This is a preparation patch for the module auto-load restriction feature.
In order to restrict module auto-load operations we need to check if the
caller has CAP_SYS_MODULE capability. This allows to align security
checks of automatic module loading with the checks of the explicit operations.
How
Previous patches added the global sysctl "modules_autoload_mode". This patch
make it possible to support process trees, containers, and sandboxes by
providing an inherited per-task "modules_autoload_mode" flag that cannot be
re-enabled once disabled. This allows to restrict automatic module loading
documentation and code comments.
All suggestions were improved and fixed. Please see changelog for more
details.
These patches are against next-20170522

Currently, an explicit call to load or unload kernel modules require
