+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.
+
+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.

- * 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.
