fs-verity: support reading signature with ioctl (2021-02-07 14:51:19 -0800)
----------------------------------------------------------------
Add an ioctl which allows reading fs-verity metadata from a file.
This is useful when a file with fs-verity enabled needs to be served
somewhere, and the other end wants to do its own fs-verity compatible
verification of the file. See the commit messages for details.
This new ioctl has been tested using new xfstests I've written for it.
----------------------------------------------------------------
Eric Biggers (6):
fs-verity: factor out fsverity_get_descriptor()
fs-verity: don't pass whole descriptor to fsverity_verify_signature()
fs-verity: add FS_IOC_READ_VERITY_METADATA ioctl
fs-verity: support reading Merkle tree with ioctl
fs-verity: support reading descriptor with ioctl
fs-verity: support reading signature with ioctl
