Subject: [PATCH] IMA: measure.policy: limit dont_measure tmpfs policy to func=FILE_CHECK
Date: Mon, 3 Feb 2025 22:02:33 +0100 [thread overview]
Message-ID: <20250203210233.1407530-1-pvorel@suse.cz> (raw)
add func=FILE_CHECK to dont_measure tmpfs
Similarly to tcb.policy limit dont_measure tmpfs policy to func=FILE_CHECK.
This allows to do extra measurements, e.g. kexec boot command line, see
kernel commit
7eef7c8bac9a ("ima: limit the builtin 'tcb' dont_measure tmpfs policy rule")
Also remove leading 0 from tmpfs magic (to match IMA docs and tcb.policy).
