3 * Fixed a security problem found in SKE. The initiator's
4 public key too is now added to the HASH hash value creation
5 which is signed by the responder to create the SIGN value.
6 This will prevent anyone in the middle to lie to the responder
7 about the initiator's public key. If this is done now, the
8 man in the middle will get caught. Updated the protocol
11 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
13 * Better installation directory handling. Configure module
14 paths and other paths automatically to example_silc* files

64 * Fixed the silc_client_packet_parse to not to increase
65 the packet sequence number if the conn->sock and the
66 current socket connection is not same. This can happen
67 for example during key agreement when the conn includes
68 multiple socket connections (listeners). Affected file
69 lib/silcclient/client.c.
71 * The sender of the file transfer request now provides also
72 the pointer (listener) for the key exchange protocol. If
73 the listener cannot be created then it sends empty key
74 agreement and lets the receiver provide the listener.
76 Added `local_ip' and `local_port' arguments to the
77 silc_client_file_send. If they are provided they are used,
78 if not then it will attempt to find local IP address, if
79 not found or bind fails then the remote client will provide
82 Affected files are lib/silcclient/client_ftp.c and
83 lib/silcclient/silcapi.h.

92 of the client's public key (if the proof of posession of the
93 corresponding private key is verified by the server).
94 Updated to the protocol specification.
96 * Added support of receiving the client's public key's
97 fingerprint in command reply in client library. Affected
98 file is lib/silcclient/command_reply.c, and

157 during SERVER_SIGNOFF, but invalidate it. This way we
158 preserve the WHOWAS info for the client. Affected file
161 * Fixed SERVER_SIGNOFF notify handling in the server. The
162 server is now able to process incoming SERVER_SIGNOFF notify
163 for a server that it doesn't even know about. It will remove
164 the clients provided in the notify. Affected file
165 silcd/packet_receive.c.
167 * Check for partial packet in data queue after every packet that

202 now in server, to optimize packet processing. Affected file
205 * Include files are installed now only in Toolkit distribution
206 if make install is given. Affected files: all Makefile.am's.
208 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
210 * Assure that silc_client_notify_by_server_resolve does not
211 resolve the client information multiple times. If it cannot
212 be found by the first it cannot be found at all. Affected
213 file lib/silcclient/client_notify.c.
215 * Fixed WHOWAS command reply calling. Affected file
216 lib/silcclient/command_reply.c.
218 * Removed all references to silc_idlist_get_client from the
219 Irssi SILC client since that call is internal call used by
220 the library. The Irssi SILC client will use now client
221 retrieval functions found in silcapi.h.
223 * Fixed a bug in resolving nickname info before sending
224 private message. It used freed memory. Affected file
225 irssi/src/silc/core/silc-servers.c.
227 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

251 in packet queue that we are not able to process without first
252 processing packets before them. Affected file silcd/server,
253 lib/silcclient/client.c.
255 * SilcPacketParserCallback now returns TRUE or FALSE to indicate

348 The SILC packet header change makes it impossible to be
349 backwards compatible.
351 * Send the ENDING packet with timeout in the backup resuming
352 protocol. This is to assure that all routers has connected
353 to the primary router. Affected file silcd/server_backup.c.
355 * Changed the RNG to take the first IV from random data. It
356 used to take it from zero actually. Changed the RNG also

360 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
362 * Changed the SILC packet header to have the first two bytes
363 (the packet length) encrypted. Affected files aroung the
364 code tree, lib/silccore/silcpacket.[ch]. Removed the
365 SilcPacketCheckDecrypt callback. It is not needed anymore
366 since the silc_packet_receive_process will determine now
367 whether the packet is normal or special.

381 announced by backup router are added to the global list
382 automatically. Update hte server's socket to our primary
383 router also when backup router announces a server.
384 Affected file silcd/packet_receive.c.
386 * Do not update the client->router in the function
387 silc_server_udpate_clients_by_server if the client is on
388 global list. We might fail to find any specific server
389 for locally connected clients and local cell clients. They
390 should still use the `from' and not `to' as client->router.
391 This fixes backup router resuming protocol. Affected file
394 * Decrease channel statistics count only if the channel
395 deletion worked. Affected files are silcd/server.c and

435 Affected file silcd/packet_send.c.
437 * Changed the SFTP Filesystem interface. Changed the
438 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
439 the filesystem operation function. The SilcSFTPFilesystem
440 is now a context that is allocated by all filesystem allocation
441 functions and it already includes the operations structure
442 and filesystem specific context. It is given as argument
443 now to the silc_sftp_server_start. This made the interface
444 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
445 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
447 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
449 * Changed the backup router adding and getting interfaces
450 in the server. The router that will be replaced by the
451 specified backup router is now sent as argument. Affected

561 * Fixed channel user mode saving in client library. Affected
562 file lib/silcclient/command[_reply].c.
564 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Defined the file transfer to the SILC Protocol. Added
567 new packet type SILC_PACKET_FTP and defined File Transfer
568 Payload. The mandatory file transfer protocol is SFTP
569 (SSH File Transfer Protocol). Affected file in addition
570 of the internet draft is lib/silccore/silcpacket.h.
572 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
573 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
574 is used as part of backup router protocol when the primary
575 router of the cell is back online and wishes to resume
576 the position as primary router.
578 * Redefined the MAC generation keys in the protocol. The
579 same key is not used anymore in both direction. Both
580 direction will now use different keys for sending and
581 receiving. This fixes a potential security flaw. This
582 change causes incompatibilities in the protocol.
584 * Redefined also the MAC computation from the packet.
585 An packet sequence number is now added to the MAC
586 computation. This prevents possible replay attacks against
587 the protocol. This change too causes incompatibilities
590 Added `sequence' field to the SilcPacketContext to hold
591 the current sequence number for the packet.
593 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
595 * Added `created' field to the SilcIDListData in the file
596 silcd/idlist.h to indicate the time when the entry was
599 * Added `created' field to the SilcChannelEntry too. Affected
602 * Added `creation_time' aguments to all the announcement functions
603 in the server. If it is provided then only the entries that
604 was created after the provided time frame are actually
605 announced. Affected file silcd/server.[ch].
607 * The protocol says that the Channel ID's IP address must be
608 based on the router's IP address. Added check for this in
609 the silc_server_new_channel when processing incoming New Channel
610 Payload. Affected file silcd/packet_receive.c.
612 * Print out the correct version with --version in SILC client.
613 Affected file irssi/src/silc/core/silc-core.c.
615 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
617 * Fixed WHOWAS command to check for completnes of the client
618 entry always, not just when the command is coming from client.
619 Affected file silcd/command.c.
621 * Added new function silc_server_packet_queue_purge to purge the
622 outgoing data queue to the network. After the function returns
623 it is guaranteed that the outgoing packet queue is empty.
624 Affected file silcd/packet_send.[ch].
626 * Purge the outgoing packet queue in the rekey protocol's final
627 callback to assure that all rekey packets go to the network
628 before quitting the protocol. Affected file silcd/server.c.
630 * Added silc_client_packet_queue_parse as similar function as
631 in server to the client library. The affected file is
632 lib/silcclient/client.c.
634 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
636 * Splitted silcd/server.c and created silcd/server_util.[ch]
637 for utility functions.
639 * Added new socket flag SILC_SF_DISABLED to indicate that the
640 connection is open but nothing can be sent to or received from
641 the connection. Affected file lib/silcutil/silsockconn.[ch].
642 The checking for disabled socket is checked in the low level
643 silc_socket_write and silc_socket_read functions.
645 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
647 * Allow only nicknames and channel names that fits into the
648 7-bit unsigned char ASCII set. Affected file silcd/command.c.
650 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
652 * When processing JOIN command reply in server check that if
653 the channel exists in our global list we'll move it the local
654 list. Affected file silcd/command_reply.c.
656 * Fixed the check whether client is joined on the channel already
657 in JOIN command. Affected file lib/silcclient/command.c.
659 * Fixed the JOIN command reply to check whether the channel
660 already exists. Affected file lib/silcclient/command_reply.c.
662 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
664 * Added silc_ske_status_string to map the SKE error numbers
665 to readable strings. The affected files are
666 lib/silcske/silcske[_status].[ch].
668 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
670 * Do not show the private channels on the WHOIS channel list
671 as it is not allowed by the protocol. The affected file is
674 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
676 * Assure that the packet length digged from the actual packet
677 is something sensible in the silc_packet_decrypt_rest_special
678 in lib/silccrypt/silcpacket.c.
680 * Free and NULL the allocated pointer in silc_hmac_alloc if
681 the HMAC allocation fails. The affected file is
682 lib/silccrypt/silchmac.c.
684 * Print the selected security properties to the log files in
685 the server. Affected file silcd/protocol.c.
687 * Add SKE's reference counter even if calling the completion
688 callback manually. Otherwise it goes negative, although it
689 does not cause any problems. The affected file is
690 lib/silcske/silcske.c.
692 * Remove the client entry with short timeout after giving the
693 KILL command. Affected file lib/silcclient/command.c.
695 * Fixed to send error reply in WHOIS and IDENTIFY commands in
696 case all found clients are already disconnected (WHOWAS would
697 found them) in the server. Affected file silcd/command.c.
699 * Update the last_receive (time of last data received) to be
700 updated only when received private or channel message so that
701 the idle time showed in WHOIS makes more sense.
703 * Added boolean field `valid' in to the SilcClientEntry in the
704 client library to indicate whether the entry is valid or not.
705 This fixes the nickname change bug on channel when changing
706 the nickname to be same than the old (like nick to Nick) the
707 nickname formatter doesn't set the new nick anymore to Nick@host.
708 Affected file lib/silcclient/idlist.[ch].
710 * Now actually fixed the nickname changing on disconnection.
711 Added new function silc_change_nick to the Irssi SILC Client.
712 Affected file irssi/src/silc/core/client_ops.c,
713 irssi/src/silc/core/silc-nicklist.[ch].
715 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
717 * Check that the public key exists in the GETKEY command before
718 trying to encode it. Affected file silcd/command.c.
720 * Print some notifications on received public keys with GETKEY
721 command in the Irssi SILC Client. Affected files are
722 irssi/src/fe-common/silc/module-formats.[ch],
723 irssi/src/silc/core/client_ops.c.
725 * Use IDENTIFY command to resolve the server information in the
726 GETKEY command instead of INFO command. Affected file
727 lib/silcclient/command.c.
729 * All command reply functions in the client library now calls
730 the pending command reply callbacks even if an error has
731 occurred. The server has done this a long time and now it was
732 time to move the client library to this as well. Now all
733 errors can be delivered back to the pending command reply
734 callbacks if necessary. Affected files are
735 lib/silcclient/command[_reply].[ch].
737 * Change the nickname on disconnection back to the username
738 because in reconnect the server will enforce it to it anyway.
739 Affected file irssi/src/silc/core/silc-servers.c.
741 * Fixed a config file parsing bug in the Irssi SILC client.
742 Affected file irssi/src/silc/core/clientconfig.c.
744 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * When printing the channel mode on JOIN, verify that the
747 channel key and channel's HMAC are valid. Affected file
748 irssi/src/silc/core/client_ops.c.
750 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
753 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
754 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
756 * Removed channel key rekey task deleting from the function
757 silc_server_save_channel_key. Affected file silcd/server.c.
758 Added explicit timeout task context instead that is used to
759 delete the task if we are registering a new task before the
760 new task has elapsed.
762 * When channel key rekey occurs the client library now saves
763 the old channel key for a short period of time (10 seconds) and
764 is able to use it in case some is still sending channel
765 messages encrypted with the old key after the rekey. Affected
766 file lib/silcclient/[idlist.h|client_channel.c].
768 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Added check to the silc_server_new_id_real to not accept
771 new ID if it is the sender's own ID. Affected file is
772 silcd/packet_receive.c.
774 * Assure that we do not announce ourself or the one we've
775 sending our announcements when we're router and are announcing
776 servers to our primary router. Affected file silcd/server.c.
778 * Fixed silc_server_command_identify_check_client to assemble
779 correct WHOIS packet. It send corrupted WHOIS packet and
780 caused problem with router to router connections. Affected
781 file silcd/command.c.
783 Fixed also silc_server_command_whois_check the same way
784 as for the IDENTIFY command.
786 * Added new SilcIDListStatus to the server in the SilcIDListData
787 structure. The status now includes the current status of
788 the entry (like registered, resolved etc.). Affected file
789 silcd/idlist.[ch]. Defined a bunch of different status types
790 as well. This replaced the old boolean registered field as well.
792 Added resolve_cmd_ident field to the SilcClientEntry structure
793 too so that if the entry is for example being resolved so
794 another command may attach to the same pending command reply
795 without requiring to resolve the same entry again. This concept
796 should optimize the WHOIS and the IDENTIFY resolving under
797 heavy load by taking away unnecessary resolving for entries
798 that are being resolved already.
800 Added support for adding multiple pending commands for one
801 command idenfier. Affected file silcd/command[_reply].[ch].
803 * Fixed WHOIS and IDENTIFY save to remove the cache entry
804 before deleting the data. Otherwise the hash table will have
805 freed data in comparison functions. Affected file is
806 silcd/command_reply.c.
808 * Fixed silc_idlist_replace_client_id to add the new entry to
809 the cache with NULL nickname. Otherwise there will be invalid
810 memory as the nickname after the nickname is freed. Affected
811 file silcd/packet_receive.c.
813 * Fixed the silc_idlist_get_clients_by_hash. The entries was
814 saved into wrong slots because the previous number of entries
815 was not taken into account. Affected file silcd/idlist.c.
816 Fixed same thing in silc_idlist_get_clients_by_nickname too.
818 * If we are router and we receive JOIN notify to a channel that
819 does not have any users then notified client is marked as the
820 channel founder, as it is it. The affected file is
821 silcd/packet_receive.c
823 * Added to the extended hash table API's table_del_*ext functions
824 the destructor as argument too, so that the caller can decide
825 which destructor to use or whether to use destructor at all.
826 Affected file lib/silcutil/silchashtable.[ch].
828 * Fixed ID Cache purging. It actually deleted the entries from
829 the hash table after the data was freed. The hash table ended
830 up comparing freed memory. The affected file is
831 lib/silccore/silcidcache.c.
833 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
835 * Fixed Irssi SILC client's KILL command's HELP syntax.
837 * The USERS command now resolves the detailed user information
838 if the userinfo field is missing. Affected file is
839 lib/silcclient/command_reply.c.
841 * Do not print error in silc_file_read if the read file does
842 not exist. Just silently return NULL. Affected file is
843 lib/silcutil/silcutil.c.
845 * Fixed the silc_log_output to not wine about NULL filename
846 and to not create some bogus " " filename. Affected file is
847 lib/silcutil/silclog.c.
849 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Fixed various printing bugs on the user interface in the
852 Irssi SILC Client. Minor changes that were forgotten from
855 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Fixed the configure.in.pre and the compilation and distribution
858 environment to support the new autoconf 2.52. That version is
859 now required to compile the CVS trunk.
861 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
863 * Renamed function silc_parse_nickname to silc_parse_userfqdn
864 to generally parse user@fqdn format strings. Affected file
865 lib/silcutil/silcutil.c.
867 * Added nickname_format and nickname_force_format fields to the
868 SilcClientParams structure. The first one defines the format
869 for the nicknames that the library will enforce if the receives
870 multiple same nicknames. The second one is boolean value and
871 can be used to force the library to always enforce the format
872 to the nicknames regardles whether there are multiple nicknames
873 or not. This configurable formatting was employed to flexibly
874 support accessing multiple nicknames from the user interface.
875 The userinterface can now set the nicknames to what ever format
876 they prefer. Affected file lib/silcclient/silcapi.h.
878 Added function silc_client_nickname_format to the file
879 lib/silcclient/idlist.c. It performs the nickname formatting.
881 Added new field `hostname´ to the SilcClientEntry context.
882 It holds the hostname of the client. Affected file is
883 lib/silcclient/idlist.h.
885 * Irssi SILC Client sets the nicknames in nick@hostn format.
886 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
887 irssi/src/silc/core/silc-core.c.
889 The WHOIS printing now also shows both the real nickname and
890 the formatted nickname so that user knows how to access the
891 user if there are multiple same nicknames cached. Affected
892 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
893 printing formatting too to take the hostname now as a separate
894 argument. The Affected file is
895 irssi/src/fe-common/silc/modules-formats.[ch].
897 * Changed the silc_client_get_clients_local to accept the formatted
898 nickname as argument. It accepts the real nickname too but the
899 formatted nickname can be used to find the true entry from
900 multiple entries. Affected file lib/silcclient/silcapi.h and
901 lib/silcclient/idlist.c.
903 * Added nickname_format_parse field to the SilcClientParams.
904 It is a callback function provided by the application to parse
905 the nickname out of the formatted nickname string. The library
906 calls it to get the nickname from the formatted string. Since
907 the application generally knows better the format of the nickname
908 string it parses it instead of the library, even though library
909 encodes the formatted string. If the callback function is not
910 provided then the library will use the string as is. The
911 affected file is lib/silcclient/silcapi.h.
913 * All the nickname strings passed to the client library in
914 commands are now expected to be formatted nickname strings.
915 If the command does not support the formatted nickname string
916 it will assume that the sent string is the actual nickname.
917 Affected file lib/silcclient/command.c.
919 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Added public key authentication support to OPER and SILCOPER
922 commands in the client library. Affected file is
923 lib/silcclient/command.c.
925 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
927 * Changed the get_auth_methdod client operation to be asynchronous.
928 It can be async if the application resolves the authentication
929 method from the server during the negotiation. Added new
930 SilcGetAuthMeth completion callback that the application will
931 call after resolving the authentication method.
933 Added function silc_client_request_authentication_method that
934 the application can use to resolve the authentication method
935 from the server. Added also SilcConnectionAuthRequest callback
936 that the library will call after the server has replied. The
937 application can call this function if it does not know the
938 current authentication method.
940 Affected files are lib/silcclient/client.c and
941 lib/silcclient/silcapi.h.
943 * The Irssi SILC client now automatically resolves the authentication
944 method incase any configuration information is not present (and
945 currently there never is). The affected file is
946 irssi/src/silc/core/client_ops.c.
948 * Fixed public key authentication from the client library.
949 Affected file lib/silcclient/protocol.c. Changed also the
950 protocol specification about the public key authentication in
951 the connection authentication protocol. The actual data to be
952 signed is now computed with a hash function before signing.
954 * Fixed the public key authentication from the server as well.
955 Affected file silcd/protocol.c.
957 * Removed the mlock()'s from the memory allocation routines.
958 Affected file lib/silcutil/silcmemory.c. The ./configure does
959 not check anymore for the mlock(). Affected file is
962 * Fixed USERS command in server to allow the execution of the
963 command for private and secret channels if the client sending
964 the command is on the channel. Affected file silcd/command.c.
966 * Fixed silc_client_get_clients_local to return the clients
967 count correctly. It could return wrong value. Affected file
968 lib/silcclient/idlist.c.
970 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
972 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
973 types. The assembler optimizations seemed not to like 64-bit
974 data types. The assmebler optimizations thus are now enabled
975 also for BSD systems as opposed to only enable them for Linux.
977 * Do not check for threads at all on BSD systems. Affected
978 file configure.in.pre.
980 * Removed -n and -h options from the Irssi SILC Client since
981 they are not used in silc.
983 * Fixed the prime generation to assure that the first digit
984 of the generated random number is not zero since our conversion
985 routines does not like number strings that starts with zero
986 digit. If zero digit is seen the random number is regenerated.
987 This caused some corrupted RSA keys when the zero first digit
988 was met. Affected file lib/silcmath/silcprimegen.c.
990 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Fixed WIN32 configuration in the ./configure script.
993 Fixed to include xti.h on environments that has it.
994 Patches by Carsten Ilchmann and andrew.
996 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
998 * Changed the silc_id_create_client_id to be collision
999 resistant. It is now assured that there cannot be created
1000 two same client ID's. I suspect that some weird bugs in
1001 the server were actually caused by duplicate Client IDs.
1002 Affected file silcd/serverid.[ch]. A router receiving
1003 new ID now also assures and informs the sending server
1004 if the ID caused collision.
1006 * Changed the silc_id_create_channel_id to also assure that
1007 there are no collisions.
1009 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1011 * Statement about ignoring the Mutual Authentication flag when
1012 performing rekey with PFS was a bit misleading. It is ignored
1013 if it was set in the initial negotiation, it cannot be even
1014 set in the rekey. Fixed in the ke-auth draft. Started the
1015 new versions of the protocol drafts in the doc/.
1017 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1019 * Fixed a bug in silc_client_command_identify_save when saving
1020 new channel information. The channel name was no duplicated
1021 and caused crash on exit. Affected file is
1022 lib/silcclient/command_reply.c.
1024 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Fixed the getkey command handling in the server. Send just
1027 empty OK reply to the sender if the key could not be fetched
1028 (but everything else was ok, like the key just was not available).
1029 Changed the public key parameter to optional in the protocol
1030 specs so that empty OK reply can be sent. Affected file
1033 Added a message to Irssi SILC client to tell to user if the
1034 server did not return a public key.
1036 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1038 * Fixed a channel key regeneration bug. It registered new
1039 timeout tasks exponentially until all system resources were
1040 used. Affected file silcd/server.c.
1042 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Added the SILC Document generator to the scripts/silcdoc.
1045 It can be used to generate the Toolkit Reference Manual out
1046 of the source tree. Internally it will also use the RoboDoc
1047 generator now imported in util/robodoc.
1049 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Added couple of return's in rekey protocol if error orccurred
1052 during the protocol. The execution must be terminated.
1053 Affected file silcd/protocol.c. Also, terminate the protocol
1054 always with timeout.
1056 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * The client's Client ID was created initally from the wrong
1059 nickname (it could have been in format nick@host) in the
1060 silc_server_new_client. Affected file silcd/packet_receive.c
1062 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Added some SILC_LOG_ERROR's to various error conditions
1065 if client could not be added to ID cache. Affected files
1066 silcd/packet_receive.c and silcd/server.c.
1068 * When client's sock->user_data is freed, NULL also the
1069 client->router and client->connection pointers. Added check
1070 for these pointers being NULL to various places around the
1071 code. Affected file silcd/server.c.
1073 * Added client->data.registered == TRUE checks to various
1074 places around the code to assure that unregistered client's
1075 are not handled when it is not allowed. Affected file
1078 * Added `bool registered' fields to all
1079 silc_idlist_[server|client]_get_* routines to indicate whether
1080 the fetched client needs to be registered or not. Affected
1081 file silcd/idlist.[ch].
1083 * Add your own entry as registered to the ID cache in the
1084 server. Affected file server.c.
1086 * Fixed a bug in silc_server_new_server. The SilcServer was
1087 set as the new server's context instead of SilcServerEntry.
1088 This naturally caused some weird bugs.
1090 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Do not delete the channel rekey task when adding it
1093 for in silc_server_create_channel_key.
1095 * Changed the silc_server_create_channel_key to return
1096 TRUE or FALSE to indicate the success of the channel key
1099 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Fixed MSVC++ project files and added missing files to

1106 * Do not add TCP_NODELAY flag if the operating system
1107 does not have it defined. Affected files are
1108 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1110 * Fixed buffer overflow from Irssi SILC Client. Affected
1111 file irssi/src/fe-common/core/themes.c.
1113 * Fixed double free in client library in the file
1114 lib/silcclient/client.c when disconnecting from server.
1116 * Applied double free patch from cras to Irssi SILC client.
1117 Affected files irssi/src/core/[modules/expandos].c
1119 * Fixed the disconnection handling to Irssi SILC Client.
1120 The application must call silc_client_close_connection
1121 in ops->connect client operation in case of failure of
1122 the connection. Affected file is
1123 irssi/src/silc/core/client_ops.c.
1125 * Do not set sock->protocol to NULL in the function
1126 silc_client_close_connection after executing the protocol's
1127 final callback since the sock might not be valid anymore.
1128 Affected file lib/silcclient/client.c.
1130 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * Do not enable SILC_THREADS if the linking with libpthread
1133 did not happen. Affected file configure.in.pre.
1135 * Added notion to protocol specification that server must
1136 verify the sent authentication payload with CMODE when
1137 setting the channel founder key. Implemented it to the
1138 server. Affected file silcd/command.c.
1140 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Added _EXTRA_DIST SILC distribution variable to the
1143 distributions file. It is used to conditionally add extra
1144 files or directories to the specific distribution. Affected
1145 files ./prepare, Makefile.am.pre and distributions.

1150 * Added README.WIN32 for instructions to compile the Toolkit
1153 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Fixed a double free in disconnection in the server. Affected
1156 file is silcd/server.c.
1158 * Fixed the lib/silcske/groups.c to work now also with GMP
1159 MP library. The string conversion did not work when using
1160 specific base and the base is indicated in the string as well.
1162 * Created win32/ directory which now includes MSVC++ specific
1163 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1164 It will appear only in the toolkit distribution
1166 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Changed the key material distribution function in case when
1169 the hash output is too short. The data is now concatenated
1170 a bit differently than it used to. Made the change to the
1171 SKE protocol specification.
1173 * Added better GMP detection to configure.in.pre. A patch
1176 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Fixed a minor bug in SKE that might cause some problem on
1179 some platforms. Affected file lib/silcske/silcske.c.
1181 * Added the cookie checking for initiator in the SKE. It checks
1182 that the responder returns the sent cookie unmodified. The
1183 affected file is lib/silcske/silcske.c. Added new SKE
1184 error type INVALID_COOKIE that can be sent during the
1185 negotiation. Fixed some memory leaks as well.
1187 * Added the "invalid cookie" error message to Irssi SILC client's
1190 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Added `task_max' field to the SilcClientParams to indicate
1193 the maximum tasks the scheduler can handle. If set to zero,
1194 default values are used. Affected file lib/silcclient/silcapi.h.
1196 * Fixed memory leaks in silc_client_close_connection. Affected
1197 file lib/silcclient/client.c.
1199 * Added silc_client_del_client_entry to client library to free
1200 all memory of given client entry. Affected file is
1201 lib/silcclient/idlist.[ch].
1203 * Added new functions silc_client_del_channel and
1204 silc_client_del_server to delete channel and server entries.
1205 Affected file lib/silcclient/[silcapi.h/idlist.c].
1207 * Removed silc_client_del_client_by_id from silcapi.h.
1209 * Fixed the INFO command to return the server's own info
1210 correctly when querying by Server ID. Affected file is
1213 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Removed the non-blocking settings in WIN32 code in the
1216 silc_sock_[read/write] and added SleepEx instead. Affected
1217 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1218 of input data is now checked with FIONREAD and ioctlsocket.
1220 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Call silc_schedule_task_del_by_context in the
1223 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1224 Affected file lib/silccore/silcprotocol.c.
1226 * Call silc_protocol_cancel for active protocols in the
1227 silc_server_close_connection if the funtion
1228 silc_server_free_sock_user_data has not been called.
1229 Affected file silcd/server.c.
1231 * Generic tasks cannot be deleted using the del_by_fd
1232 task deleting function since generic tasks does not match
1233 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1235 * Added a notion to SILCOPER help file that the SILCOPER works
1236 only on router server, not on normal server.
1238 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Added for WIN32 support for the new scheduler as well.
1241 Affected file lib/silcutil/win32/silcwin32schedule.c.
1243 * Fixed the SHA1 implementation to work on various platforms.
1245 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1248 API. It is part of the scheduler now. Everything else is
1249 as previously but some functions has changed their names.
1250 Checkout the lib/silcutil/silcschedule.h for the interface.
1251 Updated all applications to use the new interface. Affected
1252 files are lib/silcutil/silcschedule.[ch].
1254 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1256 * Found a bug in the SKE implementation. The HASH value,
1257 specified by the protocol, was not computed correctly. The
1258 public key of the responder was not added to the computation
1259 even though it is mandatory. Affected file lib/silcske/silcske.c.
1260 This unfortunately causes incompatibilities with older
1261 clients and servers.
1263 * Added WIN32 specific network init and uninit functions:
1264 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1265 the Winsock2. Affected file lib/silcutil/silcnet.h and
1266 lib/silcutil/win32/silcwin32net.c.
1268 * Set the socket always to nonblocking mode on WIN32 after
1269 reading data or writing data. Affected file is
1270 lib/silcutil/win32/silcwin32sockconn.c.
1272 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1274 * Fixed various compilation problems under WIN32. Affected
1275 files lib/silcutil/win32/silcwin32thread.c and
1276 lib/silcutil/win32/silcwin32schedule.c.
1278 * Removed all _internal.h #includes from public header
1279 files. Internal headers must never be included from
1282 Removed also the lib/silcske/payload_internal.h file.
1284 * All include files that may be needed (public and some others
1285 included by the public headers) by application developers are
1286 now copied to the ./includes directory. It does not copy any
1287 internal headers. Affected file Makefile.defines.pre and all
1288 Makefile.am's under lib/ and subdirs.
1290 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1292 * Do not change the ~/.silc directory's permissions automatically.
1293 Affected file irssi/src/silc/core/clientutil.c.
1295 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1297 * Do not cancel the protocol in silc_server_close_connection
1298 it might cause recursion. Now cancelled in the function
1299 silc_server_free_sock_user_data. Affected file silcd/server.c.
1301 * Fixed the silc_server_remove_clients_by_server to regenerate
1302 the channel keys correctly finally. Added also new function
1303 silc_server_remove_clients_channels to actually do it.
1304 Affected file silcd/server.c.
1306 * Fixed the silc_server_new_channel to not crash by giving
1307 wrong router to the new channel. Affected file is
1308 silcd/packet_receive.c.
1310 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1313 which is given as argument to the silc_client_alloc now.
1314 It can be used to configure the client and set various parameters
1315 that affect the function of the client.
1317 * The USERS command in server did not check whether the channel
1318 is private or secret. Affected file silcd/command.c.
1320 * Added new argument to the USERS command in protocol specification.
1321 The USERS command now can take the channel name as argument
1322 as well. Added support for this in client and server and
1323 updated the protocol specs.
1325 * Completed the GETKEY command in client. It can be now used
1326 to fetch also servers public key not only some clients.
1327 Affected files lib/silcclient/command[_reply].c.
1329 * Added silc_client_get_server to return server entry by the
1330 server name. Affected files lib/silcclient/silcapi.h and
1333 * Redefined the IDENTIFY command in protocol specification to be
1334 more generic. It now can be used to query information about
1335 any entity in the SILC Network, including clients, servers and
1336 channels. The query may be based either the entity's name
1337 or the ID. Added support for this in both client and server.
1339 Affected files silcd/command.c and lib/silcclient/command.c
1340 and command_reply.c.
1342 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1343 the _from_client and _from_server functions. Affected file
1346 * Added silc_client_get_channel_by_id_resolve to the file
1347 lib/silcclient/silcapi.h to resolve channel information by
1348 its ID. Added also silc_client_get_channel_by_id that
1349 does not resolve it from the server.
1351 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1353 * Added SilcServerEntry context into the client library
1354 to represent one server. The INFO command now allocates
1355 these to save the resolved server info. For now on the
1356 client library will also keep information about servers,
1357 connected and resolved with INFO.
1359 The INFO command now allocates the SilcServerEntry context
1360 and saves the server info there. The COMMAND_REPLY in
1361 the INFO now returns the parameters to application in
1362 same order as defined in the protocol specification.
1364 The entries are cached in the client->server_cache.
1366 * The INFO command is now issued after received the Client ID
1367 from the server. Affected file lib/silcclient/client.c.
1369 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1370 to the application as the mode changer might be server.
1371 It is guaranteed that NULL is not returned anymore to the
1372 application. Affected file lib/silcclient/client_notify.c.
1374 The ID Type is now also passed to the application so that
1375 it can check whether the returned entry is SilcClientEntry
1378 Added new function silc_client_get_server_by_id to return
1379 the server entry by ID. Affected files are the
1380 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1382 * Do not create the channel in the Irssi SILC Client when issuing
1383 the JOIN command but when received the sucessful JOIN command
1384 reply. Otherwise the channel might get created even though we
1385 could not join it. The Affected file is
1386 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1388 * Fixed a channel joining bug in router. The router must also
1389 check the channel modes, invite and ban lists etc. when serving
1390 the JOIN command sent by normal server. Affected file is
1391 silcd/command.c. The router now resolves the client's
1392 information from the server who sent the JOIN command if it
1393 does not know it, and processes the JOIN command only after
1396 * Changed the SilcCommandCb to take new argument; void *context2.
1397 Affected file lib/silccore/silccommand.h
1399 The second argument in the command callbacks in the server now
1400 includes the SilcServerCommandReplyContext if the command was
1401 called as pending command callback from the command reply.
1402 Otherwise it is NULL. When called as pending the status of the
1403 command reply will be checked and if it was erronous the
1404 error will be sent to the original sender of the command.
1405 This way the client always receives the error messages even
1406 though the server was actually the one who received the error
1407 when it resent the command to router, for example. Affected
1408 files silcd/command[_reply].[ch].
1410 * Fixed sending WHOWAS command's error message to client if
1411 the requested client could not be found. It was missing.
1414 * Changed the CMODE and CUMODE commands reply arguments in the
1415 protocol specification. The Channel ID is now sent in both
1416 of the commands to identify the channel. Implemented this
1417 new feature to the client and server. Affected files
1418 lib/silcclient/command_reply.c and silcd/command.c.
1420 * Made better checks for invite and ban lists in the JOIN
1421 command in server. Affected file silcd/command.c.
1423 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * The server now performs the incoming host IP/DNS lookup
1426 using the silc_socket_host_lookup and thus does not block
1427 the server anymore. Affected file silcd/server.c.
1429 * Completed the multi-thread support for SILC Scheduler in
1430 the lib/silcutil/silcschedule.c.
1432 * Fixed the configure.in.pre to detect the pthread correctly
1435 * Fixed a deadlock in silc_task_queue_wakeup in the file
1436 lib/silcutil/silctask.c.
1438 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Added new function silc_schedule_wakeup that is used in
1441 multi-threaded environment to wakeup the main thread's
1442 schduler. It needs to be used when a thread adds a new task
1443 or removes a task from task queues. After waking up, the
1444 scheduler will detect the task queue changes. If threads
1445 support is not compiled in this function has no effect.
1446 Implemented the wakeup mechanism to both Unix and WIN32
1447 systems. Affected files are lib/silcutil/silcschedule.[ch],
1448 lib/silcutil/unix/silcunixschedule.c and the
1449 lib/silcutil/win32/silcwin32schedule.c.
1451 * Added new function silc_task_queue_wakeup to wakeup the
1452 scheduler by the specified task queue. Affected file
1453 lib/silcutil/silctask.[ch].
1455 * The silc_socket_host_lookup_start now wakes up the scheduler
1456 after adding the timeout task. Affected file is
1457 lib/silcutil/silcsockconn.c.
1459 * The silc_socket_host_lookup is synchronous now if the threads
1460 support is not compiled in. However, the callback is still
1461 called asyncronously through the scheduler, anyway. Affected
1462 file lib/silcutil/silcsockconn.c.
1464 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Added new function silc_socket_host_lookup to perform
1467 asynchronous IP and FQDN lookups for the socket connection.
1468 Affected files lib/silcutil/silcsockconn.[ch].
1470 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1473 that may or may not compile the mutex support in.
1475 Changed the silc_mutex_alloc interface. It allocates the
1476 mutex now to the sent pointer and returns TRUE or FALSE.
1478 Affected file lib/silcutil/silcmutex.h.
1480 * Wrote the SILC Task Queue interface to support multi-threads.
1481 Affected file lib/silcutil/silctask.[ch].
1483 * Wrote the SILC Scheduler to support multi-threads. Affected
1484 file lib/silcutil/silcschedule.c.
1486 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1489 in lib/silcutil/win32/.
1491 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Defined SILC Mutex API and SILC Thread API and implemented
1494 them for Unix. Affected files are
1495 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1496 lib/silcutil/unix/silcunixmutex.c and
1497 lib/silcutil/unix/silcunixthread.c.
1499 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1501 * Fixed the silc_server_remove_clients_by_server's channel
1502 key re-generation. The hash table handling was incorrect
1503 and would not work with many channels. Affected file is
1506 * Fixed some memory leaks around the server code.
1508 * Rewrote the silc_server_get_users_on_channel to support IPv6
1509 based Client ID's. Affected file silcd/server.c.
1511 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1512 specification. However, a separate document must be written
1513 to define the detailed signing procedure and the payload
1514 associated with the flag. Defined the flag to the
1515 lib/silccore/silcchannel.h as well.
1517 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Changed the dynamic tables to static size tables in the
1520 lib/silccrypt/silchmac.c.
1522 * Removed GCC dependencies from the code. A patch by cras.
1524 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Do not show the error "Error receiving packet bla bla"
1527 in server if it really was not an error (-2 means that reading
1528 is pending). Affected file silcd/server.c.
1530 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Fixed a possible crash in silc_server_remove_clients_by_server
1533 in silcd/server.c. Fixed there also some memory leaks.
1535 * Fixed the silc_idlist_replace_client_id. It could replace
1536 wrong key in the hash table. Affected file silcd/idlist.c.
1538 * Do not check whether there are global users on the channel
1539 if the channel->global_users is FALSE. Affected functions
1540 silc_server_remove_from_one_channel and
1541 silc_server_remove_from_channels in silcd/server.c. Also,
1542 do not check if the removed client is local as we can be
1543 sure that global client was not removed from the channel
1544 and checking for global users is not needed.
1546 * The silc_server_remove_clients_by_server now re-generates
1547 the channel keys correctly for those channels that had
1548 clients removed from them. Affected file silcd/server.c.
1550 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Found the reason of random crashes in the server. We weren't
1553 ignoring the SIGPIPE signal (which can be sent in write())
1554 and it crashed the server. Affected file silcd/silcd.c.
1556 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1558 * Assure that sock->user_data is not NULL in the function
1559 silc_server_packet_send in silcd/packet_send.c.
1561 * Disconnect the remote connection if it could not be added
1562 to any ID lists in the server. The affected file is
1565 * Check in silc_server_packet_send[_real/dest] that the
1566 socket is not disconnecting and ignore the data if it is.
1567 Affected file silcd/packet_send.c.
1569 * Define inline to __inline on native WIN32 compilation.
1570 Affected file includes/silcwin32.h.
1572 * Added some explicit type casts for inline code since MSVC
1573 require them. Affected files lib/silcutil/silcbuffer.h,
1574 lib/trq/silcdlist.h and lib/trq/silclist.h.
1576 * Print warning in log files from now on if the packet
1577 decryption fails. Affected file silcd/server.c.
1579 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Changed the `say' client operation's interface to accept
1582 new `type' argument to indicate the type of the message sent
1583 by the library. The application may filter the library's
1584 messages according the type. The affected file is the
1585 lib/silcclient/silcapi.h.
1587 * Added two new functions to lib/silcclient/silcapi.h:
1588 silc_client_del_client and silc_client_del_client_by_id.
1589 Affected file lib/silcclient/idlist.c.
1591 * Moved the clientincludes.h from includes/ to silc/ and
1592 serverincludes.h from includes/ to silcd/.
1594 * The modes for the CMODE and CUMODE are now passed as
1595 uint32 for application with COMMAND_REPLY. The affected
1596 file is lib/silcclient/command_reply.c.
1598 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * /WHOIS without arguments shows client's own information.
1601 Affected file lib/silcclient/command.c.
1603 * Changed PING to not accept any arguments. The specs
1604 says that client can ping only the connected server so
1605 requiring an argument is not needed. Affected file is
1606 lib/silcclient/command.c.
1608 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1610 * Fixed a fatal bug in private message sending and reception
1611 encryption and decryption when using private message keys.
1612 The implementation was incorrect and did not follow the
1613 specification. It causd that some of the message were
1614 lost since it did not use the sending and receiving keys
1615 as the protocol suggests. This has been fixed and will cause
1616 incompatibilities with older clients when sending private
1617 message encrypted with private message keys. Affected files
1618 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1619 and various other in Irssi SILC Client.
1621 Added `responder' boolean argument to the functions
1622 silc_client_add_private_message_key[_ske] to indicate when
1623 the key is added as responder or initiator of the key
1626 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Removed the silc_ske_check_version function and created
1629 a SilcSKECheckVersion callback. Added also a function
1630 silc_ske_set_callbacks that is now used to set all SKE
1631 callbacks. The callback functions are not given to
1632 the SKE functions anymore, but this function is used to
1635 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1637 * Added `silc_version' argument to the silc_client_alloc
1638 to define the version of the application for the library.
1639 The library will use the version string to compare it
1640 against the remote host's (usually a server) version
1641 string. Affected file lib/silcclient/silcapi.h
1643 * Added the KE protocol context to Key Agreement context
1644 in client library so that we can abort the SKE if it
1645 is in process when we get timeout. Affected file is
1646 lib/silcclient/client_keyagr.c.
1648 * Do not resolve the client ID forever if it returns in the
1649 first time that such client does not exist. This was done
1650 for example with private message. Affected file is
1651 lib/silcclient/client_prvmsg.c.
1653 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Do not add regex.h for WIN32. The affected file
1656 includes/silcincludes.h.
1658 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1659 not work yet 100%. It generates the DLL's automatically
1660 when compiling with --with-win32 under cygwin.
1662 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * lib/contrib/regex.c is not compiled on WIN32.
1666 * Added silc_net_get_socket_opt function to the
1667 lib/silcutil/silcnet.h.
1669 * Added includes/silcwin32.h for WIN32 specific includes
1672 * Do not use ptime structure or any of the posix process
1673 functions on WIN32 in lib/silccrypt/silrng.c.
1675 * Added silc_gettimeofday to provide generic function
1676 for struct timeval on all platforms. Added the function
1677 to lib/silcutil/silcutil.h.
1679 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1682 library as they clearly belong there. As a plus side we
1683 can make the actual socket connection routines platform
1686 Added also new generic function silc_socket_read and
1687 silc_socket_write (that used to be silc_packet_[read/write].
1688 The implementation of these are platform specific.
1690 * Added WIN32 specific routines of silc_socket_[read/write]
1691 to lib/silcutil/win32/silcwin32sockconn.c.
1693 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Added preliminary support for native WIN32 compilation under
1696 cygwin (using the -mno-cygwin option for GCC) to the
1697 ./configure.in.pre. The --with-win32 now prepares the
1698 compilation for native WIN32.
1700 * Rewrote the SILC Scheduler interface in the file
1701 lib/silcutil/silcschedule.h. The scheduler is now context
1702 based and does not have anymore any global static scheduler.
1703 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1704 and created lib/silcutil/win32 directory for WIN32 based
1707 * Added Unix specific network routines to the
1708 lib/silcutil/unix/silcunixnet.c and the old
1709 lib/silcutil/silcnet.c includes now only generic routines.
1711 Added WIN32 specific network routines to the
1712 lib/silcutil/win32/silcwin32net.c.
1714 * Added Unix specific utility functions from the
1715 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1717 * Added WIN32 SILC Scheduler to the file
1718 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1721 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * Do not handle JOIN notify in the server if the target client
1724 is not registered (idata->registered == FALSE). The affected
1725 file is silcd/packet_receive.c.
1727 * Update the nickrec->founder in event_cumode in the Irssi SILC
1728 client. Affected file irssi/src/silc/core/silc-channels.c.
1730 * Fixed the CUMODE_CHANGE notify handling in the server when
1731 server and router are announcing their clients on channels.
1732 Now the mode changes are saved and notified correctly. The
1733 affected file is /silcd/packet_receive.c.
1735 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1736 They really did not replace the cache entry in the ID Cache.
1737 Now they do that. Affected file silcd/idlist.c.
1739 * Fixed the KICK notify handling in the Irssi SILC client to
1740 update the channel records so that the kicked client does not
1741 appear to be on the channel. The affected file is
1742 irssi/src/silc/core/silc-channels.c.
1744 * Always update the conn->current_channel when executing command
1745 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1747 * Fixed the KILL notify handling in Irssi SILC client to remove
1748 the killed client on all channels.
1750 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Fixed the silc_parse_command_line to remove extra spaces
1753 from the start and end of the arguments. Affected file is
1754 lib/silcutil/silcutil.c.
1756 * Cancel and free any active protocol in the function
1757 silc_server_close_connection. Affected file silcd/server.c.
1759 * Cancel and free any active protocol in the function
1760 silc_client_close_connction. Affected file is
1761 lib/silcclient/client.c.
1763 * Do not execute the KILL command for clients that are in
1764 history (ie. they are not in the network). Affected file is
1767 * Fixed KILL notify handling, client does not crash anymore.
1768 Affected file irssi/src/silc/core/silc-channels.c.
1770 * Reduced the default packet buffer size from 2048 to 1024 in
1771 lib/silccore/silcpacket.c.
1773 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1774 counter to the SKE context that is incresed when the SKE library
1775 performs async operation outside the library. If the outside
1776 process frees the SKE context and FREED status will be set
1777 and the library will detect after the sync operation that the
1778 libary is freed. The affected files are
1779 lib/silcske/silcske[_status].[ch].
1781 * Resolve the client entry information in the function
1782 silc_client_channel_message to assure that NULL pointer is not
1783 passed as client entry to the application. */
1785 * Fixed the task timeout calculation to assure that there is
1786 never negative timeouts. The affected file is
1787 lib/silcutil/silcschedule.c.
1789 * Fixed the channel user mode notification sending in server.
1790 It was sent point-to-point to the router (or to server by router)
1791 but it needs to be destined to a channel. The routines now
1792 supports sending the channel user mode notifys to the channels
1793 when announcing clients and channels. Affected files are
1794 silcd/server.c and silcd/packet_receive.c.
1796 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1797 It did not actually replace the old channel entry in the cache.
1798 Affected file lib/silcclient/client_notify.c.
1800 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Fixed a possible crash in silc_packet_send_prepare. It now
1803 assures always that there is enough space in the buffer and
1804 at the tail area of the buffer (for MAC).
1806 Fixed the inbound buffer reallocation in silc_packet_read.
1807 It was old code and did not handle the reallocation correctly.
1810 The affected file is lib/silccore/silcpacket.c.
1812 * Fixed buffer overflow in silc_parse_nickname in the file
1813 lib/silcutil/silcutil.c.
1815 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * make install generates new server keys only if there is not
1820 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1822 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1823 Added check that if the NOREPLY is set then we will not send
1824 the away message. This avoids infinite loop of away messages
1825 if both clients are away. The affected file is
1826 lib/silcclient/client_prvmsg.c.
1828 * Fixed client crash if /NICK was given without arguments.
1829 Affected file lib/silcclient/command.c.
1831 * Server does not send the invite list in INVITE command back
1832 to the client if the list was not altered. Added this notion
1833 to the protocol spec as well. Affected file silcd/command.c.
1835 Fixed possible crash in INVITE command by checking the
1836 value of silc_server_get_client_route command.
1838 * Fixed the INVITE notify type handling. The arguments are now
1839 taken in correct order and client does not crash. The affected
1840 file is irssi/src/silc/core/silc-channels.c.
1842 Removed the "Inviting xxx to channel" message from the
1843 client library away and let the application handle it.
1844 Affected file lib/silcclient/command.c. Added that message
1845 to Irssi SILC client's message formats.
1847 * Fixed CMODE command crash in client. It now checks the
1848 amount of arguments correctly and does not crash. The affected
1849 file is lib/silcclient/command.c.
1851 * Do not create new channel automatically in silc_channels_join
1852 but check whether the channel by that name already exists.
1853 Affected file irssi/silc/core/silc-channels.c.
1855 * Do not send the SERVER_SIGNOFF to router if the disconnected
1856 entity was the router. Affected file silcd/server.c.
1858 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1859 SILC client as it was missing from there.
1861 Added the handling of the KICK notify to the Irssi SILC client
1862 as it was missing. Added "you have been kicked" message to
1863 Irssi SILC client's message modules formats.
1865 Added the handing of the KILL notify to the Irssi SILC client
1866 as it was missing. Added the kill message module formats
1869 The affected file is irssi/src/silc/core/silc-channels.c.
1871 * The router did not save the channel mode the server announced.
1872 Affected file silcd/packet_receive.c.
1874 * Fixed a possible crash in INFO command in server. If the
1875 server did not provide the server info it crashed. Affected
1876 file silcd/command.c.
1878 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Fixed the GETKEY command in the server to check also the
1881 global list. Otherwise the GETKEY would not work correctly
1882 in normal SILC server. Affected file silcd/command.c.
1884 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Fixed GETKEY crash, it crashed if the command did not succseed.
1888 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1891 is now real and not just an macro interface to GMP.
1893 Removed the entire GMP from the source tree and imported new
1894 NSS MPI library instead. Reason for removing GMP is that it is
1895 extremely large and compiles extremely slow. The NSS MPI
1896 is only a few files and compiles in less than 10 seconds.
1897 The speed is also about the same as GMP. The MPI is imported
1898 to lib/silcmath/mpi.
1900 If the system has GMP installed we will still use the GMP.
1901 If it is not then the NSS MPI will be compiled.
1903 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * Merged a long nickname (127 characters long) crash bugfix from
1906 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1908 * Merged a freed memory reference bugfix from Irssi CVS tree.
1909 Affected file irssi/src/core/commands.c.
1911 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Added the server's public key sving and verification to the
1914 server when performing the SKE. This was missing and the
1915 remote server's (or router's) public key was accepted without
1916 checking whether we have it previously or trust it at all.
1917 Affected file silcd/protocol.c.
1919 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Check in the silc_server_timeout_remote if protocol is active
1922 and make sure that the protocol's final callback is called so
1923 that all memory if freed. Affected file silcd/server.c.
1925 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1927 * silc_server_whois_send_reply crashed the server if the nickname
1928 was 127 characters long. Affected file silcd/command.c.
1930 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Added sanity check to the silc_server_new_client. If the hostname
1933 is provided inside username then check that the provided hostname
1934 really is the same as the resolved one. If the hostname was not
1935 resolved then check it from the public key. Affected file is
1936 silcd/packet_receive.c.
1938 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1939 if the server disconnected us and the connection is not valid
1940 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1942 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1943 the library to the lib/silcutil/silcutil.[ch].
1945 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1947 * Close log file after open. Affected file
1948 lib/silcutil/silclog.c.
1950 * Check whether sock == NULL in silc_client_send_packet and return
1951 if it is. Affected file lib/silcclient/silcclient.c.
1953 * Check rec->entry == NULL in the Irssi SILC Client before
1954 sending the channel message. Affecte file is
1955 irssi/src/silc/core/silc-servers.c.
1957 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Merged a splitted window bugfix from Irssi CVS tree. The
1960 affected file is irssi/src/fe-text/textbuffer-view.c.
1962 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1963 It did not print nickname.
1965 * Improved the distributions system a bit.
1967 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1969 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1970 irssi/src/fe-text/gui-window.c.
1972 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1973 to in-active server. The affected file is
1974 irssi/src/silc/core/client_ops.c.
1976 * Resolve the client in USERS command reply if the entry does
1977 not have username resolved. The affected file is
1978 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1979 command to WHOIS command to really resolve stuff. The USERS
1980 is not used any more in any critical section so WHOIS can
1981 be used even though it might be slower than IDENTIFY.
1983 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1986 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Changed the protocol API a bit more consistent in the
1989 lib/silccore/silcprotocol.[ch].
1991 * Changed the following headers to ROBODoc format:
1993 lib/silccore/silcpayload.h
1994 lib/silccore/silcprotocol.h
1995 lib/silccore/silcsockconn.h
1997 All core library headers are now formatted.
1999 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Fixed a bug in Irssi SILC client; do not show that you are
2002 server/router operator if you really are not. Affected file is
2003 irssi/src/silc/core/client_ops.c.
2005 * Renamed silc_command_free_payload to silc_command_payload_free.
2006 Affected file lib/silccore/silccommand.h
2008 * Added silcmath.h to include the prototoypes of various routines
2009 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2012 * Changed the following headers to ROBODoc format:
2014 lib/silccore/silcchannel.h
2015 lib/silccore/silccommand.h
2016 lib/silccore/silcid.h
2017 lib/silccore/silcidcache.h
2018 lib/silccore/silcmode.h
2019 lib/silccore/silcnotify.h
2020 lib/silccore/silcpacket.h
2021 lib/silcmath/silcmath.h
2023 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Added checking to the server code not to start the server if
2026 ciphers and stuff are not configured properly. Affected files
2027 silcd/serverconfig.[h] and silcd/server.c.
2029 * Changed the layout of the header files of the public interfaces
2030 in the SILC libraries. The new layout supports ROBODoc
2031 documentation tool (and some others) so that it is easy to create
2032 a library reference manual. All the other headers and source
2033 code must still follow the CodingStyle document. Also source
2034 code must not include these ROBODoc stuffs, only the headers.
2035 Furthermore, all public interface headers must now be named
2036 by using `silc' prefix, example: silcapi.h, silccipher.h.
2037 Some files were renamed due to this. All the other headers
2038 must not be used as public interfaces. I will update the
2039 CodingStyle document later. Changed following headers, so far:
2041 lib/silcclient/silcapi.h
2042 lib/silccore/silcauth.h
2043 lib/silccore/silcprivate.h
2044 lib/silccrypt/silcdh.h
2046 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Removed silc_client_packet_send_flush from the client library
2051 as it is not needed. Affected file lib/silcclient/client.[ch].
2053 * Added printing of message of unresolved authentication method
2054 to the Irssi SILC client. Added it to the module formats.
2055 Removed the same message from the client library.
2057 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Added new distribution feature, DISTLABEL. Every distribution
2060 can define own preprocessor label that can be used in the
2061 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2062 file distributions, acconfig.h.pre and prepare.
2064 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Added Makefile.defines_int to include the actual definitions
2067 for Makefile.defines.in. Tested the new distribution system,
2068 created distributions and tested installation.
2070 * Added AWAY message printing to the Irssi SILC client. Added
2071 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2073 * Added SCONNECT command to call the SILC's CONNECT command.
2074 Cannot use CONNECT directly since Irssi uses that internally.
2075 Affected file irssi/src/silc/core/silc-servers.c.
2077 Added ACTION local command. It is same as ME command but takes
2078 the channel as mandatory argument.
2080 Rewrote some of the Irssi's help files to suite for SILC
2083 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Added Makefile.defines[.in] that should for now on be included
2086 in all Makefile.am file in the source tree. That file includes
2087 all common compilation definitions for SILC source tree.
2089 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * Minor changes to the ./prepare script to change the package
2092 name according the distribution name to the configure.in.
2094 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Created new distribution system. Added file `distributions'
2097 that defines all the distributions that can be created out of
2098 the SILC source tree. The ./prepare script now reads that
2099 file to determine how to prepare the distributions. The
2100 first argument to the ./prepare is the name of the distribution
2101 and second is the version of the distribution. If given
2102 without arguments it creates the default (toolkit) distribution
2103 with the default version (defined in ./prepare).
2105 All Makefile.am files that are subject to the distributions
2106 are now named as Makefile.am.pre. These are ./Makefile.am
2107 and lib/Makefile.am. Others may be changed later.
2109 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * Added invite list, ban list, some key management and connection
2112 error message printing to module formats in the Irssi SILC client.
2114 * Added new silc_client_set_away_message to set the away message
2115 that is back to the person who sent private message. The
2116 affected file lib/silcclient/silcapi.h and the
2117 lib/silcclient/client_prvmsg.c.
2119 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Fixed the private message sending in the Irssi SILC client,
2122 added local command KEY to the Irssi SILC client.
2124 Added key management and key agreement message formats to the
2125 irssi/src/fe-common/silc/module-formats.[ch].
2127 Added USERS (alias WHO) printing, server/router operator
2128 indication and LIST command printing to the module formats.
2130 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Fixed channel joining notify handling, cumode notify handling
2133 from Irssi SILC client.
2135 * Added SILC specific module-formats to the Irssi SILC client so
2136 that SILC specific message hilighting, colors etc is possible.
2137 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2139 Added channel mode, channel user mode, actions, notices,
2140 whois and whowas printing to the the module-formats.c.
2142 * Fixed a bug in channel deletion in the server. The channel
2143 is not left to the cache even if the channel founder auth mode
2144 is set when there are no users anymore on the channel. Affected
2145 file silcd/server.c.
2147 * The silc_net_localhost now resolves the entire hostname including
2148 the domain name. Affected file lib/silcutil/silcnet.c.
2150 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Changed the ask_passphrase client operation to be ascynchronous.
2153 It has now a completion callback and a context that the
2154 application must call after it has got the passphrase from
2155 the user. Affected files lib/silcclient/silcapi.h,
2156 lib/silcclient/protocol.c, lib/silcclient/command.c and
2159 Added SilcAskPassphrase callback that the application calls
2160 to deliver the passphrase to the library.
2162 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2163 The public key verification and especially a certificate
2164 verification is asynchronous procedure.
2166 Added new SILC_SKE_STATUS_PENDING status to indicate the
2167 request is pending and a callback will be called to finalize
2170 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2171 indicate that remote end did not send its public key (or
2172 certificate), even though we require it. Added check for this
2173 condition in the SKE. This was a security bug, now fixed.
2175 Defined new SilcSKEVerifyCbCompletion callback that is called
2176 when the verification process is completed.
2178 The affected files lib/silcske/silcske_status.h and
2179 lib/silcske/silcske.[ch].
2181 * Changed the verify_public_key client operation to be async
2182 as well. Defined SilcVerifyPublicKey callback that is used to
2183 indicate the success of the public key verification process.
2185 Changed the server and client to use the new async client
2188 * Changed the Irssi SILC client's internal scheduler to be called
2189 twice as many times as it used to be. As a result the client
2190 should be a bit faster now. Affected file is
2191 irssi/src/silc/core/silc-core.c.
2193 * Added support to Irssi SILC client of asynchronous public key
2194 verification and passphrase inquiry. Affected file is
2195 irssi/src/silc/core/silc-core.c.
2197 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Do not say "You have left channel %s" in client library.
2200 Moved it to the application. Affected files are
2201 lib/silcclient/command.c and silc/client_ops.c.
2203 * Fixed silc_client_get_clients. Command context was not
2204 duplicated and was freed memory in the callback. Affected
2205 file lib/silcclient/idlist.c.
2207 * Do not say "you are now talking..." on JOIN command in the
2208 client library. The appliation must handle it.
2210 * Do not say ".. changed topic to" in command reply in the
2211 client libary. The application must handle it.
2213 * Fixed TOPIC command sending in the client library.
2215 * Fixed a memory leak in silc_client_command_free in the file
2216 lib/silcclient/command.c.
2218 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Imported a modified version of Irssi client to the source tree.
2221 The Irssi will be used to create a new client called
2222 Irssi SILC. Imported to irssi/.
2224 Added silc_core_init_finish function to the Irssi. Affected
2225 file irssi/configure.in.
2227 A lot changes in the Makefile.ams around the irssi tree.
2229 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Do not rehash if the new size is same as the old size of the
2232 hash table, in the silc_hash_table_rehash*. The affected file
2233 lib/silcutil/silchashtable.c.
2235 * Replaced hash_table_del_by_context calls from the server
2236 (when channel->user_list and client->channels) to the
2237 hash_table_del as it is sufficient and faster.
2239 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Added silc_hash_table_list, silc_hash_table_get and the
2242 SilcHashTableList structure to provide an alternative way to
2243 traverse the hash table. The affected files are
2244 lib/silcutil/silchashtable.[ch].
2246 * Changed the server's idlist routines to use the hash table
2247 routines to optimize the code.
2249 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Replaced the client entry's `channel' list and channel entry's
2252 `user_list' list to hash tables for optimized lookup. Changed
2253 the code to use the hash table interface around the code.
2254 Affected file lib/silcd/idlist.[ch].
2256 * Added `auto_rehash' boolean argument to the function
2257 silc_hash_table_alloc to indicate whether the hash table should
2258 auto-rehash when it thinks is appropriate time. It will
2259 increase the hash table size if the there is twice as much
2260 entries in the table than the size of the table, and will
2261 decrease the size if there are twice as less entries than
2262 the size of the table.
2264 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2268 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * silc_idcache_purge_by_context deletes the entry now by context
2271 as it is supposed to do. Affected file lib/silccore/idcache.c.
2273 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2274 client is not anymore valid (WHOWAS givens the info) and not
2275 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2277 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Removed the `data' and `data_len' arguments from the ID Cache
2280 interfaces and added `name' argument. ID Cache does not handle
2281 anymore the binary data only a names associated with given ID.
2283 * When hashing a Client ID with silc_hash_id the entire ID is
2284 not hashed anymore, instead only the hash of the Client ID is
2285 hashed. This way we can access the Client ID from the cache
2286 with Client ID but with the hash of the ID (which is a hash of
2287 the nickname) as well without any difference in performance.
2289 Added also silc_idcache_find_by_id_one_ext to do one on one
2290 searching when we have the actual ID. Added also function
2291 silc_hash_client_id_compare. The affected files are
2292 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2294 * When hashing the name associated with a ID it is always done
2295 in lowercase. This way we can access the cache without worrying
2296 about case-sensitivity, even though, for example nicknames are
2299 * Fixed a bug in server with channel message sending. It put
2300 wrong ID type as destination ID. The affected file
2301 silcd/packet_send.c.
2303 * silc_idcache_del_by_context now deletes from all hash tables
2304 by context. Affected file lib/silccore/idcache.c.
2306 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Changed the client library to use the new ID Cache interface.
2309 Changes around the source tree.
2311 * Added silc_hash_table_rehash_ext to rehash with specific
2312 hash function. Affected file lib/silcutil/silchashtable.[ch].
2314 * Added silc_hash_string_compare to compare two strings in the
2315 hash table. Affected file lib/silcutil/silcutil.[ch].
2317 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Added new function silc_idcache_del_by_context into the
2320 lib/silccore/idcache.[ch].
2322 * Changed the server's ID list routines to use the new ID Cache
2323 interface. Changes around the source tree.
2325 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Added silc_hash_table_del[_by_context]_ext functions in to the
2328 lib/silcutil/silchashtable.[ch].
2330 Removed silc_hash_table_find_all* routines and added new
2331 silc_hash_table_find_foreach to replace them.
2333 Added silc_hash_table_replace_ext function as extended
2334 replacing function. Separated the simple hash table interface
2335 from the extended hash table interface in the file
2336 lib/silcutil/silchashtable.h.
2338 * Fixed minor bugs and changed it to use some of the new
2339 hash table functions in lib/silccore/idcache.c
2341 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2343 * Added new function silc_hash_table_find_all to return all keys
2344 in the hash table by the specified key. As the hash table is
2345 collision resistant it also makes it possible to have several
2346 duplicate keys in the hash table. This function may be used to
2347 find all of the keys from the hash.
2349 Added user_context arguments to the SilcHashFunction,
2350 SilcHashCompare and SilcHashDestructor to deliver user specified
2353 Added new fuctions silc_hash_table_find[_all]_ext to do
2354 extended lookup with specified hash and compare functions and
2355 specified user contexts.
2357 Added new function silc_hash_table_add_ext to add the key
2358 with specified hash function and user context.
2360 Added new function silc_hash_table_foreach to traverse all
2361 entrys in the hash table. Added SilcHashForeach callback
2364 Added new function silc_hash_table_del_by_context to delete
2365 the entry only if the context associated with the key matches.
2367 Affected files are lib/silcutil/silchashtable.[ch].
2369 * Removed silc_hash_[server/client/channel]_id and added just
2370 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2371 silc_hash_id_compare to compare two ID's using as the hash table
2372 comparison function. Added also silc_hash_data to hash
2373 binary data and silc_hash_data_compare to compare it.
2375 * Removed silc_idlist_find_client_by_hash as it is not needed
2376 anymore. Affected file silcd/idlist.[ch].
2378 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2379 to use internally the SilcHashTable. The new ID Cache is a lot
2380 faster than the old one. Some of the ID Cache interface was also
2381 rewritten and obsolete and stupid functions were removed.
2383 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Added entry_count field to the SilcHashTable to keep the number
2386 of the entries in the table. Implemented the function
2387 silc_hash_table_rehash. Added new function
2388 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2390 Fixed a minor bug in silc_hash_table_free.
2392 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2393 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2394 into the lib/silcutil/silcutil.[ch].
2396 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Implemented a collision resistant hash table into the
2399 lib/silcutil/silchashtable[ch]. See the header and the source
2400 for the SilcHashTable API.
2402 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Merged dotconf version 1.0.2 into lib/dotconf.
2406 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Do not compile anything in lib/silcsim/* if the SIM support
2409 is not enabled. The tree should now compile without problems
2412 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Compiled the SILC under cygwin. Compiled and tested briefly
2415 without problems. More tests needed. The SIMs didn't compile
2418 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2420 * Fixed possible crash in silc_get_username in the
2421 lib/silcutil/silcutil.c.
2423 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Fixed a va_arg in silc/client_ops.c.
2427 * Oops, RC5 routines were named AES and caused some problems
2428 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2430 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Added new SilcIDIP structure into the lib/silccore/id.h and
2433 replaced the old `ip' fields from all SILC ID's to that type.
2434 This is a step towards IPv6 support.
2436 The silc_id_get_len takes now the ID as an extra argument.
2437 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2438 both IPv4 and IPv6 based ID's.
2440 The affected files are lib/silccore/id.[ch] and other files
2441 around the tree using these routines.
2443 * Removed the ID length arguments in server from various
2444 silc_server_send_notify_* routines -> they are not needed
2447 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Fixed memory leak in silc_encode_pem_file in the file
2450 lib/silcutil/silcutil.c.
2452 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Check minor version as well in the SKE. Affected files are
2455 silcd/protocol.c and lib/silcclient/protocol.c.
2457 * Added --identifier option to the server so that an identifier
2458 can be when creating the public key for the server. Affected
2459 file is silcd/silcd.c.
2461 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2462 lib/silccrypt/silcpkcs.c.
2464 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Register default ciphers and stuff when using -C option with
2467 the server. Affected file sildc/silcd.c.
2469 * Put back the servers public key filename format, it is better
2470 than the new one. For now, the client keys are saved with the
2471 new filename format. The affected file silc/client_ops.c.
2473 * Implemented the Cipher API for the rest of the ciphers that
2474 did not implement it or implemented it the wrong way.
2476 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Register default ciphers and stuff when using the -S option
2479 in the client. Affected file silc/silc.c. Same also when
2480 creating new key pair with -C option.
2482 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Fixed the silc_verify_public_key client operation function to
2485 save the public keys differently. The fingerprint is now
2486 used as filename and not the hostname. This way also the
2487 client keys are saved uniquely and not with hostnames. The
2488 affected file is silc/client_ops.c.
2490 * Trimmed the silc_hash_fingerprint function to remove extra
2491 whitespaces from the end of the fingerprint. The affected
2492 file is lib/silccrypt/silchash.c.
2496 * Added silc_cipher_register_default function to register all
2497 default ciphers. It can be used when configuration files
2498 does not exist and the application does not want any specific
2499 ciphers in any specific order.
2501 The SilcDList is now used as silc_cipher_list dynamically
2502 allocated cipher list. Removed the static list all together
2503 and now all ciphers must be allocated to the dynamic list.
2504 The silc_cipher_alloc routine was changed to check only the
2507 All silc_cipher_* routines that used to return int returns
2510 The affected files lib/silccrypt/silccrypt.[ch].
2512 * The same thing was done to silc_hash_* as for silc_cipher_*
2513 routines. Affected files lib/silccrypt/silchash.[ch].
2515 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2516 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2517 Added also silc_pkcs_[un]register[_default] functions.
2518 Removed the data_context from the PKCS API.
2520 * Added silc_hmac_register_default function to register default
2521 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2522 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2523 to unregister all hmacs at once.
2525 * Register the default ciphers, hash functions, PKCSs and HMACs
2526 if client's configuration file does not exist. The affected
2529 * The client did not load the hash functions from the SIM
2530 modules at all. Added support for this. Affected file is
2531 silc/clientconfig.c.
2533 * When decoding public key with silc_pkcs_public_key_decode, check
2534 the supported algorithm only if PKCS are registered. Affected
2535 file lib/silccrypt/silcpkcs.c. The same was done with the
2536 silc_pkcs_private_key_decode.
2538 * Fixed the SILC List routines to keep the list always in order.
2539 It used to change the list's order when traversing the list but
2540 not it preserves the order. Affected file lib/trq/silclist.h.
2542 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Added the client library to use the SilcSocketConnection's
2545 reference counter (by silc_socket_dup) to prevent the bug that
2546 the socket object may be freed underneath async operation.
2548 * The name resolv library checking fixes in the configure.in.pre.
2551 * Created new version of the protocol drafts for future
2552 development. The -03 drafts are the ones that will be changed
2553 in the trunk now and the -02 will remain as they are.
2555 * Send list of CUMODE notifys to the router when announcing
2556 the channel users to the router. Affected file silcd/server.c.
2557 If the router receiving channel founder CUMODE for a channel
2558 that already has channel founder it will send CUMODE notify
2559 to the sender to remove the channel founder rights from the
2560 announced client. Affected file silcd/packet_receive.c.
2562 * The CUMODE notify may now use Server ID as well as the entity
2563 who changes the mode. Updated protocool specs.
2565 * Updated INSTALL and README files.
2567 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * New web pages in the http://silc.pspt.fi. The pages was
2574 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Implemented the [DenyConnectin] config section in the server.
2577 Added silc_server_config_denied_conn to check whether incoming
2578 connection is denied. Affected file silcd/serverconfig.[ch].
2580 * Do not check the ports when checking the incoming configuration
2581 data if the port is 0, meaning any. Affected file is
2582 silcd/serverconfig.c.
2584 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Fixed buffer overflow in silc_string_compare in the file
2587 lib/silcutil/silcutil.c.
2589 * Fixed double free in silc_server_command_leave in the file
2592 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Fixed the version checking in the server. Affected file is
2597 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Fixed the configuration data fetching when accepting new
2600 connections in the server. Affected file silcd/server.c.
2602 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2604 * Added `sender_entry' argument to the function
2605 silc_server_packet_relay_to_channel so that we can check
2606 whether some destination actually belongs to the same route
2607 the sender belongs (ie, we must not resend the packet to the
2608 sender). Affected file silcd/packet_send.[ch].
2610 * Added `servername' field to the SilcClientEntry in the server
2611 to hold the name of the server where client is from. Affected
2612 file is silcd/idlist.h.
2614 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Moved the channel message encrypting in the router betwen
2617 router connections from silc_server_channel_message to the
2618 silc_server_packet_relay_to_channel since we want to check
2619 whether we have anybody channel before encrypting anything.
2620 Affected files silcd/packet_[receive/send].c.
2622 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Fixed the [AdminConnection] server config section to support
2625 multiple entries. Affected file silcd/serverconfig.c.
2627 * Added support into the server to check the validity of the
2628 incoming connection before executing any KE or authentication
2631 * The connection configuration is now saved to the KE and
2632 connection auth protocol contexts and not fetched anymore in
2633 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2635 * The local hosts listenning address and port is also resolved
2636 now when starting the server. We want to have the socket object
2637 to include the real address and port for the listener. Added
2638 new function silc_net_check_local_by_sock into the files
2639 lib/silcutil/silcnet.[ch].
2641 * Fixed a broadcast bug in server -> do not broadcast if we
2644 * Fixed a routing bug. Do not route broadcast packets ever.
2645 Broadcast packets must be processed always and not routed since
2646 they may be destined to some other host than yourself and thus
2647 would get routed without no good reason. Affected file is
2650 * Added function silc_server_config_is_primary_route to check
2651 whether primary router connection has been configured (a router
2652 configuration that we are initiating). If there is not, we
2653 will assume that there is only two routers in the SILC network
2654 and we will use the incoming router connection as our primary
2655 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2657 * Changed the order of the broadcasting. Broadcast _after_ the
2658 packet has been processed not before. Affected file is
2661 * Fixed a [ClientConnection] parsing bug. The port was never
2662 parsed correctly thus resulting to port 0. Affected file
2663 silcd/serverconfig.c.
2665 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2666 argument and did not set the broadcast packet flag. Affected
2667 file silcd/packet_send.c. Fixed same bug in the function
2668 silc_server_send_notify as well.
2670 * If we receive NEW_ID packet for our own ID in the server, ignore
2673 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Removed the nickname from the Private Message Payload.
2678 Updated the code and the protocol specs.
2680 * Updated protocol specs for submitting to the IETF.
2682 * Tweaked the Random Number Generator a bit. Affected file
2683 lib/silccrypt/silcrng.c. Exported a new function
2684 silc_rng_[global]_add_noise which can be used to add more
2687 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Do not parse packets with different timeout when protocol
2690 is active -> may cause problem with rekey. Affected file
2693 * When server receives signoff notify it must not create
2694 new channel key if the client is on any channels since the
2695 sender of the signoff notify will create it.
2697 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Added printing of error messages during SKE protocol from the
2700 failure packet sent by server during SKE. Affected file
2703 * Removed the client's failure_callback handling with timeout
2704 and handle it immediately when received.
2706 * The SKE library returned wrong type in SUCCESS and FAILURE
2707 packets. They must be 32 bit MSB not 16 bit MSB.
2709 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Ok, rewrote the logic of the re-key and now it seems to work.
2712 I tested it on high traffic with frequent re-keys without
2713 problems. Added hmac_receive (and renamed hmac to hmac_send)
2714 in SilcClientConnection in lib/silcclient/client.h and
2715 in SilcIDListData in silcd/idlist.h. Also, removed the
2716 SilcPacketParserContext's cipher and hmac fields as they are
2717 not needed anymore and actually caused some problems when
2718 the ciphers and hmac's changed underneath the packet parser.
2720 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * If re-key protocol is active then process the incoming packets
2723 synchronously since we must assure that icoming packets encrypted
2724 with the old key is processed before the new keys is set to
2725 use. This is true other packets than for REKEY packets.
2726 Affected file silcd/server.c. The same was done to client library
2727 as well, affected file lib/silcclient/client.c.
2729 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Fixed bug in client and server to accept the force send if
2732 the packet is send from silc_[server/client]_packet_process
2733 function. Otherwise the packets are never delivered, oops.
2735 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Disable force sending of packets when REKEY protocol is active.
2738 We must assure that no packet is sent directly when rekey is
2739 performed. All packets must be sent through packet queue.
2740 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2741 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2742 function is silc_[server/client]_packet_send_real to check
2745 * Replaced the SIM paths from example config files to
2746 /usr/local/modules. Also, make install creates now
2747 /usr/local/silc/logs directory to hold all the SILC server
2750 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Made the configure.in.pre work on Solaris. Patch by salo.
2754 * Made all ciphers compatible with non-x86 machines. Defined
2755 CBC mode macros into lib/silccrypt/ciphers_def.h.
2757 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Fixed the make install.
2761 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * When MAC computation fails the silc_packet_decrypt returned 0
2764 even though it was supposed to return -1. Fixed this. The
2765 affected file is lib/silccore/silcpacket.c.
2767 * Do not replace the config files in /etc/silc (in make install)
2768 if they already exist. Affected file ./Makefile.am.
2770 * Do not send re-key packets immediately but through packet queue.
2771 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2773 * Changed silc_net_check_host_by_sock to return FALSE if the
2774 IP/DNS could not be resolved. Though, it returns the IP address
2775 now even if it could not resolve it (but returns also FALSE).
2776 Affected file lib/silcutil/silcnet.[ch].
2778 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2780 * Added silc_pkcs_decode_identifier to decode the public key's
2781 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2782 Added also silc_pkcs_free_identifier. Added also new context
2783 SilcPublicKeyIdentifier.
2785 * Added -S option to the silc client. It is used to dump the
2786 contents of the specified public key file.
2788 * Changed the PKCS api to return the public key length when
2789 setting the public key.
2791 * Fixed a fatal bug in the public and private key file loading.
2792 Affected file lib/silccrypt/silcpkcs.c.
2794 * Execute the packet parsing for client with zero (0) timeout
2795 if the protocol is active. Affected file silcd/server.c.
2797 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Made the key generation options to the silcd program. Added
2800 -C option, equivalent to client's option.
2802 * Added new [ServerKeys] config section to the server. It
2803 configures the server's public and private key.
2805 * Defined generic Public Key Payload into the protocol
2806 specification to send specific type of public keys and
2809 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2810 public key or certificate.
2812 * Implemented the GETKEY command to the server and to the
2813 client library and on user interface.
2815 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Made preliminary `make install' work.
2819 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2821 * Added SilcServerRekey context into silcd/idlist.h.
2823 * Added the PFS support as defined in the specification to the
2824 SKE protocol. Affected files lib/silcske/*.c.
2826 * Added `ske_group' field to the SilcServerRekey context to hold
2827 the number of the SKE group that is used with PFS in re-key.
2828 Affected file silcd/idlist.h.
2830 * Added PFS re-key support to the server. Affected file is
2833 * Added silc_protocol_cancel to cancel execution of the next
2834 state of the protocol. Affected file is
2835 lib/silccore/silcprotocol.[ch].
2837 * Added the re-key support with and without PFS to the client
2838 library. Re-key is performed once in an hour, by default.
2840 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2841 Added silc_client_rekey_callback and silc_client_rekey_final.
2842 Affected files are lib/silcclient/protocol.[ch] and
2843 lib/silcclient/client.[ch].
2845 * Removed the `hmac_key' and `hmac_key_len' fields from the
2846 SilcClientConnection structure; not needed. Affected file is
2847 lib/silcclient/client.h.
2851 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2853 * Do not ask whether user wants to use the negotiated private key
2854 for private messages, just use it. Affected file is
2855 silc/local_command.c.
2857 * Added `send_enc_key' and `enc_key_len' fields to the
2858 SilcIDListData structure since they are needed in the re-key
2859 phase. Affected file is silcd/idlist.[ch].
2861 * Implemented the simple re-key protocol into the server.
2862 Affected files silcd/server.c and silcd/protocol.[ch]. The
2863 re-key will be performed once in an hour, by default.
2865 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2866 Added silc_server_rekey, silc_server_rekey_callback and
2867 silc_server_rekey_final.
2869 * Removed Tunneled flag from the protocol. Updated the code
2870 and the specifications.
2872 * Adde `pfs' field to the SilcIDListData to indicate whether
2873 the PFS is to be performed in the re-key. Affected file is
2876 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2879 int64 of at least the xintXX size. If void * is less that 4
2880 bytes uint32 * will be used. Defined bool as boolean.
2882 * Changed _ALL_ unsigned long and unsigned int to uint32,
2883 unsgined short to uint16 in the source tree.
2885 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2886 not handle clients that has entry->data.registered == FALSE.
2887 They are not in the network anymore. Affected file is
2890 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Implemented the sending of the SERVER_SIGNOFF notify in the
2893 server. Affected file is silcd/server.c.
2895 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2896 Added also silc_notify_payload_encode_args into the
2897 lib/silccore/silcnotify.[ch].
2899 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2900 Affected file silcd/packet_receive.c.
2902 * Implemented the SERVER_SIGNOFF notify handling in the client
2903 library. Affected file lib/silcclient/client_notify.c. Also,
2904 implemnted the printing of the SERVER_SIGNOFF info to the
2905 application. Affected file silc/client_ops.c.
2907 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2908 if the deleting was successful. Affected file silcd/idlist.[ch].
2910 * Added support for public key authentication in the connection
2911 authentication protocol in the client library. Affected file
2912 lib/silcclient/protocol.c.
2914 * Changed the server's silc_idlist_get_clients_by_* interface
2915 to support already allocated array so that new entries may be
2916 added to pre-allocated array. Affected file silcd/idlist.[ch].
2917 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2918 and command replies.
2920 * All command reply functions in the server now calls the
2921 pending command callback even if error occured. This way the
2922 error will be delivered to the client as well. Affected files
2923 silcd/command.c and silcd/command_reply.c.
2925 * Fixed INFO command to return local server's info if no server
2926 was provided. Affected file lib/silcclient/command.c.
2928 * Removed RESTART command for good. Updated the code and the
2931 * Rewrote parts of the task system. It is a bit simpler now.
2932 Removed unsued task priorities. The affected files are
2933 lib/silcutil/silctask.[ch].
2935 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Moved the USERS printing from the library to the application.
2938 Affected files lib/silcclient/command.c and silc/client_ops.c.
2940 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Added channel key re-key support. The re-key is perfomed
2945 only by the router and is done once in an hour. Added `rekey'
2946 field to the SilcChannelEntry in the server. Affected files
2947 silcd/server.c and silcd/idlist.h.
2949 * Added silc_task_unregister_by_context into the file
2950 lib/silcutil/silctask.[ch].
2952 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Added SILC_UMODE_GONE mode to indicate when the client is not
2955 present in the SILC network. Added also support to the local
2956 command AWAY that will set this mode. Added support of showing
2957 "xxx is gone" in WHOIS command. The USERS command shows the
2958 gone status as well.
2960 * Fixed setting server and router operator privileges in the
2961 server's UMODE command. Affected file silcd/command.c.
2963 * Merged the SKE KE1 and KE2 payloads into one payload. The
2964 new KE payload is equivalent to the old KE2 payload.
2966 Cleaned up the SKE Start Payload parsing. It now uses the
2967 simple buffer unformatting to do the parsing. A lot faster
2970 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2971 to the SKE that is used to indicate whether both of the SKE
2972 parties should perform authentication. By default only the
2973 responder performs authentication. By setting this flag also
2974 the initiator must do authentication. By default it is unset
2975 since in normal SKE case, client to server connection, only
2976 the responder should do authentication. When doing SKE between
2977 two clients both should perform authentication. Updated the
2978 code and the protocol specs.
2980 * A little fix to IDENTIFY command in the server. Search the
2981 client first by hash not nickname. Affected file is
2984 * Fixed the silc_client_close_connection to support closing
2985 the client to client connections wihtout deleting too much
2986 data. Affected file lib/silcclient/client.c.
2988 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2989 are received if protocol used to be active but is not anymore
2990 the application would crash due to NULL pointer dereference.
2991 Affected files silcd/server.c and lib/silcclient/client.c.
2993 * Added `hash' field to the SilcClientConnection to include
2994 the hash function negotiated in the SKE protocol.
2996 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2997 to set the channel founder authentication data. A client can
2998 claim the founder rights later by providing the authentication
2999 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3000 This way the channel founder can regain the channel founder
3001 privileges even it is left the channel. This works only on
3002 local server and the client must be connected to the same
3003 server to be able to regain the founder rights. Updated the
3004 protocol specs accordingly.
3006 Added support to the CMODE command in the client to set the
3007 founder auth data. Read the README to see how to set it.
3009 Added support to the CUMODE command to claim the founder
3010 rights. Read the README to see how to do it.
3012 Added support for the founder authentication to the Channel
3013 Entry in the server. Affected file silcd/idlist.h.
3015 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3016 server's CMODE command. Affected file silcd/command.c.
3018 * Added the following new functions into lib/silccore/silcauth.[ch]:
3019 silc_auth_get_method and silc_auth_get_data.
3021 * The server now saves the remote hosts public key to the
3022 SilcIDListData pointer. Affected file silcd/protocol.c.
3024 * The normal server now does not remove the channel entry from
3025 the cache if the founder authentication data is set. It used
3026 to remove it if the founder was the last one on the channel on
3027 the server and left the channel. The auth data is saved and
3028 if the channel is re-joined later the old entry is used with
3029 the old auth data. Affected files silcd/command_reply.c and
3032 * Removed the `pkcs' field from the SilcIDListData structure
3033 in the server; it is not used. Affected file silcd/idlist.h.
3035 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Fixed packet processing on slow links. Partial packets were
3038 never re-processed because the incoming data buffer was cleared
3039 by the application. Application must not directly clear the
3040 sock->inbuf, the packet processing routines handle it. Fixed
3041 this in client library and in server.
3043 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Fixed the WHOIS and IDENTIFY send reply function to really
3046 check whether to send list or just one entry. Affected file
3049 * Cleaned up the LEAVE command's channel key distribution. The
3050 affected file silcd/command.c.
3052 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3053 can enforce the channel mode as well. In that case the ID
3054 includes the ID of the server. The code now enforces the
3055 mode change if the router have different mode than the server.
3057 * The notify client operation with CMODE_CHANGE notify can now
3058 return NULL client_entry pointer if the CMODE was not changed
3059 by client. Application must check for this.
3061 * Added <Server ID> argument to INFO command to support server
3062 info fetching by Server ID.
3064 * Added silc_server_announce_get_channel_users to get assembled
3065 packets of channel users of the specified channel. Affected
3066 file silcd/server.[ch].
3068 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3069 was freed underneath the ID Cache.
3071 * Re-announce clients when the server received CHANNEL_CHANGE
3072 notify from the router. Affected file silcd/packet_send.c.
3074 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3077 crashed since it did not handle the fact that there is no cipher
3078 called "3" and didn't check the error condition. Now fixed.
3080 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3081 flag. It can be used to send message requests.
3083 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Implemented the RESTART command in the client.
3087 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3088 notice type messages. Added notice printing to the user
3091 * The channel keys are not re-generated if the channel's mode
3092 is PRIVKEY, ie private key on the channel exists. Affected
3093 files silcd/server.c and silcd/command.c.
3095 * Fixed a little bug in channel message delivery when channel
3096 private keys are set in the server. Affected file is
3097 silcd/packet_send.c.
3099 * Changed the setting on channel->on_channel = TRUE from the
3100 silc_client_save_channel_key to the JOIN command reply. The
3101 key payload is not received if the private channel key is set.
3102 Affected file lib/silcclient/command_reply.c and the
3103 lib/silcclient/client_channel.c.
3105 * When the CMODE_CHANGE notify is sent and the channel private
3106 key mode is removed the channel key must be re-generated in
3107 other cells as well. Added this support for the router in the
3108 silcd/packet_receive.c.
3110 * Added new local command NOTICE to send notice message on
3111 channel. Affected file silc/local_command.[ch].
3113 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Added new local command ME to the client. It is used to send
3116 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3117 some action. Affected file silc/local_command.[ch].
3119 * Changed channel_message and private_message client operations
3120 to deliver the message flags to the application. Added also
3121 the `flags' arguments to the silc_client_send_channel_message
3122 and silc_client_send_private_message functions. Affected file
3125 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Redefined the Private Message Payload to support private message
3128 keys and to support the new private message flags. Updated
3129 the protocol specs. Flags makes it possible to have for example
3130 CTCP style messages.
3132 * Added new type SilcPrivateMessagePayload and defined an API
3133 for it in the lib/silcclient/silcprivate.[ch].
3135 * Tested private message private keys successfully. Tested the
3136 private message key set, unset and list commands with the new
3139 * Redefined the Channel Message Payload to include the channel
3140 message flags (equal with private message flags) to support
3141 for example CTCP style messages.
3143 * Defined some of the message (for channel and private message)
3144 flags. Updated the protocol specs and added the flags to the
3145 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3147 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Added SilcKeyAgreementStatus type to the key agreement routines
3150 to indicate the current status and error if one occured.
3151 The status types are defined in the lib/silcclient/silcapi.h.
3153 * Added new local command KEY that is used to set and unset private
3154 keys for channels, set and unset private keys for private messages
3155 with remote clients and to send key agreement requests and
3156 negotiate the key agreement protocol with remote client. The
3157 key agreement is supported only to negotiate private message keys,
3158 it currently cannot be used to negotiate private keys for channels,
3159 as it is not convenient for that purpose.
3161 * Fixed a minor pending callback setting bug in the function
3162 silc_client_get_client_by_id_resolve, now the function works.
3163 Affected file lib/silcclient/idlist.c.
3165 * Added function silc_net_get_local_port to get local bound
3166 port by socket. Added to lib/silcutil/silcnet.[ch].
3168 * Added `sockets' and `sockets_count' fields to the SilcClient
3169 object. They hold the sockets of the listenning sockets in
3170 the client. Listenning sockets may be for example the key
3171 agreement server. Affected file lib/silcclient/client.[ch].
3172 Added functions the silc_client_add_socket and the
3173 silc_client_del_socket. They are exported to the application
3176 * Added ~./silc/clientkeys to support other client's public keys.
3178 * Renamed verify_server_key client operation to verify_public_key
3179 and added one argument to indicate the type of the connection
3180 (server, client etc.).
3182 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Added silc_server_connection_auth_request to handle the
3185 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3186 silcd/packet_receive.[ch].
3188 * Added silc_server_send_connection_auth_request into the
3189 silcd/packet_send.c to send the connection auth request packet.
3191 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3194 * Fixed the public key authentication in responder side in the
3195 server. The `auth_data' pointer includes the SilcPublicKey
3196 not the path to the public key. Affected file silcd/protocol.c.
3198 * Implemented the public key authentication in the initiator side
3199 in the server. Affected file silcd/protocol.c.
3201 * Removed the [RedirectClient] config section from the server
3202 configuration. Is not needed and I don't want to implement it.
3204 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Cleaned up the CMODE command in the server. It now works
3207 correctly and supports all the modes defined in the protocol.
3208 Affected file is silcd/command.c.
3210 * Added `hmac_name' field to the SilcChannelEntry in the server
3211 to hold the default HMAC of the channel. It can be set when
3212 creating the channel (with JOIN command). Affected files
3215 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3216 type to indicate the change of the current cipher and hmac
3217 on the channel. Client can safely ignore the <cipher> argument
3218 (if it chooses to do so) since the CHANNEL_KEY packet will
3219 force the channel key change anyway. The <hmac> argument is
3220 important since the client is responsible of setting the new
3221 HMAC and the hmac key into use.
3223 * Fixed the CMODE command in the client library as well.
3225 * Tested CMODE command in router environment successfully.
3227 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Show the version of the remote client (or server) when connecting
3230 to the server. It is logged to the log file. Affected file
3231 is silcd/protocol.c.
3233 * Fixed the KILLED notify handling in the client library. The
3234 client must be removed from all channels when receiving the
3237 Also, do not remove the client entry when giving the KILL
3238 command but when the KILLED notify is received.
3240 * Removed silc_idlist_find_client_by_nickname from the server.
3241 Not needed anymore. Affected files silcd/idlist.[ch].
3243 * Implemented the CHANNEL_CHANGE notify type handling to the
3244 server. Affected file silcd/server.c.
3248 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Added silc_server_send_notify_invite to send the INVITE
3251 notify between routers.
3253 * Implemented the INVITE command correctly to the server.
3255 * Implemented the INVITE notify type handling in the server.
3257 * Implemented the INVITE command to the client library and on the
3260 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Added function silc_server_get_client_resolve to find the
3263 client entry by ID from all ID lists and then resolve it
3264 (using WHOIS) if it cannot be found. Affected file is
3267 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Implemented the BAN command to the client library.
3271 * The JOIN command in the server now checks the invite list
3274 * Changed the silc_command_reply_payload_encode_va and the
3275 silc_command_payload_encode_va to support that if argument is
3276 NULL it ignores and checks the next argument. Affected file
3277 lib/silccore/silccommand.c.
3279 * Added silc_server_send_notify_ban to send the BAN notify
3280 type between routers.
3282 * Chaned the silc_notify_payload_encode to support that if
3283 argument is NULL it ignores and checks the next argument.
3284 Affected file lib/silccore/silcnotify.c.
3286 * Tested ban lists in router environment successfully.
3288 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Implemented BAN command to the server, in silcd/command.[ch].
3292 * Removed the BAN and INVITE_LIST modes from the CMODE command
3295 * Added function silc_string_match to regex match two strings.
3296 Affected files lib/silcutil/silcutil.[ch].
3298 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Redefined parts of the SilcChannelEntry in the server to support
3301 the new ban and invite lists.
3303 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Redefined the INVITE command. The same command can be used to
3306 invite individuals to the channel but also to manage the invite
3307 list of the channel (to add to and remove from the invite list).
3308 Updated the protocol specs.
3310 * Added new command SILC_COMMAND_BAN that can be used to manage
3311 the ban list of the channel. Updated the protocol specs.
3313 * Removed the channel modes: the SILC_CMODE_BAN and the
3314 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3315 in the CMODE command. The equivalent features are now available
3316 using INVITE and BAN commands. Updated the protocol specs.
3318 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3319 in the network about change in the current ban list. The notify
3320 type is not used by the client.
3322 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3323 support the invite lists.
3325 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Added new function silc_string_regexify that converts string
3328 including wildcard characters into regex string that can
3329 be used by the GNU regex library. Added into the file
3330 lib/silcutil/silcutil.[ch].
3332 Added silc_string_regex_combine to combine to regex strings
3333 into one so that they can be used as one regex string by
3334 the GNU regex library. Added into the file
3335 lib/silcutil/silcutil.[ch].
3337 Added silc_string_regex_match to match two strings. It returns
3338 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3340 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Imported GNU regex to the soruce tree into lib/contrib.
3343 Fixed some compiler warning from the regex.c.
3345 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Fixed MOTD command in the server to work in router environment.
3349 * Fixed the MOTD command in the client library to support
3350 the server argument in the command.
3352 * Added `nickname_len' argument to the silc_idlist_add_client
3353 in the server, as the `nickname' argument may be binary data
3356 * Added silc_idlist_get_channels to return all channels from
3359 * Implemented LIST command to the server. Affected file is
3362 * Implemented the LIST command to the client library and on the
3365 * Added [<user count>] argument to the LIST command reply.
3366 With private channels the user count is not shown.
3368 * Updated TODO and README.
3370 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * The client entry's data.registered must be TRUE even with
3373 global client entry on global client list. The data.registered
3374 is used to check whether the client is anymore in the network,
3375 for example with WHOWAS command so it must be valid.
3377 * Fixed the WHOWAS command in the server. It now actually works
3378 in router environment. Added function into silcd/command_reply.c
3379 silc_server_command_reply_whowas_save.
3381 * Added silc_idlist_purge function to the silcd/idlist.c
3382 to periodically purge the ID Cache.
3384 * Fixed INFO command in the server. It works now in router
3385 environment. Added <server name> argument to the INFO command
3386 reply. Updated the protocol specs.
3388 * Fixed minor bug in silc_idcache_purge to not purge if the
3389 expire value is zero.
3391 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3392 they were buggy because of the WHOWAS information.
3394 * Fixed local command MSG to handle the async resolving of
3395 the remote client properly. It used to fail the first MSG.
3396 Affected file silc/local_command.c.
3398 * Added `data_len' field to SilcIDCache context.
3400 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Update TODO. Todo in commands in the server.
3404 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3407 used by routers as broadcast packet to inform other routers
3408 about the changed user mode.
3410 Implemented the notify handling in the server. Affected file is
3411 silcd/packet_receive.c. Added the function
3412 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3414 * Added new generic Channel Payload and deprecated the New Channel
3415 Payload. The New Channel Payload is now the generic Channel
3418 * Added new argument `mode' to the silc_server_send_new_channel
3419 as it is required in the Channel Payload now.
3421 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3422 and created a new and real SilChannelPayload to represent the
3423 new generic Channel Payload. Implemented the encode/decode
3424 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3426 * Added silc_server_get_client_channel_list to return the list
3427 of channels the client has joined for WHOIS command reply.
3428 Affected file silcd/server.[ch].
3430 * Implemented the channel list sending in the WHOIS command reply
3431 in server and in the client.
3433 Implemented the channel list displaying on the user interface
3434 as well. Affected file silc/client_ops.c.
3436 * Added silc_channel_payload_parse_list to parse list of Channel
3437 Payloads. It returns SilcDList list of SilcChannelPayloads.
3438 Client for example can use this function to parse the list of
3439 channels it receives in the WHOIS command reply. The caller
3440 must free the list by calling silc_channel_payload_list_free.
3441 Affected files lib/silccore/silcchannel.[ch].
3443 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Added one new argument <user mode> to the WHOIS command reply
3446 to return the mode of the user in SILC. Updated the protocol
3449 Implemented it to the server and client.
3451 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Fixed the mode printing on the user interface on joining.
3454 Affected file silc/client_ops.c.
3456 * Implemented the UMODE command and user modes in general to the
3457 client library and to the user interface.
3459 * Implemented the UMODE command to the server.
3461 * The server now sends UNKNOWN_COMMAND error status if client sends
3462 unknown command. Affected file silcd/command.c.
3464 * All server commands now handle the command identifier the right
3465 way when sending the command reply to the client. The client can
3466 use to identify the command replies with the identifier.
3468 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Added silc_server_get_client_route to resolve the route to
3471 the client indicated by the client ID. Affected file is
3474 * Added silc_server_relay_packet as general function to relay
3475 packet to arbitrary destination. This deprecates functions
3476 like _send_private_message_key, _relay_notify etc. Affected
3477 file is silcd/packet_send.[ch].
3479 Removed silc_server_send_key_agreement,
3480 silc_server_send_private_message_key and
3481 silc_server_packet_relay_notify functions from the file
3482 silcd/packet_send.[ch].
3486 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3487 server. Affected file silcd/packet_receive.[ch].
3489 * Implemented the KILL command to the client. Implemented the
3490 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3491 Affected files lib/silcclient/command[_reply].c and
3492 lib/silcclient/client_notify.c. Implemented the KILL notify
3493 printing in the user inteface.
3495 * Fixed a lot silc_parse_nick memory leaks from the client
3496 library in the file lib/silcclient/command.c.
3498 * Changed the silc_server_send_notify_on_channels's `sender'
3499 argument from SilcSocketConnection to SilcClientEntry to
3500 check the sender as entry and not as connection object and not
3501 to send to the client provided as argument. The affected file
3502 is silcd/packet_send.[ch].
3504 * The notify packets that are destined directly to the client used
3505 to not to be processed by the server. Now changed that and the
3506 server processes all notify packets. After relaying the packet
3507 to the client the notify packet is processed in the server.
3509 * The silc_server_free_client_data now checks whether there is
3510 pending outgoing traffic for the client and purges the data to
3511 the network before removing the client entry.
3513 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3516 an client is killed from the SILC Network. Updated the protocol
3519 Added new function silc_server_send_notify_killed to the
3520 silcd/packet_send.[ch].
3522 * Added function silc_server_packet_relay_notify to relay notify
3523 packets that are destined directly to a client. In this case
3524 the server does not process the notify packets but merely relays
3525 it to the client. Affected file silcd/packet_send.[ch].
3527 Added also silc_server_packet_process_relay_notify to check
3528 whereto relay the notify. Affected file is
3529 silcd/packet_receive.[ch].
3531 * Implemented the KILL command to the server.
3535 * Added the backup schema desgined last fall to the protocol
3536 specs for everyone to see. The specification is in the
3537 *-spec-xx.txt draft and the packet type definitions for the
3538 backup routers is in *-pp-xx.txt draft. Thusly, added also
3539 new packet type SILC_PACKET_CELL_ROUTERS.
3541 * A big security problem in the implementation discovered. The
3542 signoff of an client did not cause new channel key generation
3543 which it of course should've done. The channel keys must be
3544 always re-generated when client leaves (or signoffs) the channel.
3545 The silc_server_remove_from_channels funtion now handles
3546 the channel key re-generation.
3548 * Added `sender' argument to the silc_server_send_notify_on_channels
3549 to not to send the client provided as argument. Affected file
3550 silcd/packet_send.[ch].
3552 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Implemented OPER and SILCOPER commands into the server and
3557 * Added silc_auth_verify and silc_auth_verify_data to verify
3558 the authentication directly from the authentication payload.
3559 It supports verifying both passphrase and public key based
3560 authentication. Affected file lib/silccore/silcauth.[ch].
3562 * Added `hash' field to the SilcIDListData structure. It is the
3563 hash negotiated in the SKE protocol. Affected file is
3566 * Slight redesigning of the SilcAuthPayload handling routines.
3567 Do not send SilcPKCS but SilcPublicKey as argument.
3569 * Implemented the public key authentication support to the
3570 serverconfig. The public key is loaded from the provided path
3571 and saved as authentication data to void * pointer. Thus,
3572 changed the unsigned char *auth_data to void *auth_data;
3574 * Fixed SHUTDOWN command to send the reply before the server
3575 is shutdown. :) Affected file silcd/command.c.
3577 * Fixed fatal bug in CONNECT command. The hostname was invalid
3578 memory and server crashed. Affected file silcd/command.c.
3580 * Fixed fatal bug in CLOSE command. The server_entry became
3581 invalid but was referenced later in the command. Affected file
3584 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Fixed fatal bug in failure packet handling. Server ignored
3587 the failure and thus crashed when it came.
3591 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3594 that the command may be executed only once in (about) 2 seconds.
3595 The old SILC_CF_LAG flag is same but allows command bursts up
3596 to five before limiting.
3598 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3599 server code. Various commands now includes the CF_LAG_STRICT
3600 flag to disallow any kind of miss-use of the command.
3602 * Fixed the silc_buffer_unformat to not to allocate any data
3603 if the length of the data is zero. It used to allocate the
3604 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3606 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * Changed the format of AdminConnection configuration section
3609 in the server. Added username of the admin to the format.
3610 Affected files silcd/serverconfig.[ch].
3612 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3613 to return admin configuration data by host, username and/or
3616 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Implemented WHOWAS command to the server. Added the functions:
3620 silc_server_command_whowas_parse,
3621 silc_server_command_whowas_send_reply,
3622 silc_server_command_whowas_from_client and
3623 silc_server_command_whowas_from_server
3625 * Added <Client ID> argument to the WHOWAS command reply. Updated
3626 the protocol specs accordingly.
3628 * Implemented WHOWAS command and command_reply to the client
3631 Implemented the WHOWAS printing on the user interface.
3633 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Added new argument to the WHOWAS command reply, the real name.
3636 It is an optional argument. Updated the protocol specs.
3638 * Added SilcIDCacheDestructor callback that is registered when
3639 the SilcIDCache is allocated. The callback is called when
3640 an cache entry in the ID Cache expires, or is purged from the
3641 cache. Added into lib/silccore/idcache.[ch].
3643 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3644 to destruct the client entries when the cache entry expires.
3645 Other ID Cache's in server and in the client library ignores
3648 * If the ID Cache entry's `expire' field is zero then the entry
3649 never expires. Added boolean `expire' argument to the
3650 silc_idcache_add function in the lib/silccore/idcache.[ch].
3651 If it is TRUE the default expiry value is used.
3653 * Added silc_server_free_client_data_timeout that is registered
3654 when client disconnects. By default for 5 minutes we preserve
3655 the client entry for history - for WHOWAS command.
3657 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Added support to the server to enforce that commands are not
3660 executed more than once in 2 seconds. If server receives
3661 commands from client more frequently, timeout is registered
3662 to process the commands. Affected file silcd/command.c.
3663 Added new function silc_server_command_process_timeout.
3665 * Changed NICK_NOTIFY handling in client library to check that
3666 if the client's nickname was changed, so there is no need to
3667 resolve anything from the server.
3669 * Removed error printing from the WHOIS and IDENTIFY commands.
3670 If error occurs then it is ignored silently in the client library.
3671 The application, however, may map the received error to
3672 human readable error string. The application currently maps
3673 the NO_SUCH_NICKNAME error to string.
3675 * Made the command status message public to the application. Moved
3676 them from lib/silcclient/command_reply.c to
3677 lib/silcclient/command_reply.h. The application can map the
3678 received command status to the string with the
3679 silc_client_command_status_message function.
3681 * Added check to the server to check that client's ID is same
3682 as the Source ID in the packet the client sent. They must
3685 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Added dist-bzip hook to the Makefile.am to make bzip2
3688 compressed distributions.
3690 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Server now enforces the maximum length for the nickname and
3693 the channel as protocol specification dictates. 128 bytes for
3694 nickname and 256 bytes for channel name.
3696 * Moved the WHOIS printing to the application. The client libary
3697 does not print out the WHOIS information anymore, the application
3698 must do it. Renamed silc_client_command_reply_whois_print to
3699 the silc_client_command_reply_whois_save.
3701 The client's idle time is also sent to the application now, and
3702 the idle is shown on screen.
3704 * Added silc_client_command_reply_identify_save to save the
3705 received IDENTIFY entries.
3707 * Do not check for channel private keys in message sending and
3708 reception if the channel does not have the PRIVKEY mode set.
3709 Affected file lib/silclient/client_channel.c.
3711 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3713 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3714 just surfaced after chaning the JOIN procedure.
3716 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Added silc_client_get_clients_by_list to get client entries
3719 from Client ID list, that is returned for example by JOIN
3720 and USERS command replies. The application should use this
3721 function for example when JOIN command reply is received to
3722 resolve the clients already on the channel (library does not
3723 do that anymore as USERS command reply is not used in the JOIN
3724 procedure anymore). Affected files lib/silcclient/silcapi.h and
3725 lib/silcclient/idlist.c.
3727 * JOIN command reply and USERS command reply returns now SilcBuffer
3728 pointers instead of unsigned char pointers when returning
3729 the client list and mode list.
3731 * Added <Client ID> argument to the JOIN command reply, mainly
3732 for the server to identify for which client the command was
3733 originally sent. Updated protocol specs accordingly.
3735 * Added SilcDlist private_key pointer to the SilcChannelEntry
3736 in the client to support the channel private keys. Affected
3737 file is lib/silcclient/idlist.h.
3739 * Added SilcChannelPrivateKey argument to the function
3740 silc_client_send_channel_message so that application can choose
3741 to use specific private ke if it wants to. If it is not provided,
3742 the normal channel key is used, unless private keys are set.
3743 In this case the first (key that was added first) is used
3744 as the encryption key.
3746 * Implemented the support for channel private key handling.
3747 Implemented the following functions:
3749 silc_client_add_channel_private_key,
3750 silc_client_del_channel_private_keys,
3751 silc_client_del_channel_private_key,
3752 silc_client_list_channel_private_keys and
3753 silc_client_free_channel_private_keys
3755 Affected file lib/silcclient/client_channel.c.
3757 * Added the support for the private keys in the channel message
3758 sending and encryption and in the message reception and
3759 decryption. Affected funtions are
3760 silc_client_send_channel_message and silc_client_channel_message.
3762 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Added SKE's key verify callback to the client library's
3765 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3767 * Removed the statement that server (or router) must send USERS
3768 command reply when joining to the channel so that the client
3769 knows who are on the channel. Instead, the client list and
3770 client's mode list is now sent in the JOIN command reply to the
3771 client who joined channel. This is better solution.
3773 * Added function silc_server_get_users_on_channel and function
3774 silc_server_save_users_on_channel to the silcd/server.[ch].
3776 * Removed function silc_server_command_send_users from the
3779 * Do not show topic on the client library anymore. The topic is
3780 sent in the command reply notify to the application and the
3781 application must show the topic now.
3783 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added client searching by nickname hash into the IDENTIFY and
3786 WHOIS commands in the server as they were clearly missing from
3787 them. Affected file is silcd/command.c.
3789 * Fixed a bug in private message receiving in the client library.
3790 The remote ID was freed and it wasn't supposed, now it is
3793 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Minor fix to the channel payload; allocate the data area, as it
3796 needs to be of specific length.
3798 * If the key agreement port is zero then the operating
3799 system will define the bound port. Affected files are
3800 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3802 * Added new function silc_channel_payload_decrypt into the file
3803 lib/silccore/silcchannel.[ch].
3805 * Moved the channel message etc, check from silc_packet_decrypt
3806 to applications. The library calls now a generic
3807 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3808 when the packet is either normal or special. This was done to
3809 allow more wide range of checking that was not allowed when
3810 the code was in library. Now applications can do virtually any
3811 checks to the packet and return to the library the decision how
3812 the packet should be processed. Affected files are
3813 lib/silccore/silcpacket.[ch].
3815 Added silc_server_packet_decrypt_check to the server and
3816 silc_client_packet_decrypt_check to the client library.
3818 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3819 to send with specified source and destination information.
3821 * Channel message delivery between routers was broken after the
3822 channel key distribution was fixed earlier. The channel key
3823 was used be to distributed to other routers as well which is not
3824 allowed by the protocol. Now this is fixed and channel keys
3825 really are cell specific and the channel message delivery between
3826 routers comply with the protocol specification.
3828 * Fixed various commands in server to check also the global list
3829 for the channel entry and not just the local list. The affected
3830 file silcd/command.c.
3832 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Added assert()s to buffer formatting and unformatting routines
3835 to assert (if --enable-debug) when error occurs. Affected
3836 file: lib/silcutil/silcbuffmt.c.
3838 * Changed to auto-reconnect to check whether the remote host is
3839 router and register the re-connect timeout if it is. It used
3840 to check that whether we are normal server, but router must do
3841 auto-reconnect with another router as well. Affected file
3844 * Removed the [<key len>] option from CMODE command as the cipher
3845 name decides the key length, nowadays. See the defined ciphers
3846 from the protocol specification.
3848 * Added [<hmac>] option to the CMODE command to define the HMAC
3849 for the channel. Added SILC_CMODE_HMAC channel mode.
3851 * Added [<hmac>] option for the JOIN command so that user can
3852 select which HMAC is used to compute the MACs of the channel
3855 * Added Hmac field to the Channel Message Payload. The integrity
3856 of plaintext channel messages are now protected by computing
3857 MAC of the message and attaching the MAC to the payload. The
3858 MAC is encrypted. Now, it is clear that this causes some
3859 overhead to the size of the packet but rationale for this is that
3860 now the receiver can verify whether the channel message decrypted
3861 correctly and also when private keys are set for the channel the
3862 receiver can decrypt the packet with several keys and check from
3863 the MAC which key decrypted the message correctly.
3865 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3866 lib/silccrypt/silccipher.[ch].
3868 * Added silc_hash_len to return the digest length into the
3869 lib/silcrypt/silchash.[ch].
3871 * Rewrote parts of Silc Channel Payload interface in the
3872 lib/silccore/silcchannel.[ch]. The encode function now also
3873 encrypts the packet and parse function decrypts it.
3875 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Fixed a minor formatting bug in the SKE's key material processing.
3878 It actually might have processed the keys wrong way resulting
3881 * Redefined the mandatory HMAC algorithms and added new algorithms.
3882 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3883 and hmac-md5 truncated to 96 bits. The mandatory is now
3884 hmac-sha1-96. Rest are optional (including the one that used
3885 to be mandatory). Rationale for this is that the truncated HMAC
3886 length is sufficient from security point of view and can actually
3887 make the attack against the HMAC harder. Also, the truncated
3888 HMAC causes less overhead to the packets. See the RFC2104 for
3891 * Added new [hmac] configuration section. The SKE used to use
3892 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3893 is of course wrong. The official names that must be proposed in
3894 the SKE are the ones defined in the protocol specification
3895 (hmac-sha1-96 for example). The user can configure any hmac
3896 using any hash function configured in the [hash] section. At
3897 least, the mandatory must be configured.
3899 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3901 * Added HMAC list to the SKE proposal list. It has now both
3902 hash algorithm list and HMAC list. This makes the protocol
3903 incompatible with previous versions. The SKE now seems to work
3904 the way it is supposed to work, for the first time actually.
3906 * Defined plain Hash algorithms to the protocol specification.
3909 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Implemented support for key agreement packets into the server.
3912 Added functions silc_server_key_agreement and
3913 silc_server_send_key_agreement. Other than these functions,
3914 server has nothing to do with this packet.
3916 * Added support for private message key packets into the server.
3917 Added functions silc_server_private_message_key and
3918 silc_server_send_private_message_key.
3922 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3923 called in the protocol's final callback instead in the END
3924 protocol state. This makes a little more sense and in the same
3925 time in client we can use the same protocol routines for normal
3926 key exchange and to key agreement packet handling as well.
3928 * Added to both client's and server's KE protocol context the
3929 SilcSKEKeyMaterial pointer to save the key material. We will
3930 bring the key material to the protocol's final callback by doing
3931 this. The final callback must free the key material.
3933 * Added SKE's packet_send callback into client's KE protocol
3934 context so that the caller can choose what packet sending function
3935 is used. This way we can use different packet sending when
3936 doing normal SKE when doing key agreement packet handling (in
3937 the key agreement packet handling we do not want to encrypt
3940 * Implemented the responder side of the key agreement routines
3941 in the client. The client can now bind to specified port and
3942 accept incoming key negotiation. The key material is passed
3943 to the application after the protocol is over.
3945 * Implemented the processing of incoming Key Agreement packet
3946 in the client. Added function silc_client_key_agreement to
3949 * Implemented the intiator side of the key agreement routines
3950 in the client. The client can now initiate key agreement with
3951 another remote client. The key material is passed to the
3952 application after the protocol is over.
3954 * Created client_keyagr.c to include all the key agreement
3957 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3958 SILC_TASK_CALLBACK except that it is not static.
3960 * Created client_notify.c and moved the Notify packet handling
3961 from the client.[ch] into that file.
3963 * Created client_prvmsg.c and moved all private message and
3964 private message key routines from the client.[ch] into that file.
3966 * Create client_channel.c and moved all channel message and
3967 channel private key routines from the client.[ch] into that file.
3969 * Changed silc_client_get_client_by_id_resolve to resolve with
3970 WHOIS command instead of IDENTIFY command, in the file
3971 lib/silclient/idlist.c.
3973 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Implemented the SKE's responder side to the Client library.
3977 * When FAILURE is received to the protocol do not trust it
3978 blindly. Register a timeout to wait whether the remote closes
3979 the connection as it should do it, only after that process the
3980 actual failure. This was changed to both client and server.
3982 * Added client_internal.h to include some of the structures
3983 there instead of client.h in lib/silcclient/.
3985 * Added function silc_task_unregister_by_callback to unregister
3986 timeouts by the callback function.
3988 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Some "Incomplete WHOIS info" errors has been appearing on the
3991 log files. Took away the entry->userinfo check from WHOIS
3992 reply sending. The entry->userinfo is now " " if client did not
3993 provide one. I thought this was fixed earlier but something
3994 is wrong still. Let's see if the error still appears.
3996 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Fixed a minor bug in the login when the channel key is
3999 re-generated in the server. It used to generate the key in
4000 wrong order and thus caused problems in the channel traffic.
4002 * Fixed a minor bug in channel key distsribution after
4003 KICK command. The key was not sent to the router even though
4006 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Added silc_ske_process_key_material_data as generic routine
4009 to process any key material as the SILC protocol dictates. The
4010 function is used by the actual SKE library but can be used by
4011 applications as well. This relates to the private message keys
4012 and the channel private keys since they must be processed the
4013 same way the normal SILC session keys. The protocol dictates
4014 this. Affected files: lib/silcske/silcske.[ch].
4016 Added also silc_ske_free_key_material to free the
4017 SilcSKEKeyMaterial structure.
4019 * Defined silc_cipher_set_key function to set the key for
4020 cipher without using the object's method function. The affected
4021 files: lib/silccrypt/silccipher.[ch].
4023 * Implemented silc silc_client_add_private_message_key,
4024 silc_client_add_private_message_key_ske,
4025 silc_client_del_private_message_key,
4026 silc_client_list_private_message_keys and
4027 silc_client_free_private_message_keys functions in the
4030 Added functions silc_client_send_private_message_key to send
4031 the Private Message Key payload and silc_client_private_message_key
4032 to handle incoming Private Message Key payload.
4034 * Added Cipher field to the Private Message Key payload to set
4035 the cipher to be used. If ignored, the default cipher defined
4036 in the SILC protocol (aes-256-cbc) is used.
4038 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Removed lib/silcclient/ops.h file.
4042 Redefined parts of the SILC Client Library API. Created new
4043 file silcapi.h that deprecates the ops.h file and defines the
4044 published Client Library API. Defined also private message key
4045 API and channel private key API into the file.
4047 This is the file that the application must include from the
4048 SILC Client Library. Other files need not be included by
4049 the application anymore.
4051 * Added new key_agreement client operation callback and also
4052 defined the Key Agreement library API for the application.
4054 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4057 is used by clients to request key negotiation between another
4058 client in the SILC network. If the negotiation is started it
4059 is performed using the SKE protocol. The result of the
4060 negotiation, the secret key material, can be used for example
4061 as private message key.
4063 Implemented the Key Agreement payload into the files
4064 lib/silccore/silauth.[ch].
4066 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Redefined ciphers for the SILC protocol. Added some new ciphers
4069 and defined the key lengths for the algorithms. Changed the
4070 code accordingly. The default key length is now 256 bits.
4072 * Fixed SKE key distribution function silc_ske_process_key_material
4073 when the key length is more than 128 bits. The default key
4074 length in SILC is now 256 bits.
4076 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4077 to indicate unsupported algorithm.
4079 * Renamed rijndael.c to aes.c and all functions as well.
4081 * Fixed a long standing channel key setting bug in client library.
4082 Weird that it has never surfaced before.
4084 * Fixed bug in channel deletion. If the entire channel is removed
4085 then it must also delete the references of the channel entry
4086 from the client's channel list as the client's channel entry and
4087 the channel's client entry share same memory.
4089 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Implemented CONNECT and SHUTDOWN commands in the client.
4093 * Implemented CLOSE command to the client.
4095 * Added the function silc_idlist_find_server_by_name into the
4096 files silcd/idlist.[ch].
4098 Added the function silc_idlist_find_server_by_conn into the
4099 files silcd/idlist.[ch].
4101 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * DIE command was renamed to SHUTDOWN. Updated the both code
4106 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4107 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4109 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4112 * Added function silc_server_create_connection function to create
4113 connection to remote router. My server implementation actually
4114 does not allow router to connect to normal server (it expects
4115 that normal server always initiates the connection to the router)
4116 so the CONNECT command is only good for connecting to another
4119 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4122 or some other client was kicked from the channel.
4124 Implemented the handling of the notify type to both client
4127 Implemented silc_server_send_notify_kicked to send the KICKED
4128 notify. It is used to send it to the server's primary router.
4130 * Implemented the KICK command into server and client.
4132 * Added `query' argument to the silc_idlist_get_client function
4133 to indicate whether to query the client from server or not if
4136 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4137 to indicate that the client is not channel founder.
4141 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Removed the rng context from SilcPacketContext structure and
4144 changed that the packet routine uses the Global RNG API.
4146 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Added support for quit message that client can "leave" on the
4149 channel when it quits the SILC. It is ditributed inside the
4150 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4152 Added silc_server_free_client_data that will take the
4153 signoff message as argument.
4155 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4157 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Updated parts of the protocol specification to keep it up
4162 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4165 payloads in one packet.
4167 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4168 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4169 use now the new List flag.
4171 * Also deprecated the following packet types: REPLACE_ID,
4172 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4174 * Added list support for Notify packet in server.
4176 * Added silc_server_send_notify_channel_change to send the
4177 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4178 the silc_server_send_replace_id.
4180 * Added silc_server_send_notify_nick_change to send the
4181 NICK_CHANGE notify type. Deprecates the function
4182 silc_server_send_replace_id.
4184 * Added silc_server_send_notify_join to send the JOIN notify type.
4185 Deprecates the function silc_server_send_new_channel_user.
4187 * Added silc_server_send_notify_leave to send LEAVE notify type.
4188 Deprecates the function silc_server_send_remove_channel_user.
4190 * Added silc_server_send_notify_cmode and
4191 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4192 types. Deprecates the silc_server_send_set_mode function.
4194 * Added SERVER_SIGNOFF notify type to indicate that server has
4195 quit. This means that all clients on the channel from that
4196 server will drop. This can be also used when netsplit happens.
4198 Deprecated REMOVE_ID packet type since it is not needed anymore
4201 Added silc_server_send_notify_server_signoff to send the
4202 SERVER_SIGNOFF notify type. Deprecates the function
4203 silc_server_send_remove_id.
4205 Added also silc_server_send_notify_signoff to send the
4206 SIGNOFF notify type.
4208 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4209 SILC protocol from this day on. Changed the protocol
4210 specification as well.
4212 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4213 notify type. It is used between routers to notify about
4214 topic changes on a channel.
4216 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4219 * Partly updated the protocol specification to comply with the
4220 changes now made. It is still though a bit outdated.
4222 * The JOIN notify type now takes one extra argument <Channel ID>.
4223 The packet used to be destined to the channel but now the
4224 JOIN type may be sent as list thus it is impossible to
4225 destine it to any specific channel. By adding this argument
4226 it is again possible.
4228 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added CREDITS file. The CHANGES and CREDITS file will appear
4231 in the distribution as well.
4233 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4236 types in the server's silcd/packet_receive.c.
4238 * Implemented CMODE and CUMODE to work in router environment.
4240 * Fixed minor encoding and decoding buglet from the
4241 lib/silccore/silcmode.c.
4243 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4246 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4248 * Changed all SilcConfigServer* and silc_config_server* to
4249 SilcServerConfig* and silc_server_config*, respectively.
4252 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Associated the ID (client or server ID) to the Authentication
4255 Payload to avoid any possibility of forging. Updated the
4256 protocol specification and the code accordingly.
4258 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * The RSA key length is now save to the RsaKey context in the
4261 key generation process in lib/silccrypt/rsa.c. The key length
4262 is now used to figure out the maximum size of the block allowed
4263 to be encrypted/signed.
4265 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4266 is equivalent to the silc_mp_mp2bin but does not allocate any
4269 * Changed silc_mp_mp2bin API to take length argument. If it is
4270 non-zero then the buffer is allocated that large. If zero, then
4271 the size is approximated using silc_mp_sizeinbase, which however
4274 * Created Global RNG API which is global RNG that application can
4275 initialize. After initializing, any routine anywhere in the
4276 code (including library) can use RNG without allocating a new
4277 RNG object. This was done to allow this sort of use of the
4278 RNG in code that has no chance to allocate RNG object. All
4279 applications currently allocate this and many routines in the
4280 library use this. Affected file lib/silccrypt/silcrng.[ch].
4282 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4283 it to use the Global RNG API.
4285 * Defined Authentication Payload into protocol specification that
4286 is used during SILC session to authenticate entities. It is
4287 used for example by client to authenticate itself to the server
4288 to obtain server operator privileges.
4290 Implemented this payload into the lib/silccore/silcauth.[ch].
4291 Implemented also routines for public key based authentication
4292 as the new protocol specification dictates.
4294 Moved definitions of different authentication methods from
4295 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4297 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4298 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4299 silc_pkcs_verify_with_hash functions into the file
4300 lib/silccrypt/silcpkcs.[ch].
4302 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * The client entry's userinfo pointer must be always valid.
4305 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4306 will fail since it requires the userinfo. Now, the userinfo
4307 is allocated as "" if actual userinfo does not exist. Actually,
4308 it must exist and it is totally Ok to drop client connections
4309 that does not announce the userinfo. However, we will make
4310 this workaround for now.
4312 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4313 to return the remote port by socket.
4315 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4318 SILC_SERVER_PENDING_EXEC and added an new macro
4319 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4320 data or when error occurs while processing the pending command.
4322 Added new argument `destructor' into silc_server_command_pending
4323 and to the SilcServerCommandPending object. This destructor is
4324 now called after calling the pending callback or if error occurs
4325 immediately. If error occurs the actual pending callback won't
4326 be called at all - only the destructor. The destructor may be
4327 NULL if destructor is not needed.
4329 All this applies for client library code as well. Similar
4330 changes were made there as well for the pending commands.
4332 In the client, the application must now allocate the
4333 SilcClientCommandContext with the silc_client_command_alloc
4336 * Added reference counter to the SilcServerCommandContext. Added
4337 function silc_server_command_alloc and silc_server_command_dup
4340 Same type of functions added to the client library for the same
4343 * Removed the cmd_ident from IDListData away since it is now
4344 global for all connections. It is the command identifier used
4345 in command sending and with pending commands. The affected file
4348 * Added reference counter to the SilcSocketConnection objecet to
4349 indicate the usage count of the object. The object won't be
4350 freed untill the reference counter hits zero. Currently only
4351 server uses this, and client ignores it. The client must be
4352 set to use this too later. The affected files are
4353 lib/silccore/silcsockconn.[ch]. Added also the function
4354 silc_socket_dup to increase the reference counter.
4356 This was mainly added because it is possible that the socket
4357 is removed underneath of pending command or other async
4358 operation. Now it won't be free'd and proper DISCONNECTING
4359 flags, etc. can be set to avoid sending data to connection that
4360 is not valid anymore.
4362 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4363 the connection. After that it sets SILC_SET_DISCONNECTED.
4364 It is, however, possible that the socket data is not still freed.
4365 The silc_server_packet_process now checks that data is not
4366 read or written to connection that is DISCONNECTED. The socket
4367 get's freed when the reference counter hits zero.
4369 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Changed the client operation API: channel_message operation's
4372 `sender' is now the client entry of the sender, not the nickname
4373 and the `channel' is the channel entry, not the channel name.
4375 In the private_message operation the `sender' is now also the
4376 client entry of the sender not the nickname.
4378 Affected file is lib/silcclient/ops.h and all applications
4379 using the client operations.
4381 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Moved the calling of ops->connect() from connect_to_server_final
4384 into receive_new_id functin since that is the point when the
4385 client is actually allowed to send traffic to network. The
4386 affected file is lib/silcclient/client.c.
4388 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4391 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4392 (if needs broadcasting) instead of broadcasting the packets one
4393 by one which would make a burst in the network traffic.
4395 * Added `broadcast' argument to the functions in silcd/server.[ch]
4396 silc_server_create_new_channel[_with_id] to indicate whether
4397 to send New Channel packet to primary router.
4399 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Added new function into the silcd/server.[ch] files:
4402 silc_server_create_new_channel_with_id to create new channel with
4403 already existing Channel ID.
4405 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4406 lib/silccore/silcpacket.h. This packet is used t send list of
4407 Set Mode payloads inside one packet. Server uses this to set
4408 the modes for the channels and clients on those channels, that it
4409 announced to the router when it connected to it. The protocol
4410 specification has been updated accordingly.
4412 * The silc_server_new_channel did not handle the packet coming
4413 from normal server as it normally does not send that. However,
4414 when it announces its channels it does send it. Implemented
4415 the support for that.
4417 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4418 into the file lib/silccore/id.h.
4420 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Fixed memory leaks in the functions silc_idlist_del_client,
4423 silc_idlist_del_channel and silc_idlist_del_server in the file
4424 silcd/idlist.c. All of those leaked like a sieve.
4426 * Fixed some small memory leaks in the client's function
4427 silc_client_notify_by_server.
4429 * Added functions into silcd/server.c: silc_server_announce_clients,
4430 silc_server_announce_channels and silc_server_announce_server.
4431 These functions are used by normal and router server to announce
4432 to its primary router about clients, channels and servers (when
4433 router) that we own. This is done after we've connected to the
4436 These functions effectively implements the following packet types:
4437 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4438 and SILC_PACKET_NEW_ID_LIST.
4440 * Added new functions into the silcd/packet_receive.[ch]:
4441 silc_server_new_id_list, silc_server_new_channel_list and
4442 silc_server_new_channel_user_list to handle the incoming
4443 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4445 * Added support of changing Channel ID in the function
4446 silc_server_replace_id. If the server that announces a channel
4447 to the router already exists in the router (with same name but
4448 with different Channel ID), router is responsible to send
4449 Replace ID packet to the server and force the server to change
4450 the Channel ID to the one router has.
4452 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4453 client that the Channel ID has been changed by the router. The
4454 normal server sends this to the client. Client must start using
4455 the new Channel ID as the channel's ID.
4457 Implemented handling of this new type into lib/silcclient/client.c
4458 into the function silc_client_notify_by_server.
4460 * Added new function silc_idlist_replace_channel_id into the files
4461 silcd/idlist.[ch] to replace the Channel ID.
4463 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * Call silc_server_command_identify_check always when processing
4466 the IDENTIFY command in silcd/command.c
4468 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4471 send keepalive packets. The packet can be sent by clients,
4472 servers and routers.
4474 Added function silc_socket_set_heartbeat into the file
4475 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4476 If not set, the heartbeat is not performed. The actual
4477 heartbeat is implemented in the low level socket connection
4478 library. However, application is responsible of actually
4481 Added silc_server_send_heartbeat to send the actual heartbeat
4482 packet into silcd/packet_send.[ch]. Server now performs
4483 keepalive with all connections.
4485 * Added silc_task_get_first function into lib/silcutil/silctask.c
4486 to return the timeout task with shortest timeout. There was a bug
4487 in task unregistration that caused problems. TODO has been
4488 updated to include that task system must be rewritten.
4490 * The client library will now resolve the client information when
4491 receiving JOIN notify from server for client that we know but
4492 have incomplete information.
4494 * Rewrote parts of silc_server_remove_from_channels and
4495 silc_server_remove_from_one_channel as they did not remove the
4496 channel in some circumstances even though they should've.
4498 * Encryption problem encountered in server:
4500 The LEAVE command used to send the Channel Key packet to the
4501 router immediately after generating it. However, the code
4502 had earlier sent Remove Channel user packet but not immediately,
4503 ie. it was put to queue. The order of packets in the router
4504 was that Channel Key packet was first and Remove Channel User
4505 packet was second, even though they were encrypted in the
4506 reverse order. For this reason, MAC check failed. Now, this
4507 is fixed by not sending the Channel Key packet immediately but
4508 putting it to queue. However, this is more fundamental problem:
4509 packets that are in queue should actually not be encrypted
4510 because packets that are sent immediately gets encrypted
4511 actually with wrong IV (and thus MAC check fails). So, packets
4512 that are in queue should be encrypted when they are sent to
4513 the wire and not when they put to the queue.
4515 However, the problem is that the current system has not been
4516 designed to work that way. Instead, the packet is encrypted
4517 as soon as possible and left to the queue. The queue is then
4518 just purged into wire. There won't be any fixes for this
4519 any time soon. So, the current semantic for packet sending
4522 o If you send packet to remote host and do not force the send
4523 (the packet will be in queue) then all subsequent packets to the
4524 same remote host must also be put to the queue. Only after the
4525 queue has been purged is it safe again to force the packet
4528 o If you send all packets immediately then it safe to send
4529 any of subsequent packets through the queue, however, after
4530 the first packet is put to queue then any subsequent packets
4531 must also be put to the queue.
4533 Follow these rules and everything works fine.
4535 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Added new function silc_server_remove_clients_by_server to
4538 remove all client entries from ID list when the server connection
4539 is lost. In this case it is also important to invalidate all
4540 client entires as they hold the invalid server entry. This
4541 fixes fatal bug when server has lost connection and will reconnect
4544 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Made some sanity checks to silc_server_daemonise like to check
4547 whether the requested user and group actually exists.
4549 * Added sanity check to SKE's silc_ske_responder_finish to check
4550 that the public and private key actually is valid.
4552 * Invalidate the client's nickname when receiving Replace ID
4553 packet and the Client ID is being replaced. This means that the
4554 server will query the nickname if someone needs it (client)
4557 * Sort the ID Cache in client library when the ID Cache data
4558 has changed (needs sorting).
4560 * Do not allow for SILC client to create several connections to
4561 several servers. The client does not support windows right now
4562 and generating multiple connections causes weird behaviour.
4564 Irssi-silc client does support windows and can handle several
4565 connections without problems, see: www.irssi.org and SILC plugin.
4567 * Fixed some places where client was added to the IDList. The
4568 rule of thumb is following (in order to get everything right):
4569 If the client is directly connected local client then the
4570 `connection' argument must be set and `router' argument must be
4571 NULL to silc_idlist_add_client function. If the client is not
4572 directly connected client then the `router' argument must
4573 bet set and the `connection' argument must be NULL to the
4574 silc_idlist_add_client function.
4576 * The funtion silc_server_packet_send_local_channel actually did
4577 not check whether the client was locally connected or not. It
4578 does that now. Fixed a bug related to LEAVE command.
4580 * Fixed Remove Channel User payload parsing bug in server's
4581 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4583 * The server's silc_server_save_channel_key now checks also the
4584 global ID list for the channel as it might not be in the local
4585 list. Fixed a bug related to LEAVE command.
4587 * Is this the end of the [<unknown>] buglet that has been lurking
4588 around for a long time? A little for loop fix in server's
4589 silc_server_command_whois_parse that is used by both IDENTIFY
4590 and WHOIS command. At least, this was a clear bug and a cause
4591 of one type of [<unknown>] buglet.
4593 * WHOIS and IDENTIFY commands call the function
4594 silc_server_command_[whois/identify]_check function even if
4595 we are not router server.
4597 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Added --with-gmp configuration option. If set the GMP
4600 is always compiled in the SILC source tree. If not set then
4601 it is checked whether the system has the GMP3 installed. If
4602 it has then the GMP won't be compiled (the system's headers
4603 and library is used), if it doesn't have it then the GMP is
4604 compiled in the SILC source tree.
4606 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Changed RSA private exponent generation to what PKCS #1
4609 suggests. We try to find the smallest possible d by doing
4610 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4611 not security fix but optimization.
4613 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Added new config entry [Identity] to fork the server and run
4616 it as specific user and group. A patch from Bostik.
4618 * Imported Dotconf configuration library into lib/dotconf.
4619 This will be used to create the SILC configuration files later.
4620 It will appear in the distsribution after this commit.
4622 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * A big code auditing weekend happening. Auditing code for
4625 obvious mistakes, bugs and errors. Also, removing any code
4628 Removed files for being obsolete:
4630 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4631 inline in the file lib/silcutil/silcbuffer.h)
4633 o lib/silcutil/silcbufutil.c (the header has inline versions)
4635 Changed code to fix possible error conditions:
4637 o The buffer formatting routines now check that the destination
4638 buffer really has enough space to add the data. This applies for
4639 both buffer formatting and unformatting
4640 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4641 unformatting was changed to accomodate following rules:
4642 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4643 sent to the function while XXX_*STRING will not allocate or copy
4644 the data into the buffer. Instead it sets the pointer from the
4645 buffer into the pointer sent as argument (XXX_*STRING used to
4646 require that the pointer must be allocated already). This change
4647 makes this whole thing a bit more consistent and more optimized
4648 (note that the data returned in the unformatting with XXX_*STRING
4649 must not be freed now). The routines return now -1 on error.
4651 o Tried to find all code that use buffer_format and buffer_unformat
4652 and added return value checking to prevent formatting and
4653 especially unformatting errors and possible subsequent fatal
4656 o Changed ske->x and ske->KEY to mallocated pointers in
4657 lib/silcske/silcske.h. Fixed possible data and memory leak.
4659 o Added return value checking to all *_parse* functions. Fixed
4660 many memory leaks as well.
4662 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4663 so that buffer overflows would not happen. All code now also
4664 checks the return value as it can fail.
4666 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Added reconnection support to server if the normal server looses
4669 its connection to the router (for example if router is rebooted).
4670 The server performs normal reconnection strategy implemented
4671 to the server. Affected file silcd/server.c.
4673 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Added new packet type SILC_PACKET_SET_MODE that is used to
4676 distribute the information about changed modes (for clients,
4677 channels and clients channel modes) to all routers in the
4678 network. Updated the protocol specification accordingly.
4680 Added functions into silcd/packet_send.c and
4681 silcd/packet_receive.c: silc_server_send_set_mode,
4682 silc_server_set_mode.
4684 Added new files silcmode.[ch] into lib/silccore that implements
4685 the encoding and decoding of Set Mode Payload. Added new type
4686 SilcSetModePayload. Moved the definitions of different modes
4687 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4689 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Oops, a little mistake in server's connection authentication
4692 protocol. The protocol is not ended with FAILURE but with
4693 SUCCESS if the authentication is Ok. :) Affected file is
4696 * Implemented NICK_CHANGE notify handling in server in the file
4697 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4698 the local clients on the channel. After the changing nickname
4699 in router environment snhould work and the [<unknown>] nickname
4700 should appear no more.
4702 The silc_server_replace_id function that receives the Replace ID
4703 payload now sends the NICK_CHANGE notify type also in the file
4704 silcd/packet_receive.c
4706 * Changed WHOIS and IDENTIFY command to support the maximum amount
4707 of arguments defined in protocol specs (3328 arguments). This
4708 fixed a bug that caused problems when there were more than three
4711 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * Added extra parameter, command identifier, to the
4714 silc_client_send_command so that explicit command identifier
4717 Changed that ID list routines uses specific command identifier
4718 when sending WHOIS/IDENTIFY requests to the server so that they
4719 can be identified when the reply comes back.
4721 Affected files lib/silcclient/command.[ch],
4722 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4724 * Added `sender' argument to silc_server_packet_send_to_channel
4725 to indicaet the sender who originally sent the packet to us
4726 that we are now re-sending. Ignored if NULL. Affected file
4727 silcd/packet_send.[ch].
4729 * Added some server statistics support in silcd/server_internal.h
4730 SilcServerStatistics structure and around the server code. Also
4731 send some nice statistics information when client is connecting
4734 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Fixed channel ID decoding in server's JOIN command reply in
4737 silcd/command_reply.c
4739 * Fixed braodcasting of replace ID payload to not to send it if
4740 we are standalone server in silcd/packet_receive.c.
4742 * Fixed all channel message sending routines to not to send
4743 packets to clients that has router set, since they are routed
4744 separately in the same function earlier. Affects file
4745 silcd/packet_send.c and all channel packet sending functions.
4747 * In USERS reply, res_argv[i] are not allocated, the table
4748 is allocated. Thus changed that free the table, not its
4751 * In server's whois_check and identify_check if the client is
4752 locally connected do not send any WHOIS commands - they are not
4755 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Fixed some minor bugs in client when sending WHOIS command. The
4758 arguments was in wrong order.
4760 * Removed statis function add_to_channel from server in
4761 silcd/command.c that was previously used with the joining but
4764 * Tested USERS command in router environment successfully with two
4765 routers, two servers and two clients.
4767 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Reorganized the USERS command and command reply in client library
4770 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4771 When the command is given by user we register a pending command
4772 callback that will reprocess the command after the reply has been
4773 received from the server. When reprocessing the packet we then
4774 display the information. Thus, the USERS information is displayed
4775 now in the command callback instead of in the command reply
4776 callback. The processing of the command is same as previously
4777 when server has sent the command reply in the JOINing process.
4779 * Added to USERS command in silcd/command_reply.c to join the client,
4780 we didn't use to know about, to the channel after we've created
4781 a client entry for it. Also, for clienet we did know already still
4782 check whether it is on the channel or not and add it if not.
4784 * Removed silc_server_command_join_notify as the function and its
4787 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Changed the client's pending command handling to the same as the
4790 server's pending command handling. It is also now possible to
4791 execute command reply functions from other command reply
4792 function as the function callbacks for commands and command
4793 replies are one and same. The pending commands are not static
4794 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4795 in client connection context. Thus, pending commands are server
4796 connection specific as it is convenient.
4798 Changed the function silc_client_command_pending and
4799 silc_client_command_pending_del and added new function
4800 silc_client_command_pending_check. Removed the
4801 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4804 * Added cmd_ident, current command identifier, to the client
4805 connection context in lib/silcclient/client.h to keep track on
4806 command identifiers used in command sending. Client's command reply
4807 function handling now supports the mandatory command identifiers.
4809 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4810 funtions in client to fully support pending command callbacks.
4812 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4813 as one of the arguments to the application in the command reply
4816 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4817 before first releasing SILC but came back. Now it is removed again
4818 and should come back nomore. The FORWARDED flag was used only
4819 by the JOINing procedure by forwarding the command packet to router.
4820 Now, the JOINing procedure has been changed to more generic (due
4821 to various router environment issues) and FORWARDED is not needed
4822 anymore for anything. The protocol specification is yet to be
4825 Now, removed silc_server_packet_forward from server and the flag
4826 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4828 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Renamed NAMES command to USERS command. The NAMES was named that
4831 due to historical reasons. Now it is renamed. Also, rewrote
4832 parts of the USERS command. The nickname list is not sent anymore
4833 by the server. Only Client ID and mode lists are sent in the USERS
4834 command. Changed this also to the protocol specification.
4836 The client now resolves the names and stuff after it receives
4837 the USERS list from the server when joining to the channel.
4839 * WHOIS and IDENTIFY commands has been changed to support multiple
4840 Client ID's per command. One can now search for multiple users
4841 in the network by sending only one WHOIS or IDENTIFY command.
4842 Changed the code and the protocol specifications.
4844 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4845 uses silc_server_command_whois_parse to parse the request. */
4847 * If normal server, do not parse the WHOIS and IDENTIFY requests
4848 before sending it to the router. Saves some time.
4850 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Fixed JOIN command on client library. Wrong number of arguments
4853 used to crash the client.
4855 * Added silc_server_channel_has_global function to check whether
4856 channel has global users or not.
4858 * Added silc_server_channel_has_local function to check whether channel
4859 has locally connected clients on the channel.
4861 * The silc_server_remove_from_one_channel now checks whether the
4862 channel has global users or not after given client was removed from
4863 the channel. It also checks whether the channel has local clients
4864 on the channel anymore. If it does not have then the channel entry
4865 is removed as it is not needed anymore.
4867 * The silc_server_notify now checks on JOIN notify whether the joining
4868 client is one of locally connected or global. If it is global then
4869 the channel has now global users on the channel and that is marked
4870 to the channel entry. Also, it now saves the global client to
4871 global list who is joining and JOINs it to the channel. This is
4872 for normal server, that is.
4874 Changed silc_server_send_notify_on_channel,
4875 silc_server_packet_relay_to_channel and
4876 silc_server_packet_send_to_channel check if we are normal server
4877 and client has router set (ie. global client) do not send the
4878 message to that client, as it is already routed to our router.
4880 * Implemented LEAVE notify type handling in silc_server_notify
4883 * Tested LEAVE command in router environment successfully. Tested
4884 with two routers, two servers and two clients.
4888 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4890 * Implemented SIGNOFF notify type handling in silc_server_notify
4893 * silc_server_remove_id now removes the client entry from all channels
4894 it has joined and thusly sends SIGNOFF notify type.
4896 * Rewrote the NAMES list generation in server by removing two excess
4897 loops. The lists are created now inside one loop.
4899 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * silc_server_remove_channel_user checks now also global list
4902 for channel and client.
4904 * silc_server_new_channel_user checks now both local and global
4905 list for channel and client. Fixed a bug in client id decoding.
4906 Used to decode wrong buffer.
4908 * silc_server_channel_message checks now both local and global
4909 list for channel entry.
4911 * Tested channel joining (hence JOIN) in router environment
4912 successfully. Tested with two routers, two servers and two
4915 * Tested channel message sending in router environment successfully.
4917 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Added silc_server_save_channel_key into server.[ch] to save the
4920 received channel key in Channel Key payload processing. It is
4921 also used in JOIN command reply handling.
4923 Equivalent function silc_client_save_channel_key added into
4924 client.[ch] into client library.
4926 * Changed JOIN command reply to send information whether the channel
4927 was created or not (is existing already) and the channel key
4928 payload. Changed protocol specs accordingly.
4930 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4931 the request was sent by ID and not by nickname. Crashed on
4934 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4937 now correctly save the received data.
4939 * silc_server_free_sock_user_data now notifies routers in the
4940 network about entities leaving the network.
4942 At the same time implemented functions silc_server_remove_id
4943 and silc_server_send_remove_id to receive and send REMOVE_ID
4944 packets. The packet is used to notify routers in the network
4945 about leaving entities. The ID removed will become invalid in
4948 * Added function silc_idlist_del_server into server. Removes and
4949 free's server entry from ID list.
4951 * silc_server_private_message function now checks, if we are router,
4952 that the destination ID really is valid ID, naturally.
4954 * In router when NEW_ID packet is received (for new client) the
4955 hash of the Client ID is saved in the ID Cache but the
4956 client->nickname is set to NULL, instead of putting the hash
4959 IDENTIFY command now also checks that client->nickname must be
4960 valid. If it is not if will request the data from the server who
4961 owns the client. Added new function
4962 silc_server_command_identify_check.
4964 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4965 to set the command to already allocated Command Payload.
4967 * Tested private message sending in router environment with two
4968 routers, two servers and two clients. Fixed minor bugs and now
4971 * Fixed segfault from client's NAMES command. Used to crash if
4974 * Forwarded packets must not be routed even if it is not destined
4975 to the receiver. Changed server code comply with this.
4977 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Added `require_reverse_mapping' boolean value to ServerParams
4980 structure. If TRUE (not default) the server will require that
4981 the connecting host has fully qualified domain name.
4983 If the reverse mapping is not required and hostname could not be
4984 found the IP address is used as hostname.
4986 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Implemented version string checking to both client and server.
4989 The check is incomplete currently due to the abnormal version
4990 strings used in development version of SILC.
4992 * Changed all command functions in server to use the new
4995 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Changed char *data to unsigned char *data in ID Cache system to
4998 support binary data as ID Cache data. Changed code to support
4999 binary data in lib/silccore/idcache.c.
5001 * Renamed silc_server_packet_relay_command_reply to
5002 silc_server_command_reply as it is normal packet receiving
5003 function. Rewrote the function to accept command replys for
5004 servers and not only for clients.
5006 * Mark remote router always as registered server if we are connecting
5007 to it. Otherwise, commands sent by the router to us are ignored.
5009 * All ID List find routines now returns the ID Cache Entry pointer
5010 as well if requested.
5012 * WHOIS command works now in router environment, tested with two
5013 routers, two servers and two clients.
5015 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5016 in router environment (as it is almost equivalent to WHOIS) but
5017 hasn't been tested thoroughly. Added new functions:
5019 silc_server_command_identify_parse
5020 silc_server_command_identify_send_reply
5021 silc_server_command_identify_from_client
5022 silc_server_command_identify_from_server
5024 * Disabled route cache adding because adding two different ID's with
5025 same IP replaces the old cache entry thus giving wrong route.
5026 The entry->router->connection is always the fastest route anyway
5027 so route cache may not be needed. Of course, new routes maybe
5028 established after receiving the ID when the entry->router->connection
5029 might not be anymore the most optimal.
5031 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Add route cache for received ID for fast routing.
5035 * Added silc_server_packet_route to route received packet on router
5036 that is not destined to us.
5038 * Renamed silc_server_get_route to silc_server_route_get.
5040 * Added id_string and id_string_len fields into SilcServer to
5041 include encoded ServerID for fast comparing without excess
5042 encoding of the ID's.
5044 * Cleaned up WHOIS command on server side. Added following static
5047 silc_server_command_whois_parse
5048 silc_server_command_whois_check
5049 silc_server_command_whois_send_reply
5050 silc_server_command_whois_from_client
5051 silc_server_command_whois_from_server
5053 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5054 arguments in command replies. All command functions should be
5055 updated to use this macro.
5057 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Minor typo fixes on command reply handling on server.
5061 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Added silc_server_command_add_to_channel internal routine to add
5064 the client to the channel after router has created the channel and
5065 sent command reply to the server.
5067 * Added generic silc_server_send_command to send any command from
5070 * Use static buffer with ID rendering instead of duplicating data.
5072 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Fixed a channel user mode bug when joining to a channel server gave
5075 everybody channel founder rights, oops.
5077 * We mark ourselves as the router of the incoming server connection
5078 if we are router ourselves. This way we can check in some packet
5079 sending functions whether it is locally connected server. For
5080 incoming router connections we put NULL.
5082 * For router sending packets locally means now always sending the
5083 packet cell wide; to local clients and local servers. For normal
5084 server sending packet locally means sending it to only local
5087 * Fixed the JOIN command to really work in router environment. If the
5088 channel is created it is always created by the router. Router is
5089 also responsible of making the initial joining to the channel,
5090 sending JOIN notify to the sending server and distributing
5091 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5092 does not exist server doesn't do anything else but forward the
5093 command to the router which performs everything.
5095 * Added silc_server_send_channel_key function to send the Channel Key
5098 * Added silc_server_create_channel_key to create new channel key. The
5099 channel key is now re-generated everytime someone joins or leaves
5100 a channel, as protocol dictates. Note: channel->key_len is the
5103 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5106 packet_receive.[ch] to separate packet sending and receiving
5107 routines. The server.[ch] now includes everything else including
5108 actual packet processing (writing and reading data) and other
5111 Renamed silc_server_private_message_send_internal to
5112 silc_server_send_private_message. The routine is still though
5113 used only to relay private messages as server does not send
5114 private messages itself.
5116 Renamed silc_server_new_channel to silc_server_create_new_channel
5117 and added new function sicl_server_new_channel that handles the
5118 incoming New Channel packet. Added also new sending function
5119 silc_server_send_new_channel to send New Channel Payload.
5121 * Added new function silc_server_notify to process incoming notify
5122 packet to the server/router. Server may then relay the notify
5123 to clients if needed.
5125 * Added new function silc_server_new_channel_user to process incoming
5126 New Channel User packet. Router will redistribute the packet and
5127 send JOIN notify to its local clients and locally connected servers
5128 if needed. Normal server will send JOIN notify to its local client
5129 on same channel when received this packet. Added also corresponding
5130 sending function silc_server_send_new_channel_user to sent the
5133 * Added boolean route argument to send_notif_to_channel and
5134 packet_send_to_channel functions to attempt to route the packet
5135 if it is TRUE and send only locally if it is FALSE.
5137 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * silc_server_replace_id now broadcasts the received replace ID
5140 packet if it is not broadcast packet already. The router must
5141 broadcast to inform other routers about changed ID.
5143 * Added backpointer to server's router into SilcServer context in
5144 silcd/server_internal.h.
5146 * Fixed silc_server_packet_broadcast to send correct broadcast
5149 * The channel key is now distributed to the local client as soon
5150 as it is received from the router (in router environment) so that
5151 no other packet may be sent for the channel until client has
5154 * silc_server_remove_channel_user now broadcasts the received
5155 Remove Channel User packet if it is not broadcast packet already.
5156 The router must broadcast to inform other routers about removed
5159 * Added users field into SilcPacketContext that is a reference count
5160 of the context. One can increase the reference count by calling
5161 silc_packet_context_dup which is now changed to just increase the
5162 reference count instead of duplicating the data. The reference
5163 count is decresed by calling silc_packet_context_free that will
5164 free the data after the reference count hits zero.
5166 For now on the packet context and everything allocated into it
5167 (including the raw packet from network) must be freed by calling
5168 the new silc_packet_context_free function. Added also new function
5169 silc_packet_context_alloc that must be used now to allocate the
5170 context. This also means that if a routine is asynchronous from
5171 silc_[client/server]_packet_parse_type the packet context must
5172 be duplicated by calling silc_packet_context_dup. Otherwise it
5173 gets free'd after silc_[client/server]_packet_parse_type returns.
5174 Also, one must remember that if packet is duplicated then its
5175 reference count must be decresed by calling the free function as
5176 many times as it was duplicated.
5178 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5179 from both client and server.
5181 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Made joining to a channel working in router environment.
5185 * Cleaned up JOIN command on server side and create function
5186 silc_server_command_join_channel internal routine to make the
5189 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Changed silc_command_pending list to SilcDList. Also, added
5192 `ident' field to SilcServerCommandPending structure to identify
5193 the reply and to call correct callback.
5195 Added silc_server_command_pending_check function to replace the
5196 corresnponding macro. The silc_command_pending list is not
5199 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5200 to set identifier to previously allocated Command Payload. It
5201 is used to set identifier for command when resending Command
5204 * Added silc_command_payload_encode_payload to encode Command
5205 Payload buffer from SilcCommandPayload structure.
5207 * Added silc_argument_payload_encode_payload to encode Argument
5208 payload buffer from SilcArgumentPayload structure.
5210 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Changed WHOIS command to support router connection on server side.
5213 The whois request is always sent to router unless the server is
5214 standalone server. After server has received the reply from the
5215 router will it send the reply to the client.
5217 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5218 broadcast received broadcast packet. The function is used only
5219 by router. The broadcast packet is always sent to the router's
5222 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5223 render given ID to printable string, for log files for example.
5225 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Made basic router to router connections working. At least they
5228 can now connect to each other but nothing really works the way
5229 they are supposed - yet.
5231 * Added new initiator token to RouterConnection configuration
5232 file in silcd/serverconfig.[ch]. It is used to tell whether we
5233 are the initiator to the remote router or whether we'll expect
5234 the other end to connect.
5236 * Moved registering of listener task to silc_server_init, hence
5237 the server starts listenning as soon as it is run, even if it
5238 does not have connections to other routers. Let's see how well
5241 * Changed default connection retry timeouts for more suitable in
5244 * Removed cipher and such arguments from silc_idlist_add_client
5245 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5246 Added new function silc_idlist_add_data to add the keys and stuff
5249 * Added SilcIDListData structure and added it to SilcClientEntry
5250 and SilcServerEntry as their first field in the structure. This
5251 way we can explicitly cast the ID entries to the SilcIDListData
5252 structure and get common data for the entries. In past, we had
5253 to first check what type of connection it is and then cast it to
5254 correct ID entry type. Now, we can directly cast the opaque
5255 pointer to the SilcIDListData (no matter what ID entry it actually
5256 is) and get the data needed.
5258 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5261 in some circumstances even if threre were timeout tasks, though not
5262 IO tasks, but tasks anyway. Now fixed.
5264 * Defined SilcServerConnection structure to hold connection specific
5265 stuff about directly connected servers and routers. The definition
5266 is currently in silcd/server_internal.h. I thought about having
5267 a bit more important role fro this struct but for now it is used
5268 only when connecting to other server (or router actually).
5270 * Added connecting retry support in server when connecting to
5271 router(s). The retry feature implement exponential backoff
5272 algorithm. Also, added SilcServerParams structure to hold default
5273 parameters for server. For now, it include these retry settings
5274 and are hard coded. After server is moded to be as Silc Server
5275 Library this structure will be more important.
5277 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Changed client librarys channel->clients table to SilcList and
5280 changed code accordingly.
5282 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Changed client's channel table to SilcList and changed code
5285 accordingly. Also changed SilcChannelClientEntry to include back-
5286 pointer to the channel so that client entry can use that structure
5287 as list as well and we have fast cross-reference to the channel.
5288 This change dramatically decreased the complexity of channel
5289 handling with client entry and vice versa (removed one extra
5290 loop when searching for channel entry from many functions).
5292 * Changed server->sim from table to SilcDList and changed code
5295 * NAMES command can now be used from user interface. It will show
5296 the user list on the channel, neatly.
5298 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5299 Code now saves realname of the user if it becomes available.
5301 * Renamed configure.in to configure.in.pre and made ./prepare
5302 script to automatically add correct version string to
5303 configure.in which it creates from configure.in.pre.
5305 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * NAMES command reply now shows users mode with the nickname when
5310 * Moved silc_client_ch[u]mode[_char] functions from
5311 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5312 place sucks, they are utility functions and should be in some
5315 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5317 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5320 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Added TRQ (efficient deque and list library) into lib/trq. This is
5325 a very good list library that is currently used in the SILC. Defined
5326 SilcList API over the library because I didn't like the API very
5327 much. See lib/trq/silclist.h for the API and examples of how to
5328 use the API. Fixed various places in the code to use the new
5329 SilcList API. The SilcList is meant for lists that has a structure
5330 already defined as a list. It is not suitable to add just some
5331 context to the list (in TRQ, the context is the list actually).
5333 So, I defined SilcDList that can be used for the purpose where
5334 predefined list structure does not exit. This can be used as
5335 such list. Now some context just can be added to the SilcDList.
5336 Currently this list is not used in the SILC just yet, though there
5337 are a lot places where this can replace dynamically allocated
5338 tables and I will fix these places, later, to use SilcDList.
5339 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5340 and use TRQ internally).
5342 Also fixed some annoying warning messages that the original TRQ
5343 code generated. Also minor changes to TRQ's Makefile.in.
5345 * Added support for querying by Client ID to both WHOIS and
5346 IDENTIFY commands into server, as required by the protocol.
5348 * Removed method function pointers from SilcBuffer structure. They
5349 weren't used to anything and just increased the context size for
5350 no good reason. This change also made silc_buffer_alloc and
5351 silc_buffer_free functions inline functions.
5353 * Disabled command flooding detection support until it's fixed so
5354 that it accepts commands in but does not execute them more than once
5357 * Added silc_net_localhost(), to return local hostname, into
5358 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5359 that must be initialized before calling silc_client_init.
5361 * Added new function: silc_server_send_notify_on_channels to send
5362 notify messages to all channels client has joined. It is assured
5363 that the message is sent only once per client.
5365 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5366 lib/silcutil/silcutil.[ch] as silc_format function. The new
5367 function is generic and is used by server as well, not only by
5368 the logging routines.
5370 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5371 the provided version string was not acceptable. Added new function:
5372 silc_ske_check_version into lib/silcske/silcske.h. The function
5373 must be implemented by the application (client or server) and it
5374 does not reside in the SKE library. The function checks the version
5375 string remote end sent.
5377 * Added back pointers (to opaque context and to SilcSocketConnection)
5378 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5380 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5381 duplicate packet context structure.
5383 * Changed `notify' client operation to send same arguments as client
5384 receives from server except for ID's. ID's are mapped to correct
5385 ID entry and that is returned. Also, if channel entry is not sent
5386 by server but the notify is for channel the channel entry is sent
5387 to application (otherwise application doesn't know that it is for
5388 channel (library gets it from packet's Destination ID)).
5390 * Added silc_client_remove_from_channels into client library to
5391 remove a client from all channels it has joined to. Used when
5392 received SIGNOFF notify from server. Added also new function
5393 silc_client_replace_from_channels to replace old ID entry with
5394 new ID entry on all channels. Used when received NICK_CHANGE
5397 * Fixed ID Cache list handling in silc_idlist_get_client in
5398 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5399 to get (or query) client by ID.
5401 * Updated TODO list.
5403 * Added connection authentication status message defined by the
5404 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5405 support for these into the code in client and server side.
5407 * Added generic function silc_client_send_command to send any command
5408 with variable argument list. Application should use this function
5409 to send commands if the command functions provided by the library
5410 does not suite for the application's user interface needs.
5412 * Added new `failure' client operation. Application is notified about
5413 received failure packet if client is executing a protocol. In this
5414 case the protocol's execution has failed.
5416 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5417 is required by the protocol.
5419 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5420 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5423 * Added status flag to SilcSKE object to indicate realtime status
5424 of the SKE protocol.
5426 * Application receives now exactly same command reply arguments as
5427 the library receives from server. However, if ID is received the
5428 corresponding ID entry is returned to the application (eg. Client
5429 ID is mapped to correct SilcClientEntry entry and that is returned).
5430 Changed command_reply client operation due to this change.
5432 * Changed all ID's in commands and in command replys as ID Payloads.
5433 Change affected both client and server side codes.
5435 All ID's sent in SILC network (with execption of ID's in SILC
5436 Packet header) are sent in ID Payload to support variable length
5439 * Server now notifies nick changes and notifies all clients on
5440 the channels about the new nickname (about the new Client ID,
5443 * Implemented CMODE command to change channel modes. Supports all
5444 channel modes defined by the protocol specs except ban and invite
5445 lists. (Also, private channel key mode is supported but support for
5446 setting private channel key in client is missing, thus, this mode
5447 has no effect on client side (except that server requires that the
5448 client uses private channel key and normal channel traffic does not
5451 Also, invite mode works per se, but INVITE command does not work
5452 yet correctly, so you can set channel as invite only channel but
5453 inviting clients to the channel does not work (it is yet to be
5454 thought what's the best way to do it).
5456 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5457 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5458 Implemented CUMODE command to change user's mode on the channel.
5459 Supports all modes defined by the protocol specs.
5461 * Added NAMES command reply to return users modes on the channel.
5463 * Removed unnecessary and slow ciphers from lib/silccrypt.
5465 * Set SO_KEEPALIVE option to connection sockets by default.
5467 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5469 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5470 redefined the Notify Payload into protocol specs.
5472 * Added silc_id_payload_parse_id to get ID directly from raw
5475 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5478 accept searching by Client ID as well.
5480 * Added support for LEAVE and SIGNOFF notify types in client library.
5482 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5483 to parse ID Payload from raw data.
5485 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Added flags parameter into silc_ske_assemble_security_properties
5488 function in lib/silcske/silcske.[ch].
5490 * Changed notify client operation to fit better for notify messages
5491 sent by server. The notify payload received from server is now
5492 passed to the application (after parsing it to SilcNotifyPayload).
5493 It is application's responsibility to retrieve the arguments
5494 from the payload and show the message the way it wants. The message
5495 sent by server is implementation specific.
5497 * Changed public keys to comply with the protocol specification.
5498 Old public keys are not supported anymore and are not compatible.
5500 * Removed nickname from Channel Payload as the latest draft removed
5501 it. The client must resolve the nickname from the NAMES command
5502 reply received when it joined the channel.
5504 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5506 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Fixed some errors in protocol specification drafts.
5510 * Created lib/silccore/silcnotify.c to implement Notify Payload
5511 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5512 generic payloads described by protocol specifications. The file
5513 includes implementations for ID Payload and Argument Payload.
5515 * Changed Command Payload implementation to use the new Argument
5516 Payload. Changed command_xxxx_payload to command_payload_xxxx
5517 to comply with SILC coding conventions.
5519 * Added suppport for Argument Payload handling in Notify Payload
5520 implementation as protocol requires it. Added the new support
5521 into server and client lib as well.
5523 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added support for multiple nicknames on same channel. [n] is
5526 added locally to the nickname if there are more than one same
5527 nicknames on the channel.
5529 * Server now sends all nicknames that matched WHOIS request.
5530 Client also shows the list received from server.
5532 * Added TOPIC command to client side. User can now set and show
5533 current topic on channel.
5535 * Added MOTD command to client and server. Also, server sends the
5536 motd when client connects to the server.
5538 * Changed version strings to comply ISO 8601.
5540 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Fixed protocol error handling in client library. It should now
5543 cope even if the SKE fails for some reason.
5545 * Made new protocol specification drafts for submitting to IETF.
5547 * Implemented TOPIC command to server in silcd/command.c.
5549 * Added two new notify types into lib/silccore/silcnotify.h:
5550 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5551 notify nickname change and topic setting/change on a channel.
5553 * API change of command_reply operation in client library. The
5554 application gets now the status type received from server as well.
5556 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5560 * Cras fixed and optimized the packet handling even further and
5561 it should work now. Minor change to the prototype of function
5562 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5564 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added new function into lib/silcutil/silcschedule.[ch]:
5567 silc_schedule_with_fd to select() a specified fd. The function
5568 returns after timeout expires or data arrives or goes. The
5569 function is used by packet routines to wait that all data is
5570 received from network.
5572 * Fixed data reading from network in lib/silccore/silcpacket.c.
5573 The code now assures that all data is read from the fd and then
5574 continues packet processing. This was a bug fix since the code
5575 used to drop some data in some circumstances.
5577 * Added new function into lib/silcclient/client.[ch]:
5578 silc_client_start_key_exchange to start key exchange after
5579 connection has been established to server. The code internally
5580 now uses this funtion but its main purpose was to provide it
5581 for applications that perform their own connecting. After
5582 application has created a connection it merely calls this
5583 function to start the key exchange between client and server.
5584 The library takes care of everything else after that.
5586 Updated also lib/silcclient/README to explain the usage of
5589 * Do not send to application information that connection has
5590 been established. Application gets notified it by connect
5593 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Applied cras's patch to add silc_schedule_one function. The
5596 function runs scheduler once and returns.
5598 * Fixed the scheduler after cras messed it up. The timeout
5599 handling works now as it's supposed to work.
5601 * Added into lib/silccore/ silcnotify.h to include notify
5602 message types support. Changed silc_server_send_notify*
5603 functions, in server.[ch], to support those new notify types.
5604 Added the support for the notify types into client library,
5605 as well. Added new notify client operation into ops.h in
5608 * Changed silc_server_packet_send_to_channel to send normal
5609 packets instead of just channel message packets. The function
5610 is now used to send the notify packets to channels. It is not
5611 used to send channel message packets anymore, as server never
5614 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5615 va_arg()s as it seems to require it nowadays. I guess, if SILC
5616 is compiled with older va_arg() the new code should work anyway.
5618 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Splitted core library. Core library (lib/silccore) includes
5621 now only SILC protocol specific core (and common) components.
5622 Created new utility library (lib/silcutil) that includes more
5623 generic purpose stuff. The stuff for util library was taken
5624 from the old core library. This was minor and easy split.
5626 * Created SILC Client Library (lib/silcclient) that includes
5627 implementation of the SILC client without user interface. This
5628 was major move from silc/ directory. The code has been changed
5629 so that it is transparent towards the user interface. The
5630 silc/ directory includes now the same user interface as before
5631 and it uses the new client library. Read lib/silcclient/README.
5632 Basicly, the client library performs everything else related
5633 to SILC except user interface handling. Also, configuration
5634 files are considered to be part of user interface and library
5635 does not handle them.
5637 This change also changed a lot of structures, function naming etc.
5638 Most important change was that SilcClientWindow object was
5639 renamed to SilcClientConnection in the client library. Created
5640 also new file lib/silcclient/ops.h. Also added new files
5641 silc/local_command.[ch] and silc/client_ops.[ch].
5643 All these changes were made to make it easier for user interface
5644 designers to create what ever user interface for the SILC client
5647 It is also expected that the server will be moved to lib
5648 directory as well and SILC Server Library will be created;
5649 sometimes in the future.
5651 * Removed Local commands from lib/silccore/silccommand.h as
5652 they are application specific and new client library does not
5653 handle any of those anymore.
5655 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5656 old client implementation in silc/.
5658 * Added support for callback functions in SILC_LOG_* macros.
5659 Application can now set its own callbacks that will be called
5660 instead of using the default functions that will always print
5661 the debug messages to stderr (or stdout). Also, debugging can
5662 now be disabled by setting silc_debug to FALSE and re-enabled by
5663 setting it to TRUE. Note, that logging will still work even
5664 if debugging is disabled.
5666 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5667 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5668 silc_log_reset_debug_callbacks.
5670 * To enable debugging in silc client one must give now -d
5671 option on command line.
5673 * Changed silc_schedule_init to automatically allocate task queues
5674 if they are not allocated before calling it.
5676 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Added GMP 3.1 into math library.
5680 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5683 a channel in SILC network. The packet is used by servers and
5684 routers to notify other routers that user has left a channel.
5685 This little feature was missing until now. Added the feature
5686 to protocol specification as well.
5688 Added functions: silc_server_send_remove_channel_user and
5689 silc_server_remove_channel_user into server.[ch].
5691 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5692 lib/silccore/silcpacket.h. However, they are not implemented
5695 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Fixed joining to a channel and sending channel messages
5698 between server and router. The channel message sending should
5699 now work inside a cell.
5701 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Fixed the private message sending between server and router.
5704 The private message sending should now work inside a cell.
5706 * Added silc_server_replace_id into server.[ch] to replace
5707 existing ID in the SILC network.
5709 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5710 and silc_idlist_replace_server_id into idlist.[ch] in server.
5712 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Fixed the server to server connections. Server can again now
5715 connect to router. Router to router connections probably does
5718 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Added dynamic protocol registering support. Now protocols can
5721 registered and unregistered on the fly. Patch by cras.
5723 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Added lib/contrib directory to hold routines that some platforms
5726 don't have but are needed by SILC.
5728 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5729 into lin/contrib to provide getopt() and getopt_long() for
5730 those who don't have it.
5732 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Added AWAY command to client. When away message is set and
5735 client receives a private message packet the client automatically
5736 replies to the sender with the away message.
5738 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5739 bug seemed to be the cause of recent problems when compiling
5742 * Added version detection support to SKE protocol specification
5743 and added the new changes to the SKE implementation as well.
5744 There were other minor changes in the SKE protocol as well.
5746 Many changes in lib/silcske/silcske.[ch] and in
5747 lib/silcske/payload.[ch].
5749 * Added ^U functionality, clear input line. Patch from cras.
5751 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Mainly small bugfixes on core library. Fixed some debugging
5754 logging and buffer overflow in silclog.c.
5756 * Updated config.sub and config.guess on the distribution tree.
5758 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Added command lagging support in server. Client may execute
5761 commands now only once in two seconds.
5763 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Optimized packet reception. MAC computation and checking is now
5766 also more optimized. A lot previously duplicated code is now
5767 used as generic by both client and server.
5769 * Fixed key pair generation in clientutil.c
5771 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Added into lib/silccore/silcbufutil.[ch] new function;
5774 silc_buffer_realloc.
5776 * Moved generic packet sending/encryption functions to
5777 lib/silccore/silcpacket.[ch] from client and server. Some
5778 rewriting of the functions.
5780 * Moved all generic packet reception/decryption functions to
5781 lib/silccore/silcpacket.[ch] from client and server. The
5782 packet processing is now much cleaner in both client and server.
5783 These were major changes in both client and server.
5785 * Created many common functions in server to do packet sending.
5786 Previously code were duplicated a lot, this has been removed
5789 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Rewrote major parts of the ID cache system. Don't know
5792 whether it is better now or not but at least the API is more
5795 * Major rewrite on ID cache stuff on client because of the ID
5796 cache API changes. Added idlist.c to client.
5798 * Also major rewrite on ID cache stuff on server as well.
5799 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5800 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5801 in hand, instead they are all put into the ID cache system now.
5802 All server_idlist_* routines uses ID cache now instead of
5803 traversing its own lists (those lists does not exist anymore).
5804 SilcIDList though still exists. Also, SilcXXXEntry's are
5807 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Finally made the SKE implementation compliant to the protocol
5810 specification. All mp integers are now binary encoded as
5811 opposed being HEX encoded.
5813 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5816 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5817 functions: silc_[encode/decode]_pem. Also added function
5818 silc_encode_pem_file to PEM encode with newlines ('\n') for
5821 * SILC public keys are now encoded either PEM or binary. Same
5822 option is for private keys as well. By default private keys
5823 are binary encoded and public keys PEM encoded. Silly HEX
5824 encoding were removed.
5826 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5827 function to create fingerprints.
5829 * Fixed a bug in SHA1; does not change the original data anymore.
5831 * Partly implemented INFO command on client and server side.
5832 Fixed CLEAR command. Changes to SERVER command; show current
5833 server(s) when giving command without arguments. Added
5834 VERSION command to client.
5836 * Added check to server that unregistered connections cannot
5837 execute commands (unless it is specificly allowed).
5839 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Fixed screen refresh.
5843 * Fixed channel joining bug from client. On some circumstances
5844 client tried to join to a channel it had already joined.
5846 * Added public key verification process into client's protocol.c.
5847 The client now verifies the public key from user and saves
5848 it into ~./silc/serverkeys/ directory.
5850 Added into: clientutil.[ch]: silc_client_verify_server_key.
5852 * Changed SKE protocol's silc_ske_initiator_finish function
5853 to accept callback function that verifies the received public
5854 key. Removed old silc_ske_verify_public_key function.
5856 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5859 silc_pkcs_private_key[_data]_set.
5861 * Made the password and public authentication more cleaner in
5862 server's protocol.c.
5864 * Removed historic and obsolete protocol `channel_auth' from
5865 both client and server.
5867 * Removed wrong way of sending command status messages from
5868 server to client in server's command.c. The old way violated
5869 protocol specification.
5871 Changes to silccore/silccommand.[ch]: removed
5872 silc_command_encode_status_payload -> not needed anymore,
5873 changed silc_command_encode_payload_va to accept extra
5874 argument on variable argument list. The argument type must
5875 now be provided to the function. Also, added new function:
5876 silc_command_encode_reply_payload_va which is same as
5877 normal command_encode_payload_va except command status type
5878 is provided as extra argument.
5880 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Added ~./silc directory handling. The directory includes the
5883 public and private keys for the client.
5885 Added silc_client_check_silc_dir, silc_client_create_identifier
5886 and silc_client_load_keys.
5888 * Implemented SILC protocol compliant public key. Added public
5889 and private key saving to and loading from files.
5891 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5892 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5893 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5894 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5895 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5897 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5898 silc_pkcs_load_[public/private]_key.
5900 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added silc_server_get_route (route.[ch]) to get connection
5903 data for the fastest route for given ID.
5905 * Implemented INVITE command on client and server. The command
5906 were re-defined in the SILC Protocol Specification and the
5907 implementation now complies with the specification.
5909 * Implemented PING command on client and server.
5911 * Implemented NAMES command on client and server. The server side
5912 supports currently only normal server not router server yet.
5913 Some changes to NAMES definition in SILC protocol specification.
5915 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Implemented LEAVE command on client and server.
5919 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5920 again. This change was made to the protocol as well. Server
5921 should not violate the protocol specification anymore.
5923 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5926 was tested. SOCKS4 was not but should work anyway.
