1 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the `say' client operation's interface to accept
4 new `type' argument to indicate the type of the message sent
5 by the library. The application may filter the library's
6 messages according the type. The affected file is the
7 lib/silcclient/silcapi.h.
9 * Added two new functions to lib/silcclient/silcapi.h:
10 silc_client_del_client and silc_client_del_client_by_id.
11 Affected file lib/silcclient/idlist.c.
13 * Moved the clientincludes.h from includes/ to silc/ and
14 serverincludes.h from includes/ to silcd/.
16 * The modes for the CMODE and CUMODE are now passed as
17 uint32 for application with COMMAND_REPLY. The affected
18 file is lib/silcclient/command_reply.c.
20 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
22 * /WHOIS without arguments shows client's own information.
23 Affected file lib/silcclient/command.c.
25 * Changed PING to not accept any arguments. The specs
26 says that client can ping only the connected server so
27 requiring an argument is not needed. Affected file is
28 lib/silcclient/command.c.
30 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
32 * Fixed a fatal bug in private message sending and reception
33 encryption and decryption when using private message keys.
34 The implementation was incorrect and did not follow the
35 specification. It causd that some of the message were
36 lost since it did not use the sending and receiving keys
37 as the protocol suggests. This has been fixed and will cause
38 incompatibilities with older clients when sending private
39 message encrypted with private message keys. Affected files
40 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
41 and various other in Irssi SILC Client.
43 Added `responder' boolean argument to the functions
44 silc_client_add_private_message_key[_ske] to indicate when
45 the key is added as responder or initiator of the key
48 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
50 * Removed the silc_ske_check_version function and created
51 a SilcSKECheckVersion callback. Added also a function
52 silc_ske_set_callbacks that is now used to set all SKE
53 callbacks. The callback functions are not given to
54 the SKE functions anymore, but this function is used to
57 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
59 * Added `silc_version' argument to the silc_client_alloc
60 to define the version of the application for the library.
61 The library will use the version string to compare it
62 against the remote host's (usually a server) version
63 string. Affected file lib/silcclient/silcapi.h
65 * Added the KE protocol context to Key Agreement context
66 in client library so that we can abort the SKE if it
67 is in process when we get timeout. Affected file is
68 lib/silcclient/client_keyagr.c.
70 * Do not resolve the client ID forever if it returns in the
71 first time that such client does not exist. This was done
72 for example with private message. Affected file is
73 lib/silcclient/client_prvmsg.c.
75 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
77 * Do not add regex.h for WIN32. The affected file
78 includes/silcincludes.h.
80 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
81 not work yet 100%. It generates the DLL's automatically
82 when compiling with --with-win32 under cygwin.
84 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
86 * lib/contrib/regex.c is not compiled on WIN32.
88 * Added silc_net_get_socket_opt function to the
89 lib/silcutil/silcnet.h.
91 * Added includes/silcwin32.h for WIN32 specific includes
94 * Do not use ptime structure or any of the posix process
95 functions on WIN32 in lib/silccrypt/silrng.c.
97 * Added silc_gettimeofday to provide generic function
98 for struct timeval on all platforms. Added the function
99 to lib/silcutil/silcutil.h.
101 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Moved the lib/silccore/silcsockconn.[ch] to the utility
104 library as they clearly belong there. As a plus side we
105 can make the actual socket connection routines platform
108 Added also new generic function silc_socket_read and
109 silc_socket_write (that used to be silc_packet_[read/write].
110 The implementation of these are platform specific.
112 * Added WIN32 specific routines of silc_socket_[read/write]
113 to lib/silcutil/win32/silcwin32sockconn.c.
115 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
117 * Added preliminary support for native WIN32 compilation under
118 cygwin (using the -mno-cygwin option for GCC) to the
119 ./configure.in.pre. The --with-win32 now prepares the
120 compilation for native WIN32.
122 * Rewrote the SILC Scheduler interface in the file
123 lib/silcutil/silcschedule.h. The scheduler is now context
124 based and does not have anymore any global static scheduler.
125 Moved the Unix scheduler to the lib/silcutil/unix/ directory
126 and created lib/silcutil/win32 directory for WIN32 based
129 * Added Unix specific network routines to the
130 lib/silcutil/unix/silcunixnet.c and the old
131 lib/silcutil/silcnet.c includes now only generic routines.
133 Added WIN32 specific network routines to the
134 lib/silcutil/win32/silcwin32net.c.
136 * Added Unix specific utility functions from the
137 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
139 * Added WIN32 SILC Scheduler to the file
140 lib/silcutil/win32/silcwin32schedule.c. The code is of course
143 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
145 * Do not handle JOIN notify in the server if the target client
146 is not registered (idata->registered == FALSE). The affected
147 file is silcd/packet_receive.c.
149 * Update the nickrec->founder in event_cumode in the Irssi SILC
150 client. Affected file irssi/src/silc/core/silc-channels.c.
152 * Fixed the CUMODE_CHANGE notify handling in the server when
153 server and router are announcing their clients on channels.
154 Now the mode changes are saved and notified correctly. The
155 affected file is /silcd/packet_receive.c.
157 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
158 They really did not replace the cache entry in the ID Cache.
159 Now they do that. Affected file silcd/idlist.c.
161 * Fixed the KICK notify handling in the Irssi SILC client to
162 update the channel records so that the kicked client does not
163 appear to be on the channel. The affected file is
164 irssi/src/silc/core/silc-channels.c.
166 * Always update the conn->current_channel when executing command
167 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
169 * Fixed the KILL notify handling in Irssi SILC client to remove
170 the killed client on all channels.
172 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * Fixed the silc_parse_command_line to remove extra spaces
175 from the start and end of the arguments. Affected file is
176 lib/silcutil/silcutil.c.
178 * Cancel and free any active protocol in the function
179 silc_server_close_connection. Affected file silcd/server.c.
181 * Cancel and free any active protocol in the function
182 silc_client_close_connction. Affected file is
183 lib/silcclient/client.c.
185 * Do not execute the KILL command for clients that are in
186 history (ie. they are not in the network). Affected file is
189 * Fixed KILL notify handling, client does not crash anymore.
190 Affected file irssi/src/silc/core/silc-channels.c.
192 * Reduced the default packet buffer size from 2048 to 1024 in
193 lib/silccore/silcpacket.c.
195 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
196 counter to the SKE context that is incresed when the SKE library
197 performs async operation outside the library. If the outside
198 process frees the SKE context and FREED status will be set
199 and the library will detect after the sync operation that the
200 libary is freed. The affected files are
201 lib/silcske/silcske[_status].[ch].
203 * Resolve the client entry information in the function
204 silc_client_channel_message to assure that NULL pointer is not
205 passed as client entry to the application. */
207 * Fixed the task timeout calculation to assure that there is
208 never negative timeouts. The affected file is
209 lib/silcutil/silcschedule.c.
211 * Fixed the channel user mode notification sending in server.
212 It was sent point-to-point to the router (or to server by router)
213 but it needs to be destined to a channel. The routines now
214 supports sending the channel user mode notifys to the channels
215 when announcing clients and channels. Affected files are
216 silcd/server.c and silcd/packet_receive.c.
218 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
219 It did not actually replace the old channel entry in the cache.
220 Affected file lib/silcclient/client_notify.c.
222 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
224 * Fixed a possible crash in silc_packet_send_prepare. It now
225 assures always that there is enough space in the buffer and
226 at the tail area of the buffer (for MAC).
228 Fixed the inbound buffer reallocation in silc_packet_read.
229 It was old code and did not handle the reallocation correctly.
232 The affected file is lib/silccore/silcpacket.c.
234 * Fixed buffer overflow in silc_parse_nickname in the file
235 lib/silcutil/silcutil.c.
237 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
239 * make install generates new server keys only if there is not
242 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
245 Added check that if the NOREPLY is set then we will not send
246 the away message. This avoids infinite loop of away messages
247 if both clients are away. The affected file is
248 lib/silcclient/client_prvmsg.c.
250 * Fixed client crash if /NICK was given without arguments.
251 Affected file lib/silcclient/command.c.
253 * Server does not send the invite list in INVITE command back
254 to the client if the list was not altered. Added this notion
255 to the protocol spec as well. Affected file silcd/command.c.
257 Fixed possible crash in INVITE command by checking the
258 value of silc_server_get_client_route command.
260 * Fixed the INVITE notify type handling. The arguments are now
261 taken in correct order and client does not crash. The affected
262 file is irssi/src/silc/core/silc-channels.c.
264 Removed the "Inviting xxx to channel" message from the
265 client library away and let the application handle it.
266 Affected file lib/silcclient/command.c. Added that message
267 to Irssi SILC client's message formats.
269 * Fixed CMODE command crash in client. It now checks the
270 amount of arguments correctly and does not crash. The affected
271 file is lib/silcclient/command.c.
273 * Do not create new channel automatically in silc_channels_join
274 but check whether the channel by that name already exists.
275 Affected file irssi/silc/core/silc-channels.c.
277 * Do not send the SERVER_SIGNOFF to router if the disconnected
278 entity was the router. Affected file silcd/server.c.
280 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
281 SILC client as it was missing from there.
283 Added the handling of the KICK notify to the Irssi SILC client
284 as it was missing. Added "you have been kicked" message to
285 Irssi SILC client's message modules formats.
287 Added the handing of the KILL notify to the Irssi SILC client
288 as it was missing. Added the kill message module formats
291 The affected file is irssi/src/silc/core/silc-channels.c.
293 * The router did not save the channel mode the server announced.
294 Affected file silcd/packet_receive.c.
296 * Fixed a possible crash in INFO command in server. If the
297 server did not provide the server info it crashed. Affected
298 file silcd/command.c.
300 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
302 * Fixed the GETKEY command in the server to check also the
303 global list. Otherwise the GETKEY would not work correctly
304 in normal SILC server. Affected file silcd/command.c.
306 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * Fixed GETKEY crash, it crashed if the command did not succseed.
310 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
313 is now real and not just an macro interface to GMP.
315 Removed the entire GMP from the source tree and imported new
316 NSS MPI library instead. Reason for removing GMP is that it is
317 extremely large and compiles extremely slow. The NSS MPI
318 is only a few files and compiles in less than 10 seconds.
319 The speed is also about the same as GMP. The MPI is imported
322 If the system has GMP installed we will still use the GMP.
323 If it is not then the NSS MPI will be compiled.
325 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * Merged a long nickname (127 characters long) crash bugfix from
328 Irssi CVS tree. Affected file irssi/src/core/misc.c.
330 * Merged a freed memory reference bugfix from Irssi CVS tree.
331 Affected file irssi/src/core/commands.c.
333 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * Added the server's public key sving and verification to the
336 server when performing the SKE. This was missing and the
337 remote server's (or router's) public key was accepted without
338 checking whether we have it previously or trust it at all.
339 Affected file silcd/protocol.c.
341 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Check in the silc_server_timeout_remote if protocol is active
344 and make sure that the protocol's final callback is called so
345 that all memory if freed. Affected file silcd/server.c.
347 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
349 * silc_server_whois_send_reply crashed the server if the nickname
350 was 127 characters long. Affected file silcd/command.c.
352 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
354 * Added sanity check to the silc_server_new_client. If the hostname
355 is provided inside username then check that the provided hostname
356 really is the same as the resolved one. If the hostname was not
357 resolved then check it from the public key. Affected file is
358 silcd/packet_receive.c.
360 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
361 if the server disconnected us and the connection is not valid
362 anymore. Affected file irssi/src/silc/core/silc-channels.c.
364 * Moved the silc_client_[chmode|chumode|chumode_char] away from
365 the library to the lib/silcutil/silcutil.[ch].
367 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Close log file after open. Affected file
370 lib/silcutil/silclog.c.
372 * Check whether sock == NULL in silc_client_send_packet and return
373 if it is. Affected file lib/silcclient/silcclient.c.
375 * Check rec->entry == NULL in the Irssi SILC Client before
376 sending the channel message. Affecte file is
377 irssi/src/silc/core/silc-servers.c.
379 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Merged a splitted window bugfix from Irssi CVS tree. The
382 affected file is irssi/src/fe-text/textbuffer-view.c.
384 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
385 It did not print nickname.
387 * Improved the distributions system a bit.
389 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
392 irssi/src/fe-text/gui-window.c.
394 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
395 to in-active server. The affected file is
396 irssi/src/silc/core/client_ops.c.
398 * Resolve the client in USERS command reply if the entry does
399 not have username resolved. The affected file is
400 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
401 command to WHOIS command to really resolve stuff. The USERS
402 is not used any more in any critical section so WHOIS can
403 be used even though it might be slower than IDENTIFY.
405 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
408 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
410 * Changed the protocol API a bit more consistent in the
411 lib/silccore/silcprotocol.[ch].
413 * Changed the following headers to ROBODoc format:
415 lib/silccore/silcpayload.h
416 lib/silccore/silcprotocol.h
417 lib/silccore/silcsockconn.h
419 All core library headers are now formatted.
421 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Fixed a bug in Irssi SILC client; do not show that you are
424 server/router operator if you really are not. Affected file is
425 irssi/src/silc/core/client_ops.c.
427 * Renamed silc_command_free_payload to silc_command_payload_free.
428 Affected file lib/silccore/silccommand.h
430 * Added silcmath.h to include the prototoypes of various routines
431 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
434 * Changed the following headers to ROBODoc format:
436 lib/silccore/silcchannel.h
437 lib/silccore/silccommand.h
438 lib/silccore/silcid.h
439 lib/silccore/silcidcache.h
440 lib/silccore/silcmode.h
441 lib/silccore/silcnotify.h
442 lib/silccore/silcpacket.h
443 lib/silcmath/silcmath.h
445 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * Added checking to the server code not to start the server if
448 ciphers and stuff are not configured properly. Affected files
449 silcd/serverconfig.[h] and silcd/server.c.
451 * Changed the layout of the header files of the public interfaces
452 in the SILC libraries. The new layout supports ROBODoc
453 documentation tool (and some others) so that it is easy to create
454 a library reference manual. All the other headers and source
455 code must still follow the CodingStyle document. Also source
456 code must not include these ROBODoc stuffs, only the headers.
457 Furthermore, all public interface headers must now be named
458 by using `silc' prefix, example: silcapi.h, silccipher.h.
459 Some files were renamed due to this. All the other headers
460 must not be used as public interfaces. I will update the
461 CodingStyle document later. Changed following headers, so far:
463 lib/silcclient/silcapi.h
464 lib/silccore/silcauth.h
465 lib/silccore/silcprivate.h
466 lib/silccrypt/silcdh.h
468 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Removed silc_client_packet_send_flush from the client library
473 as it is not needed. Affected file lib/silcclient/client.[ch].
475 * Added printing of message of unresolved authentication method
476 to the Irssi SILC client. Added it to the module formats.
477 Removed the same message from the client library.
479 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Added new distribution feature, DISTLABEL. Every distribution
482 can define own preprocessor label that can be used in the
483 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
484 file distributions, acconfig.h.pre and prepare.
486 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
488 * Added Makefile.defines_int to include the actual definitions
489 for Makefile.defines.in. Tested the new distribution system,
490 created distributions and tested installation.
492 * Added AWAY message printing to the Irssi SILC client. Added
493 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
495 * Added SCONNECT command to call the SILC's CONNECT command.
496 Cannot use CONNECT directly since Irssi uses that internally.
497 Affected file irssi/src/silc/core/silc-servers.c.
499 Added ACTION local command. It is same as ME command but takes
500 the channel as mandatory argument.
502 Rewrote some of the Irssi's help files to suite for SILC
505 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
507 * Added Makefile.defines[.in] that should for now on be included
508 in all Makefile.am file in the source tree. That file includes
509 all common compilation definitions for SILC source tree.
511 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Minor changes to the ./prepare script to change the package
514 name according the distribution name to the configure.in.
516 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
518 * Created new distribution system. Added file `distributions'
519 that defines all the distributions that can be created out of
520 the SILC source tree. The ./prepare script now reads that
521 file to determine how to prepare the distributions. The
522 first argument to the ./prepare is the name of the distribution
523 and second is the version of the distribution. If given
524 without arguments it creates the default (toolkit) distribution
525 with the default version (defined in ./prepare).
527 All Makefile.am files that are subject to the distributions
528 are now named as Makefile.am.pre. These are ./Makefile.am
529 and lib/Makefile.am. Others may be changed later.
531 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Added invite list, ban list, some key management and connection
534 error message printing to module formats in the Irssi SILC client.
536 * Added new silc_client_set_away_message to set the away message
537 that is back to the person who sent private message. The
538 affected file lib/silcclient/silcapi.h and the
539 lib/silcclient/client_prvmsg.c.
541 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Fixed the private message sending in the Irssi SILC client,
544 added local command KEY to the Irssi SILC client.
546 Added key management and key agreement message formats to the
547 irssi/src/fe-common/silc/module-formats.[ch].
549 Added USERS (alias WHO) printing, server/router operator
550 indication and LIST command printing to the module formats.
552 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Fixed channel joining notify handling, cumode notify handling
555 from Irssi SILC client.
557 * Added SILC specific module-formats to the Irssi SILC client so
558 that SILC specific message hilighting, colors etc is possible.
559 Affected file irssi/src/fe-common/silc/module-formats.[ch].
561 Added channel mode, channel user mode, actions, notices,
562 whois and whowas printing to the the module-formats.c.
564 * Fixed a bug in channel deletion in the server. The channel
565 is not left to the cache even if the channel founder auth mode
566 is set when there are no users anymore on the channel. Affected
569 * The silc_net_localhost now resolves the entire hostname including
570 the domain name. Affected file lib/silcutil/silcnet.c.
572 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * Changed the ask_passphrase client operation to be ascynchronous.
575 It has now a completion callback and a context that the
576 application must call after it has got the passphrase from
577 the user. Affected files lib/silcclient/silcapi.h,
578 lib/silcclient/protocol.c, lib/silcclient/command.c and
581 Added SilcAskPassphrase callback that the application calls
582 to deliver the passphrase to the library.
584 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
585 The public key verification and especially a certificate
586 verification is asynchronous procedure.
588 Added new SILC_SKE_STATUS_PENDING status to indicate the
589 request is pending and a callback will be called to finalize
592 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
593 indicate that remote end did not send its public key (or
594 certificate), even though we require it. Added check for this
595 condition in the SKE. This was a security bug, now fixed.
597 Defined new SilcSKEVerifyCbCompletion callback that is called
598 when the verification process is completed.
600 The affected files lib/silcske/silcske_status.h and
601 lib/silcske/silcske.[ch].
603 * Changed the verify_public_key client operation to be async
604 as well. Defined SilcVerifyPublicKey callback that is used to
605 indicate the success of the public key verification process.
607 Changed the server and client to use the new async client
610 * Changed the Irssi SILC client's internal scheduler to be called
611 twice as many times as it used to be. As a result the client
612 should be a bit faster now. Affected file is
613 irssi/src/silc/core/silc-core.c.
615 * Added support to Irssi SILC client of asynchronous public key
616 verification and passphrase inquiry. Affected file is
617 irssi/src/silc/core/silc-core.c.
619 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
621 * Do not say "You have left channel %s" in client library.
622 Moved it to the application. Affected files are
623 lib/silcclient/command.c and silc/client_ops.c.
625 * Fixed silc_client_get_clients. Command context was not
626 duplicated and was freed memory in the callback. Affected
627 file lib/silcclient/idlist.c.
629 * Do not say "you are now talking..." on JOIN command in the
630 client library. The appliation must handle it.
632 * Do not say ".. changed topic to" in command reply in the
633 client libary. The application must handle it.
635 * Fixed TOPIC command sending in the client library.
637 * Fixed a memory leak in silc_client_command_free in the file
638 lib/silcclient/command.c.
640 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Imported a modified version of Irssi client to the source tree.
643 The Irssi will be used to create a new client called
644 Irssi SILC. Imported to irssi/.
646 Added silc_core_init_finish function to the Irssi. Affected
647 file irssi/configure.in.
649 A lot changes in the Makefile.ams around the irssi tree.
651 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
653 * Do not rehash if the new size is same as the old size of the
654 hash table, in the silc_hash_table_rehash*. The affected file
655 lib/silcutil/silchashtable.c.
657 * Replaced hash_table_del_by_context calls from the server
658 (when channel->user_list and client->channels) to the
659 hash_table_del as it is sufficient and faster.
661 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Added silc_hash_table_list, silc_hash_table_get and the
664 SilcHashTableList structure to provide an alternative way to
665 traverse the hash table. The affected files are
666 lib/silcutil/silchashtable.[ch].
668 * Changed the server's idlist routines to use the hash table
669 routines to optimize the code.
671 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Replaced the client entry's `channel' list and channel entry's
674 `user_list' list to hash tables for optimized lookup. Changed
675 the code to use the hash table interface around the code.
676 Affected file lib/silcd/idlist.[ch].
678 * Added `auto_rehash' boolean argument to the function
679 silc_hash_table_alloc to indicate whether the hash table should
680 auto-rehash when it thinks is appropriate time. It will
681 increase the hash table size if the there is twice as much
682 entries in the table than the size of the table, and will
683 decrease the size if there are twice as less entries than
684 the size of the table.
686 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
688 * Fixed silc_xxx_get_supported to not crash at some circumstances.
690 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * silc_idcache_purge_by_context deletes the entry now by context
693 as it is supposed to do. Affected file lib/silccore/idcache.c.
695 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
696 client is not anymore valid (WHOWAS givens the info) and not
697 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
699 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Removed the `data' and `data_len' arguments from the ID Cache
702 interfaces and added `name' argument. ID Cache does not handle
703 anymore the binary data only a names associated with given ID.
705 * When hashing a Client ID with silc_hash_id the entire ID is
706 not hashed anymore, instead only the hash of the Client ID is
707 hashed. This way we can access the Client ID from the cache
708 with Client ID but with the hash of the ID (which is a hash of
709 the nickname) as well without any difference in performance.
711 Added also silc_idcache_find_by_id_one_ext to do one on one
712 searching when we have the actual ID. Added also function
713 silc_hash_client_id_compare. The affected files are
714 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
716 * When hashing the name associated with a ID it is always done
717 in lowercase. This way we can access the cache without worrying
718 about case-sensitivity, even though, for example nicknames are
721 * Fixed a bug in server with channel message sending. It put
722 wrong ID type as destination ID. The affected file
725 * silc_idcache_del_by_context now deletes from all hash tables
726 by context. Affected file lib/silccore/idcache.c.
728 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Changed the client library to use the new ID Cache interface.
731 Changes around the source tree.
733 * Added silc_hash_table_rehash_ext to rehash with specific
734 hash function. Affected file lib/silcutil/silchashtable.[ch].
736 * Added silc_hash_string_compare to compare two strings in the
737 hash table. Affected file lib/silcutil/silcutil.[ch].
739 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Added new function silc_idcache_del_by_context into the
742 lib/silccore/idcache.[ch].
744 * Changed the server's ID list routines to use the new ID Cache
745 interface. Changes around the source tree.
747 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Added silc_hash_table_del[_by_context]_ext functions in to the
750 lib/silcutil/silchashtable.[ch].
752 Removed silc_hash_table_find_all* routines and added new
753 silc_hash_table_find_foreach to replace them.
755 Added silc_hash_table_replace_ext function as extended
756 replacing function. Separated the simple hash table interface
757 from the extended hash table interface in the file
758 lib/silcutil/silchashtable.h.
760 * Fixed minor bugs and changed it to use some of the new
761 hash table functions in lib/silccore/idcache.c
763 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Added new function silc_hash_table_find_all to return all keys
766 in the hash table by the specified key. As the hash table is
767 collision resistant it also makes it possible to have several
768 duplicate keys in the hash table. This function may be used to
769 find all of the keys from the hash.
771 Added user_context arguments to the SilcHashFunction,
772 SilcHashCompare and SilcHashDestructor to deliver user specified
775 Added new fuctions silc_hash_table_find[_all]_ext to do
776 extended lookup with specified hash and compare functions and
777 specified user contexts.
779 Added new function silc_hash_table_add_ext to add the key
780 with specified hash function and user context.
782 Added new function silc_hash_table_foreach to traverse all
783 entrys in the hash table. Added SilcHashForeach callback
786 Added new function silc_hash_table_del_by_context to delete
787 the entry only if the context associated with the key matches.
789 Affected files are lib/silcutil/silchashtable.[ch].
791 * Removed silc_hash_[server/client/channel]_id and added just
792 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
793 silc_hash_id_compare to compare two ID's using as the hash table
794 comparison function. Added also silc_hash_data to hash
795 binary data and silc_hash_data_compare to compare it.
797 * Removed silc_idlist_find_client_by_hash as it is not needed
798 anymore. Affected file silcd/idlist.[ch].
800 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
801 to use internally the SilcHashTable. The new ID Cache is a lot
802 faster than the old one. Some of the ID Cache interface was also
803 rewritten and obsolete and stupid functions were removed.
805 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * Added entry_count field to the SilcHashTable to keep the number
808 of the entries in the table. Implemented the function
809 silc_hash_table_rehash. Added new function
810 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
812 Fixed a minor bug in silc_hash_table_free.
814 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
815 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
816 into the lib/silcutil/silcutil.[ch].
818 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Implemented a collision resistant hash table into the
821 lib/silcutil/silchashtable[ch]. See the header and the source
822 for the SilcHashTable API.
824 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
826 * Merged dotconf version 1.0.2 into lib/dotconf.
828 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
830 * Do not compile anything in lib/silcsim/* if the SIM support
831 is not enabled. The tree should now compile without problems
834 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Compiled the SILC under cygwin. Compiled and tested briefly
837 without problems. More tests needed. The SIMs didn't compile
840 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
842 * Fixed possible crash in silc_get_username in the
843 lib/silcutil/silcutil.c.
845 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Fixed a va_arg in silc/client_ops.c.
849 * Oops, RC5 routines were named AES and caused some problems
850 when not using SIM's. Affected file lib/silccrypt/rc5.c.
852 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Added new SilcIDIP structure into the lib/silccore/id.h and
855 replaced the old `ip' fields from all SILC ID's to that type.
856 This is a step towards IPv6 support.
858 The silc_id_get_len takes now the ID as an extra argument.
859 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
860 both IPv4 and IPv6 based ID's.
862 The affected files are lib/silccore/id.[ch] and other files
863 around the tree using these routines.
865 * Removed the ID length arguments in server from various
866 silc_server_send_notify_* routines -> they are not needed
869 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Fixed memory leak in silc_encode_pem_file in the file
872 lib/silcutil/silcutil.c.
874 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Check minor version as well in the SKE. Affected files are
877 silcd/protocol.c and lib/silcclient/protocol.c.
879 * Added --identifier option to the server so that an identifier
880 can be when creating the public key for the server. Affected
881 file is silcd/silcd.c.
883 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
884 lib/silccrypt/silcpkcs.c.
886 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
888 * Register default ciphers and stuff when using -C option with
889 the server. Affected file sildc/silcd.c.
891 * Put back the servers public key filename format, it is better
892 than the new one. For now, the client keys are saved with the
893 new filename format. The affected file silc/client_ops.c.
895 * Implemented the Cipher API for the rest of the ciphers that
896 did not implement it or implemented it the wrong way.
898 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Register default ciphers and stuff when using the -S option
901 in the client. Affected file silc/silc.c. Same also when
902 creating new key pair with -C option.
904 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
906 * Fixed the silc_verify_public_key client operation function to
907 save the public keys differently. The fingerprint is now
908 used as filename and not the hostname. This way also the
909 client keys are saved uniquely and not with hostnames. The
910 affected file is silc/client_ops.c.
912 * Trimmed the silc_hash_fingerprint function to remove extra
913 whitespaces from the end of the fingerprint. The affected
914 file is lib/silccrypt/silchash.c.
918 * Added silc_cipher_register_default function to register all
919 default ciphers. It can be used when configuration files
920 does not exist and the application does not want any specific
921 ciphers in any specific order.
923 The SilcDList is now used as silc_cipher_list dynamically
924 allocated cipher list. Removed the static list all together
925 and now all ciphers must be allocated to the dynamic list.
926 The silc_cipher_alloc routine was changed to check only the
929 All silc_cipher_* routines that used to return int returns
932 The affected files lib/silccrypt/silccrypt.[ch].
934 * The same thing was done to silc_hash_* as for silc_cipher_*
935 routines. Affected files lib/silccrypt/silchash.[ch].
937 * The same thing was done to silc_pkcs_* as for silc_cipher_*
938 routines. Affected files lib/silccrypt/silcpkcs.[ch].
939 Added also silc_pkcs_[un]register[_default] functions.
940 Removed the data_context from the PKCS API.
942 * Added silc_hmac_register_default function to register default
943 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
944 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
945 to unregister all hmacs at once.
947 * Register the default ciphers, hash functions, PKCSs and HMACs
948 if client's configuration file does not exist. The affected
951 * The client did not load the hash functions from the SIM
952 modules at all. Added support for this. Affected file is
955 * When decoding public key with silc_pkcs_public_key_decode, check
956 the supported algorithm only if PKCS are registered. Affected
957 file lib/silccrypt/silcpkcs.c. The same was done with the
958 silc_pkcs_private_key_decode.
960 * Fixed the SILC List routines to keep the list always in order.
961 It used to change the list's order when traversing the list but
962 not it preserves the order. Affected file lib/trq/silclist.h.
964 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Added the client library to use the SilcSocketConnection's
967 reference counter (by silc_socket_dup) to prevent the bug that
968 the socket object may be freed underneath async operation.
970 * The name resolv library checking fixes in the configure.in.pre.
973 * Created new version of the protocol drafts for future
974 development. The -03 drafts are the ones that will be changed
975 in the trunk now and the -02 will remain as they are.
977 * Send list of CUMODE notifys to the router when announcing
978 the channel users to the router. Affected file silcd/server.c.
979 If the router receiving channel founder CUMODE for a channel
980 that already has channel founder it will send CUMODE notify
981 to the sender to remove the channel founder rights from the
982 announced client. Affected file silcd/packet_receive.c.
984 * The CUMODE notify may now use Server ID as well as the entity
985 who changes the mode. Updated protocool specs.
987 * Updated INSTALL and README files.
989 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * New web pages in the http://silc.pspt.fi. The pages was
996 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Implemented the [DenyConnectin] config section in the server.
999 Added silc_server_config_denied_conn to check whether incoming
1000 connection is denied. Affected file silcd/serverconfig.[ch].
1002 * Do not check the ports when checking the incoming configuration
1003 data if the port is 0, meaning any. Affected file is
1004 silcd/serverconfig.c.
1006 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1008 * Fixed buffer overflow in silc_string_compare in the file
1009 lib/silcutil/silcutil.c.
1011 * Fixed double free in silc_server_command_leave in the file
1014 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1016 * Fixed the version checking in the server. Affected file is
1019 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1021 * Fixed the configuration data fetching when accepting new
1022 connections in the server. Affected file silcd/server.c.
1024 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Added `sender_entry' argument to the function
1027 silc_server_packet_relay_to_channel so that we can check
1028 whether some destination actually belongs to the same route
1029 the sender belongs (ie, we must not resend the packet to the
1030 sender). Affected file silcd/packet_send.[ch].
1032 * Added `servername' field to the SilcClientEntry in the server
1033 to hold the name of the server where client is from. Affected
1034 file is silcd/idlist.h.
1036 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * Moved the channel message encrypting in the router betwen
1039 router connections from silc_server_channel_message to the
1040 silc_server_packet_relay_to_channel since we want to check
1041 whether we have anybody channel before encrypting anything.
1042 Affected files silcd/packet_[receive/send].c.
1044 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * Fixed the [AdminConnection] server config section to support
1047 multiple entries. Affected file silcd/serverconfig.c.
1049 * Added support into the server to check the validity of the
1050 incoming connection before executing any KE or authentication
1053 * The connection configuration is now saved to the KE and
1054 connection auth protocol contexts and not fetched anymore in
1055 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1057 * The local hosts listenning address and port is also resolved
1058 now when starting the server. We want to have the socket object
1059 to include the real address and port for the listener. Added
1060 new function silc_net_check_local_by_sock into the files
1061 lib/silcutil/silcnet.[ch].
1063 * Fixed a broadcast bug in server -> do not broadcast if we
1066 * Fixed a routing bug. Do not route broadcast packets ever.
1067 Broadcast packets must be processed always and not routed since
1068 they may be destined to some other host than yourself and thus
1069 would get routed without no good reason. Affected file is
1072 * Added function silc_server_config_is_primary_route to check
1073 whether primary router connection has been configured (a router
1074 configuration that we are initiating). If there is not, we
1075 will assume that there is only two routers in the SILC network
1076 and we will use the incoming router connection as our primary
1077 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1079 * Changed the order of the broadcasting. Broadcast _after_ the
1080 packet has been processed not before. Affected file is
1083 * Fixed a [ClientConnection] parsing bug. The port was never
1084 parsed correctly thus resulting to port 0. Affected file
1085 silcd/serverconfig.c.
1087 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1088 argument and did not set the broadcast packet flag. Affected
1089 file silcd/packet_send.c. Fixed same bug in the function
1090 silc_server_send_notify as well.
1092 * If we receive NEW_ID packet for our own ID in the server, ignore
1095 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Removed the nickname from the Private Message Payload.
1100 Updated the code and the protocol specs.
1102 * Updated protocol specs for submitting to the IETF.
1104 * Tweaked the Random Number Generator a bit. Affected file
1105 lib/silccrypt/silcrng.c. Exported a new function
1106 silc_rng_[global]_add_noise which can be used to add more
1109 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1111 * Do not parse packets with different timeout when protocol
1112 is active -> may cause problem with rekey. Affected file
1115 * When server receives signoff notify it must not create
1116 new channel key if the client is on any channels since the
1117 sender of the signoff notify will create it.
1119 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Added printing of error messages during SKE protocol from the
1122 failure packet sent by server during SKE. Affected file
1125 * Removed the client's failure_callback handling with timeout
1126 and handle it immediately when received.
1128 * The SKE library returned wrong type in SUCCESS and FAILURE
1129 packets. They must be 32 bit MSB not 16 bit MSB.
1131 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Ok, rewrote the logic of the re-key and now it seems to work.
1134 I tested it on high traffic with frequent re-keys without
1135 problems. Added hmac_receive (and renamed hmac to hmac_send)
1136 in SilcClientConnection in lib/silcclient/client.h and
1137 in SilcIDListData in silcd/idlist.h. Also, removed the
1138 SilcPacketParserContext's cipher and hmac fields as they are
1139 not needed anymore and actually caused some problems when
1140 the ciphers and hmac's changed underneath the packet parser.
1142 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * If re-key protocol is active then process the incoming packets
1145 synchronously since we must assure that icoming packets encrypted
1146 with the old key is processed before the new keys is set to
1147 use. This is true other packets than for REKEY packets.
1148 Affected file silcd/server.c. The same was done to client library
1149 as well, affected file lib/silcclient/client.c.
1151 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Fixed bug in client and server to accept the force send if
1154 the packet is send from silc_[server/client]_packet_process
1155 function. Otherwise the packets are never delivered, oops.
1157 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1159 * Disable force sending of packets when REKEY protocol is active.
1160 We must assure that no packet is sent directly when rekey is
1161 performed. All packets must be sent through packet queue.
1162 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1163 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1164 function is silc_[server/client]_packet_send_real to check
1167 * Replaced the SIM paths from example config files to
1168 /usr/local/modules. Also, make install creates now
1169 /usr/local/silc/logs directory to hold all the SILC server
1172 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Made the configure.in.pre work on Solaris. Patch by salo.
1176 * Made all ciphers compatible with non-x86 machines. Defined
1177 CBC mode macros into lib/silccrypt/ciphers_def.h.
1179 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Fixed the make install.
1183 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1185 * When MAC computation fails the silc_packet_decrypt returned 0
1186 even though it was supposed to return -1. Fixed this. The
1187 affected file is lib/silccore/silcpacket.c.
1189 * Do not replace the config files in /etc/silc (in make install)
1190 if they already exist. Affected file ./Makefile.am.
1192 * Do not send re-key packets immediately but through packet queue.
1193 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1195 * Changed silc_net_check_host_by_sock to return FALSE if the
1196 IP/DNS could not be resolved. Though, it returns the IP address
1197 now even if it could not resolve it (but returns also FALSE).
1198 Affected file lib/silcutil/silcnet.[ch].
1200 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Added silc_pkcs_decode_identifier to decode the public key's
1203 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1204 Added also silc_pkcs_free_identifier. Added also new context
1205 SilcPublicKeyIdentifier.
1207 * Added -S option to the silc client. It is used to dump the
1208 contents of the specified public key file.
1210 * Changed the PKCS api to return the public key length when
1211 setting the public key.
1213 * Fixed a fatal bug in the public and private key file loading.
1214 Affected file lib/silccrypt/silcpkcs.c.
1216 * Execute the packet parsing for client with zero (0) timeout
1217 if the protocol is active. Affected file silcd/server.c.
1219 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Made the key generation options to the silcd program. Added
1222 -C option, equivalent to client's option.
1224 * Added new [ServerKeys] config section to the server. It
1225 configures the server's public and private key.
1227 * Defined generic Public Key Payload into the protocol
1228 specification to send specific type of public keys and
1231 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1232 public key or certificate.
1234 * Implemented the GETKEY command to the server and to the
1235 client library and on user interface.
1237 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Made preliminary `make install' work.
1241 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Added SilcServerRekey context into silcd/idlist.h.
1245 * Added the PFS support as defined in the specification to the
1246 SKE protocol. Affected files lib/silcske/*.c.
1248 * Added `ske_group' field to the SilcServerRekey context to hold
1249 the number of the SKE group that is used with PFS in re-key.
1250 Affected file silcd/idlist.h.
1252 * Added PFS re-key support to the server. Affected file is
1255 * Added silc_protocol_cancel to cancel execution of the next
1256 state of the protocol. Affected file is
1257 lib/silccore/silcprotocol.[ch].
1259 * Added the re-key support with and without PFS to the client
1260 library. Re-key is performed once in an hour, by default.
1262 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1263 Added silc_client_rekey_callback and silc_client_rekey_final.
1264 Affected files are lib/silcclient/protocol.[ch] and
1265 lib/silcclient/client.[ch].
1267 * Removed the `hmac_key' and `hmac_key_len' fields from the
1268 SilcClientConnection structure; not needed. Affected file is
1269 lib/silcclient/client.h.
1273 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Do not ask whether user wants to use the negotiated private key
1276 for private messages, just use it. Affected file is
1277 silc/local_command.c.
1279 * Added `send_enc_key' and `enc_key_len' fields to the
1280 SilcIDListData structure since they are needed in the re-key
1281 phase. Affected file is silcd/idlist.[ch].
1283 * Implemented the simple re-key protocol into the server.
1284 Affected files silcd/server.c and silcd/protocol.[ch]. The
1285 re-key will be performed once in an hour, by default.
1287 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1288 Added silc_server_rekey, silc_server_rekey_callback and
1289 silc_server_rekey_final.
1291 * Removed Tunneled flag from the protocol. Updated the code
1292 and the specifications.
1294 * Adde `pfs' field to the SilcIDListData to indicate whether
1295 the PFS is to be performed in the re-key. Affected file is
1298 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1301 int64 of at least the xintXX size. If void * is less that 4
1302 bytes uint32 * will be used. Defined bool as boolean.
1304 * Changed _ALL_ unsigned long and unsigned int to uint32,
1305 unsgined short to uint16 in the source tree.
1307 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1308 not handle clients that has entry->data.registered == FALSE.
1309 They are not in the network anymore. Affected file is
1312 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * Implemented the sending of the SERVER_SIGNOFF notify in the
1315 server. Affected file is silcd/server.c.
1317 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1318 Added also silc_notify_payload_encode_args into the
1319 lib/silccore/silcnotify.[ch].
1321 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1322 Affected file silcd/packet_receive.c.
1324 * Implemented the SERVER_SIGNOFF notify handling in the client
1325 library. Affected file lib/silcclient/client_notify.c. Also,
1326 implemnted the printing of the SERVER_SIGNOFF info to the
1327 application. Affected file silc/client_ops.c.
1329 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1330 if the deleting was successful. Affected file silcd/idlist.[ch].
1332 * Added support for public key authentication in the connection
1333 authentication protocol in the client library. Affected file
1334 lib/silcclient/protocol.c.
1336 * Changed the server's silc_idlist_get_clients_by_* interface
1337 to support already allocated array so that new entries may be
1338 added to pre-allocated array. Affected file silcd/idlist.[ch].
1339 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1340 and command replies.
1342 * All command reply functions in the server now calls the
1343 pending command callback even if error occured. This way the
1344 error will be delivered to the client as well. Affected files
1345 silcd/command.c and silcd/command_reply.c.
1347 * Fixed INFO command to return local server's info if no server
1348 was provided. Affected file lib/silcclient/command.c.
1350 * Removed RESTART command for good. Updated the code and the
1353 * Rewrote parts of the task system. It is a bit simpler now.
1354 Removed unsued task priorities. The affected files are
1355 lib/silcutil/silctask.[ch].
1357 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Moved the USERS printing from the library to the application.
1360 Affected files lib/silcclient/command.c and silc/client_ops.c.
1362 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1366 * Added channel key re-key support. The re-key is perfomed
1367 only by the router and is done once in an hour. Added `rekey'
1368 field to the SilcChannelEntry in the server. Affected files
1369 silcd/server.c and silcd/idlist.h.
1371 * Added silc_task_unregister_by_context into the file
1372 lib/silcutil/silctask.[ch].
1374 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1376 * Added SILC_UMODE_GONE mode to indicate when the client is not
1377 present in the SILC network. Added also support to the local
1378 command AWAY that will set this mode. Added support of showing
1379 "xxx is gone" in WHOIS command. The USERS command shows the
1380 gone status as well.
1382 * Fixed setting server and router operator privileges in the
1383 server's UMODE command. Affected file silcd/command.c.
1385 * Merged the SKE KE1 and KE2 payloads into one payload. The
1386 new KE payload is equivalent to the old KE2 payload.
1388 Cleaned up the SKE Start Payload parsing. It now uses the
1389 simple buffer unformatting to do the parsing. A lot faster
1392 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1393 to the SKE that is used to indicate whether both of the SKE
1394 parties should perform authentication. By default only the
1395 responder performs authentication. By setting this flag also
1396 the initiator must do authentication. By default it is unset
1397 since in normal SKE case, client to server connection, only
1398 the responder should do authentication. When doing SKE between
1399 two clients both should perform authentication. Updated the
1400 code and the protocol specs.
1402 * A little fix to IDENTIFY command in the server. Search the
1403 client first by hash not nickname. Affected file is
1406 * Fixed the silc_client_close_connection to support closing
1407 the client to client connections wihtout deleting too much
1408 data. Affected file lib/silcclient/client.c.
1410 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1411 are received if protocol used to be active but is not anymore
1412 the application would crash due to NULL pointer dereference.
1413 Affected files silcd/server.c and lib/silcclient/client.c.
1415 * Added `hash' field to the SilcClientConnection to include
1416 the hash function negotiated in the SKE protocol.
1418 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1419 to set the channel founder authentication data. A client can
1420 claim the founder rights later by providing the authentication
1421 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1422 This way the channel founder can regain the channel founder
1423 privileges even it is left the channel. This works only on
1424 local server and the client must be connected to the same
1425 server to be able to regain the founder rights. Updated the
1426 protocol specs accordingly.
1428 Added support to the CMODE command in the client to set the
1429 founder auth data. Read the README to see how to set it.
1431 Added support to the CUMODE command to claim the founder
1432 rights. Read the README to see how to do it.
1434 Added support for the founder authentication to the Channel
1435 Entry in the server. Affected file silcd/idlist.h.
1437 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1438 server's CMODE command. Affected file silcd/command.c.
1440 * Added the following new functions into lib/silccore/silcauth.[ch]:
1441 silc_auth_get_method and silc_auth_get_data.
1443 * The server now saves the remote hosts public key to the
1444 SilcIDListData pointer. Affected file silcd/protocol.c.
1446 * The normal server now does not remove the channel entry from
1447 the cache if the founder authentication data is set. It used
1448 to remove it if the founder was the last one on the channel on
1449 the server and left the channel. The auth data is saved and
1450 if the channel is re-joined later the old entry is used with
1451 the old auth data. Affected files silcd/command_reply.c and
1454 * Removed the `pkcs' field from the SilcIDListData structure
1455 in the server; it is not used. Affected file silcd/idlist.h.
1457 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1459 * Fixed packet processing on slow links. Partial packets were
1460 never re-processed because the incoming data buffer was cleared
1461 by the application. Application must not directly clear the
1462 sock->inbuf, the packet processing routines handle it. Fixed
1463 this in client library and in server.
1465 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1467 * Fixed the WHOIS and IDENTIFY send reply function to really
1468 check whether to send list or just one entry. Affected file
1471 * Cleaned up the LEAVE command's channel key distribution. The
1472 affected file silcd/command.c.
1474 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1475 can enforce the channel mode as well. In that case the ID
1476 includes the ID of the server. The code now enforces the
1477 mode change if the router have different mode than the server.
1479 * The notify client operation with CMODE_CHANGE notify can now
1480 return NULL client_entry pointer if the CMODE was not changed
1481 by client. Application must check for this.
1483 * Added <Server ID> argument to INFO command to support server
1484 info fetching by Server ID.
1486 * Added silc_server_announce_get_channel_users to get assembled
1487 packets of channel users of the specified channel. Affected
1488 file silcd/server.[ch].
1490 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1491 was freed underneath the ID Cache.
1493 * Re-announce clients when the server received CHANNEL_CHANGE
1494 notify from the router. Affected file silcd/packet_send.c.
1496 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1499 crashed since it did not handle the fact that there is no cipher
1500 called "3" and didn't check the error condition. Now fixed.
1502 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1503 flag. It can be used to send message requests.
1505 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1507 * Implemented the RESTART command in the client.
1509 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1510 notice type messages. Added notice printing to the user
1513 * The channel keys are not re-generated if the channel's mode
1514 is PRIVKEY, ie private key on the channel exists. Affected
1515 files silcd/server.c and silcd/command.c.
1517 * Fixed a little bug in channel message delivery when channel
1518 private keys are set in the server. Affected file is
1519 silcd/packet_send.c.
1521 * Changed the setting on channel->on_channel = TRUE from the
1522 silc_client_save_channel_key to the JOIN command reply. The
1523 key payload is not received if the private channel key is set.
1524 Affected file lib/silcclient/command_reply.c and the
1525 lib/silcclient/client_channel.c.
1527 * When the CMODE_CHANGE notify is sent and the channel private
1528 key mode is removed the channel key must be re-generated in
1529 other cells as well. Added this support for the router in the
1530 silcd/packet_receive.c.
1532 * Added new local command NOTICE to send notice message on
1533 channel. Affected file silc/local_command.[ch].
1535 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Added new local command ME to the client. It is used to send
1538 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1539 some action. Affected file silc/local_command.[ch].
1541 * Changed channel_message and private_message client operations
1542 to deliver the message flags to the application. Added also
1543 the `flags' arguments to the silc_client_send_channel_message
1544 and silc_client_send_private_message functions. Affected file
1547 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1549 * Redefined the Private Message Payload to support private message
1550 keys and to support the new private message flags. Updated
1551 the protocol specs. Flags makes it possible to have for example
1552 CTCP style messages.
1554 * Added new type SilcPrivateMessagePayload and defined an API
1555 for it in the lib/silcclient/silcprivate.[ch].
1557 * Tested private message private keys successfully. Tested the
1558 private message key set, unset and list commands with the new
1561 * Redefined the Channel Message Payload to include the channel
1562 message flags (equal with private message flags) to support
1563 for example CTCP style messages.
1565 * Defined some of the message (for channel and private message)
1566 flags. Updated the protocol specs and added the flags to the
1567 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1569 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Added SilcKeyAgreementStatus type to the key agreement routines
1572 to indicate the current status and error if one occured.
1573 The status types are defined in the lib/silcclient/silcapi.h.
1575 * Added new local command KEY that is used to set and unset private
1576 keys for channels, set and unset private keys for private messages
1577 with remote clients and to send key agreement requests and
1578 negotiate the key agreement protocol with remote client. The
1579 key agreement is supported only to negotiate private message keys,
1580 it currently cannot be used to negotiate private keys for channels,
1581 as it is not convenient for that purpose.
1583 * Fixed a minor pending callback setting bug in the function
1584 silc_client_get_client_by_id_resolve, now the function works.
1585 Affected file lib/silcclient/idlist.c.
1587 * Added function silc_net_get_local_port to get local bound
1588 port by socket. Added to lib/silcutil/silcnet.[ch].
1590 * Added `sockets' and `sockets_count' fields to the SilcClient
1591 object. They hold the sockets of the listenning sockets in
1592 the client. Listenning sockets may be for example the key
1593 agreement server. Affected file lib/silcclient/client.[ch].
1594 Added functions the silc_client_add_socket and the
1595 silc_client_del_socket. They are exported to the application
1598 * Added ~./silc/clientkeys to support other client's public keys.
1600 * Renamed verify_server_key client operation to verify_public_key
1601 and added one argument to indicate the type of the connection
1602 (server, client etc.).
1604 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Added silc_server_connection_auth_request to handle the
1607 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1608 silcd/packet_receive.[ch].
1610 * Added silc_server_send_connection_auth_request into the
1611 silcd/packet_send.c to send the connection auth request packet.
1613 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1616 * Fixed the public key authentication in responder side in the
1617 server. The `auth_data' pointer includes the SilcPublicKey
1618 not the path to the public key. Affected file silcd/protocol.c.
1620 * Implemented the public key authentication in the initiator side
1621 in the server. Affected file silcd/protocol.c.
1623 * Removed the [RedirectClient] config section from the server
1624 configuration. Is not needed and I don't want to implement it.
1626 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Cleaned up the CMODE command in the server. It now works
1629 correctly and supports all the modes defined in the protocol.
1630 Affected file is silcd/command.c.
1632 * Added `hmac_name' field to the SilcChannelEntry in the server
1633 to hold the default HMAC of the channel. It can be set when
1634 creating the channel (with JOIN command). Affected files
1637 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1638 type to indicate the change of the current cipher and hmac
1639 on the channel. Client can safely ignore the <cipher> argument
1640 (if it chooses to do so) since the CHANNEL_KEY packet will
1641 force the channel key change anyway. The <hmac> argument is
1642 important since the client is responsible of setting the new
1643 HMAC and the hmac key into use.
1645 * Fixed the CMODE command in the client library as well.
1647 * Tested CMODE command in router environment successfully.
1649 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Show the version of the remote client (or server) when connecting
1652 to the server. It is logged to the log file. Affected file
1653 is silcd/protocol.c.
1655 * Fixed the KILLED notify handling in the client library. The
1656 client must be removed from all channels when receiving the
1659 Also, do not remove the client entry when giving the KILL
1660 command but when the KILLED notify is received.
1662 * Removed silc_idlist_find_client_by_nickname from the server.
1663 Not needed anymore. Affected files silcd/idlist.[ch].
1665 * Implemented the CHANNEL_CHANGE notify type handling to the
1666 server. Affected file silcd/server.c.
1670 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1684 * Added function silc_server_get_client_resolve to find the
1685 client entry by ID from all ID lists and then resolve it
1686 (using WHOIS) if it cannot be found. Affected file is
1689 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Implemented the BAN command to the client library.
1693 * The JOIN command in the server now checks the invite list
1696 * Changed the silc_command_reply_payload_encode_va and the
1697 silc_command_payload_encode_va to support that if argument is
1698 NULL it ignores and checks the next argument. Affected file
1699 lib/silccore/silccommand.c.
1701 * Added silc_server_send_notify_ban to send the BAN notify
1702 type between routers.
1704 * Chaned the silc_notify_payload_encode to support that if
1705 argument is NULL it ignores and checks the next argument.
1706 Affected file lib/silccore/silcnotify.c.
1708 * Tested ban lists in router environment successfully.
1710 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Implemented BAN command to the server, in silcd/command.[ch].
1714 * Removed the BAN and INVITE_LIST modes from the CMODE command
1717 * Added function silc_string_match to regex match two strings.
1718 Affected files lib/silcutil/silcutil.[ch].
1720 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Redefined parts of the SilcChannelEntry in the server to support
1723 the new ban and invite lists.
1725 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1727 * Redefined the INVITE command. The same command can be used to
1728 invite individuals to the channel but also to manage the invite
1729 list of the channel (to add to and remove from the invite list).
1730 Updated the protocol specs.
1732 * Added new command SILC_COMMAND_BAN that can be used to manage
1733 the ban list of the channel. Updated the protocol specs.
1735 * Removed the channel modes: the SILC_CMODE_BAN and the
1736 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1737 in the CMODE command. The equivalent features are now available
1738 using INVITE and BAN commands. Updated the protocol specs.
1740 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1741 in the network about change in the current ban list. The notify
1742 type is not used by the client.
1744 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1745 support the invite lists.
1747 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1749 * Added new function silc_string_regexify that converts string
1750 including wildcard characters into regex string that can
1751 be used by the GNU regex library. Added into the file
1752 lib/silcutil/silcutil.[ch].
1754 Added silc_string_regex_combine to combine to regex strings
1755 into one so that they can be used as one regex string by
1756 the GNU regex library. Added into the file
1757 lib/silcutil/silcutil.[ch].
1759 Added silc_string_regex_match to match two strings. It returns
1760 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1762 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Imported GNU regex to the soruce tree into lib/contrib.
1765 Fixed some compiler warning from the regex.c.
1767 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * Fixed MOTD command in the server to work in router environment.
1771 * Fixed the MOTD command in the client library to support
1772 the server argument in the command.
1774 * Added `nickname_len' argument to the silc_idlist_add_client
1775 in the server, as the `nickname' argument may be binary data
1778 * Added silc_idlist_get_channels to return all channels from
1781 * Implemented LIST command to the server. Affected file is
1784 * Implemented the LIST command to the client library and on the
1787 * Added [<user count>] argument to the LIST command reply.
1788 With private channels the user count is not shown.
1790 * Updated TODO and README.
1792 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * The client entry's data.registered must be TRUE even with
1795 global client entry on global client list. The data.registered
1796 is used to check whether the client is anymore in the network,
1797 for example with WHOWAS command so it must be valid.
1799 * Fixed the WHOWAS command in the server. It now actually works
1800 in router environment. Added function into silcd/command_reply.c
1801 silc_server_command_reply_whowas_save.
1803 * Added silc_idlist_purge function to the silcd/idlist.c
1804 to periodically purge the ID Cache.
1806 * Fixed INFO command in the server. It works now in router
1807 environment. Added <server name> argument to the INFO command
1808 reply. Updated the protocol specs.
1810 * Fixed minor bug in silc_idcache_purge to not purge if the
1811 expire value is zero.
1813 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1814 they were buggy because of the WHOWAS information.
1816 * Fixed local command MSG to handle the async resolving of
1817 the remote client properly. It used to fail the first MSG.
1818 Affected file silc/local_command.c.
1820 * Added `data_len' field to SilcIDCache context.
1822 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Update TODO. Todo in commands in the server.
1826 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1828 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1829 used by routers as broadcast packet to inform other routers
1830 about the changed user mode.
1832 Implemented the notify handling in the server. Affected file is
1833 silcd/packet_receive.c. Added the function
1834 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1836 * Added new generic Channel Payload and deprecated the New Channel
1837 Payload. The New Channel Payload is now the generic Channel
1840 * Added new argument `mode' to the silc_server_send_new_channel
1841 as it is required in the Channel Payload now.
1843 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1844 and created a new and real SilChannelPayload to represent the
1845 new generic Channel Payload. Implemented the encode/decode
1846 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1848 * Added silc_server_get_client_channel_list to return the list
1849 of channels the client has joined for WHOIS command reply.
1850 Affected file silcd/server.[ch].
1852 * Implemented the channel list sending in the WHOIS command reply
1853 in server and in the client.
1855 Implemented the channel list displaying on the user interface
1856 as well. Affected file silc/client_ops.c.
1858 * Added silc_channel_payload_parse_list to parse list of Channel
1859 Payloads. It returns SilcDList list of SilcChannelPayloads.
1860 Client for example can use this function to parse the list of
1861 channels it receives in the WHOIS command reply. The caller
1862 must free the list by calling silc_channel_payload_list_free.
1863 Affected files lib/silccore/silcchannel.[ch].
1865 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Added one new argument <user mode> to the WHOIS command reply
1868 to return the mode of the user in SILC. Updated the protocol
1871 Implemented it to the server and client.
1873 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1875 * Fixed the mode printing on the user interface on joining.
1876 Affected file silc/client_ops.c.
1878 * Implemented the UMODE command and user modes in general to the
1879 client library and to the user interface.
1881 * Implemented the UMODE command to the server.
1883 * The server now sends UNKNOWN_COMMAND error status if client sends
1884 unknown command. Affected file silcd/command.c.
1886 * All server commands now handle the command identifier the right
1887 way when sending the command reply to the client. The client can
1888 use to identify the command replies with the identifier.
1890 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * Added silc_server_get_client_route to resolve the route to
1893 the client indicated by the client ID. Affected file is
1896 * Added silc_server_relay_packet as general function to relay
1897 packet to arbitrary destination. This deprecates functions
1898 like _send_private_message_key, _relay_notify etc. Affected
1899 file is silcd/packet_send.[ch].
1901 Removed silc_server_send_key_agreement,
1902 silc_server_send_private_message_key and
1903 silc_server_packet_relay_notify functions from the file
1904 silcd/packet_send.[ch].
1908 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1909 server. Affected file silcd/packet_receive.[ch].
1911 * Implemented the KILL command to the client. Implemented the
1912 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1913 Affected files lib/silcclient/command[_reply].c and
1914 lib/silcclient/client_notify.c. Implemented the KILL notify
1915 printing in the user inteface.
1917 * Fixed a lot silc_parse_nick memory leaks from the client
1918 library in the file lib/silcclient/command.c.
1920 * Changed the silc_server_send_notify_on_channels's `sender'
1921 argument from SilcSocketConnection to SilcClientEntry to
1922 check the sender as entry and not as connection object and not
1923 to send to the client provided as argument. The affected file
1924 is silcd/packet_send.[ch].
1926 * The notify packets that are destined directly to the client used
1927 to not to be processed by the server. Now changed that and the
1928 server processes all notify packets. After relaying the packet
1929 to the client the notify packet is processed in the server.
1931 * The silc_server_free_client_data now checks whether there is
1932 pending outgoing traffic for the client and purges the data to
1933 the network before removing the client entry.
1935 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1938 an client is killed from the SILC Network. Updated the protocol
1941 Added new function silc_server_send_notify_killed to the
1942 silcd/packet_send.[ch].
1944 * Added function silc_server_packet_relay_notify to relay notify
1945 packets that are destined directly to a client. In this case
1946 the server does not process the notify packets but merely relays
1947 it to the client. Affected file silcd/packet_send.[ch].
1949 Added also silc_server_packet_process_relay_notify to check
1950 whereto relay the notify. Affected file is
1951 silcd/packet_receive.[ch].
1953 * Implemented the KILL command to the server.
1957 * Added the backup schema desgined last fall to the protocol
1958 specs for everyone to see. The specification is in the
1959 *-spec-xx.txt draft and the packet type definitions for the
1960 backup routers is in *-pp-xx.txt draft. Thusly, added also
1961 new packet type SILC_PACKET_CELL_ROUTERS.
1963 * A big security problem in the implementation discovered. The
1964 signoff of an client did not cause new channel key generation
1965 which it of course should've done. The channel keys must be
1966 always re-generated when client leaves (or signoffs) the channel.
1967 The silc_server_remove_from_channels funtion now handles
1968 the channel key re-generation.
1970 * Added `sender' argument to the silc_server_send_notify_on_channels
1971 to not to send the client provided as argument. Affected file
1972 silcd/packet_send.[ch].
1974 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Implemented OPER and SILCOPER commands into the server and
1979 * Added silc_auth_verify and silc_auth_verify_data to verify
1980 the authentication directly from the authentication payload.
1981 It supports verifying both passphrase and public key based
1982 authentication. Affected file lib/silccore/silcauth.[ch].
1984 * Added `hash' field to the SilcIDListData structure. It is the
1985 hash negotiated in the SKE protocol. Affected file is
1988 * Slight redesigning of the SilcAuthPayload handling routines.
1989 Do not send SilcPKCS but SilcPublicKey as argument.
1991 * Implemented the public key authentication support to the
1992 serverconfig. The public key is loaded from the provided path
1993 and saved as authentication data to void * pointer. Thus,
1994 changed the unsigned char *auth_data to void *auth_data;
1996 * Fixed SHUTDOWN command to send the reply before the server
1997 is shutdown. :) Affected file silcd/command.c.
1999 * Fixed fatal bug in CONNECT command. The hostname was invalid
2000 memory and server crashed. Affected file silcd/command.c.
2002 * Fixed fatal bug in CLOSE command. The server_entry became
2003 invalid but was referenced later in the command. Affected file
2006 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Fixed fatal bug in failure packet handling. Server ignored
2009 the failure and thus crashed when it came.
2013 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2016 that the command may be executed only once in (about) 2 seconds.
2017 The old SILC_CF_LAG flag is same but allows command bursts up
2018 to five before limiting.
2020 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2021 server code. Various commands now includes the CF_LAG_STRICT
2022 flag to disallow any kind of miss-use of the command.
2024 * Fixed the silc_buffer_unformat to not to allocate any data
2025 if the length of the data is zero. It used to allocate the
2026 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2028 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Changed the format of AdminConnection configuration section
2031 in the server. Added username of the admin to the format.
2032 Affected files silcd/serverconfig.[ch].
2034 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2035 to return admin configuration data by host, username and/or
2038 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Implemented WHOWAS command to the server. Added the functions:
2042 silc_server_command_whowas_parse,
2043 silc_server_command_whowas_send_reply,
2044 silc_server_command_whowas_from_client and
2045 silc_server_command_whowas_from_server
2047 * Added <Client ID> argument to the WHOWAS command reply. Updated
2048 the protocol specs accordingly.
2050 * Implemented WHOWAS command and command_reply to the client
2053 Implemented the WHOWAS printing on the user interface.
2055 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * Added new argument to the WHOWAS command reply, the real name.
2058 It is an optional argument. Updated the protocol specs.
2060 * Added SilcIDCacheDestructor callback that is registered when
2061 the SilcIDCache is allocated. The callback is called when
2062 an cache entry in the ID Cache expires, or is purged from the
2063 cache. Added into lib/silccore/idcache.[ch].
2065 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2066 to destruct the client entries when the cache entry expires.
2067 Other ID Cache's in server and in the client library ignores
2070 * If the ID Cache entry's `expire' field is zero then the entry
2071 never expires. Added boolean `expire' argument to the
2072 silc_idcache_add function in the lib/silccore/idcache.[ch].
2073 If it is TRUE the default expiry value is used.
2075 * Added silc_server_free_client_data_timeout that is registered
2076 when client disconnects. By default for 5 minutes we preserve
2077 the client entry for history - for WHOWAS command.
2079 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Added support to the server to enforce that commands are not
2082 executed more than once in 2 seconds. If server receives
2083 commands from client more frequently, timeout is registered
2084 to process the commands. Affected file silcd/command.c.
2085 Added new function silc_server_command_process_timeout.
2087 * Changed NICK_NOTIFY handling in client library to check that
2088 if the client's nickname was changed, so there is no need to
2089 resolve anything from the server.
2091 * Removed error printing from the WHOIS and IDENTIFY commands.
2092 If error occurs then it is ignored silently in the client library.
2093 The application, however, may map the received error to
2094 human readable error string. The application currently maps
2095 the NO_SUCH_NICKNAME error to string.
2097 * Made the command status message public to the application. Moved
2098 them from lib/silcclient/command_reply.c to
2099 lib/silcclient/command_reply.h. The application can map the
2100 received command status to the string with the
2101 silc_client_command_status_message function.
2103 * Added check to the server to check that client's ID is same
2104 as the Source ID in the packet the client sent. They must
2107 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Added dist-bzip hook to the Makefile.am to make bzip2
2110 compressed distributions.
2112 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2114 * Server now enforces the maximum length for the nickname and
2115 the channel as protocol specification dictates. 128 bytes for
2116 nickname and 256 bytes for channel name.
2118 * Moved the WHOIS printing to the application. The client libary
2119 does not print out the WHOIS information anymore, the application
2120 must do it. Renamed silc_client_command_reply_whois_print to
2121 the silc_client_command_reply_whois_save.
2123 The client's idle time is also sent to the application now, and
2124 the idle is shown on screen.
2126 * Added silc_client_command_reply_identify_save to save the
2127 received IDENTIFY entries.
2129 * Do not check for channel private keys in message sending and
2130 reception if the channel does not have the PRIVKEY mode set.
2131 Affected file lib/silclient/client_channel.c.
2133 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2136 just surfaced after chaning the JOIN procedure.
2138 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Added silc_client_get_clients_by_list to get client entries
2141 from Client ID list, that is returned for example by JOIN
2142 and USERS command replies. The application should use this
2143 function for example when JOIN command reply is received to
2144 resolve the clients already on the channel (library does not
2145 do that anymore as USERS command reply is not used in the JOIN
2146 procedure anymore). Affected files lib/silcclient/silcapi.h and
2147 lib/silcclient/idlist.c.
2149 * JOIN command reply and USERS command reply returns now SilcBuffer
2150 pointers instead of unsigned char pointers when returning
2151 the client list and mode list.
2153 * Added <Client ID> argument to the JOIN command reply, mainly
2154 for the server to identify for which client the command was
2155 originally sent. Updated protocol specs accordingly.
2157 * Added SilcDlist private_key pointer to the SilcChannelEntry
2158 in the client to support the channel private keys. Affected
2159 file is lib/silcclient/idlist.h.
2161 * Added SilcChannelPrivateKey argument to the function
2162 silc_client_send_channel_message so that application can choose
2163 to use specific private ke if it wants to. If it is not provided,
2164 the normal channel key is used, unless private keys are set.
2165 In this case the first (key that was added first) is used
2166 as the encryption key.
2168 * Implemented the support for channel private key handling.
2169 Implemented the following functions:
2171 silc_client_add_channel_private_key,
2172 silc_client_del_channel_private_keys,
2173 silc_client_del_channel_private_key,
2174 silc_client_list_channel_private_keys and
2175 silc_client_free_channel_private_keys
2177 Affected file lib/silcclient/client_channel.c.
2179 * Added the support for the private keys in the channel message
2180 sending and encryption and in the message reception and
2181 decryption. Affected funtions are
2182 silc_client_send_channel_message and silc_client_channel_message.
2184 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Added SKE's key verify callback to the client library's
2187 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2189 * Removed the statement that server (or router) must send USERS
2190 command reply when joining to the channel so that the client
2191 knows who are on the channel. Instead, the client list and
2192 client's mode list is now sent in the JOIN command reply to the
2193 client who joined channel. This is better solution.
2195 * Added function silc_server_get_users_on_channel and function
2196 silc_server_save_users_on_channel to the silcd/server.[ch].
2198 * Removed function silc_server_command_send_users from the
2201 * Do not show topic on the client library anymore. The topic is
2202 sent in the command reply notify to the application and the
2203 application must show the topic now.
2205 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Added client searching by nickname hash into the IDENTIFY and
2208 WHOIS commands in the server as they were clearly missing from
2209 them. Affected file is silcd/command.c.
2211 * Fixed a bug in private message receiving in the client library.
2212 The remote ID was freed and it wasn't supposed, now it is
2215 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Minor fix to the channel payload; allocate the data area, as it
2218 needs to be of specific length.
2220 * If the key agreement port is zero then the operating
2221 system will define the bound port. Affected files are
2222 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2224 * Added new function silc_channel_payload_decrypt into the file
2225 lib/silccore/silcchannel.[ch].
2227 * Moved the channel message etc, check from silc_packet_decrypt
2228 to applications. The library calls now a generic
2229 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2230 when the packet is either normal or special. This was done to
2231 allow more wide range of checking that was not allowed when
2232 the code was in library. Now applications can do virtually any
2233 checks to the packet and return to the library the decision how
2234 the packet should be processed. Affected files are
2235 lib/silccore/silcpacket.[ch].
2237 Added silc_server_packet_decrypt_check to the server and
2238 silc_client_packet_decrypt_check to the client library.
2240 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2241 to send with specified source and destination information.
2243 * Channel message delivery between routers was broken after the
2244 channel key distribution was fixed earlier. The channel key
2245 was used be to distributed to other routers as well which is not
2246 allowed by the protocol. Now this is fixed and channel keys
2247 really are cell specific and the channel message delivery between
2248 routers comply with the protocol specification.
2250 * Fixed various commands in server to check also the global list
2251 for the channel entry and not just the local list. The affected
2252 file silcd/command.c.
2254 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Added assert()s to buffer formatting and unformatting routines
2257 to assert (if --enable-debug) when error occurs. Affected
2258 file: lib/silcutil/silcbuffmt.c.
2260 * Changed to auto-reconnect to check whether the remote host is
2261 router and register the re-connect timeout if it is. It used
2262 to check that whether we are normal server, but router must do
2263 auto-reconnect with another router as well. Affected file
2266 * Removed the [<key len>] option from CMODE command as the cipher
2267 name decides the key length, nowadays. See the defined ciphers
2268 from the protocol specification.
2270 * Added [<hmac>] option to the CMODE command to define the HMAC
2271 for the channel. Added SILC_CMODE_HMAC channel mode.
2273 * Added [<hmac>] option for the JOIN command so that user can
2274 select which HMAC is used to compute the MACs of the channel
2277 * Added Hmac field to the Channel Message Payload. The integrity
2278 of plaintext channel messages are now protected by computing
2279 MAC of the message and attaching the MAC to the payload. The
2280 MAC is encrypted. Now, it is clear that this causes some
2281 overhead to the size of the packet but rationale for this is that
2282 now the receiver can verify whether the channel message decrypted
2283 correctly and also when private keys are set for the channel the
2284 receiver can decrypt the packet with several keys and check from
2285 the MAC which key decrypted the message correctly.
2287 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2288 lib/silccrypt/silccipher.[ch].
2290 * Added silc_hash_len to return the digest length into the
2291 lib/silcrypt/silchash.[ch].
2293 * Rewrote parts of Silc Channel Payload interface in the
2294 lib/silccore/silcchannel.[ch]. The encode function now also
2295 encrypts the packet and parse function decrypts it.
2297 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Fixed a minor formatting bug in the SKE's key material processing.
2300 It actually might have processed the keys wrong way resulting
2303 * Redefined the mandatory HMAC algorithms and added new algorithms.
2304 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2305 and hmac-md5 truncated to 96 bits. The mandatory is now
2306 hmac-sha1-96. Rest are optional (including the one that used
2307 to be mandatory). Rationale for this is that the truncated HMAC
2308 length is sufficient from security point of view and can actually
2309 make the attack against the HMAC harder. Also, the truncated
2310 HMAC causes less overhead to the packets. See the RFC2104 for
2313 * Added new [hmac] configuration section. The SKE used to use
2314 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2315 is of course wrong. The official names that must be proposed in
2316 the SKE are the ones defined in the protocol specification
2317 (hmac-sha1-96 for example). The user can configure any hmac
2318 using any hash function configured in the [hash] section. At
2319 least, the mandatory must be configured.
2321 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2323 * Added HMAC list to the SKE proposal list. It has now both
2324 hash algorithm list and HMAC list. This makes the protocol
2325 incompatible with previous versions. The SKE now seems to work
2326 the way it is supposed to work, for the first time actually.
2328 * Defined plain Hash algorithms to the protocol specification.
2331 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Implemented support for key agreement packets into the server.
2334 Added functions silc_server_key_agreement and
2335 silc_server_send_key_agreement. Other than these functions,
2336 server has nothing to do with this packet.
2338 * Added support for private message key packets into the server.
2339 Added functions silc_server_private_message_key and
2340 silc_server_send_private_message_key.
2344 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2345 called in the protocol's final callback instead in the END
2346 protocol state. This makes a little more sense and in the same
2347 time in client we can use the same protocol routines for normal
2348 key exchange and to key agreement packet handling as well.
2350 * Added to both client's and server's KE protocol context the
2351 SilcSKEKeyMaterial pointer to save the key material. We will
2352 bring the key material to the protocol's final callback by doing
2353 this. The final callback must free the key material.
2355 * Added SKE's packet_send callback into client's KE protocol
2356 context so that the caller can choose what packet sending function
2357 is used. This way we can use different packet sending when
2358 doing normal SKE when doing key agreement packet handling (in
2359 the key agreement packet handling we do not want to encrypt
2362 * Implemented the responder side of the key agreement routines
2363 in the client. The client can now bind to specified port and
2364 accept incoming key negotiation. The key material is passed
2365 to the application after the protocol is over.
2367 * Implemented the processing of incoming Key Agreement packet
2368 in the client. Added function silc_client_key_agreement to
2371 * Implemented the intiator side of the key agreement routines
2372 in the client. The client can now initiate key agreement with
2373 another remote client. The key material is passed to the
2374 application after the protocol is over.
2376 * Created client_keyagr.c to include all the key agreement
2379 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2380 SILC_TASK_CALLBACK except that it is not static.
2382 * Created client_notify.c and moved the Notify packet handling
2383 from the client.[ch] into that file.
2385 * Created client_prvmsg.c and moved all private message and
2386 private message key routines from the client.[ch] into that file.
2388 * Create client_channel.c and moved all channel message and
2389 channel private key routines from the client.[ch] into that file.
2391 * Changed silc_client_get_client_by_id_resolve to resolve with
2392 WHOIS command instead of IDENTIFY command, in the file
2393 lib/silclient/idlist.c.
2395 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Implemented the SKE's responder side to the Client library.
2399 * When FAILURE is received to the protocol do not trust it
2400 blindly. Register a timeout to wait whether the remote closes
2401 the connection as it should do it, only after that process the
2402 actual failure. This was changed to both client and server.
2404 * Added client_internal.h to include some of the structures
2405 there instead of client.h in lib/silcclient/.
2407 * Added function silc_task_unregister_by_callback to unregister
2408 timeouts by the callback function.
2410 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Some "Incomplete WHOIS info" errors has been appearing on the
2413 log files. Took away the entry->userinfo check from WHOIS
2414 reply sending. The entry->userinfo is now " " if client did not
2415 provide one. I thought this was fixed earlier but something
2416 is wrong still. Let's see if the error still appears.
2418 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * Fixed a minor bug in the login when the channel key is
2421 re-generated in the server. It used to generate the key in
2422 wrong order and thus caused problems in the channel traffic.
2424 * Fixed a minor bug in channel key distsribution after
2425 KICK command. The key was not sent to the router even though
2428 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Added silc_ske_process_key_material_data as generic routine
2431 to process any key material as the SILC protocol dictates. The
2432 function is used by the actual SKE library but can be used by
2433 applications as well. This relates to the private message keys
2434 and the channel private keys since they must be processed the
2435 same way the normal SILC session keys. The protocol dictates
2436 this. Affected files: lib/silcske/silcske.[ch].
2438 Added also silc_ske_free_key_material to free the
2439 SilcSKEKeyMaterial structure.
2441 * Defined silc_cipher_set_key function to set the key for
2442 cipher without using the object's method function. The affected
2443 files: lib/silccrypt/silccipher.[ch].
2445 * Implemented silc silc_client_add_private_message_key,
2446 silc_client_add_private_message_key_ske,
2447 silc_client_del_private_message_key,
2448 silc_client_list_private_message_keys and
2449 silc_client_free_private_message_keys functions in the
2452 Added functions silc_client_send_private_message_key to send
2453 the Private Message Key payload and silc_client_private_message_key
2454 to handle incoming Private Message Key payload.
2456 * Added Cipher field to the Private Message Key payload to set
2457 the cipher to be used. If ignored, the default cipher defined
2458 in the SILC protocol (aes-256-cbc) is used.
2460 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Removed lib/silcclient/ops.h file.
2464 Redefined parts of the SILC Client Library API. Created new
2465 file silcapi.h that deprecates the ops.h file and defines the
2466 published Client Library API. Defined also private message key
2467 API and channel private key API into the file.
2469 This is the file that the application must include from the
2470 SILC Client Library. Other files need not be included by
2471 the application anymore.
2473 * Added new key_agreement client operation callback and also
2474 defined the Key Agreement library API for the application.
2476 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2479 is used by clients to request key negotiation between another
2480 client in the SILC network. If the negotiation is started it
2481 is performed using the SKE protocol. The result of the
2482 negotiation, the secret key material, can be used for example
2483 as private message key.
2485 Implemented the Key Agreement payload into the files
2486 lib/silccore/silauth.[ch].
2488 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Redefined ciphers for the SILC protocol. Added some new ciphers
2491 and defined the key lengths for the algorithms. Changed the
2492 code accordingly. The default key length is now 256 bits.
2494 * Fixed SKE key distribution function silc_ske_process_key_material
2495 when the key length is more than 128 bits. The default key
2496 length in SILC is now 256 bits.
2498 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2499 to indicate unsupported algorithm.
2501 * Renamed rijndael.c to aes.c and all functions as well.
2503 * Fixed a long standing channel key setting bug in client library.
2504 Weird that it has never surfaced before.
2506 * Fixed bug in channel deletion. If the entire channel is removed
2507 then it must also delete the references of the channel entry
2508 from the client's channel list as the client's channel entry and
2509 the channel's client entry share same memory.
2511 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Implemented CONNECT and SHUTDOWN commands in the client.
2515 * Implemented CLOSE command to the client.
2517 * Added the function silc_idlist_find_server_by_name into the
2518 files silcd/idlist.[ch].
2520 Added the function silc_idlist_find_server_by_conn into the
2521 files silcd/idlist.[ch].
2523 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * DIE command was renamed to SHUTDOWN. Updated the both code
2528 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2529 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2531 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2534 * Added function silc_server_create_connection function to create
2535 connection to remote router. My server implementation actually
2536 does not allow router to connect to normal server (it expects
2537 that normal server always initiates the connection to the router)
2538 so the CONNECT command is only good for connecting to another
2541 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2544 or some other client was kicked from the channel.
2546 Implemented the handling of the notify type to both client
2549 Implemented silc_server_send_notify_kicked to send the KICKED
2550 notify. It is used to send it to the server's primary router.
2552 * Implemented the KICK command into server and client.
2554 * Added `query' argument to the silc_idlist_get_client function
2555 to indicate whether to query the client from server or not if
2558 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2559 to indicate that the client is not channel founder.
2563 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2565 * Removed the rng context from SilcPacketContext structure and
2566 changed that the packet routine uses the Global RNG API.
2568 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Added support for quit message that client can "leave" on the
2571 channel when it quits the SILC. It is ditributed inside the
2572 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2574 Added silc_server_free_client_data that will take the
2575 signoff message as argument.
2577 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2579 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Updated parts of the protocol specification to keep it up
2584 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2587 payloads in one packet.
2589 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2590 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2591 use now the new List flag.
2593 * Also deprecated the following packet types: REPLACE_ID,
2594 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2596 * Added list support for Notify packet in server.
2598 * Added silc_server_send_notify_channel_change to send the
2599 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2600 the silc_server_send_replace_id.
2602 * Added silc_server_send_notify_nick_change to send the
2603 NICK_CHANGE notify type. Deprecates the function
2604 silc_server_send_replace_id.
2606 * Added silc_server_send_notify_join to send the JOIN notify type.
2607 Deprecates the function silc_server_send_new_channel_user.
2609 * Added silc_server_send_notify_leave to send LEAVE notify type.
2610 Deprecates the function silc_server_send_remove_channel_user.
2612 * Added silc_server_send_notify_cmode and
2613 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2614 types. Deprecates the silc_server_send_set_mode function.
2616 * Added SERVER_SIGNOFF notify type to indicate that server has
2617 quit. This means that all clients on the channel from that
2618 server will drop. This can be also used when netsplit happens.
2620 Deprecated REMOVE_ID packet type since it is not needed anymore
2623 Added silc_server_send_notify_server_signoff to send the
2624 SERVER_SIGNOFF notify type. Deprecates the function
2625 silc_server_send_remove_id.
2627 Added also silc_server_send_notify_signoff to send the
2628 SIGNOFF notify type.
2630 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2631 SILC protocol from this day on. Changed the protocol
2632 specification as well.
2634 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2635 notify type. It is used between routers to notify about
2636 topic changes on a channel.
2638 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2641 * Partly updated the protocol specification to comply with the
2642 changes now made. It is still though a bit outdated.
2644 * The JOIN notify type now takes one extra argument <Channel ID>.
2645 The packet used to be destined to the channel but now the
2646 JOIN type may be sent as list thus it is impossible to
2647 destine it to any specific channel. By adding this argument
2648 it is again possible.
2650 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added CREDITS file. The CHANGES and CREDITS file will appear
2653 in the distribution as well.
2655 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2658 types in the server's silcd/packet_receive.c.
2660 * Implemented CMODE and CUMODE to work in router environment.
2662 * Fixed minor encoding and decoding buglet from the
2663 lib/silccore/silcmode.c.
2665 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2668 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2670 * Changed all SilcConfigServer* and silc_config_server* to
2671 SilcServerConfig* and silc_server_config*, respectively.
2674 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * Associated the ID (client or server ID) to the Authentication
2677 Payload to avoid any possibility of forging. Updated the
2678 protocol specification and the code accordingly.
2680 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * The RSA key length is now save to the RsaKey context in the
2683 key generation process in lib/silccrypt/rsa.c. The key length
2684 is now used to figure out the maximum size of the block allowed
2685 to be encrypted/signed.
2687 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2688 is equivalent to the silc_mp_mp2bin but does not allocate any
2691 * Changed silc_mp_mp2bin API to take length argument. If it is
2692 non-zero then the buffer is allocated that large. If zero, then
2693 the size is approximated using silc_mp_sizeinbase, which however
2696 * Created Global RNG API which is global RNG that application can
2697 initialize. After initializing, any routine anywhere in the
2698 code (including library) can use RNG without allocating a new
2699 RNG object. This was done to allow this sort of use of the
2700 RNG in code that has no chance to allocate RNG object. All
2701 applications currently allocate this and many routines in the
2702 library use this. Affected file lib/silccrypt/silcrng.[ch].
2704 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2705 it to use the Global RNG API.
2707 * Defined Authentication Payload into protocol specification that
2708 is used during SILC session to authenticate entities. It is
2709 used for example by client to authenticate itself to the server
2710 to obtain server operator privileges.
2712 Implemented this payload into the lib/silccore/silcauth.[ch].
2713 Implemented also routines for public key based authentication
2714 as the new protocol specification dictates.
2716 Moved definitions of different authentication methods from
2717 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2719 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2720 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2721 silc_pkcs_verify_with_hash functions into the file
2722 lib/silccrypt/silcpkcs.[ch].
2724 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * The client entry's userinfo pointer must be always valid.
2727 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2728 will fail since it requires the userinfo. Now, the userinfo
2729 is allocated as "" if actual userinfo does not exist. Actually,
2730 it must exist and it is totally Ok to drop client connections
2731 that does not announce the userinfo. However, we will make
2732 this workaround for now.
2734 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2735 to return the remote port by socket.
2737 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2740 SILC_SERVER_PENDING_EXEC and added an new macro
2741 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2742 data or when error occurs while processing the pending command.
2744 Added new argument `destructor' into silc_server_command_pending
2745 and to the SilcServerCommandPending object. This destructor is
2746 now called after calling the pending callback or if error occurs
2747 immediately. If error occurs the actual pending callback won't
2748 be called at all - only the destructor. The destructor may be
2749 NULL if destructor is not needed.
2751 All this applies for client library code as well. Similar
2752 changes were made there as well for the pending commands.
2754 In the client, the application must now allocate the
2755 SilcClientCommandContext with the silc_client_command_alloc
2758 * Added reference counter to the SilcServerCommandContext. Added
2759 function silc_server_command_alloc and silc_server_command_dup
2762 Same type of functions added to the client library for the same
2765 * Removed the cmd_ident from IDListData away since it is now
2766 global for all connections. It is the command identifier used
2767 in command sending and with pending commands. The affected file
2770 * Added reference counter to the SilcSocketConnection objecet to
2771 indicate the usage count of the object. The object won't be
2772 freed untill the reference counter hits zero. Currently only
2773 server uses this, and client ignores it. The client must be
2774 set to use this too later. The affected files are
2775 lib/silccore/silcsockconn.[ch]. Added also the function
2776 silc_socket_dup to increase the reference counter.
2778 This was mainly added because it is possible that the socket
2779 is removed underneath of pending command or other async
2780 operation. Now it won't be free'd and proper DISCONNECTING
2781 flags, etc. can be set to avoid sending data to connection that
2782 is not valid anymore.
2784 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2785 the connection. After that it sets SILC_SET_DISCONNECTED.
2786 It is, however, possible that the socket data is not still freed.
2787 The silc_server_packet_process now checks that data is not
2788 read or written to connection that is DISCONNECTED. The socket
2789 get's freed when the reference counter hits zero.
2791 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Changed the client operation API: channel_message operation's
2794 `sender' is now the client entry of the sender, not the nickname
2795 and the `channel' is the channel entry, not the channel name.
2797 In the private_message operation the `sender' is now also the
2798 client entry of the sender not the nickname.
2800 Affected file is lib/silcclient/ops.h and all applications
2801 using the client operations.
2803 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Moved the calling of ops->connect() from connect_to_server_final
2806 into receive_new_id functin since that is the point when the
2807 client is actually allowed to send traffic to network. The
2808 affected file is lib/silcclient/client.c.
2810 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2813 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2814 (if needs broadcasting) instead of broadcasting the packets one
2815 by one which would make a burst in the network traffic.
2817 * Added `broadcast' argument to the functions in silcd/server.[ch]
2818 silc_server_create_new_channel[_with_id] to indicate whether
2819 to send New Channel packet to primary router.
2821 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Added new function into the silcd/server.[ch] files:
2824 silc_server_create_new_channel_with_id to create new channel with
2825 already existing Channel ID.
2827 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2828 lib/silccore/silcpacket.h. This packet is used t send list of
2829 Set Mode payloads inside one packet. Server uses this to set
2830 the modes for the channels and clients on those channels, that it
2831 announced to the router when it connected to it. The protocol
2832 specification has been updated accordingly.
2834 * The silc_server_new_channel did not handle the packet coming
2835 from normal server as it normally does not send that. However,
2836 when it announces its channels it does send it. Implemented
2837 the support for that.
2839 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2840 into the file lib/silccore/id.h.
2842 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Fixed memory leaks in the functions silc_idlist_del_client,
2845 silc_idlist_del_channel and silc_idlist_del_server in the file
2846 silcd/idlist.c. All of those leaked like a sieve.
2848 * Fixed some small memory leaks in the client's function
2849 silc_client_notify_by_server.
2851 * Added functions into silcd/server.c: silc_server_announce_clients,
2852 silc_server_announce_channels and silc_server_announce_server.
2853 These functions are used by normal and router server to announce
2854 to its primary router about clients, channels and servers (when
2855 router) that we own. This is done after we've connected to the
2858 These functions effectively implements the following packet types:
2859 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2860 and SILC_PACKET_NEW_ID_LIST.
2862 * Added new functions into the silcd/packet_receive.[ch]:
2863 silc_server_new_id_list, silc_server_new_channel_list and
2864 silc_server_new_channel_user_list to handle the incoming
2865 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2867 * Added support of changing Channel ID in the function
2868 silc_server_replace_id. If the server that announces a channel
2869 to the router already exists in the router (with same name but
2870 with different Channel ID), router is responsible to send
2871 Replace ID packet to the server and force the server to change
2872 the Channel ID to the one router has.
2874 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2875 client that the Channel ID has been changed by the router. The
2876 normal server sends this to the client. Client must start using
2877 the new Channel ID as the channel's ID.
2879 Implemented handling of this new type into lib/silcclient/client.c
2880 into the function silc_client_notify_by_server.
2882 * Added new function silc_idlist_replace_channel_id into the files
2883 silcd/idlist.[ch] to replace the Channel ID.
2885 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Call silc_server_command_identify_check always when processing
2888 the IDENTIFY command in silcd/command.c
2890 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2893 send keepalive packets. The packet can be sent by clients,
2894 servers and routers.
2896 Added function silc_socket_set_heartbeat into the file
2897 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2898 If not set, the heartbeat is not performed. The actual
2899 heartbeat is implemented in the low level socket connection
2900 library. However, application is responsible of actually
2903 Added silc_server_send_heartbeat to send the actual heartbeat
2904 packet into silcd/packet_send.[ch]. Server now performs
2905 keepalive with all connections.
2907 * Added silc_task_get_first function into lib/silcutil/silctask.c
2908 to return the timeout task with shortest timeout. There was a bug
2909 in task unregistration that caused problems. TODO has been
2910 updated to include that task system must be rewritten.
2912 * The client library will now resolve the client information when
2913 receiving JOIN notify from server for client that we know but
2914 have incomplete information.
2916 * Rewrote parts of silc_server_remove_from_channels and
2917 silc_server_remove_from_one_channel as they did not remove the
2918 channel in some circumstances even though they should've.
2920 * Encryption problem encountered in server:
2922 The LEAVE command used to send the Channel Key packet to the
2923 router immediately after generating it. However, the code
2924 had earlier sent Remove Channel user packet but not immediately,
2925 ie. it was put to queue. The order of packets in the router
2926 was that Channel Key packet was first and Remove Channel User
2927 packet was second, even though they were encrypted in the
2928 reverse order. For this reason, MAC check failed. Now, this
2929 is fixed by not sending the Channel Key packet immediately but
2930 putting it to queue. However, this is more fundamental problem:
2931 packets that are in queue should actually not be encrypted
2932 because packets that are sent immediately gets encrypted
2933 actually with wrong IV (and thus MAC check fails). So, packets
2934 that are in queue should be encrypted when they are sent to
2935 the wire and not when they put to the queue.
2937 However, the problem is that the current system has not been
2938 designed to work that way. Instead, the packet is encrypted
2939 as soon as possible and left to the queue. The queue is then
2940 just purged into wire. There won't be any fixes for this
2941 any time soon. So, the current semantic for packet sending
2944 o If you send packet to remote host and do not force the send
2945 (the packet will be in queue) then all subsequent packets to the
2946 same remote host must also be put to the queue. Only after the
2947 queue has been purged is it safe again to force the packet
2950 o If you send all packets immediately then it safe to send
2951 any of subsequent packets through the queue, however, after
2952 the first packet is put to queue then any subsequent packets
2953 must also be put to the queue.
2955 Follow these rules and everything works fine.
2957 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added new function silc_server_remove_clients_by_server to
2960 remove all client entries from ID list when the server connection
2961 is lost. In this case it is also important to invalidate all
2962 client entires as they hold the invalid server entry. This
2963 fixes fatal bug when server has lost connection and will reconnect
2966 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Made some sanity checks to silc_server_daemonise like to check
2969 whether the requested user and group actually exists.
2971 * Added sanity check to SKE's silc_ske_responder_finish to check
2972 that the public and private key actually is valid.
2974 * Invalidate the client's nickname when receiving Replace ID
2975 packet and the Client ID is being replaced. This means that the
2976 server will query the nickname if someone needs it (client)
2979 * Sort the ID Cache in client library when the ID Cache data
2980 has changed (needs sorting).
2982 * Do not allow for SILC client to create several connections to
2983 several servers. The client does not support windows right now
2984 and generating multiple connections causes weird behaviour.
2986 Irssi-silc client does support windows and can handle several
2987 connections without problems, see: www.irssi.org and SILC plugin.
2989 * Fixed some places where client was added to the IDList. The
2990 rule of thumb is following (in order to get everything right):
2991 If the client is directly connected local client then the
2992 `connection' argument must be set and `router' argument must be
2993 NULL to silc_idlist_add_client function. If the client is not
2994 directly connected client then the `router' argument must
2995 bet set and the `connection' argument must be NULL to the
2996 silc_idlist_add_client function.
2998 * The funtion silc_server_packet_send_local_channel actually did
2999 not check whether the client was locally connected or not. It
3000 does that now. Fixed a bug related to LEAVE command.
3002 * Fixed Remove Channel User payload parsing bug in server's
3003 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3005 * The server's silc_server_save_channel_key now checks also the
3006 global ID list for the channel as it might not be in the local
3007 list. Fixed a bug related to LEAVE command.
3009 * Is this the end of the [<unknown>] buglet that has been lurking
3010 around for a long time? A little for loop fix in server's
3011 silc_server_command_whois_parse that is used by both IDENTIFY
3012 and WHOIS command. At least, this was a clear bug and a cause
3013 of one type of [<unknown>] buglet.
3015 * WHOIS and IDENTIFY commands call the function
3016 silc_server_command_[whois/identify]_check function even if
3017 we are not router server.
3019 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Added --with-gmp configuration option. If set the GMP
3022 is always compiled in the SILC source tree. If not set then
3023 it is checked whether the system has the GMP3 installed. If
3024 it has then the GMP won't be compiled (the system's headers
3025 and library is used), if it doesn't have it then the GMP is
3026 compiled in the SILC source tree.
3028 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Changed RSA private exponent generation to what PKCS #1
3031 suggests. We try to find the smallest possible d by doing
3032 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3033 not security fix but optimization.
3035 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Added new config entry [Identity] to fork the server and run
3038 it as specific user and group. A patch from Bostik.
3040 * Imported Dotconf configuration library into lib/dotconf.
3041 This will be used to create the SILC configuration files later.
3042 It will appear in the distsribution after this commit.
3044 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * A big code auditing weekend happening. Auditing code for
3047 obvious mistakes, bugs and errors. Also, removing any code
3050 Removed files for being obsolete:
3052 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3053 inline in the file lib/silcutil/silcbuffer.h)
3055 o lib/silcutil/silcbufutil.c (the header has inline versions)
3057 Changed code to fix possible error conditions:
3059 o The buffer formatting routines now check that the destination
3060 buffer really has enough space to add the data. This applies for
3061 both buffer formatting and unformatting
3062 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3063 unformatting was changed to accomodate following rules:
3064 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3065 sent to the function while XXX_*STRING will not allocate or copy
3066 the data into the buffer. Instead it sets the pointer from the
3067 buffer into the pointer sent as argument (XXX_*STRING used to
3068 require that the pointer must be allocated already). This change
3069 makes this whole thing a bit more consistent and more optimized
3070 (note that the data returned in the unformatting with XXX_*STRING
3071 must not be freed now). The routines return now -1 on error.
3073 o Tried to find all code that use buffer_format and buffer_unformat
3074 and added return value checking to prevent formatting and
3075 especially unformatting errors and possible subsequent fatal
3078 o Changed ske->x and ske->KEY to mallocated pointers in
3079 lib/silcske/silcske.h. Fixed possible data and memory leak.
3081 o Added return value checking to all *_parse* functions. Fixed
3082 many memory leaks as well.
3084 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3085 so that buffer overflows would not happen. All code now also
3086 checks the return value as it can fail.
3088 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Added reconnection support to server if the normal server looses
3091 its connection to the router (for example if router is rebooted).
3092 The server performs normal reconnection strategy implemented
3093 to the server. Affected file silcd/server.c.
3095 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Added new packet type SILC_PACKET_SET_MODE that is used to
3098 distribute the information about changed modes (for clients,
3099 channels and clients channel modes) to all routers in the
3100 network. Updated the protocol specification accordingly.
3102 Added functions into silcd/packet_send.c and
3103 silcd/packet_receive.c: silc_server_send_set_mode,
3104 silc_server_set_mode.
3106 Added new files silcmode.[ch] into lib/silccore that implements
3107 the encoding and decoding of Set Mode Payload. Added new type
3108 SilcSetModePayload. Moved the definitions of different modes
3109 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3111 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Oops, a little mistake in server's connection authentication
3114 protocol. The protocol is not ended with FAILURE but with
3115 SUCCESS if the authentication is Ok. :) Affected file is
3118 * Implemented NICK_CHANGE notify handling in server in the file
3119 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3120 the local clients on the channel. After the changing nickname
3121 in router environment snhould work and the [<unknown>] nickname
3122 should appear no more.
3124 The silc_server_replace_id function that receives the Replace ID
3125 payload now sends the NICK_CHANGE notify type also in the file
3126 silcd/packet_receive.c
3128 * Changed WHOIS and IDENTIFY command to support the maximum amount
3129 of arguments defined in protocol specs (3328 arguments). This
3130 fixed a bug that caused problems when there were more than three
3133 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Added extra parameter, command identifier, to the
3136 silc_client_send_command so that explicit command identifier
3139 Changed that ID list routines uses specific command identifier
3140 when sending WHOIS/IDENTIFY requests to the server so that they
3141 can be identified when the reply comes back.
3143 Affected files lib/silcclient/command.[ch],
3144 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3146 * Added `sender' argument to silc_server_packet_send_to_channel
3147 to indicaet the sender who originally sent the packet to us
3148 that we are now re-sending. Ignored if NULL. Affected file
3149 silcd/packet_send.[ch].
3151 * Added some server statistics support in silcd/server_internal.h
3152 SilcServerStatistics structure and around the server code. Also
3153 send some nice statistics information when client is connecting
3156 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Fixed channel ID decoding in server's JOIN command reply in
3159 silcd/command_reply.c
3161 * Fixed braodcasting of replace ID payload to not to send it if
3162 we are standalone server in silcd/packet_receive.c.
3164 * Fixed all channel message sending routines to not to send
3165 packets to clients that has router set, since they are routed
3166 separately in the same function earlier. Affects file
3167 silcd/packet_send.c and all channel packet sending functions.
3169 * In USERS reply, res_argv[i] are not allocated, the table
3170 is allocated. Thus changed that free the table, not its
3173 * In server's whois_check and identify_check if the client is
3174 locally connected do not send any WHOIS commands - they are not
3177 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Fixed some minor bugs in client when sending WHOIS command. The
3180 arguments was in wrong order.
3182 * Removed statis function add_to_channel from server in
3183 silcd/command.c that was previously used with the joining but
3186 * Tested USERS command in router environment successfully with two
3187 routers, two servers and two clients.
3189 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3191 * Reorganized the USERS command and command reply in client library
3192 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3193 When the command is given by user we register a pending command
3194 callback that will reprocess the command after the reply has been
3195 received from the server. When reprocessing the packet we then
3196 display the information. Thus, the USERS information is displayed
3197 now in the command callback instead of in the command reply
3198 callback. The processing of the command is same as previously
3199 when server has sent the command reply in the JOINing process.
3201 * Added to USERS command in silcd/command_reply.c to join the client,
3202 we didn't use to know about, to the channel after we've created
3203 a client entry for it. Also, for clienet we did know already still
3204 check whether it is on the channel or not and add it if not.
3206 * Removed silc_server_command_join_notify as the function and its
3209 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Changed the client's pending command handling to the same as the
3212 server's pending command handling. It is also now possible to
3213 execute command reply functions from other command reply
3214 function as the function callbacks for commands and command
3215 replies are one and same. The pending commands are not static
3216 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3217 in client connection context. Thus, pending commands are server
3218 connection specific as it is convenient.
3220 Changed the function silc_client_command_pending and
3221 silc_client_command_pending_del and added new function
3222 silc_client_command_pending_check. Removed the
3223 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3226 * Added cmd_ident, current command identifier, to the client
3227 connection context in lib/silcclient/client.h to keep track on
3228 command identifiers used in command sending. Client's command reply
3229 function handling now supports the mandatory command identifiers.
3231 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3232 funtions in client to fully support pending command callbacks.
3234 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3235 as one of the arguments to the application in the command reply
3238 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3239 before first releasing SILC but came back. Now it is removed again
3240 and should come back nomore. The FORWARDED flag was used only
3241 by the JOINing procedure by forwarding the command packet to router.
3242 Now, the JOINing procedure has been changed to more generic (due
3243 to various router environment issues) and FORWARDED is not needed
3244 anymore for anything. The protocol specification is yet to be
3247 Now, removed silc_server_packet_forward from server and the flag
3248 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3250 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Renamed NAMES command to USERS command. The NAMES was named that
3253 due to historical reasons. Now it is renamed. Also, rewrote
3254 parts of the USERS command. The nickname list is not sent anymore
3255 by the server. Only Client ID and mode lists are sent in the USERS
3256 command. Changed this also to the protocol specification.
3258 The client now resolves the names and stuff after it receives
3259 the USERS list from the server when joining to the channel.
3261 * WHOIS and IDENTIFY commands has been changed to support multiple
3262 Client ID's per command. One can now search for multiple users
3263 in the network by sending only one WHOIS or IDENTIFY command.
3264 Changed the code and the protocol specifications.
3266 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3267 uses silc_server_command_whois_parse to parse the request. */
3269 * If normal server, do not parse the WHOIS and IDENTIFY requests
3270 before sending it to the router. Saves some time.
3272 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Fixed JOIN command on client library. Wrong number of arguments
3275 used to crash the client.
3277 * Added silc_server_channel_has_global function to check whether
3278 channel has global users or not.
3280 * Added silc_server_channel_has_local function to check whether channel
3281 has locally connected clients on the channel.
3283 * The silc_server_remove_from_one_channel now checks whether the
3284 channel has global users or not after given client was removed from
3285 the channel. It also checks whether the channel has local clients
3286 on the channel anymore. If it does not have then the channel entry
3287 is removed as it is not needed anymore.
3289 * The silc_server_notify now checks on JOIN notify whether the joining
3290 client is one of locally connected or global. If it is global then
3291 the channel has now global users on the channel and that is marked
3292 to the channel entry. Also, it now saves the global client to
3293 global list who is joining and JOINs it to the channel. This is
3294 for normal server, that is.
3296 Changed silc_server_send_notify_on_channel,
3297 silc_server_packet_relay_to_channel and
3298 silc_server_packet_send_to_channel check if we are normal server
3299 and client has router set (ie. global client) do not send the
3300 message to that client, as it is already routed to our router.
3302 * Implemented LEAVE notify type handling in silc_server_notify
3305 * Tested LEAVE command in router environment successfully. Tested
3306 with two routers, two servers and two clients.
3310 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3312 * Implemented SIGNOFF notify type handling in silc_server_notify
3315 * silc_server_remove_id now removes the client entry from all channels
3316 it has joined and thusly sends SIGNOFF notify type.
3318 * Rewrote the NAMES list generation in server by removing two excess
3319 loops. The lists are created now inside one loop.
3321 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * silc_server_remove_channel_user checks now also global list
3324 for channel and client.
3326 * silc_server_new_channel_user checks now both local and global
3327 list for channel and client. Fixed a bug in client id decoding.
3328 Used to decode wrong buffer.
3330 * silc_server_channel_message checks now both local and global
3331 list for channel entry.
3333 * Tested channel joining (hence JOIN) in router environment
3334 successfully. Tested with two routers, two servers and two
3337 * Tested channel message sending in router environment successfully.
3339 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Added silc_server_save_channel_key into server.[ch] to save the
3342 received channel key in Channel Key payload processing. It is
3343 also used in JOIN command reply handling.
3345 Equivalent function silc_client_save_channel_key added into
3346 client.[ch] into client library.
3348 * Changed JOIN command reply to send information whether the channel
3349 was created or not (is existing already) and the channel key
3350 payload. Changed protocol specs accordingly.
3352 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3353 the request was sent by ID and not by nickname. Crashed on
3356 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3359 now correctly save the received data.
3361 * silc_server_free_sock_user_data now notifies routers in the
3362 network about entities leaving the network.
3364 At the same time implemented functions silc_server_remove_id
3365 and silc_server_send_remove_id to receive and send REMOVE_ID
3366 packets. The packet is used to notify routers in the network
3367 about leaving entities. The ID removed will become invalid in
3370 * Added function silc_idlist_del_server into server. Removes and
3371 free's server entry from ID list.
3373 * silc_server_private_message function now checks, if we are router,
3374 that the destination ID really is valid ID, naturally.
3376 * In router when NEW_ID packet is received (for new client) the
3377 hash of the Client ID is saved in the ID Cache but the
3378 client->nickname is set to NULL, instead of putting the hash
3381 IDENTIFY command now also checks that client->nickname must be
3382 valid. If it is not if will request the data from the server who
3383 owns the client. Added new function
3384 silc_server_command_identify_check.
3386 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3387 to set the command to already allocated Command Payload.
3389 * Tested private message sending in router environment with two
3390 routers, two servers and two clients. Fixed minor bugs and now
3393 * Fixed segfault from client's NAMES command. Used to crash if
3396 * Forwarded packets must not be routed even if it is not destined
3397 to the receiver. Changed server code comply with this.
3399 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Added `require_reverse_mapping' boolean value to ServerParams
3402 structure. If TRUE (not default) the server will require that
3403 the connecting host has fully qualified domain name.
3405 If the reverse mapping is not required and hostname could not be
3406 found the IP address is used as hostname.
3408 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Implemented version string checking to both client and server.
3411 The check is incomplete currently due to the abnormal version
3412 strings used in development version of SILC.
3414 * Changed all command functions in server to use the new
3417 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Changed char *data to unsigned char *data in ID Cache system to
3420 support binary data as ID Cache data. Changed code to support
3421 binary data in lib/silccore/idcache.c.
3423 * Renamed silc_server_packet_relay_command_reply to
3424 silc_server_command_reply as it is normal packet receiving
3425 function. Rewrote the function to accept command replys for
3426 servers and not only for clients.
3428 * Mark remote router always as registered server if we are connecting
3429 to it. Otherwise, commands sent by the router to us are ignored.
3431 * All ID List find routines now returns the ID Cache Entry pointer
3432 as well if requested.
3434 * WHOIS command works now in router environment, tested with two
3435 routers, two servers and two clients.
3437 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3438 in router environment (as it is almost equivalent to WHOIS) but
3439 hasn't been tested thoroughly. Added new functions:
3441 silc_server_command_identify_parse
3442 silc_server_command_identify_send_reply
3443 silc_server_command_identify_from_client
3444 silc_server_command_identify_from_server
3446 * Disabled route cache adding because adding two different ID's with
3447 same IP replaces the old cache entry thus giving wrong route.
3448 The entry->router->connection is always the fastest route anyway
3449 so route cache may not be needed. Of course, new routes maybe
3450 established after receiving the ID when the entry->router->connection
3451 might not be anymore the most optimal.
3453 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Add route cache for received ID for fast routing.
3457 * Added silc_server_packet_route to route received packet on router
3458 that is not destined to us.
3460 * Renamed silc_server_get_route to silc_server_route_get.
3462 * Added id_string and id_string_len fields into SilcServer to
3463 include encoded ServerID for fast comparing without excess
3464 encoding of the ID's.
3466 * Cleaned up WHOIS command on server side. Added following static
3469 silc_server_command_whois_parse
3470 silc_server_command_whois_check
3471 silc_server_command_whois_send_reply
3472 silc_server_command_whois_from_client
3473 silc_server_command_whois_from_server
3475 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3476 arguments in command replies. All command functions should be
3477 updated to use this macro.
3479 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Minor typo fixes on command reply handling on server.
3483 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added silc_server_command_add_to_channel internal routine to add
3486 the client to the channel after router has created the channel and
3487 sent command reply to the server.
3489 * Added generic silc_server_send_command to send any command from
3492 * Use static buffer with ID rendering instead of duplicating data.
3494 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Fixed a channel user mode bug when joining to a channel server gave
3497 everybody channel founder rights, oops.
3499 * We mark ourselves as the router of the incoming server connection
3500 if we are router ourselves. This way we can check in some packet
3501 sending functions whether it is locally connected server. For
3502 incoming router connections we put NULL.
3504 * For router sending packets locally means now always sending the
3505 packet cell wide; to local clients and local servers. For normal
3506 server sending packet locally means sending it to only local
3509 * Fixed the JOIN command to really work in router environment. If the
3510 channel is created it is always created by the router. Router is
3511 also responsible of making the initial joining to the channel,
3512 sending JOIN notify to the sending server and distributing
3513 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3514 does not exist server doesn't do anything else but forward the
3515 command to the router which performs everything.
3517 * Added silc_server_send_channel_key function to send the Channel Key
3520 * Added silc_server_create_channel_key to create new channel key. The
3521 channel key is now re-generated everytime someone joins or leaves
3522 a channel, as protocol dictates. Note: channel->key_len is the
3525 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3528 packet_receive.[ch] to separate packet sending and receiving
3529 routines. The server.[ch] now includes everything else including
3530 actual packet processing (writing and reading data) and other
3533 Renamed silc_server_private_message_send_internal to
3534 silc_server_send_private_message. The routine is still though
3535 used only to relay private messages as server does not send
3536 private messages itself.
3538 Renamed silc_server_new_channel to silc_server_create_new_channel
3539 and added new function sicl_server_new_channel that handles the
3540 incoming New Channel packet. Added also new sending function
3541 silc_server_send_new_channel to send New Channel Payload.
3543 * Added new function silc_server_notify to process incoming notify
3544 packet to the server/router. Server may then relay the notify
3545 to clients if needed.
3547 * Added new function silc_server_new_channel_user to process incoming
3548 New Channel User packet. Router will redistribute the packet and
3549 send JOIN notify to its local clients and locally connected servers
3550 if needed. Normal server will send JOIN notify to its local client
3551 on same channel when received this packet. Added also corresponding
3552 sending function silc_server_send_new_channel_user to sent the
3555 * Added boolean route argument to send_notif_to_channel and
3556 packet_send_to_channel functions to attempt to route the packet
3557 if it is TRUE and send only locally if it is FALSE.
3559 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * silc_server_replace_id now broadcasts the received replace ID
3562 packet if it is not broadcast packet already. The router must
3563 broadcast to inform other routers about changed ID.
3565 * Added backpointer to server's router into SilcServer context in
3566 silcd/server_internal.h.
3568 * Fixed silc_server_packet_broadcast to send correct broadcast
3571 * The channel key is now distributed to the local client as soon
3572 as it is received from the router (in router environment) so that
3573 no other packet may be sent for the channel until client has
3576 * silc_server_remove_channel_user now broadcasts the received
3577 Remove Channel User packet if it is not broadcast packet already.
3578 The router must broadcast to inform other routers about removed
3581 * Added users field into SilcPacketContext that is a reference count
3582 of the context. One can increase the reference count by calling
3583 silc_packet_context_dup which is now changed to just increase the
3584 reference count instead of duplicating the data. The reference
3585 count is decresed by calling silc_packet_context_free that will
3586 free the data after the reference count hits zero.
3588 For now on the packet context and everything allocated into it
3589 (including the raw packet from network) must be freed by calling
3590 the new silc_packet_context_free function. Added also new function
3591 silc_packet_context_alloc that must be used now to allocate the
3592 context. This also means that if a routine is asynchronous from
3593 silc_[client/server]_packet_parse_type the packet context must
3594 be duplicated by calling silc_packet_context_dup. Otherwise it
3595 gets free'd after silc_[client/server]_packet_parse_type returns.
3596 Also, one must remember that if packet is duplicated then its
3597 reference count must be decresed by calling the free function as
3598 many times as it was duplicated.
3600 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3601 from both client and server.
3603 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Made joining to a channel working in router environment.
3607 * Cleaned up JOIN command on server side and create function
3608 silc_server_command_join_channel internal routine to make the
3611 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Changed silc_command_pending list to SilcDList. Also, added
3614 `ident' field to SilcServerCommandPending structure to identify
3615 the reply and to call correct callback.
3617 Added silc_server_command_pending_check function to replace the
3618 corresnponding macro. The silc_command_pending list is not
3621 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3622 to set identifier to previously allocated Command Payload. It
3623 is used to set identifier for command when resending Command
3626 * Added silc_command_payload_encode_payload to encode Command
3627 Payload buffer from SilcCommandPayload structure.
3629 * Added silc_argument_payload_encode_payload to encode Argument
3630 payload buffer from SilcArgumentPayload structure.
3632 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Changed WHOIS command to support router connection on server side.
3635 The whois request is always sent to router unless the server is
3636 standalone server. After server has received the reply from the
3637 router will it send the reply to the client.
3639 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3640 broadcast received broadcast packet. The function is used only
3641 by router. The broadcast packet is always sent to the router's
3644 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3645 render given ID to printable string, for log files for example.
3647 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Made basic router to router connections working. At least they
3650 can now connect to each other but nothing really works the way
3651 they are supposed - yet.
3653 * Added new initiator token to RouterConnection configuration
3654 file in silcd/serverconfig.[ch]. It is used to tell whether we
3655 are the initiator to the remote router or whether we'll expect
3656 the other end to connect.
3658 * Moved registering of listener task to silc_server_init, hence
3659 the server starts listenning as soon as it is run, even if it
3660 does not have connections to other routers. Let's see how well
3663 * Changed default connection retry timeouts for more suitable in
3666 * Removed cipher and such arguments from silc_idlist_add_client
3667 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3668 Added new function silc_idlist_add_data to add the keys and stuff
3671 * Added SilcIDListData structure and added it to SilcClientEntry
3672 and SilcServerEntry as their first field in the structure. This
3673 way we can explicitly cast the ID entries to the SilcIDListData
3674 structure and get common data for the entries. In past, we had
3675 to first check what type of connection it is and then cast it to
3676 correct ID entry type. Now, we can directly cast the opaque
3677 pointer to the SilcIDListData (no matter what ID entry it actually
3678 is) and get the data needed.
3680 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3683 in some circumstances even if threre were timeout tasks, though not
3684 IO tasks, but tasks anyway. Now fixed.
3686 * Defined SilcServerConnection structure to hold connection specific
3687 stuff about directly connected servers and routers. The definition
3688 is currently in silcd/server_internal.h. I thought about having
3689 a bit more important role fro this struct but for now it is used
3690 only when connecting to other server (or router actually).
3692 * Added connecting retry support in server when connecting to
3693 router(s). The retry feature implement exponential backoff
3694 algorithm. Also, added SilcServerParams structure to hold default
3695 parameters for server. For now, it include these retry settings
3696 and are hard coded. After server is moded to be as Silc Server
3697 Library this structure will be more important.
3699 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Changed client librarys channel->clients table to SilcList and
3702 changed code accordingly.
3704 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Changed client's channel table to SilcList and changed code
3707 accordingly. Also changed SilcChannelClientEntry to include back-
3708 pointer to the channel so that client entry can use that structure
3709 as list as well and we have fast cross-reference to the channel.
3710 This change dramatically decreased the complexity of channel
3711 handling with client entry and vice versa (removed one extra
3712 loop when searching for channel entry from many functions).
3714 * Changed server->sim from table to SilcDList and changed code
3717 * NAMES command can now be used from user interface. It will show
3718 the user list on the channel, neatly.
3720 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3721 Code now saves realname of the user if it becomes available.
3723 * Renamed configure.in to configure.in.pre and made ./prepare
3724 script to automatically add correct version string to
3725 configure.in which it creates from configure.in.pre.
3727 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * NAMES command reply now shows users mode with the nickname when
3732 * Moved silc_client_ch[u]mode[_char] functions from
3733 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3734 place sucks, they are utility functions and should be in some
3737 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3739 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3742 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Added TRQ (efficient deque and list library) into lib/trq. This is
3747 a very good list library that is currently used in the SILC. Defined
3748 SilcList API over the library because I didn't like the API very
3749 much. See lib/trq/silclist.h for the API and examples of how to
3750 use the API. Fixed various places in the code to use the new
3751 SilcList API. The SilcList is meant for lists that has a structure
3752 already defined as a list. It is not suitable to add just some
3753 context to the list (in TRQ, the context is the list actually).
3755 So, I defined SilcDList that can be used for the purpose where
3756 predefined list structure does not exit. This can be used as
3757 such list. Now some context just can be added to the SilcDList.
3758 Currently this list is not used in the SILC just yet, though there
3759 are a lot places where this can replace dynamically allocated
3760 tables and I will fix these places, later, to use SilcDList.
3761 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3762 and use TRQ internally).
3764 Also fixed some annoying warning messages that the original TRQ
3765 code generated. Also minor changes to TRQ's Makefile.in.
3767 * Added support for querying by Client ID to both WHOIS and
3768 IDENTIFY commands into server, as required by the protocol.
3770 * Removed method function pointers from SilcBuffer structure. They
3771 weren't used to anything and just increased the context size for
3772 no good reason. This change also made silc_buffer_alloc and
3773 silc_buffer_free functions inline functions.
3775 * Disabled command flooding detection support until it's fixed so
3776 that it accepts commands in but does not execute them more than once
3779 * Added silc_net_localhost(), to return local hostname, into
3780 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3781 that must be initialized before calling silc_client_init.
3783 * Added new function: silc_server_send_notify_on_channels to send
3784 notify messages to all channels client has joined. It is assured
3785 that the message is sent only once per client.
3787 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3788 lib/silcutil/silcutil.[ch] as silc_format function. The new
3789 function is generic and is used by server as well, not only by
3790 the logging routines.
3792 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3793 the provided version string was not acceptable. Added new function:
3794 silc_ske_check_version into lib/silcske/silcske.h. The function
3795 must be implemented by the application (client or server) and it
3796 does not reside in the SKE library. The function checks the version
3797 string remote end sent.
3799 * Added back pointers (to opaque context and to SilcSocketConnection)
3800 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3802 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3803 duplicate packet context structure.
3805 * Changed `notify' client operation to send same arguments as client
3806 receives from server except for ID's. ID's are mapped to correct
3807 ID entry and that is returned. Also, if channel entry is not sent
3808 by server but the notify is for channel the channel entry is sent
3809 to application (otherwise application doesn't know that it is for
3810 channel (library gets it from packet's Destination ID)).
3812 * Added silc_client_remove_from_channels into client library to
3813 remove a client from all channels it has joined to. Used when
3814 received SIGNOFF notify from server. Added also new function
3815 silc_client_replace_from_channels to replace old ID entry with
3816 new ID entry on all channels. Used when received NICK_CHANGE
3819 * Fixed ID Cache list handling in silc_idlist_get_client in
3820 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3821 to get (or query) client by ID.
3823 * Updated TODO list.
3825 * Added connection authentication status message defined by the
3826 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3827 support for these into the code in client and server side.
3829 * Added generic function silc_client_send_command to send any command
3830 with variable argument list. Application should use this function
3831 to send commands if the command functions provided by the library
3832 does not suite for the application's user interface needs.
3834 * Added new `failure' client operation. Application is notified about
3835 received failure packet if client is executing a protocol. In this
3836 case the protocol's execution has failed.
3838 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3839 is required by the protocol.
3841 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3842 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3845 * Added status flag to SilcSKE object to indicate realtime status
3846 of the SKE protocol.
3848 * Application receives now exactly same command reply arguments as
3849 the library receives from server. However, if ID is received the
3850 corresponding ID entry is returned to the application (eg. Client
3851 ID is mapped to correct SilcClientEntry entry and that is returned).
3852 Changed command_reply client operation due to this change.
3854 * Changed all ID's in commands and in command replys as ID Payloads.
3855 Change affected both client and server side codes.
3857 All ID's sent in SILC network (with execption of ID's in SILC
3858 Packet header) are sent in ID Payload to support variable length
3861 * Server now notifies nick changes and notifies all clients on
3862 the channels about the new nickname (about the new Client ID,
3865 * Implemented CMODE command to change channel modes. Supports all
3866 channel modes defined by the protocol specs except ban and invite
3867 lists. (Also, private channel key mode is supported but support for
3868 setting private channel key in client is missing, thus, this mode
3869 has no effect on client side (except that server requires that the
3870 client uses private channel key and normal channel traffic does not
3873 Also, invite mode works per se, but INVITE command does not work
3874 yet correctly, so you can set channel as invite only channel but
3875 inviting clients to the channel does not work (it is yet to be
3876 thought what's the best way to do it).
3878 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3879 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3880 Implemented CUMODE command to change user's mode on the channel.
3881 Supports all modes defined by the protocol specs.
3883 * Added NAMES command reply to return users modes on the channel.
3885 * Removed unnecessary and slow ciphers from lib/silccrypt.
3887 * Set SO_KEEPALIVE option to connection sockets by default.
3889 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3891 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3892 redefined the Notify Payload into protocol specs.
3894 * Added silc_id_payload_parse_id to get ID directly from raw
3897 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3900 accept searching by Client ID as well.
3902 * Added support for LEAVE and SIGNOFF notify types in client library.
3904 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3905 to parse ID Payload from raw data.
3907 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Added flags parameter into silc_ske_assemble_security_properties
3910 function in lib/silcske/silcske.[ch].
3912 * Changed notify client operation to fit better for notify messages
3913 sent by server. The notify payload received from server is now
3914 passed to the application (after parsing it to SilcNotifyPayload).
3915 It is application's responsibility to retrieve the arguments
3916 from the payload and show the message the way it wants. The message
3917 sent by server is implementation specific.
3919 * Changed public keys to comply with the protocol specification.
3920 Old public keys are not supported anymore and are not compatible.
3922 * Removed nickname from Channel Payload as the latest draft removed
3923 it. The client must resolve the nickname from the NAMES command
3924 reply received when it joined the channel.
3926 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3928 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Fixed some errors in protocol specification drafts.
3932 * Created lib/silccore/silcnotify.c to implement Notify Payload
3933 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3934 generic payloads described by protocol specifications. The file
3935 includes implementations for ID Payload and Argument Payload.
3937 * Changed Command Payload implementation to use the new Argument
3938 Payload. Changed command_xxxx_payload to command_payload_xxxx
3939 to comply with SILC coding conventions.
3941 * Added suppport for Argument Payload handling in Notify Payload
3942 implementation as protocol requires it. Added the new support
3943 into server and client lib as well.
3945 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Added support for multiple nicknames on same channel. [n] is
3948 added locally to the nickname if there are more than one same
3949 nicknames on the channel.
3951 * Server now sends all nicknames that matched WHOIS request.
3952 Client also shows the list received from server.
3954 * Added TOPIC command to client side. User can now set and show
3955 current topic on channel.
3957 * Added MOTD command to client and server. Also, server sends the
3958 motd when client connects to the server.
3960 * Changed version strings to comply ISO 8601.
3962 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Fixed protocol error handling in client library. It should now
3965 cope even if the SKE fails for some reason.
3967 * Made new protocol specification drafts for submitting to IETF.
3969 * Implemented TOPIC command to server in silcd/command.c.
3971 * Added two new notify types into lib/silccore/silcnotify.h:
3972 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3973 notify nickname change and topic setting/change on a channel.
3975 * API change of command_reply operation in client library. The
3976 application gets now the status type received from server as well.
3978 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3982 * Cras fixed and optimized the packet handling even further and
3983 it should work now. Minor change to the prototype of function
3984 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3986 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Added new function into lib/silcutil/silcschedule.[ch]:
3989 silc_schedule_with_fd to select() a specified fd. The function
3990 returns after timeout expires or data arrives or goes. The
3991 function is used by packet routines to wait that all data is
3992 received from network.
3994 * Fixed data reading from network in lib/silccore/silcpacket.c.
3995 The code now assures that all data is read from the fd and then
3996 continues packet processing. This was a bug fix since the code
3997 used to drop some data in some circumstances.
3999 * Added new function into lib/silcclient/client.[ch]:
4000 silc_client_start_key_exchange to start key exchange after
4001 connection has been established to server. The code internally
4002 now uses this funtion but its main purpose was to provide it
4003 for applications that perform their own connecting. After
4004 application has created a connection it merely calls this
4005 function to start the key exchange between client and server.
4006 The library takes care of everything else after that.
4008 Updated also lib/silcclient/README to explain the usage of
4011 * Do not send to application information that connection has
4012 been established. Application gets notified it by connect
4015 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Applied cras's patch to add silc_schedule_one function. The
4018 function runs scheduler once and returns.
4020 * Fixed the scheduler after cras messed it up. The timeout
4021 handling works now as it's supposed to work.
4023 * Added into lib/silccore/ silcnotify.h to include notify
4024 message types support. Changed silc_server_send_notify*
4025 functions, in server.[ch], to support those new notify types.
4026 Added the support for the notify types into client library,
4027 as well. Added new notify client operation into ops.h in
4030 * Changed silc_server_packet_send_to_channel to send normal
4031 packets instead of just channel message packets. The function
4032 is now used to send the notify packets to channels. It is not
4033 used to send channel message packets anymore, as server never
4036 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4037 va_arg()s as it seems to require it nowadays. I guess, if SILC
4038 is compiled with older va_arg() the new code should work anyway.
4040 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Splitted core library. Core library (lib/silccore) includes
4043 now only SILC protocol specific core (and common) components.
4044 Created new utility library (lib/silcutil) that includes more
4045 generic purpose stuff. The stuff for util library was taken
4046 from the old core library. This was minor and easy split.
4048 * Created SILC Client Library (lib/silcclient) that includes
4049 implementation of the SILC client without user interface. This
4050 was major move from silc/ directory. The code has been changed
4051 so that it is transparent towards the user interface. The
4052 silc/ directory includes now the same user interface as before
4053 and it uses the new client library. Read lib/silcclient/README.
4054 Basicly, the client library performs everything else related
4055 to SILC except user interface handling. Also, configuration
4056 files are considered to be part of user interface and library
4057 does not handle them.
4059 This change also changed a lot of structures, function naming etc.
4060 Most important change was that SilcClientWindow object was
4061 renamed to SilcClientConnection in the client library. Created
4062 also new file lib/silcclient/ops.h. Also added new files
4063 silc/local_command.[ch] and silc/client_ops.[ch].
4065 All these changes were made to make it easier for user interface
4066 designers to create what ever user interface for the SILC client
4069 It is also expected that the server will be moved to lib
4070 directory as well and SILC Server Library will be created;
4071 sometimes in the future.
4073 * Removed Local commands from lib/silccore/silccommand.h as
4074 they are application specific and new client library does not
4075 handle any of those anymore.
4077 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4078 old client implementation in silc/.
4080 * Added support for callback functions in SILC_LOG_* macros.
4081 Application can now set its own callbacks that will be called
4082 instead of using the default functions that will always print
4083 the debug messages to stderr (or stdout). Also, debugging can
4084 now be disabled by setting silc_debug to FALSE and re-enabled by
4085 setting it to TRUE. Note, that logging will still work even
4086 if debugging is disabled.
4088 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4089 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4090 silc_log_reset_debug_callbacks.
4092 * To enable debugging in silc client one must give now -d
4093 option on command line.
4095 * Changed silc_schedule_init to automatically allocate task queues
4096 if they are not allocated before calling it.
4098 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Added GMP 3.1 into math library.
4102 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4105 a channel in SILC network. The packet is used by servers and
4106 routers to notify other routers that user has left a channel.
4107 This little feature was missing until now. Added the feature
4108 to protocol specification as well.
4110 Added functions: silc_server_send_remove_channel_user and
4111 silc_server_remove_channel_user into server.[ch].
4113 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4114 lib/silccore/silcpacket.h. However, they are not implemented
4117 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Fixed joining to a channel and sending channel messages
4120 between server and router. The channel message sending should
4121 now work inside a cell.
4123 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Fixed the private message sending between server and router.
4126 The private message sending should now work inside a cell.
4128 * Added silc_server_replace_id into server.[ch] to replace
4129 existing ID in the SILC network.
4131 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4132 and silc_idlist_replace_server_id into idlist.[ch] in server.
4134 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Fixed the server to server connections. Server can again now
4137 connect to router. Router to router connections probably does
4140 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Added dynamic protocol registering support. Now protocols can
4143 registered and unregistered on the fly. Patch by cras.
4145 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Added lib/contrib directory to hold routines that some platforms
4148 don't have but are needed by SILC.
4150 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4151 into lin/contrib to provide getopt() and getopt_long() for
4152 those who don't have it.
4154 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Added AWAY command to client. When away message is set and
4157 client receives a private message packet the client automatically
4158 replies to the sender with the away message.
4160 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4161 bug seemed to be the cause of recent problems when compiling
4164 * Added version detection support to SKE protocol specification
4165 and added the new changes to the SKE implementation as well.
4166 There were other minor changes in the SKE protocol as well.
4168 Many changes in lib/silcske/silcske.[ch] and in
4169 lib/silcske/payload.[ch].
4171 * Added ^U functionality, clear input line. Patch from cras.
4173 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Mainly small bugfixes on core library. Fixed some debugging
4176 logging and buffer overflow in silclog.c.
4178 * Updated config.sub and config.guess on the distribution tree.
4180 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4182 * Added command lagging support in server. Client may execute
4183 commands now only once in two seconds.
4185 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Optimized packet reception. MAC computation and checking is now
4188 also more optimized. A lot previously duplicated code is now
4189 used as generic by both client and server.
4191 * Fixed key pair generation in clientutil.c
4193 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Added into lib/silccore/silcbufutil.[ch] new function;
4196 silc_buffer_realloc.
4198 * Moved generic packet sending/encryption functions to
4199 lib/silccore/silcpacket.[ch] from client and server. Some
4200 rewriting of the functions.
4202 * Moved all generic packet reception/decryption functions to
4203 lib/silccore/silcpacket.[ch] from client and server. The
4204 packet processing is now much cleaner in both client and server.
4205 These were major changes in both client and server.
4207 * Created many common functions in server to do packet sending.
4208 Previously code were duplicated a lot, this has been removed
4211 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Rewrote major parts of the ID cache system. Don't know
4214 whether it is better now or not but at least the API is more
4217 * Major rewrite on ID cache stuff on client because of the ID
4218 cache API changes. Added idlist.c to client.
4220 * Also major rewrite on ID cache stuff on server as well.
4221 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4222 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4223 in hand, instead they are all put into the ID cache system now.
4224 All server_idlist_* routines uses ID cache now instead of
4225 traversing its own lists (those lists does not exist anymore).
4226 SilcIDList though still exists. Also, SilcXXXEntry's are
4229 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Finally made the SKE implementation compliant to the protocol
4232 specification. All mp integers are now binary encoded as
4233 opposed being HEX encoded.
4235 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4238 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4239 functions: silc_[encode/decode]_pem. Also added function
4240 silc_encode_pem_file to PEM encode with newlines ('\n') for
4243 * SILC public keys are now encoded either PEM or binary. Same
4244 option is for private keys as well. By default private keys
4245 are binary encoded and public keys PEM encoded. Silly HEX
4246 encoding were removed.
4248 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4249 function to create fingerprints.
4251 * Fixed a bug in SHA1; does not change the original data anymore.
4253 * Partly implemented INFO command on client and server side.
4254 Fixed CLEAR command. Changes to SERVER command; show current
4255 server(s) when giving command without arguments. Added
4256 VERSION command to client.
4258 * Added check to server that unregistered connections cannot
4259 execute commands (unless it is specificly allowed).
4261 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Fixed screen refresh.
4265 * Fixed channel joining bug from client. On some circumstances
4266 client tried to join to a channel it had already joined.
4268 * Added public key verification process into client's protocol.c.
4269 The client now verifies the public key from user and saves
4270 it into ~./silc/serverkeys/ directory.
4272 Added into: clientutil.[ch]: silc_client_verify_server_key.
4274 * Changed SKE protocol's silc_ske_initiator_finish function
4275 to accept callback function that verifies the received public
4276 key. Removed old silc_ske_verify_public_key function.
4278 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4281 silc_pkcs_private_key[_data]_set.
4283 * Made the password and public authentication more cleaner in
4284 server's protocol.c.
4286 * Removed historic and obsolete protocol `channel_auth' from
4287 both client and server.
4289 * Removed wrong way of sending command status messages from
4290 server to client in server's command.c. The old way violated
4291 protocol specification.
4293 Changes to silccore/silccommand.[ch]: removed
4294 silc_command_encode_status_payload -> not needed anymore,
4295 changed silc_command_encode_payload_va to accept extra
4296 argument on variable argument list. The argument type must
4297 now be provided to the function. Also, added new function:
4298 silc_command_encode_reply_payload_va which is same as
4299 normal command_encode_payload_va except command status type
4300 is provided as extra argument.
4302 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Added ~./silc directory handling. The directory includes the
4305 public and private keys for the client.
4307 Added silc_client_check_silc_dir, silc_client_create_identifier
4308 and silc_client_load_keys.
4310 * Implemented SILC protocol compliant public key. Added public
4311 and private key saving to and loading from files.
4313 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4314 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4315 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4316 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4317 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4319 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4320 silc_pkcs_load_[public/private]_key.
4322 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Added silc_server_get_route (route.[ch]) to get connection
4325 data for the fastest route for given ID.
4327 * Implemented INVITE command on client and server. The command
4328 were re-defined in the SILC Protocol Specification and the
4329 implementation now complies with the specification.
4331 * Implemented PING command on client and server.
4333 * Implemented NAMES command on client and server. The server side
4334 supports currently only normal server not router server yet.
4335 Some changes to NAMES definition in SILC protocol specification.
4337 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Implemented LEAVE command on client and server.
4341 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4342 again. This change was made to the protocol as well. Server
4343 should not violate the protocol specification anymore.
4345 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4348 was tested. SOCKS4 was not but should work anyway.
