[v2,0/4] Test the FS_IOC_READ_VERITY_METADATA ioctl

Message

This patchset adds tests for the FS_IOC_READ_VERITY_METADATA ioctl
(https://lkml.kernel.org/linux-fscrypt/[e-mail]/T/#u).

Running these tests requires a kernel at commit f7b36dc5cb37 or later
for FS_IOC_READ_VERITY_METADATA support, and fsverity-utils at commit
cf8fa5e5a7ac or later for 'dump_metadata' subcommand support.

Like the other fs-verity tests, they also require an ext4 or f2fs
filesystem, and CONFIG_FS_VERITY=y.  The second test also requires
CONFIG_FS_VERITY_BUILTIN_SIGNATURES=y.

As usual the tests will skip themselves if the prerequisites aren't met.

Changed v1 => v2:
   - Updated cover letter and removed RFC tag, now that the kernel and
     fsverity-utils patches have been merged.
   - Added executable bit to generic/902.
   - Improved some comments in common/verity.

Eric Biggers (4):
  generic: factor out helpers for fs-verity built-in signatures
  generic: add helpers for dumping fs-verity metadata
  generic: test retrieving verity Merkle tree and descriptor
  generic: test retrieving verity signature
