Add tests for fs-verity, a new feature for read-only file-based authenticity protection. fs-verity will be supported by ext4 and f2fs, and perhaps by other filesystems later. Running these tests requires: - A kernel with the fs-verity patches applied and configured with CONFIG_FS_VERITY. Specifically, this version of the xfstests patchset is compatible with version 6 of the kernel patchset, which can be retrieved from tag "fsverity_2019-07-01" of https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git - The fsverity utility program from https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/fsverity-utils.git It needs to be commit 2151209ce1da or later. - e2fsprogs v1.45.2 or later for ext4 tests, or f2fs-tools v1.11.0 or later for f2fs tests. Example with kvm-xfstests: $ kvm-xfstests -c ext4,f2fs -g verity For more information about fs-verity, see the file Documentation/filesystems/fsverity.rst from the kernel patchset. This version of the xfstests patchset can also be retrieved from tag "fsverity_2019-07-01" of https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/xfstests-dev.git Changed since v2 (Jun. 2019): - Updated the signature verification test (generic/905) to match the latest kernel and fsverity-utils changes. - Added _fsv_sign() utility function. - Correctly skip the fs-verity tests on ext3-style filesystems. Changed since v1 (Dec. 2018): - Updated all tests to use the new fs-verity kernel API. - Many cleanups, additional checks in the tests, and other improvements. - Addressed review comments from Eryu Guan. - Added a test for the built-in signature verification feature. - Removed the fs-verity descriptor validation test, since the on-disk format of this part was greatly simplified and made fs-specific.
