Subject: [PATCH v2 047/109] virtiofsd: use /proc/self/fd/ O_PATH file descriptor
Date: Tue, 21 Jan 2020 12:23:31 +0000 [thread overview]
Message-ID: <20200121122433.50803-48-dgilbert@redhat.com> (raw)
In-Reply-To: <20200121122433.50803-1-dgilbert@redhat.com>
From: Stefan Hajnoczi <stefanha@redhat.com>
Sandboxing will remove /proc from the mount namespace so we can no
longer build string paths into "/proc/self/fd/...".
Keep an O_PATH file descriptor so we can still re-open fds via
/proc/self/fd.
