ima: extend "mask" policy matching support
commit 4351c294b8c1028077280f761e158d167b592974 upstream. The current "mask" policy option matches files opened as MAY_READ, MAY_WRITE, MAY_APPEND or MAY_EXEC. This patch extends the "mask" option to match files opened containing one of these modes. For example, "mask=^MAY_READ" would match files opened read-write.
