Subject: [v11-ima PATCH 23/25] NET: Add SO_PEERCONTEXT for multiple LSMs
Date: Wed, 27 Nov 2019 13:37:16 -0800	[thread overview]
Message-ID: <20191127213718.18267-24-casey@schaufler-ca.com> (raw)
In-Reply-To: <20191127213718.18267-1-casey@schaufler-ca.com>

The getsockopt SO_PEERSEC provides the LSM based security
information for a single module, but for reasons of backward
compatibility cannot include the information for multiple
modules. A new option SO_PEERCONTEXT is added to report the
security "context" of multiple modules using a "compound" format

        lsm1\0value\0lsm2\0value\0

This is expected to be used by system services, including dbus-daemon.
The exact format of a compound context has been the subject of
considerable debate. This format was suggested by Simon McVittie,
a dbus maintainer with a significant stake in the format being
usable.
