This adds ambient capabilities. See the individual patch changelogs
for details.
Preliminary userspace code is here:
https://git.kernel.org/cgit/linux/kernel/git/luto/util-li...
I'll follow up with a rough draft of a man-pages patch.
Changes from v1:
- Lots of cleanups to the ambient cap code.
- The securebit is new.
Andy Lutomirski (2):
capabilities: Ambient capabilities
capabilities: Add a securebit to disable PR_CAP_AMBIENT_RAISE
