Subject: [PATCH net-next v3 0/4] sock_diag: monitor packet sockets

The goal of this patchset is to be able to monitor packet sockets.
The two first patches add new attributes for packet_diag subsystem, so that all
information exported via the /proc/net/packet are also exported via netlink.
The third patch avoid to disclose socket pointer to all user. Via the /proc,
kptr_restrict is used.
The last patch allows allowed users to get details about filter attached to a
packet socket.

As usual, the patch against iproute2 will be sent once the patches are included
and net-next merged. I can send it on demand.

v2: add sock_diag_notify_del() to avoid confusion of the meaning of the second
    arg of __sock_diag_notify()
    enhance commitlog of patch 3/5

v3: drop previous 4/5 and 5/5 patches
    add patch 3/4 (sock_diag: do not disclose sock ptr to all users)
    disclose filters only to allowed users
