Bug ID: 110328
Summary: meson-built drivers are installed with non-empty rpath
Product: Mesa
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Other
Assignee: mesa-dev@lists.freedesktop.org

This is terrible:
datura:~% readelf -d /usr/lib64/dri/radeonsi_dri.so | grep RPATH
0x000000000000000f (RPATH) Library rpath:
[$ORIGIN/../../../mesa:$ORIGIN/../../../compiler/glsl:$ORIGIN/../../../compiler/glsl/glcpp:$ORIGIN/../../../util:$ORIGIN/../../../compiler/nir:$ORIGIN/../../../compiler:$ORIGIN/../../../mesa/drivers/dri/common:$ORIGIN/../../state_trackers/dri:$ORIGIN/../../auxiliary:$ORIGIN/../../../mapi/shared-glapi:$ORIGIN/../../auxiliary/pipe-loader:$ORIGIN/../../../loader:$ORIGIN/../../winsys/sw/null:$ORIGIN/../../winsys/sw/wrapper:$ORIGIN/../../winsys/sw/dri:$ORIGIN/../../winsys/sw/kms-dri:$ORIGIN/../../drivers/llvmpipe:$ORIGIN/../../drivers/softpipe:$ORIGIN/../../drivers/r300:$ORIGIN/../../winsys/radeon/drm:$ORIGIN/../../drivers/r600:$ORIGIN/../../drivers/radeonsi:$ORIGIN/../../winsys/amdgpu/drm:$ORIGIN/../../../amd/addrlib:$ORIGIN/../../../amd/common:$ORIGIN/../../winsys/nouveau/drm:$ORIGIN/../../drivers/nouveau:$ORIGIN/../../drivers/svga:$ORIGIN/../../winsys/svga/drm:$ORIGIN/../../drivers/virgl:$ORIGIN/../../winsys/virgl/drm:$ORIGIN/../../winsys/virgl/vtest]
This is _probably_ not a security problem, since in most cases $ORIGIN is going
to be /usr/lib/dri, and /usr and / aren't generally world-writable. But it is a
performance problem, because when the 3D driver loads any libraries it depends
on that aren't already loaded (llvm, probably) will be uselessly searched for
in a bunch of nonexistent directories. Not theoretical either, see:
https://gitlab.freedesktop.org/wayland/weston/issues/213
In Fedora I'm going to work around this for now by doing 'chrpath -d' on the
drivers after they're installed, but this should be addressed upstream too.
