Possible crasher is to send a stringcmd >= 512 in size with funny UTF8 characters and have CUtlBuffer::ParseToken() read past it. Apparently seems to be mostly a problem on 32bit? I was unable to initiate a crash, though one string caused interesting behavior before, and there was one report of the dedicated server being 'crashed' with this. There is no reason to tokenize it up to 512 bytes if the game is only ever going to allow 128, so clamp it to 129 and if the user exceeds it then they still get the message and we just jettison it.
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.
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.
The 'engine_cl' library defines 'CLIENT_DLL', which prunes server specific code. This is used for the 'client.dll' project. Also fixed a compile error in 'CClient::VActivatePlayer', as it used a server only cvar. Ideally, this entire file gets ifdef'd out for engine_cl, currently it doesn't matter as nothing gets compiled in.
CClient array is part of the CPlayer class. The array has been added, filling up most of the 'unknown' gap. Vtable override functions have been added as the array is static, and therefore requires an implementation of the vtable, these are just stubs however, since the vtable pointer points to the implementation in the engine.
Find regex pattern:
inline auto ([a-zA-Z0-9_]+) = ([a-zA-Z0-9_]+)\.RCast<([a-zA-Z0-9_:<>*]+) *\(\*\)\(([^)]*)\)>\(\);
Replace regex pattern:
inline $3(*$1)($4);
This commit also removes the unnecessary initialization (which was required to type the auto variables),
and therefore removed 6kb of unnecessary dynamic initialization code.
Global 'direct' usage of 'MemAllocSingleton()' has been jettisoned. Where possible, smart pointers were used instead. During the refactor, the following bugs were addressed and fixed:
- The virtual destructor of 'CCVarIteratorInternal' was NOT called on destruction.
- Class function 'KeyValues::MakeCopy' did NOT calculate the buffer size of the wide string correctly, the original calculation was 'len+1*sizeof(wchar_t)', but should've been '(len+1)*sizeof(wchar_t)'.
Some other code changes include:
- Tier0 include 'memstd.h' has been moved above all thirdparty includes, to make sure the memalloc functions get shadowed with ours in third party libraries as well.
- RPak file paths string literals are now defines.
- 'DestroyOverlay' has been refactored to match the assembly of the game.
This fixes a crash/exception that would occur when getting disconnected from your own listenserver due to the playlists reload task dispatch. Moving this to client only code, in the disconnect routine (post disconnect) fixes this problem.
Ported the logic from the more recent builds into the SDK rebuild. Note that this isn't all that has changed in the live builds, but were the only things worth porting back. Frame times are now properly clamped on the client. Some testing revealed that the movement now feels identical to the live version of the game, which was the target. This commit also fixes a bug in CL_Move were the datagram was not send, and the next cmd time wasn't set if the client was NOT active, while it should have.
Function 'CL_Move' has been fully rebuild in the SDK. Originally, the game checked if the delta time exceeded an amount defined by an immediate value, and dropped usercmd's if that was the case. This logic has been replaced with a more dynamic solution, and the console variable regulating this ('fps_input_max') is set to 200.0 by default (the same as the fix applied in the Season 9.1 Genesis update). This function also has been slightly optimized by removing duplicate operations that were performed in the original function. A second fix has been applied to 'CInput::JoyStickApplyMovement' that was also found changed in the Season 9.1 Genesis executable. In that function, an extraneous clamp was performed on the frame time causing viewstick problems when usercmd's get dropped in CL_Move.
This commit fixes an engine bug where netmessages are getting copied into the replay buffer, while these messages should never be replayed. The engine performs an internal check on 'CNetMessage::m_nGroup', and if its NOT 2, the message is getting copied into the replay buffer. All messages returning false in 'ShouldReplayMessage' are not getting copied into the replay buffer anymore. This exploit has been used in the past to route clients that were watching a replay to an arbitrary server, which essentially forms an info leak as the client attempts to connect to the arbitrary server on its own. The exploit also allows for some form of remote code execution, depending on if the client was launched in developer mode or not.
Set the persistence fields to 'ready' in 'CClient::ActivatePlayer', before executing the rest of the function. Previously, it was set in 'CVEngineServer::PersistenceAvailable', but this is too late. The function 'FairFight_Init' was actually 'CClient::ActivatePlayer', and thus it has been moved to the correct file, and the old file defining it previously has been removed.
* 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!
Properly decouple squirrel and game code. This makes it easier to reverse engineer more of this squirrel system, and to compile them as individual libraries later on when moving to CMake to significantly decrease compile times.
Rebuilds SV_BroadcastVoiceData with an additional check of "sv_alltalk" cvar to disable team checking, allowing for servers to enable global voice chat
Fixed crash due to destructor of CSocketCreator being called during shutdown. If the socket fails to close, an error is logged. But at this point, all sockets have been closed already and the logger system has already been destroyed. Allocated as dynamic memory to avoid destructor being called at this stage.
* 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 uncontrolled format specifier in 'NetMsg' call on the RCON client.
* Removed extraneous call to 'PrintPercentageEscape'.
* Compare, and disable RCON logs if user attempts to connect to listen server's RCON.
Pruned many compiler warnings by removing the packing directive and alignment modifiers. Padding that was otherwise performed by the modifiers, have been added manually. This change did not affect code generation.
RCON upgrade with additional logging system improvements:
* Netconsole's can now log received messages in color, even when the RCON server has ANSI colors disabled; logs are fully composed locally.
* RCON server now also sends the log type over the wire, along with the (already existing) context.
* SDK logging code is now shared with the standalone netconsole application.
* Improved logging readability for the standalone netconsole application.
Changed all loggers to use the internal 'CoreMsg/CoreMsgV' functions. Significantly reduced duplicate code and CPU time. Code is also much more robust.
* Code now only acquires mutex lock when the actual logging part takes place.
* Code now only checks and strip ANSI rows if its enabled to begin with.
* Code now supports setting log levels, which ultimately could be tweaked with a cvar.
* Changed logger and file names to be more readable.
TODO:
* The RCON protocol has to be modified to accommodate these changes.
