Subject: Re: [PATCH] net:ppp: replace too strict capability restriction on

From: Shanker Wang <>

> This patch removes the check for CAP_NET_ADMIN in the initial namespace
> when opening /dev/open. Instead, CAP_NET_ADMIN is checked in the user
> namespace the net namespace was created so that /dev/ppp cat get opened
> in a unprivileged container.
