Package: nvidia-kernel-dkms
Version: 375.82-4
Severity: normal
Tags: patch
I have a vanilla kernel with CONFIG_GCC_PLUGINS, CONFIG_GCC_PLUGIN_STRUCTLEAK
and CONFIG_GCC_PLUGIN_RANDSTRUCT and conftest fails because KBUILD_CFLAGS
contains the following:
-fplugin=./scripts/gcc-plugins/structleak_plugin.so
-fplugin=./scripts/gcc-plugins/randomize_layout_plugin.so
but conftest runs with a different pwd than the module build itself.
I'm attaching a patch inspired by
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/scripts/Kbuild.include?h=v4.13.7#n118
that fixes the build.
