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

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

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

612 irssi/src/fe-text/silc.c.
614 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
616 * Added new configuration options and blocks:
617 keepalive_secs, reconnect_count, reconnect_interval,
618 reconnect_interval_max, reconnect_keep_trying and
619 require_reverser_lookup. Added ConnectionParam block, and
620 implemented the connection parameters when connecting as
621 initiator and when accepting connections as responder.

624 whether given configuration value has been given already.
626 Affected files silcd/serverconfig.[c], server.[c].
628 * Splitted the doc/example_silcd.conf.in. Separated the crypto
629 algorithm parts and created new file silcalgs.conf, that
630 is now included from the example_silcd.conf.in.
632 * Optimized the silc_server_connect_to_router_second to take
633 the connection configuration object from the SilcServerConnection
634 object instead of finding it during the connecting phase.
635 Added the configuration object to SilcServerConnection struct.
636 Affected files silcd/server_internal.h, server.c.
638 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

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

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

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

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

897 nice file made available.
899 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * Call silc_server_remove_from_channels when removing client
902 entry when NO_SUCH_CLIENT_ID was received. Affected file
903 is silcd/command_reply.c.
905 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
907 * Added server & router operator statistics updating. Affected
908 file silcd/packet_receive.c and silcd/command.c.
910 * Fixed the SERVER_SIGNOFF notify handling on normal server
911 not to save the history information for clients. Same was
912 fixed earlier in remove_clients_by_server function, but not
913 here. Affected file silcd/packet_receive.c.
915 * Raised the default connection-retry count from 4 to 7 in
916 server. Affected file silcd/server.h.
918 * Cancel any possible reconnect timeouts when we start the
919 key exchange. Affected file silcd/server.c.
921 * Do not reconnect on connection failure when SCONNECT was
922 given. Affected files silcd/server.[ch].

926 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
928 * Fixed the NICK command to always give the unformatted
929 nickname to the one giving the NICK command. If unformatted
930 nickname is cached already it will be formatted and the
931 local entry will always get the unformatted nickname.
932 Affected file lib/silcclient/idlist.c.
934 * Fixed some double frees from client library commands.
935 Affected file is lib/silcclient/command.c.
937 * Fixed CUMODE command in server to assure that no one can
938 change founder's mode than the founder itself, there was a
939 little bug. Affected file silcd/command.c.
941 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
943 * Removed the SilcClientCommandDestructor from the client
944 libary, it is not needed anymore. Affected files are
945 lib/silcclient/silcapi.h, command[_reply].[ch],
946 client_notify, idlist.c.
948 * Fixed GETKEY command to first resolve client, and then
949 resolve the server only if the client was not found, instead
950 of resolving both at the same time. Affected file is
951 lib/silcclient/command.c.
953 * Added silc_client_start_key_exchange_cb and lookup the
954 remote hostname and IP address before starting the key
955 exchange with server. The affected file is
956 lib/silcclient/client.c.
958 * The server's public key is now saved using the IP address
959 of the server and not the servername for the filename.
960 The hostname public key filename is checked as an fall back
961 method if the IP address based filename is not found.
963 Fixed the GETKEY command to save the fetched server key
966 Print the remote server's hostname now when new key is
967 received during connection process. Affected file is
968 irssi/src/silc/core/client_ops.c.
970 * Return always our own public key to the client if it asks
971 for it with GETKEY command. Affected file silcd/command.c.
973 * Removed the use_auto_addr variable from default config
974 file since it was in wrong section. Affected file is
977 * Fixed TOPIC_CHANGE notification to not route it when it
978 was sent using silc_server_send_notify_to_channel function.
979 Affected file silcd/command.c.
981 * Fixed silc_server_send_notify_kicked to send the kicker's
982 Client ID also, it was missing. Affected files are
983 silcd/command.c, silcd/packet_send.[ch].
985 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * Do not save client history information in SERVER_SIGNOFF.
988 Fixes the bug in normal server that it does not detect
989 the client becoming valid after the server becomes back
990 online. Affected file silcd/server_util.c.
992 * Added `sock_error' field into the SilcSocketConnection
993 context. When error occurs during socket operation (read
994 or write) the error is saved. Added also new function
995 silc_socket_get_error to return human readable socket error
996 message. Affected files are lib/silcutil/silcsockconn.[ch],
997 lib/silcutil/unix/silcunixsockconn.c, and
998 lib/silcutil/win32/silcwin32sockconn.c.
1000 * The server now prints the socket error message in the
1001 signoff for client. Affected file silcd/server.c.
1003 * Fixed the `created' channel information sending from router
1004 to server in JOIN command. Checks now whether the channel
1005 really was created or not and set it according that.
1007 Fixed the JOIN command to use the client entry's current
1008 ID during the joining procedure instead of the one it sent
1009 in the command (it is checked though), since it can change
1010 between the packet processing and command processing, and
1011 would just case unnecessary pain in the client end. Affected
1012 file silcd/command.c.
1014 * Fixed a channel key payload sending to use correct channel
1015 ID when the server was forced to change the channel's ID by
1016 router. Router sent the key payload with the old Channel ID.
1017 Affected file silcd/packet_receive.c.
1019 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Call silc_server_save_channel_key only if the key payload
1022 was provided in the JOIN command's command reply. Affected
1023 file silcd/command_reply.c.
1025 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1027 * Fixed silc_mp_sizeinbase to return the value correctly with
1028 MPI. Affected file lib/silcmath/mp_mpi.c.
1030 * Fixed the stop_server signal to correctly stop the scheduler
1031 and gracefully stop the server when SIGTERM or SIGINT signals
1032 are received. Affected file silcd/silcd.c.
1034 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1036 * Simple handling of TERM and HUP signals. Also added some log
1037 flushing call around. Affected file is
1040 * Fixed small bugs in silclog.c. Now buffering output will take
1041 effect after 10 seconds since startup: This will ensure that
1042 no important startup messages are lost. Also output redirection
1043 will preserve original format ([Date] [Type] message).
1044 Affected file is lib/silcutil/silclog.c.
1046 * Added two options to the config file, in the logging section:
1047 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1048 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1050 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1052 * Do not print the warning about log files not being initialized
1053 more than once to avoid excess logging. Affected file is
1054 lib/silcutil/silclog.c.
1056 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1057 the SIM copying in make install in Makefile.am.pre.
1059 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1061 * Rewritten silclog APIs. Globally interesting changes follows:
1062 silc_log_set_files() changed to silc_log_set_file().
1063 silc_log_set_callbacks() changed to silc_log_set_callback().
1064 ROBOdoc documented silclog header file.
1065 SilcLogCb now returns bool to wether inihibit the default
1066 handler or not (to keep the old behaviour return always TRUE).
1067 The new APIs should also fix the problem of the
1068 silcd_error.log file that was written in the current directory.
1071 Log files streams will remain opened after silc_log_set_file()
1072 call, means less CPU usage notably on high traffic servers.
1073 File streams are now full buffered, and flushed to the disk
1074 every 5 minutes, lesses HD activity and CPU usage.
1075 Messages can be redirected, allowing admins to configure
1076 one single logfile for all server messages.
1077 the silc_log_quick global variable to activate fast-logging.
1078 Affected files lib/silcutil/silclog.[ch]
1080 * Changed some code to conform new silclog APIs. Affected
1081 files are doc/example_silcd.conf.in, silcd/server.c
1082 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1085 * Fixed a memory leak that could occur in some situations.
1086 Affected file silcd/serverconfig.c.
1088 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * Added the silc_client_del_client to remove the client from
1091 all channels as well. Affected file lib/silcclient/idlist.c.
1093 * Fixed the client library to correctly remove the client
1094 from all channels when the client entry is being destroyed.
1095 Affected file lib/silcclient/client_notify.c, command.c.
1097 * Added auto-nicking support to the client library. If the
1098 applicatio now sets client->nickname it will be sent to the
1099 server after connecting by the library. This way for example
1100 SILCNICK (or IRCNICK) environment variables will have effect
1101 and always change the nickname automatically to whatever
1102 it is wanted. Affected file lib/silcclient/client.[ch].
1104 * Renamed silc_server_command_bad_chars to the
1105 silc_server_name_bad_chars and moved it to the
1106 silcd/server_util.[ch]. Added also new function
1107 silc_server_name_modify_bad to return nickname that
1108 includes bad characters as new nickname without those
1109 bad characters. This check and modify is now used in
1110 silc_server_new_client when the username is initially set
1111 as nickname, so it must be checked to be valid nickname.
1112 Affected file silcd/packet_receive.c.
1114 * The nickname length is now taken from the packet for real
1115 and not trusted to strlen() since it clearly can return
1116 wrong length for nickname including bad characters. This
1117 also applies to channel names. Affected file silcd/command.c.
1119 * Removed the lib/silcsilm/modules directory. Modules are now
1120 compiled into the lib/silcsim. Fixed the copying of the
1121 modules to follow symbolic links in Makefile.am.pre.
1123 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1125 * Fixed silc_string_regexify list creation. Fixes bugs with
1126 BAN and INVITE commands in server. The affected file is
1127 lib/silcutil/unix/silcunixutil.c.
1129 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Removed the command destructor entirely from the server's
1132 command and command reply routines. It is not needed, and
1133 its usage was buggy and caused crashes. Affected files are
1134 silcd/command[_reply].[ch].
1136 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Cancel protocol and NULL sock->protocol if timeout
1139 occurred during protocol. Affected file silcd/server.c.
1141 * Cancel protocol timeouts always before calling the final
1142 callback, to assure that after final callback is called
1143 no other state will be called for the protocol anymore.
1144 Affected file silcd/protocol.c.
1146 * Print error log if incoming connection configuration could
1147 not be found. Affected file silcd/server.c.
1149 * Fixed JOIN command to correctly save the founder mode
1150 to the client on normal SILC server, when the channel
1151 was created by the router. Affected file silcd/command.c.
1153 * Fixed LIST command (hopefully) to send correct reply
1154 packets. Affected file silcd/command.c.
1156 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * The silc_packet_receive_process now returns FALSE if the
1159 read data was invalid packet, and TRUE if it was ok.
1161 The server now checks that if unauthenticated connection
1162 sends data and its processing fails the server will close
1163 the connection since it could be a malicious flooder.
1165 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1167 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Make sure the warning about error opening a log file is
1170 printed only once and not everytime it fails (produces
1171 too much useless log). Affected file lib/silcutil/silclog.c.
1173 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1175 * Made the silc_server_daemonise() function more readable.
1176 Affected file silcd/server.c.
1178 * Pid file is now optional, the user may comment it out from
1179 the config file. Removed define SILC_SERVER_PID_FILE, we
1180 don't need a default any longer. Affected file
1181 configure.in.pre, lib/Makefile.am.pre.
1183 * Make some use of the pid file. The server now dies at startup
1184 if it detects a valid pid file on his path. The server would
1185 die anyway in this circumstance, because of the bind() failure.
1186 Affected file silcd/silcd.c.
1188 * No longer compiling lib/dotconf.
1190 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Fixed JOIN command parsing not to crash. Affected file
1193 lib/silcclient/command.c.
1195 * Fied the NICK_CHANGE notify to add the new client entry
1196 even it is resolved. This removes an <[unknown]> nick
1197 thingy bug in the client. Affected file is
1198 lib/silcclient/client_notify.c.
1200 * Do not try to allocate 0 bytes (efence does not like it)
1201 in lib/silccore/silccomand.c when encoding payload.
1203 * Do not take IRCNICK as nickname in Irssi SILC client since
1204 it is not possible to set nickname before hand connecting
1205 the server (TODO has an entry about adding auto-nicking
1208 * Changed the silc_server_command_pending to check whether
1209 there already exists an pending entry with the specified
1210 command, command identifier and pending callback. This is
1211 to fix IDENTIFY and WHOIS related crashes that may register
1212 multiple pending commands with same identifier. Affected
1213 file silcd/command.c.
1215 * Fixed the server to reconnect to the router even if it
1216 was already reconnecting and EOF was received. This to
1217 fix a possibility that the server wouldn't ever try to
1218 auto-reconnect to the router. Affected file silcd/server.c.
1220 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Fixed the server's password authentication to use the
1223 length of the locally saved password, and not the one
1224 sent in the packet. Affected file silcd/protocol.c.
1226 * Fixed same password authentication problem in the
1227 Authentication Payload handling routines in
1228 lib/silccore/silcauth.c.
1230 * Yet another password authentication problem fixed with
1231 channel password handling in silcd/command.c.
1233 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * If first character of string in silc_parse_userfqdn is '@'
1236 then do not parse it. Affected file is
1237 lib/silcutil/silcutil.c.
1239 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * Fixed minor bug in IDENTIFY command reply sending, which
1242 caused various weird problems during JOIN when it was
1243 resolving names for users. Affected file silcd/command.c.
1245 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Fixed the IDENTIFY command reply sending to chech better valid
1248 clients. It was possible to send incomplete list of replies.
1249 Affected file silcd/command.c.
1251 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Added silc_client_command[s]_[un]register functions now to
1254 dynamically register the commands in client library. Removed
1255 the static table of commands. This allows the client library
1256 to call commands without causing the application to know about
1257 what commands library has called.
1259 Removed the INFO command reply kludge to detect when the command
1260 was called by library. Now library use its own command reply
1261 function for INFO command.
1263 Added function silc_client_command_call to call a command.
1264 Application can use it to call command, not access the structure
1267 Now all commands that are sent by the client library (not
1268 explicitly sent by application) use own command reply functions.
1270 Affected files around lib/silcclient/ and in
1271 irssi/src/silc/core/.
1273 * Fixed the WHOIS command reply sending to chech better valid
1274 clients. It was possible to send incomplete list of replies.
1276 Fixed the WHOIS and IDENTIFY to send the request to router
1277 if normal server did not do it and did not find any results.
1279 Affected file silcd/command.c.
1281 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Moved the internal data from SilcClient context into its
1284 own file, not accesible to application. Affected files
1285 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1286 and other files in client library.
1288 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Added doc/examples installation target in Makefile.am.pre.
1293 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1296 commands the found client entry will be removed from the
1297 cache, after notifying application about the error. Affected
1298 file lib/silcclient/command_reply.c.
1300 * Changed the /MSG to check for exact nickname user gave, and
1301 not let `nick' match `nick@host' if it is only one found. Now,
1302 user must type the exact nickname (like nick@host2) even if
1303 there are no more than one same nicks found. This is to avoid
1304 a possibility of sending nickname to wrong nickname since
1305 `nick' could match `nick@host'. Affected file is
1306 irssi/src/core/silc-servers.c.
1308 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Do not print "you are now server operator" or similar when
1311 giving /away command. Affected files are
1312 irssi/src/silc/core/client_ops.c, silc-servers.h.
1314 * Made the silc_server_command_pending_error_check to send
1315 the same command reply payload it received back to the
1316 original sender of the command. This way all arguments
1317 that was received by the server will be received by the
1318 client too. Affected file silcd/command.c.
1320 * Added the silc_idcache_add to return the created cache entry
1321 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1323 * Add global clients to expire if they are not on any channel.
1324 This is because normal server will never know if they signoff
1325 if they are not on any channel. The cache expiry will take
1326 case of these entries. This is done by normal servers only.
1327 The affected files are silcd/command_reply.c,
1328 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1330 * If server receives invalid ID notification for WHOIS or
1331 IDENTIFY and the ID exists in the lists, it is removed.
1332 Affected file silcd/command_reply.c.
1334 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1335 in client then client entry that it matches is searched and
1336 the nickname is printed on the screen for user. Affected
1337 file irssi/src/silc/core/client_ops.c.
1339 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1341 * Use cache entry expire time in the LIST command reply to
1342 purge old entries from the cache after the LIST command
1343 reply has been received. This way we don't have non-existent
1344 entries in the cache for too long. Affected file is
1345 silcd/command_reply.c.
1347 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1349 * If we are normal server, and we've not resolved client info
1350 in WHOIS or IDENTIFY from router, and it is global client,
1351 we'll check whether it is on some channel. If it is not
1352 then we cannot be sure about its validity and will resolve it
1353 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1354 file silcd/command.c.
1356 * Search channel by name (if possible) rather than by ID
1357 in IDENTIFY command's command reply. Affected file is
1358 silcd/command_reply.c.
1360 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1363 Updated specs and implemented it. Affected file silcd/command.c,
1364 silcd/packet_send.c and silcd/packet_receive.c.
1366 * Implemented the <founder auth> payload handling in the JOIN
1367 command. If provided all conditions for channel joining
1368 except requirement to provide correct passphrase can be
1369 overrided by the channel founder. Updated the protocol specs.
1370 Affected file silcd/command.c.
1372 Added support for founder auth in JOIN command in client
1373 library. Fixed the parsing of the JOIN command now to support
1374 all options as they should be. The affected file is
1375 lib/silcclient/command.c.
1377 * Optimized the WHOIS and IDENTIFY commands to send the request
1378 to router only if it includes nicknames or other names. If
1379 they include only IDs then check the local cache first before
1380 routing. Affected file is silcd/command.c.
1382 * Added channels topic announcements. Affected file is
1383 silcd/packet_receive.c and silcd/server.c.
1385 * Fixed the silc_server_send_notify_topic_set to really destine
1386 the packet to channel. Affected file silcd/packet_send.c.
1388 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1389 library. Affected file lib/silcclient/client_notify.c.
1391 * Added UMODE announcements. Affected file silcd/server.c.
1393 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * Memory leak fixes in:
1397 lib/silcutil/silcsockconn.c
1398 lib/silcske/silcske.c
1399 lib/silcske/groups.c
1401 lib/silccrypt/silcpkcs.c
1402 lib/silccore/silccommand.c
1403 lib/silccore/silcidcache.c
1408 * ROBOdoc documented the lib/silcske/groups.h file and a
1409 bit changed the interface for better.
1411 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1413 * Update the client entry context in the ID cache after
1414 nick change. Affected file lib/silcclient/command.c.
1415 Fixes the CUMODE command when regaining founder privileges,
1416 and a little WHOIS problem.
1418 * Fixed silc_net_gethostbyname to correctly call the
1419 inet_ntop. Affected file lib/silcutil/silcnet.c.
1421 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1423 * Added IPv6 support checking to the configure.in.pre, added
1424 also --enable-ipv6 option to override the check. Affected
1425 file configure.in.pre.
1427 * The silc_thread_create now calls the start function
1428 directly if threads support is not compiled in. Removes
1429 ugly #ifdef's from generic code. Affected files are
1430 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1432 * Added silc_net_gethostby[name/addr]_async to asynchronously
1433 resolve. Affected files are lib/silcutil/silcnet.[ch].
1435 * Added support for rendering IPv6 based server, client and
1436 channel IDs. Affected file lib/silcutil/silcutil.c.
1438 * Added support for creating IPv6 based server IDs. Affected
1439 file is silcd/serverid.c.
1441 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1443 * Added silc_net_gethostby[addr/name] into the
1444 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1445 routines. Added silc_net_is_ip[4/6]. Affected file is
1446 lib/silcutil/unix/silcunixnet.c. All routines that take
1447 address as argument now supports both IPv4 and IPv6 addresses.
1449 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1451 * Fixed LIST command reply sending in server. Affected file
1454 * Server now sends the kicker's client ID in the KICK notify
1455 to the kicked client. Affected file silcd/command.c.
1457 * The client library now parses the kickers client ID and
1458 UI displays it. Affected files lib/silcclient/client_notify.c
1459 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1461 * Made all payload parsing function prototypes consistent.
1462 They all take now const unsigned char * and uint32 pair as
1463 the payload data instead of SilcBuffer. Changes all around
1464 the source tree. Other unsigned char* -> const unsigned char*
1465 changes around the tree as well.
1467 * Optimized SFTP client and server packet sending not to
1468 allocate new buffer for each packet but to recycle the
1469 first allocated buffer. Affected files are
1470 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1472 * Optimized the SFTP client to use SilcList instead of
1473 SilcDList for requests, because it is faster. Affected file
1474 is lib/silcsftp/sftp_client.c.
1476 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1477 into lib/silccore/silcid.[ch].
1479 Renamed silcpayload.[ch] into silcargument.[ch].
1481 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1483 * If client entry is deleted with active key agreement
1484 session, abort the session.
1486 The silc_client_abort_key_agreement now calls the completion
1487 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1489 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1492 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1494 * Don't use __restrict in older GCC's. Affected file is
1495 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1497 * silc_net_localhost now attempts to reverse lookup the
1498 IP/hostname. Affected file lib/silcutil/silcnet.c.
1500 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1501 command. It can be used to gain founder privileges at
1502 the same time when joining the channel.
1504 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1505 kicker's client ID as well. Updated protocol specs.
1507 Defined that the server must send SILC_COMMAND_IDENTIFY
1508 command reply with error status to client who sent
1509 private message with invalid client ID.
1511 Updated the protocol specification.
1513 * Added silc_server_send_command_reply to send any
1514 command reply. Affected file silcd/packet_send.[ch].
1516 * Added silc_id_payload_encode_data to encode ID payload
1517 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1519 * The server now send IDENTIFY command reply with error
1520 status if client ID in private message is invalid. Affected
1521 file silcd/packet_receive.c.
1523 * Save the server key file with server's IP address in
1524 the filename instead of hostname. The affected file is
1525 irssi/src/silc/core/client_ops.c.
1527 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1529 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1532 * Added libtool support for compiling shared objects in
1533 lib/silcsim. Affected file configure.in.pre and
1534 lib/silcsim/Makefile.am. Original patch by cras.
1536 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Pid file configuration, and server's config file fixes
1539 patch by toma. Updated CREDITS file.
1541 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Fixed silc_client_channel_message to not try to decrypt
1544 the message twice if it resolved the destination client
1545 information. This could cause of dropping one channel
1546 message. Affected file lib/silcclient/client_channel.c.
1548 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1551 lib/silcclient/client.c. This function is used when the SILC
1552 Client is run under some other scheduler, or event loop or
1553 main loop. On GUI applications, for example this may be
1554 desired to used to run the client under the GUI application's
1555 main loop. Typically the GUI application would register an
1556 idle task that calls this function multiple times in a second
1557 to quickly process the SILC specific data.
1559 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1561 * Fixed silc_server_drop() for dropping the supplementary
1562 groups as well, this could cause a security hole on some
1565 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1570 * Write PID file after dropping privileges. Added -F option
1571 to run server on foreground. A patch by debolaz.
1572 Affected files silcd/server.c, silcd/silcd.c.
1574 * Fixed MOTD to return the MOTD file server name. Affected
1575 file silcd/command.c.
1577 * Added INFO command reply handling to the Irssi SILC Client.
1578 Affected file irssi/src/silc/core/client_ops.c.
1580 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Fixed the silc_idcache_list_* routines to really support
1583 the dynamic list. Fixes a crash. Affected file is
1584 lib/silccore/silcidcache.c.
1586 * Fixed the LIST command reply to really call LIST command's
1587 pending callbacks. Affected file silcd/command_reply.c.
1589 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Update conn->local_entry->nickname after giving NICK
1592 command. Affected file lib/silcclient/command.c.
1594 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1596 * Added the [pid] option to the silcd configuration file
1598 Affected files: serverconfig.[ch] and silcd.c
1600 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Save fingerprint in WHOIS command reply in server.
1603 Affected file silcd/command_reply.c.
1605 * Fixed NICK commands pending callback registration.
1606 Affected file lib/silcclient/command.c.
1608 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1610 * Use ++server->cmd_ident when sending commands in server,
1611 instead of random number. Affected file silcd/command.c.
1613 * Fixed GETKEY command reply to call actually GETKEY pending
1614 command callbacks. Affected file silcd/command_reply.c.
1616 * A bit stricter check for nicknames. Check for same nickname
1617 in NICK command also. Affected file silcd/command.c.
1619 * Do not call INFO command everytime client ID changes, only
1620 during first connecting. Affected file lib/silcclient/client.c.
1622 * Set the new nickname only after successful command reply for
1623 NICK command is returned by server. Affected file
1624 lib/silcclient/command.c.
1626 * Remove nicknames from nicklist during server_signoff notify.
1627 Should fix /NAMES bit more. The affected file is
1628 irssi/src/silc/core/silc-channels.c.
1630 * Added `fingerprint' field to the SilcIDListData in the
1631 silcd/idlist.h to hold the fingerprint of the client's
1634 Send the fingerprint of the client's public key in WHOIS
1637 Affected files silcd/command.c, and silcd/idlist.[ch].
1639 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1640 create fingerprint from given data.
1642 * Show the fingerprint of the client's public key in WHOIS.
1643 Affected files irssi/src/module-formats.[ch] and
1644 irssi/src/silc/core/client_ops.c.
1646 * Format the multiple same nicknames also during JOIN and
1647 NICK_CHANGE notifys. Affected file is
1648 lib/silcclient/client_notify.c.
1650 * Do not print error on screen for invalid private message
1651 payload since it can come if someone is sending private
1652 messages with wrong key. Affected file
1653 lib/silccore/silcprivate.c.
1655 * Fixed multiple concurrent /PING crash. Affected file
1656 lib/silcclient/command.c.
1658 * Changed the wrong ID encoding. All IP addresses must be
1659 in MSB first order in encoded format. They were encoded
1660 wrong and was in LSB format. Affected files are
1661 silcd/serverid.c, lib/silcutil/silcutil.c.
1663 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1665 * Call the `connect' client operation through the scheduler
1666 in case of error. Affected file lib/silcclient/client.c.
1668 * Call the `failure' client operation even if the error
1669 occurred locally during a protocol. Affected file is
1670 lib/silcclient/protocol.c.
1672 * Added support of sending LIST command to router from normal
1673 server. This way normal server can get list of all channels
1674 in the network too. Fixed the channel list sending in the
1675 server too. Affected files are silcd/command.c, and
1676 silcd/command_reply.[ch].
1678 * Added silc_server_update_channels_by_server and
1679 silc_server_remove_channels_by_server. They are used during
1680 disconnection of primary router and in backup router protocol.
1681 Affected file silcd/server_util.[ch], silcd/server.c and
1682 silcd/server_backup.c.
1684 * Fixed channel adding to global list in IDENTIFY command
1685 reply in server. Affected file silcd/command_reply.c.
1687 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * If the incoming packet type is REKEY or REKEY_DONE process
1690 that packet always synchronously. Fixes yet another MAC
1691 failed error on slow (dialup) connections. Affected file
1692 lib/silcclient/client.c and silcd/server.c.
1694 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Call check_version SKE callback for initiator too. Affected
1697 file lib/silcske/silcske.c.
1699 * Implemented fix for security hole found in the SKE that was
1700 fixed in the specification few days back; the initiator's
1701 public key is now added to the HASH value computation.
1702 Added backwards support for the old way of doing it too, for
1703 old clients and old servers. Affected file is
1704 lib/silcske/silcske.c.
1706 * Enabled mutual authentication by default in SKE. If initiator
1707 is not providing mutual authentication the responder will
1708 force it. This will provide the proof of posession of the
1709 private key for responder. The affected files are
1710 lib/silcclient/protocol.c and silcd/protocol.c.
1712 * Do not cache anymore the server's public key during SKE.
1713 We do mutual authentication so the proof of posession of
1714 private key is done, and if the server is authenticated in
1715 conn auth protocol with public key we must have the public
1716 key already. Affected file silcd/protocol.c.
1718 * Added new global debug variable: silc_debug_hexdump. If
1719 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1720 file lib/silcutil/silclog.[ch].
1722 * Fixed compilation warning due to char * -> const char *.
1723 Affected files lib/silcutil/silcnet.h, and
1724 lib/silccore/silcauth.[ch].
1726 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Fixed CMODE command when new channel key was created. If
1729 the creation failed the old key was removed. Next time giving
1730 same command would crash the server since the old key was
1731 freed already. Affected file silcd/command.c.
1733 * Fixed the silc_server_announce_get_channels to not crash
1734 on reconnect. Affected file silcd/server.c.
1736 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Added silc_log_set_debug_string function to set a regex
1739 string to match for debug output. Only the function names,
1740 or filenames matching the given debug string is actually
1741 printed. This way it is possible to filter out those debug
1742 strings that user is not interested in.
1744 Fixed a bug in silc_string_regexify.
1746 Affected files lib/silcutil/silclog.[ch], and
1747 lib/silcutil/unix/silcunixutil.c.
1749 * Changed the -d options in both server and Irssi SILC client
1750 to take the debug string as argument. Affected files
1751 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1753 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Added silc_hash_babbleprint to create a Bubble Babble
1756 Encoded fingerprint. The encoding is developed by Antti
1757 Huima (draft-huima-babble-01.txt), and it creates human
1758 readable strings out of binary data. Affected file
1759 lib/silccrypt/silchash.[ch].
1761 * Print the babble print now in addition of fingerprint as well
1762 in Irssi SILC client. Affected files are
1763 irssi/src/fe-common/silc/module-formats.[ch],
1764 irssi/src/fe-common/silc/core/client_ops.c.
1766 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Fixed a security problem found in SKE. The initiator's
1769 public key too is now added to the HASH hash value creation
1770 which is signed by the responder to create the SIGN value.
1771 This will prevent anyone in the middle to lie to the responder
1772 about the initiator's public key. If this is done now, the
1773 man in the middle will get caught. Updated the protocol
1776 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Better installation directory handling. Configure module
1779 paths and other paths automatically to example_silc* files
1780 in doc/. A patch by toma.
1782 * Fixed compiler warning from MPI library, and from SILC RNG.
1785 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1786 It can be configured with ./configure. A patch by toma.
1788 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Find correct make to use in prepare-clean. A patch by
1791 toma. Affected file prepare-clean.
1793 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1795 * Added irssi variables use_auto_addr, auto_bind_ip,
1796 auto_bind_port and auto_public_ip.
1798 * Changed the interface for silc_client_send_key_agreement
1799 in lib/silcclient/silcapi.h
1803 irssi/src/silc/core/silc-core.c
1805 lib/silcclient/silcapi.h
1806 irssi/src/silc/core/silc-channels.c
1807 lib/silcclient/client_keyagr.c
1810 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * Added silc_pkcs_public_key_compare to compare two
1813 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1815 * Check that the client who set the founder mode on the
1816 channel is the same client that is giving the founder
1817 mode to itself. It is done by comparing the saved public
1818 key (it is saved even in the authentication is passphrase).
1819 Affected file silcd/command.c.
1821 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Do not process packet for disconnected socket connection.
1824 Affected file lib/silccore/silcpacket.c.
1826 * Process the DISCONNECT packet through scheduler in the
1827 client library. Affected file lib/silcclient/client.c.
1829 * Fixed the silc_client_packet_parse to not to increase
1830 the packet sequence number if the conn->sock and the
1831 current socket connection is not same. This can happen
1832 for example during key agreement when the conn includes
1833 multiple socket connections (listeners). Affected file
1834 lib/silcclient/client.c.
1836 * The sender of the file transfer request now provides also
1837 the pointer (listener) for the key exchange protocol. If
1838 the listener cannot be created then it sends empty key
1839 agreement and lets the receiver provide the listener.
1841 Added `local_ip' and `local_port' arguments to the
1842 silc_client_file_send. If they are provided they are used,
1843 if not then it will attempt to find local IP address, if
1844 not found or bind fails then the remote client will provide
1847 Affected files are lib/silcclient/client_ftp.c and
1848 lib/silcclient/silcapi.h.
1850 * Extended the FILE SEND command to support defining the
1851 local IP and port for key exchange listener. They are
1852 optional. Affected file irssi/src/silc/core/silc-servers.c.
1854 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Defined to WHOIS command reply the sending of fingerprint
1857 of the client's public key (if the proof of posession of the
1858 corresponding private key is verified by the server).
1859 Updated to the protocol specification.
1861 * Added support of receiving the client's public key's
1862 fingerprint in command reply in client library. Affected
1863 file is lib/silcclient/command_reply.c, and
1864 lib/silcclient/idlist.[ch].
1866 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Do not send over 128 chars long nickname to the server
1869 in NICK command. Affected file lib/silcclient/command.c.
1871 * Do not send over 256 chars long channel names to the server
1872 in JOIN command. Affected file lib/silcclient/command.c.
1874 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Assure that silc_server_close_connection cannot be called
1877 twice for same socket context. Affected file is
1880 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1882 * Send error message to application if opening file for
1883 writing during file transfer fails. Affected file is
1884 lib/silcclient/client_ftp.c.
1886 Remove all file transfer sessions for a client that we're
1887 removing from ID cache.
1889 Affected file is lib/silcclient/client_ftp.c.
1891 * Fixed silc_net_addr2bin to return correct address. Affected
1892 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1894 * Fixed file transfer session removing on signoff notify.
1895 Affected file irssi/src/silc/core/silc-servers.c.
1897 * Added the SilcClientFileError to be returned in the monitor
1898 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1899 Affected file lib/silcclient/silcapi.h.
1901 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Fixed a crash in silc_client_ftp_free_sessions and
1904 silc_client_ftp_session_free_client. Affected file
1905 lib/silcclient/client_ftp.c.
1907 * Added `disabled' field in the SilcChannelEntry in the server
1908 to indicate if the server entry is disabled. Affected file
1909 silcd/idlist.h, silcd/command[_reply].c.

1918 * Fixed a crash in client resolving in client_prvmsg.c in
1919 client library. Affected file lib/silcclient/client_prvmsg.c.
1921 * Do not actually remove the client directly from ID cache
1922 during SERVER_SIGNOFF, but invalidate it. This way we
1923 preserve the WHOWAS info for the client. Affected file
1924 silcd/server_util.c.
1926 * Fixed SERVER_SIGNOFF notify handling in the server. The
1927 server is now able to process incoming SERVER_SIGNOFF notify
1928 for a server that it doesn't even know about. It will remove
1929 the clients provided in the notify. Affected file
1930 silcd/packet_receive.c.
1932 * Check for partial packet in data queue after every packet that
1933 was found from the queue. Return and wait for more data if
1934 there is partial data in queue. Affected file is
1935 lib/silccore/silcpacket.c.
1937 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Added SilcClietFileError enum to indicate error in
1940 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1941 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1942 Affected files lib/silcclient/silcapi.h and
1943 lib/silcclient/client_ftp.c.
1945 * Check that newsize in silc_buffer_realloc is larger than
1946 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1948 * Added better monitor of file transfers. It now monitors
1949 key agreement protocol during the file transfer too. Added
1950 error reporting too. Affected files
1951 irssi/src/silc/core/silc-servers.c,
1952 irssi/src/fe-common/silc/module-formats.[ch].
1954 * Wrote a help file for FILE command.
1956 * Added silc_rng_global_get_byte_fast to get not-so-secure
1957 random data as fast as possible. Random data is read from
1958 /dev/urandom if available and from the SILC RNG if not
1959 available. It is used in padding generation. Affected file
1960 lib/silccrypt/silcrng.[ch].
1962 * All packets in client library are now processed synchronously.
1963 Optimized packet processing a lot. Affected file
1964 lib/silcclient/client.c.
1966 * All server connection packets are processing synchronously
1967 now in server, to optimize packet processing. Affected file
1970 * Include files are installed now only in Toolkit distribution
1971 if make install is given. Affected files: all Makefile.am's.
1973 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Assure that silc_client_notify_by_server_resolve does not
1976 resolve the client information multiple times. If it cannot
1977 be found by the first it cannot be found at all. Affected
1978 file lib/silcclient/client_notify.c.
1980 * Fixed WHOWAS command reply calling. Affected file
1981 lib/silcclient/command_reply.c.
1983 * Removed all references to silc_idlist_get_client from the
1984 Irssi SILC client since that call is internal call used by
1985 the library. The Irssi SILC client will use now client
1986 retrieval functions found in silcapi.h.
1988 * Fixed a bug in resolving nickname info before sending
1989 private message. It used freed memory. Affected file
1990 irssi/src/silc/core/silc-servers.c.
1992 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1994 * Assure my_channels statistics cannot go negative in server.
1995 Affected files silcd/server.c, silcd/server_util.c.
1997 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2007 lib/sftp/sftp_fs_memory.c.
2009 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Added silc_net_localip to return local host's IP address.
2012 Affected file lib/silcutil/silcnet.[ch].
2014 * If key exchange or rekey protocol is active for a connection
2015 parse all packets syncronously since there might be packets
2016 in packet queue that we are not able to process without first
2017 processing packets before them. Affected file silcd/server,
2018 lib/silcclient/client.c.
2020 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2021 whether library should continue processing the packet.
2022 Affected file lib/silccore/silcpacket.h.
2024 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2025 SilcSFTPMonitorData to SFTP server to monitor various
2026 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2027 lib/silcsftp/sftp_server.c.
2029 * Added silc_file_size to return file size. Affected file

2034 transmission. Affected file lib/silcclient/client_ftp.c,
2035 lib/silccilent/client.[ch].
2037 * Added new local command FILE to the Irssi SILC Client.
2038 It is used to perform the file transfer. It has subcommands
2039 SEND, RECEIVE, SHOW and CLOSE. Affected files
2040 irssi/src/silc/core/client_ops.c,
2041 irssi/src/silc/core/silc-server.[ch].

2050 * Renamed silc_file_read and silc_file_write to functions
2051 silc_file_readfile and silc_file_writefile. Added function
2052 silc_file_open and silc_file_close. Affected files
2053 lib/silcutil/silcutil.[ch].
2055 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Resolve the client info when received private message or
2058 channel message for a client which nickname we don't know.
2059 Affected files lib/silcclient/client_prvmsg.c and
2060 lib/silcclient/client_channel.c.
2062 * Do not crash in /KEY if client is not connected. Affected

2066 lib/silcclient/idlist.h.
2068 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2069 is incomplete and is being resolved, it won't be resolved
2072 Make sure also that USERS command reply does not resolve
2073 twice information. Affected file is
2074 lib/silcclient/command_reply.c.
2076 Make sure that silc_client_get_clients_by_list does not
2077 resolve twice same information.
2079 * Check for valid client->id in the silc_server_free_client_data.
2080 Affected file silcd/server.c.
2082 * Fixed /GETKEY nick@server not to crash if the server entry
2083 is not found. Affected file lib/silcclient/command.c.
2085 * Fixed the silc_server_check_cmode_rights to check the
2086 requested modes correctly. Affected file silcd/command.c.
2088 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Better checks for non-printable chars in nick added.
2091 Affected file silcd/command.c.
2093 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Call the silc_server_udpate_servers_by_server in the
2096 primary router that comes back online in the backup resuming
2097 protocol. Otherwise it routes packets wrong. Affected file
2098 silcd/server_util.[ch], silcd/server_backup.c.
2100 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2103 lib/silcutil/silcbuffmt.[ch].
2105 * Redefined the SILC packet header to include the padding
2106 length. Affected file lib/silccore/silcpacket.[ch].
2108 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2109 length for maximum padding up to 128 bytes). Affected
2110 file lib/silccore/silcpacket.h.
2112 * Removed all backwards support for old 0.5.x MAC thingies.
2113 The SILC packet header change makes it impossible to be
2114 backwards compatible.
2116 * Send the ENDING packet with timeout in the backup resuming
2117 protocol. This is to assure that all routers has connected
2118 to the primary router. Affected file silcd/server_backup.c.
2120 * Changed the RNG to take the first IV from random data. It
2121 used to take it from zero actually. Changed the RNG also
2122 to use /dev/urandom during session. /dev/random is used
2123 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2125 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Changed the SILC packet header to have the first two bytes
2128 (the packet length) encrypted. Affected files aroung the
2129 code tree, lib/silccore/silcpacket.[ch]. Removed the
2130 SilcPacketCheckDecrypt callback. It is not needed anymore
2131 since the silc_packet_receive_process will determine now
2132 whether the packet is normal or special.
2134 * Implemented the unidirectional MAC keys. Affected files
2135 lib/silcske/silcske.c, silcd/protocol.c and
2136 lib/silcclient/protocol.c.
2138 * Implemented the packet sequence number to the MAC computation.
2139 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2140 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2141 lib/silcclient/protocol.c.
2143 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Allow backup router to announce servers. All servers
2146 announced by backup router are added to the global list
2147 automatically. Update hte server's socket to our primary
2148 router also when backup router announces a server.
2149 Affected file silcd/packet_receive.c.
2151 * Do not update the client->router in the function
2152 silc_server_udpate_clients_by_server if the client is on
2153 global list. We might fail to find any specific server
2154 for locally connected clients and local cell clients. They
2155 should still use the `from' and not `to' as client->router.
2156 This fixes backup router resuming protocol. Affected file
2157 silcd/server_util.c.
2159 * Decrease channel statistics count only if the channel
2160 deletion worked. Affected files are silcd/server.c and
2161 silcd/server_util.c.
2163 * Added silc_server_update_servers_by_server to update origin
2164 of all server entries. Used during backup router protocol.
2165 Affected files silcd/server_util.[ch], silcd/server.c. and
2166 silcd/backup_router.c.
2168 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2169 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2170 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2171 lib/silccrypt/silchmac.c.
2173 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Assure that router cannot reroute the same channel message
2176 to the sender. Affected file silcd/packet_receive.c.
2178 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Made better checks that the channel message is not sent
2181 to the router it came from. Affected file is
2182 silcd/packet_send.c. Fixed memory leak too.
2184 * Announce informations for incoming router connection, but
2185 only after checking if it is replaced by backup router.
2186 Affected file silcd/packet_receive.c.
2188 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Fixed the backup resuming protocol to work in multiple
2191 router environment. Affected file silcd/server_backup.c.
2193 * Route packet only to one router in the function
2194 silc_server_packet_send_to_channel. Affected file is
2195 silcd/packet_send.c.
2197 * Fixed silc_server_send_notify_dest to set the broadcast
2198 flag. Fixed the silc_server_send_notify_topic to actually
2199 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2200 Affected file silcd/packet_send.c.
2202 * Changed the SFTP Filesystem interface. Changed the
2203 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2204 the filesystem operation function. The SilcSFTPFilesystem
2205 is now a context that is allocated by all filesystem allocation
2206 functions and it already includes the operations structure
2207 and filesystem specific context. It is given as argument
2208 now to the silc_sftp_server_start. This made the interface
2209 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2210 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2212 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Changed the backup router adding and getting interfaces
2215 in the server. The router that will be replaced by the
2216 specified backup router is now sent as argument. Affected
2217 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2220 * Added silc_net_addr2bin_ne to return the binary form of
2221 the IP address in network byte order. Affected files
2222 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2224 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Check for existing server ID in silc_server_new_server
2227 and in silc_server_connect_to_router_final and remove the
2228 old entry if it exists. Affected file silcd/packet_receive.c,
2231 * Send the channel message always to only one router, either
2232 in upstream or downstream. Affected file is
2233 silcd/packet_send.c.
2235 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Wrote the definition of the backup resuming protocol to the
2238 protocol specification.
2240 * Removed one redundant channel key generation from normal
2241 server during joining procedure. Removed one redundant
2242 channel key sending from server to router during joining
2243 procedure. Affected file silcd/command.c.
2245 * Made minor bugfixes to the backup router resuming protocol.
2246 Affected file silcd/server_backup.c, server.c.
2248 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Added --disable-asm configuration option. Affected files
2251 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2254 * Implemented the backup resuming protocol that is used to
2255 resume the primary router position in the cell after the
2256 primary router comes back online. Affected files
2257 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2258 and silcd/server_util.[ch].
2260 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Sleep two (2) seconds after sending QUIT command to server.
2263 Affected file lib/silcclient/command.c.
2265 * Assure that if outgoing data buffer is pending do not force
2266 send any data. Affected file silcd/packet_send.c.
2268 * Assure that if outgoing data buffer is pending do not force
2269 send any data. Affected file lib/silcclient/client.c.
2271 * Implemented the backup router support when the primary router
2272 goes down. The servers and routers can now use the backup
2273 router as new primary router without loosing connectivity.
2275 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2278 in the server to indicate disabled entry. All data read
2279 from the connection will be ignored and no data is sent
2280 for entry that is disabled. Affected files are
2281 silcd/idlist.h, silcd/server.c.
2283 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Created SFTP client and server test programs in the
2286 lib/silcsftp/tests directory.
2288 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Implemented memory filesystem (virtual filesystem) for
2291 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2294 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Implemented the SFTP (SSH File Transfer Protocol) to the
2297 lib/silcsftp. It includes SFTP client and SFTP server
2300 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * Moved lib/silccore/silcprotocol.[ch] to the
2303 lib/silcutil library.
2305 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2306 take variable argument list pointer as argument. Affected
2307 file lib/silcutil/silcbuffmt.[ch].
2309 * Added silc_buffer_set function that is used to set data
2310 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2311 Affected file lib/silcutil/silcbuffer.h.
2313 * Changed various routines in the core library to use the new
2314 silc_buffer_set instead of allocating new buffer only for
2317 * Added 64-bit value formatting and unformatting support to the
2318 silc_buffer_[un]format routines. Affected file is
2319 lib/silcutil/silcbuffmt.[ch].
2321 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2322 to includes/bitmove.h.
2324 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Fixed channel user mode saving in client library. Affected
2327 file lib/silcclient/command[_reply].c.
2329 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Defined the file transfer to the SILC Protocol. Added
2332 new packet type SILC_PACKET_FTP and defined File Transfer
2333 Payload. The mandatory file transfer protocol is SFTP
2334 (SSH File Transfer Protocol). Affected file in addition
2335 of the internet draft is lib/silccore/silcpacket.h.
2337 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2338 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2339 is used as part of backup router protocol when the primary
2340 router of the cell is back online and wishes to resume
2341 the position as primary router.
2343 * Redefined the MAC generation keys in the protocol. The
2344 same key is not used anymore in both direction. Both
2345 direction will now use different keys for sending and
2346 receiving. This fixes a potential security flaw. This
2347 change causes incompatibilities in the protocol.
2349 * Redefined also the MAC computation from the packet.
2350 An packet sequence number is now added to the MAC
2351 computation. This prevents possible replay attacks against
2352 the protocol. This change too causes incompatibilities
2355 Added `sequence' field to the SilcPacketContext to hold
2356 the current sequence number for the packet.
2358 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Added `created' field to the SilcIDListData in the file
2361 silcd/idlist.h to indicate the time when the entry was
2364 * Added `created' field to the SilcChannelEntry too. Affected
2365 file silcd/idlist.h.
2367 * Added `creation_time' aguments to all the announcement functions
2368 in the server. If it is provided then only the entries that
2369 was created after the provided time frame are actually
2370 announced. Affected file silcd/server.[ch].
2372 * The protocol says that the Channel ID's IP address must be
2373 based on the router's IP address. Added check for this in
2374 the silc_server_new_channel when processing incoming New Channel
2375 Payload. Affected file silcd/packet_receive.c.
2377 * Print out the correct version with --version in SILC client.
2378 Affected file irssi/src/silc/core/silc-core.c.
2380 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Fixed WHOWAS command to check for completnes of the client
2383 entry always, not just when the command is coming from client.
2384 Affected file silcd/command.c.
2386 * Added new function silc_server_packet_queue_purge to purge the
2387 outgoing data queue to the network. After the function returns
2388 it is guaranteed that the outgoing packet queue is empty.
2389 Affected file silcd/packet_send.[ch].
2391 * Purge the outgoing packet queue in the rekey protocol's final
2392 callback to assure that all rekey packets go to the network
2393 before quitting the protocol. Affected file silcd/server.c.
2395 * Added silc_client_packet_queue_parse as similar function as
2396 in server to the client library. The affected file is
2397 lib/silcclient/client.c.
2399 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Splitted silcd/server.c and created silcd/server_util.[ch]
2402 for utility functions.
2404 * Added new socket flag SILC_SF_DISABLED to indicate that the
2405 connection is open but nothing can be sent to or received from
2406 the connection. Affected file lib/silcutil/silsockconn.[ch].
2407 The checking for disabled socket is checked in the low level
2408 silc_socket_write and silc_socket_read functions.
2410 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Allow only nicknames and channel names that fits into the
2413 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2415 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * When processing JOIN command reply in server check that if
2418 the channel exists in our global list we'll move it the local
2419 list. Affected file silcd/command_reply.c.
2421 * Fixed the check whether client is joined on the channel already
2422 in JOIN command. Affected file lib/silcclient/command.c.
2424 * Fixed the JOIN command reply to check whether the channel
2425 already exists. Affected file lib/silcclient/command_reply.c.
2427 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Added silc_ske_status_string to map the SKE error numbers
2430 to readable strings. The affected files are
2431 lib/silcske/silcske[_status].[ch].
2433 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Do not show the private channels on the WHOIS channel list
2436 as it is not allowed by the protocol. The affected file is
2439 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Assure that the packet length digged from the actual packet
2442 is something sensible in the silc_packet_decrypt_rest_special
2443 in lib/silccrypt/silcpacket.c.
2445 * Free and NULL the allocated pointer in silc_hmac_alloc if
2446 the HMAC allocation fails. The affected file is
2447 lib/silccrypt/silchmac.c.
2449 * Print the selected security properties to the log files in
2450 the server. Affected file silcd/protocol.c.
2452 * Add SKE's reference counter even if calling the completion
2453 callback manually. Otherwise it goes negative, although it
2454 does not cause any problems. The affected file is
2455 lib/silcske/silcske.c.
2457 * Remove the client entry with short timeout after giving the
2458 KILL command. Affected file lib/silcclient/command.c.
2460 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2461 case all found clients are already disconnected (WHOWAS would
2462 found them) in the server. Affected file silcd/command.c.
2464 * Update the last_receive (time of last data received) to be
2465 updated only when received private or channel message so that
2466 the idle time showed in WHOIS makes more sense.
2468 * Added boolean field `valid' in to the SilcClientEntry in the
2469 client library to indicate whether the entry is valid or not.
2470 This fixes the nickname change bug on channel when changing
2471 the nickname to be same than the old (like nick to Nick) the
2472 nickname formatter doesn't set the new nick anymore to Nick@host.
2473 Affected file lib/silcclient/idlist.[ch].
2475 * Now actually fixed the nickname changing on disconnection.
2476 Added new function silc_change_nick to the Irssi SILC Client.
2477 Affected file irssi/src/silc/core/client_ops.c,
2478 irssi/src/silc/core/silc-nicklist.[ch].
2480 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Check that the public key exists in the GETKEY command before
2483 trying to encode it. Affected file silcd/command.c.
2485 * Print some notifications on received public keys with GETKEY
2486 command in the Irssi SILC Client. Affected files are
2487 irssi/src/fe-common/silc/module-formats.[ch],
2488 irssi/src/silc/core/client_ops.c.
2490 * Use IDENTIFY command to resolve the server information in the
2491 GETKEY command instead of INFO command. Affected file
2492 lib/silcclient/command.c.
2494 * All command reply functions in the client library now calls
2495 the pending command reply callbacks even if an error has
2496 occurred. The server has done this a long time and now it was
2497 time to move the client library to this as well. Now all
2498 errors can be delivered back to the pending command reply
2499 callbacks if necessary. Affected files are
2500 lib/silcclient/command[_reply].[ch].
2502 * Change the nickname on disconnection back to the username
2503 because in reconnect the server will enforce it to it anyway.
2504 Affected file irssi/src/silc/core/silc-servers.c.
2506 * Fixed a config file parsing bug in the Irssi SILC client.
2507 Affected file irssi/src/silc/core/clientconfig.c.
2509 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * When printing the channel mode on JOIN, verify that the
2512 channel key and channel's HMAC are valid. Affected file
2513 irssi/src/silc/core/client_ops.c.
2515 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2518 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2519 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2521 * Removed channel key rekey task deleting from the function
2522 silc_server_save_channel_key. Affected file silcd/server.c.
2523 Added explicit timeout task context instead that is used to
2524 delete the task if we are registering a new task before the
2525 new task has elapsed.
2527 * When channel key rekey occurs the client library now saves
2528 the old channel key for a short period of time (10 seconds) and
2529 is able to use it in case some is still sending channel
2530 messages encrypted with the old key after the rekey. Affected
2531 file lib/silcclient/[idlist.h|client_channel.c].
2533 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Added check to the silc_server_new_id_real to not accept
2536 new ID if it is the sender's own ID. Affected file is
2537 silcd/packet_receive.c.
2539 * Assure that we do not announce ourself or the one we've
2540 sending our announcements when we're router and are announcing
2541 servers to our primary router. Affected file silcd/server.c.
2543 * Fixed silc_server_command_identify_check_client to assemble
2544 correct WHOIS packet. It send corrupted WHOIS packet and
2545 caused problem with router to router connections. Affected
2546 file silcd/command.c.
2548 Fixed also silc_server_command_whois_check the same way
2549 as for the IDENTIFY command.
2551 * Added new SilcIDListStatus to the server in the SilcIDListData
2552 structure. The status now includes the current status of
2553 the entry (like registered, resolved etc.). Affected file
2554 silcd/idlist.[ch]. Defined a bunch of different status types
2555 as well. This replaced the old boolean registered field as well.
2557 Added resolve_cmd_ident field to the SilcClientEntry structure
2558 too so that if the entry is for example being resolved so
2559 another command may attach to the same pending command reply
2560 without requiring to resolve the same entry again. This concept
2561 should optimize the WHOIS and the IDENTIFY resolving under
2562 heavy load by taking away unnecessary resolving for entries
2563 that are being resolved already.
2565 Added support for adding multiple pending commands for one
2566 command idenfier. Affected file silcd/command[_reply].[ch].
2568 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2569 before deleting the data. Otherwise the hash table will have
2570 freed data in comparison functions. Affected file is
2571 silcd/command_reply.c.
2573 * Fixed silc_idlist_replace_client_id to add the new entry to
2574 the cache with NULL nickname. Otherwise there will be invalid
2575 memory as the nickname after the nickname is freed. Affected
2576 file silcd/packet_receive.c.
2578 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2579 saved into wrong slots because the previous number of entries
2580 was not taken into account. Affected file silcd/idlist.c.
2581 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2583 * If we are router and we receive JOIN notify to a channel that
2584 does not have any users then notified client is marked as the
2585 channel founder, as it is it. The affected file is
2586 silcd/packet_receive.c
2588 * Added to the extended hash table API's table_del_*ext functions
2589 the destructor as argument too, so that the caller can decide
2590 which destructor to use or whether to use destructor at all.
2591 Affected file lib/silcutil/silchashtable.[ch].
2593 * Fixed ID Cache purging. It actually deleted the entries from
2594 the hash table after the data was freed. The hash table ended
2595 up comparing freed memory. The affected file is
2596 lib/silccore/silcidcache.c.
2598 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Fixed Irssi SILC client's KILL command's HELP syntax.
2602 * The USERS command now resolves the detailed user information
2603 if the userinfo field is missing. Affected file is
2604 lib/silcclient/command_reply.c.
2606 * Do not print error in silc_file_read if the read file does
2607 not exist. Just silently return NULL. Affected file is
2608 lib/silcutil/silcutil.c.
2610 * Fixed the silc_log_output to not wine about NULL filename
2611 and to not create some bogus " " filename. Affected file is
2612 lib/silcutil/silclog.c.
2614 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Fixed various printing bugs on the user interface in the
2617 Irssi SILC Client. Minor changes that were forgotten from
2620 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Fixed the configure.in.pre and the compilation and distribution
2623 environment to support the new autoconf 2.52. That version is
2624 now required to compile the CVS trunk.
2626 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2629 to generally parse user@fqdn format strings. Affected file
2630 lib/silcutil/silcutil.c.
2632 * Added nickname_format and nickname_force_format fields to the
2633 SilcClientParams structure. The first one defines the format
2634 for the nicknames that the library will enforce if the receives
2635 multiple same nicknames. The second one is boolean value and
2636 can be used to force the library to always enforce the format
2637 to the nicknames regardles whether there are multiple nicknames
2638 or not. This configurable formatting was employed to flexibly
2639 support accessing multiple nicknames from the user interface.
2640 The userinterface can now set the nicknames to what ever format
2641 they prefer. Affected file lib/silcclient/silcapi.h.
2643 Added function silc_client_nickname_format to the file
2644 lib/silcclient/idlist.c. It performs the nickname formatting.
2646 Added new field `hostname´ to the SilcClientEntry context.
2647 It holds the hostname of the client. Affected file is
2648 lib/silcclient/idlist.h.
2650 * Irssi SILC Client sets the nicknames in nick@hostn format.
2651 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2652 irssi/src/silc/core/silc-core.c.
2654 The WHOIS printing now also shows both the real nickname and
2655 the formatted nickname so that user knows how to access the
2656 user if there are multiple same nicknames cached. Affected
2657 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2658 printing formatting too to take the hostname now as a separate
2659 argument. The Affected file is
2660 irssi/src/fe-common/silc/modules-formats.[ch].
2662 * Changed the silc_client_get_clients_local to accept the formatted
2663 nickname as argument. It accepts the real nickname too but the
2664 formatted nickname can be used to find the true entry from
2665 multiple entries. Affected file lib/silcclient/silcapi.h and
2666 lib/silcclient/idlist.c.
2668 * Added nickname_format_parse field to the SilcClientParams.
2669 It is a callback function provided by the application to parse
2670 the nickname out of the formatted nickname string. The library
2671 calls it to get the nickname from the formatted string. Since
2672 the application generally knows better the format of the nickname
2673 string it parses it instead of the library, even though library
2674 encodes the formatted string. If the callback function is not
2675 provided then the library will use the string as is. The
2676 affected file is lib/silcclient/silcapi.h.
2678 * All the nickname strings passed to the client library in
2679 commands are now expected to be formatted nickname strings.
2680 If the command does not support the formatted nickname string
2681 it will assume that the sent string is the actual nickname.
2682 Affected file lib/silcclient/command.c.
2684 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Added public key authentication support to OPER and SILCOPER
2687 commands in the client library. Affected file is
2688 lib/silcclient/command.c.
2690 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Changed the get_auth_methdod client operation to be asynchronous.
2693 It can be async if the application resolves the authentication
2694 method from the server during the negotiation. Added new
2695 SilcGetAuthMeth completion callback that the application will
2696 call after resolving the authentication method.
2698 Added function silc_client_request_authentication_method that
2699 the application can use to resolve the authentication method
2700 from the server. Added also SilcConnectionAuthRequest callback
2701 that the library will call after the server has replied. The
2702 application can call this function if it does not know the
2703 current authentication method.
2705 Affected files are lib/silcclient/client.c and
2706 lib/silcclient/silcapi.h.
2708 * The Irssi SILC client now automatically resolves the authentication
2709 method incase any configuration information is not present (and
2710 currently there never is). The affected file is
2711 irssi/src/silc/core/client_ops.c.
2713 * Fixed public key authentication from the client library.
2714 Affected file lib/silcclient/protocol.c. Changed also the
2715 protocol specification about the public key authentication in
2716 the connection authentication protocol. The actual data to be
2717 signed is now computed with a hash function before signing.
2719 * Fixed the public key authentication from the server as well.
2720 Affected file silcd/protocol.c.
2722 * Removed the mlock()'s from the memory allocation routines.
2723 Affected file lib/silcutil/silcmemory.c. The ./configure does
2724 not check anymore for the mlock(). Affected file is
2727 * Fixed USERS command in server to allow the execution of the
2728 command for private and secret channels if the client sending
2729 the command is on the channel. Affected file silcd/command.c.
2731 * Fixed silc_client_get_clients_local to return the clients
2732 count correctly. It could return wrong value. Affected file
2733 lib/silcclient/idlist.c.
2735 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2738 types. The assembler optimizations seemed not to like 64-bit
2739 data types. The assmebler optimizations thus are now enabled
2740 also for BSD systems as opposed to only enable them for Linux.
2742 * Do not check for threads at all on BSD systems. Affected
2743 file configure.in.pre.
2745 * Removed -n and -h options from the Irssi SILC Client since
2746 they are not used in silc.
2748 * Fixed the prime generation to assure that the first digit
2749 of the generated random number is not zero since our conversion
2750 routines does not like number strings that starts with zero
2751 digit. If zero digit is seen the random number is regenerated.
2752 This caused some corrupted RSA keys when the zero first digit
2753 was met. Affected file lib/silcmath/silcprimegen.c.
2755 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Fixed WIN32 configuration in the ./configure script.
2758 Fixed to include xti.h on environments that has it.
2759 Patches by Carsten Ilchmann and andrew.
2761 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Changed the silc_id_create_client_id to be collision
2764 resistant. It is now assured that there cannot be created
2765 two same client ID's. I suspect that some weird bugs in
2766 the server were actually caused by duplicate Client IDs.
2767 Affected file silcd/serverid.[ch]. A router receiving
2768 new ID now also assures and informs the sending server
2769 if the ID caused collision.
2771 * Changed the silc_id_create_channel_id to also assure that
2772 there are no collisions.
2774 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2776 * Statement about ignoring the Mutual Authentication flag when
2777 performing rekey with PFS was a bit misleading. It is ignored
2778 if it was set in the initial negotiation, it cannot be even
2779 set in the rekey. Fixed in the ke-auth draft. Started the
2780 new versions of the protocol drafts in the doc/.
2782 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2784 * Fixed a bug in silc_client_command_identify_save when saving
2785 new channel information. The channel name was no duplicated
2786 and caused crash on exit. Affected file is
2787 lib/silcclient/command_reply.c.
2789 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Fixed the getkey command handling in the server. Send just
2792 empty OK reply to the sender if the key could not be fetched
2793 (but everything else was ok, like the key just was not available).
2794 Changed the public key parameter to optional in the protocol
2795 specs so that empty OK reply can be sent. Affected file
2798 Added a message to Irssi SILC client to tell to user if the
2799 server did not return a public key.
2801 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Fixed a channel key regeneration bug. It registered new
2804 timeout tasks exponentially until all system resources were
2805 used. Affected file silcd/server.c.
2807 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Added the SILC Document generator to the scripts/silcdoc.
2810 It can be used to generate the Toolkit Reference Manual out
2811 of the source tree. Internally it will also use the RoboDoc
2812 generator now imported in util/robodoc.
2814 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * Added couple of return's in rekey protocol if error orccurred
2817 during the protocol. The execution must be terminated.
2818 Affected file silcd/protocol.c. Also, terminate the protocol
2819 always with timeout.
2821 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * The client's Client ID was created initally from the wrong
2824 nickname (it could have been in format nick@host) in the
2825 silc_server_new_client. Affected file silcd/packet_receive.c
2827 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Added some SILC_LOG_ERROR's to various error conditions
2830 if client could not be added to ID cache. Affected files
2831 silcd/packet_receive.c and silcd/server.c.
2833 * When client's sock->user_data is freed, NULL also the
2834 client->router and client->connection pointers. Added check
2835 for these pointers being NULL to various places around the
2836 code. Affected file silcd/server.c.
2838 * Added client->data.registered == TRUE checks to various
2839 places around the code to assure that unregistered client's
2840 are not handled when it is not allowed. Affected file
2843 * Added `bool registered' fields to all
2844 silc_idlist_[server|client]_get_* routines to indicate whether
2845 the fetched client needs to be registered or not. Affected
2846 file silcd/idlist.[ch].
2848 * Add your own entry as registered to the ID cache in the
2849 server. Affected file server.c.
2851 * Fixed a bug in silc_server_new_server. The SilcServer was
2852 set as the new server's context instead of SilcServerEntry.
2853 This naturally caused some weird bugs.
2855 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Do not delete the channel rekey task when adding it
2858 for in silc_server_create_channel_key.
2860 * Changed the silc_server_create_channel_key to return
2861 TRUE or FALSE to indicate the success of the channel key
2864 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Fixed MSVC++ project files and added missing files to
2867 Makefiles under win32/.
2869 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Do not add TCP_NODELAY flag if the operating system
2872 does not have it defined. Affected files are
2873 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2875 * Fixed buffer overflow from Irssi SILC Client. Affected
2876 file irssi/src/fe-common/core/themes.c.
2878 * Fixed double free in client library in the file
2879 lib/silcclient/client.c when disconnecting from server.
2881 * Applied double free patch from cras to Irssi SILC client.
2882 Affected files irssi/src/core/[modules/expandos].c
2884 * Fixed the disconnection handling to Irssi SILC Client.
2885 The application must call silc_client_close_connection
2886 in ops->connect client operation in case of failure of
2887 the connection. Affected file is
2888 irssi/src/silc/core/client_ops.c.
2890 * Do not set sock->protocol to NULL in the function
2891 silc_client_close_connection after executing the protocol's
2892 final callback since the sock might not be valid anymore.
2893 Affected file lib/silcclient/client.c.
2895 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Do not enable SILC_THREADS if the linking with libpthread
2898 did not happen. Affected file configure.in.pre.
2900 * Added notion to protocol specification that server must
2901 verify the sent authentication payload with CMODE when
2902 setting the channel founder key. Implemented it to the
2903 server. Affected file silcd/command.c.
2905 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Added _EXTRA_DIST SILC distribution variable to the
2908 distributions file. It is used to conditionally add extra
2909 files or directories to the specific distribution. Affected
2910 files ./prepare, Makefile.am.pre and distributions.
2912 Removed the `_' from the start of the distribution names.
2915 * Added README.WIN32 for instructions to compile the Toolkit
2918 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Fixed a double free in disconnection in the server. Affected
2921 file is silcd/server.c.
2923 * Fixed the lib/silcske/groups.c to work now also with GMP
2924 MP library. The string conversion did not work when using
2925 specific base and the base is indicated in the string as well.
2927 * Created win32/ directory which now includes MSVC++ specific
2928 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2929 It will appear only in the toolkit distribution
2931 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Changed the key material distribution function in case when
2934 the hash output is too short. The data is now concatenated
2935 a bit differently than it used to. Made the change to the
2936 SKE protocol specification.
2938 * Added better GMP detection to configure.in.pre. A patch
2941 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Fixed a minor bug in SKE that might cause some problem on
2944 some platforms. Affected file lib/silcske/silcske.c.
2946 * Added the cookie checking for initiator in the SKE. It checks
2947 that the responder returns the sent cookie unmodified. The
2948 affected file is lib/silcske/silcske.c. Added new SKE
2949 error type INVALID_COOKIE that can be sent during the
2950 negotiation. Fixed some memory leaks as well.
2952 * Added the "invalid cookie" error message to Irssi SILC client's
2955 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Added `task_max' field to the SilcClientParams to indicate
2958 the maximum tasks the scheduler can handle. If set to zero,
2959 default values are used. Affected file lib/silcclient/silcapi.h.
2961 * Fixed memory leaks in silc_client_close_connection. Affected
2962 file lib/silcclient/client.c.
2964 * Added silc_client_del_client_entry to client library to free
2965 all memory of given client entry. Affected file is
2966 lib/silcclient/idlist.[ch].
2968 * Added new functions silc_client_del_channel and
2969 silc_client_del_server to delete channel and server entries.
2970 Affected file lib/silcclient/[silcapi.h/idlist.c].
2972 * Removed silc_client_del_client_by_id from silcapi.h.
2974 * Fixed the INFO command to return the server's own info
2975 correctly when querying by Server ID. Affected file is
2978 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Removed the non-blocking settings in WIN32 code in the
2981 silc_sock_[read/write] and added SleepEx instead. Affected
2982 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2983 of input data is now checked with FIONREAD and ioctlsocket.
2985 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Call silc_schedule_task_del_by_context in the
2988 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2989 Affected file lib/silccore/silcprotocol.c.
2991 * Call silc_protocol_cancel for active protocols in the
2992 silc_server_close_connection if the funtion
2993 silc_server_free_sock_user_data has not been called.
2994 Affected file silcd/server.c.
2996 * Generic tasks cannot be deleted using the del_by_fd
2997 task deleting function since generic tasks does not match
2998 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3000 * Added a notion to SILCOPER help file that the SILCOPER works
3001 only on router server, not on normal server.
3003 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * Added for WIN32 support for the new scheduler as well.
3006 Affected file lib/silcutil/win32/silcwin32schedule.c.
3008 * Fixed the SHA1 implementation to work on various platforms.
3010 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3013 API. It is part of the scheduler now. Everything else is
3014 as previously but some functions has changed their names.
3015 Checkout the lib/silcutil/silcschedule.h for the interface.
3016 Updated all applications to use the new interface. Affected
3017 files are lib/silcutil/silcschedule.[ch].
3019 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Found a bug in the SKE implementation. The HASH value,
3022 specified by the protocol, was not computed correctly. The
3023 public key of the responder was not added to the computation
3024 even though it is mandatory. Affected file lib/silcske/silcske.c.
3025 This unfortunately causes incompatibilities with older
3026 clients and servers.
3028 * Added WIN32 specific network init and uninit functions:
3029 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3030 the Winsock2. Affected file lib/silcutil/silcnet.h and
3031 lib/silcutil/win32/silcwin32net.c.
3033 * Set the socket always to nonblocking mode on WIN32 after
3034 reading data or writing data. Affected file is
3035 lib/silcutil/win32/silcwin32sockconn.c.
3037 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * Fixed various compilation problems under WIN32. Affected
3040 files lib/silcutil/win32/silcwin32thread.c and
3041 lib/silcutil/win32/silcwin32schedule.c.
3043 * Removed all _internal.h #includes from public header
3044 files. Internal headers must never be included from
3047 Removed also the lib/silcske/payload_internal.h file.
3049 * All include files that may be needed (public and some others
3050 included by the public headers) by application developers are
3051 now copied to the ./includes directory. It does not copy any
3052 internal headers. Affected file Makefile.defines.pre and all
3053 Makefile.am's under lib/ and subdirs.
3055 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Do not change the ~/.silc directory's permissions automatically.
3058 Affected file irssi/src/silc/core/clientutil.c.
3060 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * Do not cancel the protocol in silc_server_close_connection
3063 it might cause recursion. Now cancelled in the function
3064 silc_server_free_sock_user_data. Affected file silcd/server.c.
3066 * Fixed the silc_server_remove_clients_by_server to regenerate
3067 the channel keys correctly finally. Added also new function
3068 silc_server_remove_clients_channels to actually do it.
3069 Affected file silcd/server.c.
3071 * Fixed the silc_server_new_channel to not crash by giving
3072 wrong router to the new channel. Affected file is
3073 silcd/packet_receive.c.
3075 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3078 which is given as argument to the silc_client_alloc now.
3079 It can be used to configure the client and set various parameters
3080 that affect the function of the client.
3082 * The USERS command in server did not check whether the channel
3083 is private or secret. Affected file silcd/command.c.
3085 * Added new argument to the USERS command in protocol specification.
3086 The USERS command now can take the channel name as argument
3087 as well. Added support for this in client and server and
3088 updated the protocol specs.
3090 * Completed the GETKEY command in client. It can be now used
3091 to fetch also servers public key not only some clients.
3092 Affected files lib/silcclient/command[_reply].c.
3094 * Added silc_client_get_server to return server entry by the
3095 server name. Affected files lib/silcclient/silcapi.h and
3098 * Redefined the IDENTIFY command in protocol specification to be
3099 more generic. It now can be used to query information about
3100 any entity in the SILC Network, including clients, servers and
3101 channels. The query may be based either the entity's name
3102 or the ID. Added support for this in both client and server.
3104 Affected files silcd/command.c and lib/silcclient/command.c
3105 and command_reply.c.
3107 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3108 the _from_client and _from_server functions. Affected file
3111 * Added silc_client_get_channel_by_id_resolve to the file
3112 lib/silcclient/silcapi.h to resolve channel information by
3113 its ID. Added also silc_client_get_channel_by_id that
3114 does not resolve it from the server.
3116 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Added SilcServerEntry context into the client library
3119 to represent one server. The INFO command now allocates
3120 these to save the resolved server info. For now on the
3121 client library will also keep information about servers,
3122 connected and resolved with INFO.
3124 The INFO command now allocates the SilcServerEntry context
3125 and saves the server info there. The COMMAND_REPLY in
3126 the INFO now returns the parameters to application in
3127 same order as defined in the protocol specification.
3129 The entries are cached in the client->server_cache.
3131 * The INFO command is now issued after received the Client ID
3132 from the server. Affected file lib/silcclient/client.c.
3134 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3135 to the application as the mode changer might be server.
3136 It is guaranteed that NULL is not returned anymore to the
3137 application. Affected file lib/silcclient/client_notify.c.
3139 The ID Type is now also passed to the application so that
3140 it can check whether the returned entry is SilcClientEntry
3143 Added new function silc_client_get_server_by_id to return
3144 the server entry by ID. Affected files are the
3145 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3147 * Do not create the channel in the Irssi SILC Client when issuing
3148 the JOIN command but when received the sucessful JOIN command
3149 reply. Otherwise the channel might get created even though we
3150 could not join it. The Affected file is
3151 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3153 * Fixed a channel joining bug in router. The router must also
3154 check the channel modes, invite and ban lists etc. when serving
3155 the JOIN command sent by normal server. Affected file is
3156 silcd/command.c. The router now resolves the client's
3157 information from the server who sent the JOIN command if it
3158 does not know it, and processes the JOIN command only after
3161 * Changed the SilcCommandCb to take new argument; void *context2.
3162 Affected file lib/silccore/silccommand.h
3164 The second argument in the command callbacks in the server now
3165 includes the SilcServerCommandReplyContext if the command was
3166 called as pending command callback from the command reply.
3167 Otherwise it is NULL. When called as pending the status of the
3168 command reply will be checked and if it was erronous the
3169 error will be sent to the original sender of the command.
3170 This way the client always receives the error messages even
3171 though the server was actually the one who received the error
3172 when it resent the command to router, for example. Affected
3173 files silcd/command[_reply].[ch].
3175 * Fixed sending WHOWAS command's error message to client if
3176 the requested client could not be found. It was missing.
3179 * Changed the CMODE and CUMODE commands reply arguments in the
3180 protocol specification. The Channel ID is now sent in both
3181 of the commands to identify the channel. Implemented this
3182 new feature to the client and server. Affected files
3183 lib/silcclient/command_reply.c and silcd/command.c.
3185 * Made better checks for invite and ban lists in the JOIN
3186 command in server. Affected file silcd/command.c.
3188 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * The server now performs the incoming host IP/DNS lookup
3191 using the silc_socket_host_lookup and thus does not block
3192 the server anymore. Affected file silcd/server.c.
3194 * Completed the multi-thread support for SILC Scheduler in
3195 the lib/silcutil/silcschedule.c.
3197 * Fixed the configure.in.pre to detect the pthread correctly
3200 * Fixed a deadlock in silc_task_queue_wakeup in the file
3201 lib/silcutil/silctask.c.
3203 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Added new function silc_schedule_wakeup that is used in
3206 multi-threaded environment to wakeup the main thread's
3207 schduler. It needs to be used when a thread adds a new task
3208 or removes a task from task queues. After waking up, the
3209 scheduler will detect the task queue changes. If threads
3210 support is not compiled in this function has no effect.
3211 Implemented the wakeup mechanism to both Unix and WIN32
3212 systems. Affected files are lib/silcutil/silcschedule.[ch],
3213 lib/silcutil/unix/silcunixschedule.c and the
3214 lib/silcutil/win32/silcwin32schedule.c.
3216 * Added new function silc_task_queue_wakeup to wakeup the
3217 scheduler by the specified task queue. Affected file
3218 lib/silcutil/silctask.[ch].
3220 * The silc_socket_host_lookup_start now wakes up the scheduler
3221 after adding the timeout task. Affected file is
3222 lib/silcutil/silcsockconn.c.
3224 * The silc_socket_host_lookup is synchronous now if the threads
3225 support is not compiled in. However, the callback is still
3226 called asyncronously through the scheduler, anyway. Affected
3227 file lib/silcutil/silcsockconn.c.
3229 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Added new function silc_socket_host_lookup to perform
3232 asynchronous IP and FQDN lookups for the socket connection.
3233 Affected files lib/silcutil/silcsockconn.[ch].
3235 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3237 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3238 that may or may not compile the mutex support in.
3240 Changed the silc_mutex_alloc interface. It allocates the
3241 mutex now to the sent pointer and returns TRUE or FALSE.
3243 Affected file lib/silcutil/silcmutex.h.
3245 * Wrote the SILC Task Queue interface to support multi-threads.
3246 Affected file lib/silcutil/silctask.[ch].
3248 * Wrote the SILC Scheduler to support multi-threads. Affected
3249 file lib/silcutil/silcschedule.c.
3251 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3253 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3254 in lib/silcutil/win32/.
3256 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * Defined SILC Mutex API and SILC Thread API and implemented
3259 them for Unix. Affected files are
3260 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3261 lib/silcutil/unix/silcunixmutex.c and
3262 lib/silcutil/unix/silcunixthread.c.
3264 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3266 * Fixed the silc_server_remove_clients_by_server's channel
3267 key re-generation. The hash table handling was incorrect
3268 and would not work with many channels. Affected file is
3271 * Fixed some memory leaks around the server code.
3273 * Rewrote the silc_server_get_users_on_channel to support IPv6
3274 based Client ID's. Affected file silcd/server.c.
3276 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3277 specification. However, a separate document must be written
3278 to define the detailed signing procedure and the payload
3279 associated with the flag. Defined the flag to the
3280 lib/silccore/silcchannel.h as well.
3282 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * Changed the dynamic tables to static size tables in the
3285 lib/silccrypt/silchmac.c.
3287 * Removed GCC dependencies from the code. A patch by cras.
3289 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Do not show the error "Error receiving packet bla bla"
3292 in server if it really was not an error (-2 means that reading
3293 is pending). Affected file silcd/server.c.
3295 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Fixed a possible crash in silc_server_remove_clients_by_server
3298 in silcd/server.c. Fixed there also some memory leaks.
3300 * Fixed the silc_idlist_replace_client_id. It could replace
3301 wrong key in the hash table. Affected file silcd/idlist.c.
3303 * Do not check whether there are global users on the channel
3304 if the channel->global_users is FALSE. Affected functions
3305 silc_server_remove_from_one_channel and
3306 silc_server_remove_from_channels in silcd/server.c. Also,
3307 do not check if the removed client is local as we can be
3308 sure that global client was not removed from the channel
3309 and checking for global users is not needed.
3311 * The silc_server_remove_clients_by_server now re-generates
3312 the channel keys correctly for those channels that had
3313 clients removed from them. Affected file silcd/server.c.
3315 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Found the reason of random crashes in the server. We weren't
3318 ignoring the SIGPIPE signal (which can be sent in write())
3319 and it crashed the server. Affected file silcd/silcd.c.
3321 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3323 * Assure that sock->user_data is not NULL in the function
3324 silc_server_packet_send in silcd/packet_send.c.
3326 * Disconnect the remote connection if it could not be added
3327 to any ID lists in the server. The affected file is
3330 * Check in silc_server_packet_send[_real/dest] that the
3331 socket is not disconnecting and ignore the data if it is.
3332 Affected file silcd/packet_send.c.
3334 * Define inline to __inline on native WIN32 compilation.
3335 Affected file includes/silcwin32.h.
3337 * Added some explicit type casts for inline code since MSVC
3338 require them. Affected files lib/silcutil/silcbuffer.h,
3339 lib/trq/silcdlist.h and lib/trq/silclist.h.
3341 * Print warning in log files from now on if the packet
3342 decryption fails. Affected file silcd/server.c.
3344 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Changed the `say' client operation's interface to accept
3347 new `type' argument to indicate the type of the message sent
3348 by the library. The application may filter the library's
3349 messages according the type. The affected file is the
3350 lib/silcclient/silcapi.h.
3352 * Added two new functions to lib/silcclient/silcapi.h:
3353 silc_client_del_client and silc_client_del_client_by_id.
3354 Affected file lib/silcclient/idlist.c.
3356 * Moved the clientincludes.h from includes/ to silc/ and
3357 serverincludes.h from includes/ to silcd/.
3359 * The modes for the CMODE and CUMODE are now passed as
3360 uint32 for application with COMMAND_REPLY. The affected
3361 file is lib/silcclient/command_reply.c.
3363 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3365 * /WHOIS without arguments shows client's own information.
3366 Affected file lib/silcclient/command.c.
3368 * Changed PING to not accept any arguments. The specs
3369 says that client can ping only the connected server so
3370 requiring an argument is not needed. Affected file is
3371 lib/silcclient/command.c.
3373 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Fixed a fatal bug in private message sending and reception
3376 encryption and decryption when using private message keys.
3377 The implementation was incorrect and did not follow the
3378 specification. It causd that some of the message were
3379 lost since it did not use the sending and receiving keys
3380 as the protocol suggests. This has been fixed and will cause
3381 incompatibilities with older clients when sending private
3382 message encrypted with private message keys. Affected files
3383 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3384 and various other in Irssi SILC Client.
3386 Added `responder' boolean argument to the functions
3387 silc_client_add_private_message_key[_ske] to indicate when
3388 the key is added as responder or initiator of the key
3391 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Removed the silc_ske_check_version function and created
3394 a SilcSKECheckVersion callback. Added also a function
3395 silc_ske_set_callbacks that is now used to set all SKE
3396 callbacks. The callback functions are not given to
3397 the SKE functions anymore, but this function is used to
3400 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3402 * Added `silc_version' argument to the silc_client_alloc
3403 to define the version of the application for the library.
3404 The library will use the version string to compare it
3405 against the remote host's (usually a server) version
3406 string. Affected file lib/silcclient/silcapi.h
3408 * Added the KE protocol context to Key Agreement context
3409 in client library so that we can abort the SKE if it
3410 is in process when we get timeout. Affected file is
3411 lib/silcclient/client_keyagr.c.
3413 * Do not resolve the client ID forever if it returns in the
3414 first time that such client does not exist. This was done
3415 for example with private message. Affected file is
3416 lib/silcclient/client_prvmsg.c.
3418 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3420 * Do not add regex.h for WIN32. The affected file
3421 includes/silcincludes.h.
3423 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3424 not work yet 100%. It generates the DLL's automatically
3425 when compiling with --with-win32 under cygwin.
3427 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3429 * lib/contrib/regex.c is not compiled on WIN32.
3431 * Added silc_net_get_socket_opt function to the
3432 lib/silcutil/silcnet.h.
3434 * Added includes/silcwin32.h for WIN32 specific includes
3437 * Do not use ptime structure or any of the posix process
3438 functions on WIN32 in lib/silccrypt/silrng.c.
3440 * Added silc_gettimeofday to provide generic function
3441 for struct timeval on all platforms. Added the function
3442 to lib/silcutil/silcutil.h.
3444 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3446 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3447 library as they clearly belong there. As a plus side we
3448 can make the actual socket connection routines platform
3451 Added also new generic function silc_socket_read and
3452 silc_socket_write (that used to be silc_packet_[read/write].
3453 The implementation of these are platform specific.
3455 * Added WIN32 specific routines of silc_socket_[read/write]
3456 to lib/silcutil/win32/silcwin32sockconn.c.
3458 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3460 * Added preliminary support for native WIN32 compilation under
3461 cygwin (using the -mno-cygwin option for GCC) to the
3462 ./configure.in.pre. The --with-win32 now prepares the
3463 compilation for native WIN32.
3465 * Rewrote the SILC Scheduler interface in the file
3466 lib/silcutil/silcschedule.h. The scheduler is now context
3467 based and does not have anymore any global static scheduler.
3468 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3469 and created lib/silcutil/win32 directory for WIN32 based
3472 * Added Unix specific network routines to the
3473 lib/silcutil/unix/silcunixnet.c and the old
3474 lib/silcutil/silcnet.c includes now only generic routines.
3476 Added WIN32 specific network routines to the
3477 lib/silcutil/win32/silcwin32net.c.
3479 * Added Unix specific utility functions from the
3480 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3482 * Added WIN32 SILC Scheduler to the file
3483 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3486 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3488 * Do not handle JOIN notify in the server if the target client
3489 is not registered (idata->registered == FALSE). The affected
3490 file is silcd/packet_receive.c.
3492 * Update the nickrec->founder in event_cumode in the Irssi SILC
3493 client. Affected file irssi/src/silc/core/silc-channels.c.
3495 * Fixed the CUMODE_CHANGE notify handling in the server when
3496 server and router are announcing their clients on channels.
3497 Now the mode changes are saved and notified correctly. The
3498 affected file is /silcd/packet_receive.c.
3500 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3501 They really did not replace the cache entry in the ID Cache.
3502 Now they do that. Affected file silcd/idlist.c.
3504 * Fixed the KICK notify handling in the Irssi SILC client to
3505 update the channel records so that the kicked client does not
3506 appear to be on the channel. The affected file is
3507 irssi/src/silc/core/silc-channels.c.
3509 * Always update the conn->current_channel when executing command
3510 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3512 * Fixed the KILL notify handling in Irssi SILC client to remove
3513 the killed client on all channels.
3515 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Fixed the silc_parse_command_line to remove extra spaces
3518 from the start and end of the arguments. Affected file is
3519 lib/silcutil/silcutil.c.
3521 * Cancel and free any active protocol in the function
3522 silc_server_close_connection. Affected file silcd/server.c.
3524 * Cancel and free any active protocol in the function
3525 silc_client_close_connction. Affected file is
3526 lib/silcclient/client.c.
3528 * Do not execute the KILL command for clients that are in
3529 history (ie. they are not in the network). Affected file is
3532 * Fixed KILL notify handling, client does not crash anymore.
3533 Affected file irssi/src/silc/core/silc-channels.c.
3535 * Reduced the default packet buffer size from 2048 to 1024 in
3536 lib/silccore/silcpacket.c.
3538 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3539 counter to the SKE context that is incresed when the SKE library
3540 performs async operation outside the library. If the outside
3541 process frees the SKE context and FREED status will be set
3542 and the library will detect after the sync operation that the
3543 libary is freed. The affected files are
3544 lib/silcske/silcske[_status].[ch].
3546 * Resolve the client entry information in the function
3547 silc_client_channel_message to assure that NULL pointer is not
3548 passed as client entry to the application. */
3550 * Fixed the task timeout calculation to assure that there is
3551 never negative timeouts. The affected file is
3552 lib/silcutil/silcschedule.c.
3554 * Fixed the channel user mode notification sending in server.
3555 It was sent point-to-point to the router (or to server by router)
3556 but it needs to be destined to a channel. The routines now
3557 supports sending the channel user mode notifys to the channels
3558 when announcing clients and channels. Affected files are
3559 silcd/server.c and silcd/packet_receive.c.
3561 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3562 It did not actually replace the old channel entry in the cache.
3563 Affected file lib/silcclient/client_notify.c.
3565 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Fixed a possible crash in silc_packet_send_prepare. It now
3568 assures always that there is enough space in the buffer and
3569 at the tail area of the buffer (for MAC).
3571 Fixed the inbound buffer reallocation in silc_packet_read.
3572 It was old code and did not handle the reallocation correctly.
3575 The affected file is lib/silccore/silcpacket.c.
3577 * Fixed buffer overflow in silc_parse_nickname in the file
3578 lib/silcutil/silcutil.c.
3580 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * make install generates new server keys only if there is not
3585 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3588 Added check that if the NOREPLY is set then we will not send
3589 the away message. This avoids infinite loop of away messages
3590 if both clients are away. The affected file is
3591 lib/silcclient/client_prvmsg.c.
3593 * Fixed client crash if /NICK was given without arguments.
3594 Affected file lib/silcclient/command.c.
3596 * Server does not send the invite list in INVITE command back
3597 to the client if the list was not altered. Added this notion
3598 to the protocol spec as well. Affected file silcd/command.c.
3600 Fixed possible crash in INVITE command by checking the
3601 value of silc_server_get_client_route command.
3603 * Fixed the INVITE notify type handling. The arguments are now
3604 taken in correct order and client does not crash. The affected
3605 file is irssi/src/silc/core/silc-channels.c.
3607 Removed the "Inviting xxx to channel" message from the
3608 client library away and let the application handle it.
3609 Affected file lib/silcclient/command.c. Added that message
3610 to Irssi SILC client's message formats.
3612 * Fixed CMODE command crash in client. It now checks the
3613 amount of arguments correctly and does not crash. The affected
3614 file is lib/silcclient/command.c.
3616 * Do not create new channel automatically in silc_channels_join
3617 but check whether the channel by that name already exists.
3618 Affected file irssi/silc/core/silc-channels.c.
3620 * Do not send the SERVER_SIGNOFF to router if the disconnected
3621 entity was the router. Affected file silcd/server.c.
3623 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3624 SILC client as it was missing from there.
3626 Added the handling of the KICK notify to the Irssi SILC client
3627 as it was missing. Added "you have been kicked" message to
3628 Irssi SILC client's message modules formats.
3630 Added the handing of the KILL notify to the Irssi SILC client
3631 as it was missing. Added the kill message module formats
3634 The affected file is irssi/src/silc/core/silc-channels.c.
3636 * The router did not save the channel mode the server announced.
3637 Affected file silcd/packet_receive.c.
3639 * Fixed a possible crash in INFO command in server. If the
3640 server did not provide the server info it crashed. Affected
3641 file silcd/command.c.
3643 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Fixed the GETKEY command in the server to check also the
3646 global list. Otherwise the GETKEY would not work correctly
3647 in normal SILC server. Affected file silcd/command.c.
3649 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Fixed GETKEY crash, it crashed if the command did not succseed.
3653 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3656 is now real and not just an macro interface to GMP.
3658 Removed the entire GMP from the source tree and imported new
3659 NSS MPI library instead. Reason for removing GMP is that it is
3660 extremely large and compiles extremely slow. The NSS MPI
3661 is only a few files and compiles in less than 10 seconds.
3662 The speed is also about the same as GMP. The MPI is imported
3663 to lib/silcmath/mpi.
3665 If the system has GMP installed we will still use the GMP.
3666 If it is not then the NSS MPI will be compiled.
3668 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Merged a long nickname (127 characters long) crash bugfix from
3671 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3673 * Merged a freed memory reference bugfix from Irssi CVS tree.
3674 Affected file irssi/src/core/commands.c.
3676 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Added the server's public key sving and verification to the
3679 server when performing the SKE. This was missing and the
3680 remote server's (or router's) public key was accepted without
3681 checking whether we have it previously or trust it at all.
3682 Affected file silcd/protocol.c.
3684 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Check in the silc_server_timeout_remote if protocol is active
3687 and make sure that the protocol's final callback is called so
3688 that all memory if freed. Affected file silcd/server.c.
3690 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * silc_server_whois_send_reply crashed the server if the nickname
3693 was 127 characters long. Affected file silcd/command.c.
3695 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Added sanity check to the silc_server_new_client. If the hostname
3698 is provided inside username then check that the provided hostname
3699 really is the same as the resolved one. If the hostname was not
3700 resolved then check it from the public key. Affected file is
3701 silcd/packet_receive.c.
3703 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3704 if the server disconnected us and the connection is not valid
3705 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3707 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3708 the library to the lib/silcutil/silcutil.[ch].
3710 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Close log file after open. Affected file
3713 lib/silcutil/silclog.c.
3715 * Check whether sock == NULL in silc_client_send_packet and return
3716 if it is. Affected file lib/silcclient/silcclient.c.
3718 * Check rec->entry == NULL in the Irssi SILC Client before
3719 sending the channel message. Affecte file is
3720 irssi/src/silc/core/silc-servers.c.
3722 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Merged a splitted window bugfix from Irssi CVS tree. The
3725 affected file is irssi/src/fe-text/textbuffer-view.c.
3727 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3728 It did not print nickname.
3730 * Improved the distributions system a bit.
3732 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3735 irssi/src/fe-text/gui-window.c.
3737 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3738 to in-active server. The affected file is
3739 irssi/src/silc/core/client_ops.c.
3741 * Resolve the client in USERS command reply if the entry does
3742 not have username resolved. The affected file is
3743 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3744 command to WHOIS command to really resolve stuff. The USERS
3745 is not used any more in any critical section so WHOIS can
3746 be used even though it might be slower than IDENTIFY.
3748 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3751 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Changed the protocol API a bit more consistent in the
3754 lib/silccore/silcprotocol.[ch].
3756 * Changed the following headers to ROBODoc format:
3758 lib/silccore/silcpayload.h
3759 lib/silccore/silcprotocol.h
3760 lib/silccore/silcsockconn.h
3762 All core library headers are now formatted.
3764 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Fixed a bug in Irssi SILC client; do not show that you are
3767 server/router operator if you really are not. Affected file is
3768 irssi/src/silc/core/client_ops.c.
3770 * Renamed silc_command_free_payload to silc_command_payload_free.
3771 Affected file lib/silccore/silccommand.h
3773 * Added silcmath.h to include the prototoypes of various routines
3774 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3777 * Changed the following headers to ROBODoc format:
3779 lib/silccore/silcchannel.h
3780 lib/silccore/silccommand.h
3781 lib/silccore/silcid.h
3782 lib/silccore/silcidcache.h
3783 lib/silccore/silcmode.h
3784 lib/silccore/silcnotify.h
3785 lib/silccore/silcpacket.h
3786 lib/silcmath/silcmath.h
3788 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Added checking to the server code not to start the server if
3791 ciphers and stuff are not configured properly. Affected files
3792 silcd/serverconfig.[h] and silcd/server.c.
3794 * Changed the layout of the header files of the public interfaces
3795 in the SILC libraries. The new layout supports ROBODoc
3796 documentation tool (and some others) so that it is easy to create
3797 a library reference manual. All the other headers and source
3798 code must still follow the CodingStyle document. Also source
3799 code must not include these ROBODoc stuffs, only the headers.
3800 Furthermore, all public interface headers must now be named
3801 by using `silc' prefix, example: silcapi.h, silccipher.h.
3802 Some files were renamed due to this. All the other headers
3803 must not be used as public interfaces. I will update the
3804 CodingStyle document later. Changed following headers, so far:
3806 lib/silcclient/silcapi.h
3807 lib/silccore/silcauth.h
3808 lib/silccore/silcprivate.h
3809 lib/silccrypt/silcdh.h
3811 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Removed silc_client_packet_send_flush from the client library
3816 as it is not needed. Affected file lib/silcclient/client.[ch].
3818 * Added printing of message of unresolved authentication method
3819 to the Irssi SILC client. Added it to the module formats.
3820 Removed the same message from the client library.
3822 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Added new distribution feature, DISTLABEL. Every distribution
3825 can define own preprocessor label that can be used in the
3826 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3827 file distributions, acconfig.h.pre and prepare.
3829 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Added Makefile.defines_int to include the actual definitions
3832 for Makefile.defines.in. Tested the new distribution system,
3833 created distributions and tested installation.
3835 * Added AWAY message printing to the Irssi SILC client. Added
3836 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3838 * Added SCONNECT command to call the SILC's CONNECT command.
3839 Cannot use CONNECT directly since Irssi uses that internally.
3840 Affected file irssi/src/silc/core/silc-servers.c.
3842 Added ACTION local command. It is same as ME command but takes
3843 the channel as mandatory argument.
3845 Rewrote some of the Irssi's help files to suite for SILC
3848 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Added Makefile.defines[.in] that should for now on be included
3851 in all Makefile.am file in the source tree. That file includes
3852 all common compilation definitions for SILC source tree.
3854 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Minor changes to the ./prepare script to change the package
3857 name according the distribution name to the configure.in.
3859 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Created new distribution system. Added file `distributions'
3862 that defines all the distributions that can be created out of
3863 the SILC source tree. The ./prepare script now reads that
3864 file to determine how to prepare the distributions. The
3865 first argument to the ./prepare is the name of the distribution
3866 and second is the version of the distribution. If given
3867 without arguments it creates the default (toolkit) distribution
3868 with the default version (defined in ./prepare).
3870 All Makefile.am files that are subject to the distributions
3871 are now named as Makefile.am.pre. These are ./Makefile.am
3872 and lib/Makefile.am. Others may be changed later.
3874 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added invite list, ban list, some key management and connection
3877 error message printing to module formats in the Irssi SILC client.
3879 * Added new silc_client_set_away_message to set the away message
3880 that is back to the person who sent private message. The
3881 affected file lib/silcclient/silcapi.h and the
3882 lib/silcclient/client_prvmsg.c.
3884 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Fixed the private message sending in the Irssi SILC client,
3887 added local command KEY to the Irssi SILC client.
3889 Added key management and key agreement message formats to the
3890 irssi/src/fe-common/silc/module-formats.[ch].
3892 Added USERS (alias WHO) printing, server/router operator
3893 indication and LIST command printing to the module formats.
3895 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Fixed channel joining notify handling, cumode notify handling
3898 from Irssi SILC client.
3900 * Added SILC specific module-formats to the Irssi SILC client so
3901 that SILC specific message hilighting, colors etc is possible.
3902 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3904 Added channel mode, channel user mode, actions, notices,
3905 whois and whowas printing to the the module-formats.c.
3907 * Fixed a bug in channel deletion in the server. The channel
3908 is not left to the cache even if the channel founder auth mode
3909 is set when there are no users anymore on the channel. Affected
3910 file silcd/server.c.
3912 * The silc_net_localhost now resolves the entire hostname including
3913 the domain name. Affected file lib/silcutil/silcnet.c.
3915 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Changed the ask_passphrase client operation to be ascynchronous.
3918 It has now a completion callback and a context that the
3919 application must call after it has got the passphrase from
3920 the user. Affected files lib/silcclient/silcapi.h,
3921 lib/silcclient/protocol.c, lib/silcclient/command.c and
3924 Added SilcAskPassphrase callback that the application calls
3925 to deliver the passphrase to the library.
3927 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3928 The public key verification and especially a certificate
3929 verification is asynchronous procedure.
3931 Added new SILC_SKE_STATUS_PENDING status to indicate the
3932 request is pending and a callback will be called to finalize
3935 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3936 indicate that remote end did not send its public key (or
3937 certificate), even though we require it. Added check for this
3938 condition in the SKE. This was a security bug, now fixed.
3940 Defined new SilcSKEVerifyCbCompletion callback that is called
3941 when the verification process is completed.
3943 The affected files lib/silcske/silcske_status.h and
3944 lib/silcske/silcske.[ch].
3946 * Changed the verify_public_key client operation to be async
3947 as well. Defined SilcVerifyPublicKey callback that is used to
3948 indicate the success of the public key verification process.
3950 Changed the server and client to use the new async client
3953 * Changed the Irssi SILC client's internal scheduler to be called
3954 twice as many times as it used to be. As a result the client
3955 should be a bit faster now. Affected file is
3956 irssi/src/silc/core/silc-core.c.
3958 * Added support to Irssi SILC client of asynchronous public key
3959 verification and passphrase inquiry. Affected file is
3960 irssi/src/silc/core/silc-core.c.
3962 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Do not say "You have left channel %s" in client library.
3965 Moved it to the application. Affected files are
3966 lib/silcclient/command.c and silc/client_ops.c.
3968 * Fixed silc_client_get_clients. Command context was not
3969 duplicated and was freed memory in the callback. Affected
3970 file lib/silcclient/idlist.c.
3972 * Do not say "you are now talking..." on JOIN command in the
3973 client library. The appliation must handle it.
3975 * Do not say ".. changed topic to" in command reply in the
3976 client libary. The application must handle it.
3978 * Fixed TOPIC command sending in the client library.
3980 * Fixed a memory leak in silc_client_command_free in the file
3981 lib/silcclient/command.c.
3983 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Imported a modified version of Irssi client to the source tree.
3986 The Irssi will be used to create a new client called
3987 Irssi SILC. Imported to irssi/.
3989 Added silc_core_init_finish function to the Irssi. Affected
3990 file irssi/configure.in.
3992 A lot changes in the Makefile.ams around the irssi tree.
3994 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Do not rehash if the new size is same as the old size of the
3997 hash table, in the silc_hash_table_rehash*. The affected file
3998 lib/silcutil/silchashtable.c.
4000 * Replaced hash_table_del_by_context calls from the server
4001 (when channel->user_list and client->channels) to the
4002 hash_table_del as it is sufficient and faster.
4004 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Added silc_hash_table_list, silc_hash_table_get and the
4007 SilcHashTableList structure to provide an alternative way to
4008 traverse the hash table. The affected files are
4009 lib/silcutil/silchashtable.[ch].
4011 * Changed the server's idlist routines to use the hash table
4012 routines to optimize the code.
4014 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Replaced the client entry's `channel' list and channel entry's
4017 `user_list' list to hash tables for optimized lookup. Changed
4018 the code to use the hash table interface around the code.
4019 Affected file lib/silcd/idlist.[ch].
4021 * Added `auto_rehash' boolean argument to the function
4022 silc_hash_table_alloc to indicate whether the hash table should
4023 auto-rehash when it thinks is appropriate time. It will
4024 increase the hash table size if the there is twice as much
4025 entries in the table than the size of the table, and will
4026 decrease the size if there are twice as less entries than
4027 the size of the table.
4029 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4033 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * silc_idcache_purge_by_context deletes the entry now by context
4036 as it is supposed to do. Affected file lib/silccore/idcache.c.
4038 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4039 client is not anymore valid (WHOWAS givens the info) and not
4040 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4042 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Removed the `data' and `data_len' arguments from the ID Cache
4045 interfaces and added `name' argument. ID Cache does not handle
4046 anymore the binary data only a names associated with given ID.
4048 * When hashing a Client ID with silc_hash_id the entire ID is
4049 not hashed anymore, instead only the hash of the Client ID is
4050 hashed. This way we can access the Client ID from the cache
4051 with Client ID but with the hash of the ID (which is a hash of
4052 the nickname) as well without any difference in performance.
4054 Added also silc_idcache_find_by_id_one_ext to do one on one
4055 searching when we have the actual ID. Added also function
4056 silc_hash_client_id_compare. The affected files are
4057 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4059 * When hashing the name associated with a ID it is always done
4060 in lowercase. This way we can access the cache without worrying
4061 about case-sensitivity, even though, for example nicknames are
4064 * Fixed a bug in server with channel message sending. It put
4065 wrong ID type as destination ID. The affected file
4066 silcd/packet_send.c.
4068 * silc_idcache_del_by_context now deletes from all hash tables
4069 by context. Affected file lib/silccore/idcache.c.
4071 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Changed the client library to use the new ID Cache interface.
4074 Changes around the source tree.
4076 * Added silc_hash_table_rehash_ext to rehash with specific
4077 hash function. Affected file lib/silcutil/silchashtable.[ch].
4079 * Added silc_hash_string_compare to compare two strings in the
4080 hash table. Affected file lib/silcutil/silcutil.[ch].
4082 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Added new function silc_idcache_del_by_context into the
4085 lib/silccore/idcache.[ch].
4087 * Changed the server's ID list routines to use the new ID Cache
4088 interface. Changes around the source tree.
4090 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Added silc_hash_table_del[_by_context]_ext functions in to the
4093 lib/silcutil/silchashtable.[ch].
4095 Removed silc_hash_table_find_all* routines and added new
4096 silc_hash_table_find_foreach to replace them.
4098 Added silc_hash_table_replace_ext function as extended
4099 replacing function. Separated the simple hash table interface
4100 from the extended hash table interface in the file
4101 lib/silcutil/silchashtable.h.
4103 * Fixed minor bugs and changed it to use some of the new
4104 hash table functions in lib/silccore/idcache.c
4106 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Added new function silc_hash_table_find_all to return all keys
4109 in the hash table by the specified key. As the hash table is
4110 collision resistant it also makes it possible to have several
4111 duplicate keys in the hash table. This function may be used to
4112 find all of the keys from the hash.
4114 Added user_context arguments to the SilcHashFunction,
4115 SilcHashCompare and SilcHashDestructor to deliver user specified
4118 Added new fuctions silc_hash_table_find[_all]_ext to do
4119 extended lookup with specified hash and compare functions and
4120 specified user contexts.
4122 Added new function silc_hash_table_add_ext to add the key
4123 with specified hash function and user context.
4125 Added new function silc_hash_table_foreach to traverse all
4126 entrys in the hash table. Added SilcHashForeach callback
4129 Added new function silc_hash_table_del_by_context to delete
4130 the entry only if the context associated with the key matches.
4132 Affected files are lib/silcutil/silchashtable.[ch].
4134 * Removed silc_hash_[server/client/channel]_id and added just
4135 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4136 silc_hash_id_compare to compare two ID's using as the hash table
4137 comparison function. Added also silc_hash_data to hash
4138 binary data and silc_hash_data_compare to compare it.
4140 * Removed silc_idlist_find_client_by_hash as it is not needed
4141 anymore. Affected file silcd/idlist.[ch].
4143 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4144 to use internally the SilcHashTable. The new ID Cache is a lot
4145 faster than the old one. Some of the ID Cache interface was also
4146 rewritten and obsolete and stupid functions were removed.
4148 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Added entry_count field to the SilcHashTable to keep the number
4151 of the entries in the table. Implemented the function
4152 silc_hash_table_rehash. Added new function
4153 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4155 Fixed a minor bug in silc_hash_table_free.
4157 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4158 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4159 into the lib/silcutil/silcutil.[ch].
4161 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Implemented a collision resistant hash table into the
4164 lib/silcutil/silchashtable[ch]. See the header and the source
4165 for the SilcHashTable API.
4167 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Merged dotconf version 1.0.2 into lib/dotconf.
4171 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Do not compile anything in lib/silcsim/* if the SIM support
4174 is not enabled. The tree should now compile without problems
4177 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Compiled the SILC under cygwin. Compiled and tested briefly
4180 without problems. More tests needed. The SIMs didn't compile
4183 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4185 * Fixed possible crash in silc_get_username in the
4186 lib/silcutil/silcutil.c.
4188 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Fixed a va_arg in silc/client_ops.c.
4192 * Oops, RC5 routines were named AES and caused some problems
4193 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4195 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Added new SilcIDIP structure into the lib/silccore/id.h and
4198 replaced the old `ip' fields from all SILC ID's to that type.
4199 This is a step towards IPv6 support.
4201 The silc_id_get_len takes now the ID as an extra argument.
4202 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4203 both IPv4 and IPv6 based ID's.
4205 The affected files are lib/silccore/id.[ch] and other files
4206 around the tree using these routines.
4208 * Removed the ID length arguments in server from various
4209 silc_server_send_notify_* routines -> they are not needed
4212 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Fixed memory leak in silc_encode_pem_file in the file
4215 lib/silcutil/silcutil.c.
4217 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Check minor version as well in the SKE. Affected files are
4220 silcd/protocol.c and lib/silcclient/protocol.c.
4222 * Added --identifier option to the server so that an identifier
4223 can be when creating the public key for the server. Affected
4224 file is silcd/silcd.c.
4226 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4227 lib/silccrypt/silcpkcs.c.
4229 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Register default ciphers and stuff when using -C option with
4232 the server. Affected file sildc/silcd.c.
4234 * Put back the servers public key filename format, it is better
4235 than the new one. For now, the client keys are saved with the
4236 new filename format. The affected file silc/client_ops.c.
4238 * Implemented the Cipher API for the rest of the ciphers that
4239 did not implement it or implemented it the wrong way.
4241 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Register default ciphers and stuff when using the -S option
4244 in the client. Affected file silc/silc.c. Same also when
4245 creating new key pair with -C option.
4247 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Fixed the silc_verify_public_key client operation function to
4250 save the public keys differently. The fingerprint is now
4251 used as filename and not the hostname. This way also the
4252 client keys are saved uniquely and not with hostnames. The
4253 affected file is silc/client_ops.c.
4255 * Trimmed the silc_hash_fingerprint function to remove extra
4256 whitespaces from the end of the fingerprint. The affected
4257 file is lib/silccrypt/silchash.c.
4261 * Added silc_cipher_register_default function to register all
4262 default ciphers. It can be used when configuration files
4263 does not exist and the application does not want any specific
4264 ciphers in any specific order.
4266 The SilcDList is now used as silc_cipher_list dynamically
4267 allocated cipher list. Removed the static list all together
4268 and now all ciphers must be allocated to the dynamic list.
4269 The silc_cipher_alloc routine was changed to check only the
4272 All silc_cipher_* routines that used to return int returns
4275 The affected files lib/silccrypt/silccrypt.[ch].
4277 * The same thing was done to silc_hash_* as for silc_cipher_*
4278 routines. Affected files lib/silccrypt/silchash.[ch].
4280 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4281 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4282 Added also silc_pkcs_[un]register[_default] functions.
4283 Removed the data_context from the PKCS API.
4285 * Added silc_hmac_register_default function to register default
4286 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4287 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4288 to unregister all hmacs at once.
4290 * Register the default ciphers, hash functions, PKCSs and HMACs
4291 if client's configuration file does not exist. The affected
4294 * The client did not load the hash functions from the SIM
4295 modules at all. Added support for this. Affected file is
4296 silc/clientconfig.c.
4298 * When decoding public key with silc_pkcs_public_key_decode, check
4299 the supported algorithm only if PKCS are registered. Affected
4300 file lib/silccrypt/silcpkcs.c. The same was done with the
4301 silc_pkcs_private_key_decode.
4303 * Fixed the SILC List routines to keep the list always in order.
4304 It used to change the list's order when traversing the list but
4305 not it preserves the order. Affected file lib/trq/silclist.h.
4307 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Added the client library to use the SilcSocketConnection's
4310 reference counter (by silc_socket_dup) to prevent the bug that
4311 the socket object may be freed underneath async operation.
4313 * The name resolv library checking fixes in the configure.in.pre.
4316 * Created new version of the protocol drafts for future
4317 development. The -03 drafts are the ones that will be changed
4318 in the trunk now and the -02 will remain as they are.
4320 * Send list of CUMODE notifys to the router when announcing
4321 the channel users to the router. Affected file silcd/server.c.
4322 If the router receiving channel founder CUMODE for a channel
4323 that already has channel founder it will send CUMODE notify
4324 to the sender to remove the channel founder rights from the
4325 announced client. Affected file silcd/packet_receive.c.
4327 * The CUMODE notify may now use Server ID as well as the entity
4328 who changes the mode. Updated protocool specs.
4330 * Updated INSTALL and README files.
4332 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * New web pages in the http://silc.pspt.fi. The pages was
4339 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Implemented the [DenyConnectin] config section in the server.
4342 Added silc_server_config_denied_conn to check whether incoming
4343 connection is denied. Affected file silcd/serverconfig.[ch].
4345 * Do not check the ports when checking the incoming configuration
4346 data if the port is 0, meaning any. Affected file is
4347 silcd/serverconfig.c.
4349 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Fixed buffer overflow in silc_string_compare in the file
4352 lib/silcutil/silcutil.c.
4354 * Fixed double free in silc_server_command_leave in the file
4357 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Fixed the version checking in the server. Affected file is
4362 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Fixed the configuration data fetching when accepting new
4365 connections in the server. Affected file silcd/server.c.
4367 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Added `sender_entry' argument to the function
4370 silc_server_packet_relay_to_channel so that we can check
4371 whether some destination actually belongs to the same route
4372 the sender belongs (ie, we must not resend the packet to the
4373 sender). Affected file silcd/packet_send.[ch].
4375 * Added `servername' field to the SilcClientEntry in the server
4376 to hold the name of the server where client is from. Affected
4377 file is silcd/idlist.h.
4379 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Moved the channel message encrypting in the router betwen
4382 router connections from silc_server_channel_message to the
4383 silc_server_packet_relay_to_channel since we want to check
4384 whether we have anybody channel before encrypting anything.
4385 Affected files silcd/packet_[receive/send].c.
4387 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Fixed the [AdminConnection] server config section to support
4390 multiple entries. Affected file silcd/serverconfig.c.
4392 * Added support into the server to check the validity of the
4393 incoming connection before executing any KE or authentication
4396 * The connection configuration is now saved to the KE and
4397 connection auth protocol contexts and not fetched anymore in
4398 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4400 * The local hosts listenning address and port is also resolved
4401 now when starting the server. We want to have the socket object
4402 to include the real address and port for the listener. Added
4403 new function silc_net_check_local_by_sock into the files
4404 lib/silcutil/silcnet.[ch].
4406 * Fixed a broadcast bug in server -> do not broadcast if we
4409 * Fixed a routing bug. Do not route broadcast packets ever.
4410 Broadcast packets must be processed always and not routed since
4411 they may be destined to some other host than yourself and thus
4412 would get routed without no good reason. Affected file is
4415 * Added function silc_server_config_is_primary_route to check
4416 whether primary router connection has been configured (a router
4417 configuration that we are initiating). If there is not, we
4418 will assume that there is only two routers in the SILC network
4419 and we will use the incoming router connection as our primary
4420 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4422 * Changed the order of the broadcasting. Broadcast _after_ the
4423 packet has been processed not before. Affected file is
4426 * Fixed a [ClientConnection] parsing bug. The port was never
4427 parsed correctly thus resulting to port 0. Affected file
4428 silcd/serverconfig.c.
4430 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4431 argument and did not set the broadcast packet flag. Affected
4432 file silcd/packet_send.c. Fixed same bug in the function
4433 silc_server_send_notify as well.
4435 * If we receive NEW_ID packet for our own ID in the server, ignore
4438 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Removed the nickname from the Private Message Payload.
4443 Updated the code and the protocol specs.
4445 * Updated protocol specs for submitting to the IETF.
4447 * Tweaked the Random Number Generator a bit. Affected file
4448 lib/silccrypt/silcrng.c. Exported a new function
4449 silc_rng_[global]_add_noise which can be used to add more
4452 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Do not parse packets with different timeout when protocol
4455 is active -> may cause problem with rekey. Affected file
4458 * When server receives signoff notify it must not create
4459 new channel key if the client is on any channels since the
4460 sender of the signoff notify will create it.
4462 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added printing of error messages during SKE protocol from the
4465 failure packet sent by server during SKE. Affected file
4468 * Removed the client's failure_callback handling with timeout
4469 and handle it immediately when received.
4471 * The SKE library returned wrong type in SUCCESS and FAILURE
4472 packets. They must be 32 bit MSB not 16 bit MSB.
4474 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Ok, rewrote the logic of the re-key and now it seems to work.
4477 I tested it on high traffic with frequent re-keys without
4478 problems. Added hmac_receive (and renamed hmac to hmac_send)
4479 in SilcClientConnection in lib/silcclient/client.h and
4480 in SilcIDListData in silcd/idlist.h. Also, removed the
4481 SilcPacketParserContext's cipher and hmac fields as they are
4482 not needed anymore and actually caused some problems when
4483 the ciphers and hmac's changed underneath the packet parser.
4485 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * If re-key protocol is active then process the incoming packets
4488 synchronously since we must assure that icoming packets encrypted
4489 with the old key is processed before the new keys is set to
4490 use. This is true other packets than for REKEY packets.
4491 Affected file silcd/server.c. The same was done to client library
4492 as well, affected file lib/silcclient/client.c.
4494 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Fixed bug in client and server to accept the force send if
4497 the packet is send from silc_[server/client]_packet_process
4498 function. Otherwise the packets are never delivered, oops.
4500 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Disable force sending of packets when REKEY protocol is active.
4503 We must assure that no packet is sent directly when rekey is
4504 performed. All packets must be sent through packet queue.
4505 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4506 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4507 function is silc_[server/client]_packet_send_real to check
4510 * Replaced the SIM paths from example config files to
4511 /usr/local/modules. Also, make install creates now
4512 /usr/local/silc/logs directory to hold all the SILC server
4515 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Made the configure.in.pre work on Solaris. Patch by salo.
4519 * Made all ciphers compatible with non-x86 machines. Defined
4520 CBC mode macros into lib/silccrypt/ciphers_def.h.
4522 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Fixed the make install.
4526 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * When MAC computation fails the silc_packet_decrypt returned 0
4529 even though it was supposed to return -1. Fixed this. The
4530 affected file is lib/silccore/silcpacket.c.
4532 * Do not replace the config files in /etc/silc (in make install)
4533 if they already exist. Affected file ./Makefile.am.
4535 * Do not send re-key packets immediately but through packet queue.
4536 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4538 * Changed silc_net_check_host_by_sock to return FALSE if the
4539 IP/DNS could not be resolved. Though, it returns the IP address
4540 now even if it could not resolve it (but returns also FALSE).
4541 Affected file lib/silcutil/silcnet.[ch].
4543 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Added silc_pkcs_decode_identifier to decode the public key's
4546 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4547 Added also silc_pkcs_free_identifier. Added also new context
4548 SilcPublicKeyIdentifier.
4550 * Added -S option to the silc client. It is used to dump the
4551 contents of the specified public key file.
4553 * Changed the PKCS api to return the public key length when
4554 setting the public key.
4556 * Fixed a fatal bug in the public and private key file loading.
4557 Affected file lib/silccrypt/silcpkcs.c.
4559 * Execute the packet parsing for client with zero (0) timeout
4560 if the protocol is active. Affected file silcd/server.c.
4562 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Made the key generation options to the silcd program. Added
4565 -C option, equivalent to client's option.
4567 * Added new [ServerKeys] config section to the server. It
4568 configures the server's public and private key.
4570 * Defined generic Public Key Payload into the protocol
4571 specification to send specific type of public keys and
4574 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4575 public key or certificate.
4577 * Implemented the GETKEY command to the server and to the
4578 client library and on user interface.
4580 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Made preliminary `make install' work.
4584 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Added SilcServerRekey context into silcd/idlist.h.
4588 * Added the PFS support as defined in the specification to the
4589 SKE protocol. Affected files lib/silcske/*.c.
4591 * Added `ske_group' field to the SilcServerRekey context to hold
4592 the number of the SKE group that is used with PFS in re-key.
4593 Affected file silcd/idlist.h.
4595 * Added PFS re-key support to the server. Affected file is
4598 * Added silc_protocol_cancel to cancel execution of the next
4599 state of the protocol. Affected file is
4600 lib/silccore/silcprotocol.[ch].
4602 * Added the re-key support with and without PFS to the client
4603 library. Re-key is performed once in an hour, by default.
4605 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4606 Added silc_client_rekey_callback and silc_client_rekey_final.
4607 Affected files are lib/silcclient/protocol.[ch] and
4608 lib/silcclient/client.[ch].
4610 * Removed the `hmac_key' and `hmac_key_len' fields from the
4611 SilcClientConnection structure; not needed. Affected file is
4612 lib/silcclient/client.h.
4616 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Do not ask whether user wants to use the negotiated private key
4619 for private messages, just use it. Affected file is
4620 silc/local_command.c.
4622 * Added `send_enc_key' and `enc_key_len' fields to the
4623 SilcIDListData structure since they are needed in the re-key
4624 phase. Affected file is silcd/idlist.[ch].
4626 * Implemented the simple re-key protocol into the server.
4627 Affected files silcd/server.c and silcd/protocol.[ch]. The
4628 re-key will be performed once in an hour, by default.
4630 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4631 Added silc_server_rekey, silc_server_rekey_callback and
4632 silc_server_rekey_final.
4634 * Removed Tunneled flag from the protocol. Updated the code
4635 and the specifications.
4637 * Adde `pfs' field to the SilcIDListData to indicate whether
4638 the PFS is to be performed in the re-key. Affected file is
4641 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4644 int64 of at least the xintXX size. If void * is less that 4
4645 bytes uint32 * will be used. Defined bool as boolean.
4647 * Changed _ALL_ unsigned long and unsigned int to uint32,
4648 unsgined short to uint16 in the source tree.
4650 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4651 not handle clients that has entry->data.registered == FALSE.
4652 They are not in the network anymore. Affected file is
4655 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Implemented the sending of the SERVER_SIGNOFF notify in the
4658 server. Affected file is silcd/server.c.
4660 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4661 Added also silc_notify_payload_encode_args into the
4662 lib/silccore/silcnotify.[ch].
4664 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4665 Affected file silcd/packet_receive.c.
4667 * Implemented the SERVER_SIGNOFF notify handling in the client
4668 library. Affected file lib/silcclient/client_notify.c. Also,
4669 implemnted the printing of the SERVER_SIGNOFF info to the
4670 application. Affected file silc/client_ops.c.
4672 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4673 if the deleting was successful. Affected file silcd/idlist.[ch].
4675 * Added support for public key authentication in the connection
4676 authentication protocol in the client library. Affected file
4677 lib/silcclient/protocol.c.
4679 * Changed the server's silc_idlist_get_clients_by_* interface
4680 to support already allocated array so that new entries may be
4681 added to pre-allocated array. Affected file silcd/idlist.[ch].
4682 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4683 and command replies.
4685 * All command reply functions in the server now calls the
4686 pending command callback even if error occured. This way the
4687 error will be delivered to the client as well. Affected files
4688 silcd/command.c and silcd/command_reply.c.
4690 * Fixed INFO command to return local server's info if no server
4691 was provided. Affected file lib/silcclient/command.c.
4693 * Removed RESTART command for good. Updated the code and the
4696 * Rewrote parts of the task system. It is a bit simpler now.
4697 Removed unsued task priorities. The affected files are
4698 lib/silcutil/silctask.[ch].
4700 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Moved the USERS printing from the library to the application.
4703 Affected files lib/silcclient/command.c and silc/client_ops.c.
4705 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Added channel key re-key support. The re-key is perfomed
4710 only by the router and is done once in an hour. Added `rekey'
4711 field to the SilcChannelEntry in the server. Affected files
4712 silcd/server.c and silcd/idlist.h.
4714 * Added silc_task_unregister_by_context into the file
4715 lib/silcutil/silctask.[ch].
4717 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Added SILC_UMODE_GONE mode to indicate when the client is not
4720 present in the SILC network. Added also support to the local
4721 command AWAY that will set this mode. Added support of showing
4722 "xxx is gone" in WHOIS command. The USERS command shows the
4723 gone status as well.
4725 * Fixed setting server and router operator privileges in the
4726 server's UMODE command. Affected file silcd/command.c.
4728 * Merged the SKE KE1 and KE2 payloads into one payload. The
4729 new KE payload is equivalent to the old KE2 payload.
4731 Cleaned up the SKE Start Payload parsing. It now uses the
4732 simple buffer unformatting to do the parsing. A lot faster
4735 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4736 to the SKE that is used to indicate whether both of the SKE
4737 parties should perform authentication. By default only the
4738 responder performs authentication. By setting this flag also
4739 the initiator must do authentication. By default it is unset
4740 since in normal SKE case, client to server connection, only
4741 the responder should do authentication. When doing SKE between
4742 two clients both should perform authentication. Updated the
4743 code and the protocol specs.
4745 * A little fix to IDENTIFY command in the server. Search the
4746 client first by hash not nickname. Affected file is
4749 * Fixed the silc_client_close_connection to support closing
4750 the client to client connections wihtout deleting too much
4751 data. Affected file lib/silcclient/client.c.
4753 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4754 are received if protocol used to be active but is not anymore
4755 the application would crash due to NULL pointer dereference.
4756 Affected files silcd/server.c and lib/silcclient/client.c.
4758 * Added `hash' field to the SilcClientConnection to include
4759 the hash function negotiated in the SKE protocol.
4761 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4762 to set the channel founder authentication data. A client can
4763 claim the founder rights later by providing the authentication
4764 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4765 This way the channel founder can regain the channel founder
4766 privileges even it is left the channel. This works only on
4767 local server and the client must be connected to the same
4768 server to be able to regain the founder rights. Updated the
4769 protocol specs accordingly.
4771 Added support to the CMODE command in the client to set the
4772 founder auth data. Read the README to see how to set it.
4774 Added support to the CUMODE command to claim the founder
4775 rights. Read the README to see how to do it.
4777 Added support for the founder authentication to the Channel
4778 Entry in the server. Affected file silcd/idlist.h.
4780 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4781 server's CMODE command. Affected file silcd/command.c.
4783 * Added the following new functions into lib/silccore/silcauth.[ch]:
4784 silc_auth_get_method and silc_auth_get_data.
4786 * The server now saves the remote hosts public key to the
4787 SilcIDListData pointer. Affected file silcd/protocol.c.
4789 * The normal server now does not remove the channel entry from
4790 the cache if the founder authentication data is set. It used
4791 to remove it if the founder was the last one on the channel on
4792 the server and left the channel. The auth data is saved and
4793 if the channel is re-joined later the old entry is used with
4794 the old auth data. Affected files silcd/command_reply.c and
4797 * Removed the `pkcs' field from the SilcIDListData structure
4798 in the server; it is not used. Affected file silcd/idlist.h.
4800 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Fixed packet processing on slow links. Partial packets were
4803 never re-processed because the incoming data buffer was cleared
4804 by the application. Application must not directly clear the
4805 sock->inbuf, the packet processing routines handle it. Fixed
4806 this in client library and in server.
4808 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Fixed the WHOIS and IDENTIFY send reply function to really
4811 check whether to send list or just one entry. Affected file
4814 * Cleaned up the LEAVE command's channel key distribution. The
4815 affected file silcd/command.c.
4817 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4818 can enforce the channel mode as well. In that case the ID
4819 includes the ID of the server. The code now enforces the
4820 mode change if the router have different mode than the server.
4822 * The notify client operation with CMODE_CHANGE notify can now
4823 return NULL client_entry pointer if the CMODE was not changed
4824 by client. Application must check for this.
4826 * Added <Server ID> argument to INFO command to support server
4827 info fetching by Server ID.
4829 * Added silc_server_announce_get_channel_users to get assembled
4830 packets of channel users of the specified channel. Affected
4831 file silcd/server.[ch].
4833 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4834 was freed underneath the ID Cache.
4836 * Re-announce clients when the server received CHANNEL_CHANGE
4837 notify from the router. Affected file silcd/packet_send.c.
4839 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4842 crashed since it did not handle the fact that there is no cipher
4843 called "3" and didn't check the error condition. Now fixed.
4845 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4846 flag. It can be used to send message requests.
4848 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Implemented the RESTART command in the client.
4852 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4853 notice type messages. Added notice printing to the user
4856 * The channel keys are not re-generated if the channel's mode
4857 is PRIVKEY, ie private key on the channel exists. Affected
4858 files silcd/server.c and silcd/command.c.
4860 * Fixed a little bug in channel message delivery when channel
4861 private keys are set in the server. Affected file is
4862 silcd/packet_send.c.
4864 * Changed the setting on channel->on_channel = TRUE from the
4865 silc_client_save_channel_key to the JOIN command reply. The
4866 key payload is not received if the private channel key is set.
4867 Affected file lib/silcclient/command_reply.c and the
4868 lib/silcclient/client_channel.c.
4870 * When the CMODE_CHANGE notify is sent and the channel private
4871 key mode is removed the channel key must be re-generated in
4872 other cells as well. Added this support for the router in the
4873 silcd/packet_receive.c.
4875 * Added new local command NOTICE to send notice message on
4876 channel. Affected file silc/local_command.[ch].
4878 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added new local command ME to the client. It is used to send
4881 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4882 some action. Affected file silc/local_command.[ch].
4884 * Changed channel_message and private_message client operations
4885 to deliver the message flags to the application. Added also
4886 the `flags' arguments to the silc_client_send_channel_message
4887 and silc_client_send_private_message functions. Affected file
4890 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Redefined the Private Message Payload to support private message
4893 keys and to support the new private message flags. Updated
4894 the protocol specs. Flags makes it possible to have for example
4895 CTCP style messages.
4897 * Added new type SilcPrivateMessagePayload and defined an API
4898 for it in the lib/silcclient/silcprivate.[ch].
4900 * Tested private message private keys successfully. Tested the
4901 private message key set, unset and list commands with the new
4904 * Redefined the Channel Message Payload to include the channel
4905 message flags (equal with private message flags) to support
4906 for example CTCP style messages.
4908 * Defined some of the message (for channel and private message)
4909 flags. Updated the protocol specs and added the flags to the
4910 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4912 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Added SilcKeyAgreementStatus type to the key agreement routines
4915 to indicate the current status and error if one occured.
4916 The status types are defined in the lib/silcclient/silcapi.h.
4918 * Added new local command KEY that is used to set and unset private
4919 keys for channels, set and unset private keys for private messages
4920 with remote clients and to send key agreement requests and
4921 negotiate the key agreement protocol with remote client. The
4922 key agreement is supported only to negotiate private message keys,
4923 it currently cannot be used to negotiate private keys for channels,
4924 as it is not convenient for that purpose.
4926 * Fixed a minor pending callback setting bug in the function
4927 silc_client_get_client_by_id_resolve, now the function works.
4928 Affected file lib/silcclient/idlist.c.
4930 * Added function silc_net_get_local_port to get local bound
4931 port by socket. Added to lib/silcutil/silcnet.[ch].
4933 * Added `sockets' and `sockets_count' fields to the SilcClient
4934 object. They hold the sockets of the listenning sockets in
4935 the client. Listenning sockets may be for example the key
4936 agreement server. Affected file lib/silcclient/client.[ch].
4937 Added functions the silc_client_add_socket and the
4938 silc_client_del_socket. They are exported to the application
4941 * Added ~./silc/clientkeys to support other client's public keys.
4943 * Renamed verify_server_key client operation to verify_public_key
4944 and added one argument to indicate the type of the connection
4945 (server, client etc.).
4947 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Added silc_server_connection_auth_request to handle the
4950 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4951 silcd/packet_receive.[ch].
4953 * Added silc_server_send_connection_auth_request into the
4954 silcd/packet_send.c to send the connection auth request packet.
4956 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4959 * Fixed the public key authentication in responder side in the
4960 server. The `auth_data' pointer includes the SilcPublicKey
4961 not the path to the public key. Affected file silcd/protocol.c.
4963 * Implemented the public key authentication in the initiator side
4964 in the server. Affected file silcd/protocol.c.
4966 * Removed the [RedirectClient] config section from the server
4967 configuration. Is not needed and I don't want to implement it.
4969 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Cleaned up the CMODE command in the server. It now works
4972 correctly and supports all the modes defined in the protocol.
4973 Affected file is silcd/command.c.
4975 * Added `hmac_name' field to the SilcChannelEntry in the server
4976 to hold the default HMAC of the channel. It can be set when
4977 creating the channel (with JOIN command). Affected files
4980 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4981 type to indicate the change of the current cipher and hmac
4982 on the channel. Client can safely ignore the <cipher> argument
4983 (if it chooses to do so) since the CHANNEL_KEY packet will
4984 force the channel key change anyway. The <hmac> argument is
4985 important since the client is responsible of setting the new
4986 HMAC and the hmac key into use.
4988 * Fixed the CMODE command in the client library as well.
4990 * Tested CMODE command in router environment successfully.
4992 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Show the version of the remote client (or server) when connecting
4995 to the server. It is logged to the log file. Affected file
4996 is silcd/protocol.c.
4998 * Fixed the KILLED notify handling in the client library. The
4999 client must be removed from all channels when receiving the
5002 Also, do not remove the client entry when giving the KILL
5003 command but when the KILLED notify is received.
5005 * Removed silc_idlist_find_client_by_nickname from the server.
5006 Not needed anymore. Affected files silcd/idlist.[ch].
5008 * Implemented the CHANNEL_CHANGE notify type handling to the
5009 server. Affected file silcd/server.c.
5013 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Added silc_server_send_notify_invite to send the INVITE
5016 notify between routers.
5018 * Implemented the INVITE command correctly to the server.
5020 * Implemented the INVITE notify type handling in the server.
5022 * Implemented the INVITE command to the client library and on the
5025 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Added function silc_server_get_client_resolve to find the
5028 client entry by ID from all ID lists and then resolve it
5029 (using WHOIS) if it cannot be found. Affected file is
5032 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Implemented the BAN command to the client library.
5036 * The JOIN command in the server now checks the invite list
5039 * Changed the silc_command_reply_payload_encode_va and the
5040 silc_command_payload_encode_va to support that if argument is
5041 NULL it ignores and checks the next argument. Affected file
5042 lib/silccore/silccommand.c.
5044 * Added silc_server_send_notify_ban to send the BAN notify
5045 type between routers.
5047 * Chaned the silc_notify_payload_encode to support that if
5048 argument is NULL it ignores and checks the next argument.
5049 Affected file lib/silccore/silcnotify.c.
5051 * Tested ban lists in router environment successfully.
5053 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Implemented BAN command to the server, in silcd/command.[ch].
5057 * Removed the BAN and INVITE_LIST modes from the CMODE command
5060 * Added function silc_string_match to regex match two strings.
5061 Affected files lib/silcutil/silcutil.[ch].
5063 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Redefined parts of the SilcChannelEntry in the server to support
5066 the new ban and invite lists.
5068 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Redefined the INVITE command. The same command can be used to
5071 invite individuals to the channel but also to manage the invite
5072 list of the channel (to add to and remove from the invite list).
5073 Updated the protocol specs.
5075 * Added new command SILC_COMMAND_BAN that can be used to manage
5076 the ban list of the channel. Updated the protocol specs.
5078 * Removed the channel modes: the SILC_CMODE_BAN and the
5079 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5080 in the CMODE command. The equivalent features are now available
5081 using INVITE and BAN commands. Updated the protocol specs.
5083 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5084 in the network about change in the current ban list. The notify
5085 type is not used by the client.
5087 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5088 support the invite lists.
5090 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Added new function silc_string_regexify that converts string
5093 including wildcard characters into regex string that can
5094 be used by the GNU regex library. Added into the file
5095 lib/silcutil/silcutil.[ch].
5097 Added silc_string_regex_combine to combine to regex strings
5098 into one so that they can be used as one regex string by
5099 the GNU regex library. Added into the file
5100 lib/silcutil/silcutil.[ch].
5102 Added silc_string_regex_match to match two strings. It returns
5103 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5105 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Imported GNU regex to the soruce tree into lib/contrib.
5108 Fixed some compiler warning from the regex.c.
5110 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Fixed MOTD command in the server to work in router environment.
5114 * Fixed the MOTD command in the client library to support
5115 the server argument in the command.
5117 * Added `nickname_len' argument to the silc_idlist_add_client
5118 in the server, as the `nickname' argument may be binary data
5121 * Added silc_idlist_get_channels to return all channels from
5124 * Implemented LIST command to the server. Affected file is
5127 * Implemented the LIST command to the client library and on the
5130 * Added [<user count>] argument to the LIST command reply.
5131 With private channels the user count is not shown.
5133 * Updated TODO and README.
5135 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * The client entry's data.registered must be TRUE even with
5138 global client entry on global client list. The data.registered
5139 is used to check whether the client is anymore in the network,
5140 for example with WHOWAS command so it must be valid.
5142 * Fixed the WHOWAS command in the server. It now actually works
5143 in router environment. Added function into silcd/command_reply.c
5144 silc_server_command_reply_whowas_save.
5146 * Added silc_idlist_purge function to the silcd/idlist.c
5147 to periodically purge the ID Cache.
5149 * Fixed INFO command in the server. It works now in router
5150 environment. Added <server name> argument to the INFO command
5151 reply. Updated the protocol specs.
5153 * Fixed minor bug in silc_idcache_purge to not purge if the
5154 expire value is zero.
5156 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5157 they were buggy because of the WHOWAS information.
5159 * Fixed local command MSG to handle the async resolving of
5160 the remote client properly. It used to fail the first MSG.
5161 Affected file silc/local_command.c.
5163 * Added `data_len' field to SilcIDCache context.
5165 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Update TODO. Todo in commands in the server.
5169 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5172 used by routers as broadcast packet to inform other routers
5173 about the changed user mode.
5175 Implemented the notify handling in the server. Affected file is
5176 silcd/packet_receive.c. Added the function
5177 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5179 * Added new generic Channel Payload and deprecated the New Channel
5180 Payload. The New Channel Payload is now the generic Channel
5183 * Added new argument `mode' to the silc_server_send_new_channel
5184 as it is required in the Channel Payload now.
5186 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5187 and created a new and real SilChannelPayload to represent the
5188 new generic Channel Payload. Implemented the encode/decode
5189 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5191 * Added silc_server_get_client_channel_list to return the list
5192 of channels the client has joined for WHOIS command reply.
5193 Affected file silcd/server.[ch].
5195 * Implemented the channel list sending in the WHOIS command reply
5196 in server and in the client.
5198 Implemented the channel list displaying on the user interface
5199 as well. Affected file silc/client_ops.c.
5201 * Added silc_channel_payload_parse_list to parse list of Channel
5202 Payloads. It returns SilcDList list of SilcChannelPayloads.
5203 Client for example can use this function to parse the list of
5204 channels it receives in the WHOIS command reply. The caller
5205 must free the list by calling silc_channel_payload_list_free.
5206 Affected files lib/silccore/silcchannel.[ch].
5208 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Added one new argument <user mode> to the WHOIS command reply
5211 to return the mode of the user in SILC. Updated the protocol
5214 Implemented it to the server and client.
5216 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Fixed the mode printing on the user interface on joining.
5219 Affected file silc/client_ops.c.
5221 * Implemented the UMODE command and user modes in general to the
5222 client library and to the user interface.
5224 * Implemented the UMODE command to the server.
5226 * The server now sends UNKNOWN_COMMAND error status if client sends
5227 unknown command. Affected file silcd/command.c.
5229 * All server commands now handle the command identifier the right
5230 way when sending the command reply to the client. The client can
5231 use to identify the command replies with the identifier.
5233 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Added silc_server_get_client_route to resolve the route to
5236 the client indicated by the client ID. Affected file is
5239 * Added silc_server_relay_packet as general function to relay
5240 packet to arbitrary destination. This deprecates functions
5241 like _send_private_message_key, _relay_notify etc. Affected
5242 file is silcd/packet_send.[ch].
5244 Removed silc_server_send_key_agreement,
5245 silc_server_send_private_message_key and
5246 silc_server_packet_relay_notify functions from the file
5247 silcd/packet_send.[ch].
5251 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5252 server. Affected file silcd/packet_receive.[ch].
5254 * Implemented the KILL command to the client. Implemented the
5255 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5256 Affected files lib/silcclient/command[_reply].c and
5257 lib/silcclient/client_notify.c. Implemented the KILL notify
5258 printing in the user inteface.
5260 * Fixed a lot silc_parse_nick memory leaks from the client
5261 library in the file lib/silcclient/command.c.
5263 * Changed the silc_server_send_notify_on_channels's `sender'
5264 argument from SilcSocketConnection to SilcClientEntry to
5265 check the sender as entry and not as connection object and not
5266 to send to the client provided as argument. The affected file
5267 is silcd/packet_send.[ch].
5269 * The notify packets that are destined directly to the client used
5270 to not to be processed by the server. Now changed that and the
5271 server processes all notify packets. After relaying the packet
5272 to the client the notify packet is processed in the server.
5274 * The silc_server_free_client_data now checks whether there is
5275 pending outgoing traffic for the client and purges the data to
5276 the network before removing the client entry.
5278 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5281 an client is killed from the SILC Network. Updated the protocol
5284 Added new function silc_server_send_notify_killed to the
5285 silcd/packet_send.[ch].
5287 * Added function silc_server_packet_relay_notify to relay notify
5288 packets that are destined directly to a client. In this case
5289 the server does not process the notify packets but merely relays
5290 it to the client. Affected file silcd/packet_send.[ch].
5292 Added also silc_server_packet_process_relay_notify to check
5293 whereto relay the notify. Affected file is
5294 silcd/packet_receive.[ch].
5296 * Implemented the KILL command to the server.
5300 * Added the backup schema desgined last fall to the protocol
5301 specs for everyone to see. The specification is in the
5302 *-spec-xx.txt draft and the packet type definitions for the
5303 backup routers is in *-pp-xx.txt draft. Thusly, added also
5304 new packet type SILC_PACKET_CELL_ROUTERS.
5306 * A big security problem in the implementation discovered. The
5307 signoff of an client did not cause new channel key generation
5308 which it of course should've done. The channel keys must be
5309 always re-generated when client leaves (or signoffs) the channel.
5310 The silc_server_remove_from_channels funtion now handles
5311 the channel key re-generation.
5313 * Added `sender' argument to the silc_server_send_notify_on_channels
5314 to not to send the client provided as argument. Affected file
5315 silcd/packet_send.[ch].
5317 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Implemented OPER and SILCOPER commands into the server and
5322 * Added silc_auth_verify and silc_auth_verify_data to verify
5323 the authentication directly from the authentication payload.
5324 It supports verifying both passphrase and public key based
5325 authentication. Affected file lib/silccore/silcauth.[ch].
5327 * Added `hash' field to the SilcIDListData structure. It is the
5328 hash negotiated in the SKE protocol. Affected file is
5331 * Slight redesigning of the SilcAuthPayload handling routines.
5332 Do not send SilcPKCS but SilcPublicKey as argument.
5334 * Implemented the public key authentication support to the
5335 serverconfig. The public key is loaded from the provided path
5336 and saved as authentication data to void * pointer. Thus,
5337 changed the unsigned char *auth_data to void *auth_data;
5339 * Fixed SHUTDOWN command to send the reply before the server
5340 is shutdown. :) Affected file silcd/command.c.
5342 * Fixed fatal bug in CONNECT command. The hostname was invalid
5343 memory and server crashed. Affected file silcd/command.c.
5345 * Fixed fatal bug in CLOSE command. The server_entry became
5346 invalid but was referenced later in the command. Affected file
5349 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Fixed fatal bug in failure packet handling. Server ignored
5352 the failure and thus crashed when it came.
5356 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5359 that the command may be executed only once in (about) 2 seconds.
5360 The old SILC_CF_LAG flag is same but allows command bursts up
5361 to five before limiting.
5363 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5364 server code. Various commands now includes the CF_LAG_STRICT
5365 flag to disallow any kind of miss-use of the command.
5367 * Fixed the silc_buffer_unformat to not to allocate any data
5368 if the length of the data is zero. It used to allocate the
5369 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5371 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Changed the format of AdminConnection configuration section
5374 in the server. Added username of the admin to the format.
5375 Affected files silcd/serverconfig.[ch].
5377 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5378 to return admin configuration data by host, username and/or
5381 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Implemented WHOWAS command to the server. Added the functions:
5385 silc_server_command_whowas_parse,
5386 silc_server_command_whowas_send_reply,
5387 silc_server_command_whowas_from_client and
5388 silc_server_command_whowas_from_server
5390 * Added <Client ID> argument to the WHOWAS command reply. Updated
5391 the protocol specs accordingly.
5393 * Implemented WHOWAS command and command_reply to the client
5396 Implemented the WHOWAS printing on the user interface.
5398 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Added new argument to the WHOWAS command reply, the real name.
5401 It is an optional argument. Updated the protocol specs.
5403 * Added SilcIDCacheDestructor callback that is registered when
5404 the SilcIDCache is allocated. The callback is called when
5405 an cache entry in the ID Cache expires, or is purged from the
5406 cache. Added into lib/silccore/idcache.[ch].
5408 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5409 to destruct the client entries when the cache entry expires.
5410 Other ID Cache's in server and in the client library ignores
5413 * If the ID Cache entry's `expire' field is zero then the entry
5414 never expires. Added boolean `expire' argument to the
5415 silc_idcache_add function in the lib/silccore/idcache.[ch].
5416 If it is TRUE the default expiry value is used.
5418 * Added silc_server_free_client_data_timeout that is registered
5419 when client disconnects. By default for 5 minutes we preserve
5420 the client entry for history - for WHOWAS command.
5422 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added support to the server to enforce that commands are not
5425 executed more than once in 2 seconds. If server receives
5426 commands from client more frequently, timeout is registered
5427 to process the commands. Affected file silcd/command.c.
5428 Added new function silc_server_command_process_timeout.
5430 * Changed NICK_NOTIFY handling in client library to check that
5431 if the client's nickname was changed, so there is no need to
5432 resolve anything from the server.
5434 * Removed error printing from the WHOIS and IDENTIFY commands.
5435 If error occurs then it is ignored silently in the client library.
5436 The application, however, may map the received error to
5437 human readable error string. The application currently maps
5438 the NO_SUCH_NICKNAME error to string.
5440 * Made the command status message public to the application. Moved
5441 them from lib/silcclient/command_reply.c to
5442 lib/silcclient/command_reply.h. The application can map the
5443 received command status to the string with the
5444 silc_client_command_status_message function.
5446 * Added check to the server to check that client's ID is same
5447 as the Source ID in the packet the client sent. They must
5450 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added dist-bzip hook to the Makefile.am to make bzip2
5453 compressed distributions.
5455 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Server now enforces the maximum length for the nickname and
5458 the channel as protocol specification dictates. 128 bytes for
5459 nickname and 256 bytes for channel name.
5461 * Moved the WHOIS printing to the application. The client libary
5462 does not print out the WHOIS information anymore, the application
5463 must do it. Renamed silc_client_command_reply_whois_print to
5464 the silc_client_command_reply_whois_save.
5466 The client's idle time is also sent to the application now, and
5467 the idle is shown on screen.
5469 * Added silc_client_command_reply_identify_save to save the
5470 received IDENTIFY entries.
5472 * Do not check for channel private keys in message sending and
5473 reception if the channel does not have the PRIVKEY mode set.
5474 Affected file lib/silclient/client_channel.c.
5476 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5479 just surfaced after chaning the JOIN procedure.
5481 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Added silc_client_get_clients_by_list to get client entries
5484 from Client ID list, that is returned for example by JOIN
5485 and USERS command replies. The application should use this
5486 function for example when JOIN command reply is received to
5487 resolve the clients already on the channel (library does not
5488 do that anymore as USERS command reply is not used in the JOIN
5489 procedure anymore). Affected files lib/silcclient/silcapi.h and
5490 lib/silcclient/idlist.c.
5492 * JOIN command reply and USERS command reply returns now SilcBuffer
5493 pointers instead of unsigned char pointers when returning
5494 the client list and mode list.
5496 * Added <Client ID> argument to the JOIN command reply, mainly
5497 for the server to identify for which client the command was
5498 originally sent. Updated protocol specs accordingly.
5500 * Added SilcDlist private_key pointer to the SilcChannelEntry
5501 in the client to support the channel private keys. Affected
5502 file is lib/silcclient/idlist.h.
5504 * Added SilcChannelPrivateKey argument to the function
5505 silc_client_send_channel_message so that application can choose
5506 to use specific private ke if it wants to. If it is not provided,
5507 the normal channel key is used, unless private keys are set.
5508 In this case the first (key that was added first) is used
5509 as the encryption key.
5511 * Implemented the support for channel private key handling.
5512 Implemented the following functions:
5514 silc_client_add_channel_private_key,
5515 silc_client_del_channel_private_keys,
5516 silc_client_del_channel_private_key,
5517 silc_client_list_channel_private_keys and
5518 silc_client_free_channel_private_keys
5520 Affected file lib/silcclient/client_channel.c.
5522 * Added the support for the private keys in the channel message
5523 sending and encryption and in the message reception and
5524 decryption. Affected funtions are
5525 silc_client_send_channel_message and silc_client_channel_message.
5527 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Added SKE's key verify callback to the client library's
5530 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5532 * Removed the statement that server (or router) must send USERS
5533 command reply when joining to the channel so that the client
5534 knows who are on the channel. Instead, the client list and
5535 client's mode list is now sent in the JOIN command reply to the
5536 client who joined channel. This is better solution.
5538 * Added function silc_server_get_users_on_channel and function
5539 silc_server_save_users_on_channel to the silcd/server.[ch].
5541 * Removed function silc_server_command_send_users from the
5544 * Do not show topic on the client library anymore. The topic is
5545 sent in the command reply notify to the application and the
5546 application must show the topic now.
5548 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Added client searching by nickname hash into the IDENTIFY and
5551 WHOIS commands in the server as they were clearly missing from
5552 them. Affected file is silcd/command.c.
5554 * Fixed a bug in private message receiving in the client library.
5555 The remote ID was freed and it wasn't supposed, now it is
5558 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Minor fix to the channel payload; allocate the data area, as it
5561 needs to be of specific length.
5563 * If the key agreement port is zero then the operating
5564 system will define the bound port. Affected files are
5565 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5567 * Added new function silc_channel_payload_decrypt into the file
5568 lib/silccore/silcchannel.[ch].
5570 * Moved the channel message etc, check from silc_packet_decrypt
5571 to applications. The library calls now a generic
5572 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5573 when the packet is either normal or special. This was done to
5574 allow more wide range of checking that was not allowed when
5575 the code was in library. Now applications can do virtually any
5576 checks to the packet and return to the library the decision how
5577 the packet should be processed. Affected files are
5578 lib/silccore/silcpacket.[ch].
5580 Added silc_server_packet_decrypt_check to the server and
5581 silc_client_packet_decrypt_check to the client library.
5583 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5584 to send with specified source and destination information.
5586 * Channel message delivery between routers was broken after the
5587 channel key distribution was fixed earlier. The channel key
5588 was used be to distributed to other routers as well which is not
5589 allowed by the protocol. Now this is fixed and channel keys
5590 really are cell specific and the channel message delivery between
5591 routers comply with the protocol specification.
5593 * Fixed various commands in server to check also the global list
5594 for the channel entry and not just the local list. The affected
5595 file silcd/command.c.
5597 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Added assert()s to buffer formatting and unformatting routines
5600 to assert (if --enable-debug) when error occurs. Affected
5601 file: lib/silcutil/silcbuffmt.c.
5603 * Changed to auto-reconnect to check whether the remote host is
5604 router and register the re-connect timeout if it is. It used
5605 to check that whether we are normal server, but router must do
5606 auto-reconnect with another router as well. Affected file
5609 * Removed the [<key len>] option from CMODE command as the cipher
5610 name decides the key length, nowadays. See the defined ciphers
5611 from the protocol specification.
5613 * Added [<hmac>] option to the CMODE command to define the HMAC
5614 for the channel. Added SILC_CMODE_HMAC channel mode.
5616 * Added [<hmac>] option for the JOIN command so that user can
5617 select which HMAC is used to compute the MACs of the channel
5620 * Added Hmac field to the Channel Message Payload. The integrity
5621 of plaintext channel messages are now protected by computing
5622 MAC of the message and attaching the MAC to the payload. The
5623 MAC is encrypted. Now, it is clear that this causes some
5624 overhead to the size of the packet but rationale for this is that
5625 now the receiver can verify whether the channel message decrypted
5626 correctly and also when private keys are set for the channel the
5627 receiver can decrypt the packet with several keys and check from
5628 the MAC which key decrypted the message correctly.
5630 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5631 lib/silccrypt/silccipher.[ch].
5633 * Added silc_hash_len to return the digest length into the
5634 lib/silcrypt/silchash.[ch].
5636 * Rewrote parts of Silc Channel Payload interface in the
5637 lib/silccore/silcchannel.[ch]. The encode function now also
5638 encrypts the packet and parse function decrypts it.
5640 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Fixed a minor formatting bug in the SKE's key material processing.
5643 It actually might have processed the keys wrong way resulting
5646 * Redefined the mandatory HMAC algorithms and added new algorithms.
5647 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5648 and hmac-md5 truncated to 96 bits. The mandatory is now
5649 hmac-sha1-96. Rest are optional (including the one that used
5650 to be mandatory). Rationale for this is that the truncated HMAC
5651 length is sufficient from security point of view and can actually
5652 make the attack against the HMAC harder. Also, the truncated
5653 HMAC causes less overhead to the packets. See the RFC2104 for
5656 * Added new [hmac] configuration section. The SKE used to use
5657 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5658 is of course wrong. The official names that must be proposed in
5659 the SKE are the ones defined in the protocol specification
5660 (hmac-sha1-96 for example). The user can configure any hmac
5661 using any hash function configured in the [hash] section. At
5662 least, the mandatory must be configured.
5664 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5666 * Added HMAC list to the SKE proposal list. It has now both
5667 hash algorithm list and HMAC list. This makes the protocol
5668 incompatible with previous versions. The SKE now seems to work
5669 the way it is supposed to work, for the first time actually.
5671 * Defined plain Hash algorithms to the protocol specification.
5674 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Implemented support for key agreement packets into the server.
5677 Added functions silc_server_key_agreement and
5678 silc_server_send_key_agreement. Other than these functions,
5679 server has nothing to do with this packet.
5681 * Added support for private message key packets into the server.
5682 Added functions silc_server_private_message_key and
5683 silc_server_send_private_message_key.
5687 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5688 called in the protocol's final callback instead in the END
5689 protocol state. This makes a little more sense and in the same
5690 time in client we can use the same protocol routines for normal
5691 key exchange and to key agreement packet handling as well.
5693 * Added to both client's and server's KE protocol context the
5694 SilcSKEKeyMaterial pointer to save the key material. We will
5695 bring the key material to the protocol's final callback by doing
5696 this. The final callback must free the key material.
5698 * Added SKE's packet_send callback into client's KE protocol
5699 context so that the caller can choose what packet sending function
5700 is used. This way we can use different packet sending when
5701 doing normal SKE when doing key agreement packet handling (in
5702 the key agreement packet handling we do not want to encrypt
5705 * Implemented the responder side of the key agreement routines
5706 in the client. The client can now bind to specified port and
5707 accept incoming key negotiation. The key material is passed
5708 to the application after the protocol is over.
5710 * Implemented the processing of incoming Key Agreement packet
5711 in the client. Added function silc_client_key_agreement to
5714 * Implemented the intiator side of the key agreement routines
5715 in the client. The client can now initiate key agreement with
5716 another remote client. The key material is passed to the
5717 application after the protocol is over.
5719 * Created client_keyagr.c to include all the key agreement
5722 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5723 SILC_TASK_CALLBACK except that it is not static.
5725 * Created client_notify.c and moved the Notify packet handling
5726 from the client.[ch] into that file.
5728 * Created client_prvmsg.c and moved all private message and
5729 private message key routines from the client.[ch] into that file.
5731 * Create client_channel.c and moved all channel message and
5732 channel private key routines from the client.[ch] into that file.
5734 * Changed silc_client_get_client_by_id_resolve to resolve with
5735 WHOIS command instead of IDENTIFY command, in the file
5736 lib/silclient/idlist.c.
5738 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Implemented the SKE's responder side to the Client library.
5742 * When FAILURE is received to the protocol do not trust it
5743 blindly. Register a timeout to wait whether the remote closes
5744 the connection as it should do it, only after that process the
5745 actual failure. This was changed to both client and server.
5747 * Added client_internal.h to include some of the structures
5748 there instead of client.h in lib/silcclient/.
5750 * Added function silc_task_unregister_by_callback to unregister
5751 timeouts by the callback function.
5753 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Some "Incomplete WHOIS info" errors has been appearing on the
5756 log files. Took away the entry->userinfo check from WHOIS
5757 reply sending. The entry->userinfo is now " " if client did not
5758 provide one. I thought this was fixed earlier but something
5759 is wrong still. Let's see if the error still appears.
5761 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Fixed a minor bug in the login when the channel key is
5764 re-generated in the server. It used to generate the key in
5765 wrong order and thus caused problems in the channel traffic.
5767 * Fixed a minor bug in channel key distsribution after
5768 KICK command. The key was not sent to the router even though
5771 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Added silc_ske_process_key_material_data as generic routine
5774 to process any key material as the SILC protocol dictates. The
5775 function is used by the actual SKE library but can be used by
5776 applications as well. This relates to the private message keys
5777 and the channel private keys since they must be processed the
5778 same way the normal SILC session keys. The protocol dictates
5779 this. Affected files: lib/silcske/silcske.[ch].
5781 Added also silc_ske_free_key_material to free the
5782 SilcSKEKeyMaterial structure.
5784 * Defined silc_cipher_set_key function to set the key for
5785 cipher without using the object's method function. The affected
5786 files: lib/silccrypt/silccipher.[ch].
5788 * Implemented silc silc_client_add_private_message_key,
5789 silc_client_add_private_message_key_ske,
5790 silc_client_del_private_message_key,
5791 silc_client_list_private_message_keys and
5792 silc_client_free_private_message_keys functions in the
5795 Added functions silc_client_send_private_message_key to send
5796 the Private Message Key payload and silc_client_private_message_key
5797 to handle incoming Private Message Key payload.
5799 * Added Cipher field to the Private Message Key payload to set
5800 the cipher to be used. If ignored, the default cipher defined
5801 in the SILC protocol (aes-256-cbc) is used.
5803 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Removed lib/silcclient/ops.h file.
5807 Redefined parts of the SILC Client Library API. Created new
5808 file silcapi.h that deprecates the ops.h file and defines the
5809 published Client Library API. Defined also private message key
5810 API and channel private key API into the file.
5812 This is the file that the application must include from the
5813 SILC Client Library. Other files need not be included by
5814 the application anymore.
5816 * Added new key_agreement client operation callback and also
5817 defined the Key Agreement library API for the application.
5819 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5822 is used by clients to request key negotiation between another
5823 client in the SILC network. If the negotiation is started it
5824 is performed using the SKE protocol. The result of the
5825 negotiation, the secret key material, can be used for example
5826 as private message key.
5828 Implemented the Key Agreement payload into the files
5829 lib/silccore/silauth.[ch].
5831 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Redefined ciphers for the SILC protocol. Added some new ciphers
5834 and defined the key lengths for the algorithms. Changed the
5835 code accordingly. The default key length is now 256 bits.
5837 * Fixed SKE key distribution function silc_ske_process_key_material
5838 when the key length is more than 128 bits. The default key
5839 length in SILC is now 256 bits.
5841 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5842 to indicate unsupported algorithm.
5844 * Renamed rijndael.c to aes.c and all functions as well.
5846 * Fixed a long standing channel key setting bug in client library.
5847 Weird that it has never surfaced before.
5849 * Fixed bug in channel deletion. If the entire channel is removed
5850 then it must also delete the references of the channel entry
5851 from the client's channel list as the client's channel entry and
5852 the channel's client entry share same memory.
5854 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Implemented CONNECT and SHUTDOWN commands in the client.
5858 * Implemented CLOSE command to the client.
5860 * Added the function silc_idlist_find_server_by_name into the
5861 files silcd/idlist.[ch].
5863 Added the function silc_idlist_find_server_by_conn into the
5864 files silcd/idlist.[ch].
5866 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * DIE command was renamed to SHUTDOWN. Updated the both code
5871 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5872 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5874 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5877 * Added function silc_server_create_connection function to create
5878 connection to remote router. My server implementation actually
5879 does not allow router to connect to normal server (it expects
5880 that normal server always initiates the connection to the router)
5881 so the CONNECT command is only good for connecting to another
5884 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5887 or some other client was kicked from the channel.
5889 Implemented the handling of the notify type to both client
5892 Implemented silc_server_send_notify_kicked to send the KICKED
5893 notify. It is used to send it to the server's primary router.
5895 * Implemented the KICK command into server and client.
5897 * Added `query' argument to the silc_idlist_get_client function
5898 to indicate whether to query the client from server or not if
5901 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5902 to indicate that the client is not channel founder.
5906 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Removed the rng context from SilcPacketContext structure and
5909 changed that the packet routine uses the Global RNG API.
5911 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Added support for quit message that client can "leave" on the
5914 channel when it quits the SILC. It is ditributed inside the
5915 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5917 Added silc_server_free_client_data that will take the
5918 signoff message as argument.
5920 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5922 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Updated parts of the protocol specification to keep it up
5927 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5930 payloads in one packet.
5932 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5933 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5934 use now the new List flag.
5936 * Also deprecated the following packet types: REPLACE_ID,
5937 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5939 * Added list support for Notify packet in server.
5941 * Added silc_server_send_notify_channel_change to send the
5942 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5943 the silc_server_send_replace_id.
5945 * Added silc_server_send_notify_nick_change to send the
5946 NICK_CHANGE notify type. Deprecates the function
5947 silc_server_send_replace_id.
5949 * Added silc_server_send_notify_join to send the JOIN notify type.
5950 Deprecates the function silc_server_send_new_channel_user.
5952 * Added silc_server_send_notify_leave to send LEAVE notify type.
5953 Deprecates the function silc_server_send_remove_channel_user.
5955 * Added silc_server_send_notify_cmode and
5956 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5957 types. Deprecates the silc_server_send_set_mode function.
5959 * Added SERVER_SIGNOFF notify type to indicate that server has
5960 quit. This means that all clients on the channel from that
5961 server will drop. This can be also used when netsplit happens.
5963 Deprecated REMOVE_ID packet type since it is not needed anymore
5966 Added silc_server_send_notify_server_signoff to send the
5967 SERVER_SIGNOFF notify type. Deprecates the function
5968 silc_server_send_remove_id.
5970 Added also silc_server_send_notify_signoff to send the
5971 SIGNOFF notify type.
5973 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5974 SILC protocol from this day on. Changed the protocol
5975 specification as well.
5977 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5978 notify type. It is used between routers to notify about
5979 topic changes on a channel.
5981 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5984 * Partly updated the protocol specification to comply with the
5985 changes now made. It is still though a bit outdated.
5987 * The JOIN notify type now takes one extra argument <Channel ID>.
5988 The packet used to be destined to the channel but now the
5989 JOIN type may be sent as list thus it is impossible to
5990 destine it to any specific channel. By adding this argument
5991 it is again possible.
5993 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Added CREDITS file. The CHANGES and CREDITS file will appear
5996 in the distribution as well.
5998 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6001 types in the server's silcd/packet_receive.c.
6003 * Implemented CMODE and CUMODE to work in router environment.
6005 * Fixed minor encoding and decoding buglet from the
6006 lib/silccore/silcmode.c.
6008 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6011 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6013 * Changed all SilcConfigServer* and silc_config_server* to
6014 SilcServerConfig* and silc_server_config*, respectively.
6017 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Associated the ID (client or server ID) to the Authentication
6020 Payload to avoid any possibility of forging. Updated the
6021 protocol specification and the code accordingly.
6023 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * The RSA key length is now save to the RsaKey context in the
6026 key generation process in lib/silccrypt/rsa.c. The key length
6027 is now used to figure out the maximum size of the block allowed
6028 to be encrypted/signed.
6030 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6031 is equivalent to the silc_mp_mp2bin but does not allocate any
6034 * Changed silc_mp_mp2bin API to take length argument. If it is
6035 non-zero then the buffer is allocated that large. If zero, then
6036 the size is approximated using silc_mp_sizeinbase, which however
6039 * Created Global RNG API which is global RNG that application can
6040 initialize. After initializing, any routine anywhere in the
6041 code (including library) can use RNG without allocating a new
6042 RNG object. This was done to allow this sort of use of the
6043 RNG in code that has no chance to allocate RNG object. All
6044 applications currently allocate this and many routines in the
6045 library use this. Affected file lib/silccrypt/silcrng.[ch].
6047 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6048 it to use the Global RNG API.
6050 * Defined Authentication Payload into protocol specification that
6051 is used during SILC session to authenticate entities. It is
6052 used for example by client to authenticate itself to the server
6053 to obtain server operator privileges.
6055 Implemented this payload into the lib/silccore/silcauth.[ch].
6056 Implemented also routines for public key based authentication
6057 as the new protocol specification dictates.
6059 Moved definitions of different authentication methods from
6060 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6062 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6063 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6064 silc_pkcs_verify_with_hash functions into the file
6065 lib/silccrypt/silcpkcs.[ch].
6067 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * The client entry's userinfo pointer must be always valid.
6070 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6071 will fail since it requires the userinfo. Now, the userinfo
6072 is allocated as "" if actual userinfo does not exist. Actually,
6073 it must exist and it is totally Ok to drop client connections
6074 that does not announce the userinfo. However, we will make
6075 this workaround for now.
6077 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6078 to return the remote port by socket.
6080 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6083 SILC_SERVER_PENDING_EXEC and added an new macro
6084 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6085 data or when error occurs while processing the pending command.
6087 Added new argument `destructor' into silc_server_command_pending
6088 and to the SilcServerCommandPending object. This destructor is
6089 now called after calling the pending callback or if error occurs
6090 immediately. If error occurs the actual pending callback won't
6091 be called at all - only the destructor. The destructor may be
6092 NULL if destructor is not needed.
6094 All this applies for client library code as well. Similar
6095 changes were made there as well for the pending commands.
6097 In the client, the application must now allocate the
6098 SilcClientCommandContext with the silc_client_command_alloc
6101 * Added reference counter to the SilcServerCommandContext. Added
6102 function silc_server_command_alloc and silc_server_command_dup
6105 Same type of functions added to the client library for the same
6108 * Removed the cmd_ident from IDListData away since it is now
6109 global for all connections. It is the command identifier used
6110 in command sending and with pending commands. The affected file
6113 * Added reference counter to the SilcSocketConnection objecet to
6114 indicate the usage count of the object. The object won't be
6115 freed untill the reference counter hits zero. Currently only
6116 server uses this, and client ignores it. The client must be
6117 set to use this too later. The affected files are
6118 lib/silccore/silcsockconn.[ch]. Added also the function
6119 silc_socket_dup to increase the reference counter.
6121 This was mainly added because it is possible that the socket
6122 is removed underneath of pending command or other async
6123 operation. Now it won't be free'd and proper DISCONNECTING
6124 flags, etc. can be set to avoid sending data to connection that
6125 is not valid anymore.
6127 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6128 the connection. After that it sets SILC_SET_DISCONNECTED.
6129 It is, however, possible that the socket data is not still freed.
6130 The silc_server_packet_process now checks that data is not
6131 read or written to connection that is DISCONNECTED. The socket
6132 get's freed when the reference counter hits zero.
6134 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Changed the client operation API: channel_message operation's
6137 `sender' is now the client entry of the sender, not the nickname
6138 and the `channel' is the channel entry, not the channel name.
6140 In the private_message operation the `sender' is now also the
6141 client entry of the sender not the nickname.
6143 Affected file is lib/silcclient/ops.h and all applications
6144 using the client operations.
6146 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Moved the calling of ops->connect() from connect_to_server_final
6149 into receive_new_id functin since that is the point when the
6150 client is actually allowed to send traffic to network. The
6151 affected file is lib/silcclient/client.c.
6153 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6156 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6157 (if needs broadcasting) instead of broadcasting the packets one
6158 by one which would make a burst in the network traffic.
6160 * Added `broadcast' argument to the functions in silcd/server.[ch]
6161 silc_server_create_new_channel[_with_id] to indicate whether
6162 to send New Channel packet to primary router.
6164 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Added new function into the silcd/server.[ch] files:
6167 silc_server_create_new_channel_with_id to create new channel with
6168 already existing Channel ID.
6170 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6171 lib/silccore/silcpacket.h. This packet is used t send list of
6172 Set Mode payloads inside one packet. Server uses this to set
6173 the modes for the channels and clients on those channels, that it
6174 announced to the router when it connected to it. The protocol
6175 specification has been updated accordingly.
6177 * The silc_server_new_channel did not handle the packet coming
6178 from normal server as it normally does not send that. However,
6179 when it announces its channels it does send it. Implemented
6180 the support for that.
6182 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6183 into the file lib/silccore/id.h.
6185 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Fixed memory leaks in the functions silc_idlist_del_client,
6188 silc_idlist_del_channel and silc_idlist_del_server in the file
6189 silcd/idlist.c. All of those leaked like a sieve.
6191 * Fixed some small memory leaks in the client's function
6192 silc_client_notify_by_server.
6194 * Added functions into silcd/server.c: silc_server_announce_clients,
6195 silc_server_announce_channels and silc_server_announce_server.
6196 These functions are used by normal and router server to announce
6197 to its primary router about clients, channels and servers (when
6198 router) that we own. This is done after we've connected to the
6201 These functions effectively implements the following packet types:
6202 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6203 and SILC_PACKET_NEW_ID_LIST.
6205 * Added new functions into the silcd/packet_receive.[ch]:
6206 silc_server_new_id_list, silc_server_new_channel_list and
6207 silc_server_new_channel_user_list to handle the incoming
6208 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6210 * Added support of changing Channel ID in the function
6211 silc_server_replace_id. If the server that announces a channel
6212 to the router already exists in the router (with same name but
6213 with different Channel ID), router is responsible to send
6214 Replace ID packet to the server and force the server to change
6215 the Channel ID to the one router has.
6217 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6218 client that the Channel ID has been changed by the router. The
6219 normal server sends this to the client. Client must start using
6220 the new Channel ID as the channel's ID.
6222 Implemented handling of this new type into lib/silcclient/client.c
6223 into the function silc_client_notify_by_server.
6225 * Added new function silc_idlist_replace_channel_id into the files
6226 silcd/idlist.[ch] to replace the Channel ID.
6228 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Call silc_server_command_identify_check always when processing
6231 the IDENTIFY command in silcd/command.c
6233 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6236 send keepalive packets. The packet can be sent by clients,
6237 servers and routers.
6239 Added function silc_socket_set_heartbeat into the file
6240 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6241 If not set, the heartbeat is not performed. The actual
6242 heartbeat is implemented in the low level socket connection
6243 library. However, application is responsible of actually
6246 Added silc_server_send_heartbeat to send the actual heartbeat
6247 packet into silcd/packet_send.[ch]. Server now performs
6248 keepalive with all connections.
6250 * Added silc_task_get_first function into lib/silcutil/silctask.c
6251 to return the timeout task with shortest timeout. There was a bug
6252 in task unregistration that caused problems. TODO has been
6253 updated to include that task system must be rewritten.
6255 * The client library will now resolve the client information when
6256 receiving JOIN notify from server for client that we know but
6257 have incomplete information.
6259 * Rewrote parts of silc_server_remove_from_channels and
6260 silc_server_remove_from_one_channel as they did not remove the
6261 channel in some circumstances even though they should've.
6263 * Encryption problem encountered in server:
6265 The LEAVE command used to send the Channel Key packet to the
6266 router immediately after generating it. However, the code
6267 had earlier sent Remove Channel user packet but not immediately,
6268 ie. it was put to queue. The order of packets in the router
6269 was that Channel Key packet was first and Remove Channel User
6270 packet was second, even though they were encrypted in the
6271 reverse order. For this reason, MAC check failed. Now, this
6272 is fixed by not sending the Channel Key packet immediately but
6273 putting it to queue. However, this is more fundamental problem:
6274 packets that are in queue should actually not be encrypted
6275 because packets that are sent immediately gets encrypted
6276 actually with wrong IV (and thus MAC check fails). So, packets
6277 that are in queue should be encrypted when they are sent to
6278 the wire and not when they put to the queue.
6280 However, the problem is that the current system has not been
6281 designed to work that way. Instead, the packet is encrypted
6282 as soon as possible and left to the queue. The queue is then
6283 just purged into wire. There won't be any fixes for this
6284 any time soon. So, the current semantic for packet sending
6287 o If you send packet to remote host and do not force the send
6288 (the packet will be in queue) then all subsequent packets to the
6289 same remote host must also be put to the queue. Only after the
6290 queue has been purged is it safe again to force the packet
6293 o If you send all packets immediately then it safe to send
6294 any of subsequent packets through the queue, however, after
6295 the first packet is put to queue then any subsequent packets
6296 must also be put to the queue.
6298 Follow these rules and everything works fine.
6300 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Added new function silc_server_remove_clients_by_server to
6303 remove all client entries from ID list when the server connection
6304 is lost. In this case it is also important to invalidate all
6305 client entires as they hold the invalid server entry. This
6306 fixes fatal bug when server has lost connection and will reconnect
6309 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Made some sanity checks to silc_server_daemonise like to check
6312 whether the requested user and group actually exists.
6314 * Added sanity check to SKE's silc_ske_responder_finish to check
6315 that the public and private key actually is valid.
6317 * Invalidate the client's nickname when receiving Replace ID
6318 packet and the Client ID is being replaced. This means that the
6319 server will query the nickname if someone needs it (client)
6322 * Sort the ID Cache in client library when the ID Cache data
6323 has changed (needs sorting).
6325 * Do not allow for SILC client to create several connections to
6326 several servers. The client does not support windows right now
6327 and generating multiple connections causes weird behaviour.
6329 Irssi-silc client does support windows and can handle several
6330 connections without problems, see: www.irssi.org and SILC plugin.
6332 * Fixed some places where client was added to the IDList. The
6333 rule of thumb is following (in order to get everything right):
6334 If the client is directly connected local client then the
6335 `connection' argument must be set and `router' argument must be
6336 NULL to silc_idlist_add_client function. If the client is not
6337 directly connected client then the `router' argument must
6338 bet set and the `connection' argument must be NULL to the
6339 silc_idlist_add_client function.
6341 * The funtion silc_server_packet_send_local_channel actually did
6342 not check whether the client was locally connected or not. It
6343 does that now. Fixed a bug related to LEAVE command.
6345 * Fixed Remove Channel User payload parsing bug in server's
6346 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6348 * The server's silc_server_save_channel_key now checks also the
6349 global ID list for the channel as it might not be in the local
6350 list. Fixed a bug related to LEAVE command.
6352 * Is this the end of the [<unknown>] buglet that has been lurking
6353 around for a long time? A little for loop fix in server's
6354 silc_server_command_whois_parse that is used by both IDENTIFY
6355 and WHOIS command. At least, this was a clear bug and a cause
6356 of one type of [<unknown>] buglet.
6358 * WHOIS and IDENTIFY commands call the function
6359 silc_server_command_[whois/identify]_check function even if
6360 we are not router server.
6362 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Added --with-gmp configuration option. If set the GMP
6365 is always compiled in the SILC source tree. If not set then
6366 it is checked whether the system has the GMP3 installed. If
6367 it has then the GMP won't be compiled (the system's headers
6368 and library is used), if it doesn't have it then the GMP is
6369 compiled in the SILC source tree.
6371 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6373 * Changed RSA private exponent generation to what PKCS #1
6374 suggests. We try to find the smallest possible d by doing
6375 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6376 not security fix but optimization.
6378 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Added new config entry [Identity] to fork the server and run
6381 it as specific user and group. A patch from Bostik.
6383 * Imported Dotconf configuration library into lib/dotconf.
6384 This will be used to create the SILC configuration files later.
6385 It will appear in the distsribution after this commit.
6387 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * A big code auditing weekend happening. Auditing code for
6390 obvious mistakes, bugs and errors. Also, removing any code
6393 Removed files for being obsolete:
6395 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6396 inline in the file lib/silcutil/silcbuffer.h)
6398 o lib/silcutil/silcbufutil.c (the header has inline versions)
6400 Changed code to fix possible error conditions:
6402 o The buffer formatting routines now check that the destination
6403 buffer really has enough space to add the data. This applies for
6404 both buffer formatting and unformatting
6405 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6406 unformatting was changed to accomodate following rules:
6407 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6408 sent to the function while XXX_*STRING will not allocate or copy
6409 the data into the buffer. Instead it sets the pointer from the
6410 buffer into the pointer sent as argument (XXX_*STRING used to
6411 require that the pointer must be allocated already). This change
6412 makes this whole thing a bit more consistent and more optimized
6413 (note that the data returned in the unformatting with XXX_*STRING
6414 must not be freed now). The routines return now -1 on error.
6416 o Tried to find all code that use buffer_format and buffer_unformat
6417 and added return value checking to prevent formatting and
6418 especially unformatting errors and possible subsequent fatal
6421 o Changed ske->x and ske->KEY to mallocated pointers in
6422 lib/silcske/silcske.h. Fixed possible data and memory leak.
6424 o Added return value checking to all *_parse* functions. Fixed
6425 many memory leaks as well.
6427 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6428 so that buffer overflows would not happen. All code now also
6429 checks the return value as it can fail.
6431 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6433 * Added reconnection support to server if the normal server looses
6434 its connection to the router (for example if router is rebooted).
6435 The server performs normal reconnection strategy implemented
6436 to the server. Affected file silcd/server.c.
6438 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Added new packet type SILC_PACKET_SET_MODE that is used to
6441 distribute the information about changed modes (for clients,
6442 channels and clients channel modes) to all routers in the
6443 network. Updated the protocol specification accordingly.
6445 Added functions into silcd/packet_send.c and
6446 silcd/packet_receive.c: silc_server_send_set_mode,
6447 silc_server_set_mode.
6449 Added new files silcmode.[ch] into lib/silccore that implements
6450 the encoding and decoding of Set Mode Payload. Added new type
6451 SilcSetModePayload. Moved the definitions of different modes
6452 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6454 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Oops, a little mistake in server's connection authentication
6457 protocol. The protocol is not ended with FAILURE but with
6458 SUCCESS if the authentication is Ok. :) Affected file is
6461 * Implemented NICK_CHANGE notify handling in server in the file
6462 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6463 the local clients on the channel. After the changing nickname
6464 in router environment snhould work and the [<unknown>] nickname
6465 should appear no more.
6467 The silc_server_replace_id function that receives the Replace ID
6468 payload now sends the NICK_CHANGE notify type also in the file
6469 silcd/packet_receive.c
6471 * Changed WHOIS and IDENTIFY command to support the maximum amount
6472 of arguments defined in protocol specs (3328 arguments). This
6473 fixed a bug that caused problems when there were more than three
6476 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Added extra parameter, command identifier, to the
6479 silc_client_send_command so that explicit command identifier
6482 Changed that ID list routines uses specific command identifier
6483 when sending WHOIS/IDENTIFY requests to the server so that they
6484 can be identified when the reply comes back.
6486 Affected files lib/silcclient/command.[ch],
6487 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6489 * Added `sender' argument to silc_server_packet_send_to_channel
6490 to indicaet the sender who originally sent the packet to us
6491 that we are now re-sending. Ignored if NULL. Affected file
6492 silcd/packet_send.[ch].
6494 * Added some server statistics support in silcd/server_internal.h
6495 SilcServerStatistics structure and around the server code. Also
6496 send some nice statistics information when client is connecting
6499 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Fixed channel ID decoding in server's JOIN command reply in
6502 silcd/command_reply.c
6504 * Fixed braodcasting of replace ID payload to not to send it if
6505 we are standalone server in silcd/packet_receive.c.
6507 * Fixed all channel message sending routines to not to send
6508 packets to clients that has router set, since they are routed
6509 separately in the same function earlier. Affects file
6510 silcd/packet_send.c and all channel packet sending functions.
6512 * In USERS reply, res_argv[i] are not allocated, the table
6513 is allocated. Thus changed that free the table, not its
6516 * In server's whois_check and identify_check if the client is
6517 locally connected do not send any WHOIS commands - they are not
6520 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Fixed some minor bugs in client when sending WHOIS command. The
6523 arguments was in wrong order.
6525 * Removed statis function add_to_channel from server in
6526 silcd/command.c that was previously used with the joining but
6529 * Tested USERS command in router environment successfully with two
6530 routers, two servers and two clients.
6532 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Reorganized the USERS command and command reply in client library
6535 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6536 When the command is given by user we register a pending command
6537 callback that will reprocess the command after the reply has been
6538 received from the server. When reprocessing the packet we then
6539 display the information. Thus, the USERS information is displayed
6540 now in the command callback instead of in the command reply
6541 callback. The processing of the command is same as previously
6542 when server has sent the command reply in the JOINing process.
6544 * Added to USERS command in silcd/command_reply.c to join the client,
6545 we didn't use to know about, to the channel after we've created
6546 a client entry for it. Also, for clienet we did know already still
6547 check whether it is on the channel or not and add it if not.
6549 * Removed silc_server_command_join_notify as the function and its
6552 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Changed the client's pending command handling to the same as the
6555 server's pending command handling. It is also now possible to
6556 execute command reply functions from other command reply
6557 function as the function callbacks for commands and command
6558 replies are one and same. The pending commands are not static
6559 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6560 in client connection context. Thus, pending commands are server
6561 connection specific as it is convenient.
6563 Changed the function silc_client_command_pending and
6564 silc_client_command_pending_del and added new function
6565 silc_client_command_pending_check. Removed the
6566 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6569 * Added cmd_ident, current command identifier, to the client
6570 connection context in lib/silcclient/client.h to keep track on
6571 command identifiers used in command sending. Client's command reply
6572 function handling now supports the mandatory command identifiers.
6574 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6575 funtions in client to fully support pending command callbacks.
6577 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6578 as one of the arguments to the application in the command reply
6581 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6582 before first releasing SILC but came back. Now it is removed again
6583 and should come back nomore. The FORWARDED flag was used only
6584 by the JOINing procedure by forwarding the command packet to router.
6585 Now, the JOINing procedure has been changed to more generic (due
6586 to various router environment issues) and FORWARDED is not needed
6587 anymore for anything. The protocol specification is yet to be
6590 Now, removed silc_server_packet_forward from server and the flag
6591 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6593 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Renamed NAMES command to USERS command. The NAMES was named that
6596 due to historical reasons. Now it is renamed. Also, rewrote
6597 parts of the USERS command. The nickname list is not sent anymore
6598 by the server. Only Client ID and mode lists are sent in the USERS
6599 command. Changed this also to the protocol specification.
6601 The client now resolves the names and stuff after it receives
6602 the USERS list from the server when joining to the channel.
6604 * WHOIS and IDENTIFY commands has been changed to support multiple
6605 Client ID's per command. One can now search for multiple users
6606 in the network by sending only one WHOIS or IDENTIFY command.
6607 Changed the code and the protocol specifications.
6609 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6610 uses silc_server_command_whois_parse to parse the request. */
6612 * If normal server, do not parse the WHOIS and IDENTIFY requests
6613 before sending it to the router. Saves some time.
6615 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Fixed JOIN command on client library. Wrong number of arguments
6618 used to crash the client.
6620 * Added silc_server_channel_has_global function to check whether
6621 channel has global users or not.
6623 * Added silc_server_channel_has_local function to check whether channel
6624 has locally connected clients on the channel.
6626 * The silc_server_remove_from_one_channel now checks whether the
6627 channel has global users or not after given client was removed from
6628 the channel. It also checks whether the channel has local clients
6629 on the channel anymore. If it does not have then the channel entry
6630 is removed as it is not needed anymore.
6632 * The silc_server_notify now checks on JOIN notify whether the joining
6633 client is one of locally connected or global. If it is global then
6634 the channel has now global users on the channel and that is marked
6635 to the channel entry. Also, it now saves the global client to
6636 global list who is joining and JOINs it to the channel. This is
6637 for normal server, that is.
6639 Changed silc_server_send_notify_on_channel,
6640 silc_server_packet_relay_to_channel and
6641 silc_server_packet_send_to_channel check if we are normal server
6642 and client has router set (ie. global client) do not send the
6643 message to that client, as it is already routed to our router.
6645 * Implemented LEAVE notify type handling in silc_server_notify
6648 * Tested LEAVE command in router environment successfully. Tested
6649 with two routers, two servers and two clients.
6653 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6655 * Implemented SIGNOFF notify type handling in silc_server_notify
6658 * silc_server_remove_id now removes the client entry from all channels
6659 it has joined and thusly sends SIGNOFF notify type.
6661 * Rewrote the NAMES list generation in server by removing two excess
6662 loops. The lists are created now inside one loop.
6664 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * silc_server_remove_channel_user checks now also global list
6667 for channel and client.
6669 * silc_server_new_channel_user checks now both local and global
6670 list for channel and client. Fixed a bug in client id decoding.
6671 Used to decode wrong buffer.
6673 * silc_server_channel_message checks now both local and global
6674 list for channel entry.
6676 * Tested channel joining (hence JOIN) in router environment
6677 successfully. Tested with two routers, two servers and two
6680 * Tested channel message sending in router environment successfully.
6682 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Added silc_server_save_channel_key into server.[ch] to save the
6685 received channel key in Channel Key payload processing. It is
6686 also used in JOIN command reply handling.
6688 Equivalent function silc_client_save_channel_key added into
6689 client.[ch] into client library.
6691 * Changed JOIN command reply to send information whether the channel
6692 was created or not (is existing already) and the channel key
6693 payload. Changed protocol specs accordingly.
6695 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6696 the request was sent by ID and not by nickname. Crashed on
6699 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6702 now correctly save the received data.
6704 * silc_server_free_sock_user_data now notifies routers in the
6705 network about entities leaving the network.
6707 At the same time implemented functions silc_server_remove_id
6708 and silc_server_send_remove_id to receive and send REMOVE_ID
6709 packets. The packet is used to notify routers in the network
6710 about leaving entities. The ID removed will become invalid in
6713 * Added function silc_idlist_del_server into server. Removes and
6714 free's server entry from ID list.
6716 * silc_server_private_message function now checks, if we are router,
6717 that the destination ID really is valid ID, naturally.
6719 * In router when NEW_ID packet is received (for new client) the
6720 hash of the Client ID is saved in the ID Cache but the
6721 client->nickname is set to NULL, instead of putting the hash
6724 IDENTIFY command now also checks that client->nickname must be
6725 valid. If it is not if will request the data from the server who
6726 owns the client. Added new function
6727 silc_server_command_identify_check.
6729 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6730 to set the command to already allocated Command Payload.
6732 * Tested private message sending in router environment with two
6733 routers, two servers and two clients. Fixed minor bugs and now
6736 * Fixed segfault from client's NAMES command. Used to crash if
6739 * Forwarded packets must not be routed even if it is not destined
6740 to the receiver. Changed server code comply with this.
6742 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Added `require_reverse_mapping' boolean value to ServerParams
6745 structure. If TRUE (not default) the server will require that
6746 the connecting host has fully qualified domain name.
6748 If the reverse mapping is not required and hostname could not be
6749 found the IP address is used as hostname.
6751 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Implemented version string checking to both client and server.
6754 The check is incomplete currently due to the abnormal version
6755 strings used in development version of SILC.
6757 * Changed all command functions in server to use the new
6760 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * Changed char *data to unsigned char *data in ID Cache system to
6763 support binary data as ID Cache data. Changed code to support
6764 binary data in lib/silccore/idcache.c.
6766 * Renamed silc_server_packet_relay_command_reply to
6767 silc_server_command_reply as it is normal packet receiving
6768 function. Rewrote the function to accept command replys for
6769 servers and not only for clients.
6771 * Mark remote router always as registered server if we are connecting
6772 to it. Otherwise, commands sent by the router to us are ignored.
6774 * All ID List find routines now returns the ID Cache Entry pointer
6775 as well if requested.
6777 * WHOIS command works now in router environment, tested with two
6778 routers, two servers and two clients.
6780 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6781 in router environment (as it is almost equivalent to WHOIS) but
6782 hasn't been tested thoroughly. Added new functions:
6784 silc_server_command_identify_parse
6785 silc_server_command_identify_send_reply
6786 silc_server_command_identify_from_client
6787 silc_server_command_identify_from_server
6789 * Disabled route cache adding because adding two different ID's with
6790 same IP replaces the old cache entry thus giving wrong route.
6791 The entry->router->connection is always the fastest route anyway
6792 so route cache may not be needed. Of course, new routes maybe
6793 established after receiving the ID when the entry->router->connection
6794 might not be anymore the most optimal.
6796 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Add route cache for received ID for fast routing.
6800 * Added silc_server_packet_route to route received packet on router
6801 that is not destined to us.
6803 * Renamed silc_server_get_route to silc_server_route_get.
6805 * Added id_string and id_string_len fields into SilcServer to
6806 include encoded ServerID for fast comparing without excess
6807 encoding of the ID's.
6809 * Cleaned up WHOIS command on server side. Added following static
6812 silc_server_command_whois_parse
6813 silc_server_command_whois_check
6814 silc_server_command_whois_send_reply
6815 silc_server_command_whois_from_client
6816 silc_server_command_whois_from_server
6818 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6819 arguments in command replies. All command functions should be
6820 updated to use this macro.
6822 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * Minor typo fixes on command reply handling on server.
6826 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added silc_server_command_add_to_channel internal routine to add
6829 the client to the channel after router has created the channel and
6830 sent command reply to the server.
6832 * Added generic silc_server_send_command to send any command from
6835 * Use static buffer with ID rendering instead of duplicating data.
6837 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Fixed a channel user mode bug when joining to a channel server gave
6840 everybody channel founder rights, oops.
6842 * We mark ourselves as the router of the incoming server connection
6843 if we are router ourselves. This way we can check in some packet
6844 sending functions whether it is locally connected server. For
6845 incoming router connections we put NULL.
6847 * For router sending packets locally means now always sending the
6848 packet cell wide; to local clients and local servers. For normal
6849 server sending packet locally means sending it to only local
6852 * Fixed the JOIN command to really work in router environment. If the
6853 channel is created it is always created by the router. Router is
6854 also responsible of making the initial joining to the channel,
6855 sending JOIN notify to the sending server and distributing
6856 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6857 does not exist server doesn't do anything else but forward the
6858 command to the router which performs everything.
6860 * Added silc_server_send_channel_key function to send the Channel Key
6863 * Added silc_server_create_channel_key to create new channel key. The
6864 channel key is now re-generated everytime someone joins or leaves
6865 a channel, as protocol dictates. Note: channel->key_len is the
6868 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6871 packet_receive.[ch] to separate packet sending and receiving
6872 routines. The server.[ch] now includes everything else including
6873 actual packet processing (writing and reading data) and other
6876 Renamed silc_server_private_message_send_internal to
6877 silc_server_send_private_message. The routine is still though
6878 used only to relay private messages as server does not send
6879 private messages itself.
6881 Renamed silc_server_new_channel to silc_server_create_new_channel
6882 and added new function sicl_server_new_channel that handles the
6883 incoming New Channel packet. Added also new sending function
6884 silc_server_send_new_channel to send New Channel Payload.
6886 * Added new function silc_server_notify to process incoming notify
6887 packet to the server/router. Server may then relay the notify
6888 to clients if needed.
6890 * Added new function silc_server_new_channel_user to process incoming
6891 New Channel User packet. Router will redistribute the packet and
6892 send JOIN notify to its local clients and locally connected servers
6893 if needed. Normal server will send JOIN notify to its local client
6894 on same channel when received this packet. Added also corresponding
6895 sending function silc_server_send_new_channel_user to sent the
6898 * Added boolean route argument to send_notif_to_channel and
6899 packet_send_to_channel functions to attempt to route the packet
6900 if it is TRUE and send only locally if it is FALSE.
6902 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6904 * silc_server_replace_id now broadcasts the received replace ID
6905 packet if it is not broadcast packet already. The router must
6906 broadcast to inform other routers about changed ID.
6908 * Added backpointer to server's router into SilcServer context in
6909 silcd/server_internal.h.
6911 * Fixed silc_server_packet_broadcast to send correct broadcast
6914 * The channel key is now distributed to the local client as soon
6915 as it is received from the router (in router environment) so that
6916 no other packet may be sent for the channel until client has
6919 * silc_server_remove_channel_user now broadcasts the received
6920 Remove Channel User packet if it is not broadcast packet already.
6921 The router must broadcast to inform other routers about removed
6924 * Added users field into SilcPacketContext that is a reference count
6925 of the context. One can increase the reference count by calling
6926 silc_packet_context_dup which is now changed to just increase the
6927 reference count instead of duplicating the data. The reference
6928 count is decresed by calling silc_packet_context_free that will
6929 free the data after the reference count hits zero.
6931 For now on the packet context and everything allocated into it
6932 (including the raw packet from network) must be freed by calling
6933 the new silc_packet_context_free function. Added also new function
6934 silc_packet_context_alloc that must be used now to allocate the
6935 context. This also means that if a routine is asynchronous from
6936 silc_[client/server]_packet_parse_type the packet context must
6937 be duplicated by calling silc_packet_context_dup. Otherwise it
6938 gets free'd after silc_[client/server]_packet_parse_type returns.
6939 Also, one must remember that if packet is duplicated then its
6940 reference count must be decresed by calling the free function as
6941 many times as it was duplicated.
6943 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6944 from both client and server.
6946 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Made joining to a channel working in router environment.
6950 * Cleaned up JOIN command on server side and create function
6951 silc_server_command_join_channel internal routine to make the
6954 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6956 * Changed silc_command_pending list to SilcDList. Also, added
6957 `ident' field to SilcServerCommandPending structure to identify
6958 the reply and to call correct callback.
6960 Added silc_server_command_pending_check function to replace the
6961 corresnponding macro. The silc_command_pending list is not
6964 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6965 to set identifier to previously allocated Command Payload. It
6966 is used to set identifier for command when resending Command
6969 * Added silc_command_payload_encode_payload to encode Command
6970 Payload buffer from SilcCommandPayload structure.
6972 * Added silc_argument_payload_encode_payload to encode Argument
6973 payload buffer from SilcArgumentPayload structure.
6975 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Changed WHOIS command to support router connection on server side.
6978 The whois request is always sent to router unless the server is
6979 standalone server. After server has received the reply from the
6980 router will it send the reply to the client.
6982 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6983 broadcast received broadcast packet. The function is used only
6984 by router. The broadcast packet is always sent to the router's
6987 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6988 render given ID to printable string, for log files for example.
6990 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Made basic router to router connections working. At least they
6993 can now connect to each other but nothing really works the way
6994 they are supposed - yet.
6996 * Added new initiator token to RouterConnection configuration
6997 file in silcd/serverconfig.[ch]. It is used to tell whether we
6998 are the initiator to the remote router or whether we'll expect
6999 the other end to connect.
7001 * Moved registering of listener task to silc_server_init, hence
7002 the server starts listenning as soon as it is run, even if it
7003 does not have connections to other routers. Let's see how well
7006 * Changed default connection retry timeouts for more suitable in
7009 * Removed cipher and such arguments from silc_idlist_add_client
7010 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7011 Added new function silc_idlist_add_data to add the keys and stuff
7014 * Added SilcIDListData structure and added it to SilcClientEntry
7015 and SilcServerEntry as their first field in the structure. This
7016 way we can explicitly cast the ID entries to the SilcIDListData
7017 structure and get common data for the entries. In past, we had
7018 to first check what type of connection it is and then cast it to
7019 correct ID entry type. Now, we can directly cast the opaque
7020 pointer to the SilcIDListData (no matter what ID entry it actually
7021 is) and get the data needed.
7023 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7025 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7026 in some circumstances even if threre were timeout tasks, though not
7027 IO tasks, but tasks anyway. Now fixed.
7029 * Defined SilcServerConnection structure to hold connection specific
7030 stuff about directly connected servers and routers. The definition
7031 is currently in silcd/server_internal.h. I thought about having
7032 a bit more important role fro this struct but for now it is used
7033 only when connecting to other server (or router actually).
7035 * Added connecting retry support in server when connecting to
7036 router(s). The retry feature implement exponential backoff
7037 algorithm. Also, added SilcServerParams structure to hold default
7038 parameters for server. For now, it include these retry settings
7039 and are hard coded. After server is moded to be as Silc Server
7040 Library this structure will be more important.
7042 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Changed client librarys channel->clients table to SilcList and
7045 changed code accordingly.
7047 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Changed client's channel table to SilcList and changed code
7050 accordingly. Also changed SilcChannelClientEntry to include back-
7051 pointer to the channel so that client entry can use that structure
7052 as list as well and we have fast cross-reference to the channel.
7053 This change dramatically decreased the complexity of channel
7054 handling with client entry and vice versa (removed one extra
7055 loop when searching for channel entry from many functions).
7057 * Changed server->sim from table to SilcDList and changed code
7060 * NAMES command can now be used from user interface. It will show
7061 the user list on the channel, neatly.
7063 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7064 Code now saves realname of the user if it becomes available.
7066 * Renamed configure.in to configure.in.pre and made ./prepare
7067 script to automatically add correct version string to
7068 configure.in which it creates from configure.in.pre.
7070 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * NAMES command reply now shows users mode with the nickname when
7075 * Moved silc_client_ch[u]mode[_char] functions from
7076 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7077 place sucks, they are utility functions and should be in some
7080 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7082 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7085 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Added TRQ (efficient deque and list library) into lib/trq. This is
7090 a very good list library that is currently used in the SILC. Defined
7091 SilcList API over the library because I didn't like the API very
7092 much. See lib/trq/silclist.h for the API and examples of how to
7093 use the API. Fixed various places in the code to use the new
7094 SilcList API. The SilcList is meant for lists that has a structure
7095 already defined as a list. It is not suitable to add just some
7096 context to the list (in TRQ, the context is the list actually).
7098 So, I defined SilcDList that can be used for the purpose where
7099 predefined list structure does not exit. This can be used as
7100 such list. Now some context just can be added to the SilcDList.
7101 Currently this list is not used in the SILC just yet, though there
7102 are a lot places where this can replace dynamically allocated
7103 tables and I will fix these places, later, to use SilcDList.
7104 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7105 and use TRQ internally).
7107 Also fixed some annoying warning messages that the original TRQ
7108 code generated. Also minor changes to TRQ's Makefile.in.
7110 * Added support for querying by Client ID to both WHOIS and
7111 IDENTIFY commands into server, as required by the protocol.
7113 * Removed method function pointers from SilcBuffer structure. They
7114 weren't used to anything and just increased the context size for
7115 no good reason. This change also made silc_buffer_alloc and
7116 silc_buffer_free functions inline functions.
7118 * Disabled command flooding detection support until it's fixed so
7119 that it accepts commands in but does not execute them more than once
7122 * Added silc_net_localhost(), to return local hostname, into
7123 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7124 that must be initialized before calling silc_client_init.
7126 * Added new function: silc_server_send_notify_on_channels to send
7127 notify messages to all channels client has joined. It is assured
7128 that the message is sent only once per client.
7130 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7131 lib/silcutil/silcutil.[ch] as silc_format function. The new
7132 function is generic and is used by server as well, not only by
7133 the logging routines.
7135 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7136 the provided version string was not acceptable. Added new function:
7137 silc_ske_check_version into lib/silcske/silcske.h. The function
7138 must be implemented by the application (client or server) and it
7139 does not reside in the SKE library. The function checks the version
7140 string remote end sent.
7142 * Added back pointers (to opaque context and to SilcSocketConnection)
7143 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7145 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7146 duplicate packet context structure.
7148 * Changed `notify' client operation to send same arguments as client
7149 receives from server except for ID's. ID's are mapped to correct
7150 ID entry and that is returned. Also, if channel entry is not sent
7151 by server but the notify is for channel the channel entry is sent
7152 to application (otherwise application doesn't know that it is for
7153 channel (library gets it from packet's Destination ID)).
7155 * Added silc_client_remove_from_channels into client library to
7156 remove a client from all channels it has joined to. Used when
7157 received SIGNOFF notify from server. Added also new function
7158 silc_client_replace_from_channels to replace old ID entry with
7159 new ID entry on all channels. Used when received NICK_CHANGE
7162 * Fixed ID Cache list handling in silc_idlist_get_client in
7163 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7164 to get (or query) client by ID.
7166 * Updated TODO list.
7168 * Added connection authentication status message defined by the
7169 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7170 support for these into the code in client and server side.
7172 * Added generic function silc_client_send_command to send any command
7173 with variable argument list. Application should use this function
7174 to send commands if the command functions provided by the library
7175 does not suite for the application's user interface needs.
7177 * Added new `failure' client operation. Application is notified about
7178 received failure packet if client is executing a protocol. In this
7179 case the protocol's execution has failed.
7181 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7182 is required by the protocol.
7184 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7185 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7188 * Added status flag to SilcSKE object to indicate realtime status
7189 of the SKE protocol.
7191 * Application receives now exactly same command reply arguments as
7192 the library receives from server. However, if ID is received the
7193 corresponding ID entry is returned to the application (eg. Client
7194 ID is mapped to correct SilcClientEntry entry and that is returned).
7195 Changed command_reply client operation due to this change.
7197 * Changed all ID's in commands and in command replys as ID Payloads.
7198 Change affected both client and server side codes.
7200 All ID's sent in SILC network (with execption of ID's in SILC
7201 Packet header) are sent in ID Payload to support variable length
7204 * Server now notifies nick changes and notifies all clients on
7205 the channels about the new nickname (about the new Client ID,
7208 * Implemented CMODE command to change channel modes. Supports all
7209 channel modes defined by the protocol specs except ban and invite
7210 lists. (Also, private channel key mode is supported but support for
7211 setting private channel key in client is missing, thus, this mode
7212 has no effect on client side (except that server requires that the
7213 client uses private channel key and normal channel traffic does not
7216 Also, invite mode works per se, but INVITE command does not work
7217 yet correctly, so you can set channel as invite only channel but
7218 inviting clients to the channel does not work (it is yet to be
7219 thought what's the best way to do it).
7221 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7222 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7223 Implemented CUMODE command to change user's mode on the channel.
7224 Supports all modes defined by the protocol specs.
7226 * Added NAMES command reply to return users modes on the channel.
7228 * Removed unnecessary and slow ciphers from lib/silccrypt.
7230 * Set SO_KEEPALIVE option to connection sockets by default.
7232 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7234 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7235 redefined the Notify Payload into protocol specs.
7237 * Added silc_id_payload_parse_id to get ID directly from raw
7240 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7243 accept searching by Client ID as well.
7245 * Added support for LEAVE and SIGNOFF notify types in client library.
7247 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7248 to parse ID Payload from raw data.
7250 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7252 * Added flags parameter into silc_ske_assemble_security_properties
7253 function in lib/silcske/silcske.[ch].
7255 * Changed notify client operation to fit better for notify messages
7256 sent by server. The notify payload received from server is now
7257 passed to the application (after parsing it to SilcNotifyPayload).
7258 It is application's responsibility to retrieve the arguments
7259 from the payload and show the message the way it wants. The message
7260 sent by server is implementation specific.
7262 * Changed public keys to comply with the protocol specification.
7263 Old public keys are not supported anymore and are not compatible.
7265 * Removed nickname from Channel Payload as the latest draft removed
7266 it. The client must resolve the nickname from the NAMES command
7267 reply received when it joined the channel.
7269 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7271 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7273 * Fixed some errors in protocol specification drafts.
7275 * Created lib/silccore/silcnotify.c to implement Notify Payload
7276 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7277 generic payloads described by protocol specifications. The file
7278 includes implementations for ID Payload and Argument Payload.
7280 * Changed Command Payload implementation to use the new Argument
7281 Payload. Changed command_xxxx_payload to command_payload_xxxx
7282 to comply with SILC coding conventions.
7284 * Added suppport for Argument Payload handling in Notify Payload
7285 implementation as protocol requires it. Added the new support
7286 into server and client lib as well.
7288 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Added support for multiple nicknames on same channel. [n] is
7291 added locally to the nickname if there are more than one same
7292 nicknames on the channel.
7294 * Server now sends all nicknames that matched WHOIS request.
7295 Client also shows the list received from server.
7297 * Added TOPIC command to client side. User can now set and show
7298 current topic on channel.
7300 * Added MOTD command to client and server. Also, server sends the
7301 motd when client connects to the server.
7303 * Changed version strings to comply ISO 8601.
7305 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7307 * Fixed protocol error handling in client library. It should now
7308 cope even if the SKE fails for some reason.
7310 * Made new protocol specification drafts for submitting to IETF.
7312 * Implemented TOPIC command to server in silcd/command.c.
7314 * Added two new notify types into lib/silccore/silcnotify.h:
7315 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7316 notify nickname change and topic setting/change on a channel.
7318 * API change of command_reply operation in client library. The
7319 application gets now the status type received from server as well.
7321 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7323 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7325 * Cras fixed and optimized the packet handling even further and
7326 it should work now. Minor change to the prototype of function
7327 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7329 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Added new function into lib/silcutil/silcschedule.[ch]:
7332 silc_schedule_with_fd to select() a specified fd. The function
7333 returns after timeout expires or data arrives or goes. The
7334 function is used by packet routines to wait that all data is
7335 received from network.
7337 * Fixed data reading from network in lib/silccore/silcpacket.c.
7338 The code now assures that all data is read from the fd and then
7339 continues packet processing. This was a bug fix since the code
7340 used to drop some data in some circumstances.
7342 * Added new function into lib/silcclient/client.[ch]:
7343 silc_client_start_key_exchange to start key exchange after
7344 connection has been established to server. The code internally
7345 now uses this funtion but its main purpose was to provide it
7346 for applications that perform their own connecting. After
7347 application has created a connection it merely calls this
7348 function to start the key exchange between client and server.
7349 The library takes care of everything else after that.
7351 Updated also lib/silcclient/README to explain the usage of
7354 * Do not send to application information that connection has
7355 been established. Application gets notified it by connect
7358 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7360 * Applied cras's patch to add silc_schedule_one function. The
7361 function runs scheduler once and returns.
7363 * Fixed the scheduler after cras messed it up. The timeout
7364 handling works now as it's supposed to work.
7366 * Added into lib/silccore/ silcnotify.h to include notify
7367 message types support. Changed silc_server_send_notify*
7368 functions, in server.[ch], to support those new notify types.
7369 Added the support for the notify types into client library,
7370 as well. Added new notify client operation into ops.h in
7373 * Changed silc_server_packet_send_to_channel to send normal
7374 packets instead of just channel message packets. The function
7375 is now used to send the notify packets to channels. It is not
7376 used to send channel message packets anymore, as server never
7379 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7380 va_arg()s as it seems to require it nowadays. I guess, if SILC
7381 is compiled with older va_arg() the new code should work anyway.
7383 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7385 * Splitted core library. Core library (lib/silccore) includes
7386 now only SILC protocol specific core (and common) components.
7387 Created new utility library (lib/silcutil) that includes more
7388 generic purpose stuff. The stuff for util library was taken
7389 from the old core library. This was minor and easy split.
7391 * Created SILC Client Library (lib/silcclient) that includes
7392 implementation of the SILC client without user interface. This
7393 was major move from silc/ directory. The code has been changed
7394 so that it is transparent towards the user interface. The
7395 silc/ directory includes now the same user interface as before
7396 and it uses the new client library. Read lib/silcclient/README.
7397 Basicly, the client library performs everything else related
7398 to SILC except user interface handling. Also, configuration
7399 files are considered to be part of user interface and library
7400 does not handle them.
7402 This change also changed a lot of structures, function naming etc.
7403 Most important change was that SilcClientWindow object was
7404 renamed to SilcClientConnection in the client library. Created
7405 also new file lib/silcclient/ops.h. Also added new files
7406 silc/local_command.[ch] and silc/client_ops.[ch].
7408 All these changes were made to make it easier for user interface
7409 designers to create what ever user interface for the SILC client
7412 It is also expected that the server will be moved to lib
7413 directory as well and SILC Server Library will be created;
7414 sometimes in the future.
7416 * Removed Local commands from lib/silccore/silccommand.h as
7417 they are application specific and new client library does not
7418 handle any of those anymore.
7420 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7421 old client implementation in silc/.
7423 * Added support for callback functions in SILC_LOG_* macros.
7424 Application can now set its own callbacks that will be called
7425 instead of using the default functions that will always print
7426 the debug messages to stderr (or stdout). Also, debugging can
7427 now be disabled by setting silc_debug to FALSE and re-enabled by
7428 setting it to TRUE. Note, that logging will still work even
7429 if debugging is disabled.
7431 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7432 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7433 silc_log_reset_debug_callbacks.
7435 * To enable debugging in silc client one must give now -d
7436 option on command line.
7438 * Changed silc_schedule_init to automatically allocate task queues
7439 if they are not allocated before calling it.
7441 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Added GMP 3.1 into math library.
7445 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7448 a channel in SILC network. The packet is used by servers and
7449 routers to notify other routers that user has left a channel.
7450 This little feature was missing until now. Added the feature
7451 to protocol specification as well.
7453 Added functions: silc_server_send_remove_channel_user and
7454 silc_server_remove_channel_user into server.[ch].
7456 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7457 lib/silccore/silcpacket.h. However, they are not implemented
7460 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7462 * Fixed joining to a channel and sending channel messages
7463 between server and router. The channel message sending should
7464 now work inside a cell.
7466 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Fixed the private message sending between server and router.
7469 The private message sending should now work inside a cell.
7471 * Added silc_server_replace_id into server.[ch] to replace
7472 existing ID in the SILC network.
7474 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7475 and silc_idlist_replace_server_id into idlist.[ch] in server.
7477 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Fixed the server to server connections. Server can again now
7480 connect to router. Router to router connections probably does
7483 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7485 * Added dynamic protocol registering support. Now protocols can
7486 registered and unregistered on the fly. Patch by cras.
7488 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7490 * Added lib/contrib directory to hold routines that some platforms
7491 don't have but are needed by SILC.
7493 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7494 into lin/contrib to provide getopt() and getopt_long() for
7495 those who don't have it.
7497 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Added AWAY command to client. When away message is set and
7500 client receives a private message packet the client automatically
7501 replies to the sender with the away message.
7503 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7504 bug seemed to be the cause of recent problems when compiling
7507 * Added version detection support to SKE protocol specification
7508 and added the new changes to the SKE implementation as well.
7509 There were other minor changes in the SKE protocol as well.
7511 Many changes in lib/silcske/silcske.[ch] and in
7512 lib/silcske/payload.[ch].
7514 * Added ^U functionality, clear input line. Patch from cras.
7516 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7518 * Mainly small bugfixes on core library. Fixed some debugging
7519 logging and buffer overflow in silclog.c.
7521 * Updated config.sub and config.guess on the distribution tree.
7523 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Added command lagging support in server. Client may execute
7526 commands now only once in two seconds.
7528 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7530 * Optimized packet reception. MAC computation and checking is now
7531 also more optimized. A lot previously duplicated code is now
7532 used as generic by both client and server.
7534 * Fixed key pair generation in clientutil.c
7536 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7538 * Added into lib/silccore/silcbufutil.[ch] new function;
7539 silc_buffer_realloc.
7541 * Moved generic packet sending/encryption functions to
7542 lib/silccore/silcpacket.[ch] from client and server. Some
7543 rewriting of the functions.
7545 * Moved all generic packet reception/decryption functions to
7546 lib/silccore/silcpacket.[ch] from client and server. The
7547 packet processing is now much cleaner in both client and server.
7548 These were major changes in both client and server.
7550 * Created many common functions in server to do packet sending.
7551 Previously code were duplicated a lot, this has been removed
7554 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Rewrote major parts of the ID cache system. Don't know
7557 whether it is better now or not but at least the API is more
7560 * Major rewrite on ID cache stuff on client because of the ID
7561 cache API changes. Added idlist.c to client.
7563 * Also major rewrite on ID cache stuff on server as well.
7564 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7565 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7566 in hand, instead they are all put into the ID cache system now.
7567 All server_idlist_* routines uses ID cache now instead of
7568 traversing its own lists (those lists does not exist anymore).
7569 SilcIDList though still exists. Also, SilcXXXEntry's are
7572 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7574 * Finally made the SKE implementation compliant to the protocol
7575 specification. All mp integers are now binary encoded as
7576 opposed being HEX encoded.
7578 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7581 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7582 functions: silc_[encode/decode]_pem. Also added function
7583 silc_encode_pem_file to PEM encode with newlines ('\n') for
7586 * SILC public keys are now encoded either PEM or binary. Same
7587 option is for private keys as well. By default private keys
7588 are binary encoded and public keys PEM encoded. Silly HEX
7589 encoding were removed.
7591 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7592 function to create fingerprints.
7594 * Fixed a bug in SHA1; does not change the original data anymore.
7596 * Partly implemented INFO command on client and server side.
7597 Fixed CLEAR command. Changes to SERVER command; show current
7598 server(s) when giving command without arguments. Added
7599 VERSION command to client.
7601 * Added check to server that unregistered connections cannot
7602 execute commands (unless it is specificly allowed).
7604 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Fixed screen refresh.
7608 * Fixed channel joining bug from client. On some circumstances
7609 client tried to join to a channel it had already joined.
7611 * Added public key verification process into client's protocol.c.
7612 The client now verifies the public key from user and saves
7613 it into ~./silc/serverkeys/ directory.
7615 Added into: clientutil.[ch]: silc_client_verify_server_key.
7617 * Changed SKE protocol's silc_ske_initiator_finish function
7618 to accept callback function that verifies the received public
7619 key. Removed old silc_ske_verify_public_key function.
7621 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7624 silc_pkcs_private_key[_data]_set.
7626 * Made the password and public authentication more cleaner in
7627 server's protocol.c.
7629 * Removed historic and obsolete protocol `channel_auth' from
7630 both client and server.
7632 * Removed wrong way of sending command status messages from
7633 server to client in server's command.c. The old way violated
7634 protocol specification.
7636 Changes to silccore/silccommand.[ch]: removed
7637 silc_command_encode_status_payload -> not needed anymore,
7638 changed silc_command_encode_payload_va to accept extra
7639 argument on variable argument list. The argument type must
7640 now be provided to the function. Also, added new function:
7641 silc_command_encode_reply_payload_va which is same as
7642 normal command_encode_payload_va except command status type
7643 is provided as extra argument.
7645 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7647 * Added ~./silc directory handling. The directory includes the
7648 public and private keys for the client.
7650 Added silc_client_check_silc_dir, silc_client_create_identifier
7651 and silc_client_load_keys.
7653 * Implemented SILC protocol compliant public key. Added public
7654 and private key saving to and loading from files.
7656 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7657 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7658 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7659 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7660 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7662 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7663 silc_pkcs_load_[public/private]_key.
7665 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Added silc_server_get_route (route.[ch]) to get connection
7668 data for the fastest route for given ID.
7670 * Implemented INVITE command on client and server. The command
7671 were re-defined in the SILC Protocol Specification and the
7672 implementation now complies with the specification.
7674 * Implemented PING command on client and server.
7676 * Implemented NAMES command on client and server. The server side
7677 supports currently only normal server not router server yet.
7678 Some changes to NAMES definition in SILC protocol specification.
7680 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7682 * Implemented LEAVE command on client and server.
7684 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7685 again. This change was made to the protocol as well. Server
7686 should not violate the protocol specification anymore.
7688 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7690 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7691 was tested. SOCKS4 was not but should work anyway.
