+Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added silc_server_connection_auth_request to handle the
+ incoming CONNECTION_AUTH_REQUEST packet. Affected file is
+ silcd/packet_receive.[ch].
+
+ * Added silc_server_send_connection_auth_request into the
+ silcd/packet_send.c to send the connection auth request packet.
+
+ * Cleaned up the silcd/protocol.c a bit and fixed some memory
+ leaks.
+
+ * Fixed the public key authentication in responder side in the
+ server. The `auth_data' pointer includes the SilcPublicKey
+ not the path to the public key. Affected file silcd/protocol.c.
+
+ * Implemented the public key authentication in the initiator side
+ in the server. Affected file silcd/protocol.c.
+
+ * Removed the [RedirectClient] config section from the server
+ configuration. Is not needed and I don't want to implement it.
+
+Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Cleaned up the CMODE command in the server. It now works
+ correctly and supports all the modes defined in the protocol.
+ Affected file is silcd/command.c.
+
+ * Added `hmac_name' field to the SilcChannelEntry in the server
+ to hold the default HMAC of the channel. It can be set when
+ creating the channel (with JOIN command). Affected files
+ silcd/idlist.[ch].
+
+ * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
+ type to indicate the change of the current cipher and hmac
+ on the channel. Client can safely ignore the <cipher> argument
+ (if it chooses to do so) since the CHANNEL_KEY packet will
+ force the channel key change anyway. The <hmac> argument is
+ important since the client is responsible of setting the new
+ HMAC and the hmac key into use.
+
+ * Fixed the CMODE command in the client library as well.
+
+ * Tested CMODE command in router environment successfully.
+
+Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Show the version of the remote client (or server) when connecting
+ to the server. It is logged to the log file. Affected file
+ is silcd/protocol.c.
+
+ * Fixed the KILLED notify handling in the client library. The
+ client must be removed from all channels when receiving the
+ KILLED notify.
+
+ Also, do not remove the client entry when giving the KILL
+ command but when the KILLED notify is received.
+
+ * Removed silc_idlist_find_client_by_nickname from the server.
+ Not needed anymore. Affected files silcd/idlist.[ch].
+
+ * Implemented the CHANNEL_CHANGE notify type handling to the
+ server. Affected file silcd/server.c.
+
+ * Updated TODO.
+

+
+ * Added function silc_server_get_client_resolve to find the
+ client entry by ID from all ID lists and then resolve it
+ (using WHOIS) if it cannot be found. Affected file is
+ silcd/server.[ch].
+
+Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented the BAN command to the client library.
+
+ * The JOIN command in the server now checks the invite list
+ and the ban list.
+
+ * Changed the silc_command_reply_payload_encode_va and the
+ silc_command_payload_encode_va to support that if argument is
+ NULL it ignores and checks the next argument. Affected file
+ lib/silccore/silccommand.c.
+
+ * Added silc_server_send_notify_ban to send the BAN notify
+ type between routers.
+
+ * Chaned the silc_notify_payload_encode to support that if

+
+ * Tested ban lists in router environment successfully.
+
+Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

+ the new ban and invite lists.
+
+Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Redefined the INVITE command. The same command can be used to
+ invite individuals to the channel but also to manage the invite
+ list of the channel (to add to and remove from the invite list).
+ Updated the protocol specs.
+
+ * Added new command SILC_COMMAND_BAN that can be used to manage
+ the ban list of the channel. Updated the protocol specs.
+
+ * Removed the channel modes: the SILC_CMODE_BAN and the
+ SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
+ in the CMODE command. The equivalent features are now available
+ using INVITE and BAN commands. Updated the protocol specs.
+
+ * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
+ in the network about change in the current ban list. The notify
+ type is not used by the client.
+

+ support the invite lists.
+
+Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new function silc_string_regexify that converts string
+ including wildcard characters into regex string that can
+ be used by the GNU regex library. Added into the file
+ lib/silcutil/silcutil.[ch].
+

+
+ Added silc_string_regex_match to match two strings. It returns
+ TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
+
+Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Imported GNU regex to the soruce tree into lib/contrib.
+ Fixed some compiler warning from the regex.c.
+

+
+ * Fixed MOTD command in the server to work in router environment.
+
+ * Fixed the MOTD command in the client library to support
+ the server argument in the command.
+
+ * Added `nickname_len' argument to the silc_idlist_add_client
+ in the server, as the `nickname' argument may be binary data
+ (it may be hash).

+ the ID list.
+
+ * Implemented LIST command to the server. Affected file is
+ silcd/command.c.
+
+ * Implemented the LIST command to the client library and on the
+ user interface.
+
+ * Added [<user count>] argument to the LIST command reply.
+ With private channels the user count is not shown.
+
+ * Updated TODO and README.
+
+Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * The client entry's data.registered must be TRUE even with
+ global client entry on global client list. The data.registered
+ is used to check whether the client is anymore in the network,
+ for example with WHOWAS command so it must be valid.
+
+ * Fixed the WHOWAS command in the server. It now actually works
+ in router environment. Added function into silcd/command_reply.c
+ silc_server_command_reply_whowas_save.
+
+ * Added silc_idlist_purge function to the silcd/idlist.c
+ to periodically purge the ID Cache.
+
+ * Fixed INFO command in the server. It works now in router
+ environment. Added <server name> argument to the INFO command
+ reply. Updated the protocol specs.
+
+ * Fixed minor bug in silc_idcache_purge to not purge if the
+ expire value is zero.
+
+ * Fixed various bugs in WHOIS and IDENTIFY command handling as
+ they were buggy because of the WHOWAS information.
+
+ * Fixed local command MSG to handle the async resolving of
+ the remote client properly. It used to fail the first MSG.
+ Affected file silc/local_command.c.
+
+ * Added `data_len' field to SilcIDCache context.
+
+Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Update TODO. Todo in commands in the server.
+
+Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
+ used by routers as broadcast packet to inform other routers
+ about the changed user mode.
+
+ Implemented the notify handling in the server. Affected file is
+ silcd/packet_receive.c. Added the function
+ silc_server_send_notify_umode to the silcd/packet_send.[ch].
+
+ * Added new generic Channel Payload and deprecated the New Channel
+ Payload. The New Channel Payload is now the generic Channel
+ Payload.
+
+ * Added new argument `mode' to the silc_server_send_new_channel
+ as it is required in the Channel Payload now.
+
+ * Renamed the SilcChannelPayload to SilcChannelMessagePayload
+ and created a new and real SilChannelPayload to represent the
+ new generic Channel Payload. Implemented the encode/decode
+ for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
+
+ * Added silc_server_get_client_channel_list to return the list
+ of channels the client has joined for WHOIS command reply.
+ Affected file silcd/server.[ch].
+
+ * Implemented the channel list sending in the WHOIS command reply
+ in server and in the client.
+
+ Implemented the channel list displaying on the user interface
+ as well. Affected file silc/client_ops.c.
+
+ * Added silc_channel_payload_parse_list to parse list of Channel
+ Payloads. It returns SilcDList list of SilcChannelPayloads.
+ Client for example can use this function to parse the list of
+ channels it receives in the WHOIS command reply. The caller
+ must free the list by calling silc_channel_payload_list_free.
+ Affected files lib/silccore/silcchannel.[ch].
+
+Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added one new argument <user mode> to the WHOIS command reply
+ to return the mode of the user in SILC. Updated the protocol
+ specs.
+
+ Implemented it to the server and client.
+
+Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed the mode printing on the user interface on joining.
+ Affected file silc/client_ops.c.
+
+ * Implemented the UMODE command and user modes in general to the
+ client library and to the user interface.
+
+ * Implemented the UMODE command to the server.
+
+ * The server now sends UNKNOWN_COMMAND error status if client sends
+ unknown command. Affected file silcd/command.c.
+
+ * All server commands now handle the command identifier the right
+ way when sending the command reply to the client. The client can
+ use to identify the command replies with the identifier.
+
+Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added silc_server_get_client_route to resolve the route to
+ the client indicated by the client ID. Affected file is
+ silcd/server.[ch].
+
+ * Added silc_server_relay_packet as general function to relay
+ packet to arbitrary destination. This deprecates functions
+ like _send_private_message_key, _relay_notify etc. Affected
+ file is silcd/packet_send.[ch].
+
+ Removed silc_server_send_key_agreement,
+ silc_server_send_private_message_key and
+ silc_server_packet_relay_notify functions from the file
+ silcd/packet_send.[ch].
+
+ * Updated TODO.
+
+ * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
+ server. Affected file silcd/packet_receive.[ch].
+
+ * Implemented the KILL command to the client. Implemented the
+ SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
+ Affected files lib/silcclient/command[_reply].c and
+ lib/silcclient/client_notify.c. Implemented the KILL notify
+ printing in the user inteface.
+
+ * Fixed a lot silc_parse_nick memory leaks from the client
+ library in the file lib/silcclient/command.c.
+
+ * Changed the silc_server_send_notify_on_channels's `sender'
+ argument from SilcSocketConnection to SilcClientEntry to
+ check the sender as entry and not as connection object and not
+ to send to the client provided as argument. The affected file
+ is silcd/packet_send.[ch].
+
+ * The notify packets that are destined directly to the client used
+ to not to be processed by the server. Now changed that and the
+ server processes all notify packets. After relaying the packet
+ to the client the notify packet is processed in the server.
+
+ * The silc_server_free_client_data now checks whether there is
+ pending outgoing traffic for the client and purges the data to
+ the network before removing the client entry.
+
+Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
+ an client is killed from the SILC Network. Updated the protocol
+ specs accordingly.
+
+ Added new function silc_server_send_notify_killed to the
+ silcd/packet_send.[ch].
+
+ * Added function silc_server_packet_relay_notify to relay notify
+ packets that are destined directly to a client. In this case
+ the server does not process the notify packets but merely relays
+ it to the client. Affected file silcd/packet_send.[ch].
+
+ Added also silc_server_packet_process_relay_notify to check
+ whereto relay the notify. Affected file is
+ silcd/packet_receive.[ch].
+
+ * Implemented the KILL command to the server.
+
+ * Updated TODO.
+
+ * Added the backup schema desgined last fall to the protocol
+ specs for everyone to see. The specification is in the
+ *-spec-xx.txt draft and the packet type definitions for the
+ backup routers is in *-pp-xx.txt draft. Thusly, added also
+ new packet type SILC_PACKET_CELL_ROUTERS.
+
+ * A big security problem in the implementation discovered. The
+ signoff of an client did not cause new channel key generation
+ which it of course should've done. The channel keys must be
+ always re-generated when client leaves (or signoffs) the channel.
+ The silc_server_remove_from_channels funtion now handles
+ the channel key re-generation.
+
+ * Added `sender' argument to the silc_server_send_notify_on_channels
+ to not to send the client provided as argument. Affected file
+ silcd/packet_send.[ch].
+
+Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented OPER and SILCOPER commands into the server and
+ the client library.
+
+ * Added silc_auth_verify and silc_auth_verify_data to verify
+ the authentication directly from the authentication payload.
+ It supports verifying both passphrase and public key based
+ authentication. Affected file lib/silccore/silcauth.[ch].
+
+ * Added `hash' field to the SilcIDListData structure. It is the
+ hash negotiated in the SKE protocol. Affected file is
+ silcd/idlist.[ch].
+
+ * Slight redesigning of the SilcAuthPayload handling routines.
+ Do not send SilcPKCS but SilcPublicKey as argument.
+
+ * Implemented the public key authentication support to the
+ serverconfig. The public key is loaded from the provided path
+ and saved as authentication data to void * pointer. Thus,
+ changed the unsigned char *auth_data to void *auth_data;
+
+ * Fixed SHUTDOWN command to send the reply before the server
+ is shutdown. :) Affected file silcd/command.c.
+
+ * Fixed fatal bug in CONNECT command. The hostname was invalid
+ memory and server crashed. Affected file silcd/command.c.
+
+ * Fixed fatal bug in CLOSE command. The server_entry became
+ invalid but was referenced later in the command. Affected file
+ silcd/command.c.
+
+Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed fatal bug in failure packet handling. Server ignored
+ the failure and thus crashed when it came.
+
+ * Updated TODO.
+
Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new SILC_CF_LAG_STRICT command flag that strictly forces
