+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].
+
+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.
+
+Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * 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).
+
+ * 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>
+
+ * 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 fromthe 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
+ the channel as protocol specification dictates. 128 bytes for
+ nickname and 256 bytes for channel name.
+
+ * Moved the WHOIS printing to the application. The client libary
+ does not print out the WHOIS information anymore, the application
+ must do it. Renamed silc_client_command_reply_whois_print to
+ the silc_client_command_reply_whois_save.
+
+ The client's idle time is also sent to the application now, and
+ the idle is shown on screen.
+
+ * Added silc_client_command_reply_identify_save to save the
+ received IDENTIFY entries.
+
+ * Do not check for channel private keys in message sending and
+ reception if the channel does not have the PRIVKEY mode set.
+ Affected file lib/silclient/client_channel.c.
+
+Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
+ just surfaced after chaning the JOIN procedure.
+
+Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added silc_client_get_clients_by_list to get client entries
+ from Client ID list, that is returned for example by JOIN
+ and USERS command replies. The application should use this
+ function for example when JOIN command reply is received to
+ resolve the clients already on the channel (library does not
+ do that anymore as USERS command reply is not used in the JOIN
+ procedure anymore). Affected files lib/silcclient/silcapi.h and
+ lib/silcclient/idlist.c.
+
+ * JOIN command reply and USERS command reply returns now SilcBuffer
+ pointers instead of unsigned char pointers when returning
+ the client list and mode list.
+
+ * Added <Client ID> argument to the JOIN command reply, mainly
+ for the server to identify for which client the command was
+ originally sent. Updated protocol specs accordingly.
+
+ * Added SilcDlist private_key pointer to the SilcChannelEntry
+ in the client to support the channel private keys. Affected
+ file is lib/silcclient/idlist.h.
+
+ * Added SilcChannelPrivateKey argument to the function
+ silc_client_send_channel_message so that application can choose
+ to use specific private ke if it wants to. If it is not provided,
+ the normal channel key is used, unless private keys are set.
+ In this case the first (key that was added first) is used
+ as the encryption key.
+
+ * Implemented the support for channel private key handling.
+ Implemented the following functions:
+
+ silc_client_add_channel_private_key,
+ silc_client_del_channel_private_keys,
+ silc_client_del_channel_private_key,
+ silc_client_list_channel_private_keys and
+ silc_client_free_channel_private_keys
+
+ Affected file lib/silcclient/client_channel.c.
+
+ * Added the support for the private keys in the channel message
+ sending and encryption and in the message reception and
+ decryption. Affected funtions are
+ silc_client_send_channel_message and silc_client_channel_message.
+
+Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added SKE's key verify callback to the client library's
+ KE protocol context. Affected files lib/silcclient/protocol.[ch].
+
+ * Removed the statement that server (or router) must send USERS
+ command reply when joining to the channel so that the client
+ knows who are on the channel. Instead, the client list and
+ client's mode list is now sent in the JOIN command reply to the
+ client who joined channel. This is better solution.
+
+ * Added function silc_server_get_users_on_channel and function
+ silc_server_save_users_on_channel to the silcd/server.[ch].
+
+ * Removed function silc_server_command_send_users from the
+ silcd/command.c.
+
+ * Do not show topic on the client library anymore. The topic is
+ sent in the command reply notify to the application and the
+ application must show the topic now.
+
+Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added client searching by nickname hash into the IDENTIFY and
+ WHOIS commands in the server as they were clearly missing from
+ them. Affected file is silcd/command.c.
+
+ * Fixed a bug in private message receiving in the client library.
+ The remote ID was freed and it wasn't supposed, now it is
+ duplicated.
+
Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
- * Minor fix t the channel payload; allocate the data area, as it
+ * Minor fix to the channel payload; allocate the data area, as it
needs to be of specific length.
* If the key agreement port is zero then the operating
system will define the bound port. Affected files are
lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
+ * Added new function silc_channel_payload_decrypt into the file
+ lib/silccore/silcchannel.[ch].
+
+ * Moved the channel message etc, check from silc_packet_decrypt
+ to applications. The library calls now a generic
+ SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
+ when the packet is either normal or special. This was done to
+ allow more wide range of checking that was not allowed when
+ the code was in library. Now applications can do virtually any
+ checks to the packet and return to the library the decision how
+ the packet should be processed. Affected files are
+ lib/silccore/silcpacket.[ch].
+
+ Added silc_server_packet_decrypt_check to the server and
+ silc_client_packet_decrypt_check to the client library.
+
+ * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
+ to send with specified source and destination information.
+
+ * Channel message delivery between routers was broken after the
+ channel key distribution was fixed earlier. The channel key
+ was used be to distributed to other routers as well which is not
+ allowed by the protocol. Now this is fixed and channel keys
+ really are cell specific and the channel message delivery between
+ routers comply with the protocol specification.
+
+ * Fixed various commands in server to check also the global list
+ for the channel entry and not just the local list. The affected
+ file silcd/command.c.
+
Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added assert()s to buffer formatting and unformatting routines
* Added Hmac field to the Channel Message Payload. The integrity
of plaintext channel messages are now protected by computing
MAC of the message and attaching the MAC to the payload. The
- MAC is not encrypted. Now, it is clear that this causes some
+ MAC is encrypted. Now, it is clear that this causes some
overhead to the size of the packet but rationale for this is that
now the receiver can verify whether the channel message decrypted
correctly and also when private keys are set for the channel the
lib/silccore/silcchannel.[ch]. The encode function now also
encrypts the packet and parse function decrypts it.
- * Channel message delivery between routers was broken after the
- channel key distribution was fixed earlier. The channel key
- was used be to distributed to other routers as well which is not
- allowed by the protocol. Now this is fixed and channel keys
- really are cell specific and the channel message delivery between
- routers comply with the protocol specification.
