[PATCH net-next v3 0/4] net: Introducing socket mark receive socket option

[Eyal Birger]

This patch set introduces a new socket option for fetching the mark
of skbs passed to sockets as ancillary data.

A userspace program may wish to receive the mark of packets it
receives, for example for distinguishing between different TPROXY
diversion rules to the same userspace proxy socket.

The patch set includes a minor function renaming, as well as a
change in struct sk_buff for allowing skb->mark to persist after
being queued to the socket queue.

---
Changes in v3:
- Rebase
- Set skb->priority immediately prior to transmittion in IGMPv3/MLD
- Extended commit message regarding use of skb->priority instead of
  skb->mark in struct sk_buff union
Changes in v2:
- Function parameter indentation
- Commit message formatting

Eyal Birger (4):
  net: Rename sock_recv_ts_and_drops() to sock_cmsg_recv()
  ipv4,v6: avoid setting skb->priority when skb->reserved_tailroom is in
    use in igmpv3/mld
  net: use skb->priority for overloading skb->dropcount and
    skb->reserved_tailroom instead of skb->mark
