Re: [PATCH bpf-next v5 4/9] bpf: Implement cgroup sockaddr hooks for unix sockets

That would be great! I think it makes sense to apply the same concept to unix
sockets so insulating changes to the msg_namelen seems like the way to go.

Just sent a new version of my patch series with this change, so we'll see how
it goes.

This is not yet allowed. We only allow changing the unix sockaddr length at the
moment. Maybe in the future we'd want to allow changing INET6 addr lengths
as well but currently we don't allow this.

Ack. Just curious, as I don't think it would be good to, e.g., have a connect4
hook modifying the address length for an IPv4 address.
