Subject: Re: Should setting the listen-port require CAP_SYS_ADMIN in the socket namespace?
Date: Sun, 9 Sep 2018 11:40:32 +0200 [thread overview]
Message-ID: <cbe7e13a-3155-ded7-9dc1-3c8f467d909b@gmail.com> (raw)

To be clear: The solution described for the transit-net case also applies to
the listen-port case:
Trying to change listen-port and/or transit-net should require CAP_SYS_ADMIN
in the transit namespace unless the user also proves access to that namespace
by passing an UDP socket from that namespace in the same call.
