3 * Fixed the KICKED notify handling in client library to
4 correctly remove the channel and all entries from the
5 channel when I was kicked. This bug crashed the client.
7 Fixed yet another but in KICKED notify handling to remove
8 the kicked client correctly from the channel.
10 Affected file is lib/silcclient/client_notify.c.
12 * Fixed a minor bug in looking up correct client entry
13 in KICKED notify in server. Affected file is
14 silcd/packet_receive.c.
16 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
17 sources correctly to distribution. Fixes --with-gmp option.
19 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
21 * Fixed a bug in the silc_client_nickname_format function that
22 handles the multiple same nickname formatting. Two clients
23 with same nickname caused problems after the first one left
24 and rejoined. It didn't format the nickname correctly.
25 Affected file is lib/silcclient/idlist.c.
27 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
29 * Don't change the topic if olod topic is same as new one.
30 Affected file is silcd/packet_receive.c.
32 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
34 * Added cross-reference support to the SILC Documentation
35 generator. All types across all HTML files are now cross-
36 referenced. Affected files util/robodoc/generator.c and
37 scripts/silcdoc/silcdoc.
39 * Added file lib/silcutil/silctypes.h to include all the
40 arithmetic type definitions and some macros. Removed
41 includes/bitmove.h and moved macros to silctypes.h.
43 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
47 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
49 * Added `type' argument to silc_id_payload_parse_id function which
50 now returns the type of the ID to the sent pointer. Affected
51 file is lib/silccore/silcid.[ch].
53 * Added check for CMODE_CHANGE notify type that mode change is
54 allowed by the sender. Affected file silcd/packet_receive.c.
56 * Added check for CUMODE_CHANGE notify type that mode change is
57 allowed by the sender. Affected file silcd/packet_receive.c.
58 Added the ID type as CUMODE_CHANGE notify type as argument
59 to the `notify' client operation. Affected files are
60 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
62 * Added function silc_client_add_server to the client library.
63 Added support for resolving also channel and server info when
64 received unknown entity in notify packet. Affected files are
65 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
67 * Added function silc_command_get_status to return the command
68 status from the command reply's argument payload. Affected files
69 are lib/silccore/silccommand.[ch].
71 * Added check for KICKED notify type that the kicking is
72 allowed by the client. Affected file silcd/packet_receive.c.
74 * Created function silc_get_input which can be used to get input
75 (echo on or off) from user on command line. Affected files are
76 lib/silcutil/silcutil.[ch].
78 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
80 * Optimized silc_server_packet_relay_to_channel function.
81 Added new function silc_channel_message_payload_encrypt which
82 can be called directly if channel message payload needs to
83 be encrypted and is already encoded (no need to call _encode
84 function). Packet relaying is now done by router without any
85 extra memory allocations. Affected files are
86 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
89 * Fixed the INVITE notify handling. It took wrong arguments
90 as invite list and invite delete. Affected file is
91 silcd/packet_receive.c.
93 * Added check for TOPIC_SET notify type that the topic change is
94 allowed by the client. Affected file silcd/packet_receive.c.
96 * Added check for INVITE notify type that inviting is allowed by
97 the client. Affected file silcd/packet_receive.c.
99 * Changed the silc_server_client_on_channel to return the
100 SilcChannelClientEntry as well. Moved the function
101 silc_server_check_cmode_rights to server_util.[ch].
102 Affected files are silcd/server_util.[ch], silcd/command.c.
104 * Added function silc_server_check_umode_rights to check whether
105 changing client's user mode is allowed. Added check for
106 UMODE_CHANGE notify type that the umode change is allowed
107 by the client. Affected files are silcd/server_util.[ch],
108 silcd/packet_receive.c and silcd/command.c.
110 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
112 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
113 ID length. It ignored that ID can be IPv6 based as well.
114 Affected file lib/silccore/silcpacket.h.
116 * Fixed the silc_id_id2str and silc_id_str2id to take the
117 IPv6 address offset's into consideration. Affecte file is
118 lib/silccore/silcid.c.
120 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
122 * Fixed the internal Unix scheduler functions to check for
123 NULL context they may receive. The affected file is
124 lib/silcutil/unix/silcunixschedule.c.
126 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
128 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
129 can specify different directory with --home command line
130 parameter. Affected files irssi/src/silc/core/client_ops.c,
133 * SILC-specific commands aren't now executed if the active server
134 isn't of SILC-type, so there won't be problems with having
135 IRC and SILC protocol support in same client. Affected files
136 irssi/src/silc/core/silc-channels.c, silc-servers.c,
139 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
141 * Improved the signal support in SILC Schedule. Added new
142 function silc_schedule_signal_call which is used by application
143 to mark a signal to be called. It is now safe to perform
144 any kind of tasks in signal callbacks since it is guaranteed
145 that the application specified signal callback is called
146 after the signal is over. Affected files are
147 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
149 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
151 * Added `name' field to SilcChannelPrivateKey to represent
152 application given name for the key. Moved also the context from
153 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
154 Added the `name' argument also to the function
155 silc_client_add_channel_private_key.
157 Added function silc_client_current_channel_private_key to set the
158 current channel private key in use.
160 Added "change" command to KEY command which can be used to change
161 the current channel private key. Bound the command also to
164 Also affected files lib/silcclient/client_channel.c,
165 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
167 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
169 * Added silc_rng_get_byte_fast function in to the
170 lib/silccrypt/silcrng.[ch].
172 * Changed the interface of silc_packet_assemble and the
173 silc_packet_send_prepare. If silc_packet_assmble is now
174 called the application does not call silc_packet_send_prepare
175 because the library will call it automatically. These
176 interfaces now also return a reference to the outgoing buffer
177 which includes the assembled packet, which the application can
178 use to encrypt the packet.
180 Affected files are lib/silccore/silcpacket.[ch],
181 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
182 silcd/packet_send.c, server_backup.c and packet_receive.c.
184 * Fixed a packet sending bug on very high load, where outgoing
185 packet queue wasn't handled correctly and packets got corrupted.
186 Affected files are lib/silcutil/*/silc*sockconn.c,
187 lib/silcclient/client.c and silcd/server.c.
189 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
191 * Added macro SILC_PACKET_DATALEN which can be used during
192 packet assembling to check whether the data to be added to
193 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
194 len is truncated until it fits it.
196 Added checks for maximum length of channel message payload and
197 private message payload also.
199 Added checks for maximum packet length in server and in
202 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
203 lib/silcclient/client.c, lib/silccore/silcchannel.c and
204 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
205 lib/silcclient/client_prvmsg.c.
207 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
209 * Added silc_server_packet_queue_purge call to the
210 silc_server_disconnect_remote to assure that all data in the
211 queue before disconnecting is sent to the network. Affected
214 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
216 * Added the deleting of server's own ID cache entry to the
217 silc_server_free function. Free also everything else that
218 has been allocated in silc_server_init. The affected file
221 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
223 * Added functions silc_parse_version_string, silc_version_to_num,
224 and silc_ske_parse_version to parse SILC protocol style version
225 strings. Affected files lib/silcutil/silcutil.[ch] and
226 lib/silcske/silcske.[ch].
228 * Added new configuration params: version_protocol, version_software
229 and version_software_vendor to specify what version the remote
230 host must at least be to be able to connect to server. The vendor
231 string can be regex matched too. Added new function
232 silc_server_connection_allowed to check maximum number of allowed
233 connections, and allowed versions for incoming connections.
234 Affected files are silcd/server.c, server_util.[ch] and
237 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Added preliminary support for signals in scheduler. The
240 signals we care about are now blocked always when the scheduler
241 is locked. This way we can synchronise the use of signal with
242 scheduler. It is guaranteed that when signal occurs the scheduler
243 is not locked, and thus new tasks can be safely added to the
246 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
247 to silc_schedule_internal_init and silc_schedule_internal_uninit.
248 Added new platform specific routines
249 silc_schedule_internal_signals_[un]block and
250 silc_schedule_internal_signal_[un]register.
252 Added new functions to SILC Schedule API:
253 silc_schedule_signal_[un]register. Each signal that application
254 is going to use should be registered to the scheduler.
256 Affected files are lib/silcutil/silcschedule.[ch],
257 lib/silcutil/*/silc*schedule.c.
259 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
261 * Check for unauthenticated client and server in the
262 silc_server_new_client and silc_server_new_server functions.
263 Affected file silcd/packet_receive.c.
265 * Added function silc_string_is_ascii to check whether given
266 string is 7-bit ASCII string. Affected files are
267 lib/silcutil/silcutil.[ch].
269 * Added function silc_id_is_valid_server_id into the
270 silcd/serverid.c and added checking for valid Server ID's in
271 silc_server_new_server. The Server ID must always be based
272 on the server's public IP address.
274 * Added logging of DISCONNECT packet message in the server.
275 Affected file silcd/server.c.
277 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
279 * Changed all library interfaces that use Global RNG to also
280 accept SilcRng as argument. Affected files are
281 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
282 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
283 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
284 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
287 * Added function silc_pkcs_generate_key to the
288 lib/silccrypt/silcpkcs.[ch] for applications so that they
289 don't need to do pkcs->pkcs->init calls anymore.
291 * Remove SilcSocketConnection from the SFTP API since it really
292 wasn't needed there. The application has the information
293 saved in its contexts anyway and the SFTP layer doesn't need
294 know about it. Affected files lib/silcsft/silcsftp.h and
295 lib/silcsftp/sftp_[server/client].c.
297 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
298 The SilcSimContext is not SilcSim.
300 * Fixed possible buffer overflows in silc_id_render in the
301 lib/silcutil/silcutil.c.
303 * On EPOC the global crypto module lists are not used at all
304 in the crypto library. Added support for using the constant
305 algorithm list on EPOC. Affected files are
306 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
309 * Fixed the handling of third parameter of KICKED notify, since
310 it was mistakenly updated to SILC Protocol 1.0 even though it
311 is to be included in 1.1. Since it is not in 1.0 it is not
312 mandatory, and this fix now handles it only if it is provided,
313 and it is not error if it is not provided. Affected file
314 lib/silcclient/client_notify.c.
316 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
318 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
319 client. Affected file irssi/src/silc/core/client_ops.c.
321 * Merged with Irssi 0.8.4 from irssi.org CVS.
323 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
325 * Check for valid socket connection in client entries before
326 sending any messages. Fixes a crash, but doesn't fix some
327 other underlaying bug that is lurking there. Affected
328 file silcd/packet_send.c.
330 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
332 * $usermode, $cumode and $cumode_space expandos shouldn't do
333 anything with non-SILC server records. Affected file
334 irssi/src/silc/core/silc-expandos.c
336 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
338 * Fixed the silc_net_check_[host/local]_by_sock to support
339 IPv6 bound sockets as well. Now they can return IPv6 addresses
340 as well. Affected file lib/silcutil/silcnet.c.
342 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
343 Affected lib/silcutil/unix/silcunixnet.c.
345 * Fixed ID rendering (at least on some platforms, not NetBSD)
346 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
348 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
350 * Added silc_hash_public_key and silc_hash_public_key_compare
351 functions to be used with SilcHashTable. They can be used to
352 hash public keys and compare public keys in hash table. Affected
353 file lib/silcutil/silcutil.[ch].
355 * Added support for specifying multiple public keys for Client
356 connection section in server configuration file. This makes it
357 possible to accept multiple public keys from same host, or to
358 make a section that accepts any incoming host, and have the
359 accepted public keys listed in the section.
361 Added functions silc_sever_[find/get]_public_key, added the
362 support for this actually to all connection sections but only
363 the Client section is currently allowed to specify multiple
366 Affected files are silcd/server.c, server_internal.h,
367 command.c, protocol.c, server_util.[ch], packet_receive.c.
369 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
371 * Merged Irssi 0.8.2 from irssi.org CVS.
373 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
375 * If silc_debug is TRUE, also output standard logging messages
376 to stderr with the debug output.
378 Made silc_log_reset_all() flushing all channels before returning.
379 Also fixed some documentation typos.
381 Affected files are lib/silcutil/silclog.[ch].
383 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
385 * Fixed the server to check correctly the amount of connections
386 from single host, by checking also the type of the connection.
387 Fixed also the comparison of number of connections and number
388 of allowed connections. Affected files are silcd/server.c,
391 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
393 * Fixed the USERS command reply to save the user's mode on the
394 channel as well. Fixed JOIN command reply to check whether a
395 client is on channel already and not join it twice. Affected
396 file lib/silcclient/command_reply.c.
398 * Added new file silc-expandos.c into irssi/silc/core/ to return
399 various stuff for various signal for the statusbar etc. updating.
400 Now Irssi SILC client prints channel user modes etc. on the
403 * The user mode (like server/router operator changes) is now shown
404 on the Irssi SILC client's statusbar. The affected files are
405 irssi/src/silc/core/client_ops.c, silc-expandos.c.
407 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
410 to SILC_SCHEDULE_[UN]LOCK macros.
412 * Added more error printing to logs in server code. Affected
413 files silcd/server.c and silcd/protocol.c.
415 * Fixed -S option parsing in Irssi SILC Client. Affected file
416 irssi/src/silc/core/silc-core.c.
418 * Added silc_buffer_alloc_size function. Affected file is
419 lib/silcutil/silcbuffer.h.
421 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
423 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
424 constants. Affected files in
425 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
428 * Changed the internal SFTP Memory FS table to const. Affected
429 file lib/silcsftp/sftp_fs_memory.c.
431 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
433 * Fixed the buffer formatting and unformatting routines to
434 check the size of 64 bits types with sizeof(). Affected
435 file is lib/silcutil/silcbuffmt.c.
437 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Removed 0.6.x backwards support.
441 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
443 * Changed all integer type names:
444 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
445 to avoid collisions with other libraries using same type names
448 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
450 * Added `prefer_ipv6' argument to the functions
451 silc_net_gethostbyname[_async]. If it is TRUE it will return
452 IPv6 address over IPv4. If FALSE IPv4 address is returned
453 even if IPv6 address was found. Affected files
454 lib/silcutil/silcnet.[ch].
456 * Added support silc_net_create_connection[_async] to fallback
457 to IPv4 address if IPv6 address could not be used (like if
458 it doesn't work on a specific system). Affected file in
459 lib/silcutil/unix/silcunixnet.c.
461 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
463 * Added silc_schedule_reinit function to do the enlarging
464 of the max tasks handling capabilities of the scheduler.
465 Affected files lib/silcutil/silcschedule.[ch].
467 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
469 * Added automatic extern "C" { ... } for C++ compilers so the
470 application does not need to define them. Affected file
471 includes/silcincludes.h.
473 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
474 old name went against naming convention. Applications now
475 include "silcclient.h" instead of "clientlibincludes.h".
476 Removed includes/clientlibincludes.h, it is redundant now.
478 * Renamed includes/version.h to silcversion.h.
480 * Added really preliminary support for OS/2 into the util
481 library. Only thread & mutex API is implemented, others
482 are still to be implemented. Created the lib/silcutil/os2/
483 directory. Created also file includes/silcos2.h.
485 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Added preliminary BeOS support into the util library.
488 Created lib/silcutil/beos/, and implemented all the needed
489 functions to support SILC on BeOS. Created also file
492 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
494 * Added proper initializations to silc's irssi code, so it's
495 now possible to load it as module. Affected files
496 irssi/src/silc/core/silc-core.c,
497 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
499 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
501 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
504 * Fixed the silcdoc document generator to correct generate
505 docs from all kinds of filenames. Affected files are
506 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
508 * ROBOdoc documented lib/silcutil/silcmemory.h.
509 Added also new function silc_memdup.
511 * Removed lib/silcutil/silcbufutil.h and moved those routines
512 to the lib/silcutil/silcbuffer.h.
514 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
516 * Added `user_count' to the SilcChannelEntry which now tells the
517 number of users on the channel. The user count is now saved
518 in normal server of global channels as well. Affected files
519 silcd/server.c, idlist.h, packet_receive.c and command.c.
521 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
522 include file utility functions.
524 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
525 instead of calling directly OS routines.
527 * Fixed NICK change printing in Irssi SILC Client. Fixed
528 KICKED notify printing in Irssi SILC Client. Affected file
529 irssi/src/silc/core/client_ops.c.

532 client_entry->channels hash table everytime nick is changed.
533 Affected file lib/silcclient/client.c.
535 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
537 * ROBOdoc documented the lib/silcske/silcske.h, and improved
538 the SKE interface a bit.
540 * Fixed padding problem in PKCS#1. The padding was not actually
541 random since the random number generator was used incorrectly.
542 This security bug affects only when encrypting with PKCS#1, and
543 it is not currently used at all in SILC. SILC only use signing
544 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
546 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
548 * Rewrote the notify handling in Irssi SILC client to not call

563 Optimized the use of SKE Mutual flag usage. Use it only
564 if connection authentication protocol is not based in public
567 Renamed all SilcServerConfigSection* to SilcServerConfig*
568 to have a bit shorter names.
570 Affected files silcd/serverconfig.[ch], server.[ch], and
573 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

607 Affected files irssi/src/silc/core/silc-core.c,
608 irssi/src/fe-text/silc.c.
610 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
612 * Added new configuration options and blocks:
613 keepalive_secs, reconnect_count, reconnect_interval,
614 reconnect_interval_max, reconnect_keep_trying and
615 require_reverser_lookup. Added ConnectionParam block, and
616 implemented the connection parameters when connecting as
617 initiator and when accepting connections as responder.
619 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
620 whether given configuration value has been given already.
622 Affected files silcd/serverconfig.[c], server.[c].
624 * Splitted the doc/example_silcd.conf.in. Separated the crypto
625 algorithm parts and created new file silcalgs.conf, that
626 is now included from the example_silcd.conf.in.
628 * Optimized the silc_server_connect_to_router_second to take
629 the connection configuration object from the SilcServerConnection
630 object instead of finding it during the connecting phase.
631 Added the configuration object to SilcServerConnection struct.
632 Affected files silcd/server_internal.h, server.c.
634 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

646 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
648 * Unified the serverconfig.[ch]'s helper function interface.
649 Affected file silcd/serverconfig.[ch].
651 * Removed doc/example_silc.conf.in since it is redundant.
652 The make install will now install irssi/silc.conf file.
654 * Added new Passphrase and Publickey authentication methods to
655 config file, allowing both public key and passphrase based
656 authentication to be set at the same time.
658 Added `prefer_passphrase_auth' setting in config file which
659 can be used to set to prefer passwd auth if both passwd and
660 public key is set. If not set, public key is preferred.
661 This has effect only when being initiator (responder will try
664 Added support for authentication with passphrase and public key
665 at the same time. The passphrase is tried first always since
666 it is faster to check.
668 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
670 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

709 correct client. Affected file lib/silcclient/client_notify.c.
711 * Make silc_rng_alloc fail if it cannot allocate the sha1
712 hash algorithm. Affected file lib/silccrypt/silcrng.c.
714 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
716 * Fixed the file transfer's key agreement payload to include
717 zero port also if the hostname is NULL because it could not
720 Call file transfer monitor callback now also if error occurs
721 during key agreement protocol.
723 Changed the silc_client_file_send interface to return the
724 SilcClientFileError instead of session id. The session ID
725 is returned into pointer provided as argument.
727 Check that the file exists locally before sending the
728 file transfer request at all.
730 Affected file lib/silcclient/client_ftp.c, silcapi.h.

741 SILC_LOG_WARNING to give out Warning and not Error. Affected
742 file lib/silcutil/silclog.c.
744 * Fixed the channel message payload decryption in the function
745 silc_channel_message_payload_decrypt to not modify the original
746 buffer before it is verified that the message decrypted
747 correctly. Otherwise, next time it is called with correct
748 channel key it won't encrypt since the payload is corrupted.
749 Affected file lib/silccore/silcchannel.c.
751 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

763 * Fixed a bug in hash table internal routine for traversing
764 the table with foreach callback. The current entry may
765 become invalid in the callback but it was referenced after
766 the callback returned.
768 Do not allow auto rehashing of hash table during the
769 silc_hash_table_foreach operation, for same reasons as it is
770 not allowed for SilcHashTableList. Affected files are
771 lib/silcutil/silchashtable.[ch].
773 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
775 * Defined DLLAPI into silcincludes.h and silcwin32.h for

779 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
781 * Fixed private message handling. It used some old code that
782 caused the client to crash. Affecte file is
783 lib/silcclient/client_prvmsg.c.
785 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
787 * Added function silc_client_add_channel,
788 silc_client_replace_channel_id, and removed functions
789 silc_client_new_channel_id and silc_idlist_get_channel_by_id
792 * Added cross reference of the joined channels to the
793 SilcClientEntry, and changed the SilcChannelEntry's
794 users list to SilcHashTable. The affected files are
795 lib/silcclient/idlist.[ch].
797 * Fixed a bug in hash table tarversing. While the hash table
798 is traversed with SilcHashTableList the table must not be
799 rehashed. It is now guaranteed that auto rehashable tables
800 are not rehashed while tarversing the list. Also defined that
801 silc_hash_table_rehash must not be called while tarversing
802 the table. Added function silc_hash_table_list_reset that must
803 be called after the tarversing is over. The affected files are
804 lib/silcutil/silchashtable.[ch].
806 * Changed all hash table traversing to call the new
807 silc_hash_table_list_reset in server and in client library.
809 * Added function silc_client_on_channel to return the
810 SilcChannelUser entry if the specified client entry is joined
811 on the specified channel. This is exported to application as
812 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
814 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Fixed founder regaining problem with JOIN command on normal
817 server. The notify for mode change must be sent always and
818 not only if !cmd->pending. Affected file silcd/command.c.
820 * Fixed the WHOWAS command's reply sending to support the
821 lists correctly. Affected file silcd/command.c.
823 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
825 * When sending JOIN command to router for processing the
826 sender's old command identifier was not saved back to the
827 sender's command context, fixed now. The affected file is
830 * Create the key in JOIN command of the router did not return
831 the channel key, added check for this. Affected file is
834 * Fixed a channel ID update bug in JOIN command reply. Do
835 not directly upgrade the ID but call the function
836 silc_idlist_replace_channel_id if the ID was changed.
837 Affected file silcd/command_reply.c.
839 * Fixed memory leaks from command calling if it would fail.
840 Affected file silcd/command.c.

852 * Removed TRQ from lib/trq, not needed anymore.
854 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
855 with server connections. Later this will be configurable
856 in config file after new config file is done. Affected file
859 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
861 * Fixed a crash in server related to channel announcements.
862 Affected file silcd/server.c.
864 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
866 * Fixed memory leaks in silc_server_create_new_channel*
867 functions. Affected file silcd/server.c.
869 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
870 which ID was changed. This way the router will send the
871 user list for the channel again, and server won't be in
872 desync in some rare circumstances. Affected file is
873 silcd/packet_receive.c.
875 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
877 * Check for NULL socket pointer in the function

887 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
889 * Added lib/silcclient/client_ops_example.h as an template
890 file for application programmers to quickly start using
891 the SilcClientOperation functions in their application.
892 Updated the lib/silcclient/README as well to tell about this
893 nice file made available.
895 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
897 * Call silc_server_remove_from_channels when removing client
898 entry when NO_SUCH_CLIENT_ID was received. Affected file
899 is silcd/command_reply.c.
901 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
903 * Added server & router operator statistics updating. Affected
904 file silcd/packet_receive.c and silcd/command.c.
906 * Fixed the SERVER_SIGNOFF notify handling on normal server
907 not to save the history information for clients. Same was
908 fixed earlier in remove_clients_by_server function, but not
909 here. Affected file silcd/packet_receive.c.
911 * Raised the default connection-retry count from 4 to 7 in
912 server. Affected file silcd/server.h.
914 * Cancel any possible reconnect timeouts when we start the
915 key exchange. Affected file silcd/server.c.
917 * Do not reconnect on connection failure when SCONNECT was
918 given. Affected files silcd/server.[ch].

922 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
924 * Fixed the NICK command to always give the unformatted
925 nickname to the one giving the NICK command. If unformatted
926 nickname is cached already it will be formatted and the
927 local entry will always get the unformatted nickname.
928 Affected file lib/silcclient/idlist.c.
930 * Fixed some double frees from client library commands.
931 Affected file is lib/silcclient/command.c.
933 * Fixed CUMODE command in server to assure that no one can
934 change founder's mode than the founder itself, there was a
935 little bug. Affected file silcd/command.c.
937 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
939 * Removed the SilcClientCommandDestructor from the client
940 libary, it is not needed anymore. Affected files are
941 lib/silcclient/silcapi.h, command[_reply].[ch],
942 client_notify, idlist.c.
944 * Fixed GETKEY command to first resolve client, and then
945 resolve the server only if the client was not found, instead
946 of resolving both at the same time. Affected file is
947 lib/silcclient/command.c.
949 * Added silc_client_start_key_exchange_cb and lookup the
950 remote hostname and IP address before starting the key
951 exchange with server. The affected file is
952 lib/silcclient/client.c.
954 * The server's public key is now saved using the IP address
955 of the server and not the servername for the filename.
956 The hostname public key filename is checked as an fall back
957 method if the IP address based filename is not found.
959 Fixed the GETKEY command to save the fetched server key
962 Print the remote server's hostname now when new key is
963 received during connection process. Affected file is
964 irssi/src/silc/core/client_ops.c.
966 * Return always our own public key to the client if it asks
967 for it with GETKEY command. Affected file silcd/command.c.
969 * Removed the use_auto_addr variable from default config
970 file since it was in wrong section. Affected file is
973 * Fixed TOPIC_CHANGE notification to not route it when it
974 was sent using silc_server_send_notify_to_channel function.
975 Affected file silcd/command.c.
977 * Fixed silc_server_send_notify_kicked to send the kicker's
978 Client ID also, it was missing. Affected files are
979 silcd/command.c, silcd/packet_send.[ch].
981 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
983 * Do not save client history information in SERVER_SIGNOFF.
984 Fixes the bug in normal server that it does not detect
985 the client becoming valid after the server becomes back
986 online. Affected file silcd/server_util.c.
988 * Added `sock_error' field into the SilcSocketConnection
989 context. When error occurs during socket operation (read
990 or write) the error is saved. Added also new function
991 silc_socket_get_error to return human readable socket error
992 message. Affected files are lib/silcutil/silcsockconn.[ch],
993 lib/silcutil/unix/silcunixsockconn.c, and
994 lib/silcutil/win32/silcwin32sockconn.c.
996 * The server now prints the socket error message in the
997 signoff for client. Affected file silcd/server.c.
999 * Fixed the `created' channel information sending from router
1000 to server in JOIN command. Checks now whether the channel
1001 really was created or not and set it according that.
1003 Fixed the JOIN command to use the client entry's current
1004 ID during the joining procedure instead of the one it sent
1005 in the command (it is checked though), since it can change
1006 between the packet processing and command processing, and
1007 would just case unnecessary pain in the client end. Affected
1008 file silcd/command.c.
1010 * Fixed a channel key payload sending to use correct channel
1011 ID when the server was forced to change the channel's ID by
1012 router. Router sent the key payload with the old Channel ID.
1013 Affected file silcd/packet_receive.c.
1015 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1017 * Call silc_server_save_channel_key only if the key payload
1018 was provided in the JOIN command's command reply. Affected
1019 file silcd/command_reply.c.
1021 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1023 * Fixed silc_mp_sizeinbase to return the value correctly with
1024 MPI. Affected file lib/silcmath/mp_mpi.c.
1026 * Fixed the stop_server signal to correctly stop the scheduler
1027 and gracefully stop the server when SIGTERM or SIGINT signals
1028 are received. Affected file silcd/silcd.c.
1030 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1032 * Simple handling of TERM and HUP signals. Also added some log
1033 flushing call around. Affected file is
1036 * Fixed small bugs in silclog.c. Now buffering output will take
1037 effect after 10 seconds since startup: This will ensure that
1038 no important startup messages are lost. Also output redirection
1039 will preserve original format ([Date] [Type] message).
1040 Affected file is lib/silcutil/silclog.c.
1042 * Added two options to the config file, in the logging section:
1043 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1044 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1046 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1048 * Do not print the warning about log files not being initialized
1049 more than once to avoid excess logging. Affected file is
1050 lib/silcutil/silclog.c.
1052 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1053 the SIM copying in make install in Makefile.am.pre.
1055 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1057 * Rewritten silclog APIs. Globally interesting changes follows:
1058 silc_log_set_files() changed to silc_log_set_file().
1059 silc_log_set_callbacks() changed to silc_log_set_callback().
1060 ROBOdoc documented silclog header file.
1061 SilcLogCb now returns bool to wether inihibit the default
1062 handler or not (to keep the old behaviour return always TRUE).
1063 The new APIs should also fix the problem of the
1064 silcd_error.log file that was written in the current directory.
1067 Log files streams will remain opened after silc_log_set_file()
1068 call, means less CPU usage notably on high traffic servers.
1069 File streams are now full buffered, and flushed to the disk
1070 every 5 minutes, lesses HD activity and CPU usage.
1071 Messages can be redirected, allowing admins to configure
1072 one single logfile for all server messages.
1073 the silc_log_quick global variable to activate fast-logging.
1074 Affected files lib/silcutil/silclog.[ch]
1076 * Changed some code to conform new silclog APIs. Affected
1077 files are doc/example_silcd.conf.in, silcd/server.c
1078 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1081 * Fixed a memory leak that could occur in some situations.
1082 Affected file silcd/serverconfig.c.
1084 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1086 * Added the silc_client_del_client to remove the client from
1087 all channels as well. Affected file lib/silcclient/idlist.c.
1089 * Fixed the client library to correctly remove the client
1090 from all channels when the client entry is being destroyed.
1091 Affected file lib/silcclient/client_notify.c, command.c.
1093 * Added auto-nicking support to the client library. If the
1094 applicatio now sets client->nickname it will be sent to the
1095 server after connecting by the library. This way for example
1096 SILCNICK (or IRCNICK) environment variables will have effect
1097 and always change the nickname automatically to whatever
1098 it is wanted. Affected file lib/silcclient/client.[ch].
1100 * Renamed silc_server_command_bad_chars to the
1101 silc_server_name_bad_chars and moved it to the
1102 silcd/server_util.[ch]. Added also new function
1103 silc_server_name_modify_bad to return nickname that
1104 includes bad characters as new nickname without those
1105 bad characters. This check and modify is now used in
1106 silc_server_new_client when the username is initially set
1107 as nickname, so it must be checked to be valid nickname.
1108 Affected file silcd/packet_receive.c.
1110 * The nickname length is now taken from the packet for real
1111 and not trusted to strlen() since it clearly can return
1112 wrong length for nickname including bad characters. This
1113 also applies to channel names. Affected file silcd/command.c.
1115 * Removed the lib/silcsilm/modules directory. Modules are now
1116 compiled into the lib/silcsim. Fixed the copying of the
1117 modules to follow symbolic links in Makefile.am.pre.
1119 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1121 * Fixed silc_string_regexify list creation. Fixes bugs with
1122 BAN and INVITE commands in server. The affected file is
1123 lib/silcutil/unix/silcunixutil.c.
1125 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Removed the command destructor entirely from the server's
1128 command and command reply routines. It is not needed, and
1129 its usage was buggy and caused crashes. Affected files are
1130 silcd/command[_reply].[ch].
1132 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Cancel protocol and NULL sock->protocol if timeout
1135 occurred during protocol. Affected file silcd/server.c.
1137 * Cancel protocol timeouts always before calling the final
1138 callback, to assure that after final callback is called
1139 no other state will be called for the protocol anymore.
1140 Affected file silcd/protocol.c.
1142 * Print error log if incoming connection configuration could
1143 not be found. Affected file silcd/server.c.
1145 * Fixed JOIN command to correctly save the founder mode
1146 to the client on normal SILC server, when the channel
1147 was created by the router. Affected file silcd/command.c.
1149 * Fixed LIST command (hopefully) to send correct reply
1150 packets. Affected file silcd/command.c.
1152 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1154 * The silc_packet_receive_process now returns FALSE if the
1155 read data was invalid packet, and TRUE if it was ok.
1157 The server now checks that if unauthenticated connection
1158 sends data and its processing fails the server will close
1159 the connection since it could be a malicious flooder.
1161 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1163 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1165 * Make sure the warning about error opening a log file is
1166 printed only once and not everytime it fails (produces
1167 too much useless log). Affected file lib/silcutil/silclog.c.
1169 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1171 * Made the silc_server_daemonise() function more readable.
1172 Affected file silcd/server.c.
1174 * Pid file is now optional, the user may comment it out from
1175 the config file. Removed define SILC_SERVER_PID_FILE, we
1176 don't need a default any longer. Affected file
1177 configure.in.pre, lib/Makefile.am.pre.
1179 * Make some use of the pid file. The server now dies at startup
1180 if it detects a valid pid file on his path. The server would
1181 die anyway in this circumstance, because of the bind() failure.
1182 Affected file silcd/silcd.c.
1184 * No longer compiling lib/dotconf.
1186 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Fixed JOIN command parsing not to crash. Affected file
1189 lib/silcclient/command.c.
1191 * Fied the NICK_CHANGE notify to add the new client entry
1192 even it is resolved. This removes an <[unknown]> nick
1193 thingy bug in the client. Affected file is
1194 lib/silcclient/client_notify.c.
1196 * Do not try to allocate 0 bytes (efence does not like it)
1197 in lib/silccore/silccomand.c when encoding payload.
1199 * Do not take IRCNICK as nickname in Irssi SILC client since
1200 it is not possible to set nickname before hand connecting
1201 the server (TODO has an entry about adding auto-nicking
1204 * Changed the silc_server_command_pending to check whether
1205 there already exists an pending entry with the specified
1206 command, command identifier and pending callback. This is
1207 to fix IDENTIFY and WHOIS related crashes that may register
1208 multiple pending commands with same identifier. Affected
1209 file silcd/command.c.
1211 * Fixed the server to reconnect to the router even if it
1212 was already reconnecting and EOF was received. This to
1213 fix a possibility that the server wouldn't ever try to
1214 auto-reconnect to the router. Affected file silcd/server.c.
1216 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Fixed the server's password authentication to use the
1219 length of the locally saved password, and not the one
1220 sent in the packet. Affected file silcd/protocol.c.
1222 * Fixed same password authentication problem in the
1223 Authentication Payload handling routines in
1224 lib/silccore/silcauth.c.
1226 * Yet another password authentication problem fixed with
1227 channel password handling in silcd/command.c.
1229 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1231 * If first character of string in silc_parse_userfqdn is '@'
1232 then do not parse it. Affected file is
1233 lib/silcutil/silcutil.c.
1235 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Fixed minor bug in IDENTIFY command reply sending, which
1238 caused various weird problems during JOIN when it was
1239 resolving names for users. Affected file silcd/command.c.
1241 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1243 * Fixed the IDENTIFY command reply sending to chech better valid
1244 clients. It was possible to send incomplete list of replies.
1245 Affected file silcd/command.c.
1247 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * Added silc_client_command[s]_[un]register functions now to
1250 dynamically register the commands in client library. Removed
1251 the static table of commands. This allows the client library
1252 to call commands without causing the application to know about
1253 what commands library has called.
1255 Removed the INFO command reply kludge to detect when the command
1256 was called by library. Now library use its own command reply
1257 function for INFO command.
1259 Added function silc_client_command_call to call a command.
1260 Application can use it to call command, not access the structure
1263 Now all commands that are sent by the client library (not
1264 explicitly sent by application) use own command reply functions.
1266 Affected files around lib/silcclient/ and in
1267 irssi/src/silc/core/.
1269 * Fixed the WHOIS command reply sending to chech better valid
1270 clients. It was possible to send incomplete list of replies.
1272 Fixed the WHOIS and IDENTIFY to send the request to router
1273 if normal server did not do it and did not find any results.
1275 Affected file silcd/command.c.
1277 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * Moved the internal data from SilcClient context into its
1280 own file, not accesible to application. Affected files
1281 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1282 and other files in client library.
1284 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Added doc/examples installation target in Makefile.am.pre.
1289 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1292 commands the found client entry will be removed from the
1293 cache, after notifying application about the error. Affected
1294 file lib/silcclient/command_reply.c.
1296 * Changed the /MSG to check for exact nickname user gave, and
1297 not let `nick' match `nick@host' if it is only one found. Now,
1298 user must type the exact nickname (like nick@host2) even if
1299 there are no more than one same nicks found. This is to avoid
1300 a possibility of sending nickname to wrong nickname since
1301 `nick' could match `nick@host'. Affected file is
1302 irssi/src/core/silc-servers.c.
1304 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1306 * Do not print "you are now server operator" or similar when
1307 giving /away command. Affected files are
1308 irssi/src/silc/core/client_ops.c, silc-servers.h.
1310 * Made the silc_server_command_pending_error_check to send
1311 the same command reply payload it received back to the
1312 original sender of the command. This way all arguments
1313 that was received by the server will be received by the
1314 client too. Affected file silcd/command.c.
1316 * Added the silc_idcache_add to return the created cache entry
1317 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1319 * Add global clients to expire if they are not on any channel.
1320 This is because normal server will never know if they signoff
1321 if they are not on any channel. The cache expiry will take
1322 case of these entries. This is done by normal servers only.
1323 The affected files are silcd/command_reply.c,
1324 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1326 * If server receives invalid ID notification for WHOIS or
1327 IDENTIFY and the ID exists in the lists, it is removed.
1328 Affected file silcd/command_reply.c.
1330 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1331 in client then client entry that it matches is searched and
1332 the nickname is printed on the screen for user. Affected
1333 file irssi/src/silc/core/client_ops.c.
1335 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Use cache entry expire time in the LIST command reply to
1338 purge old entries from the cache after the LIST command
1339 reply has been received. This way we don't have non-existent
1340 entries in the cache for too long. Affected file is
1341 silcd/command_reply.c.
1343 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * If we are normal server, and we've not resolved client info
1346 in WHOIS or IDENTIFY from router, and it is global client,
1347 we'll check whether it is on some channel. If it is not
1348 then we cannot be sure about its validity and will resolve it
1349 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1350 file silcd/command.c.
1352 * Search channel by name (if possible) rather than by ID
1353 in IDENTIFY command's command reply. Affected file is
1354 silcd/command_reply.c.
1356 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1359 Updated specs and implemented it. Affected file silcd/command.c,
1360 silcd/packet_send.c and silcd/packet_receive.c.
1362 * Implemented the <founder auth> payload handling in the JOIN
1363 command. If provided all conditions for channel joining
1364 except requirement to provide correct passphrase can be
1365 overrided by the channel founder. Updated the protocol specs.
1366 Affected file silcd/command.c.
1368 Added support for founder auth in JOIN command in client
1369 library. Fixed the parsing of the JOIN command now to support
1370 all options as they should be. The affected file is
1371 lib/silcclient/command.c.
1373 * Optimized the WHOIS and IDENTIFY commands to send the request
1374 to router only if it includes nicknames or other names. If
1375 they include only IDs then check the local cache first before
1376 routing. Affected file is silcd/command.c.
1378 * Added channels topic announcements. Affected file is
1379 silcd/packet_receive.c and silcd/server.c.
1381 * Fixed the silc_server_send_notify_topic_set to really destine
1382 the packet to channel. Affected file silcd/packet_send.c.
1384 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1385 library. Affected file lib/silcclient/client_notify.c.
1387 * Added UMODE announcements. Affected file silcd/server.c.
1389 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Memory leak fixes in:
1393 lib/silcutil/silcsockconn.c
1394 lib/silcske/silcske.c
1395 lib/silcske/groups.c
1397 lib/silccrypt/silcpkcs.c
1398 lib/silccore/silccommand.c
1399 lib/silccore/silcidcache.c
1404 * ROBOdoc documented the lib/silcske/groups.h file and a
1405 bit changed the interface for better.
1407 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1409 * Update the client entry context in the ID cache after
1410 nick change. Affected file lib/silcclient/command.c.
1411 Fixes the CUMODE command when regaining founder privileges,
1412 and a little WHOIS problem.
1414 * Fixed silc_net_gethostbyname to correctly call the
1415 inet_ntop. Affected file lib/silcutil/silcnet.c.
1417 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1419 * Added IPv6 support checking to the configure.in.pre, added
1420 also --enable-ipv6 option to override the check. Affected
1421 file configure.in.pre.
1423 * The silc_thread_create now calls the start function
1424 directly if threads support is not compiled in. Removes
1425 ugly #ifdef's from generic code. Affected files are
1426 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1428 * Added silc_net_gethostby[name/addr]_async to asynchronously
1429 resolve. Affected files are lib/silcutil/silcnet.[ch].
1431 * Added support for rendering IPv6 based server, client and
1432 channel IDs. Affected file lib/silcutil/silcutil.c.
1434 * Added support for creating IPv6 based server IDs. Affected
1435 file is silcd/serverid.c.
1437 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1439 * Added silc_net_gethostby[addr/name] into the
1440 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1441 routines. Added silc_net_is_ip[4/6]. Affected file is
1442 lib/silcutil/unix/silcunixnet.c. All routines that take
1443 address as argument now supports both IPv4 and IPv6 addresses.
1445 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1447 * Fixed LIST command reply sending in server. Affected file
1450 * Server now sends the kicker's client ID in the KICK notify
1451 to the kicked client. Affected file silcd/command.c.
1453 * The client library now parses the kickers client ID and
1454 UI displays it. Affected files lib/silcclient/client_notify.c
1455 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1457 * Made all payload parsing function prototypes consistent.
1458 They all take now const unsigned char * and uint32 pair as
1459 the payload data instead of SilcBuffer. Changes all around
1460 the source tree. Other unsigned char* -> const unsigned char*
1461 changes around the tree as well.
1463 * Optimized SFTP client and server packet sending not to
1464 allocate new buffer for each packet but to recycle the
1465 first allocated buffer. Affected files are
1466 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1468 * Optimized the SFTP client to use SilcList instead of
1469 SilcDList for requests, because it is faster. Affected file
1470 is lib/silcsftp/sftp_client.c.
1472 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1473 into lib/silccore/silcid.[ch].
1475 Renamed silcpayload.[ch] into silcargument.[ch].
1477 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * If client entry is deleted with active key agreement
1480 session, abort the session.
1482 The silc_client_abort_key_agreement now calls the completion
1483 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1485 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1488 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1490 * Don't use __restrict in older GCC's. Affected file is
1491 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1493 * silc_net_localhost now attempts to reverse lookup the
1494 IP/hostname. Affected file lib/silcutil/silcnet.c.
1496 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1497 command. It can be used to gain founder privileges at
1498 the same time when joining the channel.
1500 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1501 kicker's client ID as well. Updated protocol specs.
1503 Defined that the server must send SILC_COMMAND_IDENTIFY
1504 command reply with error status to client who sent
1505 private message with invalid client ID.
1507 Updated the protocol specification.
1509 * Added silc_server_send_command_reply to send any
1510 command reply. Affected file silcd/packet_send.[ch].
1512 * Added silc_id_payload_encode_data to encode ID payload
1513 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1515 * The server now send IDENTIFY command reply with error
1516 status if client ID in private message is invalid. Affected
1517 file silcd/packet_receive.c.
1519 * Save the server key file with server's IP address in
1520 the filename instead of hostname. The affected file is
1521 irssi/src/silc/core/client_ops.c.
1523 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1528 * Added libtool support for compiling shared objects in
1529 lib/silcsim. Affected file configure.in.pre and
1530 lib/silcsim/Makefile.am. Original patch by cras.
1532 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1534 * Pid file configuration, and server's config file fixes
1535 patch by toma. Updated CREDITS file.
1537 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1539 * Fixed silc_client_channel_message to not try to decrypt
1540 the message twice if it resolved the destination client
1541 information. This could cause of dropping one channel
1542 message. Affected file lib/silcclient/client_channel.c.
1544 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1546 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1547 lib/silcclient/client.c. This function is used when the SILC
1548 Client is run under some other scheduler, or event loop or
1549 main loop. On GUI applications, for example this may be
1550 desired to used to run the client under the GUI application's
1551 main loop. Typically the GUI application would register an
1552 idle task that calls this function multiple times in a second
1553 to quickly process the SILC specific data.
1555 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1557 * Fixed silc_server_drop() for dropping the supplementary
1558 groups as well, this could cause a security hole on some
1561 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1566 * Write PID file after dropping privileges. Added -F option
1567 to run server on foreground. A patch by debolaz.
1568 Affected files silcd/server.c, silcd/silcd.c.
1570 * Fixed MOTD to return the MOTD file server name. Affected
1571 file silcd/command.c.
1573 * Added INFO command reply handling to the Irssi SILC Client.
1574 Affected file irssi/src/silc/core/client_ops.c.
1576 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Fixed the silc_idcache_list_* routines to really support
1579 the dynamic list. Fixes a crash. Affected file is
1580 lib/silccore/silcidcache.c.
1582 * Fixed the LIST command reply to really call LIST command's
1583 pending callbacks. Affected file silcd/command_reply.c.
1585 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Update conn->local_entry->nickname after giving NICK
1588 command. Affected file lib/silcclient/command.c.
1590 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1592 * Added the [pid] option to the silcd configuration file
1594 Affected files: serverconfig.[ch] and silcd.c
1596 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Save fingerprint in WHOIS command reply in server.
1599 Affected file silcd/command_reply.c.
1601 * Fixed NICK commands pending callback registration.
1602 Affected file lib/silcclient/command.c.
1604 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Use ++server->cmd_ident when sending commands in server,
1607 instead of random number. Affected file silcd/command.c.
1609 * Fixed GETKEY command reply to call actually GETKEY pending
1610 command callbacks. Affected file silcd/command_reply.c.
1612 * A bit stricter check for nicknames. Check for same nickname
1613 in NICK command also. Affected file silcd/command.c.
1615 * Do not call INFO command everytime client ID changes, only
1616 during first connecting. Affected file lib/silcclient/client.c.
1618 * Set the new nickname only after successful command reply for
1619 NICK command is returned by server. Affected file
1620 lib/silcclient/command.c.
1622 * Remove nicknames from nicklist during server_signoff notify.
1623 Should fix /NAMES bit more. The affected file is
1624 irssi/src/silc/core/silc-channels.c.
1626 * Added `fingerprint' field to the SilcIDListData in the
1627 silcd/idlist.h to hold the fingerprint of the client's
1630 Send the fingerprint of the client's public key in WHOIS
1633 Affected files silcd/command.c, and silcd/idlist.[ch].
1635 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1636 create fingerprint from given data.
1638 * Show the fingerprint of the client's public key in WHOIS.
1639 Affected files irssi/src/module-formats.[ch] and
1640 irssi/src/silc/core/client_ops.c.
1642 * Format the multiple same nicknames also during JOIN and
1643 NICK_CHANGE notifys. Affected file is
1644 lib/silcclient/client_notify.c.
1646 * Do not print error on screen for invalid private message
1647 payload since it can come if someone is sending private
1648 messages with wrong key. Affected file
1649 lib/silccore/silcprivate.c.
1651 * Fixed multiple concurrent /PING crash. Affected file
1652 lib/silcclient/command.c.
1654 * Changed the wrong ID encoding. All IP addresses must be
1655 in MSB first order in encoded format. They were encoded
1656 wrong and was in LSB format. Affected files are
1657 silcd/serverid.c, lib/silcutil/silcutil.c.
1659 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1661 * Call the `connect' client operation through the scheduler
1662 in case of error. Affected file lib/silcclient/client.c.
1664 * Call the `failure' client operation even if the error
1665 occurred locally during a protocol. Affected file is
1666 lib/silcclient/protocol.c.
1668 * Added support of sending LIST command to router from normal
1669 server. This way normal server can get list of all channels
1670 in the network too. Fixed the channel list sending in the
1671 server too. Affected files are silcd/command.c, and
1672 silcd/command_reply.[ch].
1674 * Added silc_server_update_channels_by_server and
1675 silc_server_remove_channels_by_server. They are used during
1676 disconnection of primary router and in backup router protocol.
1677 Affected file silcd/server_util.[ch], silcd/server.c and
1678 silcd/server_backup.c.
1680 * Fixed channel adding to global list in IDENTIFY command
1681 reply in server. Affected file silcd/command_reply.c.
1683 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * If the incoming packet type is REKEY or REKEY_DONE process
1686 that packet always synchronously. Fixes yet another MAC
1687 failed error on slow (dialup) connections. Affected file
1688 lib/silcclient/client.c and silcd/server.c.
1690 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Call check_version SKE callback for initiator too. Affected
1693 file lib/silcske/silcske.c.
1695 * Implemented fix for security hole found in the SKE that was
1696 fixed in the specification few days back; the initiator's
1697 public key is now added to the HASH value computation.
1698 Added backwards support for the old way of doing it too, for
1699 old clients and old servers. Affected file is
1700 lib/silcske/silcske.c.
1702 * Enabled mutual authentication by default in SKE. If initiator
1703 is not providing mutual authentication the responder will
1704 force it. This will provide the proof of posession of the
1705 private key for responder. The affected files are
1706 lib/silcclient/protocol.c and silcd/protocol.c.
1708 * Do not cache anymore the server's public key during SKE.
1709 We do mutual authentication so the proof of posession of
1710 private key is done, and if the server is authenticated in
1711 conn auth protocol with public key we must have the public
1712 key already. Affected file silcd/protocol.c.
1714 * Added new global debug variable: silc_debug_hexdump. If
1715 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1716 file lib/silcutil/silclog.[ch].
1718 * Fixed compilation warning due to char * -> const char *.
1719 Affected files lib/silcutil/silcnet.h, and
1720 lib/silccore/silcauth.[ch].
1722 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Fixed CMODE command when new channel key was created. If
1725 the creation failed the old key was removed. Next time giving
1726 same command would crash the server since the old key was
1727 freed already. Affected file silcd/command.c.
1729 * Fixed the silc_server_announce_get_channels to not crash
1730 on reconnect. Affected file silcd/server.c.
1732 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1734 * Added silc_log_set_debug_string function to set a regex
1735 string to match for debug output. Only the function names,
1736 or filenames matching the given debug string is actually
1737 printed. This way it is possible to filter out those debug
1738 strings that user is not interested in.
1740 Fixed a bug in silc_string_regexify.
1742 Affected files lib/silcutil/silclog.[ch], and
1743 lib/silcutil/unix/silcunixutil.c.
1745 * Changed the -d options in both server and Irssi SILC client
1746 to take the debug string as argument. Affected files
1747 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1749 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Added silc_hash_babbleprint to create a Bubble Babble
1752 Encoded fingerprint. The encoding is developed by Antti
1753 Huima (draft-huima-babble-01.txt), and it creates human
1754 readable strings out of binary data. Affected file
1755 lib/silccrypt/silchash.[ch].
1757 * Print the babble print now in addition of fingerprint as well
1758 in Irssi SILC client. Affected files are
1759 irssi/src/fe-common/silc/module-formats.[ch],
1760 irssi/src/fe-common/silc/core/client_ops.c.
1762 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Fixed a security problem found in SKE. The initiator's
1765 public key too is now added to the HASH hash value creation
1766 which is signed by the responder to create the SIGN value.
1767 This will prevent anyone in the middle to lie to the responder
1768 about the initiator's public key. If this is done now, the
1769 man in the middle will get caught. Updated the protocol
1772 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Better installation directory handling. Configure module
1775 paths and other paths automatically to example_silc* files
1776 in doc/. A patch by toma.
1778 * Fixed compiler warning from MPI library, and from SILC RNG.
1781 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1782 It can be configured with ./configure. A patch by toma.
1784 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Find correct make to use in prepare-clean. A patch by
1787 toma. Affected file prepare-clean.
1789 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1791 * Added irssi variables use_auto_addr, auto_bind_ip,
1792 auto_bind_port and auto_public_ip.
1794 * Changed the interface for silc_client_send_key_agreement
1795 in lib/silcclient/silcapi.h
1799 irssi/src/silc/core/silc-core.c
1801 lib/silcclient/silcapi.h
1802 irssi/src/silc/core/silc-channels.c
1803 lib/silcclient/client_keyagr.c
1806 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Added silc_pkcs_public_key_compare to compare two
1809 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1811 * Check that the client who set the founder mode on the
1812 channel is the same client that is giving the founder
1813 mode to itself. It is done by comparing the saved public
1814 key (it is saved even in the authentication is passphrase).
1815 Affected file silcd/command.c.
1817 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Do not process packet for disconnected socket connection.
1820 Affected file lib/silccore/silcpacket.c.
1822 * Process the DISCONNECT packet through scheduler in the
1823 client library. Affected file lib/silcclient/client.c.
1825 * Fixed the silc_client_packet_parse to not to increase
1826 the packet sequence number if the conn->sock and the
1827 current socket connection is not same. This can happen
1828 for example during key agreement when the conn includes
1829 multiple socket connections (listeners). Affected file
1830 lib/silcclient/client.c.
1832 * The sender of the file transfer request now provides also
1833 the pointer (listener) for the key exchange protocol. If
1834 the listener cannot be created then it sends empty key
1835 agreement and lets the receiver provide the listener.
1837 Added `local_ip' and `local_port' arguments to the
1838 silc_client_file_send. If they are provided they are used,
1839 if not then it will attempt to find local IP address, if
1840 not found or bind fails then the remote client will provide
1843 Affected files are lib/silcclient/client_ftp.c and
1844 lib/silcclient/silcapi.h.
1846 * Extended the FILE SEND command to support defining the
1847 local IP and port for key exchange listener. They are
1848 optional. Affected file irssi/src/silc/core/silc-servers.c.
1850 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Defined to WHOIS command reply the sending of fingerprint
1853 of the client's public key (if the proof of posession of the
1854 corresponding private key is verified by the server).
1855 Updated to the protocol specification.
1857 * Added support of receiving the client's public key's
1858 fingerprint in command reply in client library. Affected
1859 file is lib/silcclient/command_reply.c, and
1860 lib/silcclient/idlist.[ch].
1862 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Do not send over 128 chars long nickname to the server
1865 in NICK command. Affected file lib/silcclient/command.c.
1867 * Do not send over 256 chars long channel names to the server
1868 in JOIN command. Affected file lib/silcclient/command.c.
1870 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Assure that silc_server_close_connection cannot be called
1873 twice for same socket context. Affected file is
1876 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Send error message to application if opening file for
1879 writing during file transfer fails. Affected file is
1880 lib/silcclient/client_ftp.c.
1882 Remove all file transfer sessions for a client that we're
1883 removing from ID cache.
1885 Affected file is lib/silcclient/client_ftp.c.
1887 * Fixed silc_net_addr2bin to return correct address. Affected
1888 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1890 * Fixed file transfer session removing on signoff notify.
1891 Affected file irssi/src/silc/core/silc-servers.c.
1893 * Added the SilcClientFileError to be returned in the monitor
1894 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1895 Affected file lib/silcclient/silcapi.h.
1897 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Fixed a crash in silc_client_ftp_free_sessions and
1900 silc_client_ftp_session_free_client. Affected file
1901 lib/silcclient/client_ftp.c.
1903 * Added `disabled' field in the SilcChannelEntry in the server
1904 to indicate if the server entry is disabled. Affected file

1914 * Fixed a crash in client resolving in client_prvmsg.c in
1915 client library. Affected file lib/silcclient/client_prvmsg.c.
1917 * Do not actually remove the client directly from ID cache
1918 during SERVER_SIGNOFF, but invalidate it. This way we
1919 preserve the WHOWAS info for the client. Affected file
1920 silcd/server_util.c.
1922 * Fixed SERVER_SIGNOFF notify handling in the server. The
1923 server is now able to process incoming SERVER_SIGNOFF notify
1924 for a server that it doesn't even know about. It will remove
1925 the clients provided in the notify. Affected file
1926 silcd/packet_receive.c.
1928 * Check for partial packet in data queue after every packet that
1929 was found from the queue. Return and wait for more data if
1930 there is partial data in queue. Affected file is
1931 lib/silccore/silcpacket.c.
1933 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Added SilcClietFileError enum to indicate error in
1936 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1937 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1938 Affected files lib/silcclient/silcapi.h and
1939 lib/silcclient/client_ftp.c.
1941 * Check that newsize in silc_buffer_realloc is larger than
1942 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1944 * Added better monitor of file transfers. It now monitors
1945 key agreement protocol during the file transfer too. Added
1946 error reporting too. Affected files
1947 irssi/src/silc/core/silc-servers.c,
1948 irssi/src/fe-common/silc/module-formats.[ch].
1950 * Wrote a help file for FILE command.
1952 * Added silc_rng_global_get_byte_fast to get not-so-secure
1953 random data as fast as possible. Random data is read from
1954 /dev/urandom if available and from the SILC RNG if not
1955 available. It is used in padding generation. Affected file
1956 lib/silccrypt/silcrng.[ch].
1958 * All packets in client library are now processed synchronously.
1959 Optimized packet processing a lot. Affected file
1960 lib/silcclient/client.c.
1962 * All server connection packets are processing synchronously
1963 now in server, to optimize packet processing. Affected file
1966 * Include files are installed now only in Toolkit distribution
1967 if make install is given. Affected files: all Makefile.am's.
1969 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Assure that silc_client_notify_by_server_resolve does not
1972 resolve the client information multiple times. If it cannot
1973 be found by the first it cannot be found at all. Affected
1974 file lib/silcclient/client_notify.c.
1976 * Fixed WHOWAS command reply calling. Affected file
1977 lib/silcclient/command_reply.c.
1979 * Removed all references to silc_idlist_get_client from the
1980 Irssi SILC client since that call is internal call used by
1981 the library. The Irssi SILC client will use now client
1982 retrieval functions found in silcapi.h.
1984 * Fixed a bug in resolving nickname info before sending
1985 private message. It used freed memory. Affected file
1986 irssi/src/silc/core/silc-servers.c.
1988 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Assure my_channels statistics cannot go negative in server.
1991 Affected files silcd/server.c, silcd/server_util.c.
1993 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2007 * Added silc_net_localip to return local host's IP address.
2008 Affected file lib/silcutil/silcnet.[ch].
2010 * If key exchange or rekey protocol is active for a connection
2011 parse all packets syncronously since there might be packets
2012 in packet queue that we are not able to process without first
2013 processing packets before them. Affected file silcd/server,
2014 lib/silcclient/client.c.
2016 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2017 whether library should continue processing the packet.
2018 Affected file lib/silccore/silcpacket.h.
2020 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2049 lib/silcutil/silcutil.[ch].
2051 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Resolve the client info when received private message or
2054 channel message for a client which nickname we don't know.
2055 Affected files lib/silcclient/client_prvmsg.c and

2064 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2065 is incomplete and is being resolved, it won't be resolved
2068 Make sure also that USERS command reply does not resolve
2069 twice information. Affected file is
2070 lib/silcclient/command_reply.c.
2072 Make sure that silc_client_get_clients_by_list does not
2073 resolve twice same information.
2075 * Check for valid client->id in the silc_server_free_client_data.
2076 Affected file silcd/server.c.
2078 * Fixed /GETKEY nick@server not to crash if the server entry
2079 is not found. Affected file lib/silcclient/command.c.
2081 * Fixed the silc_server_check_cmode_rights to check the
2082 requested modes correctly. Affected file silcd/command.c.
2084 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Better checks for non-printable chars in nick added.
2087 Affected file silcd/command.c.
2089 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Call the silc_server_udpate_servers_by_server in the
2092 primary router that comes back online in the backup resuming
2093 protocol. Otherwise it routes packets wrong. Affected file
2094 silcd/server_util.[ch], silcd/server_backup.c.
2096 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2099 lib/silcutil/silcbuffmt.[ch].
2101 * Redefined the SILC packet header to include the padding
2102 length. Affected file lib/silccore/silcpacket.[ch].
2104 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2105 length for maximum padding up to 128 bytes). Affected
2106 file lib/silccore/silcpacket.h.
2108 * Removed all backwards support for old 0.5.x MAC thingies.
2109 The SILC packet header change makes it impossible to be
2110 backwards compatible.
2112 * Send the ENDING packet with timeout in the backup resuming
2113 protocol. This is to assure that all routers has connected
2114 to the primary router. Affected file silcd/server_backup.c.
2116 * Changed the RNG to take the first IV from random data. It
2117 used to take it from zero actually. Changed the RNG also
2118 to use /dev/urandom during session. /dev/random is used
2119 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2121 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Changed the SILC packet header to have the first two bytes
2124 (the packet length) encrypted. Affected files aroung the
2125 code tree, lib/silccore/silcpacket.[ch]. Removed the
2126 SilcPacketCheckDecrypt callback. It is not needed anymore
2127 since the silc_packet_receive_process will determine now
2128 whether the packet is normal or special.
2130 * Implemented the unidirectional MAC keys. Affected files
2131 lib/silcske/silcske.c, silcd/protocol.c and
2132 lib/silcclient/protocol.c.
2134 * Implemented the packet sequence number to the MAC computation.

2141 * Allow backup router to announce servers. All servers
2142 announced by backup router are added to the global list
2143 automatically. Update hte server's socket to our primary
2144 router also when backup router announces a server.
2145 Affected file silcd/packet_receive.c.
2147 * Do not update the client->router in the function
2148 silc_server_udpate_clients_by_server if the client is on
2149 global list. We might fail to find any specific server
2150 for locally connected clients and local cell clients. They
2151 should still use the `from' and not `to' as client->router.
2152 This fixes backup router resuming protocol. Affected file
2153 silcd/server_util.c.
2155 * Decrease channel statistics count only if the channel
2156 deletion worked. Affected files are silcd/server.c and
2157 silcd/server_util.c.
2159 * Added silc_server_update_servers_by_server to update origin
2160 of all server entries. Used during backup router protocol.
2161 Affected files silcd/server_util.[ch], silcd/server.c. and
2162 silcd/backup_router.c.
2164 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2165 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2166 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2167 lib/silccrypt/silchmac.c.
2169 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Assure that router cannot reroute the same channel message
2172 to the sender. Affected file silcd/packet_receive.c.
2174 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Made better checks that the channel message is not sent
2177 to the router it came from. Affected file is
2178 silcd/packet_send.c. Fixed memory leak too.
2180 * Announce informations for incoming router connection, but
2181 only after checking if it is replaced by backup router.
2182 Affected file silcd/packet_receive.c.
2184 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2186 * Fixed the backup resuming protocol to work in multiple
2187 router environment. Affected file silcd/server_backup.c.
2189 * Route packet only to one router in the function
2190 silc_server_packet_send_to_channel. Affected file is
2191 silcd/packet_send.c.
2193 * Fixed silc_server_send_notify_dest to set the broadcast
2194 flag. Fixed the silc_server_send_notify_topic to actually
2195 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2196 Affected file silcd/packet_send.c.
2198 * Changed the SFTP Filesystem interface. Changed the
2199 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2200 the filesystem operation function. The SilcSFTPFilesystem
2201 is now a context that is allocated by all filesystem allocation
2202 functions and it already includes the operations structure
2203 and filesystem specific context. It is given as argument
2204 now to the silc_sftp_server_start. This made the interface
2205 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2206 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2208 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Changed the backup router adding and getting interfaces
2211 in the server. The router that will be replaced by the
2212 specified backup router is now sent as argument. Affected
2213 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2216 * Added silc_net_addr2bin_ne to return the binary form of
2217 the IP address in network byte order. Affected files
2218 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2220 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2222 * Check for existing server ID in silc_server_new_server
2223 and in silc_server_connect_to_router_final and remove the
2224 old entry if it exists. Affected file silcd/packet_receive.c,
2227 * Send the channel message always to only one router, either
2228 in upstream or downstream. Affected file is
2229 silcd/packet_send.c.
2231 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Wrote the definition of the backup resuming protocol to the
2234 protocol specification.
2236 * Removed one redundant channel key generation from normal
2237 server during joining procedure. Removed one redundant
2238 channel key sending from server to router during joining
2239 procedure. Affected file silcd/command.c.
2241 * Made minor bugfixes to the backup router resuming protocol.
2242 Affected file silcd/server_backup.c, server.c.
2244 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Added --disable-asm configuration option. Affected files
2247 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2250 * Implemented the backup resuming protocol that is used to
2251 resume the primary router position in the cell after the
2252 primary router comes back online. Affected files
2253 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2254 and silcd/server_util.[ch].
2256 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Sleep two (2) seconds after sending QUIT command to server.
2259 Affected file lib/silcclient/command.c.
2261 * Assure that if outgoing data buffer is pending do not force
2262 send any data. Affected file silcd/packet_send.c.
2264 * Assure that if outgoing data buffer is pending do not force
2265 send any data. Affected file lib/silcclient/client.c.
2267 * Implemented the backup router support when the primary router
2268 goes down. The servers and routers can now use the backup
2269 router as new primary router without loosing connectivity.
2271 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2274 in the server to indicate disabled entry. All data read
2275 from the connection will be ignored and no data is sent
2276 for entry that is disabled. Affected files are
2277 silcd/idlist.h, silcd/server.c.
2279 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Created SFTP client and server test programs in the
2282 lib/silcsftp/tests directory.
2284 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2286 * Implemented memory filesystem (virtual filesystem) for
2287 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2290 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Implemented the SFTP (SSH File Transfer Protocol) to the
2293 lib/silcsftp. It includes SFTP client and SFTP server
2296 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Moved lib/silccore/silcprotocol.[ch] to the
2299 lib/silcutil library.
2301 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2302 take variable argument list pointer as argument. Affected
2303 file lib/silcutil/silcbuffmt.[ch].
2305 * Added silc_buffer_set function that is used to set data
2306 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2307 Affected file lib/silcutil/silcbuffer.h.
2309 * Changed various routines in the core library to use the new
2310 silc_buffer_set instead of allocating new buffer only for
2313 * Added 64-bit value formatting and unformatting support to the
2314 silc_buffer_[un]format routines. Affected file is
2315 lib/silcutil/silcbuffmt.[ch].
2317 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2318 to includes/bitmove.h.
2320 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Fixed channel user mode saving in client library. Affected
2323 file lib/silcclient/command[_reply].c.
2325 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Defined the file transfer to the SILC Protocol. Added
2328 new packet type SILC_PACKET_FTP and defined File Transfer
2329 Payload. The mandatory file transfer protocol is SFTP
2330 (SSH File Transfer Protocol). Affected file in addition
2331 of the internet draft is lib/silccore/silcpacket.h.
2333 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2334 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2335 is used as part of backup router protocol when the primary
2336 router of the cell is back online and wishes to resume
2337 the position as primary router.
2339 * Redefined the MAC generation keys in the protocol. The
2340 same key is not used anymore in both direction. Both
2341 direction will now use different keys for sending and
2342 receiving. This fixes a potential security flaw. This
2343 change causes incompatibilities in the protocol.
2345 * Redefined also the MAC computation from the packet.
2346 An packet sequence number is now added to the MAC
2347 computation. This prevents possible replay attacks against
2348 the protocol. This change too causes incompatibilities
2351 Added `sequence' field to the SilcPacketContext to hold
2352 the current sequence number for the packet.
2354 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Added `created' field to the SilcIDListData in the file
2357 silcd/idlist.h to indicate the time when the entry was
2360 * Added `created' field to the SilcChannelEntry too. Affected
2361 file silcd/idlist.h.
2363 * Added `creation_time' aguments to all the announcement functions
2364 in the server. If it is provided then only the entries that
2365 was created after the provided time frame are actually
2366 announced. Affected file silcd/server.[ch].
2368 * The protocol says that the Channel ID's IP address must be
2369 based on the router's IP address. Added check for this in
2370 the silc_server_new_channel when processing incoming New Channel
2371 Payload. Affected file silcd/packet_receive.c.
2373 * Print out the correct version with --version in SILC client.
2374 Affected file irssi/src/silc/core/silc-core.c.
2376 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Fixed WHOWAS command to check for completnes of the client
2379 entry always, not just when the command is coming from client.
2380 Affected file silcd/command.c.
2382 * Added new function silc_server_packet_queue_purge to purge the
2383 outgoing data queue to the network. After the function returns
2384 it is guaranteed that the outgoing packet queue is empty.
2385 Affected file silcd/packet_send.[ch].
2387 * Purge the outgoing packet queue in the rekey protocol's final
2388 callback to assure that all rekey packets go to the network
2389 before quitting the protocol. Affected file silcd/server.c.
2391 * Added silc_client_packet_queue_parse as similar function as
2392 in server to the client library. The affected file is
2393 lib/silcclient/client.c.
2395 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2397 * Splitted silcd/server.c and created silcd/server_util.[ch]
2398 for utility functions.
2400 * Added new socket flag SILC_SF_DISABLED to indicate that the
2401 connection is open but nothing can be sent to or received from
2402 the connection. Affected file lib/silcutil/silsockconn.[ch].
2403 The checking for disabled socket is checked in the low level
2404 silc_socket_write and silc_socket_read functions.
2406 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Allow only nicknames and channel names that fits into the
2409 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2411 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * When processing JOIN command reply in server check that if
2414 the channel exists in our global list we'll move it the local
2415 list. Affected file silcd/command_reply.c.
2417 * Fixed the check whether client is joined on the channel already
2418 in JOIN command. Affected file lib/silcclient/command.c.
2420 * Fixed the JOIN command reply to check whether the channel
2421 already exists. Affected file lib/silcclient/command_reply.c.
2423 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Added silc_ske_status_string to map the SKE error numbers
2426 to readable strings. The affected files are
2427 lib/silcske/silcske[_status].[ch].
2429 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Do not show the private channels on the WHOIS channel list
2432 as it is not allowed by the protocol. The affected file is
2435 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Assure that the packet length digged from the actual packet
2438 is something sensible in the silc_packet_decrypt_rest_special
2439 in lib/silccrypt/silcpacket.c.
2441 * Free and NULL the allocated pointer in silc_hmac_alloc if
2442 the HMAC allocation fails. The affected file is
2443 lib/silccrypt/silchmac.c.
2445 * Print the selected security properties to the log files in
2446 the server. Affected file silcd/protocol.c.
2448 * Add SKE's reference counter even if calling the completion
2449 callback manually. Otherwise it goes negative, although it
2450 does not cause any problems. The affected file is
2451 lib/silcske/silcske.c.
2453 * Remove the client entry with short timeout after giving the
2454 KILL command. Affected file lib/silcclient/command.c.
2456 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2457 case all found clients are already disconnected (WHOWAS would
2458 found them) in the server. Affected file silcd/command.c.
2460 * Update the last_receive (time of last data received) to be
2461 updated only when received private or channel message so that
2462 the idle time showed in WHOIS makes more sense.
2464 * Added boolean field `valid' in to the SilcClientEntry in the
2465 client library to indicate whether the entry is valid or not.
2466 This fixes the nickname change bug on channel when changing
2467 the nickname to be same than the old (like nick to Nick) the
2468 nickname formatter doesn't set the new nick anymore to Nick@host.
2469 Affected file lib/silcclient/idlist.[ch].
2471 * Now actually fixed the nickname changing on disconnection.
2472 Added new function silc_change_nick to the Irssi SILC Client.
2473 Affected file irssi/src/silc/core/client_ops.c,
2474 irssi/src/silc/core/silc-nicklist.[ch].
2476 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Check that the public key exists in the GETKEY command before
2479 trying to encode it. Affected file silcd/command.c.
2481 * Print some notifications on received public keys with GETKEY
2482 command in the Irssi SILC Client. Affected files are
2483 irssi/src/fe-common/silc/module-formats.[ch],
2484 irssi/src/silc/core/client_ops.c.
2486 * Use IDENTIFY command to resolve the server information in the
2487 GETKEY command instead of INFO command. Affected file
2488 lib/silcclient/command.c.
2490 * All command reply functions in the client library now calls
2491 the pending command reply callbacks even if an error has
2492 occurred. The server has done this a long time and now it was
2493 time to move the client library to this as well. Now all
2494 errors can be delivered back to the pending command reply
2495 callbacks if necessary. Affected files are
2496 lib/silcclient/command[_reply].[ch].
2498 * Change the nickname on disconnection back to the username
2499 because in reconnect the server will enforce it to it anyway.
2500 Affected file irssi/src/silc/core/silc-servers.c.
2502 * Fixed a config file parsing bug in the Irssi SILC client.
2503 Affected file irssi/src/silc/core/clientconfig.c.
2505 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2507 * When printing the channel mode on JOIN, verify that the
2508 channel key and channel's HMAC are valid. Affected file
2509 irssi/src/silc/core/client_ops.c.
2511 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2514 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2515 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2517 * Removed channel key rekey task deleting from the function
2518 silc_server_save_channel_key. Affected file silcd/server.c.
2519 Added explicit timeout task context instead that is used to
2520 delete the task if we are registering a new task before the
2521 new task has elapsed.
2523 * When channel key rekey occurs the client library now saves
2524 the old channel key for a short period of time (10 seconds) and
2525 is able to use it in case some is still sending channel
2526 messages encrypted with the old key after the rekey. Affected
2527 file lib/silcclient/[idlist.h|client_channel.c].
2529 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Added check to the silc_server_new_id_real to not accept
2532 new ID if it is the sender's own ID. Affected file is
2533 silcd/packet_receive.c.
2535 * Assure that we do not announce ourself or the one we've
2536 sending our announcements when we're router and are announcing
2537 servers to our primary router. Affected file silcd/server.c.
2539 * Fixed silc_server_command_identify_check_client to assemble
2540 correct WHOIS packet. It send corrupted WHOIS packet and
2541 caused problem with router to router connections. Affected
2542 file silcd/command.c.
2544 Fixed also silc_server_command_whois_check the same way
2545 as for the IDENTIFY command.
2547 * Added new SilcIDListStatus to the server in the SilcIDListData
2548 structure. The status now includes the current status of
2549 the entry (like registered, resolved etc.). Affected file
2550 silcd/idlist.[ch]. Defined a bunch of different status types
2551 as well. This replaced the old boolean registered field as well.
2553 Added resolve_cmd_ident field to the SilcClientEntry structure
2554 too so that if the entry is for example being resolved so
2555 another command may attach to the same pending command reply
2556 without requiring to resolve the same entry again. This concept
2557 should optimize the WHOIS and the IDENTIFY resolving under
2558 heavy load by taking away unnecessary resolving for entries
2559 that are being resolved already.
2561 Added support for adding multiple pending commands for one
2562 command idenfier. Affected file silcd/command[_reply].[ch].
2564 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2565 before deleting the data. Otherwise the hash table will have
2566 freed data in comparison functions. Affected file is
2567 silcd/command_reply.c.
2569 * Fixed silc_idlist_replace_client_id to add the new entry to
2570 the cache with NULL nickname. Otherwise there will be invalid
2571 memory as the nickname after the nickname is freed. Affected
2572 file silcd/packet_receive.c.
2574 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2575 saved into wrong slots because the previous number of entries
2576 was not taken into account. Affected file silcd/idlist.c.
2577 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2579 * If we are router and we receive JOIN notify to a channel that
2580 does not have any users then notified client is marked as the
2581 channel founder, as it is it. The affected file is
2582 silcd/packet_receive.c
2584 * Added to the extended hash table API's table_del_*ext functions
2585 the destructor as argument too, so that the caller can decide
2586 which destructor to use or whether to use destructor at all.
2587 Affected file lib/silcutil/silchashtable.[ch].
2589 * Fixed ID Cache purging. It actually deleted the entries from
2590 the hash table after the data was freed. The hash table ended
2591 up comparing freed memory. The affected file is
2592 lib/silccore/silcidcache.c.
2594 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Fixed Irssi SILC client's KILL command's HELP syntax.
2598 * The USERS command now resolves the detailed user information
2599 if the userinfo field is missing. Affected file is
2600 lib/silcclient/command_reply.c.
2602 * Do not print error in silc_file_read if the read file does
2603 not exist. Just silently return NULL. Affected file is
2604 lib/silcutil/silcutil.c.
2606 * Fixed the silc_log_output to not wine about NULL filename
2607 and to not create some bogus " " filename. Affected file is
2608 lib/silcutil/silclog.c.
2610 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Fixed various printing bugs on the user interface in the
2613 Irssi SILC Client. Minor changes that were forgotten from
2616 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2618 * Fixed the configure.in.pre and the compilation and distribution
2619 environment to support the new autoconf 2.52. That version is
2620 now required to compile the CVS trunk.
2622 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2625 to generally parse user@fqdn format strings. Affected file
2626 lib/silcutil/silcutil.c.
2628 * Added nickname_format and nickname_force_format fields to the
2629 SilcClientParams structure. The first one defines the format
2630 for the nicknames that the library will enforce if the receives
2631 multiple same nicknames. The second one is boolean value and
2632 can be used to force the library to always enforce the format
2633 to the nicknames regardles whether there are multiple nicknames
2634 or not. This configurable formatting was employed to flexibly
2635 support accessing multiple nicknames from the user interface.
2636 The userinterface can now set the nicknames to what ever format
2637 they prefer. Affected file lib/silcclient/silcapi.h.
2639 Added function silc_client_nickname_format to the file
2640 lib/silcclient/idlist.c. It performs the nickname formatting.
2642 Added new field `hostname´ to the SilcClientEntry context.
2643 It holds the hostname of the client. Affected file is
2644 lib/silcclient/idlist.h.
2646 * Irssi SILC Client sets the nicknames in nick@hostn format.
2647 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2648 irssi/src/silc/core/silc-core.c.
2650 The WHOIS printing now also shows both the real nickname and
2651 the formatted nickname so that user knows how to access the
2652 user if there are multiple same nicknames cached. Affected
2653 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2654 printing formatting too to take the hostname now as a separate
2655 argument. The Affected file is
2656 irssi/src/fe-common/silc/modules-formats.[ch].
2658 * Changed the silc_client_get_clients_local to accept the formatted
2659 nickname as argument. It accepts the real nickname too but the
2660 formatted nickname can be used to find the true entry from
2661 multiple entries. Affected file lib/silcclient/silcapi.h and
2662 lib/silcclient/idlist.c.
2664 * Added nickname_format_parse field to the SilcClientParams.
2665 It is a callback function provided by the application to parse
2666 the nickname out of the formatted nickname string. The library
2667 calls it to get the nickname from the formatted string. Since
2668 the application generally knows better the format of the nickname
2669 string it parses it instead of the library, even though library
2670 encodes the formatted string. If the callback function is not
2671 provided then the library will use the string as is. The
2672 affected file is lib/silcclient/silcapi.h.
2674 * All the nickname strings passed to the client library in
2675 commands are now expected to be formatted nickname strings.
2676 If the command does not support the formatted nickname string
2677 it will assume that the sent string is the actual nickname.
2678 Affected file lib/silcclient/command.c.
2680 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Added public key authentication support to OPER and SILCOPER
2683 commands in the client library. Affected file is
2684 lib/silcclient/command.c.
2686 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Changed the get_auth_methdod client operation to be asynchronous.
2689 It can be async if the application resolves the authentication
2690 method from the server during the negotiation. Added new
2691 SilcGetAuthMeth completion callback that the application will
2692 call after resolving the authentication method.
2694 Added function silc_client_request_authentication_method that
2695 the application can use to resolve the authentication method
2696 from the server. Added also SilcConnectionAuthRequest callback
2697 that the library will call after the server has replied. The
2698 application can call this function if it does not know the
2699 current authentication method.
2701 Affected files are lib/silcclient/client.c and
2702 lib/silcclient/silcapi.h.
2704 * The Irssi SILC client now automatically resolves the authentication
2705 method incase any configuration information is not present (and
2706 currently there never is). The affected file is
2707 irssi/src/silc/core/client_ops.c.
2709 * Fixed public key authentication from the client library.
2710 Affected file lib/silcclient/protocol.c. Changed also the
2711 protocol specification about the public key authentication in
2712 the connection authentication protocol. The actual data to be
2713 signed is now computed with a hash function before signing.
2715 * Fixed the public key authentication from the server as well.
2716 Affected file silcd/protocol.c.
2718 * Removed the mlock()'s from the memory allocation routines.
2719 Affected file lib/silcutil/silcmemory.c. The ./configure does
2720 not check anymore for the mlock(). Affected file is
2723 * Fixed USERS command in server to allow the execution of the
2724 command for private and secret channels if the client sending
2725 the command is on the channel. Affected file silcd/command.c.
2727 * Fixed silc_client_get_clients_local to return the clients
2728 count correctly. It could return wrong value. Affected file
2729 lib/silcclient/idlist.c.
2731 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2734 types. The assembler optimizations seemed not to like 64-bit
2735 data types. The assmebler optimizations thus are now enabled
2736 also for BSD systems as opposed to only enable them for Linux.
2738 * Do not check for threads at all on BSD systems. Affected
2739 file configure.in.pre.
2741 * Removed -n and -h options from the Irssi SILC Client since
2742 they are not used in silc.
2744 * Fixed the prime generation to assure that the first digit
2745 of the generated random number is not zero since our conversion
2746 routines does not like number strings that starts with zero
2747 digit. If zero digit is seen the random number is regenerated.
2748 This caused some corrupted RSA keys when the zero first digit
2749 was met. Affected file lib/silcmath/silcprimegen.c.
2751 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Fixed WIN32 configuration in the ./configure script.
2754 Fixed to include xti.h on environments that has it.
2755 Patches by Carsten Ilchmann and andrew.
2757 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2759 * Changed the silc_id_create_client_id to be collision
2760 resistant. It is now assured that there cannot be created
2761 two same client ID's. I suspect that some weird bugs in
2762 the server were actually caused by duplicate Client IDs.
2763 Affected file silcd/serverid.[ch]. A router receiving
2764 new ID now also assures and informs the sending server
2765 if the ID caused collision.
2767 * Changed the silc_id_create_channel_id to also assure that
2768 there are no collisions.
2770 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Statement about ignoring the Mutual Authentication flag when
2773 performing rekey with PFS was a bit misleading. It is ignored
2774 if it was set in the initial negotiation, it cannot be even
2775 set in the rekey. Fixed in the ke-auth draft. Started the
2776 new versions of the protocol drafts in the doc/.
2778 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Fixed a bug in silc_client_command_identify_save when saving
2781 new channel information. The channel name was no duplicated
2782 and caused crash on exit. Affected file is
2783 lib/silcclient/command_reply.c.
2785 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Fixed the getkey command handling in the server. Send just
2788 empty OK reply to the sender if the key could not be fetched
2789 (but everything else was ok, like the key just was not available).
2790 Changed the public key parameter to optional in the protocol
2791 specs so that empty OK reply can be sent. Affected file
2794 Added a message to Irssi SILC client to tell to user if the
2795 server did not return a public key.
2797 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Fixed a channel key regeneration bug. It registered new
2800 timeout tasks exponentially until all system resources were
2801 used. Affected file silcd/server.c.
2803 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Added the SILC Document generator to the scripts/silcdoc.
2806 It can be used to generate the Toolkit Reference Manual out
2807 of the source tree. Internally it will also use the RoboDoc
2808 generator now imported in util/robodoc.
2810 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Added couple of return's in rekey protocol if error orccurred
2813 during the protocol. The execution must be terminated.
2814 Affected file silcd/protocol.c. Also, terminate the protocol
2815 always with timeout.
2817 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * The client's Client ID was created initally from the wrong
2820 nickname (it could have been in format nick@host) in the
2821 silc_server_new_client. Affected file silcd/packet_receive.c
2823 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2825 * Added some SILC_LOG_ERROR's to various error conditions
2826 if client could not be added to ID cache. Affected files
2827 silcd/packet_receive.c and silcd/server.c.
2829 * When client's sock->user_data is freed, NULL also the
2830 client->router and client->connection pointers. Added check
2831 for these pointers being NULL to various places around the
2832 code. Affected file silcd/server.c.
2834 * Added client->data.registered == TRUE checks to various
2835 places around the code to assure that unregistered client's
2836 are not handled when it is not allowed. Affected file
2839 * Added `bool registered' fields to all
2840 silc_idlist_[server|client]_get_* routines to indicate whether
2841 the fetched client needs to be registered or not. Affected
2842 file silcd/idlist.[ch].
2844 * Add your own entry as registered to the ID cache in the
2845 server. Affected file server.c.
2847 * Fixed a bug in silc_server_new_server. The SilcServer was
2848 set as the new server's context instead of SilcServerEntry.
2849 This naturally caused some weird bugs.
2851 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Do not delete the channel rekey task when adding it
2854 for in silc_server_create_channel_key.
2856 * Changed the silc_server_create_channel_key to return
2857 TRUE or FALSE to indicate the success of the channel key
2860 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Fixed MSVC++ project files and added missing files to
2863 Makefiles under win32/.
2865 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Do not add TCP_NODELAY flag if the operating system
2868 does not have it defined. Affected files are
2869 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2871 * Fixed buffer overflow from Irssi SILC Client. Affected
2872 file irssi/src/fe-common/core/themes.c.
2874 * Fixed double free in client library in the file
2875 lib/silcclient/client.c when disconnecting from server.
2877 * Applied double free patch from cras to Irssi SILC client.
2878 Affected files irssi/src/core/[modules/expandos].c
2880 * Fixed the disconnection handling to Irssi SILC Client.
2881 The application must call silc_client_close_connection
2882 in ops->connect client operation in case of failure of
2883 the connection. Affected file is
2884 irssi/src/silc/core/client_ops.c.
2886 * Do not set sock->protocol to NULL in the function
2887 silc_client_close_connection after executing the protocol's
2888 final callback since the sock might not be valid anymore.
2889 Affected file lib/silcclient/client.c.
2891 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Do not enable SILC_THREADS if the linking with libpthread
2894 did not happen. Affected file configure.in.pre.
2896 * Added notion to protocol specification that server must
2897 verify the sent authentication payload with CMODE when
2898 setting the channel founder key. Implemented it to the
2899 server. Affected file silcd/command.c.
2901 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Added _EXTRA_DIST SILC distribution variable to the
2904 distributions file. It is used to conditionally add extra
2905 files or directories to the specific distribution. Affected
2906 files ./prepare, Makefile.am.pre and distributions.
2908 Removed the `_' from the start of the distribution names.
2911 * Added README.WIN32 for instructions to compile the Toolkit
2914 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Fixed a double free in disconnection in the server. Affected
2917 file is silcd/server.c.
2919 * Fixed the lib/silcske/groups.c to work now also with GMP
2920 MP library. The string conversion did not work when using
2921 specific base and the base is indicated in the string as well.
2923 * Created win32/ directory which now includes MSVC++ specific
2924 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2925 It will appear only in the toolkit distribution
2927 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Changed the key material distribution function in case when
2930 the hash output is too short. The data is now concatenated
2931 a bit differently than it used to. Made the change to the
2932 SKE protocol specification.
2934 * Added better GMP detection to configure.in.pre. A patch
2937 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Fixed a minor bug in SKE that might cause some problem on
2940 some platforms. Affected file lib/silcske/silcske.c.
2942 * Added the cookie checking for initiator in the SKE. It checks
2943 that the responder returns the sent cookie unmodified. The
2944 affected file is lib/silcske/silcske.c. Added new SKE
2945 error type INVALID_COOKIE that can be sent during the
2946 negotiation. Fixed some memory leaks as well.
2948 * Added the "invalid cookie" error message to Irssi SILC client's
2951 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Added `task_max' field to the SilcClientParams to indicate
2954 the maximum tasks the scheduler can handle. If set to zero,
2955 default values are used. Affected file lib/silcclient/silcapi.h.
2957 * Fixed memory leaks in silc_client_close_connection. Affected
2958 file lib/silcclient/client.c.
2960 * Added silc_client_del_client_entry to client library to free
2961 all memory of given client entry. Affected file is
2962 lib/silcclient/idlist.[ch].
2964 * Added new functions silc_client_del_channel and
2965 silc_client_del_server to delete channel and server entries.
2966 Affected file lib/silcclient/[silcapi.h/idlist.c].
2968 * Removed silc_client_del_client_by_id from silcapi.h.
2970 * Fixed the INFO command to return the server's own info
2971 correctly when querying by Server ID. Affected file is
2974 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Removed the non-blocking settings in WIN32 code in the
2977 silc_sock_[read/write] and added SleepEx instead. Affected
2978 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2979 of input data is now checked with FIONREAD and ioctlsocket.
2981 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Call silc_schedule_task_del_by_context in the
2984 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2985 Affected file lib/silccore/silcprotocol.c.
2987 * Call silc_protocol_cancel for active protocols in the
2988 silc_server_close_connection if the funtion
2989 silc_server_free_sock_user_data has not been called.
2990 Affected file silcd/server.c.
2992 * Generic tasks cannot be deleted using the del_by_fd
2993 task deleting function since generic tasks does not match
2994 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2996 * Added a notion to SILCOPER help file that the SILCOPER works
2997 only on router server, not on normal server.
2999 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Added for WIN32 support for the new scheduler as well.
3002 Affected file lib/silcutil/win32/silcwin32schedule.c.
3004 * Fixed the SHA1 implementation to work on various platforms.
3006 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3009 API. It is part of the scheduler now. Everything else is
3010 as previously but some functions has changed their names.
3011 Checkout the lib/silcutil/silcschedule.h for the interface.
3012 Updated all applications to use the new interface. Affected
3013 files are lib/silcutil/silcschedule.[ch].
3015 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Found a bug in the SKE implementation. The HASH value,
3018 specified by the protocol, was not computed correctly. The
3019 public key of the responder was not added to the computation
3020 even though it is mandatory. Affected file lib/silcske/silcske.c.
3021 This unfortunately causes incompatibilities with older
3022 clients and servers.
3024 * Added WIN32 specific network init and uninit functions:
3025 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3026 the Winsock2. Affected file lib/silcutil/silcnet.h and
3027 lib/silcutil/win32/silcwin32net.c.
3029 * Set the socket always to nonblocking mode on WIN32 after
3030 reading data or writing data. Affected file is
3031 lib/silcutil/win32/silcwin32sockconn.c.
3033 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Fixed various compilation problems under WIN32. Affected
3036 files lib/silcutil/win32/silcwin32thread.c and
3037 lib/silcutil/win32/silcwin32schedule.c.
3039 * Removed all _internal.h #includes from public header
3040 files. Internal headers must never be included from
3043 Removed also the lib/silcske/payload_internal.h file.
3045 * All include files that may be needed (public and some others
3046 included by the public headers) by application developers are
3047 now copied to the ./includes directory. It does not copy any
3048 internal headers. Affected file Makefile.defines.pre and all
3049 Makefile.am's under lib/ and subdirs.
3051 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Do not change the ~/.silc directory's permissions automatically.
3054 Affected file irssi/src/silc/core/clientutil.c.
3056 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3058 * Do not cancel the protocol in silc_server_close_connection
3059 it might cause recursion. Now cancelled in the function
3060 silc_server_free_sock_user_data. Affected file silcd/server.c.
3062 * Fixed the silc_server_remove_clients_by_server to regenerate
3063 the channel keys correctly finally. Added also new function
3064 silc_server_remove_clients_channels to actually do it.
3065 Affected file silcd/server.c.
3067 * Fixed the silc_server_new_channel to not crash by giving
3068 wrong router to the new channel. Affected file is
3069 silcd/packet_receive.c.
3071 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3074 which is given as argument to the silc_client_alloc now.
3075 It can be used to configure the client and set various parameters
3076 that affect the function of the client.
3078 * The USERS command in server did not check whether the channel
3079 is private or secret. Affected file silcd/command.c.
3081 * Added new argument to the USERS command in protocol specification.
3082 The USERS command now can take the channel name as argument
3083 as well. Added support for this in client and server and
3084 updated the protocol specs.
3086 * Completed the GETKEY command in client. It can be now used
3087 to fetch also servers public key not only some clients.
3088 Affected files lib/silcclient/command[_reply].c.
3090 * Added silc_client_get_server to return server entry by the
3091 server name. Affected files lib/silcclient/silcapi.h and
3094 * Redefined the IDENTIFY command in protocol specification to be
3095 more generic. It now can be used to query information about
3096 any entity in the SILC Network, including clients, servers and
3097 channels. The query may be based either the entity's name
3098 or the ID. Added support for this in both client and server.
3100 Affected files silcd/command.c and lib/silcclient/command.c
3101 and command_reply.c.
3103 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3104 the _from_client and _from_server functions. Affected file
3107 * Added silc_client_get_channel_by_id_resolve to the file
3108 lib/silcclient/silcapi.h to resolve channel information by
3109 its ID. Added also silc_client_get_channel_by_id that
3110 does not resolve it from the server.
3112 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Added SilcServerEntry context into the client library
3115 to represent one server. The INFO command now allocates
3116 these to save the resolved server info. For now on the
3117 client library will also keep information about servers,
3118 connected and resolved with INFO.
3120 The INFO command now allocates the SilcServerEntry context
3121 and saves the server info there. The COMMAND_REPLY in
3122 the INFO now returns the parameters to application in
3123 same order as defined in the protocol specification.
3125 The entries are cached in the client->server_cache.
3127 * The INFO command is now issued after received the Client ID
3128 from the server. Affected file lib/silcclient/client.c.
3130 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3131 to the application as the mode changer might be server.
3132 It is guaranteed that NULL is not returned anymore to the
3133 application. Affected file lib/silcclient/client_notify.c.
3135 The ID Type is now also passed to the application so that
3136 it can check whether the returned entry is SilcClientEntry
3139 Added new function silc_client_get_server_by_id to return
3140 the server entry by ID. Affected files are the
3141 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3143 * Do not create the channel in the Irssi SILC Client when issuing
3144 the JOIN command but when received the sucessful JOIN command
3145 reply. Otherwise the channel might get created even though we
3146 could not join it. The Affected file is
3147 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3149 * Fixed a channel joining bug in router. The router must also
3150 check the channel modes, invite and ban lists etc. when serving
3151 the JOIN command sent by normal server. Affected file is
3152 silcd/command.c. The router now resolves the client's
3153 information from the server who sent the JOIN command if it
3154 does not know it, and processes the JOIN command only after
3157 * Changed the SilcCommandCb to take new argument; void *context2.
3158 Affected file lib/silccore/silccommand.h
3160 The second argument in the command callbacks in the server now
3161 includes the SilcServerCommandReplyContext if the command was
3162 called as pending command callback from the command reply.
3163 Otherwise it is NULL. When called as pending the status of the
3164 command reply will be checked and if it was erronous the
3165 error will be sent to the original sender of the command.
3166 This way the client always receives the error messages even
3167 though the server was actually the one who received the error
3168 when it resent the command to router, for example. Affected
3169 files silcd/command[_reply].[ch].
3171 * Fixed sending WHOWAS command's error message to client if
3172 the requested client could not be found. It was missing.
3175 * Changed the CMODE and CUMODE commands reply arguments in the
3176 protocol specification. The Channel ID is now sent in both
3177 of the commands to identify the channel. Implemented this
3178 new feature to the client and server. Affected files
3179 lib/silcclient/command_reply.c and silcd/command.c.
3181 * Made better checks for invite and ban lists in the JOIN
3182 command in server. Affected file silcd/command.c.
3184 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3186 * The server now performs the incoming host IP/DNS lookup
3187 using the silc_socket_host_lookup and thus does not block
3188 the server anymore. Affected file silcd/server.c.
3190 * Completed the multi-thread support for SILC Scheduler in
3191 the lib/silcutil/silcschedule.c.
3193 * Fixed the configure.in.pre to detect the pthread correctly
3196 * Fixed a deadlock in silc_task_queue_wakeup in the file
3197 lib/silcutil/silctask.c.
3199 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3201 * Added new function silc_schedule_wakeup that is used in
3202 multi-threaded environment to wakeup the main thread's
3203 schduler. It needs to be used when a thread adds a new task
3204 or removes a task from task queues. After waking up, the
3205 scheduler will detect the task queue changes. If threads
3206 support is not compiled in this function has no effect.
3207 Implemented the wakeup mechanism to both Unix and WIN32
3208 systems. Affected files are lib/silcutil/silcschedule.[ch],
3209 lib/silcutil/unix/silcunixschedule.c and the
3210 lib/silcutil/win32/silcwin32schedule.c.
3212 * Added new function silc_task_queue_wakeup to wakeup the
3213 scheduler by the specified task queue. Affected file
3214 lib/silcutil/silctask.[ch].
3216 * The silc_socket_host_lookup_start now wakes up the scheduler
3217 after adding the timeout task. Affected file is
3218 lib/silcutil/silcsockconn.c.
3220 * The silc_socket_host_lookup is synchronous now if the threads
3221 support is not compiled in. However, the callback is still
3222 called asyncronously through the scheduler, anyway. Affected
3223 file lib/silcutil/silcsockconn.c.
3225 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3227 * Added new function silc_socket_host_lookup to perform
3228 asynchronous IP and FQDN lookups for the socket connection.
3229 Affected files lib/silcutil/silcsockconn.[ch].
3231 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3234 that may or may not compile the mutex support in.
3236 Changed the silc_mutex_alloc interface. It allocates the
3237 mutex now to the sent pointer and returns TRUE or FALSE.
3239 Affected file lib/silcutil/silcmutex.h.
3241 * Wrote the SILC Task Queue interface to support multi-threads.
3242 Affected file lib/silcutil/silctask.[ch].
3244 * Wrote the SILC Scheduler to support multi-threads. Affected
3245 file lib/silcutil/silcschedule.c.
3247 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3250 in lib/silcutil/win32/.
3252 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Defined SILC Mutex API and SILC Thread API and implemented
3255 them for Unix. Affected files are
3256 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3257 lib/silcutil/unix/silcunixmutex.c and
3258 lib/silcutil/unix/silcunixthread.c.
3260 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * Fixed the silc_server_remove_clients_by_server's channel
3263 key re-generation. The hash table handling was incorrect
3264 and would not work with many channels. Affected file is
3267 * Fixed some memory leaks around the server code.
3269 * Rewrote the silc_server_get_users_on_channel to support IPv6
3270 based Client ID's. Affected file silcd/server.c.
3272 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3273 specification. However, a separate document must be written
3274 to define the detailed signing procedure and the payload
3275 associated with the flag. Defined the flag to the
3276 lib/silccore/silcchannel.h as well.
3278 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3280 * Changed the dynamic tables to static size tables in the
3281 lib/silccrypt/silchmac.c.
3283 * Removed GCC dependencies from the code. A patch by cras.
3285 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * Do not show the error "Error receiving packet bla bla"
3288 in server if it really was not an error (-2 means that reading
3289 is pending). Affected file silcd/server.c.
3291 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Fixed a possible crash in silc_server_remove_clients_by_server
3294 in silcd/server.c. Fixed there also some memory leaks.
3296 * Fixed the silc_idlist_replace_client_id. It could replace
3297 wrong key in the hash table. Affected file silcd/idlist.c.
3299 * Do not check whether there are global users on the channel
3300 if the channel->global_users is FALSE. Affected functions
3301 silc_server_remove_from_one_channel and
3302 silc_server_remove_from_channels in silcd/server.c. Also,
3303 do not check if the removed client is local as we can be
3304 sure that global client was not removed from the channel
3305 and checking for global users is not needed.
3307 * The silc_server_remove_clients_by_server now re-generates
3308 the channel keys correctly for those channels that had
3309 clients removed from them. Affected file silcd/server.c.
3311 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Found the reason of random crashes in the server. We weren't
3314 ignoring the SIGPIPE signal (which can be sent in write())
3315 and it crashed the server. Affected file silcd/silcd.c.
3317 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3319 * Assure that sock->user_data is not NULL in the function
3320 silc_server_packet_send in silcd/packet_send.c.
3322 * Disconnect the remote connection if it could not be added
3323 to any ID lists in the server. The affected file is
3326 * Check in silc_server_packet_send[_real/dest] that the
3327 socket is not disconnecting and ignore the data if it is.
3328 Affected file silcd/packet_send.c.
3330 * Define inline to __inline on native WIN32 compilation.
3331 Affected file includes/silcwin32.h.
3333 * Added some explicit type casts for inline code since MSVC
3334 require them. Affected files lib/silcutil/silcbuffer.h,
3335 lib/trq/silcdlist.h and lib/trq/silclist.h.
3337 * Print warning in log files from now on if the packet
3338 decryption fails. Affected file silcd/server.c.
3340 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3342 * Changed the `say' client operation's interface to accept
3343 new `type' argument to indicate the type of the message sent
3344 by the library. The application may filter the library's
3345 messages according the type. The affected file is the
3346 lib/silcclient/silcapi.h.
3348 * Added two new functions to lib/silcclient/silcapi.h:
3349 silc_client_del_client and silc_client_del_client_by_id.
3350 Affected file lib/silcclient/idlist.c.
3352 * Moved the clientincludes.h from includes/ to silc/ and
3353 serverincludes.h from includes/ to silcd/.
3355 * The modes for the CMODE and CUMODE are now passed as
3356 uint32 for application with COMMAND_REPLY. The affected
3357 file is lib/silcclient/command_reply.c.
3359 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * /WHOIS without arguments shows client's own information.
3362 Affected file lib/silcclient/command.c.
3364 * Changed PING to not accept any arguments. The specs
3365 says that client can ping only the connected server so
3366 requiring an argument is not needed. Affected file is
3367 lib/silcclient/command.c.
3369 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3371 * Fixed a fatal bug in private message sending and reception
3372 encryption and decryption when using private message keys.
3373 The implementation was incorrect and did not follow the
3374 specification. It causd that some of the message were
3375 lost since it did not use the sending and receiving keys
3376 as the protocol suggests. This has been fixed and will cause
3377 incompatibilities with older clients when sending private
3378 message encrypted with private message keys. Affected files
3379 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3380 and various other in Irssi SILC Client.
3382 Added `responder' boolean argument to the functions
3383 silc_client_add_private_message_key[_ske] to indicate when
3384 the key is added as responder or initiator of the key
3387 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Removed the silc_ske_check_version function and created
3390 a SilcSKECheckVersion callback. Added also a function
3391 silc_ske_set_callbacks that is now used to set all SKE
3392 callbacks. The callback functions are not given to
3393 the SKE functions anymore, but this function is used to
3396 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3398 * Added `silc_version' argument to the silc_client_alloc
3399 to define the version of the application for the library.
3400 The library will use the version string to compare it
3401 against the remote host's (usually a server) version
3402 string. Affected file lib/silcclient/silcapi.h
3404 * Added the KE protocol context to Key Agreement context
3405 in client library so that we can abort the SKE if it
3406 is in process when we get timeout. Affected file is
3407 lib/silcclient/client_keyagr.c.
3409 * Do not resolve the client ID forever if it returns in the
3410 first time that such client does not exist. This was done
3411 for example with private message. Affected file is
3412 lib/silcclient/client_prvmsg.c.
3414 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Do not add regex.h for WIN32. The affected file
3417 includes/silcincludes.h.
3419 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3420 not work yet 100%. It generates the DLL's automatically
3421 when compiling with --with-win32 under cygwin.
3423 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3425 * lib/contrib/regex.c is not compiled on WIN32.
3427 * Added silc_net_get_socket_opt function to the
3428 lib/silcutil/silcnet.h.
3430 * Added includes/silcwin32.h for WIN32 specific includes
3433 * Do not use ptime structure or any of the posix process
3434 functions on WIN32 in lib/silccrypt/silrng.c.
3436 * Added silc_gettimeofday to provide generic function
3437 for struct timeval on all platforms. Added the function
3438 to lib/silcutil/silcutil.h.
3440 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3442 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3443 library as they clearly belong there. As a plus side we
3444 can make the actual socket connection routines platform
3447 Added also new generic function silc_socket_read and
3448 silc_socket_write (that used to be silc_packet_[read/write].
3449 The implementation of these are platform specific.
3451 * Added WIN32 specific routines of silc_socket_[read/write]
3452 to lib/silcutil/win32/silcwin32sockconn.c.
3454 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Added preliminary support for native WIN32 compilation under
3457 cygwin (using the -mno-cygwin option for GCC) to the
3458 ./configure.in.pre. The --with-win32 now prepares the
3459 compilation for native WIN32.
3461 * Rewrote the SILC Scheduler interface in the file
3462 lib/silcutil/silcschedule.h. The scheduler is now context
3463 based and does not have anymore any global static scheduler.
3464 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3465 and created lib/silcutil/win32 directory for WIN32 based
3468 * Added Unix specific network routines to the
3469 lib/silcutil/unix/silcunixnet.c and the old
3470 lib/silcutil/silcnet.c includes now only generic routines.
3472 Added WIN32 specific network routines to the
3473 lib/silcutil/win32/silcwin32net.c.
3475 * Added Unix specific utility functions from the
3476 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3478 * Added WIN32 SILC Scheduler to the file
3479 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3482 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Do not handle JOIN notify in the server if the target client
3485 is not registered (idata->registered == FALSE). The affected
3486 file is silcd/packet_receive.c.
3488 * Update the nickrec->founder in event_cumode in the Irssi SILC
3489 client. Affected file irssi/src/silc/core/silc-channels.c.
3491 * Fixed the CUMODE_CHANGE notify handling in the server when
3492 server and router are announcing their clients on channels.
3493 Now the mode changes are saved and notified correctly. The
3494 affected file is /silcd/packet_receive.c.
3496 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3497 They really did not replace the cache entry in the ID Cache.
3498 Now they do that. Affected file silcd/idlist.c.
3500 * Fixed the KICK notify handling in the Irssi SILC client to
3501 update the channel records so that the kicked client does not
3502 appear to be on the channel. The affected file is
3503 irssi/src/silc/core/silc-channels.c.
3505 * Always update the conn->current_channel when executing command
3506 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3508 * Fixed the KILL notify handling in Irssi SILC client to remove
3509 the killed client on all channels.
3511 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Fixed the silc_parse_command_line to remove extra spaces
3514 from the start and end of the arguments. Affected file is
3515 lib/silcutil/silcutil.c.
3517 * Cancel and free any active protocol in the function
3518 silc_server_close_connection. Affected file silcd/server.c.
3520 * Cancel and free any active protocol in the function
3521 silc_client_close_connction. Affected file is
3522 lib/silcclient/client.c.
3524 * Do not execute the KILL command for clients that are in
3525 history (ie. they are not in the network). Affected file is
3528 * Fixed KILL notify handling, client does not crash anymore.
3529 Affected file irssi/src/silc/core/silc-channels.c.
3531 * Reduced the default packet buffer size from 2048 to 1024 in
3532 lib/silccore/silcpacket.c.
3534 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3535 counter to the SKE context that is incresed when the SKE library
3536 performs async operation outside the library. If the outside
3537 process frees the SKE context and FREED status will be set
3538 and the library will detect after the sync operation that the
3539 libary is freed. The affected files are
3540 lib/silcske/silcske[_status].[ch].
3542 * Resolve the client entry information in the function
3543 silc_client_channel_message to assure that NULL pointer is not
3544 passed as client entry to the application. */
3546 * Fixed the task timeout calculation to assure that there is
3547 never negative timeouts. The affected file is
3548 lib/silcutil/silcschedule.c.
3550 * Fixed the channel user mode notification sending in server.
3551 It was sent point-to-point to the router (or to server by router)
3552 but it needs to be destined to a channel. The routines now
3553 supports sending the channel user mode notifys to the channels
3554 when announcing clients and channels. Affected files are
3555 silcd/server.c and silcd/packet_receive.c.
3557 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3558 It did not actually replace the old channel entry in the cache.
3559 Affected file lib/silcclient/client_notify.c.
3561 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Fixed a possible crash in silc_packet_send_prepare. It now
3564 assures always that there is enough space in the buffer and
3565 at the tail area of the buffer (for MAC).
3567 Fixed the inbound buffer reallocation in silc_packet_read.
3568 It was old code and did not handle the reallocation correctly.
3571 The affected file is lib/silccore/silcpacket.c.
3573 * Fixed buffer overflow in silc_parse_nickname in the file
3574 lib/silcutil/silcutil.c.
3576 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * make install generates new server keys only if there is not
3581 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3584 Added check that if the NOREPLY is set then we will not send
3585 the away message. This avoids infinite loop of away messages
3586 if both clients are away. The affected file is
3587 lib/silcclient/client_prvmsg.c.
3589 * Fixed client crash if /NICK was given without arguments.
3590 Affected file lib/silcclient/command.c.
3592 * Server does not send the invite list in INVITE command back
3593 to the client if the list was not altered. Added this notion
3594 to the protocol spec as well. Affected file silcd/command.c.
3596 Fixed possible crash in INVITE command by checking the
3597 value of silc_server_get_client_route command.
3599 * Fixed the INVITE notify type handling. The arguments are now
3600 taken in correct order and client does not crash. The affected
3601 file is irssi/src/silc/core/silc-channels.c.
3603 Removed the "Inviting xxx to channel" message from the
3604 client library away and let the application handle it.
3605 Affected file lib/silcclient/command.c. Added that message
3606 to Irssi SILC client's message formats.
3608 * Fixed CMODE command crash in client. It now checks the
3609 amount of arguments correctly and does not crash. The affected
3610 file is lib/silcclient/command.c.
3612 * Do not create new channel automatically in silc_channels_join
3613 but check whether the channel by that name already exists.
3614 Affected file irssi/silc/core/silc-channels.c.
3616 * Do not send the SERVER_SIGNOFF to router if the disconnected
3617 entity was the router. Affected file silcd/server.c.
3619 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3620 SILC client as it was missing from there.
3622 Added the handling of the KICK notify to the Irssi SILC client
3623 as it was missing. Added "you have been kicked" message to
3624 Irssi SILC client's message modules formats.
3626 Added the handing of the KILL notify to the Irssi SILC client
3627 as it was missing. Added the kill message module formats
3630 The affected file is irssi/src/silc/core/silc-channels.c.
3632 * The router did not save the channel mode the server announced.
3633 Affected file silcd/packet_receive.c.
3635 * Fixed a possible crash in INFO command in server. If the
3636 server did not provide the server info it crashed. Affected
3637 file silcd/command.c.
3639 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Fixed the GETKEY command in the server to check also the
3642 global list. Otherwise the GETKEY would not work correctly
3643 in normal SILC server. Affected file silcd/command.c.
3645 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Fixed GETKEY crash, it crashed if the command did not succseed.
3649 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3652 is now real and not just an macro interface to GMP.
3654 Removed the entire GMP from the source tree and imported new
3655 NSS MPI library instead. Reason for removing GMP is that it is
3656 extremely large and compiles extremely slow. The NSS MPI
3657 is only a few files and compiles in less than 10 seconds.
3658 The speed is also about the same as GMP. The MPI is imported
3659 to lib/silcmath/mpi.
3661 If the system has GMP installed we will still use the GMP.
3662 If it is not then the NSS MPI will be compiled.
3664 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Merged a long nickname (127 characters long) crash bugfix from
3667 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3669 * Merged a freed memory reference bugfix from Irssi CVS tree.
3670 Affected file irssi/src/core/commands.c.
3672 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Added the server's public key sving and verification to the
3675 server when performing the SKE. This was missing and the
3676 remote server's (or router's) public key was accepted without
3677 checking whether we have it previously or trust it at all.
3678 Affected file silcd/protocol.c.
3680 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Check in the silc_server_timeout_remote if protocol is active
3683 and make sure that the protocol's final callback is called so
3684 that all memory if freed. Affected file silcd/server.c.
3686 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * silc_server_whois_send_reply crashed the server if the nickname
3689 was 127 characters long. Affected file silcd/command.c.
3691 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Added sanity check to the silc_server_new_client. If the hostname
3694 is provided inside username then check that the provided hostname
3695 really is the same as the resolved one. If the hostname was not
3696 resolved then check it from the public key. Affected file is
3697 silcd/packet_receive.c.
3699 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3700 if the server disconnected us and the connection is not valid
3701 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3703 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3704 the library to the lib/silcutil/silcutil.[ch].
3706 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Close log file after open. Affected file
3709 lib/silcutil/silclog.c.
3711 * Check whether sock == NULL in silc_client_send_packet and return
3712 if it is. Affected file lib/silcclient/silcclient.c.
3714 * Check rec->entry == NULL in the Irssi SILC Client before
3715 sending the channel message. Affecte file is
3716 irssi/src/silc/core/silc-servers.c.
3718 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Merged a splitted window bugfix from Irssi CVS tree. The
3721 affected file is irssi/src/fe-text/textbuffer-view.c.
3723 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3724 It did not print nickname.
3726 * Improved the distributions system a bit.
3728 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3731 irssi/src/fe-text/gui-window.c.
3733 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3734 to in-active server. The affected file is
3735 irssi/src/silc/core/client_ops.c.
3737 * Resolve the client in USERS command reply if the entry does
3738 not have username resolved. The affected file is
3739 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3740 command to WHOIS command to really resolve stuff. The USERS
3741 is not used any more in any critical section so WHOIS can
3742 be used even though it might be slower than IDENTIFY.
3744 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3747 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Changed the protocol API a bit more consistent in the
3750 lib/silccore/silcprotocol.[ch].
3752 * Changed the following headers to ROBODoc format:
3754 lib/silccore/silcpayload.h
3755 lib/silccore/silcprotocol.h
3756 lib/silccore/silcsockconn.h
3758 All core library headers are now formatted.
3760 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Fixed a bug in Irssi SILC client; do not show that you are
3763 server/router operator if you really are not. Affected file is
3764 irssi/src/silc/core/client_ops.c.
3766 * Renamed silc_command_free_payload to silc_command_payload_free.
3767 Affected file lib/silccore/silccommand.h
3769 * Added silcmath.h to include the prototoypes of various routines
3770 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3773 * Changed the following headers to ROBODoc format:
3775 lib/silccore/silcchannel.h
3776 lib/silccore/silccommand.h
3777 lib/silccore/silcid.h
3778 lib/silccore/silcidcache.h
3779 lib/silccore/silcmode.h
3780 lib/silccore/silcnotify.h
3781 lib/silccore/silcpacket.h
3782 lib/silcmath/silcmath.h
3784 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Added checking to the server code not to start the server if
3787 ciphers and stuff are not configured properly. Affected files
3788 silcd/serverconfig.[h] and silcd/server.c.
3790 * Changed the layout of the header files of the public interfaces
3791 in the SILC libraries. The new layout supports ROBODoc
3792 documentation tool (and some others) so that it is easy to create
3793 a library reference manual. All the other headers and source
3794 code must still follow the CodingStyle document. Also source
3795 code must not include these ROBODoc stuffs, only the headers.
3796 Furthermore, all public interface headers must now be named
3797 by using `silc' prefix, example: silcapi.h, silccipher.h.
3798 Some files were renamed due to this. All the other headers
3799 must not be used as public interfaces. I will update the
3800 CodingStyle document later. Changed following headers, so far:
3802 lib/silcclient/silcapi.h
3803 lib/silccore/silcauth.h
3804 lib/silccore/silcprivate.h
3805 lib/silccrypt/silcdh.h
3807 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Removed silc_client_packet_send_flush from the client library
3812 as it is not needed. Affected file lib/silcclient/client.[ch].
3814 * Added printing of message of unresolved authentication method
3815 to the Irssi SILC client. Added it to the module formats.
3816 Removed the same message from the client library.
3818 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Added new distribution feature, DISTLABEL. Every distribution
3821 can define own preprocessor label that can be used in the
3822 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3823 file distributions, acconfig.h.pre and prepare.
3825 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Added Makefile.defines_int to include the actual definitions
3828 for Makefile.defines.in. Tested the new distribution system,
3829 created distributions and tested installation.
3831 * Added AWAY message printing to the Irssi SILC client. Added
3832 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3834 * Added SCONNECT command to call the SILC's CONNECT command.
3835 Cannot use CONNECT directly since Irssi uses that internally.
3836 Affected file irssi/src/silc/core/silc-servers.c.
3838 Added ACTION local command. It is same as ME command but takes
3839 the channel as mandatory argument.
3841 Rewrote some of the Irssi's help files to suite for SILC
3844 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Added Makefile.defines[.in] that should for now on be included
3847 in all Makefile.am file in the source tree. That file includes
3848 all common compilation definitions for SILC source tree.
3850 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Minor changes to the ./prepare script to change the package
3853 name according the distribution name to the configure.in.
3855 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Created new distribution system. Added file `distributions'
3858 that defines all the distributions that can be created out of
3859 the SILC source tree. The ./prepare script now reads that
3860 file to determine how to prepare the distributions. The
3861 first argument to the ./prepare is the name of the distribution
3862 and second is the version of the distribution. If given
3863 without arguments it creates the default (toolkit) distribution
3864 with the default version (defined in ./prepare).
3866 All Makefile.am files that are subject to the distributions
3867 are now named as Makefile.am.pre. These are ./Makefile.am
3868 and lib/Makefile.am. Others may be changed later.
3870 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Added invite list, ban list, some key management and connection
3873 error message printing to module formats in the Irssi SILC client.
3875 * Added new silc_client_set_away_message to set the away message
3876 that is back to the person who sent private message. The
3877 affected file lib/silcclient/silcapi.h and the
3878 lib/silcclient/client_prvmsg.c.
3880 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Fixed the private message sending in the Irssi SILC client,
3883 added local command KEY to the Irssi SILC client.
3885 Added key management and key agreement message formats to the
3886 irssi/src/fe-common/silc/module-formats.[ch].
3888 Added USERS (alias WHO) printing, server/router operator
3889 indication and LIST command printing to the module formats.
3891 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Fixed channel joining notify handling, cumode notify handling
3894 from Irssi SILC client.
3896 * Added SILC specific module-formats to the Irssi SILC client so
3897 that SILC specific message hilighting, colors etc is possible.
3898 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3900 Added channel mode, channel user mode, actions, notices,
3901 whois and whowas printing to the the module-formats.c.
3903 * Fixed a bug in channel deletion in the server. The channel
3904 is not left to the cache even if the channel founder auth mode
3905 is set when there are no users anymore on the channel. Affected
3906 file silcd/server.c.
3908 * The silc_net_localhost now resolves the entire hostname including
3909 the domain name. Affected file lib/silcutil/silcnet.c.
3911 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Changed the ask_passphrase client operation to be ascynchronous.
3914 It has now a completion callback and a context that the
3915 application must call after it has got the passphrase from
3916 the user. Affected files lib/silcclient/silcapi.h,
3917 lib/silcclient/protocol.c, lib/silcclient/command.c and
3920 Added SilcAskPassphrase callback that the application calls
3921 to deliver the passphrase to the library.
3923 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3924 The public key verification and especially a certificate
3925 verification is asynchronous procedure.
3927 Added new SILC_SKE_STATUS_PENDING status to indicate the
3928 request is pending and a callback will be called to finalize
3931 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3932 indicate that remote end did not send its public key (or
3933 certificate), even though we require it. Added check for this
3934 condition in the SKE. This was a security bug, now fixed.
3936 Defined new SilcSKEVerifyCbCompletion callback that is called
3937 when the verification process is completed.
3939 The affected files lib/silcske/silcske_status.h and
3940 lib/silcske/silcske.[ch].
3942 * Changed the verify_public_key client operation to be async
3943 as well. Defined SilcVerifyPublicKey callback that is used to
3944 indicate the success of the public key verification process.
3946 Changed the server and client to use the new async client
3949 * Changed the Irssi SILC client's internal scheduler to be called
3950 twice as many times as it used to be. As a result the client
3951 should be a bit faster now. Affected file is
3952 irssi/src/silc/core/silc-core.c.
3954 * Added support to Irssi SILC client of asynchronous public key
3955 verification and passphrase inquiry. Affected file is
3956 irssi/src/silc/core/silc-core.c.
3958 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Do not say "You have left channel %s" in client library.
3961 Moved it to the application. Affected files are
3962 lib/silcclient/command.c and silc/client_ops.c.
3964 * Fixed silc_client_get_clients. Command context was not
3965 duplicated and was freed memory in the callback. Affected
3966 file lib/silcclient/idlist.c.
3968 * Do not say "you are now talking..." on JOIN command in the
3969 client library. The appliation must handle it.
3971 * Do not say ".. changed topic to" in command reply in the
3972 client libary. The application must handle it.
3974 * Fixed TOPIC command sending in the client library.
3976 * Fixed a memory leak in silc_client_command_free in the file
3977 lib/silcclient/command.c.
3979 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Imported a modified version of Irssi client to the source tree.
3982 The Irssi will be used to create a new client called
3983 Irssi SILC. Imported to irssi/.
3985 Added silc_core_init_finish function to the Irssi. Affected
3986 file irssi/configure.in.
3988 A lot changes in the Makefile.ams around the irssi tree.
3990 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Do not rehash if the new size is same as the old size of the
3993 hash table, in the silc_hash_table_rehash*. The affected file
3994 lib/silcutil/silchashtable.c.
3996 * Replaced hash_table_del_by_context calls from the server
3997 (when channel->user_list and client->channels) to the
3998 hash_table_del as it is sufficient and faster.
4000 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Added silc_hash_table_list, silc_hash_table_get and the
4003 SilcHashTableList structure to provide an alternative way to
4004 traverse the hash table. The affected files are
4005 lib/silcutil/silchashtable.[ch].
4007 * Changed the server's idlist routines to use the hash table
4008 routines to optimize the code.
4010 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Replaced the client entry's `channel' list and channel entry's
4013 `user_list' list to hash tables for optimized lookup. Changed
4014 the code to use the hash table interface around the code.
4015 Affected file lib/silcd/idlist.[ch].
4017 * Added `auto_rehash' boolean argument to the function
4018 silc_hash_table_alloc to indicate whether the hash table should
4019 auto-rehash when it thinks is appropriate time. It will
4020 increase the hash table size if the there is twice as much
4021 entries in the table than the size of the table, and will
4022 decrease the size if there are twice as less entries than
4023 the size of the table.
4025 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4029 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * silc_idcache_purge_by_context deletes the entry now by context
4032 as it is supposed to do. Affected file lib/silccore/idcache.c.
4034 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4035 client is not anymore valid (WHOWAS givens the info) and not
4036 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4038 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Removed the `data' and `data_len' arguments from the ID Cache
4041 interfaces and added `name' argument. ID Cache does not handle
4042 anymore the binary data only a names associated with given ID.
4044 * When hashing a Client ID with silc_hash_id the entire ID is
4045 not hashed anymore, instead only the hash of the Client ID is
4046 hashed. This way we can access the Client ID from the cache
4047 with Client ID but with the hash of the ID (which is a hash of
4048 the nickname) as well without any difference in performance.
4050 Added also silc_idcache_find_by_id_one_ext to do one on one
4051 searching when we have the actual ID. Added also function
4052 silc_hash_client_id_compare. The affected files are
4053 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4055 * When hashing the name associated with a ID it is always done
4056 in lowercase. This way we can access the cache without worrying
4057 about case-sensitivity, even though, for example nicknames are
4060 * Fixed a bug in server with channel message sending. It put
4061 wrong ID type as destination ID. The affected file
4062 silcd/packet_send.c.
4064 * silc_idcache_del_by_context now deletes from all hash tables
4065 by context. Affected file lib/silccore/idcache.c.
4067 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Changed the client library to use the new ID Cache interface.
4070 Changes around the source tree.
4072 * Added silc_hash_table_rehash_ext to rehash with specific
4073 hash function. Affected file lib/silcutil/silchashtable.[ch].
4075 * Added silc_hash_string_compare to compare two strings in the
4076 hash table. Affected file lib/silcutil/silcutil.[ch].
4078 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Added new function silc_idcache_del_by_context into the
4081 lib/silccore/idcache.[ch].
4083 * Changed the server's ID list routines to use the new ID Cache
4084 interface. Changes around the source tree.
4086 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Added silc_hash_table_del[_by_context]_ext functions in to the
4089 lib/silcutil/silchashtable.[ch].
4091 Removed silc_hash_table_find_all* routines and added new
4092 silc_hash_table_find_foreach to replace them.
4094 Added silc_hash_table_replace_ext function as extended
4095 replacing function. Separated the simple hash table interface
4096 from the extended hash table interface in the file
4097 lib/silcutil/silchashtable.h.
4099 * Fixed minor bugs and changed it to use some of the new
4100 hash table functions in lib/silccore/idcache.c
4102 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added new function silc_hash_table_find_all to return all keys
4105 in the hash table by the specified key. As the hash table is
4106 collision resistant it also makes it possible to have several
4107 duplicate keys in the hash table. This function may be used to
4108 find all of the keys from the hash.
4110 Added user_context arguments to the SilcHashFunction,
4111 SilcHashCompare and SilcHashDestructor to deliver user specified
4114 Added new fuctions silc_hash_table_find[_all]_ext to do
4115 extended lookup with specified hash and compare functions and
4116 specified user contexts.
4118 Added new function silc_hash_table_add_ext to add the key
4119 with specified hash function and user context.
4121 Added new function silc_hash_table_foreach to traverse all
4122 entrys in the hash table. Added SilcHashForeach callback
4125 Added new function silc_hash_table_del_by_context to delete
4126 the entry only if the context associated with the key matches.
4128 Affected files are lib/silcutil/silchashtable.[ch].
4130 * Removed silc_hash_[server/client/channel]_id and added just
4131 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4132 silc_hash_id_compare to compare two ID's using as the hash table
4133 comparison function. Added also silc_hash_data to hash
4134 binary data and silc_hash_data_compare to compare it.
4136 * Removed silc_idlist_find_client_by_hash as it is not needed
4137 anymore. Affected file silcd/idlist.[ch].
4139 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4140 to use internally the SilcHashTable. The new ID Cache is a lot
4141 faster than the old one. Some of the ID Cache interface was also
4142 rewritten and obsolete and stupid functions were removed.
4144 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Added entry_count field to the SilcHashTable to keep the number
4147 of the entries in the table. Implemented the function
4148 silc_hash_table_rehash. Added new function
4149 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4151 Fixed a minor bug in silc_hash_table_free.
4153 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4154 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4155 into the lib/silcutil/silcutil.[ch].
4157 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Implemented a collision resistant hash table into the
4160 lib/silcutil/silchashtable[ch]. See the header and the source
4161 for the SilcHashTable API.
4163 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Merged dotconf version 1.0.2 into lib/dotconf.
4167 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Do not compile anything in lib/silcsim/* if the SIM support
4170 is not enabled. The tree should now compile without problems
4173 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Compiled the SILC under cygwin. Compiled and tested briefly
4176 without problems. More tests needed. The SIMs didn't compile
4179 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4181 * Fixed possible crash in silc_get_username in the
4182 lib/silcutil/silcutil.c.
4184 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Fixed a va_arg in silc/client_ops.c.
4188 * Oops, RC5 routines were named AES and caused some problems
4189 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4191 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Added new SilcIDIP structure into the lib/silccore/id.h and
4194 replaced the old `ip' fields from all SILC ID's to that type.
4195 This is a step towards IPv6 support.
4197 The silc_id_get_len takes now the ID as an extra argument.
4198 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4199 both IPv4 and IPv6 based ID's.
4201 The affected files are lib/silccore/id.[ch] and other files
4202 around the tree using these routines.
4204 * Removed the ID length arguments in server from various
4205 silc_server_send_notify_* routines -> they are not needed
4208 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Fixed memory leak in silc_encode_pem_file in the file
4211 lib/silcutil/silcutil.c.
4213 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Check minor version as well in the SKE. Affected files are
4216 silcd/protocol.c and lib/silcclient/protocol.c.
4218 * Added --identifier option to the server so that an identifier
4219 can be when creating the public key for the server. Affected
4220 file is silcd/silcd.c.
4222 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4223 lib/silccrypt/silcpkcs.c.
4225 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Register default ciphers and stuff when using -C option with
4228 the server. Affected file sildc/silcd.c.
4230 * Put back the servers public key filename format, it is better
4231 than the new one. For now, the client keys are saved with the
4232 new filename format. The affected file silc/client_ops.c.
4234 * Implemented the Cipher API for the rest of the ciphers that
4235 did not implement it or implemented it the wrong way.
4237 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Register default ciphers and stuff when using the -S option
4240 in the client. Affected file silc/silc.c. Same also when
4241 creating new key pair with -C option.
4243 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Fixed the silc_verify_public_key client operation function to
4246 save the public keys differently. The fingerprint is now
4247 used as filename and not the hostname. This way also the
4248 client keys are saved uniquely and not with hostnames. The
4249 affected file is silc/client_ops.c.
4251 * Trimmed the silc_hash_fingerprint function to remove extra
4252 whitespaces from the end of the fingerprint. The affected
4253 file is lib/silccrypt/silchash.c.
4257 * Added silc_cipher_register_default function to register all
4258 default ciphers. It can be used when configuration files
4259 does not exist and the application does not want any specific
4260 ciphers in any specific order.
4262 The SilcDList is now used as silc_cipher_list dynamically
4263 allocated cipher list. Removed the static list all together
4264 and now all ciphers must be allocated to the dynamic list.
4265 The silc_cipher_alloc routine was changed to check only the
4268 All silc_cipher_* routines that used to return int returns
4271 The affected files lib/silccrypt/silccrypt.[ch].
4273 * The same thing was done to silc_hash_* as for silc_cipher_*
4274 routines. Affected files lib/silccrypt/silchash.[ch].
4276 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4277 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4278 Added also silc_pkcs_[un]register[_default] functions.
4279 Removed the data_context from the PKCS API.
4281 * Added silc_hmac_register_default function to register default
4282 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4283 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4284 to unregister all hmacs at once.
4286 * Register the default ciphers, hash functions, PKCSs and HMACs
4287 if client's configuration file does not exist. The affected
4290 * The client did not load the hash functions from the SIM
4291 modules at all. Added support for this. Affected file is
4292 silc/clientconfig.c.
4294 * When decoding public key with silc_pkcs_public_key_decode, check
4295 the supported algorithm only if PKCS are registered. Affected
4296 file lib/silccrypt/silcpkcs.c. The same was done with the
4297 silc_pkcs_private_key_decode.
4299 * Fixed the SILC List routines to keep the list always in order.
4300 It used to change the list's order when traversing the list but
4301 not it preserves the order. Affected file lib/trq/silclist.h.
4303 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Added the client library to use the SilcSocketConnection's
4306 reference counter (by silc_socket_dup) to prevent the bug that
4307 the socket object may be freed underneath async operation.
4309 * The name resolv library checking fixes in the configure.in.pre.
4312 * Created new version of the protocol drafts for future
4313 development. The -03 drafts are the ones that will be changed
4314 in the trunk now and the -02 will remain as they are.
4316 * Send list of CUMODE notifys to the router when announcing
4317 the channel users to the router. Affected file silcd/server.c.
4318 If the router receiving channel founder CUMODE for a channel
4319 that already has channel founder it will send CUMODE notify
4320 to the sender to remove the channel founder rights from the
4321 announced client. Affected file silcd/packet_receive.c.
4323 * The CUMODE notify may now use Server ID as well as the entity
4324 who changes the mode. Updated protocool specs.
4326 * Updated INSTALL and README files.
4328 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * New web pages in the http://silc.pspt.fi. The pages was
4335 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Implemented the [DenyConnectin] config section in the server.
4338 Added silc_server_config_denied_conn to check whether incoming
4339 connection is denied. Affected file silcd/serverconfig.[ch].
4341 * Do not check the ports when checking the incoming configuration
4342 data if the port is 0, meaning any. Affected file is
4343 silcd/serverconfig.c.
4345 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Fixed buffer overflow in silc_string_compare in the file
4348 lib/silcutil/silcutil.c.
4350 * Fixed double free in silc_server_command_leave in the file
4353 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Fixed the version checking in the server. Affected file is
4358 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Fixed the configuration data fetching when accepting new
4361 connections in the server. Affected file silcd/server.c.
4363 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Added `sender_entry' argument to the function
4366 silc_server_packet_relay_to_channel so that we can check
4367 whether some destination actually belongs to the same route
4368 the sender belongs (ie, we must not resend the packet to the
4369 sender). Affected file silcd/packet_send.[ch].
4371 * Added `servername' field to the SilcClientEntry in the server
4372 to hold the name of the server where client is from. Affected
4373 file is silcd/idlist.h.
4375 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Moved the channel message encrypting in the router betwen
4378 router connections from silc_server_channel_message to the
4379 silc_server_packet_relay_to_channel since we want to check
4380 whether we have anybody channel before encrypting anything.
4381 Affected files silcd/packet_[receive/send].c.
4383 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Fixed the [AdminConnection] server config section to support
4386 multiple entries. Affected file silcd/serverconfig.c.
4388 * Added support into the server to check the validity of the
4389 incoming connection before executing any KE or authentication
4392 * The connection configuration is now saved to the KE and
4393 connection auth protocol contexts and not fetched anymore in
4394 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4396 * The local hosts listenning address and port is also resolved
4397 now when starting the server. We want to have the socket object
4398 to include the real address and port for the listener. Added
4399 new function silc_net_check_local_by_sock into the files
4400 lib/silcutil/silcnet.[ch].
4402 * Fixed a broadcast bug in server -> do not broadcast if we
4405 * Fixed a routing bug. Do not route broadcast packets ever.
4406 Broadcast packets must be processed always and not routed since
4407 they may be destined to some other host than yourself and thus
4408 would get routed without no good reason. Affected file is
4411 * Added function silc_server_config_is_primary_route to check
4412 whether primary router connection has been configured (a router
4413 configuration that we are initiating). If there is not, we
4414 will assume that there is only two routers in the SILC network
4415 and we will use the incoming router connection as our primary
4416 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4418 * Changed the order of the broadcasting. Broadcast _after_ the
4419 packet has been processed not before. Affected file is
4422 * Fixed a [ClientConnection] parsing bug. The port was never
4423 parsed correctly thus resulting to port 0. Affected file
4424 silcd/serverconfig.c.
4426 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4427 argument and did not set the broadcast packet flag. Affected
4428 file silcd/packet_send.c. Fixed same bug in the function
4429 silc_server_send_notify as well.
4431 * If we receive NEW_ID packet for our own ID in the server, ignore
4434 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Removed the nickname from the Private Message Payload.
4439 Updated the code and the protocol specs.
4441 * Updated protocol specs for submitting to the IETF.
4443 * Tweaked the Random Number Generator a bit. Affected file
4444 lib/silccrypt/silcrng.c. Exported a new function
4445 silc_rng_[global]_add_noise which can be used to add more
4448 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Do not parse packets with different timeout when protocol
4451 is active -> may cause problem with rekey. Affected file
4454 * When server receives signoff notify it must not create
4455 new channel key if the client is on any channels since the
4456 sender of the signoff notify will create it.
4458 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added printing of error messages during SKE protocol from the
4461 failure packet sent by server during SKE. Affected file
4464 * Removed the client's failure_callback handling with timeout
4465 and handle it immediately when received.
4467 * The SKE library returned wrong type in SUCCESS and FAILURE
4468 packets. They must be 32 bit MSB not 16 bit MSB.
4470 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Ok, rewrote the logic of the re-key and now it seems to work.
4473 I tested it on high traffic with frequent re-keys without
4474 problems. Added hmac_receive (and renamed hmac to hmac_send)
4475 in SilcClientConnection in lib/silcclient/client.h and
4476 in SilcIDListData in silcd/idlist.h. Also, removed the
4477 SilcPacketParserContext's cipher and hmac fields as they are
4478 not needed anymore and actually caused some problems when
4479 the ciphers and hmac's changed underneath the packet parser.
4481 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * If re-key protocol is active then process the incoming packets
4484 synchronously since we must assure that icoming packets encrypted
4485 with the old key is processed before the new keys is set to
4486 use. This is true other packets than for REKEY packets.
4487 Affected file silcd/server.c. The same was done to client library
4488 as well, affected file lib/silcclient/client.c.
4490 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Fixed bug in client and server to accept the force send if
4493 the packet is send from silc_[server/client]_packet_process
4494 function. Otherwise the packets are never delivered, oops.
4496 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Disable force sending of packets when REKEY protocol is active.
4499 We must assure that no packet is sent directly when rekey is
4500 performed. All packets must be sent through packet queue.
4501 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4502 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4503 function is silc_[server/client]_packet_send_real to check
4506 * Replaced the SIM paths from example config files to
4507 /usr/local/modules. Also, make install creates now
4508 /usr/local/silc/logs directory to hold all the SILC server
4511 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Made the configure.in.pre work on Solaris. Patch by salo.
4515 * Made all ciphers compatible with non-x86 machines. Defined
4516 CBC mode macros into lib/silccrypt/ciphers_def.h.
4518 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Fixed the make install.
4522 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * When MAC computation fails the silc_packet_decrypt returned 0
4525 even though it was supposed to return -1. Fixed this. The
4526 affected file is lib/silccore/silcpacket.c.
4528 * Do not replace the config files in /etc/silc (in make install)
4529 if they already exist. Affected file ./Makefile.am.
4531 * Do not send re-key packets immediately but through packet queue.
4532 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4534 * Changed silc_net_check_host_by_sock to return FALSE if the
4535 IP/DNS could not be resolved. Though, it returns the IP address
4536 now even if it could not resolve it (but returns also FALSE).
4537 Affected file lib/silcutil/silcnet.[ch].
4539 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Added silc_pkcs_decode_identifier to decode the public key's
4542 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4543 Added also silc_pkcs_free_identifier. Added also new context
4544 SilcPublicKeyIdentifier.
4546 * Added -S option to the silc client. It is used to dump the
4547 contents of the specified public key file.
4549 * Changed the PKCS api to return the public key length when
4550 setting the public key.
4552 * Fixed a fatal bug in the public and private key file loading.
4553 Affected file lib/silccrypt/silcpkcs.c.
4555 * Execute the packet parsing for client with zero (0) timeout
4556 if the protocol is active. Affected file silcd/server.c.
4558 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Made the key generation options to the silcd program. Added
4561 -C option, equivalent to client's option.
4563 * Added new [ServerKeys] config section to the server. It
4564 configures the server's public and private key.
4566 * Defined generic Public Key Payload into the protocol
4567 specification to send specific type of public keys and
4570 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4571 public key or certificate.
4573 * Implemented the GETKEY command to the server and to the
4574 client library and on user interface.
4576 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Made preliminary `make install' work.
4580 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Added SilcServerRekey context into silcd/idlist.h.
4584 * Added the PFS support as defined in the specification to the
4585 SKE protocol. Affected files lib/silcske/*.c.
4587 * Added `ske_group' field to the SilcServerRekey context to hold
4588 the number of the SKE group that is used with PFS in re-key.
4589 Affected file silcd/idlist.h.
4591 * Added PFS re-key support to the server. Affected file is
4594 * Added silc_protocol_cancel to cancel execution of the next
4595 state of the protocol. Affected file is
4596 lib/silccore/silcprotocol.[ch].
4598 * Added the re-key support with and without PFS to the client
4599 library. Re-key is performed once in an hour, by default.
4601 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4602 Added silc_client_rekey_callback and silc_client_rekey_final.
4603 Affected files are lib/silcclient/protocol.[ch] and
4604 lib/silcclient/client.[ch].
4606 * Removed the `hmac_key' and `hmac_key_len' fields from the
4607 SilcClientConnection structure; not needed. Affected file is
4608 lib/silcclient/client.h.
4612 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Do not ask whether user wants to use the negotiated private key
4615 for private messages, just use it. Affected file is
4616 silc/local_command.c.
4618 * Added `send_enc_key' and `enc_key_len' fields to the
4619 SilcIDListData structure since they are needed in the re-key
4620 phase. Affected file is silcd/idlist.[ch].
4622 * Implemented the simple re-key protocol into the server.
4623 Affected files silcd/server.c and silcd/protocol.[ch]. The
4624 re-key will be performed once in an hour, by default.
4626 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4627 Added silc_server_rekey, silc_server_rekey_callback and
4628 silc_server_rekey_final.
4630 * Removed Tunneled flag from the protocol. Updated the code
4631 and the specifications.
4633 * Adde `pfs' field to the SilcIDListData to indicate whether
4634 the PFS is to be performed in the re-key. Affected file is
4637 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4640 int64 of at least the xintXX size. If void * is less that 4
4641 bytes uint32 * will be used. Defined bool as boolean.
4643 * Changed _ALL_ unsigned long and unsigned int to uint32,
4644 unsgined short to uint16 in the source tree.
4646 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4647 not handle clients that has entry->data.registered == FALSE.
4648 They are not in the network anymore. Affected file is
4651 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4653 * Implemented the sending of the SERVER_SIGNOFF notify in the
4654 server. Affected file is silcd/server.c.
4656 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4657 Added also silc_notify_payload_encode_args into the
4658 lib/silccore/silcnotify.[ch].
4660 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4661 Affected file silcd/packet_receive.c.
4663 * Implemented the SERVER_SIGNOFF notify handling in the client
4664 library. Affected file lib/silcclient/client_notify.c. Also,
4665 implemnted the printing of the SERVER_SIGNOFF info to the
4666 application. Affected file silc/client_ops.c.
4668 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4669 if the deleting was successful. Affected file silcd/idlist.[ch].
4671 * Added support for public key authentication in the connection
4672 authentication protocol in the client library. Affected file
4673 lib/silcclient/protocol.c.
4675 * Changed the server's silc_idlist_get_clients_by_* interface
4676 to support already allocated array so that new entries may be
4677 added to pre-allocated array. Affected file silcd/idlist.[ch].
4678 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4679 and command replies.
4681 * All command reply functions in the server now calls the
4682 pending command callback even if error occured. This way the
4683 error will be delivered to the client as well. Affected files
4684 silcd/command.c and silcd/command_reply.c.
4686 * Fixed INFO command to return local server's info if no server
4687 was provided. Affected file lib/silcclient/command.c.
4689 * Removed RESTART command for good. Updated the code and the
4692 * Rewrote parts of the task system. It is a bit simpler now.
4693 Removed unsued task priorities. The affected files are
4694 lib/silcutil/silctask.[ch].
4696 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Moved the USERS printing from the library to the application.
4699 Affected files lib/silcclient/command.c and silc/client_ops.c.
4701 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Added channel key re-key support. The re-key is perfomed
4706 only by the router and is done once in an hour. Added `rekey'
4707 field to the SilcChannelEntry in the server. Affected files
4708 silcd/server.c and silcd/idlist.h.
4710 * Added silc_task_unregister_by_context into the file
4711 lib/silcutil/silctask.[ch].
4713 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added SILC_UMODE_GONE mode to indicate when the client is not
4716 present in the SILC network. Added also support to the local
4717 command AWAY that will set this mode. Added support of showing
4718 "xxx is gone" in WHOIS command. The USERS command shows the
4719 gone status as well.
4721 * Fixed setting server and router operator privileges in the
4722 server's UMODE command. Affected file silcd/command.c.
4724 * Merged the SKE KE1 and KE2 payloads into one payload. The
4725 new KE payload is equivalent to the old KE2 payload.
4727 Cleaned up the SKE Start Payload parsing. It now uses the
4728 simple buffer unformatting to do the parsing. A lot faster
4731 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4732 to the SKE that is used to indicate whether both of the SKE
4733 parties should perform authentication. By default only the
4734 responder performs authentication. By setting this flag also
4735 the initiator must do authentication. By default it is unset
4736 since in normal SKE case, client to server connection, only
4737 the responder should do authentication. When doing SKE between
4738 two clients both should perform authentication. Updated the
4739 code and the protocol specs.
4741 * A little fix to IDENTIFY command in the server. Search the
4742 client first by hash not nickname. Affected file is
4745 * Fixed the silc_client_close_connection to support closing
4746 the client to client connections wihtout deleting too much
4747 data. Affected file lib/silcclient/client.c.
4749 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4750 are received if protocol used to be active but is not anymore
4751 the application would crash due to NULL pointer dereference.
4752 Affected files silcd/server.c and lib/silcclient/client.c.
4754 * Added `hash' field to the SilcClientConnection to include
4755 the hash function negotiated in the SKE protocol.
4757 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4758 to set the channel founder authentication data. A client can
4759 claim the founder rights later by providing the authentication
4760 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4761 This way the channel founder can regain the channel founder
4762 privileges even it is left the channel. This works only on
4763 local server and the client must be connected to the same
4764 server to be able to regain the founder rights. Updated the
4765 protocol specs accordingly.
4767 Added support to the CMODE command in the client to set the
4768 founder auth data. Read the README to see how to set it.
4770 Added support to the CUMODE command to claim the founder
4771 rights. Read the README to see how to do it.
4773 Added support for the founder authentication to the Channel
4774 Entry in the server. Affected file silcd/idlist.h.
4776 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4777 server's CMODE command. Affected file silcd/command.c.
4779 * Added the following new functions into lib/silccore/silcauth.[ch]:
4780 silc_auth_get_method and silc_auth_get_data.
4782 * The server now saves the remote hosts public key to the
4783 SilcIDListData pointer. Affected file silcd/protocol.c.
4785 * The normal server now does not remove the channel entry from
4786 the cache if the founder authentication data is set. It used
4787 to remove it if the founder was the last one on the channel on
4788 the server and left the channel. The auth data is saved and
4789 if the channel is re-joined later the old entry is used with
4790 the old auth data. Affected files silcd/command_reply.c and
4793 * Removed the `pkcs' field from the SilcIDListData structure
4794 in the server; it is not used. Affected file silcd/idlist.h.
4796 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Fixed packet processing on slow links. Partial packets were
4799 never re-processed because the incoming data buffer was cleared
4800 by the application. Application must not directly clear the
4801 sock->inbuf, the packet processing routines handle it. Fixed
4802 this in client library and in server.
4804 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Fixed the WHOIS and IDENTIFY send reply function to really
4807 check whether to send list or just one entry. Affected file
4810 * Cleaned up the LEAVE command's channel key distribution. The
4811 affected file silcd/command.c.
4813 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4814 can enforce the channel mode as well. In that case the ID
4815 includes the ID of the server. The code now enforces the
4816 mode change if the router have different mode than the server.
4818 * The notify client operation with CMODE_CHANGE notify can now
4819 return NULL client_entry pointer if the CMODE was not changed
4820 by client. Application must check for this.
4822 * Added <Server ID> argument to INFO command to support server
4823 info fetching by Server ID.
4825 * Added silc_server_announce_get_channel_users to get assembled
4826 packets of channel users of the specified channel. Affected
4827 file silcd/server.[ch].
4829 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4830 was freed underneath the ID Cache.
4832 * Re-announce clients when the server received CHANNEL_CHANGE
4833 notify from the router. Affected file silcd/packet_send.c.
4835 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4838 crashed since it did not handle the fact that there is no cipher
4839 called "3" and didn't check the error condition. Now fixed.
4841 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4842 flag. It can be used to send message requests.
4844 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Implemented the RESTART command in the client.
4848 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4849 notice type messages. Added notice printing to the user
4852 * The channel keys are not re-generated if the channel's mode
4853 is PRIVKEY, ie private key on the channel exists. Affected
4854 files silcd/server.c and silcd/command.c.
4856 * Fixed a little bug in channel message delivery when channel
4857 private keys are set in the server. Affected file is
4858 silcd/packet_send.c.
4860 * Changed the setting on channel->on_channel = TRUE from the
4861 silc_client_save_channel_key to the JOIN command reply. The
4862 key payload is not received if the private channel key is set.
4863 Affected file lib/silcclient/command_reply.c and the
4864 lib/silcclient/client_channel.c.
4866 * When the CMODE_CHANGE notify is sent and the channel private
4867 key mode is removed the channel key must be re-generated in
4868 other cells as well. Added this support for the router in the
4869 silcd/packet_receive.c.
4871 * Added new local command NOTICE to send notice message on
4872 channel. Affected file silc/local_command.[ch].
4874 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Added new local command ME to the client. It is used to send
4877 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4878 some action. Affected file silc/local_command.[ch].
4880 * Changed channel_message and private_message client operations
4881 to deliver the message flags to the application. Added also
4882 the `flags' arguments to the silc_client_send_channel_message
4883 and silc_client_send_private_message functions. Affected file
4886 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Redefined the Private Message Payload to support private message
4889 keys and to support the new private message flags. Updated
4890 the protocol specs. Flags makes it possible to have for example
4891 CTCP style messages.
4893 * Added new type SilcPrivateMessagePayload and defined an API
4894 for it in the lib/silcclient/silcprivate.[ch].
4896 * Tested private message private keys successfully. Tested the
4897 private message key set, unset and list commands with the new
4900 * Redefined the Channel Message Payload to include the channel
4901 message flags (equal with private message flags) to support
4902 for example CTCP style messages.
4904 * Defined some of the message (for channel and private message)
4905 flags. Updated the protocol specs and added the flags to the
4906 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4908 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Added SilcKeyAgreementStatus type to the key agreement routines
4911 to indicate the current status and error if one occured.
4912 The status types are defined in the lib/silcclient/silcapi.h.
4914 * Added new local command KEY that is used to set and unset private
4915 keys for channels, set and unset private keys for private messages
4916 with remote clients and to send key agreement requests and
4917 negotiate the key agreement protocol with remote client. The
4918 key agreement is supported only to negotiate private message keys,
4919 it currently cannot be used to negotiate private keys for channels,
4920 as it is not convenient for that purpose.
4922 * Fixed a minor pending callback setting bug in the function
4923 silc_client_get_client_by_id_resolve, now the function works.
4924 Affected file lib/silcclient/idlist.c.
4926 * Added function silc_net_get_local_port to get local bound
4927 port by socket. Added to lib/silcutil/silcnet.[ch].
4929 * Added `sockets' and `sockets_count' fields to the SilcClient
4930 object. They hold the sockets of the listenning sockets in
4931 the client. Listenning sockets may be for example the key
4932 agreement server. Affected file lib/silcclient/client.[ch].
4933 Added functions the silc_client_add_socket and the
4934 silc_client_del_socket. They are exported to the application
4937 * Added ~./silc/clientkeys to support other client's public keys.
4939 * Renamed verify_server_key client operation to verify_public_key
4940 and added one argument to indicate the type of the connection
4941 (server, client etc.).
4943 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Added silc_server_connection_auth_request to handle the
4946 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4947 silcd/packet_receive.[ch].
4949 * Added silc_server_send_connection_auth_request into the
4950 silcd/packet_send.c to send the connection auth request packet.
4952 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4955 * Fixed the public key authentication in responder side in the
4956 server. The `auth_data' pointer includes the SilcPublicKey
4957 not the path to the public key. Affected file silcd/protocol.c.
4959 * Implemented the public key authentication in the initiator side
4960 in the server. Affected file silcd/protocol.c.
4962 * Removed the [RedirectClient] config section from the server
4963 configuration. Is not needed and I don't want to implement it.
4965 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Cleaned up the CMODE command in the server. It now works
4968 correctly and supports all the modes defined in the protocol.
4969 Affected file is silcd/command.c.
4971 * Added `hmac_name' field to the SilcChannelEntry in the server
4972 to hold the default HMAC of the channel. It can be set when
4973 creating the channel (with JOIN command). Affected files
4976 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4977 type to indicate the change of the current cipher and hmac
4978 on the channel. Client can safely ignore the <cipher> argument
4979 (if it chooses to do so) since the CHANNEL_KEY packet will
4980 force the channel key change anyway. The <hmac> argument is
4981 important since the client is responsible of setting the new
4982 HMAC and the hmac key into use.
4984 * Fixed the CMODE command in the client library as well.
4986 * Tested CMODE command in router environment successfully.
4988 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Show the version of the remote client (or server) when connecting
4991 to the server. It is logged to the log file. Affected file
4992 is silcd/protocol.c.
4994 * Fixed the KILLED notify handling in the client library. The
4995 client must be removed from all channels when receiving the
4998 Also, do not remove the client entry when giving the KILL
4999 command but when the KILLED notify is received.
5001 * Removed silc_idlist_find_client_by_nickname from the server.
5002 Not needed anymore. Affected files silcd/idlist.[ch].
5004 * Implemented the CHANNEL_CHANGE notify type handling to the
5005 server. Affected file silcd/server.c.
5009 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added silc_server_send_notify_invite to send the INVITE
5012 notify between routers.
5014 * Implemented the INVITE command correctly to the server.
5016 * Implemented the INVITE notify type handling in the server.
5018 * Implemented the INVITE command to the client library and on the
5021 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Added function silc_server_get_client_resolve to find the
5024 client entry by ID from all ID lists and then resolve it
5025 (using WHOIS) if it cannot be found. Affected file is
5028 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Implemented the BAN command to the client library.
5032 * The JOIN command in the server now checks the invite list
5035 * Changed the silc_command_reply_payload_encode_va and the
5036 silc_command_payload_encode_va to support that if argument is
5037 NULL it ignores and checks the next argument. Affected file
5038 lib/silccore/silccommand.c.
5040 * Added silc_server_send_notify_ban to send the BAN notify
5041 type between routers.
5043 * Chaned the silc_notify_payload_encode to support that if
5044 argument is NULL it ignores and checks the next argument.
5045 Affected file lib/silccore/silcnotify.c.
5047 * Tested ban lists in router environment successfully.
5049 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Implemented BAN command to the server, in silcd/command.[ch].
5053 * Removed the BAN and INVITE_LIST modes from the CMODE command
5056 * Added function silc_string_match to regex match two strings.
5057 Affected files lib/silcutil/silcutil.[ch].
5059 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Redefined parts of the SilcChannelEntry in the server to support
5062 the new ban and invite lists.
5064 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Redefined the INVITE command. The same command can be used to
5067 invite individuals to the channel but also to manage the invite
5068 list of the channel (to add to and remove from the invite list).
5069 Updated the protocol specs.
5071 * Added new command SILC_COMMAND_BAN that can be used to manage
5072 the ban list of the channel. Updated the protocol specs.
5074 * Removed the channel modes: the SILC_CMODE_BAN and the
5075 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5076 in the CMODE command. The equivalent features are now available
5077 using INVITE and BAN commands. Updated the protocol specs.
5079 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5080 in the network about change in the current ban list. The notify
5081 type is not used by the client.
5083 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5084 support the invite lists.
5086 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Added new function silc_string_regexify that converts string
5089 including wildcard characters into regex string that can
5090 be used by the GNU regex library. Added into the file
5091 lib/silcutil/silcutil.[ch].
5093 Added silc_string_regex_combine to combine to regex strings
5094 into one so that they can be used as one regex string by
5095 the GNU regex library. Added into the file
5096 lib/silcutil/silcutil.[ch].
5098 Added silc_string_regex_match to match two strings. It returns
5099 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5101 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Imported GNU regex to the soruce tree into lib/contrib.
5104 Fixed some compiler warning from the regex.c.
5106 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Fixed MOTD command in the server to work in router environment.
5110 * Fixed the MOTD command in the client library to support
5111 the server argument in the command.
5113 * Added `nickname_len' argument to the silc_idlist_add_client
5114 in the server, as the `nickname' argument may be binary data
5117 * Added silc_idlist_get_channels to return all channels from
5120 * Implemented LIST command to the server. Affected file is
5123 * Implemented the LIST command to the client library and on the
5126 * Added [<user count>] argument to the LIST command reply.
5127 With private channels the user count is not shown.
5129 * Updated TODO and README.
5131 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * The client entry's data.registered must be TRUE even with
5134 global client entry on global client list. The data.registered
5135 is used to check whether the client is anymore in the network,
5136 for example with WHOWAS command so it must be valid.
5138 * Fixed the WHOWAS command in the server. It now actually works
5139 in router environment. Added function into silcd/command_reply.c
5140 silc_server_command_reply_whowas_save.
5142 * Added silc_idlist_purge function to the silcd/idlist.c
5143 to periodically purge the ID Cache.
5145 * Fixed INFO command in the server. It works now in router
5146 environment. Added <server name> argument to the INFO command
5147 reply. Updated the protocol specs.
5149 * Fixed minor bug in silc_idcache_purge to not purge if the
5150 expire value is zero.
5152 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5153 they were buggy because of the WHOWAS information.
5155 * Fixed local command MSG to handle the async resolving of
5156 the remote client properly. It used to fail the first MSG.
5157 Affected file silc/local_command.c.
5159 * Added `data_len' field to SilcIDCache context.
5161 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Update TODO. Todo in commands in the server.
5165 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5168 used by routers as broadcast packet to inform other routers
5169 about the changed user mode.
5171 Implemented the notify handling in the server. Affected file is
5172 silcd/packet_receive.c. Added the function
5173 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5175 * Added new generic Channel Payload and deprecated the New Channel
5176 Payload. The New Channel Payload is now the generic Channel
5179 * Added new argument `mode' to the silc_server_send_new_channel
5180 as it is required in the Channel Payload now.
5182 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5183 and created a new and real SilChannelPayload to represent the
5184 new generic Channel Payload. Implemented the encode/decode
5185 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5187 * Added silc_server_get_client_channel_list to return the list
5188 of channels the client has joined for WHOIS command reply.
5189 Affected file silcd/server.[ch].
5191 * Implemented the channel list sending in the WHOIS command reply
5192 in server and in the client.
5194 Implemented the channel list displaying on the user interface
5195 as well. Affected file silc/client_ops.c.
5197 * Added silc_channel_payload_parse_list to parse list of Channel
5198 Payloads. It returns SilcDList list of SilcChannelPayloads.
5199 Client for example can use this function to parse the list of
5200 channels it receives in the WHOIS command reply. The caller
5201 must free the list by calling silc_channel_payload_list_free.
5202 Affected files lib/silccore/silcchannel.[ch].
5204 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Added one new argument <user mode> to the WHOIS command reply
5207 to return the mode of the user in SILC. Updated the protocol
5210 Implemented it to the server and client.
5212 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Fixed the mode printing on the user interface on joining.
5215 Affected file silc/client_ops.c.
5217 * Implemented the UMODE command and user modes in general to the
5218 client library and to the user interface.
5220 * Implemented the UMODE command to the server.
5222 * The server now sends UNKNOWN_COMMAND error status if client sends
5223 unknown command. Affected file silcd/command.c.
5225 * All server commands now handle the command identifier the right
5226 way when sending the command reply to the client. The client can
5227 use to identify the command replies with the identifier.
5229 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Added silc_server_get_client_route to resolve the route to
5232 the client indicated by the client ID. Affected file is
5235 * Added silc_server_relay_packet as general function to relay
5236 packet to arbitrary destination. This deprecates functions
5237 like _send_private_message_key, _relay_notify etc. Affected
5238 file is silcd/packet_send.[ch].
5240 Removed silc_server_send_key_agreement,
5241 silc_server_send_private_message_key and
5242 silc_server_packet_relay_notify functions from the file
5243 silcd/packet_send.[ch].
5247 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5248 server. Affected file silcd/packet_receive.[ch].
5250 * Implemented the KILL command to the client. Implemented the
5251 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5252 Affected files lib/silcclient/command[_reply].c and
5253 lib/silcclient/client_notify.c. Implemented the KILL notify
5254 printing in the user inteface.
5256 * Fixed a lot silc_parse_nick memory leaks from the client
5257 library in the file lib/silcclient/command.c.
5259 * Changed the silc_server_send_notify_on_channels's `sender'
5260 argument from SilcSocketConnection to SilcClientEntry to
5261 check the sender as entry and not as connection object and not
5262 to send to the client provided as argument. The affected file
5263 is silcd/packet_send.[ch].
5265 * The notify packets that are destined directly to the client used
5266 to not to be processed by the server. Now changed that and the
5267 server processes all notify packets. After relaying the packet
5268 to the client the notify packet is processed in the server.
5270 * The silc_server_free_client_data now checks whether there is
5271 pending outgoing traffic for the client and purges the data to
5272 the network before removing the client entry.
5274 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5277 an client is killed from the SILC Network. Updated the protocol
5280 Added new function silc_server_send_notify_killed to the
5281 silcd/packet_send.[ch].
5283 * Added function silc_server_packet_relay_notify to relay notify
5284 packets that are destined directly to a client. In this case
5285 the server does not process the notify packets but merely relays
5286 it to the client. Affected file silcd/packet_send.[ch].
5288 Added also silc_server_packet_process_relay_notify to check
5289 whereto relay the notify. Affected file is
5290 silcd/packet_receive.[ch].
5292 * Implemented the KILL command to the server.
5296 * Added the backup schema desgined last fall to the protocol
5297 specs for everyone to see. The specification is in the
5298 *-spec-xx.txt draft and the packet type definitions for the
5299 backup routers is in *-pp-xx.txt draft. Thusly, added also
5300 new packet type SILC_PACKET_CELL_ROUTERS.
5302 * A big security problem in the implementation discovered. The
5303 signoff of an client did not cause new channel key generation
5304 which it of course should've done. The channel keys must be
5305 always re-generated when client leaves (or signoffs) the channel.
5306 The silc_server_remove_from_channels funtion now handles
5307 the channel key re-generation.
5309 * Added `sender' argument to the silc_server_send_notify_on_channels
5310 to not to send the client provided as argument. Affected file
5311 silcd/packet_send.[ch].
5313 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Implemented OPER and SILCOPER commands into the server and
5318 * Added silc_auth_verify and silc_auth_verify_data to verify
5319 the authentication directly from the authentication payload.
5320 It supports verifying both passphrase and public key based
5321 authentication. Affected file lib/silccore/silcauth.[ch].
5323 * Added `hash' field to the SilcIDListData structure. It is the
5324 hash negotiated in the SKE protocol. Affected file is
5327 * Slight redesigning of the SilcAuthPayload handling routines.
5328 Do not send SilcPKCS but SilcPublicKey as argument.
5330 * Implemented the public key authentication support to the
5331 serverconfig. The public key is loaded from the provided path
5332 and saved as authentication data to void * pointer. Thus,
5333 changed the unsigned char *auth_data to void *auth_data;
5335 * Fixed SHUTDOWN command to send the reply before the server
5336 is shutdown. :) Affected file silcd/command.c.
5338 * Fixed fatal bug in CONNECT command. The hostname was invalid
5339 memory and server crashed. Affected file silcd/command.c.
5341 * Fixed fatal bug in CLOSE command. The server_entry became
5342 invalid but was referenced later in the command. Affected file
5345 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * Fixed fatal bug in failure packet handling. Server ignored
5348 the failure and thus crashed when it came.
5352 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5355 that the command may be executed only once in (about) 2 seconds.
5356 The old SILC_CF_LAG flag is same but allows command bursts up
5357 to five before limiting.
5359 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5360 server code. Various commands now includes the CF_LAG_STRICT
5361 flag to disallow any kind of miss-use of the command.
5363 * Fixed the silc_buffer_unformat to not to allocate any data
5364 if the length of the data is zero. It used to allocate the
5365 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5367 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Changed the format of AdminConnection configuration section
5370 in the server. Added username of the admin to the format.
5371 Affected files silcd/serverconfig.[ch].
5373 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5374 to return admin configuration data by host, username and/or
5377 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Implemented WHOWAS command to the server. Added the functions:
5381 silc_server_command_whowas_parse,
5382 silc_server_command_whowas_send_reply,
5383 silc_server_command_whowas_from_client and
5384 silc_server_command_whowas_from_server
5386 * Added <Client ID> argument to the WHOWAS command reply. Updated
5387 the protocol specs accordingly.
5389 * Implemented WHOWAS command and command_reply to the client
5392 Implemented the WHOWAS printing on the user interface.
5394 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Added new argument to the WHOWAS command reply, the real name.
5397 It is an optional argument. Updated the protocol specs.
5399 * Added SilcIDCacheDestructor callback that is registered when
5400 the SilcIDCache is allocated. The callback is called when
5401 an cache entry in the ID Cache expires, or is purged from the
5402 cache. Added into lib/silccore/idcache.[ch].
5404 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5405 to destruct the client entries when the cache entry expires.
5406 Other ID Cache's in server and in the client library ignores
5409 * If the ID Cache entry's `expire' field is zero then the entry
5410 never expires. Added boolean `expire' argument to the
5411 silc_idcache_add function in the lib/silccore/idcache.[ch].
5412 If it is TRUE the default expiry value is used.
5414 * Added silc_server_free_client_data_timeout that is registered
5415 when client disconnects. By default for 5 minutes we preserve
5416 the client entry for history - for WHOWAS command.
5418 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Added support to the server to enforce that commands are not
5421 executed more than once in 2 seconds. If server receives
5422 commands from client more frequently, timeout is registered
5423 to process the commands. Affected file silcd/command.c.
5424 Added new function silc_server_command_process_timeout.
5426 * Changed NICK_NOTIFY handling in client library to check that
5427 if the client's nickname was changed, so there is no need to
5428 resolve anything from the server.
5430 * Removed error printing from the WHOIS and IDENTIFY commands.
5431 If error occurs then it is ignored silently in the client library.
5432 The application, however, may map the received error to
5433 human readable error string. The application currently maps
5434 the NO_SUCH_NICKNAME error to string.
5436 * Made the command status message public to the application. Moved
5437 them from lib/silcclient/command_reply.c to
5438 lib/silcclient/command_reply.h. The application can map the
5439 received command status to the string with the
5440 silc_client_command_status_message function.
5442 * Added check to the server to check that client's ID is same
5443 as the Source ID in the packet the client sent. They must
5446 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Added dist-bzip hook to the Makefile.am to make bzip2
5449 compressed distributions.
5451 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Server now enforces the maximum length for the nickname and
5454 the channel as protocol specification dictates. 128 bytes for
5455 nickname and 256 bytes for channel name.
5457 * Moved the WHOIS printing to the application. The client libary
5458 does not print out the WHOIS information anymore, the application
5459 must do it. Renamed silc_client_command_reply_whois_print to
5460 the silc_client_command_reply_whois_save.
5462 The client's idle time is also sent to the application now, and
5463 the idle is shown on screen.
5465 * Added silc_client_command_reply_identify_save to save the
5466 received IDENTIFY entries.
5468 * Do not check for channel private keys in message sending and
5469 reception if the channel does not have the PRIVKEY mode set.
5470 Affected file lib/silclient/client_channel.c.
5472 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5475 just surfaced after chaning the JOIN procedure.
5477 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Added silc_client_get_clients_by_list to get client entries
5480 from Client ID list, that is returned for example by JOIN
5481 and USERS command replies. The application should use this
5482 function for example when JOIN command reply is received to
5483 resolve the clients already on the channel (library does not
5484 do that anymore as USERS command reply is not used in the JOIN
5485 procedure anymore). Affected files lib/silcclient/silcapi.h and
5486 lib/silcclient/idlist.c.
5488 * JOIN command reply and USERS command reply returns now SilcBuffer
5489 pointers instead of unsigned char pointers when returning
5490 the client list and mode list.
5492 * Added <Client ID> argument to the JOIN command reply, mainly
5493 for the server to identify for which client the command was
5494 originally sent. Updated protocol specs accordingly.
5496 * Added SilcDlist private_key pointer to the SilcChannelEntry
5497 in the client to support the channel private keys. Affected
5498 file is lib/silcclient/idlist.h.
5500 * Added SilcChannelPrivateKey argument to the function
5501 silc_client_send_channel_message so that application can choose
5502 to use specific private ke if it wants to. If it is not provided,
5503 the normal channel key is used, unless private keys are set.
5504 In this case the first (key that was added first) is used
5505 as the encryption key.
5507 * Implemented the support for channel private key handling.
5508 Implemented the following functions:
5510 silc_client_add_channel_private_key,
5511 silc_client_del_channel_private_keys,
5512 silc_client_del_channel_private_key,
5513 silc_client_list_channel_private_keys and
5514 silc_client_free_channel_private_keys
5516 Affected file lib/silcclient/client_channel.c.
5518 * Added the support for the private keys in the channel message
5519 sending and encryption and in the message reception and
5520 decryption. Affected funtions are
5521 silc_client_send_channel_message and silc_client_channel_message.
5523 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added SKE's key verify callback to the client library's
5526 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5528 * Removed the statement that server (or router) must send USERS
5529 command reply when joining to the channel so that the client
5530 knows who are on the channel. Instead, the client list and
5531 client's mode list is now sent in the JOIN command reply to the
5532 client who joined channel. This is better solution.
5534 * Added function silc_server_get_users_on_channel and function
5535 silc_server_save_users_on_channel to the silcd/server.[ch].
5537 * Removed function silc_server_command_send_users from the
5540 * Do not show topic on the client library anymore. The topic is
5541 sent in the command reply notify to the application and the
5542 application must show the topic now.
5544 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Added client searching by nickname hash into the IDENTIFY and
5547 WHOIS commands in the server as they were clearly missing from
5548 them. Affected file is silcd/command.c.
5550 * Fixed a bug in private message receiving in the client library.
5551 The remote ID was freed and it wasn't supposed, now it is
5554 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Minor fix to the channel payload; allocate the data area, as it
5557 needs to be of specific length.
5559 * If the key agreement port is zero then the operating
5560 system will define the bound port. Affected files are
5561 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5563 * Added new function silc_channel_payload_decrypt into the file
5564 lib/silccore/silcchannel.[ch].
5566 * Moved the channel message etc, check from silc_packet_decrypt
5567 to applications. The library calls now a generic
5568 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5569 when the packet is either normal or special. This was done to
5570 allow more wide range of checking that was not allowed when
5571 the code was in library. Now applications can do virtually any
5572 checks to the packet and return to the library the decision how
5573 the packet should be processed. Affected files are
5574 lib/silccore/silcpacket.[ch].
5576 Added silc_server_packet_decrypt_check to the server and
5577 silc_client_packet_decrypt_check to the client library.
5579 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5580 to send with specified source and destination information.
5582 * Channel message delivery between routers was broken after the
5583 channel key distribution was fixed earlier. The channel key
5584 was used be to distributed to other routers as well which is not
5585 allowed by the protocol. Now this is fixed and channel keys
5586 really are cell specific and the channel message delivery between
5587 routers comply with the protocol specification.
5589 * Fixed various commands in server to check also the global list
5590 for the channel entry and not just the local list. The affected
5591 file silcd/command.c.
5593 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Added assert()s to buffer formatting and unformatting routines
5596 to assert (if --enable-debug) when error occurs. Affected
5597 file: lib/silcutil/silcbuffmt.c.
5599 * Changed to auto-reconnect to check whether the remote host is
5600 router and register the re-connect timeout if it is. It used
5601 to check that whether we are normal server, but router must do
5602 auto-reconnect with another router as well. Affected file
5605 * Removed the [<key len>] option from CMODE command as the cipher
5606 name decides the key length, nowadays. See the defined ciphers
5607 from the protocol specification.
5609 * Added [<hmac>] option to the CMODE command to define the HMAC
5610 for the channel. Added SILC_CMODE_HMAC channel mode.
5612 * Added [<hmac>] option for the JOIN command so that user can
5613 select which HMAC is used to compute the MACs of the channel
5616 * Added Hmac field to the Channel Message Payload. The integrity
5617 of plaintext channel messages are now protected by computing
5618 MAC of the message and attaching the MAC to the payload. The
5619 MAC is encrypted. Now, it is clear that this causes some
5620 overhead to the size of the packet but rationale for this is that
5621 now the receiver can verify whether the channel message decrypted
5622 correctly and also when private keys are set for the channel the
5623 receiver can decrypt the packet with several keys and check from
5624 the MAC which key decrypted the message correctly.
5626 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5627 lib/silccrypt/silccipher.[ch].
5629 * Added silc_hash_len to return the digest length into the
5630 lib/silcrypt/silchash.[ch].
5632 * Rewrote parts of Silc Channel Payload interface in the
5633 lib/silccore/silcchannel.[ch]. The encode function now also
5634 encrypts the packet and parse function decrypts it.
5636 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Fixed a minor formatting bug in the SKE's key material processing.
5639 It actually might have processed the keys wrong way resulting
5642 * Redefined the mandatory HMAC algorithms and added new algorithms.
5643 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5644 and hmac-md5 truncated to 96 bits. The mandatory is now
5645 hmac-sha1-96. Rest are optional (including the one that used
5646 to be mandatory). Rationale for this is that the truncated HMAC
5647 length is sufficient from security point of view and can actually
5648 make the attack against the HMAC harder. Also, the truncated
5649 HMAC causes less overhead to the packets. See the RFC2104 for
5652 * Added new [hmac] configuration section. The SKE used to use
5653 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5654 is of course wrong. The official names that must be proposed in
5655 the SKE are the ones defined in the protocol specification
5656 (hmac-sha1-96 for example). The user can configure any hmac
5657 using any hash function configured in the [hash] section. At
5658 least, the mandatory must be configured.
5660 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5662 * Added HMAC list to the SKE proposal list. It has now both
5663 hash algorithm list and HMAC list. This makes the protocol
5664 incompatible with previous versions. The SKE now seems to work
5665 the way it is supposed to work, for the first time actually.
5667 * Defined plain Hash algorithms to the protocol specification.
5670 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Implemented support for key agreement packets into the server.
5673 Added functions silc_server_key_agreement and
5674 silc_server_send_key_agreement. Other than these functions,
5675 server has nothing to do with this packet.
5677 * Added support for private message key packets into the server.
5678 Added functions silc_server_private_message_key and
5679 silc_server_send_private_message_key.
5683 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5684 called in the protocol's final callback instead in the END
5685 protocol state. This makes a little more sense and in the same
5686 time in client we can use the same protocol routines for normal
5687 key exchange and to key agreement packet handling as well.
5689 * Added to both client's and server's KE protocol context the
5690 SilcSKEKeyMaterial pointer to save the key material. We will
5691 bring the key material to the protocol's final callback by doing
5692 this. The final callback must free the key material.
5694 * Added SKE's packet_send callback into client's KE protocol
5695 context so that the caller can choose what packet sending function
5696 is used. This way we can use different packet sending when
5697 doing normal SKE when doing key agreement packet handling (in
5698 the key agreement packet handling we do not want to encrypt
5701 * Implemented the responder side of the key agreement routines
5702 in the client. The client can now bind to specified port and
5703 accept incoming key negotiation. The key material is passed
5704 to the application after the protocol is over.
5706 * Implemented the processing of incoming Key Agreement packet
5707 in the client. Added function silc_client_key_agreement to
5710 * Implemented the intiator side of the key agreement routines
5711 in the client. The client can now initiate key agreement with
5712 another remote client. The key material is passed to the
5713 application after the protocol is over.
5715 * Created client_keyagr.c to include all the key agreement
5718 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5719 SILC_TASK_CALLBACK except that it is not static.
5721 * Created client_notify.c and moved the Notify packet handling
5722 from the client.[ch] into that file.
5724 * Created client_prvmsg.c and moved all private message and
5725 private message key routines from the client.[ch] into that file.
5727 * Create client_channel.c and moved all channel message and
5728 channel private key routines from the client.[ch] into that file.
5730 * Changed silc_client_get_client_by_id_resolve to resolve with
5731 WHOIS command instead of IDENTIFY command, in the file
5732 lib/silclient/idlist.c.
5734 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Implemented the SKE's responder side to the Client library.
5738 * When FAILURE is received to the protocol do not trust it
5739 blindly. Register a timeout to wait whether the remote closes
5740 the connection as it should do it, only after that process the
5741 actual failure. This was changed to both client and server.
5743 * Added client_internal.h to include some of the structures
5744 there instead of client.h in lib/silcclient/.
5746 * Added function silc_task_unregister_by_callback to unregister
5747 timeouts by the callback function.
5749 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Some "Incomplete WHOIS info" errors has been appearing on the
5752 log files. Took away the entry->userinfo check from WHOIS
5753 reply sending. The entry->userinfo is now " " if client did not
5754 provide one. I thought this was fixed earlier but something
5755 is wrong still. Let's see if the error still appears.
5757 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Fixed a minor bug in the login when the channel key is
5760 re-generated in the server. It used to generate the key in
5761 wrong order and thus caused problems in the channel traffic.
5763 * Fixed a minor bug in channel key distsribution after
5764 KICK command. The key was not sent to the router even though
5767 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Added silc_ske_process_key_material_data as generic routine
5770 to process any key material as the SILC protocol dictates. The
5771 function is used by the actual SKE library but can be used by
5772 applications as well. This relates to the private message keys
5773 and the channel private keys since they must be processed the
5774 same way the normal SILC session keys. The protocol dictates
5775 this. Affected files: lib/silcske/silcske.[ch].
5777 Added also silc_ske_free_key_material to free the
5778 SilcSKEKeyMaterial structure.
5780 * Defined silc_cipher_set_key function to set the key for
5781 cipher without using the object's method function. The affected
5782 files: lib/silccrypt/silccipher.[ch].
5784 * Implemented silc silc_client_add_private_message_key,
5785 silc_client_add_private_message_key_ske,
5786 silc_client_del_private_message_key,
5787 silc_client_list_private_message_keys and
5788 silc_client_free_private_message_keys functions in the
5791 Added functions silc_client_send_private_message_key to send
5792 the Private Message Key payload and silc_client_private_message_key
5793 to handle incoming Private Message Key payload.
5795 * Added Cipher field to the Private Message Key payload to set
5796 the cipher to be used. If ignored, the default cipher defined
5797 in the SILC protocol (aes-256-cbc) is used.
5799 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Removed lib/silcclient/ops.h file.
5803 Redefined parts of the SILC Client Library API. Created new
5804 file silcapi.h that deprecates the ops.h file and defines the
5805 published Client Library API. Defined also private message key
5806 API and channel private key API into the file.
5808 This is the file that the application must include from the
5809 SILC Client Library. Other files need not be included by
5810 the application anymore.
5812 * Added new key_agreement client operation callback and also
5813 defined the Key Agreement library API for the application.
5815 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5818 is used by clients to request key negotiation between another
5819 client in the SILC network. If the negotiation is started it
5820 is performed using the SKE protocol. The result of the
5821 negotiation, the secret key material, can be used for example
5822 as private message key.
5824 Implemented the Key Agreement payload into the files
5825 lib/silccore/silauth.[ch].
5827 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Redefined ciphers for the SILC protocol. Added some new ciphers
5830 and defined the key lengths for the algorithms. Changed the
5831 code accordingly. The default key length is now 256 bits.
5833 * Fixed SKE key distribution function silc_ske_process_key_material
5834 when the key length is more than 128 bits. The default key
5835 length in SILC is now 256 bits.
5837 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5838 to indicate unsupported algorithm.
5840 * Renamed rijndael.c to aes.c and all functions as well.
5842 * Fixed a long standing channel key setting bug in client library.
5843 Weird that it has never surfaced before.
5845 * Fixed bug in channel deletion. If the entire channel is removed
5846 then it must also delete the references of the channel entry
5847 from the client's channel list as the client's channel entry and
5848 the channel's client entry share same memory.
5850 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Implemented CONNECT and SHUTDOWN commands in the client.
5854 * Implemented CLOSE command to the client.
5856 * Added the function silc_idlist_find_server_by_name into the
5857 files silcd/idlist.[ch].
5859 Added the function silc_idlist_find_server_by_conn into the
5860 files silcd/idlist.[ch].
5862 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * DIE command was renamed to SHUTDOWN. Updated the both code
5867 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5868 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5870 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5873 * Added function silc_server_create_connection function to create
5874 connection to remote router. My server implementation actually
5875 does not allow router to connect to normal server (it expects
5876 that normal server always initiates the connection to the router)
5877 so the CONNECT command is only good for connecting to another
5880 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5883 or some other client was kicked from the channel.
5885 Implemented the handling of the notify type to both client
5888 Implemented silc_server_send_notify_kicked to send the KICKED
5889 notify. It is used to send it to the server's primary router.
5891 * Implemented the KICK command into server and client.
5893 * Added `query' argument to the silc_idlist_get_client function
5894 to indicate whether to query the client from server or not if
5897 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5898 to indicate that the client is not channel founder.
5902 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Removed the rng context from SilcPacketContext structure and
5905 changed that the packet routine uses the Global RNG API.
5907 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Added support for quit message that client can "leave" on the
5910 channel when it quits the SILC. It is ditributed inside the
5911 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5913 Added silc_server_free_client_data that will take the
5914 signoff message as argument.
5916 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5918 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Updated parts of the protocol specification to keep it up
5923 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5926 payloads in one packet.
5928 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5929 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5930 use now the new List flag.
5932 * Also deprecated the following packet types: REPLACE_ID,
5933 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5935 * Added list support for Notify packet in server.
5937 * Added silc_server_send_notify_channel_change to send the
5938 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5939 the silc_server_send_replace_id.
5941 * Added silc_server_send_notify_nick_change to send the
5942 NICK_CHANGE notify type. Deprecates the function
5943 silc_server_send_replace_id.
5945 * Added silc_server_send_notify_join to send the JOIN notify type.
5946 Deprecates the function silc_server_send_new_channel_user.
5948 * Added silc_server_send_notify_leave to send LEAVE notify type.
5949 Deprecates the function silc_server_send_remove_channel_user.
5951 * Added silc_server_send_notify_cmode and
5952 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5953 types. Deprecates the silc_server_send_set_mode function.
5955 * Added SERVER_SIGNOFF notify type to indicate that server has
5956 quit. This means that all clients on the channel from that
5957 server will drop. This can be also used when netsplit happens.
5959 Deprecated REMOVE_ID packet type since it is not needed anymore
5962 Added silc_server_send_notify_server_signoff to send the
5963 SERVER_SIGNOFF notify type. Deprecates the function
5964 silc_server_send_remove_id.
5966 Added also silc_server_send_notify_signoff to send the
5967 SIGNOFF notify type.
5969 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5970 SILC protocol from this day on. Changed the protocol
5971 specification as well.
5973 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5974 notify type. It is used between routers to notify about
5975 topic changes on a channel.
5977 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5980 * Partly updated the protocol specification to comply with the
5981 changes now made. It is still though a bit outdated.
5983 * The JOIN notify type now takes one extra argument <Channel ID>.
5984 The packet used to be destined to the channel but now the
5985 JOIN type may be sent as list thus it is impossible to
5986 destine it to any specific channel. By adding this argument
5987 it is again possible.
5989 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Added CREDITS file. The CHANGES and CREDITS file will appear
5992 in the distribution as well.
5994 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5997 types in the server's silcd/packet_receive.c.
5999 * Implemented CMODE and CUMODE to work in router environment.
6001 * Fixed minor encoding and decoding buglet from the
6002 lib/silccore/silcmode.c.
6004 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6007 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6009 * Changed all SilcConfigServer* and silc_config_server* to
6010 SilcServerConfig* and silc_server_config*, respectively.
6013 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6015 * Associated the ID (client or server ID) to the Authentication
6016 Payload to avoid any possibility of forging. Updated the
6017 protocol specification and the code accordingly.
6019 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * The RSA key length is now save to the RsaKey context in the
6022 key generation process in lib/silccrypt/rsa.c. The key length
6023 is now used to figure out the maximum size of the block allowed
6024 to be encrypted/signed.
6026 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6027 is equivalent to the silc_mp_mp2bin but does not allocate any
6030 * Changed silc_mp_mp2bin API to take length argument. If it is
6031 non-zero then the buffer is allocated that large. If zero, then
6032 the size is approximated using silc_mp_sizeinbase, which however
6035 * Created Global RNG API which is global RNG that application can
6036 initialize. After initializing, any routine anywhere in the
6037 code (including library) can use RNG without allocating a new
6038 RNG object. This was done to allow this sort of use of the
6039 RNG in code that has no chance to allocate RNG object. All
6040 applications currently allocate this and many routines in the
6041 library use this. Affected file lib/silccrypt/silcrng.[ch].
6043 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6044 it to use the Global RNG API.
6046 * Defined Authentication Payload into protocol specification that
6047 is used during SILC session to authenticate entities. It is
6048 used for example by client to authenticate itself to the server
6049 to obtain server operator privileges.
6051 Implemented this payload into the lib/silccore/silcauth.[ch].
6052 Implemented also routines for public key based authentication
6053 as the new protocol specification dictates.
6055 Moved definitions of different authentication methods from
6056 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6058 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6059 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6060 silc_pkcs_verify_with_hash functions into the file
6061 lib/silccrypt/silcpkcs.[ch].
6063 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * The client entry's userinfo pointer must be always valid.
6066 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6067 will fail since it requires the userinfo. Now, the userinfo
6068 is allocated as "" if actual userinfo does not exist. Actually,
6069 it must exist and it is totally Ok to drop client connections
6070 that does not announce the userinfo. However, we will make
6071 this workaround for now.
6073 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6074 to return the remote port by socket.
6076 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6079 SILC_SERVER_PENDING_EXEC and added an new macro
6080 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6081 data or when error occurs while processing the pending command.
6083 Added new argument `destructor' into silc_server_command_pending
6084 and to the SilcServerCommandPending object. This destructor is
6085 now called after calling the pending callback or if error occurs
6086 immediately. If error occurs the actual pending callback won't
6087 be called at all - only the destructor. The destructor may be
6088 NULL if destructor is not needed.
6090 All this applies for client library code as well. Similar
6091 changes were made there as well for the pending commands.
6093 In the client, the application must now allocate the
6094 SilcClientCommandContext with the silc_client_command_alloc
6097 * Added reference counter to the SilcServerCommandContext. Added
6098 function silc_server_command_alloc and silc_server_command_dup
6101 Same type of functions added to the client library for the same
6104 * Removed the cmd_ident from IDListData away since it is now
6105 global for all connections. It is the command identifier used
6106 in command sending and with pending commands. The affected file
6109 * Added reference counter to the SilcSocketConnection objecet to
6110 indicate the usage count of the object. The object won't be
6111 freed untill the reference counter hits zero. Currently only
6112 server uses this, and client ignores it. The client must be
6113 set to use this too later. The affected files are
6114 lib/silccore/silcsockconn.[ch]. Added also the function
6115 silc_socket_dup to increase the reference counter.
6117 This was mainly added because it is possible that the socket
6118 is removed underneath of pending command or other async
6119 operation. Now it won't be free'd and proper DISCONNECTING
6120 flags, etc. can be set to avoid sending data to connection that
6121 is not valid anymore.
6123 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6124 the connection. After that it sets SILC_SET_DISCONNECTED.
6125 It is, however, possible that the socket data is not still freed.
6126 The silc_server_packet_process now checks that data is not
6127 read or written to connection that is DISCONNECTED. The socket
6128 get's freed when the reference counter hits zero.
6130 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Changed the client operation API: channel_message operation's
6133 `sender' is now the client entry of the sender, not the nickname
6134 and the `channel' is the channel entry, not the channel name.
6136 In the private_message operation the `sender' is now also the
6137 client entry of the sender not the nickname.
6139 Affected file is lib/silcclient/ops.h and all applications
6140 using the client operations.
6142 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Moved the calling of ops->connect() from connect_to_server_final
6145 into receive_new_id functin since that is the point when the
6146 client is actually allowed to send traffic to network. The
6147 affected file is lib/silcclient/client.c.
6149 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6152 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6153 (if needs broadcasting) instead of broadcasting the packets one
6154 by one which would make a burst in the network traffic.
6156 * Added `broadcast' argument to the functions in silcd/server.[ch]
6157 silc_server_create_new_channel[_with_id] to indicate whether
6158 to send New Channel packet to primary router.
6160 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Added new function into the silcd/server.[ch] files:
6163 silc_server_create_new_channel_with_id to create new channel with
6164 already existing Channel ID.
6166 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6167 lib/silccore/silcpacket.h. This packet is used t send list of
6168 Set Mode payloads inside one packet. Server uses this to set
6169 the modes for the channels and clients on those channels, that it
6170 announced to the router when it connected to it. The protocol
6171 specification has been updated accordingly.
6173 * The silc_server_new_channel did not handle the packet coming
6174 from normal server as it normally does not send that. However,
6175 when it announces its channels it does send it. Implemented
6176 the support for that.
6178 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6179 into the file lib/silccore/id.h.
6181 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Fixed memory leaks in the functions silc_idlist_del_client,
6184 silc_idlist_del_channel and silc_idlist_del_server in the file
6185 silcd/idlist.c. All of those leaked like a sieve.
6187 * Fixed some small memory leaks in the client's function
6188 silc_client_notify_by_server.
6190 * Added functions into silcd/server.c: silc_server_announce_clients,
6191 silc_server_announce_channels and silc_server_announce_server.
6192 These functions are used by normal and router server to announce
6193 to its primary router about clients, channels and servers (when
6194 router) that we own. This is done after we've connected to the
6197 These functions effectively implements the following packet types:
6198 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6199 and SILC_PACKET_NEW_ID_LIST.
6201 * Added new functions into the silcd/packet_receive.[ch]:
6202 silc_server_new_id_list, silc_server_new_channel_list and
6203 silc_server_new_channel_user_list to handle the incoming
6204 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6206 * Added support of changing Channel ID in the function
6207 silc_server_replace_id. If the server that announces a channel
6208 to the router already exists in the router (with same name but
6209 with different Channel ID), router is responsible to send
6210 Replace ID packet to the server and force the server to change
6211 the Channel ID to the one router has.
6213 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6214 client that the Channel ID has been changed by the router. The
6215 normal server sends this to the client. Client must start using
6216 the new Channel ID as the channel's ID.
6218 Implemented handling of this new type into lib/silcclient/client.c
6219 into the function silc_client_notify_by_server.
6221 * Added new function silc_idlist_replace_channel_id into the files
6222 silcd/idlist.[ch] to replace the Channel ID.
6224 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Call silc_server_command_identify_check always when processing
6227 the IDENTIFY command in silcd/command.c
6229 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6232 send keepalive packets. The packet can be sent by clients,
6233 servers and routers.
6235 Added function silc_socket_set_heartbeat into the file
6236 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6237 If not set, the heartbeat is not performed. The actual
6238 heartbeat is implemented in the low level socket connection
6239 library. However, application is responsible of actually
6242 Added silc_server_send_heartbeat to send the actual heartbeat
6243 packet into silcd/packet_send.[ch]. Server now performs
6244 keepalive with all connections.
6246 * Added silc_task_get_first function into lib/silcutil/silctask.c
6247 to return the timeout task with shortest timeout. There was a bug
6248 in task unregistration that caused problems. TODO has been
6249 updated to include that task system must be rewritten.
6251 * The client library will now resolve the client information when
6252 receiving JOIN notify from server for client that we know but
6253 have incomplete information.
6255 * Rewrote parts of silc_server_remove_from_channels and
6256 silc_server_remove_from_one_channel as they did not remove the
6257 channel in some circumstances even though they should've.
6259 * Encryption problem encountered in server:
6261 The LEAVE command used to send the Channel Key packet to the
6262 router immediately after generating it. However, the code
6263 had earlier sent Remove Channel user packet but not immediately,
6264 ie. it was put to queue. The order of packets in the router
6265 was that Channel Key packet was first and Remove Channel User
6266 packet was second, even though they were encrypted in the
6267 reverse order. For this reason, MAC check failed. Now, this
6268 is fixed by not sending the Channel Key packet immediately but
6269 putting it to queue. However, this is more fundamental problem:
6270 packets that are in queue should actually not be encrypted
6271 because packets that are sent immediately gets encrypted
6272 actually with wrong IV (and thus MAC check fails). So, packets
6273 that are in queue should be encrypted when they are sent to
6274 the wire and not when they put to the queue.
6276 However, the problem is that the current system has not been
6277 designed to work that way. Instead, the packet is encrypted
6278 as soon as possible and left to the queue. The queue is then
6279 just purged into wire. There won't be any fixes for this
6280 any time soon. So, the current semantic for packet sending
6283 o If you send packet to remote host and do not force the send
6284 (the packet will be in queue) then all subsequent packets to the
6285 same remote host must also be put to the queue. Only after the
6286 queue has been purged is it safe again to force the packet
6289 o If you send all packets immediately then it safe to send
6290 any of subsequent packets through the queue, however, after
6291 the first packet is put to queue then any subsequent packets
6292 must also be put to the queue.
6294 Follow these rules and everything works fine.
6296 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added new function silc_server_remove_clients_by_server to
6299 remove all client entries from ID list when the server connection
6300 is lost. In this case it is also important to invalidate all
6301 client entires as they hold the invalid server entry. This
6302 fixes fatal bug when server has lost connection and will reconnect
6305 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Made some sanity checks to silc_server_daemonise like to check
6308 whether the requested user and group actually exists.
6310 * Added sanity check to SKE's silc_ske_responder_finish to check
6311 that the public and private key actually is valid.
6313 * Invalidate the client's nickname when receiving Replace ID
6314 packet and the Client ID is being replaced. This means that the
6315 server will query the nickname if someone needs it (client)
6318 * Sort the ID Cache in client library when the ID Cache data
6319 has changed (needs sorting).
6321 * Do not allow for SILC client to create several connections to
6322 several servers. The client does not support windows right now
6323 and generating multiple connections causes weird behaviour.
6325 Irssi-silc client does support windows and can handle several
6326 connections without problems, see: www.irssi.org and SILC plugin.
6328 * Fixed some places where client was added to the IDList. The
6329 rule of thumb is following (in order to get everything right):
6330 If the client is directly connected local client then the
6331 `connection' argument must be set and `router' argument must be
6332 NULL to silc_idlist_add_client function. If the client is not
6333 directly connected client then the `router' argument must
6334 bet set and the `connection' argument must be NULL to the
6335 silc_idlist_add_client function.
6337 * The funtion silc_server_packet_send_local_channel actually did
6338 not check whether the client was locally connected or not. It
6339 does that now. Fixed a bug related to LEAVE command.
6341 * Fixed Remove Channel User payload parsing bug in server's
6342 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6344 * The server's silc_server_save_channel_key now checks also the
6345 global ID list for the channel as it might not be in the local
6346 list. Fixed a bug related to LEAVE command.
6348 * Is this the end of the [<unknown>] buglet that has been lurking
6349 around for a long time? A little for loop fix in server's
6350 silc_server_command_whois_parse that is used by both IDENTIFY
6351 and WHOIS command. At least, this was a clear bug and a cause
6352 of one type of [<unknown>] buglet.
6354 * WHOIS and IDENTIFY commands call the function
6355 silc_server_command_[whois/identify]_check function even if
6356 we are not router server.
6358 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Added --with-gmp configuration option. If set the GMP
6361 is always compiled in the SILC source tree. If not set then
6362 it is checked whether the system has the GMP3 installed. If
6363 it has then the GMP won't be compiled (the system's headers
6364 and library is used), if it doesn't have it then the GMP is
6365 compiled in the SILC source tree.
6367 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Changed RSA private exponent generation to what PKCS #1
6370 suggests. We try to find the smallest possible d by doing
6371 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6372 not security fix but optimization.
6374 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Added new config entry [Identity] to fork the server and run
6377 it as specific user and group. A patch from Bostik.
6379 * Imported Dotconf configuration library into lib/dotconf.
6380 This will be used to create the SILC configuration files later.
6381 It will appear in the distsribution after this commit.
6383 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * A big code auditing weekend happening. Auditing code for
6386 obvious mistakes, bugs and errors. Also, removing any code
6389 Removed files for being obsolete:
6391 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6392 inline in the file lib/silcutil/silcbuffer.h)
6394 o lib/silcutil/silcbufutil.c (the header has inline versions)
6396 Changed code to fix possible error conditions:
6398 o The buffer formatting routines now check that the destination
6399 buffer really has enough space to add the data. This applies for
6400 both buffer formatting and unformatting
6401 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6402 unformatting was changed to accomodate following rules:
6403 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6404 sent to the function while XXX_*STRING will not allocate or copy
6405 the data into the buffer. Instead it sets the pointer from the
6406 buffer into the pointer sent as argument (XXX_*STRING used to
6407 require that the pointer must be allocated already). This change
6408 makes this whole thing a bit more consistent and more optimized
6409 (note that the data returned in the unformatting with XXX_*STRING
6410 must not be freed now). The routines return now -1 on error.
6412 o Tried to find all code that use buffer_format and buffer_unformat
6413 and added return value checking to prevent formatting and
6414 especially unformatting errors and possible subsequent fatal
6417 o Changed ske->x and ske->KEY to mallocated pointers in
6418 lib/silcske/silcske.h. Fixed possible data and memory leak.
6420 o Added return value checking to all *_parse* functions. Fixed
6421 many memory leaks as well.
6423 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6424 so that buffer overflows would not happen. All code now also
6425 checks the return value as it can fail.
6427 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Added reconnection support to server if the normal server looses
6430 its connection to the router (for example if router is rebooted).
6431 The server performs normal reconnection strategy implemented
6432 to the server. Affected file silcd/server.c.
6434 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Added new packet type SILC_PACKET_SET_MODE that is used to
6437 distribute the information about changed modes (for clients,
6438 channels and clients channel modes) to all routers in the
6439 network. Updated the protocol specification accordingly.
6441 Added functions into silcd/packet_send.c and
6442 silcd/packet_receive.c: silc_server_send_set_mode,
6443 silc_server_set_mode.
6445 Added new files silcmode.[ch] into lib/silccore that implements
6446 the encoding and decoding of Set Mode Payload. Added new type
6447 SilcSetModePayload. Moved the definitions of different modes
6448 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6450 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Oops, a little mistake in server's connection authentication
6453 protocol. The protocol is not ended with FAILURE but with
6454 SUCCESS if the authentication is Ok. :) Affected file is
6457 * Implemented NICK_CHANGE notify handling in server in the file
6458 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6459 the local clients on the channel. After the changing nickname
6460 in router environment snhould work and the [<unknown>] nickname
6461 should appear no more.
6463 The silc_server_replace_id function that receives the Replace ID
6464 payload now sends the NICK_CHANGE notify type also in the file
6465 silcd/packet_receive.c
6467 * Changed WHOIS and IDENTIFY command to support the maximum amount
6468 of arguments defined in protocol specs (3328 arguments). This
6469 fixed a bug that caused problems when there were more than three
6472 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Added extra parameter, command identifier, to the
6475 silc_client_send_command so that explicit command identifier
6478 Changed that ID list routines uses specific command identifier
6479 when sending WHOIS/IDENTIFY requests to the server so that they
6480 can be identified when the reply comes back.
6482 Affected files lib/silcclient/command.[ch],
6483 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6485 * Added `sender' argument to silc_server_packet_send_to_channel
6486 to indicaet the sender who originally sent the packet to us
6487 that we are now re-sending. Ignored if NULL. Affected file
6488 silcd/packet_send.[ch].
6490 * Added some server statistics support in silcd/server_internal.h
6491 SilcServerStatistics structure and around the server code. Also
6492 send some nice statistics information when client is connecting
6495 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Fixed channel ID decoding in server's JOIN command reply in
6498 silcd/command_reply.c
6500 * Fixed braodcasting of replace ID payload to not to send it if
6501 we are standalone server in silcd/packet_receive.c.
6503 * Fixed all channel message sending routines to not to send
6504 packets to clients that has router set, since they are routed
6505 separately in the same function earlier. Affects file
6506 silcd/packet_send.c and all channel packet sending functions.
6508 * In USERS reply, res_argv[i] are not allocated, the table
6509 is allocated. Thus changed that free the table, not its
6512 * In server's whois_check and identify_check if the client is
6513 locally connected do not send any WHOIS commands - they are not
6516 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Fixed some minor bugs in client when sending WHOIS command. The
6519 arguments was in wrong order.
6521 * Removed statis function add_to_channel from server in
6522 silcd/command.c that was previously used with the joining but
6525 * Tested USERS command in router environment successfully with two
6526 routers, two servers and two clients.
6528 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Reorganized the USERS command and command reply in client library
6531 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6532 When the command is given by user we register a pending command
6533 callback that will reprocess the command after the reply has been
6534 received from the server. When reprocessing the packet we then
6535 display the information. Thus, the USERS information is displayed
6536 now in the command callback instead of in the command reply
6537 callback. The processing of the command is same as previously
6538 when server has sent the command reply in the JOINing process.
6540 * Added to USERS command in silcd/command_reply.c to join the client,
6541 we didn't use to know about, to the channel after we've created
6542 a client entry for it. Also, for clienet we did know already still
6543 check whether it is on the channel or not and add it if not.
6545 * Removed silc_server_command_join_notify as the function and its
6548 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Changed the client's pending command handling to the same as the
6551 server's pending command handling. It is also now possible to
6552 execute command reply functions from other command reply
6553 function as the function callbacks for commands and command
6554 replies are one and same. The pending commands are not static
6555 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6556 in client connection context. Thus, pending commands are server
6557 connection specific as it is convenient.
6559 Changed the function silc_client_command_pending and
6560 silc_client_command_pending_del and added new function
6561 silc_client_command_pending_check. Removed the
6562 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6565 * Added cmd_ident, current command identifier, to the client
6566 connection context in lib/silcclient/client.h to keep track on
6567 command identifiers used in command sending. Client's command reply
6568 function handling now supports the mandatory command identifiers.
6570 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6571 funtions in client to fully support pending command callbacks.
6573 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6574 as one of the arguments to the application in the command reply
6577 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6578 before first releasing SILC but came back. Now it is removed again
6579 and should come back nomore. The FORWARDED flag was used only
6580 by the JOINing procedure by forwarding the command packet to router.
6581 Now, the JOINing procedure has been changed to more generic (due
6582 to various router environment issues) and FORWARDED is not needed
6583 anymore for anything. The protocol specification is yet to be
6586 Now, removed silc_server_packet_forward from server and the flag
6587 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6589 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Renamed NAMES command to USERS command. The NAMES was named that
6592 due to historical reasons. Now it is renamed. Also, rewrote
6593 parts of the USERS command. The nickname list is not sent anymore
6594 by the server. Only Client ID and mode lists are sent in the USERS
6595 command. Changed this also to the protocol specification.
6597 The client now resolves the names and stuff after it receives
6598 the USERS list from the server when joining to the channel.
6600 * WHOIS and IDENTIFY commands has been changed to support multiple
6601 Client ID's per command. One can now search for multiple users
6602 in the network by sending only one WHOIS or IDENTIFY command.
6603 Changed the code and the protocol specifications.
6605 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6606 uses silc_server_command_whois_parse to parse the request. */
6608 * If normal server, do not parse the WHOIS and IDENTIFY requests
6609 before sending it to the router. Saves some time.
6611 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * Fixed JOIN command on client library. Wrong number of arguments
6614 used to crash the client.
6616 * Added silc_server_channel_has_global function to check whether
6617 channel has global users or not.
6619 * Added silc_server_channel_has_local function to check whether channel
6620 has locally connected clients on the channel.
6622 * The silc_server_remove_from_one_channel now checks whether the
6623 channel has global users or not after given client was removed from
6624 the channel. It also checks whether the channel has local clients
6625 on the channel anymore. If it does not have then the channel entry
6626 is removed as it is not needed anymore.
6628 * The silc_server_notify now checks on JOIN notify whether the joining
6629 client is one of locally connected or global. If it is global then
6630 the channel has now global users on the channel and that is marked
6631 to the channel entry. Also, it now saves the global client to
6632 global list who is joining and JOINs it to the channel. This is
6633 for normal server, that is.
6635 Changed silc_server_send_notify_on_channel,
6636 silc_server_packet_relay_to_channel and
6637 silc_server_packet_send_to_channel check if we are normal server
6638 and client has router set (ie. global client) do not send the
6639 message to that client, as it is already routed to our router.
6641 * Implemented LEAVE notify type handling in silc_server_notify
6644 * Tested LEAVE command in router environment successfully. Tested
6645 with two routers, two servers and two clients.
6649 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6651 * Implemented SIGNOFF notify type handling in silc_server_notify
6654 * silc_server_remove_id now removes the client entry from all channels
6655 it has joined and thusly sends SIGNOFF notify type.
6657 * Rewrote the NAMES list generation in server by removing two excess
6658 loops. The lists are created now inside one loop.
6660 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * silc_server_remove_channel_user checks now also global list
6663 for channel and client.
6665 * silc_server_new_channel_user checks now both local and global
6666 list for channel and client. Fixed a bug in client id decoding.
6667 Used to decode wrong buffer.
6669 * silc_server_channel_message checks now both local and global
6670 list for channel entry.
6672 * Tested channel joining (hence JOIN) in router environment
6673 successfully. Tested with two routers, two servers and two
6676 * Tested channel message sending in router environment successfully.
6678 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Added silc_server_save_channel_key into server.[ch] to save the
6681 received channel key in Channel Key payload processing. It is
6682 also used in JOIN command reply handling.
6684 Equivalent function silc_client_save_channel_key added into
6685 client.[ch] into client library.
6687 * Changed JOIN command reply to send information whether the channel
6688 was created or not (is existing already) and the channel key
6689 payload. Changed protocol specs accordingly.
6691 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6692 the request was sent by ID and not by nickname. Crashed on
6695 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6698 now correctly save the received data.
6700 * silc_server_free_sock_user_data now notifies routers in the
6701 network about entities leaving the network.
6703 At the same time implemented functions silc_server_remove_id
6704 and silc_server_send_remove_id to receive and send REMOVE_ID
6705 packets. The packet is used to notify routers in the network
6706 about leaving entities. The ID removed will become invalid in
6709 * Added function silc_idlist_del_server into server. Removes and
6710 free's server entry from ID list.
6712 * silc_server_private_message function now checks, if we are router,
6713 that the destination ID really is valid ID, naturally.
6715 * In router when NEW_ID packet is received (for new client) the
6716 hash of the Client ID is saved in the ID Cache but the
6717 client->nickname is set to NULL, instead of putting the hash
6720 IDENTIFY command now also checks that client->nickname must be
6721 valid. If it is not if will request the data from the server who
6722 owns the client. Added new function
6723 silc_server_command_identify_check.
6725 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6726 to set the command to already allocated Command Payload.
6728 * Tested private message sending in router environment with two
6729 routers, two servers and two clients. Fixed minor bugs and now
6732 * Fixed segfault from client's NAMES command. Used to crash if
6735 * Forwarded packets must not be routed even if it is not destined
6736 to the receiver. Changed server code comply with this.
6738 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Added `require_reverse_mapping' boolean value to ServerParams
6741 structure. If TRUE (not default) the server will require that
6742 the connecting host has fully qualified domain name.
6744 If the reverse mapping is not required and hostname could not be
6745 found the IP address is used as hostname.
6747 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Implemented version string checking to both client and server.
6750 The check is incomplete currently due to the abnormal version
6751 strings used in development version of SILC.
6753 * Changed all command functions in server to use the new
6756 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Changed char *data to unsigned char *data in ID Cache system to
6759 support binary data as ID Cache data. Changed code to support
6760 binary data in lib/silccore/idcache.c.
6762 * Renamed silc_server_packet_relay_command_reply to
6763 silc_server_command_reply as it is normal packet receiving
6764 function. Rewrote the function to accept command replys for
6765 servers and not only for clients.
6767 * Mark remote router always as registered server if we are connecting
6768 to it. Otherwise, commands sent by the router to us are ignored.
6770 * All ID List find routines now returns the ID Cache Entry pointer
6771 as well if requested.
6773 * WHOIS command works now in router environment, tested with two
6774 routers, two servers and two clients.
6776 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6777 in router environment (as it is almost equivalent to WHOIS) but
6778 hasn't been tested thoroughly. Added new functions:
6780 silc_server_command_identify_parse
6781 silc_server_command_identify_send_reply
6782 silc_server_command_identify_from_client
6783 silc_server_command_identify_from_server
6785 * Disabled route cache adding because adding two different ID's with
6786 same IP replaces the old cache entry thus giving wrong route.
6787 The entry->router->connection is always the fastest route anyway
6788 so route cache may not be needed. Of course, new routes maybe
6789 established after receiving the ID when the entry->router->connection
6790 might not be anymore the most optimal.
6792 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Add route cache for received ID for fast routing.
6796 * Added silc_server_packet_route to route received packet on router
6797 that is not destined to us.
6799 * Renamed silc_server_get_route to silc_server_route_get.
6801 * Added id_string and id_string_len fields into SilcServer to
6802 include encoded ServerID for fast comparing without excess
6803 encoding of the ID's.
6805 * Cleaned up WHOIS command on server side. Added following static
6808 silc_server_command_whois_parse
6809 silc_server_command_whois_check
6810 silc_server_command_whois_send_reply
6811 silc_server_command_whois_from_client
6812 silc_server_command_whois_from_server
6814 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6815 arguments in command replies. All command functions should be
6816 updated to use this macro.
6818 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Minor typo fixes on command reply handling on server.
6822 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * Added silc_server_command_add_to_channel internal routine to add
6825 the client to the channel after router has created the channel and
6826 sent command reply to the server.
6828 * Added generic silc_server_send_command to send any command from
6831 * Use static buffer with ID rendering instead of duplicating data.
6833 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Fixed a channel user mode bug when joining to a channel server gave
6836 everybody channel founder rights, oops.
6838 * We mark ourselves as the router of the incoming server connection
6839 if we are router ourselves. This way we can check in some packet
6840 sending functions whether it is locally connected server. For
6841 incoming router connections we put NULL.
6843 * For router sending packets locally means now always sending the
6844 packet cell wide; to local clients and local servers. For normal
6845 server sending packet locally means sending it to only local
6848 * Fixed the JOIN command to really work in router environment. If the
6849 channel is created it is always created by the router. Router is
6850 also responsible of making the initial joining to the channel,
6851 sending JOIN notify to the sending server and distributing
6852 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6853 does not exist server doesn't do anything else but forward the
6854 command to the router which performs everything.
6856 * Added silc_server_send_channel_key function to send the Channel Key
6859 * Added silc_server_create_channel_key to create new channel key. The
6860 channel key is now re-generated everytime someone joins or leaves
6861 a channel, as protocol dictates. Note: channel->key_len is the
6864 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6867 packet_receive.[ch] to separate packet sending and receiving
6868 routines. The server.[ch] now includes everything else including
6869 actual packet processing (writing and reading data) and other
6872 Renamed silc_server_private_message_send_internal to
6873 silc_server_send_private_message. The routine is still though
6874 used only to relay private messages as server does not send
6875 private messages itself.
6877 Renamed silc_server_new_channel to silc_server_create_new_channel
6878 and added new function sicl_server_new_channel that handles the
6879 incoming New Channel packet. Added also new sending function
6880 silc_server_send_new_channel to send New Channel Payload.
6882 * Added new function silc_server_notify to process incoming notify
6883 packet to the server/router. Server may then relay the notify
6884 to clients if needed.
6886 * Added new function silc_server_new_channel_user to process incoming
6887 New Channel User packet. Router will redistribute the packet and
6888 send JOIN notify to its local clients and locally connected servers
6889 if needed. Normal server will send JOIN notify to its local client
6890 on same channel when received this packet. Added also corresponding
6891 sending function silc_server_send_new_channel_user to sent the
6894 * Added boolean route argument to send_notif_to_channel and
6895 packet_send_to_channel functions to attempt to route the packet
6896 if it is TRUE and send only locally if it is FALSE.
6898 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * silc_server_replace_id now broadcasts the received replace ID
6901 packet if it is not broadcast packet already. The router must
6902 broadcast to inform other routers about changed ID.
6904 * Added backpointer to server's router into SilcServer context in
6905 silcd/server_internal.h.
6907 * Fixed silc_server_packet_broadcast to send correct broadcast
6910 * The channel key is now distributed to the local client as soon
6911 as it is received from the router (in router environment) so that
6912 no other packet may be sent for the channel until client has
6915 * silc_server_remove_channel_user now broadcasts the received
6916 Remove Channel User packet if it is not broadcast packet already.
6917 The router must broadcast to inform other routers about removed
6920 * Added users field into SilcPacketContext that is a reference count
6921 of the context. One can increase the reference count by calling
6922 silc_packet_context_dup which is now changed to just increase the
6923 reference count instead of duplicating the data. The reference
6924 count is decresed by calling silc_packet_context_free that will
6925 free the data after the reference count hits zero.
6927 For now on the packet context and everything allocated into it
6928 (including the raw packet from network) must be freed by calling
6929 the new silc_packet_context_free function. Added also new function
6930 silc_packet_context_alloc that must be used now to allocate the
6931 context. This also means that if a routine is asynchronous from
6932 silc_[client/server]_packet_parse_type the packet context must
6933 be duplicated by calling silc_packet_context_dup. Otherwise it
6934 gets free'd after silc_[client/server]_packet_parse_type returns.
6935 Also, one must remember that if packet is duplicated then its
6936 reference count must be decresed by calling the free function as
6937 many times as it was duplicated.
6939 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6940 from both client and server.
6942 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6944 * Made joining to a channel working in router environment.
6946 * Cleaned up JOIN command on server side and create function
6947 silc_server_command_join_channel internal routine to make the
6950 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Changed silc_command_pending list to SilcDList. Also, added
6953 `ident' field to SilcServerCommandPending structure to identify
6954 the reply and to call correct callback.
6956 Added silc_server_command_pending_check function to replace the
6957 corresnponding macro. The silc_command_pending list is not
6960 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6961 to set identifier to previously allocated Command Payload. It
6962 is used to set identifier for command when resending Command
6965 * Added silc_command_payload_encode_payload to encode Command
6966 Payload buffer from SilcCommandPayload structure.
6968 * Added silc_argument_payload_encode_payload to encode Argument
6969 payload buffer from SilcArgumentPayload structure.
6971 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Changed WHOIS command to support router connection on server side.
6974 The whois request is always sent to router unless the server is
6975 standalone server. After server has received the reply from the
6976 router will it send the reply to the client.
6978 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6979 broadcast received broadcast packet. The function is used only
6980 by router. The broadcast packet is always sent to the router's
6983 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6984 render given ID to printable string, for log files for example.
6986 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Made basic router to router connections working. At least they
6989 can now connect to each other but nothing really works the way
6990 they are supposed - yet.
6992 * Added new initiator token to RouterConnection configuration
6993 file in silcd/serverconfig.[ch]. It is used to tell whether we
6994 are the initiator to the remote router or whether we'll expect
6995 the other end to connect.
6997 * Moved registering of listener task to silc_server_init, hence
6998 the server starts listenning as soon as it is run, even if it
6999 does not have connections to other routers. Let's see how well
7002 * Changed default connection retry timeouts for more suitable in
7005 * Removed cipher and such arguments from silc_idlist_add_client
7006 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7007 Added new function silc_idlist_add_data to add the keys and stuff
7010 * Added SilcIDListData structure and added it to SilcClientEntry
7011 and SilcServerEntry as their first field in the structure. This
7012 way we can explicitly cast the ID entries to the SilcIDListData
7013 structure and get common data for the entries. In past, we had
7014 to first check what type of connection it is and then cast it to
7015 correct ID entry type. Now, we can directly cast the opaque
7016 pointer to the SilcIDListData (no matter what ID entry it actually
7017 is) and get the data needed.
7019 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7021 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7022 in some circumstances even if threre were timeout tasks, though not
7023 IO tasks, but tasks anyway. Now fixed.
7025 * Defined SilcServerConnection structure to hold connection specific
7026 stuff about directly connected servers and routers. The definition
7027 is currently in silcd/server_internal.h. I thought about having
7028 a bit more important role fro this struct but for now it is used
7029 only when connecting to other server (or router actually).
7031 * Added connecting retry support in server when connecting to
7032 router(s). The retry feature implement exponential backoff
7033 algorithm. Also, added SilcServerParams structure to hold default
7034 parameters for server. For now, it include these retry settings
7035 and are hard coded. After server is moded to be as Silc Server
7036 Library this structure will be more important.
7038 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Changed client librarys channel->clients table to SilcList and
7041 changed code accordingly.
7043 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Changed client's channel table to SilcList and changed code
7046 accordingly. Also changed SilcChannelClientEntry to include back-
7047 pointer to the channel so that client entry can use that structure
7048 as list as well and we have fast cross-reference to the channel.
7049 This change dramatically decreased the complexity of channel
7050 handling with client entry and vice versa (removed one extra
7051 loop when searching for channel entry from many functions).
7053 * Changed server->sim from table to SilcDList and changed code
7056 * NAMES command can now be used from user interface. It will show
7057 the user list on the channel, neatly.
7059 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7060 Code now saves realname of the user if it becomes available.
7062 * Renamed configure.in to configure.in.pre and made ./prepare
7063 script to automatically add correct version string to
7064 configure.in which it creates from configure.in.pre.
7066 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * NAMES command reply now shows users mode with the nickname when
7071 * Moved silc_client_ch[u]mode[_char] functions from
7072 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7073 place sucks, they are utility functions and should be in some
7076 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7078 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7081 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Added TRQ (efficient deque and list library) into lib/trq. This is
7086 a very good list library that is currently used in the SILC. Defined
7087 SilcList API over the library because I didn't like the API very
7088 much. See lib/trq/silclist.h for the API and examples of how to
7089 use the API. Fixed various places in the code to use the new
7090 SilcList API. The SilcList is meant for lists that has a structure
7091 already defined as a list. It is not suitable to add just some
7092 context to the list (in TRQ, the context is the list actually).
7094 So, I defined SilcDList that can be used for the purpose where
7095 predefined list structure does not exit. This can be used as
7096 such list. Now some context just can be added to the SilcDList.
7097 Currently this list is not used in the SILC just yet, though there
7098 are a lot places where this can replace dynamically allocated
7099 tables and I will fix these places, later, to use SilcDList.
7100 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7101 and use TRQ internally).
7103 Also fixed some annoying warning messages that the original TRQ
7104 code generated. Also minor changes to TRQ's Makefile.in.
7106 * Added support for querying by Client ID to both WHOIS and
7107 IDENTIFY commands into server, as required by the protocol.
7109 * Removed method function pointers from SilcBuffer structure. They
7110 weren't used to anything and just increased the context size for
7111 no good reason. This change also made silc_buffer_alloc and
7112 silc_buffer_free functions inline functions.
7114 * Disabled command flooding detection support until it's fixed so
7115 that it accepts commands in but does not execute them more than once
7118 * Added silc_net_localhost(), to return local hostname, into
7119 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7120 that must be initialized before calling silc_client_init.
7122 * Added new function: silc_server_send_notify_on_channels to send
7123 notify messages to all channels client has joined. It is assured
7124 that the message is sent only once per client.
7126 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7127 lib/silcutil/silcutil.[ch] as silc_format function. The new
7128 function is generic and is used by server as well, not only by
7129 the logging routines.
7131 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7132 the provided version string was not acceptable. Added new function:
7133 silc_ske_check_version into lib/silcske/silcske.h. The function
7134 must be implemented by the application (client or server) and it
7135 does not reside in the SKE library. The function checks the version
7136 string remote end sent.
7138 * Added back pointers (to opaque context and to SilcSocketConnection)
7139 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7141 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7142 duplicate packet context structure.
7144 * Changed `notify' client operation to send same arguments as client
7145 receives from server except for ID's. ID's are mapped to correct
7146 ID entry and that is returned. Also, if channel entry is not sent
7147 by server but the notify is for channel the channel entry is sent
7148 to application (otherwise application doesn't know that it is for
7149 channel (library gets it from packet's Destination ID)).
7151 * Added silc_client_remove_from_channels into client library to
7152 remove a client from all channels it has joined to. Used when
7153 received SIGNOFF notify from server. Added also new function
7154 silc_client_replace_from_channels to replace old ID entry with
7155 new ID entry on all channels. Used when received NICK_CHANGE
7158 * Fixed ID Cache list handling in silc_idlist_get_client in
7159 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7160 to get (or query) client by ID.
7162 * Updated TODO list.
7164 * Added connection authentication status message defined by the
7165 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7166 support for these into the code in client and server side.
7168 * Added generic function silc_client_send_command to send any command
7169 with variable argument list. Application should use this function
7170 to send commands if the command functions provided by the library
7171 does not suite for the application's user interface needs.
7173 * Added new `failure' client operation. Application is notified about
7174 received failure packet if client is executing a protocol. In this
7175 case the protocol's execution has failed.
7177 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7178 is required by the protocol.
7180 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7181 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7184 * Added status flag to SilcSKE object to indicate realtime status
7185 of the SKE protocol.
7187 * Application receives now exactly same command reply arguments as
7188 the library receives from server. However, if ID is received the
7189 corresponding ID entry is returned to the application (eg. Client
7190 ID is mapped to correct SilcClientEntry entry and that is returned).
7191 Changed command_reply client operation due to this change.
7193 * Changed all ID's in commands and in command replys as ID Payloads.
7194 Change affected both client and server side codes.
7196 All ID's sent in SILC network (with execption of ID's in SILC
7197 Packet header) are sent in ID Payload to support variable length
7200 * Server now notifies nick changes and notifies all clients on
7201 the channels about the new nickname (about the new Client ID,
7204 * Implemented CMODE command to change channel modes. Supports all
7205 channel modes defined by the protocol specs except ban and invite
7206 lists. (Also, private channel key mode is supported but support for
7207 setting private channel key in client is missing, thus, this mode
7208 has no effect on client side (except that server requires that the
7209 client uses private channel key and normal channel traffic does not
7212 Also, invite mode works per se, but INVITE command does not work
7213 yet correctly, so you can set channel as invite only channel but
7214 inviting clients to the channel does not work (it is yet to be
7215 thought what's the best way to do it).
7217 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7218 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7219 Implemented CUMODE command to change user's mode on the channel.
7220 Supports all modes defined by the protocol specs.
7222 * Added NAMES command reply to return users modes on the channel.
7224 * Removed unnecessary and slow ciphers from lib/silccrypt.
7226 * Set SO_KEEPALIVE option to connection sockets by default.
7228 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7230 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7231 redefined the Notify Payload into protocol specs.
7233 * Added silc_id_payload_parse_id to get ID directly from raw
7236 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7239 accept searching by Client ID as well.
7241 * Added support for LEAVE and SIGNOFF notify types in client library.
7243 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7244 to parse ID Payload from raw data.
7246 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7248 * Added flags parameter into silc_ske_assemble_security_properties
7249 function in lib/silcske/silcske.[ch].
7251 * Changed notify client operation to fit better for notify messages
7252 sent by server. The notify payload received from server is now
7253 passed to the application (after parsing it to SilcNotifyPayload).
7254 It is application's responsibility to retrieve the arguments
7255 from the payload and show the message the way it wants. The message
7256 sent by server is implementation specific.
7258 * Changed public keys to comply with the protocol specification.
7259 Old public keys are not supported anymore and are not compatible.
7261 * Removed nickname from Channel Payload as the latest draft removed
7262 it. The client must resolve the nickname from the NAMES command
7263 reply received when it joined the channel.
7265 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7267 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Fixed some errors in protocol specification drafts.
7271 * Created lib/silccore/silcnotify.c to implement Notify Payload
7272 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7273 generic payloads described by protocol specifications. The file
7274 includes implementations for ID Payload and Argument Payload.
7276 * Changed Command Payload implementation to use the new Argument
7277 Payload. Changed command_xxxx_payload to command_payload_xxxx
7278 to comply with SILC coding conventions.
7280 * Added suppport for Argument Payload handling in Notify Payload
7281 implementation as protocol requires it. Added the new support
7282 into server and client lib as well.
7284 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7286 * Added support for multiple nicknames on same channel. [n] is
7287 added locally to the nickname if there are more than one same
7288 nicknames on the channel.
7290 * Server now sends all nicknames that matched WHOIS request.
7291 Client also shows the list received from server.
7293 * Added TOPIC command to client side. User can now set and show
7294 current topic on channel.
7296 * Added MOTD command to client and server. Also, server sends the
7297 motd when client connects to the server.
7299 * Changed version strings to comply ISO 8601.
7301 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7303 * Fixed protocol error handling in client library. It should now
7304 cope even if the SKE fails for some reason.
7306 * Made new protocol specification drafts for submitting to IETF.
7308 * Implemented TOPIC command to server in silcd/command.c.
7310 * Added two new notify types into lib/silccore/silcnotify.h:
7311 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7312 notify nickname change and topic setting/change on a channel.
7314 * API change of command_reply operation in client library. The
7315 application gets now the status type received from server as well.
7317 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7321 * Cras fixed and optimized the packet handling even further and
7322 it should work now. Minor change to the prototype of function
7323 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7325 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Added new function into lib/silcutil/silcschedule.[ch]:
7328 silc_schedule_with_fd to select() a specified fd. The function
7329 returns after timeout expires or data arrives or goes. The
7330 function is used by packet routines to wait that all data is
7331 received from network.
7333 * Fixed data reading from network in lib/silccore/silcpacket.c.
7334 The code now assures that all data is read from the fd and then
7335 continues packet processing. This was a bug fix since the code
7336 used to drop some data in some circumstances.
7338 * Added new function into lib/silcclient/client.[ch]:
7339 silc_client_start_key_exchange to start key exchange after
7340 connection has been established to server. The code internally
7341 now uses this funtion but its main purpose was to provide it
7342 for applications that perform their own connecting. After
7343 application has created a connection it merely calls this
7344 function to start the key exchange between client and server.
7345 The library takes care of everything else after that.
7347 Updated also lib/silcclient/README to explain the usage of
7350 * Do not send to application information that connection has
7351 been established. Application gets notified it by connect
7354 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Applied cras's patch to add silc_schedule_one function. The
7357 function runs scheduler once and returns.
7359 * Fixed the scheduler after cras messed it up. The timeout
7360 handling works now as it's supposed to work.
7362 * Added into lib/silccore/ silcnotify.h to include notify
7363 message types support. Changed silc_server_send_notify*
7364 functions, in server.[ch], to support those new notify types.
7365 Added the support for the notify types into client library,
7366 as well. Added new notify client operation into ops.h in
7369 * Changed silc_server_packet_send_to_channel to send normal
7370 packets instead of just channel message packets. The function
7371 is now used to send the notify packets to channels. It is not
7372 used to send channel message packets anymore, as server never
7375 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7376 va_arg()s as it seems to require it nowadays. I guess, if SILC
7377 is compiled with older va_arg() the new code should work anyway.
7379 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7381 * Splitted core library. Core library (lib/silccore) includes
7382 now only SILC protocol specific core (and common) components.
7383 Created new utility library (lib/silcutil) that includes more
7384 generic purpose stuff. The stuff for util library was taken
7385 from the old core library. This was minor and easy split.
7387 * Created SILC Client Library (lib/silcclient) that includes
7388 implementation of the SILC client without user interface. This
7389 was major move from silc/ directory. The code has been changed
7390 so that it is transparent towards the user interface. The
7391 silc/ directory includes now the same user interface as before
7392 and it uses the new client library. Read lib/silcclient/README.
7393 Basicly, the client library performs everything else related
7394 to SILC except user interface handling. Also, configuration
7395 files are considered to be part of user interface and library
7396 does not handle them.
7398 This change also changed a lot of structures, function naming etc.
7399 Most important change was that SilcClientWindow object was
7400 renamed to SilcClientConnection in the client library. Created
7401 also new file lib/silcclient/ops.h. Also added new files
7402 silc/local_command.[ch] and silc/client_ops.[ch].
7404 All these changes were made to make it easier for user interface
7405 designers to create what ever user interface for the SILC client
7408 It is also expected that the server will be moved to lib
7409 directory as well and SILC Server Library will be created;
7410 sometimes in the future.
7412 * Removed Local commands from lib/silccore/silccommand.h as
7413 they are application specific and new client library does not
7414 handle any of those anymore.
7416 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7417 old client implementation in silc/.
7419 * Added support for callback functions in SILC_LOG_* macros.
7420 Application can now set its own callbacks that will be called
7421 instead of using the default functions that will always print
7422 the debug messages to stderr (or stdout). Also, debugging can
7423 now be disabled by setting silc_debug to FALSE and re-enabled by
7424 setting it to TRUE. Note, that logging will still work even
7425 if debugging is disabled.
7427 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7428 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7429 silc_log_reset_debug_callbacks.
7431 * To enable debugging in silc client one must give now -d
7432 option on command line.
7434 * Changed silc_schedule_init to automatically allocate task queues
7435 if they are not allocated before calling it.
7437 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Added GMP 3.1 into math library.
7441 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7444 a channel in SILC network. The packet is used by servers and
7445 routers to notify other routers that user has left a channel.
7446 This little feature was missing until now. Added the feature
7447 to protocol specification as well.
7449 Added functions: silc_server_send_remove_channel_user and
7450 silc_server_remove_channel_user into server.[ch].
7452 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7453 lib/silccore/silcpacket.h. However, they are not implemented
7456 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Fixed joining to a channel and sending channel messages
7459 between server and router. The channel message sending should
7460 now work inside a cell.
7462 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * Fixed the private message sending between server and router.
7465 The private message sending should now work inside a cell.
7467 * Added silc_server_replace_id into server.[ch] to replace
7468 existing ID in the SILC network.
7470 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7471 and silc_idlist_replace_server_id into idlist.[ch] in server.
7473 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7475 * Fixed the server to server connections. Server can again now
7476 connect to router. Router to router connections probably does
7479 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Added dynamic protocol registering support. Now protocols can
7482 registered and unregistered on the fly. Patch by cras.
7484 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7486 * Added lib/contrib directory to hold routines that some platforms
7487 don't have but are needed by SILC.
7489 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7490 into lin/contrib to provide getopt() and getopt_long() for
7491 those who don't have it.
7493 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Added AWAY command to client. When away message is set and
7496 client receives a private message packet the client automatically
7497 replies to the sender with the away message.
7499 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7500 bug seemed to be the cause of recent problems when compiling
7503 * Added version detection support to SKE protocol specification
7504 and added the new changes to the SKE implementation as well.
7505 There were other minor changes in the SKE protocol as well.
7507 Many changes in lib/silcske/silcske.[ch] and in
7508 lib/silcske/payload.[ch].
7510 * Added ^U functionality, clear input line. Patch from cras.
7512 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7514 * Mainly small bugfixes on core library. Fixed some debugging
7515 logging and buffer overflow in silclog.c.
7517 * Updated config.sub and config.guess on the distribution tree.
7519 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Added command lagging support in server. Client may execute
7522 commands now only once in two seconds.
7524 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Optimized packet reception. MAC computation and checking is now
7527 also more optimized. A lot previously duplicated code is now
7528 used as generic by both client and server.
7530 * Fixed key pair generation in clientutil.c
7532 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Added into lib/silccore/silcbufutil.[ch] new function;
7535 silc_buffer_realloc.
7537 * Moved generic packet sending/encryption functions to
7538 lib/silccore/silcpacket.[ch] from client and server. Some
7539 rewriting of the functions.
7541 * Moved all generic packet reception/decryption functions to
7542 lib/silccore/silcpacket.[ch] from client and server. The
7543 packet processing is now much cleaner in both client and server.
7544 These were major changes in both client and server.
7546 * Created many common functions in server to do packet sending.
7547 Previously code were duplicated a lot, this has been removed
7550 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7552 * Rewrote major parts of the ID cache system. Don't know
7553 whether it is better now or not but at least the API is more
7556 * Major rewrite on ID cache stuff on client because of the ID
7557 cache API changes. Added idlist.c to client.
7559 * Also major rewrite on ID cache stuff on server as well.
7560 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7561 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7562 in hand, instead they are all put into the ID cache system now.
7563 All server_idlist_* routines uses ID cache now instead of
7564 traversing its own lists (those lists does not exist anymore).
7565 SilcIDList though still exists. Also, SilcXXXEntry's are
7568 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7570 * Finally made the SKE implementation compliant to the protocol
7571 specification. All mp integers are now binary encoded as
7572 opposed being HEX encoded.
7574 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7577 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7578 functions: silc_[encode/decode]_pem. Also added function
7579 silc_encode_pem_file to PEM encode with newlines ('\n') for
7582 * SILC public keys are now encoded either PEM or binary. Same
7583 option is for private keys as well. By default private keys
7584 are binary encoded and public keys PEM encoded. Silly HEX
7585 encoding were removed.
7587 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7588 function to create fingerprints.
7590 * Fixed a bug in SHA1; does not change the original data anymore.
7592 * Partly implemented INFO command on client and server side.
7593 Fixed CLEAR command. Changes to SERVER command; show current
7594 server(s) when giving command without arguments. Added
7595 VERSION command to client.
7597 * Added check to server that unregistered connections cannot
7598 execute commands (unless it is specificly allowed).
7600 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Fixed screen refresh.
7604 * Fixed channel joining bug from client. On some circumstances
7605 client tried to join to a channel it had already joined.
7607 * Added public key verification process into client's protocol.c.
7608 The client now verifies the public key from user and saves
7609 it into ~./silc/serverkeys/ directory.
7611 Added into: clientutil.[ch]: silc_client_verify_server_key.
7613 * Changed SKE protocol's silc_ske_initiator_finish function
7614 to accept callback function that verifies the received public
7615 key. Removed old silc_ske_verify_public_key function.
7617 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7619 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7620 silc_pkcs_private_key[_data]_set.
7622 * Made the password and public authentication more cleaner in
7623 server's protocol.c.
7625 * Removed historic and obsolete protocol `channel_auth' from
7626 both client and server.
7628 * Removed wrong way of sending command status messages from
7629 server to client in server's command.c. The old way violated
7630 protocol specification.
7632 Changes to silccore/silccommand.[ch]: removed
7633 silc_command_encode_status_payload -> not needed anymore,
7634 changed silc_command_encode_payload_va to accept extra
7635 argument on variable argument list. The argument type must
7636 now be provided to the function. Also, added new function:
7637 silc_command_encode_reply_payload_va which is same as
7638 normal command_encode_payload_va except command status type
7639 is provided as extra argument.
7641 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7643 * Added ~./silc directory handling. The directory includes the
7644 public and private keys for the client.
7646 Added silc_client_check_silc_dir, silc_client_create_identifier
7647 and silc_client_load_keys.
7649 * Implemented SILC protocol compliant public key. Added public
7650 and private key saving to and loading from files.
7652 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7653 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7654 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7655 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7656 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7658 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7659 silc_pkcs_load_[public/private]_key.
7661 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7663 * Added silc_server_get_route (route.[ch]) to get connection
7664 data for the fastest route for given ID.
7666 * Implemented INVITE command on client and server. The command
7667 were re-defined in the SILC Protocol Specification and the
7668 implementation now complies with the specification.
7670 * Implemented PING command on client and server.
7672 * Implemented NAMES command on client and server. The server side
7673 supports currently only normal server not router server yet.
7674 Some changes to NAMES definition in SILC protocol specification.
7676 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7678 * Implemented LEAVE command on client and server.
7680 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7681 again. This change was made to the protocol as well. Server
7682 should not violate the protocol specification anymore.
7684 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7686 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7687 was tested. SOCKS4 was not but should work anyway.
