Ryan Houdek 0b7587768d Unifies 32bit and 64bit clone implementation 
Syscall entry points still have different argument orders,
Moves the arguments to the clone3 argument structure and passes to generic handler.
Also implements clone3 while doing this

Ryan Houdek d115a57fe6 Implements support for execveat 2021-05-27 22:59:57 -07:00
Ryan Houdek 4c74478610 Implements iouring syscalls 
This is a very simple initial implementation.
io_uring allows some things that are hard to capture like setting personalities.

Assume sane usage for now

Ryan Houdek 9d44dfdca6 Actually updated the hardcoded guest kernel locations 
Just a couple of files and uname syscall
 2021-05-27 22:59:47 -07:00
Ryan Houdek a7858f4d37 Calculates a guest kernel version for FEX instead 
Takes the host kernel version and makes sure it fits in our supported kernel range
Minimum kernel version FEX reports to the guest is 5.0
Maximum kernel version FEX reports to the guest is currently 5.12

Ryan Houdek 6b3b10f8ae Implements pidfd_send_signal syscall 
Now that we know when to forward a siginfo_t to the guest, we can allow this syscall

Ryan Houdek 912d019ad8 Implements pidfd_getfd syscall 
Rise of the Tomb Raider launcher uses this without checking host kernel version.
Might be part of their crash handler.

Ryan Houdek 822a08f271 FEXConfig: Allow lower GL versions 
Automatically fall back through older GL versions

This allows us to freely support GL 3.0, 2.1 and ES 2.0.
Should fix an issue where Pi devices don't support GL 3.0 in all configs

External imgui had to be updated to fix an issue with ES 2.0

Fixes #1036

Ryan Houdek 94f464e1a4 Fix fadvise64 
posix variant still doesn't quite match the actual syscall implementation
 2021-05-11 18:39:00 -07:00
Ryan Houdek dfb15aaeb9 ppoll fixes 
glibc implementation makes a copy of the timeout and the kernel is expected to update it
Can't use the glibc implementation because of this.

Ryan Houdek 565f0e6af3 Handle FD flag remapping correctly 
FD flag remapping was broken. It would remap one flag on to another and then the next check would remap it back.

Instead keep a mask of the flags to be remapped then remap them all at the end.
Also goes through the ops and fixes a few cases where it was remapping wrong flags.

Ryan Houdek b03554bb7d Sigaction fixes 
Check for invalid sigsetsize

Since we are using SignalDelegator we don't use errno, so just return Result and check for Result == 0

Ryan Houdek 7b8cb5107a Emulate MAP_32BIT in mmap 
If we are on AArch64 then MAP_32BIT doesn't exist.
Emulate it by setting the address as a hint to the kernel so it scans bottom up

Ryan Houdek e282fd2221 Merge pull request #1016 from Sonicadvance1/ioctl32_micro_optimization 
Microoptimization for the DRM ioctls
 2021-05-10 21:14:16 -07:00
Ryan Houdek 83b4188569 Microoptimization for the DRM ioctls 
For DRM applications have a three FD deep MRU cached for faster lookups of FD to DRM handlers.
In a completely DRM ioctl bound situation like es2gears or GL application without threaded context
Then this puts us /nearly/ at the performance of calling the ioctl32 handler directly.
Sadly there is overhead that can't be overcome so this is the best that can be done from userland

Ryan Houdek 19e45544fb Handles symlinks in rootfs in openat 
This fixes an issue where rootfs has symlinks to other things in the rootfs so we need to track it through.

Relies on #1009 to be merged first.
Fixes any application that relies on libblas, mpv for example.
