RCON lacked encryption, added AES-CTR encryption on RCON frames. Slightly adjusted protocol to take this into account (sending nonces, encrypted data itself, etc).
This code was actually part of the LiveAPI system, but there were many opportunities to make this particular code modular, so it has been decoupled and moved to Tier2. The LiveAPI system will soon use this class instead. The implementation has also been improved by adding dedicated routines for updating socket parameters, disconnecting/reconnecting and destroying sockets.
This commit also removes legacy workaround code in UtlVector which was used for before we had early enough access to the game's memalloc singleton. This code was no longer used.
This commit also implements the CUtlStringList class, which is now used for the new websocket class to split each socket connection up by a comma delimiter.
The implementation in the engine always took/returned signed 64bit size types, but I made a mistake when reversing the virtual function table. All types have been changed to what they should be (mostly signed 64bit, very few unsigned), and usage in-SDK has been adjusted accordingly.
CConnectedNetConsoleData was allocated and deallocated manually, but std::vector is able to do it on its own. The vector type has been swapped out with CUtlVector as this removed the need of having to cast size types to a 32bit int to make it more compatible with the other sdk/engine types without throwing compiler warnings.
Previously, it was all controlled from the global init (applied to all projects), but some projects need different options. With these changes, you can disable the common options applied in the 'add_module' macro, and set your own if desired.
Since this file no longer gets build along with the DLL project, but as a static lib instead, the 'DEDICATED' define no longer worked, and therefore this became broken after the CMake port. The 'CURLHandleError' helper function now takes a bool determining whether or not to log the error, and the caller disables it for dedicated (dedicated should only log the error once, this happens from within the caller class).
Treat them as errors globally. Most of the time a warning is a bug, or problem in code that could be solved in a different (better) manner. Thirdparty code have this disabled. The warnings as errors option can be globally disabled through the CMake GUI, but this is not recommended.
Use the 'add_module' macro to add modules without creating duplicate code. This macro also takes a reuse PCH as parameter, so modules that need a precompiled header, could reuse those from different targets that compile them. This commit also restructures the group order of the generated solution files for easier code navigation.
* All libraries have been isolated from each other, and build into separate artifacts.
* Project has been restructured to support isolating libraries.
* CCrashHandler now calls a callback on crash (setup from core/dllmain.cpp, this can be setup in any way for any project. This callback is getting called when the apllication crashes. Useful for flushing buffers before closing handles to logging files for example).
* Tier0 'CoreMsgV' function now calls a callback sink, which could be set by the user (currently setup to the SDK's internal logger in core/dllmain.cpp).
TODO:
* Add a batch file to autogenerate all projects.
* Add support for dedicated server.
* Add support for client dll.
Bugs:
* Game crashes on the title screen after the UI script compiler has finished (root cause unknown).
* Curl error messages are getting logged twice for the dedicated server due to the removal of all "DEDICATED" preprocessor directives to support isolating projects. This has to be fixed properly!
* Decoding and encoding is done into a single buffer, from raw buffers to avoid extraneous copies.
* Added base class holding all core logic for encoding, decoding, receiving and processing of the RCON protocol. This code was initially identical between all implementations of RCON, deduplicating this avoids bugs.
* Added more sophisticated error handling, stop right away when decoding for example fails.
* Added ability to have more than one active authenticated net console on the server. Controlled by cvar 'sv_rcon_maxconnections' (default 1).
* Max packet size for accepted, but not authenticated sockets is now controled by cvar 'sv_rcon_maxpacketsize' (default 1024).
* Fixed 'connect' socket bug preventing connection to IPv4 addresses, by making the method used by the listen socket and connect socket configurator shared (dual stack was disabled on connect, but not on listen).
* Removed extraneous member from the 'CSocketCreator' class, this member was a copy of the 'netadr_t' input, but nothing ever was done with it.
* Put initializer values inside brackets.
* Put logical AND conditions within parentheses.
* Put assignments within conditional statements within parentheses.
* Mark unused variables as such to suppress compiler warnings.
* Fix vftable shadow warnings caused by ConVar::CreateInternal (does not implement, only interface. Renamed to yield desired behavior).
* Fix 'never' initialized class members for 'CCVarIteratorInternal'.
* Return values in interface vftables that cannot be pure virtual.
* Removed duplicate json parsing that was part of a PR that required a small refactor.
* Only check if response buffer is empty when we are going to parse the error message (this helps finding bugs in master server, since failure to parse has an exception handler).
* Log private server token and error messages to dedicated server console.
* Use game's CNetAdr RCON and socket creator.
* Add support for constructing host from [ip]:port format in the netconsole client.
* Pass 'netadr_t' parameter by reference to 'CSocketCreator::OnSocketAccepted'.
* Promoted size types in CUtlBuffer to int64.
* Fixed bug where CUtlBuffer::GetPtr returns a 64bit pointer that was promoted from a 32bit integral type.
* Use int64/size_t for anything strlen, pointer subtraction, etc..
* Removed invalid structure alignment declarations.
* 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.
