 in the client. The client can now initiate key agreement with
6141 another remote client. The key material is passed to the
6142 application after the protocol is over.
6144 * Created client_keyagr.c to include all the key agreement
6147 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6148 SILC_TASK_CALLBACK except that it is not static.
6150 * Created client_notify.c and moved the Notify packet handling
6151 from the client.[ch] into that file.
6153 * Created client_prvmsg.c and moved all private message and
6154 private message key routines from the client.[ch] into that file.
6156 * Create client_channel.c and moved all channel message and
6157 channel private key routines from the client.[ch] into that file.
6159 * Changed silc_client_get_client_by_id_resolve to resolve with
6160 WHOIS command instead of IDENTIFY command, in the file
6161 lib/silclient/idlist.c.
6163 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Implemented the SKE's responder side to the Client library.
6167 * When FAILURE is received to the protocol do not trust it
6168 blindly. Register a timeout to wait whether the remote closes
6169 the connection as it should do it, only after that process the
6170 actual failure. This was changed to both client and server.
6172 * Added client_internal.h to include some of the structures
6173 there instead of client.h in lib/silcclient/.
6175 * Added function silc_task_unregister_by_callback to unregister
6176 timeouts by the callback function.
6178 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Some "Incomplete WHOIS info" errors has been appearing on the
6181 log files. Took away the entry->userinfo check from WHOIS
6182 reply sending. The entry->userinfo is now " " if client did not
6183 provide one. I thought this was fixed earlier but something
6184 is wrong still. Let's see if the error still appears.
6186 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Fixed a minor bug in the login when the channel key is
6189 re-generated in the server. It used to generate the key in
6190 wrong order and thus caused problems in the channel traffic.
6192 * Fixed a minor bug in channel key distsribution after
6193 KICK command. The key was not sent to the router even though
6196 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Added silc_ske_process_key_material_data as generic routine
6199 to process any key material as the SILC protocol dictates. The
6200 function is used by the actual SKE library but can be used by
6201 applications as well. This relates to the private message keys
6202 and the channel private keys since they must be processed the
6203 same way the normal SILC session keys. The protocol dictates
6204 this. Affected files: lib/silcske/silcske.[ch].
6206 Added also silc_ske_free_key_material to free the
6207 SilcSKEKeyMaterial structure.
6209 * Defined silc_cipher_set_key function to set the key for
6210 cipher without using the object's method function. The affected
6211 files: lib/silccrypt/silccipher.[ch].
6213 * Implemented silc silc_client_add_private_message_key,
6214 silc_client_add_private_message_key_ske,
6215 silc_client_del_private_message_key,
6216 silc_client_list_private_message_keys and
6217 silc_client_free_private_message_keys functions in the
6220 Added functions silc_client_send_private_message_key to send
6221 the Private Message Key payload and silc_client_private_message_key
6222 to handle incoming Private Message Key payload.
6224 * Added Cipher field to the Private Message Key payload to set
6225 the cipher to be used. If ignored, the default cipher defined
6226 in the SILC protocol (aes-256-cbc) is used.
6228 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Removed lib/silcclient/ops.h file.
6232 Redefined parts of the SILC Client Library API. Created new
6233 file silcapi.h that deprecates the ops.h file and defines the
6234 published Client Library API. Defined also private message key
6235 API and channel private key API into the file.
6237 This is the file that the application must include from the
6238 SILC Client Library. Other files need not be included by
6239 the application anymore.
6241 * Added new key_agreement client operation callback and also
6242 defined the Key Agreement library API for the application.
6244 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6247 is used by clients to request key negotiation between another
6248 client in the SILC network. If the negotiation is started it
6249 is performed using the SKE protocol. The result of the
6250 negotiation, the secret key material, can be used for example
6251 as private message key.
6253 Implemented the Key Agreement payload into the files
6254 lib/silccore/silauth.[ch].
6256 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Redefined ciphers for the SILC protocol. Added some new ciphers
6259 and defined the key lengths for the algorithms. Changed the
6260 code accordingly. The default key length is now 256 bits.
6262 * Fixed SKE key distribution function silc_ske_process_key_material
6263 when the key length is more than 128 bits. The default key
6264 length in SILC is now 256 bits.
6266 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6267 to indicate unsupported algorithm.
6269 * Renamed rijndael.c to aes.c and all functions as well.
6271 * Fixed a long standing channel key setting bug in client library.
6272 Weird that it has never surfaced before.
6274 * Fixed bug in channel deletion. If the entire channel is removed
6275 then it must also delete the references of the channel entry
6276 from the client's channel list as the client's channel entry and
6277 the channel's client entry share same memory.
6279 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Implemented CONNECT and SHUTDOWN commands in the client.
6283 * Implemented CLOSE command to the client.
6285 * Added the function silc_idlist_find_server_by_name into the
6286 files silcd/idlist.[ch].
6288 Added the function silc_idlist_find_server_by_conn into the
6289 files silcd/idlist.[ch].
6291 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * DIE command was renamed to SHUTDOWN. Updated the both code
6296 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6297 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6299 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6302 * Added function silc_server_create_connection function to create
6303 connection to remote router. My server implementation actually
6304 does not allow router to connect to normal server (it expects
6305 that normal server always initiates the connection to the router)
6306 so the CONNECT command is only good for connecting to another
6309 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6312 or some other client was kicked from the channel.
6314 Implemented the handling of the notify type to both client
6317 Implemented silc_server_send_notify_kicked to send the KICKED
6318 notify. It is used to send it to the server's primary router.
6320 * Implemented the KICK command into server and client.
6322 * Added `query' argument to the silc_idlist_get_client function
6323 to indicate whether to query the client from server or not if
6326 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6327 to indicate that the client is not channel founder.
6331 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Removed the rng context from SilcPacketContext structure and
6334 changed that the packet routine uses the Global RNG API.
6336 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Added support for quit message that client can "leave" on the
6339 channel when it quits the SILC. It is ditributed inside the
6340 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6342 Added silc_server_free_client_data that will take the
6343 signoff message as argument.
6345 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6347 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Updated parts of the protocol specification to keep it up
6352 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6355 payloads in one packet.
6357 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6358 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6359 use now the new List flag.
6361 * Also deprecated the following packet types: REPLACE_ID,
6362 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6364 * Added list support for Notify packet in server.
6366 * Added silc_server_send_notify_channel_change to send the
6367 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6368 the silc_server_send_replace_id.
6370 * Added silc_server_send_notify_nick_change to send the
6371 NICK_CHANGE notify type. Deprecates the function
6372 silc_server_send_replace_id.
6374 * Added silc_server_send_notify_join to send the JOIN notify type.
6375 Deprecates the function silc_server_send_new_channel_user.
6377 * Added silc_server_send_notify_leave to send LEAVE notify type.
6378 Deprecates the function silc_server_send_remove_channel_user.
6380 * Added silc_server_send_notify_cmode and
6381 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6382 types. Deprecates the silc_server_send_set_mode function.
6384 * Added SERVER_SIGNOFF notify type to indicate that server has
6385 quit. This means that all clients on the channel from that
6386 server will drop. This can be also used when netsplit happens.
6388 Deprecated REMOVE_ID packet type since it is not needed anymore
6391 Added silc_server_send_notify_server_signoff to send the
6392 SERVER_SIGNOFF notify type. Deprecates the function
6393 silc_server_send_remove_id.
6395 Added also silc_server_send_notify_signoff to send the
6396 SIGNOFF notify type.
6398 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6399 SILC protocol from this day on. Changed the protocol
6400 specification as well.
6402 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6403 notify type. It is used between routers to notify about
6404 topic changes on a channel.
6406 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6409 * Partly updated the protocol specification to comply with the
6410 changes now made. It is still though a bit outdated.
6412 * The JOIN notify type now takes one extra argument <Channel ID>.
6413 The packet used to be destined to the channel but now the
6414 JOIN type may be sent as list thus it is impossible to
6415 destine it to any specific channel. By adding this argument
6416 it is again possible.
6418 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Added CREDITS file. The CHANGES and CREDITS file will appear
6421 in the distribution as well.
6423 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6426 types in the server's silcd/packet_receive.c.
6428 * Implemented CMODE and CUMODE to work in router environment.
6430 * Fixed minor encoding and decoding buglet from the
6431 lib/silccore/silcmode.c.
6433 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6436 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6438 * Changed all SilcConfigServer* and silc_config_server* to
6439 SilcServerConfig* and silc_server_config*, respectively.
6442 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Associated the ID (client or server ID) to the Authentication
6445 Payload to avoid any possibility of forging. Updated the
6446 protocol specification and the code accordingly.
6448 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * The RSA key length is now save to the RsaKey context in the
6451 key generation process in lib/silccrypt/rsa.c. The key length
6452 is now used to figure out the maximum size of the block allowed
6453 to be encrypted/signed.
6455 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6456 is equivalent to the silc_mp_mp2bin but does not allocate any
6459 * Changed silc_mp_mp2bin API to take length argument. If it is
6460 non-zero then the buffer is allocated that large. If zero, then
6461 the size is approximated using silc_mp_sizeinbase, which however
6464 * Created Global RNG API which is global RNG that application can
6465 initialize. After initializing, any routine anywhere in the
6466 code (including library) can use RNG without allocating a new
6467 RNG object. This was done to allow this sort of use of the
6468 RNG in code that has no chance to allocate RNG object. All
6469 applications currently allocate this and many routines in the
6470 library use this. Affected file lib/silccrypt/silcrng.[ch].
6472 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6473 it to use the Global RNG API.
6475 * Defined Authentication Payload into protocol specification that
6476 is used during SILC session to authenticate entities. It is
6477 used for example by client to authenticate itself to the server
6478 to obtain server operator privileges.
6480 Implemented this payload into the lib/silccore/silcauth.[ch].
6481 Implemented also routines for public key based authentication
6482 as the new protocol specification dictates.
6484 Moved definitions of different authentication methods from
6485 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6487 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6488 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6489 silc_pkcs_verify_with_hash functions into the file
6490 lib/silccrypt/silcpkcs.[ch].
6492 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * The client entry's userinfo pointer must be always valid.
6495 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6496 will fail since it requires the userinfo. Now, the userinfo
6497 is allocated as "" if actual userinfo does not exist. Actually,
6498 it must exist and it is totally Ok to drop client connections
6499 that does not announce the userinfo. However, we will make
6500 this workaround for now.
6502 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6503 to return the remote port by socket.
6505 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6508 SILC_SERVER_PENDING_EXEC and added an new macro
6509 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6510 data or when error occurs while processing the pending command.
6512 Added new argument `destructor' into silc_server_command_pending
6513 and to the SilcServerCommandPending object. This destructor is
6514 now called after calling the pending callback or if error occurs
6515 immediately. If error occurs the actual pending callback won't
6516 be called at all - only the destructor. The destructor may be
6517 NULL if destructor is not needed.
6519 All this applies for client library code as well. Similar
6520 changes were made there as well for the pending commands.
6522 In the client, the application must now allocate the
6523 SilcClientCommandContext with the silc_client_command_alloc
6526 * Added reference counter to the SilcServerCommandContext. Added
6527 function silc_server_command_alloc and silc_server_command_dup
6530 Same type of functions added to the client library for the same
6533 * Removed the cmd_ident from IDListData away since it is now
6534 global for all connections. It is the command identifier used
6535 in command sending and with pending commands. The affected file
6538 * Added reference counter to the SilcSocketConnection objecet to
6539 indicate the usage count of the object. The object won't be
6540 freed untill the reference counter hits zero. Currently only
6541 server uses this, and client ignores it. The client must be
6542 set to use this too later. The affected files are
6543 lib/silccore/silcsockconn.[ch]. Added also the function
6544 silc_socket_dup to increase the reference counter.
6546 This was mainly added because it is possible that the socket
6547 is removed underneath of pending command or other async
6548 operation. Now it won't be free'd and proper DISCONNECTING
6549 flags, etc. can be set to avoid sending data to connection that
6550 is not valid anymore.
6552 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6553 the connection. After that it sets SILC_SET_DISCONNECTED.
6554 It is, however, possible that the socket data is not still freed.
6555 The silc_server_packet_process now checks that data is not
6556 read or written to connection that is DISCONNECTED. The socket
6557 get's freed when the reference counter hits zero.
6559 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Changed the client operation API: channel_message operation's
6562 `sender' is now the client entry of the sender, not the nickname
6563 and the `channel' is the channel entry, not the channel name.
6565 In the private_message operation the `sender' is now also the
6566 client entry of the sender not the nickname.
6568 Affected file is lib/silcclient/ops.h and all applications
6569 using the client operations.
6571 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Moved the calling of ops->connect() from connect_to_server_final
6574 into receive_new_id functin since that is the point when the
6575 client is actually allowed to send traffic to network. The
6576 affected file is lib/silcclient/client.c.
6578 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6581 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6582 (if needs broadcasting) instead of broadcasting the packets one
6583 by one which would make a burst in the network traffic.
6585 * Added `broadcast' argument to the functions in silcd/server.[ch]
6586 silc_server_create_new_channel[_with_id] to indicate whether
6587 to send New Channel packet to primary router.
6589 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Added new function into the silcd/server.[ch] files:
6592 silc_server_create_new_channel_with_id to create new channel with
6593 already existing Channel ID.
6595 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6596 lib/silccore/silcpacket.h. This packet is used t send list of
6597 Set Mode payloads inside one packet. Server uses this to set
6598 the modes for the channels and clients on those channels, that it
6599 announced to the router when it connected to it. The protocol
6600 specification has been updated accordingly.
6602 * The silc_server_new_channel did not handle the packet coming
6603 from normal server as it normally does not send that. However,
6604 when it announces its channels it does send it. Implemented
6605 the support for that.
6607 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6608 into the file lib/silccore/id.h.
6610 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Fixed memory leaks in the functions silc_idlist_del_client,
6613 silc_idlist_del_channel and silc_idlist_del_server in the file
6614 silcd/idlist.c. All of those leaked like a sieve.
6616 * Fixed some small memory leaks in the client's function
6617 silc_client_notify_by_server.
6619 * Added functions into silcd/server.c: silc_server_announce_clients,
6620 silc_server_announce_channels and silc_server_announce_server.
6621 These functions are used by normal and router server to announce
6622 to its primary router about clients, channels and servers (when
6623 router) that we own. This is done after we've connected to the
6626 These functions effectively implements the following packet types:
6627 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6628 and SILC_PACKET_NEW_ID_LIST.
6630 * Added new functions into the silcd/packet_receive.[ch]:
6631 silc_server_new_id_list, silc_server_new_channel_list and
6632 silc_server_new_channel_user_list to handle the incoming
6633 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6635 * Added support of changing Channel ID in the function
6636 silc_server_replace_id. If the server that announces a channel
6637 to the router already exists in the router (with same name but
6638 with different Channel ID), router is responsible to send
6639 Replace ID packet to the server and force the server to change
6640 the Channel ID to the one router has.
6642 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6643 client that the Channel ID has been changed by the router. The
6644 normal server sends this to the client. Client must start using
6645 the new Channel ID as the channel's ID.
6647 Implemented handling of this new type into lib/silcclient/client.c
6648 into the function silc_client_notify_by_server.
6650 * Added new function silc_idlist_replace_channel_id into the files
6651 silcd/idlist.[ch] to replace the Channel ID.
6653 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Call silc_server_command_identify_check always when processing
6656 the IDENTIFY command in silcd/command.c
6658 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6660 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6661 send keepalive packets. The packet can be sent by clients,
6662 servers and routers.
6664 Added function silc_socket_set_heartbeat into the file
6665 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6666 If not set, the heartbeat is not performed. The actual
6667 heartbeat is implemented in the low level socket connection
6668 library. However, application is responsible of actually
6671 Added silc_server_send_heartbeat to send the actual heartbeat
6672 packet into silcd/packet_send.[ch]. Server now performs
6673 keepalive with all connections.
6675 * Added silc_task_get_first function into lib/silcutil/silctask.c
6676 to return the timeout task with shortest timeout. There was a bug
6677 in task unregistration that caused problems. TODO has been
6678 updated to include that task system must be rewritten.
6680 * The client library will now resolve the client information when
6681 receiving JOIN notify from server for client that we know but
6682 have incomplete information.
6684 * Rewrote parts of silc_server_remove_from_channels and
6685 silc_server_remove_from_one_channel as they did not remove the
6686 channel in some circumstances even though they should've.
6688 * Encryption problem encountered in server:
6690 The LEAVE command used to send the Channel Key packet to the
6691 router immediately after generating it. However, the code
6692 had earlier sent Remove Channel user packet but not immediately,
6693 ie. it was put to queue. The order of packets in the router
6694 was that Channel Key packet was first and Remove Channel User
6695 packet was second, even though they were encrypted in the
6696 reverse order. For this reason, MAC check failed. Now, this
6697 is fixed by not sending the Channel Key packet immediately but
6698 putting it to queue. However, this is more fundamental problem:
6699 packets that are in queue should actually not be encrypted
6700 because packets that are sent immediately gets encrypted
6701 actually with wrong IV (and thus MAC check fails). So, packets
6702 that are in queue should be encrypted when they are sent to
6703 the wire and not when they put to the queue.
6705 However, the problem is that the current system has not been
6706 designed to work that way. Instead, the packet is encrypted
6707 as soon as possible and left to the queue. The queue is then
6708 just purged into wire. There won't be any fixes for this
6709 any time soon. So, the current semantic for packet sending
6712 o If you send packet to remote host and do not force the send
6713 (the packet will be in queue) then all subsequent packets to the
6714 same remote host must also be put to the queue. Only after the
6715 queue has been purged is it safe again to force the packet
6718 o If you send all packets immediately then it safe to send
6719 any of subsequent packets through the queue, however, after
6720 the first packet is put to queue then any subsequent packets
6721 must also be put to the queue.
6723 Follow these rules and everything works fine.
6725 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6727 * Added new function silc_server_remove_clients_by_server to
6728 remove all client entries from ID list when the server connection
6729 is lost. In this case it is also important to invalidate all
6730 client entires as they hold the invalid server entry. This
6731 fixes fatal bug when server has lost connection and will reconnect
6734 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Made some sanity checks to silc_server_daemonise like to check
6737 whether the requested user and group actually exists.
6739 * Added sanity check to SKE's silc_ske_responder_finish to check
6740 that the public and private key actually is valid.
6742 * Invalidate the client's nickname when receiving Replace ID
6743 packet and the Client ID is being replaced. This means that the
6744 server will query the nickname if someone needs it (client)
6747 * Sort the ID Cache in client library when the ID Cache data
6748 has changed (needs sorting).
6750 * Do not allow for SILC client to create several connections to
6751 several servers. The client does not support windows right now
6752 and generating multiple connections causes weird behaviour.
6754 Irssi-silc client does support windows and can handle several
6755 connections without problems, see: www.irssi.org and SILC plugin.
6757 * Fixed some places where client was added to the IDList. The
6758 rule of thumb is following (in order to get everything right):
6759 If the client is directly connected local client then the
6760 `connection' argument must be set and `router' argument must be
6761 NULL to silc_idlist_add_client function. If the client is not
6762 directly connected client then the `router' argument must
6763 bet set and the `connection' argument must be NULL to the
6764 silc_idlist_add_client function.
6766 * The funtion silc_server_packet_send_local_channel actually did
6767 not check whether the client was locally connected or not. It
6768 does that now. Fixed a bug related to LEAVE command.
6770 * Fixed Remove Channel User payload parsing bug in server's
6771 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6773 * The server's silc_server_save_channel_key now checks also the
6774 global ID list for the channel as it might not be in the local
6775 list. Fixed a bug related to LEAVE command.
6777 * Is this the end of the [<unknown>] buglet that has been lurking
6778 around for a long time? A little for loop fix in server's
6779 silc_server_command_whois_parse that is used by both IDENTIFY
6780 and WHOIS command. At least, this was a clear bug and a cause
6781 of one type of [<unknown>] buglet.
6783 * WHOIS and IDENTIFY commands call the function
6784 silc_server_command_[whois/identify]_check function even if
6785 we are not router server.
6787 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Added --with-gmp configuration option. If set the GMP
6790 is always compiled in the SILC source tree. If not set then
6791 it is checked whether the system has the GMP3 installed. If
6792 it has then the GMP won't be compiled (the system's headers
6793 and library is used), if it doesn't have it then the GMP is
6794 compiled in the SILC source tree.
6796 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Changed RSA private exponent generation to what PKCS #1
6799 suggests. We try to find the smallest possible d by doing
6800 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6801 not security fix but optimization.
6803 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Added new config entry [Identity] to fork the server and run
6806 it as specific user and group. A patch from Bostik.
6808 * Imported Dotconf configuration library into lib/dotconf.
6809 This will be used to create the SILC configuration files later.
6810 It will appear in the distsribution after this commit.
6812 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * A big code auditing weekend happening. Auditing code for
6815 obvious mistakes, bugs and errors. Also, removing any code
6818 Removed files for being obsolete:
6820 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6821 inline in the file lib/silcutil/silcbuffer.h)
6823 o lib/silcutil/silcbufutil.c (the header has inline versions)
6825 Changed code to fix possible error conditions:
6827 o The buffer formatting routines now check that the destination
6828 buffer really has enough space to add the data. This applies for
6829 both buffer formatting and unformatting
6830 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6831 unformatting was changed to accomodate following rules:
6832 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6833 sent to the function while XXX_*STRING will not allocate or copy
6834 the data into the buffer. Instead it sets the pointer from the
6835 buffer into the pointer sent as argument (XXX_*STRING used to
6836 require that the pointer must be allocated already). This change
6837 makes this whole thing a bit more consistent and more optimized
6838 (note that the data returned in the unformatting with XXX_*STRING
6839 must not be freed now). The routines return now -1 on error.
6841 o Tried to find all code that use buffer_format and buffer_unformat
6842 and added return value checking to prevent formatting and
6843 especially unformatting errors and possible subsequent fatal
6846 o Changed ske->x and ske->KEY to mallocated pointers in
6847 lib/silcske/silcske.h. Fixed possible data and memory leak.
6849 o Added return value checking to all *_parse* functions. Fixed
6850 many memory leaks as well.
6852 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6853 so that buffer overflows would not happen. All code now also
6854 checks the return value as it can fail.
6856 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * Added reconnection support to server if the normal server looses
6859 its connection to the router (for example if router is rebooted).
6860 The server performs normal reconnection strategy implemented
6861 to the server. Affected file silcd/server.c.
6863 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added new packet type SILC_PACKET_SET_MODE that is used to
6866 distribute the information about changed modes (for clients,
6867 channels and clients channel modes) to all routers in the
6868 network. Updated the protocol specification accordingly.
6870 Added functions into silcd/packet_send.c and
6871 silcd/packet_receive.c: silc_server_send_set_mode,
6872 silc_server_set_mode.
6874 Added new files silcmode.[ch] into lib/silccore that implements
6875 the encoding and decoding of Set Mode Payload. Added new type
6876 SilcSetModePayload. Moved the definitions of different modes
6877 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6879 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Oops, a little mistake in server's connection authentication
6882 protocol. The protocol is not ended with FAILURE but with
6883 SUCCESS if the authentication is Ok. :) Affected file is
6886 * Implemented NICK_CHANGE notify handling in server in the file
6887 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6888 the local clients on the channel. After the changing nickname
6889 in router environment snhould work and the [<unknown>] nickname
6890 should appear no more.
6892 The silc_server_replace_id function that receives the Replace ID
6893 payload now sends the NICK_CHANGE notify type also in the file
6894 silcd/packet_receive.c
6896 * Changed WHOIS and IDENTIFY command to support the maximum amount
6897 of arguments defined in protocol specs (3328 arguments). This
6898 fixed a bug that caused problems when there were more than three
6901 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Added extra parameter, command identifier, to the
6904 silc_client_send_command so that explicit command identifier
6907 Changed that ID list routines uses specific command identifier
6908 when sending WHOIS/IDENTIFY requests to the server so that they
6909 can be identified when the reply comes back.
6911 Affected files lib/silcclient/command.[ch],
6912 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6914 * Added `sender' argument to silc_server_packet_send_to_channel
6915 to indicaet the sender who originally sent the packet to us
6916 that we are now re-sending. Ignored if NULL. Affected file
6917 silcd/packet_send.[ch].
6919 * Added some server statistics support in silcd/server_internal.h
6920 SilcServerStatistics structure and around the server code. Also
6921 send some nice statistics information when client is connecting
6924 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Fixed channel ID decoding in server's JOIN command reply in
6927 silcd/command_reply.c
6929 * Fixed braodcasting of replace ID payload to not to send it if
6930 we are standalone server in silcd/packet_receive.c.
6932 * Fixed all channel message sending routines to not to send
6933 packets to clients that has router set, since they are routed
6934 separately in the same function earlier. Affects file
6935 silcd/packet_send.c and all channel packet sending functions.
6937 * In USERS reply, res_argv[i] are not allocated, the table
6938 is allocated. Thus changed that free the table, not its
6941 * In server's whois_check and identify_check if the client is
6942 locally connected do not send any WHOIS commands - they are not
6945 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Fixed some minor bugs in client when sending WHOIS command. The
6948 arguments was in wrong order.
6950 * Removed statis function add_to_channel from server in
6951 silcd/command.c that was previously used with the joining but
6954 * Tested USERS command in router environment successfully with two
6955 routers, two servers and two clients.
6957 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Reorganized the USERS command and command reply in client library
6960 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6961 When the command is given by user we register a pending command
6962 callback that will reprocess the command after the reply has been
6963 received from the server. When reprocessing the packet we then
6964 display the information. Thus, the USERS information is displayed
6965 now in the command callback instead of in the command reply
6966 callback. The processing of the command is same as previously
6967 when server has sent the command reply in the JOINing process.
6969 * Added to USERS command in silcd/command_reply.c to join the client,
6970 we didn't use to know about, to the channel after we've created
6971 a client entry for it. Also, for clienet we did know already still
6972 check whether it is on the channel or not and add it if not.
6974 * Removed silc_server_command_join_notify as the function and its
6977 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Changed the client's pending command handling to the same as the
6980 server's pending command handling. It is also now possible to
6981 execute command reply functions from other command reply
6982 function as the function callbacks for commands and command
6983 replies are one and same. The pending commands are not static
6984 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6985 in client connection context. Thus, pending commands are server
6986 connection specific as it is convenient.
6988 Changed the function silc_client_command_pending and
6989 silc_client_command_pending_del and added new function
6990 silc_client_command_pending_check. Removed the
6991 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6994 * Added cmd_ident, current command identifier, to the client
6995 connection context in lib/silcclient/client.h to keep track on
6996 command identifiers used in command sending. Client's command reply
6997 function handling now supports the mandatory command identifiers.
6999 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7000 funtions in client to fully support pending command callbacks.
7002 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7003 as one of the arguments to the application in the command reply
7006 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7007 before first releasing SILC but came back. Now it is removed again
7008 and should come back nomore. The FORWARDED flag was used only
7009 by the JOINing procedure by forwarding the command packet to router.
7010 Now, the JOINing procedure has been changed to more generic (due
7011 to various router environment issues) and FORWARDED is not needed
7012 anymore for anything. The protocol specification is yet to be
7015 Now, removed silc_server_packet_forward from server and the flag
7016 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7018 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Renamed NAMES command to USERS command. The NAMES was named that
7021 due to historical reasons. Now it is renamed. Also, rewrote
7022 parts of the USERS command. The nickname list is not sent anymore
7023 by the server. Only Client ID and mode lists are sent in the USERS
7024 command. Changed this also to the protocol specification.
7026 The client now resolves the names and stuff after it receives
7027 the USERS list from the server when joining to the channel.
7029 * WHOIS and IDENTIFY commands has been changed to support multiple
7030 Client ID's per command. One can now search for multiple users
7031 in the network by sending only one WHOIS or IDENTIFY command.
7032 Changed the code and the protocol specifications.
7034 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7035 uses silc_server_command_whois_parse to parse the request. */
7037 * If normal server, do not parse the WHOIS and IDENTIFY requests
7038 before sending it to the router. Saves some time.
7040 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Fixed JOIN command on client library. Wrong number of arguments
7043 used to crash the client.
7045 * Added silc_server_channel_has_global function to check whether
7046 channel has global users or not.
7048 * Added silc_server_channel_has_local function to check whether channel
7049 has locally connected clients on the channel.
7051 * The silc_server_remove_from_one_channel now checks whether the
7052 channel has global users or not after given client was removed from
7053 the channel. It also checks whether the channel has local clients
7054 on the channel anymore. If it does not have then the channel entry
7055 is removed as it is not needed anymore.
7057 * The silc_server_notify now checks on JOIN notify whether the joining
7058 client is one of locally connected or global. If it is global then
7059 the channel has now global users on the channel and that is marked
7060 to the channel entry. Also, it now saves the global client to
7061 global list who is joining and JOINs it to the channel. This is
7062 for normal server, that is.
7064 Changed silc_server_send_notify_on_channel,
7065 silc_server_packet_relay_to_channel and
7066 silc_server_packet_send_to_channel check if we are normal server
7067 and client has router set (ie. global client) do not send the
7068 message to that client, as it is already routed to our router.
7070 * Implemented LEAVE notify type handling in silc_server_notify
7073 * Tested LEAVE command in router environment successfully. Tested
7074 with two routers, two servers and two clients.
7078 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7080 * Implemented SIGNOFF notify type handling in silc_server_notify
7083 * silc_server_remove_id now removes the client entry from all channels
7084 it has joined and thusly sends SIGNOFF notify type.
7086 * Rewrote the NAMES list generation in server by removing two excess
7087 loops. The lists are created now inside one loop.
7089 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * silc_server_remove_channel_user checks now also global list
7092 for channel and client.
7094 * silc_server_new_channel_user checks now both local and global
7095 list for channel and client. Fixed a bug in client id decoding.
7096 Used to decode wrong buffer.
7098 * silc_server_channel_message checks now both local and global
7099 list for channel entry.
7101 * Tested channel joining (hence JOIN) in router environment
7102 successfully. Tested with two routers, two servers and two
7105 * Tested channel message sending in router environment successfully.
7107 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Added silc_server_save_channel_key into server.[ch] to save the
7110 received channel key in Channel Key payload processing. It is
7111 also used in JOIN command reply handling.
7113 Equivalent function silc_client_save_channel_key added into
7114 client.[ch] into client library.
7116 * Changed JOIN command reply to send information whether the channel
7117 was created or not (is existing already) and the channel key
7118 payload. Changed protocol specs accordingly.
7120 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7121 the request was sent by ID and not by nickname. Crashed on
7124 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7126 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7127 now correctly save the received data.
7129 * silc_server_free_sock_user_data now notifies routers in the
7130 network about entities leaving the network.
7132 At the same time implemented functions silc_server_remove_id
7133 and silc_server_send_remove_id to receive and send REMOVE_ID
7134 packets. The packet is used to notify routers in the network
7135 about leaving entities. The ID removed will become invalid in
7138 * Added function silc_idlist_del_server into server. Removes and
7139 free's server entry from ID list.
7141 * silc_server_private_message function now checks, if we are router,
7142 that the destination ID really is valid ID, naturally.
7144 * In router when NEW_ID packet is received (for new client) the
7145 hash of the Client ID is saved in the ID Cache but the
7146 client->nickname is set to NULL, instead of putting the hash
7149 IDENTIFY command now also checks that client->nickname must be
7150 valid. If it is not if will request the data from the server who
7151 owns the client. Added new function
7152 silc_server_command_identify_check.
7154 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7155 to set the command to already allocated Command Payload.
7157 * Tested private message sending in router environment with two
7158 routers, two servers and two clients. Fixed minor bugs and now
7161 * Fixed segfault from client's NAMES command. Used to crash if
7164 * Forwarded packets must not be routed even if it is not destined
7165 to the receiver. Changed server code comply with this.
7167 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7169 * Added `require_reverse_mapping' boolean value to ServerParams
7170 structure. If TRUE (not default) the server will require that
7171 the connecting host has fully qualified domain name.
7173 If the reverse mapping is not required and hostname could not be
7174 found the IP address is used as hostname.
7176 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Implemented version string checking to both client and server.
7179 The check is incomplete currently due to the abnormal version
7180 strings used in development version of SILC.
7182 * Changed all command functions in server to use the new
7185 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Changed char *data to unsigned char *data in ID Cache system to
7188 support binary data as ID Cache data. Changed code to support
7189 binary data in lib/silccore/idcache.c.
7191 * Renamed silc_server_packet_relay_command_reply to
7192 silc_server_command_reply as it is normal packet receiving
7193 function. Rewrote the function to accept command replys for
7194 servers and not only for clients.
7196 * Mark remote router always as registered server if we are connecting
7197 to it. Otherwise, commands sent by the router to us are ignored.
7199 * All ID List find routines now returns the ID Cache Entry pointer
7200 as well if requested.
7202 * WHOIS command works now in router environment, tested with two
7203 routers, two servers and two clients.
7205 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7206 in router environment (as it is almost equivalent to WHOIS) but
7207 hasn't been tested thoroughly. Added new functions:
7209 silc_server_command_identify_parse
7210 silc_server_command_identify_send_reply
7211 silc_server_command_identify_from_client
7212 silc_server_command_identify_from_server
7214 * Disabled route cache adding because adding two different ID's with
7215 same IP replaces the old cache entry thus giving wrong route.
7216 The entry->router->connection is always the fastest route anyway
7217 so route cache may not be needed. Of course, new routes maybe
7218 established after receiving the ID when the entry->router->connection
7219 might not be anymore the most optimal.
7221 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Add route cache for received ID for fast routing.
7225 * Added silc_server_packet_route to route received packet on router
7226 that is not destined to us.
7228 * Renamed silc_server_get_route to silc_server_route_get.
7230 * Added id_string and id_string_len fields into SilcServer to
7231 include encoded ServerID for fast comparing without excess
7232 encoding of the ID's.
7234 * Cleaned up WHOIS command on server side. Added following static
7237 silc_server_command_whois_parse
7238 silc_server_command_whois_check
7239 silc_server_command_whois_send_reply
7240 silc_server_command_whois_from_client
7241 silc_server_command_whois_from_server
7243 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7244 arguments in command replies. All command functions should be
7245 updated to use this macro.
7247 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7249 * Minor typo fixes on command reply handling on server.
7251 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7253 * Added silc_server_command_add_to_channel internal routine to add
7254 the client to the channel after router has created the channel and
7255 sent command reply to the server.
7257 * Added generic silc_server_send_command to send any command from
7260 * Use static buffer with ID rendering instead of duplicating data.
7262 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7264 * Fixed a channel user mode bug when joining to a channel server gave
7265 everybody channel founder rights, oops.
7267 * We mark ourselves as the router of the incoming server connection
7268 if we are router ourselves. This way we can check in some packet
7269 sending functions whether it is locally connected server. For
7270 incoming router connections we put NULL.
7272 * For router sending packets locally means now always sending the
7273 packet cell wide; to local clients and local servers. For normal
7274 server sending packet locally means sending it to only local
7277 * Fixed the JOIN command to really work in router environment. If the
7278 channel is created it is always created by the router. Router is
7279 also responsible of making the initial joining to the channel,
7280 sending JOIN notify to the sending server and distributing
7281 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7282 does not exist server doesn't do anything else but forward the
7283 command to the router which performs everything.
7285 * Added silc_server_send_channel_key function to send the Channel Key
7288 * Added silc_server_create_channel_key to create new channel key. The
7289 channel key is now re-generated everytime someone joins or leaves
7290 a channel, as protocol dictates. Note: channel->key_len is the
7293 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7296 packet_receive.[ch] to separate packet sending and receiving
7297 routines. The server.[ch] now includes everything else including
7298 actual packet processing (writing and reading data) and other
7301 Renamed silc_server_private_message_send_internal to
7302 silc_server_send_private_message. The routine is still though
7303 used only to relay private messages as server does not send
7304 private messages itself.
7306 Renamed silc_server_new_channel to silc_server_create_new_channel
7307 and added new function sicl_server_new_channel that handles the
7308 incoming New Channel packet. Added also new sending function
7309 silc_server_send_new_channel to send New Channel Payload.
7311 * Added new function silc_server_notify to process incoming notify
7312 packet to the server/router. Server may then relay the notify
7313 to clients if needed.
7315 * Added new function silc_server_new_channel_user to process incoming
7316 New Channel User packet. Router will redistribute the packet and
7317 send JOIN notify to its local clients and locally connected servers
7318 if needed. Normal server will send JOIN notify to its local client
7319 on same channel when received this packet. Added also corresponding
7320 sending function silc_server_send_new_channel_user to sent the
7323 * Added boolean route argument to send_notif_to_channel and
7324 packet_send_to_channel functions to attempt to route the packet
7325 if it is TRUE and send only locally if it is FALSE.
7327 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7329 * silc_server_replace_id now broadcasts the received replace ID
7330 packet if it is not broadcast packet already. The router must
7331 broadcast to inform other routers about changed ID.
7333 * Added backpointer to server's router into SilcServer context in
7334 silcd/server_internal.h.
7336 * Fixed silc_server_packet_broadcast to send correct broadcast
7339 * The channel key is now distributed to the local client as soon
7340 as it is received from the router (in router environment) so that
7341 no other packet may be sent for the channel until client has
7344 * silc_server_remove_channel_user now broadcasts the received
7345 Remove Channel User packet if it is not broadcast packet already.
7346 The router must broadcast to inform other routers about removed
7349 * Added users field into SilcPacketContext that is a reference count
7350 of the context. One can increase the reference count by calling
7351 silc_packet_context_dup which is now changed to just increase the
7352 reference count instead of duplicating the data. The reference
7353 count is decresed by calling silc_packet_context_free that will
7354 free the data after the reference count hits zero.
7356 For now on the packet context and everything allocated into it
7357 (including the raw packet from network) must be freed by calling
7358 the new silc_packet_context_free function. Added also new function
7359 silc_packet_context_alloc that must be used now to allocate the
7360 context. This also means that if a routine is asynchronous from
7361 silc_[client/server]_packet_parse_type the packet context must
7362 be duplicated by calling silc_packet_context_dup. Otherwise it
7363 gets free'd after silc_[client/server]_packet_parse_type returns.
7364 Also, one must remember that if packet is duplicated then its
7365 reference count must be decresed by calling the free function as
7366 many times as it was duplicated.
7368 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7369 from both client and server.
7371 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7373 * Made joining to a channel working in router environment.
7375 * Cleaned up JOIN command on server side and create function
7376 silc_server_command_join_channel internal routine to make the
7379 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7381 * Changed silc_command_pending list to SilcDList. Also, added
7382 `ident' field to SilcServerCommandPending structure to identify
7383 the reply and to call correct callback.
7385 Added silc_server_command_pending_check function to replace the
7386 corresnponding macro. The silc_command_pending list is not
7389 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7390 to set identifier to previously allocated Command Payload. It
7391 is used to set identifier for command when resending Command
7394 * Added silc_command_payload_encode_payload to encode Command
7395 Payload buffer from SilcCommandPayload structure.
7397 * Added silc_argument_payload_encode_payload to encode Argument
7398 payload buffer from SilcArgumentPayload structure.
7400 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Changed WHOIS command to support router connection on server side.
7403 The whois request is always sent to router unless the server is
7404 standalone server. After server has received the reply from the
7405 router will it send the reply to the client.
7407 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7408 broadcast received broadcast packet. The function is used only
7409 by router. The broadcast packet is always sent to the router's
7412 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7413 render given ID to printable string, for log files for example.
7415 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7417 * Made basic router to router connections working. At least they
7418 can now connect to each other but nothing really works the way
7419 they are supposed - yet.
7421 * Added new initiator token to RouterConnection configuration
7422 file in silcd/serverconfig.[ch]. It is used to tell whether we
7423 are the initiator to the remote router or whether we'll expect
7424 the other end to connect.
7426 * Moved registering of listener task to silc_server_init, hence
7427 the server starts listenning as soon as it is run, even if it
7428 does not have connections to other routers. Let's see how well
7431 * Changed default connection retry timeouts for more suitable in
7434 * Removed cipher and such arguments from silc_idlist_add_client
7435 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7436 Added new function silc_idlist_add_data to add the keys and stuff
7439 * Added SilcIDListData structure and added it to SilcClientEntry
7440 and SilcServerEntry as their first field in the structure. This
7441 way we can explicitly cast the ID entries to the SilcIDListData
7442 structure and get common data for the entries. In past, we had
7443 to first check what type of connection it is and then cast it to
7444 correct ID entry type. Now, we can directly cast the opaque
7445 pointer to the SilcIDListData (no matter what ID entry it actually
7446 is) and get the data needed.
7448 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7450 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7451 in some circumstances even if threre were timeout tasks, though not
7452 IO tasks, but tasks anyway. Now fixed.
7454 * Defined SilcServerConnection structure to hold connection specific
7455 stuff about directly connected servers and routers. The definition
7456 is currently in silcd/server_internal.h. I thought about having
7457 a bit more important role fro this struct but for now it is used
7458 only when connecting to other server (or router actually).
7460 * Added connecting retry support in server when connecting to
7461 router(s). The retry feature implement exponential backoff
7462 algorithm. Also, added SilcServerParams structure to hold default
7463 parameters for server. For now, it include these retry settings
7464 and are hard coded. After server is moded to be as Silc Server
7465 Library this structure will be more important.
7467 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7469 * Changed client librarys channel->clients table to SilcList and
7470 changed code accordingly.
7472 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7474 * Changed client's channel table to SilcList and changed code
7475 accordingly. Also changed SilcChannelClientEntry to include back-
7476 pointer to the channel so that client entry can use that structure
7477 as list as well and we have fast cross-reference to the channel.
7478 This change dramatically decreased the complexity of channel
7479 handling with client entry and vice versa (removed one extra
7480 loop when searching for channel entry from many functions).
7482 * Changed server->sim from table to SilcDList and changed code
7485 * NAMES command can now be used from user interface. It will show
7486 the user list on the channel, neatly.
7488 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7489 Code now saves realname of the user if it becomes available.
7491 * Renamed configure.in to configure.in.pre and made ./prepare
7492 script to automatically add correct version string to
7493 configure.in which it creates from configure.in.pre.
7495 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * NAMES command reply now shows users mode with the nickname when
7500 * Moved silc_client_ch[u]mode[_char] functions from
7501 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7502 place sucks, they are utility functions and should be in some
7505 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7507 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7510 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7514 * Added TRQ (efficient deque and list library) into lib/trq. This is
7515 a very good list library that is currently used in the SILC. Defined
7516 SilcList API over the library because I didn't like the API very
7517 much. See lib/trq/silclist.h for the API and examples of how to
7518 use the API. Fixed various places in the code to use the new
7519 SilcList API. The SilcList is meant for lists that has a structure
7520 already defined as a list. It is not suitable to add just some
7521 context to the list (in TRQ, the context is the list actually).
7523 So, I defined SilcDList that can be used for the purpose where
7524 predefined list structure does not exit. This can be used as
7525 such list. Now some context just can be added to the SilcDList.
7526 Currently this list is not used in the SILC just yet, though there
7527 are a lot places where this can replace dynamically allocated
7528 tables and I will fix these places, later, to use SilcDList.
7529 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7530 and use TRQ internally).
7532 Also fixed some annoying warning messages that the original TRQ
7533 code generated. Also minor changes to TRQ's Makefile.in.
7535 * Added support for querying by Client ID to both WHOIS and
7536 IDENTIFY commands into server, as required by the protocol.
7538 * Removed method function pointers from SilcBuffer structure. They
7539 weren't used to anything and just increased the context size for
7540 no good reason. This change also made silc_buffer_alloc and
7541 silc_buffer_free functions inline functions.
7543 * Disabled command flooding detection support until it's fixed so
7544 that it accepts commands in but does not execute them more than once
7547 * Added silc_net_localhost(), to return local hostname, into
7548 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7549 that must be initialized before calling silc_client_init.
7551 * Added new function: silc_server_send_notify_on_channels to send
7552 notify messages to all channels client has joined. It is assured
7553 that the message is sent only once per client.
7555 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7556 lib/silcutil/silcutil.[ch] as silc_format function. The new
7557 function is generic and is used by server as well, not only by
7558 the logging routines.
7560 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7561 the provided version string was not acceptable. Added new function:
7562 silc_ske_check_version into lib/silcske/silcske.h. The function
7563 must be implemented by the application (client or server) and it
7564 does not reside in the SKE library. The function checks the version
7565 string remote end sent.
7567 * Added back pointers (to opaque context and to SilcSocketConnection)
7568 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7570 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7571 duplicate packet context structure.
7573 * Changed `notify' client operation to send same arguments as client
7574 receives from server except for ID's. ID's are mapped to correct
7575 ID entry and that is returned. Also, if channel entry is not sent
7576 by server but the notify is for channel the channel entry is sent
7577 to application (otherwise application doesn't know that it is for
7578 channel (library gets it from packet's Destination ID)).
7580 * Added silc_client_remove_from_channels into client library to
7581 remove a client from all channels it has joined to. Used when
7582 received SIGNOFF notify from server. Added also new function
7583 silc_client_replace_from_channels to replace old ID entry with
7584 new ID entry on all channels. Used when received NICK_CHANGE
7587 * Fixed ID Cache list handling in silc_idlist_get_client in
7588 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7589 to get (or query) client by ID.
7591 * Updated TODO list.
7593 * Added connection authentication status message defined by the
7594 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7595 support for these into the code in client and server side.
7597 * Added generic function silc_client_send_command to send any command
7598 with variable argument list. Application should use this function
7599 to send commands if the command functions provided by the library
7600 does not suite for the application's user interface needs.
7602 * Added new `failure' client operation. Application is notified about
7603 received failure packet if client is executing a protocol. In this
7604 case the protocol's execution has failed.
7606 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7607 is required by the protocol.
7609 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7610 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7613 * Added status flag to SilcSKE object to indicate realtime status
7614 of the SKE protocol.
7616 * Application receives now exactly same command reply arguments as
7617 the library receives from server. However, if ID is received the
7618 corresponding ID entry is returned to the application (eg. Client
7619 ID is mapped to correct SilcClientEntry entry and that is returned).
7620 Changed command_reply client operation due to this change.
7622 * Changed all ID's in commands and in command replys as ID Payloads.
7623 Change affected both client and server side codes.
7625 All ID's sent in SILC network (with execption of ID's in SILC
7626 Packet header) are sent in ID Payload to support variable length
7629 * Server now notifies nick changes and notifies all clients on
7630 the channels about the new nickname (about the new Client ID,
7633 * Implemented CMODE command to change channel modes. Supports all
7634 channel modes defined by the protocol specs except ban and invite
7635 lists. (Also, private channel key mode is supported but support for
7636 setting private channel key in client is missing, thus, this mode
7637 has no effect on client side (except that server requires that the
7638 client uses private channel key and normal channel traffic does not
7641 Also, invite mode works per se, but INVITE command does not work
7642 yet correctly, so you can set channel as invite only channel but
7643 inviting clients to the channel does not work (it is yet to be
7644 thought what's the best way to do it).
7646 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7647 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7648 Implemented CUMODE command to change user's mode on the channel.
7649 Supports all modes defined by the protocol specs.
7651 * Added NAMES command reply to return users modes on the channel.
7653 * Removed unnecessary and slow ciphers from lib/silccrypt.
7655 * Set SO_KEEPALIVE option to connection sockets by default.
7657 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7659 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7660 redefined the Notify Payload into protocol specs.
7662 * Added silc_id_payload_parse_id to get ID directly from raw
7665 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7668 accept searching by Client ID as well.
7670 * Added support for LEAVE and SIGNOFF notify types in client library.
7672 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7673 to parse ID Payload from raw data.
7675 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Added flags parameter into silc_ske_assemble_security_properties
7678 function in lib/silcske/silcske.[ch].
7680 * Changed notify client operation to fit better for notify messages
7681 sent by server. The notify payload received from server is now
7682 passed to the application (after parsing it to SilcNotifyPayload).
7683 It is application's responsibility to retrieve the arguments
7684 from the payload and show the message the way it wants. The message
7685 sent by server is implementation specific.
7687 * Changed public keys to comply with the protocol specification.
7688 Old public keys are not supported anymore and are not compatible.
7690 * Removed nickname from Channel Payload as the latest draft removed
7691 it. The client must resolve the nickname from the NAMES command
7692 reply received when it joined the channel.
7694 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7696 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7698 * Fixed some errors in protocol specification drafts.
7700 * Created lib/silccore/silcnotify.c to implement Notify Payload
7701 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7702 generic payloads described by protocol specifications. The file
7703 includes implementations for ID Payload and Argument Payload.
7705 * Changed Command Payload implementation to use the new Argument
7706 Payload. Changed command_xxxx_payload to command_payload_xxxx
7707 to comply with SILC coding conventions.
7709 * Added suppport for Argument Payload handling in Notify Payload
7710 implementation as protocol requires it. Added the new support
7711 into server and client lib as well.
7713 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7715 * Added support for multiple nicknames on same channel. [n] is
7716 added locally to the nickname if there are more than one same
7717 nicknames on the channel.
7719 * Server now sends all nicknames that matched WHOIS request.
7720 Client also shows the list received from server.
7722 * Added TOPIC command to client side. User can now set and show
7723 current topic on channel.
7725 * Added MOTD command to client and server. Also, server sends the
7726 motd when client connects to the server.
7728 * Changed version strings to comply ISO 8601.
7730 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7732 * Fixed protocol error handling in client library. It should now
7733 cope even if the SKE fails for some reason.
7735 * Made new protocol specification drafts for submitting to IETF.
7737 * Implemented TOPIC command to server in silcd/command.c.
7739 * Added two new notify types into lib/silccore/silcnotify.h:
7740 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7741 notify nickname change and topic setting/change on a channel.
7743 * API change of command_reply operation in client library. The
7744 application gets now the status type received from server as well.
7746 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7748 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7750 * Cras fixed and optimized the packet handling even further and
7751 it should work now. Minor change to the prototype of function
7752 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7754 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Added new function into lib/silcutil/silcschedule.[ch]:
7757 silc_schedule_with_fd to select() a specified fd. The function
7758 returns after timeout expires or data arrives or goes. The
7759 function is used by packet routines to wait that all data is
7760 received from network.
7762 * Fixed data reading from network in lib/silccore/silcpacket.c.
7763 The code now assures that all data is read from the fd and then
7764 continues packet processing. This was a bug fix since the code
7765 used to drop some data in some circumstances.
7767 * Added new function into lib/silcclient/client.[ch]:
7768 silc_client_start_key_exchange to start key exchange after
7769 connection has been established to server. The code internally
7770 now uses this funtion but its main purpose was to provide it
7771 for applications that perform their own connecting. After
7772 application has created a connection it merely calls this
7773 function to start the key exchange between client and server.
7774 The library takes care of everything else after that.
7776 Updated also lib/silcclient/README to explain the usage of
7779 * Do not send to application information that connection has
7780 been established. Application gets notified it by connect
7783 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * Applied cras's patch to add silc_schedule_one function. The
7786 function runs scheduler once and returns.
7788 * Fixed the scheduler after cras messed it up. The timeout
7789 handling works now as it's supposed to work.
7791 * Added into lib/silccore/ silcnotify.h to include notify
7792 message types support. Changed silc_server_send_notify*
7793 functions, in server.[ch], to support those new notify types.
7794 Added the support for the notify types into client library,
7795 as well. Added new notify client operation into ops.h in
7798 * Changed silc_server_packet_send_to_channel to send normal
7799 packets instead of just channel message packets. The function
7800 is now used to send the notify packets to channels. It is not
7801 used to send channel message packets anymore, as server never
7804 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7805 va_arg()s as it seems to require it nowadays. I guess, if SILC
7806 is compiled with older va_arg() the new code should work anyway.
7808 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7810 * Splitted core library. Core library (lib/silccore) includes
7811 now only SILC protocol specific core (and common) components.
7812 Created new utility library (lib/silcutil) that includes more
7813 generic purpose stuff. The stuff for util library was taken
7814 from the old core library. This was minor and easy split.
7816 * Created SILC Client Library (lib/silcclient) that includes
7817 implementation of the SILC client without user interface. This
7818 was major move from silc/ directory. The code has been changed
7819 so that it is transparent towards the user interface. The
7820 silc/ directory includes now the same user interface as before
7821 and it uses the new client library. Read lib/silcclient/README.
7822 Basicly, the client library performs everything else related
7823 to SILC except user interface handling. Also, configuration
7824 files are considered to be part of user interface and library
7825 does not handle them.
7827 This change also changed a lot of structures, function naming etc.
7828 Most important change was that SilcClientWindow object was
7829 renamed to SilcClientConnection in the client library. Created
7830 also new file lib/silcclient/ops.h. Also added new files
7831 silc/local_command.[ch] and silc/client_ops.[ch].
7833 All these changes were made to make it easier for user interface
7834 designers to create what ever user interface for the SILC client
7837 It is also expected that the server will be moved to lib
7838 directory as well and SILC Server Library will be created;
7839 sometimes in the future.
7841 * Removed Local commands from lib/silccore/silccommand.h as
7842 they are application specific and new client library does not
7843 handle any of those anymore.
7845 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7846 old client implementation in silc/.
7848 * Added support for callback functions in SILC_LOG_* macros.
7849 Application can now set its own callbacks that will be called
7850 instead of using the default functions that will always print
7851 the debug messages to stderr (or stdout). Also, debugging can
7852 now be disabled by setting silc_debug to FALSE and re-enabled by
7853 setting it to TRUE. Note, that logging will still work even
7854 if debugging is disabled.
7856 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7857 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7858 silc_log_reset_debug_callbacks.
7860 * To enable debugging in silc client one must give now -d
7861 option on command line.
7863 * Changed silc_schedule_init to automatically allocate task queues
7864 if they are not allocated before calling it.
7866 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Added GMP 3.1 into math library.
7870 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7872 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7873 a channel in SILC network. The packet is used by servers and
7874 routers to notify other routers that user has left a channel.
7875 This little feature was missing until now. Added the feature
7876 to protocol specification as well.
7878 Added functions: silc_server_send_remove_channel_user and
7879 silc_server_remove_channel_user into server.[ch].
7881 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7882 lib/silccore/silcpacket.h. However, they are not implemented
7885 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7887 * Fixed joining to a channel and sending channel messages
7888 between server and router. The channel message sending should
7889 now work inside a cell.
7891 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7893 * Fixed the private message sending between server and router.
7894 The private message sending should now work inside a cell.
7896 * Added silc_server_replace_id into server.[ch] to replace
7897 existing ID in the SILC network.
7899 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7900 and silc_idlist_replace_server_id into idlist.[ch] in server.
7902 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7904 * Fixed the server to server connections. Server can again now
7905 connect to router. Router to router connections probably does
7908 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7910 * Added dynamic protocol registering support. Now protocols can
7911 registered and unregistered on the fly. Patch by cras.
7913 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7915 * Added lib/contrib directory to hold routines that some platforms
7916 don't have but are needed by SILC.
7918 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7919 into lin/contrib to provide getopt() and getopt_long() for
7920 those who don't have it.
7922 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7924 * Added AWAY command to client. When away message is set and
7925 client receives a private message packet the client automatically
7926 replies to the sender with the away message.
7928 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7929 bug seemed to be the cause of recent problems when compiling
7932 * Added version detection support to SKE protocol specification
7933 and added the new changes to the SKE implementation as well.
7934 There were other minor changes in the SKE protocol as well.
7936 Many changes in lib/silcske/silcske.[ch] and in
7937 lib/silcske/payload.[ch].
7939 * Added ^U functionality, clear input line. Patch from cras.
7941 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7943 * Mainly small bugfixes on core library. Fixed some debugging
7944 logging and buffer overflow in silclog.c.
7946 * Updated config.sub and config.guess on the distribution tree.
7948 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7950 * Added command lagging support in server. Client may execute
7951 commands now only once in two seconds.
7953 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7955 * Optimized packet reception. MAC computation and checking is now
7956 also more optimized. A lot previously duplicated code is now
7957 used as generic by both client and server.
7959 * Fixed key pair generation in clientutil.c
7961 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * Added into lib/silccore/silcbufutil.[ch] new function;
7964 silc_buffer_realloc.
7966 * Moved generic packet sending/encryption functions to
7967 lib/silccore/silcpacket.[ch] from client and server. Some
7968 rewriting of the functions.
7970 * Moved all generic packet reception/decryption functions to
7971 lib/silccore/silcpacket.[ch] from client and server. The
7972 packet processing is now much cleaner in both client and server.
7973 These were major changes in both client and server.
7975 * Created many common functions in server to do packet sending.
7976 Previously code were duplicated a lot, this has been removed
7979 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7981 * Rewrote major parts of the ID cache system. Don't know
7982 whether it is better now or not but at least the API is more
7985 * Major rewrite on ID cache stuff on client because of the ID
7986 cache API changes. Added idlist.c to client.
7988 * Also major rewrite on ID cache stuff on server as well.
7989 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7990 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7991 in hand, instead they are all put into the ID cache system now.
7992 All server_idlist_* routines uses ID cache now instead of
7993 traversing its own lists (those lists does not exist anymore).
7994 SilcIDList though still exists. Also, SilcXXXEntry's are
7997 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7999 * Finally made the SKE implementation compliant to the protocol
8000 specification. All mp integers are now binary encoded as
8001 opposed being HEX encoded.
8003 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8006 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8007 functions: silc_[encode/decode]_pem. Also added function
8008 silc_encode_pem_file to PEM encode with newlines ('\n') for
8011 * SILC public keys are now encoded either PEM or binary. Same
8012 option is for private keys as well. By default private keys
8013 are binary encoded and public keys PEM encoded. Silly HEX
8014 encoding were removed.
8016 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8017 function to create fingerprints.
8019 * Fixed a bug in SHA1; does not change the original data anymore.
8021 * Partly implemented INFO command on client and server side.
8022 Fixed CLEAR command. Changes to SERVER command; show current
8023 server(s) when giving command without arguments. Added
8024 VERSION command to client.
8026 * Added check to server that unregistered connections cannot
8027 execute commands (unless it is specificly allowed).
8029 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8031 * Fixed screen refresh.
8033 * Fixed channel joining bug from client. On some circumstances
8034 client tried to join to a channel it had already joined.
8036 * Added public key verification process into client's protocol.c.
8037 The client now verifies the public key from user and saves
8038 it into ~./silc/serverkeys/ directory.
8040 Added into: clientutil.[ch]: silc_client_verify_server_key.
8042 * Changed SKE protocol's silc_ske_initiator_finish function
8043 to accept callback function that verifies the received public
8044 key. Removed old silc_ske_verify_public_key function.
8046 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8048 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8049 silc_pkcs_private_key[_data]_set.
8051 * Made the password and public authentication more cleaner in
8052 server's protocol.c.
8054 * Removed historic and obsolete protocol `channel_auth' from
8055 both client and server.
8057 * Removed wrong way of sending command status messages from
8058 server to client in server's command.c. The old way violated
8059 protocol specification.
8061 Changes to silccore/silccommand.[ch]: removed
8062 silc_command_encode_status_payload -> not needed anymore,
8063 changed silc_command_encode_payload_va to accept extra
8064 argument on variable argument list. The argument type must
8065 now be provided to the function. Also, added new function:
8066 silc_command_encode_reply_payload_va which is same as
8067 normal command_encode_payload_va except command status type
8068 is provided as extra argument.
8070 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8072 * Added ~./silc directory handling. The directory includes the
8073 public and private keys for the client.
8075 Added silc_client_check_silc_dir, silc_client_create_identifier
8076 and silc_client_load_keys.
8078 * Implemented SILC protocol compliant public key. Added public
8079 and private key saving to and loading from files.
8081 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8082 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8083 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8084 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8085 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8087 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8088 silc_pkcs_load_[public/private]_key.
8090 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8092 * Added silc_server_get_route (route.[ch]) to get connection
8093 data for the fastest route for given ID.
8095 * Implemented INVITE command on client and server. The command
8096 were re-defined in the SILC Protocol Specification and the
8097 implementation now complies with the specification.
8099 * Implemented PING command on client and server.
8101 * Implemented NAMES command on client and server. The server side
8102 supports currently only normal server not router server yet.
8103 Some changes to NAMES definition in SILC protocol specification.
8105 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8107 * Implemented LEAVE command on client and server.
8109 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8110 again. This change was made to the protocol as well. Server
8111 should not violate the protocol specification anymore.
8113 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8116 was tested. SOCKS4 was not but should work anyway.
