KEYS: trusted: Fix migratable=1 failing
commit 8da7520c80468c48f981f0b81fc1be6599e3b0ad upstream.
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.
