linux-toradex.git/include/uapi/linux/fsverity.h, branch v5.10-rc3 Linux kernel for Apalis and Colibri modules fs-verity: add SHA-512 support 2019-08-13T02:33:50+00:00 Eric Biggers ebiggers@google.com 2019-07-22T16:26:23+00:00 add890c9f9d2d1d79184ded72f23b37b164fc673 Add SHA-512 support to fs-verity. This is primarily a demonstration of the trivial changes needed to support a new hash algorithm in fs-verity; most users will still use SHA-256, due to the smaller space required to store the hashes. But some users may prefer SHA-512. Reviewed-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Jaegeuk Kim <jaegeuk@kernel.org> Signed-off-by: Eric Biggers <ebiggers@google.com>

fs-verity: add UAPI header 2019-07-28T23:59:16+00:00 Eric Biggers ebiggers@google.com 2019-07-22T16:26:20+00:00 085771ec14b9bdb843fe9283d4703ced395d1b0b Add the UAPI header for fs-verity, including two ioctls: - FS_IOC_ENABLE_VERITY - FS_IOC_MEASURE_VERITY These ioctls are documented in the "User API" section of Documentation/filesystems/fsverity.rst. Examples of using these ioctls can be found in fsverity-utils (https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/fsverity-utils.git). I've also written xfstests that test these ioctls (https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/xfstests-dev.git/log/?h=fsverity).
