Consider the following transcript: $ keyctl add trusted kmk "new 32 blobauth=helloworld keyhandle=80000000 migratable=1" @u add_key: Invalid argument The documentation has the following description: migratable= 0|1 indicating permission to reseal to new PCR values, default 1 (resealing allowed) The consequence is that "migratable=1" should succeed. Fix this by allowing this condition to pass instead of return -EINVAL. [*] Documentation/security/keys/trusted-encrypted.rst Cc: stable@vger.kernel.org Cc: "James E.J.
