+
+Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Do not ask whether user wants to use the negotiated private key
+ for private messages, just use it. Affected file is
+ silc/local_command.c.
+
+ * Added `send_enc_key' and `enc_key_len' fields to the
+ SilcIDListData structure since they are needed in the re-key
+ phase. Affected file is silcd/idlist.[ch].
+
+ * Implemented the simple re-key protocol into the server.
+ Affected files silcd/server.c and silcd/protocol.[ch]. The
+ re-key will be performed once in an hour, by default.

+
+ * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
+ int64 of at least the xintXX size. If void * is less that 4
+ bytes uint32 * will be used. Defined bool as boolean.
+
+ * Changed _ALL_ unsigned long and unsigned int to uint32,
+ unsgined short to uint16 in the source tree.
+
+ * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
+ not handle clients that has entry->data.registered == FALSE.
+ They are not in the network anymore. Affected file is
+ silcd/server.c.
+
+Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented the sending of the SERVER_SIGNOFF notify in the
+ server. Affected file is silcd/server.c.
+
+ * Added silc_server_send_notify_args into silcd/packet_send.[ch].
+ Added also silc_notify_payload_encode_args into the
+ lib/silccore/silcnotify.[ch].
+
+ * Implemented ther SERVER_SIGNOFF notify handling in the server.
+ Affected file silcd/packet_receive.c.
+
+ * Implemented the SERVER_SIGNOFF notify handling in the client
+ library. Affected file lib/silcclient/client_notify.c. Also,
+ implemnted the printing of the SERVER_SIGNOFF info to the
+ application. Affected file silc/client_ops.c.
+
+ * The silc_idlist_del_server now returns TRUE or FALSE to indicate
+ if the deleting was successful. Affected file silcd/idlist.[ch].
+
+ * Added support for public key authentication in the connection
+ authentication protocol in the client library. Affected file
+ lib/silcclient/protocol.c.
+
+ * Changed the server's silc_idlist_get_clients_by_* interface
+ to support already allocated array so that new entries may be
+ added to pre-allocated array. Affected file silcd/idlist.[ch].
+ This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
+ and command replies.
+
+ * All command reply functions in the server now calls the
+ pending command callback even if error occured. This way the
+ error will be delivered to the client as well. Affected files
+ silcd/command.c and silcd/command_reply.c.
+
+ * Fixed INFO command to return local server's info if no server
+ was provided. Affected file lib/silcclient/command.c.
+
+ * Removed RESTART command for good. Updated the code and the
+ protocol specs.
+
+ * Rewrote parts of the task system. It is a bit simpler now.
+ Removed unsued task priorities. The affected files are
+ lib/silcutil/silctask.[ch].
+
+Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Moved the USERS printing from the library to the application.
+ Affected files lib/silcclient/command.c and silc/client_ops.c.
+
+Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Updated TODO.
+
+ * Added channel key re-key support. The re-key is perfomed
+ only by the router and is done once in an hour. Added `rekey'
+ field to the SilcChannelEntry in the server. Affected files
+ silcd/server.c and silcd/idlist.h.
+
+ * Added silc_task_unregister_by_context into the file

+
+Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added SILC_UMODE_GONE mode to indicate when the client is not
+ present in the SILC network. Added also support to the local
+ command AWAY that will set this mode. Added support of showing
+ "xxx is gone" in WHOIS command. The USERS command shows the
+ gone status as well.
+
+ * Fixed setting server and router operator privileges in the
+ server's UMODE command. Affected file silcd/command.c.
+
+ * Merged the SKE KE1 and KE2 payloads into one payload. The
+ new KE payload is equivalent to the old KE2 payload.
+
+ Cleaned up the SKE Start Payload parsing. It now uses the
+ simple buffer unformatting to do the parsing. A lot faster
+ now.
+
+ Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
+ to the SKE that is used to indicate whether both of the SKE
+ parties should perform authentication. By default only the
+ responder performs authentication. By setting this flag also
+ the initiator must do authentication. By default it is unset
+ since in normal SKE case, client to server connection, only
+ the responder should do authentication. When doing SKE between
+ two clients both should perform authentication. Updated the
+ code and the protocol specs.
+
+ * A little fix to IDENTIFY command in the server. Search the
+ client first by hash not nickname. Affected file is
+ silcd/command.c.
+
+ * Fixed the silc_client_close_connection to support closing
+ the client to client connections wihtout deleting too much
+ data. Affected file lib/silcclient/client.c.
+
+ * Fixed a fatal bug in server and client; if KE1 or KE2 packets
+ are received if protocol used to be active but is not anymore
+ the application would crash due to NULL pointer dereference.
+ Affected files silcd/server.c and lib/silcclient/client.c.
+
+ * Added `hash' field to the SilcClientConnection to include
+ the hash function negotiated in the SKE protocol.
+
+ * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
+ to set the channel founder authentication data. A client can
+ claim the founder rights later by providing the authentication
+ data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
+ This way the channel founder can regain the channel founder
+ privileges even it is left the channel. This works only on
+ local server and the client must be connected to the same
+ server to be able to regain the founder rights. Updated the
+ protocol specs accordingly.
+
+ Added support to the CMODE command in the client to set the
+ founder auth data. Read the README to see how to set it.
+
+ Added support to the CUMODE command to claim the founder
+ rights. Read the README to see how to do it.
+
+ Added support for the founder authentication to the Channel
+ Entry in the server. Affected file silcd/idlist.h.
+
+ Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
+ server's CMODE command. Affected file silcd/command.c.
+
+ * Added the following new functions into lib/silccore/silcauth.[ch]:
+ silc_auth_get_method and silc_auth_get_data.
+
+ * The server now saves the remote hosts public key to the
+ SilcIDListData pointer. Affected file silcd/protocol.c.
+
+ * The normal server now does not remove the channel entry from
+ the cache if the founder authentication data is set. It used
+ to remove it if the founder was the last one on the channel on
+ the server and left the channel. The auth data is saved and
+ if the channel is re-joined later the old entry is used with
+ the old auth data. Affected files silcd/command_reply.c and
+ silcd/server.c.
+
+ * Removed the `pkcs' field from the SilcIDListData structure
+ in the server; it is not used. Affected file silcd/idlist.h.
+
+Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed packet processing on slow links. Partial packets were
+ never re-processed because the incoming data buffer was cleared
+ by the application. Application must not directly clear the
+ sock->inbuf, the packet processing routines handle it. Fixed
+ this in client library and in server.
+
+Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed the WHOIS and IDENTIFY send reply function to really
+ check whether to send list or just one entry. Affected file
+ silcd/command.c.
+
+ * Cleaned up the LEAVE command's channel key distribution. The
+ affected file silcd/command.c.
+
+ * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
+ can enforce the channel mode as well. In that case the ID
+ includes the ID of the server. The code now enforces the
+ mode change if the router have different mode than the server.
+
+ * The notify client operation with CMODE_CHANGE notify can now
+ return NULL client_entry pointer if the CMODE was not changed
+ by client. Application must check for this.
+
+ * Added <Server ID> argument to INFO command to support server
+ info fetching by Server ID.
+
+ * Added silc_server_announce_get_channel_users to get assembled
+ packets of channel users of the specified channel. Affected
+ file silcd/server.[ch].
+
+ * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
+ was freed underneath the ID Cache.
+
+ * Re-announce clients when the server received CHANNEL_CHANGE
+ notify from the router. Affected file silcd/packet_send.c.
+
+Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
+ crashed since it did not handle the fact that there is no cipher
+ called "3" and didn't check the error condition. Now fixed.
+
+ * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
+ flag. It can be used to send message requests.
+
+Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented the RESTART command in the client.
+
+ * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
+ notice type messages. Added notice printing to the user
+ interface.
+
+ * The channel keys are not re-generated if the channel's mode
+ is PRIVKEY, ie private key on the channel exists. Affected
+ files silcd/server.c and silcd/command.c.
+
+ * Fixed a little bug in channel message delivery when channel
+ private keys are set in the server. Affected file is
+ silcd/packet_send.c.
+
+ * Changed the setting on channel->on_channel = TRUE from the
+ silc_client_save_channel_key to the JOIN command reply. The
+ key payload is not received if the private channel key is set.
+ Affected file lib/silcclient/command_reply.c and the
+ lib/silcclient/client_channel.c.
+
+ * When the CMODE_CHANGE notify is sent and the channel private
+ key mode is removed the channel key must be re-generated in
+ other cells as well. Added this support for the router in the
+ silcd/packet_receive.c.
+
+ * Added new local command NOTICE to send notice message on
+ channel. Affected file silc/local_command.[ch].
+
+Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new local command ME to the client. It is used to send
+ message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
+ some action. Affected file silc/local_command.[ch].
+
+ * Changed channel_message and private_message client operations
+ to deliver the message flags to the application. Added also
+ the `flags' arguments to the silc_client_send_channel_message
+ and silc_client_send_private_message functions. Affected file
+ silcapi.h.
+
+Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Redefined the Private Message Payload to support private message
+ keys and to support the new private message flags. Updated
+ the protocol specs. Flags makes it possible to have for example
+ CTCP style messages.
+
+ * Added new type SilcPrivateMessagePayload and defined an API
+ for it in the lib/silcclient/silcprivate.[ch].
+
+ * Tested private message private keys successfully. Tested the
+ private message key set, unset and list commands with the new
+ KEY command.
+
+ * Redefined the Channel Message Payload to include the channel
+ message flags (equal with private message flags) to support
+ for example CTCP style messages.
+
+ * Defined some of the message (for channel and private message)
+ flags. Updated the protocol specs and added the flags to the
+ lib/silccore/silcchannel.h. The type is SilcMessageFlags.
+
+Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added SilcKeyAgreementStatus type to the key agreement routines
+ to indicate the current status and error if one occured.
+ The status types are defined in the lib/silcclient/silcapi.h.
+
+ * Added new local command KEY that is used to set and unset private
+ keys for channels, set and unset private keys for private messages
+ with remote clients and to send key agreement requests and
+ negotiate the key agreement protocol with remote client. The
+ key agreement is supported only to negotiate private message keys,
+ it currently cannot be used to negotiate private keys for channels,
+ as it is not convenient for that purpose.
+
+ * Fixed a minor pending callback setting bug in the function
+ silc_client_get_client_by_id_resolve, now the function works.
+ Affected file lib/silcclient/idlist.c.
+
+ * Added function silc_net_get_local_port to get local bound
+ port by socket. Added to lib/silcutil/silcnet.[ch].
+
+ * Added `sockets' and `sockets_count' fields to the SilcClient
+ object. They hold the sockets of the listenning sockets in
+ the client. Listenning sockets may be for example the key
+ agreement server. Affected file lib/silcclient/client.[ch].
+ Added functions the silc_client_add_socket and the
+ silc_client_del_socket. They are exported to the application
+ as well.
+
+ * Added ~./silc/clientkeys to support other client's public keys.
+
+ * Renamed verify_server_key client operation to verify_public_key
+ and added one argument to indicate the type of the connection
+ (server, client etc.).
+
+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.
+
+Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added silc_server_send_notify_invite to send the INVITE
+ notify between routers.
+
+ * Implemented the INVITE command correctly to the server.
+
+ * Implemented the INVITE notify type handling in the server.
+
+ * Implemented the INVITE command to the client library and on the
+ user interface.
+
+Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * 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
+ argument is NULL it ignores and checks the next argument.
+ Affected file lib/silccore/silcnotify.c.
+
+ * Tested ban lists in router environment successfully.
+
+Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented BAN command to the server, in silcd/command.[ch].
+
+ * Removed the BAN and INVITE_LIST modes from the CMODE command
+ in the server code.
+
+ * Added function silc_string_match to regex match two strings.
+ Affected files lib/silcutil/silcutil.[ch].
+
+Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Redefined parts of the SilcChannelEntry in the server to support
+ 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.
+
+ * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
+ 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_combine to combine to regex strings
+ into one so that they can be used as one regex string 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].

+
+ * 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).
+
+ * Added silc_idlist_get_channels to return all channels from
+ 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>

+
+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.

+ 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].

+ * 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
+ that the command may be executed only once in (about) 2 seconds.
+ The old SILC_CF_LAG flag is same but allows command bursts up
+ to five before limiting.
+
+ Added the support for CF_LAG and CF_LAG_STRICT flags to the
+ server code. Various commands now includes the CF_LAG_STRICT
+ flag to disallow any kind of miss-use of the command.
+
+ * Fixed the silc_buffer_unformat to not to allocate any data
+ if the length of the data is zero. It used to allocate the
+ length + 1. Affected file lib/silcutil/silcbuffmt.c.
+
+Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Changed the format of AdminConnection configuration section
+ in the server. Added username of the admin to the format.
+ Affected files silcd/serverconfig.[ch].
+
+ Added silc_server_config_find_admin into silcd/serverconfig.[ch]
+ to return admin configuration data by host, username and/or
+ nickname.
+
+Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented WHOWAS command to the server. Added the functions:
+
+ silc_server_command_whowas_parse,
+ silc_server_command_whowas_send_reply,
+ silc_server_command_whowas_from_client and
+ silc_server_command_whowas_from_server
+
+ * Added <Client ID> argument to the WHOWAS command reply. Updated
+ the protocol specs accordingly.
+
+ * Implemented WHOWAS command and command_reply to the client
+ library.
+
+ Implemented the WHOWAS printing on the user interface.
+
+Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new argument to the WHOWAS command reply, the real name.
+ It is an optional argument. Updated the protocol specs.
+
+ * Added SilcIDCacheDestructor callback that is registered when
+ the SilcIDCache is allocated. The callback is called when
+ an cache entry in the ID Cache expires, or is purged from the
+ cache. Added into lib/silccore/idcache.[ch].
+
+ Added silc_idlist_client_destructor to the silcd/idlist.[ch]
+ to destruct the client entries when the cache entry expires.
+ Other ID Cache's in server and in the client library ignores
+ the destructor.
+
+ * If the ID Cache entry's `expire' field is zero then the entry
+ never expires. Added boolean `expire' argument to the
+ silc_idcache_add function in the lib/silccore/idcache.[ch].
+ If it is TRUE the default expiry value is used.
+
+ * Added silc_server_free_client_data_timeout that is registered
+ when client disconnects. By default for 5 minutes we preserve
+ the client entry for history - for WHOWAS command.
+
+Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added support to the server to enforce that commands are not
+ executed more than once in 2 seconds. If server receives
+ commands from client more frequently, timeout is registered
+ to process the commands. Affected file silcd/command.c.
+ Added new function silc_server_command_process_timeout.
+
+ * Changed NICK_NOTIFY handling in client library to check that
+ if the client's nickname was changed, so there is no need to
+ resolve anything from the server.
+
+ * Removed error printing from the WHOIS and IDENTIFY commands.
+ If error occurs then it is ignored silently in the client library.
+ The application, however, may map the received error to
+ human readable error string. The application currently maps
+ the NO_SUCH_NICKNAME error to string.
+
+ * Made the command status message public to the application. Moved
+ them from lib/silcclient/command_reply.c to
+ lib/silcclient/command_reply.h. The application can map the
+ received command status to the string with the
+ silc_client_command_status_message function.
+
+ * Added check to the server to check that client's ID is same
+ as the Source ID in the packet the client sent. They must
+ match.
+
+Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added dist-bzip hook to the Makefile.am to make bzip2
+ compressed distributions.
+
Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Server now enforces the maximum length for the nickname and
