Subject: [PATCH 0/2] virtiofsd: drop Linux capabilities(7)
Date: Thu, 16 Apr 2020 17:49:05 +0100 [thread overview]
Message-ID: <20200416164907.244868-1-stefanha@redhat.com> (raw)
virtiofsd doesn't need of all Linux capabilities(7) available to root. Keep a
whitelisted set of capabilities that we require. This improves security in
case virtiofsd is compromised by making it hard for an attacker to gain further
access to the system.
Stefan Hajnoczi (2):
virtiofsd: only retain file system capabilities
virtiofsd: drop all capabilities in the wait parent process
