      GLX: Remove the XESetCloseDisplay callback during teardown. · 4a08df7b
      Kyle Brenneman authored 
      When libGLX.so is unloaded, call XESetCloseDisplay to remove the display close
callback for any displays that still exist.

Otherwise, if libGLX.so is loaded using dlopen, and then unloaded while a
display is still open, then XCloseDisplay would try to call the (now dangling)
callback.

      GLdispatch: Add a build option to disable entrypoint patching. · c1c60ac8
      Kyle Brenneman authored 
      Added a --disable-entrypoint-tracking configure option and an
'entrypoint-patching' meson option to disable libGLdispatch's entrypoint
patching at build time.

If entrypoint patching is disabled, then it #ifdef's out the mprotect call, and
acts as if mprotect had failed, which causes libGLdispatch to skip trying to
perform any patching.

Fixes glvnd/libglvnd#217

      GLX: Fix a potential deadlock in OnDisplayClosed. · dd2d28a0
      Kyle Brenneman authored 
      In OnDisplayClosed, unlock the __glXDisplayInfoHash lock before locking
glxContextHashLock.

In CommonMakeCurrent, it holds glxContextHashLock while it tries to take the
__glXDisplayInfoHash lock, so if CommonMakeCurrent and OnDisplayClosed run at
the same time, they could deadlock.

To avoid that, OnDisplayClosed will set a new inTeardown flag in the
__GLXdisplayInfoHash, then it will unlock the display hash before calling
__glXDisplayClosed.

After __glXDisplayClosed is finished, OnDisplayClosed will lock
__glXDisplayInfoHash again long enough to remove the display from the
hashtable.

The inTeardown flag tells __glXLookupDisplay to return NULL, since after that
point, nothing should be trying to look up the display. In principle, we could
just remove the display from the hashtable up front, but then if something did
try to look up the display, then __glXLookupDisplay would try to create a new
__GLXdisplayInfo for it.

Fixes glvnd/libglvnd#213

      egl: use device dispatch if at least one vendor suceeds · a527411d
      Ronan Pigott authored 
      Currently, in InitDeviceListInternal if any egl vendor fails to list
its devices for any reason the construction of the device list is
abandoned. That means that even if we have one vendor successfully
serving the application, the failure of another vendor library will
break any api calls related to egl devices.

Instead, if a vendor fails queryDevicesEXT the device mapping logic
should proceed as if it listed no devices. If the relevant device
belongs to the failed vendor then the dispatch will still fail with
EGL_BAD_DEVICE.

      Add .arm directives for the GLX entrypoint stubs. · 6cd95fbf
      Kyle Brenneman authored 
      Add .arm and .thumb directives before and after the ARMv7 GLX dispatch stubs.

The function addresses that get passed around don't take Thumb into account, so
if they're compiled as Thumb, then they'd still get executed as ARM, which
would cause them to crash a SIGILL.
