1 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
5 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
7 * Removed channel key rekey task deleting from the function
8 silc_server_save_channel_key. Affected file silcd/server.c.
9 Added explicit timeout task context instead that is used to
10 delete the task if we are registering a new task before the
13 * When channel key rekey occurs the client library now saves
14 the old channel key for a short period of time (10 seconds) and
15 is able to use it in case some is still sending channel
16 messages encrypted with the old key after the rekey. Affected
17 file lib/silcclient/[idlist.h|client_channel.c].
19 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Added check to the silc_server_new_id_real to not accept
22 new ID if it is the sender's own ID. Affected file is
23 silcd/packet_receive.c.
25 * Assure that we do not announce ourself or the one we've
26 sending our announcements when we're router and are announcing
27 servers to our primary router. Affected file silcd/server.c.
29 * Fixed silc_server_command_identify_check_client to assemble
30 correct WHOIS packet. It send corrupted WHOIS packet and
31 caused problem with router to router connections. Affected
34 Fixed also silc_server_command_whois_check the same way
35 as for the IDENTIFY command.
37 * Added new SilcIDListStatus to the server in the SilcIDListData
38 structure. The status now includes the current status of
39 the entry (like registered, resolved etc.). Affected file
40 silcd/idlist.[ch]. Defined a bunch of different status types
41 as well. This replaced the old boolean registered field as well.
43 Added resolve_cmd_ident field to the SilcClientEntry structure
44 too so that if the entry is for example being resolved so
45 another command may attach to the same pending command reply
46 without requiring to resolve the same entry again. This concept
47 should optimize the WHOIS and the IDENTIFY resolving under
48 heavy load by taking away unnecessary resolving for entries
49 that are being resolved already.
51 Added support for adding multiple pending commands for one
52 command idenfier. Affected file silcd/command[_reply].[ch].
54 * Fixed WHOIS and IDENTIFY save to remove the cache entry
55 before deleting the data. Otherwise the hash table will have
56 freed data in comparison functions. Affected file is
57 silcd/command_reply.c.
59 * Fixed silc_idlist_replace_client_id to add the new entry to
60 the cache with NULL nickname. Otherwise there will be invalid
61 memory as the nickname after the nickname is freed. Affected
62 file silcd/packet_receive.c.
64 * Fixed the silc_idlist_get_clients_by_hash. The entries was
65 saved into wrong slots because the previous number of entries
66 was not taken into account. Affected file silcd/idlist.c.
67 Fixed same thing in silc_idlist_get_clients_by_nickname too.
69 * If we are router and we receive JOIN notify to a channel that
70 does not have any users then notified client is marked as the
71 channel founder, as it is it. The affected file is
72 silcd/packet_receive.c
74 * Added to the extended hash table API's table_del_*ext functions
75 the destructor as argument too, so that the caller can decide
76 which destructor to use or whether to use destructor at all.
77 Affected file lib/silcutil/silchashtable.[ch].
79 * Fixed ID Cache purging. It actually deleted the entries from
80 the hash table after the data was freed. The hash table ended
81 up comparing freed memory. The affected file is
82 lib/silccore/silcidcache.c.
84 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
86 * Fixed Irssi SILC client's KILL command's HELP syntax.
88 * The USERS command now resolves the detailed user information
89 if the userinfo field is missing. Affected file is
90 lib/silcclient/command_reply.c.
92 * Do not print error in silc_file_read if the read file does
93 not exist. Just silently return NULL. Affected file is
94 lib/silcutil/silcutil.c.
96 * Fixed the silc_log_output to not wine about NULL filename
97 and to not create some bogus " " filename. Affected file is
98 lib/silcutil/silclog.c.
100 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Fixed various printing bugs on the user interface in the
103 Irssi SILC Client. Minor changes that were forgotten from
106 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
108 * Fixed the configure.in.pre and the compilation and distribution
109 environment to support the new autoconf 2.52. That version is
110 now required to compile the CVS trunk.
112 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
114 * Renamed function silc_parse_nickname to silc_parse_userfqdn
115 to generally parse user@fqdn format strings. Affected file
116 lib/silcutil/silcutil.c.
118 * Added nickname_format and nickname_force_format fields to the
119 SilcClientParams structure. The first one defines the format
120 for the nicknames that the library will enforce if the receives
121 multiple same nicknames. The second one is boolean value and
122 can be used to force the library to always enforce the format
123 to the nicknames regardles whether there are multiple nicknames
124 or not. This configurable formatting was employed to flexibly
125 support accessing multiple nicknames from the user interface.
126 The userinterface can now set the nicknames to what ever format
127 they prefer. Affected file lib/silcclient/silcapi.h.
129 Added function silc_client_nickname_format to the file
130 lib/silcclient/idlist.c. It performs the nickname formatting.
132 Added new field `hostname´ to the SilcClientEntry context.
133 It holds the hostname of the client. Affected file is
134 lib/silcclient/idlist.h.
136 * Irssi SILC Client sets the nicknames in nick@hostn format.
137 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
138 irssi/src/silc/core/silc-core.c.
140 The WHOIS printing now also shows both the real nickname and
141 the formatted nickname so that user knows how to access the
142 user if there are multiple same nicknames cached. Affected
143 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
144 printing formatting too to take the hostname now as a separate
145 argument. The Affected file is
146 irssi/src/fe-common/silc/modules-formats.[ch].
148 * Changed the silc_client_get_clients_local to accept the formatted
149 nickname as argument. It accepts the real nickname too but the
150 formatted nickname can be used to find the true entry from
151 multiple entries. Affected file lib/silcclient/silcapi.h and
152 lib/silcclient/idlist.c.
154 * Added nickname_format_parse field to the SilcClientParams.
155 It is a callback function provided by the application to parse
156 the nickname out of the formatted nickname string. The library
157 calls it to get the nickname from the formatted string. Since
158 the application generally knows better the format of the nickname
159 string it parses it instead of the library, even though library
160 encodes the formatted string. If the callback function is not
161 provided then the library will use the string as is. The
162 affected file is lib/silcclient/silcapi.h.
164 * All the nickname strings passed to the client library in
165 commands are now expected to be formatted nickname strings.
166 If the command does not support the formatted nickname string
167 it will assume that the sent string is the actual nickname.
168 Affected file lib/silcclient/command.c.
170 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
172 * Added public key authentication support to OPER and SILCOPER
173 commands in the client library. Affected file is
174 lib/silcclient/command.c.
176 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
178 * Changed the get_auth_methdod client operation to be asynchronous.
179 It can be async if the application resolves the authentication
180 method from the server during the negotiation. Added new
181 SilcGetAuthMeth completion callback that the application will
182 call after resolving the authentication method.
184 Added function silc_client_request_authentication_method that
185 the application can use to resolve the authentication method
186 from the server. Added also SilcConnectionAuthRequest callback
187 that the library will call after the server has replied. The
188 application can call this function if it does not know the
189 current authentication method.
191 Affected files are lib/silcclient/client.c and
192 lib/silcclient/silcapi.h.
194 * The Irssi SILC client now automatically resolves the authentication
195 method incase any configuration information is not present (and
196 currently there never is). The affected file is
197 irssi/src/silc/core/client_ops.c.
199 * Fixed public key authentication from the client library.
200 Affected file lib/silcclient/protocol.c. Changed also the
201 protocol specification about the public key authentication in
202 the connection authentication protocol. The actual data to be
203 signed is now computed with a hash function before signing.
205 * Fixed the public key authentication from the server as well.
206 Affected file silcd/protocol.c.
208 * Removed the mlock()'s from the memory allocation routines.
209 Affected file lib/silcutil/silcmemory.c. The ./configure does
210 not check anymore for the mlock(). Affected file is
213 * Fixed USERS command in server to allow the execution of the
214 command for private and secret channels if the client sending
215 the command is on the channel. Affected file silcd/command.c.
217 * Fixed silc_client_get_clients_local to return the clients
218 count correctly. It could return wrong value. Affected file
219 lib/silcclient/idlist.c.
221 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
223 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
224 types. The assembler optimizations seemed not to like 64-bit
225 data types. The assmebler optimizations thus are now enabled
226 also for BSD systems as opposed to only enable them for Linux.
228 * Do not check for threads at all on BSD systems. Affected
229 file configure.in.pre.
231 * Removed -n and -h options from the Irssi SILC Client since
232 they are not used in silc.
234 * Fixed the prime generation to assure that the first digit
235 of the generated random number is not zero since our conversion
236 routines does not like number strings that starts with zero
237 digit. If zero digit is seen the random number is regenerated.
238 This caused some corrupted RSA keys when the zero first digit
239 was met. Affected file lib/silcmath/silcprimegen.c.
241 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
243 * Fixed WIN32 configuration in the ./configure script.
244 Fixed to include xti.h on environments that has it.
245 Patches by Carsten Ilchmann and andrew.
247 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
249 * Changed the silc_id_create_client_id to be collision
250 resistant. It is now assured that there cannot be created
251 two same client ID's. I suspect that some weird bugs in
252 the server were actually caused by duplicate Client IDs.
253 Affected file silcd/serverid.[ch]. A router receiving
254 new ID now also assures and informs the sending server
255 if the ID caused collision.
257 * Changed the silc_id_create_channel_id to also assure that
258 there are no collisions.
260 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
262 * Statement about ignoring the Mutual Authentication flag when
263 performing rekey with PFS was a bit misleading. It is ignored
264 if it was set in the initial negotiation, it cannot be even
265 set in the rekey. Fixed in the ke-auth draft. Started the
266 new versions of the protocol drafts in the doc/.
268 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
270 * Fixed a bug in silc_client_command_identify_save when saving
271 new channel information. The channel name was no duplicated
272 and caused crash on exit. Affected file is
273 lib/silcclient/command_reply.c.
275 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Fixed the getkey command handling in the server. Send just
278 empty OK reply to the sender if the key could not be fetched
279 (but everything else was ok, like the key just was not available).
280 Changed the public key parameter to optional in the protocol
281 specs so that empty OK reply can be sent. Affected file
284 Added a message to Irssi SILC client to tell to user if the
285 server did not return a public key.
287 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
289 * Fixed a channel key regeneration bug. It registered new
290 timeout tasks exponentially until all system resources were
291 used. Affected file silcd/server.c.
293 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
295 * Added the SILC Document generator to the scripts/silcdoc.
296 It can be used to generate the Toolkit Reference Manual out
297 of the source tree. Internally it will also use the RoboDoc
298 generator now imported in util/robodoc.
300 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
302 * Added couple of return's in rekey protocol if error orccurred
303 during the protocol. The execution must be terminated.
304 Affected file silcd/protocol.c. Also, terminate the protocol
307 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
309 * The client's Client ID was created initally from the wrong
310 nickname (it could have been in format nick@host) in the
311 silc_server_new_client. Affected file silcd/packet_receive.c
313 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
315 * Added some SILC_LOG_ERROR's to various error conditions
316 if client could not be added to ID cache. Affected files
317 silcd/packet_receive.c and silcd/server.c.
319 * When client's sock->user_data is freed, NULL also the
320 client->router and client->connection pointers. Added check
321 for these pointers being NULL to various places around the
322 code. Affected file silcd/server.c.
324 * Added client->data.registered == TRUE checks to various
325 places around the code to assure that unregistered client's
326 are not handled when it is not allowed. Affected file
329 * Added `bool registered' fields to all
330 silc_idlist_[server|client]_get_* routines to indicate whether
331 the fetched client needs to be registered or not. Affected
332 file silcd/idlist.[ch].
334 * Add your own entry as registered to the ID cache in the
335 server. Affected file server.c.
337 * Fixed a bug in silc_server_new_server. The SilcServer was
338 set as the new server's context instead of SilcServerEntry.
339 This naturally caused some weird bugs.
341 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
343 * Do not delete the channel rekey task when adding it
344 for in silc_server_create_channel_key.
346 * Changed the silc_server_create_channel_key to return
347 TRUE or FALSE to indicate the success of the channel key
350 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
352 * Fixed MSVC++ project files and added missing files to
353 Makefiles under win32/.
355 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
357 * Do not add TCP_NODELAY flag if the operating system
358 does not have it defined. Affected files are
359 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
361 * Fixed buffer overflow from Irssi SILC Client. Affected
362 file irssi/src/fe-common/core/themes.c.
364 * Fixed double free in client library in the file
365 lib/silcclient/client.c when disconnecting from server.
367 * Applied double free patch from cras to Irssi SILC client.
368 Affected files irssi/src/core/[modules/expandos].c
370 * Fixed the disconnection handling to Irssi SILC Client.
371 The application must call silc_client_close_connection
372 in ops->connect client operation in case of failure of
373 the connection. Affected file is
374 irssi/src/silc/core/client_ops.c.
376 * Do not set sock->protocol to NULL in the function
377 silc_client_close_connection after executing the protocol's
378 final callback since the sock might not be valid anymore.
379 Affected file lib/silcclient/client.c.
381 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
383 * Do not enable SILC_THREADS if the linking with libpthread
384 did not happen. Affected file configure.in.pre.
386 * Added notion to protocol specification that server must
387 verify the sent authentication payload with CMODE when
388 setting the channel founder key. Implemented it to the
389 server. Affected file silcd/command.c.
391 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
393 * Added _EXTRA_DIST SILC distribution variable to the
394 distributions file. It is used to conditionally add extra
395 files or directories to the specific distribution. Affected
396 files ./prepare, Makefile.am.pre and distributions.
398 Removed the `_' from the start of the distribution names.
401 * Added README.WIN32 for instructions to compile the Toolkit
404 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
406 * Fixed a double free in disconnection in the server. Affected
407 file is silcd/server.c.
409 * Fixed the lib/silcske/groups.c to work now also with GMP
410 MP library. The string conversion did not work when using
411 specific base and the base is indicated in the string as well.
413 * Created win32/ directory which now includes MSVC++ specific
414 stuff so that toolkit (DLLs) may be compiled with MSVC++.
415 It will appear only in the toolkit distribution
417 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
419 * Changed the key material distribution function in case when
420 the hash output is too short. The data is now concatenated
421 a bit differently than it used to. Made the change to the
422 SKE protocol specification.
424 * Added better GMP detection to configure.in.pre. A patch
427 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Fixed a minor bug in SKE that might cause some problem on
430 some platforms. Affected file lib/silcske/silcske.c.
432 * Added the cookie checking for initiator in the SKE. It checks
433 that the responder returns the sent cookie unmodified. The
434 affected file is lib/silcske/silcske.c. Added new SKE
435 error type INVALID_COOKIE that can be sent during the
436 negotiation. Fixed some memory leaks as well.
438 * Added the "invalid cookie" error message to Irssi SILC client's
441 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
443 * Added `task_max' field to the SilcClientParams to indicate
444 the maximum tasks the scheduler can handle. If set to zero,
445 default values are used. Affected file lib/silcclient/silcapi.h.
447 * Fixed memory leaks in silc_client_close_connection. Affected
448 file lib/silcclient/client.c.
450 * Added silc_client_del_client_entry to client library to free
451 all memory of given client entry. Affected file is
452 lib/silcclient/idlist.[ch].
454 * Added new functions silc_client_del_channel and
455 silc_client_del_server to delete channel and server entries.
456 Affected file lib/silcclient/[silcapi.h/idlist.c].
458 * Removed silc_client_del_client_by_id from silcapi.h.
460 * Fixed the INFO command to return the server's own info
461 correctly when querying by Server ID. Affected file is
464 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
466 * Removed the non-blocking settings in WIN32 code in the
467 silc_sock_[read/write] and added SleepEx instead. Affected
468 file lib/silcutil/win32/silcwin32sockconn.c. The availability
469 of input data is now checked with FIONREAD and ioctlsocket.
471 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
473 * Call silc_schedule_task_del_by_context in the
474 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
475 Affected file lib/silccore/silcprotocol.c.
477 * Call silc_protocol_cancel for active protocols in the
478 silc_server_close_connection if the funtion
479 silc_server_free_sock_user_data has not been called.
480 Affected file silcd/server.c.
482 * Generic tasks cannot be deleted using the del_by_fd
483 task deleting function since generic tasks does not match
484 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
486 * Added a notion to SILCOPER help file that the SILCOPER works
487 only on router server, not on normal server.
489 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
491 * Added for WIN32 support for the new scheduler as well.
492 Affected file lib/silcutil/win32/silcwin32schedule.c.
494 * Fixed the SHA1 implementation to work on various platforms.
496 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
498 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
499 API. It is part of the scheduler now. Everything else is
500 as previously but some functions has changed their names.
501 Checkout the lib/silcutil/silcschedule.h for the interface.
502 Updated all applications to use the new interface. Affected
503 files are lib/silcutil/silcschedule.[ch].
505 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Found a bug in the SKE implementation. The HASH value,
508 specified by the protocol, was not computed correctly. The
509 public key of the responder was not added to the computation
510 even though it is mandatory. Affected file lib/silcske/silcske.c.
511 This unfortunately causes incompatibilities with older
514 * Added WIN32 specific network init and uninit functions:
515 silc_net_win32_init and silc_net_win32_uninit to init and uninit
516 the Winsock2. Affected file lib/silcutil/silcnet.h and
517 lib/silcutil/win32/silcwin32net.c.
519 * Set the socket always to nonblocking mode on WIN32 after
520 reading data or writing data. Affected file is
521 lib/silcutil/win32/silcwin32sockconn.c.
523 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Fixed various compilation problems under WIN32. Affected
526 files lib/silcutil/win32/silcwin32thread.c and
527 lib/silcutil/win32/silcwin32schedule.c.
529 * Removed all _internal.h #includes from public header
530 files. Internal headers must never be included from
533 Removed also the lib/silcske/payload_internal.h file.
535 * All include files that may be needed (public and some others
536 included by the public headers) by application developers are
537 now copied to the ./includes directory. It does not copy any
538 internal headers. Affected file Makefile.defines.pre and all
539 Makefile.am's under lib/ and subdirs.
541 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
543 * Do not change the ~/.silc directory's permissions automatically.
544 Affected file irssi/src/silc/core/clientutil.c.
546 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
548 * Do not cancel the protocol in silc_server_close_connection
549 it might cause recursion. Now cancelled in the function
550 silc_server_free_sock_user_data. Affected file silcd/server.c.
552 * Fixed the silc_server_remove_clients_by_server to regenerate
553 the channel keys correctly finally. Added also new function
554 silc_server_remove_clients_channels to actually do it.
555 Affected file silcd/server.c.
557 * Fixed the silc_server_new_channel to not crash by giving
558 wrong router to the new channel. Affected file is
559 silcd/packet_receive.c.
561 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
563 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
564 which is given as argument to the silc_client_alloc now.
565 It can be used to configure the client and set various parameters
566 that affect the function of the client.
568 * The USERS command in server did not check whether the channel
569 is private or secret. Affected file silcd/command.c.
571 * Added new argument to the USERS command in protocol specification.
572 The USERS command now can take the channel name as argument
573 as well. Added support for this in client and server and
574 updated the protocol specs.
576 * Completed the GETKEY command in client. It can be now used
577 to fetch also servers public key not only some clients.
578 Affected files lib/silcclient/command[_reply].c.
580 * Added silc_client_get_server to return server entry by the
581 server name. Affected files lib/silcclient/silcapi.h and
584 * Redefined the IDENTIFY command in protocol specification to be
585 more generic. It now can be used to query information about
586 any entity in the SILC Network, including clients, servers and
587 channels. The query may be based either the entity's name
588 or the ID. Added support for this in both client and server.
590 Affected files silcd/command.c and lib/silcclient/command.c
593 * Optimized the WHOIS and WHOWAS commands in the server. Removed
594 the _from_client and _from_server functions. Affected file
597 * Added silc_client_get_channel_by_id_resolve to the file
598 lib/silcclient/silcapi.h to resolve channel information by
599 its ID. Added also silc_client_get_channel_by_id that
600 does not resolve it from the server.
602 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Added SilcServerEntry context into the client library
605 to represent one server. The INFO command now allocates
606 these to save the resolved server info. For now on the
607 client library will also keep information about servers,
608 connected and resolved with INFO.
610 The INFO command now allocates the SilcServerEntry context
611 and saves the server info there. The COMMAND_REPLY in
612 the INFO now returns the parameters to application in
613 same order as defined in the protocol specification.
615 The entries are cached in the client->server_cache.
617 * The INFO command is now issued after received the Client ID
618 from the server. Affected file lib/silcclient/client.c.
620 * The CMODE_CHANGE notify may now return also an SilcServerEntry
621 to the application as the mode changer might be server.
622 It is guaranteed that NULL is not returned anymore to the
623 application. Affected file lib/silcclient/client_notify.c.
625 The ID Type is now also passed to the application so that
626 it can check whether the returned entry is SilcClientEntry
629 Added new function silc_client_get_server_by_id to return
630 the server entry by ID. Affected files are the
631 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
633 * Do not create the channel in the Irssi SILC Client when issuing
634 the JOIN command but when received the sucessful JOIN command
635 reply. Otherwise the channel might get created even though we
636 could not join it. The Affected file is
637 irssi/src/silc/core/[silc-channels.c/client_ops.c].
639 * Fixed a channel joining bug in router. The router must also
640 check the channel modes, invite and ban lists etc. when serving
641 the JOIN command sent by normal server. Affected file is
642 silcd/command.c. The router now resolves the client's
643 information from the server who sent the JOIN command if it
644 does not know it, and processes the JOIN command only after
647 * Changed the SilcCommandCb to take new argument; void *context2.
648 Affected file lib/silccore/silccommand.h
650 The second argument in the command callbacks in the server now
651 includes the SilcServerCommandReplyContext if the command was
652 called as pending command callback from the command reply.
653 Otherwise it is NULL. When called as pending the status of the
654 command reply will be checked and if it was erronous the
655 error will be sent to the original sender of the command.
656 This way the client always receives the error messages even
657 though the server was actually the one who received the error
658 when it resent the command to router, for example. Affected
659 files silcd/command[_reply].[ch].
661 * Fixed sending WHOWAS command's error message to client if
662 the requested client could not be found. It was missing.
665 * Changed the CMODE and CUMODE commands reply arguments in the
666 protocol specification. The Channel ID is now sent in both
667 of the commands to identify the channel. Implemented this
668 new feature to the client and server. Affected files
669 lib/silcclient/command_reply.c and silcd/command.c.
671 * Made better checks for invite and ban lists in the JOIN
672 command in server. Affected file silcd/command.c.
674 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
676 * The server now performs the incoming host IP/DNS lookup
677 using the silc_socket_host_lookup and thus does not block
678 the server anymore. Affected file silcd/server.c.
680 * Completed the multi-thread support for SILC Scheduler in
681 the lib/silcutil/silcschedule.c.
683 * Fixed the configure.in.pre to detect the pthread correctly
686 * Fixed a deadlock in silc_task_queue_wakeup in the file
687 lib/silcutil/silctask.c.
689 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
691 * Added new function silc_schedule_wakeup that is used in
692 multi-threaded environment to wakeup the main thread's
693 schduler. It needs to be used when a thread adds a new task
694 or removes a task from task queues. After waking up, the
695 scheduler will detect the task queue changes. If threads
696 support is not compiled in this function has no effect.
697 Implemented the wakeup mechanism to both Unix and WIN32
698 systems. Affected files are lib/silcutil/silcschedule.[ch],
699 lib/silcutil/unix/silcunixschedule.c and the
700 lib/silcutil/win32/silcwin32schedule.c.
702 * Added new function silc_task_queue_wakeup to wakeup the
703 scheduler by the specified task queue. Affected file
704 lib/silcutil/silctask.[ch].
706 * The silc_socket_host_lookup_start now wakes up the scheduler
707 after adding the timeout task. Affected file is
708 lib/silcutil/silcsockconn.c.
710 * The silc_socket_host_lookup is synchronous now if the threads
711 support is not compiled in. However, the callback is still
712 called asyncronously through the scheduler, anyway. Affected
713 file lib/silcutil/silcsockconn.c.
715 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
717 * Added new function silc_socket_host_lookup to perform
718 asynchronous IP and FQDN lookups for the socket connection.
719 Affected files lib/silcutil/silcsockconn.[ch].
721 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
723 * Added SILC_MUTEX_DEFINE to define the mutex on environments
724 that may or may not compile the mutex support in.
726 Changed the silc_mutex_alloc interface. It allocates the
727 mutex now to the sent pointer and returns TRUE or FALSE.
729 Affected file lib/silcutil/silcmutex.h.
731 * Wrote the SILC Task Queue interface to support multi-threads.
732 Affected file lib/silcutil/silctask.[ch].
734 * Wrote the SILC Scheduler to support multi-threads. Affected
735 file lib/silcutil/silcschedule.c.
737 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
739 * Implemented the SILC Mutex API and SILC Thread API for WIN32
740 in lib/silcutil/win32/.
742 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
744 * Defined SILC Mutex API and SILC Thread API and implemented
745 them for Unix. Affected files are
746 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
747 lib/silcutil/unix/silcunixmutex.c and
748 lib/silcutil/unix/silcunixthread.c.
750 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Fixed the silc_server_remove_clients_by_server's channel
753 key re-generation. The hash table handling was incorrect
754 and would not work with many channels. Affected file is
757 * Fixed some memory leaks around the server code.
759 * Rewrote the silc_server_get_users_on_channel to support IPv6
760 based Client ID's. Affected file silcd/server.c.
762 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
763 specification. However, a separate document must be written
764 to define the detailed signing procedure and the payload
765 associated with the flag. Defined the flag to the
766 lib/silccore/silcchannel.h as well.
768 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Changed the dynamic tables to static size tables in the
771 lib/silccrypt/silchmac.c.
773 * Removed GCC dependencies from the code. A patch by cras.
775 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
777 * Do not show the error "Error receiving packet bla bla"
778 in server if it really was not an error (-2 means that reading
779 is pending). Affected file silcd/server.c.
781 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Fixed a possible crash in silc_server_remove_clients_by_server
784 in silcd/server.c. Fixed there also some memory leaks.
786 * Fixed the silc_idlist_replace_client_id. It could replace
787 wrong key in the hash table. Affected file silcd/idlist.c.
789 * Do not check whether there are global users on the channel
790 if the channel->global_users is FALSE. Affected functions
791 silc_server_remove_from_one_channel and
792 silc_server_remove_from_channels in silcd/server.c. Also,
793 do not check if the removed client is local as we can be
794 sure that global client was not removed from the channel
795 and checking for global users is not needed.
797 * The silc_server_remove_clients_by_server now re-generates
798 the channel keys correctly for those channels that had
799 clients removed from them. Affected file silcd/server.c.
801 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
803 * Found the reason of random crashes in the server. We weren't
804 ignoring the SIGPIPE signal (which can be sent in write())
805 and it crashed the server. Affected file silcd/silcd.c.
807 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Assure that sock->user_data is not NULL in the function
810 silc_server_packet_send in silcd/packet_send.c.
812 * Disconnect the remote connection if it could not be added
813 to any ID lists in the server. The affected file is
816 * Check in silc_server_packet_send[_real/dest] that the
817 socket is not disconnecting and ignore the data if it is.
818 Affected file silcd/packet_send.c.
820 * Define inline to __inline on native WIN32 compilation.
821 Affected file includes/silcwin32.h.
823 * Added some explicit type casts for inline code since MSVC
824 require them. Affected files lib/silcutil/silcbuffer.h,
825 lib/trq/silcdlist.h and lib/trq/silclist.h.
827 * Print warning in log files from now on if the packet
828 decryption fails. Affected file silcd/server.c.
830 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Changed the `say' client operation's interface to accept
833 new `type' argument to indicate the type of the message sent
834 by the library. The application may filter the library's
835 messages according the type. The affected file is the
836 lib/silcclient/silcapi.h.
838 * Added two new functions to lib/silcclient/silcapi.h:
839 silc_client_del_client and silc_client_del_client_by_id.
840 Affected file lib/silcclient/idlist.c.
842 * Moved the clientincludes.h from includes/ to silc/ and
843 serverincludes.h from includes/ to silcd/.
845 * The modes for the CMODE and CUMODE are now passed as
846 uint32 for application with COMMAND_REPLY. The affected
847 file is lib/silcclient/command_reply.c.
849 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
851 * /WHOIS without arguments shows client's own information.
852 Affected file lib/silcclient/command.c.
854 * Changed PING to not accept any arguments. The specs
855 says that client can ping only the connected server so
856 requiring an argument is not needed. Affected file is
857 lib/silcclient/command.c.
859 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
861 * Fixed a fatal bug in private message sending and reception
862 encryption and decryption when using private message keys.
863 The implementation was incorrect and did not follow the
864 specification. It causd that some of the message were
865 lost since it did not use the sending and receiving keys
866 as the protocol suggests. This has been fixed and will cause
867 incompatibilities with older clients when sending private
868 message encrypted with private message keys. Affected files
869 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
870 and various other in Irssi SILC Client.
872 Added `responder' boolean argument to the functions
873 silc_client_add_private_message_key[_ske] to indicate when
874 the key is added as responder or initiator of the key
877 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
879 * Removed the silc_ske_check_version function and created
880 a SilcSKECheckVersion callback. Added also a function
881 silc_ske_set_callbacks that is now used to set all SKE
882 callbacks. The callback functions are not given to
883 the SKE functions anymore, but this function is used to
886 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
888 * Added `silc_version' argument to the silc_client_alloc
889 to define the version of the application for the library.
890 The library will use the version string to compare it
891 against the remote host's (usually a server) version
892 string. Affected file lib/silcclient/silcapi.h
894 * Added the KE protocol context to Key Agreement context
895 in client library so that we can abort the SKE if it
896 is in process when we get timeout. Affected file is
897 lib/silcclient/client_keyagr.c.
899 * Do not resolve the client ID forever if it returns in the
900 first time that such client does not exist. This was done
901 for example with private message. Affected file is
902 lib/silcclient/client_prvmsg.c.
904 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
906 * Do not add regex.h for WIN32. The affected file
907 includes/silcincludes.h.
909 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
910 not work yet 100%. It generates the DLL's automatically
911 when compiling with --with-win32 under cygwin.
913 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
915 * lib/contrib/regex.c is not compiled on WIN32.
917 * Added silc_net_get_socket_opt function to the
918 lib/silcutil/silcnet.h.
920 * Added includes/silcwin32.h for WIN32 specific includes
923 * Do not use ptime structure or any of the posix process
924 functions on WIN32 in lib/silccrypt/silrng.c.
926 * Added silc_gettimeofday to provide generic function
927 for struct timeval on all platforms. Added the function
928 to lib/silcutil/silcutil.h.
930 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
932 * Moved the lib/silccore/silcsockconn.[ch] to the utility
933 library as they clearly belong there. As a plus side we
934 can make the actual socket connection routines platform
937 Added also new generic function silc_socket_read and
938 silc_socket_write (that used to be silc_packet_[read/write].
939 The implementation of these are platform specific.
941 * Added WIN32 specific routines of silc_socket_[read/write]
942 to lib/silcutil/win32/silcwin32sockconn.c.
944 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Added preliminary support for native WIN32 compilation under
947 cygwin (using the -mno-cygwin option for GCC) to the
948 ./configure.in.pre. The --with-win32 now prepares the
949 compilation for native WIN32.
951 * Rewrote the SILC Scheduler interface in the file
952 lib/silcutil/silcschedule.h. The scheduler is now context
953 based and does not have anymore any global static scheduler.
954 Moved the Unix scheduler to the lib/silcutil/unix/ directory
955 and created lib/silcutil/win32 directory for WIN32 based
958 * Added Unix specific network routines to the
959 lib/silcutil/unix/silcunixnet.c and the old
960 lib/silcutil/silcnet.c includes now only generic routines.
962 Added WIN32 specific network routines to the
963 lib/silcutil/win32/silcwin32net.c.
965 * Added Unix specific utility functions from the
966 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
968 * Added WIN32 SILC Scheduler to the file
969 lib/silcutil/win32/silcwin32schedule.c. The code is of course
972 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
974 * Do not handle JOIN notify in the server if the target client
975 is not registered (idata->registered == FALSE). The affected
976 file is silcd/packet_receive.c.
978 * Update the nickrec->founder in event_cumode in the Irssi SILC
979 client. Affected file irssi/src/silc/core/silc-channels.c.
981 * Fixed the CUMODE_CHANGE notify handling in the server when
982 server and router are announcing their clients on channels.
983 Now the mode changes are saved and notified correctly. The
984 affected file is /silcd/packet_receive.c.
986 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
987 They really did not replace the cache entry in the ID Cache.
988 Now they do that. Affected file silcd/idlist.c.
990 * Fixed the KICK notify handling in the Irssi SILC client to
991 update the channel records so that the kicked client does not
992 appear to be on the channel. The affected file is
993 irssi/src/silc/core/silc-channels.c.
995 * Always update the conn->current_channel when executing command
996 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
998 * Fixed the KILL notify handling in Irssi SILC client to remove
999 the killed client on all channels.
1001 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Fixed the silc_parse_command_line to remove extra spaces
1004 from the start and end of the arguments. Affected file is
1005 lib/silcutil/silcutil.c.
1007 * Cancel and free any active protocol in the function
1008 silc_server_close_connection. Affected file silcd/server.c.
1010 * Cancel and free any active protocol in the function
1011 silc_client_close_connction. Affected file is
1012 lib/silcclient/client.c.
1014 * Do not execute the KILL command for clients that are in
1015 history (ie. they are not in the network). Affected file is
1018 * Fixed KILL notify handling, client does not crash anymore.
1019 Affected file irssi/src/silc/core/silc-channels.c.
1021 * Reduced the default packet buffer size from 2048 to 1024 in
1022 lib/silccore/silcpacket.c.
1024 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1025 counter to the SKE context that is incresed when the SKE library
1026 performs async operation outside the library. If the outside
1027 process frees the SKE context and FREED status will be set
1028 and the library will detect after the sync operation that the
1029 libary is freed. The affected files are
1030 lib/silcske/silcske[_status].[ch].
1032 * Resolve the client entry information in the function
1033 silc_client_channel_message to assure that NULL pointer is not
1034 passed as client entry to the application. */
1036 * Fixed the task timeout calculation to assure that there is
1037 never negative timeouts. The affected file is
1038 lib/silcutil/silcschedule.c.
1040 * Fixed the channel user mode notification sending in server.
1041 It was sent point-to-point to the router (or to server by router)
1042 but it needs to be destined to a channel. The routines now
1043 supports sending the channel user mode notifys to the channels
1044 when announcing clients and channels. Affected files are
1045 silcd/server.c and silcd/packet_receive.c.
1047 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1048 It did not actually replace the old channel entry in the cache.
1049 Affected file lib/silcclient/client_notify.c.
1051 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Fixed a possible crash in silc_packet_send_prepare. It now
1054 assures always that there is enough space in the buffer and
1055 at the tail area of the buffer (for MAC).
1057 Fixed the inbound buffer reallocation in silc_packet_read.
1058 It was old code and did not handle the reallocation correctly.
1061 The affected file is lib/silccore/silcpacket.c.
1063 * Fixed buffer overflow in silc_parse_nickname in the file
1064 lib/silcutil/silcutil.c.
1066 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * make install generates new server keys only if there is not
1071 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1074 Added check that if the NOREPLY is set then we will not send
1075 the away message. This avoids infinite loop of away messages
1076 if both clients are away. The affected file is
1077 lib/silcclient/client_prvmsg.c.
1079 * Fixed client crash if /NICK was given without arguments.
1080 Affected file lib/silcclient/command.c.
1082 * Server does not send the invite list in INVITE command back
1083 to the client if the list was not altered. Added this notion
1084 to the protocol spec as well. Affected file silcd/command.c.
1086 Fixed possible crash in INVITE command by checking the
1087 value of silc_server_get_client_route command.
1089 * Fixed the INVITE notify type handling. The arguments are now
1090 taken in correct order and client does not crash. The affected
1091 file is irssi/src/silc/core/silc-channels.c.
1093 Removed the "Inviting xxx to channel" message from the
1094 client library away and let the application handle it.
1095 Affected file lib/silcclient/command.c. Added that message
1096 to Irssi SILC client's message formats.
1098 * Fixed CMODE command crash in client. It now checks the
1099 amount of arguments correctly and does not crash. The affected
1100 file is lib/silcclient/command.c.
1102 * Do not create new channel automatically in silc_channels_join
1103 but check whether the channel by that name already exists.
1104 Affected file irssi/silc/core/silc-channels.c.
1106 * Do not send the SERVER_SIGNOFF to router if the disconnected
1107 entity was the router. Affected file silcd/server.c.
1109 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1110 SILC client as it was missing from there.
1112 Added the handling of the KICK notify to the Irssi SILC client
1113 as it was missing. Added "you have been kicked" message to
1114 Irssi SILC client's message modules formats.
1116 Added the handing of the KILL notify to the Irssi SILC client
1117 as it was missing. Added the kill message module formats
1120 The affected file is irssi/src/silc/core/silc-channels.c.
1122 * The router did not save the channel mode the server announced.
1123 Affected file silcd/packet_receive.c.
1125 * Fixed a possible crash in INFO command in server. If the
1126 server did not provide the server info it crashed. Affected
1127 file silcd/command.c.
1129 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Fixed the GETKEY command in the server to check also the
1132 global list. Otherwise the GETKEY would not work correctly
1133 in normal SILC server. Affected file silcd/command.c.
1135 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Fixed GETKEY crash, it crashed if the command did not succseed.
1139 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1142 is now real and not just an macro interface to GMP.
1144 Removed the entire GMP from the source tree and imported new
1145 NSS MPI library instead. Reason for removing GMP is that it is
1146 extremely large and compiles extremely slow. The NSS MPI
1147 is only a few files and compiles in less than 10 seconds.
1148 The speed is also about the same as GMP. The MPI is imported
1149 to lib/silcmath/mpi.
1151 If the system has GMP installed we will still use the GMP.
1152 If it is not then the NSS MPI will be compiled.
1154 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Merged a long nickname (127 characters long) crash bugfix from
1157 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1159 * Merged a freed memory reference bugfix from Irssi CVS tree.
1160 Affected file irssi/src/core/commands.c.
1162 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Added the server's public key sving and verification to the
1165 server when performing the SKE. This was missing and the
1166 remote server's (or router's) public key was accepted without
1167 checking whether we have it previously or trust it at all.
1168 Affected file silcd/protocol.c.
1170 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Check in the silc_server_timeout_remote if protocol is active
1173 and make sure that the protocol's final callback is called so
1174 that all memory if freed. Affected file silcd/server.c.
1176 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * silc_server_whois_send_reply crashed the server if the nickname
1179 was 127 characters long. Affected file silcd/command.c.
1181 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Added sanity check to the silc_server_new_client. If the hostname
1184 is provided inside username then check that the provided hostname
1185 really is the same as the resolved one. If the hostname was not
1186 resolved then check it from the public key. Affected file is
1187 silcd/packet_receive.c.
1189 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1190 if the server disconnected us and the connection is not valid
1191 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1193 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1194 the library to the lib/silcutil/silcutil.[ch].
1196 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1198 * Close log file after open. Affected file
1199 lib/silcutil/silclog.c.
1201 * Check whether sock == NULL in silc_client_send_packet and return
1202 if it is. Affected file lib/silcclient/silcclient.c.
1204 * Check rec->entry == NULL in the Irssi SILC Client before
1205 sending the channel message. Affecte file is
1206 irssi/src/silc/core/silc-servers.c.
1208 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Merged a splitted window bugfix from Irssi CVS tree. The
1211 affected file is irssi/src/fe-text/textbuffer-view.c.
1213 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1214 It did not print nickname.
1216 * Improved the distributions system a bit.
1218 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1221 irssi/src/fe-text/gui-window.c.
1223 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1224 to in-active server. The affected file is
1225 irssi/src/silc/core/client_ops.c.
1227 * Resolve the client in USERS command reply if the entry does
1228 not have username resolved. The affected file is
1229 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1230 command to WHOIS command to really resolve stuff. The USERS
1231 is not used any more in any critical section so WHOIS can
1232 be used even though it might be slower than IDENTIFY.
1234 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1237 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Changed the protocol API a bit more consistent in the
1240 lib/silccore/silcprotocol.[ch].
1242 * Changed the following headers to ROBODoc format:
1244 lib/silccore/silcpayload.h
1245 lib/silccore/silcprotocol.h
1246 lib/silccore/silcsockconn.h
1248 All core library headers are now formatted.
1250 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Fixed a bug in Irssi SILC client; do not show that you are
1253 server/router operator if you really are not. Affected file is
1254 irssi/src/silc/core/client_ops.c.
1256 * Renamed silc_command_free_payload to silc_command_payload_free.
1257 Affected file lib/silccore/silccommand.h
1259 * Added silcmath.h to include the prototoypes of various routines
1260 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1263 * Changed the following headers to ROBODoc format:
1265 lib/silccore/silcchannel.h
1266 lib/silccore/silccommand.h
1267 lib/silccore/silcid.h
1268 lib/silccore/silcidcache.h
1269 lib/silccore/silcmode.h
1270 lib/silccore/silcnotify.h
1271 lib/silccore/silcpacket.h
1272 lib/silcmath/silcmath.h
1274 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1276 * Added checking to the server code not to start the server if
1277 ciphers and stuff are not configured properly. Affected files
1278 silcd/serverconfig.[h] and silcd/server.c.
1280 * Changed the layout of the header files of the public interfaces
1281 in the SILC libraries. The new layout supports ROBODoc
1282 documentation tool (and some others) so that it is easy to create
1283 a library reference manual. All the other headers and source
1284 code must still follow the CodingStyle document. Also source
1285 code must not include these ROBODoc stuffs, only the headers.
1286 Furthermore, all public interface headers must now be named
1287 by using `silc' prefix, example: silcapi.h, silccipher.h.
1288 Some files were renamed due to this. All the other headers
1289 must not be used as public interfaces. I will update the
1290 CodingStyle document later. Changed following headers, so far:
1292 lib/silcclient/silcapi.h
1293 lib/silccore/silcauth.h
1294 lib/silccore/silcprivate.h
1295 lib/silccrypt/silcdh.h
1297 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Removed silc_client_packet_send_flush from the client library
1302 as it is not needed. Affected file lib/silcclient/client.[ch].
1304 * Added printing of message of unresolved authentication method
1305 to the Irssi SILC client. Added it to the module formats.
1306 Removed the same message from the client library.
1308 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Added new distribution feature, DISTLABEL. Every distribution
1311 can define own preprocessor label that can be used in the
1312 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1313 file distributions, acconfig.h.pre and prepare.
1315 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * Added Makefile.defines_int to include the actual definitions
1318 for Makefile.defines.in. Tested the new distribution system,
1319 created distributions and tested installation.
1321 * Added AWAY message printing to the Irssi SILC client. Added
1322 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1324 * Added SCONNECT command to call the SILC's CONNECT command.
1325 Cannot use CONNECT directly since Irssi uses that internally.
1326 Affected file irssi/src/silc/core/silc-servers.c.
1328 Added ACTION local command. It is same as ME command but takes
1329 the channel as mandatory argument.
1331 Rewrote some of the Irssi's help files to suite for SILC
1334 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Added Makefile.defines[.in] that should for now on be included
1337 in all Makefile.am file in the source tree. That file includes
1338 all common compilation definitions for SILC source tree.
1340 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Minor changes to the ./prepare script to change the package
1343 name according the distribution name to the configure.in.
1345 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Created new distribution system. Added file `distributions'
1348 that defines all the distributions that can be created out of
1349 the SILC source tree. The ./prepare script now reads that
1350 file to determine how to prepare the distributions. The
1351 first argument to the ./prepare is the name of the distribution
1352 and second is the version of the distribution. If given
1353 without arguments it creates the default (toolkit) distribution
1354 with the default version (defined in ./prepare).
1356 All Makefile.am files that are subject to the distributions
1357 are now named as Makefile.am.pre. These are ./Makefile.am
1358 and lib/Makefile.am. Others may be changed later.
1360 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1362 * Added invite list, ban list, some key management and connection
1363 error message printing to module formats in the Irssi SILC client.
1365 * Added new silc_client_set_away_message to set the away message
1366 that is back to the person who sent private message. The
1367 affected file lib/silcclient/silcapi.h and the
1368 lib/silcclient/client_prvmsg.c.
1370 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1372 * Fixed the private message sending in the Irssi SILC client,
1373 added local command KEY to the Irssi SILC client.
1375 Added key management and key agreement message formats to the
1376 irssi/src/fe-common/silc/module-formats.[ch].
1378 Added USERS (alias WHO) printing, server/router operator
1379 indication and LIST command printing to the module formats.
1381 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Fixed channel joining notify handling, cumode notify handling
1384 from Irssi SILC client.
1386 * Added SILC specific module-formats to the Irssi SILC client so
1387 that SILC specific message hilighting, colors etc is possible.
1388 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1390 Added channel mode, channel user mode, actions, notices,
1391 whois and whowas printing to the the module-formats.c.
1393 * Fixed a bug in channel deletion in the server. The channel
1394 is not left to the cache even if the channel founder auth mode
1395 is set when there are no users anymore on the channel. Affected
1396 file silcd/server.c.
1398 * The silc_net_localhost now resolves the entire hostname including
1399 the domain name. Affected file lib/silcutil/silcnet.c.
1401 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Changed the ask_passphrase client operation to be ascynchronous.
1404 It has now a completion callback and a context that the
1405 application must call after it has got the passphrase from
1406 the user. Affected files lib/silcclient/silcapi.h,
1407 lib/silcclient/protocol.c, lib/silcclient/command.c and
1410 Added SilcAskPassphrase callback that the application calls
1411 to deliver the passphrase to the library.
1413 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1414 The public key verification and especially a certificate
1415 verification is asynchronous procedure.
1417 Added new SILC_SKE_STATUS_PENDING status to indicate the
1418 request is pending and a callback will be called to finalize
1421 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1422 indicate that remote end did not send its public key (or
1423 certificate), even though we require it. Added check for this
1424 condition in the SKE. This was a security bug, now fixed.
1426 Defined new SilcSKEVerifyCbCompletion callback that is called
1427 when the verification process is completed.
1429 The affected files lib/silcske/silcske_status.h and
1430 lib/silcske/silcske.[ch].
1432 * Changed the verify_public_key client operation to be async
1433 as well. Defined SilcVerifyPublicKey callback that is used to
1434 indicate the success of the public key verification process.
1436 Changed the server and client to use the new async client
1439 * Changed the Irssi SILC client's internal scheduler to be called
1440 twice as many times as it used to be. As a result the client
1441 should be a bit faster now. Affected file is
1442 irssi/src/silc/core/silc-core.c.
1444 * Added support to Irssi SILC client of asynchronous public key
1445 verification and passphrase inquiry. Affected file is
1446 irssi/src/silc/core/silc-core.c.
1448 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Do not say "You have left channel %s" in client library.
1451 Moved it to the application. Affected files are
1452 lib/silcclient/command.c and silc/client_ops.c.
1454 * Fixed silc_client_get_clients. Command context was not
1455 duplicated and was freed memory in the callback. Affected
1456 file lib/silcclient/idlist.c.
1458 * Do not say "you are now talking..." on JOIN command in the
1459 client library. The appliation must handle it.
1461 * Do not say ".. changed topic to" in command reply in the
1462 client libary. The application must handle it.
1464 * Fixed TOPIC command sending in the client library.
1466 * Fixed a memory leak in silc_client_command_free in the file
1467 lib/silcclient/command.c.
1469 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Imported a modified version of Irssi client to the source tree.
1472 The Irssi will be used to create a new client called
1473 Irssi SILC. Imported to irssi/.
1475 Added silc_core_init_finish function to the Irssi. Affected
1476 file irssi/configure.in.
1478 A lot changes in the Makefile.ams around the irssi tree.
1480 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Do not rehash if the new size is same as the old size of the
1483 hash table, in the silc_hash_table_rehash*. The affected file
1484 lib/silcutil/silchashtable.c.
1486 * Replaced hash_table_del_by_context calls from the server
1487 (when channel->user_list and client->channels) to the
1488 hash_table_del as it is sufficient and faster.
1490 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1492 * Added silc_hash_table_list, silc_hash_table_get and the
1493 SilcHashTableList structure to provide an alternative way to
1494 traverse the hash table. The affected files are
1495 lib/silcutil/silchashtable.[ch].
1497 * Changed the server's idlist routines to use the hash table
1498 routines to optimize the code.
1500 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Replaced the client entry's `channel' list and channel entry's
1503 `user_list' list to hash tables for optimized lookup. Changed
1504 the code to use the hash table interface around the code.
1505 Affected file lib/silcd/idlist.[ch].
1507 * Added `auto_rehash' boolean argument to the function
1508 silc_hash_table_alloc to indicate whether the hash table should
1509 auto-rehash when it thinks is appropriate time. It will
1510 increase the hash table size if the there is twice as much
1511 entries in the table than the size of the table, and will
1512 decrease the size if there are twice as less entries than
1513 the size of the table.
1515 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1519 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * silc_idcache_purge_by_context deletes the entry now by context
1522 as it is supposed to do. Affected file lib/silccore/idcache.c.
1524 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1525 client is not anymore valid (WHOWAS givens the info) and not
1526 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1528 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Removed the `data' and `data_len' arguments from the ID Cache
1531 interfaces and added `name' argument. ID Cache does not handle
1532 anymore the binary data only a names associated with given ID.
1534 * When hashing a Client ID with silc_hash_id the entire ID is
1535 not hashed anymore, instead only the hash of the Client ID is
1536 hashed. This way we can access the Client ID from the cache
1537 with Client ID but with the hash of the ID (which is a hash of
1538 the nickname) as well without any difference in performance.
1540 Added also silc_idcache_find_by_id_one_ext to do one on one
1541 searching when we have the actual ID. Added also function
1542 silc_hash_client_id_compare. The affected files are
1543 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1545 * When hashing the name associated with a ID it is always done
1546 in lowercase. This way we can access the cache without worrying
1547 about case-sensitivity, even though, for example nicknames are
1550 * Fixed a bug in server with channel message sending. It put
1551 wrong ID type as destination ID. The affected file
1552 silcd/packet_send.c.
1554 * silc_idcache_del_by_context now deletes from all hash tables
1555 by context. Affected file lib/silccore/idcache.c.
1557 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Changed the client library to use the new ID Cache interface.
1560 Changes around the source tree.
1562 * Added silc_hash_table_rehash_ext to rehash with specific
1563 hash function. Affected file lib/silcutil/silchashtable.[ch].
1565 * Added silc_hash_string_compare to compare two strings in the
1566 hash table. Affected file lib/silcutil/silcutil.[ch].
1568 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Added new function silc_idcache_del_by_context into the
1571 lib/silccore/idcache.[ch].
1573 * Changed the server's ID list routines to use the new ID Cache
1574 interface. Changes around the source tree.
1576 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Added silc_hash_table_del[_by_context]_ext functions in to the
1579 lib/silcutil/silchashtable.[ch].
1581 Removed silc_hash_table_find_all* routines and added new
1582 silc_hash_table_find_foreach to replace them.
1584 Added silc_hash_table_replace_ext function as extended
1585 replacing function. Separated the simple hash table interface
1586 from the extended hash table interface in the file
1587 lib/silcutil/silchashtable.h.
1589 * Fixed minor bugs and changed it to use some of the new
1590 hash table functions in lib/silccore/idcache.c
1592 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Added new function silc_hash_table_find_all to return all keys
1595 in the hash table by the specified key. As the hash table is
1596 collision resistant it also makes it possible to have several
1597 duplicate keys in the hash table. This function may be used to
1598 find all of the keys from the hash.
1600 Added user_context arguments to the SilcHashFunction,
1601 SilcHashCompare and SilcHashDestructor to deliver user specified
1604 Added new fuctions silc_hash_table_find[_all]_ext to do
1605 extended lookup with specified hash and compare functions and
1606 specified user contexts.
1608 Added new function silc_hash_table_add_ext to add the key
1609 with specified hash function and user context.
1611 Added new function silc_hash_table_foreach to traverse all
1612 entrys in the hash table. Added SilcHashForeach callback
1615 Added new function silc_hash_table_del_by_context to delete
1616 the entry only if the context associated with the key matches.
1618 Affected files are lib/silcutil/silchashtable.[ch].
1620 * Removed silc_hash_[server/client/channel]_id and added just
1621 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1622 silc_hash_id_compare to compare two ID's using as the hash table
1623 comparison function. Added also silc_hash_data to hash
1624 binary data and silc_hash_data_compare to compare it.
1626 * Removed silc_idlist_find_client_by_hash as it is not needed
1627 anymore. Affected file silcd/idlist.[ch].
1629 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1630 to use internally the SilcHashTable. The new ID Cache is a lot
1631 faster than the old one. Some of the ID Cache interface was also
1632 rewritten and obsolete and stupid functions were removed.
1634 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1636 * Added entry_count field to the SilcHashTable to keep the number
1637 of the entries in the table. Implemented the function
1638 silc_hash_table_rehash. Added new function
1639 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1641 Fixed a minor bug in silc_hash_table_free.
1643 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1644 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1645 into the lib/silcutil/silcutil.[ch].
1647 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Implemented a collision resistant hash table into the
1650 lib/silcutil/silchashtable[ch]. See the header and the source
1651 for the SilcHashTable API.
1653 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Merged dotconf version 1.0.2 into lib/dotconf.
1657 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * Do not compile anything in lib/silcsim/* if the SIM support
1660 is not enabled. The tree should now compile without problems
1663 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Compiled the SILC under cygwin. Compiled and tested briefly
1666 without problems. More tests needed. The SIMs didn't compile
1669 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1671 * Fixed possible crash in silc_get_username in the
1672 lib/silcutil/silcutil.c.
1674 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Fixed a va_arg in silc/client_ops.c.
1678 * Oops, RC5 routines were named AES and caused some problems
1679 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1681 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Added new SilcIDIP structure into the lib/silccore/id.h and
1684 replaced the old `ip' fields from all SILC ID's to that type.
1685 This is a step towards IPv6 support.
1687 The silc_id_get_len takes now the ID as an extra argument.
1688 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1689 both IPv4 and IPv6 based ID's.
1691 The affected files are lib/silccore/id.[ch] and other files
1692 around the tree using these routines.
1694 * Removed the ID length arguments in server from various
1695 silc_server_send_notify_* routines -> they are not needed
1698 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Fixed memory leak in silc_encode_pem_file in the file
1701 lib/silcutil/silcutil.c.
1703 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1705 * Check minor version as well in the SKE. Affected files are
1706 silcd/protocol.c and lib/silcclient/protocol.c.
1708 * Added --identifier option to the server so that an identifier
1709 can be when creating the public key for the server. Affected
1710 file is silcd/silcd.c.
1712 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1713 lib/silccrypt/silcpkcs.c.
1715 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1717 * Register default ciphers and stuff when using -C option with
1718 the server. Affected file sildc/silcd.c.
1720 * Put back the servers public key filename format, it is better
1721 than the new one. For now, the client keys are saved with the
1722 new filename format. The affected file silc/client_ops.c.
1724 * Implemented the Cipher API for the rest of the ciphers that
1725 did not implement it or implemented it the wrong way.
1727 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Register default ciphers and stuff when using the -S option
1730 in the client. Affected file silc/silc.c. Same also when
1731 creating new key pair with -C option.
1733 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Fixed the silc_verify_public_key client operation function to
1736 save the public keys differently. The fingerprint is now
1737 used as filename and not the hostname. This way also the
1738 client keys are saved uniquely and not with hostnames. The
1739 affected file is silc/client_ops.c.
1741 * Trimmed the silc_hash_fingerprint function to remove extra
1742 whitespaces from the end of the fingerprint. The affected
1743 file is lib/silccrypt/silchash.c.
1747 * Added silc_cipher_register_default function to register all
1748 default ciphers. It can be used when configuration files
1749 does not exist and the application does not want any specific
1750 ciphers in any specific order.
1752 The SilcDList is now used as silc_cipher_list dynamically
1753 allocated cipher list. Removed the static list all together
1754 and now all ciphers must be allocated to the dynamic list.
1755 The silc_cipher_alloc routine was changed to check only the
1758 All silc_cipher_* routines that used to return int returns
1761 The affected files lib/silccrypt/silccrypt.[ch].
1763 * The same thing was done to silc_hash_* as for silc_cipher_*
1764 routines. Affected files lib/silccrypt/silchash.[ch].
1766 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1767 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1768 Added also silc_pkcs_[un]register[_default] functions.
1769 Removed the data_context from the PKCS API.
1771 * Added silc_hmac_register_default function to register default
1772 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1773 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1774 to unregister all hmacs at once.
1776 * Register the default ciphers, hash functions, PKCSs and HMACs
1777 if client's configuration file does not exist. The affected
1780 * The client did not load the hash functions from the SIM
1781 modules at all. Added support for this. Affected file is
1782 silc/clientconfig.c.
1784 * When decoding public key with silc_pkcs_public_key_decode, check
1785 the supported algorithm only if PKCS are registered. Affected
1786 file lib/silccrypt/silcpkcs.c. The same was done with the
1787 silc_pkcs_private_key_decode.
1789 * Fixed the SILC List routines to keep the list always in order.
1790 It used to change the list's order when traversing the list but
1791 not it preserves the order. Affected file lib/trq/silclist.h.
1793 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1795 * Added the client library to use the SilcSocketConnection's
1796 reference counter (by silc_socket_dup) to prevent the bug that
1797 the socket object may be freed underneath async operation.
1799 * The name resolv library checking fixes in the configure.in.pre.
1802 * Created new version of the protocol drafts for future
1803 development. The -03 drafts are the ones that will be changed
1804 in the trunk now and the -02 will remain as they are.
1806 * Send list of CUMODE notifys to the router when announcing
1807 the channel users to the router. Affected file silcd/server.c.
1808 If the router receiving channel founder CUMODE for a channel
1809 that already has channel founder it will send CUMODE notify
1810 to the sender to remove the channel founder rights from the
1811 announced client. Affected file silcd/packet_receive.c.
1813 * The CUMODE notify may now use Server ID as well as the entity
1814 who changes the mode. Updated protocool specs.
1816 * Updated INSTALL and README files.
1818 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1820 * New web pages in the http://silc.pspt.fi. The pages was
1825 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * Implemented the [DenyConnectin] config section in the server.
1828 Added silc_server_config_denied_conn to check whether incoming
1829 connection is denied. Affected file silcd/serverconfig.[ch].
1831 * Do not check the ports when checking the incoming configuration
1832 data if the port is 0, meaning any. Affected file is
1833 silcd/serverconfig.c.
1835 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Fixed buffer overflow in silc_string_compare in the file
1838 lib/silcutil/silcutil.c.
1840 * Fixed double free in silc_server_command_leave in the file
1843 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Fixed the version checking in the server. Affected file is
1848 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Fixed the configuration data fetching when accepting new
1851 connections in the server. Affected file silcd/server.c.
1853 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Added `sender_entry' argument to the function
1856 silc_server_packet_relay_to_channel so that we can check
1857 whether some destination actually belongs to the same route
1858 the sender belongs (ie, we must not resend the packet to the
1859 sender). Affected file silcd/packet_send.[ch].
1861 * Added `servername' field to the SilcClientEntry in the server
1862 to hold the name of the server where client is from. Affected
1863 file is silcd/idlist.h.
1865 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Moved the channel message encrypting in the router betwen
1868 router connections from silc_server_channel_message to the
1869 silc_server_packet_relay_to_channel since we want to check
1870 whether we have anybody channel before encrypting anything.
1871 Affected files silcd/packet_[receive/send].c.
1873 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1875 * Fixed the [AdminConnection] server config section to support
1876 multiple entries. Affected file silcd/serverconfig.c.
1878 * Added support into the server to check the validity of the
1879 incoming connection before executing any KE or authentication
1882 * The connection configuration is now saved to the KE and
1883 connection auth protocol contexts and not fetched anymore in
1884 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1886 * The local hosts listenning address and port is also resolved
1887 now when starting the server. We want to have the socket object
1888 to include the real address and port for the listener. Added
1889 new function silc_net_check_local_by_sock into the files
1890 lib/silcutil/silcnet.[ch].
1892 * Fixed a broadcast bug in server -> do not broadcast if we
1895 * Fixed a routing bug. Do not route broadcast packets ever.
1896 Broadcast packets must be processed always and not routed since
1897 they may be destined to some other host than yourself and thus
1898 would get routed without no good reason. Affected file is
1901 * Added function silc_server_config_is_primary_route to check
1902 whether primary router connection has been configured (a router
1903 configuration that we are initiating). If there is not, we
1904 will assume that there is only two routers in the SILC network
1905 and we will use the incoming router connection as our primary
1906 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1908 * Changed the order of the broadcasting. Broadcast _after_ the
1909 packet has been processed not before. Affected file is
1912 * Fixed a [ClientConnection] parsing bug. The port was never
1913 parsed correctly thus resulting to port 0. Affected file
1914 silcd/serverconfig.c.
1916 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1917 argument and did not set the broadcast packet flag. Affected
1918 file silcd/packet_send.c. Fixed same bug in the function
1919 silc_server_send_notify as well.
1921 * If we receive NEW_ID packet for our own ID in the server, ignore
1924 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1928 * Removed the nickname from the Private Message Payload.
1929 Updated the code and the protocol specs.
1931 * Updated protocol specs for submitting to the IETF.
1933 * Tweaked the Random Number Generator a bit. Affected file
1934 lib/silccrypt/silcrng.c. Exported a new function
1935 silc_rng_[global]_add_noise which can be used to add more
1938 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Do not parse packets with different timeout when protocol
1941 is active -> may cause problem with rekey. Affected file
1944 * When server receives signoff notify it must not create
1945 new channel key if the client is on any channels since the
1946 sender of the signoff notify will create it.
1948 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Added printing of error messages during SKE protocol from the
1951 failure packet sent by server during SKE. Affected file
1954 * Removed the client's failure_callback handling with timeout
1955 and handle it immediately when received.
1957 * The SKE library returned wrong type in SUCCESS and FAILURE
1958 packets. They must be 32 bit MSB not 16 bit MSB.
1960 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Ok, rewrote the logic of the re-key and now it seems to work.
1963 I tested it on high traffic with frequent re-keys without
1964 problems. Added hmac_receive (and renamed hmac to hmac_send)
1965 in SilcClientConnection in lib/silcclient/client.h and
1966 in SilcIDListData in silcd/idlist.h. Also, removed the
1967 SilcPacketParserContext's cipher and hmac fields as they are
1968 not needed anymore and actually caused some problems when
1969 the ciphers and hmac's changed underneath the packet parser.
1971 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1973 * If re-key protocol is active then process the incoming packets
1974 synchronously since we must assure that icoming packets encrypted
1975 with the old key is processed before the new keys is set to
1976 use. This is true other packets than for REKEY packets.
1977 Affected file silcd/server.c. The same was done to client library
1978 as well, affected file lib/silcclient/client.c.
1980 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Fixed bug in client and server to accept the force send if
1983 the packet is send from silc_[server/client]_packet_process
1984 function. Otherwise the packets are never delivered, oops.
1986 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Disable force sending of packets when REKEY protocol is active.
1989 We must assure that no packet is sent directly when rekey is
1990 performed. All packets must be sent through packet queue.
1991 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1992 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1993 function is silc_[server/client]_packet_send_real to check
1996 * Replaced the SIM paths from example config files to
1997 /usr/local/modules. Also, make install creates now
1998 /usr/local/silc/logs directory to hold all the SILC server
2001 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2012 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * When MAC computation fails the silc_packet_decrypt returned 0
2015 even though it was supposed to return -1. Fixed this. The
2016 affected file is lib/silccore/silcpacket.c.
2018 * Do not replace the config files in /etc/silc (in make install)
2019 if they already exist. Affected file ./Makefile.am.
2021 * Do not send re-key packets immediately but through packet queue.
2022 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2024 * Changed silc_net_check_host_by_sock to return FALSE if the
2025 IP/DNS could not be resolved. Though, it returns the IP address
2026 now even if it could not resolve it (but returns also FALSE).
2027 Affected file lib/silcutil/silcnet.[ch].
2029 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Added silc_pkcs_decode_identifier to decode the public key's
2032 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2033 Added also silc_pkcs_free_identifier. Added also new context
2034 SilcPublicKeyIdentifier.
2036 * Added -S option to the silc client. It is used to dump the
2037 contents of the specified public key file.
2039 * Changed the PKCS api to return the public key length when
2040 setting the public key.
2042 * Fixed a fatal bug in the public and private key file loading.
2043 Affected file lib/silccrypt/silcpkcs.c.
2045 * Execute the packet parsing for client with zero (0) timeout
2046 if the protocol is active. Affected file silcd/server.c.
2048 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Made the key generation options to the silcd program. Added
2051 -C option, equivalent to client's option.
2053 * Added new [ServerKeys] config section to the server. It
2054 configures the server's public and private key.
2056 * Defined generic Public Key Payload into the protocol
2057 specification to send specific type of public keys and
2060 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2061 public key or certificate.
2063 * Implemented the GETKEY command to the server and to the
2064 client library and on user interface.
2066 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2097 SilcClientConnection structure; not needed. Affected file is
2098 lib/silcclient/client.h.
2102 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Do not ask whether user wants to use the negotiated private key
2105 for private messages, just use it. Affected file is
2106 silc/local_command.c.
2108 * Added `send_enc_key' and `enc_key_len' fields to the
2109 SilcIDListData structure since they are needed in the re-key

2133 * Changed _ALL_ unsigned long and unsigned int to uint32,
2134 unsgined short to uint16 in the source tree.
2136 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2137 not handle clients that has entry->data.registered == FALSE.
2138 They are not in the network anymore. Affected file is
2141 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2156 application. Affected file silc/client_ops.c.
2158 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2159 if the deleting was successful. Affected file silcd/idlist.[ch].
2161 * Added support for public key authentication in the connection
2162 authentication protocol in the client library. Affected file
2163 lib/silcclient/protocol.c.
2165 * Changed the server's silc_idlist_get_clients_by_* interface
2166 to support already allocated array so that new entries may be
2167 added to pre-allocated array. Affected file silcd/idlist.[ch].
2168 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2169 and command replies.
2171 * All command reply functions in the server now calls the
2172 pending command callback even if error occured. This way the
2173 error will be delivered to the client as well. Affected files
2174 silcd/command.c and silcd/command_reply.c.
2176 * Fixed INFO command to return local server's info if no server
2177 was provided. Affected file lib/silcclient/command.c.
2179 * Removed RESTART command for good. Updated the code and the
2182 * Rewrote parts of the task system. It is a bit simpler now.
2183 Removed unsued task priorities. The affected files are
2184 lib/silcutil/silctask.[ch].
2186 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Moved the USERS printing from the library to the application.
2189 Affected files lib/silcclient/command.c and silc/client_ops.c.
2191 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2195 * Added channel key re-key support. The re-key is perfomed
2196 only by the router and is done once in an hour. Added `rekey'
2197 field to the SilcChannelEntry in the server. Affected files
2198 silcd/server.c and silcd/idlist.h.
2200 * Added silc_task_unregister_by_context into the file
2201 lib/silcutil/silctask.[ch].
2203 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * Added SILC_UMODE_GONE mode to indicate when the client is not
2206 present in the SILC network. Added also support to the local
2207 command AWAY that will set this mode. Added support of showing
2208 "xxx is gone" in WHOIS command. The USERS command shows the
2209 gone status as well.
2211 * Fixed setting server and router operator privileges in the
2212 server's UMODE command. Affected file silcd/command.c.
2214 * Merged the SKE KE1 and KE2 payloads into one payload. The
2215 new KE payload is equivalent to the old KE2 payload.
2217 Cleaned up the SKE Start Payload parsing. It now uses the
2218 simple buffer unformatting to do the parsing. A lot faster
2221 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2222 to the SKE that is used to indicate whether both of the SKE
2223 parties should perform authentication. By default only the
2224 responder performs authentication. By setting this flag also
2225 the initiator must do authentication. By default it is unset
2226 since in normal SKE case, client to server connection, only
2227 the responder should do authentication. When doing SKE between
2228 two clients both should perform authentication. Updated the
2229 code and the protocol specs.
2231 * A little fix to IDENTIFY command in the server. Search the
2232 client first by hash not nickname. Affected file is
2235 * Fixed the silc_client_close_connection to support closing
2236 the client to client connections wihtout deleting too much
2237 data. Affected file lib/silcclient/client.c.
2239 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2240 are received if protocol used to be active but is not anymore
2241 the application would crash due to NULL pointer dereference.
2242 Affected files silcd/server.c and lib/silcclient/client.c.
2244 * Added `hash' field to the SilcClientConnection to include
2245 the hash function negotiated in the SKE protocol.
2247 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2248 to set the channel founder authentication data. A client can
2249 claim the founder rights later by providing the authentication
2250 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2251 This way the channel founder can regain the channel founder
2252 privileges even it is left the channel. This works only on
2253 local server and the client must be connected to the same
2254 server to be able to regain the founder rights. Updated the
2255 protocol specs accordingly.
2257 Added support to the CMODE command in the client to set the
2258 founder auth data. Read the README to see how to set it.
2260 Added support to the CUMODE command to claim the founder
2261 rights. Read the README to see how to do it.
2263 Added support for the founder authentication to the Channel
2264 Entry in the server. Affected file silcd/idlist.h.
2266 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2267 server's CMODE command. Affected file silcd/command.c.
2269 * Added the following new functions into lib/silccore/silcauth.[ch]:
2270 silc_auth_get_method and silc_auth_get_data.
2272 * The server now saves the remote hosts public key to the
2273 SilcIDListData pointer. Affected file silcd/protocol.c.
2275 * The normal server now does not remove the channel entry from
2276 the cache if the founder authentication data is set. It used
2277 to remove it if the founder was the last one on the channel on
2278 the server and left the channel. The auth data is saved and
2279 if the channel is re-joined later the old entry is used with
2280 the old auth data. Affected files silcd/command_reply.c and
2283 * Removed the `pkcs' field from the SilcIDListData structure
2284 in the server; it is not used. Affected file silcd/idlist.h.
2286 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Fixed packet processing on slow links. Partial packets were
2289 never re-processed because the incoming data buffer was cleared
2290 by the application. Application must not directly clear the
2291 sock->inbuf, the packet processing routines handle it. Fixed
2292 this in client library and in server.
2294 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Fixed the WHOIS and IDENTIFY send reply function to really
2297 check whether to send list or just one entry. Affected file
2300 * Cleaned up the LEAVE command's channel key distribution. The
2301 affected file silcd/command.c.
2303 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2304 can enforce the channel mode as well. In that case the ID
2305 includes the ID of the server. The code now enforces the
2306 mode change if the router have different mode than the server.
2308 * The notify client operation with CMODE_CHANGE notify can now
2309 return NULL client_entry pointer if the CMODE was not changed
2310 by client. Application must check for this.
2312 * Added <Server ID> argument to INFO command to support server
2313 info fetching by Server ID.
2315 * Added silc_server_announce_get_channel_users to get assembled
2316 packets of channel users of the specified channel. Affected
2317 file silcd/server.[ch].
2319 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2320 was freed underneath the ID Cache.
2322 * Re-announce clients when the server received CHANNEL_CHANGE
2323 notify from the router. Affected file silcd/packet_send.c.
2325 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2328 crashed since it did not handle the fact that there is no cipher
2329 called "3" and didn't check the error condition. Now fixed.
2331 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2332 flag. It can be used to send message requests.
2334 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2336 * Implemented the RESTART command in the client.
2338 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2339 notice type messages. Added notice printing to the user
2342 * The channel keys are not re-generated if the channel's mode
2343 is PRIVKEY, ie private key on the channel exists. Affected
2344 files silcd/server.c and silcd/command.c.
2346 * Fixed a little bug in channel message delivery when channel
2347 private keys are set in the server. Affected file is
2348 silcd/packet_send.c.
2350 * Changed the setting on channel->on_channel = TRUE from the
2351 silc_client_save_channel_key to the JOIN command reply. The
2352 key payload is not received if the private channel key is set.
2353 Affected file lib/silcclient/command_reply.c and the
2354 lib/silcclient/client_channel.c.
2356 * When the CMODE_CHANGE notify is sent and the channel private
2357 key mode is removed the channel key must be re-generated in
2358 other cells as well. Added this support for the router in the
2359 silcd/packet_receive.c.
2361 * Added new local command NOTICE to send notice message on
2362 channel. Affected file silc/local_command.[ch].
2364 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Added new local command ME to the client. It is used to send
2367 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2368 some action. Affected file silc/local_command.[ch].
2370 * Changed channel_message and private_message client operations
2371 to deliver the message flags to the application. Added also
2372 the `flags' arguments to the silc_client_send_channel_message
2373 and silc_client_send_private_message functions. Affected file
2376 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Redefined the Private Message Payload to support private message
2379 keys and to support the new private message flags. Updated
2380 the protocol specs. Flags makes it possible to have for example
2381 CTCP style messages.
2383 * Added new type SilcPrivateMessagePayload and defined an API
2384 for it in the lib/silcclient/silcprivate.[ch].
2386 * Tested private message private keys successfully. Tested the
2387 private message key set, unset and list commands with the new
2390 * Redefined the Channel Message Payload to include the channel
2391 message flags (equal with private message flags) to support
2392 for example CTCP style messages.
2394 * Defined some of the message (for channel and private message)
2395 flags. Updated the protocol specs and added the flags to the
2396 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2398 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2400 * Added SilcKeyAgreementStatus type to the key agreement routines
2401 to indicate the current status and error if one occured.
2402 The status types are defined in the lib/silcclient/silcapi.h.
2404 * Added new local command KEY that is used to set and unset private
2405 keys for channels, set and unset private keys for private messages
2406 with remote clients and to send key agreement requests and
2407 negotiate the key agreement protocol with remote client. The
2408 key agreement is supported only to negotiate private message keys,
2409 it currently cannot be used to negotiate private keys for channels,
2410 as it is not convenient for that purpose.
2412 * Fixed a minor pending callback setting bug in the function
2413 silc_client_get_client_by_id_resolve, now the function works.
2414 Affected file lib/silcclient/idlist.c.
2416 * Added function silc_net_get_local_port to get local bound
2417 port by socket. Added to lib/silcutil/silcnet.[ch].
2419 * Added `sockets' and `sockets_count' fields to the SilcClient
2420 object. They hold the sockets of the listenning sockets in
2421 the client. Listenning sockets may be for example the key
2422 agreement server. Affected file lib/silcclient/client.[ch].
2423 Added functions the silc_client_add_socket and the
2424 silc_client_del_socket. They are exported to the application
2427 * Added ~./silc/clientkeys to support other client's public keys.
2429 * Renamed verify_server_key client operation to verify_public_key
2430 and added one argument to indicate the type of the connection
2431 (server, client etc.).
2433 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Added silc_server_connection_auth_request to handle the
2436 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2437 silcd/packet_receive.[ch].
2439 * Added silc_server_send_connection_auth_request into the
2440 silcd/packet_send.c to send the connection auth request packet.
2442 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2445 * Fixed the public key authentication in responder side in the
2446 server. The `auth_data' pointer includes the SilcPublicKey
2447 not the path to the public key. Affected file silcd/protocol.c.
2449 * Implemented the public key authentication in the initiator side
2450 in the server. Affected file silcd/protocol.c.
2452 * Removed the [RedirectClient] config section from the server
2453 configuration. Is not needed and I don't want to implement it.
2455 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Cleaned up the CMODE command in the server. It now works
2458 correctly and supports all the modes defined in the protocol.
2459 Affected file is silcd/command.c.
2461 * Added `hmac_name' field to the SilcChannelEntry in the server
2462 to hold the default HMAC of the channel. It can be set when
2463 creating the channel (with JOIN command). Affected files
2466 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2467 type to indicate the change of the current cipher and hmac
2468 on the channel. Client can safely ignore the <cipher> argument
2469 (if it chooses to do so) since the CHANNEL_KEY packet will
2470 force the channel key change anyway. The <hmac> argument is
2471 important since the client is responsible of setting the new
2472 HMAC and the hmac key into use.
2474 * Fixed the CMODE command in the client library as well.
2476 * Tested CMODE command in router environment successfully.
2478 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Show the version of the remote client (or server) when connecting
2481 to the server. It is logged to the log file. Affected file
2482 is silcd/protocol.c.
2484 * Fixed the KILLED notify handling in the client library. The
2485 client must be removed from all channels when receiving the
2488 Also, do not remove the client entry when giving the KILL
2489 command but when the KILLED notify is received.
2491 * Removed silc_idlist_find_client_by_nickname from the server.
2492 Not needed anymore. Affected files silcd/idlist.[ch].
2494 * Implemented the CHANNEL_CHANGE notify type handling to the
2495 server. Affected file silcd/server.c.
2499 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Added silc_server_send_notify_invite to send the INVITE
2502 notify between routers.
2504 * Implemented the INVITE command correctly to the server.
2506 * Implemented the INVITE notify type handling in the server.
2508 * Implemented the INVITE command to the client library and on the
2511 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Added function silc_server_get_client_resolve to find the
2514 client entry by ID from all ID lists and then resolve it
2515 (using WHOIS) if it cannot be found. Affected file is
2518 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * Implemented the BAN command to the client library.
2522 * The JOIN command in the server now checks the invite list
2525 * Changed the silc_command_reply_payload_encode_va and the
2526 silc_command_payload_encode_va to support that if argument is
2527 NULL it ignores and checks the next argument. Affected file
2528 lib/silccore/silccommand.c.
2530 * Added silc_server_send_notify_ban to send the BAN notify
2531 type between routers.
2533 * Chaned the silc_notify_payload_encode to support that if
2534 argument is NULL it ignores and checks the next argument.
2535 Affected file lib/silccore/silcnotify.c.
2537 * Tested ban lists in router environment successfully.
2539 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2541 * Implemented BAN command to the server, in silcd/command.[ch].
2543 * Removed the BAN and INVITE_LIST modes from the CMODE command
2546 * Added function silc_string_match to regex match two strings.
2547 Affected files lib/silcutil/silcutil.[ch].
2549 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Redefined parts of the SilcChannelEntry in the server to support
2552 the new ban and invite lists.
2554 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Redefined the INVITE command. The same command can be used to
2557 invite individuals to the channel but also to manage the invite
2558 list of the channel (to add to and remove from the invite list).
2559 Updated the protocol specs.
2561 * Added new command SILC_COMMAND_BAN that can be used to manage
2562 the ban list of the channel. Updated the protocol specs.
2564 * Removed the channel modes: the SILC_CMODE_BAN and the
2565 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2566 in the CMODE command. The equivalent features are now available
2567 using INVITE and BAN commands. Updated the protocol specs.
2569 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2570 in the network about change in the current ban list. The notify
2571 type is not used by the client.
2573 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2574 support the invite lists.
2576 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Added new function silc_string_regexify that converts string
2579 including wildcard characters into regex string that can
2580 be used by the GNU regex library. Added into the file
2581 lib/silcutil/silcutil.[ch].
2583 Added silc_string_regex_combine to combine to regex strings
2584 into one so that they can be used as one regex string by
2585 the GNU regex library. Added into the file
2586 lib/silcutil/silcutil.[ch].
2588 Added silc_string_regex_match to match two strings. It returns
2589 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2591 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Imported GNU regex to the soruce tree into lib/contrib.
2594 Fixed some compiler warning from the regex.c.
2596 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Fixed MOTD command in the server to work in router environment.
2600 * Fixed the MOTD command in the client library to support
2601 the server argument in the command.
2603 * Added `nickname_len' argument to the silc_idlist_add_client
2604 in the server, as the `nickname' argument may be binary data
2607 * Added silc_idlist_get_channels to return all channels from
2610 * Implemented LIST command to the server. Affected file is
2613 * Implemented the LIST command to the client library and on the
2616 * Added [<user count>] argument to the LIST command reply.
2617 With private channels the user count is not shown.
2619 * Updated TODO and README.
2621 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * The client entry's data.registered must be TRUE even with
2624 global client entry on global client list. The data.registered
2625 is used to check whether the client is anymore in the network,
2626 for example with WHOWAS command so it must be valid.
2628 * Fixed the WHOWAS command in the server. It now actually works
2629 in router environment. Added function into silcd/command_reply.c
2630 silc_server_command_reply_whowas_save.
2632 * Added silc_idlist_purge function to the silcd/idlist.c
2633 to periodically purge the ID Cache.
2635 * Fixed INFO command in the server. It works now in router
2636 environment. Added <server name> argument to the INFO command
2637 reply. Updated the protocol specs.
2639 * Fixed minor bug in silc_idcache_purge to not purge if the
2640 expire value is zero.
2642 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2643 they were buggy because of the WHOWAS information.
2645 * Fixed local command MSG to handle the async resolving of
2646 the remote client properly. It used to fail the first MSG.
2647 Affected file silc/local_command.c.
2649 * Added `data_len' field to SilcIDCache context.
2651 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Update TODO. Todo in commands in the server.
2655 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2658 used by routers as broadcast packet to inform other routers
2659 about the changed user mode.
2661 Implemented the notify handling in the server. Affected file is
2662 silcd/packet_receive.c. Added the function
2663 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2665 * Added new generic Channel Payload and deprecated the New Channel
2666 Payload. The New Channel Payload is now the generic Channel
2669 * Added new argument `mode' to the silc_server_send_new_channel
2670 as it is required in the Channel Payload now.
2672 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2673 and created a new and real SilChannelPayload to represent the
2674 new generic Channel Payload. Implemented the encode/decode
2675 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2677 * Added silc_server_get_client_channel_list to return the list
2678 of channels the client has joined for WHOIS command reply.
2679 Affected file silcd/server.[ch].
2681 * Implemented the channel list sending in the WHOIS command reply
2682 in server and in the client.
2684 Implemented the channel list displaying on the user interface
2685 as well. Affected file silc/client_ops.c.
2687 * Added silc_channel_payload_parse_list to parse list of Channel
2688 Payloads. It returns SilcDList list of SilcChannelPayloads.
2689 Client for example can use this function to parse the list of
2690 channels it receives in the WHOIS command reply. The caller
2691 must free the list by calling silc_channel_payload_list_free.
2692 Affected files lib/silccore/silcchannel.[ch].
2694 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Added one new argument <user mode> to the WHOIS command reply
2697 to return the mode of the user in SILC. Updated the protocol
2700 Implemented it to the server and client.
2702 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * Fixed the mode printing on the user interface on joining.
2705 Affected file silc/client_ops.c.
2707 * Implemented the UMODE command and user modes in general to the
2708 client library and to the user interface.
2710 * Implemented the UMODE command to the server.
2712 * The server now sends UNKNOWN_COMMAND error status if client sends
2713 unknown command. Affected file silcd/command.c.
2715 * All server commands now handle the command identifier the right
2716 way when sending the command reply to the client. The client can
2717 use to identify the command replies with the identifier.
2719 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Added silc_server_get_client_route to resolve the route to
2722 the client indicated by the client ID. Affected file is
2725 * Added silc_server_relay_packet as general function to relay
2726 packet to arbitrary destination. This deprecates functions
2727 like _send_private_message_key, _relay_notify etc. Affected
2728 file is silcd/packet_send.[ch].
2730 Removed silc_server_send_key_agreement,
2731 silc_server_send_private_message_key and
2732 silc_server_packet_relay_notify functions from the file
2733 silcd/packet_send.[ch].
2737 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2738 server. Affected file silcd/packet_receive.[ch].
2740 * Implemented the KILL command to the client. Implemented the
2741 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2742 Affected files lib/silcclient/command[_reply].c and
2743 lib/silcclient/client_notify.c. Implemented the KILL notify
2744 printing in the user inteface.
2746 * Fixed a lot silc_parse_nick memory leaks from the client
2747 library in the file lib/silcclient/command.c.
2749 * Changed the silc_server_send_notify_on_channels's `sender'
2750 argument from SilcSocketConnection to SilcClientEntry to
2751 check the sender as entry and not as connection object and not
2752 to send to the client provided as argument. The affected file
2753 is silcd/packet_send.[ch].
2755 * The notify packets that are destined directly to the client used
2756 to not to be processed by the server. Now changed that and the
2757 server processes all notify packets. After relaying the packet
2758 to the client the notify packet is processed in the server.
2760 * The silc_server_free_client_data now checks whether there is
2761 pending outgoing traffic for the client and purges the data to
2762 the network before removing the client entry.
2764 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2767 an client is killed from the SILC Network. Updated the protocol
2770 Added new function silc_server_send_notify_killed to the
2771 silcd/packet_send.[ch].
2773 * Added function silc_server_packet_relay_notify to relay notify
2774 packets that are destined directly to a client. In this case
2775 the server does not process the notify packets but merely relays
2776 it to the client. Affected file silcd/packet_send.[ch].
2778 Added also silc_server_packet_process_relay_notify to check
2779 whereto relay the notify. Affected file is
2780 silcd/packet_receive.[ch].
2782 * Implemented the KILL command to the server.
2786 * Added the backup schema desgined last fall to the protocol
2787 specs for everyone to see. The specification is in the
2788 *-spec-xx.txt draft and the packet type definitions for the
2789 backup routers is in *-pp-xx.txt draft. Thusly, added also
2790 new packet type SILC_PACKET_CELL_ROUTERS.
2792 * A big security problem in the implementation discovered. The
2793 signoff of an client did not cause new channel key generation
2794 which it of course should've done. The channel keys must be
2795 always re-generated when client leaves (or signoffs) the channel.
2796 The silc_server_remove_from_channels funtion now handles
2797 the channel key re-generation.
2799 * Added `sender' argument to the silc_server_send_notify_on_channels
2800 to not to send the client provided as argument. Affected file
2801 silcd/packet_send.[ch].
2803 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Implemented OPER and SILCOPER commands into the server and
2808 * Added silc_auth_verify and silc_auth_verify_data to verify
2809 the authentication directly from the authentication payload.
2810 It supports verifying both passphrase and public key based
2811 authentication. Affected file lib/silccore/silcauth.[ch].
2813 * Added `hash' field to the SilcIDListData structure. It is the
2814 hash negotiated in the SKE protocol. Affected file is
2817 * Slight redesigning of the SilcAuthPayload handling routines.
2818 Do not send SilcPKCS but SilcPublicKey as argument.
2820 * Implemented the public key authentication support to the
2821 serverconfig. The public key is loaded from the provided path
2822 and saved as authentication data to void * pointer. Thus,
2823 changed the unsigned char *auth_data to void *auth_data;
2825 * Fixed SHUTDOWN command to send the reply before the server
2826 is shutdown. :) Affected file silcd/command.c.
2828 * Fixed fatal bug in CONNECT command. The hostname was invalid
2829 memory and server crashed. Affected file silcd/command.c.
2831 * Fixed fatal bug in CLOSE command. The server_entry became
2832 invalid but was referenced later in the command. Affected file
2835 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Fixed fatal bug in failure packet handling. Server ignored
2838 the failure and thus crashed when it came.
2842 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2845 that the command may be executed only once in (about) 2 seconds.
2846 The old SILC_CF_LAG flag is same but allows command bursts up
2847 to five before limiting.
2849 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2850 server code. Various commands now includes the CF_LAG_STRICT
2851 flag to disallow any kind of miss-use of the command.
2853 * Fixed the silc_buffer_unformat to not to allocate any data
2854 if the length of the data is zero. It used to allocate the
2855 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2857 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Changed the format of AdminConnection configuration section
2860 in the server. Added username of the admin to the format.
2861 Affected files silcd/serverconfig.[ch].
2863 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2864 to return admin configuration data by host, username and/or
2867 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Implemented WHOWAS command to the server. Added the functions:
2871 silc_server_command_whowas_parse,
2872 silc_server_command_whowas_send_reply,
2873 silc_server_command_whowas_from_client and
2874 silc_server_command_whowas_from_server
2876 * Added <Client ID> argument to the WHOWAS command reply. Updated
2877 the protocol specs accordingly.
2879 * Implemented WHOWAS command and command_reply to the client
2882 Implemented the WHOWAS printing on the user interface.
2884 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Added new argument to the WHOWAS command reply, the real name.
2887 It is an optional argument. Updated the protocol specs.
2889 * Added SilcIDCacheDestructor callback that is registered when
2890 the SilcIDCache is allocated. The callback is called when
2891 an cache entry in the ID Cache expires, or is purged from the
2892 cache. Added into lib/silccore/idcache.[ch].
2894 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2895 to destruct the client entries when the cache entry expires.
2896 Other ID Cache's in server and in the client library ignores
2899 * If the ID Cache entry's `expire' field is zero then the entry
2900 never expires. Added boolean `expire' argument to the
2901 silc_idcache_add function in the lib/silccore/idcache.[ch].
2902 If it is TRUE the default expiry value is used.
2904 * Added silc_server_free_client_data_timeout that is registered
2905 when client disconnects. By default for 5 minutes we preserve
2906 the client entry for history - for WHOWAS command.
2908 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Added support to the server to enforce that commands are not
2911 executed more than once in 2 seconds. If server receives
2912 commands from client more frequently, timeout is registered
2913 to process the commands. Affected file silcd/command.c.
2914 Added new function silc_server_command_process_timeout.
2916 * Changed NICK_NOTIFY handling in client library to check that
2917 if the client's nickname was changed, so there is no need to
2918 resolve anything from the server.
2920 * Removed error printing from the WHOIS and IDENTIFY commands.
2921 If error occurs then it is ignored silently in the client library.
2922 The application, however, may map the received error to
2923 human readable error string. The application currently maps
2924 the NO_SUCH_NICKNAME error to string.
2926 * Made the command status message public to the application. Moved
2927 them from lib/silcclient/command_reply.c to
2928 lib/silcclient/command_reply.h. The application can map the
2929 received command status to the string with the
2930 silc_client_command_status_message function.
2932 * Added check to the server to check that client's ID is same
2933 as the Source ID in the packet the client sent. They must
2936 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Added dist-bzip hook to the Makefile.am to make bzip2
2939 compressed distributions.
2941 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * Server now enforces the maximum length for the nickname and
2944 the channel as protocol specification dictates. 128 bytes for
2945 nickname and 256 bytes for channel name.
2947 * Moved the WHOIS printing to the application. The client libary
2948 does not print out the WHOIS information anymore, the application
2949 must do it. Renamed silc_client_command_reply_whois_print to
2950 the silc_client_command_reply_whois_save.
2952 The client's idle time is also sent to the application now, and
2953 the idle is shown on screen.
2955 * Added silc_client_command_reply_identify_save to save the
2956 received IDENTIFY entries.
2958 * Do not check for channel private keys in message sending and
2959 reception if the channel does not have the PRIVKEY mode set.
2960 Affected file lib/silclient/client_channel.c.
2962 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2965 just surfaced after chaning the JOIN procedure.
2967 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Added silc_client_get_clients_by_list to get client entries
2970 from Client ID list, that is returned for example by JOIN
2971 and USERS command replies. The application should use this
2972 function for example when JOIN command reply is received to
2973 resolve the clients already on the channel (library does not
2974 do that anymore as USERS command reply is not used in the JOIN
2975 procedure anymore). Affected files lib/silcclient/silcapi.h and
2976 lib/silcclient/idlist.c.
2978 * JOIN command reply and USERS command reply returns now SilcBuffer
2979 pointers instead of unsigned char pointers when returning
2980 the client list and mode list.
2982 * Added <Client ID> argument to the JOIN command reply, mainly
2983 for the server to identify for which client the command was
2984 originally sent. Updated protocol specs accordingly.
2986 * Added SilcDlist private_key pointer to the SilcChannelEntry
2987 in the client to support the channel private keys. Affected
2988 file is lib/silcclient/idlist.h.
2990 * Added SilcChannelPrivateKey argument to the function
2991 silc_client_send_channel_message so that application can choose
2992 to use specific private ke if it wants to. If it is not provided,
2993 the normal channel key is used, unless private keys are set.
2994 In this case the first (key that was added first) is used
2995 as the encryption key.
2997 * Implemented the support for channel private key handling.
2998 Implemented the following functions:
3000 silc_client_add_channel_private_key,
3001 silc_client_del_channel_private_keys,
3002 silc_client_del_channel_private_key,
3003 silc_client_list_channel_private_keys and
3004 silc_client_free_channel_private_keys
3006 Affected file lib/silcclient/client_channel.c.
3008 * Added the support for the private keys in the channel message
3009 sending and encryption and in the message reception and
3010 decryption. Affected funtions are
3011 silc_client_send_channel_message and silc_client_channel_message.
3013 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Added SKE's key verify callback to the client library's
3016 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3018 * Removed the statement that server (or router) must send USERS
3019 command reply when joining to the channel so that the client
3020 knows who are on the channel. Instead, the client list and
3021 client's mode list is now sent in the JOIN command reply to the
3022 client who joined channel. This is better solution.
3024 * Added function silc_server_get_users_on_channel and function
3025 silc_server_save_users_on_channel to the silcd/server.[ch].
3027 * Removed function silc_server_command_send_users from the
3030 * Do not show topic on the client library anymore. The topic is
3031 sent in the command reply notify to the application and the
3032 application must show the topic now.
3034 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Added client searching by nickname hash into the IDENTIFY and
3037 WHOIS commands in the server as they were clearly missing from
3038 them. Affected file is silcd/command.c.
3040 * Fixed a bug in private message receiving in the client library.
3041 The remote ID was freed and it wasn't supposed, now it is
3044 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Minor fix to the channel payload; allocate the data area, as it
3047 needs to be of specific length.
3049 * If the key agreement port is zero then the operating
3050 system will define the bound port. Affected files are
3051 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3053 * Added new function silc_channel_payload_decrypt into the file
3054 lib/silccore/silcchannel.[ch].
3056 * Moved the channel message etc, check from silc_packet_decrypt
3057 to applications. The library calls now a generic
3058 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3059 when the packet is either normal or special. This was done to
3060 allow more wide range of checking that was not allowed when
3061 the code was in library. Now applications can do virtually any
3062 checks to the packet and return to the library the decision how
3063 the packet should be processed. Affected files are
3064 lib/silccore/silcpacket.[ch].
3066 Added silc_server_packet_decrypt_check to the server and
3067 silc_client_packet_decrypt_check to the client library.
3069 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3070 to send with specified source and destination information.
3072 * Channel message delivery between routers was broken after the
3073 channel key distribution was fixed earlier. The channel key
3074 was used be to distributed to other routers as well which is not
3075 allowed by the protocol. Now this is fixed and channel keys
3076 really are cell specific and the channel message delivery between
3077 routers comply with the protocol specification.
3079 * Fixed various commands in server to check also the global list
3080 for the channel entry and not just the local list. The affected
3081 file silcd/command.c.
3083 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Added assert()s to buffer formatting and unformatting routines
3086 to assert (if --enable-debug) when error occurs. Affected
3087 file: lib/silcutil/silcbuffmt.c.
3089 * Changed to auto-reconnect to check whether the remote host is
3090 router and register the re-connect timeout if it is. It used
3091 to check that whether we are normal server, but router must do
3092 auto-reconnect with another router as well. Affected file
3095 * Removed the [<key len>] option from CMODE command as the cipher
3096 name decides the key length, nowadays. See the defined ciphers
3097 from the protocol specification.
3099 * Added [<hmac>] option to the CMODE command to define the HMAC
3100 for the channel. Added SILC_CMODE_HMAC channel mode.
3102 * Added [<hmac>] option for the JOIN command so that user can
3103 select which HMAC is used to compute the MACs of the channel
3106 * Added Hmac field to the Channel Message Payload. The integrity
3107 of plaintext channel messages are now protected by computing
3108 MAC of the message and attaching the MAC to the payload. The
3109 MAC is encrypted. Now, it is clear that this causes some
3110 overhead to the size of the packet but rationale for this is that
3111 now the receiver can verify whether the channel message decrypted
3112 correctly and also when private keys are set for the channel the
3113 receiver can decrypt the packet with several keys and check from
3114 the MAC which key decrypted the message correctly.
3116 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3117 lib/silccrypt/silccipher.[ch].
3119 * Added silc_hash_len to return the digest length into the
3120 lib/silcrypt/silchash.[ch].
3122 * Rewrote parts of Silc Channel Payload interface in the
3123 lib/silccore/silcchannel.[ch]. The encode function now also
3124 encrypts the packet and parse function decrypts it.
3126 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Fixed a minor formatting bug in the SKE's key material processing.
3129 It actually might have processed the keys wrong way resulting
3132 * Redefined the mandatory HMAC algorithms and added new algorithms.
3133 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3134 and hmac-md5 truncated to 96 bits. The mandatory is now
3135 hmac-sha1-96. Rest are optional (including the one that used
3136 to be mandatory). Rationale for this is that the truncated HMAC
3137 length is sufficient from security point of view and can actually
3138 make the attack against the HMAC harder. Also, the truncated
3139 HMAC causes less overhead to the packets. See the RFC2104 for
3142 * Added new [hmac] configuration section. The SKE used to use
3143 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3144 is of course wrong. The official names that must be proposed in
3145 the SKE are the ones defined in the protocol specification
3146 (hmac-sha1-96 for example). The user can configure any hmac
3147 using any hash function configured in the [hash] section. At
3148 least, the mandatory must be configured.
3150 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3152 * Added HMAC list to the SKE proposal list. It has now both
3153 hash algorithm list and HMAC list. This makes the protocol
3154 incompatible with previous versions. The SKE now seems to work
3155 the way it is supposed to work, for the first time actually.
3157 * Defined plain Hash algorithms to the protocol specification.
3160 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Implemented support for key agreement packets into the server.
3163 Added functions silc_server_key_agreement and
3164 silc_server_send_key_agreement. Other than these functions,
3165 server has nothing to do with this packet.
3167 * Added support for private message key packets into the server.
3168 Added functions silc_server_private_message_key and
3169 silc_server_send_private_message_key.
3173 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3174 called in the protocol's final callback instead in the END
3175 protocol state. This makes a little more sense and in the same
3176 time in client we can use the same protocol routines for normal
3177 key exchange and to key agreement packet handling as well.
3179 * Added to both client's and server's KE protocol context the
3180 SilcSKEKeyMaterial pointer to save the key material. We will
3181 bring the key material to the protocol's final callback by doing
3182 this. The final callback must free the key material.
3184 * Added SKE's packet_send callback into client's KE protocol
3185 context so that the caller can choose what packet sending function
3186 is used. This way we can use different packet sending when
3187 doing normal SKE when doing key agreement packet handling (in
3188 the key agreement packet handling we do not want to encrypt
3191 * Implemented the responder side of the key agreement routines
3192 in the client. The client can now bind to specified port and
3193 accept incoming key negotiation. The key material is passed
3194 to the application after the protocol is over.
3196 * Implemented the processing of incoming Key Agreement packet
3197 in the client. Added function silc_client_key_agreement to
3200 * Implemented the intiator side of the key agreement routines
3201 in the client. The client can now initiate key agreement with
3202 another remote client. The key material is passed to the
3203 application after the protocol is over.
3205 * Created client_keyagr.c to include all the key agreement
3208 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3209 SILC_TASK_CALLBACK except that it is not static.
3211 * Created client_notify.c and moved the Notify packet handling
3212 from the client.[ch] into that file.
3214 * Created client_prvmsg.c and moved all private message and
3215 private message key routines from the client.[ch] into that file.
3217 * Create client_channel.c and moved all channel message and
3218 channel private key routines from the client.[ch] into that file.
3220 * Changed silc_client_get_client_by_id_resolve to resolve with
3221 WHOIS command instead of IDENTIFY command, in the file
3222 lib/silclient/idlist.c.
3224 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Implemented the SKE's responder side to the Client library.
3228 * When FAILURE is received to the protocol do not trust it
3229 blindly. Register a timeout to wait whether the remote closes
3230 the connection as it should do it, only after that process the
3231 actual failure. This was changed to both client and server.
3233 * Added client_internal.h to include some of the structures
3234 there instead of client.h in lib/silcclient/.
3236 * Added function silc_task_unregister_by_callback to unregister
3237 timeouts by the callback function.
3239 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Some "Incomplete WHOIS info" errors has been appearing on the
3242 log files. Took away the entry->userinfo check from WHOIS
3243 reply sending. The entry->userinfo is now " " if client did not
3244 provide one. I thought this was fixed earlier but something
3245 is wrong still. Let's see if the error still appears.
3247 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Fixed a minor bug in the login when the channel key is
3250 re-generated in the server. It used to generate the key in
3251 wrong order and thus caused problems in the channel traffic.
3253 * Fixed a minor bug in channel key distsribution after
3254 KICK command. The key was not sent to the router even though
3257 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Added silc_ske_process_key_material_data as generic routine
3260 to process any key material as the SILC protocol dictates. The
3261 function is used by the actual SKE library but can be used by
3262 applications as well. This relates to the private message keys
3263 and the channel private keys since they must be processed the
3264 same way the normal SILC session keys. The protocol dictates
3265 this. Affected files: lib/silcske/silcske.[ch].
3267 Added also silc_ske_free_key_material to free the
3268 SilcSKEKeyMaterial structure.
3270 * Defined silc_cipher_set_key function to set the key for
3271 cipher without using the object's method function. The affected
3272 files: lib/silccrypt/silccipher.[ch].
3274 * Implemented silc silc_client_add_private_message_key,
3275 silc_client_add_private_message_key_ske,
3276 silc_client_del_private_message_key,
3277 silc_client_list_private_message_keys and
3278 silc_client_free_private_message_keys functions in the
3281 Added functions silc_client_send_private_message_key to send
3282 the Private Message Key payload and silc_client_private_message_key
3283 to handle incoming Private Message Key payload.
3285 * Added Cipher field to the Private Message Key payload to set
3286 the cipher to be used. If ignored, the default cipher defined
3287 in the SILC protocol (aes-256-cbc) is used.
3289 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Removed lib/silcclient/ops.h file.
3293 Redefined parts of the SILC Client Library API. Created new
3294 file silcapi.h that deprecates the ops.h file and defines the
3295 published Client Library API. Defined also private message key
3296 API and channel private key API into the file.
3298 This is the file that the application must include from the
3299 SILC Client Library. Other files need not be included by
3300 the application anymore.
3302 * Added new key_agreement client operation callback and also
3303 defined the Key Agreement library API for the application.
3305 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3308 is used by clients to request key negotiation between another
3309 client in the SILC network. If the negotiation is started it
3310 is performed using the SKE protocol. The result of the
3311 negotiation, the secret key material, can be used for example
3312 as private message key.
3314 Implemented the Key Agreement payload into the files
3315 lib/silccore/silauth.[ch].
3317 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Redefined ciphers for the SILC protocol. Added some new ciphers
3320 and defined the key lengths for the algorithms. Changed the
3321 code accordingly. The default key length is now 256 bits.
3323 * Fixed SKE key distribution function silc_ske_process_key_material
3324 when the key length is more than 128 bits. The default key
3325 length in SILC is now 256 bits.
3327 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3328 to indicate unsupported algorithm.
3330 * Renamed rijndael.c to aes.c and all functions as well.
3332 * Fixed a long standing channel key setting bug in client library.
3333 Weird that it has never surfaced before.
3335 * Fixed bug in channel deletion. If the entire channel is removed
3336 then it must also delete the references of the channel entry
3337 from the client's channel list as the client's channel entry and
3338 the channel's client entry share same memory.
3340 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Implemented CONNECT and SHUTDOWN commands in the client.
3344 * Implemented CLOSE command to the client.
3346 * Added the function silc_idlist_find_server_by_name into the
3347 files silcd/idlist.[ch].
3349 Added the function silc_idlist_find_server_by_conn into the
3350 files silcd/idlist.[ch].
3352 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * DIE command was renamed to SHUTDOWN. Updated the both code
3357 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3358 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3360 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3363 * Added function silc_server_create_connection function to create
3364 connection to remote router. My server implementation actually
3365 does not allow router to connect to normal server (it expects
3366 that normal server always initiates the connection to the router)
3367 so the CONNECT command is only good for connecting to another
3370 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3373 or some other client was kicked from the channel.
3375 Implemented the handling of the notify type to both client
3378 Implemented silc_server_send_notify_kicked to send the KICKED
3379 notify. It is used to send it to the server's primary router.
3381 * Implemented the KICK command into server and client.
3383 * Added `query' argument to the silc_idlist_get_client function
3384 to indicate whether to query the client from server or not if
3387 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3388 to indicate that the client is not channel founder.
3392 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * Removed the rng context from SilcPacketContext structure and
3395 changed that the packet routine uses the Global RNG API.
3397 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Added support for quit message that client can "leave" on the
3400 channel when it quits the SILC. It is ditributed inside the
3401 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3403 Added silc_server_free_client_data that will take the
3404 signoff message as argument.
3406 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3408 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Updated parts of the protocol specification to keep it up
3413 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3416 payloads in one packet.
3418 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3419 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3420 use now the new List flag.
3422 * Also deprecated the following packet types: REPLACE_ID,
3423 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3425 * Added list support for Notify packet in server.
3427 * Added silc_server_send_notify_channel_change to send the
3428 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3429 the silc_server_send_replace_id.
3431 * Added silc_server_send_notify_nick_change to send the
3432 NICK_CHANGE notify type. Deprecates the function
3433 silc_server_send_replace_id.
3435 * Added silc_server_send_notify_join to send the JOIN notify type.
3436 Deprecates the function silc_server_send_new_channel_user.
3438 * Added silc_server_send_notify_leave to send LEAVE notify type.
3439 Deprecates the function silc_server_send_remove_channel_user.
3441 * Added silc_server_send_notify_cmode and
3442 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3443 types. Deprecates the silc_server_send_set_mode function.
3445 * Added SERVER_SIGNOFF notify type to indicate that server has
3446 quit. This means that all clients on the channel from that
3447 server will drop. This can be also used when netsplit happens.
3449 Deprecated REMOVE_ID packet type since it is not needed anymore
3452 Added silc_server_send_notify_server_signoff to send the
3453 SERVER_SIGNOFF notify type. Deprecates the function
3454 silc_server_send_remove_id.
3456 Added also silc_server_send_notify_signoff to send the
3457 SIGNOFF notify type.
3459 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3460 SILC protocol from this day on. Changed the protocol
3461 specification as well.
3463 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3464 notify type. It is used between routers to notify about
3465 topic changes on a channel.
3467 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3470 * Partly updated the protocol specification to comply with the
3471 changes now made. It is still though a bit outdated.
3473 * The JOIN notify type now takes one extra argument <Channel ID>.
3474 The packet used to be destined to the channel but now the
3475 JOIN type may be sent as list thus it is impossible to
3476 destine it to any specific channel. By adding this argument
3477 it is again possible.
3479 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Added CREDITS file. The CHANGES and CREDITS file will appear
3482 in the distribution as well.
3484 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3487 types in the server's silcd/packet_receive.c.
3489 * Implemented CMODE and CUMODE to work in router environment.
3491 * Fixed minor encoding and decoding buglet from the
3492 lib/silccore/silcmode.c.
3494 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3497 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3499 * Changed all SilcConfigServer* and silc_config_server* to
3500 SilcServerConfig* and silc_server_config*, respectively.
3503 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Associated the ID (client or server ID) to the Authentication
3506 Payload to avoid any possibility of forging. Updated the
3507 protocol specification and the code accordingly.
3509 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * The RSA key length is now save to the RsaKey context in the
3512 key generation process in lib/silccrypt/rsa.c. The key length
3513 is now used to figure out the maximum size of the block allowed
3514 to be encrypted/signed.
3516 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3517 is equivalent to the silc_mp_mp2bin but does not allocate any
3520 * Changed silc_mp_mp2bin API to take length argument. If it is
3521 non-zero then the buffer is allocated that large. If zero, then
3522 the size is approximated using silc_mp_sizeinbase, which however
3525 * Created Global RNG API which is global RNG that application can
3526 initialize. After initializing, any routine anywhere in the
3527 code (including library) can use RNG without allocating a new
3528 RNG object. This was done to allow this sort of use of the
3529 RNG in code that has no chance to allocate RNG object. All
3530 applications currently allocate this and many routines in the
3531 library use this. Affected file lib/silccrypt/silcrng.[ch].
3533 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3534 it to use the Global RNG API.
3536 * Defined Authentication Payload into protocol specification that
3537 is used during SILC session to authenticate entities. It is
3538 used for example by client to authenticate itself to the server
3539 to obtain server operator privileges.
3541 Implemented this payload into the lib/silccore/silcauth.[ch].
3542 Implemented also routines for public key based authentication
3543 as the new protocol specification dictates.
3545 Moved definitions of different authentication methods from
3546 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3548 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3549 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3550 silc_pkcs_verify_with_hash functions into the file
3551 lib/silccrypt/silcpkcs.[ch].
3553 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * The client entry's userinfo pointer must be always valid.
3556 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3557 will fail since it requires the userinfo. Now, the userinfo
3558 is allocated as "" if actual userinfo does not exist. Actually,
3559 it must exist and it is totally Ok to drop client connections
3560 that does not announce the userinfo. However, we will make
3561 this workaround for now.
3563 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3564 to return the remote port by socket.
3566 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3569 SILC_SERVER_PENDING_EXEC and added an new macro
3570 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3571 data or when error occurs while processing the pending command.
3573 Added new argument `destructor' into silc_server_command_pending
3574 and to the SilcServerCommandPending object. This destructor is
3575 now called after calling the pending callback or if error occurs
3576 immediately. If error occurs the actual pending callback won't
3577 be called at all - only the destructor. The destructor may be
3578 NULL if destructor is not needed.
3580 All this applies for client library code as well. Similar
3581 changes were made there as well for the pending commands.
3583 In the client, the application must now allocate the
3584 SilcClientCommandContext with the silc_client_command_alloc
3587 * Added reference counter to the SilcServerCommandContext. Added
3588 function silc_server_command_alloc and silc_server_command_dup
3591 Same type of functions added to the client library for the same
3594 * Removed the cmd_ident from IDListData away since it is now
3595 global for all connections. It is the command identifier used
3596 in command sending and with pending commands. The affected file
3599 * Added reference counter to the SilcSocketConnection objecet to
3600 indicate the usage count of the object. The object won't be
3601 freed untill the reference counter hits zero. Currently only
3602 server uses this, and client ignores it. The client must be
3603 set to use this too later. The affected files are
3604 lib/silccore/silcsockconn.[ch]. Added also the function
3605 silc_socket_dup to increase the reference counter.
3607 This was mainly added because it is possible that the socket
3608 is removed underneath of pending command or other async
3609 operation. Now it won't be free'd and proper DISCONNECTING
3610 flags, etc. can be set to avoid sending data to connection that
3611 is not valid anymore.
3613 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3614 the connection. After that it sets SILC_SET_DISCONNECTED.
3615 It is, however, possible that the socket data is not still freed.
3616 The silc_server_packet_process now checks that data is not
3617 read or written to connection that is DISCONNECTED. The socket
3618 get's freed when the reference counter hits zero.
3620 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Changed the client operation API: channel_message operation's
3623 `sender' is now the client entry of the sender, not the nickname
3624 and the `channel' is the channel entry, not the channel name.
3626 In the private_message operation the `sender' is now also the
3627 client entry of the sender not the nickname.
3629 Affected file is lib/silcclient/ops.h and all applications
3630 using the client operations.
3632 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Moved the calling of ops->connect() from connect_to_server_final
3635 into receive_new_id functin since that is the point when the
3636 client is actually allowed to send traffic to network. The
3637 affected file is lib/silcclient/client.c.
3639 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3642 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3643 (if needs broadcasting) instead of broadcasting the packets one
3644 by one which would make a burst in the network traffic.
3646 * Added `broadcast' argument to the functions in silcd/server.[ch]
3647 silc_server_create_new_channel[_with_id] to indicate whether
3648 to send New Channel packet to primary router.
3650 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added new function into the silcd/server.[ch] files:
3653 silc_server_create_new_channel_with_id to create new channel with
3654 already existing Channel ID.
3656 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3657 lib/silccore/silcpacket.h. This packet is used t send list of
3658 Set Mode payloads inside one packet. Server uses this to set
3659 the modes for the channels and clients on those channels, that it
3660 announced to the router when it connected to it. The protocol
3661 specification has been updated accordingly.
3663 * The silc_server_new_channel did not handle the packet coming
3664 from normal server as it normally does not send that. However,
3665 when it announces its channels it does send it. Implemented
3666 the support for that.
3668 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3669 into the file lib/silccore/id.h.
3671 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Fixed memory leaks in the functions silc_idlist_del_client,
3674 silc_idlist_del_channel and silc_idlist_del_server in the file
3675 silcd/idlist.c. All of those leaked like a sieve.
3677 * Fixed some small memory leaks in the client's function
3678 silc_client_notify_by_server.
3680 * Added functions into silcd/server.c: silc_server_announce_clients,
3681 silc_server_announce_channels and silc_server_announce_server.
3682 These functions are used by normal and router server to announce
3683 to its primary router about clients, channels and servers (when
3684 router) that we own. This is done after we've connected to the
3687 These functions effectively implements the following packet types:
3688 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3689 and SILC_PACKET_NEW_ID_LIST.
3691 * Added new functions into the silcd/packet_receive.[ch]:
3692 silc_server_new_id_list, silc_server_new_channel_list and
3693 silc_server_new_channel_user_list to handle the incoming
3694 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3696 * Added support of changing Channel ID in the function
3697 silc_server_replace_id. If the server that announces a channel
3698 to the router already exists in the router (with same name but
3699 with different Channel ID), router is responsible to send
3700 Replace ID packet to the server and force the server to change
3701 the Channel ID to the one router has.
3703 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3704 client that the Channel ID has been changed by the router. The
3705 normal server sends this to the client. Client must start using
3706 the new Channel ID as the channel's ID.
3708 Implemented handling of this new type into lib/silcclient/client.c
3709 into the function silc_client_notify_by_server.
3711 * Added new function silc_idlist_replace_channel_id into the files
3712 silcd/idlist.[ch] to replace the Channel ID.
3714 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Call silc_server_command_identify_check always when processing
3717 the IDENTIFY command in silcd/command.c
3719 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3722 send keepalive packets. The packet can be sent by clients,
3723 servers and routers.
3725 Added function silc_socket_set_heartbeat into the file
3726 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3727 If not set, the heartbeat is not performed. The actual
3728 heartbeat is implemented in the low level socket connection
3729 library. However, application is responsible of actually
3732 Added silc_server_send_heartbeat to send the actual heartbeat
3733 packet into silcd/packet_send.[ch]. Server now performs
3734 keepalive with all connections.
3736 * Added silc_task_get_first function into lib/silcutil/silctask.c
3737 to return the timeout task with shortest timeout. There was a bug
3738 in task unregistration that caused problems. TODO has been
3739 updated to include that task system must be rewritten.
3741 * The client library will now resolve the client information when
3742 receiving JOIN notify from server for client that we know but
3743 have incomplete information.
3745 * Rewrote parts of silc_server_remove_from_channels and
3746 silc_server_remove_from_one_channel as they did not remove the
3747 channel in some circumstances even though they should've.
3749 * Encryption problem encountered in server:
3751 The LEAVE command used to send the Channel Key packet to the
3752 router immediately after generating it. However, the code
3753 had earlier sent Remove Channel user packet but not immediately,
3754 ie. it was put to queue. The order of packets in the router
3755 was that Channel Key packet was first and Remove Channel User
3756 packet was second, even though they were encrypted in the
3757 reverse order. For this reason, MAC check failed. Now, this
3758 is fixed by not sending the Channel Key packet immediately but
3759 putting it to queue. However, this is more fundamental problem:
3760 packets that are in queue should actually not be encrypted
3761 because packets that are sent immediately gets encrypted
3762 actually with wrong IV (and thus MAC check fails). So, packets
3763 that are in queue should be encrypted when they are sent to
3764 the wire and not when they put to the queue.
3766 However, the problem is that the current system has not been
3767 designed to work that way. Instead, the packet is encrypted
3768 as soon as possible and left to the queue. The queue is then
3769 just purged into wire. There won't be any fixes for this
3770 any time soon. So, the current semantic for packet sending
3773 o If you send packet to remote host and do not force the send
3774 (the packet will be in queue) then all subsequent packets to the
3775 same remote host must also be put to the queue. Only after the
3776 queue has been purged is it safe again to force the packet
3779 o If you send all packets immediately then it safe to send
3780 any of subsequent packets through the queue, however, after
3781 the first packet is put to queue then any subsequent packets
3782 must also be put to the queue.
3784 Follow these rules and everything works fine.
3786 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Added new function silc_server_remove_clients_by_server to
3789 remove all client entries from ID list when the server connection
3790 is lost. In this case it is also important to invalidate all
3791 client entires as they hold the invalid server entry. This
3792 fixes fatal bug when server has lost connection and will reconnect
3795 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Made some sanity checks to silc_server_daemonise like to check
3798 whether the requested user and group actually exists.
3800 * Added sanity check to SKE's silc_ske_responder_finish to check
3801 that the public and private key actually is valid.
3803 * Invalidate the client's nickname when receiving Replace ID
3804 packet and the Client ID is being replaced. This means that the
3805 server will query the nickname if someone needs it (client)
3808 * Sort the ID Cache in client library when the ID Cache data
3809 has changed (needs sorting).
3811 * Do not allow for SILC client to create several connections to
3812 several servers. The client does not support windows right now
3813 and generating multiple connections causes weird behaviour.
3815 Irssi-silc client does support windows and can handle several
3816 connections without problems, see: www.irssi.org and SILC plugin.
3818 * Fixed some places where client was added to the IDList. The
3819 rule of thumb is following (in order to get everything right):
3820 If the client is directly connected local client then the
3821 `connection' argument must be set and `router' argument must be
3822 NULL to silc_idlist_add_client function. If the client is not
3823 directly connected client then the `router' argument must
3824 bet set and the `connection' argument must be NULL to the
3825 silc_idlist_add_client function.
3827 * The funtion silc_server_packet_send_local_channel actually did
3828 not check whether the client was locally connected or not. It
3829 does that now. Fixed a bug related to LEAVE command.
3831 * Fixed Remove Channel User payload parsing bug in server's
3832 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3834 * The server's silc_server_save_channel_key now checks also the
3835 global ID list for the channel as it might not be in the local
3836 list. Fixed a bug related to LEAVE command.
3838 * Is this the end of the [<unknown>] buglet that has been lurking
3839 around for a long time? A little for loop fix in server's
3840 silc_server_command_whois_parse that is used by both IDENTIFY
3841 and WHOIS command. At least, this was a clear bug and a cause
3842 of one type of [<unknown>] buglet.
3844 * WHOIS and IDENTIFY commands call the function
3845 silc_server_command_[whois/identify]_check function even if
3846 we are not router server.
3848 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Added --with-gmp configuration option. If set the GMP
3851 is always compiled in the SILC source tree. If not set then
3852 it is checked whether the system has the GMP3 installed. If
3853 it has then the GMP won't be compiled (the system's headers
3854 and library is used), if it doesn't have it then the GMP is
3855 compiled in the SILC source tree.
3857 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Changed RSA private exponent generation to what PKCS #1
3860 suggests. We try to find the smallest possible d by doing
3861 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3862 not security fix but optimization.
3864 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Added new config entry [Identity] to fork the server and run
3867 it as specific user and group. A patch from Bostik.
3869 * Imported Dotconf configuration library into lib/dotconf.
3870 This will be used to create the SILC configuration files later.
3871 It will appear in the distsribution after this commit.
3873 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * A big code auditing weekend happening. Auditing code for
3876 obvious mistakes, bugs and errors. Also, removing any code
3879 Removed files for being obsolete:
3881 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3882 inline in the file lib/silcutil/silcbuffer.h)
3884 o lib/silcutil/silcbufutil.c (the header has inline versions)
3886 Changed code to fix possible error conditions:
3888 o The buffer formatting routines now check that the destination
3889 buffer really has enough space to add the data. This applies for
3890 both buffer formatting and unformatting
3891 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3892 unformatting was changed to accomodate following rules:
3893 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3894 sent to the function while XXX_*STRING will not allocate or copy
3895 the data into the buffer. Instead it sets the pointer from the
3896 buffer into the pointer sent as argument (XXX_*STRING used to
3897 require that the pointer must be allocated already). This change
3898 makes this whole thing a bit more consistent and more optimized
3899 (note that the data returned in the unformatting with XXX_*STRING
3900 must not be freed now). The routines return now -1 on error.
3902 o Tried to find all code that use buffer_format and buffer_unformat
3903 and added return value checking to prevent formatting and
3904 especially unformatting errors and possible subsequent fatal
3907 o Changed ske->x and ske->KEY to mallocated pointers in
3908 lib/silcske/silcske.h. Fixed possible data and memory leak.
3910 o Added return value checking to all *_parse* functions. Fixed
3911 many memory leaks as well.
3913 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3914 so that buffer overflows would not happen. All code now also
3915 checks the return value as it can fail.
3917 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Added reconnection support to server if the normal server looses
3920 its connection to the router (for example if router is rebooted).
3921 The server performs normal reconnection strategy implemented
3922 to the server. Affected file silcd/server.c.
3924 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Added new packet type SILC_PACKET_SET_MODE that is used to
3927 distribute the information about changed modes (for clients,
3928 channels and clients channel modes) to all routers in the
3929 network. Updated the protocol specification accordingly.
3931 Added functions into silcd/packet_send.c and
3932 silcd/packet_receive.c: silc_server_send_set_mode,
3933 silc_server_set_mode.
3935 Added new files silcmode.[ch] into lib/silccore that implements
3936 the encoding and decoding of Set Mode Payload. Added new type
3937 SilcSetModePayload. Moved the definitions of different modes
3938 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3940 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Oops, a little mistake in server's connection authentication
3943 protocol. The protocol is not ended with FAILURE but with
3944 SUCCESS if the authentication is Ok. :) Affected file is
3947 * Implemented NICK_CHANGE notify handling in server in the file
3948 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3949 the local clients on the channel. After the changing nickname
3950 in router environment snhould work and the [<unknown>] nickname
3951 should appear no more.
3953 The silc_server_replace_id function that receives the Replace ID
3954 payload now sends the NICK_CHANGE notify type also in the file
3955 silcd/packet_receive.c
3957 * Changed WHOIS and IDENTIFY command to support the maximum amount
3958 of arguments defined in protocol specs (3328 arguments). This
3959 fixed a bug that caused problems when there were more than three
3962 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Added extra parameter, command identifier, to the
3965 silc_client_send_command so that explicit command identifier
3968 Changed that ID list routines uses specific command identifier
3969 when sending WHOIS/IDENTIFY requests to the server so that they
3970 can be identified when the reply comes back.
3972 Affected files lib/silcclient/command.[ch],
3973 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3975 * Added `sender' argument to silc_server_packet_send_to_channel
3976 to indicaet the sender who originally sent the packet to us
3977 that we are now re-sending. Ignored if NULL. Affected file
3978 silcd/packet_send.[ch].
3980 * Added some server statistics support in silcd/server_internal.h
3981 SilcServerStatistics structure and around the server code. Also
3982 send some nice statistics information when client is connecting
3985 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Fixed channel ID decoding in server's JOIN command reply in
3988 silcd/command_reply.c
3990 * Fixed braodcasting of replace ID payload to not to send it if
3991 we are standalone server in silcd/packet_receive.c.
3993 * Fixed all channel message sending routines to not to send
3994 packets to clients that has router set, since they are routed
3995 separately in the same function earlier. Affects file
3996 silcd/packet_send.c and all channel packet sending functions.
3998 * In USERS reply, res_argv[i] are not allocated, the table
3999 is allocated. Thus changed that free the table, not its
4002 * In server's whois_check and identify_check if the client is
4003 locally connected do not send any WHOIS commands - they are not
4006 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Fixed some minor bugs in client when sending WHOIS command. The
4009 arguments was in wrong order.
4011 * Removed statis function add_to_channel from server in
4012 silcd/command.c that was previously used with the joining but
4015 * Tested USERS command in router environment successfully with two
4016 routers, two servers and two clients.
4018 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Reorganized the USERS command and command reply in client library
4021 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4022 When the command is given by user we register a pending command
4023 callback that will reprocess the command after the reply has been
4024 received from the server. When reprocessing the packet we then
4025 display the information. Thus, the USERS information is displayed
4026 now in the command callback instead of in the command reply
4027 callback. The processing of the command is same as previously
4028 when server has sent the command reply in the JOINing process.
4030 * Added to USERS command in silcd/command_reply.c to join the client,
4031 we didn't use to know about, to the channel after we've created
4032 a client entry for it. Also, for clienet we did know already still
4033 check whether it is on the channel or not and add it if not.
4035 * Removed silc_server_command_join_notify as the function and its
4038 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Changed the client's pending command handling to the same as the
4041 server's pending command handling. It is also now possible to
4042 execute command reply functions from other command reply
4043 function as the function callbacks for commands and command
4044 replies are one and same. The pending commands are not static
4045 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4046 in client connection context. Thus, pending commands are server
4047 connection specific as it is convenient.
4049 Changed the function silc_client_command_pending and
4050 silc_client_command_pending_del and added new function
4051 silc_client_command_pending_check. Removed the
4052 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4055 * Added cmd_ident, current command identifier, to the client
4056 connection context in lib/silcclient/client.h to keep track on
4057 command identifiers used in command sending. Client's command reply
4058 function handling now supports the mandatory command identifiers.
4060 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4061 funtions in client to fully support pending command callbacks.
4063 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4064 as one of the arguments to the application in the command reply
4067 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4068 before first releasing SILC but came back. Now it is removed again
4069 and should come back nomore. The FORWARDED flag was used only
4070 by the JOINing procedure by forwarding the command packet to router.
4071 Now, the JOINing procedure has been changed to more generic (due
4072 to various router environment issues) and FORWARDED is not needed
4073 anymore for anything. The protocol specification is yet to be
4076 Now, removed silc_server_packet_forward from server and the flag
4077 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4079 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Renamed NAMES command to USERS command. The NAMES was named that
4082 due to historical reasons. Now it is renamed. Also, rewrote
4083 parts of the USERS command. The nickname list is not sent anymore
4084 by the server. Only Client ID and mode lists are sent in the USERS
4085 command. Changed this also to the protocol specification.
4087 The client now resolves the names and stuff after it receives
4088 the USERS list from the server when joining to the channel.
4090 * WHOIS and IDENTIFY commands has been changed to support multiple
4091 Client ID's per command. One can now search for multiple users
4092 in the network by sending only one WHOIS or IDENTIFY command.
4093 Changed the code and the protocol specifications.
4095 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4096 uses silc_server_command_whois_parse to parse the request. */
4098 * If normal server, do not parse the WHOIS and IDENTIFY requests
4099 before sending it to the router. Saves some time.
4101 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Fixed JOIN command on client library. Wrong number of arguments
4104 used to crash the client.
4106 * Added silc_server_channel_has_global function to check whether
4107 channel has global users or not.
4109 * Added silc_server_channel_has_local function to check whether channel
4110 has locally connected clients on the channel.
4112 * The silc_server_remove_from_one_channel now checks whether the
4113 channel has global users or not after given client was removed from
4114 the channel. It also checks whether the channel has local clients
4115 on the channel anymore. If it does not have then the channel entry
4116 is removed as it is not needed anymore.
4118 * The silc_server_notify now checks on JOIN notify whether the joining
4119 client is one of locally connected or global. If it is global then
4120 the channel has now global users on the channel and that is marked
4121 to the channel entry. Also, it now saves the global client to
4122 global list who is joining and JOINs it to the channel. This is
4123 for normal server, that is.
4125 Changed silc_server_send_notify_on_channel,
4126 silc_server_packet_relay_to_channel and
4127 silc_server_packet_send_to_channel check if we are normal server
4128 and client has router set (ie. global client) do not send the
4129 message to that client, as it is already routed to our router.
4131 * Implemented LEAVE notify type handling in silc_server_notify
4134 * Tested LEAVE command in router environment successfully. Tested
4135 with two routers, two servers and two clients.
4139 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4141 * Implemented SIGNOFF notify type handling in silc_server_notify
4144 * silc_server_remove_id now removes the client entry from all channels
4145 it has joined and thusly sends SIGNOFF notify type.
4147 * Rewrote the NAMES list generation in server by removing two excess
4148 loops. The lists are created now inside one loop.
4150 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * silc_server_remove_channel_user checks now also global list
4153 for channel and client.
4155 * silc_server_new_channel_user checks now both local and global
4156 list for channel and client. Fixed a bug in client id decoding.
4157 Used to decode wrong buffer.
4159 * silc_server_channel_message checks now both local and global
4160 list for channel entry.
4162 * Tested channel joining (hence JOIN) in router environment
4163 successfully. Tested with two routers, two servers and two
4166 * Tested channel message sending in router environment successfully.
4168 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Added silc_server_save_channel_key into server.[ch] to save the
4171 received channel key in Channel Key payload processing. It is
4172 also used in JOIN command reply handling.
4174 Equivalent function silc_client_save_channel_key added into
4175 client.[ch] into client library.
4177 * Changed JOIN command reply to send information whether the channel
4178 was created or not (is existing already) and the channel key
4179 payload. Changed protocol specs accordingly.
4181 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4182 the request was sent by ID and not by nickname. Crashed on
4185 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4188 now correctly save the received data.
4190 * silc_server_free_sock_user_data now notifies routers in the
4191 network about entities leaving the network.
4193 At the same time implemented functions silc_server_remove_id
4194 and silc_server_send_remove_id to receive and send REMOVE_ID
4195 packets. The packet is used to notify routers in the network
4196 about leaving entities. The ID removed will become invalid in
4199 * Added function silc_idlist_del_server into server. Removes and
4200 free's server entry from ID list.
4202 * silc_server_private_message function now checks, if we are router,
4203 that the destination ID really is valid ID, naturally.
4205 * In router when NEW_ID packet is received (for new client) the
4206 hash of the Client ID is saved in the ID Cache but the
4207 client->nickname is set to NULL, instead of putting the hash
4210 IDENTIFY command now also checks that client->nickname must be
4211 valid. If it is not if will request the data from the server who
4212 owns the client. Added new function
4213 silc_server_command_identify_check.
4215 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4216 to set the command to already allocated Command Payload.
4218 * Tested private message sending in router environment with two
4219 routers, two servers and two clients. Fixed minor bugs and now
4222 * Fixed segfault from client's NAMES command. Used to crash if
4225 * Forwarded packets must not be routed even if it is not destined
4226 to the receiver. Changed server code comply with this.
4228 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added `require_reverse_mapping' boolean value to ServerParams
4231 structure. If TRUE (not default) the server will require that
4232 the connecting host has fully qualified domain name.
4234 If the reverse mapping is not required and hostname could not be
4235 found the IP address is used as hostname.
4237 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Implemented version string checking to both client and server.
4240 The check is incomplete currently due to the abnormal version
4241 strings used in development version of SILC.
4243 * Changed all command functions in server to use the new
4246 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Changed char *data to unsigned char *data in ID Cache system to
4249 support binary data as ID Cache data. Changed code to support
4250 binary data in lib/silccore/idcache.c.
4252 * Renamed silc_server_packet_relay_command_reply to
4253 silc_server_command_reply as it is normal packet receiving
4254 function. Rewrote the function to accept command replys for
4255 servers and not only for clients.
4257 * Mark remote router always as registered server if we are connecting
4258 to it. Otherwise, commands sent by the router to us are ignored.
4260 * All ID List find routines now returns the ID Cache Entry pointer
4261 as well if requested.
4263 * WHOIS command works now in router environment, tested with two
4264 routers, two servers and two clients.
4266 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4267 in router environment (as it is almost equivalent to WHOIS) but
4268 hasn't been tested thoroughly. Added new functions:
4270 silc_server_command_identify_parse
4271 silc_server_command_identify_send_reply
4272 silc_server_command_identify_from_client
4273 silc_server_command_identify_from_server
4275 * Disabled route cache adding because adding two different ID's with
4276 same IP replaces the old cache entry thus giving wrong route.
4277 The entry->router->connection is always the fastest route anyway
4278 so route cache may not be needed. Of course, new routes maybe
4279 established after receiving the ID when the entry->router->connection
4280 might not be anymore the most optimal.
4282 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Add route cache for received ID for fast routing.
4286 * Added silc_server_packet_route to route received packet on router
4287 that is not destined to us.
4289 * Renamed silc_server_get_route to silc_server_route_get.
4291 * Added id_string and id_string_len fields into SilcServer to
4292 include encoded ServerID for fast comparing without excess
4293 encoding of the ID's.
4295 * Cleaned up WHOIS command on server side. Added following static
4298 silc_server_command_whois_parse
4299 silc_server_command_whois_check
4300 silc_server_command_whois_send_reply
4301 silc_server_command_whois_from_client
4302 silc_server_command_whois_from_server
4304 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4305 arguments in command replies. All command functions should be
4306 updated to use this macro.
4308 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Minor typo fixes on command reply handling on server.
4312 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Added silc_server_command_add_to_channel internal routine to add
4315 the client to the channel after router has created the channel and
4316 sent command reply to the server.
4318 * Added generic silc_server_send_command to send any command from
4321 * Use static buffer with ID rendering instead of duplicating data.
4323 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Fixed a channel user mode bug when joining to a channel server gave
4326 everybody channel founder rights, oops.
4328 * We mark ourselves as the router of the incoming server connection
4329 if we are router ourselves. This way we can check in some packet
4330 sending functions whether it is locally connected server. For
4331 incoming router connections we put NULL.
4333 * For router sending packets locally means now always sending the
4334 packet cell wide; to local clients and local servers. For normal
4335 server sending packet locally means sending it to only local
4338 * Fixed the JOIN command to really work in router environment. If the
4339 channel is created it is always created by the router. Router is
4340 also responsible of making the initial joining to the channel,
4341 sending JOIN notify to the sending server and distributing
4342 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4343 does not exist server doesn't do anything else but forward the
4344 command to the router which performs everything.
4346 * Added silc_server_send_channel_key function to send the Channel Key
4349 * Added silc_server_create_channel_key to create new channel key. The
4350 channel key is now re-generated everytime someone joins or leaves
4351 a channel, as protocol dictates. Note: channel->key_len is the
4354 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4357 packet_receive.[ch] to separate packet sending and receiving
4358 routines. The server.[ch] now includes everything else including
4359 actual packet processing (writing and reading data) and other
4362 Renamed silc_server_private_message_send_internal to
4363 silc_server_send_private_message. The routine is still though
4364 used only to relay private messages as server does not send
4365 private messages itself.
4367 Renamed silc_server_new_channel to silc_server_create_new_channel
4368 and added new function sicl_server_new_channel that handles the
4369 incoming New Channel packet. Added also new sending function
4370 silc_server_send_new_channel to send New Channel Payload.
4372 * Added new function silc_server_notify to process incoming notify
4373 packet to the server/router. Server may then relay the notify
4374 to clients if needed.
4376 * Added new function silc_server_new_channel_user to process incoming
4377 New Channel User packet. Router will redistribute the packet and
4378 send JOIN notify to its local clients and locally connected servers
4379 if needed. Normal server will send JOIN notify to its local client
4380 on same channel when received this packet. Added also corresponding
4381 sending function silc_server_send_new_channel_user to sent the
4384 * Added boolean route argument to send_notif_to_channel and
4385 packet_send_to_channel functions to attempt to route the packet
4386 if it is TRUE and send only locally if it is FALSE.
4388 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * silc_server_replace_id now broadcasts the received replace ID
4391 packet if it is not broadcast packet already. The router must
4392 broadcast to inform other routers about changed ID.
4394 * Added backpointer to server's router into SilcServer context in
4395 silcd/server_internal.h.
4397 * Fixed silc_server_packet_broadcast to send correct broadcast
4400 * The channel key is now distributed to the local client as soon
4401 as it is received from the router (in router environment) so that
4402 no other packet may be sent for the channel until client has
4405 * silc_server_remove_channel_user now broadcasts the received
4406 Remove Channel User packet if it is not broadcast packet already.
4407 The router must broadcast to inform other routers about removed
4410 * Added users field into SilcPacketContext that is a reference count
4411 of the context. One can increase the reference count by calling
4412 silc_packet_context_dup which is now changed to just increase the
4413 reference count instead of duplicating the data. The reference
4414 count is decresed by calling silc_packet_context_free that will
4415 free the data after the reference count hits zero.
4417 For now on the packet context and everything allocated into it
4418 (including the raw packet from network) must be freed by calling
4419 the new silc_packet_context_free function. Added also new function
4420 silc_packet_context_alloc that must be used now to allocate the
4421 context. This also means that if a routine is asynchronous from
4422 silc_[client/server]_packet_parse_type the packet context must
4423 be duplicated by calling silc_packet_context_dup. Otherwise it
4424 gets free'd after silc_[client/server]_packet_parse_type returns.
4425 Also, one must remember that if packet is duplicated then its
4426 reference count must be decresed by calling the free function as
4427 many times as it was duplicated.
4429 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4430 from both client and server.
4432 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Made joining to a channel working in router environment.
4436 * Cleaned up JOIN command on server side and create function
4437 silc_server_command_join_channel internal routine to make the
4440 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Changed silc_command_pending list to SilcDList. Also, added
4443 `ident' field to SilcServerCommandPending structure to identify
4444 the reply and to call correct callback.
4446 Added silc_server_command_pending_check function to replace the
4447 corresnponding macro. The silc_command_pending list is not
4450 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4451 to set identifier to previously allocated Command Payload. It
4452 is used to set identifier for command when resending Command
4455 * Added silc_command_payload_encode_payload to encode Command
4456 Payload buffer from SilcCommandPayload structure.
4458 * Added silc_argument_payload_encode_payload to encode Argument
4459 payload buffer from SilcArgumentPayload structure.
4461 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Changed WHOIS command to support router connection on server side.
4464 The whois request is always sent to router unless the server is
4465 standalone server. After server has received the reply from the
4466 router will it send the reply to the client.
4468 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4469 broadcast received broadcast packet. The function is used only
4470 by router. The broadcast packet is always sent to the router's
4473 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4474 render given ID to printable string, for log files for example.
4476 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Made basic router to router connections working. At least they
4479 can now connect to each other but nothing really works the way
4480 they are supposed - yet.
4482 * Added new initiator token to RouterConnection configuration
4483 file in silcd/serverconfig.[ch]. It is used to tell whether we
4484 are the initiator to the remote router or whether we'll expect
4485 the other end to connect.
4487 * Moved registering of listener task to silc_server_init, hence
4488 the server starts listenning as soon as it is run, even if it
4489 does not have connections to other routers. Let's see how well
4492 * Changed default connection retry timeouts for more suitable in
4495 * Removed cipher and such arguments from silc_idlist_add_client
4496 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4497 Added new function silc_idlist_add_data to add the keys and stuff
4500 * Added SilcIDListData structure and added it to SilcClientEntry
4501 and SilcServerEntry as their first field in the structure. This
4502 way we can explicitly cast the ID entries to the SilcIDListData
4503 structure and get common data for the entries. In past, we had
4504 to first check what type of connection it is and then cast it to
4505 correct ID entry type. Now, we can directly cast the opaque
4506 pointer to the SilcIDListData (no matter what ID entry it actually
4507 is) and get the data needed.
4509 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4512 in some circumstances even if threre were timeout tasks, though not
4513 IO tasks, but tasks anyway. Now fixed.
4515 * Defined SilcServerConnection structure to hold connection specific
4516 stuff about directly connected servers and routers. The definition
4517 is currently in silcd/server_internal.h. I thought about having
4518 a bit more important role fro this struct but for now it is used
4519 only when connecting to other server (or router actually).
4521 * Added connecting retry support in server when connecting to
4522 router(s). The retry feature implement exponential backoff
4523 algorithm. Also, added SilcServerParams structure to hold default
4524 parameters for server. For now, it include these retry settings
4525 and are hard coded. After server is moded to be as Silc Server
4526 Library this structure will be more important.
4528 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Changed client librarys channel->clients table to SilcList and
4531 changed code accordingly.
4533 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * Changed client's channel table to SilcList and changed code
4536 accordingly. Also changed SilcChannelClientEntry to include back-
4537 pointer to the channel so that client entry can use that structure
4538 as list as well and we have fast cross-reference to the channel.
4539 This change dramatically decreased the complexity of channel
4540 handling with client entry and vice versa (removed one extra
4541 loop when searching for channel entry from many functions).
4543 * Changed server->sim from table to SilcDList and changed code
4546 * NAMES command can now be used from user interface. It will show
4547 the user list on the channel, neatly.
4549 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4550 Code now saves realname of the user if it becomes available.
4552 * Renamed configure.in to configure.in.pre and made ./prepare
4553 script to automatically add correct version string to
4554 configure.in which it creates from configure.in.pre.
4556 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * NAMES command reply now shows users mode with the nickname when
4561 * Moved silc_client_ch[u]mode[_char] functions from
4562 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4563 place sucks, they are utility functions and should be in some
4566 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4568 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4571 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added TRQ (efficient deque and list library) into lib/trq. This is
4576 a very good list library that is currently used in the SILC. Defined
4577 SilcList API over the library because I didn't like the API very
4578 much. See lib/trq/silclist.h for the API and examples of how to
4579 use the API. Fixed various places in the code to use the new
4580 SilcList API. The SilcList is meant for lists that has a structure
4581 already defined as a list. It is not suitable to add just some
4582 context to the list (in TRQ, the context is the list actually).
4584 So, I defined SilcDList that can be used for the purpose where
4585 predefined list structure does not exit. This can be used as
4586 such list. Now some context just can be added to the SilcDList.
4587 Currently this list is not used in the SILC just yet, though there
4588 are a lot places where this can replace dynamically allocated
4589 tables and I will fix these places, later, to use SilcDList.
4590 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4591 and use TRQ internally).
4593 Also fixed some annoying warning messages that the original TRQ
4594 code generated. Also minor changes to TRQ's Makefile.in.
4596 * Added support for querying by Client ID to both WHOIS and
4597 IDENTIFY commands into server, as required by the protocol.
4599 * Removed method function pointers from SilcBuffer structure. They
4600 weren't used to anything and just increased the context size for
4601 no good reason. This change also made silc_buffer_alloc and
4602 silc_buffer_free functions inline functions.
4604 * Disabled command flooding detection support until it's fixed so
4605 that it accepts commands in but does not execute them more than once
4608 * Added silc_net_localhost(), to return local hostname, into
4609 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4610 that must be initialized before calling silc_client_init.
4612 * Added new function: silc_server_send_notify_on_channels to send
4613 notify messages to all channels client has joined. It is assured
4614 that the message is sent only once per client.
4616 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4617 lib/silcutil/silcutil.[ch] as silc_format function. The new
4618 function is generic and is used by server as well, not only by
4619 the logging routines.
4621 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4622 the provided version string was not acceptable. Added new function:
4623 silc_ske_check_version into lib/silcske/silcske.h. The function
4624 must be implemented by the application (client or server) and it
4625 does not reside in the SKE library. The function checks the version
4626 string remote end sent.
4628 * Added back pointers (to opaque context and to SilcSocketConnection)
4629 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4631 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4632 duplicate packet context structure.
4634 * Changed `notify' client operation to send same arguments as client
4635 receives from server except for ID's. ID's are mapped to correct
4636 ID entry and that is returned. Also, if channel entry is not sent
4637 by server but the notify is for channel the channel entry is sent
4638 to application (otherwise application doesn't know that it is for
4639 channel (library gets it from packet's Destination ID)).
4641 * Added silc_client_remove_from_channels into client library to
4642 remove a client from all channels it has joined to. Used when
4643 received SIGNOFF notify from server. Added also new function
4644 silc_client_replace_from_channels to replace old ID entry with
4645 new ID entry on all channels. Used when received NICK_CHANGE
4648 * Fixed ID Cache list handling in silc_idlist_get_client in
4649 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4650 to get (or query) client by ID.
4652 * Updated TODO list.
4654 * Added connection authentication status message defined by the
4655 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4656 support for these into the code in client and server side.
4658 * Added generic function silc_client_send_command to send any command
4659 with variable argument list. Application should use this function
4660 to send commands if the command functions provided by the library
4661 does not suite for the application's user interface needs.
4663 * Added new `failure' client operation. Application is notified about
4664 received failure packet if client is executing a protocol. In this
4665 case the protocol's execution has failed.
4667 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4668 is required by the protocol.
4670 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4671 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4674 * Added status flag to SilcSKE object to indicate realtime status
4675 of the SKE protocol.
4677 * Application receives now exactly same command reply arguments as
4678 the library receives from server. However, if ID is received the
4679 corresponding ID entry is returned to the application (eg. Client
4680 ID is mapped to correct SilcClientEntry entry and that is returned).
4681 Changed command_reply client operation due to this change.
4683 * Changed all ID's in commands and in command replys as ID Payloads.
4684 Change affected both client and server side codes.
4686 All ID's sent in SILC network (with execption of ID's in SILC
4687 Packet header) are sent in ID Payload to support variable length
4690 * Server now notifies nick changes and notifies all clients on
4691 the channels about the new nickname (about the new Client ID,
4694 * Implemented CMODE command to change channel modes. Supports all
4695 channel modes defined by the protocol specs except ban and invite
4696 lists. (Also, private channel key mode is supported but support for
4697 setting private channel key in client is missing, thus, this mode
4698 has no effect on client side (except that server requires that the
4699 client uses private channel key and normal channel traffic does not
4702 Also, invite mode works per se, but INVITE command does not work
4703 yet correctly, so you can set channel as invite only channel but
4704 inviting clients to the channel does not work (it is yet to be
4705 thought what's the best way to do it).
4707 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4708 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4709 Implemented CUMODE command to change user's mode on the channel.
4710 Supports all modes defined by the protocol specs.
4712 * Added NAMES command reply to return users modes on the channel.
4714 * Removed unnecessary and slow ciphers from lib/silccrypt.
4716 * Set SO_KEEPALIVE option to connection sockets by default.
4718 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4720 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4721 redefined the Notify Payload into protocol specs.
4723 * Added silc_id_payload_parse_id to get ID directly from raw
4726 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4729 accept searching by Client ID as well.
4731 * Added support for LEAVE and SIGNOFF notify types in client library.
4733 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4734 to parse ID Payload from raw data.
4736 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added flags parameter into silc_ske_assemble_security_properties
4739 function in lib/silcske/silcske.[ch].
4741 * Changed notify client operation to fit better for notify messages
4742 sent by server. The notify payload received from server is now
4743 passed to the application (after parsing it to SilcNotifyPayload).
4744 It is application's responsibility to retrieve the arguments
4745 from the payload and show the message the way it wants. The message
4746 sent by server is implementation specific.
4748 * Changed public keys to comply with the protocol specification.
4749 Old public keys are not supported anymore and are not compatible.
4751 * Removed nickname from Channel Payload as the latest draft removed
4752 it. The client must resolve the nickname from the NAMES command
4753 reply received when it joined the channel.
4755 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4757 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Fixed some errors in protocol specification drafts.
4761 * Created lib/silccore/silcnotify.c to implement Notify Payload
4762 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4763 generic payloads described by protocol specifications. The file
4764 includes implementations for ID Payload and Argument Payload.
4766 * Changed Command Payload implementation to use the new Argument
4767 Payload. Changed command_xxxx_payload to command_payload_xxxx
4768 to comply with SILC coding conventions.
4770 * Added suppport for Argument Payload handling in Notify Payload
4771 implementation as protocol requires it. Added the new support
4772 into server and client lib as well.
4774 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Added support for multiple nicknames on same channel. [n] is
4777 added locally to the nickname if there are more than one same
4778 nicknames on the channel.
4780 * Server now sends all nicknames that matched WHOIS request.
4781 Client also shows the list received from server.
4783 * Added TOPIC command to client side. User can now set and show
4784 current topic on channel.
4786 * Added MOTD command to client and server. Also, server sends the
4787 motd when client connects to the server.
4789 * Changed version strings to comply ISO 8601.
4791 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Fixed protocol error handling in client library. It should now
4794 cope even if the SKE fails for some reason.
4796 * Made new protocol specification drafts for submitting to IETF.
4798 * Implemented TOPIC command to server in silcd/command.c.
4800 * Added two new notify types into lib/silccore/silcnotify.h:
4801 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4802 notify nickname change and topic setting/change on a channel.
4804 * API change of command_reply operation in client library. The
4805 application gets now the status type received from server as well.
4807 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4811 * Cras fixed and optimized the packet handling even further and
4812 it should work now. Minor change to the prototype of function
4813 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4815 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Added new function into lib/silcutil/silcschedule.[ch]:
4818 silc_schedule_with_fd to select() a specified fd. The function
4819 returns after timeout expires or data arrives or goes. The
4820 function is used by packet routines to wait that all data is
4821 received from network.
4823 * Fixed data reading from network in lib/silccore/silcpacket.c.
4824 The code now assures that all data is read from the fd and then
4825 continues packet processing. This was a bug fix since the code
4826 used to drop some data in some circumstances.
4828 * Added new function into lib/silcclient/client.[ch]:
4829 silc_client_start_key_exchange to start key exchange after
4830 connection has been established to server. The code internally
4831 now uses this funtion but its main purpose was to provide it
4832 for applications that perform their own connecting. After
4833 application has created a connection it merely calls this
4834 function to start the key exchange between client and server.
4835 The library takes care of everything else after that.
4837 Updated also lib/silcclient/README to explain the usage of
4840 * Do not send to application information that connection has
4841 been established. Application gets notified it by connect
4844 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Applied cras's patch to add silc_schedule_one function. The
4847 function runs scheduler once and returns.
4849 * Fixed the scheduler after cras messed it up. The timeout
4850 handling works now as it's supposed to work.
4852 * Added into lib/silccore/ silcnotify.h to include notify
4853 message types support. Changed silc_server_send_notify*
4854 functions, in server.[ch], to support those new notify types.
4855 Added the support for the notify types into client library,
4856 as well. Added new notify client operation into ops.h in
4859 * Changed silc_server_packet_send_to_channel to send normal
4860 packets instead of just channel message packets. The function
4861 is now used to send the notify packets to channels. It is not
4862 used to send channel message packets anymore, as server never
4865 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4866 va_arg()s as it seems to require it nowadays. I guess, if SILC
4867 is compiled with older va_arg() the new code should work anyway.
4869 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Splitted core library. Core library (lib/silccore) includes
4872 now only SILC protocol specific core (and common) components.
4873 Created new utility library (lib/silcutil) that includes more
4874 generic purpose stuff. The stuff for util library was taken
4875 from the old core library. This was minor and easy split.
4877 * Created SILC Client Library (lib/silcclient) that includes
4878 implementation of the SILC client without user interface. This
4879 was major move from silc/ directory. The code has been changed
4880 so that it is transparent towards the user interface. The
4881 silc/ directory includes now the same user interface as before
4882 and it uses the new client library. Read lib/silcclient/README.
4883 Basicly, the client library performs everything else related
4884 to SILC except user interface handling. Also, configuration
4885 files are considered to be part of user interface and library
4886 does not handle them.
4888 This change also changed a lot of structures, function naming etc.
4889 Most important change was that SilcClientWindow object was
4890 renamed to SilcClientConnection in the client library. Created
4891 also new file lib/silcclient/ops.h. Also added new files
4892 silc/local_command.[ch] and silc/client_ops.[ch].
4894 All these changes were made to make it easier for user interface
4895 designers to create what ever user interface for the SILC client
4898 It is also expected that the server will be moved to lib
4899 directory as well and SILC Server Library will be created;
4900 sometimes in the future.
4902 * Removed Local commands from lib/silccore/silccommand.h as
4903 they are application specific and new client library does not
4904 handle any of those anymore.
4906 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4907 old client implementation in silc/.
4909 * Added support for callback functions in SILC_LOG_* macros.
4910 Application can now set its own callbacks that will be called
4911 instead of using the default functions that will always print
4912 the debug messages to stderr (or stdout). Also, debugging can
4913 now be disabled by setting silc_debug to FALSE and re-enabled by
4914 setting it to TRUE. Note, that logging will still work even
4915 if debugging is disabled.
4917 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4918 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4919 silc_log_reset_debug_callbacks.
4921 * To enable debugging in silc client one must give now -d
4922 option on command line.
4924 * Changed silc_schedule_init to automatically allocate task queues
4925 if they are not allocated before calling it.
4927 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Added GMP 3.1 into math library.
4931 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4934 a channel in SILC network. The packet is used by servers and
4935 routers to notify other routers that user has left a channel.
4936 This little feature was missing until now. Added the feature
4937 to protocol specification as well.
4939 Added functions: silc_server_send_remove_channel_user and
4940 silc_server_remove_channel_user into server.[ch].
4942 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4943 lib/silccore/silcpacket.h. However, they are not implemented
4946 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Fixed joining to a channel and sending channel messages
4949 between server and router. The channel message sending should
4950 now work inside a cell.
4952 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Fixed the private message sending between server and router.
4955 The private message sending should now work inside a cell.
4957 * Added silc_server_replace_id into server.[ch] to replace
4958 existing ID in the SILC network.
4960 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4961 and silc_idlist_replace_server_id into idlist.[ch] in server.
4963 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Fixed the server to server connections. Server can again now
4966 connect to router. Router to router connections probably does
4969 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Added dynamic protocol registering support. Now protocols can
4972 registered and unregistered on the fly. Patch by cras.
4974 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Added lib/contrib directory to hold routines that some platforms
4977 don't have but are needed by SILC.
4979 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4980 into lin/contrib to provide getopt() and getopt_long() for
4981 those who don't have it.
4983 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Added AWAY command to client. When away message is set and
4986 client receives a private message packet the client automatically
4987 replies to the sender with the away message.
4989 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4990 bug seemed to be the cause of recent problems when compiling
4993 * Added version detection support to SKE protocol specification
4994 and added the new changes to the SKE implementation as well.
4995 There were other minor changes in the SKE protocol as well.
4997 Many changes in lib/silcske/silcske.[ch] and in
4998 lib/silcske/payload.[ch].
5000 * Added ^U functionality, clear input line. Patch from cras.
5002 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Mainly small bugfixes on core library. Fixed some debugging
5005 logging and buffer overflow in silclog.c.
5007 * Updated config.sub and config.guess on the distribution tree.
5009 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added command lagging support in server. Client may execute
5012 commands now only once in two seconds.
5014 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Optimized packet reception. MAC computation and checking is now
5017 also more optimized. A lot previously duplicated code is now
5018 used as generic by both client and server.
5020 * Fixed key pair generation in clientutil.c
5022 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Added into lib/silccore/silcbufutil.[ch] new function;
5025 silc_buffer_realloc.
5027 * Moved generic packet sending/encryption functions to
5028 lib/silccore/silcpacket.[ch] from client and server. Some
5029 rewriting of the functions.
5031 * Moved all generic packet reception/decryption functions to
5032 lib/silccore/silcpacket.[ch] from client and server. The
5033 packet processing is now much cleaner in both client and server.
5034 These were major changes in both client and server.
5036 * Created many common functions in server to do packet sending.
5037 Previously code were duplicated a lot, this has been removed
5040 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Rewrote major parts of the ID cache system. Don't know
5043 whether it is better now or not but at least the API is more
5046 * Major rewrite on ID cache stuff on client because of the ID
5047 cache API changes. Added idlist.c to client.
5049 * Also major rewrite on ID cache stuff on server as well.
5050 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5051 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5052 in hand, instead they are all put into the ID cache system now.
5053 All server_idlist_* routines uses ID cache now instead of
5054 traversing its own lists (those lists does not exist anymore).
5055 SilcIDList though still exists. Also, SilcXXXEntry's are
5058 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Finally made the SKE implementation compliant to the protocol
5061 specification. All mp integers are now binary encoded as
5062 opposed being HEX encoded.
5064 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5067 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5068 functions: silc_[encode/decode]_pem. Also added function
5069 silc_encode_pem_file to PEM encode with newlines ('\n') for
5072 * SILC public keys are now encoded either PEM or binary. Same
5073 option is for private keys as well. By default private keys
5074 are binary encoded and public keys PEM encoded. Silly HEX
5075 encoding were removed.
5077 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5078 function to create fingerprints.
5080 * Fixed a bug in SHA1; does not change the original data anymore.
5082 * Partly implemented INFO command on client and server side.
5083 Fixed CLEAR command. Changes to SERVER command; show current
5084 server(s) when giving command without arguments. Added
5085 VERSION command to client.
5087 * Added check to server that unregistered connections cannot
5088 execute commands (unless it is specificly allowed).
5090 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Fixed screen refresh.
5094 * Fixed channel joining bug from client. On some circumstances
5095 client tried to join to a channel it had already joined.
5097 * Added public key verification process into client's protocol.c.
5098 The client now verifies the public key from user and saves
5099 it into ~./silc/serverkeys/ directory.
5101 Added into: clientutil.[ch]: silc_client_verify_server_key.
5103 * Changed SKE protocol's silc_ske_initiator_finish function
5104 to accept callback function that verifies the received public
5105 key. Removed old silc_ske_verify_public_key function.
5107 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5110 silc_pkcs_private_key[_data]_set.
5112 * Made the password and public authentication more cleaner in
5113 server's protocol.c.
5115 * Removed historic and obsolete protocol `channel_auth' from
5116 both client and server.
5118 * Removed wrong way of sending command status messages from
5119 server to client in server's command.c. The old way violated
5120 protocol specification.
5122 Changes to silccore/silccommand.[ch]: removed
5123 silc_command_encode_status_payload -> not needed anymore,
5124 changed silc_command_encode_payload_va to accept extra
5125 argument on variable argument list. The argument type must
5126 now be provided to the function. Also, added new function:
5127 silc_command_encode_reply_payload_va which is same as
5128 normal command_encode_payload_va except command status type
5129 is provided as extra argument.
5131 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Added ~./silc directory handling. The directory includes the
5134 public and private keys for the client.
5136 Added silc_client_check_silc_dir, silc_client_create_identifier
5137 and silc_client_load_keys.
5139 * Implemented SILC protocol compliant public key. Added public
5140 and private key saving to and loading from files.
5142 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5143 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5144 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5145 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5146 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5148 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5149 silc_pkcs_load_[public/private]_key.
5151 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Added silc_server_get_route (route.[ch]) to get connection
5154 data for the fastest route for given ID.
5156 * Implemented INVITE command on client and server. The command
5157 were re-defined in the SILC Protocol Specification and the
5158 implementation now complies with the specification.
5160 * Implemented PING command on client and server.
5162 * Implemented NAMES command on client and server. The server side
5163 supports currently only normal server not router server yet.
5164 Some changes to NAMES definition in SILC protocol specification.
5166 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Implemented LEAVE command on client and server.
5170 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5171 again. This change was made to the protocol as well. Server
5172 should not violate the protocol specification anymore.
5174 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5177 was tested. SOCKS4 was not but should work anyway.
