The kernel has no way of differentiating between a file containing data
or code being opened by an interpreter. The proposed O_MAYEXEC
openat2(2) flag bridges this gap by defining and enabling the
MAY_OPENEXEC flag.
This patch adds IMA policy support for the new MAY_OPENEXEC flag.
Example:
measure func=FILE_CHECK mask=^MAY_OPENEXEC
appraise func=FILE_CHECK appraise_type=imasig mask=^MAY_OPENEXEC
