From: Mimi Zohar <zohar@linux.ibm.com> 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 Signed-off-by: Mimi Zohar <zohar@linux.ibm.com> Reviewed-by: Lakshmi Ramasubramanian <redacted> Acked-by: Mickaël Salaün <mic@digikod.net>(Process nit: if you're sending this on behalf of another author, then this should be Signed-off-by rather than Acked-by.)I'm not a co-author of this patch.from Documentation/process/submitting-patches.rst: The Signed-off-by: tag indicates that the signer was involved in the development of the patch, or that he/she was in the patch's delivery path. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
OK, I though such tag had to go along with the From/Author, the Committer or a Co-developed-by tag, but there is also this specific case. I'll fix that in the next series.
