It’s actually good that the Btrfs receive failed because the send had an unlabeled security context—kind of a validation, even though it wasn’t intentional. The fix here fits the objective of the test case. Reviewed-by: Anand Jain <anand.jain@xxxxxxxxxx>
Setting the security label file attribute fails due to the default mount option implied by fstests: MOUNT_OPTIONS -- -o context=system_u:object_r:root_t:s0 /dev/sdb /mnt/scratch See commit 3839d299 ("xfstests: mount xfs with a context when selinux is on") fstests by default mount test and scratch devices with forced SELinux context to get rid of the additional file attributes when SELinux is enabled. When a test mounts additional devices from the pool, it may need to honor this option to keep on par. Otherwise failures may be expected. Moreover this test is perfectly fine labeling the files so let's just disable the forced context for this one.And of course I forgot to remove this sentence. Please, remove it if you decide to merge this fix.
Fixed the changelog and pushed it (for-next). Thanks, Anand
