1 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added functions silc_parse_version_string, silc_version_to_num,
4 and silc_ske_parse_version to parse SILC protocol style version
5 strings. Affected files lib/silcutil/silcutil.[ch] and
6 lib/silcske/silcske.[ch].
8 * Added new configuration params: version_protocol, version_software
9 and version_software_vendor to specify what version the remote
10 host must at least be to be able to connect to server. The vendor
11 string can be regex matched too. Added new function
12 silc_server_connection_allowed to check maximum number of allowed
13 connections, and allowed versions for incoming connections.
14 Affected files are silcd/server.c, server_util.[ch] and
17 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Added preliminary support for signals in scheduler. The
20 signals we care about are now blocked always when the scheduler
21 is locked. This way we can synchronise the use of signal with
22 scheduler. It is guaranteed that when signal occurs the scheduler
23 is not locked, and thus new tasks can be safely added to the
26 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
27 to silc_schedule_internal_init and silc_schedule_internal_uninit.
28 Added new platform specific routines
29 silc_schedule_internal_signals_[un]block and
30 silc_schedule_internal_signal_[un]register.
32 Added new functions to SILC Schedule API:
33 silc_schedule_signal_[un]register. Each signal that application
34 is going to use should be registered to the scheduler.
36 Affected files are lib/silcutil/silcschedule.[ch],
37 lib/silcutil/*/silc*schedule.c.
39 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
41 * Check for unauthenticated client and server in the
42 silc_server_new_client and silc_server_new_server functions.
43 Affected file silcd/packet_receive.c.
45 * Added function silc_string_is_ascii to check whether given
46 string is 7-bit ASCII string. Affected files are
47 lib/silcutil/silcutil.[ch].
49 * Added function silc_id_is_valid_server_id into the
50 silcd/serverid.c and added checking for valid Server ID's in
51 silc_server_new_server. The Server ID must always be based
52 on the server's public IP address.
54 * Added logging of DISCONNECT packet message in the server.
55 Affected file silcd/server.c.
57 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
59 * Changed all library interfaces that use Global RNG to also
60 accept SilcRng as argument. Affected files are
61 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
62 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
63 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
64 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
67 * Added function silc_pkcs_generate_key to the
68 lib/silccrypt/silcpkcs.[ch] for applications so that they
69 don't need to do pkcs->pkcs->init calls anymore.
71 * Remove SilcSocketConnection from the SFTP API since it really
72 wasn't needed there. The application has the information
73 saved in its contexts anyway and the SFTP layer doesn't need
74 know about it. Affected files lib/silcsft/silcsftp.h and
75 lib/silcsftp/sftp_[server/client].c.
77 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
78 The SilcSimContext is not SilcSim.
80 * Fixed possible buffer overflows in silc_id_render in the
81 lib/silcutil/silcutil.c.
83 * On EPOC the global crypto module lists are not used at all
84 in the crypto library. Added support for using the constant
85 algorithm list on EPOC. Affected files are
86 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
89 * Fixed the handling of third parameter of KICKED notify, since
90 it was mistakenly updated to SILC Protocol 1.0 even though it
91 is to be included in 1.1. Since it is not in 1.0 it is not
92 mandatory, and this fix now handles it only if it is provided,
93 and it is not error if it is not provided. Affected file
94 lib/silcclient/client_notify.c.
96 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
98 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
99 client. Affected file irssi/src/silc/core/client_ops.c.
101 * Merged with Irssi 0.8.4 from irssi.org CVS.
103 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>

106 sending any messages. Fixes a crash, but doesn't fix some
107 other underlaying bug that is lurking there. Affected
108 file silcd/packet_send.c.
110 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
112 * $usermode, $cumode and $cumode_space expandos shouldn't do
113 anything with non-SILC server records. Affected file
114 irssi/src/silc/core/silc-expandos.c
116 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
118 * Fixed the silc_net_check_[host/local]_by_sock to support
119 IPv6 bound sockets as well. Now they can return IPv6 addresses
120 as well. Affected file lib/silcutil/silcnet.c.
122 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
123 Affected lib/silcutil/unix/silcunixnet.c.
125 * Fixed ID rendering (at least on some platforms, not NetBSD)
126 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
128 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Added silc_hash_public_key and silc_hash_public_key_compare
131 functions to be used with SilcHashTable. They can be used to
132 hash public keys and compare public keys in hash table. Affected
133 file lib/silcutil/silcutil.[ch].
135 * Added support for specifying multiple public keys for Client
136 connection section in server configuration file. This makes it
137 possible to accept multiple public keys from same host, or to
138 make a section that accepts any incoming host, and have the
139 accepted public keys listed in the section.
141 Added functions silc_sever_[find/get]_public_key, added the
142 support for this actually to all connection sections but only
143 the Client section is currently allowed to specify multiple
146 Affected files are silcd/server.c, server_internal.h,
147 command.c, protocol.c, server_util.[ch], packet_receive.c.
149 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
151 * Merged Irssi 0.8.2 from irssi.org CVS.
153 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
155 * If silc_debug is TRUE, also output standard logging messages
156 to stderr with the debug output.
158 Made silc_log_reset_all() flushing all channels before returning.
159 Also fixed some documentation typos.
161 Affected files are lib/silcutil/silclog.[ch].
163 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
165 * Fixed the server to check correctly the amount of connections
166 from single host, by checking also the type of the connection.
167 Fixed also the comparison of number of connections and number
168 of allowed connections. Affected files are silcd/server.c,
171 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
173 * Fixed the USERS command reply to save the user's mode on the
174 channel as well. Fixed JOIN command reply to check whether a
175 client is on channel already and not join it twice. Affected
176 file lib/silcclient/command_reply.c.
178 * Added new file silc-expandos.c into irssi/silc/core/ to return
179 various stuff for various signal for the statusbar etc. updating.
180 Now Irssi SILC client prints channel user modes etc. on the
183 * The user mode (like server/router operator changes) is now shown
184 on the Irssi SILC client's statusbar. The affected files are
185 irssi/src/silc/core/client_ops.c, silc-expandos.c.
187 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

190 to SILC_SCHEDULE_[UN]LOCK macros.
192 * Added more error printing to logs in server code. Affected
193 files silcd/server.c and silcd/protocol.c.
195 * Fixed -S option parsing in Irssi SILC Client. Affected file
196 irssi/src/silc/core/silc-core.c.
198 * Added silc_buffer_alloc_size function. Affected file is
199 lib/silcutil/silcbuffer.h.
201 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
204 constants. Affected files in
205 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
208 * Changed the internal SFTP Memory FS table to const. Affected
209 file lib/silcsftp/sftp_fs_memory.c.
211 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
213 * Fixed the buffer formatting and unformatting routines to
214 check the size of 64 bits types with sizeof(). Affected
215 file is lib/silcutil/silcbuffmt.c.
217 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
219 * Removed 0.6.x backwards support.
221 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
223 * Changed all integer type names:
224 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
225 to avoid collisions with other libraries using same type names
228 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
230 * Added `prefer_ipv6' argument to the functions
231 silc_net_gethostbyname[_async]. If it is TRUE it will return
232 IPv6 address over IPv4. If FALSE IPv4 address is returned
233 even if IPv6 address was found. Affected files
234 lib/silcutil/silcnet.[ch].
236 * Added support silc_net_create_connection[_async] to fallback
237 to IPv4 address if IPv6 address could not be used (like if

249 * Added automatic extern "C" { ... } for C++ compilers so the
250 application does not need to define them. Affected file
251 includes/silcincludes.h.
253 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
254 old name went against naming convention. Applications now
255 include "silcclient.h" instead of "clientlibincludes.h".
256 Removed includes/clientlibincludes.h, it is redundant now.
258 * Renamed includes/version.h to silcversion.h.
260 * Added really preliminary support for OS/2 into the util
261 library. Only thread & mutex API is implemented, others
262 are still to be implemented. Created the lib/silcutil/os2/
263 directory. Created also file includes/silcos2.h.
265 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Added preliminary BeOS support into the util library.
268 Created lib/silcutil/beos/, and implemented all the needed

274 * Added proper initializations to silc's irssi code, so it's
275 now possible to load it as module. Affected files
276 irssi/src/silc/core/silc-core.c,
277 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

294 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
296 * Added `user_count' to the SilcChannelEntry which now tells the
297 number of users on the channel. The user count is now saved
298 in normal server of global channels as well. Affected files
299 silcd/server.c, idlist.h, packet_receive.c and command.c.
301 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
302 include file utility functions.
304 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
305 instead of calling directly OS routines.
307 * Fixed NICK change printing in Irssi SILC Client. Fixed
308 KICKED notify printing in Irssi SILC Client. Affected file
309 irssi/src/silc/core/client_ops.c.
311 * Fixed a NICK change bug in client library, to not recreate the
312 client_entry->channels hash table everytime nick is changed.
313 Affected file lib/silcclient/client.c.
315 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
317 * ROBOdoc documented the lib/silcske/silcske.h, and improved
318 the SKE interface a bit.
320 * Fixed padding problem in PKCS#1. The padding was not actually
321 random since the random number generator was used incorrectly.
322 This security bug affects only when encrypting with PKCS#1, and
323 it is not currently used at all in SILC. SILC only use signing
324 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
326 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

375 section structs, now identifying the param directly.
377 Added CONFIG_FREE_AUTH macro in config file parsing.
379 Affected files are silcd/serverconfig.[ch].
381 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>

384 is now done in silc_core_init() which also fixes autoconnecting
387 Affected files irssi/src/silc/core/silc-core.c,
388 irssi/src/fe-text/silc.c.
390 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Added new configuration options and blocks:
393 keepalive_secs, reconnect_count, reconnect_interval,
394 reconnect_interval_max, reconnect_keep_trying and
395 require_reverser_lookup. Added ConnectionParam block, and
396 implemented the connection parameters when connecting as
397 initiator and when accepting connections as responder.
399 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
400 whether given configuration value has been given already.
402 Affected files silcd/serverconfig.[c], server.[c].
404 * Splitted the doc/example_silcd.conf.in. Separated the crypto
405 algorithm parts and created new file silcalgs.conf, that
406 is now included from the example_silcd.conf.in.
408 * Optimized the silc_server_connect_to_router_second to take
409 the connection configuration object from the SilcServerConnection
410 object instead of finding it during the connecting phase.
411 Added the configuration object to SilcServerConnection struct.
412 Affected files silcd/server_internal.h, server.c.
414 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
416 * Add the client on channel after it was resolved at the
417 channel message receiving, and it was not already on the
418 channel. Affected file lib/silcclient/client_channel.c.
420 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
422 * Fixed the public key authentication to allocate always the
423 destination signature buffer instead of using static buffer.
424 Affected file silcd/protocol.c.
426 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
428 * Unified the serverconfig.[ch]'s helper function interface.
429 Affected file silcd/serverconfig.[ch].
431 * Removed doc/example_silc.conf.in since it is redundant.
432 The make install will now install irssi/silc.conf file.
434 * Added new Passphrase and Publickey authentication methods to
435 config file, allowing both public key and passphrase based
436 authentication to be set at the same time.
438 Added `prefer_passphrase_auth' setting in config file which
439 can be used to set to prefer passwd auth if both passwd and
440 public key is set. If not set, public key is preferred.
441 This has effect only when being initiator (responder will try
444 Added support for authentication with passphrase and public key
445 at the same time. The passphrase is tried first always since
446 it is faster to check.
448 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
450 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

496 * Fixed the file transfer's key agreement payload to include
497 zero port also if the hostname is NULL because it could not
500 Call file transfer monitor callback now also if error occurs
501 during key agreement protocol.
503 Changed the silc_client_file_send interface to return the
504 SilcClientFileError instead of session id. The session ID
505 is returned into pointer provided as argument.
507 Check that the file exists locally before sending the
508 file transfer request at all.
510 Affected file lib/silcclient/client_ftp.c, silcapi.h.
512 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
513 error than can occur while key agreement protocol. Affected

522 file lib/silcutil/silclog.c.
524 * Fixed the channel message payload decryption in the function
525 silc_channel_message_payload_decrypt to not modify the original
526 buffer before it is verified that the message decrypted
527 correctly. Otherwise, next time it is called with correct
528 channel key it won't encrypt since the payload is corrupted.
529 Affected file lib/silccore/silcchannel.c.
531 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

543 * Fixed a bug in hash table internal routine for traversing
544 the table with foreach callback. The current entry may
545 become invalid in the callback but it was referenced after
546 the callback returned.
548 Do not allow auto rehashing of hash table during the
549 silc_hash_table_foreach operation, for same reasons as it is
550 not allowed for SilcHashTableList. Affected files are
551 lib/silcutil/silchashtable.[ch].
553 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
555 * Defined DLLAPI into silcincludes.h and silcwin32.h for
556 Win32 DLL. extern's in header files are now declared with
559 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
561 * Fixed private message handling. It used some old code that
562 caused the client to crash. Affecte file is
563 lib/silcclient/client_prvmsg.c.
565 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
567 * Added function silc_client_add_channel,
568 silc_client_replace_channel_id, and removed functions
569 silc_client_new_channel_id and silc_idlist_get_channel_by_id
572 * Added cross reference of the joined channels to the
573 SilcClientEntry, and changed the SilcChannelEntry's
574 users list to SilcHashTable. The affected files are
575 lib/silcclient/idlist.[ch].
577 * Fixed a bug in hash table tarversing. While the hash table
578 is traversed with SilcHashTableList the table must not be
579 rehashed. It is now guaranteed that auto rehashable tables
580 are not rehashed while tarversing the list. Also defined that
581 silc_hash_table_rehash must not be called while tarversing
582 the table. Added function silc_hash_table_list_reset that must
583 be called after the tarversing is over. The affected files are
584 lib/silcutil/silchashtable.[ch].
586 * Changed all hash table traversing to call the new
587 silc_hash_table_list_reset in server and in client library.
589 * Added function silc_client_on_channel to return the
590 SilcChannelUser entry if the specified client entry is joined
591 on the specified channel. This is exported to application as
592 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
594 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
596 * Fixed founder regaining problem with JOIN command on normal
597 server. The notify for mode change must be sent always and
598 not only if !cmd->pending. Affected file silcd/command.c.
600 * Fixed the WHOWAS command's reply sending to support the
601 lists correctly. Affected file silcd/command.c.
603 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
605 * When sending JOIN command to router for processing the
606 sender's old command identifier was not saved back to the
607 sender's command context, fixed now. The affected file is
610 * Create the key in JOIN command of the router did not return
611 the channel key, added check for this. Affected file is
614 * Fixed a channel ID update bug in JOIN command reply. Do
615 not directly upgrade the ID but call the function
616 silc_idlist_replace_channel_id if the ID was changed.
617 Affected file silcd/command_reply.c.
619 * Fixed memory leaks from command calling if it would fail.
620 Affected file silcd/command.c.
622 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
624 * Applied patches from cras:
626 Memory leak fixes around libaries, irssi window resize fix,
627 new silclist.h and silcdlist.h, all extern inline changed to
630 * Removed dotconf from lib/dotconf, not needed anymore.
632 * Removed TRQ from lib/trq, not needed anymore.
634 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
635 with server connections. Later this will be configurable
636 in config file after new config file is done. Affected file
639 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
641 * Fixed a crash in server related to channel announcements.
642 Affected file silcd/server.c.
644 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
646 * Fixed memory leaks in silc_server_create_new_channel*
647 functions. Affected file silcd/server.c.
649 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
650 which ID was changed. This way the router will send the
651 user list for the channel again, and server won't be in
652 desync in some rare circumstances. Affected file is
653 silcd/packet_receive.c.
655 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
657 * Check for NULL socket pointer in the function
658 silc_server_packet_send_to_channel_real. Affected file
661 * Fixed the BAN notify handling to correctly remove ban
662 list. Affected file silcd/packet_receive.c.
664 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Fixed some header addition to Toolkit distribution in
667 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
669 * Added lib/silcclient/client_ops_example.h as an template
670 file for application programmers to quickly start using
671 the SilcClientOperation functions in their application.
672 Updated the lib/silcclient/README as well to tell about this
673 nice file made available.
675 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
677 * Call silc_server_remove_from_channels when removing client
678 entry when NO_SUCH_CLIENT_ID was received. Affected file
679 is silcd/command_reply.c.
681 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
683 * Added server & router operator statistics updating. Affected
684 file silcd/packet_receive.c and silcd/command.c.
686 * Fixed the SERVER_SIGNOFF notify handling on normal server
687 not to save the history information for clients. Same was
688 fixed earlier in remove_clients_by_server function, but not
689 here. Affected file silcd/packet_receive.c.
691 * Raised the default connection-retry count from 4 to 7 in
692 server. Affected file silcd/server.h.
694 * Cancel any possible reconnect timeouts when we start the
695 key exchange. Affected file silcd/server.c.
697 * Do not reconnect on connection failure when SCONNECT was
698 given. Affected files silcd/server.[ch].
700 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
702 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
704 * Fixed the NICK command to always give the unformatted
705 nickname to the one giving the NICK command. If unformatted
706 nickname is cached already it will be formatted and the
707 local entry will always get the unformatted nickname.
708 Affected file lib/silcclient/idlist.c.
710 * Fixed some double frees from client library commands.
711 Affected file is lib/silcclient/command.c.
713 * Fixed CUMODE command in server to assure that no one can
714 change founder's mode than the founder itself, there was a
715 little bug. Affected file silcd/command.c.
717 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
719 * Removed the SilcClientCommandDestructor from the client
720 libary, it is not needed anymore. Affected files are
721 lib/silcclient/silcapi.h, command[_reply].[ch],
722 client_notify, idlist.c.
724 * Fixed GETKEY command to first resolve client, and then
725 resolve the server only if the client was not found, instead
726 of resolving both at the same time. Affected file is
727 lib/silcclient/command.c.
729 * Added silc_client_start_key_exchange_cb and lookup the
730 remote hostname and IP address before starting the key
731 exchange with server. The affected file is
732 lib/silcclient/client.c.
734 * The server's public key is now saved using the IP address
735 of the server and not the servername for the filename.
736 The hostname public key filename is checked as an fall back
737 method if the IP address based filename is not found.
739 Fixed the GETKEY command to save the fetched server key
742 Print the remote server's hostname now when new key is
743 received during connection process. Affected file is
744 irssi/src/silc/core/client_ops.c.
746 * Return always our own public key to the client if it asks
747 for it with GETKEY command. Affected file silcd/command.c.
749 * Removed the use_auto_addr variable from default config
750 file since it was in wrong section. Affected file is
753 * Fixed TOPIC_CHANGE notification to not route it when it
754 was sent using silc_server_send_notify_to_channel function.
755 Affected file silcd/command.c.
757 * Fixed silc_server_send_notify_kicked to send the kicker's
758 Client ID also, it was missing. Affected files are
759 silcd/command.c, silcd/packet_send.[ch].
761 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
763 * Do not save client history information in SERVER_SIGNOFF.
764 Fixes the bug in normal server that it does not detect
765 the client becoming valid after the server becomes back
766 online. Affected file silcd/server_util.c.
768 * Added `sock_error' field into the SilcSocketConnection
769 context. When error occurs during socket operation (read
770 or write) the error is saved. Added also new function
771 silc_socket_get_error to return human readable socket error
772 message. Affected files are lib/silcutil/silcsockconn.[ch],
773 lib/silcutil/unix/silcunixsockconn.c, and
774 lib/silcutil/win32/silcwin32sockconn.c.
776 * The server now prints the socket error message in the
777 signoff for client. Affected file silcd/server.c.
779 * Fixed the `created' channel information sending from router
780 to server in JOIN command. Checks now whether the channel
781 really was created or not and set it according that.
783 Fixed the JOIN command to use the client entry's current
784 ID during the joining procedure instead of the one it sent
785 in the command (it is checked though), since it can change
786 between the packet processing and command processing, and
787 would just case unnecessary pain in the client end. Affected
788 file silcd/command.c.
790 * Fixed a channel key payload sending to use correct channel
791 ID when the server was forced to change the channel's ID by
792 router. Router sent the key payload with the old Channel ID.
793 Affected file silcd/packet_receive.c.
795 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Call silc_server_save_channel_key only if the key payload
798 was provided in the JOIN command's command reply. Affected
799 file silcd/command_reply.c.
801 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Fixed silc_mp_sizeinbase to return the value correctly with
804 MPI. Affected file lib/silcmath/mp_mpi.c.
806 * Fixed the stop_server signal to correctly stop the scheduler
807 and gracefully stop the server when SIGTERM or SIGINT signals
808 are received. Affected file silcd/silcd.c.
810 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
812 * Simple handling of TERM and HUP signals. Also added some log
813 flushing call around. Affected file is
816 * Fixed small bugs in silclog.c. Now buffering output will take
817 effect after 10 seconds since startup: This will ensure that
818 no important startup messages are lost. Also output redirection
819 will preserve original format ([Date] [Type] message).
820 Affected file is lib/silcutil/silclog.c.
822 * Added two options to the config file, in the logging section:
823 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
824 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
826 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
828 * Do not print the warning about log files not being initialized
829 more than once to avoid excess logging. Affected file is
830 lib/silcutil/silclog.c.
832 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
833 the SIM copying in make install in Makefile.am.pre.
835 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
837 * Rewritten silclog APIs. Globally interesting changes follows:
838 silc_log_set_files() changed to silc_log_set_file().
839 silc_log_set_callbacks() changed to silc_log_set_callback().
840 ROBOdoc documented silclog header file.
841 SilcLogCb now returns bool to wether inihibit the default
842 handler or not (to keep the old behaviour return always TRUE).
843 The new APIs should also fix the problem of the
844 silcd_error.log file that was written in the current directory.
847 Log files streams will remain opened after silc_log_set_file()
848 call, means less CPU usage notably on high traffic servers.
849 File streams are now full buffered, and flushed to the disk
850 every 5 minutes, lesses HD activity and CPU usage.
851 Messages can be redirected, allowing admins to configure
852 one single logfile for all server messages.
853 the silc_log_quick global variable to activate fast-logging.
854 Affected files lib/silcutil/silclog.[ch]
856 * Changed some code to conform new silclog APIs. Affected
857 files are doc/example_silcd.conf.in, silcd/server.c
858 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
861 * Fixed a memory leak that could occur in some situations.
862 Affected file silcd/serverconfig.c.
864 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
866 * Added the silc_client_del_client to remove the client from
867 all channels as well. Affected file lib/silcclient/idlist.c.
869 * Fixed the client library to correctly remove the client
870 from all channels when the client entry is being destroyed.
871 Affected file lib/silcclient/client_notify.c, command.c.
873 * Added auto-nicking support to the client library. If the
874 applicatio now sets client->nickname it will be sent to the
875 server after connecting by the library. This way for example
876 SILCNICK (or IRCNICK) environment variables will have effect
877 and always change the nickname automatically to whatever
878 it is wanted. Affected file lib/silcclient/client.[ch].
880 * Renamed silc_server_command_bad_chars to the
881 silc_server_name_bad_chars and moved it to the
882 silcd/server_util.[ch]. Added also new function
883 silc_server_name_modify_bad to return nickname that
884 includes bad characters as new nickname without those
885 bad characters. This check and modify is now used in
886 silc_server_new_client when the username is initially set
887 as nickname, so it must be checked to be valid nickname.
888 Affected file silcd/packet_receive.c.
890 * The nickname length is now taken from the packet for real
891 and not trusted to strlen() since it clearly can return
892 wrong length for nickname including bad characters. This
893 also applies to channel names. Affected file silcd/command.c.
895 * Removed the lib/silcsilm/modules directory. Modules are now
896 compiled into the lib/silcsim. Fixed the copying of the
897 modules to follow symbolic links in Makefile.am.pre.
899 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * Fixed silc_string_regexify list creation. Fixes bugs with
902 BAN and INVITE commands in server. The affected file is
903 lib/silcutil/unix/silcunixutil.c.
905 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Removed the command destructor entirely from the server's
908 command and command reply routines. It is not needed, and
909 its usage was buggy and caused crashes. Affected files are
910 silcd/command[_reply].[ch].
912 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Cancel protocol and NULL sock->protocol if timeout
915 occurred during protocol. Affected file silcd/server.c.
917 * Cancel protocol timeouts always before calling the final
918 callback, to assure that after final callback is called
919 no other state will be called for the protocol anymore.
920 Affected file silcd/protocol.c.
922 * Print error log if incoming connection configuration could
923 not be found. Affected file silcd/server.c.
925 * Fixed JOIN command to correctly save the founder mode
926 to the client on normal SILC server, when the channel
927 was created by the router. Affected file silcd/command.c.
929 * Fixed LIST command (hopefully) to send correct reply
930 packets. Affected file silcd/command.c.
932 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
934 * The silc_packet_receive_process now returns FALSE if the
935 read data was invalid packet, and TRUE if it was ok.
937 The server now checks that if unauthenticated connection
938 sends data and its processing fails the server will close
939 the connection since it could be a malicious flooder.
941 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
943 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Make sure the warning about error opening a log file is
946 printed only once and not everytime it fails (produces
947 too much useless log). Affected file lib/silcutil/silclog.c.
949 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
951 * Made the silc_server_daemonise() function more readable.
952 Affected file silcd/server.c.
954 * Pid file is now optional, the user may comment it out from
955 the config file. Removed define SILC_SERVER_PID_FILE, we
956 don't need a default any longer. Affected file
957 configure.in.pre, lib/Makefile.am.pre.
959 * Make some use of the pid file. The server now dies at startup
960 if it detects a valid pid file on his path. The server would
961 die anyway in this circumstance, because of the bind() failure.
962 Affected file silcd/silcd.c.
964 * No longer compiling lib/dotconf.
966 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
968 * Fixed JOIN command parsing not to crash. Affected file
969 lib/silcclient/command.c.
971 * Fied the NICK_CHANGE notify to add the new client entry
972 even it is resolved. This removes an <[unknown]> nick
973 thingy bug in the client. Affected file is
974 lib/silcclient/client_notify.c.
976 * Do not try to allocate 0 bytes (efence does not like it)
977 in lib/silccore/silccomand.c when encoding payload.
979 * Do not take IRCNICK as nickname in Irssi SILC client since
980 it is not possible to set nickname before hand connecting
981 the server (TODO has an entry about adding auto-nicking
984 * Changed the silc_server_command_pending to check whether
985 there already exists an pending entry with the specified
986 command, command identifier and pending callback. This is
987 to fix IDENTIFY and WHOIS related crashes that may register
988 multiple pending commands with same identifier. Affected
989 file silcd/command.c.
991 * Fixed the server to reconnect to the router even if it
992 was already reconnecting and EOF was received. This to
993 fix a possibility that the server wouldn't ever try to
994 auto-reconnect to the router. Affected file silcd/server.c.
996 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
998 * Fixed the server's password authentication to use the
999 length of the locally saved password, and not the one
1000 sent in the packet. Affected file silcd/protocol.c.
1002 * Fixed same password authentication problem in the
1003 Authentication Payload handling routines in
1004 lib/silccore/silcauth.c.
1006 * Yet another password authentication problem fixed with
1007 channel password handling in silcd/command.c.
1009 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1011 * If first character of string in silc_parse_userfqdn is '@'
1012 then do not parse it. Affected file is
1013 lib/silcutil/silcutil.c.
1015 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Fixed minor bug in IDENTIFY command reply sending, which
1018 caused various weird problems during JOIN when it was
1019 resolving names for users. Affected file silcd/command.c.
1021 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Fixed the IDENTIFY command reply sending to chech better valid
1024 clients. It was possible to send incomplete list of replies.
1025 Affected file silcd/command.c.
1027 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * Added silc_client_command[s]_[un]register functions now to
1030 dynamically register the commands in client library. Removed
1031 the static table of commands. This allows the client library
1032 to call commands without causing the application to know about
1033 what commands library has called.
1035 Removed the INFO command reply kludge to detect when the command
1036 was called by library. Now library use its own command reply
1037 function for INFO command.
1039 Added function silc_client_command_call to call a command.
1040 Application can use it to call command, not access the structure
1043 Now all commands that are sent by the client library (not
1044 explicitly sent by application) use own command reply functions.
1046 Affected files around lib/silcclient/ and in
1047 irssi/src/silc/core/.
1049 * Fixed the WHOIS command reply sending to chech better valid
1050 clients. It was possible to send incomplete list of replies.
1052 Fixed the WHOIS and IDENTIFY to send the request to router
1053 if normal server did not do it and did not find any results.
1055 Affected file silcd/command.c.
1057 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Moved the internal data from SilcClient context into its
1060 own file, not accesible to application. Affected files
1061 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1062 and other files in client library.
1064 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Added doc/examples installation target in Makefile.am.pre.
1069 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1072 commands the found client entry will be removed from the
1073 cache, after notifying application about the error. Affected
1074 file lib/silcclient/command_reply.c.
1076 * Changed the /MSG to check for exact nickname user gave, and
1077 not let `nick' match `nick@host' if it is only one found. Now,
1078 user must type the exact nickname (like nick@host2) even if
1079 there are no more than one same nicks found. This is to avoid
1080 a possibility of sending nickname to wrong nickname since
1081 `nick' could match `nick@host'. Affected file is
1082 irssi/src/core/silc-servers.c.
1084 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * Do not print "you are now server operator" or similar when
1087 giving /away command. Affected files are
1088 irssi/src/silc/core/client_ops.c, silc-servers.h.
1090 * Made the silc_server_command_pending_error_check to send
1091 the same command reply payload it received back to the
1092 original sender of the command. This way all arguments
1093 that was received by the server will be received by the
1094 client too. Affected file silcd/command.c.
1096 * Added the silc_idcache_add to return the created cache entry
1097 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1099 * Add global clients to expire if they are not on any channel.
1100 This is because normal server will never know if they signoff
1101 if they are not on any channel. The cache expiry will take
1102 case of these entries. This is done by normal servers only.
1103 The affected files are silcd/command_reply.c,
1104 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1106 * If server receives invalid ID notification for WHOIS or
1107 IDENTIFY and the ID exists in the lists, it is removed.
1108 Affected file silcd/command_reply.c.
1110 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1111 in client then client entry that it matches is searched and
1112 the nickname is printed on the screen for user. Affected
1113 file irssi/src/silc/core/client_ops.c.
1115 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1117 * Use cache entry expire time in the LIST command reply to
1118 purge old entries from the cache after the LIST command
1119 reply has been received. This way we don't have non-existent
1120 entries in the cache for too long. Affected file is
1121 silcd/command_reply.c.
1123 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * If we are normal server, and we've not resolved client info
1126 in WHOIS or IDENTIFY from router, and it is global client,
1127 we'll check whether it is on some channel. If it is not
1128 then we cannot be sure about its validity and will resolve it
1129 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1130 file silcd/command.c.
1132 * Search channel by name (if possible) rather than by ID
1133 in IDENTIFY command's command reply. Affected file is
1134 silcd/command_reply.c.
1136 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1139 Updated specs and implemented it. Affected file silcd/command.c,
1140 silcd/packet_send.c and silcd/packet_receive.c.
1142 * Implemented the <founder auth> payload handling in the JOIN
1143 command. If provided all conditions for channel joining
1144 except requirement to provide correct passphrase can be
1145 overrided by the channel founder. Updated the protocol specs.
1146 Affected file silcd/command.c.
1148 Added support for founder auth in JOIN command in client
1149 library. Fixed the parsing of the JOIN command now to support
1150 all options as they should be. The affected file is
1151 lib/silcclient/command.c.
1153 * Optimized the WHOIS and IDENTIFY commands to send the request
1154 to router only if it includes nicknames or other names. If
1155 they include only IDs then check the local cache first before
1156 routing. Affected file is silcd/command.c.
1158 * Added channels topic announcements. Affected file is
1159 silcd/packet_receive.c and silcd/server.c.
1161 * Fixed the silc_server_send_notify_topic_set to really destine
1162 the packet to channel. Affected file silcd/packet_send.c.
1164 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1165 library. Affected file lib/silcclient/client_notify.c.
1167 * Added UMODE announcements. Affected file silcd/server.c.
1169 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Memory leak fixes in:
1173 lib/silcutil/silcsockconn.c
1174 lib/silcske/silcske.c
1175 lib/silcske/groups.c
1177 lib/silccrypt/silcpkcs.c
1178 lib/silccore/silccommand.c
1179 lib/silccore/silcidcache.c
1184 * ROBOdoc documented the lib/silcske/groups.h file and a
1185 bit changed the interface for better.
1187 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1189 * Update the client entry context in the ID cache after
1190 nick change. Affected file lib/silcclient/command.c.
1191 Fixes the CUMODE command when regaining founder privileges,
1192 and a little WHOIS problem.
1194 * Fixed silc_net_gethostbyname to correctly call the
1195 inet_ntop. Affected file lib/silcutil/silcnet.c.
1197 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1199 * Added IPv6 support checking to the configure.in.pre, added
1200 also --enable-ipv6 option to override the check. Affected
1201 file configure.in.pre.
1203 * The silc_thread_create now calls the start function
1204 directly if threads support is not compiled in. Removes
1205 ugly #ifdef's from generic code. Affected files are
1206 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1208 * Added silc_net_gethostby[name/addr]_async to asynchronously
1209 resolve. Affected files are lib/silcutil/silcnet.[ch].
1211 * Added support for rendering IPv6 based server, client and
1212 channel IDs. Affected file lib/silcutil/silcutil.c.
1214 * Added support for creating IPv6 based server IDs. Affected
1215 file is silcd/serverid.c.
1217 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1219 * Added silc_net_gethostby[addr/name] into the
1220 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1221 routines. Added silc_net_is_ip[4/6]. Affected file is
1222 lib/silcutil/unix/silcunixnet.c. All routines that take
1223 address as argument now supports both IPv4 and IPv6 addresses.
1225 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1227 * Fixed LIST command reply sending in server. Affected file
1230 * Server now sends the kicker's client ID in the KICK notify
1231 to the kicked client. Affected file silcd/command.c.
1233 * The client library now parses the kickers client ID and
1234 UI displays it. Affected files lib/silcclient/client_notify.c
1235 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1237 * Made all payload parsing function prototypes consistent.
1238 They all take now const unsigned char * and uint32 pair as
1239 the payload data instead of SilcBuffer. Changes all around
1240 the source tree. Other unsigned char* -> const unsigned char*
1241 changes around the tree as well.
1243 * Optimized SFTP client and server packet sending not to
1244 allocate new buffer for each packet but to recycle the
1245 first allocated buffer. Affected files are
1246 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1248 * Optimized the SFTP client to use SilcList instead of
1249 SilcDList for requests, because it is faster. Affected file
1250 is lib/silcsftp/sftp_client.c.
1252 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1253 into lib/silccore/silcid.[ch].
1255 Renamed silcpayload.[ch] into silcargument.[ch].
1257 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * If client entry is deleted with active key agreement
1260 session, abort the session.
1262 The silc_client_abort_key_agreement now calls the completion
1263 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1265 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1268 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Don't use __restrict in older GCC's. Affected file is
1271 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1273 * silc_net_localhost now attempts to reverse lookup the
1274 IP/hostname. Affected file lib/silcutil/silcnet.c.
1276 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1277 command. It can be used to gain founder privileges at
1278 the same time when joining the channel.
1280 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1281 kicker's client ID as well. Updated protocol specs.
1283 Defined that the server must send SILC_COMMAND_IDENTIFY
1284 command reply with error status to client who sent
1285 private message with invalid client ID.
1287 Updated the protocol specification.
1289 * Added silc_server_send_command_reply to send any
1290 command reply. Affected file silcd/packet_send.[ch].
1292 * Added silc_id_payload_encode_data to encode ID payload
1293 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1295 * The server now send IDENTIFY command reply with error
1296 status if client ID in private message is invalid. Affected
1297 file silcd/packet_receive.c.
1299 * Save the server key file with server's IP address in
1300 the filename instead of hostname. The affected file is
1301 irssi/src/silc/core/client_ops.c.
1303 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1305 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1308 * Added libtool support for compiling shared objects in
1309 lib/silcsim. Affected file configure.in.pre and
1310 lib/silcsim/Makefile.am. Original patch by cras.
1312 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Pid file configuration, and server's config file fixes
1315 patch by toma. Updated CREDITS file.
1317 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Fixed silc_client_channel_message to not try to decrypt
1320 the message twice if it resolved the destination client
1321 information. This could cause of dropping one channel
1322 message. Affected file lib/silcclient/client_channel.c.
1324 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1327 lib/silcclient/client.c. This function is used when the SILC
1328 Client is run under some other scheduler, or event loop or
1329 main loop. On GUI applications, for example this may be
1330 desired to used to run the client under the GUI application's
1331 main loop. Typically the GUI application would register an
1332 idle task that calls this function multiple times in a second
1333 to quickly process the SILC specific data.
1335 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1337 * Fixed silc_server_drop() for dropping the supplementary
1338 groups as well, this could cause a security hole on some
1341 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1346 * Write PID file after dropping privileges. Added -F option
1347 to run server on foreground. A patch by debolaz.
1348 Affected files silcd/server.c, silcd/silcd.c.
1350 * Fixed MOTD to return the MOTD file server name. Affected
1351 file silcd/command.c.
1353 * Added INFO command reply handling to the Irssi SILC Client.
1354 Affected file irssi/src/silc/core/client_ops.c.
1356 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed the silc_idcache_list_* routines to really support
1359 the dynamic list. Fixes a crash. Affected file is
1360 lib/silccore/silcidcache.c.
1362 * Fixed the LIST command reply to really call LIST command's
1363 pending callbacks. Affected file silcd/command_reply.c.
1365 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1367 * Update conn->local_entry->nickname after giving NICK
1368 command. Affected file lib/silcclient/command.c.
1370 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1372 * Added the [pid] option to the silcd configuration file
1374 Affected files: serverconfig.[ch] and silcd.c
1376 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Save fingerprint in WHOIS command reply in server.
1379 Affected file silcd/command_reply.c.
1381 * Fixed NICK commands pending callback registration.
1382 Affected file lib/silcclient/command.c.
1384 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Use ++server->cmd_ident when sending commands in server,
1387 instead of random number. Affected file silcd/command.c.
1389 * Fixed GETKEY command reply to call actually GETKEY pending
1390 command callbacks. Affected file silcd/command_reply.c.
1392 * A bit stricter check for nicknames. Check for same nickname
1393 in NICK command also. Affected file silcd/command.c.
1395 * Do not call INFO command everytime client ID changes, only
1396 during first connecting. Affected file lib/silcclient/client.c.
1398 * Set the new nickname only after successful command reply for
1399 NICK command is returned by server. Affected file
1400 lib/silcclient/command.c.
1402 * Remove nicknames from nicklist during server_signoff notify.
1403 Should fix /NAMES bit more. The affected file is
1404 irssi/src/silc/core/silc-channels.c.
1406 * Added `fingerprint' field to the SilcIDListData in the
1407 silcd/idlist.h to hold the fingerprint of the client's
1410 Send the fingerprint of the client's public key in WHOIS
1413 Affected files silcd/command.c, and silcd/idlist.[ch].
1415 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1416 create fingerprint from given data.
1418 * Show the fingerprint of the client's public key in WHOIS.
1419 Affected files irssi/src/module-formats.[ch] and
1420 irssi/src/silc/core/client_ops.c.
1422 * Format the multiple same nicknames also during JOIN and
1423 NICK_CHANGE notifys. Affected file is
1424 lib/silcclient/client_notify.c.
1426 * Do not print error on screen for invalid private message
1427 payload since it can come if someone is sending private
1428 messages with wrong key. Affected file
1429 lib/silccore/silcprivate.c.
1431 * Fixed multiple concurrent /PING crash. Affected file
1432 lib/silcclient/command.c.
1434 * Changed the wrong ID encoding. All IP addresses must be
1435 in MSB first order in encoded format. They were encoded
1436 wrong and was in LSB format. Affected files are
1437 silcd/serverid.c, lib/silcutil/silcutil.c.
1439 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1441 * Call the `connect' client operation through the scheduler
1442 in case of error. Affected file lib/silcclient/client.c.
1444 * Call the `failure' client operation even if the error
1445 occurred locally during a protocol. Affected file is
1446 lib/silcclient/protocol.c.
1448 * Added support of sending LIST command to router from normal
1449 server. This way normal server can get list of all channels
1450 in the network too. Fixed the channel list sending in the
1451 server too. Affected files are silcd/command.c, and
1452 silcd/command_reply.[ch].
1454 * Added silc_server_update_channels_by_server and
1455 silc_server_remove_channels_by_server. They are used during
1456 disconnection of primary router and in backup router protocol.
1457 Affected file silcd/server_util.[ch], silcd/server.c and
1458 silcd/server_backup.c.
1460 * Fixed channel adding to global list in IDENTIFY command
1461 reply in server. Affected file silcd/command_reply.c.
1463 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * If the incoming packet type is REKEY or REKEY_DONE process
1466 that packet always synchronously. Fixes yet another MAC
1467 failed error on slow (dialup) connections. Affected file
1468 lib/silcclient/client.c and silcd/server.c.
1470 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Call check_version SKE callback for initiator too. Affected
1473 file lib/silcske/silcske.c.
1475 * Implemented fix for security hole found in the SKE that was
1476 fixed in the specification few days back; the initiator's
1477 public key is now added to the HASH value computation.
1478 Added backwards support for the old way of doing it too, for
1479 old clients and old servers. Affected file is
1480 lib/silcske/silcske.c.
1482 * Enabled mutual authentication by default in SKE. If initiator
1483 is not providing mutual authentication the responder will
1484 force it. This will provide the proof of posession of the
1485 private key for responder. The affected files are
1486 lib/silcclient/protocol.c and silcd/protocol.c.
1488 * Do not cache anymore the server's public key during SKE.
1489 We do mutual authentication so the proof of posession of
1490 private key is done, and if the server is authenticated in
1491 conn auth protocol with public key we must have the public
1492 key already. Affected file silcd/protocol.c.
1494 * Added new global debug variable: silc_debug_hexdump. If
1495 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1496 file lib/silcutil/silclog.[ch].
1498 * Fixed compilation warning due to char * -> const char *.
1499 Affected files lib/silcutil/silcnet.h, and
1500 lib/silccore/silcauth.[ch].
1502 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Fixed CMODE command when new channel key was created. If
1505 the creation failed the old key was removed. Next time giving
1506 same command would crash the server since the old key was
1507 freed already. Affected file silcd/command.c.
1509 * Fixed the silc_server_announce_get_channels to not crash
1510 on reconnect. Affected file silcd/server.c.
1512 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Added silc_log_set_debug_string function to set a regex
1515 string to match for debug output. Only the function names,
1516 or filenames matching the given debug string is actually
1517 printed. This way it is possible to filter out those debug
1518 strings that user is not interested in.
1520 Fixed a bug in silc_string_regexify.
1522 Affected files lib/silcutil/silclog.[ch], and
1523 lib/silcutil/unix/silcunixutil.c.
1525 * Changed the -d options in both server and Irssi SILC client
1526 to take the debug string as argument. Affected files
1527 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1529 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Added silc_hash_babbleprint to create a Bubble Babble
1532 Encoded fingerprint. The encoding is developed by Antti
1533 Huima (draft-huima-babble-01.txt), and it creates human
1534 readable strings out of binary data. Affected file
1535 lib/silccrypt/silchash.[ch].
1537 * Print the babble print now in addition of fingerprint as well
1538 in Irssi SILC client. Affected files are
1539 irssi/src/fe-common/silc/module-formats.[ch],
1540 irssi/src/fe-common/silc/core/client_ops.c.
1542 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Fixed a security problem found in SKE. The initiator's
1545 public key too is now added to the HASH hash value creation
1546 which is signed by the responder to create the SIGN value.
1547 This will prevent anyone in the middle to lie to the responder
1548 about the initiator's public key. If this is done now, the
1549 man in the middle will get caught. Updated the protocol
1552 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Better installation directory handling. Configure module
1555 paths and other paths automatically to example_silc* files
1556 in doc/. A patch by toma.
1558 * Fixed compiler warning from MPI library, and from SILC RNG.
1561 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1562 It can be configured with ./configure. A patch by toma.
1564 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * Find correct make to use in prepare-clean. A patch by
1567 toma. Affected file prepare-clean.
1569 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1571 * Added irssi variables use_auto_addr, auto_bind_ip,
1572 auto_bind_port and auto_public_ip.
1574 * Changed the interface for silc_client_send_key_agreement
1575 in lib/silcclient/silcapi.h
1579 irssi/src/silc/core/silc-core.c
1581 lib/silcclient/silcapi.h
1582 irssi/src/silc/core/silc-channels.c
1583 lib/silcclient/client_keyagr.c
1586 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Added silc_pkcs_public_key_compare to compare two
1589 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1591 * Check that the client who set the founder mode on the
1592 channel is the same client that is giving the founder
1593 mode to itself. It is done by comparing the saved public
1594 key (it is saved even in the authentication is passphrase).
1595 Affected file silcd/command.c.
1597 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * Do not process packet for disconnected socket connection.
1600 Affected file lib/silccore/silcpacket.c.
1602 * Process the DISCONNECT packet through scheduler in the
1603 client library. Affected file lib/silcclient/client.c.
1605 * Fixed the silc_client_packet_parse to not to increase
1606 the packet sequence number if the conn->sock and the
1607 current socket connection is not same. This can happen
1608 for example during key agreement when the conn includes
1609 multiple socket connections (listeners). Affected file
1610 lib/silcclient/client.c.
1612 * The sender of the file transfer request now provides also
1613 the pointer (listener) for the key exchange protocol. If
1614 the listener cannot be created then it sends empty key
1615 agreement and lets the receiver provide the listener.
1617 Added `local_ip' and `local_port' arguments to the
1618 silc_client_file_send. If they are provided they are used,
1619 if not then it will attempt to find local IP address, if
1620 not found or bind fails then the remote client will provide
1623 Affected files are lib/silcclient/client_ftp.c and
1624 lib/silcclient/silcapi.h.
1626 * Extended the FILE SEND command to support defining the
1627 local IP and port for key exchange listener. They are
1628 optional. Affected file irssi/src/silc/core/silc-servers.c.
1630 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Defined to WHOIS command reply the sending of fingerprint
1633 of the client's public key (if the proof of posession of the
1634 corresponding private key is verified by the server).

1699 preserve the WHOWAS info for the client. Affected file
1700 silcd/server_util.c.
1702 * Fixed SERVER_SIGNOFF notify handling in the server. The
1703 server is now able to process incoming SERVER_SIGNOFF notify
1704 for a server that it doesn't even know about. It will remove
1705 the clients provided in the notify. Affected file
1706 silcd/packet_receive.c.
1708 * Check for partial packet in data queue after every packet that
1709 was found from the queue. Return and wait for more data if
1710 there is partial data in queue. Affected file is

1728 irssi/src/fe-common/silc/module-formats.[ch].
1730 * Wrote a help file for FILE command.
1732 * Added silc_rng_global_get_byte_fast to get not-so-secure
1733 random data as fast as possible. Random data is read from
1734 /dev/urandom if available and from the SILC RNG if not
1735 available. It is used in padding generation. Affected file
1736 lib/silccrypt/silcrng.[ch].
1738 * All packets in client library are now processed synchronously.
1739 Optimized packet processing a lot. Affected file
1740 lib/silcclient/client.c.

1751 * Assure that silc_client_notify_by_server_resolve does not
1752 resolve the client information multiple times. If it cannot
1753 be found by the first it cannot be found at all. Affected
1754 file lib/silcclient/client_notify.c.
1756 * Fixed WHOWAS command reply calling. Affected file
1757 lib/silcclient/command_reply.c.
1759 * Removed all references to silc_idlist_get_client from the
1760 Irssi SILC client since that call is internal call used by
1761 the library. The Irssi SILC client will use now client
1762 retrieval functions found in silcapi.h.
1764 * Fixed a bug in resolving nickname info before sending
1765 private message. It used freed memory. Affected file
1766 irssi/src/silc/core/silc-servers.c.
1768 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Assure my_channels statistics cannot go negative in server.
1771 Affected files silcd/server.c, silcd/server_util.c.

1787 * Added silc_net_localip to return local host's IP address.
1788 Affected file lib/silcutil/silcnet.[ch].
1790 * If key exchange or rekey protocol is active for a connection
1791 parse all packets syncronously since there might be packets
1792 in packet queue that we are not able to process without first
1793 processing packets before them. Affected file silcd/server,
1794 lib/silcclient/client.c.
1796 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1797 whether library should continue processing the packet.
1798 Affected file lib/silccore/silcpacket.h.

1844 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1845 is incomplete and is being resolved, it won't be resolved
1848 Make sure also that USERS command reply does not resolve
1849 twice information. Affected file is
1850 lib/silcclient/command_reply.c.
1852 Make sure that silc_client_get_clients_by_list does not
1853 resolve twice same information.
1855 * Check for valid client->id in the silc_server_free_client_data.
1856 Affected file silcd/server.c.
1858 * Fixed /GETKEY nick@server not to crash if the server entry
1859 is not found. Affected file lib/silcclient/command.c.
1861 * Fixed the silc_server_check_cmode_rights to check the
1862 requested modes correctly. Affected file silcd/command.c.

1867 Affected file silcd/command.c.
1869 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1871 * Call the silc_server_udpate_servers_by_server in the
1872 primary router that comes back online in the backup resuming
1873 protocol. Otherwise it routes packets wrong. Affected file
1874 silcd/server_util.[ch], silcd/server_backup.c.
1876 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1879 lib/silcutil/silcbuffmt.[ch].
1881 * Redefined the SILC packet header to include the padding
1882 length. Affected file lib/silccore/silcpacket.[ch].
1884 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1885 length for maximum padding up to 128 bytes). Affected
1886 file lib/silccore/silcpacket.h.
1888 * Removed all backwards support for old 0.5.x MAC thingies.
1889 The SILC packet header change makes it impossible to be
1890 backwards compatible.
1892 * Send the ENDING packet with timeout in the backup resuming
1893 protocol. This is to assure that all routers has connected
1894 to the primary router. Affected file silcd/server_backup.c.
1896 * Changed the RNG to take the first IV from random data. It
1897 used to take it from zero actually. Changed the RNG also
1898 to use /dev/urandom during session. /dev/random is used
1899 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1901 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Changed the SILC packet header to have the first two bytes
1904 (the packet length) encrypted. Affected files aroung the
1905 code tree, lib/silccore/silcpacket.[ch]. Removed the
1906 SilcPacketCheckDecrypt callback. It is not needed anymore
1907 since the silc_packet_receive_process will determine now
1908 whether the packet is normal or special.
1910 * Implemented the unidirectional MAC keys. Affected files
1911 lib/silcske/silcske.c, silcd/protocol.c and
1912 lib/silcclient/protocol.c.
1914 * Implemented the packet sequence number to the MAC computation.
1915 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1916 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1917 lib/silcclient/protocol.c.
1919 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1921 * Allow backup router to announce servers. All servers
1922 announced by backup router are added to the global list
1923 automatically. Update hte server's socket to our primary
1924 router also when backup router announces a server.
1925 Affected file silcd/packet_receive.c.
1927 * Do not update the client->router in the function
1928 silc_server_udpate_clients_by_server if the client is on
1929 global list. We might fail to find any specific server
1930 for locally connected clients and local cell clients. They
1931 should still use the `from' and not `to' as client->router.
1932 This fixes backup router resuming protocol. Affected file
1933 silcd/server_util.c.
1935 * Decrease channel statistics count only if the channel
1936 deletion worked. Affected files are silcd/server.c and
1937 silcd/server_util.c.
1939 * Added silc_server_update_servers_by_server to update origin
1940 of all server entries. Used during backup router protocol.
1941 Affected files silcd/server_util.[ch], silcd/server.c. and
1942 silcd/backup_router.c.
1944 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1945 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1946 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1947 lib/silccrypt/silchmac.c.
1949 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Assure that router cannot reroute the same channel message
1952 to the sender. Affected file silcd/packet_receive.c.
1954 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Made better checks that the channel message is not sent
1957 to the router it came from. Affected file is
1958 silcd/packet_send.c. Fixed memory leak too.
1960 * Announce informations for incoming router connection, but
1961 only after checking if it is replaced by backup router.
1962 Affected file silcd/packet_receive.c.
1964 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Fixed the backup resuming protocol to work in multiple
1967 router environment. Affected file silcd/server_backup.c.
1969 * Route packet only to one router in the function
1970 silc_server_packet_send_to_channel. Affected file is
1971 silcd/packet_send.c.
1973 * Fixed silc_server_send_notify_dest to set the broadcast
1974 flag. Fixed the silc_server_send_notify_topic to actually
1975 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1976 Affected file silcd/packet_send.c.
1978 * Changed the SFTP Filesystem interface. Changed the
1979 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1980 the filesystem operation function. The SilcSFTPFilesystem
1981 is now a context that is allocated by all filesystem allocation
1982 functions and it already includes the operations structure
1983 and filesystem specific context. It is given as argument
1984 now to the silc_sftp_server_start. This made the interface
1985 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1986 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1988 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Changed the backup router adding and getting interfaces
1991 in the server. The router that will be replaced by the
1992 specified backup router is now sent as argument. Affected
1993 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1996 * Added silc_net_addr2bin_ne to return the binary form of
1997 the IP address in network byte order. Affected files
1998 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2000 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Check for existing server ID in silc_server_new_server
2003 and in silc_server_connect_to_router_final and remove the
2004 old entry if it exists. Affected file silcd/packet_receive.c,
2007 * Send the channel message always to only one router, either
2008 in upstream or downstream. Affected file is
2009 silcd/packet_send.c.
2011 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2013 * Wrote the definition of the backup resuming protocol to the
2014 protocol specification.
2016 * Removed one redundant channel key generation from normal
2017 server during joining procedure. Removed one redundant
2018 channel key sending from server to router during joining
2019 procedure. Affected file silcd/command.c.
2021 * Made minor bugfixes to the backup router resuming protocol.
2022 Affected file silcd/server_backup.c, server.c.
2024 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Added --disable-asm configuration option. Affected files
2027 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2030 * Implemented the backup resuming protocol that is used to
2031 resume the primary router position in the cell after the
2032 primary router comes back online. Affected files
2033 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2034 and silcd/server_util.[ch].
2036 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Sleep two (2) seconds after sending QUIT command to server.
2039 Affected file lib/silcclient/command.c.
2041 * Assure that if outgoing data buffer is pending do not force
2042 send any data. Affected file silcd/packet_send.c.
2044 * Assure that if outgoing data buffer is pending do not force
2045 send any data. Affected file lib/silcclient/client.c.
2047 * Implemented the backup router support when the primary router
2048 goes down. The servers and routers can now use the backup
2049 router as new primary router without loosing connectivity.
2051 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2054 in the server to indicate disabled entry. All data read
2055 from the connection will be ignored and no data is sent
2056 for entry that is disabled. Affected files are
2057 silcd/idlist.h, silcd/server.c.
2059 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * Created SFTP client and server test programs in the
2062 lib/silcsftp/tests directory.
2064 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Implemented memory filesystem (virtual filesystem) for
2067 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2070 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Implemented the SFTP (SSH File Transfer Protocol) to the
2073 lib/silcsftp. It includes SFTP client and SFTP server
2076 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Moved lib/silccore/silcprotocol.[ch] to the
2079 lib/silcutil library.
2081 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2082 take variable argument list pointer as argument. Affected
2083 file lib/silcutil/silcbuffmt.[ch].
2085 * Added silc_buffer_set function that is used to set data
2086 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2087 Affected file lib/silcutil/silcbuffer.h.
2089 * Changed various routines in the core library to use the new
2090 silc_buffer_set instead of allocating new buffer only for
2093 * Added 64-bit value formatting and unformatting support to the
2094 silc_buffer_[un]format routines. Affected file is
2095 lib/silcutil/silcbuffmt.[ch].
2097 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2098 to includes/bitmove.h.
2100 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Fixed channel user mode saving in client library. Affected
2103 file lib/silcclient/command[_reply].c.
2105 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Defined the file transfer to the SILC Protocol. Added
2108 new packet type SILC_PACKET_FTP and defined File Transfer
2109 Payload. The mandatory file transfer protocol is SFTP
2110 (SSH File Transfer Protocol). Affected file in addition
2111 of the internet draft is lib/silccore/silcpacket.h.
2113 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2114 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2115 is used as part of backup router protocol when the primary
2116 router of the cell is back online and wishes to resume
2117 the position as primary router.
2119 * Redefined the MAC generation keys in the protocol. The
2120 same key is not used anymore in both direction. Both
2121 direction will now use different keys for sending and
2122 receiving. This fixes a potential security flaw. This
2123 change causes incompatibilities in the protocol.
2125 * Redefined also the MAC computation from the packet.
2126 An packet sequence number is now added to the MAC
2127 computation. This prevents possible replay attacks against
2128 the protocol. This change too causes incompatibilities
2131 Added `sequence' field to the SilcPacketContext to hold
2132 the current sequence number for the packet.
2134 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Added `created' field to the SilcIDListData in the file
2137 silcd/idlist.h to indicate the time when the entry was
2140 * Added `created' field to the SilcChannelEntry too. Affected
2141 file silcd/idlist.h.
2143 * Added `creation_time' aguments to all the announcement functions
2144 in the server. If it is provided then only the entries that
2145 was created after the provided time frame are actually
2146 announced. Affected file silcd/server.[ch].
2148 * The protocol says that the Channel ID's IP address must be
2149 based on the router's IP address. Added check for this in
2150 the silc_server_new_channel when processing incoming New Channel
2151 Payload. Affected file silcd/packet_receive.c.
2153 * Print out the correct version with --version in SILC client.
2154 Affected file irssi/src/silc/core/silc-core.c.
2156 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Fixed WHOWAS command to check for completnes of the client
2159 entry always, not just when the command is coming from client.
2160 Affected file silcd/command.c.
2162 * Added new function silc_server_packet_queue_purge to purge the
2163 outgoing data queue to the network. After the function returns
2164 it is guaranteed that the outgoing packet queue is empty.
2165 Affected file silcd/packet_send.[ch].
2167 * Purge the outgoing packet queue in the rekey protocol's final
2168 callback to assure that all rekey packets go to the network
2169 before quitting the protocol. Affected file silcd/server.c.
2171 * Added silc_client_packet_queue_parse as similar function as
2172 in server to the client library. The affected file is
2173 lib/silcclient/client.c.
2175 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * Splitted silcd/server.c and created silcd/server_util.[ch]
2178 for utility functions.
2180 * Added new socket flag SILC_SF_DISABLED to indicate that the
2181 connection is open but nothing can be sent to or received from
2182 the connection. Affected file lib/silcutil/silsockconn.[ch].
2183 The checking for disabled socket is checked in the low level
2184 silc_socket_write and silc_socket_read functions.
2186 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Allow only nicknames and channel names that fits into the
2189 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2191 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * When processing JOIN command reply in server check that if
2194 the channel exists in our global list we'll move it the local
2195 list. Affected file silcd/command_reply.c.
2197 * Fixed the check whether client is joined on the channel already
2198 in JOIN command. Affected file lib/silcclient/command.c.
2200 * Fixed the JOIN command reply to check whether the channel
2201 already exists. Affected file lib/silcclient/command_reply.c.
2203 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2205 * Added silc_ske_status_string to map the SKE error numbers
2206 to readable strings. The affected files are
2207 lib/silcske/silcske[_status].[ch].
2209 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2211 * Do not show the private channels on the WHOIS channel list
2212 as it is not allowed by the protocol. The affected file is
2215 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Assure that the packet length digged from the actual packet
2218 is something sensible in the silc_packet_decrypt_rest_special
2219 in lib/silccrypt/silcpacket.c.
2221 * Free and NULL the allocated pointer in silc_hmac_alloc if
2222 the HMAC allocation fails. The affected file is
2223 lib/silccrypt/silchmac.c.
2225 * Print the selected security properties to the log files in
2226 the server. Affected file silcd/protocol.c.
2228 * Add SKE's reference counter even if calling the completion
2229 callback manually. Otherwise it goes negative, although it
2230 does not cause any problems. The affected file is
2231 lib/silcske/silcske.c.
2233 * Remove the client entry with short timeout after giving the
2234 KILL command. Affected file lib/silcclient/command.c.
2236 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2237 case all found clients are already disconnected (WHOWAS would
2238 found them) in the server. Affected file silcd/command.c.
2240 * Update the last_receive (time of last data received) to be
2241 updated only when received private or channel message so that
2242 the idle time showed in WHOIS makes more sense.
2244 * Added boolean field `valid' in to the SilcClientEntry in the
2245 client library to indicate whether the entry is valid or not.
2246 This fixes the nickname change bug on channel when changing
2247 the nickname to be same than the old (like nick to Nick) the
2248 nickname formatter doesn't set the new nick anymore to Nick@host.
2249 Affected file lib/silcclient/idlist.[ch].
2251 * Now actually fixed the nickname changing on disconnection.
2252 Added new function silc_change_nick to the Irssi SILC Client.
2253 Affected file irssi/src/silc/core/client_ops.c,
2254 irssi/src/silc/core/silc-nicklist.[ch].
2256 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Check that the public key exists in the GETKEY command before
2259 trying to encode it. Affected file silcd/command.c.
2261 * Print some notifications on received public keys with GETKEY
2262 command in the Irssi SILC Client. Affected files are
2263 irssi/src/fe-common/silc/module-formats.[ch],
2264 irssi/src/silc/core/client_ops.c.
2266 * Use IDENTIFY command to resolve the server information in the
2267 GETKEY command instead of INFO command. Affected file
2268 lib/silcclient/command.c.
2270 * All command reply functions in the client library now calls
2271 the pending command reply callbacks even if an error has
2272 occurred. The server has done this a long time and now it was
2273 time to move the client library to this as well. Now all
2274 errors can be delivered back to the pending command reply
2275 callbacks if necessary. Affected files are
2276 lib/silcclient/command[_reply].[ch].
2278 * Change the nickname on disconnection back to the username
2279 because in reconnect the server will enforce it to it anyway.
2280 Affected file irssi/src/silc/core/silc-servers.c.
2282 * Fixed a config file parsing bug in the Irssi SILC client.
2283 Affected file irssi/src/silc/core/clientconfig.c.
2285 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * When printing the channel mode on JOIN, verify that the
2288 channel key and channel's HMAC are valid. Affected file
2289 irssi/src/silc/core/client_ops.c.
2291 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2294 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2295 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2297 * Removed channel key rekey task deleting from the function
2298 silc_server_save_channel_key. Affected file silcd/server.c.
2299 Added explicit timeout task context instead that is used to
2300 delete the task if we are registering a new task before the
2301 new task has elapsed.
2303 * When channel key rekey occurs the client library now saves
2304 the old channel key for a short period of time (10 seconds) and
2305 is able to use it in case some is still sending channel
2306 messages encrypted with the old key after the rekey. Affected
2307 file lib/silcclient/[idlist.h|client_channel.c].
2309 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Added check to the silc_server_new_id_real to not accept
2312 new ID if it is the sender's own ID. Affected file is
2313 silcd/packet_receive.c.
2315 * Assure that we do not announce ourself or the one we've
2316 sending our announcements when we're router and are announcing
2317 servers to our primary router. Affected file silcd/server.c.
2319 * Fixed silc_server_command_identify_check_client to assemble
2320 correct WHOIS packet. It send corrupted WHOIS packet and
2321 caused problem with router to router connections. Affected
2322 file silcd/command.c.
2324 Fixed also silc_server_command_whois_check the same way
2325 as for the IDENTIFY command.
2327 * Added new SilcIDListStatus to the server in the SilcIDListData
2328 structure. The status now includes the current status of
2329 the entry (like registered, resolved etc.). Affected file
2330 silcd/idlist.[ch]. Defined a bunch of different status types
2331 as well. This replaced the old boolean registered field as well.
2333 Added resolve_cmd_ident field to the SilcClientEntry structure
2334 too so that if the entry is for example being resolved so
2335 another command may attach to the same pending command reply
2336 without requiring to resolve the same entry again. This concept
2337 should optimize the WHOIS and the IDENTIFY resolving under
2338 heavy load by taking away unnecessary resolving for entries
2339 that are being resolved already.
2341 Added support for adding multiple pending commands for one
2342 command idenfier. Affected file silcd/command[_reply].[ch].
2344 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2345 before deleting the data. Otherwise the hash table will have
2346 freed data in comparison functions. Affected file is
2347 silcd/command_reply.c.
2349 * Fixed silc_idlist_replace_client_id to add the new entry to
2350 the cache with NULL nickname. Otherwise there will be invalid
2351 memory as the nickname after the nickname is freed. Affected
2352 file silcd/packet_receive.c.
2354 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2355 saved into wrong slots because the previous number of entries
2356 was not taken into account. Affected file silcd/idlist.c.
2357 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2359 * If we are router and we receive JOIN notify to a channel that
2360 does not have any users then notified client is marked as the
2361 channel founder, as it is it. The affected file is
2362 silcd/packet_receive.c
2364 * Added to the extended hash table API's table_del_*ext functions
2365 the destructor as argument too, so that the caller can decide
2366 which destructor to use or whether to use destructor at all.
2367 Affected file lib/silcutil/silchashtable.[ch].
2369 * Fixed ID Cache purging. It actually deleted the entries from
2370 the hash table after the data was freed. The hash table ended
2371 up comparing freed memory. The affected file is
2372 lib/silccore/silcidcache.c.
2374 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Fixed Irssi SILC client's KILL command's HELP syntax.
2378 * The USERS command now resolves the detailed user information
2379 if the userinfo field is missing. Affected file is
2380 lib/silcclient/command_reply.c.
2382 * Do not print error in silc_file_read if the read file does
2383 not exist. Just silently return NULL. Affected file is
2384 lib/silcutil/silcutil.c.
2386 * Fixed the silc_log_output to not wine about NULL filename
2387 and to not create some bogus " " filename. Affected file is
2388 lib/silcutil/silclog.c.
2390 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Fixed various printing bugs on the user interface in the
2393 Irssi SILC Client. Minor changes that were forgotten from
2396 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Fixed the configure.in.pre and the compilation and distribution
2399 environment to support the new autoconf 2.52. That version is
2400 now required to compile the CVS trunk.
2402 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2405 to generally parse user@fqdn format strings. Affected file
2406 lib/silcutil/silcutil.c.
2408 * Added nickname_format and nickname_force_format fields to the
2409 SilcClientParams structure. The first one defines the format
2410 for the nicknames that the library will enforce if the receives
2411 multiple same nicknames. The second one is boolean value and
2412 can be used to force the library to always enforce the format
2413 to the nicknames regardles whether there are multiple nicknames
2414 or not. This configurable formatting was employed to flexibly
2415 support accessing multiple nicknames from the user interface.
2416 The userinterface can now set the nicknames to what ever format
2417 they prefer. Affected file lib/silcclient/silcapi.h.
2419 Added function silc_client_nickname_format to the file
2420 lib/silcclient/idlist.c. It performs the nickname formatting.
2422 Added new field `hostname´ to the SilcClientEntry context.
2423 It holds the hostname of the client. Affected file is
2424 lib/silcclient/idlist.h.
2426 * Irssi SILC Client sets the nicknames in nick@hostn format.
2427 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2428 irssi/src/silc/core/silc-core.c.
2430 The WHOIS printing now also shows both the real nickname and
2431 the formatted nickname so that user knows how to access the
2432 user if there are multiple same nicknames cached. Affected
2433 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2434 printing formatting too to take the hostname now as a separate
2435 argument. The Affected file is
2436 irssi/src/fe-common/silc/modules-formats.[ch].
2438 * Changed the silc_client_get_clients_local to accept the formatted
2439 nickname as argument. It accepts the real nickname too but the
2440 formatted nickname can be used to find the true entry from
2441 multiple entries. Affected file lib/silcclient/silcapi.h and
2442 lib/silcclient/idlist.c.
2444 * Added nickname_format_parse field to the SilcClientParams.
2445 It is a callback function provided by the application to parse
2446 the nickname out of the formatted nickname string. The library
2447 calls it to get the nickname from the formatted string. Since
2448 the application generally knows better the format of the nickname
2449 string it parses it instead of the library, even though library
2450 encodes the formatted string. If the callback function is not
2451 provided then the library will use the string as is. The
2452 affected file is lib/silcclient/silcapi.h.
2454 * All the nickname strings passed to the client library in
2455 commands are now expected to be formatted nickname strings.
2456 If the command does not support the formatted nickname string
2457 it will assume that the sent string is the actual nickname.
2458 Affected file lib/silcclient/command.c.
2460 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Added public key authentication support to OPER and SILCOPER
2463 commands in the client library. Affected file is
2464 lib/silcclient/command.c.
2466 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Changed the get_auth_methdod client operation to be asynchronous.
2469 It can be async if the application resolves the authentication
2470 method from the server during the negotiation. Added new
2471 SilcGetAuthMeth completion callback that the application will
2472 call after resolving the authentication method.
2474 Added function silc_client_request_authentication_method that
2475 the application can use to resolve the authentication method
2476 from the server. Added also SilcConnectionAuthRequest callback
2477 that the library will call after the server has replied. The
2478 application can call this function if it does not know the
2479 current authentication method.
2481 Affected files are lib/silcclient/client.c and
2482 lib/silcclient/silcapi.h.
2484 * The Irssi SILC client now automatically resolves the authentication
2485 method incase any configuration information is not present (and
2486 currently there never is). The affected file is
2487 irssi/src/silc/core/client_ops.c.
2489 * Fixed public key authentication from the client library.
2490 Affected file lib/silcclient/protocol.c. Changed also the
2491 protocol specification about the public key authentication in
2492 the connection authentication protocol. The actual data to be
2493 signed is now computed with a hash function before signing.
2495 * Fixed the public key authentication from the server as well.
2496 Affected file silcd/protocol.c.
2498 * Removed the mlock()'s from the memory allocation routines.
2499 Affected file lib/silcutil/silcmemory.c. The ./configure does
2500 not check anymore for the mlock(). Affected file is
2503 * Fixed USERS command in server to allow the execution of the
2504 command for private and secret channels if the client sending
2505 the command is on the channel. Affected file silcd/command.c.
2507 * Fixed silc_client_get_clients_local to return the clients
2508 count correctly. It could return wrong value. Affected file
2509 lib/silcclient/idlist.c.
2511 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2514 types. The assembler optimizations seemed not to like 64-bit
2515 data types. The assmebler optimizations thus are now enabled
2516 also for BSD systems as opposed to only enable them for Linux.
2518 * Do not check for threads at all on BSD systems. Affected
2519 file configure.in.pre.
2521 * Removed -n and -h options from the Irssi SILC Client since
2522 they are not used in silc.
2524 * Fixed the prime generation to assure that the first digit
2525 of the generated random number is not zero since our conversion
2526 routines does not like number strings that starts with zero
2527 digit. If zero digit is seen the random number is regenerated.
2528 This caused some corrupted RSA keys when the zero first digit
2529 was met. Affected file lib/silcmath/silcprimegen.c.
2531 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Fixed WIN32 configuration in the ./configure script.
2534 Fixed to include xti.h on environments that has it.
2535 Patches by Carsten Ilchmann and andrew.
2537 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Changed the silc_id_create_client_id to be collision
2540 resistant. It is now assured that there cannot be created
2541 two same client ID's. I suspect that some weird bugs in
2542 the server were actually caused by duplicate Client IDs.
2543 Affected file silcd/serverid.[ch]. A router receiving
2544 new ID now also assures and informs the sending server
2545 if the ID caused collision.
2547 * Changed the silc_id_create_channel_id to also assure that
2548 there are no collisions.
2550 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Statement about ignoring the Mutual Authentication flag when
2553 performing rekey with PFS was a bit misleading. It is ignored
2554 if it was set in the initial negotiation, it cannot be even
2555 set in the rekey. Fixed in the ke-auth draft. Started the
2556 new versions of the protocol drafts in the doc/.
2558 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2560 * Fixed a bug in silc_client_command_identify_save when saving
2561 new channel information. The channel name was no duplicated
2562 and caused crash on exit. Affected file is
2563 lib/silcclient/command_reply.c.
2565 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Fixed the getkey command handling in the server. Send just
2568 empty OK reply to the sender if the key could not be fetched
2569 (but everything else was ok, like the key just was not available).
2570 Changed the public key parameter to optional in the protocol
2571 specs so that empty OK reply can be sent. Affected file
2574 Added a message to Irssi SILC client to tell to user if the
2575 server did not return a public key.
2577 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Fixed a channel key regeneration bug. It registered new
2580 timeout tasks exponentially until all system resources were
2581 used. Affected file silcd/server.c.
2583 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Added the SILC Document generator to the scripts/silcdoc.
2586 It can be used to generate the Toolkit Reference Manual out
2587 of the source tree. Internally it will also use the RoboDoc
2588 generator now imported in util/robodoc.
2590 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Added couple of return's in rekey protocol if error orccurred
2593 during the protocol. The execution must be terminated.
2594 Affected file silcd/protocol.c. Also, terminate the protocol
2595 always with timeout.
2597 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * The client's Client ID was created initally from the wrong
2600 nickname (it could have been in format nick@host) in the
2601 silc_server_new_client. Affected file silcd/packet_receive.c
2603 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Added some SILC_LOG_ERROR's to various error conditions
2606 if client could not be added to ID cache. Affected files
2607 silcd/packet_receive.c and silcd/server.c.
2609 * When client's sock->user_data is freed, NULL also the
2610 client->router and client->connection pointers. Added check
2611 for these pointers being NULL to various places around the
2612 code. Affected file silcd/server.c.
2614 * Added client->data.registered == TRUE checks to various
2615 places around the code to assure that unregistered client's
2616 are not handled when it is not allowed. Affected file
2619 * Added `bool registered' fields to all
2620 silc_idlist_[server|client]_get_* routines to indicate whether
2621 the fetched client needs to be registered or not. Affected
2622 file silcd/idlist.[ch].
2624 * Add your own entry as registered to the ID cache in the
2625 server. Affected file server.c.
2627 * Fixed a bug in silc_server_new_server. The SilcServer was
2628 set as the new server's context instead of SilcServerEntry.
2629 This naturally caused some weird bugs.
2631 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Do not delete the channel rekey task when adding it
2634 for in silc_server_create_channel_key.
2636 * Changed the silc_server_create_channel_key to return
2637 TRUE or FALSE to indicate the success of the channel key
2640 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Fixed MSVC++ project files and added missing files to
2643 Makefiles under win32/.
2645 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Do not add TCP_NODELAY flag if the operating system
2648 does not have it defined. Affected files are
2649 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2651 * Fixed buffer overflow from Irssi SILC Client. Affected
2652 file irssi/src/fe-common/core/themes.c.
2654 * Fixed double free in client library in the file
2655 lib/silcclient/client.c when disconnecting from server.
2657 * Applied double free patch from cras to Irssi SILC client.
2658 Affected files irssi/src/core/[modules/expandos].c
2660 * Fixed the disconnection handling to Irssi SILC Client.
2661 The application must call silc_client_close_connection
2662 in ops->connect client operation in case of failure of
2663 the connection. Affected file is
2664 irssi/src/silc/core/client_ops.c.
2666 * Do not set sock->protocol to NULL in the function
2667 silc_client_close_connection after executing the protocol's
2668 final callback since the sock might not be valid anymore.
2669 Affected file lib/silcclient/client.c.
2671 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Do not enable SILC_THREADS if the linking with libpthread
2674 did not happen. Affected file configure.in.pre.
2676 * Added notion to protocol specification that server must
2677 verify the sent authentication payload with CMODE when
2678 setting the channel founder key. Implemented it to the
2679 server. Affected file silcd/command.c.
2681 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Added _EXTRA_DIST SILC distribution variable to the
2684 distributions file. It is used to conditionally add extra
2685 files or directories to the specific distribution. Affected
2686 files ./prepare, Makefile.am.pre and distributions.
2688 Removed the `_' from the start of the distribution names.
2691 * Added README.WIN32 for instructions to compile the Toolkit
2694 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Fixed a double free in disconnection in the server. Affected
2697 file is silcd/server.c.
2699 * Fixed the lib/silcske/groups.c to work now also with GMP
2700 MP library. The string conversion did not work when using
2701 specific base and the base is indicated in the string as well.
2703 * Created win32/ directory which now includes MSVC++ specific
2704 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2705 It will appear only in the toolkit distribution
2707 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Changed the key material distribution function in case when
2710 the hash output is too short. The data is now concatenated
2711 a bit differently than it used to. Made the change to the
2712 SKE protocol specification.
2714 * Added better GMP detection to configure.in.pre. A patch
2717 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2719 * Fixed a minor bug in SKE that might cause some problem on
2720 some platforms. Affected file lib/silcske/silcske.c.
2722 * Added the cookie checking for initiator in the SKE. It checks
2723 that the responder returns the sent cookie unmodified. The
2724 affected file is lib/silcske/silcske.c. Added new SKE
2725 error type INVALID_COOKIE that can be sent during the
2726 negotiation. Fixed some memory leaks as well.
2728 * Added the "invalid cookie" error message to Irssi SILC client's
2731 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Added `task_max' field to the SilcClientParams to indicate
2734 the maximum tasks the scheduler can handle. If set to zero,
2735 default values are used. Affected file lib/silcclient/silcapi.h.
2737 * Fixed memory leaks in silc_client_close_connection. Affected
2738 file lib/silcclient/client.c.
2740 * Added silc_client_del_client_entry to client library to free
2741 all memory of given client entry. Affected file is
2742 lib/silcclient/idlist.[ch].
2744 * Added new functions silc_client_del_channel and
2745 silc_client_del_server to delete channel and server entries.
2746 Affected file lib/silcclient/[silcapi.h/idlist.c].
2748 * Removed silc_client_del_client_by_id from silcapi.h.
2750 * Fixed the INFO command to return the server's own info
2751 correctly when querying by Server ID. Affected file is
2754 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Removed the non-blocking settings in WIN32 code in the
2757 silc_sock_[read/write] and added SleepEx instead. Affected
2758 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2759 of input data is now checked with FIONREAD and ioctlsocket.
2761 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Call silc_schedule_task_del_by_context in the
2764 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2765 Affected file lib/silccore/silcprotocol.c.
2767 * Call silc_protocol_cancel for active protocols in the
2768 silc_server_close_connection if the funtion
2769 silc_server_free_sock_user_data has not been called.
2770 Affected file silcd/server.c.
2772 * Generic tasks cannot be deleted using the del_by_fd
2773 task deleting function since generic tasks does not match
2774 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2776 * Added a notion to SILCOPER help file that the SILCOPER works
2777 only on router server, not on normal server.
2779 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Added for WIN32 support for the new scheduler as well.
2782 Affected file lib/silcutil/win32/silcwin32schedule.c.
2784 * Fixed the SHA1 implementation to work on various platforms.
2786 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2789 API. It is part of the scheduler now. Everything else is
2790 as previously but some functions has changed their names.
2791 Checkout the lib/silcutil/silcschedule.h for the interface.
2792 Updated all applications to use the new interface. Affected
2793 files are lib/silcutil/silcschedule.[ch].
2795 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Found a bug in the SKE implementation. The HASH value,
2798 specified by the protocol, was not computed correctly. The
2799 public key of the responder was not added to the computation
2800 even though it is mandatory. Affected file lib/silcske/silcske.c.
2801 This unfortunately causes incompatibilities with older
2802 clients and servers.
2804 * Added WIN32 specific network init and uninit functions:
2805 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2806 the Winsock2. Affected file lib/silcutil/silcnet.h and
2807 lib/silcutil/win32/silcwin32net.c.
2809 * Set the socket always to nonblocking mode on WIN32 after
2810 reading data or writing data. Affected file is
2811 lib/silcutil/win32/silcwin32sockconn.c.
2813 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Fixed various compilation problems under WIN32. Affected
2816 files lib/silcutil/win32/silcwin32thread.c and
2817 lib/silcutil/win32/silcwin32schedule.c.
2819 * Removed all _internal.h #includes from public header
2820 files. Internal headers must never be included from
2823 Removed also the lib/silcske/payload_internal.h file.
2825 * All include files that may be needed (public and some others
2826 included by the public headers) by application developers are
2827 now copied to the ./includes directory. It does not copy any
2828 internal headers. Affected file Makefile.defines.pre and all
2829 Makefile.am's under lib/ and subdirs.
2831 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Do not change the ~/.silc directory's permissions automatically.
2834 Affected file irssi/src/silc/core/clientutil.c.
2836 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2838 * Do not cancel the protocol in silc_server_close_connection
2839 it might cause recursion. Now cancelled in the function
2840 silc_server_free_sock_user_data. Affected file silcd/server.c.
2842 * Fixed the silc_server_remove_clients_by_server to regenerate
2843 the channel keys correctly finally. Added also new function
2844 silc_server_remove_clients_channels to actually do it.
2845 Affected file silcd/server.c.
2847 * Fixed the silc_server_new_channel to not crash by giving
2848 wrong router to the new channel. Affected file is
2849 silcd/packet_receive.c.
2851 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2854 which is given as argument to the silc_client_alloc now.
2855 It can be used to configure the client and set various parameters
2856 that affect the function of the client.
2858 * The USERS command in server did not check whether the channel
2859 is private or secret. Affected file silcd/command.c.
2861 * Added new argument to the USERS command in protocol specification.
2862 The USERS command now can take the channel name as argument
2863 as well. Added support for this in client and server and
2864 updated the protocol specs.
2866 * Completed the GETKEY command in client. It can be now used
2867 to fetch also servers public key not only some clients.
2868 Affected files lib/silcclient/command[_reply].c.
2870 * Added silc_client_get_server to return server entry by the
2871 server name. Affected files lib/silcclient/silcapi.h and
2874 * Redefined the IDENTIFY command in protocol specification to be
2875 more generic. It now can be used to query information about
2876 any entity in the SILC Network, including clients, servers and
2877 channels. The query may be based either the entity's name
2878 or the ID. Added support for this in both client and server.
2880 Affected files silcd/command.c and lib/silcclient/command.c
2881 and command_reply.c.
2883 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2884 the _from_client and _from_server functions. Affected file
2887 * Added silc_client_get_channel_by_id_resolve to the file
2888 lib/silcclient/silcapi.h to resolve channel information by
2889 its ID. Added also silc_client_get_channel_by_id that
2890 does not resolve it from the server.
2892 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * Added SilcServerEntry context into the client library
2895 to represent one server. The INFO command now allocates
2896 these to save the resolved server info. For now on the
2897 client library will also keep information about servers,
2898 connected and resolved with INFO.
2900 The INFO command now allocates the SilcServerEntry context
2901 and saves the server info there. The COMMAND_REPLY in
2902 the INFO now returns the parameters to application in
2903 same order as defined in the protocol specification.
2905 The entries are cached in the client->server_cache.
2907 * The INFO command is now issued after received the Client ID
2908 from the server. Affected file lib/silcclient/client.c.
2910 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2911 to the application as the mode changer might be server.
2912 It is guaranteed that NULL is not returned anymore to the
2913 application. Affected file lib/silcclient/client_notify.c.
2915 The ID Type is now also passed to the application so that
2916 it can check whether the returned entry is SilcClientEntry
2919 Added new function silc_client_get_server_by_id to return
2920 the server entry by ID. Affected files are the
2921 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2923 * Do not create the channel in the Irssi SILC Client when issuing
2924 the JOIN command but when received the sucessful JOIN command
2925 reply. Otherwise the channel might get created even though we
2926 could not join it. The Affected file is
2927 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2929 * Fixed a channel joining bug in router. The router must also
2930 check the channel modes, invite and ban lists etc. when serving
2931 the JOIN command sent by normal server. Affected file is
2932 silcd/command.c. The router now resolves the client's
2933 information from the server who sent the JOIN command if it
2934 does not know it, and processes the JOIN command only after
2937 * Changed the SilcCommandCb to take new argument; void *context2.
2938 Affected file lib/silccore/silccommand.h
2940 The second argument in the command callbacks in the server now
2941 includes the SilcServerCommandReplyContext if the command was
2942 called as pending command callback from the command reply.
2943 Otherwise it is NULL. When called as pending the status of the
2944 command reply will be checked and if it was erronous the
2945 error will be sent to the original sender of the command.
2946 This way the client always receives the error messages even
2947 though the server was actually the one who received the error
2948 when it resent the command to router, for example. Affected
2949 files silcd/command[_reply].[ch].
2951 * Fixed sending WHOWAS command's error message to client if
2952 the requested client could not be found. It was missing.
2955 * Changed the CMODE and CUMODE commands reply arguments in the
2956 protocol specification. The Channel ID is now sent in both
2957 of the commands to identify the channel. Implemented this
2958 new feature to the client and server. Affected files
2959 lib/silcclient/command_reply.c and silcd/command.c.
2961 * Made better checks for invite and ban lists in the JOIN
2962 command in server. Affected file silcd/command.c.
2964 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * The server now performs the incoming host IP/DNS lookup
2967 using the silc_socket_host_lookup and thus does not block
2968 the server anymore. Affected file silcd/server.c.
2970 * Completed the multi-thread support for SILC Scheduler in
2971 the lib/silcutil/silcschedule.c.
2973 * Fixed the configure.in.pre to detect the pthread correctly
2976 * Fixed a deadlock in silc_task_queue_wakeup in the file
2977 lib/silcutil/silctask.c.
2979 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Added new function silc_schedule_wakeup that is used in
2982 multi-threaded environment to wakeup the main thread's
2983 schduler. It needs to be used when a thread adds a new task
2984 or removes a task from task queues. After waking up, the
2985 scheduler will detect the task queue changes. If threads
2986 support is not compiled in this function has no effect.
2987 Implemented the wakeup mechanism to both Unix and WIN32
2988 systems. Affected files are lib/silcutil/silcschedule.[ch],
2989 lib/silcutil/unix/silcunixschedule.c and the
2990 lib/silcutil/win32/silcwin32schedule.c.
2992 * Added new function silc_task_queue_wakeup to wakeup the
2993 scheduler by the specified task queue. Affected file
2994 lib/silcutil/silctask.[ch].
2996 * The silc_socket_host_lookup_start now wakes up the scheduler
2997 after adding the timeout task. Affected file is
2998 lib/silcutil/silcsockconn.c.
3000 * The silc_socket_host_lookup is synchronous now if the threads
3001 support is not compiled in. However, the callback is still
3002 called asyncronously through the scheduler, anyway. Affected
3003 file lib/silcutil/silcsockconn.c.
3005 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Added new function silc_socket_host_lookup to perform
3008 asynchronous IP and FQDN lookups for the socket connection.
3009 Affected files lib/silcutil/silcsockconn.[ch].
3011 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3014 that may or may not compile the mutex support in.
3016 Changed the silc_mutex_alloc interface. It allocates the
3017 mutex now to the sent pointer and returns TRUE or FALSE.
3019 Affected file lib/silcutil/silcmutex.h.
3021 * Wrote the SILC Task Queue interface to support multi-threads.
3022 Affected file lib/silcutil/silctask.[ch].
3024 * Wrote the SILC Scheduler to support multi-threads. Affected
3025 file lib/silcutil/silcschedule.c.
3027 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3030 in lib/silcutil/win32/.
3032 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Defined SILC Mutex API and SILC Thread API and implemented
3035 them for Unix. Affected files are
3036 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3037 lib/silcutil/unix/silcunixmutex.c and
3038 lib/silcutil/unix/silcunixthread.c.
3040 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Fixed the silc_server_remove_clients_by_server's channel
3043 key re-generation. The hash table handling was incorrect
3044 and would not work with many channels. Affected file is
3047 * Fixed some memory leaks around the server code.
3049 * Rewrote the silc_server_get_users_on_channel to support IPv6
3050 based Client ID's. Affected file silcd/server.c.
3052 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3053 specification. However, a separate document must be written
3054 to define the detailed signing procedure and the payload
3055 associated with the flag. Defined the flag to the
3056 lib/silccore/silcchannel.h as well.
3058 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Changed the dynamic tables to static size tables in the
3061 lib/silccrypt/silchmac.c.
3063 * Removed GCC dependencies from the code. A patch by cras.
3065 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Do not show the error "Error receiving packet bla bla"
3068 in server if it really was not an error (-2 means that reading
3069 is pending). Affected file silcd/server.c.
3071 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Fixed a possible crash in silc_server_remove_clients_by_server
3074 in silcd/server.c. Fixed there also some memory leaks.
3076 * Fixed the silc_idlist_replace_client_id. It could replace
3077 wrong key in the hash table. Affected file silcd/idlist.c.
3079 * Do not check whether there are global users on the channel
3080 if the channel->global_users is FALSE. Affected functions
3081 silc_server_remove_from_one_channel and
3082 silc_server_remove_from_channels in silcd/server.c. Also,
3083 do not check if the removed client is local as we can be
3084 sure that global client was not removed from the channel
3085 and checking for global users is not needed.
3087 * The silc_server_remove_clients_by_server now re-generates
3088 the channel keys correctly for those channels that had
3089 clients removed from them. Affected file silcd/server.c.
3091 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Found the reason of random crashes in the server. We weren't
3094 ignoring the SIGPIPE signal (which can be sent in write())
3095 and it crashed the server. Affected file silcd/silcd.c.
3097 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3099 * Assure that sock->user_data is not NULL in the function
3100 silc_server_packet_send in silcd/packet_send.c.
3102 * Disconnect the remote connection if it could not be added
3103 to any ID lists in the server. The affected file is
3106 * Check in silc_server_packet_send[_real/dest] that the
3107 socket is not disconnecting and ignore the data if it is.
3108 Affected file silcd/packet_send.c.
3110 * Define inline to __inline on native WIN32 compilation.
3111 Affected file includes/silcwin32.h.
3113 * Added some explicit type casts for inline code since MSVC
3114 require them. Affected files lib/silcutil/silcbuffer.h,
3115 lib/trq/silcdlist.h and lib/trq/silclist.h.
3117 * Print warning in log files from now on if the packet
3118 decryption fails. Affected file silcd/server.c.
3120 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Changed the `say' client operation's interface to accept
3123 new `type' argument to indicate the type of the message sent
3124 by the library. The application may filter the library's
3125 messages according the type. The affected file is the
3126 lib/silcclient/silcapi.h.
3128 * Added two new functions to lib/silcclient/silcapi.h:
3129 silc_client_del_client and silc_client_del_client_by_id.
3130 Affected file lib/silcclient/idlist.c.
3132 * Moved the clientincludes.h from includes/ to silc/ and
3133 serverincludes.h from includes/ to silcd/.
3135 * The modes for the CMODE and CUMODE are now passed as
3136 uint32 for application with COMMAND_REPLY. The affected
3137 file is lib/silcclient/command_reply.c.
3139 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * /WHOIS without arguments shows client's own information.
3142 Affected file lib/silcclient/command.c.
3144 * Changed PING to not accept any arguments. The specs
3145 says that client can ping only the connected server so
3146 requiring an argument is not needed. Affected file is
3147 lib/silcclient/command.c.
3149 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Fixed a fatal bug in private message sending and reception
3152 encryption and decryption when using private message keys.
3153 The implementation was incorrect and did not follow the
3154 specification. It causd that some of the message were
3155 lost since it did not use the sending and receiving keys
3156 as the protocol suggests. This has been fixed and will cause
3157 incompatibilities with older clients when sending private
3158 message encrypted with private message keys. Affected files
3159 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3160 and various other in Irssi SILC Client.
3162 Added `responder' boolean argument to the functions
3163 silc_client_add_private_message_key[_ske] to indicate when
3164 the key is added as responder or initiator of the key
3167 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3169 * Removed the silc_ske_check_version function and created
3170 a SilcSKECheckVersion callback. Added also a function
3171 silc_ske_set_callbacks that is now used to set all SKE
3172 callbacks. The callback functions are not given to
3173 the SKE functions anymore, but this function is used to
3176 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3178 * Added `silc_version' argument to the silc_client_alloc
3179 to define the version of the application for the library.
3180 The library will use the version string to compare it
3181 against the remote host's (usually a server) version
3182 string. Affected file lib/silcclient/silcapi.h
3184 * Added the KE protocol context to Key Agreement context
3185 in client library so that we can abort the SKE if it
3186 is in process when we get timeout. Affected file is
3187 lib/silcclient/client_keyagr.c.
3189 * Do not resolve the client ID forever if it returns in the
3190 first time that such client does not exist. This was done
3191 for example with private message. Affected file is
3192 lib/silcclient/client_prvmsg.c.
3194 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3196 * Do not add regex.h for WIN32. The affected file
3197 includes/silcincludes.h.
3199 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3200 not work yet 100%. It generates the DLL's automatically
3201 when compiling with --with-win32 under cygwin.
3203 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * lib/contrib/regex.c is not compiled on WIN32.
3207 * Added silc_net_get_socket_opt function to the
3208 lib/silcutil/silcnet.h.
3210 * Added includes/silcwin32.h for WIN32 specific includes
3213 * Do not use ptime structure or any of the posix process
3214 functions on WIN32 in lib/silccrypt/silrng.c.
3216 * Added silc_gettimeofday to provide generic function
3217 for struct timeval on all platforms. Added the function
3218 to lib/silcutil/silcutil.h.
3220 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3222 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3223 library as they clearly belong there. As a plus side we
3224 can make the actual socket connection routines platform
3227 Added also new generic function silc_socket_read and
3228 silc_socket_write (that used to be silc_packet_[read/write].
3229 The implementation of these are platform specific.
3231 * Added WIN32 specific routines of silc_socket_[read/write]
3232 to lib/silcutil/win32/silcwin32sockconn.c.
3234 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Added preliminary support for native WIN32 compilation under
3237 cygwin (using the -mno-cygwin option for GCC) to the
3238 ./configure.in.pre. The --with-win32 now prepares the
3239 compilation for native WIN32.
3241 * Rewrote the SILC Scheduler interface in the file
3242 lib/silcutil/silcschedule.h. The scheduler is now context
3243 based and does not have anymore any global static scheduler.
3244 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3245 and created lib/silcutil/win32 directory for WIN32 based
3248 * Added Unix specific network routines to the
3249 lib/silcutil/unix/silcunixnet.c and the old
3250 lib/silcutil/silcnet.c includes now only generic routines.
3252 Added WIN32 specific network routines to the
3253 lib/silcutil/win32/silcwin32net.c.
3255 * Added Unix specific utility functions from the
3256 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3258 * Added WIN32 SILC Scheduler to the file
3259 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3262 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Do not handle JOIN notify in the server if the target client
3265 is not registered (idata->registered == FALSE). The affected
3266 file is silcd/packet_receive.c.
3268 * Update the nickrec->founder in event_cumode in the Irssi SILC
3269 client. Affected file irssi/src/silc/core/silc-channels.c.
3271 * Fixed the CUMODE_CHANGE notify handling in the server when
3272 server and router are announcing their clients on channels.
3273 Now the mode changes are saved and notified correctly. The
3274 affected file is /silcd/packet_receive.c.
3276 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3277 They really did not replace the cache entry in the ID Cache.
3278 Now they do that. Affected file silcd/idlist.c.
3280 * Fixed the KICK notify handling in the Irssi SILC client to
3281 update the channel records so that the kicked client does not
3282 appear to be on the channel. The affected file is
3283 irssi/src/silc/core/silc-channels.c.
3285 * Always update the conn->current_channel when executing command
3286 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3288 * Fixed the KILL notify handling in Irssi SILC client to remove
3289 the killed client on all channels.
3291 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3293 * Fixed the silc_parse_command_line to remove extra spaces
3294 from the start and end of the arguments. Affected file is
3295 lib/silcutil/silcutil.c.
3297 * Cancel and free any active protocol in the function
3298 silc_server_close_connection. Affected file silcd/server.c.
3300 * Cancel and free any active protocol in the function
3301 silc_client_close_connction. Affected file is
3302 lib/silcclient/client.c.
3304 * Do not execute the KILL command for clients that are in
3305 history (ie. they are not in the network). Affected file is
3308 * Fixed KILL notify handling, client does not crash anymore.
3309 Affected file irssi/src/silc/core/silc-channels.c.
3311 * Reduced the default packet buffer size from 2048 to 1024 in
3312 lib/silccore/silcpacket.c.
3314 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3315 counter to the SKE context that is incresed when the SKE library
3316 performs async operation outside the library. If the outside
3317 process frees the SKE context and FREED status will be set
3318 and the library will detect after the sync operation that the
3319 libary is freed. The affected files are
3320 lib/silcske/silcske[_status].[ch].
3322 * Resolve the client entry information in the function
3323 silc_client_channel_message to assure that NULL pointer is not
3324 passed as client entry to the application. */
3326 * Fixed the task timeout calculation to assure that there is
3327 never negative timeouts. The affected file is
3328 lib/silcutil/silcschedule.c.
3330 * Fixed the channel user mode notification sending in server.
3331 It was sent point-to-point to the router (or to server by router)
3332 but it needs to be destined to a channel. The routines now
3333 supports sending the channel user mode notifys to the channels
3334 when announcing clients and channels. Affected files are
3335 silcd/server.c and silcd/packet_receive.c.
3337 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3338 It did not actually replace the old channel entry in the cache.
3339 Affected file lib/silcclient/client_notify.c.
3341 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Fixed a possible crash in silc_packet_send_prepare. It now
3344 assures always that there is enough space in the buffer and
3345 at the tail area of the buffer (for MAC).
3347 Fixed the inbound buffer reallocation in silc_packet_read.
3348 It was old code and did not handle the reallocation correctly.
3351 The affected file is lib/silccore/silcpacket.c.
3353 * Fixed buffer overflow in silc_parse_nickname in the file
3354 lib/silcutil/silcutil.c.
3356 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * make install generates new server keys only if there is not
3361 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3364 Added check that if the NOREPLY is set then we will not send
3365 the away message. This avoids infinite loop of away messages
3366 if both clients are away. The affected file is
3367 lib/silcclient/client_prvmsg.c.
3369 * Fixed client crash if /NICK was given without arguments.
3370 Affected file lib/silcclient/command.c.
3372 * Server does not send the invite list in INVITE command back
3373 to the client if the list was not altered. Added this notion
3374 to the protocol spec as well. Affected file silcd/command.c.
3376 Fixed possible crash in INVITE command by checking the
3377 value of silc_server_get_client_route command.
3379 * Fixed the INVITE notify type handling. The arguments are now
3380 taken in correct order and client does not crash. The affected
3381 file is irssi/src/silc/core/silc-channels.c.
3383 Removed the "Inviting xxx to channel" message from the
3384 client library away and let the application handle it.
3385 Affected file lib/silcclient/command.c. Added that message
3386 to Irssi SILC client's message formats.
3388 * Fixed CMODE command crash in client. It now checks the
3389 amount of arguments correctly and does not crash. The affected
3390 file is lib/silcclient/command.c.
3392 * Do not create new channel automatically in silc_channels_join
3393 but check whether the channel by that name already exists.
3394 Affected file irssi/silc/core/silc-channels.c.
3396 * Do not send the SERVER_SIGNOFF to router if the disconnected
3397 entity was the router. Affected file silcd/server.c.
3399 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3400 SILC client as it was missing from there.
3402 Added the handling of the KICK notify to the Irssi SILC client
3403 as it was missing. Added "you have been kicked" message to
3404 Irssi SILC client's message modules formats.
3406 Added the handing of the KILL notify to the Irssi SILC client
3407 as it was missing. Added the kill message module formats
3410 The affected file is irssi/src/silc/core/silc-channels.c.
3412 * The router did not save the channel mode the server announced.
3413 Affected file silcd/packet_receive.c.
3415 * Fixed a possible crash in INFO command in server. If the
3416 server did not provide the server info it crashed. Affected
3417 file silcd/command.c.
3419 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Fixed the GETKEY command in the server to check also the
3422 global list. Otherwise the GETKEY would not work correctly
3423 in normal SILC server. Affected file silcd/command.c.
3425 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Fixed GETKEY crash, it crashed if the command did not succseed.
3429 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3432 is now real and not just an macro interface to GMP.
3434 Removed the entire GMP from the source tree and imported new
3435 NSS MPI library instead. Reason for removing GMP is that it is
3436 extremely large and compiles extremely slow. The NSS MPI
3437 is only a few files and compiles in less than 10 seconds.
3438 The speed is also about the same as GMP. The MPI is imported
3439 to lib/silcmath/mpi.
3441 If the system has GMP installed we will still use the GMP.
3442 If it is not then the NSS MPI will be compiled.
3444 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Merged a long nickname (127 characters long) crash bugfix from
3447 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3449 * Merged a freed memory reference bugfix from Irssi CVS tree.
3450 Affected file irssi/src/core/commands.c.
3452 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Added the server's public key sving and verification to the
3455 server when performing the SKE. This was missing and the
3456 remote server's (or router's) public key was accepted without
3457 checking whether we have it previously or trust it at all.
3458 Affected file silcd/protocol.c.
3460 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Check in the silc_server_timeout_remote if protocol is active
3463 and make sure that the protocol's final callback is called so
3464 that all memory if freed. Affected file silcd/server.c.
3466 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * silc_server_whois_send_reply crashed the server if the nickname
3469 was 127 characters long. Affected file silcd/command.c.
3471 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Added sanity check to the silc_server_new_client. If the hostname
3474 is provided inside username then check that the provided hostname
3475 really is the same as the resolved one. If the hostname was not
3476 resolved then check it from the public key. Affected file is
3477 silcd/packet_receive.c.
3479 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3480 if the server disconnected us and the connection is not valid
3481 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3483 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3484 the library to the lib/silcutil/silcutil.[ch].
3486 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Close log file after open. Affected file
3489 lib/silcutil/silclog.c.
3491 * Check whether sock == NULL in silc_client_send_packet and return
3492 if it is. Affected file lib/silcclient/silcclient.c.
3494 * Check rec->entry == NULL in the Irssi SILC Client before
3495 sending the channel message. Affecte file is
3496 irssi/src/silc/core/silc-servers.c.
3498 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Merged a splitted window bugfix from Irssi CVS tree. The
3501 affected file is irssi/src/fe-text/textbuffer-view.c.
3503 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3504 It did not print nickname.
3506 * Improved the distributions system a bit.
3508 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3511 irssi/src/fe-text/gui-window.c.
3513 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3514 to in-active server. The affected file is
3515 irssi/src/silc/core/client_ops.c.
3517 * Resolve the client in USERS command reply if the entry does
3518 not have username resolved. The affected file is
3519 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3520 command to WHOIS command to really resolve stuff. The USERS
3521 is not used any more in any critical section so WHOIS can
3522 be used even though it might be slower than IDENTIFY.
3524 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3527 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Changed the protocol API a bit more consistent in the
3530 lib/silccore/silcprotocol.[ch].
3532 * Changed the following headers to ROBODoc format:
3534 lib/silccore/silcpayload.h
3535 lib/silccore/silcprotocol.h
3536 lib/silccore/silcsockconn.h
3538 All core library headers are now formatted.
3540 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Fixed a bug in Irssi SILC client; do not show that you are
3543 server/router operator if you really are not. Affected file is
3544 irssi/src/silc/core/client_ops.c.
3546 * Renamed silc_command_free_payload to silc_command_payload_free.
3547 Affected file lib/silccore/silccommand.h
3549 * Added silcmath.h to include the prototoypes of various routines
3550 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3553 * Changed the following headers to ROBODoc format:
3555 lib/silccore/silcchannel.h
3556 lib/silccore/silccommand.h
3557 lib/silccore/silcid.h
3558 lib/silccore/silcidcache.h
3559 lib/silccore/silcmode.h
3560 lib/silccore/silcnotify.h
3561 lib/silccore/silcpacket.h
3562 lib/silcmath/silcmath.h
3564 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Added checking to the server code not to start the server if
3567 ciphers and stuff are not configured properly. Affected files
3568 silcd/serverconfig.[h] and silcd/server.c.
3570 * Changed the layout of the header files of the public interfaces
3571 in the SILC libraries. The new layout supports ROBODoc
3572 documentation tool (and some others) so that it is easy to create
3573 a library reference manual. All the other headers and source
3574 code must still follow the CodingStyle document. Also source
3575 code must not include these ROBODoc stuffs, only the headers.
3576 Furthermore, all public interface headers must now be named
3577 by using `silc' prefix, example: silcapi.h, silccipher.h.
3578 Some files were renamed due to this. All the other headers
3579 must not be used as public interfaces. I will update the
3580 CodingStyle document later. Changed following headers, so far:
3582 lib/silcclient/silcapi.h
3583 lib/silccore/silcauth.h
3584 lib/silccore/silcprivate.h
3585 lib/silccrypt/silcdh.h
3587 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Removed silc_client_packet_send_flush from the client library
3592 as it is not needed. Affected file lib/silcclient/client.[ch].
3594 * Added printing of message of unresolved authentication method
3595 to the Irssi SILC client. Added it to the module formats.
3596 Removed the same message from the client library.
3598 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Added new distribution feature, DISTLABEL. Every distribution
3601 can define own preprocessor label that can be used in the
3602 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3603 file distributions, acconfig.h.pre and prepare.
3605 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added Makefile.defines_int to include the actual definitions
3608 for Makefile.defines.in. Tested the new distribution system,
3609 created distributions and tested installation.
3611 * Added AWAY message printing to the Irssi SILC client. Added
3612 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3614 * Added SCONNECT command to call the SILC's CONNECT command.
3615 Cannot use CONNECT directly since Irssi uses that internally.
3616 Affected file irssi/src/silc/core/silc-servers.c.
3618 Added ACTION local command. It is same as ME command but takes
3619 the channel as mandatory argument.
3621 Rewrote some of the Irssi's help files to suite for SILC
3624 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Added Makefile.defines[.in] that should for now on be included
3627 in all Makefile.am file in the source tree. That file includes
3628 all common compilation definitions for SILC source tree.
3630 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Minor changes to the ./prepare script to change the package
3633 name according the distribution name to the configure.in.
3635 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Created new distribution system. Added file `distributions'
3638 that defines all the distributions that can be created out of
3639 the SILC source tree. The ./prepare script now reads that
3640 file to determine how to prepare the distributions. The
3641 first argument to the ./prepare is the name of the distribution
3642 and second is the version of the distribution. If given
3643 without arguments it creates the default (toolkit) distribution
3644 with the default version (defined in ./prepare).
3646 All Makefile.am files that are subject to the distributions
3647 are now named as Makefile.am.pre. These are ./Makefile.am
3648 and lib/Makefile.am. Others may be changed later.
3650 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added invite list, ban list, some key management and connection
3653 error message printing to module formats in the Irssi SILC client.
3655 * Added new silc_client_set_away_message to set the away message
3656 that is back to the person who sent private message. The
3657 affected file lib/silcclient/silcapi.h and the
3658 lib/silcclient/client_prvmsg.c.
3660 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Fixed the private message sending in the Irssi SILC client,
3663 added local command KEY to the Irssi SILC client.
3665 Added key management and key agreement message formats to the
3666 irssi/src/fe-common/silc/module-formats.[ch].
3668 Added USERS (alias WHO) printing, server/router operator
3669 indication and LIST command printing to the module formats.
3671 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Fixed channel joining notify handling, cumode notify handling
3674 from Irssi SILC client.
3676 * Added SILC specific module-formats to the Irssi SILC client so
3677 that SILC specific message hilighting, colors etc is possible.
3678 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3680 Added channel mode, channel user mode, actions, notices,
3681 whois and whowas printing to the the module-formats.c.
3683 * Fixed a bug in channel deletion in the server. The channel
3684 is not left to the cache even if the channel founder auth mode
3685 is set when there are no users anymore on the channel. Affected
3686 file silcd/server.c.
3688 * The silc_net_localhost now resolves the entire hostname including
3689 the domain name. Affected file lib/silcutil/silcnet.c.
3691 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Changed the ask_passphrase client operation to be ascynchronous.
3694 It has now a completion callback and a context that the
3695 application must call after it has got the passphrase from
3696 the user. Affected files lib/silcclient/silcapi.h,
3697 lib/silcclient/protocol.c, lib/silcclient/command.c and
3700 Added SilcAskPassphrase callback that the application calls
3701 to deliver the passphrase to the library.
3703 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3704 The public key verification and especially a certificate
3705 verification is asynchronous procedure.
3707 Added new SILC_SKE_STATUS_PENDING status to indicate the
3708 request is pending and a callback will be called to finalize
3711 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3712 indicate that remote end did not send its public key (or
3713 certificate), even though we require it. Added check for this
3714 condition in the SKE. This was a security bug, now fixed.
3716 Defined new SilcSKEVerifyCbCompletion callback that is called
3717 when the verification process is completed.
3719 The affected files lib/silcske/silcske_status.h and
3720 lib/silcske/silcske.[ch].
3722 * Changed the verify_public_key client operation to be async
3723 as well. Defined SilcVerifyPublicKey callback that is used to
3724 indicate the success of the public key verification process.
3726 Changed the server and client to use the new async client
3729 * Changed the Irssi SILC client's internal scheduler to be called
3730 twice as many times as it used to be. As a result the client
3731 should be a bit faster now. Affected file is
3732 irssi/src/silc/core/silc-core.c.
3734 * Added support to Irssi SILC client of asynchronous public key
3735 verification and passphrase inquiry. Affected file is
3736 irssi/src/silc/core/silc-core.c.
3738 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Do not say "You have left channel %s" in client library.
3741 Moved it to the application. Affected files are
3742 lib/silcclient/command.c and silc/client_ops.c.
3744 * Fixed silc_client_get_clients. Command context was not
3745 duplicated and was freed memory in the callback. Affected
3746 file lib/silcclient/idlist.c.
3748 * Do not say "you are now talking..." on JOIN command in the
3749 client library. The appliation must handle it.
3751 * Do not say ".. changed topic to" in command reply in the
3752 client libary. The application must handle it.
3754 * Fixed TOPIC command sending in the client library.
3756 * Fixed a memory leak in silc_client_command_free in the file
3757 lib/silcclient/command.c.
3759 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Imported a modified version of Irssi client to the source tree.
3762 The Irssi will be used to create a new client called
3763 Irssi SILC. Imported to irssi/.
3765 Added silc_core_init_finish function to the Irssi. Affected
3766 file irssi/configure.in.
3768 A lot changes in the Makefile.ams around the irssi tree.
3770 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3772 * Do not rehash if the new size is same as the old size of the
3773 hash table, in the silc_hash_table_rehash*. The affected file
3774 lib/silcutil/silchashtable.c.
3776 * Replaced hash_table_del_by_context calls from the server
3777 (when channel->user_list and client->channels) to the
3778 hash_table_del as it is sufficient and faster.
3780 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Added silc_hash_table_list, silc_hash_table_get and the
3783 SilcHashTableList structure to provide an alternative way to
3784 traverse the hash table. The affected files are
3785 lib/silcutil/silchashtable.[ch].
3787 * Changed the server's idlist routines to use the hash table
3788 routines to optimize the code.
3790 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Replaced the client entry's `channel' list and channel entry's
3793 `user_list' list to hash tables for optimized lookup. Changed
3794 the code to use the hash table interface around the code.
3795 Affected file lib/silcd/idlist.[ch].
3797 * Added `auto_rehash' boolean argument to the function
3798 silc_hash_table_alloc to indicate whether the hash table should
3799 auto-rehash when it thinks is appropriate time. It will
3800 increase the hash table size if the there is twice as much
3801 entries in the table than the size of the table, and will
3802 decrease the size if there are twice as less entries than
3803 the size of the table.
3805 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3809 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * silc_idcache_purge_by_context deletes the entry now by context
3812 as it is supposed to do. Affected file lib/silccore/idcache.c.
3814 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3815 client is not anymore valid (WHOWAS givens the info) and not
3816 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3818 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Removed the `data' and `data_len' arguments from the ID Cache
3821 interfaces and added `name' argument. ID Cache does not handle
3822 anymore the binary data only a names associated with given ID.
3824 * When hashing a Client ID with silc_hash_id the entire ID is
3825 not hashed anymore, instead only the hash of the Client ID is
3826 hashed. This way we can access the Client ID from the cache
3827 with Client ID but with the hash of the ID (which is a hash of
3828 the nickname) as well without any difference in performance.
3830 Added also silc_idcache_find_by_id_one_ext to do one on one
3831 searching when we have the actual ID. Added also function
3832 silc_hash_client_id_compare. The affected files are
3833 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3835 * When hashing the name associated with a ID it is always done
3836 in lowercase. This way we can access the cache without worrying
3837 about case-sensitivity, even though, for example nicknames are
3840 * Fixed a bug in server with channel message sending. It put
3841 wrong ID type as destination ID. The affected file
3842 silcd/packet_send.c.
3844 * silc_idcache_del_by_context now deletes from all hash tables
3845 by context. Affected file lib/silccore/idcache.c.
3847 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Changed the client library to use the new ID Cache interface.
3850 Changes around the source tree.
3852 * Added silc_hash_table_rehash_ext to rehash with specific
3853 hash function. Affected file lib/silcutil/silchashtable.[ch].
3855 * Added silc_hash_string_compare to compare two strings in the
3856 hash table. Affected file lib/silcutil/silcutil.[ch].
3858 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added new function silc_idcache_del_by_context into the
3861 lib/silccore/idcache.[ch].
3863 * Changed the server's ID list routines to use the new ID Cache
3864 interface. Changes around the source tree.
3866 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Added silc_hash_table_del[_by_context]_ext functions in to the
3869 lib/silcutil/silchashtable.[ch].
3871 Removed silc_hash_table_find_all* routines and added new
3872 silc_hash_table_find_foreach to replace them.
3874 Added silc_hash_table_replace_ext function as extended
3875 replacing function. Separated the simple hash table interface
3876 from the extended hash table interface in the file
3877 lib/silcutil/silchashtable.h.
3879 * Fixed minor bugs and changed it to use some of the new
3880 hash table functions in lib/silccore/idcache.c
3882 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Added new function silc_hash_table_find_all to return all keys
3885 in the hash table by the specified key. As the hash table is
3886 collision resistant it also makes it possible to have several
3887 duplicate keys in the hash table. This function may be used to
3888 find all of the keys from the hash.
3890 Added user_context arguments to the SilcHashFunction,
3891 SilcHashCompare and SilcHashDestructor to deliver user specified
3894 Added new fuctions silc_hash_table_find[_all]_ext to do
3895 extended lookup with specified hash and compare functions and
3896 specified user contexts.
3898 Added new function silc_hash_table_add_ext to add the key
3899 with specified hash function and user context.
3901 Added new function silc_hash_table_foreach to traverse all
3902 entrys in the hash table. Added SilcHashForeach callback
3905 Added new function silc_hash_table_del_by_context to delete
3906 the entry only if the context associated with the key matches.
3908 Affected files are lib/silcutil/silchashtable.[ch].
3910 * Removed silc_hash_[server/client/channel]_id and added just
3911 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3912 silc_hash_id_compare to compare two ID's using as the hash table
3913 comparison function. Added also silc_hash_data to hash
3914 binary data and silc_hash_data_compare to compare it.
3916 * Removed silc_idlist_find_client_by_hash as it is not needed
3917 anymore. Affected file silcd/idlist.[ch].
3919 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3920 to use internally the SilcHashTable. The new ID Cache is a lot
3921 faster than the old one. Some of the ID Cache interface was also
3922 rewritten and obsolete and stupid functions were removed.
3924 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Added entry_count field to the SilcHashTable to keep the number
3927 of the entries in the table. Implemented the function
3928 silc_hash_table_rehash. Added new function
3929 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3931 Fixed a minor bug in silc_hash_table_free.
3933 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3934 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3935 into the lib/silcutil/silcutil.[ch].
3937 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Implemented a collision resistant hash table into the
3940 lib/silcutil/silchashtable[ch]. See the header and the source
3941 for the SilcHashTable API.
3943 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Merged dotconf version 1.0.2 into lib/dotconf.
3947 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Do not compile anything in lib/silcsim/* if the SIM support
3950 is not enabled. The tree should now compile without problems
3953 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Compiled the SILC under cygwin. Compiled and tested briefly
3956 without problems. More tests needed. The SIMs didn't compile
3959 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3961 * Fixed possible crash in silc_get_username in the
3962 lib/silcutil/silcutil.c.
3964 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Fixed a va_arg in silc/client_ops.c.
3968 * Oops, RC5 routines were named AES and caused some problems
3969 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3971 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Added new SilcIDIP structure into the lib/silccore/id.h and
3974 replaced the old `ip' fields from all SILC ID's to that type.
3975 This is a step towards IPv6 support.
3977 The silc_id_get_len takes now the ID as an extra argument.
3978 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3979 both IPv4 and IPv6 based ID's.
3981 The affected files are lib/silccore/id.[ch] and other files
3982 around the tree using these routines.
3984 * Removed the ID length arguments in server from various
3985 silc_server_send_notify_* routines -> they are not needed
3988 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Fixed memory leak in silc_encode_pem_file in the file
3991 lib/silcutil/silcutil.c.
3993 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Check minor version as well in the SKE. Affected files are
3996 silcd/protocol.c and lib/silcclient/protocol.c.
3998 * Added --identifier option to the server so that an identifier
3999 can be when creating the public key for the server. Affected
4000 file is silcd/silcd.c.
4002 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4003 lib/silccrypt/silcpkcs.c.
4005 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Register default ciphers and stuff when using -C option with
4008 the server. Affected file sildc/silcd.c.
4010 * Put back the servers public key filename format, it is better
4011 than the new one. For now, the client keys are saved with the
4012 new filename format. The affected file silc/client_ops.c.
4014 * Implemented the Cipher API for the rest of the ciphers that
4015 did not implement it or implemented it the wrong way.
4017 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4019 * Register default ciphers and stuff when using the -S option
4020 in the client. Affected file silc/silc.c. Same also when
4021 creating new key pair with -C option.
4023 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Fixed the silc_verify_public_key client operation function to
4026 save the public keys differently. The fingerprint is now
4027 used as filename and not the hostname. This way also the
4028 client keys are saved uniquely and not with hostnames. The
4029 affected file is silc/client_ops.c.
4031 * Trimmed the silc_hash_fingerprint function to remove extra
4032 whitespaces from the end of the fingerprint. The affected
4033 file is lib/silccrypt/silchash.c.
4037 * Added silc_cipher_register_default function to register all
4038 default ciphers. It can be used when configuration files
4039 does not exist and the application does not want any specific
4040 ciphers in any specific order.
4042 The SilcDList is now used as silc_cipher_list dynamically
4043 allocated cipher list. Removed the static list all together
4044 and now all ciphers must be allocated to the dynamic list.
4045 The silc_cipher_alloc routine was changed to check only the
4048 All silc_cipher_* routines that used to return int returns
4051 The affected files lib/silccrypt/silccrypt.[ch].
4053 * The same thing was done to silc_hash_* as for silc_cipher_*
4054 routines. Affected files lib/silccrypt/silchash.[ch].
4056 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4057 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4058 Added also silc_pkcs_[un]register[_default] functions.
4059 Removed the data_context from the PKCS API.
4061 * Added silc_hmac_register_default function to register default
4062 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4063 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4064 to unregister all hmacs at once.
4066 * Register the default ciphers, hash functions, PKCSs and HMACs
4067 if client's configuration file does not exist. The affected
4070 * The client did not load the hash functions from the SIM
4071 modules at all. Added support for this. Affected file is
4072 silc/clientconfig.c.
4074 * When decoding public key with silc_pkcs_public_key_decode, check
4075 the supported algorithm only if PKCS are registered. Affected
4076 file lib/silccrypt/silcpkcs.c. The same was done with the
4077 silc_pkcs_private_key_decode.
4079 * Fixed the SILC List routines to keep the list always in order.
4080 It used to change the list's order when traversing the list but
4081 not it preserves the order. Affected file lib/trq/silclist.h.
4083 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Added the client library to use the SilcSocketConnection's
4086 reference counter (by silc_socket_dup) to prevent the bug that
4087 the socket object may be freed underneath async operation.
4089 * The name resolv library checking fixes in the configure.in.pre.
4092 * Created new version of the protocol drafts for future
4093 development. The -03 drafts are the ones that will be changed
4094 in the trunk now and the -02 will remain as they are.
4096 * Send list of CUMODE notifys to the router when announcing
4097 the channel users to the router. Affected file silcd/server.c.
4098 If the router receiving channel founder CUMODE for a channel
4099 that already has channel founder it will send CUMODE notify
4100 to the sender to remove the channel founder rights from the
4101 announced client. Affected file silcd/packet_receive.c.
4103 * The CUMODE notify may now use Server ID as well as the entity
4104 who changes the mode. Updated protocool specs.
4106 * Updated INSTALL and README files.
4108 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * New web pages in the http://silc.pspt.fi. The pages was
4115 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Implemented the [DenyConnectin] config section in the server.
4118 Added silc_server_config_denied_conn to check whether incoming
4119 connection is denied. Affected file silcd/serverconfig.[ch].
4121 * Do not check the ports when checking the incoming configuration
4122 data if the port is 0, meaning any. Affected file is
4123 silcd/serverconfig.c.
4125 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Fixed buffer overflow in silc_string_compare in the file
4128 lib/silcutil/silcutil.c.
4130 * Fixed double free in silc_server_command_leave in the file
4133 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Fixed the version checking in the server. Affected file is
4138 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Fixed the configuration data fetching when accepting new
4141 connections in the server. Affected file silcd/server.c.
4143 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Added `sender_entry' argument to the function
4146 silc_server_packet_relay_to_channel so that we can check
4147 whether some destination actually belongs to the same route
4148 the sender belongs (ie, we must not resend the packet to the
4149 sender). Affected file silcd/packet_send.[ch].
4151 * Added `servername' field to the SilcClientEntry in the server
4152 to hold the name of the server where client is from. Affected
4153 file is silcd/idlist.h.
4155 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Moved the channel message encrypting in the router betwen
4158 router connections from silc_server_channel_message to the
4159 silc_server_packet_relay_to_channel since we want to check
4160 whether we have anybody channel before encrypting anything.
4161 Affected files silcd/packet_[receive/send].c.
4163 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Fixed the [AdminConnection] server config section to support
4166 multiple entries. Affected file silcd/serverconfig.c.
4168 * Added support into the server to check the validity of the
4169 incoming connection before executing any KE or authentication
4172 * The connection configuration is now saved to the KE and
4173 connection auth protocol contexts and not fetched anymore in
4174 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4176 * The local hosts listenning address and port is also resolved
4177 now when starting the server. We want to have the socket object
4178 to include the real address and port for the listener. Added
4179 new function silc_net_check_local_by_sock into the files
4180 lib/silcutil/silcnet.[ch].
4182 * Fixed a broadcast bug in server -> do not broadcast if we
4185 * Fixed a routing bug. Do not route broadcast packets ever.
4186 Broadcast packets must be processed always and not routed since
4187 they may be destined to some other host than yourself and thus
4188 would get routed without no good reason. Affected file is
4191 * Added function silc_server_config_is_primary_route to check
4192 whether primary router connection has been configured (a router
4193 configuration that we are initiating). If there is not, we
4194 will assume that there is only two routers in the SILC network
4195 and we will use the incoming router connection as our primary
4196 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4198 * Changed the order of the broadcasting. Broadcast _after_ the
4199 packet has been processed not before. Affected file is
4202 * Fixed a [ClientConnection] parsing bug. The port was never
4203 parsed correctly thus resulting to port 0. Affected file
4204 silcd/serverconfig.c.
4206 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4207 argument and did not set the broadcast packet flag. Affected
4208 file silcd/packet_send.c. Fixed same bug in the function
4209 silc_server_send_notify as well.
4211 * If we receive NEW_ID packet for our own ID in the server, ignore
4214 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Removed the nickname from the Private Message Payload.
4219 Updated the code and the protocol specs.
4221 * Updated protocol specs for submitting to the IETF.
4223 * Tweaked the Random Number Generator a bit. Affected file
4224 lib/silccrypt/silcrng.c. Exported a new function
4225 silc_rng_[global]_add_noise which can be used to add more
4228 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Do not parse packets with different timeout when protocol
4231 is active -> may cause problem with rekey. Affected file
4234 * When server receives signoff notify it must not create
4235 new channel key if the client is on any channels since the
4236 sender of the signoff notify will create it.
4238 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Added printing of error messages during SKE protocol from the
4241 failure packet sent by server during SKE. Affected file
4244 * Removed the client's failure_callback handling with timeout
4245 and handle it immediately when received.
4247 * The SKE library returned wrong type in SUCCESS and FAILURE
4248 packets. They must be 32 bit MSB not 16 bit MSB.
4250 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Ok, rewrote the logic of the re-key and now it seems to work.
4253 I tested it on high traffic with frequent re-keys without
4254 problems. Added hmac_receive (and renamed hmac to hmac_send)
4255 in SilcClientConnection in lib/silcclient/client.h and
4256 in SilcIDListData in silcd/idlist.h. Also, removed the
4257 SilcPacketParserContext's cipher and hmac fields as they are
4258 not needed anymore and actually caused some problems when
4259 the ciphers and hmac's changed underneath the packet parser.
4261 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * If re-key protocol is active then process the incoming packets
4264 synchronously since we must assure that icoming packets encrypted
4265 with the old key is processed before the new keys is set to
4266 use. This is true other packets than for REKEY packets.
4267 Affected file silcd/server.c. The same was done to client library
4268 as well, affected file lib/silcclient/client.c.
4270 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Fixed bug in client and server to accept the force send if
4273 the packet is send from silc_[server/client]_packet_process
4274 function. Otherwise the packets are never delivered, oops.
4276 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Disable force sending of packets when REKEY protocol is active.
4279 We must assure that no packet is sent directly when rekey is
4280 performed. All packets must be sent through packet queue.
4281 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4282 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4283 function is silc_[server/client]_packet_send_real to check
4286 * Replaced the SIM paths from example config files to
4287 /usr/local/modules. Also, make install creates now
4288 /usr/local/silc/logs directory to hold all the SILC server
4291 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Made the configure.in.pre work on Solaris. Patch by salo.
4295 * Made all ciphers compatible with non-x86 machines. Defined
4296 CBC mode macros into lib/silccrypt/ciphers_def.h.
4298 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Fixed the make install.
4302 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * When MAC computation fails the silc_packet_decrypt returned 0
4305 even though it was supposed to return -1. Fixed this. The
4306 affected file is lib/silccore/silcpacket.c.
4308 * Do not replace the config files in /etc/silc (in make install)
4309 if they already exist. Affected file ./Makefile.am.
4311 * Do not send re-key packets immediately but through packet queue.
4312 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4314 * Changed silc_net_check_host_by_sock to return FALSE if the
4315 IP/DNS could not be resolved. Though, it returns the IP address
4316 now even if it could not resolve it (but returns also FALSE).
4317 Affected file lib/silcutil/silcnet.[ch].
4319 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Added silc_pkcs_decode_identifier to decode the public key's
4322 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4323 Added also silc_pkcs_free_identifier. Added also new context
4324 SilcPublicKeyIdentifier.
4326 * Added -S option to the silc client. It is used to dump the
4327 contents of the specified public key file.
4329 * Changed the PKCS api to return the public key length when
4330 setting the public key.
4332 * Fixed a fatal bug in the public and private key file loading.
4333 Affected file lib/silccrypt/silcpkcs.c.
4335 * Execute the packet parsing for client with zero (0) timeout
4336 if the protocol is active. Affected file silcd/server.c.
4338 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Made the key generation options to the silcd program. Added
4341 -C option, equivalent to client's option.
4343 * Added new [ServerKeys] config section to the server. It
4344 configures the server's public and private key.
4346 * Defined generic Public Key Payload into the protocol
4347 specification to send specific type of public keys and
4350 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4351 public key or certificate.
4353 * Implemented the GETKEY command to the server and to the
4354 client library and on user interface.
4356 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Made preliminary `make install' work.
4360 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Added SilcServerRekey context into silcd/idlist.h.
4364 * Added the PFS support as defined in the specification to the
4365 SKE protocol. Affected files lib/silcske/*.c.
4367 * Added `ske_group' field to the SilcServerRekey context to hold
4368 the number of the SKE group that is used with PFS in re-key.
4369 Affected file silcd/idlist.h.
4371 * Added PFS re-key support to the server. Affected file is
4374 * Added silc_protocol_cancel to cancel execution of the next
4375 state of the protocol. Affected file is
4376 lib/silccore/silcprotocol.[ch].
4378 * Added the re-key support with and without PFS to the client
4379 library. Re-key is performed once in an hour, by default.
4381 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4382 Added silc_client_rekey_callback and silc_client_rekey_final.
4383 Affected files are lib/silcclient/protocol.[ch] and
4384 lib/silcclient/client.[ch].
4386 * Removed the `hmac_key' and `hmac_key_len' fields from the
4387 SilcClientConnection structure; not needed. Affected file is
4388 lib/silcclient/client.h.
4392 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Do not ask whether user wants to use the negotiated private key
4395 for private messages, just use it. Affected file is
4396 silc/local_command.c.
4398 * Added `send_enc_key' and `enc_key_len' fields to the
4399 SilcIDListData structure since they are needed in the re-key
4400 phase. Affected file is silcd/idlist.[ch].
4402 * Implemented the simple re-key protocol into the server.
4403 Affected files silcd/server.c and silcd/protocol.[ch]. The
4404 re-key will be performed once in an hour, by default.
4406 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4407 Added silc_server_rekey, silc_server_rekey_callback and
4408 silc_server_rekey_final.
4410 * Removed Tunneled flag from the protocol. Updated the code
4411 and the specifications.
4413 * Adde `pfs' field to the SilcIDListData to indicate whether
4414 the PFS is to be performed in the re-key. Affected file is
4417 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4420 int64 of at least the xintXX size. If void * is less that 4
4421 bytes uint32 * will be used. Defined bool as boolean.
4423 * Changed _ALL_ unsigned long and unsigned int to uint32,
4424 unsgined short to uint16 in the source tree.
4426 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4427 not handle clients that has entry->data.registered == FALSE.
4428 They are not in the network anymore. Affected file is
4431 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Implemented the sending of the SERVER_SIGNOFF notify in the
4434 server. Affected file is silcd/server.c.
4436 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4437 Added also silc_notify_payload_encode_args into the
4438 lib/silccore/silcnotify.[ch].
4440 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4441 Affected file silcd/packet_receive.c.
4443 * Implemented the SERVER_SIGNOFF notify handling in the client
4444 library. Affected file lib/silcclient/client_notify.c. Also,
4445 implemnted the printing of the SERVER_SIGNOFF info to the
4446 application. Affected file silc/client_ops.c.
4448 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4449 if the deleting was successful. Affected file silcd/idlist.[ch].
4451 * Added support for public key authentication in the connection
4452 authentication protocol in the client library. Affected file
4453 lib/silcclient/protocol.c.
4455 * Changed the server's silc_idlist_get_clients_by_* interface
4456 to support already allocated array so that new entries may be
4457 added to pre-allocated array. Affected file silcd/idlist.[ch].
4458 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4459 and command replies.
4461 * All command reply functions in the server now calls the
4462 pending command callback even if error occured. This way the
4463 error will be delivered to the client as well. Affected files
4464 silcd/command.c and silcd/command_reply.c.
4466 * Fixed INFO command to return local server's info if no server
4467 was provided. Affected file lib/silcclient/command.c.
4469 * Removed RESTART command for good. Updated the code and the
4472 * Rewrote parts of the task system. It is a bit simpler now.
4473 Removed unsued task priorities. The affected files are
4474 lib/silcutil/silctask.[ch].
4476 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Moved the USERS printing from the library to the application.
4479 Affected files lib/silcclient/command.c and silc/client_ops.c.
4481 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Added channel key re-key support. The re-key is perfomed
4486 only by the router and is done once in an hour. Added `rekey'
4487 field to the SilcChannelEntry in the server. Affected files
4488 silcd/server.c and silcd/idlist.h.
4490 * Added silc_task_unregister_by_context into the file
4491 lib/silcutil/silctask.[ch].
4493 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Added SILC_UMODE_GONE mode to indicate when the client is not
4496 present in the SILC network. Added also support to the local
4497 command AWAY that will set this mode. Added support of showing
4498 "xxx is gone" in WHOIS command. The USERS command shows the
4499 gone status as well.
4501 * Fixed setting server and router operator privileges in the
4502 server's UMODE command. Affected file silcd/command.c.
4504 * Merged the SKE KE1 and KE2 payloads into one payload. The
4505 new KE payload is equivalent to the old KE2 payload.
4507 Cleaned up the SKE Start Payload parsing. It now uses the
4508 simple buffer unformatting to do the parsing. A lot faster
4511 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4512 to the SKE that is used to indicate whether both of the SKE
4513 parties should perform authentication. By default only the
4514 responder performs authentication. By setting this flag also
4515 the initiator must do authentication. By default it is unset
4516 since in normal SKE case, client to server connection, only
4517 the responder should do authentication. When doing SKE between
4518 two clients both should perform authentication. Updated the
4519 code and the protocol specs.
4521 * A little fix to IDENTIFY command in the server. Search the
4522 client first by hash not nickname. Affected file is
4525 * Fixed the silc_client_close_connection to support closing
4526 the client to client connections wihtout deleting too much
4527 data. Affected file lib/silcclient/client.c.
4529 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4530 are received if protocol used to be active but is not anymore
4531 the application would crash due to NULL pointer dereference.
4532 Affected files silcd/server.c and lib/silcclient/client.c.
4534 * Added `hash' field to the SilcClientConnection to include
4535 the hash function negotiated in the SKE protocol.
4537 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4538 to set the channel founder authentication data. A client can
4539 claim the founder rights later by providing the authentication
4540 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4541 This way the channel founder can regain the channel founder
4542 privileges even it is left the channel. This works only on
4543 local server and the client must be connected to the same
4544 server to be able to regain the founder rights. Updated the
4545 protocol specs accordingly.
4547 Added support to the CMODE command in the client to set the
4548 founder auth data. Read the README to see how to set it.
4550 Added support to the CUMODE command to claim the founder
4551 rights. Read the README to see how to do it.
4553 Added support for the founder authentication to the Channel
4554 Entry in the server. Affected file silcd/idlist.h.
4556 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4557 server's CMODE command. Affected file silcd/command.c.
4559 * Added the following new functions into lib/silccore/silcauth.[ch]:
4560 silc_auth_get_method and silc_auth_get_data.
4562 * The server now saves the remote hosts public key to the
4563 SilcIDListData pointer. Affected file silcd/protocol.c.
4565 * The normal server now does not remove the channel entry from
4566 the cache if the founder authentication data is set. It used
4567 to remove it if the founder was the last one on the channel on
4568 the server and left the channel. The auth data is saved and
4569 if the channel is re-joined later the old entry is used with
4570 the old auth data. Affected files silcd/command_reply.c and
4573 * Removed the `pkcs' field from the SilcIDListData structure
4574 in the server; it is not used. Affected file silcd/idlist.h.
4576 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Fixed packet processing on slow links. Partial packets were
4579 never re-processed because the incoming data buffer was cleared
4580 by the application. Application must not directly clear the
4581 sock->inbuf, the packet processing routines handle it. Fixed
4582 this in client library and in server.
4584 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Fixed the WHOIS and IDENTIFY send reply function to really
4587 check whether to send list or just one entry. Affected file
4590 * Cleaned up the LEAVE command's channel key distribution. The
4591 affected file silcd/command.c.
4593 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4594 can enforce the channel mode as well. In that case the ID
4595 includes the ID of the server. The code now enforces the
4596 mode change if the router have different mode than the server.
4598 * The notify client operation with CMODE_CHANGE notify can now
4599 return NULL client_entry pointer if the CMODE was not changed
4600 by client. Application must check for this.
4602 * Added <Server ID> argument to INFO command to support server
4603 info fetching by Server ID.
4605 * Added silc_server_announce_get_channel_users to get assembled
4606 packets of channel users of the specified channel. Affected
4607 file silcd/server.[ch].
4609 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4610 was freed underneath the ID Cache.
4612 * Re-announce clients when the server received CHANNEL_CHANGE
4613 notify from the router. Affected file silcd/packet_send.c.
4615 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4618 crashed since it did not handle the fact that there is no cipher
4619 called "3" and didn't check the error condition. Now fixed.
4621 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4622 flag. It can be used to send message requests.
4624 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Implemented the RESTART command in the client.
4628 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4629 notice type messages. Added notice printing to the user
4632 * The channel keys are not re-generated if the channel's mode
4633 is PRIVKEY, ie private key on the channel exists. Affected
4634 files silcd/server.c and silcd/command.c.
4636 * Fixed a little bug in channel message delivery when channel
4637 private keys are set in the server. Affected file is
4638 silcd/packet_send.c.
4640 * Changed the setting on channel->on_channel = TRUE from the
4641 silc_client_save_channel_key to the JOIN command reply. The
4642 key payload is not received if the private channel key is set.
4643 Affected file lib/silcclient/command_reply.c and the
4644 lib/silcclient/client_channel.c.
4646 * When the CMODE_CHANGE notify is sent and the channel private
4647 key mode is removed the channel key must be re-generated in
4648 other cells as well. Added this support for the router in the
4649 silcd/packet_receive.c.
4651 * Added new local command NOTICE to send notice message on
4652 channel. Affected file silc/local_command.[ch].
4654 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Added new local command ME to the client. It is used to send
4657 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4658 some action. Affected file silc/local_command.[ch].
4660 * Changed channel_message and private_message client operations
4661 to deliver the message flags to the application. Added also
4662 the `flags' arguments to the silc_client_send_channel_message
4663 and silc_client_send_private_message functions. Affected file
4666 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Redefined the Private Message Payload to support private message
4669 keys and to support the new private message flags. Updated
4670 the protocol specs. Flags makes it possible to have for example
4671 CTCP style messages.
4673 * Added new type SilcPrivateMessagePayload and defined an API
4674 for it in the lib/silcclient/silcprivate.[ch].
4676 * Tested private message private keys successfully. Tested the
4677 private message key set, unset and list commands with the new
4680 * Redefined the Channel Message Payload to include the channel
4681 message flags (equal with private message flags) to support
4682 for example CTCP style messages.
4684 * Defined some of the message (for channel and private message)
4685 flags. Updated the protocol specs and added the flags to the
4686 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4688 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Added SilcKeyAgreementStatus type to the key agreement routines
4691 to indicate the current status and error if one occured.
4692 The status types are defined in the lib/silcclient/silcapi.h.
4694 * Added new local command KEY that is used to set and unset private
4695 keys for channels, set and unset private keys for private messages
4696 with remote clients and to send key agreement requests and
4697 negotiate the key agreement protocol with remote client. The
4698 key agreement is supported only to negotiate private message keys,
4699 it currently cannot be used to negotiate private keys for channels,
4700 as it is not convenient for that purpose.
4702 * Fixed a minor pending callback setting bug in the function
4703 silc_client_get_client_by_id_resolve, now the function works.
4704 Affected file lib/silcclient/idlist.c.
4706 * Added function silc_net_get_local_port to get local bound
4707 port by socket. Added to lib/silcutil/silcnet.[ch].
4709 * Added `sockets' and `sockets_count' fields to the SilcClient
4710 object. They hold the sockets of the listenning sockets in
4711 the client. Listenning sockets may be for example the key
4712 agreement server. Affected file lib/silcclient/client.[ch].
4713 Added functions the silc_client_add_socket and the
4714 silc_client_del_socket. They are exported to the application
4717 * Added ~./silc/clientkeys to support other client's public keys.
4719 * Renamed verify_server_key client operation to verify_public_key
4720 and added one argument to indicate the type of the connection
4721 (server, client etc.).
4723 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Added silc_server_connection_auth_request to handle the
4726 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4727 silcd/packet_receive.[ch].
4729 * Added silc_server_send_connection_auth_request into the
4730 silcd/packet_send.c to send the connection auth request packet.
4732 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4735 * Fixed the public key authentication in responder side in the
4736 server. The `auth_data' pointer includes the SilcPublicKey
4737 not the path to the public key. Affected file silcd/protocol.c.
4739 * Implemented the public key authentication in the initiator side
4740 in the server. Affected file silcd/protocol.c.
4742 * Removed the [RedirectClient] config section from the server
4743 configuration. Is not needed and I don't want to implement it.
4745 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Cleaned up the CMODE command in the server. It now works
4748 correctly and supports all the modes defined in the protocol.
4749 Affected file is silcd/command.c.
4751 * Added `hmac_name' field to the SilcChannelEntry in the server
4752 to hold the default HMAC of the channel. It can be set when
4753 creating the channel (with JOIN command). Affected files
4756 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4757 type to indicate the change of the current cipher and hmac
4758 on the channel. Client can safely ignore the <cipher> argument
4759 (if it chooses to do so) since the CHANNEL_KEY packet will
4760 force the channel key change anyway. The <hmac> argument is
4761 important since the client is responsible of setting the new
4762 HMAC and the hmac key into use.
4764 * Fixed the CMODE command in the client library as well.
4766 * Tested CMODE command in router environment successfully.
4768 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Show the version of the remote client (or server) when connecting
4771 to the server. It is logged to the log file. Affected file
4772 is silcd/protocol.c.
4774 * Fixed the KILLED notify handling in the client library. The
4775 client must be removed from all channels when receiving the
4778 Also, do not remove the client entry when giving the KILL
4779 command but when the KILLED notify is received.
4781 * Removed silc_idlist_find_client_by_nickname from the server.
4782 Not needed anymore. Affected files silcd/idlist.[ch].
4784 * Implemented the CHANNEL_CHANGE notify type handling to the
4785 server. Affected file silcd/server.c.
4789 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4792 notify between routers.
4794 * Implemented the INVITE command correctly to the server.
4796 * Implemented the INVITE notify type handling in the server.
4798 * Implemented the INVITE command to the client library and on the
4801 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Added function silc_server_get_client_resolve to find the
4804 client entry by ID from all ID lists and then resolve it
4805 (using WHOIS) if it cannot be found. Affected file is
4808 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Implemented the BAN command to the client library.
4812 * The JOIN command in the server now checks the invite list
4815 * Changed the silc_command_reply_payload_encode_va and the
4816 silc_command_payload_encode_va to support that if argument is
4817 NULL it ignores and checks the next argument. Affected file
4818 lib/silccore/silccommand.c.
4820 * Added silc_server_send_notify_ban to send the BAN notify
4821 type between routers.
4823 * Chaned the silc_notify_payload_encode to support that if
4824 argument is NULL it ignores and checks the next argument.
4825 Affected file lib/silccore/silcnotify.c.
4827 * Tested ban lists in router environment successfully.
4829 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Implemented BAN command to the server, in silcd/command.[ch].
4833 * Removed the BAN and INVITE_LIST modes from the CMODE command
4836 * Added function silc_string_match to regex match two strings.
4837 Affected files lib/silcutil/silcutil.[ch].
4839 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Redefined parts of the SilcChannelEntry in the server to support
4842 the new ban and invite lists.
4844 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Redefined the INVITE command. The same command can be used to
4847 invite individuals to the channel but also to manage the invite
4848 list of the channel (to add to and remove from the invite list).
4849 Updated the protocol specs.
4851 * Added new command SILC_COMMAND_BAN that can be used to manage
4852 the ban list of the channel. Updated the protocol specs.
4854 * Removed the channel modes: the SILC_CMODE_BAN and the
4855 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4856 in the CMODE command. The equivalent features are now available
4857 using INVITE and BAN commands. Updated the protocol specs.
4859 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4860 in the network about change in the current ban list. The notify
4861 type is not used by the client.
4863 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4864 support the invite lists.
4866 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Added new function silc_string_regexify that converts string
4869 including wildcard characters into regex string that can
4870 be used by the GNU regex library. Added into the file
4871 lib/silcutil/silcutil.[ch].
4873 Added silc_string_regex_combine to combine to regex strings
4874 into one so that they can be used as one regex string by
4875 the GNU regex library. Added into the file
4876 lib/silcutil/silcutil.[ch].
4878 Added silc_string_regex_match to match two strings. It returns
4879 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4881 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Imported GNU regex to the soruce tree into lib/contrib.
4884 Fixed some compiler warning from the regex.c.
4886 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Fixed MOTD command in the server to work in router environment.
4890 * Fixed the MOTD command in the client library to support
4891 the server argument in the command.
4893 * Added `nickname_len' argument to the silc_idlist_add_client
4894 in the server, as the `nickname' argument may be binary data
4897 * Added silc_idlist_get_channels to return all channels from
4900 * Implemented LIST command to the server. Affected file is
4903 * Implemented the LIST command to the client library and on the
4906 * Added [<user count>] argument to the LIST command reply.
4907 With private channels the user count is not shown.
4909 * Updated TODO and README.
4911 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * The client entry's data.registered must be TRUE even with
4914 global client entry on global client list. The data.registered
4915 is used to check whether the client is anymore in the network,
4916 for example with WHOWAS command so it must be valid.
4918 * Fixed the WHOWAS command in the server. It now actually works
4919 in router environment. Added function into silcd/command_reply.c
4920 silc_server_command_reply_whowas_save.
4922 * Added silc_idlist_purge function to the silcd/idlist.c
4923 to periodically purge the ID Cache.
4925 * Fixed INFO command in the server. It works now in router
4926 environment. Added <server name> argument to the INFO command
4927 reply. Updated the protocol specs.
4929 * Fixed minor bug in silc_idcache_purge to not purge if the
4930 expire value is zero.
4932 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4933 they were buggy because of the WHOWAS information.
4935 * Fixed local command MSG to handle the async resolving of
4936 the remote client properly. It used to fail the first MSG.
4937 Affected file silc/local_command.c.
4939 * Added `data_len' field to SilcIDCache context.
4941 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Update TODO. Todo in commands in the server.
4945 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4948 used by routers as broadcast packet to inform other routers
4949 about the changed user mode.
4951 Implemented the notify handling in the server. Affected file is
4952 silcd/packet_receive.c. Added the function
4953 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4955 * Added new generic Channel Payload and deprecated the New Channel
4956 Payload. The New Channel Payload is now the generic Channel
4959 * Added new argument `mode' to the silc_server_send_new_channel
4960 as it is required in the Channel Payload now.
4962 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4963 and created a new and real SilChannelPayload to represent the
4964 new generic Channel Payload. Implemented the encode/decode
4965 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4967 * Added silc_server_get_client_channel_list to return the list
4968 of channels the client has joined for WHOIS command reply.
4969 Affected file silcd/server.[ch].
4971 * Implemented the channel list sending in the WHOIS command reply
4972 in server and in the client.
4974 Implemented the channel list displaying on the user interface
4975 as well. Affected file silc/client_ops.c.
4977 * Added silc_channel_payload_parse_list to parse list of Channel
4978 Payloads. It returns SilcDList list of SilcChannelPayloads.
4979 Client for example can use this function to parse the list of
4980 channels it receives in the WHOIS command reply. The caller
4981 must free the list by calling silc_channel_payload_list_free.
4982 Affected files lib/silccore/silcchannel.[ch].
4984 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Added one new argument <user mode> to the WHOIS command reply
4987 to return the mode of the user in SILC. Updated the protocol
4990 Implemented it to the server and client.
4992 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Fixed the mode printing on the user interface on joining.
4995 Affected file silc/client_ops.c.
4997 * Implemented the UMODE command and user modes in general to the
4998 client library and to the user interface.
5000 * Implemented the UMODE command to the server.
5002 * The server now sends UNKNOWN_COMMAND error status if client sends
5003 unknown command. Affected file silcd/command.c.
5005 * All server commands now handle the command identifier the right
5006 way when sending the command reply to the client. The client can
5007 use to identify the command replies with the identifier.
5009 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added silc_server_get_client_route to resolve the route to
5012 the client indicated by the client ID. Affected file is
5015 * Added silc_server_relay_packet as general function to relay
5016 packet to arbitrary destination. This deprecates functions
5017 like _send_private_message_key, _relay_notify etc. Affected
5018 file is silcd/packet_send.[ch].
5020 Removed silc_server_send_key_agreement,
5021 silc_server_send_private_message_key and
5022 silc_server_packet_relay_notify functions from the file
5023 silcd/packet_send.[ch].
5027 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5028 server. Affected file silcd/packet_receive.[ch].
5030 * Implemented the KILL command to the client. Implemented the
5031 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5032 Affected files lib/silcclient/command[_reply].c and
5033 lib/silcclient/client_notify.c. Implemented the KILL notify
5034 printing in the user inteface.
5036 * Fixed a lot silc_parse_nick memory leaks from the client
5037 library in the file lib/silcclient/command.c.
5039 * Changed the silc_server_send_notify_on_channels's `sender'
5040 argument from SilcSocketConnection to SilcClientEntry to
5041 check the sender as entry and not as connection object and not
5042 to send to the client provided as argument. The affected file
5043 is silcd/packet_send.[ch].
5045 * The notify packets that are destined directly to the client used
5046 to not to be processed by the server. Now changed that and the
5047 server processes all notify packets. After relaying the packet
5048 to the client the notify packet is processed in the server.
5050 * The silc_server_free_client_data now checks whether there is
5051 pending outgoing traffic for the client and purges the data to
5052 the network before removing the client entry.
5054 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5057 an client is killed from the SILC Network. Updated the protocol
5060 Added new function silc_server_send_notify_killed to the
5061 silcd/packet_send.[ch].
5063 * Added function silc_server_packet_relay_notify to relay notify
5064 packets that are destined directly to a client. In this case
5065 the server does not process the notify packets but merely relays
5066 it to the client. Affected file silcd/packet_send.[ch].
5068 Added also silc_server_packet_process_relay_notify to check
5069 whereto relay the notify. Affected file is
5070 silcd/packet_receive.[ch].
5072 * Implemented the KILL command to the server.
5076 * Added the backup schema desgined last fall to the protocol
5077 specs for everyone to see. The specification is in the
5078 *-spec-xx.txt draft and the packet type definitions for the
5079 backup routers is in *-pp-xx.txt draft. Thusly, added also
5080 new packet type SILC_PACKET_CELL_ROUTERS.
5082 * A big security problem in the implementation discovered. The
5083 signoff of an client did not cause new channel key generation
5084 which it of course should've done. The channel keys must be
5085 always re-generated when client leaves (or signoffs) the channel.
5086 The silc_server_remove_from_channels funtion now handles
5087 the channel key re-generation.
5089 * Added `sender' argument to the silc_server_send_notify_on_channels
5090 to not to send the client provided as argument. Affected file
5091 silcd/packet_send.[ch].
5093 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Implemented OPER and SILCOPER commands into the server and
5098 * Added silc_auth_verify and silc_auth_verify_data to verify
5099 the authentication directly from the authentication payload.
5100 It supports verifying both passphrase and public key based
5101 authentication. Affected file lib/silccore/silcauth.[ch].
5103 * Added `hash' field to the SilcIDListData structure. It is the
5104 hash negotiated in the SKE protocol. Affected file is
5107 * Slight redesigning of the SilcAuthPayload handling routines.
5108 Do not send SilcPKCS but SilcPublicKey as argument.
5110 * Implemented the public key authentication support to the
5111 serverconfig. The public key is loaded from the provided path
5112 and saved as authentication data to void * pointer. Thus,
5113 changed the unsigned char *auth_data to void *auth_data;
5115 * Fixed SHUTDOWN command to send the reply before the server
5116 is shutdown. :) Affected file silcd/command.c.
5118 * Fixed fatal bug in CONNECT command. The hostname was invalid
5119 memory and server crashed. Affected file silcd/command.c.
5121 * Fixed fatal bug in CLOSE command. The server_entry became
5122 invalid but was referenced later in the command. Affected file
5125 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Fixed fatal bug in failure packet handling. Server ignored
5128 the failure and thus crashed when it came.
5132 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5135 that the command may be executed only once in (about) 2 seconds.
5136 The old SILC_CF_LAG flag is same but allows command bursts up
5137 to five before limiting.
5139 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5140 server code. Various commands now includes the CF_LAG_STRICT
5141 flag to disallow any kind of miss-use of the command.
5143 * Fixed the silc_buffer_unformat to not to allocate any data
5144 if the length of the data is zero. It used to allocate the
5145 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5147 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Changed the format of AdminConnection configuration section
5150 in the server. Added username of the admin to the format.
5151 Affected files silcd/serverconfig.[ch].
5153 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5154 to return admin configuration data by host, username and/or
5157 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Implemented WHOWAS command to the server. Added the functions:
5161 silc_server_command_whowas_parse,
5162 silc_server_command_whowas_send_reply,
5163 silc_server_command_whowas_from_client and
5164 silc_server_command_whowas_from_server
5166 * Added <Client ID> argument to the WHOWAS command reply. Updated
5167 the protocol specs accordingly.
5169 * Implemented WHOWAS command and command_reply to the client
5172 Implemented the WHOWAS printing on the user interface.
5174 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Added new argument to the WHOWAS command reply, the real name.
5177 It is an optional argument. Updated the protocol specs.
5179 * Added SilcIDCacheDestructor callback that is registered when
5180 the SilcIDCache is allocated. The callback is called when
5181 an cache entry in the ID Cache expires, or is purged from the
5182 cache. Added into lib/silccore/idcache.[ch].
5184 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5185 to destruct the client entries when the cache entry expires.
5186 Other ID Cache's in server and in the client library ignores
5189 * If the ID Cache entry's `expire' field is zero then the entry
5190 never expires. Added boolean `expire' argument to the
5191 silc_idcache_add function in the lib/silccore/idcache.[ch].
5192 If it is TRUE the default expiry value is used.
5194 * Added silc_server_free_client_data_timeout that is registered
5195 when client disconnects. By default for 5 minutes we preserve
5196 the client entry for history - for WHOWAS command.
5198 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Added support to the server to enforce that commands are not
5201 executed more than once in 2 seconds. If server receives
5202 commands from client more frequently, timeout is registered
5203 to process the commands. Affected file silcd/command.c.
5204 Added new function silc_server_command_process_timeout.
5206 * Changed NICK_NOTIFY handling in client library to check that
5207 if the client's nickname was changed, so there is no need to
5208 resolve anything from the server.
5210 * Removed error printing from the WHOIS and IDENTIFY commands.
5211 If error occurs then it is ignored silently in the client library.
5212 The application, however, may map the received error to
5213 human readable error string. The application currently maps
5214 the NO_SUCH_NICKNAME error to string.
5216 * Made the command status message public to the application. Moved
5217 them from lib/silcclient/command_reply.c to
5218 lib/silcclient/command_reply.h. The application can map the
5219 received command status to the string with the
5220 silc_client_command_status_message function.
5222 * Added check to the server to check that client's ID is same
5223 as the Source ID in the packet the client sent. They must
5226 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Added dist-bzip hook to the Makefile.am to make bzip2
5229 compressed distributions.
5231 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Server now enforces the maximum length for the nickname and
5234 the channel as protocol specification dictates. 128 bytes for
5235 nickname and 256 bytes for channel name.
5237 * Moved the WHOIS printing to the application. The client libary
5238 does not print out the WHOIS information anymore, the application
5239 must do it. Renamed silc_client_command_reply_whois_print to
5240 the silc_client_command_reply_whois_save.
5242 The client's idle time is also sent to the application now, and
5243 the idle is shown on screen.
5245 * Added silc_client_command_reply_identify_save to save the
5246 received IDENTIFY entries.
5248 * Do not check for channel private keys in message sending and
5249 reception if the channel does not have the PRIVKEY mode set.
5250 Affected file lib/silclient/client_channel.c.
5252 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5255 just surfaced after chaning the JOIN procedure.
5257 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5259 * Added silc_client_get_clients_by_list to get client entries
5260 from Client ID list, that is returned for example by JOIN
5261 and USERS command replies. The application should use this
5262 function for example when JOIN command reply is received to
5263 resolve the clients already on the channel (library does not
5264 do that anymore as USERS command reply is not used in the JOIN
5265 procedure anymore). Affected files lib/silcclient/silcapi.h and
5266 lib/silcclient/idlist.c.
5268 * JOIN command reply and USERS command reply returns now SilcBuffer
5269 pointers instead of unsigned char pointers when returning
5270 the client list and mode list.
5272 * Added <Client ID> argument to the JOIN command reply, mainly
5273 for the server to identify for which client the command was
5274 originally sent. Updated protocol specs accordingly.
5276 * Added SilcDlist private_key pointer to the SilcChannelEntry
5277 in the client to support the channel private keys. Affected
5278 file is lib/silcclient/idlist.h.
5280 * Added SilcChannelPrivateKey argument to the function
5281 silc_client_send_channel_message so that application can choose
5282 to use specific private ke if it wants to. If it is not provided,
5283 the normal channel key is used, unless private keys are set.
5284 In this case the first (key that was added first) is used
5285 as the encryption key.
5287 * Implemented the support for channel private key handling.
5288 Implemented the following functions:
5290 silc_client_add_channel_private_key,
5291 silc_client_del_channel_private_keys,
5292 silc_client_del_channel_private_key,
5293 silc_client_list_channel_private_keys and
5294 silc_client_free_channel_private_keys
5296 Affected file lib/silcclient/client_channel.c.
5298 * Added the support for the private keys in the channel message
5299 sending and encryption and in the message reception and
5300 decryption. Affected funtions are
5301 silc_client_send_channel_message and silc_client_channel_message.
5303 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Added SKE's key verify callback to the client library's
5306 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5308 * Removed the statement that server (or router) must send USERS
5309 command reply when joining to the channel so that the client
5310 knows who are on the channel. Instead, the client list and
5311 client's mode list is now sent in the JOIN command reply to the
5312 client who joined channel. This is better solution.
5314 * Added function silc_server_get_users_on_channel and function
5315 silc_server_save_users_on_channel to the silcd/server.[ch].
5317 * Removed function silc_server_command_send_users from the
5320 * Do not show topic on the client library anymore. The topic is
5321 sent in the command reply notify to the application and the
5322 application must show the topic now.
5324 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Added client searching by nickname hash into the IDENTIFY and
5327 WHOIS commands in the server as they were clearly missing from
5328 them. Affected file is silcd/command.c.
5330 * Fixed a bug in private message receiving in the client library.
5331 The remote ID was freed and it wasn't supposed, now it is
5334 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5336 * Minor fix to the channel payload; allocate the data area, as it
5337 needs to be of specific length.
5339 * If the key agreement port is zero then the operating
5340 system will define the bound port. Affected files are
5341 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5343 * Added new function silc_channel_payload_decrypt into the file
5344 lib/silccore/silcchannel.[ch].
5346 * Moved the channel message etc, check from silc_packet_decrypt
5347 to applications. The library calls now a generic
5348 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5349 when the packet is either normal or special. This was done to
5350 allow more wide range of checking that was not allowed when
5351 the code was in library. Now applications can do virtually any
5352 checks to the packet and return to the library the decision how
5353 the packet should be processed. Affected files are
5354 lib/silccore/silcpacket.[ch].
5356 Added silc_server_packet_decrypt_check to the server and
5357 silc_client_packet_decrypt_check to the client library.
5359 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5360 to send with specified source and destination information.
5362 * Channel message delivery between routers was broken after the
5363 channel key distribution was fixed earlier. The channel key
5364 was used be to distributed to other routers as well which is not
5365 allowed by the protocol. Now this is fixed and channel keys
5366 really are cell specific and the channel message delivery between
5367 routers comply with the protocol specification.
5369 * Fixed various commands in server to check also the global list
5370 for the channel entry and not just the local list. The affected
5371 file silcd/command.c.
5373 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Added assert()s to buffer formatting and unformatting routines
5376 to assert (if --enable-debug) when error occurs. Affected
5377 file: lib/silcutil/silcbuffmt.c.
5379 * Changed to auto-reconnect to check whether the remote host is
5380 router and register the re-connect timeout if it is. It used
5381 to check that whether we are normal server, but router must do
5382 auto-reconnect with another router as well. Affected file
5385 * Removed the [<key len>] option from CMODE command as the cipher
5386 name decides the key length, nowadays. See the defined ciphers
5387 from the protocol specification.
5389 * Added [<hmac>] option to the CMODE command to define the HMAC
5390 for the channel. Added SILC_CMODE_HMAC channel mode.
5392 * Added [<hmac>] option for the JOIN command so that user can
5393 select which HMAC is used to compute the MACs of the channel
5396 * Added Hmac field to the Channel Message Payload. The integrity
5397 of plaintext channel messages are now protected by computing
5398 MAC of the message and attaching the MAC to the payload. The
5399 MAC is encrypted. Now, it is clear that this causes some
5400 overhead to the size of the packet but rationale for this is that
5401 now the receiver can verify whether the channel message decrypted
5402 correctly and also when private keys are set for the channel the
5403 receiver can decrypt the packet with several keys and check from
5404 the MAC which key decrypted the message correctly.
5406 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5407 lib/silccrypt/silccipher.[ch].
5409 * Added silc_hash_len to return the digest length into the
5410 lib/silcrypt/silchash.[ch].
5412 * Rewrote parts of Silc Channel Payload interface in the
5413 lib/silccore/silcchannel.[ch]. The encode function now also
5414 encrypts the packet and parse function decrypts it.
5416 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Fixed a minor formatting bug in the SKE's key material processing.
5419 It actually might have processed the keys wrong way resulting
5422 * Redefined the mandatory HMAC algorithms and added new algorithms.
5423 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5424 and hmac-md5 truncated to 96 bits. The mandatory is now
5425 hmac-sha1-96. Rest are optional (including the one that used
5426 to be mandatory). Rationale for this is that the truncated HMAC
5427 length is sufficient from security point of view and can actually
5428 make the attack against the HMAC harder. Also, the truncated
5429 HMAC causes less overhead to the packets. See the RFC2104 for
5432 * Added new [hmac] configuration section. The SKE used to use
5433 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5434 is of course wrong. The official names that must be proposed in
5435 the SKE are the ones defined in the protocol specification
5436 (hmac-sha1-96 for example). The user can configure any hmac
5437 using any hash function configured in the [hash] section. At
5438 least, the mandatory must be configured.
5440 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5442 * Added HMAC list to the SKE proposal list. It has now both
5443 hash algorithm list and HMAC list. This makes the protocol
5444 incompatible with previous versions. The SKE now seems to work
5445 the way it is supposed to work, for the first time actually.
5447 * Defined plain Hash algorithms to the protocol specification.
5450 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Implemented support for key agreement packets into the server.
5453 Added functions silc_server_key_agreement and
5454 silc_server_send_key_agreement. Other than these functions,
5455 server has nothing to do with this packet.
5457 * Added support for private message key packets into the server.
5458 Added functions silc_server_private_message_key and
5459 silc_server_send_private_message_key.
5463 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5464 called in the protocol's final callback instead in the END
5465 protocol state. This makes a little more sense and in the same
5466 time in client we can use the same protocol routines for normal
5467 key exchange and to key agreement packet handling as well.
5469 * Added to both client's and server's KE protocol context the
5470 SilcSKEKeyMaterial pointer to save the key material. We will
5471 bring the key material to the protocol's final callback by doing
5472 this. The final callback must free the key material.
5474 * Added SKE's packet_send callback into client's KE protocol
5475 context so that the caller can choose what packet sending function
5476 is used. This way we can use different packet sending when
5477 doing normal SKE when doing key agreement packet handling (in
5478 the key agreement packet handling we do not want to encrypt
5481 * Implemented the responder side of the key agreement routines
5482 in the client. The client can now bind to specified port and
5483 accept incoming key negotiation. The key material is passed
5484 to the application after the protocol is over.
5486 * Implemented the processing of incoming Key Agreement packet
5487 in the client. Added function silc_client_key_agreement to
5490 * Implemented the intiator side of the key agreement routines
5491 in the client. The client can now initiate key agreement with
5492 another remote client. The key material is passed to the
5493 application after the protocol is over.
5495 * Created client_keyagr.c to include all the key agreement
5498 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5499 SILC_TASK_CALLBACK except that it is not static.
5501 * Created client_notify.c and moved the Notify packet handling
5502 from the client.[ch] into that file.
5504 * Created client_prvmsg.c and moved all private message and
5505 private message key routines from the client.[ch] into that file.
5507 * Create client_channel.c and moved all channel message and
5508 channel private key routines from the client.[ch] into that file.
5510 * Changed silc_client_get_client_by_id_resolve to resolve with
5511 WHOIS command instead of IDENTIFY command, in the file
5512 lib/silclient/idlist.c.
5514 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Implemented the SKE's responder side to the Client library.
5518 * When FAILURE is received to the protocol do not trust it
5519 blindly. Register a timeout to wait whether the remote closes
5520 the connection as it should do it, only after that process the
5521 actual failure. This was changed to both client and server.
5523 * Added client_internal.h to include some of the structures
5524 there instead of client.h in lib/silcclient/.
5526 * Added function silc_task_unregister_by_callback to unregister
5527 timeouts by the callback function.
5529 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Some "Incomplete WHOIS info" errors has been appearing on the
5532 log files. Took away the entry->userinfo check from WHOIS
5533 reply sending. The entry->userinfo is now " " if client did not
5534 provide one. I thought this was fixed earlier but something
5535 is wrong still. Let's see if the error still appears.
5537 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Fixed a minor bug in the login when the channel key is
5540 re-generated in the server. It used to generate the key in
5541 wrong order and thus caused problems in the channel traffic.
5543 * Fixed a minor bug in channel key distsribution after
5544 KICK command. The key was not sent to the router even though
5547 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Added silc_ske_process_key_material_data as generic routine
5550 to process any key material as the SILC protocol dictates. The
5551 function is used by the actual SKE library but can be used by
5552 applications as well. This relates to the private message keys
5553 and the channel private keys since they must be processed the
5554 same way the normal SILC session keys. The protocol dictates
5555 this. Affected files: lib/silcske/silcske.[ch].
5557 Added also silc_ske_free_key_material to free the
5558 SilcSKEKeyMaterial structure.
5560 * Defined silc_cipher_set_key function to set the key for
5561 cipher without using the object's method function. The affected
5562 files: lib/silccrypt/silccipher.[ch].
5564 * Implemented silc silc_client_add_private_message_key,
5565 silc_client_add_private_message_key_ske,
5566 silc_client_del_private_message_key,
5567 silc_client_list_private_message_keys and
5568 silc_client_free_private_message_keys functions in the
5571 Added functions silc_client_send_private_message_key to send
5572 the Private Message Key payload and silc_client_private_message_key
5573 to handle incoming Private Message Key payload.
5575 * Added Cipher field to the Private Message Key payload to set
5576 the cipher to be used. If ignored, the default cipher defined
5577 in the SILC protocol (aes-256-cbc) is used.
5579 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Removed lib/silcclient/ops.h file.
5583 Redefined parts of the SILC Client Library API. Created new
5584 file silcapi.h that deprecates the ops.h file and defines the
5585 published Client Library API. Defined also private message key
5586 API and channel private key API into the file.
5588 This is the file that the application must include from the
5589 SILC Client Library. Other files need not be included by
5590 the application anymore.
5592 * Added new key_agreement client operation callback and also
5593 defined the Key Agreement library API for the application.
5595 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5598 is used by clients to request key negotiation between another
5599 client in the SILC network. If the negotiation is started it
5600 is performed using the SKE protocol. The result of the
5601 negotiation, the secret key material, can be used for example
5602 as private message key.
5604 Implemented the Key Agreement payload into the files
5605 lib/silccore/silauth.[ch].
5607 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Redefined ciphers for the SILC protocol. Added some new ciphers
5610 and defined the key lengths for the algorithms. Changed the
5611 code accordingly. The default key length is now 256 bits.
5613 * Fixed SKE key distribution function silc_ske_process_key_material
5614 when the key length is more than 128 bits. The default key
5615 length in SILC is now 256 bits.
5617 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5618 to indicate unsupported algorithm.
5620 * Renamed rijndael.c to aes.c and all functions as well.
5622 * Fixed a long standing channel key setting bug in client library.
5623 Weird that it has never surfaced before.
5625 * Fixed bug in channel deletion. If the entire channel is removed
5626 then it must also delete the references of the channel entry
5627 from the client's channel list as the client's channel entry and
5628 the channel's client entry share same memory.
5630 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Implemented CONNECT and SHUTDOWN commands in the client.
5634 * Implemented CLOSE command to the client.
5636 * Added the function silc_idlist_find_server_by_name into the
5637 files silcd/idlist.[ch].
5639 Added the function silc_idlist_find_server_by_conn into the
5640 files silcd/idlist.[ch].
5642 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * DIE command was renamed to SHUTDOWN. Updated the both code
5647 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5648 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5650 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5653 * Added function silc_server_create_connection function to create
5654 connection to remote router. My server implementation actually
5655 does not allow router to connect to normal server (it expects
5656 that normal server always initiates the connection to the router)
5657 so the CONNECT command is only good for connecting to another
5660 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5663 or some other client was kicked from the channel.
5665 Implemented the handling of the notify type to both client
5668 Implemented silc_server_send_notify_kicked to send the KICKED
5669 notify. It is used to send it to the server's primary router.
5671 * Implemented the KICK command into server and client.
5673 * Added `query' argument to the silc_idlist_get_client function
5674 to indicate whether to query the client from server or not if
5677 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5678 to indicate that the client is not channel founder.
5682 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Removed the rng context from SilcPacketContext structure and
5685 changed that the packet routine uses the Global RNG API.
5687 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Added support for quit message that client can "leave" on the
5690 channel when it quits the SILC. It is ditributed inside the
5691 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5693 Added silc_server_free_client_data that will take the
5694 signoff message as argument.
5696 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5698 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Updated parts of the protocol specification to keep it up
5703 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5706 payloads in one packet.
5708 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5709 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5710 use now the new List flag.
5712 * Also deprecated the following packet types: REPLACE_ID,
5713 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5715 * Added list support for Notify packet in server.
5717 * Added silc_server_send_notify_channel_change to send the
5718 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5719 the silc_server_send_replace_id.
5721 * Added silc_server_send_notify_nick_change to send the
5722 NICK_CHANGE notify type. Deprecates the function
5723 silc_server_send_replace_id.
5725 * Added silc_server_send_notify_join to send the JOIN notify type.
5726 Deprecates the function silc_server_send_new_channel_user.
5728 * Added silc_server_send_notify_leave to send LEAVE notify type.
5729 Deprecates the function silc_server_send_remove_channel_user.
5731 * Added silc_server_send_notify_cmode and
5732 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5733 types. Deprecates the silc_server_send_set_mode function.
5735 * Added SERVER_SIGNOFF notify type to indicate that server has
5736 quit. This means that all clients on the channel from that
5737 server will drop. This can be also used when netsplit happens.
5739 Deprecated REMOVE_ID packet type since it is not needed anymore
5742 Added silc_server_send_notify_server_signoff to send the
5743 SERVER_SIGNOFF notify type. Deprecates the function
5744 silc_server_send_remove_id.
5746 Added also silc_server_send_notify_signoff to send the
5747 SIGNOFF notify type.
5749 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5750 SILC protocol from this day on. Changed the protocol
5751 specification as well.
5753 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5754 notify type. It is used between routers to notify about
5755 topic changes on a channel.
5757 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5760 * Partly updated the protocol specification to comply with the
5761 changes now made. It is still though a bit outdated.
5763 * The JOIN notify type now takes one extra argument <Channel ID>.
5764 The packet used to be destined to the channel but now the
5765 JOIN type may be sent as list thus it is impossible to
5766 destine it to any specific channel. By adding this argument
5767 it is again possible.
5769 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added CREDITS file. The CHANGES and CREDITS file will appear
5772 in the distribution as well.
5774 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5777 types in the server's silcd/packet_receive.c.
5779 * Implemented CMODE and CUMODE to work in router environment.
5781 * Fixed minor encoding and decoding buglet from the
5782 lib/silccore/silcmode.c.
5784 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5787 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5789 * Changed all SilcConfigServer* and silc_config_server* to
5790 SilcServerConfig* and silc_server_config*, respectively.
5793 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Associated the ID (client or server ID) to the Authentication
5796 Payload to avoid any possibility of forging. Updated the
5797 protocol specification and the code accordingly.
5799 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * The RSA key length is now save to the RsaKey context in the
5802 key generation process in lib/silccrypt/rsa.c. The key length
5803 is now used to figure out the maximum size of the block allowed
5804 to be encrypted/signed.
5806 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5807 is equivalent to the silc_mp_mp2bin but does not allocate any
5810 * Changed silc_mp_mp2bin API to take length argument. If it is
5811 non-zero then the buffer is allocated that large. If zero, then
5812 the size is approximated using silc_mp_sizeinbase, which however
5815 * Created Global RNG API which is global RNG that application can
5816 initialize. After initializing, any routine anywhere in the
5817 code (including library) can use RNG without allocating a new
5818 RNG object. This was done to allow this sort of use of the
5819 RNG in code that has no chance to allocate RNG object. All
5820 applications currently allocate this and many routines in the
5821 library use this. Affected file lib/silccrypt/silcrng.[ch].
5823 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5824 it to use the Global RNG API.
5826 * Defined Authentication Payload into protocol specification that
5827 is used during SILC session to authenticate entities. It is
5828 used for example by client to authenticate itself to the server
5829 to obtain server operator privileges.
5831 Implemented this payload into the lib/silccore/silcauth.[ch].
5832 Implemented also routines for public key based authentication
5833 as the new protocol specification dictates.
5835 Moved definitions of different authentication methods from
5836 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5838 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5839 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5840 silc_pkcs_verify_with_hash functions into the file
5841 lib/silccrypt/silcpkcs.[ch].
5843 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * The client entry's userinfo pointer must be always valid.
5846 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5847 will fail since it requires the userinfo. Now, the userinfo
5848 is allocated as "" if actual userinfo does not exist. Actually,
5849 it must exist and it is totally Ok to drop client connections
5850 that does not announce the userinfo. However, we will make
5851 this workaround for now.
5853 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5854 to return the remote port by socket.
5856 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5859 SILC_SERVER_PENDING_EXEC and added an new macro
5860 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5861 data or when error occurs while processing the pending command.
5863 Added new argument `destructor' into silc_server_command_pending
5864 and to the SilcServerCommandPending object. This destructor is
5865 now called after calling the pending callback or if error occurs
5866 immediately. If error occurs the actual pending callback won't
5867 be called at all - only the destructor. The destructor may be
5868 NULL if destructor is not needed.
5870 All this applies for client library code as well. Similar
5871 changes were made there as well for the pending commands.
5873 In the client, the application must now allocate the
5874 SilcClientCommandContext with the silc_client_command_alloc
5877 * Added reference counter to the SilcServerCommandContext. Added
5878 function silc_server_command_alloc and silc_server_command_dup
5881 Same type of functions added to the client library for the same
5884 * Removed the cmd_ident from IDListData away since it is now
5885 global for all connections. It is the command identifier used
5886 in command sending and with pending commands. The affected file
5889 * Added reference counter to the SilcSocketConnection objecet to
5890 indicate the usage count of the object. The object won't be
5891 freed untill the reference counter hits zero. Currently only
5892 server uses this, and client ignores it. The client must be
5893 set to use this too later. The affected files are
5894 lib/silccore/silcsockconn.[ch]. Added also the function
5895 silc_socket_dup to increase the reference counter.
5897 This was mainly added because it is possible that the socket
5898 is removed underneath of pending command or other async
5899 operation. Now it won't be free'd and proper DISCONNECTING
5900 flags, etc. can be set to avoid sending data to connection that
5901 is not valid anymore.
5903 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5904 the connection. After that it sets SILC_SET_DISCONNECTED.
5905 It is, however, possible that the socket data is not still freed.
5906 The silc_server_packet_process now checks that data is not
5907 read or written to connection that is DISCONNECTED. The socket
5908 get's freed when the reference counter hits zero.
5910 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Changed the client operation API: channel_message operation's
5913 `sender' is now the client entry of the sender, not the nickname
5914 and the `channel' is the channel entry, not the channel name.
5916 In the private_message operation the `sender' is now also the
5917 client entry of the sender not the nickname.
5919 Affected file is lib/silcclient/ops.h and all applications
5920 using the client operations.
5922 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Moved the calling of ops->connect() from connect_to_server_final
5925 into receive_new_id functin since that is the point when the
5926 client is actually allowed to send traffic to network. The
5927 affected file is lib/silcclient/client.c.
5929 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5932 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5933 (if needs broadcasting) instead of broadcasting the packets one
5934 by one which would make a burst in the network traffic.
5936 * Added `broadcast' argument to the functions in silcd/server.[ch]
5937 silc_server_create_new_channel[_with_id] to indicate whether
5938 to send New Channel packet to primary router.
5940 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Added new function into the silcd/server.[ch] files:
5943 silc_server_create_new_channel_with_id to create new channel with
5944 already existing Channel ID.
5946 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5947 lib/silccore/silcpacket.h. This packet is used t send list of
5948 Set Mode payloads inside one packet. Server uses this to set
5949 the modes for the channels and clients on those channels, that it
5950 announced to the router when it connected to it. The protocol
5951 specification has been updated accordingly.
5953 * The silc_server_new_channel did not handle the packet coming
5954 from normal server as it normally does not send that. However,
5955 when it announces its channels it does send it. Implemented
5956 the support for that.
5958 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5959 into the file lib/silccore/id.h.
5961 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Fixed memory leaks in the functions silc_idlist_del_client,
5964 silc_idlist_del_channel and silc_idlist_del_server in the file
5965 silcd/idlist.c. All of those leaked like a sieve.
5967 * Fixed some small memory leaks in the client's function
5968 silc_client_notify_by_server.
5970 * Added functions into silcd/server.c: silc_server_announce_clients,
5971 silc_server_announce_channels and silc_server_announce_server.
5972 These functions are used by normal and router server to announce
5973 to its primary router about clients, channels and servers (when
5974 router) that we own. This is done after we've connected to the
5977 These functions effectively implements the following packet types:
5978 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5979 and SILC_PACKET_NEW_ID_LIST.
5981 * Added new functions into the silcd/packet_receive.[ch]:
5982 silc_server_new_id_list, silc_server_new_channel_list and
5983 silc_server_new_channel_user_list to handle the incoming
5984 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5986 * Added support of changing Channel ID in the function
5987 silc_server_replace_id. If the server that announces a channel
5988 to the router already exists in the router (with same name but
5989 with different Channel ID), router is responsible to send
5990 Replace ID packet to the server and force the server to change
5991 the Channel ID to the one router has.
5993 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5994 client that the Channel ID has been changed by the router. The
5995 normal server sends this to the client. Client must start using
5996 the new Channel ID as the channel's ID.
5998 Implemented handling of this new type into lib/silcclient/client.c
5999 into the function silc_client_notify_by_server.
6001 * Added new function silc_idlist_replace_channel_id into the files
6002 silcd/idlist.[ch] to replace the Channel ID.
6004 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Call silc_server_command_identify_check always when processing
6007 the IDENTIFY command in silcd/command.c
6009 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6012 send keepalive packets. The packet can be sent by clients,
6013 servers and routers.
6015 Added function silc_socket_set_heartbeat into the file
6016 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6017 If not set, the heartbeat is not performed. The actual
6018 heartbeat is implemented in the low level socket connection
6019 library. However, application is responsible of actually
6022 Added silc_server_send_heartbeat to send the actual heartbeat
6023 packet into silcd/packet_send.[ch]. Server now performs
6024 keepalive with all connections.
6026 * Added silc_task_get_first function into lib/silcutil/silctask.c
6027 to return the timeout task with shortest timeout. There was a bug
6028 in task unregistration that caused problems. TODO has been
6029 updated to include that task system must be rewritten.
6031 * The client library will now resolve the client information when
6032 receiving JOIN notify from server for client that we know but
6033 have incomplete information.
6035 * Rewrote parts of silc_server_remove_from_channels and
6036 silc_server_remove_from_one_channel as they did not remove the
6037 channel in some circumstances even though they should've.
6039 * Encryption problem encountered in server:
6041 The LEAVE command used to send the Channel Key packet to the
6042 router immediately after generating it. However, the code
6043 had earlier sent Remove Channel user packet but not immediately,
6044 ie. it was put to queue. The order of packets in the router
6045 was that Channel Key packet was first and Remove Channel User
6046 packet was second, even though they were encrypted in the
6047 reverse order. For this reason, MAC check failed. Now, this
6048 is fixed by not sending the Channel Key packet immediately but
6049 putting it to queue. However, this is more fundamental problem:
6050 packets that are in queue should actually not be encrypted
6051 because packets that are sent immediately gets encrypted
6052 actually with wrong IV (and thus MAC check fails). So, packets
6053 that are in queue should be encrypted when they are sent to
6054 the wire and not when they put to the queue.
6056 However, the problem is that the current system has not been
6057 designed to work that way. Instead, the packet is encrypted
6058 as soon as possible and left to the queue. The queue is then
6059 just purged into wire. There won't be any fixes for this
6060 any time soon. So, the current semantic for packet sending
6063 o If you send packet to remote host and do not force the send
6064 (the packet will be in queue) then all subsequent packets to the
6065 same remote host must also be put to the queue. Only after the
6066 queue has been purged is it safe again to force the packet
6069 o If you send all packets immediately then it safe to send
6070 any of subsequent packets through the queue, however, after
6071 the first packet is put to queue then any subsequent packets
6072 must also be put to the queue.
6074 Follow these rules and everything works fine.
6076 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Added new function silc_server_remove_clients_by_server to
6079 remove all client entries from ID list when the server connection
6080 is lost. In this case it is also important to invalidate all
6081 client entires as they hold the invalid server entry. This
6082 fixes fatal bug when server has lost connection and will reconnect
6085 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Made some sanity checks to silc_server_daemonise like to check
6088 whether the requested user and group actually exists.
6090 * Added sanity check to SKE's silc_ske_responder_finish to check
6091 that the public and private key actually is valid.
6093 * Invalidate the client's nickname when receiving Replace ID
6094 packet and the Client ID is being replaced. This means that the
6095 server will query the nickname if someone needs it (client)
6098 * Sort the ID Cache in client library when the ID Cache data
6099 has changed (needs sorting).
6101 * Do not allow for SILC client to create several connections to
6102 several servers. The client does not support windows right now
6103 and generating multiple connections causes weird behaviour.
6105 Irssi-silc client does support windows and can handle several
6106 connections without problems, see: www.irssi.org and SILC plugin.
6108 * Fixed some places where client was added to the IDList. The
6109 rule of thumb is following (in order to get everything right):
6110 If the client is directly connected local client then the
6111 `connection' argument must be set and `router' argument must be
6112 NULL to silc_idlist_add_client function. If the client is not
6113 directly connected client then the `router' argument must
6114 bet set and the `connection' argument must be NULL to the
6115 silc_idlist_add_client function.
6117 * The funtion silc_server_packet_send_local_channel actually did
6118 not check whether the client was locally connected or not. It
6119 does that now. Fixed a bug related to LEAVE command.
6121 * Fixed Remove Channel User payload parsing bug in server's
6122 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6124 * The server's silc_server_save_channel_key now checks also the
6125 global ID list for the channel as it might not be in the local
6126 list. Fixed a bug related to LEAVE command.
6128 * Is this the end of the [<unknown>] buglet that has been lurking
6129 around for a long time? A little for loop fix in server's
6130 silc_server_command_whois_parse that is used by both IDENTIFY
6131 and WHOIS command. At least, this was a clear bug and a cause
6132 of one type of [<unknown>] buglet.
6134 * WHOIS and IDENTIFY commands call the function
6135 silc_server_command_[whois/identify]_check function even if
6136 we are not router server.
6138 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added --with-gmp configuration option. If set the GMP
6141 is always compiled in the SILC source tree. If not set then
6142 it is checked whether the system has the GMP3 installed. If
6143 it has then the GMP won't be compiled (the system's headers
6144 and library is used), if it doesn't have it then the GMP is
6145 compiled in the SILC source tree.
6147 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * Changed RSA private exponent generation to what PKCS #1
6150 suggests. We try to find the smallest possible d by doing
6151 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6152 not security fix but optimization.
6154 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Added new config entry [Identity] to fork the server and run
6157 it as specific user and group. A patch from Bostik.
6159 * Imported Dotconf configuration library into lib/dotconf.
6160 This will be used to create the SILC configuration files later.
6161 It will appear in the distsribution after this commit.
6163 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * A big code auditing weekend happening. Auditing code for
6166 obvious mistakes, bugs and errors. Also, removing any code
6169 Removed files for being obsolete:
6171 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6172 inline in the file lib/silcutil/silcbuffer.h)
6174 o lib/silcutil/silcbufutil.c (the header has inline versions)
6176 Changed code to fix possible error conditions:
6178 o The buffer formatting routines now check that the destination
6179 buffer really has enough space to add the data. This applies for
6180 both buffer formatting and unformatting
6181 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6182 unformatting was changed to accomodate following rules:
6183 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6184 sent to the function while XXX_*STRING will not allocate or copy
6185 the data into the buffer. Instead it sets the pointer from the
6186 buffer into the pointer sent as argument (XXX_*STRING used to
6187 require that the pointer must be allocated already). This change
6188 makes this whole thing a bit more consistent and more optimized
6189 (note that the data returned in the unformatting with XXX_*STRING
6190 must not be freed now). The routines return now -1 on error.
6192 o Tried to find all code that use buffer_format and buffer_unformat
6193 and added return value checking to prevent formatting and
6194 especially unformatting errors and possible subsequent fatal
6197 o Changed ske->x and ske->KEY to mallocated pointers in
6198 lib/silcske/silcske.h. Fixed possible data and memory leak.
6200 o Added return value checking to all *_parse* functions. Fixed
6201 many memory leaks as well.
6203 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6204 so that buffer overflows would not happen. All code now also
6205 checks the return value as it can fail.
6207 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Added reconnection support to server if the normal server looses
6210 its connection to the router (for example if router is rebooted).
6211 The server performs normal reconnection strategy implemented
6212 to the server. Affected file silcd/server.c.
6214 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Added new packet type SILC_PACKET_SET_MODE that is used to
6217 distribute the information about changed modes (for clients,
6218 channels and clients channel modes) to all routers in the
6219 network. Updated the protocol specification accordingly.
6221 Added functions into silcd/packet_send.c and
6222 silcd/packet_receive.c: silc_server_send_set_mode,
6223 silc_server_set_mode.
6225 Added new files silcmode.[ch] into lib/silccore that implements
6226 the encoding and decoding of Set Mode Payload. Added new type
6227 SilcSetModePayload. Moved the definitions of different modes
6228 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6230 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Oops, a little mistake in server's connection authentication
6233 protocol. The protocol is not ended with FAILURE but with
6234 SUCCESS if the authentication is Ok. :) Affected file is
6237 * Implemented NICK_CHANGE notify handling in server in the file
6238 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6239 the local clients on the channel. After the changing nickname
6240 in router environment snhould work and the [<unknown>] nickname
6241 should appear no more.
6243 The silc_server_replace_id function that receives the Replace ID
6244 payload now sends the NICK_CHANGE notify type also in the file
6245 silcd/packet_receive.c
6247 * Changed WHOIS and IDENTIFY command to support the maximum amount
6248 of arguments defined in protocol specs (3328 arguments). This
6249 fixed a bug that caused problems when there were more than three
6252 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Added extra parameter, command identifier, to the
6255 silc_client_send_command so that explicit command identifier
6258 Changed that ID list routines uses specific command identifier
6259 when sending WHOIS/IDENTIFY requests to the server so that they
6260 can be identified when the reply comes back.
6262 Affected files lib/silcclient/command.[ch],
6263 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6265 * Added `sender' argument to silc_server_packet_send_to_channel
6266 to indicaet the sender who originally sent the packet to us
6267 that we are now re-sending. Ignored if NULL. Affected file
6268 silcd/packet_send.[ch].
6270 * Added some server statistics support in silcd/server_internal.h
6271 SilcServerStatistics structure and around the server code. Also
6272 send some nice statistics information when client is connecting
6275 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Fixed channel ID decoding in server's JOIN command reply in
6278 silcd/command_reply.c
6280 * Fixed braodcasting of replace ID payload to not to send it if
6281 we are standalone server in silcd/packet_receive.c.
6283 * Fixed all channel message sending routines to not to send
6284 packets to clients that has router set, since they are routed
6285 separately in the same function earlier. Affects file
6286 silcd/packet_send.c and all channel packet sending functions.
6288 * In USERS reply, res_argv[i] are not allocated, the table
6289 is allocated. Thus changed that free the table, not its
6292 * In server's whois_check and identify_check if the client is
6293 locally connected do not send any WHOIS commands - they are not
6296 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Fixed some minor bugs in client when sending WHOIS command. The
6299 arguments was in wrong order.
6301 * Removed statis function add_to_channel from server in
6302 silcd/command.c that was previously used with the joining but
6305 * Tested USERS command in router environment successfully with two
6306 routers, two servers and two clients.
6308 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Reorganized the USERS command and command reply in client library
6311 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6312 When the command is given by user we register a pending command
6313 callback that will reprocess the command after the reply has been
6314 received from the server. When reprocessing the packet we then
6315 display the information. Thus, the USERS information is displayed
6316 now in the command callback instead of in the command reply
6317 callback. The processing of the command is same as previously
6318 when server has sent the command reply in the JOINing process.
6320 * Added to USERS command in silcd/command_reply.c to join the client,
6321 we didn't use to know about, to the channel after we've created
6322 a client entry for it. Also, for clienet we did know already still
6323 check whether it is on the channel or not and add it if not.
6325 * Removed silc_server_command_join_notify as the function and its
6328 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Changed the client's pending command handling to the same as the
6331 server's pending command handling. It is also now possible to
6332 execute command reply functions from other command reply
6333 function as the function callbacks for commands and command
6334 replies are one and same. The pending commands are not static
6335 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6336 in client connection context. Thus, pending commands are server
6337 connection specific as it is convenient.
6339 Changed the function silc_client_command_pending and
6340 silc_client_command_pending_del and added new function
6341 silc_client_command_pending_check. Removed the
6342 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6345 * Added cmd_ident, current command identifier, to the client
6346 connection context in lib/silcclient/client.h to keep track on
6347 command identifiers used in command sending. Client's command reply
6348 function handling now supports the mandatory command identifiers.
6350 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6351 funtions in client to fully support pending command callbacks.
6353 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6354 as one of the arguments to the application in the command reply
6357 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6358 before first releasing SILC but came back. Now it is removed again
6359 and should come back nomore. The FORWARDED flag was used only
6360 by the JOINing procedure by forwarding the command packet to router.
6361 Now, the JOINing procedure has been changed to more generic (due
6362 to various router environment issues) and FORWARDED is not needed
6363 anymore for anything. The protocol specification is yet to be
6366 Now, removed silc_server_packet_forward from server and the flag
6367 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6369 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Renamed NAMES command to USERS command. The NAMES was named that
6372 due to historical reasons. Now it is renamed. Also, rewrote
6373 parts of the USERS command. The nickname list is not sent anymore
6374 by the server. Only Client ID and mode lists are sent in the USERS
6375 command. Changed this also to the protocol specification.
6377 The client now resolves the names and stuff after it receives
6378 the USERS list from the server when joining to the channel.
6380 * WHOIS and IDENTIFY commands has been changed to support multiple
6381 Client ID's per command. One can now search for multiple users
6382 in the network by sending only one WHOIS or IDENTIFY command.
6383 Changed the code and the protocol specifications.
6385 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6386 uses silc_server_command_whois_parse to parse the request. */
6388 * If normal server, do not parse the WHOIS and IDENTIFY requests
6389 before sending it to the router. Saves some time.
6391 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Fixed JOIN command on client library. Wrong number of arguments
6394 used to crash the client.
6396 * Added silc_server_channel_has_global function to check whether
6397 channel has global users or not.
6399 * Added silc_server_channel_has_local function to check whether channel
6400 has locally connected clients on the channel.
6402 * The silc_server_remove_from_one_channel now checks whether the
6403 channel has global users or not after given client was removed from
6404 the channel. It also checks whether the channel has local clients
6405 on the channel anymore. If it does not have then the channel entry
6406 is removed as it is not needed anymore.
6408 * The silc_server_notify now checks on JOIN notify whether the joining
6409 client is one of locally connected or global. If it is global then
6410 the channel has now global users on the channel and that is marked
6411 to the channel entry. Also, it now saves the global client to
6412 global list who is joining and JOINs it to the channel. This is
6413 for normal server, that is.
6415 Changed silc_server_send_notify_on_channel,
6416 silc_server_packet_relay_to_channel and
6417 silc_server_packet_send_to_channel check if we are normal server
6418 and client has router set (ie. global client) do not send the
6419 message to that client, as it is already routed to our router.
6421 * Implemented LEAVE notify type handling in silc_server_notify
6424 * Tested LEAVE command in router environment successfully. Tested
6425 with two routers, two servers and two clients.
6429 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6431 * Implemented SIGNOFF notify type handling in silc_server_notify
6434 * silc_server_remove_id now removes the client entry from all channels
6435 it has joined and thusly sends SIGNOFF notify type.
6437 * Rewrote the NAMES list generation in server by removing two excess
6438 loops. The lists are created now inside one loop.
6440 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6442 * silc_server_remove_channel_user checks now also global list
6443 for channel and client.
6445 * silc_server_new_channel_user checks now both local and global
6446 list for channel and client. Fixed a bug in client id decoding.
6447 Used to decode wrong buffer.
6449 * silc_server_channel_message checks now both local and global
6450 list for channel entry.
6452 * Tested channel joining (hence JOIN) in router environment
6453 successfully. Tested with two routers, two servers and two
6456 * Tested channel message sending in router environment successfully.
6458 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Added silc_server_save_channel_key into server.[ch] to save the
6461 received channel key in Channel Key payload processing. It is
6462 also used in JOIN command reply handling.
6464 Equivalent function silc_client_save_channel_key added into
6465 client.[ch] into client library.
6467 * Changed JOIN command reply to send information whether the channel
6468 was created or not (is existing already) and the channel key
6469 payload. Changed protocol specs accordingly.
6471 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6472 the request was sent by ID and not by nickname. Crashed on
6475 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6478 now correctly save the received data.
6480 * silc_server_free_sock_user_data now notifies routers in the
6481 network about entities leaving the network.
6483 At the same time implemented functions silc_server_remove_id
6484 and silc_server_send_remove_id to receive and send REMOVE_ID
6485 packets. The packet is used to notify routers in the network
6486 about leaving entities. The ID removed will become invalid in
6489 * Added function silc_idlist_del_server into server. Removes and
6490 free's server entry from ID list.
6492 * silc_server_private_message function now checks, if we are router,
6493 that the destination ID really is valid ID, naturally.
6495 * In router when NEW_ID packet is received (for new client) the
6496 hash of the Client ID is saved in the ID Cache but the
6497 client->nickname is set to NULL, instead of putting the hash
6500 IDENTIFY command now also checks that client->nickname must be
6501 valid. If it is not if will request the data from the server who
6502 owns the client. Added new function
6503 silc_server_command_identify_check.
6505 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6506 to set the command to already allocated Command Payload.
6508 * Tested private message sending in router environment with two
6509 routers, two servers and two clients. Fixed minor bugs and now
6512 * Fixed segfault from client's NAMES command. Used to crash if
6515 * Forwarded packets must not be routed even if it is not destined
6516 to the receiver. Changed server code comply with this.
6518 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Added `require_reverse_mapping' boolean value to ServerParams
6521 structure. If TRUE (not default) the server will require that
6522 the connecting host has fully qualified domain name.
6524 If the reverse mapping is not required and hostname could not be
6525 found the IP address is used as hostname.
6527 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6529 * Implemented version string checking to both client and server.
6530 The check is incomplete currently due to the abnormal version
6531 strings used in development version of SILC.
6533 * Changed all command functions in server to use the new
6536 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Changed char *data to unsigned char *data in ID Cache system to
6539 support binary data as ID Cache data. Changed code to support
6540 binary data in lib/silccore/idcache.c.
6542 * Renamed silc_server_packet_relay_command_reply to
6543 silc_server_command_reply as it is normal packet receiving
6544 function. Rewrote the function to accept command replys for
6545 servers and not only for clients.
6547 * Mark remote router always as registered server if we are connecting
6548 to it. Otherwise, commands sent by the router to us are ignored.
6550 * All ID List find routines now returns the ID Cache Entry pointer
6551 as well if requested.
6553 * WHOIS command works now in router environment, tested with two
6554 routers, two servers and two clients.
6556 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6557 in router environment (as it is almost equivalent to WHOIS) but
6558 hasn't been tested thoroughly. Added new functions:
6560 silc_server_command_identify_parse
6561 silc_server_command_identify_send_reply
6562 silc_server_command_identify_from_client
6563 silc_server_command_identify_from_server
6565 * Disabled route cache adding because adding two different ID's with
6566 same IP replaces the old cache entry thus giving wrong route.
6567 The entry->router->connection is always the fastest route anyway
6568 so route cache may not be needed. Of course, new routes maybe
6569 established after receiving the ID when the entry->router->connection
6570 might not be anymore the most optimal.
6572 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Add route cache for received ID for fast routing.
6576 * Added silc_server_packet_route to route received packet on router
6577 that is not destined to us.
6579 * Renamed silc_server_get_route to silc_server_route_get.
6581 * Added id_string and id_string_len fields into SilcServer to
6582 include encoded ServerID for fast comparing without excess
6583 encoding of the ID's.
6585 * Cleaned up WHOIS command on server side. Added following static
6588 silc_server_command_whois_parse
6589 silc_server_command_whois_check
6590 silc_server_command_whois_send_reply
6591 silc_server_command_whois_from_client
6592 silc_server_command_whois_from_server
6594 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6595 arguments in command replies. All command functions should be
6596 updated to use this macro.
6598 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Minor typo fixes on command reply handling on server.
6602 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Added silc_server_command_add_to_channel internal routine to add
6605 the client to the channel after router has created the channel and
6606 sent command reply to the server.
6608 * Added generic silc_server_send_command to send any command from
6611 * Use static buffer with ID rendering instead of duplicating data.
6613 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Fixed a channel user mode bug when joining to a channel server gave
6616 everybody channel founder rights, oops.
6618 * We mark ourselves as the router of the incoming server connection
6619 if we are router ourselves. This way we can check in some packet
6620 sending functions whether it is locally connected server. For
6621 incoming router connections we put NULL.
6623 * For router sending packets locally means now always sending the
6624 packet cell wide; to local clients and local servers. For normal
6625 server sending packet locally means sending it to only local
6628 * Fixed the JOIN command to really work in router environment. If the
6629 channel is created it is always created by the router. Router is
6630 also responsible of making the initial joining to the channel,
6631 sending JOIN notify to the sending server and distributing
6632 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6633 does not exist server doesn't do anything else but forward the
6634 command to the router which performs everything.
6636 * Added silc_server_send_channel_key function to send the Channel Key
6639 * Added silc_server_create_channel_key to create new channel key. The
6640 channel key is now re-generated everytime someone joins or leaves
6641 a channel, as protocol dictates. Note: channel->key_len is the
6644 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6647 packet_receive.[ch] to separate packet sending and receiving
6648 routines. The server.[ch] now includes everything else including
6649 actual packet processing (writing and reading data) and other
6652 Renamed silc_server_private_message_send_internal to
6653 silc_server_send_private_message. The routine is still though
6654 used only to relay private messages as server does not send
6655 private messages itself.
6657 Renamed silc_server_new_channel to silc_server_create_new_channel
6658 and added new function sicl_server_new_channel that handles the
6659 incoming New Channel packet. Added also new sending function
6660 silc_server_send_new_channel to send New Channel Payload.
6662 * Added new function silc_server_notify to process incoming notify
6663 packet to the server/router. Server may then relay the notify
6664 to clients if needed.
6666 * Added new function silc_server_new_channel_user to process incoming
6667 New Channel User packet. Router will redistribute the packet and
6668 send JOIN notify to its local clients and locally connected servers
6669 if needed. Normal server will send JOIN notify to its local client
6670 on same channel when received this packet. Added also corresponding
6671 sending function silc_server_send_new_channel_user to sent the
6674 * Added boolean route argument to send_notif_to_channel and
6675 packet_send_to_channel functions to attempt to route the packet
6676 if it is TRUE and send only locally if it is FALSE.
6678 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * silc_server_replace_id now broadcasts the received replace ID
6681 packet if it is not broadcast packet already. The router must
6682 broadcast to inform other routers about changed ID.
6684 * Added backpointer to server's router into SilcServer context in
6685 silcd/server_internal.h.
6687 * Fixed silc_server_packet_broadcast to send correct broadcast
6690 * The channel key is now distributed to the local client as soon
6691 as it is received from the router (in router environment) so that
6692 no other packet may be sent for the channel until client has
6695 * silc_server_remove_channel_user now broadcasts the received
6696 Remove Channel User packet if it is not broadcast packet already.
6697 The router must broadcast to inform other routers about removed
6700 * Added users field into SilcPacketContext that is a reference count
6701 of the context. One can increase the reference count by calling
6702 silc_packet_context_dup which is now changed to just increase the
6703 reference count instead of duplicating the data. The reference
6704 count is decresed by calling silc_packet_context_free that will
6705 free the data after the reference count hits zero.
6707 For now on the packet context and everything allocated into it
6708 (including the raw packet from network) must be freed by calling
6709 the new silc_packet_context_free function. Added also new function
6710 silc_packet_context_alloc that must be used now to allocate the
6711 context. This also means that if a routine is asynchronous from
6712 silc_[client/server]_packet_parse_type the packet context must
6713 be duplicated by calling silc_packet_context_dup. Otherwise it
6714 gets free'd after silc_[client/server]_packet_parse_type returns.
6715 Also, one must remember that if packet is duplicated then its
6716 reference count must be decresed by calling the free function as
6717 many times as it was duplicated.
6719 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6720 from both client and server.
6722 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Made joining to a channel working in router environment.
6726 * Cleaned up JOIN command on server side and create function
6727 silc_server_command_join_channel internal routine to make the
6730 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Changed silc_command_pending list to SilcDList. Also, added
6733 `ident' field to SilcServerCommandPending structure to identify
6734 the reply and to call correct callback.
6736 Added silc_server_command_pending_check function to replace the
6737 corresnponding macro. The silc_command_pending list is not
6740 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6741 to set identifier to previously allocated Command Payload. It
6742 is used to set identifier for command when resending Command
6745 * Added silc_command_payload_encode_payload to encode Command
6746 Payload buffer from SilcCommandPayload structure.
6748 * Added silc_argument_payload_encode_payload to encode Argument
6749 payload buffer from SilcArgumentPayload structure.
6751 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Changed WHOIS command to support router connection on server side.
6754 The whois request is always sent to router unless the server is
6755 standalone server. After server has received the reply from the
6756 router will it send the reply to the client.
6758 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6759 broadcast received broadcast packet. The function is used only
6760 by router. The broadcast packet is always sent to the router's
6763 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6764 render given ID to printable string, for log files for example.
6766 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Made basic router to router connections working. At least they
6769 can now connect to each other but nothing really works the way
6770 they are supposed - yet.
6772 * Added new initiator token to RouterConnection configuration
6773 file in silcd/serverconfig.[ch]. It is used to tell whether we
6774 are the initiator to the remote router or whether we'll expect
6775 the other end to connect.
6777 * Moved registering of listener task to silc_server_init, hence
6778 the server starts listenning as soon as it is run, even if it
6779 does not have connections to other routers. Let's see how well
6782 * Changed default connection retry timeouts for more suitable in
6785 * Removed cipher and such arguments from silc_idlist_add_client
6786 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6787 Added new function silc_idlist_add_data to add the keys and stuff
6790 * Added SilcIDListData structure and added it to SilcClientEntry
6791 and SilcServerEntry as their first field in the structure. This
6792 way we can explicitly cast the ID entries to the SilcIDListData
6793 structure and get common data for the entries. In past, we had
6794 to first check what type of connection it is and then cast it to
6795 correct ID entry type. Now, we can directly cast the opaque
6796 pointer to the SilcIDListData (no matter what ID entry it actually
6797 is) and get the data needed.
6799 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6802 in some circumstances even if threre were timeout tasks, though not
6803 IO tasks, but tasks anyway. Now fixed.
6805 * Defined SilcServerConnection structure to hold connection specific
6806 stuff about directly connected servers and routers. The definition
6807 is currently in silcd/server_internal.h. I thought about having
6808 a bit more important role fro this struct but for now it is used
6809 only when connecting to other server (or router actually).
6811 * Added connecting retry support in server when connecting to
6812 router(s). The retry feature implement exponential backoff
6813 algorithm. Also, added SilcServerParams structure to hold default
6814 parameters for server. For now, it include these retry settings
6815 and are hard coded. After server is moded to be as Silc Server
6816 Library this structure will be more important.
6818 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Changed client librarys channel->clients table to SilcList and
6821 changed code accordingly.
6823 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Changed client's channel table to SilcList and changed code
6826 accordingly. Also changed SilcChannelClientEntry to include back-
6827 pointer to the channel so that client entry can use that structure
6828 as list as well and we have fast cross-reference to the channel.
6829 This change dramatically decreased the complexity of channel
6830 handling with client entry and vice versa (removed one extra
6831 loop when searching for channel entry from many functions).
6833 * Changed server->sim from table to SilcDList and changed code
6836 * NAMES command can now be used from user interface. It will show
6837 the user list on the channel, neatly.
6839 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6840 Code now saves realname of the user if it becomes available.
6842 * Renamed configure.in to configure.in.pre and made ./prepare
6843 script to automatically add correct version string to
6844 configure.in which it creates from configure.in.pre.
6846 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * NAMES command reply now shows users mode with the nickname when
6851 * Moved silc_client_ch[u]mode[_char] functions from
6852 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6853 place sucks, they are utility functions and should be in some
6856 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6858 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6861 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added TRQ (efficient deque and list library) into lib/trq. This is
6866 a very good list library that is currently used in the SILC. Defined
6867 SilcList API over the library because I didn't like the API very
6868 much. See lib/trq/silclist.h for the API and examples of how to
6869 use the API. Fixed various places in the code to use the new
6870 SilcList API. The SilcList is meant for lists that has a structure
6871 already defined as a list. It is not suitable to add just some
6872 context to the list (in TRQ, the context is the list actually).
6874 So, I defined SilcDList that can be used for the purpose where
6875 predefined list structure does not exit. This can be used as
6876 such list. Now some context just can be added to the SilcDList.
6877 Currently this list is not used in the SILC just yet, though there
6878 are a lot places where this can replace dynamically allocated
6879 tables and I will fix these places, later, to use SilcDList.
6880 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6881 and use TRQ internally).
6883 Also fixed some annoying warning messages that the original TRQ
6884 code generated. Also minor changes to TRQ's Makefile.in.
6886 * Added support for querying by Client ID to both WHOIS and
6887 IDENTIFY commands into server, as required by the protocol.
6889 * Removed method function pointers from SilcBuffer structure. They
6890 weren't used to anything and just increased the context size for
6891 no good reason. This change also made silc_buffer_alloc and
6892 silc_buffer_free functions inline functions.
6894 * Disabled command flooding detection support until it's fixed so
6895 that it accepts commands in but does not execute them more than once
6898 * Added silc_net_localhost(), to return local hostname, into
6899 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6900 that must be initialized before calling silc_client_init.
6902 * Added new function: silc_server_send_notify_on_channels to send
6903 notify messages to all channels client has joined. It is assured
6904 that the message is sent only once per client.
6906 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6907 lib/silcutil/silcutil.[ch] as silc_format function. The new
6908 function is generic and is used by server as well, not only by
6909 the logging routines.
6911 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6912 the provided version string was not acceptable. Added new function:
6913 silc_ske_check_version into lib/silcske/silcske.h. The function
6914 must be implemented by the application (client or server) and it
6915 does not reside in the SKE library. The function checks the version
6916 string remote end sent.
6918 * Added back pointers (to opaque context and to SilcSocketConnection)
6919 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6921 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6922 duplicate packet context structure.
6924 * Changed `notify' client operation to send same arguments as client
6925 receives from server except for ID's. ID's are mapped to correct
6926 ID entry and that is returned. Also, if channel entry is not sent
6927 by server but the notify is for channel the channel entry is sent
6928 to application (otherwise application doesn't know that it is for
6929 channel (library gets it from packet's Destination ID)).
6931 * Added silc_client_remove_from_channels into client library to
6932 remove a client from all channels it has joined to. Used when
6933 received SIGNOFF notify from server. Added also new function
6934 silc_client_replace_from_channels to replace old ID entry with
6935 new ID entry on all channels. Used when received NICK_CHANGE
6938 * Fixed ID Cache list handling in silc_idlist_get_client in
6939 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6940 to get (or query) client by ID.
6942 * Updated TODO list.
6944 * Added connection authentication status message defined by the
6945 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6946 support for these into the code in client and server side.
6948 * Added generic function silc_client_send_command to send any command
6949 with variable argument list. Application should use this function
6950 to send commands if the command functions provided by the library
6951 does not suite for the application's user interface needs.
6953 * Added new `failure' client operation. Application is notified about
6954 received failure packet if client is executing a protocol. In this
6955 case the protocol's execution has failed.
6957 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6958 is required by the protocol.
6960 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6961 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6964 * Added status flag to SilcSKE object to indicate realtime status
6965 of the SKE protocol.
6967 * Application receives now exactly same command reply arguments as
6968 the library receives from server. However, if ID is received the
6969 corresponding ID entry is returned to the application (eg. Client
6970 ID is mapped to correct SilcClientEntry entry and that is returned).
6971 Changed command_reply client operation due to this change.
6973 * Changed all ID's in commands and in command replys as ID Payloads.
6974 Change affected both client and server side codes.
6976 All ID's sent in SILC network (with execption of ID's in SILC
6977 Packet header) are sent in ID Payload to support variable length
6980 * Server now notifies nick changes and notifies all clients on
6981 the channels about the new nickname (about the new Client ID,
6984 * Implemented CMODE command to change channel modes. Supports all
6985 channel modes defined by the protocol specs except ban and invite
6986 lists. (Also, private channel key mode is supported but support for
6987 setting private channel key in client is missing, thus, this mode
6988 has no effect on client side (except that server requires that the
6989 client uses private channel key and normal channel traffic does not
6992 Also, invite mode works per se, but INVITE command does not work
6993 yet correctly, so you can set channel as invite only channel but
6994 inviting clients to the channel does not work (it is yet to be
6995 thought what's the best way to do it).
6997 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6998 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6999 Implemented CUMODE command to change user's mode on the channel.
7000 Supports all modes defined by the protocol specs.
7002 * Added NAMES command reply to return users modes on the channel.
7004 * Removed unnecessary and slow ciphers from lib/silccrypt.
7006 * Set SO_KEEPALIVE option to connection sockets by default.
7008 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7010 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7011 redefined the Notify Payload into protocol specs.
7013 * Added silc_id_payload_parse_id to get ID directly from raw
7016 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7019 accept searching by Client ID as well.
7021 * Added support for LEAVE and SIGNOFF notify types in client library.
7023 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7024 to parse ID Payload from raw data.
7026 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Added flags parameter into silc_ske_assemble_security_properties
7029 function in lib/silcske/silcske.[ch].
7031 * Changed notify client operation to fit better for notify messages
7032 sent by server. The notify payload received from server is now
7033 passed to the application (after parsing it to SilcNotifyPayload).
7034 It is application's responsibility to retrieve the arguments
7035 from the payload and show the message the way it wants. The message
7036 sent by server is implementation specific.
7038 * Changed public keys to comply with the protocol specification.
7039 Old public keys are not supported anymore and are not compatible.
7041 * Removed nickname from Channel Payload as the latest draft removed
7042 it. The client must resolve the nickname from the NAMES command
7043 reply received when it joined the channel.
7045 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7047 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Fixed some errors in protocol specification drafts.
7051 * Created lib/silccore/silcnotify.c to implement Notify Payload
7052 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7053 generic payloads described by protocol specifications. The file
7054 includes implementations for ID Payload and Argument Payload.
7056 * Changed Command Payload implementation to use the new Argument
7057 Payload. Changed command_xxxx_payload to command_payload_xxxx
7058 to comply with SILC coding conventions.
7060 * Added suppport for Argument Payload handling in Notify Payload
7061 implementation as protocol requires it. Added the new support
7062 into server and client lib as well.
7064 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * Added support for multiple nicknames on same channel. [n] is
7067 added locally to the nickname if there are more than one same
7068 nicknames on the channel.
7070 * Server now sends all nicknames that matched WHOIS request.
7071 Client also shows the list received from server.
7073 * Added TOPIC command to client side. User can now set and show
7074 current topic on channel.
7076 * Added MOTD command to client and server. Also, server sends the
7077 motd when client connects to the server.
7079 * Changed version strings to comply ISO 8601.
7081 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Fixed protocol error handling in client library. It should now
7084 cope even if the SKE fails for some reason.
7086 * Made new protocol specification drafts for submitting to IETF.
7088 * Implemented TOPIC command to server in silcd/command.c.
7090 * Added two new notify types into lib/silccore/silcnotify.h:
7091 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7092 notify nickname change and topic setting/change on a channel.
7094 * API change of command_reply operation in client library. The
7095 application gets now the status type received from server as well.
7097 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7101 * Cras fixed and optimized the packet handling even further and
7102 it should work now. Minor change to the prototype of function
7103 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7105 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * Added new function into lib/silcutil/silcschedule.[ch]:
7108 silc_schedule_with_fd to select() a specified fd. The function
7109 returns after timeout expires or data arrives or goes. The
7110 function is used by packet routines to wait that all data is
7111 received from network.
7113 * Fixed data reading from network in lib/silccore/silcpacket.c.
7114 The code now assures that all data is read from the fd and then
7115 continues packet processing. This was a bug fix since the code
7116 used to drop some data in some circumstances.
7118 * Added new function into lib/silcclient/client.[ch]:
7119 silc_client_start_key_exchange to start key exchange after
7120 connection has been established to server. The code internally
7121 now uses this funtion but its main purpose was to provide it
7122 for applications that perform their own connecting. After
7123 application has created a connection it merely calls this
7124 function to start the key exchange between client and server.
7125 The library takes care of everything else after that.
7127 Updated also lib/silcclient/README to explain the usage of
7130 * Do not send to application information that connection has
7131 been established. Application gets notified it by connect
7134 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Applied cras's patch to add silc_schedule_one function. The
7137 function runs scheduler once and returns.
7139 * Fixed the scheduler after cras messed it up. The timeout
7140 handling works now as it's supposed to work.
7142 * Added into lib/silccore/ silcnotify.h to include notify
7143 message types support. Changed silc_server_send_notify*
7144 functions, in server.[ch], to support those new notify types.
7145 Added the support for the notify types into client library,
7146 as well. Added new notify client operation into ops.h in
7149 * Changed silc_server_packet_send_to_channel to send normal
7150 packets instead of just channel message packets. The function
7151 is now used to send the notify packets to channels. It is not
7152 used to send channel message packets anymore, as server never
7155 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7156 va_arg()s as it seems to require it nowadays. I guess, if SILC
7157 is compiled with older va_arg() the new code should work anyway.
7159 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Splitted core library. Core library (lib/silccore) includes
7162 now only SILC protocol specific core (and common) components.
7163 Created new utility library (lib/silcutil) that includes more
7164 generic purpose stuff. The stuff for util library was taken
7165 from the old core library. This was minor and easy split.
7167 * Created SILC Client Library (lib/silcclient) that includes
7168 implementation of the SILC client without user interface. This
7169 was major move from silc/ directory. The code has been changed
7170 so that it is transparent towards the user interface. The
7171 silc/ directory includes now the same user interface as before
7172 and it uses the new client library. Read lib/silcclient/README.
7173 Basicly, the client library performs everything else related
7174 to SILC except user interface handling. Also, configuration
7175 files are considered to be part of user interface and library
7176 does not handle them.
7178 This change also changed a lot of structures, function naming etc.
7179 Most important change was that SilcClientWindow object was
7180 renamed to SilcClientConnection in the client library. Created
7181 also new file lib/silcclient/ops.h. Also added new files
7182 silc/local_command.[ch] and silc/client_ops.[ch].
7184 All these changes were made to make it easier for user interface
7185 designers to create what ever user interface for the SILC client
7188 It is also expected that the server will be moved to lib
7189 directory as well and SILC Server Library will be created;
7190 sometimes in the future.
7192 * Removed Local commands from lib/silccore/silccommand.h as
7193 they are application specific and new client library does not
7194 handle any of those anymore.
7196 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7197 old client implementation in silc/.
7199 * Added support for callback functions in SILC_LOG_* macros.
7200 Application can now set its own callbacks that will be called
7201 instead of using the default functions that will always print
7202 the debug messages to stderr (or stdout). Also, debugging can
7203 now be disabled by setting silc_debug to FALSE and re-enabled by
7204 setting it to TRUE. Note, that logging will still work even
7205 if debugging is disabled.
7207 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7208 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7209 silc_log_reset_debug_callbacks.
7211 * To enable debugging in silc client one must give now -d
7212 option on command line.
7214 * Changed silc_schedule_init to automatically allocate task queues
7215 if they are not allocated before calling it.
7217 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7219 * Added GMP 3.1 into math library.
7221 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7224 a channel in SILC network. The packet is used by servers and
7225 routers to notify other routers that user has left a channel.
7226 This little feature was missing until now. Added the feature
7227 to protocol specification as well.
7229 Added functions: silc_server_send_remove_channel_user and
7230 silc_server_remove_channel_user into server.[ch].
7232 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7233 lib/silccore/silcpacket.h. However, they are not implemented
7236 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Fixed joining to a channel and sending channel messages
7239 between server and router. The channel message sending should
7240 now work inside a cell.
7242 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * Fixed the private message sending between server and router.
7245 The private message sending should now work inside a cell.
7247 * Added silc_server_replace_id into server.[ch] to replace
7248 existing ID in the SILC network.
7250 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7251 and silc_idlist_replace_server_id into idlist.[ch] in server.
7253 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Fixed the server to server connections. Server can again now
7256 connect to router. Router to router connections probably does
7259 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Added dynamic protocol registering support. Now protocols can
7262 registered and unregistered on the fly. Patch by cras.
7264 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Added lib/contrib directory to hold routines that some platforms
7267 don't have but are needed by SILC.
7269 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7270 into lin/contrib to provide getopt() and getopt_long() for
7271 those who don't have it.
7273 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * Added AWAY command to client. When away message is set and
7276 client receives a private message packet the client automatically
7277 replies to the sender with the away message.
7279 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7280 bug seemed to be the cause of recent problems when compiling
7283 * Added version detection support to SKE protocol specification
7284 and added the new changes to the SKE implementation as well.
7285 There were other minor changes in the SKE protocol as well.
7287 Many changes in lib/silcske/silcske.[ch] and in
7288 lib/silcske/payload.[ch].
7290 * Added ^U functionality, clear input line. Patch from cras.
7292 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7294 * Mainly small bugfixes on core library. Fixed some debugging
7295 logging and buffer overflow in silclog.c.
7297 * Updated config.sub and config.guess on the distribution tree.
7299 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Added command lagging support in server. Client may execute
7302 commands now only once in two seconds.
7304 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7306 * Optimized packet reception. MAC computation and checking is now
7307 also more optimized. A lot previously duplicated code is now
7308 used as generic by both client and server.
7310 * Fixed key pair generation in clientutil.c
7312 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Added into lib/silccore/silcbufutil.[ch] new function;
7315 silc_buffer_realloc.
7317 * Moved generic packet sending/encryption functions to
7318 lib/silccore/silcpacket.[ch] from client and server. Some
7319 rewriting of the functions.
7321 * Moved all generic packet reception/decryption functions to
7322 lib/silccore/silcpacket.[ch] from client and server. The
7323 packet processing is now much cleaner in both client and server.
7324 These were major changes in both client and server.
7326 * Created many common functions in server to do packet sending.
7327 Previously code were duplicated a lot, this has been removed
7330 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Rewrote major parts of the ID cache system. Don't know
7333 whether it is better now or not but at least the API is more
7336 * Major rewrite on ID cache stuff on client because of the ID
7337 cache API changes. Added idlist.c to client.
7339 * Also major rewrite on ID cache stuff on server as well.
7340 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7341 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7342 in hand, instead they are all put into the ID cache system now.
7343 All server_idlist_* routines uses ID cache now instead of
7344 traversing its own lists (those lists does not exist anymore).
7345 SilcIDList though still exists. Also, SilcXXXEntry's are
7348 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Finally made the SKE implementation compliant to the protocol
7351 specification. All mp integers are now binary encoded as
7352 opposed being HEX encoded.
7354 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7357 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7358 functions: silc_[encode/decode]_pem. Also added function
7359 silc_encode_pem_file to PEM encode with newlines ('\n') for
7362 * SILC public keys are now encoded either PEM or binary. Same
7363 option is for private keys as well. By default private keys
7364 are binary encoded and public keys PEM encoded. Silly HEX
7365 encoding were removed.
7367 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7368 function to create fingerprints.
7370 * Fixed a bug in SHA1; does not change the original data anymore.
7372 * Partly implemented INFO command on client and server side.
7373 Fixed CLEAR command. Changes to SERVER command; show current
7374 server(s) when giving command without arguments. Added
7375 VERSION command to client.
7377 * Added check to server that unregistered connections cannot
7378 execute commands (unless it is specificly allowed).
7380 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Fixed screen refresh.
7384 * Fixed channel joining bug from client. On some circumstances
7385 client tried to join to a channel it had already joined.
7387 * Added public key verification process into client's protocol.c.
7388 The client now verifies the public key from user and saves
7389 it into ~./silc/serverkeys/ directory.
7391 Added into: clientutil.[ch]: silc_client_verify_server_key.
7393 * Changed SKE protocol's silc_ske_initiator_finish function
7394 to accept callback function that verifies the received public
7395 key. Removed old silc_ske_verify_public_key function.
7397 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7399 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7400 silc_pkcs_private_key[_data]_set.
7402 * Made the password and public authentication more cleaner in
7403 server's protocol.c.
7405 * Removed historic and obsolete protocol `channel_auth' from
7406 both client and server.
7408 * Removed wrong way of sending command status messages from
7409 server to client in server's command.c. The old way violated
7410 protocol specification.
7412 Changes to silccore/silccommand.[ch]: removed
7413 silc_command_encode_status_payload -> not needed anymore,
7414 changed silc_command_encode_payload_va to accept extra
7415 argument on variable argument list. The argument type must
7416 now be provided to the function. Also, added new function:
7417 silc_command_encode_reply_payload_va which is same as
7418 normal command_encode_payload_va except command status type
7419 is provided as extra argument.
7421 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7423 * Added ~./silc directory handling. The directory includes the
7424 public and private keys for the client.
7426 Added silc_client_check_silc_dir, silc_client_create_identifier
7427 and silc_client_load_keys.
7429 * Implemented SILC protocol compliant public key. Added public
7430 and private key saving to and loading from files.
7432 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7433 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7434 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7435 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7436 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7438 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7439 silc_pkcs_load_[public/private]_key.
7441 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Added silc_server_get_route (route.[ch]) to get connection
7444 data for the fastest route for given ID.
7446 * Implemented INVITE command on client and server. The command
7447 were re-defined in the SILC Protocol Specification and the
7448 implementation now complies with the specification.
7450 * Implemented PING command on client and server.
7452 * Implemented NAMES command on client and server. The server side
7453 supports currently only normal server not router server yet.
7454 Some changes to NAMES definition in SILC protocol specification.
7456 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Implemented LEAVE command on client and server.
7460 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7461 again. This change was made to the protocol as well. Server
7462 should not violate the protocol specification anymore.
7464 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7466 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7467 was tested. SOCKS4 was not but should work anyway.
