22 * Added resolve_cmd_ident field to the SilcClientEntry structure
23 too so that if the entry is for example being resolved so
24 another command may attach to the same pending command reply
25 without requiring to resolve the same entry again. Added
26 support for adding multiple pending commands for one
27 command idenfier. Affected files lib/silcclient/command.[ch],
28 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
30 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
32 * Defined that server receives WHOIS command reply for private
33 and secret channels too. Updated protocol specs and the
34 code in server. Affected file silcd/command.c.
36 * Defined <channel user mode list> argument to WHOIS command
37 reply for returning user modes on the channels. The
38 channel list now doesn't include the user mode anymore but the
39 actual channel mode. Updated protocol specs and the code in
40 client and server. Affected files are silcd/command_reply.c,
41 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
42 and lib/silcclient/command_reply.c.
44 * Save the channels list in WHOIS command reply in normal server
45 so that WHOIS always shows joined channels also in normal
46 server and not just on router. Affected file is

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

140 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
142 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
144 * Added STATS command to the protocol after all, to return
145 various statistical information about the network. It can
146 be used by clients to retrieve statistical information, and
147 servers may use it to to fetch cell and network wide
148 statistics from router. Updated the protocol specs and
149 implemented it to the server. Protocol TODO #16.
150 Affected files are lib/silccore/silccommand, silcd/command.[ch],
151 silcd/command_reply.[ch].
153 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
155 * The LIST command reply in client libary now adds new channel
156 entry if the returned channel doesn't exist yet in cache,
157 and returns the channel entry to the application in the
158 command_reply client operation. Affected file is
159 lib/silcclient/command_reply.c.
161 * Changed the channel message payload's MAC generation to
162 include the IV in the MAC as well. This way all relevant
163 parts of the channel message payload are authenticated also
164 with the channel message MAC (and not only by packet MAC).
165 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
166 Affected file is lib/silccore/silcchannel.c.
168 * Fixed the SKE to save the remote version, since the
169 silc_ske_parse_version mistakenly checked wrong version,
170 after it replaced the start payload. Affected files are
171 lib/silcske/silcske.[ch].
173 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

177 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
178 Affected files lib/silcutil/silcstrutil.[ch].
180 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
181 files are lib/silcutil/silcstrutil.[ch].
183 * Defined that the security property fields in SKE SHOULD be
184 UTF-8 encoded, defined that version string MUST be US-ASCII
185 encoded, defined that passphrases sent in connection
186 authentication protocol MUST be UTF-8 encoded. Implemented
187 these to the client and server. Defined also that other
188 passphrases sent in the protocol MUST be UTF-8 encoded.
189 Affected files are lib/silcske/silcske.c,
190 lib/silcclient/protocol.c, silcd/protocol.c,
191 silcd/serverconfig.c, and lib/silccore/silcauth.c.
193 * Changed the silc_client_close_connection interface to not
194 need the SilcSocketConnection which should not be visible
195 to application. Affected files are lib/silcclient/client.c
196 and lib/silcclient/silcclient.h.
198 * Rewrote the text for Private Message Key Payload in the
199 protocol specification. Protocol TODO #11.
201 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Upgraded the protocol version to 1.1, updated protocol specs

214 Protocol TODO #13. Affected files are silcd/command.c,
215 silcd/packet_receive.c, packet_send.[ch],
216 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
217 The killer's client entry is now returned to application in
218 the `notify' client operation.
220 * Fixed the Max Argument fields that had too large value set
221 in the protocol specs. Protocol TODO #14.
223 * Added the LEAVE command reply to return the ID of parted
224 channel. Updated protocol specs and implemented it to the
225 client and server. Protocol TODO #15. Affected files are
226 silcd/command.c, lib/silcclient/command_reply.c. The channel
227 entry is now returned to application in the `command_reply'
230 * Rewrote the version SKE version checking in client libary
231 and in server to use the silc_parse_version_string. Affected
232 files are lib/silcclient/protocol.c, silcd/protocol.c.
234 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
235 commands that was missing it, and updated protocol specs and
236 the server implementation. Protocol TODO #10. The affected
237 file is silcd/command.c.
239 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
240 generic reply to a generic request (REQUEST flag), and
241 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
242 way. A draft-riikonen-silc-flags-payloads-00.txt is written
243 to define the payload for DATA flag. Added the flags to
244 the implementation. Protocol TODO #9. Affected file is
245 lib/silccore/silcchannel.h.
247 Changed the client library to return the message length
248 to application as well in the channel_message and private_message
249 client operations. Affected files are
250 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
251 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
252 and lib/silcclient/client_ops_example.c.
254 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
255 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
256 the channel. Updated protocol specs and impelemented this
257 to client and server. Protocol TODO #6. Affected files are
258 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

261 Added new options m and M to CMODE command in Irssi SILC
262 client to set these modes.
264 * Deprecated all administrative commands from SILC protocol
265 since they are highly implementation specific commands.
266 Updated protocol specs. Moved the old commands in
267 implementations to private range of command types. Affected
268 files are silcd/command.c, lib/silcclient/command.c and
269 lib/silcclient/command_reply.c. Protocol TODO #8.
271 * Fixed a bug in server where sending unknown command crashes
272 the server. Affected file silcd/command.c.
274 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
276 * Added SILC_PROTOCOLVERSION macro to check protocol version
277 of a socket connection. The affected file is
278 lib/silcutil/silcsockconn.h.

287 Affected file silcd/protocol.c.
289 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
291 * Some client implementations quit network by doing first LEAVE
292 and then immediately SIGNOFF (like Bombyx). We now do check
293 after a short time after LEAVE notify and check whether the
294 client is still valid after LEAVE, and if not we remove it from
295 cache. Affected file is lib/silcclient/client_notify.c.
297 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
299 * Merged version 1.1.4 of zlib. Even if it not currently in use,
300 it's good not to have security holes here.
302 * Fixed a negative refcount situtuation for the config context.
303 Affected file is silcd/serverconfig.c.
305 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
307 * ROBOdoc documented lib/silcutil/silcutil.h.
309 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
311 * Optimized even more the SilcPacketContext structure. Now
312 totally saved 16 bytes of memory per context after optimization.
313 Affected files are lib/silccore/silcpacket.[ch].
315 * Made strict checks for valid SILC IDs. Affected file is
316 lib/silccore/silcid.c.
318 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
320 * Changed the object argument for silc_cipher_register,
321 silc_hash_register, silc_hmac_register and silc_pkcs_register
322 to const. Affected files are lib/silccrypt/silccipher.[ch],
323 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
325 * Changed the silc_get_username and silc_get_real_name to
326 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
328 * Fixed the Irssi SILC Client to use the silc_get_username and
329 silc_get_real_name insted of glib routines since the glib
330 routines only corrupt stack. Fixes the Irssi SILC to work in
331 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
333 * Fixed the Irssi to not use g_get_home_dir since it crashes
334 or returns garbage on cygwin and corrupts stack. Added function
335 get_home_dir to Irssi routines. Affected files are
336 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
338 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
340 * Made some structure optimizations. SFTP memory FS MemFSEntry
341 entry structure. Optimized SilcTask structure. Optimized
342 SilcPacketContext structure.
344 Affected files lib/silcsftp/sftp_fs_memory.c,
345 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
347 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
349 * And yet again reverted back the config thing since Johnny
350 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
353 * Fixed memory leaks from config object. Affected files are
354 silcd/serverconfig.[ch].
356 * Added support for adding new connections to the server in rehash.
357 After rehash they take effect.
359 Added support for changing the maximum allowed connections in
360 rehash. The number can grow but going smaller is not supported.
362 Added function silc_server_num_sockets_by_remote to the
363 silcd/server_util.[ch].
365 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
367 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
369 * Added preliminary checking during config parsing for a valid
370 public/private key and removed further checks in the code.
371 Affected files are silcd/serverconfig.[ch], server.c.
373 * Moved functions silc_server_drop() and silc_server_daemonise()
374 from server.c to silcd.c since they are stricly related to
375 the application activity.
377 * Reverted a small part of the automatic ref/unref since
378 it caused a double unref in some situations. Affected
379 files are silcd/silcd.[ch], server.c, serverconfig.c.
381 * Added some .cvsignore files in the lib directory.
383 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
385 * Fixed silc_net_gethostbyaddr to correctly resolve by
386 address. Affected file lib/silcutil/silcnet.c.
388 * Fixed the notify relaying to client. The HMAC to be used
389 with relayed packets ws wrong and caused decryption failure
390 at the client end. Affected file is silcd/packet_receive.c.
392 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
394 * Created new branch silc_protocol_1_0_branch.
396 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
398 * Changed the silc_server_config_* routines to be SilcServer
399 independent. They are now officially application specific code
400 and not part of generic server implementation. Affected files
401 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
403 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
405 * Added automatic referencing of config context in the
406 silc_server_config_alloc, and automatic unreferencing in the
407 silc_server_config_destroy. Affected files are
408 silcd/serverconfig.[ch], silcd/silcd.c.
410 * Fixed the silc_log_quick handling in the logging routines.
411 It didn't log quickly when it was TRUE. Affected file is
412 lib/silcutil/silclog.c. Also the flush delay was set even
413 if it was 0 in config file. Affected file is
414 silcd/serverconfig.c.
416 * Added support for changing key pair of the server in rehash.
417 Affected file silcd/server.c.
419 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Fixed the TOPIC_SET notify to not cras. It changed the topic
422 too early, before getting the channel entry. Affected file
423 is silcd/packet_receive.c.
425 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
427 * Added functions silc_server_config_[ref/unref], these are used
428 to prevent that the config object is destroyed.
430 No longer directly affect global variables silc_log_quick and
431 silc_log_delay, they are first cached inside the config object
432 and then applied with silc_server_config_setlogfiles().
434 silc_server_config_set_defaults() is now internal to
435 serverconfig.c, there are no reasons to show this internal stuff
438 Affected files are silcd/serverconfig.[ch].
440 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
441 fprintf's to stderr, since some code may be executed again after
442 the server went into the background. Affected files are
445 * Added rehash support. Added function silc_server_rehash() that
446 will perform all the basic tasks of the rehashing procedure.
448 * Added command line option `-x, --hexdump'. This will enable the
449 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
450 The option `--hexdump' implies `--debug'.
452 * Fixed a bad bug in the logging APIs (silcutil library) where
453 the application would crash after calling silc_log_reset_all().
455 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
457 * Fixed the KICKED notify handling in client library to
458 correctly remove the channel and all entries from the
459 channel when I was kicked. This bug crashed the client.
461 Fixed yet another but in KICKED notify handling to remove
462 the kicked client correctly from the channel.
464 Affected file is lib/silcclient/client_notify.c.
466 * Fixed a minor bug in looking up correct client entry
467 in KICKED notify in server. Affected file is
468 silcd/packet_receive.c.
470 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
471 sources correctly to distribution. Fixes --with-gmp option.
473 * Removed the manual rehashing from ID Cache, and changed it
474 to use the SILC Hash Table's auto rehash feature. Affected
475 file is lib/silccore/silcidcache.c.
477 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
479 * Fixed a bug in the silc_client_nickname_format function that
480 handles the multiple same nickname formatting. Two clients
481 with same nickname caused problems after the first one left
482 and rejoined. It didn't format the nickname correctly.
483 Affected file is lib/silcclient/idlist.c.
485 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Don't change the topic if olod topic is same as new one.
488 Affected file is silcd/packet_receive.c.
490 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
492 * Added cross-reference support to the SILC Documentation
493 generator. All types across all HTML files are now cross-
494 referenced. Affected files util/robodoc/generator.c and
495 scripts/silcdoc/silcdoc.
497 * Added file lib/silcutil/silctypes.h to include all the
498 arithmetic type definitions and some macros. Removed
499 includes/bitmove.h and moved macros to silctypes.h.
501 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

507 * Added `type' argument to silc_id_payload_parse_id function which
508 now returns the type of the ID to the sent pointer. Affected
509 file is lib/silccore/silcid.[ch].
511 * Added check for CMODE_CHANGE notify type that mode change is
512 allowed by the sender. Affected file silcd/packet_receive.c.
514 * Added check for CUMODE_CHANGE notify type that mode change is
515 allowed by the sender. Affected file silcd/packet_receive.c.
516 Added the ID type as CUMODE_CHANGE notify type as argument
517 to the `notify' client operation. Affected files are
518 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
520 * Added function silc_client_add_server to the client library.
521 Added support for resolving also channel and server info when
522 received unknown entity in notify packet. Affected files are
523 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
525 * Added function silc_command_get_status to return the command
526 status from the command reply's argument payload. Affected files
527 are lib/silccore/silccommand.[ch].
529 * Added check for KICKED notify type that the kicking is
530 allowed by the client. Affected file silcd/packet_receive.c.
532 * Created function silc_get_input which can be used to get input
533 (echo on or off) from user on command line. Affected files are
534 lib/silcutil/silcutil.[ch].
536 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
538 * Optimized silc_server_packet_relay_to_channel function.
539 Added new function silc_channel_message_payload_encrypt which
540 can be called directly if channel message payload needs to
541 be encrypted and is already encoded (no need to call _encode
542 function). Packet relaying is now done by router without any
543 extra memory allocations. Affected files are
544 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
547 * Fixed the INVITE notify handling. It took wrong arguments
548 as invite list and invite delete. Affected file is
549 silcd/packet_receive.c.
551 * Added check for TOPIC_SET notify type that the topic change is
552 allowed by the client. Affected file silcd/packet_receive.c.
554 * Added check for INVITE notify type that inviting is allowed by
555 the client. Affected file silcd/packet_receive.c.
557 * Changed the silc_server_client_on_channel to return the
558 SilcChannelClientEntry as well. Moved the function
559 silc_server_check_cmode_rights to server_util.[ch].
560 Affected files are silcd/server_util.[ch], silcd/command.c.
562 * Added function silc_server_check_umode_rights to check whether
563 changing client's user mode is allowed. Added check for
564 UMODE_CHANGE notify type that the umode change is allowed
565 by the client. Affected files are silcd/server_util.[ch],
566 silcd/packet_receive.c and silcd/command.c.
568 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
571 ID length. It ignored that ID can be IPv6 based as well.
572 Affected file lib/silccore/silcpacket.h.
574 * Fixed the silc_id_id2str and silc_id_str2id to take the
575 IPv6 address offset's into consideration. Affecte file is
576 lib/silccore/silcid.c.
578 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
580 * Fixed the internal Unix scheduler functions to check for
581 NULL context they may receive. The affected file is
582 lib/silcutil/unix/silcunixschedule.c.
584 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
586 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
587 can specify different directory with --home command line
588 parameter. Affected files irssi/src/silc/core/client_ops.c,
591 * SILC-specific commands aren't now executed if the active server
592 isn't of SILC-type, so there won't be problems with having
593 IRC and SILC protocol support in same client. Affected files
594 irssi/src/silc/core/silc-channels.c, silc-servers.c,
597 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
599 * Improved the signal support in SILC Schedule. Added new
600 function silc_schedule_signal_call which is used by application
601 to mark a signal to be called. It is now safe to perform
602 any kind of tasks in signal callbacks since it is guaranteed
603 that the application specified signal callback is called
604 after the signal is over. Affected files are
605 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
607 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
609 * Added `name' field to SilcChannelPrivateKey to represent
610 application given name for the key. Moved also the context from
611 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
612 Added the `name' argument also to the function
613 silc_client_add_channel_private_key.
615 Added function silc_client_current_channel_private_key to set the
616 current channel private key in use.
618 Added "change" command to KEY command which can be used to change
619 the current channel private key. Bound the command also to
622 Also affected files lib/silcclient/client_channel.c,
623 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
625 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
627 * Added silc_rng_get_byte_fast function in to the
628 lib/silccrypt/silcrng.[ch].
630 * Changed the interface of silc_packet_assemble and the
631 silc_packet_send_prepare. If silc_packet_assmble is now
632 called the application does not call silc_packet_send_prepare
633 because the library will call it automatically. These
634 interfaces now also return a reference to the outgoing buffer
635 which includes the assembled packet, which the application can
636 use to encrypt the packet.
638 Affected files are lib/silccore/silcpacket.[ch],
639 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
640 silcd/packet_send.c, server_backup.c and packet_receive.c.
642 * Fixed a packet sending bug on very high load, where outgoing
643 packet queue wasn't handled correctly and packets got corrupted.
644 Affected files are lib/silcutil/*/silc*sockconn.c,
645 lib/silcclient/client.c and silcd/server.c.
647 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Added macro SILC_PACKET_DATALEN which can be used during
650 packet assembling to check whether the data to be added to
651 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
652 len is truncated until it fits it.
654 Added checks for maximum length of channel message payload and
655 private message payload also.
657 Added checks for maximum packet length in server and in
660 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
661 lib/silcclient/client.c, lib/silccore/silcchannel.c and
662 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
663 lib/silcclient/client_prvmsg.c.
665 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Added silc_server_packet_queue_purge call to the
668 silc_server_disconnect_remote to assure that all data in the
669 queue before disconnecting is sent to the network. Affected
672 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Added the deleting of server's own ID cache entry to the
675 silc_server_free function. Free also everything else that
676 has been allocated in silc_server_init. The affected file
679 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
681 * Added functions silc_parse_version_string, silc_version_to_num,
682 and silc_ske_parse_version to parse SILC protocol style version
683 strings. Affected files lib/silcutil/silcutil.[ch] and
684 lib/silcske/silcske.[ch].
686 * Added new configuration params: version_protocol, version_software
687 and version_software_vendor to specify what version the remote
688 host must at least be to be able to connect to server. The vendor
689 string can be regex matched too. Added new function
690 silc_server_connection_allowed to check maximum number of allowed
691 connections, and allowed versions for incoming connections.
692 Affected files are silcd/server.c, server_util.[ch] and
695 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
697 * Added preliminary support for signals in scheduler. The
698 signals we care about are now blocked always when the scheduler
699 is locked. This way we can synchronise the use of signal with
700 scheduler. It is guaranteed that when signal occurs the scheduler
701 is not locked, and thus new tasks can be safely added to the
704 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
705 to silc_schedule_internal_init and silc_schedule_internal_uninit.
706 Added new platform specific routines
707 silc_schedule_internal_signals_[un]block and
708 silc_schedule_internal_signal_[un]register.
710 Added new functions to SILC Schedule API:
711 silc_schedule_signal_[un]register. Each signal that application
712 is going to use should be registered to the scheduler.
714 Affected files are lib/silcutil/silcschedule.[ch],
715 lib/silcutil/*/silc*schedule.c.
717 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
719 * Check for unauthenticated client and server in the
720 silc_server_new_client and silc_server_new_server functions.
721 Affected file silcd/packet_receive.c.
723 * Added function silc_string_is_ascii to check whether given
724 string is 7-bit ASCII string. Affected files are
725 lib/silcutil/silcutil.[ch].
727 * Added function silc_id_is_valid_server_id into the
728 silcd/serverid.c and added checking for valid Server ID's in
729 silc_server_new_server. The Server ID must always be based
730 on the server's public IP address.
732 * Added logging of DISCONNECT packet message in the server.
733 Affected file silcd/server.c.
735 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
737 * Changed all library interfaces that use Global RNG to also
738 accept SilcRng as argument. Affected files are
739 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
740 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
741 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
742 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
745 * Added function silc_pkcs_generate_key to the
746 lib/silccrypt/silcpkcs.[ch] for applications so that they
747 don't need to do pkcs->pkcs->init calls anymore.
749 * Remove SilcSocketConnection from the SFTP API since it really
750 wasn't needed there. The application has the information
751 saved in its contexts anyway and the SFTP layer doesn't need
752 know about it. Affected files lib/silcsft/silcsftp.h and
753 lib/silcsftp/sftp_[server/client].c.
755 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
756 The SilcSimContext is not SilcSim.
758 * Fixed possible buffer overflows in silc_id_render in the
759 lib/silcutil/silcutil.c.
761 * On EPOC the global crypto module lists are not used at all
762 in the crypto library. Added support for using the constant
763 algorithm list on EPOC. Affected files are
764 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
767 * Fixed the handling of third parameter of KICKED notify, since
768 it was mistakenly updated to SILC Protocol 1.0 even though it
769 is to be included in 1.1. Since it is not in 1.0 it is not
770 mandatory, and this fix now handles it only if it is provided,
771 and it is not error if it is not provided. Affected file
772 lib/silcclient/client_notify.c.
774 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
776 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
777 client. Affected file irssi/src/silc/core/client_ops.c.
779 * Merged with Irssi 0.8.4 from irssi.org CVS.
781 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
783 * Check for valid socket connection in client entries before
784 sending any messages. Fixes a crash, but doesn't fix some
785 other underlaying bug that is lurking there. Affected
786 file silcd/packet_send.c.
788 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
790 * $usermode, $cumode and $cumode_space expandos shouldn't do
791 anything with non-SILC server records. Affected file
792 irssi/src/silc/core/silc-expandos.c
794 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
796 * Fixed the silc_net_check_[host/local]_by_sock to support
797 IPv6 bound sockets as well. Now they can return IPv6 addresses
798 as well. Affected file lib/silcutil/silcnet.c.
800 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
801 Affected lib/silcutil/unix/silcunixnet.c.
803 * Fixed ID rendering (at least on some platforms, not NetBSD)
804 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
806 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
808 * Added silc_hash_public_key and silc_hash_public_key_compare
809 functions to be used with SilcHashTable. They can be used to
810 hash public keys and compare public keys in hash table. Affected
811 file lib/silcutil/silcutil.[ch].
813 * Added support for specifying multiple public keys for Client
814 connection section in server configuration file. This makes it
815 possible to accept multiple public keys from same host, or to
816 make a section that accepts any incoming host, and have the
817 accepted public keys listed in the section.
819 Added functions silc_sever_[find/get]_public_key, added the
820 support for this actually to all connection sections but only
821 the Client section is currently allowed to specify multiple
824 Affected files are silcd/server.c, server_internal.h,
825 command.c, protocol.c, server_util.[ch], packet_receive.c.
827 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
829 * Merged Irssi 0.8.2 from irssi.org CVS.
831 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
833 * If silc_debug is TRUE, also output standard logging messages
834 to stderr with the debug output.
836 Made silc_log_reset_all() flushing all channels before returning.
837 Also fixed some documentation typos.
839 Affected files are lib/silcutil/silclog.[ch].
841 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
843 * Fixed the server to check correctly the amount of connections
844 from single host, by checking also the type of the connection.
845 Fixed also the comparison of number of connections and number
846 of allowed connections. Affected files are silcd/server.c,
849 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Fixed the USERS command reply to save the user's mode on the
852 channel as well. Fixed JOIN command reply to check whether a
853 client is on channel already and not join it twice. Affected
854 file lib/silcclient/command_reply.c.
856 * Added new file silc-expandos.c into irssi/silc/core/ to return
857 various stuff for various signal for the statusbar etc. updating.
858 Now Irssi SILC client prints channel user modes etc. on the
861 * The user mode (like server/router operator changes) is now shown
862 on the Irssi SILC client's statusbar. The affected files are
863 irssi/src/silc/core/client_ops.c, silc-expandos.c.
865 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
867 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
868 to SILC_SCHEDULE_[UN]LOCK macros.
870 * Added more error printing to logs in server code. Affected
871 files silcd/server.c and silcd/protocol.c.
873 * Fixed -S option parsing in Irssi SILC Client. Affected file
874 irssi/src/silc/core/silc-core.c.
876 * Added silc_buffer_alloc_size function. Affected file is
877 lib/silcutil/silcbuffer.h.
879 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
881 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
882 constants. Affected files in
883 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
886 * Changed the internal SFTP Memory FS table to const. Affected
887 file lib/silcsftp/sftp_fs_memory.c.
889 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Fixed the buffer formatting and unformatting routines to
892 check the size of 64 bits types with sizeof(). Affected
893 file is lib/silcutil/silcbuffmt.c.
895 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
897 * Removed 0.6.x backwards support.
899 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * Changed all integer type names:
902 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
903 to avoid collisions with other libraries using same type names
906 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Added `prefer_ipv6' argument to the functions
909 silc_net_gethostbyname[_async]. If it is TRUE it will return
910 IPv6 address over IPv4. If FALSE IPv4 address is returned
911 even if IPv6 address was found. Affected files
912 lib/silcutil/silcnet.[ch].
914 * Added support silc_net_create_connection[_async] to fallback
915 to IPv4 address if IPv6 address could not be used (like if
916 it doesn't work on a specific system). Affected file in
917 lib/silcutil/unix/silcunixnet.c.
919 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
921 * Added silc_schedule_reinit function to do the enlarging
922 of the max tasks handling capabilities of the scheduler.
923 Affected files lib/silcutil/silcschedule.[ch].
925 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
927 * Added automatic extern "C" { ... } for C++ compilers so the
928 application does not need to define them. Affected file
929 includes/silcincludes.h.
931 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
932 old name went against naming convention. Applications now
933 include "silcclient.h" instead of "clientlibincludes.h".
934 Removed includes/clientlibincludes.h, it is redundant now.
936 * Renamed includes/version.h to silcversion.h.
938 * Added really preliminary support for OS/2 into the util
939 library. Only thread & mutex API is implemented, others
940 are still to be implemented. Created the lib/silcutil/os2/
941 directory. Created also file includes/silcos2.h.
943 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
945 * Added preliminary BeOS support into the util library.
946 Created lib/silcutil/beos/, and implemented all the needed
947 functions to support SILC on BeOS. Created also file
950 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
952 * Added proper initializations to silc's irssi code, so it's
953 now possible to load it as module. Affected files
954 irssi/src/silc/core/silc-core.c,
955 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
957 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
959 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
962 * Fixed the silcdoc document generator to correct generate
963 docs from all kinds of filenames. Affected files are
964 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
966 * ROBOdoc documented lib/silcutil/silcmemory.h.
967 Added also new function silc_memdup.
969 * Removed lib/silcutil/silcbufutil.h and moved those routines
970 to the lib/silcutil/silcbuffer.h.
972 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
974 * Added `user_count' to the SilcChannelEntry which now tells the
975 number of users on the channel. The user count is now saved
976 in normal server of global channels as well. Affected files
977 silcd/server.c, idlist.h, packet_receive.c and command.c.
979 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
980 include file utility functions.
982 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
983 instead of calling directly OS routines.
985 * Fixed NICK change printing in Irssi SILC Client. Fixed
986 KICKED notify printing in Irssi SILC Client. Affected file
987 irssi/src/silc/core/client_ops.c.
989 * Fixed a NICK change bug in client library, to not recreate the
990 client_entry->channels hash table everytime nick is changed.
991 Affected file lib/silcclient/client.c.
993 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
995 * ROBOdoc documented the lib/silcske/silcske.h, and improved
996 the SKE interface a bit.
998 * Fixed padding problem in PKCS#1. The padding was not actually
999 random since the random number generator was used incorrectly.
1000 This security bug affects only when encrypting with PKCS#1, and
1001 it is not currently used at all in SILC. SILC only use signing
1002 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1004 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1006 * Rewrote the notify handling in Irssi SILC client to not call
1007 the events as signals. Fixes problems with Perl support.
1008 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1010 * Send the auto-nicking NICK command in client library with
1011 little timeout after connecting. The affected file is
1012 lib/silcclient/client.c.
1014 * Added following new config file settings:
1015 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1016 key_exchange_timeout, conn_auth_timeout, connections_max,
1019 Implemented all the new config settings handling in the server.
1021 Optimized the use of SKE Mutual flag usage. Use it only
1022 if connection authentication protocol is not based in public
1025 Renamed all SilcServerConfigSection* to SilcServerConfig*
1026 to have a bit shorter names.
1028 Affected files silcd/serverconfig.[ch], server.[ch], and
1031 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1033 * Cleaned up the listening sockets code, preparing for the rehash
1034 support. Affected file is silcd/server.c.
1036 * Fixed some output messages. Affected files are silcd/silcd.c,
1039 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1052 * Removed param_name member from client, server, and router
1053 section structs, now identifying the param directly.
1055 Added CONFIG_FREE_AUTH macro in config file parsing.
1057 Affected files are silcd/serverconfig.[ch].
1059 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1061 * Fixed command line parameter handling. All SILC initialization
1062 is now done in silc_core_init() which also fixes autoconnecting
1065 Affected files irssi/src/silc/core/silc-core.c,
1066 irssi/src/fe-text/silc.c.
1068 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1070 * Added new configuration options and blocks:
1071 keepalive_secs, reconnect_count, reconnect_interval,
1072 reconnect_interval_max, reconnect_keep_trying and
1073 require_reverser_lookup. Added ConnectionParam block, and
1074 implemented the connection parameters when connecting as
1075 initiator and when accepting connections as responder.
1077 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1078 whether given configuration value has been given already.
1080 Affected files silcd/serverconfig.[c], server.[c].
1082 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1083 algorithm parts and created new file silcalgs.conf, that
1084 is now included from the example_silcd.conf.in.
1086 * Optimized the silc_server_connect_to_router_second to take
1087 the connection configuration object from the SilcServerConnection
1088 object instead of finding it during the connecting phase.
1089 Added the configuration object to SilcServerConnection struct.
1090 Affected files silcd/server_internal.h, server.c.
1092 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1094 * Add the client on channel after it was resolved at the
1095 channel message receiving, and it was not already on the
1096 channel. Affected file lib/silcclient/client_channel.c.
1098 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1112 * Added new Passphrase and Publickey authentication methods to
1113 config file, allowing both public key and passphrase based
1114 authentication to be set at the same time.
1116 Added `prefer_passphrase_auth' setting in config file which
1117 can be used to set to prefer passwd auth if both passwd and
1118 public key is set. If not set, public key is preferred.
1119 This has effect only when being initiator (responder will try
1122 Added support for authentication with passphrase and public key
1123 at the same time. The passphrase is tried first always since
1124 it is faster to check.
1126 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1128 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1130 * Merged the new SILC Config library, with the server parsing

1155 Payload. Affected file lib/silccore/silcchannel.c.
1157 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1158 as header filenames.
1160 * Removed lib/silcclient/README and created HTML file
1161 lib/silcclient/silcclient_using.html, which is now included
1162 as part of Toolkit documentation.
1164 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1166 * Fixed CUMODE_CHANGE notify handling to change the mode of
1167 correct client. Affected file lib/silcclient/client_notify.c.

1174 * Fixed the file transfer's key agreement payload to include
1175 zero port also if the hostname is NULL because it could not
1178 Call file transfer monitor callback now also if error occurs
1179 during key agreement protocol.
1181 Changed the silc_client_file_send interface to return the
1182 SilcClientFileError instead of session id. The session ID
1183 is returned into pointer provided as argument.
1185 Check that the file exists locally before sending the
1186 file transfer request at all.
1188 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1190 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1191 error than can occur while key agreement protocol. Affected
1192 file lib/silcclient/silcapi.h.

1198 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1199 SILC_LOG_WARNING to give out Warning and not Error. Affected
1200 file lib/silcutil/silclog.c.
1202 * Fixed the channel message payload decryption in the function
1203 silc_channel_message_payload_decrypt to not modify the original
1204 buffer before it is verified that the message decrypted
1205 correctly. Otherwise, next time it is called with correct
1206 channel key it won't encrypt since the payload is corrupted.
1207 Affected file lib/silccore/silcchannel.c.
1209 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1219 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1221 * Fixed a bug in hash table internal routine for traversing
1222 the table with foreach callback. The current entry may
1223 become invalid in the callback but it was referenced after
1224 the callback returned.
1226 Do not allow auto rehashing of hash table during the
1227 silc_hash_table_foreach operation, for same reasons as it is
1228 not allowed for SilcHashTableList. Affected files are
1229 lib/silcutil/silchashtable.[ch].
1231 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1233 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1234 Win32 DLL. extern's in header files are now declared with
1237 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1239 * Fixed private message handling. It used some old code that
1240 caused the client to crash. Affecte file is
1241 lib/silcclient/client_prvmsg.c.
1243 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1245 * Added function silc_client_add_channel,
1246 silc_client_replace_channel_id, and removed functions
1247 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1248 from client library.
1250 * Added cross reference of the joined channels to the
1251 SilcClientEntry, and changed the SilcChannelEntry's
1252 users list to SilcHashTable. The affected files are
1253 lib/silcclient/idlist.[ch].
1255 * Fixed a bug in hash table tarversing. While the hash table
1256 is traversed with SilcHashTableList the table must not be
1257 rehashed. It is now guaranteed that auto rehashable tables
1258 are not rehashed while tarversing the list. Also defined that
1259 silc_hash_table_rehash must not be called while tarversing
1260 the table. Added function silc_hash_table_list_reset that must
1261 be called after the tarversing is over. The affected files are
1262 lib/silcutil/silchashtable.[ch].
1264 * Changed all hash table traversing to call the new
1265 silc_hash_table_list_reset in server and in client library.
1267 * Added function silc_client_on_channel to return the
1268 SilcChannelUser entry if the specified client entry is joined
1269 on the specified channel. This is exported to application as
1270 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1272 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Fixed founder regaining problem with JOIN command on normal
1275 server. The notify for mode change must be sent always and
1276 not only if !cmd->pending. Affected file silcd/command.c.
1278 * Fixed the WHOWAS command's reply sending to support the
1279 lists correctly. Affected file silcd/command.c.
1281 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1283 * When sending JOIN command to router for processing the
1284 sender's old command identifier was not saved back to the
1285 sender's command context, fixed now. The affected file is
1288 * Create the key in JOIN command of the router did not return
1289 the channel key, added check for this. Affected file is
1292 * Fixed a channel ID update bug in JOIN command reply. Do
1293 not directly upgrade the ID but call the function
1294 silc_idlist_replace_channel_id if the ID was changed.
1295 Affected file silcd/command_reply.c.
1297 * Fixed memory leaks from command calling if it would fail.
1298 Affected file silcd/command.c.
1300 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1302 * Applied patches from cras:
1304 Memory leak fixes around libaries, irssi window resize fix,
1305 new silclist.h and silcdlist.h, all extern inline changed to
1308 * Removed dotconf from lib/dotconf, not needed anymore.
1310 * Removed TRQ from lib/trq, not needed anymore.
1312 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1313 with server connections. Later this will be configurable
1314 in config file after new config file is done. Affected file
1317 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1319 * Fixed a crash in server related to channel announcements.
1320 Affected file silcd/server.c.
1322 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1324 * Fixed memory leaks in silc_server_create_new_channel*
1325 functions. Affected file silcd/server.c.
1327 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1328 which ID was changed. This way the router will send the
1329 user list for the channel again, and server won't be in
1330 desync in some rare circumstances. Affected file is
1331 silcd/packet_receive.c.
1333 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1335 * Check for NULL socket pointer in the function
1336 silc_server_packet_send_to_channel_real. Affected file
1337 silcd/packet_send.c.

1344 * Fixed some header addition to Toolkit distribution in
1345 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1347 * Added lib/silcclient/client_ops_example.h as an template
1348 file for application programmers to quickly start using
1349 the SilcClientOperation functions in their application.
1350 Updated the lib/silcclient/README as well to tell about this
1351 nice file made available.
1353 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1355 * Call silc_server_remove_from_channels when removing client
1356 entry when NO_SUCH_CLIENT_ID was received. Affected file
1357 is silcd/command_reply.c.
1359 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Added server & router operator statistics updating. Affected
1362 file silcd/packet_receive.c and silcd/command.c.
1364 * Fixed the SERVER_SIGNOFF notify handling on normal server
1365 not to save the history information for clients. Same was
1366 fixed earlier in remove_clients_by_server function, but not
1367 here. Affected file silcd/packet_receive.c.
1369 * Raised the default connection-retry count from 4 to 7 in
1370 server. Affected file silcd/server.h.
1372 * Cancel any possible reconnect timeouts when we start the
1373 key exchange. Affected file silcd/server.c.
1375 * Do not reconnect on connection failure when SCONNECT was
1376 given. Affected files silcd/server.[ch].
1378 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1380 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1382 * Fixed the NICK command to always give the unformatted
1383 nickname to the one giving the NICK command. If unformatted
1384 nickname is cached already it will be formatted and the
1385 local entry will always get the unformatted nickname.
1386 Affected file lib/silcclient/idlist.c.
1388 * Fixed some double frees from client library commands.
1389 Affected file is lib/silcclient/command.c.
1391 * Fixed CUMODE command in server to assure that no one can
1392 change founder's mode than the founder itself, there was a
1393 little bug. Affected file silcd/command.c.
1395 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1397 * Removed the SilcClientCommandDestructor from the client
1398 libary, it is not needed anymore. Affected files are
1399 lib/silcclient/silcapi.h, command[_reply].[ch],
1400 client_notify, idlist.c.
1402 * Fixed GETKEY command to first resolve client, and then
1403 resolve the server only if the client was not found, instead
1404 of resolving both at the same time. Affected file is
1405 lib/silcclient/command.c.
1407 * Added silc_client_start_key_exchange_cb and lookup the
1408 remote hostname and IP address before starting the key
1409 exchange with server. The affected file is
1410 lib/silcclient/client.c.
1412 * The server's public key is now saved using the IP address
1413 of the server and not the servername for the filename.
1414 The hostname public key filename is checked as an fall back
1415 method if the IP address based filename is not found.
1417 Fixed the GETKEY command to save the fetched server key
1418 in correct filename.
1420 Print the remote server's hostname now when new key is
1421 received during connection process. Affected file is
1422 irssi/src/silc/core/client_ops.c.
1424 * Return always our own public key to the client if it asks
1425 for it with GETKEY command. Affected file silcd/command.c.
1427 * Removed the use_auto_addr variable from default config
1428 file since it was in wrong section. Affected file is
1431 * Fixed TOPIC_CHANGE notification to not route it when it
1432 was sent using silc_server_send_notify_to_channel function.
1433 Affected file silcd/command.c.
1435 * Fixed silc_server_send_notify_kicked to send the kicker's
1436 Client ID also, it was missing. Affected files are
1437 silcd/command.c, silcd/packet_send.[ch].
1439 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1441 * Do not save client history information in SERVER_SIGNOFF.
1442 Fixes the bug in normal server that it does not detect
1443 the client becoming valid after the server becomes back
1444 online. Affected file silcd/server_util.c.
1446 * Added `sock_error' field into the SilcSocketConnection
1447 context. When error occurs during socket operation (read
1448 or write) the error is saved. Added also new function
1449 silc_socket_get_error to return human readable socket error
1450 message. Affected files are lib/silcutil/silcsockconn.[ch],
1451 lib/silcutil/unix/silcunixsockconn.c, and
1452 lib/silcutil/win32/silcwin32sockconn.c.
1454 * The server now prints the socket error message in the
1455 signoff for client. Affected file silcd/server.c.
1457 * Fixed the `created' channel information sending from router
1458 to server in JOIN command. Checks now whether the channel
1459 really was created or not and set it according that.
1461 Fixed the JOIN command to use the client entry's current
1462 ID during the joining procedure instead of the one it sent
1463 in the command (it is checked though), since it can change
1464 between the packet processing and command processing, and
1465 would just case unnecessary pain in the client end. Affected
1466 file silcd/command.c.
1468 * Fixed a channel key payload sending to use correct channel
1469 ID when the server was forced to change the channel's ID by
1470 router. Router sent the key payload with the old Channel ID.
1471 Affected file silcd/packet_receive.c.
1473 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1475 * Call silc_server_save_channel_key only if the key payload
1476 was provided in the JOIN command's command reply. Affected
1477 file silcd/command_reply.c.
1479 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1481 * Fixed silc_mp_sizeinbase to return the value correctly with
1482 MPI. Affected file lib/silcmath/mp_mpi.c.
1484 * Fixed the stop_server signal to correctly stop the scheduler
1485 and gracefully stop the server when SIGTERM or SIGINT signals
1486 are received. Affected file silcd/silcd.c.
1488 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1490 * Simple handling of TERM and HUP signals. Also added some log
1491 flushing call around. Affected file is
1494 * Fixed small bugs in silclog.c. Now buffering output will take
1495 effect after 10 seconds since startup: This will ensure that
1496 no important startup messages are lost. Also output redirection
1497 will preserve original format ([Date] [Type] message).
1498 Affected file is lib/silcutil/silclog.c.
1500 * Added two options to the config file, in the logging section:
1501 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1502 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1504 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1506 * Do not print the warning about log files not being initialized
1507 more than once to avoid excess logging. Affected file is
1508 lib/silcutil/silclog.c.
1510 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1511 the SIM copying in make install in Makefile.am.pre.
1513 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1515 * Rewritten silclog APIs. Globally interesting changes follows:
1516 silc_log_set_files() changed to silc_log_set_file().
1517 silc_log_set_callbacks() changed to silc_log_set_callback().
1518 ROBOdoc documented silclog header file.
1519 SilcLogCb now returns bool to wether inihibit the default
1520 handler or not (to keep the old behaviour return always TRUE).
1521 The new APIs should also fix the problem of the
1522 silcd_error.log file that was written in the current directory.
1525 Log files streams will remain opened after silc_log_set_file()
1526 call, means less CPU usage notably on high traffic servers.
1527 File streams are now full buffered, and flushed to the disk
1528 every 5 minutes, lesses HD activity and CPU usage.
1529 Messages can be redirected, allowing admins to configure
1530 one single logfile for all server messages.
1531 the silc_log_quick global variable to activate fast-logging.
1532 Affected files lib/silcutil/silclog.[ch]
1534 * Changed some code to conform new silclog APIs. Affected
1535 files are doc/example_silcd.conf.in, silcd/server.c
1536 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1539 * Fixed a memory leak that could occur in some situations.
1540 Affected file silcd/serverconfig.c.
1542 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1544 * Added the silc_client_del_client to remove the client from
1545 all channels as well. Affected file lib/silcclient/idlist.c.
1547 * Fixed the client library to correctly remove the client
1548 from all channels when the client entry is being destroyed.
1549 Affected file lib/silcclient/client_notify.c, command.c.
1551 * Added auto-nicking support to the client library. If the
1552 applicatio now sets client->nickname it will be sent to the
1553 server after connecting by the library. This way for example
1554 SILCNICK (or IRCNICK) environment variables will have effect
1555 and always change the nickname automatically to whatever
1556 it is wanted. Affected file lib/silcclient/client.[ch].
1558 * Renamed silc_server_command_bad_chars to the
1559 silc_server_name_bad_chars and moved it to the
1560 silcd/server_util.[ch]. Added also new function
1561 silc_server_name_modify_bad to return nickname that
1562 includes bad characters as new nickname without those
1563 bad characters. This check and modify is now used in
1564 silc_server_new_client when the username is initially set
1565 as nickname, so it must be checked to be valid nickname.
1566 Affected file silcd/packet_receive.c.
1568 * The nickname length is now taken from the packet for real
1569 and not trusted to strlen() since it clearly can return
1570 wrong length for nickname including bad characters. This
1571 also applies to channel names. Affected file silcd/command.c.
1573 * Removed the lib/silcsilm/modules directory. Modules are now
1574 compiled into the lib/silcsim. Fixed the copying of the
1575 modules to follow symbolic links in Makefile.am.pre.
1577 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1579 * Fixed silc_string_regexify list creation. Fixes bugs with
1580 BAN and INVITE commands in server. The affected file is
1581 lib/silcutil/unix/silcunixutil.c.
1583 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Removed the command destructor entirely from the server's
1586 command and command reply routines. It is not needed, and
1587 its usage was buggy and caused crashes. Affected files are
1588 silcd/command[_reply].[ch].
1590 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Cancel protocol and NULL sock->protocol if timeout
1593 occurred during protocol. Affected file silcd/server.c.
1595 * Cancel protocol timeouts always before calling the final
1596 callback, to assure that after final callback is called
1597 no other state will be called for the protocol anymore.
1598 Affected file silcd/protocol.c.
1600 * Print error log if incoming connection configuration could
1601 not be found. Affected file silcd/server.c.
1603 * Fixed JOIN command to correctly save the founder mode
1604 to the client on normal SILC server, when the channel
1605 was created by the router. Affected file silcd/command.c.
1607 * Fixed LIST command (hopefully) to send correct reply
1608 packets. Affected file silcd/command.c.
1610 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * The silc_packet_receive_process now returns FALSE if the
1613 read data was invalid packet, and TRUE if it was ok.
1615 The server now checks that if unauthenticated connection
1616 sends data and its processing fails the server will close
1617 the connection since it could be a malicious flooder.
1619 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1621 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Make sure the warning about error opening a log file is
1624 printed only once and not everytime it fails (produces
1625 too much useless log). Affected file lib/silcutil/silclog.c.
1627 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1629 * Made the silc_server_daemonise() function more readable.
1630 Affected file silcd/server.c.
1632 * Pid file is now optional, the user may comment it out from
1633 the config file. Removed define SILC_SERVER_PID_FILE, we
1634 don't need a default any longer. Affected file
1635 configure.in.pre, lib/Makefile.am.pre.
1637 * Make some use of the pid file. The server now dies at startup
1638 if it detects a valid pid file on his path. The server would
1639 die anyway in this circumstance, because of the bind() failure.
1640 Affected file silcd/silcd.c.
1642 * No longer compiling lib/dotconf.
1644 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Fixed JOIN command parsing not to crash. Affected file
1647 lib/silcclient/command.c.
1649 * Fied the NICK_CHANGE notify to add the new client entry
1650 even it is resolved. This removes an <[unknown]> nick
1651 thingy bug in the client. Affected file is
1652 lib/silcclient/client_notify.c.
1654 * Do not try to allocate 0 bytes (efence does not like it)
1655 in lib/silccore/silccomand.c when encoding payload.
1657 * Do not take IRCNICK as nickname in Irssi SILC client since
1658 it is not possible to set nickname before hand connecting
1659 the server (TODO has an entry about adding auto-nicking
1662 * Changed the silc_server_command_pending to check whether
1663 there already exists an pending entry with the specified
1664 command, command identifier and pending callback. This is
1665 to fix IDENTIFY and WHOIS related crashes that may register
1666 multiple pending commands with same identifier. Affected
1667 file silcd/command.c.
1669 * Fixed the server to reconnect to the router even if it
1670 was already reconnecting and EOF was received. This to
1671 fix a possibility that the server wouldn't ever try to
1672 auto-reconnect to the router. Affected file silcd/server.c.
1674 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Fixed the server's password authentication to use the
1677 length of the locally saved password, and not the one
1678 sent in the packet. Affected file silcd/protocol.c.
1680 * Fixed same password authentication problem in the
1681 Authentication Payload handling routines in
1682 lib/silccore/silcauth.c.
1684 * Yet another password authentication problem fixed with
1685 channel password handling in silcd/command.c.
1687 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * If first character of string in silc_parse_userfqdn is '@'
1690 then do not parse it. Affected file is
1691 lib/silcutil/silcutil.c.
1693 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Fixed minor bug in IDENTIFY command reply sending, which
1696 caused various weird problems during JOIN when it was
1697 resolving names for users. Affected file silcd/command.c.
1699 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Fixed the IDENTIFY command reply sending to chech better valid
1702 clients. It was possible to send incomplete list of replies.
1703 Affected file silcd/command.c.
1705 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Added silc_client_command[s]_[un]register functions now to
1708 dynamically register the commands in client library. Removed
1709 the static table of commands. This allows the client library
1710 to call commands without causing the application to know about
1711 what commands library has called.
1713 Removed the INFO command reply kludge to detect when the command
1714 was called by library. Now library use its own command reply
1715 function for INFO command.
1717 Added function silc_client_command_call to call a command.
1718 Application can use it to call command, not access the structure
1721 Now all commands that are sent by the client library (not
1722 explicitly sent by application) use own command reply functions.
1724 Affected files around lib/silcclient/ and in
1725 irssi/src/silc/core/.
1727 * Fixed the WHOIS command reply sending to chech better valid
1728 clients. It was possible to send incomplete list of replies.
1730 Fixed the WHOIS and IDENTIFY to send the request to router
1731 if normal server did not do it and did not find any results.
1733 Affected file silcd/command.c.
1735 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Moved the internal data from SilcClient context into its
1738 own file, not accesible to application. Affected files
1739 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1740 and other files in client library.
1742 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Added doc/examples installation target in Makefile.am.pre.
1747 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1750 commands the found client entry will be removed from the
1751 cache, after notifying application about the error. Affected
1752 file lib/silcclient/command_reply.c.
1754 * Changed the /MSG to check for exact nickname user gave, and
1755 not let `nick' match `nick@host' if it is only one found. Now,
1756 user must type the exact nickname (like nick@host2) even if
1757 there are no more than one same nicks found. This is to avoid
1758 a possibility of sending nickname to wrong nickname since
1759 `nick' could match `nick@host'. Affected file is
1760 irssi/src/core/silc-servers.c.
1762 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Do not print "you are now server operator" or similar when
1765 giving /away command. Affected files are
1766 irssi/src/silc/core/client_ops.c, silc-servers.h.
1768 * Made the silc_server_command_pending_error_check to send
1769 the same command reply payload it received back to the
1770 original sender of the command. This way all arguments
1771 that was received by the server will be received by the
1772 client too. Affected file silcd/command.c.
1774 * Added the silc_idcache_add to return the created cache entry
1775 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1777 * Add global clients to expire if they are not on any channel.
1778 This is because normal server will never know if they signoff
1779 if they are not on any channel. The cache expiry will take
1780 case of these entries. This is done by normal servers only.
1781 The affected files are silcd/command_reply.c,
1782 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1784 * If server receives invalid ID notification for WHOIS or
1785 IDENTIFY and the ID exists in the lists, it is removed.
1786 Affected file silcd/command_reply.c.
1788 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1789 in client then client entry that it matches is searched and
1790 the nickname is printed on the screen for user. Affected
1791 file irssi/src/silc/core/client_ops.c.
1793 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Use cache entry expire time in the LIST command reply to
1796 purge old entries from the cache after the LIST command
1797 reply has been received. This way we don't have non-existent
1798 entries in the cache for too long. Affected file is
1799 silcd/command_reply.c.
1801 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1803 * If we are normal server, and we've not resolved client info
1804 in WHOIS or IDENTIFY from router, and it is global client,
1805 we'll check whether it is on some channel. If it is not
1806 then we cannot be sure about its validity and will resolve it
1807 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1808 file silcd/command.c.
1810 * Search channel by name (if possible) rather than by ID
1811 in IDENTIFY command's command reply. Affected file is
1812 silcd/command_reply.c.
1814 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1817 Updated specs and implemented it. Affected file silcd/command.c,
1818 silcd/packet_send.c and silcd/packet_receive.c.
1820 * Implemented the <founder auth> payload handling in the JOIN
1821 command. If provided all conditions for channel joining
1822 except requirement to provide correct passphrase can be
1823 overrided by the channel founder. Updated the protocol specs.
1824 Affected file silcd/command.c.
1826 Added support for founder auth in JOIN command in client
1827 library. Fixed the parsing of the JOIN command now to support
1828 all options as they should be. The affected file is
1829 lib/silcclient/command.c.
1831 * Optimized the WHOIS and IDENTIFY commands to send the request
1832 to router only if it includes nicknames or other names. If
1833 they include only IDs then check the local cache first before
1834 routing. Affected file is silcd/command.c.
1836 * Added channels topic announcements. Affected file is
1837 silcd/packet_receive.c and silcd/server.c.
1839 * Fixed the silc_server_send_notify_topic_set to really destine
1840 the packet to channel. Affected file silcd/packet_send.c.
1842 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1843 library. Affected file lib/silcclient/client_notify.c.
1845 * Added UMODE announcements. Affected file silcd/server.c.
1847 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * Memory leak fixes in:
1851 lib/silcutil/silcsockconn.c
1852 lib/silcske/silcske.c
1853 lib/silcske/groups.c
1855 lib/silccrypt/silcpkcs.c
1856 lib/silccore/silccommand.c
1857 lib/silccore/silcidcache.c
1862 * ROBOdoc documented the lib/silcske/groups.h file and a
1863 bit changed the interface for better.
1865 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1867 * Update the client entry context in the ID cache after
1868 nick change. Affected file lib/silcclient/command.c.
1869 Fixes the CUMODE command when regaining founder privileges,
1870 and a little WHOIS problem.
1872 * Fixed silc_net_gethostbyname to correctly call the
1873 inet_ntop. Affected file lib/silcutil/silcnet.c.
1875 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1877 * Added IPv6 support checking to the configure.in.pre, added
1878 also --enable-ipv6 option to override the check. Affected
1879 file configure.in.pre.
1881 * The silc_thread_create now calls the start function
1882 directly if threads support is not compiled in. Removes
1883 ugly #ifdef's from generic code. Affected files are
1884 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1886 * Added silc_net_gethostby[name/addr]_async to asynchronously
1887 resolve. Affected files are lib/silcutil/silcnet.[ch].
1889 * Added support for rendering IPv6 based server, client and
1890 channel IDs. Affected file lib/silcutil/silcutil.c.
1892 * Added support for creating IPv6 based server IDs. Affected
1893 file is silcd/serverid.c.
1895 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1897 * Added silc_net_gethostby[addr/name] into the
1898 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1899 routines. Added silc_net_is_ip[4/6]. Affected file is
1900 lib/silcutil/unix/silcunixnet.c. All routines that take
1901 address as argument now supports both IPv4 and IPv6 addresses.
1903 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1905 * Fixed LIST command reply sending in server. Affected file
1908 * Server now sends the kicker's client ID in the KICK notify
1909 to the kicked client. Affected file silcd/command.c.
1911 * The client library now parses the kickers client ID and
1912 UI displays it. Affected files lib/silcclient/client_notify.c
1913 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1915 * Made all payload parsing function prototypes consistent.
1916 They all take now const unsigned char * and uint32 pair as
1917 the payload data instead of SilcBuffer. Changes all around
1918 the source tree. Other unsigned char* -> const unsigned char*
1919 changes around the tree as well.
1921 * Optimized SFTP client and server packet sending not to
1922 allocate new buffer for each packet but to recycle the
1923 first allocated buffer. Affected files are
1924 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1926 * Optimized the SFTP client to use SilcList instead of
1927 SilcDList for requests, because it is faster. Affected file
1928 is lib/silcsftp/sftp_client.c.
1930 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1931 into lib/silccore/silcid.[ch].
1933 Renamed silcpayload.[ch] into silcargument.[ch].
1935 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1937 * If client entry is deleted with active key agreement
1938 session, abort the session.
1940 The silc_client_abort_key_agreement now calls the completion
1941 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1943 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1946 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Don't use __restrict in older GCC's. Affected file is
1949 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1951 * silc_net_localhost now attempts to reverse lookup the
1952 IP/hostname. Affected file lib/silcutil/silcnet.c.
1954 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1955 command. It can be used to gain founder privileges at
1956 the same time when joining the channel.
1958 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1959 kicker's client ID as well. Updated protocol specs.
1961 Defined that the server must send SILC_COMMAND_IDENTIFY
1962 command reply with error status to client who sent
1963 private message with invalid client ID.
1965 Updated the protocol specification.
1967 * Added silc_server_send_command_reply to send any
1968 command reply. Affected file silcd/packet_send.[ch].
1970 * Added silc_id_payload_encode_data to encode ID payload
1971 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1973 * The server now send IDENTIFY command reply with error
1974 status if client ID in private message is invalid. Affected
1975 file silcd/packet_receive.c.
1977 * Save the server key file with server's IP address in
1978 the filename instead of hostname. The affected file is
1979 irssi/src/silc/core/client_ops.c.
1981 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1986 * Added libtool support for compiling shared objects in
1987 lib/silcsim. Affected file configure.in.pre and
1988 lib/silcsim/Makefile.am. Original patch by cras.
1990 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1992 * Pid file configuration, and server's config file fixes
1993 patch by toma. Updated CREDITS file.
1995 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Fixed silc_client_channel_message to not try to decrypt
1998 the message twice if it resolved the destination client
1999 information. This could cause of dropping one channel
2000 message. Affected file lib/silcclient/client_channel.c.
2002 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2005 lib/silcclient/client.c. This function is used when the SILC
2006 Client is run under some other scheduler, or event loop or
2007 main loop. On GUI applications, for example this may be
2008 desired to used to run the client under the GUI application's
2009 main loop. Typically the GUI application would register an
2010 idle task that calls this function multiple times in a second
2011 to quickly process the SILC specific data.
2013 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2015 * Fixed silc_server_drop() for dropping the supplementary
2016 groups as well, this could cause a security hole on some
2019 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2024 * Write PID file after dropping privileges. Added -F option
2025 to run server on foreground. A patch by debolaz.
2026 Affected files silcd/server.c, silcd/silcd.c.
2028 * Fixed MOTD to return the MOTD file server name. Affected
2029 file silcd/command.c.
2031 * Added INFO command reply handling to the Irssi SILC Client.
2032 Affected file irssi/src/silc/core/client_ops.c.
2034 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2036 * Fixed the silc_idcache_list_* routines to really support
2037 the dynamic list. Fixes a crash. Affected file is
2038 lib/silccore/silcidcache.c.
2040 * Fixed the LIST command reply to really call LIST command's
2041 pending callbacks. Affected file silcd/command_reply.c.
2043 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Update conn->local_entry->nickname after giving NICK
2046 command. Affected file lib/silcclient/command.c.
2048 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2050 * Added the [pid] option to the silcd configuration file
2052 Affected files: serverconfig.[ch] and silcd.c
2054 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Save fingerprint in WHOIS command reply in server.
2057 Affected file silcd/command_reply.c.
2059 * Fixed NICK commands pending callback registration.
2060 Affected file lib/silcclient/command.c.
2062 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Use ++server->cmd_ident when sending commands in server,
2065 instead of random number. Affected file silcd/command.c.
2067 * Fixed GETKEY command reply to call actually GETKEY pending
2068 command callbacks. Affected file silcd/command_reply.c.
2070 * A bit stricter check for nicknames. Check for same nickname
2071 in NICK command also. Affected file silcd/command.c.
2073 * Do not call INFO command everytime client ID changes, only
2074 during first connecting. Affected file lib/silcclient/client.c.
2076 * Set the new nickname only after successful command reply for
2077 NICK command is returned by server. Affected file
2078 lib/silcclient/command.c.
2080 * Remove nicknames from nicklist during server_signoff notify.
2081 Should fix /NAMES bit more. The affected file is
2082 irssi/src/silc/core/silc-channels.c.
2084 * Added `fingerprint' field to the SilcIDListData in the
2085 silcd/idlist.h to hold the fingerprint of the client's
2088 Send the fingerprint of the client's public key in WHOIS
2091 Affected files silcd/command.c, and silcd/idlist.[ch].
2093 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2094 create fingerprint from given data.
2096 * Show the fingerprint of the client's public key in WHOIS.
2097 Affected files irssi/src/module-formats.[ch] and
2098 irssi/src/silc/core/client_ops.c.
2100 * Format the multiple same nicknames also during JOIN and
2101 NICK_CHANGE notifys. Affected file is
2102 lib/silcclient/client_notify.c.
2104 * Do not print error on screen for invalid private message
2105 payload since it can come if someone is sending private
2106 messages with wrong key. Affected file
2107 lib/silccore/silcprivate.c.
2109 * Fixed multiple concurrent /PING crash. Affected file
2110 lib/silcclient/command.c.
2112 * Changed the wrong ID encoding. All IP addresses must be
2113 in MSB first order in encoded format. They were encoded
2114 wrong and was in LSB format. Affected files are
2115 silcd/serverid.c, lib/silcutil/silcutil.c.
2117 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2119 * Call the `connect' client operation through the scheduler
2120 in case of error. Affected file lib/silcclient/client.c.
2122 * Call the `failure' client operation even if the error
2123 occurred locally during a protocol. Affected file is
2124 lib/silcclient/protocol.c.
2126 * Added support of sending LIST command to router from normal
2127 server. This way normal server can get list of all channels
2128 in the network too. Fixed the channel list sending in the
2129 server too. Affected files are silcd/command.c, and
2130 silcd/command_reply.[ch].
2132 * Added silc_server_update_channels_by_server and
2133 silc_server_remove_channels_by_server. They are used during
2134 disconnection of primary router and in backup router protocol.
2135 Affected file silcd/server_util.[ch], silcd/server.c and
2136 silcd/server_backup.c.
2138 * Fixed channel adding to global list in IDENTIFY command
2139 reply in server. Affected file silcd/command_reply.c.
2141 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * If the incoming packet type is REKEY or REKEY_DONE process
2144 that packet always synchronously. Fixes yet another MAC
2145 failed error on slow (dialup) connections. Affected file
2146 lib/silcclient/client.c and silcd/server.c.
2148 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Call check_version SKE callback for initiator too. Affected
2151 file lib/silcske/silcske.c.
2153 * Implemented fix for security hole found in the SKE that was
2154 fixed in the specification few days back; the initiator's
2155 public key is now added to the HASH value computation.
2156 Added backwards support for the old way of doing it too, for
2157 old clients and old servers. Affected file is
2158 lib/silcske/silcske.c.
2160 * Enabled mutual authentication by default in SKE. If initiator
2161 is not providing mutual authentication the responder will
2162 force it. This will provide the proof of posession of the
2163 private key for responder. The affected files are
2164 lib/silcclient/protocol.c and silcd/protocol.c.
2166 * Do not cache anymore the server's public key during SKE.
2167 We do mutual authentication so the proof of posession of
2168 private key is done, and if the server is authenticated in
2169 conn auth protocol with public key we must have the public
2170 key already. Affected file silcd/protocol.c.
2172 * Added new global debug variable: silc_debug_hexdump. If
2173 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2174 file lib/silcutil/silclog.[ch].
2176 * Fixed compilation warning due to char * -> const char *.
2177 Affected files lib/silcutil/silcnet.h, and
2178 lib/silccore/silcauth.[ch].
2180 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * Fixed CMODE command when new channel key was created. If
2183 the creation failed the old key was removed. Next time giving
2184 same command would crash the server since the old key was
2185 freed already. Affected file silcd/command.c.
2187 * Fixed the silc_server_announce_get_channels to not crash
2188 on reconnect. Affected file silcd/server.c.
2190 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Added silc_log_set_debug_string function to set a regex
2193 string to match for debug output. Only the function names,
2194 or filenames matching the given debug string is actually
2195 printed. This way it is possible to filter out those debug
2196 strings that user is not interested in.
2198 Fixed a bug in silc_string_regexify.
2200 Affected files lib/silcutil/silclog.[ch], and
2201 lib/silcutil/unix/silcunixutil.c.
2203 * Changed the -d options in both server and Irssi SILC client
2204 to take the debug string as argument. Affected files
2205 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2207 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Added silc_hash_babbleprint to create a Bubble Babble
2210 Encoded fingerprint. The encoding is developed by Antti
2211 Huima (draft-huima-babble-01.txt), and it creates human
2212 readable strings out of binary data. Affected file
2213 lib/silccrypt/silchash.[ch].
2215 * Print the babble print now in addition of fingerprint as well
2216 in Irssi SILC client. Affected files are
2217 irssi/src/fe-common/silc/module-formats.[ch],
2218 irssi/src/fe-common/silc/core/client_ops.c.
2220 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2222 * Fixed a security problem found in SKE. The initiator's
2223 public key too is now added to the HASH hash value creation
2224 which is signed by the responder to create the SIGN value.
2225 This will prevent anyone in the middle to lie to the responder
2226 about the initiator's public key. If this is done now, the
2227 man in the middle will get caught. Updated the protocol
2230 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2232 * Better installation directory handling. Configure module
2233 paths and other paths automatically to example_silc* files
2234 in doc/. A patch by toma.
2236 * Fixed compiler warning from MPI library, and from SILC RNG.
2239 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2240 It can be configured with ./configure. A patch by toma.
2242 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Find correct make to use in prepare-clean. A patch by
2245 toma. Affected file prepare-clean.
2247 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2249 * Added irssi variables use_auto_addr, auto_bind_ip,
2250 auto_bind_port and auto_public_ip.
2252 * Changed the interface for silc_client_send_key_agreement
2253 in lib/silcclient/silcapi.h
2257 irssi/src/silc/core/silc-core.c
2259 lib/silcclient/silcapi.h
2260 irssi/src/silc/core/silc-channels.c
2261 lib/silcclient/client_keyagr.c
2264 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Added silc_pkcs_public_key_compare to compare two
2267 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2269 * Check that the client who set the founder mode on the
2270 channel is the same client that is giving the founder
2271 mode to itself. It is done by comparing the saved public
2272 key (it is saved even in the authentication is passphrase).
2273 Affected file silcd/command.c.
2275 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Do not process packet for disconnected socket connection.
2278 Affected file lib/silccore/silcpacket.c.
2280 * Process the DISCONNECT packet through scheduler in the
2281 client library. Affected file lib/silcclient/client.c.
2283 * Fixed the silc_client_packet_parse to not to increase
2284 the packet sequence number if the conn->sock and the
2285 current socket connection is not same. This can happen
2286 for example during key agreement when the conn includes
2287 multiple socket connections (listeners). Affected file
2288 lib/silcclient/client.c.
2290 * The sender of the file transfer request now provides also
2291 the pointer (listener) for the key exchange protocol. If
2292 the listener cannot be created then it sends empty key
2293 agreement and lets the receiver provide the listener.
2295 Added `local_ip' and `local_port' arguments to the
2296 silc_client_file_send. If they are provided they are used,
2297 if not then it will attempt to find local IP address, if
2298 not found or bind fails then the remote client will provide
2301 Affected files are lib/silcclient/client_ftp.c and
2302 lib/silcclient/silcapi.h.
2304 * Extended the FILE SEND command to support defining the
2305 local IP and port for key exchange listener. They are
2306 optional. Affected file irssi/src/silc/core/silc-servers.c.
2308 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Defined to WHOIS command reply the sending of fingerprint
2311 of the client's public key (if the proof of posession of the
2312 corresponding private key is verified by the server).
2313 Updated to the protocol specification.
2315 * Added support of receiving the client's public key's
2316 fingerprint in command reply in client library. Affected
2317 file is lib/silcclient/command_reply.c, and
2318 lib/silcclient/idlist.[ch].
2320 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Do not send over 128 chars long nickname to the server
2323 in NICK command. Affected file lib/silcclient/command.c.
2325 * Do not send over 256 chars long channel names to the server
2326 in JOIN command. Affected file lib/silcclient/command.c.
2328 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Assure that silc_server_close_connection cannot be called
2331 twice for same socket context. Affected file is
2334 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Send error message to application if opening file for
2337 writing during file transfer fails. Affected file is
2338 lib/silcclient/client_ftp.c.
2340 Remove all file transfer sessions for a client that we're
2341 removing from ID cache.
2343 Affected file is lib/silcclient/client_ftp.c.
2345 * Fixed silc_net_addr2bin to return correct address. Affected
2346 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2348 * Fixed file transfer session removing on signoff notify.
2349 Affected file irssi/src/silc/core/silc-servers.c.
2351 * Added the SilcClientFileError to be returned in the monitor
2352 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2353 Affected file lib/silcclient/silcapi.h.
2355 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Fixed a crash in silc_client_ftp_free_sessions and
2358 silc_client_ftp_session_free_client. Affected file
2359 lib/silcclient/client_ftp.c.
2361 * Added `disabled' field in the SilcChannelEntry in the server
2362 to indicate if the server entry is disabled. Affected file
2363 silcd/idlist.h, silcd/command[_reply].c.
2365 * SILC server adds now /var/run/silcd.pid everytime it is
2366 started. Affected file silcd/silcd.c.
2368 * Added silc_server_packet_send_clients to send a packet to
2369 the provided table of client entries. Affected file

2372 * Fixed a crash in client resolving in client_prvmsg.c in
2373 client library. Affected file lib/silcclient/client_prvmsg.c.
2375 * Do not actually remove the client directly from ID cache
2376 during SERVER_SIGNOFF, but invalidate it. This way we
2377 preserve the WHOWAS info for the client. Affected file
2378 silcd/server_util.c.
2380 * Fixed SERVER_SIGNOFF notify handling in the server. The
2381 server is now able to process incoming SERVER_SIGNOFF notify
2382 for a server that it doesn't even know about. It will remove
2383 the clients provided in the notify. Affected file
2384 silcd/packet_receive.c.
2386 * Check for partial packet in data queue after every packet that
2387 was found from the queue. Return and wait for more data if
2388 there is partial data in queue. Affected file is
2389 lib/silccore/silcpacket.c.
2391 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Added SilcClietFileError enum to indicate error in
2394 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2395 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2396 Affected files lib/silcclient/silcapi.h and
2397 lib/silcclient/client_ftp.c.
2399 * Check that newsize in silc_buffer_realloc is larger than
2400 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2402 * Added better monitor of file transfers. It now monitors
2403 key agreement protocol during the file transfer too. Added
2404 error reporting too. Affected files
2405 irssi/src/silc/core/silc-servers.c,
2406 irssi/src/fe-common/silc/module-formats.[ch].
2408 * Wrote a help file for FILE command.
2410 * Added silc_rng_global_get_byte_fast to get not-so-secure
2411 random data as fast as possible. Random data is read from
2412 /dev/urandom if available and from the SILC RNG if not
2413 available. It is used in padding generation. Affected file
2414 lib/silccrypt/silcrng.[ch].
2416 * All packets in client library are now processed synchronously.
2417 Optimized packet processing a lot. Affected file
2418 lib/silcclient/client.c.
2420 * All server connection packets are processing synchronously
2421 now in server, to optimize packet processing. Affected file
2424 * Include files are installed now only in Toolkit distribution
2425 if make install is given. Affected files: all Makefile.am's.
2427 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Assure that silc_client_notify_by_server_resolve does not
2430 resolve the client information multiple times. If it cannot
2431 be found by the first it cannot be found at all. Affected
2432 file lib/silcclient/client_notify.c.
2434 * Fixed WHOWAS command reply calling. Affected file
2435 lib/silcclient/command_reply.c.
2437 * Removed all references to silc_idlist_get_client from the
2438 Irssi SILC client since that call is internal call used by
2439 the library. The Irssi SILC client will use now client
2440 retrieval functions found in silcapi.h.
2442 * Fixed a bug in resolving nickname info before sending
2443 private message. It used freed memory. Affected file
2444 irssi/src/silc/core/silc-servers.c.
2446 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Assure my_channels statistics cannot go negative in server.
2449 Affected files silcd/server.c, silcd/server_util.c.
2451 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2455 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Win32 Toolkit changes. Affected files

2459 win32/libsilcclient/libsilc.def,
2460 lib/silcutil/silcutil.c, and
2461 lib/sftp/sftp_fs_memory.c.
2463 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Added silc_net_localip to return local host's IP address.
2466 Affected file lib/silcutil/silcnet.[ch].
2468 * If key exchange or rekey protocol is active for a connection
2469 parse all packets syncronously since there might be packets
2470 in packet queue that we are not able to process without first
2471 processing packets before them. Affected file silcd/server,
2472 lib/silcclient/client.c.
2474 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2475 whether library should continue processing the packet.
2476 Affected file lib/silccore/silcpacket.h.
2478 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2479 SilcSFTPMonitorData to SFTP server to monitor various
2480 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2481 lib/silcsftp/sftp_server.c.
2483 * Added silc_file_size to return file size. Affected file
2484 lib/silcutil/silcutil.[ch].
2486 * Implemented the file transfer support for the client library.
2487 Added preliminary support for simple client to client one-file
2488 transmission. Affected file lib/silcclient/client_ftp.c,
2489 lib/silccilent/client.[ch].
2491 * Added new local command FILE to the Irssi SILC Client.
2492 It is used to perform the file transfer. It has subcommands
2493 SEND, RECEIVE, SHOW and CLOSE. Affected files
2494 irssi/src/silc/core/client_ops.c,
2495 irssi/src/silc/core/silc-server.[ch].

2504 * Renamed silc_file_read and silc_file_write to functions
2505 silc_file_readfile and silc_file_writefile. Added function
2506 silc_file_open and silc_file_close. Affected files
2507 lib/silcutil/silcutil.[ch].
2509 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Resolve the client info when received private message or
2512 channel message for a client which nickname we don't know.
2513 Affected files lib/silcclient/client_prvmsg.c and
2514 lib/silcclient/client_channel.c.
2516 * Do not crash in /KEY if client is not connected. Affected
2517 file irssi/src/silc/core/silc-channels.c.
2519 * Added SilcClientStatus field to the SilcClientEntry in the
2520 lib/silcclient/idlist.h.
2522 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2523 is incomplete and is being resolved, it won't be resolved
2526 Make sure also that USERS command reply does not resolve
2527 twice information. Affected file is
2528 lib/silcclient/command_reply.c.
2530 Make sure that silc_client_get_clients_by_list does not
2531 resolve twice same information.
2533 * Check for valid client->id in the silc_server_free_client_data.
2534 Affected file silcd/server.c.
2536 * Fixed /GETKEY nick@server not to crash if the server entry
2537 is not found. Affected file lib/silcclient/command.c.
2539 * Fixed the silc_server_check_cmode_rights to check the
2540 requested modes correctly. Affected file silcd/command.c.
2542 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Better checks for non-printable chars in nick added.
2545 Affected file silcd/command.c.
2547 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Call the silc_server_udpate_servers_by_server in the
2550 primary router that comes back online in the backup resuming
2551 protocol. Otherwise it routes packets wrong. Affected file
2552 silcd/server_util.[ch], silcd/server_backup.c.
2554 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2557 lib/silcutil/silcbuffmt.[ch].
2559 * Redefined the SILC packet header to include the padding
2560 length. Affected file lib/silccore/silcpacket.[ch].
2562 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2563 length for maximum padding up to 128 bytes). Affected
2564 file lib/silccore/silcpacket.h.
2566 * Removed all backwards support for old 0.5.x MAC thingies.
2567 The SILC packet header change makes it impossible to be
2568 backwards compatible.
2570 * Send the ENDING packet with timeout in the backup resuming
2571 protocol. This is to assure that all routers has connected
2572 to the primary router. Affected file silcd/server_backup.c.
2574 * Changed the RNG to take the first IV from random data. It
2575 used to take it from zero actually. Changed the RNG also
2576 to use /dev/urandom during session. /dev/random is used
2577 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2579 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Changed the SILC packet header to have the first two bytes
2582 (the packet length) encrypted. Affected files aroung the
2583 code tree, lib/silccore/silcpacket.[ch]. Removed the
2584 SilcPacketCheckDecrypt callback. It is not needed anymore
2585 since the silc_packet_receive_process will determine now
2586 whether the packet is normal or special.
2588 * Implemented the unidirectional MAC keys. Affected files
2589 lib/silcske/silcske.c, silcd/protocol.c and
2590 lib/silcclient/protocol.c.
2592 * Implemented the packet sequence number to the MAC computation.
2593 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2594 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2595 lib/silcclient/protocol.c.
2597 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Allow backup router to announce servers. All servers
2600 announced by backup router are added to the global list
2601 automatically. Update hte server's socket to our primary
2602 router also when backup router announces a server.
2603 Affected file silcd/packet_receive.c.
2605 * Do not update the client->router in the function
2606 silc_server_udpate_clients_by_server if the client is on
2607 global list. We might fail to find any specific server
2608 for locally connected clients and local cell clients. They
2609 should still use the `from' and not `to' as client->router.
2610 This fixes backup router resuming protocol. Affected file
2611 silcd/server_util.c.
2613 * Decrease channel statistics count only if the channel
2614 deletion worked. Affected files are silcd/server.c and
2615 silcd/server_util.c.
2617 * Added silc_server_update_servers_by_server to update origin
2618 of all server entries. Used during backup router protocol.
2619 Affected files silcd/server_util.[ch], silcd/server.c. and
2620 silcd/backup_router.c.
2622 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2623 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2624 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2625 lib/silccrypt/silchmac.c.
2627 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Assure that router cannot reroute the same channel message
2630 to the sender. Affected file silcd/packet_receive.c.
2632 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Made better checks that the channel message is not sent
2635 to the router it came from. Affected file is
2636 silcd/packet_send.c. Fixed memory leak too.
2638 * Announce informations for incoming router connection, but
2639 only after checking if it is replaced by backup router.
2640 Affected file silcd/packet_receive.c.
2642 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2644 * Fixed the backup resuming protocol to work in multiple
2645 router environment. Affected file silcd/server_backup.c.
2647 * Route packet only to one router in the function
2648 silc_server_packet_send_to_channel. Affected file is
2649 silcd/packet_send.c.
2651 * Fixed silc_server_send_notify_dest to set the broadcast
2652 flag. Fixed the silc_server_send_notify_topic to actually
2653 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2654 Affected file silcd/packet_send.c.
2656 * Changed the SFTP Filesystem interface. Changed the
2657 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2658 the filesystem operation function. The SilcSFTPFilesystem
2659 is now a context that is allocated by all filesystem allocation
2660 functions and it already includes the operations structure
2661 and filesystem specific context. It is given as argument
2662 now to the silc_sftp_server_start. This made the interface
2663 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2664 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2666 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Changed the backup router adding and getting interfaces
2669 in the server. The router that will be replaced by the
2670 specified backup router is now sent as argument. Affected
2671 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2674 * Added silc_net_addr2bin_ne to return the binary form of
2675 the IP address in network byte order. Affected files
2676 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2678 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Check for existing server ID in silc_server_new_server
2681 and in silc_server_connect_to_router_final and remove the
2682 old entry if it exists. Affected file silcd/packet_receive.c,
2685 * Send the channel message always to only one router, either
2686 in upstream or downstream. Affected file is
2687 silcd/packet_send.c.
2689 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Wrote the definition of the backup resuming protocol to the
2692 protocol specification.
2694 * Removed one redundant channel key generation from normal
2695 server during joining procedure. Removed one redundant
2696 channel key sending from server to router during joining
2697 procedure. Affected file silcd/command.c.
2699 * Made minor bugfixes to the backup router resuming protocol.
2700 Affected file silcd/server_backup.c, server.c.
2702 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Added --disable-asm configuration option. Affected files
2705 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2708 * Implemented the backup resuming protocol that is used to
2709 resume the primary router position in the cell after the
2710 primary router comes back online. Affected files
2711 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2712 and silcd/server_util.[ch].
2714 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Sleep two (2) seconds after sending QUIT command to server.
2717 Affected file lib/silcclient/command.c.
2719 * Assure that if outgoing data buffer is pending do not force
2720 send any data. Affected file silcd/packet_send.c.
2722 * Assure that if outgoing data buffer is pending do not force
2723 send any data. Affected file lib/silcclient/client.c.
2725 * Implemented the backup router support when the primary router
2726 goes down. The servers and routers can now use the backup
2727 router as new primary router without loosing connectivity.
2729 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2732 in the server to indicate disabled entry. All data read
2733 from the connection will be ignored and no data is sent
2734 for entry that is disabled. Affected files are
2735 silcd/idlist.h, silcd/server.c.
2737 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2739 * Created SFTP client and server test programs in the
2740 lib/silcsftp/tests directory.
2742 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2744 * Implemented memory filesystem (virtual filesystem) for
2745 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2748 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2750 * Implemented the SFTP (SSH File Transfer Protocol) to the
2751 lib/silcsftp. It includes SFTP client and SFTP server
2754 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Moved lib/silccore/silcprotocol.[ch] to the
2757 lib/silcutil library.
2759 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2760 take variable argument list pointer as argument. Affected
2761 file lib/silcutil/silcbuffmt.[ch].
2763 * Added silc_buffer_set function that is used to set data
2764 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2765 Affected file lib/silcutil/silcbuffer.h.
2767 * Changed various routines in the core library to use the new
2768 silc_buffer_set instead of allocating new buffer only for
2771 * Added 64-bit value formatting and unformatting support to the
2772 silc_buffer_[un]format routines. Affected file is
2773 lib/silcutil/silcbuffmt.[ch].
2775 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2776 to includes/bitmove.h.
2778 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Fixed channel user mode saving in client library. Affected
2781 file lib/silcclient/command[_reply].c.
2783 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Defined the file transfer to the SILC Protocol. Added
2786 new packet type SILC_PACKET_FTP and defined File Transfer
2787 Payload. The mandatory file transfer protocol is SFTP
2788 (SSH File Transfer Protocol). Affected file in addition
2789 of the internet draft is lib/silccore/silcpacket.h.
2791 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2792 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2793 is used as part of backup router protocol when the primary
2794 router of the cell is back online and wishes to resume
2795 the position as primary router.
2797 * Redefined the MAC generation keys in the protocol. The
2798 same key is not used anymore in both direction. Both
2799 direction will now use different keys for sending and
2800 receiving. This fixes a potential security flaw. This
2801 change causes incompatibilities in the protocol.
2803 * Redefined also the MAC computation from the packet.
2804 An packet sequence number is now added to the MAC
2805 computation. This prevents possible replay attacks against
2806 the protocol. This change too causes incompatibilities
2809 Added `sequence' field to the SilcPacketContext to hold
2810 the current sequence number for the packet.
2812 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Added `created' field to the SilcIDListData in the file
2815 silcd/idlist.h to indicate the time when the entry was
2818 * Added `created' field to the SilcChannelEntry too. Affected
2819 file silcd/idlist.h.
2821 * Added `creation_time' aguments to all the announcement functions
2822 in the server. If it is provided then only the entries that
2823 was created after the provided time frame are actually
2824 announced. Affected file silcd/server.[ch].
2826 * The protocol says that the Channel ID's IP address must be
2827 based on the router's IP address. Added check for this in
2828 the silc_server_new_channel when processing incoming New Channel
2829 Payload. Affected file silcd/packet_receive.c.
2831 * Print out the correct version with --version in SILC client.
2832 Affected file irssi/src/silc/core/silc-core.c.
2834 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Fixed WHOWAS command to check for completnes of the client
2837 entry always, not just when the command is coming from client.
2838 Affected file silcd/command.c.
2840 * Added new function silc_server_packet_queue_purge to purge the
2841 outgoing data queue to the network. After the function returns
2842 it is guaranteed that the outgoing packet queue is empty.
2843 Affected file silcd/packet_send.[ch].
2845 * Purge the outgoing packet queue in the rekey protocol's final
2846 callback to assure that all rekey packets go to the network
2847 before quitting the protocol. Affected file silcd/server.c.
2849 * Added silc_client_packet_queue_parse as similar function as
2850 in server to the client library. The affected file is
2851 lib/silcclient/client.c.
2853 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Splitted silcd/server.c and created silcd/server_util.[ch]
2856 for utility functions.
2858 * Added new socket flag SILC_SF_DISABLED to indicate that the
2859 connection is open but nothing can be sent to or received from
2860 the connection. Affected file lib/silcutil/silsockconn.[ch].
2861 The checking for disabled socket is checked in the low level
2862 silc_socket_write and silc_socket_read functions.
2864 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Allow only nicknames and channel names that fits into the
2867 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2869 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * When processing JOIN command reply in server check that if
2872 the channel exists in our global list we'll move it the local
2873 list. Affected file silcd/command_reply.c.
2875 * Fixed the check whether client is joined on the channel already
2876 in JOIN command. Affected file lib/silcclient/command.c.
2878 * Fixed the JOIN command reply to check whether the channel
2879 already exists. Affected file lib/silcclient/command_reply.c.
2881 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Added silc_ske_status_string to map the SKE error numbers
2884 to readable strings. The affected files are
2885 lib/silcske/silcske[_status].[ch].
2887 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Do not show the private channels on the WHOIS channel list
2890 as it is not allowed by the protocol. The affected file is
2893 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * Assure that the packet length digged from the actual packet
2896 is something sensible in the silc_packet_decrypt_rest_special
2897 in lib/silccrypt/silcpacket.c.
2899 * Free and NULL the allocated pointer in silc_hmac_alloc if
2900 the HMAC allocation fails. The affected file is
2901 lib/silccrypt/silchmac.c.
2903 * Print the selected security properties to the log files in
2904 the server. Affected file silcd/protocol.c.
2906 * Add SKE's reference counter even if calling the completion
2907 callback manually. Otherwise it goes negative, although it
2908 does not cause any problems. The affected file is
2909 lib/silcske/silcske.c.
2911 * Remove the client entry with short timeout after giving the
2912 KILL command. Affected file lib/silcclient/command.c.
2914 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2915 case all found clients are already disconnected (WHOWAS would
2916 found them) in the server. Affected file silcd/command.c.
2918 * Update the last_receive (time of last data received) to be
2919 updated only when received private or channel message so that
2920 the idle time showed in WHOIS makes more sense.
2922 * Added boolean field `valid' in to the SilcClientEntry in the
2923 client library to indicate whether the entry is valid or not.
2924 This fixes the nickname change bug on channel when changing
2925 the nickname to be same than the old (like nick to Nick) the
2926 nickname formatter doesn't set the new nick anymore to Nick@host.
2927 Affected file lib/silcclient/idlist.[ch].
2929 * Now actually fixed the nickname changing on disconnection.
2930 Added new function silc_change_nick to the Irssi SILC Client.
2931 Affected file irssi/src/silc/core/client_ops.c,
2932 irssi/src/silc/core/silc-nicklist.[ch].
2934 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2936 * Check that the public key exists in the GETKEY command before
2937 trying to encode it. Affected file silcd/command.c.
2939 * Print some notifications on received public keys with GETKEY
2940 command in the Irssi SILC Client. Affected files are
2941 irssi/src/fe-common/silc/module-formats.[ch],
2942 irssi/src/silc/core/client_ops.c.
2944 * Use IDENTIFY command to resolve the server information in the
2945 GETKEY command instead of INFO command. Affected file
2946 lib/silcclient/command.c.
2948 * All command reply functions in the client library now calls
2949 the pending command reply callbacks even if an error has
2950 occurred. The server has done this a long time and now it was
2951 time to move the client library to this as well. Now all
2952 errors can be delivered back to the pending command reply
2953 callbacks if necessary. Affected files are
2954 lib/silcclient/command[_reply].[ch].
2956 * Change the nickname on disconnection back to the username
2957 because in reconnect the server will enforce it to it anyway.
2958 Affected file irssi/src/silc/core/silc-servers.c.
2960 * Fixed a config file parsing bug in the Irssi SILC client.
2961 Affected file irssi/src/silc/core/clientconfig.c.
2963 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * When printing the channel mode on JOIN, verify that the
2966 channel key and channel's HMAC are valid. Affected file
2967 irssi/src/silc/core/client_ops.c.
2969 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2972 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2973 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2975 * Removed channel key rekey task deleting from the function
2976 silc_server_save_channel_key. Affected file silcd/server.c.
2977 Added explicit timeout task context instead that is used to
2978 delete the task if we are registering a new task before the
2979 new task has elapsed.
2981 * When channel key rekey occurs the client library now saves
2982 the old channel key for a short period of time (10 seconds) and
2983 is able to use it in case some is still sending channel
2984 messages encrypted with the old key after the rekey. Affected
2985 file lib/silcclient/[idlist.h|client_channel.c].
2987 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Added check to the silc_server_new_id_real to not accept
2990 new ID if it is the sender's own ID. Affected file is
2991 silcd/packet_receive.c.
2993 * Assure that we do not announce ourself or the one we've
2994 sending our announcements when we're router and are announcing
2995 servers to our primary router. Affected file silcd/server.c.
2997 * Fixed silc_server_command_identify_check_client to assemble
2998 correct WHOIS packet. It send corrupted WHOIS packet and
2999 caused problem with router to router connections. Affected
3000 file silcd/command.c.
3002 Fixed also silc_server_command_whois_check the same way
3003 as for the IDENTIFY command.
3005 * Added new SilcIDListStatus to the server in the SilcIDListData
3006 structure. The status now includes the current status of
3007 the entry (like registered, resolved etc.). Affected file
3008 silcd/idlist.[ch]. Defined a bunch of different status types
3009 as well. This replaced the old boolean registered field as well.
3011 Added resolve_cmd_ident field to the SilcClientEntry structure
3012 too so that if the entry is for example being resolved so
3013 another command may attach to the same pending command reply
3014 without requiring to resolve the same entry again. This concept
3015 should optimize the WHOIS and the IDENTIFY resolving under
3016 heavy load by taking away unnecessary resolving for entries
3017 that are being resolved already.
3019 Added support for adding multiple pending commands for one
3020 command idenfier. Affected file silcd/command[_reply].[ch].
3022 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3023 before deleting the data. Otherwise the hash table will have
3024 freed data in comparison functions. Affected file is
3025 silcd/command_reply.c.
3027 * Fixed silc_idlist_replace_client_id to add the new entry to
3028 the cache with NULL nickname. Otherwise there will be invalid
3029 memory as the nickname after the nickname is freed. Affected
3030 file silcd/packet_receive.c.
3032 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3033 saved into wrong slots because the previous number of entries
3034 was not taken into account. Affected file silcd/idlist.c.
3035 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3037 * If we are router and we receive JOIN notify to a channel that
3038 does not have any users then notified client is marked as the
3039 channel founder, as it is it. The affected file is
3040 silcd/packet_receive.c
3042 * Added to the extended hash table API's table_del_*ext functions
3043 the destructor as argument too, so that the caller can decide
3044 which destructor to use or whether to use destructor at all.
3045 Affected file lib/silcutil/silchashtable.[ch].
3047 * Fixed ID Cache purging. It actually deleted the entries from
3048 the hash table after the data was freed. The hash table ended
3049 up comparing freed memory. The affected file is
3050 lib/silccore/silcidcache.c.
3052 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3054 * Fixed Irssi SILC client's KILL command's HELP syntax.
3056 * The USERS command now resolves the detailed user information
3057 if the userinfo field is missing. Affected file is
3058 lib/silcclient/command_reply.c.
3060 * Do not print error in silc_file_read if the read file does
3061 not exist. Just silently return NULL. Affected file is
3062 lib/silcutil/silcutil.c.
3064 * Fixed the silc_log_output to not wine about NULL filename
3065 and to not create some bogus " " filename. Affected file is
3066 lib/silcutil/silclog.c.
3068 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Fixed various printing bugs on the user interface in the
3071 Irssi SILC Client. Minor changes that were forgotten from
3074 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3076 * Fixed the configure.in.pre and the compilation and distribution
3077 environment to support the new autoconf 2.52. That version is
3078 now required to compile the CVS trunk.
3080 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3082 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3083 to generally parse user@fqdn format strings. Affected file
3084 lib/silcutil/silcutil.c.
3086 * Added nickname_format and nickname_force_format fields to the
3087 SilcClientParams structure. The first one defines the format
3088 for the nicknames that the library will enforce if the receives
3089 multiple same nicknames. The second one is boolean value and
3090 can be used to force the library to always enforce the format
3091 to the nicknames regardles whether there are multiple nicknames
3092 or not. This configurable formatting was employed to flexibly
3093 support accessing multiple nicknames from the user interface.
3094 The userinterface can now set the nicknames to what ever format
3095 they prefer. Affected file lib/silcclient/silcapi.h.
3097 Added function silc_client_nickname_format to the file
3098 lib/silcclient/idlist.c. It performs the nickname formatting.
3100 Added new field `hostname´ to the SilcClientEntry context.
3101 It holds the hostname of the client. Affected file is
3102 lib/silcclient/idlist.h.
3104 * Irssi SILC Client sets the nicknames in nick@hostn format.
3105 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3106 irssi/src/silc/core/silc-core.c.
3108 The WHOIS printing now also shows both the real nickname and
3109 the formatted nickname so that user knows how to access the
3110 user if there are multiple same nicknames cached. Affected
3111 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3112 printing formatting too to take the hostname now as a separate
3113 argument. The Affected file is
3114 irssi/src/fe-common/silc/modules-formats.[ch].
3116 * Changed the silc_client_get_clients_local to accept the formatted
3117 nickname as argument. It accepts the real nickname too but the
3118 formatted nickname can be used to find the true entry from
3119 multiple entries. Affected file lib/silcclient/silcapi.h and
3120 lib/silcclient/idlist.c.
3122 * Added nickname_format_parse field to the SilcClientParams.
3123 It is a callback function provided by the application to parse
3124 the nickname out of the formatted nickname string. The library
3125 calls it to get the nickname from the formatted string. Since
3126 the application generally knows better the format of the nickname
3127 string it parses it instead of the library, even though library
3128 encodes the formatted string. If the callback function is not
3129 provided then the library will use the string as is. The
3130 affected file is lib/silcclient/silcapi.h.
3132 * All the nickname strings passed to the client library in
3133 commands are now expected to be formatted nickname strings.
3134 If the command does not support the formatted nickname string
3135 it will assume that the sent string is the actual nickname.
3136 Affected file lib/silcclient/command.c.
3138 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Added public key authentication support to OPER and SILCOPER
3141 commands in the client library. Affected file is
3142 lib/silcclient/command.c.
3144 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3146 * Changed the get_auth_methdod client operation to be asynchronous.
3147 It can be async if the application resolves the authentication
3148 method from the server during the negotiation. Added new
3149 SilcGetAuthMeth completion callback that the application will
3150 call after resolving the authentication method.
3152 Added function silc_client_request_authentication_method that
3153 the application can use to resolve the authentication method
3154 from the server. Added also SilcConnectionAuthRequest callback
3155 that the library will call after the server has replied. The
3156 application can call this function if it does not know the
3157 current authentication method.
3159 Affected files are lib/silcclient/client.c and
3160 lib/silcclient/silcapi.h.
3162 * The Irssi SILC client now automatically resolves the authentication
3163 method incase any configuration information is not present (and
3164 currently there never is). The affected file is
3165 irssi/src/silc/core/client_ops.c.
3167 * Fixed public key authentication from the client library.
3168 Affected file lib/silcclient/protocol.c. Changed also the
3169 protocol specification about the public key authentication in
3170 the connection authentication protocol. The actual data to be
3171 signed is now computed with a hash function before signing.
3173 * Fixed the public key authentication from the server as well.
3174 Affected file silcd/protocol.c.
3176 * Removed the mlock()'s from the memory allocation routines.
3177 Affected file lib/silcutil/silcmemory.c. The ./configure does
3178 not check anymore for the mlock(). Affected file is
3181 * Fixed USERS command in server to allow the execution of the
3182 command for private and secret channels if the client sending
3183 the command is on the channel. Affected file silcd/command.c.
3185 * Fixed silc_client_get_clients_local to return the clients
3186 count correctly. It could return wrong value. Affected file
3187 lib/silcclient/idlist.c.
3189 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3192 types. The assembler optimizations seemed not to like 64-bit
3193 data types. The assmebler optimizations thus are now enabled
3194 also for BSD systems as opposed to only enable them for Linux.
3196 * Do not check for threads at all on BSD systems. Affected
3197 file configure.in.pre.
3199 * Removed -n and -h options from the Irssi SILC Client since
3200 they are not used in silc.
3202 * Fixed the prime generation to assure that the first digit
3203 of the generated random number is not zero since our conversion
3204 routines does not like number strings that starts with zero
3205 digit. If zero digit is seen the random number is regenerated.
3206 This caused some corrupted RSA keys when the zero first digit
3207 was met. Affected file lib/silcmath/silcprimegen.c.
3209 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3211 * Fixed WIN32 configuration in the ./configure script.
3212 Fixed to include xti.h on environments that has it.
3213 Patches by Carsten Ilchmann and andrew.
3215 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Changed the silc_id_create_client_id to be collision
3218 resistant. It is now assured that there cannot be created
3219 two same client ID's. I suspect that some weird bugs in
3220 the server were actually caused by duplicate Client IDs.
3221 Affected file silcd/serverid.[ch]. A router receiving
3222 new ID now also assures and informs the sending server
3223 if the ID caused collision.
3225 * Changed the silc_id_create_channel_id to also assure that
3226 there are no collisions.
3228 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3230 * Statement about ignoring the Mutual Authentication flag when
3231 performing rekey with PFS was a bit misleading. It is ignored
3232 if it was set in the initial negotiation, it cannot be even
3233 set in the rekey. Fixed in the ke-auth draft. Started the
3234 new versions of the protocol drafts in the doc/.
3236 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Fixed a bug in silc_client_command_identify_save when saving
3239 new channel information. The channel name was no duplicated
3240 and caused crash on exit. Affected file is
3241 lib/silcclient/command_reply.c.
3243 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Fixed the getkey command handling in the server. Send just
3246 empty OK reply to the sender if the key could not be fetched
3247 (but everything else was ok, like the key just was not available).
3248 Changed the public key parameter to optional in the protocol
3249 specs so that empty OK reply can be sent. Affected file
3252 Added a message to Irssi SILC client to tell to user if the
3253 server did not return a public key.
3255 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3257 * Fixed a channel key regeneration bug. It registered new
3258 timeout tasks exponentially until all system resources were
3259 used. Affected file silcd/server.c.
3261 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3263 * Added the SILC Document generator to the scripts/silcdoc.
3264 It can be used to generate the Toolkit Reference Manual out
3265 of the source tree. Internally it will also use the RoboDoc
3266 generator now imported in util/robodoc.
3268 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Added couple of return's in rekey protocol if error orccurred
3271 during the protocol. The execution must be terminated.
3272 Affected file silcd/protocol.c. Also, terminate the protocol
3273 always with timeout.
3275 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * The client's Client ID was created initally from the wrong
3278 nickname (it could have been in format nick@host) in the
3279 silc_server_new_client. Affected file silcd/packet_receive.c
3281 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3283 * Added some SILC_LOG_ERROR's to various error conditions
3284 if client could not be added to ID cache. Affected files
3285 silcd/packet_receive.c and silcd/server.c.
3287 * When client's sock->user_data is freed, NULL also the
3288 client->router and client->connection pointers. Added check
3289 for these pointers being NULL to various places around the
3290 code. Affected file silcd/server.c.
3292 * Added client->data.registered == TRUE checks to various
3293 places around the code to assure that unregistered client's
3294 are not handled when it is not allowed. Affected file
3297 * Added `bool registered' fields to all
3298 silc_idlist_[server|client]_get_* routines to indicate whether
3299 the fetched client needs to be registered or not. Affected
3300 file silcd/idlist.[ch].
3302 * Add your own entry as registered to the ID cache in the
3303 server. Affected file server.c.
3305 * Fixed a bug in silc_server_new_server. The SilcServer was
3306 set as the new server's context instead of SilcServerEntry.
3307 This naturally caused some weird bugs.
3309 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Do not delete the channel rekey task when adding it
3312 for in silc_server_create_channel_key.
3314 * Changed the silc_server_create_channel_key to return
3315 TRUE or FALSE to indicate the success of the channel key
3318 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Fixed MSVC++ project files and added missing files to
3321 Makefiles under win32/.
3323 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Do not add TCP_NODELAY flag if the operating system
3326 does not have it defined. Affected files are
3327 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3329 * Fixed buffer overflow from Irssi SILC Client. Affected
3330 file irssi/src/fe-common/core/themes.c.
3332 * Fixed double free in client library in the file
3333 lib/silcclient/client.c when disconnecting from server.
3335 * Applied double free patch from cras to Irssi SILC client.
3336 Affected files irssi/src/core/[modules/expandos].c
3338 * Fixed the disconnection handling to Irssi SILC Client.
3339 The application must call silc_client_close_connection
3340 in ops->connect client operation in case of failure of
3341 the connection. Affected file is
3342 irssi/src/silc/core/client_ops.c.
3344 * Do not set sock->protocol to NULL in the function
3345 silc_client_close_connection after executing the protocol's
3346 final callback since the sock might not be valid anymore.
3347 Affected file lib/silcclient/client.c.
3349 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Do not enable SILC_THREADS if the linking with libpthread
3352 did not happen. Affected file configure.in.pre.
3354 * Added notion to protocol specification that server must
3355 verify the sent authentication payload with CMODE when
3356 setting the channel founder key. Implemented it to the
3357 server. Affected file silcd/command.c.
3359 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Added _EXTRA_DIST SILC distribution variable to the
3362 distributions file. It is used to conditionally add extra
3363 files or directories to the specific distribution. Affected
3364 files ./prepare, Makefile.am.pre and distributions.
3366 Removed the `_' from the start of the distribution names.
3369 * Added README.WIN32 for instructions to compile the Toolkit
3372 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Fixed a double free in disconnection in the server. Affected
3375 file is silcd/server.c.
3377 * Fixed the lib/silcske/groups.c to work now also with GMP
3378 MP library. The string conversion did not work when using
3379 specific base and the base is indicated in the string as well.
3381 * Created win32/ directory which now includes MSVC++ specific
3382 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3383 It will appear only in the toolkit distribution
3385 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Changed the key material distribution function in case when
3388 the hash output is too short. The data is now concatenated
3389 a bit differently than it used to. Made the change to the
3390 SKE protocol specification.
3392 * Added better GMP detection to configure.in.pre. A patch
3395 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3397 * Fixed a minor bug in SKE that might cause some problem on
3398 some platforms. Affected file lib/silcske/silcske.c.
3400 * Added the cookie checking for initiator in the SKE. It checks
3401 that the responder returns the sent cookie unmodified. The
3402 affected file is lib/silcske/silcske.c. Added new SKE
3403 error type INVALID_COOKIE that can be sent during the
3404 negotiation. Fixed some memory leaks as well.
3406 * Added the "invalid cookie" error message to Irssi SILC client's
3409 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Added `task_max' field to the SilcClientParams to indicate
3412 the maximum tasks the scheduler can handle. If set to zero,
3413 default values are used. Affected file lib/silcclient/silcapi.h.
3415 * Fixed memory leaks in silc_client_close_connection. Affected
3416 file lib/silcclient/client.c.
3418 * Added silc_client_del_client_entry to client library to free
3419 all memory of given client entry. Affected file is
3420 lib/silcclient/idlist.[ch].
3422 * Added new functions silc_client_del_channel and
3423 silc_client_del_server to delete channel and server entries.
3424 Affected file lib/silcclient/[silcapi.h/idlist.c].
3426 * Removed silc_client_del_client_by_id from silcapi.h.
3428 * Fixed the INFO command to return the server's own info
3429 correctly when querying by Server ID. Affected file is
3432 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Removed the non-blocking settings in WIN32 code in the
3435 silc_sock_[read/write] and added SleepEx instead. Affected
3436 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3437 of input data is now checked with FIONREAD and ioctlsocket.
3439 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Call silc_schedule_task_del_by_context in the
3442 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3443 Affected file lib/silccore/silcprotocol.c.
3445 * Call silc_protocol_cancel for active protocols in the
3446 silc_server_close_connection if the funtion
3447 silc_server_free_sock_user_data has not been called.
3448 Affected file silcd/server.c.
3450 * Generic tasks cannot be deleted using the del_by_fd
3451 task deleting function since generic tasks does not match
3452 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3454 * Added a notion to SILCOPER help file that the SILCOPER works
3455 only on router server, not on normal server.
3457 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Added for WIN32 support for the new scheduler as well.
3460 Affected file lib/silcutil/win32/silcwin32schedule.c.
3462 * Fixed the SHA1 implementation to work on various platforms.
3464 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3467 API. It is part of the scheduler now. Everything else is
3468 as previously but some functions has changed their names.
3469 Checkout the lib/silcutil/silcschedule.h for the interface.
3470 Updated all applications to use the new interface. Affected
3471 files are lib/silcutil/silcschedule.[ch].
3473 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Found a bug in the SKE implementation. The HASH value,
3476 specified by the protocol, was not computed correctly. The
3477 public key of the responder was not added to the computation
3478 even though it is mandatory. Affected file lib/silcske/silcske.c.
3479 This unfortunately causes incompatibilities with older
3480 clients and servers.
3482 * Added WIN32 specific network init and uninit functions:
3483 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3484 the Winsock2. Affected file lib/silcutil/silcnet.h and
3485 lib/silcutil/win32/silcwin32net.c.
3487 * Set the socket always to nonblocking mode on WIN32 after
3488 reading data or writing data. Affected file is
3489 lib/silcutil/win32/silcwin32sockconn.c.
3491 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Fixed various compilation problems under WIN32. Affected
3494 files lib/silcutil/win32/silcwin32thread.c and
3495 lib/silcutil/win32/silcwin32schedule.c.
3497 * Removed all _internal.h #includes from public header
3498 files. Internal headers must never be included from
3501 Removed also the lib/silcske/payload_internal.h file.
3503 * All include files that may be needed (public and some others
3504 included by the public headers) by application developers are
3505 now copied to the ./includes directory. It does not copy any
3506 internal headers. Affected file Makefile.defines.pre and all
3507 Makefile.am's under lib/ and subdirs.
3509 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3511 * Do not change the ~/.silc directory's permissions automatically.
3512 Affected file irssi/src/silc/core/clientutil.c.
3514 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Do not cancel the protocol in silc_server_close_connection
3517 it might cause recursion. Now cancelled in the function
3518 silc_server_free_sock_user_data. Affected file silcd/server.c.
3520 * Fixed the silc_server_remove_clients_by_server to regenerate
3521 the channel keys correctly finally. Added also new function
3522 silc_server_remove_clients_channels to actually do it.
3523 Affected file silcd/server.c.
3525 * Fixed the silc_server_new_channel to not crash by giving
3526 wrong router to the new channel. Affected file is
3527 silcd/packet_receive.c.
3529 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3532 which is given as argument to the silc_client_alloc now.
3533 It can be used to configure the client and set various parameters
3534 that affect the function of the client.
3536 * The USERS command in server did not check whether the channel
3537 is private or secret. Affected file silcd/command.c.
3539 * Added new argument to the USERS command in protocol specification.
3540 The USERS command now can take the channel name as argument
3541 as well. Added support for this in client and server and
3542 updated the protocol specs.
3544 * Completed the GETKEY command in client. It can be now used
3545 to fetch also servers public key not only some clients.
3546 Affected files lib/silcclient/command[_reply].c.
3548 * Added silc_client_get_server to return server entry by the
3549 server name. Affected files lib/silcclient/silcapi.h and
3552 * Redefined the IDENTIFY command in protocol specification to be
3553 more generic. It now can be used to query information about
3554 any entity in the SILC Network, including clients, servers and
3555 channels. The query may be based either the entity's name
3556 or the ID. Added support for this in both client and server.
3558 Affected files silcd/command.c and lib/silcclient/command.c
3559 and command_reply.c.
3561 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3562 the _from_client and _from_server functions. Affected file
3565 * Added silc_client_get_channel_by_id_resolve to the file
3566 lib/silcclient/silcapi.h to resolve channel information by
3567 its ID. Added also silc_client_get_channel_by_id that
3568 does not resolve it from the server.
3570 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Added SilcServerEntry context into the client library
3573 to represent one server. The INFO command now allocates
3574 these to save the resolved server info. For now on the
3575 client library will also keep information about servers,
3576 connected and resolved with INFO.
3578 The INFO command now allocates the SilcServerEntry context
3579 and saves the server info there. The COMMAND_REPLY in
3580 the INFO now returns the parameters to application in
3581 same order as defined in the protocol specification.
3583 The entries are cached in the client->server_cache.
3585 * The INFO command is now issued after received the Client ID
3586 from the server. Affected file lib/silcclient/client.c.
3588 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3589 to the application as the mode changer might be server.
3590 It is guaranteed that NULL is not returned anymore to the
3591 application. Affected file lib/silcclient/client_notify.c.
3593 The ID Type is now also passed to the application so that
3594 it can check whether the returned entry is SilcClientEntry
3597 Added new function silc_client_get_server_by_id to return
3598 the server entry by ID. Affected files are the
3599 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3601 * Do not create the channel in the Irssi SILC Client when issuing
3602 the JOIN command but when received the sucessful JOIN command
3603 reply. Otherwise the channel might get created even though we
3604 could not join it. The Affected file is
3605 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3607 * Fixed a channel joining bug in router. The router must also
3608 check the channel modes, invite and ban lists etc. when serving
3609 the JOIN command sent by normal server. Affected file is
3610 silcd/command.c. The router now resolves the client's
3611 information from the server who sent the JOIN command if it
3612 does not know it, and processes the JOIN command only after
3615 * Changed the SilcCommandCb to take new argument; void *context2.
3616 Affected file lib/silccore/silccommand.h
3618 The second argument in the command callbacks in the server now
3619 includes the SilcServerCommandReplyContext if the command was
3620 called as pending command callback from the command reply.
3621 Otherwise it is NULL. When called as pending the status of the
3622 command reply will be checked and if it was erronous the
3623 error will be sent to the original sender of the command.
3624 This way the client always receives the error messages even
3625 though the server was actually the one who received the error
3626 when it resent the command to router, for example. Affected
3627 files silcd/command[_reply].[ch].
3629 * Fixed sending WHOWAS command's error message to client if
3630 the requested client could not be found. It was missing.
3633 * Changed the CMODE and CUMODE commands reply arguments in the
3634 protocol specification. The Channel ID is now sent in both
3635 of the commands to identify the channel. Implemented this
3636 new feature to the client and server. Affected files
3637 lib/silcclient/command_reply.c and silcd/command.c.
3639 * Made better checks for invite and ban lists in the JOIN
3640 command in server. Affected file silcd/command.c.
3642 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3644 * The server now performs the incoming host IP/DNS lookup
3645 using the silc_socket_host_lookup and thus does not block
3646 the server anymore. Affected file silcd/server.c.
3648 * Completed the multi-thread support for SILC Scheduler in
3649 the lib/silcutil/silcschedule.c.
3651 * Fixed the configure.in.pre to detect the pthread correctly
3654 * Fixed a deadlock in silc_task_queue_wakeup in the file
3655 lib/silcutil/silctask.c.
3657 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Added new function silc_schedule_wakeup that is used in
3660 multi-threaded environment to wakeup the main thread's
3661 schduler. It needs to be used when a thread adds a new task
3662 or removes a task from task queues. After waking up, the
3663 scheduler will detect the task queue changes. If threads
3664 support is not compiled in this function has no effect.
3665 Implemented the wakeup mechanism to both Unix and WIN32
3666 systems. Affected files are lib/silcutil/silcschedule.[ch],
3667 lib/silcutil/unix/silcunixschedule.c and the
3668 lib/silcutil/win32/silcwin32schedule.c.
3670 * Added new function silc_task_queue_wakeup to wakeup the
3671 scheduler by the specified task queue. Affected file
3672 lib/silcutil/silctask.[ch].
3674 * The silc_socket_host_lookup_start now wakes up the scheduler
3675 after adding the timeout task. Affected file is
3676 lib/silcutil/silcsockconn.c.
3678 * The silc_socket_host_lookup is synchronous now if the threads
3679 support is not compiled in. However, the callback is still
3680 called asyncronously through the scheduler, anyway. Affected
3681 file lib/silcutil/silcsockconn.c.
3683 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3685 * Added new function silc_socket_host_lookup to perform
3686 asynchronous IP and FQDN lookups for the socket connection.
3687 Affected files lib/silcutil/silcsockconn.[ch].
3689 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3692 that may or may not compile the mutex support in.
3694 Changed the silc_mutex_alloc interface. It allocates the
3695 mutex now to the sent pointer and returns TRUE or FALSE.
3697 Affected file lib/silcutil/silcmutex.h.
3699 * Wrote the SILC Task Queue interface to support multi-threads.
3700 Affected file lib/silcutil/silctask.[ch].
3702 * Wrote the SILC Scheduler to support multi-threads. Affected
3703 file lib/silcutil/silcschedule.c.
3705 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3708 in lib/silcutil/win32/.
3710 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Defined SILC Mutex API and SILC Thread API and implemented
3713 them for Unix. Affected files are
3714 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3715 lib/silcutil/unix/silcunixmutex.c and
3716 lib/silcutil/unix/silcunixthread.c.
3718 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Fixed the silc_server_remove_clients_by_server's channel
3721 key re-generation. The hash table handling was incorrect
3722 and would not work with many channels. Affected file is
3725 * Fixed some memory leaks around the server code.
3727 * Rewrote the silc_server_get_users_on_channel to support IPv6
3728 based Client ID's. Affected file silcd/server.c.
3730 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3731 specification. However, a separate document must be written
3732 to define the detailed signing procedure and the payload
3733 associated with the flag. Defined the flag to the
3734 lib/silccore/silcchannel.h as well.
3736 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3738 * Changed the dynamic tables to static size tables in the
3739 lib/silccrypt/silchmac.c.
3741 * Removed GCC dependencies from the code. A patch by cras.
3743 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Do not show the error "Error receiving packet bla bla"
3746 in server if it really was not an error (-2 means that reading
3747 is pending). Affected file silcd/server.c.
3749 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3751 * Fixed a possible crash in silc_server_remove_clients_by_server
3752 in silcd/server.c. Fixed there also some memory leaks.
3754 * Fixed the silc_idlist_replace_client_id. It could replace
3755 wrong key in the hash table. Affected file silcd/idlist.c.
3757 * Do not check whether there are global users on the channel
3758 if the channel->global_users is FALSE. Affected functions
3759 silc_server_remove_from_one_channel and
3760 silc_server_remove_from_channels in silcd/server.c. Also,
3761 do not check if the removed client is local as we can be
3762 sure that global client was not removed from the channel
3763 and checking for global users is not needed.
3765 * The silc_server_remove_clients_by_server now re-generates
3766 the channel keys correctly for those channels that had
3767 clients removed from them. Affected file silcd/server.c.
3769 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Found the reason of random crashes in the server. We weren't
3772 ignoring the SIGPIPE signal (which can be sent in write())
3773 and it crashed the server. Affected file silcd/silcd.c.
3775 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Assure that sock->user_data is not NULL in the function
3778 silc_server_packet_send in silcd/packet_send.c.
3780 * Disconnect the remote connection if it could not be added
3781 to any ID lists in the server. The affected file is
3784 * Check in silc_server_packet_send[_real/dest] that the
3785 socket is not disconnecting and ignore the data if it is.
3786 Affected file silcd/packet_send.c.
3788 * Define inline to __inline on native WIN32 compilation.
3789 Affected file includes/silcwin32.h.
3791 * Added some explicit type casts for inline code since MSVC
3792 require them. Affected files lib/silcutil/silcbuffer.h,
3793 lib/trq/silcdlist.h and lib/trq/silclist.h.
3795 * Print warning in log files from now on if the packet
3796 decryption fails. Affected file silcd/server.c.
3798 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * Changed the `say' client operation's interface to accept
3801 new `type' argument to indicate the type of the message sent
3802 by the library. The application may filter the library's
3803 messages according the type. The affected file is the
3804 lib/silcclient/silcapi.h.
3806 * Added two new functions to lib/silcclient/silcapi.h:
3807 silc_client_del_client and silc_client_del_client_by_id.
3808 Affected file lib/silcclient/idlist.c.
3810 * Moved the clientincludes.h from includes/ to silc/ and
3811 serverincludes.h from includes/ to silcd/.
3813 * The modes for the CMODE and CUMODE are now passed as
3814 uint32 for application with COMMAND_REPLY. The affected
3815 file is lib/silcclient/command_reply.c.
3817 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3819 * /WHOIS without arguments shows client's own information.
3820 Affected file lib/silcclient/command.c.
3822 * Changed PING to not accept any arguments. The specs
3823 says that client can ping only the connected server so
3824 requiring an argument is not needed. Affected file is
3825 lib/silcclient/command.c.
3827 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3829 * Fixed a fatal bug in private message sending and reception
3830 encryption and decryption when using private message keys.
3831 The implementation was incorrect and did not follow the
3832 specification. It causd that some of the message were
3833 lost since it did not use the sending and receiving keys
3834 as the protocol suggests. This has been fixed and will cause
3835 incompatibilities with older clients when sending private
3836 message encrypted with private message keys. Affected files
3837 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3838 and various other in Irssi SILC Client.
3840 Added `responder' boolean argument to the functions
3841 silc_client_add_private_message_key[_ske] to indicate when
3842 the key is added as responder or initiator of the key
3845 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3847 * Removed the silc_ske_check_version function and created
3848 a SilcSKECheckVersion callback. Added also a function
3849 silc_ske_set_callbacks that is now used to set all SKE
3850 callbacks. The callback functions are not given to
3851 the SKE functions anymore, but this function is used to
3854 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3856 * Added `silc_version' argument to the silc_client_alloc
3857 to define the version of the application for the library.
3858 The library will use the version string to compare it
3859 against the remote host's (usually a server) version
3860 string. Affected file lib/silcclient/silcapi.h
3862 * Added the KE protocol context to Key Agreement context
3863 in client library so that we can abort the SKE if it
3864 is in process when we get timeout. Affected file is
3865 lib/silcclient/client_keyagr.c.
3867 * Do not resolve the client ID forever if it returns in the
3868 first time that such client does not exist. This was done
3869 for example with private message. Affected file is
3870 lib/silcclient/client_prvmsg.c.
3872 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Do not add regex.h for WIN32. The affected file
3875 includes/silcincludes.h.
3877 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3878 not work yet 100%. It generates the DLL's automatically
3879 when compiling with --with-win32 under cygwin.
3881 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3883 * lib/contrib/regex.c is not compiled on WIN32.
3885 * Added silc_net_get_socket_opt function to the
3886 lib/silcutil/silcnet.h.
3888 * Added includes/silcwin32.h for WIN32 specific includes
3891 * Do not use ptime structure or any of the posix process
3892 functions on WIN32 in lib/silccrypt/silrng.c.
3894 * Added silc_gettimeofday to provide generic function
3895 for struct timeval on all platforms. Added the function
3896 to lib/silcutil/silcutil.h.
3898 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3901 library as they clearly belong there. As a plus side we
3902 can make the actual socket connection routines platform
3905 Added also new generic function silc_socket_read and
3906 silc_socket_write (that used to be silc_packet_[read/write].
3907 The implementation of these are platform specific.
3909 * Added WIN32 specific routines of silc_socket_[read/write]
3910 to lib/silcutil/win32/silcwin32sockconn.c.
3912 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * Added preliminary support for native WIN32 compilation under
3915 cygwin (using the -mno-cygwin option for GCC) to the
3916 ./configure.in.pre. The --with-win32 now prepares the
3917 compilation for native WIN32.
3919 * Rewrote the SILC Scheduler interface in the file
3920 lib/silcutil/silcschedule.h. The scheduler is now context
3921 based and does not have anymore any global static scheduler.
3922 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3923 and created lib/silcutil/win32 directory for WIN32 based
3926 * Added Unix specific network routines to the
3927 lib/silcutil/unix/silcunixnet.c and the old
3928 lib/silcutil/silcnet.c includes now only generic routines.
3930 Added WIN32 specific network routines to the
3931 lib/silcutil/win32/silcwin32net.c.
3933 * Added Unix specific utility functions from the
3934 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3936 * Added WIN32 SILC Scheduler to the file
3937 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3940 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3942 * Do not handle JOIN notify in the server if the target client
3943 is not registered (idata->registered == FALSE). The affected
3944 file is silcd/packet_receive.c.
3946 * Update the nickrec->founder in event_cumode in the Irssi SILC
3947 client. Affected file irssi/src/silc/core/silc-channels.c.
3949 * Fixed the CUMODE_CHANGE notify handling in the server when
3950 server and router are announcing their clients on channels.
3951 Now the mode changes are saved and notified correctly. The
3952 affected file is /silcd/packet_receive.c.
3954 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3955 They really did not replace the cache entry in the ID Cache.
3956 Now they do that. Affected file silcd/idlist.c.
3958 * Fixed the KICK notify handling in the Irssi SILC client to
3959 update the channel records so that the kicked client does not
3960 appear to be on the channel. The affected file is
3961 irssi/src/silc/core/silc-channels.c.
3963 * Always update the conn->current_channel when executing command
3964 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3966 * Fixed the KILL notify handling in Irssi SILC client to remove
3967 the killed client on all channels.
3969 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Fixed the silc_parse_command_line to remove extra spaces
3972 from the start and end of the arguments. Affected file is
3973 lib/silcutil/silcutil.c.
3975 * Cancel and free any active protocol in the function
3976 silc_server_close_connection. Affected file silcd/server.c.
3978 * Cancel and free any active protocol in the function
3979 silc_client_close_connction. Affected file is
3980 lib/silcclient/client.c.
3982 * Do not execute the KILL command for clients that are in
3983 history (ie. they are not in the network). Affected file is
3986 * Fixed KILL notify handling, client does not crash anymore.
3987 Affected file irssi/src/silc/core/silc-channels.c.
3989 * Reduced the default packet buffer size from 2048 to 1024 in
3990 lib/silccore/silcpacket.c.
3992 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3993 counter to the SKE context that is incresed when the SKE library
3994 performs async operation outside the library. If the outside
3995 process frees the SKE context and FREED status will be set
3996 and the library will detect after the sync operation that the
3997 libary is freed. The affected files are
3998 lib/silcske/silcske[_status].[ch].
4000 * Resolve the client entry information in the function
4001 silc_client_channel_message to assure that NULL pointer is not
4002 passed as client entry to the application. */
4004 * Fixed the task timeout calculation to assure that there is
4005 never negative timeouts. The affected file is
4006 lib/silcutil/silcschedule.c.
4008 * Fixed the channel user mode notification sending in server.
4009 It was sent point-to-point to the router (or to server by router)
4010 but it needs to be destined to a channel. The routines now
4011 supports sending the channel user mode notifys to the channels
4012 when announcing clients and channels. Affected files are
4013 silcd/server.c and silcd/packet_receive.c.
4015 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4016 It did not actually replace the old channel entry in the cache.
4017 Affected file lib/silcclient/client_notify.c.
4019 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Fixed a possible crash in silc_packet_send_prepare. It now
4022 assures always that there is enough space in the buffer and
4023 at the tail area of the buffer (for MAC).
4025 Fixed the inbound buffer reallocation in silc_packet_read.
4026 It was old code and did not handle the reallocation correctly.
4029 The affected file is lib/silccore/silcpacket.c.
4031 * Fixed buffer overflow in silc_parse_nickname in the file
4032 lib/silcutil/silcutil.c.
4034 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * make install generates new server keys only if there is not
4039 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4042 Added check that if the NOREPLY is set then we will not send
4043 the away message. This avoids infinite loop of away messages
4044 if both clients are away. The affected file is
4045 lib/silcclient/client_prvmsg.c.
4047 * Fixed client crash if /NICK was given without arguments.
4048 Affected file lib/silcclient/command.c.
4050 * Server does not send the invite list in INVITE command back
4051 to the client if the list was not altered. Added this notion
4052 to the protocol spec as well. Affected file silcd/command.c.
4054 Fixed possible crash in INVITE command by checking the
4055 value of silc_server_get_client_route command.
4057 * Fixed the INVITE notify type handling. The arguments are now
4058 taken in correct order and client does not crash. The affected
4059 file is irssi/src/silc/core/silc-channels.c.
4061 Removed the "Inviting xxx to channel" message from the
4062 client library away and let the application handle it.
4063 Affected file lib/silcclient/command.c. Added that message
4064 to Irssi SILC client's message formats.
4066 * Fixed CMODE command crash in client. It now checks the
4067 amount of arguments correctly and does not crash. The affected
4068 file is lib/silcclient/command.c.
4070 * Do not create new channel automatically in silc_channels_join
4071 but check whether the channel by that name already exists.
4072 Affected file irssi/silc/core/silc-channels.c.
4074 * Do not send the SERVER_SIGNOFF to router if the disconnected
4075 entity was the router. Affected file silcd/server.c.
4077 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4078 SILC client as it was missing from there.
4080 Added the handling of the KICK notify to the Irssi SILC client
4081 as it was missing. Added "you have been kicked" message to
4082 Irssi SILC client's message modules formats.
4084 Added the handing of the KILL notify to the Irssi SILC client
4085 as it was missing. Added the kill message module formats
4088 The affected file is irssi/src/silc/core/silc-channels.c.
4090 * The router did not save the channel mode the server announced.
4091 Affected file silcd/packet_receive.c.
4093 * Fixed a possible crash in INFO command in server. If the
4094 server did not provide the server info it crashed. Affected
4095 file silcd/command.c.
4097 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Fixed the GETKEY command in the server to check also the
4100 global list. Otherwise the GETKEY would not work correctly
4101 in normal SILC server. Affected file silcd/command.c.
4103 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Fixed GETKEY crash, it crashed if the command did not succseed.
4107 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4110 is now real and not just an macro interface to GMP.
4112 Removed the entire GMP from the source tree and imported new
4113 NSS MPI library instead. Reason for removing GMP is that it is
4114 extremely large and compiles extremely slow. The NSS MPI
4115 is only a few files and compiles in less than 10 seconds.
4116 The speed is also about the same as GMP. The MPI is imported
4117 to lib/silcmath/mpi.
4119 If the system has GMP installed we will still use the GMP.
4120 If it is not then the NSS MPI will be compiled.
4122 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Merged a long nickname (127 characters long) crash bugfix from
4125 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4127 * Merged a freed memory reference bugfix from Irssi CVS tree.
4128 Affected file irssi/src/core/commands.c.
4130 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Added the server's public key sving and verification to the
4133 server when performing the SKE. This was missing and the
4134 remote server's (or router's) public key was accepted without
4135 checking whether we have it previously or trust it at all.
4136 Affected file silcd/protocol.c.
4138 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Check in the silc_server_timeout_remote if protocol is active
4141 and make sure that the protocol's final callback is called so
4142 that all memory if freed. Affected file silcd/server.c.
4144 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * silc_server_whois_send_reply crashed the server if the nickname
4147 was 127 characters long. Affected file silcd/command.c.
4149 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Added sanity check to the silc_server_new_client. If the hostname
4152 is provided inside username then check that the provided hostname
4153 really is the same as the resolved one. If the hostname was not
4154 resolved then check it from the public key. Affected file is
4155 silcd/packet_receive.c.
4157 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4158 if the server disconnected us and the connection is not valid
4159 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4161 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4162 the library to the lib/silcutil/silcutil.[ch].
4164 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Close log file after open. Affected file
4167 lib/silcutil/silclog.c.
4169 * Check whether sock == NULL in silc_client_send_packet and return
4170 if it is. Affected file lib/silcclient/silcclient.c.
4172 * Check rec->entry == NULL in the Irssi SILC Client before
4173 sending the channel message. Affecte file is
4174 irssi/src/silc/core/silc-servers.c.
4176 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Merged a splitted window bugfix from Irssi CVS tree. The
4179 affected file is irssi/src/fe-text/textbuffer-view.c.
4181 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4182 It did not print nickname.
4184 * Improved the distributions system a bit.
4186 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4189 irssi/src/fe-text/gui-window.c.
4191 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4192 to in-active server. The affected file is
4193 irssi/src/silc/core/client_ops.c.
4195 * Resolve the client in USERS command reply if the entry does
4196 not have username resolved. The affected file is
4197 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4198 command to WHOIS command to really resolve stuff. The USERS
4199 is not used any more in any critical section so WHOIS can
4200 be used even though it might be slower than IDENTIFY.
4202 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4205 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Changed the protocol API a bit more consistent in the
4208 lib/silccore/silcprotocol.[ch].
4210 * Changed the following headers to ROBODoc format:
4212 lib/silccore/silcpayload.h
4213 lib/silccore/silcprotocol.h
4214 lib/silccore/silcsockconn.h
4216 All core library headers are now formatted.
4218 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Fixed a bug in Irssi SILC client; do not show that you are
4221 server/router operator if you really are not. Affected file is
4222 irssi/src/silc/core/client_ops.c.
4224 * Renamed silc_command_free_payload to silc_command_payload_free.
4225 Affected file lib/silccore/silccommand.h
4227 * Added silcmath.h to include the prototoypes of various routines
4228 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4231 * Changed the following headers to ROBODoc format:
4233 lib/silccore/silcchannel.h
4234 lib/silccore/silccommand.h
4235 lib/silccore/silcid.h
4236 lib/silccore/silcidcache.h
4237 lib/silccore/silcmode.h
4238 lib/silccore/silcnotify.h
4239 lib/silccore/silcpacket.h
4240 lib/silcmath/silcmath.h
4242 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Added checking to the server code not to start the server if
4245 ciphers and stuff are not configured properly. Affected files
4246 silcd/serverconfig.[h] and silcd/server.c.
4248 * Changed the layout of the header files of the public interfaces
4249 in the SILC libraries. The new layout supports ROBODoc
4250 documentation tool (and some others) so that it is easy to create
4251 a library reference manual. All the other headers and source
4252 code must still follow the CodingStyle document. Also source
4253 code must not include these ROBODoc stuffs, only the headers.
4254 Furthermore, all public interface headers must now be named
4255 by using `silc' prefix, example: silcapi.h, silccipher.h.
4256 Some files were renamed due to this. All the other headers
4257 must not be used as public interfaces. I will update the
4258 CodingStyle document later. Changed following headers, so far:
4260 lib/silcclient/silcapi.h
4261 lib/silccore/silcauth.h
4262 lib/silccore/silcprivate.h
4263 lib/silccrypt/silcdh.h
4265 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Removed silc_client_packet_send_flush from the client library
4270 as it is not needed. Affected file lib/silcclient/client.[ch].
4272 * Added printing of message of unresolved authentication method
4273 to the Irssi SILC client. Added it to the module formats.
4274 Removed the same message from the client library.
4276 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Added new distribution feature, DISTLABEL. Every distribution
4279 can define own preprocessor label that can be used in the
4280 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4281 file distributions, acconfig.h.pre and prepare.
4283 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added Makefile.defines_int to include the actual definitions
4286 for Makefile.defines.in. Tested the new distribution system,
4287 created distributions and tested installation.
4289 * Added AWAY message printing to the Irssi SILC client. Added
4290 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4292 * Added SCONNECT command to call the SILC's CONNECT command.
4293 Cannot use CONNECT directly since Irssi uses that internally.
4294 Affected file irssi/src/silc/core/silc-servers.c.
4296 Added ACTION local command. It is same as ME command but takes
4297 the channel as mandatory argument.
4299 Rewrote some of the Irssi's help files to suite for SILC
4302 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Added Makefile.defines[.in] that should for now on be included
4305 in all Makefile.am file in the source tree. That file includes
4306 all common compilation definitions for SILC source tree.
4308 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Minor changes to the ./prepare script to change the package
4311 name according the distribution name to the configure.in.
4313 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Created new distribution system. Added file `distributions'
4316 that defines all the distributions that can be created out of
4317 the SILC source tree. The ./prepare script now reads that
4318 file to determine how to prepare the distributions. The
4319 first argument to the ./prepare is the name of the distribution
4320 and second is the version of the distribution. If given
4321 without arguments it creates the default (toolkit) distribution
4322 with the default version (defined in ./prepare).
4324 All Makefile.am files that are subject to the distributions
4325 are now named as Makefile.am.pre. These are ./Makefile.am
4326 and lib/Makefile.am. Others may be changed later.
4328 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Added invite list, ban list, some key management and connection
4331 error message printing to module formats in the Irssi SILC client.
4333 * Added new silc_client_set_away_message to set the away message
4334 that is back to the person who sent private message. The
4335 affected file lib/silcclient/silcapi.h and the
4336 lib/silcclient/client_prvmsg.c.
4338 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Fixed the private message sending in the Irssi SILC client,
4341 added local command KEY to the Irssi SILC client.
4343 Added key management and key agreement message formats to the
4344 irssi/src/fe-common/silc/module-formats.[ch].
4346 Added USERS (alias WHO) printing, server/router operator
4347 indication and LIST command printing to the module formats.
4349 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Fixed channel joining notify handling, cumode notify handling
4352 from Irssi SILC client.
4354 * Added SILC specific module-formats to the Irssi SILC client so
4355 that SILC specific message hilighting, colors etc is possible.
4356 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4358 Added channel mode, channel user mode, actions, notices,
4359 whois and whowas printing to the the module-formats.c.
4361 * Fixed a bug in channel deletion in the server. The channel
4362 is not left to the cache even if the channel founder auth mode
4363 is set when there are no users anymore on the channel. Affected
4364 file silcd/server.c.
4366 * The silc_net_localhost now resolves the entire hostname including
4367 the domain name. Affected file lib/silcutil/silcnet.c.
4369 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Changed the ask_passphrase client operation to be ascynchronous.
4372 It has now a completion callback and a context that the
4373 application must call after it has got the passphrase from
4374 the user. Affected files lib/silcclient/silcapi.h,
4375 lib/silcclient/protocol.c, lib/silcclient/command.c and
4378 Added SilcAskPassphrase callback that the application calls
4379 to deliver the passphrase to the library.
4381 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4382 The public key verification and especially a certificate
4383 verification is asynchronous procedure.
4385 Added new SILC_SKE_STATUS_PENDING status to indicate the
4386 request is pending and a callback will be called to finalize
4389 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4390 indicate that remote end did not send its public key (or
4391 certificate), even though we require it. Added check for this
4392 condition in the SKE. This was a security bug, now fixed.
4394 Defined new SilcSKEVerifyCbCompletion callback that is called
4395 when the verification process is completed.
4397 The affected files lib/silcske/silcske_status.h and
4398 lib/silcske/silcske.[ch].
4400 * Changed the verify_public_key client operation to be async
4401 as well. Defined SilcVerifyPublicKey callback that is used to
4402 indicate the success of the public key verification process.
4404 Changed the server and client to use the new async client
4407 * Changed the Irssi SILC client's internal scheduler to be called
4408 twice as many times as it used to be. As a result the client
4409 should be a bit faster now. Affected file is
4410 irssi/src/silc/core/silc-core.c.
4412 * Added support to Irssi SILC client of asynchronous public key
4413 verification and passphrase inquiry. Affected file is
4414 irssi/src/silc/core/silc-core.c.
4416 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Do not say "You have left channel %s" in client library.
4419 Moved it to the application. Affected files are
4420 lib/silcclient/command.c and silc/client_ops.c.
4422 * Fixed silc_client_get_clients. Command context was not
4423 duplicated and was freed memory in the callback. Affected
4424 file lib/silcclient/idlist.c.
4426 * Do not say "you are now talking..." on JOIN command in the
4427 client library. The appliation must handle it.
4429 * Do not say ".. changed topic to" in command reply in the
4430 client libary. The application must handle it.
4432 * Fixed TOPIC command sending in the client library.
4434 * Fixed a memory leak in silc_client_command_free in the file
4435 lib/silcclient/command.c.
4437 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Imported a modified version of Irssi client to the source tree.
4440 The Irssi will be used to create a new client called
4441 Irssi SILC. Imported to irssi/.
4443 Added silc_core_init_finish function to the Irssi. Affected
4444 file irssi/configure.in.
4446 A lot changes in the Makefile.ams around the irssi tree.
4448 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Do not rehash if the new size is same as the old size of the
4451 hash table, in the silc_hash_table_rehash*. The affected file
4452 lib/silcutil/silchashtable.c.
4454 * Replaced hash_table_del_by_context calls from the server
4455 (when channel->user_list and client->channels) to the
4456 hash_table_del as it is sufficient and faster.
4458 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added silc_hash_table_list, silc_hash_table_get and the
4461 SilcHashTableList structure to provide an alternative way to
4462 traverse the hash table. The affected files are
4463 lib/silcutil/silchashtable.[ch].
4465 * Changed the server's idlist routines to use the hash table
4466 routines to optimize the code.
4468 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Replaced the client entry's `channel' list and channel entry's
4471 `user_list' list to hash tables for optimized lookup. Changed
4472 the code to use the hash table interface around the code.
4473 Affected file lib/silcd/idlist.[ch].
4475 * Added `auto_rehash' boolean argument to the function
4476 silc_hash_table_alloc to indicate whether the hash table should
4477 auto-rehash when it thinks is appropriate time. It will
4478 increase the hash table size if the there is twice as much
4479 entries in the table than the size of the table, and will
4480 decrease the size if there are twice as less entries than
4481 the size of the table.
4483 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4487 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * silc_idcache_purge_by_context deletes the entry now by context
4490 as it is supposed to do. Affected file lib/silccore/idcache.c.
4492 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4493 client is not anymore valid (WHOWAS givens the info) and not
4494 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4496 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Removed the `data' and `data_len' arguments from the ID Cache
4499 interfaces and added `name' argument. ID Cache does not handle
4500 anymore the binary data only a names associated with given ID.
4502 * When hashing a Client ID with silc_hash_id the entire ID is
4503 not hashed anymore, instead only the hash of the Client ID is
4504 hashed. This way we can access the Client ID from the cache
4505 with Client ID but with the hash of the ID (which is a hash of
4506 the nickname) as well without any difference in performance.
4508 Added also silc_idcache_find_by_id_one_ext to do one on one
4509 searching when we have the actual ID. Added also function
4510 silc_hash_client_id_compare. The affected files are
4511 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4513 * When hashing the name associated with a ID it is always done
4514 in lowercase. This way we can access the cache without worrying
4515 about case-sensitivity, even though, for example nicknames are
4518 * Fixed a bug in server with channel message sending. It put
4519 wrong ID type as destination ID. The affected file
4520 silcd/packet_send.c.
4522 * silc_idcache_del_by_context now deletes from all hash tables
4523 by context. Affected file lib/silccore/idcache.c.
4525 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Changed the client library to use the new ID Cache interface.
4528 Changes around the source tree.
4530 * Added silc_hash_table_rehash_ext to rehash with specific
4531 hash function. Affected file lib/silcutil/silchashtable.[ch].
4533 * Added silc_hash_string_compare to compare two strings in the
4534 hash table. Affected file lib/silcutil/silcutil.[ch].
4536 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Added new function silc_idcache_del_by_context into the
4539 lib/silccore/idcache.[ch].
4541 * Changed the server's ID list routines to use the new ID Cache
4542 interface. Changes around the source tree.
4544 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Added silc_hash_table_del[_by_context]_ext functions in to the
4547 lib/silcutil/silchashtable.[ch].
4549 Removed silc_hash_table_find_all* routines and added new
4550 silc_hash_table_find_foreach to replace them.
4552 Added silc_hash_table_replace_ext function as extended
4553 replacing function. Separated the simple hash table interface
4554 from the extended hash table interface in the file
4555 lib/silcutil/silchashtable.h.
4557 * Fixed minor bugs and changed it to use some of the new
4558 hash table functions in lib/silccore/idcache.c
4560 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Added new function silc_hash_table_find_all to return all keys
4563 in the hash table by the specified key. As the hash table is
4564 collision resistant it also makes it possible to have several
4565 duplicate keys in the hash table. This function may be used to
4566 find all of the keys from the hash.
4568 Added user_context arguments to the SilcHashFunction,
4569 SilcHashCompare and SilcHashDestructor to deliver user specified
4572 Added new fuctions silc_hash_table_find[_all]_ext to do
4573 extended lookup with specified hash and compare functions and
4574 specified user contexts.
4576 Added new function silc_hash_table_add_ext to add the key
4577 with specified hash function and user context.
4579 Added new function silc_hash_table_foreach to traverse all
4580 entrys in the hash table. Added SilcHashForeach callback
4583 Added new function silc_hash_table_del_by_context to delete
4584 the entry only if the context associated with the key matches.
4586 Affected files are lib/silcutil/silchashtable.[ch].
4588 * Removed silc_hash_[server/client/channel]_id and added just
4589 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4590 silc_hash_id_compare to compare two ID's using as the hash table
4591 comparison function. Added also silc_hash_data to hash
4592 binary data and silc_hash_data_compare to compare it.
4594 * Removed silc_idlist_find_client_by_hash as it is not needed
4595 anymore. Affected file silcd/idlist.[ch].
4597 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4598 to use internally the SilcHashTable. The new ID Cache is a lot
4599 faster than the old one. Some of the ID Cache interface was also
4600 rewritten and obsolete and stupid functions were removed.
4602 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Added entry_count field to the SilcHashTable to keep the number
4605 of the entries in the table. Implemented the function
4606 silc_hash_table_rehash. Added new function
4607 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4609 Fixed a minor bug in silc_hash_table_free.
4611 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4612 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4613 into the lib/silcutil/silcutil.[ch].
4615 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Implemented a collision resistant hash table into the
4618 lib/silcutil/silchashtable[ch]. See the header and the source
4619 for the SilcHashTable API.
4621 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Merged dotconf version 1.0.2 into lib/dotconf.
4625 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Do not compile anything in lib/silcsim/* if the SIM support
4628 is not enabled. The tree should now compile without problems
4631 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Compiled the SILC under cygwin. Compiled and tested briefly
4634 without problems. More tests needed. The SIMs didn't compile
4637 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4639 * Fixed possible crash in silc_get_username in the
4640 lib/silcutil/silcutil.c.
4642 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Fixed a va_arg in silc/client_ops.c.
4646 * Oops, RC5 routines were named AES and caused some problems
4647 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4649 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Added new SilcIDIP structure into the lib/silccore/id.h and
4652 replaced the old `ip' fields from all SILC ID's to that type.
4653 This is a step towards IPv6 support.
4655 The silc_id_get_len takes now the ID as an extra argument.
4656 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4657 both IPv4 and IPv6 based ID's.
4659 The affected files are lib/silccore/id.[ch] and other files
4660 around the tree using these routines.
4662 * Removed the ID length arguments in server from various
4663 silc_server_send_notify_* routines -> they are not needed
4666 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Fixed memory leak in silc_encode_pem_file in the file
4669 lib/silcutil/silcutil.c.
4671 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Check minor version as well in the SKE. Affected files are
4674 silcd/protocol.c and lib/silcclient/protocol.c.
4676 * Added --identifier option to the server so that an identifier
4677 can be when creating the public key for the server. Affected
4678 file is silcd/silcd.c.
4680 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4681 lib/silccrypt/silcpkcs.c.
4683 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Register default ciphers and stuff when using -C option with
4686 the server. Affected file sildc/silcd.c.
4688 * Put back the servers public key filename format, it is better
4689 than the new one. For now, the client keys are saved with the
4690 new filename format. The affected file silc/client_ops.c.
4692 * Implemented the Cipher API for the rest of the ciphers that
4693 did not implement it or implemented it the wrong way.
4695 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Register default ciphers and stuff when using the -S option
4698 in the client. Affected file silc/silc.c. Same also when
4699 creating new key pair with -C option.
4701 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Fixed the silc_verify_public_key client operation function to
4704 save the public keys differently. The fingerprint is now
4705 used as filename and not the hostname. This way also the
4706 client keys are saved uniquely and not with hostnames. The
4707 affected file is silc/client_ops.c.
4709 * Trimmed the silc_hash_fingerprint function to remove extra
4710 whitespaces from the end of the fingerprint. The affected
4711 file is lib/silccrypt/silchash.c.
4715 * Added silc_cipher_register_default function to register all
4716 default ciphers. It can be used when configuration files
4717 does not exist and the application does not want any specific
4718 ciphers in any specific order.
4720 The SilcDList is now used as silc_cipher_list dynamically
4721 allocated cipher list. Removed the static list all together
4722 and now all ciphers must be allocated to the dynamic list.
4723 The silc_cipher_alloc routine was changed to check only the
4726 All silc_cipher_* routines that used to return int returns
4729 The affected files lib/silccrypt/silccrypt.[ch].
4731 * The same thing was done to silc_hash_* as for silc_cipher_*
4732 routines. Affected files lib/silccrypt/silchash.[ch].
4734 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4735 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4736 Added also silc_pkcs_[un]register[_default] functions.
4737 Removed the data_context from the PKCS API.
4739 * Added silc_hmac_register_default function to register default
4740 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4741 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4742 to unregister all hmacs at once.
4744 * Register the default ciphers, hash functions, PKCSs and HMACs
4745 if client's configuration file does not exist. The affected
4748 * The client did not load the hash functions from the SIM
4749 modules at all. Added support for this. Affected file is
4750 silc/clientconfig.c.
4752 * When decoding public key with silc_pkcs_public_key_decode, check
4753 the supported algorithm only if PKCS are registered. Affected
4754 file lib/silccrypt/silcpkcs.c. The same was done with the
4755 silc_pkcs_private_key_decode.
4757 * Fixed the SILC List routines to keep the list always in order.
4758 It used to change the list's order when traversing the list but
4759 not it preserves the order. Affected file lib/trq/silclist.h.
4761 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Added the client library to use the SilcSocketConnection's
4764 reference counter (by silc_socket_dup) to prevent the bug that
4765 the socket object may be freed underneath async operation.
4767 * The name resolv library checking fixes in the configure.in.pre.
4770 * Created new version of the protocol drafts for future
4771 development. The -03 drafts are the ones that will be changed
4772 in the trunk now and the -02 will remain as they are.
4774 * Send list of CUMODE notifys to the router when announcing
4775 the channel users to the router. Affected file silcd/server.c.
4776 If the router receiving channel founder CUMODE for a channel
4777 that already has channel founder it will send CUMODE notify
4778 to the sender to remove the channel founder rights from the
4779 announced client. Affected file silcd/packet_receive.c.
4781 * The CUMODE notify may now use Server ID as well as the entity
4782 who changes the mode. Updated protocool specs.
4784 * Updated INSTALL and README files.
4786 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * New web pages in the http://silc.pspt.fi. The pages was
4793 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Implemented the [DenyConnectin] config section in the server.
4796 Added silc_server_config_denied_conn to check whether incoming
4797 connection is denied. Affected file silcd/serverconfig.[ch].
4799 * Do not check the ports when checking the incoming configuration
4800 data if the port is 0, meaning any. Affected file is
4801 silcd/serverconfig.c.
4803 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Fixed buffer overflow in silc_string_compare in the file
4806 lib/silcutil/silcutil.c.
4808 * Fixed double free in silc_server_command_leave in the file
4811 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Fixed the version checking in the server. Affected file is
4816 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4818 * Fixed the configuration data fetching when accepting new
4819 connections in the server. Affected file silcd/server.c.
4821 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Added `sender_entry' argument to the function
4824 silc_server_packet_relay_to_channel so that we can check
4825 whether some destination actually belongs to the same route
4826 the sender belongs (ie, we must not resend the packet to the
4827 sender). Affected file silcd/packet_send.[ch].
4829 * Added `servername' field to the SilcClientEntry in the server
4830 to hold the name of the server where client is from. Affected
4831 file is silcd/idlist.h.
4833 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Moved the channel message encrypting in the router betwen
4836 router connections from silc_server_channel_message to the
4837 silc_server_packet_relay_to_channel since we want to check
4838 whether we have anybody channel before encrypting anything.
4839 Affected files silcd/packet_[receive/send].c.
4841 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Fixed the [AdminConnection] server config section to support
4844 multiple entries. Affected file silcd/serverconfig.c.
4846 * Added support into the server to check the validity of the
4847 incoming connection before executing any KE or authentication
4850 * The connection configuration is now saved to the KE and
4851 connection auth protocol contexts and not fetched anymore in
4852 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4854 * The local hosts listenning address and port is also resolved
4855 now when starting the server. We want to have the socket object
4856 to include the real address and port for the listener. Added
4857 new function silc_net_check_local_by_sock into the files
4858 lib/silcutil/silcnet.[ch].
4860 * Fixed a broadcast bug in server -> do not broadcast if we
4863 * Fixed a routing bug. Do not route broadcast packets ever.
4864 Broadcast packets must be processed always and not routed since
4865 they may be destined to some other host than yourself and thus
4866 would get routed without no good reason. Affected file is
4869 * Added function silc_server_config_is_primary_route to check
4870 whether primary router connection has been configured (a router
4871 configuration that we are initiating). If there is not, we
4872 will assume that there is only two routers in the SILC network
4873 and we will use the incoming router connection as our primary
4874 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4876 * Changed the order of the broadcasting. Broadcast _after_ the
4877 packet has been processed not before. Affected file is
4880 * Fixed a [ClientConnection] parsing bug. The port was never
4881 parsed correctly thus resulting to port 0. Affected file
4882 silcd/serverconfig.c.
4884 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4885 argument and did not set the broadcast packet flag. Affected
4886 file silcd/packet_send.c. Fixed same bug in the function
4887 silc_server_send_notify as well.
4889 * If we receive NEW_ID packet for our own ID in the server, ignore
4892 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4896 * Removed the nickname from the Private Message Payload.
4897 Updated the code and the protocol specs.
4899 * Updated protocol specs for submitting to the IETF.
4901 * Tweaked the Random Number Generator a bit. Affected file
4902 lib/silccrypt/silcrng.c. Exported a new function
4903 silc_rng_[global]_add_noise which can be used to add more
4906 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Do not parse packets with different timeout when protocol
4909 is active -> may cause problem with rekey. Affected file
4912 * When server receives signoff notify it must not create
4913 new channel key if the client is on any channels since the
4914 sender of the signoff notify will create it.
4916 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Added printing of error messages during SKE protocol from the
4919 failure packet sent by server during SKE. Affected file
4922 * Removed the client's failure_callback handling with timeout
4923 and handle it immediately when received.
4925 * The SKE library returned wrong type in SUCCESS and FAILURE
4926 packets. They must be 32 bit MSB not 16 bit MSB.
4928 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Ok, rewrote the logic of the re-key and now it seems to work.
4931 I tested it on high traffic with frequent re-keys without
4932 problems. Added hmac_receive (and renamed hmac to hmac_send)
4933 in SilcClientConnection in lib/silcclient/client.h and
4934 in SilcIDListData in silcd/idlist.h. Also, removed the
4935 SilcPacketParserContext's cipher and hmac fields as they are
4936 not needed anymore and actually caused some problems when
4937 the ciphers and hmac's changed underneath the packet parser.
4939 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * If re-key protocol is active then process the incoming packets
4942 synchronously since we must assure that icoming packets encrypted
4943 with the old key is processed before the new keys is set to
4944 use. This is true other packets than for REKEY packets.
4945 Affected file silcd/server.c. The same was done to client library
4946 as well, affected file lib/silcclient/client.c.
4948 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Fixed bug in client and server to accept the force send if
4951 the packet is send from silc_[server/client]_packet_process
4952 function. Otherwise the packets are never delivered, oops.
4954 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Disable force sending of packets when REKEY protocol is active.
4957 We must assure that no packet is sent directly when rekey is
4958 performed. All packets must be sent through packet queue.
4959 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4960 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4961 function is silc_[server/client]_packet_send_real to check
4964 * Replaced the SIM paths from example config files to
4965 /usr/local/modules. Also, make install creates now
4966 /usr/local/silc/logs directory to hold all the SILC server
4969 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Made the configure.in.pre work on Solaris. Patch by salo.
4973 * Made all ciphers compatible with non-x86 machines. Defined
4974 CBC mode macros into lib/silccrypt/ciphers_def.h.
4976 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Fixed the make install.
4980 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * When MAC computation fails the silc_packet_decrypt returned 0
4983 even though it was supposed to return -1. Fixed this. The
4984 affected file is lib/silccore/silcpacket.c.
4986 * Do not replace the config files in /etc/silc (in make install)
4987 if they already exist. Affected file ./Makefile.am.
4989 * Do not send re-key packets immediately but through packet queue.
4990 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4992 * Changed silc_net_check_host_by_sock to return FALSE if the
4993 IP/DNS could not be resolved. Though, it returns the IP address
4994 now even if it could not resolve it (but returns also FALSE).
4995 Affected file lib/silcutil/silcnet.[ch].
4997 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Added silc_pkcs_decode_identifier to decode the public key's
5000 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5001 Added also silc_pkcs_free_identifier. Added also new context
5002 SilcPublicKeyIdentifier.
5004 * Added -S option to the silc client. It is used to dump the
5005 contents of the specified public key file.
5007 * Changed the PKCS api to return the public key length when
5008 setting the public key.
5010 * Fixed a fatal bug in the public and private key file loading.
5011 Affected file lib/silccrypt/silcpkcs.c.
5013 * Execute the packet parsing for client with zero (0) timeout
5014 if the protocol is active. Affected file silcd/server.c.
5016 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Made the key generation options to the silcd program. Added
5019 -C option, equivalent to client's option.
5021 * Added new [ServerKeys] config section to the server. It
5022 configures the server's public and private key.
5024 * Defined generic Public Key Payload into the protocol
5025 specification to send specific type of public keys and
5028 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5029 public key or certificate.
5031 * Implemented the GETKEY command to the server and to the
5032 client library and on user interface.
5034 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Made preliminary `make install' work.
5038 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Added SilcServerRekey context into silcd/idlist.h.
5042 * Added the PFS support as defined in the specification to the
5043 SKE protocol. Affected files lib/silcske/*.c.
5045 * Added `ske_group' field to the SilcServerRekey context to hold
5046 the number of the SKE group that is used with PFS in re-key.
5047 Affected file silcd/idlist.h.
5049 * Added PFS re-key support to the server. Affected file is
5052 * Added silc_protocol_cancel to cancel execution of the next
5053 state of the protocol. Affected file is
5054 lib/silccore/silcprotocol.[ch].
5056 * Added the re-key support with and without PFS to the client
5057 library. Re-key is performed once in an hour, by default.
5059 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5060 Added silc_client_rekey_callback and silc_client_rekey_final.
5061 Affected files are lib/silcclient/protocol.[ch] and
5062 lib/silcclient/client.[ch].
5064 * Removed the `hmac_key' and `hmac_key_len' fields from the
5065 SilcClientConnection structure; not needed. Affected file is
5066 lib/silcclient/client.h.
5070 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Do not ask whether user wants to use the negotiated private key
5073 for private messages, just use it. Affected file is
5074 silc/local_command.c.
5076 * Added `send_enc_key' and `enc_key_len' fields to the
5077 SilcIDListData structure since they are needed in the re-key
5078 phase. Affected file is silcd/idlist.[ch].
5080 * Implemented the simple re-key protocol into the server.
5081 Affected files silcd/server.c and silcd/protocol.[ch]. The
5082 re-key will be performed once in an hour, by default.
5084 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5085 Added silc_server_rekey, silc_server_rekey_callback and
5086 silc_server_rekey_final.
5088 * Removed Tunneled flag from the protocol. Updated the code
5089 and the specifications.
5091 * Adde `pfs' field to the SilcIDListData to indicate whether
5092 the PFS is to be performed in the re-key. Affected file is
5095 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5098 int64 of at least the xintXX size. If void * is less that 4
5099 bytes uint32 * will be used. Defined bool as boolean.
5101 * Changed _ALL_ unsigned long and unsigned int to uint32,
5102 unsgined short to uint16 in the source tree.
5104 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5105 not handle clients that has entry->data.registered == FALSE.
5106 They are not in the network anymore. Affected file is
5109 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Implemented the sending of the SERVER_SIGNOFF notify in the
5112 server. Affected file is silcd/server.c.
5114 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5115 Added also silc_notify_payload_encode_args into the
5116 lib/silccore/silcnotify.[ch].
5118 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5119 Affected file silcd/packet_receive.c.
5121 * Implemented the SERVER_SIGNOFF notify handling in the client
5122 library. Affected file lib/silcclient/client_notify.c. Also,
5123 implemnted the printing of the SERVER_SIGNOFF info to the
5124 application. Affected file silc/client_ops.c.
5126 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5127 if the deleting was successful. Affected file silcd/idlist.[ch].
5129 * Added support for public key authentication in the connection
5130 authentication protocol in the client library. Affected file
5131 lib/silcclient/protocol.c.
5133 * Changed the server's silc_idlist_get_clients_by_* interface
5134 to support already allocated array so that new entries may be
5135 added to pre-allocated array. Affected file silcd/idlist.[ch].
5136 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5137 and command replies.
5139 * All command reply functions in the server now calls the
5140 pending command callback even if error occured. This way the
5141 error will be delivered to the client as well. Affected files
5142 silcd/command.c and silcd/command_reply.c.
5144 * Fixed INFO command to return local server's info if no server
5145 was provided. Affected file lib/silcclient/command.c.
5147 * Removed RESTART command for good. Updated the code and the
5150 * Rewrote parts of the task system. It is a bit simpler now.
5151 Removed unsued task priorities. The affected files are
5152 lib/silcutil/silctask.[ch].
5154 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Moved the USERS printing from the library to the application.
5157 Affected files lib/silcclient/command.c and silc/client_ops.c.
5159 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Added channel key re-key support. The re-key is perfomed
5164 only by the router and is done once in an hour. Added `rekey'
5165 field to the SilcChannelEntry in the server. Affected files
5166 silcd/server.c and silcd/idlist.h.
5168 * Added silc_task_unregister_by_context into the file
5169 lib/silcutil/silctask.[ch].
5171 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Added SILC_UMODE_GONE mode to indicate when the client is not
5174 present in the SILC network. Added also support to the local
5175 command AWAY that will set this mode. Added support of showing
5176 "xxx is gone" in WHOIS command. The USERS command shows the
5177 gone status as well.
5179 * Fixed setting server and router operator privileges in the
5180 server's UMODE command. Affected file silcd/command.c.
5182 * Merged the SKE KE1 and KE2 payloads into one payload. The
5183 new KE payload is equivalent to the old KE2 payload.
5185 Cleaned up the SKE Start Payload parsing. It now uses the
5186 simple buffer unformatting to do the parsing. A lot faster
5189 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5190 to the SKE that is used to indicate whether both of the SKE
5191 parties should perform authentication. By default only the
5192 responder performs authentication. By setting this flag also
5193 the initiator must do authentication. By default it is unset
5194 since in normal SKE case, client to server connection, only
5195 the responder should do authentication. When doing SKE between
5196 two clients both should perform authentication. Updated the
5197 code and the protocol specs.
5199 * A little fix to IDENTIFY command in the server. Search the
5200 client first by hash not nickname. Affected file is
5203 * Fixed the silc_client_close_connection to support closing
5204 the client to client connections wihtout deleting too much
5205 data. Affected file lib/silcclient/client.c.
5207 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5208 are received if protocol used to be active but is not anymore
5209 the application would crash due to NULL pointer dereference.
5210 Affected files silcd/server.c and lib/silcclient/client.c.
5212 * Added `hash' field to the SilcClientConnection to include
5213 the hash function negotiated in the SKE protocol.
5215 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5216 to set the channel founder authentication data. A client can
5217 claim the founder rights later by providing the authentication
5218 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5219 This way the channel founder can regain the channel founder
5220 privileges even it is left the channel. This works only on
5221 local server and the client must be connected to the same
5222 server to be able to regain the founder rights. Updated the
5223 protocol specs accordingly.
5225 Added support to the CMODE command in the client to set the
5226 founder auth data. Read the README to see how to set it.
5228 Added support to the CUMODE command to claim the founder
5229 rights. Read the README to see how to do it.
5231 Added support for the founder authentication to the Channel
5232 Entry in the server. Affected file silcd/idlist.h.
5234 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5235 server's CMODE command. Affected file silcd/command.c.
5237 * Added the following new functions into lib/silccore/silcauth.[ch]:
5238 silc_auth_get_method and silc_auth_get_data.
5240 * The server now saves the remote hosts public key to the
5241 SilcIDListData pointer. Affected file silcd/protocol.c.
5243 * The normal server now does not remove the channel entry from
5244 the cache if the founder authentication data is set. It used
5245 to remove it if the founder was the last one on the channel on
5246 the server and left the channel. The auth data is saved and
5247 if the channel is re-joined later the old entry is used with
5248 the old auth data. Affected files silcd/command_reply.c and
5251 * Removed the `pkcs' field from the SilcIDListData structure
5252 in the server; it is not used. Affected file silcd/idlist.h.
5254 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Fixed packet processing on slow links. Partial packets were
5257 never re-processed because the incoming data buffer was cleared
5258 by the application. Application must not directly clear the
5259 sock->inbuf, the packet processing routines handle it. Fixed
5260 this in client library and in server.
5262 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Fixed the WHOIS and IDENTIFY send reply function to really
5265 check whether to send list or just one entry. Affected file
5268 * Cleaned up the LEAVE command's channel key distribution. The
5269 affected file silcd/command.c.
5271 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5272 can enforce the channel mode as well. In that case the ID
5273 includes the ID of the server. The code now enforces the
5274 mode change if the router have different mode than the server.
5276 * The notify client operation with CMODE_CHANGE notify can now
5277 return NULL client_entry pointer if the CMODE was not changed
5278 by client. Application must check for this.
5280 * Added <Server ID> argument to INFO command to support server
5281 info fetching by Server ID.
5283 * Added silc_server_announce_get_channel_users to get assembled
5284 packets of channel users of the specified channel. Affected
5285 file silcd/server.[ch].
5287 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5288 was freed underneath the ID Cache.
5290 * Re-announce clients when the server received CHANNEL_CHANGE
5291 notify from the router. Affected file silcd/packet_send.c.
5293 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5296 crashed since it did not handle the fact that there is no cipher
5297 called "3" and didn't check the error condition. Now fixed.
5299 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5300 flag. It can be used to send message requests.
5302 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Implemented the RESTART command in the client.
5306 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5307 notice type messages. Added notice printing to the user
5310 * The channel keys are not re-generated if the channel's mode
5311 is PRIVKEY, ie private key on the channel exists. Affected
5312 files silcd/server.c and silcd/command.c.
5314 * Fixed a little bug in channel message delivery when channel
5315 private keys are set in the server. Affected file is
5316 silcd/packet_send.c.
5318 * Changed the setting on channel->on_channel = TRUE from the
5319 silc_client_save_channel_key to the JOIN command reply. The
5320 key payload is not received if the private channel key is set.
5321 Affected file lib/silcclient/command_reply.c and the
5322 lib/silcclient/client_channel.c.
5324 * When the CMODE_CHANGE notify is sent and the channel private
5325 key mode is removed the channel key must be re-generated in
5326 other cells as well. Added this support for the router in the
5327 silcd/packet_receive.c.
5329 * Added new local command NOTICE to send notice message on
5330 channel. Affected file silc/local_command.[ch].
5332 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5334 * Added new local command ME to the client. It is used to send
5335 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5336 some action. Affected file silc/local_command.[ch].
5338 * Changed channel_message and private_message client operations
5339 to deliver the message flags to the application. Added also
5340 the `flags' arguments to the silc_client_send_channel_message
5341 and silc_client_send_private_message functions. Affected file
5344 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Redefined the Private Message Payload to support private message
5347 keys and to support the new private message flags. Updated
5348 the protocol specs. Flags makes it possible to have for example
5349 CTCP style messages.
5351 * Added new type SilcPrivateMessagePayload and defined an API
5352 for it in the lib/silcclient/silcprivate.[ch].
5354 * Tested private message private keys successfully. Tested the
5355 private message key set, unset and list commands with the new
5358 * Redefined the Channel Message Payload to include the channel
5359 message flags (equal with private message flags) to support
5360 for example CTCP style messages.
5362 * Defined some of the message (for channel and private message)
5363 flags. Updated the protocol specs and added the flags to the
5364 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5366 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Added SilcKeyAgreementStatus type to the key agreement routines
5369 to indicate the current status and error if one occured.
5370 The status types are defined in the lib/silcclient/silcapi.h.
5372 * Added new local command KEY that is used to set and unset private
5373 keys for channels, set and unset private keys for private messages
5374 with remote clients and to send key agreement requests and
5375 negotiate the key agreement protocol with remote client. The
5376 key agreement is supported only to negotiate private message keys,
5377 it currently cannot be used to negotiate private keys for channels,
5378 as it is not convenient for that purpose.
5380 * Fixed a minor pending callback setting bug in the function
5381 silc_client_get_client_by_id_resolve, now the function works.
5382 Affected file lib/silcclient/idlist.c.
5384 * Added function silc_net_get_local_port to get local bound
5385 port by socket. Added to lib/silcutil/silcnet.[ch].
5387 * Added `sockets' and `sockets_count' fields to the SilcClient
5388 object. They hold the sockets of the listenning sockets in
5389 the client. Listenning sockets may be for example the key
5390 agreement server. Affected file lib/silcclient/client.[ch].
5391 Added functions the silc_client_add_socket and the
5392 silc_client_del_socket. They are exported to the application
5395 * Added ~./silc/clientkeys to support other client's public keys.
5397 * Renamed verify_server_key client operation to verify_public_key
5398 and added one argument to indicate the type of the connection
5399 (server, client etc.).
5401 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Added silc_server_connection_auth_request to handle the
5404 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5405 silcd/packet_receive.[ch].
5407 * Added silc_server_send_connection_auth_request into the
5408 silcd/packet_send.c to send the connection auth request packet.
5410 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5413 * Fixed the public key authentication in responder side in the
5414 server. The `auth_data' pointer includes the SilcPublicKey
5415 not the path to the public key. Affected file silcd/protocol.c.
5417 * Implemented the public key authentication in the initiator side
5418 in the server. Affected file silcd/protocol.c.
5420 * Removed the [RedirectClient] config section from the server
5421 configuration. Is not needed and I don't want to implement it.
5423 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Cleaned up the CMODE command in the server. It now works
5426 correctly and supports all the modes defined in the protocol.
5427 Affected file is silcd/command.c.
5429 * Added `hmac_name' field to the SilcChannelEntry in the server
5430 to hold the default HMAC of the channel. It can be set when
5431 creating the channel (with JOIN command). Affected files
5434 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5435 type to indicate the change of the current cipher and hmac
5436 on the channel. Client can safely ignore the <cipher> argument
5437 (if it chooses to do so) since the CHANNEL_KEY packet will
5438 force the channel key change anyway. The <hmac> argument is
5439 important since the client is responsible of setting the new
5440 HMAC and the hmac key into use.
5442 * Fixed the CMODE command in the client library as well.
5444 * Tested CMODE command in router environment successfully.
5446 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Show the version of the remote client (or server) when connecting
5449 to the server. It is logged to the log file. Affected file
5450 is silcd/protocol.c.
5452 * Fixed the KILLED notify handling in the client library. The
5453 client must be removed from all channels when receiving the
5456 Also, do not remove the client entry when giving the KILL
5457 command but when the KILLED notify is received.
5459 * Removed silc_idlist_find_client_by_nickname from the server.
5460 Not needed anymore. Affected files silcd/idlist.[ch].
5462 * Implemented the CHANNEL_CHANGE notify type handling to the
5463 server. Affected file silcd/server.c.
5467 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Added silc_server_send_notify_invite to send the INVITE
5470 notify between routers.
5472 * Implemented the INVITE command correctly to the server.
5474 * Implemented the INVITE notify type handling in the server.
5476 * Implemented the INVITE command to the client library and on the
5479 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Added function silc_server_get_client_resolve to find the
5482 client entry by ID from all ID lists and then resolve it
5483 (using WHOIS) if it cannot be found. Affected file is
5486 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Implemented the BAN command to the client library.
5490 * The JOIN command in the server now checks the invite list
5493 * Changed the silc_command_reply_payload_encode_va and the
5494 silc_command_payload_encode_va to support that if argument is
5495 NULL it ignores and checks the next argument. Affected file
5496 lib/silccore/silccommand.c.
5498 * Added silc_server_send_notify_ban to send the BAN notify
5499 type between routers.
5501 * Chaned the silc_notify_payload_encode to support that if
5502 argument is NULL it ignores and checks the next argument.
5503 Affected file lib/silccore/silcnotify.c.
5505 * Tested ban lists in router environment successfully.
5507 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Implemented BAN command to the server, in silcd/command.[ch].
5511 * Removed the BAN and INVITE_LIST modes from the CMODE command
5514 * Added function silc_string_match to regex match two strings.
5515 Affected files lib/silcutil/silcutil.[ch].
5517 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Redefined parts of the SilcChannelEntry in the server to support
5520 the new ban and invite lists.
5522 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Redefined the INVITE command. The same command can be used to
5525 invite individuals to the channel but also to manage the invite
5526 list of the channel (to add to and remove from the invite list).
5527 Updated the protocol specs.
5529 * Added new command SILC_COMMAND_BAN that can be used to manage
5530 the ban list of the channel. Updated the protocol specs.
5532 * Removed the channel modes: the SILC_CMODE_BAN and the
5533 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5534 in the CMODE command. The equivalent features are now available
5535 using INVITE and BAN commands. Updated the protocol specs.
5537 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5538 in the network about change in the current ban list. The notify
5539 type is not used by the client.
5541 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5542 support the invite lists.
5544 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Added new function silc_string_regexify that converts string
5547 including wildcard characters into regex string that can
5548 be used by the GNU regex library. Added into the file
5549 lib/silcutil/silcutil.[ch].
5551 Added silc_string_regex_combine to combine to regex strings
5552 into one so that they can be used as one regex string by
5553 the GNU regex library. Added into the file
5554 lib/silcutil/silcutil.[ch].
5556 Added silc_string_regex_match to match two strings. It returns
5557 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5559 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Imported GNU regex to the soruce tree into lib/contrib.
5562 Fixed some compiler warning from the regex.c.
5564 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Fixed MOTD command in the server to work in router environment.
5568 * Fixed the MOTD command in the client library to support
5569 the server argument in the command.
5571 * Added `nickname_len' argument to the silc_idlist_add_client
5572 in the server, as the `nickname' argument may be binary data
5575 * Added silc_idlist_get_channels to return all channels from
5578 * Implemented LIST command to the server. Affected file is
5581 * Implemented the LIST command to the client library and on the
5584 * Added [<user count>] argument to the LIST command reply.
5585 With private channels the user count is not shown.
5587 * Updated TODO and README.
5589 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * The client entry's data.registered must be TRUE even with
5592 global client entry on global client list. The data.registered
5593 is used to check whether the client is anymore in the network,
5594 for example with WHOWAS command so it must be valid.
5596 * Fixed the WHOWAS command in the server. It now actually works
5597 in router environment. Added function into silcd/command_reply.c
5598 silc_server_command_reply_whowas_save.
5600 * Added silc_idlist_purge function to the silcd/idlist.c
5601 to periodically purge the ID Cache.
5603 * Fixed INFO command in the server. It works now in router
5604 environment. Added <server name> argument to the INFO command
5605 reply. Updated the protocol specs.
5607 * Fixed minor bug in silc_idcache_purge to not purge if the
5608 expire value is zero.
5610 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5611 they were buggy because of the WHOWAS information.
5613 * Fixed local command MSG to handle the async resolving of
5614 the remote client properly. It used to fail the first MSG.
5615 Affected file silc/local_command.c.
5617 * Added `data_len' field to SilcIDCache context.
5619 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Update TODO. Todo in commands in the server.
5623 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5626 used by routers as broadcast packet to inform other routers
5627 about the changed user mode.
5629 Implemented the notify handling in the server. Affected file is
5630 silcd/packet_receive.c. Added the function
5631 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5633 * Added new generic Channel Payload and deprecated the New Channel
5634 Payload. The New Channel Payload is now the generic Channel
5637 * Added new argument `mode' to the silc_server_send_new_channel
5638 as it is required in the Channel Payload now.
5640 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5641 and created a new and real SilChannelPayload to represent the
5642 new generic Channel Payload. Implemented the encode/decode
5643 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5645 * Added silc_server_get_client_channel_list to return the list
5646 of channels the client has joined for WHOIS command reply.
5647 Affected file silcd/server.[ch].
5649 * Implemented the channel list sending in the WHOIS command reply
5650 in server and in the client.
5652 Implemented the channel list displaying on the user interface
5653 as well. Affected file silc/client_ops.c.
5655 * Added silc_channel_payload_parse_list to parse list of Channel
5656 Payloads. It returns SilcDList list of SilcChannelPayloads.
5657 Client for example can use this function to parse the list of
5658 channels it receives in the WHOIS command reply. The caller
5659 must free the list by calling silc_channel_payload_list_free.
5660 Affected files lib/silccore/silcchannel.[ch].
5662 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added one new argument <user mode> to the WHOIS command reply
5665 to return the mode of the user in SILC. Updated the protocol
5668 Implemented it to the server and client.
5670 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Fixed the mode printing on the user interface on joining.
5673 Affected file silc/client_ops.c.
5675 * Implemented the UMODE command and user modes in general to the
5676 client library and to the user interface.
5678 * Implemented the UMODE command to the server.
5680 * The server now sends UNKNOWN_COMMAND error status if client sends
5681 unknown command. Affected file silcd/command.c.
5683 * All server commands now handle the command identifier the right
5684 way when sending the command reply to the client. The client can
5685 use to identify the command replies with the identifier.
5687 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Added silc_server_get_client_route to resolve the route to
5690 the client indicated by the client ID. Affected file is
5693 * Added silc_server_relay_packet as general function to relay
5694 packet to arbitrary destination. This deprecates functions
5695 like _send_private_message_key, _relay_notify etc. Affected
5696 file is silcd/packet_send.[ch].
5698 Removed silc_server_send_key_agreement,
5699 silc_server_send_private_message_key and
5700 silc_server_packet_relay_notify functions from the file
5701 silcd/packet_send.[ch].
5705 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5706 server. Affected file silcd/packet_receive.[ch].
5708 * Implemented the KILL command to the client. Implemented the
5709 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5710 Affected files lib/silcclient/command[_reply].c and
5711 lib/silcclient/client_notify.c. Implemented the KILL notify
5712 printing in the user inteface.
5714 * Fixed a lot silc_parse_nick memory leaks from the client
5715 library in the file lib/silcclient/command.c.
5717 * Changed the silc_server_send_notify_on_channels's `sender'
5718 argument from SilcSocketConnection to SilcClientEntry to
5719 check the sender as entry and not as connection object and not
5720 to send to the client provided as argument. The affected file
5721 is silcd/packet_send.[ch].
5723 * The notify packets that are destined directly to the client used
5724 to not to be processed by the server. Now changed that and the
5725 server processes all notify packets. After relaying the packet
5726 to the client the notify packet is processed in the server.
5728 * The silc_server_free_client_data now checks whether there is
5729 pending outgoing traffic for the client and purges the data to
5730 the network before removing the client entry.
5732 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5735 an client is killed from the SILC Network. Updated the protocol
5738 Added new function silc_server_send_notify_killed to the
5739 silcd/packet_send.[ch].
5741 * Added function silc_server_packet_relay_notify to relay notify
5742 packets that are destined directly to a client. In this case
5743 the server does not process the notify packets but merely relays
5744 it to the client. Affected file silcd/packet_send.[ch].
5746 Added also silc_server_packet_process_relay_notify to check
5747 whereto relay the notify. Affected file is
5748 silcd/packet_receive.[ch].
5750 * Implemented the KILL command to the server.
5754 * Added the backup schema desgined last fall to the protocol
5755 specs for everyone to see. The specification is in the
5756 *-spec-xx.txt draft and the packet type definitions for the
5757 backup routers is in *-pp-xx.txt draft. Thusly, added also
5758 new packet type SILC_PACKET_CELL_ROUTERS.
5760 * A big security problem in the implementation discovered. The
5761 signoff of an client did not cause new channel key generation
5762 which it of course should've done. The channel keys must be
5763 always re-generated when client leaves (or signoffs) the channel.
5764 The silc_server_remove_from_channels funtion now handles
5765 the channel key re-generation.
5767 * Added `sender' argument to the silc_server_send_notify_on_channels
5768 to not to send the client provided as argument. Affected file
5769 silcd/packet_send.[ch].
5771 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Implemented OPER and SILCOPER commands into the server and
5776 * Added silc_auth_verify and silc_auth_verify_data to verify
5777 the authentication directly from the authentication payload.
5778 It supports verifying both passphrase and public key based
5779 authentication. Affected file lib/silccore/silcauth.[ch].
5781 * Added `hash' field to the SilcIDListData structure. It is the
5782 hash negotiated in the SKE protocol. Affected file is
5785 * Slight redesigning of the SilcAuthPayload handling routines.
5786 Do not send SilcPKCS but SilcPublicKey as argument.
5788 * Implemented the public key authentication support to the
5789 serverconfig. The public key is loaded from the provided path
5790 and saved as authentication data to void * pointer. Thus,
5791 changed the unsigned char *auth_data to void *auth_data;
5793 * Fixed SHUTDOWN command to send the reply before the server
5794 is shutdown. :) Affected file silcd/command.c.
5796 * Fixed fatal bug in CONNECT command. The hostname was invalid
5797 memory and server crashed. Affected file silcd/command.c.
5799 * Fixed fatal bug in CLOSE command. The server_entry became
5800 invalid but was referenced later in the command. Affected file
5803 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Fixed fatal bug in failure packet handling. Server ignored
5806 the failure and thus crashed when it came.
5810 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5813 that the command may be executed only once in (about) 2 seconds.
5814 The old SILC_CF_LAG flag is same but allows command bursts up
5815 to five before limiting.
5817 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5818 server code. Various commands now includes the CF_LAG_STRICT
5819 flag to disallow any kind of miss-use of the command.
5821 * Fixed the silc_buffer_unformat to not to allocate any data
5822 if the length of the data is zero. It used to allocate the
5823 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5825 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Changed the format of AdminConnection configuration section
5828 in the server. Added username of the admin to the format.
5829 Affected files silcd/serverconfig.[ch].
5831 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5832 to return admin configuration data by host, username and/or
5835 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Implemented WHOWAS command to the server. Added the functions:
5839 silc_server_command_whowas_parse,
5840 silc_server_command_whowas_send_reply,
5841 silc_server_command_whowas_from_client and
5842 silc_server_command_whowas_from_server
5844 * Added <Client ID> argument to the WHOWAS command reply. Updated
5845 the protocol specs accordingly.
5847 * Implemented WHOWAS command and command_reply to the client
5850 Implemented the WHOWAS printing on the user interface.
5852 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Added new argument to the WHOWAS command reply, the real name.
5855 It is an optional argument. Updated the protocol specs.
5857 * Added SilcIDCacheDestructor callback that is registered when
5858 the SilcIDCache is allocated. The callback is called when
5859 an cache entry in the ID Cache expires, or is purged from the
5860 cache. Added into lib/silccore/idcache.[ch].
5862 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5863 to destruct the client entries when the cache entry expires.
5864 Other ID Cache's in server and in the client library ignores
5867 * If the ID Cache entry's `expire' field is zero then the entry
5868 never expires. Added boolean `expire' argument to the
5869 silc_idcache_add function in the lib/silccore/idcache.[ch].
5870 If it is TRUE the default expiry value is used.
5872 * Added silc_server_free_client_data_timeout that is registered
5873 when client disconnects. By default for 5 minutes we preserve
5874 the client entry for history - for WHOWAS command.
5876 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Added support to the server to enforce that commands are not
5879 executed more than once in 2 seconds. If server receives
5880 commands from client more frequently, timeout is registered
5881 to process the commands. Affected file silcd/command.c.
5882 Added new function silc_server_command_process_timeout.
5884 * Changed NICK_NOTIFY handling in client library to check that
5885 if the client's nickname was changed, so there is no need to
5886 resolve anything from the server.
5888 * Removed error printing from the WHOIS and IDENTIFY commands.
5889 If error occurs then it is ignored silently in the client library.
5890 The application, however, may map the received error to
5891 human readable error string. The application currently maps
5892 the NO_SUCH_NICKNAME error to string.
5894 * Made the command status message public to the application. Moved
5895 them from lib/silcclient/command_reply.c to
5896 lib/silcclient/command_reply.h. The application can map the
5897 received command status to the string with the
5898 silc_client_command_status_message function.
5900 * Added check to the server to check that client's ID is same
5901 as the Source ID in the packet the client sent. They must
5904 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Added dist-bzip hook to the Makefile.am to make bzip2
5907 compressed distributions.
5909 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Server now enforces the maximum length for the nickname and
5912 the channel as protocol specification dictates. 128 bytes for
5913 nickname and 256 bytes for channel name.
5915 * Moved the WHOIS printing to the application. The client libary
5916 does not print out the WHOIS information anymore, the application
5917 must do it. Renamed silc_client_command_reply_whois_print to
5918 the silc_client_command_reply_whois_save.
5920 The client's idle time is also sent to the application now, and
5921 the idle is shown on screen.
5923 * Added silc_client_command_reply_identify_save to save the
5924 received IDENTIFY entries.
5926 * Do not check for channel private keys in message sending and
5927 reception if the channel does not have the PRIVKEY mode set.
5928 Affected file lib/silclient/client_channel.c.
5930 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5933 just surfaced after chaning the JOIN procedure.
5935 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Added silc_client_get_clients_by_list to get client entries
5938 from Client ID list, that is returned for example by JOIN
5939 and USERS command replies. The application should use this
5940 function for example when JOIN command reply is received to
5941 resolve the clients already on the channel (library does not
5942 do that anymore as USERS command reply is not used in the JOIN
5943 procedure anymore). Affected files lib/silcclient/silcapi.h and
5944 lib/silcclient/idlist.c.
5946 * JOIN command reply and USERS command reply returns now SilcBuffer
5947 pointers instead of unsigned char pointers when returning
5948 the client list and mode list.
5950 * Added <Client ID> argument to the JOIN command reply, mainly
5951 for the server to identify for which client the command was
5952 originally sent. Updated protocol specs accordingly.
5954 * Added SilcDlist private_key pointer to the SilcChannelEntry
5955 in the client to support the channel private keys. Affected
5956 file is lib/silcclient/idlist.h.
5958 * Added SilcChannelPrivateKey argument to the function
5959 silc_client_send_channel_message so that application can choose
5960 to use specific private ke if it wants to. If it is not provided,
5961 the normal channel key is used, unless private keys are set.
5962 In this case the first (key that was added first) is used
5963 as the encryption key.
5965 * Implemented the support for channel private key handling.
5966 Implemented the following functions:
5968 silc_client_add_channel_private_key,
5969 silc_client_del_channel_private_keys,
5970 silc_client_del_channel_private_key,
5971 silc_client_list_channel_private_keys and
5972 silc_client_free_channel_private_keys
5974 Affected file lib/silcclient/client_channel.c.
5976 * Added the support for the private keys in the channel message
5977 sending and encryption and in the message reception and
5978 decryption. Affected funtions are
5979 silc_client_send_channel_message and silc_client_channel_message.
5981 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Added SKE's key verify callback to the client library's
5984 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5986 * Removed the statement that server (or router) must send USERS
5987 command reply when joining to the channel so that the client
5988 knows who are on the channel. Instead, the client list and
5989 client's mode list is now sent in the JOIN command reply to the
5990 client who joined channel. This is better solution.
5992 * Added function silc_server_get_users_on_channel and function
5993 silc_server_save_users_on_channel to the silcd/server.[ch].
5995 * Removed function silc_server_command_send_users from the
5998 * Do not show topic on the client library anymore. The topic is
5999 sent in the command reply notify to the application and the
6000 application must show the topic now.
6002 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Added client searching by nickname hash into the IDENTIFY and
6005 WHOIS commands in the server as they were clearly missing from
6006 them. Affected file is silcd/command.c.
6008 * Fixed a bug in private message receiving in the client library.
6009 The remote ID was freed and it wasn't supposed, now it is
6012 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Minor fix to the channel payload; allocate the data area, as it
6015 needs to be of specific length.
6017 * If the key agreement port is zero then the operating
6018 system will define the bound port. Affected files are
6019 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6021 * Added new function silc_channel_payload_decrypt into the file
6022 lib/silccore/silcchannel.[ch].
6024 * Moved the channel message etc, check from silc_packet_decrypt
6025 to applications. The library calls now a generic
6026 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6027 when the packet is either normal or special. This was done to
6028 allow more wide range of checking that was not allowed when
6029 the code was in library. Now applications can do virtually any
6030 checks to the packet and return to the library the decision how
6031 the packet should be processed. Affected files are
6032 lib/silccore/silcpacket.[ch].
6034 Added silc_server_packet_decrypt_check to the server and
6035 silc_client_packet_decrypt_check to the client library.
6037 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6038 to send with specified source and destination information.
6040 * Channel message delivery between routers was broken after the
6041 channel key distribution was fixed earlier. The channel key
6042 was used be to distributed to other routers as well which is not
6043 allowed by the protocol. Now this is fixed and channel keys
6044 really are cell specific and the channel message delivery between
6045 routers comply with the protocol specification.
6047 * Fixed various commands in server to check also the global list
6048 for the channel entry and not just the local list. The affected
6049 file silcd/command.c.
6051 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added assert()s to buffer formatting and unformatting routines
6054 to assert (if --enable-debug) when error occurs. Affected
6055 file: lib/silcutil/silcbuffmt.c.
6057 * Changed to auto-reconnect to check whether the remote host is
6058 router and register the re-connect timeout if it is. It used
6059 to check that whether we are normal server, but router must do
6060 auto-reconnect with another router as well. Affected file
6063 * Removed the [<key len>] option from CMODE command as the cipher
6064 name decides the key length, nowadays. See the defined ciphers
6065 from the protocol specification.
6067 * Added [<hmac>] option to the CMODE command to define the HMAC
6068 for the channel. Added SILC_CMODE_HMAC channel mode.
6070 * Added [<hmac>] option for the JOIN command so that user can
6071 select which HMAC is used to compute the MACs of the channel
6074 * Added Hmac field to the Channel Message Payload. The integrity
6075 of plaintext channel messages are now protected by computing
6076 MAC of the message and attaching the MAC to the payload. The
6077 MAC is encrypted. Now, it is clear that this causes some
6078 overhead to the size of the packet but rationale for this is that
6079 now the receiver can verify whether the channel message decrypted
6080 correctly and also when private keys are set for the channel the
6081 receiver can decrypt the packet with several keys and check from
6082 the MAC which key decrypted the message correctly.
6084 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6085 lib/silccrypt/silccipher.[ch].
6087 * Added silc_hash_len to return the digest length into the
6088 lib/silcrypt/silchash.[ch].
6090 * Rewrote parts of Silc Channel Payload interface in the
6091 lib/silccore/silcchannel.[ch]. The encode function now also
6092 encrypts the packet and parse function decrypts it.
6094 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Fixed a minor formatting bug in the SKE's key material processing.
6097 It actually might have processed the keys wrong way resulting
6100 * Redefined the mandatory HMAC algorithms and added new algorithms.
6101 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6102 and hmac-md5 truncated to 96 bits. The mandatory is now
6103 hmac-sha1-96. Rest are optional (including the one that used
6104 to be mandatory). Rationale for this is that the truncated HMAC
6105 length is sufficient from security point of view and can actually
6106 make the attack against the HMAC harder. Also, the truncated
6107 HMAC causes less overhead to the packets. See the RFC2104 for
6110 * Added new [hmac] configuration section. The SKE used to use
6111 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6112 is of course wrong. The official names that must be proposed in
6113 the SKE are the ones defined in the protocol specification
6114 (hmac-sha1-96 for example). The user can configure any hmac
6115 using any hash function configured in the [hash] section. At
6116 least, the mandatory must be configured.
6118 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6120 * Added HMAC list to the SKE proposal list. It has now both
6121 hash algorithm list and HMAC list. This makes the protocol
6122 incompatible with previous versions. The SKE now seems to work
6123 the way it is supposed to work, for the first time actually.
6125 * Defined plain Hash algorithms to the protocol specification.
6128 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Implemented support for key agreement packets into the server.
6131 Added functions silc_server_key_agreement and
6132 silc_server_send_key_agreement. Other than these functions,
6133 server has nothing to do with this packet.
6135 * Added support for private message key packets into the server.
6136 Added functions silc_server_private_message_key and
6137 silc_server_send_private_message_key.
6141 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6142 called in the protocol's final callback instead in the END
6143 protocol state. This makes a little more sense and in the same
6144 time in client we can use the same protocol routines for normal
6145 key exchange and to key agreement packet handling as well.
6147 * Added to both client's and server's KE protocol context the
6148 SilcSKEKeyMaterial pointer to save the key material. We will
6149 bring the key material to the protocol's final callback by doing
6150 this. The final callback must free the key material.
6152 * Added SKE's packet_send callback into client's KE protocol
6153 context so that the caller can choose what packet sending function
6154 is used. This way we can use different packet sending when
6155 doing normal SKE when doing key agreement packet handling (in
6156 the key agreement packet handling we do not want to encrypt
6159 * Implemented the responder side of the key agreement routines
6160 in the client. The client can now bind to specified port and
6161 accept incoming key negotiation. The key material is passed
6162 to the application after the protocol is over.
6164 * Implemented the processing of incoming Key Agreement packet
6165 in the client. Added function silc_client_key_agreement to
6168 * Implemented the intiator side of the key agreement routines
6169 in the client. The client can now initiate key agreement with
6170 another remote client. The key material is passed to the
6171 application after the protocol is over.
6173 * Created client_keyagr.c to include all the key agreement
6176 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6177 SILC_TASK_CALLBACK except that it is not static.
6179 * Created client_notify.c and moved the Notify packet handling
6180 from the client.[ch] into that file.
6182 * Created client_prvmsg.c and moved all private message and
6183 private message key routines from the client.[ch] into that file.
6185 * Create client_channel.c and moved all channel message and
6186 channel private key routines from the client.[ch] into that file.
6188 * Changed silc_client_get_client_by_id_resolve to resolve with
6189 WHOIS command instead of IDENTIFY command, in the file
6190 lib/silclient/idlist.c.
6192 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Implemented the SKE's responder side to the Client library.
6196 * When FAILURE is received to the protocol do not trust it
6197 blindly. Register a timeout to wait whether the remote closes
6198 the connection as it should do it, only after that process the
6199 actual failure. This was changed to both client and server.
6201 * Added client_internal.h to include some of the structures
6202 there instead of client.h in lib/silcclient/.
6204 * Added function silc_task_unregister_by_callback to unregister
6205 timeouts by the callback function.
6207 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Some "Incomplete WHOIS info" errors has been appearing on the
6210 log files. Took away the entry->userinfo check from WHOIS
6211 reply sending. The entry->userinfo is now " " if client did not
6212 provide one. I thought this was fixed earlier but something
6213 is wrong still. Let's see if the error still appears.
6215 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Fixed a minor bug in the login when the channel key is
6218 re-generated in the server. It used to generate the key in
6219 wrong order and thus caused problems in the channel traffic.
6221 * Fixed a minor bug in channel key distsribution after
6222 KICK command. The key was not sent to the router even though
6225 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added silc_ske_process_key_material_data as generic routine
6228 to process any key material as the SILC protocol dictates. The
6229 function is used by the actual SKE library but can be used by
6230 applications as well. This relates to the private message keys
6231 and the channel private keys since they must be processed the
6232 same way the normal SILC session keys. The protocol dictates
6233 this. Affected files: lib/silcske/silcske.[ch].
6235 Added also silc_ske_free_key_material to free the
6236 SilcSKEKeyMaterial structure.
6238 * Defined silc_cipher_set_key function to set the key for
6239 cipher without using the object's method function. The affected
6240 files: lib/silccrypt/silccipher.[ch].
6242 * Implemented silc silc_client_add_private_message_key,
6243 silc_client_add_private_message_key_ske,
6244 silc_client_del_private_message_key,
6245 silc_client_list_private_message_keys and
6246 silc_client_free_private_message_keys functions in the
6249 Added functions silc_client_send_private_message_key to send
6250 the Private Message Key payload and silc_client_private_message_key
6251 to handle incoming Private Message Key payload.
6253 * Added Cipher field to the Private Message Key payload to set
6254 the cipher to be used. If ignored, the default cipher defined
6255 in the SILC protocol (aes-256-cbc) is used.
6257 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Removed lib/silcclient/ops.h file.
6261 Redefined parts of the SILC Client Library API. Created new
6262 file silcapi.h that deprecates the ops.h file and defines the
6263 published Client Library API. Defined also private message key
6264 API and channel private key API into the file.
6266 This is the file that the application must include from the
6267 SILC Client Library. Other files need not be included by
6268 the application anymore.
6270 * Added new key_agreement client operation callback and also
6271 defined the Key Agreement library API for the application.
6273 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6276 is used by clients to request key negotiation between another
6277 client in the SILC network. If the negotiation is started it
6278 is performed using the SKE protocol. The result of the
6279 negotiation, the secret key material, can be used for example
6280 as private message key.
6282 Implemented the Key Agreement payload into the files
6283 lib/silccore/silauth.[ch].
6285 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Redefined ciphers for the SILC protocol. Added some new ciphers
6288 and defined the key lengths for the algorithms. Changed the
6289 code accordingly. The default key length is now 256 bits.
6291 * Fixed SKE key distribution function silc_ske_process_key_material
6292 when the key length is more than 128 bits. The default key
6293 length in SILC is now 256 bits.
6295 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6296 to indicate unsupported algorithm.
6298 * Renamed rijndael.c to aes.c and all functions as well.
6300 * Fixed a long standing channel key setting bug in client library.
6301 Weird that it has never surfaced before.
6303 * Fixed bug in channel deletion. If the entire channel is removed
6304 then it must also delete the references of the channel entry
6305 from the client's channel list as the client's channel entry and
6306 the channel's client entry share same memory.
6308 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Implemented CONNECT and SHUTDOWN commands in the client.
6312 * Implemented CLOSE command to the client.
6314 * Added the function silc_idlist_find_server_by_name into the
6315 files silcd/idlist.[ch].
6317 Added the function silc_idlist_find_server_by_conn into the
6318 files silcd/idlist.[ch].
6320 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * DIE command was renamed to SHUTDOWN. Updated the both code
6325 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6326 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6328 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6331 * Added function silc_server_create_connection function to create
6332 connection to remote router. My server implementation actually
6333 does not allow router to connect to normal server (it expects
6334 that normal server always initiates the connection to the router)
6335 so the CONNECT command is only good for connecting to another
6338 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6341 or some other client was kicked from the channel.
6343 Implemented the handling of the notify type to both client
6346 Implemented silc_server_send_notify_kicked to send the KICKED
6347 notify. It is used to send it to the server's primary router.
6349 * Implemented the KICK command into server and client.
6351 * Added `query' argument to the silc_idlist_get_client function
6352 to indicate whether to query the client from server or not if
6355 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6356 to indicate that the client is not channel founder.
6360 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Removed the rng context from SilcPacketContext structure and
6363 changed that the packet routine uses the Global RNG API.
6365 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Added support for quit message that client can "leave" on the
6368 channel when it quits the SILC. It is ditributed inside the
6369 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6371 Added silc_server_free_client_data that will take the
6372 signoff message as argument.
6374 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6376 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6378 * Updated parts of the protocol specification to keep it up
6381 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6384 payloads in one packet.
6386 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6387 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6388 use now the new List flag.
6390 * Also deprecated the following packet types: REPLACE_ID,
6391 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6393 * Added list support for Notify packet in server.
6395 * Added silc_server_send_notify_channel_change to send the
6396 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6397 the silc_server_send_replace_id.
6399 * Added silc_server_send_notify_nick_change to send the
6400 NICK_CHANGE notify type. Deprecates the function
6401 silc_server_send_replace_id.
6403 * Added silc_server_send_notify_join to send the JOIN notify type.
6404 Deprecates the function silc_server_send_new_channel_user.
6406 * Added silc_server_send_notify_leave to send LEAVE notify type.
6407 Deprecates the function silc_server_send_remove_channel_user.
6409 * Added silc_server_send_notify_cmode and
6410 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6411 types. Deprecates the silc_server_send_set_mode function.
6413 * Added SERVER_SIGNOFF notify type to indicate that server has
6414 quit. This means that all clients on the channel from that
6415 server will drop. This can be also used when netsplit happens.
6417 Deprecated REMOVE_ID packet type since it is not needed anymore
6420 Added silc_server_send_notify_server_signoff to send the
6421 SERVER_SIGNOFF notify type. Deprecates the function
6422 silc_server_send_remove_id.
6424 Added also silc_server_send_notify_signoff to send the
6425 SIGNOFF notify type.
6427 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6428 SILC protocol from this day on. Changed the protocol
6429 specification as well.
6431 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6432 notify type. It is used between routers to notify about
6433 topic changes on a channel.
6435 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6438 * Partly updated the protocol specification to comply with the
6439 changes now made. It is still though a bit outdated.
6441 * The JOIN notify type now takes one extra argument <Channel ID>.
6442 The packet used to be destined to the channel but now the
6443 JOIN type may be sent as list thus it is impossible to
6444 destine it to any specific channel. By adding this argument
6445 it is again possible.
6447 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6449 * Added CREDITS file. The CHANGES and CREDITS file will appear
6450 in the distribution as well.
6452 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6455 types in the server's silcd/packet_receive.c.
6457 * Implemented CMODE and CUMODE to work in router environment.
6459 * Fixed minor encoding and decoding buglet from the
6460 lib/silccore/silcmode.c.
6462 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6465 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6467 * Changed all SilcConfigServer* and silc_config_server* to
6468 SilcServerConfig* and silc_server_config*, respectively.
6471 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Associated the ID (client or server ID) to the Authentication
6474 Payload to avoid any possibility of forging. Updated the
6475 protocol specification and the code accordingly.
6477 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * The RSA key length is now save to the RsaKey context in the
6480 key generation process in lib/silccrypt/rsa.c. The key length
6481 is now used to figure out the maximum size of the block allowed
6482 to be encrypted/signed.
6484 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6485 is equivalent to the silc_mp_mp2bin but does not allocate any
6488 * Changed silc_mp_mp2bin API to take length argument. If it is
6489 non-zero then the buffer is allocated that large. If zero, then
6490 the size is approximated using silc_mp_sizeinbase, which however
6493 * Created Global RNG API which is global RNG that application can
6494 initialize. After initializing, any routine anywhere in the
6495 code (including library) can use RNG without allocating a new
6496 RNG object. This was done to allow this sort of use of the
6497 RNG in code that has no chance to allocate RNG object. All
6498 applications currently allocate this and many routines in the
6499 library use this. Affected file lib/silccrypt/silcrng.[ch].
6501 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6502 it to use the Global RNG API.
6504 * Defined Authentication Payload into protocol specification that
6505 is used during SILC session to authenticate entities. It is
6506 used for example by client to authenticate itself to the server
6507 to obtain server operator privileges.
6509 Implemented this payload into the lib/silccore/silcauth.[ch].
6510 Implemented also routines for public key based authentication
6511 as the new protocol specification dictates.
6513 Moved definitions of different authentication methods from
6514 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6516 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6517 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6518 silc_pkcs_verify_with_hash functions into the file
6519 lib/silccrypt/silcpkcs.[ch].
6521 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * The client entry's userinfo pointer must be always valid.
6524 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6525 will fail since it requires the userinfo. Now, the userinfo
6526 is allocated as "" if actual userinfo does not exist. Actually,
6527 it must exist and it is totally Ok to drop client connections
6528 that does not announce the userinfo. However, we will make
6529 this workaround for now.
6531 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6532 to return the remote port by socket.
6534 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6537 SILC_SERVER_PENDING_EXEC and added an new macro
6538 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6539 data or when error occurs while processing the pending command.
6541 Added new argument `destructor' into silc_server_command_pending
6542 and to the SilcServerCommandPending object. This destructor is
6543 now called after calling the pending callback or if error occurs
6544 immediately. If error occurs the actual pending callback won't
6545 be called at all - only the destructor. The destructor may be
6546 NULL if destructor is not needed.
6548 All this applies for client library code as well. Similar
6549 changes were made there as well for the pending commands.
6551 In the client, the application must now allocate the
6552 SilcClientCommandContext with the silc_client_command_alloc
6555 * Added reference counter to the SilcServerCommandContext. Added
6556 function silc_server_command_alloc and silc_server_command_dup
6559 Same type of functions added to the client library for the same
6562 * Removed the cmd_ident from IDListData away since it is now
6563 global for all connections. It is the command identifier used
6564 in command sending and with pending commands. The affected file
6567 * Added reference counter to the SilcSocketConnection objecet to
6568 indicate the usage count of the object. The object won't be
6569 freed untill the reference counter hits zero. Currently only
6570 server uses this, and client ignores it. The client must be
6571 set to use this too later. The affected files are
6572 lib/silccore/silcsockconn.[ch]. Added also the function
6573 silc_socket_dup to increase the reference counter.
6575 This was mainly added because it is possible that the socket
6576 is removed underneath of pending command or other async
6577 operation. Now it won't be free'd and proper DISCONNECTING
6578 flags, etc. can be set to avoid sending data to connection that
6579 is not valid anymore.
6581 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6582 the connection. After that it sets SILC_SET_DISCONNECTED.
6583 It is, however, possible that the socket data is not still freed.
6584 The silc_server_packet_process now checks that data is not
6585 read or written to connection that is DISCONNECTED. The socket
6586 get's freed when the reference counter hits zero.
6588 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Changed the client operation API: channel_message operation's
6591 `sender' is now the client entry of the sender, not the nickname
6592 and the `channel' is the channel entry, not the channel name.
6594 In the private_message operation the `sender' is now also the
6595 client entry of the sender not the nickname.
6597 Affected file is lib/silcclient/ops.h and all applications
6598 using the client operations.
6600 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Moved the calling of ops->connect() from connect_to_server_final
6603 into receive_new_id functin since that is the point when the
6604 client is actually allowed to send traffic to network. The
6605 affected file is lib/silcclient/client.c.
6607 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6610 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6611 (if needs broadcasting) instead of broadcasting the packets one
6612 by one which would make a burst in the network traffic.
6614 * Added `broadcast' argument to the functions in silcd/server.[ch]
6615 silc_server_create_new_channel[_with_id] to indicate whether
6616 to send New Channel packet to primary router.
6618 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Added new function into the silcd/server.[ch] files:
6621 silc_server_create_new_channel_with_id to create new channel with
6622 already existing Channel ID.
6624 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6625 lib/silccore/silcpacket.h. This packet is used t send list of
6626 Set Mode payloads inside one packet. Server uses this to set
6627 the modes for the channels and clients on those channels, that it
6628 announced to the router when it connected to it. The protocol
6629 specification has been updated accordingly.
6631 * The silc_server_new_channel did not handle the packet coming
6632 from normal server as it normally does not send that. However,
6633 when it announces its channels it does send it. Implemented
6634 the support for that.
6636 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6637 into the file lib/silccore/id.h.
6639 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Fixed memory leaks in the functions silc_idlist_del_client,
6642 silc_idlist_del_channel and silc_idlist_del_server in the file
6643 silcd/idlist.c. All of those leaked like a sieve.
6645 * Fixed some small memory leaks in the client's function
6646 silc_client_notify_by_server.
6648 * Added functions into silcd/server.c: silc_server_announce_clients,
6649 silc_server_announce_channels and silc_server_announce_server.
6650 These functions are used by normal and router server to announce
6651 to its primary router about clients, channels and servers (when
6652 router) that we own. This is done after we've connected to the
6655 These functions effectively implements the following packet types:
6656 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6657 and SILC_PACKET_NEW_ID_LIST.
6659 * Added new functions into the silcd/packet_receive.[ch]:
6660 silc_server_new_id_list, silc_server_new_channel_list and
6661 silc_server_new_channel_user_list to handle the incoming
6662 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6664 * Added support of changing Channel ID in the function
6665 silc_server_replace_id. If the server that announces a channel
6666 to the router already exists in the router (with same name but
6667 with different Channel ID), router is responsible to send
6668 Replace ID packet to the server and force the server to change
6669 the Channel ID to the one router has.
6671 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6672 client that the Channel ID has been changed by the router. The
6673 normal server sends this to the client. Client must start using
6674 the new Channel ID as the channel's ID.
6676 Implemented handling of this new type into lib/silcclient/client.c
6677 into the function silc_client_notify_by_server.
6679 * Added new function silc_idlist_replace_channel_id into the files
6680 silcd/idlist.[ch] to replace the Channel ID.
6682 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Call silc_server_command_identify_check always when processing
6685 the IDENTIFY command in silcd/command.c
6687 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6690 send keepalive packets. The packet can be sent by clients,
6691 servers and routers.
6693 Added function silc_socket_set_heartbeat into the file
6694 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6695 If not set, the heartbeat is not performed. The actual
6696 heartbeat is implemented in the low level socket connection
6697 library. However, application is responsible of actually
6700 Added silc_server_send_heartbeat to send the actual heartbeat
6701 packet into silcd/packet_send.[ch]. Server now performs
6702 keepalive with all connections.
6704 * Added silc_task_get_first function into lib/silcutil/silctask.c
6705 to return the timeout task with shortest timeout. There was a bug
6706 in task unregistration that caused problems. TODO has been
6707 updated to include that task system must be rewritten.
6709 * The client library will now resolve the client information when
6710 receiving JOIN notify from server for client that we know but
6711 have incomplete information.
6713 * Rewrote parts of silc_server_remove_from_channels and
6714 silc_server_remove_from_one_channel as they did not remove the
6715 channel in some circumstances even though they should've.
6717 * Encryption problem encountered in server:
6719 The LEAVE command used to send the Channel Key packet to the
6720 router immediately after generating it. However, the code
6721 had earlier sent Remove Channel user packet but not immediately,
6722 ie. it was put to queue. The order of packets in the router
6723 was that Channel Key packet was first and Remove Channel User
6724 packet was second, even though they were encrypted in the
6725 reverse order. For this reason, MAC check failed. Now, this
6726 is fixed by not sending the Channel Key packet immediately but
6727 putting it to queue. However, this is more fundamental problem:
6728 packets that are in queue should actually not be encrypted
6729 because packets that are sent immediately gets encrypted
6730 actually with wrong IV (and thus MAC check fails). So, packets
6731 that are in queue should be encrypted when they are sent to
6732 the wire and not when they put to the queue.
6734 However, the problem is that the current system has not been
6735 designed to work that way. Instead, the packet is encrypted
6736 as soon as possible and left to the queue. The queue is then
6737 just purged into wire. There won't be any fixes for this
6738 any time soon. So, the current semantic for packet sending
6741 o If you send packet to remote host and do not force the send
6742 (the packet will be in queue) then all subsequent packets to the
6743 same remote host must also be put to the queue. Only after the
6744 queue has been purged is it safe again to force the packet
6747 o If you send all packets immediately then it safe to send
6748 any of subsequent packets through the queue, however, after
6749 the first packet is put to queue then any subsequent packets
6750 must also be put to the queue.
6752 Follow these rules and everything works fine.
6754 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added new function silc_server_remove_clients_by_server to
6757 remove all client entries from ID list when the server connection
6758 is lost. In this case it is also important to invalidate all
6759 client entires as they hold the invalid server entry. This
6760 fixes fatal bug when server has lost connection and will reconnect
6763 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Made some sanity checks to silc_server_daemonise like to check
6766 whether the requested user and group actually exists.
6768 * Added sanity check to SKE's silc_ske_responder_finish to check
6769 that the public and private key actually is valid.
6771 * Invalidate the client's nickname when receiving Replace ID
6772 packet and the Client ID is being replaced. This means that the
6773 server will query the nickname if someone needs it (client)
6776 * Sort the ID Cache in client library when the ID Cache data
6777 has changed (needs sorting).
6779 * Do not allow for SILC client to create several connections to
6780 several servers. The client does not support windows right now
6781 and generating multiple connections causes weird behaviour.
6783 Irssi-silc client does support windows and can handle several
6784 connections without problems, see: www.irssi.org and SILC plugin.
6786 * Fixed some places where client was added to the IDList. The
6787 rule of thumb is following (in order to get everything right):
6788 If the client is directly connected local client then the
6789 `connection' argument must be set and `router' argument must be
6790 NULL to silc_idlist_add_client function. If the client is not
6791 directly connected client then the `router' argument must
6792 bet set and the `connection' argument must be NULL to the
6793 silc_idlist_add_client function.
6795 * The funtion silc_server_packet_send_local_channel actually did
6796 not check whether the client was locally connected or not. It
6797 does that now. Fixed a bug related to LEAVE command.
6799 * Fixed Remove Channel User payload parsing bug in server's
6800 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6802 * The server's silc_server_save_channel_key now checks also the
6803 global ID list for the channel as it might not be in the local
6804 list. Fixed a bug related to LEAVE command.
6806 * Is this the end of the [<unknown>] buglet that has been lurking
6807 around for a long time? A little for loop fix in server's
6808 silc_server_command_whois_parse that is used by both IDENTIFY
6809 and WHOIS command. At least, this was a clear bug and a cause
6810 of one type of [<unknown>] buglet.
6812 * WHOIS and IDENTIFY commands call the function
6813 silc_server_command_[whois/identify]_check function even if
6814 we are not router server.
6816 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Added --with-gmp configuration option. If set the GMP
6819 is always compiled in the SILC source tree. If not set then
6820 it is checked whether the system has the GMP3 installed. If
6821 it has then the GMP won't be compiled (the system's headers
6822 and library is used), if it doesn't have it then the GMP is
6823 compiled in the SILC source tree.
6825 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Changed RSA private exponent generation to what PKCS #1
6828 suggests. We try to find the smallest possible d by doing
6829 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6830 not security fix but optimization.
6832 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Added new config entry [Identity] to fork the server and run
6835 it as specific user and group. A patch from Bostik.
6837 * Imported Dotconf configuration library into lib/dotconf.
6838 This will be used to create the SILC configuration files later.
6839 It will appear in the distsribution after this commit.
6841 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * A big code auditing weekend happening. Auditing code for
6844 obvious mistakes, bugs and errors. Also, removing any code
6847 Removed files for being obsolete:
6849 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6850 inline in the file lib/silcutil/silcbuffer.h)
6852 o lib/silcutil/silcbufutil.c (the header has inline versions)
6854 Changed code to fix possible error conditions:
6856 o The buffer formatting routines now check that the destination
6857 buffer really has enough space to add the data. This applies for
6858 both buffer formatting and unformatting
6859 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6860 unformatting was changed to accomodate following rules:
6861 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6862 sent to the function while XXX_*STRING will not allocate or copy
6863 the data into the buffer. Instead it sets the pointer from the
6864 buffer into the pointer sent as argument (XXX_*STRING used to
6865 require that the pointer must be allocated already). This change
6866 makes this whole thing a bit more consistent and more optimized
6867 (note that the data returned in the unformatting with XXX_*STRING
6868 must not be freed now). The routines return now -1 on error.
6870 o Tried to find all code that use buffer_format and buffer_unformat
6871 and added return value checking to prevent formatting and
6872 especially unformatting errors and possible subsequent fatal
6875 o Changed ske->x and ske->KEY to mallocated pointers in
6876 lib/silcske/silcske.h. Fixed possible data and memory leak.
6878 o Added return value checking to all *_parse* functions. Fixed
6879 many memory leaks as well.
6881 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6882 so that buffer overflows would not happen. All code now also
6883 checks the return value as it can fail.
6885 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Added reconnection support to server if the normal server looses
6888 its connection to the router (for example if router is rebooted).
6889 The server performs normal reconnection strategy implemented
6890 to the server. Affected file silcd/server.c.
6892 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Added new packet type SILC_PACKET_SET_MODE that is used to
6895 distribute the information about changed modes (for clients,
6896 channels and clients channel modes) to all routers in the
6897 network. Updated the protocol specification accordingly.
6899 Added functions into silcd/packet_send.c and
6900 silcd/packet_receive.c: silc_server_send_set_mode,
6901 silc_server_set_mode.
6903 Added new files silcmode.[ch] into lib/silccore that implements
6904 the encoding and decoding of Set Mode Payload. Added new type
6905 SilcSetModePayload. Moved the definitions of different modes
6906 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6908 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Oops, a little mistake in server's connection authentication
6911 protocol. The protocol is not ended with FAILURE but with
6912 SUCCESS if the authentication is Ok. :) Affected file is
6915 * Implemented NICK_CHANGE notify handling in server in the file
6916 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6917 the local clients on the channel. After the changing nickname
6918 in router environment snhould work and the [<unknown>] nickname
6919 should appear no more.
6921 The silc_server_replace_id function that receives the Replace ID
6922 payload now sends the NICK_CHANGE notify type also in the file
6923 silcd/packet_receive.c
6925 * Changed WHOIS and IDENTIFY command to support the maximum amount
6926 of arguments defined in protocol specs (3328 arguments). This
6927 fixed a bug that caused problems when there were more than three
6930 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6932 * Added extra parameter, command identifier, to the
6933 silc_client_send_command so that explicit command identifier
6936 Changed that ID list routines uses specific command identifier
6937 when sending WHOIS/IDENTIFY requests to the server so that they
6938 can be identified when the reply comes back.
6940 Affected files lib/silcclient/command.[ch],
6941 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6943 * Added `sender' argument to silc_server_packet_send_to_channel
6944 to indicaet the sender who originally sent the packet to us
6945 that we are now re-sending. Ignored if NULL. Affected file
6946 silcd/packet_send.[ch].
6948 * Added some server statistics support in silcd/server_internal.h
6949 SilcServerStatistics structure and around the server code. Also
6950 send some nice statistics information when client is connecting
6953 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Fixed channel ID decoding in server's JOIN command reply in
6956 silcd/command_reply.c
6958 * Fixed braodcasting of replace ID payload to not to send it if
6959 we are standalone server in silcd/packet_receive.c.
6961 * Fixed all channel message sending routines to not to send
6962 packets to clients that has router set, since they are routed
6963 separately in the same function earlier. Affects file
6964 silcd/packet_send.c and all channel packet sending functions.
6966 * In USERS reply, res_argv[i] are not allocated, the table
6967 is allocated. Thus changed that free the table, not its
6970 * In server's whois_check and identify_check if the client is
6971 locally connected do not send any WHOIS commands - they are not
6974 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Fixed some minor bugs in client when sending WHOIS command. The
6977 arguments was in wrong order.
6979 * Removed statis function add_to_channel from server in
6980 silcd/command.c that was previously used with the joining but
6983 * Tested USERS command in router environment successfully with two
6984 routers, two servers and two clients.
6986 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Reorganized the USERS command and command reply in client library
6989 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6990 When the command is given by user we register a pending command
6991 callback that will reprocess the command after the reply has been
6992 received from the server. When reprocessing the packet we then
6993 display the information. Thus, the USERS information is displayed
6994 now in the command callback instead of in the command reply
6995 callback. The processing of the command is same as previously
6996 when server has sent the command reply in the JOINing process.
6998 * Added to USERS command in silcd/command_reply.c to join the client,
6999 we didn't use to know about, to the channel after we've created
7000 a client entry for it. Also, for clienet we did know already still
7001 check whether it is on the channel or not and add it if not.
7003 * Removed silc_server_command_join_notify as the function and its
7006 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7008 * Changed the client's pending command handling to the same as the
7009 server's pending command handling. It is also now possible to
7010 execute command reply functions from other command reply
7011 function as the function callbacks for commands and command
7012 replies are one and same. The pending commands are not static
7013 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7014 in client connection context. Thus, pending commands are server
7015 connection specific as it is convenient.
7017 Changed the function silc_client_command_pending and
7018 silc_client_command_pending_del and added new function
7019 silc_client_command_pending_check. Removed the
7020 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7023 * Added cmd_ident, current command identifier, to the client
7024 connection context in lib/silcclient/client.h to keep track on
7025 command identifiers used in command sending. Client's command reply
7026 function handling now supports the mandatory command identifiers.
7028 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7029 funtions in client to fully support pending command callbacks.
7031 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7032 as one of the arguments to the application in the command reply
7035 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7036 before first releasing SILC but came back. Now it is removed again
7037 and should come back nomore. The FORWARDED flag was used only
7038 by the JOINing procedure by forwarding the command packet to router.
7039 Now, the JOINing procedure has been changed to more generic (due
7040 to various router environment issues) and FORWARDED is not needed
7041 anymore for anything. The protocol specification is yet to be
7044 Now, removed silc_server_packet_forward from server and the flag
7045 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7047 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Renamed NAMES command to USERS command. The NAMES was named that
7050 due to historical reasons. Now it is renamed. Also, rewrote
7051 parts of the USERS command. The nickname list is not sent anymore
7052 by the server. Only Client ID and mode lists are sent in the USERS
7053 command. Changed this also to the protocol specification.
7055 The client now resolves the names and stuff after it receives
7056 the USERS list from the server when joining to the channel.
7058 * WHOIS and IDENTIFY commands has been changed to support multiple
7059 Client ID's per command. One can now search for multiple users
7060 in the network by sending only one WHOIS or IDENTIFY command.
7061 Changed the code and the protocol specifications.
7063 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7064 uses silc_server_command_whois_parse to parse the request. */
7066 * If normal server, do not parse the WHOIS and IDENTIFY requests
7067 before sending it to the router. Saves some time.
7069 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Fixed JOIN command on client library. Wrong number of arguments
7072 used to crash the client.
7074 * Added silc_server_channel_has_global function to check whether
7075 channel has global users or not.
7077 * Added silc_server_channel_has_local function to check whether channel
7078 has locally connected clients on the channel.
7080 * The silc_server_remove_from_one_channel now checks whether the
7081 channel has global users or not after given client was removed from
7082 the channel. It also checks whether the channel has local clients
7083 on the channel anymore. If it does not have then the channel entry
7084 is removed as it is not needed anymore.
7086 * The silc_server_notify now checks on JOIN notify whether the joining
7087 client is one of locally connected or global. If it is global then
7088 the channel has now global users on the channel and that is marked
7089 to the channel entry. Also, it now saves the global client to
7090 global list who is joining and JOINs it to the channel. This is
7091 for normal server, that is.
7093 Changed silc_server_send_notify_on_channel,
7094 silc_server_packet_relay_to_channel and
7095 silc_server_packet_send_to_channel check if we are normal server
7096 and client has router set (ie. global client) do not send the
7097 message to that client, as it is already routed to our router.
7099 * Implemented LEAVE notify type handling in silc_server_notify
7102 * Tested LEAVE command in router environment successfully. Tested
7103 with two routers, two servers and two clients.
7107 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7109 * Implemented SIGNOFF notify type handling in silc_server_notify
7112 * silc_server_remove_id now removes the client entry from all channels
7113 it has joined and thusly sends SIGNOFF notify type.
7115 * Rewrote the NAMES list generation in server by removing two excess
7116 loops. The lists are created now inside one loop.
7118 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * silc_server_remove_channel_user checks now also global list
7121 for channel and client.
7123 * silc_server_new_channel_user checks now both local and global
7124 list for channel and client. Fixed a bug in client id decoding.
7125 Used to decode wrong buffer.
7127 * silc_server_channel_message checks now both local and global
7128 list for channel entry.
7130 * Tested channel joining (hence JOIN) in router environment
7131 successfully. Tested with two routers, two servers and two
7134 * Tested channel message sending in router environment successfully.
7136 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Added silc_server_save_channel_key into server.[ch] to save the
7139 received channel key in Channel Key payload processing. It is
7140 also used in JOIN command reply handling.
7142 Equivalent function silc_client_save_channel_key added into
7143 client.[ch] into client library.
7145 * Changed JOIN command reply to send information whether the channel
7146 was created or not (is existing already) and the channel key
7147 payload. Changed protocol specs accordingly.
7149 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7150 the request was sent by ID and not by nickname. Crashed on
7153 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7156 now correctly save the received data.
7158 * silc_server_free_sock_user_data now notifies routers in the
7159 network about entities leaving the network.
7161 At the same time implemented functions silc_server_remove_id
7162 and silc_server_send_remove_id to receive and send REMOVE_ID
7163 packets. The packet is used to notify routers in the network
7164 about leaving entities. The ID removed will become invalid in
7167 * Added function silc_idlist_del_server into server. Removes and
7168 free's server entry from ID list.
7170 * silc_server_private_message function now checks, if we are router,
7171 that the destination ID really is valid ID, naturally.
7173 * In router when NEW_ID packet is received (for new client) the
7174 hash of the Client ID is saved in the ID Cache but the
7175 client->nickname is set to NULL, instead of putting the hash
7178 IDENTIFY command now also checks that client->nickname must be
7179 valid. If it is not if will request the data from the server who
7180 owns the client. Added new function
7181 silc_server_command_identify_check.
7183 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7184 to set the command to already allocated Command Payload.
7186 * Tested private message sending in router environment with two
7187 routers, two servers and two clients. Fixed minor bugs and now
7190 * Fixed segfault from client's NAMES command. Used to crash if
7193 * Forwarded packets must not be routed even if it is not destined
7194 to the receiver. Changed server code comply with this.
7196 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7198 * Added `require_reverse_mapping' boolean value to ServerParams
7199 structure. If TRUE (not default) the server will require that
7200 the connecting host has fully qualified domain name.
7202 If the reverse mapping is not required and hostname could not be
7203 found the IP address is used as hostname.
7205 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Implemented version string checking to both client and server.
7208 The check is incomplete currently due to the abnormal version
7209 strings used in development version of SILC.
7211 * Changed all command functions in server to use the new
7214 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Changed char *data to unsigned char *data in ID Cache system to
7217 support binary data as ID Cache data. Changed code to support
7218 binary data in lib/silccore/idcache.c.
7220 * Renamed silc_server_packet_relay_command_reply to
7221 silc_server_command_reply as it is normal packet receiving
7222 function. Rewrote the function to accept command replys for
7223 servers and not only for clients.
7225 * Mark remote router always as registered server if we are connecting
7226 to it. Otherwise, commands sent by the router to us are ignored.
7228 * All ID List find routines now returns the ID Cache Entry pointer
7229 as well if requested.
7231 * WHOIS command works now in router environment, tested with two
7232 routers, two servers and two clients.
7234 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7235 in router environment (as it is almost equivalent to WHOIS) but
7236 hasn't been tested thoroughly. Added new functions:
7238 silc_server_command_identify_parse
7239 silc_server_command_identify_send_reply
7240 silc_server_command_identify_from_client
7241 silc_server_command_identify_from_server
7243 * Disabled route cache adding because adding two different ID's with
7244 same IP replaces the old cache entry thus giving wrong route.
7245 The entry->router->connection is always the fastest route anyway
7246 so route cache may not be needed. Of course, new routes maybe
7247 established after receiving the ID when the entry->router->connection
7248 might not be anymore the most optimal.
7250 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7252 * Add route cache for received ID for fast routing.
7254 * Added silc_server_packet_route to route received packet on router
7255 that is not destined to us.
7257 * Renamed silc_server_get_route to silc_server_route_get.
7259 * Added id_string and id_string_len fields into SilcServer to
7260 include encoded ServerID for fast comparing without excess
7261 encoding of the ID's.
7263 * Cleaned up WHOIS command on server side. Added following static
7266 silc_server_command_whois_parse
7267 silc_server_command_whois_check
7268 silc_server_command_whois_send_reply
7269 silc_server_command_whois_from_client
7270 silc_server_command_whois_from_server
7272 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7273 arguments in command replies. All command functions should be
7274 updated to use this macro.
7276 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Minor typo fixes on command reply handling on server.
7280 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7282 * Added silc_server_command_add_to_channel internal routine to add
7283 the client to the channel after router has created the channel and
7284 sent command reply to the server.
7286 * Added generic silc_server_send_command to send any command from
7289 * Use static buffer with ID rendering instead of duplicating data.
7291 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7293 * Fixed a channel user mode bug when joining to a channel server gave
7294 everybody channel founder rights, oops.
7296 * We mark ourselves as the router of the incoming server connection
7297 if we are router ourselves. This way we can check in some packet
7298 sending functions whether it is locally connected server. For
7299 incoming router connections we put NULL.
7301 * For router sending packets locally means now always sending the
7302 packet cell wide; to local clients and local servers. For normal
7303 server sending packet locally means sending it to only local
7306 * Fixed the JOIN command to really work in router environment. If the
7307 channel is created it is always created by the router. Router is
7308 also responsible of making the initial joining to the channel,
7309 sending JOIN notify to the sending server and distributing
7310 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7311 does not exist server doesn't do anything else but forward the
7312 command to the router which performs everything.
7314 * Added silc_server_send_channel_key function to send the Channel Key
7317 * Added silc_server_create_channel_key to create new channel key. The
7318 channel key is now re-generated everytime someone joins or leaves
7319 a channel, as protocol dictates. Note: channel->key_len is the
7322 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7324 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7325 packet_receive.[ch] to separate packet sending and receiving
7326 routines. The server.[ch] now includes everything else including
7327 actual packet processing (writing and reading data) and other
7330 Renamed silc_server_private_message_send_internal to
7331 silc_server_send_private_message. The routine is still though
7332 used only to relay private messages as server does not send
7333 private messages itself.
7335 Renamed silc_server_new_channel to silc_server_create_new_channel
7336 and added new function sicl_server_new_channel that handles the
7337 incoming New Channel packet. Added also new sending function
7338 silc_server_send_new_channel to send New Channel Payload.
7340 * Added new function silc_server_notify to process incoming notify
7341 packet to the server/router. Server may then relay the notify
7342 to clients if needed.
7344 * Added new function silc_server_new_channel_user to process incoming
7345 New Channel User packet. Router will redistribute the packet and
7346 send JOIN notify to its local clients and locally connected servers
7347 if needed. Normal server will send JOIN notify to its local client
7348 on same channel when received this packet. Added also corresponding
7349 sending function silc_server_send_new_channel_user to sent the
7352 * Added boolean route argument to send_notif_to_channel and
7353 packet_send_to_channel functions to attempt to route the packet
7354 if it is TRUE and send only locally if it is FALSE.
7356 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7358 * silc_server_replace_id now broadcasts the received replace ID
7359 packet if it is not broadcast packet already. The router must
7360 broadcast to inform other routers about changed ID.
7362 * Added backpointer to server's router into SilcServer context in
7363 silcd/server_internal.h.
7365 * Fixed silc_server_packet_broadcast to send correct broadcast
7368 * The channel key is now distributed to the local client as soon
7369 as it is received from the router (in router environment) so that
7370 no other packet may be sent for the channel until client has
7373 * silc_server_remove_channel_user now broadcasts the received
7374 Remove Channel User packet if it is not broadcast packet already.
7375 The router must broadcast to inform other routers about removed
7378 * Added users field into SilcPacketContext that is a reference count
7379 of the context. One can increase the reference count by calling
7380 silc_packet_context_dup which is now changed to just increase the
7381 reference count instead of duplicating the data. The reference
7382 count is decresed by calling silc_packet_context_free that will
7383 free the data after the reference count hits zero.
7385 For now on the packet context and everything allocated into it
7386 (including the raw packet from network) must be freed by calling
7387 the new silc_packet_context_free function. Added also new function
7388 silc_packet_context_alloc that must be used now to allocate the
7389 context. This also means that if a routine is asynchronous from
7390 silc_[client/server]_packet_parse_type the packet context must
7391 be duplicated by calling silc_packet_context_dup. Otherwise it
7392 gets free'd after silc_[client/server]_packet_parse_type returns.
7393 Also, one must remember that if packet is duplicated then its
7394 reference count must be decresed by calling the free function as
7395 many times as it was duplicated.
7397 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7398 from both client and server.
7400 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Made joining to a channel working in router environment.
7404 * Cleaned up JOIN command on server side and create function
7405 silc_server_command_join_channel internal routine to make the
7408 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7410 * Changed silc_command_pending list to SilcDList. Also, added
7411 `ident' field to SilcServerCommandPending structure to identify
7412 the reply and to call correct callback.
7414 Added silc_server_command_pending_check function to replace the
7415 corresnponding macro. The silc_command_pending list is not
7418 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7419 to set identifier to previously allocated Command Payload. It
7420 is used to set identifier for command when resending Command
7423 * Added silc_command_payload_encode_payload to encode Command
7424 Payload buffer from SilcCommandPayload structure.
7426 * Added silc_argument_payload_encode_payload to encode Argument
7427 payload buffer from SilcArgumentPayload structure.
7429 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Changed WHOIS command to support router connection on server side.
7432 The whois request is always sent to router unless the server is
7433 standalone server. After server has received the reply from the
7434 router will it send the reply to the client.
7436 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7437 broadcast received broadcast packet. The function is used only
7438 by router. The broadcast packet is always sent to the router's
7441 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7442 render given ID to printable string, for log files for example.
7444 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7446 * Made basic router to router connections working. At least they
7447 can now connect to each other but nothing really works the way
7448 they are supposed - yet.
7450 * Added new initiator token to RouterConnection configuration
7451 file in silcd/serverconfig.[ch]. It is used to tell whether we
7452 are the initiator to the remote router or whether we'll expect
7453 the other end to connect.
7455 * Moved registering of listener task to silc_server_init, hence
7456 the server starts listenning as soon as it is run, even if it
7457 does not have connections to other routers. Let's see how well
7460 * Changed default connection retry timeouts for more suitable in
7463 * Removed cipher and such arguments from silc_idlist_add_client
7464 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7465 Added new function silc_idlist_add_data to add the keys and stuff
7468 * Added SilcIDListData structure and added it to SilcClientEntry
7469 and SilcServerEntry as their first field in the structure. This
7470 way we can explicitly cast the ID entries to the SilcIDListData
7471 structure and get common data for the entries. In past, we had
7472 to first check what type of connection it is and then cast it to
7473 correct ID entry type. Now, we can directly cast the opaque
7474 pointer to the SilcIDListData (no matter what ID entry it actually
7475 is) and get the data needed.
7477 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7480 in some circumstances even if threre were timeout tasks, though not
7481 IO tasks, but tasks anyway. Now fixed.
7483 * Defined SilcServerConnection structure to hold connection specific
7484 stuff about directly connected servers and routers. The definition
7485 is currently in silcd/server_internal.h. I thought about having
7486 a bit more important role fro this struct but for now it is used
7487 only when connecting to other server (or router actually).
7489 * Added connecting retry support in server when connecting to
7490 router(s). The retry feature implement exponential backoff
7491 algorithm. Also, added SilcServerParams structure to hold default
7492 parameters for server. For now, it include these retry settings
7493 and are hard coded. After server is moded to be as Silc Server
7494 Library this structure will be more important.
7496 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7498 * Changed client librarys channel->clients table to SilcList and
7499 changed code accordingly.
7501 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Changed client's channel table to SilcList and changed code
7504 accordingly. Also changed SilcChannelClientEntry to include back-
7505 pointer to the channel so that client entry can use that structure
7506 as list as well and we have fast cross-reference to the channel.
7507 This change dramatically decreased the complexity of channel
7508 handling with client entry and vice versa (removed one extra
7509 loop when searching for channel entry from many functions).
7511 * Changed server->sim from table to SilcDList and changed code
7514 * NAMES command can now be used from user interface. It will show
7515 the user list on the channel, neatly.
7517 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7518 Code now saves realname of the user if it becomes available.
7520 * Renamed configure.in to configure.in.pre and made ./prepare
7521 script to automatically add correct version string to
7522 configure.in which it creates from configure.in.pre.
7524 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * NAMES command reply now shows users mode with the nickname when
7529 * Moved silc_client_ch[u]mode[_char] functions from
7530 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7531 place sucks, they are utility functions and should be in some
7534 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7536 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7539 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7543 * Added TRQ (efficient deque and list library) into lib/trq. This is
7544 a very good list library that is currently used in the SILC. Defined
7545 SilcList API over the library because I didn't like the API very
7546 much. See lib/trq/silclist.h for the API and examples of how to
7547 use the API. Fixed various places in the code to use the new
7548 SilcList API. The SilcList is meant for lists that has a structure
7549 already defined as a list. It is not suitable to add just some
7550 context to the list (in TRQ, the context is the list actually).
7552 So, I defined SilcDList that can be used for the purpose where
7553 predefined list structure does not exit. This can be used as
7554 such list. Now some context just can be added to the SilcDList.
7555 Currently this list is not used in the SILC just yet, though there
7556 are a lot places where this can replace dynamically allocated
7557 tables and I will fix these places, later, to use SilcDList.
7558 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7559 and use TRQ internally).
7561 Also fixed some annoying warning messages that the original TRQ
7562 code generated. Also minor changes to TRQ's Makefile.in.
7564 * Added support for querying by Client ID to both WHOIS and
7565 IDENTIFY commands into server, as required by the protocol.
7567 * Removed method function pointers from SilcBuffer structure. They
7568 weren't used to anything and just increased the context size for
7569 no good reason. This change also made silc_buffer_alloc and
7570 silc_buffer_free functions inline functions.
7572 * Disabled command flooding detection support until it's fixed so
7573 that it accepts commands in but does not execute them more than once
7576 * Added silc_net_localhost(), to return local hostname, into
7577 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7578 that must be initialized before calling silc_client_init.
7580 * Added new function: silc_server_send_notify_on_channels to send
7581 notify messages to all channels client has joined. It is assured
7582 that the message is sent only once per client.
7584 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7585 lib/silcutil/silcutil.[ch] as silc_format function. The new
7586 function is generic and is used by server as well, not only by
7587 the logging routines.
7589 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7590 the provided version string was not acceptable. Added new function:
7591 silc_ske_check_version into lib/silcske/silcske.h. The function
7592 must be implemented by the application (client or server) and it
7593 does not reside in the SKE library. The function checks the version
7594 string remote end sent.
7596 * Added back pointers (to opaque context and to SilcSocketConnection)
7597 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7599 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7600 duplicate packet context structure.
7602 * Changed `notify' client operation to send same arguments as client
7603 receives from server except for ID's. ID's are mapped to correct
7604 ID entry and that is returned. Also, if channel entry is not sent
7605 by server but the notify is for channel the channel entry is sent
7606 to application (otherwise application doesn't know that it is for
7607 channel (library gets it from packet's Destination ID)).
7609 * Added silc_client_remove_from_channels into client library to
7610 remove a client from all channels it has joined to. Used when
7611 received SIGNOFF notify from server. Added also new function
7612 silc_client_replace_from_channels to replace old ID entry with
7613 new ID entry on all channels. Used when received NICK_CHANGE
7616 * Fixed ID Cache list handling in silc_idlist_get_client in
7617 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7618 to get (or query) client by ID.
7620 * Updated TODO list.
7622 * Added connection authentication status message defined by the
7623 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7624 support for these into the code in client and server side.
7626 * Added generic function silc_client_send_command to send any command
7627 with variable argument list. Application should use this function
7628 to send commands if the command functions provided by the library
7629 does not suite for the application's user interface needs.
7631 * Added new `failure' client operation. Application is notified about
7632 received failure packet if client is executing a protocol. In this
7633 case the protocol's execution has failed.
7635 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7636 is required by the protocol.
7638 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7639 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7642 * Added status flag to SilcSKE object to indicate realtime status
7643 of the SKE protocol.
7645 * Application receives now exactly same command reply arguments as
7646 the library receives from server. However, if ID is received the
7647 corresponding ID entry is returned to the application (eg. Client
7648 ID is mapped to correct SilcClientEntry entry and that is returned).
7649 Changed command_reply client operation due to this change.
7651 * Changed all ID's in commands and in command replys as ID Payloads.
7652 Change affected both client and server side codes.
7654 All ID's sent in SILC network (with execption of ID's in SILC
7655 Packet header) are sent in ID Payload to support variable length
7658 * Server now notifies nick changes and notifies all clients on
7659 the channels about the new nickname (about the new Client ID,
7662 * Implemented CMODE command to change channel modes. Supports all
7663 channel modes defined by the protocol specs except ban and invite
7664 lists. (Also, private channel key mode is supported but support for
7665 setting private channel key in client is missing, thus, this mode
7666 has no effect on client side (except that server requires that the
7667 client uses private channel key and normal channel traffic does not
7670 Also, invite mode works per se, but INVITE command does not work
7671 yet correctly, so you can set channel as invite only channel but
7672 inviting clients to the channel does not work (it is yet to be
7673 thought what's the best way to do it).
7675 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7676 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7677 Implemented CUMODE command to change user's mode on the channel.
7678 Supports all modes defined by the protocol specs.
7680 * Added NAMES command reply to return users modes on the channel.
7682 * Removed unnecessary and slow ciphers from lib/silccrypt.
7684 * Set SO_KEEPALIVE option to connection sockets by default.
7686 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7688 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7689 redefined the Notify Payload into protocol specs.
7691 * Added silc_id_payload_parse_id to get ID directly from raw
7694 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7697 accept searching by Client ID as well.
7699 * Added support for LEAVE and SIGNOFF notify types in client library.
7701 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7702 to parse ID Payload from raw data.
7704 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7706 * Added flags parameter into silc_ske_assemble_security_properties
7707 function in lib/silcske/silcske.[ch].
7709 * Changed notify client operation to fit better for notify messages
7710 sent by server. The notify payload received from server is now
7711 passed to the application (after parsing it to SilcNotifyPayload).
7712 It is application's responsibility to retrieve the arguments
7713 from the payload and show the message the way it wants. The message
7714 sent by server is implementation specific.
7716 * Changed public keys to comply with the protocol specification.
7717 Old public keys are not supported anymore and are not compatible.
7719 * Removed nickname from Channel Payload as the latest draft removed
7720 it. The client must resolve the nickname from the NAMES command
7721 reply received when it joined the channel.
7723 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7725 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7727 * Fixed some errors in protocol specification drafts.
7729 * Created lib/silccore/silcnotify.c to implement Notify Payload
7730 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7731 generic payloads described by protocol specifications. The file
7732 includes implementations for ID Payload and Argument Payload.
7734 * Changed Command Payload implementation to use the new Argument
7735 Payload. Changed command_xxxx_payload to command_payload_xxxx
7736 to comply with SILC coding conventions.
7738 * Added suppport for Argument Payload handling in Notify Payload
7739 implementation as protocol requires it. Added the new support
7740 into server and client lib as well.
7742 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Added support for multiple nicknames on same channel. [n] is
7745 added locally to the nickname if there are more than one same
7746 nicknames on the channel.
7748 * Server now sends all nicknames that matched WHOIS request.
7749 Client also shows the list received from server.
7751 * Added TOPIC command to client side. User can now set and show
7752 current topic on channel.
7754 * Added MOTD command to client and server. Also, server sends the
7755 motd when client connects to the server.
7757 * Changed version strings to comply ISO 8601.
7759 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7761 * Fixed protocol error handling in client library. It should now
7762 cope even if the SKE fails for some reason.
7764 * Made new protocol specification drafts for submitting to IETF.
7766 * Implemented TOPIC command to server in silcd/command.c.
7768 * Added two new notify types into lib/silccore/silcnotify.h:
7769 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7770 notify nickname change and topic setting/change on a channel.
7772 * API change of command_reply operation in client library. The
7773 application gets now the status type received from server as well.
7775 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7777 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7779 * Cras fixed and optimized the packet handling even further and
7780 it should work now. Minor change to the prototype of function
7781 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7783 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * Added new function into lib/silcutil/silcschedule.[ch]:
7786 silc_schedule_with_fd to select() a specified fd. The function
7787 returns after timeout expires or data arrives or goes. The
7788 function is used by packet routines to wait that all data is
7789 received from network.
7791 * Fixed data reading from network in lib/silccore/silcpacket.c.
7792 The code now assures that all data is read from the fd and then
7793 continues packet processing. This was a bug fix since the code
7794 used to drop some data in some circumstances.
7796 * Added new function into lib/silcclient/client.[ch]:
7797 silc_client_start_key_exchange to start key exchange after
7798 connection has been established to server. The code internally
7799 now uses this funtion but its main purpose was to provide it
7800 for applications that perform their own connecting. After
7801 application has created a connection it merely calls this
7802 function to start the key exchange between client and server.
7803 The library takes care of everything else after that.
7805 Updated also lib/silcclient/README to explain the usage of
7808 * Do not send to application information that connection has
7809 been established. Application gets notified it by connect
7812 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7814 * Applied cras's patch to add silc_schedule_one function. The
7815 function runs scheduler once and returns.
7817 * Fixed the scheduler after cras messed it up. The timeout
7818 handling works now as it's supposed to work.
7820 * Added into lib/silccore/ silcnotify.h to include notify
7821 message types support. Changed silc_server_send_notify*
7822 functions, in server.[ch], to support those new notify types.
7823 Added the support for the notify types into client library,
7824 as well. Added new notify client operation into ops.h in
7827 * Changed silc_server_packet_send_to_channel to send normal
7828 packets instead of just channel message packets. The function
7829 is now used to send the notify packets to channels. It is not
7830 used to send channel message packets anymore, as server never
7833 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7834 va_arg()s as it seems to require it nowadays. I guess, if SILC
7835 is compiled with older va_arg() the new code should work anyway.
7837 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7839 * Splitted core library. Core library (lib/silccore) includes
7840 now only SILC protocol specific core (and common) components.
7841 Created new utility library (lib/silcutil) that includes more
7842 generic purpose stuff. The stuff for util library was taken
7843 from the old core library. This was minor and easy split.
7845 * Created SILC Client Library (lib/silcclient) that includes
7846 implementation of the SILC client without user interface. This
7847 was major move from silc/ directory. The code has been changed
7848 so that it is transparent towards the user interface. The
7849 silc/ directory includes now the same user interface as before
7850 and it uses the new client library. Read lib/silcclient/README.
7851 Basicly, the client library performs everything else related
7852 to SILC except user interface handling. Also, configuration
7853 files are considered to be part of user interface and library
7854 does not handle them.
7856 This change also changed a lot of structures, function naming etc.
7857 Most important change was that SilcClientWindow object was
7858 renamed to SilcClientConnection in the client library. Created
7859 also new file lib/silcclient/ops.h. Also added new files
7860 silc/local_command.[ch] and silc/client_ops.[ch].
7862 All these changes were made to make it easier for user interface
7863 designers to create what ever user interface for the SILC client
7866 It is also expected that the server will be moved to lib
7867 directory as well and SILC Server Library will be created;
7868 sometimes in the future.
7870 * Removed Local commands from lib/silccore/silccommand.h as
7871 they are application specific and new client library does not
7872 handle any of those anymore.
7874 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7875 old client implementation in silc/.
7877 * Added support for callback functions in SILC_LOG_* macros.
7878 Application can now set its own callbacks that will be called
7879 instead of using the default functions that will always print
7880 the debug messages to stderr (or stdout). Also, debugging can
7881 now be disabled by setting silc_debug to FALSE and re-enabled by
7882 setting it to TRUE. Note, that logging will still work even
7883 if debugging is disabled.
7885 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7886 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7887 silc_log_reset_debug_callbacks.
7889 * To enable debugging in silc client one must give now -d
7890 option on command line.
7892 * Changed silc_schedule_init to automatically allocate task queues
7893 if they are not allocated before calling it.
7895 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Added GMP 3.1 into math library.
7899 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7901 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7902 a channel in SILC network. The packet is used by servers and
7903 routers to notify other routers that user has left a channel.
7904 This little feature was missing until now. Added the feature
7905 to protocol specification as well.
7907 Added functions: silc_server_send_remove_channel_user and
7908 silc_server_remove_channel_user into server.[ch].
7910 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7911 lib/silccore/silcpacket.h. However, they are not implemented
7914 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7916 * Fixed joining to a channel and sending channel messages
7917 between server and router. The channel message sending should
7918 now work inside a cell.
7920 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7922 * Fixed the private message sending between server and router.
7923 The private message sending should now work inside a cell.
7925 * Added silc_server_replace_id into server.[ch] to replace
7926 existing ID in the SILC network.
7928 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7929 and silc_idlist_replace_server_id into idlist.[ch] in server.
7931 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7933 * Fixed the server to server connections. Server can again now
7934 connect to router. Router to router connections probably does
7937 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7939 * Added dynamic protocol registering support. Now protocols can
7940 registered and unregistered on the fly. Patch by cras.
7942 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Added lib/contrib directory to hold routines that some platforms
7945 don't have but are needed by SILC.
7947 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7948 into lin/contrib to provide getopt() and getopt_long() for
7949 those who don't have it.
7951 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7953 * Added AWAY command to client. When away message is set and
7954 client receives a private message packet the client automatically
7955 replies to the sender with the away message.
7957 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7958 bug seemed to be the cause of recent problems when compiling
7961 * Added version detection support to SKE protocol specification
7962 and added the new changes to the SKE implementation as well.
7963 There were other minor changes in the SKE protocol as well.
7965 Many changes in lib/silcske/silcske.[ch] and in
7966 lib/silcske/payload.[ch].
7968 * Added ^U functionality, clear input line. Patch from cras.
7970 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7972 * Mainly small bugfixes on core library. Fixed some debugging
7973 logging and buffer overflow in silclog.c.
7975 * Updated config.sub and config.guess on the distribution tree.
7977 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7979 * Added command lagging support in server. Client may execute
7980 commands now only once in two seconds.
7982 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7984 * Optimized packet reception. MAC computation and checking is now
7985 also more optimized. A lot previously duplicated code is now
7986 used as generic by both client and server.
7988 * Fixed key pair generation in clientutil.c
7990 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7992 * Added into lib/silccore/silcbufutil.[ch] new function;
7993 silc_buffer_realloc.
7995 * Moved generic packet sending/encryption functions to
7996 lib/silccore/silcpacket.[ch] from client and server. Some
7997 rewriting of the functions.
7999 * Moved all generic packet reception/decryption functions to
8000 lib/silccore/silcpacket.[ch] from client and server. The
8001 packet processing is now much cleaner in both client and server.
8002 These were major changes in both client and server.
8004 * Created many common functions in server to do packet sending.
8005 Previously code were duplicated a lot, this has been removed
8008 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8010 * Rewrote major parts of the ID cache system. Don't know
8011 whether it is better now or not but at least the API is more
8014 * Major rewrite on ID cache stuff on client because of the ID
8015 cache API changes. Added idlist.c to client.
8017 * Also major rewrite on ID cache stuff on server as well.
8018 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8019 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8020 in hand, instead they are all put into the ID cache system now.
8021 All server_idlist_* routines uses ID cache now instead of
8022 traversing its own lists (those lists does not exist anymore).
8023 SilcIDList though still exists. Also, SilcXXXEntry's are
8026 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Finally made the SKE implementation compliant to the protocol
8029 specification. All mp integers are now binary encoded as
8030 opposed being HEX encoded.
8032 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8035 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8036 functions: silc_[encode/decode]_pem. Also added function
8037 silc_encode_pem_file to PEM encode with newlines ('\n') for
8040 * SILC public keys are now encoded either PEM or binary. Same
8041 option is for private keys as well. By default private keys
8042 are binary encoded and public keys PEM encoded. Silly HEX
8043 encoding were removed.
8045 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8046 function to create fingerprints.
8048 * Fixed a bug in SHA1; does not change the original data anymore.
8050 * Partly implemented INFO command on client and server side.
8051 Fixed CLEAR command. Changes to SERVER command; show current
8052 server(s) when giving command without arguments. Added
8053 VERSION command to client.
8055 * Added check to server that unregistered connections cannot
8056 execute commands (unless it is specificly allowed).
8058 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8060 * Fixed screen refresh.
8062 * Fixed channel joining bug from client. On some circumstances
8063 client tried to join to a channel it had already joined.
8065 * Added public key verification process into client's protocol.c.
8066 The client now verifies the public key from user and saves
8067 it into ~./silc/serverkeys/ directory.
8069 Added into: clientutil.[ch]: silc_client_verify_server_key.
8071 * Changed SKE protocol's silc_ske_initiator_finish function
8072 to accept callback function that verifies the received public
8073 key. Removed old silc_ske_verify_public_key function.
8075 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8077 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8078 silc_pkcs_private_key[_data]_set.
8080 * Made the password and public authentication more cleaner in
8081 server's protocol.c.
8083 * Removed historic and obsolete protocol `channel_auth' from
8084 both client and server.
8086 * Removed wrong way of sending command status messages from
8087 server to client in server's command.c. The old way violated
8088 protocol specification.
8090 Changes to silccore/silccommand.[ch]: removed
8091 silc_command_encode_status_payload -> not needed anymore,
8092 changed silc_command_encode_payload_va to accept extra
8093 argument on variable argument list. The argument type must
8094 now be provided to the function. Also, added new function:
8095 silc_command_encode_reply_payload_va which is same as
8096 normal command_encode_payload_va except command status type
8097 is provided as extra argument.
8099 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8101 * Added ~./silc directory handling. The directory includes the
8102 public and private keys for the client.
8104 Added silc_client_check_silc_dir, silc_client_create_identifier
8105 and silc_client_load_keys.
8107 * Implemented SILC protocol compliant public key. Added public
8108 and private key saving to and loading from files.
8110 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8111 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8112 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8113 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8114 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8116 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8117 silc_pkcs_load_[public/private]_key.
8119 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8121 * Added silc_server_get_route (route.[ch]) to get connection
8122 data for the fastest route for given ID.
8124 * Implemented INVITE command on client and server. The command
8125 were re-defined in the SILC Protocol Specification and the
8126 implementation now complies with the specification.
8128 * Implemented PING command on client and server.
8130 * Implemented NAMES command on client and server. The server side
8131 supports currently only normal server not router server yet.
8132 Some changes to NAMES definition in SILC protocol specification.
8134 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8136 * Implemented LEAVE command on client and server.
8138 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8139 again. This change was made to the protocol as well. Server
8140 should not violate the protocol specification anymore.
8142 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8144 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8145 was tested. SOCKS4 was not but should work anyway.
