From: Mickaël Salaün
Date: Wed Nov 11 2020 - 16:34:49 EST


Hi,

This patch series fixes some issues and makes the Landlock filesystem
access-control more consistent and deterministic when stacking multiple
rulesets. This is checked by current and new tests. I also extended
documentation and example to help users.

This series can be applied on top of
https://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security.git/log/?h=landlock_lsm

Regards,
