[PATCH 0/2] ima: extending IMA policy to support interpreters

From: Mimi Zohar

On file open, the kernel has no way of differentiating between files
containing data and those with code that will be executed. Only the
interpreter knows how the file will be used. To bridge this gap, this
patch set extends the IMA policy language:

- to identify files with the executable mode bit set
- to support the new file open flag MAY_OPENEXEC introduced by Mickael
Salaun's "[PATCH v3 0/5] Add support for RESOLVE_MAYEXEC" patch set.

ima: add policy support for identifying file execute mode bit
ima: add policy support for the new file open MAY_OPENEXEC flag
