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

82 of the client's public key (if the proof of posession of the
83 corresponding private key is verified by the server).
84 Updated to the protocol specification.
86 * Added support of receiving the client's public key's
87 fingerprint in command reply in client library. Affected
88 file is lib/silcclient/command_reply.c, and

147 during SERVER_SIGNOFF, but invalidate it. This way we
148 preserve the WHOWAS info for the client. Affected file
151 * Fixed SERVER_SIGNOFF notify handling in the server. The
152 server is now able to process incoming SERVER_SIGNOFF notify
153 for a server that it doesn't even know about. It will remove
154 the clients provided in the notify. Affected file
155 silcd/packet_receive.c.
157 * Check for partial packet in data queue after every packet that
158 was found from the queue. Return and wait for more data if

184 available. It is used in padding generation. Affected file
185 lib/silccrypt/silcrng.[ch].
187 * All packets in client library are now processed synchronously.
188 Optimized packet processing a lot. Affected file
189 lib/silcclient/client.c.
191 * All server connection packets are processing synchronously
192 now in server, to optimize packet processing. Affected file
195 * Include files are installed now only in Toolkit distribution
196 if make install is given. Affected files: all Makefile.am's.
198 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
200 * Assure that silc_client_notify_by_server_resolve does not
201 resolve the client information multiple times. If it cannot
202 be found by the first it cannot be found at all. Affected
203 file lib/silcclient/client_notify.c.
205 * Fixed WHOWAS command reply calling. Affected file
206 lib/silcclient/command_reply.c.
208 * Removed all references to silc_idlist_get_client from the
209 Irssi SILC client since that call is internal call used by
210 the library. The Irssi SILC client will use now client
211 retrieval functions found in silcapi.h.
213 * Fixed a bug in resolving nickname info before sending
214 private message. It used freed memory. Affected file
215 irssi/src/silc/core/silc-servers.c.
217 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

241 in packet queue that we are not able to process without first
242 processing packets before them. Affected file silcd/server,
243 lib/silcclient/client.c.
245 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
246 whether library should continue processing the packet.

338 The SILC packet header change makes it impossible to be
339 backwards compatible.
341 * Send the ENDING packet with timeout in the backup resuming
342 protocol. This is to assure that all routers has connected
343 to the primary router. Affected file silcd/server_backup.c.
345 * Changed the RNG to take the first IV from random data. It
346 used to take it from zero actually. Changed the RNG also

353 (the packet length) encrypted. Affected files aroung the
354 code tree, lib/silccore/silcpacket.[ch]. Removed the
355 SilcPacketCheckDecrypt callback. It is not needed anymore
356 since the silc_packet_receive_process will determine now
357 whether the packet is normal or special.
359 * Implemented the unidirectional MAC keys. Affected files
360 lib/silcske/silcske.c, silcd/protocol.c and
361 lib/silcclient/protocol.c.

370 * Allow backup router to announce servers. All servers
371 announced by backup router are added to the global list
372 automatically. Update hte server's socket to our primary
373 router also when backup router announces a server.
374 Affected file silcd/packet_receive.c.
376 * Do not update the client->router in the function
377 silc_server_udpate_clients_by_server if the client is on
378 global list. We might fail to find any specific server
379 for locally connected clients and local cell clients. They
380 should still use the `from' and not `to' as client->router.
381 This fixes backup router resuming protocol. Affected file
384 * Decrease channel statistics count only if the channel
385 deletion worked. Affected files are silcd/server.c and

424 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
425 Affected file silcd/packet_send.c.
427 * Changed the SFTP Filesystem interface. Changed the
428 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
429 the filesystem operation function. The SilcSFTPFilesystem
430 is now a context that is allocated by all filesystem allocation
431 functions and it already includes the operations structure
432 and filesystem specific context. It is given as argument
433 now to the silc_sftp_server_start. This made the interface
434 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
435 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
437 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
439 * Changed the backup router adding and getting interfaces
440 in the server. The router that will be replaced by the
441 specified backup router is now sent as argument. Affected

560 of the internet draft is lib/silccore/silcpacket.h.
562 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
563 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
564 is used as part of backup router protocol when the primary
565 router of the cell is back online and wishes to resume
566 the position as primary router.
568 * Redefined the MAC generation keys in the protocol. The
569 same key is not used anymore in both direction. Both
570 direction will now use different keys for sending and
571 receiving. This fixes a potential security flaw. This
572 change causes incompatibilities in the protocol.
574 * Redefined also the MAC computation from the packet.
575 An packet sequence number is now added to the MAC
576 computation. This prevents possible replay attacks against
577 the protocol. This change too causes incompatibilities
580 Added `sequence' field to the SilcPacketContext to hold
581 the current sequence number for the packet.
583 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
585 * Added `created' field to the SilcIDListData in the file
586 silcd/idlist.h to indicate the time when the entry was
589 * Added `created' field to the SilcChannelEntry too. Affected
592 * Added `creation_time' aguments to all the announcement functions
593 in the server. If it is provided then only the entries that
594 was created after the provided time frame are actually
595 announced. Affected file silcd/server.[ch].
597 * The protocol says that the Channel ID's IP address must be
598 based on the router's IP address. Added check for this in
599 the silc_server_new_channel when processing incoming New Channel
600 Payload. Affected file silcd/packet_receive.c.
602 * Print out the correct version with --version in SILC client.
603 Affected file irssi/src/silc/core/silc-core.c.
605 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
607 * Fixed WHOWAS command to check for completnes of the client
608 entry always, not just when the command is coming from client.
609 Affected file silcd/command.c.
611 * Added new function silc_server_packet_queue_purge to purge the
612 outgoing data queue to the network. After the function returns
613 it is guaranteed that the outgoing packet queue is empty.
614 Affected file silcd/packet_send.[ch].
616 * Purge the outgoing packet queue in the rekey protocol's final
617 callback to assure that all rekey packets go to the network
618 before quitting the protocol. Affected file silcd/server.c.
620 * Added silc_client_packet_queue_parse as similar function as
621 in server to the client library. The affected file is
622 lib/silcclient/client.c.
624 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
626 * Splitted silcd/server.c and created silcd/server_util.[ch]
627 for utility functions.
629 * Added new socket flag SILC_SF_DISABLED to indicate that the
630 connection is open but nothing can be sent to or received from
631 the connection. Affected file lib/silcutil/silsockconn.[ch].
632 The checking for disabled socket is checked in the low level
633 silc_socket_write and silc_socket_read functions.
635 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Allow only nicknames and channel names that fits into the
638 7-bit unsigned char ASCII set. Affected file silcd/command.c.
640 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
642 * When processing JOIN command reply in server check that if
643 the channel exists in our global list we'll move it the local
644 list. Affected file silcd/command_reply.c.
646 * Fixed the check whether client is joined on the channel already
647 in JOIN command. Affected file lib/silcclient/command.c.
649 * Fixed the JOIN command reply to check whether the channel
650 already exists. Affected file lib/silcclient/command_reply.c.
652 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
654 * Added silc_ske_status_string to map the SKE error numbers
655 to readable strings. The affected files are
656 lib/silcske/silcske[_status].[ch].
658 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Do not show the private channels on the WHOIS channel list
661 as it is not allowed by the protocol. The affected file is
664 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
666 * Assure that the packet length digged from the actual packet
667 is something sensible in the silc_packet_decrypt_rest_special
668 in lib/silccrypt/silcpacket.c.
670 * Free and NULL the allocated pointer in silc_hmac_alloc if
671 the HMAC allocation fails. The affected file is
672 lib/silccrypt/silchmac.c.
674 * Print the selected security properties to the log files in
675 the server. Affected file silcd/protocol.c.
677 * Add SKE's reference counter even if calling the completion
678 callback manually. Otherwise it goes negative, although it
679 does not cause any problems. The affected file is
680 lib/silcske/silcske.c.
682 * Remove the client entry with short timeout after giving the
683 KILL command. Affected file lib/silcclient/command.c.
685 * Fixed to send error reply in WHOIS and IDENTIFY commands in
686 case all found clients are already disconnected (WHOWAS would
687 found them) in the server. Affected file silcd/command.c.
689 * Update the last_receive (time of last data received) to be
690 updated only when received private or channel message so that
691 the idle time showed in WHOIS makes more sense.
693 * Added boolean field `valid' in to the SilcClientEntry in the
694 client library to indicate whether the entry is valid or not.
695 This fixes the nickname change bug on channel when changing
696 the nickname to be same than the old (like nick to Nick) the
697 nickname formatter doesn't set the new nick anymore to Nick@host.
698 Affected file lib/silcclient/idlist.[ch].
700 * Now actually fixed the nickname changing on disconnection.
701 Added new function silc_change_nick to the Irssi SILC Client.
702 Affected file irssi/src/silc/core/client_ops.c,
703 irssi/src/silc/core/silc-nicklist.[ch].
705 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
707 * Check that the public key exists in the GETKEY command before
708 trying to encode it. Affected file silcd/command.c.
710 * Print some notifications on received public keys with GETKEY
711 command in the Irssi SILC Client. Affected files are
712 irssi/src/fe-common/silc/module-formats.[ch],
713 irssi/src/silc/core/client_ops.c.
715 * Use IDENTIFY command to resolve the server information in the
716 GETKEY command instead of INFO command. Affected file
717 lib/silcclient/command.c.
719 * All command reply functions in the client library now calls
720 the pending command reply callbacks even if an error has
721 occurred. The server has done this a long time and now it was
722 time to move the client library to this as well. Now all
723 errors can be delivered back to the pending command reply
724 callbacks if necessary. Affected files are
725 lib/silcclient/command[_reply].[ch].
727 * Change the nickname on disconnection back to the username
728 because in reconnect the server will enforce it to it anyway.
729 Affected file irssi/src/silc/core/silc-servers.c.
731 * Fixed a config file parsing bug in the Irssi SILC client.
732 Affected file irssi/src/silc/core/clientconfig.c.
734 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
736 * When printing the channel mode on JOIN, verify that the
737 channel key and channel's HMAC are valid. Affected file
738 irssi/src/silc/core/client_ops.c.
740 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
742 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
743 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
744 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
746 * Removed channel key rekey task deleting from the function
747 silc_server_save_channel_key. Affected file silcd/server.c.
748 Added explicit timeout task context instead that is used to
749 delete the task if we are registering a new task before the
750 new task has elapsed.
752 * When channel key rekey occurs the client library now saves
753 the old channel key for a short period of time (10 seconds) and
754 is able to use it in case some is still sending channel
755 messages encrypted with the old key after the rekey. Affected
756 file lib/silcclient/[idlist.h|client_channel.c].
758 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
760 * Added check to the silc_server_new_id_real to not accept
761 new ID if it is the sender's own ID. Affected file is
762 silcd/packet_receive.c.
764 * Assure that we do not announce ourself or the one we've
765 sending our announcements when we're router and are announcing
766 servers to our primary router. Affected file silcd/server.c.
768 * Fixed silc_server_command_identify_check_client to assemble
769 correct WHOIS packet. It send corrupted WHOIS packet and
770 caused problem with router to router connections. Affected
771 file silcd/command.c.
773 Fixed also silc_server_command_whois_check the same way
774 as for the IDENTIFY command.
776 * Added new SilcIDListStatus to the server in the SilcIDListData
777 structure. The status now includes the current status of
778 the entry (like registered, resolved etc.). Affected file
779 silcd/idlist.[ch]. Defined a bunch of different status types
780 as well. This replaced the old boolean registered field as well.
782 Added resolve_cmd_ident field to the SilcClientEntry structure
783 too so that if the entry is for example being resolved so
784 another command may attach to the same pending command reply
785 without requiring to resolve the same entry again. This concept
786 should optimize the WHOIS and the IDENTIFY resolving under
787 heavy load by taking away unnecessary resolving for entries
788 that are being resolved already.
790 Added support for adding multiple pending commands for one
791 command idenfier. Affected file silcd/command[_reply].[ch].
793 * Fixed WHOIS and IDENTIFY save to remove the cache entry
794 before deleting the data. Otherwise the hash table will have
795 freed data in comparison functions. Affected file is
796 silcd/command_reply.c.
798 * Fixed silc_idlist_replace_client_id to add the new entry to
799 the cache with NULL nickname. Otherwise there will be invalid
800 memory as the nickname after the nickname is freed. Affected
801 file silcd/packet_receive.c.
803 * Fixed the silc_idlist_get_clients_by_hash. The entries was
804 saved into wrong slots because the previous number of entries
805 was not taken into account. Affected file silcd/idlist.c.
806 Fixed same thing in silc_idlist_get_clients_by_nickname too.
808 * If we are router and we receive JOIN notify to a channel that
809 does not have any users then notified client is marked as the
810 channel founder, as it is it. The affected file is
811 silcd/packet_receive.c
813 * Added to the extended hash table API's table_del_*ext functions
814 the destructor as argument too, so that the caller can decide
815 which destructor to use or whether to use destructor at all.
816 Affected file lib/silcutil/silchashtable.[ch].
818 * Fixed ID Cache purging. It actually deleted the entries from
819 the hash table after the data was freed. The hash table ended
820 up comparing freed memory. The affected file is
821 lib/silccore/silcidcache.c.
823 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
825 * Fixed Irssi SILC client's KILL command's HELP syntax.
827 * The USERS command now resolves the detailed user information
828 if the userinfo field is missing. Affected file is
829 lib/silcclient/command_reply.c.
831 * Do not print error in silc_file_read if the read file does
832 not exist. Just silently return NULL. Affected file is
833 lib/silcutil/silcutil.c.
835 * Fixed the silc_log_output to not wine about NULL filename
836 and to not create some bogus " " filename. Affected file is
837 lib/silcutil/silclog.c.
839 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Fixed various printing bugs on the user interface in the
842 Irssi SILC Client. Minor changes that were forgotten from
845 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
847 * Fixed the configure.in.pre and the compilation and distribution
848 environment to support the new autoconf 2.52. That version is
849 now required to compile the CVS trunk.
851 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Renamed function silc_parse_nickname to silc_parse_userfqdn
854 to generally parse user@fqdn format strings. Affected file
855 lib/silcutil/silcutil.c.
857 * Added nickname_format and nickname_force_format fields to the
858 SilcClientParams structure. The first one defines the format
859 for the nicknames that the library will enforce if the receives
860 multiple same nicknames. The second one is boolean value and
861 can be used to force the library to always enforce the format
862 to the nicknames regardles whether there are multiple nicknames
863 or not. This configurable formatting was employed to flexibly
864 support accessing multiple nicknames from the user interface.
865 The userinterface can now set the nicknames to what ever format
866 they prefer. Affected file lib/silcclient/silcapi.h.
868 Added function silc_client_nickname_format to the file
869 lib/silcclient/idlist.c. It performs the nickname formatting.
871 Added new field `hostname´ to the SilcClientEntry context.
872 It holds the hostname of the client. Affected file is
873 lib/silcclient/idlist.h.
875 * Irssi SILC Client sets the nicknames in nick@hostn format.
876 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
877 irssi/src/silc/core/silc-core.c.
879 The WHOIS printing now also shows both the real nickname and
880 the formatted nickname so that user knows how to access the
881 user if there are multiple same nicknames cached. Affected
882 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
883 printing formatting too to take the hostname now as a separate
884 argument. The Affected file is
885 irssi/src/fe-common/silc/modules-formats.[ch].
887 * Changed the silc_client_get_clients_local to accept the formatted
888 nickname as argument. It accepts the real nickname too but the
889 formatted nickname can be used to find the true entry from
890 multiple entries. Affected file lib/silcclient/silcapi.h and
891 lib/silcclient/idlist.c.
893 * Added nickname_format_parse field to the SilcClientParams.
894 It is a callback function provided by the application to parse
895 the nickname out of the formatted nickname string. The library
896 calls it to get the nickname from the formatted string. Since
897 the application generally knows better the format of the nickname
898 string it parses it instead of the library, even though library
899 encodes the formatted string. If the callback function is not
900 provided then the library will use the string as is. The
901 affected file is lib/silcclient/silcapi.h.
903 * All the nickname strings passed to the client library in
904 commands are now expected to be formatted nickname strings.
905 If the command does not support the formatted nickname string
906 it will assume that the sent string is the actual nickname.
907 Affected file lib/silcclient/command.c.
909 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
911 * Added public key authentication support to OPER and SILCOPER
912 commands in the client library. Affected file is
913 lib/silcclient/command.c.
915 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
917 * Changed the get_auth_methdod client operation to be asynchronous.
918 It can be async if the application resolves the authentication
919 method from the server during the negotiation. Added new
920 SilcGetAuthMeth completion callback that the application will
921 call after resolving the authentication method.
923 Added function silc_client_request_authentication_method that
924 the application can use to resolve the authentication method
925 from the server. Added also SilcConnectionAuthRequest callback
926 that the library will call after the server has replied. The
927 application can call this function if it does not know the
928 current authentication method.
930 Affected files are lib/silcclient/client.c and
931 lib/silcclient/silcapi.h.
933 * The Irssi SILC client now automatically resolves the authentication
934 method incase any configuration information is not present (and
935 currently there never is). The affected file is
936 irssi/src/silc/core/client_ops.c.
938 * Fixed public key authentication from the client library.
939 Affected file lib/silcclient/protocol.c. Changed also the
940 protocol specification about the public key authentication in
941 the connection authentication protocol. The actual data to be
942 signed is now computed with a hash function before signing.
944 * Fixed the public key authentication from the server as well.
945 Affected file silcd/protocol.c.
947 * Removed the mlock()'s from the memory allocation routines.
948 Affected file lib/silcutil/silcmemory.c. The ./configure does
949 not check anymore for the mlock(). Affected file is
952 * Fixed USERS command in server to allow the execution of the
953 command for private and secret channels if the client sending
954 the command is on the channel. Affected file silcd/command.c.
956 * Fixed silc_client_get_clients_local to return the clients
957 count correctly. It could return wrong value. Affected file
958 lib/silcclient/idlist.c.
960 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
963 types. The assembler optimizations seemed not to like 64-bit
964 data types. The assmebler optimizations thus are now enabled
965 also for BSD systems as opposed to only enable them for Linux.
967 * Do not check for threads at all on BSD systems. Affected
968 file configure.in.pre.
970 * Removed -n and -h options from the Irssi SILC Client since
971 they are not used in silc.
973 * Fixed the prime generation to assure that the first digit
974 of the generated random number is not zero since our conversion
975 routines does not like number strings that starts with zero
976 digit. If zero digit is seen the random number is regenerated.
977 This caused some corrupted RSA keys when the zero first digit
978 was met. Affected file lib/silcmath/silcprimegen.c.
980 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Fixed WIN32 configuration in the ./configure script.
983 Fixed to include xti.h on environments that has it.
984 Patches by Carsten Ilchmann and andrew.
986 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
988 * Changed the silc_id_create_client_id to be collision
989 resistant. It is now assured that there cannot be created
990 two same client ID's. I suspect that some weird bugs in
991 the server were actually caused by duplicate Client IDs.
992 Affected file silcd/serverid.[ch]. A router receiving
993 new ID now also assures and informs the sending server
994 if the ID caused collision.
996 * Changed the silc_id_create_channel_id to also assure that
997 there are no collisions.
999 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Statement about ignoring the Mutual Authentication flag when
1002 performing rekey with PFS was a bit misleading. It is ignored
1003 if it was set in the initial negotiation, it cannot be even
1004 set in the rekey. Fixed in the ke-auth draft. Started the
1005 new versions of the protocol drafts in the doc/.
1007 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Fixed a bug in silc_client_command_identify_save when saving
1010 new channel information. The channel name was no duplicated
1011 and caused crash on exit. Affected file is
1012 lib/silcclient/command_reply.c.
1014 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * Fixed the getkey command handling in the server. Send just
1017 empty OK reply to the sender if the key could not be fetched
1018 (but everything else was ok, like the key just was not available).
1019 Changed the public key parameter to optional in the protocol
1020 specs so that empty OK reply can be sent. Affected file
1023 Added a message to Irssi SILC client to tell to user if the
1024 server did not return a public key.
1026 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Fixed a channel key regeneration bug. It registered new
1029 timeout tasks exponentially until all system resources were
1030 used. Affected file silcd/server.c.
1032 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Added the SILC Document generator to the scripts/silcdoc.
1035 It can be used to generate the Toolkit Reference Manual out
1036 of the source tree. Internally it will also use the RoboDoc
1037 generator now imported in util/robodoc.
1039 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Added couple of return's in rekey protocol if error orccurred
1042 during the protocol. The execution must be terminated.
1043 Affected file silcd/protocol.c. Also, terminate the protocol
1044 always with timeout.
1046 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * The client's Client ID was created initally from the wrong
1049 nickname (it could have been in format nick@host) in the
1050 silc_server_new_client. Affected file silcd/packet_receive.c
1052 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Added some SILC_LOG_ERROR's to various error conditions
1055 if client could not be added to ID cache. Affected files
1056 silcd/packet_receive.c and silcd/server.c.
1058 * When client's sock->user_data is freed, NULL also the
1059 client->router and client->connection pointers. Added check
1060 for these pointers being NULL to various places around the
1061 code. Affected file silcd/server.c.
1063 * Added client->data.registered == TRUE checks to various
1064 places around the code to assure that unregistered client's
1065 are not handled when it is not allowed. Affected file
1068 * Added `bool registered' fields to all
1069 silc_idlist_[server|client]_get_* routines to indicate whether
1070 the fetched client needs to be registered or not. Affected
1071 file silcd/idlist.[ch].
1073 * Add your own entry as registered to the ID cache in the
1074 server. Affected file server.c.
1076 * Fixed a bug in silc_server_new_server. The SilcServer was
1077 set as the new server's context instead of SilcServerEntry.
1078 This naturally caused some weird bugs.
1080 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Do not delete the channel rekey task when adding it
1083 for in silc_server_create_channel_key.
1085 * Changed the silc_server_create_channel_key to return
1086 TRUE or FALSE to indicate the success of the channel key
1089 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Fixed MSVC++ project files and added missing files to
1092 Makefiles under win32/.
1094 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Do not add TCP_NODELAY flag if the operating system
1097 does not have it defined. Affected files are
1098 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1100 * Fixed buffer overflow from Irssi SILC Client. Affected
1101 file irssi/src/fe-common/core/themes.c.
1103 * Fixed double free in client library in the file
1104 lib/silcclient/client.c when disconnecting from server.
1106 * Applied double free patch from cras to Irssi SILC client.
1107 Affected files irssi/src/core/[modules/expandos].c
1109 * Fixed the disconnection handling to Irssi SILC Client.
1110 The application must call silc_client_close_connection
1111 in ops->connect client operation in case of failure of
1112 the connection. Affected file is
1113 irssi/src/silc/core/client_ops.c.
1115 * Do not set sock->protocol to NULL in the function
1116 silc_client_close_connection after executing the protocol's
1117 final callback since the sock might not be valid anymore.
1118 Affected file lib/silcclient/client.c.
1120 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Do not enable SILC_THREADS if the linking with libpthread
1123 did not happen. Affected file configure.in.pre.
1125 * Added notion to protocol specification that server must
1126 verify the sent authentication payload with CMODE when
1127 setting the channel founder key. Implemented it to the
1128 server. Affected file silcd/command.c.
1130 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * Added _EXTRA_DIST SILC distribution variable to the
1133 distributions file. It is used to conditionally add extra
1134 files or directories to the specific distribution. Affected
1135 files ./prepare, Makefile.am.pre and distributions.

1140 * Added README.WIN32 for instructions to compile the Toolkit
1143 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1145 * Fixed a double free in disconnection in the server. Affected
1146 file is silcd/server.c.
1148 * Fixed the lib/silcske/groups.c to work now also with GMP
1149 MP library. The string conversion did not work when using
1150 specific base and the base is indicated in the string as well.
1152 * Created win32/ directory which now includes MSVC++ specific
1153 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1154 It will appear only in the toolkit distribution
1156 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Changed the key material distribution function in case when
1159 the hash output is too short. The data is now concatenated
1160 a bit differently than it used to. Made the change to the
1161 SKE protocol specification.
1163 * Added better GMP detection to configure.in.pre. A patch
1166 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Fixed a minor bug in SKE that might cause some problem on
1169 some platforms. Affected file lib/silcske/silcske.c.
1171 * Added the cookie checking for initiator in the SKE. It checks
1172 that the responder returns the sent cookie unmodified. The
1173 affected file is lib/silcske/silcske.c. Added new SKE
1174 error type INVALID_COOKIE that can be sent during the
1175 negotiation. Fixed some memory leaks as well.
1177 * Added the "invalid cookie" error message to Irssi SILC client's
1180 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * Added `task_max' field to the SilcClientParams to indicate
1183 the maximum tasks the scheduler can handle. If set to zero,
1184 default values are used. Affected file lib/silcclient/silcapi.h.
1186 * Fixed memory leaks in silc_client_close_connection. Affected
1187 file lib/silcclient/client.c.
1189 * Added silc_client_del_client_entry to client library to free
1190 all memory of given client entry. Affected file is
1191 lib/silcclient/idlist.[ch].
1193 * Added new functions silc_client_del_channel and
1194 silc_client_del_server to delete channel and server entries.
1195 Affected file lib/silcclient/[silcapi.h/idlist.c].
1197 * Removed silc_client_del_client_by_id from silcapi.h.
1199 * Fixed the INFO command to return the server's own info
1200 correctly when querying by Server ID. Affected file is
1203 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Removed the non-blocking settings in WIN32 code in the
1206 silc_sock_[read/write] and added SleepEx instead. Affected
1207 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1208 of input data is now checked with FIONREAD and ioctlsocket.
1210 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Call silc_schedule_task_del_by_context in the
1213 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1214 Affected file lib/silccore/silcprotocol.c.
1216 * Call silc_protocol_cancel for active protocols in the
1217 silc_server_close_connection if the funtion
1218 silc_server_free_sock_user_data has not been called.
1219 Affected file silcd/server.c.
1221 * Generic tasks cannot be deleted using the del_by_fd
1222 task deleting function since generic tasks does not match
1223 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1225 * Added a notion to SILCOPER help file that the SILCOPER works
1226 only on router server, not on normal server.
1228 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Added for WIN32 support for the new scheduler as well.
1231 Affected file lib/silcutil/win32/silcwin32schedule.c.
1233 * Fixed the SHA1 implementation to work on various platforms.
1235 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1238 API. It is part of the scheduler now. Everything else is
1239 as previously but some functions has changed their names.
1240 Checkout the lib/silcutil/silcschedule.h for the interface.
1241 Updated all applications to use the new interface. Affected
1242 files are lib/silcutil/silcschedule.[ch].
1244 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * Found a bug in the SKE implementation. The HASH value,
1247 specified by the protocol, was not computed correctly. The
1248 public key of the responder was not added to the computation
1249 even though it is mandatory. Affected file lib/silcske/silcske.c.
1250 This unfortunately causes incompatibilities with older
1251 clients and servers.
1253 * Added WIN32 specific network init and uninit functions:
1254 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1255 the Winsock2. Affected file lib/silcutil/silcnet.h and
1256 lib/silcutil/win32/silcwin32net.c.
1258 * Set the socket always to nonblocking mode on WIN32 after
1259 reading data or writing data. Affected file is
1260 lib/silcutil/win32/silcwin32sockconn.c.
1262 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1264 * Fixed various compilation problems under WIN32. Affected
1265 files lib/silcutil/win32/silcwin32thread.c and
1266 lib/silcutil/win32/silcwin32schedule.c.
1268 * Removed all _internal.h #includes from public header
1269 files. Internal headers must never be included from
1272 Removed also the lib/silcske/payload_internal.h file.
1274 * All include files that may be needed (public and some others
1275 included by the public headers) by application developers are
1276 now copied to the ./includes directory. It does not copy any
1277 internal headers. Affected file Makefile.defines.pre and all
1278 Makefile.am's under lib/ and subdirs.
1280 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Do not change the ~/.silc directory's permissions automatically.
1283 Affected file irssi/src/silc/core/clientutil.c.
1285 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * Do not cancel the protocol in silc_server_close_connection
1288 it might cause recursion. Now cancelled in the function
1289 silc_server_free_sock_user_data. Affected file silcd/server.c.
1291 * Fixed the silc_server_remove_clients_by_server to regenerate
1292 the channel keys correctly finally. Added also new function
1293 silc_server_remove_clients_channels to actually do it.
1294 Affected file silcd/server.c.
1296 * Fixed the silc_server_new_channel to not crash by giving
1297 wrong router to the new channel. Affected file is
1298 silcd/packet_receive.c.
1300 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1303 which is given as argument to the silc_client_alloc now.
1304 It can be used to configure the client and set various parameters
1305 that affect the function of the client.
1307 * The USERS command in server did not check whether the channel
1308 is private or secret. Affected file silcd/command.c.
1310 * Added new argument to the USERS command in protocol specification.
1311 The USERS command now can take the channel name as argument
1312 as well. Added support for this in client and server and
1313 updated the protocol specs.
1315 * Completed the GETKEY command in client. It can be now used
1316 to fetch also servers public key not only some clients.
1317 Affected files lib/silcclient/command[_reply].c.
1319 * Added silc_client_get_server to return server entry by the
1320 server name. Affected files lib/silcclient/silcapi.h and
1323 * Redefined the IDENTIFY command in protocol specification to be
1324 more generic. It now can be used to query information about
1325 any entity in the SILC Network, including clients, servers and
1326 channels. The query may be based either the entity's name
1327 or the ID. Added support for this in both client and server.
1329 Affected files silcd/command.c and lib/silcclient/command.c
1330 and command_reply.c.
1332 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1333 the _from_client and _from_server functions. Affected file
1336 * Added silc_client_get_channel_by_id_resolve to the file
1337 lib/silcclient/silcapi.h to resolve channel information by
1338 its ID. Added also silc_client_get_channel_by_id that
1339 does not resolve it from the server.
1341 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * Added SilcServerEntry context into the client library
1344 to represent one server. The INFO command now allocates
1345 these to save the resolved server info. For now on the
1346 client library will also keep information about servers,
1347 connected and resolved with INFO.
1349 The INFO command now allocates the SilcServerEntry context
1350 and saves the server info there. The COMMAND_REPLY in
1351 the INFO now returns the parameters to application in
1352 same order as defined in the protocol specification.
1354 The entries are cached in the client->server_cache.
1356 * The INFO command is now issued after received the Client ID
1357 from the server. Affected file lib/silcclient/client.c.
1359 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1360 to the application as the mode changer might be server.
1361 It is guaranteed that NULL is not returned anymore to the
1362 application. Affected file lib/silcclient/client_notify.c.
1364 The ID Type is now also passed to the application so that
1365 it can check whether the returned entry is SilcClientEntry
1368 Added new function silc_client_get_server_by_id to return
1369 the server entry by ID. Affected files are the
1370 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1372 * Do not create the channel in the Irssi SILC Client when issuing
1373 the JOIN command but when received the sucessful JOIN command
1374 reply. Otherwise the channel might get created even though we
1375 could not join it. The Affected file is
1376 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1378 * Fixed a channel joining bug in router. The router must also
1379 check the channel modes, invite and ban lists etc. when serving
1380 the JOIN command sent by normal server. Affected file is
1381 silcd/command.c. The router now resolves the client's
1382 information from the server who sent the JOIN command if it
1383 does not know it, and processes the JOIN command only after
1386 * Changed the SilcCommandCb to take new argument; void *context2.
1387 Affected file lib/silccore/silccommand.h
1389 The second argument in the command callbacks in the server now
1390 includes the SilcServerCommandReplyContext if the command was
1391 called as pending command callback from the command reply.
1392 Otherwise it is NULL. When called as pending the status of the
1393 command reply will be checked and if it was erronous the
1394 error will be sent to the original sender of the command.
1395 This way the client always receives the error messages even
1396 though the server was actually the one who received the error
1397 when it resent the command to router, for example. Affected
1398 files silcd/command[_reply].[ch].
1400 * Fixed sending WHOWAS command's error message to client if
1401 the requested client could not be found. It was missing.
1404 * Changed the CMODE and CUMODE commands reply arguments in the
1405 protocol specification. The Channel ID is now sent in both
1406 of the commands to identify the channel. Implemented this
1407 new feature to the client and server. Affected files
1408 lib/silcclient/command_reply.c and silcd/command.c.
1410 * Made better checks for invite and ban lists in the JOIN
1411 command in server. Affected file silcd/command.c.
1413 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * The server now performs the incoming host IP/DNS lookup
1416 using the silc_socket_host_lookup and thus does not block
1417 the server anymore. Affected file silcd/server.c.
1419 * Completed the multi-thread support for SILC Scheduler in
1420 the lib/silcutil/silcschedule.c.
1422 * Fixed the configure.in.pre to detect the pthread correctly
1425 * Fixed a deadlock in silc_task_queue_wakeup in the file
1426 lib/silcutil/silctask.c.
1428 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Added new function silc_schedule_wakeup that is used in
1431 multi-threaded environment to wakeup the main thread's
1432 schduler. It needs to be used when a thread adds a new task
1433 or removes a task from task queues. After waking up, the
1434 scheduler will detect the task queue changes. If threads
1435 support is not compiled in this function has no effect.
1436 Implemented the wakeup mechanism to both Unix and WIN32
1437 systems. Affected files are lib/silcutil/silcschedule.[ch],
1438 lib/silcutil/unix/silcunixschedule.c and the
1439 lib/silcutil/win32/silcwin32schedule.c.
1441 * Added new function silc_task_queue_wakeup to wakeup the
1442 scheduler by the specified task queue. Affected file
1443 lib/silcutil/silctask.[ch].
1445 * The silc_socket_host_lookup_start now wakes up the scheduler
1446 after adding the timeout task. Affected file is
1447 lib/silcutil/silcsockconn.c.
1449 * The silc_socket_host_lookup is synchronous now if the threads
1450 support is not compiled in. However, the callback is still
1451 called asyncronously through the scheduler, anyway. Affected
1452 file lib/silcutil/silcsockconn.c.
1454 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Added new function silc_socket_host_lookup to perform
1457 asynchronous IP and FQDN lookups for the socket connection.
1458 Affected files lib/silcutil/silcsockconn.[ch].
1460 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1463 that may or may not compile the mutex support in.
1465 Changed the silc_mutex_alloc interface. It allocates the
1466 mutex now to the sent pointer and returns TRUE or FALSE.
1468 Affected file lib/silcutil/silcmutex.h.
1470 * Wrote the SILC Task Queue interface to support multi-threads.
1471 Affected file lib/silcutil/silctask.[ch].
1473 * Wrote the SILC Scheduler to support multi-threads. Affected
1474 file lib/silcutil/silcschedule.c.
1476 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1479 in lib/silcutil/win32/.
1481 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1483 * Defined SILC Mutex API and SILC Thread API and implemented
1484 them for Unix. Affected files are
1485 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1486 lib/silcutil/unix/silcunixmutex.c and
1487 lib/silcutil/unix/silcunixthread.c.
1489 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Fixed the silc_server_remove_clients_by_server's channel
1492 key re-generation. The hash table handling was incorrect
1493 and would not work with many channels. Affected file is
1496 * Fixed some memory leaks around the server code.
1498 * Rewrote the silc_server_get_users_on_channel to support IPv6
1499 based Client ID's. Affected file silcd/server.c.
1501 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1502 specification. However, a separate document must be written
1503 to define the detailed signing procedure and the payload
1504 associated with the flag. Defined the flag to the
1505 lib/silccore/silcchannel.h as well.
1507 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Changed the dynamic tables to static size tables in the
1510 lib/silccrypt/silchmac.c.
1512 * Removed GCC dependencies from the code. A patch by cras.
1514 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * Do not show the error "Error receiving packet bla bla"
1517 in server if it really was not an error (-2 means that reading
1518 is pending). Affected file silcd/server.c.
1520 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1522 * Fixed a possible crash in silc_server_remove_clients_by_server
1523 in silcd/server.c. Fixed there also some memory leaks.
1525 * Fixed the silc_idlist_replace_client_id. It could replace
1526 wrong key in the hash table. Affected file silcd/idlist.c.
1528 * Do not check whether there are global users on the channel
1529 if the channel->global_users is FALSE. Affected functions
1530 silc_server_remove_from_one_channel and
1531 silc_server_remove_from_channels in silcd/server.c. Also,
1532 do not check if the removed client is local as we can be
1533 sure that global client was not removed from the channel
1534 and checking for global users is not needed.
1536 * The silc_server_remove_clients_by_server now re-generates
1537 the channel keys correctly for those channels that had
1538 clients removed from them. Affected file silcd/server.c.
1540 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1542 * Found the reason of random crashes in the server. We weren't
1543 ignoring the SIGPIPE signal (which can be sent in write())
1544 and it crashed the server. Affected file silcd/silcd.c.
1546 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Assure that sock->user_data is not NULL in the function
1549 silc_server_packet_send in silcd/packet_send.c.
1551 * Disconnect the remote connection if it could not be added
1552 to any ID lists in the server. The affected file is
1555 * Check in silc_server_packet_send[_real/dest] that the
1556 socket is not disconnecting and ignore the data if it is.
1557 Affected file silcd/packet_send.c.
1559 * Define inline to __inline on native WIN32 compilation.
1560 Affected file includes/silcwin32.h.
1562 * Added some explicit type casts for inline code since MSVC
1563 require them. Affected files lib/silcutil/silcbuffer.h,
1564 lib/trq/silcdlist.h and lib/trq/silclist.h.
1566 * Print warning in log files from now on if the packet
1567 decryption fails. Affected file silcd/server.c.
1569 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * Changed the `say' client operation's interface to accept
1572 new `type' argument to indicate the type of the message sent
1573 by the library. The application may filter the library's
1574 messages according the type. The affected file is the
1575 lib/silcclient/silcapi.h.
1577 * Added two new functions to lib/silcclient/silcapi.h:
1578 silc_client_del_client and silc_client_del_client_by_id.
1579 Affected file lib/silcclient/idlist.c.
1581 * Moved the clientincludes.h from includes/ to silc/ and
1582 serverincludes.h from includes/ to silcd/.
1584 * The modes for the CMODE and CUMODE are now passed as
1585 uint32 for application with COMMAND_REPLY. The affected
1586 file is lib/silcclient/command_reply.c.
1588 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1590 * /WHOIS without arguments shows client's own information.
1591 Affected file lib/silcclient/command.c.
1593 * Changed PING to not accept any arguments. The specs
1594 says that client can ping only the connected server so
1595 requiring an argument is not needed. Affected file is
1596 lib/silcclient/command.c.
1598 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Fixed a fatal bug in private message sending and reception
1601 encryption and decryption when using private message keys.
1602 The implementation was incorrect and did not follow the
1603 specification. It causd that some of the message were
1604 lost since it did not use the sending and receiving keys
1605 as the protocol suggests. This has been fixed and will cause
1606 incompatibilities with older clients when sending private
1607 message encrypted with private message keys. Affected files
1608 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1609 and various other in Irssi SILC Client.
1611 Added `responder' boolean argument to the functions
1612 silc_client_add_private_message_key[_ske] to indicate when
1613 the key is added as responder or initiator of the key
1616 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Removed the silc_ske_check_version function and created
1619 a SilcSKECheckVersion callback. Added also a function
1620 silc_ske_set_callbacks that is now used to set all SKE
1621 callbacks. The callback functions are not given to
1622 the SKE functions anymore, but this function is used to
1625 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1627 * Added `silc_version' argument to the silc_client_alloc
1628 to define the version of the application for the library.
1629 The library will use the version string to compare it
1630 against the remote host's (usually a server) version
1631 string. Affected file lib/silcclient/silcapi.h
1633 * Added the KE protocol context to Key Agreement context
1634 in client library so that we can abort the SKE if it
1635 is in process when we get timeout. Affected file is
1636 lib/silcclient/client_keyagr.c.
1638 * Do not resolve the client ID forever if it returns in the
1639 first time that such client does not exist. This was done
1640 for example with private message. Affected file is
1641 lib/silcclient/client_prvmsg.c.
1643 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1645 * Do not add regex.h for WIN32. The affected file
1646 includes/silcincludes.h.
1648 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1649 not work yet 100%. It generates the DLL's automatically
1650 when compiling with --with-win32 under cygwin.
1652 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * lib/contrib/regex.c is not compiled on WIN32.
1656 * Added silc_net_get_socket_opt function to the
1657 lib/silcutil/silcnet.h.
1659 * Added includes/silcwin32.h for WIN32 specific includes
1662 * Do not use ptime structure or any of the posix process
1663 functions on WIN32 in lib/silccrypt/silrng.c.
1665 * Added silc_gettimeofday to provide generic function
1666 for struct timeval on all platforms. Added the function
1667 to lib/silcutil/silcutil.h.
1669 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1671 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1672 library as they clearly belong there. As a plus side we
1673 can make the actual socket connection routines platform
1676 Added also new generic function silc_socket_read and
1677 silc_socket_write (that used to be silc_packet_[read/write].
1678 The implementation of these are platform specific.
1680 * Added WIN32 specific routines of silc_socket_[read/write]
1681 to lib/silcutil/win32/silcwin32sockconn.c.
1683 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Added preliminary support for native WIN32 compilation under
1686 cygwin (using the -mno-cygwin option for GCC) to the
1687 ./configure.in.pre. The --with-win32 now prepares the
1688 compilation for native WIN32.
1690 * Rewrote the SILC Scheduler interface in the file
1691 lib/silcutil/silcschedule.h. The scheduler is now context
1692 based and does not have anymore any global static scheduler.
1693 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1694 and created lib/silcutil/win32 directory for WIN32 based
1697 * Added Unix specific network routines to the
1698 lib/silcutil/unix/silcunixnet.c and the old
1699 lib/silcutil/silcnet.c includes now only generic routines.
1701 Added WIN32 specific network routines to the
1702 lib/silcutil/win32/silcwin32net.c.
1704 * Added Unix specific utility functions from the
1705 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1707 * Added WIN32 SILC Scheduler to the file
1708 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1711 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Do not handle JOIN notify in the server if the target client
1714 is not registered (idata->registered == FALSE). The affected
1715 file is silcd/packet_receive.c.
1717 * Update the nickrec->founder in event_cumode in the Irssi SILC
1718 client. Affected file irssi/src/silc/core/silc-channels.c.
1720 * Fixed the CUMODE_CHANGE notify handling in the server when
1721 server and router are announcing their clients on channels.
1722 Now the mode changes are saved and notified correctly. The
1723 affected file is /silcd/packet_receive.c.
1725 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1726 They really did not replace the cache entry in the ID Cache.
1727 Now they do that. Affected file silcd/idlist.c.
1729 * Fixed the KICK notify handling in the Irssi SILC client to
1730 update the channel records so that the kicked client does not
1731 appear to be on the channel. The affected file is
1732 irssi/src/silc/core/silc-channels.c.
1734 * Always update the conn->current_channel when executing command
1735 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1737 * Fixed the KILL notify handling in Irssi SILC client to remove
1738 the killed client on all channels.
1740 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Fixed the silc_parse_command_line to remove extra spaces
1743 from the start and end of the arguments. Affected file is
1744 lib/silcutil/silcutil.c.
1746 * Cancel and free any active protocol in the function
1747 silc_server_close_connection. Affected file silcd/server.c.
1749 * Cancel and free any active protocol in the function
1750 silc_client_close_connction. Affected file is
1751 lib/silcclient/client.c.
1753 * Do not execute the KILL command for clients that are in
1754 history (ie. they are not in the network). Affected file is
1757 * Fixed KILL notify handling, client does not crash anymore.
1758 Affected file irssi/src/silc/core/silc-channels.c.
1760 * Reduced the default packet buffer size from 2048 to 1024 in
1761 lib/silccore/silcpacket.c.
1763 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1764 counter to the SKE context that is incresed when the SKE library
1765 performs async operation outside the library. If the outside
1766 process frees the SKE context and FREED status will be set
1767 and the library will detect after the sync operation that the
1768 libary is freed. The affected files are
1769 lib/silcske/silcske[_status].[ch].
1771 * Resolve the client entry information in the function
1772 silc_client_channel_message to assure that NULL pointer is not
1773 passed as client entry to the application. */
1775 * Fixed the task timeout calculation to assure that there is
1776 never negative timeouts. The affected file is
1777 lib/silcutil/silcschedule.c.
1779 * Fixed the channel user mode notification sending in server.
1780 It was sent point-to-point to the router (or to server by router)
1781 but it needs to be destined to a channel. The routines now
1782 supports sending the channel user mode notifys to the channels
1783 when announcing clients and channels. Affected files are
1784 silcd/server.c and silcd/packet_receive.c.
1786 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1787 It did not actually replace the old channel entry in the cache.
1788 Affected file lib/silcclient/client_notify.c.
1790 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Fixed a possible crash in silc_packet_send_prepare. It now
1793 assures always that there is enough space in the buffer and
1794 at the tail area of the buffer (for MAC).
1796 Fixed the inbound buffer reallocation in silc_packet_read.
1797 It was old code and did not handle the reallocation correctly.
1800 The affected file is lib/silccore/silcpacket.c.
1802 * Fixed buffer overflow in silc_parse_nickname in the file
1803 lib/silcutil/silcutil.c.
1805 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * make install generates new server keys only if there is not
1810 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1812 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1813 Added check that if the NOREPLY is set then we will not send
1814 the away message. This avoids infinite loop of away messages
1815 if both clients are away. The affected file is
1816 lib/silcclient/client_prvmsg.c.
1818 * Fixed client crash if /NICK was given without arguments.
1819 Affected file lib/silcclient/command.c.
1821 * Server does not send the invite list in INVITE command back
1822 to the client if the list was not altered. Added this notion
1823 to the protocol spec as well. Affected file silcd/command.c.
1825 Fixed possible crash in INVITE command by checking the
1826 value of silc_server_get_client_route command.
1828 * Fixed the INVITE notify type handling. The arguments are now
1829 taken in correct order and client does not crash. The affected
1830 file is irssi/src/silc/core/silc-channels.c.
1832 Removed the "Inviting xxx to channel" message from the
1833 client library away and let the application handle it.
1834 Affected file lib/silcclient/command.c. Added that message
1835 to Irssi SILC client's message formats.
1837 * Fixed CMODE command crash in client. It now checks the
1838 amount of arguments correctly and does not crash. The affected
1839 file is lib/silcclient/command.c.
1841 * Do not create new channel automatically in silc_channels_join
1842 but check whether the channel by that name already exists.
1843 Affected file irssi/silc/core/silc-channels.c.
1845 * Do not send the SERVER_SIGNOFF to router if the disconnected
1846 entity was the router. Affected file silcd/server.c.
1848 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1849 SILC client as it was missing from there.
1851 Added the handling of the KICK notify to the Irssi SILC client
1852 as it was missing. Added "you have been kicked" message to
1853 Irssi SILC client's message modules formats.
1855 Added the handing of the KILL notify to the Irssi SILC client
1856 as it was missing. Added the kill message module formats
1859 The affected file is irssi/src/silc/core/silc-channels.c.
1861 * The router did not save the channel mode the server announced.
1862 Affected file silcd/packet_receive.c.
1864 * Fixed a possible crash in INFO command in server. If the
1865 server did not provide the server info it crashed. Affected
1866 file silcd/command.c.
1868 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1870 * Fixed the GETKEY command in the server to check also the
1871 global list. Otherwise the GETKEY would not work correctly
1872 in normal SILC server. Affected file silcd/command.c.
1874 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Fixed GETKEY crash, it crashed if the command did not succseed.
1878 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1881 is now real and not just an macro interface to GMP.
1883 Removed the entire GMP from the source tree and imported new
1884 NSS MPI library instead. Reason for removing GMP is that it is
1885 extremely large and compiles extremely slow. The NSS MPI
1886 is only a few files and compiles in less than 10 seconds.
1887 The speed is also about the same as GMP. The MPI is imported
1888 to lib/silcmath/mpi.
1890 If the system has GMP installed we will still use the GMP.
1891 If it is not then the NSS MPI will be compiled.
1893 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Merged a long nickname (127 characters long) crash bugfix from
1896 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1898 * Merged a freed memory reference bugfix from Irssi CVS tree.
1899 Affected file irssi/src/core/commands.c.
1901 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Added the server's public key sving and verification to the
1904 server when performing the SKE. This was missing and the
1905 remote server's (or router's) public key was accepted without
1906 checking whether we have it previously or trust it at all.
1907 Affected file silcd/protocol.c.
1909 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * Check in the silc_server_timeout_remote if protocol is active
1912 and make sure that the protocol's final callback is called so
1913 that all memory if freed. Affected file silcd/server.c.
1915 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1917 * silc_server_whois_send_reply crashed the server if the nickname
1918 was 127 characters long. Affected file silcd/command.c.
1920 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Added sanity check to the silc_server_new_client. If the hostname
1923 is provided inside username then check that the provided hostname
1924 really is the same as the resolved one. If the hostname was not
1925 resolved then check it from the public key. Affected file is
1926 silcd/packet_receive.c.
1928 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1929 if the server disconnected us and the connection is not valid
1930 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1932 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1933 the library to the lib/silcutil/silcutil.[ch].
1935 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Close log file after open. Affected file
1938 lib/silcutil/silclog.c.
1940 * Check whether sock == NULL in silc_client_send_packet and return
1941 if it is. Affected file lib/silcclient/silcclient.c.
1943 * Check rec->entry == NULL in the Irssi SILC Client before
1944 sending the channel message. Affecte file is
1945 irssi/src/silc/core/silc-servers.c.
1947 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Merged a splitted window bugfix from Irssi CVS tree. The
1950 affected file is irssi/src/fe-text/textbuffer-view.c.
1952 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1953 It did not print nickname.
1955 * Improved the distributions system a bit.
1957 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1960 irssi/src/fe-text/gui-window.c.
1962 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1963 to in-active server. The affected file is
1964 irssi/src/silc/core/client_ops.c.
1966 * Resolve the client in USERS command reply if the entry does
1967 not have username resolved. The affected file is
1968 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1969 command to WHOIS command to really resolve stuff. The USERS
1970 is not used any more in any critical section so WHOIS can
1971 be used even though it might be slower than IDENTIFY.
1973 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1976 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Changed the protocol API a bit more consistent in the
1979 lib/silccore/silcprotocol.[ch].
1981 * Changed the following headers to ROBODoc format:
1983 lib/silccore/silcpayload.h
1984 lib/silccore/silcprotocol.h
1985 lib/silccore/silcsockconn.h
1987 All core library headers are now formatted.
1989 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Fixed a bug in Irssi SILC client; do not show that you are
1992 server/router operator if you really are not. Affected file is
1993 irssi/src/silc/core/client_ops.c.
1995 * Renamed silc_command_free_payload to silc_command_payload_free.
1996 Affected file lib/silccore/silccommand.h
1998 * Added silcmath.h to include the prototoypes of various routines
1999 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2002 * Changed the following headers to ROBODoc format:
2004 lib/silccore/silcchannel.h
2005 lib/silccore/silccommand.h
2006 lib/silccore/silcid.h
2007 lib/silccore/silcidcache.h
2008 lib/silccore/silcmode.h
2009 lib/silccore/silcnotify.h
2010 lib/silccore/silcpacket.h
2011 lib/silcmath/silcmath.h
2013 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Added checking to the server code not to start the server if
2016 ciphers and stuff are not configured properly. Affected files
2017 silcd/serverconfig.[h] and silcd/server.c.
2019 * Changed the layout of the header files of the public interfaces
2020 in the SILC libraries. The new layout supports ROBODoc
2021 documentation tool (and some others) so that it is easy to create
2022 a library reference manual. All the other headers and source
2023 code must still follow the CodingStyle document. Also source
2024 code must not include these ROBODoc stuffs, only the headers.
2025 Furthermore, all public interface headers must now be named
2026 by using `silc' prefix, example: silcapi.h, silccipher.h.
2027 Some files were renamed due to this. All the other headers
2028 must not be used as public interfaces. I will update the
2029 CodingStyle document later. Changed following headers, so far:
2031 lib/silcclient/silcapi.h
2032 lib/silccore/silcauth.h
2033 lib/silccore/silcprivate.h
2034 lib/silccrypt/silcdh.h
2036 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Removed silc_client_packet_send_flush from the client library
2041 as it is not needed. Affected file lib/silcclient/client.[ch].
2043 * Added printing of message of unresolved authentication method
2044 to the Irssi SILC client. Added it to the module formats.
2045 Removed the same message from the client library.
2047 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * Added new distribution feature, DISTLABEL. Every distribution
2050 can define own preprocessor label that can be used in the
2051 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2052 file distributions, acconfig.h.pre and prepare.
2054 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Added Makefile.defines_int to include the actual definitions
2057 for Makefile.defines.in. Tested the new distribution system,
2058 created distributions and tested installation.
2060 * Added AWAY message printing to the Irssi SILC client. Added
2061 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2063 * Added SCONNECT command to call the SILC's CONNECT command.
2064 Cannot use CONNECT directly since Irssi uses that internally.
2065 Affected file irssi/src/silc/core/silc-servers.c.
2067 Added ACTION local command. It is same as ME command but takes
2068 the channel as mandatory argument.
2070 Rewrote some of the Irssi's help files to suite for SILC
2073 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2075 * Added Makefile.defines[.in] that should for now on be included
2076 in all Makefile.am file in the source tree. That file includes
2077 all common compilation definitions for SILC source tree.
2079 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Minor changes to the ./prepare script to change the package
2082 name according the distribution name to the configure.in.
2084 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Created new distribution system. Added file `distributions'
2087 that defines all the distributions that can be created out of
2088 the SILC source tree. The ./prepare script now reads that
2089 file to determine how to prepare the distributions. The
2090 first argument to the ./prepare is the name of the distribution
2091 and second is the version of the distribution. If given
2092 without arguments it creates the default (toolkit) distribution
2093 with the default version (defined in ./prepare).
2095 All Makefile.am files that are subject to the distributions
2096 are now named as Makefile.am.pre. These are ./Makefile.am
2097 and lib/Makefile.am. Others may be changed later.
2099 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Added invite list, ban list, some key management and connection
2102 error message printing to module formats in the Irssi SILC client.
2104 * Added new silc_client_set_away_message to set the away message
2105 that is back to the person who sent private message. The
2106 affected file lib/silcclient/silcapi.h and the
2107 lib/silcclient/client_prvmsg.c.
2109 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * Fixed the private message sending in the Irssi SILC client,
2112 added local command KEY to the Irssi SILC client.
2114 Added key management and key agreement message formats to the
2115 irssi/src/fe-common/silc/module-formats.[ch].
2117 Added USERS (alias WHO) printing, server/router operator
2118 indication and LIST command printing to the module formats.
2120 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Fixed channel joining notify handling, cumode notify handling
2123 from Irssi SILC client.
2125 * Added SILC specific module-formats to the Irssi SILC client so
2126 that SILC specific message hilighting, colors etc is possible.
2127 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2129 Added channel mode, channel user mode, actions, notices,
2130 whois and whowas printing to the the module-formats.c.
2132 * Fixed a bug in channel deletion in the server. The channel
2133 is not left to the cache even if the channel founder auth mode
2134 is set when there are no users anymore on the channel. Affected
2135 file silcd/server.c.
2137 * The silc_net_localhost now resolves the entire hostname including
2138 the domain name. Affected file lib/silcutil/silcnet.c.
2140 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * Changed the ask_passphrase client operation to be ascynchronous.
2143 It has now a completion callback and a context that the
2144 application must call after it has got the passphrase from
2145 the user. Affected files lib/silcclient/silcapi.h,
2146 lib/silcclient/protocol.c, lib/silcclient/command.c and
2149 Added SilcAskPassphrase callback that the application calls
2150 to deliver the passphrase to the library.
2152 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2153 The public key verification and especially a certificate
2154 verification is asynchronous procedure.
2156 Added new SILC_SKE_STATUS_PENDING status to indicate the
2157 request is pending and a callback will be called to finalize
2160 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2161 indicate that remote end did not send its public key (or
2162 certificate), even though we require it. Added check for this
2163 condition in the SKE. This was a security bug, now fixed.
2165 Defined new SilcSKEVerifyCbCompletion callback that is called
2166 when the verification process is completed.
2168 The affected files lib/silcske/silcske_status.h and
2169 lib/silcske/silcske.[ch].
2171 * Changed the verify_public_key client operation to be async
2172 as well. Defined SilcVerifyPublicKey callback that is used to
2173 indicate the success of the public key verification process.
2175 Changed the server and client to use the new async client
2178 * Changed the Irssi SILC client's internal scheduler to be called
2179 twice as many times as it used to be. As a result the client
2180 should be a bit faster now. Affected file is
2181 irssi/src/silc/core/silc-core.c.
2183 * Added support to Irssi SILC client of asynchronous public key
2184 verification and passphrase inquiry. Affected file is
2185 irssi/src/silc/core/silc-core.c.
2187 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2189 * Do not say "You have left channel %s" in client library.
2190 Moved it to the application. Affected files are
2191 lib/silcclient/command.c and silc/client_ops.c.
2193 * Fixed silc_client_get_clients. Command context was not
2194 duplicated and was freed memory in the callback. Affected
2195 file lib/silcclient/idlist.c.
2197 * Do not say "you are now talking..." on JOIN command in the
2198 client library. The appliation must handle it.
2200 * Do not say ".. changed topic to" in command reply in the
2201 client libary. The application must handle it.
2203 * Fixed TOPIC command sending in the client library.
2205 * Fixed a memory leak in silc_client_command_free in the file
2206 lib/silcclient/command.c.
2208 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * Imported a modified version of Irssi client to the source tree.
2211 The Irssi will be used to create a new client called
2212 Irssi SILC. Imported to irssi/.
2214 Added silc_core_init_finish function to the Irssi. Affected
2215 file irssi/configure.in.
2217 A lot changes in the Makefile.ams around the irssi tree.
2219 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Do not rehash if the new size is same as the old size of the
2222 hash table, in the silc_hash_table_rehash*. The affected file
2223 lib/silcutil/silchashtable.c.
2225 * Replaced hash_table_del_by_context calls from the server
2226 (when channel->user_list and client->channels) to the
2227 hash_table_del as it is sufficient and faster.
2229 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Added silc_hash_table_list, silc_hash_table_get and the
2232 SilcHashTableList structure to provide an alternative way to
2233 traverse the hash table. The affected files are
2234 lib/silcutil/silchashtable.[ch].
2236 * Changed the server's idlist routines to use the hash table
2237 routines to optimize the code.
2239 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Replaced the client entry's `channel' list and channel entry's
2242 `user_list' list to hash tables for optimized lookup. Changed
2243 the code to use the hash table interface around the code.
2244 Affected file lib/silcd/idlist.[ch].
2246 * Added `auto_rehash' boolean argument to the function
2247 silc_hash_table_alloc to indicate whether the hash table should
2248 auto-rehash when it thinks is appropriate time. It will
2249 increase the hash table size if the there is twice as much
2250 entries in the table than the size of the table, and will
2251 decrease the size if there are twice as less entries than
2252 the size of the table.
2254 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2258 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * silc_idcache_purge_by_context deletes the entry now by context
2261 as it is supposed to do. Affected file lib/silccore/idcache.c.
2263 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2264 client is not anymore valid (WHOWAS givens the info) and not
2265 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2267 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Removed the `data' and `data_len' arguments from the ID Cache
2270 interfaces and added `name' argument. ID Cache does not handle
2271 anymore the binary data only a names associated with given ID.
2273 * When hashing a Client ID with silc_hash_id the entire ID is
2274 not hashed anymore, instead only the hash of the Client ID is
2275 hashed. This way we can access the Client ID from the cache
2276 with Client ID but with the hash of the ID (which is a hash of
2277 the nickname) as well without any difference in performance.
2279 Added also silc_idcache_find_by_id_one_ext to do one on one
2280 searching when we have the actual ID. Added also function
2281 silc_hash_client_id_compare. The affected files are
2282 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2284 * When hashing the name associated with a ID it is always done
2285 in lowercase. This way we can access the cache without worrying
2286 about case-sensitivity, even though, for example nicknames are
2289 * Fixed a bug in server with channel message sending. It put
2290 wrong ID type as destination ID. The affected file
2291 silcd/packet_send.c.
2293 * silc_idcache_del_by_context now deletes from all hash tables
2294 by context. Affected file lib/silccore/idcache.c.
2296 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Changed the client library to use the new ID Cache interface.
2299 Changes around the source tree.
2301 * Added silc_hash_table_rehash_ext to rehash with specific
2302 hash function. Affected file lib/silcutil/silchashtable.[ch].
2304 * Added silc_hash_string_compare to compare two strings in the
2305 hash table. Affected file lib/silcutil/silcutil.[ch].
2307 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Added new function silc_idcache_del_by_context into the
2310 lib/silccore/idcache.[ch].
2312 * Changed the server's ID list routines to use the new ID Cache
2313 interface. Changes around the source tree.
2315 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * Added silc_hash_table_del[_by_context]_ext functions in to the
2318 lib/silcutil/silchashtable.[ch].
2320 Removed silc_hash_table_find_all* routines and added new
2321 silc_hash_table_find_foreach to replace them.
2323 Added silc_hash_table_replace_ext function as extended
2324 replacing function. Separated the simple hash table interface
2325 from the extended hash table interface in the file
2326 lib/silcutil/silchashtable.h.
2328 * Fixed minor bugs and changed it to use some of the new
2329 hash table functions in lib/silccore/idcache.c
2331 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Added new function silc_hash_table_find_all to return all keys
2334 in the hash table by the specified key. As the hash table is
2335 collision resistant it also makes it possible to have several
2336 duplicate keys in the hash table. This function may be used to
2337 find all of the keys from the hash.
2339 Added user_context arguments to the SilcHashFunction,
2340 SilcHashCompare and SilcHashDestructor to deliver user specified
2343 Added new fuctions silc_hash_table_find[_all]_ext to do
2344 extended lookup with specified hash and compare functions and
2345 specified user contexts.
2347 Added new function silc_hash_table_add_ext to add the key
2348 with specified hash function and user context.
2350 Added new function silc_hash_table_foreach to traverse all
2351 entrys in the hash table. Added SilcHashForeach callback
2354 Added new function silc_hash_table_del_by_context to delete
2355 the entry only if the context associated with the key matches.
2357 Affected files are lib/silcutil/silchashtable.[ch].
2359 * Removed silc_hash_[server/client/channel]_id and added just
2360 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2361 silc_hash_id_compare to compare two ID's using as the hash table
2362 comparison function. Added also silc_hash_data to hash
2363 binary data and silc_hash_data_compare to compare it.
2365 * Removed silc_idlist_find_client_by_hash as it is not needed
2366 anymore. Affected file silcd/idlist.[ch].
2368 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2369 to use internally the SilcHashTable. The new ID Cache is a lot
2370 faster than the old one. Some of the ID Cache interface was also
2371 rewritten and obsolete and stupid functions were removed.
2373 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Added entry_count field to the SilcHashTable to keep the number
2376 of the entries in the table. Implemented the function
2377 silc_hash_table_rehash. Added new function
2378 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2380 Fixed a minor bug in silc_hash_table_free.
2382 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2383 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2384 into the lib/silcutil/silcutil.[ch].
2386 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Implemented a collision resistant hash table into the
2389 lib/silcutil/silchashtable[ch]. See the header and the source
2390 for the SilcHashTable API.
2392 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Merged dotconf version 1.0.2 into lib/dotconf.
2396 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Do not compile anything in lib/silcsim/* if the SIM support
2399 is not enabled. The tree should now compile without problems
2402 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Compiled the SILC under cygwin. Compiled and tested briefly
2405 without problems. More tests needed. The SIMs didn't compile
2408 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2410 * Fixed possible crash in silc_get_username in the
2411 lib/silcutil/silcutil.c.
2413 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Fixed a va_arg in silc/client_ops.c.
2417 * Oops, RC5 routines were named AES and caused some problems
2418 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2420 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Added new SilcIDIP structure into the lib/silccore/id.h and
2423 replaced the old `ip' fields from all SILC ID's to that type.
2424 This is a step towards IPv6 support.
2426 The silc_id_get_len takes now the ID as an extra argument.
2427 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2428 both IPv4 and IPv6 based ID's.
2430 The affected files are lib/silccore/id.[ch] and other files
2431 around the tree using these routines.
2433 * Removed the ID length arguments in server from various
2434 silc_server_send_notify_* routines -> they are not needed
2437 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Fixed memory leak in silc_encode_pem_file in the file
2440 lib/silcutil/silcutil.c.
2442 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Check minor version as well in the SKE. Affected files are
2445 silcd/protocol.c and lib/silcclient/protocol.c.
2447 * Added --identifier option to the server so that an identifier
2448 can be when creating the public key for the server. Affected
2449 file is silcd/silcd.c.
2451 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2452 lib/silccrypt/silcpkcs.c.
2454 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Register default ciphers and stuff when using -C option with
2457 the server. Affected file sildc/silcd.c.
2459 * Put back the servers public key filename format, it is better
2460 than the new one. For now, the client keys are saved with the
2461 new filename format. The affected file silc/client_ops.c.
2463 * Implemented the Cipher API for the rest of the ciphers that
2464 did not implement it or implemented it the wrong way.
2466 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Register default ciphers and stuff when using the -S option
2469 in the client. Affected file silc/silc.c. Same also when
2470 creating new key pair with -C option.
2472 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Fixed the silc_verify_public_key client operation function to
2475 save the public keys differently. The fingerprint is now
2476 used as filename and not the hostname. This way also the
2477 client keys are saved uniquely and not with hostnames. The
2478 affected file is silc/client_ops.c.
2480 * Trimmed the silc_hash_fingerprint function to remove extra
2481 whitespaces from the end of the fingerprint. The affected
2482 file is lib/silccrypt/silchash.c.
2486 * Added silc_cipher_register_default function to register all
2487 default ciphers. It can be used when configuration files
2488 does not exist and the application does not want any specific
2489 ciphers in any specific order.
2491 The SilcDList is now used as silc_cipher_list dynamically
2492 allocated cipher list. Removed the static list all together
2493 and now all ciphers must be allocated to the dynamic list.
2494 The silc_cipher_alloc routine was changed to check only the
2497 All silc_cipher_* routines that used to return int returns
2500 The affected files lib/silccrypt/silccrypt.[ch].
2502 * The same thing was done to silc_hash_* as for silc_cipher_*
2503 routines. Affected files lib/silccrypt/silchash.[ch].
2505 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2506 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2507 Added also silc_pkcs_[un]register[_default] functions.
2508 Removed the data_context from the PKCS API.
2510 * Added silc_hmac_register_default function to register default
2511 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2512 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2513 to unregister all hmacs at once.
2515 * Register the default ciphers, hash functions, PKCSs and HMACs
2516 if client's configuration file does not exist. The affected
2519 * The client did not load the hash functions from the SIM
2520 modules at all. Added support for this. Affected file is
2521 silc/clientconfig.c.
2523 * When decoding public key with silc_pkcs_public_key_decode, check
2524 the supported algorithm only if PKCS are registered. Affected
2525 file lib/silccrypt/silcpkcs.c. The same was done with the
2526 silc_pkcs_private_key_decode.
2528 * Fixed the SILC List routines to keep the list always in order.
2529 It used to change the list's order when traversing the list but
2530 not it preserves the order. Affected file lib/trq/silclist.h.
2532 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2534 * Added the client library to use the SilcSocketConnection's
2535 reference counter (by silc_socket_dup) to prevent the bug that
2536 the socket object may be freed underneath async operation.
2538 * The name resolv library checking fixes in the configure.in.pre.
2541 * Created new version of the protocol drafts for future
2542 development. The -03 drafts are the ones that will be changed
2543 in the trunk now and the -02 will remain as they are.
2545 * Send list of CUMODE notifys to the router when announcing
2546 the channel users to the router. Affected file silcd/server.c.
2547 If the router receiving channel founder CUMODE for a channel
2548 that already has channel founder it will send CUMODE notify
2549 to the sender to remove the channel founder rights from the
2550 announced client. Affected file silcd/packet_receive.c.
2552 * The CUMODE notify may now use Server ID as well as the entity
2553 who changes the mode. Updated protocool specs.
2555 * Updated INSTALL and README files.
2557 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * New web pages in the http://silc.pspt.fi. The pages was
2564 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Implemented the [DenyConnectin] config section in the server.
2567 Added silc_server_config_denied_conn to check whether incoming
2568 connection is denied. Affected file silcd/serverconfig.[ch].
2570 * Do not check the ports when checking the incoming configuration
2571 data if the port is 0, meaning any. Affected file is
2572 silcd/serverconfig.c.
2574 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Fixed buffer overflow in silc_string_compare in the file
2577 lib/silcutil/silcutil.c.
2579 * Fixed double free in silc_server_command_leave in the file
2582 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Fixed the version checking in the server. Affected file is
2587 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Fixed the configuration data fetching when accepting new
2590 connections in the server. Affected file silcd/server.c.
2592 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Added `sender_entry' argument to the function
2595 silc_server_packet_relay_to_channel so that we can check
2596 whether some destination actually belongs to the same route
2597 the sender belongs (ie, we must not resend the packet to the
2598 sender). Affected file silcd/packet_send.[ch].
2600 * Added `servername' field to the SilcClientEntry in the server
2601 to hold the name of the server where client is from. Affected
2602 file is silcd/idlist.h.
2604 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Moved the channel message encrypting in the router betwen
2607 router connections from silc_server_channel_message to the
2608 silc_server_packet_relay_to_channel since we want to check
2609 whether we have anybody channel before encrypting anything.
2610 Affected files silcd/packet_[receive/send].c.
2612 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Fixed the [AdminConnection] server config section to support
2615 multiple entries. Affected file silcd/serverconfig.c.
2617 * Added support into the server to check the validity of the
2618 incoming connection before executing any KE or authentication
2621 * The connection configuration is now saved to the KE and
2622 connection auth protocol contexts and not fetched anymore in
2623 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2625 * The local hosts listenning address and port is also resolved
2626 now when starting the server. We want to have the socket object
2627 to include the real address and port for the listener. Added
2628 new function silc_net_check_local_by_sock into the files
2629 lib/silcutil/silcnet.[ch].
2631 * Fixed a broadcast bug in server -> do not broadcast if we
2634 * Fixed a routing bug. Do not route broadcast packets ever.
2635 Broadcast packets must be processed always and not routed since
2636 they may be destined to some other host than yourself and thus
2637 would get routed without no good reason. Affected file is
2640 * Added function silc_server_config_is_primary_route to check
2641 whether primary router connection has been configured (a router
2642 configuration that we are initiating). If there is not, we
2643 will assume that there is only two routers in the SILC network
2644 and we will use the incoming router connection as our primary
2645 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2647 * Changed the order of the broadcasting. Broadcast _after_ the
2648 packet has been processed not before. Affected file is
2651 * Fixed a [ClientConnection] parsing bug. The port was never
2652 parsed correctly thus resulting to port 0. Affected file
2653 silcd/serverconfig.c.
2655 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2656 argument and did not set the broadcast packet flag. Affected
2657 file silcd/packet_send.c. Fixed same bug in the function
2658 silc_server_send_notify as well.
2660 * If we receive NEW_ID packet for our own ID in the server, ignore
2663 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Removed the nickname from the Private Message Payload.
2668 Updated the code and the protocol specs.
2670 * Updated protocol specs for submitting to the IETF.
2672 * Tweaked the Random Number Generator a bit. Affected file
2673 lib/silccrypt/silcrng.c. Exported a new function
2674 silc_rng_[global]_add_noise which can be used to add more
2677 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Do not parse packets with different timeout when protocol
2680 is active -> may cause problem with rekey. Affected file
2683 * When server receives signoff notify it must not create
2684 new channel key if the client is on any channels since the
2685 sender of the signoff notify will create it.
2687 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Added printing of error messages during SKE protocol from the
2690 failure packet sent by server during SKE. Affected file
2693 * Removed the client's failure_callback handling with timeout
2694 and handle it immediately when received.
2696 * The SKE library returned wrong type in SUCCESS and FAILURE
2697 packets. They must be 32 bit MSB not 16 bit MSB.
2699 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Ok, rewrote the logic of the re-key and now it seems to work.
2702 I tested it on high traffic with frequent re-keys without
2703 problems. Added hmac_receive (and renamed hmac to hmac_send)
2704 in SilcClientConnection in lib/silcclient/client.h and
2705 in SilcIDListData in silcd/idlist.h. Also, removed the
2706 SilcPacketParserContext's cipher and hmac fields as they are
2707 not needed anymore and actually caused some problems when
2708 the ciphers and hmac's changed underneath the packet parser.
2710 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * If re-key protocol is active then process the incoming packets
2713 synchronously since we must assure that icoming packets encrypted
2714 with the old key is processed before the new keys is set to
2715 use. This is true other packets than for REKEY packets.
2716 Affected file silcd/server.c. The same was done to client library
2717 as well, affected file lib/silcclient/client.c.
2719 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Fixed bug in client and server to accept the force send if
2722 the packet is send from silc_[server/client]_packet_process
2723 function. Otherwise the packets are never delivered, oops.
2725 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Disable force sending of packets when REKEY protocol is active.
2728 We must assure that no packet is sent directly when rekey is
2729 performed. All packets must be sent through packet queue.
2730 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2731 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2732 function is silc_[server/client]_packet_send_real to check
2735 * Replaced the SIM paths from example config files to
2736 /usr/local/modules. Also, make install creates now
2737 /usr/local/silc/logs directory to hold all the SILC server
2740 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2742 * Made the configure.in.pre work on Solaris. Patch by salo.
2744 * Made all ciphers compatible with non-x86 machines. Defined
2745 CBC mode macros into lib/silccrypt/ciphers_def.h.
2747 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Fixed the make install.
2751 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * When MAC computation fails the silc_packet_decrypt returned 0
2754 even though it was supposed to return -1. Fixed this. The
2755 affected file is lib/silccore/silcpacket.c.
2757 * Do not replace the config files in /etc/silc (in make install)
2758 if they already exist. Affected file ./Makefile.am.
2760 * Do not send re-key packets immediately but through packet queue.
2761 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2763 * Changed silc_net_check_host_by_sock to return FALSE if the
2764 IP/DNS could not be resolved. Though, it returns the IP address
2765 now even if it could not resolve it (but returns also FALSE).
2766 Affected file lib/silcutil/silcnet.[ch].
2768 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Added silc_pkcs_decode_identifier to decode the public key's
2771 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2772 Added also silc_pkcs_free_identifier. Added also new context
2773 SilcPublicKeyIdentifier.
2775 * Added -S option to the silc client. It is used to dump the
2776 contents of the specified public key file.
2778 * Changed the PKCS api to return the public key length when
2779 setting the public key.
2781 * Fixed a fatal bug in the public and private key file loading.
2782 Affected file lib/silccrypt/silcpkcs.c.
2784 * Execute the packet parsing for client with zero (0) timeout
2785 if the protocol is active. Affected file silcd/server.c.
2787 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Made the key generation options to the silcd program. Added
2790 -C option, equivalent to client's option.
2792 * Added new [ServerKeys] config section to the server. It
2793 configures the server's public and private key.
2795 * Defined generic Public Key Payload into the protocol
2796 specification to send specific type of public keys and
2799 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2800 public key or certificate.
2802 * Implemented the GETKEY command to the server and to the
2803 client library and on user interface.
2805 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Made preliminary `make install' work.
2809 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Added SilcServerRekey context into silcd/idlist.h.
2813 * Added the PFS support as defined in the specification to the
2814 SKE protocol. Affected files lib/silcske/*.c.
2816 * Added `ske_group' field to the SilcServerRekey context to hold
2817 the number of the SKE group that is used with PFS in re-key.
2818 Affected file silcd/idlist.h.
2820 * Added PFS re-key support to the server. Affected file is
2823 * Added silc_protocol_cancel to cancel execution of the next
2824 state of the protocol. Affected file is
2825 lib/silccore/silcprotocol.[ch].
2827 * Added the re-key support with and without PFS to the client
2828 library. Re-key is performed once in an hour, by default.
2830 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2831 Added silc_client_rekey_callback and silc_client_rekey_final.
2832 Affected files are lib/silcclient/protocol.[ch] and
2833 lib/silcclient/client.[ch].
2835 * Removed the `hmac_key' and `hmac_key_len' fields from the
2836 SilcClientConnection structure; not needed. Affected file is
2837 lib/silcclient/client.h.
2841 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Do not ask whether user wants to use the negotiated private key
2844 for private messages, just use it. Affected file is
2845 silc/local_command.c.
2847 * Added `send_enc_key' and `enc_key_len' fields to the
2848 SilcIDListData structure since they are needed in the re-key
2849 phase. Affected file is silcd/idlist.[ch].
2851 * Implemented the simple re-key protocol into the server.
2852 Affected files silcd/server.c and silcd/protocol.[ch]. The
2853 re-key will be performed once in an hour, by default.
2855 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2856 Added silc_server_rekey, silc_server_rekey_callback and
2857 silc_server_rekey_final.
2859 * Removed Tunneled flag from the protocol. Updated the code
2860 and the specifications.
2862 * Adde `pfs' field to the SilcIDListData to indicate whether
2863 the PFS is to be performed in the re-key. Affected file is
2866 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2869 int64 of at least the xintXX size. If void * is less that 4
2870 bytes uint32 * will be used. Defined bool as boolean.
2872 * Changed _ALL_ unsigned long and unsigned int to uint32,
2873 unsgined short to uint16 in the source tree.
2875 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2876 not handle clients that has entry->data.registered == FALSE.
2877 They are not in the network anymore. Affected file is
2880 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2882 * Implemented the sending of the SERVER_SIGNOFF notify in the
2883 server. Affected file is silcd/server.c.
2885 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2886 Added also silc_notify_payload_encode_args into the
2887 lib/silccore/silcnotify.[ch].
2889 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2890 Affected file silcd/packet_receive.c.
2892 * Implemented the SERVER_SIGNOFF notify handling in the client
2893 library. Affected file lib/silcclient/client_notify.c. Also,
2894 implemnted the printing of the SERVER_SIGNOFF info to the
2895 application. Affected file silc/client_ops.c.
2897 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2898 if the deleting was successful. Affected file silcd/idlist.[ch].
2900 * Added support for public key authentication in the connection
2901 authentication protocol in the client library. Affected file
2902 lib/silcclient/protocol.c.
2904 * Changed the server's silc_idlist_get_clients_by_* interface
2905 to support already allocated array so that new entries may be
2906 added to pre-allocated array. Affected file silcd/idlist.[ch].
2907 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2908 and command replies.
2910 * All command reply functions in the server now calls the
2911 pending command callback even if error occured. This way the
2912 error will be delivered to the client as well. Affected files
2913 silcd/command.c and silcd/command_reply.c.
2915 * Fixed INFO command to return local server's info if no server
2916 was provided. Affected file lib/silcclient/command.c.
2918 * Removed RESTART command for good. Updated the code and the
2921 * Rewrote parts of the task system. It is a bit simpler now.
2922 Removed unsued task priorities. The affected files are
2923 lib/silcutil/silctask.[ch].
2925 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2927 * Moved the USERS printing from the library to the application.
2928 Affected files lib/silcclient/command.c and silc/client_ops.c.
2930 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Added channel key re-key support. The re-key is perfomed
2935 only by the router and is done once in an hour. Added `rekey'
2936 field to the SilcChannelEntry in the server. Affected files
2937 silcd/server.c and silcd/idlist.h.
2939 * Added silc_task_unregister_by_context into the file
2940 lib/silcutil/silctask.[ch].
2942 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Added SILC_UMODE_GONE mode to indicate when the client is not
2945 present in the SILC network. Added also support to the local
2946 command AWAY that will set this mode. Added support of showing
2947 "xxx is gone" in WHOIS command. The USERS command shows the
2948 gone status as well.
2950 * Fixed setting server and router operator privileges in the
2951 server's UMODE command. Affected file silcd/command.c.
2953 * Merged the SKE KE1 and KE2 payloads into one payload. The
2954 new KE payload is equivalent to the old KE2 payload.
2956 Cleaned up the SKE Start Payload parsing. It now uses the
2957 simple buffer unformatting to do the parsing. A lot faster
2960 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2961 to the SKE that is used to indicate whether both of the SKE
2962 parties should perform authentication. By default only the
2963 responder performs authentication. By setting this flag also
2964 the initiator must do authentication. By default it is unset
2965 since in normal SKE case, client to server connection, only
2966 the responder should do authentication. When doing SKE between
2967 two clients both should perform authentication. Updated the
2968 code and the protocol specs.
2970 * A little fix to IDENTIFY command in the server. Search the
2971 client first by hash not nickname. Affected file is
2974 * Fixed the silc_client_close_connection to support closing
2975 the client to client connections wihtout deleting too much
2976 data. Affected file lib/silcclient/client.c.
2978 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2979 are received if protocol used to be active but is not anymore
2980 the application would crash due to NULL pointer dereference.
2981 Affected files silcd/server.c and lib/silcclient/client.c.
2983 * Added `hash' field to the SilcClientConnection to include
2984 the hash function negotiated in the SKE protocol.
2986 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2987 to set the channel founder authentication data. A client can
2988 claim the founder rights later by providing the authentication
2989 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2990 This way the channel founder can regain the channel founder
2991 privileges even it is left the channel. This works only on
2992 local server and the client must be connected to the same
2993 server to be able to regain the founder rights. Updated the
2994 protocol specs accordingly.
2996 Added support to the CMODE command in the client to set the
2997 founder auth data. Read the README to see how to set it.
2999 Added support to the CUMODE command to claim the founder
3000 rights. Read the README to see how to do it.
3002 Added support for the founder authentication to the Channel
3003 Entry in the server. Affected file silcd/idlist.h.
3005 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3006 server's CMODE command. Affected file silcd/command.c.
3008 * Added the following new functions into lib/silccore/silcauth.[ch]:
3009 silc_auth_get_method and silc_auth_get_data.
3011 * The server now saves the remote hosts public key to the
3012 SilcIDListData pointer. Affected file silcd/protocol.c.
3014 * The normal server now does not remove the channel entry from
3015 the cache if the founder authentication data is set. It used
3016 to remove it if the founder was the last one on the channel on
3017 the server and left the channel. The auth data is saved and
3018 if the channel is re-joined later the old entry is used with
3019 the old auth data. Affected files silcd/command_reply.c and
3022 * Removed the `pkcs' field from the SilcIDListData structure
3023 in the server; it is not used. Affected file silcd/idlist.h.
3025 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Fixed packet processing on slow links. Partial packets were
3028 never re-processed because the incoming data buffer was cleared
3029 by the application. Application must not directly clear the
3030 sock->inbuf, the packet processing routines handle it. Fixed
3031 this in client library and in server.
3033 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Fixed the WHOIS and IDENTIFY send reply function to really
3036 check whether to send list or just one entry. Affected file
3039 * Cleaned up the LEAVE command's channel key distribution. The
3040 affected file silcd/command.c.
3042 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3043 can enforce the channel mode as well. In that case the ID
3044 includes the ID of the server. The code now enforces the
3045 mode change if the router have different mode than the server.
3047 * The notify client operation with CMODE_CHANGE notify can now
3048 return NULL client_entry pointer if the CMODE was not changed
3049 by client. Application must check for this.
3051 * Added <Server ID> argument to INFO command to support server
3052 info fetching by Server ID.
3054 * Added silc_server_announce_get_channel_users to get assembled
3055 packets of channel users of the specified channel. Affected
3056 file silcd/server.[ch].
3058 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3059 was freed underneath the ID Cache.
3061 * Re-announce clients when the server received CHANNEL_CHANGE
3062 notify from the router. Affected file silcd/packet_send.c.
3064 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3067 crashed since it did not handle the fact that there is no cipher
3068 called "3" and didn't check the error condition. Now fixed.
3070 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3071 flag. It can be used to send message requests.
3073 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Implemented the RESTART command in the client.
3077 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3078 notice type messages. Added notice printing to the user
3081 * The channel keys are not re-generated if the channel's mode
3082 is PRIVKEY, ie private key on the channel exists. Affected
3083 files silcd/server.c and silcd/command.c.
3085 * Fixed a little bug in channel message delivery when channel
3086 private keys are set in the server. Affected file is
3087 silcd/packet_send.c.
3089 * Changed the setting on channel->on_channel = TRUE from the
3090 silc_client_save_channel_key to the JOIN command reply. The
3091 key payload is not received if the private channel key is set.
3092 Affected file lib/silcclient/command_reply.c and the
3093 lib/silcclient/client_channel.c.
3095 * When the CMODE_CHANGE notify is sent and the channel private
3096 key mode is removed the channel key must be re-generated in
3097 other cells as well. Added this support for the router in the
3098 silcd/packet_receive.c.
3100 * Added new local command NOTICE to send notice message on
3101 channel. Affected file silc/local_command.[ch].
3103 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Added new local command ME to the client. It is used to send
3106 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3107 some action. Affected file silc/local_command.[ch].
3109 * Changed channel_message and private_message client operations
3110 to deliver the message flags to the application. Added also
3111 the `flags' arguments to the silc_client_send_channel_message
3112 and silc_client_send_private_message functions. Affected file
3115 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Redefined the Private Message Payload to support private message
3118 keys and to support the new private message flags. Updated
3119 the protocol specs. Flags makes it possible to have for example
3120 CTCP style messages.
3122 * Added new type SilcPrivateMessagePayload and defined an API
3123 for it in the lib/silcclient/silcprivate.[ch].
3125 * Tested private message private keys successfully. Tested the
3126 private message key set, unset and list commands with the new
3129 * Redefined the Channel Message Payload to include the channel
3130 message flags (equal with private message flags) to support
3131 for example CTCP style messages.
3133 * Defined some of the message (for channel and private message)
3134 flags. Updated the protocol specs and added the flags to the
3135 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3137 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Added SilcKeyAgreementStatus type to the key agreement routines
3140 to indicate the current status and error if one occured.
3141 The status types are defined in the lib/silcclient/silcapi.h.
3143 * Added new local command KEY that is used to set and unset private
3144 keys for channels, set and unset private keys for private messages
3145 with remote clients and to send key agreement requests and
3146 negotiate the key agreement protocol with remote client. The
3147 key agreement is supported only to negotiate private message keys,
3148 it currently cannot be used to negotiate private keys for channels,
3149 as it is not convenient for that purpose.
3151 * Fixed a minor pending callback setting bug in the function
3152 silc_client_get_client_by_id_resolve, now the function works.
3153 Affected file lib/silcclient/idlist.c.
3155 * Added function silc_net_get_local_port to get local bound
3156 port by socket. Added to lib/silcutil/silcnet.[ch].
3158 * Added `sockets' and `sockets_count' fields to the SilcClient
3159 object. They hold the sockets of the listenning sockets in
3160 the client. Listenning sockets may be for example the key
3161 agreement server. Affected file lib/silcclient/client.[ch].
3162 Added functions the silc_client_add_socket and the
3163 silc_client_del_socket. They are exported to the application
3166 * Added ~./silc/clientkeys to support other client's public keys.
3168 * Renamed verify_server_key client operation to verify_public_key
3169 and added one argument to indicate the type of the connection
3170 (server, client etc.).
3172 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Added silc_server_connection_auth_request to handle the
3175 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3176 silcd/packet_receive.[ch].
3178 * Added silc_server_send_connection_auth_request into the
3179 silcd/packet_send.c to send the connection auth request packet.
3181 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3184 * Fixed the public key authentication in responder side in the
3185 server. The `auth_data' pointer includes the SilcPublicKey
3186 not the path to the public key. Affected file silcd/protocol.c.
3188 * Implemented the public key authentication in the initiator side
3189 in the server. Affected file silcd/protocol.c.
3191 * Removed the [RedirectClient] config section from the server
3192 configuration. Is not needed and I don't want to implement it.
3194 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Cleaned up the CMODE command in the server. It now works
3197 correctly and supports all the modes defined in the protocol.
3198 Affected file is silcd/command.c.
3200 * Added `hmac_name' field to the SilcChannelEntry in the server
3201 to hold the default HMAC of the channel. It can be set when
3202 creating the channel (with JOIN command). Affected files
3205 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3206 type to indicate the change of the current cipher and hmac
3207 on the channel. Client can safely ignore the <cipher> argument
3208 (if it chooses to do so) since the CHANNEL_KEY packet will
3209 force the channel key change anyway. The <hmac> argument is
3210 important since the client is responsible of setting the new
3211 HMAC and the hmac key into use.
3213 * Fixed the CMODE command in the client library as well.
3215 * Tested CMODE command in router environment successfully.
3217 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Show the version of the remote client (or server) when connecting
3220 to the server. It is logged to the log file. Affected file
3221 is silcd/protocol.c.
3223 * Fixed the KILLED notify handling in the client library. The
3224 client must be removed from all channels when receiving the
3227 Also, do not remove the client entry when giving the KILL
3228 command but when the KILLED notify is received.
3230 * Removed silc_idlist_find_client_by_nickname from the server.
3231 Not needed anymore. Affected files silcd/idlist.[ch].
3233 * Implemented the CHANNEL_CHANGE notify type handling to the
3234 server. Affected file silcd/server.c.
3238 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3252 * Added function silc_server_get_client_resolve to find the
3253 client entry by ID from all ID lists and then resolve it
3254 (using WHOIS) if it cannot be found. Affected file is
3257 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Implemented the BAN command to the client library.
3261 * The JOIN command in the server now checks the invite list
3264 * Changed the silc_command_reply_payload_encode_va and the
3265 silc_command_payload_encode_va to support that if argument is
3266 NULL it ignores and checks the next argument. Affected file
3267 lib/silccore/silccommand.c.
3269 * Added silc_server_send_notify_ban to send the BAN notify
3270 type between routers.
3272 * Chaned the silc_notify_payload_encode to support that if
3273 argument is NULL it ignores and checks the next argument.
3274 Affected file lib/silccore/silcnotify.c.
3276 * Tested ban lists in router environment successfully.
3278 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Implemented BAN command to the server, in silcd/command.[ch].
3282 * Removed the BAN and INVITE_LIST modes from the CMODE command
3285 * Added function silc_string_match to regex match two strings.
3286 Affected files lib/silcutil/silcutil.[ch].
3288 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Redefined parts of the SilcChannelEntry in the server to support
3291 the new ban and invite lists.
3293 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Redefined the INVITE command. The same command can be used to
3296 invite individuals to the channel but also to manage the invite
3297 list of the channel (to add to and remove from the invite list).
3298 Updated the protocol specs.
3300 * Added new command SILC_COMMAND_BAN that can be used to manage
3301 the ban list of the channel. Updated the protocol specs.
3303 * Removed the channel modes: the SILC_CMODE_BAN and the
3304 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3305 in the CMODE command. The equivalent features are now available
3306 using INVITE and BAN commands. Updated the protocol specs.
3308 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3309 in the network about change in the current ban list. The notify
3310 type is not used by the client.
3312 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3313 support the invite lists.
3315 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3317 * Added new function silc_string_regexify that converts string
3318 including wildcard characters into regex string that can
3319 be used by the GNU regex library. Added into the file
3320 lib/silcutil/silcutil.[ch].
3322 Added silc_string_regex_combine to combine to regex strings
3323 into one so that they can be used as one regex string by
3324 the GNU regex library. Added into the file
3325 lib/silcutil/silcutil.[ch].
3327 Added silc_string_regex_match to match two strings. It returns
3328 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3330 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Imported GNU regex to the soruce tree into lib/contrib.
3333 Fixed some compiler warning from the regex.c.
3335 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Fixed MOTD command in the server to work in router environment.
3339 * Fixed the MOTD command in the client library to support
3340 the server argument in the command.
3342 * Added `nickname_len' argument to the silc_idlist_add_client
3343 in the server, as the `nickname' argument may be binary data
3346 * Added silc_idlist_get_channels to return all channels from
3349 * Implemented LIST command to the server. Affected file is
3352 * Implemented the LIST command to the client library and on the
3355 * Added [<user count>] argument to the LIST command reply.
3356 With private channels the user count is not shown.
3358 * Updated TODO and README.
3360 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * The client entry's data.registered must be TRUE even with
3363 global client entry on global client list. The data.registered
3364 is used to check whether the client is anymore in the network,
3365 for example with WHOWAS command so it must be valid.
3367 * Fixed the WHOWAS command in the server. It now actually works
3368 in router environment. Added function into silcd/command_reply.c
3369 silc_server_command_reply_whowas_save.
3371 * Added silc_idlist_purge function to the silcd/idlist.c
3372 to periodically purge the ID Cache.
3374 * Fixed INFO command in the server. It works now in router
3375 environment. Added <server name> argument to the INFO command
3376 reply. Updated the protocol specs.
3378 * Fixed minor bug in silc_idcache_purge to not purge if the
3379 expire value is zero.
3381 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3382 they were buggy because of the WHOWAS information.
3384 * Fixed local command MSG to handle the async resolving of
3385 the remote client properly. It used to fail the first MSG.
3386 Affected file silc/local_command.c.
3388 * Added `data_len' field to SilcIDCache context.
3390 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3392 * Update TODO. Todo in commands in the server.
3394 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3397 used by routers as broadcast packet to inform other routers
3398 about the changed user mode.
3400 Implemented the notify handling in the server. Affected file is
3401 silcd/packet_receive.c. Added the function
3402 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3404 * Added new generic Channel Payload and deprecated the New Channel
3405 Payload. The New Channel Payload is now the generic Channel
3408 * Added new argument `mode' to the silc_server_send_new_channel
3409 as it is required in the Channel Payload now.
3411 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3412 and created a new and real SilChannelPayload to represent the
3413 new generic Channel Payload. Implemented the encode/decode
3414 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3416 * Added silc_server_get_client_channel_list to return the list
3417 of channels the client has joined for WHOIS command reply.
3418 Affected file silcd/server.[ch].
3420 * Implemented the channel list sending in the WHOIS command reply
3421 in server and in the client.
3423 Implemented the channel list displaying on the user interface
3424 as well. Affected file silc/client_ops.c.
3426 * Added silc_channel_payload_parse_list to parse list of Channel
3427 Payloads. It returns SilcDList list of SilcChannelPayloads.
3428 Client for example can use this function to parse the list of
3429 channels it receives in the WHOIS command reply. The caller
3430 must free the list by calling silc_channel_payload_list_free.
3431 Affected files lib/silccore/silcchannel.[ch].
3433 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Added one new argument <user mode> to the WHOIS command reply
3436 to return the mode of the user in SILC. Updated the protocol
3439 Implemented it to the server and client.
3441 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Fixed the mode printing on the user interface on joining.
3444 Affected file silc/client_ops.c.
3446 * Implemented the UMODE command and user modes in general to the
3447 client library and to the user interface.
3449 * Implemented the UMODE command to the server.
3451 * The server now sends UNKNOWN_COMMAND error status if client sends
3452 unknown command. Affected file silcd/command.c.
3454 * All server commands now handle the command identifier the right
3455 way when sending the command reply to the client. The client can
3456 use to identify the command replies with the identifier.
3458 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Added silc_server_get_client_route to resolve the route to
3461 the client indicated by the client ID. Affected file is
3464 * Added silc_server_relay_packet as general function to relay
3465 packet to arbitrary destination. This deprecates functions
3466 like _send_private_message_key, _relay_notify etc. Affected
3467 file is silcd/packet_send.[ch].
3469 Removed silc_server_send_key_agreement,
3470 silc_server_send_private_message_key and
3471 silc_server_packet_relay_notify functions from the file
3472 silcd/packet_send.[ch].
3476 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3477 server. Affected file silcd/packet_receive.[ch].
3479 * Implemented the KILL command to the client. Implemented the
3480 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3481 Affected files lib/silcclient/command[_reply].c and
3482 lib/silcclient/client_notify.c. Implemented the KILL notify
3483 printing in the user inteface.
3485 * Fixed a lot silc_parse_nick memory leaks from the client
3486 library in the file lib/silcclient/command.c.
3488 * Changed the silc_server_send_notify_on_channels's `sender'
3489 argument from SilcSocketConnection to SilcClientEntry to
3490 check the sender as entry and not as connection object and not
3491 to send to the client provided as argument. The affected file
3492 is silcd/packet_send.[ch].
3494 * The notify packets that are destined directly to the client used
3495 to not to be processed by the server. Now changed that and the
3496 server processes all notify packets. After relaying the packet
3497 to the client the notify packet is processed in the server.
3499 * The silc_server_free_client_data now checks whether there is
3500 pending outgoing traffic for the client and purges the data to
3501 the network before removing the client entry.
3503 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3506 an client is killed from the SILC Network. Updated the protocol
3509 Added new function silc_server_send_notify_killed to the
3510 silcd/packet_send.[ch].
3512 * Added function silc_server_packet_relay_notify to relay notify
3513 packets that are destined directly to a client. In this case
3514 the server does not process the notify packets but merely relays
3515 it to the client. Affected file silcd/packet_send.[ch].
3517 Added also silc_server_packet_process_relay_notify to check
3518 whereto relay the notify. Affected file is
3519 silcd/packet_receive.[ch].
3521 * Implemented the KILL command to the server.
3525 * Added the backup schema desgined last fall to the protocol
3526 specs for everyone to see. The specification is in the
3527 *-spec-xx.txt draft and the packet type definitions for the
3528 backup routers is in *-pp-xx.txt draft. Thusly, added also
3529 new packet type SILC_PACKET_CELL_ROUTERS.
3531 * A big security problem in the implementation discovered. The
3532 signoff of an client did not cause new channel key generation
3533 which it of course should've done. The channel keys must be
3534 always re-generated when client leaves (or signoffs) the channel.
3535 The silc_server_remove_from_channels funtion now handles
3536 the channel key re-generation.
3538 * Added `sender' argument to the silc_server_send_notify_on_channels
3539 to not to send the client provided as argument. Affected file
3540 silcd/packet_send.[ch].
3542 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Implemented OPER and SILCOPER commands into the server and
3547 * Added silc_auth_verify and silc_auth_verify_data to verify
3548 the authentication directly from the authentication payload.
3549 It supports verifying both passphrase and public key based
3550 authentication. Affected file lib/silccore/silcauth.[ch].
3552 * Added `hash' field to the SilcIDListData structure. It is the
3553 hash negotiated in the SKE protocol. Affected file is
3556 * Slight redesigning of the SilcAuthPayload handling routines.
3557 Do not send SilcPKCS but SilcPublicKey as argument.
3559 * Implemented the public key authentication support to the
3560 serverconfig. The public key is loaded from the provided path
3561 and saved as authentication data to void * pointer. Thus,
3562 changed the unsigned char *auth_data to void *auth_data;
3564 * Fixed SHUTDOWN command to send the reply before the server
3565 is shutdown. :) Affected file silcd/command.c.
3567 * Fixed fatal bug in CONNECT command. The hostname was invalid
3568 memory and server crashed. Affected file silcd/command.c.
3570 * Fixed fatal bug in CLOSE command. The server_entry became
3571 invalid but was referenced later in the command. Affected file
3574 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Fixed fatal bug in failure packet handling. Server ignored
3577 the failure and thus crashed when it came.
3581 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3584 that the command may be executed only once in (about) 2 seconds.
3585 The old SILC_CF_LAG flag is same but allows command bursts up
3586 to five before limiting.
3588 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3589 server code. Various commands now includes the CF_LAG_STRICT
3590 flag to disallow any kind of miss-use of the command.
3592 * Fixed the silc_buffer_unformat to not to allocate any data
3593 if the length of the data is zero. It used to allocate the
3594 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3596 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Changed the format of AdminConnection configuration section
3599 in the server. Added username of the admin to the format.
3600 Affected files silcd/serverconfig.[ch].
3602 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3603 to return admin configuration data by host, username and/or
3606 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * Implemented WHOWAS command to the server. Added the functions:
3610 silc_server_command_whowas_parse,
3611 silc_server_command_whowas_send_reply,
3612 silc_server_command_whowas_from_client and
3613 silc_server_command_whowas_from_server
3615 * Added <Client ID> argument to the WHOWAS command reply. Updated
3616 the protocol specs accordingly.
3618 * Implemented WHOWAS command and command_reply to the client
3621 Implemented the WHOWAS printing on the user interface.
3623 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Added new argument to the WHOWAS command reply, the real name.
3626 It is an optional argument. Updated the protocol specs.
3628 * Added SilcIDCacheDestructor callback that is registered when
3629 the SilcIDCache is allocated. The callback is called when
3630 an cache entry in the ID Cache expires, or is purged from the
3631 cache. Added into lib/silccore/idcache.[ch].
3633 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3634 to destruct the client entries when the cache entry expires.
3635 Other ID Cache's in server and in the client library ignores
3638 * If the ID Cache entry's `expire' field is zero then the entry
3639 never expires. Added boolean `expire' argument to the
3640 silc_idcache_add function in the lib/silccore/idcache.[ch].
3641 If it is TRUE the default expiry value is used.
3643 * Added silc_server_free_client_data_timeout that is registered
3644 when client disconnects. By default for 5 minutes we preserve
3645 the client entry for history - for WHOWAS command.
3647 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Added support to the server to enforce that commands are not
3650 executed more than once in 2 seconds. If server receives
3651 commands from client more frequently, timeout is registered
3652 to process the commands. Affected file silcd/command.c.
3653 Added new function silc_server_command_process_timeout.
3655 * Changed NICK_NOTIFY handling in client library to check that
3656 if the client's nickname was changed, so there is no need to
3657 resolve anything from the server.
3659 * Removed error printing from the WHOIS and IDENTIFY commands.
3660 If error occurs then it is ignored silently in the client library.
3661 The application, however, may map the received error to
3662 human readable error string. The application currently maps
3663 the NO_SUCH_NICKNAME error to string.
3665 * Made the command status message public to the application. Moved
3666 them from lib/silcclient/command_reply.c to
3667 lib/silcclient/command_reply.h. The application can map the
3668 received command status to the string with the
3669 silc_client_command_status_message function.
3671 * Added check to the server to check that client's ID is same
3672 as the Source ID in the packet the client sent. They must
3675 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Added dist-bzip hook to the Makefile.am to make bzip2
3678 compressed distributions.
3680 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Server now enforces the maximum length for the nickname and
3683 the channel as protocol specification dictates. 128 bytes for
3684 nickname and 256 bytes for channel name.
3686 * Moved the WHOIS printing to the application. The client libary
3687 does not print out the WHOIS information anymore, the application
3688 must do it. Renamed silc_client_command_reply_whois_print to
3689 the silc_client_command_reply_whois_save.
3691 The client's idle time is also sent to the application now, and
3692 the idle is shown on screen.
3694 * Added silc_client_command_reply_identify_save to save the
3695 received IDENTIFY entries.
3697 * Do not check for channel private keys in message sending and
3698 reception if the channel does not have the PRIVKEY mode set.
3699 Affected file lib/silclient/client_channel.c.
3701 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3704 just surfaced after chaning the JOIN procedure.
3706 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added silc_client_get_clients_by_list to get client entries
3709 from Client ID list, that is returned for example by JOIN
3710 and USERS command replies. The application should use this
3711 function for example when JOIN command reply is received to
3712 resolve the clients already on the channel (library does not
3713 do that anymore as USERS command reply is not used in the JOIN
3714 procedure anymore). Affected files lib/silcclient/silcapi.h and
3715 lib/silcclient/idlist.c.
3717 * JOIN command reply and USERS command reply returns now SilcBuffer
3718 pointers instead of unsigned char pointers when returning
3719 the client list and mode list.
3721 * Added <Client ID> argument to the JOIN command reply, mainly
3722 for the server to identify for which client the command was
3723 originally sent. Updated protocol specs accordingly.
3725 * Added SilcDlist private_key pointer to the SilcChannelEntry
3726 in the client to support the channel private keys. Affected
3727 file is lib/silcclient/idlist.h.
3729 * Added SilcChannelPrivateKey argument to the function
3730 silc_client_send_channel_message so that application can choose
3731 to use specific private ke if it wants to. If it is not provided,
3732 the normal channel key is used, unless private keys are set.
3733 In this case the first (key that was added first) is used
3734 as the encryption key.
3736 * Implemented the support for channel private key handling.
3737 Implemented the following functions:
3739 silc_client_add_channel_private_key,
3740 silc_client_del_channel_private_keys,
3741 silc_client_del_channel_private_key,
3742 silc_client_list_channel_private_keys and
3743 silc_client_free_channel_private_keys
3745 Affected file lib/silcclient/client_channel.c.
3747 * Added the support for the private keys in the channel message
3748 sending and encryption and in the message reception and
3749 decryption. Affected funtions are
3750 silc_client_send_channel_message and silc_client_channel_message.
3752 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Added SKE's key verify callback to the client library's
3755 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3757 * Removed the statement that server (or router) must send USERS
3758 command reply when joining to the channel so that the client
3759 knows who are on the channel. Instead, the client list and
3760 client's mode list is now sent in the JOIN command reply to the
3761 client who joined channel. This is better solution.
3763 * Added function silc_server_get_users_on_channel and function
3764 silc_server_save_users_on_channel to the silcd/server.[ch].
3766 * Removed function silc_server_command_send_users from the
3769 * Do not show topic on the client library anymore. The topic is
3770 sent in the command reply notify to the application and the
3771 application must show the topic now.
3773 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Added client searching by nickname hash into the IDENTIFY and
3776 WHOIS commands in the server as they were clearly missing from
3777 them. Affected file is silcd/command.c.
3779 * Fixed a bug in private message receiving in the client library.
3780 The remote ID was freed and it wasn't supposed, now it is
3783 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Minor fix to the channel payload; allocate the data area, as it
3786 needs to be of specific length.
3788 * If the key agreement port is zero then the operating
3789 system will define the bound port. Affected files are
3790 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3792 * Added new function silc_channel_payload_decrypt into the file
3793 lib/silccore/silcchannel.[ch].
3795 * Moved the channel message etc, check from silc_packet_decrypt
3796 to applications. The library calls now a generic
3797 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3798 when the packet is either normal or special. This was done to
3799 allow more wide range of checking that was not allowed when
3800 the code was in library. Now applications can do virtually any
3801 checks to the packet and return to the library the decision how
3802 the packet should be processed. Affected files are
3803 lib/silccore/silcpacket.[ch].
3805 Added silc_server_packet_decrypt_check to the server and
3806 silc_client_packet_decrypt_check to the client library.
3808 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3809 to send with specified source and destination information.
3811 * Channel message delivery between routers was broken after the
3812 channel key distribution was fixed earlier. The channel key
3813 was used be to distributed to other routers as well which is not
3814 allowed by the protocol. Now this is fixed and channel keys
3815 really are cell specific and the channel message delivery between
3816 routers comply with the protocol specification.
3818 * Fixed various commands in server to check also the global list
3819 for the channel entry and not just the local list. The affected
3820 file silcd/command.c.
3822 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Added assert()s to buffer formatting and unformatting routines
3825 to assert (if --enable-debug) when error occurs. Affected
3826 file: lib/silcutil/silcbuffmt.c.
3828 * Changed to auto-reconnect to check whether the remote host is
3829 router and register the re-connect timeout if it is. It used
3830 to check that whether we are normal server, but router must do
3831 auto-reconnect with another router as well. Affected file
3834 * Removed the [<key len>] option from CMODE command as the cipher
3835 name decides the key length, nowadays. See the defined ciphers
3836 from the protocol specification.
3838 * Added [<hmac>] option to the CMODE command to define the HMAC
3839 for the channel. Added SILC_CMODE_HMAC channel mode.
3841 * Added [<hmac>] option for the JOIN command so that user can
3842 select which HMAC is used to compute the MACs of the channel
3845 * Added Hmac field to the Channel Message Payload. The integrity
3846 of plaintext channel messages are now protected by computing
3847 MAC of the message and attaching the MAC to the payload. The
3848 MAC is encrypted. Now, it is clear that this causes some
3849 overhead to the size of the packet but rationale for this is that
3850 now the receiver can verify whether the channel message decrypted
3851 correctly and also when private keys are set for the channel the
3852 receiver can decrypt the packet with several keys and check from
3853 the MAC which key decrypted the message correctly.
3855 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3856 lib/silccrypt/silccipher.[ch].
3858 * Added silc_hash_len to return the digest length into the
3859 lib/silcrypt/silchash.[ch].
3861 * Rewrote parts of Silc Channel Payload interface in the
3862 lib/silccore/silcchannel.[ch]. The encode function now also
3863 encrypts the packet and parse function decrypts it.
3865 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Fixed a minor formatting bug in the SKE's key material processing.
3868 It actually might have processed the keys wrong way resulting
3871 * Redefined the mandatory HMAC algorithms and added new algorithms.
3872 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3873 and hmac-md5 truncated to 96 bits. The mandatory is now
3874 hmac-sha1-96. Rest are optional (including the one that used
3875 to be mandatory). Rationale for this is that the truncated HMAC
3876 length is sufficient from security point of view and can actually
3877 make the attack against the HMAC harder. Also, the truncated
3878 HMAC causes less overhead to the packets. See the RFC2104 for
3881 * Added new [hmac] configuration section. The SKE used to use
3882 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3883 is of course wrong. The official names that must be proposed in
3884 the SKE are the ones defined in the protocol specification
3885 (hmac-sha1-96 for example). The user can configure any hmac
3886 using any hash function configured in the [hash] section. At
3887 least, the mandatory must be configured.
3889 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3891 * Added HMAC list to the SKE proposal list. It has now both
3892 hash algorithm list and HMAC list. This makes the protocol
3893 incompatible with previous versions. The SKE now seems to work
3894 the way it is supposed to work, for the first time actually.
3896 * Defined plain Hash algorithms to the protocol specification.
3899 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Implemented support for key agreement packets into the server.
3902 Added functions silc_server_key_agreement and
3903 silc_server_send_key_agreement. Other than these functions,
3904 server has nothing to do with this packet.
3906 * Added support for private message key packets into the server.
3907 Added functions silc_server_private_message_key and
3908 silc_server_send_private_message_key.
3912 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3913 called in the protocol's final callback instead in the END
3914 protocol state. This makes a little more sense and in the same
3915 time in client we can use the same protocol routines for normal
3916 key exchange and to key agreement packet handling as well.
3918 * Added to both client's and server's KE protocol context the
3919 SilcSKEKeyMaterial pointer to save the key material. We will
3920 bring the key material to the protocol's final callback by doing
3921 this. The final callback must free the key material.
3923 * Added SKE's packet_send callback into client's KE protocol
3924 context so that the caller can choose what packet sending function
3925 is used. This way we can use different packet sending when
3926 doing normal SKE when doing key agreement packet handling (in
3927 the key agreement packet handling we do not want to encrypt
3930 * Implemented the responder side of the key agreement routines
3931 in the client. The client can now bind to specified port and
3932 accept incoming key negotiation. The key material is passed
3933 to the application after the protocol is over.
3935 * Implemented the processing of incoming Key Agreement packet
3936 in the client. Added function silc_client_key_agreement to
3939 * Implemented the intiator side of the key agreement routines
3940 in the client. The client can now initiate key agreement with
3941 another remote client. The key material is passed to the
3942 application after the protocol is over.
3944 * Created client_keyagr.c to include all the key agreement
3947 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3948 SILC_TASK_CALLBACK except that it is not static.
3950 * Created client_notify.c and moved the Notify packet handling
3951 from the client.[ch] into that file.
3953 * Created client_prvmsg.c and moved all private message and
3954 private message key routines from the client.[ch] into that file.
3956 * Create client_channel.c and moved all channel message and
3957 channel private key routines from the client.[ch] into that file.
3959 * Changed silc_client_get_client_by_id_resolve to resolve with
3960 WHOIS command instead of IDENTIFY command, in the file
3961 lib/silclient/idlist.c.
3963 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Implemented the SKE's responder side to the Client library.
3967 * When FAILURE is received to the protocol do not trust it
3968 blindly. Register a timeout to wait whether the remote closes
3969 the connection as it should do it, only after that process the
3970 actual failure. This was changed to both client and server.
3972 * Added client_internal.h to include some of the structures
3973 there instead of client.h in lib/silcclient/.
3975 * Added function silc_task_unregister_by_callback to unregister
3976 timeouts by the callback function.
3978 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Some "Incomplete WHOIS info" errors has been appearing on the
3981 log files. Took away the entry->userinfo check from WHOIS
3982 reply sending. The entry->userinfo is now " " if client did not
3983 provide one. I thought this was fixed earlier but something
3984 is wrong still. Let's see if the error still appears.
3986 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Fixed a minor bug in the login when the channel key is
3989 re-generated in the server. It used to generate the key in
3990 wrong order and thus caused problems in the channel traffic.
3992 * Fixed a minor bug in channel key distsribution after
3993 KICK command. The key was not sent to the router even though
3996 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Added silc_ske_process_key_material_data as generic routine
3999 to process any key material as the SILC protocol dictates. The
4000 function is used by the actual SKE library but can be used by
4001 applications as well. This relates to the private message keys
4002 and the channel private keys since they must be processed the
4003 same way the normal SILC session keys. The protocol dictates
4004 this. Affected files: lib/silcske/silcske.[ch].
4006 Added also silc_ske_free_key_material to free the
4007 SilcSKEKeyMaterial structure.
4009 * Defined silc_cipher_set_key function to set the key for
4010 cipher without using the object's method function. The affected
4011 files: lib/silccrypt/silccipher.[ch].
4013 * Implemented silc silc_client_add_private_message_key,
4014 silc_client_add_private_message_key_ske,
4015 silc_client_del_private_message_key,
4016 silc_client_list_private_message_keys and
4017 silc_client_free_private_message_keys functions in the
4020 Added functions silc_client_send_private_message_key to send
4021 the Private Message Key payload and silc_client_private_message_key
4022 to handle incoming Private Message Key payload.
4024 * Added Cipher field to the Private Message Key payload to set
4025 the cipher to be used. If ignored, the default cipher defined
4026 in the SILC protocol (aes-256-cbc) is used.
4028 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Removed lib/silcclient/ops.h file.
4032 Redefined parts of the SILC Client Library API. Created new
4033 file silcapi.h that deprecates the ops.h file and defines the
4034 published Client Library API. Defined also private message key
4035 API and channel private key API into the file.
4037 This is the file that the application must include from the
4038 SILC Client Library. Other files need not be included by
4039 the application anymore.
4041 * Added new key_agreement client operation callback and also
4042 defined the Key Agreement library API for the application.
4044 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4047 is used by clients to request key negotiation between another
4048 client in the SILC network. If the negotiation is started it
4049 is performed using the SKE protocol. The result of the
4050 negotiation, the secret key material, can be used for example
4051 as private message key.
4053 Implemented the Key Agreement payload into the files
4054 lib/silccore/silauth.[ch].
4056 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Redefined ciphers for the SILC protocol. Added some new ciphers
4059 and defined the key lengths for the algorithms. Changed the
4060 code accordingly. The default key length is now 256 bits.
4062 * Fixed SKE key distribution function silc_ske_process_key_material
4063 when the key length is more than 128 bits. The default key
4064 length in SILC is now 256 bits.
4066 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4067 to indicate unsupported algorithm.
4069 * Renamed rijndael.c to aes.c and all functions as well.
4071 * Fixed a long standing channel key setting bug in client library.
4072 Weird that it has never surfaced before.
4074 * Fixed bug in channel deletion. If the entire channel is removed
4075 then it must also delete the references of the channel entry
4076 from the client's channel list as the client's channel entry and
4077 the channel's client entry share same memory.
4079 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Implemented CONNECT and SHUTDOWN commands in the client.
4083 * Implemented CLOSE command to the client.
4085 * Added the function silc_idlist_find_server_by_name into the
4086 files silcd/idlist.[ch].
4088 Added the function silc_idlist_find_server_by_conn into the
4089 files silcd/idlist.[ch].
4091 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * DIE command was renamed to SHUTDOWN. Updated the both code
4096 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4097 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4099 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4102 * Added function silc_server_create_connection function to create
4103 connection to remote router. My server implementation actually
4104 does not allow router to connect to normal server (it expects
4105 that normal server always initiates the connection to the router)
4106 so the CONNECT command is only good for connecting to another
4109 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4112 or some other client was kicked from the channel.
4114 Implemented the handling of the notify type to both client
4117 Implemented silc_server_send_notify_kicked to send the KICKED
4118 notify. It is used to send it to the server's primary router.
4120 * Implemented the KICK command into server and client.
4122 * Added `query' argument to the silc_idlist_get_client function
4123 to indicate whether to query the client from server or not if
4126 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4127 to indicate that the client is not channel founder.
4131 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Removed the rng context from SilcPacketContext structure and
4134 changed that the packet routine uses the Global RNG API.
4136 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Added support for quit message that client can "leave" on the
4139 channel when it quits the SILC. It is ditributed inside the
4140 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4142 Added silc_server_free_client_data that will take the
4143 signoff message as argument.
4145 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4147 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Updated parts of the protocol specification to keep it up
4152 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4155 payloads in one packet.
4157 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4158 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4159 use now the new List flag.
4161 * Also deprecated the following packet types: REPLACE_ID,
4162 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4164 * Added list support for Notify packet in server.
4166 * Added silc_server_send_notify_channel_change to send the
4167 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4168 the silc_server_send_replace_id.
4170 * Added silc_server_send_notify_nick_change to send the
4171 NICK_CHANGE notify type. Deprecates the function
4172 silc_server_send_replace_id.
4174 * Added silc_server_send_notify_join to send the JOIN notify type.
4175 Deprecates the function silc_server_send_new_channel_user.
4177 * Added silc_server_send_notify_leave to send LEAVE notify type.
4178 Deprecates the function silc_server_send_remove_channel_user.
4180 * Added silc_server_send_notify_cmode and
4181 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4182 types. Deprecates the silc_server_send_set_mode function.
4184 * Added SERVER_SIGNOFF notify type to indicate that server has
4185 quit. This means that all clients on the channel from that
4186 server will drop. This can be also used when netsplit happens.
4188 Deprecated REMOVE_ID packet type since it is not needed anymore
4191 Added silc_server_send_notify_server_signoff to send the
4192 SERVER_SIGNOFF notify type. Deprecates the function
4193 silc_server_send_remove_id.
4195 Added also silc_server_send_notify_signoff to send the
4196 SIGNOFF notify type.
4198 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4199 SILC protocol from this day on. Changed the protocol
4200 specification as well.
4202 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4203 notify type. It is used between routers to notify about
4204 topic changes on a channel.
4206 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4209 * Partly updated the protocol specification to comply with the
4210 changes now made. It is still though a bit outdated.
4212 * The JOIN notify type now takes one extra argument <Channel ID>.
4213 The packet used to be destined to the channel but now the
4214 JOIN type may be sent as list thus it is impossible to
4215 destine it to any specific channel. By adding this argument
4216 it is again possible.
4218 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Added CREDITS file. The CHANGES and CREDITS file will appear
4221 in the distribution as well.
4223 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4226 types in the server's silcd/packet_receive.c.
4228 * Implemented CMODE and CUMODE to work in router environment.
4230 * Fixed minor encoding and decoding buglet from the
4231 lib/silccore/silcmode.c.
4233 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4236 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4238 * Changed all SilcConfigServer* and silc_config_server* to
4239 SilcServerConfig* and silc_server_config*, respectively.
4242 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Associated the ID (client or server ID) to the Authentication
4245 Payload to avoid any possibility of forging. Updated the
4246 protocol specification and the code accordingly.
4248 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * The RSA key length is now save to the RsaKey context in the
4251 key generation process in lib/silccrypt/rsa.c. The key length
4252 is now used to figure out the maximum size of the block allowed
4253 to be encrypted/signed.
4255 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4256 is equivalent to the silc_mp_mp2bin but does not allocate any
4259 * Changed silc_mp_mp2bin API to take length argument. If it is
4260 non-zero then the buffer is allocated that large. If zero, then
4261 the size is approximated using silc_mp_sizeinbase, which however
4264 * Created Global RNG API which is global RNG that application can
4265 initialize. After initializing, any routine anywhere in the
4266 code (including library) can use RNG without allocating a new
4267 RNG object. This was done to allow this sort of use of the
4268 RNG in code that has no chance to allocate RNG object. All
4269 applications currently allocate this and many routines in the
4270 library use this. Affected file lib/silccrypt/silcrng.[ch].
4272 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4273 it to use the Global RNG API.
4275 * Defined Authentication Payload into protocol specification that
4276 is used during SILC session to authenticate entities. It is
4277 used for example by client to authenticate itself to the server
4278 to obtain server operator privileges.
4280 Implemented this payload into the lib/silccore/silcauth.[ch].
4281 Implemented also routines for public key based authentication
4282 as the new protocol specification dictates.
4284 Moved definitions of different authentication methods from
4285 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4287 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4288 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4289 silc_pkcs_verify_with_hash functions into the file
4290 lib/silccrypt/silcpkcs.[ch].
4292 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * The client entry's userinfo pointer must be always valid.
4295 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4296 will fail since it requires the userinfo. Now, the userinfo
4297 is allocated as "" if actual userinfo does not exist. Actually,
4298 it must exist and it is totally Ok to drop client connections
4299 that does not announce the userinfo. However, we will make
4300 this workaround for now.
4302 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4303 to return the remote port by socket.
4305 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4308 SILC_SERVER_PENDING_EXEC and added an new macro
4309 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4310 data or when error occurs while processing the pending command.
4312 Added new argument `destructor' into silc_server_command_pending
4313 and to the SilcServerCommandPending object. This destructor is
4314 now called after calling the pending callback or if error occurs
4315 immediately. If error occurs the actual pending callback won't
4316 be called at all - only the destructor. The destructor may be
4317 NULL if destructor is not needed.
4319 All this applies for client library code as well. Similar
4320 changes were made there as well for the pending commands.
4322 In the client, the application must now allocate the
4323 SilcClientCommandContext with the silc_client_command_alloc
4326 * Added reference counter to the SilcServerCommandContext. Added
4327 function silc_server_command_alloc and silc_server_command_dup
4330 Same type of functions added to the client library for the same
4333 * Removed the cmd_ident from IDListData away since it is now
4334 global for all connections. It is the command identifier used
4335 in command sending and with pending commands. The affected file
4338 * Added reference counter to the SilcSocketConnection objecet to
4339 indicate the usage count of the object. The object won't be
4340 freed untill the reference counter hits zero. Currently only
4341 server uses this, and client ignores it. The client must be
4342 set to use this too later. The affected files are
4343 lib/silccore/silcsockconn.[ch]. Added also the function
4344 silc_socket_dup to increase the reference counter.
4346 This was mainly added because it is possible that the socket
4347 is removed underneath of pending command or other async
4348 operation. Now it won't be free'd and proper DISCONNECTING
4349 flags, etc. can be set to avoid sending data to connection that
4350 is not valid anymore.
4352 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4353 the connection. After that it sets SILC_SET_DISCONNECTED.
4354 It is, however, possible that the socket data is not still freed.
4355 The silc_server_packet_process now checks that data is not
4356 read or written to connection that is DISCONNECTED. The socket
4357 get's freed when the reference counter hits zero.
4359 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Changed the client operation API: channel_message operation's
4362 `sender' is now the client entry of the sender, not the nickname
4363 and the `channel' is the channel entry, not the channel name.
4365 In the private_message operation the `sender' is now also the
4366 client entry of the sender not the nickname.
4368 Affected file is lib/silcclient/ops.h and all applications
4369 using the client operations.
4371 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Moved the calling of ops->connect() from connect_to_server_final
4374 into receive_new_id functin since that is the point when the
4375 client is actually allowed to send traffic to network. The
4376 affected file is lib/silcclient/client.c.
4378 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4381 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4382 (if needs broadcasting) instead of broadcasting the packets one
4383 by one which would make a burst in the network traffic.
4385 * Added `broadcast' argument to the functions in silcd/server.[ch]
4386 silc_server_create_new_channel[_with_id] to indicate whether
4387 to send New Channel packet to primary router.
4389 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Added new function into the silcd/server.[ch] files:
4392 silc_server_create_new_channel_with_id to create new channel with
4393 already existing Channel ID.
4395 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4396 lib/silccore/silcpacket.h. This packet is used t send list of
4397 Set Mode payloads inside one packet. Server uses this to set
4398 the modes for the channels and clients on those channels, that it
4399 announced to the router when it connected to it. The protocol
4400 specification has been updated accordingly.
4402 * The silc_server_new_channel did not handle the packet coming
4403 from normal server as it normally does not send that. However,
4404 when it announces its channels it does send it. Implemented
4405 the support for that.
4407 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4408 into the file lib/silccore/id.h.
4410 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Fixed memory leaks in the functions silc_idlist_del_client,
4413 silc_idlist_del_channel and silc_idlist_del_server in the file
4414 silcd/idlist.c. All of those leaked like a sieve.
4416 * Fixed some small memory leaks in the client's function
4417 silc_client_notify_by_server.
4419 * Added functions into silcd/server.c: silc_server_announce_clients,
4420 silc_server_announce_channels and silc_server_announce_server.
4421 These functions are used by normal and router server to announce
4422 to its primary router about clients, channels and servers (when
4423 router) that we own. This is done after we've connected to the
4426 These functions effectively implements the following packet types:
4427 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4428 and SILC_PACKET_NEW_ID_LIST.
4430 * Added new functions into the silcd/packet_receive.[ch]:
4431 silc_server_new_id_list, silc_server_new_channel_list and
4432 silc_server_new_channel_user_list to handle the incoming
4433 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4435 * Added support of changing Channel ID in the function
4436 silc_server_replace_id. If the server that announces a channel
4437 to the router already exists in the router (with same name but
4438 with different Channel ID), router is responsible to send
4439 Replace ID packet to the server and force the server to change
4440 the Channel ID to the one router has.
4442 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4443 client that the Channel ID has been changed by the router. The
4444 normal server sends this to the client. Client must start using
4445 the new Channel ID as the channel's ID.
4447 Implemented handling of this new type into lib/silcclient/client.c
4448 into the function silc_client_notify_by_server.
4450 * Added new function silc_idlist_replace_channel_id into the files
4451 silcd/idlist.[ch] to replace the Channel ID.
4453 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Call silc_server_command_identify_check always when processing
4456 the IDENTIFY command in silcd/command.c
4458 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4461 send keepalive packets. The packet can be sent by clients,
4462 servers and routers.
4464 Added function silc_socket_set_heartbeat into the file
4465 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4466 If not set, the heartbeat is not performed. The actual
4467 heartbeat is implemented in the low level socket connection
4468 library. However, application is responsible of actually
4471 Added silc_server_send_heartbeat to send the actual heartbeat
4472 packet into silcd/packet_send.[ch]. Server now performs
4473 keepalive with all connections.
4475 * Added silc_task_get_first function into lib/silcutil/silctask.c
4476 to return the timeout task with shortest timeout. There was a bug
4477 in task unregistration that caused problems. TODO has been
4478 updated to include that task system must be rewritten.
4480 * The client library will now resolve the client information when
4481 receiving JOIN notify from server for client that we know but
4482 have incomplete information.
4484 * Rewrote parts of silc_server_remove_from_channels and
4485 silc_server_remove_from_one_channel as they did not remove the
4486 channel in some circumstances even though they should've.
4488 * Encryption problem encountered in server:
4490 The LEAVE command used to send the Channel Key packet to the
4491 router immediately after generating it. However, the code
4492 had earlier sent Remove Channel user packet but not immediately,
4493 ie. it was put to queue. The order of packets in the router
4494 was that Channel Key packet was first and Remove Channel User
4495 packet was second, even though they were encrypted in the
4496 reverse order. For this reason, MAC check failed. Now, this
4497 is fixed by not sending the Channel Key packet immediately but
4498 putting it to queue. However, this is more fundamental problem:
4499 packets that are in queue should actually not be encrypted
4500 because packets that are sent immediately gets encrypted
4501 actually with wrong IV (and thus MAC check fails). So, packets
4502 that are in queue should be encrypted when they are sent to
4503 the wire and not when they put to the queue.
4505 However, the problem is that the current system has not been
4506 designed to work that way. Instead, the packet is encrypted
4507 as soon as possible and left to the queue. The queue is then
4508 just purged into wire. There won't be any fixes for this
4509 any time soon. So, the current semantic for packet sending
4512 o If you send packet to remote host and do not force the send
4513 (the packet will be in queue) then all subsequent packets to the
4514 same remote host must also be put to the queue. Only after the
4515 queue has been purged is it safe again to force the packet
4518 o If you send all packets immediately then it safe to send
4519 any of subsequent packets through the queue, however, after
4520 the first packet is put to queue then any subsequent packets
4521 must also be put to the queue.
4523 Follow these rules and everything works fine.
4525 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added new function silc_server_remove_clients_by_server to
4528 remove all client entries from ID list when the server connection
4529 is lost. In this case it is also important to invalidate all
4530 client entires as they hold the invalid server entry. This
4531 fixes fatal bug when server has lost connection and will reconnect
4534 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Made some sanity checks to silc_server_daemonise like to check
4537 whether the requested user and group actually exists.
4539 * Added sanity check to SKE's silc_ske_responder_finish to check
4540 that the public and private key actually is valid.
4542 * Invalidate the client's nickname when receiving Replace ID
4543 packet and the Client ID is being replaced. This means that the
4544 server will query the nickname if someone needs it (client)
4547 * Sort the ID Cache in client library when the ID Cache data
4548 has changed (needs sorting).
4550 * Do not allow for SILC client to create several connections to
4551 several servers. The client does not support windows right now
4552 and generating multiple connections causes weird behaviour.
4554 Irssi-silc client does support windows and can handle several
4555 connections without problems, see: www.irssi.org and SILC plugin.
4557 * Fixed some places where client was added to the IDList. The
4558 rule of thumb is following (in order to get everything right):
4559 If the client is directly connected local client then the
4560 `connection' argument must be set and `router' argument must be
4561 NULL to silc_idlist_add_client function. If the client is not
4562 directly connected client then the `router' argument must
4563 bet set and the `connection' argument must be NULL to the
4564 silc_idlist_add_client function.
4566 * The funtion silc_server_packet_send_local_channel actually did
4567 not check whether the client was locally connected or not. It
4568 does that now. Fixed a bug related to LEAVE command.
4570 * Fixed Remove Channel User payload parsing bug in server's
4571 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4573 * The server's silc_server_save_channel_key now checks also the
4574 global ID list for the channel as it might not be in the local
4575 list. Fixed a bug related to LEAVE command.
4577 * Is this the end of the [<unknown>] buglet that has been lurking
4578 around for a long time? A little for loop fix in server's
4579 silc_server_command_whois_parse that is used by both IDENTIFY
4580 and WHOIS command. At least, this was a clear bug and a cause
4581 of one type of [<unknown>] buglet.
4583 * WHOIS and IDENTIFY commands call the function
4584 silc_server_command_[whois/identify]_check function even if
4585 we are not router server.
4587 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Added --with-gmp configuration option. If set the GMP
4590 is always compiled in the SILC source tree. If not set then
4591 it is checked whether the system has the GMP3 installed. If
4592 it has then the GMP won't be compiled (the system's headers
4593 and library is used), if it doesn't have it then the GMP is
4594 compiled in the SILC source tree.
4596 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Changed RSA private exponent generation to what PKCS #1
4599 suggests. We try to find the smallest possible d by doing
4600 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4601 not security fix but optimization.
4603 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added new config entry [Identity] to fork the server and run
4606 it as specific user and group. A patch from Bostik.
4608 * Imported Dotconf configuration library into lib/dotconf.
4609 This will be used to create the SILC configuration files later.
4610 It will appear in the distsribution after this commit.
4612 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * A big code auditing weekend happening. Auditing code for
4615 obvious mistakes, bugs and errors. Also, removing any code
4618 Removed files for being obsolete:
4620 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4621 inline in the file lib/silcutil/silcbuffer.h)
4623 o lib/silcutil/silcbufutil.c (the header has inline versions)
4625 Changed code to fix possible error conditions:
4627 o The buffer formatting routines now check that the destination
4628 buffer really has enough space to add the data. This applies for
4629 both buffer formatting and unformatting
4630 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4631 unformatting was changed to accomodate following rules:
4632 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4633 sent to the function while XXX_*STRING will not allocate or copy
4634 the data into the buffer. Instead it sets the pointer from the
4635 buffer into the pointer sent as argument (XXX_*STRING used to
4636 require that the pointer must be allocated already). This change
4637 makes this whole thing a bit more consistent and more optimized
4638 (note that the data returned in the unformatting with XXX_*STRING
4639 must not be freed now). The routines return now -1 on error.
4641 o Tried to find all code that use buffer_format and buffer_unformat
4642 and added return value checking to prevent formatting and
4643 especially unformatting errors and possible subsequent fatal
4646 o Changed ske->x and ske->KEY to mallocated pointers in
4647 lib/silcske/silcske.h. Fixed possible data and memory leak.
4649 o Added return value checking to all *_parse* functions. Fixed
4650 many memory leaks as well.
4652 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4653 so that buffer overflows would not happen. All code now also
4654 checks the return value as it can fail.
4656 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Added reconnection support to server if the normal server looses
4659 its connection to the router (for example if router is rebooted).
4660 The server performs normal reconnection strategy implemented
4661 to the server. Affected file silcd/server.c.
4663 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Added new packet type SILC_PACKET_SET_MODE that is used to
4666 distribute the information about changed modes (for clients,
4667 channels and clients channel modes) to all routers in the
4668 network. Updated the protocol specification accordingly.
4670 Added functions into silcd/packet_send.c and
4671 silcd/packet_receive.c: silc_server_send_set_mode,
4672 silc_server_set_mode.
4674 Added new files silcmode.[ch] into lib/silccore that implements
4675 the encoding and decoding of Set Mode Payload. Added new type
4676 SilcSetModePayload. Moved the definitions of different modes
4677 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4679 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Oops, a little mistake in server's connection authentication
4682 protocol. The protocol is not ended with FAILURE but with
4683 SUCCESS if the authentication is Ok. :) Affected file is
4686 * Implemented NICK_CHANGE notify handling in server in the file
4687 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4688 the local clients on the channel. After the changing nickname
4689 in router environment snhould work and the [<unknown>] nickname
4690 should appear no more.
4692 The silc_server_replace_id function that receives the Replace ID
4693 payload now sends the NICK_CHANGE notify type also in the file
4694 silcd/packet_receive.c
4696 * Changed WHOIS and IDENTIFY command to support the maximum amount
4697 of arguments defined in protocol specs (3328 arguments). This
4698 fixed a bug that caused problems when there were more than three
4701 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added extra parameter, command identifier, to the
4704 silc_client_send_command so that explicit command identifier
4707 Changed that ID list routines uses specific command identifier
4708 when sending WHOIS/IDENTIFY requests to the server so that they
4709 can be identified when the reply comes back.
4711 Affected files lib/silcclient/command.[ch],
4712 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4714 * Added `sender' argument to silc_server_packet_send_to_channel
4715 to indicaet the sender who originally sent the packet to us
4716 that we are now re-sending. Ignored if NULL. Affected file
4717 silcd/packet_send.[ch].
4719 * Added some server statistics support in silcd/server_internal.h
4720 SilcServerStatistics structure and around the server code. Also
4721 send some nice statistics information when client is connecting
4724 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Fixed channel ID decoding in server's JOIN command reply in
4727 silcd/command_reply.c
4729 * Fixed braodcasting of replace ID payload to not to send it if
4730 we are standalone server in silcd/packet_receive.c.
4732 * Fixed all channel message sending routines to not to send
4733 packets to clients that has router set, since they are routed
4734 separately in the same function earlier. Affects file
4735 silcd/packet_send.c and all channel packet sending functions.
4737 * In USERS reply, res_argv[i] are not allocated, the table
4738 is allocated. Thus changed that free the table, not its
4741 * In server's whois_check and identify_check if the client is
4742 locally connected do not send any WHOIS commands - they are not
4745 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Fixed some minor bugs in client when sending WHOIS command. The
4748 arguments was in wrong order.
4750 * Removed statis function add_to_channel from server in
4751 silcd/command.c that was previously used with the joining but
4754 * Tested USERS command in router environment successfully with two
4755 routers, two servers and two clients.
4757 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Reorganized the USERS command and command reply in client library
4760 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4761 When the command is given by user we register a pending command
4762 callback that will reprocess the command after the reply has been
4763 received from the server. When reprocessing the packet we then
4764 display the information. Thus, the USERS information is displayed
4765 now in the command callback instead of in the command reply
4766 callback. The processing of the command is same as previously
4767 when server has sent the command reply in the JOINing process.
4769 * Added to USERS command in silcd/command_reply.c to join the client,
4770 we didn't use to know about, to the channel after we've created
4771 a client entry for it. Also, for clienet we did know already still
4772 check whether it is on the channel or not and add it if not.
4774 * Removed silc_server_command_join_notify as the function and its
4777 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Changed the client's pending command handling to the same as the
4780 server's pending command handling. It is also now possible to
4781 execute command reply functions from other command reply
4782 function as the function callbacks for commands and command
4783 replies are one and same. The pending commands are not static
4784 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4785 in client connection context. Thus, pending commands are server
4786 connection specific as it is convenient.
4788 Changed the function silc_client_command_pending and
4789 silc_client_command_pending_del and added new function
4790 silc_client_command_pending_check. Removed the
4791 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4794 * Added cmd_ident, current command identifier, to the client
4795 connection context in lib/silcclient/client.h to keep track on
4796 command identifiers used in command sending. Client's command reply
4797 function handling now supports the mandatory command identifiers.
4799 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4800 funtions in client to fully support pending command callbacks.
4802 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4803 as one of the arguments to the application in the command reply
4806 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4807 before first releasing SILC but came back. Now it is removed again
4808 and should come back nomore. The FORWARDED flag was used only
4809 by the JOINing procedure by forwarding the command packet to router.
4810 Now, the JOINing procedure has been changed to more generic (due
4811 to various router environment issues) and FORWARDED is not needed
4812 anymore for anything. The protocol specification is yet to be
4815 Now, removed silc_server_packet_forward from server and the flag
4816 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4818 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Renamed NAMES command to USERS command. The NAMES was named that
4821 due to historical reasons. Now it is renamed. Also, rewrote
4822 parts of the USERS command. The nickname list is not sent anymore
4823 by the server. Only Client ID and mode lists are sent in the USERS
4824 command. Changed this also to the protocol specification.
4826 The client now resolves the names and stuff after it receives
4827 the USERS list from the server when joining to the channel.
4829 * WHOIS and IDENTIFY commands has been changed to support multiple
4830 Client ID's per command. One can now search for multiple users
4831 in the network by sending only one WHOIS or IDENTIFY command.
4832 Changed the code and the protocol specifications.
4834 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4835 uses silc_server_command_whois_parse to parse the request. */
4837 * If normal server, do not parse the WHOIS and IDENTIFY requests
4838 before sending it to the router. Saves some time.
4840 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Fixed JOIN command on client library. Wrong number of arguments
4843 used to crash the client.
4845 * Added silc_server_channel_has_global function to check whether
4846 channel has global users or not.
4848 * Added silc_server_channel_has_local function to check whether channel
4849 has locally connected clients on the channel.
4851 * The silc_server_remove_from_one_channel now checks whether the
4852 channel has global users or not after given client was removed from
4853 the channel. It also checks whether the channel has local clients
4854 on the channel anymore. If it does not have then the channel entry
4855 is removed as it is not needed anymore.
4857 * The silc_server_notify now checks on JOIN notify whether the joining
4858 client is one of locally connected or global. If it is global then
4859 the channel has now global users on the channel and that is marked
4860 to the channel entry. Also, it now saves the global client to
4861 global list who is joining and JOINs it to the channel. This is
4862 for normal server, that is.
4864 Changed silc_server_send_notify_on_channel,
4865 silc_server_packet_relay_to_channel and
4866 silc_server_packet_send_to_channel check if we are normal server
4867 and client has router set (ie. global client) do not send the
4868 message to that client, as it is already routed to our router.
4870 * Implemented LEAVE notify type handling in silc_server_notify
4873 * Tested LEAVE command in router environment successfully. Tested
4874 with two routers, two servers and two clients.
4878 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4880 * Implemented SIGNOFF notify type handling in silc_server_notify
4883 * silc_server_remove_id now removes the client entry from all channels
4884 it has joined and thusly sends SIGNOFF notify type.
4886 * Rewrote the NAMES list generation in server by removing two excess
4887 loops. The lists are created now inside one loop.
4889 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * silc_server_remove_channel_user checks now also global list
4892 for channel and client.
4894 * silc_server_new_channel_user checks now both local and global
4895 list for channel and client. Fixed a bug in client id decoding.
4896 Used to decode wrong buffer.
4898 * silc_server_channel_message checks now both local and global
4899 list for channel entry.
4901 * Tested channel joining (hence JOIN) in router environment
4902 successfully. Tested with two routers, two servers and two
4905 * Tested channel message sending in router environment successfully.
4907 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Added silc_server_save_channel_key into server.[ch] to save the
4910 received channel key in Channel Key payload processing. It is
4911 also used in JOIN command reply handling.
4913 Equivalent function silc_client_save_channel_key added into
4914 client.[ch] into client library.
4916 * Changed JOIN command reply to send information whether the channel
4917 was created or not (is existing already) and the channel key
4918 payload. Changed protocol specs accordingly.
4920 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4921 the request was sent by ID and not by nickname. Crashed on
4924 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4927 now correctly save the received data.
4929 * silc_server_free_sock_user_data now notifies routers in the
4930 network about entities leaving the network.
4932 At the same time implemented functions silc_server_remove_id
4933 and silc_server_send_remove_id to receive and send REMOVE_ID
4934 packets. The packet is used to notify routers in the network
4935 about leaving entities. The ID removed will become invalid in
4938 * Added function silc_idlist_del_server into server. Removes and
4939 free's server entry from ID list.
4941 * silc_server_private_message function now checks, if we are router,
4942 that the destination ID really is valid ID, naturally.
4944 * In router when NEW_ID packet is received (for new client) the
4945 hash of the Client ID is saved in the ID Cache but the
4946 client->nickname is set to NULL, instead of putting the hash
4949 IDENTIFY command now also checks that client->nickname must be
4950 valid. If it is not if will request the data from the server who
4951 owns the client. Added new function
4952 silc_server_command_identify_check.
4954 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4955 to set the command to already allocated Command Payload.
4957 * Tested private message sending in router environment with two
4958 routers, two servers and two clients. Fixed minor bugs and now
4961 * Fixed segfault from client's NAMES command. Used to crash if
4964 * Forwarded packets must not be routed even if it is not destined
4965 to the receiver. Changed server code comply with this.
4967 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Added `require_reverse_mapping' boolean value to ServerParams
4970 structure. If TRUE (not default) the server will require that
4971 the connecting host has fully qualified domain name.
4973 If the reverse mapping is not required and hostname could not be
4974 found the IP address is used as hostname.
4976 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Implemented version string checking to both client and server.
4979 The check is incomplete currently due to the abnormal version
4980 strings used in development version of SILC.
4982 * Changed all command functions in server to use the new
4985 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Changed char *data to unsigned char *data in ID Cache system to
4988 support binary data as ID Cache data. Changed code to support
4989 binary data in lib/silccore/idcache.c.
4991 * Renamed silc_server_packet_relay_command_reply to
4992 silc_server_command_reply as it is normal packet receiving
4993 function. Rewrote the function to accept command replys for
4994 servers and not only for clients.
4996 * Mark remote router always as registered server if we are connecting
4997 to it. Otherwise, commands sent by the router to us are ignored.
4999 * All ID List find routines now returns the ID Cache Entry pointer
5000 as well if requested.
5002 * WHOIS command works now in router environment, tested with two
5003 routers, two servers and two clients.
5005 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5006 in router environment (as it is almost equivalent to WHOIS) but
5007 hasn't been tested thoroughly. Added new functions:
5009 silc_server_command_identify_parse
5010 silc_server_command_identify_send_reply
5011 silc_server_command_identify_from_client
5012 silc_server_command_identify_from_server
5014 * Disabled route cache adding because adding two different ID's with
5015 same IP replaces the old cache entry thus giving wrong route.
5016 The entry->router->connection is always the fastest route anyway
5017 so route cache may not be needed. Of course, new routes maybe
5018 established after receiving the ID when the entry->router->connection
5019 might not be anymore the most optimal.
5021 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Add route cache for received ID for fast routing.
5025 * Added silc_server_packet_route to route received packet on router
5026 that is not destined to us.
5028 * Renamed silc_server_get_route to silc_server_route_get.
5030 * Added id_string and id_string_len fields into SilcServer to
5031 include encoded ServerID for fast comparing without excess
5032 encoding of the ID's.
5034 * Cleaned up WHOIS command on server side. Added following static
5037 silc_server_command_whois_parse
5038 silc_server_command_whois_check
5039 silc_server_command_whois_send_reply
5040 silc_server_command_whois_from_client
5041 silc_server_command_whois_from_server
5043 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5044 arguments in command replies. All command functions should be
5045 updated to use this macro.
5047 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Minor typo fixes on command reply handling on server.
5051 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Added silc_server_command_add_to_channel internal routine to add
5054 the client to the channel after router has created the channel and
5055 sent command reply to the server.
5057 * Added generic silc_server_send_command to send any command from
5060 * Use static buffer with ID rendering instead of duplicating data.
5062 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Fixed a channel user mode bug when joining to a channel server gave
5065 everybody channel founder rights, oops.
5067 * We mark ourselves as the router of the incoming server connection
5068 if we are router ourselves. This way we can check in some packet
5069 sending functions whether it is locally connected server. For
5070 incoming router connections we put NULL.
5072 * For router sending packets locally means now always sending the
5073 packet cell wide; to local clients and local servers. For normal
5074 server sending packet locally means sending it to only local
5077 * Fixed the JOIN command to really work in router environment. If the
5078 channel is created it is always created by the router. Router is
5079 also responsible of making the initial joining to the channel,
5080 sending JOIN notify to the sending server and distributing
5081 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5082 does not exist server doesn't do anything else but forward the
5083 command to the router which performs everything.
5085 * Added silc_server_send_channel_key function to send the Channel Key
5088 * Added silc_server_create_channel_key to create new channel key. The
5089 channel key is now re-generated everytime someone joins or leaves
5090 a channel, as protocol dictates. Note: channel->key_len is the
5093 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5096 packet_receive.[ch] to separate packet sending and receiving
5097 routines. The server.[ch] now includes everything else including
5098 actual packet processing (writing and reading data) and other
5101 Renamed silc_server_private_message_send_internal to
5102 silc_server_send_private_message. The routine is still though
5103 used only to relay private messages as server does not send
5104 private messages itself.
5106 Renamed silc_server_new_channel to silc_server_create_new_channel
5107 and added new function sicl_server_new_channel that handles the
5108 incoming New Channel packet. Added also new sending function
5109 silc_server_send_new_channel to send New Channel Payload.
5111 * Added new function silc_server_notify to process incoming notify
5112 packet to the server/router. Server may then relay the notify
5113 to clients if needed.
5115 * Added new function silc_server_new_channel_user to process incoming
5116 New Channel User packet. Router will redistribute the packet and
5117 send JOIN notify to its local clients and locally connected servers
5118 if needed. Normal server will send JOIN notify to its local client
5119 on same channel when received this packet. Added also corresponding
5120 sending function silc_server_send_new_channel_user to sent the
5123 * Added boolean route argument to send_notif_to_channel and
5124 packet_send_to_channel functions to attempt to route the packet
5125 if it is TRUE and send only locally if it is FALSE.
5127 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * silc_server_replace_id now broadcasts the received replace ID
5130 packet if it is not broadcast packet already. The router must
5131 broadcast to inform other routers about changed ID.
5133 * Added backpointer to server's router into SilcServer context in
5134 silcd/server_internal.h.
5136 * Fixed silc_server_packet_broadcast to send correct broadcast
5139 * The channel key is now distributed to the local client as soon
5140 as it is received from the router (in router environment) so that
5141 no other packet may be sent for the channel until client has
5144 * silc_server_remove_channel_user now broadcasts the received
5145 Remove Channel User packet if it is not broadcast packet already.
5146 The router must broadcast to inform other routers about removed
5149 * Added users field into SilcPacketContext that is a reference count
5150 of the context. One can increase the reference count by calling
5151 silc_packet_context_dup which is now changed to just increase the
5152 reference count instead of duplicating the data. The reference
5153 count is decresed by calling silc_packet_context_free that will
5154 free the data after the reference count hits zero.
5156 For now on the packet context and everything allocated into it
5157 (including the raw packet from network) must be freed by calling
5158 the new silc_packet_context_free function. Added also new function
5159 silc_packet_context_alloc that must be used now to allocate the
5160 context. This also means that if a routine is asynchronous from
5161 silc_[client/server]_packet_parse_type the packet context must
5162 be duplicated by calling silc_packet_context_dup. Otherwise it
5163 gets free'd after silc_[client/server]_packet_parse_type returns.
5164 Also, one must remember that if packet is duplicated then its
5165 reference count must be decresed by calling the free function as
5166 many times as it was duplicated.
5168 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5169 from both client and server.
5171 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Made joining to a channel working in router environment.
5175 * Cleaned up JOIN command on server side and create function
5176 silc_server_command_join_channel internal routine to make the
5179 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Changed silc_command_pending list to SilcDList. Also, added
5182 `ident' field to SilcServerCommandPending structure to identify
5183 the reply and to call correct callback.
5185 Added silc_server_command_pending_check function to replace the
5186 corresnponding macro. The silc_command_pending list is not
5189 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5190 to set identifier to previously allocated Command Payload. It
5191 is used to set identifier for command when resending Command
5194 * Added silc_command_payload_encode_payload to encode Command
5195 Payload buffer from SilcCommandPayload structure.
5197 * Added silc_argument_payload_encode_payload to encode Argument
5198 payload buffer from SilcArgumentPayload structure.
5200 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Changed WHOIS command to support router connection on server side.
5203 The whois request is always sent to router unless the server is
5204 standalone server. After server has received the reply from the
5205 router will it send the reply to the client.
5207 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5208 broadcast received broadcast packet. The function is used only
5209 by router. The broadcast packet is always sent to the router's
5212 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5213 render given ID to printable string, for log files for example.
5215 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Made basic router to router connections working. At least they
5218 can now connect to each other but nothing really works the way
5219 they are supposed - yet.
5221 * Added new initiator token to RouterConnection configuration
5222 file in silcd/serverconfig.[ch]. It is used to tell whether we
5223 are the initiator to the remote router or whether we'll expect
5224 the other end to connect.
5226 * Moved registering of listener task to silc_server_init, hence
5227 the server starts listenning as soon as it is run, even if it
5228 does not have connections to other routers. Let's see how well
5231 * Changed default connection retry timeouts for more suitable in
5234 * Removed cipher and such arguments from silc_idlist_add_client
5235 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5236 Added new function silc_idlist_add_data to add the keys and stuff
5239 * Added SilcIDListData structure and added it to SilcClientEntry
5240 and SilcServerEntry as their first field in the structure. This
5241 way we can explicitly cast the ID entries to the SilcIDListData
5242 structure and get common data for the entries. In past, we had
5243 to first check what type of connection it is and then cast it to
5244 correct ID entry type. Now, we can directly cast the opaque
5245 pointer to the SilcIDListData (no matter what ID entry it actually
5246 is) and get the data needed.
5248 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5251 in some circumstances even if threre were timeout tasks, though not
5252 IO tasks, but tasks anyway. Now fixed.
5254 * Defined SilcServerConnection structure to hold connection specific
5255 stuff about directly connected servers and routers. The definition
5256 is currently in silcd/server_internal.h. I thought about having
5257 a bit more important role fro this struct but for now it is used
5258 only when connecting to other server (or router actually).
5260 * Added connecting retry support in server when connecting to
5261 router(s). The retry feature implement exponential backoff
5262 algorithm. Also, added SilcServerParams structure to hold default
5263 parameters for server. For now, it include these retry settings
5264 and are hard coded. After server is moded to be as Silc Server
5265 Library this structure will be more important.
5267 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Changed client librarys channel->clients table to SilcList and
5270 changed code accordingly.
5272 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Changed client's channel table to SilcList and changed code
5275 accordingly. Also changed SilcChannelClientEntry to include back-
5276 pointer to the channel so that client entry can use that structure
5277 as list as well and we have fast cross-reference to the channel.
5278 This change dramatically decreased the complexity of channel
5279 handling with client entry and vice versa (removed one extra
5280 loop when searching for channel entry from many functions).
5282 * Changed server->sim from table to SilcDList and changed code
5285 * NAMES command can now be used from user interface. It will show
5286 the user list on the channel, neatly.
5288 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5289 Code now saves realname of the user if it becomes available.
5291 * Renamed configure.in to configure.in.pre and made ./prepare
5292 script to automatically add correct version string to
5293 configure.in which it creates from configure.in.pre.
5295 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * NAMES command reply now shows users mode with the nickname when
5300 * Moved silc_client_ch[u]mode[_char] functions from
5301 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5302 place sucks, they are utility functions and should be in some
5305 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5307 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5310 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Added TRQ (efficient deque and list library) into lib/trq. This is
5315 a very good list library that is currently used in the SILC. Defined
5316 SilcList API over the library because I didn't like the API very
5317 much. See lib/trq/silclist.h for the API and examples of how to
5318 use the API. Fixed various places in the code to use the new
5319 SilcList API. The SilcList is meant for lists that has a structure
5320 already defined as a list. It is not suitable to add just some
5321 context to the list (in TRQ, the context is the list actually).
5323 So, I defined SilcDList that can be used for the purpose where
5324 predefined list structure does not exit. This can be used as
5325 such list. Now some context just can be added to the SilcDList.
5326 Currently this list is not used in the SILC just yet, though there
5327 are a lot places where this can replace dynamically allocated
5328 tables and I will fix these places, later, to use SilcDList.
5329 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5330 and use TRQ internally).
5332 Also fixed some annoying warning messages that the original TRQ
5333 code generated. Also minor changes to TRQ's Makefile.in.
5335 * Added support for querying by Client ID to both WHOIS and
5336 IDENTIFY commands into server, as required by the protocol.
5338 * Removed method function pointers from SilcBuffer structure. They
5339 weren't used to anything and just increased the context size for
5340 no good reason. This change also made silc_buffer_alloc and
5341 silc_buffer_free functions inline functions.
5343 * Disabled command flooding detection support until it's fixed so
5344 that it accepts commands in but does not execute them more than once
5347 * Added silc_net_localhost(), to return local hostname, into
5348 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5349 that must be initialized before calling silc_client_init.
5351 * Added new function: silc_server_send_notify_on_channels to send
5352 notify messages to all channels client has joined. It is assured
5353 that the message is sent only once per client.
5355 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5356 lib/silcutil/silcutil.[ch] as silc_format function. The new
5357 function is generic and is used by server as well, not only by
5358 the logging routines.
5360 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5361 the provided version string was not acceptable. Added new function:
5362 silc_ske_check_version into lib/silcske/silcske.h. The function
5363 must be implemented by the application (client or server) and it
5364 does not reside in the SKE library. The function checks the version
5365 string remote end sent.
5367 * Added back pointers (to opaque context and to SilcSocketConnection)
5368 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5370 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5371 duplicate packet context structure.
5373 * Changed `notify' client operation to send same arguments as client
5374 receives from server except for ID's. ID's are mapped to correct
5375 ID entry and that is returned. Also, if channel entry is not sent
5376 by server but the notify is for channel the channel entry is sent
5377 to application (otherwise application doesn't know that it is for
5378 channel (library gets it from packet's Destination ID)).
5380 * Added silc_client_remove_from_channels into client library to
5381 remove a client from all channels it has joined to. Used when
5382 received SIGNOFF notify from server. Added also new function
5383 silc_client_replace_from_channels to replace old ID entry with
5384 new ID entry on all channels. Used when received NICK_CHANGE
5387 * Fixed ID Cache list handling in silc_idlist_get_client in
5388 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5389 to get (or query) client by ID.
5391 * Updated TODO list.
5393 * Added connection authentication status message defined by the
5394 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5395 support for these into the code in client and server side.
5397 * Added generic function silc_client_send_command to send any command
5398 with variable argument list. Application should use this function
5399 to send commands if the command functions provided by the library
5400 does not suite for the application's user interface needs.
5402 * Added new `failure' client operation. Application is notified about
5403 received failure packet if client is executing a protocol. In this
5404 case the protocol's execution has failed.
5406 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5407 is required by the protocol.
5409 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5410 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5413 * Added status flag to SilcSKE object to indicate realtime status
5414 of the SKE protocol.
5416 * Application receives now exactly same command reply arguments as
5417 the library receives from server. However, if ID is received the
5418 corresponding ID entry is returned to the application (eg. Client
5419 ID is mapped to correct SilcClientEntry entry and that is returned).
5420 Changed command_reply client operation due to this change.
5422 * Changed all ID's in commands and in command replys as ID Payloads.
5423 Change affected both client and server side codes.
5425 All ID's sent in SILC network (with execption of ID's in SILC
5426 Packet header) are sent in ID Payload to support variable length
5429 * Server now notifies nick changes and notifies all clients on
5430 the channels about the new nickname (about the new Client ID,
5433 * Implemented CMODE command to change channel modes. Supports all
5434 channel modes defined by the protocol specs except ban and invite
5435 lists. (Also, private channel key mode is supported but support for
5436 setting private channel key in client is missing, thus, this mode
5437 has no effect on client side (except that server requires that the
5438 client uses private channel key and normal channel traffic does not
5441 Also, invite mode works per se, but INVITE command does not work
5442 yet correctly, so you can set channel as invite only channel but
5443 inviting clients to the channel does not work (it is yet to be
5444 thought what's the best way to do it).
5446 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5447 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5448 Implemented CUMODE command to change user's mode on the channel.
5449 Supports all modes defined by the protocol specs.
5451 * Added NAMES command reply to return users modes on the channel.
5453 * Removed unnecessary and slow ciphers from lib/silccrypt.
5455 * Set SO_KEEPALIVE option to connection sockets by default.
5457 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5459 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5460 redefined the Notify Payload into protocol specs.
5462 * Added silc_id_payload_parse_id to get ID directly from raw
5465 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5468 accept searching by Client ID as well.
5470 * Added support for LEAVE and SIGNOFF notify types in client library.
5472 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5473 to parse ID Payload from raw data.
5475 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Added flags parameter into silc_ske_assemble_security_properties
5478 function in lib/silcske/silcske.[ch].
5480 * Changed notify client operation to fit better for notify messages
5481 sent by server. The notify payload received from server is now
5482 passed to the application (after parsing it to SilcNotifyPayload).
5483 It is application's responsibility to retrieve the arguments
5484 from the payload and show the message the way it wants. The message
5485 sent by server is implementation specific.
5487 * Changed public keys to comply with the protocol specification.
5488 Old public keys are not supported anymore and are not compatible.
5490 * Removed nickname from Channel Payload as the latest draft removed
5491 it. The client must resolve the nickname from the NAMES command
5492 reply received when it joined the channel.
5494 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5496 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Fixed some errors in protocol specification drafts.
5500 * Created lib/silccore/silcnotify.c to implement Notify Payload
5501 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5502 generic payloads described by protocol specifications. The file
5503 includes implementations for ID Payload and Argument Payload.
5505 * Changed Command Payload implementation to use the new Argument
5506 Payload. Changed command_xxxx_payload to command_payload_xxxx
5507 to comply with SILC coding conventions.
5509 * Added suppport for Argument Payload handling in Notify Payload
5510 implementation as protocol requires it. Added the new support
5511 into server and client lib as well.
5513 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Added support for multiple nicknames on same channel. [n] is
5516 added locally to the nickname if there are more than one same
5517 nicknames on the channel.
5519 * Server now sends all nicknames that matched WHOIS request.
5520 Client also shows the list received from server.
5522 * Added TOPIC command to client side. User can now set and show
5523 current topic on channel.
5525 * Added MOTD command to client and server. Also, server sends the
5526 motd when client connects to the server.
5528 * Changed version strings to comply ISO 8601.
5530 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Fixed protocol error handling in client library. It should now
5533 cope even if the SKE fails for some reason.
5535 * Made new protocol specification drafts for submitting to IETF.
5537 * Implemented TOPIC command to server in silcd/command.c.
5539 * Added two new notify types into lib/silccore/silcnotify.h:
5540 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5541 notify nickname change and topic setting/change on a channel.
5543 * API change of command_reply operation in client library. The
5544 application gets now the status type received from server as well.
5546 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5550 * Cras fixed and optimized the packet handling even further and
5551 it should work now. Minor change to the prototype of function
5552 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5554 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Added new function into lib/silcutil/silcschedule.[ch]:
5557 silc_schedule_with_fd to select() a specified fd. The function
5558 returns after timeout expires or data arrives or goes. The
5559 function is used by packet routines to wait that all data is
5560 received from network.
5562 * Fixed data reading from network in lib/silccore/silcpacket.c.
5563 The code now assures that all data is read from the fd and then
5564 continues packet processing. This was a bug fix since the code
5565 used to drop some data in some circumstances.
5567 * Added new function into lib/silcclient/client.[ch]:
5568 silc_client_start_key_exchange to start key exchange after
5569 connection has been established to server. The code internally
5570 now uses this funtion but its main purpose was to provide it
5571 for applications that perform their own connecting. After
5572 application has created a connection it merely calls this
5573 function to start the key exchange between client and server.
5574 The library takes care of everything else after that.
5576 Updated also lib/silcclient/README to explain the usage of
5579 * Do not send to application information that connection has
5580 been established. Application gets notified it by connect
5583 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Applied cras's patch to add silc_schedule_one function. The
5586 function runs scheduler once and returns.
5588 * Fixed the scheduler after cras messed it up. The timeout
5589 handling works now as it's supposed to work.
5591 * Added into lib/silccore/ silcnotify.h to include notify
5592 message types support. Changed silc_server_send_notify*
5593 functions, in server.[ch], to support those new notify types.
5594 Added the support for the notify types into client library,
5595 as well. Added new notify client operation into ops.h in
5598 * Changed silc_server_packet_send_to_channel to send normal
5599 packets instead of just channel message packets. The function
5600 is now used to send the notify packets to channels. It is not
5601 used to send channel message packets anymore, as server never
5604 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5605 va_arg()s as it seems to require it nowadays. I guess, if SILC
5606 is compiled with older va_arg() the new code should work anyway.
5608 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Splitted core library. Core library (lib/silccore) includes
5611 now only SILC protocol specific core (and common) components.
5612 Created new utility library (lib/silcutil) that includes more
5613 generic purpose stuff. The stuff for util library was taken
5614 from the old core library. This was minor and easy split.
5616 * Created SILC Client Library (lib/silcclient) that includes
5617 implementation of the SILC client without user interface. This
5618 was major move from silc/ directory. The code has been changed
5619 so that it is transparent towards the user interface. The
5620 silc/ directory includes now the same user interface as before
5621 and it uses the new client library. Read lib/silcclient/README.
5622 Basicly, the client library performs everything else related
5623 to SILC except user interface handling. Also, configuration
5624 files are considered to be part of user interface and library
5625 does not handle them.
5627 This change also changed a lot of structures, function naming etc.
5628 Most important change was that SilcClientWindow object was
5629 renamed to SilcClientConnection in the client library. Created
5630 also new file lib/silcclient/ops.h. Also added new files
5631 silc/local_command.[ch] and silc/client_ops.[ch].
5633 All these changes were made to make it easier for user interface
5634 designers to create what ever user interface for the SILC client
5637 It is also expected that the server will be moved to lib
5638 directory as well and SILC Server Library will be created;
5639 sometimes in the future.
5641 * Removed Local commands from lib/silccore/silccommand.h as
5642 they are application specific and new client library does not
5643 handle any of those anymore.
5645 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5646 old client implementation in silc/.
5648 * Added support for callback functions in SILC_LOG_* macros.
5649 Application can now set its own callbacks that will be called
5650 instead of using the default functions that will always print
5651 the debug messages to stderr (or stdout). Also, debugging can
5652 now be disabled by setting silc_debug to FALSE and re-enabled by
5653 setting it to TRUE. Note, that logging will still work even
5654 if debugging is disabled.
5656 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5657 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5658 silc_log_reset_debug_callbacks.
5660 * To enable debugging in silc client one must give now -d
5661 option on command line.
5663 * Changed silc_schedule_init to automatically allocate task queues
5664 if they are not allocated before calling it.
5666 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Added GMP 3.1 into math library.
5670 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5673 a channel in SILC network. The packet is used by servers and
5674 routers to notify other routers that user has left a channel.
5675 This little feature was missing until now. Added the feature
5676 to protocol specification as well.
5678 Added functions: silc_server_send_remove_channel_user and
5679 silc_server_remove_channel_user into server.[ch].
5681 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5682 lib/silccore/silcpacket.h. However, they are not implemented
5685 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Fixed joining to a channel and sending channel messages
5688 between server and router. The channel message sending should
5689 now work inside a cell.
5691 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Fixed the private message sending between server and router.
5694 The private message sending should now work inside a cell.
5696 * Added silc_server_replace_id into server.[ch] to replace
5697 existing ID in the SILC network.
5699 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5700 and silc_idlist_replace_server_id into idlist.[ch] in server.
5702 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Fixed the server to server connections. Server can again now
5705 connect to router. Router to router connections probably does
5708 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Added dynamic protocol registering support. Now protocols can
5711 registered and unregistered on the fly. Patch by cras.
5713 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added lib/contrib directory to hold routines that some platforms
5716 don't have but are needed by SILC.
5718 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5719 into lin/contrib to provide getopt() and getopt_long() for
5720 those who don't have it.
5722 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Added AWAY command to client. When away message is set and
5725 client receives a private message packet the client automatically
5726 replies to the sender with the away message.
5728 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5729 bug seemed to be the cause of recent problems when compiling
5732 * Added version detection support to SKE protocol specification
5733 and added the new changes to the SKE implementation as well.
5734 There were other minor changes in the SKE protocol as well.
5736 Many changes in lib/silcske/silcske.[ch] and in
5737 lib/silcske/payload.[ch].
5739 * Added ^U functionality, clear input line. Patch from cras.
5741 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Mainly small bugfixes on core library. Fixed some debugging
5744 logging and buffer overflow in silclog.c.
5746 * Updated config.sub and config.guess on the distribution tree.
5748 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Added command lagging support in server. Client may execute
5751 commands now only once in two seconds.
5753 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Optimized packet reception. MAC computation and checking is now
5756 also more optimized. A lot previously duplicated code is now
5757 used as generic by both client and server.
5759 * Fixed key pair generation in clientutil.c
5761 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Added into lib/silccore/silcbufutil.[ch] new function;
5764 silc_buffer_realloc.
5766 * Moved generic packet sending/encryption functions to
5767 lib/silccore/silcpacket.[ch] from client and server. Some
5768 rewriting of the functions.
5770 * Moved all generic packet reception/decryption functions to
5771 lib/silccore/silcpacket.[ch] from client and server. The
5772 packet processing is now much cleaner in both client and server.
5773 These were major changes in both client and server.
5775 * Created many common functions in server to do packet sending.
5776 Previously code were duplicated a lot, this has been removed
5779 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Rewrote major parts of the ID cache system. Don't know
5782 whether it is better now or not but at least the API is more
5785 * Major rewrite on ID cache stuff on client because of the ID
5786 cache API changes. Added idlist.c to client.
5788 * Also major rewrite on ID cache stuff on server as well.
5789 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5790 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5791 in hand, instead they are all put into the ID cache system now.
5792 All server_idlist_* routines uses ID cache now instead of
5793 traversing its own lists (those lists does not exist anymore).
5794 SilcIDList though still exists. Also, SilcXXXEntry's are
5797 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Finally made the SKE implementation compliant to the protocol
5800 specification. All mp integers are now binary encoded as
5801 opposed being HEX encoded.
5803 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5806 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5807 functions: silc_[encode/decode]_pem. Also added function
5808 silc_encode_pem_file to PEM encode with newlines ('\n') for
5811 * SILC public keys are now encoded either PEM or binary. Same
5812 option is for private keys as well. By default private keys
5813 are binary encoded and public keys PEM encoded. Silly HEX
5814 encoding were removed.
5816 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5817 function to create fingerprints.
5819 * Fixed a bug in SHA1; does not change the original data anymore.
5821 * Partly implemented INFO command on client and server side.
5822 Fixed CLEAR command. Changes to SERVER command; show current
5823 server(s) when giving command without arguments. Added
5824 VERSION command to client.
5826 * Added check to server that unregistered connections cannot
5827 execute commands (unless it is specificly allowed).
5829 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Fixed screen refresh.
5833 * Fixed channel joining bug from client. On some circumstances
5834 client tried to join to a channel it had already joined.
5836 * Added public key verification process into client's protocol.c.
5837 The client now verifies the public key from user and saves
5838 it into ~./silc/serverkeys/ directory.
5840 Added into: clientutil.[ch]: silc_client_verify_server_key.
5842 * Changed SKE protocol's silc_ske_initiator_finish function
5843 to accept callback function that verifies the received public
5844 key. Removed old silc_ske_verify_public_key function.
5846 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5849 silc_pkcs_private_key[_data]_set.
5851 * Made the password and public authentication more cleaner in
5852 server's protocol.c.
5854 * Removed historic and obsolete protocol `channel_auth' from
5855 both client and server.
5857 * Removed wrong way of sending command status messages from
5858 server to client in server's command.c. The old way violated
5859 protocol specification.
5861 Changes to silccore/silccommand.[ch]: removed
5862 silc_command_encode_status_payload -> not needed anymore,
5863 changed silc_command_encode_payload_va to accept extra
5864 argument on variable argument list. The argument type must
5865 now be provided to the function. Also, added new function:
5866 silc_command_encode_reply_payload_va which is same as
5867 normal command_encode_payload_va except command status type
5868 is provided as extra argument.
5870 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Added ~./silc directory handling. The directory includes the
5873 public and private keys for the client.
5875 Added silc_client_check_silc_dir, silc_client_create_identifier
5876 and silc_client_load_keys.
5878 * Implemented SILC protocol compliant public key. Added public
5879 and private key saving to and loading from files.
5881 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5882 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5883 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5884 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5885 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5887 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5888 silc_pkcs_load_[public/private]_key.
5890 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added silc_server_get_route (route.[ch]) to get connection
5893 data for the fastest route for given ID.
5895 * Implemented INVITE command on client and server. The command
5896 were re-defined in the SILC Protocol Specification and the
5897 implementation now complies with the specification.
5899 * Implemented PING command on client and server.
5901 * Implemented NAMES command on client and server. The server side
5902 supports currently only normal server not router server yet.
5903 Some changes to NAMES definition in SILC protocol specification.
5905 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Implemented LEAVE command on client and server.
5909 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5910 again. This change was made to the protocol as well. Server
5911 should not violate the protocol specification anymore.
5913 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5916 was tested. SOCKS4 was not but should work anyway.
