fs/verity/signature.c

11  * signatures with fs-verity, and the alternatives (such as userspace signature
25  * If 1, all verity files must have a valid builtin signature.
38  * fsverity_verify_signature() - check a verity file's signature
40  * @signature: the file's built-in signature
41  * @sig_size: size of signature in bytes, or 0 if no signature
43  * If the file includes a signature of its fs-verity file digest, verify it
46  * Return: 0 on success (signature valid or not required); -errno on failure
