1 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added new user modes ANONYMOUS for special anonymous servers
4 that may set the mode for client, and BLOCK_PRIVMSG which
5 client may set to block incoming private messages unless the
6 Private Message Key flag is set (using private keys to protect
7 private messages). Updated protocol specs and code in client
8 and server and core library. Protocol TODO #23. Affected
9 files are lib/silccore/silcmode.h, silcd/server.[ch],
10 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
11 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
13 * Added new channel user mode BLOCK_MESSAGES which the client
14 may set to itself to tell server not send channel messages.
15 Other packets such as channel key packets are still sent.
16 Protocol TODO #23. Updated the protocol specs, client and
17 server. Affected files are lib/silccore/silcmode.h,
18 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
19 lib/silcutil/silcutil.c, silcd/command.c, and
22 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
24 * Redefined the Status Payload to include now two 8 bit fields,
25 instead of one 16 bit field. This now makes it possible to
26 send list of errors. Updated the protocol specs and the code
27 in core library, client library and server. Protocol TODO #1.
28 Affected files are lib/silccore/silccommand.[ch],
29 lib/silcclient/command_reply.[ch], silcd/command.c,
30 silcd/command_reply.c and silcd/packet_receive.[ch].
32 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
34 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
35 must be handled by the application and should tell the application
36 that an error message was already printed, and it should print the
37 config coords (line, filename, ...). Affected files are
38 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
40 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
41 server config parsing code more readable.
43 Fixed a bug in the fetch_logging() config callback.
45 Affected files is silcd/serverconfig.c.
47 * Drop root privileges when started in foreground. Don't drop them
48 if debugging also. Affected file is silcd/silcd.c.
50 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
52 * Added more IM-like features by introducing new user modes
53 for setting various presence information. Added new modes:
54 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
55 specs and code. Protocol TODO #19. Affected files are
56 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
57 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
59 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
61 * Added STATS command to the protocol after all, to return
62 various statistical information about the network. It can
63 be used by clients to retrieve statistical information, and
64 servers may use it to to fetch cell and network wide
65 statistics from router. Updated the protocol specs and
66 implemented it to the server. Protocol TODO #16.
67 Affected files are lib/silccore/silccommand, silcd/command.[ch],
68 silcd/command_reply.[ch].
70 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
72 * The LIST command reply in client libary now adds new channel
73 entry if the returned channel doesn't exist yet in cache,
74 and returns the channel entry to the application in the
75 command_reply client operation. Affected file is
76 lib/silcclient/command_reply.c.
78 * Changed the channel message payload's MAC generation to
79 include the IV in the MAC as well. This way all relevant
80 parts of the channel message payload are authenticated also
81 with the channel message MAC (and not only by packet MAC).
82 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
83 Affected file is lib/silccore/silcchannel.c.
85 * Fixed the SKE to save the remote version, since the
86 silc_ske_parse_version mistakenly checked wrong version,
87 after it replaced the start payload. Affected files are
88 lib/silcske/silcske.[ch].
90 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

97 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
98 files are lib/silcutil/silcstrutil.[ch].
100 * Defined that the security property fields in SKE SHOULD be
101 UTF-8 encoded, defined that version string MUST be US-ASCII
102 encoded, defined that passphrases sent in connection
103 authentication protocol MUST be UTF-8 encoded. Implemented
104 these to the client and server. Defined also that other
105 passphrases sent in the protocol MUST be UTF-8 encoded.
106 Affected files are lib/silcske/silcske.c,
107 lib/silcclient/protocol.c, silcd/protocol.c,
108 silcd/serverconfig.c, and lib/silccore/silcauth.c.
110 * Changed the silc_client_close_connection interface to not
111 need the SilcSocketConnection which should not be visible
112 to application. Affected files are lib/silcclient/client.c
113 and lib/silcclient/silcclient.h.
115 * Rewrote the text for Private Message Key Payload in the
116 protocol specification. Protocol TODO #11.
118 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
120 * Upgraded the protocol version to 1.1, updated protocol specs
123 * Added the nickname as new argument to NICK_CHANGE notify and
124 added it to protocol specs and implemented it to client and
125 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
126 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
127 lib/silcclient/client_notify.c.

131 Protocol TODO #13. Affected files are silcd/command.c,
132 silcd/packet_receive.c, packet_send.[ch],
133 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
134 The killer's client entry is now returned to application in
135 the `notify' client operation.
137 * Fixed the Max Argument fields that had too large value set
138 in the protocol specs. Protocol TODO #14.
140 * Added the LEAVE command reply to return the ID of parted
141 channel. Updated protocol specs and implemented it to the
142 client and server. Protocol TODO #15. Affected files are
143 silcd/command.c, lib/silcclient/command_reply.c. The channel
144 entry is now returned to application in the `command_reply'
147 * Rewrote the version SKE version checking in client libary
148 and in server to use the silc_parse_version_string. Affected
149 files are lib/silcclient/protocol.c, silcd/protocol.c.
151 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
152 commands that was missing it, and updated protocol specs and
153 the server implementation. Protocol TODO #10. The affected
154 file is silcd/command.c.
156 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
157 generic reply to a generic request (REQUEST flag), and
158 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
159 way. A draft-riikonen-silc-flags-payloads-00.txt is written
160 to define the payload for DATA flag. Added the flags to
161 the implementation. Protocol TODO #9. Affected file is
162 lib/silccore/silcchannel.h.
164 Changed the client library to return the message length
165 to application as well in the channel_message and private_message
166 client operations. Affected files are
167 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
168 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
169 and lib/silcclient/client_ops_example.c.
171 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
172 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
173 the channel. Updated protocol specs and impelemented this
174 to client and server. Protocol TODO #6. Affected files are
175 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
176 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
178 Added new options m and M to CMODE command in Irssi SILC
179 client to set these modes.
181 * Deprecated all administrative commands from SILC protocol
182 since they are highly implementation specific commands.
183 Updated protocol specs. Moved the old commands in
184 implementations to private range of command types. Affected
185 files are silcd/command.c, lib/silcclient/command.c and
186 lib/silcclient/command_reply.c. Protocol TODO #8.
188 * Fixed a bug in server where sending unknown command crashes
189 the server. Affected file silcd/command.c.
191 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
193 * Added SILC_PROTOCOLVERSION macro to check protocol version
194 of a socket connection. The affected file is
195 lib/silcutil/silcsockconn.h.
197 * Added better error logging in rekey protocol. Affected file
200 * Do not check public key types in SKE during rekey. Affected
201 file lib/silcske/payload.c.
203 * Fixed the rekey protocol with PFS, which was totally broken.
204 Affected file silcd/protocol.c.
206 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
208 * Some client implementations quit network by doing first LEAVE
209 and then immediately SIGNOFF (like Bombyx). We now do check
210 after a short time after LEAVE notify and check whether the
211 client is still valid after LEAVE, and if not we remove it from
212 cache. Affected file is lib/silcclient/client_notify.c.
214 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
216 * Merged version 1.1.4 of zlib. Even if it not currently in use,
217 it's good not to have security holes here.
219 * Fixed a negative refcount situtuation for the config context.
220 Affected file is silcd/serverconfig.c.
222 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
224 * ROBOdoc documented lib/silcutil/silcutil.h.
226 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Optimized even more the SilcPacketContext structure. Now
229 totally saved 16 bytes of memory per context after optimization.
230 Affected files are lib/silccore/silcpacket.[ch].
232 * Made strict checks for valid SILC IDs. Affected file is
233 lib/silccore/silcid.c.
235 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
237 * Changed the object argument for silc_cipher_register,
238 silc_hash_register, silc_hmac_register and silc_pkcs_register
239 to const. Affected files are lib/silccrypt/silccipher.[ch],
240 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
242 * Changed the silc_get_username and silc_get_real_name to
243 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
245 * Fixed the Irssi SILC Client to use the silc_get_username and
246 silc_get_real_name insted of glib routines since the glib
247 routines only corrupt stack. Fixes the Irssi SILC to work in
248 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
250 * Fixed the Irssi to not use g_get_home_dir since it crashes
251 or returns garbage on cygwin and corrupts stack. Added function
252 get_home_dir to Irssi routines. Affected files are
253 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
255 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Made some structure optimizations. SFTP memory FS MemFSEntry
258 entry structure. Optimized SilcTask structure. Optimized
259 SilcPacketContext structure.
261 Affected files lib/silcsftp/sftp_fs_memory.c,
262 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
264 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
266 * And yet again reverted back the config thing since Johnny
267 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
270 * Fixed memory leaks from config object. Affected files are
271 silcd/serverconfig.[ch].
273 * Added support for adding new connections to the server in rehash.
274 After rehash they take effect.
276 Added support for changing the maximum allowed connections in
277 rehash. The number can grow but going smaller is not supported.
279 Added function silc_server_num_sockets_by_remote to the
280 silcd/server_util.[ch].
282 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
284 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
286 * Added preliminary checking during config parsing for a valid
287 public/private key and removed further checks in the code.
288 Affected files are silcd/serverconfig.[ch], server.c.
290 * Moved functions silc_server_drop() and silc_server_daemonise()
291 from server.c to silcd.c since they are stricly related to
292 the application activity.
294 * Reverted a small part of the automatic ref/unref since
295 it caused a double unref in some situations. Affected
296 files are silcd/silcd.[ch], server.c, serverconfig.c.
298 * Added some .cvsignore files in the lib directory.
300 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
302 * Fixed silc_net_gethostbyaddr to correctly resolve by
303 address. Affected file lib/silcutil/silcnet.c.
305 * Fixed the notify relaying to client. The HMAC to be used
306 with relayed packets ws wrong and caused decryption failure
307 at the client end. Affected file is silcd/packet_receive.c.
309 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
311 * Created new branch silc_protocol_1_0_branch.
313 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
315 * Changed the silc_server_config_* routines to be SilcServer
316 independent. They are now officially application specific code
317 and not part of generic server implementation. Affected files
318 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
320 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
322 * Added automatic referencing of config context in the
323 silc_server_config_alloc, and automatic unreferencing in the
324 silc_server_config_destroy. Affected files are
325 silcd/serverconfig.[ch], silcd/silcd.c.
327 * Fixed the silc_log_quick handling in the logging routines.
328 It didn't log quickly when it was TRUE. Affected file is
329 lib/silcutil/silclog.c. Also the flush delay was set even
330 if it was 0 in config file. Affected file is
331 silcd/serverconfig.c.
333 * Added support for changing key pair of the server in rehash.
334 Affected file silcd/server.c.
336 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
338 * Fixed the TOPIC_SET notify to not cras. It changed the topic
339 too early, before getting the channel entry. Affected file
340 is silcd/packet_receive.c.
342 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
344 * Added functions silc_server_config_[ref/unref], these are used
345 to prevent that the config object is destroyed.
347 No longer directly affect global variables silc_log_quick and
348 silc_log_delay, they are first cached inside the config object
349 and then applied with silc_server_config_setlogfiles().
351 silc_server_config_set_defaults() is now internal to
352 serverconfig.c, there are no reasons to show this internal stuff
355 Affected files are silcd/serverconfig.[ch].
357 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
358 fprintf's to stderr, since some code may be executed again after
359 the server went into the background. Affected files are
362 * Added rehash support. Added function silc_server_rehash() that
363 will perform all the basic tasks of the rehashing procedure.
365 * Added command line option `-x, --hexdump'. This will enable the
366 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
367 The option `--hexdump' implies `--debug'.
369 * Fixed a bad bug in the logging APIs (silcutil library) where
370 the application would crash after calling silc_log_reset_all().
372 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
374 * Fixed the KICKED notify handling in client library to
375 correctly remove the channel and all entries from the
376 channel when I was kicked. This bug crashed the client.
378 Fixed yet another but in KICKED notify handling to remove
379 the kicked client correctly from the channel.
381 Affected file is lib/silcclient/client_notify.c.
383 * Fixed a minor bug in looking up correct client entry
384 in KICKED notify in server. Affected file is
385 silcd/packet_receive.c.
387 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
388 sources correctly to distribution. Fixes --with-gmp option.
390 * Removed the manual rehashing from ID Cache, and changed it
391 to use the SILC Hash Table's auto rehash feature. Affected
392 file is lib/silccore/silcidcache.c.
394 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
396 * Fixed a bug in the silc_client_nickname_format function that
397 handles the multiple same nickname formatting. Two clients
398 with same nickname caused problems after the first one left
399 and rejoined. It didn't format the nickname correctly.
400 Affected file is lib/silcclient/idlist.c.
402 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
404 * Don't change the topic if olod topic is same as new one.
405 Affected file is silcd/packet_receive.c.
407 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Added cross-reference support to the SILC Documentation
410 generator. All types across all HTML files are now cross-
411 referenced. Affected files util/robodoc/generator.c and
412 scripts/silcdoc/silcdoc.
414 * Added file lib/silcutil/silctypes.h to include all the
415 arithmetic type definitions and some macros. Removed
416 includes/bitmove.h and moved macros to silctypes.h.
418 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
420 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
422 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
424 * Added `type' argument to silc_id_payload_parse_id function which
425 now returns the type of the ID to the sent pointer. Affected
426 file is lib/silccore/silcid.[ch].
428 * Added check for CMODE_CHANGE notify type that mode change is
429 allowed by the sender. Affected file silcd/packet_receive.c.
431 * Added check for CUMODE_CHANGE notify type that mode change is
432 allowed by the sender. Affected file silcd/packet_receive.c.
433 Added the ID type as CUMODE_CHANGE notify type as argument
434 to the `notify' client operation. Affected files are
435 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
437 * Added function silc_client_add_server to the client library.
438 Added support for resolving also channel and server info when
439 received unknown entity in notify packet. Affected files are
440 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
442 * Added function silc_command_get_status to return the command
443 status from the command reply's argument payload. Affected files
444 are lib/silccore/silccommand.[ch].
446 * Added check for KICKED notify type that the kicking is
447 allowed by the client. Affected file silcd/packet_receive.c.
449 * Created function silc_get_input which can be used to get input
450 (echo on or off) from user on command line. Affected files are
451 lib/silcutil/silcutil.[ch].
453 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Optimized silc_server_packet_relay_to_channel function.
456 Added new function silc_channel_message_payload_encrypt which
457 can be called directly if channel message payload needs to
458 be encrypted and is already encoded (no need to call _encode
459 function). Packet relaying is now done by router without any
460 extra memory allocations. Affected files are
461 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
464 * Fixed the INVITE notify handling. It took wrong arguments
465 as invite list and invite delete. Affected file is
466 silcd/packet_receive.c.
468 * Added check for TOPIC_SET notify type that the topic change is
469 allowed by the client. Affected file silcd/packet_receive.c.

476 silc_server_check_cmode_rights to server_util.[ch].
477 Affected files are silcd/server_util.[ch], silcd/command.c.
479 * Added function silc_server_check_umode_rights to check whether
480 changing client's user mode is allowed. Added check for
481 UMODE_CHANGE notify type that the umode change is allowed
482 by the client. Affected files are silcd/server_util.[ch],
483 silcd/packet_receive.c and silcd/command.c.
485 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
488 ID length. It ignored that ID can be IPv6 based as well.
489 Affected file lib/silccore/silcpacket.h.
491 * Fixed the silc_id_id2str and silc_id_str2id to take the
492 IPv6 address offset's into consideration. Affecte file is
493 lib/silccore/silcid.c.
495 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
497 * Fixed the internal Unix scheduler functions to check for
498 NULL context they may receive. The affected file is
499 lib/silcutil/unix/silcunixschedule.c.
501 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
503 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
504 can specify different directory with --home command line
505 parameter. Affected files irssi/src/silc/core/client_ops.c,
508 * SILC-specific commands aren't now executed if the active server
509 isn't of SILC-type, so there won't be problems with having
510 IRC and SILC protocol support in same client. Affected files
511 irssi/src/silc/core/silc-channels.c, silc-servers.c,
514 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
516 * Improved the signal support in SILC Schedule. Added new
517 function silc_schedule_signal_call which is used by application
518 to mark a signal to be called. It is now safe to perform
519 any kind of tasks in signal callbacks since it is guaranteed
520 that the application specified signal callback is called
521 after the signal is over. Affected files are
522 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
524 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Added `name' field to SilcChannelPrivateKey to represent
527 application given name for the key. Moved also the context from
528 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
529 Added the `name' argument also to the function
530 silc_client_add_channel_private_key.
532 Added function silc_client_current_channel_private_key to set the
533 current channel private key in use.
535 Added "change" command to KEY command which can be used to change
536 the current channel private key. Bound the command also to
539 Also affected files lib/silcclient/client_channel.c,
540 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
542 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
544 * Added silc_rng_get_byte_fast function in to the
545 lib/silccrypt/silcrng.[ch].
547 * Changed the interface of silc_packet_assemble and the
548 silc_packet_send_prepare. If silc_packet_assmble is now
549 called the application does not call silc_packet_send_prepare
550 because the library will call it automatically. These
551 interfaces now also return a reference to the outgoing buffer
552 which includes the assembled packet, which the application can
553 use to encrypt the packet.
555 Affected files are lib/silccore/silcpacket.[ch],
556 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
557 silcd/packet_send.c, server_backup.c and packet_receive.c.
559 * Fixed a packet sending bug on very high load, where outgoing
560 packet queue wasn't handled correctly and packets got corrupted.
561 Affected files are lib/silcutil/*/silc*sockconn.c,
562 lib/silcclient/client.c and silcd/server.c.
564 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
566 * Added macro SILC_PACKET_DATALEN which can be used during
567 packet assembling to check whether the data to be added to
568 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
569 len is truncated until it fits it.
571 Added checks for maximum length of channel message payload and
572 private message payload also.
574 Added checks for maximum packet length in server and in
577 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
578 lib/silcclient/client.c, lib/silccore/silcchannel.c and
579 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
580 lib/silcclient/client_prvmsg.c.
582 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
584 * Added silc_server_packet_queue_purge call to the
585 silc_server_disconnect_remote to assure that all data in the
586 queue before disconnecting is sent to the network. Affected
589 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
591 * Added the deleting of server's own ID cache entry to the
592 silc_server_free function. Free also everything else that
593 has been allocated in silc_server_init. The affected file
596 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
598 * Added functions silc_parse_version_string, silc_version_to_num,
599 and silc_ske_parse_version to parse SILC protocol style version
600 strings. Affected files lib/silcutil/silcutil.[ch] and
601 lib/silcske/silcske.[ch].
603 * Added new configuration params: version_protocol, version_software
604 and version_software_vendor to specify what version the remote
605 host must at least be to be able to connect to server. The vendor
606 string can be regex matched too. Added new function
607 silc_server_connection_allowed to check maximum number of allowed
608 connections, and allowed versions for incoming connections.
609 Affected files are silcd/server.c, server_util.[ch] and
612 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Added preliminary support for signals in scheduler. The
615 signals we care about are now blocked always when the scheduler
616 is locked. This way we can synchronise the use of signal with
617 scheduler. It is guaranteed that when signal occurs the scheduler
618 is not locked, and thus new tasks can be safely added to the
621 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
622 to silc_schedule_internal_init and silc_schedule_internal_uninit.
623 Added new platform specific routines
624 silc_schedule_internal_signals_[un]block and
625 silc_schedule_internal_signal_[un]register.
627 Added new functions to SILC Schedule API:
628 silc_schedule_signal_[un]register. Each signal that application
629 is going to use should be registered to the scheduler.
631 Affected files are lib/silcutil/silcschedule.[ch],
632 lib/silcutil/*/silc*schedule.c.
634 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Check for unauthenticated client and server in the
637 silc_server_new_client and silc_server_new_server functions.
638 Affected file silcd/packet_receive.c.
640 * Added function silc_string_is_ascii to check whether given
641 string is 7-bit ASCII string. Affected files are
642 lib/silcutil/silcutil.[ch].
644 * Added function silc_id_is_valid_server_id into the
645 silcd/serverid.c and added checking for valid Server ID's in
646 silc_server_new_server. The Server ID must always be based
647 on the server's public IP address.
649 * Added logging of DISCONNECT packet message in the server.
650 Affected file silcd/server.c.
652 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Changed all library interfaces that use Global RNG to also
655 accept SilcRng as argument. Affected files are
656 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
657 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
658 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
659 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
662 * Added function silc_pkcs_generate_key to the
663 lib/silccrypt/silcpkcs.[ch] for applications so that they
664 don't need to do pkcs->pkcs->init calls anymore.
666 * Remove SilcSocketConnection from the SFTP API since it really
667 wasn't needed there. The application has the information
668 saved in its contexts anyway and the SFTP layer doesn't need
669 know about it. Affected files lib/silcsft/silcsftp.h and
670 lib/silcsftp/sftp_[server/client].c.
672 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
673 The SilcSimContext is not SilcSim.
675 * Fixed possible buffer overflows in silc_id_render in the
676 lib/silcutil/silcutil.c.
678 * On EPOC the global crypto module lists are not used at all
679 in the crypto library. Added support for using the constant
680 algorithm list on EPOC. Affected files are
681 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
684 * Fixed the handling of third parameter of KICKED notify, since
685 it was mistakenly updated to SILC Protocol 1.0 even though it
686 is to be included in 1.1. Since it is not in 1.0 it is not
687 mandatory, and this fix now handles it only if it is provided,
688 and it is not error if it is not provided. Affected file
689 lib/silcclient/client_notify.c.
691 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
693 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
694 client. Affected file irssi/src/silc/core/client_ops.c.
696 * Merged with Irssi 0.8.4 from irssi.org CVS.
698 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Check for valid socket connection in client entries before
701 sending any messages. Fixes a crash, but doesn't fix some
702 other underlaying bug that is lurking there. Affected
703 file silcd/packet_send.c.
705 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
707 * $usermode, $cumode and $cumode_space expandos shouldn't do
708 anything with non-SILC server records. Affected file
709 irssi/src/silc/core/silc-expandos.c
711 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Fixed the silc_net_check_[host/local]_by_sock to support
714 IPv6 bound sockets as well. Now they can return IPv6 addresses
715 as well. Affected file lib/silcutil/silcnet.c.
717 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
718 Affected lib/silcutil/unix/silcunixnet.c.
720 * Fixed ID rendering (at least on some platforms, not NetBSD)
721 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
723 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Added silc_hash_public_key and silc_hash_public_key_compare
726 functions to be used with SilcHashTable. They can be used to
727 hash public keys and compare public keys in hash table. Affected
728 file lib/silcutil/silcutil.[ch].
730 * Added support for specifying multiple public keys for Client
731 connection section in server configuration file. This makes it
732 possible to accept multiple public keys from same host, or to
733 make a section that accepts any incoming host, and have the
734 accepted public keys listed in the section.
736 Added functions silc_sever_[find/get]_public_key, added the
737 support for this actually to all connection sections but only
738 the Client section is currently allowed to specify multiple
741 Affected files are silcd/server.c, server_internal.h,
742 command.c, protocol.c, server_util.[ch], packet_receive.c.
744 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
746 * Merged Irssi 0.8.2 from irssi.org CVS.
748 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
750 * If silc_debug is TRUE, also output standard logging messages
751 to stderr with the debug output.
753 Made silc_log_reset_all() flushing all channels before returning.
754 Also fixed some documentation typos.
756 Affected files are lib/silcutil/silclog.[ch].
758 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
760 * Fixed the server to check correctly the amount of connections
761 from single host, by checking also the type of the connection.
762 Fixed also the comparison of number of connections and number
763 of allowed connections. Affected files are silcd/server.c,
766 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
768 * Fixed the USERS command reply to save the user's mode on the
769 channel as well. Fixed JOIN command reply to check whether a
770 client is on channel already and not join it twice. Affected
771 file lib/silcclient/command_reply.c.
773 * Added new file silc-expandos.c into irssi/silc/core/ to return
774 various stuff for various signal for the statusbar etc. updating.
775 Now Irssi SILC client prints channel user modes etc. on the
778 * The user mode (like server/router operator changes) is now shown
779 on the Irssi SILC client's statusbar. The affected files are
780 irssi/src/silc/core/client_ops.c, silc-expandos.c.
782 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
784 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
785 to SILC_SCHEDULE_[UN]LOCK macros.
787 * Added more error printing to logs in server code. Affected
788 files silcd/server.c and silcd/protocol.c.
790 * Fixed -S option parsing in Irssi SILC Client. Affected file
791 irssi/src/silc/core/silc-core.c.
793 * Added silc_buffer_alloc_size function. Affected file is
794 lib/silcutil/silcbuffer.h.
796 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
798 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
799 constants. Affected files in
800 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
803 * Changed the internal SFTP Memory FS table to const. Affected
804 file lib/silcsftp/sftp_fs_memory.c.
806 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
808 * Fixed the buffer formatting and unformatting routines to
809 check the size of 64 bits types with sizeof(). Affected
810 file is lib/silcutil/silcbuffmt.c.
812 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
814 * Removed 0.6.x backwards support.
816 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
818 * Changed all integer type names:
819 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
820 to avoid collisions with other libraries using same type names
823 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
825 * Added `prefer_ipv6' argument to the functions
826 silc_net_gethostbyname[_async]. If it is TRUE it will return
827 IPv6 address over IPv4. If FALSE IPv4 address is returned
828 even if IPv6 address was found. Affected files
829 lib/silcutil/silcnet.[ch].
831 * Added support silc_net_create_connection[_async] to fallback
832 to IPv4 address if IPv6 address could not be used (like if
833 it doesn't work on a specific system). Affected file in
834 lib/silcutil/unix/silcunixnet.c.
836 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

842 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
844 * Added automatic extern "C" { ... } for C++ compilers so the
845 application does not need to define them. Affected file
846 includes/silcincludes.h.
848 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
849 old name went against naming convention. Applications now
850 include "silcclient.h" instead of "clientlibincludes.h".
851 Removed includes/clientlibincludes.h, it is redundant now.
853 * Renamed includes/version.h to silcversion.h.
855 * Added really preliminary support for OS/2 into the util
856 library. Only thread & mutex API is implemented, others
857 are still to be implemented. Created the lib/silcutil/os2/
858 directory. Created also file includes/silcos2.h.
860 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
862 * Added preliminary BeOS support into the util library.
863 Created lib/silcutil/beos/, and implemented all the needed
864 functions to support SILC on BeOS. Created also file
867 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
869 * Added proper initializations to silc's irssi code, so it's
870 now possible to load it as module. Affected files
871 irssi/src/silc/core/silc-core.c,
872 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
874 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
876 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into

880 docs from all kinds of filenames. Affected files are
881 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
883 * ROBOdoc documented lib/silcutil/silcmemory.h.
884 Added also new function silc_memdup.
886 * Removed lib/silcutil/silcbufutil.h and moved those routines
887 to the lib/silcutil/silcbuffer.h.
889 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Added `user_count' to the SilcChannelEntry which now tells the
892 number of users on the channel. The user count is now saved
893 in normal server of global channels as well. Affected files
894 silcd/server.c, idlist.h, packet_receive.c and command.c.
896 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
897 include file utility functions.
899 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
900 instead of calling directly OS routines.
902 * Fixed NICK change printing in Irssi SILC Client. Fixed
903 KICKED notify printing in Irssi SILC Client. Affected file
904 irssi/src/silc/core/client_ops.c.
906 * Fixed a NICK change bug in client library, to not recreate the
907 client_entry->channels hash table everytime nick is changed.
908 Affected file lib/silcclient/client.c.
910 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
912 * ROBOdoc documented the lib/silcske/silcske.h, and improved
913 the SKE interface a bit.
915 * Fixed padding problem in PKCS#1. The padding was not actually
916 random since the random number generator was used incorrectly.
917 This security bug affects only when encrypting with PKCS#1, and
918 it is not currently used at all in SILC. SILC only use signing
919 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
921 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
923 * Rewrote the notify handling in Irssi SILC client to not call
924 the events as signals. Fixes problems with Perl support.
925 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
927 * Send the auto-nicking NICK command in client library with
928 little timeout after connecting. The affected file is

931 * Added following new config file settings:
932 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
933 key_exchange_timeout, conn_auth_timeout, connections_max,
936 Implemented all the new config settings handling in the server.
938 Optimized the use of SKE Mutual flag usage. Use it only
939 if connection authentication protocol is not based in public
942 Renamed all SilcServerConfigSection* to SilcServerConfig*
943 to have a bit shorter names.
945 Affected files silcd/serverconfig.[ch], server.[ch], and
948 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
950 * Cleaned up the listening sockets code, preparing for the rehash
951 support. Affected file is silcd/server.c.
953 * Fixed some output messages. Affected files are silcd/silcd.c,
956 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
958 * Create lib/doc/silcrng_intro.html document as introduction
959 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
961 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
963 * Fixes to the silcd config template. Affected file is
964 doc/example_silcd.conf.in.
966 * Removed type casts from silc_calloc(), conforming to the
967 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
969 * Removed param_name member from client, server, and router
970 section structs, now identifying the param directly.
972 Added CONFIG_FREE_AUTH macro in config file parsing.
974 Affected files are silcd/serverconfig.[ch].
976 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
978 * Fixed command line parameter handling. All SILC initialization
979 is now done in silc_core_init() which also fixes autoconnecting
982 Affected files irssi/src/silc/core/silc-core.c,
983 irssi/src/fe-text/silc.c.
985 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * Added new configuration options and blocks:
988 keepalive_secs, reconnect_count, reconnect_interval,
989 reconnect_interval_max, reconnect_keep_trying and
990 require_reverser_lookup. Added ConnectionParam block, and
991 implemented the connection parameters when connecting as
992 initiator and when accepting connections as responder.
994 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
995 whether given configuration value has been given already.
997 Affected files silcd/serverconfig.[c], server.[c].
999 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1000 algorithm parts and created new file silcalgs.conf, that
1001 is now included from the example_silcd.conf.in.
1003 * Optimized the silc_server_connect_to_router_second to take
1004 the connection configuration object from the SilcServerConnection
1005 object instead of finding it during the connecting phase.
1006 Added the configuration object to SilcServerConnection struct.
1007 Affected files silcd/server_internal.h, server.c.
1009 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1011 * Add the client on channel after it was resolved at the
1012 channel message receiving, and it was not already on the
1013 channel. Affected file lib/silcclient/client_channel.c.
1015 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1017 * Fixed the public key authentication to allocate always the
1018 destination signature buffer instead of using static buffer.
1019 Affected file silcd/protocol.c.
1021 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1023 * Unified the serverconfig.[ch]'s helper function interface.
1024 Affected file silcd/serverconfig.[ch].
1026 * Removed doc/example_silc.conf.in since it is redundant.
1027 The make install will now install irssi/silc.conf file.
1029 * Added new Passphrase and Publickey authentication methods to
1030 config file, allowing both public key and passphrase based
1031 authentication to be set at the same time.
1033 Added `prefer_passphrase_auth' setting in config file which
1034 can be used to set to prefer passwd auth if both passwd and
1035 public key is set. If not set, public key is preferred.
1036 This has effect only when being initiator (responder will try
1039 Added support for authentication with passphrase and public key
1040 at the same time. The passphrase is tried first always since
1041 it is faster to check.
1043 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1045 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1047 * Merged the new SILC Config library, with the server parsing
1048 support. Read the header file silcconfig.h or the toolkit
1049 documentation for the news. Affected files are
1050 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
1051 silcd/command.c silcd/packet_receive.c silcd/packet_send.c

1055 * Fixed some silclog documentation. Affected file is
1056 lib/silcutil/silclog.h.
1058 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1060 * The silc_cipher_register, silc_hash_register and
1061 silc_hmac_register now checks if the object to be registered
1062 is registered already. Affected files are
1063 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1065 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1067 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

1071 * Allow zero length channel messages inside the Channel Message
1072 Payload. Affected file lib/silccore/silcchannel.c.
1074 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1075 as header filenames.
1077 * Removed lib/silcclient/README and created HTML file
1078 lib/silcclient/silcclient_using.html, which is now included
1079 as part of Toolkit documentation.
1081 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1083 * Fixed CUMODE_CHANGE notify handling to change the mode of
1084 correct client. Affected file lib/silcclient/client_notify.c.
1086 * Make silc_rng_alloc fail if it cannot allocate the sha1
1087 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1089 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1091 * Fixed the file transfer's key agreement payload to include
1092 zero port also if the hostname is NULL because it could not
1095 Call file transfer monitor callback now also if error occurs
1096 during key agreement protocol.
1098 Changed the silc_client_file_send interface to return the
1099 SilcClientFileError instead of session id. The session ID
1100 is returned into pointer provided as argument.
1102 Check that the file exists locally before sending the
1103 file transfer request at all.
1105 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1107 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1108 error than can occur while key agreement protocol. Affected
1109 file lib/silcclient/silcapi.h.
1111 * Fixed the event_mode CMODE handler to not crash when mode
1112 is changed and +k mode is set in the channel. Affected file
1113 irssi/src/silc/core/silc-channels.c.
1115 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1116 SILC_LOG_WARNING to give out Warning and not Error. Affected
1117 file lib/silcutil/silclog.c.
1119 * Fixed the channel message payload decryption in the function
1120 silc_channel_message_payload_decrypt to not modify the original
1121 buffer before it is verified that the message decrypted
1122 correctly. Otherwise, next time it is called with correct
1123 channel key it won't encrypt since the payload is corrupted.
1124 Affected file lib/silccore/silcchannel.c.
1126 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1128 * Do not constantly resize the window. A fix patch by cras.
1129 Affected file irssi/src/fe-text/screen.c.
1131 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1134 Affected file lib/silcutil/silcnet.c.
1136 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * Fixed a bug in hash table internal routine for traversing
1139 the table with foreach callback. The current entry may
1140 become invalid in the callback but it was referenced after
1141 the callback returned.
1143 Do not allow auto rehashing of hash table during the
1144 silc_hash_table_foreach operation, for same reasons as it is
1145 not allowed for SilcHashTableList. Affected files are
1146 lib/silcutil/silchashtable.[ch].
1148 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1150 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1151 Win32 DLL. extern's in header files are now declared with
1154 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1156 * Fixed private message handling. It used some old code that
1157 caused the client to crash. Affecte file is
1158 lib/silcclient/client_prvmsg.c.
1160 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Added function silc_client_add_channel,
1163 silc_client_replace_channel_id, and removed functions
1164 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1165 from client library.
1167 * Added cross reference of the joined channels to the
1168 SilcClientEntry, and changed the SilcChannelEntry's
1169 users list to SilcHashTable. The affected files are
1170 lib/silcclient/idlist.[ch].
1172 * Fixed a bug in hash table tarversing. While the hash table
1173 is traversed with SilcHashTableList the table must not be
1174 rehashed. It is now guaranteed that auto rehashable tables
1175 are not rehashed while tarversing the list. Also defined that
1176 silc_hash_table_rehash must not be called while tarversing
1177 the table. Added function silc_hash_table_list_reset that must
1178 be called after the tarversing is over. The affected files are
1179 lib/silcutil/silchashtable.[ch].
1181 * Changed all hash table traversing to call the new
1182 silc_hash_table_list_reset in server and in client library.
1184 * Added function silc_client_on_channel to return the
1185 SilcChannelUser entry if the specified client entry is joined
1186 on the specified channel. This is exported to application as
1187 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1189 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed founder regaining problem with JOIN command on normal
1192 server. The notify for mode change must be sent always and
1193 not only if !cmd->pending. Affected file silcd/command.c.
1195 * Fixed the WHOWAS command's reply sending to support the
1196 lists correctly. Affected file silcd/command.c.
1198 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * When sending JOIN command to router for processing the
1201 sender's old command identifier was not saved back to the
1202 sender's command context, fixed now. The affected file is
1205 * Create the key in JOIN command of the router did not return
1206 the channel key, added check for this. Affected file is
1209 * Fixed a channel ID update bug in JOIN command reply. Do
1210 not directly upgrade the ID but call the function
1211 silc_idlist_replace_channel_id if the ID was changed.
1212 Affected file silcd/command_reply.c.
1214 * Fixed memory leaks from command calling if it would fail.
1215 Affected file silcd/command.c.
1217 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1219 * Applied patches from cras:
1221 Memory leak fixes around libaries, irssi window resize fix,
1222 new silclist.h and silcdlist.h, all extern inline changed to
1225 * Removed dotconf from lib/dotconf, not needed anymore.
1227 * Removed TRQ from lib/trq, not needed anymore.
1229 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1230 with server connections. Later this will be configurable
1231 in config file after new config file is done. Affected file
1234 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1236 * Fixed a crash in server related to channel announcements.
1237 Affected file silcd/server.c.
1239 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1241 * Fixed memory leaks in silc_server_create_new_channel*
1242 functions. Affected file silcd/server.c.
1244 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1245 which ID was changed. This way the router will send the
1246 user list for the channel again, and server won't be in
1247 desync in some rare circumstances. Affected file is
1248 silcd/packet_receive.c.
1250 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1252 * Check for NULL socket pointer in the function
1253 silc_server_packet_send_to_channel_real. Affected file
1254 silcd/packet_send.c.

1257 list. Affected file silcd/packet_receive.c.
1259 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Fixed some header addition to Toolkit distribution in
1262 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1264 * Added lib/silcclient/client_ops_example.h as an template
1265 file for application programmers to quickly start using
1266 the SilcClientOperation functions in their application.
1267 Updated the lib/silcclient/README as well to tell about this
1268 nice file made available.
1270 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Call silc_server_remove_from_channels when removing client
1273 entry when NO_SUCH_CLIENT_ID was received. Affected file
1274 is silcd/command_reply.c.
1276 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1278 * Added server & router operator statistics updating. Affected
1279 file silcd/packet_receive.c and silcd/command.c.
1281 * Fixed the SERVER_SIGNOFF notify handling on normal server
1282 not to save the history information for clients. Same was
1283 fixed earlier in remove_clients_by_server function, but not
1284 here. Affected file silcd/packet_receive.c.
1286 * Raised the default connection-retry count from 4 to 7 in
1287 server. Affected file silcd/server.h.
1289 * Cancel any possible reconnect timeouts when we start the
1290 key exchange. Affected file silcd/server.c.
1292 * Do not reconnect on connection failure when SCONNECT was
1293 given. Affected files silcd/server.[ch].
1295 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1297 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1299 * Fixed the NICK command to always give the unformatted
1300 nickname to the one giving the NICK command. If unformatted
1301 nickname is cached already it will be formatted and the
1302 local entry will always get the unformatted nickname.
1303 Affected file lib/silcclient/idlist.c.
1305 * Fixed some double frees from client library commands.
1306 Affected file is lib/silcclient/command.c.
1308 * Fixed CUMODE command in server to assure that no one can
1309 change founder's mode than the founder itself, there was a
1310 little bug. Affected file silcd/command.c.
1312 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1314 * Removed the SilcClientCommandDestructor from the client
1315 libary, it is not needed anymore. Affected files are
1316 lib/silcclient/silcapi.h, command[_reply].[ch],
1317 client_notify, idlist.c.
1319 * Fixed GETKEY command to first resolve client, and then
1320 resolve the server only if the client was not found, instead
1321 of resolving both at the same time. Affected file is
1322 lib/silcclient/command.c.
1324 * Added silc_client_start_key_exchange_cb and lookup the
1325 remote hostname and IP address before starting the key
1326 exchange with server. The affected file is
1327 lib/silcclient/client.c.
1329 * The server's public key is now saved using the IP address
1330 of the server and not the servername for the filename.
1331 The hostname public key filename is checked as an fall back
1332 method if the IP address based filename is not found.
1334 Fixed the GETKEY command to save the fetched server key
1335 in correct filename.
1337 Print the remote server's hostname now when new key is
1338 received during connection process. Affected file is
1339 irssi/src/silc/core/client_ops.c.
1341 * Return always our own public key to the client if it asks
1342 for it with GETKEY command. Affected file silcd/command.c.
1344 * Removed the use_auto_addr variable from default config
1345 file since it was in wrong section. Affected file is
1348 * Fixed TOPIC_CHANGE notification to not route it when it
1349 was sent using silc_server_send_notify_to_channel function.
1350 Affected file silcd/command.c.
1352 * Fixed silc_server_send_notify_kicked to send the kicker's
1353 Client ID also, it was missing. Affected files are
1354 silcd/command.c, silcd/packet_send.[ch].
1356 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1358 * Do not save client history information in SERVER_SIGNOFF.
1359 Fixes the bug in normal server that it does not detect
1360 the client becoming valid after the server becomes back
1361 online. Affected file silcd/server_util.c.
1363 * Added `sock_error' field into the SilcSocketConnection
1364 context. When error occurs during socket operation (read
1365 or write) the error is saved. Added also new function
1366 silc_socket_get_error to return human readable socket error
1367 message. Affected files are lib/silcutil/silcsockconn.[ch],
1368 lib/silcutil/unix/silcunixsockconn.c, and
1369 lib/silcutil/win32/silcwin32sockconn.c.
1371 * The server now prints the socket error message in the
1372 signoff for client. Affected file silcd/server.c.
1374 * Fixed the `created' channel information sending from router
1375 to server in JOIN command. Checks now whether the channel
1376 really was created or not and set it according that.
1378 Fixed the JOIN command to use the client entry's current
1379 ID during the joining procedure instead of the one it sent
1380 in the command (it is checked though), since it can change
1381 between the packet processing and command processing, and
1382 would just case unnecessary pain in the client end. Affected
1383 file silcd/command.c.
1385 * Fixed a channel key payload sending to use correct channel
1386 ID when the server was forced to change the channel's ID by
1387 router. Router sent the key payload with the old Channel ID.
1388 Affected file silcd/packet_receive.c.
1390 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1392 * Call silc_server_save_channel_key only if the key payload
1393 was provided in the JOIN command's command reply. Affected
1394 file silcd/command_reply.c.
1396 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1398 * Fixed silc_mp_sizeinbase to return the value correctly with
1399 MPI. Affected file lib/silcmath/mp_mpi.c.
1401 * Fixed the stop_server signal to correctly stop the scheduler
1402 and gracefully stop the server when SIGTERM or SIGINT signals
1403 are received. Affected file silcd/silcd.c.
1405 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1407 * Simple handling of TERM and HUP signals. Also added some log
1408 flushing call around. Affected file is
1411 * Fixed small bugs in silclog.c. Now buffering output will take
1412 effect after 10 seconds since startup: This will ensure that
1413 no important startup messages are lost. Also output redirection
1414 will preserve original format ([Date] [Type] message).
1415 Affected file is lib/silcutil/silclog.c.
1417 * Added two options to the config file, in the logging section:
1418 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1419 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1421 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1423 * Do not print the warning about log files not being initialized
1424 more than once to avoid excess logging. Affected file is
1425 lib/silcutil/silclog.c.
1427 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1428 the SIM copying in make install in Makefile.am.pre.
1430 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1432 * Rewritten silclog APIs. Globally interesting changes follows:
1433 silc_log_set_files() changed to silc_log_set_file().
1434 silc_log_set_callbacks() changed to silc_log_set_callback().
1435 ROBOdoc documented silclog header file.
1436 SilcLogCb now returns bool to wether inihibit the default
1437 handler or not (to keep the old behaviour return always TRUE).
1438 The new APIs should also fix the problem of the
1439 silcd_error.log file that was written in the current directory.
1442 Log files streams will remain opened after silc_log_set_file()
1443 call, means less CPU usage notably on high traffic servers.
1444 File streams are now full buffered, and flushed to the disk
1445 every 5 minutes, lesses HD activity and CPU usage.
1446 Messages can be redirected, allowing admins to configure
1447 one single logfile for all server messages.
1448 the silc_log_quick global variable to activate fast-logging.
1449 Affected files lib/silcutil/silclog.[ch]
1451 * Changed some code to conform new silclog APIs. Affected
1452 files are doc/example_silcd.conf.in, silcd/server.c
1453 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1456 * Fixed a memory leak that could occur in some situations.
1457 Affected file silcd/serverconfig.c.
1459 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1461 * Added the silc_client_del_client to remove the client from
1462 all channels as well. Affected file lib/silcclient/idlist.c.
1464 * Fixed the client library to correctly remove the client
1465 from all channels when the client entry is being destroyed.
1466 Affected file lib/silcclient/client_notify.c, command.c.
1468 * Added auto-nicking support to the client library. If the
1469 applicatio now sets client->nickname it will be sent to the
1470 server after connecting by the library. This way for example
1471 SILCNICK (or IRCNICK) environment variables will have effect
1472 and always change the nickname automatically to whatever
1473 it is wanted. Affected file lib/silcclient/client.[ch].
1475 * Renamed silc_server_command_bad_chars to the
1476 silc_server_name_bad_chars and moved it to the
1477 silcd/server_util.[ch]. Added also new function
1478 silc_server_name_modify_bad to return nickname that
1479 includes bad characters as new nickname without those
1480 bad characters. This check and modify is now used in
1481 silc_server_new_client when the username is initially set
1482 as nickname, so it must be checked to be valid nickname.
1483 Affected file silcd/packet_receive.c.
1485 * The nickname length is now taken from the packet for real
1486 and not trusted to strlen() since it clearly can return
1487 wrong length for nickname including bad characters. This
1488 also applies to channel names. Affected file silcd/command.c.
1490 * Removed the lib/silcsilm/modules directory. Modules are now
1491 compiled into the lib/silcsim. Fixed the copying of the
1492 modules to follow symbolic links in Makefile.am.pre.
1494 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1496 * Fixed silc_string_regexify list creation. Fixes bugs with
1497 BAN and INVITE commands in server. The affected file is
1498 lib/silcutil/unix/silcunixutil.c.
1500 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Removed the command destructor entirely from the server's
1503 command and command reply routines. It is not needed, and
1504 its usage was buggy and caused crashes. Affected files are
1505 silcd/command[_reply].[ch].
1507 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Cancel protocol and NULL sock->protocol if timeout
1510 occurred during protocol. Affected file silcd/server.c.
1512 * Cancel protocol timeouts always before calling the final
1513 callback, to assure that after final callback is called
1514 no other state will be called for the protocol anymore.
1515 Affected file silcd/protocol.c.
1517 * Print error log if incoming connection configuration could
1518 not be found. Affected file silcd/server.c.
1520 * Fixed JOIN command to correctly save the founder mode
1521 to the client on normal SILC server, when the channel
1522 was created by the router. Affected file silcd/command.c.
1524 * Fixed LIST command (hopefully) to send correct reply
1525 packets. Affected file silcd/command.c.
1527 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1529 * The silc_packet_receive_process now returns FALSE if the
1530 read data was invalid packet, and TRUE if it was ok.
1532 The server now checks that if unauthenticated connection
1533 sends data and its processing fails the server will close
1534 the connection since it could be a malicious flooder.
1536 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1538 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1540 * Make sure the warning about error opening a log file is
1541 printed only once and not everytime it fails (produces
1542 too much useless log). Affected file lib/silcutil/silclog.c.
1544 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1546 * Made the silc_server_daemonise() function more readable.
1547 Affected file silcd/server.c.
1549 * Pid file is now optional, the user may comment it out from
1550 the config file. Removed define SILC_SERVER_PID_FILE, we
1551 don't need a default any longer. Affected file
1552 configure.in.pre, lib/Makefile.am.pre.
1554 * Make some use of the pid file. The server now dies at startup
1555 if it detects a valid pid file on his path. The server would
1556 die anyway in this circumstance, because of the bind() failure.
1557 Affected file silcd/silcd.c.
1559 * No longer compiling lib/dotconf.
1561 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Fixed JOIN command parsing not to crash. Affected file
1564 lib/silcclient/command.c.
1566 * Fied the NICK_CHANGE notify to add the new client entry
1567 even it is resolved. This removes an <[unknown]> nick
1568 thingy bug in the client. Affected file is
1569 lib/silcclient/client_notify.c.
1571 * Do not try to allocate 0 bytes (efence does not like it)
1572 in lib/silccore/silccomand.c when encoding payload.
1574 * Do not take IRCNICK as nickname in Irssi SILC client since
1575 it is not possible to set nickname before hand connecting
1576 the server (TODO has an entry about adding auto-nicking
1579 * Changed the silc_server_command_pending to check whether
1580 there already exists an pending entry with the specified
1581 command, command identifier and pending callback. This is
1582 to fix IDENTIFY and WHOIS related crashes that may register
1583 multiple pending commands with same identifier. Affected
1584 file silcd/command.c.
1586 * Fixed the server to reconnect to the router even if it
1587 was already reconnecting and EOF was received. This to
1588 fix a possibility that the server wouldn't ever try to
1589 auto-reconnect to the router. Affected file silcd/server.c.
1591 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Fixed the server's password authentication to use the
1594 length of the locally saved password, and not the one
1595 sent in the packet. Affected file silcd/protocol.c.
1597 * Fixed same password authentication problem in the
1598 Authentication Payload handling routines in
1599 lib/silccore/silcauth.c.
1601 * Yet another password authentication problem fixed with
1602 channel password handling in silcd/command.c.
1604 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * If first character of string in silc_parse_userfqdn is '@'
1607 then do not parse it. Affected file is
1608 lib/silcutil/silcutil.c.
1610 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * Fixed minor bug in IDENTIFY command reply sending, which
1613 caused various weird problems during JOIN when it was
1614 resolving names for users. Affected file silcd/command.c.
1616 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Fixed the IDENTIFY command reply sending to chech better valid
1619 clients. It was possible to send incomplete list of replies.
1620 Affected file silcd/command.c.
1622 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Added silc_client_command[s]_[un]register functions now to
1625 dynamically register the commands in client library. Removed
1626 the static table of commands. This allows the client library
1627 to call commands without causing the application to know about
1628 what commands library has called.
1630 Removed the INFO command reply kludge to detect when the command
1631 was called by library. Now library use its own command reply
1632 function for INFO command.
1634 Added function silc_client_command_call to call a command.
1635 Application can use it to call command, not access the structure
1638 Now all commands that are sent by the client library (not
1639 explicitly sent by application) use own command reply functions.
1641 Affected files around lib/silcclient/ and in
1642 irssi/src/silc/core/.
1644 * Fixed the WHOIS command reply sending to chech better valid
1645 clients. It was possible to send incomplete list of replies.
1647 Fixed the WHOIS and IDENTIFY to send the request to router
1648 if normal server did not do it and did not find any results.
1650 Affected file silcd/command.c.
1652 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Moved the internal data from SilcClient context into its
1655 own file, not accesible to application. Affected files
1656 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1657 and other files in client library.
1659 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * Added doc/examples installation target in Makefile.am.pre.
1664 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1667 commands the found client entry will be removed from the
1668 cache, after notifying application about the error. Affected
1669 file lib/silcclient/command_reply.c.
1671 * Changed the /MSG to check for exact nickname user gave, and
1672 not let `nick' match `nick@host' if it is only one found. Now,
1673 user must type the exact nickname (like nick@host2) even if
1674 there are no more than one same nicks found. This is to avoid
1675 a possibility of sending nickname to wrong nickname since
1676 `nick' could match `nick@host'. Affected file is
1677 irssi/src/core/silc-servers.c.
1679 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Do not print "you are now server operator" or similar when
1682 giving /away command. Affected files are
1683 irssi/src/silc/core/client_ops.c, silc-servers.h.
1685 * Made the silc_server_command_pending_error_check to send
1686 the same command reply payload it received back to the
1687 original sender of the command. This way all arguments
1688 that was received by the server will be received by the
1689 client too. Affected file silcd/command.c.
1691 * Added the silc_idcache_add to return the created cache entry
1692 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1694 * Add global clients to expire if they are not on any channel.
1695 This is because normal server will never know if they signoff
1696 if they are not on any channel. The cache expiry will take
1697 case of these entries. This is done by normal servers only.
1698 The affected files are silcd/command_reply.c,
1699 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1701 * If server receives invalid ID notification for WHOIS or
1702 IDENTIFY and the ID exists in the lists, it is removed.
1703 Affected file silcd/command_reply.c.
1705 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1706 in client then client entry that it matches is searched and
1707 the nickname is printed on the screen for user. Affected
1708 file irssi/src/silc/core/client_ops.c.
1710 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Use cache entry expire time in the LIST command reply to
1713 purge old entries from the cache after the LIST command
1714 reply has been received. This way we don't have non-existent
1715 entries in the cache for too long. Affected file is
1716 silcd/command_reply.c.
1718 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * If we are normal server, and we've not resolved client info
1721 in WHOIS or IDENTIFY from router, and it is global client,
1722 we'll check whether it is on some channel. If it is not
1723 then we cannot be sure about its validity and will resolve it
1724 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1725 file silcd/command.c.
1727 * Search channel by name (if possible) rather than by ID
1728 in IDENTIFY command's command reply. Affected file is
1729 silcd/command_reply.c.
1731 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1734 Updated specs and implemented it. Affected file silcd/command.c,
1735 silcd/packet_send.c and silcd/packet_receive.c.
1737 * Implemented the <founder auth> payload handling in the JOIN
1738 command. If provided all conditions for channel joining
1739 except requirement to provide correct passphrase can be
1740 overrided by the channel founder. Updated the protocol specs.
1741 Affected file silcd/command.c.
1743 Added support for founder auth in JOIN command in client
1744 library. Fixed the parsing of the JOIN command now to support
1745 all options as they should be. The affected file is
1746 lib/silcclient/command.c.
1748 * Optimized the WHOIS and IDENTIFY commands to send the request
1749 to router only if it includes nicknames or other names. If
1750 they include only IDs then check the local cache first before
1751 routing. Affected file is silcd/command.c.
1753 * Added channels topic announcements. Affected file is
1754 silcd/packet_receive.c and silcd/server.c.
1756 * Fixed the silc_server_send_notify_topic_set to really destine
1757 the packet to channel. Affected file silcd/packet_send.c.
1759 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1760 library. Affected file lib/silcclient/client_notify.c.
1762 * Added UMODE announcements. Affected file silcd/server.c.
1764 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Memory leak fixes in:
1768 lib/silcutil/silcsockconn.c
1769 lib/silcske/silcske.c
1770 lib/silcske/groups.c
1772 lib/silccrypt/silcpkcs.c
1773 lib/silccore/silccommand.c
1774 lib/silccore/silcidcache.c
1779 * ROBOdoc documented the lib/silcske/groups.h file and a
1780 bit changed the interface for better.
1782 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1784 * Update the client entry context in the ID cache after
1785 nick change. Affected file lib/silcclient/command.c.
1786 Fixes the CUMODE command when regaining founder privileges,
1787 and a little WHOIS problem.
1789 * Fixed silc_net_gethostbyname to correctly call the
1790 inet_ntop. Affected file lib/silcutil/silcnet.c.
1792 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1794 * Added IPv6 support checking to the configure.in.pre, added
1795 also --enable-ipv6 option to override the check. Affected
1796 file configure.in.pre.
1798 * The silc_thread_create now calls the start function
1799 directly if threads support is not compiled in. Removes
1800 ugly #ifdef's from generic code. Affected files are
1801 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1803 * Added silc_net_gethostby[name/addr]_async to asynchronously
1804 resolve. Affected files are lib/silcutil/silcnet.[ch].
1806 * Added support for rendering IPv6 based server, client and
1807 channel IDs. Affected file lib/silcutil/silcutil.c.
1809 * Added support for creating IPv6 based server IDs. Affected
1810 file is silcd/serverid.c.
1812 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1814 * Added silc_net_gethostby[addr/name] into the
1815 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1816 routines. Added silc_net_is_ip[4/6]. Affected file is
1817 lib/silcutil/unix/silcunixnet.c. All routines that take
1818 address as argument now supports both IPv4 and IPv6 addresses.
1820 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1822 * Fixed LIST command reply sending in server. Affected file
1825 * Server now sends the kicker's client ID in the KICK notify
1826 to the kicked client. Affected file silcd/command.c.
1828 * The client library now parses the kickers client ID and
1829 UI displays it. Affected files lib/silcclient/client_notify.c
1830 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1832 * Made all payload parsing function prototypes consistent.
1833 They all take now const unsigned char * and uint32 pair as
1834 the payload data instead of SilcBuffer. Changes all around
1835 the source tree. Other unsigned char* -> const unsigned char*
1836 changes around the tree as well.
1838 * Optimized SFTP client and server packet sending not to
1839 allocate new buffer for each packet but to recycle the
1840 first allocated buffer. Affected files are
1841 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1843 * Optimized the SFTP client to use SilcList instead of
1844 SilcDList for requests, because it is faster. Affected file
1845 is lib/silcsftp/sftp_client.c.
1847 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1848 into lib/silccore/silcid.[ch].
1850 Renamed silcpayload.[ch] into silcargument.[ch].
1852 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * If client entry is deleted with active key agreement
1855 session, abort the session.
1857 The silc_client_abort_key_agreement now calls the completion
1858 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1860 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1863 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Don't use __restrict in older GCC's. Affected file is
1866 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1868 * silc_net_localhost now attempts to reverse lookup the
1869 IP/hostname. Affected file lib/silcutil/silcnet.c.
1871 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1872 command. It can be used to gain founder privileges at
1873 the same time when joining the channel.
1875 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1876 kicker's client ID as well. Updated protocol specs.
1878 Defined that the server must send SILC_COMMAND_IDENTIFY
1879 command reply with error status to client who sent
1880 private message with invalid client ID.
1882 Updated the protocol specification.
1884 * Added silc_server_send_command_reply to send any
1885 command reply. Affected file silcd/packet_send.[ch].
1887 * Added silc_id_payload_encode_data to encode ID payload
1888 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1890 * The server now send IDENTIFY command reply with error
1891 status if client ID in private message is invalid. Affected
1892 file silcd/packet_receive.c.
1894 * Save the server key file with server's IP address in
1895 the filename instead of hostname. The affected file is
1896 irssi/src/silc/core/client_ops.c.
1898 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1903 * Added libtool support for compiling shared objects in
1904 lib/silcsim. Affected file configure.in.pre and
1905 lib/silcsim/Makefile.am. Original patch by cras.
1907 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Pid file configuration, and server's config file fixes
1910 patch by toma. Updated CREDITS file.
1912 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Fixed silc_client_channel_message to not try to decrypt
1915 the message twice if it resolved the destination client
1916 information. This could cause of dropping one channel
1917 message. Affected file lib/silcclient/client_channel.c.
1919 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1921 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1922 lib/silcclient/client.c. This function is used when the SILC
1923 Client is run under some other scheduler, or event loop or
1924 main loop. On GUI applications, for example this may be
1925 desired to used to run the client under the GUI application's
1926 main loop. Typically the GUI application would register an
1927 idle task that calls this function multiple times in a second
1928 to quickly process the SILC specific data.
1930 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1932 * Fixed silc_server_drop() for dropping the supplementary
1933 groups as well, this could cause a security hole on some
1936 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1941 * Write PID file after dropping privileges. Added -F option
1942 to run server on foreground. A patch by debolaz.
1943 Affected files silcd/server.c, silcd/silcd.c.
1945 * Fixed MOTD to return the MOTD file server name. Affected
1946 file silcd/command.c.
1948 * Added INFO command reply handling to the Irssi SILC Client.
1949 Affected file irssi/src/silc/core/client_ops.c.
1951 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Fixed the silc_idcache_list_* routines to really support
1954 the dynamic list. Fixes a crash. Affected file is
1955 lib/silccore/silcidcache.c.
1957 * Fixed the LIST command reply to really call LIST command's
1958 pending callbacks. Affected file silcd/command_reply.c.
1960 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Update conn->local_entry->nickname after giving NICK
1963 command. Affected file lib/silcclient/command.c.
1965 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1967 * Added the [pid] option to the silcd configuration file
1969 Affected files: serverconfig.[ch] and silcd.c
1971 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Save fingerprint in WHOIS command reply in server.
1974 Affected file silcd/command_reply.c.
1976 * Fixed NICK commands pending callback registration.
1977 Affected file lib/silcclient/command.c.
1979 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Use ++server->cmd_ident when sending commands in server,
1982 instead of random number. Affected file silcd/command.c.
1984 * Fixed GETKEY command reply to call actually GETKEY pending
1985 command callbacks. Affected file silcd/command_reply.c.
1987 * A bit stricter check for nicknames. Check for same nickname
1988 in NICK command also. Affected file silcd/command.c.
1990 * Do not call INFO command everytime client ID changes, only
1991 during first connecting. Affected file lib/silcclient/client.c.
1993 * Set the new nickname only after successful command reply for
1994 NICK command is returned by server. Affected file
1995 lib/silcclient/command.c.
1997 * Remove nicknames from nicklist during server_signoff notify.
1998 Should fix /NAMES bit more. The affected file is
1999 irssi/src/silc/core/silc-channels.c.
2001 * Added `fingerprint' field to the SilcIDListData in the
2002 silcd/idlist.h to hold the fingerprint of the client's
2005 Send the fingerprint of the client's public key in WHOIS
2008 Affected files silcd/command.c, and silcd/idlist.[ch].
2010 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2011 create fingerprint from given data.
2013 * Show the fingerprint of the client's public key in WHOIS.
2014 Affected files irssi/src/module-formats.[ch] and
2015 irssi/src/silc/core/client_ops.c.
2017 * Format the multiple same nicknames also during JOIN and
2018 NICK_CHANGE notifys. Affected file is
2019 lib/silcclient/client_notify.c.
2021 * Do not print error on screen for invalid private message
2022 payload since it can come if someone is sending private
2023 messages with wrong key. Affected file
2024 lib/silccore/silcprivate.c.
2026 * Fixed multiple concurrent /PING crash. Affected file
2027 lib/silcclient/command.c.
2029 * Changed the wrong ID encoding. All IP addresses must be
2030 in MSB first order in encoded format. They were encoded
2031 wrong and was in LSB format. Affected files are
2032 silcd/serverid.c, lib/silcutil/silcutil.c.
2034 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2036 * Call the `connect' client operation through the scheduler
2037 in case of error. Affected file lib/silcclient/client.c.
2039 * Call the `failure' client operation even if the error
2040 occurred locally during a protocol. Affected file is
2041 lib/silcclient/protocol.c.
2043 * Added support of sending LIST command to router from normal
2044 server. This way normal server can get list of all channels
2045 in the network too. Fixed the channel list sending in the
2046 server too. Affected files are silcd/command.c, and
2047 silcd/command_reply.[ch].
2049 * Added silc_server_update_channels_by_server and
2050 silc_server_remove_channels_by_server. They are used during
2051 disconnection of primary router and in backup router protocol.
2052 Affected file silcd/server_util.[ch], silcd/server.c and
2053 silcd/server_backup.c.
2055 * Fixed channel adding to global list in IDENTIFY command
2056 reply in server. Affected file silcd/command_reply.c.
2058 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * If the incoming packet type is REKEY or REKEY_DONE process
2061 that packet always synchronously. Fixes yet another MAC
2062 failed error on slow (dialup) connections. Affected file
2063 lib/silcclient/client.c and silcd/server.c.
2065 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Call check_version SKE callback for initiator too. Affected
2068 file lib/silcske/silcske.c.
2070 * Implemented fix for security hole found in the SKE that was
2071 fixed in the specification few days back; the initiator's
2072 public key is now added to the HASH value computation.
2073 Added backwards support for the old way of doing it too, for
2074 old clients and old servers. Affected file is
2075 lib/silcske/silcske.c.
2077 * Enabled mutual authentication by default in SKE. If initiator
2078 is not providing mutual authentication the responder will
2079 force it. This will provide the proof of posession of the
2080 private key for responder. The affected files are
2081 lib/silcclient/protocol.c and silcd/protocol.c.
2083 * Do not cache anymore the server's public key during SKE.
2084 We do mutual authentication so the proof of posession of
2085 private key is done, and if the server is authenticated in
2086 conn auth protocol with public key we must have the public
2087 key already. Affected file silcd/protocol.c.
2089 * Added new global debug variable: silc_debug_hexdump. If
2090 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2091 file lib/silcutil/silclog.[ch].
2093 * Fixed compilation warning due to char * -> const char *.
2094 Affected files lib/silcutil/silcnet.h, and
2095 lib/silccore/silcauth.[ch].
2097 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Fixed CMODE command when new channel key was created. If
2100 the creation failed the old key was removed. Next time giving
2101 same command would crash the server since the old key was
2102 freed already. Affected file silcd/command.c.
2104 * Fixed the silc_server_announce_get_channels to not crash
2105 on reconnect. Affected file silcd/server.c.
2107 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Added silc_log_set_debug_string function to set a regex
2110 string to match for debug output. Only the function names,
2111 or filenames matching the given debug string is actually
2112 printed. This way it is possible to filter out those debug
2113 strings that user is not interested in.
2115 Fixed a bug in silc_string_regexify.
2117 Affected files lib/silcutil/silclog.[ch], and
2118 lib/silcutil/unix/silcunixutil.c.
2120 * Changed the -d options in both server and Irssi SILC client
2121 to take the debug string as argument. Affected files
2122 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2124 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * Added silc_hash_babbleprint to create a Bubble Babble
2127 Encoded fingerprint. The encoding is developed by Antti
2128 Huima (draft-huima-babble-01.txt), and it creates human
2129 readable strings out of binary data. Affected file
2130 lib/silccrypt/silchash.[ch].
2132 * Print the babble print now in addition of fingerprint as well
2133 in Irssi SILC client. Affected files are
2134 irssi/src/fe-common/silc/module-formats.[ch],
2135 irssi/src/fe-common/silc/core/client_ops.c.
2137 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Fixed a security problem found in SKE. The initiator's
2140 public key too is now added to the HASH hash value creation
2141 which is signed by the responder to create the SIGN value.
2142 This will prevent anyone in the middle to lie to the responder
2143 about the initiator's public key. If this is done now, the
2144 man in the middle will get caught. Updated the protocol
2147 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Better installation directory handling. Configure module
2150 paths and other paths automatically to example_silc* files
2151 in doc/. A patch by toma.
2153 * Fixed compiler warning from MPI library, and from SILC RNG.
2156 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2157 It can be configured with ./configure. A patch by toma.
2159 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Find correct make to use in prepare-clean. A patch by
2162 toma. Affected file prepare-clean.

2181 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * Added silc_pkcs_public_key_compare to compare two
2184 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2186 * Check that the client who set the founder mode on the
2187 channel is the same client that is giving the founder
2188 mode to itself. It is done by comparing the saved public
2189 key (it is saved even in the authentication is passphrase).
2190 Affected file silcd/command.c.

2197 * Process the DISCONNECT packet through scheduler in the
2198 client library. Affected file lib/silcclient/client.c.
2200 * Fixed the silc_client_packet_parse to not to increase
2201 the packet sequence number if the conn->sock and the
2202 current socket connection is not same. This can happen
2203 for example during key agreement when the conn includes
2204 multiple socket connections (listeners). Affected file
2205 lib/silcclient/client.c.
2207 * The sender of the file transfer request now provides also
2208 the pointer (listener) for the key exchange protocol. If
2209 the listener cannot be created then it sends empty key
2210 agreement and lets the receiver provide the listener.
2212 Added `local_ip' and `local_port' arguments to the
2213 silc_client_file_send. If they are provided they are used,
2214 if not then it will attempt to find local IP address, if
2215 not found or bind fails then the remote client will provide
2218 Affected files are lib/silcclient/client_ftp.c and
2219 lib/silcclient/silcapi.h.
2221 * Extended the FILE SEND command to support defining the
2222 local IP and port for key exchange listener. They are
2223 optional. Affected file irssi/src/silc/core/silc-servers.c.
2225 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Defined to WHOIS command reply the sending of fingerprint
2228 of the client's public key (if the proof of posession of the
2229 corresponding private key is verified by the server).
2230 Updated to the protocol specification.
2232 * Added support of receiving the client's public key's
2233 fingerprint in command reply in client library. Affected
2234 file is lib/silcclient/command_reply.c, and
2235 lib/silcclient/idlist.[ch].
2237 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2248 twice for same socket context. Affected file is
2251 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Send error message to application if opening file for
2254 writing during file transfer fails. Affected file is
2255 lib/silcclient/client_ftp.c.
2257 Remove all file transfer sessions for a client that we're
2258 removing from ID cache.
2260 Affected file is lib/silcclient/client_ftp.c.
2262 * Fixed silc_net_addr2bin to return correct address. Affected
2263 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2265 * Fixed file transfer session removing on signoff notify.
2266 Affected file irssi/src/silc/core/silc-servers.c.
2268 * Added the SilcClientFileError to be returned in the monitor
2269 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2270 Affected file lib/silcclient/silcapi.h.

2290 client library. Affected file lib/silcclient/client_prvmsg.c.
2292 * Do not actually remove the client directly from ID cache
2293 during SERVER_SIGNOFF, but invalidate it. This way we
2294 preserve the WHOWAS info for the client. Affected file
2295 silcd/server_util.c.
2297 * Fixed SERVER_SIGNOFF notify handling in the server. The
2298 server is now able to process incoming SERVER_SIGNOFF notify
2299 for a server that it doesn't even know about. It will remove
2300 the clients provided in the notify. Affected file
2301 silcd/packet_receive.c.
2303 * Check for partial packet in data queue after every packet that
2304 was found from the queue. Return and wait for more data if
2305 there is partial data in queue. Affected file is
2306 lib/silccore/silcpacket.c.
2308 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Added SilcClietFileError enum to indicate error in
2311 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2312 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2313 Affected files lib/silcclient/silcapi.h and

2316 * Check that newsize in silc_buffer_realloc is larger than
2317 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2319 * Added better monitor of file transfers. It now monitors
2320 key agreement protocol during the file transfer too. Added
2321 error reporting too. Affected files
2322 irssi/src/silc/core/silc-servers.c,
2323 irssi/src/fe-common/silc/module-formats.[ch].
2325 * Wrote a help file for FILE command.
2327 * Added silc_rng_global_get_byte_fast to get not-so-secure
2328 random data as fast as possible. Random data is read from
2329 /dev/urandom if available and from the SILC RNG if not
2330 available. It is used in padding generation. Affected file
2331 lib/silccrypt/silcrng.[ch].
2333 * All packets in client library are now processed synchronously.
2334 Optimized packet processing a lot. Affected file
2335 lib/silcclient/client.c.
2337 * All server connection packets are processing synchronously
2338 now in server, to optimize packet processing. Affected file
2341 * Include files are installed now only in Toolkit distribution
2342 if make install is given. Affected files: all Makefile.am's.
2344 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2346 * Assure that silc_client_notify_by_server_resolve does not
2347 resolve the client information multiple times. If it cannot
2348 be found by the first it cannot be found at all. Affected
2349 file lib/silcclient/client_notify.c.
2351 * Fixed WHOWAS command reply calling. Affected file
2352 lib/silcclient/command_reply.c.
2354 * Removed all references to silc_idlist_get_client from the
2355 Irssi SILC client since that call is internal call used by
2356 the library. The Irssi SILC client will use now client
2357 retrieval functions found in silcapi.h.
2359 * Fixed a bug in resolving nickname info before sending
2360 private message. It used freed memory. Affected file
2361 irssi/src/silc/core/silc-servers.c.
2363 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Assure my_channels statistics cannot go negative in server.
2366 Affected files silcd/server.c, silcd/server_util.c.

2382 * Added silc_net_localip to return local host's IP address.
2383 Affected file lib/silcutil/silcnet.[ch].
2385 * If key exchange or rekey protocol is active for a connection
2386 parse all packets syncronously since there might be packets
2387 in packet queue that we are not able to process without first
2388 processing packets before them. Affected file silcd/server,
2389 lib/silcclient/client.c.
2391 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2392 whether library should continue processing the packet.
2393 Affected file lib/silccore/silcpacket.h.
2395 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2396 SilcSFTPMonitorData to SFTP server to monitor various

2439 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2440 is incomplete and is being resolved, it won't be resolved
2443 Make sure also that USERS command reply does not resolve
2444 twice information. Affected file is
2445 lib/silcclient/command_reply.c.
2447 Make sure that silc_client_get_clients_by_list does not
2448 resolve twice same information.
2450 * Check for valid client->id in the silc_server_free_client_data.
2451 Affected file silcd/server.c.
2453 * Fixed /GETKEY nick@server not to crash if the server entry
2454 is not found. Affected file lib/silcclient/command.c.
2456 * Fixed the silc_server_check_cmode_rights to check the
2457 requested modes correctly. Affected file silcd/command.c.

2464 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Call the silc_server_udpate_servers_by_server in the
2467 primary router that comes back online in the backup resuming
2468 protocol. Otherwise it routes packets wrong. Affected file
2469 silcd/server_util.[ch], silcd/server_backup.c.
2471 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2474 lib/silcutil/silcbuffmt.[ch].
2476 * Redefined the SILC packet header to include the padding
2477 length. Affected file lib/silccore/silcpacket.[ch].
2479 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2480 length for maximum padding up to 128 bytes). Affected
2481 file lib/silccore/silcpacket.h.
2483 * Removed all backwards support for old 0.5.x MAC thingies.
2484 The SILC packet header change makes it impossible to be
2485 backwards compatible.
2487 * Send the ENDING packet with timeout in the backup resuming
2488 protocol. This is to assure that all routers has connected
2489 to the primary router. Affected file silcd/server_backup.c.
2491 * Changed the RNG to take the first IV from random data. It
2492 used to take it from zero actually. Changed the RNG also
2493 to use /dev/urandom during session. /dev/random is used
2494 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2496 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * Changed the SILC packet header to have the first two bytes
2499 (the packet length) encrypted. Affected files aroung the
2500 code tree, lib/silccore/silcpacket.[ch]. Removed the
2501 SilcPacketCheckDecrypt callback. It is not needed anymore
2502 since the silc_packet_receive_process will determine now
2503 whether the packet is normal or special.
2505 * Implemented the unidirectional MAC keys. Affected files
2506 lib/silcske/silcske.c, silcd/protocol.c and
2507 lib/silcclient/protocol.c.

2514 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Allow backup router to announce servers. All servers
2517 announced by backup router are added to the global list
2518 automatically. Update hte server's socket to our primary
2519 router also when backup router announces a server.
2520 Affected file silcd/packet_receive.c.
2522 * Do not update the client->router in the function
2523 silc_server_udpate_clients_by_server if the client is on
2524 global list. We might fail to find any specific server
2525 for locally connected clients and local cell clients. They
2526 should still use the `from' and not `to' as client->router.
2527 This fixes backup router resuming protocol. Affected file
2528 silcd/server_util.c.
2530 * Decrease channel statistics count only if the channel
2531 deletion worked. Affected files are silcd/server.c and
2532 silcd/server_util.c.
2534 * Added silc_server_update_servers_by_server to update origin
2535 of all server entries. Used during backup router protocol.
2536 Affected files silcd/server_util.[ch], silcd/server.c. and
2537 silcd/backup_router.c.
2539 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new

2541 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2542 lib/silccrypt/silchmac.c.
2544 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Assure that router cannot reroute the same channel message
2547 to the sender. Affected file silcd/packet_receive.c.
2549 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Made better checks that the channel message is not sent
2552 to the router it came from. Affected file is
2553 silcd/packet_send.c. Fixed memory leak too.
2555 * Announce informations for incoming router connection, but
2556 only after checking if it is replaced by backup router.
2557 Affected file silcd/packet_receive.c.
2559 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Fixed the backup resuming protocol to work in multiple
2562 router environment. Affected file silcd/server_backup.c.
2564 * Route packet only to one router in the function
2565 silc_server_packet_send_to_channel. Affected file is
2566 silcd/packet_send.c.
2568 * Fixed silc_server_send_notify_dest to set the broadcast
2569 flag. Fixed the silc_server_send_notify_topic to actually
2570 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2571 Affected file silcd/packet_send.c.
2573 * Changed the SFTP Filesystem interface. Changed the
2574 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2575 the filesystem operation function. The SilcSFTPFilesystem
2576 is now a context that is allocated by all filesystem allocation
2577 functions and it already includes the operations structure
2578 and filesystem specific context. It is given as argument
2579 now to the silc_sftp_server_start. This made the interface
2580 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2581 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2583 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Changed the backup router adding and getting interfaces
2586 in the server. The router that will be replaced by the
2587 specified backup router is now sent as argument. Affected
2588 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2591 * Added silc_net_addr2bin_ne to return the binary form of
2592 the IP address in network byte order. Affected files
2593 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2595 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Check for existing server ID in silc_server_new_server
2598 and in silc_server_connect_to_router_final and remove the
2599 old entry if it exists. Affected file silcd/packet_receive.c,
2602 * Send the channel message always to only one router, either
2603 in upstream or downstream. Affected file is
2604 silcd/packet_send.c.
2606 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Wrote the definition of the backup resuming protocol to the
2609 protocol specification.
2611 * Removed one redundant channel key generation from normal
2612 server during joining procedure. Removed one redundant
2613 channel key sending from server to router during joining
2614 procedure. Affected file silcd/command.c.
2616 * Made minor bugfixes to the backup router resuming protocol.
2617 Affected file silcd/server_backup.c, server.c.
2619 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2622 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2625 * Implemented the backup resuming protocol that is used to
2626 resume the primary router position in the cell after the
2627 primary router comes back online. Affected files
2628 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2629 and silcd/server_util.[ch].
2631 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Sleep two (2) seconds after sending QUIT command to server.
2634 Affected file lib/silcclient/command.c.
2636 * Assure that if outgoing data buffer is pending do not force
2637 send any data. Affected file silcd/packet_send.c.
2639 * Assure that if outgoing data buffer is pending do not force
2640 send any data. Affected file lib/silcclient/client.c.
2642 * Implemented the backup router support when the primary router
2643 goes down. The servers and routers can now use the backup
2644 router as new primary router without loosing connectivity.
2646 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2649 in the server to indicate disabled entry. All data read
2650 from the connection will be ignored and no data is sent
2651 for entry that is disabled. Affected files are
2652 silcd/idlist.h, silcd/server.c.
2654 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Created SFTP client and server test programs in the
2657 lib/silcsftp/tests directory.
2659 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Implemented memory filesystem (virtual filesystem) for
2662 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2665 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Implemented the SFTP (SSH File Transfer Protocol) to the
2668 lib/silcsftp. It includes SFTP client and SFTP server
2671 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Moved lib/silccore/silcprotocol.[ch] to the
2674 lib/silcutil library.
2676 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2677 take variable argument list pointer as argument. Affected
2678 file lib/silcutil/silcbuffmt.[ch].
2680 * Added silc_buffer_set function that is used to set data
2681 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2682 Affected file lib/silcutil/silcbuffer.h.
2684 * Changed various routines in the core library to use the new
2685 silc_buffer_set instead of allocating new buffer only for
2688 * Added 64-bit value formatting and unformatting support to the
2689 silc_buffer_[un]format routines. Affected file is
2690 lib/silcutil/silcbuffmt.[ch].
2692 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2693 to includes/bitmove.h.
2695 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Fixed channel user mode saving in client library. Affected
2698 file lib/silcclient/command[_reply].c.
2700 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Defined the file transfer to the SILC Protocol. Added
2703 new packet type SILC_PACKET_FTP and defined File Transfer
2704 Payload. The mandatory file transfer protocol is SFTP
2705 (SSH File Transfer Protocol). Affected file in addition
2706 of the internet draft is lib/silccore/silcpacket.h.
2708 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2709 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2710 is used as part of backup router protocol when the primary
2711 router of the cell is back online and wishes to resume
2712 the position as primary router.
2714 * Redefined the MAC generation keys in the protocol. The
2715 same key is not used anymore in both direction. Both
2716 direction will now use different keys for sending and
2717 receiving. This fixes a potential security flaw. This
2718 change causes incompatibilities in the protocol.
2720 * Redefined also the MAC computation from the packet.
2721 An packet sequence number is now added to the MAC
2722 computation. This prevents possible replay attacks against
2723 the protocol. This change too causes incompatibilities
2726 Added `sequence' field to the SilcPacketContext to hold
2727 the current sequence number for the packet.
2729 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Added `created' field to the SilcIDListData in the file
2732 silcd/idlist.h to indicate the time when the entry was
2735 * Added `created' field to the SilcChannelEntry too. Affected
2736 file silcd/idlist.h.
2738 * Added `creation_time' aguments to all the announcement functions
2739 in the server. If it is provided then only the entries that
2740 was created after the provided time frame are actually
2741 announced. Affected file silcd/server.[ch].
2743 * The protocol says that the Channel ID's IP address must be
2744 based on the router's IP address. Added check for this in
2745 the silc_server_new_channel when processing incoming New Channel
2746 Payload. Affected file silcd/packet_receive.c.
2748 * Print out the correct version with --version in SILC client.
2749 Affected file irssi/src/silc/core/silc-core.c.
2751 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Fixed WHOWAS command to check for completnes of the client
2754 entry always, not just when the command is coming from client.
2755 Affected file silcd/command.c.
2757 * Added new function silc_server_packet_queue_purge to purge the
2758 outgoing data queue to the network. After the function returns
2759 it is guaranteed that the outgoing packet queue is empty.
2760 Affected file silcd/packet_send.[ch].
2762 * Purge the outgoing packet queue in the rekey protocol's final
2763 callback to assure that all rekey packets go to the network
2764 before quitting the protocol. Affected file silcd/server.c.
2766 * Added silc_client_packet_queue_parse as similar function as
2767 in server to the client library. The affected file is
2768 lib/silcclient/client.c.
2770 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Splitted silcd/server.c and created silcd/server_util.[ch]
2773 for utility functions.
2775 * Added new socket flag SILC_SF_DISABLED to indicate that the
2776 connection is open but nothing can be sent to or received from
2777 the connection. Affected file lib/silcutil/silsockconn.[ch].
2778 The checking for disabled socket is checked in the low level
2779 silc_socket_write and silc_socket_read functions.
2781 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Allow only nicknames and channel names that fits into the
2784 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2786 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * When processing JOIN command reply in server check that if
2789 the channel exists in our global list we'll move it the local
2790 list. Affected file silcd/command_reply.c.
2792 * Fixed the check whether client is joined on the channel already
2793 in JOIN command. Affected file lib/silcclient/command.c.
2795 * Fixed the JOIN command reply to check whether the channel
2796 already exists. Affected file lib/silcclient/command_reply.c.
2798 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Added silc_ske_status_string to map the SKE error numbers
2801 to readable strings. The affected files are
2802 lib/silcske/silcske[_status].[ch].
2804 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2806 * Do not show the private channels on the WHOIS channel list
2807 as it is not allowed by the protocol. The affected file is
2810 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Assure that the packet length digged from the actual packet
2813 is something sensible in the silc_packet_decrypt_rest_special
2814 in lib/silccrypt/silcpacket.c.
2816 * Free and NULL the allocated pointer in silc_hmac_alloc if
2817 the HMAC allocation fails. The affected file is
2818 lib/silccrypt/silchmac.c.
2820 * Print the selected security properties to the log files in
2821 the server. Affected file silcd/protocol.c.
2823 * Add SKE's reference counter even if calling the completion
2824 callback manually. Otherwise it goes negative, although it
2825 does not cause any problems. The affected file is
2826 lib/silcske/silcske.c.
2828 * Remove the client entry with short timeout after giving the
2829 KILL command. Affected file lib/silcclient/command.c.
2831 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2832 case all found clients are already disconnected (WHOWAS would
2833 found them) in the server. Affected file silcd/command.c.
2835 * Update the last_receive (time of last data received) to be
2836 updated only when received private or channel message so that
2837 the idle time showed in WHOIS makes more sense.
2839 * Added boolean field `valid' in to the SilcClientEntry in the
2840 client library to indicate whether the entry is valid or not.
2841 This fixes the nickname change bug on channel when changing
2842 the nickname to be same than the old (like nick to Nick) the
2843 nickname formatter doesn't set the new nick anymore to Nick@host.
2844 Affected file lib/silcclient/idlist.[ch].
2846 * Now actually fixed the nickname changing on disconnection.
2847 Added new function silc_change_nick to the Irssi SILC Client.
2848 Affected file irssi/src/silc/core/client_ops.c,
2849 irssi/src/silc/core/silc-nicklist.[ch].
2851 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Check that the public key exists in the GETKEY command before
2854 trying to encode it. Affected file silcd/command.c.
2856 * Print some notifications on received public keys with GETKEY
2857 command in the Irssi SILC Client. Affected files are
2858 irssi/src/fe-common/silc/module-formats.[ch],
2859 irssi/src/silc/core/client_ops.c.
2861 * Use IDENTIFY command to resolve the server information in the
2862 GETKEY command instead of INFO command. Affected file
2863 lib/silcclient/command.c.
2865 * All command reply functions in the client library now calls
2866 the pending command reply callbacks even if an error has
2867 occurred. The server has done this a long time and now it was
2868 time to move the client library to this as well. Now all
2869 errors can be delivered back to the pending command reply
2870 callbacks if necessary. Affected files are
2871 lib/silcclient/command[_reply].[ch].
2873 * Change the nickname on disconnection back to the username
2874 because in reconnect the server will enforce it to it anyway.
2875 Affected file irssi/src/silc/core/silc-servers.c.
2877 * Fixed a config file parsing bug in the Irssi SILC client.
2878 Affected file irssi/src/silc/core/clientconfig.c.
2880 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * When printing the channel mode on JOIN, verify that the
2883 channel key and channel's HMAC are valid. Affected file
2884 irssi/src/silc/core/client_ops.c.
2886 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2888 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2889 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2890 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2892 * Removed channel key rekey task deleting from the function
2893 silc_server_save_channel_key. Affected file silcd/server.c.
2894 Added explicit timeout task context instead that is used to
2895 delete the task if we are registering a new task before the
2896 new task has elapsed.
2898 * When channel key rekey occurs the client library now saves
2899 the old channel key for a short period of time (10 seconds) and
2900 is able to use it in case some is still sending channel
2901 messages encrypted with the old key after the rekey. Affected
2902 file lib/silcclient/[idlist.h|client_channel.c].
2904 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2906 * Added check to the silc_server_new_id_real to not accept
2907 new ID if it is the sender's own ID. Affected file is
2908 silcd/packet_receive.c.
2910 * Assure that we do not announce ourself or the one we've
2911 sending our announcements when we're router and are announcing
2912 servers to our primary router. Affected file silcd/server.c.
2914 * Fixed silc_server_command_identify_check_client to assemble
2915 correct WHOIS packet. It send corrupted WHOIS packet and
2916 caused problem with router to router connections. Affected
2917 file silcd/command.c.
2919 Fixed also silc_server_command_whois_check the same way
2920 as for the IDENTIFY command.
2922 * Added new SilcIDListStatus to the server in the SilcIDListData
2923 structure. The status now includes the current status of
2924 the entry (like registered, resolved etc.). Affected file
2925 silcd/idlist.[ch]. Defined a bunch of different status types
2926 as well. This replaced the old boolean registered field as well.
2928 Added resolve_cmd_ident field to the SilcClientEntry structure
2929 too so that if the entry is for example being resolved so
2930 another command may attach to the same pending command reply
2931 without requiring to resolve the same entry again. This concept
2932 should optimize the WHOIS and the IDENTIFY resolving under
2933 heavy load by taking away unnecessary resolving for entries
2934 that are being resolved already.
2936 Added support for adding multiple pending commands for one
2937 command idenfier. Affected file silcd/command[_reply].[ch].
2939 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2940 before deleting the data. Otherwise the hash table will have
2941 freed data in comparison functions. Affected file is
2942 silcd/command_reply.c.
2944 * Fixed silc_idlist_replace_client_id to add the new entry to
2945 the cache with NULL nickname. Otherwise there will be invalid
2946 memory as the nickname after the nickname is freed. Affected
2947 file silcd/packet_receive.c.
2949 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2950 saved into wrong slots because the previous number of entries
2951 was not taken into account. Affected file silcd/idlist.c.
2952 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2954 * If we are router and we receive JOIN notify to a channel that
2955 does not have any users then notified client is marked as the
2956 channel founder, as it is it. The affected file is
2957 silcd/packet_receive.c
2959 * Added to the extended hash table API's table_del_*ext functions
2960 the destructor as argument too, so that the caller can decide
2961 which destructor to use or whether to use destructor at all.
2962 Affected file lib/silcutil/silchashtable.[ch].
2964 * Fixed ID Cache purging. It actually deleted the entries from
2965 the hash table after the data was freed. The hash table ended
2966 up comparing freed memory. The affected file is
2967 lib/silccore/silcidcache.c.
2969 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Fixed Irssi SILC client's KILL command's HELP syntax.
2973 * The USERS command now resolves the detailed user information
2974 if the userinfo field is missing. Affected file is
2975 lib/silcclient/command_reply.c.
2977 * Do not print error in silc_file_read if the read file does
2978 not exist. Just silently return NULL. Affected file is
2979 lib/silcutil/silcutil.c.
2981 * Fixed the silc_log_output to not wine about NULL filename
2982 and to not create some bogus " " filename. Affected file is
2983 lib/silcutil/silclog.c.
2985 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Fixed various printing bugs on the user interface in the
2988 Irssi SILC Client. Minor changes that were forgotten from
2991 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Fixed the configure.in.pre and the compilation and distribution
2994 environment to support the new autoconf 2.52. That version is
2995 now required to compile the CVS trunk.
2997 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3000 to generally parse user@fqdn format strings. Affected file
3001 lib/silcutil/silcutil.c.
3003 * Added nickname_format and nickname_force_format fields to the
3004 SilcClientParams structure. The first one defines the format
3005 for the nicknames that the library will enforce if the receives
3006 multiple same nicknames. The second one is boolean value and
3007 can be used to force the library to always enforce the format
3008 to the nicknames regardles whether there are multiple nicknames
3009 or not. This configurable formatting was employed to flexibly
3010 support accessing multiple nicknames from the user interface.
3011 The userinterface can now set the nicknames to what ever format
3012 they prefer. Affected file lib/silcclient/silcapi.h.
3014 Added function silc_client_nickname_format to the file
3015 lib/silcclient/idlist.c. It performs the nickname formatting.
3017 Added new field `hostname´ to the SilcClientEntry context.
3018 It holds the hostname of the client. Affected file is
3019 lib/silcclient/idlist.h.
3021 * Irssi SILC Client sets the nicknames in nick@hostn format.
3022 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3023 irssi/src/silc/core/silc-core.c.
3025 The WHOIS printing now also shows both the real nickname and
3026 the formatted nickname so that user knows how to access the
3027 user if there are multiple same nicknames cached. Affected
3028 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3029 printing formatting too to take the hostname now as a separate
3030 argument. The Affected file is
3031 irssi/src/fe-common/silc/modules-formats.[ch].
3033 * Changed the silc_client_get_clients_local to accept the formatted
3034 nickname as argument. It accepts the real nickname too but the
3035 formatted nickname can be used to find the true entry from
3036 multiple entries. Affected file lib/silcclient/silcapi.h and
3037 lib/silcclient/idlist.c.
3039 * Added nickname_format_parse field to the SilcClientParams.
3040 It is a callback function provided by the application to parse
3041 the nickname out of the formatted nickname string. The library
3042 calls it to get the nickname from the formatted string. Since
3043 the application generally knows better the format of the nickname
3044 string it parses it instead of the library, even though library
3045 encodes the formatted string. If the callback function is not
3046 provided then the library will use the string as is. The
3047 affected file is lib/silcclient/silcapi.h.
3049 * All the nickname strings passed to the client library in
3050 commands are now expected to be formatted nickname strings.
3051 If the command does not support the formatted nickname string
3052 it will assume that the sent string is the actual nickname.
3053 Affected file lib/silcclient/command.c.
3055 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Added public key authentication support to OPER and SILCOPER
3058 commands in the client library. Affected file is
3059 lib/silcclient/command.c.
3061 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Changed the get_auth_methdod client operation to be asynchronous.
3064 It can be async if the application resolves the authentication
3065 method from the server during the negotiation. Added new
3066 SilcGetAuthMeth completion callback that the application will
3067 call after resolving the authentication method.
3069 Added function silc_client_request_authentication_method that
3070 the application can use to resolve the authentication method
3071 from the server. Added also SilcConnectionAuthRequest callback
3072 that the library will call after the server has replied. The
3073 application can call this function if it does not know the
3074 current authentication method.
3076 Affected files are lib/silcclient/client.c and
3077 lib/silcclient/silcapi.h.
3079 * The Irssi SILC client now automatically resolves the authentication
3080 method incase any configuration information is not present (and
3081 currently there never is). The affected file is
3082 irssi/src/silc/core/client_ops.c.
3084 * Fixed public key authentication from the client library.
3085 Affected file lib/silcclient/protocol.c. Changed also the
3086 protocol specification about the public key authentication in
3087 the connection authentication protocol. The actual data to be
3088 signed is now computed with a hash function before signing.
3090 * Fixed the public key authentication from the server as well.
3091 Affected file silcd/protocol.c.
3093 * Removed the mlock()'s from the memory allocation routines.
3094 Affected file lib/silcutil/silcmemory.c. The ./configure does
3095 not check anymore for the mlock(). Affected file is
3098 * Fixed USERS command in server to allow the execution of the
3099 command for private and secret channels if the client sending
3100 the command is on the channel. Affected file silcd/command.c.
3102 * Fixed silc_client_get_clients_local to return the clients
3103 count correctly. It could return wrong value. Affected file
3104 lib/silcclient/idlist.c.
3106 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3108 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3109 types. The assembler optimizations seemed not to like 64-bit
3110 data types. The assmebler optimizations thus are now enabled
3111 also for BSD systems as opposed to only enable them for Linux.
3113 * Do not check for threads at all on BSD systems. Affected
3114 file configure.in.pre.
3116 * Removed -n and -h options from the Irssi SILC Client since
3117 they are not used in silc.
3119 * Fixed the prime generation to assure that the first digit
3120 of the generated random number is not zero since our conversion
3121 routines does not like number strings that starts with zero
3122 digit. If zero digit is seen the random number is regenerated.
3123 This caused some corrupted RSA keys when the zero first digit
3124 was met. Affected file lib/silcmath/silcprimegen.c.
3126 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3128 * Fixed WIN32 configuration in the ./configure script.
3129 Fixed to include xti.h on environments that has it.
3130 Patches by Carsten Ilchmann and andrew.
3132 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Changed the silc_id_create_client_id to be collision
3135 resistant. It is now assured that there cannot be created
3136 two same client ID's. I suspect that some weird bugs in
3137 the server were actually caused by duplicate Client IDs.
3138 Affected file silcd/serverid.[ch]. A router receiving
3139 new ID now also assures and informs the sending server
3140 if the ID caused collision.
3142 * Changed the silc_id_create_channel_id to also assure that
3143 there are no collisions.
3145 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Statement about ignoring the Mutual Authentication flag when
3148 performing rekey with PFS was a bit misleading. It is ignored
3149 if it was set in the initial negotiation, it cannot be even
3150 set in the rekey. Fixed in the ke-auth draft. Started the
3151 new versions of the protocol drafts in the doc/.
3153 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Fixed a bug in silc_client_command_identify_save when saving
3156 new channel information. The channel name was no duplicated
3157 and caused crash on exit. Affected file is
3158 lib/silcclient/command_reply.c.
3160 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3162 * Fixed the getkey command handling in the server. Send just
3163 empty OK reply to the sender if the key could not be fetched
3164 (but everything else was ok, like the key just was not available).
3165 Changed the public key parameter to optional in the protocol
3166 specs so that empty OK reply can be sent. Affected file
3169 Added a message to Irssi SILC client to tell to user if the
3170 server did not return a public key.
3172 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Fixed a channel key regeneration bug. It registered new
3175 timeout tasks exponentially until all system resources were
3176 used. Affected file silcd/server.c.
3178 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3180 * Added the SILC Document generator to the scripts/silcdoc.
3181 It can be used to generate the Toolkit Reference Manual out
3182 of the source tree. Internally it will also use the RoboDoc
3183 generator now imported in util/robodoc.
3185 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3187 * Added couple of return's in rekey protocol if error orccurred
3188 during the protocol. The execution must be terminated.
3189 Affected file silcd/protocol.c. Also, terminate the protocol
3190 always with timeout.
3192 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * The client's Client ID was created initally from the wrong
3195 nickname (it could have been in format nick@host) in the
3196 silc_server_new_client. Affected file silcd/packet_receive.c
3198 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Added some SILC_LOG_ERROR's to various error conditions
3201 if client could not be added to ID cache. Affected files
3202 silcd/packet_receive.c and silcd/server.c.
3204 * When client's sock->user_data is freed, NULL also the
3205 client->router and client->connection pointers. Added check
3206 for these pointers being NULL to various places around the
3207 code. Affected file silcd/server.c.
3209 * Added client->data.registered == TRUE checks to various
3210 places around the code to assure that unregistered client's
3211 are not handled when it is not allowed. Affected file
3214 * Added `bool registered' fields to all
3215 silc_idlist_[server|client]_get_* routines to indicate whether
3216 the fetched client needs to be registered or not. Affected
3217 file silcd/idlist.[ch].
3219 * Add your own entry as registered to the ID cache in the
3220 server. Affected file server.c.
3222 * Fixed a bug in silc_server_new_server. The SilcServer was
3223 set as the new server's context instead of SilcServerEntry.
3224 This naturally caused some weird bugs.
3226 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3228 * Do not delete the channel rekey task when adding it
3229 for in silc_server_create_channel_key.
3231 * Changed the silc_server_create_channel_key to return
3232 TRUE or FALSE to indicate the success of the channel key
3235 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3237 * Fixed MSVC++ project files and added missing files to

3240 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * Do not add TCP_NODELAY flag if the operating system
3243 does not have it defined. Affected files are
3244 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3246 * Fixed buffer overflow from Irssi SILC Client. Affected
3247 file irssi/src/fe-common/core/themes.c.
3249 * Fixed double free in client library in the file
3250 lib/silcclient/client.c when disconnecting from server.
3252 * Applied double free patch from cras to Irssi SILC client.
3253 Affected files irssi/src/core/[modules/expandos].c
3255 * Fixed the disconnection handling to Irssi SILC Client.
3256 The application must call silc_client_close_connection
3257 in ops->connect client operation in case of failure of
3258 the connection. Affected file is
3259 irssi/src/silc/core/client_ops.c.
3261 * Do not set sock->protocol to NULL in the function
3262 silc_client_close_connection after executing the protocol's
3263 final callback since the sock might not be valid anymore.
3264 Affected file lib/silcclient/client.c.
3266 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3268 * Do not enable SILC_THREADS if the linking with libpthread
3269 did not happen. Affected file configure.in.pre.
3271 * Added notion to protocol specification that server must
3272 verify the sent authentication payload with CMODE when
3273 setting the channel founder key. Implemented it to the
3274 server. Affected file silcd/command.c.
3276 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Added _EXTRA_DIST SILC distribution variable to the
3279 distributions file. It is used to conditionally add extra
3280 files or directories to the specific distribution. Affected
3281 files ./prepare, Makefile.am.pre and distributions.
3283 Removed the `_' from the start of the distribution names.
3286 * Added README.WIN32 for instructions to compile the Toolkit
3289 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Fixed a double free in disconnection in the server. Affected
3292 file is silcd/server.c.
3294 * Fixed the lib/silcske/groups.c to work now also with GMP
3295 MP library. The string conversion did not work when using
3296 specific base and the base is indicated in the string as well.
3298 * Created win32/ directory which now includes MSVC++ specific
3299 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3300 It will appear only in the toolkit distribution
3302 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3304 * Changed the key material distribution function in case when
3305 the hash output is too short. The data is now concatenated
3306 a bit differently than it used to. Made the change to the
3307 SKE protocol specification.
3309 * Added better GMP detection to configure.in.pre. A patch
3312 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * Fixed a minor bug in SKE that might cause some problem on
3315 some platforms. Affected file lib/silcske/silcske.c.
3317 * Added the cookie checking for initiator in the SKE. It checks
3318 that the responder returns the sent cookie unmodified. The
3319 affected file is lib/silcske/silcske.c. Added new SKE
3320 error type INVALID_COOKIE that can be sent during the
3321 negotiation. Fixed some memory leaks as well.
3323 * Added the "invalid cookie" error message to Irssi SILC client's
3326 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3328 * Added `task_max' field to the SilcClientParams to indicate
3329 the maximum tasks the scheduler can handle. If set to zero,
3330 default values are used. Affected file lib/silcclient/silcapi.h.
3332 * Fixed memory leaks in silc_client_close_connection. Affected
3333 file lib/silcclient/client.c.
3335 * Added silc_client_del_client_entry to client library to free
3336 all memory of given client entry. Affected file is
3337 lib/silcclient/idlist.[ch].
3339 * Added new functions silc_client_del_channel and
3340 silc_client_del_server to delete channel and server entries.
3341 Affected file lib/silcclient/[silcapi.h/idlist.c].
3343 * Removed silc_client_del_client_by_id from silcapi.h.
3345 * Fixed the INFO command to return the server's own info
3346 correctly when querying by Server ID. Affected file is
3349 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Removed the non-blocking settings in WIN32 code in the
3352 silc_sock_[read/write] and added SleepEx instead. Affected
3353 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3354 of input data is now checked with FIONREAD and ioctlsocket.
3356 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3358 * Call silc_schedule_task_del_by_context in the
3359 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3360 Affected file lib/silccore/silcprotocol.c.
3362 * Call silc_protocol_cancel for active protocols in the
3363 silc_server_close_connection if the funtion
3364 silc_server_free_sock_user_data has not been called.
3365 Affected file silcd/server.c.
3367 * Generic tasks cannot be deleted using the del_by_fd
3368 task deleting function since generic tasks does not match
3369 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3371 * Added a notion to SILCOPER help file that the SILCOPER works
3372 only on router server, not on normal server.
3374 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3376 * Added for WIN32 support for the new scheduler as well.
3377 Affected file lib/silcutil/win32/silcwin32schedule.c.
3379 * Fixed the SHA1 implementation to work on various platforms.
3381 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3384 API. It is part of the scheduler now. Everything else is
3385 as previously but some functions has changed their names.
3386 Checkout the lib/silcutil/silcschedule.h for the interface.
3387 Updated all applications to use the new interface. Affected
3388 files are lib/silcutil/silcschedule.[ch].
3390 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3392 * Found a bug in the SKE implementation. The HASH value,
3393 specified by the protocol, was not computed correctly. The
3394 public key of the responder was not added to the computation
3395 even though it is mandatory. Affected file lib/silcske/silcske.c.
3396 This unfortunately causes incompatibilities with older
3397 clients and servers.
3399 * Added WIN32 specific network init and uninit functions:
3400 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3401 the Winsock2. Affected file lib/silcutil/silcnet.h and
3402 lib/silcutil/win32/silcwin32net.c.
3404 * Set the socket always to nonblocking mode on WIN32 after
3405 reading data or writing data. Affected file is
3406 lib/silcutil/win32/silcwin32sockconn.c.
3408 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3410 * Fixed various compilation problems under WIN32. Affected
3411 files lib/silcutil/win32/silcwin32thread.c and
3412 lib/silcutil/win32/silcwin32schedule.c.
3414 * Removed all _internal.h #includes from public header
3415 files. Internal headers must never be included from
3418 Removed also the lib/silcske/payload_internal.h file.
3420 * All include files that may be needed (public and some others
3421 included by the public headers) by application developers are
3422 now copied to the ./includes directory. It does not copy any
3423 internal headers. Affected file Makefile.defines.pre and all
3424 Makefile.am's under lib/ and subdirs.
3426 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * Do not change the ~/.silc directory's permissions automatically.
3429 Affected file irssi/src/silc/core/clientutil.c.
3431 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3433 * Do not cancel the protocol in silc_server_close_connection
3434 it might cause recursion. Now cancelled in the function
3435 silc_server_free_sock_user_data. Affected file silcd/server.c.
3437 * Fixed the silc_server_remove_clients_by_server to regenerate
3438 the channel keys correctly finally. Added also new function
3439 silc_server_remove_clients_channels to actually do it.
3440 Affected file silcd/server.c.
3442 * Fixed the silc_server_new_channel to not crash by giving
3443 wrong router to the new channel. Affected file is
3444 silcd/packet_receive.c.
3446 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3449 which is given as argument to the silc_client_alloc now.
3450 It can be used to configure the client and set various parameters
3451 that affect the function of the client.
3453 * The USERS command in server did not check whether the channel
3454 is private or secret. Affected file silcd/command.c.
3456 * Added new argument to the USERS command in protocol specification.
3457 The USERS command now can take the channel name as argument
3458 as well. Added support for this in client and server and
3459 updated the protocol specs.
3461 * Completed the GETKEY command in client. It can be now used
3462 to fetch also servers public key not only some clients.
3463 Affected files lib/silcclient/command[_reply].c.
3465 * Added silc_client_get_server to return server entry by the
3466 server name. Affected files lib/silcclient/silcapi.h and
3469 * Redefined the IDENTIFY command in protocol specification to be
3470 more generic. It now can be used to query information about
3471 any entity in the SILC Network, including clients, servers and
3472 channels. The query may be based either the entity's name
3473 or the ID. Added support for this in both client and server.
3475 Affected files silcd/command.c and lib/silcclient/command.c
3476 and command_reply.c.
3478 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3479 the _from_client and _from_server functions. Affected file
3482 * Added silc_client_get_channel_by_id_resolve to the file
3483 lib/silcclient/silcapi.h to resolve channel information by
3484 its ID. Added also silc_client_get_channel_by_id that
3485 does not resolve it from the server.
3487 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3489 * Added SilcServerEntry context into the client library
3490 to represent one server. The INFO command now allocates
3491 these to save the resolved server info. For now on the
3492 client library will also keep information about servers,
3493 connected and resolved with INFO.
3495 The INFO command now allocates the SilcServerEntry context
3496 and saves the server info there. The COMMAND_REPLY in
3497 the INFO now returns the parameters to application in
3498 same order as defined in the protocol specification.
3500 The entries are cached in the client->server_cache.
3502 * The INFO command is now issued after received the Client ID
3503 from the server. Affected file lib/silcclient/client.c.
3505 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3506 to the application as the mode changer might be server.
3507 It is guaranteed that NULL is not returned anymore to the
3508 application. Affected file lib/silcclient/client_notify.c.
3510 The ID Type is now also passed to the application so that
3511 it can check whether the returned entry is SilcClientEntry
3514 Added new function silc_client_get_server_by_id to return
3515 the server entry by ID. Affected files are the
3516 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3518 * Do not create the channel in the Irssi SILC Client when issuing
3519 the JOIN command but when received the sucessful JOIN command
3520 reply. Otherwise the channel might get created even though we
3521 could not join it. The Affected file is
3522 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3524 * Fixed a channel joining bug in router. The router must also
3525 check the channel modes, invite and ban lists etc. when serving
3526 the JOIN command sent by normal server. Affected file is
3527 silcd/command.c. The router now resolves the client's
3528 information from the server who sent the JOIN command if it
3529 does not know it, and processes the JOIN command only after
3532 * Changed the SilcCommandCb to take new argument; void *context2.
3533 Affected file lib/silccore/silccommand.h
3535 The second argument in the command callbacks in the server now
3536 includes the SilcServerCommandReplyContext if the command was
3537 called as pending command callback from the command reply.
3538 Otherwise it is NULL. When called as pending the status of the
3539 command reply will be checked and if it was erronous the
3540 error will be sent to the original sender of the command.
3541 This way the client always receives the error messages even
3542 though the server was actually the one who received the error
3543 when it resent the command to router, for example. Affected
3544 files silcd/command[_reply].[ch].
3546 * Fixed sending WHOWAS command's error message to client if
3547 the requested client could not be found. It was missing.
3550 * Changed the CMODE and CUMODE commands reply arguments in the
3551 protocol specification. The Channel ID is now sent in both
3552 of the commands to identify the channel. Implemented this
3553 new feature to the client and server. Affected files
3554 lib/silcclient/command_reply.c and silcd/command.c.
3556 * Made better checks for invite and ban lists in the JOIN
3557 command in server. Affected file silcd/command.c.
3559 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3561 * The server now performs the incoming host IP/DNS lookup
3562 using the silc_socket_host_lookup and thus does not block
3563 the server anymore. Affected file silcd/server.c.
3565 * Completed the multi-thread support for SILC Scheduler in
3566 the lib/silcutil/silcschedule.c.
3568 * Fixed the configure.in.pre to detect the pthread correctly
3571 * Fixed a deadlock in silc_task_queue_wakeup in the file
3572 lib/silcutil/silctask.c.
3574 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Added new function silc_schedule_wakeup that is used in
3577 multi-threaded environment to wakeup the main thread's
3578 schduler. It needs to be used when a thread adds a new task
3579 or removes a task from task queues. After waking up, the
3580 scheduler will detect the task queue changes. If threads
3581 support is not compiled in this function has no effect.
3582 Implemented the wakeup mechanism to both Unix and WIN32
3583 systems. Affected files are lib/silcutil/silcschedule.[ch],
3584 lib/silcutil/unix/silcunixschedule.c and the
3585 lib/silcutil/win32/silcwin32schedule.c.
3587 * Added new function silc_task_queue_wakeup to wakeup the
3588 scheduler by the specified task queue. Affected file
3589 lib/silcutil/silctask.[ch].
3591 * The silc_socket_host_lookup_start now wakes up the scheduler
3592 after adding the timeout task. Affected file is
3593 lib/silcutil/silcsockconn.c.
3595 * The silc_socket_host_lookup is synchronous now if the threads
3596 support is not compiled in. However, the callback is still
3597 called asyncronously through the scheduler, anyway. Affected
3598 file lib/silcutil/silcsockconn.c.
3600 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Added new function silc_socket_host_lookup to perform
3603 asynchronous IP and FQDN lookups for the socket connection.
3604 Affected files lib/silcutil/silcsockconn.[ch].
3606 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3609 that may or may not compile the mutex support in.
3611 Changed the silc_mutex_alloc interface. It allocates the
3612 mutex now to the sent pointer and returns TRUE or FALSE.
3614 Affected file lib/silcutil/silcmutex.h.
3616 * Wrote the SILC Task Queue interface to support multi-threads.
3617 Affected file lib/silcutil/silctask.[ch].
3619 * Wrote the SILC Scheduler to support multi-threads. Affected
3620 file lib/silcutil/silcschedule.c.
3622 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3624 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3625 in lib/silcutil/win32/.
3627 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Defined SILC Mutex API and SILC Thread API and implemented
3630 them for Unix. Affected files are
3631 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3632 lib/silcutil/unix/silcunixmutex.c and
3633 lib/silcutil/unix/silcunixthread.c.
3635 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3637 * Fixed the silc_server_remove_clients_by_server's channel
3638 key re-generation. The hash table handling was incorrect
3639 and would not work with many channels. Affected file is
3642 * Fixed some memory leaks around the server code.
3644 * Rewrote the silc_server_get_users_on_channel to support IPv6
3645 based Client ID's. Affected file silcd/server.c.
3647 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3648 specification. However, a separate document must be written
3649 to define the detailed signing procedure and the payload
3650 associated with the flag. Defined the flag to the
3651 lib/silccore/silcchannel.h as well.
3653 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3655 * Changed the dynamic tables to static size tables in the
3656 lib/silccrypt/silchmac.c.
3658 * Removed GCC dependencies from the code. A patch by cras.
3660 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Do not show the error "Error receiving packet bla bla"
3663 in server if it really was not an error (-2 means that reading
3664 is pending). Affected file silcd/server.c.
3666 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3668 * Fixed a possible crash in silc_server_remove_clients_by_server
3669 in silcd/server.c. Fixed there also some memory leaks.
3671 * Fixed the silc_idlist_replace_client_id. It could replace
3672 wrong key in the hash table. Affected file silcd/idlist.c.
3674 * Do not check whether there are global users on the channel
3675 if the channel->global_users is FALSE. Affected functions
3676 silc_server_remove_from_one_channel and
3677 silc_server_remove_from_channels in silcd/server.c. Also,
3678 do not check if the removed client is local as we can be
3679 sure that global client was not removed from the channel
3680 and checking for global users is not needed.
3682 * The silc_server_remove_clients_by_server now re-generates
3683 the channel keys correctly for those channels that had
3684 clients removed from them. Affected file silcd/server.c.
3686 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Found the reason of random crashes in the server. We weren't
3689 ignoring the SIGPIPE signal (which can be sent in write())
3690 and it crashed the server. Affected file silcd/silcd.c.
3692 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3694 * Assure that sock->user_data is not NULL in the function
3695 silc_server_packet_send in silcd/packet_send.c.
3697 * Disconnect the remote connection if it could not be added
3698 to any ID lists in the server. The affected file is
3701 * Check in silc_server_packet_send[_real/dest] that the
3702 socket is not disconnecting and ignore the data if it is.
3703 Affected file silcd/packet_send.c.
3705 * Define inline to __inline on native WIN32 compilation.
3706 Affected file includes/silcwin32.h.
3708 * Added some explicit type casts for inline code since MSVC
3709 require them. Affected files lib/silcutil/silcbuffer.h,
3710 lib/trq/silcdlist.h and lib/trq/silclist.h.
3712 * Print warning in log files from now on if the packet
3713 decryption fails. Affected file silcd/server.c.
3715 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3717 * Changed the `say' client operation's interface to accept
3718 new `type' argument to indicate the type of the message sent
3719 by the library. The application may filter the library's
3720 messages according the type. The affected file is the
3721 lib/silcclient/silcapi.h.
3723 * Added two new functions to lib/silcclient/silcapi.h:
3724 silc_client_del_client and silc_client_del_client_by_id.
3725 Affected file lib/silcclient/idlist.c.
3727 * Moved the clientincludes.h from includes/ to silc/ and
3728 serverincludes.h from includes/ to silcd/.
3730 * The modes for the CMODE and CUMODE are now passed as
3731 uint32 for application with COMMAND_REPLY. The affected
3732 file is lib/silcclient/command_reply.c.
3734 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3736 * /WHOIS without arguments shows client's own information.
3737 Affected file lib/silcclient/command.c.
3739 * Changed PING to not accept any arguments. The specs
3740 says that client can ping only the connected server so
3741 requiring an argument is not needed. Affected file is
3742 lib/silcclient/command.c.
3744 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Fixed a fatal bug in private message sending and reception
3747 encryption and decryption when using private message keys.
3748 The implementation was incorrect and did not follow the
3749 specification. It causd that some of the message were
3750 lost since it did not use the sending and receiving keys
3751 as the protocol suggests. This has been fixed and will cause
3752 incompatibilities with older clients when sending private
3753 message encrypted with private message keys. Affected files
3754 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3755 and various other in Irssi SILC Client.
3757 Added `responder' boolean argument to the functions
3758 silc_client_add_private_message_key[_ske] to indicate when
3759 the key is added as responder or initiator of the key
3762 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3764 * Removed the silc_ske_check_version function and created
3765 a SilcSKECheckVersion callback. Added also a function
3766 silc_ske_set_callbacks that is now used to set all SKE
3767 callbacks. The callback functions are not given to
3768 the SKE functions anymore, but this function is used to
3771 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3773 * Added `silc_version' argument to the silc_client_alloc
3774 to define the version of the application for the library.
3775 The library will use the version string to compare it
3776 against the remote host's (usually a server) version
3777 string. Affected file lib/silcclient/silcapi.h
3779 * Added the KE protocol context to Key Agreement context
3780 in client library so that we can abort the SKE if it
3781 is in process when we get timeout. Affected file is
3782 lib/silcclient/client_keyagr.c.
3784 * Do not resolve the client ID forever if it returns in the
3785 first time that such client does not exist. This was done
3786 for example with private message. Affected file is
3787 lib/silcclient/client_prvmsg.c.
3789 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3791 * Do not add regex.h for WIN32. The affected file
3792 includes/silcincludes.h.
3794 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3795 not work yet 100%. It generates the DLL's automatically
3796 when compiling with --with-win32 under cygwin.
3798 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * lib/contrib/regex.c is not compiled on WIN32.
3802 * Added silc_net_get_socket_opt function to the
3803 lib/silcutil/silcnet.h.
3805 * Added includes/silcwin32.h for WIN32 specific includes
3808 * Do not use ptime structure or any of the posix process
3809 functions on WIN32 in lib/silccrypt/silrng.c.
3811 * Added silc_gettimeofday to provide generic function
3812 for struct timeval on all platforms. Added the function
3813 to lib/silcutil/silcutil.h.
3815 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3817 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3818 library as they clearly belong there. As a plus side we
3819 can make the actual socket connection routines platform
3822 Added also new generic function silc_socket_read and
3823 silc_socket_write (that used to be silc_packet_[read/write].
3824 The implementation of these are platform specific.
3826 * Added WIN32 specific routines of silc_socket_[read/write]
3827 to lib/silcutil/win32/silcwin32sockconn.c.
3829 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Added preliminary support for native WIN32 compilation under
3832 cygwin (using the -mno-cygwin option for GCC) to the
3833 ./configure.in.pre. The --with-win32 now prepares the
3834 compilation for native WIN32.
3836 * Rewrote the SILC Scheduler interface in the file
3837 lib/silcutil/silcschedule.h. The scheduler is now context
3838 based and does not have anymore any global static scheduler.
3839 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3840 and created lib/silcutil/win32 directory for WIN32 based
3843 * Added Unix specific network routines to the
3844 lib/silcutil/unix/silcunixnet.c and the old
3845 lib/silcutil/silcnet.c includes now only generic routines.
3847 Added WIN32 specific network routines to the
3848 lib/silcutil/win32/silcwin32net.c.
3850 * Added Unix specific utility functions from the
3851 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3853 * Added WIN32 SILC Scheduler to the file
3854 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3857 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3859 * Do not handle JOIN notify in the server if the target client
3860 is not registered (idata->registered == FALSE). The affected
3861 file is silcd/packet_receive.c.
3863 * Update the nickrec->founder in event_cumode in the Irssi SILC
3864 client. Affected file irssi/src/silc/core/silc-channels.c.
3866 * Fixed the CUMODE_CHANGE notify handling in the server when
3867 server and router are announcing their clients on channels.
3868 Now the mode changes are saved and notified correctly. The
3869 affected file is /silcd/packet_receive.c.
3871 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3872 They really did not replace the cache entry in the ID Cache.
3873 Now they do that. Affected file silcd/idlist.c.
3875 * Fixed the KICK notify handling in the Irssi SILC client to
3876 update the channel records so that the kicked client does not
3877 appear to be on the channel. The affected file is
3878 irssi/src/silc/core/silc-channels.c.
3880 * Always update the conn->current_channel when executing command
3881 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3883 * Fixed the KILL notify handling in Irssi SILC client to remove
3884 the killed client on all channels.
3886 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Fixed the silc_parse_command_line to remove extra spaces
3889 from the start and end of the arguments. Affected file is
3890 lib/silcutil/silcutil.c.
3892 * Cancel and free any active protocol in the function
3893 silc_server_close_connection. Affected file silcd/server.c.
3895 * Cancel and free any active protocol in the function
3896 silc_client_close_connction. Affected file is
3897 lib/silcclient/client.c.
3899 * Do not execute the KILL command for clients that are in
3900 history (ie. they are not in the network). Affected file is
3903 * Fixed KILL notify handling, client does not crash anymore.
3904 Affected file irssi/src/silc/core/silc-channels.c.
3906 * Reduced the default packet buffer size from 2048 to 1024 in
3907 lib/silccore/silcpacket.c.
3909 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3910 counter to the SKE context that is incresed when the SKE library
3911 performs async operation outside the library. If the outside
3912 process frees the SKE context and FREED status will be set
3913 and the library will detect after the sync operation that the
3914 libary is freed. The affected files are
3915 lib/silcske/silcske[_status].[ch].
3917 * Resolve the client entry information in the function
3918 silc_client_channel_message to assure that NULL pointer is not
3919 passed as client entry to the application. */
3921 * Fixed the task timeout calculation to assure that there is
3922 never negative timeouts. The affected file is
3923 lib/silcutil/silcschedule.c.
3925 * Fixed the channel user mode notification sending in server.
3926 It was sent point-to-point to the router (or to server by router)
3927 but it needs to be destined to a channel. The routines now
3928 supports sending the channel user mode notifys to the channels
3929 when announcing clients and channels. Affected files are
3930 silcd/server.c and silcd/packet_receive.c.
3932 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3933 It did not actually replace the old channel entry in the cache.
3934 Affected file lib/silcclient/client_notify.c.
3936 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Fixed a possible crash in silc_packet_send_prepare. It now
3939 assures always that there is enough space in the buffer and
3940 at the tail area of the buffer (for MAC).
3942 Fixed the inbound buffer reallocation in silc_packet_read.
3943 It was old code and did not handle the reallocation correctly.
3946 The affected file is lib/silccore/silcpacket.c.
3948 * Fixed buffer overflow in silc_parse_nickname in the file
3949 lib/silcutil/silcutil.c.
3951 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * make install generates new server keys only if there is not
3956 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3959 Added check that if the NOREPLY is set then we will not send
3960 the away message. This avoids infinite loop of away messages
3961 if both clients are away. The affected file is
3962 lib/silcclient/client_prvmsg.c.
3964 * Fixed client crash if /NICK was given without arguments.
3965 Affected file lib/silcclient/command.c.
3967 * Server does not send the invite list in INVITE command back
3968 to the client if the list was not altered. Added this notion
3969 to the protocol spec as well. Affected file silcd/command.c.
3971 Fixed possible crash in INVITE command by checking the
3972 value of silc_server_get_client_route command.
3974 * Fixed the INVITE notify type handling. The arguments are now
3975 taken in correct order and client does not crash. The affected
3976 file is irssi/src/silc/core/silc-channels.c.
3978 Removed the "Inviting xxx to channel" message from the
3979 client library away and let the application handle it.
3980 Affected file lib/silcclient/command.c. Added that message
3981 to Irssi SILC client's message formats.
3983 * Fixed CMODE command crash in client. It now checks the
3984 amount of arguments correctly and does not crash. The affected
3985 file is lib/silcclient/command.c.
3987 * Do not create new channel automatically in silc_channels_join
3988 but check whether the channel by that name already exists.
3989 Affected file irssi/silc/core/silc-channels.c.
3991 * Do not send the SERVER_SIGNOFF to router if the disconnected
3992 entity was the router. Affected file silcd/server.c.
3994 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3995 SILC client as it was missing from there.
3997 Added the handling of the KICK notify to the Irssi SILC client
3998 as it was missing. Added "you have been kicked" message to
3999 Irssi SILC client's message modules formats.
4001 Added the handing of the KILL notify to the Irssi SILC client
4002 as it was missing. Added the kill message module formats
4005 The affected file is irssi/src/silc/core/silc-channels.c.
4007 * The router did not save the channel mode the server announced.
4008 Affected file silcd/packet_receive.c.
4010 * Fixed a possible crash in INFO command in server. If the
4011 server did not provide the server info it crashed. Affected
4012 file silcd/command.c.
4014 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Fixed the GETKEY command in the server to check also the
4017 global list. Otherwise the GETKEY would not work correctly
4018 in normal SILC server. Affected file silcd/command.c.
4020 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Fixed GETKEY crash, it crashed if the command did not succseed.
4024 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4027 is now real and not just an macro interface to GMP.
4029 Removed the entire GMP from the source tree and imported new
4030 NSS MPI library instead. Reason for removing GMP is that it is
4031 extremely large and compiles extremely slow. The NSS MPI
4032 is only a few files and compiles in less than 10 seconds.
4033 The speed is also about the same as GMP. The MPI is imported
4034 to lib/silcmath/mpi.
4036 If the system has GMP installed we will still use the GMP.
4037 If it is not then the NSS MPI will be compiled.
4039 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Merged a long nickname (127 characters long) crash bugfix from
4042 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4044 * Merged a freed memory reference bugfix from Irssi CVS tree.
4045 Affected file irssi/src/core/commands.c.
4047 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4049 * Added the server's public key sving and verification to the
4050 server when performing the SKE. This was missing and the
4051 remote server's (or router's) public key was accepted without
4052 checking whether we have it previously or trust it at all.
4053 Affected file silcd/protocol.c.
4055 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Check in the silc_server_timeout_remote if protocol is active
4058 and make sure that the protocol's final callback is called so
4059 that all memory if freed. Affected file silcd/server.c.
4061 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * silc_server_whois_send_reply crashed the server if the nickname
4064 was 127 characters long. Affected file silcd/command.c.
4066 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Added sanity check to the silc_server_new_client. If the hostname
4069 is provided inside username then check that the provided hostname
4070 really is the same as the resolved one. If the hostname was not
4071 resolved then check it from the public key. Affected file is
4072 silcd/packet_receive.c.
4074 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4075 if the server disconnected us and the connection is not valid
4076 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4078 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4079 the library to the lib/silcutil/silcutil.[ch].
4081 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Close log file after open. Affected file
4084 lib/silcutil/silclog.c.
4086 * Check whether sock == NULL in silc_client_send_packet and return
4087 if it is. Affected file lib/silcclient/silcclient.c.
4089 * Check rec->entry == NULL in the Irssi SILC Client before
4090 sending the channel message. Affecte file is
4091 irssi/src/silc/core/silc-servers.c.
4093 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * Merged a splitted window bugfix from Irssi CVS tree. The
4096 affected file is irssi/src/fe-text/textbuffer-view.c.
4098 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4099 It did not print nickname.
4101 * Improved the distributions system a bit.
4103 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4106 irssi/src/fe-text/gui-window.c.
4108 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4109 to in-active server. The affected file is
4110 irssi/src/silc/core/client_ops.c.
4112 * Resolve the client in USERS command reply if the entry does
4113 not have username resolved. The affected file is
4114 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4115 command to WHOIS command to really resolve stuff. The USERS
4116 is not used any more in any critical section so WHOIS can
4117 be used even though it might be slower than IDENTIFY.
4119 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4122 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Changed the protocol API a bit more consistent in the
4125 lib/silccore/silcprotocol.[ch].
4127 * Changed the following headers to ROBODoc format:
4129 lib/silccore/silcpayload.h
4130 lib/silccore/silcprotocol.h
4131 lib/silccore/silcsockconn.h
4133 All core library headers are now formatted.
4135 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Fixed a bug in Irssi SILC client; do not show that you are
4138 server/router operator if you really are not. Affected file is
4139 irssi/src/silc/core/client_ops.c.
4141 * Renamed silc_command_free_payload to silc_command_payload_free.
4142 Affected file lib/silccore/silccommand.h
4144 * Added silcmath.h to include the prototoypes of various routines
4145 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4148 * Changed the following headers to ROBODoc format:
4150 lib/silccore/silcchannel.h
4151 lib/silccore/silccommand.h
4152 lib/silccore/silcid.h
4153 lib/silccore/silcidcache.h
4154 lib/silccore/silcmode.h
4155 lib/silccore/silcnotify.h
4156 lib/silccore/silcpacket.h
4157 lib/silcmath/silcmath.h
4159 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Added checking to the server code not to start the server if
4162 ciphers and stuff are not configured properly. Affected files
4163 silcd/serverconfig.[h] and silcd/server.c.
4165 * Changed the layout of the header files of the public interfaces
4166 in the SILC libraries. The new layout supports ROBODoc
4167 documentation tool (and some others) so that it is easy to create
4168 a library reference manual. All the other headers and source
4169 code must still follow the CodingStyle document. Also source
4170 code must not include these ROBODoc stuffs, only the headers.
4171 Furthermore, all public interface headers must now be named
4172 by using `silc' prefix, example: silcapi.h, silccipher.h.
4173 Some files were renamed due to this. All the other headers
4174 must not be used as public interfaces. I will update the
4175 CodingStyle document later. Changed following headers, so far:
4177 lib/silcclient/silcapi.h
4178 lib/silccore/silcauth.h
4179 lib/silccore/silcprivate.h
4180 lib/silccrypt/silcdh.h
4182 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Removed silc_client_packet_send_flush from the client library
4187 as it is not needed. Affected file lib/silcclient/client.[ch].
4189 * Added printing of message of unresolved authentication method
4190 to the Irssi SILC client. Added it to the module formats.
4191 Removed the same message from the client library.
4193 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Added new distribution feature, DISTLABEL. Every distribution
4196 can define own preprocessor label that can be used in the
4197 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4198 file distributions, acconfig.h.pre and prepare.
4200 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Added Makefile.defines_int to include the actual definitions
4203 for Makefile.defines.in. Tested the new distribution system,
4204 created distributions and tested installation.
4206 * Added AWAY message printing to the Irssi SILC client. Added
4207 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4209 * Added SCONNECT command to call the SILC's CONNECT command.
4210 Cannot use CONNECT directly since Irssi uses that internally.
4211 Affected file irssi/src/silc/core/silc-servers.c.
4213 Added ACTION local command. It is same as ME command but takes
4214 the channel as mandatory argument.
4216 Rewrote some of the Irssi's help files to suite for SILC
4219 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Added Makefile.defines[.in] that should for now on be included
4222 in all Makefile.am file in the source tree. That file includes
4223 all common compilation definitions for SILC source tree.
4225 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Minor changes to the ./prepare script to change the package
4228 name according the distribution name to the configure.in.
4230 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Created new distribution system. Added file `distributions'
4233 that defines all the distributions that can be created out of
4234 the SILC source tree. The ./prepare script now reads that
4235 file to determine how to prepare the distributions. The
4236 first argument to the ./prepare is the name of the distribution
4237 and second is the version of the distribution. If given
4238 without arguments it creates the default (toolkit) distribution
4239 with the default version (defined in ./prepare).
4241 All Makefile.am files that are subject to the distributions
4242 are now named as Makefile.am.pre. These are ./Makefile.am
4243 and lib/Makefile.am. Others may be changed later.
4245 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added invite list, ban list, some key management and connection
4248 error message printing to module formats in the Irssi SILC client.
4250 * Added new silc_client_set_away_message to set the away message
4251 that is back to the person who sent private message. The
4252 affected file lib/silcclient/silcapi.h and the
4253 lib/silcclient/client_prvmsg.c.
4255 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Fixed the private message sending in the Irssi SILC client,
4258 added local command KEY to the Irssi SILC client.
4260 Added key management and key agreement message formats to the
4261 irssi/src/fe-common/silc/module-formats.[ch].
4263 Added USERS (alias WHO) printing, server/router operator
4264 indication and LIST command printing to the module formats.
4266 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Fixed channel joining notify handling, cumode notify handling
4269 from Irssi SILC client.
4271 * Added SILC specific module-formats to the Irssi SILC client so
4272 that SILC specific message hilighting, colors etc is possible.
4273 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4275 Added channel mode, channel user mode, actions, notices,
4276 whois and whowas printing to the the module-formats.c.
4278 * Fixed a bug in channel deletion in the server. The channel
4279 is not left to the cache even if the channel founder auth mode
4280 is set when there are no users anymore on the channel. Affected
4281 file silcd/server.c.
4283 * The silc_net_localhost now resolves the entire hostname including
4284 the domain name. Affected file lib/silcutil/silcnet.c.
4286 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Changed the ask_passphrase client operation to be ascynchronous.
4289 It has now a completion callback and a context that the
4290 application must call after it has got the passphrase from
4291 the user. Affected files lib/silcclient/silcapi.h,
4292 lib/silcclient/protocol.c, lib/silcclient/command.c and
4295 Added SilcAskPassphrase callback that the application calls
4296 to deliver the passphrase to the library.
4298 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4299 The public key verification and especially a certificate
4300 verification is asynchronous procedure.
4302 Added new SILC_SKE_STATUS_PENDING status to indicate the
4303 request is pending and a callback will be called to finalize
4306 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4307 indicate that remote end did not send its public key (or
4308 certificate), even though we require it. Added check for this
4309 condition in the SKE. This was a security bug, now fixed.
4311 Defined new SilcSKEVerifyCbCompletion callback that is called
4312 when the verification process is completed.
4314 The affected files lib/silcske/silcske_status.h and
4315 lib/silcske/silcske.[ch].
4317 * Changed the verify_public_key client operation to be async
4318 as well. Defined SilcVerifyPublicKey callback that is used to
4319 indicate the success of the public key verification process.
4321 Changed the server and client to use the new async client
4324 * Changed the Irssi SILC client's internal scheduler to be called
4325 twice as many times as it used to be. As a result the client
4326 should be a bit faster now. Affected file is
4327 irssi/src/silc/core/silc-core.c.
4329 * Added support to Irssi SILC client of asynchronous public key
4330 verification and passphrase inquiry. Affected file is
4331 irssi/src/silc/core/silc-core.c.
4333 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Do not say "You have left channel %s" in client library.
4336 Moved it to the application. Affected files are
4337 lib/silcclient/command.c and silc/client_ops.c.
4339 * Fixed silc_client_get_clients. Command context was not
4340 duplicated and was freed memory in the callback. Affected
4341 file lib/silcclient/idlist.c.
4343 * Do not say "you are now talking..." on JOIN command in the
4344 client library. The appliation must handle it.
4346 * Do not say ".. changed topic to" in command reply in the
4347 client libary. The application must handle it.
4349 * Fixed TOPIC command sending in the client library.
4351 * Fixed a memory leak in silc_client_command_free in the file
4352 lib/silcclient/command.c.
4354 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Imported a modified version of Irssi client to the source tree.
4357 The Irssi will be used to create a new client called
4358 Irssi SILC. Imported to irssi/.
4360 Added silc_core_init_finish function to the Irssi. Affected
4361 file irssi/configure.in.
4363 A lot changes in the Makefile.ams around the irssi tree.
4365 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Do not rehash if the new size is same as the old size of the
4368 hash table, in the silc_hash_table_rehash*. The affected file
4369 lib/silcutil/silchashtable.c.
4371 * Replaced hash_table_del_by_context calls from the server
4372 (when channel->user_list and client->channels) to the
4373 hash_table_del as it is sufficient and faster.
4375 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Added silc_hash_table_list, silc_hash_table_get and the
4378 SilcHashTableList structure to provide an alternative way to
4379 traverse the hash table. The affected files are
4380 lib/silcutil/silchashtable.[ch].
4382 * Changed the server's idlist routines to use the hash table
4383 routines to optimize the code.
4385 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4387 * Replaced the client entry's `channel' list and channel entry's
4388 `user_list' list to hash tables for optimized lookup. Changed
4389 the code to use the hash table interface around the code.
4390 Affected file lib/silcd/idlist.[ch].
4392 * Added `auto_rehash' boolean argument to the function
4393 silc_hash_table_alloc to indicate whether the hash table should
4394 auto-rehash when it thinks is appropriate time. It will
4395 increase the hash table size if the there is twice as much
4396 entries in the table than the size of the table, and will
4397 decrease the size if there are twice as less entries than
4398 the size of the table.
4400 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4404 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * silc_idcache_purge_by_context deletes the entry now by context
4407 as it is supposed to do. Affected file lib/silccore/idcache.c.
4409 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4410 client is not anymore valid (WHOWAS givens the info) and not
4411 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4413 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Removed the `data' and `data_len' arguments from the ID Cache
4416 interfaces and added `name' argument. ID Cache does not handle
4417 anymore the binary data only a names associated with given ID.
4419 * When hashing a Client ID with silc_hash_id the entire ID is
4420 not hashed anymore, instead only the hash of the Client ID is
4421 hashed. This way we can access the Client ID from the cache
4422 with Client ID but with the hash of the ID (which is a hash of
4423 the nickname) as well without any difference in performance.
4425 Added also silc_idcache_find_by_id_one_ext to do one on one
4426 searching when we have the actual ID. Added also function
4427 silc_hash_client_id_compare. The affected files are
4428 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4430 * When hashing the name associated with a ID it is always done
4431 in lowercase. This way we can access the cache without worrying
4432 about case-sensitivity, even though, for example nicknames are
4435 * Fixed a bug in server with channel message sending. It put
4436 wrong ID type as destination ID. The affected file
4437 silcd/packet_send.c.
4439 * silc_idcache_del_by_context now deletes from all hash tables
4440 by context. Affected file lib/silccore/idcache.c.
4442 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Changed the client library to use the new ID Cache interface.
4445 Changes around the source tree.
4447 * Added silc_hash_table_rehash_ext to rehash with specific
4448 hash function. Affected file lib/silcutil/silchashtable.[ch].
4450 * Added silc_hash_string_compare to compare two strings in the
4451 hash table. Affected file lib/silcutil/silcutil.[ch].
4453 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Added new function silc_idcache_del_by_context into the
4456 lib/silccore/idcache.[ch].
4458 * Changed the server's ID list routines to use the new ID Cache
4459 interface. Changes around the source tree.
4461 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added silc_hash_table_del[_by_context]_ext functions in to the
4464 lib/silcutil/silchashtable.[ch].
4466 Removed silc_hash_table_find_all* routines and added new
4467 silc_hash_table_find_foreach to replace them.
4469 Added silc_hash_table_replace_ext function as extended
4470 replacing function. Separated the simple hash table interface
4471 from the extended hash table interface in the file
4472 lib/silcutil/silchashtable.h.
4474 * Fixed minor bugs and changed it to use some of the new
4475 hash table functions in lib/silccore/idcache.c
4477 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Added new function silc_hash_table_find_all to return all keys
4480 in the hash table by the specified key. As the hash table is
4481 collision resistant it also makes it possible to have several
4482 duplicate keys in the hash table. This function may be used to
4483 find all of the keys from the hash.
4485 Added user_context arguments to the SilcHashFunction,
4486 SilcHashCompare and SilcHashDestructor to deliver user specified
4489 Added new fuctions silc_hash_table_find[_all]_ext to do
4490 extended lookup with specified hash and compare functions and
4491 specified user contexts.
4493 Added new function silc_hash_table_add_ext to add the key
4494 with specified hash function and user context.
4496 Added new function silc_hash_table_foreach to traverse all
4497 entrys in the hash table. Added SilcHashForeach callback
4500 Added new function silc_hash_table_del_by_context to delete
4501 the entry only if the context associated with the key matches.
4503 Affected files are lib/silcutil/silchashtable.[ch].
4505 * Removed silc_hash_[server/client/channel]_id and added just
4506 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4507 silc_hash_id_compare to compare two ID's using as the hash table
4508 comparison function. Added also silc_hash_data to hash
4509 binary data and silc_hash_data_compare to compare it.
4511 * Removed silc_idlist_find_client_by_hash as it is not needed
4512 anymore. Affected file silcd/idlist.[ch].
4514 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4515 to use internally the SilcHashTable. The new ID Cache is a lot
4516 faster than the old one. Some of the ID Cache interface was also
4517 rewritten and obsolete and stupid functions were removed.
4519 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Added entry_count field to the SilcHashTable to keep the number
4522 of the entries in the table. Implemented the function
4523 silc_hash_table_rehash. Added new function
4524 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4526 Fixed a minor bug in silc_hash_table_free.
4528 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4529 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4530 into the lib/silcutil/silcutil.[ch].
4532 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Implemented a collision resistant hash table into the
4535 lib/silcutil/silchashtable[ch]. See the header and the source
4536 for the SilcHashTable API.
4538 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Merged dotconf version 1.0.2 into lib/dotconf.
4542 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Do not compile anything in lib/silcsim/* if the SIM support
4545 is not enabled. The tree should now compile without problems
4548 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Compiled the SILC under cygwin. Compiled and tested briefly
4551 without problems. More tests needed. The SIMs didn't compile
4554 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4556 * Fixed possible crash in silc_get_username in the
4557 lib/silcutil/silcutil.c.
4559 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Fixed a va_arg in silc/client_ops.c.
4563 * Oops, RC5 routines were named AES and caused some problems
4564 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4566 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added new SilcIDIP structure into the lib/silccore/id.h and
4569 replaced the old `ip' fields from all SILC ID's to that type.
4570 This is a step towards IPv6 support.
4572 The silc_id_get_len takes now the ID as an extra argument.
4573 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4574 both IPv4 and IPv6 based ID's.
4576 The affected files are lib/silccore/id.[ch] and other files
4577 around the tree using these routines.
4579 * Removed the ID length arguments in server from various
4580 silc_server_send_notify_* routines -> they are not needed
4583 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Fixed memory leak in silc_encode_pem_file in the file
4586 lib/silcutil/silcutil.c.
4588 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Check minor version as well in the SKE. Affected files are
4591 silcd/protocol.c and lib/silcclient/protocol.c.
4593 * Added --identifier option to the server so that an identifier
4594 can be when creating the public key for the server. Affected
4595 file is silcd/silcd.c.
4597 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4598 lib/silccrypt/silcpkcs.c.
4600 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Register default ciphers and stuff when using -C option with
4603 the server. Affected file sildc/silcd.c.
4605 * Put back the servers public key filename format, it is better
4606 than the new one. For now, the client keys are saved with the
4607 new filename format. The affected file silc/client_ops.c.
4609 * Implemented the Cipher API for the rest of the ciphers that
4610 did not implement it or implemented it the wrong way.
4612 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Register default ciphers and stuff when using the -S option
4615 in the client. Affected file silc/silc.c. Same also when
4616 creating new key pair with -C option.
4618 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Fixed the silc_verify_public_key client operation function to
4621 save the public keys differently. The fingerprint is now
4622 used as filename and not the hostname. This way also the
4623 client keys are saved uniquely and not with hostnames. The
4624 affected file is silc/client_ops.c.
4626 * Trimmed the silc_hash_fingerprint function to remove extra
4627 whitespaces from the end of the fingerprint. The affected
4628 file is lib/silccrypt/silchash.c.
4632 * Added silc_cipher_register_default function to register all
4633 default ciphers. It can be used when configuration files
4634 does not exist and the application does not want any specific
4635 ciphers in any specific order.
4637 The SilcDList is now used as silc_cipher_list dynamically
4638 allocated cipher list. Removed the static list all together
4639 and now all ciphers must be allocated to the dynamic list.
4640 The silc_cipher_alloc routine was changed to check only the
4643 All silc_cipher_* routines that used to return int returns
4646 The affected files lib/silccrypt/silccrypt.[ch].
4648 * The same thing was done to silc_hash_* as for silc_cipher_*
4649 routines. Affected files lib/silccrypt/silchash.[ch].
4651 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4652 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4653 Added also silc_pkcs_[un]register[_default] functions.
4654 Removed the data_context from the PKCS API.
4656 * Added silc_hmac_register_default function to register default
4657 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4658 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4659 to unregister all hmacs at once.
4661 * Register the default ciphers, hash functions, PKCSs and HMACs
4662 if client's configuration file does not exist. The affected
4665 * The client did not load the hash functions from the SIM
4666 modules at all. Added support for this. Affected file is
4667 silc/clientconfig.c.
4669 * When decoding public key with silc_pkcs_public_key_decode, check
4670 the supported algorithm only if PKCS are registered. Affected
4671 file lib/silccrypt/silcpkcs.c. The same was done with the
4672 silc_pkcs_private_key_decode.
4674 * Fixed the SILC List routines to keep the list always in order.
4675 It used to change the list's order when traversing the list but
4676 not it preserves the order. Affected file lib/trq/silclist.h.
4678 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Added the client library to use the SilcSocketConnection's
4681 reference counter (by silc_socket_dup) to prevent the bug that
4682 the socket object may be freed underneath async operation.
4684 * The name resolv library checking fixes in the configure.in.pre.
4687 * Created new version of the protocol drafts for future
4688 development. The -03 drafts are the ones that will be changed
4689 in the trunk now and the -02 will remain as they are.
4691 * Send list of CUMODE notifys to the router when announcing
4692 the channel users to the router. Affected file silcd/server.c.
4693 If the router receiving channel founder CUMODE for a channel
4694 that already has channel founder it will send CUMODE notify
4695 to the sender to remove the channel founder rights from the
4696 announced client. Affected file silcd/packet_receive.c.
4698 * The CUMODE notify may now use Server ID as well as the entity
4699 who changes the mode. Updated protocool specs.
4701 * Updated INSTALL and README files.
4703 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * New web pages in the http://silc.pspt.fi. The pages was
4710 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Implemented the [DenyConnectin] config section in the server.
4713 Added silc_server_config_denied_conn to check whether incoming
4714 connection is denied. Affected file silcd/serverconfig.[ch].
4716 * Do not check the ports when checking the incoming configuration
4717 data if the port is 0, meaning any. Affected file is
4718 silcd/serverconfig.c.
4720 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Fixed buffer overflow in silc_string_compare in the file
4723 lib/silcutil/silcutil.c.
4725 * Fixed double free in silc_server_command_leave in the file
4728 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Fixed the version checking in the server. Affected file is
4733 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Fixed the configuration data fetching when accepting new
4736 connections in the server. Affected file silcd/server.c.
4738 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added `sender_entry' argument to the function
4741 silc_server_packet_relay_to_channel so that we can check
4742 whether some destination actually belongs to the same route
4743 the sender belongs (ie, we must not resend the packet to the
4744 sender). Affected file silcd/packet_send.[ch].
4746 * Added `servername' field to the SilcClientEntry in the server
4747 to hold the name of the server where client is from. Affected
4748 file is silcd/idlist.h.
4750 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Moved the channel message encrypting in the router betwen
4753 router connections from silc_server_channel_message to the
4754 silc_server_packet_relay_to_channel since we want to check
4755 whether we have anybody channel before encrypting anything.
4756 Affected files silcd/packet_[receive/send].c.
4758 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Fixed the [AdminConnection] server config section to support
4761 multiple entries. Affected file silcd/serverconfig.c.
4763 * Added support into the server to check the validity of the
4764 incoming connection before executing any KE or authentication
4767 * The connection configuration is now saved to the KE and
4768 connection auth protocol contexts and not fetched anymore in
4769 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4771 * The local hosts listenning address and port is also resolved
4772 now when starting the server. We want to have the socket object
4773 to include the real address and port for the listener. Added
4774 new function silc_net_check_local_by_sock into the files
4775 lib/silcutil/silcnet.[ch].
4777 * Fixed a broadcast bug in server -> do not broadcast if we
4780 * Fixed a routing bug. Do not route broadcast packets ever.
4781 Broadcast packets must be processed always and not routed since
4782 they may be destined to some other host than yourself and thus
4783 would get routed without no good reason. Affected file is
4786 * Added function silc_server_config_is_primary_route to check
4787 whether primary router connection has been configured (a router
4788 configuration that we are initiating). If there is not, we
4789 will assume that there is only two routers in the SILC network
4790 and we will use the incoming router connection as our primary
4791 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4793 * Changed the order of the broadcasting. Broadcast _after_ the
4794 packet has been processed not before. Affected file is
4797 * Fixed a [ClientConnection] parsing bug. The port was never
4798 parsed correctly thus resulting to port 0. Affected file
4799 silcd/serverconfig.c.
4801 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4802 argument and did not set the broadcast packet flag. Affected
4803 file silcd/packet_send.c. Fixed same bug in the function
4804 silc_server_send_notify as well.
4806 * If we receive NEW_ID packet for our own ID in the server, ignore
4809 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Removed the nickname from the Private Message Payload.
4814 Updated the code and the protocol specs.
4816 * Updated protocol specs for submitting to the IETF.
4818 * Tweaked the Random Number Generator a bit. Affected file
4819 lib/silccrypt/silcrng.c. Exported a new function
4820 silc_rng_[global]_add_noise which can be used to add more
4823 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Do not parse packets with different timeout when protocol
4826 is active -> may cause problem with rekey. Affected file
4829 * When server receives signoff notify it must not create
4830 new channel key if the client is on any channels since the
4831 sender of the signoff notify will create it.
4833 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Added printing of error messages during SKE protocol from the
4836 failure packet sent by server during SKE. Affected file
4839 * Removed the client's failure_callback handling with timeout
4840 and handle it immediately when received.
4842 * The SKE library returned wrong type in SUCCESS and FAILURE
4843 packets. They must be 32 bit MSB not 16 bit MSB.
4845 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Ok, rewrote the logic of the re-key and now it seems to work.
4848 I tested it on high traffic with frequent re-keys without
4849 problems. Added hmac_receive (and renamed hmac to hmac_send)
4850 in SilcClientConnection in lib/silcclient/client.h and
4851 in SilcIDListData in silcd/idlist.h. Also, removed the
4852 SilcPacketParserContext's cipher and hmac fields as they are
4853 not needed anymore and actually caused some problems when
4854 the ciphers and hmac's changed underneath the packet parser.
4856 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * If re-key protocol is active then process the incoming packets
4859 synchronously since we must assure that icoming packets encrypted
4860 with the old key is processed before the new keys is set to
4861 use. This is true other packets than for REKEY packets.
4862 Affected file silcd/server.c. The same was done to client library
4863 as well, affected file lib/silcclient/client.c.
4865 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Fixed bug in client and server to accept the force send if
4868 the packet is send from silc_[server/client]_packet_process
4869 function. Otherwise the packets are never delivered, oops.
4871 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Disable force sending of packets when REKEY protocol is active.
4874 We must assure that no packet is sent directly when rekey is
4875 performed. All packets must be sent through packet queue.
4876 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4877 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4878 function is silc_[server/client]_packet_send_real to check
4881 * Replaced the SIM paths from example config files to
4882 /usr/local/modules. Also, make install creates now
4883 /usr/local/silc/logs directory to hold all the SILC server
4886 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Made the configure.in.pre work on Solaris. Patch by salo.
4890 * Made all ciphers compatible with non-x86 machines. Defined
4891 CBC mode macros into lib/silccrypt/ciphers_def.h.
4893 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Fixed the make install.
4897 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * When MAC computation fails the silc_packet_decrypt returned 0
4900 even though it was supposed to return -1. Fixed this. The
4901 affected file is lib/silccore/silcpacket.c.
4903 * Do not replace the config files in /etc/silc (in make install)
4904 if they already exist. Affected file ./Makefile.am.
4906 * Do not send re-key packets immediately but through packet queue.
4907 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4909 * Changed silc_net_check_host_by_sock to return FALSE if the
4910 IP/DNS could not be resolved. Though, it returns the IP address
4911 now even if it could not resolve it (but returns also FALSE).
4912 Affected file lib/silcutil/silcnet.[ch].
4914 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Added silc_pkcs_decode_identifier to decode the public key's
4917 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4918 Added also silc_pkcs_free_identifier. Added also new context
4919 SilcPublicKeyIdentifier.
4921 * Added -S option to the silc client. It is used to dump the
4922 contents of the specified public key file.
4924 * Changed the PKCS api to return the public key length when
4925 setting the public key.
4927 * Fixed a fatal bug in the public and private key file loading.
4928 Affected file lib/silccrypt/silcpkcs.c.
4930 * Execute the packet parsing for client with zero (0) timeout
4931 if the protocol is active. Affected file silcd/server.c.
4933 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Made the key generation options to the silcd program. Added
4936 -C option, equivalent to client's option.
4938 * Added new [ServerKeys] config section to the server. It
4939 configures the server's public and private key.
4941 * Defined generic Public Key Payload into the protocol
4942 specification to send specific type of public keys and
4945 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4946 public key or certificate.
4948 * Implemented the GETKEY command to the server and to the
4949 client library and on user interface.
4951 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Made preliminary `make install' work.
4955 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Added SilcServerRekey context into silcd/idlist.h.
4959 * Added the PFS support as defined in the specification to the
4960 SKE protocol. Affected files lib/silcske/*.c.
4962 * Added `ske_group' field to the SilcServerRekey context to hold
4963 the number of the SKE group that is used with PFS in re-key.
4964 Affected file silcd/idlist.h.
4966 * Added PFS re-key support to the server. Affected file is
4969 * Added silc_protocol_cancel to cancel execution of the next
4970 state of the protocol. Affected file is
4971 lib/silccore/silcprotocol.[ch].
4973 * Added the re-key support with and without PFS to the client
4974 library. Re-key is performed once in an hour, by default.
4976 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4977 Added silc_client_rekey_callback and silc_client_rekey_final.
4978 Affected files are lib/silcclient/protocol.[ch] and
4979 lib/silcclient/client.[ch].
4981 * Removed the `hmac_key' and `hmac_key_len' fields from the
4982 SilcClientConnection structure; not needed. Affected file is
4983 lib/silcclient/client.h.
4987 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Do not ask whether user wants to use the negotiated private key
4990 for private messages, just use it. Affected file is
4991 silc/local_command.c.
4993 * Added `send_enc_key' and `enc_key_len' fields to the
4994 SilcIDListData structure since they are needed in the re-key
4995 phase. Affected file is silcd/idlist.[ch].
4997 * Implemented the simple re-key protocol into the server.
4998 Affected files silcd/server.c and silcd/protocol.[ch]. The
4999 re-key will be performed once in an hour, by default.
5001 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5002 Added silc_server_rekey, silc_server_rekey_callback and
5003 silc_server_rekey_final.
5005 * Removed Tunneled flag from the protocol. Updated the code
5006 and the specifications.
5008 * Adde `pfs' field to the SilcIDListData to indicate whether
5009 the PFS is to be performed in the re-key. Affected file is
5012 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5015 int64 of at least the xintXX size. If void * is less that 4
5016 bytes uint32 * will be used. Defined bool as boolean.
5018 * Changed _ALL_ unsigned long and unsigned int to uint32,
5019 unsgined short to uint16 in the source tree.
5021 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5022 not handle clients that has entry->data.registered == FALSE.
5023 They are not in the network anymore. Affected file is
5026 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5028 * Implemented the sending of the SERVER_SIGNOFF notify in the
5029 server. Affected file is silcd/server.c.
5031 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5032 Added also silc_notify_payload_encode_args into the
5033 lib/silccore/silcnotify.[ch].
5035 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5036 Affected file silcd/packet_receive.c.
5038 * Implemented the SERVER_SIGNOFF notify handling in the client
5039 library. Affected file lib/silcclient/client_notify.c. Also,
5040 implemnted the printing of the SERVER_SIGNOFF info to the
5041 application. Affected file silc/client_ops.c.
5043 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5044 if the deleting was successful. Affected file silcd/idlist.[ch].
5046 * Added support for public key authentication in the connection
5047 authentication protocol in the client library. Affected file
5048 lib/silcclient/protocol.c.
5050 * Changed the server's silc_idlist_get_clients_by_* interface
5051 to support already allocated array so that new entries may be
5052 added to pre-allocated array. Affected file silcd/idlist.[ch].
5053 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5054 and command replies.
5056 * All command reply functions in the server now calls the
5057 pending command callback even if error occured. This way the
5058 error will be delivered to the client as well. Affected files
5059 silcd/command.c and silcd/command_reply.c.
5061 * Fixed INFO command to return local server's info if no server
5062 was provided. Affected file lib/silcclient/command.c.
5064 * Removed RESTART command for good. Updated the code and the
5067 * Rewrote parts of the task system. It is a bit simpler now.
5068 Removed unsued task priorities. The affected files are
5069 lib/silcutil/silctask.[ch].
5071 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Moved the USERS printing from the library to the application.
5074 Affected files lib/silcclient/command.c and silc/client_ops.c.
5076 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Added channel key re-key support. The re-key is perfomed
5081 only by the router and is done once in an hour. Added `rekey'
5082 field to the SilcChannelEntry in the server. Affected files
5083 silcd/server.c and silcd/idlist.h.
5085 * Added silc_task_unregister_by_context into the file
5086 lib/silcutil/silctask.[ch].
5088 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Added SILC_UMODE_GONE mode to indicate when the client is not
5091 present in the SILC network. Added also support to the local
5092 command AWAY that will set this mode. Added support of showing
5093 "xxx is gone" in WHOIS command. The USERS command shows the
5094 gone status as well.
5096 * Fixed setting server and router operator privileges in the
5097 server's UMODE command. Affected file silcd/command.c.
5099 * Merged the SKE KE1 and KE2 payloads into one payload. The
5100 new KE payload is equivalent to the old KE2 payload.
5102 Cleaned up the SKE Start Payload parsing. It now uses the
5103 simple buffer unformatting to do the parsing. A lot faster
5106 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5107 to the SKE that is used to indicate whether both of the SKE
5108 parties should perform authentication. By default only the
5109 responder performs authentication. By setting this flag also
5110 the initiator must do authentication. By default it is unset
5111 since in normal SKE case, client to server connection, only
5112 the responder should do authentication. When doing SKE between
5113 two clients both should perform authentication. Updated the
5114 code and the protocol specs.
5116 * A little fix to IDENTIFY command in the server. Search the
5117 client first by hash not nickname. Affected file is
5120 * Fixed the silc_client_close_connection to support closing
5121 the client to client connections wihtout deleting too much
5122 data. Affected file lib/silcclient/client.c.
5124 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5125 are received if protocol used to be active but is not anymore
5126 the application would crash due to NULL pointer dereference.
5127 Affected files silcd/server.c and lib/silcclient/client.c.
5129 * Added `hash' field to the SilcClientConnection to include
5130 the hash function negotiated in the SKE protocol.
5132 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5133 to set the channel founder authentication data. A client can
5134 claim the founder rights later by providing the authentication
5135 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5136 This way the channel founder can regain the channel founder
5137 privileges even it is left the channel. This works only on
5138 local server and the client must be connected to the same
5139 server to be able to regain the founder rights. Updated the
5140 protocol specs accordingly.
5142 Added support to the CMODE command in the client to set the
5143 founder auth data. Read the README to see how to set it.
5145 Added support to the CUMODE command to claim the founder
5146 rights. Read the README to see how to do it.
5148 Added support for the founder authentication to the Channel
5149 Entry in the server. Affected file silcd/idlist.h.
5151 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5152 server's CMODE command. Affected file silcd/command.c.
5154 * Added the following new functions into lib/silccore/silcauth.[ch]:
5155 silc_auth_get_method and silc_auth_get_data.
5157 * The server now saves the remote hosts public key to the
5158 SilcIDListData pointer. Affected file silcd/protocol.c.
5160 * The normal server now does not remove the channel entry from
5161 the cache if the founder authentication data is set. It used
5162 to remove it if the founder was the last one on the channel on
5163 the server and left the channel. The auth data is saved and
5164 if the channel is re-joined later the old entry is used with
5165 the old auth data. Affected files silcd/command_reply.c and
5168 * Removed the `pkcs' field from the SilcIDListData structure
5169 in the server; it is not used. Affected file silcd/idlist.h.
5171 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Fixed packet processing on slow links. Partial packets were
5174 never re-processed because the incoming data buffer was cleared
5175 by the application. Application must not directly clear the
5176 sock->inbuf, the packet processing routines handle it. Fixed
5177 this in client library and in server.
5179 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Fixed the WHOIS and IDENTIFY send reply function to really
5182 check whether to send list or just one entry. Affected file
5185 * Cleaned up the LEAVE command's channel key distribution. The
5186 affected file silcd/command.c.
5188 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5189 can enforce the channel mode as well. In that case the ID
5190 includes the ID of the server. The code now enforces the
5191 mode change if the router have different mode than the server.
5193 * The notify client operation with CMODE_CHANGE notify can now
5194 return NULL client_entry pointer if the CMODE was not changed
5195 by client. Application must check for this.
5197 * Added <Server ID> argument to INFO command to support server
5198 info fetching by Server ID.
5200 * Added silc_server_announce_get_channel_users to get assembled
5201 packets of channel users of the specified channel. Affected
5202 file silcd/server.[ch].
5204 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5205 was freed underneath the ID Cache.
5207 * Re-announce clients when the server received CHANNEL_CHANGE
5208 notify from the router. Affected file silcd/packet_send.c.
5210 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5213 crashed since it did not handle the fact that there is no cipher
5214 called "3" and didn't check the error condition. Now fixed.
5216 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5217 flag. It can be used to send message requests.
5219 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Implemented the RESTART command in the client.
5223 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5224 notice type messages. Added notice printing to the user
5227 * The channel keys are not re-generated if the channel's mode
5228 is PRIVKEY, ie private key on the channel exists. Affected
5229 files silcd/server.c and silcd/command.c.
5231 * Fixed a little bug in channel message delivery when channel
5232 private keys are set in the server. Affected file is
5233 silcd/packet_send.c.
5235 * Changed the setting on channel->on_channel = TRUE from the
5236 silc_client_save_channel_key to the JOIN command reply. The
5237 key payload is not received if the private channel key is set.
5238 Affected file lib/silcclient/command_reply.c and the
5239 lib/silcclient/client_channel.c.
5241 * When the CMODE_CHANGE notify is sent and the channel private
5242 key mode is removed the channel key must be re-generated in
5243 other cells as well. Added this support for the router in the
5244 silcd/packet_receive.c.
5246 * Added new local command NOTICE to send notice message on
5247 channel. Affected file silc/local_command.[ch].
5249 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Added new local command ME to the client. It is used to send
5252 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5253 some action. Affected file silc/local_command.[ch].
5255 * Changed channel_message and private_message client operations
5256 to deliver the message flags to the application. Added also
5257 the `flags' arguments to the silc_client_send_channel_message
5258 and silc_client_send_private_message functions. Affected file
5261 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5263 * Redefined the Private Message Payload to support private message
5264 keys and to support the new private message flags. Updated
5265 the protocol specs. Flags makes it possible to have for example
5266 CTCP style messages.
5268 * Added new type SilcPrivateMessagePayload and defined an API
5269 for it in the lib/silcclient/silcprivate.[ch].
5271 * Tested private message private keys successfully. Tested the
5272 private message key set, unset and list commands with the new
5275 * Redefined the Channel Message Payload to include the channel
5276 message flags (equal with private message flags) to support
5277 for example CTCP style messages.
5279 * Defined some of the message (for channel and private message)
5280 flags. Updated the protocol specs and added the flags to the
5281 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5283 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Added SilcKeyAgreementStatus type to the key agreement routines
5286 to indicate the current status and error if one occured.
5287 The status types are defined in the lib/silcclient/silcapi.h.
5289 * Added new local command KEY that is used to set and unset private
5290 keys for channels, set and unset private keys for private messages
5291 with remote clients and to send key agreement requests and
5292 negotiate the key agreement protocol with remote client. The
5293 key agreement is supported only to negotiate private message keys,
5294 it currently cannot be used to negotiate private keys for channels,
5295 as it is not convenient for that purpose.
5297 * Fixed a minor pending callback setting bug in the function
5298 silc_client_get_client_by_id_resolve, now the function works.
5299 Affected file lib/silcclient/idlist.c.
5301 * Added function silc_net_get_local_port to get local bound
5302 port by socket. Added to lib/silcutil/silcnet.[ch].
5304 * Added `sockets' and `sockets_count' fields to the SilcClient
5305 object. They hold the sockets of the listenning sockets in
5306 the client. Listenning sockets may be for example the key
5307 agreement server. Affected file lib/silcclient/client.[ch].
5308 Added functions the silc_client_add_socket and the
5309 silc_client_del_socket. They are exported to the application
5312 * Added ~./silc/clientkeys to support other client's public keys.
5314 * Renamed verify_server_key client operation to verify_public_key
5315 and added one argument to indicate the type of the connection
5316 (server, client etc.).
5318 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Added silc_server_connection_auth_request to handle the
5321 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5322 silcd/packet_receive.[ch].
5324 * Added silc_server_send_connection_auth_request into the
5325 silcd/packet_send.c to send the connection auth request packet.
5327 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5330 * Fixed the public key authentication in responder side in the
5331 server. The `auth_data' pointer includes the SilcPublicKey
5332 not the path to the public key. Affected file silcd/protocol.c.
5334 * Implemented the public key authentication in the initiator side
5335 in the server. Affected file silcd/protocol.c.
5337 * Removed the [RedirectClient] config section from the server
5338 configuration. Is not needed and I don't want to implement it.
5340 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Cleaned up the CMODE command in the server. It now works
5343 correctly and supports all the modes defined in the protocol.
5344 Affected file is silcd/command.c.
5346 * Added `hmac_name' field to the SilcChannelEntry in the server
5347 to hold the default HMAC of the channel. It can be set when
5348 creating the channel (with JOIN command). Affected files
5351 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5352 type to indicate the change of the current cipher and hmac
5353 on the channel. Client can safely ignore the <cipher> argument
5354 (if it chooses to do so) since the CHANNEL_KEY packet will
5355 force the channel key change anyway. The <hmac> argument is
5356 important since the client is responsible of setting the new
5357 HMAC and the hmac key into use.
5359 * Fixed the CMODE command in the client library as well.
5361 * Tested CMODE command in router environment successfully.
5363 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Show the version of the remote client (or server) when connecting
5366 to the server. It is logged to the log file. Affected file
5367 is silcd/protocol.c.
5369 * Fixed the KILLED notify handling in the client library. The
5370 client must be removed from all channels when receiving the
5373 Also, do not remove the client entry when giving the KILL
5374 command but when the KILLED notify is received.
5376 * Removed silc_idlist_find_client_by_nickname from the server.
5377 Not needed anymore. Affected files silcd/idlist.[ch].
5379 * Implemented the CHANNEL_CHANGE notify type handling to the
5380 server. Affected file silcd/server.c.
5384 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Added silc_server_send_notify_invite to send the INVITE
5387 notify between routers.
5389 * Implemented the INVITE command correctly to the server.
5391 * Implemented the INVITE notify type handling in the server.
5393 * Implemented the INVITE command to the client library and on the
5396 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Added function silc_server_get_client_resolve to find the
5399 client entry by ID from all ID lists and then resolve it
5400 (using WHOIS) if it cannot be found. Affected file is
5403 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Implemented the BAN command to the client library.
5407 * The JOIN command in the server now checks the invite list
5410 * Changed the silc_command_reply_payload_encode_va and the
5411 silc_command_payload_encode_va to support that if argument is
5412 NULL it ignores and checks the next argument. Affected file
5413 lib/silccore/silccommand.c.
5415 * Added silc_server_send_notify_ban to send the BAN notify
5416 type between routers.
5418 * Chaned the silc_notify_payload_encode to support that if
5419 argument is NULL it ignores and checks the next argument.
5420 Affected file lib/silccore/silcnotify.c.
5422 * Tested ban lists in router environment successfully.
5424 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Implemented BAN command to the server, in silcd/command.[ch].
5428 * Removed the BAN and INVITE_LIST modes from the CMODE command
5431 * Added function silc_string_match to regex match two strings.
5432 Affected files lib/silcutil/silcutil.[ch].
5434 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Redefined parts of the SilcChannelEntry in the server to support
5437 the new ban and invite lists.
5439 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Redefined the INVITE command. The same command can be used to
5442 invite individuals to the channel but also to manage the invite
5443 list of the channel (to add to and remove from the invite list).
5444 Updated the protocol specs.
5446 * Added new command SILC_COMMAND_BAN that can be used to manage
5447 the ban list of the channel. Updated the protocol specs.
5449 * Removed the channel modes: the SILC_CMODE_BAN and the
5450 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5451 in the CMODE command. The equivalent features are now available
5452 using INVITE and BAN commands. Updated the protocol specs.
5454 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5455 in the network about change in the current ban list. The notify
5456 type is not used by the client.
5458 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5459 support the invite lists.
5461 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Added new function silc_string_regexify that converts string
5464 including wildcard characters into regex string that can
5465 be used by the GNU regex library. Added into the file
5466 lib/silcutil/silcutil.[ch].
5468 Added silc_string_regex_combine to combine to regex strings
5469 into one so that they can be used as one regex string by
5470 the GNU regex library. Added into the file
5471 lib/silcutil/silcutil.[ch].
5473 Added silc_string_regex_match to match two strings. It returns
5474 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5476 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Imported GNU regex to the soruce tree into lib/contrib.
5479 Fixed some compiler warning from the regex.c.
5481 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Fixed MOTD command in the server to work in router environment.
5485 * Fixed the MOTD command in the client library to support
5486 the server argument in the command.
5488 * Added `nickname_len' argument to the silc_idlist_add_client
5489 in the server, as the `nickname' argument may be binary data
5492 * Added silc_idlist_get_channels to return all channels from
5495 * Implemented LIST command to the server. Affected file is
5498 * Implemented the LIST command to the client library and on the
5501 * Added [<user count>] argument to the LIST command reply.
5502 With private channels the user count is not shown.
5504 * Updated TODO and README.
5506 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * The client entry's data.registered must be TRUE even with
5509 global client entry on global client list. The data.registered
5510 is used to check whether the client is anymore in the network,
5511 for example with WHOWAS command so it must be valid.
5513 * Fixed the WHOWAS command in the server. It now actually works
5514 in router environment. Added function into silcd/command_reply.c
5515 silc_server_command_reply_whowas_save.
5517 * Added silc_idlist_purge function to the silcd/idlist.c
5518 to periodically purge the ID Cache.
5520 * Fixed INFO command in the server. It works now in router
5521 environment. Added <server name> argument to the INFO command
5522 reply. Updated the protocol specs.
5524 * Fixed minor bug in silc_idcache_purge to not purge if the
5525 expire value is zero.
5527 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5528 they were buggy because of the WHOWAS information.
5530 * Fixed local command MSG to handle the async resolving of
5531 the remote client properly. It used to fail the first MSG.
5532 Affected file silc/local_command.c.
5534 * Added `data_len' field to SilcIDCache context.
5536 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Update TODO. Todo in commands in the server.
5540 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5543 used by routers as broadcast packet to inform other routers
5544 about the changed user mode.
5546 Implemented the notify handling in the server. Affected file is
5547 silcd/packet_receive.c. Added the function
5548 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5550 * Added new generic Channel Payload and deprecated the New Channel
5551 Payload. The New Channel Payload is now the generic Channel
5554 * Added new argument `mode' to the silc_server_send_new_channel
5555 as it is required in the Channel Payload now.
5557 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5558 and created a new and real SilChannelPayload to represent the
5559 new generic Channel Payload. Implemented the encode/decode
5560 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5562 * Added silc_server_get_client_channel_list to return the list
5563 of channels the client has joined for WHOIS command reply.
5564 Affected file silcd/server.[ch].
5566 * Implemented the channel list sending in the WHOIS command reply
5567 in server and in the client.
5569 Implemented the channel list displaying on the user interface
5570 as well. Affected file silc/client_ops.c.
5572 * Added silc_channel_payload_parse_list to parse list of Channel
5573 Payloads. It returns SilcDList list of SilcChannelPayloads.
5574 Client for example can use this function to parse the list of
5575 channels it receives in the WHOIS command reply. The caller
5576 must free the list by calling silc_channel_payload_list_free.
5577 Affected files lib/silccore/silcchannel.[ch].
5579 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Added one new argument <user mode> to the WHOIS command reply
5582 to return the mode of the user in SILC. Updated the protocol
5585 Implemented it to the server and client.
5587 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Fixed the mode printing on the user interface on joining.
5590 Affected file silc/client_ops.c.
5592 * Implemented the UMODE command and user modes in general to the
5593 client library and to the user interface.
5595 * Implemented the UMODE command to the server.
5597 * The server now sends UNKNOWN_COMMAND error status if client sends
5598 unknown command. Affected file silcd/command.c.
5600 * All server commands now handle the command identifier the right
5601 way when sending the command reply to the client. The client can
5602 use to identify the command replies with the identifier.
5604 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Added silc_server_get_client_route to resolve the route to
5607 the client indicated by the client ID. Affected file is
5610 * Added silc_server_relay_packet as general function to relay
5611 packet to arbitrary destination. This deprecates functions
5612 like _send_private_message_key, _relay_notify etc. Affected
5613 file is silcd/packet_send.[ch].
5615 Removed silc_server_send_key_agreement,
5616 silc_server_send_private_message_key and
5617 silc_server_packet_relay_notify functions from the file
5618 silcd/packet_send.[ch].
5622 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5623 server. Affected file silcd/packet_receive.[ch].
5625 * Implemented the KILL command to the client. Implemented the
5626 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5627 Affected files lib/silcclient/command[_reply].c and
5628 lib/silcclient/client_notify.c. Implemented the KILL notify
5629 printing in the user inteface.
5631 * Fixed a lot silc_parse_nick memory leaks from the client
5632 library in the file lib/silcclient/command.c.
5634 * Changed the silc_server_send_notify_on_channels's `sender'
5635 argument from SilcSocketConnection to SilcClientEntry to
5636 check the sender as entry and not as connection object and not
5637 to send to the client provided as argument. The affected file
5638 is silcd/packet_send.[ch].
5640 * The notify packets that are destined directly to the client used
5641 to not to be processed by the server. Now changed that and the
5642 server processes all notify packets. After relaying the packet
5643 to the client the notify packet is processed in the server.
5645 * The silc_server_free_client_data now checks whether there is
5646 pending outgoing traffic for the client and purges the data to
5647 the network before removing the client entry.
5649 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5652 an client is killed from the SILC Network. Updated the protocol
5655 Added new function silc_server_send_notify_killed to the
5656 silcd/packet_send.[ch].
5658 * Added function silc_server_packet_relay_notify to relay notify
5659 packets that are destined directly to a client. In this case
5660 the server does not process the notify packets but merely relays
5661 it to the client. Affected file silcd/packet_send.[ch].
5663 Added also silc_server_packet_process_relay_notify to check
5664 whereto relay the notify. Affected file is
5665 silcd/packet_receive.[ch].
5667 * Implemented the KILL command to the server.
5671 * Added the backup schema desgined last fall to the protocol
5672 specs for everyone to see. The specification is in the
5673 *-spec-xx.txt draft and the packet type definitions for the
5674 backup routers is in *-pp-xx.txt draft. Thusly, added also
5675 new packet type SILC_PACKET_CELL_ROUTERS.
5677 * A big security problem in the implementation discovered. The
5678 signoff of an client did not cause new channel key generation
5679 which it of course should've done. The channel keys must be
5680 always re-generated when client leaves (or signoffs) the channel.
5681 The silc_server_remove_from_channels funtion now handles
5682 the channel key re-generation.
5684 * Added `sender' argument to the silc_server_send_notify_on_channels
5685 to not to send the client provided as argument. Affected file
5686 silcd/packet_send.[ch].
5688 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Implemented OPER and SILCOPER commands into the server and
5693 * Added silc_auth_verify and silc_auth_verify_data to verify
5694 the authentication directly from the authentication payload.
5695 It supports verifying both passphrase and public key based
5696 authentication. Affected file lib/silccore/silcauth.[ch].
5698 * Added `hash' field to the SilcIDListData structure. It is the
5699 hash negotiated in the SKE protocol. Affected file is
5702 * Slight redesigning of the SilcAuthPayload handling routines.
5703 Do not send SilcPKCS but SilcPublicKey as argument.
5705 * Implemented the public key authentication support to the
5706 serverconfig. The public key is loaded from the provided path
5707 and saved as authentication data to void * pointer. Thus,
5708 changed the unsigned char *auth_data to void *auth_data;
5710 * Fixed SHUTDOWN command to send the reply before the server
5711 is shutdown. :) Affected file silcd/command.c.
5713 * Fixed fatal bug in CONNECT command. The hostname was invalid
5714 memory and server crashed. Affected file silcd/command.c.
5716 * Fixed fatal bug in CLOSE command. The server_entry became
5717 invalid but was referenced later in the command. Affected file
5720 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Fixed fatal bug in failure packet handling. Server ignored
5723 the failure and thus crashed when it came.
5727 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5730 that the command may be executed only once in (about) 2 seconds.
5731 The old SILC_CF_LAG flag is same but allows command bursts up
5732 to five before limiting.
5734 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5735 server code. Various commands now includes the CF_LAG_STRICT
5736 flag to disallow any kind of miss-use of the command.
5738 * Fixed the silc_buffer_unformat to not to allocate any data
5739 if the length of the data is zero. It used to allocate the
5740 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5742 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Changed the format of AdminConnection configuration section
5745 in the server. Added username of the admin to the format.
5746 Affected files silcd/serverconfig.[ch].
5748 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5749 to return admin configuration data by host, username and/or
5752 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Implemented WHOWAS command to the server. Added the functions:
5756 silc_server_command_whowas_parse,
5757 silc_server_command_whowas_send_reply,
5758 silc_server_command_whowas_from_client and
5759 silc_server_command_whowas_from_server
5761 * Added <Client ID> argument to the WHOWAS command reply. Updated
5762 the protocol specs accordingly.
5764 * Implemented WHOWAS command and command_reply to the client
5767 Implemented the WHOWAS printing on the user interface.
5769 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added new argument to the WHOWAS command reply, the real name.
5772 It is an optional argument. Updated the protocol specs.
5774 * Added SilcIDCacheDestructor callback that is registered when
5775 the SilcIDCache is allocated. The callback is called when
5776 an cache entry in the ID Cache expires, or is purged from the
5777 cache. Added into lib/silccore/idcache.[ch].
5779 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5780 to destruct the client entries when the cache entry expires.
5781 Other ID Cache's in server and in the client library ignores
5784 * If the ID Cache entry's `expire' field is zero then the entry
5785 never expires. Added boolean `expire' argument to the
5786 silc_idcache_add function in the lib/silccore/idcache.[ch].
5787 If it is TRUE the default expiry value is used.
5789 * Added silc_server_free_client_data_timeout that is registered
5790 when client disconnects. By default for 5 minutes we preserve
5791 the client entry for history - for WHOWAS command.
5793 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Added support to the server to enforce that commands are not
5796 executed more than once in 2 seconds. If server receives
5797 commands from client more frequently, timeout is registered
5798 to process the commands. Affected file silcd/command.c.
5799 Added new function silc_server_command_process_timeout.
5801 * Changed NICK_NOTIFY handling in client library to check that
5802 if the client's nickname was changed, so there is no need to
5803 resolve anything from the server.
5805 * Removed error printing from the WHOIS and IDENTIFY commands.
5806 If error occurs then it is ignored silently in the client library.
5807 The application, however, may map the received error to
5808 human readable error string. The application currently maps
5809 the NO_SUCH_NICKNAME error to string.
5811 * Made the command status message public to the application. Moved
5812 them from lib/silcclient/command_reply.c to
5813 lib/silcclient/command_reply.h. The application can map the
5814 received command status to the string with the
5815 silc_client_command_status_message function.
5817 * Added check to the server to check that client's ID is same
5818 as the Source ID in the packet the client sent. They must
5821 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5823 * Added dist-bzip hook to the Makefile.am to make bzip2
5824 compressed distributions.
5826 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Server now enforces the maximum length for the nickname and
5829 the channel as protocol specification dictates. 128 bytes for
5830 nickname and 256 bytes for channel name.
5832 * Moved the WHOIS printing to the application. The client libary
5833 does not print out the WHOIS information anymore, the application
5834 must do it. Renamed silc_client_command_reply_whois_print to
5835 the silc_client_command_reply_whois_save.
5837 The client's idle time is also sent to the application now, and
5838 the idle is shown on screen.
5840 * Added silc_client_command_reply_identify_save to save the
5841 received IDENTIFY entries.
5843 * Do not check for channel private keys in message sending and
5844 reception if the channel does not have the PRIVKEY mode set.
5845 Affected file lib/silclient/client_channel.c.
5847 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5850 just surfaced after chaning the JOIN procedure.
5852 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Added silc_client_get_clients_by_list to get client entries
5855 from Client ID list, that is returned for example by JOIN
5856 and USERS command replies. The application should use this
5857 function for example when JOIN command reply is received to
5858 resolve the clients already on the channel (library does not
5859 do that anymore as USERS command reply is not used in the JOIN
5860 procedure anymore). Affected files lib/silcclient/silcapi.h and
5861 lib/silcclient/idlist.c.
5863 * JOIN command reply and USERS command reply returns now SilcBuffer
5864 pointers instead of unsigned char pointers when returning
5865 the client list and mode list.
5867 * Added <Client ID> argument to the JOIN command reply, mainly
5868 for the server to identify for which client the command was
5869 originally sent. Updated protocol specs accordingly.
5871 * Added SilcDlist private_key pointer to the SilcChannelEntry
5872 in the client to support the channel private keys. Affected
5873 file is lib/silcclient/idlist.h.
5875 * Added SilcChannelPrivateKey argument to the function
5876 silc_client_send_channel_message so that application can choose
5877 to use specific private ke if it wants to. If it is not provided,
5878 the normal channel key is used, unless private keys are set.
5879 In this case the first (key that was added first) is used
5880 as the encryption key.
5882 * Implemented the support for channel private key handling.
5883 Implemented the following functions:
5885 silc_client_add_channel_private_key,
5886 silc_client_del_channel_private_keys,
5887 silc_client_del_channel_private_key,
5888 silc_client_list_channel_private_keys and
5889 silc_client_free_channel_private_keys
5891 Affected file lib/silcclient/client_channel.c.
5893 * Added the support for the private keys in the channel message
5894 sending and encryption and in the message reception and
5895 decryption. Affected funtions are
5896 silc_client_send_channel_message and silc_client_channel_message.
5898 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Added SKE's key verify callback to the client library's
5901 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5903 * Removed the statement that server (or router) must send USERS
5904 command reply when joining to the channel so that the client
5905 knows who are on the channel. Instead, the client list and
5906 client's mode list is now sent in the JOIN command reply to the
5907 client who joined channel. This is better solution.
5909 * Added function silc_server_get_users_on_channel and function
5910 silc_server_save_users_on_channel to the silcd/server.[ch].
5912 * Removed function silc_server_command_send_users from the
5915 * Do not show topic on the client library anymore. The topic is
5916 sent in the command reply notify to the application and the
5917 application must show the topic now.
5919 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added client searching by nickname hash into the IDENTIFY and
5922 WHOIS commands in the server as they were clearly missing from
5923 them. Affected file is silcd/command.c.
5925 * Fixed a bug in private message receiving in the client library.
5926 The remote ID was freed and it wasn't supposed, now it is
5929 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Minor fix to the channel payload; allocate the data area, as it
5932 needs to be of specific length.
5934 * If the key agreement port is zero then the operating
5935 system will define the bound port. Affected files are
5936 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5938 * Added new function silc_channel_payload_decrypt into the file
5939 lib/silccore/silcchannel.[ch].
5941 * Moved the channel message etc, check from silc_packet_decrypt
5942 to applications. The library calls now a generic
5943 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5944 when the packet is either normal or special. This was done to
5945 allow more wide range of checking that was not allowed when
5946 the code was in library. Now applications can do virtually any
5947 checks to the packet and return to the library the decision how
5948 the packet should be processed. Affected files are
5949 lib/silccore/silcpacket.[ch].
5951 Added silc_server_packet_decrypt_check to the server and
5952 silc_client_packet_decrypt_check to the client library.
5954 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5955 to send with specified source and destination information.
5957 * Channel message delivery between routers was broken after the
5958 channel key distribution was fixed earlier. The channel key
5959 was used be to distributed to other routers as well which is not
5960 allowed by the protocol. Now this is fixed and channel keys
5961 really are cell specific and the channel message delivery between
5962 routers comply with the protocol specification.
5964 * Fixed various commands in server to check also the global list
5965 for the channel entry and not just the local list. The affected
5966 file silcd/command.c.
5968 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Added assert()s to buffer formatting and unformatting routines
5971 to assert (if --enable-debug) when error occurs. Affected
5972 file: lib/silcutil/silcbuffmt.c.
5974 * Changed to auto-reconnect to check whether the remote host is
5975 router and register the re-connect timeout if it is. It used
5976 to check that whether we are normal server, but router must do
5977 auto-reconnect with another router as well. Affected file
5980 * Removed the [<key len>] option from CMODE command as the cipher
5981 name decides the key length, nowadays. See the defined ciphers
5982 from the protocol specification.
5984 * Added [<hmac>] option to the CMODE command to define the HMAC
5985 for the channel. Added SILC_CMODE_HMAC channel mode.
5987 * Added [<hmac>] option for the JOIN command so that user can
5988 select which HMAC is used to compute the MACs of the channel
5991 * Added Hmac field to the Channel Message Payload. The integrity
5992 of plaintext channel messages are now protected by computing
5993 MAC of the message and attaching the MAC to the payload. The
5994 MAC is encrypted. Now, it is clear that this causes some
5995 overhead to the size of the packet but rationale for this is that
5996 now the receiver can verify whether the channel message decrypted
5997 correctly and also when private keys are set for the channel the
5998 receiver can decrypt the packet with several keys and check from
5999 the MAC which key decrypted the message correctly.
6001 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6002 lib/silccrypt/silccipher.[ch].
6004 * Added silc_hash_len to return the digest length into the
6005 lib/silcrypt/silchash.[ch].
6007 * Rewrote parts of Silc Channel Payload interface in the
6008 lib/silccore/silcchannel.[ch]. The encode function now also
6009 encrypts the packet and parse function decrypts it.
6011 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Fixed a minor formatting bug in the SKE's key material processing.
6014 It actually might have processed the keys wrong way resulting
6017 * Redefined the mandatory HMAC algorithms and added new algorithms.
6018 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6019 and hmac-md5 truncated to 96 bits. The mandatory is now
6020 hmac-sha1-96. Rest are optional (including the one that used
6021 to be mandatory). Rationale for this is that the truncated HMAC
6022 length is sufficient from security point of view and can actually
6023 make the attack against the HMAC harder. Also, the truncated
6024 HMAC causes less overhead to the packets. See the RFC2104 for
6027 * Added new [hmac] configuration section. The SKE used to use
6028 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6029 is of course wrong. The official names that must be proposed in
6030 the SKE are the ones defined in the protocol specification
6031 (hmac-sha1-96 for example). The user can configure any hmac
6032 using any hash function configured in the [hash] section. At
6033 least, the mandatory must be configured.
6035 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6037 * Added HMAC list to the SKE proposal list. It has now both
6038 hash algorithm list and HMAC list. This makes the protocol
6039 incompatible with previous versions. The SKE now seems to work
6040 the way it is supposed to work, for the first time actually.
6042 * Defined plain Hash algorithms to the protocol specification.
6045 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Implemented support for key agreement packets into the server.
6048 Added functions silc_server_key_agreement and
6049 silc_server_send_key_agreement. Other than these functions,
6050 server has nothing to do with this packet.
6052 * Added support for private message key packets into the server.
6053 Added functions silc_server_private_message_key and
6054 silc_server_send_private_message_key.
6058 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6059 called in the protocol's final callback instead in the END
6060 protocol state. This makes a little more sense and in the same
6061 time in client we can use the same protocol routines for normal
6062 key exchange and to key agreement packet handling as well.
6064 * Added to both client's and server's KE protocol context the
6065 SilcSKEKeyMaterial pointer to save the key material. We will
6066 bring the key material to the protocol's final callback by doing
6067 this. The final callback must free the key material.
6069 * Added SKE's packet_send callback into client's KE protocol
6070 context so that the caller can choose what packet sending function
6071 is used. This way we can use different packet sending when
6072 doing normal SKE when doing key agreement packet handling (in
6073 the key agreement packet handling we do not want to encrypt
6076 * Implemented the responder side of the key agreement routines
6077 in the client. The client can now bind to specified port and
6078 accept incoming key negotiation. The key material is passed
6079 to the application after the protocol is over.
6081 * Implemented the processing of incoming Key Agreement packet
6082 in the client. Added function silc_client_key_agreement to
6085 * Implemented the intiator side of the key agreement routines
6086 in the client. The client can now initiate key agreement with
6087 another remote client. The key material is passed to the
6088 application after the protocol is over.
6090 * Created client_keyagr.c to include all the key agreement
6093 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6094 SILC_TASK_CALLBACK except that it is not static.
6096 * Created client_notify.c and moved the Notify packet handling
6097 from the client.[ch] into that file.
6099 * Created client_prvmsg.c and moved all private message and
6100 private message key routines from the client.[ch] into that file.
6102 * Create client_channel.c and moved all channel message and
6103 channel private key routines from the client.[ch] into that file.
6105 * Changed silc_client_get_client_by_id_resolve to resolve with
6106 WHOIS command instead of IDENTIFY command, in the file
6107 lib/silclient/idlist.c.
6109 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Implemented the SKE's responder side to the Client library.
6113 * When FAILURE is received to the protocol do not trust it
6114 blindly. Register a timeout to wait whether the remote closes
6115 the connection as it should do it, only after that process the
6116 actual failure. This was changed to both client and server.
6118 * Added client_internal.h to include some of the structures
6119 there instead of client.h in lib/silcclient/.
6121 * Added function silc_task_unregister_by_callback to unregister
6122 timeouts by the callback function.
6124 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Some "Incomplete WHOIS info" errors has been appearing on the
6127 log files. Took away the entry->userinfo check from WHOIS
6128 reply sending. The entry->userinfo is now " " if client did not
6129 provide one. I thought this was fixed earlier but something
6130 is wrong still. Let's see if the error still appears.
6132 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Fixed a minor bug in the login when the channel key is
6135 re-generated in the server. It used to generate the key in
6136 wrong order and thus caused problems in the channel traffic.
6138 * Fixed a minor bug in channel key distsribution after
6139 KICK command. The key was not sent to the router even though
6142 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Added silc_ske_process_key_material_data as generic routine
6145 to process any key material as the SILC protocol dictates. The
6146 function is used by the actual SKE library but can be used by
6147 applications as well. This relates to the private message keys
6148 and the channel private keys since they must be processed the
6149 same way the normal SILC session keys. The protocol dictates
6150 this. Affected files: lib/silcske/silcske.[ch].
6152 Added also silc_ske_free_key_material to free the
6153 SilcSKEKeyMaterial structure.
6155 * Defined silc_cipher_set_key function to set the key for
6156 cipher without using the object's method function. The affected
6157 files: lib/silccrypt/silccipher.[ch].
6159 * Implemented silc silc_client_add_private_message_key,
6160 silc_client_add_private_message_key_ske,
6161 silc_client_del_private_message_key,
6162 silc_client_list_private_message_keys and
6163 silc_client_free_private_message_keys functions in the
6166 Added functions silc_client_send_private_message_key to send
6167 the Private Message Key payload and silc_client_private_message_key
6168 to handle incoming Private Message Key payload.
6170 * Added Cipher field to the Private Message Key payload to set
6171 the cipher to be used. If ignored, the default cipher defined
6172 in the SILC protocol (aes-256-cbc) is used.
6174 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Removed lib/silcclient/ops.h file.
6178 Redefined parts of the SILC Client Library API. Created new
6179 file silcapi.h that deprecates the ops.h file and defines the
6180 published Client Library API. Defined also private message key
6181 API and channel private key API into the file.
6183 This is the file that the application must include from the
6184 SILC Client Library. Other files need not be included by
6185 the application anymore.
6187 * Added new key_agreement client operation callback and also
6188 defined the Key Agreement library API for the application.
6190 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6193 is used by clients to request key negotiation between another
6194 client in the SILC network. If the negotiation is started it
6195 is performed using the SKE protocol. The result of the
6196 negotiation, the secret key material, can be used for example
6197 as private message key.
6199 Implemented the Key Agreement payload into the files
6200 lib/silccore/silauth.[ch].
6202 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Redefined ciphers for the SILC protocol. Added some new ciphers
6205 and defined the key lengths for the algorithms. Changed the
6206 code accordingly. The default key length is now 256 bits.
6208 * Fixed SKE key distribution function silc_ske_process_key_material
6209 when the key length is more than 128 bits. The default key
6210 length in SILC is now 256 bits.
6212 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6213 to indicate unsupported algorithm.
6215 * Renamed rijndael.c to aes.c and all functions as well.
6217 * Fixed a long standing channel key setting bug in client library.
6218 Weird that it has never surfaced before.
6220 * Fixed bug in channel deletion. If the entire channel is removed
6221 then it must also delete the references of the channel entry
6222 from the client's channel list as the client's channel entry and
6223 the channel's client entry share same memory.
6225 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Implemented CONNECT and SHUTDOWN commands in the client.
6229 * Implemented CLOSE command to the client.
6231 * Added the function silc_idlist_find_server_by_name into the
6232 files silcd/idlist.[ch].
6234 Added the function silc_idlist_find_server_by_conn into the
6235 files silcd/idlist.[ch].
6237 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * DIE command was renamed to SHUTDOWN. Updated the both code
6242 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6243 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6245 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6248 * Added function silc_server_create_connection function to create
6249 connection to remote router. My server implementation actually
6250 does not allow router to connect to normal server (it expects
6251 that normal server always initiates the connection to the router)
6252 so the CONNECT command is only good for connecting to another
6255 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6258 or some other client was kicked from the channel.
6260 Implemented the handling of the notify type to both client
6263 Implemented silc_server_send_notify_kicked to send the KICKED
6264 notify. It is used to send it to the server's primary router.
6266 * Implemented the KICK command into server and client.
6268 * Added `query' argument to the silc_idlist_get_client function
6269 to indicate whether to query the client from server or not if
6272 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6273 to indicate that the client is not channel founder.
6277 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * Removed the rng context from SilcPacketContext structure and
6280 changed that the packet routine uses the Global RNG API.
6282 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Added support for quit message that client can "leave" on the
6285 channel when it quits the SILC. It is ditributed inside the
6286 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6288 Added silc_server_free_client_data that will take the
6289 signoff message as argument.
6291 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6293 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6295 * Updated parts of the protocol specification to keep it up
6298 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6301 payloads in one packet.
6303 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6304 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6305 use now the new List flag.
6307 * Also deprecated the following packet types: REPLACE_ID,
6308 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6310 * Added list support for Notify packet in server.
6312 * Added silc_server_send_notify_channel_change to send the
6313 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6314 the silc_server_send_replace_id.
6316 * Added silc_server_send_notify_nick_change to send the
6317 NICK_CHANGE notify type. Deprecates the function
6318 silc_server_send_replace_id.
6320 * Added silc_server_send_notify_join to send the JOIN notify type.
6321 Deprecates the function silc_server_send_new_channel_user.
6323 * Added silc_server_send_notify_leave to send LEAVE notify type.
6324 Deprecates the function silc_server_send_remove_channel_user.
6326 * Added silc_server_send_notify_cmode and
6327 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6328 types. Deprecates the silc_server_send_set_mode function.
6330 * Added SERVER_SIGNOFF notify type to indicate that server has
6331 quit. This means that all clients on the channel from that
6332 server will drop. This can be also used when netsplit happens.
6334 Deprecated REMOVE_ID packet type since it is not needed anymore
6337 Added silc_server_send_notify_server_signoff to send the
6338 SERVER_SIGNOFF notify type. Deprecates the function
6339 silc_server_send_remove_id.
6341 Added also silc_server_send_notify_signoff to send the
6342 SIGNOFF notify type.
6344 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6345 SILC protocol from this day on. Changed the protocol
6346 specification as well.
6348 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6349 notify type. It is used between routers to notify about
6350 topic changes on a channel.
6352 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6355 * Partly updated the protocol specification to comply with the
6356 changes now made. It is still though a bit outdated.
6358 * The JOIN notify type now takes one extra argument <Channel ID>.
6359 The packet used to be destined to the channel but now the
6360 JOIN type may be sent as list thus it is impossible to
6361 destine it to any specific channel. By adding this argument
6362 it is again possible.
6364 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Added CREDITS file. The CHANGES and CREDITS file will appear
6367 in the distribution as well.
6369 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6372 types in the server's silcd/packet_receive.c.
6374 * Implemented CMODE and CUMODE to work in router environment.
6376 * Fixed minor encoding and decoding buglet from the
6377 lib/silccore/silcmode.c.
6379 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6382 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6384 * Changed all SilcConfigServer* and silc_config_server* to
6385 SilcServerConfig* and silc_server_config*, respectively.
6388 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Associated the ID (client or server ID) to the Authentication
6391 Payload to avoid any possibility of forging. Updated the
6392 protocol specification and the code accordingly.
6394 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * The RSA key length is now save to the RsaKey context in the
6397 key generation process in lib/silccrypt/rsa.c. The key length
6398 is now used to figure out the maximum size of the block allowed
6399 to be encrypted/signed.
6401 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6402 is equivalent to the silc_mp_mp2bin but does not allocate any
6405 * Changed silc_mp_mp2bin API to take length argument. If it is
6406 non-zero then the buffer is allocated that large. If zero, then
6407 the size is approximated using silc_mp_sizeinbase, which however
6410 * Created Global RNG API which is global RNG that application can
6411 initialize. After initializing, any routine anywhere in the
6412 code (including library) can use RNG without allocating a new
6413 RNG object. This was done to allow this sort of use of the
6414 RNG in code that has no chance to allocate RNG object. All
6415 applications currently allocate this and many routines in the
6416 library use this. Affected file lib/silccrypt/silcrng.[ch].
6418 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6419 it to use the Global RNG API.
6421 * Defined Authentication Payload into protocol specification that
6422 is used during SILC session to authenticate entities. It is
6423 used for example by client to authenticate itself to the server
6424 to obtain server operator privileges.
6426 Implemented this payload into the lib/silccore/silcauth.[ch].
6427 Implemented also routines for public key based authentication
6428 as the new protocol specification dictates.
6430 Moved definitions of different authentication methods from
6431 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6433 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6434 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6435 silc_pkcs_verify_with_hash functions into the file
6436 lib/silccrypt/silcpkcs.[ch].
6438 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * The client entry's userinfo pointer must be always valid.
6441 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6442 will fail since it requires the userinfo. Now, the userinfo
6443 is allocated as "" if actual userinfo does not exist. Actually,
6444 it must exist and it is totally Ok to drop client connections
6445 that does not announce the userinfo. However, we will make
6446 this workaround for now.
6448 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6449 to return the remote port by socket.
6451 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6454 SILC_SERVER_PENDING_EXEC and added an new macro
6455 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6456 data or when error occurs while processing the pending command.
6458 Added new argument `destructor' into silc_server_command_pending
6459 and to the SilcServerCommandPending object. This destructor is
6460 now called after calling the pending callback or if error occurs
6461 immediately. If error occurs the actual pending callback won't
6462 be called at all - only the destructor. The destructor may be
6463 NULL if destructor is not needed.
6465 All this applies for client library code as well. Similar
6466 changes were made there as well for the pending commands.
6468 In the client, the application must now allocate the
6469 SilcClientCommandContext with the silc_client_command_alloc
6472 * Added reference counter to the SilcServerCommandContext. Added
6473 function silc_server_command_alloc and silc_server_command_dup
6476 Same type of functions added to the client library for the same
6479 * Removed the cmd_ident from IDListData away since it is now
6480 global for all connections. It is the command identifier used
6481 in command sending and with pending commands. The affected file
6484 * Added reference counter to the SilcSocketConnection objecet to
6485 indicate the usage count of the object. The object won't be
6486 freed untill the reference counter hits zero. Currently only
6487 server uses this, and client ignores it. The client must be
6488 set to use this too later. The affected files are
6489 lib/silccore/silcsockconn.[ch]. Added also the function
6490 silc_socket_dup to increase the reference counter.
6492 This was mainly added because it is possible that the socket
6493 is removed underneath of pending command or other async
6494 operation. Now it won't be free'd and proper DISCONNECTING
6495 flags, etc. can be set to avoid sending data to connection that
6496 is not valid anymore.
6498 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6499 the connection. After that it sets SILC_SET_DISCONNECTED.
6500 It is, however, possible that the socket data is not still freed.
6501 The silc_server_packet_process now checks that data is not
6502 read or written to connection that is DISCONNECTED. The socket
6503 get's freed when the reference counter hits zero.
6505 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Changed the client operation API: channel_message operation's
6508 `sender' is now the client entry of the sender, not the nickname
6509 and the `channel' is the channel entry, not the channel name.
6511 In the private_message operation the `sender' is now also the
6512 client entry of the sender not the nickname.
6514 Affected file is lib/silcclient/ops.h and all applications
6515 using the client operations.
6517 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Moved the calling of ops->connect() from connect_to_server_final
6520 into receive_new_id functin since that is the point when the
6521 client is actually allowed to send traffic to network. The
6522 affected file is lib/silcclient/client.c.
6524 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6527 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6528 (if needs broadcasting) instead of broadcasting the packets one
6529 by one which would make a burst in the network traffic.
6531 * Added `broadcast' argument to the functions in silcd/server.[ch]
6532 silc_server_create_new_channel[_with_id] to indicate whether
6533 to send New Channel packet to primary router.
6535 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Added new function into the silcd/server.[ch] files:
6538 silc_server_create_new_channel_with_id to create new channel with
6539 already existing Channel ID.
6541 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6542 lib/silccore/silcpacket.h. This packet is used t send list of
6543 Set Mode payloads inside one packet. Server uses this to set
6544 the modes for the channels and clients on those channels, that it
6545 announced to the router when it connected to it. The protocol
6546 specification has been updated accordingly.
6548 * The silc_server_new_channel did not handle the packet coming
6549 from normal server as it normally does not send that. However,
6550 when it announces its channels it does send it. Implemented
6551 the support for that.
6553 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6554 into the file lib/silccore/id.h.
6556 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Fixed memory leaks in the functions silc_idlist_del_client,
6559 silc_idlist_del_channel and silc_idlist_del_server in the file
6560 silcd/idlist.c. All of those leaked like a sieve.
6562 * Fixed some small memory leaks in the client's function
6563 silc_client_notify_by_server.
6565 * Added functions into silcd/server.c: silc_server_announce_clients,
6566 silc_server_announce_channels and silc_server_announce_server.
6567 These functions are used by normal and router server to announce
6568 to its primary router about clients, channels and servers (when
6569 router) that we own. This is done after we've connected to the
6572 These functions effectively implements the following packet types:
6573 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6574 and SILC_PACKET_NEW_ID_LIST.
6576 * Added new functions into the silcd/packet_receive.[ch]:
6577 silc_server_new_id_list, silc_server_new_channel_list and
6578 silc_server_new_channel_user_list to handle the incoming
6579 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6581 * Added support of changing Channel ID in the function
6582 silc_server_replace_id. If the server that announces a channel
6583 to the router already exists in the router (with same name but
6584 with different Channel ID), router is responsible to send
6585 Replace ID packet to the server and force the server to change
6586 the Channel ID to the one router has.
6588 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6589 client that the Channel ID has been changed by the router. The
6590 normal server sends this to the client. Client must start using
6591 the new Channel ID as the channel's ID.
6593 Implemented handling of this new type into lib/silcclient/client.c
6594 into the function silc_client_notify_by_server.
6596 * Added new function silc_idlist_replace_channel_id into the files
6597 silcd/idlist.[ch] to replace the Channel ID.
6599 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Call silc_server_command_identify_check always when processing
6602 the IDENTIFY command in silcd/command.c
6604 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6607 send keepalive packets. The packet can be sent by clients,
6608 servers and routers.
6610 Added function silc_socket_set_heartbeat into the file
6611 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6612 If not set, the heartbeat is not performed. The actual
6613 heartbeat is implemented in the low level socket connection
6614 library. However, application is responsible of actually
6617 Added silc_server_send_heartbeat to send the actual heartbeat
6618 packet into silcd/packet_send.[ch]. Server now performs
6619 keepalive with all connections.
6621 * Added silc_task_get_first function into lib/silcutil/silctask.c
6622 to return the timeout task with shortest timeout. There was a bug
6623 in task unregistration that caused problems. TODO has been
6624 updated to include that task system must be rewritten.
6626 * The client library will now resolve the client information when
6627 receiving JOIN notify from server for client that we know but
6628 have incomplete information.
6630 * Rewrote parts of silc_server_remove_from_channels and
6631 silc_server_remove_from_one_channel as they did not remove the
6632 channel in some circumstances even though they should've.
6634 * Encryption problem encountered in server:
6636 The LEAVE command used to send the Channel Key packet to the
6637 router immediately after generating it. However, the code
6638 had earlier sent Remove Channel user packet but not immediately,
6639 ie. it was put to queue. The order of packets in the router
6640 was that Channel Key packet was first and Remove Channel User
6641 packet was second, even though they were encrypted in the
6642 reverse order. For this reason, MAC check failed. Now, this
6643 is fixed by not sending the Channel Key packet immediately but
6644 putting it to queue. However, this is more fundamental problem:
6645 packets that are in queue should actually not be encrypted
6646 because packets that are sent immediately gets encrypted
6647 actually with wrong IV (and thus MAC check fails). So, packets
6648 that are in queue should be encrypted when they are sent to
6649 the wire and not when they put to the queue.
6651 However, the problem is that the current system has not been
6652 designed to work that way. Instead, the packet is encrypted
6653 as soon as possible and left to the queue. The queue is then
6654 just purged into wire. There won't be any fixes for this
6655 any time soon. So, the current semantic for packet sending
6658 o If you send packet to remote host and do not force the send
6659 (the packet will be in queue) then all subsequent packets to the
6660 same remote host must also be put to the queue. Only after the
6661 queue has been purged is it safe again to force the packet
6664 o If you send all packets immediately then it safe to send
6665 any of subsequent packets through the queue, however, after
6666 the first packet is put to queue then any subsequent packets
6667 must also be put to the queue.
6669 Follow these rules and everything works fine.
6671 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Added new function silc_server_remove_clients_by_server to
6674 remove all client entries from ID list when the server connection
6675 is lost. In this case it is also important to invalidate all
6676 client entires as they hold the invalid server entry. This
6677 fixes fatal bug when server has lost connection and will reconnect
6680 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6682 * Made some sanity checks to silc_server_daemonise like to check
6683 whether the requested user and group actually exists.
6685 * Added sanity check to SKE's silc_ske_responder_finish to check
6686 that the public and private key actually is valid.
6688 * Invalidate the client's nickname when receiving Replace ID
6689 packet and the Client ID is being replaced. This means that the
6690 server will query the nickname if someone needs it (client)
6693 * Sort the ID Cache in client library when the ID Cache data
6694 has changed (needs sorting).
6696 * Do not allow for SILC client to create several connections to
6697 several servers. The client does not support windows right now
6698 and generating multiple connections causes weird behaviour.
6700 Irssi-silc client does support windows and can handle several
6701 connections without problems, see: www.irssi.org and SILC plugin.
6703 * Fixed some places where client was added to the IDList. The
6704 rule of thumb is following (in order to get everything right):
6705 If the client is directly connected local client then the
6706 `connection' argument must be set and `router' argument must be
6707 NULL to silc_idlist_add_client function. If the client is not
6708 directly connected client then the `router' argument must
6709 bet set and the `connection' argument must be NULL to the
6710 silc_idlist_add_client function.
6712 * The funtion silc_server_packet_send_local_channel actually did
6713 not check whether the client was locally connected or not. It
6714 does that now. Fixed a bug related to LEAVE command.
6716 * Fixed Remove Channel User payload parsing bug in server's
6717 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6719 * The server's silc_server_save_channel_key now checks also the
6720 global ID list for the channel as it might not be in the local
6721 list. Fixed a bug related to LEAVE command.
6723 * Is this the end of the [<unknown>] buglet that has been lurking
6724 around for a long time? A little for loop fix in server's
6725 silc_server_command_whois_parse that is used by both IDENTIFY
6726 and WHOIS command. At least, this was a clear bug and a cause
6727 of one type of [<unknown>] buglet.
6729 * WHOIS and IDENTIFY commands call the function
6730 silc_server_command_[whois/identify]_check function even if
6731 we are not router server.
6733 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Added --with-gmp configuration option. If set the GMP
6736 is always compiled in the SILC source tree. If not set then
6737 it is checked whether the system has the GMP3 installed. If
6738 it has then the GMP won't be compiled (the system's headers
6739 and library is used), if it doesn't have it then the GMP is
6740 compiled in the SILC source tree.
6742 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Changed RSA private exponent generation to what PKCS #1
6745 suggests. We try to find the smallest possible d by doing
6746 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6747 not security fix but optimization.
6749 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6751 * Added new config entry [Identity] to fork the server and run
6752 it as specific user and group. A patch from Bostik.
6754 * Imported Dotconf configuration library into lib/dotconf.
6755 This will be used to create the SILC configuration files later.
6756 It will appear in the distsribution after this commit.
6758 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * A big code auditing weekend happening. Auditing code for
6761 obvious mistakes, bugs and errors. Also, removing any code
6764 Removed files for being obsolete:
6766 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6767 inline in the file lib/silcutil/silcbuffer.h)
6769 o lib/silcutil/silcbufutil.c (the header has inline versions)
6771 Changed code to fix possible error conditions:
6773 o The buffer formatting routines now check that the destination
6774 buffer really has enough space to add the data. This applies for
6775 both buffer formatting and unformatting
6776 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6777 unformatting was changed to accomodate following rules:
6778 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6779 sent to the function while XXX_*STRING will not allocate or copy
6780 the data into the buffer. Instead it sets the pointer from the
6781 buffer into the pointer sent as argument (XXX_*STRING used to
6782 require that the pointer must be allocated already). This change
6783 makes this whole thing a bit more consistent and more optimized
6784 (note that the data returned in the unformatting with XXX_*STRING
6785 must not be freed now). The routines return now -1 on error.
6787 o Tried to find all code that use buffer_format and buffer_unformat
6788 and added return value checking to prevent formatting and
6789 especially unformatting errors and possible subsequent fatal
6792 o Changed ske->x and ske->KEY to mallocated pointers in
6793 lib/silcske/silcske.h. Fixed possible data and memory leak.
6795 o Added return value checking to all *_parse* functions. Fixed
6796 many memory leaks as well.
6798 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6799 so that buffer overflows would not happen. All code now also
6800 checks the return value as it can fail.
6802 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Added reconnection support to server if the normal server looses
6805 its connection to the router (for example if router is rebooted).
6806 The server performs normal reconnection strategy implemented
6807 to the server. Affected file silcd/server.c.
6809 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6811 * Added new packet type SILC_PACKET_SET_MODE that is used to
6812 distribute the information about changed modes (for clients,
6813 channels and clients channel modes) to all routers in the
6814 network. Updated the protocol specification accordingly.
6816 Added functions into silcd/packet_send.c and
6817 silcd/packet_receive.c: silc_server_send_set_mode,
6818 silc_server_set_mode.
6820 Added new files silcmode.[ch] into lib/silccore that implements
6821 the encoding and decoding of Set Mode Payload. Added new type
6822 SilcSetModePayload. Moved the definitions of different modes
6823 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6825 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Oops, a little mistake in server's connection authentication
6828 protocol. The protocol is not ended with FAILURE but with
6829 SUCCESS if the authentication is Ok. :) Affected file is
6832 * Implemented NICK_CHANGE notify handling in server in the file
6833 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6834 the local clients on the channel. After the changing nickname
6835 in router environment snhould work and the [<unknown>] nickname
6836 should appear no more.
6838 The silc_server_replace_id function that receives the Replace ID
6839 payload now sends the NICK_CHANGE notify type also in the file
6840 silcd/packet_receive.c
6842 * Changed WHOIS and IDENTIFY command to support the maximum amount
6843 of arguments defined in protocol specs (3328 arguments). This
6844 fixed a bug that caused problems when there were more than three
6847 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Added extra parameter, command identifier, to the
6850 silc_client_send_command so that explicit command identifier
6853 Changed that ID list routines uses specific command identifier
6854 when sending WHOIS/IDENTIFY requests to the server so that they
6855 can be identified when the reply comes back.
6857 Affected files lib/silcclient/command.[ch],
6858 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6860 * Added `sender' argument to silc_server_packet_send_to_channel
6861 to indicaet the sender who originally sent the packet to us
6862 that we are now re-sending. Ignored if NULL. Affected file
6863 silcd/packet_send.[ch].
6865 * Added some server statistics support in silcd/server_internal.h
6866 SilcServerStatistics structure and around the server code. Also
6867 send some nice statistics information when client is connecting
6870 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Fixed channel ID decoding in server's JOIN command reply in
6873 silcd/command_reply.c
6875 * Fixed braodcasting of replace ID payload to not to send it if
6876 we are standalone server in silcd/packet_receive.c.
6878 * Fixed all channel message sending routines to not to send
6879 packets to clients that has router set, since they are routed
6880 separately in the same function earlier. Affects file
6881 silcd/packet_send.c and all channel packet sending functions.
6883 * In USERS reply, res_argv[i] are not allocated, the table
6884 is allocated. Thus changed that free the table, not its
6887 * In server's whois_check and identify_check if the client is
6888 locally connected do not send any WHOIS commands - they are not
6891 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6893 * Fixed some minor bugs in client when sending WHOIS command. The
6894 arguments was in wrong order.
6896 * Removed statis function add_to_channel from server in
6897 silcd/command.c that was previously used with the joining but
6900 * Tested USERS command in router environment successfully with two
6901 routers, two servers and two clients.
6903 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6905 * Reorganized the USERS command and command reply in client library
6906 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6907 When the command is given by user we register a pending command
6908 callback that will reprocess the command after the reply has been
6909 received from the server. When reprocessing the packet we then
6910 display the information. Thus, the USERS information is displayed
6911 now in the command callback instead of in the command reply
6912 callback. The processing of the command is same as previously
6913 when server has sent the command reply in the JOINing process.
6915 * Added to USERS command in silcd/command_reply.c to join the client,
6916 we didn't use to know about, to the channel after we've created
6917 a client entry for it. Also, for clienet we did know already still
6918 check whether it is on the channel or not and add it if not.
6920 * Removed silc_server_command_join_notify as the function and its
6923 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Changed the client's pending command handling to the same as the
6926 server's pending command handling. It is also now possible to
6927 execute command reply functions from other command reply
6928 function as the function callbacks for commands and command
6929 replies are one and same. The pending commands are not static
6930 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6931 in client connection context. Thus, pending commands are server
6932 connection specific as it is convenient.
6934 Changed the function silc_client_command_pending and
6935 silc_client_command_pending_del and added new function
6936 silc_client_command_pending_check. Removed the
6937 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6940 * Added cmd_ident, current command identifier, to the client
6941 connection context in lib/silcclient/client.h to keep track on
6942 command identifiers used in command sending. Client's command reply
6943 function handling now supports the mandatory command identifiers.
6945 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6946 funtions in client to fully support pending command callbacks.
6948 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6949 as one of the arguments to the application in the command reply
6952 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6953 before first releasing SILC but came back. Now it is removed again
6954 and should come back nomore. The FORWARDED flag was used only
6955 by the JOINing procedure by forwarding the command packet to router.
6956 Now, the JOINing procedure has been changed to more generic (due
6957 to various router environment issues) and FORWARDED is not needed
6958 anymore for anything. The protocol specification is yet to be
6961 Now, removed silc_server_packet_forward from server and the flag
6962 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6964 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Renamed NAMES command to USERS command. The NAMES was named that
6967 due to historical reasons. Now it is renamed. Also, rewrote
6968 parts of the USERS command. The nickname list is not sent anymore
6969 by the server. Only Client ID and mode lists are sent in the USERS
6970 command. Changed this also to the protocol specification.
6972 The client now resolves the names and stuff after it receives
6973 the USERS list from the server when joining to the channel.
6975 * WHOIS and IDENTIFY commands has been changed to support multiple
6976 Client ID's per command. One can now search for multiple users
6977 in the network by sending only one WHOIS or IDENTIFY command.
6978 Changed the code and the protocol specifications.
6980 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6981 uses silc_server_command_whois_parse to parse the request. */
6983 * If normal server, do not parse the WHOIS and IDENTIFY requests
6984 before sending it to the router. Saves some time.
6986 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Fixed JOIN command on client library. Wrong number of arguments
6989 used to crash the client.
6991 * Added silc_server_channel_has_global function to check whether
6992 channel has global users or not.
6994 * Added silc_server_channel_has_local function to check whether channel
6995 has locally connected clients on the channel.
6997 * The silc_server_remove_from_one_channel now checks whether the
6998 channel has global users or not after given client was removed from
6999 the channel. It also checks whether the channel has local clients
7000 on the channel anymore. If it does not have then the channel entry
7001 is removed as it is not needed anymore.
7003 * The silc_server_notify now checks on JOIN notify whether the joining
7004 client is one of locally connected or global. If it is global then
7005 the channel has now global users on the channel and that is marked
7006 to the channel entry. Also, it now saves the global client to
7007 global list who is joining and JOINs it to the channel. This is
7008 for normal server, that is.
7010 Changed silc_server_send_notify_on_channel,
7011 silc_server_packet_relay_to_channel and
7012 silc_server_packet_send_to_channel check if we are normal server
7013 and client has router set (ie. global client) do not send the
7014 message to that client, as it is already routed to our router.
7016 * Implemented LEAVE notify type handling in silc_server_notify
7019 * Tested LEAVE command in router environment successfully. Tested
7020 with two routers, two servers and two clients.
7024 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7026 * Implemented SIGNOFF notify type handling in silc_server_notify
7029 * silc_server_remove_id now removes the client entry from all channels
7030 it has joined and thusly sends SIGNOFF notify type.
7032 * Rewrote the NAMES list generation in server by removing two excess
7033 loops. The lists are created now inside one loop.
7035 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * silc_server_remove_channel_user checks now also global list
7038 for channel and client.
7040 * silc_server_new_channel_user checks now both local and global
7041 list for channel and client. Fixed a bug in client id decoding.
7042 Used to decode wrong buffer.
7044 * silc_server_channel_message checks now both local and global
7045 list for channel entry.
7047 * Tested channel joining (hence JOIN) in router environment
7048 successfully. Tested with two routers, two servers and two
7051 * Tested channel message sending in router environment successfully.
7053 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Added silc_server_save_channel_key into server.[ch] to save the
7056 received channel key in Channel Key payload processing. It is
7057 also used in JOIN command reply handling.
7059 Equivalent function silc_client_save_channel_key added into
7060 client.[ch] into client library.
7062 * Changed JOIN command reply to send information whether the channel
7063 was created or not (is existing already) and the channel key
7064 payload. Changed protocol specs accordingly.
7066 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7067 the request was sent by ID and not by nickname. Crashed on
7070 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7073 now correctly save the received data.
7075 * silc_server_free_sock_user_data now notifies routers in the
7076 network about entities leaving the network.
7078 At the same time implemented functions silc_server_remove_id
7079 and silc_server_send_remove_id to receive and send REMOVE_ID
7080 packets. The packet is used to notify routers in the network
7081 about leaving entities. The ID removed will become invalid in
7084 * Added function silc_idlist_del_server into server. Removes and
7085 free's server entry from ID list.
7087 * silc_server_private_message function now checks, if we are router,
7088 that the destination ID really is valid ID, naturally.
7090 * In router when NEW_ID packet is received (for new client) the
7091 hash of the Client ID is saved in the ID Cache but the
7092 client->nickname is set to NULL, instead of putting the hash
7095 IDENTIFY command now also checks that client->nickname must be
7096 valid. If it is not if will request the data from the server who
7097 owns the client. Added new function
7098 silc_server_command_identify_check.
7100 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7101 to set the command to already allocated Command Payload.
7103 * Tested private message sending in router environment with two
7104 routers, two servers and two clients. Fixed minor bugs and now
7107 * Fixed segfault from client's NAMES command. Used to crash if
7110 * Forwarded packets must not be routed even if it is not destined
7111 to the receiver. Changed server code comply with this.
7113 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Added `require_reverse_mapping' boolean value to ServerParams
7116 structure. If TRUE (not default) the server will require that
7117 the connecting host has fully qualified domain name.
7119 If the reverse mapping is not required and hostname could not be
7120 found the IP address is used as hostname.
7122 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Implemented version string checking to both client and server.
7125 The check is incomplete currently due to the abnormal version
7126 strings used in development version of SILC.
7128 * Changed all command functions in server to use the new
7131 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7133 * Changed char *data to unsigned char *data in ID Cache system to
7134 support binary data as ID Cache data. Changed code to support
7135 binary data in lib/silccore/idcache.c.
7137 * Renamed silc_server_packet_relay_command_reply to
7138 silc_server_command_reply as it is normal packet receiving
7139 function. Rewrote the function to accept command replys for
7140 servers and not only for clients.
7142 * Mark remote router always as registered server if we are connecting
7143 to it. Otherwise, commands sent by the router to us are ignored.
7145 * All ID List find routines now returns the ID Cache Entry pointer
7146 as well if requested.
7148 * WHOIS command works now in router environment, tested with two
7149 routers, two servers and two clients.
7151 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7152 in router environment (as it is almost equivalent to WHOIS) but
7153 hasn't been tested thoroughly. Added new functions:
7155 silc_server_command_identify_parse
7156 silc_server_command_identify_send_reply
7157 silc_server_command_identify_from_client
7158 silc_server_command_identify_from_server
7160 * Disabled route cache adding because adding two different ID's with
7161 same IP replaces the old cache entry thus giving wrong route.
7162 The entry->router->connection is always the fastest route anyway
7163 so route cache may not be needed. Of course, new routes maybe
7164 established after receiving the ID when the entry->router->connection
7165 might not be anymore the most optimal.
7167 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7169 * Add route cache for received ID for fast routing.
7171 * Added silc_server_packet_route to route received packet on router
7172 that is not destined to us.
7174 * Renamed silc_server_get_route to silc_server_route_get.
7176 * Added id_string and id_string_len fields into SilcServer to
7177 include encoded ServerID for fast comparing without excess
7178 encoding of the ID's.
7180 * Cleaned up WHOIS command on server side. Added following static
7183 silc_server_command_whois_parse
7184 silc_server_command_whois_check
7185 silc_server_command_whois_send_reply
7186 silc_server_command_whois_from_client
7187 silc_server_command_whois_from_server
7189 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7190 arguments in command replies. All command functions should be
7191 updated to use this macro.
7193 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Minor typo fixes on command reply handling on server.
7197 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Added silc_server_command_add_to_channel internal routine to add
7200 the client to the channel after router has created the channel and
7201 sent command reply to the server.
7203 * Added generic silc_server_send_command to send any command from
7206 * Use static buffer with ID rendering instead of duplicating data.
7208 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Fixed a channel user mode bug when joining to a channel server gave
7211 everybody channel founder rights, oops.
7213 * We mark ourselves as the router of the incoming server connection
7214 if we are router ourselves. This way we can check in some packet
7215 sending functions whether it is locally connected server. For
7216 incoming router connections we put NULL.
7218 * For router sending packets locally means now always sending the
7219 packet cell wide; to local clients and local servers. For normal
7220 server sending packet locally means sending it to only local
7223 * Fixed the JOIN command to really work in router environment. If the
7224 channel is created it is always created by the router. Router is
7225 also responsible of making the initial joining to the channel,
7226 sending JOIN notify to the sending server and distributing
7227 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7228 does not exist server doesn't do anything else but forward the
7229 command to the router which performs everything.
7231 * Added silc_server_send_channel_key function to send the Channel Key
7234 * Added silc_server_create_channel_key to create new channel key. The
7235 channel key is now re-generated everytime someone joins or leaves
7236 a channel, as protocol dictates. Note: channel->key_len is the
7239 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7241 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7242 packet_receive.[ch] to separate packet sending and receiving
7243 routines. The server.[ch] now includes everything else including
7244 actual packet processing (writing and reading data) and other
7247 Renamed silc_server_private_message_send_internal to
7248 silc_server_send_private_message. The routine is still though
7249 used only to relay private messages as server does not send
7250 private messages itself.
7252 Renamed silc_server_new_channel to silc_server_create_new_channel
7253 and added new function sicl_server_new_channel that handles the
7254 incoming New Channel packet. Added also new sending function
7255 silc_server_send_new_channel to send New Channel Payload.
7257 * Added new function silc_server_notify to process incoming notify
7258 packet to the server/router. Server may then relay the notify
7259 to clients if needed.
7261 * Added new function silc_server_new_channel_user to process incoming
7262 New Channel User packet. Router will redistribute the packet and
7263 send JOIN notify to its local clients and locally connected servers
7264 if needed. Normal server will send JOIN notify to its local client
7265 on same channel when received this packet. Added also corresponding
7266 sending function silc_server_send_new_channel_user to sent the
7269 * Added boolean route argument to send_notif_to_channel and
7270 packet_send_to_channel functions to attempt to route the packet
7271 if it is TRUE and send only locally if it is FALSE.
7273 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * silc_server_replace_id now broadcasts the received replace ID
7276 packet if it is not broadcast packet already. The router must
7277 broadcast to inform other routers about changed ID.
7279 * Added backpointer to server's router into SilcServer context in
7280 silcd/server_internal.h.
7282 * Fixed silc_server_packet_broadcast to send correct broadcast
7285 * The channel key is now distributed to the local client as soon
7286 as it is received from the router (in router environment) so that
7287 no other packet may be sent for the channel until client has
7290 * silc_server_remove_channel_user now broadcasts the received
7291 Remove Channel User packet if it is not broadcast packet already.
7292 The router must broadcast to inform other routers about removed
7295 * Added users field into SilcPacketContext that is a reference count
7296 of the context. One can increase the reference count by calling
7297 silc_packet_context_dup which is now changed to just increase the
7298 reference count instead of duplicating the data. The reference
7299 count is decresed by calling silc_packet_context_free that will
7300 free the data after the reference count hits zero.
7302 For now on the packet context and everything allocated into it
7303 (including the raw packet from network) must be freed by calling
7304 the new silc_packet_context_free function. Added also new function
7305 silc_packet_context_alloc that must be used now to allocate the
7306 context. This also means that if a routine is asynchronous from
7307 silc_[client/server]_packet_parse_type the packet context must
7308 be duplicated by calling silc_packet_context_dup. Otherwise it
7309 gets free'd after silc_[client/server]_packet_parse_type returns.
7310 Also, one must remember that if packet is duplicated then its
7311 reference count must be decresed by calling the free function as
7312 many times as it was duplicated.
7314 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7315 from both client and server.
7317 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Made joining to a channel working in router environment.
7321 * Cleaned up JOIN command on server side and create function
7322 silc_server_command_join_channel internal routine to make the
7325 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Changed silc_command_pending list to SilcDList. Also, added
7328 `ident' field to SilcServerCommandPending structure to identify
7329 the reply and to call correct callback.
7331 Added silc_server_command_pending_check function to replace the
7332 corresnponding macro. The silc_command_pending list is not
7335 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7336 to set identifier to previously allocated Command Payload. It
7337 is used to set identifier for command when resending Command
7340 * Added silc_command_payload_encode_payload to encode Command
7341 Payload buffer from SilcCommandPayload structure.
7343 * Added silc_argument_payload_encode_payload to encode Argument
7344 payload buffer from SilcArgumentPayload structure.
7346 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Changed WHOIS command to support router connection on server side.
7349 The whois request is always sent to router unless the server is
7350 standalone server. After server has received the reply from the
7351 router will it send the reply to the client.
7353 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7354 broadcast received broadcast packet. The function is used only
7355 by router. The broadcast packet is always sent to the router's
7358 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7359 render given ID to printable string, for log files for example.
7361 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7363 * Made basic router to router connections working. At least they
7364 can now connect to each other but nothing really works the way
7365 they are supposed - yet.
7367 * Added new initiator token to RouterConnection configuration
7368 file in silcd/serverconfig.[ch]. It is used to tell whether we
7369 are the initiator to the remote router or whether we'll expect
7370 the other end to connect.
7372 * Moved registering of listener task to silc_server_init, hence
7373 the server starts listenning as soon as it is run, even if it
7374 does not have connections to other routers. Let's see how well
7377 * Changed default connection retry timeouts for more suitable in
7380 * Removed cipher and such arguments from silc_idlist_add_client
7381 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7382 Added new function silc_idlist_add_data to add the keys and stuff
7385 * Added SilcIDListData structure and added it to SilcClientEntry
7386 and SilcServerEntry as their first field in the structure. This
7387 way we can explicitly cast the ID entries to the SilcIDListData
7388 structure and get common data for the entries. In past, we had
7389 to first check what type of connection it is and then cast it to
7390 correct ID entry type. Now, we can directly cast the opaque
7391 pointer to the SilcIDListData (no matter what ID entry it actually
7392 is) and get the data needed.
7394 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7396 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7397 in some circumstances even if threre were timeout tasks, though not
7398 IO tasks, but tasks anyway. Now fixed.
7400 * Defined SilcServerConnection structure to hold connection specific
7401 stuff about directly connected servers and routers. The definition
7402 is currently in silcd/server_internal.h. I thought about having
7403 a bit more important role fro this struct but for now it is used
7404 only when connecting to other server (or router actually).
7406 * Added connecting retry support in server when connecting to
7407 router(s). The retry feature implement exponential backoff
7408 algorithm. Also, added SilcServerParams structure to hold default
7409 parameters for server. For now, it include these retry settings
7410 and are hard coded. After server is moded to be as Silc Server
7411 Library this structure will be more important.
7413 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7415 * Changed client librarys channel->clients table to SilcList and
7416 changed code accordingly.
7418 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * Changed client's channel table to SilcList and changed code
7421 accordingly. Also changed SilcChannelClientEntry to include back-
7422 pointer to the channel so that client entry can use that structure
7423 as list as well and we have fast cross-reference to the channel.
7424 This change dramatically decreased the complexity of channel
7425 handling with client entry and vice versa (removed one extra
7426 loop when searching for channel entry from many functions).
7428 * Changed server->sim from table to SilcDList and changed code
7431 * NAMES command can now be used from user interface. It will show
7432 the user list on the channel, neatly.
7434 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7435 Code now saves realname of the user if it becomes available.
7437 * Renamed configure.in to configure.in.pre and made ./prepare
7438 script to automatically add correct version string to
7439 configure.in which it creates from configure.in.pre.
7441 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * NAMES command reply now shows users mode with the nickname when
7446 * Moved silc_client_ch[u]mode[_char] functions from
7447 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7448 place sucks, they are utility functions and should be in some
7451 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7453 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7456 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Added TRQ (efficient deque and list library) into lib/trq. This is
7461 a very good list library that is currently used in the SILC. Defined
7462 SilcList API over the library because I didn't like the API very
7463 much. See lib/trq/silclist.h for the API and examples of how to
7464 use the API. Fixed various places in the code to use the new
7465 SilcList API. The SilcList is meant for lists that has a structure
7466 already defined as a list. It is not suitable to add just some
7467 context to the list (in TRQ, the context is the list actually).
7469 So, I defined SilcDList that can be used for the purpose where
7470 predefined list structure does not exit. This can be used as
7471 such list. Now some context just can be added to the SilcDList.
7472 Currently this list is not used in the SILC just yet, though there
7473 are a lot places where this can replace dynamically allocated
7474 tables and I will fix these places, later, to use SilcDList.
7475 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7476 and use TRQ internally).
7478 Also fixed some annoying warning messages that the original TRQ
7479 code generated. Also minor changes to TRQ's Makefile.in.
7481 * Added support for querying by Client ID to both WHOIS and
7482 IDENTIFY commands into server, as required by the protocol.
7484 * Removed method function pointers from SilcBuffer structure. They
7485 weren't used to anything and just increased the context size for
7486 no good reason. This change also made silc_buffer_alloc and
7487 silc_buffer_free functions inline functions.
7489 * Disabled command flooding detection support until it's fixed so
7490 that it accepts commands in but does not execute them more than once
7493 * Added silc_net_localhost(), to return local hostname, into
7494 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7495 that must be initialized before calling silc_client_init.
7497 * Added new function: silc_server_send_notify_on_channels to send
7498 notify messages to all channels client has joined. It is assured
7499 that the message is sent only once per client.
7501 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7502 lib/silcutil/silcutil.[ch] as silc_format function. The new
7503 function is generic and is used by server as well, not only by
7504 the logging routines.
7506 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7507 the provided version string was not acceptable. Added new function:
7508 silc_ske_check_version into lib/silcske/silcske.h. The function
7509 must be implemented by the application (client or server) and it
7510 does not reside in the SKE library. The function checks the version
7511 string remote end sent.
7513 * Added back pointers (to opaque context and to SilcSocketConnection)
7514 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7516 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7517 duplicate packet context structure.
7519 * Changed `notify' client operation to send same arguments as client
7520 receives from server except for ID's. ID's are mapped to correct
7521 ID entry and that is returned. Also, if channel entry is not sent
7522 by server but the notify is for channel the channel entry is sent
7523 to application (otherwise application doesn't know that it is for
7524 channel (library gets it from packet's Destination ID)).
7526 * Added silc_client_remove_from_channels into client library to
7527 remove a client from all channels it has joined to. Used when
7528 received SIGNOFF notify from server. Added also new function
7529 silc_client_replace_from_channels to replace old ID entry with
7530 new ID entry on all channels. Used when received NICK_CHANGE
7533 * Fixed ID Cache list handling in silc_idlist_get_client in
7534 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7535 to get (or query) client by ID.
7537 * Updated TODO list.
7539 * Added connection authentication status message defined by the
7540 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7541 support for these into the code in client and server side.
7543 * Added generic function silc_client_send_command to send any command
7544 with variable argument list. Application should use this function
7545 to send commands if the command functions provided by the library
7546 does not suite for the application's user interface needs.
7548 * Added new `failure' client operation. Application is notified about
7549 received failure packet if client is executing a protocol. In this
7550 case the protocol's execution has failed.
7552 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7553 is required by the protocol.
7555 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7556 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7559 * Added status flag to SilcSKE object to indicate realtime status
7560 of the SKE protocol.
7562 * Application receives now exactly same command reply arguments as
7563 the library receives from server. However, if ID is received the
7564 corresponding ID entry is returned to the application (eg. Client
7565 ID is mapped to correct SilcClientEntry entry and that is returned).
7566 Changed command_reply client operation due to this change.
7568 * Changed all ID's in commands and in command replys as ID Payloads.
7569 Change affected both client and server side codes.
7571 All ID's sent in SILC network (with execption of ID's in SILC
7572 Packet header) are sent in ID Payload to support variable length
7575 * Server now notifies nick changes and notifies all clients on
7576 the channels about the new nickname (about the new Client ID,
7579 * Implemented CMODE command to change channel modes. Supports all
7580 channel modes defined by the protocol specs except ban and invite
7581 lists. (Also, private channel key mode is supported but support for
7582 setting private channel key in client is missing, thus, this mode
7583 has no effect on client side (except that server requires that the
7584 client uses private channel key and normal channel traffic does not
7587 Also, invite mode works per se, but INVITE command does not work
7588 yet correctly, so you can set channel as invite only channel but
7589 inviting clients to the channel does not work (it is yet to be
7590 thought what's the best way to do it).
7592 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7593 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7594 Implemented CUMODE command to change user's mode on the channel.
7595 Supports all modes defined by the protocol specs.
7597 * Added NAMES command reply to return users modes on the channel.
7599 * Removed unnecessary and slow ciphers from lib/silccrypt.
7601 * Set SO_KEEPALIVE option to connection sockets by default.
7603 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7605 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7606 redefined the Notify Payload into protocol specs.
7608 * Added silc_id_payload_parse_id to get ID directly from raw
7611 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7614 accept searching by Client ID as well.
7616 * Added support for LEAVE and SIGNOFF notify types in client library.
7618 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7619 to parse ID Payload from raw data.
7621 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Added flags parameter into silc_ske_assemble_security_properties
7624 function in lib/silcske/silcske.[ch].
7626 * Changed notify client operation to fit better for notify messages
7627 sent by server. The notify payload received from server is now
7628 passed to the application (after parsing it to SilcNotifyPayload).
7629 It is application's responsibility to retrieve the arguments
7630 from the payload and show the message the way it wants. The message
7631 sent by server is implementation specific.
7633 * Changed public keys to comply with the protocol specification.
7634 Old public keys are not supported anymore and are not compatible.
7636 * Removed nickname from Channel Payload as the latest draft removed
7637 it. The client must resolve the nickname from the NAMES command
7638 reply received when it joined the channel.
7640 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7642 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Fixed some errors in protocol specification drafts.
7646 * Created lib/silccore/silcnotify.c to implement Notify Payload
7647 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7648 generic payloads described by protocol specifications. The file
7649 includes implementations for ID Payload and Argument Payload.
7651 * Changed Command Payload implementation to use the new Argument
7652 Payload. Changed command_xxxx_payload to command_payload_xxxx
7653 to comply with SILC coding conventions.
7655 * Added suppport for Argument Payload handling in Notify Payload
7656 implementation as protocol requires it. Added the new support
7657 into server and client lib as well.
7659 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7661 * Added support for multiple nicknames on same channel. [n] is
7662 added locally to the nickname if there are more than one same
7663 nicknames on the channel.
7665 * Server now sends all nicknames that matched WHOIS request.
7666 Client also shows the list received from server.
7668 * Added TOPIC command to client side. User can now set and show
7669 current topic on channel.
7671 * Added MOTD command to client and server. Also, server sends the
7672 motd when client connects to the server.
7674 * Changed version strings to comply ISO 8601.
7676 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7678 * Fixed protocol error handling in client library. It should now
7679 cope even if the SKE fails for some reason.
7681 * Made new protocol specification drafts for submitting to IETF.
7683 * Implemented TOPIC command to server in silcd/command.c.
7685 * Added two new notify types into lib/silccore/silcnotify.h:
7686 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7687 notify nickname change and topic setting/change on a channel.
7689 * API change of command_reply operation in client library. The
7690 application gets now the status type received from server as well.
7692 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7694 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7696 * Cras fixed and optimized the packet handling even further and
7697 it should work now. Minor change to the prototype of function
7698 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7700 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7702 * Added new function into lib/silcutil/silcschedule.[ch]:
7703 silc_schedule_with_fd to select() a specified fd. The function
7704 returns after timeout expires or data arrives or goes. The
7705 function is used by packet routines to wait that all data is
7706 received from network.
7708 * Fixed data reading from network in lib/silccore/silcpacket.c.
7709 The code now assures that all data is read from the fd and then
7710 continues packet processing. This was a bug fix since the code
7711 used to drop some data in some circumstances.
7713 * Added new function into lib/silcclient/client.[ch]:
7714 silc_client_start_key_exchange to start key exchange after
7715 connection has been established to server. The code internally
7716 now uses this funtion but its main purpose was to provide it
7717 for applications that perform their own connecting. After
7718 application has created a connection it merely calls this
7719 function to start the key exchange between client and server.
7720 The library takes care of everything else after that.
7722 Updated also lib/silcclient/README to explain the usage of
7725 * Do not send to application information that connection has
7726 been established. Application gets notified it by connect
7729 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7731 * Applied cras's patch to add silc_schedule_one function. The
7732 function runs scheduler once and returns.
7734 * Fixed the scheduler after cras messed it up. The timeout
7735 handling works now as it's supposed to work.
7737 * Added into lib/silccore/ silcnotify.h to include notify
7738 message types support. Changed silc_server_send_notify*
7739 functions, in server.[ch], to support those new notify types.
7740 Added the support for the notify types into client library,
7741 as well. Added new notify client operation into ops.h in
7744 * Changed silc_server_packet_send_to_channel to send normal
7745 packets instead of just channel message packets. The function
7746 is now used to send the notify packets to channels. It is not
7747 used to send channel message packets anymore, as server never
7750 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7751 va_arg()s as it seems to require it nowadays. I guess, if SILC
7752 is compiled with older va_arg() the new code should work anyway.
7754 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Splitted core library. Core library (lib/silccore) includes
7757 now only SILC protocol specific core (and common) components.
7758 Created new utility library (lib/silcutil) that includes more
7759 generic purpose stuff. The stuff for util library was taken
7760 from the old core library. This was minor and easy split.
7762 * Created SILC Client Library (lib/silcclient) that includes
7763 implementation of the SILC client without user interface. This
7764 was major move from silc/ directory. The code has been changed
7765 so that it is transparent towards the user interface. The
7766 silc/ directory includes now the same user interface as before
7767 and it uses the new client library. Read lib/silcclient/README.
7768 Basicly, the client library performs everything else related
7769 to SILC except user interface handling. Also, configuration
7770 files are considered to be part of user interface and library
7771 does not handle them.
7773 This change also changed a lot of structures, function naming etc.
7774 Most important change was that SilcClientWindow object was
7775 renamed to SilcClientConnection in the client library. Created
7776 also new file lib/silcclient/ops.h. Also added new files
7777 silc/local_command.[ch] and silc/client_ops.[ch].
7779 All these changes were made to make it easier for user interface
7780 designers to create what ever user interface for the SILC client
7783 It is also expected that the server will be moved to lib
7784 directory as well and SILC Server Library will be created;
7785 sometimes in the future.
7787 * Removed Local commands from lib/silccore/silccommand.h as
7788 they are application specific and new client library does not
7789 handle any of those anymore.
7791 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7792 old client implementation in silc/.
7794 * Added support for callback functions in SILC_LOG_* macros.
7795 Application can now set its own callbacks that will be called
7796 instead of using the default functions that will always print
7797 the debug messages to stderr (or stdout). Also, debugging can
7798 now be disabled by setting silc_debug to FALSE and re-enabled by
7799 setting it to TRUE. Note, that logging will still work even
7800 if debugging is disabled.
7802 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7803 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7804 silc_log_reset_debug_callbacks.
7806 * To enable debugging in silc client one must give now -d
7807 option on command line.
7809 * Changed silc_schedule_init to automatically allocate task queues
7810 if they are not allocated before calling it.
7812 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7814 * Added GMP 3.1 into math library.
7816 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7819 a channel in SILC network. The packet is used by servers and
7820 routers to notify other routers that user has left a channel.
7821 This little feature was missing until now. Added the feature
7822 to protocol specification as well.
7824 Added functions: silc_server_send_remove_channel_user and
7825 silc_server_remove_channel_user into server.[ch].
7827 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7828 lib/silccore/silcpacket.h. However, they are not implemented
7831 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7833 * Fixed joining to a channel and sending channel messages
7834 between server and router. The channel message sending should
7835 now work inside a cell.
7837 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7839 * Fixed the private message sending between server and router.
7840 The private message sending should now work inside a cell.
7842 * Added silc_server_replace_id into server.[ch] to replace
7843 existing ID in the SILC network.
7845 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7846 and silc_idlist_replace_server_id into idlist.[ch] in server.
7848 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7850 * Fixed the server to server connections. Server can again now
7851 connect to router. Router to router connections probably does
7854 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Added dynamic protocol registering support. Now protocols can
7857 registered and unregistered on the fly. Patch by cras.
7859 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7861 * Added lib/contrib directory to hold routines that some platforms
7862 don't have but are needed by SILC.
7864 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7865 into lin/contrib to provide getopt() and getopt_long() for
7866 those who don't have it.
7868 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7870 * Added AWAY command to client. When away message is set and
7871 client receives a private message packet the client automatically
7872 replies to the sender with the away message.
7874 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7875 bug seemed to be the cause of recent problems when compiling
7878 * Added version detection support to SKE protocol specification
7879 and added the new changes to the SKE implementation as well.
7880 There were other minor changes in the SKE protocol as well.
7882 Many changes in lib/silcske/silcske.[ch] and in
7883 lib/silcske/payload.[ch].
7885 * Added ^U functionality, clear input line. Patch from cras.
7887 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7889 * Mainly small bugfixes on core library. Fixed some debugging
7890 logging and buffer overflow in silclog.c.
7892 * Updated config.sub and config.guess on the distribution tree.
7894 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7896 * Added command lagging support in server. Client may execute
7897 commands now only once in two seconds.
7899 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7901 * Optimized packet reception. MAC computation and checking is now
7902 also more optimized. A lot previously duplicated code is now
7903 used as generic by both client and server.
7905 * Fixed key pair generation in clientutil.c
7907 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7909 * Added into lib/silccore/silcbufutil.[ch] new function;
7910 silc_buffer_realloc.
7912 * Moved generic packet sending/encryption functions to
7913 lib/silccore/silcpacket.[ch] from client and server. Some
7914 rewriting of the functions.
7916 * Moved all generic packet reception/decryption functions to
7917 lib/silccore/silcpacket.[ch] from client and server. The
7918 packet processing is now much cleaner in both client and server.
7919 These were major changes in both client and server.
7921 * Created many common functions in server to do packet sending.
7922 Previously code were duplicated a lot, this has been removed
7925 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7927 * Rewrote major parts of the ID cache system. Don't know
7928 whether it is better now or not but at least the API is more
7931 * Major rewrite on ID cache stuff on client because of the ID
7932 cache API changes. Added idlist.c to client.
7934 * Also major rewrite on ID cache stuff on server as well.
7935 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7936 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7937 in hand, instead they are all put into the ID cache system now.
7938 All server_idlist_* routines uses ID cache now instead of
7939 traversing its own lists (those lists does not exist anymore).
7940 SilcIDList though still exists. Also, SilcXXXEntry's are
7943 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7945 * Finally made the SKE implementation compliant to the protocol
7946 specification. All mp integers are now binary encoded as
7947 opposed being HEX encoded.
7949 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7952 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7953 functions: silc_[encode/decode]_pem. Also added function
7954 silc_encode_pem_file to PEM encode with newlines ('\n') for
7957 * SILC public keys are now encoded either PEM or binary. Same
7958 option is for private keys as well. By default private keys
7959 are binary encoded and public keys PEM encoded. Silly HEX
7960 encoding were removed.
7962 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7963 function to create fingerprints.
7965 * Fixed a bug in SHA1; does not change the original data anymore.
7967 * Partly implemented INFO command on client and server side.
7968 Fixed CLEAR command. Changes to SERVER command; show current
7969 server(s) when giving command without arguments. Added
7970 VERSION command to client.
7972 * Added check to server that unregistered connections cannot
7973 execute commands (unless it is specificly allowed).
7975 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Fixed screen refresh.
7979 * Fixed channel joining bug from client. On some circumstances
7980 client tried to join to a channel it had already joined.
7982 * Added public key verification process into client's protocol.c.
7983 The client now verifies the public key from user and saves
7984 it into ~./silc/serverkeys/ directory.
7986 Added into: clientutil.[ch]: silc_client_verify_server_key.
7988 * Changed SKE protocol's silc_ske_initiator_finish function
7989 to accept callback function that verifies the received public
7990 key. Removed old silc_ske_verify_public_key function.
7992 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7994 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7995 silc_pkcs_private_key[_data]_set.
7997 * Made the password and public authentication more cleaner in
7998 server's protocol.c.
8000 * Removed historic and obsolete protocol `channel_auth' from
8001 both client and server.
8003 * Removed wrong way of sending command status messages from
8004 server to client in server's command.c. The old way violated
8005 protocol specification.
8007 Changes to silccore/silccommand.[ch]: removed
8008 silc_command_encode_status_payload -> not needed anymore,
8009 changed silc_command_encode_payload_va to accept extra
8010 argument on variable argument list. The argument type must
8011 now be provided to the function. Also, added new function:
8012 silc_command_encode_reply_payload_va which is same as
