3 * Fixed the silc_parse_command_line to remove extra spaces
4 from the start and end of the arguments. Affected file is
5 lib/silcutil/silcutil.c.
7 * Cancel and free any active protocol in the function
8 silc_server_close_connection. Affected file silcd/server.c.
10 * Cancel and free any active protocol in the function
11 silc_client_close_connction. Affected file is
12 lib/silcclient/client.c.
14 * Do not execute the KILL command for clients that are in
15 history (ie. they are not in the network). Affected file is
18 * Fixed KILL notify handling, client does not crash anymore.
19 Affected file irssi/src/silc/core/silc-channels.c.
21 * Reduced the default packet buffer size from 2048 to 1024 in
22 lib/silccore/silcpacket.c.
24 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
25 counter to the SKE context that is incresed when the SKE library
26 performs async operation outside the library. If the outside
27 process frees the SKE context and FREED status will be set
28 and the library will detect after the sync operation that the
29 libary is freed. The affected files are
30 lib/silcske/silcske[_status].[ch].
32 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
34 * Fixed a possible crash in silc_packet_send_prepare. It now
35 assures always that there is enough space in the buffer and
36 at the tail area of the buffer (for MAC).
38 Fixed the inbound buffer reallocation in silc_packet_read.
39 It was old code and did not handle the reallocation correctly.
42 The affected file is lib/silccore/silcpacket.c.
44 * Fixed buffer overflow in silc_parse_nickname in the file
45 lib/silcutil/silcutil.c.
47 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
49 * make install generates new server keys only if there is not
52 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
55 Added check that if the NOREPLY is set then we will not send
56 the away message. This avoids infinite loop of away messages
57 if both clients are away. The affected file is
58 lib/silcclient/client_prvmsg.c.
60 * Fixed client crash if /NICK was given without arguments.
61 Affected file lib/silcclient/command.c.
63 * Server does not send the invite list in INVITE command back
64 to the client if the list was not altered. Added this notion
65 to the protocol spec as well. Affected file silcd/command.c.
67 Fixed possible crash in INVITE command by checking the
68 value of silc_server_get_client_route command.
70 * Fixed the INVITE notify type handling. The arguments are now
71 taken in correct order and client does not crash. The affected
72 file is irssi/src/silc/core/silc-channels.c.
74 Removed the "Inviting xxx to channel" message from the
75 client library away and let the application handle it.
76 Affected file lib/silcclient/command.c. Added that message
77 to Irssi SILC client's message formats.
79 * Fixed CMODE command crash in client. It now checks the
80 amount of arguments correctly and does not crash. The affected
81 file is lib/silcclient/command.c.
83 * Do not create new channel automatically in silc_channels_join
84 but check whether the channel by that name already exists.
85 Affected file irssi/silc/core/silc-channels.c.
87 * Do not send the SERVER_SIGNOFF to router if the disconnected
88 entity was the router. Affected file silcd/server.c.
90 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
91 SILC client as it was missing from there.
93 Added the handling of the KICK notify to the Irssi SILC client
94 as it was missing. Added "you have been kicked" message to
95 Irssi SILC client's message modules formats.
97 Added the handing of the KILL notify to the Irssi SILC client
98 as it was missing. Added the kill message module formats
101 The affected file is irssi/src/silc/core/silc-channels.c.
103 * The router did not save the channel mode the server announced.
104 Affected file silcd/packet_receive.c.
106 * Fixed a possible crash in INFO command in server. If the
107 server did not provide the server info it crashed. Affected
108 file silcd/command.c.
110 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
112 * Fixed the GETKEY command in the server to check also the
113 global list. Otherwise the GETKEY would not work correctly
114 in normal SILC server. Affected file silcd/command.c.
116 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Fixed GETKEY crash, it crashed if the command did not succseed.
120 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
122 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
123 is now real and not just an macro interface to GMP.
125 Removed the entire GMP from the source tree and imported new
126 NSS MPI library instead. Reason for removing GMP is that it is
127 extremely large and compiles extremely slow. The NSS MPI
128 is only a few files and compiles in less than 10 seconds.
129 The speed is also about the same as GMP. The MPI is imported
132 If the system has GMP installed we will still use the GMP.
133 If it is not then the NSS MPI will be compiled.
135 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
137 * Merged a long nickname (127 characters long) crash bugfix from
138 Irssi CVS tree. Affected file irssi/src/core/misc.c.
140 * Merged a freed memory reference bugfix from Irssi CVS tree.
141 Affected file irssi/src/core/commands.c.
143 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Added the server's public key sving and verification to the
146 server when performing the SKE. This was missing and the
147 remote server's (or router's) public key was accepted without
148 checking whether we have it previously or trust it at all.
149 Affected file silcd/protocol.c.
151 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Check in the silc_server_timeout_remote if protocol is active
154 and make sure that the protocol's final callback is called so
155 that all memory if freed. Affected file silcd/server.c.
157 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * silc_server_whois_send_reply crashed the server if the nickname
160 was 127 characters long. Affected file silcd/command.c.
162 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * Added sanity check to the silc_server_new_client. If the hostname
165 is provided inside username then check that the provided hostname
166 really is the same as the resolved one. If the hostname was not
167 resolved then check it from the public key. Affected file is
168 silcd/packet_receive.c.
170 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
171 if the server disconnected us and the connection is not valid
172 anymore. Affected file irssi/src/silc/core/silc-channels.c.
174 * Moved the silc_client_[chmode|chumode|chumode_char] away from
175 the library to the lib/silcutil/silcutil.[ch].
177 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Close log file after open. Affected file
180 lib/silcutil/silclog.c.
182 * Check whether sock == NULL in silc_client_send_packet and return
183 if it is. Affected file lib/silcclient/silcclient.c.
185 * Check rec->entry == NULL in the Irssi SILC Client before
186 sending the channel message. Affecte file is
187 irssi/src/silc/core/silc-servers.c.
189 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Merged a splitted window bugfix from Irssi CVS tree. The
192 affected file is irssi/src/fe-text/textbuffer-view.c.
194 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
195 It did not print nickname.
197 * Improved the distributions system a bit.
199 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
202 irssi/src/fe-text/gui-window.c.
204 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
205 to in-active server. The affected file is
206 irssi/src/silc/core/client_ops.c.
208 * Resolve the client in USERS command reply if the entry does
209 not have username resolved. The affected file is
210 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
211 command to WHOIS command to really resolve stuff. The USERS
212 is not used any more in any critical section so WHOIS can
213 be used even though it might be slower than IDENTIFY.
215 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
218 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
220 * Changed the protocol API a bit more consistent in the
221 lib/silccore/silcprotocol.[ch].
223 * Changed the following headers to ROBODoc format:
225 lib/silccore/silcpayload.h
226 lib/silccore/silcprotocol.h
227 lib/silccore/silcsockconn.h
229 All core library headers are now formatted.
231 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
233 * Fixed a bug in Irssi SILC client; do not show that you are
234 server/router operator if you really are not. Affected file is
235 irssi/src/silc/core/client_ops.c.
237 * Renamed silc_command_free_payload to silc_command_payload_free.
238 Affected file lib/silccore/silccommand.h
240 * Added silcmath.h to include the prototoypes of various routines
241 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
244 * Changed the following headers to ROBODoc format:
246 lib/silccore/silcchannel.h
247 lib/silccore/silccommand.h
248 lib/silccore/silcid.h
249 lib/silccore/silcidcache.h
250 lib/silccore/silcmode.h
251 lib/silccore/silcnotify.h
252 lib/silccore/silcpacket.h
253 lib/silcmath/silcmath.h
255 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
257 * Added checking to the server code not to start the server if
258 ciphers and stuff are not configured properly. Affected files
259 silcd/serverconfig.[h] and silcd/server.c.
261 * Changed the layout of the header files of the public interfaces
262 in the SILC libraries. The new layout supports ROBODoc
263 documentation tool (and some others) so that it is easy to create
264 a library reference manual. All the other headers and source
265 code must still follow the CodingStyle document. Also source
266 code must not include these ROBODoc stuffs, only the headers.
267 Furthermore, all public interface headers must now be named
268 by using `silc' prefix, example: silcapi.h, silccipher.h.
269 Some files were renamed due to this. All the other headers
270 must not be used as public interfaces. I will update the
271 CodingStyle document later. Changed following headers, so far:
273 lib/silcclient/silcapi.h
274 lib/silccore/silcauth.h
275 lib/silccore/silcprivate.h
276 lib/silccrypt/silcdh.h
278 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Removed silc_client_packet_send_flush from the client library
283 as it is not needed. Affected file lib/silcclient/client.[ch].
285 * Added printing of message of unresolved authentication method
286 to the Irssi SILC client. Added it to the module formats.
287 Removed the same message from the client library.
289 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
291 * Added new distribution feature, DISTLABEL. Every distribution
292 can define own preprocessor label that can be used in the
293 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
294 file distributions, acconfig.h.pre and prepare.
296 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
298 * Added Makefile.defines_int to include the actual definitions
299 for Makefile.defines.in. Tested the new distribution system,
300 created distributions and tested installation.
302 * Added AWAY message printing to the Irssi SILC client. Added
303 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
305 * Added SCONNECT command to call the SILC's CONNECT command.
306 Cannot use CONNECT directly since Irssi uses that internally.
307 Affected file irssi/src/silc/core/silc-servers.c.
309 Added ACTION local command. It is same as ME command but takes
310 the channel as mandatory argument.
312 Rewrote some of the Irssi's help files to suite for SILC
315 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
317 * Added Makefile.defines[.in] that should for now on be included
318 in all Makefile.am file in the source tree. That file includes
319 all common compilation definitions for SILC source tree.
321 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Minor changes to the ./prepare script to change the package
324 name according the distribution name to the configure.in.
326 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
328 * Created new distribution system. Added file `distributions'
329 that defines all the distributions that can be created out of
330 the SILC source tree. The ./prepare script now reads that
331 file to determine how to prepare the distributions. The
332 first argument to the ./prepare is the name of the distribution
333 and second is the version of the distribution. If given
334 without arguments it creates the default (toolkit) distribution
335 with the default version (defined in ./prepare).
337 All Makefile.am files that are subject to the distributions
338 are now named as Makefile.am.pre. These are ./Makefile.am
339 and lib/Makefile.am. Others may be changed later.
341 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Added invite list, ban list, some key management and connection
344 error message printing to module formats in the Irssi SILC client.
346 * Added new silc_client_set_away_message to set the away message
347 that is back to the person who sent private message. The
348 affected file lib/silcclient/silcapi.h and the
349 lib/silcclient/client_prvmsg.c.
351 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Fixed the private message sending in the Irssi SILC client,
354 added local command KEY to the Irssi SILC client.
356 Added key management and key agreement message formats to the
357 irssi/src/fe-common/silc/module-formats.[ch].
359 Added USERS (alias WHO) printing, server/router operator
360 indication and LIST command printing to the module formats.
362 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Fixed channel joining notify handling, cumode notify handling
365 from Irssi SILC client.
367 * Added SILC specific module-formats to the Irssi SILC client so
368 that SILC specific message hilighting, colors etc is possible.
369 Affected file irssi/src/fe-common/silc/module-formats.[ch].
371 Added channel mode, channel user mode, actions, notices,
372 whois and whowas printing to the the module-formats.c.
374 * Fixed a bug in channel deletion in the server. The channel
375 is not left to the cache even if the channel founder auth mode
376 is set when there are no users anymore on the channel. Affected
379 * The silc_net_localhost now resolves the entire hostname including
380 the domain name. Affected file lib/silcutil/silcnet.c.
382 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Changed the ask_passphrase client operation to be ascynchronous.
385 It has now a completion callback and a context that the
386 application must call after it has got the passphrase from
387 the user. Affected files lib/silcclient/silcapi.h,
388 lib/silcclient/protocol.c, lib/silcclient/command.c and
391 Added SilcAskPassphrase callback that the application calls
392 to deliver the passphrase to the library.
394 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
395 The public key verification and especially a certificate
396 verification is asynchronous procedure.
398 Added new SILC_SKE_STATUS_PENDING status to indicate the
399 request is pending and a callback will be called to finalize
402 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
403 indicate that remote end did not send its public key (or
404 certificate), even though we require it. Added check for this
405 condition in the SKE. This was a security bug, now fixed.
407 Defined new SilcSKEVerifyCbCompletion callback that is called
408 when the verification process is completed.
410 The affected files lib/silcske/silcske_status.h and
411 lib/silcske/silcske.[ch].
413 * Changed the verify_public_key client operation to be async
414 as well. Defined SilcVerifyPublicKey callback that is used to
415 indicate the success of the public key verification process.
417 Changed the server and client to use the new async client
420 * Changed the Irssi SILC client's internal scheduler to be called
421 twice as many times as it used to be. As a result the client
422 should be a bit faster now. Affected file is
423 irssi/src/silc/core/silc-core.c.
425 * Added support to Irssi SILC client of asynchronous public key
426 verification and passphrase inquiry. Affected file is
427 irssi/src/silc/core/silc-core.c.
429 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
431 * Do not say "You have left channel %s" in client library.
432 Moved it to the application. Affected files are
433 lib/silcclient/command.c and silc/client_ops.c.
435 * Fixed silc_client_get_clients. Command context was not
436 duplicated and was freed memory in the callback. Affected
437 file lib/silcclient/idlist.c.
439 * Do not say "you are now talking..." on JOIN command in the
440 client library. The appliation must handle it.
442 * Do not say ".. changed topic to" in command reply in the
443 client libary. The application must handle it.
445 * Fixed TOPIC command sending in the client library.
447 * Fixed a memory leak in silc_client_command_free in the file
448 lib/silcclient/command.c.
450 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Imported a modified version of Irssi client to the source tree.
453 The Irssi will be used to create a new client called
454 Irssi SILC. Imported to irssi/.
456 Added silc_core_init_finish function to the Irssi. Affected
457 file irssi/configure.in.
459 A lot changes in the Makefile.ams around the irssi tree.
461 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Do not rehash if the new size is same as the old size of the
464 hash table, in the silc_hash_table_rehash*. The affected file
465 lib/silcutil/silchashtable.c.
467 * Replaced hash_table_del_by_context calls from the server
468 (when channel->user_list and client->channels) to the
469 hash_table_del as it is sufficient and faster.
471 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Added silc_hash_table_list, silc_hash_table_get and the
474 SilcHashTableList structure to provide an alternative way to
475 traverse the hash table. The affected files are
476 lib/silcutil/silchashtable.[ch].
478 * Changed the server's idlist routines to use the hash table
479 routines to optimize the code.
481 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * Replaced the client entry's `channel' list and channel entry's
484 `user_list' list to hash tables for optimized lookup. Changed
485 the code to use the hash table interface around the code.
486 Affected file lib/silcd/idlist.[ch].
488 * Added `auto_rehash' boolean argument to the function
489 silc_hash_table_alloc to indicate whether the hash table should
490 auto-rehash when it thinks is appropriate time. It will
491 increase the hash table size if the there is twice as much
492 entries in the table than the size of the table, and will
493 decrease the size if there are twice as less entries than
494 the size of the table.
496 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Fixed silc_xxx_get_supported to not crash at some circumstances.
500 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * silc_idcache_purge_by_context deletes the entry now by context
503 as it is supposed to do. Affected file lib/silccore/idcache.c.
505 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
506 client is not anymore valid (WHOWAS givens the info) and not
507 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
509 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Removed the `data' and `data_len' arguments from the ID Cache
512 interfaces and added `name' argument. ID Cache does not handle
513 anymore the binary data only a names associated with given ID.
515 * When hashing a Client ID with silc_hash_id the entire ID is
516 not hashed anymore, instead only the hash of the Client ID is
517 hashed. This way we can access the Client ID from the cache
518 with Client ID but with the hash of the ID (which is a hash of
519 the nickname) as well without any difference in performance.
521 Added also silc_idcache_find_by_id_one_ext to do one on one
522 searching when we have the actual ID. Added also function
523 silc_hash_client_id_compare. The affected files are
524 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
526 * When hashing the name associated with a ID it is always done
527 in lowercase. This way we can access the cache without worrying
528 about case-sensitivity, even though, for example nicknames are
531 * Fixed a bug in server with channel message sending. It put
532 wrong ID type as destination ID. The affected file
535 * silc_idcache_del_by_context now deletes from all hash tables
536 by context. Affected file lib/silccore/idcache.c.
538 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Changed the client library to use the new ID Cache interface.
541 Changes around the source tree.
543 * Added silc_hash_table_rehash_ext to rehash with specific
544 hash function. Affected file lib/silcutil/silchashtable.[ch].
546 * Added silc_hash_string_compare to compare two strings in the
547 hash table. Affected file lib/silcutil/silcutil.[ch].
549 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
551 * Added new function silc_idcache_del_by_context into the
552 lib/silccore/idcache.[ch].
554 * Changed the server's ID list routines to use the new ID Cache
555 interface. Changes around the source tree.
557 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added silc_hash_table_del[_by_context]_ext functions in to the
560 lib/silcutil/silchashtable.[ch].
562 Removed silc_hash_table_find_all* routines and added new
563 silc_hash_table_find_foreach to replace them.
565 Added silc_hash_table_replace_ext function as extended
566 replacing function. Separated the simple hash table interface
567 from the extended hash table interface in the file
568 lib/silcutil/silchashtable.h.
570 * Fixed minor bugs and changed it to use some of the new
571 hash table functions in lib/silccore/idcache.c
573 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Added new function silc_hash_table_find_all to return all keys
576 in the hash table by the specified key. As the hash table is
577 collision resistant it also makes it possible to have several
578 duplicate keys in the hash table. This function may be used to
579 find all of the keys from the hash.
581 Added user_context arguments to the SilcHashFunction,
582 SilcHashCompare and SilcHashDestructor to deliver user specified
585 Added new fuctions silc_hash_table_find[_all]_ext to do
586 extended lookup with specified hash and compare functions and
587 specified user contexts.
589 Added new function silc_hash_table_add_ext to add the key
590 with specified hash function and user context.
592 Added new function silc_hash_table_foreach to traverse all
593 entrys in the hash table. Added SilcHashForeach callback
596 Added new function silc_hash_table_del_by_context to delete
597 the entry only if the context associated with the key matches.
599 Affected files are lib/silcutil/silchashtable.[ch].
601 * Removed silc_hash_[server/client/channel]_id and added just
602 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
603 silc_hash_id_compare to compare two ID's using as the hash table
604 comparison function. Added also silc_hash_data to hash
605 binary data and silc_hash_data_compare to compare it.
607 * Removed silc_idlist_find_client_by_hash as it is not needed
608 anymore. Affected file silcd/idlist.[ch].
610 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
611 to use internally the SilcHashTable. The new ID Cache is a lot
612 faster than the old one. Some of the ID Cache interface was also
613 rewritten and obsolete and stupid functions were removed.
615 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Added entry_count field to the SilcHashTable to keep the number
618 of the entries in the table. Implemented the function
619 silc_hash_table_rehash. Added new function
620 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
622 Fixed a minor bug in silc_hash_table_free.
624 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
625 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
626 into the lib/silcutil/silcutil.[ch].
628 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Implemented a collision resistant hash table into the
631 lib/silcutil/silchashtable[ch]. See the header and the source
632 for the SilcHashTable API.
634 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Merged dotconf version 1.0.2 into lib/dotconf.
638 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Do not compile anything in lib/silcsim/* if the SIM support
641 is not enabled. The tree should now compile without problems
644 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
646 * Compiled the SILC under cygwin. Compiled and tested briefly
647 without problems. More tests needed. The SIMs didn't compile
650 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
652 * Fixed possible crash in silc_get_username in the
653 lib/silcutil/silcutil.c.
655 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
657 * Fixed a va_arg in silc/client_ops.c.
659 * Oops, RC5 routines were named AES and caused some problems
660 when not using SIM's. Affected file lib/silccrypt/rc5.c.
662 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * Added new SilcIDIP structure into the lib/silccore/id.h and
665 replaced the old `ip' fields from all SILC ID's to that type.
666 This is a step towards IPv6 support.
668 The silc_id_get_len takes now the ID as an extra argument.
669 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
670 both IPv4 and IPv6 based ID's.
672 The affected files are lib/silccore/id.[ch] and other files
673 around the tree using these routines.
675 * Removed the ID length arguments in server from various
676 silc_server_send_notify_* routines -> they are not needed
679 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Fixed memory leak in silc_encode_pem_file in the file
682 lib/silcutil/silcutil.c.
684 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * Check minor version as well in the SKE. Affected files are
687 silcd/protocol.c and lib/silcclient/protocol.c.
689 * Added --identifier option to the server so that an identifier
690 can be when creating the public key for the server. Affected
691 file is silcd/silcd.c.
693 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
694 lib/silccrypt/silcpkcs.c.
696 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Register default ciphers and stuff when using -C option with
699 the server. Affected file sildc/silcd.c.
701 * Put back the servers public key filename format, it is better
702 than the new one. For now, the client keys are saved with the
703 new filename format. The affected file silc/client_ops.c.
705 * Implemented the Cipher API for the rest of the ciphers that
706 did not implement it or implemented it the wrong way.
708 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
710 * Register default ciphers and stuff when using the -S option
711 in the client. Affected file silc/silc.c. Same also when
712 creating new key pair with -C option.
714 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Fixed the silc_verify_public_key client operation function to
717 save the public keys differently. The fingerprint is now
718 used as filename and not the hostname. This way also the
719 client keys are saved uniquely and not with hostnames. The
720 affected file is silc/client_ops.c.
722 * Trimmed the silc_hash_fingerprint function to remove extra
723 whitespaces from the end of the fingerprint. The affected
724 file is lib/silccrypt/silchash.c.
728 * Added silc_cipher_register_default function to register all
729 default ciphers. It can be used when configuration files
730 does not exist and the application does not want any specific
731 ciphers in any specific order.
733 The SilcDList is now used as silc_cipher_list dynamically
734 allocated cipher list. Removed the static list all together
735 and now all ciphers must be allocated to the dynamic list.
736 The silc_cipher_alloc routine was changed to check only the
739 All silc_cipher_* routines that used to return int returns
742 The affected files lib/silccrypt/silccrypt.[ch].
744 * The same thing was done to silc_hash_* as for silc_cipher_*
745 routines. Affected files lib/silccrypt/silchash.[ch].
747 * The same thing was done to silc_pkcs_* as for silc_cipher_*
748 routines. Affected files lib/silccrypt/silcpkcs.[ch].
749 Added also silc_pkcs_[un]register[_default] functions.
750 Removed the data_context from the PKCS API.
752 * Added silc_hmac_register_default function to register default
753 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
754 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
755 to unregister all hmacs at once.
757 * Register the default ciphers, hash functions, PKCSs and HMACs
758 if client's configuration file does not exist. The affected
761 * The client did not load the hash functions from the SIM
762 modules at all. Added support for this. Affected file is
765 * When decoding public key with silc_pkcs_public_key_decode, check
766 the supported algorithm only if PKCS are registered. Affected
767 file lib/silccrypt/silcpkcs.c. The same was done with the
768 silc_pkcs_private_key_decode.
770 * Fixed the SILC List routines to keep the list always in order.
771 It used to change the list's order when traversing the list but
772 not it preserves the order. Affected file lib/trq/silclist.h.
774 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Added the client library to use the SilcSocketConnection's
777 reference counter (by silc_socket_dup) to prevent the bug that
778 the socket object may be freed underneath async operation.
780 * The name resolv library checking fixes in the configure.in.pre.
783 * Created new version of the protocol drafts for future
784 development. The -03 drafts are the ones that will be changed
785 in the trunk now and the -02 will remain as they are.
787 * Send list of CUMODE notifys to the router when announcing
788 the channel users to the router. Affected file silcd/server.c.
789 If the router receiving channel founder CUMODE for a channel
790 that already has channel founder it will send CUMODE notify
791 to the sender to remove the channel founder rights from the
792 announced client. Affected file silcd/packet_receive.c.
794 * The CUMODE notify may now use Server ID as well as the entity
795 who changes the mode. Updated protocool specs.
797 * Updated INSTALL and README files.
799 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * New web pages in the http://silc.pspt.fi. The pages was
806 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
808 * Implemented the [DenyConnectin] config section in the server.
809 Added silc_server_config_denied_conn to check whether incoming
810 connection is denied. Affected file silcd/serverconfig.[ch].
812 * Do not check the ports when checking the incoming configuration
813 data if the port is 0, meaning any. Affected file is
814 silcd/serverconfig.c.
816 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * Fixed buffer overflow in silc_string_compare in the file
819 lib/silcutil/silcutil.c.
821 * Fixed double free in silc_server_command_leave in the file
824 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
826 * Fixed the version checking in the server. Affected file is
829 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
831 * Fixed the configuration data fetching when accepting new
832 connections in the server. Affected file silcd/server.c.
834 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added `sender_entry' argument to the function
837 silc_server_packet_relay_to_channel so that we can check
838 whether some destination actually belongs to the same route
839 the sender belongs (ie, we must not resend the packet to the
840 sender). Affected file silcd/packet_send.[ch].
842 * Added `servername' field to the SilcClientEntry in the server
843 to hold the name of the server where client is from. Affected
844 file is silcd/idlist.h.
846 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Moved the channel message encrypting in the router betwen
849 router connections from silc_server_channel_message to the
850 silc_server_packet_relay_to_channel since we want to check
851 whether we have anybody channel before encrypting anything.
852 Affected files silcd/packet_[receive/send].c.
854 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Fixed the [AdminConnection] server config section to support
857 multiple entries. Affected file silcd/serverconfig.c.
859 * Added support into the server to check the validity of the
860 incoming connection before executing any KE or authentication
863 * The connection configuration is now saved to the KE and
864 connection auth protocol contexts and not fetched anymore in
865 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
867 * The local hosts listenning address and port is also resolved
868 now when starting the server. We want to have the socket object
869 to include the real address and port for the listener. Added
870 new function silc_net_check_local_by_sock into the files
871 lib/silcutil/silcnet.[ch].
873 * Fixed a broadcast bug in server -> do not broadcast if we
876 * Fixed a routing bug. Do not route broadcast packets ever.
877 Broadcast packets must be processed always and not routed since
878 they may be destined to some other host than yourself and thus
879 would get routed without no good reason. Affected file is
882 * Added function silc_server_config_is_primary_route to check
883 whether primary router connection has been configured (a router
884 configuration that we are initiating). If there is not, we
885 will assume that there is only two routers in the SILC network
886 and we will use the incoming router connection as our primary
887 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
889 * Changed the order of the broadcasting. Broadcast _after_ the
890 packet has been processed not before. Affected file is
893 * Fixed a [ClientConnection] parsing bug. The port was never
894 parsed correctly thus resulting to port 0. Affected file
895 silcd/serverconfig.c.
897 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
898 argument and did not set the broadcast packet flag. Affected
899 file silcd/packet_send.c. Fixed same bug in the function
900 silc_server_send_notify as well.
902 * If we receive NEW_ID packet for our own ID in the server, ignore
905 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Removed the nickname from the Private Message Payload.
910 Updated the code and the protocol specs.
912 * Updated protocol specs for submitting to the IETF.
914 * Tweaked the Random Number Generator a bit. Affected file
915 lib/silccrypt/silcrng.c. Exported a new function
916 silc_rng_[global]_add_noise which can be used to add more
919 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Do not parse packets with different timeout when protocol
922 is active -> may cause problem with rekey. Affected file
925 * When server receives signoff notify it must not create
926 new channel key if the client is on any channels since the
927 sender of the signoff notify will create it.
929 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Added printing of error messages during SKE protocol from the
932 failure packet sent by server during SKE. Affected file
935 * Removed the client's failure_callback handling with timeout
936 and handle it immediately when received.
938 * The SKE library returned wrong type in SUCCESS and FAILURE
939 packets. They must be 32 bit MSB not 16 bit MSB.
941 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Ok, rewrote the logic of the re-key and now it seems to work.
944 I tested it on high traffic with frequent re-keys without
945 problems. Added hmac_receive (and renamed hmac to hmac_send)
946 in SilcClientConnection in lib/silcclient/client.h and
947 in SilcIDListData in silcd/idlist.h. Also, removed the
948 SilcPacketParserContext's cipher and hmac fields as they are
949 not needed anymore and actually caused some problems when
950 the ciphers and hmac's changed underneath the packet parser.
952 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
954 * If re-key protocol is active then process the incoming packets
955 synchronously since we must assure that icoming packets encrypted
956 with the old key is processed before the new keys is set to
957 use. This is true other packets than for REKEY packets.
958 Affected file silcd/server.c. The same was done to client library
959 as well, affected file lib/silcclient/client.c.
961 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Fixed bug in client and server to accept the force send if
964 the packet is send from silc_[server/client]_packet_process
965 function. Otherwise the packets are never delivered, oops.
967 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Disable force sending of packets when REKEY protocol is active.
970 We must assure that no packet is sent directly when rekey is
971 performed. All packets must be sent through packet queue.
972 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
973 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
974 function is silc_[server/client]_packet_send_real to check
977 * Replaced the SIM paths from example config files to
978 /usr/local/modules. Also, make install creates now
979 /usr/local/silc/logs directory to hold all the SILC server
982 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Made the configure.in.pre work on Solaris. Patch by salo.
986 * Made all ciphers compatible with non-x86 machines. Defined
987 CBC mode macros into lib/silccrypt/ciphers_def.h.
989 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * Fixed the make install.
993 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * When MAC computation fails the silc_packet_decrypt returned 0
996 even though it was supposed to return -1. Fixed this. The
997 affected file is lib/silccore/silcpacket.c.
999 * Do not replace the config files in /etc/silc (in make install)
1000 if they already exist. Affected file ./Makefile.am.
1002 * Do not send re-key packets immediately but through packet queue.
1003 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1005 * Changed silc_net_check_host_by_sock to return FALSE if the
1006 IP/DNS could not be resolved. Though, it returns the IP address
1007 now even if it could not resolve it (but returns also FALSE).
1008 Affected file lib/silcutil/silcnet.[ch].
1010 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Added silc_pkcs_decode_identifier to decode the public key's
1013 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1014 Added also silc_pkcs_free_identifier. Added also new context
1015 SilcPublicKeyIdentifier.
1017 * Added -S option to the silc client. It is used to dump the
1018 contents of the specified public key file.
1020 * Changed the PKCS api to return the public key length when
1021 setting the public key.
1023 * Fixed a fatal bug in the public and private key file loading.
1024 Affected file lib/silccrypt/silcpkcs.c.
1026 * Execute the packet parsing for client with zero (0) timeout
1027 if the protocol is active. Affected file silcd/server.c.
1029 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Made the key generation options to the silcd program. Added
1032 -C option, equivalent to client's option.
1034 * Added new [ServerKeys] config section to the server. It
1035 configures the server's public and private key.
1037 * Defined generic Public Key Payload into the protocol
1038 specification to send specific type of public keys and
1041 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1042 public key or certificate.
1044 * Implemented the GETKEY command to the server and to the
1045 client library and on user interface.
1047 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1049 * Made preliminary `make install' work.
1051 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Added SilcServerRekey context into silcd/idlist.h.
1055 * Added the PFS support as defined in the specification to the
1056 SKE protocol. Affected files lib/silcske/*.c.
1058 * Added `ske_group' field to the SilcServerRekey context to hold
1059 the number of the SKE group that is used with PFS in re-key.
1060 Affected file silcd/idlist.h.
1062 * Added PFS re-key support to the server. Affected file is
1065 * Added silc_protocol_cancel to cancel execution of the next
1066 state of the protocol. Affected file is
1067 lib/silccore/silcprotocol.[ch].
1069 * Added the re-key support with and without PFS to the client
1070 library. Re-key is performed once in an hour, by default.
1072 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1073 Added silc_client_rekey_callback and silc_client_rekey_final.
1074 Affected files are lib/silcclient/protocol.[ch] and
1075 lib/silcclient/client.[ch].
1077 * Removed the `hmac_key' and `hmac_key_len' fields from the
1078 SilcClientConnection structure; not needed. Affected file is
1079 lib/silcclient/client.h.
1083 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Do not ask whether user wants to use the negotiated private key
1086 for private messages, just use it. Affected file is
1087 silc/local_command.c.
1089 * Added `send_enc_key' and `enc_key_len' fields to the
1090 SilcIDListData structure since they are needed in the re-key
1091 phase. Affected file is silcd/idlist.[ch].
1093 * Implemented the simple re-key protocol into the server.
1094 Affected files silcd/server.c and silcd/protocol.[ch]. The
1095 re-key will be performed once in an hour, by default.
1097 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1098 Added silc_server_rekey, silc_server_rekey_callback and

1105 the PFS is to be performed in the re-key. Affected file is
1108 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1111 int64 of at least the xintXX size. If void * is less that 4
1112 bytes uint32 * will be used. Defined bool as boolean.
1114 * Changed _ALL_ unsigned long and unsigned int to uint32,
1115 unsgined short to uint16 in the source tree.
1117 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1118 not handle clients that has entry->data.registered == FALSE.
1119 They are not in the network anymore. Affected file is
1122 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Implemented the sending of the SERVER_SIGNOFF notify in the
1125 server. Affected file is silcd/server.c.
1127 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1128 Added also silc_notify_payload_encode_args into the
1129 lib/silccore/silcnotify.[ch].
1131 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1132 Affected file silcd/packet_receive.c.
1134 * Implemented the SERVER_SIGNOFF notify handling in the client
1135 library. Affected file lib/silcclient/client_notify.c. Also,
1136 implemnted the printing of the SERVER_SIGNOFF info to the
1137 application. Affected file silc/client_ops.c.
1139 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1140 if the deleting was successful. Affected file silcd/idlist.[ch].
1142 * Added support for public key authentication in the connection
1143 authentication protocol in the client library. Affected file
1144 lib/silcclient/protocol.c.
1146 * Changed the server's silc_idlist_get_clients_by_* interface
1147 to support already allocated array so that new entries may be
1148 added to pre-allocated array. Affected file silcd/idlist.[ch].
1149 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1150 and command replies.
1152 * All command reply functions in the server now calls the
1153 pending command callback even if error occured. This way the
1154 error will be delivered to the client as well. Affected files
1155 silcd/command.c and silcd/command_reply.c.
1157 * Fixed INFO command to return local server's info if no server
1158 was provided. Affected file lib/silcclient/command.c.
1160 * Removed RESTART command for good. Updated the code and the
1163 * Rewrote parts of the task system. It is a bit simpler now.
1164 Removed unsued task priorities. The affected files are
1165 lib/silcutil/silctask.[ch].
1167 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Moved the USERS printing from the library to the application.
1170 Affected files lib/silcclient/command.c and silc/client_ops.c.
1172 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1176 * Added channel key re-key support. The re-key is perfomed
1177 only by the router and is done once in an hour. Added `rekey'
1178 field to the SilcChannelEntry in the server. Affected files
1179 silcd/server.c and silcd/idlist.h.
1181 * Added silc_task_unregister_by_context into the file
1182 lib/silcutil/silctask.[ch].
1184 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Added SILC_UMODE_GONE mode to indicate when the client is not
1187 present in the SILC network. Added also support to the local
1188 command AWAY that will set this mode. Added support of showing
1189 "xxx is gone" in WHOIS command. The USERS command shows the
1190 gone status as well.
1192 * Fixed setting server and router operator privileges in the
1193 server's UMODE command. Affected file silcd/command.c.
1195 * Merged the SKE KE1 and KE2 payloads into one payload. The
1196 new KE payload is equivalent to the old KE2 payload.
1198 Cleaned up the SKE Start Payload parsing. It now uses the
1199 simple buffer unformatting to do the parsing. A lot faster
1202 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1203 to the SKE that is used to indicate whether both of the SKE
1204 parties should perform authentication. By default only the
1205 responder performs authentication. By setting this flag also
1206 the initiator must do authentication. By default it is unset
1207 since in normal SKE case, client to server connection, only
1208 the responder should do authentication. When doing SKE between
1209 two clients both should perform authentication. Updated the
1210 code and the protocol specs.
1212 * A little fix to IDENTIFY command in the server. Search the
1213 client first by hash not nickname. Affected file is
1216 * Fixed the silc_client_close_connection to support closing
1217 the client to client connections wihtout deleting too much
1218 data. Affected file lib/silcclient/client.c.
1220 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1221 are received if protocol used to be active but is not anymore
1222 the application would crash due to NULL pointer dereference.
1223 Affected files silcd/server.c and lib/silcclient/client.c.
1225 * Added `hash' field to the SilcClientConnection to include
1226 the hash function negotiated in the SKE protocol.
1228 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1229 to set the channel founder authentication data. A client can
1230 claim the founder rights later by providing the authentication
1231 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1232 This way the channel founder can regain the channel founder
1233 privileges even it is left the channel. This works only on
1234 local server and the client must be connected to the same
1235 server to be able to regain the founder rights. Updated the
1236 protocol specs accordingly.
1238 Added support to the CMODE command in the client to set the
1239 founder auth data. Read the README to see how to set it.
1241 Added support to the CUMODE command to claim the founder
1242 rights. Read the README to see how to do it.
1244 Added support for the founder authentication to the Channel
1245 Entry in the server. Affected file silcd/idlist.h.
1247 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1248 server's CMODE command. Affected file silcd/command.c.
1250 * Added the following new functions into lib/silccore/silcauth.[ch]:
1251 silc_auth_get_method and silc_auth_get_data.
1253 * The server now saves the remote hosts public key to the
1254 SilcIDListData pointer. Affected file silcd/protocol.c.
1256 * The normal server now does not remove the channel entry from
1257 the cache if the founder authentication data is set. It used
1258 to remove it if the founder was the last one on the channel on
1259 the server and left the channel. The auth data is saved and
1260 if the channel is re-joined later the old entry is used with
1261 the old auth data. Affected files silcd/command_reply.c and
1264 * Removed the `pkcs' field from the SilcIDListData structure
1265 in the server; it is not used. Affected file silcd/idlist.h.
1267 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1269 * Fixed packet processing on slow links. Partial packets were
1270 never re-processed because the incoming data buffer was cleared
1271 by the application. Application must not directly clear the
1272 sock->inbuf, the packet processing routines handle it. Fixed
1273 this in client library and in server.
1275 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Fixed the WHOIS and IDENTIFY send reply function to really
1278 check whether to send list or just one entry. Affected file
1281 * Cleaned up the LEAVE command's channel key distribution. The
1282 affected file silcd/command.c.
1284 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1285 can enforce the channel mode as well. In that case the ID
1286 includes the ID of the server. The code now enforces the
1287 mode change if the router have different mode than the server.
1289 * The notify client operation with CMODE_CHANGE notify can now
1290 return NULL client_entry pointer if the CMODE was not changed
1291 by client. Application must check for this.
1293 * Added <Server ID> argument to INFO command to support server
1294 info fetching by Server ID.
1296 * Added silc_server_announce_get_channel_users to get assembled
1297 packets of channel users of the specified channel. Affected
1298 file silcd/server.[ch].
1300 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1301 was freed underneath the ID Cache.
1303 * Re-announce clients when the server received CHANNEL_CHANGE
1304 notify from the router. Affected file silcd/packet_send.c.
1306 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1309 crashed since it did not handle the fact that there is no cipher
1310 called "3" and didn't check the error condition. Now fixed.
1312 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1313 flag. It can be used to send message requests.
1315 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * Implemented the RESTART command in the client.
1319 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1320 notice type messages. Added notice printing to the user
1323 * The channel keys are not re-generated if the channel's mode
1324 is PRIVKEY, ie private key on the channel exists. Affected
1325 files silcd/server.c and silcd/command.c.
1327 * Fixed a little bug in channel message delivery when channel
1328 private keys are set in the server. Affected file is
1329 silcd/packet_send.c.
1331 * Changed the setting on channel->on_channel = TRUE from the
1332 silc_client_save_channel_key to the JOIN command reply. The
1333 key payload is not received if the private channel key is set.
1334 Affected file lib/silcclient/command_reply.c and the
1335 lib/silcclient/client_channel.c.
1337 * When the CMODE_CHANGE notify is sent and the channel private
1338 key mode is removed the channel key must be re-generated in
1339 other cells as well. Added this support for the router in the
1340 silcd/packet_receive.c.
1342 * Added new local command NOTICE to send notice message on
1343 channel. Affected file silc/local_command.[ch].
1345 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Added new local command ME to the client. It is used to send
1348 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1349 some action. Affected file silc/local_command.[ch].
1351 * Changed channel_message and private_message client operations
1352 to deliver the message flags to the application. Added also
1353 the `flags' arguments to the silc_client_send_channel_message
1354 and silc_client_send_private_message functions. Affected file
1357 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Redefined the Private Message Payload to support private message
1360 keys and to support the new private message flags. Updated
1361 the protocol specs. Flags makes it possible to have for example
1362 CTCP style messages.
1364 * Added new type SilcPrivateMessagePayload and defined an API
1365 for it in the lib/silcclient/silcprivate.[ch].
1367 * Tested private message private keys successfully. Tested the
1368 private message key set, unset and list commands with the new
1371 * Redefined the Channel Message Payload to include the channel
1372 message flags (equal with private message flags) to support
1373 for example CTCP style messages.
1375 * Defined some of the message (for channel and private message)
1376 flags. Updated the protocol specs and added the flags to the
1377 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1379 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Added SilcKeyAgreementStatus type to the key agreement routines
1382 to indicate the current status and error if one occured.
1383 The status types are defined in the lib/silcclient/silcapi.h.
1385 * Added new local command KEY that is used to set and unset private
1386 keys for channels, set and unset private keys for private messages
1387 with remote clients and to send key agreement requests and
1388 negotiate the key agreement protocol with remote client. The
1389 key agreement is supported only to negotiate private message keys,
1390 it currently cannot be used to negotiate private keys for channels,
1391 as it is not convenient for that purpose.
1393 * Fixed a minor pending callback setting bug in the function
1394 silc_client_get_client_by_id_resolve, now the function works.
1395 Affected file lib/silcclient/idlist.c.
1397 * Added function silc_net_get_local_port to get local bound
1398 port by socket. Added to lib/silcutil/silcnet.[ch].
1400 * Added `sockets' and `sockets_count' fields to the SilcClient
1401 object. They hold the sockets of the listenning sockets in
1402 the client. Listenning sockets may be for example the key
1403 agreement server. Affected file lib/silcclient/client.[ch].
1404 Added functions the silc_client_add_socket and the
1405 silc_client_del_socket. They are exported to the application
1408 * Added ~./silc/clientkeys to support other client's public keys.
1410 * Renamed verify_server_key client operation to verify_public_key
1411 and added one argument to indicate the type of the connection
1412 (server, client etc.).
1414 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * Added silc_server_connection_auth_request to handle the
1417 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1418 silcd/packet_receive.[ch].
1420 * Added silc_server_send_connection_auth_request into the
1421 silcd/packet_send.c to send the connection auth request packet.
1423 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1426 * Fixed the public key authentication in responder side in the
1427 server. The `auth_data' pointer includes the SilcPublicKey
1428 not the path to the public key. Affected file silcd/protocol.c.
1430 * Implemented the public key authentication in the initiator side
1431 in the server. Affected file silcd/protocol.c.
1433 * Removed the [RedirectClient] config section from the server
1434 configuration. Is not needed and I don't want to implement it.
1436 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Cleaned up the CMODE command in the server. It now works
1439 correctly and supports all the modes defined in the protocol.
1440 Affected file is silcd/command.c.
1442 * Added `hmac_name' field to the SilcChannelEntry in the server
1443 to hold the default HMAC of the channel. It can be set when
1444 creating the channel (with JOIN command). Affected files
1447 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1448 type to indicate the change of the current cipher and hmac
1449 on the channel. Client can safely ignore the <cipher> argument
1450 (if it chooses to do so) since the CHANNEL_KEY packet will
1451 force the channel key change anyway. The <hmac> argument is
1452 important since the client is responsible of setting the new
1453 HMAC and the hmac key into use.
1455 * Fixed the CMODE command in the client library as well.
1457 * Tested CMODE command in router environment successfully.
1459 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Show the version of the remote client (or server) when connecting
1462 to the server. It is logged to the log file. Affected file
1463 is silcd/protocol.c.
1465 * Fixed the KILLED notify handling in the client library. The
1466 client must be removed from all channels when receiving the
1469 Also, do not remove the client entry when giving the KILL
1470 command but when the KILLED notify is received.
1472 * Removed silc_idlist_find_client_by_nickname from the server.
1473 Not needed anymore. Affected files silcd/idlist.[ch].
1475 * Implemented the CHANNEL_CHANGE notify type handling to the
1476 server. Affected file silcd/server.c.
1480 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Added silc_server_send_notify_invite to send the INVITE
1483 notify between routers.
1485 * Implemented the INVITE command correctly to the server.
1487 * Implemented the INVITE notify type handling in the server.
1489 * Implemented the INVITE command to the client library and on the
1492 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Added function silc_server_get_client_resolve to find the
1495 client entry by ID from all ID lists and then resolve it
1496 (using WHOIS) if it cannot be found. Affected file is
1499 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Implemented the BAN command to the client library.
1503 * The JOIN command in the server now checks the invite list
1506 * Changed the silc_command_reply_payload_encode_va and the
1507 silc_command_payload_encode_va to support that if argument is
1508 NULL it ignores and checks the next argument. Affected file
1509 lib/silccore/silccommand.c.
1511 * Added silc_server_send_notify_ban to send the BAN notify
1512 type between routers.
1514 * Chaned the silc_notify_payload_encode to support that if
1515 argument is NULL it ignores and checks the next argument.
1516 Affected file lib/silccore/silcnotify.c.
1518 * Tested ban lists in router environment successfully.
1520 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Implemented BAN command to the server, in silcd/command.[ch].
1524 * Removed the BAN and INVITE_LIST modes from the CMODE command
1527 * Added function silc_string_match to regex match two strings.
1528 Affected files lib/silcutil/silcutil.[ch].
1530 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Redefined parts of the SilcChannelEntry in the server to support
1533 the new ban and invite lists.
1535 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Redefined the INVITE command. The same command can be used to
1538 invite individuals to the channel but also to manage the invite
1539 list of the channel (to add to and remove from the invite list).
1540 Updated the protocol specs.
1542 * Added new command SILC_COMMAND_BAN that can be used to manage
1543 the ban list of the channel. Updated the protocol specs.
1545 * Removed the channel modes: the SILC_CMODE_BAN and the
1546 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1547 in the CMODE command. The equivalent features are now available
1548 using INVITE and BAN commands. Updated the protocol specs.
1550 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1551 in the network about change in the current ban list. The notify
1552 type is not used by the client.
1554 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1555 support the invite lists.
1557 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Added new function silc_string_regexify that converts string
1560 including wildcard characters into regex string that can
1561 be used by the GNU regex library. Added into the file
1562 lib/silcutil/silcutil.[ch].
1564 Added silc_string_regex_combine to combine to regex strings
1565 into one so that they can be used as one regex string by
1566 the GNU regex library. Added into the file
1567 lib/silcutil/silcutil.[ch].
1569 Added silc_string_regex_match to match two strings. It returns
1570 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1572 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Imported GNU regex to the soruce tree into lib/contrib.
1575 Fixed some compiler warning from the regex.c.
1577 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Fixed MOTD command in the server to work in router environment.
1581 * Fixed the MOTD command in the client library to support
1582 the server argument in the command.
1584 * Added `nickname_len' argument to the silc_idlist_add_client
1585 in the server, as the `nickname' argument may be binary data
1588 * Added silc_idlist_get_channels to return all channels from
1591 * Implemented LIST command to the server. Affected file is
1594 * Implemented the LIST command to the client library and on the
1597 * Added [<user count>] argument to the LIST command reply.
1598 With private channels the user count is not shown.
1600 * Updated TODO and README.
1602 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * The client entry's data.registered must be TRUE even with
1605 global client entry on global client list. The data.registered
1606 is used to check whether the client is anymore in the network,
1607 for example with WHOWAS command so it must be valid.
1609 * Fixed the WHOWAS command in the server. It now actually works
1610 in router environment. Added function into silcd/command_reply.c
1611 silc_server_command_reply_whowas_save.
1613 * Added silc_idlist_purge function to the silcd/idlist.c
1614 to periodically purge the ID Cache.
1616 * Fixed INFO command in the server. It works now in router
1617 environment. Added <server name> argument to the INFO command
1618 reply. Updated the protocol specs.
1620 * Fixed minor bug in silc_idcache_purge to not purge if the
1621 expire value is zero.
1623 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1624 they were buggy because of the WHOWAS information.
1626 * Fixed local command MSG to handle the async resolving of
1627 the remote client properly. It used to fail the first MSG.
1628 Affected file silc/local_command.c.
1630 * Added `data_len' field to SilcIDCache context.
1632 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Update TODO. Todo in commands in the server.
1636 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1639 used by routers as broadcast packet to inform other routers
1640 about the changed user mode.
1642 Implemented the notify handling in the server. Affected file is
1643 silcd/packet_receive.c. Added the function
1644 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1646 * Added new generic Channel Payload and deprecated the New Channel
1647 Payload. The New Channel Payload is now the generic Channel
1650 * Added new argument `mode' to the silc_server_send_new_channel
1651 as it is required in the Channel Payload now.
1653 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1654 and created a new and real SilChannelPayload to represent the
1655 new generic Channel Payload. Implemented the encode/decode
1656 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1658 * Added silc_server_get_client_channel_list to return the list
1659 of channels the client has joined for WHOIS command reply.
1660 Affected file silcd/server.[ch].
1662 * Implemented the channel list sending in the WHOIS command reply
1663 in server and in the client.
1665 Implemented the channel list displaying on the user interface
1666 as well. Affected file silc/client_ops.c.
1668 * Added silc_channel_payload_parse_list to parse list of Channel
1669 Payloads. It returns SilcDList list of SilcChannelPayloads.
1670 Client for example can use this function to parse the list of
1671 channels it receives in the WHOIS command reply. The caller
1672 must free the list by calling silc_channel_payload_list_free.
1673 Affected files lib/silccore/silcchannel.[ch].
1675 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Added one new argument <user mode> to the WHOIS command reply
1678 to return the mode of the user in SILC. Updated the protocol
1681 Implemented it to the server and client.
1683 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1685 * Fixed the mode printing on the user interface on joining.
1686 Affected file silc/client_ops.c.
1688 * Implemented the UMODE command and user modes in general to the
1689 client library and to the user interface.
1691 * Implemented the UMODE command to the server.
1693 * The server now sends UNKNOWN_COMMAND error status if client sends
1694 unknown command. Affected file silcd/command.c.
1696 * All server commands now handle the command identifier the right
1697 way when sending the command reply to the client. The client can
1698 use to identify the command replies with the identifier.
1700 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * Added silc_server_get_client_route to resolve the route to
1703 the client indicated by the client ID. Affected file is
1706 * Added silc_server_relay_packet as general function to relay
1707 packet to arbitrary destination. This deprecates functions
1708 like _send_private_message_key, _relay_notify etc. Affected
1709 file is silcd/packet_send.[ch].
1711 Removed silc_server_send_key_agreement,
1712 silc_server_send_private_message_key and
1713 silc_server_packet_relay_notify functions from the file
1714 silcd/packet_send.[ch].
1718 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1719 server. Affected file silcd/packet_receive.[ch].
1721 * Implemented the KILL command to the client. Implemented the
1722 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1723 Affected files lib/silcclient/command[_reply].c and
1724 lib/silcclient/client_notify.c. Implemented the KILL notify
1725 printing in the user inteface.
1727 * Fixed a lot silc_parse_nick memory leaks from the client
1728 library in the file lib/silcclient/command.c.
1730 * Changed the silc_server_send_notify_on_channels's `sender'
1731 argument from SilcSocketConnection to SilcClientEntry to
1732 check the sender as entry and not as connection object and not
1733 to send to the client provided as argument. The affected file
1734 is silcd/packet_send.[ch].
1736 * The notify packets that are destined directly to the client used
1737 to not to be processed by the server. Now changed that and the
1738 server processes all notify packets. After relaying the packet
1739 to the client the notify packet is processed in the server.
1741 * The silc_server_free_client_data now checks whether there is
1742 pending outgoing traffic for the client and purges the data to
1743 the network before removing the client entry.
1745 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1748 an client is killed from the SILC Network. Updated the protocol
1751 Added new function silc_server_send_notify_killed to the
1752 silcd/packet_send.[ch].
1754 * Added function silc_server_packet_relay_notify to relay notify
1755 packets that are destined directly to a client. In this case
1756 the server does not process the notify packets but merely relays
1757 it to the client. Affected file silcd/packet_send.[ch].
1759 Added also silc_server_packet_process_relay_notify to check
1760 whereto relay the notify. Affected file is
1761 silcd/packet_receive.[ch].
1763 * Implemented the KILL command to the server.
1767 * Added the backup schema desgined last fall to the protocol
1768 specs for everyone to see. The specification is in the
1769 *-spec-xx.txt draft and the packet type definitions for the
1770 backup routers is in *-pp-xx.txt draft. Thusly, added also
1771 new packet type SILC_PACKET_CELL_ROUTERS.
1773 * A big security problem in the implementation discovered. The
1774 signoff of an client did not cause new channel key generation
1775 which it of course should've done. The channel keys must be
1776 always re-generated when client leaves (or signoffs) the channel.
1777 The silc_server_remove_from_channels funtion now handles
1778 the channel key re-generation.
1780 * Added `sender' argument to the silc_server_send_notify_on_channels
1781 to not to send the client provided as argument. Affected file
1782 silcd/packet_send.[ch].
1784 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Implemented OPER and SILCOPER commands into the server and
1789 * Added silc_auth_verify and silc_auth_verify_data to verify
1790 the authentication directly from the authentication payload.
1791 It supports verifying both passphrase and public key based
1792 authentication. Affected file lib/silccore/silcauth.[ch].
1794 * Added `hash' field to the SilcIDListData structure. It is the
1795 hash negotiated in the SKE protocol. Affected file is
1798 * Slight redesigning of the SilcAuthPayload handling routines.
1799 Do not send SilcPKCS but SilcPublicKey as argument.
1801 * Implemented the public key authentication support to the
1802 serverconfig. The public key is loaded from the provided path
1803 and saved as authentication data to void * pointer. Thus,
1804 changed the unsigned char *auth_data to void *auth_data;
1806 * Fixed SHUTDOWN command to send the reply before the server
1807 is shutdown. :) Affected file silcd/command.c.
1809 * Fixed fatal bug in CONNECT command. The hostname was invalid
1810 memory and server crashed. Affected file silcd/command.c.
1812 * Fixed fatal bug in CLOSE command. The server_entry became
1813 invalid but was referenced later in the command. Affected file
1816 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Fixed fatal bug in failure packet handling. Server ignored
1819 the failure and thus crashed when it came.
1823 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1826 that the command may be executed only once in (about) 2 seconds.
1827 The old SILC_CF_LAG flag is same but allows command bursts up
1828 to five before limiting.
1830 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1831 server code. Various commands now includes the CF_LAG_STRICT
1832 flag to disallow any kind of miss-use of the command.
1834 * Fixed the silc_buffer_unformat to not to allocate any data
1835 if the length of the data is zero. It used to allocate the
1836 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1838 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * Changed the format of AdminConnection configuration section
1841 in the server. Added username of the admin to the format.
1842 Affected files silcd/serverconfig.[ch].
1844 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1845 to return admin configuration data by host, username and/or
1848 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Implemented WHOWAS command to the server. Added the functions:
1852 silc_server_command_whowas_parse,
1853 silc_server_command_whowas_send_reply,
1854 silc_server_command_whowas_from_client and
1855 silc_server_command_whowas_from_server
1857 * Added <Client ID> argument to the WHOWAS command reply. Updated
1858 the protocol specs accordingly.
1860 * Implemented WHOWAS command and command_reply to the client
1863 Implemented the WHOWAS printing on the user interface.
1865 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Added new argument to the WHOWAS command reply, the real name.
1868 It is an optional argument. Updated the protocol specs.
1870 * Added SilcIDCacheDestructor callback that is registered when
1871 the SilcIDCache is allocated. The callback is called when
1872 an cache entry in the ID Cache expires, or is purged from the
1873 cache. Added into lib/silccore/idcache.[ch].
1875 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1876 to destruct the client entries when the cache entry expires.
1877 Other ID Cache's in server and in the client library ignores
1880 * If the ID Cache entry's `expire' field is zero then the entry
1881 never expires. Added boolean `expire' argument to the
1882 silc_idcache_add function in the lib/silccore/idcache.[ch].
1883 If it is TRUE the default expiry value is used.
1885 * Added silc_server_free_client_data_timeout that is registered
1886 when client disconnects. By default for 5 minutes we preserve
1887 the client entry for history - for WHOWAS command.
1889 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1891 * Added support to the server to enforce that commands are not
1892 executed more than once in 2 seconds. If server receives
1893 commands from client more frequently, timeout is registered
1894 to process the commands. Affected file silcd/command.c.
1895 Added new function silc_server_command_process_timeout.
1897 * Changed NICK_NOTIFY handling in client library to check that
1898 if the client's nickname was changed, so there is no need to
1899 resolve anything from the server.
1901 * Removed error printing from the WHOIS and IDENTIFY commands.
1902 If error occurs then it is ignored silently in the client library.
1903 The application, however, may map the received error to
1904 human readable error string. The application currently maps
1905 the NO_SUCH_NICKNAME error to string.
1907 * Made the command status message public to the application. Moved
1908 them from lib/silcclient/command_reply.c to
1909 lib/silcclient/command_reply.h. The application can map the
1910 received command status to the string with the
1911 silc_client_command_status_message function.
1913 * Added check to the server to check that client's ID is same
1914 as the Source ID in the packet the client sent. They must
1917 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Added dist-bzip hook to the Makefile.am to make bzip2
1920 compressed distributions.
1922 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Server now enforces the maximum length for the nickname and
1925 the channel as protocol specification dictates. 128 bytes for
1926 nickname and 256 bytes for channel name.
1928 * Moved the WHOIS printing to the application. The client libary
1929 does not print out the WHOIS information anymore, the application
1930 must do it. Renamed silc_client_command_reply_whois_print to
1931 the silc_client_command_reply_whois_save.
1933 The client's idle time is also sent to the application now, and
1934 the idle is shown on screen.
1936 * Added silc_client_command_reply_identify_save to save the
1937 received IDENTIFY entries.
1939 * Do not check for channel private keys in message sending and
1940 reception if the channel does not have the PRIVKEY mode set.
1941 Affected file lib/silclient/client_channel.c.
1943 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1946 just surfaced after chaning the JOIN procedure.
1948 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Added silc_client_get_clients_by_list to get client entries
1951 from Client ID list, that is returned for example by JOIN
1952 and USERS command replies. The application should use this
1953 function for example when JOIN command reply is received to
1954 resolve the clients already on the channel (library does not
1955 do that anymore as USERS command reply is not used in the JOIN
1956 procedure anymore). Affected files lib/silcclient/silcapi.h and
1957 lib/silcclient/idlist.c.
1959 * JOIN command reply and USERS command reply returns now SilcBuffer
1960 pointers instead of unsigned char pointers when returning
1961 the client list and mode list.
1963 * Added <Client ID> argument to the JOIN command reply, mainly
1964 for the server to identify for which client the command was
1965 originally sent. Updated protocol specs accordingly.
1967 * Added SilcDlist private_key pointer to the SilcChannelEntry
1968 in the client to support the channel private keys. Affected
1969 file is lib/silcclient/idlist.h.
1971 * Added SilcChannelPrivateKey argument to the function
1972 silc_client_send_channel_message so that application can choose
1973 to use specific private ke if it wants to. If it is not provided,
1974 the normal channel key is used, unless private keys are set.
1975 In this case the first (key that was added first) is used
1976 as the encryption key.
1978 * Implemented the support for channel private key handling.
1979 Implemented the following functions:
1981 silc_client_add_channel_private_key,
1982 silc_client_del_channel_private_keys,
1983 silc_client_del_channel_private_key,
1984 silc_client_list_channel_private_keys and
1985 silc_client_free_channel_private_keys
1987 Affected file lib/silcclient/client_channel.c.
1989 * Added the support for the private keys in the channel message
1990 sending and encryption and in the message reception and
1991 decryption. Affected funtions are
1992 silc_client_send_channel_message and silc_client_channel_message.
1994 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Added SKE's key verify callback to the client library's
1997 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1999 * Removed the statement that server (or router) must send USERS
2000 command reply when joining to the channel so that the client
2001 knows who are on the channel. Instead, the client list and
2002 client's mode list is now sent in the JOIN command reply to the
2003 client who joined channel. This is better solution.
2005 * Added function silc_server_get_users_on_channel and function
2006 silc_server_save_users_on_channel to the silcd/server.[ch].
2008 * Removed function silc_server_command_send_users from the
2011 * Do not show topic on the client library anymore. The topic is
2012 sent in the command reply notify to the application and the
2013 application must show the topic now.
2015 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Added client searching by nickname hash into the IDENTIFY and
2018 WHOIS commands in the server as they were clearly missing from
2019 them. Affected file is silcd/command.c.
2021 * Fixed a bug in private message receiving in the client library.
2022 The remote ID was freed and it wasn't supposed, now it is
2025 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * Minor fix to the channel payload; allocate the data area, as it
2028 needs to be of specific length.
2030 * If the key agreement port is zero then the operating
2031 system will define the bound port. Affected files are
2032 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2034 * Added new function silc_channel_payload_decrypt into the file
2035 lib/silccore/silcchannel.[ch].
2037 * Moved the channel message etc, check from silc_packet_decrypt
2038 to applications. The library calls now a generic
2039 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2040 when the packet is either normal or special. This was done to
2041 allow more wide range of checking that was not allowed when
2042 the code was in library. Now applications can do virtually any
2043 checks to the packet and return to the library the decision how
2044 the packet should be processed. Affected files are
2045 lib/silccore/silcpacket.[ch].
2047 Added silc_server_packet_decrypt_check to the server and
2048 silc_client_packet_decrypt_check to the client library.
2050 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2051 to send with specified source and destination information.
2053 * Channel message delivery between routers was broken after the
2054 channel key distribution was fixed earlier. The channel key
2055 was used be to distributed to other routers as well which is not
2056 allowed by the protocol. Now this is fixed and channel keys
2057 really are cell specific and the channel message delivery between
2058 routers comply with the protocol specification.
2060 * Fixed various commands in server to check also the global list
2061 for the channel entry and not just the local list. The affected
2062 file silcd/command.c.
2064 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Added assert()s to buffer formatting and unformatting routines
2067 to assert (if --enable-debug) when error occurs. Affected
2068 file: lib/silcutil/silcbuffmt.c.
2070 * Changed to auto-reconnect to check whether the remote host is
2071 router and register the re-connect timeout if it is. It used
2072 to check that whether we are normal server, but router must do
2073 auto-reconnect with another router as well. Affected file
2076 * Removed the [<key len>] option from CMODE command as the cipher
2077 name decides the key length, nowadays. See the defined ciphers
2078 from the protocol specification.
2080 * Added [<hmac>] option to the CMODE command to define the HMAC
2081 for the channel. Added SILC_CMODE_HMAC channel mode.
2083 * Added [<hmac>] option for the JOIN command so that user can
2084 select which HMAC is used to compute the MACs of the channel
2087 * Added Hmac field to the Channel Message Payload. The integrity
2088 of plaintext channel messages are now protected by computing
2089 MAC of the message and attaching the MAC to the payload. The
2090 MAC is encrypted. Now, it is clear that this causes some
2091 overhead to the size of the packet but rationale for this is that
2092 now the receiver can verify whether the channel message decrypted
2093 correctly and also when private keys are set for the channel the
2094 receiver can decrypt the packet with several keys and check from
2095 the MAC which key decrypted the message correctly.
2097 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2098 lib/silccrypt/silccipher.[ch].
2100 * Added silc_hash_len to return the digest length into the
2101 lib/silcrypt/silchash.[ch].
2103 * Rewrote parts of Silc Channel Payload interface in the
2104 lib/silccore/silcchannel.[ch]. The encode function now also
2105 encrypts the packet and parse function decrypts it.
2107 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Fixed a minor formatting bug in the SKE's key material processing.
2110 It actually might have processed the keys wrong way resulting
2113 * Redefined the mandatory HMAC algorithms and added new algorithms.
2114 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2115 and hmac-md5 truncated to 96 bits. The mandatory is now
2116 hmac-sha1-96. Rest are optional (including the one that used
2117 to be mandatory). Rationale for this is that the truncated HMAC
2118 length is sufficient from security point of view and can actually
2119 make the attack against the HMAC harder. Also, the truncated
2120 HMAC causes less overhead to the packets. See the RFC2104 for
2123 * Added new [hmac] configuration section. The SKE used to use
2124 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2125 is of course wrong. The official names that must be proposed in
2126 the SKE are the ones defined in the protocol specification
2127 (hmac-sha1-96 for example). The user can configure any hmac
2128 using any hash function configured in the [hash] section. At
2129 least, the mandatory must be configured.
2131 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2133 * Added HMAC list to the SKE proposal list. It has now both
2134 hash algorithm list and HMAC list. This makes the protocol
2135 incompatible with previous versions. The SKE now seems to work
2136 the way it is supposed to work, for the first time actually.
2138 * Defined plain Hash algorithms to the protocol specification.
2141 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Implemented support for key agreement packets into the server.
2144 Added functions silc_server_key_agreement and
2145 silc_server_send_key_agreement. Other than these functions,
2146 server has nothing to do with this packet.
2148 * Added support for private message key packets into the server.
2149 Added functions silc_server_private_message_key and
2150 silc_server_send_private_message_key.
2154 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2155 called in the protocol's final callback instead in the END
2156 protocol state. This makes a little more sense and in the same
2157 time in client we can use the same protocol routines for normal
2158 key exchange and to key agreement packet handling as well.
2160 * Added to both client's and server's KE protocol context the
2161 SilcSKEKeyMaterial pointer to save the key material. We will
2162 bring the key material to the protocol's final callback by doing
2163 this. The final callback must free the key material.
2165 * Added SKE's packet_send callback into client's KE protocol
2166 context so that the caller can choose what packet sending function
2167 is used. This way we can use different packet sending when
2168 doing normal SKE when doing key agreement packet handling (in
2169 the key agreement packet handling we do not want to encrypt
2172 * Implemented the responder side of the key agreement routines
2173 in the client. The client can now bind to specified port and
2174 accept incoming key negotiation. The key material is passed
2175 to the application after the protocol is over.
2177 * Implemented the processing of incoming Key Agreement packet
2178 in the client. Added function silc_client_key_agreement to
2181 * Implemented the intiator side of the key agreement routines
2182 in the client. The client can now initiate key agreement with
2183 another remote client. The key material is passed to the
2184 application after the protocol is over.
2186 * Created client_keyagr.c to include all the key agreement
2189 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2190 SILC_TASK_CALLBACK except that it is not static.
2192 * Created client_notify.c and moved the Notify packet handling
2193 from the client.[ch] into that file.
2195 * Created client_prvmsg.c and moved all private message and
2196 private message key routines from the client.[ch] into that file.
2198 * Create client_channel.c and moved all channel message and
2199 channel private key routines from the client.[ch] into that file.
2201 * Changed silc_client_get_client_by_id_resolve to resolve with
2202 WHOIS command instead of IDENTIFY command, in the file
2203 lib/silclient/idlist.c.
2205 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Implemented the SKE's responder side to the Client library.
2209 * When FAILURE is received to the protocol do not trust it
2210 blindly. Register a timeout to wait whether the remote closes
2211 the connection as it should do it, only after that process the
2212 actual failure. This was changed to both client and server.
2214 * Added client_internal.h to include some of the structures
2215 there instead of client.h in lib/silcclient/.
2217 * Added function silc_task_unregister_by_callback to unregister
2218 timeouts by the callback function.
2220 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Some "Incomplete WHOIS info" errors has been appearing on the
2223 log files. Took away the entry->userinfo check from WHOIS
2224 reply sending. The entry->userinfo is now " " if client did not
2225 provide one. I thought this was fixed earlier but something
2226 is wrong still. Let's see if the error still appears.
2228 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Fixed a minor bug in the login when the channel key is
2231 re-generated in the server. It used to generate the key in
2232 wrong order and thus caused problems in the channel traffic.
2234 * Fixed a minor bug in channel key distsribution after
2235 KICK command. The key was not sent to the router even though
2238 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Added silc_ske_process_key_material_data as generic routine
2241 to process any key material as the SILC protocol dictates. The
2242 function is used by the actual SKE library but can be used by
2243 applications as well. This relates to the private message keys
2244 and the channel private keys since they must be processed the
2245 same way the normal SILC session keys. The protocol dictates
2246 this. Affected files: lib/silcske/silcske.[ch].
2248 Added also silc_ske_free_key_material to free the
2249 SilcSKEKeyMaterial structure.
2251 * Defined silc_cipher_set_key function to set the key for
2252 cipher without using the object's method function. The affected
2253 files: lib/silccrypt/silccipher.[ch].
2255 * Implemented silc silc_client_add_private_message_key,
2256 silc_client_add_private_message_key_ske,
2257 silc_client_del_private_message_key,
2258 silc_client_list_private_message_keys and
2259 silc_client_free_private_message_keys functions in the
2262 Added functions silc_client_send_private_message_key to send
2263 the Private Message Key payload and silc_client_private_message_key
2264 to handle incoming Private Message Key payload.
2266 * Added Cipher field to the Private Message Key payload to set
2267 the cipher to be used. If ignored, the default cipher defined
2268 in the SILC protocol (aes-256-cbc) is used.
2270 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2272 * Removed lib/silcclient/ops.h file.
2274 Redefined parts of the SILC Client Library API. Created new
2275 file silcapi.h that deprecates the ops.h file and defines the
2276 published Client Library API. Defined also private message key
2277 API and channel private key API into the file.
2279 This is the file that the application must include from the
2280 SILC Client Library. Other files need not be included by
2281 the application anymore.
2283 * Added new key_agreement client operation callback and also
2284 defined the Key Agreement library API for the application.
2286 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2289 is used by clients to request key negotiation between another
2290 client in the SILC network. If the negotiation is started it
2291 is performed using the SKE protocol. The result of the
2292 negotiation, the secret key material, can be used for example
2293 as private message key.
2295 Implemented the Key Agreement payload into the files
2296 lib/silccore/silauth.[ch].
2298 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * Redefined ciphers for the SILC protocol. Added some new ciphers
2301 and defined the key lengths for the algorithms. Changed the
2302 code accordingly. The default key length is now 256 bits.
2304 * Fixed SKE key distribution function silc_ske_process_key_material
2305 when the key length is more than 128 bits. The default key
2306 length in SILC is now 256 bits.
2308 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2309 to indicate unsupported algorithm.
2311 * Renamed rijndael.c to aes.c and all functions as well.
2313 * Fixed a long standing channel key setting bug in client library.
2314 Weird that it has never surfaced before.
2316 * Fixed bug in channel deletion. If the entire channel is removed
2317 then it must also delete the references of the channel entry
2318 from the client's channel list as the client's channel entry and
2319 the channel's client entry share same memory.
2321 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Implemented CONNECT and SHUTDOWN commands in the client.
2325 * Implemented CLOSE command to the client.
2327 * Added the function silc_idlist_find_server_by_name into the
2328 files silcd/idlist.[ch].
2330 Added the function silc_idlist_find_server_by_conn into the
2331 files silcd/idlist.[ch].
2333 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * DIE command was renamed to SHUTDOWN. Updated the both code
2338 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2339 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2341 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2344 * Added function silc_server_create_connection function to create
2345 connection to remote router. My server implementation actually
2346 does not allow router to connect to normal server (it expects
2347 that normal server always initiates the connection to the router)
2348 so the CONNECT command is only good for connecting to another
2351 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2354 or some other client was kicked from the channel.
2356 Implemented the handling of the notify type to both client
2359 Implemented silc_server_send_notify_kicked to send the KICKED
2360 notify. It is used to send it to the server's primary router.
2362 * Implemented the KICK command into server and client.
2364 * Added `query' argument to the silc_idlist_get_client function
2365 to indicate whether to query the client from server or not if
2368 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2369 to indicate that the client is not channel founder.
2373 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Removed the rng context from SilcPacketContext structure and
2376 changed that the packet routine uses the Global RNG API.
2378 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2380 * Added support for quit message that client can "leave" on the
2381 channel when it quits the SILC. It is ditributed inside the
2382 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2384 Added silc_server_free_client_data that will take the
2385 signoff message as argument.
2387 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2389 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2391 * Updated parts of the protocol specification to keep it up
2394 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2397 payloads in one packet.
2399 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2400 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2401 use now the new List flag.
2403 * Also deprecated the following packet types: REPLACE_ID,
2404 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2406 * Added list support for Notify packet in server.
2408 * Added silc_server_send_notify_channel_change to send the
2409 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2410 the silc_server_send_replace_id.
2412 * Added silc_server_send_notify_nick_change to send the
2413 NICK_CHANGE notify type. Deprecates the function
2414 silc_server_send_replace_id.
2416 * Added silc_server_send_notify_join to send the JOIN notify type.
2417 Deprecates the function silc_server_send_new_channel_user.
2419 * Added silc_server_send_notify_leave to send LEAVE notify type.
2420 Deprecates the function silc_server_send_remove_channel_user.
2422 * Added silc_server_send_notify_cmode and
2423 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2424 types. Deprecates the silc_server_send_set_mode function.
2426 * Added SERVER_SIGNOFF notify type to indicate that server has
2427 quit. This means that all clients on the channel from that
2428 server will drop. This can be also used when netsplit happens.
2430 Deprecated REMOVE_ID packet type since it is not needed anymore
2433 Added silc_server_send_notify_server_signoff to send the
2434 SERVER_SIGNOFF notify type. Deprecates the function
2435 silc_server_send_remove_id.
2437 Added also silc_server_send_notify_signoff to send the
2438 SIGNOFF notify type.
2440 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2441 SILC protocol from this day on. Changed the protocol
2442 specification as well.
2444 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2445 notify type. It is used between routers to notify about
2446 topic changes on a channel.
2448 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2451 * Partly updated the protocol specification to comply with the
2452 changes now made. It is still though a bit outdated.
2454 * The JOIN notify type now takes one extra argument <Channel ID>.
2455 The packet used to be destined to the channel but now the
2456 JOIN type may be sent as list thus it is impossible to
2457 destine it to any specific channel. By adding this argument
2458 it is again possible.
2460 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Added CREDITS file. The CHANGES and CREDITS file will appear
2463 in the distribution as well.
2465 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2468 types in the server's silcd/packet_receive.c.
2470 * Implemented CMODE and CUMODE to work in router environment.
2472 * Fixed minor encoding and decoding buglet from the
2473 lib/silccore/silcmode.c.
2475 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2478 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2480 * Changed all SilcConfigServer* and silc_config_server* to
2481 SilcServerConfig* and silc_server_config*, respectively.
2484 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Associated the ID (client or server ID) to the Authentication
2487 Payload to avoid any possibility of forging. Updated the
2488 protocol specification and the code accordingly.
2490 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * The RSA key length is now save to the RsaKey context in the
2493 key generation process in lib/silccrypt/rsa.c. The key length
2494 is now used to figure out the maximum size of the block allowed
2495 to be encrypted/signed.
2497 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2498 is equivalent to the silc_mp_mp2bin but does not allocate any
2501 * Changed silc_mp_mp2bin API to take length argument. If it is
2502 non-zero then the buffer is allocated that large. If zero, then
2503 the size is approximated using silc_mp_sizeinbase, which however
2506 * Created Global RNG API which is global RNG that application can
2507 initialize. After initializing, any routine anywhere in the
2508 code (including library) can use RNG without allocating a new
2509 RNG object. This was done to allow this sort of use of the
2510 RNG in code that has no chance to allocate RNG object. All
2511 applications currently allocate this and many routines in the
2512 library use this. Affected file lib/silccrypt/silcrng.[ch].
2514 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2515 it to use the Global RNG API.
2517 * Defined Authentication Payload into protocol specification that
2518 is used during SILC session to authenticate entities. It is
2519 used for example by client to authenticate itself to the server
2520 to obtain server operator privileges.
2522 Implemented this payload into the lib/silccore/silcauth.[ch].
2523 Implemented also routines for public key based authentication
2524 as the new protocol specification dictates.
2526 Moved definitions of different authentication methods from
2527 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2529 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2530 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2531 silc_pkcs_verify_with_hash functions into the file
2532 lib/silccrypt/silcpkcs.[ch].
2534 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * The client entry's userinfo pointer must be always valid.
2537 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2538 will fail since it requires the userinfo. Now, the userinfo
2539 is allocated as "" if actual userinfo does not exist. Actually,
2540 it must exist and it is totally Ok to drop client connections
2541 that does not announce the userinfo. However, we will make
2542 this workaround for now.
2544 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2545 to return the remote port by socket.
2547 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2550 SILC_SERVER_PENDING_EXEC and added an new macro
2551 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2552 data or when error occurs while processing the pending command.
2554 Added new argument `destructor' into silc_server_command_pending
2555 and to the SilcServerCommandPending object. This destructor is
2556 now called after calling the pending callback or if error occurs
2557 immediately. If error occurs the actual pending callback won't
2558 be called at all - only the destructor. The destructor may be
2559 NULL if destructor is not needed.
2561 All this applies for client library code as well. Similar
2562 changes were made there as well for the pending commands.
2564 In the client, the application must now allocate the
2565 SilcClientCommandContext with the silc_client_command_alloc
2568 * Added reference counter to the SilcServerCommandContext. Added
2569 function silc_server_command_alloc and silc_server_command_dup
2572 Same type of functions added to the client library for the same
2575 * Removed the cmd_ident from IDListData away since it is now
2576 global for all connections. It is the command identifier used
2577 in command sending and with pending commands. The affected file
2580 * Added reference counter to the SilcSocketConnection objecet to
2581 indicate the usage count of the object. The object won't be
2582 freed untill the reference counter hits zero. Currently only
2583 server uses this, and client ignores it. The client must be
2584 set to use this too later. The affected files are
2585 lib/silccore/silcsockconn.[ch]. Added also the function
2586 silc_socket_dup to increase the reference counter.
2588 This was mainly added because it is possible that the socket
2589 is removed underneath of pending command or other async
2590 operation. Now it won't be free'd and proper DISCONNECTING
2591 flags, etc. can be set to avoid sending data to connection that
2592 is not valid anymore.
2594 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2595 the connection. After that it sets SILC_SET_DISCONNECTED.
2596 It is, however, possible that the socket data is not still freed.
2597 The silc_server_packet_process now checks that data is not
2598 read or written to connection that is DISCONNECTED. The socket
2599 get's freed when the reference counter hits zero.
2601 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Changed the client operation API: channel_message operation's
2604 `sender' is now the client entry of the sender, not the nickname
2605 and the `channel' is the channel entry, not the channel name.
2607 In the private_message operation the `sender' is now also the
2608 client entry of the sender not the nickname.
2610 Affected file is lib/silcclient/ops.h and all applications
2611 using the client operations.
2613 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Moved the calling of ops->connect() from connect_to_server_final
2616 into receive_new_id functin since that is the point when the
2617 client is actually allowed to send traffic to network. The
2618 affected file is lib/silcclient/client.c.
2620 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2623 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2624 (if needs broadcasting) instead of broadcasting the packets one
2625 by one which would make a burst in the network traffic.
2627 * Added `broadcast' argument to the functions in silcd/server.[ch]
2628 silc_server_create_new_channel[_with_id] to indicate whether
2629 to send New Channel packet to primary router.
2631 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Added new function into the silcd/server.[ch] files:
2634 silc_server_create_new_channel_with_id to create new channel with
2635 already existing Channel ID.
2637 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2638 lib/silccore/silcpacket.h. This packet is used t send list of
2639 Set Mode payloads inside one packet. Server uses this to set
2640 the modes for the channels and clients on those channels, that it
2641 announced to the router when it connected to it. The protocol
2642 specification has been updated accordingly.
2644 * The silc_server_new_channel did not handle the packet coming
2645 from normal server as it normally does not send that. However,
2646 when it announces its channels it does send it. Implemented
2647 the support for that.
2649 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2650 into the file lib/silccore/id.h.
2652 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Fixed memory leaks in the functions silc_idlist_del_client,
2655 silc_idlist_del_channel and silc_idlist_del_server in the file
2656 silcd/idlist.c. All of those leaked like a sieve.
2658 * Fixed some small memory leaks in the client's function
2659 silc_client_notify_by_server.
2661 * Added functions into silcd/server.c: silc_server_announce_clients,
2662 silc_server_announce_channels and silc_server_announce_server.
2663 These functions are used by normal and router server to announce
2664 to its primary router about clients, channels and servers (when
2665 router) that we own. This is done after we've connected to the
2668 These functions effectively implements the following packet types:
2669 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2670 and SILC_PACKET_NEW_ID_LIST.
2672 * Added new functions into the silcd/packet_receive.[ch]:
2673 silc_server_new_id_list, silc_server_new_channel_list and
2674 silc_server_new_channel_user_list to handle the incoming
2675 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2677 * Added support of changing Channel ID in the function
2678 silc_server_replace_id. If the server that announces a channel
2679 to the router already exists in the router (with same name but
2680 with different Channel ID), router is responsible to send
2681 Replace ID packet to the server and force the server to change
2682 the Channel ID to the one router has.
2684 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2685 client that the Channel ID has been changed by the router. The
2686 normal server sends this to the client. Client must start using
2687 the new Channel ID as the channel's ID.
2689 Implemented handling of this new type into lib/silcclient/client.c
2690 into the function silc_client_notify_by_server.
2692 * Added new function silc_idlist_replace_channel_id into the files
2693 silcd/idlist.[ch] to replace the Channel ID.
2695 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Call silc_server_command_identify_check always when processing
2698 the IDENTIFY command in silcd/command.c
2700 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2703 send keepalive packets. The packet can be sent by clients,
2704 servers and routers.
2706 Added function silc_socket_set_heartbeat into the file
2707 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2708 If not set, the heartbeat is not performed. The actual
2709 heartbeat is implemented in the low level socket connection
2710 library. However, application is responsible of actually
2713 Added silc_server_send_heartbeat to send the actual heartbeat
2714 packet into silcd/packet_send.[ch]. Server now performs
2715 keepalive with all connections.
2717 * Added silc_task_get_first function into lib/silcutil/silctask.c
2718 to return the timeout task with shortest timeout. There was a bug
2719 in task unregistration that caused problems. TODO has been
2720 updated to include that task system must be rewritten.
2722 * The client library will now resolve the client information when
2723 receiving JOIN notify from server for client that we know but
2724 have incomplete information.
2726 * Rewrote parts of silc_server_remove_from_channels and
2727 silc_server_remove_from_one_channel as they did not remove the
2728 channel in some circumstances even though they should've.
2730 * Encryption problem encountered in server:
2732 The LEAVE command used to send the Channel Key packet to the
2733 router immediately after generating it. However, the code
2734 had earlier sent Remove Channel user packet but not immediately,
2735 ie. it was put to queue. The order of packets in the router
2736 was that Channel Key packet was first and Remove Channel User
2737 packet was second, even though they were encrypted in the
2738 reverse order. For this reason, MAC check failed. Now, this
2739 is fixed by not sending the Channel Key packet immediately but
2740 putting it to queue. However, this is more fundamental problem:
2741 packets that are in queue should actually not be encrypted
2742 because packets that are sent immediately gets encrypted
2743 actually with wrong IV (and thus MAC check fails). So, packets
2744 that are in queue should be encrypted when they are sent to
2745 the wire and not when they put to the queue.
2747 However, the problem is that the current system has not been
2748 designed to work that way. Instead, the packet is encrypted
2749 as soon as possible and left to the queue. The queue is then
2750 just purged into wire. There won't be any fixes for this
2751 any time soon. So, the current semantic for packet sending
2754 o If you send packet to remote host and do not force the send
2755 (the packet will be in queue) then all subsequent packets to the
2756 same remote host must also be put to the queue. Only after the
2757 queue has been purged is it safe again to force the packet
2760 o If you send all packets immediately then it safe to send
2761 any of subsequent packets through the queue, however, after
2762 the first packet is put to queue then any subsequent packets
2763 must also be put to the queue.
2765 Follow these rules and everything works fine.
2767 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Added new function silc_server_remove_clients_by_server to
2770 remove all client entries from ID list when the server connection
2771 is lost. In this case it is also important to invalidate all
2772 client entires as they hold the invalid server entry. This
2773 fixes fatal bug when server has lost connection and will reconnect
2776 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Made some sanity checks to silc_server_daemonise like to check
2779 whether the requested user and group actually exists.
2781 * Added sanity check to SKE's silc_ske_responder_finish to check
2782 that the public and private key actually is valid.
2784 * Invalidate the client's nickname when receiving Replace ID
2785 packet and the Client ID is being replaced. This means that the
2786 server will query the nickname if someone needs it (client)
2789 * Sort the ID Cache in client library when the ID Cache data
2790 has changed (needs sorting).
2792 * Do not allow for SILC client to create several connections to
2793 several servers. The client does not support windows right now
2794 and generating multiple connections causes weird behaviour.
2796 Irssi-silc client does support windows and can handle several
2797 connections without problems, see: www.irssi.org and SILC plugin.
2799 * Fixed some places where client was added to the IDList. The
2800 rule of thumb is following (in order to get everything right):
2801 If the client is directly connected local client then the
2802 `connection' argument must be set and `router' argument must be
2803 NULL to silc_idlist_add_client function. If the client is not
2804 directly connected client then the `router' argument must
2805 bet set and the `connection' argument must be NULL to the
2806 silc_idlist_add_client function.
2808 * The funtion silc_server_packet_send_local_channel actually did
2809 not check whether the client was locally connected or not. It
2810 does that now. Fixed a bug related to LEAVE command.
2812 * Fixed Remove Channel User payload parsing bug in server's
2813 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2815 * The server's silc_server_save_channel_key now checks also the
2816 global ID list for the channel as it might not be in the local
2817 list. Fixed a bug related to LEAVE command.
2819 * Is this the end of the [<unknown>] buglet that has been lurking
2820 around for a long time? A little for loop fix in server's
2821 silc_server_command_whois_parse that is used by both IDENTIFY
2822 and WHOIS command. At least, this was a clear bug and a cause
2823 of one type of [<unknown>] buglet.
2825 * WHOIS and IDENTIFY commands call the function
2826 silc_server_command_[whois/identify]_check function even if
2827 we are not router server.
2829 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Added --with-gmp configuration option. If set the GMP
2832 is always compiled in the SILC source tree. If not set then
2833 it is checked whether the system has the GMP3 installed. If
2834 it has then the GMP won't be compiled (the system's headers
2835 and library is used), if it doesn't have it then the GMP is
2836 compiled in the SILC source tree.
2838 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Changed RSA private exponent generation to what PKCS #1
2841 suggests. We try to find the smallest possible d by doing
2842 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2843 not security fix but optimization.
2845 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Added new config entry [Identity] to fork the server and run
2848 it as specific user and group. A patch from Bostik.
2850 * Imported Dotconf configuration library into lib/dotconf.
2851 This will be used to create the SILC configuration files later.
2852 It will appear in the distsribution after this commit.
2854 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * A big code auditing weekend happening. Auditing code for
2857 obvious mistakes, bugs and errors. Also, removing any code
2860 Removed files for being obsolete:
2862 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2863 inline in the file lib/silcutil/silcbuffer.h)
2865 o lib/silcutil/silcbufutil.c (the header has inline versions)
2867 Changed code to fix possible error conditions:
2869 o The buffer formatting routines now check that the destination
2870 buffer really has enough space to add the data. This applies for
2871 both buffer formatting and unformatting
2872 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2873 unformatting was changed to accomodate following rules:
2874 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2875 sent to the function while XXX_*STRING will not allocate or copy
2876 the data into the buffer. Instead it sets the pointer from the
2877 buffer into the pointer sent as argument (XXX_*STRING used to
2878 require that the pointer must be allocated already). This change
2879 makes this whole thing a bit more consistent and more optimized
2880 (note that the data returned in the unformatting with XXX_*STRING
2881 must not be freed now). The routines return now -1 on error.
2883 o Tried to find all code that use buffer_format and buffer_unformat
2884 and added return value checking to prevent formatting and
2885 especially unformatting errors and possible subsequent fatal
2888 o Changed ske->x and ske->KEY to mallocated pointers in
2889 lib/silcske/silcske.h. Fixed possible data and memory leak.
2891 o Added return value checking to all *_parse* functions. Fixed
2892 many memory leaks as well.
2894 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2895 so that buffer overflows would not happen. All code now also
2896 checks the return value as it can fail.
2898 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Added reconnection support to server if the normal server looses
2901 its connection to the router (for example if router is rebooted).
2902 The server performs normal reconnection strategy implemented
2903 to the server. Affected file silcd/server.c.
2905 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Added new packet type SILC_PACKET_SET_MODE that is used to
2908 distribute the information about changed modes (for clients,
2909 channels and clients channel modes) to all routers in the
2910 network. Updated the protocol specification accordingly.
2912 Added functions into silcd/packet_send.c and
2913 silcd/packet_receive.c: silc_server_send_set_mode,
2914 silc_server_set_mode.
2916 Added new files silcmode.[ch] into lib/silccore that implements
2917 the encoding and decoding of Set Mode Payload. Added new type
2918 SilcSetModePayload. Moved the definitions of different modes
2919 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2921 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Oops, a little mistake in server's connection authentication
2924 protocol. The protocol is not ended with FAILURE but with
2925 SUCCESS if the authentication is Ok. :) Affected file is
2928 * Implemented NICK_CHANGE notify handling in server in the file
2929 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2930 the local clients on the channel. After the changing nickname
2931 in router environment snhould work and the [<unknown>] nickname
2932 should appear no more.
2934 The silc_server_replace_id function that receives the Replace ID
2935 payload now sends the NICK_CHANGE notify type also in the file
2936 silcd/packet_receive.c
2938 * Changed WHOIS and IDENTIFY command to support the maximum amount
2939 of arguments defined in protocol specs (3328 arguments). This
2940 fixed a bug that caused problems when there were more than three
2943 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Added extra parameter, command identifier, to the
2946 silc_client_send_command so that explicit command identifier
2949 Changed that ID list routines uses specific command identifier
2950 when sending WHOIS/IDENTIFY requests to the server so that they
2951 can be identified when the reply comes back.
2953 Affected files lib/silcclient/command.[ch],
2954 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2956 * Added `sender' argument to silc_server_packet_send_to_channel
2957 to indicaet the sender who originally sent the packet to us
2958 that we are now re-sending. Ignored if NULL. Affected file
2959 silcd/packet_send.[ch].
2961 * Added some server statistics support in silcd/server_internal.h
2962 SilcServerStatistics structure and around the server code. Also
2963 send some nice statistics information when client is connecting
2966 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Fixed channel ID decoding in server's JOIN command reply in
2969 silcd/command_reply.c
2971 * Fixed braodcasting of replace ID payload to not to send it if
2972 we are standalone server in silcd/packet_receive.c.
2974 * Fixed all channel message sending routines to not to send
2975 packets to clients that has router set, since they are routed
2976 separately in the same function earlier. Affects file
2977 silcd/packet_send.c and all channel packet sending functions.
2979 * In USERS reply, res_argv[i] are not allocated, the table
2980 is allocated. Thus changed that free the table, not its
2983 * In server's whois_check and identify_check if the client is
2984 locally connected do not send any WHOIS commands - they are not
2987 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Fixed some minor bugs in client when sending WHOIS command. The
2990 arguments was in wrong order.
2992 * Removed statis function add_to_channel from server in
2993 silcd/command.c that was previously used with the joining but
2996 * Tested USERS command in router environment successfully with two
2997 routers, two servers and two clients.
2999 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Reorganized the USERS command and command reply in client library
3002 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3003 When the command is given by user we register a pending command
3004 callback that will reprocess the command after the reply has been
3005 received from the server. When reprocessing the packet we then
3006 display the information. Thus, the USERS information is displayed
3007 now in the command callback instead of in the command reply
3008 callback. The processing of the command is same as previously
3009 when server has sent the command reply in the JOINing process.
3011 * Added to USERS command in silcd/command_reply.c to join the client,
3012 we didn't use to know about, to the channel after we've created
3013 a client entry for it. Also, for clienet we did know already still
3014 check whether it is on the channel or not and add it if not.
3016 * Removed silc_server_command_join_notify as the function and its
3019 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Changed the client's pending command handling to the same as the
3022 server's pending command handling. It is also now possible to
3023 execute command reply functions from other command reply
3024 function as the function callbacks for commands and command
3025 replies are one and same. The pending commands are not static
3026 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3027 in client connection context. Thus, pending commands are server
3028 connection specific as it is convenient.
3030 Changed the function silc_client_command_pending and
3031 silc_client_command_pending_del and added new function
3032 silc_client_command_pending_check. Removed the
3033 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3036 * Added cmd_ident, current command identifier, to the client
3037 connection context in lib/silcclient/client.h to keep track on
3038 command identifiers used in command sending. Client's command reply
3039 function handling now supports the mandatory command identifiers.
3041 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3042 funtions in client to fully support pending command callbacks.
3044 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3045 as one of the arguments to the application in the command reply
3048 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3049 before first releasing SILC but came back. Now it is removed again
3050 and should come back nomore. The FORWARDED flag was used only
3051 by the JOINing procedure by forwarding the command packet to router.
3052 Now, the JOINing procedure has been changed to more generic (due
3053 to various router environment issues) and FORWARDED is not needed
3054 anymore for anything. The protocol specification is yet to be
3057 Now, removed silc_server_packet_forward from server and the flag
3058 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3060 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Renamed NAMES command to USERS command. The NAMES was named that
3063 due to historical reasons. Now it is renamed. Also, rewrote
3064 parts of the USERS command. The nickname list is not sent anymore
3065 by the server. Only Client ID and mode lists are sent in the USERS
3066 command. Changed this also to the protocol specification.
3068 The client now resolves the names and stuff after it receives
3069 the USERS list from the server when joining to the channel.
3071 * WHOIS and IDENTIFY commands has been changed to support multiple
3072 Client ID's per command. One can now search for multiple users
3073 in the network by sending only one WHOIS or IDENTIFY command.
3074 Changed the code and the protocol specifications.
3076 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3077 uses silc_server_command_whois_parse to parse the request. */
3079 * If normal server, do not parse the WHOIS and IDENTIFY requests
3080 before sending it to the router. Saves some time.
3082 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Fixed JOIN command on client library. Wrong number of arguments
3085 used to crash the client.
3087 * Added silc_server_channel_has_global function to check whether
3088 channel has global users or not.
3090 * Added silc_server_channel_has_local function to check whether channel
3091 has locally connected clients on the channel.
3093 * The silc_server_remove_from_one_channel now checks whether the
3094 channel has global users or not after given client was removed from
3095 the channel. It also checks whether the channel has local clients
3096 on the channel anymore. If it does not have then the channel entry
3097 is removed as it is not needed anymore.
3099 * The silc_server_notify now checks on JOIN notify whether the joining
3100 client is one of locally connected or global. If it is global then
3101 the channel has now global users on the channel and that is marked
3102 to the channel entry. Also, it now saves the global client to
3103 global list who is joining and JOINs it to the channel. This is
3104 for normal server, that is.
3106 Changed silc_server_send_notify_on_channel,
3107 silc_server_packet_relay_to_channel and
3108 silc_server_packet_send_to_channel check if we are normal server
3109 and client has router set (ie. global client) do not send the
3110 message to that client, as it is already routed to our router.
3112 * Implemented LEAVE notify type handling in silc_server_notify
3115 * Tested LEAVE command in router environment successfully. Tested
3116 with two routers, two servers and two clients.
3120 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3122 * Implemented SIGNOFF notify type handling in silc_server_notify
3125 * silc_server_remove_id now removes the client entry from all channels
3126 it has joined and thusly sends SIGNOFF notify type.
3128 * Rewrote the NAMES list generation in server by removing two excess
3129 loops. The lists are created now inside one loop.
3131 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * silc_server_remove_channel_user checks now also global list
3134 for channel and client.
3136 * silc_server_new_channel_user checks now both local and global
3137 list for channel and client. Fixed a bug in client id decoding.
3138 Used to decode wrong buffer.
3140 * silc_server_channel_message checks now both local and global
3141 list for channel entry.
3143 * Tested channel joining (hence JOIN) in router environment
3144 successfully. Tested with two routers, two servers and two
3147 * Tested channel message sending in router environment successfully.
3149 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Added silc_server_save_channel_key into server.[ch] to save the
3152 received channel key in Channel Key payload processing. It is
3153 also used in JOIN command reply handling.
3155 Equivalent function silc_client_save_channel_key added into
3156 client.[ch] into client library.
3158 * Changed JOIN command reply to send information whether the channel
3159 was created or not (is existing already) and the channel key
3160 payload. Changed protocol specs accordingly.
3162 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3163 the request was sent by ID and not by nickname. Crashed on
3166 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3169 now correctly save the received data.
3171 * silc_server_free_sock_user_data now notifies routers in the
3172 network about entities leaving the network.
3174 At the same time implemented functions silc_server_remove_id
3175 and silc_server_send_remove_id to receive and send REMOVE_ID
3176 packets. The packet is used to notify routers in the network
3177 about leaving entities. The ID removed will become invalid in
3180 * Added function silc_idlist_del_server into server. Removes and
3181 free's server entry from ID list.
3183 * silc_server_private_message function now checks, if we are router,
3184 that the destination ID really is valid ID, naturally.
3186 * In router when NEW_ID packet is received (for new client) the
3187 hash of the Client ID is saved in the ID Cache but the
3188 client->nickname is set to NULL, instead of putting the hash
3191 IDENTIFY command now also checks that client->nickname must be
3192 valid. If it is not if will request the data from the server who
3193 owns the client. Added new function
3194 silc_server_command_identify_check.
3196 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3197 to set the command to already allocated Command Payload.
3199 * Tested private message sending in router environment with two
3200 routers, two servers and two clients. Fixed minor bugs and now
3203 * Fixed segfault from client's NAMES command. Used to crash if
3206 * Forwarded packets must not be routed even if it is not destined
3207 to the receiver. Changed server code comply with this.
3209 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Added `require_reverse_mapping' boolean value to ServerParams
3212 structure. If TRUE (not default) the server will require that
3213 the connecting host has fully qualified domain name.
3215 If the reverse mapping is not required and hostname could not be
3216 found the IP address is used as hostname.
3218 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Implemented version string checking to both client and server.
3221 The check is incomplete currently due to the abnormal version
3222 strings used in development version of SILC.
3224 * Changed all command functions in server to use the new
3227 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Changed char *data to unsigned char *data in ID Cache system to
3230 support binary data as ID Cache data. Changed code to support
3231 binary data in lib/silccore/idcache.c.
3233 * Renamed silc_server_packet_relay_command_reply to
3234 silc_server_command_reply as it is normal packet receiving
3235 function. Rewrote the function to accept command replys for
3236 servers and not only for clients.
3238 * Mark remote router always as registered server if we are connecting
3239 to it. Otherwise, commands sent by the router to us are ignored.
3241 * All ID List find routines now returns the ID Cache Entry pointer
3242 as well if requested.
3244 * WHOIS command works now in router environment, tested with two
3245 routers, two servers and two clients.
3247 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3248 in router environment (as it is almost equivalent to WHOIS) but
3249 hasn't been tested thoroughly. Added new functions:
3251 silc_server_command_identify_parse
3252 silc_server_command_identify_send_reply
3253 silc_server_command_identify_from_client
3254 silc_server_command_identify_from_server
3256 * Disabled route cache adding because adding two different ID's with
3257 same IP replaces the old cache entry thus giving wrong route.
3258 The entry->router->connection is always the fastest route anyway
3259 so route cache may not be needed. Of course, new routes maybe
3260 established after receiving the ID when the entry->router->connection
3261 might not be anymore the most optimal.
3263 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Add route cache for received ID for fast routing.
3267 * Added silc_server_packet_route to route received packet on router
3268 that is not destined to us.
3270 * Renamed silc_server_get_route to silc_server_route_get.
3272 * Added id_string and id_string_len fields into SilcServer to
3273 include encoded ServerID for fast comparing without excess
3274 encoding of the ID's.
3276 * Cleaned up WHOIS command on server side. Added following static
3279 silc_server_command_whois_parse
3280 silc_server_command_whois_check
3281 silc_server_command_whois_send_reply
3282 silc_server_command_whois_from_client
3283 silc_server_command_whois_from_server
3285 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3286 arguments in command replies. All command functions should be
3287 updated to use this macro.
3289 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Minor typo fixes on command reply handling on server.
3293 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Added silc_server_command_add_to_channel internal routine to add
3296 the client to the channel after router has created the channel and
3297 sent command reply to the server.
3299 * Added generic silc_server_send_command to send any command from
3302 * Use static buffer with ID rendering instead of duplicating data.
3304 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Fixed a channel user mode bug when joining to a channel server gave
3307 everybody channel founder rights, oops.
3309 * We mark ourselves as the router of the incoming server connection
3310 if we are router ourselves. This way we can check in some packet
3311 sending functions whether it is locally connected server. For
3312 incoming router connections we put NULL.
3314 * For router sending packets locally means now always sending the
3315 packet cell wide; to local clients and local servers. For normal
3316 server sending packet locally means sending it to only local
3319 * Fixed the JOIN command to really work in router environment. If the
3320 channel is created it is always created by the router. Router is
3321 also responsible of making the initial joining to the channel,
3322 sending JOIN notify to the sending server and distributing
3323 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3324 does not exist server doesn't do anything else but forward the
3325 command to the router which performs everything.
3327 * Added silc_server_send_channel_key function to send the Channel Key
3330 * Added silc_server_create_channel_key to create new channel key. The
3331 channel key is now re-generated everytime someone joins or leaves
3332 a channel, as protocol dictates. Note: channel->key_len is the
3335 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3338 packet_receive.[ch] to separate packet sending and receiving
3339 routines. The server.[ch] now includes everything else including
3340 actual packet processing (writing and reading data) and other
3343 Renamed silc_server_private_message_send_internal to
3344 silc_server_send_private_message. The routine is still though
3345 used only to relay private messages as server does not send
3346 private messages itself.
3348 Renamed silc_server_new_channel to silc_server_create_new_channel
3349 and added new function sicl_server_new_channel that handles the
3350 incoming New Channel packet. Added also new sending function
3351 silc_server_send_new_channel to send New Channel Payload.
3353 * Added new function silc_server_notify to process incoming notify
3354 packet to the server/router. Server may then relay the notify
3355 to clients if needed.
3357 * Added new function silc_server_new_channel_user to process incoming
3358 New Channel User packet. Router will redistribute the packet and
3359 send JOIN notify to its local clients and locally connected servers
3360 if needed. Normal server will send JOIN notify to its local client
3361 on same channel when received this packet. Added also corresponding
3362 sending function silc_server_send_new_channel_user to sent the
3365 * Added boolean route argument to send_notif_to_channel and
3366 packet_send_to_channel functions to attempt to route the packet
3367 if it is TRUE and send only locally if it is FALSE.
3369 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * silc_server_replace_id now broadcasts the received replace ID
3372 packet if it is not broadcast packet already. The router must
3373 broadcast to inform other routers about changed ID.
3375 * Added backpointer to server's router into SilcServer context in
3376 silcd/server_internal.h.
3378 * Fixed silc_server_packet_broadcast to send correct broadcast
3381 * The channel key is now distributed to the local client as soon
3382 as it is received from the router (in router environment) so that
3383 no other packet may be sent for the channel until client has
3386 * silc_server_remove_channel_user now broadcasts the received
3387 Remove Channel User packet if it is not broadcast packet already.
3388 The router must broadcast to inform other routers about removed
3391 * Added users field into SilcPacketContext that is a reference count
3392 of the context. One can increase the reference count by calling
3393 silc_packet_context_dup which is now changed to just increase the
3394 reference count instead of duplicating the data. The reference
3395 count is decresed by calling silc_packet_context_free that will
3396 free the data after the reference count hits zero.
3398 For now on the packet context and everything allocated into it
3399 (including the raw packet from network) must be freed by calling
3400 the new silc_packet_context_free function. Added also new function
3401 silc_packet_context_alloc that must be used now to allocate the
3402 context. This also means that if a routine is asynchronous from
3403 silc_[client/server]_packet_parse_type the packet context must
3404 be duplicated by calling silc_packet_context_dup. Otherwise it
3405 gets free'd after silc_[client/server]_packet_parse_type returns.
3406 Also, one must remember that if packet is duplicated then its
3407 reference count must be decresed by calling the free function as
3408 many times as it was duplicated.
3410 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3411 from both client and server.
3413 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Made joining to a channel working in router environment.
3417 * Cleaned up JOIN command on server side and create function
3418 silc_server_command_join_channel internal routine to make the
3421 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Changed silc_command_pending list to SilcDList. Also, added
3424 `ident' field to SilcServerCommandPending structure to identify
3425 the reply and to call correct callback.
3427 Added silc_server_command_pending_check function to replace the
3428 corresnponding macro. The silc_command_pending list is not
3431 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3432 to set identifier to previously allocated Command Payload. It
3433 is used to set identifier for command when resending Command
3436 * Added silc_command_payload_encode_payload to encode Command
3437 Payload buffer from SilcCommandPayload structure.
3439 * Added silc_argument_payload_encode_payload to encode Argument
3440 payload buffer from SilcArgumentPayload structure.
3442 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Changed WHOIS command to support router connection on server side.
3445 The whois request is always sent to router unless the server is
3446 standalone server. After server has received the reply from the
3447 router will it send the reply to the client.
3449 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3450 broadcast received broadcast packet. The function is used only
3451 by router. The broadcast packet is always sent to the router's
3454 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3455 render given ID to printable string, for log files for example.
3457 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Made basic router to router connections working. At least they
3460 can now connect to each other but nothing really works the way
3461 they are supposed - yet.
3463 * Added new initiator token to RouterConnection configuration
3464 file in silcd/serverconfig.[ch]. It is used to tell whether we
3465 are the initiator to the remote router or whether we'll expect
3466 the other end to connect.
3468 * Moved registering of listener task to silc_server_init, hence
3469 the server starts listenning as soon as it is run, even if it
3470 does not have connections to other routers. Let's see how well
3473 * Changed default connection retry timeouts for more suitable in
3476 * Removed cipher and such arguments from silc_idlist_add_client
3477 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3478 Added new function silc_idlist_add_data to add the keys and stuff
3481 * Added SilcIDListData structure and added it to SilcClientEntry
3482 and SilcServerEntry as their first field in the structure. This
3483 way we can explicitly cast the ID entries to the SilcIDListData
3484 structure and get common data for the entries. In past, we had
3485 to first check what type of connection it is and then cast it to
3486 correct ID entry type. Now, we can directly cast the opaque
3487 pointer to the SilcIDListData (no matter what ID entry it actually
3488 is) and get the data needed.
3490 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3493 in some circumstances even if threre were timeout tasks, though not
3494 IO tasks, but tasks anyway. Now fixed.
3496 * Defined SilcServerConnection structure to hold connection specific
3497 stuff about directly connected servers and routers. The definition
3498 is currently in silcd/server_internal.h. I thought about having
3499 a bit more important role fro this struct but for now it is used
3500 only when connecting to other server (or router actually).
3502 * Added connecting retry support in server when connecting to
3503 router(s). The retry feature implement exponential backoff
3504 algorithm. Also, added SilcServerParams structure to hold default
3505 parameters for server. For now, it include these retry settings
3506 and are hard coded. After server is moded to be as Silc Server
3507 Library this structure will be more important.
3509 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Changed client librarys channel->clients table to SilcList and
3512 changed code accordingly.
3514 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Changed client's channel table to SilcList and changed code
3517 accordingly. Also changed SilcChannelClientEntry to include back-
3518 pointer to the channel so that client entry can use that structure
3519 as list as well and we have fast cross-reference to the channel.
3520 This change dramatically decreased the complexity of channel
3521 handling with client entry and vice versa (removed one extra
3522 loop when searching for channel entry from many functions).
3524 * Changed server->sim from table to SilcDList and changed code
3527 * NAMES command can now be used from user interface. It will show
3528 the user list on the channel, neatly.
3530 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3531 Code now saves realname of the user if it becomes available.
3533 * Renamed configure.in to configure.in.pre and made ./prepare
3534 script to automatically add correct version string to
3535 configure.in which it creates from configure.in.pre.
3537 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * NAMES command reply now shows users mode with the nickname when
3542 * Moved silc_client_ch[u]mode[_char] functions from
3543 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3544 place sucks, they are utility functions and should be in some
3547 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3549 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3552 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Added TRQ (efficient deque and list library) into lib/trq. This is
3557 a very good list library that is currently used in the SILC. Defined
3558 SilcList API over the library because I didn't like the API very
3559 much. See lib/trq/silclist.h for the API and examples of how to
3560 use the API. Fixed various places in the code to use the new
3561 SilcList API. The SilcList is meant for lists that has a structure
3562 already defined as a list. It is not suitable to add just some
3563 context to the list (in TRQ, the context is the list actually).
3565 So, I defined SilcDList that can be used for the purpose where
3566 predefined list structure does not exit. This can be used as
3567 such list. Now some context just can be added to the SilcDList.
3568 Currently this list is not used in the SILC just yet, though there
3569 are a lot places where this can replace dynamically allocated
3570 tables and I will fix these places, later, to use SilcDList.
3571 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3572 and use TRQ internally).
3574 Also fixed some annoying warning messages that the original TRQ
3575 code generated. Also minor changes to TRQ's Makefile.in.
3577 * Added support for querying by Client ID to both WHOIS and
3578 IDENTIFY commands into server, as required by the protocol.
3580 * Removed method function pointers from SilcBuffer structure. They
3581 weren't used to anything and just increased the context size for
3582 no good reason. This change also made silc_buffer_alloc and
3583 silc_buffer_free functions inline functions.
3585 * Disabled command flooding detection support until it's fixed so
3586 that it accepts commands in but does not execute them more than once
3589 * Added silc_net_localhost(), to return local hostname, into
3590 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3591 that must be initialized before calling silc_client_init.
3593 * Added new function: silc_server_send_notify_on_channels to send
3594 notify messages to all channels client has joined. It is assured
3595 that the message is sent only once per client.
3597 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3598 lib/silcutil/silcutil.[ch] as silc_format function. The new
3599 function is generic and is used by server as well, not only by
3600 the logging routines.
3602 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3603 the provided version string was not acceptable. Added new function:
3604 silc_ske_check_version into lib/silcske/silcske.h. The function
3605 must be implemented by the application (client or server) and it
3606 does not reside in the SKE library. The function checks the version
3607 string remote end sent.
3609 * Added back pointers (to opaque context and to SilcSocketConnection)
3610 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3612 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3613 duplicate packet context structure.
3615 * Changed `notify' client operation to send same arguments as client
3616 receives from server except for ID's. ID's are mapped to correct
3617 ID entry and that is returned. Also, if channel entry is not sent
3618 by server but the notify is for channel the channel entry is sent
3619 to application (otherwise application doesn't know that it is for
3620 channel (library gets it from packet's Destination ID)).
3622 * Added silc_client_remove_from_channels into client library to
3623 remove a client from all channels it has joined to. Used when
3624 received SIGNOFF notify from server. Added also new function
3625 silc_client_replace_from_channels to replace old ID entry with
3626 new ID entry on all channels. Used when received NICK_CHANGE
3629 * Fixed ID Cache list handling in silc_idlist_get_client in
3630 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3631 to get (or query) client by ID.
3633 * Updated TODO list.
3635 * Added connection authentication status message defined by the
3636 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3637 support for these into the code in client and server side.
3639 * Added generic function silc_client_send_command to send any command
3640 with variable argument list. Application should use this function
3641 to send commands if the command functions provided by the library
3642 does not suite for the application's user interface needs.
3644 * Added new `failure' client operation. Application is notified about
3645 received failure packet if client is executing a protocol. In this
3646 case the protocol's execution has failed.
3648 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3649 is required by the protocol.
3651 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3652 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3655 * Added status flag to SilcSKE object to indicate realtime status
3656 of the SKE protocol.
3658 * Application receives now exactly same command reply arguments as
3659 the library receives from server. However, if ID is received the
3660 corresponding ID entry is returned to the application (eg. Client
3661 ID is mapped to correct SilcClientEntry entry and that is returned).
3662 Changed command_reply client operation due to this change.
3664 * Changed all ID's in commands and in command replys as ID Payloads.
3665 Change affected both client and server side codes.
3667 All ID's sent in SILC network (with execption of ID's in SILC
3668 Packet header) are sent in ID Payload to support variable length
3671 * Server now notifies nick changes and notifies all clients on
3672 the channels about the new nickname (about the new Client ID,
3675 * Implemented CMODE command to change channel modes. Supports all
3676 channel modes defined by the protocol specs except ban and invite
3677 lists. (Also, private channel key mode is supported but support for
3678 setting private channel key in client is missing, thus, this mode
3679 has no effect on client side (except that server requires that the
3680 client uses private channel key and normal channel traffic does not
3683 Also, invite mode works per se, but INVITE command does not work
3684 yet correctly, so you can set channel as invite only channel but
3685 inviting clients to the channel does not work (it is yet to be
3686 thought what's the best way to do it).
3688 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3689 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3690 Implemented CUMODE command to change user's mode on the channel.
3691 Supports all modes defined by the protocol specs.
3693 * Added NAMES command reply to return users modes on the channel.
3695 * Removed unnecessary and slow ciphers from lib/silccrypt.
3697 * Set SO_KEEPALIVE option to connection sockets by default.
3699 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3701 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3702 redefined the Notify Payload into protocol specs.
3704 * Added silc_id_payload_parse_id to get ID directly from raw
3707 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3710 accept searching by Client ID as well.
3712 * Added support for LEAVE and SIGNOFF notify types in client library.
3714 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3715 to parse ID Payload from raw data.
3717 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Added flags parameter into silc_ske_assemble_security_properties
3720 function in lib/silcske/silcske.[ch].
3722 * Changed notify client operation to fit better for notify messages
3723 sent by server. The notify payload received from server is now
3724 passed to the application (after parsing it to SilcNotifyPayload).
3725 It is application's responsibility to retrieve the arguments
3726 from the payload and show the message the way it wants. The message
3727 sent by server is implementation specific.
3729 * Changed public keys to comply with the protocol specification.
3730 Old public keys are not supported anymore and are not compatible.
3732 * Removed nickname from Channel Payload as the latest draft removed
3733 it. The client must resolve the nickname from the NAMES command
3734 reply received when it joined the channel.
3736 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3738 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Fixed some errors in protocol specification drafts.
3742 * Created lib/silccore/silcnotify.c to implement Notify Payload
3743 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3744 generic payloads described by protocol specifications. The file
3745 includes implementations for ID Payload and Argument Payload.
3747 * Changed Command Payload implementation to use the new Argument
3748 Payload. Changed command_xxxx_payload to command_payload_xxxx
3749 to comply with SILC coding conventions.
3751 * Added suppport for Argument Payload handling in Notify Payload
3752 implementation as protocol requires it. Added the new support
3753 into server and client lib as well.
3755 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Added support for multiple nicknames on same channel. [n] is
3758 added locally to the nickname if there are more than one same
3759 nicknames on the channel.
3761 * Server now sends all nicknames that matched WHOIS request.
3762 Client also shows the list received from server.
3764 * Added TOPIC command to client side. User can now set and show
3765 current topic on channel.
3767 * Added MOTD command to client and server. Also, server sends the
3768 motd when client connects to the server.
3770 * Changed version strings to comply ISO 8601.
3772 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Fixed protocol error handling in client library. It should now
3775 cope even if the SKE fails for some reason.
3777 * Made new protocol specification drafts for submitting to IETF.
3779 * Implemented TOPIC command to server in silcd/command.c.
3781 * Added two new notify types into lib/silccore/silcnotify.h:
3782 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3783 notify nickname change and topic setting/change on a channel.
3785 * API change of command_reply operation in client library. The
3786 application gets now the status type received from server as well.
3788 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3792 * Cras fixed and optimized the packet handling even further and
3793 it should work now. Minor change to the prototype of function
3794 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3796 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Added new function into lib/silcutil/silcschedule.[ch]:
3799 silc_schedule_with_fd to select() a specified fd. The function
3800 returns after timeout expires or data arrives or goes. The
3801 function is used by packet routines to wait that all data is
3802 received from network.
3804 * Fixed data reading from network in lib/silccore/silcpacket.c.
3805 The code now assures that all data is read from the fd and then
3806 continues packet processing. This was a bug fix since the code
3807 used to drop some data in some circumstances.
3809 * Added new function into lib/silcclient/client.[ch]:
3810 silc_client_start_key_exchange to start key exchange after
3811 connection has been established to server. The code internally
3812 now uses this funtion but its main purpose was to provide it
3813 for applications that perform their own connecting. After
3814 application has created a connection it merely calls this
3815 function to start the key exchange between client and server.
3816 The library takes care of everything else after that.
3818 Updated also lib/silcclient/README to explain the usage of
3821 * Do not send to application information that connection has
3822 been established. Application gets notified it by connect
3825 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Applied cras's patch to add silc_schedule_one function. The
3828 function runs scheduler once and returns.
3830 * Fixed the scheduler after cras messed it up. The timeout
3831 handling works now as it's supposed to work.
3833 * Added into lib/silccore/ silcnotify.h to include notify
3834 message types support. Changed silc_server_send_notify*
3835 functions, in server.[ch], to support those new notify types.
3836 Added the support for the notify types into client library,
3837 as well. Added new notify client operation into ops.h in
3840 * Changed silc_server_packet_send_to_channel to send normal
3841 packets instead of just channel message packets. The function
3842 is now used to send the notify packets to channels. It is not
3843 used to send channel message packets anymore, as server never
3846 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3847 va_arg()s as it seems to require it nowadays. I guess, if SILC
3848 is compiled with older va_arg() the new code should work anyway.
3850 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Splitted core library. Core library (lib/silccore) includes
3853 now only SILC protocol specific core (and common) components.
3854 Created new utility library (lib/silcutil) that includes more
3855 generic purpose stuff. The stuff for util library was taken
3856 from the old core library. This was minor and easy split.
3858 * Created SILC Client Library (lib/silcclient) that includes
3859 implementation of the SILC client without user interface. This
3860 was major move from silc/ directory. The code has been changed
3861 so that it is transparent towards the user interface. The
3862 silc/ directory includes now the same user interface as before
3863 and it uses the new client library. Read lib/silcclient/README.
3864 Basicly, the client library performs everything else related
3865 to SILC except user interface handling. Also, configuration
3866 files are considered to be part of user interface and library
3867 does not handle them.
3869 This change also changed a lot of structures, function naming etc.
3870 Most important change was that SilcClientWindow object was
3871 renamed to SilcClientConnection in the client library. Created
3872 also new file lib/silcclient/ops.h. Also added new files
3873 silc/local_command.[ch] and silc/client_ops.[ch].
3875 All these changes were made to make it easier for user interface
3876 designers to create what ever user interface for the SILC client
3879 It is also expected that the server will be moved to lib
3880 directory as well and SILC Server Library will be created;
3881 sometimes in the future.
3883 * Removed Local commands from lib/silccore/silccommand.h as
3884 they are application specific and new client library does not
3885 handle any of those anymore.
3887 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3888 old client implementation in silc/.
3890 * Added support for callback functions in SILC_LOG_* macros.
3891 Application can now set its own callbacks that will be called
3892 instead of using the default functions that will always print
3893 the debug messages to stderr (or stdout). Also, debugging can
3894 now be disabled by setting silc_debug to FALSE and re-enabled by
3895 setting it to TRUE. Note, that logging will still work even
3896 if debugging is disabled.
3898 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3899 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3900 silc_log_reset_debug_callbacks.
3902 * To enable debugging in silc client one must give now -d
3903 option on command line.
3905 * Changed silc_schedule_init to automatically allocate task queues
3906 if they are not allocated before calling it.
3908 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Added GMP 3.1 into math library.
3912 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3915 a channel in SILC network. The packet is used by servers and
3916 routers to notify other routers that user has left a channel.
3917 This little feature was missing until now. Added the feature
3918 to protocol specification as well.
3920 Added functions: silc_server_send_remove_channel_user and
3921 silc_server_remove_channel_user into server.[ch].
3923 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3924 lib/silccore/silcpacket.h. However, they are not implemented
3927 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Fixed joining to a channel and sending channel messages
3930 between server and router. The channel message sending should
3931 now work inside a cell.
3933 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Fixed the private message sending between server and router.
3936 The private message sending should now work inside a cell.
3938 * Added silc_server_replace_id into server.[ch] to replace
3939 existing ID in the SILC network.
3941 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3942 and silc_idlist_replace_server_id into idlist.[ch] in server.
3944 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * Fixed the server to server connections. Server can again now
3947 connect to router. Router to router connections probably does
3950 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Added dynamic protocol registering support. Now protocols can
3953 registered and unregistered on the fly. Patch by cras.
3955 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Added lib/contrib directory to hold routines that some platforms
3958 don't have but are needed by SILC.
3960 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3961 into lin/contrib to provide getopt() and getopt_long() for
3962 those who don't have it.
3964 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Added AWAY command to client. When away message is set and
3967 client receives a private message packet the client automatically
3968 replies to the sender with the away message.
3970 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3971 bug seemed to be the cause of recent problems when compiling
3974 * Added version detection support to SKE protocol specification
3975 and added the new changes to the SKE implementation as well.
3976 There were other minor changes in the SKE protocol as well.
3978 Many changes in lib/silcske/silcske.[ch] and in
3979 lib/silcske/payload.[ch].
3981 * Added ^U functionality, clear input line. Patch from cras.
3983 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Mainly small bugfixes on core library. Fixed some debugging
3986 logging and buffer overflow in silclog.c.
3988 * Updated config.sub and config.guess on the distribution tree.
3990 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Added command lagging support in server. Client may execute
3993 commands now only once in two seconds.
3995 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Optimized packet reception. MAC computation and checking is now
3998 also more optimized. A lot previously duplicated code is now
3999 used as generic by both client and server.
4001 * Fixed key pair generation in clientutil.c
4003 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added into lib/silccore/silcbufutil.[ch] new function;
4006 silc_buffer_realloc.
4008 * Moved generic packet sending/encryption functions to
4009 lib/silccore/silcpacket.[ch] from client and server. Some
4010 rewriting of the functions.
4012 * Moved all generic packet reception/decryption functions to
4013 lib/silccore/silcpacket.[ch] from client and server. The
4014 packet processing is now much cleaner in both client and server.
4015 These were major changes in both client and server.
4017 * Created many common functions in server to do packet sending.
4018 Previously code were duplicated a lot, this has been removed
4021 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Rewrote major parts of the ID cache system. Don't know
4024 whether it is better now or not but at least the API is more
4027 * Major rewrite on ID cache stuff on client because of the ID
4028 cache API changes. Added idlist.c to client.
4030 * Also major rewrite on ID cache stuff on server as well.
4031 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4032 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4033 in hand, instead they are all put into the ID cache system now.
4034 All server_idlist_* routines uses ID cache now instead of
4035 traversing its own lists (those lists does not exist anymore).
4036 SilcIDList though still exists. Also, SilcXXXEntry's are
4039 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Finally made the SKE implementation compliant to the protocol
4042 specification. All mp integers are now binary encoded as
4043 opposed being HEX encoded.
4045 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4048 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4049 functions: silc_[encode/decode]_pem. Also added function
4050 silc_encode_pem_file to PEM encode with newlines ('\n') for
4053 * SILC public keys are now encoded either PEM or binary. Same
4054 option is for private keys as well. By default private keys
4055 are binary encoded and public keys PEM encoded. Silly HEX
4056 encoding were removed.
4058 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4059 function to create fingerprints.
4061 * Fixed a bug in SHA1; does not change the original data anymore.
4063 * Partly implemented INFO command on client and server side.
4064 Fixed CLEAR command. Changes to SERVER command; show current
4065 server(s) when giving command without arguments. Added
4066 VERSION command to client.
4068 * Added check to server that unregistered connections cannot
4069 execute commands (unless it is specificly allowed).
4071 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Fixed screen refresh.
4075 * Fixed channel joining bug from client. On some circumstances
4076 client tried to join to a channel it had already joined.
4078 * Added public key verification process into client's protocol.c.
4079 The client now verifies the public key from user and saves
4080 it into ~./silc/serverkeys/ directory.
4082 Added into: clientutil.[ch]: silc_client_verify_server_key.
4084 * Changed SKE protocol's silc_ske_initiator_finish function
4085 to accept callback function that verifies the received public
4086 key. Removed old silc_ske_verify_public_key function.
4088 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4091 silc_pkcs_private_key[_data]_set.
4093 * Made the password and public authentication more cleaner in
4094 server's protocol.c.
4096 * Removed historic and obsolete protocol `channel_auth' from
4097 both client and server.
4099 * Removed wrong way of sending command status messages from
4100 server to client in server's command.c. The old way violated
4101 protocol specification.
4103 Changes to silccore/silccommand.[ch]: removed
4104 silc_command_encode_status_payload -> not needed anymore,
4105 changed silc_command_encode_payload_va to accept extra
4106 argument on variable argument list. The argument type must
4107 now be provided to the function. Also, added new function:
4108 silc_command_encode_reply_payload_va which is same as
4109 normal command_encode_payload_va except command status type
4110 is provided as extra argument.
4112 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Added ~./silc directory handling. The directory includes the
4115 public and private keys for the client.
4117 Added silc_client_check_silc_dir, silc_client_create_identifier
4118 and silc_client_load_keys.
4120 * Implemented SILC protocol compliant public key. Added public
4121 and private key saving to and loading from files.
4123 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4124 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4125 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4126 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4127 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4129 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4130 silc_pkcs_load_[public/private]_key.
4132 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Added silc_server_get_route (route.[ch]) to get connection
4135 data for the fastest route for given ID.
4137 * Implemented INVITE command on client and server. The command
4138 were re-defined in the SILC Protocol Specification and the
4139 implementation now complies with the specification.
4141 * Implemented PING command on client and server.
4143 * Implemented NAMES command on client and server. The server side
4144 supports currently only normal server not router server yet.
4145 Some changes to NAMES definition in SILC protocol specification.
4147 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Implemented LEAVE command on client and server.
4151 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4152 again. This change was made to the protocol as well. Server
4153 should not violate the protocol specification anymore.
4155 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4158 was tested. SOCKS4 was not but should work anyway.
