1 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * When printing the channel mode on JOIN, verify that the
4 channel key and channel's HMAC are valid. Affected file
5 irssi/src/silc/core/client_ops.c.
7 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
10 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
11 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
13 * Removed channel key rekey task deleting from the function
14 silc_server_save_channel_key. Affected file silcd/server.c.
15 Added explicit timeout task context instead that is used to
16 delete the task if we are registering a new task before the
19 * When channel key rekey occurs the client library now saves
20 the old channel key for a short period of time (10 seconds) and
21 is able to use it in case some is still sending channel
22 messages encrypted with the old key after the rekey. Affected
23 file lib/silcclient/[idlist.h|client_channel.c].
25 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
27 * Added check to the silc_server_new_id_real to not accept
28 new ID if it is the sender's own ID. Affected file is
29 silcd/packet_receive.c.
31 * Assure that we do not announce ourself or the one we've
32 sending our announcements when we're router and are announcing
33 servers to our primary router. Affected file silcd/server.c.
35 * Fixed silc_server_command_identify_check_client to assemble
36 correct WHOIS packet. It send corrupted WHOIS packet and
37 caused problem with router to router connections. Affected
40 Fixed also silc_server_command_whois_check the same way
41 as for the IDENTIFY command.
43 * Added new SilcIDListStatus to the server in the SilcIDListData
44 structure. The status now includes the current status of
45 the entry (like registered, resolved etc.). Affected file
46 silcd/idlist.[ch]. Defined a bunch of different status types
47 as well. This replaced the old boolean registered field as well.
49 Added resolve_cmd_ident field to the SilcClientEntry structure
50 too so that if the entry is for example being resolved so
51 another command may attach to the same pending command reply
52 without requiring to resolve the same entry again. This concept
53 should optimize the WHOIS and the IDENTIFY resolving under
54 heavy load by taking away unnecessary resolving for entries
55 that are being resolved already.
57 Added support for adding multiple pending commands for one
58 command idenfier. Affected file silcd/command[_reply].[ch].
60 * Fixed WHOIS and IDENTIFY save to remove the cache entry
61 before deleting the data. Otherwise the hash table will have
62 freed data in comparison functions. Affected file is
63 silcd/command_reply.c.
65 * Fixed silc_idlist_replace_client_id to add the new entry to
66 the cache with NULL nickname. Otherwise there will be invalid
67 memory as the nickname after the nickname is freed. Affected
68 file silcd/packet_receive.c.
70 * Fixed the silc_idlist_get_clients_by_hash. The entries was
71 saved into wrong slots because the previous number of entries
72 was not taken into account. Affected file silcd/idlist.c.
73 Fixed same thing in silc_idlist_get_clients_by_nickname too.
75 * If we are router and we receive JOIN notify to a channel that
76 does not have any users then notified client is marked as the
77 channel founder, as it is it. The affected file is
78 silcd/packet_receive.c
80 * Added to the extended hash table API's table_del_*ext functions
81 the destructor as argument too, so that the caller can decide
82 which destructor to use or whether to use destructor at all.
83 Affected file lib/silcutil/silchashtable.[ch].
85 * Fixed ID Cache purging. It actually deleted the entries from
86 the hash table after the data was freed. The hash table ended
87 up comparing freed memory. The affected file is
88 lib/silccore/silcidcache.c.
90 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
92 * Fixed Irssi SILC client's KILL command's HELP syntax.
94 * The USERS command now resolves the detailed user information
95 if the userinfo field is missing. Affected file is
96 lib/silcclient/command_reply.c.
98 * Do not print error in silc_file_read if the read file does
99 not exist. Just silently return NULL. Affected file is
100 lib/silcutil/silcutil.c.
102 * Fixed the silc_log_output to not wine about NULL filename
103 and to not create some bogus " " filename. Affected file is
104 lib/silcutil/silclog.c.
106 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
108 * Fixed various printing bugs on the user interface in the
109 Irssi SILC Client. Minor changes that were forgotten from
112 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
114 * Fixed the configure.in.pre and the compilation and distribution
115 environment to support the new autoconf 2.52. That version is
116 now required to compile the CVS trunk.
118 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
120 * Renamed function silc_parse_nickname to silc_parse_userfqdn
121 to generally parse user@fqdn format strings. Affected file
122 lib/silcutil/silcutil.c.
124 * Added nickname_format and nickname_force_format fields to the
125 SilcClientParams structure. The first one defines the format
126 for the nicknames that the library will enforce if the receives
127 multiple same nicknames. The second one is boolean value and
128 can be used to force the library to always enforce the format
129 to the nicknames regardles whether there are multiple nicknames
130 or not. This configurable formatting was employed to flexibly
131 support accessing multiple nicknames from the user interface.
132 The userinterface can now set the nicknames to what ever format
133 they prefer. Affected file lib/silcclient/silcapi.h.
135 Added function silc_client_nickname_format to the file
136 lib/silcclient/idlist.c. It performs the nickname formatting.
138 Added new field `hostname´ to the SilcClientEntry context.
139 It holds the hostname of the client. Affected file is
140 lib/silcclient/idlist.h.
142 * Irssi SILC Client sets the nicknames in nick@hostn format.
143 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
144 irssi/src/silc/core/silc-core.c.
146 The WHOIS printing now also shows both the real nickname and
147 the formatted nickname so that user knows how to access the
148 user if there are multiple same nicknames cached. Affected
149 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
150 printing formatting too to take the hostname now as a separate
151 argument. The Affected file is
152 irssi/src/fe-common/silc/modules-formats.[ch].
154 * Changed the silc_client_get_clients_local to accept the formatted
155 nickname as argument. It accepts the real nickname too but the
156 formatted nickname can be used to find the true entry from
157 multiple entries. Affected file lib/silcclient/silcapi.h and
158 lib/silcclient/idlist.c.
160 * Added nickname_format_parse field to the SilcClientParams.
161 It is a callback function provided by the application to parse
162 the nickname out of the formatted nickname string. The library
163 calls it to get the nickname from the formatted string. Since
164 the application generally knows better the format of the nickname
165 string it parses it instead of the library, even though library
166 encodes the formatted string. If the callback function is not
167 provided then the library will use the string as is. The
168 affected file is lib/silcclient/silcapi.h.
170 * All the nickname strings passed to the client library in
171 commands are now expected to be formatted nickname strings.
172 If the command does not support the formatted nickname string
173 it will assume that the sent string is the actual nickname.
174 Affected file lib/silcclient/command.c.
176 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
178 * Added public key authentication support to OPER and SILCOPER
179 commands in the client library. Affected file is
180 lib/silcclient/command.c.
182 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Changed the get_auth_methdod client operation to be asynchronous.
185 It can be async if the application resolves the authentication
186 method from the server during the negotiation. Added new
187 SilcGetAuthMeth completion callback that the application will
188 call after resolving the authentication method.
190 Added function silc_client_request_authentication_method that
191 the application can use to resolve the authentication method
192 from the server. Added also SilcConnectionAuthRequest callback
193 that the library will call after the server has replied. The
194 application can call this function if it does not know the
195 current authentication method.
197 Affected files are lib/silcclient/client.c and
198 lib/silcclient/silcapi.h.
200 * The Irssi SILC client now automatically resolves the authentication
201 method incase any configuration information is not present (and
202 currently there never is). The affected file is
203 irssi/src/silc/core/client_ops.c.
205 * Fixed public key authentication from the client library.
206 Affected file lib/silcclient/protocol.c. Changed also the
207 protocol specification about the public key authentication in
208 the connection authentication protocol. The actual data to be
209 signed is now computed with a hash function before signing.
211 * Fixed the public key authentication from the server as well.
212 Affected file silcd/protocol.c.
214 * Removed the mlock()'s from the memory allocation routines.
215 Affected file lib/silcutil/silcmemory.c. The ./configure does
216 not check anymore for the mlock(). Affected file is
219 * Fixed USERS command in server to allow the execution of the
220 command for private and secret channels if the client sending
221 the command is on the channel. Affected file silcd/command.c.
223 * Fixed silc_client_get_clients_local to return the clients
224 count correctly. It could return wrong value. Affected file
225 lib/silcclient/idlist.c.
227 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
229 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
230 types. The assembler optimizations seemed not to like 64-bit
231 data types. The assmebler optimizations thus are now enabled
232 also for BSD systems as opposed to only enable them for Linux.
234 * Do not check for threads at all on BSD systems. Affected
235 file configure.in.pre.
237 * Removed -n and -h options from the Irssi SILC Client since
238 they are not used in silc.
240 * Fixed the prime generation to assure that the first digit
241 of the generated random number is not zero since our conversion
242 routines does not like number strings that starts with zero
243 digit. If zero digit is seen the random number is regenerated.
244 This caused some corrupted RSA keys when the zero first digit
245 was met. Affected file lib/silcmath/silcprimegen.c.
247 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
249 * Fixed WIN32 configuration in the ./configure script.
250 Fixed to include xti.h on environments that has it.
251 Patches by Carsten Ilchmann and andrew.
253 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
255 * Changed the silc_id_create_client_id to be collision
256 resistant. It is now assured that there cannot be created
257 two same client ID's. I suspect that some weird bugs in
258 the server were actually caused by duplicate Client IDs.
259 Affected file silcd/serverid.[ch]. A router receiving
260 new ID now also assures and informs the sending server
261 if the ID caused collision.
263 * Changed the silc_id_create_channel_id to also assure that
264 there are no collisions.
266 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
268 * Statement about ignoring the Mutual Authentication flag when
269 performing rekey with PFS was a bit misleading. It is ignored
270 if it was set in the initial negotiation, it cannot be even
271 set in the rekey. Fixed in the ke-auth draft. Started the
272 new versions of the protocol drafts in the doc/.
274 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
276 * Fixed a bug in silc_client_command_identify_save when saving
277 new channel information. The channel name was no duplicated
278 and caused crash on exit. Affected file is
279 lib/silcclient/command_reply.c.
281 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
283 * Fixed the getkey command handling in the server. Send just
284 empty OK reply to the sender if the key could not be fetched
285 (but everything else was ok, like the key just was not available).
286 Changed the public key parameter to optional in the protocol
287 specs so that empty OK reply can be sent. Affected file
290 Added a message to Irssi SILC client to tell to user if the
291 server did not return a public key.
293 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
295 * Fixed a channel key regeneration bug. It registered new
296 timeout tasks exponentially until all system resources were
297 used. Affected file silcd/server.c.
299 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
301 * Added the SILC Document generator to the scripts/silcdoc.
302 It can be used to generate the Toolkit Reference Manual out
303 of the source tree. Internally it will also use the RoboDoc
304 generator now imported in util/robodoc.
306 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
308 * Added couple of return's in rekey protocol if error orccurred
309 during the protocol. The execution must be terminated.
310 Affected file silcd/protocol.c. Also, terminate the protocol
313 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
315 * The client's Client ID was created initally from the wrong
316 nickname (it could have been in format nick@host) in the
317 silc_server_new_client. Affected file silcd/packet_receive.c
319 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
321 * Added some SILC_LOG_ERROR's to various error conditions
322 if client could not be added to ID cache. Affected files
323 silcd/packet_receive.c and silcd/server.c.
325 * When client's sock->user_data is freed, NULL also the
326 client->router and client->connection pointers. Added check
327 for these pointers being NULL to various places around the
328 code. Affected file silcd/server.c.
330 * Added client->data.registered == TRUE checks to various
331 places around the code to assure that unregistered client's
332 are not handled when it is not allowed. Affected file
335 * Added `bool registered' fields to all
336 silc_idlist_[server|client]_get_* routines to indicate whether
337 the fetched client needs to be registered or not. Affected
338 file silcd/idlist.[ch].
340 * Add your own entry as registered to the ID cache in the
341 server. Affected file server.c.
343 * Fixed a bug in silc_server_new_server. The SilcServer was
344 set as the new server's context instead of SilcServerEntry.
345 This naturally caused some weird bugs.
347 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
349 * Do not delete the channel rekey task when adding it
350 for in silc_server_create_channel_key.
352 * Changed the silc_server_create_channel_key to return
353 TRUE or FALSE to indicate the success of the channel key
356 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Fixed MSVC++ project files and added missing files to
359 Makefiles under win32/.
361 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Do not add TCP_NODELAY flag if the operating system
364 does not have it defined. Affected files are
365 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
367 * Fixed buffer overflow from Irssi SILC Client. Affected
368 file irssi/src/fe-common/core/themes.c.
370 * Fixed double free in client library in the file
371 lib/silcclient/client.c when disconnecting from server.
373 * Applied double free patch from cras to Irssi SILC client.
374 Affected files irssi/src/core/[modules/expandos].c
376 * Fixed the disconnection handling to Irssi SILC Client.
377 The application must call silc_client_close_connection
378 in ops->connect client operation in case of failure of
379 the connection. Affected file is
380 irssi/src/silc/core/client_ops.c.
382 * Do not set sock->protocol to NULL in the function
383 silc_client_close_connection after executing the protocol's
384 final callback since the sock might not be valid anymore.
385 Affected file lib/silcclient/client.c.
387 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
389 * Do not enable SILC_THREADS if the linking with libpthread
390 did not happen. Affected file configure.in.pre.
392 * Added notion to protocol specification that server must
393 verify the sent authentication payload with CMODE when
394 setting the channel founder key. Implemented it to the
395 server. Affected file silcd/command.c.
397 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
399 * Added _EXTRA_DIST SILC distribution variable to the
400 distributions file. It is used to conditionally add extra
401 files or directories to the specific distribution. Affected
402 files ./prepare, Makefile.am.pre and distributions.
404 Removed the `_' from the start of the distribution names.
407 * Added README.WIN32 for instructions to compile the Toolkit
410 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
412 * Fixed a double free in disconnection in the server. Affected
413 file is silcd/server.c.
415 * Fixed the lib/silcske/groups.c to work now also with GMP
416 MP library. The string conversion did not work when using
417 specific base and the base is indicated in the string as well.
419 * Created win32/ directory which now includes MSVC++ specific
420 stuff so that toolkit (DLLs) may be compiled with MSVC++.
421 It will appear only in the toolkit distribution
423 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
425 * Changed the key material distribution function in case when
426 the hash output is too short. The data is now concatenated
427 a bit differently than it used to. Made the change to the
428 SKE protocol specification.
430 * Added better GMP detection to configure.in.pre. A patch
433 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
435 * Fixed a minor bug in SKE that might cause some problem on
436 some platforms. Affected file lib/silcske/silcske.c.
438 * Added the cookie checking for initiator in the SKE. It checks
439 that the responder returns the sent cookie unmodified. The
440 affected file is lib/silcske/silcske.c. Added new SKE
441 error type INVALID_COOKIE that can be sent during the
442 negotiation. Fixed some memory leaks as well.
444 * Added the "invalid cookie" error message to Irssi SILC client's
447 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
449 * Added `task_max' field to the SilcClientParams to indicate
450 the maximum tasks the scheduler can handle. If set to zero,
451 default values are used. Affected file lib/silcclient/silcapi.h.
453 * Fixed memory leaks in silc_client_close_connection. Affected
454 file lib/silcclient/client.c.
456 * Added silc_client_del_client_entry to client library to free
457 all memory of given client entry. Affected file is
458 lib/silcclient/idlist.[ch].
460 * Added new functions silc_client_del_channel and
461 silc_client_del_server to delete channel and server entries.
462 Affected file lib/silcclient/[silcapi.h/idlist.c].
464 * Removed silc_client_del_client_by_id from silcapi.h.
466 * Fixed the INFO command to return the server's own info
467 correctly when querying by Server ID. Affected file is
470 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
472 * Removed the non-blocking settings in WIN32 code in the
473 silc_sock_[read/write] and added SleepEx instead. Affected
474 file lib/silcutil/win32/silcwin32sockconn.c. The availability
475 of input data is now checked with FIONREAD and ioctlsocket.
477 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
479 * Call silc_schedule_task_del_by_context in the
480 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
481 Affected file lib/silccore/silcprotocol.c.
483 * Call silc_protocol_cancel for active protocols in the
484 silc_server_close_connection if the funtion
485 silc_server_free_sock_user_data has not been called.
486 Affected file silcd/server.c.
488 * Generic tasks cannot be deleted using the del_by_fd
489 task deleting function since generic tasks does not match
490 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
492 * Added a notion to SILCOPER help file that the SILCOPER works
493 only on router server, not on normal server.
495 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
497 * Added for WIN32 support for the new scheduler as well.
498 Affected file lib/silcutil/win32/silcwin32schedule.c.
500 * Fixed the SHA1 implementation to work on various platforms.
502 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
504 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
505 API. It is part of the scheduler now. Everything else is
506 as previously but some functions has changed their names.
507 Checkout the lib/silcutil/silcschedule.h for the interface.
508 Updated all applications to use the new interface. Affected
509 files are lib/silcutil/silcschedule.[ch].
511 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
513 * Found a bug in the SKE implementation. The HASH value,
514 specified by the protocol, was not computed correctly. The
515 public key of the responder was not added to the computation
516 even though it is mandatory. Affected file lib/silcske/silcske.c.
517 This unfortunately causes incompatibilities with older
520 * Added WIN32 specific network init and uninit functions:
521 silc_net_win32_init and silc_net_win32_uninit to init and uninit
522 the Winsock2. Affected file lib/silcutil/silcnet.h and
523 lib/silcutil/win32/silcwin32net.c.
525 * Set the socket always to nonblocking mode on WIN32 after
526 reading data or writing data. Affected file is
527 lib/silcutil/win32/silcwin32sockconn.c.
529 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
531 * Fixed various compilation problems under WIN32. Affected
532 files lib/silcutil/win32/silcwin32thread.c and
533 lib/silcutil/win32/silcwin32schedule.c.
535 * Removed all _internal.h #includes from public header
536 files. Internal headers must never be included from
539 Removed also the lib/silcske/payload_internal.h file.
541 * All include files that may be needed (public and some others
542 included by the public headers) by application developers are
543 now copied to the ./includes directory. It does not copy any
544 internal headers. Affected file Makefile.defines.pre and all
545 Makefile.am's under lib/ and subdirs.
547 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Do not change the ~/.silc directory's permissions automatically.
550 Affected file irssi/src/silc/core/clientutil.c.
552 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
554 * Do not cancel the protocol in silc_server_close_connection
555 it might cause recursion. Now cancelled in the function
556 silc_server_free_sock_user_data. Affected file silcd/server.c.
558 * Fixed the silc_server_remove_clients_by_server to regenerate
559 the channel keys correctly finally. Added also new function
560 silc_server_remove_clients_channels to actually do it.
561 Affected file silcd/server.c.
563 * Fixed the silc_server_new_channel to not crash by giving
564 wrong router to the new channel. Affected file is
565 silcd/packet_receive.c.
567 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
570 which is given as argument to the silc_client_alloc now.
571 It can be used to configure the client and set various parameters
572 that affect the function of the client.
574 * The USERS command in server did not check whether the channel
575 is private or secret. Affected file silcd/command.c.
577 * Added new argument to the USERS command in protocol specification.
578 The USERS command now can take the channel name as argument
579 as well. Added support for this in client and server and
580 updated the protocol specs.
582 * Completed the GETKEY command in client. It can be now used
583 to fetch also servers public key not only some clients.
584 Affected files lib/silcclient/command[_reply].c.
586 * Added silc_client_get_server to return server entry by the
587 server name. Affected files lib/silcclient/silcapi.h and
590 * Redefined the IDENTIFY command in protocol specification to be
591 more generic. It now can be used to query information about
592 any entity in the SILC Network, including clients, servers and
593 channels. The query may be based either the entity's name
594 or the ID. Added support for this in both client and server.
596 Affected files silcd/command.c and lib/silcclient/command.c
599 * Optimized the WHOIS and WHOWAS commands in the server. Removed
600 the _from_client and _from_server functions. Affected file
603 * Added silc_client_get_channel_by_id_resolve to the file
604 lib/silcclient/silcapi.h to resolve channel information by
605 its ID. Added also silc_client_get_channel_by_id that
606 does not resolve it from the server.
608 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Added SilcServerEntry context into the client library
611 to represent one server. The INFO command now allocates
612 these to save the resolved server info. For now on the
613 client library will also keep information about servers,
614 connected and resolved with INFO.
616 The INFO command now allocates the SilcServerEntry context
617 and saves the server info there. The COMMAND_REPLY in
618 the INFO now returns the parameters to application in
619 same order as defined in the protocol specification.
621 The entries are cached in the client->server_cache.
623 * The INFO command is now issued after received the Client ID
624 from the server. Affected file lib/silcclient/client.c.
626 * The CMODE_CHANGE notify may now return also an SilcServerEntry
627 to the application as the mode changer might be server.
628 It is guaranteed that NULL is not returned anymore to the
629 application. Affected file lib/silcclient/client_notify.c.
631 The ID Type is now also passed to the application so that
632 it can check whether the returned entry is SilcClientEntry
635 Added new function silc_client_get_server_by_id to return
636 the server entry by ID. Affected files are the
637 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
639 * Do not create the channel in the Irssi SILC Client when issuing
640 the JOIN command but when received the sucessful JOIN command
641 reply. Otherwise the channel might get created even though we
642 could not join it. The Affected file is
643 irssi/src/silc/core/[silc-channels.c/client_ops.c].
645 * Fixed a channel joining bug in router. The router must also
646 check the channel modes, invite and ban lists etc. when serving
647 the JOIN command sent by normal server. Affected file is
648 silcd/command.c. The router now resolves the client's
649 information from the server who sent the JOIN command if it
650 does not know it, and processes the JOIN command only after
653 * Changed the SilcCommandCb to take new argument; void *context2.
654 Affected file lib/silccore/silccommand.h
656 The second argument in the command callbacks in the server now
657 includes the SilcServerCommandReplyContext if the command was
658 called as pending command callback from the command reply.
659 Otherwise it is NULL. When called as pending the status of the
660 command reply will be checked and if it was erronous the
661 error will be sent to the original sender of the command.
662 This way the client always receives the error messages even
663 though the server was actually the one who received the error
664 when it resent the command to router, for example. Affected
665 files silcd/command[_reply].[ch].
667 * Fixed sending WHOWAS command's error message to client if
668 the requested client could not be found. It was missing.
671 * Changed the CMODE and CUMODE commands reply arguments in the
672 protocol specification. The Channel ID is now sent in both
673 of the commands to identify the channel. Implemented this
674 new feature to the client and server. Affected files
675 lib/silcclient/command_reply.c and silcd/command.c.
677 * Made better checks for invite and ban lists in the JOIN
678 command in server. Affected file silcd/command.c.
680 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
682 * The server now performs the incoming host IP/DNS lookup
683 using the silc_socket_host_lookup and thus does not block
684 the server anymore. Affected file silcd/server.c.
686 * Completed the multi-thread support for SILC Scheduler in
687 the lib/silcutil/silcschedule.c.
689 * Fixed the configure.in.pre to detect the pthread correctly
692 * Fixed a deadlock in silc_task_queue_wakeup in the file
693 lib/silcutil/silctask.c.
695 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Added new function silc_schedule_wakeup that is used in
698 multi-threaded environment to wakeup the main thread's
699 schduler. It needs to be used when a thread adds a new task
700 or removes a task from task queues. After waking up, the
701 scheduler will detect the task queue changes. If threads
702 support is not compiled in this function has no effect.
703 Implemented the wakeup mechanism to both Unix and WIN32
704 systems. Affected files are lib/silcutil/silcschedule.[ch],
705 lib/silcutil/unix/silcunixschedule.c and the
706 lib/silcutil/win32/silcwin32schedule.c.
708 * Added new function silc_task_queue_wakeup to wakeup the
709 scheduler by the specified task queue. Affected file
710 lib/silcutil/silctask.[ch].
712 * The silc_socket_host_lookup_start now wakes up the scheduler
713 after adding the timeout task. Affected file is
714 lib/silcutil/silcsockconn.c.
716 * The silc_socket_host_lookup is synchronous now if the threads
717 support is not compiled in. However, the callback is still
718 called asyncronously through the scheduler, anyway. Affected
719 file lib/silcutil/silcsockconn.c.
721 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
723 * Added new function silc_socket_host_lookup to perform
724 asynchronous IP and FQDN lookups for the socket connection.
725 Affected files lib/silcutil/silcsockconn.[ch].
727 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
729 * Added SILC_MUTEX_DEFINE to define the mutex on environments
730 that may or may not compile the mutex support in.
732 Changed the silc_mutex_alloc interface. It allocates the
733 mutex now to the sent pointer and returns TRUE or FALSE.
735 Affected file lib/silcutil/silcmutex.h.
737 * Wrote the SILC Task Queue interface to support multi-threads.
738 Affected file lib/silcutil/silctask.[ch].
740 * Wrote the SILC Scheduler to support multi-threads. Affected
741 file lib/silcutil/silcschedule.c.
743 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
745 * Implemented the SILC Mutex API and SILC Thread API for WIN32
746 in lib/silcutil/win32/.
748 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
750 * Defined SILC Mutex API and SILC Thread API and implemented
751 them for Unix. Affected files are
752 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
753 lib/silcutil/unix/silcunixmutex.c and
754 lib/silcutil/unix/silcunixthread.c.
756 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
758 * Fixed the silc_server_remove_clients_by_server's channel
759 key re-generation. The hash table handling was incorrect
760 and would not work with many channels. Affected file is
763 * Fixed some memory leaks around the server code.
765 * Rewrote the silc_server_get_users_on_channel to support IPv6
766 based Client ID's. Affected file silcd/server.c.
768 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
769 specification. However, a separate document must be written
770 to define the detailed signing procedure and the payload
771 associated with the flag. Defined the flag to the
772 lib/silccore/silcchannel.h as well.
774 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
776 * Changed the dynamic tables to static size tables in the
777 lib/silccrypt/silchmac.c.
779 * Removed GCC dependencies from the code. A patch by cras.
781 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Do not show the error "Error receiving packet bla bla"
784 in server if it really was not an error (-2 means that reading
785 is pending). Affected file silcd/server.c.
787 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
789 * Fixed a possible crash in silc_server_remove_clients_by_server
790 in silcd/server.c. Fixed there also some memory leaks.
792 * Fixed the silc_idlist_replace_client_id. It could replace
793 wrong key in the hash table. Affected file silcd/idlist.c.
795 * Do not check whether there are global users on the channel
796 if the channel->global_users is FALSE. Affected functions
797 silc_server_remove_from_one_channel and
798 silc_server_remove_from_channels in silcd/server.c. Also,
799 do not check if the removed client is local as we can be
800 sure that global client was not removed from the channel
801 and checking for global users is not needed.
803 * The silc_server_remove_clients_by_server now re-generates
804 the channel keys correctly for those channels that had
805 clients removed from them. Affected file silcd/server.c.
807 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Found the reason of random crashes in the server. We weren't
810 ignoring the SIGPIPE signal (which can be sent in write())
811 and it crashed the server. Affected file silcd/silcd.c.
813 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Assure that sock->user_data is not NULL in the function
816 silc_server_packet_send in silcd/packet_send.c.
818 * Disconnect the remote connection if it could not be added
819 to any ID lists in the server. The affected file is
822 * Check in silc_server_packet_send[_real/dest] that the
823 socket is not disconnecting and ignore the data if it is.
824 Affected file silcd/packet_send.c.
826 * Define inline to __inline on native WIN32 compilation.
827 Affected file includes/silcwin32.h.
829 * Added some explicit type casts for inline code since MSVC
830 require them. Affected files lib/silcutil/silcbuffer.h,
831 lib/trq/silcdlist.h and lib/trq/silclist.h.
833 * Print warning in log files from now on if the packet
834 decryption fails. Affected file silcd/server.c.
836 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
838 * Changed the `say' client operation's interface to accept
839 new `type' argument to indicate the type of the message sent
840 by the library. The application may filter the library's
841 messages according the type. The affected file is the
842 lib/silcclient/silcapi.h.
844 * Added two new functions to lib/silcclient/silcapi.h:
845 silc_client_del_client and silc_client_del_client_by_id.
846 Affected file lib/silcclient/idlist.c.
848 * Moved the clientincludes.h from includes/ to silc/ and
849 serverincludes.h from includes/ to silcd/.
851 * The modes for the CMODE and CUMODE are now passed as
852 uint32 for application with COMMAND_REPLY. The affected
853 file is lib/silcclient/command_reply.c.
855 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
857 * /WHOIS without arguments shows client's own information.
858 Affected file lib/silcclient/command.c.
860 * Changed PING to not accept any arguments. The specs
861 says that client can ping only the connected server so
862 requiring an argument is not needed. Affected file is
863 lib/silcclient/command.c.
865 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Fixed a fatal bug in private message sending and reception
868 encryption and decryption when using private message keys.
869 The implementation was incorrect and did not follow the
870 specification. It causd that some of the message were
871 lost since it did not use the sending and receiving keys
872 as the protocol suggests. This has been fixed and will cause
873 incompatibilities with older clients when sending private
874 message encrypted with private message keys. Affected files
875 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
876 and various other in Irssi SILC Client.
878 Added `responder' boolean argument to the functions
879 silc_client_add_private_message_key[_ske] to indicate when
880 the key is added as responder or initiator of the key
883 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Removed the silc_ske_check_version function and created
886 a SilcSKECheckVersion callback. Added also a function
887 silc_ske_set_callbacks that is now used to set all SKE
888 callbacks. The callback functions are not given to
889 the SKE functions anymore, but this function is used to
892 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
894 * Added `silc_version' argument to the silc_client_alloc
895 to define the version of the application for the library.
896 The library will use the version string to compare it
897 against the remote host's (usually a server) version
898 string. Affected file lib/silcclient/silcapi.h
900 * Added the KE protocol context to Key Agreement context
901 in client library so that we can abort the SKE if it
902 is in process when we get timeout. Affected file is
903 lib/silcclient/client_keyagr.c.
905 * Do not resolve the client ID forever if it returns in the
906 first time that such client does not exist. This was done
907 for example with private message. Affected file is
908 lib/silcclient/client_prvmsg.c.
910 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Do not add regex.h for WIN32. The affected file
913 includes/silcincludes.h.
915 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
916 not work yet 100%. It generates the DLL's automatically
917 when compiling with --with-win32 under cygwin.
919 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
921 * lib/contrib/regex.c is not compiled on WIN32.
923 * Added silc_net_get_socket_opt function to the
924 lib/silcutil/silcnet.h.
926 * Added includes/silcwin32.h for WIN32 specific includes
929 * Do not use ptime structure or any of the posix process
930 functions on WIN32 in lib/silccrypt/silrng.c.
932 * Added silc_gettimeofday to provide generic function
933 for struct timeval on all platforms. Added the function
934 to lib/silcutil/silcutil.h.
936 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Moved the lib/silccore/silcsockconn.[ch] to the utility
939 library as they clearly belong there. As a plus side we
940 can make the actual socket connection routines platform
943 Added also new generic function silc_socket_read and
944 silc_socket_write (that used to be silc_packet_[read/write].
945 The implementation of these are platform specific.
947 * Added WIN32 specific routines of silc_socket_[read/write]
948 to lib/silcutil/win32/silcwin32sockconn.c.
950 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Added preliminary support for native WIN32 compilation under
953 cygwin (using the -mno-cygwin option for GCC) to the
954 ./configure.in.pre. The --with-win32 now prepares the
955 compilation for native WIN32.
957 * Rewrote the SILC Scheduler interface in the file
958 lib/silcutil/silcschedule.h. The scheduler is now context
959 based and does not have anymore any global static scheduler.
960 Moved the Unix scheduler to the lib/silcutil/unix/ directory
961 and created lib/silcutil/win32 directory for WIN32 based
964 * Added Unix specific network routines to the
965 lib/silcutil/unix/silcunixnet.c and the old
966 lib/silcutil/silcnet.c includes now only generic routines.
968 Added WIN32 specific network routines to the
969 lib/silcutil/win32/silcwin32net.c.
971 * Added Unix specific utility functions from the
972 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
974 * Added WIN32 SILC Scheduler to the file
975 lib/silcutil/win32/silcwin32schedule.c. The code is of course
978 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
980 * Do not handle JOIN notify in the server if the target client
981 is not registered (idata->registered == FALSE). The affected
982 file is silcd/packet_receive.c.
984 * Update the nickrec->founder in event_cumode in the Irssi SILC
985 client. Affected file irssi/src/silc/core/silc-channels.c.
987 * Fixed the CUMODE_CHANGE notify handling in the server when
988 server and router are announcing their clients on channels.
989 Now the mode changes are saved and notified correctly. The
990 affected file is /silcd/packet_receive.c.
992 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
993 They really did not replace the cache entry in the ID Cache.
994 Now they do that. Affected file silcd/idlist.c.
996 * Fixed the KICK notify handling in the Irssi SILC client to
997 update the channel records so that the kicked client does not
998 appear to be on the channel. The affected file is
999 irssi/src/silc/core/silc-channels.c.
1001 * Always update the conn->current_channel when executing command
1002 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1004 * Fixed the KILL notify handling in Irssi SILC client to remove
1005 the killed client on all channels.
1007 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Fixed the silc_parse_command_line to remove extra spaces
1010 from the start and end of the arguments. Affected file is
1011 lib/silcutil/silcutil.c.
1013 * Cancel and free any active protocol in the function
1014 silc_server_close_connection. Affected file silcd/server.c.
1016 * Cancel and free any active protocol in the function
1017 silc_client_close_connction. Affected file is
1018 lib/silcclient/client.c.
1020 * Do not execute the KILL command for clients that are in
1021 history (ie. they are not in the network). Affected file is
1024 * Fixed KILL notify handling, client does not crash anymore.
1025 Affected file irssi/src/silc/core/silc-channels.c.
1027 * Reduced the default packet buffer size from 2048 to 1024 in
1028 lib/silccore/silcpacket.c.
1030 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1031 counter to the SKE context that is incresed when the SKE library
1032 performs async operation outside the library. If the outside
1033 process frees the SKE context and FREED status will be set
1034 and the library will detect after the sync operation that the
1035 libary is freed. The affected files are
1036 lib/silcske/silcske[_status].[ch].
1038 * Resolve the client entry information in the function
1039 silc_client_channel_message to assure that NULL pointer is not
1040 passed as client entry to the application. */
1042 * Fixed the task timeout calculation to assure that there is
1043 never negative timeouts. The affected file is
1044 lib/silcutil/silcschedule.c.
1046 * Fixed the channel user mode notification sending in server.
1047 It was sent point-to-point to the router (or to server by router)
1048 but it needs to be destined to a channel. The routines now
1049 supports sending the channel user mode notifys to the channels
1050 when announcing clients and channels. Affected files are
1051 silcd/server.c and silcd/packet_receive.c.
1053 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1054 It did not actually replace the old channel entry in the cache.
1055 Affected file lib/silcclient/client_notify.c.
1057 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Fixed a possible crash in silc_packet_send_prepare. It now
1060 assures always that there is enough space in the buffer and
1061 at the tail area of the buffer (for MAC).
1063 Fixed the inbound buffer reallocation in silc_packet_read.
1064 It was old code and did not handle the reallocation correctly.
1067 The affected file is lib/silccore/silcpacket.c.
1069 * Fixed buffer overflow in silc_parse_nickname in the file
1070 lib/silcutil/silcutil.c.
1072 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * make install generates new server keys only if there is not
1077 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1080 Added check that if the NOREPLY is set then we will not send
1081 the away message. This avoids infinite loop of away messages
1082 if both clients are away. The affected file is
1083 lib/silcclient/client_prvmsg.c.
1085 * Fixed client crash if /NICK was given without arguments.
1086 Affected file lib/silcclient/command.c.
1088 * Server does not send the invite list in INVITE command back
1089 to the client if the list was not altered. Added this notion
1090 to the protocol spec as well. Affected file silcd/command.c.
1092 Fixed possible crash in INVITE command by checking the
1093 value of silc_server_get_client_route command.
1095 * Fixed the INVITE notify type handling. The arguments are now
1096 taken in correct order and client does not crash. The affected
1097 file is irssi/src/silc/core/silc-channels.c.
1099 Removed the "Inviting xxx to channel" message from the
1100 client library away and let the application handle it.
1101 Affected file lib/silcclient/command.c. Added that message
1102 to Irssi SILC client's message formats.
1104 * Fixed CMODE command crash in client. It now checks the
1105 amount of arguments correctly and does not crash. The affected
1106 file is lib/silcclient/command.c.
1108 * Do not create new channel automatically in silc_channels_join
1109 but check whether the channel by that name already exists.
1110 Affected file irssi/silc/core/silc-channels.c.
1112 * Do not send the SERVER_SIGNOFF to router if the disconnected
1113 entity was the router. Affected file silcd/server.c.
1115 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1116 SILC client as it was missing from there.
1118 Added the handling of the KICK notify to the Irssi SILC client
1119 as it was missing. Added "you have been kicked" message to
1120 Irssi SILC client's message modules formats.
1122 Added the handing of the KILL notify to the Irssi SILC client
1123 as it was missing. Added the kill message module formats
1126 The affected file is irssi/src/silc/core/silc-channels.c.
1128 * The router did not save the channel mode the server announced.
1129 Affected file silcd/packet_receive.c.
1131 * Fixed a possible crash in INFO command in server. If the
1132 server did not provide the server info it crashed. Affected
1133 file silcd/command.c.
1135 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Fixed the GETKEY command in the server to check also the
1138 global list. Otherwise the GETKEY would not work correctly
1139 in normal SILC server. Affected file silcd/command.c.
1141 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Fixed GETKEY crash, it crashed if the command did not succseed.
1145 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1148 is now real and not just an macro interface to GMP.
1150 Removed the entire GMP from the source tree and imported new
1151 NSS MPI library instead. Reason for removing GMP is that it is
1152 extremely large and compiles extremely slow. The NSS MPI
1153 is only a few files and compiles in less than 10 seconds.
1154 The speed is also about the same as GMP. The MPI is imported
1155 to lib/silcmath/mpi.
1157 If the system has GMP installed we will still use the GMP.
1158 If it is not then the NSS MPI will be compiled.
1160 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Merged a long nickname (127 characters long) crash bugfix from
1163 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1165 * Merged a freed memory reference bugfix from Irssi CVS tree.
1166 Affected file irssi/src/core/commands.c.
1168 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Added the server's public key sving and verification to the
1171 server when performing the SKE. This was missing and the
1172 remote server's (or router's) public key was accepted without
1173 checking whether we have it previously or trust it at all.
1174 Affected file silcd/protocol.c.
1176 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Check in the silc_server_timeout_remote if protocol is active
1179 and make sure that the protocol's final callback is called so
1180 that all memory if freed. Affected file silcd/server.c.
1182 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * silc_server_whois_send_reply crashed the server if the nickname
1185 was 127 characters long. Affected file silcd/command.c.
1187 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1189 * Added sanity check to the silc_server_new_client. If the hostname
1190 is provided inside username then check that the provided hostname
1191 really is the same as the resolved one. If the hostname was not
1192 resolved then check it from the public key. Affected file is
1193 silcd/packet_receive.c.
1195 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1196 if the server disconnected us and the connection is not valid
1197 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1199 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1200 the library to the lib/silcutil/silcutil.[ch].
1202 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Close log file after open. Affected file
1205 lib/silcutil/silclog.c.
1207 * Check whether sock == NULL in silc_client_send_packet and return
1208 if it is. Affected file lib/silcclient/silcclient.c.
1210 * Check rec->entry == NULL in the Irssi SILC Client before
1211 sending the channel message. Affecte file is
1212 irssi/src/silc/core/silc-servers.c.
1214 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1216 * Merged a splitted window bugfix from Irssi CVS tree. The
1217 affected file is irssi/src/fe-text/textbuffer-view.c.
1219 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1220 It did not print nickname.
1222 * Improved the distributions system a bit.
1224 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1227 irssi/src/fe-text/gui-window.c.
1229 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1230 to in-active server. The affected file is
1231 irssi/src/silc/core/client_ops.c.
1233 * Resolve the client in USERS command reply if the entry does
1234 not have username resolved. The affected file is
1235 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1236 command to WHOIS command to really resolve stuff. The USERS
1237 is not used any more in any critical section so WHOIS can
1238 be used even though it might be slower than IDENTIFY.
1240 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1243 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Changed the protocol API a bit more consistent in the
1246 lib/silccore/silcprotocol.[ch].
1248 * Changed the following headers to ROBODoc format:
1250 lib/silccore/silcpayload.h
1251 lib/silccore/silcprotocol.h
1252 lib/silccore/silcsockconn.h
1254 All core library headers are now formatted.
1256 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Fixed a bug in Irssi SILC client; do not show that you are
1259 server/router operator if you really are not. Affected file is
1260 irssi/src/silc/core/client_ops.c.
1262 * Renamed silc_command_free_payload to silc_command_payload_free.
1263 Affected file lib/silccore/silccommand.h
1265 * Added silcmath.h to include the prototoypes of various routines
1266 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1269 * Changed the following headers to ROBODoc format:
1271 lib/silccore/silcchannel.h
1272 lib/silccore/silccommand.h
1273 lib/silccore/silcid.h
1274 lib/silccore/silcidcache.h
1275 lib/silccore/silcmode.h
1276 lib/silccore/silcnotify.h
1277 lib/silccore/silcpacket.h
1278 lib/silcmath/silcmath.h
1280 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Added checking to the server code not to start the server if
1283 ciphers and stuff are not configured properly. Affected files
1284 silcd/serverconfig.[h] and silcd/server.c.
1286 * Changed the layout of the header files of the public interfaces
1287 in the SILC libraries. The new layout supports ROBODoc
1288 documentation tool (and some others) so that it is easy to create
1289 a library reference manual. All the other headers and source
1290 code must still follow the CodingStyle document. Also source
1291 code must not include these ROBODoc stuffs, only the headers.
1292 Furthermore, all public interface headers must now be named
1293 by using `silc' prefix, example: silcapi.h, silccipher.h.
1294 Some files were renamed due to this. All the other headers
1295 must not be used as public interfaces. I will update the
1296 CodingStyle document later. Changed following headers, so far:
1298 lib/silcclient/silcapi.h
1299 lib/silccore/silcauth.h
1300 lib/silccore/silcprivate.h
1301 lib/silccrypt/silcdh.h
1303 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Removed silc_client_packet_send_flush from the client library
1308 as it is not needed. Affected file lib/silcclient/client.[ch].
1310 * Added printing of message of unresolved authentication method
1311 to the Irssi SILC client. Added it to the module formats.
1312 Removed the same message from the client library.
1314 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * Added new distribution feature, DISTLABEL. Every distribution
1317 can define own preprocessor label that can be used in the
1318 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1319 file distributions, acconfig.h.pre and prepare.
1321 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Added Makefile.defines_int to include the actual definitions
1324 for Makefile.defines.in. Tested the new distribution system,
1325 created distributions and tested installation.
1327 * Added AWAY message printing to the Irssi SILC client. Added
1328 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1330 * Added SCONNECT command to call the SILC's CONNECT command.
1331 Cannot use CONNECT directly since Irssi uses that internally.
1332 Affected file irssi/src/silc/core/silc-servers.c.
1334 Added ACTION local command. It is same as ME command but takes
1335 the channel as mandatory argument.
1337 Rewrote some of the Irssi's help files to suite for SILC
1340 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Added Makefile.defines[.in] that should for now on be included
1343 in all Makefile.am file in the source tree. That file includes
1344 all common compilation definitions for SILC source tree.
1346 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * Minor changes to the ./prepare script to change the package
1349 name according the distribution name to the configure.in.
1351 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Created new distribution system. Added file `distributions'
1354 that defines all the distributions that can be created out of
1355 the SILC source tree. The ./prepare script now reads that
1356 file to determine how to prepare the distributions. The
1357 first argument to the ./prepare is the name of the distribution
1358 and second is the version of the distribution. If given
1359 without arguments it creates the default (toolkit) distribution
1360 with the default version (defined in ./prepare).
1362 All Makefile.am files that are subject to the distributions
1363 are now named as Makefile.am.pre. These are ./Makefile.am
1364 and lib/Makefile.am. Others may be changed later.
1366 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Added invite list, ban list, some key management and connection
1369 error message printing to module formats in the Irssi SILC client.
1371 * Added new silc_client_set_away_message to set the away message
1372 that is back to the person who sent private message. The
1373 affected file lib/silcclient/silcapi.h and the
1374 lib/silcclient/client_prvmsg.c.
1376 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Fixed the private message sending in the Irssi SILC client,
1379 added local command KEY to the Irssi SILC client.
1381 Added key management and key agreement message formats to the
1382 irssi/src/fe-common/silc/module-formats.[ch].
1384 Added USERS (alias WHO) printing, server/router operator
1385 indication and LIST command printing to the module formats.
1387 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Fixed channel joining notify handling, cumode notify handling
1390 from Irssi SILC client.
1392 * Added SILC specific module-formats to the Irssi SILC client so
1393 that SILC specific message hilighting, colors etc is possible.
1394 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1396 Added channel mode, channel user mode, actions, notices,
1397 whois and whowas printing to the the module-formats.c.
1399 * Fixed a bug in channel deletion in the server. The channel
1400 is not left to the cache even if the channel founder auth mode
1401 is set when there are no users anymore on the channel. Affected
1402 file silcd/server.c.
1404 * The silc_net_localhost now resolves the entire hostname including
1405 the domain name. Affected file lib/silcutil/silcnet.c.
1407 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Changed the ask_passphrase client operation to be ascynchronous.
1410 It has now a completion callback and a context that the
1411 application must call after it has got the passphrase from
1412 the user. Affected files lib/silcclient/silcapi.h,
1413 lib/silcclient/protocol.c, lib/silcclient/command.c and
1416 Added SilcAskPassphrase callback that the application calls
1417 to deliver the passphrase to the library.
1419 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1420 The public key verification and especially a certificate
1421 verification is asynchronous procedure.
1423 Added new SILC_SKE_STATUS_PENDING status to indicate the
1424 request is pending and a callback will be called to finalize
1427 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1428 indicate that remote end did not send its public key (or
1429 certificate), even though we require it. Added check for this
1430 condition in the SKE. This was a security bug, now fixed.
1432 Defined new SilcSKEVerifyCbCompletion callback that is called
1433 when the verification process is completed.
1435 The affected files lib/silcske/silcske_status.h and
1436 lib/silcske/silcske.[ch].
1438 * Changed the verify_public_key client operation to be async
1439 as well. Defined SilcVerifyPublicKey callback that is used to
1440 indicate the success of the public key verification process.
1442 Changed the server and client to use the new async client
1445 * Changed the Irssi SILC client's internal scheduler to be called
1446 twice as many times as it used to be. As a result the client
1447 should be a bit faster now. Affected file is
1448 irssi/src/silc/core/silc-core.c.
1450 * Added support to Irssi SILC client of asynchronous public key
1451 verification and passphrase inquiry. Affected file is
1452 irssi/src/silc/core/silc-core.c.
1454 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1456 * Do not say "You have left channel %s" in client library.
1457 Moved it to the application. Affected files are
1458 lib/silcclient/command.c and silc/client_ops.c.
1460 * Fixed silc_client_get_clients. Command context was not
1461 duplicated and was freed memory in the callback. Affected
1462 file lib/silcclient/idlist.c.
1464 * Do not say "you are now talking..." on JOIN command in the
1465 client library. The appliation must handle it.
1467 * Do not say ".. changed topic to" in command reply in the
1468 client libary. The application must handle it.
1470 * Fixed TOPIC command sending in the client library.
1472 * Fixed a memory leak in silc_client_command_free in the file
1473 lib/silcclient/command.c.
1475 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Imported a modified version of Irssi client to the source tree.
1478 The Irssi will be used to create a new client called
1479 Irssi SILC. Imported to irssi/.
1481 Added silc_core_init_finish function to the Irssi. Affected
1482 file irssi/configure.in.
1484 A lot changes in the Makefile.ams around the irssi tree.
1486 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Do not rehash if the new size is same as the old size of the
1489 hash table, in the silc_hash_table_rehash*. The affected file
1490 lib/silcutil/silchashtable.c.
1492 * Replaced hash_table_del_by_context calls from the server
1493 (when channel->user_list and client->channels) to the
1494 hash_table_del as it is sufficient and faster.
1496 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * Added silc_hash_table_list, silc_hash_table_get and the
1499 SilcHashTableList structure to provide an alternative way to
1500 traverse the hash table. The affected files are
1501 lib/silcutil/silchashtable.[ch].
1503 * Changed the server's idlist routines to use the hash table
1504 routines to optimize the code.
1506 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Replaced the client entry's `channel' list and channel entry's
1509 `user_list' list to hash tables for optimized lookup. Changed
1510 the code to use the hash table interface around the code.
1511 Affected file lib/silcd/idlist.[ch].
1513 * Added `auto_rehash' boolean argument to the function
1514 silc_hash_table_alloc to indicate whether the hash table should
1515 auto-rehash when it thinks is appropriate time. It will
1516 increase the hash table size if the there is twice as much
1517 entries in the table than the size of the table, and will
1518 decrease the size if there are twice as less entries than
1519 the size of the table.
1521 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1525 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * silc_idcache_purge_by_context deletes the entry now by context
1528 as it is supposed to do. Affected file lib/silccore/idcache.c.
1530 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1531 client is not anymore valid (WHOWAS givens the info) and not
1532 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1534 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1536 * Removed the `data' and `data_len' arguments from the ID Cache
1537 interfaces and added `name' argument. ID Cache does not handle
1538 anymore the binary data only a names associated with given ID.
1540 * When hashing a Client ID with silc_hash_id the entire ID is
1541 not hashed anymore, instead only the hash of the Client ID is
1542 hashed. This way we can access the Client ID from the cache
1543 with Client ID but with the hash of the ID (which is a hash of
1544 the nickname) as well without any difference in performance.
1546 Added also silc_idcache_find_by_id_one_ext to do one on one
1547 searching when we have the actual ID. Added also function
1548 silc_hash_client_id_compare. The affected files are
1549 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1551 * When hashing the name associated with a ID it is always done
1552 in lowercase. This way we can access the cache without worrying
1553 about case-sensitivity, even though, for example nicknames are
1556 * Fixed a bug in server with channel message sending. It put
1557 wrong ID type as destination ID. The affected file
1558 silcd/packet_send.c.
1560 * silc_idcache_del_by_context now deletes from all hash tables
1561 by context. Affected file lib/silccore/idcache.c.
1563 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Changed the client library to use the new ID Cache interface.
1566 Changes around the source tree.
1568 * Added silc_hash_table_rehash_ext to rehash with specific
1569 hash function. Affected file lib/silcutil/silchashtable.[ch].
1571 * Added silc_hash_string_compare to compare two strings in the
1572 hash table. Affected file lib/silcutil/silcutil.[ch].
1574 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Added new function silc_idcache_del_by_context into the
1577 lib/silccore/idcache.[ch].
1579 * Changed the server's ID list routines to use the new ID Cache
1580 interface. Changes around the source tree.
1582 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * Added silc_hash_table_del[_by_context]_ext functions in to the
1585 lib/silcutil/silchashtable.[ch].
1587 Removed silc_hash_table_find_all* routines and added new
1588 silc_hash_table_find_foreach to replace them.
1590 Added silc_hash_table_replace_ext function as extended
1591 replacing function. Separated the simple hash table interface
1592 from the extended hash table interface in the file
1593 lib/silcutil/silchashtable.h.
1595 * Fixed minor bugs and changed it to use some of the new
1596 hash table functions in lib/silccore/idcache.c
1598 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Added new function silc_hash_table_find_all to return all keys
1601 in the hash table by the specified key. As the hash table is
1602 collision resistant it also makes it possible to have several
1603 duplicate keys in the hash table. This function may be used to
1604 find all of the keys from the hash.
1606 Added user_context arguments to the SilcHashFunction,
1607 SilcHashCompare and SilcHashDestructor to deliver user specified
1610 Added new fuctions silc_hash_table_find[_all]_ext to do
1611 extended lookup with specified hash and compare functions and
1612 specified user contexts.
1614 Added new function silc_hash_table_add_ext to add the key
1615 with specified hash function and user context.
1617 Added new function silc_hash_table_foreach to traverse all
1618 entrys in the hash table. Added SilcHashForeach callback
1621 Added new function silc_hash_table_del_by_context to delete
1622 the entry only if the context associated with the key matches.
1624 Affected files are lib/silcutil/silchashtable.[ch].
1626 * Removed silc_hash_[server/client/channel]_id and added just
1627 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1628 silc_hash_id_compare to compare two ID's using as the hash table
1629 comparison function. Added also silc_hash_data to hash
1630 binary data and silc_hash_data_compare to compare it.
1632 * Removed silc_idlist_find_client_by_hash as it is not needed
1633 anymore. Affected file silcd/idlist.[ch].
1635 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1636 to use internally the SilcHashTable. The new ID Cache is a lot
1637 faster than the old one. Some of the ID Cache interface was also
1638 rewritten and obsolete and stupid functions were removed.
1640 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Added entry_count field to the SilcHashTable to keep the number
1643 of the entries in the table. Implemented the function
1644 silc_hash_table_rehash. Added new function
1645 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1647 Fixed a minor bug in silc_hash_table_free.
1649 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1650 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1651 into the lib/silcutil/silcutil.[ch].
1653 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Implemented a collision resistant hash table into the
1656 lib/silcutil/silchashtable[ch]. See the header and the source
1657 for the SilcHashTable API.
1659 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1661 * Merged dotconf version 1.0.2 into lib/dotconf.
1663 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Do not compile anything in lib/silcsim/* if the SIM support
1666 is not enabled. The tree should now compile without problems
1669 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * Compiled the SILC under cygwin. Compiled and tested briefly
1672 without problems. More tests needed. The SIMs didn't compile
1675 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1677 * Fixed possible crash in silc_get_username in the
1678 lib/silcutil/silcutil.c.
1680 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Fixed a va_arg in silc/client_ops.c.
1684 * Oops, RC5 routines were named AES and caused some problems
1685 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1687 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Added new SilcIDIP structure into the lib/silccore/id.h and
1690 replaced the old `ip' fields from all SILC ID's to that type.
1691 This is a step towards IPv6 support.
1693 The silc_id_get_len takes now the ID as an extra argument.
1694 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1695 both IPv4 and IPv6 based ID's.
1697 The affected files are lib/silccore/id.[ch] and other files
1698 around the tree using these routines.
1700 * Removed the ID length arguments in server from various
1701 silc_server_send_notify_* routines -> they are not needed
1704 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Fixed memory leak in silc_encode_pem_file in the file
1707 lib/silcutil/silcutil.c.
1709 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1711 * Check minor version as well in the SKE. Affected files are
1712 silcd/protocol.c and lib/silcclient/protocol.c.
1714 * Added --identifier option to the server so that an identifier
1715 can be when creating the public key for the server. Affected
1716 file is silcd/silcd.c.
1718 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1719 lib/silccrypt/silcpkcs.c.
1721 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1723 * Register default ciphers and stuff when using -C option with
1724 the server. Affected file sildc/silcd.c.
1726 * Put back the servers public key filename format, it is better
1727 than the new one. For now, the client keys are saved with the
1728 new filename format. The affected file silc/client_ops.c.
1730 * Implemented the Cipher API for the rest of the ciphers that
1731 did not implement it or implemented it the wrong way.
1733 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Register default ciphers and stuff when using the -S option
1736 in the client. Affected file silc/silc.c. Same also when
1737 creating new key pair with -C option.
1739 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Fixed the silc_verify_public_key client operation function to
1742 save the public keys differently. The fingerprint is now
1743 used as filename and not the hostname. This way also the
1744 client keys are saved uniquely and not with hostnames. The
1745 affected file is silc/client_ops.c.
1747 * Trimmed the silc_hash_fingerprint function to remove extra
1748 whitespaces from the end of the fingerprint. The affected
1749 file is lib/silccrypt/silchash.c.
1753 * Added silc_cipher_register_default function to register all
1754 default ciphers. It can be used when configuration files
1755 does not exist and the application does not want any specific
1756 ciphers in any specific order.
1758 The SilcDList is now used as silc_cipher_list dynamically
1759 allocated cipher list. Removed the static list all together
1760 and now all ciphers must be allocated to the dynamic list.
1761 The silc_cipher_alloc routine was changed to check only the
1764 All silc_cipher_* routines that used to return int returns
1767 The affected files lib/silccrypt/silccrypt.[ch].
1769 * The same thing was done to silc_hash_* as for silc_cipher_*
1770 routines. Affected files lib/silccrypt/silchash.[ch].
1772 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1773 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1774 Added also silc_pkcs_[un]register[_default] functions.
1775 Removed the data_context from the PKCS API.
1777 * Added silc_hmac_register_default function to register default
1778 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1779 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1780 to unregister all hmacs at once.
1782 * Register the default ciphers, hash functions, PKCSs and HMACs
1783 if client's configuration file does not exist. The affected
1786 * The client did not load the hash functions from the SIM
1787 modules at all. Added support for this. Affected file is
1788 silc/clientconfig.c.
1790 * When decoding public key with silc_pkcs_public_key_decode, check
1791 the supported algorithm only if PKCS are registered. Affected
1792 file lib/silccrypt/silcpkcs.c. The same was done with the
1793 silc_pkcs_private_key_decode.
1795 * Fixed the SILC List routines to keep the list always in order.
1796 It used to change the list's order when traversing the list but
1797 not it preserves the order. Affected file lib/trq/silclist.h.
1799 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * Added the client library to use the SilcSocketConnection's
1802 reference counter (by silc_socket_dup) to prevent the bug that
1803 the socket object may be freed underneath async operation.
1805 * The name resolv library checking fixes in the configure.in.pre.
1808 * Created new version of the protocol drafts for future
1809 development. The -03 drafts are the ones that will be changed
1810 in the trunk now and the -02 will remain as they are.
1812 * Send list of CUMODE notifys to the router when announcing
1813 the channel users to the router. Affected file silcd/server.c.
1814 If the router receiving channel founder CUMODE for a channel
1815 that already has channel founder it will send CUMODE notify
1816 to the sender to remove the channel founder rights from the
1817 announced client. Affected file silcd/packet_receive.c.
1819 * The CUMODE notify may now use Server ID as well as the entity
1820 who changes the mode. Updated protocool specs.
1822 * Updated INSTALL and README files.
1824 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1826 * New web pages in the http://silc.pspt.fi. The pages was
1831 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Implemented the [DenyConnectin] config section in the server.
1834 Added silc_server_config_denied_conn to check whether incoming
1835 connection is denied. Affected file silcd/serverconfig.[ch].
1837 * Do not check the ports when checking the incoming configuration
1838 data if the port is 0, meaning any. Affected file is
1839 silcd/serverconfig.c.
1841 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Fixed buffer overflow in silc_string_compare in the file
1844 lib/silcutil/silcutil.c.
1846 * Fixed double free in silc_server_command_leave in the file
1849 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Fixed the version checking in the server. Affected file is
1854 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Fixed the configuration data fetching when accepting new
1857 connections in the server. Affected file silcd/server.c.
1859 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Added `sender_entry' argument to the function
1862 silc_server_packet_relay_to_channel so that we can check
1863 whether some destination actually belongs to the same route
1864 the sender belongs (ie, we must not resend the packet to the
1865 sender). Affected file silcd/packet_send.[ch].
1867 * Added `servername' field to the SilcClientEntry in the server
1868 to hold the name of the server where client is from. Affected
1869 file is silcd/idlist.h.
1871 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Moved the channel message encrypting in the router betwen
1874 router connections from silc_server_channel_message to the
1875 silc_server_packet_relay_to_channel since we want to check
1876 whether we have anybody channel before encrypting anything.
1877 Affected files silcd/packet_[receive/send].c.
1879 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1881 * Fixed the [AdminConnection] server config section to support
1882 multiple entries. Affected file silcd/serverconfig.c.
1884 * Added support into the server to check the validity of the
1885 incoming connection before executing any KE or authentication
1888 * The connection configuration is now saved to the KE and
1889 connection auth protocol contexts and not fetched anymore in
1890 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1892 * The local hosts listenning address and port is also resolved
1893 now when starting the server. We want to have the socket object
1894 to include the real address and port for the listener. Added
1895 new function silc_net_check_local_by_sock into the files
1896 lib/silcutil/silcnet.[ch].
1898 * Fixed a broadcast bug in server -> do not broadcast if we
1901 * Fixed a routing bug. Do not route broadcast packets ever.
1902 Broadcast packets must be processed always and not routed since
1903 they may be destined to some other host than yourself and thus
1904 would get routed without no good reason. Affected file is
1907 * Added function silc_server_config_is_primary_route to check
1908 whether primary router connection has been configured (a router
1909 configuration that we are initiating). If there is not, we
1910 will assume that there is only two routers in the SILC network
1911 and we will use the incoming router connection as our primary
1912 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1914 * Changed the order of the broadcasting. Broadcast _after_ the
1915 packet has been processed not before. Affected file is
1918 * Fixed a [ClientConnection] parsing bug. The port was never
1919 parsed correctly thus resulting to port 0. Affected file
1920 silcd/serverconfig.c.
1922 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1923 argument and did not set the broadcast packet flag. Affected
1924 file silcd/packet_send.c. Fixed same bug in the function
1925 silc_server_send_notify as well.
1927 * If we receive NEW_ID packet for our own ID in the server, ignore
1930 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1934 * Removed the nickname from the Private Message Payload.
1935 Updated the code and the protocol specs.
1937 * Updated protocol specs for submitting to the IETF.
1939 * Tweaked the Random Number Generator a bit. Affected file
1940 lib/silccrypt/silcrng.c. Exported a new function
1941 silc_rng_[global]_add_noise which can be used to add more
1944 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Do not parse packets with different timeout when protocol
1947 is active -> may cause problem with rekey. Affected file
1950 * When server receives signoff notify it must not create
1951 new channel key if the client is on any channels since the
1952 sender of the signoff notify will create it.
1954 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1956 * Added printing of error messages during SKE protocol from the
1957 failure packet sent by server during SKE. Affected file
1960 * Removed the client's failure_callback handling with timeout
1961 and handle it immediately when received.
1963 * The SKE library returned wrong type in SUCCESS and FAILURE
1964 packets. They must be 32 bit MSB not 16 bit MSB.
1966 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Ok, rewrote the logic of the re-key and now it seems to work.
1969 I tested it on high traffic with frequent re-keys without
1970 problems. Added hmac_receive (and renamed hmac to hmac_send)
1971 in SilcClientConnection in lib/silcclient/client.h and
1972 in SilcIDListData in silcd/idlist.h. Also, removed the
1973 SilcPacketParserContext's cipher and hmac fields as they are
1974 not needed anymore and actually caused some problems when
1975 the ciphers and hmac's changed underneath the packet parser.
1977 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * If re-key protocol is active then process the incoming packets
1980 synchronously since we must assure that icoming packets encrypted
1981 with the old key is processed before the new keys is set to
1982 use. This is true other packets than for REKEY packets.
1983 Affected file silcd/server.c. The same was done to client library
1984 as well, affected file lib/silcclient/client.c.
1986 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Fixed bug in client and server to accept the force send if
1989 the packet is send from silc_[server/client]_packet_process
1990 function. Otherwise the packets are never delivered, oops.
1992 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Disable force sending of packets when REKEY protocol is active.
1995 We must assure that no packet is sent directly when rekey is
1996 performed. All packets must be sent through packet queue.
1997 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1998 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1999 function is silc_[server/client]_packet_send_real to check
2002 * Replaced the SIM paths from example config files to
2003 /usr/local/modules. Also, make install creates now
2004 /usr/local/silc/logs directory to hold all the SILC server
2007 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Made the configure.in.pre work on Solaris. Patch by salo.

2012 CBC mode macros into lib/silccrypt/ciphers_def.h.
2014 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Fixed the make install.
2018 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * When MAC computation fails the silc_packet_decrypt returned 0
2021 even though it was supposed to return -1. Fixed this. The
2022 affected file is lib/silccore/silcpacket.c.
2024 * Do not replace the config files in /etc/silc (in make install)
2025 if they already exist. Affected file ./Makefile.am.
2027 * Do not send re-key packets immediately but through packet queue.
2028 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2030 * Changed silc_net_check_host_by_sock to return FALSE if the
2031 IP/DNS could not be resolved. Though, it returns the IP address
2032 now even if it could not resolve it (but returns also FALSE).
2033 Affected file lib/silcutil/silcnet.[ch].
2035 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Added silc_pkcs_decode_identifier to decode the public key's
2038 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2039 Added also silc_pkcs_free_identifier. Added also new context
2040 SilcPublicKeyIdentifier.
2042 * Added -S option to the silc client. It is used to dump the
2043 contents of the specified public key file.
2045 * Changed the PKCS api to return the public key length when
2046 setting the public key.
2048 * Fixed a fatal bug in the public and private key file loading.
2049 Affected file lib/silccrypt/silcpkcs.c.
2051 * Execute the packet parsing for client with zero (0) timeout
2052 if the protocol is active. Affected file silcd/server.c.
2054 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Made the key generation options to the silcd program. Added
2057 -C option, equivalent to client's option.
2059 * Added new [ServerKeys] config section to the server. It
2060 configures the server's public and private key.
2062 * Defined generic Public Key Payload into the protocol
2063 specification to send specific type of public keys and
2066 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2067 public key or certificate.
2069 * Implemented the GETKEY command to the server and to the
2070 client library and on user interface.
2072 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2074 * Made preliminary `make install' work.

2103 SilcClientConnection structure; not needed. Affected file is
2104 lib/silcclient/client.h.
2108 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2110 * Do not ask whether user wants to use the negotiated private key
2111 for private messages, just use it. Affected file is
2112 silc/local_command.c.
2114 * Added `send_enc_key' and `enc_key_len' fields to the
2115 SilcIDListData structure since they are needed in the re-key

2139 * Changed _ALL_ unsigned long and unsigned int to uint32,
2140 unsgined short to uint16 in the source tree.
2142 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2143 not handle clients that has entry->data.registered == FALSE.
2144 They are not in the network anymore. Affected file is
2147 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2156 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2157 Affected file silcd/packet_receive.c.
2159 * Implemented the SERVER_SIGNOFF notify handling in the client
2160 library. Affected file lib/silcclient/client_notify.c. Also,
2161 implemnted the printing of the SERVER_SIGNOFF info to the
2162 application. Affected file silc/client_ops.c.
2164 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2165 if the deleting was successful. Affected file silcd/idlist.[ch].
2167 * Added support for public key authentication in the connection
2168 authentication protocol in the client library. Affected file
2169 lib/silcclient/protocol.c.
2171 * Changed the server's silc_idlist_get_clients_by_* interface
2172 to support already allocated array so that new entries may be
2173 added to pre-allocated array. Affected file silcd/idlist.[ch].
2174 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2175 and command replies.
2177 * All command reply functions in the server now calls the
2178 pending command callback even if error occured. This way the
2179 error will be delivered to the client as well. Affected files
2180 silcd/command.c and silcd/command_reply.c.
2182 * Fixed INFO command to return local server's info if no server
2183 was provided. Affected file lib/silcclient/command.c.
2185 * Removed RESTART command for good. Updated the code and the
2188 * Rewrote parts of the task system. It is a bit simpler now.
2189 Removed unsued task priorities. The affected files are
2190 lib/silcutil/silctask.[ch].
2192 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Moved the USERS printing from the library to the application.
2195 Affected files lib/silcclient/command.c and silc/client_ops.c.
2197 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * Added channel key re-key support. The re-key is perfomed
2202 only by the router and is done once in an hour. Added `rekey'
2203 field to the SilcChannelEntry in the server. Affected files
2204 silcd/server.c and silcd/idlist.h.
2206 * Added silc_task_unregister_by_context into the file
2207 lib/silcutil/silctask.[ch].
2209 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Added SILC_UMODE_GONE mode to indicate when the client is not
2212 present in the SILC network. Added also support to the local
2213 command AWAY that will set this mode. Added support of showing
2214 "xxx is gone" in WHOIS command. The USERS command shows the
2215 gone status as well.
2217 * Fixed setting server and router operator privileges in the
2218 server's UMODE command. Affected file silcd/command.c.
2220 * Merged the SKE KE1 and KE2 payloads into one payload. The
2221 new KE payload is equivalent to the old KE2 payload.
2223 Cleaned up the SKE Start Payload parsing. It now uses the
2224 simple buffer unformatting to do the parsing. A lot faster
2227 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2228 to the SKE that is used to indicate whether both of the SKE
2229 parties should perform authentication. By default only the
2230 responder performs authentication. By setting this flag also
2231 the initiator must do authentication. By default it is unset
2232 since in normal SKE case, client to server connection, only
2233 the responder should do authentication. When doing SKE between
2234 two clients both should perform authentication. Updated the
2235 code and the protocol specs.
2237 * A little fix to IDENTIFY command in the server. Search the
2238 client first by hash not nickname. Affected file is
2241 * Fixed the silc_client_close_connection to support closing
2242 the client to client connections wihtout deleting too much
2243 data. Affected file lib/silcclient/client.c.
2245 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2246 are received if protocol used to be active but is not anymore
2247 the application would crash due to NULL pointer dereference.
2248 Affected files silcd/server.c and lib/silcclient/client.c.
2250 * Added `hash' field to the SilcClientConnection to include
2251 the hash function negotiated in the SKE protocol.
2253 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2254 to set the channel founder authentication data. A client can
2255 claim the founder rights later by providing the authentication
2256 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2257 This way the channel founder can regain the channel founder
2258 privileges even it is left the channel. This works only on
2259 local server and the client must be connected to the same
2260 server to be able to regain the founder rights. Updated the
2261 protocol specs accordingly.
2263 Added support to the CMODE command in the client to set the
2264 founder auth data. Read the README to see how to set it.
2266 Added support to the CUMODE command to claim the founder
2267 rights. Read the README to see how to do it.
2269 Added support for the founder authentication to the Channel
2270 Entry in the server. Affected file silcd/idlist.h.
2272 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2273 server's CMODE command. Affected file silcd/command.c.
2275 * Added the following new functions into lib/silccore/silcauth.[ch]:
2276 silc_auth_get_method and silc_auth_get_data.
2278 * The server now saves the remote hosts public key to the
2279 SilcIDListData pointer. Affected file silcd/protocol.c.
2281 * The normal server now does not remove the channel entry from
2282 the cache if the founder authentication data is set. It used
2283 to remove it if the founder was the last one on the channel on
2284 the server and left the channel. The auth data is saved and
2285 if the channel is re-joined later the old entry is used with
2286 the old auth data. Affected files silcd/command_reply.c and
2289 * Removed the `pkcs' field from the SilcIDListData structure
2290 in the server; it is not used. Affected file silcd/idlist.h.
2292 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Fixed packet processing on slow links. Partial packets were
2295 never re-processed because the incoming data buffer was cleared
2296 by the application. Application must not directly clear the
2297 sock->inbuf, the packet processing routines handle it. Fixed
2298 this in client library and in server.
2300 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2302 * Fixed the WHOIS and IDENTIFY send reply function to really
2303 check whether to send list or just one entry. Affected file
2306 * Cleaned up the LEAVE command's channel key distribution. The
2307 affected file silcd/command.c.
2309 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2310 can enforce the channel mode as well. In that case the ID
2311 includes the ID of the server. The code now enforces the
2312 mode change if the router have different mode than the server.
2314 * The notify client operation with CMODE_CHANGE notify can now
2315 return NULL client_entry pointer if the CMODE was not changed
2316 by client. Application must check for this.
2318 * Added <Server ID> argument to INFO command to support server
2319 info fetching by Server ID.
2321 * Added silc_server_announce_get_channel_users to get assembled
2322 packets of channel users of the specified channel. Affected
2323 file silcd/server.[ch].
2325 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2326 was freed underneath the ID Cache.
2328 * Re-announce clients when the server received CHANNEL_CHANGE
2329 notify from the router. Affected file silcd/packet_send.c.
2331 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2334 crashed since it did not handle the fact that there is no cipher
2335 called "3" and didn't check the error condition. Now fixed.
2337 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2338 flag. It can be used to send message requests.
2340 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Implemented the RESTART command in the client.
2344 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2345 notice type messages. Added notice printing to the user
2348 * The channel keys are not re-generated if the channel's mode
2349 is PRIVKEY, ie private key on the channel exists. Affected
2350 files silcd/server.c and silcd/command.c.
2352 * Fixed a little bug in channel message delivery when channel
2353 private keys are set in the server. Affected file is
2354 silcd/packet_send.c.
2356 * Changed the setting on channel->on_channel = TRUE from the
2357 silc_client_save_channel_key to the JOIN command reply. The
2358 key payload is not received if the private channel key is set.
2359 Affected file lib/silcclient/command_reply.c and the
2360 lib/silcclient/client_channel.c.
2362 * When the CMODE_CHANGE notify is sent and the channel private
2363 key mode is removed the channel key must be re-generated in
2364 other cells as well. Added this support for the router in the
2365 silcd/packet_receive.c.
2367 * Added new local command NOTICE to send notice message on
2368 channel. Affected file silc/local_command.[ch].
2370 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2372 * Added new local command ME to the client. It is used to send
2373 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2374 some action. Affected file silc/local_command.[ch].
2376 * Changed channel_message and private_message client operations
2377 to deliver the message flags to the application. Added also
2378 the `flags' arguments to the silc_client_send_channel_message
2379 and silc_client_send_private_message functions. Affected file
2382 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Redefined the Private Message Payload to support private message
2385 keys and to support the new private message flags. Updated
2386 the protocol specs. Flags makes it possible to have for example
2387 CTCP style messages.
2389 * Added new type SilcPrivateMessagePayload and defined an API
2390 for it in the lib/silcclient/silcprivate.[ch].
2392 * Tested private message private keys successfully. Tested the
2393 private message key set, unset and list commands with the new
2396 * Redefined the Channel Message Payload to include the channel
2397 message flags (equal with private message flags) to support
2398 for example CTCP style messages.
2400 * Defined some of the message (for channel and private message)
2401 flags. Updated the protocol specs and added the flags to the
2402 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2404 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Added SilcKeyAgreementStatus type to the key agreement routines
2407 to indicate the current status and error if one occured.
2408 The status types are defined in the lib/silcclient/silcapi.h.
2410 * Added new local command KEY that is used to set and unset private
2411 keys for channels, set and unset private keys for private messages
2412 with remote clients and to send key agreement requests and
2413 negotiate the key agreement protocol with remote client. The
2414 key agreement is supported only to negotiate private message keys,
2415 it currently cannot be used to negotiate private keys for channels,
2416 as it is not convenient for that purpose.
2418 * Fixed a minor pending callback setting bug in the function
2419 silc_client_get_client_by_id_resolve, now the function works.
2420 Affected file lib/silcclient/idlist.c.
2422 * Added function silc_net_get_local_port to get local bound
2423 port by socket. Added to lib/silcutil/silcnet.[ch].
2425 * Added `sockets' and `sockets_count' fields to the SilcClient
2426 object. They hold the sockets of the listenning sockets in
2427 the client. Listenning sockets may be for example the key
2428 agreement server. Affected file lib/silcclient/client.[ch].
2429 Added functions the silc_client_add_socket and the
2430 silc_client_del_socket. They are exported to the application
2433 * Added ~./silc/clientkeys to support other client's public keys.
2435 * Renamed verify_server_key client operation to verify_public_key
2436 and added one argument to indicate the type of the connection
2437 (server, client etc.).
2439 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Added silc_server_connection_auth_request to handle the
2442 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2443 silcd/packet_receive.[ch].
2445 * Added silc_server_send_connection_auth_request into the
2446 silcd/packet_send.c to send the connection auth request packet.
2448 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2451 * Fixed the public key authentication in responder side in the
2452 server. The `auth_data' pointer includes the SilcPublicKey
2453 not the path to the public key. Affected file silcd/protocol.c.
2455 * Implemented the public key authentication in the initiator side
2456 in the server. Affected file silcd/protocol.c.
2458 * Removed the [RedirectClient] config section from the server
2459 configuration. Is not needed and I don't want to implement it.
2461 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2463 * Cleaned up the CMODE command in the server. It now works
2464 correctly and supports all the modes defined in the protocol.
2465 Affected file is silcd/command.c.
2467 * Added `hmac_name' field to the SilcChannelEntry in the server
2468 to hold the default HMAC of the channel. It can be set when
2469 creating the channel (with JOIN command). Affected files
2472 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2473 type to indicate the change of the current cipher and hmac
2474 on the channel. Client can safely ignore the <cipher> argument
2475 (if it chooses to do so) since the CHANNEL_KEY packet will
2476 force the channel key change anyway. The <hmac> argument is
2477 important since the client is responsible of setting the new
2478 HMAC and the hmac key into use.
2480 * Fixed the CMODE command in the client library as well.
2482 * Tested CMODE command in router environment successfully.
2484 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Show the version of the remote client (or server) when connecting
2487 to the server. It is logged to the log file. Affected file
2488 is silcd/protocol.c.
2490 * Fixed the KILLED notify handling in the client library. The
2491 client must be removed from all channels when receiving the
2494 Also, do not remove the client entry when giving the KILL
2495 command but when the KILLED notify is received.
2497 * Removed silc_idlist_find_client_by_nickname from the server.
2498 Not needed anymore. Affected files silcd/idlist.[ch].
2500 * Implemented the CHANNEL_CHANGE notify type handling to the
2501 server. Affected file silcd/server.c.
2505 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Added silc_server_send_notify_invite to send the INVITE
2508 notify between routers.
2510 * Implemented the INVITE command correctly to the server.
2512 * Implemented the INVITE notify type handling in the server.
2514 * Implemented the INVITE command to the client library and on the
2517 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Added function silc_server_get_client_resolve to find the
2520 client entry by ID from all ID lists and then resolve it
2521 (using WHOIS) if it cannot be found. Affected file is
2524 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Implemented the BAN command to the client library.
2528 * The JOIN command in the server now checks the invite list
2531 * Changed the silc_command_reply_payload_encode_va and the
2532 silc_command_payload_encode_va to support that if argument is
2533 NULL it ignores and checks the next argument. Affected file
2534 lib/silccore/silccommand.c.
2536 * Added silc_server_send_notify_ban to send the BAN notify
2537 type between routers.
2539 * Chaned the silc_notify_payload_encode to support that if
2540 argument is NULL it ignores and checks the next argument.
2541 Affected file lib/silccore/silcnotify.c.
2543 * Tested ban lists in router environment successfully.
2545 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Implemented BAN command to the server, in silcd/command.[ch].
2549 * Removed the BAN and INVITE_LIST modes from the CMODE command
2552 * Added function silc_string_match to regex match two strings.
2553 Affected files lib/silcutil/silcutil.[ch].
2555 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Redefined parts of the SilcChannelEntry in the server to support
2558 the new ban and invite lists.
2560 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Redefined the INVITE command. The same command can be used to
2563 invite individuals to the channel but also to manage the invite
2564 list of the channel (to add to and remove from the invite list).
2565 Updated the protocol specs.
2567 * Added new command SILC_COMMAND_BAN that can be used to manage
2568 the ban list of the channel. Updated the protocol specs.
2570 * Removed the channel modes: the SILC_CMODE_BAN and the
2571 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2572 in the CMODE command. The equivalent features are now available
2573 using INVITE and BAN commands. Updated the protocol specs.
2575 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2576 in the network about change in the current ban list. The notify
2577 type is not used by the client.
2579 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2580 support the invite lists.
2582 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Added new function silc_string_regexify that converts string
2585 including wildcard characters into regex string that can
2586 be used by the GNU regex library. Added into the file
2587 lib/silcutil/silcutil.[ch].
2589 Added silc_string_regex_combine to combine to regex strings
2590 into one so that they can be used as one regex string by
2591 the GNU regex library. Added into the file
2592 lib/silcutil/silcutil.[ch].
2594 Added silc_string_regex_match to match two strings. It returns
2595 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2597 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Imported GNU regex to the soruce tree into lib/contrib.
2600 Fixed some compiler warning from the regex.c.
2602 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2604 * Fixed MOTD command in the server to work in router environment.
2606 * Fixed the MOTD command in the client library to support
2607 the server argument in the command.
2609 * Added `nickname_len' argument to the silc_idlist_add_client
2610 in the server, as the `nickname' argument may be binary data
2613 * Added silc_idlist_get_channels to return all channels from
2616 * Implemented LIST command to the server. Affected file is
2619 * Implemented the LIST command to the client library and on the
2622 * Added [<user count>] argument to the LIST command reply.
2623 With private channels the user count is not shown.
2625 * Updated TODO and README.
2627 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * The client entry's data.registered must be TRUE even with
2630 global client entry on global client list. The data.registered
2631 is used to check whether the client is anymore in the network,
2632 for example with WHOWAS command so it must be valid.
2634 * Fixed the WHOWAS command in the server. It now actually works
2635 in router environment. Added function into silcd/command_reply.c
2636 silc_server_command_reply_whowas_save.
2638 * Added silc_idlist_purge function to the silcd/idlist.c
2639 to periodically purge the ID Cache.
2641 * Fixed INFO command in the server. It works now in router
2642 environment. Added <server name> argument to the INFO command
2643 reply. Updated the protocol specs.
2645 * Fixed minor bug in silc_idcache_purge to not purge if the
2646 expire value is zero.
2648 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2649 they were buggy because of the WHOWAS information.
2651 * Fixed local command MSG to handle the async resolving of
2652 the remote client properly. It used to fail the first MSG.
2653 Affected file silc/local_command.c.
2655 * Added `data_len' field to SilcIDCache context.
2657 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Update TODO. Todo in commands in the server.
2661 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2664 used by routers as broadcast packet to inform other routers
2665 about the changed user mode.
2667 Implemented the notify handling in the server. Affected file is
2668 silcd/packet_receive.c. Added the function
2669 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2671 * Added new generic Channel Payload and deprecated the New Channel
2672 Payload. The New Channel Payload is now the generic Channel
2675 * Added new argument `mode' to the silc_server_send_new_channel
2676 as it is required in the Channel Payload now.
2678 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2679 and created a new and real SilChannelPayload to represent the
2680 new generic Channel Payload. Implemented the encode/decode
2681 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2683 * Added silc_server_get_client_channel_list to return the list
2684 of channels the client has joined for WHOIS command reply.
2685 Affected file silcd/server.[ch].
2687 * Implemented the channel list sending in the WHOIS command reply
2688 in server and in the client.
2690 Implemented the channel list displaying on the user interface
2691 as well. Affected file silc/client_ops.c.
2693 * Added silc_channel_payload_parse_list to parse list of Channel
2694 Payloads. It returns SilcDList list of SilcChannelPayloads.
2695 Client for example can use this function to parse the list of
2696 channels it receives in the WHOIS command reply. The caller
2697 must free the list by calling silc_channel_payload_list_free.
2698 Affected files lib/silccore/silcchannel.[ch].
2700 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added one new argument <user mode> to the WHOIS command reply
2703 to return the mode of the user in SILC. Updated the protocol
2706 Implemented it to the server and client.
2708 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Fixed the mode printing on the user interface on joining.
2711 Affected file silc/client_ops.c.
2713 * Implemented the UMODE command and user modes in general to the
2714 client library and to the user interface.
2716 * Implemented the UMODE command to the server.
2718 * The server now sends UNKNOWN_COMMAND error status if client sends
2719 unknown command. Affected file silcd/command.c.
2721 * All server commands now handle the command identifier the right
2722 way when sending the command reply to the client. The client can
2723 use to identify the command replies with the identifier.
2725 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Added silc_server_get_client_route to resolve the route to
2728 the client indicated by the client ID. Affected file is
2731 * Added silc_server_relay_packet as general function to relay
2732 packet to arbitrary destination. This deprecates functions
2733 like _send_private_message_key, _relay_notify etc. Affected
2734 file is silcd/packet_send.[ch].
2736 Removed silc_server_send_key_agreement,
2737 silc_server_send_private_message_key and
2738 silc_server_packet_relay_notify functions from the file
2739 silcd/packet_send.[ch].
2743 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2744 server. Affected file silcd/packet_receive.[ch].
2746 * Implemented the KILL command to the client. Implemented the
2747 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2748 Affected files lib/silcclient/command[_reply].c and
2749 lib/silcclient/client_notify.c. Implemented the KILL notify
2750 printing in the user inteface.
2752 * Fixed a lot silc_parse_nick memory leaks from the client
2753 library in the file lib/silcclient/command.c.
2755 * Changed the silc_server_send_notify_on_channels's `sender'
2756 argument from SilcSocketConnection to SilcClientEntry to
2757 check the sender as entry and not as connection object and not
2758 to send to the client provided as argument. The affected file
2759 is silcd/packet_send.[ch].
2761 * The notify packets that are destined directly to the client used
2762 to not to be processed by the server. Now changed that and the
2763 server processes all notify packets. After relaying the packet
2764 to the client the notify packet is processed in the server.
2766 * The silc_server_free_client_data now checks whether there is
2767 pending outgoing traffic for the client and purges the data to
2768 the network before removing the client entry.
2770 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2773 an client is killed from the SILC Network. Updated the protocol
2776 Added new function silc_server_send_notify_killed to the
2777 silcd/packet_send.[ch].
2779 * Added function silc_server_packet_relay_notify to relay notify
2780 packets that are destined directly to a client. In this case
2781 the server does not process the notify packets but merely relays
2782 it to the client. Affected file silcd/packet_send.[ch].
2784 Added also silc_server_packet_process_relay_notify to check
2785 whereto relay the notify. Affected file is
2786 silcd/packet_receive.[ch].
2788 * Implemented the KILL command to the server.
2792 * Added the backup schema desgined last fall to the protocol
2793 specs for everyone to see. The specification is in the
2794 *-spec-xx.txt draft and the packet type definitions for the
2795 backup routers is in *-pp-xx.txt draft. Thusly, added also
2796 new packet type SILC_PACKET_CELL_ROUTERS.
2798 * A big security problem in the implementation discovered. The
2799 signoff of an client did not cause new channel key generation
2800 which it of course should've done. The channel keys must be
2801 always re-generated when client leaves (or signoffs) the channel.
2802 The silc_server_remove_from_channels funtion now handles
2803 the channel key re-generation.
2805 * Added `sender' argument to the silc_server_send_notify_on_channels
2806 to not to send the client provided as argument. Affected file
2807 silcd/packet_send.[ch].
2809 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Implemented OPER and SILCOPER commands into the server and
2814 * Added silc_auth_verify and silc_auth_verify_data to verify
2815 the authentication directly from the authentication payload.
2816 It supports verifying both passphrase and public key based
2817 authentication. Affected file lib/silccore/silcauth.[ch].
2819 * Added `hash' field to the SilcIDListData structure. It is the
2820 hash negotiated in the SKE protocol. Affected file is
2823 * Slight redesigning of the SilcAuthPayload handling routines.
2824 Do not send SilcPKCS but SilcPublicKey as argument.
2826 * Implemented the public key authentication support to the
2827 serverconfig. The public key is loaded from the provided path
2828 and saved as authentication data to void * pointer. Thus,
2829 changed the unsigned char *auth_data to void *auth_data;
2831 * Fixed SHUTDOWN command to send the reply before the server
2832 is shutdown. :) Affected file silcd/command.c.
2834 * Fixed fatal bug in CONNECT command. The hostname was invalid
2835 memory and server crashed. Affected file silcd/command.c.
2837 * Fixed fatal bug in CLOSE command. The server_entry became
2838 invalid but was referenced later in the command. Affected file
2841 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Fixed fatal bug in failure packet handling. Server ignored
2844 the failure and thus crashed when it came.
2848 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2851 that the command may be executed only once in (about) 2 seconds.
2852 The old SILC_CF_LAG flag is same but allows command bursts up
2853 to five before limiting.
2855 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2856 server code. Various commands now includes the CF_LAG_STRICT
2857 flag to disallow any kind of miss-use of the command.
2859 * Fixed the silc_buffer_unformat to not to allocate any data
2860 if the length of the data is zero. It used to allocate the
2861 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2863 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2865 * Changed the format of AdminConnection configuration section
2866 in the server. Added username of the admin to the format.
2867 Affected files silcd/serverconfig.[ch].
2869 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2870 to return admin configuration data by host, username and/or
2873 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Implemented WHOWAS command to the server. Added the functions:
2877 silc_server_command_whowas_parse,
2878 silc_server_command_whowas_send_reply,
2879 silc_server_command_whowas_from_client and
2880 silc_server_command_whowas_from_server
2882 * Added <Client ID> argument to the WHOWAS command reply. Updated
2883 the protocol specs accordingly.
2885 * Implemented WHOWAS command and command_reply to the client
2888 Implemented the WHOWAS printing on the user interface.
2890 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Added new argument to the WHOWAS command reply, the real name.
2893 It is an optional argument. Updated the protocol specs.
2895 * Added SilcIDCacheDestructor callback that is registered when
2896 the SilcIDCache is allocated. The callback is called when
2897 an cache entry in the ID Cache expires, or is purged from the
2898 cache. Added into lib/silccore/idcache.[ch].
2900 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2901 to destruct the client entries when the cache entry expires.
2902 Other ID Cache's in server and in the client library ignores
2905 * If the ID Cache entry's `expire' field is zero then the entry
2906 never expires. Added boolean `expire' argument to the
2907 silc_idcache_add function in the lib/silccore/idcache.[ch].
2908 If it is TRUE the default expiry value is used.
2910 * Added silc_server_free_client_data_timeout that is registered
2911 when client disconnects. By default for 5 minutes we preserve
2912 the client entry for history - for WHOWAS command.
2914 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Added support to the server to enforce that commands are not
2917 executed more than once in 2 seconds. If server receives
2918 commands from client more frequently, timeout is registered
2919 to process the commands. Affected file silcd/command.c.
2920 Added new function silc_server_command_process_timeout.
2922 * Changed NICK_NOTIFY handling in client library to check that
2923 if the client's nickname was changed, so there is no need to
2924 resolve anything from the server.
2926 * Removed error printing from the WHOIS and IDENTIFY commands.
2927 If error occurs then it is ignored silently in the client library.
2928 The application, however, may map the received error to
2929 human readable error string. The application currently maps
2930 the NO_SUCH_NICKNAME error to string.
2932 * Made the command status message public to the application. Moved
2933 them from lib/silcclient/command_reply.c to
2934 lib/silcclient/command_reply.h. The application can map the
2935 received command status to the string with the
2936 silc_client_command_status_message function.
2938 * Added check to the server to check that client's ID is same
2939 as the Source ID in the packet the client sent. They must
2942 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Added dist-bzip hook to the Makefile.am to make bzip2
2945 compressed distributions.
2947 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Server now enforces the maximum length for the nickname and
2950 the channel as protocol specification dictates. 128 bytes for
2951 nickname and 256 bytes for channel name.
2953 * Moved the WHOIS printing to the application. The client libary
2954 does not print out the WHOIS information anymore, the application
2955 must do it. Renamed silc_client_command_reply_whois_print to
2956 the silc_client_command_reply_whois_save.
2958 The client's idle time is also sent to the application now, and
2959 the idle is shown on screen.
2961 * Added silc_client_command_reply_identify_save to save the
2962 received IDENTIFY entries.
2964 * Do not check for channel private keys in message sending and
2965 reception if the channel does not have the PRIVKEY mode set.
2966 Affected file lib/silclient/client_channel.c.
2968 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2971 just surfaced after chaning the JOIN procedure.
2973 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Added silc_client_get_clients_by_list to get client entries
2976 from Client ID list, that is returned for example by JOIN
2977 and USERS command replies. The application should use this
2978 function for example when JOIN command reply is received to
2979 resolve the clients already on the channel (library does not
2980 do that anymore as USERS command reply is not used in the JOIN
2981 procedure anymore). Affected files lib/silcclient/silcapi.h and
2982 lib/silcclient/idlist.c.
2984 * JOIN command reply and USERS command reply returns now SilcBuffer
2985 pointers instead of unsigned char pointers when returning
2986 the client list and mode list.
2988 * Added <Client ID> argument to the JOIN command reply, mainly
2989 for the server to identify for which client the command was
2990 originally sent. Updated protocol specs accordingly.
2992 * Added SilcDlist private_key pointer to the SilcChannelEntry
2993 in the client to support the channel private keys. Affected
2994 file is lib/silcclient/idlist.h.
2996 * Added SilcChannelPrivateKey argument to the function
2997 silc_client_send_channel_message so that application can choose
2998 to use specific private ke if it wants to. If it is not provided,
2999 the normal channel key is used, unless private keys are set.
3000 In this case the first (key that was added first) is used
3001 as the encryption key.
3003 * Implemented the support for channel private key handling.
3004 Implemented the following functions:
3006 silc_client_add_channel_private_key,
3007 silc_client_del_channel_private_keys,
3008 silc_client_del_channel_private_key,
3009 silc_client_list_channel_private_keys and
3010 silc_client_free_channel_private_keys
3012 Affected file lib/silcclient/client_channel.c.
3014 * Added the support for the private keys in the channel message
3015 sending and encryption and in the message reception and
3016 decryption. Affected funtions are
3017 silc_client_send_channel_message and silc_client_channel_message.
3019 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Added SKE's key verify callback to the client library's
3022 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3024 * Removed the statement that server (or router) must send USERS
3025 command reply when joining to the channel so that the client
3026 knows who are on the channel. Instead, the client list and
3027 client's mode list is now sent in the JOIN command reply to the
3028 client who joined channel. This is better solution.
3030 * Added function silc_server_get_users_on_channel and function
3031 silc_server_save_users_on_channel to the silcd/server.[ch].
3033 * Removed function silc_server_command_send_users from the
3036 * Do not show topic on the client library anymore. The topic is
3037 sent in the command reply notify to the application and the
3038 application must show the topic now.
3040 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Added client searching by nickname hash into the IDENTIFY and
3043 WHOIS commands in the server as they were clearly missing from
3044 them. Affected file is silcd/command.c.
3046 * Fixed a bug in private message receiving in the client library.
3047 The remote ID was freed and it wasn't supposed, now it is
3050 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Minor fix to the channel payload; allocate the data area, as it
3053 needs to be of specific length.
3055 * If the key agreement port is zero then the operating
3056 system will define the bound port. Affected files are
3057 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3059 * Added new function silc_channel_payload_decrypt into the file
3060 lib/silccore/silcchannel.[ch].
3062 * Moved the channel message etc, check from silc_packet_decrypt
3063 to applications. The library calls now a generic
3064 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3065 when the packet is either normal or special. This was done to
3066 allow more wide range of checking that was not allowed when
3067 the code was in library. Now applications can do virtually any
3068 checks to the packet and return to the library the decision how
3069 the packet should be processed. Affected files are
3070 lib/silccore/silcpacket.[ch].
3072 Added silc_server_packet_decrypt_check to the server and
3073 silc_client_packet_decrypt_check to the client library.
3075 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3076 to send with specified source and destination information.
3078 * Channel message delivery between routers was broken after the
3079 channel key distribution was fixed earlier. The channel key
3080 was used be to distributed to other routers as well which is not
3081 allowed by the protocol. Now this is fixed and channel keys
3082 really are cell specific and the channel message delivery between
3083 routers comply with the protocol specification.
3085 * Fixed various commands in server to check also the global list
3086 for the channel entry and not just the local list. The affected
3087 file silcd/command.c.
3089 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Added assert()s to buffer formatting and unformatting routines
3092 to assert (if --enable-debug) when error occurs. Affected
3093 file: lib/silcutil/silcbuffmt.c.
3095 * Changed to auto-reconnect to check whether the remote host is
3096 router and register the re-connect timeout if it is. It used
3097 to check that whether we are normal server, but router must do
3098 auto-reconnect with another router as well. Affected file
3101 * Removed the [<key len>] option from CMODE command as the cipher
3102 name decides the key length, nowadays. See the defined ciphers
3103 from the protocol specification.
3105 * Added [<hmac>] option to the CMODE command to define the HMAC
3106 for the channel. Added SILC_CMODE_HMAC channel mode.
3108 * Added [<hmac>] option for the JOIN command so that user can
3109 select which HMAC is used to compute the MACs of the channel
3112 * Added Hmac field to the Channel Message Payload. The integrity
3113 of plaintext channel messages are now protected by computing
3114 MAC of the message and attaching the MAC to the payload. The
3115 MAC is encrypted. Now, it is clear that this causes some
3116 overhead to the size of the packet but rationale for this is that
3117 now the receiver can verify whether the channel message decrypted
3118 correctly and also when private keys are set for the channel the
3119 receiver can decrypt the packet with several keys and check from
3120 the MAC which key decrypted the message correctly.
3122 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3123 lib/silccrypt/silccipher.[ch].
3125 * Added silc_hash_len to return the digest length into the
3126 lib/silcrypt/silchash.[ch].
3128 * Rewrote parts of Silc Channel Payload interface in the
3129 lib/silccore/silcchannel.[ch]. The encode function now also
3130 encrypts the packet and parse function decrypts it.
3132 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Fixed a minor formatting bug in the SKE's key material processing.
3135 It actually might have processed the keys wrong way resulting
3138 * Redefined the mandatory HMAC algorithms and added new algorithms.
3139 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3140 and hmac-md5 truncated to 96 bits. The mandatory is now
3141 hmac-sha1-96. Rest are optional (including the one that used
3142 to be mandatory). Rationale for this is that the truncated HMAC
3143 length is sufficient from security point of view and can actually
3144 make the attack against the HMAC harder. Also, the truncated
3145 HMAC causes less overhead to the packets. See the RFC2104 for
3148 * Added new [hmac] configuration section. The SKE used to use
3149 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3150 is of course wrong. The official names that must be proposed in
3151 the SKE are the ones defined in the protocol specification
3152 (hmac-sha1-96 for example). The user can configure any hmac
3153 using any hash function configured in the [hash] section. At
3154 least, the mandatory must be configured.
3156 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3158 * Added HMAC list to the SKE proposal list. It has now both
3159 hash algorithm list and HMAC list. This makes the protocol
3160 incompatible with previous versions. The SKE now seems to work
3161 the way it is supposed to work, for the first time actually.
3163 * Defined plain Hash algorithms to the protocol specification.
3166 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Implemented support for key agreement packets into the server.
3169 Added functions silc_server_key_agreement and
3170 silc_server_send_key_agreement. Other than these functions,
3171 server has nothing to do with this packet.
3173 * Added support for private message key packets into the server.
3174 Added functions silc_server_private_message_key and
3175 silc_server_send_private_message_key.
3179 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3180 called in the protocol's final callback instead in the END
3181 protocol state. This makes a little more sense and in the same
3182 time in client we can use the same protocol routines for normal
3183 key exchange and to key agreement packet handling as well.
3185 * Added to both client's and server's KE protocol context the
3186 SilcSKEKeyMaterial pointer to save the key material. We will
3187 bring the key material to the protocol's final callback by doing
3188 this. The final callback must free the key material.
3190 * Added SKE's packet_send callback into client's KE protocol
3191 context so that the caller can choose what packet sending function
3192 is used. This way we can use different packet sending when
3193 doing normal SKE when doing key agreement packet handling (in
3194 the key agreement packet handling we do not want to encrypt
3197 * Implemented the responder side of the key agreement routines
3198 in the client. The client can now bind to specified port and
3199 accept incoming key negotiation. The key material is passed
3200 to the application after the protocol is over.
3202 * Implemented the processing of incoming Key Agreement packet
3203 in the client. Added function silc_client_key_agreement to
3206 * Implemented the intiator side of the key agreement routines
3207 in the client. The client can now initiate key agreement with
3208 another remote client. The key material is passed to the
3209 application after the protocol is over.
3211 * Created client_keyagr.c to include all the key agreement
3214 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3215 SILC_TASK_CALLBACK except that it is not static.
3217 * Created client_notify.c and moved the Notify packet handling
3218 from the client.[ch] into that file.
3220 * Created client_prvmsg.c and moved all private message and
3221 private message key routines from the client.[ch] into that file.
3223 * Create client_channel.c and moved all channel message and
3224 channel private key routines from the client.[ch] into that file.
3226 * Changed silc_client_get_client_by_id_resolve to resolve with
3227 WHOIS command instead of IDENTIFY command, in the file
3228 lib/silclient/idlist.c.
3230 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Implemented the SKE's responder side to the Client library.
3234 * When FAILURE is received to the protocol do not trust it
3235 blindly. Register a timeout to wait whether the remote closes
3236 the connection as it should do it, only after that process the
3237 actual failure. This was changed to both client and server.
3239 * Added client_internal.h to include some of the structures
3240 there instead of client.h in lib/silcclient/.
3242 * Added function silc_task_unregister_by_callback to unregister
3243 timeouts by the callback function.
3245 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Some "Incomplete WHOIS info" errors has been appearing on the
3248 log files. Took away the entry->userinfo check from WHOIS
3249 reply sending. The entry->userinfo is now " " if client did not
3250 provide one. I thought this was fixed earlier but something
3251 is wrong still. Let's see if the error still appears.
3253 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Fixed a minor bug in the login when the channel key is
3256 re-generated in the server. It used to generate the key in
3257 wrong order and thus caused problems in the channel traffic.
3259 * Fixed a minor bug in channel key distsribution after
3260 KICK command. The key was not sent to the router even though
3263 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Added silc_ske_process_key_material_data as generic routine
3266 to process any key material as the SILC protocol dictates. The
3267 function is used by the actual SKE library but can be used by
3268 applications as well. This relates to the private message keys
3269 and the channel private keys since they must be processed the
3270 same way the normal SILC session keys. The protocol dictates
3271 this. Affected files: lib/silcske/silcske.[ch].
3273 Added also silc_ske_free_key_material to free the
3274 SilcSKEKeyMaterial structure.
3276 * Defined silc_cipher_set_key function to set the key for
3277 cipher without using the object's method function. The affected
3278 files: lib/silccrypt/silccipher.[ch].
3280 * Implemented silc silc_client_add_private_message_key,
3281 silc_client_add_private_message_key_ske,
3282 silc_client_del_private_message_key,
3283 silc_client_list_private_message_keys and
3284 silc_client_free_private_message_keys functions in the
3287 Added functions silc_client_send_private_message_key to send
3288 the Private Message Key payload and silc_client_private_message_key
3289 to handle incoming Private Message Key payload.
3291 * Added Cipher field to the Private Message Key payload to set
3292 the cipher to be used. If ignored, the default cipher defined
3293 in the SILC protocol (aes-256-cbc) is used.
3295 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Removed lib/silcclient/ops.h file.
3299 Redefined parts of the SILC Client Library API. Created new
3300 file silcapi.h that deprecates the ops.h file and defines the
3301 published Client Library API. Defined also private message key
3302 API and channel private key API into the file.
3304 This is the file that the application must include from the
3305 SILC Client Library. Other files need not be included by
3306 the application anymore.
3308 * Added new key_agreement client operation callback and also
3309 defined the Key Agreement library API for the application.
3311 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3314 is used by clients to request key negotiation between another
3315 client in the SILC network. If the negotiation is started it
3316 is performed using the SKE protocol. The result of the
3317 negotiation, the secret key material, can be used for example
3318 as private message key.
3320 Implemented the Key Agreement payload into the files
3321 lib/silccore/silauth.[ch].
3323 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Redefined ciphers for the SILC protocol. Added some new ciphers
3326 and defined the key lengths for the algorithms. Changed the
3327 code accordingly. The default key length is now 256 bits.
3329 * Fixed SKE key distribution function silc_ske_process_key_material
3330 when the key length is more than 128 bits. The default key
3331 length in SILC is now 256 bits.
3333 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3334 to indicate unsupported algorithm.
3336 * Renamed rijndael.c to aes.c and all functions as well.
3338 * Fixed a long standing channel key setting bug in client library.
3339 Weird that it has never surfaced before.
3341 * Fixed bug in channel deletion. If the entire channel is removed
3342 then it must also delete the references of the channel entry
3343 from the client's channel list as the client's channel entry and
3344 the channel's client entry share same memory.
3346 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Implemented CONNECT and SHUTDOWN commands in the client.
3350 * Implemented CLOSE command to the client.
3352 * Added the function silc_idlist_find_server_by_name into the
3353 files silcd/idlist.[ch].
3355 Added the function silc_idlist_find_server_by_conn into the
3356 files silcd/idlist.[ch].
3358 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * DIE command was renamed to SHUTDOWN. Updated the both code
3363 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3364 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3366 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3369 * Added function silc_server_create_connection function to create
3370 connection to remote router. My server implementation actually
3371 does not allow router to connect to normal server (it expects
3372 that normal server always initiates the connection to the router)
3373 so the CONNECT command is only good for connecting to another
3376 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3378 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3379 or some other client was kicked from the channel.
3381 Implemented the handling of the notify type to both client
3384 Implemented silc_server_send_notify_kicked to send the KICKED
3385 notify. It is used to send it to the server's primary router.
3387 * Implemented the KICK command into server and client.
3389 * Added `query' argument to the silc_idlist_get_client function
3390 to indicate whether to query the client from server or not if
3393 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3394 to indicate that the client is not channel founder.
3398 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Removed the rng context from SilcPacketContext structure and
3401 changed that the packet routine uses the Global RNG API.
3403 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Added support for quit message that client can "leave" on the
3406 channel when it quits the SILC. It is ditributed inside the
3407 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3409 Added silc_server_free_client_data that will take the
3410 signoff message as argument.
3412 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3414 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3416 * Updated parts of the protocol specification to keep it up
3419 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3422 payloads in one packet.
3424 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3425 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3426 use now the new List flag.
3428 * Also deprecated the following packet types: REPLACE_ID,
3429 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3431 * Added list support for Notify packet in server.
3433 * Added silc_server_send_notify_channel_change to send the
3434 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3435 the silc_server_send_replace_id.
3437 * Added silc_server_send_notify_nick_change to send the
3438 NICK_CHANGE notify type. Deprecates the function
3439 silc_server_send_replace_id.
3441 * Added silc_server_send_notify_join to send the JOIN notify type.
3442 Deprecates the function silc_server_send_new_channel_user.
3444 * Added silc_server_send_notify_leave to send LEAVE notify type.
3445 Deprecates the function silc_server_send_remove_channel_user.
3447 * Added silc_server_send_notify_cmode and
3448 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3449 types. Deprecates the silc_server_send_set_mode function.
3451 * Added SERVER_SIGNOFF notify type to indicate that server has
3452 quit. This means that all clients on the channel from that
3453 server will drop. This can be also used when netsplit happens.
3455 Deprecated REMOVE_ID packet type since it is not needed anymore
3458 Added silc_server_send_notify_server_signoff to send the
3459 SERVER_SIGNOFF notify type. Deprecates the function
3460 silc_server_send_remove_id.
3462 Added also silc_server_send_notify_signoff to send the
3463 SIGNOFF notify type.
3465 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3466 SILC protocol from this day on. Changed the protocol
3467 specification as well.
3469 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3470 notify type. It is used between routers to notify about
3471 topic changes on a channel.
3473 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3476 * Partly updated the protocol specification to comply with the
3477 changes now made. It is still though a bit outdated.
3479 * The JOIN notify type now takes one extra argument <Channel ID>.
3480 The packet used to be destined to the channel but now the
3481 JOIN type may be sent as list thus it is impossible to
3482 destine it to any specific channel. By adding this argument
3483 it is again possible.
3485 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Added CREDITS file. The CHANGES and CREDITS file will appear
3488 in the distribution as well.
3490 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3493 types in the server's silcd/packet_receive.c.
3495 * Implemented CMODE and CUMODE to work in router environment.
3497 * Fixed minor encoding and decoding buglet from the
3498 lib/silccore/silcmode.c.
3500 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3503 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3505 * Changed all SilcConfigServer* and silc_config_server* to
3506 SilcServerConfig* and silc_server_config*, respectively.
3509 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Associated the ID (client or server ID) to the Authentication
3512 Payload to avoid any possibility of forging. Updated the
3513 protocol specification and the code accordingly.
3515 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * The RSA key length is now save to the RsaKey context in the
3518 key generation process in lib/silccrypt/rsa.c. The key length
3519 is now used to figure out the maximum size of the block allowed
3520 to be encrypted/signed.
3522 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3523 is equivalent to the silc_mp_mp2bin but does not allocate any
3526 * Changed silc_mp_mp2bin API to take length argument. If it is
3527 non-zero then the buffer is allocated that large. If zero, then
3528 the size is approximated using silc_mp_sizeinbase, which however
3531 * Created Global RNG API which is global RNG that application can
3532 initialize. After initializing, any routine anywhere in the
3533 code (including library) can use RNG without allocating a new
3534 RNG object. This was done to allow this sort of use of the
3535 RNG in code that has no chance to allocate RNG object. All
3536 applications currently allocate this and many routines in the
3537 library use this. Affected file lib/silccrypt/silcrng.[ch].
3539 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3540 it to use the Global RNG API.
3542 * Defined Authentication Payload into protocol specification that
3543 is used during SILC session to authenticate entities. It is
3544 used for example by client to authenticate itself to the server
3545 to obtain server operator privileges.
3547 Implemented this payload into the lib/silccore/silcauth.[ch].
3548 Implemented also routines for public key based authentication
3549 as the new protocol specification dictates.
3551 Moved definitions of different authentication methods from
3552 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3554 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3555 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3556 silc_pkcs_verify_with_hash functions into the file
3557 lib/silccrypt/silcpkcs.[ch].
3559 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * The client entry's userinfo pointer must be always valid.
3562 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3563 will fail since it requires the userinfo. Now, the userinfo
3564 is allocated as "" if actual userinfo does not exist. Actually,
3565 it must exist and it is totally Ok to drop client connections
3566 that does not announce the userinfo. However, we will make
3567 this workaround for now.
3569 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3570 to return the remote port by socket.
3572 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3575 SILC_SERVER_PENDING_EXEC and added an new macro
3576 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3577 data or when error occurs while processing the pending command.
3579 Added new argument `destructor' into silc_server_command_pending
3580 and to the SilcServerCommandPending object. This destructor is
3581 now called after calling the pending callback or if error occurs
3582 immediately. If error occurs the actual pending callback won't
3583 be called at all - only the destructor. The destructor may be
3584 NULL if destructor is not needed.
3586 All this applies for client library code as well. Similar
3587 changes were made there as well for the pending commands.
3589 In the client, the application must now allocate the
3590 SilcClientCommandContext with the silc_client_command_alloc
3593 * Added reference counter to the SilcServerCommandContext. Added
3594 function silc_server_command_alloc and silc_server_command_dup
3597 Same type of functions added to the client library for the same
3600 * Removed the cmd_ident from IDListData away since it is now
3601 global for all connections. It is the command identifier used
3602 in command sending and with pending commands. The affected file
3605 * Added reference counter to the SilcSocketConnection objecet to
3606 indicate the usage count of the object. The object won't be
3607 freed untill the reference counter hits zero. Currently only
3608 server uses this, and client ignores it. The client must be
3609 set to use this too later. The affected files are
3610 lib/silccore/silcsockconn.[ch]. Added also the function
3611 silc_socket_dup to increase the reference counter.
3613 This was mainly added because it is possible that the socket
3614 is removed underneath of pending command or other async
3615 operation. Now it won't be free'd and proper DISCONNECTING
3616 flags, etc. can be set to avoid sending data to connection that
3617 is not valid anymore.
3619 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3620 the connection. After that it sets SILC_SET_DISCONNECTED.
3621 It is, however, possible that the socket data is not still freed.
3622 The silc_server_packet_process now checks that data is not
3623 read or written to connection that is DISCONNECTED. The socket
3624 get's freed when the reference counter hits zero.
3626 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Changed the client operation API: channel_message operation's
3629 `sender' is now the client entry of the sender, not the nickname
3630 and the `channel' is the channel entry, not the channel name.
3632 In the private_message operation the `sender' is now also the
3633 client entry of the sender not the nickname.
3635 Affected file is lib/silcclient/ops.h and all applications
3636 using the client operations.
3638 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Moved the calling of ops->connect() from connect_to_server_final
3641 into receive_new_id functin since that is the point when the
3642 client is actually allowed to send traffic to network. The
3643 affected file is lib/silcclient/client.c.
3645 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3648 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3649 (if needs broadcasting) instead of broadcasting the packets one
3650 by one which would make a burst in the network traffic.
3652 * Added `broadcast' argument to the functions in silcd/server.[ch]
3653 silc_server_create_new_channel[_with_id] to indicate whether
3654 to send New Channel packet to primary router.
3656 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Added new function into the silcd/server.[ch] files:
3659 silc_server_create_new_channel_with_id to create new channel with
3660 already existing Channel ID.
3662 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3663 lib/silccore/silcpacket.h. This packet is used t send list of
3664 Set Mode payloads inside one packet. Server uses this to set
3665 the modes for the channels and clients on those channels, that it
3666 announced to the router when it connected to it. The protocol
3667 specification has been updated accordingly.
3669 * The silc_server_new_channel did not handle the packet coming
3670 from normal server as it normally does not send that. However,
3671 when it announces its channels it does send it. Implemented
3672 the support for that.
3674 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3675 into the file lib/silccore/id.h.
3677 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Fixed memory leaks in the functions silc_idlist_del_client,
3680 silc_idlist_del_channel and silc_idlist_del_server in the file
3681 silcd/idlist.c. All of those leaked like a sieve.
3683 * Fixed some small memory leaks in the client's function
3684 silc_client_notify_by_server.
3686 * Added functions into silcd/server.c: silc_server_announce_clients,
3687 silc_server_announce_channels and silc_server_announce_server.
3688 These functions are used by normal and router server to announce
3689 to its primary router about clients, channels and servers (when
3690 router) that we own. This is done after we've connected to the
3693 These functions effectively implements the following packet types:
3694 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3695 and SILC_PACKET_NEW_ID_LIST.
3697 * Added new functions into the silcd/packet_receive.[ch]:
3698 silc_server_new_id_list, silc_server_new_channel_list and
3699 silc_server_new_channel_user_list to handle the incoming
3700 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3702 * Added support of changing Channel ID in the function
3703 silc_server_replace_id. If the server that announces a channel
3704 to the router already exists in the router (with same name but
3705 with different Channel ID), router is responsible to send
3706 Replace ID packet to the server and force the server to change
3707 the Channel ID to the one router has.
3709 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3710 client that the Channel ID has been changed by the router. The
3711 normal server sends this to the client. Client must start using
3712 the new Channel ID as the channel's ID.
3714 Implemented handling of this new type into lib/silcclient/client.c
3715 into the function silc_client_notify_by_server.
3717 * Added new function silc_idlist_replace_channel_id into the files
3718 silcd/idlist.[ch] to replace the Channel ID.
3720 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Call silc_server_command_identify_check always when processing
3723 the IDENTIFY command in silcd/command.c
3725 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3728 send keepalive packets. The packet can be sent by clients,
3729 servers and routers.
3731 Added function silc_socket_set_heartbeat into the file
3732 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3733 If not set, the heartbeat is not performed. The actual
3734 heartbeat is implemented in the low level socket connection
3735 library. However, application is responsible of actually
3738 Added silc_server_send_heartbeat to send the actual heartbeat
3739 packet into silcd/packet_send.[ch]. Server now performs
3740 keepalive with all connections.
3742 * Added silc_task_get_first function into lib/silcutil/silctask.c
3743 to return the timeout task with shortest timeout. There was a bug
3744 in task unregistration that caused problems. TODO has been
3745 updated to include that task system must be rewritten.
3747 * The client library will now resolve the client information when
3748 receiving JOIN notify from server for client that we know but
3749 have incomplete information.
3751 * Rewrote parts of silc_server_remove_from_channels and
3752 silc_server_remove_from_one_channel as they did not remove the
3753 channel in some circumstances even though they should've.
3755 * Encryption problem encountered in server:
3757 The LEAVE command used to send the Channel Key packet to the
3758 router immediately after generating it. However, the code
3759 had earlier sent Remove Channel user packet but not immediately,
3760 ie. it was put to queue. The order of packets in the router
3761 was that Channel Key packet was first and Remove Channel User
3762 packet was second, even though they were encrypted in the
3763 reverse order. For this reason, MAC check failed. Now, this
3764 is fixed by not sending the Channel Key packet immediately but
3765 putting it to queue. However, this is more fundamental problem:
3766 packets that are in queue should actually not be encrypted
3767 because packets that are sent immediately gets encrypted
3768 actually with wrong IV (and thus MAC check fails). So, packets
3769 that are in queue should be encrypted when they are sent to
3770 the wire and not when they put to the queue.
3772 However, the problem is that the current system has not been
3773 designed to work that way. Instead, the packet is encrypted
3774 as soon as possible and left to the queue. The queue is then
3775 just purged into wire. There won't be any fixes for this
3776 any time soon. So, the current semantic for packet sending
3779 o If you send packet to remote host and do not force the send
3780 (the packet will be in queue) then all subsequent packets to the
3781 same remote host must also be put to the queue. Only after the
3782 queue has been purged is it safe again to force the packet
3785 o If you send all packets immediately then it safe to send
3786 any of subsequent packets through the queue, however, after
3787 the first packet is put to queue then any subsequent packets
3788 must also be put to the queue.
3790 Follow these rules and everything works fine.
3792 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Added new function silc_server_remove_clients_by_server to
3795 remove all client entries from ID list when the server connection
3796 is lost. In this case it is also important to invalidate all
3797 client entires as they hold the invalid server entry. This
3798 fixes fatal bug when server has lost connection and will reconnect
3801 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Made some sanity checks to silc_server_daemonise like to check
3804 whether the requested user and group actually exists.
3806 * Added sanity check to SKE's silc_ske_responder_finish to check
3807 that the public and private key actually is valid.
3809 * Invalidate the client's nickname when receiving Replace ID
3810 packet and the Client ID is being replaced. This means that the
3811 server will query the nickname if someone needs it (client)
3814 * Sort the ID Cache in client library when the ID Cache data
3815 has changed (needs sorting).
3817 * Do not allow for SILC client to create several connections to
3818 several servers. The client does not support windows right now
3819 and generating multiple connections causes weird behaviour.
3821 Irssi-silc client does support windows and can handle several
3822 connections without problems, see: www.irssi.org and SILC plugin.
3824 * Fixed some places where client was added to the IDList. The
3825 rule of thumb is following (in order to get everything right):
3826 If the client is directly connected local client then the
3827 `connection' argument must be set and `router' argument must be
3828 NULL to silc_idlist_add_client function. If the client is not
3829 directly connected client then the `router' argument must
3830 bet set and the `connection' argument must be NULL to the
3831 silc_idlist_add_client function.
3833 * The funtion silc_server_packet_send_local_channel actually did
3834 not check whether the client was locally connected or not. It
3835 does that now. Fixed a bug related to LEAVE command.
3837 * Fixed Remove Channel User payload parsing bug in server's
3838 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3840 * The server's silc_server_save_channel_key now checks also the
3841 global ID list for the channel as it might not be in the local
3842 list. Fixed a bug related to LEAVE command.
3844 * Is this the end of the [<unknown>] buglet that has been lurking
3845 around for a long time? A little for loop fix in server's
3846 silc_server_command_whois_parse that is used by both IDENTIFY
3847 and WHOIS command. At least, this was a clear bug and a cause
3848 of one type of [<unknown>] buglet.
3850 * WHOIS and IDENTIFY commands call the function
3851 silc_server_command_[whois/identify]_check function even if
3852 we are not router server.
3854 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Added --with-gmp configuration option. If set the GMP
3857 is always compiled in the SILC source tree. If not set then
3858 it is checked whether the system has the GMP3 installed. If
3859 it has then the GMP won't be compiled (the system's headers
3860 and library is used), if it doesn't have it then the GMP is
3861 compiled in the SILC source tree.
3863 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Changed RSA private exponent generation to what PKCS #1
3866 suggests. We try to find the smallest possible d by doing
3867 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3868 not security fix but optimization.
3870 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Added new config entry [Identity] to fork the server and run
3873 it as specific user and group. A patch from Bostik.
3875 * Imported Dotconf configuration library into lib/dotconf.
3876 This will be used to create the SILC configuration files later.
3877 It will appear in the distsribution after this commit.
3879 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * A big code auditing weekend happening. Auditing code for
3882 obvious mistakes, bugs and errors. Also, removing any code
3885 Removed files for being obsolete:
3887 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3888 inline in the file lib/silcutil/silcbuffer.h)
3890 o lib/silcutil/silcbufutil.c (the header has inline versions)
3892 Changed code to fix possible error conditions:
3894 o The buffer formatting routines now check that the destination
3895 buffer really has enough space to add the data. This applies for
3896 both buffer formatting and unformatting
3897 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3898 unformatting was changed to accomodate following rules:
3899 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3900 sent to the function while XXX_*STRING will not allocate or copy
3901 the data into the buffer. Instead it sets the pointer from the
3902 buffer into the pointer sent as argument (XXX_*STRING used to
3903 require that the pointer must be allocated already). This change
3904 makes this whole thing a bit more consistent and more optimized
3905 (note that the data returned in the unformatting with XXX_*STRING
3906 must not be freed now). The routines return now -1 on error.
3908 o Tried to find all code that use buffer_format and buffer_unformat
3909 and added return value checking to prevent formatting and
3910 especially unformatting errors and possible subsequent fatal
3913 o Changed ske->x and ske->KEY to mallocated pointers in
3914 lib/silcske/silcske.h. Fixed possible data and memory leak.
3916 o Added return value checking to all *_parse* functions. Fixed
3917 many memory leaks as well.
3919 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3920 so that buffer overflows would not happen. All code now also
3921 checks the return value as it can fail.
3923 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Added reconnection support to server if the normal server looses
3926 its connection to the router (for example if router is rebooted).
3927 The server performs normal reconnection strategy implemented
3928 to the server. Affected file silcd/server.c.
3930 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Added new packet type SILC_PACKET_SET_MODE that is used to
3933 distribute the information about changed modes (for clients,
3934 channels and clients channel modes) to all routers in the
3935 network. Updated the protocol specification accordingly.
3937 Added functions into silcd/packet_send.c and
3938 silcd/packet_receive.c: silc_server_send_set_mode,
3939 silc_server_set_mode.
3941 Added new files silcmode.[ch] into lib/silccore that implements
3942 the encoding and decoding of Set Mode Payload. Added new type
3943 SilcSetModePayload. Moved the definitions of different modes
3944 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3946 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Oops, a little mistake in server's connection authentication
3949 protocol. The protocol is not ended with FAILURE but with
3950 SUCCESS if the authentication is Ok. :) Affected file is
3953 * Implemented NICK_CHANGE notify handling in server in the file
3954 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3955 the local clients on the channel. After the changing nickname
3956 in router environment snhould work and the [<unknown>] nickname
3957 should appear no more.
3959 The silc_server_replace_id function that receives the Replace ID
3960 payload now sends the NICK_CHANGE notify type also in the file
3961 silcd/packet_receive.c
3963 * Changed WHOIS and IDENTIFY command to support the maximum amount
3964 of arguments defined in protocol specs (3328 arguments). This
3965 fixed a bug that caused problems when there were more than three
3968 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Added extra parameter, command identifier, to the
3971 silc_client_send_command so that explicit command identifier
3974 Changed that ID list routines uses specific command identifier
3975 when sending WHOIS/IDENTIFY requests to the server so that they
3976 can be identified when the reply comes back.
3978 Affected files lib/silcclient/command.[ch],
3979 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3981 * Added `sender' argument to silc_server_packet_send_to_channel
3982 to indicaet the sender who originally sent the packet to us
3983 that we are now re-sending. Ignored if NULL. Affected file
3984 silcd/packet_send.[ch].
3986 * Added some server statistics support in silcd/server_internal.h
3987 SilcServerStatistics structure and around the server code. Also
3988 send some nice statistics information when client is connecting
3991 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Fixed channel ID decoding in server's JOIN command reply in
3994 silcd/command_reply.c
3996 * Fixed braodcasting of replace ID payload to not to send it if
3997 we are standalone server in silcd/packet_receive.c.
3999 * Fixed all channel message sending routines to not to send
4000 packets to clients that has router set, since they are routed
4001 separately in the same function earlier. Affects file
4002 silcd/packet_send.c and all channel packet sending functions.
4004 * In USERS reply, res_argv[i] are not allocated, the table
4005 is allocated. Thus changed that free the table, not its
4008 * In server's whois_check and identify_check if the client is
4009 locally connected do not send any WHOIS commands - they are not
4012 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Fixed some minor bugs in client when sending WHOIS command. The
4015 arguments was in wrong order.
4017 * Removed statis function add_to_channel from server in
4018 silcd/command.c that was previously used with the joining but
4021 * Tested USERS command in router environment successfully with two
4022 routers, two servers and two clients.
4024 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Reorganized the USERS command and command reply in client library
4027 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4028 When the command is given by user we register a pending command
4029 callback that will reprocess the command after the reply has been
4030 received from the server. When reprocessing the packet we then
4031 display the information. Thus, the USERS information is displayed
4032 now in the command callback instead of in the command reply
4033 callback. The processing of the command is same as previously
4034 when server has sent the command reply in the JOINing process.
4036 * Added to USERS command in silcd/command_reply.c to join the client,
4037 we didn't use to know about, to the channel after we've created
4038 a client entry for it. Also, for clienet we did know already still
4039 check whether it is on the channel or not and add it if not.
4041 * Removed silc_server_command_join_notify as the function and its
4044 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Changed the client's pending command handling to the same as the
4047 server's pending command handling. It is also now possible to
4048 execute command reply functions from other command reply
4049 function as the function callbacks for commands and command
4050 replies are one and same. The pending commands are not static
4051 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4052 in client connection context. Thus, pending commands are server
4053 connection specific as it is convenient.
4055 Changed the function silc_client_command_pending and
4056 silc_client_command_pending_del and added new function
4057 silc_client_command_pending_check. Removed the
4058 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4061 * Added cmd_ident, current command identifier, to the client
4062 connection context in lib/silcclient/client.h to keep track on
4063 command identifiers used in command sending. Client's command reply
4064 function handling now supports the mandatory command identifiers.
4066 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4067 funtions in client to fully support pending command callbacks.
4069 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4070 as one of the arguments to the application in the command reply
4073 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4074 before first releasing SILC but came back. Now it is removed again
4075 and should come back nomore. The FORWARDED flag was used only
4076 by the JOINing procedure by forwarding the command packet to router.
4077 Now, the JOINing procedure has been changed to more generic (due
4078 to various router environment issues) and FORWARDED is not needed
4079 anymore for anything. The protocol specification is yet to be
4082 Now, removed silc_server_packet_forward from server and the flag
4083 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4085 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Renamed NAMES command to USERS command. The NAMES was named that
4088 due to historical reasons. Now it is renamed. Also, rewrote
4089 parts of the USERS command. The nickname list is not sent anymore
4090 by the server. Only Client ID and mode lists are sent in the USERS
4091 command. Changed this also to the protocol specification.
4093 The client now resolves the names and stuff after it receives
4094 the USERS list from the server when joining to the channel.
4096 * WHOIS and IDENTIFY commands has been changed to support multiple
4097 Client ID's per command. One can now search for multiple users
4098 in the network by sending only one WHOIS or IDENTIFY command.
4099 Changed the code and the protocol specifications.
4101 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4102 uses silc_server_command_whois_parse to parse the request. */
4104 * If normal server, do not parse the WHOIS and IDENTIFY requests
4105 before sending it to the router. Saves some time.
4107 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Fixed JOIN command on client library. Wrong number of arguments
4110 used to crash the client.
4112 * Added silc_server_channel_has_global function to check whether
4113 channel has global users or not.
4115 * Added silc_server_channel_has_local function to check whether channel
4116 has locally connected clients on the channel.
4118 * The silc_server_remove_from_one_channel now checks whether the
4119 channel has global users or not after given client was removed from
4120 the channel. It also checks whether the channel has local clients
4121 on the channel anymore. If it does not have then the channel entry
4122 is removed as it is not needed anymore.
4124 * The silc_server_notify now checks on JOIN notify whether the joining
4125 client is one of locally connected or global. If it is global then
4126 the channel has now global users on the channel and that is marked
4127 to the channel entry. Also, it now saves the global client to
4128 global list who is joining and JOINs it to the channel. This is
4129 for normal server, that is.
4131 Changed silc_server_send_notify_on_channel,
4132 silc_server_packet_relay_to_channel and
4133 silc_server_packet_send_to_channel check if we are normal server
4134 and client has router set (ie. global client) do not send the
4135 message to that client, as it is already routed to our router.
4137 * Implemented LEAVE notify type handling in silc_server_notify
4140 * Tested LEAVE command in router environment successfully. Tested
4141 with two routers, two servers and two clients.
4145 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4147 * Implemented SIGNOFF notify type handling in silc_server_notify
4150 * silc_server_remove_id now removes the client entry from all channels
4151 it has joined and thusly sends SIGNOFF notify type.
4153 * Rewrote the NAMES list generation in server by removing two excess
4154 loops. The lists are created now inside one loop.
4156 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * silc_server_remove_channel_user checks now also global list
4159 for channel and client.
4161 * silc_server_new_channel_user checks now both local and global
4162 list for channel and client. Fixed a bug in client id decoding.
4163 Used to decode wrong buffer.
4165 * silc_server_channel_message checks now both local and global
4166 list for channel entry.
4168 * Tested channel joining (hence JOIN) in router environment
4169 successfully. Tested with two routers, two servers and two
4172 * Tested channel message sending in router environment successfully.
4174 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added silc_server_save_channel_key into server.[ch] to save the
4177 received channel key in Channel Key payload processing. It is
4178 also used in JOIN command reply handling.
4180 Equivalent function silc_client_save_channel_key added into
4181 client.[ch] into client library.
4183 * Changed JOIN command reply to send information whether the channel
4184 was created or not (is existing already) and the channel key
4185 payload. Changed protocol specs accordingly.
4187 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4188 the request was sent by ID and not by nickname. Crashed on
4191 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4194 now correctly save the received data.
4196 * silc_server_free_sock_user_data now notifies routers in the
4197 network about entities leaving the network.
4199 At the same time implemented functions silc_server_remove_id
4200 and silc_server_send_remove_id to receive and send REMOVE_ID
4201 packets. The packet is used to notify routers in the network
4202 about leaving entities. The ID removed will become invalid in
4205 * Added function silc_idlist_del_server into server. Removes and
4206 free's server entry from ID list.
4208 * silc_server_private_message function now checks, if we are router,
4209 that the destination ID really is valid ID, naturally.
4211 * In router when NEW_ID packet is received (for new client) the
4212 hash of the Client ID is saved in the ID Cache but the
4213 client->nickname is set to NULL, instead of putting the hash
4216 IDENTIFY command now also checks that client->nickname must be
4217 valid. If it is not if will request the data from the server who
4218 owns the client. Added new function
4219 silc_server_command_identify_check.
4221 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4222 to set the command to already allocated Command Payload.
4224 * Tested private message sending in router environment with two
4225 routers, two servers and two clients. Fixed minor bugs and now
4228 * Fixed segfault from client's NAMES command. Used to crash if
4231 * Forwarded packets must not be routed even if it is not destined
4232 to the receiver. Changed server code comply with this.
4234 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Added `require_reverse_mapping' boolean value to ServerParams
4237 structure. If TRUE (not default) the server will require that
4238 the connecting host has fully qualified domain name.
4240 If the reverse mapping is not required and hostname could not be
4241 found the IP address is used as hostname.
4243 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Implemented version string checking to both client and server.
4246 The check is incomplete currently due to the abnormal version
4247 strings used in development version of SILC.
4249 * Changed all command functions in server to use the new
4252 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Changed char *data to unsigned char *data in ID Cache system to
4255 support binary data as ID Cache data. Changed code to support
4256 binary data in lib/silccore/idcache.c.
4258 * Renamed silc_server_packet_relay_command_reply to
4259 silc_server_command_reply as it is normal packet receiving
4260 function. Rewrote the function to accept command replys for
4261 servers and not only for clients.
4263 * Mark remote router always as registered server if we are connecting
4264 to it. Otherwise, commands sent by the router to us are ignored.
4266 * All ID List find routines now returns the ID Cache Entry pointer
4267 as well if requested.
4269 * WHOIS command works now in router environment, tested with two
4270 routers, two servers and two clients.
4272 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4273 in router environment (as it is almost equivalent to WHOIS) but
4274 hasn't been tested thoroughly. Added new functions:
4276 silc_server_command_identify_parse
4277 silc_server_command_identify_send_reply
4278 silc_server_command_identify_from_client
4279 silc_server_command_identify_from_server
4281 * Disabled route cache adding because adding two different ID's with
4282 same IP replaces the old cache entry thus giving wrong route.
4283 The entry->router->connection is always the fastest route anyway
4284 so route cache may not be needed. Of course, new routes maybe
4285 established after receiving the ID when the entry->router->connection
4286 might not be anymore the most optimal.
4288 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Add route cache for received ID for fast routing.
4292 * Added silc_server_packet_route to route received packet on router
4293 that is not destined to us.
4295 * Renamed silc_server_get_route to silc_server_route_get.
4297 * Added id_string and id_string_len fields into SilcServer to
4298 include encoded ServerID for fast comparing without excess
4299 encoding of the ID's.
4301 * Cleaned up WHOIS command on server side. Added following static
4304 silc_server_command_whois_parse
4305 silc_server_command_whois_check
4306 silc_server_command_whois_send_reply
4307 silc_server_command_whois_from_client
4308 silc_server_command_whois_from_server
4310 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4311 arguments in command replies. All command functions should be
4312 updated to use this macro.
4314 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Minor typo fixes on command reply handling on server.
4318 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Added silc_server_command_add_to_channel internal routine to add
4321 the client to the channel after router has created the channel and
4322 sent command reply to the server.
4324 * Added generic silc_server_send_command to send any command from
4327 * Use static buffer with ID rendering instead of duplicating data.
4329 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Fixed a channel user mode bug when joining to a channel server gave
4332 everybody channel founder rights, oops.
4334 * We mark ourselves as the router of the incoming server connection
4335 if we are router ourselves. This way we can check in some packet
4336 sending functions whether it is locally connected server. For
4337 incoming router connections we put NULL.
4339 * For router sending packets locally means now always sending the
4340 packet cell wide; to local clients and local servers. For normal
4341 server sending packet locally means sending it to only local
4344 * Fixed the JOIN command to really work in router environment. If the
4345 channel is created it is always created by the router. Router is
4346 also responsible of making the initial joining to the channel,
4347 sending JOIN notify to the sending server and distributing
4348 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4349 does not exist server doesn't do anything else but forward the
4350 command to the router which performs everything.
4352 * Added silc_server_send_channel_key function to send the Channel Key
4355 * Added silc_server_create_channel_key to create new channel key. The
4356 channel key is now re-generated everytime someone joins or leaves
4357 a channel, as protocol dictates. Note: channel->key_len is the
4360 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4363 packet_receive.[ch] to separate packet sending and receiving
4364 routines. The server.[ch] now includes everything else including
4365 actual packet processing (writing and reading data) and other
4368 Renamed silc_server_private_message_send_internal to
4369 silc_server_send_private_message. The routine is still though
4370 used only to relay private messages as server does not send
4371 private messages itself.
4373 Renamed silc_server_new_channel to silc_server_create_new_channel
4374 and added new function sicl_server_new_channel that handles the
4375 incoming New Channel packet. Added also new sending function
4376 silc_server_send_new_channel to send New Channel Payload.
4378 * Added new function silc_server_notify to process incoming notify
4379 packet to the server/router. Server may then relay the notify
4380 to clients if needed.
4382 * Added new function silc_server_new_channel_user to process incoming
4383 New Channel User packet. Router will redistribute the packet and
4384 send JOIN notify to its local clients and locally connected servers
4385 if needed. Normal server will send JOIN notify to its local client
4386 on same channel when received this packet. Added also corresponding
4387 sending function silc_server_send_new_channel_user to sent the
4390 * Added boolean route argument to send_notif_to_channel and
4391 packet_send_to_channel functions to attempt to route the packet
4392 if it is TRUE and send only locally if it is FALSE.
4394 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * silc_server_replace_id now broadcasts the received replace ID
4397 packet if it is not broadcast packet already. The router must
4398 broadcast to inform other routers about changed ID.
4400 * Added backpointer to server's router into SilcServer context in
4401 silcd/server_internal.h.
4403 * Fixed silc_server_packet_broadcast to send correct broadcast
4406 * The channel key is now distributed to the local client as soon
4407 as it is received from the router (in router environment) so that
4408 no other packet may be sent for the channel until client has
4411 * silc_server_remove_channel_user now broadcasts the received
4412 Remove Channel User packet if it is not broadcast packet already.
4413 The router must broadcast to inform other routers about removed
4416 * Added users field into SilcPacketContext that is a reference count
4417 of the context. One can increase the reference count by calling
4418 silc_packet_context_dup which is now changed to just increase the
4419 reference count instead of duplicating the data. The reference
4420 count is decresed by calling silc_packet_context_free that will
4421 free the data after the reference count hits zero.
4423 For now on the packet context and everything allocated into it
4424 (including the raw packet from network) must be freed by calling
4425 the new silc_packet_context_free function. Added also new function
4426 silc_packet_context_alloc that must be used now to allocate the
4427 context. This also means that if a routine is asynchronous from
4428 silc_[client/server]_packet_parse_type the packet context must
4429 be duplicated by calling silc_packet_context_dup. Otherwise it
4430 gets free'd after silc_[client/server]_packet_parse_type returns.
4431 Also, one must remember that if packet is duplicated then its
4432 reference count must be decresed by calling the free function as
4433 many times as it was duplicated.
4435 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4436 from both client and server.
4438 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Made joining to a channel working in router environment.
4442 * Cleaned up JOIN command on server side and create function
4443 silc_server_command_join_channel internal routine to make the
4446 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Changed silc_command_pending list to SilcDList. Also, added
4449 `ident' field to SilcServerCommandPending structure to identify
4450 the reply and to call correct callback.
4452 Added silc_server_command_pending_check function to replace the
4453 corresnponding macro. The silc_command_pending list is not
4456 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4457 to set identifier to previously allocated Command Payload. It
4458 is used to set identifier for command when resending Command
4461 * Added silc_command_payload_encode_payload to encode Command
4462 Payload buffer from SilcCommandPayload structure.
4464 * Added silc_argument_payload_encode_payload to encode Argument
4465 payload buffer from SilcArgumentPayload structure.
4467 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Changed WHOIS command to support router connection on server side.
4470 The whois request is always sent to router unless the server is
4471 standalone server. After server has received the reply from the
4472 router will it send the reply to the client.
4474 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4475 broadcast received broadcast packet. The function is used only
4476 by router. The broadcast packet is always sent to the router's
4479 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4480 render given ID to printable string, for log files for example.
4482 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Made basic router to router connections working. At least they
4485 can now connect to each other but nothing really works the way
4486 they are supposed - yet.
4488 * Added new initiator token to RouterConnection configuration
4489 file in silcd/serverconfig.[ch]. It is used to tell whether we
4490 are the initiator to the remote router or whether we'll expect
4491 the other end to connect.
4493 * Moved registering of listener task to silc_server_init, hence
4494 the server starts listenning as soon as it is run, even if it
4495 does not have connections to other routers. Let's see how well
4498 * Changed default connection retry timeouts for more suitable in
4501 * Removed cipher and such arguments from silc_idlist_add_client
4502 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4503 Added new function silc_idlist_add_data to add the keys and stuff
4506 * Added SilcIDListData structure and added it to SilcClientEntry
4507 and SilcServerEntry as their first field in the structure. This
4508 way we can explicitly cast the ID entries to the SilcIDListData
4509 structure and get common data for the entries. In past, we had
4510 to first check what type of connection it is and then cast it to
4511 correct ID entry type. Now, we can directly cast the opaque
4512 pointer to the SilcIDListData (no matter what ID entry it actually
4513 is) and get the data needed.
4515 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4518 in some circumstances even if threre were timeout tasks, though not
4519 IO tasks, but tasks anyway. Now fixed.
4521 * Defined SilcServerConnection structure to hold connection specific
4522 stuff about directly connected servers and routers. The definition
4523 is currently in silcd/server_internal.h. I thought about having
4524 a bit more important role fro this struct but for now it is used
4525 only when connecting to other server (or router actually).
4527 * Added connecting retry support in server when connecting to
4528 router(s). The retry feature implement exponential backoff
4529 algorithm. Also, added SilcServerParams structure to hold default
4530 parameters for server. For now, it include these retry settings
4531 and are hard coded. After server is moded to be as Silc Server
4532 Library this structure will be more important.
4534 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Changed client librarys channel->clients table to SilcList and
4537 changed code accordingly.
4539 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Changed client's channel table to SilcList and changed code
4542 accordingly. Also changed SilcChannelClientEntry to include back-
4543 pointer to the channel so that client entry can use that structure
4544 as list as well and we have fast cross-reference to the channel.
4545 This change dramatically decreased the complexity of channel
4546 handling with client entry and vice versa (removed one extra
4547 loop when searching for channel entry from many functions).
4549 * Changed server->sim from table to SilcDList and changed code
4552 * NAMES command can now be used from user interface. It will show
4553 the user list on the channel, neatly.
4555 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4556 Code now saves realname of the user if it becomes available.
4558 * Renamed configure.in to configure.in.pre and made ./prepare
4559 script to automatically add correct version string to
4560 configure.in which it creates from configure.in.pre.
4562 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * NAMES command reply now shows users mode with the nickname when
4567 * Moved silc_client_ch[u]mode[_char] functions from
4568 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4569 place sucks, they are utility functions and should be in some
4572 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4574 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4577 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added TRQ (efficient deque and list library) into lib/trq. This is
4582 a very good list library that is currently used in the SILC. Defined
4583 SilcList API over the library because I didn't like the API very
4584 much. See lib/trq/silclist.h for the API and examples of how to
4585 use the API. Fixed various places in the code to use the new
4586 SilcList API. The SilcList is meant for lists that has a structure
4587 already defined as a list. It is not suitable to add just some
4588 context to the list (in TRQ, the context is the list actually).
4590 So, I defined SilcDList that can be used for the purpose where
4591 predefined list structure does not exit. This can be used as
4592 such list. Now some context just can be added to the SilcDList.
4593 Currently this list is not used in the SILC just yet, though there
4594 are a lot places where this can replace dynamically allocated
4595 tables and I will fix these places, later, to use SilcDList.
4596 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4597 and use TRQ internally).
4599 Also fixed some annoying warning messages that the original TRQ
4600 code generated. Also minor changes to TRQ's Makefile.in.
4602 * Added support for querying by Client ID to both WHOIS and
4603 IDENTIFY commands into server, as required by the protocol.
4605 * Removed method function pointers from SilcBuffer structure. They
4606 weren't used to anything and just increased the context size for
4607 no good reason. This change also made silc_buffer_alloc and
4608 silc_buffer_free functions inline functions.
4610 * Disabled command flooding detection support until it's fixed so
4611 that it accepts commands in but does not execute them more than once
4614 * Added silc_net_localhost(), to return local hostname, into
4615 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4616 that must be initialized before calling silc_client_init.
4618 * Added new function: silc_server_send_notify_on_channels to send
4619 notify messages to all channels client has joined. It is assured
4620 that the message is sent only once per client.
4622 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4623 lib/silcutil/silcutil.[ch] as silc_format function. The new
4624 function is generic and is used by server as well, not only by
4625 the logging routines.
4627 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4628 the provided version string was not acceptable. Added new function:
4629 silc_ske_check_version into lib/silcske/silcske.h. The function
4630 must be implemented by the application (client or server) and it
4631 does not reside in the SKE library. The function checks the version
4632 string remote end sent.
4634 * Added back pointers (to opaque context and to SilcSocketConnection)
4635 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4637 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4638 duplicate packet context structure.
4640 * Changed `notify' client operation to send same arguments as client
4641 receives from server except for ID's. ID's are mapped to correct
4642 ID entry and that is returned. Also, if channel entry is not sent
4643 by server but the notify is for channel the channel entry is sent
4644 to application (otherwise application doesn't know that it is for
4645 channel (library gets it from packet's Destination ID)).
4647 * Added silc_client_remove_from_channels into client library to
4648 remove a client from all channels it has joined to. Used when
4649 received SIGNOFF notify from server. Added also new function
4650 silc_client_replace_from_channels to replace old ID entry with
4651 new ID entry on all channels. Used when received NICK_CHANGE
4654 * Fixed ID Cache list handling in silc_idlist_get_client in
4655 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4656 to get (or query) client by ID.
4658 * Updated TODO list.
4660 * Added connection authentication status message defined by the
4661 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4662 support for these into the code in client and server side.
4664 * Added generic function silc_client_send_command to send any command
4665 with variable argument list. Application should use this function
4666 to send commands if the command functions provided by the library
4667 does not suite for the application's user interface needs.
4669 * Added new `failure' client operation. Application is notified about
4670 received failure packet if client is executing a protocol. In this
4671 case the protocol's execution has failed.
4673 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4674 is required by the protocol.
4676 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4677 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4680 * Added status flag to SilcSKE object to indicate realtime status
4681 of the SKE protocol.
4683 * Application receives now exactly same command reply arguments as
4684 the library receives from server. However, if ID is received the
4685 corresponding ID entry is returned to the application (eg. Client
4686 ID is mapped to correct SilcClientEntry entry and that is returned).
4687 Changed command_reply client operation due to this change.
4689 * Changed all ID's in commands and in command replys as ID Payloads.
4690 Change affected both client and server side codes.
4692 All ID's sent in SILC network (with execption of ID's in SILC
4693 Packet header) are sent in ID Payload to support variable length
4696 * Server now notifies nick changes and notifies all clients on
4697 the channels about the new nickname (about the new Client ID,
4700 * Implemented CMODE command to change channel modes. Supports all
4701 channel modes defined by the protocol specs except ban and invite
4702 lists. (Also, private channel key mode is supported but support for
4703 setting private channel key in client is missing, thus, this mode
4704 has no effect on client side (except that server requires that the
4705 client uses private channel key and normal channel traffic does not
4708 Also, invite mode works per se, but INVITE command does not work
4709 yet correctly, so you can set channel as invite only channel but
4710 inviting clients to the channel does not work (it is yet to be
4711 thought what's the best way to do it).
4713 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4714 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4715 Implemented CUMODE command to change user's mode on the channel.
4716 Supports all modes defined by the protocol specs.
4718 * Added NAMES command reply to return users modes on the channel.
4720 * Removed unnecessary and slow ciphers from lib/silccrypt.
4722 * Set SO_KEEPALIVE option to connection sockets by default.
4724 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4726 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4727 redefined the Notify Payload into protocol specs.
4729 * Added silc_id_payload_parse_id to get ID directly from raw
4732 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4735 accept searching by Client ID as well.
4737 * Added support for LEAVE and SIGNOFF notify types in client library.
4739 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4740 to parse ID Payload from raw data.
4742 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added flags parameter into silc_ske_assemble_security_properties
4745 function in lib/silcske/silcske.[ch].
4747 * Changed notify client operation to fit better for notify messages
4748 sent by server. The notify payload received from server is now
4749 passed to the application (after parsing it to SilcNotifyPayload).
4750 It is application's responsibility to retrieve the arguments
4751 from the payload and show the message the way it wants. The message
4752 sent by server is implementation specific.
4754 * Changed public keys to comply with the protocol specification.
4755 Old public keys are not supported anymore and are not compatible.
4757 * Removed nickname from Channel Payload as the latest draft removed
4758 it. The client must resolve the nickname from the NAMES command
4759 reply received when it joined the channel.
4761 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4763 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Fixed some errors in protocol specification drafts.
4767 * Created lib/silccore/silcnotify.c to implement Notify Payload
4768 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4769 generic payloads described by protocol specifications. The file
4770 includes implementations for ID Payload and Argument Payload.
4772 * Changed Command Payload implementation to use the new Argument
4773 Payload. Changed command_xxxx_payload to command_payload_xxxx
4774 to comply with SILC coding conventions.
4776 * Added suppport for Argument Payload handling in Notify Payload
4777 implementation as protocol requires it. Added the new support
4778 into server and client lib as well.
4780 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Added support for multiple nicknames on same channel. [n] is
4783 added locally to the nickname if there are more than one same
4784 nicknames on the channel.
4786 * Server now sends all nicknames that matched WHOIS request.
4787 Client also shows the list received from server.
4789 * Added TOPIC command to client side. User can now set and show
4790 current topic on channel.
4792 * Added MOTD command to client and server. Also, server sends the
4793 motd when client connects to the server.
4795 * Changed version strings to comply ISO 8601.
4797 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Fixed protocol error handling in client library. It should now
4800 cope even if the SKE fails for some reason.
4802 * Made new protocol specification drafts for submitting to IETF.
4804 * Implemented TOPIC command to server in silcd/command.c.
4806 * Added two new notify types into lib/silccore/silcnotify.h:
4807 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4808 notify nickname change and topic setting/change on a channel.
4810 * API change of command_reply operation in client library. The
4811 application gets now the status type received from server as well.
4813 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4817 * Cras fixed and optimized the packet handling even further and
4818 it should work now. Minor change to the prototype of function
4819 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4821 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Added new function into lib/silcutil/silcschedule.[ch]:
4824 silc_schedule_with_fd to select() a specified fd. The function
4825 returns after timeout expires or data arrives or goes. The
4826 function is used by packet routines to wait that all data is
4827 received from network.
4829 * Fixed data reading from network in lib/silccore/silcpacket.c.
4830 The code now assures that all data is read from the fd and then
4831 continues packet processing. This was a bug fix since the code
4832 used to drop some data in some circumstances.
4834 * Added new function into lib/silcclient/client.[ch]:
4835 silc_client_start_key_exchange to start key exchange after
4836 connection has been established to server. The code internally
4837 now uses this funtion but its main purpose was to provide it
4838 for applications that perform their own connecting. After
4839 application has created a connection it merely calls this
4840 function to start the key exchange between client and server.
4841 The library takes care of everything else after that.
4843 Updated also lib/silcclient/README to explain the usage of
4846 * Do not send to application information that connection has
4847 been established. Application gets notified it by connect
4850 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Applied cras's patch to add silc_schedule_one function. The
4853 function runs scheduler once and returns.
4855 * Fixed the scheduler after cras messed it up. The timeout
4856 handling works now as it's supposed to work.
4858 * Added into lib/silccore/ silcnotify.h to include notify
4859 message types support. Changed silc_server_send_notify*
4860 functions, in server.[ch], to support those new notify types.
4861 Added the support for the notify types into client library,
4862 as well. Added new notify client operation into ops.h in
4865 * Changed silc_server_packet_send_to_channel to send normal
4866 packets instead of just channel message packets. The function
4867 is now used to send the notify packets to channels. It is not
4868 used to send channel message packets anymore, as server never
4871 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4872 va_arg()s as it seems to require it nowadays. I guess, if SILC
4873 is compiled with older va_arg() the new code should work anyway.
4875 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Splitted core library. Core library (lib/silccore) includes
4878 now only SILC protocol specific core (and common) components.
4879 Created new utility library (lib/silcutil) that includes more
4880 generic purpose stuff. The stuff for util library was taken
4881 from the old core library. This was minor and easy split.
4883 * Created SILC Client Library (lib/silcclient) that includes
4884 implementation of the SILC client without user interface. This
4885 was major move from silc/ directory. The code has been changed
4886 so that it is transparent towards the user interface. The
4887 silc/ directory includes now the same user interface as before
4888 and it uses the new client library. Read lib/silcclient/README.
4889 Basicly, the client library performs everything else related
4890 to SILC except user interface handling. Also, configuration
4891 files are considered to be part of user interface and library
4892 does not handle them.
4894 This change also changed a lot of structures, function naming etc.
4895 Most important change was that SilcClientWindow object was
4896 renamed to SilcClientConnection in the client library. Created
4897 also new file lib/silcclient/ops.h. Also added new files
4898 silc/local_command.[ch] and silc/client_ops.[ch].
4900 All these changes were made to make it easier for user interface
4901 designers to create what ever user interface for the SILC client
4904 It is also expected that the server will be moved to lib
4905 directory as well and SILC Server Library will be created;
4906 sometimes in the future.
4908 * Removed Local commands from lib/silccore/silccommand.h as
4909 they are application specific and new client library does not
4910 handle any of those anymore.
4912 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4913 old client implementation in silc/.
4915 * Added support for callback functions in SILC_LOG_* macros.
4916 Application can now set its own callbacks that will be called
4917 instead of using the default functions that will always print
4918 the debug messages to stderr (or stdout). Also, debugging can
4919 now be disabled by setting silc_debug to FALSE and re-enabled by
4920 setting it to TRUE. Note, that logging will still work even
4921 if debugging is disabled.
4923 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4924 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4925 silc_log_reset_debug_callbacks.
4927 * To enable debugging in silc client one must give now -d
4928 option on command line.
4930 * Changed silc_schedule_init to automatically allocate task queues
4931 if they are not allocated before calling it.
4933 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added GMP 3.1 into math library.
4937 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4940 a channel in SILC network. The packet is used by servers and
4941 routers to notify other routers that user has left a channel.
4942 This little feature was missing until now. Added the feature
4943 to protocol specification as well.
4945 Added functions: silc_server_send_remove_channel_user and
4946 silc_server_remove_channel_user into server.[ch].
4948 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4949 lib/silccore/silcpacket.h. However, they are not implemented
4952 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Fixed joining to a channel and sending channel messages
4955 between server and router. The channel message sending should
4956 now work inside a cell.
4958 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Fixed the private message sending between server and router.
4961 The private message sending should now work inside a cell.
4963 * Added silc_server_replace_id into server.[ch] to replace
4964 existing ID in the SILC network.
4966 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4967 and silc_idlist_replace_server_id into idlist.[ch] in server.
4969 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Fixed the server to server connections. Server can again now
4972 connect to router. Router to router connections probably does
4975 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Added dynamic protocol registering support. Now protocols can
4978 registered and unregistered on the fly. Patch by cras.
4980 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Added lib/contrib directory to hold routines that some platforms
4983 don't have but are needed by SILC.
4985 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4986 into lin/contrib to provide getopt() and getopt_long() for
4987 those who don't have it.
4989 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Added AWAY command to client. When away message is set and
4992 client receives a private message packet the client automatically
4993 replies to the sender with the away message.
4995 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4996 bug seemed to be the cause of recent problems when compiling
4999 * Added version detection support to SKE protocol specification
5000 and added the new changes to the SKE implementation as well.
5001 There were other minor changes in the SKE protocol as well.
5003 Many changes in lib/silcske/silcske.[ch] and in
5004 lib/silcske/payload.[ch].
5006 * Added ^U functionality, clear input line. Patch from cras.
5008 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Mainly small bugfixes on core library. Fixed some debugging
5011 logging and buffer overflow in silclog.c.
5013 * Updated config.sub and config.guess on the distribution tree.
5015 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Added command lagging support in server. Client may execute
5018 commands now only once in two seconds.
5020 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Optimized packet reception. MAC computation and checking is now
5023 also more optimized. A lot previously duplicated code is now
5024 used as generic by both client and server.
5026 * Fixed key pair generation in clientutil.c
5028 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added into lib/silccore/silcbufutil.[ch] new function;
5031 silc_buffer_realloc.
5033 * Moved generic packet sending/encryption functions to
5034 lib/silccore/silcpacket.[ch] from client and server. Some
5035 rewriting of the functions.
5037 * Moved all generic packet reception/decryption functions to
5038 lib/silccore/silcpacket.[ch] from client and server. The
5039 packet processing is now much cleaner in both client and server.
5040 These were major changes in both client and server.
5042 * Created many common functions in server to do packet sending.
5043 Previously code were duplicated a lot, this has been removed
5046 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Rewrote major parts of the ID cache system. Don't know
5049 whether it is better now or not but at least the API is more
5052 * Major rewrite on ID cache stuff on client because of the ID
5053 cache API changes. Added idlist.c to client.
5055 * Also major rewrite on ID cache stuff on server as well.
5056 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5057 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5058 in hand, instead they are all put into the ID cache system now.
5059 All server_idlist_* routines uses ID cache now instead of
5060 traversing its own lists (those lists does not exist anymore).
5061 SilcIDList though still exists. Also, SilcXXXEntry's are
5064 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Finally made the SKE implementation compliant to the protocol
5067 specification. All mp integers are now binary encoded as
5068 opposed being HEX encoded.
5070 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5073 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5074 functions: silc_[encode/decode]_pem. Also added function
5075 silc_encode_pem_file to PEM encode with newlines ('\n') for
5078 * SILC public keys are now encoded either PEM or binary. Same
5079 option is for private keys as well. By default private keys
5080 are binary encoded and public keys PEM encoded. Silly HEX
5081 encoding were removed.
5083 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5084 function to create fingerprints.
5086 * Fixed a bug in SHA1; does not change the original data anymore.
5088 * Partly implemented INFO command on client and server side.
5089 Fixed CLEAR command. Changes to SERVER command; show current
5090 server(s) when giving command without arguments. Added
5091 VERSION command to client.
5093 * Added check to server that unregistered connections cannot
5094 execute commands (unless it is specificly allowed).
5096 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Fixed screen refresh.
5100 * Fixed channel joining bug from client. On some circumstances
5101 client tried to join to a channel it had already joined.
5103 * Added public key verification process into client's protocol.c.
5104 The client now verifies the public key from user and saves
5105 it into ~./silc/serverkeys/ directory.
5107 Added into: clientutil.[ch]: silc_client_verify_server_key.
5109 * Changed SKE protocol's silc_ske_initiator_finish function
5110 to accept callback function that verifies the received public
5111 key. Removed old silc_ske_verify_public_key function.
5113 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5116 silc_pkcs_private_key[_data]_set.
5118 * Made the password and public authentication more cleaner in
5119 server's protocol.c.
5121 * Removed historic and obsolete protocol `channel_auth' from
5122 both client and server.
5124 * Removed wrong way of sending command status messages from
5125 server to client in server's command.c. The old way violated
5126 protocol specification.
5128 Changes to silccore/silccommand.[ch]: removed
5129 silc_command_encode_status_payload -> not needed anymore,
5130 changed silc_command_encode_payload_va to accept extra
5131 argument on variable argument list. The argument type must
5132 now be provided to the function. Also, added new function:
5133 silc_command_encode_reply_payload_va which is same as
5134 normal command_encode_payload_va except command status type
5135 is provided as extra argument.
5137 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Added ~./silc directory handling. The directory includes the
5140 public and private keys for the client.
5142 Added silc_client_check_silc_dir, silc_client_create_identifier
5143 and silc_client_load_keys.
5145 * Implemented SILC protocol compliant public key. Added public
5146 and private key saving to and loading from files.
5148 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5149 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5150 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5151 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5152 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5154 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5155 silc_pkcs_load_[public/private]_key.
5157 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Added silc_server_get_route (route.[ch]) to get connection
5160 data for the fastest route for given ID.
5162 * Implemented INVITE command on client and server. The command
5163 were re-defined in the SILC Protocol Specification and the
5164 implementation now complies with the specification.
5166 * Implemented PING command on client and server.
5168 * Implemented NAMES command on client and server. The server side
5169 supports currently only normal server not router server yet.
5170 Some changes to NAMES definition in SILC protocol specification.
5172 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Implemented LEAVE command on client and server.
5176 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5177 again. This change was made to the protocol as well. Server
5178 should not violate the protocol specification anymore.
5180 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5183 was tested. SOCKS4 was not but should work anyway.
