NAME

     verifiedexec - Verified exec signature loader device


SYNOPSIS

     options VERIFIED_EXEC
     pseudo-device verifiedexec 1


DESCRIPTION

     The verifiedexec driver provides a method of loading the fingerprints
     used by the verified exec feature.  The fingerprints are loaded by open-
     ing verifiedexec and then using the VERIEXECLOAD ioctl to feed the fin-
     gerprints into kernel space.  Note that the loading should only be done
     after a mount of all file systems that contain files which have finger-
     prints associated with them.  Signatures may only be loaded when the ker-
     nel securelevel is set to 0.


ERRORS

     The verifiedexec device will return EPERM if securelevel is greater than
     0.  An ENOENT error will be returned if the file path passed in does not
     exist.
