3 * Assure that the packet length digged from the actual packet
4 is something sensible in the silc_packet_decrypt_rest_special
5 in lib/silccrypt/silcpacket.c.
7 * Free and NULL the allocated pointer in silc_hmac_alloc if
8 the HMAC allocation fails. The affected file is
9 lib/silccrypt/silchmac.c.
11 * Print the selected security properties to the log files in
12 the server. Affected file silcd/protocol.c.
14 * Add SKE's reference counter even if calling the completion
15 callback manually. Otherwise it goes negative, although it
16 does not cause any problems. The affected file is
17 lib/silcske/silcske.c.
19 * Remove the client entry with short timeout after giving the
20 KILL command. Affected file lib/silcclient/command.c.
22 * Fixed to send error reply in WHOIS and IDENTIFY commands in
23 case all found clients are already disconnected (WHOWAS would
24 found them) in the server. Affected file silcd/command.c.
26 * Update the last_receive (time of last data received) to be
27 updated only when received private or channel message so that
28 the idle time showed in WHOIS makes more sense.
30 * Added boolean field `valid' in to the SilcClientEntry in the
31 client library to indicate whether the entry is valid or not.
32 This fixes the nickname change bug on channel when changing
33 the nickname to be same than the old (like nick to Nick) the
34 nickname formatter doesn't set the new nick anymore to Nick@host.
35 Affected file lib/silcclient/idlist.[ch].
37 * Now actually fixed the nickname changing on disconnection.
38 Added new function silc_change_nick to the Irssi SILC Client.
39 Affected file irssi/src/silc/core/client_ops.c,
40 irssi/src/silc/core/silc-nicklist.[ch].
42 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
44 * Check that the public key exists in the GETKEY command before
45 trying to encode it. Affected file silcd/command.c.
47 * Print some notifications on received public keys with GETKEY
48 command in the Irssi SILC Client. Affected files are
49 irssi/src/fe-common/silc/module-formats.[ch],
50 irssi/src/silc/core/client_ops.c.
52 * Use IDENTIFY command to resolve the server information in the
53 GETKEY command instead of INFO command. Affected file
54 lib/silcclient/command.c.
56 * All command reply functions in the client library now calls
57 the pending command reply callbacks even if an error has
58 occurred. The server has done this a long time and now it was
59 time to move the client library to this as well. Now all
60 errors can be delivered back to the pending command reply
61 callbacks if necessary. Affected files are
62 lib/silcclient/command[_reply].[ch].
64 * Change the nickname on disconnection back to the username
65 because in reconnect the server will enforce it to it anyway.
66 Affected file irssi/src/silc/core/silc-servers.c.
68 * Fixed a config file parsing bug in the Irssi SILC client.
69 Affected file irssi/src/silc/core/clientconfig.c.
71 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
73 * When printing the channel mode on JOIN, verify that the
74 channel key and channel's HMAC are valid. Affected file
75 irssi/src/silc/core/client_ops.c.
77 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
79 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
80 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
81 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
83 * Removed channel key rekey task deleting from the function
84 silc_server_save_channel_key. Affected file silcd/server.c.
85 Added explicit timeout task context instead that is used to
86 delete the task if we are registering a new task before the
89 * When channel key rekey occurs the client library now saves
90 the old channel key for a short period of time (10 seconds) and
91 is able to use it in case some is still sending channel
92 messages encrypted with the old key after the rekey. Affected
93 file lib/silcclient/[idlist.h|client_channel.c].
95 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
97 * Added check to the silc_server_new_id_real to not accept
98 new ID if it is the sender's own ID. Affected file is
99 silcd/packet_receive.c.
101 * Assure that we do not announce ourself or the one we've
102 sending our announcements when we're router and are announcing
103 servers to our primary router. Affected file silcd/server.c.
105 * Fixed silc_server_command_identify_check_client to assemble
106 correct WHOIS packet. It send corrupted WHOIS packet and
107 caused problem with router to router connections. Affected
108 file silcd/command.c.
110 Fixed also silc_server_command_whois_check the same way
111 as for the IDENTIFY command.
113 * Added new SilcIDListStatus to the server in the SilcIDListData
114 structure. The status now includes the current status of
115 the entry (like registered, resolved etc.). Affected file
116 silcd/idlist.[ch]. Defined a bunch of different status types
117 as well. This replaced the old boolean registered field as well.
119 Added resolve_cmd_ident field to the SilcClientEntry structure
120 too so that if the entry is for example being resolved so
121 another command may attach to the same pending command reply
122 without requiring to resolve the same entry again. This concept
123 should optimize the WHOIS and the IDENTIFY resolving under
124 heavy load by taking away unnecessary resolving for entries
125 that are being resolved already.
127 Added support for adding multiple pending commands for one
128 command idenfier. Affected file silcd/command[_reply].[ch].
130 * Fixed WHOIS and IDENTIFY save to remove the cache entry
131 before deleting the data. Otherwise the hash table will have
132 freed data in comparison functions. Affected file is
133 silcd/command_reply.c.
135 * Fixed silc_idlist_replace_client_id to add the new entry to
136 the cache with NULL nickname. Otherwise there will be invalid
137 memory as the nickname after the nickname is freed. Affected
138 file silcd/packet_receive.c.
140 * Fixed the silc_idlist_get_clients_by_hash. The entries was
141 saved into wrong slots because the previous number of entries
142 was not taken into account. Affected file silcd/idlist.c.
143 Fixed same thing in silc_idlist_get_clients_by_nickname too.
145 * If we are router and we receive JOIN notify to a channel that
146 does not have any users then notified client is marked as the
147 channel founder, as it is it. The affected file is
148 silcd/packet_receive.c
150 * Added to the extended hash table API's table_del_*ext functions
151 the destructor as argument too, so that the caller can decide
152 which destructor to use or whether to use destructor at all.
153 Affected file lib/silcutil/silchashtable.[ch].
155 * Fixed ID Cache purging. It actually deleted the entries from
156 the hash table after the data was freed. The hash table ended
157 up comparing freed memory. The affected file is
158 lib/silccore/silcidcache.c.
160 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
162 * Fixed Irssi SILC client's KILL command's HELP syntax.
164 * The USERS command now resolves the detailed user information
165 if the userinfo field is missing. Affected file is
166 lib/silcclient/command_reply.c.
168 * Do not print error in silc_file_read if the read file does
169 not exist. Just silently return NULL. Affected file is
170 lib/silcutil/silcutil.c.
172 * Fixed the silc_log_output to not wine about NULL filename
173 and to not create some bogus " " filename. Affected file is
174 lib/silcutil/silclog.c.
176 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
178 * Fixed various printing bugs on the user interface in the
179 Irssi SILC Client. Minor changes that were forgotten from
182 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Fixed the configure.in.pre and the compilation and distribution
185 environment to support the new autoconf 2.52. That version is
186 now required to compile the CVS trunk.
188 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Renamed function silc_parse_nickname to silc_parse_userfqdn
191 to generally parse user@fqdn format strings. Affected file
192 lib/silcutil/silcutil.c.
194 * Added nickname_format and nickname_force_format fields to the
195 SilcClientParams structure. The first one defines the format
196 for the nicknames that the library will enforce if the receives
197 multiple same nicknames. The second one is boolean value and
198 can be used to force the library to always enforce the format
199 to the nicknames regardles whether there are multiple nicknames
200 or not. This configurable formatting was employed to flexibly
201 support accessing multiple nicknames from the user interface.
202 The userinterface can now set the nicknames to what ever format
203 they prefer. Affected file lib/silcclient/silcapi.h.
205 Added function silc_client_nickname_format to the file
206 lib/silcclient/idlist.c. It performs the nickname formatting.
208 Added new field `hostname´ to the SilcClientEntry context.
209 It holds the hostname of the client. Affected file is
210 lib/silcclient/idlist.h.
212 * Irssi SILC Client sets the nicknames in nick@hostn format.
213 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
214 irssi/src/silc/core/silc-core.c.
216 The WHOIS printing now also shows both the real nickname and
217 the formatted nickname so that user knows how to access the
218 user if there are multiple same nicknames cached. Affected
219 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
220 printing formatting too to take the hostname now as a separate
221 argument. The Affected file is
222 irssi/src/fe-common/silc/modules-formats.[ch].
224 * Changed the silc_client_get_clients_local to accept the formatted
225 nickname as argument. It accepts the real nickname too but the
226 formatted nickname can be used to find the true entry from
227 multiple entries. Affected file lib/silcclient/silcapi.h and
228 lib/silcclient/idlist.c.
230 * Added nickname_format_parse field to the SilcClientParams.
231 It is a callback function provided by the application to parse
232 the nickname out of the formatted nickname string. The library
233 calls it to get the nickname from the formatted string. Since
234 the application generally knows better the format of the nickname
235 string it parses it instead of the library, even though library
236 encodes the formatted string. If the callback function is not
237 provided then the library will use the string as is. The
238 affected file is lib/silcclient/silcapi.h.
240 * All the nickname strings passed to the client library in
241 commands are now expected to be formatted nickname strings.
242 If the command does not support the formatted nickname string
243 it will assume that the sent string is the actual nickname.
244 Affected file lib/silcclient/command.c.
246 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Added public key authentication support to OPER and SILCOPER
249 commands in the client library. Affected file is
250 lib/silcclient/command.c.
252 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Changed the get_auth_methdod client operation to be asynchronous.
255 It can be async if the application resolves the authentication
256 method from the server during the negotiation. Added new
257 SilcGetAuthMeth completion callback that the application will
258 call after resolving the authentication method.
260 Added function silc_client_request_authentication_method that
261 the application can use to resolve the authentication method
262 from the server. Added also SilcConnectionAuthRequest callback
263 that the library will call after the server has replied. The
264 application can call this function if it does not know the
265 current authentication method.
267 Affected files are lib/silcclient/client.c and
268 lib/silcclient/silcapi.h.
270 * The Irssi SILC client now automatically resolves the authentication
271 method incase any configuration information is not present (and
272 currently there never is). The affected file is
273 irssi/src/silc/core/client_ops.c.
275 * Fixed public key authentication from the client library.
276 Affected file lib/silcclient/protocol.c. Changed also the
277 protocol specification about the public key authentication in
278 the connection authentication protocol. The actual data to be
279 signed is now computed with a hash function before signing.
281 * Fixed the public key authentication from the server as well.
282 Affected file silcd/protocol.c.
284 * Removed the mlock()'s from the memory allocation routines.
285 Affected file lib/silcutil/silcmemory.c. The ./configure does
286 not check anymore for the mlock(). Affected file is
289 * Fixed USERS command in server to allow the execution of the
290 command for private and secret channels if the client sending
291 the command is on the channel. Affected file silcd/command.c.
293 * Fixed silc_client_get_clients_local to return the clients
294 count correctly. It could return wrong value. Affected file
295 lib/silcclient/idlist.c.
297 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
299 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
300 types. The assembler optimizations seemed not to like 64-bit
301 data types. The assmebler optimizations thus are now enabled
302 also for BSD systems as opposed to only enable them for Linux.
304 * Do not check for threads at all on BSD systems. Affected
305 file configure.in.pre.
307 * Removed -n and -h options from the Irssi SILC Client since
308 they are not used in silc.
310 * Fixed the prime generation to assure that the first digit
311 of the generated random number is not zero since our conversion
312 routines does not like number strings that starts with zero
313 digit. If zero digit is seen the random number is regenerated.
314 This caused some corrupted RSA keys when the zero first digit
315 was met. Affected file lib/silcmath/silcprimegen.c.
317 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
319 * Fixed WIN32 configuration in the ./configure script.
320 Fixed to include xti.h on environments that has it.
321 Patches by Carsten Ilchmann and andrew.
323 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
325 * Changed the silc_id_create_client_id to be collision
326 resistant. It is now assured that there cannot be created
327 two same client ID's. I suspect that some weird bugs in
328 the server were actually caused by duplicate Client IDs.
329 Affected file silcd/serverid.[ch]. A router receiving
330 new ID now also assures and informs the sending server
331 if the ID caused collision.
333 * Changed the silc_id_create_channel_id to also assure that
334 there are no collisions.
336 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
338 * Statement about ignoring the Mutual Authentication flag when
339 performing rekey with PFS was a bit misleading. It is ignored
340 if it was set in the initial negotiation, it cannot be even
341 set in the rekey. Fixed in the ke-auth draft. Started the
342 new versions of the protocol drafts in the doc/.
344 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
346 * Fixed a bug in silc_client_command_identify_save when saving
347 new channel information. The channel name was no duplicated
348 and caused crash on exit. Affected file is
349 lib/silcclient/command_reply.c.
351 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
353 * Fixed the getkey command handling in the server. Send just
354 empty OK reply to the sender if the key could not be fetched
355 (but everything else was ok, like the key just was not available).
356 Changed the public key parameter to optional in the protocol
357 specs so that empty OK reply can be sent. Affected file
360 Added a message to Irssi SILC client to tell to user if the
361 server did not return a public key.
363 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
365 * Fixed a channel key regeneration bug. It registered new
366 timeout tasks exponentially until all system resources were
367 used. Affected file silcd/server.c.
369 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
371 * Added the SILC Document generator to the scripts/silcdoc.
372 It can be used to generate the Toolkit Reference Manual out
373 of the source tree. Internally it will also use the RoboDoc
374 generator now imported in util/robodoc.
376 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
378 * Added couple of return's in rekey protocol if error orccurred
379 during the protocol. The execution must be terminated.
380 Affected file silcd/protocol.c. Also, terminate the protocol
383 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
385 * The client's Client ID was created initally from the wrong
386 nickname (it could have been in format nick@host) in the
387 silc_server_new_client. Affected file silcd/packet_receive.c
389 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
391 * Added some SILC_LOG_ERROR's to various error conditions
392 if client could not be added to ID cache. Affected files
393 silcd/packet_receive.c and silcd/server.c.
395 * When client's sock->user_data is freed, NULL also the
396 client->router and client->connection pointers. Added check
397 for these pointers being NULL to various places around the
398 code. Affected file silcd/server.c.
400 * Added client->data.registered == TRUE checks to various
401 places around the code to assure that unregistered client's
402 are not handled when it is not allowed. Affected file
405 * Added `bool registered' fields to all
406 silc_idlist_[server|client]_get_* routines to indicate whether
407 the fetched client needs to be registered or not. Affected
408 file silcd/idlist.[ch].
410 * Add your own entry as registered to the ID cache in the
411 server. Affected file server.c.
413 * Fixed a bug in silc_server_new_server. The SilcServer was
414 set as the new server's context instead of SilcServerEntry.
415 This naturally caused some weird bugs.
417 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
419 * Do not delete the channel rekey task when adding it
420 for in silc_server_create_channel_key.
422 * Changed the silc_server_create_channel_key to return
423 TRUE or FALSE to indicate the success of the channel key
426 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Fixed MSVC++ project files and added missing files to
429 Makefiles under win32/.
431 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
433 * Do not add TCP_NODELAY flag if the operating system
434 does not have it defined. Affected files are
435 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
437 * Fixed buffer overflow from Irssi SILC Client. Affected
438 file irssi/src/fe-common/core/themes.c.
440 * Fixed double free in client library in the file
441 lib/silcclient/client.c when disconnecting from server.
443 * Applied double free patch from cras to Irssi SILC client.
444 Affected files irssi/src/core/[modules/expandos].c
446 * Fixed the disconnection handling to Irssi SILC Client.
447 The application must call silc_client_close_connection
448 in ops->connect client operation in case of failure of
449 the connection. Affected file is
450 irssi/src/silc/core/client_ops.c.
452 * Do not set sock->protocol to NULL in the function
453 silc_client_close_connection after executing the protocol's
454 final callback since the sock might not be valid anymore.
455 Affected file lib/silcclient/client.c.
457 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
459 * Do not enable SILC_THREADS if the linking with libpthread
460 did not happen. Affected file configure.in.pre.
462 * Added notion to protocol specification that server must
463 verify the sent authentication payload with CMODE when
464 setting the channel founder key. Implemented it to the
465 server. Affected file silcd/command.c.
467 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
469 * Added _EXTRA_DIST SILC distribution variable to the
470 distributions file. It is used to conditionally add extra
471 files or directories to the specific distribution. Affected
472 files ./prepare, Makefile.am.pre and distributions.
474 Removed the `_' from the start of the distribution names.
477 * Added README.WIN32 for instructions to compile the Toolkit
480 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Fixed a double free in disconnection in the server. Affected
483 file is silcd/server.c.
485 * Fixed the lib/silcske/groups.c to work now also with GMP
486 MP library. The string conversion did not work when using
487 specific base and the base is indicated in the string as well.
489 * Created win32/ directory which now includes MSVC++ specific
490 stuff so that toolkit (DLLs) may be compiled with MSVC++.
491 It will appear only in the toolkit distribution
493 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Changed the key material distribution function in case when
496 the hash output is too short. The data is now concatenated
497 a bit differently than it used to. Made the change to the
498 SKE protocol specification.
500 * Added better GMP detection to configure.in.pre. A patch
503 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Fixed a minor bug in SKE that might cause some problem on
506 some platforms. Affected file lib/silcske/silcske.c.
508 * Added the cookie checking for initiator in the SKE. It checks
509 that the responder returns the sent cookie unmodified. The
510 affected file is lib/silcske/silcske.c. Added new SKE
511 error type INVALID_COOKIE that can be sent during the
512 negotiation. Fixed some memory leaks as well.
514 * Added the "invalid cookie" error message to Irssi SILC client's
517 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
519 * Added `task_max' field to the SilcClientParams to indicate
520 the maximum tasks the scheduler can handle. If set to zero,
521 default values are used. Affected file lib/silcclient/silcapi.h.
523 * Fixed memory leaks in silc_client_close_connection. Affected
524 file lib/silcclient/client.c.
526 * Added silc_client_del_client_entry to client library to free
527 all memory of given client entry. Affected file is
528 lib/silcclient/idlist.[ch].
530 * Added new functions silc_client_del_channel and
531 silc_client_del_server to delete channel and server entries.
532 Affected file lib/silcclient/[silcapi.h/idlist.c].
534 * Removed silc_client_del_client_by_id from silcapi.h.
536 * Fixed the INFO command to return the server's own info
537 correctly when querying by Server ID. Affected file is
540 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
542 * Removed the non-blocking settings in WIN32 code in the
543 silc_sock_[read/write] and added SleepEx instead. Affected
544 file lib/silcutil/win32/silcwin32sockconn.c. The availability
545 of input data is now checked with FIONREAD and ioctlsocket.
547 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Call silc_schedule_task_del_by_context in the
550 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
551 Affected file lib/silccore/silcprotocol.c.
553 * Call silc_protocol_cancel for active protocols in the
554 silc_server_close_connection if the funtion
555 silc_server_free_sock_user_data has not been called.
556 Affected file silcd/server.c.
558 * Generic tasks cannot be deleted using the del_by_fd
559 task deleting function since generic tasks does not match
560 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
562 * Added a notion to SILCOPER help file that the SILCOPER works
563 only on router server, not on normal server.
565 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
567 * Added for WIN32 support for the new scheduler as well.
568 Affected file lib/silcutil/win32/silcwin32schedule.c.
570 * Fixed the SHA1 implementation to work on various platforms.
572 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
574 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
575 API. It is part of the scheduler now. Everything else is
576 as previously but some functions has changed their names.
577 Checkout the lib/silcutil/silcschedule.h for the interface.
578 Updated all applications to use the new interface. Affected
579 files are lib/silcutil/silcschedule.[ch].
581 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
583 * Found a bug in the SKE implementation. The HASH value,
584 specified by the protocol, was not computed correctly. The
585 public key of the responder was not added to the computation
586 even though it is mandatory. Affected file lib/silcske/silcske.c.
587 This unfortunately causes incompatibilities with older
590 * Added WIN32 specific network init and uninit functions:
591 silc_net_win32_init and silc_net_win32_uninit to init and uninit
592 the Winsock2. Affected file lib/silcutil/silcnet.h and
593 lib/silcutil/win32/silcwin32net.c.
595 * Set the socket always to nonblocking mode on WIN32 after
596 reading data or writing data. Affected file is
597 lib/silcutil/win32/silcwin32sockconn.c.
599 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
601 * Fixed various compilation problems under WIN32. Affected
602 files lib/silcutil/win32/silcwin32thread.c and
603 lib/silcutil/win32/silcwin32schedule.c.
605 * Removed all _internal.h #includes from public header
606 files. Internal headers must never be included from
609 Removed also the lib/silcske/payload_internal.h file.
611 * All include files that may be needed (public and some others
612 included by the public headers) by application developers are
613 now copied to the ./includes directory. It does not copy any
614 internal headers. Affected file Makefile.defines.pre and all
615 Makefile.am's under lib/ and subdirs.
617 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Do not change the ~/.silc directory's permissions automatically.
620 Affected file irssi/src/silc/core/clientutil.c.
622 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
624 * Do not cancel the protocol in silc_server_close_connection
625 it might cause recursion. Now cancelled in the function
626 silc_server_free_sock_user_data. Affected file silcd/server.c.
628 * Fixed the silc_server_remove_clients_by_server to regenerate
629 the channel keys correctly finally. Added also new function
630 silc_server_remove_clients_channels to actually do it.
631 Affected file silcd/server.c.
633 * Fixed the silc_server_new_channel to not crash by giving
634 wrong router to the new channel. Affected file is
635 silcd/packet_receive.c.
637 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
639 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
640 which is given as argument to the silc_client_alloc now.
641 It can be used to configure the client and set various parameters
642 that affect the function of the client.
644 * The USERS command in server did not check whether the channel
645 is private or secret. Affected file silcd/command.c.
647 * Added new argument to the USERS command in protocol specification.
648 The USERS command now can take the channel name as argument
649 as well. Added support for this in client and server and
650 updated the protocol specs.
652 * Completed the GETKEY command in client. It can be now used
653 to fetch also servers public key not only some clients.
654 Affected files lib/silcclient/command[_reply].c.
656 * Added silc_client_get_server to return server entry by the
657 server name. Affected files lib/silcclient/silcapi.h and
660 * Redefined the IDENTIFY command in protocol specification to be
661 more generic. It now can be used to query information about
662 any entity in the SILC Network, including clients, servers and
663 channels. The query may be based either the entity's name
664 or the ID. Added support for this in both client and server.
666 Affected files silcd/command.c and lib/silcclient/command.c
669 * Optimized the WHOIS and WHOWAS commands in the server. Removed
670 the _from_client and _from_server functions. Affected file
673 * Added silc_client_get_channel_by_id_resolve to the file
674 lib/silcclient/silcapi.h to resolve channel information by
675 its ID. Added also silc_client_get_channel_by_id that
676 does not resolve it from the server.
678 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Added SilcServerEntry context into the client library
681 to represent one server. The INFO command now allocates
682 these to save the resolved server info. For now on the
683 client library will also keep information about servers,
684 connected and resolved with INFO.
686 The INFO command now allocates the SilcServerEntry context
687 and saves the server info there. The COMMAND_REPLY in
688 the INFO now returns the parameters to application in
689 same order as defined in the protocol specification.
691 The entries are cached in the client->server_cache.
693 * The INFO command is now issued after received the Client ID
694 from the server. Affected file lib/silcclient/client.c.
696 * The CMODE_CHANGE notify may now return also an SilcServerEntry
697 to the application as the mode changer might be server.
698 It is guaranteed that NULL is not returned anymore to the
699 application. Affected file lib/silcclient/client_notify.c.
701 The ID Type is now also passed to the application so that
702 it can check whether the returned entry is SilcClientEntry
705 Added new function silc_client_get_server_by_id to return
706 the server entry by ID. Affected files are the
707 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
709 * Do not create the channel in the Irssi SILC Client when issuing
710 the JOIN command but when received the sucessful JOIN command
711 reply. Otherwise the channel might get created even though we
712 could not join it. The Affected file is
713 irssi/src/silc/core/[silc-channels.c/client_ops.c].
715 * Fixed a channel joining bug in router. The router must also
716 check the channel modes, invite and ban lists etc. when serving
717 the JOIN command sent by normal server. Affected file is
718 silcd/command.c. The router now resolves the client's
719 information from the server who sent the JOIN command if it
720 does not know it, and processes the JOIN command only after
723 * Changed the SilcCommandCb to take new argument; void *context2.
724 Affected file lib/silccore/silccommand.h
726 The second argument in the command callbacks in the server now
727 includes the SilcServerCommandReplyContext if the command was
728 called as pending command callback from the command reply.
729 Otherwise it is NULL. When called as pending the status of the
730 command reply will be checked and if it was erronous the
731 error will be sent to the original sender of the command.
732 This way the client always receives the error messages even
733 though the server was actually the one who received the error
734 when it resent the command to router, for example. Affected
735 files silcd/command[_reply].[ch].
737 * Fixed sending WHOWAS command's error message to client if
738 the requested client could not be found. It was missing.
741 * Changed the CMODE and CUMODE commands reply arguments in the
742 protocol specification. The Channel ID is now sent in both
743 of the commands to identify the channel. Implemented this
744 new feature to the client and server. Affected files
745 lib/silcclient/command_reply.c and silcd/command.c.
747 * Made better checks for invite and ban lists in the JOIN
748 command in server. Affected file silcd/command.c.
750 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
752 * The server now performs the incoming host IP/DNS lookup
753 using the silc_socket_host_lookup and thus does not block
754 the server anymore. Affected file silcd/server.c.
756 * Completed the multi-thread support for SILC Scheduler in
757 the lib/silcutil/silcschedule.c.
759 * Fixed the configure.in.pre to detect the pthread correctly
762 * Fixed a deadlock in silc_task_queue_wakeup in the file
763 lib/silcutil/silctask.c.
765 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
767 * Added new function silc_schedule_wakeup that is used in
768 multi-threaded environment to wakeup the main thread's
769 schduler. It needs to be used when a thread adds a new task
770 or removes a task from task queues. After waking up, the
771 scheduler will detect the task queue changes. If threads
772 support is not compiled in this function has no effect.
773 Implemented the wakeup mechanism to both Unix and WIN32
774 systems. Affected files are lib/silcutil/silcschedule.[ch],
775 lib/silcutil/unix/silcunixschedule.c and the
776 lib/silcutil/win32/silcwin32schedule.c.
778 * Added new function silc_task_queue_wakeup to wakeup the
779 scheduler by the specified task queue. Affected file
780 lib/silcutil/silctask.[ch].
782 * The silc_socket_host_lookup_start now wakes up the scheduler
783 after adding the timeout task. Affected file is
784 lib/silcutil/silcsockconn.c.
786 * The silc_socket_host_lookup is synchronous now if the threads
787 support is not compiled in. However, the callback is still
788 called asyncronously through the scheduler, anyway. Affected
789 file lib/silcutil/silcsockconn.c.
791 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
793 * Added new function silc_socket_host_lookup to perform
794 asynchronous IP and FQDN lookups for the socket connection.
795 Affected files lib/silcutil/silcsockconn.[ch].
797 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
799 * Added SILC_MUTEX_DEFINE to define the mutex on environments
800 that may or may not compile the mutex support in.
802 Changed the silc_mutex_alloc interface. It allocates the
803 mutex now to the sent pointer and returns TRUE or FALSE.
805 Affected file lib/silcutil/silcmutex.h.
807 * Wrote the SILC Task Queue interface to support multi-threads.
808 Affected file lib/silcutil/silctask.[ch].
810 * Wrote the SILC Scheduler to support multi-threads. Affected
811 file lib/silcutil/silcschedule.c.
813 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Implemented the SILC Mutex API and SILC Thread API for WIN32
816 in lib/silcutil/win32/.
818 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
820 * Defined SILC Mutex API and SILC Thread API and implemented
821 them for Unix. Affected files are
822 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
823 lib/silcutil/unix/silcunixmutex.c and
824 lib/silcutil/unix/silcunixthread.c.
826 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Fixed the silc_server_remove_clients_by_server's channel
829 key re-generation. The hash table handling was incorrect
830 and would not work with many channels. Affected file is
833 * Fixed some memory leaks around the server code.
835 * Rewrote the silc_server_get_users_on_channel to support IPv6
836 based Client ID's. Affected file silcd/server.c.
838 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
839 specification. However, a separate document must be written
840 to define the detailed signing procedure and the payload
841 associated with the flag. Defined the flag to the
842 lib/silccore/silcchannel.h as well.
844 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Changed the dynamic tables to static size tables in the
847 lib/silccrypt/silchmac.c.
849 * Removed GCC dependencies from the code. A patch by cras.
851 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Do not show the error "Error receiving packet bla bla"
854 in server if it really was not an error (-2 means that reading
855 is pending). Affected file silcd/server.c.
857 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Fixed a possible crash in silc_server_remove_clients_by_server
860 in silcd/server.c. Fixed there also some memory leaks.
862 * Fixed the silc_idlist_replace_client_id. It could replace
863 wrong key in the hash table. Affected file silcd/idlist.c.
865 * Do not check whether there are global users on the channel
866 if the channel->global_users is FALSE. Affected functions
867 silc_server_remove_from_one_channel and
868 silc_server_remove_from_channels in silcd/server.c. Also,
869 do not check if the removed client is local as we can be
870 sure that global client was not removed from the channel
871 and checking for global users is not needed.
873 * The silc_server_remove_clients_by_server now re-generates
874 the channel keys correctly for those channels that had
875 clients removed from them. Affected file silcd/server.c.
877 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
879 * Found the reason of random crashes in the server. We weren't
880 ignoring the SIGPIPE signal (which can be sent in write())
881 and it crashed the server. Affected file silcd/silcd.c.
883 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Assure that sock->user_data is not NULL in the function
886 silc_server_packet_send in silcd/packet_send.c.
888 * Disconnect the remote connection if it could not be added
889 to any ID lists in the server. The affected file is
892 * Check in silc_server_packet_send[_real/dest] that the
893 socket is not disconnecting and ignore the data if it is.
894 Affected file silcd/packet_send.c.
896 * Define inline to __inline on native WIN32 compilation.
897 Affected file includes/silcwin32.h.
899 * Added some explicit type casts for inline code since MSVC
900 require them. Affected files lib/silcutil/silcbuffer.h,
901 lib/trq/silcdlist.h and lib/trq/silclist.h.
903 * Print warning in log files from now on if the packet
904 decryption fails. Affected file silcd/server.c.
906 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
908 * Changed the `say' client operation's interface to accept
909 new `type' argument to indicate the type of the message sent
910 by the library. The application may filter the library's
911 messages according the type. The affected file is the
912 lib/silcclient/silcapi.h.
914 * Added two new functions to lib/silcclient/silcapi.h:
915 silc_client_del_client and silc_client_del_client_by_id.
916 Affected file lib/silcclient/idlist.c.
918 * Moved the clientincludes.h from includes/ to silc/ and
919 serverincludes.h from includes/ to silcd/.
921 * The modes for the CMODE and CUMODE are now passed as
922 uint32 for application with COMMAND_REPLY. The affected
923 file is lib/silcclient/command_reply.c.
925 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
927 * /WHOIS without arguments shows client's own information.
928 Affected file lib/silcclient/command.c.
930 * Changed PING to not accept any arguments. The specs
931 says that client can ping only the connected server so
932 requiring an argument is not needed. Affected file is
933 lib/silcclient/command.c.
935 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Fixed a fatal bug in private message sending and reception
938 encryption and decryption when using private message keys.
939 The implementation was incorrect and did not follow the
940 specification. It causd that some of the message were
941 lost since it did not use the sending and receiving keys
942 as the protocol suggests. This has been fixed and will cause
943 incompatibilities with older clients when sending private
944 message encrypted with private message keys. Affected files
945 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
946 and various other in Irssi SILC Client.
948 Added `responder' boolean argument to the functions
949 silc_client_add_private_message_key[_ske] to indicate when
950 the key is added as responder or initiator of the key
953 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Removed the silc_ske_check_version function and created
956 a SilcSKECheckVersion callback. Added also a function
957 silc_ske_set_callbacks that is now used to set all SKE
958 callbacks. The callback functions are not given to
959 the SKE functions anymore, but this function is used to
962 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
964 * Added `silc_version' argument to the silc_client_alloc
965 to define the version of the application for the library.
966 The library will use the version string to compare it
967 against the remote host's (usually a server) version
968 string. Affected file lib/silcclient/silcapi.h
970 * Added the KE protocol context to Key Agreement context
971 in client library so that we can abort the SKE if it
972 is in process when we get timeout. Affected file is
973 lib/silcclient/client_keyagr.c.
975 * Do not resolve the client ID forever if it returns in the
976 first time that such client does not exist. This was done
977 for example with private message. Affected file is
978 lib/silcclient/client_prvmsg.c.
980 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Do not add regex.h for WIN32. The affected file
983 includes/silcincludes.h.
985 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
986 not work yet 100%. It generates the DLL's automatically
987 when compiling with --with-win32 under cygwin.
989 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
991 * lib/contrib/regex.c is not compiled on WIN32.
993 * Added silc_net_get_socket_opt function to the
994 lib/silcutil/silcnet.h.
996 * Added includes/silcwin32.h for WIN32 specific includes
999 * Do not use ptime structure or any of the posix process
1000 functions on WIN32 in lib/silccrypt/silrng.c.
1002 * Added silc_gettimeofday to provide generic function
1003 for struct timeval on all platforms. Added the function
1004 to lib/silcutil/silcutil.h.
1006 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1009 library as they clearly belong there. As a plus side we
1010 can make the actual socket connection routines platform
1013 Added also new generic function silc_socket_read and
1014 silc_socket_write (that used to be silc_packet_[read/write].
1015 The implementation of these are platform specific.
1017 * Added WIN32 specific routines of silc_socket_[read/write]
1018 to lib/silcutil/win32/silcwin32sockconn.c.
1020 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Added preliminary support for native WIN32 compilation under
1023 cygwin (using the -mno-cygwin option for GCC) to the
1024 ./configure.in.pre. The --with-win32 now prepares the
1025 compilation for native WIN32.
1027 * Rewrote the SILC Scheduler interface in the file
1028 lib/silcutil/silcschedule.h. The scheduler is now context
1029 based and does not have anymore any global static scheduler.
1030 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1031 and created lib/silcutil/win32 directory for WIN32 based
1034 * Added Unix specific network routines to the
1035 lib/silcutil/unix/silcunixnet.c and the old
1036 lib/silcutil/silcnet.c includes now only generic routines.
1038 Added WIN32 specific network routines to the
1039 lib/silcutil/win32/silcwin32net.c.
1041 * Added Unix specific utility functions from the
1042 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1044 * Added WIN32 SILC Scheduler to the file
1045 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1048 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Do not handle JOIN notify in the server if the target client
1051 is not registered (idata->registered == FALSE). The affected
1052 file is silcd/packet_receive.c.
1054 * Update the nickrec->founder in event_cumode in the Irssi SILC
1055 client. Affected file irssi/src/silc/core/silc-channels.c.
1057 * Fixed the CUMODE_CHANGE notify handling in the server when
1058 server and router are announcing their clients on channels.
1059 Now the mode changes are saved and notified correctly. The
1060 affected file is /silcd/packet_receive.c.
1062 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1063 They really did not replace the cache entry in the ID Cache.
1064 Now they do that. Affected file silcd/idlist.c.
1066 * Fixed the KICK notify handling in the Irssi SILC client to
1067 update the channel records so that the kicked client does not
1068 appear to be on the channel. The affected file is
1069 irssi/src/silc/core/silc-channels.c.
1071 * Always update the conn->current_channel when executing command
1072 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1074 * Fixed the KILL notify handling in Irssi SILC client to remove
1075 the killed client on all channels.
1077 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Fixed the silc_parse_command_line to remove extra spaces
1080 from the start and end of the arguments. Affected file is
1081 lib/silcutil/silcutil.c.
1083 * Cancel and free any active protocol in the function
1084 silc_server_close_connection. Affected file silcd/server.c.
1086 * Cancel and free any active protocol in the function
1087 silc_client_close_connction. Affected file is
1088 lib/silcclient/client.c.
1090 * Do not execute the KILL command for clients that are in
1091 history (ie. they are not in the network). Affected file is
1094 * Fixed KILL notify handling, client does not crash anymore.
1095 Affected file irssi/src/silc/core/silc-channels.c.
1097 * Reduced the default packet buffer size from 2048 to 1024 in
1098 lib/silccore/silcpacket.c.
1100 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1101 counter to the SKE context that is incresed when the SKE library
1102 performs async operation outside the library. If the outside
1103 process frees the SKE context and FREED status will be set
1104 and the library will detect after the sync operation that the
1105 libary is freed. The affected files are
1106 lib/silcske/silcske[_status].[ch].
1108 * Resolve the client entry information in the function
1109 silc_client_channel_message to assure that NULL pointer is not
1110 passed as client entry to the application. */
1112 * Fixed the task timeout calculation to assure that there is
1113 never negative timeouts. The affected file is
1114 lib/silcutil/silcschedule.c.
1116 * Fixed the channel user mode notification sending in server.
1117 It was sent point-to-point to the router (or to server by router)
1118 but it needs to be destined to a channel. The routines now
1119 supports sending the channel user mode notifys to the channels
1120 when announcing clients and channels. Affected files are
1121 silcd/server.c and silcd/packet_receive.c.
1123 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1124 It did not actually replace the old channel entry in the cache.
1125 Affected file lib/silcclient/client_notify.c.
1127 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Fixed a possible crash in silc_packet_send_prepare. It now
1130 assures always that there is enough space in the buffer and
1131 at the tail area of the buffer (for MAC).
1133 Fixed the inbound buffer reallocation in silc_packet_read.
1134 It was old code and did not handle the reallocation correctly.
1137 The affected file is lib/silccore/silcpacket.c.
1139 * Fixed buffer overflow in silc_parse_nickname in the file
1140 lib/silcutil/silcutil.c.
1142 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * make install generates new server keys only if there is not
1147 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1149 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1150 Added check that if the NOREPLY is set then we will not send
1151 the away message. This avoids infinite loop of away messages
1152 if both clients are away. The affected file is
1153 lib/silcclient/client_prvmsg.c.
1155 * Fixed client crash if /NICK was given without arguments.
1156 Affected file lib/silcclient/command.c.
1158 * Server does not send the invite list in INVITE command back
1159 to the client if the list was not altered. Added this notion
1160 to the protocol spec as well. Affected file silcd/command.c.
1162 Fixed possible crash in INVITE command by checking the
1163 value of silc_server_get_client_route command.
1165 * Fixed the INVITE notify type handling. The arguments are now
1166 taken in correct order and client does not crash. The affected
1167 file is irssi/src/silc/core/silc-channels.c.
1169 Removed the "Inviting xxx to channel" message from the
1170 client library away and let the application handle it.
1171 Affected file lib/silcclient/command.c. Added that message
1172 to Irssi SILC client's message formats.
1174 * Fixed CMODE command crash in client. It now checks the
1175 amount of arguments correctly and does not crash. The affected
1176 file is lib/silcclient/command.c.
1178 * Do not create new channel automatically in silc_channels_join
1179 but check whether the channel by that name already exists.
1180 Affected file irssi/silc/core/silc-channels.c.
1182 * Do not send the SERVER_SIGNOFF to router if the disconnected
1183 entity was the router. Affected file silcd/server.c.
1185 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1186 SILC client as it was missing from there.
1188 Added the handling of the KICK notify to the Irssi SILC client
1189 as it was missing. Added "you have been kicked" message to
1190 Irssi SILC client's message modules formats.
1192 Added the handing of the KILL notify to the Irssi SILC client
1193 as it was missing. Added the kill message module formats
1196 The affected file is irssi/src/silc/core/silc-channels.c.
1198 * The router did not save the channel mode the server announced.
1199 Affected file silcd/packet_receive.c.
1201 * Fixed a possible crash in INFO command in server. If the
1202 server did not provide the server info it crashed. Affected
1203 file silcd/command.c.
1205 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Fixed the GETKEY command in the server to check also the
1208 global list. Otherwise the GETKEY would not work correctly
1209 in normal SILC server. Affected file silcd/command.c.
1211 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Fixed GETKEY crash, it crashed if the command did not succseed.
1215 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1217 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1218 is now real and not just an macro interface to GMP.
1220 Removed the entire GMP from the source tree and imported new
1221 NSS MPI library instead. Reason for removing GMP is that it is
1222 extremely large and compiles extremely slow. The NSS MPI
1223 is only a few files and compiles in less than 10 seconds.
1224 The speed is also about the same as GMP. The MPI is imported
1225 to lib/silcmath/mpi.
1227 If the system has GMP installed we will still use the GMP.
1228 If it is not then the NSS MPI will be compiled.
1230 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1232 * Merged a long nickname (127 characters long) crash bugfix from
1233 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1235 * Merged a freed memory reference bugfix from Irssi CVS tree.
1236 Affected file irssi/src/core/commands.c.
1238 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Added the server's public key sving and verification to the
1241 server when performing the SKE. This was missing and the
1242 remote server's (or router's) public key was accepted without
1243 checking whether we have it previously or trust it at all.
1244 Affected file silcd/protocol.c.
1246 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Check in the silc_server_timeout_remote if protocol is active
1249 and make sure that the protocol's final callback is called so
1250 that all memory if freed. Affected file silcd/server.c.
1252 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * silc_server_whois_send_reply crashed the server if the nickname
1255 was 127 characters long. Affected file silcd/command.c.
1257 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Added sanity check to the silc_server_new_client. If the hostname
1260 is provided inside username then check that the provided hostname
1261 really is the same as the resolved one. If the hostname was not
1262 resolved then check it from the public key. Affected file is
1263 silcd/packet_receive.c.
1265 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1266 if the server disconnected us and the connection is not valid
1267 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1269 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1270 the library to the lib/silcutil/silcutil.[ch].
1272 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1274 * Close log file after open. Affected file
1275 lib/silcutil/silclog.c.
1277 * Check whether sock == NULL in silc_client_send_packet and return
1278 if it is. Affected file lib/silcclient/silcclient.c.
1280 * Check rec->entry == NULL in the Irssi SILC Client before
1281 sending the channel message. Affecte file is
1282 irssi/src/silc/core/silc-servers.c.
1284 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Merged a splitted window bugfix from Irssi CVS tree. The
1287 affected file is irssi/src/fe-text/textbuffer-view.c.
1289 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1290 It did not print nickname.
1292 * Improved the distributions system a bit.
1294 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1297 irssi/src/fe-text/gui-window.c.
1299 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1300 to in-active server. The affected file is
1301 irssi/src/silc/core/client_ops.c.
1303 * Resolve the client in USERS command reply if the entry does
1304 not have username resolved. The affected file is
1305 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1306 command to WHOIS command to really resolve stuff. The USERS
1307 is not used any more in any critical section so WHOIS can
1308 be used even though it might be slower than IDENTIFY.
1310 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1313 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Changed the protocol API a bit more consistent in the
1316 lib/silccore/silcprotocol.[ch].
1318 * Changed the following headers to ROBODoc format:
1320 lib/silccore/silcpayload.h
1321 lib/silccore/silcprotocol.h
1322 lib/silccore/silcsockconn.h
1324 All core library headers are now formatted.
1326 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1328 * Fixed a bug in Irssi SILC client; do not show that you are
1329 server/router operator if you really are not. Affected file is
1330 irssi/src/silc/core/client_ops.c.
1332 * Renamed silc_command_free_payload to silc_command_payload_free.
1333 Affected file lib/silccore/silccommand.h
1335 * Added silcmath.h to include the prototoypes of various routines
1336 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1339 * Changed the following headers to ROBODoc format:
1341 lib/silccore/silcchannel.h
1342 lib/silccore/silccommand.h
1343 lib/silccore/silcid.h
1344 lib/silccore/silcidcache.h
1345 lib/silccore/silcmode.h
1346 lib/silccore/silcnotify.h
1347 lib/silccore/silcpacket.h
1348 lib/silcmath/silcmath.h
1350 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Added checking to the server code not to start the server if
1353 ciphers and stuff are not configured properly. Affected files
1354 silcd/serverconfig.[h] and silcd/server.c.
1356 * Changed the layout of the header files of the public interfaces
1357 in the SILC libraries. The new layout supports ROBODoc
1358 documentation tool (and some others) so that it is easy to create
1359 a library reference manual. All the other headers and source
1360 code must still follow the CodingStyle document. Also source
1361 code must not include these ROBODoc stuffs, only the headers.
1362 Furthermore, all public interface headers must now be named
1363 by using `silc' prefix, example: silcapi.h, silccipher.h.
1364 Some files were renamed due to this. All the other headers
1365 must not be used as public interfaces. I will update the
1366 CodingStyle document later. Changed following headers, so far:
1368 lib/silcclient/silcapi.h
1369 lib/silccore/silcauth.h
1370 lib/silccore/silcprivate.h
1371 lib/silccrypt/silcdh.h
1373 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Removed silc_client_packet_send_flush from the client library
1378 as it is not needed. Affected file lib/silcclient/client.[ch].
1380 * Added printing of message of unresolved authentication method
1381 to the Irssi SILC client. Added it to the module formats.
1382 Removed the same message from the client library.
1384 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1386 * Added new distribution feature, DISTLABEL. Every distribution
1387 can define own preprocessor label that can be used in the
1388 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1389 file distributions, acconfig.h.pre and prepare.
1391 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1393 * Added Makefile.defines_int to include the actual definitions
1394 for Makefile.defines.in. Tested the new distribution system,
1395 created distributions and tested installation.
1397 * Added AWAY message printing to the Irssi SILC client. Added
1398 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1400 * Added SCONNECT command to call the SILC's CONNECT command.
1401 Cannot use CONNECT directly since Irssi uses that internally.
1402 Affected file irssi/src/silc/core/silc-servers.c.
1404 Added ACTION local command. It is same as ME command but takes
1405 the channel as mandatory argument.
1407 Rewrote some of the Irssi's help files to suite for SILC
1410 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Added Makefile.defines[.in] that should for now on be included
1413 in all Makefile.am file in the source tree. That file includes
1414 all common compilation definitions for SILC source tree.
1416 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Minor changes to the ./prepare script to change the package
1419 name according the distribution name to the configure.in.
1421 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Created new distribution system. Added file `distributions'
1424 that defines all the distributions that can be created out of
1425 the SILC source tree. The ./prepare script now reads that
1426 file to determine how to prepare the distributions. The
1427 first argument to the ./prepare is the name of the distribution
1428 and second is the version of the distribution. If given
1429 without arguments it creates the default (toolkit) distribution
1430 with the default version (defined in ./prepare).
1432 All Makefile.am files that are subject to the distributions
1433 are now named as Makefile.am.pre. These are ./Makefile.am
1434 and lib/Makefile.am. Others may be changed later.
1436 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Added invite list, ban list, some key management and connection
1439 error message printing to module formats in the Irssi SILC client.
1441 * Added new silc_client_set_away_message to set the away message
1442 that is back to the person who sent private message. The
1443 affected file lib/silcclient/silcapi.h and the
1444 lib/silcclient/client_prvmsg.c.
1446 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Fixed the private message sending in the Irssi SILC client,
1449 added local command KEY to the Irssi SILC client.
1451 Added key management and key agreement message formats to the
1452 irssi/src/fe-common/silc/module-formats.[ch].
1454 Added USERS (alias WHO) printing, server/router operator
1455 indication and LIST command printing to the module formats.
1457 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1459 * Fixed channel joining notify handling, cumode notify handling
1460 from Irssi SILC client.
1462 * Added SILC specific module-formats to the Irssi SILC client so
1463 that SILC specific message hilighting, colors etc is possible.
1464 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1466 Added channel mode, channel user mode, actions, notices,
1467 whois and whowas printing to the the module-formats.c.
1469 * Fixed a bug in channel deletion in the server. The channel
1470 is not left to the cache even if the channel founder auth mode
1471 is set when there are no users anymore on the channel. Affected
1472 file silcd/server.c.
1474 * The silc_net_localhost now resolves the entire hostname including
1475 the domain name. Affected file lib/silcutil/silcnet.c.
1477 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1479 * Changed the ask_passphrase client operation to be ascynchronous.
1480 It has now a completion callback and a context that the
1481 application must call after it has got the passphrase from
1482 the user. Affected files lib/silcclient/silcapi.h,
1483 lib/silcclient/protocol.c, lib/silcclient/command.c and
1486 Added SilcAskPassphrase callback that the application calls
1487 to deliver the passphrase to the library.
1489 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1490 The public key verification and especially a certificate
1491 verification is asynchronous procedure.
1493 Added new SILC_SKE_STATUS_PENDING status to indicate the
1494 request is pending and a callback will be called to finalize
1497 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1498 indicate that remote end did not send its public key (or
1499 certificate), even though we require it. Added check for this
1500 condition in the SKE. This was a security bug, now fixed.
1502 Defined new SilcSKEVerifyCbCompletion callback that is called
1503 when the verification process is completed.
1505 The affected files lib/silcske/silcske_status.h and
1506 lib/silcske/silcske.[ch].
1508 * Changed the verify_public_key client operation to be async
1509 as well. Defined SilcVerifyPublicKey callback that is used to
1510 indicate the success of the public key verification process.
1512 Changed the server and client to use the new async client
1515 * Changed the Irssi SILC client's internal scheduler to be called
1516 twice as many times as it used to be. As a result the client
1517 should be a bit faster now. Affected file is
1518 irssi/src/silc/core/silc-core.c.
1520 * Added support to Irssi SILC client of asynchronous public key
1521 verification and passphrase inquiry. Affected file is
1522 irssi/src/silc/core/silc-core.c.
1524 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Do not say "You have left channel %s" in client library.
1527 Moved it to the application. Affected files are
1528 lib/silcclient/command.c and silc/client_ops.c.
1530 * Fixed silc_client_get_clients. Command context was not
1531 duplicated and was freed memory in the callback. Affected
1532 file lib/silcclient/idlist.c.
1534 * Do not say "you are now talking..." on JOIN command in the
1535 client library. The appliation must handle it.
1537 * Do not say ".. changed topic to" in command reply in the
1538 client libary. The application must handle it.
1540 * Fixed TOPIC command sending in the client library.
1542 * Fixed a memory leak in silc_client_command_free in the file
1543 lib/silcclient/command.c.
1545 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Imported a modified version of Irssi client to the source tree.
1548 The Irssi will be used to create a new client called
1549 Irssi SILC. Imported to irssi/.
1551 Added silc_core_init_finish function to the Irssi. Affected
1552 file irssi/configure.in.
1554 A lot changes in the Makefile.ams around the irssi tree.
1556 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Do not rehash if the new size is same as the old size of the
1559 hash table, in the silc_hash_table_rehash*. The affected file
1560 lib/silcutil/silchashtable.c.
1562 * Replaced hash_table_del_by_context calls from the server
1563 (when channel->user_list and client->channels) to the
1564 hash_table_del as it is sufficient and faster.
1566 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Added silc_hash_table_list, silc_hash_table_get and the
1569 SilcHashTableList structure to provide an alternative way to
1570 traverse the hash table. The affected files are
1571 lib/silcutil/silchashtable.[ch].
1573 * Changed the server's idlist routines to use the hash table
1574 routines to optimize the code.
1576 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Replaced the client entry's `channel' list and channel entry's
1579 `user_list' list to hash tables for optimized lookup. Changed
1580 the code to use the hash table interface around the code.
1581 Affected file lib/silcd/idlist.[ch].
1583 * Added `auto_rehash' boolean argument to the function
1584 silc_hash_table_alloc to indicate whether the hash table should
1585 auto-rehash when it thinks is appropriate time. It will
1586 increase the hash table size if the there is twice as much
1587 entries in the table than the size of the table, and will
1588 decrease the size if there are twice as less entries than
1589 the size of the table.
1591 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1595 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * silc_idcache_purge_by_context deletes the entry now by context
1598 as it is supposed to do. Affected file lib/silccore/idcache.c.
1600 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1601 client is not anymore valid (WHOWAS givens the info) and not
1602 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1604 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Removed the `data' and `data_len' arguments from the ID Cache
1607 interfaces and added `name' argument. ID Cache does not handle
1608 anymore the binary data only a names associated with given ID.
1610 * When hashing a Client ID with silc_hash_id the entire ID is
1611 not hashed anymore, instead only the hash of the Client ID is
1612 hashed. This way we can access the Client ID from the cache
1613 with Client ID but with the hash of the ID (which is a hash of
1614 the nickname) as well without any difference in performance.
1616 Added also silc_idcache_find_by_id_one_ext to do one on one
1617 searching when we have the actual ID. Added also function
1618 silc_hash_client_id_compare. The affected files are
1619 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1621 * When hashing the name associated with a ID it is always done
1622 in lowercase. This way we can access the cache without worrying
1623 about case-sensitivity, even though, for example nicknames are
1626 * Fixed a bug in server with channel message sending. It put
1627 wrong ID type as destination ID. The affected file
1628 silcd/packet_send.c.
1630 * silc_idcache_del_by_context now deletes from all hash tables
1631 by context. Affected file lib/silccore/idcache.c.
1633 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Changed the client library to use the new ID Cache interface.
1636 Changes around the source tree.
1638 * Added silc_hash_table_rehash_ext to rehash with specific
1639 hash function. Affected file lib/silcutil/silchashtable.[ch].
1641 * Added silc_hash_string_compare to compare two strings in the
1642 hash table. Affected file lib/silcutil/silcutil.[ch].
1644 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Added new function silc_idcache_del_by_context into the
1647 lib/silccore/idcache.[ch].
1649 * Changed the server's ID list routines to use the new ID Cache
1650 interface. Changes around the source tree.
1652 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1654 * Added silc_hash_table_del[_by_context]_ext functions in to the
1655 lib/silcutil/silchashtable.[ch].
1657 Removed silc_hash_table_find_all* routines and added new
1658 silc_hash_table_find_foreach to replace them.
1660 Added silc_hash_table_replace_ext function as extended
1661 replacing function. Separated the simple hash table interface
1662 from the extended hash table interface in the file
1663 lib/silcutil/silchashtable.h.
1665 * Fixed minor bugs and changed it to use some of the new
1666 hash table functions in lib/silccore/idcache.c
1668 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Added new function silc_hash_table_find_all to return all keys
1671 in the hash table by the specified key. As the hash table is
1672 collision resistant it also makes it possible to have several
1673 duplicate keys in the hash table. This function may be used to
1674 find all of the keys from the hash.
1676 Added user_context arguments to the SilcHashFunction,
1677 SilcHashCompare and SilcHashDestructor to deliver user specified
1680 Added new fuctions silc_hash_table_find[_all]_ext to do
1681 extended lookup with specified hash and compare functions and
1682 specified user contexts.
1684 Added new function silc_hash_table_add_ext to add the key
1685 with specified hash function and user context.
1687 Added new function silc_hash_table_foreach to traverse all
1688 entrys in the hash table. Added SilcHashForeach callback
1691 Added new function silc_hash_table_del_by_context to delete
1692 the entry only if the context associated with the key matches.
1694 Affected files are lib/silcutil/silchashtable.[ch].
1696 * Removed silc_hash_[server/client/channel]_id and added just
1697 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1698 silc_hash_id_compare to compare two ID's using as the hash table
1699 comparison function. Added also silc_hash_data to hash
1700 binary data and silc_hash_data_compare to compare it.
1702 * Removed silc_idlist_find_client_by_hash as it is not needed
1703 anymore. Affected file silcd/idlist.[ch].
1705 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1706 to use internally the SilcHashTable. The new ID Cache is a lot
1707 faster than the old one. Some of the ID Cache interface was also
1708 rewritten and obsolete and stupid functions were removed.
1710 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Added entry_count field to the SilcHashTable to keep the number
1713 of the entries in the table. Implemented the function
1714 silc_hash_table_rehash. Added new function
1715 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1717 Fixed a minor bug in silc_hash_table_free.
1719 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1720 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1721 into the lib/silcutil/silcutil.[ch].
1723 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1725 * Implemented a collision resistant hash table into the
1726 lib/silcutil/silchashtable[ch]. See the header and the source
1727 for the SilcHashTable API.
1729 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Merged dotconf version 1.0.2 into lib/dotconf.
1733 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Do not compile anything in lib/silcsim/* if the SIM support
1736 is not enabled. The tree should now compile without problems
1739 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Compiled the SILC under cygwin. Compiled and tested briefly
1742 without problems. More tests needed. The SIMs didn't compile
1745 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1747 * Fixed possible crash in silc_get_username in the
1748 lib/silcutil/silcutil.c.
1750 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Fixed a va_arg in silc/client_ops.c.
1754 * Oops, RC5 routines were named AES and caused some problems
1755 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1757 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1759 * Added new SilcIDIP structure into the lib/silccore/id.h and
1760 replaced the old `ip' fields from all SILC ID's to that type.
1761 This is a step towards IPv6 support.
1763 The silc_id_get_len takes now the ID as an extra argument.
1764 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1765 both IPv4 and IPv6 based ID's.
1767 The affected files are lib/silccore/id.[ch] and other files
1768 around the tree using these routines.
1770 * Removed the ID length arguments in server from various
1771 silc_server_send_notify_* routines -> they are not needed
1774 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Fixed memory leak in silc_encode_pem_file in the file
1777 lib/silcutil/silcutil.c.
1779 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Check minor version as well in the SKE. Affected files are
1782 silcd/protocol.c and lib/silcclient/protocol.c.
1784 * Added --identifier option to the server so that an identifier
1785 can be when creating the public key for the server. Affected
1786 file is silcd/silcd.c.
1788 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1789 lib/silccrypt/silcpkcs.c.
1791 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Register default ciphers and stuff when using -C option with
1794 the server. Affected file sildc/silcd.c.
1796 * Put back the servers public key filename format, it is better
1797 than the new one. For now, the client keys are saved with the
1798 new filename format. The affected file silc/client_ops.c.
1800 * Implemented the Cipher API for the rest of the ciphers that
1801 did not implement it or implemented it the wrong way.
1803 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Register default ciphers and stuff when using the -S option
1806 in the client. Affected file silc/silc.c. Same also when
1807 creating new key pair with -C option.
1809 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1811 * Fixed the silc_verify_public_key client operation function to
1812 save the public keys differently. The fingerprint is now
1813 used as filename and not the hostname. This way also the
1814 client keys are saved uniquely and not with hostnames. The
1815 affected file is silc/client_ops.c.
1817 * Trimmed the silc_hash_fingerprint function to remove extra
1818 whitespaces from the end of the fingerprint. The affected
1819 file is lib/silccrypt/silchash.c.
1823 * Added silc_cipher_register_default function to register all
1824 default ciphers. It can be used when configuration files
1825 does not exist and the application does not want any specific
1826 ciphers in any specific order.
1828 The SilcDList is now used as silc_cipher_list dynamically
1829 allocated cipher list. Removed the static list all together
1830 and now all ciphers must be allocated to the dynamic list.
1831 The silc_cipher_alloc routine was changed to check only the
1834 All silc_cipher_* routines that used to return int returns
1837 The affected files lib/silccrypt/silccrypt.[ch].
1839 * The same thing was done to silc_hash_* as for silc_cipher_*
1840 routines. Affected files lib/silccrypt/silchash.[ch].
1842 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1843 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1844 Added also silc_pkcs_[un]register[_default] functions.
1845 Removed the data_context from the PKCS API.
1847 * Added silc_hmac_register_default function to register default
1848 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1849 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1850 to unregister all hmacs at once.
1852 * Register the default ciphers, hash functions, PKCSs and HMACs
1853 if client's configuration file does not exist. The affected
1856 * The client did not load the hash functions from the SIM
1857 modules at all. Added support for this. Affected file is
1858 silc/clientconfig.c.
1860 * When decoding public key with silc_pkcs_public_key_decode, check
1861 the supported algorithm only if PKCS are registered. Affected
1862 file lib/silccrypt/silcpkcs.c. The same was done with the
1863 silc_pkcs_private_key_decode.
1865 * Fixed the SILC List routines to keep the list always in order.
1866 It used to change the list's order when traversing the list but
1867 not it preserves the order. Affected file lib/trq/silclist.h.
1869 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1871 * Added the client library to use the SilcSocketConnection's
1872 reference counter (by silc_socket_dup) to prevent the bug that
1873 the socket object may be freed underneath async operation.
1875 * The name resolv library checking fixes in the configure.in.pre.
1878 * Created new version of the protocol drafts for future
1879 development. The -03 drafts are the ones that will be changed
1880 in the trunk now and the -02 will remain as they are.
1882 * Send list of CUMODE notifys to the router when announcing
1883 the channel users to the router. Affected file silcd/server.c.
1884 If the router receiving channel founder CUMODE for a channel
1885 that already has channel founder it will send CUMODE notify
1886 to the sender to remove the channel founder rights from the
1887 announced client. Affected file silcd/packet_receive.c.
1889 * The CUMODE notify may now use Server ID as well as the entity
1890 who changes the mode. Updated protocool specs.
1892 * Updated INSTALL and README files.
1894 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * New web pages in the http://silc.pspt.fi. The pages was
1901 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Implemented the [DenyConnectin] config section in the server.
1904 Added silc_server_config_denied_conn to check whether incoming
1905 connection is denied. Affected file silcd/serverconfig.[ch].
1907 * Do not check the ports when checking the incoming configuration
1908 data if the port is 0, meaning any. Affected file is
1909 silcd/serverconfig.c.
1911 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Fixed buffer overflow in silc_string_compare in the file
1914 lib/silcutil/silcutil.c.
1916 * Fixed double free in silc_server_command_leave in the file
1919 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Fixed the version checking in the server. Affected file is
1924 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Fixed the configuration data fetching when accepting new
1927 connections in the server. Affected file silcd/server.c.
1929 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1931 * Added `sender_entry' argument to the function
1932 silc_server_packet_relay_to_channel so that we can check
1933 whether some destination actually belongs to the same route
1934 the sender belongs (ie, we must not resend the packet to the
1935 sender). Affected file silcd/packet_send.[ch].
1937 * Added `servername' field to the SilcClientEntry in the server
1938 to hold the name of the server where client is from. Affected
1939 file is silcd/idlist.h.
1941 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Moved the channel message encrypting in the router betwen
1944 router connections from silc_server_channel_message to the
1945 silc_server_packet_relay_to_channel since we want to check
1946 whether we have anybody channel before encrypting anything.
1947 Affected files silcd/packet_[receive/send].c.
1949 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Fixed the [AdminConnection] server config section to support
1952 multiple entries. Affected file silcd/serverconfig.c.
1954 * Added support into the server to check the validity of the
1955 incoming connection before executing any KE or authentication
1958 * The connection configuration is now saved to the KE and
1959 connection auth protocol contexts and not fetched anymore in
1960 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1962 * The local hosts listenning address and port is also resolved
1963 now when starting the server. We want to have the socket object
1964 to include the real address and port for the listener. Added
1965 new function silc_net_check_local_by_sock into the files
1966 lib/silcutil/silcnet.[ch].
1968 * Fixed a broadcast bug in server -> do not broadcast if we
1971 * Fixed a routing bug. Do not route broadcast packets ever.
1972 Broadcast packets must be processed always and not routed since
1973 they may be destined to some other host than yourself and thus
1974 would get routed without no good reason. Affected file is
1977 * Added function silc_server_config_is_primary_route to check
1978 whether primary router connection has been configured (a router
1979 configuration that we are initiating). If there is not, we
1980 will assume that there is only two routers in the SILC network
1981 and we will use the incoming router connection as our primary
1982 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1984 * Changed the order of the broadcasting. Broadcast _after_ the
1985 packet has been processed not before. Affected file is
1988 * Fixed a [ClientConnection] parsing bug. The port was never
1989 parsed correctly thus resulting to port 0. Affected file
1990 silcd/serverconfig.c.
1992 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1993 argument and did not set the broadcast packet flag. Affected
1994 file silcd/packet_send.c. Fixed same bug in the function
1995 silc_server_send_notify as well.
1997 * If we receive NEW_ID packet for our own ID in the server, ignore
2000 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2004 * Removed the nickname from the Private Message Payload.
2005 Updated the code and the protocol specs.
2007 * Updated protocol specs for submitting to the IETF.
2009 * Tweaked the Random Number Generator a bit. Affected file
2010 lib/silccrypt/silcrng.c. Exported a new function
2011 silc_rng_[global]_add_noise which can be used to add more
2014 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Do not parse packets with different timeout when protocol
2017 is active -> may cause problem with rekey. Affected file
2020 * When server receives signoff notify it must not create
2021 new channel key if the client is on any channels since the
2022 sender of the signoff notify will create it.
2024 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Added printing of error messages during SKE protocol from the
2027 failure packet sent by server during SKE. Affected file
2030 * Removed the client's failure_callback handling with timeout
2031 and handle it immediately when received.
2033 * The SKE library returned wrong type in SUCCESS and FAILURE
2034 packets. They must be 32 bit MSB not 16 bit MSB.
2036 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Ok, rewrote the logic of the re-key and now it seems to work.
2039 I tested it on high traffic with frequent re-keys without
2040 problems. Added hmac_receive (and renamed hmac to hmac_send)
2041 in SilcClientConnection in lib/silcclient/client.h and
2042 in SilcIDListData in silcd/idlist.h. Also, removed the
2043 SilcPacketParserContext's cipher and hmac fields as they are
2044 not needed anymore and actually caused some problems when
2045 the ciphers and hmac's changed underneath the packet parser.
2047 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * If re-key protocol is active then process the incoming packets
2050 synchronously since we must assure that icoming packets encrypted
2051 with the old key is processed before the new keys is set to
2052 use. This is true other packets than for REKEY packets.
2053 Affected file silcd/server.c. The same was done to client library
2054 as well, affected file lib/silcclient/client.c.
2056 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Fixed bug in client and server to accept the force send if
2059 the packet is send from silc_[server/client]_packet_process
2060 function. Otherwise the packets are never delivered, oops.
2062 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Disable force sending of packets when REKEY protocol is active.
2065 We must assure that no packet is sent directly when rekey is
2066 performed. All packets must be sent through packet queue.
2067 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2068 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2069 function is silc_[server/client]_packet_send_real to check
2072 * Replaced the SIM paths from example config files to
2073 /usr/local/modules. Also, make install creates now
2074 /usr/local/silc/logs directory to hold all the SILC server
2077 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Made the configure.in.pre work on Solaris. Patch by salo.
2081 * Made all ciphers compatible with non-x86 machines. Defined
2082 CBC mode macros into lib/silccrypt/ciphers_def.h.
2084 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Fixed the make install.
2088 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * When MAC computation fails the silc_packet_decrypt returned 0
2091 even though it was supposed to return -1. Fixed this. The
2092 affected file is lib/silccore/silcpacket.c.
2094 * Do not replace the config files in /etc/silc (in make install)
2095 if they already exist. Affected file ./Makefile.am.
2097 * Do not send re-key packets immediately but through packet queue.
2098 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2100 * Changed silc_net_check_host_by_sock to return FALSE if the
2101 IP/DNS could not be resolved. Though, it returns the IP address
2102 now even if it could not resolve it (but returns also FALSE).
2103 Affected file lib/silcutil/silcnet.[ch].
2105 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Added silc_pkcs_decode_identifier to decode the public key's
2108 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2109 Added also silc_pkcs_free_identifier. Added also new context
2110 SilcPublicKeyIdentifier.
2112 * Added -S option to the silc client. It is used to dump the
2113 contents of the specified public key file.
2115 * Changed the PKCS api to return the public key length when
2116 setting the public key.
2118 * Fixed a fatal bug in the public and private key file loading.
2119 Affected file lib/silccrypt/silcpkcs.c.
2121 * Execute the packet parsing for client with zero (0) timeout
2122 if the protocol is active. Affected file silcd/server.c.
2124 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Made the key generation options to the silcd program. Added
2127 -C option, equivalent to client's option.
2129 * Added new [ServerKeys] config section to the server. It
2130 configures the server's public and private key.
2132 * Defined generic Public Key Payload into the protocol
2133 specification to send specific type of public keys and
2136 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2137 public key or certificate.
2139 * Implemented the GETKEY command to the server and to the
2140 client library and on user interface.
2142 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Made preliminary `make install' work.
2146 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Added SilcServerRekey context into silcd/idlist.h.
2150 * Added the PFS support as defined in the specification to the
2151 SKE protocol. Affected files lib/silcske/*.c.
2153 * Added `ske_group' field to the SilcServerRekey context to hold
2154 the number of the SKE group that is used with PFS in re-key.
2155 Affected file silcd/idlist.h.
2157 * Added PFS re-key support to the server. Affected file is
2160 * Added silc_protocol_cancel to cancel execution of the next
2161 state of the protocol. Affected file is
2162 lib/silccore/silcprotocol.[ch].
2164 * Added the re-key support with and without PFS to the client
2165 library. Re-key is performed once in an hour, by default.
2167 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2168 Added silc_client_rekey_callback and silc_client_rekey_final.
2169 Affected files are lib/silcclient/protocol.[ch] and
2170 lib/silcclient/client.[ch].
2172 * Removed the `hmac_key' and `hmac_key_len' fields from the
2173 SilcClientConnection structure; not needed. Affected file is
2174 lib/silcclient/client.h.
2178 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2180 * Do not ask whether user wants to use the negotiated private key
2181 for private messages, just use it. Affected file is
2182 silc/local_command.c.
2184 * Added `send_enc_key' and `enc_key_len' fields to the
2185 SilcIDListData structure since they are needed in the re-key
2186 phase. Affected file is silcd/idlist.[ch].
2188 * Implemented the simple re-key protocol into the server.
2189 Affected files silcd/server.c and silcd/protocol.[ch]. The
2190 re-key will be performed once in an hour, by default.
2192 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2193 Added silc_server_rekey, silc_server_rekey_callback and
2194 silc_server_rekey_final.
2196 * Removed Tunneled flag from the protocol. Updated the code
2197 and the specifications.
2199 * Adde `pfs' field to the SilcIDListData to indicate whether
2200 the PFS is to be performed in the re-key. Affected file is
2203 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2206 int64 of at least the xintXX size. If void * is less that 4
2207 bytes uint32 * will be used. Defined bool as boolean.
2209 * Changed _ALL_ unsigned long and unsigned int to uint32,
2210 unsgined short to uint16 in the source tree.
2212 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2213 not handle clients that has entry->data.registered == FALSE.
2214 They are not in the network anymore. Affected file is
2217 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Implemented the sending of the SERVER_SIGNOFF notify in the
2220 server. Affected file is silcd/server.c.
2222 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2223 Added also silc_notify_payload_encode_args into the
2224 lib/silccore/silcnotify.[ch].
2226 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2227 Affected file silcd/packet_receive.c.
2229 * Implemented the SERVER_SIGNOFF notify handling in the client
2230 library. Affected file lib/silcclient/client_notify.c. Also,
2231 implemnted the printing of the SERVER_SIGNOFF info to the
2232 application. Affected file silc/client_ops.c.
2234 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2235 if the deleting was successful. Affected file silcd/idlist.[ch].
2237 * Added support for public key authentication in the connection
2238 authentication protocol in the client library. Affected file
2239 lib/silcclient/protocol.c.
2241 * Changed the server's silc_idlist_get_clients_by_* interface
2242 to support already allocated array so that new entries may be
2243 added to pre-allocated array. Affected file silcd/idlist.[ch].
2244 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2245 and command replies.
2247 * All command reply functions in the server now calls the
2248 pending command callback even if error occured. This way the
2249 error will be delivered to the client as well. Affected files
2250 silcd/command.c and silcd/command_reply.c.
2252 * Fixed INFO command to return local server's info if no server
2253 was provided. Affected file lib/silcclient/command.c.
2255 * Removed RESTART command for good. Updated the code and the
2258 * Rewrote parts of the task system. It is a bit simpler now.
2259 Removed unsued task priorities. The affected files are
2260 lib/silcutil/silctask.[ch].
2262 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Moved the USERS printing from the library to the application.
2265 Affected files lib/silcclient/command.c and silc/client_ops.c.
2267 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Added channel key re-key support. The re-key is perfomed
2272 only by the router and is done once in an hour. Added `rekey'
2273 field to the SilcChannelEntry in the server. Affected files
2274 silcd/server.c and silcd/idlist.h.
2276 * Added silc_task_unregister_by_context into the file
2277 lib/silcutil/silctask.[ch].
2279 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Added SILC_UMODE_GONE mode to indicate when the client is not
2282 present in the SILC network. Added also support to the local
2283 command AWAY that will set this mode. Added support of showing
2284 "xxx is gone" in WHOIS command. The USERS command shows the
2285 gone status as well.
2287 * Fixed setting server and router operator privileges in the
2288 server's UMODE command. Affected file silcd/command.c.
2290 * Merged the SKE KE1 and KE2 payloads into one payload. The
2291 new KE payload is equivalent to the old KE2 payload.
2293 Cleaned up the SKE Start Payload parsing. It now uses the
2294 simple buffer unformatting to do the parsing. A lot faster
2297 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2298 to the SKE that is used to indicate whether both of the SKE
2299 parties should perform authentication. By default only the
2300 responder performs authentication. By setting this flag also
2301 the initiator must do authentication. By default it is unset
2302 since in normal SKE case, client to server connection, only
2303 the responder should do authentication. When doing SKE between
2304 two clients both should perform authentication. Updated the
2305 code and the protocol specs.
2307 * A little fix to IDENTIFY command in the server. Search the
2308 client first by hash not nickname. Affected file is
2311 * Fixed the silc_client_close_connection to support closing
2312 the client to client connections wihtout deleting too much
2313 data. Affected file lib/silcclient/client.c.
2315 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2316 are received if protocol used to be active but is not anymore
2317 the application would crash due to NULL pointer dereference.
2318 Affected files silcd/server.c and lib/silcclient/client.c.
2320 * Added `hash' field to the SilcClientConnection to include
2321 the hash function negotiated in the SKE protocol.
2323 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2324 to set the channel founder authentication data. A client can
2325 claim the founder rights later by providing the authentication
2326 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2327 This way the channel founder can regain the channel founder
2328 privileges even it is left the channel. This works only on
2329 local server and the client must be connected to the same
2330 server to be able to regain the founder rights. Updated the
2331 protocol specs accordingly.
2333 Added support to the CMODE command in the client to set the
2334 founder auth data. Read the README to see how to set it.
2336 Added support to the CUMODE command to claim the founder
2337 rights. Read the README to see how to do it.
2339 Added support for the founder authentication to the Channel
2340 Entry in the server. Affected file silcd/idlist.h.
2342 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2343 server's CMODE command. Affected file silcd/command.c.
2345 * Added the following new functions into lib/silccore/silcauth.[ch]:
2346 silc_auth_get_method and silc_auth_get_data.
2348 * The server now saves the remote hosts public key to the
2349 SilcIDListData pointer. Affected file silcd/protocol.c.
2351 * The normal server now does not remove the channel entry from
2352 the cache if the founder authentication data is set. It used
2353 to remove it if the founder was the last one on the channel on
2354 the server and left the channel. The auth data is saved and
2355 if the channel is re-joined later the old entry is used with
2356 the old auth data. Affected files silcd/command_reply.c and
2359 * Removed the `pkcs' field from the SilcIDListData structure
2360 in the server; it is not used. Affected file silcd/idlist.h.
2362 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Fixed packet processing on slow links. Partial packets were
2365 never re-processed because the incoming data buffer was cleared
2366 by the application. Application must not directly clear the
2367 sock->inbuf, the packet processing routines handle it. Fixed
2368 this in client library and in server.
2370 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2372 * Fixed the WHOIS and IDENTIFY send reply function to really
2373 check whether to send list or just one entry. Affected file
2376 * Cleaned up the LEAVE command's channel key distribution. The
2377 affected file silcd/command.c.
2379 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2380 can enforce the channel mode as well. In that case the ID
2381 includes the ID of the server. The code now enforces the
2382 mode change if the router have different mode than the server.
2384 * The notify client operation with CMODE_CHANGE notify can now
2385 return NULL client_entry pointer if the CMODE was not changed
2386 by client. Application must check for this.
2388 * Added <Server ID> argument to INFO command to support server
2389 info fetching by Server ID.
2391 * Added silc_server_announce_get_channel_users to get assembled
2392 packets of channel users of the specified channel. Affected
2393 file silcd/server.[ch].
2395 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2396 was freed underneath the ID Cache.
2398 * Re-announce clients when the server received CHANNEL_CHANGE
2399 notify from the router. Affected file silcd/packet_send.c.
2401 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2404 crashed since it did not handle the fact that there is no cipher
2405 called "3" and didn't check the error condition. Now fixed.
2407 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2408 flag. It can be used to send message requests.
2410 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Implemented the RESTART command in the client.
2414 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2415 notice type messages. Added notice printing to the user
2418 * The channel keys are not re-generated if the channel's mode
2419 is PRIVKEY, ie private key on the channel exists. Affected
2420 files silcd/server.c and silcd/command.c.
2422 * Fixed a little bug in channel message delivery when channel
2423 private keys are set in the server. Affected file is
2424 silcd/packet_send.c.
2426 * Changed the setting on channel->on_channel = TRUE from the
2427 silc_client_save_channel_key to the JOIN command reply. The
2428 key payload is not received if the private channel key is set.
2429 Affected file lib/silcclient/command_reply.c and the
2430 lib/silcclient/client_channel.c.
2432 * When the CMODE_CHANGE notify is sent and the channel private
2433 key mode is removed the channel key must be re-generated in
2434 other cells as well. Added this support for the router in the
2435 silcd/packet_receive.c.
2437 * Added new local command NOTICE to send notice message on
2438 channel. Affected file silc/local_command.[ch].
2440 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Added new local command ME to the client. It is used to send
2443 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2444 some action. Affected file silc/local_command.[ch].
2446 * Changed channel_message and private_message client operations
2447 to deliver the message flags to the application. Added also
2448 the `flags' arguments to the silc_client_send_channel_message
2449 and silc_client_send_private_message functions. Affected file
2452 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Redefined the Private Message Payload to support private message
2455 keys and to support the new private message flags. Updated
2456 the protocol specs. Flags makes it possible to have for example
2457 CTCP style messages.
2459 * Added new type SilcPrivateMessagePayload and defined an API
2460 for it in the lib/silcclient/silcprivate.[ch].
2462 * Tested private message private keys successfully. Tested the
2463 private message key set, unset and list commands with the new
2466 * Redefined the Channel Message Payload to include the channel
2467 message flags (equal with private message flags) to support
2468 for example CTCP style messages.
2470 * Defined some of the message (for channel and private message)
2471 flags. Updated the protocol specs and added the flags to the
2472 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2474 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Added SilcKeyAgreementStatus type to the key agreement routines
2477 to indicate the current status and error if one occured.
2478 The status types are defined in the lib/silcclient/silcapi.h.
2480 * Added new local command KEY that is used to set and unset private
2481 keys for channels, set and unset private keys for private messages
2482 with remote clients and to send key agreement requests and
2483 negotiate the key agreement protocol with remote client. The
2484 key agreement is supported only to negotiate private message keys,
2485 it currently cannot be used to negotiate private keys for channels,
2486 as it is not convenient for that purpose.
2488 * Fixed a minor pending callback setting bug in the function
2489 silc_client_get_client_by_id_resolve, now the function works.
2490 Affected file lib/silcclient/idlist.c.
2492 * Added function silc_net_get_local_port to get local bound
2493 port by socket. Added to lib/silcutil/silcnet.[ch].
2495 * Added `sockets' and `sockets_count' fields to the SilcClient
2496 object. They hold the sockets of the listenning sockets in
2497 the client. Listenning sockets may be for example the key
2498 agreement server. Affected file lib/silcclient/client.[ch].
2499 Added functions the silc_client_add_socket and the
2500 silc_client_del_socket. They are exported to the application
2503 * Added ~./silc/clientkeys to support other client's public keys.
2505 * Renamed verify_server_key client operation to verify_public_key
2506 and added one argument to indicate the type of the connection
2507 (server, client etc.).
2509 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Added silc_server_connection_auth_request to handle the
2512 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2513 silcd/packet_receive.[ch].
2515 * Added silc_server_send_connection_auth_request into the
2516 silcd/packet_send.c to send the connection auth request packet.
2518 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2521 * Fixed the public key authentication in responder side in the
2522 server. The `auth_data' pointer includes the SilcPublicKey
2523 not the path to the public key. Affected file silcd/protocol.c.
2525 * Implemented the public key authentication in the initiator side
2526 in the server. Affected file silcd/protocol.c.
2528 * Removed the [RedirectClient] config section from the server
2529 configuration. Is not needed and I don't want to implement it.
2531 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Cleaned up the CMODE command in the server. It now works
2534 correctly and supports all the modes defined in the protocol.
2535 Affected file is silcd/command.c.
2537 * Added `hmac_name' field to the SilcChannelEntry in the server
2538 to hold the default HMAC of the channel. It can be set when
2539 creating the channel (with JOIN command). Affected files
2542 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2543 type to indicate the change of the current cipher and hmac
2544 on the channel. Client can safely ignore the <cipher> argument
2545 (if it chooses to do so) since the CHANNEL_KEY packet will
2546 force the channel key change anyway. The <hmac> argument is
2547 important since the client is responsible of setting the new
2548 HMAC and the hmac key into use.
2550 * Fixed the CMODE command in the client library as well.
2552 * Tested CMODE command in router environment successfully.
2554 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Show the version of the remote client (or server) when connecting
2557 to the server. It is logged to the log file. Affected file
2558 is silcd/protocol.c.
2560 * Fixed the KILLED notify handling in the client library. The
2561 client must be removed from all channels when receiving the
2564 Also, do not remove the client entry when giving the KILL
2565 command but when the KILLED notify is received.
2567 * Removed silc_idlist_find_client_by_nickname from the server.
2568 Not needed anymore. Affected files silcd/idlist.[ch].
2570 * Implemented the CHANNEL_CHANGE notify type handling to the
2571 server. Affected file silcd/server.c.
2575 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Added silc_server_send_notify_invite to send the INVITE
2578 notify between routers.
2580 * Implemented the INVITE command correctly to the server.
2582 * Implemented the INVITE notify type handling in the server.
2584 * Implemented the INVITE command to the client library and on the
2587 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Added function silc_server_get_client_resolve to find the
2590 client entry by ID from all ID lists and then resolve it
2591 (using WHOIS) if it cannot be found. Affected file is
2594 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Implemented the BAN command to the client library.
2598 * The JOIN command in the server now checks the invite list
2601 * Changed the silc_command_reply_payload_encode_va and the
2602 silc_command_payload_encode_va to support that if argument is
2603 NULL it ignores and checks the next argument. Affected file
2604 lib/silccore/silccommand.c.
2606 * Added silc_server_send_notify_ban to send the BAN notify
2607 type between routers.
2609 * Chaned the silc_notify_payload_encode to support that if
2610 argument is NULL it ignores and checks the next argument.
2611 Affected file lib/silccore/silcnotify.c.
2613 * Tested ban lists in router environment successfully.
2615 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Implemented BAN command to the server, in silcd/command.[ch].
2619 * Removed the BAN and INVITE_LIST modes from the CMODE command
2622 * Added function silc_string_match to regex match two strings.
2623 Affected files lib/silcutil/silcutil.[ch].
2625 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Redefined parts of the SilcChannelEntry in the server to support
2628 the new ban and invite lists.
2630 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Redefined the INVITE command. The same command can be used to
2633 invite individuals to the channel but also to manage the invite
2634 list of the channel (to add to and remove from the invite list).
2635 Updated the protocol specs.
2637 * Added new command SILC_COMMAND_BAN that can be used to manage
2638 the ban list of the channel. Updated the protocol specs.
2640 * Removed the channel modes: the SILC_CMODE_BAN and the
2641 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2642 in the CMODE command. The equivalent features are now available
2643 using INVITE and BAN commands. Updated the protocol specs.
2645 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2646 in the network about change in the current ban list. The notify
2647 type is not used by the client.
2649 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2650 support the invite lists.
2652 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Added new function silc_string_regexify that converts string
2655 including wildcard characters into regex string that can
2656 be used by the GNU regex library. Added into the file
2657 lib/silcutil/silcutil.[ch].
2659 Added silc_string_regex_combine to combine to regex strings
2660 into one so that they can be used as one regex string by
2661 the GNU regex library. Added into the file
2662 lib/silcutil/silcutil.[ch].
2664 Added silc_string_regex_match to match two strings. It returns
2665 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2667 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Imported GNU regex to the soruce tree into lib/contrib.
2670 Fixed some compiler warning from the regex.c.
2672 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2674 * Fixed MOTD command in the server to work in router environment.
2676 * Fixed the MOTD command in the client library to support
2677 the server argument in the command.
2679 * Added `nickname_len' argument to the silc_idlist_add_client
2680 in the server, as the `nickname' argument may be binary data
2683 * Added silc_idlist_get_channels to return all channels from
2686 * Implemented LIST command to the server. Affected file is
2689 * Implemented the LIST command to the client library and on the
2692 * Added [<user count>] argument to the LIST command reply.
2693 With private channels the user count is not shown.
2695 * Updated TODO and README.
2697 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * The client entry's data.registered must be TRUE even with
2700 global client entry on global client list. The data.registered
2701 is used to check whether the client is anymore in the network,
2702 for example with WHOWAS command so it must be valid.
2704 * Fixed the WHOWAS command in the server. It now actually works
2705 in router environment. Added function into silcd/command_reply.c
2706 silc_server_command_reply_whowas_save.
2708 * Added silc_idlist_purge function to the silcd/idlist.c
2709 to periodically purge the ID Cache.
2711 * Fixed INFO command in the server. It works now in router
2712 environment. Added <server name> argument to the INFO command
2713 reply. Updated the protocol specs.
2715 * Fixed minor bug in silc_idcache_purge to not purge if the
2716 expire value is zero.
2718 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2719 they were buggy because of the WHOWAS information.
2721 * Fixed local command MSG to handle the async resolving of
2722 the remote client properly. It used to fail the first MSG.
2723 Affected file silc/local_command.c.
2725 * Added `data_len' field to SilcIDCache context.
2727 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Update TODO. Todo in commands in the server.
2731 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2734 used by routers as broadcast packet to inform other routers
2735 about the changed user mode.
2737 Implemented the notify handling in the server. Affected file is
2738 silcd/packet_receive.c. Added the function
2739 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2741 * Added new generic Channel Payload and deprecated the New Channel
2742 Payload. The New Channel Payload is now the generic Channel
2745 * Added new argument `mode' to the silc_server_send_new_channel
2746 as it is required in the Channel Payload now.
2748 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2749 and created a new and real SilChannelPayload to represent the
2750 new generic Channel Payload. Implemented the encode/decode
2751 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2753 * Added silc_server_get_client_channel_list to return the list
2754 of channels the client has joined for WHOIS command reply.
2755 Affected file silcd/server.[ch].
2757 * Implemented the channel list sending in the WHOIS command reply
2758 in server and in the client.
2760 Implemented the channel list displaying on the user interface
2761 as well. Affected file silc/client_ops.c.
2763 * Added silc_channel_payload_parse_list to parse list of Channel
2764 Payloads. It returns SilcDList list of SilcChannelPayloads.
2765 Client for example can use this function to parse the list of
2766 channels it receives in the WHOIS command reply. The caller
2767 must free the list by calling silc_channel_payload_list_free.
2768 Affected files lib/silccore/silcchannel.[ch].
2770 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Added one new argument <user mode> to the WHOIS command reply
2773 to return the mode of the user in SILC. Updated the protocol
2776 Implemented it to the server and client.
2778 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2780 * Fixed the mode printing on the user interface on joining.
2781 Affected file silc/client_ops.c.
2783 * Implemented the UMODE command and user modes in general to the
2784 client library and to the user interface.
2786 * Implemented the UMODE command to the server.
2788 * The server now sends UNKNOWN_COMMAND error status if client sends
2789 unknown command. Affected file silcd/command.c.
2791 * All server commands now handle the command identifier the right
2792 way when sending the command reply to the client. The client can
2793 use to identify the command replies with the identifier.
2795 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Added silc_server_get_client_route to resolve the route to
2798 the client indicated by the client ID. Affected file is
2801 * Added silc_server_relay_packet as general function to relay
2802 packet to arbitrary destination. This deprecates functions
2803 like _send_private_message_key, _relay_notify etc. Affected
2804 file is silcd/packet_send.[ch].
2806 Removed silc_server_send_key_agreement,
2807 silc_server_send_private_message_key and
2808 silc_server_packet_relay_notify functions from the file
2809 silcd/packet_send.[ch].
2813 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2814 server. Affected file silcd/packet_receive.[ch].
2816 * Implemented the KILL command to the client. Implemented the
2817 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2818 Affected files lib/silcclient/command[_reply].c and
2819 lib/silcclient/client_notify.c. Implemented the KILL notify
2820 printing in the user inteface.
2822 * Fixed a lot silc_parse_nick memory leaks from the client
2823 library in the file lib/silcclient/command.c.
2825 * Changed the silc_server_send_notify_on_channels's `sender'
2826 argument from SilcSocketConnection to SilcClientEntry to
2827 check the sender as entry and not as connection object and not
2828 to send to the client provided as argument. The affected file
2829 is silcd/packet_send.[ch].
2831 * The notify packets that are destined directly to the client used
2832 to not to be processed by the server. Now changed that and the
2833 server processes all notify packets. After relaying the packet
2834 to the client the notify packet is processed in the server.
2836 * The silc_server_free_client_data now checks whether there is
2837 pending outgoing traffic for the client and purges the data to
2838 the network before removing the client entry.
2840 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2843 an client is killed from the SILC Network. Updated the protocol
2846 Added new function silc_server_send_notify_killed to the
2847 silcd/packet_send.[ch].
2849 * Added function silc_server_packet_relay_notify to relay notify
2850 packets that are destined directly to a client. In this case
2851 the server does not process the notify packets but merely relays
2852 it to the client. Affected file silcd/packet_send.[ch].
2854 Added also silc_server_packet_process_relay_notify to check
2855 whereto relay the notify. Affected file is
2856 silcd/packet_receive.[ch].
2858 * Implemented the KILL command to the server.
2862 * Added the backup schema desgined last fall to the protocol
2863 specs for everyone to see. The specification is in the
2864 *-spec-xx.txt draft and the packet type definitions for the
2865 backup routers is in *-pp-xx.txt draft. Thusly, added also
2866 new packet type SILC_PACKET_CELL_ROUTERS.
2868 * A big security problem in the implementation discovered. The
2869 signoff of an client did not cause new channel key generation
2870 which it of course should've done. The channel keys must be
2871 always re-generated when client leaves (or signoffs) the channel.
2872 The silc_server_remove_from_channels funtion now handles
2873 the channel key re-generation.
2875 * Added `sender' argument to the silc_server_send_notify_on_channels
2876 to not to send the client provided as argument. Affected file
2877 silcd/packet_send.[ch].
2879 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Implemented OPER and SILCOPER commands into the server and
2884 * Added silc_auth_verify and silc_auth_verify_data to verify
2885 the authentication directly from the authentication payload.
2886 It supports verifying both passphrase and public key based
2887 authentication. Affected file lib/silccore/silcauth.[ch].
2889 * Added `hash' field to the SilcIDListData structure. It is the
2890 hash negotiated in the SKE protocol. Affected file is
2893 * Slight redesigning of the SilcAuthPayload handling routines.
2894 Do not send SilcPKCS but SilcPublicKey as argument.
2896 * Implemented the public key authentication support to the
2897 serverconfig. The public key is loaded from the provided path
2898 and saved as authentication data to void * pointer. Thus,
2899 changed the unsigned char *auth_data to void *auth_data;
2901 * Fixed SHUTDOWN command to send the reply before the server
2902 is shutdown. :) Affected file silcd/command.c.
2904 * Fixed fatal bug in CONNECT command. The hostname was invalid
2905 memory and server crashed. Affected file silcd/command.c.
2907 * Fixed fatal bug in CLOSE command. The server_entry became
2908 invalid but was referenced later in the command. Affected file
2911 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2913 * Fixed fatal bug in failure packet handling. Server ignored
2914 the failure and thus crashed when it came.
2918 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2921 that the command may be executed only once in (about) 2 seconds.
2922 The old SILC_CF_LAG flag is same but allows command bursts up
2923 to five before limiting.
2925 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2926 server code. Various commands now includes the CF_LAG_STRICT
2927 flag to disallow any kind of miss-use of the command.
2929 * Fixed the silc_buffer_unformat to not to allocate any data
2930 if the length of the data is zero. It used to allocate the
2931 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2933 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2935 * Changed the format of AdminConnection configuration section
2936 in the server. Added username of the admin to the format.
2937 Affected files silcd/serverconfig.[ch].
2939 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2940 to return admin configuration data by host, username and/or
2943 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Implemented WHOWAS command to the server. Added the functions:
2947 silc_server_command_whowas_parse,
2948 silc_server_command_whowas_send_reply,
2949 silc_server_command_whowas_from_client and
2950 silc_server_command_whowas_from_server
2952 * Added <Client ID> argument to the WHOWAS command reply. Updated
2953 the protocol specs accordingly.
2955 * Implemented WHOWAS command and command_reply to the client
2958 Implemented the WHOWAS printing on the user interface.
2960 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2962 * Added new argument to the WHOWAS command reply, the real name.
2963 It is an optional argument. Updated the protocol specs.
2965 * Added SilcIDCacheDestructor callback that is registered when
2966 the SilcIDCache is allocated. The callback is called when
2967 an cache entry in the ID Cache expires, or is purged from the
2968 cache. Added into lib/silccore/idcache.[ch].
2970 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2971 to destruct the client entries when the cache entry expires.
2972 Other ID Cache's in server and in the client library ignores
2975 * If the ID Cache entry's `expire' field is zero then the entry
2976 never expires. Added boolean `expire' argument to the
2977 silc_idcache_add function in the lib/silccore/idcache.[ch].
2978 If it is TRUE the default expiry value is used.
2980 * Added silc_server_free_client_data_timeout that is registered
2981 when client disconnects. By default for 5 minutes we preserve
2982 the client entry for history - for WHOWAS command.
2984 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Added support to the server to enforce that commands are not
2987 executed more than once in 2 seconds. If server receives
2988 commands from client more frequently, timeout is registered
2989 to process the commands. Affected file silcd/command.c.
2990 Added new function silc_server_command_process_timeout.
2992 * Changed NICK_NOTIFY handling in client library to check that
2993 if the client's nickname was changed, so there is no need to
2994 resolve anything from the server.
2996 * Removed error printing from the WHOIS and IDENTIFY commands.
2997 If error occurs then it is ignored silently in the client library.
2998 The application, however, may map the received error to
2999 human readable error string. The application currently maps
3000 the NO_SUCH_NICKNAME error to string.
3002 * Made the command status message public to the application. Moved
3003 them from lib/silcclient/command_reply.c to
3004 lib/silcclient/command_reply.h. The application can map the
3005 received command status to the string with the
3006 silc_client_command_status_message function.
3008 * Added check to the server to check that client's ID is same
3009 as the Source ID in the packet the client sent. They must
3012 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Added dist-bzip hook to the Makefile.am to make bzip2
3015 compressed distributions.
3017 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Server now enforces the maximum length for the nickname and
3020 the channel as protocol specification dictates. 128 bytes for
3021 nickname and 256 bytes for channel name.
3023 * Moved the WHOIS printing to the application. The client libary
3024 does not print out the WHOIS information anymore, the application
3025 must do it. Renamed silc_client_command_reply_whois_print to
3026 the silc_client_command_reply_whois_save.
3028 The client's idle time is also sent to the application now, and
3029 the idle is shown on screen.
3031 * Added silc_client_command_reply_identify_save to save the
3032 received IDENTIFY entries.
3034 * Do not check for channel private keys in message sending and
3035 reception if the channel does not have the PRIVKEY mode set.
3036 Affected file lib/silclient/client_channel.c.
3038 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3041 just surfaced after chaning the JOIN procedure.
3043 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Added silc_client_get_clients_by_list to get client entries
3046 from Client ID list, that is returned for example by JOIN
3047 and USERS command replies. The application should use this
3048 function for example when JOIN command reply is received to
3049 resolve the clients already on the channel (library does not
3050 do that anymore as USERS command reply is not used in the JOIN
3051 procedure anymore). Affected files lib/silcclient/silcapi.h and
3052 lib/silcclient/idlist.c.
3054 * JOIN command reply and USERS command reply returns now SilcBuffer
3055 pointers instead of unsigned char pointers when returning
3056 the client list and mode list.
3058 * Added <Client ID> argument to the JOIN command reply, mainly
3059 for the server to identify for which client the command was
3060 originally sent. Updated protocol specs accordingly.
3062 * Added SilcDlist private_key pointer to the SilcChannelEntry
3063 in the client to support the channel private keys. Affected
3064 file is lib/silcclient/idlist.h.
3066 * Added SilcChannelPrivateKey argument to the function
3067 silc_client_send_channel_message so that application can choose
3068 to use specific private ke if it wants to. If it is not provided,
3069 the normal channel key is used, unless private keys are set.
3070 In this case the first (key that was added first) is used
3071 as the encryption key.
3073 * Implemented the support for channel private key handling.
3074 Implemented the following functions:
3076 silc_client_add_channel_private_key,
3077 silc_client_del_channel_private_keys,
3078 silc_client_del_channel_private_key,
3079 silc_client_list_channel_private_keys and
3080 silc_client_free_channel_private_keys
3082 Affected file lib/silcclient/client_channel.c.
3084 * Added the support for the private keys in the channel message
3085 sending and encryption and in the message reception and
3086 decryption. Affected funtions are
3087 silc_client_send_channel_message and silc_client_channel_message.
3089 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Added SKE's key verify callback to the client library's
3092 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3094 * Removed the statement that server (or router) must send USERS
3095 command reply when joining to the channel so that the client
3096 knows who are on the channel. Instead, the client list and
3097 client's mode list is now sent in the JOIN command reply to the
3098 client who joined channel. This is better solution.
3100 * Added function silc_server_get_users_on_channel and function
3101 silc_server_save_users_on_channel to the silcd/server.[ch].
3103 * Removed function silc_server_command_send_users from the
3106 * Do not show topic on the client library anymore. The topic is
3107 sent in the command reply notify to the application and the
3108 application must show the topic now.
3110 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Added client searching by nickname hash into the IDENTIFY and
3113 WHOIS commands in the server as they were clearly missing from
3114 them. Affected file is silcd/command.c.
3116 * Fixed a bug in private message receiving in the client library.
3117 The remote ID was freed and it wasn't supposed, now it is
3120 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Minor fix to the channel payload; allocate the data area, as it
3123 needs to be of specific length.
3125 * If the key agreement port is zero then the operating
3126 system will define the bound port. Affected files are
3127 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3129 * Added new function silc_channel_payload_decrypt into the file
3130 lib/silccore/silcchannel.[ch].
3132 * Moved the channel message etc, check from silc_packet_decrypt
3133 to applications. The library calls now a generic
3134 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3135 when the packet is either normal or special. This was done to
3136 allow more wide range of checking that was not allowed when
3137 the code was in library. Now applications can do virtually any
3138 checks to the packet and return to the library the decision how
3139 the packet should be processed. Affected files are
3140 lib/silccore/silcpacket.[ch].
3142 Added silc_server_packet_decrypt_check to the server and
3143 silc_client_packet_decrypt_check to the client library.
3145 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3146 to send with specified source and destination information.
3148 * Channel message delivery between routers was broken after the
3149 channel key distribution was fixed earlier. The channel key
3150 was used be to distributed to other routers as well which is not
3151 allowed by the protocol. Now this is fixed and channel keys
3152 really are cell specific and the channel message delivery between
3153 routers comply with the protocol specification.
3155 * Fixed various commands in server to check also the global list
3156 for the channel entry and not just the local list. The affected
3157 file silcd/command.c.
3159 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added assert()s to buffer formatting and unformatting routines
3162 to assert (if --enable-debug) when error occurs. Affected
3163 file: lib/silcutil/silcbuffmt.c.
3165 * Changed to auto-reconnect to check whether the remote host is
3166 router and register the re-connect timeout if it is. It used
3167 to check that whether we are normal server, but router must do
3168 auto-reconnect with another router as well. Affected file
3171 * Removed the [<key len>] option from CMODE command as the cipher
3172 name decides the key length, nowadays. See the defined ciphers
3173 from the protocol specification.
3175 * Added [<hmac>] option to the CMODE command to define the HMAC
3176 for the channel. Added SILC_CMODE_HMAC channel mode.
3178 * Added [<hmac>] option for the JOIN command so that user can
3179 select which HMAC is used to compute the MACs of the channel
3182 * Added Hmac field to the Channel Message Payload. The integrity
3183 of plaintext channel messages are now protected by computing
3184 MAC of the message and attaching the MAC to the payload. The
3185 MAC is encrypted. Now, it is clear that this causes some
3186 overhead to the size of the packet but rationale for this is that
3187 now the receiver can verify whether the channel message decrypted
3188 correctly and also when private keys are set for the channel the
3189 receiver can decrypt the packet with several keys and check from
3190 the MAC which key decrypted the message correctly.
3192 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3193 lib/silccrypt/silccipher.[ch].
3195 * Added silc_hash_len to return the digest length into the
3196 lib/silcrypt/silchash.[ch].
3198 * Rewrote parts of Silc Channel Payload interface in the
3199 lib/silccore/silcchannel.[ch]. The encode function now also
3200 encrypts the packet and parse function decrypts it.
3202 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Fixed a minor formatting bug in the SKE's key material processing.
3205 It actually might have processed the keys wrong way resulting
3208 * Redefined the mandatory HMAC algorithms and added new algorithms.
3209 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3210 and hmac-md5 truncated to 96 bits. The mandatory is now
3211 hmac-sha1-96. Rest are optional (including the one that used
3212 to be mandatory). Rationale for this is that the truncated HMAC
3213 length is sufficient from security point of view and can actually
3214 make the attack against the HMAC harder. Also, the truncated
3215 HMAC causes less overhead to the packets. See the RFC2104 for
3218 * Added new [hmac] configuration section. The SKE used to use
3219 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3220 is of course wrong. The official names that must be proposed in
3221 the SKE are the ones defined in the protocol specification
3222 (hmac-sha1-96 for example). The user can configure any hmac
3223 using any hash function configured in the [hash] section. At
3224 least, the mandatory must be configured.
3226 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3228 * Added HMAC list to the SKE proposal list. It has now both
3229 hash algorithm list and HMAC list. This makes the protocol
3230 incompatible with previous versions. The SKE now seems to work
3231 the way it is supposed to work, for the first time actually.
3233 * Defined plain Hash algorithms to the protocol specification.
3236 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Implemented support for key agreement packets into the server.
3239 Added functions silc_server_key_agreement and
3240 silc_server_send_key_agreement. Other than these functions,
3241 server has nothing to do with this packet.
3243 * Added support for private message key packets into the server.
3244 Added functions silc_server_private_message_key and
3245 silc_server_send_private_message_key.
3249 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3250 called in the protocol's final callback instead in the END
3251 protocol state. This makes a little more sense and in the same
3252 time in client we can use the same protocol routines for normal
3253 key exchange and to key agreement packet handling as well.
3255 * Added to both client's and server's KE protocol context the
3256 SilcSKEKeyMaterial pointer to save the key material. We will
3257 bring the key material to the protocol's final callback by doing
3258 this. The final callback must free the key material.
3260 * Added SKE's packet_send callback into client's KE protocol
3261 context so that the caller can choose what packet sending function
3262 is used. This way we can use different packet sending when
3263 doing normal SKE when doing key agreement packet handling (in
3264 the key agreement packet handling we do not want to encrypt
3267 * Implemented the responder side of the key agreement routines
3268 in the client. The client can now bind to specified port and
3269 accept incoming key negotiation. The key material is passed
3270 to the application after the protocol is over.
3272 * Implemented the processing of incoming Key Agreement packet
3273 in the client. Added function silc_client_key_agreement to
3276 * Implemented the intiator side of the key agreement routines
3277 in the client. The client can now initiate key agreement with
3278 another remote client. The key material is passed to the
3279 application after the protocol is over.
3281 * Created client_keyagr.c to include all the key agreement
3284 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3285 SILC_TASK_CALLBACK except that it is not static.
3287 * Created client_notify.c and moved the Notify packet handling
3288 from the client.[ch] into that file.
3290 * Created client_prvmsg.c and moved all private message and
3291 private message key routines from the client.[ch] into that file.
3293 * Create client_channel.c and moved all channel message and
3294 channel private key routines from the client.[ch] into that file.
3296 * Changed silc_client_get_client_by_id_resolve to resolve with
3297 WHOIS command instead of IDENTIFY command, in the file
3298 lib/silclient/idlist.c.
3300 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Implemented the SKE's responder side to the Client library.
3304 * When FAILURE is received to the protocol do not trust it
3305 blindly. Register a timeout to wait whether the remote closes
3306 the connection as it should do it, only after that process the
3307 actual failure. This was changed to both client and server.
3309 * Added client_internal.h to include some of the structures
3310 there instead of client.h in lib/silcclient/.
3312 * Added function silc_task_unregister_by_callback to unregister
3313 timeouts by the callback function.
3315 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3317 * Some "Incomplete WHOIS info" errors has been appearing on the
3318 log files. Took away the entry->userinfo check from WHOIS
3319 reply sending. The entry->userinfo is now " " if client did not
3320 provide one. I thought this was fixed earlier but something
3321 is wrong still. Let's see if the error still appears.
3323 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Fixed a minor bug in the login when the channel key is
3326 re-generated in the server. It used to generate the key in
3327 wrong order and thus caused problems in the channel traffic.
3329 * Fixed a minor bug in channel key distsribution after
3330 KICK command. The key was not sent to the router even though
3333 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Added silc_ske_process_key_material_data as generic routine
3336 to process any key material as the SILC protocol dictates. The
3337 function is used by the actual SKE library but can be used by
3338 applications as well. This relates to the private message keys
3339 and the channel private keys since they must be processed the
3340 same way the normal SILC session keys. The protocol dictates
3341 this. Affected files: lib/silcske/silcske.[ch].
3343 Added also silc_ske_free_key_material to free the
3344 SilcSKEKeyMaterial structure.
3346 * Defined silc_cipher_set_key function to set the key for
3347 cipher without using the object's method function. The affected
3348 files: lib/silccrypt/silccipher.[ch].
3350 * Implemented silc silc_client_add_private_message_key,
3351 silc_client_add_private_message_key_ske,
3352 silc_client_del_private_message_key,
3353 silc_client_list_private_message_keys and
3354 silc_client_free_private_message_keys functions in the
3357 Added functions silc_client_send_private_message_key to send
3358 the Private Message Key payload and silc_client_private_message_key
3359 to handle incoming Private Message Key payload.
3361 * Added Cipher field to the Private Message Key payload to set
3362 the cipher to be used. If ignored, the default cipher defined
3363 in the SILC protocol (aes-256-cbc) is used.
3365 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Removed lib/silcclient/ops.h file.
3369 Redefined parts of the SILC Client Library API. Created new
3370 file silcapi.h that deprecates the ops.h file and defines the
3371 published Client Library API. Defined also private message key
3372 API and channel private key API into the file.
3374 This is the file that the application must include from the
3375 SILC Client Library. Other files need not be included by
3376 the application anymore.
3378 * Added new key_agreement client operation callback and also
3379 defined the Key Agreement library API for the application.
3381 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3384 is used by clients to request key negotiation between another
3385 client in the SILC network. If the negotiation is started it
3386 is performed using the SKE protocol. The result of the
3387 negotiation, the secret key material, can be used for example
3388 as private message key.
3390 Implemented the Key Agreement payload into the files
3391 lib/silccore/silauth.[ch].
3393 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Redefined ciphers for the SILC protocol. Added some new ciphers
3396 and defined the key lengths for the algorithms. Changed the
3397 code accordingly. The default key length is now 256 bits.
3399 * Fixed SKE key distribution function silc_ske_process_key_material
3400 when the key length is more than 128 bits. The default key
3401 length in SILC is now 256 bits.
3403 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3404 to indicate unsupported algorithm.
3406 * Renamed rijndael.c to aes.c and all functions as well.
3408 * Fixed a long standing channel key setting bug in client library.
3409 Weird that it has never surfaced before.
3411 * Fixed bug in channel deletion. If the entire channel is removed
3412 then it must also delete the references of the channel entry
3413 from the client's channel list as the client's channel entry and
3414 the channel's client entry share same memory.
3416 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Implemented CONNECT and SHUTDOWN commands in the client.
3420 * Implemented CLOSE command to the client.
3422 * Added the function silc_idlist_find_server_by_name into the
3423 files silcd/idlist.[ch].
3425 Added the function silc_idlist_find_server_by_conn into the
3426 files silcd/idlist.[ch].
3428 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * DIE command was renamed to SHUTDOWN. Updated the both code
3433 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3434 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3436 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3439 * Added function silc_server_create_connection function to create
3440 connection to remote router. My server implementation actually
3441 does not allow router to connect to normal server (it expects
3442 that normal server always initiates the connection to the router)
3443 so the CONNECT command is only good for connecting to another
3446 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3449 or some other client was kicked from the channel.
3451 Implemented the handling of the notify type to both client
3454 Implemented silc_server_send_notify_kicked to send the KICKED
3455 notify. It is used to send it to the server's primary router.
3457 * Implemented the KICK command into server and client.
3459 * Added `query' argument to the silc_idlist_get_client function
3460 to indicate whether to query the client from server or not if
3463 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3464 to indicate that the client is not channel founder.
3468 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Removed the rng context from SilcPacketContext structure and
3471 changed that the packet routine uses the Global RNG API.
3473 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Added support for quit message that client can "leave" on the
3476 channel when it quits the SILC. It is ditributed inside the
3477 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3479 Added silc_server_free_client_data that will take the
3480 signoff message as argument.
3482 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3484 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Updated parts of the protocol specification to keep it up
3489 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3492 payloads in one packet.
3494 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3495 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3496 use now the new List flag.
3498 * Also deprecated the following packet types: REPLACE_ID,
3499 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3501 * Added list support for Notify packet in server.
3503 * Added silc_server_send_notify_channel_change to send the
3504 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3505 the silc_server_send_replace_id.
3507 * Added silc_server_send_notify_nick_change to send the
3508 NICK_CHANGE notify type. Deprecates the function
3509 silc_server_send_replace_id.
3511 * Added silc_server_send_notify_join to send the JOIN notify type.
3512 Deprecates the function silc_server_send_new_channel_user.
3514 * Added silc_server_send_notify_leave to send LEAVE notify type.
3515 Deprecates the function silc_server_send_remove_channel_user.
3517 * Added silc_server_send_notify_cmode and
3518 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3519 types. Deprecates the silc_server_send_set_mode function.
3521 * Added SERVER_SIGNOFF notify type to indicate that server has
3522 quit. This means that all clients on the channel from that
3523 server will drop. This can be also used when netsplit happens.
3525 Deprecated REMOVE_ID packet type since it is not needed anymore
3528 Added silc_server_send_notify_server_signoff to send the
3529 SERVER_SIGNOFF notify type. Deprecates the function
3530 silc_server_send_remove_id.
3532 Added also silc_server_send_notify_signoff to send the
3533 SIGNOFF notify type.
3535 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3536 SILC protocol from this day on. Changed the protocol
3537 specification as well.
3539 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3540 notify type. It is used between routers to notify about
3541 topic changes on a channel.
3543 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3546 * Partly updated the protocol specification to comply with the
3547 changes now made. It is still though a bit outdated.
3549 * The JOIN notify type now takes one extra argument <Channel ID>.
3550 The packet used to be destined to the channel but now the
3551 JOIN type may be sent as list thus it is impossible to
3552 destine it to any specific channel. By adding this argument
3553 it is again possible.
3555 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Added CREDITS file. The CHANGES and CREDITS file will appear
3558 in the distribution as well.
3560 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3563 types in the server's silcd/packet_receive.c.
3565 * Implemented CMODE and CUMODE to work in router environment.
3567 * Fixed minor encoding and decoding buglet from the
3568 lib/silccore/silcmode.c.
3570 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3573 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3575 * Changed all SilcConfigServer* and silc_config_server* to
3576 SilcServerConfig* and silc_server_config*, respectively.
3579 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Associated the ID (client or server ID) to the Authentication
3582 Payload to avoid any possibility of forging. Updated the
3583 protocol specification and the code accordingly.
3585 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * The RSA key length is now save to the RsaKey context in the
3588 key generation process in lib/silccrypt/rsa.c. The key length
3589 is now used to figure out the maximum size of the block allowed
3590 to be encrypted/signed.
3592 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3593 is equivalent to the silc_mp_mp2bin but does not allocate any
3596 * Changed silc_mp_mp2bin API to take length argument. If it is
3597 non-zero then the buffer is allocated that large. If zero, then
3598 the size is approximated using silc_mp_sizeinbase, which however
3601 * Created Global RNG API which is global RNG that application can
3602 initialize. After initializing, any routine anywhere in the
3603 code (including library) can use RNG without allocating a new
3604 RNG object. This was done to allow this sort of use of the
3605 RNG in code that has no chance to allocate RNG object. All
3606 applications currently allocate this and many routines in the
3607 library use this. Affected file lib/silccrypt/silcrng.[ch].
3609 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3610 it to use the Global RNG API.
3612 * Defined Authentication Payload into protocol specification that
3613 is used during SILC session to authenticate entities. It is
3614 used for example by client to authenticate itself to the server
3615 to obtain server operator privileges.
3617 Implemented this payload into the lib/silccore/silcauth.[ch].
3618 Implemented also routines for public key based authentication
3619 as the new protocol specification dictates.
3621 Moved definitions of different authentication methods from
3622 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3624 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3625 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3626 silc_pkcs_verify_with_hash functions into the file
3627 lib/silccrypt/silcpkcs.[ch].
3629 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * The client entry's userinfo pointer must be always valid.
3632 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3633 will fail since it requires the userinfo. Now, the userinfo
3634 is allocated as "" if actual userinfo does not exist. Actually,
3635 it must exist and it is totally Ok to drop client connections
3636 that does not announce the userinfo. However, we will make
3637 this workaround for now.
3639 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3640 to return the remote port by socket.
3642 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3645 SILC_SERVER_PENDING_EXEC and added an new macro
3646 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3647 data or when error occurs while processing the pending command.
3649 Added new argument `destructor' into silc_server_command_pending
3650 and to the SilcServerCommandPending object. This destructor is
3651 now called after calling the pending callback or if error occurs
3652 immediately. If error occurs the actual pending callback won't
3653 be called at all - only the destructor. The destructor may be
3654 NULL if destructor is not needed.
3656 All this applies for client library code as well. Similar
3657 changes were made there as well for the pending commands.
3659 In the client, the application must now allocate the
3660 SilcClientCommandContext with the silc_client_command_alloc
3663 * Added reference counter to the SilcServerCommandContext. Added
3664 function silc_server_command_alloc and silc_server_command_dup
3667 Same type of functions added to the client library for the same
3670 * Removed the cmd_ident from IDListData away since it is now
3671 global for all connections. It is the command identifier used
3672 in command sending and with pending commands. The affected file
3675 * Added reference counter to the SilcSocketConnection objecet to
3676 indicate the usage count of the object. The object won't be
3677 freed untill the reference counter hits zero. Currently only
3678 server uses this, and client ignores it. The client must be
3679 set to use this too later. The affected files are
3680 lib/silccore/silcsockconn.[ch]. Added also the function
3681 silc_socket_dup to increase the reference counter.
3683 This was mainly added because it is possible that the socket
3684 is removed underneath of pending command or other async
3685 operation. Now it won't be free'd and proper DISCONNECTING
3686 flags, etc. can be set to avoid sending data to connection that
3687 is not valid anymore.
3689 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3690 the connection. After that it sets SILC_SET_DISCONNECTED.
3691 It is, however, possible that the socket data is not still freed.
3692 The silc_server_packet_process now checks that data is not
3693 read or written to connection that is DISCONNECTED. The socket
3694 get's freed when the reference counter hits zero.
3696 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Changed the client operation API: channel_message operation's
3699 `sender' is now the client entry of the sender, not the nickname
3700 and the `channel' is the channel entry, not the channel name.
3702 In the private_message operation the `sender' is now also the
3703 client entry of the sender not the nickname.
3705 Affected file is lib/silcclient/ops.h and all applications
3706 using the client operations.
3708 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Moved the calling of ops->connect() from connect_to_server_final
3711 into receive_new_id functin since that is the point when the
3712 client is actually allowed to send traffic to network. The
3713 affected file is lib/silcclient/client.c.
3715 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3718 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3719 (if needs broadcasting) instead of broadcasting the packets one
3720 by one which would make a burst in the network traffic.
3722 * Added `broadcast' argument to the functions in silcd/server.[ch]
3723 silc_server_create_new_channel[_with_id] to indicate whether
3724 to send New Channel packet to primary router.
3726 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Added new function into the silcd/server.[ch] files:
3729 silc_server_create_new_channel_with_id to create new channel with
3730 already existing Channel ID.
3732 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3733 lib/silccore/silcpacket.h. This packet is used t send list of
3734 Set Mode payloads inside one packet. Server uses this to set
3735 the modes for the channels and clients on those channels, that it
3736 announced to the router when it connected to it. The protocol
3737 specification has been updated accordingly.
3739 * The silc_server_new_channel did not handle the packet coming
3740 from normal server as it normally does not send that. However,
3741 when it announces its channels it does send it. Implemented
3742 the support for that.
3744 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3745 into the file lib/silccore/id.h.
3747 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Fixed memory leaks in the functions silc_idlist_del_client,
3750 silc_idlist_del_channel and silc_idlist_del_server in the file
3751 silcd/idlist.c. All of those leaked like a sieve.
3753 * Fixed some small memory leaks in the client's function
3754 silc_client_notify_by_server.
3756 * Added functions into silcd/server.c: silc_server_announce_clients,
3757 silc_server_announce_channels and silc_server_announce_server.
3758 These functions are used by normal and router server to announce
3759 to its primary router about clients, channels and servers (when
3760 router) that we own. This is done after we've connected to the
3763 These functions effectively implements the following packet types:
3764 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3765 and SILC_PACKET_NEW_ID_LIST.
3767 * Added new functions into the silcd/packet_receive.[ch]:
3768 silc_server_new_id_list, silc_server_new_channel_list and
3769 silc_server_new_channel_user_list to handle the incoming
3770 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3772 * Added support of changing Channel ID in the function
3773 silc_server_replace_id. If the server that announces a channel
3774 to the router already exists in the router (with same name but
3775 with different Channel ID), router is responsible to send
3776 Replace ID packet to the server and force the server to change
3777 the Channel ID to the one router has.
3779 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3780 client that the Channel ID has been changed by the router. The
3781 normal server sends this to the client. Client must start using
3782 the new Channel ID as the channel's ID.
3784 Implemented handling of this new type into lib/silcclient/client.c
3785 into the function silc_client_notify_by_server.
3787 * Added new function silc_idlist_replace_channel_id into the files
3788 silcd/idlist.[ch] to replace the Channel ID.
3790 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Call silc_server_command_identify_check always when processing
3793 the IDENTIFY command in silcd/command.c
3795 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3798 send keepalive packets. The packet can be sent by clients,
3799 servers and routers.
3801 Added function silc_socket_set_heartbeat into the file
3802 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3803 If not set, the heartbeat is not performed. The actual
3804 heartbeat is implemented in the low level socket connection
3805 library. However, application is responsible of actually
3808 Added silc_server_send_heartbeat to send the actual heartbeat
3809 packet into silcd/packet_send.[ch]. Server now performs
3810 keepalive with all connections.
3812 * Added silc_task_get_first function into lib/silcutil/silctask.c
3813 to return the timeout task with shortest timeout. There was a bug
3814 in task unregistration that caused problems. TODO has been
3815 updated to include that task system must be rewritten.
3817 * The client library will now resolve the client information when
3818 receiving JOIN notify from server for client that we know but
3819 have incomplete information.
3821 * Rewrote parts of silc_server_remove_from_channels and
3822 silc_server_remove_from_one_channel as they did not remove the
3823 channel in some circumstances even though they should've.
3825 * Encryption problem encountered in server:
3827 The LEAVE command used to send the Channel Key packet to the
3828 router immediately after generating it. However, the code
3829 had earlier sent Remove Channel user packet but not immediately,
3830 ie. it was put to queue. The order of packets in the router
3831 was that Channel Key packet was first and Remove Channel User
3832 packet was second, even though they were encrypted in the
3833 reverse order. For this reason, MAC check failed. Now, this
3834 is fixed by not sending the Channel Key packet immediately but
3835 putting it to queue. However, this is more fundamental problem:
3836 packets that are in queue should actually not be encrypted
3837 because packets that are sent immediately gets encrypted
3838 actually with wrong IV (and thus MAC check fails). So, packets
3839 that are in queue should be encrypted when they are sent to
3840 the wire and not when they put to the queue.
3842 However, the problem is that the current system has not been
3843 designed to work that way. Instead, the packet is encrypted
3844 as soon as possible and left to the queue. The queue is then
3845 just purged into wire. There won't be any fixes for this
3846 any time soon. So, the current semantic for packet sending
3849 o If you send packet to remote host and do not force the send
3850 (the packet will be in queue) then all subsequent packets to the
3851 same remote host must also be put to the queue. Only after the
3852 queue has been purged is it safe again to force the packet
3855 o If you send all packets immediately then it safe to send
3856 any of subsequent packets through the queue, however, after
3857 the first packet is put to queue then any subsequent packets
3858 must also be put to the queue.
3860 Follow these rules and everything works fine.
3862 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added new function silc_server_remove_clients_by_server to
3865 remove all client entries from ID list when the server connection
3866 is lost. In this case it is also important to invalidate all
3867 client entires as they hold the invalid server entry. This
3868 fixes fatal bug when server has lost connection and will reconnect
3871 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Made some sanity checks to silc_server_daemonise like to check
3874 whether the requested user and group actually exists.
3876 * Added sanity check to SKE's silc_ske_responder_finish to check
3877 that the public and private key actually is valid.
3879 * Invalidate the client's nickname when receiving Replace ID
3880 packet and the Client ID is being replaced. This means that the
3881 server will query the nickname if someone needs it (client)
3884 * Sort the ID Cache in client library when the ID Cache data
3885 has changed (needs sorting).
3887 * Do not allow for SILC client to create several connections to
3888 several servers. The client does not support windows right now
3889 and generating multiple connections causes weird behaviour.
3891 Irssi-silc client does support windows and can handle several
3892 connections without problems, see: www.irssi.org and SILC plugin.
3894 * Fixed some places where client was added to the IDList. The
3895 rule of thumb is following (in order to get everything right):
3896 If the client is directly connected local client then the
3897 `connection' argument must be set and `router' argument must be
3898 NULL to silc_idlist_add_client function. If the client is not
3899 directly connected client then the `router' argument must
3900 bet set and the `connection' argument must be NULL to the
3901 silc_idlist_add_client function.
3903 * The funtion silc_server_packet_send_local_channel actually did
3904 not check whether the client was locally connected or not. It
3905 does that now. Fixed a bug related to LEAVE command.
3907 * Fixed Remove Channel User payload parsing bug in server's
3908 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3910 * The server's silc_server_save_channel_key now checks also the
3911 global ID list for the channel as it might not be in the local
3912 list. Fixed a bug related to LEAVE command.
3914 * Is this the end of the [<unknown>] buglet that has been lurking
3915 around for a long time? A little for loop fix in server's
3916 silc_server_command_whois_parse that is used by both IDENTIFY
3917 and WHOIS command. At least, this was a clear bug and a cause
3918 of one type of [<unknown>] buglet.
3920 * WHOIS and IDENTIFY commands call the function
3921 silc_server_command_[whois/identify]_check function even if
3922 we are not router server.
3924 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Added --with-gmp configuration option. If set the GMP
3927 is always compiled in the SILC source tree. If not set then
3928 it is checked whether the system has the GMP3 installed. If
3929 it has then the GMP won't be compiled (the system's headers
3930 and library is used), if it doesn't have it then the GMP is
3931 compiled in the SILC source tree.
3933 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Changed RSA private exponent generation to what PKCS #1
3936 suggests. We try to find the smallest possible d by doing
3937 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3938 not security fix but optimization.
3940 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Added new config entry [Identity] to fork the server and run
3943 it as specific user and group. A patch from Bostik.
3945 * Imported Dotconf configuration library into lib/dotconf.
3946 This will be used to create the SILC configuration files later.
3947 It will appear in the distsribution after this commit.
3949 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * A big code auditing weekend happening. Auditing code for
3952 obvious mistakes, bugs and errors. Also, removing any code
3955 Removed files for being obsolete:
3957 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3958 inline in the file lib/silcutil/silcbuffer.h)
3960 o lib/silcutil/silcbufutil.c (the header has inline versions)
3962 Changed code to fix possible error conditions:
3964 o The buffer formatting routines now check that the destination
3965 buffer really has enough space to add the data. This applies for
3966 both buffer formatting and unformatting
3967 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3968 unformatting was changed to accomodate following rules:
3969 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3970 sent to the function while XXX_*STRING will not allocate or copy
3971 the data into the buffer. Instead it sets the pointer from the
3972 buffer into the pointer sent as argument (XXX_*STRING used to
3973 require that the pointer must be allocated already). This change
3974 makes this whole thing a bit more consistent and more optimized
3975 (note that the data returned in the unformatting with XXX_*STRING
3976 must not be freed now). The routines return now -1 on error.
3978 o Tried to find all code that use buffer_format and buffer_unformat
3979 and added return value checking to prevent formatting and
3980 especially unformatting errors and possible subsequent fatal
3983 o Changed ske->x and ske->KEY to mallocated pointers in
3984 lib/silcske/silcske.h. Fixed possible data and memory leak.
3986 o Added return value checking to all *_parse* functions. Fixed
3987 many memory leaks as well.
3989 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3990 so that buffer overflows would not happen. All code now also
3991 checks the return value as it can fail.
3993 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Added reconnection support to server if the normal server looses
3996 its connection to the router (for example if router is rebooted).
3997 The server performs normal reconnection strategy implemented
3998 to the server. Affected file silcd/server.c.
4000 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Added new packet type SILC_PACKET_SET_MODE that is used to
4003 distribute the information about changed modes (for clients,
4004 channels and clients channel modes) to all routers in the
4005 network. Updated the protocol specification accordingly.
4007 Added functions into silcd/packet_send.c and
4008 silcd/packet_receive.c: silc_server_send_set_mode,
4009 silc_server_set_mode.
4011 Added new files silcmode.[ch] into lib/silccore that implements
4012 the encoding and decoding of Set Mode Payload. Added new type
4013 SilcSetModePayload. Moved the definitions of different modes
4014 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4016 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Oops, a little mistake in server's connection authentication
4019 protocol. The protocol is not ended with FAILURE but with
4020 SUCCESS if the authentication is Ok. :) Affected file is
4023 * Implemented NICK_CHANGE notify handling in server in the file
4024 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4025 the local clients on the channel. After the changing nickname
4026 in router environment snhould work and the [<unknown>] nickname
4027 should appear no more.
4029 The silc_server_replace_id function that receives the Replace ID
4030 payload now sends the NICK_CHANGE notify type also in the file
4031 silcd/packet_receive.c
4033 * Changed WHOIS and IDENTIFY command to support the maximum amount
4034 of arguments defined in protocol specs (3328 arguments). This
4035 fixed a bug that caused problems when there were more than three
4038 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Added extra parameter, command identifier, to the
4041 silc_client_send_command so that explicit command identifier
4044 Changed that ID list routines uses specific command identifier
4045 when sending WHOIS/IDENTIFY requests to the server so that they
4046 can be identified when the reply comes back.
4048 Affected files lib/silcclient/command.[ch],
4049 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4051 * Added `sender' argument to silc_server_packet_send_to_channel
4052 to indicaet the sender who originally sent the packet to us
4053 that we are now re-sending. Ignored if NULL. Affected file
4054 silcd/packet_send.[ch].
4056 * Added some server statistics support in silcd/server_internal.h
4057 SilcServerStatistics structure and around the server code. Also
4058 send some nice statistics information when client is connecting
4061 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Fixed channel ID decoding in server's JOIN command reply in
4064 silcd/command_reply.c
4066 * Fixed braodcasting of replace ID payload to not to send it if
4067 we are standalone server in silcd/packet_receive.c.
4069 * Fixed all channel message sending routines to not to send
4070 packets to clients that has router set, since they are routed
4071 separately in the same function earlier. Affects file
4072 silcd/packet_send.c and all channel packet sending functions.
4074 * In USERS reply, res_argv[i] are not allocated, the table
4075 is allocated. Thus changed that free the table, not its
4078 * In server's whois_check and identify_check if the client is
4079 locally connected do not send any WHOIS commands - they are not
4082 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Fixed some minor bugs in client when sending WHOIS command. The
4085 arguments was in wrong order.
4087 * Removed statis function add_to_channel from server in
4088 silcd/command.c that was previously used with the joining but
4091 * Tested USERS command in router environment successfully with two
4092 routers, two servers and two clients.
4094 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Reorganized the USERS command and command reply in client library
4097 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4098 When the command is given by user we register a pending command
4099 callback that will reprocess the command after the reply has been
4100 received from the server. When reprocessing the packet we then
4101 display the information. Thus, the USERS information is displayed
4102 now in the command callback instead of in the command reply
4103 callback. The processing of the command is same as previously
4104 when server has sent the command reply in the JOINing process.
4106 * Added to USERS command in silcd/command_reply.c to join the client,
4107 we didn't use to know about, to the channel after we've created
4108 a client entry for it. Also, for clienet we did know already still
4109 check whether it is on the channel or not and add it if not.
4111 * Removed silc_server_command_join_notify as the function and its
4114 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Changed the client's pending command handling to the same as the
4117 server's pending command handling. It is also now possible to
4118 execute command reply functions from other command reply
4119 function as the function callbacks for commands and command
4120 replies are one and same. The pending commands are not static
4121 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4122 in client connection context. Thus, pending commands are server
4123 connection specific as it is convenient.
4125 Changed the function silc_client_command_pending and
4126 silc_client_command_pending_del and added new function
4127 silc_client_command_pending_check. Removed the
4128 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4131 * Added cmd_ident, current command identifier, to the client
4132 connection context in lib/silcclient/client.h to keep track on
4133 command identifiers used in command sending. Client's command reply
4134 function handling now supports the mandatory command identifiers.
4136 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4137 funtions in client to fully support pending command callbacks.
4139 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4140 as one of the arguments to the application in the command reply
4143 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4144 before first releasing SILC but came back. Now it is removed again
4145 and should come back nomore. The FORWARDED flag was used only
4146 by the JOINing procedure by forwarding the command packet to router.
4147 Now, the JOINing procedure has been changed to more generic (due
4148 to various router environment issues) and FORWARDED is not needed
4149 anymore for anything. The protocol specification is yet to be
4152 Now, removed silc_server_packet_forward from server and the flag
4153 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4155 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Renamed NAMES command to USERS command. The NAMES was named that
4158 due to historical reasons. Now it is renamed. Also, rewrote
4159 parts of the USERS command. The nickname list is not sent anymore
4160 by the server. Only Client ID and mode lists are sent in the USERS
4161 command. Changed this also to the protocol specification.
4163 The client now resolves the names and stuff after it receives
4164 the USERS list from the server when joining to the channel.
4166 * WHOIS and IDENTIFY commands has been changed to support multiple
4167 Client ID's per command. One can now search for multiple users
4168 in the network by sending only one WHOIS or IDENTIFY command.
4169 Changed the code and the protocol specifications.
4171 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4172 uses silc_server_command_whois_parse to parse the request. */
4174 * If normal server, do not parse the WHOIS and IDENTIFY requests
4175 before sending it to the router. Saves some time.
4177 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Fixed JOIN command on client library. Wrong number of arguments
4180 used to crash the client.
4182 * Added silc_server_channel_has_global function to check whether
4183 channel has global users or not.
4185 * Added silc_server_channel_has_local function to check whether channel
4186 has locally connected clients on the channel.
4188 * The silc_server_remove_from_one_channel now checks whether the
4189 channel has global users or not after given client was removed from
4190 the channel. It also checks whether the channel has local clients
4191 on the channel anymore. If it does not have then the channel entry
4192 is removed as it is not needed anymore.
4194 * The silc_server_notify now checks on JOIN notify whether the joining
4195 client is one of locally connected or global. If it is global then
4196 the channel has now global users on the channel and that is marked
4197 to the channel entry. Also, it now saves the global client to
4198 global list who is joining and JOINs it to the channel. This is
4199 for normal server, that is.
4201 Changed silc_server_send_notify_on_channel,
4202 silc_server_packet_relay_to_channel and
4203 silc_server_packet_send_to_channel check if we are normal server
4204 and client has router set (ie. global client) do not send the
4205 message to that client, as it is already routed to our router.
4207 * Implemented LEAVE notify type handling in silc_server_notify
4210 * Tested LEAVE command in router environment successfully. Tested
4211 with two routers, two servers and two clients.
4215 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4217 * Implemented SIGNOFF notify type handling in silc_server_notify
4220 * silc_server_remove_id now removes the client entry from all channels
4221 it has joined and thusly sends SIGNOFF notify type.
4223 * Rewrote the NAMES list generation in server by removing two excess
4224 loops. The lists are created now inside one loop.
4226 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * silc_server_remove_channel_user checks now also global list
4229 for channel and client.
4231 * silc_server_new_channel_user checks now both local and global
4232 list for channel and client. Fixed a bug in client id decoding.
4233 Used to decode wrong buffer.
4235 * silc_server_channel_message checks now both local and global
4236 list for channel entry.
4238 * Tested channel joining (hence JOIN) in router environment
4239 successfully. Tested with two routers, two servers and two
4242 * Tested channel message sending in router environment successfully.
4244 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Added silc_server_save_channel_key into server.[ch] to save the
4247 received channel key in Channel Key payload processing. It is
4248 also used in JOIN command reply handling.
4250 Equivalent function silc_client_save_channel_key added into
4251 client.[ch] into client library.
4253 * Changed JOIN command reply to send information whether the channel
4254 was created or not (is existing already) and the channel key
4255 payload. Changed protocol specs accordingly.
4257 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4258 the request was sent by ID and not by nickname. Crashed on
4261 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4264 now correctly save the received data.
4266 * silc_server_free_sock_user_data now notifies routers in the
4267 network about entities leaving the network.
4269 At the same time implemented functions silc_server_remove_id
4270 and silc_server_send_remove_id to receive and send REMOVE_ID
4271 packets. The packet is used to notify routers in the network
4272 about leaving entities. The ID removed will become invalid in
4275 * Added function silc_idlist_del_server into server. Removes and
4276 free's server entry from ID list.
4278 * silc_server_private_message function now checks, if we are router,
4279 that the destination ID really is valid ID, naturally.
4281 * In router when NEW_ID packet is received (for new client) the
4282 hash of the Client ID is saved in the ID Cache but the
4283 client->nickname is set to NULL, instead of putting the hash
4286 IDENTIFY command now also checks that client->nickname must be
4287 valid. If it is not if will request the data from the server who
4288 owns the client. Added new function
4289 silc_server_command_identify_check.
4291 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4292 to set the command to already allocated Command Payload.
4294 * Tested private message sending in router environment with two
4295 routers, two servers and two clients. Fixed minor bugs and now
4298 * Fixed segfault from client's NAMES command. Used to crash if
4301 * Forwarded packets must not be routed even if it is not destined
4302 to the receiver. Changed server code comply with this.
4304 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Added `require_reverse_mapping' boolean value to ServerParams
4307 structure. If TRUE (not default) the server will require that
4308 the connecting host has fully qualified domain name.
4310 If the reverse mapping is not required and hostname could not be
4311 found the IP address is used as hostname.
4313 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Implemented version string checking to both client and server.
4316 The check is incomplete currently due to the abnormal version
4317 strings used in development version of SILC.
4319 * Changed all command functions in server to use the new
4322 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Changed char *data to unsigned char *data in ID Cache system to
4325 support binary data as ID Cache data. Changed code to support
4326 binary data in lib/silccore/idcache.c.
4328 * Renamed silc_server_packet_relay_command_reply to
4329 silc_server_command_reply as it is normal packet receiving
4330 function. Rewrote the function to accept command replys for
4331 servers and not only for clients.
4333 * Mark remote router always as registered server if we are connecting
4334 to it. Otherwise, commands sent by the router to us are ignored.
4336 * All ID List find routines now returns the ID Cache Entry pointer
4337 as well if requested.
4339 * WHOIS command works now in router environment, tested with two
4340 routers, two servers and two clients.
4342 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4343 in router environment (as it is almost equivalent to WHOIS) but
4344 hasn't been tested thoroughly. Added new functions:
4346 silc_server_command_identify_parse
4347 silc_server_command_identify_send_reply
4348 silc_server_command_identify_from_client
4349 silc_server_command_identify_from_server
4351 * Disabled route cache adding because adding two different ID's with
4352 same IP replaces the old cache entry thus giving wrong route.
4353 The entry->router->connection is always the fastest route anyway
4354 so route cache may not be needed. Of course, new routes maybe
4355 established after receiving the ID when the entry->router->connection
4356 might not be anymore the most optimal.
4358 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Add route cache for received ID for fast routing.
4362 * Added silc_server_packet_route to route received packet on router
4363 that is not destined to us.
4365 * Renamed silc_server_get_route to silc_server_route_get.
4367 * Added id_string and id_string_len fields into SilcServer to
4368 include encoded ServerID for fast comparing without excess
4369 encoding of the ID's.
4371 * Cleaned up WHOIS command on server side. Added following static
4374 silc_server_command_whois_parse
4375 silc_server_command_whois_check
4376 silc_server_command_whois_send_reply
4377 silc_server_command_whois_from_client
4378 silc_server_command_whois_from_server
4380 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4381 arguments in command replies. All command functions should be
4382 updated to use this macro.
4384 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Minor typo fixes on command reply handling on server.
4388 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added silc_server_command_add_to_channel internal routine to add
4391 the client to the channel after router has created the channel and
4392 sent command reply to the server.
4394 * Added generic silc_server_send_command to send any command from
4397 * Use static buffer with ID rendering instead of duplicating data.
4399 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Fixed a channel user mode bug when joining to a channel server gave
4402 everybody channel founder rights, oops.
4404 * We mark ourselves as the router of the incoming server connection
4405 if we are router ourselves. This way we can check in some packet
4406 sending functions whether it is locally connected server. For
4407 incoming router connections we put NULL.
4409 * For router sending packets locally means now always sending the
4410 packet cell wide; to local clients and local servers. For normal
4411 server sending packet locally means sending it to only local
4414 * Fixed the JOIN command to really work in router environment. If the
4415 channel is created it is always created by the router. Router is
4416 also responsible of making the initial joining to the channel,
4417 sending JOIN notify to the sending server and distributing
4418 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4419 does not exist server doesn't do anything else but forward the
4420 command to the router which performs everything.
4422 * Added silc_server_send_channel_key function to send the Channel Key
4425 * Added silc_server_create_channel_key to create new channel key. The
4426 channel key is now re-generated everytime someone joins or leaves
4427 a channel, as protocol dictates. Note: channel->key_len is the
4430 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4433 packet_receive.[ch] to separate packet sending and receiving
4434 routines. The server.[ch] now includes everything else including
4435 actual packet processing (writing and reading data) and other
4438 Renamed silc_server_private_message_send_internal to
4439 silc_server_send_private_message. The routine is still though
4440 used only to relay private messages as server does not send
4441 private messages itself.
4443 Renamed silc_server_new_channel to silc_server_create_new_channel
4444 and added new function sicl_server_new_channel that handles the
4445 incoming New Channel packet. Added also new sending function
4446 silc_server_send_new_channel to send New Channel Payload.
4448 * Added new function silc_server_notify to process incoming notify
4449 packet to the server/router. Server may then relay the notify
4450 to clients if needed.
4452 * Added new function silc_server_new_channel_user to process incoming
4453 New Channel User packet. Router will redistribute the packet and
4454 send JOIN notify to its local clients and locally connected servers
4455 if needed. Normal server will send JOIN notify to its local client
4456 on same channel when received this packet. Added also corresponding
4457 sending function silc_server_send_new_channel_user to sent the
4460 * Added boolean route argument to send_notif_to_channel and
4461 packet_send_to_channel functions to attempt to route the packet
4462 if it is TRUE and send only locally if it is FALSE.
4464 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * silc_server_replace_id now broadcasts the received replace ID
4467 packet if it is not broadcast packet already. The router must
4468 broadcast to inform other routers about changed ID.
4470 * Added backpointer to server's router into SilcServer context in
4471 silcd/server_internal.h.
4473 * Fixed silc_server_packet_broadcast to send correct broadcast
4476 * The channel key is now distributed to the local client as soon
4477 as it is received from the router (in router environment) so that
4478 no other packet may be sent for the channel until client has
4481 * silc_server_remove_channel_user now broadcasts the received
4482 Remove Channel User packet if it is not broadcast packet already.
4483 The router must broadcast to inform other routers about removed
4486 * Added users field into SilcPacketContext that is a reference count
4487 of the context. One can increase the reference count by calling
4488 silc_packet_context_dup which is now changed to just increase the
4489 reference count instead of duplicating the data. The reference
4490 count is decresed by calling silc_packet_context_free that will
4491 free the data after the reference count hits zero.
4493 For now on the packet context and everything allocated into it
4494 (including the raw packet from network) must be freed by calling
4495 the new silc_packet_context_free function. Added also new function
4496 silc_packet_context_alloc that must be used now to allocate the
4497 context. This also means that if a routine is asynchronous from
4498 silc_[client/server]_packet_parse_type the packet context must
4499 be duplicated by calling silc_packet_context_dup. Otherwise it
4500 gets free'd after silc_[client/server]_packet_parse_type returns.
4501 Also, one must remember that if packet is duplicated then its
4502 reference count must be decresed by calling the free function as
4503 many times as it was duplicated.
4505 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4506 from both client and server.
4508 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Made joining to a channel working in router environment.
4512 * Cleaned up JOIN command on server side and create function
4513 silc_server_command_join_channel internal routine to make the
4516 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Changed silc_command_pending list to SilcDList. Also, added
4519 `ident' field to SilcServerCommandPending structure to identify
4520 the reply and to call correct callback.
4522 Added silc_server_command_pending_check function to replace the
4523 corresnponding macro. The silc_command_pending list is not
4526 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4527 to set identifier to previously allocated Command Payload. It
4528 is used to set identifier for command when resending Command
4531 * Added silc_command_payload_encode_payload to encode Command
4532 Payload buffer from SilcCommandPayload structure.
4534 * Added silc_argument_payload_encode_payload to encode Argument
4535 payload buffer from SilcArgumentPayload structure.
4537 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Changed WHOIS command to support router connection on server side.
4540 The whois request is always sent to router unless the server is
4541 standalone server. After server has received the reply from the
4542 router will it send the reply to the client.
4544 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4545 broadcast received broadcast packet. The function is used only
4546 by router. The broadcast packet is always sent to the router's
4549 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4550 render given ID to printable string, for log files for example.
4552 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Made basic router to router connections working. At least they
4555 can now connect to each other but nothing really works the way
4556 they are supposed - yet.
4558 * Added new initiator token to RouterConnection configuration
4559 file in silcd/serverconfig.[ch]. It is used to tell whether we
4560 are the initiator to the remote router or whether we'll expect
4561 the other end to connect.
4563 * Moved registering of listener task to silc_server_init, hence
4564 the server starts listenning as soon as it is run, even if it
4565 does not have connections to other routers. Let's see how well
4568 * Changed default connection retry timeouts for more suitable in
4571 * Removed cipher and such arguments from silc_idlist_add_client
4572 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4573 Added new function silc_idlist_add_data to add the keys and stuff
4576 * Added SilcIDListData structure and added it to SilcClientEntry
4577 and SilcServerEntry as their first field in the structure. This
4578 way we can explicitly cast the ID entries to the SilcIDListData
4579 structure and get common data for the entries. In past, we had
4580 to first check what type of connection it is and then cast it to
4581 correct ID entry type. Now, we can directly cast the opaque
4582 pointer to the SilcIDListData (no matter what ID entry it actually
4583 is) and get the data needed.
4585 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4588 in some circumstances even if threre were timeout tasks, though not
4589 IO tasks, but tasks anyway. Now fixed.
4591 * Defined SilcServerConnection structure to hold connection specific
4592 stuff about directly connected servers and routers. The definition
4593 is currently in silcd/server_internal.h. I thought about having
4594 a bit more important role fro this struct but for now it is used
4595 only when connecting to other server (or router actually).
4597 * Added connecting retry support in server when connecting to
4598 router(s). The retry feature implement exponential backoff
4599 algorithm. Also, added SilcServerParams structure to hold default
4600 parameters for server. For now, it include these retry settings
4601 and are hard coded. After server is moded to be as Silc Server
4602 Library this structure will be more important.
4604 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Changed client librarys channel->clients table to SilcList and
4607 changed code accordingly.
4609 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Changed client's channel table to SilcList and changed code
4612 accordingly. Also changed SilcChannelClientEntry to include back-
4613 pointer to the channel so that client entry can use that structure
4614 as list as well and we have fast cross-reference to the channel.
4615 This change dramatically decreased the complexity of channel
4616 handling with client entry and vice versa (removed one extra
4617 loop when searching for channel entry from many functions).
4619 * Changed server->sim from table to SilcDList and changed code
4622 * NAMES command can now be used from user interface. It will show
4623 the user list on the channel, neatly.
4625 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4626 Code now saves realname of the user if it becomes available.
4628 * Renamed configure.in to configure.in.pre and made ./prepare
4629 script to automatically add correct version string to
4630 configure.in which it creates from configure.in.pre.
4632 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * NAMES command reply now shows users mode with the nickname when
4637 * Moved silc_client_ch[u]mode[_char] functions from
4638 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4639 place sucks, they are utility functions and should be in some
4642 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4644 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4647 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Added TRQ (efficient deque and list library) into lib/trq. This is
4652 a very good list library that is currently used in the SILC. Defined
4653 SilcList API over the library because I didn't like the API very
4654 much. See lib/trq/silclist.h for the API and examples of how to
4655 use the API. Fixed various places in the code to use the new
4656 SilcList API. The SilcList is meant for lists that has a structure
4657 already defined as a list. It is not suitable to add just some
4658 context to the list (in TRQ, the context is the list actually).
4660 So, I defined SilcDList that can be used for the purpose where
4661 predefined list structure does not exit. This can be used as
4662 such list. Now some context just can be added to the SilcDList.
4663 Currently this list is not used in the SILC just yet, though there
4664 are a lot places where this can replace dynamically allocated
4665 tables and I will fix these places, later, to use SilcDList.
4666 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4667 and use TRQ internally).
4669 Also fixed some annoying warning messages that the original TRQ
4670 code generated. Also minor changes to TRQ's Makefile.in.
4672 * Added support for querying by Client ID to both WHOIS and
4673 IDENTIFY commands into server, as required by the protocol.
4675 * Removed method function pointers from SilcBuffer structure. They
4676 weren't used to anything and just increased the context size for
4677 no good reason. This change also made silc_buffer_alloc and
4678 silc_buffer_free functions inline functions.
4680 * Disabled command flooding detection support until it's fixed so
4681 that it accepts commands in but does not execute them more than once
4684 * Added silc_net_localhost(), to return local hostname, into
4685 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4686 that must be initialized before calling silc_client_init.
4688 * Added new function: silc_server_send_notify_on_channels to send
4689 notify messages to all channels client has joined. It is assured
4690 that the message is sent only once per client.
4692 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4693 lib/silcutil/silcutil.[ch] as silc_format function. The new
4694 function is generic and is used by server as well, not only by
4695 the logging routines.
4697 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4698 the provided version string was not acceptable. Added new function:
4699 silc_ske_check_version into lib/silcske/silcske.h. The function
4700 must be implemented by the application (client or server) and it
4701 does not reside in the SKE library. The function checks the version
4702 string remote end sent.
4704 * Added back pointers (to opaque context and to SilcSocketConnection)
4705 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4707 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4708 duplicate packet context structure.
4710 * Changed `notify' client operation to send same arguments as client
4711 receives from server except for ID's. ID's are mapped to correct
4712 ID entry and that is returned. Also, if channel entry is not sent
4713 by server but the notify is for channel the channel entry is sent
4714 to application (otherwise application doesn't know that it is for
4715 channel (library gets it from packet's Destination ID)).
4717 * Added silc_client_remove_from_channels into client library to
4718 remove a client from all channels it has joined to. Used when
4719 received SIGNOFF notify from server. Added also new function
4720 silc_client_replace_from_channels to replace old ID entry with
4721 new ID entry on all channels. Used when received NICK_CHANGE
4724 * Fixed ID Cache list handling in silc_idlist_get_client in
4725 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4726 to get (or query) client by ID.
4728 * Updated TODO list.
4730 * Added connection authentication status message defined by the
4731 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4732 support for these into the code in client and server side.
4734 * Added generic function silc_client_send_command to send any command
4735 with variable argument list. Application should use this function
4736 to send commands if the command functions provided by the library
4737 does not suite for the application's user interface needs.
4739 * Added new `failure' client operation. Application is notified about
4740 received failure packet if client is executing a protocol. In this
4741 case the protocol's execution has failed.
4743 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4744 is required by the protocol.
4746 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4747 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4750 * Added status flag to SilcSKE object to indicate realtime status
4751 of the SKE protocol.
4753 * Application receives now exactly same command reply arguments as
4754 the library receives from server. However, if ID is received the
4755 corresponding ID entry is returned to the application (eg. Client
4756 ID is mapped to correct SilcClientEntry entry and that is returned).
4757 Changed command_reply client operation due to this change.
4759 * Changed all ID's in commands and in command replys as ID Payloads.
4760 Change affected both client and server side codes.
4762 All ID's sent in SILC network (with execption of ID's in SILC
4763 Packet header) are sent in ID Payload to support variable length
4766 * Server now notifies nick changes and notifies all clients on
4767 the channels about the new nickname (about the new Client ID,
4770 * Implemented CMODE command to change channel modes. Supports all
4771 channel modes defined by the protocol specs except ban and invite
4772 lists. (Also, private channel key mode is supported but support for
4773 setting private channel key in client is missing, thus, this mode
4774 has no effect on client side (except that server requires that the
4775 client uses private channel key and normal channel traffic does not
4778 Also, invite mode works per se, but INVITE command does not work
4779 yet correctly, so you can set channel as invite only channel but
4780 inviting clients to the channel does not work (it is yet to be
4781 thought what's the best way to do it).
4783 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4784 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4785 Implemented CUMODE command to change user's mode on the channel.
4786 Supports all modes defined by the protocol specs.
4788 * Added NAMES command reply to return users modes on the channel.
4790 * Removed unnecessary and slow ciphers from lib/silccrypt.
4792 * Set SO_KEEPALIVE option to connection sockets by default.
4794 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4796 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4797 redefined the Notify Payload into protocol specs.
4799 * Added silc_id_payload_parse_id to get ID directly from raw
4802 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4805 accept searching by Client ID as well.
4807 * Added support for LEAVE and SIGNOFF notify types in client library.
4809 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4810 to parse ID Payload from raw data.
4812 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Added flags parameter into silc_ske_assemble_security_properties
4815 function in lib/silcske/silcske.[ch].
4817 * Changed notify client operation to fit better for notify messages
4818 sent by server. The notify payload received from server is now
4819 passed to the application (after parsing it to SilcNotifyPayload).
4820 It is application's responsibility to retrieve the arguments
4821 from the payload and show the message the way it wants. The message
4822 sent by server is implementation specific.
4824 * Changed public keys to comply with the protocol specification.
4825 Old public keys are not supported anymore and are not compatible.
4827 * Removed nickname from Channel Payload as the latest draft removed
4828 it. The client must resolve the nickname from the NAMES command
4829 reply received when it joined the channel.
4831 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4833 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Fixed some errors in protocol specification drafts.
4837 * Created lib/silccore/silcnotify.c to implement Notify Payload
4838 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4839 generic payloads described by protocol specifications. The file
4840 includes implementations for ID Payload and Argument Payload.
4842 * Changed Command Payload implementation to use the new Argument
4843 Payload. Changed command_xxxx_payload to command_payload_xxxx
4844 to comply with SILC coding conventions.
4846 * Added suppport for Argument Payload handling in Notify Payload
4847 implementation as protocol requires it. Added the new support
4848 into server and client lib as well.
4850 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Added support for multiple nicknames on same channel. [n] is
4853 added locally to the nickname if there are more than one same
4854 nicknames on the channel.
4856 * Server now sends all nicknames that matched WHOIS request.
4857 Client also shows the list received from server.
4859 * Added TOPIC command to client side. User can now set and show
4860 current topic on channel.
4862 * Added MOTD command to client and server. Also, server sends the
4863 motd when client connects to the server.
4865 * Changed version strings to comply ISO 8601.
4867 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Fixed protocol error handling in client library. It should now
4870 cope even if the SKE fails for some reason.
4872 * Made new protocol specification drafts for submitting to IETF.
4874 * Implemented TOPIC command to server in silcd/command.c.
4876 * Added two new notify types into lib/silccore/silcnotify.h:
4877 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4878 notify nickname change and topic setting/change on a channel.
4880 * API change of command_reply operation in client library. The
4881 application gets now the status type received from server as well.
4883 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4887 * Cras fixed and optimized the packet handling even further and
4888 it should work now. Minor change to the prototype of function
4889 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4891 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Added new function into lib/silcutil/silcschedule.[ch]:
4894 silc_schedule_with_fd to select() a specified fd. The function
4895 returns after timeout expires or data arrives or goes. The
4896 function is used by packet routines to wait that all data is
4897 received from network.
4899 * Fixed data reading from network in lib/silccore/silcpacket.c.
4900 The code now assures that all data is read from the fd and then
4901 continues packet processing. This was a bug fix since the code
4902 used to drop some data in some circumstances.
4904 * Added new function into lib/silcclient/client.[ch]:
4905 silc_client_start_key_exchange to start key exchange after
4906 connection has been established to server. The code internally
4907 now uses this funtion but its main purpose was to provide it
4908 for applications that perform their own connecting. After
4909 application has created a connection it merely calls this
4910 function to start the key exchange between client and server.
4911 The library takes care of everything else after that.
4913 Updated also lib/silcclient/README to explain the usage of
4916 * Do not send to application information that connection has
4917 been established. Application gets notified it by connect
4920 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Applied cras's patch to add silc_schedule_one function. The
4923 function runs scheduler once and returns.
4925 * Fixed the scheduler after cras messed it up. The timeout
4926 handling works now as it's supposed to work.
4928 * Added into lib/silccore/ silcnotify.h to include notify
4929 message types support. Changed silc_server_send_notify*
4930 functions, in server.[ch], to support those new notify types.
4931 Added the support for the notify types into client library,
4932 as well. Added new notify client operation into ops.h in
4935 * Changed silc_server_packet_send_to_channel to send normal
4936 packets instead of just channel message packets. The function
4937 is now used to send the notify packets to channels. It is not
4938 used to send channel message packets anymore, as server never
4941 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4942 va_arg()s as it seems to require it nowadays. I guess, if SILC
4943 is compiled with older va_arg() the new code should work anyway.
4945 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Splitted core library. Core library (lib/silccore) includes
4948 now only SILC protocol specific core (and common) components.
4949 Created new utility library (lib/silcutil) that includes more
4950 generic purpose stuff. The stuff for util library was taken
4951 from the old core library. This was minor and easy split.
4953 * Created SILC Client Library (lib/silcclient) that includes
4954 implementation of the SILC client without user interface. This
4955 was major move from silc/ directory. The code has been changed
4956 so that it is transparent towards the user interface. The
4957 silc/ directory includes now the same user interface as before
4958 and it uses the new client library. Read lib/silcclient/README.
4959 Basicly, the client library performs everything else related
4960 to SILC except user interface handling. Also, configuration
4961 files are considered to be part of user interface and library
4962 does not handle them.
4964 This change also changed a lot of structures, function naming etc.
4965 Most important change was that SilcClientWindow object was
4966 renamed to SilcClientConnection in the client library. Created
4967 also new file lib/silcclient/ops.h. Also added new files
4968 silc/local_command.[ch] and silc/client_ops.[ch].
4970 All these changes were made to make it easier for user interface
4971 designers to create what ever user interface for the SILC client
4974 It is also expected that the server will be moved to lib
4975 directory as well and SILC Server Library will be created;
4976 sometimes in the future.
4978 * Removed Local commands from lib/silccore/silccommand.h as
4979 they are application specific and new client library does not
4980 handle any of those anymore.
4982 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4983 old client implementation in silc/.
4985 * Added support for callback functions in SILC_LOG_* macros.
4986 Application can now set its own callbacks that will be called
4987 instead of using the default functions that will always print
4988 the debug messages to stderr (or stdout). Also, debugging can
4989 now be disabled by setting silc_debug to FALSE and re-enabled by
4990 setting it to TRUE. Note, that logging will still work even
4991 if debugging is disabled.
4993 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4994 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4995 silc_log_reset_debug_callbacks.
4997 * To enable debugging in silc client one must give now -d
4998 option on command line.
5000 * Changed silc_schedule_init to automatically allocate task queues
5001 if they are not allocated before calling it.
5003 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Added GMP 3.1 into math library.
5007 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5010 a channel in SILC network. The packet is used by servers and
5011 routers to notify other routers that user has left a channel.
5012 This little feature was missing until now. Added the feature
5013 to protocol specification as well.
5015 Added functions: silc_server_send_remove_channel_user and
5016 silc_server_remove_channel_user into server.[ch].
5018 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5019 lib/silccore/silcpacket.h. However, they are not implemented
5022 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Fixed joining to a channel and sending channel messages
5025 between server and router. The channel message sending should
5026 now work inside a cell.
5028 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Fixed the private message sending between server and router.
5031 The private message sending should now work inside a cell.
5033 * Added silc_server_replace_id into server.[ch] to replace
5034 existing ID in the SILC network.
5036 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5037 and silc_idlist_replace_server_id into idlist.[ch] in server.
5039 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Fixed the server to server connections. Server can again now
5042 connect to router. Router to router connections probably does
5045 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Added dynamic protocol registering support. Now protocols can
5048 registered and unregistered on the fly. Patch by cras.
5050 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Added lib/contrib directory to hold routines that some platforms
5053 don't have but are needed by SILC.
5055 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5056 into lin/contrib to provide getopt() and getopt_long() for
5057 those who don't have it.
5059 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Added AWAY command to client. When away message is set and
5062 client receives a private message packet the client automatically
5063 replies to the sender with the away message.
5065 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5066 bug seemed to be the cause of recent problems when compiling
5069 * Added version detection support to SKE protocol specification
5070 and added the new changes to the SKE implementation as well.
5071 There were other minor changes in the SKE protocol as well.
5073 Many changes in lib/silcske/silcske.[ch] and in
5074 lib/silcske/payload.[ch].
5076 * Added ^U functionality, clear input line. Patch from cras.
5078 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Mainly small bugfixes on core library. Fixed some debugging
5081 logging and buffer overflow in silclog.c.
5083 * Updated config.sub and config.guess on the distribution tree.
5085 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added command lagging support in server. Client may execute
5088 commands now only once in two seconds.
5090 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Optimized packet reception. MAC computation and checking is now
5093 also more optimized. A lot previously duplicated code is now
5094 used as generic by both client and server.
5096 * Fixed key pair generation in clientutil.c
5098 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Added into lib/silccore/silcbufutil.[ch] new function;
5101 silc_buffer_realloc.
5103 * Moved generic packet sending/encryption functions to
5104 lib/silccore/silcpacket.[ch] from client and server. Some
5105 rewriting of the functions.
5107 * Moved all generic packet reception/decryption functions to
5108 lib/silccore/silcpacket.[ch] from client and server. The
5109 packet processing is now much cleaner in both client and server.
5110 These were major changes in both client and server.
5112 * Created many common functions in server to do packet sending.
5113 Previously code were duplicated a lot, this has been removed
5116 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Rewrote major parts of the ID cache system. Don't know
5119 whether it is better now or not but at least the API is more
5122 * Major rewrite on ID cache stuff on client because of the ID
5123 cache API changes. Added idlist.c to client.
5125 * Also major rewrite on ID cache stuff on server as well.
5126 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5127 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5128 in hand, instead they are all put into the ID cache system now.
5129 All server_idlist_* routines uses ID cache now instead of
5130 traversing its own lists (those lists does not exist anymore).
5131 SilcIDList though still exists. Also, SilcXXXEntry's are
5134 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Finally made the SKE implementation compliant to the protocol
5137 specification. All mp integers are now binary encoded as
5138 opposed being HEX encoded.
5140 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5143 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5144 functions: silc_[encode/decode]_pem. Also added function
5145 silc_encode_pem_file to PEM encode with newlines ('\n') for
5148 * SILC public keys are now encoded either PEM or binary. Same
5149 option is for private keys as well. By default private keys
5150 are binary encoded and public keys PEM encoded. Silly HEX
5151 encoding were removed.
5153 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5154 function to create fingerprints.
5156 * Fixed a bug in SHA1; does not change the original data anymore.
5158 * Partly implemented INFO command on client and server side.
5159 Fixed CLEAR command. Changes to SERVER command; show current
5160 server(s) when giving command without arguments. Added
5161 VERSION command to client.
5163 * Added check to server that unregistered connections cannot
5164 execute commands (unless it is specificly allowed).
5166 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Fixed screen refresh.
5170 * Fixed channel joining bug from client. On some circumstances
5171 client tried to join to a channel it had already joined.
5173 * Added public key verification process into client's protocol.c.
5174 The client now verifies the public key from user and saves
5175 it into ~./silc/serverkeys/ directory.
5177 Added into: clientutil.[ch]: silc_client_verify_server_key.
5179 * Changed SKE protocol's silc_ske_initiator_finish function
5180 to accept callback function that verifies the received public
5181 key. Removed old silc_ske_verify_public_key function.
5183 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5186 silc_pkcs_private_key[_data]_set.
5188 * Made the password and public authentication more cleaner in
5189 server's protocol.c.
5191 * Removed historic and obsolete protocol `channel_auth' from
5192 both client and server.
5194 * Removed wrong way of sending command status messages from
5195 server to client in server's command.c. The old way violated
5196 protocol specification.
5198 Changes to silccore/silccommand.[ch]: removed
5199 silc_command_encode_status_payload -> not needed anymore,
5200 changed silc_command_encode_payload_va to accept extra
5201 argument on variable argument list. The argument type must
5202 now be provided to the function. Also, added new function:
5203 silc_command_encode_reply_payload_va which is same as
5204 normal command_encode_payload_va except command status type
5205 is provided as extra argument.
5207 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Added ~./silc directory handling. The directory includes the
5210 public and private keys for the client.
5212 Added silc_client_check_silc_dir, silc_client_create_identifier
5213 and silc_client_load_keys.
5215 * Implemented SILC protocol compliant public key. Added public
5216 and private key saving to and loading from files.
5218 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5219 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5220 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5221 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5222 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5224 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5225 silc_pkcs_load_[public/private]_key.
5227 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Added silc_server_get_route (route.[ch]) to get connection
5230 data for the fastest route for given ID.
5232 * Implemented INVITE command on client and server. The command
5233 were re-defined in the SILC Protocol Specification and the
5234 implementation now complies with the specification.
5236 * Implemented PING command on client and server.
5238 * Implemented NAMES command on client and server. The server side
5239 supports currently only normal server not router server yet.
5240 Some changes to NAMES definition in SILC protocol specification.
5242 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Implemented LEAVE command on client and server.
5246 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5247 again. This change was made to the protocol as well. Server
5248 should not violate the protocol specification anymore.
5250 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5253 was tested. SOCKS4 was not but should work anyway.
