From: Eric Biggers <ebiggers@xxxxxxxxxx>
xfstests is supposed to disable the creation of SELinux xattrs because
this interferes with some tests (e.g. generic/062 and generic/377), but
this was not working on Android. For the android-xfstests portion of
the fix, make the following changes:
1. To stop the mount program from stripping the 'context' mount option,
mount selinuxfs and create an empty /etc/selinux/config. This makes the
is_selinux_enabled() function from libselinux return true.
2. To stop xfstests from thinking that SELinux is disabled, link
/usr/sbin/selinuxenabled to /bin/true. (Note: getting the real version
of selinuxenabled by adding selinux-utils to the chroot tarball would
also work, though no other programs from it are needed yet, and some
don't work in the chroot environment yet.)
In combination with the xfstests patch to stop hard-coding SELinux
contexts in xfstests, this fixes the failing tests.
