This member was in the class when RCON was added to the r5sdk, but it was never utilized. Now, each netconsole can toggle whether they are input only or not, the server only sends logs to netconsoles that are not input only. This patch also contains a fix in which the listen server sends logs to the client of its own process, causing an infinite recursive call to DevMsg.
* Prevent attacker from being able to abuse and overflow the banned list vector.
* Improved IPv6 comparison performance.
* Change size fields of payload frame from unsigned to signed.
* Close all accepted sockets on RCON server shutdown.
* Used 'htonl'/'ntohl' for constructing the length prefix.
* Used static socket/address members instead of pointers.
* Used const qualifier where possible.
* Changed length prefix field type to 'u_long'.
* Removed extraneous include.
* Properly escaped percentage characters on the RCON game client for the ImGui console.
Addressed:
* 'Expression: vector subscript out of range' (we only ever ensured capacity upon construction).
* Compiler error as AssertMsg1 is unimplemented, used Assert instead.
* Implemented robust length-prefix framing logic for non-blocking sockets (previously used character sequences to determine length, but you cannot use character sequences on protocol buffers as its binary data. This logic should fix all problems regarding some commands not getting networked properly to the server and stuff not getting printed on the client).
* Increased buffer size to std::vector::max_size when netconsole is authenticated (MAX_NETCONSOLE_INPUT_LEN still remains enforced on accepted but not authenticated connections to prevent attackers from crashing the server).
* Process max 1024 bytes each recv buffer iteration.
* Additional optimizations and cleanup.
** SERVER **
* Close redundant connections if max sockets have been reached.
* Ban if client keeps spamming without authing first (ignoring message).
* Check for whitelisted address before issuing bans (whitelisted address in ConVar 'sv_rcon_whitelist_address' will never get banned or get its connection terminated.
* Transmit SQVM and DevMsg logs over the wire to the net console.
** NETCON **
* IPv6 support.
* Close connection properly after FIN request.
* Prompt user to reconnect after connection has been terminated instead of closing the application.
* Add proper quit command.
** SDKLAUNCHER **
* Rename to 'launcher.exe' to describe its purpose better. Our logo gets printed nice and large on the console during startup.
** SDK **
* Cleanup.
* Fully rewritten protocol agnostic CNetAdr class
* Fully rebuilded legacy CNetAdr class
* Fully rebuilded dual-stack CSocketCreator class
* New project "netconsole" added (lightweight netconsole for RCON)
RCON is still work in progress
