Subject: [PATCH] disallow modular capabilities
Date: Sun, 2 Jan 2005 21:00:32 +0100 [thread overview]
Message-ID: <20050102200032.GA8623@lst.de> (raw)
There's been a bugtraq report about a root exploit with modular
capabilities LSM support out for more than a week.
This patch fixes it the hard way by disallowing to build the code
modular. In fact I think allowing modular security policies is a
really, really bad idea because loading it after boot loses far
too much state. Would you take a patch killing the exports in
security/ ?

If you are unsure how to answer this question, answer N.
config SECURITY_CAPABILITIES
- tristate "Default Linux Capabilities"
+ bool "Default Linux Capabilities"
depends on SECURITY
help
This enables the "default" Linux capabilities functionality.
