Subject: [PATCH v2 0/2] capabilities: Ambient capabilities
Date: Thu, 14 May 2015 23:39:47 -0700 [thread overview]
Message-ID: <cover.1431671529.git.luto@kernel.org> (raw)
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-linux-playground.git/commit/?h=cap_ambient&id=7f5afbd175d2
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
